Abstract: PROBLEM TO BE SOLVED: To relive the discontinuity of a refrigerant gas flow generated according to the opening and closing of a reed valve which opens and closes a suction hole, and also controls the vibration amplitude of the read valve. SOLUTION: A closed small chamber 9 is opened through a branch pipe in a pipe line 18 between a suction port 14 and a suction muffler 17. When a reed valve 15 is closed, gas is led into the closed chamber once and, when the reed valve 15 is opened again, the gas in the small chamber is made to flow out immediately so as to reduce the sucking delay and increase suction efficiency. Also a sound resonance energy determined by the specifications of the closed small chamber and the branch pipe is used so as to control the amplitude of the reed valve to increase the performance and efficiency.

Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent excess cooling of a cooler and enhance operability with higher efficiency even when a motor-driven damper is opened and closed. SOLUTION: Based on a freezer compartment setting temperature of a freezer compartment 8 predetermined with a freezer compartment setting means 23 where the rotational speed of a fan 14 which feeds air to a cooler 13 and the rotational speed of a compressor 17 determined with a rotational speed arithmetic operation means 25, the temperature of the cooler 13, which is lower than the setting temperature of the freezer compartment and capable of operating the compressor 17 with higher efficiency is set to a cooler differential temperature arithmetic operation means 37 with a cooler temperature setting means 36 as a cooler setting temperature. The differential temperature between the cooler temperature detected with a cooler temperature sensor 38 and a cooler setting temperature is computed with a cooler differential temperature arithmetic operation means 37 and the rotary speed 14 is controlled with a fan rotational speed arithmetic operation means 39 based on the differential temperature, thereby maintaining the cooler 13 near the cooler setting temperature.

Abstract: PROBLEM TO BE SOLVED: To reduce the thermal load of a compressor by so controlling to vary the number of revolutions of a fan motor for cooling the compressor when the temperature of a discharge tube rises. SOLUTION: The indoor temperature input to control means 12 is compared with a set temperature, and the number of revolutions of a fan motor for cooling a compressor is decided. Then, the output of discharge tube temperature detecting means 11 is input by the input terminal 15 of the control means 12. Whether the discharge tube temperature is a predetermined value or not is judged, and if it is the predetermined value or more, the number of revolutions of the motor for cooling the compressor is altered, while if it is less than the predetermined value, the alteration of the number of revolutions of the motor for cooling the compressor is released. Then, the decided number of revolutions of the motor for cooling the compressor is output, and then whether the defrosting operation is started or not is judged. If the defrosting operation is started, the output of a compressor rotation command from the output terminal 01 is set to '0' rotation, and the rotation command of the motor for cooling the compressor from the output terminal 01 is set to '0' rotation. A relay 8 is turned ON to supply a current to a heater 9.

Abstract: PURPOSE:To simply and compactly carry articles stored in a stock to an electronic range without generating the slip or drop of food. CONSTITUTION:In an automatic food vending machine including an electronic range, a door 21 has a door latch 201 for holding the door 21 itself at a closed state on one side and a door hinge 208 on the other side and a door cam 209 having an internal cam 210, a con'rod 211 whose one end is engaged with the cam 21 and the other end is connected to a crank to be rotated by a motor and a spring 213 for exciting the con'rod 211 to the prescribed position of the cam 210 are arranged in the vicinity of the hinge 208. Since load is not almost applied at the initial stage of starting a door opening/closing mechanism, a motor with low torque can be used. Since inertia does not directly shock a link at the time of stopping the motor for opening/closing the door 21, food can be simply and compactly prevented from being slipped/dropped and the effect of practical use can be improved.

Abstract: PURPOSE:To shorten water boiling time in the rising operation after the supply of water by dividing water in a hot water storage tank by the zones to boil up the water in the zone concentratedly. CONSTITUTION:A zone wall 14 is provided free to insert to divide a hot water storage tank 7 along a guide 13 which is formed extending from an internal wall surface of the hot water storage tank 7. A heater 21 is arranged being biased to either of zones surrounded by the zone wall 14 and a wall surface of the hot water storage tank 7. A communicating part 18 is provided to conduct between the zones and a hot water supply pipe 19 is provided in the same zone of the heater 21 at a position separated from the communicating part 18 sandwiching the heater 21. In the additional boiling operation or the like after the supply of water, the zone wall intercepts a convectional motion of water in the hot water storage tank thereby making water within one zone concentratedly.

Abstract: PURPOSE:To feed a constant amount of tea at all times without decreasing an amount of hot water fed from a hot water feed valve even when a water level in a tank is lowered, in a water boiling device used for a tea feeder for feeding tea. CONSTITUTION:When a tea switch 30 is turned ON, a hot water feed control means 31 opens a hot water feed valve 18 for a specified time. When a time between a time at which a heater 16 is turned OFF by a second temperature deciding means 28 and a time at when the heater 16 is turned ON by a first temperature deciding means 27 is shorter than a given time, the ON time of the hot water feed valve 18 is corrected and increased by a hot water feed time correcting control means 32. A water boiling device comprises the hot water feed control means and the hot water feed time correcting control means.

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.
