[0043] Figure 1 is a schematic structural diagram of the interior of the housing of a wall-mounted air conditioner indoor unit according to an embodiment of the present utility model, as Figure 1 shown, and with reference to Figures 2 to 4 , an embodiment of the present utility model provides a wall-mounted air conditioner indoor unit, including a housing 100, a heat exchanger 200, and a refrigerant connection pipe 300.

[0044] An installation opening 110 is provided on the front side wall of the housing 100, and an operation chamber 120 is arranged at the rear side of the installation opening 110.

[0045] The heat exchanger 200 is located inside the housing 100.

[0046] The refrigerant connecting pipe 300 is located inside the housing 100. One end of the refrigerant connecting pipe 300 is connected to the heat exchanger 200, and the other end forms a first joint 301 for connecting to the connecting pipe 400 of the outdoor unit. The first joint 301 is located inside the operation chamber 120.

[0047] In this embodiment, the wall-mounted air conditioner indoor unit includes a heat exchanger 200. A refrigerant connecting pipe 300 is connected to the heat exchanger 200, and the refrigerant connecting pipe 300 is connected to the air conditioner outdoor unit through the connecting pipe 400. The first joint 301 of the refrigerant connecting pipe 300 is located inside the operation chamber 120. After the wall-mounted air conditioner indoor unit is installed on the indoor wall, the user or maintenance personnel can connect the connecting pipe 400 to the first joint 301 through the installation opening 110 with the opening facing forward, or perform maintenance on the first joint 301.

[0048] Compared with the wall-mounted air conditioner indoor unit with the first joint 301 arranged at the rear side of the air conditioner, when connecting the refrigerant connecting pipe 300 and the connecting pipe 400 in the present invention, it is not necessary to first connect the refrigerant connecting pipe 300 and the connecting pipe 400 and then install the indoor unit on the indoor wall, and when maintenance is required at the first joint 301, it is not necessary to first remove the wall-mounted air conditioner indoor unit from the wall and then connect the refrigerant connecting pipe 300 and the connecting pipe 400, which reduces the installation or maintenance difficulty and thus improves the installation or maintenance efficiency.

[0049] In some embodiments of the present invention, as Figure 1 shown, the heat exchanger 200 extends along the length direction of the housing 100.

[0050] The first joint 301 is located on one side in the length direction of the heat exchanger 200.

[0051] In this embodiment, air enters from the air inlet 510 of the wall-mounted air conditioner indoor unit, exchanges heat through the heat exchanger 200, and is then blown out through the air outlet of the wall-mounted air conditioner indoor unit. Since the first joint 301 is arranged on one side in the length direction of the heat exchanger 200, interference of the first joint 301 on the air inlet and outlet of the wall-mounted air conditioner indoor unit is avoided, and the heat exchange efficiency of the wall-mounted air conditioner indoor unit is not affected.

[0052] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the housing 100 extends horizontally.

[0053] The first joint 301 of the refrigerant connecting pipe 300 is higher than the top of the heat exchanger 200.

[0054] In this embodiment, the first joint 301 is located above one side in the length direction of the heat exchanger 200, such that there is a relatively large interval between the heat exchanger 200 and the first joint 301. When a user or a maintenance personnel installs the connecting pipe 400 on the first joint 301, or performs maintenance on the first joint 301, the interference is relatively small, reducing the difficulty of installing the connecting pipe 400 on the first joint 301 or performing maintenance on the first joint 301, and also reducing the situation of knocking against the heat exchanger 200 or even causing damage to the heat exchanger 200.

[0055] In some embodiments of the present utility model, as Figure 3 and Figure 4 shown, the first joint 301 is arranged backward.

[0056] In this embodiment, the first joint 301 is cylindrical, the axis of the first joint 301 extends in the front-rear direction, and the first joint 301 is arranged backward, so that the connecting pipe 400 is connected to the first joint 301 from the rear side of the first joint 301, such that the connecting pipe 400 is arranged close to the wall, facilitating the connection between the refrigerant connecting pipe 300 and the air conditioner outdoor unit outside the wall.

