Description

Technical Field

[0001] The present invention relates to the technical field of air conditioners, and in particular to an air conditioner indoor unit. Background Art

[0002] With the advancement of science and technology, the number of air conditioners in use is increasing, and the demand for them has become indispensable. Air conditioner indoor units are typically wall-mounted. If this is done, the entire housing of the unit is exposed indoors, compromising the consistency and aesthetics of the unit, other appliances, and cabinets within the room. Therefore, an alternative installation method is to embed the unit within a cabinet.

[0003] Currently, in the prior art, air conditioners are usually installed in cabinets with openable and closable doors. When the air conditioner is on, the user can open the door, and when the air conditioner is off, the user can close the door. However, the user has to open or close the door manually each time, which brings great inconvenience to the user and reduces the user experience. Summary of the Invention

[0004] An object of the present invention is to provide an air conditioner indoor unit that can solve at least one of the above-mentioned defects in the prior art.

[0005] A further object of the present invention is to enable the cabinet door to be opened and closed without the user having to do it himself after the air conditioner indoor unit is embedded, so as to improve the user experience.

[0065] When an air conditioner is operating in cooling mode, a large amount of condensed water adheres to its indoor heat exchanger. As the amount of condensed water adheres increases, the condensed water will flow down from the indoor heat exchanger. Currently, in the prior art, a water receiving trough is installed in the indoor unit of the air conditioner to receive the condensed water flowing down from the indoor heat exchanger. Furthermore, a drain pipe is installed in the connection pipe between the outdoor and indoor units of the air conditioner. One end of the drain pipe is connected to the water receiving trough, and the other end of the drain pipe extends to the outdoors through a connection hole in the wall. When the air conditioner is operating in cooling mode, the condensed water generated on the indoor heat exchanger flows through the water receiving trough and drain pipe to the outdoors, preventing the condensed water from flowing into the indoor space and dirtying the indoor floor, thereby ensuring a good user experience when using the air conditioner. However, since air conditioners rely on gravity for drainage, ensuring condensate flows smoothly outdoors requires high requirements for the height of the connection holes and the layout of the connection pipes. For example, the connection pipes must be installed below the bottom of the air conditioner's indoor unit, and the connection holes must also be located below the bottom of the unit. If the indoor unit is not installed according to these requirements, poor drainage can lead to water accumulation inside the room, making the air conditioner installation more difficult. Furthermore, some existing embedded air conditioning solutions require the indoor unit to be installed in an enclosed space such as a cabinet. The connection pipes with drain pipes cannot be directly installed through pre-recorded holes in the wall like conventional wall-mounted units. A certain amount of expansion is often required to ensure easy installation and maintenance. Because embedded air conditioners are designed for aesthetics, the connection pipes with this expansion are often placed inside the cabinet. However, due to limited space inside the cabinet, the connection pipes with this expansion may be placed higher than the bottom of the indoor unit, resulting in poor condensate drainage and water accumulation on the floor.

[0066] Reference Figure 1 、 Figure 2 and Figure 3 In this embodiment, the air conditioner indoor unit 100 includes a housing 110 , an indoor heat exchanger 120 , a drainage pump 210 and a water pipe 220 . The shell 110 includes a base 111, and a water receiving trough 1111 is provided on the front side of the base 111; the indoor heat exchanger 120 is arranged on the base 111, and the water receiving trough 1111 is located below the indoor heat exchanger 120, and the water receiving trough 1111 is used to receive the water flowing down from the indoor heat exchanger 120; the water inlet of the drainage pump 210 is connected to the water receiving trough 1111; one end of the water pipe 220 is connected to the water outlet of the drainage pump 210, and the other end of the water pipe 220 is used to connect to the drainage pipe extending to the outdoor space, the water pipe 220 includes a water supply pipe section 221 with the highest horizontal height, and the water supply pipe section 221 is higher than the part with the lowest horizontal height of the water receiving trough 1111, and the drainage pump 210 is used to transport the water in the water receiving trough 1111 to at least the water supply pipe section 221.

[0067] Since the air-conditioning indoor unit 100 of this embodiment is additionally provided with a drainage pipe and a drainage pump 210, and the water supply pipe section 221 with the highest horizontal height of the drainage pipe is set to be higher than the part with the lowest horizontal height of the water receiving tank, and the drainage pump 210 transports the water in the water receiving tank 1111 to at least the water supply pipe section 221. That is, the condensed water in the water receiving tank 1111 to be discharged outdoors will be raised, and the raised condensed water will then flow out to the outdoors by gravity. Therefore, when the air conditioner indoor unit 100 is installed, the connection hole can be opened on the wall within a height range higher than the bottom of the air conditioner indoor unit and lower than the horizontal height of the water supply pipe section 221; and the connection pipe can be arranged within a height range higher than the bottom of the air conditioner indoor unit 100 and lower than the horizontal height of the water supply pipe section 221; and when the air conditioner indoor unit 100 is selected to be embedded and a certain amount of expansion and contraction of the connection pipe is reserved, the connection pipe can also be arranged within a height range higher than the bottom of the air conditioner indoor unit 100 and lower than the horizontal height of the water supply pipe section 221, and the condensed water will not be drained smoothly and the indoor floor will not be flooded. Therefore, this embodiment can reduce the difficulty of installing the air conditioner and ensure the flow field of draining condensed water when the air conditioner indoor unit has a certain amount of expansion and contraction of the connection pipe.

[0068] Reference Figure 2 and Figure 5 In this embodiment, the water supply pipe section 221 is the highest part at a level higher than the water receiving tank 1111 , and the water supply pipe section 221 is arranged close to the top of the base 111 .

[0069] It can be understood that the water supply section can be set as high as possible. As a specific embodiment, the water supply pipe section 221 can be set near the top of the base 111 to a position higher than the highest part of the water receiving tank 1111, so as to greatly reduce the difficulty of installing the air conditioner, and further ensure the flow field of the condensed water when the air conditioner indoor unit has a certain amount of expansion and contraction of the online pipe reserved (for example, when the air conditioner indoor unit 100 is embedded).

[0070] Reference Figure 2 and Figure 3 In this embodiment, a volute chamber 1112 is provided on the front side of the base 111. This chamber is used to house the indoor fan 130 of the air conditioner indoor unit 100. Furthermore, the water receiving tank 1111 includes a first water tank 1111a and a second water tank 1111b connected to the first water tank 1111a. The first water tank 1111a is located behind the volute chamber 1112, while the second water tank 1111b is located in front of the volute chamber 1112. The second water tank 1111b is lower than the first water tank 1111a. Consequently, the water receiving tank 1111 can fully receive condensed water from the indoor heat exchanger 120 and drain the water from the water receiving tank 1111.

[0071] Reference Figure 2 、 Figure 3 and Figure 5 In this embodiment, the water supply pipe section 221 is higher than the top of the first water tank 1111a.

[0072] It should be noted that the water supply section can be set as high as possible. As a more specific embodiment, the water supply pipe section 221 can be set near the top of the base 111 to a position higher than the top of the first water tank 1111a, so as to greatly reduce the difficulty of installing the air conditioner, and further ensure that when the air conditioner indoor unit has a certain amount of expansion and contraction of the online pipe reserved (for example, when the air conditioner indoor unit 100 is embedded), the flow field of the condensed water can be discharged.

[0073] Reference Figure 3 、 Figure 4 and Figure 5 In this embodiment, the water supply pipe 220 includes an extension section 222 and a water supply section 223, one end of the extension section 222 is connected to the water outlet of the drainage pump 210, and the other end of the extension section 222 extends vertically upward and is connected to the first end of the water supply section 223, the second end of the water supply section 223 extends horizontally toward the outside of the base 111, and the second end of the water supply section 223 is used to connect to the drainage pipe; and the water supply pipe section 221 includes the water supply section 223 and its connection with the extension section 222.

[0074] It can be understood that the extension section 222 can be set so that the water pipe 220 has a water supply pipe section 221 as high as possible and occupies a very small space in the shell 110, and the second end of the water supply section 223 can be extended horizontally toward the outside of the base 111 to facilitate communication with the drain pipe.

[0075] In a modified embodiment, the water pipe 220 is bent and coiled, the bent and coiled water pipe 220 is arranged in a vertical direction, and the end of the water pipe 220 connected to the drain pipe is arranged toward the outside of the base 111 .

