Microwave oven control method

Abstract

The invention discloses a microwave oven control method. The microwave oven comprises: a main body, a cavity and a convection heater; an auxiliary heating part is arranged on the cavity opposite to the installation position of the convection heater to deliver high-temperature hot air into the cooking chamber. The control method of the microwave oven includes: the first stage: when the convection heater heating mode is selected, the convection heater and the fan motor are powered on, and the high-temperature heat generated by the convection heater enters the cooking chamber; the second stage: the temperature in the cooking chamber reaches the set temperature. temperature, the convection heater is powered off, and the heating element is powered on at the same time; the third stage: after the heating element's power-on time reaches the set time, the heating element is powered off, and the convection heater is turned on again at the same time; the fourth stage: in the During the set cooking time, the above-mentioned 2nd and 3rd stages are repeated in sequence. Advantages: The food can be heated separately from the left and right sides of the cooking chamber, the food is heated evenly throughout, and the convection heater is prevented from overheating.

Description

technical field [0001] The invention relates to a microwave oven and a control method thereof. Background technique [0002] Generally speaking, the ventilated hood microwave oven is installed above the gas stove, and besides having various functions of the microwave oven, it also has the function of air purification, and discharges the hot gas, smoke and peculiar smell generated by the gas stove to the outside. [0003] figure 1 It is a front sectional view of an existing ventilated hood microwave oven; figure 2 for figure 1 The sectional view along the line I-I; image 3 for figure 1 Sectional view along line II-II. [0004] Such as figure 1 , figure 2 and image 3 As shown, the existing ventilation hood microwave oven includes: a body 10 forming an appearance, a cavity 20 formed in the inside of the body 10 to form a cooking chamber, a centrifugal fan 31 for exhausting, and a motor for driving the centrifugal fan 31. Exhaust motor 30, magnetron 41 and high-volt...

AI Technical Summary

Problems solved by technology

[0018] But above-mentioned existing ventilated hood type microwave oven has following shortcoming: because convection heater 51 is arranged on the side of cooking chamber, delivers high-temperature hot gas to cooking chamber, so when the horizontal dimension of microwave oven cooking chamber is bigger, high-temperature hot gas only acts on the food near the convection heater 51

But at this moment, the position close to the convection heater 51 on the food may be overheated, and the phenomenon of being scorched occurs.

[0020] In addition, considering that the convection heater 51 is arranged in the electric control room, if the heating time of the convection heater 51 is too long, other electrical components in the electric control room may be damaged by the heat generated by the convection heater 51, especially with The fan motor 53 used to drive the convection fan 52 may be damaged by high temperature hot air

[0021] Therefore, when the above-mentioned existing ventilated hood type microwave oven works, when the temperature in the cooking chamber or the temperature in the casing 50 rises to the set temperature, the power supply of the convection heater 51 must be disconnected within a certain period of time, and then reconnected. The power supply is repeatedly disconnected and connected, resulting in prolonged cooking time
