It should be understood that these embodiments are provided so that the disclosure of this application is thorough and complete, and the concept of these exemplary embodiments is fully conveyed to those of ordinary skill in the art. In the drawings, for clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to denote the same devices, and thus their description will be omitted.

[0037] Combined with Figures 1 to 5 As shown, according to a specific embodiment of this application, an indoor unit is provided.

[0038] Specifically, the indoor unit includes a housing 10, a cleaning device 20, a blower fan 30, and an evaporator 90. The evaporator 90 is disposed within the housing 10. The blower fan 30 is disposed within the air duct 11 of the housing 10. The cleaning device 20 is disposed within the housing 10. The cleaning device 20 has a cleaning nozzle 21. The cleaning nozzle 21 is movably disposed relative to the housing 10, and the cleaning nozzle 21 is used to spray a cleaning liquid to clean the air duct 11, the evaporator 90, and the blower fan 30.

[0039] In this embodiment, by disposing a cleaning device within the housing of the indoor unit and arranging the cleaning nozzle of the cleaning device in a movable manner, the evaporator, the air duct, and the blower fan on the air duct can be simultaneously cleaned by the cleaning nozzle, so that the indoor unit can achieve a thorough cleaning in all directions, effectively improving the cleaning efficiency of the indoor unit.

[0040] Among them, the cleaning device 20 includes a water tank 22 and a power source 23. The water tank 22 is arranged inside the housing 10. The water tank 22 has a first water inlet 221. The first water inlet 221 is used to collect the condensed water inside the housing 10. The power source 23 is arranged inside the housing 10. The inlet end of the power source 23 is communicated with the outlet end of the water tank 22, and the outlet end of the power source 23 is communicated with the cleaning nozzle 21 through a hose 24. In this embodiment, the power source 23 can be a water pump, and the water pump can be arranged in the air duct. For the indoor unit with this structure, the cleaning device 20 can automatically spray and clean the evaporator, air duct and air blades inside the air conditioner, realizing the self-cleaning of the air conditioner.

[0041] The cleaning nozzle 21 is arranged between the evaporator 90 and the air duct 11. There can be multiple cleaning nozzles 21, and each cleaning nozzle 21 is correspondingly provided with a hose 24. Each cleaning nozzle 21 independently slides along a preset direction for cleaning operations. As Figure 2 shown, the cleaning nozzle 21 can slide up and down in the vertical direction along the axial direction of the air duct, completely covering the air duct to achieve full-range cleaning.

[0042] As Figure 3 shown, the indoor unit further includes an upper water receiving tray 40 and a lower water receiving tray 80. The lower water receiving tray 80 is connected to the housing 10. The water tank 22 is connected to the lower water receiving tray 80. The upper water receiving tray 40 is connected to the housing 10 and is located above the lower water receiving tray 80. A part of the evaporator 90 extends into the upper water receiving tray 40, and the first water inlet 221 is communicated with the water receiving groove of the upper water receiving tray 40 through a connecting pipe 50. Such a setting can facilitate the discharge of the liquid water accumulated at the upper water receiving tray 40 into the water tank 22.

[0043] Further, the connecting pipe 50 has a first channel and a second channel. The first water inlet 221 is communicated with the water receiving groove of the upper water receiving tray 40 through the first channel. A control valve 51 is arranged in the second channel. The control valve 51 has an open position for opening the second channel and a closed position for closing the second channel. When the control valve 51 is in the open position, the condensed water in the water receiving groove of the upper water receiving tray 40 flows into the lower water receiving tray 80 through the second channel. Such a setting can control the working state of the control valve 51 according to the amount of liquid water in the upper water receiving tray 40. The control valve 51 is preferably an electric switch. For example, when the air conditioner is in the cooling mode, the electric switch is closed, the first water inlet 221 of the water tank is opened, the condensed water flows into the water tank, and the water storage starts. When the water in the water tank is full or the cleaning mode is turned on, the electric switch is opened, and the condensed water or the waste water after cleaning the air conditioner falls into the lower water receiving tray from the drain nozzle and then is directly discharged.

[0044] As Figure 4 and Figure 5As shown, the indoor unit further includes a first evaporator bracket 60 and a second evaporator bracket 70. The first evaporator bracket 60 is of an arc structure. Both ends of the first evaporator bracket 60 are connected to the housing 10. An opening 61 is provided on the side of the first evaporator bracket 60 facing the air duct 11. The second evaporator bracket 70 is connected to the first evaporator bracket 60, and the second evaporator bracket 70 is detachably disposed at the opening 61. This arrangement allows the interior of the indoor unit to be cleaned manually by opening the second evaporator bracket 70.