[0076] It should be understood that by bending and coiling the water pipe 220 and arranging the bent and coiled water pipe 220 in a vertical direction, the water pipe 220 has a taller water supply section 221. Furthermore, the end of the water pipe 220 connected to the drain pipe can be positioned at the location of the original housing 110 where the drain pipe was located, eliminating the need to re-mold the housing 110 and reducing the production cost of the air conditioner indoor unit 100 of this modified embodiment. Furthermore, by arranging the end of the water pipe 220 connected to the drain pipe toward the outside of the base 111, communication with the drain pipe is facilitated.

[0077] Reference Figure 3 、 Figure 4 and Figure 5In this embodiment, a fixing plate 1113 is provided on the base 111 near its bottom end, and a fixing hole is opened on the fixing plate 1113 corresponding to the position of the water pipe 220. The water pipe 220 is passed through the fixing hole to ensure the stability of the water pipe 220.

[0078] Furthermore, in the prior art, the internal structure of the air conditioner indoor unit 100 is compact, especially in the front of the base 111, which provides extremely high space utilization. If the drain pump 210 were to be placed in the second water tank 1111b or in the front of the base 111, the base 111 would need to be re-molded, increasing the production cost of the air conditioner indoor unit 100. Furthermore, the water storage space in the water tank 1111 is relatively small, and the drain pump 210 would frequently start and stop, significantly reducing its service life.

[0079] Furthermore, the position where the fixing plate 1113 fixes the water pipe 220 may be the extension section 222 .

[0080] Reference Figure 3 and Figure 5 In this embodiment, a placement cavity 1114 is provided behind the base 111; and the air conditioner indoor unit 100 includes a water receiving device 230, which is provided in the placement cavity 1114. The water receiving device 230 is provided with a water receiving space 231 connected to the water receiving tank 1111. The water receiving device 230 is used to store the water in the water receiving tank 1111; and the drainage pump 210 is provided in the water receiving space 231.

[0081] It is understood that the existing wall-mounted air conditioner indoor unit 100 has an unused space (receiving cavity 1114) formed behind the base 111. Therefore, by adding a water receiving device 230, the space for storing condensed water in the air conditioner indoor unit 100 can be increased, thereby reducing the number of starts and stops of the drain pump 210 and ensuring the service life of the drain pump 210. In addition, by arranging the water receiving device 230 within the receiving cavity 1114 and arranging the drain pump 210 within the water receiving space 231, the utilization rate of the internal space of the housing 110 is improved, and the base 111 does not need to be re-molded, thereby effectively controlling the production cost of the air conditioner indoor unit 100.

[0082] Reference Figure 2 、 Figure 3 、 Figure 5 and Figure 6 In this embodiment, the water receiving space 231 is lower than the water receiving tank 1111. Furthermore, the air conditioner indoor unit 100 further includes a drainage pipe 240. A first end of the drainage pipe 240 is connected to the water receiving space 231 downward and rearward, and a second end of the drainage pipe 240 is connected to the lowest portion of the water receiving tank 1111.

[0083] It should be noted that the level of the drainage pipe 240 and the water receiving space 231 is lower than the level of the water receiving tank 1111. Such an arrangement allows the condensed water in the water receiving tank 1111 to flow into the water receiving device 230 by its own gravity without the need for additional power, and be further discharged smoothly.

[0084] Furthermore, the drainage pipe 240 may include a first pipe body 241 communicating with the lowest portion of the water receiving tank 1111 and a second pipe body 242 communicating with the water receiving space 231, and the first pipe body 241 and the second pipe body 242 are connected. This facilitates installation and removal of the water receiving device 230 from the base 111 (and / or the water receiving tank 1111).

[0085] In a modified embodiment, a water pump can be added, for example, the water inlet of the water pump is connected to the water receiving tank 1111 (through a pipe), and the water outlet of the water pump is connected to the water receiving space 231 (through a pipe), so that the condensed water in the water tank can be discharged into the water receiving device 230.

[0086] Reference Figure 2 and Figure 5 In this embodiment, when the water receiving tank 1111 includes the first water tank 1111a and the second water tank 1111b in the above embodiment, the horizontal height of the second water tank 1111b is higher than the horizontal height of the water receiving space 231; and the second end of the drainage pipe 240 is connected to the part with the lowest horizontal height of the second water tank 1111b, so as to realize the setting that the horizontal height of the above-mentioned water receiving space 231 is lower than the horizontal height of the water receiving tank 1111.

[0087] Reference Figure 3 and Figure 5 In this embodiment, the number of drainage pipes 240 is set to be multiple, and the multiple drainage pipes 240 are distributed at the left and right ends of the base 111 and the left and right ends of the water receiving device 230 to ensure the flow field of the condensed water in the water receiving tank 1111 to flow into the water receiving device 230.

[0088] Reference Figure 3 and Figure 5 In this embodiment, the water receiving device 230 is a water receiving tray, and the water receiving space 231 is a trough body with an upward opening on the water receiving tray. This ensures that the water receiving device 230 can store condensed water while minimizing the production cost of the air conditioner indoor unit 100.

[0089] In a modified embodiment, the water receiving device 230 is a water receiving box, and the water receiving space 231 is a cavity within the water receiving box. This ensures that the water receiving device 230 can store condensed water while preventing dust and other debris from entering the water receiving space 231, thereby preventing clogging of the water pump and ensuring the service life of the water pump. Furthermore, if the condensed water in the water receiving space 231 does not reach the preset drainage height for a long time, the condensed water in the water receiving space 231 may have an odor. The provision of a water receiving box prevents the odor from escaping into the indoor space 330, thus ensuring a better user experience.

[0090] Reference Figure 3 and Figure 5 In this embodiment, the air conditioner indoor unit 100 further includes a water level detection switch 250, which is disposed within the water receiving device 230 and is used to detect the height of the water in the water receiving space 231. Furthermore, the drainage pump 210 is configured to activate when the water level in the water receiving space 231 exceeds a preset value and pump the water in the water receiving space 231 into the water supply pipe section 221. This automatically drains condensed water and ensures a pleasant user experience.

[0091] Furthermore, in the prior art, although the solution of embedding the air conditioner in a cabinet can ensure the consistency and aesthetics of the air conditioner indoor unit 100 and other cabinets or household appliances also embedded in the cabinet, the connection holes in the prior art are still exposed to the indoor space 330, affecting the overall aesthetics.

[0092] Reference Figure 7 and Figure 8 In this embodiment, the air-conditioning indoor unit 100 is used to be embeddedly installed inside the cabinet 310; and, a connection hole connecting the indoor space 330 and the outdoor space is opened on the wall 320 of the indoor space 330 where the cabinet 310 is placed. The cabinet 310 covers the connection hole, and the connection hole is opened below the water supply pipe section 221.

[0093] It is understandable that when the cabinet 310 is relatively small and the air conditioning indoor unit 100 can be embedded therein for installation, if the cabinet 310 is to be covered over the connection hole to ensure the aesthetics of the indoor space 330, the connection hole is very likely to be opened at a position higher than the bottom of the air conditioning indoor unit 100. Furthermore, through the arrangement in the above-mentioned embodiment of the present application, the connection hole can be opened at a height corresponding to any position on the wall 320 that is lower than the water supply pipe section 221 and higher than the bottom of the air conditioning indoor unit 100, thereby ensuring the smooth discharge of condensed water from the air conditioning indoor unit 100. Therefore, when the air conditioning indoor unit 100 of this embodiment adopts the embedded installation solution, it can greatly ensure the aesthetics of the indoor space 330 and the smooth discharge of condensed water.

[0094] In addition, as can be seen from the above, if the air-conditioning indoor unit 100 is installed in a wall-mounted manner, the housing 110 of the air-conditioning indoor unit 100 will be entirely exposed in the indoor space 330, resulting in poor consistency and aesthetics among the air-conditioning indoor unit 100, other household appliances, and the cabinets placed in the indoor space 330. Therefore, an installation method in which the air-conditioning indoor unit 100 is embedded in a cabinet can be selected. Currently, in the prior art, some embedded installation methods place the air-conditioning indoor unit 100 directly in the embedded space of the cabinet, on the bottom plate of the cabinet. However, since the center of gravity of the air-conditioning indoor unit 100 is in the middle of the cabinet in the left-right direction, over time, the bottom plate of the cabinet will be bent and deformed in a downward bending in the middle, greatly reducing the overall aesthetics of the embedded installation of the air-conditioning indoor unit 100.

