[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] like Figures 1 to 6 As shown, Embodiment 1 of the present invention provides a cleaning device for installation within the indoor unit housing 60 of an air conditioner indoor unit. The cleaning device includes a cleaning structure comprising a nozzle 10, a first drive assembly 20, a rotary joint 30, and a second drive assembly 40. The first drive assembly 20 is drivenly connected to the nozzle 10 to drive the nozzle 10 to rotate along a first preset rotation direction. The nozzle 10 is rotatably mounted on the rotary joint 30 along the first preset rotation direction. The second drive assembly 40 is drivenly connected to the rotary joint 30 to drive the nozzle 10 to rotate along a second preset rotation direction via the rotary joint 30. The second preset rotation direction is set at a predetermined angle to the first preset rotation direction.

[0031] Specifically, in this embodiment, the first drive assembly 20 drives the nozzle 10 to rotate up and down, and the second drive assembly 40 drives the nozzle 10 to rotate along its axis (i.e., to rotate within a plane). The nozzle 10 in this embodiment can rotate both within a plane and up and down, thereby increasing the cleaning range of the nozzle 10, facilitating comprehensive cleaning of the components inside the indoor unit housing 60. Therefore, the cleaning device provided in this embodiment can solve the technical problem of the limited cleaning range of existing air conditioner indoor unit cleaning devices.

[0032] Specifically, the cleaning structure in this embodiment also includes a bracket 50, which has mounting holes, and the nozzle 10 is disposed in the mounting holes. The first drive assembly 20 is drivenly connected to the bracket 50 so that the first drive assembly 20 drives the nozzle 10 to rotate through the bracket 50. This arrangement facilitates the installation of the nozzle 10 and allows for more stable rotation of the nozzle 10 through the bracket 50.

[0033] In this embodiment, the first drive assembly 20 includes a first support 21, which is rotatably disposed along a first preset rotation direction. A guide structure is provided on the first support 21, and at least a portion of the bracket 50 is movably disposed on the guide structure to guide the bracket 50 to rotate along a second preset rotation direction. This arrangement avoids interference between the movements in the first and second preset rotation directions, allowing the nozzle 10 to smoothly achieve vertical and axial rotation, thereby further expanding the cleaning range.

[0034] Specifically, in this embodiment, the guide structure is an annular protrusion 211, and the bracket 50 is provided with an annular groove 53. The annular groove 53 is rotatably provided on the annular protrusion 211 so that the nozzle 10 can rotate smoothly along the second preset rotation direction (i.e., axial rotation).

[0035] In this embodiment, the bracket 50 includes a first body portion 51 and a first connecting portion 52. The first connecting portion 52 is disposed on the first body portion 51 and rotatably disposed on the rotary joint 30, so that the first body portion 51 can rotate relative to the rotary joint 30 along a first preset rotation direction (the first preset rotation direction is the up-down rotation direction) via the first connecting portion 52. This arrangement facilitates smooth rotation of the bracket 50 relative to the rotary joint 30 along the first preset rotation direction, ensuring smooth movement.

[0036] Specifically, in this embodiment, the first connecting part 52 includes a first connecting block 521 and a second connecting block 522, which are disposed opposite to each other. The first connecting block 521 is provided with a first connecting hole 523, and the second connecting block 522 is provided with a second connecting hole 524. The rotary joint 30 is provided with a first connecting protrusion 31 and a second connecting protrusion, which are disposed opposite to each other. The first connecting hole 523 is rotatably disposed on the first connecting protrusion 31, and the second connecting hole 524 is rotatably disposed on the second connecting protrusion. This arrangement can further improve the smoothness of the rotation of the bracket 50, so as to ensure the cleaning range of the nozzle 10.

[0037] In this embodiment, the second drive assembly 40 includes a second support 41, which rotates along a second preset rotation direction. The second support 41 includes a second body portion 411 and a second connecting portion 412. The second body portion 411 has a first annular structure, and the second connecting portion 412 is disposed on the second body portion 411 so that the second body portion 411 is fixedly connected to the rotary joint 30 through the second connecting portion 412. With this arrangement, the second support 41 can stably drive the nozzle 10 to rotate along the second preset rotation direction through the rotary joint 30, thereby ensuring smooth rotation.

