Abstract: A refrigerator comprising a cabinet, a door configured to open and close an opening of the cabinet, and an outside air heat inductor arrangeable inside the door to extend toward the cabinet from a front portion of the door. The outside air heat inductor includes a first heat transfer path forming member configured to transfer outside air heat from outside the refrigerator toward a surface of the cabinet, and a second heat transfer path forming member arrangeable between the first heat transfer path forming member and an inside of the cabinet such that while the second heat transfer path forming member is arranged between the first heat transfer path forming member and the inside of the cabinet, the second heat transfer path forming member receives the outside air heat and prevents cold air within the cabinet from being transferred to the first heat transfer path forming member.

Abstract: A blower configured to circulate cold air inside a body of a refrigerator. The blower includes a casing, an impeller accommodated in the casing, and a support member configured to support the impeller against the casing. The impeller includes a disk-shaped base plate rotatably supported by the support member. The casing includes an inner circumferential surface extending so as to gradually move away from an outer circumference of the base plate toward a rotational direction of the impeller at a predetermined position around the outer circumference of the base plate, and a first case flow path between the inner circumferential surface and the outer circumference. An introduction port configured to introduce the cold air to a second case flow path branched from the first case flow path is formed on the inner circumferential surface of the casing.

Abstract: Disclosed is a refrigerator that facilitates access to each evaporator and improves maintenance performance. In the refrigerator, a different temperature of cold air cooled by each evaporator is brought into each cooling chamber with a different temperature range and different humidity range. The refrigerator includes a main refrigerator body including a machine room and a cooling chamber, an evaporator contained in the machine room, and a cooling unit detachably mounted in the machine room and including a compressor, a condenser, and an insulation member, wherein the cooling unit, while mounted in the machine room, has the insulation member tightly contact an inner wall of the machine room to form an insulation space, and the evaporator is contained in the insulation space.

Abstract: An infrared radiation detector is provided for receiving an infrared radiation emitted from a material being cooked placed in a cooking chamber in a microwave oven. The microwave oven is provided with a keyboard, a digital display and a microcomputer, such that when a temperature operation mode is set by entry from the keyboard the set temperature data is stored in a memory. In the temperature operation mode, the temperature of the material being cooked is detected in terms of a voltage associated with the output from the infrared radiation detector and a magnetron of the microwave oven is energized until the above described detected voltage becomes equal to the set temperature data and the magnetron is deenergized when both coincide with each other. In the temperature operation mode the temperature of the material being cooked is displayed by the digital display.
