Combined regulating and controlling device for microwave oven

Abstract

This invention discloses a regulating and controlling device of microwave, in addition to a regular method. In the microwave oven it has a magtron as heating source, a heater and a circulating fan making the heated air circulating in the cooking chamber; in the circulating motor which is used for driving circulating motor it leads out T1, T2, T3 terminals, connecting the T2 terminal, T3 terminal to the power source input end of the heater, wherein the voltage between the T2 and T3 terminal is smaller than the set voltage. In the heating mode, applying the set voltage in the heater and operating the heater only; in the association mode, cutting off the set voltage in the heater, applying the voltage between T2 and T3 terminal, making the heater and magtron working together. In the association mode, the heater and the magtron will drive together, by which can cook quickly and evenly.

Description

technical field [0001] The invention relates to a microwave oven equipped with a heater, in particular to a combined control device for a microwave oven using a combined mode to realize fast cooking. Background technique [0002] Recently, a gas range, a gas oven, a microwave oven, a microwave oven, and the like are mainly used as cooking devices for household use. [0003] Wherein, the microwave oven is a cooking machine in which the microwave generated by the vibration of the built-in magnetron (MGT) is used as the main heating source to heat the food inside the cooking chamber. [0004] In addition, microwave ovens with built-in heaters to provide various heating states have been recently developed and launched. [0005] A microwave oven with a built-in heater is useful in heating food by selectively using heat generated by a heater as a heating source and microwaves generated by a magnetron. [0006] With the development of microwave ovens equipped with magnetrons and ...

AI Technical Summary

Problems solved by technology

[0021] First, in the joint mode, there is a limit to the variable output of the magnetron due to the heating method in which the magnetron must be disconnected when the heater is connected

[0022] Second, due to the limitation of the allowable current set in the combined mode of the microwave oven, the magnetron and the heater cannot operate at the same time, it is impossible to achieve fast cooking, and there are difficulties in shortening the cooking time
