A cleaning device for an air conditioner filter

Abstract

This invention discloses a cleaning device for air conditioning filters, belonging to the field of filter cleaning technology. The invention includes a brushing mechanism for initial brushing of the air conditioning filter and a rinsing mechanism located at the bottom of the brushing mechanism, which performs a secondary rinse of the filter using airflow. In this invention, the brushing mechanism removes larger and harder stains from the filter beforehand, and the rinsing mechanism blows away loose dust and dirt, reducing the burden on subsequent ultrasonic cleaning. Finally, a deep cleaning mechanism removes fine particles, grease residue, and stubborn micro-contaminations from the filter. Because the filter surface has already had larger dirt and dust removed through brushing and airflow cleaning, ultrasonic cleaning can focus more on removing fine contaminants, achieving the best cleaning effect and reducing the burden and damage to the filter caused by prolonged ultrasonic cleaning. It also avoids excessive contamination of the cleaning fluid in the ultrasonic cleaner.

Description

Technical Field

[0001] This invention relates to the field of filter cleaning technology, and more specifically, to a cleaning device for air conditioning filters. Background Technology

[0002] When an air conditioner runs for extended periods, its filter filters the air. Over time, a large amount of dust accumulates inside, breeding bacteria, mold, and other harmful substances. Commercial air conditioning systems, factories, and central kitchens contain numerous air conditioners. These locations generate significant amounts of dust, grease, and other contaminants during operation, which quickly clogs the air conditioner filters. When the filters are clogged, the air conditioner's heating and cooling efficiency gradually decreases. Excessive internal dust hinders the normal operation of the air conditioner, affecting its cooling and heating performance. This not only harms human health but also increases energy consumption and shortens the air conditioner's lifespan.

[0003] Utility model patent CN221361605U discloses a filter cleaning device for air conditioner processing, including a cleaning chamber. A lifting unit is installed on the right side of the cleaning chamber, and a transport and recycling unit is installed at the bottom of the cleaning chamber. Ultrasonic transducers are installed on the outer surface of the cleaning chamber. This patent uses several ultrasonic transducers installed at the bottom and around the cleaning chamber to clean the surface dust of the filter through vibration. Although ultrasonic cleaning is an efficient and precise cleaning method, excessively dirty filters will increase the ultrasonic cleaning time. In particular, dust and stubborn dirt on the filter surface can cause damage to the filter due to prolonged vibration. It can also over-contaminate the cleaning solution, making filter cleaning inconvenient. Therefore, there is a need for an air conditioner filter cleaning device that can clean filters in batches. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a cleaning device for air conditioning filters.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] An air conditioner filter cleaning device, comprising:

[0007] A brushing mechanism is used for the initial brushing of air conditioning filters, removing stubborn stains and adhering substances from the filters. The brushing mechanism includes a feeding box, the bottom of which is connected to a discharge box. Two relatively rotating feeding rollers are installed inside the feeding box, with an inlet between the two rollers for the air conditioning filter to pass vertically through. Two supports are installed inside the discharge box, each with multiple brush heads rotatably mounted. The brush heads are evenly distributed with bristles to remove stubborn stains and adhering substances from the filters. The brush heads on the two supports are symmetrically arranged. A liquid-holding tank is installed inside each support, connected to the side wall of the discharge box via a pipe. Several liquid outlets connected to the liquid-holding tank are provided on the supports.

[0008] A discharge port is provided on one side of the feeding box. Two limiting holes are provided on the feeding box. Limiting wheels are rotatably installed in both limiting holes. The two limiting wheels are connected by a drive shaft and are located on the discharge port. A drive motor connected to the drive shaft is provided on one side of the feeding box. The limiting wheels contact the air conditioning filter and drive the air conditioning filter to move out of the discharge port, while fixing the air conditioning filter during the movement.

[0009] The rinsing mechanism is located at the bottom of the brushing mechanism. The rinsing mechanism uses airflow to perform a secondary rinse on the filter screen, quickly blowing away any loose dust and particles that were not completely removed from the filter screen. The rinsing mechanism includes a blower box and a rinsing box. The blower box delivers the generated airflow into the rinsing box, through which the filter screen is rinsed.

[0010] The deep cleaning mechanism is located at the bottom of the rinsing mechanism. The deep cleaning mechanism uses ultrasonic waves to perform deep cleaning of the filter screen, cleaning the surface of the air conditioning filter screen and the tiny stains in its gaps; the deep cleaning mechanism includes an ultrasonic cleaner, which is equipped with a material carrier frame for placing the filter screen.

