Description

Technical Field

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

[0002] With the development of science and technology, the number of air conditioners is increasing, and people's demand for them has become indispensable. When the air conditioner is running in cooling mode, a large amount of condensed water is attached to its indoor heat exchanger, and as the amount of attachment increases, the condensed water will flow down from the indoor heat exchanger.

[0003] At present, in the prior art, a water receiving trough is provided in the indoor unit of the air conditioner to receive the condensed water flowing down from the indoor heat exchanger, and a drainage pipe is provided in the connection pipe between the outdoor unit and the indoor unit of the air conditioner, one end of the drainage pipe is connected to the water receiving trough, and the other end of the drainage pipe extends to the outside through the connection hole on the wall, and then when the air conditioner is running in the cooling mode, the condensed water generated on the indoor heat exchanger will flow through the water receiving trough and the drainage pipe to the outside, so as to avoid the condensed water flowing into the indoor space and dirtying the indoor floor, so as to ensure the user's experience of using the air conditioner. However, since the air conditioner relies on gravity to drain water, to ensure that the condensed water flows smoothly to the outside, the opening height of the connection hole and the arrangement of the connection pipe have higher requirements, for example, the arrangement of the connection pipe should be installed lower than the bottom of the air conditioner indoor unit, and the opening of the connection hole should also be lower than the bottom of the air conditioner indoor unit. If the air conditioner indoor unit is not installed according to such requirements, the air conditioner will cause water accumulation inside the indoor space due to poor drainage. This makes the installation of the air conditioner more difficult. In addition, some existing embedded air conditioning solutions require the indoor unit of the air conditioner to be installed in a closed space such as a cabinet. The online pipe with a drainage pipe cannot be installed directly through the reserved hole in the wall like an ordinary wall mounted unit. It is often necessary to reserve a certain amount of expansion to ensure convenient installation and maintenance. Since the embedded air conditioner is designed for aesthetics, the online pipe with a certain amount of expansion will be reserved in the cabinet, but the space in the cabinet is limited, and the online pipe with a certain amount of expansion may be placed higher than the bottom of the indoor unit of the air conditioner, which will lead to poor drainage of condensed water and water accumulation on the indoor floor.

[0074] Combine the following Figures 1 to 29 The air conditioner indoor unit of this embodiment will be described in detail.

[0075] 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 delivery pipe 220 . The shell 110 includes a base 111, and a water receiving trough 1111 is arranged 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.

[0076] Since the air conditioner indoor unit 100 of this embodiment is additionally provided with a drain pipe and a drain pump 210, and the water supply pipe section 221 with the highest horizontal height of the drain pipe is set to be higher than the part with the lowest horizontal height of the water receiving tank, and the drain 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 to the outside will be raised, and the raised condensed water will then flow out to the outside by gravity, and then 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, the present embodiment can reduce the difficulty of installing the air conditioner, and ensure the flow field of the condensed water when the air conditioner indoor unit is reserved with a certain amount of expansion and contraction of the connection pipe.

[0077] Reference Figure 2 and Figure 5 In the present 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 disposed close to the top of the base 111 .

[0078] It is understandable 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 a certain amount of expansion and contraction of the online pipe is reserved for the indoor unit of the air conditioner (for example, when the indoor unit 100 of the air conditioner is embedded).

[0079] Reference Figure 2 and Figure 3 In this embodiment, a volute cavity 1112 is provided at the front side of the base 111, and the volute cavity 1112 is used to set the indoor fan 130 of the air conditioner indoor unit 100; and the water receiving tank 1111 includes a first water tank 1111a and a second water tank 1111b connected to the first water tank 1111a, and the first water tank 1111a is located behind the volute cavity 1112, and the second water tank 1111b is located in front of the volute cavity 1112, and the level of the second water tank 1111b is lower than that of the first water tank 1111a. Therefore, the water receiving tank 1111 can completely receive the condensed water flowing down from the indoor heat exchanger 120 and realize the drainage of the water receiving tank 1111.

[0080] 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.

[0081] 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 close to the top of the base 111 can be set 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 the flow field for discharging condensed water when a certain amount of telescopic online pipe is reserved for the indoor unit of the air conditioner (for example, when the indoor unit 100 of the air conditioner is embedded).

[0082] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, the water delivery pipe 220 includes an extension section 222 and a water delivery 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 delivery section 223, the second end of the water delivery section 223 extends horizontally toward the outside of the base 111, and the second end of the water delivery section 223 is used to connect to the drainage pipe; and the water supply pipe section 221 includes the water delivery section 223 and its connection with the extension section 222.

[0083] It is understandable that by setting the extension section 222, the water pipe 220 can have a water supply pipe section 221 as high as possible and occupy a very small space in the shell 110, and the setting of the second end of the water supply section 223 extending horizontally toward the outside of the base 111 can facilitate communication with the drain pipe.

[0084] 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 .

[0085] It should be understood that by bending and winding the water pipe 220, and arranging the bent and wound water pipe 220 in the vertical direction, the water pipe 220 has a higher water supply pipe section 221. In addition, the end of the water pipe 220 connected to the drain pipe can be arranged at the position where the drain pipe is arranged in the original shell 110, avoiding the need to re-open the mold of the shell 110, and reducing the production cost of the air conditioner indoor unit 100 of this modified embodiment. And by arranging the end of the water pipe 220 connected to the drain pipe toward the outside of the base 111, it can be convenient to communicate with the drain pipe.

