Description

Technical Field

[0001] The utility model relates to the field of air-conditioning refrigeration, in particular to an air-conditioning refrigeration device with a filtering structure. Background Art

[0002] An air-conditioning refrigeration device mainly consists of four major components: a compressor, a condenser, an expansion valve, and an evaporator. The compressor inside compresses the low-temperature and low-pressure gas into a high-temperature and high-pressure gas. The condenser is responsible for cooling the high-temperature and high-pressure Freon discharged from the compressor into a liquid state, and usually helps with heat dissipation through a fan. The function of the expansion valve or capillary tube is to reduce the pressure of the liquid Freon so that it evaporates and absorbs heat in the evaporator, thereby reducing the indoor temperature. With the increasing demand for air-conditioning refrigeration, the types of refrigeration devices are becoming more and more diverse. As shown in an air-conditioning refrigeration device with a filtering structure (publication number CN220817955U) disclosed on the Chinese Patent Network, for this type of air-conditioning refrigeration device, the user can threadedly disassemble the external snap fastener to perform an overall disassembly and replacement of the built-in filter mesh frame, without the need to perform an overall disassembly and replacement of the built-in filtering structure of the air-conditioning refrigeration device, reducing the maintenance cost.

[0003] However, for the above-mentioned publicly patented air-conditioning refrigeration devices and those in the existing market, there are still some deficiencies: The existing method of using bolt knobs to disassemble and assemble the ventilation window filter screen of the air-conditioning refrigeration device is rather cumbersome in terms of controlling the tightening and loosening of the bolts. The staff needs to unscrew the bolts one by one in order to disassemble, replace, clean, etc. the ventilation window filter screen. Therefore, technicians in this field have provided an air-conditioning refrigeration device with a filtering structure to solve the problems raised in the above background art. Summary of the Utility Model

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-6, the present utility model provides a technical solution for an air-conditioning refrigeration device with a filtering structure: The air-conditioning refrigeration device with a filtering structure includes a refrigeration box frame 1 and a refrigeration unit 7 installed inside the box body of the refrigeration box frame 1. At the upper end of the box body of the refrigeration box frame 1, cold fans 2 opposite to the condenser in the refrigeration unit 7 are symmetrically installed. And on one side of the box body of the refrigeration box frame 1, a refrigerant inlet / outlet valve port 3 connected to the evaporator in the refrigeration unit 7 is installed. By setting the cold fans 2 opposite to the condenser in the refrigeration unit 7 on the box body of the refrigeration box frame 1, when the cold fans 2 work, the outside air is drawn into the interior of the refrigeration box frame 1 through the combination of the ventilation window 6 and the filter plate 12. On the one hand, it conducts air-cooling for the overall equipment of the refrigeration unit 7, and on the other hand, it synchronously conducts air-cooling for the condenser in the refrigeration unit 7 to improve the overall operation stability of the air-conditioning refrigeration device. At the same time, by installing the refrigerant inlet / outlet valve port 3 connected to the evaporator in the refrigeration unit 7 on one side of the box body of the refrigeration box frame 1, as the inlet and outlet of cold energy, it is connected to indoor equipment.

[0024] Knob locking mechanisms 8 for locking with the ventilation filter mechanism are symmetrically arranged at the top corners of the box body of the refrigeration box frame 1. The knob locking mechanism 8 includes a locking housing 81. In the middle of the housing of the locking housing 81, a knob 82 is installed. And inside the housing of the locking housing 81, a transmission shaft 86 is rotatably connected. At the central axis of the knob 82, a bevel gear A84 is installed. At the central axis of the transmission shaft 86, a bevel gear B85 meshing with the bevel gear A84 is installed. By rotating the knob 82, the bevel gear A84 is driven to rotate. Utilizing the meshing transmission between the bevel gear A84 and the bevel gear B85, the transmission shaft 86 is driven to rotate. As a driving source, in a knob-driven manner, the knob locking mechanism 8 is opened and closed.

