Abstract: PURPOSE:To prevent the leakage of foamed polyurethane insulating material and provide a door structure which presents little deformation and can be installed in a level position by inserting one of ribs disposed on the inside of the door cover into a channel-shaped groove in the door frame and engaging the other rib with the rib retaining part erected on the door frame. CONSTITUTION:A half-completed door is set in a foaming jig with the entire periphery of the door backing plate 7 being pressed against the bearing part 11d of the door frame 11, and then, foam polyurethane insulating material 8 is filled and foamed therein. By means of the bonding effect of the foamed polyurethane insulating material 8, the component parts are joined together to formed a structure of a door 2, wherein a gasket 6 is inserted to a groove 11c in the door frame 11. By securely fastening the door cover and the door frame with the ribs and hooks, the displacement or dislodging of the door cover can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent condensation or frost on the back surface of the lid of a vegetable case by arranging a shielding plate on the flow-in side of the return path of chilled air for a vegetable compartment and a ventilating path inside a thermally insulating partition walls. SOLUTION: The one side of the chilled air return path of a vegetable compartment formed inside the thermally insulated partition walls 16 forming a freezing compartment 4 and a vegetable compartment 6 partitioning them is connected to the refrigerating compartment 7, the other side is connected to the vegetable compartment 6 and the inlet hole 17a is arranged on the side of the vegetable compartment 6. The top board of the vegetable compartment 18 constituting the thermally insulated partition walls 16 is positioned vertical to the inlet hole 17a and forms a shielding board 18a extending upward from the lower surface 17b. The one side of ventilating path 19 formed inside the thermally insulating partition walls 16 is connected to the return path of the chilled air for the vegetable compartment 17 and the other side is connected to the flow-out hole 13a of the chilled air return path for the refrigerating compartment 13. When a blower 9 is stopped, the chilled air inside the refrigerating chamber 7 is stopped by the shielding plate 18a through the chilled air return path for the vegetable compartment 17 and flows out from the ventilating path 19 through the flow-out hole 13a to the backside of the vegetable case 14. Therefore, the lid 15 of the vegetable case 14 is not cooled preventing condensation and frost on the back surface.

Abstract: PURPOSE: To shorten the time for making ice by attaching a sensor in a space partitioned off in an ice-making vessel-holding part and providing a plurality of communicating holes by which the space with the sensor and the space to hold an ice-making vessel in the ice-making vessel-holding part communicate. CONSTITUTION: At the top side inside a freezing chamber there is provided an ice-making vessel-holding part 8, in which an ice-making vessel 10 containing water is placed. In a space 14 partitioned off in the ice-making vessel-holding part 8 a sensor 13 is attached and a plurality of communicating holes 15 by which the space 14 with the sensor and the space 9 to hold the ice-making vessel 10 in the ice-making vessel-holding part 8 communicate are provided. When the temperature of air rises, the sensor 13 detects the temperature through the communicating holes 15, the compressor and fan are actuated, and the chilled air blown by the fan is sent through a duct 11, discharged from a discharge hole and cools the water in the ice-making vessel 10. This method enables making ice in a short time.

Abstract: PURPOSE:To raise the temp. of the top plate of the emitting duct provided to the top surface of a low temp. chamber, to abolish a heater and to reduce power consumption by independently providing the emitting ducts guiding cold air to the low temp. chamber to both corners of the top surface of the low temp. chamber apart from the second partition wall. CONSTITUTION:The fourth emitting duct 22 is provided to the back surface of a low temp. chamber 5 and one end thereof is connected to the third emitting duct 15 and the other two ends thereof are opened to both deep corners of the top surface of the low temp. chamber 5. The fifth emitting duct 23 is connected to the fourth emitting duct 22 and forwardly extend from the interior of both corners of the top surface of the low temp. chamber 5. The fifth emitting duct 23 is formed from an insulating material 24 provided with a plurality of emitting orifices 23a. The cover 25 becoming a part of the top surface of the low temp. chamber 5 is provided so as to cover the heat insulating material 24 and the engaging part 25 of the cover 25 is mounted to the side wall 26 of the low temp. chamber 5 in a contact state. By this constitution, even when the cover 25 is cold by the cold air in the fifth emitting duct 23 through the heat insulating material 24, the difference between the temp. of the cover 25 itself and that of the low temp. chamber 5 is eliminated.
