[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] like Figures 1 to 4 As shown, embodiment 1 of the present invention provides an air-conditioning indoor unit, which includes an indoor unit housing 10, a pump body 20, a cleaning structure and a sound insulation component. The pump body 20 and the cleaning structure are both arranged in the indoor unit housing 10, and the pump body 20 is connected to the cleaning structure to provide a cleaning water source to the cleaning structure through the pump body 20.

[0025] Specifically, the air conditioner indoor unit in this embodiment also includes a filter assembly 50 and a water tank 60. The filter assembly 50 is arranged in the indoor unit housing 10. The cleaning head of the cleaning structure is arranged toward the filter assembly 50 to effectively clean the filter assembly 50 through the cleaning structure, so as to ensure the cleanliness of the filter assembly 50.

[0026] In this embodiment, the pump body 20 and the water tank 60 are both arranged at the end of the filter assembly 50, that is, the pump body 20 and the water tank 60 are both arranged at the end of the indoor unit housing 10. With such a structural layout, the compactness of the internal structure of the air-conditioning indoor unit can be improved, the internal structure can be optimized, and the volume occupied by the air-conditioning indoor unit can be reduced. Therefore, the air-conditioning indoor unit provided by this embodiment can solve the technical problem of the large volume of the air-conditioning indoor unit with a cleaning function in the prior art.

[0027] Preferably, the water tank 60 in this embodiment is arranged around the periphery of the pump body 20. Such a structural arrangement can further improve the internal structure to improve the compactness of the arrangement, further optimize the layout of the internal structure, better increase the volume of the water tank 60, and reduce the volume of the air conditioner indoor unit.

[0028] Specifically, the pump head of the pump body 20 in this embodiment can be arranged toward the bottom of the indoor unit housing 10, that is, the pump head of the pump body 20 can be placed in the gap between the components at the bottom of the indoor unit. Alternatively, the pump head of the pump body 20 is arranged toward the top of the indoor unit housing 10, so that the pump head of the pump body 20 will occupy a certain space, which is not conducive to fully utilizing the internal space of the indoor unit housing 10.

[0029] Preferably, the pump head of the pump body 20 in this embodiment is arranged toward the bottom of the indoor unit housing 10, so that there is a sufficient gap between the pump body 20 and the air inlet panel 12, and the first box body 61 is located between the pump body 20 and the air inlet panel 12, so as to make full use of the internal space of the indoor unit housing 10, improve the compactness of the structure, and optimize the spatial layout. By reasonably arranging the pump body 20, the size of the whole machine can be reduced, the volume of the water tank 60 can be increased, and the noise of the pump body 20 can be reduced.

[0030] Specifically, the indoor unit housing 10 in this embodiment includes a mounting panel 11, and the mounting panel 11 is used to be mounted on the mounting base. The distance between the center line of the pump body 20 (the pump body 20 is a symmetrical structure, and the pump body 20 is symmetrical relative to the center line) and the mounting panel 11 is L1, and the thickness of the indoor unit housing 10 is L, 1 / 6<L1 / L<3 / 4. With such a structural setting, the structural layout can be optimized and the noise can be reduced.

[0031] Specifically, the indoor unit housing 10 in this embodiment further includes an air inlet panel 12, which is located at the top of the indoor unit housing 10; the distance between the end of the pump body 20 close to the air inlet panel 12 and the air inlet panel 12 is H1, and the height of the indoor unit housing 10 is H, 1 / 7

[0032] Specifically, the filter assembly 50 in this embodiment can be movably arranged on the indoor unit housing 10, and the filter assembly 50 has a filtering position and a cleaning position. When the filter assembly 50 is in the filtering position, the filter assembly 50 is arranged relative to the air inlet, so that the air at the air inlet of the air inlet panel 12 is filtered through the filter assembly 50. When the filter assembly 50 is in the cleaning position, the filter assembly 50 moves to a position parallel to the installation panel 11. Specifically, when the filter assembly 50 is in the cleaning position, the cleaning head of the cleaning structure is arranged toward the filter assembly 50, so that the filter assembly 50 can be fully and effectively cleaned by the cleaning head of the cleaning structure. The water tank 60 is arranged in the indoor unit housing 10, and the water tank 60 is connected to the pump body 20. The water tank 60 and the pump body 20 are both located at the end of the filter assembly 50. With such a structural arrangement, on the one hand, it is convenient for the water tank 60 to provide water to the pump body 20, where the pump body 20 mainly refers to the booster pump. On the other hand, it can optimize the structural layout of the components inside the indoor unit housing 10, improve the compactness of the structure, reduce the overall size of the air conditioner indoor unit, optimize the overall appearance, and miniaturize the whole machine.

[0033] ​In this embodiment, the air conditioner indoor unit also includes a water receiving trough. When the filter assembly 50 is in the cleaning position, the water receiving trough is located below the filter assembly 50, so as to receive water flowing down from the filter assembly 50 through the water receiving trough, thereby preventing water from dripping onto other components in the indoor unit housing 10, thereby effectively ensuring safety of use.

[0034] Specifically, the air conditioner indoor unit in this embodiment further includes an electrical box 70, which is disposed in the indoor unit housing 10, and is located at one end of the filter assembly 50, and the water tank 60 and the pump body 20 are both located at the other end of the filter assembly 50. With such a structural arrangement, the internal structure layout of the air conditioner indoor unit can be further optimized, the compactness of the internal structure of the indoor unit housing 10 can be further improved, and the overall layout can be optimized.