[0095] Reference Figure 1 、 Figure 7 and Figure 8 In the first embodiment of the present invention, the air conditioning indoor unit 100 is embeddedly mounted inside a cabinet 310, and the cabinet 310 has a mounting cavity 311 with a cavity 3111 opening forward. Furthermore, the air conditioning indoor unit 100 includes a plurality of legs 410. The housing 110 is disposed within the mounting cavity 311, with the front side of the housing 110 facing forward through the cavity 3111. The plurality of legs 410 are disposed at the bottom of the housing 110, and are distributed near the left and right ends of the housing 110. The plurality of legs 410 are used to distribute the weight of the air conditioning indoor unit 100 to the left and right sides of the bottom wall of the mounting cavity 311 when the air conditioning indoor unit 100 is supported on the bottom wall of the mounting cavity 311.

[0096] Because the air conditioning indoor unit 100 of this embodiment has multiple legs 410 added to the bottom of the housing 110, and the legs 410 are distributed near the left and right ends of the housing 110, when the air conditioning indoor unit 100 is embedded in the cabinet 310, the legs 410 can distribute the entire weight of the air conditioning indoor unit 100 to the left and right ends of the bottom plate of the cabinet 310. Therefore, this embodiment can effectively prevent the cabinet bottom plate from being bent and deformed downward in the middle when the air conditioning indoor unit 100 is embedded in the cabinet, greatly ensuring the overall aesthetics of the embedded installation of the air conditioning indoor unit 100.

[0097] Reference Figure 1 and Figure 8 In this embodiment, the support leg 410 is in a truncated cone shape, and the area of ​​the end surface of the bottom end of the support leg 410 is smaller than the area of ​​the cross section of the support leg 410 close to the shell 110.

[0098] It can be understood that setting the support leg 410 to be a truncated cone with the area of ​​the end face of the bottom end being smaller than the area of ​​the cross section of the support leg 410 close to the shell 110 can ensure the connection stability between the support leg 410 and the shell 110, so as to ensure the stability of the air-conditioning indoor unit 100 embedded in the interior of the cabinet 310, and at the same time can ensure the distribution effect of multiple support legs 410 to distribute the overall weight of the air-conditioning indoor unit 100 to the left and right ends of the bottom plate of the cabinet 310.

[0099] Reference Figure 1 、 Figure 8 and Figure 11 In this embodiment, the shell 110 includes a cover 112, the base 111 is arranged in the cover 112, and the cover 112 wraps around the front side, top side, bottom side, left side and right side of the base 111, and the support foot 410 is arranged at the bottom of the cover 112.

[0100] It can be understood that in this embodiment, the appearance of most of the air-conditioning indoor unit 100 can be limited by the setting of the cover 112, and ultimately the gravity of the air-conditioning indoor unit 100 can be borne by the cover 112, and the support foot 410 can be set at the bottom of the cover 112.

[0101] In some other embodiments, the cover 112 covers the front side of the base 111 and wraps around the front and top sides of the base 111. That is, the bottom of the base 111 is exposed to the indoor space or the installation cavity of the cabinet 310.

[0102] Furthermore, it should be understood that most of the heavier working components of the air-conditioning indoor unit 100 (eg, the indoor heat exchanger, the indoor fan) are disposed on the base, and thus the base 111 bears most of the weight of the air-conditioning indoor unit 100 .

[0103] Reference Figure 1 and Figure 8 In this embodiment, the support leg 410 is a protruding structure 411 extending downward from the bottom of the housing 110, and the support leg 410 and the housing 110 are an integrated structure.

[0104] It can be understood that by setting the support foot 410 as a protruding structure 411, the air-conditioning indoor unit 100 can be supported on the bottom wall of the installation cavity 311; and by setting the support foot 410 and the shell 110 as an integrated structure, the stability between the support foot 410 and the shell 110 can be ensured, further ensuring the stability of the air-conditioning indoor unit 100 embedded in the interior of the cabinet 310.

[0105] Specifically, when the cover shell 112 is wrapped around the front side, top side, bottom side, left side and right side of the base 111, the support leg 410 can be an integrated structure with the cover shell 112; when the cover shell 112 is wrapped around the front side and top side of the base 111, the support leg 410 can be an integrated structure with the base 111, or the support leg 410 is an integrated structure with the base 111 and the cover shell 112.

[0106] Reference Figure 9 In this embodiment, there are four legs 410 , and the four legs 410 are respectively distributed near the four corners of the bottom of the housing 110 , so as to further ensure the stability of the air conditioner indoor unit 100 embedded in the cabinet 310 .

[0107] When the cover shell 112 is wrapped around the front, top, bottom, left and right sides of the base 111, the four legs 410 can all be set at the bottom of the cover shell 112; when the cover shell 112 is wrapped around the front and top sides of the base 111, the four legs 410 can be arranged in pairs at the bottom of the cover shell 112 and the bottom of the base 111 respectively.

[0108] Reference Figure 10 In a modified embodiment, there are two legs 410, each extending in the front-to-back direction at the bottom of the housing 110. Similarly, the legs 410 can support the air conditioner indoor unit 100 on the bottom wall of the installation cavity 311 and ensure the stability of the air conditioner indoor unit 100 when embedded in the cabinet 310.

[0109] When the cover shell 112 is wrapped around the front side, top side, bottom side, left side and right side of the base 111, the two legs 410 can be both set at the bottom of the cover shell 112, and each leg 410 can be arranged in the front-to-back direction; when the cover shell 112 is wrapped around the front side and top side of the base 111, the two legs 410 can be both connected to the bottom of the base 111, and each leg 410 can extend forward to the bottom of the cover shell 112.

[0110] Furthermore, in the prior art, the air conditioner indoor unit 100 is placed directly in the cabinet's built-in space, on the cabinet's bottom plate. This makes it impossible to adjust the height of the air conditioner indoor unit 100. If a part of the air conditioner indoor unit 100 is too high or too low, or the housing 110 tilts, the air conditioner indoor unit 100 will be unstable in the built-in space. Furthermore, if the air outlet height of the air conditioner indoor unit 100 is not appropriate, the air outlet direction may not meet the user's needs, significantly reducing the user experience.

[0111] Reference Figure 7 and Figure 12In the second embodiment of the present invention, the air conditioner indoor unit 100 is embeddedly mounted within a cabinet 310, and the cabinet 310 has a mounting cavity 311 with a forward opening 3111. Furthermore, the air conditioner indoor unit 100 includes a plurality of legs 410 and a plurality of telescopic structures 420. The housing 110 is disposed within the mounting cavity 311; the plurality of legs 410 are disposed at the bottom of the housing 110; and each telescopic structure 420 is telescopically disposed between the bottom of the housing 110 and a corresponding leg 410. The plurality of telescopic structures 420 are used to adjust the height of at least a portion of the housing 110 within the mounting cavity 311.

[0112] Because the air conditioner indoor unit 100 of this embodiment is equipped with multiple telescopic structures 420 corresponding to the multiple legs 410 and the bottom of the housing 110, these structures are used to adjust the height of at least a portion of the housing 110 within the mounting cavity 311, thereby enabling the adjustment of the height of the air conditioner, either partially or as a whole. When the air conditioner indoor unit 100 is installed in the cabinet 310, if the height of the housing 110 is too high or too low, a single telescopic structure 420 can be used to adjust the entire unit 100. If the height of the air outlet of the air conditioner indoor unit 100 (which may be located on the front side of the housing 110) does not meet the user's air flow requirements, the multiple telescopic structures 420 can be used to adjust the height of the air outlet. Therefore, this embodiment ensures the stability of the air conditioner indoor unit 100 when installed in the cabinet 310, while also ensuring a good user experience.

[0113] Reference Figure 12 In this embodiment, a threaded hole is formed on the bottom of the housing 110 at a position corresponding to the support leg 410. Furthermore, each telescopic structure 420 includes a screw 421. One end of the screw 421 is rotatably connected to the threaded hole, and the other end of the screw 421 is connected to the support leg 410. This allows the telescopic structure 420 to be extended or retracted.

[0114] In a modified embodiment, the telescopic structure 420 can be an electric telescopic rod, a pneumatic push rod, etc. For example, one end of the pneumatic push rod is connected to the bottom of the housing 110, and the other end of the pneumatic push rod is connected to the support leg 410. The telescopic structure 420 can be extended and retracted in the same manner.

[0115] In this embodiment, the support legs 410 are made of rubber.

[0116] It is understood that by making the support legs 410 of rubber to provide a shock-absorbing effect for the air conditioner indoor unit 100, the noise generated during operation of the air conditioner indoor unit 100 can be greatly reduced, thereby improving the user experience. Furthermore, because rubber has a high coefficient of friction, the friction between the support legs 410 and the bottom wall of the installation cavity can be ensured, thereby ensuring the stability of the air conditioner indoor unit 100 when embedded in the cabinet 310.

