Description
Technical field
The present invention is the invention of relevant washing machine aspect, particularly in the invention of the inner package assembly of the control panel that shows work state of washing machine.
Background technology
The structure of general washing machine has washtub 2 in the inside of washing machine as shown in Figure 1, is provided with top cover 6 above its outer bucket 4, is provided with into the front panel 10 of certain gradient at the rear of top cover 6.When washing machine washed, the user selected the function key of washing according to the requirement of oneself, and above-mentioned front panel 10 is in order to show washing process to the user and to be provided with.
The structure of above-mentioned front panel 10 is illustrated the controller 40 of the control panel installation portion 20 of dress PCB wiring board and the electronic component that is provided with for driving in being disposed with in the front panel 10 with reference to Fig. 2.
On above-mentioned controller installation portion 20, the inside of its shell 21 is provided with for the processing signals that drives washing machine wiring board PCB26, above-mentioned wiring board PCB26 is provided with switch, control panel 22, multiple electronic devices such as rotary switch 24, light-emitting diodes route of pipe line LED, above-mentioned control panel 22 is used for showing work state of washing machine; Above-mentioned rotary switch 24 is according to spinning movement, the function that is marked with for selected above-mentioned control panel 22 and moving hand and the switch base that is provided with makes washing machine carry out work by selected function simultaneously.
The information that shows on the above-mentioned control panel 22 is to inform the user's by the display screen 12 of front panel 10.
With reference to Fig. 2, Fig. 3 above-mentioned control panel 22 is specifically described, be provided with LCD panel LCD22a in control panel shell 22b inside for the signal of display driver washing machine, electronic signal is input among the above-mentioned LCD panel LCD22a, and folding wiring board PCB22c is connected to above-mentioned LCD panel LCD22a.The contact pin of processing signals is installed in above-mentioned folding wiring board PCB22c, and the holding wire that these contact pins form by transfer wire is handled the signal that input is come in, and control LCD panel LCD22a carries out Presentation Function.
LCD panel LCD22a self internal structure is by a pair of sheet glass and space that forms between its sheet glass and liquid crystal, is bonded at the formations such as Polarizer above a pair of sheet glass.Because the formation of this LCD itself is disclosed, directly do not get in touch with the present invention, here just no longer describe in detail.
The downside of LCD panel LCD22a is provided with by reflective and provide the comprehensively uniformly reflective sheeting 22d of illumination to above-mentioned LCD panel LCD22a, and above-mentioned LCD panel LCD22a and reflective sheeting 22d are arranged on the interior upside of control panel shell 22b.Side wall lower ends integrally at control panel shell 22b is formed with insertion pin 22h, and above-mentioned insertion pin 22h supports The whole control panel 22 by among the wiring board PCB26 that is installed in built-in controller adjusting portion 20.
Be stained with many wiring board LED22f to light emitting diode on the bottom surface of above-mentioned control panel shell 22b, this plate is to utilize the adhesive of regulation on control panel shell 22b.
Above-mentioned existing control panel 22 structures have following deficiency:
At first, the wiring board LED22f of light emitting diode utilizes adhesive to be bonded on the lower end of control panel shell 22b, utilize the bonding process of this adhesive to have the low shortcoming of operating efficiency, as it is both time-consuming to smear adhesive, again contaminated environment; Use on the efficient of adhesive to assembling procedure and be subjected to certain restriction, the use adhesive brings the influence to operating ambient temperature on assembling procedure.
In addition, the folding wiring board PCB22c that is connected with the top LCD22a that is bonded at control panel shell 22b is wired on the wiring board PCB26 of control part installation portion 20.Owing to can not connect folding wiring board PCB22c in the inside by above-mentioned control panel shell 22b,, be connected with wiring board PCB26 lead along the back of above-mentioned control panel shell 22b so can only be that above-mentioned folding wiring board PCB22c is folded into after [] shape.The syndeton of this folding wiring board PCB22c is exactly to be in the state that is exposed to control panel shell 22b outside.Therefore, the aqueous vapor contact is in the folding wiring board 22c of exposed state, is just occurring a lot of problems aspect the electrical property easily.Aqueous vapor is impregnated into the inboard of front panel 10, in case contact with above-mentioned folded sheet 22c, will produce the problem of corrosion connecting plate, and, the problems such as processing signals contact pin that are installed on the folded sheet also can appear damaging.In a single day this folded sheet PCB22c damages, and control panel 22 just can not run well, and, cause fatal bad influence substantially also can for the good and bad performance of product.
Summary of the invention
In order to address the above problem, to the objective of the invention is to produce washer control panel, and can prevent because aqueous vapor is impregnated into the problem appearance that inside causes damages such as corroding by simple more assembling procedure.
Technical solution of the present invention provides a kind of package assembly of washing machine display part, comprise the wiring board PCB26 of control panel, folding wiring board 22c, LCD panel LCD22a, the rear wall of control panel shell 30 is provided with the sleeve-board 36 that can insert folding wiring board 22c, described sleeve-board 36 is and 30 one-shot formings of control panel shell, make folding wiring board 22c insert sleeve-board 36 from the top down, and be connected on the printed substrate PCB26 of control panel.
The lower surface 31 of display part shell 30 is provided with paired installation and inserts bearing pin 33, has and insert bearing pin 33 corresponding combined holes 43 on light emitting diode wiring board LED42, inserts bearing pin 33 firm being inserted in the combined hole 43 by the heat seal handle.
Port at the sleeve-board 36 that inserts folding wiring board 22c seals by encapsulant.
Effect of the present invention is not use adhesive the LED substrate junction to be combined on the bottom surface of control panel shell, reduces assembling procedure, the more important thing is that to the working environment that changes original use adhesive also be very favourable.And display part shell back is formed with the sleeve-board that can insert folding wiring board, and this structure has avoided aqueous vapor to be immersed in the problem that occurs on the electrical equipment connecting portion fully.Therefore, can improve the service behaviour of washer control panel.