[0086] Reference Figure 3 , Figure 4 and Figure 5 In 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, and the water pipe 220 is passed through the fixing hole to ensure the stability of the water pipe 220.

[0087] In addition, in the prior art, the internal structure of the air conditioner indoor unit 100 is compact, especially in the front side of the base 111, and the space utilization rate is extremely high. If the drain pump 210 is to be set in the second water tank 1111b or in the front side of the base 111, the base 111 may need to be re-molded, which will increase the production cost of the air conditioner indoor unit 100. In addition, the water storage space of the water tank 1111 is small, and the drain pump 210 is frequently started and stopped, which greatly reduces the service life of the drain pump 210.

[0088] Furthermore, the position where the fixing plate 1113 fixes the water pipe 220 may be the extension section 222 .

[0089] Reference Figure 3 and Figure 5 In the present 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, and a water receiving space 231 connected to the water receiving tank 1111 is provided inside the water receiving device 230, and 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.

[0090] It is understandable that the existing wall-mounted air conditioner indoor unit 100 forms an unused space (placement cavity 1114) behind the base 111, and the space for storing condensed water in the air conditioner indoor unit 100 can be increased by adding a water receiving device 230, so as to reduce the number of starts and stops of the drain pump 210 and ensure the service life of the drain pump 210. In addition, by arranging the water receiving device 230 in the placement cavity 1114 and arranging the drain pump 210 in the water receiving space 231, the utilization rate of the internal space of the housing 110 is improved, and the base 111 is avoided from being re-molded, thereby effectively controlling the production cost of the air conditioner indoor unit 100.

[0091] Reference Figure 2 , Figure 3 , Figure 5 and Figure 6 In this embodiment, the water receiving space 231 has a lower level than the water receiving tank 1111; and the air conditioner indoor unit 100 further includes a drainage pipe 240. The first end of the drainage pipe 240 is connected to the water receiving space 231 toward the rear and downward, and the second end of the drainage pipe 240 is connected to the lowest part of the water receiving tank 1111 toward the front and upward.

[0092] 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 to be further discharged smoothly.

[0093] Furthermore, the drainage pipe 240 may include a first pipe body 241 connected to the lowest portion of the water receiving tank 1111 and a second pipe body 242 connected to the water receiving space 231, and the first pipe body 241 and the second pipe body 242 are connected to each other. This facilitates the installation and removal of the water receiving device 230 from the base 111 (and / or the water receiving tank 1111).

[0094] 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). Similarly, the condensed water in the water tank can be discharged into the water receiving device 230.

[0095] Reference Figure 2 and Figure 5In the present 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.

[0096] Reference Figure 3 and Figure 5 In this embodiment, the number of the 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 flowing into the water receiving device 230.

[0097] 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 opened upward on the water receiving tray. This ensures that the water receiving device 230 can store condensed water while ensuring that the air conditioner indoor unit 100 has a lower production cost as much as possible.

[0098] In a modified embodiment, the water receiving device 230 is a water receiving box, and the water receiving space 231 is a cavity in the water receiving box. This ensures that the water receiving device 230 can store condensed water while preventing dust and other debris from falling into the water receiving space 231, so as to prevent the water pump from being blocked and ensure the service life of the water pump. In addition, if the condensed water in the water receiving space 231 does not reach the preset drainage height value for a long time, the condensed water in the water receiving space 231 may have an odor, and the setting of the water receiving box can prevent the odor from being emitted to the indoor space 330, thereby ensuring user experience.

[0099] 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 in the water receiving device 230 and is used to detect the height of the water in the water receiving space 231; and the drainage pump 210 is used to start when the height of the water in the water receiving space 231 is greater than a preset value and pump the water in the water receiving space 231 into the water supply pipe section 221. This realizes the automatic discharge of condensed water and ensures user experience.

[0100] In addition, in the prior art, although the solution of embedding the air conditioner in the 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 hole in the prior art will still be exposed to the indoor space 330, affecting the overall aesthetics.

[0101] Reference Figure 7 and Figure 8 In this embodiment, the air conditioner indoor unit 100 is used to be embedded in 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.

[0102] It is understandable that when the cabinet 310 is small as a whole and the air conditioner indoor unit 100 can be embedded in it for installation, if the cabinet 310 is to be covered on the online hole to ensure the aesthetics of the indoor space 330, the online hole is very likely to be opened to a position higher than the bottom of the air conditioner indoor unit 100. Furthermore, through the settings in the above embodiments of the present application, the online hole can be opened at the height on the wall 320 corresponding to any position lower than the water supply pipe section 221 and higher than the bottom of the air conditioner indoor unit 100, and the smoothness of the discharge of condensed water by the air conditioner indoor unit 100 can be ensured. Therefore, when the air conditioner indoor unit 100 of this embodiment adopts the embedded installation solution, the aesthetics of the indoor space 330 and the smoothness of the discharge of condensed water can be greatly ensured.

[0103] In addition, it can be seen from the above that 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 completely exposed in the indoor space 330, which will lead to poor consistency and aesthetics of the air-conditioning indoor unit 100, other household appliances and the cabinets placed in the indoor space 330. Therefore, the installation method in which the air-conditioning indoor unit 100 is embedded in the cabinet can be selected. At present, in the prior art, in some embedded methods, the air-conditioning indoor unit 100 will be directly placed in the embedded space of the cabinet and 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 left and right direction, after a long time, the bottom plate of the cabinet will be bent and deformed in the middle to bend downward, which greatly reduces the overall aesthetics of the embedded installation of the air-conditioning indoor unit 100.

