The fixed end is connected to the insertion column, the free end extends toward a direction close to the support foot, and the extension arm is engaged with the insertion groove.

Hereinafter, some embodiments of the present disclosure will be clearly and completely described with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, but not all embodiments. Based on the embodiments provided by the present disclosure, all other embodiments obtained by those ordinarily skilled in the art fall within the scope of protection of the present disclosure.

In related air conditioners, to improve the support performance of support feet for a main unit, a plurality of support feet are arranged to support the main unit. However, the complex connection structure between the support feet and the main unit leads to inconvenient mounting for the user and time consuming. Furthermore, the arrangement of support feet affects the aesthetic appeal of mounting of the main unit, reducing the usage experience of the user.

To solve the above problem, as shown in, an air conditioner provided by some embodiments of the present disclosure can include a housing. The housingcan be configured as a shell outside the air conditioner. The interior of the housingcan be used for providing a mounting space.

As shown in, in some embodiments, the housingmay be of a cuboid hollow structure. The length direction of the housingcan be set along the height direction, so that the air conditioner is disposed upright at the usage site, thereby increasing the height of the air conditioner and reducing the space occupied by the air conditioner.

It should be noted that in other embodiments, the appearance and shape of the housingcan be designed according to requirements, which is not limited herein.

As shown in, in some embodiments, the air conditioner can include a refrigerant circuit. The refrigerant circuit can include a compressor, an outdoor heat exchanger, and an indoor heat exchangerconnected end to end. A refrigerant flows circularly in the refrigerant circuit formed by the compressor, the outdoor heat exchanger, and the indoor heat exchanger. During the refrigerant cycle, the outdoor heat exchangerand the indoor heat exchangermay serve as a condenser and an evaporator, respectively, so that the refrigerant is evaporated in the evaporator to absorb heat and is condensed in the condenser to release heat, thereby enabling a refrigerating cycle or a heating cycle of the air conditioner to be executed.

Specifically, during the refrigerating cycle, the outdoor heat exchangermay serve as the condenser, and the indoor heat exchangermay serve as the evaporator. During the heating cycle, the outdoor heat exchangermay serve as the evaporator, and the indoor heat exchangermay serve as the condenser.

It should be noted that both the refrigerating cycle and the heating cycle include a series of processes involving compression, condensation, expansion, and evaporation, and supply the refrigerant to air that has been conditioned and undergone heat exchange.

The compressoris used for compressing a refrigerant gas and discharging the compressed refrigerant gas. The discharged refrigerant gas flows into the condenser.

The condenser condenses the compressed refrigerant into a liquid phase, and heat is released to the ambient environment through the condensing process.

The evaporator evaporates the expanded refrigerant and makes the refrigerant gas in a low-temperature and low-pressure state return to the compressor. The evaporator can achieve the refrigerating effect by exchanging heat with the ambient environment by means of the latent heat of evaporation from the refrigerant.

During the whole cycle, the air conditioner can regulate the temperature of the indoor space, thereby improving the comfort level within the indoor space, and improving the usage experience of the user.

As shown in, in some embodiments, the air conditioner can include an outdoor fan assembly. The outdoor fan assemblycan be disposed opposite to the outdoor heat exchanger. The outdoor fan assemblycan be used for introducing outdoor air into the housingto exchange heat with the outdoor heat exchangerto form a heat exchange air flow.

For example, during the refrigerating cycle, the outdoor heat exchangerserves as the condenser, and the outdoor fan assemblycan draw external air and blow it to the outdoor heat exchangerto dissipate heat from the outdoor heat exchangerso as to decrease the temperature of the outdoor heat exchanger. During the heating cycle, the outdoor heat exchangerserves as the evaporator, and the outdoor fan assemblycan draw external air and blow it to the outdoor heat exchangerto heat the outdoor heat exchangerso as to increase the temperature of the outdoor heat exchanger.

