Abstract
A walk-in freezing cabinet (13) is provided with a door locking handle assembly (10) and an in-cabinet unlocking mechanism. A worker can open a door (3) of the cabinet (13) from either the exterior or the interior of the cabinet (13) by either pulling upon and lifting an operating handle (14) of the assembly (10) or by depressing an in-cabinet push rod (1) of the mechanism. When moisture in the external air enters a receiving hole (9) of the door (3) frost is formed therein and contacts the push rod (1) which is slidably received in the receiving hole (9) of the door (3) to extend into the interior of the cabinet (13) resulting in locking of the in-cabinet push rod (1) with the frost. Such frost formation is prevented by a sealing member (7) disposed adjacent to the in-cabinet push rod (1) in the receiving hole (9).
