Abstract

The invention discloses a range hood with an air regulation function and a control system and a control method thereof. The control system of the range hood comprises a power supply module, a motor driving module and a system control module, wherein the system control module comprises a master control chip, a slave control chip and a sensor group, the master control chip is connected with the sensor group, the motor driving module is composed of an intelligent power module, a motor driving chip and a sampling and protection circuit, the sensor group detects the running state of the range hood and inputs the running state to the master control chip, and the master control chip judges the running state of the range hood, then determines an air volume value and sends the air volume value to the motor driving module so as to drive a direct current motor to work. The invention further discloses the range hood and the control method thereof. According to the invention, the problem that influence of a kitchen environment and shared flues on oil smoke absorption effects cannot be integratedly handled in the prior art is overcome, and the range hood is allowed to have the advantages of noise reduction, energy conservation and environment friendliness.

Description

technical field [0001] The invention relates to a range hood with air volume adjustment function, a control system and a control method thereof. Background technique [0002] In the prior art, range hoods generally only have two or three air volume keys. When the motor speed is set, the motor will not adjust the range hood air volume and air pressure according to the actual kitchen environment or cooking method, so that it can be adjusted at any time. Adapt and be in the most reasonable working condition. For example, the air volume required for steaming and stir-frying is different. Generally, high air volume is not required for steaming. If you turn on the highest speed gear during steaming, it will cause unnecessary waste of electric energy. The oil fume or water vapor that is often produced during the cooking process changes at any time. The existing range hoods will not actively detect this change, and adjust the motor speed to change the air volume at any time to adap...