[0117] Reference Figure 12 and Figure 13 In this embodiment, the support leg 410 is in a circular shape. This ensures that the support leg 410 has a sufficient contact area with the bottom wall of the installation cavity, thereby ensuring the stability of the air conditioner indoor unit 100 when it is embedded in the cabinet 310.

[0118] Reference Figure 11 、 Figure 12 and Figure 13 In this embodiment, the shell 110 includes a cover 112, the base 111 is arranged in the cover 112, and the cover 112 wraps around the front side, top side, bottom side, left side and right side of the base 111, and the support foot 410 is arranged at the bottom of the cover 112.

[0119] It can be understood that in this embodiment, the appearance of most of the air-conditioning indoor unit 100 can be limited by the setting of the cover 112, and ultimately the gravity of the air-conditioning indoor unit 100 can be borne by the cover 112, and the support foot 410 can be set at the bottom of the cover 112.

[0120] In some other embodiments, the cover 112 covers the front side of the base 111 and wraps around the front and top sides of the base 111. That is, the bottom of the base 111 is exposed to the indoor space or the installation cavity of the cabinet 310.

[0121] It should be understood that most of the heavier working components of the air-conditioning indoor unit 100 (for example, the indoor heat exchanger and the indoor fan) are arranged on the base, and thus the base 111 bears most of the weight of the air-conditioning indoor unit 100.

[0122] Reference Figure 12 In this embodiment, the front side surface of the shell 110 is set forward through the cavity 3111; and a plurality of legs 410 are distributed near the left and right ends of the shell 110, so as to distribute the gravity of the air-conditioning indoor unit 100 to the left and right sides of the bottom wall of the installation cavity 311 when the air-conditioning indoor unit 100 is supported on the bottom wall of the installation cavity 311.

[0123] Because the air conditioning indoor unit 100 of this embodiment has multiple legs 410 distributed near the left and right ends of the housing 110, when the air conditioning indoor unit 100 is embedded in the cabinet 310, the multiple legs 410 can distribute the entire weight of the air conditioning indoor unit 100 to the left and right ends of the bottom plate of the cabinet 310. Therefore, this embodiment can effectively prevent the cabinet bottom plate from being bent and deformed downward in the middle when the air conditioning indoor unit 100 is embedded in the cabinet, greatly ensuring the overall aesthetics of the embedded installation of the air conditioning indoor unit 100.

[0124] Reference Figure 13 In this embodiment, there are four legs 410 , and the four legs 410 are respectively distributed near the four corners of the bottom of the housing 110 , so as to further ensure the stability of the air conditioner indoor unit 100 embedded in the cabinet 310 .

[0125] When the cover shell 112 is wrapped around the front, top, bottom, left and right sides of the base 111, the four legs 410 can all be set at the bottom of the cover shell 112; when the cover shell 112 is wrapped around the front and top sides of the base 111, the four legs 410 can be arranged in pairs at the bottom of the cover shell 112 and the bottom of the base 111 respectively.

[0126] Reference Figure 14 In a modified embodiment, there are two legs 410, each extending in the front-to-back direction at the bottom of the housing 110. Similarly, the legs 410 can support the air conditioner indoor unit 100 on the bottom wall of the installation cavity 311 and ensure the stability of the air conditioner indoor unit 100 when embedded in the cabinet 310.

[0127] When the cover shell 112 is wrapped around the front side, top side, bottom side, left side and right side of the base 111, the two legs 410 can be both set at the bottom of the cover shell 112, and each leg 410 can be arranged in the front-to-back direction; when the cover shell 112 is wrapped around the front side and top side of the base 111, the two legs 410 can be both connected to the bottom of the base 111, and each leg 410 can extend forward to the bottom of the cover shell 112.

[0128] Reference Figure 7 and Figure 15In the third embodiment of the present invention, the air conditioning indoor unit 100 is embeddedly mounted within a cabinet 310, and the cabinet 310 has a mounting cavity 311 with an opening 3111 facing forward. Furthermore, the air conditioning indoor unit 100 includes a plurality of brackets 430. The housing 110 is disposed within the mounting cavity 311, with the front side of the housing 110 facing forward through the opening 3111. The plurality of brackets 430 are disposed on the left and right walls 3113 and 3114 of the mounting cavity 311. The plurality of brackets 430 are connected to the left and right ends of the housing 110 to distribute the weight of the air conditioning indoor unit 100 to the left and right walls 3113 and 3114.

[0129] Because the air conditioning indoor unit 100 of this embodiment is additionally equipped with multiple brackets 430, when the air conditioning indoor unit 100 is embedded in the cabinet 310, the multiple brackets 430 are used to be installed on the left side wall 3113 and the right side wall 3114 of the installation cavity 311. The multiple brackets 430 are connected to the left and right ends of the housing 110 to distribute the weight of the air conditioning indoor unit 100 to the left and right sides 3113 and 3114. Therefore, this embodiment can effectively prevent the cabinet bottom plate from being bent and deformed downward in the middle when the air conditioning indoor unit 100 is embedded in the cabinet, greatly ensuring the overall aesthetics of the embedded installation of the air conditioning indoor unit 100.

[0130] In a modified embodiment, the bracket 430 can be a fixing member such as a bolt or a screw, connected between the left side wall 3113 and the left end of the shell 110 / between the right side wall 3114 and the right end of the shell 110.

[0131] Reference Figure 15 In this embodiment, each bracket 430 includes a first plate 431 and a second plate 432. The first plate 431 is attached to the left side wall 3113 or the right side wall 3114. One end of the second plate 432 is connected to the bottom of the first plate 431, and the other end of the second plate 432 extends laterally into the interior of the mounting cavity 311. The housing 110 is placed on the second plate 432.

[0132] It can be understood that the L-shaped bracket 430 formed by the first plate 431 and the second plate 432, while being connected between the left side wall 3113 and the left end of the shell 110 / between the right side wall 3114 and the right end of the shell 110, since the air-conditioning indoor unit 100 is placed as a whole on the second plate 432, the contact area between the air-conditioning indoor unit 100 and the bracket 430 can be effectively guaranteed to ensure the connection stability between the air-conditioning indoor unit 100 and the bracket 430, so as to further ensure the installation stability of the air-conditioning indoor unit 100 when installed inside the cabinet 310.

[0133] In addition, the first plate 431 can be connected to the left side wall 3113 / the right side wall 3114 by fasteners such as screws.

[0134] In addition, the second plate 432 can also be connected to the bottom of the housing 110 by fasteners such as screws to ensure the connection stability between the bracket 430 and the air conditioner indoor unit 100.

[0135] Reference Figure 11 and Figure 15 In this embodiment, the shell 110 includes a cover 112, the base 111 is arranged in the cover 112, and the cover 112 wraps the front side, top side, bottom side, left side and right side of the base 111, and the bracket 430 is arranged at the bottom of the cover 112.

[0136] It can be understood that in this embodiment, the appearance of most of the air-conditioning indoor unit 100 can be limited by the setting of the cover 112, and ultimately the gravity of the air-conditioning indoor unit 100 can be borne by the cover 112, and the bottom of the cover 112 can be set on the second plate 432 of the bracket 430.

[0137] In some other embodiments, the cover 112 covers the front side of the base 111 and wraps around the front side and top side of the base 111. That is, the bottom of the base 111 is exposed to the indoor space or the installation cavity of the cabinet 310.

[0138] It should be understood that most of the heavier working components of the air-conditioning indoor unit 100 (for example, the indoor heat exchanger and the indoor fan) are arranged on the base, and thus the base 111 bears most of the weight of the air-conditioning indoor unit 100.

[0139] Reference Figure 16 In this embodiment, there are four brackets 430, each of which is disposed in pairs on the left side wall 3113 and the right side wall 3114 of the installation cavity 311. Furthermore, the four brackets 430 are disposed near the four corners of the bottom of the housing 110. This further ensures the stability of the air conditioner indoor unit 100 when embedded in the cabinet 310.

[0140] Moreover, when the cover shell 112 is wrapped around the front side, top side, bottom side, left side and right side of the base 111, the four brackets 430 can be set at the bottom of the cover shell 112; when the cover shell 112 is only wrapped around the front side and top side of the base 111, the four brackets 430 can be arranged in pairs at the bottom of the cover shell 112 and the bottom of the base 111 respectively.

