摘要： PURPOSE:To simplify the constitution and allow the apparatus to operate smoothly by combining a cam in a specified form, pushing plate, and springs. CONSTITUTION:A Cam 3 having a door-opening silding groove 3a having an inclined plane on the side on which the distance to the center of revolution becomes shorter as the door opening angle increases, a door-closing sliding groove 3b having an inclined plane on which the distance to the center of revolution becomes shorter as the door is closed, and a communication groove 3c which communicates both grooves 3a and 3b is, with a door 2, pivotally supported on a pivot pin receiver 4. A pushing plate 7 having a contact part 7a which pressing-contacts the cam 3 is fitted freely operably in vertical and horizontal directions on the cold storage body 1 through a supporting shaft 8, receiving element 9, and springs 10 and 11. Thus, by the spring force of springs 10 and 11, the door 2 is opened and closed smoothly through the pushing plate 7 and the cam 3, and the quantity of constituting parts is reduced.

摘要： PURPOSE:To enhance defrosting efficiency and prevent hot air from flowing from a heater into a freezing chamber, by a construction wherein the heater in a duct on the upstream side of cold air is disposed at a predetermined distance from a fin located on the cold air inflow side of an evaporator. CONSTITUTION:A defrosting heater 3 is bent in a staggered form, and is inserted into a notched collars 1b of fins 1. Heaters 3c are disposed in the upstream side of cold air at a predetermined distance from the fin 1 located on the cold air inflow side. An evaporator 4 comprising the small fins 1 and a refrigerant pipe 2 is disposed in a duct 5 together with the heaters 3c. The duct 5 forms a cold air passage 6. The humidity of cold air passing through the evaporator 4 from the cold air inflow side to the outflow side is higher on the inflow side, but is lowered as the cold air flows toward the outflow side because water component in the cold air flow is absorbed on the fins at each stage to form frost. In such a distribution of frosting, the temperature of hot air from the heaters 3c is also higher on the cold air inflow side, but is lowered through cooling by the frost on the fins at each stage, so that the temperature distribution of the hot air from the heater is also proportional to the quantity of frost deposits.
