    Abstract: PURPOSE:To prevent a temperature rise in a refrigerator after a short time defrosting operation by providing a control unit for performing a forced cooling operation for a fixed time after defrosting operation regardless of a detected temperature by a temperature detector. CONSTITUTION:In normal operation, a defrosting timer 21 of a defrosting control unit 19 integrates signals from a comparator 15, and at the completion of integration after a fix time, a compressor 9 and a blower 7 are operated for a given time to perform a forced precooling operation so as to prevent a temperature rise in a freezing room 6 in defrosting. After a given time has passed, the compressor 9 and blower 7 are turned off, and a defrosting heater 11 is turned on to start defrosting. After that, a bimetal 20 detects finish of defrosting, and the defrosting heater 11 is turned off. The integrating time of the defrosting timer 21 is reset, a transistor 22 is turned off, and an armature of relay 13 is moved from 13b to 13a. At the same time, an output-terminal 01 outputs H signal for a given time, causing relay 12 to be closed through a transistor 17 and a relay coil 18, and the compressor 9 and blower 7 to be operated by force to keep a temperature rise in a refrigerator to the minimum. Then after a given time has passed, operation is returned to normal.

    Abstract: PURPOSE:To prevent a space above an ice making pan from becoming humid upon starting ice making and prevent frosting on a partition plate above the ice making pan by a method wherein the inside of a thermocase communicates with an ice making corner through a communicating port and is communicates with a returning air passage through a penetrating port. CONSTITUTION:A thermocase 15 receives a temperature sensor 10, controlling the temperature of a freezing chamber, while the temperature sensor 10 is supported by a supporting fitting 15a. A communicating port 15b communicates with an ice making corner 8a with the inside of the thermocase 15 to detect the temperature of the freezing chamber 2. A penetrating port 15c communicates with the inside of the thermocase 15 with a freezing chamber returning air passage 14. According to this constitution, moisture above the ice making pan 8 enters into the thermocase 15 through the communicating port 15b of the thermocase 15 upon starting ice making, then, the moisture is induced from the penetrating port 15c of the thermocase 15 and, therefore, the humidity above the ice making pan 8 is reduced whereby frosting on the partition plate 11 above the ice making pan 8 can be prevented.

    Abstract: PURPOSE:To improve the heat radiation efficiency of a radiation pipe and to facilitate a mounting work by a method wherein a double flange having a pipe groove is formed on the front opening edge of a cabinet, and after the radiation pipe coated with good thermal conductive hot melt is inserted in the pipe groove, it is secured by means of a reinforcing member. CONSTITUTION:A double flange 26 formed on the front opening edge of a cabi net 22 is formed by bending one beltform coat steel plate. In the double flange 26, an inner box insertion groove 31 and a pipe groove 32 are formed by a front flange 26a formed by bending side plates on both sides and atop plate 25 and a rear flange 26b continuously folded back to the rear with a slight distance therebetween. A radiation pipe 33 is inserted through the back flange 26b into the pipe groove 32, and is firmly secured in the pipe groove 32 by means of a reinforcing plate 34. Good thermal conductive hot melt being thermo plastic resin by which thermal conduction to the cabinet 22 is improved is coated on the surrounding part of the radiation pipe 33.

    Abstract: PURPOSE:To ensure vaporizing capacity of defrosting water without blocking dissipation of heat from a compressor and increasing the volume of a machine room, to improve reliability of a compressor, and to reduce a consumption power amount, by a method wherein a plurality of vent holes are formed in a boardlike porous member disposed facing a compressor. CONSTITUTION:Since vent holes 13-a are formed in a boardlike porous member 13 situated facing a compressor 11, the heat of a compressor 11 can be imparted directly on defrosting water sucked from a vaporizing pan 12, and the defrosting water can be effectively vaporized from both surfaces of the porous member 13. Thereby, the sizes of the vaporizing pan 12 and the porous member 13 can be enoughly decreased, resulting in reduction of the size of a machine room 10. Further, since convection is prevented from being blocked, the compressor can be prevented from being heated to a high temperature, and an increase in a consumption power amount due to lowering of long term reliability and lowering of efficiency can be suppressed.

    Abstract: PURPOSE: To reduce noise and vibration at the time of starting without increasing the size of a motor by providing a first accumulator and a second accumulator arranged in a heat insulating material. CONSTITUTION: When a compressor 18 is stopped, refrigerant and oil 27 leak through the gap of a cylinder 18b, a piston 18c, or the like, at a mechanical section 18d to the low pressure side. The refrigerant flows through a return tube 25, a second accumulator 24 and a connecting tube 23 and then it is condensed sequentially by a cooler 21 and a first accumulator 22. The oil is stored only at the lower part of the return tube 25. At the time of restarting the compressor 18, liquid refrigerant is sucked instantaneously from the cooler 21 and the first accumulator 22 into the compressor 18 but only the gas refrigerant evaporated by the second accumulator 24 in a heat insulating material is sucked along with the oil 27 stored at the lower part of the return tube 25. Since the second accumulator 24 can be embedded in the heat insulating material above the machine room, lift to the compressor is increased and the oil can be prevented from storing in the first accumulator.
