Description

Technical Field

[0001] This utility model relates to the field of food refrigeration technology, and more specifically, to an energy-saving device for refrigeration. Background Technology

[0002] Food refrigeration is an important method of food preservation, aiming to slow down the growth and reproduction of microorganisms and chemical reactions in food by lowering the temperature, thereby extending the freshness and shelf life of food. When food is placed in a refrigerator or cold storage, the lower temperature environment can inhibit the activity of bacteria, molds, and other pathogens, reducing their spoilage and deterioration.

[0003] As people's pursuit of quality of life continues to rise, consumers are demanding increasingly stringent requirements for food safety and freshness. Traditional food refrigeration methods, such as large refrigerators, large refrigerated trays, and crushed ice preservation, while playing an important role in large-scale commercial applications, have some limitations, particularly in small convenience store environments. These traditional refrigeration devices often occupy too much space due to their large size, posing a significant challenge for small retail spaces where space is at a premium; at the same time, they typically have high energy consumption, increasing operating costs, and improper maintenance can lead to hygiene problems, affecting food safety and quality.

An outer pot 3 is provided on the outer side of the inner pot 2, and the bottom of the inner pot 2 is fitted against the inner wall of the bottom of the outer pot 3. A controller 16 is embedded in the lower outer shell 7. A side coil 10 is wrapped around the outer wall of the outer pot 3. A bottom coil 11 and a temperature sensor 12 are fixedly connected to the bottom of the outer pot 3. The side coil 10... The base plate 8 is connected to the base tube 11. Multiple columns 21 are fixedly connected to the top of the base plate 8. A refrigeration component is set on the top of the base plate 8. A support plate 4 is fixedly connected to the top of the columns 21. The outer pot 3 is fixedly connected to the support plate 4 through a bracket. The upper outer shell 6 and the lower outer shell 7 are made of plastic and are connected by screws. The inner pot 2 and the outer pot 3 are both made of stainless steel. The outer pot 3 is fixedly connected to the upper outer shell 6. The temperature sensor 12 is located inside the base tube 11 and is electrically connected to the controller 16.

[0025] The refrigeration assembly includes a compressor 13 fixedly connected to the top of the base plate 8. The compressor 13 contains refrigerant and is connected to a dryer filter 15 via copper tubing. A throttling component 14 is connected to the dryer filter 15 and is connected to a side coil 10. An insulation layer 5 is provided on the outside of the side coil 10 and is fixedly connected to the upper outer shell 6. The refrigeration assembly also includes a heat sink 17 fixedly connected to the top of the base plate 8, and a heat sink outer shell 1 is fixedly connected to the top of the heat sink 17. 8. A condenser 19 is embedded in the heat dissipation shell 18. A fan 20 is fixedly connected to the inner side wall of the heat dissipation base 17. The heights of the two opposite side walls of the heat dissipation base 17 are different. The fan 20 is inclined relative to the horizontal plane. A partition 9, a protective net 23 and multiple feet 22 are fixedly connected to the bottom of the base plate 8. The protective net 23 is located below the fan 20.

[0027] The working principle of this energy-saving refrigeration device is as follows: Food to be refrigerated is placed in the inner pot 2, and the device is started. The compressor 13 begins to work, allowing the refrigerant to absorb heat from the inner pot 2 and outer pot 3 through the side coil 10 and bottom coil 11. This heat is then released to the surrounding environment through the condenser 19 and the rotation of the fan 20. The temperature of the outer pot 3 is monitored in real time by the temperature sensor 12 at the bottom of the outer pot 3. The temperature of the food in the inner pot 2 is controlled within a set range by starting and stopping the refrigeration system, thus achieving the purpose of refrigeration.

[0028] By operating the fan 20, a negative pressure is created inside the lower outer casing 7. External airflow enters from the air inlet 24 at the bottom of the compressor 13, passes through the condenser 19, absorbs the heat from the condenser 19, and is discharged from the protective net 23, thus improving the heat exchange efficiency. By setting the fan 20 to be tilted to the horizontal plane, the airflow is tilted and blown to the bottom support surface, achieving a quieter effect.

[0029] In this embodiment, the use of compressor 13 for refrigeration avoids the hygiene and replacement problems of traditional crushed ice preservation. The separate design of inner pot 2 and outer pot 3 provides a more convenient way to clean and replace the refrigerator compared to a larger refrigerator. The outer pot 3, together with the side coil 10 and bottom coil 11 on it, plays a role in uniform heat dissipation, achieving a three-dimensional refrigeration effect, making the cooling fast and uniform.

Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
