Description
Technical field
The utility model relates to household appliance technical fields, in particular for the switch block of household electrical appliance.
Background technique
In the prior art, lighting effects can be added for beauty in many household electrical appliance in operation interface, such as application No. is
The Chinese invention patent of CN201710198335.2 discloses a kind of operation display interface structure of household electrical appliance, including appearance portion
Part, touch key-press and the PCB component on the inside of appearance part are provided with form paster, form paster on the outside of appearance part
On be formed with the content display area at least two intervals, the first perforation corresponding with content display area is offered in appearance part,
Arranged for interval between each first perforation, touch key-press are arranged between form paster and appearance part, and at least and in part
It is corresponding to hold viewing area, PCB component includes at least two LED light corresponding with the first perforation, filled with saturating in each first perforation
The supporting block of light.
After aperture, the periphery in hole is easy to will appear burr appearance part, and the supporting block as light guide is moved during installation
It is easy to be scratched by burr during dynamic positioning, thus usually needs first to handle burr in a pre-installation, otherwise be easy
The phenomenon that now installation is uneven and is scratched, and swarf generation is had in the process of deburring, the production of rear process is made
At adverse effect；Or need that protective case is arranged except supporting block, thus increase component, structure also can be more complicated.
Utility model content
Technical problem to be solved in the utility model is to provide one kind for the above-mentioned problems of the prior art both may be used
To reduce the polishing operation of burr, and it can protect the switch block for household electrical appliance that light guide is not scratched.
Technical solution adopted by the utility model to solve the above technical problems is as follows: it is used for the switch block of household electrical appliance,
Including panel, partially the light guide that is embedded in panel and the bracket that light guide is passed through and fixed for light guide, the panel tool
There is the first burr face, the bracket has the second burr face；It is characterized by: the panel the first burr face and bracket
Two burr faces are oppositely arranged.
Further, the first hole for light guide to be arranged is offered on the panel, corresponding first hole on the bracket
Position offers the second hole for light guide to be arranged, and the first burr face of the panel is located at the periphery in first hole, institute
The the second burr face for stating bracket is located at the periphery in second hole.
Preferably, the light guide is transparent plastic article.
Further, the panel is metal plate decorative panel.
Compared with the prior art, the advantages of the utility model are: by by the of the first burr face of panel and bracket
Two burr faces are oppositely arranged, can protect light guide not by the first burr face of panel and the second burr face of bracket scratch and
It can be reduced the sanding burr process to the first burr face and the second burr face, realize preferable protection effect with less components
Fruit.

Fig. 2 is the local I enlarged drawing of Fig. 1；
Fig. 3 is the side sectional view of the switch block for household electrical appliance of the present embodiment；
Fig. 4 is the local I I enlarged drawing of Fig. 3；
Fig. 5 is the exploded view of the switch block for household electrical appliance of the present embodiment.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Referring to Fig. 1~5, for the switch block of household electrical appliance, including panel 1, it is partially embedded light guide in panel 1
3 and the bracket 2 of light guide 3 is passed through and fixed for light guide 3, button 4 is provided in light guide 3.In the present embodiment, panel 1
For metal plate decorative panel, light guide 3 is transparent plastic article.
The first hole 11 for light guide 3 to be arranged is offered on panel 1, thus in the process that panel 1 opens the first hole 11,
Panel 1 is located at 11 peripheral portion of the first hole and forms the first burr face 12 with burr (only the one side in hole just has)；Bracket 2
The position in upper the first hole of correspondence 11 offers the second hole 21 for light guide 3 to be arranged, and the work in the second hole 21 is thus opened in bracket 2
In sequence, bracket 2 is located at 22 peripheral portion of the second hole and forms the second burr face 22 with burr (only the one side in hole just has).
In order to protect light guide 3 not scratched by the second burr face 22 in the first burr face 12 of panel 1 and bracket 2, and
The sanding burr process to the first burr face 12 and the second burr face 22 is reduced, in the present embodiment, by the first burr of panel 1
Face 12 and the second burr face 22 of bracket 2 are oppositely arranged.It is installed on panel 1 and bracket 2 when by light guide 3 as a result, light guide
3 during running fix, all will not directly contact with two burr faces, the face after being punched so as to avoid light guide 3
Burr on plate 1 and bracket 2 scratches.
This setup does not both have in advance polish to burr face, and without other setting protective case, process is few,
Component is few, and protecting effect is good.
