Description

Technical Field

[0001] The utility model belongs to the technical field of refrigeration equipment, and in particular relates to an industrial freezer defrosting device. Background Art

[0002] The freezer used in the industrial field refers to a facility that uses various equipment for refrigeration and can be artificially controlled to maintain a stable low temperature. It can be divided into large freezers and small freezers according to individual size. When a small freezer is working, frost forms on the surface of the internal refrigeration unit, which hinders the normal operation of the refrigeration unit. When the thickness of the frost layer on the surface of the refrigeration unit reaches a certain level, the refrigeration efficiency may even drop significantly, resulting in a large waste of electricity and shortening the service life of the refrigeration system. Therefore, it is necessary to defrost the freezer within an appropriate period.

[0003] The Chinese patent application number CN202322275713.6 discloses an automatic defrosting device for a frozen storage, including a conveyor belt, which also includes a guide rail, which is arranged below the conveyor belt in a manner parallel to the conveying direction of the conveyor belt; a slider, which is slidably connected to the guide rail; a heater, which is fixed on the upper surface of the slider, and the exhaust port of the heater is tilted upward; a spring, which is arranged in a manner parallel to the guide rail, one end of the spring is fixedly connected to the slider, and the other end is fixedly connected to the guide rail. One end of the steel cable is fixedly connected to the slider; an air outlet sleeve, which is sleeved on the exhaust port of the heater, and the air outlet sleeve is provided with a sleeve portion, a duckbill portion, and a water retaining eaves located on the duckbill portion, and the duckbill portion is flat.

[0004] As the applicant conducted further research, it was found that because the defrosting device of the technical solution is fixed when defrosting the refrigeration unit of the freezer, it is unable to operate on the blind corners of the surface of the air cooler, resulting in uneven defrosting of the refrigeration unit, which may affect the normal operation of the freezer. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] An industrial freezer defrosting device, comprising:

[0007] The refrigeration unit is placed in the freezer body;

[0008] The fan assembly is placed in the freezer body and connected to the freezer body, and a heating unit is arranged in the fan assembly;

[0009] A driving assembly is connected to the freezer body and is used to drive the fan assembly to slide on the inner wall of the freezer body. The driving assembly includes a motor and a screw mechanism. The screw mechanism is connected to the output end of the motor. The outer periphery of the screw mechanism is rotatably connected to a slider. The slider is movably connected to a first connecting rod. The side of the fan assembly is connected to a second connecting rod, and the second connecting rod is hinged to the first connecting rod.

[0010] Among them, after the screw mechanism is driven by the motor, the slider moves in the setting direction of the screw mechanism, driving the fan assembly to move horizontally or vertically on the inner wall of the freezer body, and guiding the air heated by the heating unit to the refrigeration unit.

[0011] Furthermore, a guide bar is provided on the inner wall of the freezer body, a slide groove is provided on the guide bar, and the second connecting rod side is embedded in the slide groove and is slidably connected to the guide bar.

[0012] Furthermore, a limiting strip is provided on the guide strip to limit the second connecting rod in the sliding groove.

[0013] Furthermore, the heating unit includes a resistance wire.

[0014] Furthermore, a water guide groove connected to the refrigeration unit is provided on the inner wall of the freezer body.

[0015] Furthermore, a water receiving tray is provided at the bottom of the freezer body, and the water guide groove is connected to the water receiving tray.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] A defrosting device is arranged beside the refrigeration unit, and is connected to the first connecting rod, the second connecting rod and the screw mechanism. Under the action of the motor, the fan assembly can move horizontally or vertically on the inner wall of the freezer body, directing hot air to the refrigeration unit to melt the frost on the surface of the refrigeration unit. Compared with a fixed defrosting structure, the surface of the refrigeration unit can be defrosted more evenly.

[0018] The screw mechanism, the second connecting rod and the first connecting rod are hinged in such a manner that the fan assembly can be placed on the upper side of the refrigeration unit after defrosting is completed, thereby avoiding obstruction of the refrigeration unit by the fan assembly and not affecting subsequent normal use of the refrigeration unit.
