リーチインシヨーケースの背面扉装置。 A rectangular parallelepiped box with an inner box inside the main case surrounded by insulating walls on five sides, a duct for cold air ventilation between the insulating walls and the inner box, and a cooler inside the duct. An air blower is installed to cool the inside of the refrigerator by circulating cold air while forming an air curtain in the opening that is commonly opened in the insulation wall and the inner box. In a reach-in case with a structure that has a door that can be opened and closed, an opening for product loading is provided in the insulation wall and inner box on the back of the main case, and the opening is equipped with a sliding insulation door that closes the insulation wall opening. Attach a sliding partition door that closes the opening of the inner box, create a duct for cold air ventilation between this insulated door and the partition door, slope the rail that receives each door in the direction in which the door closes, and It is characterized by providing a stopper that stops when the door is open so that the insulation door and the partition door stop when the door is open, and further releasing the stopper at the same time so that the insulation door and the partition door are closed in conjunction with each other. A rear door device for reach-in cases.
