[0018] The present application has the following advantages:

[0019] 1.

This eliminates the need to set multiple filters and can effectively utilize each area of ​​the filter plate, ensuring that the filter plate is fully utilized.

[0020] 2. By setting up a cleaning box and a hollow brush plate and liquid inlet mechanism, after the filter plate has rotated, the side of the filter plate with dust and dirt can be turned into the cleaning box. At this time, the liquid inlet mechanism can discharge the condensate generated by the air conditioning unit through the drain hole on the hollow brush plate, which can clean the side of the filter plate with dust and dirt, thereby keeping the filter plate clean and enabling it to be used continuously.

[0021] 3. By setting up a dehumidification mechanism and a compressed air tank, the dehumidification mechanism can continuously release the air in the compressed air tank, which can blow on the filter plate and quickly evaporate the water stains on the filter plate. This allows the air passing through the filter plate to be dried before entering the machine body.

[0022] 4. By setting up a push mechanism with incomplete gears and drive gears working together, the filter plate can rotate intermittently periodically. This allows each area of ​​the filter plate to remain in place for a period of time, which can effectively clean each area of ​​the filter plate. On the other hand, it also allows enough time for the filter plate to be dried by blowing air.

[0023] 5. Through the air inlet and outlet pipes, air can be continuously supplied to the compressed air tank during the intermittent rotation of the filter plate driven by the push structure. This continuous replenishment of the compressed air tank can greatly reduce the loss of air in the compressed air tank, thereby effectively extending the cycle of additional air replenishment of the compressed air tank and reducing maintenance costs.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application.

[0035] Embodiment one:

[0036] A dual-mode dehumidification air conditioning unit, comprising a body 1, the body 1 is provided with an exhaust fan 2, and the body 1 is also provided with an air inlet 7, and the body 1 is provided with an evaporator (not shown in the figure, which is an evaporating device of an existing air conditioning unit), specifically, air can enter the body 1 through the air inlet 7, and the air is cooled by the evaporator and then discharged as cold air through the exhaust fan 2, which has the same structure and principle as the existing air conditioning unit.

[0037] A cleaning box 4 is fixed to the side wall of the body 1, the cleaning box 4 is in a semicircular box shape, a filter plate 6 is rotatably arranged in the cleaning box 4, and the filter plate 6 is in a circular cake shape, the filter plate 6 is arranged outside the air inlet 7 and used for filtering air entering the body 1, the air inlet 7 is an arc-shaped through hole and is concentrically arranged with the filter plate 6, and the filter plate 6 can completely cover the air inlet 7;

[0038] The filter plate 6 is driven to rotate by a driving mechanism, a hollow brush plate 16 is fixed to the inner wall of the cleaning box 4, a plurality of drain holes 25 are formed in the side of the hollow brush plate 16 close to the filter plate 6, a liquid inlet mechanism is connected to the hollow brush plate 16, and the liquid inlet mechanism can deliver condensate water generated by the evaporator into the hollow brush plate 16.

[0039] A compressed air tank 3 is fixed outside the body 1, the compressed air tank 3 is used for storing air, and the compressed air tank 3 is connected with a dehumidification mechanism, the dehumidification mechanism is used for dehumidifying and drying the filter plate 6. The compressed air tank 3 is provided with a gas supplementing device, the gas supplementing device is used for supplementing the lost air in the compressed air tank 3 through an air compressor.

[0040] The pushing mechanism is composed of a servo motor 12, an incomplete gear 13 and a driving gear 15, wherein the servo motor 12 is fixedly installed on the outer wall of the cleaning box 4, the output shaft of the servo motor 12 is fixedly connected with the incomplete gear 13, the driving gear 15 is fixed at the position of the shaft center of the filter plate 6, and the incomplete gear 13 is matched with the driving gear 15. It should be noted that the filter plate 6 can be rotatably arranged in the cleaning box 4 through a damping shaft, so that when the incomplete gear 13 is disengaged from the driving gear 15, the filter plate 6 can keep its position unchanged by relying on the friction resistance of the damping shaft.

[0041] In the embodiment, in the "cleaning mode", after the servo motor 12 drives the incomplete gear 13 to continuously rotate, the incomplete gear 13 will periodically engage with the driving gear 15, and when the incomplete gear 13 engages with the driving gear 15, the driving gear 15 and the filter plate 6 can be driven to rotate by a certain angle.

