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

Embodiment Construction
[0032] In order to have a further understanding of the purpose, structure, features, and functions of the present invention, the following detailed descriptions are provided in conjunction with the embodiments.
[0033] The invention provides a knob type operating device, which can be used on household appliances such as washing machines, refrigerators, gas stoves, electromagnetic stoves, coffee machines, dishwashers, disinfection cabinets and other household appliances that can be operated and controlled by knobs. The type operating device is shown as an example, but the present invention is not limited to this. Please refer to Figure 1 to Figure 4 , figure 1 This is an exploded view of a knob-type operating device for household appliances in an implementation of the present invention; figure 2 for figure 1 The assembled perspective view of the knob type operating device shown; image 3 Is a perspective view of a rotating member according to an embodiment of the present inventi...

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 a household appliance having the knob type operating device. 【Background technique】 [0002] For some household appliances controlled by the knob, the user can obtain a feeling that the rotation resistance gradually increases during the process of rotating the knob. As soon as the user releases the knob, the knob will automatically rotate to a certain extent. The prior art uses the cam principle to achieve this function. For example, the Chinese invention patent application CN102420068A belongs to such a structure. The rotor has a latch opening in the radial direction, and the latch opening has an inclined surface. When the rotor rotates, the latch component arranged on the side of the rotor can relatively move along the inclined surface, thereby giving the user a feeling of increased rotation resistance. For a long time, the prior...
