When transparent box 48 is assembled on the control device 41, because its bottom surface is provided with breach 48b, therefore and leave the gap between the control device 41, in the table that damp proof embedding agent 46 is injected into control device 41 during the two sides, damp proof embedding agent 46 can promptly flow in the transparent box 48.Like this, damp proof embedding agent 46 can flow in the coupling part of the liquid crystal display 38 that is contained in transparent box 48 inside and control device 41, not only can improve the quality of products, and can also reduce flow chart simultaneously.
In addition, one or several diameters are set on the part side of the transparent box 48 that liquid crystal display 38 is covered fully are after the aperture 48c about 0.8mm, cover the outside of transparent box 48 of liquid crystal display 38 and inboard air pressure identical.Like this, the situation that dewfall takes place on the inner surface of transparent box 48 can be inhibited, and not only can eliminate diminishing fog attractive in appearance, can also prevent that liquid crystal display 38 from absorbing aqueous vapors, phenomenon such as insulation degradation occurring simultaneously.
In addition, owing to the panel paster hole 29 on the panel paster 30 of the end face that covers the display part 32 in the operation display panel 31 is arranged to bigger than the profile of the transparent box 48 that covers liquid crystal display 38 fully, therefore, even, also can not diminish the aesthetic property of product because of the error or the part dimension error of assembling causes transparent box 48 to exceed display part 32 on the operation display panel 31.In addition, because panel paster 30 is provided with panel paster hole 29, so the top of liquid crystal display 38 will have only transparency window 43 these two kinds of parts of transparent box 48 and panel cover 20, visuality also will be improved.
In addition, by groove 49 is set around the display part 32 of operation display panel 31 and operation push-button 35, the convex tendon 50 that protrudes downwards is set on the back side of panel cover 20 and groove 49 corresponding positions, form convex tendon 50 and extend into structure in the groove 49, the water of invading from the gap between panel cover 20 and the operation display panel 31 is flow in the groove 49 on the operation display panel 31.Like this, the situation that water droplet attaches on the panel paster 30 of the upper surface that covers display part 32 just can be prevented, and panel paster 30 is peeled off, diminished situation such as attractive in appearance and also can be prevented.
In addition, because the panel box in the operation display device of the present invention is provided with through hole, even so exceed under the situation of operation display panel at the display box that is prone to, the surface of panel paster seems also not seem rough and uneven in surface, and does not worry having in the adhesive portion situations such as water and dust stockpile, occur peeling off.In addition, situation also can not occur dewfall to take place, cause that the user worries on the surface of liquid crystal display etc., thereby the reliability of liquid crystal display is improved.
Though the above embodiments have just been mentioned washing machine, the electrical equipment for using liquid crystal display adopts the words of equal formation just can obtain equal effect.This is self-evident.
In sum, even operation display device of the present invention is under more that see, the situation that display box exceeds operation display panel of existing apparatus, the surface of sticking panel paster rear board paster can not seem rough and uneven in surface yet, do not worry having in the adhesive portion water and dust to stockpile, occur peeling off, the situation that occur dewfall on the surface of liquid crystal, the user is worried can not occur yet yet.And, even there is water to invade from the outside, water also can not be seeped into the panel paster upper surface, situations such as attractive in appearance appear diminishing.The present invention can improve the reliability of liquid crystal display, so go for being provided with in the various appliance arrangements of operation part and display unit.
