Description

Technical Field

[0001] This invention relates to the field of air conditioning unit technology, and in particular to a dual-mode dehumidification air conditioning unit. Background Art

[0002] In an all-air system, the air delivered to each area must first undergo centralized processing in a machine room, and the equipment responsible for this processing is the air conditioning unit. Its core function is to regulate and control various parameters such as temperature, humidity, and airflow in the indoor environment of a building or structure, thereby creating a suitable indoor environment.

[0003] Air conditioning units often require additional filters to purify the air entering the unit. After a period of use, a large amount of dust accumulates on the filters, affecting air intake efficiency. To address this, Chinese Patent Publication No. CN113531666A proposes a dehumidifying air conditioning unit for underground engineering. This patent document describes a system with a controller, a main filter, and a secondary filter. The controller periodically replaces the secondary filter in the feed hopper with one in the housing, automatically replacing the main filter. However, even with two filters and automatic replacement, significant dust accumulation still occurs over long periods, still affecting the unit's performance. Therefore, this application proposes a dual-mode dehumidifying air conditioning unit. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a dual-mode dehumidification air conditioning unit.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A dual-mode dehumidification air conditioning unit includes a body with an exhaust fan and an air inlet inside. An evaporator is installed inside the body. A cleaning box is fixed to the side wall of the body. The cleaning box has a semi-circular box-shaped structure. A filter plate is rotatably installed inside the cleaning box. The filter plate has a disc-shaped structure and is located outside the air inlet to filter the air entering the body. The air inlet is a slightly curved through hole and is concentric with the filter plate. The filter plate can completely cover the air inlet.

[0007] The filter plate is driven to rotate by a pushing mechanism. A hollow brush plate is fixed on the inner wall of the cleaning box, and multiple drainage holes are opened on the side of the hollow brush plate near the filter plate. A liquid inlet mechanism is connected to the hollow brush plate, which can transport the condensate generated by the evaporator into the hollow brush plate.

[0008] A compressed air tank is fixed to the outside of the machine body. The compressed air tank is used to store air and is connected to a dehumidification mechanism for dehumidifying and drying the filter plate.

[0009] Preferably, the pushing mechanism consists of a servo motor, an incomplete gear, and a drive gear, wherein the servo motor is fixedly installed on the outer wall of the cleaning box, the output shaft of the servo motor is fixedly connected to the incomplete gear, the drive gear is fixed at the axial position of the filter plate, and the incomplete gear cooperates with the drive gear.

[0010] Preferably, the liquid inlet mechanism includes an inlet pipe, an outlet pipe, a suction cylinder, and a pressure plug. The suction cylinder is fixed inside the machine body, and the pressure plug is slidably disposed inside the suction cylinder. The inlet pipe can be connected to the drain pipe of the evaporator for absorbing the condensate from the evaporator. Both the inlet pipe and the outlet pipe are connected to the suction cylinder. The pressure plug is driven to move by a driving mechanism. The end of the outlet pipe away from the suction cylinder is connected to a hollow brush plate.

[0011] Preferably, the dehumidification mechanism includes an exhaust pipe, an air intake plate, and a baffle. The baffle is slidably disposed inside the air intake plate. The air intake plate has multiple exhaust holes on the side near the filter plate. The side wall of the baffle has multiple through holes. One end of the exhaust pipe is connected to a compressed air tank, and the other end of the exhaust pipe is connected to the interior of the air intake plate.

[0012] Preferably, the suction cylinder is also connected to an air inlet pipe and an air outlet pipe, and the end of the air outlet pipe away from the suction cylinder is connected to a compressed air tank.

[0013] Preferably, the air inlet pipe and air outlet pipe are located at the upper end of the liquid suction cylinder, and the liquid inlet pipe and liquid outlet pipe are located at the lower end of the liquid suction cylinder, and each of the air inlet pipe, air outlet pipe, liquid inlet pipe and liquid outlet pipe is equipped with a one-way valve.

[0014] Preferably, the driving mechanism includes a push rod and a driving rod, and the push rod and the driving rod are rotatably connected. The end of the push rod away from the driving rod is rotatably mounted on the side wall of the incomplete gear, and the end of the driving rod away from the push rod is fixedly connected to the pressure plug.

[0015] Preferably, a connecting rod is fixedly connected to the side wall of the drive rod, and the end of the connecting rod away from the drive rod is fixedly connected to the baffle.

[0016] Preferably, the connection between the push rod and the incomplete gear is located at the eccentric position of the incomplete gear.

[0017] Preferably, the compressed air tank is equipped with an air replenishment device, which is used to replenish the lost air into the compressed air tank through an air compressor.

[0018] The present invention has the following advantages:

[0019] 1. By setting a disc-shaped filter plate and an arc-shaped air inlet, and by setting a pushing mechanism to rotate the filter plate, each area of ​​the filter plate can cover the air inlet in sequence to filter and purify the air passing through the air inlet. 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.