[0104] Reference Figure 1 , Figure 7 and Figure 8In the first implementation of the present embodiment, the air conditioner 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 opening 3111 facing forward; and the air conditioner indoor unit 100 includes a plurality of legs 410. The housing 110 is used to be arranged in the installation cavity 311, and the front side of the housing 110 is arranged forward through the cavity opening 3111; the plurality of legs 410 are arranged at the bottom of the housing 110, and the plurality of legs 410 are distributed near the left and right ends of the housing 110, and the plurality of legs 410 are used to distribute the gravity of the air conditioner indoor unit 100 to the left and right sides of the bottom wall of the installation cavity 311 when the air conditioner indoor unit 100 is supported on the bottom wall of the installation cavity 311.

[0105] Since the air conditioner indoor unit 100 of this embodiment is provided with a plurality of legs 410 at the bottom of the housing 110, and the plurality of legs 410 are distributed near the left and right ends of the housing 110, when the air conditioner indoor unit 100 is embedded in the cabinet 310, the plurality of legs 410 can distribute the overall weight of the air conditioner indoor unit 100 to the left and right ends of the bottom plate of the cabinet 310. Therefore, this embodiment can effectively prevent the bottom plate of the cabinet from being bent and deformed downward in the middle when the air conditioner indoor unit 100 is embedded in the cabinet, thereby greatly ensuring the overall aesthetics of the embedded installation of the air conditioner indoor unit 100.

[0106] 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.

[0107] It can be understood that setting the support foot 410 to be a truncated cone with an end surface area at the bottom that is smaller than the cross-sectional area of ​​the support foot 410 close to the shell 110 can ensure the connection stability between the support foot 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 ensure the distribution effect of multiple supports 410 in distributing the overall weight of the air-conditioning indoor unit 100 to the left and right ends of the bottom plate of the cabinet 310.

[0108] Reference Figure 1 , Figure 8 and Fig.11 In this embodiment, the shell 110 includes a cover shell 112, the base 111 is disposed in the cover shell 112, and the cover shell 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 disposed at the bottom of the cover shell 112.

[0109] 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 the gravity of the air-conditioning indoor unit 100 is ultimately borne by the cover 112, so that the support foot 410 can be set at the bottom of the cover 112.

[0110] In some other embodiments, the cover 112 covers the front side of the base 111, and the cover 112 wraps the front side and the 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.

[0111] Furthermore, it should be understood that most of the heavier working parts 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 .

[0112] 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 shell 110, and the support leg 410 and the shell 110 are an integrated structure.

[0113] 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, and the stability of the air-conditioning indoor unit 100 embedded in the interior of the cabinet 310 can be further ensured.

[0114] 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 foot 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 foot 410 can be an integrated structure with the base 111, or the support foot 410 is an integrated structure with the base 111 and the cover shell 112.

[0115] Reference Fig. 9 In this embodiment, the number of the legs 410 is four, 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 .

[0116] 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 feet 410 can all be set at the bottom of the cover shell 112; when the cover shell 112 is wrapped around the front side and top side of the base 111, the four feet 410 can be arranged in pairs at the bottom of the cover shell 112 and the bottom of the base 111 respectively.

[0117] Reference Fig.10 In the modified embodiment, the number of the legs 410 is two, and each leg 410 is extended along 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 embedded in the cabinet 310.

[0118] 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 feet 410 can be both set at the bottom of the cover shell 112, and each foot 410 can be arranged in the front and back directions; when the cover shell 112 is wrapped around the front side and top side of the base 111, the two feet 410 can be both connected to the bottom of the base 111, and each foot 410 can extend forward to the bottom of the cover shell 112.

[0119] In addition, in the prior art, the air conditioner indoor unit 100 is directly placed in the embedded space of the cabinet and on the bottom plate of the cabinet, so that the height of the air conditioner indoor unit 100 cannot be adjusted. If a certain part of the air conditioner indoor unit 100 is too high or too low, and the housing 110 is tilted, the air conditioner indoor unit 100 will be unstable when placed in the embedded space. Even when the air outlet height of the air conditioner indoor unit 100 is not suitable, the air outlet direction cannot meet the needs of the user, which will greatly reduce the user experience.

[0120] Reference Figure 7 and Fig.12 In the second implementation of the present embodiment, the air conditioner 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 opening 3111 facing forward; and the air conditioner indoor unit 100 includes a plurality of legs 410 and a plurality of telescopic structures 420. The housing 110 is used to be arranged in the installation cavity 311; the plurality of legs 410 are arranged at the bottom of the housing 110; each telescopic structure 420 is telescopically arranged between the bottom of the housing 110 and the corresponding leg 410, and the plurality of telescopic structures 420 are used to adjust the height of at least part of the structure of the housing 110 in the installation cavity 311.

[0121] Since the air conditioner indoor unit 100 of this embodiment is provided with multiple telescopic structures 420 corresponding to the bottom of the multiple legs 410 and the housing 110, the multiple telescopic structures 420 are used to adjust the height of at least part of the structure of the housing 110 in the installation cavity 311, and thus the height of part or the whole of the air conditioner can be adjusted. When the air conditioner indoor unit 100 is embedded in the cabinet 310, if the height of part of the housing 110 is too high or too low, it can be adjusted by a single telescopic structure 420 to level the air conditioner indoor unit 100 as a whole; if the height of the air outlet of the air conditioner indoor unit 100 (which can be located on the front side of the housing 110) does not meet the user's air outlet requirements, the height of the air outlet of the air conditioner indoor unit 100 can be adjusted by multiple telescopic structures 420. Therefore, this embodiment can ensure the stability of the air conditioner indoor unit 100 when embedded in the cabinet 310, and ensure the user's experience.

