Detailed implementation mode
[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.
[0026] Please refer to Figure 1 , 2 , 3, 4, 5, 6, 7 and 8, the present invention provides a technical solution: a freezer with a defrosting function, including: a box body 1, the box body 1 is composed of a shell, a lining, a heat insulation layer and a sealing strip. Among them, a refrigeration system is provided at the bottom of the box body 1, and the system includes a refrigerant, a compressor, a condenser and an evaporator; the refrigerant circulates under the action of the compressor, absorbs heat from the inside of the freezer, and then discharges it to the external environment, thereby reducing the temperature inside the freezer; the air duct 3 is fixedly connected to one side of the box body 1, and a defrosting heat dissipation component is provided at one end of the air duct 3. A fan 4 is installed at one end of the air duct 3, and the air inlet of the fan 4 corresponds to the heat dissipation part of the condenser, which is convenient to send the dissipated heat into the box body 1 through the air duct 3. A sealing plug 7 for controlling the on-off of the heat dissipation air flow is slidably arranged up and down at the end of the air duct 3, and a heating part is arranged inside the air duct 3; a material storage frame 10 is placed inside the box body 1, a bottom net 11 is arranged at the bottom of the box body 1, and hanging members 12 for adjusting the height of the bottom net 11 inside the material storage frame 10 are rotatably installed on both sides of the bottom net 11.
[0027] It should be noted that when the present invention is in use, the material storage frame 10 can move inside the box body 1, and according to the amount of items, the storage space size of the material storage frame 10 is adjusted by adjusting the hanging position of the hanging member 12 and the material storage frame 10, which is convenient for taking and placing the materials inside it. When defrosting the inside of the box body 1, the fan 4 sends the heat dissipated by the evaporator and the bottom air into the air duct 3. The air contacts the heating part inside the air duct 3, so as to heat the air inside the air duct 3. The sealing plug 7 moves upward, and then the air enters the heat dissipation pipe 16, and the inside of the box body 1 is defrosted through the air outlet nozzles 17 with different directions.
[0028] Please refer to Figure 1 , 2As shown in FIGS. 6, two sealing covers 2 are rotatably connected to the top of the box body 1. A drain pipe 18 is fixedly connected to the bottom of the inner wall of the box body 1 for discharging the water generated by defrosting. A valve is installed in the middle of the drain pipe 18.
[0029] It should be noted that in the present utility model, the sealing cover 2 is hinged to the top of the box body 1, and a sealing strip adapted to the box body 1 is provided at the bottom of the sealing cover 2. The bottom of the inner wall of the box body 1 is inclined downward towards one end of the drain pipe 18. And during the defrosting operation, the valve is opened, and the water after defrosting is discharged to the outside through the drain pipe 18, which is convenient for discharging the internal water.
[0030] Please refer to Figure 2 、 4 As shown in FIGS. 7, the heat dissipation component includes a heat dissipation pipe 16 fixedly connected inside the box body 1. Air outlet nozzles 17 are installed in a spiral distribution on the outer side of the heat dissipation pipe 16. The fan 4 is fixedly connected to the bottom of the box body 1. Electric telescopic rods 8 are fixedly connected to both sides of the air duct 3. The output end of the electric telescopic rod 8 is fixedly connected to a cross beam 9, and the cross beam 9 is fixedly connected to the sealing plug 7. The heating part includes two partition plates 5 alternately arranged on both sides inside the air duct 3, and an electric heating wire 6 is fixedly connected between two adjacent partition plates 5.
[0031] It should be noted that in the present utility model, the waste heat of the condenser in the fan 4 and the air inside the box body 1 are drawn into the air duct 3. Under the blocking action of the partition plate 5, the air travels along an S-shaped path inside the air duct 3. Then the electric telescopic rod 8 drives the sealing plug 7 to lift and lower through the cross beam 9, and the sealing plug 7 opens the opening connecting the air duct 3 and the heat dissipation pipe 16, facilitating the air to enter the heat dissipation pipe 16 from the air duct 3 and then dissipating through the air outlet nozzles 17 on the outer side of the heat dissipation pipe 16. Because the angle pedals are arranged in a spiral pattern on the outer side of the heat dissipation pipe 16, it can defrost different positions and angles. After defrosting, the air can dry the inside of the box body 1 and evaporate and discharge the internal moisture.
[0032] Please refer to Figure 5 、 6 As shown in FIGS., two limiting rods 19 for supporting the storage frame 10 are symmetrically and fixedly connected inside the box body 1. The hanging member 12 includes a threaded pipe 14 with symmetric threads provided at both ends inside. A hook 13 is threadedly connected to the top of the threaded pipe 14, and a bottom rod 15 is threadedly connected to the bottom of the threaded pipe 14. The bottom rod 15 is rotatably connected to the bottom net 11 through a ring.
[0033] It should be noted that the storage frame 10 of the present utility model is placed between two limit rods 19. The storage frame 10 can slide on the top of the limit rods 19, making its structure more flexible. When it is necessary to adjust the height of the bottom net 11, the hook 13 is hung at different heights on the outside of the storage frame 10 to adjust the height of the bottom net 11, so that the storage space inside the storage frame 10 can be adjusted. And by rotating the suspension member 12, since opposite threads are provided at both ends of the suspension member 12, under the action of the threads, the bottom rod 15 and the hook 13 can be adjusted to the middle or both ends of the threaded pipe 14 at the same time, thereby adjusting the height of the bottom net 11.
