Description

Technical Field

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

[0002] Air conditioners, appliances that provide cooling in the summer and warmth in the winter, are increasingly popular among consumers. Wall-mounted air conditioners, in particular, are particularly popular due to their high household suitability and are in huge demand on the market. Furthermore, with the advancement of science and technology, air conditioners are becoming increasingly versatile, offering features such as humidification and dehumidification in addition to conventional cooling and heating. At the same time, users are increasingly emphasizing the aesthetics of home appliances like air conditioners, and their integration with their home decor. To ensure the air conditioner blends seamlessly into their home living environment, users are installing the indoor unit of their wall-mounted air conditioner in a cabinet, leading to the emergence of flush-mounted air conditioners.

[0003] In existing air conditioner indoor units, when the indoor heat exchanger is in cooling mode, the cold energy from the indoor heat exchanger is transferred to the rear wall of the indoor unit housing. When the air in the space behind the indoor unit contacts the rear wall of the housing, a large amount of condensed water forms, which then adheres to the rear wall of the base. This condensed water accumulates even more on the rear side of the base when the air conditioner is in dehumidification mode. This condensed water cannot be cleaned, and because the space behind the air conditioner is small and air circulation is poor, condensed water can remain on the rear side of the housing for a long time. If the indoor unit is wall-mounted, the prolonged retention of condensed water can easily cause mold on the wall, creating an unpleasant odor in the room and even damaging the wall, significantly reducing its aesthetics and diminishing the user experience. If the indoor unit is built into a cabinet, the prolonged retention of condensed water can cause mold on the cabinet, creating an unpleasant odor in the room and even damaging the cabinet, diminishing its aesthetics and diminishing the user experience.

Figure 9 This is a second cross-sectional schematic diagram of an embedded air-conditioning indoor unit according to an embodiment of the present utility model; Figure 10 This is a third cross-sectional schematic diagram of an embedded air-conditioning indoor unit according to an embodiment of the present utility model.

[0057] Reference Figure 1 、 Figure 2 、 Figure 4 and Figure 5 In this embodiment, the embedded air-conditioning indoor unit is used to be embedded in the cabinet cavity 410 of the cabinet body 400. The embedded air-conditioning indoor unit includes a shell 100, an indoor heat exchanger 200 and an insulation layer 300.

[0058] The indoor heat exchanger 200 is disposed in the casing 100 .

[0059] The insulation layer 300 is arranged on the rear side wall of the shell 100, and the insulation layer 300 is arranged corresponding to the indoor heat exchanger 200. The insulation layer 300 is used to limit the heat exchange between the part of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the embedded air-conditioning indoor unit works.

[0060] Since an insulation layer 300 is provided on the rear side wall of the shell 100 of the embedded air-conditioning indoor unit of this embodiment, the insulation layer 300 is provided corresponding to the indoor heat exchanger 200, and the insulation layer 300 can limit the heat exchange between the part of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the embedded air-conditioning indoor unit works.

[0061] Furthermore, when the air conditioner operates in cooling mode or dehumidification mode, the cold energy exchanged by the indoor heat exchanger 200 to the rear wall of the shell 100 will not condense the water vapor in the air in the space behind the indoor unit, and no condensed water will precipitate from the rear wall of the shell 100, nor will any condensed water remain on the rear side of the shell 100 for a long time.

[0062] Therefore, this embodiment can effectively prevent the cabinet 400 from becoming moldy or damaged, avoid the appearance of moldy smell in the indoor space, and ensure the user experience of the embedded air conditioner indoor unit.

[0063] In this embodiment, the thermal insulation layer 300 includes one or more of foam material, thermal insulation cotton, vacuum panel and metal foil.

[0064] It can be understood that the insulation layer 300 can be one or more of foam material, insulation cotton, vacuum panel and metal foil, so that the insulation layer 300 can limit the heat exchange between the part of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the embedded air-conditioning indoor unit works, so that the insulation layer can play a role in keeping cold when the embedded air-conditioning is running in cooling mode or dehumidification mode.