[0011] The lifting mechanism is located on one side of the deep cleaning mechanism. It moves the filter between different mechanisms to clean and dry the filter.

[0012] As a further embodiment of the present invention, a rotating cover is rotatably installed on the rinsing box, the rotating cover is provided with multiple air outlets, and an electric heating wire is provided inside the rotating cover to heat the air inside the rotating cover. The rotating cover is connected to the blower box.

[0013] As a further embodiment of the present invention, a blower is provided inside the blower box, and rotating grooves are provided on both sides of the blower box for the rotating rod to pass through.

[0014] As a further embodiment of the present invention, two rotating rods are provided at the bottom of the rotating cover, and two guide rods are provided on one side of the material loading frame, with the two guide rods being movably connected to the two rotating rods respectively.

[0015] As a further embodiment of the present invention, an air duct is provided at the bottom of the feeding box, and the air duct is connected to the blower box at the bottom. Air enters the feeding box through the air duct and cleans the dust and dirt generated inside the feeding box due to brushing the filter screen.

[0016] As a further embodiment of the present invention, the feeding box is provided with a guide slope on the side facing the discharge port, and the inclination angle of the guide slope is set to 30-45°.

[0017] As a further embodiment of the present invention, both feed rollers are rotatably mounted in the feed box via rotating shafts, and drive gears are fixedly sleeved at the ends of both rotating shafts. The two drive gears mesh with each other, and a drive motor is provided on one side of the feed box. The output shaft of the drive motor is connected to one of the rotating shafts.

[0018] As a further embodiment of the present invention, the lifting mechanism includes a lifting seat, a lifting screw rotatably mounted on the lifting seat, a movable seat provided on one side of the material frame, the movable seat being threadedly connected to the lifting screw, a lifting motor for driving the lifting screw to rotate being provided on the top of the lifting seat, and the lifting seat being mounted on a fixed frame.

[0019] Compared with existing solutions, the beneficial effects of the present invention are as follows:

[0020] In this invention, a brushing mechanism removes larger and harder dirt from the filter screen in advance, and a rinsing mechanism blows away loose dust and dirt from the filter screen, reducing the burden on subsequent ultrasonic cleaning. Finally, a deep cleaning mechanism removes fine particles, grease residue, and stubborn micro-contaminations from the filter screen. Since the filter screen surface has already had larger dirt and dust removed through brushing and airflow cleaning, ultrasonic cleaning can focus more on removing fine contaminants, achieving the best cleaning effect. This reduces the burden and damage to the filter screen caused by prolonged ultrasonic cleaning, while also avoiding excessive contamination of the cleaning fluid in the ultrasonic cleaner, making filter screen cleaning more efficient and of higher quality.

[0021] By incorporating a brushing mechanism, the filter screen is vertically moved downwards using a feed roller, while the brush head simultaneously brushes and washes the screen during its movement, breaking down stubborn large stains and adhering substances. Meanwhile, a liquid-retaining tank within the support frame sprays cleaning fluid onto the brush bristles, providing initial cleaning of grease and contaminants on the filter screen. This mechanism is ideal for shopping malls, factories, central kitchens, and similar locations. Limiting wheels at the bottom of the brushing mechanism secure the air conditioning filter screen during movement, facilitating subsequent blowing and cleaning. Furthermore, a rinsing mechanism with a rotating cover, which blows away loose dust and dirt from the brushed filter screen, can also work in conjunction with a lifting mechanism to dry the filter screen on the loading frame, enhancing user convenience and versatility.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0030] Example 1

[0031] Reference Figures 1-6 As shown, the present invention is a cleaning device for an air conditioning filter, including a brushing mechanism 30. The brushing mechanism 30 is used for the initial brushing of the air conditioning filter to remove stubborn stains and adhering substances, especially grease or hardened dirt, from the filter.

[0032] The washing mechanism 30 includes a feeding box 31, with a discharge box 32 connected to the bottom of the feeding box 31. Two feeding rollers 33 are provided inside the feeding box 31, and a feeding port 34 for the air conditioning filter to pass vertically through is provided between the two feeding rollers 33. Both feeding rollers 33 are rotatably mounted in the feeding box 31 via rotating shafts 36. Drive gears 35 are fixedly sleeved at the ends of the two rotating shafts 36 and mesh with each other. A drive motor is provided on one side of the feeding box 31, and the output shaft of the drive motor is connected to one of the rotating shafts 36. Both drive gears 35 are provided in the protective housing. The drive motor drives the rotating shaft 36 to rotate, and the drive gear 35 at the end of the rotating shaft 36 meshes with the other drive gear 35, thereby driving the other rotating shaft 36 to rotate. The two rotating shafts 36 drive the two feeding rollers 33 to rotate relative to each other, so that the air conditioning filter can pass vertically through the feeding port 34 and fall into the discharge box 32.

