DETAILED DESCRIPTION

[0023] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific embodiments of the utility model are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0024] This embodiment provides an air conditioner, such as Figure 1 and Figure 2 As shown, it includes a shell 100 and a fan 10 accommodated in the shell 100. The shell 100 is provided with a cleaning liquid storage component at a position higher than the fan 10. The cleaning liquid storage component includes an internally formed liquid storage cavity 234 and a liquid inlet 231. The liquid storage cavity 234 is connected to a liquid infusion tube 232, and the liquid infusion tube 232 extends toward the fan 10.

[0025] The air conditioner provided in this embodiment includes a housing 100 with an air duct formed inside, a fan 10 for providing air flow power, and a cleaning liquid storage member for storing cleaning liquid. The inner side of the cleaning liquid storage is connected to a liquid infusion tube 232 for conveying the cleaning liquid in the liquid storage chamber 234 to the fan 10 to clean its blades 11; the cleaning liquid storage member is higher than the fan 10, and accordingly, the liquid infusion tube 232 extends obliquely downward toward the fan 10, and the blades 11 of the fan 10 are in contact with the outlet of the liquid infusion tube 232. There is no obstruction between the liquid pipe openings 232a; when the blades 11 of the fan 10 need to be cleaned, cleaning liquid can be poured into the liquid storage chamber 234 through the liquid inlet 231. The cleaning liquid flows into the infusion tube 232 under the action of its own gravity, and flows obliquely downward along the infusion tube 232 to the blades 11 of the fan 10. Specifically, during the cleaning process, the fan 10 can be started as needed to allow the cleaning liquid to flow to all areas around the fan 10, thereby achieving comprehensive and effective cleaning of the blades 11. On the one hand, the cleaning process does not require disassembly of the shell 100, and only requires the cleaning liquid to be poured into the liquid storage chamber 234 through the liquid inlet 231 from the outside, which is highly convenient to operate; on the other hand, the setting of the infusion tube 232 can accurately guide the cleaning liquid to the blades 11 to ensure that the cleaning liquid effectively cleans the blades 11, thereby improving the cleaning effect of the blades 11 and reducing the ineffective waste of the cleaning liquid; on the other hand, the cleaning liquid storage component and the infusion tube 232 are both higher than the fan 10, and the cleaning liquid can clean the blades of the fan 10 under the action of its own gravity without the need for additional driving parts such as a pump body, thereby improving its structural simplicity.

[0026] Optionally, in this embodiment, if Figure 2 As shown, the housing 100 is provided with a return air inlet 120 at a position higher than the fan 10, the return air inlet 120 is blocked by a grille 200, and the cleaning liquid storage part is provided on the grille 200. The return air inlet 120 is higher than the fan 10, so the grille 200 blocking the return air inlet 120 and the cleaning liquid storage part provided on the grille 200 are both higher than the fan 10, thereby ensuring the self-cleaning of the fan 10; wherein, the cleaning liquid storage part is provided on the grille 200, and when the cleaning liquid storage part or the infusion tube 232 needs to be maintained, the grille can be disassembled and assembled, which is convenient to operate without additional disassembly and assembly of the housing 100.

[0027] Specifically, in this embodiment, Figure 2As shown, the bars of the grille 200 are hollow inside to form a liquid storage chamber 234. The grille 200 not only blocks the return air outlet 120 for protection, but also serves as a cleaning liquid storage component, which serves two purposes, thereby further improving its structural simplicity and functionality; in addition, a liquid storage chamber 234 is set inside the bars of the grille 200, a liquid inlet 231 is set on the bars, and a liquid infusion tube 232 is set inside the bars. On the basis of realizing self-cleaning of the blades 11 of the fan 10, the appearance of the exposed part of the grille 200 remains approximately unchanged, and the corresponding impact on the appearance structure of the air conditioner is relatively small, thereby improving the functionality of the air conditioner.

[0028] In addition, the cleaning liquid may be replaced with disinfectant, freshener, etc. and added into the liquid storage chamber 234 to disinfect and freshen the indoor air.