[0141] Reference Figure 17In a modified embodiment, two brackets 430 are provided, each extending in the front-to-back direction at the bottom of the housing 110. This allows the indoor air conditioner 100 to be placed on the bottom wall of the mounting cavity 311, ensuring stability when embedded within the cabinet 310.

[0142] Moreover, when the cover shell 112 is wrapped around the front side, top side, bottom side, left side and right side of the base 111, both brackets 430 can be set at the bottom of the cover shell 112; when the cover shell 112 is only wrapped around the front side and top side of the base 111, both brackets 430 can be connected to the bottom of the base 111, and each bracket 430 can extend forward to the bottom of the cover shell 112.

[0143] Furthermore, in the prior art, a wall-mounted air conditioner indoor unit 100 is typically mounted on the wall of the indoor space 330 by drilling a hole therein, securing a mounting plate to the wall using expansion bolts and the expansion hole. The unit is then hung on the mounting plate using a hanger provided on the back of the unit 100, thereby allowing the unit to be hung on the wall as a whole. However, this installation method inevitably causes the top of the unit 100 to tilt forward, as the center of gravity of the unit 100 is located in front of the mounting plate, and components such as the mounting plate and hanger are located between the back of the unit 100 and the wall 320. If the distance between the top of the air conditioner indoor unit 100 and the ceiling 331 of the indoor space 330 is too small, the rear end of the top of the air conditioner indoor unit 100 may touch the ceiling 331 of the indoor space 330, resulting in a gap. This reduces the space between the top of the air conditioner indoor unit 100 and the ceiling 331, affecting the air intake of the air conditioner indoor unit 100 and its performance in heating, cooling, and other modes. In addition, after long-term use, when the air conditioner indoor unit 100 is wall-mounted using expansion screws and expansion holes, the expansion holes in the wall will expand downward due to the downward force of the air conditioner indoor unit 100. The friction between the expansion screws and the expansion holes will decrease, causing the expansion screws to loosen. Under the action of gravity, the tilted air conditioner indoor unit 100 will fall, leading to safety issues.

[0144] Reference Figure 18 、 Figure 20 、 Figure 21 or Figure 22 ,as well as Figure 19In the fourth implementation of the present embodiment, the air conditioner indoor unit 100 includes a hoisting device 500, which is used to hoist the air conditioner indoor unit 100 into the installation space 340. The hoisting device 500 includes a hook 510 and a bracket 520. The hook 510 includes a first connecting plate 511 and a second connecting plate 512. The first connecting plate 511 extends in the up-down direction. The bottom end of the first connecting plate 511 is used to be connected to the top of the shell 110. The top end of the first connecting plate 511 extends upward and is used to abut against the top wall 341 of the installation space 340. One end of the second connecting plate 512 is connected to the first side surface 5111 of the first connecting plate 511, and the other end of the second connecting plate 512 extends in a direction away from the first side surface 5111. The bracket 520 is used to be arranged on the top wall 341, and the bracket 520 is arranged relative to the first side surface 5111. A hanging groove 521 opening toward the first side surface 5111 is provided on the bracket 520, and the second connecting plate 512 is arranged in the hanging groove 521.

[0145] Reference Figure 18 or Figure 21 In the first application mode of the lifting device 500 of this embodiment, the first connecting plate 511 can be used to be set close to the front end of the shell 110, and the first side surface 5111 can be used to be set backward to enable the first connecting plate 511 to limit the air-conditioning indoor unit 100 from tilting its bottom end forward by its own gravity.

[0146] Since the air conditioning indoor unit 100 of this embodiment is additionally provided with a hanging device 500, and the hanging device 500 is used to hang the air conditioning indoor unit 100 in the installation space 340, the hanging device 500 specifically includes a hanger 520 and a hook 510. The hanger 520 is mounted on the top wall 341 of the installation space 340, and the second connecting plate 512 of the hook 510 is hung in the hanging groove 521. The first connecting plate 511 of the hanger is disposed at the top of the housing 110 near the front end. As a result, the center of gravity of the air conditioning indoor unit 100 is located behind the hanger 520, and the top end of the first connecting plate 511 extends upward to contact the top wall 341 of the installation space 340. As a result, the first connecting plate 511 can prevent the bottom end of the air conditioning indoor unit 100 from tilting forward due to its own weight, thereby effectively preventing the formation of a gap and preventing the space between the top end of the air conditioning indoor unit 100 and the top wall 341 of the installation space 340 from being reduced. At the same time, if the bracket 520 is installed on the top wall 341 of the installation space 340 using expansion screws and expansion holes, the first connecting plate 511 ensures that the force exerted by the air conditioner indoor unit 100 on the bracket 520 is always directed vertically downward, and the expansion hole will not be expanded by the gravity of the air conditioner indoor unit 100. This effectively ensures the friction between the expansion screws and the expansion hole, thereby effectively preventing the air conditioner indoor unit 100 from falling. Therefore, the hanging device 500 of this embodiment can ensure the air intake and operating performance of the air conditioner indoor unit 100, and greatly ensure the installation stability and operational safety of the air conditioner indoor unit 100 within the installation space 340.

[0147] Moreover, since the center of gravity of the air-conditioning indoor unit 100 is located behind the bracket 520, and the second connecting plate 512 is also inserted into the hanging groove 521 toward the rear, then, under the action of the gravity of the air-conditioning indoor unit 100, the second connecting plate 512 has a tendency to move deeper into the hanging groove 521, so as to further ensure the installation stability and use safety of the air-conditioning indoor unit 100 in the installation space 340.

[0148] Reference Figure 20 and Figure 22In the second application of the hanging device 500 of this embodiment, the first connecting plate 511 can be positioned near the rear end of the housing 110, and the first side surface 5111 can be positioned forward, so that the first connecting plate 511 can limit the backward tilting of the bottom end of the air conditioning indoor unit 100 due to its own weight. For the same reasons as the first embodiment of the hanging device 500, this embodiment can also effectively prevent the formation of flash gaps and the reduction of the space between the top of the air conditioning indoor unit 100 and the top wall 341 of the installation space 340; and effectively prevent the air conditioning indoor unit 100 from falling. Furthermore, the hanging device 500 of this embodiment can ensure the air intake and operating performance of the air conditioning indoor unit 100, and greatly ensure the installation stability and operational safety of the air conditioning indoor unit 100 within the installation space 340.

[0149] In a modified embodiment, the first connecting plate 511 is used to connect to the middle of the shell 110 in the front-to-back direction, so that the center of gravity of the air-conditioning indoor unit 100 and the first connecting plate 511 are on a vertical line, thereby greatly avoiding the tilting caused by the center of gravity.

[0150] Reference Figure 18 In this embodiment, the vertical height H of the first connecting plate 511 is equal to the vertical width K of the bracket 520 . This allows the bottom end of the first connecting plate 511 to be connected to the top of the housing 110 , and the top end of the first connecting plate 511 to abut against the top wall 341 of the installation space 340 .

[0151] Reference Figure 20 In this embodiment, the thickness L of the second connecting plate 512 in the vertical direction is equal to or slightly greater than (interference fit) the width N of the hanging groove 521 in the vertical direction. This further limits the forward or backward tilting of the bottom end of the air conditioning indoor unit 100, further ensuring the air intake and operating performance of the air conditioning indoor unit 100.

[0152] Reference Figure 18 and Figure 20 In this embodiment, the rear side of the shell 110 can be against the rear wall of the installation space 340 to further ensure the air intake and working performance of the air-conditioning indoor unit 100, as well as the installation stability of the air-conditioning indoor unit 100 in the installation space 340.

[0153] Reference Figure 18 In this embodiment, when the first connecting plate 511 is used to be set close to the front end of the shell 110 and the first side surface 5111 is used to be set toward the rear, the front side surface of the first connecting plate 511 can be on the same plane as the front side surface of the shell 110.

[0154] It should be understood that by arranging the front side of the first connecting plate 511 to be on the same plane as the front side of the housing 110, the front side of the air conditioning indoor unit 100 can be made very flat, thereby ensuring the aesthetics of the air conditioning indoor unit 100.

[0155] Reference Figure 18 、 Figure 20 、 Figure 21 and Figure 22 In this embodiment, the housing 110 and the hook 510 are an integrated structure.

[0156] It is understandable that by providing the hook 510 and the housing 110 as an integrated structure, the connection stability between the housing 110 and the bracket 520 can be ensured, thereby further ensuring the stability of the air conditioner indoor unit 100 when installed in the installation space 340.

[0157] In this embodiment, the shell 110 includes a cover 112, the base 111 is arranged in the cover 112, and the cover 112 wraps the front side, top side, bottom side, left side and right side of the base 111, and the hook 510 and the cover 112 are an integrated structure.

