For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] The following is a further detailed description of an automatic cleaning device for an air conditioning filter of the present invention in conjunction with the accompanying drawings.

[0039] Combined with Figure 1-13 , the present invention is introduced in detail.

[0040] An automatic cleaning device for an air conditioner filter comprises a water tank 1, a water spraying assembly, a brushing assembly, a wind speed detection assembly and a control panel. The water tank 1 is provided with a water injection port for adding water into the water tank 1; the water spraying assembly is connected to the lower part of the water tank 1, and draws water to the water sprayer 3 through a water pump 2, and the water sprayer 3 is arranged above the brushing assembly, and is used to spray cleaning water on the air conditioner filter; the brushing assembly is arranged on one side of the air conditioner filter, and comprises a telescope 6 and a cleaning brush 7, and the telescope 6 can be extended or contracted as needed, driving the cleaning brush 7 to brush the air conditioner filter; the wind speed detection assembly is arranged at the air inlet of the air conditioner, and determines whether the air conditioner is in a normal working state by detecting the wind speed. Once the wind speed is detected to be lower than the normal threshold, the water spraying assembly and the brushing assembly are triggered to start the cleaning process; the control panel, as the center of the entire device, is responsible for receiving the signal of the wind speed detection assembly and controlling the working state of the water spraying assembly and the brushing assembly.

[0041] The water spray assembly of the present invention includes a water pump 2 and a water sprayer 3, which are connected by a water inlet pipe 4 and a water outlet pipe 5 to form a complete water pumping and water spraying system. The water sprayer 3 and the brush cleaning assembly are detachably connected to facilitate maintenance and replacement. The end of the telescopic device 6 of the brush cleaning assembly is connected to a mounting frame 8, and the cleaning brush 7 is installed on the mounting frame 8. The telescopic device 6 and the cleaning brush 7 are controlled by the control panel to realize the extension and extension of the telescopic device 6 and the rotation of the cleaning brush 7, thereby completing the comprehensive cleaning of the air conditioning filter.

[0042] The wind speed detection component consists of a wind speed wheel 9, a wind speed rod 10, a signal and control line 11, an air duct 12 and a damper 13. The air duct 12 is arranged at the air inlet of the air conditioner, and the damper 13 is arranged on the air duct 12. The wind speed wheel 9 is arranged on the damper 13 of the air duct 12, and can sense the wind speed changes when the air conditioner is running; the wind speed rod 10 is responsible for converting the wind speed signal into an electrical signal, and transmitting it to the control board through the signal and control line 11; the damper 13 can be opened and closed, which is convenient for timed detection of wind speed and can extend the service life of the wind speed wheel 9.

[0043] In addition, the water inlet of the present invention is also provided with a pure water filling port 14 and a condensed water inlet 15, which are respectively used for manual water addition and automatic collection of condensed water from the air conditioner for reuse. An upper water level sensor 16 and a lower water level sensor 17 are also provided in the water storage tank 1, which are respectively used to detect whether the water storage tank 1 is full of water or lacking water, so as to ensure the normal operation of the device.

[0044] The condensed water discharge components include an evaporator water tank 18, a condensed water tee 19, a filter 20, and a solenoid valve 21, etc., which can automatically collect and filter the condensed water of the air conditioner, and inject the clean condensed water into the water storage tank 1 for washing through the control of the solenoid valve 21. In order to prevent the condensed water from breeding bacteria during the storage process, the present invention is also provided with a preservative filler 22, which can regularly add preservatives to the condensed water.

[0045] The preservative filler 22 consists of a kettle body 34, a preservative filling port 28, a water float 29, a preservative tube 30, a thin water tube 31, and a thick water tube 32. The kettle body 34 serves as the main carrier, containing condensed water and preservatives, which can be used to dissolve the preservatives to form an preservative solution. The preservative is fed into the preservative filler 22 from the preservative filling port 28. The water float 29 is in the kettle body 34 and is rotatably connected to the side wall of the kettle body 34, floating on the preservative solution. The thin water tube 31 and the thick water tube 32 are both arranged on the side wall of the kettle body 34, for discharging the preservative solution. The ends of the two are connected by an antiseptic water tee 33. The antiseptic water tee 33 is also connected to the water pipe so that the end of the water pipe is connected to the condensation water inlet 15, so that the condensed water with antiseptic measures is discharged into the water storage tank 1 to avoid the condensed water from generating odor due to long-term storage.

[0046] In order to collect the sewage generated during the cleaning process, the present invention is provided with a cleaning net water tank 23 below the air conditioner filter, and a drain port 24 is provided at the bottom to facilitate the discharge of sewage. At the same time, an overflow pipe 25 is also provided on the condensate water tee 19, which can directly guide the excess condensate water into the cleaning net water tank 23 to avoid water accumulation.

[0047] In order to ensure that the brushing component does not exceed the boundary of the air conditioning filter during the cleaning process, the present invention also provides an upper limiter 26 on one side of the air conditioning filter and a lower limiter 27 on the other side to limit the movement range of the brushing component.

[0048] The specific implementation process of the automatic cleaning device for air conditioner filter of the present invention is as follows:

[0049] The automatic cleaning device for the air conditioner filter of the present invention uses a brush and water to clean the dust and discharge it into the room. The operation process is as follows:

[0050] When the filter is dirty to a certain extent, the wind speed detection component (wind speed sensor) will judge by the air volume and send a signal that needs to be cleaned to the control panel. When cleaning is needed, the cleaning process is started. During cleaning, the sprinkler 3 sprays water on the filter, and the cleaning brush 7 brushes at the same time. The water in this cleaning system needs to be manually added with pure water through the pure water filling port 14 during the initial installation. Later, when it is short of water, according to the operating mode, the air conditioning condensate water is processed and stored in the kettle body 34 under cooling conditions. In order to store the condensate water for a long time without deterioration, a preservative filler 22 is added to the system, and an equal proportion of preservatives are added to the air conditioning condensate water during the storage process to ensure that the cleaning water does not deteriorate. The water storage capacity can be used for cleaning in cooling, heating and other modes.

[0051] Water shortage and condensate filling, cleaning brush and water spray, air volume detection and judgment are all realized through the control board. The circuit schematic diagram of the relevant control is as attached. Figure 6-13 shown.

[0052] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
