Description
Technical Field
The invention belongs to the technical field of household appliances, and particularly relates to a knob assembly and a washing machine using the same.
Background
With the development of household appliance technology, the logic of a user operation panel becomes more and more simplified, a plurality of operation knobs at early stage are gradually changed into structures of knob and simple case cooperation panel display, and the reduction of the number of the knobs also enables the number of corresponding selection functions of the knobs to be increased, and the use frequency of the knobs to be high. The existing shaft encoder has the problems of large program selection span, large noise, large resistance and poor rotating hand feeling.
In order to solve the problem, a shaftless encoder can be adopted to replace the traditional shaftless encoder, but the knob structure corresponding to the shaftless encoder is complex, and because the electric control plate is a certain distance from the surface of the shell, a transmission piece connected with the encoder is often required to be arranged, and a knob handle for a user to rotate is additionally arranged on the basis. If a knob cover is attached to the top surface of the knob cover, the connection gap between the knob cover and the knob body is large, so that the installation is unstable. Meanwhile, the shaftless encoder has a large diameter and also has the problem of labor-consuming rotation.
In view of this, the present invention has been made.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects in the prior art, and provide a knob assembly which adopts a hollow assembly structure sleeved layer by layer, thereby reducing the overall weight of the knob; meanwhile, a ring body structure for fixing the knob cover and the knob body is additionally arranged at the knob cover and the knob body, so that the rotary moment is further increased while the front seam of the knob is reduced, and the rotation is more labor-saving.
In order to solve the technical problems, the invention adopts the basic conception of the technical scheme that:
the invention provides a knob assembly, which comprises a knob body 3, a transmission piece 4 and a shaftless encoder 5 which are coaxially arranged, and also comprises a knob cover 2 and a knob ring 1 which hoops the knob cover 2 on the top surface of the knob body 3, wherein the knob ring 1, the knob body 3, the transmission piece 4 and the shaftless encoder 5 are sequentially sleeved layer by layer, so that the connection structure in the circumferential direction of the knob assembly is matched and hidden.
In the scheme, the shaftless encoder is a standard component, is arranged on the control circuit board, is of a hollow inner-outer two-layer structure, is provided with a rotatable outer ring, can generate an electric signal through rotation of the outer ring and selects an operation mode, and is provided with a fixed inner ring. In order to rotate the outer ring of the shaftless encoder, the hollow knob assembly sleeved layer by layer is arranged, so that the total weight of the knob can be reduced, the rotation is more labor-saving, a cavity is formed in the knob, a luminous structure can be additionally arranged, and the rotating moment is further increased due to the layer by layer sleeved structure, so that the rotary knob is more convenient for a user to operate and use. In addition, because the connecting structure is arranged on the circumference of the knob assembly, the connecting mechanism can be hidden inside the knob assembly after assembly, so that the assembly structure is protected from dirt accumulation.
The invention further provides the following scheme: the knob assembly is circumferentially provided with guide structures and clamping structures at intervals, so that the knob assemblies sleeved layer by layer are matched and connected.
In the above-mentioned scheme, guide structure includes guide post and guide way, the setting direction of guide post and guide way is parallel with the axial of knob subassembly to the interval distribution is in the circumference of each subassembly of knob, and the joint structure includes jack catch and draw-in groove, and guide structure and joint structure interval setting can further increase the assembly fastness between the knob subassembly, makes knob structure installation inseparable, can realize light and handy smooth rotation, has eliminated the noise when rotating. Since the claws in the clamping structure are complex and difficult to mold, the claw structure is preferably arranged on the outer peripheral surface of each component.