[0025] On both sides of the shaft rod of the transmission shaft 86, braking lead screws 87 are symmetrically arranged. And on the outer sides of the shaft rods of the two groups of braking lead screws 87, braking sliders 88 guided by the locking housing 81 are symmetrically sleeved. At the bottom end of the platform of the braking slider 88, a locking latch 83 opposite to the locking socket 10 is provided. The threads of the two groups of opposite braking lead screws 87 are arranged symmetrically in a positive and negative direction. While the transmission shaft 86 rotates, the two groups of braking lead screws 87 on both sides of its shaft rod are driven to rotate. Utilizing the positive and negative threads arranged symmetrically in a positive and negative direction on the two groups of braking lead screws 87, the knob force is converted into a horizontal thrust to push the opposite braking sliders 88 to slide symmetrically. Then, the locking latches 83 are driven to contract symmetrically and withdrawn from the locking socket 10 to release the locked state, enabling the opening and closing of the opening / closing flip cover 4, and performing disassembly, cleaning, and replacement work on the filter plate 12 on its back panel.

[0026] On the front and back sides of the box body of the refrigeration box rack 1, ventilation filter mechanisms are installed in a pairwise symmetric form. The ventilation filter mechanism includes an opening and closing flip cover 4, and the opening and closing flip cover 4 is rotationally connected to the refrigeration box rack 1 through a hinge 5 installed at the bottom plate thereof. A ventilation window 6 is formed through the panel of the opening and closing flip cover 4, and a slot 9 is formed on one side of the plate frame of the opening and closing flip cover 4. On the back plate of the opening and closing flip cover 4, installation guide rails 11 are symmetrically arranged along the notch direction of the slot 9, and a filter plate 12 opposite to the ventilation window 6 is slidably connected to the track of the installation guide rail 11. A locking socket 10 opposite to the knob lock mechanism 8 is arranged at the top corner of the back plate of the opening and closing flip cover 4. The filter plate 12 includes a filter frame 121. Guide sliding platforms 122 that are guided by the installation guide rails 11 are symmetrically arranged at the upper and lower ends of the frame of the filter frame 121, and a filter screen 123 opposite to the ventilation window 6 is installed inside the frame of the filter frame 121. By utilizing the guiding combination of the guide sliding platforms 122 on the filter plate 12 and the installation guide rails 11, the filter plate 12 can be disassembled and assembled in a sliding and pulling manner, and the filter screen 123 inside its frame can be disassembled, replaced, and cleaned.

[0027] The working principle of the present utility model is as follows: During the daily use of the air-conditioning refrigeration equipment, based on the circulating air-cooled heat exchange of the refrigerant in the condenser of the refrigeration unit 7 by the cold air fan 2, and under the condition that the refrigeration unit 7 circulates and compresses the refrigerant for refrigeration, the refrigerant is circulated and transported to the room through the refrigerant inlet / outlet valve port 3 to achieve the refrigeration effect. When the ventilation window of the subsequent refrigeration equipment needs to be regularly cleaned due to circulating and filtering air, the knob 82 can be rotated to drive the combination of the bevel gear A 84 and the bevel gear B 85 to rotate, and then drive the transmission shaft 86 to rotate. As a driving source, the two braking lead screws 87 on both sides of its shaft are driven to rotate. By utilizing the positive and negative thread teeth symmetrically arranged on the two braking lead screws 87, the knob force is converted into a horizontal thrust to push the opposite braking sliders 88 to slide symmetrically, and then drive the locking latches 83 to contract symmetrically and withdraw from the locking socket 10 to release the locked state, so that the opening and closing flip cover 4 can be opened and closed;

[0028] Then, by utilizing the intermediate transmission of the hinge 5, the opening and closing flip cover 4 is pushed to flip and open with the hinge 5 as the axis. The opening and closing flip cover 4 is opened, and by utilizing the guiding combination of the guide sliding platforms 122 on the filter plate 12 and the installation guide rails 11, the filter plate 12 is disassembled and assembled in a sliding and pulling manner, and the filter screen 123 inside its frame is regularly disassembled, replaced, and cleaned. Moreover, by opening and closing the opening and closing flip cover 4, it is convenient to directly inspect and repair the internal equipment of the refrigeration equipment. Further, after the opening and closing flip cover 4 is closed again later, only by rotating the knob lock mechanism 8 in the reverse direction can the locked state be formed again, and the operation is simple, convenient, and efficient.

[0029] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model. The structures, devices, and operation methods not specifically described and explained in the present utility model are implemented according to the conventional means in the art without special instructions and limitations.
