[0037] See also Figure 1 According to some embodiments of the present application, the present application proposes an air conditioner 100, including a housing 10 and a filter assembly 20. The housing 10 is provided with an air inlet 11; the filter assembly 20 is arranged in the housing 10 and corresponds to the position of the air inlet 11.

[0038] In this embodiment, the air conditioner 100 may be an air conditioner, a heat pump, a multi-split unit, or other equipment for cooling or heating.

[0039] Exemplarily, the air conditioner 100 is an air conditioner having a cabinet having a casing 10 , and an air inlet 11 is opened at one side of the bottom of the casing 10 .

[0040] In some embodiments, a heat exchanger (not shown) is further disposed in the housing 10 and is located above the filter assembly 20; wherein the unfolded area of ​​the filter 22 is not less than the windward area of ​​the heat exchanger.

[0041] In this embodiment, since the expanded area of ​​the filter 22 is not less than the area of ​​the heat exchanger, the air volume flowing through the filter 22 per unit time is not less than the air volume flowing through the heat exchanger, which helps to improve the heat exchange efficiency between the air and the heat exchanger.

[0042] By setting a heat exchanger in the casing 10, and setting the filter 22 below the heat exchanger, and making the position of the heat exchanger correspond to the position of the air inlet 11, the air flowing to the air inlet 11 can enter the casing 10 after passing through the filter, and exchange heat with the heat exchanger in the casing 10, so as to improve the heat exchange efficiency of the heat exchanger.

[0043] See also Figures 2 to 4According to some embodiments of the present application, the filter assembly 20 includes a mounting bracket, a filter 22 and at least one connecting member 23. Specifically, the mounting bracket includes a first bracket 211 and a second bracket 212 arranged at intervals along a first direction, a first card slot 2111 is provided on a side of the first bracket 211 facing the second bracket 212, and a second card slot 2121 is provided on a side of the second bracket 212 facing the first bracket 211; the filter is respectively embedded in the first card slot 2111 and the second card slot 2121 on both sides along the first direction, and the filter includes at least two sub-filters 221 arranged side by side; the connecting member 23 is provided on one side of the filter along the second direction, for connecting two adjacent sub-filters 221, wherein the second direction is perpendicular to the first direction.

[0044] In this embodiment, one side of the filter 22 along the first direction is respectively connected to the first slot 2111 and the second slot 2121, the connecting member 23 is located on one side of the filter 22 along the second direction, and the bottom of the filter 22 is located on the other side along the second direction and is used to abut against the bottom surface of the casing 10.

[0045] The filter 22 can not only be used to filter dust in the air, but also can play a role in disinfection and sterilization to improve the cleanliness of the air.

[0046] At least two sub-filter screens 221 are arranged side by side, which means that the planes where the at least two sub-filter screens 221 are located are located in the same plane, and two adjacent sub-filter screens 221 are close to or in contact with each other.

[0047] Exemplarily, the connecting member 23 and two adjacent sub-filter screens 221 may be snap-connected or screw-connected.

[0048] The first bracket 211 and the second bracket 212 are arranged at intervals along the first direction at the air inlet 11 of the air conditioner 100. When installing the filter, one side of the filter 22 along the first direction can be engaged with the first slot 2111 defined by the first bracket 211, and the other side can be engaged with the second slot 2121 defined by the second bracket 212. Along the second direction perpendicular to the first direction, two adjacent sub-filters 221 can be connected by a connector 23, so that the filter can be installed and fixed. When the filter 22 needs to be replaced or removed, the connection between the two adjacent sub-filters 221 and the connector 23 can be released first, and then a filter connected to the first slot 2111 of the first bracket 211 is removed from the first bracket 211, and another filter connected to the second slot 2121 of the second bracket 212 is removed from the second bracket 212, so that the filter can be removed as a whole. The installation and removal are relatively simple, which is convenient for the maintenance and replacement of the filter in the later stage, and the product has fewer parts, which helps to reduce costs.

[0049] It is understandable that when the number of sub-filters 221 is greater than three, if a sub-filter 221 located in the middle needs to be replaced, the filter can be disassembled and replaced by simply releasing the connection relationship of the connecting piece 23 connected to the sub-filter 221.

[0050] See also Figure 2 According to some embodiments of the present application, the first bracket 211 includes a first support body, the first support body is set at an angle with the horizontal plane, and a first card slot 2111 is provided on the side of the first support body facing the second bracket 212; the second bracket 212 includes a second support body, the second support body is set at an angle with the horizontal plane, and a second card slot 2121 is provided on the side of the second support body facing the first bracket 211; wherein the angle between the first support body and the horizontal plane is equal to the angle between the second support body and the horizontal plane.

[0051] In this embodiment, the first support body and the second support body may be connected to the side panels of the housing 10 , or may be connected to the bottom panel of the housing 10 .

[0052] By setting the first support body and the second support body to be set at the same angle with the horizontal plane, when the filter is respectively engaged with the first slot 2111 and the second slot 2121 on both sides along the first direction, the plane where the filter is located can also be set at an angle with the horizontal plane. This not only helps to reduce the space occupied by the filter in the height direction of the casing 10, but also allows the filter to block the air inlet 11, so that as much air as possible from the air inlet 11 can pass through the filter before entering the interior of the casing 10, which helps to further improve the air purification effect.