[0065] Moreover, when the thermal insulation layer 300 is a foam material, the foam material can be directly sprayed on the corresponding position to realize the construction of the thermal insulation layer 300; when the thermal insulation layer 300 is thermal insulation cotton, it can be adhered to the corresponding position through a colloid to realize the connection between the thermal insulation layer 300 and the rear side wall of the shell 100; when the thermal insulation layer 300 is a vacuum panel, it can be connected to the corresponding position through a snap fastener to realize the connection between the thermal insulation layer 300 and the rear side wall of the shell 100.

[0066] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 6 In this embodiment, the housing 100 includes a base 110. The base 110 is extended in the left-right direction, and a volute 111 extending in the left-right direction is provided on the front side of the base 110. The volute 111 is used to accommodate the indoor fan of the air conditioner indoor unit.

[0067] The base 110 includes a rear plate 112 extending left and right. The rear plate 112 is located above the volute 111 and is arranged corresponding to the indoor heat exchanger 200 . The insulation layer 300 is arranged on the rear side of the rear plate 112 .

[0068] It can be understood that since the portion of the rear side wall of the shell 100 opposite to the indoor heat exchanger 200 is the rear side wall of the rear backboard 112, the insulation layer 300 can be specifically arranged on the rear side surface of the rear backboard 112 to achieve heat exchange between the portion of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the embedded air-conditioning indoor unit works.

[0069] Reference Figure 5 、 Figure 6 and Figure 7 In this embodiment, a connecting groove 113 is provided on the rear side wall of the base 110 , and a connecting protrusion 310 is provided on the side of the thermal insulation layer 300 facing the base 110 , and the connecting protrusion 310 is arranged in the connecting groove 113 .

[0070] It can be understood that by coordinating the connecting groove 113 and the connecting protrusion 310 , the contact area between the insulation layer 300 and the rear side of the base 110 can be increased, thereby ensuring the stability of the connection between the insulation layer 300 and the shell 100.

[0071] In addition, the connection protrusion 310 can be provided in the middle portion of the thermal insulation layer 300 in the up-down direction to effectively ensure the stability of the connection between the thermal insulation layer 300 and the shell 100 .

[0072] Furthermore, the number of the connecting grooves 113 and the connecting protrusions 310 can be set to be multiple accordingly to further ensure the stability of the connection between the thermal insulation layer 300 and the shell 100. The specific shapes of the connecting grooves 113 and the connecting protrusions 310 at different positions can be different.

[0073] Reference Figure 2 、 Figure 9 and Figure 10 In this embodiment, the indoor heat exchanger 200 is disposed on the base 110 , and the indoor heat exchanger 200 is located above the volute 111 .

[0074] The indoor heat exchanger 200 includes a first heat exchange section 210, which is arranged obliquely above and behind the indoor fan, and the bottom end of the first heat exchange section 210 is set toward the rear and bottom, and the rear support plate 112 is set corresponding to the bottom end of the first heat exchange section 210.

[0075] It is understandable that, because the distance between the bottom end of the first heat exchange section 210 and the rear sidewall of the housing 100 is the shortest, the portion of the rear sidewall of the housing 100 corresponding to the bottom end of the first heat exchange section 210 receives the most cooling energy. Consequently, the rear plate 112 can be positioned corresponding to the bottom end of the first heat exchange section 210, i.e., the insulation layer 300 can be positioned corresponding to the bottom end of the first heat exchange section 210, to effectively ensure the cooling performance of the insulation layer 300, effectively ensuring the insulation layer 300's ability to limit the release of condensed water from the rear side of the housing 100, and thus ensuring a better user experience.

[0076] Reference Figure 2 、 Figure 3 、 Figure 9 and Figure 10 In this embodiment, the base 110 is provided with an auxiliary water receiving tank 114 located below the first heat exchange section 210. The auxiliary water receiving tank 114 is used to receive the water flowing down from the first heat exchange section 210, and the rear support plate 112 is located above the auxiliary water receiving tank 114.

[0077] The bottom of the thermal insulation layer 300 extends to the bottom outer wall of the secondary water receiving tank 114 .

[0078] It should be understood that, in addition to the situation where the cold energy on the indoor heat exchanger 200 is directly exchanged to the rear wall of the shell 100, when the air conditioner is running in cooling mode / dehumidification mode, a large amount of condensed water will be precipitated from the indoor heat exchanger 200, and these condensed water will fall into the auxiliary water tank 114. The condensed water will bring the cold energy of the indoor heat exchanger 200 to the auxiliary water tank 114, and then cause condensed water to adhere to the outer wall of the shell 100 to form the auxiliary water tank 114.

