The present disclosure provides a table top range hood. As illustrated into, in some embodiments, the table top range hood includes a duct housinghaving an air inlet, the air inletfacing a first orientation; a light-transmitting coverbeing connected to the duct housingand defining an accommodation cavitytogether with the duct housing; and a light-emitterdisposed in the accommodation cavityand adapted to emit light, the light emitted by the light-emitterbeing adapted to pass through the light-transmitting coverand irradiate towards the first orientation.

By disposing the light-emitter, the air inletopens towards the first orientation and the light emitted by the light-emitterirradiates towards the first orientation. In this way, a user can easily observe an extraction effect, providing reference for adjusting a position of the table top range hood. Further, by disposing the light-emitter, the table top range hood is suitable for use in the outdoor without lights or under low-light conditions. In addition, the light-emitteris disposed in the accommodation cavitydefined by the light-transmitting coverand the duct housingto prevent the light-emitterfrom being contaminated by the fume. Compared with cleaning the light-emitter, it is easier to clean the light-transmitting cover.

In an exemplary embodiment of the present disclosure, the table top range hood includes a range hood bodyand a machine body. The range hood bodyis mounted at the machine body. The machine bodyof the table top range hood is placed on a table, so that the range hood bodyis maintained at a predetermined distance from the table top. An assembly between the range hood bodyand the machine bodycan be referred to in the related art, which is not an improvement of the present disclosure, and thus will not be described in detail.

The range hood bodyincludes the duct housing, a support, a fan, the light-transmitting cover, and the light-emitter. The duct housingis provided with an air duct. The duct housingmay be integrally formed or may be formed by connecting at least two parts. The air ducthas an end constituting the air inletand another end constituting an air outlet. The supportis disposed in the air ductand fixed through connecting to the duct housing. There are many connection methods between the supportand the duct housing, such as welding, screwing, and engagement. It should be understood that the supportis a component for supporting other parts. The supportmay be processed by metallic materials or other materials. The supportmay have a regular shape or an irregular shape. In this embodiment, the supportis a sheet metal part, and the so-called sheet metal part is processed by a sheet metal process. The fanis connected to the supportso as to be fixed. In this case, the fanis located in the air ductand is located between the air inletand the air outlet. The fandrives the fume to enter the air ductfrom the air inletand to be discharged from the air outlet.

The air inletopens towards the first orientation. For example, taking the user facing the air inletas a reference, a side of the table top range hood facing the user is the front, a side facing away from the user is the rear, a side corresponding to the left hand of the user is the left, a side corresponding to the right hand of the user is the right, a side close to the table top is the lower, and a side facing away from the table top is the upper. The first orientation points to a front space of the table top range hood. That is, the table top range hood extracts the fume from the front space by the air inlet.

The light can pass through the light-transmitting cover. That is, the light-transmitting coverhas a transparent or translucent structure. The light-transmitting coveris connected to the duct housing, enabling the accommodation cavityto be formed between the light-transmitting coverand the duct housing. The light-emitteris disposed in the accommodation cavity. The light-emitteris a component that can emit the light. For example, with a common light-emitteras a lamp bead, the light-emittercan emit the light when the lamp bead is energized. The light emitted by the light-emittercan pass through the light-transmitting coverand irradiate towards the first orientation (i.e., irradiate towards the front space of the table top range hood). It should be understood that since the air inletopens towards the first orientation, when the table top range hood is in operation, the fume is extracted and flows from a space indicated by the first direction (the front space of the table top range hood) to the air inlet. In this case, the light emitted by the light-emitterpasses through the light-transmitting coverand irradiates towards the space indicated by the first direction (the front space of the table top range hood). The light can be reflected and refracted when passing through the light-transmitting cover. Due to presence of a large number of oil mist particles in the fume, the light encounters these particles and undergoes reflection and refraction, in such a manner that the user can observe a flow direction of the fume and the extraction effect of the fume is visually presented to the user.

It should be understood that since the table top range hood is easy to carry, it is necessary to adjust the table top range hood to a suitable position when using the table top range hood. Through the above arrangement, since the user can directly observe the extraction effect of the fume, adjusting the table top range hood to the suitable position can be facilitated for the user. Precisely, by disposing the light-emitter, which is suitable for use in the outdoor without lights or a dim environment, a lighting effect can also be provided.

