Detailed Description
In order that the above-recited objects, features and advantages of the present invention will be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be noted that, in the case of no conflict, the embodiments of the present application and the features in the embodiments may be combined with each other.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those described herein, and therefore the scope of the present invention is not limited to the specific embodiments disclosed below.
A knob device 100 and a cooking appliance provided according to some embodiments of the present invention are described below with reference to fig. 1 to 5.
Example 1:
as shown in fig. 1 and 2, the present invention provides a knob device 100, which includes an electrical control, a connection assembly 120 and a knob 160, wherein the three are sequentially connected, that is, one side of the connection assembly 120 is connected with an electrical control element, and the other side is connected with the knob 160.
Specifically, the connection assembly 120 includes a first connection portion 122 and a second connection portion 124, the electric control member includes a rotation portion 112, the first connection portion 122 is connected with the rotation portion 112, the second connection portion 124 is connected with the knob 160, and the knob 160 can drive the rotation portion 112 to rotate through the second connection portion 124 and the first connection portion 122, and the rotation of the rotation portion 112 can realize adjustment of the electric control, so as to control the electric appliance.
Further, as shown in fig. 2, a three-dimensional rectangular coordinate system is established, the knob 160 may rotate about the rotation axis a, which extends in the second direction, specifically, the Z-axis direction of the three-dimensional rectangular coordinate system, and the first connection part 122 and the second connection part 124 may perform relative movement in a first direction different from the Z-axis direction, and, due to the relative movement, the first direction may actually include two directions opposite to each other, i.e., positive and negative for the vector direction.
The first direction may be any direction different from the Z-axis direction, that is, it may be decomposed into an X-axis direction or a Y-axis direction.
Therefore, when the electric control part is installed, if the electric control part cannot be aligned with the installation hole of the knob device 100 on the casing of the cooking appliance due to the internal layout of the cooking appliance, that is, when the rotating part 112 of the electric control part is inclined or deviated, the connecting component 120 can utilize the relative movement of the first connecting part 122 and the second connecting part 124 to correct the electric control part, so that the knob 160 is still at a preset position, the assembly difficulty of the cooking appliance is reduced, the knob 160 cannot be scraped with the casing of the cooking appliance when rotating, abnormal noise caused by rotation of the knob 160 is avoided, the uniformity of stress of the knob 160 is ensured, and the service life of an electric appliance is prolonged.
And, after the installation is accomplished, if the electric control is because of long-time use and appears the slope or the offset scheduling problem, coupling assembling 120 still can utilize the relative activity of first connecting portion 122 and second connecting portion 124, correct it, and then guarantee knob 160 still to be in the preset position, reduce cooking utensil's assembly degree of difficulty, and, make knob 160 can not scrape mutually with cooking utensil's shell when rotatory, abnormal sound when having avoided knob 160 to, guarantee that the atress of knob 160 is even, promote the life-span of electrical apparatus.
Here, the first direction and the second direction are vectors, and therefore, the first direction and the second direction are defined to be different and not opposite, but since the first connection portion 122 and the second connection portion 124 perform relative movement, the directions in which the first connection portion 122 and the second connection portion 124 are movable are actually the first direction and the negative first direction.
Specifically, the electrical controls may be fixedly connected with the connection assembly 120, such as: clamping, screwing or connecting through screws.
Further, the electrical control is a printed circuit board, and an encoder is welded on the printed circuit board, and a rotating part 112 is arranged on the encoder.
Example 2:
as shown in fig. 2, further, on the basis of embodiment 1, the first connection part 122 and the second connection part 124 may also perform relative movement along a third direction different from the Z-axis direction, and the third direction is different and not opposite to the first direction, and the third direction is also different and not opposite to the second direction.
In this embodiment, the first connecting portion 122 may perform relative movement in the third direction on the basis of the relative movement in the first direction, so that the vectors in the first direction and the third direction are superimposed, the relative movement ranges of the first connecting portion 122 and the second connecting portion 124 may form a circular area, and the movement ranges of the first connecting portion 122 and the second connecting portion 124 are further enlarged, so that when the electric control member is tilted or deviated in any direction, the connecting assembly 120 can adjust the connection position between the electric control member and the knob 160.
Here, the first direction, the second direction, and the third direction are vectors, and therefore, the third direction and the first direction are defined to be different and not opposite, and the third direction and the second direction are defined to be different and not opposite, but since the first connection portion 122 and the second connection portion 124 perform relative movement, the directions in which the first connection portion 122 and the second connection portion 124 can actually move are the third direction and the negative third direction.
Example 3:
as shown in fig. 2, on the basis of embodiment 1 or embodiment 2, further, the connection assembly 120 includes: the housing and a transmission system at least partially disposed within the housing, wherein both the first connection 122 and the second connection 124 are disposed on the transmission system.
