Description

Technical Field

[0001] The present invention belongs to the technical field of air conditioners, and particularly relates to a refrigeration air conditioner and an output filter thereof. Background Art

[0002] An air handling unit is a centralized air handling system. The basic centralized system is a all-air single-zone system, generally including components such as a fan, a heater, a cooler, a humidifier, a dehumidifier, a sterilizer, and a filter. An air conditioning device refers to a primary return air system, and its basic working process is: the fresh air from the outside is mixed with a part of the return air in the room, and then passes through a filter to filter out harmful substances such as dust, soot, black smoke, and organic particles in the air, which is a device for adjusting the temperature, humidity, and cleanliness of the indoor air.

[0003] Filters are provided in the air handling unit to filter the air. After long-term use, it is necessary to clean the dust on the filter mesh inside the filter. During the cleaning process of the filter mesh, since there are multiple filter meshes, multiple driving structures need to be set for the filter meshes in different directions, resulting in asynchronous cleaning and poor cleaning effect. For the above technical problems, the Chinese patent with the patent publication number CN117847691B, when in use, air enters the cylinder through the cooperation of a supply air duct and an intake air duct, pushing the moving block in the cylinder to move, and cleaning the horizontally placed filter mesh with a first cleaning brush. It can be driven by the gas entering during non-working hours, and the pressure of the gas makes the moving block move, driving the cleaning brush to clean. However, when cleaning, air enters the cylinder through the cooperation of the supply air duct and the intake air duct, so the equipment needs to be shut down, making the equipment unable to be continuously used, and the shutdown of the equipment will lead to a decline in air quality and reduce the use effect of the equipment. Summary of the Invention

[0004] The purpose of the present invention is to provide a refrigeration air conditioner and an output filter thereof, aiming to solve the technical problem that the equipment cannot be continuously used due to the need to shut down for cleaning the filtering components in the prior art.

[0005] The present invention is realized as follows. An output filter includes a housing. A partition is fixedly installed inside the housing, dividing the inside of the housing into an air inlet chamber and a filtering chamber. A support plate is fixedly installed in the filtering chamber. Multiple groups of grooves are formed in the support plate at intervals. A first filter mesh is fixedly installed in the grooves. A guiding assembly for allowing air to enter the grooves is provided on the partition.

[0006] On the side of the groove away from the partition board, a plurality of shielding boxes are fixedly installed. The shielding boxes correspond to the positions of the grooves and the grooves are located inside the shielding boxes. Second filter meshes are fixedly installed on both side walls of the shielding boxes. There is a gap between the side wall where the second filter mesh is located and the end face of the shielding box. A top plate is fixedly installed in the filtering cavity. A moving sleeve driven by a servo module is slidably installed on the top plate. A second telescopic member is fixedly installed on the moving sleeve. A U-shaped first shielding plate is fixedly installed at the output end of the second telescopic member. A second shielding plate for shielding the groove is fixedly installed at the end of the first shielding plate. A hair dryer is fixedly installed on the first shielding plate. The hair dryer is communicated with a blowing air duct. The blowing air duct is provided with two air outlet ends and the two air outlet ends are connected to the two side walls of the first shielding plate. A first exhaust fan is fixedly installed on the second shielding plate. The first exhaust fan is communicated with a collecting hose. The collecting hose is connected to an external collecting device.

[0007] Further technical solution: The guiding assembly includes air inlet covers. There are multiple groups of air inlet covers which correspond to the grooves. The air inlet covers are magnetically connected to the support plate and the corresponding grooves are located inside the air inlet covers. A connecting hose is connected to the surface of the air inlet cover away from the support plate. The connecting hose is fixedly connected to the partition board and a through groove located inside the connecting hose is opened on the partition board. A cross plate for driving different air inlet covers to move is arranged on the partition board.

[0008] Further technical solution: A first telescopic member is fixedly installed on the partition board and points to the support plate. The cross plate is fixedly installed at the output end of the first telescopic member. The cross plate is provided with multiple electromagnets. The electromagnets correspond to the positions of the air inlet covers and after the electromagnets are powered on, they adsorb the air inlet covers. The air inlet covers are made of magnetic materials. The acting force of the electromagnets on the air inlet covers is greater than the magnetic attraction force between the air inlet covers and the support plate.

[0009] Further technical solution: A frame-shaped limiting plate is fixedly installed inside the air inlet cover. A substrate is slidably installed on the limiting plate through a guiding rod. When the substrate contacts the limiting plate, the air inlet cover is closed. An elastic member is fixedly installed on the substrate. One end of the elastic member away from the substrate is fixedly connected to the guiding rod. In the initial state, the substrate contacts the limiting plate.

