Description

Technical Field

[0001] This utility model belongs to the technical field of cold storage refrigeration equipment, and in particular, it relates to a defrosting mechanism for cold storage refrigeration equipment. Background Technology

[0002] During the operation of refrigeration equipment in cold storage, frost will continuously form on the surface of the evaporator. The presence of frost increases thermal resistance, reduces the heat transfer efficiency of the evaporator, leading to a decrease in cooling effect and increased energy consumption. If the frost layer is too thick, it may also block the air ducts of the evaporator, affecting air circulation and further impacting the normal operation of the refrigeration equipment. Common defrosting methods include hot gas defrosting and electric defrosting, but the defrosting mechanism has weak self-adaptive contact ability with the frost surface and cannot adapt well to the frost surface, thus failing to fully cover and contact the frost layer. As a result, some frost cannot be melted in time, affecting the refrigeration efficiency of the cold storage and increasing energy consumption.

[0003] A search revealed a Chinese patent document (authorization announcement number CN222544184U), which discloses a defrosting mechanism for cold storage refrigeration equipment. The mechanism includes a defrost storage box, two sets of supporting vertical plates fixedly connected to the box, a movable plate slidably installed between the two sets of supporting vertical plates, an mounting plate fixedly connected to one side of the movable plate, a scraper fixedly connected to one side of the mounting plate, and defrosting platforms fixedly installed on the two sets of supporting vertical plates. The defrosting platform has four sets of sliding grooves inside, each containing a slider. A defrosting roller is positioned between two sets of opposing sliders. A reciprocating screw is rotatably installed on the defrost storage box, threadedly connected to the movable plate. A connecting rod is movably installed between the slider and the movable plate. In this invention, a reciprocating screw, along with a scraper, a moving plate, a slider, a rotating rod, gears, and a rack, removes frost from the top of the cold storage unit using a defrosting roller. The scraper removes frost from the side walls of the cold storage unit, improving the defrosting efficiency. This mechanism can meet basic defrosting needs. However, the defrosting mechanism has weak self-adaptive contact with the frost body and cannot adapt well to the frost surface, thus failing to fully cover and contact the frost layer. This results in some frost layers not being melted in time, affecting the refrigeration efficiency of the cold storage unit and increasing energy consumption. Utility Model Content

[0004] The purpose of this utility model is to provide a defrosting mechanism for cold storage refrigeration equipment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a defrosting mechanism for cold storage refrigeration equipment, including a base for support, two hollow columns for adjustment on the top of the base, and a defrosting box installed at the bottom of the two hollow columns;

[0006] Both hollow columns have guide grooves for movement inside, and sliding grooves on both sides of the guide grooves. A compression spring is connected inside the hollow column, and a moving disk is connected to one end of the compression spring. The moving disk is slidably disposed inside the guide groove. A contact point is installed inside the hollow column, and a contact rod for cooperating with the contact point is installed on the side of the moving disk. A motor is installed on the outer periphery of the moving disk, and the output shaft of the motor is connected to a rotating shaft through a coupling. A defrosting wheel for defrosting the cold storage refrigeration equipment is installed at the end of the rotating shaft.

[0007] Preferably, an air intake box is installed on the side of the hollow column, and air inlets for ventilation are provided on both sides of the air intake box, with a fan installed inside the air inlet.

[0009] Preferably, the top of the base is equipped with a lifting platform for height adjustment, the movable part of the lifting platform is connected to a bracket, and a buffer frame is welded to the top of the bracket.

[0010] Preferably, a buffer spring is connected to the side of the buffer frame, a movable plate is connected to one end of the buffer spring, a connecting frame is installed on the side of the movable plate, a connecting tube for support is installed inside the connecting frame, and a connecting plate and a fixing plate are installed on the outer periphery of the connecting tube.

[0012] Preferably, the base is equipped with a plurality of casters for movement at its bottom, and a handle is installed on the side of the base.

[0013] Compared with the prior art, the technical effects and advantages of this utility model are as follows:

[0014] This defrosting mechanism for cold storage refrigeration equipment benefits from the structure of a hollow column and defrosting wheel. The frost-covered area compresses the defrosting wheel, which in turn drives the rotating shaft and moving disc to compress the spring. The moving disc then drives the contact rod to contact the contact point. When the contact point and contact rod make contact, an electrical signal is emitted to alert the operator and prevent excessive pressure from damaging the defrosting wheel and the cold storage refrigeration equipment. Compared to traditional defrosting mechanisms in cold storage refrigeration equipment, which have weaker adaptive contact capabilities, this structure improves the contact capability between the defrosting wheel and the frost, adapting well to the frost surface, adaptively covering and contacting the frost layer. The frost layer can be melted in time, improving the refrigeration efficiency of the cold storage and reducing energy consumption.