[0158] It is understood that in this embodiment, the housing 112 can define most of the appearance of the air conditioning indoor unit 100, and ultimately the housing 112 can bear the weight of the air conditioning indoor unit 100, thereby connecting the hook 510 to the housing 112. In addition, the hook 510 and the housing 112 are provided as an integrated structure, which can further ensure the stability of the air conditioning indoor unit 100 when installed in the installation space 340.

[0159] In some other embodiments, the cover 112 covers the front side of the base 111 and wraps around the front and top sides of the base 111. That is, the bottom of the base 111 is exposed to the indoor space or the installation cavity of the cabinet 310. The hook 510 is provided on the base 111, and the hook 510 and the base 111 are integrally formed.

[0160] It should be understood that most of the heavier working components of the air conditioner indoor unit 100 (e.g., the indoor heat exchanger and the indoor fan) are mounted on the base, and thus the base 111 bears the majority of the weight of the air conditioner indoor unit 100. Furthermore, a scheme can be adopted in which the first connecting plate 511 is positioned near the rear end of the housing 110 and the first side surface 5111 is positioned forward, with the hook 510 positioned on the base to ensure the stability of the installation of the air conditioner indoor unit 100 and the installation space 340. Furthermore, the hook 510 and the base 111 are configured as an integrated structure to further ensure the stability of the installation of the air conditioner indoor unit 100 and the installation space 340.

[0161] Reference Figure 19 In this embodiment, the hanger 520 includes a base plate 522, a first hanging plate 523, and a second hanging plate 524. The base plate 522 is connected to the top wall 341. One end of the base plate 522 and one end of the second hanging plate 524 are connected to the same side of the second hanging plate 524. The second hanging plate 524 is located below the base plate 522, and the hanging slot 521 is located between the base plate 522, the first hanging plate 523, and the second hanging plate 524. This facilitates the creation of the hanging slot 521 and the installation of the hanger 520. Furthermore, the base plate 522 and the second hanging plate 524 extend in the front-to-back direction, while the first hanging plate 523 extends in the top-to-bottom direction.

[0162] In a modified embodiment, the hanger 520 may be a block-shaped structure, and the hanging groove 521 is formed from the outside to the inside of the block-shaped structure.

[0163] Reference Figure 23 In this embodiment, the base plate 522 is provided with first mounting holes 5221 arranged in the up and down directions, and a connecting member 5222 is connected in the first mounting hole 5221, and the connecting member 5222 is used to be connected to the top wall 341; the second hanging plate 524 is provided with a second mounting hole 5223 at a position corresponding to the first mounting hole 5221, and the second mounting hole 5223 is used to allow the connecting member 5222 to be connected in the first mounting hole 5221 and on the top wall 341.

[0164] It is understandable that the opening of the first mounting hole 5221 facilitates the installer to fix the bracket 520 to the top wall 341 of the installation space 340 through the connector 5222, thereby facilitating the installer's installation of the air conditioner indoor unit 100. In addition, the connector 5222 can be a fixing member such as an expansion bolt, a screw nut, etc.

[0165] Reference Figure 23 In this embodiment, there are multiple first mounting holes 5221, and the multiple first mounting holes 5221 are opened in the left-right direction on the base plate 522. This ensures the stability of the connection between the bracket 520 and the top wall 341 of the installation space 340, further ensuring the safety of the air conditioner indoor unit 100.

[0166] In this embodiment, the number of the hangers 520 and the hooks 510 are both set to multiple, and the multiple hangers 520 are arranged in the left-right direction, and the multiple hooks 510 correspond to the multiple hangers 520 arranged in the left-right direction, so as to further ensure the safety of the air conditioner indoor unit 100.

[0167] Reference Figure 23 In this embodiment, the hanging groove 521 is connected to the left and right ends of the hanging bracket 520.

[0168] It should be noted that when installing the air-conditioning indoor unit 100, the bracket 520 can be first installed on the top wall 341 of the installation space 340 through the connecting piece 5222, and since the hanging groove 521 is a through groove connecting the left and right ends of the bracket 520, the bracket 520 and the hook 510 can be misaligned, and then the air-conditioning indoor unit 100 and the hook 510 can be pushed to move in the left and right directions, so that the hook 510 and the bracket 520 are installed in place, and then the installation of the air-conditioning indoor unit 100 is completed.

[0169] Reference Figure 18 and Figure 20 In this embodiment, the installation space 340 is the indoor space 330 , and the top wall 341 is the ceiling 331 .

[0170] It is understandable that the air-conditioning indoor unit 100 of this embodiment may be a wall-mounted air-conditioning indoor unit 100 in the prior art that adopts a hoisting installation method.

[0171] Reference Figure 21 and Figure 22 In this embodiment, the air-conditioning indoor unit 100 is used to be embeddedly installed inside the cabinet 310, and the installation space 340 is an installation cavity 311 of the cabinet 310 with a cavity 3111 opened forward, and the top wall 341 is the top plate 3112 of the cabinet 310 that forms the installation cavity 311; and the front side surface of the shell 110 is set forward through the cavity 3111.

[0172] It is understood that the air conditioning indoor unit 100 of this embodiment can also be embedded in the interior of the cabinet by being hoisted on the top plate 3112 of the cabinet body 310, thereby preventing the middle portion of the cabinet's bottom plate from being bent. Therefore, the hoisting device 500 of this embodiment can ensure the air intake and operating performance of the air conditioning indoor unit 100, while greatly ensuring the installation stability and operational safety of the air conditioning indoor unit 100 within the installation cavity 311. It can also effectively prevent the cabinet's bottom plate from being bent and deformed downward in the middle when the air conditioning indoor unit 100 is embedded in the cabinet, thereby greatly ensuring the overall aesthetics of the embedded installation of the air conditioning indoor unit 100.

[0173] It should also be noted that, regardless of whether the air-conditioning indoor unit 100 is hoisted in the indoor space 330 through the hoisting device 500, or is hoisted in the installation cavity 311 in the cabinet 310, the connecting piece 5222 from the mounting bracket 520 to the top wall 341 may not adopt the ordinary expansion bolt and expansion hole structure, but may adopt a through-type expansion bolt and expansion through-hole installation method or directly use a screw 421 and nut and other structures to penetrate the ceiling 331 or the top plate 3112 of the cabinet 310, so as to further ensure the installation stability of the air-conditioning indoor unit 100 and avoid the occurrence of safety problems.

[0174] Reference Figure 7 、 Figure 24 and Figure 26 In this embodiment, the air conditioning indoor unit 100 is embedded in a cabinet 310. The cabinet 310 has a mounting cavity 311 with a forward opening 3111. A cabinet door 350 is rotatably connected to the cabinet 310 for opening or closing the opening 3111. The air conditioning indoor unit 100 also includes a telescopic rod 610. The housing 110 is disposed within the mounting cavity 311, with the front side of the housing 110 facing forward through the opening 3111. The rear end of the telescopic rod 610 is connected to the housing 110, and the telescopic end of the telescopic rod 610 is connected to the cabinet door 350. The telescopic rod 610 is configured to extend and cause the cabinet door 350 to open when the air conditioning indoor unit 100 receives a first preset command, and to shorten and cause the cabinet door 350 to close when the air conditioning indoor unit 100 receives a second preset command.

[0175] Since the air conditioning indoor unit 100 of this embodiment is additionally provided with a telescopic rod 610, and the tail end of the telescopic rod 610 is connected to the housing 110, and the telescopic end of the telescopic rod 610 is used to connect to the cabinet door 350, the telescopic rod 610 is used to extend and cause the cabinet door 350 to open when the air conditioning indoor unit 100 receives a first preset command (for example, a power-on command), and to shorten and cause the cabinet door 350 to close when the air conditioning indoor unit 100 receives a second preset command (for example, a power-off command). Furthermore, the air conditioning indoor unit 100 can open and close the cabinet door 350 without human intervention. Therefore, after the air conditioning indoor unit 100 of this embodiment is installed, the cabinet door 350 can be opened and closed without the user having to do it themselves, thereby improving the user experience.

[0176] It should also be noted that when the air-conditioning indoor unit 100 is embedded in the cabinet body 310 using the L-shaped bracket 430 of the above embodiment, the connection between the bracket 430 and the shell 110 can also be connected by screws, snap-fit ​​parts or bolts, or the bracket and 430 and the shell 110 can be set as an integrated structure to ensure the stability of the telescopic rod 610 in the process of prompting the cabinet door 350 to open or close.

