[0085] Based on the first embodiment, the second embodiment of the cooking control method of the present invention is proposed, referring to Figure 4 , in this embodiment, the signal receiver is used to receive the reflected wave after the electromagnetic wave emitted by the signal transmitter is reflected by the cooking cavity, and step S3000 includes:
[0086] Step S3100, generating a first standing wave based on the electromagnetic waves received by the signal receiver within the first preset time interval and the electromagnetic waves emitted by the signal transmitter within the first preset time interval;
[0087] Wherein, the first preset time interval can be reasonably set according to requirements.
[0088] In this embodiment, when the signal receiver receives the reflected wave of the electromagnetic wave emitted by the signal transmitter and reflected by the cooking cavity, the electromagnetic wave received by the signal receiver within the first preset time interva...

The invention discloses a load detection method which is applied to a cooking utensil. The cooking cavity of the cooking utensil is provided with a load detection device. The load detection device comprises a signal emitter and a signal receiver. The load detection method comprises the following steps of upon receiving a cooking instruction, controlling the signal transmitter to send electromagnetic waves in accordance with a preset power and / or a preset frequency; acquiring electromagnetic waves received by the signal receiver; and determining whether the cooking utensil is in a no-load stateor not based on the acquired electromagnetic waves. The invention further discloses a load detection device and a computer readable storage medium. According to the invention, whether the cooking utensil is in the no-load state or not is determined according to the electromagnetic waves. The load state of the cooking utensil can be accurately detected through electromagnetic waves emitted by theload detection device. The accuracy and the detection efficiency of the load detection of the cooking utensil are improved.
Description
technical field [0001] The invention relates to the technical field of cooking, in particular to a load detection method, device and computer-readable storage medium. Background technique [0002] With the increasing popularity of cooking utensils such as microwave ovens and ovens, the demand for diversified functions is also increasing. If cooking utensils such as microwave ovens and ovens work without food in the cooking cavity of the cooking utensils, that is, under no-load conditions, it will not only waste electricity, but also may damage the electrical appliances, thereby affecting the service life of the cooking utensils. Therefore, it is necessary to detect whether there is a load in the cooking cavity, so as to prevent the cooking appliance from working without a load. [0003] Taking a microwave oven as an example, in order to detect whether the microwave oven is in the no-load state, in the prior art, the anode current of the magnetron is detected while starting ...
