Problems solved by technology

[0005] However, in the cryogenic container with such a structure, although the pressure regulating cover that opens and closes the above-mentioned regulating port can be opened in conjunction with the turning operation of the door opening and closing device, before the turning operation of the door opening and closing device, the inside of the storage room The air pressure is still low relative to the external atmospheric pressure, so there is a problem that a large operating force is required when the door opening and closing device is turned and operated.

Abstract

The present invention provides a cooling container with a heat insulating door which can be opened-and-closed or operated with smaller operating force. The cooling container (1) is provided with the following components: a heat insulating box (3) which closes the opening arranged on the storeroom (4) with the heat insulating door (5); a door open device (7) which helps the opening of the heat insulating door (5); and an air pressure regulating device (29) which actuates according to the pressure difference between the outer part (27) and the interior part (28) of the heat insulating box, and the air pressure regulating device (29) comprises the following components: an air pressure regulating gateway (30) which communicates the outer part (27) of the heat insulating box with the interior part (28) of the heat insulating box; and a check valve (31) which is arranged in the air adjusting gateway (30) to control the air circulating, and the check valve (31) is arranged at a position that is nearer to the outside (27) of the heat insulating box comparing with the interior part (28) of the heat insulating box.

Description

technical field [0001] The present invention relates to a cooling container for cooling stored items by a cooling mechanism provided inside. Background technique [0002] Conventionally, in this type of cooling container, since the air inside the storage compartment is cooled, the air pressure inside the storage compartment becomes lower than the external atmospheric pressure, making it difficult to open the insulating door. [0003] As a method to solve this problem, a heat-insulating box having a storage room with an opening that can be opened and closed freely closed by an insulating door is provided in the cryogenic container, and the above-mentioned heat-insulating door and the heat-insulating box are rotatably installed to open and close the above-mentioned heat-insulating box. The hot door opening and closing device, the adjustment port provided on the above-mentioned insulating door to communicate the outside with the above-mentioned storage room, and the pressure ad...
