Embodiment Construction

[0038] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] refer to figure 1 , an embodiment of a control method for a microwave oven according to the present invention is proposed. The control method of the microwave oven comprises the following steps:

[0040] Step S10, detecting the relative humidity and temperature in the microwave oven;

[0041] Because microwave ovens produce steam when heating food. Therefore, a relative humidity sensor is provided in the microwave oven for periodically detecting the relative humidity and temperature in the microwave oven.

[0042] Step S20, according to the relative humidity in the microwave oven, determine whether the microwave oven is empty; if yes, go to step S50; otherw...

Abstract

The invention discloses a microwave oven control method and a device, as well as a microwave oven. The microwave oven control method comprises: detecting the relative humidity and temperature in the microwave oven; according to the relative humidity in the microwave oven, judging whether the microwave oven is in a non-loaded state, and if the non-loaded state exists, making the microwave oven stop working; or else, continuing detecting the relative humidity and temperature in the microwave oven, and according to the relative humidity and temperature of the microwave oven as well as the preset relative humidity and temperature, judging whether heating of the food in the microwave oven is completed; if the heating is completed, making the microwave oven stop working; if the heating is not completed, making the microwave oven continue to work, and returning to the step of continuing detecting the relative humidity and temperature in the microwave oven. In the invention, control of the microwave oven is realized through a simple control mode. And by detecting the relative humidity and temperature in the microwave oven, whether the microwave oven is in a non-loaded state or whether heating is completed can be judged accurately and timely.

Description

technical field [0001] The invention relates to the field of microwave ovens, in particular to a control method and device for a microwave oven, and a microwave oven. Background technique [0002] Humidity sensing is not new in the microwave oven industry, and there are already many microwave ovens with humidity sensing function on the market. The user only needs to select the food type, press start, and does not need to select the time when putting in the food. The microwave oven can automatically calculate the heating time through the steam overflowing during the food heating process. [0003] The existing microwave oven humidity sensor detects the humidity through changes in the resistance of the humidity sensor, etc., and measures the absolute humidity, but cannot measure the temperature. It is also necessary to increase peripheral amplification and filter circuits to convert the output signal of the sensor. Therefore, the control structure is not only complicated, but...
