Embodiment
Before enforcement example of the present invention is described, in the inscape of the present invention with original consistent part, with reference to Fig. 1 and Fig. 3, give identical title and label.
Shown in Fig. 4,5, in general, upper end, the front of drying machine body 1 is the control panel (control panel) 10 that has operating knob 11 and display window (display windows) 12.Wherein, operating knob 11 has several, and the user can carry out energized etc. in interior various operations by it; Display window 12 then can be used for showing various information such as the running status of the selected function of user, dryer and abnormal conditions.
The aforesaid operations button can be selected push type push button (push type button is to call " button " in the following text) or knob for use.Wherein button is by pressing button, exerts pressure for the contact witch (tactswitch) that is installed in the button rear, thereby carries out interim function selecting.And knob is by turning knob framework and rotary body (rotary volume), selects needed process.
Installed in the inside of above-mentioned control panel 10 and to have comprised the circuit that drives dryer and the pcb board 21,22 of other various electric elements.And pcb board 21,22 can show PCB21 and control PCB22 to be divided into.Wherein, show that PCB21 by switch and LED (Light Emitting Diode, light-emitting diode), line segment (segment) electric elements of etc.ing, carries out and the I/O function associated of passing through control panel; Control PCB22 carries out the running/control function associated with dryer by various transducers and microcomputer etc.
The back of above-mentioned demonstration PCB21 will connect and show insulation board 131.At this moment, in order to make the various elements that are connected on the above-mentioned demonstration PCB21 corresponding with appropriate operating knob 11 and display window 12 on the above-mentioned control panel 10, the front of above-mentioned demonstration PCB21 will be fixed with the back side of above-mentioned control panel 10 is corresponding.
Above-mentioned control PCB22 will be connected to its back side on the above-mentioned control insulation board 132, so that make the back side of above-mentioned control insulation board 132 relative with the back side of above-mentioned control panel 10, promptly will allow the front of above-mentioned control PCB22 facing to the internal direction of dryer.
In addition, above-mentioned demonstration PCB21 will be connected by the lead-in 23 of drawing from the various elements of above-mentioned demonstration PCB21 with control PCB22.
A side (being the right side among the figure) will be drawn and focus on to above-mentioned lead-in 23 from each element of the front that is installed on above-mentioned demonstration PCB21, and after the above-mentioned lead-in 23 that puts together will wale with other hoop line mode (wire ferrule or insulating tape etc.), be connected on the link of above-mentioned control PCB22.
Certain position in whole outsides of above-mentioned each insulation board 131,132 has formed some each connecting portions 133 that protrude laterally, then formed on the connecting portion 133 will with can be connected to the connecting hole that the connecting screw 133a on the above-mentioned control panel 10 is connected to above-mentioned insulation board 131,132.
Here, because protruding with certain altitude, above-mentioned connecting portion 133 forms, so when being connected to above-mentioned demonstration insulation board 131 on the above-mentioned control panel 10, between the medial surface lower end of the lower end of above-mentioned demonstration insulation board 131 and above-mentioned control panel 10, will form the identical excess room of height with the connecting portion 133 of the lower end that is positioned at above-mentioned demonstration insulation board 131.
Above-mentioned line built-in beam (rib) 134 will be on the Width of the downside end of above-mentioned demonstration insulation board 131, is protruded with relative direction across a certain distance mutually by the needle beam of 2 L-shaped shapes to form.
Be after above-mentioned line built-in beam 134a, 134b want earlier the distance identical with the length of the connecting portion 133 of the lower end that is positioned at above-mentioned demonstration insulation board 131 of prolongation downwards, prolong the identical distance of width with the downside of above-mentioned demonstration insulation board 131 to Width again, thereby form " L " shape.
The lead-in 23 of drawing from above-mentioned demonstration PCB21 is from the extracting previously of above-mentioned demonstration PCB21, guides to a side of above-mentioned demonstration insulation board 131, and it is bound round, and is introduced to the back again below above-mentioned demonstration insulation board 131 afterwards.
When above-mentioned lead-in 23 is guided to the lower end of above-mentioned demonstration insulation board 131, will be inserted between 2 line built-in beam 134a, the 134b on above-mentioned demonstration insulation board 131 right sides fixingly, the one end can be introduced on the above-mentioned control PCB22 on the right side that is positioned at above-mentioned demonstration PCB21 then.
Like this, above-mentioned control panel 10 just will be assembled on the above-mentioned drying machine body 1 under the state above-mentioned lead-in 23 is fixed on the space of lower end of above-mentioned demonstration insulation board 131 and control panel 10 by above-mentioned line built-in beam 134 in.Therefore, just prevented that above-mentioned lead-in 23 is snapped to the situation between above-mentioned control panel 10 and other the inner parts.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment did.
Moreover, this PCB is fixing also can be applicable to other household appliances as washing machine etc. that need fix the line of pcb board and pcb board except dryer with insulation board.This point also is conspicuous.
PCB of the present invention is fixing to have following effect with insulation board:
1, is positioned at the line built-in beam of fixing the insulation board lower end that shows PCB because of the lead-in of drawing and fixes, so the phenomenon of interference can not occur producing between the parts such as above-mentioned lead-in and control panel and body casing from demonstration PCB.
2, because above-mentioned lead-in is put in the space of control panel and insulation board lower end, so above-mentioned lead-in is stuck in the phenomenon that is damaged between each parts can prevent that control panel is assembled into the body casing time.
3, because control panel will be assembled on the body under the simply and stably fixing state of the line built-in beam that above-mentioned lead-in is positioned at above-mentioned demonstration insulation board lower end, so when assembling, needn't consider issuable interference between above-mentioned lead-in and other parts.Therefore assembling process is simple, and packaging efficiency improves, thereby shortens built-up time.