[0177] In addition, if the air conditioner indoor unit 100 is damaged, the cabinet door 350 may not be opened properly. Furthermore, if the telescopic end of the telescopic rod 610 and the cabinet door 350 are fixedly connected or hinged, the telescopic rod 610 may prevent the user or maintenance personnel from manually opening the cabinet door 350 to repair the air conditioner indoor unit 100.

[0178] Reference Figure 7 、 Figure 24 、 Figure 25 and Figure 26In this embodiment, the telescopic end of the telescopic rod 610 is used to contact the inner side surface of the cabinet door 350.

[0179] It should be understood that the connection between the telescopic end of the telescopic rod 610 and the cabinet door 350 is configured as a contact-type connection. Thus, the air conditioner indoor unit 100 can use the telescopic rod 610 to propel the closed cabinet door 350 to an open state. Furthermore, when the cabinet door 350 is closed, due to the contact-type connection between the telescopic end of the telescopic rod 610 and the cabinet door 350, if the air conditioner indoor unit 100 is unable to open the cabinet door 350 normally, the user or maintenance personnel can manually open the air conditioner indoor unit 100.

[0180] Furthermore, when the air conditioner indoor unit needs to be powered off, as described in the following embodiments, the telescopic end of the telescopic rod 610 is not fixedly connected to the cabinet door 350, so the user can directly manually open the cabinet door 350 (and use the mechanical power switch 710 in the following embodiments) to power off the air conditioner indoor unit 100, and then manually close the cabinet door 350 after the power is turned off. Furthermore, by configuring the telescopic end of the telescopic rod 610 to contact the inner side of the cabinet door 350, it is possible to effectively avoid situations where the user cannot open the cabinet door 350 due to the telescopic rod 610, and situations where the cabinet door 350 cannot be closed after the cabinet door 350 is opened to power off the air conditioner 100.

[0181] Reference Figure 25 In this embodiment, the air conditioning indoor unit 100 further includes a rolling member 620 . The rolling member 620 is rotatably connected to the telescopic end of the telescopic rod 610 , and the rolling member 620 is used to roll in contact with the inner side of the cabinet door 350 .

[0182] It can be understood that, through the setting of the rolling member 620, it can be ensured that when the telescopic rod 610 opens the cabinet door 350 (or when the cabinet door 350 is closed as the telescopic rod 610 is retracted), the contact mode between the telescopic rod 610 and the cabinet door 350 is rolling contact, so as to ensure the stability of the cabinet door 350 during the opening (or closing) process.

[0183] Reference Figure 25 In this embodiment, the rolling element 620 is a roller 621 , and the rotation center axis of the roller 621 is arranged parallel to the rotation center axis of the cabinet door 350 .

[0184] It is understandable that the roller 621, as a specific implementation of the rolling element 620, can ensure the stability of the cabinet door 350 during the opening (or closing) process.

[0185] In a modified embodiment, the rolling element 620 is a ball, which can also ensure the stability of the cabinet door 350 during the opening (or closing) process.

[0186] In addition, although the cabinet door 350 and the telescopic rod 610 are connected in a contact manner, when the cabinet door 350 is in an open state, the telescopic rod 610 is shortened and cannot complete the closing of the cabinet door 350.

[0187] Reference Figure 7 、 Figure 24 In the first embodiment of the cabinet door 350 being closed, the cabinet door 350 is rotatably connected to the top of the cabinet body 310 .

[0188] It is understandable that, since the cabinet door 350 itself has gravity, when the telescopic end of the telescopic rod 610 is retracted, the cabinet door 350 can automatically close the cavity 3111 even if the connecting rope 630 is not provided.

[0189] Reference Figure 24 and Figure 25 In the second implementation of closing the cabinet door 350 of the present embodiment, the air-conditioning indoor unit 100 further includes a connecting rope 630. One end of the connecting rope 630 is connected to the telescopic end of the telescopic rod 610, and the other end of the connecting rope 630 is connected to the inner side of the cabinet door 350. The connecting rope 630 is used to drive the cabinet door 350 in the open state to rotate and close the cavity 3111 when the telescopic rod 610 is shortened. Furthermore, when the cabinet door 350 and the telescopic rod 610 are connected in a contact-type manner, the cabinet door 350 can also be closed by the connecting rope 630 when the telescopic rod 610 is shortened. And when the hinge resistance of the cabinet door 350 is large and cannot be self-closed, the cabinet door 350 can be closed by setting a connecting rope 630.

[0190] Furthermore, the connecting rope 630 can be a steel wire rope to ensure that the cabinet door 350 can be moved effectively when the telescopic rod 610 is shortened. The connecting rope 630 can also be a flexible connecting rope, for example, a rope made of a polymer material such as polyester fiber, to prevent the connecting rope 630 from obstructing the movement of the cabinet door 350 when the telescopic rod 610 is shortened to close the cabinet door 350.

[0191] Reference Figure 24 and Figure 25 In this embodiment, the air conditioner indoor unit 100 further includes a first lifting eye 640 and a second lifting eye 650. The first lifting eye 640 is configured to be mounted on the inner side of the cabinet door 350; the second lifting eye 650 is mounted on the telescopic end of the telescopic rod 610, and one end of the connecting rope 630 is connected to the second lifting eye 650, while the other end of the connecting rope 630 is connected to the first lifting eye 640.

[0192] It is understandable that, by providing the first lifting lug 640 and the second lifting lug 650 , the connection stability between the connecting rope 630 , the telescopic rod 610 and the cabinet door 350 can be improved, thereby ensuring the stability of the cabinet door 350 during the closing process.

[0193] In a modified implementation manner of the cabinet door 350 being closed in this embodiment, an elastic member is connected between the cabinet door 350 and the cabinet body 310 , and the elastic member is used to keep the cabinet door 350 in a closed state.

[0194] It is understood that, by providing the elastic member, when the telescopic rod 610 is extended, the elastic force of the elastic member can be overcome to open the cabinet door 350; when the telescopic rod 610 is shortened, the cabinet door 350 can rely on the elastic force to close the cavity 3111. The elastic member can be a spring, a shrapnel, etc.

[0195] Reference Figure 24 and Figure 27 In this embodiment, the telescopic end of the telescopic rod 610 is tilted toward the connection axis between the cabinet door 350 and the cabinet body 310 .

[0196] It should be understood that by tilting the telescopic end of the telescopic rod 610 toward the connecting axis between the cabinet door 350 and the cabinet body 310, the telescopic rod 610 can fully extend the cabinet door 350 with a shorter telescopic stroke while requiring less force to open the cabinet door 350. Furthermore, the stability of the cabinet door 350 during opening and closing can be ensured.

[0197] Reference Figure 24 and Figure 27 In this embodiment, the housing 110 includes a cover 112 . The cover 112 is disposed in front of the base 111 , the tail end of the telescopic rod 610 is connected to the base 111 , and the telescopic end of the telescopic rod 610 passes through the cover 112 and is connected to the cabinet door 350 .

[0198] It is understood that because the base 111 bears most of the gravity of the air conditioner indoor unit 100, it has strong stability. Furthermore, the telescopic rod 610 can be mounted on the base 111 of the housing 110 to ensure stability when the telescopic rod 610 initiates the closing process of the cabinet door 350. Furthermore, the base 111 is a load-bearing component extending in the left-right direction. Therefore, the base 111 can accommodate a wide range of fixed components and a wide range of fixing solutions, and the tail end of the telescopic rod 610 can be connected to the base 111.

[0199] In addition, the tail end of the telescopic rod 610 can also be connected to the inner wall of the cover 112. Since the cover 112 can withstand the gravity of the base 111 in this embodiment, and thus the cover 112 also has strong stability, the tail end of the telescopic rod 610 can also be connected to the inner wall of the cover 112, which can also ensure the stability of the telescopic rod 610 in the process of prompting the cabinet door 350 to start closing.

[0200] Reference Figure 7 、 Figure 24 and Figure 27 In this embodiment, the cabinet door 350 is rotatably connected to the top of the cabinet body 310; the tail end of the telescopic rod 610 is connected to the right end / left end of the base 111, and the telescopic end of the telescopic rod 610 is tilted toward the top of the cabinet body 310.

[0201] It is understood that since the cabinet door 350 can be self-closed by its own gravity when rotatably connected to the top of the cabinet body 310, this embodiment can be implemented as a preferred embodiment. In addition, since the air conditioner indoor unit 100, an important component for achieving cooling and heating, needs to be located directly in front of the base 111, the tail end of the telescopic rod 610 can be located near the right end / left end of the base 111.

