Knob assembly and washing machine applying same
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; and because the rotating shaft occupies a larger space in the knob, a light-emitting structure cannot be added, and only the light-emitting element surrounding the periphery of the knob can be adopted to realize the light-emitting function.
In order to solve the problems, a shaftless encoder can be used for replacing a traditional shaft encoder, but the structure of a 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 fact that the electric control plate has a certain distance with the surface of the shell, and a knob handle for a 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, wherein a hollow assembly structure sleeved layer by layer is adopted, so that the whole weight of the knob is reduced, and meanwhile, a space for additionally arranging a light-emitting structure is provided; meanwhile, the 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 front seam of the knob is reduced, the rotating torque is further increased, and the light leakage of the light-emitting structure can be prevented.
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 piece 4, a shaftless encoder 5, a light guide frame 6, 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 piece 4 and the shaftless encoder 5 are sequentially sleeved layer by layer, so that a cavity for accommodating the light guide frame 6 is formed in the knob assembly.
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 component 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, and compared with the scheme that the shaft encoder is used and only the surrounding light-emitting element is adopted in the prior art, the rotary knob expands the inner space of the knob component, increases the light-emitting area and can realize the rotary knob with the theme light effect. On the other hand, the structure of establishing layer upon layer has further increased the rotation moment, and the user operation of being more convenient for is used.
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 flatly arranged with the outer periphery of the knob body 3, 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, and the knob body 3 is in limit connection with the transmission piece 4 in the axial direction of the knob assembly to form a cavity for accommodating the light guide frame 6; the knob cover 2 is of a light-transmitting structure.
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. And with the spacing installation of driving medium and knob body in the knob axial, make the internal great cavity of formation of knob, can supply to install the great luminous body of area, can attach the printing opacity tectorial membrane on the luminous body, realize showing different patterns on the knob surface. Furthermore, the knob ring is arranged on the periphery of the structural joint of the knob cover and the knob body, so that the light leakage phenomenon can be avoided.
The further scheme of the invention is as follows: the light guide frame 6 comprises a light emitting part 61 arranged at the top of the light guide frame and a support leg 62 extending downwards from the bottom surface of the light emitting part 61, the support leg 62 passes through the shaftless encoder 5 and is clamped with the control circuit board, and a light emitting element electrically connected with the control circuit board is arranged in the light emitting part 61; preferably, the outer circumference of the light emitting portion 61 is slightly smaller than the inner circumference of the knob body 3.
In the scheme, the light-emitting part is of a disc-shaped structure and is accommodated in a cavity defined by the knob cover, the knob body and the transmission part, and the diameter of the disc is slightly smaller than the inner diameter of the knob body, so that the light-emitting area is increased; the transmission part is of a hollow annular structure, and the support legs can pass through the transmission part and the shaftless encoder to be clamped with the control circuit board; and the pins of the light-emitting element in the light-emitting part are electrically connected with the control circuit board through the transmission part and the hollow part of the shaftless encoder.
The further scheme of the invention is as follows: the flange 21 arranged on the outer periphery of the knob cover 2 is in contact with the convex edge 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; 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.
