Problems solved by technology

However, there are many disadvantages in this existing technical solution: First, the working principle of the sliding rheostat determines that the accuracy of its gear position detection is not high, and it is difficult to be effectively applied to the gear position adjustment with a small rotation range of the rotary rod. In terms of mechanism; secondly, because the resistance wire directly rubs against the sliding plate, it is easy to cause the wear of the resistance wire, which will affect the service life to a certain extent, and the maintenance cost is high

Abstract

The invention provides a novel gear detection device and a combination of the household electric appliance, a cooker and a smoke exhaust ventilator with the adoption of the gear detection device. The gear detection device used for the household electric appliance comprises a detecting module, rotating modules, a detection circuit and elastic pieces. The household electric appliance comprises a rotating rod used for gear switching. The elastic pieces form switches of the detection circuit. The detecting module is used for detecting electric signals of the detection circuit. The rotating modules are connected with the rotating rod in a linkage mode. When the rotating rod rotates, the rotating modules extrude the elastic pieces, switching conditions of the detection circuit are further changed, and the electric signals detected by the detecting module are changed; the detecting module is used for determining corresponding gears according to the detected electric signals. According to the technical scheme, the gear detection device can be possibly and effectively used for a gear regulating mechanism with a smaller rotating range of the rotating rod.

Description

【Technical field】 [0001] The invention relates to the field of household electrical appliances, in particular to a cooker and a gear detection device thereof. 【Background technique】 [0002] Many household appliances are equipped with mechanical gear adjustment mechanisms, such as gas stoves. With the increasing intelligence level of household appliances, gear detection technology for mechanical gear adjustment mechanism has gradually become a technical hotspot. Wherein, for the mechanical gear adjustment mechanism of the rotary rod type, in the prior art, a sliding rheostat is generally used to detect the gear position. However, there are many disadvantages in this existing technical solution: First, the working principle of the sliding rheostat determines that the accuracy of its gear position detection is not high, and it is difficult to be effectively applied to the gear position adjustment with a small rotation range of the rotary rod. In terms of mechanism; secondly,...