[0122] Reference Fig.12 In this embodiment, a threaded hole is provided at the bottom of the housing 110 corresponding to the position of the supporting leg 410; and each telescopic structure 420 includes a screw rod 421. One end of the screw rod 421 is rotatably connected to the threaded hole, and the other end of the screw rod 421 is connected to the supporting leg 410. Thus, the telescopic structure 420 can be extended and retracted.

[0123] In a modified embodiment, the telescopic structure 420 may 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 telescoped in the same manner.

[0124] In this embodiment, the material of the support leg 410 is rubber.

[0125] It is understandable that by setting the support foot 410 to be made of rubber material to provide a shock-absorbing effect for the air-conditioning indoor unit 100, the noise of the air-conditioning indoor unit 100 during operation can be greatly reduced, and the user experience can be improved. In addition, since the friction coefficient of rubber is relatively large, the friction force of the support foot 410 when contacting the bottom wall of the installation cavity can be ensured, thereby ensuring the stability of the air-conditioning indoor unit 100 when embedded in the cabinet 310.

[0126] Reference Fig.12 and Fig.13 In this embodiment, the support leg 410 is in a round shape, so that the contact area between the support leg 410 and the bottom wall of the installation cavity can be ensured, so as to ensure the stability of the air conditioner indoor unit 100 when it is embedded in the cabinet 310.

[0127] Reference Fig.11 , Fig.12 and Fig.13In this embodiment, the shell 110 includes a cover shell 112, the base 111 is disposed in the cover shell 112, and the cover shell 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 disposed at the bottom of the cover shell 112.

[0128] 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 the gravity of the air-conditioning indoor unit 100 is ultimately borne by the cover 112, so that the support foot 410 can be set at the bottom of the cover 112.

[0129] In some other embodiments, the cover 112 covers the front side of the base 111, and the cover 112 wraps the front side and the 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.

[0130] It should be understood that most of the heavier working parts of the air-conditioning indoor unit 100 (for example, the indoor heat exchanger, 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.

[0131] Reference Fig.12 In this embodiment, the front side surface of the shell 110 is arranged 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.

[0132] Since the air conditioner indoor unit 100 of this embodiment has a plurality of legs 410 distributed near the left and right ends of the housing 110, when the air conditioner indoor unit 100 is embedded in the cabinet 310, the plurality of legs 410 can distribute the overall weight of the air conditioner indoor unit 100 to the left and right ends of the bottom plate of the cabinet 310. Therefore, this embodiment can effectively prevent the bottom plate of the cabinet from being bent and deformed downward in the middle when the air conditioner indoor unit 100 is embedded in the cabinet, thereby greatly ensuring the overall aesthetics of the embedded installation of the air conditioner indoor unit 100.

[0133] Reference Fig.13 In this embodiment, the number of the legs 410 is four, 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 .

[0134] 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 feet 410 can all be set at the bottom of the cover shell 112; when the cover shell 112 is wrapped around the front side and top side of the base 111, the four feet 410 can be arranged in pairs at the bottom of the cover shell 112 and the bottom of the base 111 respectively.

[0135] Reference Fig.14 In the modified embodiment, the number of the legs 410 is two, and each leg 410 is extended along 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 embedded in the cabinet 310.

[0136] 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 feet 410 can be both set at the bottom of the cover shell 112, and each foot 410 can be arranged in the front and back directions; when the cover shell 112 is wrapped around the front side and top side of the base 111, the two feet 410 can be both connected to the bottom of the base 111, and each foot 410 can extend forward to the bottom of the cover shell 112.

[0137] Reference Figure 7 and Fig.15 In the third implementation of the present embodiment, the air conditioner 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 opening forward; and the air conditioner indoor unit 100 includes a plurality of brackets 430. The housing 110 is used to be arranged in the installation cavity 311, and the front side of the housing 110 is arranged forward through the cavity 3111; the plurality of brackets 430 are used to be arranged on the left side wall 3113 and the right side wall 3114 of the installation cavity 311, and the plurality of brackets 430 are connected to the left and right ends of the housing 110 to distribute the gravity of the air conditioner indoor unit 100 to the left side wall 3113 and the right side wall 3114.

[0138] Since the air conditioner indoor unit 100 of this embodiment is additionally provided with a plurality of brackets 430, when the air conditioner indoor unit 100 is embedded in the cabinet 310, the plurality of brackets 430 are used to be arranged on the left side wall 3113 and the right side wall 3114 of the installation cavity 311, and the plurality of brackets 430 are connected to the left and right ends of the housing 110 to distribute the gravity of the air conditioner indoor unit 100 to the left side wall 3113 and the right side wall 3114. Therefore, this embodiment can effectively prevent the bottom plate of the cabinet from being bent and deformed downward in the middle when the air conditioner indoor unit 100 is embedded in the cabinet, thereby greatly ensuring the overall aesthetics of the embedded installation of the air conditioner indoor unit 100.

[0139] 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.