[0202] Reference Figure 24 In this embodiment, the telescopic rod 610 is an electric push rod 611 .

[0203] It is understandable that since the operation of the air conditioning indoor unit 100 requires electrical energy, when the telescopic rod 610 adopts the electric push rod 611, there is no need to set up an additional power source, which reduces the production cost of the air conditioning indoor unit 100.

[0204] In a modified embodiment, the telescopic rod 610 may also be a pneumatic push rod or a hydraulic push rod.

[0205] In a modified embodiment, a drive device is provided at the rear end of the telescopic rod 610, and the drive device is disposed on the housing 110 (base 111). The drive device is used to drive the telescopic rod 610 to rotate around the drive device, and the rotation direction of the telescopic rod 610 is the same as the opening or closing direction of the cabinet door 350. This can greatly ensure the stability of the telescopic rod 610 during the process of opening or closing the cabinet door 350.

[0206] For example, when the cabinet door 350 is rotatably connected to the top of the cabinet body 310, the drive device can drive the telescopic end of the telescopic rod 610 to move vertically and rotate about the drive device. Specifically, when the cabinet door 350 is closed, the telescopic end of the telescopic rod 610 is located at the bottom of the cabinet door 350. As the telescopic rod 610 extends, the cabinet door 350 is pushed open, and the telescopic end of the telescopic rod 610 moves upward. When the cabinet door 350 is open, the telescopic end of the telescopic rod 610 is located near the rotational axis of the cabinet door 350. As the telescopic rod 610 shortens, the cabinet door 350 is closed, and the telescopic end of the telescopic rod 610 moves downward. This greatly ensures the stability of the telescopic rod 610 during the process of opening or closing the cabinet door 350.

[0207] Furthermore, the air conditioner often needs to be powered off, for example, for maintenance and repair, and in northern my country, when the air conditioner is plugged in during summer heat surges, or when the heating is on in winter. After the air conditioner indoor unit 100 is installed in the cabinet's mounting cavity 311, the cabinet's space for installing the air conditioner indoor unit 100 is relatively small. Regardless of whether the socket is located on the rear wall, top wall 341, bottom wall, or left or right side walls of the cabinet's mounting cavity 311, unplugging the already plugged-in power plug 720 of the air conditioner indoor unit 100 and powering off the air conditioner is very inconvenient, thereby reducing the user's experience with the air conditioner.

[0208] Reference Figure 7 、 Figure 28 In this embodiment, the air-conditioning indoor unit 100 is used to be embeddedly installed inside the cabinet 310, and the cabinet 310 has an installation cavity 311 with a cavity 3111 opened forward; and the shell 110 is used to be set in the installation cavity 311, and the front side of the shell 110 is set forward through the cavity 3111; the air-conditioning indoor unit 100 includes a mechanical power switch 710, which is set on the shell 110 and exposed to the indoor space 330 through the cavity 3111. The input end of the mechanical power switch 710 is connected to the power socket 730 through the plug 720, and the output end of the mechanical power switch 710 is connected to the power supply line of the air-conditioning indoor unit 100 (for example, the online line of the electrical box). The mechanical power switch 710 is used to be manually cut off or connected to the power supply from the power socket 730 to the air-conditioning indoor unit 100.

[0209] The air conditioner indoor unit 100 is equipped with a mechanical power switch 710. The mechanical power switch 710 is disposed on the housing 110 and exposed to the indoor space 330 through the cavity 3111. The input end of the mechanical power switch 710 is connected to the power outlet 730 via a plug 720, and the output end of the mechanical power switch 710 is connected to the power supply line of the air conditioner indoor unit 100. The mechanical power switch 710 is used to manually disconnect or connect the power supply from the power outlet 730 to the air conditioner indoor unit 100. Furthermore, users or maintenance personnel can conveniently power on or off the air conditioner using the mechanical power switch 710. Therefore, this embodiment ensures a user-friendly experience when using the air conditioner indoor unit 100.

[0210] In alternative embodiments, the mechanical power switch 710 may be disposed on the front side of the housing 112 .

[0211] Reference Figure 28In this embodiment, the mechanical power switch 710 is arranged on the front side of the base 111; an air inlet 1122 is opened on the cover 112, and the mechanical power switch 710 is arranged corresponding to the air inlet 1122, and an air inlet grille 1121 is detachably connected to the cover 112 at a position corresponding to the air inlet 1122; and when the air inlet grille 1121 opens the air inlet 1122, the mechanical power switch 710 is exposed forward to the indoor space 330 through the cavity 3111 and the air inlet 1122.

[0212] It is understood that by disposing the mechanical power switch 710 inside the housing 110 (between the cover 112 and the base 111), it is possible to ensure that the mechanical power switch 710 is not exposed to the indoor space 330 even when the air conditioner indoor unit 100 is operating in cooling, heating, or other modes, thereby ensuring the aesthetics of the indoor space 330, the cabinet 310, and the air conditioner indoor unit 100. The mechanical power switch 710 is only exposed to the indoor space 330 when it is necessary to power off the air conditioner indoor unit 100 by removing the air inlet grille 1121, thereby further ensuring a better user experience.

[0213] Reference Figure 28 In this embodiment, the air conditioner indoor unit 100 further includes a filter 140. The filter 140 is detachably mounted on the housing 112 and blocks the air inlet 1122. The filter 140 is configured to filter the airflow entering the housing 110 through the air inlet 1122. The filter 140 is located in front of the mechanical power switch 710 and behind the air inlet grille 1121. When the air inlet grille 1121 and the filter 140 open the air inlet 1122, the mechanical power switch 710 is exposed forwardly to the indoor space 330 through the cavity 3111 and the air inlet 1122.

[0214] It is understood that the installation of the filter 140 ensures the cleanliness of the airflow entering the air conditioner indoor unit 100 and the operating performance of the air conditioner indoor unit 100. When the user needs to power off the air conditioner indoor unit 100, the user / maintenance personnel can check the dust accumulation level of the filter 140, further reminding the user / maintenance personnel to clean the filter 140. This ensures the filter 140's filtering effect on the airflow, ensures the cleanliness of the airflow outflowing from the air conditioner indoor unit 100, protects the user's physical and mental health, and enhances the user experience.

[0215] Reference Figure 28 and Figure 29In this embodiment, a heat exchanger frame 121 is provided at the lateral end of the indoor heat exchanger 120 , and the mechanical power switch 710 is provided on the heat exchanger frame 121 , and the mechanical power switch 710 is located in front of the indoor heat exchanger 120 and the heat exchanger frame 121 .

[0216] It is understandable that since the heat exchanger frame 121 is close to the electronic control components of the air conditioner indoor unit 100 and can be exposed to the indoor space 330 through the air inlet 1122 of the cover 112, the structure of the original air conditioner indoor unit 100 is not changed as much as possible, the cost of producing the air conditioner is minimized while making it easier for users to power off the air conditioner. For example, the exposed power plug 720 of the original air conditioner indoor unit 100 is connected to the air conditioner through a power supply line (online line) to its electronic control components, and the electronic control components are located at the lateral end of the indoor heat exchanger 120, usually the right end of the indoor heat exchanger 120. Therefore, the mechanical power switch 710 is added here, eliminating the need to rewire the exposed power plug 720 from the inside of the housing 110 to the outside of the housing 110 and re-open the mold of the housing 110.

[0217] In this embodiment, the mechanical power switch 710 is a knob switch, a button switch, a rocker switch, a knife switch, or a pull switch. For example, the mechanical power switch 710 can be an air circuit breaker.

[0218] In this embodiment, when the air-conditioning indoor unit 100 is provided with a mechanical power switch 710 and a telescopic rod 610, the embedded cabinet can preferably be a cabinet in which the cabinet door 350 is rotatably connected to the top of the cabinet body 310, or a cabinet in which an elastic part is provided between the cabinet door 350 and the cabinet body 310.

[0219] The following describes in detail the hanging device 500 of the air conditioner indoor unit 100 of this embodiment.

[0220] In this embodiment, the hoisting device 500 is used to hoist the air conditioner indoor unit 100 into the installation space 340. In addition, the structure and beneficial technical effects of the hoisting device 500 have been described in the above embodiments and will not be repeated here.

[0221] In a modified embodiment, the hook 510 may be connected to the top of the housing 110 by means of fasteners such as bolts and screws, that is, the hook 510 and the housing 110 may not be an integrated structure.

[0222] At this point, those skilled in the art will recognize that, although a number of exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications consistent with the principles of the present invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the present invention.