[0010] Further technical solution: Two lifting plates are slidably installed inside the shielding box. Brushes are fixedly installed on the surfaces of the lifting plates close to the second filter meshes. The brushes contact the second filter meshes. When the first shielding plate moves downward, it drives the lifting plates to move.

[0011] Further technical solution: Two parallel cleaning shafts are rotatably installed on the surface of the shielding box away from the support plate. A synchronous belt is jointly rotatably installed on the cleaning shafts. The lifting plates are distributed on both sides of the synchronous belt and one side edge of the synchronous belt is fixedly connected to the lifting plates. One of the upper cleaning shafts extends out of the shielding box and a gear is fixedly installed at the end of the cleaning shaft outside the shielding box. The gear is used in cooperation with a rack fixedly installed on the first shielding plate.

[0012] Further technical solution: A rotating shaft is rotatably installed at one end of the shielding box close to the support plate. A closing plate for shielding the groove is fixedly installed on the rotating shaft. A rotating power member for driving the rotating shaft to rotate is fixedly installed on the first shielding plate.

[0013] Further technical solution: The upper end of the rotating shaft extends out of the shielding box and a second permanent magnet is fixedly installed at its end. The second permanent magnet is used in cooperation with the first permanent magnet fixedly installed at the end of the output shaft of the rotating power member. The surfaces of the second permanent magnet and the first permanent magnet that are close to each other have opposite magnetic poles. A friction plate is fixedly installed on the shielding box, and the friction plate is in contact with the second permanent magnet.

[0014] Further technical solution: A second exhaust fan is fixedly installed in the filtering cavity. The second exhaust fan is communicated with the shielding box through a plurality of dust suction pipes. Valves are arranged on the dust suction pipes. The second exhaust fan is communicated with a dust discharge pipe, and the dust discharge pipe is connected with an external collection device.

[0015] The present invention also provides a refrigeration air conditioner, which includes the above-mentioned output filter, and further includes an air conditioner main body. The output filter is located in the air conditioner main body. An air inlet chamber and an air outlet chamber are arranged in the air conditioner main body. The air inlet chamber is communicated with the air inlet cavity, and the filtering cavity is communicated with the air outlet chamber.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] 1. When it is necessary to clean the first filter screen and the second filter screen, the first shielding plate is moved to a set position. The shielding box is closed by the first shielding plate, and the groove is closed by the second shielding plate. Air will enter the shielding box from the outside through the second filter screen. The second filter screen is cleaned by air backwashing. Then the air will pass through the first filter screen in the reverse direction for cleaning. The dust cleaned from the second filter screen can follow the air and pass through the first filter screen in the reverse direction. The air in the groove is pumped out by the first exhaust fan, and the dust is synchronously pumped out and transported to an external collection device, so as to realize the circulation of air from the filtering cavity through the second filter screen and the first filter screen to the outside. The first filter screen and the second filter screen are cleaned by air. Moreover, the first filter screen and the second filter screen to be cleaned are separately isolated by the first shielding plate and the second shielding plate, without affecting the first filter screen and the second filter screen at other positions to continue filtering, ensuring the continuous operation of the equipment and improving the practicability of the equipment.

[0018] 2. When the first baffle moves downward, the rack contacts and meshes with the gear. After that, the rack moves downward to drive the cleaning shaft to rotate through the gear. The cleaning shaft drives the synchronous belt to rotate, and then the lifting plates on both sides move upward and downward respectively. Thus, the brushes on the lifting plates can further clean the second filter screen. When the first baffle moves to the set position, the lifting plates drive the brushes to completely sweep across the second filter screen. After the subsequent cleaning is completed, the rack moves upward to reset the lifting plates, and the cleaning effect of the second filter screen is further improved by the brushing of the brushes, ensuring the filtering effect of the second filter screen.

[0019] 3. Before cleaning, make the closing plate contact the base plate to close the groove. At this time, turn on the hair dryer to clean the second filter screen on this group of shielding boxes. At the same time, open the valve on the dust suction pipe connected to this group of shielding boxes, and extract the air in the shielding box through the second exhaust fan, so that the dust cleaned from the second filter screen is discharged through the second exhaust fan, reducing the residence time of dust in the shielding box. After a set time, the cleaning of the second filter screen is completed. At this time, the rotary power component drives the rotating shaft to rotate in the reverse direction to release the closing of the groove, and at the same time, turn off the second exhaust fan and turn on the first exhaust fan. At this time, the dust content in the air blown into the shielding box by the hair dryer is extremely low. Then the air will pass through the first filter screen in the reverse direction for cleaning, and the air carrying dust is extracted through the first exhaust fan, avoiding the air carrying dust from passing through the first filter screen again, reducing the probability of dust residue on the first filter screen, and improving the cleaning effect of the first filter screen.

