Claims

[Scope of utility model registration request]

In a freezer where the freezer body is equipped with an internal cooler for internal cooling and an auxiliary cooler for defrosting,
A parallel circuit in which the internal cooler and an auxiliary cooler are connected in parallel is provided in the refrigeration cycle of the freezer main body, and a refrigerant inflow passage of the auxiliary cooler is provided with a refrigerant inflow passage into the auxiliary cooler during defrosting operation. A defrosting on-off valve that shuts off the inflow of refrigerant is interposed, and the auxiliary cooler is arranged at a peripheral portion of the upper opening of the freezer main body, and a first cooling section is arranged at the upper part of the freezer main body. 2. A freezer characterized in that a second cooling section is provided, and a defrosting heater that is energized during the defrosting operation is attached to the first cooling section.
