When the window air conditioner is installed on the window, its structural size has a positive correlation with the installation difficulty, that is, the larger the size, the higher the installation difficulty. Therefore, the miniaturization design of the window air conditioner is essential for the popularization of the window air conditioner.

As shown in, according to some embodiments of the present disclosure, there is provided a window air conditioner. The window air conditioneris adapted to be installed on a windowwhen the window air conditioneris arranged in an indoor environment. Since the window air conditioneris arranged on the window, the arrangement of the window air conditionerin the indoor environment can be more space-saving, which facilitates the arrangement of the window air conditionerin the indoor environment. The window air conditionercan be arranged on the window, which can provide more reliable service performance, can be applied to the indoor environment to meet the needs of the user, and can improve the comfort of the user using the window air conditioner.

As shown in, in some embodiments, the window air conditionermay include a casing. The casingmay be used to provide an assembly space. The casingallows other structures within the window air conditionerto be arranged within the casing. The casingcan protect other structures, thereby allowing the window air conditionerto have higher service performance and service life during use.

In some embodiments, the window air conditionermay include an indoor heat exchanger. The indoor heat exchangermay be disposed in the casing. The indoor heat exchangercan be used to exchange heat with the indoor airflow to allow the airflow after the heat exchange to act on the indoor environment to improve the user's experience in the indoor environment.

In some embodiments, the window air conditionermay include an indoor fan assembly. The indoor fan assemblymay be disposed in the casing. The indoor fan assemblymay be used to introduce indoor airflow. The indoor fan assemblymay deliver the indoor air to the indoor heat exchangerfor heat exchange and then output the indoor air to the room.

In some embodiments, the window air conditionermay include an outdoor heat exchanger. The outdoor heat exchangermay be disposed in the casing. The outdoor heat exchangermay be used to exchange heat with the outdoor airflow.

In some embodiments, the window air conditionermay include an outdoor fan assembly. The outdoor fan assemblymay be disposed in the casing. The outdoor fan assemblymay be used to drive outdoor airflow into the window air conditioner. The outdoor fan assemblymay deliver outdoor air to the outdoor heat exchangerfor heat exchange and then output the outdoor air to the outdoor.

In some embodiments, the window air conditionermay include a casing, an indoor heat exchanger, an indoor fan assembly, an outdoor heat exchanger, and an outdoor fan assembly. During the structural arrangement of the window air conditioner, the window air conditionermay include a casing, an indoor heat exchanger, an indoor fan assembly, an outdoor heat exchanger, and an outdoor fan assembly.

In some embodiments, the refrigerant may circulate between the indoor heat exchangerand the outdoor heat exchangerduring use of the window air conditioner. The indoor airflow and the outdoor airflow exchange heat with the indoor heat exchangerand the outdoor heat exchanger, respectively, which allows the refrigerant to perform more efficiently during circulation, enhances the operating performance of the window air conditioner, and enables the window air conditionerto better improve the indoor environment.

As shown in, in some embodiments, the casingmay include a base. The indoor heat exchanger, the indoor fan assembly, the outdoor heat exchanger, and the outdoor fan assemblymay be disposed on the base, and the basemay be used to provide a support function. The indoor heat exchanger, the indoor fan assembly, the outdoor heat exchanger, and the outdoor fan assemblycan be constructed on the baseto make the arrangement of the indoor heat exchanger, the indoor fan assembly, the outdoor heat exchanger, and the outdoor fan assemblyin the casingmore reliable.

As shown in, in some embodiments, the casingmay include an indoor housing. The indoor housingmay be disposed on the base. The indoor housingmay house the indoor heat exchangerand the indoor fan assembly. The indoor heat exchangerand the indoor fan assemblymay correspondingly be constructed between the indoor housingand the base.

As shown in, in some embodiments, the casingmay include an outdoor housing. The outdoor housingmay be disposed on the base. The outdoor housingmay house the outdoor heat exchangerand the outdoor fan assembly. The outdoor housingmay be connected to the indoor housing. The outdoor heat exchangerand the outdoor fan assemblymay correspondingly be constructed between the outdoor housingand the base.

In some embodiments, during the construction process of the casing, the base, the indoor housing, and the outdoor housingcan be separately constructed, which can simplify the construction process, enable the structure of the casingto exhibit superior performance, protect other structures in the window air conditioner, and improve the service life of the window air conditioner.

As shown in, in some embodiments, the top of the indoor housingmay be lower than the top of the outdoor housing. During the arrangement of the indoor housingand the outdoor housing, the indoor housingmay be constructed on the inside of the window, and the outdoor housingmay be constructed on the outside of the windowso that the windowis adapted to be snapped on the casing. Since the top of the indoor housingis lower than the top of the outdoor housing, the structure of the indoor housingcan be made more compact, thereby facilitating the arrangement of the window air conditioneron the window. Since the top of the outdoor housingis higher than the top of the indoor housing, the air inlet of the outdoor housingcan have a larger air inlet area to introduce outdoor airflow, which allows the outdoor heat exchangerto achieve higher heat exchange performance during operation, thereby enhancing the overall performance of the window air conditioner.

