    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 remove firmly chlorine elements out of water supply water and to provide hot water most suitable for tea by providing a temperature detector, a boiling detector and a heater driving means which carries out warmth retaining control and boiling control and puts the boiling control prior to the warmth keeping control. CONSTITUTION:A controller 16 is provided with a first reference temperature deciding means 39 for receiving temperature signal of a temperature detector 12 and comparing it with a first reference temperature signal and a second temperature deciding means 40 for comparing the temperature signal with a second reference temperature signal which is lower than the first reference temperature signal. The controller 16 is further provided with a heater driving means which turns a heater 3 ON when a temperature signal is lower than the second reference temperature signal in the second temperature deciding means 40 and makes boiling control by which the heater 3 is turned OFF if a prescribed time period elapses after input of boiling signal of the boiling detector 3 and priority control by which the boiling control is put prior to warmth retaining control. By this, hot water is boiled long enough to remove firmly chlorine elements out of water supply water, whereby hot water most suitable for tea without smell can be supplied. If the boiling time is set to be 3 minutes, the hot water is never overboiled, whereby nice tea can always be served.

    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 obtain a tea feeder at a low cost by providing a dual-purpose valve for a tea feed valve and a hot water feed valve. CONSTITUTION:A control device 15 is constituted of a tea feed control means 17 and a hot water feed control means 19. When a first switch 13 is turned on and then a tea switch 16 is turned on, a hot water feed valve 6 is excited, and hot water is fed to a tea strainer 8 to feed tea. When a second switch 14 is turned on and then the tea switch 16 is turned on, a motor 12 is excited to positively rotate the tea strainer 8, the motor 12 is stopped by the on-signal of the first switch 13, tea leaves are fed to the tea strainer 8, the hot water feed valve 6 is excited, and hot water is fed to the tea strainer 8 to feed tea. When the first switch 13 is turned on and then a hot water switch 18 is turned on, the hot water feed control means 19 excites the motor 12 to reverse the tea strainer 8, the motor 12 is stopped by the on-signal of the second switch 14, and the hot water feed valve 6 is excited to feed hot water. When the second switch 14 is turned on and then the hot water switch 18 is turned on, the hot water feed valve 6 is excited to feed hot water.

    Abstract: PURPOSE:To prevent the generation of harmful gas giving bad influence on a preserved material, by circulating air from a storage chamber to a combustion furnace with a blower, adsorbing excess carbon dioxide gas from a gas generated in the combustion furnace with an adsorbent, detecting the temperature of the combustion furnace and controlling the temperature with a controller. CONSTITUTION:A storage chamber 1 for a perishable material is connected with a carbon dioxide gas generator 8 to fill the chamber with CO2 and a CO2-adsorption apparatus 9 to adsorb and remove excess CO2 in the combustion gas. An alarm lamp 54 is lighted by a controller 52 according to the signal transmitted from a temperature detector 51 via a temperature regulator 53. An electric lock 57 of the exterior door 56 of the storage chamber 55 containing a combustion furnace 12 is also energized by the controller.
