    Abstract: PURPOSE:To prevent frosting at the upper front of a dual tank type ice making plate by providing an opening on a partition above the dual tank type ice making plate to check the upper part of the dual tank type ice making plate from being moistened at the start of making ice. CONSTITUTION:An opening 14a is provided on a partition 14 above a dual tank type ice making plate 10. As a result, moisture above the dual tank type ice making plate 10 is released through the opening 14a on the partition 14 to reduce moisture being carried to the upper front 13 of the dual tank type ice making plate on a cool air from a discharge port 5b. This enables the prevention of frosting at the upper front 13 of the plate.

    Abstract: PURPOSE:To continuously cool lubricating oil through a syphon effect even during stoppage, by cooling the lubricating oil inside a lubricating pump with a thermosyphon tube utilizing a high temperature and pressure gas inside a compressor shell. CONSTITUTION:Since the inside of a shell 1' is filled up with refrigerant gas and thereby comes in a state of high temperature and pressure, a high temperature and pressure gas inside the shell 1' is introduced from an opening end 14a of a thermosyphon tube 14 being set up in a lubricating pump 12, and cooled with a radiator part 16 outside the shell, while the cooled liquefied drip is dropped to the pump 12 and lubricating oil inside the pump 12 is thus cooled. In addition, since the inside of the shell 1' is high pressure even in time of a compressor being stopped, circulation of the refrigerant gas takes place inside the thermosyphon tube 14 so that cooling of the lubricating oil 13 is performable.

    Abstract: PURPOSE:To obtain a refrigerator having no necessity of another heater and a low electric cost by improving clogging of a cooler and improving the heat exchanging efficiency of the cooler. CONSTITUTION:A cold storage chamber suction duct 11 is mounted at the side of a cooler 16, and an auxiliary suction duct 26 branched at the lower part of the duct 11 is disposed on the front surface of the cooler 16. A heater is arranged in the duct 11, and an auxiliary suction duct is arranged oppositely at the position of a glass tube heater 28.

    Abstract: PURPOSE:To prevent occurrence of so-called ''gas-column resonance'' or reduce the level of the same, by disposing a discharge gas pre-cooling radiator between a compressor and a base support, and thereby changing the length of the gas column. CONSTITUTION:A rotary comparessor 2 is fixed to a base 9 by the intermediary of dampers 10-1, 10-2, and a discharge gas pre-cooling radiator 6 is disposed in a space 11 formed between the rotary compressor 2 and the base 9. With such an arrangement, the space required for disposing damper members can be utilized as a space for installing the discharge pre-cooling radiator 6. Further, as for the gas-column resonance caused between the compressor 2 and the base 9, the length of the gas column can be changed by the presence of the pre-cooling radiator 6, so that noises produced by the compressor can be reduced.