[0033] The feeding box 32 is equipped with two supports 304, each with multiple brush heads 305 rotatably mounted on it. Each brush head 305 has bristles evenly distributed on it. Driven by a power source, the brush heads 305 rotate on the supports 304, using their bristles to brush and wash both sides of the air conditioning filter screen falling from the feed roller 33, removing stubborn stains and adhering substances. The brush heads 305 on the two supports 304 are symmetrically arranged. Each support 304 has a liquid collection tank 306 connected to the side wall of the feeding box 32 via a pipe. Several outlets connected to the liquid collection tank 306 are located on the supports 304. Cleaning liquid is introduced into the pipes on the side wall of the feeding box 32. When excessive grease adheres to the filter screen surface, the cleaning liquid is sprayed onto the bristle surface along the outlets, thus cleaning the grease on the filter screen surface in one pass, improving the cleaning effect and reducing the burden of subsequent ultrasonic cleaning. This method is suitable for cleaning air conditioning filters in kitchens and other work areas.

[0034] A discharge port 37 is provided on one side of the feeding box 32. A guide slope 38 is provided on the side of the feeding box 32 facing the discharge port 37. The inclination angle of the guide slope 38 is set to 30-45°, so that the air conditioning filter can be discharged from the discharge port 37 along the guide slope 38 after washing. Two limiting holes 39 are provided on the feeding box 32. Limiting wheels 301 are rotatably installed in the two limiting holes 39. The two limiting wheels 301 are connected by a drive shaft. The two limiting wheels 301 are set on the discharge port 37 for fixing and releasing the air conditioning filter. A drive motor is provided on one side of the feeding box 32. The output shaft of the drive motor is fixedly connected to the drive shaft. The drive motor drives the drive shaft to rotate, which in turn drives the two limiting wheels 301 to rotate. When the air conditioning filter moves to the discharge port 37 through the guide slope 38, the limiting wheels 301 contact the air conditioning filter and drive the air conditioning filter to move out of the discharge port 37. While moving the filter, the air conditioning filter is fixed, which facilitates the subsequent washing operation.

[0035] The bottom of the feeding box 32 is equipped with an air duct 303, which is connected to the blower box 21 at the bottom. By continuously inputting air into the feeding box 32, the dust and dirt accumulated on the guide slope 38 of the feeding box 32 are cleaned, so as to prevent the filter screen after washing from continuing to stick to dirt during the movement.

[0036] The rinsing mechanism 20 is located at the bottom of the brushing mechanism 30. The rinsing mechanism 20 performs a secondary rinsing of the filter screen through airflow. The airflow cleaning can quickly blow away loose dust and small particles that have not been completely removed, reducing the interference of impurities during ultrasonic cleaning.

[0037] At this point, the filter screen has already removed stubborn stains and most of the dust through the brushing mechanism 30, and the airflow cleaning can further clean away the dust that cannot be directly removed by brushing.

[0038] The rinsing mechanism 20 includes a blower box 21 and a rinsing box 22. The blower box 21 delivers the generated air to the rinsing box 22, and the filter screen is rinsed through the rinsing box 22. The blower box 21 and the rinsing box 22 are installed at the bottom of the feed box 32.

[0039] A rotating cover 23 is rotatably mounted on the rinsing box 22. The rotating cover 23 is provided with multiple air outlets 24. An electric heating wire is provided inside the rotating cover 23, which can heat the air inside the rotating cover 23. The rotating cover 23 is connected to the blower box 21 through an air pipe. Two rotating rods 25 are provided at the bottom of the rotating cover 23.

[0040] A blower 26 is installed inside the blower box 21. Rotating slots 27 are opened on both sides of the blower box 21 for the rotating rod 25 to pass through. By driving the rotating rod 25 to rotate, the rotating cover 23 is driven to rotate on the washing box 22, so that the air direction of the rotating cover 23 can be switched to different angles. The top of the blower box 21 is connected to the air duct 303 at the bottom of the feeding box 32. The air duct 303 can be used to clean the dust and dirt inside the feeding box 32, maintain the cleanliness of the feeding box 32, and prevent the filter screen from being re-adhered to dirt during movement, which would affect subsequent cleaning.

