[0050] Combine the following Figures 1 to 4 The wall-mounted air conditioner indoor unit of this embodiment will be described in detail. Figure 1 is one of the cross-sectional schematic diagrams of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention; Figure 2 is a second cross-sectional schematic diagram of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention, and Figure 2 exist Figure 1 The air duct barrel is hidden on the basis of the Figure 3 is a schematic structural diagram of an indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention; Figure 4 It is a schematic diagram of the structure of the air duct barrel in the indoor unit of a wall-mounted air conditioner according to an embodiment of the present invention.

[0051] Reference Figure 1 , Figure 2 and Figure 3In this embodiment, the indoor unit of the wall-mounted air conditioner includes a housing 100, a volute 200, an air duct barrel 300, an air inlet cover 410 and an air outlet plate 420.

The air inlet cover 410 is arranged at the air vent 320, and the air inlet cover 410 is used to open or close the air vent 320; the air outlet plate 420 is arranged at the air outlet 330, and the air outlet plate 420 is used to open or close the air outlet 330; the air duct barrel 300 has an air outlet state in which the air vent 320 is arranged relative to the air supply port 210 and the air outlet 330 is arranged relative to the avoidance port 110 when the air vent 320 and the air outlet 330 are opened; the air duct barrel 300 also has an air duct cleaning state in which the rotation is maintained when the air vent 320 and the air outlet 330 are closed.

[0052] Since the wall-mounted air conditioner indoor unit of this embodiment has an air duct barrel 300, an air inlet cover 410 and an air outlet plate 420, the air duct barrel 300 is rotatable in the housing 100, the air duct barrel 300 is arranged along the length direction of the volute 200, the air duct barrel 300 is located below the volute 200, and the rotation center axis of the air duct barrel 300 is arranged along the length direction of the volute 200, and an air duct cavity 310 for holding water is arranged in the air duct barrel 300, and a vent 320 and an air outlet 330 connected to the air duct cavity 310 are arranged on the outer peripheral side of the air duct barrel 300; the air inlet cover 410 is arranged at the vent 320, and the air inlet cover 410 is used to open or close the vent 320; the air outlet plate 420 is arranged at the air outlet 33 0, the air outlet plate 420 is used to open or close the air outlet 330; and the air duct barrel 300 has an air outlet state in which the air duct 320 is arranged relative to the air supply port 210 and the air outlet 330 is arranged relative to the avoidance port 110 when the air duct 320 and the air outlet 330 are opened, so as to realize the normal air supply mode and ensure the normal operation of the indoor unit of the wall-mounted air conditioner; the air duct barrel 300 also has an air duct cleaning state in which the air duct is kept rotating when the air duct 320 and the air outlet 330 are closed, so that the air duct barrel 300 can use the water in the air duct cavity 310 to clean the inner wall of the air duct cavity 310, the air outlet 330, and the inner side of the air inlet cover 410 and the air outlet plate 420 facing the air duct cavity 310. Therefore, this embodiment enables the indoor unit of the wall-mounted air conditioner to realize the self-cleaning function of the air outlet 330, the air guide plate, the air duct cavity 310 and other parts.

[0053] Reference Figure 3 In this embodiment, the left and right ends of the air duct barrel 300 are rotatably connected to the shell 100.

[0054] In a modified embodiment, the left and right ends of the air duct barrel 300 are rotatably connected to a base disposed in the shell 100 of the indoor unit of the wall-mounted air conditioner.

[0055] Reference Figure 4 In this embodiment, the indoor unit of the wall-mounted air conditioner further includes a cleaning drive device 500. The cleaning drive device 500 is drivingly connected to the air duct barrel 300, and the cleaning drive device 500 is connected to the housing 100, and the cleaning drive device 500 is used to drive the air duct barrel 300 to rotate. In this way, the rotation of the air duct barrel 300 can be maintained, and the air duct barrel 300 can be switched between the air duct cleaning state and the air outlet state.

[0056] Specifically, the cleaning drive device 500 may include a driving motor, and the motor shaft of the driving motor is directly connected to the geometric center point of the left end face / right end face of the air duct barrel 300; and the cleaning drive device 500 may also include a driving motor and a power transmission component (such as a gear set), and the motor shaft of the driving motor is driven and connected to the left end face / right end face of the air duct barrel 300 through the power transmission component.

[0057] In addition, the number of cleaning drive devices 500 can be set to one, which is driven and connected to the left end face / right end face of the air duct barrel 300, or can be set to two, which are driven and connected to the left and right ends of the air duct barrel 300.

[0058] Reference Figure 4 In this embodiment, the indoor unit of the wall-mounted air conditioner further includes a telescopic mechanism 600. The telescopic mechanism 600 is connected between the left end of the air duct barrel 300 and the housing 100 and between the right end of the air duct barrel 300 and the housing 100. The telescopic mechanism 600 is used to drive the air duct barrel 300 to extend or retract into the housing 100 through the avoidance opening 110; the cleaning drive device 500 is disposed on the telescopic mechanism 600.

