Storage box with refrigeration and vacuum preservation functions

Abstract

The invention discloses a storage box with refrigeration and vacuum preservation functions. The storage box comprises a box body and a box door. The refrigerating system comprises a cold conduction block and a semiconductor chip, and the semiconductor chip is used for refrigerating or heating, so that the temperature in the inner container is reduced or increased; and the vacuum preservation system comprises a vacuum cover, a vacuum pump and a circuit board, and two vacuum switches on the circuit board cooperatively control the working state of the vacuum pump, so that the vacuum in the storage box is kept within a reasonable vacuum degree range. The refrigerating system and the vacuum storage system are arranged at the same time, the refrigerating system is used for achieving the refrigerating and fresh-keeping effect or the heating and unfreezing effect on food in the box body, the vacuum storage system is used for vacuumizing the box body to achieve the vacuum fresh-keeping effect, and the two environmental factors including the oxygen content and the temperature of the storage box can be controlled at the same time; the storage box can store various food materials at the same time, and the storage time is long.

Description

technical field [0001] The invention relates to the technical field of storage box products, in particular to a storage box with refrigeration and vacuum preservation functions. Background technique [0002] With the advancement of science and technology and the continuous improvement of living standards, people have higher requirements for the storage of items. For example, raw and cooked foods such as meat, aquatic products, and egg products need to be protected from corruption, while dried goods, dried fruits, medicinal materials, and clothing need to be protected from insects, moisture, and mildew. All in all, different foods require corresponding storage environments, but generally speaking, the main two environmental factors are to control the oxygen content and temperature.

Problems solved by technology

[0003] Storage boxes are utensils used by many families, whether in rural areas or cities, almost every household uses them. However, most storage boxes on the market simply seal up items for storage. Because there is a certain amount of air in the box, Therefore, food stored for a long time is prone to oxidation and deterioration.

Although in the prior art there are also storage box products that can extract the air in the box so as to play a vacuum preservation function (that is, control the oxygen content), they cannot meet the user's refrigeration and preservation needs (that is, control the temperature), so that it cannot Store raw and cooked foods such as meat, aquatic products, and egg products, as well as fresh ingredients such as fruits and vegetables

In general, the existing technical solutions can only achieve vacuum or refrigeration storage. Under a single storage condition, food or other substances cannot be stored for a long time, especially those with high storage conditions cannot be stored for a long time.