[0079] Furthermore, extending the insulation layer 300 to the bottom outer wall of the auxiliary water tank 114 can limit heat exchange between the bottom outer wall of the auxiliary water tank 114 and the air behind the indoor unit, thus limiting the formation of condensation on the rear outer wall of the auxiliary water tank 114. This further prevents the cabinet 400 from becoming moldy or damaged, and avoids the presence of moldy odors in the indoor space, further enhancing the user experience of the built-in air conditioner indoor unit.

[0080] Reference Figure 2 、 Figure 6 、 Figure 9 and Figure 10 In this embodiment, the rear side wall of the base 110 is connected to a rear water receiving plate 115 extending toward the rear and upper part, and a rear water receiving groove 116 is formed between the rear water receiving plate 115 and the rear wall of the base 110, and the rear water receiving groove 116 is located below the rear backing plate 112, and the insulation layer 300 is arranged above the rear water receiving plate 115.

[0081] The rear water tank 116 is connected to the drain pipe of the embedded air conditioner indoor unit.

[0082] It is understood that even if condensed water precipitates on the rear sidewall of the housing 100, it will fall into the rear water tank 116 and then be discharged to the outdoor space through the drain pipe, thus preventing the condensed water from being retained on the rear side of the housing 100 for a long time. Furthermore, the provision of the rear water tank 116 can further prevent the cabinet 400 from becoming moldy or damaged, and avoid the presence of moldy odors in the indoor space, further ensuring the user experience of the embedded air conditioner indoor unit.

[0083] Furthermore, since the thermal insulation layer 300 is disposed on the rear water receiving plate 115, the contact area between the housing 100 and the thermal insulation layer 300 is increased, and the rear water receiving plate 115 can bear at least part of the weight of the thermal insulation layer 300. Therefore, the aforementioned arrangement of the rear water receiving plate 115 can further ensure the stability of the connection between the thermal insulation layer 300 and the housing 100.

[0084] Reference Figure 2 、 Figure 3 、 Figure 9 and Figure 10In this embodiment, the indoor heat exchanger 200 further includes a second heat exchange section 220 and a third heat exchange section 230 . The second heat exchange section 220 is arranged obliquely above and in front of the indoor fan, and the third heat exchange section 230 is connected to the bottom of the second heat exchange section 220 .

[0085] A main water receiving tank 117 is also provided on the base 110 . The main water receiving tank 117 is located below the third heat exchange section 230 . The main water receiving tank 117 is used to receive water flowing down from the second heat exchange section 220 and the third heat exchange section 230 .

[0086] It can be understood that, by providing the main water receiving tank 117 , condensed water can be prevented from falling onto the floor of the indoor space, thereby ensuring that the floor of the indoor space is dry and clean, and ensuring the user experience.

[0087] Reference Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 In this embodiment, a water diversion channel 118 is provided on the base 110. The front end of the water diversion channel 118 is connected to the main water receiving tank 117, and the rear end of the water diversion channel 118 is connected to the rear water receiving tank 116 through the connecting port 119. The drain pipe is connected to the main water receiving tank 117, and the rear water receiving tank 116 is higher than the horizontal height of the main water receiving tank 117.

[0088] It can be understood that the condensed water in the rear water tank 116 can flow into the main water tank 117 through the water inlet channel 118, and then be discharged to the outdoor space through the drain pipe together with the condensed water in the main water tank 117, so that the condensed water in the rear water tank 116 can be discharged to the outdoor space.

[0089] Reference Figure 5 and Figure 9 In this embodiment, a relief notch 320 is provided at a position of the thermal insulation layer 300 corresponding to the communication opening 119 .

[0090] It can be understood that an avoidance gap 320 is provided on the insulation layer 300 to ensure that the condensed water in the rear water tank 116 can smoothly flow into the main water tank 117 and be smoothly discharged to the outdoor space, so as to effectively avoid the condensed water from being retained on the rear side of the shell 100 for a long time and ensure the user experience.

[0091] Reference Figure 6 、 Figure 7 and Figure 10 In this embodiment, the auxiliary water tank 114 is higher than the horizontal height of the rear water tank 116. The auxiliary water tank 114 is located above the rear water tank 116, and a leakage port 1141 is provided at the bottom of the auxiliary water tank 114. The leakage port 1141 is used to allow the water in the auxiliary water tank 114 to flow into the rear water tank 116.