It should be noted that the table top range hood can produce oil adhesion during extracting the fume. In this embodiment, the light-emitteris disposed in the accommodation cavitydefined by the light-transmitting coverand the duct housing. It is difficult for the fume to enter the accommodation cavityto prevent the light-emitterfrom being contaminated by the fume. Even if the fume contaminates the light-transmitting cover, it is much more convenient for the user to clean the light-transmitting coverthan to clean the light-emitter.

As illustrated in,,, and, in some embodiments, the air inletis surrounded by the accommodation cavity. In this way, the light can be emitted towards the first orientation in a direction surrounding the air inlet, improving coverage of the light. Therefore, flow of the fume can be easily observed when the fume is extracted. Since the accommodation cavityis defined by the light-transmitting coverand the duct housing, the light-transmitting coveralso needs to surround the air inlet. For example, in the structure illustrated in, the light-transmitting coveris of a circular ring shape and mounted at an air inlet end of the duct housing. When the light-emitteremits the light, the table top range hood can form a light-emitting ring to improve an irradiation range of the fume, further facilitating observation of the flow of the fume for the user.

Further, on the premise that the light-transmitting coveris also designed to surround the air inlet, as illustrated in,,, and, in some embodiments, the light-transmitting coveris tapered in a flow direction of fume, which can provide flow guidance for the fume entering the air inlet, reducing turbulence at the air inlet, and thus is conducive to improving the extraction effect of the fume and reducing noise.

As illustrated in, in some embodiments, the light-emitteris of a strip shape and is arranged in an extension direction of the accommodation cavity.

In an exemplary embodiment of the present disclosure, the strip-shaped light-emitterconstitutes a lamp strip, which may include a plurality of lamp beads. The light-emitteris arranged in the extension direction of the accommodation cavity, that is, surrounding the air outlet. Therefore, a corresponding light source exists in the direction surrounding the air outlet, to emit the light passing through the light-transmitting cover, further improving intensity of light emission, which is more conducive to improving an illumination effect.

As illustrated in,,, and, in some embodiments, the duct housinghas a recess. The light-transmitting covercovers the recessand defines the accommodation cavitytogether with the recess. The light-emitteris connected to a recess wall of the recess.

In an exemplary embodiment of the present disclosure, with reference to an orientation illustrated in, the recessof the duct housingopens towards the front. During assembly, the light-emittercan be connected to the recess wall of the recessto realize fixation of the light-emitter. Then, the light-transmitting covercan be connected to the duct housingand cover the recessto define the accommodation cavitybetween the light-transmitting coverand the duct housing(the recessis at least part of the accommodation cavity) to form protection for the light-emitter. It can be understood that the light-transmitting coveris a separate component to be mounted last. The light-emitteris first connected to the recess wall of the recessto be fixed, so as to facilitate wiring and power supply.

Further, as illustrated in, in some embodiments, the recess wall of the recessincludes a recess bottom walland recess side wallsrespectively located at two opposite sides of the recess bottom wall. Therefore, an opening is formed between the recess side wallson the two opposite sides of the recess bottom wall. As illustrated in, the recesshas an opening and opens towards the front. The light-emitteris mounted at the recess side wallat one side of the two opposite sides of the recess bottom wall. For example, the light-emitteris mounted at the recess side wallat a lower side of the orientation illustrated in, and emits the light towards the recess side wallat another side of the two opposite sides of the recess bottom wall(a recess side wallat an upper side). The light emitted by the light-emitteris reflected by the recess side wallat the other side of the two opposite sides of the recess bottom wall(the recess side wallat the upper side) and irradiates towards the first orientation. The light emitted by the light-emitteris further diverged after being reflected, improving light emitting uniformity of the light-transmitting cover.

As illustrated into, in some embodiments, the duct housingincludes a first housingand a mounting frame, and the mounting frameis connected to an inner wall of the first housingand the air inletis surrounded by the mounting frame. The light-transmitting coverconnects to the mounting frameand defines the accommodation cavitytogether with the mounting frame.