[0057] Moreover, the first joint 301 is arranged backward, reducing the bending of the connecting pipe 400, avoiding the reduction in the production efficiency of the connecting pipe 400, and also avoiding the situation where the connecting pipe 400 is easily damaged or the conveying efficiency of the connecting pipe 400 is reduced due to excessive bending of the connecting pipe 400, improving the quality of the air conditioner indoor unit.

[0058] In some embodiments of the present utility model, as Figure 4 shown, the refrigerant connecting pipe 300 includes a first conveying section 310, a second conveying section 320, and a third conveying section 330.

[0059] The first conveying section 310 extends in the front-rear direction, and the first joint 301 is arranged on the first conveying section 310.

[0060] The second conveying section 320 extends in the up-down direction and is connected to the front end of the first conveying section 310.

[0061] One end of the third conveying section 330 is connected to the bottom end of the second conveying section 320, and the other end is connected to the heat exchanger 200.

[0062] In this embodiment, the third conveying section 330 is connected to the heat exchanger 200, and the second conveying section 320 extends upward, such that the first conveying section 310 is located above the heat exchanger 200, and further such that the first joint 301 is located above the heat exchanger 200.

[0063] The first conveying section 310 extends in the front-rear direction, and the first joint 301 is arranged backward. The connecting pipe 400 is connected to the first joint 301 from the rear side of the first joint 301, so that the connecting pipe 400 is arranged close to the wall, facilitating the connection between the refrigerant connecting pipe 300 and the air conditioner outdoor unit outside the wall. Moreover, the bending of the connecting pipe 400 is reduced, avoiding the reduction of the production efficiency of the connecting pipe 400, and also avoiding the situation that the connecting pipe 400 is easily damaged due to excessive bending of the connecting pipe 400 or the reduction of the conveying efficiency of the connecting pipe 400, improving the quality of the air conditioner indoor unit.

[0064] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, a detachable cover plate 500 is provided at the installation opening 110.

[0065] In this embodiment, the cover plate 500 plays a role in shielding the components inside the housing 100, avoiding the exposure of the components inside the housing 100 and affecting the overall aesthetics of the wall-mounted air conditioner indoor unit, and also avoiding the components inside the housing 100 of the wall-mounted air conditioner indoor unit from being knocked, improving the user experience.

[0066] A detachable cover plate 500 is provided at the installation opening 110.

[0067] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the cover plate 500 is configured to shield the installation opening 110.

[0068] In this embodiment, the setting of the cover plate 500 avoids dust and sundries from entering the inside of the installation opening 110, reducing the cleaning and maintenance of the wall-mounted air conditioner indoor unit.

[0069] In some embodiments of the present invention, as Figure 2 shown, the cover plate 500 is the front panel of the housing 100, and an air inlet 510 is provided on the front panel.

[0070] In this embodiment, the air inlet 510 is provided on the front panel of the housing 100, so that there is no need to reserve an air inlet passage with an interval from the air inlet 510 above the wall-mounted air conditioner indoor unit, enabling the user to make full use of the space above the wall-mounted air conditioner indoor unit.

[0071] Furthermore, the wall-mounted air conditioner indoor unit can be installed inside the cabinet. When the wall-mounted air conditioner indoor unit is installed inside the cabinet, when the wall-mounted air conditioner indoor unit is not needed, the cabinet door can be closed, thereby reducing the accumulation of dust, keeping the wall-mounted air conditioner indoor unit clean, and improving the user experience.

[0072] In some embodiments of the present invention, as Figure 1and Figure 2 As shown in Figure 2 , the first joint 301 is located on the upper side of the air inlet 510.

[0073] In this embodiment, the first joint 301 is located on the upper side of the air inlet 510, which avoids the exposure of the first joint 301 from the air inlet 510, and further avoids the situation that the first joint 301 is knocked or even damaged from the air inlet 510.