[0015] The defrosting mechanism of this cold storage refrigeration equipment benefits from the structure of the air inlet box. External gas enters the air inlet box through the air inlet, and the heating rod heats the gas. The heated gas is discharged from the exhaust port and comes into contact with the defrosting wheel, raising the surface temperature of the defrosting wheel and preventing frost from forming on the defrosting wheel due to the low temperature during the defrosting process, thus reducing the defrosting efficiency.

The moving disk 306 is slidably disposed inside the guide groove 301. A contact point 304 is installed inside the hollow column 3. A contact rod 305 for cooperating with the contact point 304 is installed on the side of the moving disk 306. The frosting area presses against the defrosting wheel 309. The defrosting wheel 309 drives the rotating shaft 308 and the moving disk 306 to press against the compression spring 303. The moving disk 306 then drives the contact rod 305 to... When contact 304 contacts and contact rod 305, an electrical signal is emitted to remind the operator and prevent excessive pressure from damaging the defrosting wheel 309 and the cold storage refrigeration equipment. A motor 307 is installed on the outer periphery of the moving plate 306. The output shaft of the motor 307 is connected to a rotating shaft 308 through a coupling. The end of the rotating shaft 308 is equipped with a defrosting wheel 309 for defrosting the cold storage refrigeration equipment. When the motor 307 is turned on, the motor 307 drives the rotating shaft 308 and the defrosting wheel 309 to rotate, increasing the contact between the defrosting wheel 309 and the defrosting part and improving the defrosting capacity. The water and frost generated during defrosting enter the defrosting box 5 for collection.

[0028] An air inlet box 4 is installed on the side of the hollow column 3. Air inlets 403 for ventilation are provided on both sides of the air inlet box 4. A fan 404 is installed inside the air inlet 403. An exhaust port 402 for exhaust is provided on the side of the air inlet box 4. An air inlet guide plate 401 is welded to the side of the air inlet box 4. Multiple heating rods 405 for heating gas are installed inside the air inlet box 4. When the fan 404 is turned on, external gas enters the air inlet box 4 through the air inlet 403. The heating rods 405 heat the gas. The heated gas is discharged from the exhaust port 402 and comes into contact with the defrosting wheel 309, raising the surface temperature of the defrosting wheel 309 and preventing the defrosting wheel 309 from frosting due to low temperature during the defrosting process, thereby reducing the defrosting efficiency.

[0029] The top of the base 1 is equipped with a lifting platform 102 for height adjustment. The movable part of the lifting platform 102 is connected to a bracket 103. A buffer frame 104 is welded to the top of the bracket 103. A buffer spring 106 is connected to the side of the buffer frame 104. One end of the buffer spring 106 is connected to a moving plate 107. A connecting frame 108 is installed on the side of the moving plate 107. A connecting pipe 109 for support is installed inside the connecting frame 108. A connecting plate 2 and a fixing plate 202 are installed on the outer periphery of the connecting pipe 109.

[0030] The side of the connecting plate 2 is welded with an arc-shaped baffle 201 to prevent defrosting water from splashing out. The connecting part of the connecting frame 108 completely penetrates the surface of the buffer frame 104. The bottom of the moving plate 107 is slidably installed on the top of the bracket 103. The bottom of the base 1 is equipped with multiple casters 101 for movement. The side of the base 1 is equipped with a handle 105. The base 1 is moved to the defrosting area by using the casters 101 and the handle 105. The lifting platform 102 drives the bracket 103 to move to the specified height. The defrosting wheel 309 contacts the frosted part of the cold storage refrigeration equipment.

[0031] Working principle

[0032] The defrosting mechanism of this cold storage refrigeration equipment works by first using the casters 101 and handle 105 to move the base 1 to the desired defrosting area. The lifting platform 102 then moves the support 103 to the designated height, bringing the defrosting wheel 309 into contact with the frosted area of ​​the cold storage refrigeration equipment. The frosted area compresses the defrosting wheel 309, which in turn drives the rotating shaft 308 and the moving disc 306 to compress the spring 303. The moving disc 306 then moves the contact rod 305 to contact the contact point 304. When the contact point 304 and the contact rod 305 contact, an electrical signal is emitted to alert the operator and prevent excessive pressure that could damage the defrosting wheel 309. In the cold storage refrigeration equipment, the fan 404 is turned on, and external gas enters the air inlet box 4 through the air inlet 403. The heating rod 405 heats the gas, and the heated gas is discharged from the exhaust port 402 and comes into contact with the defrosting wheel 309, raising the surface temperature of the defrosting wheel 309 and preventing frost from forming on the defrosting wheel 309 due to low temperature during the defrosting process, thus reducing defrosting efficiency. The motor 307 is turned on, and the motor 307 drives the rotating shaft 308 and the defrosting wheel 309 to rotate, increasing the contact between the defrosting wheel 309 and the defrosting part and improving the defrosting capacity. The water and frost generated during defrosting enter the defrosting box 5 for collection.
