Abstract: PROBLEM TO BE SOLVED: To prevent flood damage to be caused by overflow by downsizing a machine room, and increasing the effective content volume, and accelerating the water evaporation in an evaporating pan, in a refrigerator which is equipped with a fan and the evaporating pan in the machine room. SOLUTION: This refrigerator is equipped with a machine room 3 where a compressor 5, an evaporating pan 6, and a fan 10 are installed, and a dust 2 which communicates with the machine room and is provided with a compressor 11 is installed, and the evaporating pan 6 is installed in the position near the suction side of the fan 10 and downstream of the compressor 11. Hereby, the machine room 3 can be downsized, and the effective content volume of the refrigerator can be increased, and storage property can be raised. Furthermore, the evaporating pan 6 can accelerate the evaporation of water, and can prevent the flood damage to be caused by overflow, thus high reliability can be obtained.

Abstract: PROBLEM TO BE SOLVED: To reduce the size by providing a connection tube for introducing defrost water, flowing over a main evaporation pan disposed closely to the upper part of a compressor, to an auxiliary evaporation pan disposed at the lower part of refrigerator body. SOLUTION: A main evaporation pan 11 disposed at the upper part of a compressor 5 is a container having open upper surface and defrost water is evaporated by the heat from a compressor and the cooling wind from a fan. An auxiliary evaporation pan 12 disposed at the lower part of a refrigerator body 9 in a suction duct 8 is a container having open upper surface and when the main evaporation pan 11 is filled with water, the defrost water flowing over the main evaporation pan 11 is introduced through a connecting tube 13 and evaporated by the cooling wind flowing through the suction duct 8. The main evaporation pan 11 has a capacity sufficient for storing the defrost water produced under normal operating conditions prevailing at least the majority of a year. Since the height of the main evaporation pan 11 can be decreased, the ineffective inner volume, i.e., the volume of machine room, can be decreased and the effective inner volume of a refrigerator can be increased.

Abstract: PROBLEM TO BE SOLVED: To remove dust and oil component adsorbing the dust while decomposing by providing a condenser having surface coated with an optical catalyst, and a light for irradiating the condenser with light. SOLUTION: A semiconductor other than titanium oxide may be employed as an optical catalyst but titanium oxide is most preferable in view point of non-water solubility, stability, or the like. When cooling air passes through a condenser 9, dust and oil component adsorbing the dust contained in the air adhere to the cooling air suction side of the condenser 9. The optical catalyst reacts on the light emitted from a light 10 to decompose dust adhering to the condenser 9 thus removing dust from the condenser 9. Since the oil component adsorbing the dust is decomposed, dust does not adhere easily to the condenser 9 and the dust which can not be decomposed through catalytic action can be removed easily, if any.

Abstract: PROBLEM TO BE SOLVED: To prevent invasion of unnecessary heat into a refrigerator by controlling a heating means in response to the output value of an indoor temperature sensor to maintain a partition plate surface temperature of the front surface of a partition wall for partitioning a storage chamber constant so that a dew point temperature vicinity temperature at arbitrary relative humidity calculated according to the output value of an atmospheric temperature sensor becomes constant. SOLUTION: A storage chamber is partitioned into four chambers of a cold storage chamber 30, first deep freezing chamber 31, second deep freezing chamber 32 and vegetable chamber 33, and the surface temperature of the partition plates 10, 11, 12 of the front surfaces of the partitioned partition walls are controlled by a heating means 17. The means 17 is controlled by a control means 18 by sending a signal from an atmospheric temperature sensing means 16 by sensing a temperature in the circumference of the refrigerator by an atmospheric temperature sensor 16 to the means 18, sending the signal of an indoor temperature sensing means 14 to the means 18 by sending the indoor temperature of the chamber 31 by an indoor temperature sensor 13, and the means 18 outputs output signals from the means 14 and 16 to the means 17. Thus, invasion of unnecessary heat into the refrigerator can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent lowering of compressor efficiency and wear of a sliding part by preventing the generation of local sliding and pinching at the sliding part of a piston and a cylinder even in case of the piston and a cylinder being machined and assembled with eccentricity and inclination in an oscillating compressor used for a refrigerating cycle or the like. SOLUTION: An oscillating compressor is composed of a shaft 13 axially connected to a piston 5, and a resonance spring 8 with its inner peripheral part fixed to a movable element 11 and with its outer peripheral part fixed to a fixed element 12. Accordingly, even in case of the piston 5 and a cylinder 4 being machined and assembled with eccentricity and inclination, the generation of local sliding and pinching at the sliding part of the piston 5 and cylinder 4 is prevented so as to prevent lowering of compressor efficiency and wear of the sliding part and to prevent excessive stress of the resonance spring 8, thereby obtaining high reliability.

Abstract: PROBLEM TO BE SOLVED: To prevent the contact and rubbing of a resonance spring even in case of the stroke quantity of a piston being increased so as to prevent the damage of the resonance spring and the generation of noise in an oscillating compressor used for a refrigerator, air conditioner, or the like. SOLUTION: An oscillating compressor is provided with a resonance spring 8a with an inner peripheral part 8b fixed to a movable element 5c and with an outer peripheral part 8c fixed to a fixed element 4c, an outer peripheral spacer 8d interposed at the outer peripheral part 8c of the resonance spring 8a, and an inner peripheral spacer 8e thicker in plate thickness than the outer peripheral spacer 8d and interposed at the inner peripheral part 8b of the resonance spring 8a. Accordingly, even in case of operating pressure or the like being changed to increase the stroke quantity of a piston 5, mutual rubbing of the resonance spring 8a is prevented without making the resonance spring 8a large-sized so as to be able to prevent the wear and damage of the resonance spring 8a and the generation of noise.

Abstract: PROBLEM TO BE SOLVED: To predict the generation of a liquid compression on the outer periphery of a roller piston from the surrounding temperature, by providing a suction pipe to communicate the inside of the lubricating oil and a suction pipe or a suction chamber, and an oil feeding valve between the opening in the lubricating oil of an oil feeding pipe and the opening on the suction pipe side by interlocking with a temperature detecting means. SOLUTION: When a starting time opening instruction output means 21 detects a temperature opening instruction and the starting of a compressor simultaneously, when the surrounding temperature is lowered and a temperature detecting means 17 outputs a temperature opening instruction, the starting time opening instruction of the starting time opening instruction output means 21 is detected and opened to an oil feeding valve 18. In this case, an oil feeding pipe 19 is to communicate the lubricating oil 11 at the lower part in an enclosed casing 1 and a suction pipe 16, and the lubricating oil 11 with a high pressure enters in a suction chamber in a cylinder 4 with a low pressure through the oil feeding pipe 19, passing through the suction pipe 16 and a suction passage 13, so as to lubricate the outer periphery of a roller piston 5. Consequently, an abrasion of the outer periphery of the roller piston owing to the shortage of lubricating oil 11 is prevented, and the efficiency and reliability is improved by making the oil feeding time adequate.
