Claims

[Scope of utility model registration request]

(1) A wind direction rectification chamber and a damper room are placed adjacent to a thawing chamber partitioned left and right by a partition wall in the longitudinal direction, and the damper chamber is divided into an upper suction chamber and a lower blowout chamber by a partition wall, and the wind direction rectification is The chamber is divided into left and right halves by a partition wall in the longitudinal direction to correspond to the left and right sides of the thawing chamber, and a partition wall with a fan-shaped opening is provided between the damper chamber and the wind direction rectification chamber, and a partition wall is provided in the center of the damper chamber. A rotating shaft is installed in the longitudinal direction, and a sleeve to which sector-shaped blades that alternately open and close the openings of the partition wall are fixed is mounted on the rotating shaft, and the blades are fixed by rotating the rotating shaft by 90 degrees or more. 90 sleeves
A reversing damper characterized in that it is configured to alternately open and close an opening in a bulkhead by rotating twice.

(2) A spring is interposed on the partition wall side of the sleeve to which the blade is fixed, and a convex portion and a concave portion are formed on the opposite side end surface approximately half the circumference, and are connected by a taper and engaged with the spring. A boss with protrusions and recesses is also provided on the rotating shaft, and a sealing plate made of rubber or the like is attached facing the partition wall of the blade, so that the opening of the partition wall is sealed as the blade rotates. The inverted Dantzmer described in claim (1) of the utility model registration claim characterized in that