As shown in, in some embodiments, the air conditioner can include an indoor fan assembly. The indoor fan assemblycan be disposed opposite to the indoor heat exchanger. The indoor fan assemblycan be used for introducing indoor air into the housingto exchange heat with the indoor heat exchangerto form a heat exchange air flow.

For example, during the refrigerating cycle, the indoor heat exchangerserves as the evaporator, and the indoor fan assemblycan draw indoor air outside the housingand blow it to the indoor heat exchangerto exchange heat from the indoor heat exchangerso as to decrease the temperature of air flowing through the indoor heat exchanger, and blow the temperature-decreased air back to the indoor space so as to decrease the indoor air temperature.

For another example, during the heating cycle, the indoor heat exchangerserves as the condenser, and the outdoor fan assemblycan draw indoor air outside the housingand blow it to the indoor heat exchangerto exchange heat from the indoor heat exchangerso as to increase the temperature of air flowing through the indoor heat exchanger, and blow the temperature-increased air back to the indoor space so as to increase the indoor air temperature.

As shown in, in some embodiments, the compressor, the outdoor heat exchanger, the outdoor fan assembly, the indoor heat exchanger, and the indoor fan assemblycan be respectively disposed within an accommodating spaceinside the housing. In this way, the housingcan provide a covering protection effect and can prevent structural damage caused by external foreign object incursion or external force impact, thereby improving the structural reliability of the air conditioner and ensuring that the air conditioner can work normally.

As shown in, in some embodiments, the accommodating spaceinside the housingcan include three layers of sub-spaces. The three layers of sub-spaces are respectively a first sub-space, a second sub-space, and a third sub-spacearranged in sequence from bottom to top. The compressorcan be disposed in the first sub-space. The outdoor heat exchangerand the outdoor fan assemblycan be disposed in the second sub-space. The indoor heat exchangerand the indoor fan assemblycan be disposed in the third sub-space. Thus, through the three layers of sub-spaces in sequence from bottom to top, the components such as the compressor, the outdoor heat exchanger, the outdoor fan assembly, the indoor heat exchanger, and the indoor fan assemblycan be arranged in a scattered manner at different height positions inside the housing, which is beneficial to improving the overall height of the air conditioner, reducing the width and thickness dimensions of the air conditioner, and reducing the space of the usage site occupied by the air conditioner.

As shown inand, in some embodiments, the housingcan include a chassis. The chassiscan be disposed at the bottom of the housing. The accommodating spaceof the housingcan be formed above the chassis. The accommodating spacecan serve as a mounting space for other components of the air conditioner. The chassiscan be used for supporting other components of the air conditioner.

The chassis is shown inand. In some embodiments, the housingcan include support feet. The support feetcan be disposed on the chassis. The support feetcan be used for increasing the contact area between the bottom of the housingand the ground, thereby improving the reliability of supporting the air conditioner by the chassis, and improving the stability of the air conditioner.

As shown inand, in some embodiments, a plurality of support feetmay be disposed. The plurality of support feetare supported on the chassis, enhancing the support stability and reliability on the chassis.

For example, as shown in, four support feetmay be disposed. The four support feetcan be spliced end to end to form a polygonal annular structure. It should be noted that in other embodiments, the number of the support feetmay be 3, 5, etc., which is not limited herein.

As shown inand, in other embodiments, two opposite ends of the plurality of support feetcan be sequentially spliced end to end and continuously arranged circumferentially around the periphery of the chassis. It should be noted that the plurality of support feetcontinuously arranged around the periphery of the chassiscan form a closed annular structure.

Specifically, one end of two opposite ends of each support footcan be spliced with one adjacent support foot, and the other end of two opposite ends of the support footcan be spliced with another adjacent support foot, such that the two opposite ends of the plurality of support feetcan be sequentially spliced end to end to form a structure encircling and circumferentially arranged around the periphery of the chassis. By means of splicing the support feetmutually into an encircling structure, compared with a single independent support footin existing structures, due to each support foothaving independent force reception being prone to shaking from uneven ground or external force action, in this technical solution the end-to-end spliced support feetintegrally present a support ring structure, not only enabling each support footto achieve uniform force distribution but also enhancing overall support strength, thereby preventing the stability from being affected due to the looseness of a single support foot.