[0140] Reference Fig.15 In this embodiment, each bracket 430 includes a first plate 431 and a second plate 432. The first plate 431 is used to be attached to the left side wall 3113 / 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 is horizontally extended to the inside of the installation cavity 311, and the housing 110 is placed on the second plate 432.

[0141] It can be understood that the L-shaped bracket 430 formed by the first plate 431 and the second plate 432, while being connected to the left side wall 3113 and the left end of the shell 110 / 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.

[0142] Furthermore, the first plate 431 may be connected to the left side wall 3113 / right side wall 3114 by means of fasteners such as screws.

[0143] In addition, the second plate 432 may also be connected to the bottom of the housing 110 by means of fasteners such as screws, so as to ensure the connection stability between the bracket 430 and the air conditioner indoor unit 100 .

[0144] Reference Fig.11 and Fig.15 In this embodiment, the shell 110 includes a cover shell 112, the base 111 is disposed in the cover shell 112, and the cover shell 112 wraps around the front side, top side, bottom side, left side and right side of the base 111, and the bracket 430 is disposed at the bottom of the cover shell 112.

[0145] 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 the gravity of the air-conditioning indoor unit 100 is ultimately borne by the cover 112, and the bottom of the cover 112 can be set on the second plate 432 of the bracket 430.

[0146] In some other embodiments, the cover 112 covers the front side of the base 111 and wraps the front side and the 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.

[0147] It should be understood that most of the heavier working parts of the air-conditioning indoor unit 100 (for example, the indoor heat exchanger, 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.

[0148] Reference Fig.16 In this embodiment, there are four brackets 430, which are respectively arranged on the left side wall 3113 and the right side wall 3114 of the installation cavity 311, and the four brackets 430 are respectively arranged near the four corners of the bottom of the housing 110. This further ensures the stability of the air conditioner indoor unit 100 embedded in the cabinet 310.

[0149] 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.

[0150] Reference Fig.17 In the modified embodiment, the number of the brackets 430 is two, and each bracket 430 is extended along the front-to-back direction at the bottom of the housing 110. Similarly, the air conditioner indoor unit 100 can be placed on the bottom wall of the installation cavity 311, and the stability of the air conditioner indoor unit 100 embedded in the cabinet 310 is ensured.

[0151] Furthermore, 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.

[0152] In addition, currently, in the prior art, the wall-mounted air conditioner indoor unit 100 is installed on the wall of the indoor space 330 by drilling holes, fixing the mounting plate on the wall through expansion bolts and expansion holes, and then hanging the wall-mounted air conditioner indoor unit 100 on the mounting plate through the hanging parts set behind the wall-mounted air conditioner indoor unit 100, so as to be hung on the wall as a whole. However, such an installation method will inevitably cause the top of the wall-mounted air conditioner indoor unit 100 to tilt forward because the center of gravity of the wall-mounted air conditioner indoor unit 100 is located in front of the mounting plate, and there are mounting plates, hanging parts and other components between the back of the wall-mounted air conditioner indoor unit 100 and the wall 320. When the distance between the top of the air-conditioning indoor unit 100 and the ceiling 331 of the indoor space 330 is reserved to be small, the rear end of the top of the air-conditioning indoor unit 100 will touch the ceiling 331 of the indoor space 330, resulting in a gap, which reduces the space between the top of the air-conditioning indoor unit 100 and the ceiling 331, affecting the air intake of the air-conditioning indoor unit 100 and the working performance of the heating, cooling and other modes. In addition, after a long period of use, when the air-conditioning indoor unit 100 is mounted on the wall using expansion screws and expansion holes, the expansion holes on the wall will be expanded downward due to the downward gravity of the air-conditioning indoor unit 100, and the friction between the expansion screws and the expansion holes will decrease, causing the expansion screws to loosen. Under the gravity of the tilted air-conditioning indoor unit 100, the entire indoor unit will fall, which will lead to the appearance of safety problems.

[0153] Reference Fig.18 , Fig. 20 , Fig.21 or Fig. 22 ,as well as Fig.19 In the fourth implementation of the present embodiment, the air conditioner indoor unit 100 includes a hoisting device 500, and the hoisting device 500 is used to hoist the air conditioner indoor unit 100 in 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, and 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.

[0154] Reference Fig.18 or Fig.21In 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 forward tilting of the bottom end of the air-conditioning indoor unit 100 by its own gravity.

[0155] Since the air conditioner 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 conditioner indoor unit 100 in the installation space 340. Specifically, the hanging device 500 includes a hanger 520 and a hook 510, the hanger 520 is installed 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, and the first connecting plate 511 of the hanging plate is arranged at the top of the shell 110 near the front end of the shell 110, so that the center of gravity of the air conditioner indoor unit 100 as a whole is located behind the hanger 520, and the top end of the first connecting plate 511 extends upward to touch the top wall 341 of the installation space 340, so that the first connecting plate 511 can limit the air conditioner indoor unit 100 from tilting forward at its bottom end by its own gravity, so as to effectively avoid the appearance of the flash gap and avoid the reduction of the space between the top of the air conditioner indoor unit 100 and the top wall 341 of the installation space 340. 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, due to the effect of the first connecting plate 511, the force of the air-conditioning indoor unit 100 on the bracket 520 will always be vertically downward, and the expansion hole will not be expanded by the gravity of the air-conditioning indoor unit 100. The friction between the expansion bolts and the expansion hole can be well guaranteed, thereby effectively avoiding the air-conditioning indoor unit 100 from falling. Therefore, the hoisting device 500 of this embodiment can ensure the air intake and working performance of the air-conditioning indoor unit 100, and greatly ensure the installation stability and use safety of the air-conditioning indoor unit 100 in the installation space 340.

