Range hood, stove system and control method

Abstract

The invention discloses a range hood, a stove system and a control method for the range hood. The control method for the range hood includes respectively setting a first trigger threshold, a second trigger threshold and a third trigger threshold; setting a motor in the range hood The specific rotation speed and detection cycle during high-speed operation and low-speed operation; detect the switch action of the cooker knob, and judge whether the cooker is in the enabled state; detect the pressure value of the cooker; judge the range of the pressure value, adjust the motor speed; enter the next detection cycle. This technical solution first detects the switch action of the cooker knob to determine whether the cooker is in the activated state, so as to avoid falsely triggering the start of the range hood; then detects the pressure value of the cooker through the pressure sensor, and indirectly identifies the cooker's current state through the pressure value of the cooker. According to the current cooking action, it judges whether oil fume will be generated, and then automatically adjusts the motor speed in the range hood.

Description

technical field [0001] The invention relates to the technical field of kitchen and bathroom equipment, and more specifically relates to a range hood, a stove system using the range hood and a control method for the range hood. Background technique [0002] In recent years, with the continuous application and popularization of intelligent technology, but because domestic cooking habits often use frying, frying, deep-frying, etc., especially after the oil is heated, a lot of oily smoke will be generated when the ingredients just touch the pot. At this time, it is necessary to Exhaust smoke in time. [0003] In the prior art, the range hood mainly extracts the oil fume through the following three schemes. The first is to keep the range hood at a constant and large exhaust air volume for a long time, and when the oil fume is generated, it can be extracted and eliminated in time. But the cooking fume is only produced in a large amount at a certain time. If the range hood runs at...

Problems solved by technology

[0003] In the prior art, the range hood mainly extracts the oil fume through the following three schemes. The first is to keep the range hood at a constant and large exhaust air volume for a long time, and when the oil fume is generated, it can be extracted and eliminated in time. But the cooking fume is only produced in a large amount at a certain time. If the range hood runs at high speed for a long time, the power and noise will be large, resulting in waste of resources and discomfort for the cook; the second is to use a smoke sensor or temperature sensor. Increase the speed of the motor in the range hood to eliminate the instantaneous oil fume. Due to the hysteresis of the sensor, the oil fume overflows to detect and take action, which often causes the oil fume to escape; the third is to set a motor speed-up time , Before cooking, start this function to remove the instant cooking fumes. This solution is not intelligent enough, users often forget to start the function, and the motor speed-up time is a fixed value, which often does not match the cooking fume generation time, resulting in waste of resources

To sum up, the current oil fume extraction scheme of the range hood mainly has insufficient intelligence, and it is impossible to adjust the motor speed in the range hood according to the specific cooking process of the user.