[0092] It is understood that the condensed water in the auxiliary water tank 114 can first flow into the rear water tank 116, then into the main water tank 117, and finally be discharged to the outdoor space through the drain pipe. Furthermore, by rationally arranging the communication structure between the main water tank 117, the auxiliary water tank 114, and the rear water tank 116, while ensuring that the condensed water in all water tanks in the above embodiment can be smoothly discharged to the outdoor space, the base 110 can be effectively kept small, ensuring the feasibility of embedding the embedded air conditioner indoor unit into the cabinet 400.

[0093] Reference Figure 5 and Figure 10 In this embodiment, the avoidance gap 320 is also opened corresponding to the position of the water leakage port 1141.

[0094] It can be understood that the avoidance gap 320 is opened at the position of the corresponding leakage port 1141 of the insulation layer 300, which can ensure that the condensed water in the auxiliary water tank 114 can flow smoothly into the rear water tank 116, and ensure that the condensed water in the auxiliary water tank 114 can be smoothly discharged to the outdoor space, further preventing the condensed water from falling on the floor of the indoor space, ensuring that the floor of the indoor space is dry and clean, and ensuring the user experience.

[0095] Reference Figure 4 、 Figure 6 、 Figure 7 and Figure 8 In this embodiment, the rear water receiving plate 115 includes a first water receiving plate 1151 and a second water receiving plate 1152 connected in the left and right directions, and the connection end of the first water receiving plate 1151 and the second water receiving plate 1152 is higher than the horizontal setting height of the other end of the first water receiving plate 1151 and higher than the horizontal setting height of the other end of the second water receiving plate 1152.

[0096] The number of the connecting ports 119 is set to two, and the number of the water diversion channels 118 and the avoidance gaps 320 are correspondingly set to two, and the two connecting ports 119 are respectively located at the left and right ends of the rear water tank 116, and the two avoidance gaps 320 are respectively located at the left and right ends of the insulation layer 300.

[0097] It can be understood that setting the number of water inlet channels 118 and connecting ports 119 to two can enable the condensed water in the rear water tank 116 to quickly flow into the main water tank 117 and be discharged to the outdoor space, further preventing the cabinet body 400 from becoming moldy or damaged, avoiding the appearance of moldy smell in the indoor space, and further ensuring the user experience of the embedded air-conditioning indoor unit.

[0098] Furthermore, by tilting the first water receiving plate 1151 and the second water receiving plate 1152 , the condensed water in the rear water receiving tank 116 can flow toward the connecting port 119 , ensuring smooth flow of the condensed water from the rear water receiving tank 116 to the main water receiving tank 117 .

[0099] Reference Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 、 Figure 9 and Figure 10 In this embodiment, the housing 100 further includes a peripheral frame 120 and a front cover 130. The peripheral frame 120 is disposed above, below, on the left, and on the right sides of the base 110. The front cover 130 is buckled in front of the peripheral frame 120 and the base 110 to complete the construction of the housing 100.

[0100] The following combination Figures 2 to 12 The wall-mounted air conditioner indoor unit of this embodiment will be described in detail. Figure 11 This is a structural diagram of a wall-mounted air conditioner indoor unit according to one embodiment of the present utility model; Figure 12 The figure is an exploded diagram of a wall-mounted air conditioner indoor unit according to one embodiment of the present invention.

[0101] Reference Figure 2 、 Figure 4 、 Figure 5 、 Figure 11 and Figure 12 In this embodiment, the wall-mounted air conditioner indoor unit includes a housing 100 , an indoor heat exchanger 200 and a thermal insulation layer 300 .

[0102] The indoor heat exchanger 200 is disposed in the casing 100 .

[0103] The insulation layer 300 is arranged on the rear side wall of the shell 100, and the insulation layer 300 is arranged corresponding to the indoor heat exchanger 200. The insulation layer 300 is used to limit the heat exchange between the part of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the wall-mounted air conditioner indoor unit works.