Detailed implementation manners

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0032] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0033] As Figures 1 - 10 shown, an output filter provided by the present invention includes a housing 1. A partition board 2 is fixedly installed in the housing 1 and divides the interior of the housing 1 into an air inlet chamber 3 and a filter chamber 4. A support plate 9 is fixedly installed in the filter chamber 4. A plurality of groups of grooves 10 distributed at intervals are formed on the support plate 9. A first filter screen 11 is fixedly installed in the grooves 10. A guiding component 43 for allowing air to enter the grooves 10 is arranged on the partition board 2;

[0034] On the side of the groove 10 away from the partition plate 2, a plurality of shielding boxes 12 are fixedly installed. The shielding boxes 12 correspond to the positions of the grooves 10 and the grooves 10 are located inside the shielding boxes 12. Second filter meshes 13 are fixedly installed on both side walls of the shielding boxes 12. There is a gap between the side wall where the second filter meshes 13 are located and the end face of the shielding boxes 12. A top plate 14 is fixedly installed in the filtering cavity 4. A moving sleeve 15 driven by a servo module 16 is slidably installed on the top plate 14. A second telescopic member 17 is fixedly installed on the moving sleeve 15. A U-shaped first shielding plate 18 is fixedly installed at the output end of the second telescopic member 17. A second shielding plate 19 for shielding the groove 10 is fixedly installed at the end of the first shielding plate 18. A hair dryer 37 is fixedly installed on the first shielding plate 18. The hair dryer 37 is communicated with a blowing air pipe 38. The blowing air pipe 38 is provided with two air outlet ends and the two air outlet ends are connected to the two side walls of the first shielding plate 18. A first air extractor 20 is fixedly installed on the second shielding plate 19. The first air extractor 20 is communicated with a collecting hose 21. The collecting hose 21 is connected to an external collecting device.

[0035] In actual application of this embodiment, air enters the air inlet cavity 3, and then the air flows along the channel set by the guiding component 43 and enters the groove 10. Then the air will pass through the first filter mesh 11 and enter the shielding box 12, and then leave the shielding box 12 through the filtration of the second filter mesh 13. Then the filtered air leaves from the filtering cavity 4. The filtering precision of the second filter mesh 13 is greater than that of the first filter mesh 11.

[0036] When it is necessary to clean the first filter mesh 11 and the second filter mesh 13 after long-term use, the servo module 16 drives the moving sleeve 15 to move so that the first shielding plate 18 moves to a position aligned with one of the shielding boxes 12. At this time, the connection between the guiding component 43 and the groove 10 of this group of shielding boxes 12 is disconnected. The second telescopic member 17 drives the first shielding plate 18 and the second shielding plate 19 to synchronously descend to a set position. The inner side surface of the first shielding plate 18 contacts the end face of the shielding box 12, and the second shielding plate 19 contacts the surface of the support plate 9, so as to close the shielding box 12 through the first shielding plate 18 and close the groove 10 through the second shielding plate 19.

[0037] At this time, turn on the hair dryer 37 and the first exhaust fan 20. The hair dryer 37 extracts the filtered air in the filter chamber 4 and blows it out through the air duct 38. The air blown out by the air duct 38 will pass through the second filter screen 13 from the outside and enter the shielding box 12. The second filter screen 13 is cleaned by the air back blowing. Then the air will pass through the first filter screen 11 in the reverse direction for cleaning. The dust cleaned from the second filter screen 13 can follow the air and pass through the first filter screen 11 in the reverse direction. The first exhaust fan 20 extracts the air in the groove 10 and synchronously extracts the dust and conveys it to the external collection device, so as to realize the cycle of air from the filter chamber 4 passing through the second filter screen 13 and the first filter screen 11 in the reverse direction to the outside. The first filter screen 11 and the second filter screen 13 are cleaned by the air, and the first filter screen 11 and the second filter screen 13 to be cleaned are separately isolated by the first shielding plate 18 and the second shielding plate 19, without affecting the first filter screen 11 and the second filter screen 13 at other positions to continue filtering, ensuring the continuous operation of the equipment, improving the practicability of the equipment. Subsequently, by changing the position of the first shielding plate 18, the first filter screen 11 and the second filter screen 13 of other groups can be cleaned.

