Abstract: PROBLEM TO BE SOLVED: To develop a refrigerator and an alcoholic drink storage device which can effectively utilize the surplus nighttime electric power and suppress the daytime power consumption. SOLUTION: A refrigerator is composed of a heat insulating box body 2 surrounded by heat insulating walls 8, a heat storage tank 3 which stores heat, a cooling device 5 which cools the tank 3, and a transmitting means 6 which transmits the cold heat in the tank 3 to the box body 2. The cooling device 5 operates when the electric power is surplus and the transmitting means 6 circulates a liquid heating medium through the heat storage tank 3. In addition, the transmitting means 6 works to adjust the temperature in the box body 2 to a prescribed value.

Abstract: PROBLEM TO BE SOLVED: To apply high rigidity to a shell, to make it hardly resonated, to damp its vibration, and to reduce its noise by providing irregular parts on the shell. SOLUTION: Many irregular parts are concentratedly provided at necessary positions on a shell. The irregular parts may be formed on the whole face of the shell, or they may be formed only at the positions where resonance is considered to occur easily and vibration damping and silencing are required for shape designing. The irregular parts may have a spherical shape, i.e., a dimple shape, a dish-like embossed shape, a ridge-like rib shape, or a lattice shape. The thickness of the recesses and projections of the shell is nearly equal to the thickness of the portion having no irregular parts, and the rigidity of the whole shell is increased and resonance rarely occurs due to the irregular parts, thus the plate thickness of the shell can be made thinner. The surface area of the shell is increased by the irregular parts, and its radiation effect is increased.

Abstract: PROBLEM TO BE SOLVED: To easily automate a shell assembling process by setting both width of a part element for composing a shell and one opening part of the other element to facilitate automatic insertion of the other opening part, and narrowing a clearance between overlapping parts by contracting one opening part from an outer peripheral side after inserting the other opening part. SOLUTION: A diameter of a container opening part 21a for housing a joint in a shell is slightly enlarged, and a clearance is formed between the container opening part 21a and a cover opening part 22a to facilitate automatic insertion of the cover opening part 22a. At the time of assembly, the container opening part 21a is contracted from its outer peripheral side after the cover opening part 22a is automatically inserted into the container opening part 21a by an automatic device, and a size(d) of a clearance 24' between overlapping parts is preferably set to 0.2 mm and less. A clearance is arranged between the cover opening part 22a and the container opening part 21a, and thereby, automatic insertion is facilitated, and the clearance between overlapping parts is uniformly narrowed. It is thus possible to reduce power supply at the time of welding.