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0035] Example 1:

[0036] A dual-mode dehumidification air conditioning unit includes a body 1, an exhaust fan 2 on the body 1, an air inlet 7 inside the body 1, and an evaporator (not shown in the figure, which is the evaporation device of an existing air conditioning unit) installed inside the body 1. Specifically, air can enter the body 1 through the air inlet 7, absorb heat and cool down by the evaporator, and then be discharged as cold air through the exhaust fan 2, which is the same as the structure and principle of existing air conditioning units.

[0037] A cleaning box 4 is fixedly installed on the side wall of the body 1. The cleaning box 4 is a semi-circular box structure. A filter plate 6 is rotatably installed inside the cleaning box 4. The filter plate 6 is a disc-shaped structure. The filter plate 6 is set outside the air inlet 7 to filter the air entering the body 1. The air inlet 7 is a slightly curved through hole and is concentric with the filter plate 6. The filter plate 6 can completely cover the air inlet 7.

[0038] The filter plate 6 is driven to rotate by the pushing mechanism. A hollow brush plate 16 is fixed on the inner wall of the cleaning box 4. Multiple drainage holes 25 are opened on the side of the hollow brush plate 16 near the filter plate 6. A liquid inlet mechanism is connected to the hollow brush plate 16. The liquid inlet mechanism can transport the condensate generated by the evaporator into the hollow brush plate 16.

[0039] A compressed air tank 3 is fixed to the outside of the main body 1. The compressed air tank 3 is used to store air and is connected to a dehumidification mechanism for dehumidifying and drying the filter plate 6. The compressed air tank 3 is equipped with an air replenishment device, which is used to replenish the lost air into the compressed air tank 3 through an air compressor.

[0040] The driving mechanism consists of a servo motor 12, an incomplete gear 13, and a drive gear 15. The servo motor 12 is fixedly mounted on the outer wall of the cleaning box 4, and its output shaft is fixedly connected to the incomplete gear 13. The drive gear 15 is fixed at the axial position of the filter plate 6, and the incomplete gear 13 meshes with the drive gear 15. It should be noted that the filter plate 6 can be rotatably mounted inside the cleaning box 4 via a damping shaft. Thus, when the incomplete gear 13 disengages from the drive gear 15, the filter plate 6 can maintain its position by relying on the frictional resistance of the damping shaft.

[0041] In this embodiment, in the "cleaning mode", after the servo motor 12 drives the incomplete gear 13 to rotate continuously, the incomplete gear 13 will periodically mesh with the drive gear 15. When the incomplete gear 13 meshes with the drive gear 15, it can drive the drive gear 15 and the filter plate 6 to rotate at a certain angle.

[0042] This allows the cleaner side of the filter plate 6 to be rotated to the air inlet 7, enabling air to smoothly enter the machine body 1 through the air inlet 7. At the same time, the dusty and dirty side of the filter plate 6 is rotated into the cleaning box 4. At this time, the liquid inlet mechanism can deliver the condensate produced by the evaporator to the hollow brush plate 16, and the hollow brush plate 16 brushes the dirty surface of the filter plate 6 that enters the cleaning box 4 to remove the dust from the dirty surface of the filter plate 6 and maintain the good filtration 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 there is no need to set up multiple filter devices for replacement.

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

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

[0045] Example 2:

[0046] In this implementation, specifically, such as Figure 6As shown, the liquid inlet mechanism includes an inlet pipe 11, an outlet pipe 14, a suction cylinder 8, and a pressure plug 19. The suction cylinder 8 is fixed inside the body 1, and the pressure plug 19 is slidably disposed inside the suction cylinder 8. The inlet pipe 11 can be connected to the drain pipe of the evaporator to absorb the condensate from the evaporator. Both the inlet pipe 11 and the outlet pipe 14 are connected to the suction cylinder 8. The pressure plug 19 is driven to move by a drive mechanism. The end of the outlet pipe 14 away from the suction cylinder 8 is connected to the hollow brush plate 16.

[0047] The drive mechanism includes a push rod 17 and a drive rod 18, which are rotatably connected. The end of the push rod 17 away from the drive rod 18 is rotatably mounted on the side wall of the incomplete gear 13, and the end of the drive rod 18 away from the push rod 17 is fixedly connected to the pressure plug 19. One-way valves are installed in both the inlet pipe 11 and the outlet pipe 14. Specifically, the one-way valve in the inlet pipe 11 restricts the condensate from flowing unidirectionally from the inlet pipe 11 into the suction cylinder 8, while the one-way valve in the outlet pipe 14 restricts the condensate from flowing unidirectionally from the suction cylinder 8 to the hollow brush plate 16.