[0038] Specifically, in this embodiment, the second connecting part 412 includes a third connecting block 4121 and a fourth connecting block 4122, which are arranged opposite to each other. The third connecting block 4121 is provided with a third connecting hole 4123, and the fourth connecting block 4122 is provided with a fourth connecting hole 4124. The rotary joint 30 is provided with a third connecting protrusion 32 and a fourth connecting protrusion, which are arranged opposite to each other. The third connecting hole 4123 is provided on the third connecting protrusion 32, and the fourth connecting hole 4124 is provided on the fourth connecting protrusion, so that the second body part 411 is fixedly connected to the rotary joint 30 through the second connecting part 412, thereby improving the stability of the connection and facilitating the smooth rotation of the nozzle 10 along the second preset rotation direction.

[0039] In this embodiment, the first driving assembly 20 further includes a driving rod 22, and a first support 21 is disposed at the end of the driving rod 22. The driving rod 22 rotates along a first preset rotation direction so as to drive the first support 21 to rotate so as to smoothly drive the nozzle 10 to rotate.

[0040] Specifically, in this embodiment, the first support 21 includes a third body portion 212 and a third connecting portion 213. The third body portion 212 has a second annular structure, and the third connecting portion 213 is disposed on the third body portion 212. The third connecting portion 213 is provided with a fifth connecting hole 2131. The end of the drive rod 22 is inserted into the fifth connecting hole 2131 to fix the drive rod 22 to the first support 21, so as to drive the third body portion 212 to rotate. In this example, there are two third connecting portions 213, which are arranged opposite to each other. The fifth connecting holes 2131 on both third connecting portions 213 are used to connect with the drive rod 22.

[0041] In this embodiment, there are multiple cleaning structures connected together along the extension direction of the drive rod 22. This arrangement facilitates a larger cleaning range, thereby improving the cleaning effect.

[0042] Specifically, to facilitate control of the movement of the nozzle 10, the cleaning device in this embodiment further includes a controller, a first motor, and a second motor. Both the first and second motors are connected to the controller to control their operation. The first motor is connected to the first drive assembly 20 to drive the first drive assembly 20 to rotate in a first preset rotation direction. The second motor is connected to the second drive assembly 40 to drive the second drive assembly 40 to rotate in a second preset rotation direction.

[0043] During cleaning, the first motor drives the nozzle 10 to rotate up and down via the first drive assembly 20, and the second motor drives the nozzle 10 to rotate around its axis via the second drive assembly 40. This allows water to be sprayed both in the plane and in the vertical direction. When multiple nozzles 10 are connected, their rotation in the plane can be controlled individually, facilitating the cleaning of the entire cross-flow fan 70 and the air duct, expanding the cleaning area, and achieving a comprehensive cleaning effect. Specifically, in this embodiment, the nozzle 11 of the nozzle 10 can be L-shaped, which reduces the water outlet area of ​​the nozzle 11, thereby reducing the water output, saving water, and increasing the water pressure for a more thorough cleaning. The design can be tailored to the required cleaning range.

[0044] like Figure 7 As shown, Embodiment 2 of the present invention provides an air conditioner indoor unit, which includes an indoor unit housing 60 and a cleaning device. The cleaning device is disposed inside the indoor unit housing 60 and is the cleaning device provided in Embodiment 1.

[0045] Specifically, the indoor unit of the air conditioner in this embodiment also includes a cross-flow fan blade 70, which is disposed inside the indoor unit housing 60, and the nozzle 10 of the cleaning device is positioned towards the cross-flow fan blade 70. Specifically, the cleaning device can be mounted on the bottom housing 110. This arrangement facilitates better cleaning of the cross-flow fan blade 70. The indoor unit of the air conditioner in this embodiment also includes an evaporator 80 and a cross-flow fan blade 70, both of which are disposed inside the indoor unit housing 60. When the indoor unit is in operation, indoor air is drawn in through the air inlet 90, undergoes heat exchange through the evaporator 80, and is then blown out through the air outlet along the air guide plate 100 to achieve cooling and heating of the indoor environment.

[0046] As can be seen from the above description, the above embodiments of the present invention achieve the following technical effects: expanding the cleaning range of internal components of the air conditioner indoor unit and improving the cleaning effect.
