Claims

[Claims for Utility Model Registration] (1) A partition wall divides the space into two spaces each having a storage chamber, and the partition wall has a communication hole that communicates with the two storage chambers. A housing having an exhaust hole that communicates with the outside, a damper that opens and closes the exhaust hole of each storage chamber individually, and a damper that is provided in relation to each storage chamber and injects liquefied gas and sends the cold heat to the storage chamber. a damper comprising a nozzle and a liquefied gas supply means that alternately switches and supplies liquefied gas to one of the nozzles, and is provided in an exhaust hole of one of the storage chambers from which the liquefied gas is injected from the nozzle; is closed, the damper provided in the exhaust hole of the other storage chamber is opened, and the dampers provided in each exhaust hole are alternately opened and closed according to the supply of liquefied gas to each nozzle. A freezing device that uses liquefied gas. (2) A housing having an axis extending vertically and having an exhaust hole formed in a part of the circumference, a precooling chamber provided within the housing and communicating with the exhaust hole, and a freezing chamber partitioned from the precooling chamber. a partition wall that forms a chamber, is provided with a communication hole that communicates the precooling chamber and the freezing chamber, and is movable angularly with a vertical axis; a nozzle that is provided in the housing and faces into the freezing chamber; A freezing device using liquefied gas, comprising: a liquefied gas supply source that supplies liquefied gas to a nozzle; and a holding means provided on a partition wall and holding an article to be frozen.