[0156] Furthermore, 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 backwards, 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.

[0157] Reference Fig. 20 and Fig. 22In the second application mode of the hanging device 500 of this embodiment, the first connecting plate 511 can be used to be arranged near the rear end of the housing 110, and the first side surface 5111 can be used to be arranged forward, so as to cause the first connecting plate 511 to limit the air-conditioning indoor unit 100 from tilting its bottom end backward by its own gravity. Based on the same reasons as the first embodiment of the hanging device 500, this embodiment can also effectively avoid the occurrence of flashing seams, avoid 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 avoid the air-conditioning indoor unit 100 from falling. Furthermore, the hanging device 500 of this embodiment can ensure the air intake and working performance of the air-conditioning indoor unit 100, and greatly ensure the installation stability and use safety of the air-conditioning indoor unit 100 in the installation space 340.

[0158] 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.

[0159] Reference Fig.18 In this embodiment, the height H of the first connecting plate 511 in the vertical direction is equal to the width K of the bracket 520 in the vertical direction. 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 .

[0160] Reference Fig. 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 conditioner indoor unit 100, and further ensures the air intake and working performance of the air conditioner indoor unit 100.

[0161] Reference Fig.18 and Fig. 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.

[0162] Reference Fig.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 backward, 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.

[0163] 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 conditioner indoor unit 100 can be made very flat, thereby ensuring the aesthetics of the air conditioner indoor unit 100.

[0164] Reference Fig.18 , Fig. 20 , Fig.21 and Fig. 22 In this embodiment, the housing 110 and the hook 510 are an integrated structure.

[0165] It is understandable that by setting 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, so as to further ensure the stability of the air conditioner indoor unit 100 when installed in the installation space 340 .

[0166] In this embodiment, the shell 110 includes a cover shell 112, the base 111 is arranged in the cover shell 112, and the cover shell 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 shell 112 are an integrated structure.

[0167] It is understandable 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 the gravity of the air-conditioning indoor unit 100 is ultimately borne by the cover 112, and the hook 510 is then connected to the cover 112. The hook 510 and the cover 112 are set as an integrated structure to further ensure the stability of the air-conditioning indoor unit 100 when installed in the installation space 340.

[0168] In some other embodiments, the cover 112 covers the front side of the base 111 and wraps the front side and the 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. The hook 510 is disposed on the base 111, and the hook 510 and the base 111 are an integrated structure.

[0169] It should be understood that most of the heavy working parts of the air conditioner indoor unit 100 (for example, the indoor heat exchanger, the indoor fan) are arranged on the base, and then the base 111 bears most of the weight of the air conditioner indoor unit 100. Then, the first connecting plate 511 can be used to be arranged near the rear end of the housing 110, and the first side surface 5111 can be used to be arranged forward, and the hook 510 can be arranged on the base to ensure the installation of the air conditioner indoor unit 100 and the stability of the installation space 340. In addition, the hook 510 and the base 111 are arranged as an integrated structure to further ensure the installation of the air conditioner indoor unit 100 and the stability of the installation space 340.

[0170] Reference Fig.19 In this embodiment, the rack 520 includes a base plate 522, a first hanging plate 523, and a second hanging plate 524. The base plate 522 is used to be 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 groove 521 is located between the base plate 522, the first hanging plate 523, and the second hanging plate 524. In this way, the hanging groove 521 is opened and the rack 520 is set. In addition, the base plate 522 and the second hanging plate 524 extend in the front-to-back direction, and the first hanging plate 523 extends in the up-down direction.

[0171] In a modified embodiment, the hanger 520 may be a block-shaped structure, and the hanger groove 521 is formed from the outside of the block-shaped structure to the inside thereof.

[0172] Reference Fig.23 In this embodiment, the base plate 522 is provided with first mounting holes 5221 arranged in the up and down directions, the first mounting hole 5221 is connected with a connecting member 5222, 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 to the first mounting hole 5221 and the top wall 341.

[0173] It is understandable that the opening of the first mounting hole 5221 facilitates the installer to fix the bracket 520 on the top wall 341 of the mounting space 340 through the connector 5222, thereby facilitating the installer to install the air conditioner indoor unit 100. In addition, the connector 5222 may be a fixing member such as an expansion bolt, a screw nut, etc.

[0174] Reference Fig.23 In this embodiment, the number of the first mounting holes 5221 is multiple, and the multiple first mounting holes 5221 are opened on the base plate 522 along the left-right direction to ensure the connection stability between the bracket 520 and the top wall 341 of the installation space 340, and further ensure the use safety of the air conditioner indoor unit 100.

[0175] In this embodiment, the number of the hangers 520 and the hooks 510 are both set to multiple, 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 use safety of the air conditioner indoor unit 100.

[0176] Reference Fig.23 In this embodiment, the hanging groove 521 is connected to the left and right ends of the hanging bracket 520.

[0177] 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.

[0178] Reference Fig.18 and Fig. 20 In this embodiment, the installation space 340 is the indoor space 330 , and the top wall 341 is the ceiling 331 .

[0179] It can be understood that the air-conditioning indoor unit 100 of this embodiment can be a wall-mounted air-conditioning indoor unit 100 in the prior art that adopts a hoisting manner.