In some embodiments, an avoiding grooverecessed towards the base may be formed between the indoor housingand the outdoor housing. The avoiding groovemay be used to avoid the lower edge of the window. By providing a recessed avoiding groovebetween the indoor housingand the outdoor housing, the avoiding groovecan be arranged opposite to the window, enabling the windowto be snapped on the avoiding groove, thereby making the arrangement of the window air conditioneron the windowmore reliable.

With the window air conditioneraccording to some embodiments of the present disclosure, since the top of the indoor housingis lower than the top of the outdoor housing, the structural size of the indoor housingcan be made smaller, and the arrangement of the indoor heat exchangerand the indoor fan assemblyin the indoor housingcan be more compact. At the same time, since the top of the outdoor housingis higher than the top of the indoor housing, the outdoor housingcan have a larger air inlet area in the structural design, and the use performance of the outdoor heat exchangercan be improved, so that the use performance of the window air conditionercan be higher to meet the needs of users.

In some embodiments, the vertical maximum distance from the top of the indoor housingto the basemay be h1, the vertical maximum distance from the top of the outdoor housingto the basemay be h2, where h1 and h2 may satisfy the relation: h1≥0.5 h2. The relative dimensional relationship between the indoor housingand the outdoor housingshould not be too small. If the ratio between the vertical height of the indoor housingand the vertical height of the outdoor housingis too small, the structure of the indoor housingwill be too small, thereby affecting the arrangement of the indoor heat exchangerand the indoor fan assemblyin the indoor housing, resulting in relatively low use performance of the indoor heat exchangerand the indoor fan assembly, thereby affecting the use performance of the window air conditioner.

In some embodiments, the vertical maximum distance from the top of the indoor housingto the basemay be h1, the vertical maximum distance from the top of the outdoor housingto the basemay be h2, where h1 and h2 may satisfy the relation: h1≤0.75 h2. The relative dimensional relationship between the indoor housingand the outdoor housingshould not be too large. If the ratio between the vertical height of the indoor housingand the vertical height of the outdoor housingis too large, the air inlet area on the outdoor housingwill be insufficient, and the use performance of the outdoor heat exchangerwill not be better improved, thereby affecting the use performance of the window air conditioner.

In some embodiments, the vertical maximum distance from the top of the indoor housingto the basemay be h1, and the vertical maximum distance from the top of the outdoor housingto the basemay be h2, where h1 and h2 may satisfy the relation: 0.5 h2≤h1≤0.75 h2. The ratio between the vertical height of the indoor housingand the vertical height of the outdoor housingis set between 0.5 and 0.75, which balances the structural compactness of the indoor housingwith the relatively higher performance of the outdoor housing, making the installation process of the window air conditioneron the windowsimpler, the structure more reliable, and enhancing its performance to improve the indoor environment.

As shown in, in some embodiments, the indoor housingincludes an indoor top plate. The indoor top platemay be located in a top region of the indoor housing.

In some embodiments, the indoor top platemay include a first top plate portion. The first top plate portionmay be constructed on top of the indoor housing. The vertical height of the indoor housingmay be a relative distance between the first top plate portionand the base.

In some embodiments, the indoor top platemay include a third top plate portion. The first top plate portionmay be higher than the third top plate portion. The third top plate portionmay be located on a side of the first top plate portionclose to the outdoor housing. The third top plate portionmay be used for connection with the outdoor housing.

In some embodiments, the indoor top platemay include a second top plate portion. The second top plate portionmay be connected between the first top plate portionand the third top plate portion. The second top plate portionmay be provided to be bent relative to the first top plate portionand the third top plate portion. The second top plate portionis connected to the first top plate portionand the third top plate portionin a relatively bent manner, allowing the third top plate portionto be constructed on the lower side of the first top plate portion, allowing the third top plate portionto be recessed under the second top plate portion, and an avoiding groovethat is configured to connect to the windowis formed. For example, the second top plate portion, the third top plate portion, and the outdoor housingmay be used to form the avoiding groovetogether, which not only makes the structural setting of the avoiding groovemore reliable, but also enables the window air conditionerto be snapped on the windowstably, and allows the window air conditionerto apply the usage performance to the indoor environment to improve the indoor environment.

The overlap platecan improve the structural strength of the outdoor front plate. The lap plateallows the avoiding grooveformed among the outdoor front plate, the second top plate portionand the third top plate portionto have higher structural strength and performance.

In some embodiments, the lap platemay be disposed outside the third top plate portion. The lap platemay be overlapped above the top surface of the third top plate portion. This arrangement allows the lap plateto protect the third top plate portion, ensuring reliable use of the third top plate portion.

In some embodiments, at least a portion of the lap plateand the third top plate portionmay overlap. In this way, the lap platecan be adapted to correspondingly improve the structural performance of the third top plate portion, and the third top plate portioncan have higher structural strength, so that the use performance of the avoiding groovecan be correspondingly improved, and the window air conditionercan be snapped on the windowreliably.

As shown in, in some embodiments, the indoor housingmay include indoor side plates. The indoor side platesmay be connected to both sides of the indoor top plate. For example, two indoor side platesmay be provided. The two indoor side platesmay be connected to two sides of the indoor top plate, respectively.
