Detailed description of the invention
This detailed description of the invention provides a kind of knob of washing machine, effectively overcomes knob in prior art and requires great effort and rotate the poor problem of feel.This detailed description of the invention additionally provides a kind of washing machine comprising above-mentioned knob.
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 3, Fig. 3 is knob internal structure schematic diagram in the specific embodiment of the invention.
This detailed description of the invention provides a kind of knob of washing machine, comprises knob body 11, is provided with the inner core 12 that density is greater than the density of knob body 11 in knob body 11.
Setting like this, a part of plastic material of knob body 11 is instead of with inner core 12, density due to inner core 12 is greater than the density of knob body 11, when equal volume, the quality of inner core 12 is greater than the quality of knob body 11, therefore the quality of knob that this detailed description of the invention provides is greater than the quality of knob in prior art, and then the rotary inertia of knob that this detailed description of the invention provides is large compared with the rotary inertia of knob of the prior art, therefore, rotate more laborsaving, the quality of the knob provided due to this detailed description of the invention is larger, effectively improve the rotation feel of knob.
In order to ensure the operating handle of knob, the quality sum of inner core 12 and knob body 11 can be uniformly distributed in the circumference of knob body, certainly, also can make being uniformly distributed in the circumference of knob body 11 qualitatively of inner core 12.
It should be noted that, in this detailed description of the invention, the shape of inner core 12 can comprise semicircular, domain shape, straight bulk, abnormity bulk etc., and the quantity of its inner core 12 can be one also can be multiple.
When the quantity of inner core 12 is one, the shape of inner core 12 is preferably domain shape, and as preferred, the quality of domain shape inner core 12 can be uniformly distributed along the circumference of knob body 11, and so, the rotary inertia of each place value of inner core is equal, and the feel that operates is better.
When the quantity of inner core 12 is multiple, as preferred and citing, the shape of inner core 12 can be arcuation inner core 12, multistage arcuation inner core 12 with the center of rotation of knob body 11 for the center of circle circumferentially intermittently distributes, between two sections of adjacent like this inner cores 12, there is certain distance, while guarantee operating handle, can also material be saved, reduce production cost.
For convenience, the explanation that this detailed description of the invention will be carried out for the inner core of domain shape below, the inner core 12 of domain shape can be quoit, and quoit to be arranged in knob body 11 and coaxially to arrange with knob body 11.
Such as, above-mentioned quoit can be iron ring, copper band, steel ring, aluminium circle or metal alloy circle etc., and quoit and knob body 11 are coaxially arranged, and can make the uniform quality of knob body 11, and then make knob have good texture.
The radius of quoit is larger, and the rotary inertia of knob body 11 is larger, and therefore, in the preferred version of this detailed description of the invention, the radius of quoit can equal 0.5 times of the radius of knob body 11.Setting like this, the radius of quoit is comparatively large, and improve the rotary inertia of knob body 11, rotate more laborsaving, feel is better.
Inner core 12 is set to integral structure by the mode of injection moulding and knob body 11, such as, in the mould of injection moulding knob body 11, puts into inner core 12, then carries out injection moulding, inner core 12 is arranged at the inside of knob body 11 by the mode of injection moulding.
Certainly, also by alternate manner, inner core 12 is arranged at the inside of knob body 11, such as, the draw-in groove of accommodating inner core 12 can be provided with in the inside of knob body 11, inner core 12 is placed in draw-in groove.
In order to improve the aesthetic property of knob, also can be provided with trim 13 in the outside of knob body 11, trim 13 is buckled in knob body 11, effectively improves the aesthetic property of knob.
This detailed description of the invention additionally provides a kind of washing machine, comprises knob as above.Setting like this, the washing machine that this detailed description of the invention provides, its knob is more laborsaving, and the rotation feel of knob is better, and the derivation of the beneficial effect that the derivation of this beneficial effect and above-mentioned knob bring is substantially similar, therefore repeats no more herein.
Above a kind of washing machine provided by the present invention and knob thereof are described in detail, apply specific case herein to set forth principle of the present invention and embodiment, the explanation of above embodiment just understands method of the present invention and core concept thereof for helping.It should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention, can also carry out some improvement and modification to the present invention, these improve and modify and also fall in the protection domain of the claims in the present invention.
