Description
Technical field
The utility model relates to the waterproof construction of a kind of impeller-type or stirring type fully-automatic washing machine Computerized controller, especially this controller; In International Patent Classification (IPC), can belong to D06F37/26.
Background technology
For impeller-type or stirring-type computer control automatic washing machine, how to prevent the infringement of sealing to the circuit of its Computerized controller, be the improved problem of seek assiduously in the industry always.In these present washing machines, traditional Computerized controller normally welds display device, button and other electrical and electronic component and forms on printed circuit board (PCB), be mounted on the bottom side of the guidance panel of washing machine.For display interface that upwards manifests display device and the operating surface that touches button, the guidance panel of washing machine is opened suitable hole in the display interface of display device and the operating surface of button over against part, pasting in its end face then can be in the decoration glued membrane of the operating surface of the display interface of relevant position see-through display part and indication button, and mainly relies on the buffer action of this decorations glued membrane to prevent that sealing invades from top to bottom.But this decoration glued membrane exists always and is difficult to improved problem in mounting process reliability and service life etc.Most traditional Computerized controllers also carry out sealing to printed circuit board (PCB) together with electrical and electronic component, and except that improving the protection against the tide, main is to prevent to cause electrical fire when bad generation is intake because the decoration glued membrane is isolated.But this technology is cumbersome, and influences maintenance and increased cost.In addition when mounted, the hole that open the guidance panel relevant position need be aimed at or pass through to the display interface of the display device of tradition Computerized controller and the operating surface of button, these holes need be aimed at again and decorate corresponding perspective of glued membrane or indicating positions, have the consistent technology controlling and process problem in location.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of impeller-type or stirring type fully-automatic washing machine Computerized controller are provided, it can overcome the deficiency of traditional product, especially need not rely on the waterproof measure on the washing machine, and helps installing on washing machine and reducing the cost.
The technical scheme that the utility model solve the technical problem is that a kind of impeller-type or stirring type fully-automatic washing machine Computerized controller comprise printed circuit board (PCB) and go up display device, button and other electrical and electronic component that connects, and fixed installation portion; It is characterized in that: also comprise a loam cake, it is positioned at the top of printed circuit board (PCB), except that the display interface that manifests display device and can touching the operating surface of button, hides printed circuit board (PCB) downwards and goes up the electrical and electronic component remainder that connects.
This loam cake can be when decorating glued membrane and in a single day lost efficacy, the water retaining that falls printed circuit board (PCB) and on outside the electrical and electronic component of connection.This design is transferred to prior art on the Computerized controller at the waterproof measure of implementing on the washing machine usually dexterously and implements, but latter's globality is strongly professional, design and installation can be more simple and reliable, especially can reduce decorating the requirement of glued membrane and installation thereof, and because waterproof is reliable, can be coated with damp-proof paint and replace sealing, can be significantly reduced to originally and convenient for maintaining.Because this design, be display interface that appears display device and the required perforate of operating surface that touches button on the washer operation panel, can be designed to surround a macropore of the operating surface of the display interface of these display devices and button, thereby overcome the installation orientation problem of traditional product.
One of further design of the technical scheme that the utility model solve the technical problem is, is placed on the perforate of display device place on described, and display device hides this hole or is connected with this hole is airtight; And the boss of periphery for making progress of the described perforate of preferably further design, the periphery of described display device is the shirt rim of the described boss of encirclement.Can certainly design described loam cake is transparent in display device display interface place.Use transparent configuration can exempt the problem that bring perforate or location.
Two of the further design of the technical scheme that the utility model solve the technical problem is, the operation part of described button is "T"-shaped, is placed on the perforate of button place on described, and this perforate is that the "T"-shaped bar portion of described button passes through with cap portion and hides; And the boss of periphery for making progress of the described perforate of preferably further design, the periphery of the cap portion that described button is "T"-shaped is the shirt rim of the described boss of encirclement.
Constitute maze path around the boss of loam cake perforate and the shirt rim of display device or button cap portion, can prevent effectively that the ponding of loam cake from flowing to described perforate; It further designs is that these boss down lead to the path of loam cake periphery around level or inclination, so that ponding is drained toward the periphery of loam cake.
Three of the further design of the technical scheme that the utility model solve the technical problem is, also comprise an end box, be positioned at the below of described loam cake, and to engage with described loam cake be a cavity volume, hold described printed circuit board (PCB) and go up the electrical and electronic component remainder that connects; And the preferably further lowest part perforate of design box of the described end, be beneficial to get rid of and leak unexpectedly.This perforate is preferably lateral openings.This end box structure can prevent the harm that dabbles from the below.
