Problems solved by technology
[0005] Although the above scheme combines the detection values obtained by the smoke sensor and the temperature sensor to adjust the fan gear, the fan gear is in an incremental and cumulative relationship, and there is no comprehensive control and adjustment based on the speed value corresponding to the smoke value and temperature value, which cannot be achieved. When there is an error in the detection value obtained by one of the sensors, the effect of reducing the error

The invention discloses a method for adjusting the air speed of an extractor hood and the extractor hood. The method for adjusting the air speed of the extractor hood comprises the following steps: obtaining the oil smoke concentration; acquiring the temperature of the stove; and adjusting the rotating speed of a fan according to the oil smoke concentration and the relation between the stove temperature and the rotating speed of the fan. The rotating speed of the fan is correspondingly controlled and adjusted by integrating the two parameter factors of the oil smoke concentration and the stove temperature, the situation that the rotating speed of the fan is not matched with the oil smoke amount due to an error can be compensated when one detection value has the error, and then the matching degree of the actual oil smoke amount and the rotating speed of the fan is improved.
Description
technical field [0001] The invention belongs to the field of kitchen household appliances, and in particular relates to a method for adjusting wind speed of a range hood and the range hood. Background technique [0002] At present, there are two devices used to detect the size of cooking fume in the kitchen: one is an infrared photoelectric sensor that directly detects the smoke concentration based on the principle of refraction of cooking fume to infrared light. The emitted infrared light will be refracted to the infrared light receiving end, and the receiving end circuit will convert the received infrared light into a voltage value output. When the oil smoke is bigger, the infrared rays output from the transmitting end will be refracted into the receiving end more, so that The larger the output value of the receiving end is, the size of the fume is quantified into a specific value. The other is an infrared temperature sensor used to detect the temperature of the cooker. T...
