Description

Technical Field

[0001] The utility model relates to the technical field of defrosting equipment, in particular to a defrosting machine for cold storage. Background Art

[0002] A defrost machine is a defrost device used in cold storage for refrigeration equipment such as air coolers. It uses a jet of high-pressure water or steam to quickly remove frost and ice from the air cooler's evaporator, maintaining efficient operation. Regular defrosting prevents frost accumulation and reduces the air cooler's cooling efficiency, extending equipment life and ensuring stable internal temperatures. It is a crucial auxiliary device in cold chain logistics and food storage.

[0003] In the prior art, for example, a Chinese patent application titled "Defrosting and Drainage Device for Air Coolers" with publication number CN219141223U discloses a technical solution comprising a hot water tank and an air cooler body. The body has a water inlet at the top and a drain pipe at the bottom. Hot water is sprayed onto the evaporator via a heating pipe, a water pump, a water delivery pipe, a water squeeze chamber, and a water inlet pipe to defrost the evaporator. The defrosted water is then drained through the drain pipe. Compared to related technical fields and similar solutions, existing devices often have a drain port at the bottom of the air cooler. Since the lower end of the air cooler is flat, some defrosted water may remain on the lower end and freeze, further hindering the drainage of the defrosted water. Utility Model Content

[0004] The utility model provides a defrosting machine for a cold storage to solve the above problems.

[0005] The utility model adopts the following technical scheme: a defrosting machine for a cold storage, comprising a defrosting mechanism and an auxiliary mechanism; the defrosting mechanism comprises a water storage tank, a water outlet pipe is fixedly installed at the rear end of the water storage tank, the water outlet pipe is L-shaped, a water pump is fixedly installed at the upper end of the water outlet pipe, a water delivery pipe is fixedly installed at the upper end of the water pump, the water delivery pipe is L-shaped, the front end of the water delivery pipe extends to the top of the evaporator in the air cooler, a drain outlet is opened at the lower end of the air cooler, the drain outlet is funnel-shaped, a filter is fixedly installed in the drain outlet, a drain pipe is fixedly installed between the drain outlet and the upper end of the water storage tank; a hook is fixedly installed at the upper end of the air cooler; a water supply pipe is fixedly installed at the front end of the water delivery pipe, and a water supply pipe is fixedly installed at the upper end of the water cooler. The pipe is arranged horizontally, and a nozzle is fixedly installed at the lower end of the water supply pipe. There are multiple nozzles, and the nozzles are evenly arranged along the axial direction of the water supply pipe; the auxiliary mechanism is arranged in the air cooler, and the auxiliary mechanism moves horizontally on the lower end surface of the air cooler to clean the defrosted water into the drain outlet; when in use, the water pump draws water from the water storage tank, transports it to the water supply pipe, and then sprays it onto the evaporator in the air cooler through the nozzle to defrost the evaporator. The defrosted water flows to the lower end surface of the air cooler, and the auxiliary mechanism cleans the defrosted water into the drain outlet. The defrosted water is filtered through the filter in the drain outlet and then flows into the water storage tank through the drain pipe for reuse.

[0006] Furthermore, the auxiliary mechanism includes a first motor, a lead screw, a first slider, a second slider and a rotating roller. Sliding grooves are formed at the lower ends of the front and rear inner walls of the cold air blower, and the sliding grooves are horizontally arranged. The first motor is fixedly installed in the sliding groove. The first slider and the second slider are respectively slidably installed in the sliding grooves of the front and rear inner walls. A threaded hole is formed in the first slider, and the lead screw is rotatably installed in the threaded hole. One end of the lead screw is rotatably connected to the sliding groove, and the other end of the lead screw is fixedly connected to the output shaft of the first motor. A rotating roller is rotatably installed between the first slider and the second slider. A scraper is fixedly installed at the lower end of the rotating roller, and the scraper abuts against the lower end surface of the cold air blower. The scraper is elastic. The first motor drives the first slider and the second slider to slide in the sliding groove through the lead screw. The first slider and the second slider drive the scraper to horizontally move on the lower end surface of the cold air blower through the rotating roller, and sweep the water after defrosting into the drain opening.

[0007] Furthermore, the auxiliary mechanism further includes a second motor, a gear, a rack and a rotating block. The second motor is fixedly installed on the first slider. The gear is fixedly installed on the output shaft of the second motor. The rack is fixedly installed at the rear end of the rotating roller, and the gear meshes with the rack. A horizontal limiting block and a vertical limiting block are fixedly installed on the side wall of the first slider close to the rotating roller. The horizontal limiting block is arranged on one side of the rotating roller close to the drain opening, and the vertical limiting block is arranged below the rotating roller. The rotating block is fixedly installed at the rear end of the rotating roller, and the rotating block rotates between the horizontal limiting block and the vertical limiting block. When the rotating roller moves away from the drain opening, the second motor drives the rotating roller to rotate, so that the rotating block abuts against the vertical limiting block. At this time, the scraper is lifted and does not contact the lower end surface of the cold air blower. When the rotating roller moves towards the drain opening, the second motor drives the rotating roller to rotate, so that the rotating block abuts against the vertical limiting block. At this time, the scraper abuts against the lower end surface of the cold air blower, and sweeps the water after defrosting into the drain opening.

[0008] Furthermore, waterproof covers are provided outside the first motor and the second motor. The waterproof covers can prevent water from seeping into the motors and prevent water from damaging the motors.

[0009] Furthermore, a water filling port is formed at the upper end of the water storage tank, and a sealing cover is threadedly connected to the water filling port. A water level window is formed at the front end of the water storage tank. Observe the water level in the water storage tank through the water level window. When water needs to be replenished, unscrew the sealing cover and add water to the water storage tank through the water filling port.

[0010] The beneficial effects are as follows: The scraper sweeps the water after defrosting on the lower end surface of the cold air blower into the drain opening, preventing water from remaining on the lower end surface of the cold air blower, facilitating the discharge of water, and improving the reuse rate of water.
