[0096] Compared with the first embodiment, in this embodiment, further processing is performed on the case that the temperature fluctuation level is less than or equal to the fluctuation level threshold. By judging whether the steady-state temperature is greater than the temperature threshold, if it is greater than the temperature threshold, it means that the current temperature at the burner is also at a very high temperature, and it is directly recognized that the gas stove has been ignited, so the range hood is controlled to start.
[0097] In this embodiment, the steady-state temperature is calculated based on the temperature change of the samples before and after adding the current sampled temperature, specifically as follows:
[0098] Obtain the temperature of the current cycle and the temperature sampled in the previous cycle within the time window;
[0099] The steady-state temperature is determined from the temperature of the current cycle and the temperature sampled fr...

The invention relates to the field of kitchen appliances, and discloses a control method for a range hood, a controller, a control device and the range hood. The temperature, detected in a time window, of a furnace end region of a gas stove is acquired, the temperature fluctuation level in the time window is determined according to the acquired temperature, finally, starting of the range hood is determined according to the temperature fluctuation level, thus, ignition of the gas stove can be accurately recognized, and automatic control over the range hood is achieved. By the adoption of the method, the parameter requirement on an infrared sensor is low, the single-point acquisition low-cost infrared temperature sensor can be adopted, the response speed can be rapidly recognized, good recognition accuracy is achieved, and therefore the reliability and the accuracy of linkage control of the range hood and the gas stove at low cost are achieved.
Description
technical field [0001] The invention relates to the field of kitchen appliances, in particular to a control method for a range hood, a controller, a control device and the range hood. Background technique [0002] The existing ones used for smoke cooker linkage control generally use infrared temperature sensors to detect the average temperature change within the range of the cooktop, so as to judge the working status of the cooker, and realize the estimation of the concentration of oil fume according to the temperature change curve, so as to control the oil fume the operating status of the machine. This technical solution has high requirements on the technical parameters of the infrared temperature sensor, resulting in high cost of the sensor, making it difficult to apply it on a large scale in products. Contents of the invention [0003] The purpose of the embodiment of the present invention is to provide a control method, a controller, a control device and a range hood ...