[0042] In this way, the cleaner side of the filter plate 6 can be rotated to the position of the air inlet 7, so that the air can smoothly enter the body 1 through the air inlet 7, and at the same time, the side of the filter plate 6 containing dust can be turned to the cleaning box 4, at this time, the liquid inlet mechanism can transport the condensate water generated by the evaporator to the hollow brush plate 16, and the dirty side of the filter plate 6 entering the cleaning box 4 can be brushed by the hollow brush plate 16 to remove the dust on the dirty side of the filter plate 6, so as to maintain the good filtering performance of the filter plate 6. With the continuous intermittent rotation of the filter plate 6, the area of the filter plate 6 near the air inlet 7 can always be kept clean, and multiple filter devices do not need to be set up for replacement.

[0043] It should be noted that the condensate water after cleaning dirt will be discharged to the outside along the condensate water discharge pipeline (not shown in the figure) of the air conditioning unit.

[0044] In addition, the device also has a "drying mode", specifically, the dehumidification mechanism can release the air in the compressed air tank 3 and spray it to the cleaned filter plate 6, so that the water stains on the filter plate 6 can be quickly evaporated and cleaned, so that the air entering the air inlet 7 is clean and dry.

[0045] Embodiment two:

[0046] In the embodiment, specifically, as Figure 6As shown, the liquid inlet mechanism includes a liquid inlet pipe 11, a liquid outlet pipe 14, a liquid suction cylinder 8 and a pressure plug 19. The liquid suction cylinder 8 is fixed in the machine body 1, the pressure plug 19 is sealingly and slidably arranged in the liquid suction cylinder 8, the liquid inlet pipe 11 is connectable with a drain pipe of an evaporator for absorbing condensed water of the evaporator, the liquid inlet pipe 11 and the liquid outlet pipe 14 are both in communication with the liquid suction cylinder 8, the pressure plug 19 is driven to move by a driving mechanism, and the liquid outlet pipe 14 is in communication with the hollow brush plate 16 at an end away from the liquid suction cylinder 8.

[0047] The driving mechanism includes a push rod 17 and a driving rod 18, and the push rod 17 and the driving rod 18 are rotationally connected. The push rod 17 is rotationally arranged on a side wall of the incomplete gear 13 at an end away from the driving rod 18, and the driving rod 18 is fixedly connected with the pressure plug 19 at an end away from the push rod 17. A one-way valve is arranged in each of the liquid inlet pipe 11 and the liquid outlet pipe 14. Specifically, the one-way valve in the liquid inlet pipe 11 restricts the condensed water to flow from the liquid inlet pipe 11 into the liquid suction cylinder 8 in one direction, and the one-way valve in the liquid outlet pipe 14 restricts the condensed water to flow from the liquid suction cylinder 8 to the hollow brush plate 16 in one direction.

[0048] The connection between the push rod 17 and the incomplete gear 13 is arranged at an eccentric position of the incomplete gear 13.

[0049] With reference to Figure 3 , the dehumidifying mechanism includes an exhaust pipe 5, a hollow air plate 22 and a baffle 21. The baffle 21 is sealingly and slidably arranged in the hollow air plate 22. With reference to Figure 8 , a plurality of exhaust holes 24 are formed on a side of the hollow air plate 22 close to the filter plate 6, a plurality of through holes 23 are formed on a side wall of the baffle 21, one end of the exhaust pipe 5 is in communication with the compressed air tank 3, and the other end of the exhaust pipe 5 is in communication with the inside of the hollow air plate 22. Specifically, when the baffle 21 reciprocates along the hollow air plate 22, the through holes 23 on the baffle 21 will be continuously communicated with or separated from the exhaust holes 24. Whenever the through holes 23 are communicated with the exhaust holes 24, the air input into the hollow air plate 22 can be blown to the filter plate 6 through the through holes 23 and the exhaust holes 24, and when the through holes 23 are separated from the exhaust holes 24, the air cannot be temporarily input into the hollow air plate 22 through the compressed air tank 3. In this way, the air can be blown to the filter plate 6 for drying and dehumidifying in cooperation with the intermittent rotation of the filter plate 6, and the loss of air in the compressed air tank 3 can be reduced, thereby prolonging the air supply period of the compressed air tank 3.