[0074] Moreover, setting the first joint 301 on the upper side of the air inlet 510 can also avoid affecting the entry of air from the air inlet 510, ensure that the air intake volume of the wall-mounted air conditioner indoor unit is not affected by the first joint 301, and thus improve the heat exchange efficiency of the air conditioner.

[0075] The embodiment of the present utility model also provides an air conditioner, including the wall-mounted air conditioner indoor unit, the air conditioner outdoor unit and the connecting pipe 400 in any of the above embodiments.

[0076] One end of the connecting pipe 400 is connected to the air conditioner outdoor unit, and the other end is connected to the first joint 301.

[0077] In this embodiment, the first joint 301 is located in the operation chamber 120. After the wall-mounted air conditioner indoor unit is installed on the indoor wall, the user or the maintenance personnel can install the connecting pipe 400 on the first joint 301 through the installation opening 110 with the opening facing forward, so that the air conditioner indoor unit is connected to the air conditioner outdoor unit. Or the user or the maintenance personnel can perform maintenance on the first joint 301 through the installation opening 110 with the opening facing forward.

[0078] Compared with the air conditioner in which the indoor unit with the first joint 301 located at the rear side of the air conditioner is a wall-mounted air conditioner indoor unit, in the present utility model, when connecting the refrigerant connecting pipe 300 and the connecting pipe 400, it is not necessary to first connect the refrigerant connecting pipe 300 and the connecting pipe 400 and then install the indoor unit on the indoor wall, and when it is necessary to perform maintenance on the first joint 301, it is not necessary to first remove the wall-mounted air conditioner indoor unit from the wall and then connect the refrigerant connecting pipe 300 and the connecting pipe 400, which reduces the installation or maintenance difficulty and thus improves the installation or maintenance efficiency.

[0079] In some embodiments of the air conditioner of the present utility model, as Figure 4 shown, the connecting pipe 400 includes a first connecting section 410 connected to the first joint 301 and a second connecting section 420 connected to the rear end of the first connecting section 410. The first connecting section 410 extends in the front-rear direction, and the second connecting section 420 extends in the up-down direction.

[0080] Further, the connecting pipe 400 further includes a third connecting section, one end of which is connected to the bottom of the second connecting section 420, and the other end is connected to the air conditioner outdoor unit.

[0081] In this embodiment, the first connecting section 410 is coaxially arranged with the first conveying section 310. The first connecting section 410 extends in the front-rear direction and is connected to the first joint 301 to enable the heat exchanger 200 to communicate with the connecting pipe 400.

[0082] The second connecting section 420 is connected to the rear side of the first connecting section 410, so that the second connecting section 420 is arranged closer to the indoor wall, facilitating the connecting pipe 400 to pass through the wall to connect the wall-mounted air conditioner indoor unit and the air conditioner outdoor unit.

[0083] Arranging the connecting pipe 400 on the side of the housing 100 close to the indoor wall can also prevent the connecting pipe 400 from being exposed and knocked, improve the quality of the wall-mounted air conditioner indoor unit, and further improve the service life of the wall-mounted air conditioner indoor unit.

[0084] Moreover, the second conveying section 320 and the second connecting section 420 are arranged at intervals in the front-rear direction, leaving space for the arrangement of the third conveying section 330 between the second conveying section 320 and the second connecting section 420, making the arrangement of the refrigerant connecting pipe 300 and the connecting pipe 400 more compact, improving the space utilization rate inside the housing 100, and increasing the available scenarios of the air conditioner.

[0085] The internal structure of the wall-mounted air conditioner indoor unit is arranged compactly, reducing the overall volume of the wall-mounted air conditioner indoor unit. When the wall-mounted air conditioner indoor unit is installed inside the cabinet, the volume occupied by the cabinet is reduced, improving the user experience. Among them, the cabinet can be a wardrobe, a cabinet or a display cabinet, etc.

[0086] At this point, those skilled in the art should recognize that although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived from the content disclosed in the present invention without departing from the spirit and scope of the present invention.