[0053] In another embodiment, the first bracket 211 also includes a third support body (not shown in the figure), which is connected to the first support body and is set at an angle to the first support body; the second bracket 212 also includes a fourth support body (not shown in the figure), which is connected to the second support body and is set at an angle to the second support body.

[0054] In this embodiment, the third support body of the first bracket 211 can be connected to the side wall or bottom plate of the housing 10, and can be connected to the first support body at an angle, so as to support the first support body, which helps to improve the stability of the support of the first bracket 211. Similarly, the fourth support body of the second bracket 212 can be connected to the other side wall or bottom plate of the housing 10, and can be connected to the second support body at an angle, so as to support the second support body, which helps to improve the stability of the support of the second bracket 212, and further helps to improve the stability of the support connection of the mounting bracket to the filter.

[0055] See also Figure 2According to some embodiments of the present application, the angle between the first support body and the second support body and the horizontal plane is α, 45°≤α≤90°.

[0056] In this embodiment, the angles between the extension directions of the first support body and the second support body and the horizontal plane are both 45°. In this way, the filter is also set at 45° to the horizontal plane, thereby increasing the contact area between the filter and the air at the air inlet 11, thereby helping to improve the purification efficiency of the air at the air inlet 11.

[0057] See also Figures 2 to 4 According to some embodiments of the present application, the filter assembly 20 also includes a support member 24, which is located above the filter. An installation gap 25 is defined between the connecting member 23 and the support member 24, and portions of two adjacent sub-filters 221 on one side along the second direction are crimped into the installation gap 25.

[0058] In this embodiment, illustratively, the support member 24 is disposed in the casing 10 to support components such as a heat exchanger or a water receiving tray.

[0059] Part of the connecting member 23 is arranged at an angle to the supporting member 24, so that an installation gap 25 can be defined between the connecting member 23 and the supporting member 24. In this way, when two adjacent sub-filters 221 are connected, the parts of the two adjacent sub-filters 221 on one side close to each other can be pressed into the installation gap 25 through the connecting member 23, so that the parts of the two adjacent sub-filters 221 along the second direction can be limited in the installation gap 25. The structure and principle are relatively simple and easy to implement.

[0060] See also Figure 3 According to some embodiments of the present application, the connector 23 includes a main body 231 and a crimping portion 232 connected to the main body 231 , the main body 231 is connected to the support member 24 , and an installation gap 25 is defined between the crimping portion 232 and the support member 24 .

[0061] In this embodiment, illustratively, the main body 231 is a connecting plate, and the connecting plate and the support member 24 are detachably connected, for example, the connecting plate and the support member 24 are screwed or snapped together.

[0062] The connecting member 23 is connected to the supporting member 24 via the main body 231, and two adjacent sub-filters 221 are clamped on one side along the second direction via the installation gap 25 formed between the crimping portion 232 and the supporting member 24, so that the adjacent sub-filters 221 can be fixed, and the position of the crimping portion 232 can be fixed after the main body 231 is connected to reduce the risk of the connecting member 23 moving freely relative to the filter, thereby improving the reliability of the connection between adjacent sub-filters 221.

[0063] See also Figure 3 According to some embodiments of the present application, along the first direction, the length of the crimping portion 232 is smaller than the length of the main body portion 231 .

[0064] In this embodiment, after the main body 231 is connected to the water receiving tray, the position of the crimping portion 232 can be fixed, and the crimping portion 232 only needs to clamp two adjacent sub-filters 221 partially on one side along the second direction. By setting the length of the main body 231 along the second direction to be greater than the length of the crimping portion 232, it is not only convenient for the assembly and connection of the main body 231, but also helps to reduce the production cost of the connecting piece 23.

[0065] See also Figure 5 According to some embodiments of the present application, the filter screen is defined by a plurality of folds 2213 , and the plurality of folds 2213 are spaced apart along a first direction and extend along a second direction.

[0066] In this embodiment, by providing a plurality of folds 2213 spaced apart along a first direction on one side of the filter, a plurality of grooves can be formed on the surface of the filter. The plurality of grooves are spaced apart along the first direction, and each groove extends along the second direction of the filter. This allows air to flow along the direction of the grooves when passing through the filter, thereby reducing the resistance of the filter to wind, and helping to further improve the efficiency of air passing through the filter.

[0067] See also Figure 2 According to some embodiments of the present application, the length of the filter along the first direction is greater than the length of the filter along the second direction.

[0068] In this embodiment, it can be understood that the first direction is the length direction of the filter screen, and the second direction is the width direction of the filter screen. Then one side of the width direction of adjacent sub-filter screens 221 is connected by a connector 23, thereby helping to reduce the space occupied by the filter screen in the height direction in the housing 10.

[0069] See also Figure 5 According to some embodiments of the present application, the sub-filter 221 includes a filter body 2211 and a connecting portion 2212 arranged around the outer edge of the filter body 2211. Along the thickness direction of the sub-filter 221, the size of the connecting portion 2212 is larger than the size of the filter body 2211, and the connecting portion 2212 is embedded in the first slot 2111 and the second slot 2121.

[0070] In this embodiment, since the connection portion 2212 located at the edge of the filter body 2211 is used to connect with the mounting bracket and the connecting piece 23, the thickness of the connection portion 2212 is appropriately increased to appropriately increase the stiffness and hardness of the connection portion 2212, thereby helping to improve the stability of the filter when assembled and connected with the mounting bracket and the connecting piece 23.

[0071] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