In an exemplary embodiment of the present disclosure, the first housingconstitutes a majority of the duct housing. The mounting frameis connected to an inner wall of an air inlet end of the first housing. The light-transmitting coveris connected to the mounting frame. The mounting frameand the first housing, as independent components, are connected and fixed to each other by means of a connection method. By designing the mounting frameas an independent component, mounting of connection structures at the mounting framecan be facilitated, especially in a case where various types of connection structures are disposed at the mounting frame. Compared to integral forming of the mounting frameand the first housing, this embodiment can effectively reduce manufacturing complexity. Further, when it is necessary to mounted other parts to an inside of the first housing, the mounting framemay be connected to the first housingafter mounting of these parts, so as to avoid interference.

There are various ways to connect the mounting frameto the first housing. For example, the mounting frameis snap-connected to the first housing, which is quick and easy without direct manipulation by the user as long as the mounting frameis controlled to align with a corresponding position of the first housingto move into place until the snap-connection occurs. In addition, since the mounting frameis connected to the inner wall of the first housing, the connection structures between the mounting frameand the first housingcan be concealed once the snap-connection is performed, which can avoid exposure of a connection mechanism. Similarly, the light-transmitting covermay also be designed to be snap-connected to the mounting frame.

As illustrated intoandto, in some embodiments, the table top range hood further includes a filterconfigured to filter the fume. The filteris located at a flow path of the fume. For example, the filteris disposed at an air inlet. When the fume enters the air inlet, the fume flows through the filterand is filtered by the filter, and then flows through the fanto be discharged. In this embodiment, the filteris connected to the mounting frame. That is, both the light-transmitting coverand the filterneed to be connected and fixed to the mounting frame. Since the mounting frameis the independent component with respect to the first housing, at the mounting framecan conveniently have a connection structure configured to connect to the light-transmitting coverand a connection structure configured to connect to the filter.

The mounting frameis provided with a first magnetic attraction portionand a first connection member. The filteris provided with a second magnetic attraction portionand a second connection portion. The first connection memberand the second connection portionare configured to be plug-connected to each other, and the first magnetic attraction portionand the second magnetic attraction portionare configured to be magnetically connected to each other, enabling the filterto be detachably connected to the mounting frame. Through plug-in connection between the first connection memberand the second connection portion, the filtercan be quickly positioned. Through magnetic connection between the first magnetic attraction portionand the second magnetic attraction portion, further fixation for the filtercan be realized. This structure is simple, effectively improving convenience of disassembly and assembly of the filter.

The filteraccumulates dirt and may become dirty even clogged after a period of use, hence requiring disassembly of the filterfor cleaning. In the related art, the filteris fixed by screwing in screws. That is, when installing the filter, screws need to be tightened to fix the filterin place. When disassembling the filter, the screws need to be loosened. The operation of tightening or loosening screws requires the user to control a screwdriver to turn the screws. Assembly and disassembly experience with this method remains to be improved. Therefore, in this embodiment, the first connection memberis disposed to be engaged with the second connection portion, and the first magnetic attraction portionis disposed to be engaged with the second magnetic attraction portion.

When the filteris mounted to the mounting frame, the second connection portionis controlled to be engaged with the first connection member. The engagement between the second connection portionand the first connection memberis realized in a form of plug-in connection. The second connection portionmay be inserted into the first connection memberor the first connection membermay be inserted into the second connection portion. Simply inserting one of the first connection memberand the second connection portioninto another of the first connection memberand the second connection portioncan achieve rapid positioning, which is convenient and quick. For example, when the first connection memberis a socket, the second connection portioncan be inserted into the socket to achieve a quick plug-in connection.

On a basis of the plug-in connection between the first connection memberand the second connection portion, the second magnetic attraction portionis controlled to be engaged with and the first magnetic attraction portion. Engagement between the second magnetic attraction portionand the first magnetic attraction portionis realized through being magnetically connected to each other. It can be that the first magnetic attraction portiongenerates a magnetic field to attract the second magnetic attraction portion, or it can be that the second magnetic attraction portiongenerates a magnetic field to attract the first magnetic attraction portion. Alternatively, both the first magnetic attraction portionand the second magnetic attraction portioncan generate the magnetic field to attract each other. On the basis of the plug-in connection between the first connection memberand the second connection portion, simply bringing the first magnetic attraction portionand the second magnetic attraction portionclose to each other enables their magnetic attraction connection, which is convenient and quick. For example, when the first magnetic attraction portionis a magnet, and the second magnetic attraction portionis also a magnet, both the first magnetic attraction portionand the second magnetic attraction portiongenerate the magnetic field, respectively, to enhance an attraction force of the magnetic attraction connection.

