Freezers are commonly found in supermarkets, convenience stores, restaurants, food processing plants and other places, and are used to store refrigerated food, frozen food or other items that need to be kept at low temperatures.
[0003] Existing refrigerators are usually equipped with a door. When you need to take items out of the refrigerator, you need to open the door. At this time, the part of the refrigerator near the door is exposed to the outside, and the cold air inside the refrigerator will leak to the outside, causing the temperature to rise and the insulation effect to deteriorate, affecting the preservation effect of food. The temperature increase will cause the refrigeration system to require more energy to restore the low temperature state, increasing energy consumption and causing energy waste. Utility Model Content

[0021] See also Figure 1-4The utility model provides a technical solution: a refrigerator with good heat preservation performance, comprising a refrigerator body 1, a cabinet door 2 hinged on the surface of the refrigerator body 1 and a refrigerating chamber 3 equidistantly arranged inside the refrigerator body 1, a PE transparent inner door 4 is hinged inside the refrigerator body 1, and the surface of the PE transparent inner door 4 is equidistantly provided with a pick-up and release groove 5, the size of the pick-up and release groove 5 matches the size of the refrigerating chamber 3, a fixed cylinder 6 is fixedly installed inside the PE transparent inner door 4, a reel 7 is rotatably connected inside the fixed cylinder 6, a PE transparent rolling curtain 8 is wound on the surface of the reel 7, a coil spring is installed at the connection between the reel 7 and the fixed cylinder 6, under normal conditions, the reel 7 is reeled up to the PE transparent rolling curtain 8 through the elasticity of the coil spring, a sliding rod 9 is fixedly connected to the end of the PE transparent rolling curtain 8 away from the reel 7, the outer surfaces of the sliding rod 9 and the PE transparent rolling curtain 8 are both movably connected inside the pick-up and release groove 5, a fixed block 10 is fixedly connected to the inner center of the sliding rod 9, the top and bottom of the fixed block 10 are fixedly connected to the sliding block 11, and the outer surface of the sliding block 11 is slidably connected to the PE The inner center of the sliding block 11 is provided with a sliding rod 12, and the inner center of the sliding block 11 is provided with a limiting groove 111 matching the sliding rod 12. The sliding block 11 is slidably connected to the outer surface of the sliding rod 12 through the limiting groove 111, and the outer surface of the sliding rod 12 is movably sleeved with a spring 13. Both ends of the sliding block 11 are fixedly connected to the limiting plates 14, and the outer surface of the limiting plates 14 is fixedly connected to the inside of the PE transparent inner door 4. The surface of the sliding rod 9 is provided with a square groove 15. By setting the PE transparent inner door 4, when it is necessary to take out the items in the cold storage room 3, the corresponding two sliding rods 9 can be slid to both sides, so that the user can more conveniently take out the items in the refrigerator body 1 without fully opening the PE transparent inner door 4, saving time and energy. Since the PE transparent inner door 4 does not need to be fully opened to take out the items, the cold air loss in the refrigerator body 1 is less, which helps to keep the temperature of the cold storage room stable, thereby saving energy and improving the heat preservation performance of the refrigerator body 1.
[0022] A rotating groove 16 is provided on the side of the sliding rod 9, and a fixed shaft 17 is fixedly connected to the inside of the rotating groove 16.

Since the PE transparent inner door 4 does not need to be fully opened to take out the items, the cold air loss in the refrigerator body 1 is less, which helps to keep the temperature of the refrigerator chamber stable, thereby saving energy and improving the heat preservation performance of the refrigerator body 1. If small items are to be taken or placed in the refrigerator body 1, the sliding rod 9 can be driven to automatically open to both sides through the abutment between the object and the roller 18. The user does not need to pull the sliding rod 9 with great effort, making the process of taking or placing items more convenient, eliminating the step of manually opening, and improving work efficiency.