[0035] In this embodiment, the water tank 60 includes a first box body 61 and a second box body 62, the first box body 61 and the second box body 62 are connected, and the first box body 61 is protruded from the side of the second box body 62, so that the overall water tank 60 is L-shaped. The first box body 61 is located at the side of the pump body 20, and the second box body 62 is located at the upper part of the pump body 20. With such a structural arrangement, the structure of the water tank 60 can be fully optimized, and the capacity of the water tank 60 can be increased, so as to provide sufficient cleaning water source for the cleaning structure. In addition, with such a structural arrangement, the space can be fully utilized, the void ratio can be reduced, and the spatial layout can be optimized.

[0036] The sound insulation component is disposed in the indoor unit casing 10 , and at least a portion of the sound insulation component is wrapped around the pump body 20 , so as to reduce the noise of the pump body 20 through the sound insulation component.

[0037] With the air conditioner indoor unit provided in this embodiment, the pump body 20 provides a cleaning water source with sufficient water pressure to the cleaning structure, so that the cleaning structure can fully clean the parts in the indoor unit housing 10, so as to maintain the cleanliness of the parts inside the indoor unit housing 10, thereby facilitating the improvement of the comfort of use of the air conditioner indoor unit. At the same time, since at least part of the sound insulation component is wrapped on the pump body 20, the noise generated by the operation of the pump body 20 can be effectively reduced, thereby solving the technical problem of high noise in the air conditioner indoor unit in the prior art.

[0038] Specifically, the pump body 20 in this embodiment is a booster pump, which increases the cleaning water source with sufficient water pressure to the cleaning structure through the booster pump, so as to ensure the cleaning effect of the cleaning structure.

[0039] In this embodiment, the sound insulation component includes sound insulation cotton 30 , and the sound insulation cotton 30 is wrapped on the pump body 20 to reduce the noise of the pump body 20 through the sound insulation cotton 30 .

[0040] Specifically, the sound insulation assembly in this embodiment further includes a mounting pad 40, which is provided with a mounting hole. The mounting pad 40 is provided on the pump body 20 so that the pump body 20 is installed on the indoor unit housing 10 through the mounting pad 40. Specifically, during the installation process, the connector is connected to the indoor unit housing 10 through the mounting hole to improve the stability of the connection. The mounting pad 40 is made of an elastic material. With such a structural setting, the connection is made through the elastic material, which can effectively play a buffering role, thereby effectively reducing the noise generated by vibration.

[0041] Preferably, the mounting pad 40 in this embodiment is a rubber pad, so that the rubber pad can effectively play a shock-absorbing and buffering role to reduce the situation where the pump body 20 transmits noise to the indoor unit casing 10 due to vibration.

[0042] This patent provides a layout and noise reduction solution for a booster pump with a filter cleaning function for a wall-mounted machine. The reasonable layout of the booster pump can reduce the size of the entire machine and increase the volume of the water tank 60 while reducing the noise caused by different layouts of the booster pump. In addition, the booster pump is specially wrapped with sound insulation cotton 30 and installed with rubber pads, which plays a role in the noise reduction design of the booster pump and can improve the comfort and usability of the entire machine.

[0043] Figure 1 This is a layout diagram of the water washing structure of the wall-mounted machine filter. First, the condensed water is collected by the water receiving tray, and the condensed water after passing through the filter 90 is sent to the water tank 60 by the water pump 80. The condensed water must pass through the filter 90 during the extraction process. The purpose is to filter the condensed water to prevent impurities in the condensed water from clogging the water pump 80 and the subsequent water nozzles. After the water tank 60 is full of condensed water, the booster pump uses the water in the water tank 60 and sends it to the nozzle in front of the filter through the boost of the booster pump to clean the filter.

[0044] The booster pump is on one side of the whole machine. In order to reduce the size of the whole machine, the booster pump can be arranged with the booster pump head facing downward or with the booster pump head facing upward. Through experimental tests, the vibration amplitude of the booster pump is reduced by 0.23g and the noise is reduced by 1.2dB(A) when the booster pump head is facing downward compared with the booster pump head facing upward. At the same time, in order to ensure the volume of the water tank 60 and thus the amount of water for washing and cleaning the filter screen, its layout position is as follows: Figure 2 As shown, the center of the booster pump is placed at a distance L1 from the rear side of the wall-mounted machine, where the thickness of the whole machine is L, then 1 / 6L<L1<3 / 4L, and the distance between the upper edge of the booster pump and the top of the whole machine is H1, where the height of the whole machine is H, then 1 / 7H

[0045] Experimental testing Booster pump head downward Booster pump head upward Vibration amplitude / g (g: gravitational acceleration) 0.81 1.04 Noise / dB(A) 57.3 58.5

[0046] ​Specifically, the booster pump assembly is composed of a pump body 20, sound insulation cotton 30 and a mounting rubber pad, and the pump body 20 is provided with a water inlet 21 and a water outlet 22. The booster pump is wrapped with sound insulation cotton 30 to reduce the radiation of the booster pump noise, and the booster pump is installed with a rubber pad to reduce the noise transmitted to the whole machine housing due to vibration of the booster pump.

[0047] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: reduce the noise of the pump body in the wall-mounted machine, change the fluid path of the pump body, improve the effective layout of the pump body, effectively clean the filter assembly, and increase the air volume of the filter assembly, so as to improve the comfort and usability of the whole machine.
