Description

Technical Field

[0001] This invention relates to the field of closed-loop air refrigeration cycle devices, specifically a closed-loop air refrigeration cycle device that actively recovers cold energy. Background Technology

[0002] A refrigeration cycle consists of compression, condensation, expansion, and evaporation processes. It utilizes a limited amount of refrigerant in a closed refrigeration system, repeatedly compressing, condensing, expanding, and evaporating the refrigerant, continuously absorbing heat and vaporizing at the evaporator to achieve cooling. Refrigeration cycles include compression refrigeration cycles, absorption refrigeration cycles, adsorption refrigeration cycles, vapor jet refrigeration cycles, and semiconductor refrigeration, among others.

[0003] However, in actual use, the filter screen connected to the air inlet of the air circulation cooler is fixed with a large number of bolts. When it is necessary to clean the filter screen, a large number of bolts need to be turned back and forth, which is very inconvenient. In addition, the ventilation pipe connected to the air circulation cooler does not have a convenient limiting mechanism, which makes the connection of the pipe inconvenient, affects the installation efficiency, and is not convenient for replacement.

[0004] As disclosed in Chinese Patent CN211041542U, a closed-loop air refrigeration circulation device for actively recovering cold energy includes a circulating cooler. A dustproof mesh is fixedly fastened to the left air inlet of the circulating cooler by two symmetrically arranged fixing mechanisms. A positioning screw cylinder, covering the air outlet, is fixedly connected to the right outer wall of the circulating cooler. A connecting screw cylinder is internally threaded onto the positioning screw cylinder, and one end of the connecting screw cylinder is connected to a ventilation pipe via a rotary joint. Two limiting mechanisms for restricting the rotary joint are symmetrically fixedly connected to the upper and lower sides of the right outer wall of the circulating cooler. This invention enables quick and secure installation and removal of the dustproof mesh, facilitating cleaning and use, and making the connection between the ventilation pipe and the circulating cooler more stable.

[0005] However, in the existing technology, when a closed-loop air refrigeration cycle device is in use, water often condenses on the outer surface of the condenser tube due to the temperature difference during the refrigeration process. In the existing technology, the water is usually collected and discharged directly, resulting in a waste of cooling capacity.

[0006] Therefore, we urgently need to provide a closed-loop air refrigeration cycle device that actively recovers cold energy. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This closed-loop air refrigeration cycle device with active cold energy recovery can guide the condensate on the outer surface of the condenser tube into the cooling box through the collection box and connecting pipe by setting the cold energy recovery structure.

The cold energy of the condensate can be used to cool down the heat generated by the circulating refrigeration unit during operation.

[0021] 2. This closed-loop air refrigeration circulation device with active cold energy recovery can use an asynchronous motor to drive the lead screw to rotate through the cleaning structure.

[0022] 3. The closed-loop air refrigeration circulation device that actively recovers cold energy has a filter plate that is slidably connected to the right side of the air conditioner housing through a rectangular hole, and is also slidably connected to the dust collection box and the right side of the air conditioner housing through a rectangular hole. This facilitates the removal of the filter plate and the dust collection box, making it easy to replace the filter plate and to empty and clean the dust collection box. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0035] Please see Figures 1-8 The present invention provides a technical solution:

[0036] Example 1:

[0037] A closed-loop air refrigeration cycle device for actively recovering cold energy includes an air conditioner housing 1. A cold energy recovery structure is installed on the top of the back side inside the air conditioner housing 1. A blowing structure is provided on the front of the cold energy recovery structure. A cleaning structure is installed near the top of the front side inside the air conditioner housing 1. A filter collection structure is installed at the bottom of the cleaning structure.

[0038] The cold energy recovery structure includes a circulating chiller 101, a condenser pipe 102 mounted on the front of the circulating chiller 101, a collection box 103 at the bottom of the condenser pipe 102, a connecting pipe 104 mounted in the middle of the bottom surface of the collection box 103, a cooling box 105 connected to the end of the connecting pipe 104 away from the collection box 103, a sponge 106 installed inside the cooling box 105, and a guide pipe 107 mounted in the middle of the bottom surface of the cooling box 105. The back of the circulating chiller 101 is fixedly connected to the back of the air conditioner housing 1 near the top, the top surface of the cooling box 105 is fixedly connected to the bottom surface of the circulating chiller 101, and the bottom end of the outer surface of the guide pipe 107 is fixedly connected to the inner wall of a round hole in the middle of the back of the air conditioner housing 1 near the bottom.

