摘要： A microwave oven having a high voltage control circuit which prevents an overheating of a high voltage transformer. The high voltage control circuit includes a thermostat which is turned on or off according to a temperature of the high voltage transformer. The thermostat is disposed between a first fixed terminal of a tap formed at a primary coil of the high voltage transformer and a second fixed terminal connected to a power stage, so as to allow the primary coil to have different numbers of turns. According, where the output of a magnetron of the microwave oven becomes high and the temperature of the high voltage transformer reaches a predetermined temperature, the thermostat is turned off, thus enabling the first and second fixed terminals to be disconnected from each other. Therefore, the number of turns of the primary coil of the high voltage transformer is increased and the voltage supplied to the magnetron is decreased, thus maintaining the decreased output of the magnetron and preventing the overheating of the high voltage transformer.

摘要： A heating chamber has a width in a direction of a two-head arrow X, a depth in a direction of a two-head arrow Y and a height in a direction of a two-head arrow Z. An infrared sensor includes 25 infrared detection elements each having a field of view. Since the 25 infrared detection elements are arranged, five by five in directions Y and Z, on the heating chamber's bottom plate there are projected a total of 25 fields of view, five by five in directions Y and X. Thus the bottom plate has any area thereof covered by one of the 25 fields of view.

摘要： Timing of zero voltage in zero-voltage detector for detecting zero voltage of a commercial power supply 1 is predicted and input from the zero-voltage detector 6 is received only for a given time before and after the predicted timing, whereby overvoltage and overcurrent caused by a zero point shift can be prevented. Thus, it is provided a magnetron drive power supply which is excellent in stability for change in the power supply environment such as noise or instantaneous power interruption.

摘要： A microwave oven with an apparatus for detecting life time of components detects a frequency of opening and closing of a door switch even when AC power supply is cut-off, and detects a driving time of a high voltage transformer or a magneton according to their driving status, and accumulates and stores the detected driving time in a memory. The microwave oven includes a high frequency generation detecting portion connected to a high frequency generating portion for detecting driving status of high frequency generating components such as the high voltage transformer or the magnetron, and a door opening/closing detecting portion for detecting opening and closing of the door. A microcomputer counts the driving time of We high frequency components and the frequency of door opening and closing, and accumulates and stores the counted result in the memory. The accumulated result stored in the memory is displayed in as display portion by a key manipulating portion for a notice of a user so that the user can check the driving time of the components.

摘要： A microwave oven comprises a magnetron having an anode, a cathode and a filament, and a high voltage transformer having a primary coil and a secondary coil for supplying a high voltage to the magnetron. The microwave oven further comprises a capacitor connected in parallel to the secondary coil of the high voltage transformer, forming a resonance circuit with the secondary coil. With this configuration, the performance of the magnetron is maintained by lowering the anode peak voltage applied thereto during the early non-oscillating period, and the circuit elements are protected from damage by removing the surge voltage.

摘要： A compact and highly controllable impedance-varying-unit, a microwave device using the same unit, and a high-frequency-heating appliance using the same unit are provided. The impedance varying unit includes a rectangular waveguide-section as a main body made of metallic material, an open end of waveguide-section working on microwave in a microwave cavity, a terminal end of waveguide-section closed by metallic material, a rotary movable body made of non-metallic material, and a driver for the movable body. A rotating angle or a position of the movable body is controlled, so that an impedance at the open end is varied and transmission status of microwave is changed, thereby variably controlling a standing wave distribution. Controlling the standing wave distribution allows an object in the cavity to be selectively heated or uniformly heated. Further, the standing wave produced in the microwave cavity is sequentially varied, so that the object can be selectively heated or uniformly heated. The present invention solves the problem of spark production, and provides a compact as well as highly controllable impedance varying unit, a microwave device using the same unit and a high-frequency-heating appliance using the same unit.

摘要： A microwave polymerization system for dentistry utilizes specifically controlled microwave energy to cure polymer materials so as to produce dental prosthetics, such as dentures, bridges and crowns, that are made in an extra-oral setting such as a dental laboratory or dental office, and to create dental composites for fillings and veneers that are used in an intra-oral setting directly in the patient's mouth. Unlike the microwave energy delivered by commercial microwave ovens which is controlled by pulsing a maximum voltage pulse on and off at a given duty cycle, the system utilizes metered and controlled microwave energy that is preferably continuous and voltage controlled, and regulates the application of this microwave energy by use of various feedback and control mechanisms. The metered and controlled microwave energy enables a higher degree of conversion of monomers into polymer chains in the polymerization process, thereby enhancing the physical and biocompatibility characteristics of both dental prosthetics and dental composites made from polymers. In an extra-oral embodiment, gaseous pressure is applied to the resin matrix during the polymerization process to further enhance the polymerization process. In an intra-oral embodiment, the polymerization process can be accomplished with less overall energy and with composite-matrices that maximally absorb the microwave energy so as to reduce heating of adjacent tissue.