As shown in,, and, in some embodiments, the two opposite ends of each support footcan be a first endand a second end, respectively. A clamping groovecan be concavely formed in the first endof the support foot. A positioning portioncan be convexly disposed in the second endof the support foot. The positioning portioncan be in fit with the clamping groove.

As shown in, the positioning portionof the support footcan be inserted into the clamping grooveof an adjacent support footin an aligned manner, such that the second endof the support footis spliced with the first endof the adjacent support foot. The clamping grooveof the support footcan be inserted into the positioning portionof another adjacent support footin an aligned manner, such that the first endof the support footis spliced with the second endof the another adjacent support foot.

Specifically, the first endand the second endof the support footare connected to a support foot, respectively. By inserting the positioning portionof the support footinto the clamping grooveof an adjacent support foot, the positioning portionis clamped in the clamping groove, such that the second endof the support footis spliced with the first endof the adjacent support foot. By means of the corresponding clamped connection between the clamping grooveof the support footand the positioning portionof another corresponding adjacent support foot, the first endof the support footis spliced with the second endof the another adjacent support foot. Thus, by inserting the positioning portionof the adjacent support footinto the corresponding clamping groove, the clamped splicing manner between the support feetdoes not need to use tools for mounting and also reduces the mounting difficulty of the support feet, achieving simplification of the support structure of the chassis, and reducing the operation difficulty for the user. Further, after splicing is completed, the plurality of support feetcan form an encircling support structure, enabling each support footto achieve uniform force distribution, thereby effectively improving the support strength of the support feet. Furthermore, the structure of each support footis identical, such that the plurality of support feetcan be flexibly spliced and combined with each other.

As shown inand, in some embodiments, the first endof the support footcan be provided with a first clamping portion. The first clamping portioncan be convexly disposed from the sidewall of the clamping groovetoward the interior of the clamping groove. A first positioning groovecan be concavely formed in the positioning portion. The first positioning groovecan be formed corresponding to the first clamping portion.

When the positioning portionis inserted into the clamping groovein place, the first clamping portionis embedded into the first positioning grooveto fix the positioning portionwithin the clamping groovein a clamped manner.

Specifically, the first endof the support footnot only is provided with the clamping groove, but also has the first clamping portionconvexly disposed toward the interior of the clamping groovethrough the sidewall of the clamping groove. Correspondingly, the positioning portionon the second endof the support footnot only is used for cooperating with the clamping groove, but also has the first positioning grooveconcave in the surface, and the first positioning grooveis formed corresponding to the first clamping portion. Thus, when the positioning portionis inserted into the clamping groove, the first clamping portioncan be accurately embedded into the first positioning groove, such that the positioning portionis securely clamped into the clamping groove.

In the embodiments of the present disclosure, through further cooperative clamped-connection of the first clamping portionwith the first positioning groovebetween the positioning portionand the clamping groove, the splicing structure between the adjacent support feetobtains further reinforcement, improving the stability of the splicing structure between the plurality of support feet, facilitating that the support feetbecome less prone to loosening or detachment during prolonged usage. Regarding mounting efficiency, during insertion of the positioning portioninto the clamping grooveby the user, as the positioning portionmoves within the clamping grooveuntil the first clamping portionis clamped into the first positioning groove, the adjacent support feetcan be fixed, achieving rapid splicing between the support feet, significantly simplifying mounting steps, and improving mounting efficiency.

As shown inand, in some embodiments, the shape and dimensions of the first clamping portioncan fit those of the first positioning groove. For example, the first clamping portionmay be configured as a triangular structure; correspondingly, the first positioning groovemay be configured as a concave triangular groove.