[0038] In an example of this embodiment, the second telescopic member 17 is a second electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change the length, and the first shielding plate 18 is driven to move up and down by the second electric telescopic rod.

[0039] As Figures 2 - 4 shown, a kind of output filter provided by the present invention, the guiding component 43 includes an air inlet hood 7. There are multiple groups of air inlet hoods 7 and they correspond to the grooves 10. The air inlet hood 7 and the support plate 9 are magnetically connected, and the corresponding grooves 10 are located inside the air inlet hood 7. A connecting hose 8 is connected to the surface of the air inlet hood 7 away from the support plate 9. The connecting hose 8 is fixedly connected to the partition plate 2, and a through groove located inside the connecting hose 8 is opened on the partition plate 2. A cross plate 6 for driving different air inlet hoods 7 to move is arranged on the partition plate 2.

[0040] Specifically, a first telescopic member 5 is fixedly installed on the partition plate 2, the first telescopic member 5 points to the support plate 9, the cross plate 6 is fixedly installed at the output end of the first telescopic member 5. The cross plate 6 is provided with multiple groups of electromagnets. The electromagnets correspond to the positions of the air inlet hoods 7, and after the electromagnets are energized, they adsorb the air inlet hoods 7. The air inlet hoods 7 are made of magnetic materials, and the acting force of the electromagnets on the air inlet hoods 7 is greater than the magnetic adsorption force between the air inlet hoods 7 and the support plate 9.

[0041] Specifically, a frame-shaped limiting plate 39 is fixedly installed inside the air inlet hood 7. A substrate 40 is slidably installed on the limiting plate 39 through a guide rod 42. When the substrate 40 contacts the limiting plate 39, the air inlet hood 7 is closed. An elastic member 41 is fixedly installed on the substrate 40, and one end of the elastic member 41 away from the substrate 40 is fixedly connected to the guide rod 42. In the initial state, the substrate 40 contacts the limiting plate 39.

[0042] In actual application of this embodiment, when in normal use, the air inlet hood 7 and the support plate 9 are fixedly connected by magnetic attraction. At this time, the guide rod 42 contacts the support plate 9 and pushes the substrate 40 away from the limit plate 39, while compressing the elastic member 41. Air can enter the groove 10 from the gap between the limit plate 39 and the substrate 40. When it is necessary to clean the first filter screen 11 and the second filter screen 13, the electromagnet corresponding to this group of grooves 10 on the cross plate 6 is energized to adsorb and fix the air inlet hood 7. Then, the first telescopic member 5 contracts to drive the air inlet hood 7 away from the support plate 9 through the cross plate 6. At this time, under the action of the elastic member 41, the substrate 40 quickly resets to close the air inlet hood 7, ensuring that the air inlet hood 7 can be closed in time when it leaves the support plate 9, avoiding unfiltered air from entering the filter chamber 4, and thus ensuring the air filtration effect. After the subsequent cleaning is completed, the first telescopic member 5 drives this group of air inlet hoods 7 to reset and contact the support plate 9.

[0043] In an example of the present invention, the first telescopic member 5 is a first electric telescopic rod. Of course, it can also be other components such as a hydraulic cylinder that can actively change in length. The air inlet hood 7 is driven to move by the first electric telescopic rod. The elastic member 41 is a spring. Of course, it can also be other elastic components such as a elastic ball. The spring applies a reset pulling force to the substrate 40.

[0044] As Figure 7 、 Figure 8 shown, a kind of output filter provided by the present invention. Two sets of lifting plates 30 are slidably installed in the shielding box 12. A brush 31 is fixedly installed on the surface of the lifting plate 30 close to the second filter screen 13. The brush 31 contacts the second filter screen 13. When the first shielding plate 18 moves downward, it drives the lifting plate 30 to move.

[0045] Specifically, two sets of parallel cleaning shafts 28 are rotatably installed on the surface of the shielding box 12 away from the support plate 9. A synchronous belt 29 is jointly rotatably installed on the cleaning shafts 28. The lifting plates 30 are distributed on both sides of the synchronous belt 29, and the lifting plates 30 are fixedly connected to a side edge of the synchronous belt 29. One of the cleaning shafts 28 located above extends out of the shielding box 12, and a gear 36 is fixedly installed at its end outside the shielding box 12. The gear 36 is used in cooperation with a rack 35 fixedly installed on the first shielding plate 18.

