Problems solved by technology

[0009] In the microwave oven of the prior art, the cooking process does not provide any countermeasures for the changes in the cooking environment caused by opening the oven door in the above working state, so it has a certain impact on the cooking effect
[0010] Specifically, after the oven door is opened under the cooking state of the microwave oven, the heat in the oven cavity is dissipated, the temperature of the food in the oven and the cooking environment all change, but the cooking time determined by the timer does not change. Therefore, the oven door Cooking dishes that continue to be completed after closing cannot achieve the preset satisfactory results

Embodiment Construction

[0034] The feed-forward control method after the microwave oven door is opened according to the present invention will be further described in conjunction with the accompanying drawings. As shown in Figure 3, the control method involved in the present invention comprises the following five steps: S 1 , Furnace door state detection, S 2 , time storage and temperature measurement, S 3 , time reading and temperature measurement, S 4 , Compensation time calculation, S 5 , Continue cooking.

[0035] After the furnace door is opened, it enters the furnace door state detection S 1 , set the door open flag, stop cooking; then enter the time storage and temperature measurement S 2 , store the remaining set working time T 1 , measure the chamber temperature t 1 , the relay is not allowed to work, and the furnace door is opened at the same time; then time reading and temperature measurement S 3 , read the furnace door opening time T, measure and read the furnace chamber temperatu...

Abstract

A feedforward control method after the door of microwave oven in working state is opened for compensating the lowered temp includes such steps as detecting the state of door, storing time and measuring temp, reading out time and measuring temp, calculating the compensating time, and continuous cooking according to compensating time.

Description

technical field [0001] The invention relates to a microwave oven, in particular to a control method for the microwave oven. Background technique [0002] A microwave oven is a household appliance cooker that uses high-frequency microwaves to heat food. It heats and cooks food through the frictional heat generated by the violent vibration of food molecules under the action of high-frequency microwave radiation. When cooking in a microwave oven, the microwave penetrates the food and can heat the inside and outside at the same time, which has many advantages of high efficiency, fast speed and convenient application. Therefore, microwave ovens have gradually become widely used household appliances. [0003] The appearance of the microwave oven is in the shape of a cuboid, the front of the cuboid casing has a furnace door, and an operation key is arranged on one side of the furnace door. A furnace cavity is formed in the shell, and the internal components of the microwave oven ...
