Abstract: PROBLEM TO BE SOLVED: To perform hihgly efficient operation control by a method wherein the number of revolutions of a compressor is controlled by a temperature differ ence between the temperature of a cooler and a set temperature. SOLUTION: A refrigerating chamber temperature is detected by a refrigerating chamber temperature detecting means 21, a set temperature is detected by a refrigerating chamber temperature setting means, and on/off of a compressor 17 are determined by a temperature difference therebetween. The temperature of a cooler 13 is detected by a cooler temperature detecting means 42 and the number of revolutions of a compressor 17 is decided by a number of revolutions computing means 25 by means of a temperature difference between a cooler temperature and a cooler set temperature. By controlling the number of revolutions of the compressor by an inverter circuit 26, a cooler temperature is not reduced more than necessary to cool a chamber, and high-efficient operation is performed.

Abstract: PROBLEM TO BE SOLVED: To maintain freshness of a food by a method wherein the number of revolutions of a refrigerator fan is reduced to a minimum and the increase of a refrigerator temperature is suppressed to a minimum, in operation right after defrosting of a refrigerator on which an inverter is mounted. SOLUTION: By detecting a defrosting completion signal from a defrosting completion detecting means 10, an output is fed to a number of revolutions of fan correcting means 12. The minimum number of revolutions is selected in getting priority over the number of revolutions decided by a temperature difference between a refrigerator temperature and a set temperature. Cooling air has the efficiency of heat-exchange being improved in such a away that the number of revolutions of a refrigerator fan 8 is suppressed by being delayed by a time in which operation of a timer 13 is completed or temperature by a vaporiser temperature detecting means attains a given value and an airflow is reduced, and the cooling air is fed. Thereafter, the number of revolutions is increased to a value decided by a temperature difference between the refrigerator temperature and the set temperature and a cooling airflow is increased.

Abstract: PURPOSE:To prevent a defect in operation due to frosting, icing, etc., at a movable part in a storage room and improve the stability of vending operation by performing both or either of a door and an in-box conveyance device in idling operation irrelevantly to vending operation. CONSTITUTION:The door 16 or in-box conveyance device 17 is placed in idling operation through a timer 66 and an in-box temperature sensor 67 irrelevantly to whether or not vending operation is carried out, when the possibility of vending is low, for example, in nighttime, one hour after defrosting is completed, at the time of recooling operation at the time of a power failure, maintenance, etc., or when the in-box temperature nearly reaches 0 deg., namely, when an idling operation control means 68 decides that set conditions are met. Therefore, the development of local frosting and icing can be prevented at the rotary and slide parts of the in-box conveyance device 17 and the seal part of the door 16. In this idling operation, steps of vending are given priority, so even when the idling operation and vending operation are performed simultaneously, the cycle time of the vending operation never becomes long.

Abstract: PURPOSE:To make a shock caused by a drop of ice constant, to sanitarily hold the inside of a machine, and also, to prevent the periphery from being stained by making a throwing-in distance to the surface of an extracted liquid of ice constant even in the case of different cup size and supplying ice. CONSTITUTION:When a selecting signal is inputted by a cup size selecting switch, ice 24 of the quantity corresponding to each cup size is carried out by an ice supply means 14 and held temporarily in a bucket 13. Thereafter, by a sales signal, a motor 21 rotates to a position corresponding to cup size and by a crank 22, an ice throwing-in means 20 moves downward and moves to a prescribed position corresponding to cup size and becomes a holding state. In such a state, supply of a cup 23 is started from a cup take-out means. Thereafter, the cup 23 is carried by a cup carrying means and in the prescribed position, a raw material of the quantity corresponding to each cup size is thrown in by a raw material throwing-in means.

Abstract: PURPOSE:To enable water to be easily fed even when a device is set in a state that there is no space at an upper section, by arranging a cylindrical guide extended from the external wall of a hot-water storage tank, and an attachable or removable lever to be tightly fitted on the channel of a feed water receiving cylinder section from the long slot of the guide. CONSTITUTION:A hot water storage tank 5, a cylindrical guide 16 extended from a tank external-wall, and an attachable or removable lever 19 to be tightly fitted on the channel 15 of the cylinder section 14 of a feed water receiver 13 from the slot 17 of the guide 16, are arranged. The feed water receiver 13 is rotatably supported with the sliding surfaces of the outer peripheral surface of the cylinder section 14 and the inner peripheral surface of the guide 16, and so, at the time of feeding water, by moving the feed water receiver 13 rotationally, it can be led forward further from the front surface of a machine main body, and feed water working can be certainly performed without being disturbed, and after the completion of feed water, by moving the receiver 3 rotationally, it can be contained above the tank, and can be contained without being projected from the front surface. Besides, in the case of washing, by moving the attachable or removable lever 19 rotationally, the fitting of the channel of the cylinder section on the lever 19 is cancelled, and the feed water receiver can easily be removed.

Abstract: PURPOSE:To suppress the use current capacity to the current capacity of a power source outlet by detecting the value of current flowing in a plug by the signal from a current sensor, and in case that this current value in larger than the reference current value, stopping the current application to a tea feeder. CONSTITUTION:In case of having used a coffee server 2 when operating a refrigerator 3 and a tea feeder 1, the current flowing in a plug 7 exceeds the current capacity 15A of the power source outlet inside an office. The inverted input terminal voltage of a comparator 15 becomes higher than the reference voltage being the noninverted input terminal voltage, and the output of the comparator 15 becomes L. A transistor TR1 is turned on, and the normally close contact 17 of a relay 18 opens. Accordingly, the heater 21 of the tea feeder 1 is turned off regardless of ON/OFF of a thermostat 22, so the current flowing in the plug 7 can be suppressed below the electric capacity 15A of a power source outlet.