[0039] The air blowing structure includes a fixed rod 201, with a fixed bracket 202 fixedly connected to one end of the front of the fixed rod 201. A fan 203 is installed inside the fixed bracket 202, and louvers 204 are provided on the front of the fan 203. A connecting shaft 205 is fixedly connected to the top and bottom of the louvers 204. One end of the back of the fixed rod 201 is fixedly connected to the front of the circulating refrigeration unit 101. The outer surface of the connecting shaft 205 is rotatably connected to the inner wall of the rectangular through hole on the front of the air conditioner casing 1, with the top and bottom surfaces having circular grooves.

[0040] By setting up a cold energy recovery structure, the condensate on the outer surface of the condenser tube 102 can be guided into the cooling box 105 through the collection box 103 and the connecting pipe 104. The sponge 106 inside the cooling box 105 absorbs the condensate and retains it for a certain period of time. The cold energy of the condensate can be used to cool down the heat generated by the circulating chiller 101 during operation.

[0041] During the operation of the circulating chiller 101, water droplets condense on the outer surface of the condenser tube 102 due to temperature differences. These small droplets fall into the collection box 103 due to gravity and flow into the cooling box 105 via the connecting pipe 104. Because the cooling box 105 contains a sponge 106, the condensate can be retained for a certain period. Utilizing the low temperature of the condensate and the fact that the cooling box 105 is in contact with the bottom of the circulating chiller 101, the heat generated during operation can be cooled. The low temperature generated by the condenser tube 102 can be dissipated by turning on the fan 203, blowing cool air through the rectangular opening on the front of the air conditioner casing 1. The direction of the airflow can be effectively adjusted by changing the angle of the louvers 204.

[0042] Example 2:

[0043] The cleaning structure includes an installation and connection unit and a cleaning unit. The cleaning unit includes an asynchronous motor 302, with a lead screw 303 connected to the output end of the asynchronous motor 302. A sleeve 306 is connected to the outer surface of the lead screw 303, and a slider 307 is fixedly installed on the outer surface of the sleeve 306. A brush plate 308 is fixedly installed on the bottom surface of the slider 307, and brush bristles 309 are installed on the front surface of the brush plate 308. The installation and connection unit includes a mounting plate 301, with a bearing 305 on the left side of the mounting plate 301, and a positioning plate 304 is installed on the outer surface of the bearing 305.

[0044] The back of the mounting plate 301 is detachably connected to the front of the asynchronous motor 302. The front of the mounting plate 301 is fixedly connected to the front of the inside of the air conditioner housing 1. The inside of the bearing 305 is fixedly connected to the left and right ends of the outer surface of the lead screw 303. The front of the positioning plate 304 is fixedly connected to the front of the inside of the air conditioner housing 1. The front of the slider 307 is slidably connected to the front of the inside of the air conditioner housing 1.

[0045] The filter collection structure includes a U-shaped guide rail 401, a filter plate 402 slidably connected inside the U-shaped guide rail 401, a push-pull plate 403 fixedly installed on the right side of the filter plate 402, a dust collection box 404 at the bottom of the U-shaped guide rail 401, a pull plate 406 fixedly connected to the right side of the dust collection box 404, and a support plate 405 slidably connected to the bottom surface of the dust collection box 404. The U-shaped guide rail 401 is fixedly connected to the front of the interior of the air conditioner housing 1, the left and right ends of the support plate 405 are fixedly connected to one side of the front of the left and right ends of the interior of the air conditioner housing 1, the outer surface of the filter plate 402 is slidably connected to the inner wall of the rectangular hole on the right side of the air conditioner housing 1, and the outer surface of the dust collection box 404 is slidably connected to the inner wall of the rectangular hole on the right side of the air conditioner housing 1.

[0046] The cleaning structure utilizes an asynchronous motor 302 to drive a lead screw 303 to rotate. The rotation of the lead screw 303 drives the sleeve 306 and slider 307 to reciprocate, thereby causing the brush plate 308 and brush bristles 309 to brush the surface of the filter plate 402, effectively cleaning the filter plate 402. The dust collection box 404 collects the dust.

[0047] The filter plate is slidably connected to the right side of the air conditioner housing 1 through a rectangular hole, and is also slidably connected to the dust collection box 404 and the right side of the air conditioner housing 1 through a rectangular hole. This facilitates the removal of the filter plate 402 and the dust collection box 404, making it easy to replace the filter plate 402 and to empty and clean the dust collection box 404.

[0048] When cleaning the filter plate 402, the asynchronous motor 302 drives the lead screw 303 to rotate. The threaded connection between the lead screw 303 and the sleeve 306 drives the slider 307 to reciprocate. During the reciprocating motion of the slider 307, the brush plate 308 and the brush bristles 309 will reciprocate. This can effectively clean the dust on the surface of the filter plate 402 and make the dust fall into the dust collection box 404. At regular intervals, the filter plate 402 and the dust collection box 404 can be removed by pulling the push-pull plate 403 and the pull plate 406 to replace or empty the dust inside the dust collection box 404.