[0041] The deep cleaning mechanism 10 is located below the flushing mechanism 20. It utilizes ultrasonic waves to perform deep cleaning of the filter, employing the vibration effect of high-frequency sound waves to clean the surface and crevices of the air conditioning filter for tiny dirt. Through the cavitation effect generated by the vibration, it effectively removes fine particles, grease residue, and stubborn micro-contaminants from the filter. Ultrasonic cleaning can focus more intently on removing minute contaminants, achieving optimal cleaning results.

[0042] The deep cleaning mechanism 10 includes an ultrasonic cleaner 11. The ultrasonic cleaner 11 utilizes the vibration effect of high-frequency sound waves to clean the surface and crevices of the air conditioning filter, removing minute dirt. The ultrasonic cleaner 11 is equipped with a material carrier frame 12, and a movable seat 13 is located on one side of the material carrier frame 12. The movable seat 13 drives the lifting and lowering of the material carrier frame 12, thereby achieving the cleaning and drying of the filter. Two guide rods 14 are located on one side of the material carrier frame 12, and the two guide rods 14 are movably connected to two rotating rods 25 respectively. As the filter screen 12 moves upward, it moves out of the ultrasonic cleaner 11. At the same time, the two guide rods 14 abut against the rotating rod 25, causing the rotating cover 23 to rotate on the rinsing box 22. The air outlet 24 of the rotating cover 23 faces the filter screen 12. The fan 26 delivers air into the rotating cover 23, which is heated by the heating wire to dry the filter screen in the filter screen 12. The air in the rotating cover 23 is generally heated to 40-60℃, which will not cause the filter screen to overheat and change the filter screen material.

[0043] Lifting mechanism 40 is located on one side of deep cleaning mechanism 10 and is used to move material frame 12 between different mechanisms to achieve cleaning and drying of filter screen inside material frame 12.

[0044] The lifting mechanism 40 includes a lifting seat 42, on which a lifting screw 43 is rotatably mounted. A movable seat 13 is threadedly connected to the lifting screw 43. The lifting screw 43 rotates to drive the movable seat 13 to move up and down, thereby realizing the movement of the material frame 12. A lifting motor is provided on the top of the lifting seat 42. The output shaft of the lifting motor is fixedly connected to the end of the lifting screw 43. The lifting seat 42 is mounted on a fixed frame 41, and the loading box is mounted on one side of the fixed frame 41.

[0045] Working principle:

[0046] The filter screen is put into the material box 31. The drive motor drives the rotating shaft 36 to rotate. The drive gear 35 at the end of the rotating shaft 36 meshes with another drive gear 35, which in turn drives another rotating shaft 36 to rotate. The two rotating shafts 36 drive the two feed rollers 33 to rotate relative to each other, so that the air conditioning filter screen can pass vertically through the feed port 34 and fall into the discharge box 32 under the control of the two feed rollers 33.

[0047] As the filter screen continues to fall, the two feed rollers 33 are fixed, allowing the two brush heads 305 to brush the two sides of the filter screen. The brushed filter screen falls onto the guide slope 38 of the feed box 32 and moves to the discharge port 37 via the guide slope 38. At this point, the limit wheel 301 contacts the air conditioning filter screen and drives the air conditioning filter screen to move outward from the discharge port 37. The air conditioning filter screen is fixed while it is moving.

[0048] The blower box 21 delivers air to the rotating cover 23 of the flushing box 22, and blows the continuously falling filter screen through the air outlet 24 on the rotating cover 23 to remove loose dust and dirt generated by brushing on the filter screen, thereby reducing the interference of impurities generated by ultrasonic cleaning.

[0049] After being washed by the airflow, the filter screen falls onto the material frame 12 of the ultrasonic cleaner 11. The ultrasonic cleaner 11 uses ultrasonic cleaning to clean the filter screen in the material frame 12, removing fine particles, grease residue and stubborn micro-contaminations from the filter screen. Since a large amount of dirt has been removed from the surface of the filter screen after the previous brushing and rinsing, the ultrasonic cleaning time is greatly shortened, reducing the damage to the filter screen and improving the cleaning efficiency.

[0050] After ultrasonic cleaning is completed, the lifting mechanism 40 drives the material frame 12 to rise. When the material frame 12 moves upward, the two guide rods 14 abut against the rotating rod 25 and drive the rotating rod 25 to rotate, thereby causing the rotating cover 23 to rotate on the rinsing box 22. The air outlet 24 of the rotating cover 23 faces the material frame 12. The fan 26 delivers air into the rotating cover 23 and heats it with electric heating wire to dry the filter screen in the material frame 12. This completes the integrated operation of brushing, rinsing, ultrasonic cleaning and drying of the filter screen.