[0045] To improve the stability and reliability of the cleaning nozzle 21 during movement, a guiding part and a driving part are further provided in the indoor unit. The guiding part is disposed inside the housing 10. The cleaning nozzle 21 is connected to the guiding part. The driving part drives the cleaning nozzle 21 to reciprocate along the axial direction of the air duct 11. Among them, the guiding part can be a guide rail or a guiding groove, and the driving part can be a motor-gear assembly, that is, a rack can be provided inside the housing, and the motor drives the rack to drive the cleaning nozzle 21 to reciprocate along the guiding part.

[0046] Furthermore, the water tank 22 has a second water inlet for connecting to an external water source. This arrangement enables the introduction of an external water source to clean the indoor unit when the water in the water tank 22 is insufficient.

[0047] As Figure 2 shown, the air blades 30 are cross-flow air blades. There are two cross-flow air blades arranged side by side. The cleaning nozzle 21 is located between the two cross-flow air blades, and the cleaning nozzle 21 is slidably arranged along the axial direction of the cross-flow air blades. One cleaning nozzle 21 is correspondingly provided for each cross-flow air blade. This arrangement can improve the cleaning efficiency of the cleaning device.

[0048] The indoor unit in the above embodiment can be used in the technical field of air conditioning equipment. That is, according to another aspect of the present invention, an air conditioner is provided, including an indoor unit, and the indoor unit is the indoor unit in the above embodiment.

[0049] Specifically, the present application provides an air conditioner with all-round self-cleaning. Through the built-in water pump and cleaning nozzle, the evaporator, air duct and air blades inside the air conditioner are comprehensively cleaned, which is beneficial to the efficient refrigeration of the air conditioner and the health of users. At the same time, it can recycle waste water, enabling the reuse of waste water, making the indoor unit more economical and environmentally friendly.

[0050] The self-cleaning device provided by this application is composed of a water tank, a water pump, a rubber hose, and a cleaning nozzle. The water tank is located on the lower side of the water receiving tray of the air conditioner, used to collect the condensed water generated by the air conditioner during refrigeration, and can also be externally connected to a water pipe for manual water injection outside the machine. The water pump is located on the side of the water tank, used to provide power during water spraying, and is connected to the water pump through a water pipe. There are a total of two nozzles for the cleaning nozzle, and the two nozzles are respectively connected to the water pump through rubber hoses. When the self-cleaning device is working, the water pump pumps out the water in the water tank, and the nozzles spray the water onto the inner side of the air duct to achieve the cleaning purpose. The two nozzles of the cleaning nozzle are respectively placed in the middle of the two air ducts of the dual-duct air conditioner, spraying water from the middle to both sides. The spraying angle of the nozzles covers the evaporator, the air duct, and the air blades. In addition, the nozzles can slide up and down along the air duct to achieve the purpose of completely cleaning the air duct.

[0051] The evaporator bracket of this application is separable and is composed of a first evaporator bracket and a second evaporator bracket. The two evaporator brackets are fixed together by two screws. The second evaporator bracket can be directly disassembled from the top of the indoor unit, facilitating manual cleaning of the indoor unit with another water gun. Through the opening of the second evaporator bracket, the evaporator, the air duct, and the air blades inside the air conditioner can be further rinsed. In actual use, the user only needs to disassemble the top cover of the air conditioner and then disassemble the second evaporator bracket to rinse the air conditioner, without the need to completely disassemble the whole machine for cleaning. The disassembly and assembly are convenient, and the cleaning efficiency is higher.

[0052] For the sake of convenience in description, spatial relative terms such as "above...", "over...", "on the upper surface of...", "upper...", etc. can be used here to describe the spatial position relationship between a device or feature shown in the figure and other devices or features. It should be understood that the spatial relative terms are intended to include different orientations in use or operation in addition to the orientation described in the figure for the device. For example, if the device in the figure is inverted, the device described as "above other devices or structures" or "over other devices or structures" will then be positioned as "below other devices or structures" or "under other devices or structures". Thus, the exemplary term "above..." can include both the orientations of "above..." and "below...". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and corresponding interpretations should be made for the spatial relative descriptions used here.

[0053] In addition to the above, it should be noted that the "one embodiment", "another embodiment", "embodiment", etc. mentioned in this specification refer to the specific features, structures or characteristics described in connection with that embodiment being included in at least one embodiment generally described in this application. The same expression appearing in multiple places in the specification does not necessarily refer to the same embodiment. Further, when describing a specific feature, structure or characteristic in connection with any one embodiment, it is intended that implementing such feature, structure or characteristic in connection with other embodiments also falls within the scope of the present invention.

[0054] In the above embodiments, the descriptions of the respective embodiments have their own emphases. For parts not detailed in a certain embodiment, reference may be made to the relevant descriptions of other embodiments.

[0055] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