[0104] The wall-mounted air-conditioning indoor unit of this embodiment is based on the same reasons as the embedded air-conditioning indoor unit of the above embodiment. The utility model can effectively prevent the wall from being moldy or damaged, avoid the moldy smell in the indoor space, and ensure the user experience of the wall-mounted air-conditioning indoor unit.

[0105] In this embodiment, the thermal insulation layer 300 includes one or more of foam material, thermal insulation cotton, vacuum panel and metal foil.

[0106] It can be understood that the insulation layer 300 can be one or more of foam material, insulation cotton, vacuum panel and metal foil, so that the insulation layer 300 can limit the heat exchange between the part of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the indoor unit of the wall-mounted air conditioner works, so that the insulation layer can play a role in keeping cold when the wall-mounted air conditioner is running in cooling mode or dehumidification mode.

[0107] Moreover, when the thermal insulation layer 300 is a foam material, the foam material can be directly sprayed on the corresponding position to realize the construction of the thermal insulation layer 300; when the thermal insulation layer 300 is thermal insulation cotton, it can be adhered to the corresponding position through a colloid to realize the connection between the thermal insulation layer 300 and the rear side wall of the shell 100; when the thermal insulation layer 300 is a vacuum panel, it can be connected to the corresponding position through a snap fastener to realize the connection between the thermal insulation layer 300 and the rear side wall of the shell 100.

[0108] Reference Figure 2 、 Figure 3 、 Figure 4 and Figure 6 In this embodiment, the housing 100 includes a base 110. The base 110 is extended in the left-right direction, and a volute 111 extending in the left-right direction is provided on the front side of the base 110. The volute 111 is used to accommodate the indoor fan of the air conditioner indoor unit.

[0109] The base 110 includes a rear plate 112 extending left and right. The rear plate 112 is located above the volute 111 and is arranged corresponding to the indoor heat exchanger 200 . The insulation layer 300 is arranged on the rear side of the rear plate 112 .

[0110] It can be understood that since the portion of the rear side wall of the shell 100 opposite to the indoor heat exchanger 200 is the rear side wall of the rear backboard 112, the insulation layer 300 can be specifically arranged on the rear side surface of the rear backboard 112 to achieve heat exchange between the portion of the rear wall of the shell 100 corresponding to the indoor heat exchanger 200 and the air flow in the indoor space where the wall-mounted air conditioner indoor unit works.

[0111] Reference Figure 5 、 Figure 6 and Figure 7 In this embodiment, a connecting groove 113 is provided on the rear side wall of the base 110 , and a connecting protrusion 310 is provided on the side of the thermal insulation layer 300 facing the base 110 , and the connecting protrusion 310 is arranged in the connecting groove 113 .

[0112] It can be understood that by coordinating the connecting groove 113 and the connecting protrusion 310 , the contact area between the insulation layer 300 and the rear side of the base 110 can be increased, thereby ensuring the stability of the connection between the insulation layer 300 and the shell 100.

[0113] In addition, the connection protrusion 310 can be provided in the middle portion of the thermal insulation layer 300 in the up-down direction to effectively ensure the stability of the connection between the thermal insulation layer 300 and the shell 100 .

[0114] Furthermore, the number of the connecting grooves 113 and the connecting protrusions 310 can be set to be multiple accordingly to further ensure the stability of the connection between the thermal insulation layer 300 and the shell 100. The specific shapes of the connecting grooves 113 and the connecting protrusions 310 at different positions can be different.

[0115] Reference Figure 2 、 Figure 9 and Figure 10 In this embodiment, the indoor heat exchanger 200 is disposed on the base 110 , and the indoor heat exchanger 200 is located above the volute 111 .

[0116] The indoor heat exchanger 200 includes a first heat exchange section 210, which is arranged obliquely above and behind the indoor fan, and the bottom end of the first heat exchange section 210 is set toward the rear and bottom, and the rear support plate 112 is set corresponding to the bottom end of the first heat exchange section 210.

[0117] It is understandable that, because the distance between the bottom end of the first heat exchange section 210 and the rear sidewall of the housing 100 is the shortest, the portion of the rear sidewall of the housing 100 corresponding to the bottom end of the first heat exchange section 210 receives the most cooling energy. Consequently, the rear plate 112 can be positioned corresponding to the bottom end of the first heat exchange section 210, i.e., the insulation layer 300 can be positioned corresponding to the bottom end of the first heat exchange section 210, to effectively ensure the cooling performance of the insulation layer 300, effectively ensuring the insulation layer 300's ability to limit the release of condensed water from the rear side of the housing 100, and thus ensuring a better user experience.

