Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing machine in which a main body is provided with a washing tub and a driving operation portion is provided on the upper part of the main body. More specifically, the washing tub is an outer tub suspended and supported in the main body. The present invention relates to a washing machine such as a fully automatic washing machine having a dehydration and washing tub rotatably supported in the outer tub and a driving operation unit provided at an upper portion of the washing machine main body.

[0002]

2. Description of the Related Art A driving operation portion of a washing machine of this type includes a substantially horizontal upper surface plate serving as a driving operation surface, an electric equipment board (printed board), and the electric equipment board. It consists of a dish-shaped board cover that is horizontally received and attached below the top plate, and occurs inside and outside the washing tub during water supply, washing, and rinsing (both storing and pouring) during the washing operation process. There is a risk that splashing water and splashing water may enter the gap between the substantially horizontal top plate and the peripheral wall of the substrate cover, which is plate-shaped and attached to the back side of the top plate, and may adversely affect the electrical equipment substrate.

[0003]

According to the present invention, there is provided a washing machine having a washing tub provided in the main body of the washing machine, and a driving operation section provided at an upper portion of the washing machine body. But,
It is composed of a top plate including a driving operation surface, an electrical equipment substrate, and a dish-shaped substrate cover mounted below the upper surface plate for horizontally receiving the electrical equipment substrate and disposing it under the upper surface plate. There is provided a washing machine in which a peripheral wall of the substrate cover has a substantially U-shaped cross section, and the upper plate includes a downward rib extending downward along an outermost peripheral surface of the peripheral wall of the substrate cover.

That is, according to the present invention, the cross section of the peripheral wall of the substrate cover is substantially U-shaped, and the top plate is provided with downward ribs along the outermost peripheral surface of the peripheral wall of the substrate cover. Invasion of water and splash water can be prevented. Particularly, according to the configuration of the present invention, a narrow and long gap that can be formed between the peripheral wall of the substrate cover and the downward rib of the top plate, and two narrow gaps that can be formed by the substantially U-shaped portion of the peripheral wall and the back surface of the top plate. Water can be prevented from entering twice by the gap.
In the present invention, the cross section of the peripheral wall of the substrate cover is approximately U.
The letter shape means a standing piece that goes upward in a cross section from the peripheral edge of the bottom wall of the substrate cover, and an outer portion that bends to the outside of the standing piece from the middle of the standing piece or from the peripheral edge and goes upward. The cross-sectional shape means a bent piece or an upright piece and an inward bent piece that is bent from the middle of the upright piece to the inside of the upright piece and goes upward. Here, the upward piece of the upright piece and the outer bent piece having the inner bent piece should not be inclined outward. This is because if the outer cover is tilted to the outside, downward ribs of the upper surface plate, which will be described later, are formed along the outer peripheral surface, so that the substrate cover cannot be attached below the upper surface plate. The interval between the upright piece and the outer bent piece that go upward, that is, approach the surface of the top plate is not particularly limited, but is preferably 5 to 15 mm, and more preferably 8 to 12 mm. The approach distance between each piece (free end) and the top plate is preferably 1 mm or less. After all, the substantially U-shaped cross section of the peripheral wall of the substrate cover includes not only the accurate U-shaped but also the substantially V-shaped and the substantially Y-shaped. Meanwhile, downward ribs are formed on the upper surface plate along the outer peripheral surface of the peripheral wall of the substrate cover. The distance between the outer peripheral surface of the peripheral wall and the downward rib is
It is preferable that the amount is small in order to prevent entry of splashing water and splashing water, but it is usually set to 1 to 3 mm in consideration of workability when attaching the substrate cover below the upper plate. The length of the downward rib is preferably 10 mm or more, more preferably 15 mm or more. By the way, the configuration of the driving operation unit according to the present invention is not limited as long as it is a washing machine having a driving operation unit on the upper part of the main body and the washing tub is in an open state in the main body, and can be suitably applied to various washing machines. . Specifically, the present invention can be preferably applied to a one-tub type or two-tub type washing machine in which the rotation axis of the washing tub is vertical. The dish-shaped substrate cover can be formed into (a dish of) an appropriate shape corresponding to the shape of the operation surface, and specifically, can be formed into a substantially triangular shape or a substantially quadrangular shape.

