Description

Technical Field

[0001] This utility model relates to the field of air conditioner filter screen cleaning technology, specifically to an air conditioner filter screen cleaning unit, immersion chamber, and integrated cleaning equipment. Background Technology

[0002] Nowadays, air conditioners are widely used in residential buildings, office buildings, factories, hospitals, and schools. The air conditioner filter is a crucial part of filtering dust within the air conditioner. After prolonged use, a lot of dust accumulates on the filter, affecting the air conditioner's performance. Therefore, to ensure optimal air conditioner performance, the air conditioner filter needs to be cleaned regularly.

[0003] Currently, most household air conditioner filters are cleaned manually, while commercial or industrial air conditioner filters require professional air conditioner filter cleaning equipment.

[0004] Chinese utility model patent CN216935082U discloses an integrated device for cleaning, drying, and disinfecting central air conditioning filters. This device combines the functions of cleaning, drying, and disinfecting air conditioning filter screens. Its drawback is that the cleaning mechanism uses a spray method to clean the air conditioning filter screens, resulting in a relatively poor cleaning effect. Summary of the Invention

[0005] This invention provides a cleaning unit, immersion chamber, and integrated cleaning equipment for air conditioning filter screens, thereby solving the technical problem that the existing technology of cleaning air conditioning filter screens by spraying has poor cleaning effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution.

[0007] On the one hand, a cleaning unit for an air conditioner filter screen is provided. The cleaning unit includes multiple rotating shafts arranged in parallel along a first direction. The rotating shafts are driven to rotate by a first driving mechanism. Each rotating shaft has multiple eccentric wheel columns along its axial direction. The outer surface of each eccentric wheel column is covered with foamed silicone.

[0008] Compared to spraying, this invention utilizes two cleaning units to clamp the air conditioning filter screen. During the immersion washing process, a first drive mechanism drives the two side rollers to repeatedly rub and wash the air conditioning filter screen, resulting in a better cleaning effect. Secondly, the eccentric rollers provide a non-constant thrust and kneading motion similar to a cam, while the flexibility and high coefficient of friction of the foamed silicone convert this mechanical motion into an effective dirt-removing force, while avoiding damage to the filter screen from hard scraping. The combination of these two aspects achieves a "powerful yet gentle" cleaning effect. Furthermore, the eccentric rollers can also adapt to air conditioning filter screens of different thicknesses.

[0009] On another front, an immersion chamber for an air conditioning filter screen is provided. The top of the immersion chamber has a first inlet, the side has a first outlet, and the first outlet has an electric gate. Multiple cleaning units as described above are spaced apart along a second direction inside the immersion chamber. The first direction and the second direction are located on the same horizontal plane and are perpendicular to each other.

[0010] Therefore, by setting up multiple cleaning units in the immersion chamber, this invention can complete the cleaning of multiple air conditioning filter screens in one go, thereby improving work efficiency.

[0011] On another front, an integrated air conditioning filter cleaning device is provided, comprising a clean water tank, an immersion chamber, a rinsing chamber, a dehydration chamber, a controller, and the aforementioned immersion chamber; wherein the immersion chamber, the rinsing chamber, and the dehydration chamber are connected sequentially along a first direction;

[0012] The clean water tank and the immersion chamber are connected by a water supply pipe;

[0013] The flushing chamber is provided with a pair of cleaning units spaced apart along the second direction. The pair of cleaning units together form a flushing station. A water spray gun is provided on the outside of the flushing station.

[0014] The dehydration chamber is driven to rotate by a second drive mechanism, and a second inlet is provided on the side wall of the dehydration chamber;

[0015] The first outlet, the rinsing station, and the second inlet form a channel for conveying the air conditioning filter screen;

[0016] The controller is communicatively connected to the electric gate, the first drive mechanism, and the second drive mechanism.

[0017] Therefore, this invention can automate the soaking, rinsing, and dehydration of multiple air conditioning filter screens in one operation, thereby improving work efficiency. Furthermore, existing technologies typically use different modules (such as rollers and nozzles) for conveying and cleaning, resulting in complex structures and large space requirements. The cleaning unit provided by this invention combines clamping and conveying with rubbing and cleaning functions, resulting in a simpler structure, smaller space requirements, and reduced overall system cost.