[0046] In practical application of this embodiment, when the first baffle 18 moves downward, the rack 35 contacts and meshes with the gear 36. Then, as the rack 35 moves downward, it drives the cleaning shaft 28 to rotate through the gear 36. The cleaning shaft 28 drives the synchronous belt 29 to rotate, and then the lifting plates 30 on both sides move upward and downward respectively. Thus, the brush 31 on the lifting plate 30 can further clean the second filter screen 13. When the first baffle 18 moves to the set position, the lifting plate 30 drives the brush 31 to completely sweep across the second filter screen 13. After the subsequent cleaning is completed, the rack 35 moves upward to reset the lifting plate 30. The cleaning effect on the second filter screen 13 is further improved by the sweeping of the brush 31, ensuring the filtering effect of the second filter screen 13.

[0047] As Figures 7 - 10 shown, an output filter provided by the present invention is provided. A rotating shaft 24 is rotatably installed at one end of the shielding box 12 close to the support plate 9. A closing plate 25 for shielding the groove 10 is fixedly installed on the rotating shaft 24. A rotating power member 22 for driving the rotating shaft 24 to rotate is fixedly installed on the first baffle 18.

[0048] Specifically, the upper end of the rotating shaft 24 extends out of the shielding box 12 and a second permanent magnet 26 is fixedly installed at its end. The second permanent magnet 26 is used in cooperation with the first permanent magnet 23 fixedly installed at the end of the output shaft of the rotating power member 22. The surfaces of the second permanent magnet 26 and the first permanent magnet 23 facing each other have opposite magnetic poles. A friction plate 27 is fixedly installed on the shielding box 12, and the friction plate 27 contacts the second permanent magnet 26.

[0049] Specifically, a second exhaust fan 32 is fixedly installed in the filtering chamber 4. The second exhaust fan 32 is communicated with the shielding box 12 through a plurality of dust suction pipes 33. A valve is provided on the dust suction pipe 33. The second exhaust fan 32 is communicated with a dust discharge pipe 34, and the dust discharge pipe 34 is connected to an external collection device.

[0050] In actual application of this embodiment, under normal conditions, there is a frictional force between the friction plate 27 and the second permanent magnet 26 to keep the rotating shaft 24 in a fixed state. When the first baffle 18 descends to a set position, the first permanent magnet 23 contacts the second permanent magnet 26. Before cleaning, the rotary power member 22 drives the first permanent magnet 23 to rotate. The first permanent magnet 23 drives the rotating shaft 24 to rotate through the second permanent magnet 26, so that the closing plate 25 contacts the support plate 9 to close the groove 10. At this time, the hair dryer 37 is turned on to clean the second filter screen 13 on this group of shielding boxes 12. At the same time, the valve on the dust suction pipe 33 connected to this group of shielding boxes 12 is opened, and the air in the shielding box 12 is pumped out through the second exhaust fan 32, so that the dust cleaned from the second filter screen 13 is discharged through the second exhaust fan 32. After a set time, the cleaning of the second filter screen 13 is completed. At this time, the rotary power member 22 drives the rotating shaft 24 to rotate in the reverse direction to release the closing of the groove 10. At the same time, the second exhaust fan 32 is turned off and the first exhaust fan 20 is turned on. At this time, the dust content in the air blown into the shielding box 12 by the hair dryer 37 is extremely low. Then the air will pass through the first filter screen 11 in the reverse direction for cleaning, and the air carrying dust is pumped out through the first exhaust fan 20, avoiding the air carrying dust from passing through the first filter screen 11 again, reducing the probability of dust residue on the first filter screen 11, and improving the cleaning effect on the first filter screen 11.

[0051] In an example of the present invention, the rotary power member 22 is a motor. Of course, it can also be other components such as a hydraulic motor that can output rotary power. The motor drives the closing plate 25 to rotate to realize the closing and opening of the groove 10.

[0052] As Figures 1 - 10 shown, a refrigeration air conditioner provided by the present invention includes the above-mentioned output filter, and also includes an air conditioner main unit. The output filter is located inside the air conditioner main unit. An air inlet chamber and an air exhaust chamber are provided inside the air conditioner main unit. The air inlet chamber communicates with the air inlet cavity 3, and the filter cavity 4 communicates with the air exhaust chamber.

[0053] In actual application of this embodiment, air enters the air inlet chamber and enters the air inlet cavity 3 from the air inlet chamber, and then enters the filter cavity 4 after being filtered by the first filter screen 11 and the second filter screen 13. The filtered air enters the air exhaust chamber from the filter cavity 4 and is sent outwards.

[0054] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0055] In addition, it should be understood that although this specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