[0118] Reference Figure 2 、 Figure 3 、 Figure 9 and Figure 10 In this embodiment, the base 110 is provided with an auxiliary water receiving tank 114 located below the first heat exchange section 210. The auxiliary water receiving tank 114 is used to receive the water flowing down from the first heat exchange section 210, and the rear support plate 112 is located above the auxiliary water receiving tank 114.

[0119] The bottom of the thermal insulation layer 300 extends to the bottom outer wall of the secondary water receiving tank 114 .

[0120] It should be understood that, in addition to the situation where the cold energy on the indoor heat exchanger 200 is directly exchanged to the rear wall of the shell 100, when the air conditioner is running in cooling mode / dehumidification mode, a large amount of condensed water will be precipitated from the indoor heat exchanger 200, and these condensed water will fall into the auxiliary water tank 114. The condensed water will bring the cold energy of the indoor heat exchanger 200 to the auxiliary water tank 114, and then cause condensed water to adhere to the outer wall of the shell 100 to form the auxiliary water tank 114.

[0121] Furthermore, extending the insulation layer 300 to the bottom outer wall of the auxiliary water tank 114 can limit heat exchange between the bottom outer wall of the auxiliary water tank 114 and the air behind the indoor unit, thereby limiting the formation of condensation on the rear outer wall of the auxiliary water tank 114. This further prevents the cabinet 400 from becoming moldy or damaged, and avoids the presence of moldy odors in the indoor space, further enhancing the user experience of the wall-mounted air conditioner indoor unit.

[0122] Reference Figure 2 、 Figure 6 、 Figure 9 and Figure 10 In this embodiment, the rear side wall of the base 110 is connected to a rear water receiving plate 115 extending toward the rear and upper part, and a rear water receiving groove 116 is formed between the rear water receiving plate 115 and the rear wall of the base 110, and the rear water receiving groove 116 is located below the rear backing plate 112, and the insulation layer 300 is arranged above the rear water receiving plate 115.

[0123] The rear water tank 116 is connected to the drain pipe of the wall-mounted air conditioner indoor unit.

[0124] It is understood that even if condensed water precipitates on the rear side wall of the housing 100, the condensed water will fall into the rear water tank 116 and then be discharged to the outdoor space through the drain pipe, thereby preventing the condensed water from being retained on the rear side of the housing 100 for a long time. Furthermore, the provision of the rear water tank 116 can further prevent the cabinet 400 from becoming moldy or damaged, and avoid the presence of a moldy odor in the indoor space, further ensuring the user experience of the wall-mounted air conditioner indoor unit.

[0125] Furthermore, since the thermal insulation layer 300 is disposed on the rear water receiving plate 115, the contact area between the housing 100 and the thermal insulation layer 300 is increased, and the rear water receiving plate 115 can bear at least part of the weight of the thermal insulation layer 300. Therefore, the aforementioned arrangement of the rear water receiving plate 115 can further ensure the stability of the connection between the thermal insulation layer 300 and the housing 100.

[0126] Reference Figure 2 、 Figure 3 、 Figure 9 and Figure 10In this embodiment, the indoor heat exchanger 200 further includes a second heat exchange section 220 and a third heat exchange section 230 . The second heat exchange section 220 is arranged obliquely above and in front of the indoor fan, and the third heat exchange section 230 is connected to the bottom of the second heat exchange section 220 .

[0127] A main water receiving tank 117 is also provided on the base 110 . The main water receiving tank 117 is located below the third heat exchange section 230 . The main water receiving tank 117 is used to receive water flowing down from the second heat exchange section 220 and the third heat exchange section 230 .

[0128] It can be understood that, by providing the main water receiving tank 117 , condensed water can be prevented from falling onto the floor of the indoor space, thereby ensuring that the floor of the indoor space is dry and clean, and ensuring the user experience.

[0129] Reference Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 In this embodiment, a water diversion channel 118 is provided on the base 110. The front end of the water diversion channel 118 is connected to the main water receiving tank 117, and the rear end of the water diversion channel 118 is connected to the rear water receiving tank 116 through the connecting port 119. The drain pipe is connected to the main water receiving tank 117, and the rear water receiving tank 116 is higher than the horizontal height of the main water receiving tank 117.

