Temperature difference type storage box

Abstract

The invention relates to a temperature difference type storage box, which belongs to household necessities and is widely applied for residents in a region, where outdoor temperature is lower than zero DEG C in winter, to store vegetables and fruits at a low temperature in winter. The temperature difference type storage box comprises a cooling tube (1), a circulating pump (2), an insulation can structure (3), an insulation door (4), a circuit board (7), an electronic temperature sensor (8), a cooling box structure (9) and a liquid adding box structure (12), the exchange speed of liquid in the cooling tube (1) and the cooling box structure (9) is controlled by transferring a temperature control instruction from a temperature control structure (11) to the circuit board (7) and controlling the working states of an electric motor (10) and the recycle pump (2) by the circuit board (7) so that the temperature in a storage space (5) is kept consistent with the set temperature of the temperature control structure (11). The temperature difference type storage box has the advantages of low manufacture cost, great storage space, low electricity consumption and adjustable temperature.

[0002] A temperature-difference type storage box is a household necessity, and can be widely used in low-temperature storage of vegetables and fruits in winter for residents in areas where the outdoor temperature is below zero degrees Celsius in winter. Currently, products and methods for low-temperature storage of vegetables and fruits in winter in residents' lives There are several methods of storage in the insulation layer of the refrigerator, storage in the crypt, and storage in scattered storage. The storage of the insulation layer of the refrigerator is more convenient, but it has the disadvantages of high product and storage costs, small storage space, and large power consumption. Storage has the advantages of large space and no consumption point, but it has the disadvantages of excessive initial investment, uncontrollable temperature, and inconvenient access. The scattered storage method has the disadvantages of small storage quantity, excessive environmental influence factors, uncontrollable temperature, Disadvantages of poor storage effect
