Title: Power supply device for microwave oven, and high-voltage fuse used for the device
Inventor: LEE GYE-HONG
IPC: H05B6/68
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a power supply device, in which full length of an insulator of a high-voltage fuse is shortened and which can be easily assembled in a microwave oven for installation, by connecting a high-voltage fuse to a grounding end of a secondary coil of a high-voltage transformer. SOLUTION: An output end of a high-voltage transformer 10 has a high- voltage capacitor HC for charging and discharging high-voltage current, and one side of a high-voltage fuse 30 is connected to a grounding end of a secondary coil T2 of the high-voltage transformer 10. With this structure, an electrical potential difference between the high-voltage fuse 30 and the grounding surface becomes to 20 V or less at the time of normal operation of a microwave oven, and in the case where the high-voltage fuse 30 is disconnected, high voltage is applied to one end of the high-voltage fuse 30, but the other end thereof is grounded so as to stop the application of voltage. Consequently, since the insulation is performed by grounding only one part of the high-voltage fuse 30, which is connected to the high-voltage transformer 10 among the structural parts of the fuse 30, full length of the high-voltage fuse 30 can be shortened.

IPC: G10H1/12
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To suppress the influence of return noise with simple configuration by providing a modulator and a band-pass limiting filter for reducing noise due to the modulator on at least one of two signal transmission lines. SOLUTION: A digital time-series signal is inputted from an input terminal IN1 and inputted to the modulator 12 through a low-pass filter 11 arranged on the signal transmission path L1. Another digital time-series signal is inputted from an input terminal IN2 and inputted directly to the modulator 12 through the signal transmission line L2. The modulator 12 imposes ring modulation with the two input signals and outputs the result from an output terminal OUT. The maximum frequency of the ring modulation is the sum frequency of the highest frequencies of the two input signals and no return noise is generated when the Nyquist frequency is not exceeded. Here, the low-pass filter 11 limits the bands of the input signals to obtain a signal of frequency below the Nyquist frequency.
