The knob is used as a convenient and simple interaction medium, and functions can be quickly selected and adjusted; direct vision and various handfeel. Therefore, the method is widely applied to household appliances. The knob of magnetism stove is applied to the current, generally beats tightly fixedly through fasteners such as screw, need arrange specific post in assembling process and install the operation, and complex operation is low in complexity, so urgent need a structure of being convenient for install the knob, improve assembly efficiency, simplify the installation operation.
In view of this, the present invention provides a cooking appliance, and fig. 1 to 5 are an embodiment of the cooking appliance provided by the present invention, and the cooking appliance will be described below with reference to specific drawings.
Referring to fig. 1 to 5, the cooking utensil 100 includes a casing 1 and a knob assembly 2, wherein the casing 1 is provided with a relief hole 11; the knob assembly 2 comprises a circuit board 22 arranged in the shell 1 and a knob 21 rotatably arranged on the circuit board 22, and the knob 21 at least partially exposes the abdicating hole 11 for operation of a user; the inside of the housing 1 is provided with a limiting structure 3 at least on two sides of the circuit board 22 in the thickness direction, so as to limit the movement of the circuit board 22.
In the technical scheme of the utility model, knob 21 at least part appears give way hole 11 to for user operation, it can be understood, knob subassembly 2 includes circuit board 22 and knob 21, knob 21 install in circuit board 22, promptly work as circuit board 22 is fixed in when in casing 1, knob subassembly 2 is whole to be fixed in casing 1. Therefore, the limiting structures 3 are arranged inside the housing 1, the limiting structures 3 are arranged on two sides of the circuit board 22 to limit the circuit board 22, and the limiting functions of the limiting structures 3 include not only limiting the displacement of the circuit board 22 along the thickness direction thereof, limiting the displacement of the circuit board 22 along the plane where the circuit board is located, and limiting the rotation of the circuit board 22, so as to fix the circuit board 22. The whole process need not to use fasteners such as screws, only needs the assembly during knob subassembly 2, will circuit board 22 shift to in the casing 1, corresponding to limit structure 3 places, through limit structure 3's spacing, can accomplish circuit board 22's location is fixed, and then accomplishes knob subassembly 2's equipment, convenient operation is efficient.
Specifically, the circumferential side portion of the knob 21 reveals the relief hole 11. The arrangement mode of the knob 21 may be that one end of the knob 21 in the axial direction extends into the housing 1 through the abdicating hole 11 to be mounted on the circuit board 22, at this time, a part of the knob 21 extending into the housing 1 may be a rotating shaft protruding from the knob 21, or may be a body of the knob 21, and only it is ensured that at least a part of the end of the knob 21 in the axial direction is exposed out of the abdicating hole 11 for a user to operate, which is not limited herein; the arrangement of the knob 21 may be such that the radial circumferential side portion of the knob 21 is exposed out of the abdicating hole 11, at this time, the knob 21 is integrally installed inside the casing 1, and only the radial circumferential side portion of the knob 21 extends out of the abdicating hole 11 to the outside of the casing 1. In this embodiment, the mode that the circumferential side portion of the knob 21 in the radial direction is exposed out of the receding hole 11 is adopted, at this time, the knob assembly 2 is integrally installed in the housing 1, that is, both ends of the knob 21 in the axial direction are both limited, so that the installation stability of the knob 21 is ensured, and the situation that in another setting mode of the knob 21, only one end of the knob 21 in the axial direction is limited and installed on the circuit board 22, and the stability is poor is avoided.
In addition, the receding hole 11 is opened on the peripheral side of the housing 1. The arrangement direction of the abdicating hole 11 can be the peripheral side or the top end surface of the shell 1, in this embodiment, the abdicating hole 11 is arranged on the peripheral side of the shell 1, on one hand, the knob 21 is located at the edge of the shell 1 and is far away from the heating panel of the cooking utensil 100, so as to avoid scald caused by accidental touch of human body; on the other hand, the thickness direction of the circuit board 22 is made to be consistent with the thickness direction of the housing 1, so that the influence of the radial size of the knob 21 on the thickness of the housing 1 can be reduced, i.e., when the radius of the knob 21 is set to be larger so as to facilitate operation, the thickness of the housing 1 cannot be increased accordingly.
Specifically, a receiving portion for receiving the circuit board 22 is formed inside the housing 1; the limiting structure 3 comprises a first abutting part 31 and a second abutting part 32 which are arranged in the shell 1 and located on two sides of the circuit board 22, the first abutting part 31 abuts against one side of the circuit board 22, and the second abutting part 32 is opposite to the first abutting part 31 and correspondingly abuts against the other side of the circuit board 22.
