Abstract
The utility model belongs to the technical field of freezers, particularly relates to a power failure emergency device for a freezer and provides a power failure emergency device for a freezer, which can still keep the freezing effect for a period of time during power failure. The utility model adopts the technical solution that the device comprises a frist cavity, a second cavity, heat-insulating walls, a freezing device, a switch valve, a controller, a liquid nitrogen container and a liquor feeding pipe; the frist cavity and the second cavity are provided with the heat-insulating walls; the freezing device is arranged in the second cavity; the liquid nitrogen container is arranged in the frist cavity; one end of the liquor feeding pipe is connected with the liquid nitrogen container, and the other end is connected with the switch valve; the switch valve is connected with the freezing device; the second cavity is provided with the controller; the controller is connected with the switch valve; and the freezing device is arranged in the second cavity. In case of power failure, the controller sends an actuating signal to the switch valve, and then liquid nitrogen in the liquid nitrogen container can be enabled to flow to the freezing device, so that a freezing effect can be provided for the freezer continuously.
Description
Technical field
The utility model belongs to the freezer technical field, particularly relates to a kind of freezer rescue apparatus during stoppage of power supply.
Background technology
Freezer is used for food, medicine, and freezing processing and the refrigeration of machinery, it makes the certain low temperature of indoor maintenance by artificial cooling.Freezer needs the refrigerating effect of keeping of power supply, in case have a power failure, freezer can't work, and causes the tremendous economic loss.
Summary of the invention
The defective that the utility model exists in order to overcome prior art, it is the freezer rescue apparatus during stoppage of power supply that still can keep a period of time refrigerating effect in power failure that the purpose of this utility model is to provide a kind of.
The technical solution that the utility model adopts comprises the 1st cavity, the 2nd cavity, insulated wall, freezing plant, switch valve, controller, liquid nitrogen container and feed tube, described the 1st cavity and the 2nd cavity are provided with insulated wall, be provided with freezing plant in the 2nd cavity, the 1st cavity is provided with liquid nitrogen container, one end of feed tube is connected with liquid nitrogen container, and the other end is connected in switch valve, and switch valve is connected with freezing plant, the 2nd cavity is provided with controller, and controller is connected in switch valve.
Compared with prior art, the beneficial effect that the utility model has is: by be provided with freezing plant in the 2nd cavity, when occuring to have a power failure, controller sends actuating signal to switch valve, make the liquid nitrogen in liquid nitrogen container flow into freezing plant, can continue as freezer refrigerating effect is provided.