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

[0049] Reference Figure 3 The dehumidification mechanism includes an exhaust pipe 5, an air intake plate 22, and a baffle 21. The baffle 21 is slidably and sealingly disposed within the air intake plate 22. (Refer to...) Figure 8 The air intake plate 22 has multiple exhaust holes 24 on the side near the filter plate 6, and the side wall of the baffle 21 has multiple through holes 23. One end of the exhaust pipe 5 is connected to the compressed air tank 3, and the other end of the exhaust pipe 5 is connected to the interior of the air intake plate 22. Specifically, when the baffle 21 moves back and forth along the direction of the air intake plate 22, the through holes 23 on the baffle 21 will continuously connect and disconnect with the exhaust holes 24. Whenever the through holes 23 connect with the exhaust holes 24, the air entering the air intake plate 22 can be blown to the filter plate 6 through the through holes 23 and the exhaust holes 24. When the through holes 23 disconnect from the exhaust holes 24, the air cannot be temporarily input into the air intake plate 22 through the compressed air tank 3. This setting can not only cooperate with the intermittent rotation of the filter plate 6 to facilitate the blowing of air to dry and dehumidify the filter plate 6, but also reduce the loss of air in the compressed air tank 3, thereby extending the air replenishment cycle of the compressed air tank 3.

[0050] Reference Figure 6 A connecting rod 20 is fixedly connected to the side wall of the drive rod 18, and the end of the connecting rod 20 away from the drive rod 18 is fixedly connected to the baffle 21.

[0051] Reference 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. The push rod 17 is rotatably connected to the incomplete gear 13, which will continuously push the drive rod 18 to move up and down reciprocally. Thus, the drive rod 18 can push the pressure plug 19 to move up and down inside the suction cylinder 8. (Refer to...) Figure 6 When the pressure plug 19 moves upward, a negative pressure is generated on its lower side, which can draw the condensate generated by the evaporator into the suction cylinder 8 through the liquid inlet pipe 11. When the pressure plug 19 moves downward, the drawn condensate 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. In this way, when the filter plate 6 is transferred to the cleaning box 4 with dirty surface as described in Embodiment 1, it can be brushed to keep the filter plate 6 clean.

[0052] Furthermore, refer to Figure 1 , Figure 3 , Figure 5 , Figure 7 and Figure 8 Air from the compressed air tank 3 can be input into the air intake plate 22 through the exhaust pipe 5. As the drive rod 18 moves up and down continuously, it will also drive the baffle 21 to move up and down synchronously within the air intake plate 22 through the connecting rod 20. During the up and down movement of the baffle 21 within the air intake plate 22, the through hole 23 on the baffle 21 will continuously be opposite to the exhaust hole 24 on the side wall of the air intake plate 22. Whenever the through hole 23 and the exhaust hole 24 are connected, the air input into the air intake plate 22 can be discharged through the through hole 23 and the exhaust hole 24 and blown towards the washed filter plate 6 so that the water stains on the filter plate 6 can be quickly evaporated and the air entering the air inlet 7 through the filter plate 6 can be clean and dry.

[0053] It is also worth mentioning that, in conjunction with the content of Embodiment 1, by setting a push mechanism in which the incomplete gear 13 and the drive gear 15 cooperate with each other, the filter plate 6 can be periodically and intermittently rotated. On the one hand, this allows each area of ​​the filter plate 6 to remain for a period of time, which can effectively clean each area of ​​the filter plate 6. On the other hand, it also allows enough time for the filter plate 6 to be dried by blowing air.

[0054] Example 3:

[0055] Reference Figure 3 and Figure 6The suction cylinder 8 is also connected to an air inlet pipe 9 and an air outlet pipe 10, with the end of the air outlet pipe 10 furthest from the suction cylinder 8 connected to the compressed air tank 3. The air inlet pipe 9 and air outlet pipe 10 are located at the upper end of the suction cylinder 8, while the liquid inlet pipe 11 and liquid outlet pipe 14 are located at the lower end of the suction cylinder 8. Both the air inlet pipe 9 and air outlet pipe 10 are equipped with one-way valves. It should be noted that the one-way valve in the air inlet pipe 9 restricts air from flowing unidirectionally into the suction cylinder 8, while the one-way valve in the air outlet pipe 10 restricts air from flowing unidirectionally from the suction cylinder 8 into the compressed air tank 3, and also prevents air in the compressed air tank 3 from flowing back out through the air outlet pipe 10.

[0056] As described in Embodiment 2, when the pressure plug 19 inside the liquid suction cylinder 8 moves up and down, a negative pressure will be generated on its upper side when the pressure plug 19 moves down. This allows air to be drawn into the upper side of the liquid suction cylinder 8 through the air inlet pipe 9. When the pressure plug 19 moves up, the air above the pressure plug 19 can be blown into the compressed air tank 3 through the air outlet pipe 10 to replenish the air lost from the compressed air tank 3. In this way, during the operation of this device, some air can be continuously blown into the compressed air tank 3, so that the air in the compressed air tank 3 can be used for a longer period of time before needing to be replenished, thereby extending the replenishment cycle and reducing maintenance costs.

[0057] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