[0018] In some embodiments, a pre-drying chamber is provided between the rinsing chamber and the dehydration chamber. A pair of cleaning units are spaced apart in the pre-drying chamber along the second direction. The pair of cleaning units constitute a pre-drying station. The two ends of the pre-drying station are respectively connected to the rinsing station and the second inlet.

[0019] By setting up a pre-drying chamber between the rinsing chamber and the dehydration chamber, a pre-drying operation is achieved before dehydration, thereby shortening the dehydration time. Secondly, the cleaning unit provided by this utility model also has the function of squeezing and absorbing water.

[0020] In some embodiments, the system further includes a wastewater purification tank. The bottom of the immersion chamber is provided with a first drain outlet, and an electric valve is provided at the first drain outlet. The bottoms of the rinsing chamber, the pre-drying chamber, and the dehydration chamber are all provided with second drain outlets. The first and second drain outlets are both connected to the inlet of the wastewater purification system. The outlet of the wastewater purification tank is connected to the clean water tank via a water pump. The electric valve and the water pump are respectively communicatively connected to the controller.

[0021] Wastewater can be recycled by using wastewater treatment ponds, thereby saving water used for cleaning.

[0022] In some embodiments, the immersion chamber is provided with a first cleaning unit, a second cleaning unit, a third cleaning unit and a fourth cleaning unit in sequence; the second cleaning unit and the third cleaning unit are respectively hinged to a first movable guide plate and a second movable guide plate at one end near the rinsing chamber via hinges;

[0023] The hinge is provided with an elastic element that gives the first and second movable guide plates a tendency to rotate in a first direction; or

[0024] The first movable guide plate is driven to rotate by the third drive mechanism, and the second movable guide plate is driven to rotate by the fourth drive mechanism. The third and fourth drive mechanisms are respectively connected to the controller.

[0025] By incorporating a movable guide plate, the guide plate, which is pushed open when the air conditioning filter screen is conveyed to the first outlet, can close other conveying channels, thereby preventing blockage caused by multiple air conditioning filter screens passing through the first outlet simultaneously. Furthermore, the movable guide plate can also be actively driven by a drive mechanism, thus enabling the active opening and closing of each channel.

[0026] In some embodiments, the diameter of the eccentric wheel column at one end of the second and third cleaning units near the flushing chamber is smaller than the diameter of the eccentric wheel column at the other end; the eccentric wheels column at the one end of the first and fourth cleaning units near the flushing chamber converge inward. This design facilitates the smooth transport of the air conditioning filter screen from the multi-channel immersion chamber to the single-channel flushing chamber.

[0027] To prevent damage to the air conditioning filter mesh due to mutual impact during dehydration, in some embodiments, the dehydration chamber is longitudinally divided into three sub-chambers. Each sub-chamber has a one-way valve plate at the end near the second inlet, with the opening direction pointing inwards. The one-way valve plate can automatically close after the air conditioning filter mesh enters the dehydration chamber, preventing the air conditioning filter mesh from being thrown out during dehydration.

[0028] In some embodiments, the dehydration chamber is provided with a top cover, the inner surface of which is equipped with an ultraviolet disinfection device; the inner wall of the dehydration chamber is coated with a light-reflecting film. Thus, the air conditioning filter screen is sterilized and disinfected simultaneously with dehydration.

[0029] In some embodiments, the cleaning unit is provided with pins at both ends, and the immersion chamber, rinsing chamber and pre-drying chamber are provided with slots at both ends that cooperate with the pins, and multiple slots are provided along the second direction.

[0030] This utility model has at least the following technical effects or advantages:

[0031] 1. Compared to spraying, this invention utilizes two cleaning units to clamp the air conditioning filter screen. During the immersion washing process, the first drive mechanism drives the two side rollers to repeatedly rub and wash the air conditioning filter screen, resulting in a better cleaning effect. Secondly, the eccentric rollers provide a non-constant thrust and kneading motion similar to a cam, while the flexibility and high coefficient of friction of the foamed silicone convert this mechanical motion into an effective dirt-removing force, while avoiding damage to the filter screen from hard scraping. The combination of these two aspects achieves a "powerful yet gentle" cleaning effect. Furthermore, the eccentric rollers can also adapt to air conditioning filter screens of different thicknesses.

