    Abstract: PURPOSE:To improve lubricating operation of a machine part by locating a loop-form conduit in a level below an oil level in a refrigerator and returning refrigerating machine oil to a refrigerant through a closed loop, in a horizontal type rotary compressor to contain a machine part, driven by a motor, in an outer shell sealing a refrigerant and refrigerating machine oil. CONSTITUTION:A horizontal type rotary compressor 1 the interior of which is held at a high pressure performs eccentric rotation of a piston 5, contained in a cylinder 6, through the working of a motor. Through eccentric rotation of the piston, a refrigerant compressed in the cylinder 6 is discharged from a delivery cover 7 and delivered to the high pressure side (h) of a refrigerating cycle. Through rotation of a shaft 2 with the aid of the motor, mixture oil 9 of a refrigerant and refrigerating machine oil is sucked through a feed oil pipe 8 and fed to each slide part. In this case, a condensing part 15 of a loop- form conduit 13 is heat-exchangeably disposed to the back, not show, of, for example, a refrigerator, and the inlet part and the outlet part of the conduit 13 are arranged to the motor chamber side of the compressor 1. This constitution circulates a refrigerant so as to liquefy the refrigerant by means of the condensing part 15.

    Abstract: PURPOSE:To keep the inside of a storage box at a proper humidity to allow a long period storage of vegetables free from dew drops on the inside surface of the box by permeating steam over saturation humidity which is emitted from stored vegetables in the box due to transpiration function and respiration function through a moisture permeable film of a lid of the box. CONSTITUTION:A storage box 7 is approximately sealed by a lid 10 so that cold air does not directly penetrate into the box, and the inside of the box 7 is kept high humid due to steam transpirated from stored vegetables 17. Steam over saturation humidity produced in the inside of the box is gradually permeated into a cold air convection path 9 in which low humid cold air flows through a moisture permeable film 13 on the surface of the lid 10 of the box. Therefore, the inside of the box 7 is free from dew drops, causing no damage to the vegetables 17 by water drops or being in contact with water, and allowing the vegetables 17 to be kept fresh for a long period without drying or withering. Further, a wide opening of the lid 10 is convenient for putting in and taking out the vegetables.

    Abstract: PURPOSE:To provide a refrigerator with a draw-out type door which can be used conveniently by providing a movable rail supported by a fixed rail on a side wall of a storage room and further providing a hinge connecting the door for opening the storage room with the movable rail. CONSTITUTION:If a pull 32a of a draw-out type door 32 is pulled to release a locking body 41 from a protrusion 40, the door pivots on a hinge 38 so as to open a storage room 31. Under this condition, items can be placed on a receiving plate 34 or can be taken out therefrom. When the foor is pulled furthermore, the plate 34 is drawn out of the room 31, being guided by a fixed rail 33 and a movable rail 39. As a result, the storing section of the plate 34 is opened toward the outside, so that items of various kinds can be easily stored and taken out. When the door is opened, the receiving plate can be drawn out, so that items can be easily stored in the storing room 31 and taken out, with the result that a refrigerator which can be used conveniently is provided.

    Abstract: PURPOSE: To interrupt a high frequency generating circuit when the door of a refrigerating room is opened even upon occurrence of abnormality by comprising a refrigerator of a defrosting room disposed in a refrigerating room, a high frequency generator disposed on the outside of the refrigerating room, and a switch disposed at the door part of refrigerating room and interlocked with opening/closing of the door to open/close a contact. CONSTITUTION: A high frequency generating circuit 23 is connected through the (b) contact of a refrigerator door switch with a power supply 9 and if a defrost switch 22 is turned on when a refrigerator door 2d is closed, power us supplied to a high frequency generator 20 through a high voltage transformer 19 to generate high frequency wave. It is introduced through a waveguide 6 to a defrost room 4 and chilled foods therein are irradiated with high frequency wave and defrosted. When a refrigeration room door 2a is opened, contact of a refrigeration room door switch 16 is turned to normal open side (a) to interrupt the circuit 23 thus stopping defrost operation. According to the arrangement, the circuit 23 can be interrupted upon opening the door 2a even when the contact of door switch 21 is fused.
