Abstract: PROBLEM TO BE SOLVED: To enable the efficient cooling of a food storage chamber in which the food is stored and an ice-making chamber to make ice at the stable temperature by preventing the temperature rise in the chambers, and eliminating the supercooling. SOLUTION: An applied voltage determining means 53 to determine the voltage V to be applied to a first thermoelectric module 25 to cool chambers according to a temperature difference ΔT between the in-chamber temperature T and the preset temperature Tref so that the applied voltage is high when the temperature difference is large and the applied voltage is low when the temperature difference is small, and the applied voltage is set higher in an ice-making case as compared with a case where no ice is made, is provided, and the inside of the chambers is efficiently cooled at the stable temperature by setting the rise of the applied voltage in an ice-making case to be the voltage value obtained at a cooling surface of the first thermoelectric module 25 to cool the inside of the chambers with the heat absorption agreed with the heat radiation from the heat radiating surface of a second thermoelectric module for ice-making.

Abstract: PROBLEM TO BE SOLVED: To provide a method for charging liquid in a thermoelectrical module type cooling system capable of reducing mixture of air bubbles and charging cooling water. SOLUTION: This thermoelectrical module type cooling system is constructed such that a liquid suction port 34 between a thermal radiating heat exchanger 10 and a heat exchanging section 26a of a manifold is connected to a liquid tank 51. A pump 52 is connected in series to a suction port or a discharging port of a circulating pump 14b. The pump 52 is operated to suck up liquid from a liquid tank 51. Upon reaching of liquid to the discharging port of the pump 52, operation of the pump 52 is stopped and the liquid suction port 34 is closed and the pump 52 is removed so as to close a connecting port between the pump 52 and a circulating passage.

Abstract: PROBLEM TO BE SOLVED: To provide a thermoelectrical module cooling system having such a structure as one in which air bubbles circulating in a cooling water passage can be reduced as much as possible. SOLUTION: This thermoelectrical module type cooling system is constructed such that a position of a first circulating pump 14a of a thermal radiating cycle is arranged at a higher position than a first heat exchanging section 26a of a manifold 11 having a thermal radiating heat exchanger 10 and a thermoelectrical module. A position of a second circulating pump 14b of a heat absorbing cycle is arranged at a higher position than a cooling heat exchanger 20 and a second heat exchanging section 26b of the manifold 11. Suction sides of the first and second circulating pumps 14a, 14b are provided with air accumulating sections 37a, 37b, the included air bubbles are recovered and circulating air bubbles are reduced so as to improve a heat efficiency.

Abstract: PURPOSE:To prevent a tank from abnormally heated when hot water operation is done without water in a tank, CONSTITUTION:Temperature detection means 18 is provided in a tank, and when hot water operation is done with a heater 7, the temperature detector means 18 controls on and off of the heater 7. There is further provided a controller which interrupts, when there are continued successively by a predetermined number of times cycles where the time of one cycle of the on-off cycles is less than a predetermined time, power supply to the heater 7 thereafter.

Abstract: PURPOSE:To provide the title device which allows a shelf to shrink by a method wherein when the shelf is held up and turned one of revolving shafts of a back shelf rotates on a support of a bearing part surrounding the periphery, and the other on changed support by the bottom of shelf rail positioned behind the revolving shaft, and a flange piece, thus the whole shelf is inclined parallel to a rounded back wall. CONSTITUTION:Revolving shafts 18 are protruded from both sides of a back shelf 15. One of them is fitted into a 1st bearing part of a shelf receiving rail, and the other is engaged with a 1st bearing part 27 of a shelf receiving rail 21 and they are faced to each other. A 2nd bearing part connected with a flange piece 30 is provided behind the 1st bearing part 27.
