摘要： PROBLEM TO BE SOLVED: To prevent a sewage from being contaminated by an acidic water by guiding moisture generated in a treating tank into a drain channel (sewerage) through a liquid cleaning device. SOLUTION: A high-temperature and high-humidity gas (mainly air accompanied by a smell and moisture) is conducted into the high temperature side (upstream) of a heat exchanger 72 passing through a gas intake pipe 76 from a crushing part 10 by actuating a gas circulator 75, and flows through a vent pipe. The heat of the moisture is transferred by heat exchange with air blown by an air blower 74 halfway through the heat exchanger 72, and is condensed into water. This water is drained to the liquid cleaning device 90 side passing through a drain pipe 92 from the low temperature side (downstream) of the heat exchanger 72. On the other hand, the air after the removal of moisture is returned to the interior of a treating tank 50 passing through an air return pipe 78 to absorb the internal moisture of the treating tank 50. The water dripping from the drain pipe 92 flows into a conditioning tank 94 and is neutralized by a weak alkali material. In addition, an organic matter is decomposed by a microbe 95 in a treating tank 96 into a harmless water, and is drained to the sewage side from a drain pipe 98.

摘要： PURPOSE:To prevent the generation of dew drops induced by local cooling of a vegetable vessel by installing a covered vegetable chamber vessel in a vegetable chamber so that a cooled air passage may be formed between said covered vegetable chamber vessel and its inner box and introducing cooled air available after a refrigerator chamber is cooled into the cooled air passage from a suction port in this side. CONSTITUTION:A top cover 14 of a vegetable chamber vessel 11 is cooled by the cooled air available after a refrigerating chamber 9 is cooled so that the chamber 11 may be cooled. The cooled air which is cooled the interior of a vegetable chamber 10 is entirely sucked up into a cooled air passage 17 where the cooled air in the rear side of the vegetable chamber 11 flows downward in a cooled air passage 16a. Since a vegetable opening section of a cooled air distribution duct 8 is located in the depth of the vegetable chamber 10, the cooled air whose temperature is equivalent to that available after the refrigerator is cooled, flows along the rear side wall and further flows downward. As the cooled air flows ahead of cooled air passages from 16b to 16d, the percentage of cooled air directly introduced from a cooler 5 is increased so that the cooled air may be mixed to a satisfactory extent, thereby producing an equalized temperature. Therefore, the cooled air introduced from the cooler is arranged not to come in direct contact with the vegetable chamber vessel 11, which makes it possible to cool the vegetable chamber 11 locally and prevent the generation of dew drops and freezing or the like in the chamber.

摘要： PURPOSE:To enable smooth and reliable opening and closing of a lateral biparting door through a low-cost mechanism and to prevent simultaneous release of engagement of fulcrums on both sides when a door is wide and large by a method wherein a resilient means by which 8 cam is restored to its original position when the cam is moved by means of an external force is brought into contact with a coupling lever. CONSTITUTION:Left and right cams 8 and 9 engaged with left and right binges 5 and 6 are intercoupled through two coupling levers of the one being an upper lever and the other being a lower lever in a manner to nip the cams in a sandwich shape. The coupling levers 10 and 11 are engaged with staged parts 24 and 25 mounted to the cams 8 and 9, and the coupling levers 10 and 11 and the cams 8 and 9 are formed so as to maintain a lock relation between the hinge pins 5, 6 and the cams 8, 9. Besides, a resilient means 26 to promptly return erroneous movement of the cams 8 and 9 to a regular position is provided. Thus, even when the positions of the cams 8 and 9 are erroneously moved, the cams are returned to a regular position in time for door closing operation. This constitution enables smooth and reliable opening and closing of a lateral biparting door through a low-cost mechanism, and prevents simultaneous release of engagement of left and right fulcrums even when a door is wide and large.

摘要： PURPOSE:To enhance operability by a construction wherein a second base member is extended from an intermediate part of a first base member to which a bellows member for supporting a blocking member is connected, a mount base is provided at an end part of the second base member, and an end part of the first base member is brought into contact with the end part of the second base member which is faced to the mount base. CONSTITUTION:A gasket 6 has a second base member 8b extended from an intermediate part of a first base member 8a to which a bellows member 7 for supporting a blocking member 9 is connected. A tongue-shaped mount base 10 to be fitted into a groove 5a in an extruded frame 5 is provided at an end part of the second base member 8b. An end part 8a' of the first base member 8a makes contact with a part opposite to the mount base 10. The base member 8a is inclined toward the blocking member 9, as indicated by broken lines, whereby a fin-shaped part 11 is inclined to minimize a gap which would be generated at an end edge part 11a of the fin-shaped part 11 when the part 11 is attracted onto a main body of a refrigerator.
