Electric-field freshness preservation refrigerator with shielding function

Abstract

The invention discloses an electric-field freshness preservation refrigerator with a shielding function and relates to the technical field of electric-field freshness preservation of refrigerators. The refrigerator disclosed by the invention comprises a refrigerator case body and a refrigerator door body, wherein the refrigerator case body is in hinged connection to the refrigerator door body by an upper metal hinge and a lower metal hinge respectively, and the refrigerator case body comprises multiple compartments; electric-field release devices are installed on the top face inner wall or the bottom face inner wall of the compartments; the multiple electric-field release devices are electrically connected to a power source device; a metal shielding layer is disposed on the shell inner wall of the refrigerator case body and the shell inner wall of the refrigerator door body; and the metal shielding layer is electrically connected to a ground electrode. The refrigerator disclosed by the invention has the beneficial effects that an electric field is generated inside the refrigerator by the electric-field release devices, and the metal shielding layer is constructed in the refrigerator case body and the refrigerator door body, so worsening of electric-field freshness preservation effects of the refrigerator caused by overlaying of an external electric field can be effectively avoided, and freshness preservation effects of fruits and vegetables in the refrigerator can be improved.

Description

technical field [0001] The invention belongs to the technical field of refrigerator electric field preservation, in particular to an electric field preservation refrigerator with shielding function. Background technique [0002] The experimental results show that the electric field can better maintain the quality of fruits and vegetables, and the preservation effect of the electric field is mainly related to the strength of the electric field. The electric field strength has a certain effect on the preservation of fruits and vegetables within a certain range. [0003] At present, electric field fresh-keeping refrigerators have been sold in the market, and fresh-keeping refrigerators generally have a set of electric field generating devices to generate an electric field of a certain intensity to keep fruits and vegetables fresh. Since the electric field strength is known as a vector, and the electric field strength is superimposed, that is to say, the fresh-keeping electric f...

AI Technical Summary

Problems solved by technology

[0006] The object of the present invention is to provide a kind of electric field fresh-keeping refrigerator with shielding function, through the electric field release device to make the electric field in the refrigerator, and a metal shielding layer is built in the refrigerator box and the refrigerator door, which can effectively avoid the damage caused by the external electric field. The reduction of the electric field fresh-keeping effect of the refrigerator caused by the superposition solves the problem that the existing electric field fresh-keeping refrigerators do not have the ability to shield the external electric field and prevent the internal electric field from overflowing
