摘要： PURPOSE:To enable a rapid stopping of supplying of electrical power to be carried out in the case that some abnormal states such as an over-load and a locked state and the like are produced in a capacitor induction electric motor for use in driving a fan. CONSTITUTION:A relay coil 19 for use in sensing an inter-terminal voltage of an auxiliary winding 17, for example, in the auxiliary winding 17 or a capacitor 18 of a capacitor induction electric motor 14 is provided. As the inter- terminal voltage of the auxiliary winding 17 is lowered than a value of range of application of a fan 21, a supplying of electricity for the electric motor 14 is stopped with a relay switch 13. For example, as the electric motor 14 is locked, the inter-terminal voltage of the auxiliary winding 17 is decreased, this state is detected by the relay coil 19 to operate the relay switch 13 and to shut off a power supply. It prevents positively a high current from flowing to the windings 15 and 17 and at the same time it may operate an informing lamp 16.

摘要： PURPOSE:To obtain excellent safety by providing the first and second switches turned off after a preset time and a fixed time from the cooking start respectively and the third switch turned on when the temperature of a magnetron or the like becomes a fixed value or above and connecting the third and second switches in parallel. CONSTITUTION:A timer 11 is operated at the time of cooking, and a switch 11b is turned off when three minutes elapse from the cooking start in this case. A thermal switch 20 is ordinarily turned on after the temperature rise of a magnetron 10 and the temperature rise of a heating chamber wall, and the oscillation operation of the magnetron 10 is continued. When the preset time elapses, a switch 11a is turned off, the oscillation operation of the magnetron 10 is stopped, and cooking is completed. When a short circuit failure occurs on the magnetron 10 or a high-voltage diode 9, the oscillation operation of the magnetron 10 is not started even if the excitation of a high-voltage transformer 6 is started. The temperature of the magnetron 10 and the heating chamber wall does not rise, and the thermal switch 20 is kept off. The switch 11b is turned off at three minutes after the cooking start, thereafter the transformer 6 is not excited.

摘要： PROBLEM TO BE SOLVED: To lock the outer ring of a ball bearing with respect to the bearing box. SOLUTION: A plurality of recesses 12c are made in the inner circumferential surface of a bearing box 12b formed in a frame 13. A plurality of rod-like bodies 19 are bonded to the outer circumferential surface of the outer ring of a ball bearing 18 and each rod-like body 19 is fitted in the recess 12c. When such a structure is employed, rotation of a rotary shaft 22b is transmitted to the inner ring of the ball bearing 18 and the balls thereof roll to apply a rotating force to the outer ring. But since each rod-like body 19 is fitted in the recess 12c, the outer ring is sustained in stationary state.

摘要： PURPOSE:To maintain the operational safety of a device even if to actuation of a relay occurs and also to miniaturize the device by turning on the single- throw contact of a switching means for exciting the relay and inserting a heater in the primary winding of a high-tension transformer via the double-throw contact of the switching means until this relay contact is turned on. CONSTITUTION:When a heating mode is set for microwave heating, then a single-throw contact 11 is turned on, while a double-throw contact 12 is connected on one side indicated at the second letter of the Japanese alphabet or KATAKANA. Although in this condition turning on a starting switch 2 causes a relay 5 to be excited, a time of a few milliseconds is required until a contact 5a in the relay is turned on. Curing this time, a heater 4 is allowed to be inserted in the primary winding 71 of a high-tension transformer 7 in series to the winding, whereby a rush current may be reduced to its low level. After that, when the normally off contact 5a in the relay 5 is turned on, the heater 4 is set in its short-circuited condition, and therefore supply voltage in its entirety is fed to the primary winding 71 of the high-tension transformer 7, whereby a magnetron can be oscillated.

SOLUTION: A plurality of stoppers 26a, 27a, 26b, 27b, 26c, 27c are projected from the inner circumferential surface of a front frame 14 of a motor frame 11 at intervals, in both the circumferential direction and the axial direction. Either one of the pair of the stoppers corresponding to the thickness of a stator core 16 are selected from a plurality of pairs of these stoppers, when the stator core 16 is pressed into the front frame 14 of the motor frame 11, and made to correspond and placed to a pair of the stoppers selecting a fitting section 16a. When the stator core 16 is pressed in gradually in this state, the stator core 16 is stopped, when the fitting section 16a is abutted against the stopper and fixed at these places.

摘要： PURPOSE:To obtain sufficient protection with a fuse built in a microwave oven by feeding power to a magnetron and a heater through each exclusive feed path having a fuse respectively on one power bus line, and concentratively providing control switches on the other power bus line. CONSTITUTION:When cooking is to be performed with a magnetron 1, a selector switch 11 is turned on, and a timer is set. A timer switch 12 is turned on, power is fed to a high-voltage transformer 2 via a feed path 14, and the magnetron 1 is oscillated for cooking. If an abnormality occurs and a large current flows in the primary winding 2a, for example, a fuse 8 is blown out, and the feed path 14 is protected. A plug fuse 6 is set larger than the total cutoff capacity of both fuses 8, 16, and it is not melted first. When cooking is to be performed with a heater 4, a selector switch 17 is turned on, and a timer is set. Power is fed to the heater 3 via a feed path 18 for cooking. If a large current flows in the feed path 18, the fuse 16 is blown out to protect the feed path 18.

摘要： PURPOSE:To prevent an opened door from fitting against a face or a body of a user by a method wherein at first a state of opening door is informed when the door opening operation is started in a cooking unit such as a microwave oven and after informing it, a door opening device is driven. CONSTITUTION:A cooking unit is provided with a door opening motor 5 for releasing a door of a heating chamber, a buzzer for informing an opened door in case of opening the door and means for driving the motor 5 at the informing part. When the cooking is completed, a door opening key is touched, a control part may ring the buzzer for a specified period of time and the fact that the door is opened is displayed at a displaying unit for a specified period of time. As the motor 5 is operated, a cam 6 is rotated and a pin 7 pushes up a lever 8. In this way, when a hook 2 is lifted up, an engagement between the hook 2 and a hook receptacle 4 is disengaged, and then a door 1 is released by an elastic force of a spring. In this case, the control part stops the driving of the motor 5.