It is precisely through cooperation of the plug-in connection and the magnetic attraction connection that the disassembly of the filteris performed very conveniently. When the filteris removed from the mounting frame, the user grasps the filterand applies a force. The force applied by the user overcomes the attraction force between the first magnetic attraction portionand the second magnetic attraction portionto separate the first magnetic attraction portionand the second magnetic attraction portion. Then, the second connection portionis controlled to move in an opposite direction of an insertion direction to separate from the first connection member. In this way, the disassembly of the filteris completed, facilitating cleaning of the filter.

As illustrated intoandto, in some embodiments, the second connection portionis disposed at a side of a center of the filterand the second magnetic attraction portionis disposed at another side of the center of the filter. Therefore, when the filteris mounted to the mounting frame, connection points are formed at two opposite sides of the center of the filter, improving mounting stability of the filter.

Reference can be made to orientations of, positions of the second connection portionand the second magnetic attraction portionmay be as follows: the second connection portionmay be disposed at a left side of the filter, and the second magnetic attraction portionmay be disposed at a right side of the filter. Alternatively, the second connection portionmay be disposed at the right side of the filter, and the second magnetic attraction portionmay be disposed at the left side of the filter. Alternatively, the second connection portionmay be disposed at an upper side of the filter, and the second magnetic attraction portionmay be disposed at a lower side of the filter. It should be understood that the first connection memberand the first magnetic attraction portionneed to be disposed correspondingly regardless of where the second connection portionand the second magnetic attraction portionare disposed.

In some embodiments, the second connection portionis disposed at the lower side of the filter, and the second magnetic attraction portionis disposed at the upper side of the filter. When the filteris mounted at the mounting frame, the second connection portionis controlled to be plug-connected to the first connection member. Since the second connection portionis located at the lower side of the filter, the user can easily observe a relative position of the second connection portionand the first connection member, facilitating controlling the engagement between the second connection portionand the first connection member. After the plug-in connection between the second connection portionand the first connection member, the filtercan abut against the mounting frameunder an action of the force applied by the user and under an action of gravity. Therefore, the mounting frameis less likely to be loosened and separated. Further, the upper side of the filteris controlled to rotate towards the mounting frameand move closer, allowing the second magnetic attraction portionto gradually approach the first magnetic attraction portionuntil they are magnetically connected, further enhancing convenience of assembly and disassembly.

As illustrated into, in some embodiments, the mounting frameis provided with a stopperlocated downstream of the filter. The stopperis configured to abut with the filterduring mounting the filter, preventing the filterfrom continuing to move towards an inside of the air duct, and strengthening positioning of mounting of the filter.

In an exemplary embodiment of the present disclosure, it can be seen from the above that positioning can be provided only when the first connection memberis engaged with the second connection portion. By disposing the stopper, the stoppercan abut with the filterduring the mounting of the filterto prevent the filterfrom continuing to move along the air duct, facilitating alignment between the first connection memberand the second connection portion, which can strengthen the positioning. Since the stoppercan abut with the filter, the first magnetic attraction portioncan be disposed at the stopper. The filterand the stoppercan be magnetically attached together when the filterand the stoppercome into contact with each other.

As illustrated in, in some embodiments, the first connection memberis the socket. The second connection portionis inserted into the socket. The second connection portionhas an oil discharge opening. The filteris configured to discharge oil through the oil discharge opening.

