Problems solved by technology

For a long time, the prior art has adopted this left and right structure, that is, the latch part is arranged on the side of the rotor, so that the structure of the operating device cannot be more compact, and this structure makes the knob resist the gradually increasing resistance. The rotation process is not smooth enough, which affects the user's feel and is easy to wear the operating device

Abstract

The invention relates to a rotary knob type operation device of a household electric appliance and the household electric appliance. The rotary knob type operation device comprises a rotating shaft, a rotating piece, a fixed piece, a track and a protruding piece. The track is arranged on one of the rotating piece and the fixed piece and comprises at least one slope. The protruding piece is arranged on the other one of the rotating piece and the fixed piece. The protruding piece elastically abuts against the track in the direction parallel to the extending direction of the rotating shaft. When the rotating shaft drives the rotating piece to rotate, the protruding piece relatively moves on the track. The rotating shaft can resist gradually-increasing resistance generated when the protruding piece goes up the slopes to rotate. The rotary knob type operation device of a different technical concept is more compact in structure, and a user can obtain the hand feeling that the rotating resistance gradually increases when operating the rotary knob type operation device.

Description

【Technical field】 [0001] The invention relates to a household appliance, in particular to a knob-type operating device of the household appliance and the household appliance with the knob-type operating device. 【Background technique】 [0002] For some household appliances controlled by a knob, the user can obtain a feeling of gradually increasing rotation resistance when the user turns the knob. Once the user lets go, the knob will automatically rotate to a certain extent. The prior art utilizes the cam principle to realize this function, for example, the Chinese invention patent application CN102420068A belongs to such a structure. The rotor has latch openings in the radial direction, and the latch openings have slopes. When the rotor rotates, the latch components arranged on the side of the rotor can relatively move along the slopes, thereby giving users a feeling of increased rotation resistance. For a long time, the prior art has adopted this left and right structure, t...
