Abstract
A liquid crystal display screen (LCD) component of washer consists of rectangular insulation board, printed circuit, and LCD. It is featured as having connection boss and support rib on rectangular insulation board for fixing or supporting LCD, setting printed circuit in edge frame of the insulation board, coating an insulating layer on outer side of printed circuit and presenting as '7'-shape by overlooking the supporting rib.
Description
Technical field
The present invention relates to washing machine, particularly the package assembly of the LCDs on the washer control panel (LCD) assembly.
Background technology
The cutaway view of the internal structure of the existing washing machine of Fig. 1.As shown in Figure 1, existing washing machine is that the compound action of emulsification and the impeller 1 (and washtub 2) of a kind of frictional force by washing current and locker room, washing agent impulsive force that clothing is applied is separated the tame electric machine attached to the dirt on the clothing.
In above-mentioned existing washing machine, control panel is to be used for carrying out the parts of controlling the various operations of washing machine and exchanging mutually with the user.Fig. 2 is the structural representation of use in washing machine control panel shown in Figure 1.
As shown in Figure 2, the control panel 3 of existing washing machine comprises: be used for showing work state of washing machine display screen 3c, be used for selecting several buttons 3b and the printed circuit-board assembly of washer operation order.
In recent years, the general trend that adopts the LCDs (LCD) 4 of the multiple information such as work at present state that show selected function of user and washing machine of described display screen 3c capable of washingly.
Fig. 3 is along the profile of I-I line among Fig. 2; Fig. 4 is the fixed structure schematic diagram of the LCDs (LCD) above the insulation board shown in Figure 3.
As shown in Figure 3 and Figure 4, the outward appearance of described LCDs (LCD) assembly is rectangular tabular, insulation board 5 is positioned at foot, be formed with the frame 500 that raises up in the edge of insulation board 5, be inserted with printed circuit board (PCB) 6 in the frame 500, the upper surface of printed circuit board (PCB) 6 is coated with the insulating barrier 7 that one deck is used for insulating.
In addition, described insulation board 5 is provided with 4 and is used for LCDs (LCD) 4 is fixed to connection boss 520 on the insulation board 5.
Described connection boss 520 is fixed on LCDs (LCD) 4 on the insulation board 5 with screw respectively and makes the insulating barrier 7 on LCDs (LCD) 4 and the insulation board 5 keep certain intervals.
But there is shortcoming in the LCDs of above-mentioned existing washing machine (LCD) assembly package assembly:
Owing to keep certain interval between the insulating barrier 7 on LCDs (LCD) 4 and the insulation board 5, thereby the central portion of working as LCDs (LCD) 4 is done the time spent for being under pressure, LCDs (LCD) itself can occur bending and deformation, and causes the screw connection portion position of LCDs (LCD) 4 to take place damaged.
Summary of the invention
Technical problem to be solved by this invention is, overcome the shortcoming of LCDs (LCD) the assembly package assembly of above-mentioned existing washing machine, even a kind of LCDs (LCD) effect of being under pressure is provided, the package assembly of LCDs (LCD) assembly that LCDs (LCD) itself can diastrophic washing machine yet.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: the package assembly of the LCDs of washing machine of the present invention (LCD) assembly comprises: rectangle insulation board, printed circuit board (PCB) and LCDs (LCD); The edge of described rectangle insulation board is formed with the frame of downward protrusion, and the upper surface of rectangle insulation board is formed with several ribs that is used for being connected and fixed connection boss He several pressure support LCDs (LCD) of LCDs (LCD).
Be provided with printed circuit board (PCB) in the frame of described insulation board, described printed circuit board (PCB) outer surface coating is formed with a layer insulating.
Described upper surface at insulation board protrudes on the connection boss that forms and is formed with screw hole, utilizes screw that LCDs (LCD) is fastened on and connects on the boss.
Described ribs is overlooked and is " " font when observing.
The invention has the beneficial effects as follows: simple in structure, easy to assembly; Even at the central portion of LCDs (LCD) 4 for exerting pressure, because the supporting role of " " font 510 pairs of LCDs of ribs (LCD) bottom surface of insulation board 5 upper surfaces, LCDs (LCD) 4 phenomenon that also can not occur bending and deformation itself, thus the screw connection portion position that prevents LCDs (LCD) 4 takes place damaged.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Fig. 5 is the sectional structure schematic diagram of LCDs of the present invention (LCD) assembly; Fig. 6 is the fixed structure schematic diagram of the LCDs (LCD) above the described insulation board of Fig. 5.
As shown in Figure 5 and Figure 6, present embodiment LCDs (LCD) assembly comprises: rectangle insulation board 5, printed circuit board (PCB) 6 and LCDs (LCD) 4; The edge of described rectangle insulation board 5 is formed with the frame 500 of downward protrusion, and the upper surface of rectangle insulation board 5 is formed with several and is used for being connected and fixed the connection boss 520 of LCDs (LCD) 4 and the ribs 510 of several pressure support LCDs (LCD) 4.
Be provided with printed circuit board (PCB) 6 in the frame 500 of described insulation board 5, described printed circuit board (PCB) 6 outer surfaces coating is formed with a layer insulating 7.
Described upper surface at insulation board 5 protrudes on the connection boss 520 that forms and is formed with screw hole, utilizes screw that LCDs (LCD) 4 is fastened on and connects on the boss 520.
Described ribs 510 is overlooked and is " " font when observing.
Below present embodiment LCDs (LCD) assembly assembling process and effect are illustrated:
During assembling display screen (LCD) assembly, at first LCDs (LCD) 4 is placed on rectangle insulation board 5 above, and printed circuit board (PCB) 6 is set in the frame below insulation board 5 500, make screw hole on LCDs (LCD) 4 and the printed circuit board (PCB) 6 aim at screw hole on the corresponding connection boss 520 on the rectangle insulation board 5 respectively, with screw LCDs (LCD) 4 and printed circuit board (PCB) 6 are fastened on the rectangle insulation board 5 respectively then, at this moment, " " font 510 pairs of LCDs of ribs (LCD) 4 of the upper surface of rectangle insulation board 5 protrusion formation are played a supporting role; The outer surface of last printed circuit board (PCB) 6 applies a layer insulating 7.
Assemble display screen (LCD) assembly that finishes according to said structure, even at the central portion of LCDs (LCD) 4 for exerting pressure, because the supporting role of " " font 510 pairs of LCDs of ribs (LCD) bottom surface of insulation board 5 upper surfaces, LCDs (LCD) 4 phenomenon that also can not occur bending and deformation itself, thus the screw connection portion position that prevents LCDs (LCD) 4 takes place damaged.
