Description
Technical field
The present invention relates to a kind of washing machine key-press, especially a kind of key water-proof structure of washing machine.
Background technology
Promptly the computer plate below the guidance panel of washing machine, because washing machine often is to use in the bigger environment of humidity, the computer plate causes short circuit because of water inlet and the phenomenon of burning often occurs, if do not consider waterproof, water can be from the key hole on the decorative panel, directly penetrate on the computer plate, cause the computer plate to have the hidden danger of making moist and damaging.Traditional washing machine, panel control box are the modes that adopts the mechanical type button, and shortcoming is to cause the bad or overlong time button damage afterwards by bonding force easily, causes market bad, increases the quality maintenance cost; The structure of simultaneously traditional washer control panel adopts the separate mechanical combining structure, and assembling and water proofing property are poor.
In order to prevent to be positioned at the computer plate water inlet of washer operation panel below, thereby reduction mass loss, common solution is the computer plate to be carried out encapsulating handle or use the nylon film water proof at present, previous solution can reduce production efficiency and production cost is significantly improved, the latter is the forming materials difficulty then, the hardness height, the button feel is very poor.
Application number is that 200520139513.7 Chinese patent discloses a kind of capacitor induction type button washing machine, it is poor that it has solved traditional washing machine mechanical type key mode assembling, the problem that causes or overlong time afterwards button damage and water proofing property difference bad easily by bonding force, provide a kind of easy for installation, safe and reliable, assembling and the good capacitor induction type button washing machine of water resistance; Capacitor induction type button washing machine of the present utility model includes casing, is installed in control panel, transmission system and culvert system on the casing, control panel includes key-press module and panel itself, key-press module is the capacitor induction type module, and key-press module and panel itself are integrated.So the said structure material is owing to key-press module and the integrated difficult forming of panel itself, and the hardness height, the button feel is very poor.
Application number is the waterproof construction that 02248031.5 Chinese patent discloses a kind of washing machine push-button switch, has the switch assembly that cover is covered with the pushing mechanism of button cap and is fixed in washing machine control console; It is characterized in that: washing machine control console has a continuous installed surface; Described waterproof construction also comprises the sealing shroud that elastomeric material is made, and its top wraps button cap, and its bottom is continuous shirt rim, and fits in the continuous installed surface of washing machine control console.This structure is used for a long time, and the sealing shroud that elastomeric material is made can be out of shape, because water is stored in the space, can slowly infiltrate, and waterproof effect is bad, and water is stored in easy breed bacteria in the key hole space for a long time.
In view of this special proposition the present invention.