[0029] Specifically, Figure 2 As shown, the area inside the shell 100 for accommodating the heat exchanger 20 is the heat exchange area 130. The heat exchanger 20 is blocked on the upper side and the front side of the fan 10. The heat exchanger 20 is provided with a channel for the liquid infusion pipe 232 to pass through. The liquid infusion pipe 232 passes through the channel from top to bottom to reach the outside of the power area 110 where the fan 10 is installed; similarly, when the fan 10 has a casing, a through hole corresponding to the liquid outlet 232a of the liquid infusion pipe 232 is opened on the casing, so that the cleaning liquid output from the liquid outlet 232a can pass through and reach the blades 11 therein.

[0030] Optionally, in this embodiment, if Figure 2 As shown, the liquid outlet 232a of the liquid infusion tube 232 is not lower than the axis of the fan 10. In order to reduce the interference between the liquid infusion tube 232 and the blade 11, there is an avoidance gap between the liquid outlet 232a and the blade 11. On the one hand, compared with the case where the liquid outlet 232a is located on the horizontal side or below the fan 10, the cleaning liquid flowing out through the liquid outlet 232a needs to have a certain flow rate to flow through the above-mentioned avoidance gap to reach the blade 11. The liquid outlet 232a of this embodiment is located in the upper half of the fan 10. The cleaning liquid flowing downward through the liquid outlet 232a can definitely flow down to the blade 11, thereby ensuring the effective cleaning of the blade 11 by the cleaning liquid and reducing the occurrence of the situation where the cleaning effect of the blade 11 is poor due to ineffective falling when the flow rate of the cleaning liquid is low. On the other hand, the cleaning liquid flowing out through the liquid outlet pipe 232a first flows to the upper half of the blade 11, and then can flow from top to bottom through multiple areas of the blade 11 or even multiple blades 11, thereby increasing the contact and cleaning area between the cleaning liquid and the blade 11, and further improving the utilization of the cleaning liquid and its effectiveness in cleaning the blade 11; preferably, the liquid outlet pipe 232a is located directly above the fan 10 to ensure that the cleaning liquid fully cleans the blade 11 from top to bottom.

[0031] In this embodiment, Figure 3 and Figure 4As shown, there are multiple infusion tubes 232, and the outlets 232a of the multiple infusion tubes 232 are arranged at intervals along the axial direction of the fan 10. When the fan 10 is a cross-flow fan 10 or other fan with a certain axial length, the cleaning liquid is poured into the liquid storage chamber 234 through the liquid inlet 231, and the cleaning liquid in the liquid storage chamber 234 can flow downward through the multiple infusion tubes 232 at the same time, and flow to different axial regions of the blade 11 through the outlets 232a of each infusion tube 232, so as to fully clean the axial region of the blade 11.

[0032] Of course, in some other embodiments, when the blades 11 of the fan 10 do not have an axial length, such as the fan 10 in the form of a fan used in the outdoor unit of an air conditioner, the liquid outlet 232a of the infusion tube 232 may also be axially directed toward the blades 11.

[0033] Optionally, in this embodiment, if Figure 3 As shown, one of the bars of the grille 200 serves as a receiving bar 230, the length direction of the receiving bar 230 is consistent with the axial direction of the fan 10, the interior of the receiving bar 230 is hollow to form a liquid storage chamber 234, the liquid inlet 231 and multiple liquid infusion tubes 232 are all located in the receiving bar 230, and the multiple liquid infusion tubes 232 are arranged in parallel and spaced apart along the length direction of the receiving bar 230. One of the bars of the grille 200 is arranged to extend along the axial direction of the fan 10 as a receiving grille 230. The interior of the receiving grille 230 is hollow to form a long strip of liquid storage cavity 234. The receiving grille 230 and the liquid storage cavity 234 are approximately parallel to the blade 11. Accordingly, a plurality of liquid infusion tubes 232 of the same form can be arranged at intervals along the length direction of the receiving grille 230. On the basis of achieving cleaning of different axial regions of the blade 11, the liquid infusion tubes 232 can be mass-produced, and there is no need to distinguish the liquid infusion tubes 232 when connecting them to the receiving grille 230, thereby improving the processing convenience of the liquid infusion tubes 232 and the grille 200 and reducing their processing costs.