[0059] Specifically, the telescopic mechanism 600 can be an electric telescopic rod, or a pneumatic cylinder, a hydraulic cylinder, etc., all of which can drive the air duct barrel 300 to extend or retract the shell 100.

[0060] It can be understood that, by setting up the telescopic mechanism 600, the air duct barrel 300 can be extended out of the shell 100 through the avoidance opening 110, and then, maintenance personnel can easily disassemble, repair and maintain the air duct barrel 300 extending out of the shell 100.

[0061] Reference Figure 1In this embodiment, the end of the air inlet cover 410 that limits its length can be rotatably connected to the end of the vent 320 that limits its length to open or close the vent 320; and the air inlet cover 410 rotates around its rotation center axis into the air duct cavity 310 to open the vent 320.

[0062] It should be noted that if the end of the air inlet cover 410 that limits the width can be rotatably connected to the end of the air vent 320 that limits the width, if the radial dimension of the air duct barrel 300 is not large enough, the air inlet cover 410 may abut against the inner wall of the air duct cavity 310 when opening the air duct 320 and cannot fully open the air duct 320. Therefore, the end of the air inlet cover 410 that limits its length can be rotatably connected to the end of the air vent 320 that limits its length. Such a setting allows the air inlet cover 410 to fully open the air vent 320, ensuring the air supply volume of the air conditioner when the air duct barrel 300 is in the air outlet state.

[0063] Furthermore, by rotating the air inlet cover 410 around its rotation center axis into the air duct cavity 310 to open the vent 320, the rotation of the fan 220 will not be disturbed, thereby ensuring the normal operation of the indoor unit of the wall-mounted air conditioner.

[0064] In addition, the rotation of the air inlet cover 410 can also be achieved by setting an air inlet drive motor, for example, by setting the air inlet drive motor on the air duct barrel 300, and drivingly connecting the motor shaft of the air inlet drive motor to the rotation center axis of the air inlet cover 410.

[0065] In a modified embodiment, an air inlet expansion slot is opened in the wall of the air duct barrel 300, and the slot of the air inlet expansion slot is arranged at the end of the vent 320 that limits its length. The air inlet cover 410 is telescopically slidably arranged in the air inlet expansion slot, so that the vent 320 can be opened or closed. Similarly, the air supply volume of the air conditioner can be ensured when the air duct barrel 300 is in the air outlet state, and the rotation of the fan 220 will not be interfered with, thereby ensuring the normal operation of the indoor unit of the wall-mounted air conditioner.

[0066] Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, the end of the air outlet plate 420 that defines its length can be rotatably connected to the end of the air outlet 330 that defines its length to open or close the air outlet 330.

[0067] It can be known that, by configuring the end of the air outlet plate 420 that limits its length to be rotatably connected to the end of the air outlet 330 that limits its length, if the air outlet plate 420 rotates around its rotation center axis toward the inside of the air duct cavity 310, the air outlet plate 420 can fully open the air outlet 330; if the air outlet plate 420 rotates around its rotation center axis toward the outside of the air duct cavity 310, most of the structure of the air outlet plate 420 will not be located in the indoor space and affect the normal activities of the user.

[0068] In addition, the rotation of the air outlet plate 420 can also be achieved by setting an air outlet drive motor, for example, by setting the air outlet drive motor on the air duct barrel 300, and drivingly connecting the motor shaft of the air outlet drive motor to the rotation center axis of the air outlet plate 420.

[0069] In a modified embodiment, an air outlet expansion slot is opened in the wall of the air duct barrel 300, and the slot of the air outlet expansion slot is arranged at the end of the air outlet 330 that limits its length. The air outlet plate 420 is telescopically slidably arranged in the air outlet expansion slot, so that the air outlet 320 can be opened or closed. Similarly, the air supply volume of the air conditioner can be ensured when the air duct barrel 300 is in the air outlet state without interfering with the normal activities of the user.

[0070] Reference Figure 1 , Figure 3 and Figure 4 In this embodiment, the air outlet plate 420 rotates around its rotation center axis toward the outside of the air duct barrel 300 to open the air outlet 330, and the air outlet plate 420 is also used to guide the airflow flowing out of the air outlet 330 in the vertical direction.

[0071] It can be understood that when the air outlet plate 420 rotates around its rotation center axis toward the outside of the air duct barrel 300 to open the air outlet 330, the direction and air supply mode of the air flow out of the air outlet 330 can also be guided by the rotation of the air outlet plate 420, for example, front and lower air outlet, front air outlet to prevent direct blowing, and upper and lower sweeping air modes, so as to ensure the normal operation of the indoor unit of the wall-mounted air conditioner.

[0072] In this embodiment, sealing rings are provided on the vents 320 and the air outlets 330, and / or at the edges of the air inlet cover 410 and the air outlet plate 420 to ensure the sealing of the air duct cavity 310 in the air duct barrel 300 when the air inlet cover 410 closes the vents 320, to ensure that water in the air duct cavity 310 does not leak out, thereby ensuring the user experience.

[0073] In this embodiment, the avoidance opening 110 is extended along the length direction of the housing 100 to reduce the loss of airflow entering the air duct cavity 310, so as to ensure the air output of the indoor unit of the wall-mounted air conditioner.