[0050] With reference to Figure 6 , a connecting rod 20 is fixedly connected on a side wall of the driving rod 18, and an end of the connecting rod 20 away from the driving rod 18 is fixedly connected with the baffle 21.

[0051] With reference to Figure 4 , Figure 5 and Figure 6In this embodiment, when the incomplete gear 13 rotates continuously, it will drive the push rod 17 to rotate around its axis, and the push rod 17 is connected with the rotation of the incomplete gear 13, which will constantly push the drive rod 18 to move up and down reciprocatingly, and the drive rod 18 can push the plug 19 to move up and down in the suction cylinder 8. Referring to Figure 6 When the plug 19 moves up, a negative pressure can be generated on the lower side of the plug 19, which can suck the condensed water generated by the evaporator into the suction cylinder 8 through the liquid inlet pipe 11, and when the plug 19 moves down, the condensed water sucked can be squeezed into the hollow brush plate 16 through the liquid outlet pipe 14, and finally discharged from the drain hole 25 on the side wall of the hollow brush plate 16. Thus, when the dirty surface of the filter plate 6 is turned into the cleaning box 4 as described in Embodiment One, it can be brushed to keep the filter plate 6 clean.

[0052] Further, referring to Figure 1 、 Figure 3 、 Figure 5 、 Figure 7 and Figure 8 , the air in the compressed air tank 3 can be input into the hollow air plate 22 through the exhaust pipe 5, and with the continuous up and down movement of the drive rod 18, the baffle 21 will also be driven to move up and down in the hollow air plate 22 through the connecting rod 20. During the up and down movement of the baffle 21 in the hollow air plate 22, the through hole 23 on the baffle 21 will constantly be opposite to the exhaust hole 24 on the side wall of the hollow air plate 22, and when the through hole 23 is opposite to the exhaust hole 24, the air input into the hollow air plate 22 can be discharged through the through hole 23 and the exhaust hole 24 and blown to the part of the filter plate 6 after brushing, so that the water stains on the filter plate 6 can be quickly evaporated and dried, and the air entering the air inlet 7 through the filter plate 6 can be clean and dry.

[0053] It is worth mentioning that, in combination with the contents in Embodiment One, by setting the push mechanism of the incomplete gear 13 and the drive gear 15 cooperating with each other, the filter plate 6 can be periodically and intermittently rotated, which can not only effectively clean each area of the filter plate 6, but also have enough time to dry the filter plate 6.

[0054] Embodiment Three:

[0055] Referring to Figure 3 and Figure 6, and the out-gas pipe 10 is communicated with the compressed gas tank 3 at the end far from the liquid suction cylinder 8. The in-gas pipe 9 and the out-gas pipe 10 are arranged at the upper end of the liquid suction cylinder 8, and the in-liquid pipe 11 and the out-liquid pipe 14 are arranged at the lower end of the liquid suction cylinder 8, and one-way valves are arranged in the in-gas pipe 9 and the out-gas pipe 10. It should be noted that the one-way valve in the in-gas pipe 9 limits the air to flow into the liquid suction cylinder 8 from the in-gas pipe 9 in one direction, and the one-way valve in the out-gas pipe 10 limits the air to flow from the liquid suction cylinder 8 to the compressed gas tank 3 in one direction, and at the same time, it can prevent the air in the compressed gas tank 3 from flowing back through the out-gas pipe 10.

[0056] As described in Embodiment 2, when the plug 19 in the liquid suction cylinder 8 moves up and down, the negative pressure will be generated at the upper side of the plug 19 when it moves down, so that the air can be sucked into the upper side of the liquid suction cylinder 8 through the in-gas pipe 9, and when the plug 19 moves up, the air above the plug 19 can be blown into the compressed gas tank 3 through the out-gas pipe 10 to supplement the part of the air lost from the compressed gas tank 3, so that part of the air can be blown into the compressed gas tank 3 during the operation of the device, so that the air in the compressed gas tank 3 can be used for a longer time before it needs to be supplemented, thereby prolonging the air supplement period and reducing the maintenance cost.

[0057] The above is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
