Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator compressors, and specifically relates to a heat dissipation structure for a refrigerator compressor compartment. Background Technique

[0002] A compressor is a driven fluid machine that raises low-pressure gas to high-pressure gas, and it is the heart of a refrigeration system. Compressors are widely used in household appliances such as refrigerators. The compressor of a refrigerator is one of the core components of the refrigerator. A compressor is a fluid machine that changes low-pressure refrigerant into high-pressure refrigerant, and a large amount of heat is released during the process of compressing the refrigerant.

[0003] For a currently used heat dissipation structure for a refrigerator compressor compartment, after retrieval, it is found that, for example, a Chinese patent document with the authorized publication number CN210154171U discloses a refrigerator compressor heat dissipation device, which includes a compressor placement compartment and a compressor body. A compressor housing is arranged outside the compressor body. The bottom end of the compressor housing is fixedly connected with a base, and screw holes are formed on the surface of the base. The base is fixed at the bottom end inside the compressor placement compartment through the screw holes. A condenser is embedded at the bottom end of the inner side wall of the compressor placement compartment. A water tank and a micro water pump are fixedly installed at the bottom end inside the compressor placement compartment. A heat dissipation liquid with a relatively large specific heat capacity is placed in the water tank. A water pipe is connected between the condenser, the water tank and the micro water pump, and the water pipe is annularly fixed on the inner wall of the annular channel. A rectangular groove is formed on the outer side surface of the compressor placement compartment at the position where the condenser is embedded, and a dust-proof ventilation cover is fixedly installed at the opening of the rectangular groove.

[0004] Although the above patent solves the problems in the above background technique, there are still the following deficiencies: 1. In the compressor, the dust-proof ventilation cover is relied on to block dust, and dust is likely to accumulate during use, and it is necessary to manually clean the dust-proof ventilation cover, and the efficiency is not good, which in turn affects the ventilation effect of the compressor and is not conducive to subsequent use; 2. At the same time, the compressor does not have the function of temperature monitoring. Therefore, during use, it is impossible to ensure that the water pump transports the liquid in time, which in turn easily causes the compressor to overheat and is not conducive to extending the service life of the compressor.

[0005] In summary, the utility model solves the problems in the above background technique by designing a heat dissipation structure for a refrigerator compressor compartment. Content of the Utility Model

[0030] For the embodiments, please refer to Figures 1-5 , the present invention provides a technical solution:

[0031] A heat dissipation structure for a refrigerator compressor compartment, including a compartment main body 1, a dust filter plate 2 is embedded and installed on the left side of the compartment main body 1, an air inlet groove 201 is formed on the left surface of the dust filter plate 2, a dust filter screen 202 is fixedly installed inside the air inlet groove 201, a cleaning mechanism 3 is arranged at the rear side of the dust filter screen 202, an installation plate 4 is embedded and installed on the rear side of the compartment main body 1, a liquid storage tank 401 and a circulation pump 402 are respectively fixedly arranged on the rear side of the installation plate 4, a control module 403, a temperature sensor 404 and a drainage pipe 405 are respectively fixedly installed on the front side of the installation plate 4, an installation compartment 5 is formed inside the compartment main body 1, and a heat dissipation fan 501 is embedded and arranged on the right inner wall of the installation compartment 5;

[0032] Specifically, the right inner wall of the air inlet groove 201 extends into the installation compartment 5;

[0033] In this implementation, the intake air slot 201 is mainly provided to facilitate the entry of air into the interior of the machine cabin main body 1, while the cooling fan 501 is mainly used to discharge the air inside the machine cabin main body 1.

[0034] Specifically, a filling port is provided on the right side of the top of the liquid storage tank 401, and the interior thereof contains a coolant. The input end of the circulation pump 402 extends into the bottom end of the liquid storage tank 401 through a pipeline. The drainage pipe 405 is arranged in a serpentine winding manner and is made of copper material. One end of the drainage pipe 405 penetrates through the front surface of the mounting plate 4 through a pipeline and is connected to the inner wall of the top end of the liquid storage tank 401, and the other end thereof penetrates through the front surface of the mounting plate 4 through a pipeline and is connected to the output end of the circulation pump 402;

[0035] In this implementation, the circulation pump 402 is mainly used to guide the coolant in the liquid storage tank 401 to gradually flow through the drainage pipe 405 and return to the liquid storage tank 401. When it flows through the interior of the machine cabin main body 1, it can adsorb heat, thereby achieving the effect of dissipating heat from the interior of the machine cabin main body 1.

