Abstract: PURPOSE:To obtain a door supporting device, in which the sliding of a boss part is smooth and simple in mounting works, by a method wherein the door supporting device is constituted of two guides, guiding boss parts projected from both side surfaces of a door covering the front surface of a partitioned chamber, and a door supporting plate, having an introducing groove for guiding to the rear part of the partitioned chamber, while an elastic retaining piece for engaging the door with the guide units is provided. CONSTITUTION:A door 6 is inserted into a partial chamber under a condition that the door is slanted toward the direction of depth of the chamber, then, boss units 13a, 13b of a door 6 are inserted at first into guide rail units 14a, 14b of a middle partitioning units. Then, the other boss units 13a, 13b of the door 6 are guided into rear introducing grooves 17a, 17b of the door supporting plate 10 and the door 6 is pivoted forward, then, the lower side boss unit 13b of the door 6 pushes an elastic retaining piece 18 downward and rides over it whereby it is engaged with the guide rail unit 14a of up-and-down direction. When a vessel 5 is pulled out to this side, the rise-up sections 15 of side surfaces of the vessel 5 push up the door 6 and the door 6 slides along the guide rail units 14a, 14b whereby the opening of the chamber is opened. When the vessel 5 is received, the door 6 is closed by itself by the gravity of the same.

Abstract: PROBLEM TO BE SOLVED: To eliminate the leakage of drain to circumference by a method wherein a heat exchanger is arranged above a drain receiving pan so as to be neighbored thereto and the lower part of a porous member is buried into the drain receiving pan while the drain, recovered into the drain receiving pan, is evaporated by heat radiated from the heat exchanger. SOLUTION: A fan 22 is attached to the upper part of a heat exchanger 14 and a drain receiving pan 44 is arranged below the heat exchanger 14 while the lower part of a soft and porous member 52, such as sponge or the like, is buried into the drain receiving pan 44 and the upper part of the same is extended upward under a condition that the upper part of the same is contacted with the side surface of the heat exchanger 14. According to such a constitution, drain, recovered into the drain receiving pan 44, is evaporated by the radiated heat of the heat radiating side heat exchanger 14, which is contacted with the porous member 52, and is discharged to the outside from an upper grille 50 through a duct. According to this method, even when the amount of drain, recovered into the drain receiving pan 44, is much, the treatment of the drain can be effected surely whereby the leakage of the drain to surroundings can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To inject a liquid for refrigerant in a circulation channel easily and in a short time and also to enable injection of the liquid for refrigerant in a deaerated state by constructing a heat absorbing system unit by integrating a second circulating pump, a thermoelectric heat exchange block, a heat exchanger for cooling and a piping connecting these components. SOLUTION: An injection jig 98 is used for injection of a liquid for refrigerant and the injection is conducted by putting a pump body 91 in a non-driven state. The liquid for refrigerant is made to flow in the sequence of the pump main body 91 → a discharge port 94 → a thermoelectric heat exchange block →a heat exchanger for cooling → an inlet 93 by a force of pressure sending of a refrigerant supply pump 97 and returns to a chamber main body 92a. Then, the liquid for refrigerant overflows outside from a liquid overflow pipe 98c. By stopping the pressure sending of the refrigerant supply pump 97 at this time point, the liquid for refrigerant can be filled up in a second circulation system of a heat absorbing system unit. By disengaging the injection jig 98 from the chamber main body 92a and fitting it to a cap main body 92b thereafter, the operation of injection of the liquid for refrigerant is finished.

Abstract: PROBLEM TO BE SOLVED: To insert the fingertips easily and grip easily by providing a hand hole for transportation and installation from the interior side in an opening of an insulated box having a cooling compressor. SOLUTION: A cooling compressor 2 is incorporated in the outside surface of an insulated box 3 where an insulating material-made door 5 is formed in an opening 4 of the insulated box 3 while a hand hole 1 for transportation and installation is formed on the interior wall surface. This construction makes it possible to enhance the transportable ability, such as an easy inserting ability of the fingertips and an easy gripping ability. In addition to that, the hand hole 1 for transportation and installation is laid out on the upper part of the cooling compressor 1, which makes it possible to enhance gravity center balance when it is lifted up. Furthermore, the outer peripheral area of the transportation and installation hand hole 1 is filled up with the insulating material 6, which makes it possible to exert a reinforcing effect of the transportation and installation hand hole 1.
