Detailed Description
In order that the above objects, features and advantages of the present invention can be more clearly understood, a more particular description of the invention will be rendered by reference to the appended drawings. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
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 specifically described herein, and therefore the scope of the present invention is not limited by 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 comprises an electric control member, a connecting assembly 120 and a knob 160, which are connected in sequence, that is, one side of the connecting assembly 120 is connected to the electric control member, and the other side is connected to the knob 160.
Specifically, the connecting assembly 120 includes a first connecting portion 122 and a second connecting portion 124, the electric control element includes a rotating portion 112, the first connecting portion 122 is connected to the rotating portion 112, the second connecting portion 124 is connected to the knob 160, and the knob 160 can drive the rotating portion 112 to rotate through the second connecting portion 124 and the first connecting portion 122, and the rotation of the rotating portion 112 can realize the adjustment of the electric control element, so as to control the electric appliance.
Further, as shown in fig. 2, a three-dimensional rectangular coordinate system is established, the knob 160 can rotate with the rotation axis a as a rotation center, the rotation axis extends along a second direction, specifically, the second direction is a Z-axis direction of the three-dimensional rectangular coordinate system, and the first connecting portion 122 and the second connecting portion 124 can perform relative movement along a first direction different from the Z-axis direction, and, due to the relative movement, the first direction can actually include two opposite directions, i.e., plus and minus directions with respect to a 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 element is installed, due to the internal layout of the cooking appliance, and cannot be aligned with the installation hole of the installation knob device 100 on the casing of the cooking appliance, that is, when the rotation part 112 of the electric control element is inclined or deviated, the connection assembly 120 can correct the electric control element by using the relative movement of the first connection part 122 and the second connection part 124, thereby ensuring that the knob 160 is still at the preset position, reducing the assembly difficulty of the cooking appliance, and making the knob 160 not scrape against the casing of the cooking appliance when rotating, avoiding the abnormal sound when the knob 160 rotates, ensuring that the stress of the knob 160 is uniform, and prolonging the service life of the electric appliance.
And, after the installation, if the electrical control part has the problem such as slope or off normal because of long-time use, coupling assembling 120 still can utilize the relative activity of first connecting portion 122 and second connecting portion 124, correct it, and then guarantee that knob 160 is still in preset position, reduce cooking utensil's the assembly degree of difficulty, and, make knob 160 when rotatory, can not scrape mutually with cooking utensil's shell, abnormal sound when having avoided knob 160 to rotate, and, guarantee that knob 160's atress 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 to each other, but since the first connection portion 122 and the second connection portion 124 perform relative movement, the direction in which the first connection portion 122 and the second connection portion 124 can move is actually the first direction and the negative first direction.
Specifically, the electrical control may be fixedly connected to the connection assembly 120, for example: clamped, screwed or screwed.
Further, the electrical control component is a printed circuit board, an encoder is welded on the printed circuit board, and a rotating portion 112 is arranged on the encoder.

In this embodiment, on the basis that the first connecting portion 122 can perform relative movement in the first direction, relative movement in the third direction can also be performed, and then the first direction and the third direction perform vector superposition, and the relative movement range of the first connecting portion 122 and the second connecting portion 124 can form a circular area, so that the movement range of the first connecting portion 122 and the second connecting portion 124 is expanded, thereby ensuring that the connecting position between the electric control and the knob 160 can be adjusted by the connecting assembly 120 when the electric control is inclined or deviated in any direction.
Here, it should be noted that the first direction, the second direction and the third direction are vectors, and therefore, it is limited that the third direction is different from and not opposite to the first direction, and the third direction is different from and not opposite to the second direction, but since the first connection portion 122 and the second connection portion 124 perform relative movement, the direction in which the first connection portion 122 and the second connection portion 124 can actually move is 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: a housing and a transmission system arranged at least partially inside the housing, wherein the first connection portion 122 and the second connection portion 124 are both arranged on the transmission system.
In this embodiment, the connecting assembly 120 includes a housing and a transmission system, and the transmission system is partially disposed in the housing, and specifically, the first connecting portion 122 or the second connecting portion 124 can extend out of the housing to facilitate connection with the electrical control and the knob 160, so as to protect the transmission system by the housing, avoid the occurrence of the situation that the transmission system is jammed into a foreign object, and ensure the normal operation of the knob device 100.
Example 4:
