Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to a disinfecting and cleaning device for an air conditioner filter. Background Art

[0002] The central air conditioning filter (hereinafter referred to as the filter) is an important component of the central air conditioning system. Its main function is to filter dust, bacteria, viruses and other impurities in the air to ensure the cleanliness and sanitary quality of the air as much as possible. The filter is usually installed in the air supply duct of the central air conditioning system. It can filter and purify the air entering the air-conditioned area to prevent dust, bacteria and other impurities from entering the room, thereby protecting the indoor environment and personnel health. The filter structure generally includes an outer frame (used to fix the filter net), a filter net (common filter materials include fiber net, activated carbon layer, etc.), a frame support, etc. (to facilitate the support of the outer frame to be fixed in the air supply duct).

[0003] After the filter has been used for a period of time, its filter screen needs to be cleaned. The existing cleaning methods are mainly divided into water washing and air cleaning. Although the water washing method has a good effect, for some filter elements (filter screens) that are not conducive to water washing, water washing can easily cause damage to the filter element (such as paper filter element), and it is necessary to wait for the water to dry after cleaning, so there are certain disadvantages in practical application (if the metal frame support is not made of rust-proof materials, it is easy to rust after contact with water). In the current technology, the air cleaning method is generally to directly flush the dust adhering to the filter screen with high-flow air generated by air compressors, etc. In this way, dust and the like float in the air, which will cause environmental pollution and will also have more or less adverse effects on the respiratory health of the staff. Finally, whether it is water washing or air washing to clean the filter, it cannot disinfect the various components of the filter. After the subsequent reinstallation, the probability of the virus entering the room with the air supply duct of the air conditioner is increased, which will more or less have an adverse effect on the health of the indoor personnel.

[0016] Figure 1 , 2 As shown in , a ring-shaped hollow sealing pad is glued to the rear end of the sealing plate 21. The solenoid valve DC is a normally closed valve core solenoid valve. The upper end of the dust tank 5 is an open structure and is filled with water. The lower end of the hose 66 is located at the lower end of the dust tank 5. The lower shell 1 is located at the front end of the dust tank 5 and has a rectangular opening larger than the external size of the dust tank 5. The movable door 101 (the movable door 101 can be opened to take out the dust tank for water exchange) is hingedly installed on the left side of the opening. A one-way air valve 102 (which can exhaust the air in the lower shell) is installed at the front of the right end of the lower shell. When the push column of the electric push rod M3 is located at the left dead center, the distance between the inner side of the left top plate 62 and the right top plate 61 is greater than the width of the air conditioning filter 8. An electric hot air mechanism can also be installed in series between the upper end of the solenoid valve DC and the air storage tank of the air compressor through a pipeline. The power input terminals 1 and 2 of the power module A1 are connected to the two poles of the AC 220V power supply through wires, respectively. The 12 ultraviolet sterilization lamps H and the electric vacuum pump M1 are connected in series through power switches S1 and S2 and connected to the two poles of the AC 220V power supply through wires, the power output terminals 3 and 4 of the power module A1 are connected to the power input terminals 1 and 2 of the third power switch S3, the fourth power switch S4, and the fifth power switch S5 through wires, respectively. The power output terminals 3, 4 and 5, 6 of the two power switches S4 and S3 are connected to the positive and negative and negative and positive power input terminals of the electric push rod M3 and the motor reduction mechanism M2 through wires. The power output terminal of the power switch S5 is connected to the power input terminal of the solenoid valve DC through wires.

[0017] Figure 1 , 2As shown, after the AC 220V power supply enters the power input terminal of the power module A1, the 3rd and 4th pins of the power module A1 output a stable DC 12V power supply which enters the power input terminal of the power switches S3 and S4. When the air conditioning filter 8 of the present invention needs to be cleaned, the manual bolt 22 fixing the sealing plate 21 is loosened, and then the handle of the power switch S4 is toggled to the left, the 1, 2 feet and the 3, 4 feet of the power switch S4 are connected respectively, the positive and negative power input ends of the electric push rod M3 are energized, and its push column drives the left top plate (moving to the left) and the right top plate to open the distance (turn off the power switch after it is in place), the staff places the air conditioning filter 8 between the left top plate 62 and the right top plate 61, and then the handle of the power switch S4 is toggled to the right, the 1, 2 feet and the 5, 6 feet of the power switch S4 are connected respectively, the negative and positive power input ends of the electric push rod M3 are energized, and its push column drives the left top plate (moving to the right) and the right top plate to shorten the distance, clamp the two side ends of the air conditioning filter 8 and turn off the power switch S4, and then, by tightening the bolts, the sealing plate 21 is sealed and installed at the front end of the cleaning bin 2 (to prevent dust from escaping). After turning on the power switches of the solenoid valve DC, the ultraviolet sterilization lamp H, and the electric vacuum pump M1, the solenoid valve DC is energized to open the valve core, and the ultraviolet sterilization lamp H is energized to emit ultraviolet light (to sterilize the cleaning chamber 2). In this way, the high-flow air output by the air compressor air tank enters the flushing pipe 3 through the solenoid valve DC, and then is ejected at high speed from the multiple flushing holes 32 at the lower end of the flushing pipe 3, flushing the dust on the surface of the air conditioning filter 8 into the conical dust collecting shell 4, and the electric vacuum pump M1 is energized to generate negative pressure suction, so that the flushed dust can enter the dust collecting tank 5 through the hose, and the water in the dust collecting tank 5 absorbs the dust and then discharges the air to the outside (the one-way air valve ensures that the air in the lower shell can be discharged to the outside). In actual situations, after the staff member turns the handle of the power switch S3 to the left or right, the 1, 2 pins and the 3, 4 pins or the 5, 6 pins of the power switch S3 are connected respectively, so that the positive and negative or negative and positive polarity power input terminals of the motor reduction mechanism M2 will be energized, and the rotating shaft of the motor reduction mechanism M2 will drive the air conditioning filter 8 to rotate clockwise or counterclockwise (about 5 revolutions per minute), and the high-flow air output by the flushing pipe can flush and clean the surface of the air conditioning filter 8 at multiple angles (after the power switch S3 is turned off, the motor reduction mechanism M2 loses power and does not work). After the flushing, cleaning and disinfection of the air conditioning filter 8 is completed, the staff member turns off the power switches of the solenoid valve, motor reduction mechanism, electric vacuum pump, etc., and completes the entire cleaning and disinfection process. The subsequent staff can open the sealed door 21, turn the handle of the power switch S4 to the left, connect the 1, 2 and 3, 4 pins of the power switch S4 respectively, the positive and negative power input terminals of the electric push rod M1 are energized, and its push column drives the left top plate (moves to the left) and the right top plate to open the distance (turn off the power switch after it is in place), and the staff can remove the cleaned and disinfected air conditioning filter 8.

[0018] Figure 1 ,2 As shown above, the new type can flush and clean the rotating air-conditioning filter at multiple angles and play a role in disinfection and sterilization. The electric vacuum fan can extract the dust generated by flushing in real time, and then discharge the air into the atmosphere after washing with water, thereby preventing the dust generated in the cleaning of the prior art from being directly discharged into the atmosphere without being processed, which brings adverse effects on the environment and staff. Figure 2 Among them, each ultraviolet germicidal lamp has a power of 15W; the motor reduction mechanism M2 is a coaxial motor gear reducer with a power of 120W; the electric push rod M3 is a finished reciprocating electric telescopic rod with a power of 20W; the power module A1 is a finished AC to DC 12V switching power supply module; the solenoid valve DC power is 2W; the power of the electric vacuum pump M1 is 300W (including the volute, motor, and blades.