[0032] 2. This invention can automate the soaking, rinsing, pre-drying, and dehydration of multiple air conditioner filter screens in one operation, thereby improving work efficiency. Furthermore, existing technologies typically use different modules (such as rollers, nozzles, and sponge rollers) for conveying and cleaning, resulting in complex structures and large space requirements. The cleaning unit provided by this invention combines clamping and conveying with rubbing and cleaning functions, resulting in a simpler structure, smaller space requirements, and reduced overall system cost.

[0033] 3. By setting up a movable guide plate, the movable guide plate, which is pushed open when the air conditioning filter screen is conveyed to the first outlet, can close other conveying channels, thereby preventing blockage caused by multiple air conditioning filter screens passing through the first outlet simultaneously. Furthermore, the movable guide plate can be designed to be actively driven by a drive mechanism, thereby realizing the active opening and closing of each channel.

[0034] 4. By designing multiple sub-compartments, damage to the air conditioning filter screens due to mutual impact during the dehydration process can be avoided.

[0035] 5. The one-way valve plate can automatically close after the air conditioning filter screen enters the dehydration chamber to prevent the air conditioning filter screen from being thrown out during the dehydration process.

[0036] 6. The ultraviolet disinfection device can sterilize and disinfect the air conditioner filter screen while dehydrating it. Attached Figure Description

[0059] See Figure 3 and 4 An integrated air conditioning filter cleaning device includes a clean water tank 1, an immersion chamber 2, a rinsing chamber 3, a pre-drying chamber 4, a dehydration chamber 5, and a controller. The immersion chamber 2, rinsing chamber 3, pre-drying chamber 4, and dehydration chamber 5 are connected sequentially along a first direction, with the clean water tank 1 located on the side and perpendicular to each other. Figure 3 From a visual perspective, the first direction is from left to right, and the second direction is from inside the paper to outside the paper.

[0060] in:

[0061] The clean water tank 1 is connected to the immersion chamber 2 via a water pipe and is used to supply water to the immersion chamber 2.

[0062] The immersion chamber 2 has a first inlet at its top. In fact, the top of the immersion chamber 2 is covered with a cover plate, on which are slots for inserting the air conditioning filter grille 8, i.e., the first inlet. A first outlet is located at the connection between the immersion chamber 2 and the flushing chamber 3, and an electric gate 22 is installed at the first outlet. Multiple cleaning units 7 are spaced apart along a second direction inside the immersion chamber 2. Each pair of cleaning units 7 forms an immersion station, which is aligned with the aforementioned slots, allowing the air conditioning filter grille 8 to be inserted from top to bottom into each immersion station.

[0063] A pair of cleaning units 7 are spaced apart in the second direction inside the flushing chamber 3. The pair of cleaning units 7 form a flushing station. A water spray gun 31 is provided on the outside of the flushing station.

[0064] A pair of cleaning units 7 are spaced apart along the second direction inside the pre-drying chamber 4, and the pair of cleaning units 7 constitute a pre-drying station.

[0065] The dehydration chamber 5 is driven to rotate by the second drive mechanism, and a second inlet is provided on the side wall of the dehydration chamber 5.

[0066] The first outlet, rinsing station, pre-drying station, and second inlet form a channel for conveying the air conditioning filter screen 8;

[0067] The controller is communicatively connected to the electric gate 22, the first drive mechanism, and the second drive mechanism. Specifically, the first drive mechanism and the second drive mechanism can be stepper motors. Figure 1 As shown, each rotating shaft has a double-layer synchronous gear at its upper end, and power is transmitted via belt. Each washing unit 7 has a power box at its top, with a stepper motor driving one of the gears on the rotating shaft as the drive wheel, and the other gears as driven wheels and synchronous transmission wheels, transmitting power via belt. The spin-drying chamber 5 can be driven by a drive motor located at its bottom. Furthermore, the spin-drying chamber 5 is essentially the same in structure as the spin-drying drum of a washing machine, and will not be described in detail further.