[0130] It can be understood that the condensed water in the rear water tank 116 can flow into the main water tank 117 through the water inlet channel 118, and then be discharged to the outdoor space through the drain pipe together with the condensed water in the main water tank 117, so that the condensed water in the rear water tank 116 can be discharged to the outdoor space.

[0131] Reference Figure 5 and Figure 9 In this embodiment, a relief notch 320 is provided at a position of the thermal insulation layer 300 corresponding to the communication opening 119 .

[0132] It can be understood that an avoidance gap 320 is provided on the insulation layer 300 to ensure that the condensed water in the rear water tank 116 can smoothly flow into the main water tank 117 and be smoothly discharged to the outdoor space, so as to effectively avoid the condensed water from being retained on the rear side of the shell 100 for a long time and ensure the user experience.

[0133] Reference Figure 6 、 Figure 7 and Figure 10 In this embodiment, the auxiliary water tank 114 is higher than the horizontal height of the rear water tank 116. The auxiliary water tank 114 is located above the rear water tank 116, and a leakage port 1141 is provided at the bottom of the auxiliary water tank 114. The leakage port 1141 is used to allow the water in the auxiliary water tank 114 to flow into the rear water tank 116.

[0134] It is understood that the condensed water in the auxiliary water tank 114 can first flow into the rear water tank 116, then into the main water tank 117, and finally be discharged to the outdoor space through the drain pipe. Furthermore, by rationally arranging the communication structure between the main water tank 117, the auxiliary water tank 114, and the rear water tank 116, while ensuring that the condensed water in all water tanks in the above embodiment can be smoothly discharged to the outdoor space, the base 110 can be effectively kept small, ensuring that the wall-mounted air conditioner indoor unit can have a compact size.

[0135] Reference Figure 5 and Figure 10 In this embodiment, the avoidance gap 320 is also opened corresponding to the position of the water leakage port 1141.

[0136] It can be understood that the avoidance gap 320 is opened at the position of the corresponding leakage port 1141 of the insulation layer 300, which can ensure that the condensed water in the auxiliary water tank 114 can flow smoothly into the rear water tank 116, and ensure that the condensed water in the auxiliary water tank 114 can be smoothly discharged to the outdoor space, further preventing the condensed water from falling on the floor of the indoor space, ensuring that the floor of the indoor space is dry and clean, and ensuring the user experience.

[0137] Reference Figure 4 、 Figure 6 、 Figure 7 and Figure 8 In this embodiment, the rear water receiving plate 115 includes a first water receiving plate 1151 and a second water receiving plate 1152 connected in the left and right directions, and the connection end of the first water receiving plate 1151 and the second water receiving plate 1152 is higher than the horizontal setting height of the other end of the first water receiving plate 1151 and higher than the horizontal setting height of the other end of the second water receiving plate 1152.

[0138] The number of the connecting ports 119 is set to two, and the number of the water diversion channels 118 and the avoidance gaps 320 are correspondingly set to two, and the two connecting ports 119 are respectively located at the left and right ends of the rear water tank 116, and the two avoidance gaps 320 are respectively located at the left and right ends of the insulation layer 300.

[0139] It can be understood that setting the number of water inlet channels 118 and connecting ports 119 to two can enable the condensed water in the rear water tank 116 to quickly flow into the main water tank 117 and be discharged to the outdoor space, further preventing the cabinet 400 from becoming moldy or damaged, avoiding the appearance of moldy smell in the indoor space, and further ensuring the user experience of the wall-mounted air conditioner indoor unit.

[0140] Furthermore, by tilting the first water receiving plate 1151 and the second water receiving plate 1152 , the condensed water in the rear water receiving tank 116 can flow toward the connecting port 119 , ensuring smooth flow of the condensed water from the rear water receiving tank 116 to the main water receiving tank 117 .

[0141] Reference Figure 11 and Figure 12 In this embodiment, the housing 100 further includes a connecting middle frame 140 and a front cover 130. The connecting middle frame 140 is disposed above, below, on the left, on the right, and in front of the base 110. The front cover 130 is buckled in front of the connecting middle frame 140 and the base 110 to complete the construction of the housing 100.