[0180] Reference Fig.21 and Fig. 22 In this embodiment, the air conditioner 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 a top plate 3112 of the cabinet 310 that forms the installation cavity 311; and the front side surface of the shell 110 is arranged forward through the cavity 3111.

[0181] It is understandable that the air conditioner indoor unit 100 of this embodiment can also be embeddedly installed inside the cabinet by hoisting on the top plate 3112 of the cabinet body 310, thereby preventing the middle part of the bottom plate of the cabinet from being bent. Therefore, the hoisting device 500 of this embodiment can ensure the air intake and working performance of the air conditioner indoor unit 100, and greatly ensure the installation stability and use safety of the air conditioner indoor unit 100 in the installation cavity 311, and can effectively prevent the bottom plate of the cabinet from being bent and deformed downward in the middle when the air conditioner indoor unit 100 is embedded in the cabinet, thereby greatly ensuring the overall aesthetics of the embedded installation of the air conditioner indoor unit 100.

[0182] It should also be noted that, regardless of whether the air-conditioning indoor unit 100 is hoisted in the indoor space 330 by 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 a 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.

[0183] In addition, in the prior art, the air conditioner is usually provided with an openable and closable cabinet door 350 on the embedded cabinet. When the air conditioner is started, the user can open the cabinet door 350, and when the air conditioner is turned off, the user can close the cabinet door 350. However, the user needs to open or close the cabinet door 350 by himself every time, which brings great inconvenience to the user and reduces the user's experience.

[0184] Reference Figure 7 , Fig.24 and Fig.26 In this embodiment, the air conditioner indoor unit 100 is used to be embeddedly installed inside the cabinet 310, the cabinet 310 has an installation cavity 311 with a cavity 3111 opened forward, and a cabinet door 350 for opening or closing the cavity 3111 is rotatably connected to the cabinet 310; and the air conditioner indoor unit 100 includes a telescopic rod 610. The housing 110 is used to be arranged in the installation cavity 311, and the front side of the housing 110 is arranged forward through the cavity 3111; 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 be connected to the cabinet door 350. The telescopic rod 610 is used to extend and cause the cabinet door 350 to open when the air conditioner indoor unit 100 receives a first preset instruction, and shorten and cause the cabinet door 350 to close when the air conditioner indoor unit 100 receives a second preset instruction.

[0185] 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, the telescopic end of the telescopic rod 610 is used to be connected to the cabinet door 350, and 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 instruction (for example, a power-on instruction), and shorten and cause the cabinet door 350 to close when the air conditioning indoor unit 100 receives a second preset instruction (for example, a power-off instruction). Furthermore, the air conditioning indoor unit 100 can open and close the cabinet door 350 without manpower. Therefore, after the air conditioning indoor unit 100 of this embodiment is embedded, the cabinet door 350 can be opened and closed without the user doing it himself, so as to improve the user experience.

[0186] 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-mentioned embodiment, the connection between the bracket 430 and the shell 110 can also be connected by means of 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.

[0187] In addition, when the indoor air conditioner 100 is damaged, the air conditioner may not be able to open the cabinet door 350 normally. Furthermore, if the connection between the telescopic end of the telescopic rod 610 and the cabinet door 350 is fixed or hinged, at this time, due to the effect of the telescopic rod 610, even if the user or maintenance personnel manually opens the cabinet door 350 to repair the indoor air conditioner 100, they may not be able to open the cabinet door 350 normally.

[0188] Reference Figure 7 , Fig.24 , Fig.25 and Fig.26 In this embodiment, the telescopic end of the telescopic rod 610 is used to contact the inner side of the cabinet door 350.

[0189] It should be understood that the connection between the telescopic end of the telescopic rod 610 and the cabinet door 350 is set to a contact connection. Then the air-conditioning indoor unit 100 can realize the push of the cabinet door 350 in a closed state to an open state through the telescopic rod 610. And when the cabinet door 350 is in a closed state, due to the contact connection between the telescopic end of the telescopic rod 610 and the cabinet door 350, when the air-conditioning indoor unit 100 cannot open the cabinet door 350 normally, the user or maintenance personnel can also open the air-conditioning indoor unit 100 manually.

[0190] Furthermore, when it is necessary to perform a power-off operation on the air conditioner indoor unit, such as described in the following embodiments, since the telescopic end of the telescopic rod 610 and the cabinet door 350 are not fixedly connected, 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 manually close the cabinet door 350 after power off. Furthermore, by setting the telescopic end of the telescopic rod 610 to contact the inner side of the cabinet door 350, it is possible to effectively avoid the situation where the user cannot open the cabinet door 350 due to the action of the telescopic rod 610 and the cabinet door 350 cannot be closed after the cabinet door 350 is opened to power off the air conditioner 100.

[0191] Reference Fig.25 In this embodiment, the air conditioner 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 and contact the inner side surface of the cabinet door 350 .

[0192] It can be understood that, through the setting of the rolling member 620, it can be ensured that when the telescopic rod 610 pushes open 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.

[0193] Reference Fig.25In this embodiment, the rolling member 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 .

[0194] 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.

[0195] 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.

[0196] 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 close the cabinet door 350 .

[0197] Reference Figure 7 , Fig.24 In the first implementation mode of closing the cabinet door 350 of the present embodiment, the cabinet door 350 is rotatably connected to the top of the cabinet body 310 .

