Description

Technical Field

[0001] The utility model relates to a defrosting structure, in particular to a reinforced commercial freezer defrosting structure, belonging to the technical field of commercial freezers. Background Art

[0002] Commercial freezers are refrigeration equipment designed for commercial use, with the characteristics of large capacity, efficient refrigeration, and durability. Commercial display cabinets usually have glass door designs that can visually display the frozen items inside, and are suitable for supermarkets, convenience stores and other places where goods need to be displayed.

[0003] Most commercial frozen display cabinets on the market use electric heating for defrosting. Simply using electric heating without optimizing the placement space of the evaporator often leads to unclean defrosting, especially at the upper part of the evaporator far from the heating tube, where residual ice is left. The usual treatment method is to increase the power of the heating tube or increase the defrosting time, which will cause the temperature of the freezer to rise too much, affecting the preservation of the food in the display cabinet, and increasing the power consumption. Therefore, an enhanced defrosting structure for commercial frozen cabinets is proposed. Utility Model Content

[0030] A driving assembly 20 is disposed on the top of the cover plate 14, and the driving assembly 20 includes a driving box 21, a support plate 22, a motor 23, a screw rod 24, a slider 25 and a second windshield plate 26;

[0031] The inner wall of the drive box 21 is fixedly connected to a support plate 22, and a motor 23 is installed on the upper surface of the support plate 22. The output shaft of the motor 23 is fixedly connected to one end of a screw rod 24, and the screw rod 24 is rotatably connected to the bottom of the support plate 22. The outer wall of the screw rod 24 is threadedly connected to a slider 25, and the slider 25 is slidably connected to the inner wall of the drive box 21. A second wind shield 26 is fixedly connected to one side of the slider 25.

[0032] In this embodiment, specifically: the driving box 21 is fixedly connected to the upper surface of the cover plate 14 .

[0033] In this embodiment, specifically: the second wind shield 26 is slidably connected to the inner wall of the slide groove 15, and the motor 23 drives the screw rod 24 to rotate during the defrosting process, so that the second wind shield 26 moves downward along the slide groove 15, half-wrapping the evaporator 18 to reduce heat loss. After the defrosting is completed, the motor 23 rotates in the opposite direction, the second wind shield 26 rises, and the system starts to cool.

[0034] In this embodiment, specifically: the main assembly 10 further includes a fixing plate 12 and a fan 13;

[0035] Two fans 13 are symmetrically mounted on one side of the fixed plate 12 , and the fans 13 drive the air flow. The fans 13 stop working during the defrosting process.

[0036] In this embodiment, specifically: the fixing plate 12 is fixedly connected to one end of the air duct 11 .

[0037] In this embodiment, specifically: an air outlet 17 is provided at one end of the air duct 11, and one end of the air outlet 17 is connected to the interior of the freezer.

[0038] In this embodiment, specifically: an evaporator 18 is installed on the inner wall of the air duct 11, and cooling is performed through the evaporator 18. The fan 13 is used to drive the air flow. The air passes through the evaporator 18 to generate cold air, which is discharged from the air outlet 17 to reduce the internal temperature of the freezer.

[0039] In this embodiment, specifically: a heater 19 is installed at the bottom of the inner wall of the air duct 11, and heating tubes 110 are evenly installed on the front surface of the heater 19. The heating tubes 110 are arranged below the evaporator 18. Heating and defrosting are performed by the heater 19 and the heating tubes 110. After the heating tubes 110 are heated, the hot air rises to the top of the evaporator 18, gathers at the top of the evaporator 18 to heat the upper air, thereby melting the frost on the surface of the upper evaporator 18.

The air passes through the evaporator 18 to generate cold air, and the air is discharged from the air outlet 17 to reduce the temperature inside the freezer. When frost forms on the surface of the evaporator 18, the fan 13 stops working, and heating and defrosting are performed through the heater 19 and the heating tube 110. During the defrosting process, the motor 23 drives the screw rod 24 to rotate, so that the second wind shield plate 26 moves downward along the slide slot 15 to half-wrap the evaporator 18. At the same time, the heater 19 starts to heat, and the hot air rises to the top of the evaporator 18 and gathers at the top of the evaporator 18 to heat the upper air, thereby melting the frost on the surface of the upper evaporator 18. After defrosting is completed, the second wind shield plate 26 rises, and the evaporator 18 and the fan 13 work at the same time, and the system starts to refrigerate. During the defrosting process, the heat of the heating evaporator 18 can be prevented from being transferred to the cabinet, affecting the temperature inside the cabinet, and then affecting the freshness of the food. At the same time, the heat of the heater 19 is fully utilized to improve the defrosting efficiency, enhance the energy utilization rate, and reduce the waste of heat.
