Now retrieve the control panel structure that one section of application number is the patent document washing machine of China's announcement of 200410020002.3, recording control panel in the description of this patent document comprises by cover plate, being positioned on the downside of cover plate and being led by the shell that cover plate covers, the printed circuit board (PCB) being arranged on shell guiding inner is formed.

Detent mechanism is lacked in the mounting structure that above-mentioned patent document does not lead to cover plate and shell, easily the phenomenon misplaced is there is between the cover plate of installation and shell lead, cause cover plate and shell lead between there is gap, make liquid flow into shell guiding inner, cause the disastrous effect that printed circuit board (PCB) damages.

This patent document produces for above-mentioned technical problem.

Utility model content

For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of housing with the control panel of good water resistance.

For achieving the above object, the utility model provides following technical scheme:

A housing for control panel, is characterized in that, comprises rectangular-shaped cover plate, described cover plate four edge is equipped with side plate, the end face of side plate is provided with the locating piece of protruding " L " shape, and described locating piece is placed in the intersection of adjacent side plates, and the both ends of described locating piece all offer scarf.

By adopting technique scheme, the side plate at rectangle cover plate and its four edge forms a rectangular-shaped housing, and housing is placed on outside printed circuit and forms bucker.The corner place of housing is equipped with locating piece, and this housing is rectangle, more accurate housing can be positioned drain pan, prevent housing relative to drain pan generation arranged in dislocation, improve the water resistance of housing by location, corner.The object of locating piece is designed to " L " shape is, locating piece is arranged along the end face of adjacent side plates, locating piece tool and the drain pan of " L " shape have larger contact surface, after locating piece abuts with drain pan, can cross make shell stability be fixed on drain pan, prevent housing because position skew occurs in shake, improve the water resistance of housing.The end of locating piece adopts the advantage of scarf to be, during pressing housing, when scarf extruding drain pan makes case material be out of shape, makes the junction of scarf have better sealing property, improves the water resistance of housing.

Preferably, described scarf is curved surface protruding outside described end.

By adopting technique scheme, increasing the contact area of scarf, making liquid more be difficult to infiltrate printed circuit from the junction of scarf.

Preferably, the first surface that described cover plate is provided with side plate is fixed with several joint pins, described company

The one end connecing post is coniform.

By adopting technique scheme, first surface is fixed in joint pin one end, and the other end is plugged in the connecting hole of circuit board, glutinous agent can be placed in connecting hole, after joint pin inserts connecting hole, the glutinous agent generation deformation in its connecting hole, make joint pin card and connecting hole, realize the fixing of housing and circuit board.Cone shape advantage is to make joint pin be more prone to slip into connecting hole, connects more quick.

Preferably, stiffener muscle is provided with between described joint pin and cover plate.

By adopting technique scheme, stiffener muscle adds the structural strength of joint pin, decrease the possibility that joint pin fractures because of external force, the structure enhancing of joint pin simultaneously makes the connection of housing and drain pan more stable, prevents the situation causing housing to depart from drain pan because joint pin fractures from occurring.

Preferably, the quantity of described stiffener muscle is three.

By adopting technique scheme, three stiffener muscle are surrounded on joint pin and arrange, utilize triangle to have the specific of stability, add the lifting of stiffener muscle to joint pin steadiness and prevent the situation causing because joint pin fractures housing to depart from drain pan from occurring, improve the water resistance of housing.

Preferably, the second surface of described cover plate is provided with LED display window, and the opening of described display window diminishes to first surface gradually from second surface.

By adopting technique scheme, wherein LED is placed in first surface, and the opening of display window has disperse function to arranging of diminishing gradually of first surface to the light of the generation of LED from second surface, enhances the sense organ intensity of human body eye to LED lamplight.Further, the display window that opening is obliquely installed, makes water droplet not easily accumulate, and the situation effectively avoiding water droplet to infiltrate printed circuit board (PCB) from display window occurs, and improves the water resistance of housing.

The operation principle of this case: locating piece is set at the side board edge of housing, prevent from housing from dislocation being installed to cause, gap is there is between housing and drain pan, water is made to enter printed circuit board (PCB), and the contact surface of locating piece and drain pan is improved, is tilting curved surface, increase locating piece and the contact surface at the bottom of shell, make shipwreck to infiltrate printed circuit board (PCB), effectively improving can the water resistance of housing of control panel.