In an exemplary embodiment of the present disclosure, during extracting the fume by the table top range hood, filtration of the fume by the filtercan produce the oil at the filter. The oil is a complex mixture including various organic matters and water. The oil flows downwardly along the filterunder the action of gravity, and is discharged through the oil discharge openingby disposing the oil discharge openingat the second connection portionon the basis that the second connection portionis inserted into the first connection member(the socket). It should be understood that the table top range hood includes an oil cupconfigured to be detachable. The oil discharged from the oil discharge openingfinally enters the oil cupfor temporary storage. The oil cupis designed to be detachable. When the table top range hood is used, the oil generated by the table top range hood is temporarily stored in the oil cup. When the oil cupneeds to be cleaned, the oil cupcan be removed from the table top range hood to allow the oil to be poured. After cleaning of the oil cupis completed, the oil cupcan be remounted back into the table top range hood.

As illustrated into, in some embodiments, the filterincludes a filter screenand a filter screen frame. The filter screen framehas an oil collecting groove. The second connection portionis disposed at the filter screen frame. In addition, the oil discharge openingis in communication with the oil collecting groove. The filter screenis disposed in the filter screen frameand located in the oil collecting groove.

In an exemplary embodiment of the present disclosure, the filter screen frameis a skeleton structure of the filterand configured to support the filter screen. The filter screenis disposed at the filter screen frameto be supported. The filter screenhas a porous structure, which can not only allow the fume to flow, but also filter the fume to obtain the oil. In this embodiment, the filter screen framehas an oil collecting groove. In addition, the filter screenis located at the oil collecting groove, and the filter screenis surrounded by the oil collecting groove. When the filter screenfilters the fume to obtain the oil, the oil flows along the filter screenuntil the oil enters the oil collecting groove. By disposing of the oil collecting groove, the oil separated from the filter screenis collected and then is discharged from the oil discharge opening.

As illustrated into, in some embodiments, the filter screen frameincludes a first frameand a second frame. The first frameand the second frameare connected to each other to clamp the filter screento support the filter screen. In addition, after the first frameand the second frameare connected and fixed to each other, the oil collecting grooveis defined between the first frameand the second frame. In this way, assembly between the filter screen frameand the filter screencan be facilitated on the basis of forming the oil collecting groove. For example, an assembly process between the filter screen frameand the filter screenis as follows: the filter screenis placed at the first frame, and then the second frameis controlled to be connected to the first frame. After the second frameand the first frameare connected and fixed to each other, the filter screencan be fixed and the oil collecting groovecan be defined, in this case the filter screenis located in the oil collecting groove.

The first framecan be connected to the second framein many methods as long as connection and fixation between the first frameand the second framecan be ensured. For example, to improve convenience of connection between the first frameand the second frame, the first frameand the second frameare fixed with screws. As illustrated inand, one of the first frameand the second framehas an insertion slot, and another of the first frameand the second frameis provided with a plug-in portion. When the first frameis connected to the second frame, the plug-in portionis inserted into the insertion slot. On this basis, one of the first frameand the second frameis provided with a snap-fit, and the other of the first frameand the second frameis provided with a snap-fit position. When the first frameis connected to the second frame, the snap-fitis snap-connected to the snap-fit position. Assembly positioning is realized by cooperation between the plug-in portionand the insertion slot. Further, fixation is realized by cooperation between the snap-fitand the snap-fit position.

It should be understood that one of the first frameand the second framehas the insertion slot, and the other of the first frameand the second frameis provided with the plug-in portion. That is, when the first framehas the insertion slot, the second frameis provided with the plug-in portioncorrespondingly. When the first frameis provided with the plug-in portion, the second framehas the insertion slotcorrespondingly. When the first frameis provided with both the insertion slotand the plug-in portion, the second frameis provided with the plug-in portionand the insertioncorrespondingly. The same is true for arrangement of the snap-fitand the snap-fit position.

Since the second connection portionis disposed at the filter screen frame, and the filter screen frameincludes the first frameand the second frameconnected to each other, to facilitate communication between the oil discharge openingand the oil collecting groove, as illustrated inand, the second connection portionhas one part disposed at the first frameand another part disposed at the second frame. For example, part of the second connection portionand the first frameare integrally formed. The other part of the second connection portionand the second frameare integrally formed. When the first frameand the second frameare connected and fixed to each other to define the oil collecting groove, the part of the second connection portionis engaged with the other part of the second connection portionto define the oil discharge opening.