[0068] As a preferred embodiment, the system also includes a wastewater purification tank 6. The bottom of the immersion chamber 2 is provided with a first drain outlet 21, and an electric valve is installed at the first drain outlet 21. The bottoms of the pre-drying chamber 4 and the dehydration chamber 5 are both provided with second drain outlets 41. Both the first drain outlet 21 and the second drain outlet 41 are connected to the inlet of the wastewater purification tank 6. The outlet of the wastewater purification tank 6 is connected to the clean water tank 1 via a water pump. The electric valve and the water pump are communicatively connected to the controller.

[0069] More preferably, the cleaning unit 7 is provided with pins 74 at both ends, and the immersion chamber 2, the rinsing chamber 3 and the pre-drying chamber 4 are provided with slots 75 that cooperate with the pins 74 at both ends. Multiple slots 75 are provided along the second direction, so that the spacing between the cleaning units 7 can be adjusted to accommodate air conditioning filter screens 8 of different thicknesses.

[0070] Specifically, such as Figure 2 and Figure 5As shown, the immersion chamber 2 is equipped with four cleaning units, forming three immersion stations. The immersion chamber 2 contains a first cleaning unit 701, a second cleaning unit 702, a third cleaning unit 703, and a fourth cleaning unit 704, arranged sequentially. The second cleaning unit 702 and the third cleaning unit 703 are respectively hinged to a first movable guide plate 91 and a second movable guide plate 92 at their ends near the rinsing chamber 3 via hinges. The first movable guide plate 91 and the second movable guide plate 92 can rotate about their respective hinges. The first immersion station is formed between the first cleaning unit 701 and the second cleaning unit 702; the second immersion station is formed between the second cleaning unit 702 and the third cleaning unit 703; and the third immersion station is formed between the third cleaning unit 703 and the fourth cleaning unit 704. The hinges corresponding to the first movable guide plate 91 and the second movable guide plate 92 are equipped with elastic elements, such as return torsion springs, that give the first movable guide plate 91 and the second movable guide plate 92 a tendency to rotate in a first direction.

[0071] As an alternative, the first movable guide plate 91 can be driven to rotate by the third drive mechanism, and the second movable guide plate 92 can be driven to rotate by the fourth drive mechanism. The third and fourth drive mechanisms are respectively connected to the controller in communication. The third and fourth drive mechanisms can be stepper motors.

[0072] As a preferred option, such as Figure 5 As shown, the diameter of the wheel column at one end of the second cleaning unit 702 and the third cleaning unit 703 near the flushing chamber 3 is smaller than the diameter of the wheel column at the other end. The wheel columns at the one end of the first cleaning unit 701 and the fourth cleaning unit 704 near the flushing chamber 3 converge inward. The first movable guide plate 91 and the second movable guide plate 92 can also be driven to rotate by a stepper motor.

[0073] As a preferred option, such as Figure 13 and Figure 14 As shown, the dehydration chamber 5 is longitudinally divided into three sub-chambers 51. Each sub-chamber has a one-way valve plate 11 with its opening direction pointing inwards from the second inlet. Specifically, for example, four sets of thin iron wires can be used to divide the dehydration chamber into three sub-chambers 51. Each set of wires includes multiple wires arranged vertically side-by-side. The spacing between the wires is sufficient to prevent the air conditioning filter screen from penetrating into other sub-chambers. Figure 15 As shown. One end of the wire is connected to the inner wall of sub-compartment 51, and the other end is connected to the inner wall (both sides) or doorpost 101 (inner side) at the second entrance of dehydration compartment 5. The doorpost 101 is arranged vertically, dividing the second entrance into three sub-entrances, as shown. Figure 16 As shown.

[0074] As a preferred embodiment, the top of the dehydration chamber is equipped with a cover, and the inner surface of the cover is equipped with an ultraviolet disinfection device; the inner wall of the dehydration chamber is coated with a light-reflecting film.

