Abstract: PROBLEM TO BE SOLVED: To inexpensively, accurately and quickly pour hot water in accordance with drink temperature that is desired by a user by reheating hot water, which is kept warm and heated up to a selected drink temperature at the time of sales. SOLUTION: A drink temperature selecting means 4 has 'slightly hot' and 'tepid' switches and selects five stage drink temperatures through the number of operations of each switch. When the switches do not operate, it is a standard temperature setting that is previously defined. A temperature value that is selected through the means 4 and a to water tank temperature detecting means 12 that is attached to a hot water tank are inputted to a temperature control operating means 11 and decides feeding time of an inducing heat nit 2. During energizaion, pouring hot water temperature acquired by a pouring hot water temperature detecting means 13 that is installed near a pouring hot water port of the unit 2 is sequentially fed back to check that it becomes a desired temperature, and the feeding time of the unit 2 is corrected.

Abstract: PROBLEM TO BE SOLVED: To provide a temperature control device capable of controlling a temperature of food without replacing a temperature sensor even if a food to be stored is changed. SOLUTION: There are provided a cooling means 3 for cooling an inside part of a refrigerator; a temperature sensing means 2 for sensing a temperature of air near food stored in the refrigerator; a food specifying means 4 for specifying a food to be stored in the refrigerator; a storage timer 7 for measuring an elapsing time elapsed after storing of the food; and a food temperature estimating means 5 for estimating a temperature of food on the basis of a thermal property of the food stored in the refrigerator. Then, since the cooling means 3 is controlled by the cooling control means 9 in such a way that a food temperature estimating value of the food temperature estimating means 5 may become a predetermined value, a food temperature can be efficiently controlled without replacing the temperature sensor every time the food stored in the refrigerator is changed.

Abstract: PROBLEM TO BE SOLVED: To provide a food inventory control device which is simple in operation and available relatively at a low cost. SOLUTION: A food image processing means 1 takes in only a food image. When the door of a refrigerator-freezer is opened and closed in a succeeding specified time, a store indication means 15 determines that foods are stored in a compartment of the door and directs the storage. Based on the direction, a timer means 32 starts the elapsed time from the store point of time as an inventory period. An inventory information memory means 21 stores the name of a compartment, a food image and the inventory period as food information. A take-out indication means 18, when the image of the food is taken in a specified time after the opening/closing of the door is detected, selects the take-out food based on the features of the image by a take-out food selection means 24. In this case, it is determined that the food is taken out and the food information is erased from the inventory information memory means 1 by an inventory information erase means 29. The food information is displayed by the food information display means 22.

Abstract: PURPOSE:To realize power saving for a refrigerator by controlling the number of revolutions of a fan motor for a compressor in response to the number of revolution of the compressor and further eliminating an operation of the motor for the compressor when a compressor temperature is low and air supply is not required even during operating of the compressor. CONSTITUTION:A compressor 7 and a fan motor 8 for the compressor are controlled for the number of revolutions according to an output voltage of a step-up type rectifier 10. When an atmospheric temperature detected by atmospheric temperature detecting means 20 is low and an input current of the compressor 7 detected by current detecting means 14 is small, it is not necessary to cool the compressor 7, and hence the motor 8 for the compressor is not operated even during operating of the compressor. Thus, unnecessary air supply to the compressor 7 can be eliminated.
