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 the user operation panel becomes more and more simplified, the early multiple operation knobs gradually change into the structures of the knobs and the simple case matching panel for displaying, the number of the knobs is reduced, the number of the corresponding selection functions of the knobs is increased, and the use frequency of the knobs is increased. The existing belt shaft encoder has the problems of large program selection span interval, large noise, large resistance and poorer rotary hand feeling.
In order to solve the problem, a shaftless encoder can be adopted to replace the traditional shaft encoder, but the structure of the knob corresponding to the shaftless encoder is complex, and a transmission part connected with the encoder is often required to be arranged due to the certain distance between the electric control plate and the surface of the shell, and a knob handle for the user to rotate is additionally arranged on the basis. At this time, if the 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 shaft-free encoder has the problem of labor-consuming rotation due to the large diameter.
In view of the above, the present invention is particularly proposed.
Disclosure of Invention
The technical problem to be solved by the invention is to overcome the defects of the prior art and provide a knob assembly, and the whole weight of the knob is reduced by adopting a hollow assembly structure sleeved layer by layer; meanwhile, the ring body structure for fixing the knob cover and the knob body is additionally arranged at the position of the knob cover and the knob body, so that the front seam of the knob is reduced, and meanwhile, the rotating torque is further increased, and the rotation is more labor-saving.
In order to solve the technical problems, the invention adopts the technical scheme that:
the invention provides a knob assembly which comprises a knob body 3, a transmission part 4 and a shaftless encoder 5 which are coaxially arranged, and further comprises a knob cover 2 and a knob ring 1 for hooping the knob cover 2 on the top surface of the knob body 3, wherein the knob ring 1, the knob body 3, the transmission part 4 and the shaftless encoder 5 are sequentially sleeved layer by layer, so that the connection structure on the circumferential direction of the knob assembly is matched and hidden.
In the above scheme, the shaftless encoder is a standard part, is installed on the control circuit board, is a hollow inner and outer two-layer structure, and the outer layer is a rotatable outer ring, and the rotation of this outer ring can produce the signal of telecommunication and select the operational mode, and the inlayer is the immovable inner circle. In order to enable the outer ring of the shaftless encoder to rotate, the hollow knob assembly sleeved layer by layer is arranged, on one hand, the total weight of the knob can be reduced, the rotation is more labor-saving, on the other hand, a cavity is generated in the knob, the light-emitting structure can be additionally arranged, on the other hand, the structure sleeved layer by layer further increases the rotation torque, and the operation and the use of a user are more convenient. In addition, because the connecting structure is arranged on the circumferential direction of the knob component, the connecting structure can be hidden in the knob component after assembly, and the assembly structure is protected from dirt.
The further scheme of the invention is as follows: the knob subassembly is equipped with guide structure and joint structure in the interval in the week, makes the knob subassembly that successive layer cover was established cooperate the connection.
In the above scheme, guide structure includes guide post and guide way, the direction that sets up of guide post and guide way parallels with the axial of knob subassembly to interval distribution is in the week of each subassembly of knob, and the joint structure includes jack catch and draw-in groove, and guide structure and joint structure interval set up, can further increase the assembly fastness between the knob subassembly, make the knob structural installation inseparable, can realize light and handy smooth-going rotation, noise when having eliminated the rotation. Because the jack catch in the joint structure is comparatively complicated, difficult shaping, consequently preferably sets up the jack catch structure on the outer peripheral face of each subassembly.
The further scheme of the invention is as follows: the knob cover 2 is horizontally arranged with the outer periphery of the knob body 3, and the inner periphery of the knob ring 1 is respectively matched and connected with the outer peripheries of the knob cover 2 and the knob body 3.
In the above scheme, due to the technical scheme that the knob cover and the knob body are clamped from the side face, the technical scheme is different from the scheme that the knob cover is clamped into the top face of the knob body in the prior art, and the knob cover with the periphery flush with the knob body is adopted, so that the structural seam of the top face of the knob (namely the top face of the knob cover) can be moved to the periphery of the knob, and the water drops on the surface of the knob are prevented from leaking into the inside of the knob.
The further scheme of the invention is as follows: the flange 21 arranged on the outer periphery of the knob cover 2 is contacted with the flange 13 on the top of the inner periphery of the knob ring 1 for limiting, and the knob cover 2 is pressed on the top of the knob body 3.
In the above scheme, the flange is arranged near the bottom of the outer periphery of the knob cover, so that the outer periphery of the knob cover forms a step-shaped structure along the radial section, the top of the inner periphery of the flange extends towards the geometric center of the knob ring and is overlapped on the flange to form the contact limit of the flange to the flange, and the knob cover is pressed on the knob body.
The further scheme of the invention is as follows: the top of the periphery of the knob body 3 is convexly provided with a first claw 31 and a first guide post 32 which are distributed at intervals and are matched and connected with the first clamping groove 11 and the first guide groove 12 which are arranged on the inner side of the knob ring 1.
In the above scheme, because the knob circle surrounds the fastening to the periphery formation of knob body and knob lid, and the knob lid has certain thickness, consequently sets up guide structure and the joint structure that corresponds the interior circumference of knob circle in the top periphery of the knob body to the thickness of further control knob circle, connect the dynamics that compresses tightly to the knob lid of further increase knob circle chimb through the cooperation of knob circle and knob body simultaneously, make the structure assembly more firm.
