Abstract: PURPOSE:To obtain a thermostat having a large difference between the temperature of the ON/OFF operation by fitting an auxiliary adjusting screw to a plate spring fixed to a lever and a frame so as to abut on the plate spring. CONSTITUTION:When the atmospheric temperature rises, displacement of a power element 1 is increased in response to the temperature to try to turn a lever 4. A coil spring 5, to which a constant tensile force is applied by an adjusting screw 6 previously to the direction for denying the power of the power element 1, is locked with the lever 4, and these force is balanced, and while the lever 4 is turned. When the lever 4 is turned at some degree, a plate spring 9 fixed to the lever 4 abuts on an auxiliary adjusting screw 10, and the plate spring 9 is bent. Temperature for turning a switch 3 ON is adjusted by adjusting the screw 10. When the temperature is lowered, the lever 4 is turned reversely, and the plate spring 9 is separated from the screw 10 to turn the switch 3 OFF. Consequently, a thermostat having a large difference between the temperature of the ON/OFF operation.

Abstract: PURPOSE:To make a cam face small-sized while reducing the width size of an appliance frame by making appliance frame tongue-shaped part to closely contact with the part of the cam face provided with ring-shaped groove so as to become a stopper. CONSTITUTION:The round axis part 104a of an adjusting axis 104 is projecting toward the outside of an appliance frame 101, while a flat part 104b is housed so that a tongue-shaped part 103 bent toward the inside of the base 102c of the appliance frame 101 may be positioned inside the ring-shaped groove of the cam flat part 104b. When the adjusting axis 104 is rotated, an arm 107 oscillates by displacement of the cam flat part 104b to change tension of a bias spring engaged with the arm 107 and generate an output change to a switch part for changing a set temperature. Here, when any part 105 not provided with the ring-shaped groove 106 of the cam flat part 104b of the adjusting axis 104 comes in close contact with the tongue-shaped part 103 of the appliance frame 101, the adjusting axis 104 can not rotate for being used as a stopper of the adjusting axis 104. Thereby, a small-sized thermostat can be obtained while improving the inside effective capacitance rate of a refrigerator.

Abstract: PURPOSE:To permit the perfect stopping of the flow of cold air with a simple structure by a method wherein a rotor, rotated in a housing so as to open and/or close one set or more than two sets of cold air outflow ports and the inflow port of cold air, is provided and the rotor is operated so as to be separated from the openings of the inflow port and the outflow ports when the position of the rotor is being changed while the rotor closes the selected openings perfectly after the position of the rotor is changed. CONSTITUTION:When a motor 7 is rotated, a rotor 5, connected mechanically to the motor 7, is rotated and the projected part 5a of the rotor rides on a rib 4q at the center of a housing whereby the flap section 5b of the rotor is separated from the openings 4a, 4b, 4c of a housing. When the position of the rotor 5 is changed to a next opening, the projected part 5a of the rotor enters into notches 4d, 4e, 4f of the central rib of the housing, which are corresponding to the openings 4a, 4b, 4c, and the flap section 5b of the rotor is contacted perfectly and closely with the openings 4a, 4b, 4c of the housing. According to this method, the rotor can be separated from the openings of the housing when the rotor is rotated while the rotor can seal the openings of the housing perfectly when the rotor is stopped after selecting the opening to be closed.