[0074] In this embodiment, the air supply port 210 is extended along the length direction of the volute 200 to reduce the loss of air flow entering the air duct cavity 310 and ensure the air output of the indoor unit of the wall-mounted air conditioner.

[0075] Reference Figure 3 and Figure 4 In this embodiment, the vent 320 and the air outlet 330 are extended along the axial direction of the air duct barrel 300 to ensure the air outlet area of ​​the indoor unit of the wall-mounted air conditioner.

[0076] Reference Figure 3 and Figure 4 In this embodiment, the rotation center axis of the air duct barrel 300 passes through the geometric center points of its left and right end surfaces to ensure the rotation stability of the air duct barrel 300 when it is in the air duct cleaning state and when switching between the air outlet state and the air duct cleaning state.

[0077] Reference Figure 1 In the present embodiment, the outer contour of the cross section of the air duct barrel 300 is circular to ensure the size of the air duct barrel 300 and its stability during rotation.

[0078] Reference Figure 1 and Figure 2 In this embodiment, the indoor unit of the wall-mounted air conditioner further includes an indoor heat exchanger 710, a water receiving tray 720 and a water pipe. The indoor heat exchanger 710 is arranged in the housing 100; the water receiving tray 720 is located at the bottom end of the indoor heat exchanger 710, and the water receiving tray 720 is arranged on the volute 200; the first end of the water pipe is connected to the water outlet of the water receiving tray 720, and the second end of the water pipe passes through the left end or the right end of the air duct barrel 300 and is connected to the air duct cavity 310, and the central axis of the second end of the water pipe is collinear with the rotation central axis of the air duct barrel 300; the water outlet is provided with a first electric on-off water valve.

[0079] It can be understood that the water receiving pan 720 is used to temporarily store the condensed water generated by the indoor heat exchanger 710 during operation. When the interior of the air duct barrel 300 needs to be cleaned, the first electric on-off water valve can be opened to discharge the water in the water receiving pan 720 into the air duct barrel 300, and the indoor unit of the wall-mounted air conditioner can complete the cleaning process. When the interior of the air duct barrel 300 does not need to be cleaned, the first electric on-off water valve can be closed to temporarily store the condensed water in the water receiving pan 720, and the condensed water in the water receiving pan 720 can be discharged after reaching a certain amount. In addition, the indoor unit of the wall-mounted air conditioner of this embodiment uses condensed water to clean the air duct cavity 310, avoiding the waste of water resources and ensuring energy saving.

[0080] In addition, the central axis of the second end of the water pipe and the rotational central axis of the air duct barrel 300 are made colinear to ensure the normal operation of the above-mentioned water delivery process and self-cleaning function, and the water pipe and the air duct barrel 300 can be contacted and connected through a bearing structure.

[0081] Reference Figure 1 and Figure 2 In the present embodiment, the indoor unit of the wall-mounted air conditioner further comprises a fan 220 arranged in the volute 200, and an air inlet 120 is arranged on the shell 100, so that when the indoor unit of the wall-mounted air conditioner is in the process of cooling, heating or air supply, and the air duct barrel 300 is in the air outlet state, the fan 220 can introduce the airflow in the indoor space acted by the indoor unit of the wall-mounted air conditioner into the interior of the shell 100 through the air inlet 120, and promote the airflow to pass through the indoor heat exchanger 710 and then enter the indoor space through the air supply port 210, the vent 320, the air outlet 330 (and the avoidance port 110) in sequence after heat exchange with the indoor heat exchanger 710.

[0082] Reference Figure 1 In the present embodiment, a drain outlet 340 is also provided on the air duct barrel 300 , and a second electric opening and closing water valve is provided on the drain outlet 340 ; and the drain outlet 340 is provided on the peripheral side of the air duct barrel 300 .

[0083] Specifically, the drain port 340 can be set at the bottom of the air duct barrel 300 when the ventilation port 320 is set relative to the air supply port 210 and the air outlet 330 is set relative to the avoidance port 110 to ensure that the water in the air duct barrel 300 can be completely discharged.

[0084] Reference Figure 1 In this embodiment, a drain outlet 340 is also provided on the air duct barrel 300, and a second electric opening and closing water valve is provided on the drain outlet 340. The drain outlet 340 is arranged at the left end or the right end of the air duct barrel 300, and the drain outlet 340 is arranged away from the rotation center axis of the air duct barrel 300.

[0085] Specifically, the drain port 340 can be set at the bottom of the air duct barrel 300 when the ventilation port 320 is set relative to the air supply port 210 and the air outlet 330 is set relative to the avoidance port 110 to ensure that the water in the air duct barrel 300 can be completely discharged.

[0086] In addition, regarding the positions where the two types of drain outlets 340 are arranged, after the wall-mounted air conditioner indoor unit of this embodiment has finished cleaning the inner wall of the air duct cavity 310, the air outlet 330, the air inlet cover 410 and the air outlet plate 420, the user can connect a drain pipe to the drain outlet 340 and open the second electric on-off water valve to realize the drainage process in the air duct cavity 310.
