Embodiment Construction

[0040] The specific methods, steps, features and effects of the control method for high-voltage transformers for microwave ovens according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.

[0041] see Figure 7 Shown is a block diagram of the microwave oven transformer control method of the present invention.

[0042] In the control method of the high-voltage transformer for microwave ovens of the present invention, the high-voltage transformer 25 for microwave ovens will form a half-wave voltage doubler circuit for magnetron 30 to generate microwaves with a start-up circuit. The power supply unit 5 supplies power to the above-mentioned high-voltage transformer 25 .

[0043] The said high-voltage transformer 25 of the present invention is characterized in that, as the design requirement of common high-voltage transformers for microwave ovens, its maximum service time is specified as 90 minutes. ...

Abstract

This invention relates to a method for controlling microwave oven high voltage transformer which is designed for the operation time, power supply of the transformer is controlled to the maximum output power of a certain period of time at the beginning, and its output power is controlled and reduced after a certain time, the level of which is controlled to more than two output power changes and designed according to the actual time used by a microwave oven at the beginning. This invention is for designing the best microwave oven high voltage transformer which can adjust temperature of the cable core.

Description

technical field [0001] The present invention relates to a control method for transformers in the basic electrical components in the field of electricity, in particular to an optimal design that not only meets the requirements of transformers, but also adjusts the temperature rise of the cable core harness by controlling the action cycle of the transformers, so that the high-voltage transformers A control method for H.V.trans formicrowave oven with reduced weight and lower production cost. Background technique [0002] Magnetrons used in microwave ovens generate microwaves, and when the above microwaves are irradiated to food, the molecules inside the food will rotate or vibrate at the same speed as the frequency of the microwaves. When such a vibration or rotation is achieved, the frictional heat that occurs between the molecules will rapidly increase the temperature of the food. [0003] The oscillator for generating the above-mentioned microwaves is a magnetron, and a vol...