[0036] It should be noted that the reciprocating motor 304, the temperature sensor 404, the circulation pump 402, and the cooling fan 501 are respectively electrically connected to the control module 403 through wires;

[0037] In this embodiment, please refer to Figure 1 、 Figure 3 and Figure 4 , the cleaning mechanism 3 includes a square slot 301, a sliding slot 302, a dust collection box 303, and a reciprocating motor 304. The square slot 301 and the sliding slot 302 are both opened on the left surface of the machine cabin main body 1. The square slot 301 is located at the front and rear ends of the left side of the machine cabin main body 1 respectively. A sliding rod 305 is arranged inside the leftmost square slot 301, and a transmission screw rod 306 is rotatably arranged inside the rightmost square slot 301. U-shaped frames 307 are sleeved on the outer surfaces of the transmission screw rod 306 and the sliding rod 305. A cleaning brush 308 is arranged inside the U-shaped frame 307. A sliding strip 309 is fixedly installed on the right side of the dust collection box 303. The reciprocating motor 304 is embedded in the top side surface of the machine cabin main body 1;

[0038] Specifically, the vertical cross-sectional shape of the sliding strip 309 matches and slides with the sliding slot 302. The rear end inner wall of the sliding slot 302 is flush with the rear side surface of the machine cabin main body 1. The front end inner wall of the U-shaped frame 307 is slidably connected to the outer surface of the sliding rod 305, and the rear end inner wall thereof is threadedly connected to the outer surface of the transmission screw rod 306. The output end of the reciprocating motor 304 penetrates through the top surface of the machine cabin main body 1 and is fixed to the top end of the transmission screw rod 306. The end of the cleaning brush 308 away from the U-shaped frame 307 contacts the dust filtering screen 202;

[0039] In this embodiment, the reciprocating motor 304 is mainly used to drive the transmission screw 306. Under the screw thread fit between the transmission screw 306 and the U-shaped frame 307 and the sliding fit between the sliding rod 305 and the U-shaped frame 307, the U-shaped frame 307 drives the cleaning brush 308 to reciprocate along the surface of the dust filter plate 2 and makes a moving contact with the dust filter screen 202, thus achieving the function of cleaning the dust on the surface of the dust filter screen 202. The dust collector 303 is provided to collect the fallen dust. Under the sliding fit between the slide bar 309 and the chute 302, it is convenient for the staff to disassemble the dust collector 303, meeting the ventilation requirement of the machine cabin main body 1.

[0040] The working process of the present utility model: When using a heat dissipation structure for a refrigerator compressor cabin, under the action of the temperature sensor 404, the temperature inside the machine cabin main body 1 can be monitored in real time. Once the value monitored by the temperature sensor 404 exceeds the threshold, the control module 403 will control the circulation pump 402 to start. Under the action of the circulation pump 402, the coolant in the liquid storage tank 401 can circulate through the drainage pipe 405 and adsorb the heat inside the machine cabin main body 1. At the same time, the cooling fan 501 is also started. Under the action of the cooling fan 501, the air outside enters the inside of the machine cabin main body 1 through the air inlet groove 201 and the dust filter screen 202, and the air inside the machine cabin main body 1 is discharged with the cooling fan 501. Thus, the heat dissipation operation inside the machine cabin main body 1 is completed, avoiding the overheating of the compressor. Further, when it is necessary to clean the dust filter screen 202, the reciprocating motor 304 is started. The output end of the reciprocating motor 304 drives the transmission screw 306 to rotate. Under the screw thread engagement between the transmission screw 306 and the U-shaped frame 307, the U-shaped frame 307 moves up and down along the outer surface of the sliding rod 305. During the movement, the cleaning brush 308 makes a moving contact with the dust filter screen 202, causing the dust on the dust filter screen 202 to fall into the dust collector 303, realizing the cleaning of the dust filter screen 202, ensuring the ventilation volume of the air inlet groove 201, and meeting the requirements of the users.

[0041] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
