Abstract: PROBLEM TO BE SOLVED: To provide a refrigerator having good responding performance when switching from a cooler for a freezing room to a cooler for a refrigerating room by compactly installing a refrigerant control device. SOLUTION: By providing a space 14 for gathering liquid at the lower part in the opposite direction of a valve driving part of a large volume, a refrigerant control device 5 can be installed compactly. When a valve is opened, gas refrigerant flows upward, a liquid refrigerant quickly moves upward by the shearing force generated by the flow velocity thereof, so that it is possible to provide a refrigerating system having good responding performance when switching from a cooler for a refrigerating room to a cooler for a freezing room.

Abstract: PURPOSE:To obtain a delicious teat whose taste and color are both strong, in which tea leaves are open enough even at the time of supplying tea of first decoction by providing a steaming control means for supplying new tea leaves to a tea strainer, and thereafter, electrifying a valve to the extent that the tea leaves become wet for a prescribed time, and supplying hot water. CONSTITUTION:When a tea strainer 7 returns completely to a correct position by a rotation of a motor, a first switch 12 is turned on, and H is inputted to an input terminal (b) of a microcomputer 29. L is outputted to an output terminal (f), a motor is turned off, the strainer 7 is stopped in a correct position, new tea leaves are supplied to the tea strainer 7 from a tea canister 9, and an ON integrating time of a hot water supply valve is reset. Subsequently, H is outputted to an output terminal (e) of the microcomputer 29, and the hot water supply valve 5 is turned on. Next, whether the turn-on time of the hot water supply valve 5 exceeds a prescribed time T2 or not is checked. This prescribed time is the time for only supplying hot water to the extent that the tea leaves in the tea strainer 7 become wet. When the prescribed time T2 elapses, the hot water valve 5 is turned off, and the tea leaves subjected to hot water supply to the extent that they become wet are opened enough before supplying of first decoction.

Abstract: PURPOSE:To positively prevent the arching and the accumulation of the tea-leaves, and in addition, to contrive the simplification of the mechanism concerned by providing a hopper shaft, a vibration plate inserted being made freely rotatable with the hopper shaft working as the pivot of the rotation, and a worm-shaped auger which conveys tea-leaves by the motion of its twisting, all of the above-mentioned parts being housed in the tea leaves feed hopper. CONSTITUTION:By bringing in contact the periphery of the top-end part 27 of the screw-thread of an auger 24 and one end of vibration plate 14, where the auger 24 rotates, following said rotation, the end of the vibration plate 14 is pushed upward caused by the rubbing action against the rotating screw in the manner of rubbing on the periphery of the top-end 27 of the screw thread. Because of this action, the tea-leaves stored in the feed-hopper is subjected to stirring in the form of being pushed up once. As the rotation of the auger proceeds and reaches a certain point where the vibration plate 14 separates from the engagement and rubbing state does not exist with the periphery of the top-end 27 of the screw thread, tea-leaves covering the distance of approximately one pitch which is equal to a distance between two adjacent screw-threads, that is the distance to the top-end 27 of this side which follows being twisted, fall under the weight of tea-leaves. At this time, the shock of the falling tea-leaves weight applies on the vibration plate 14, resulting in that the tea-leaves which have been pushed up in the feed hopper so far are prevented from causing arching and accumulating because their falling shock are applied thereon.

Abstract: PURPOSE:To make it possible to carry out an efficient operation of the supplier by providing a sub-tank within a main tank, heating a heat medium within the sub-tank up to a supply hot water utilizable temperature by a compressor of a heat pump device thereby to shift the heat medium to the main tank. CONSTITUTION:A heat medium within a sub-tank 29 passes through a pump 34 by the circulating operation of the pump 34 and is circulated to a heat medium inlet 36 at the lower part of the sub-tank from a condenser 23. During this time, the temperature of the heat medium within the sub-tank 29 which has been heated within the condenser 23 gradually rises up. When the temperature of the heat medium reaches a supply hot water utilizable temperature, a switching valve 31 is closed by means of a temperature sensor 37. Then, the discharge pressure of the pump 34 is applied to the sub-tank 29 to produce a pressure difference between the sub-tank 29 and a main tank 28, and a check valve 40 is opened, the heat medium whose temperature has been raised flows into the upper part of the main tank 28. The heat medium of a low temperature passes through the condenser 23 from the lower part and flows into the lower part of the sub-tank 23. Accordingly, the heat medium of the supply hot water utilizable temperature is obtained in a short time and further the condensing pressure undergoes a gradual change in accordance with the temperature of the heat medium.

Abstract: PROBLEM TO BE SOLVED: To obtain a refrigerator using combustible refrigerant in which damage of low pressure refrigerant piping and leakage of refrigerant can be detected easily. SOLUTION: Refrigerating machine oil of a compressor 1 is mixed with an oxygen detecting agent changing hue upon reaction to oxygen and a pipe 20 for visualizing flow of internal fluid is provided as a part of piping of refrigeration cycle. When low pressure refrigerant piping is damaged, outdoor air flows into the piping because the inner pressure of the piping is lower than the atmospheric pressure. Since the oxygen detecting agent mixed into the refrigerating machine oil reacts on the oxygen in the outdoor air to change the hue, an abnormality can be detected easily in the early stage.

Abstract: PROBLEM TO BE SOLVED: To improve a cooling efficiency and an ability to keep food fresh by elevating a humidity in a refrigerating chamber of a refrigerator which includes a freezing chamber and the refrigerating chamber. SOLUTION: A freezing refrigerator comprises a cooling system and a plurality of cooler fans A9a and B15 which cool respective rooms, wherein the cooling system is constructed such that one connecting line which connects a freezing chamber evaporator 7a with freezing chamber pressure reducing means and another connecting line which connects a refrigerating chamber evaporator 11, refrigerating chamber pressure reducing means and a closure valve with each other are branched off in parallel and are connected with a suction line, an ability controllable compressor 6a and a condenser 17 in series. Due to such a construction, it becomes possible to supply cool air to each room in a proper amount necessary for cooling the room so that an efficient cooling can be realized by restricting an influence to other rooms. Furthermore, in the refrigerating chamber 3, the ability controllable compressor 6a, the condenser 17, the closure valve and the cooler fan B15 are operated in response to an indoor condition by system control means so that a humidity can be elevated easily.
