Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0024] In this embodiment, Figure 1-4 The utility model includes a shell 1, a light box 2 is embedded in the upper part of one side wall of the shell 1, a thermostat 3 is embedded in the side wall of the shell 1 below the light box 2, an electric heating defogger glass door 4 is arranged on the side wall of the shell 1 below the thermostat 3, an evaporation fan 5 is arranged at the top of the shell 1 inside the electric heating defogger glass door 4, a first ladder frame 6 is arranged on both inner walls of the shell 1 below the evaporation fan 5, a second ladder frame 7 is arranged on both sides of the middle of the inner wall of the shell 1 between the first ladder frame 6, and the first ladder frame 6 and the second ladder frame 7 are arranged on the first ladder frame 6.

A fixed adjustable ground nail 12 is provided in the middle of the connecting seat 11, and a universal wheel 13 is provided at the lower end of the shell 1 on the inner side of the connecting seat 11. Two evaporation drainage boxes 14 are provided on the back side wall of the shell 1 facing the thermostat 3, two compressors 15 are provided on the upper end of the shell 1, and a rat-proof net 16 is provided on the back side wall of the shell 1 on the side of the compressor 15.

[0025] Among them, a controller 17 is connected to the inner wall of the shell 1 located on the inner side of the light box 2 by screws, a memory 18 is connected to the inner wall of the shell 1 on the side of the controller 17 by screws, and a network connection module 19 is connected to the inner wall of the shell 1 on the side of the memory 18 away from the controller 17 by screws. The outer wall surface of the shell 1 and the surface of the electrically heated defog glass door 4 are coated with a rare earth nano sunscreen layer. The rare earth nano sunscreen layer can make the outdoor freezer have excellent sun protection performance, so that the outdoor freezer can withstand sunlight exposure outdoors.

[0026] The electric heating defogger glass door 4 is connected to the side wall of the shell 1 through a return spring hinge. When there is no external force after the electric heating defogger glass door 4 is opened, it can rebound and close under the action of the return spring. The evaporating fan 5 is fixed to the top of the shell 1 through a slot. The temperature sensing contact of the thermostat 3 is on the inner wall of the shell 1 on the side of the evaporating fan 5. The electric heating defogger glass door 4 is an existing industrial opening technology. The electric heating defogger glass door 4 is a three-layer hollow tempered glass structure with good thermal insulation performance.

The upper end of the connecting seat 11 is connected to the lower end of the shell 1 by screws, the upper part of the fixed and adjustable ground nail 12 is connected to the middle part of the connecting seat 11 by threads, and the upper end of the universal wheel 13 is connected to the lower end of the shell 1 by bolts. The freezer can be conveniently moved through the universal wheel 13. The fixed and adjustable ground nail 12 is rotated downward so that the lower end of the fixed and adjustable ground nail 12 contacts the ground, so that the fixed and adjustable ground nail 12 cooperates with the connecting seat 11 to provide auxiliary support for the freezer, and the universal wheel 13 can be prevented from moving, thereby ensuring the stability of the freezer.

[0028] Among them, the compressor 15 is connected to the upper end of the shell 1 by bolts, the rodent-proof net 16 is connected to the side wall of the shell 1 by screws, and the drain outlet of the compressor 15 is connected to the evaporative drain box 14 by a pipe. The dual compressor 15 structure setting of the freezer can make the freezer have excellent refrigeration efficiency and temperature control efficiency. The excess moisture of the compressor 15 can be discharged to the evaporative drain box 14 through the pipe, evaporated and discharged, and will not condense inside the freezer.

[0029] Among them, the network connection module 19 and the memory 18 are electrically connected to the controller 17, the light strip 10, the light box 2 and the thermostat 3 are electrically connected to the controller 17, the evaporating fan 5, the compressor 15 and the electrically heated defogger glass door 4 are electrically connected to the thermostat 3, and the network connection module 19 can connect the freezer to other devices through the network, so that the freezer can be controlled by the APP, and the display content can be freely set in the light box 2, and the display is controlled by the controller 17. The light strip 10 can illuminate the inside of the freezer when working.

[0030] Working principle: The outer wall surface of the shell 1 of the outdoor freezer and the surface of the electrically heated defogger glass door 4 are coated with a rare earth nano sunscreen layer. The rare earth nano sunscreen layer can make the outdoor freezer have excellent sun protection performance, so that the outdoor freezer can withstand sunlight exposure outdoors. The temperature inside the freezer can be set through the thermostat 3. The temperature sensing contact of the thermostat 3 is on the inner wall of the shell 1 on the side of the evaporating fan 5. The thermostat 3 can obtain the temperature information inside the freezer through the temperature sensing contact, and then adjust the compressor 15 and the evaporating fan 5 to work, so as to adjust the temperature inside the freezer. The dual compressor 15 structure setting of the freezer can make the freezer have excellent refrigeration efficiency and temperature control efficiency. The excess water of the compressor 15 can be discharged to the evaporating drainage box 14 through the pipeline, evaporated and discharged, and will not condense inside the freezer. A travel switch is embedded in the side wall of the shell 1 which contacts the inner side of the upper part of the hot defogger glass door 4 and is linked to the evaporative fan 5. In this way, when the electrically heated defogger glass door 4 is opened, the travel switch is not pressed, and the evaporative fan 5 stops working. When the electrically heated defogger glass door 4 is closed, the travel switch is pressed by the electrically heated defogger glass door 4, and the evaporative fan 5 continues to work. In this way, the evaporative fan 5 can be prevented from sucking hot air outside the freezer when the electrically heated defogger glass door 4 is opened, which can effectively reduce temperature loss and achieve energy-saving effects. The freezer can be connected to the network with other devices through the network connection module 19, so that the freezer can be controlled by the APP, and the display content can be freely set in the light box 2, and the display is controlled by the controller 17. The light strip 10 can illuminate the freezer when it is working to facilitate the placement of items.