In some other embodiments, the first clamping portionmay also be convexly disposed on the positioning portion. The first positioning groovemay also be concavely formed from the sidewall of the clamping groove. The first positioning groovecan be formed corresponding to the first clamping portion, and the first clamping portioncan be clamped into the groove.

As shown inand, in some embodiments, the surface of the first clamping portioncan form a first guiding inclined surface (not shown in the figures). The first guiding inclined surface can tilt toward the first positioning groove. The first guiding inclined surface can be used for guiding cooperative clamped-connection of the first clamping portionwith the first positioning groove, or guiding detachment of the first clamping portionfrom the first positioning groove. Specifically, the first guiding inclined surface can reduce the frictional resistance during the clamped connection between the first clamping portionand the first positioning groove, thereby improving the smoothness of the support feetduring splicing, and further improving mounting efficiency.

As shown in, in some embodiments, the support footis detachably connected to the chassis. A detachable connection structure may be between the support footand the chassis. In this way, the user can selectively use the support feetto support the chassis. For example, rollersare disposed on the chassis, and the user moves the air conditioner to the usage position and can fix the position of the air conditioner by mounting the support feet. When the user needs to move the air conditioner, the support feetcan be detached from the chassis, thereby preventing the friction force formed between the support feetand the ground and increasing the movement difficulty.

As shown in, in some embodiments, the support footand the chassismay be connected through an insertion structure. The insertion structure between the support footand the chassiscan reduce the difficulty for the user to mount and detach the support foot, improving the usage convenience for the user.

As shown in, in some embodiments, a side of the chassisfacing the support footcan be provided with an insertion portion. The insertion portion can be used for being connected to the support foot, such that the support footis connected to the peripheral side of the chassis. Next take the insertion portion as an insertion groovefor example, to describe a connection structure between the insertion portion and the chassisin detail.

As shown inand, in some embodiments, a side of the support footfacing the chassiscan be provided with an insertion column. The insertion columncan extend toward the chassis. A side of the chassisfacing the support footcan be provided with an insertion groove. The insertion groovecan extend toward a side away from the support foot. The insertion columncan be disposed opposite to the insertion groove.

The insertion columnextends along the support foottoward the chassis, such that an accurate alignment fixed structure can be formed between the support footand the chassis. In this way, the support footcan be directly inserted in an aligned manner and connected to the chassis, reducing the mounting difficulty between the support footand the chassis, and effectively improving mounting efficiency. Furthermore, the support footis directly inserted into the insertion grooveof the chassisthrough the insertion column, such that a connection fixed structure is provided between the support footand the chassis, further preventing the support footfrom shifting or detachment due to vibration or external force action. Meanwhile, the insertion structure makes force reception of the support feetmore uniform, improving the durability of the support feet.

As shown inand, in some embodiments, a plurality of insertion groovesmay be formed. The plurality of insertion groovesare formed corresponding to the insertion columnsof the plurality of support feet. The insertion columnof each support footis inserted into the corresponding insertion groovein an aligned manner.

Specifically, a plurality of insertion groovescan be formed corresponding to the support feet, and the plurality of support feetcan be inserted into the insertion groovesthrough the insertion columns, respectively, such that the plurality of support feetare respectively connected to the chassis.

As shown inand, in some embodiments, a side of the support footfacing the chassismay be provided with a plurality of insertion columns.

It should be noted that due to relying solely on a single insertion columnto connect the support footand the chassis, the connection is prone to loosening from external force or vibration. By arranging the plurality of insertion columnson the support foot, correspondingly, a corresponding number of insertion groovesare formed in the chassis, such that the connection points between the support footand the chassiscan be increased. The plurality of insertion columnsof the same support footare inserted into the corresponding insertion groovesin the chassis, respectively, such that a more stable multi-point support structure is formed, effectively preventing each support footfrom loosening or shifting from the chassis.