[0075] During operation, the air conditioning filter screens 8 to be cleaned are first inserted into each immersion cleaning station through the first inlet. After closing the electric valve and electric gate 22, water is supplied to the immersion cleaning chamber 2 through the clean water tank 1, with the water at least covering the top of all the air conditioning filter screens 8. Then, the rotating shafts on both sides of each immersion cleaning station are controlled to rotate back and forth in opposite directions. The two rows of eccentric rollers 72 holding the air conditioning filter screens 8 rotate back and forth in opposite directions. Under the friction of the eccentric rollers 72 wrapped in elastic and flexible foamed silicone material, the air conditioning filter screens 8 make a slight back-and-forth movement in the water, and the dirt is strongly peeled off.

[0076] After immersion washing is completed, the electric valve is opened, and the water in the immersion washing chamber 2 flows into the sewage purification tank 6 through the first drain outlet 21. The electric gate is opened, and the controller sends a command to the first drive mechanism to control the rotating shafts on both sides of each immersion washing station to rotate sequentially, thereby conveying the air conditioning filter screens 8 in each immersion washing station to the flushing chamber in sequence.

[0077] During transport, such as Figure 6 As shown, when the air conditioning filter screen 8 in the first immersion cleaning station reaches the vicinity of the first outlet, it pushes open the first movable guide plate 91. The first movable guide plate 91, which is pushed open, abuts against the second movable guide plate 92, thereby closing the second immersion cleaning station. Since the second movable guide plate 92 is in a horizontal position at this time, the third immersion cleaning station is also closed, thereby preventing the air conditioning filter screen 8 in the second and third immersion cleaning stations from also causing blockage through the first outlet.

[0078] like Figure 7 As shown, when the air conditioning filter screen 8 in the second immersion cleaning station reaches the vicinity of the first outlet, the first movable guide plate 91 and the second movable guide plate 92 are placed in a horizontal position, the second immersion cleaning station is opened, and the first immersion cleaning station and the third immersion cleaning station are closed, thereby preventing the air conditioning filter screen 8 in the first immersion cleaning station and the third immersion cleaning station from also passing through the first outlet and causing blockage.

[0079] like Figure 8 As shown, when the air conditioning filter screen 8 in the third immersion cleaning station reaches the vicinity of the first outlet, it pushes open the second movable guide plate 92. The pushed-open second movable guide plate 92 abuts against the first movable guide plate 91, thereby closing the second immersion cleaning station. Since the first movable guide plate 91 is in a horizontal position at this time, the first immersion cleaning station is also in a closed state, thereby preventing the air conditioning filter screen 8 in the first and second immersion cleaning stations from also passing through the first outlet and causing blockage.

[0080] As an alternative, the first movable guide plate 91 can be driven to rotate by a third drive mechanism, and the second movable guide plate 92 can be driven to rotate by a fourth drive mechanism. The third and fourth drive mechanisms are communicatively connected to the controller, and both can be stepper motors. The direction of rotation is the same as described above and will not be repeated.

[0081] After the air conditioning filter screen 8 enters the flushing chamber 3 from the first outlet, the controller issues a command to rotate the shafts on both sides of the flushing station, thereby conveying the air conditioning filter screen in the flushing station to the pre-drying chamber. At the same time, the controller also issues a spray command to the water spray gun to flush the air conditioning filter screen.

[0082] After the air conditioning filter screen 8 enters the pre-drying chamber 4 from the rinsing chamber 3, the controller issues a command to rotate the shafts on both sides of the pre-drying station, thereby conveying the air conditioning filter screen in the pre-drying station to the dehydration chamber. During the clamping and conveying of the air conditioning filter screen 8, the eccentric rollers, whose surface is covered with soft, elastic and dry foamed silicone material, effectively wipe off and absorb a large number of water droplets on the screen surface through friction, thereby achieving pre-drying.

[0083] Once all the air conditioning filter screens 8 have entered the dehydration chamber 5, the controller issues a command to rotate the dehydration chamber 5, thereby dehydrating the air conditioning filter screens 8. After a preset dehydration time, the controller issues a command to stop the rotation of the dehydration chamber 5, and the entire cleaning process is completed.