[0034] Specifically, in this embodiment, Figure 3As shown, the return air outlet 120 is rectangular and its length direction is consistent with the axial direction of the fan 10, and the grille 200 includes a plurality of cross-arranged horizontal bars 210 and a plurality of vertical bars 220, wherein the horizontal bars 210 extend along the length direction of the return air outlet 120, and one of the horizontal bars 210 serves as a receiving bar 230. The return air inlet 120 adopts a regularly shaped rectangular opening, and the grille 200 adopts a regularly shaped rectangular grille 200 accordingly, and the multiple horizontal bars 210 of the grille 200 extend along the length direction of the return air inlet 120 and are arranged at intervals along the width direction of the return air inlet 120, and the multiple vertical bars 220 extend along the width direction of the return air inlet 120 and are arranged at intervals along the length direction of the return air inlet 120. The processing accuracy and matching of the return air inlet 120 and the grille 200 can be better guaranteed; and the extension direction of the horizontal bar 210 is consistent with the axial direction of the fan 10. During processing, the accommodating bar 230 is used as one of the horizontal bars 210. On the basis of satisfying the need to transport cleaning liquid to clean the fan 10, the arrangement neatness of each bar of the grille 200 can also be improved.

[0035] In this embodiment, the accommodating bar 230 is located at the edge of the grille 200. The radial dimension of the accommodating bar 230 is larger than that of other horizontal bars 210 to realize the setting of the liquid storage chamber 234. The accommodating bar 230 is set at the edge of the grille 200, and the accommodating bar 230 is used as a frame bar in the frame of the grille 200. The ventilation area enclosed in the frame corresponds to the effective ventilation area of ​​the return air outlet 120, thereby reducing the shielding of the effective ventilation area of ​​the return air outlet 120 by the accommodating bar 200, and correspondingly ensuring the effective ventilation area of ​​the return air outlet 120, and ensuring the temperature regulation effect of the air conditioner; Figure 1 and Figure 2 As shown, the air conditioner is a wall-mounted air conditioner, and the return air outlet 120 is located at the top of the shell 100, wherein the length direction of the return air outlet 120 is consistent with the axial direction of the fan 10, and the accommodating bar 230 is located at the front edge of the grille 200 as a front frame bar of the grille 200; the number of infusion tubes 232 can be 10, and the 10 infusion tubes 232 are evenly spaced along the length direction of the accommodating bar 230; specifically, the length×width×depth of the liquid storage chamber 234 can be 600×20×20mm, and 240ml of cleaning liquid can be added to the liquid storage chamber 234 each time cleaning.

[0036] In this embodiment, the liquid inlet 231 is located outside the grid bar. When the fan 10 needs to be cleaned, the operator can clearly see the liquid inlet 231 from the outside and conveniently fill the cleaning liquid into the liquid inlet 231, thereby improving the convenience of the liquid filling operation and further improving the convenience of the cleaning operation.

[0037] Specifically, in this embodiment, Figure 3-Figure 5As shown, the liquid inlet 231 is connected to a liquid inlet nozzle 233 with an upward port, and the liquid inlet nozzle 233 is in a funnel shape with an expanded port in a direction away from the liquid inlet 231. The top port size of the liquid inlet nozzle 233 is larger than the liquid inlet 231, and the top port is arranged upward, so that the operator can pour the cleaning liquid into the liquid inlet nozzle 233 through the larger top port, and the cleaning liquid then flows into the liquid storage cavity 234 through the liquid inlet 231 under the guidance of the liquid inlet nozzle 233, thereby further improving the convenience of the liquid filling operation and reducing the waste caused by the outflow of the cleaning liquid during the liquid filling process.

[0038] Specifically, the diameter of the liquid inlet 231 may be 8 mm, and the inclination angle of the inner conical surface of the liquid inlet nozzle 233 may be 17.5°.

[0039] Preferably, the liquid inlet nozzle 233 is detachably sealed with a sealing plug. When cleaning is not required, the sealing plug can be used to seal the liquid inlet nozzle 233 to reduce the occurrence of dust and impurities entering the liquid inlet nozzle 233 to cause blockage of the liquid inlet port 231, the liquid storage chamber 234, etc., thereby ensuring its normal use; when the fan 10 needs to be cleaned, the sealing plug can be pulled out and cleaning liquid can be poured into the liquid storage chamber 234 through the liquid inlet nozzle 233.