[0198] It is understandable that, since the cabinet door 350 itself has gravity, when the telescopic end of the telescopic rod 610 is retracted, even if the connecting rope 630 is not provided, the cabinet door 350 can close the cavity 3111 by itself.

[0199] Reference Fig.24 and Fig.25 In the second implementation mode of closing the cabinet door 350 of the present embodiment, the air conditioner 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 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.

[0200] Furthermore, the connecting rope 630 may be a steel wire rope to ensure that the telescopic rod 610 can drive the cabinet door 350 when shortened. The connecting rope 630 may be a flexible connecting rope, for example, a rope body made of polymeric materials such as polyester fiber, to avoid the connecting rope 630 hindering the movement of the cabinet door when the telescopic rod 610 shortens and drives the cabinet door 350 to close.

[0201] Reference Fig.24 and Fig.25In this embodiment, the air conditioner indoor unit 100 further includes a first hanging ear 640 and a second hanging ear 650. The first hanging ear 640 is used to be arranged on the inner side of the cabinet door 350; the second hanging ear 650 is arranged at the telescopic end of the telescopic rod 610, and one end of the connecting rope 630 is connected to the second hanging ear 650, and the other end of the connecting rope 630 is connected to the first hanging ear 640.

[0202] It is understandable that, by providing the first lifting ear 640 and the second lifting ear 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.

[0203] In a modified implementation manner of closing the cabinet door 350 of the present 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.

[0204] It is understandable that, through the provision of 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 spring sheet, etc.

[0205] Reference Fig.24 and Fig. 27 In this embodiment, the telescopic end of the telescopic rod 610 is inclined toward the connection axis between the cabinet door 350 and the cabinet body 310 .

[0206] It should be understood that by tilting the telescopic end of the telescopic rod 610 toward the connecting axis of the cabinet door 350 and the cabinet body 310, the telescopic rod 610 can fully open the cabinet door 350 with a short telescopic stroke, and the power required to open the cabinet door 350 is small. In addition, the stability of the cabinet door 350 during the opening and closing process can be ensured.

[0207] Reference Fig.24 and Fig. 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 .

[0208] It is understandable that, since 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 set on the base 111 of the housing 110 to ensure the stability of the telescopic rod 610 in the process of starting the closing process of the cabinet door 350. In addition, the base 111 is a load-bearing component extending in the left and right directions, and thus, the base 111 can be compatible with more fixed parts and more fixing solutions, and thus the tail end of the telescopic rod 610 can be connected to the base 111.

[0209] In addition, the tail end of the telescopic rod 610 can also be connected to the inner wall of the cover 112. In this embodiment, the cover 112 can bear the gravity of the base 111, 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.

[0210] Reference Figure 7 , Fig.24 and Fig. 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.

[0211] It is understandable that, since the cabinet door 350 can be self-closed by its own gravity when it is rotatably connected to the top of the cabinet body 310, it can be implemented as a preferred embodiment. In addition, since the air conditioner indoor unit 100, an important component for cooling and heating, needs to be arranged in front of the base 111, the tail end of the telescopic rod 610 can be arranged close to the right end / left end of the base 111.

[0212] Reference Fig.24 In this embodiment, the telescopic rod 610 is an electric push rod 611 .

[0213] 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 provide an additional power source, thereby reducing the production cost of the air-conditioning indoor unit 100 .

[0214] In a modified embodiment, the telescopic rod 610 may also be a pneumatic push rod or a hydraulic push rod.

[0215] In a modified embodiment, a driving device is provided at the rear end of the telescopic rod 610, and the driving device is provided on the housing 110 (base 111), and the driving device is used to drive the telescopic rod 610 to rotate around the driving device, and the rotation direction of the telescopic rod 610 is the same as the opening or closing direction of the cabinet door 350. Thus, the stability of the telescopic rod 610 in the process of opening or closing the cabinet door 350 can be greatly guaranteed.

[0216] For example, when the cabinet door 350 is rotatably connected to the top of the cabinet body 310, the driving device can drive the telescopic end of the telescopic rod 610 to move in the up and down directions, and drive the telescopic rod 610 to rotate around the driving device. Specifically, when the cabinet door 350 is in a closed state, the telescopic end of the telescopic rod 610 is located at the bottom of the cabinet door 350, and as the telescopic rod 610 is extended, the cabinet door 350 is pushed open, and the telescopic end of the telescopic rod 610 moves upward accordingly; when the cabinet door 350 is in an open state, the telescopic end of the telescopic rod 610 is located near the rotation center axis of the cabinet door 350, and as the telescopic rod 610 is shortened, the cabinet door 350 is closed, and the telescopic end of the telescopic rod 610 moves downward accordingly. In this way, the stability of the telescopic rod 610 in the process of urging the cabinet door 350 to be opened or closed can be greatly guaranteed.

[0217] In addition, the air conditioner will encounter many situations where it needs to be powered off, such as inspection and maintenance, and in northern my country, the air conditioner will be plugged in for use when it is overheated in summer, and the air conditioner will be powered off in winter when there is heating. After the air conditioner indoor unit 100 is installed in the installation cavity 311 of the cabinet, since the space for installing the air conditioner indoor unit 100 in the cabinet is small, whether the socket is set on the rear wall, top wall 341, bottom wall or left and right side walls of the installation cavity 311 of the cabinet, it is very inconvenient to unplug the power plug 720 of the already plugged air conditioner indoor unit 100 again and power off the air conditioner, which in turn reduces the user's experience of using the air conditioner.
