Embodiment 1

[0024] The invention is mainly used for a range hood with a press control function, and is composed of a hood operating system, a hood control system and a hood execution system. The hood operating system mainly provides basic operation functions, using magnetically controlled knobs. The basic functions set by the system include switching on and off, motor gear adjustment, and switching lights. Other auxiliary functions are added or deleted according to product applications. The operating system is set according to requirements: Functions such as power button, motor gear button and lighting button. The circuit control component 2 of the magnetic control knob is fixedly installed on the back of the operating glass panel 3 of the hood, and the knob switch component 1 is placed at the corresponding position on the front of the panel, using the positioning function of the ring positioning magnet 1-2 and the ring positioning magnet 2 2-3 , the knob will be reliably attached to the ...

Embodiment 2

[0026] The invention has high versatility and can be interoperable with other products with the magnetic control function.

Abstract

The invention discloses a magnetic-controlled rotary knob with a pressing control function and an extractor hood. The magnetic-controlled rotary knob is characterized by comprising a rotary knob switch module and a circuit control module corresponding to the rotary knob switch module; a control main magnet and an annular positioning magnet one are arranged in the rotary knob switch module; the control main magnet is arranged at a center hole of the annular positioning magnet one; a control chi, a magnetic induction chip and an annular positioning magnet two are arranged in the circuit controlmodule; the annular positioning magnet one and the annular positioning magnet two are distributed in back and forth or up and down, and an infrared induction module is arranged beside the magnetic induction chip; the magnetic induction chip is connected with a control chip, and the magnetic induction chip judges different angle locations of the rotary knob switch module, and returns the judgment information to the control chip. The magnetic-controlled rotary knob disclosed by the invention is simple in structure and convenient to operate and use.

Description

technical field [0001] The invention relates to the field of range hoods, in particular to a magnetic control knob with a press control function and a range hood. Background technique [0002] Existing kitchen appliances already use magnetically controlled knob switches, which are mainly used in cooker categories. The firepower and time of the cooker can be adjusted by rotating the knob. The function of the knob is relatively single, and it cannot exist independently to replace all control functions. It needs to cooperate with other buttons to realize all function control of the corresponding product. The existing technology realizes the pressing function by sensing the change of the magnetic field strength of the main magnet in the knob, but the thickness of the panel glass of different products is different, and the induction of the magnetic field strength is related to the displacement and stroke of the knob. There are obvious differences in the thickness of the operatio...
