Abstract

The invention discloses a freezer for preventing power failure, which comprises a cabinet body and a cabinet door, the cabinet door is rotatably installed on the cabinet body, an inner cavity is arranged in the cabinet body, and two sides of the inner cavity are symmetrically arranged inside The starting mechanism, the starting mechanism includes a cold semiconductor sheet and a hot semiconductor sheet, the cold semiconductor sheet and the hot semiconductor sheet are connected in series, a main line is arranged at the bottom of the cabinet, a pair of electromagnets are connected in series on the main line, and the hot semiconductor sheet is connected in series. The steel sheet and the cold semiconductor sheet are connected in series with steel pipes, and electric wires are arranged inside the steel pipes, and the steel pipes are arranged opposite to the electromagnet. The present invention utilizes the difference in temperature inside and outside the freezer, and according to the Seebeck effect, connects the cold semiconductor sheet and the hot semiconductor sheet in series, and a current will be generated on the circuit connected in series, and the thermal effect of the current will cause the memory metal to be heated and stretched, so that the lid will be tightly closed. It fits closely with the cabinet body to avoid leakage of internal cold air and allow enough time for timely power on.

Description

technical field

[0001] The invention relates to the technical field of freezers, in particular to a freezer that prevents power failure. Background technique

[0002] Freezers are also refrigerators and freezers. All evaporator tubes of high-quality freezers are made of high-quality copper coils and processed into wide-faced irregular shapes. The surface of the stainless steel plate is smooth and clean, and the thickness of the whole plate is uniform. The appearance of the freezer is flat and firm, and freezing can keep food fresh for a long time.

[0003] The frozen food in the freezer needs to be kept frozen at all times, and the freezer needs to be powered on at all times to keep it frozen. If there is a power outage without knowing it, the freezer generally relies on the inconsistent air pressure caused by the inconsistent internal and external temperatures to achieve the door to the cabinet body. Sealing effect, if the freezer is not powered on in time, the internal co...