If another downward rib is formed on the top plate so as to enter the substantially U-shaped section of the peripheral wall of the substrate cover, the splashing water and splashing water inside and outside the washing tub can be tripled to reach the electrical equipment substrate. Can be prevented. The length of the other downward rib that enters the substantially U-shaped section is preferably 5 to 10 mm. Further, a lead wire for electrical equipment is attached to a substantially U-shaped section of the peripheral wall of the substrate cover, and a hook for pressing the lead wire is formed, and the lead wire is pressed by the other downward rib through the hook. If so, it is possible to easily prevent the lead wire from protruding.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below based on the embodiments shown in the drawings. The present invention is not limited to this. First, referring to FIGS. 1 to 3, a fully automatic washing machine 1
Is mainly composed of a washing machine main body 2, a washing tub 3 provided in the main body, and a driving operation unit 4 provided on the upper portion of the main body 2.

The washing tub 3 is composed of an outer tub 5 which is elastically suspended and supported in the main body, and a dehydrating and washing tub 6 which is rotatably supported in the outer tub. The operation operating section 4 is connected to the electric operating printed circuit board 7, a plate-shaped substrate cover 8 for horizontally receiving the printed circuit board 7, and a substantially horizontal continuous operation operation surface.
It is composed of a top plate 9 that covers the substrate cover 8 from above.

The substrate cover 8 has a peripheral wall having a substantially U-shaped cross-section, and the electrical equipment lead wires 12, 13 ... Are attached to the substantially U-shaped cross-section and bent downward from the horizontal. The hook 14 is projected. The top plate 9 is the substrate cover 8
Downward rib 10 extending downward along the outermost peripheral surface of the peripheral wall of
And another downward-facing rib 11 that is inserted into the above-mentioned substantially U-shaped section. In addition, 15 and 16 are an inner wall and an outer wall of a substantially U-shaped section, 17 is an insulating material, 18 is a switch,
Reference numeral 19 is a pilot lamp, 20 is a boss projecting downward from the top plate 9, and 21 is a mounting screw for the substrate cover 8.

Thus, a narrow and long gap is formed between the peripheral wall of the substrate cover 8 and the downward rib 10 of the upper surface plate 9, and a substantially U-shaped section of the peripheral wall and the back surface of the upper surface plate 2 are formed. In addition to the two narrow gaps, another downward rib 11 is inserted into the U-shaped section (double structure) of the peripheral wall.
It is possible to triple prevent the intrusion of splashing water and splashing water generated inside and outside the washing tub 3.

Further, lead wires 12, 13 ... For electrical equipment are additionally provided on the substantially U-shaped section of the peripheral wall of the substrate cover 8, and these lead wires are connected to another downward rib 11 via a hook 14. Since it is held down, it is possible to prevent the lead wires 12, 13 ... The board cover 8 can be more easily fixed to the upper plate 9 by attaching the mounting screws 21 to the boss 20 of the upper plate 9 from below. That is, when mounting the printed circuit board on the control plate section as in the past and mounting it from above the top plate, the printed circuit board must first be screwed onto the control plate section, and then fitted into the top plate. It is necessary to tighten the screws from the top plate side and attach a cushion or cap that covers the screws. Therefore, in the prior art, a large number of screws are required and the number of assembling steps is large, which leads to an increase in cost, whereas in the present embodiment, it is possible to easily assemble with a small number of screws.

[0011]

According to the present invention, a narrow and long gap can be formed between the peripheral wall of the substrate cover and the downward rib of the top plate, or a substantially U-shaped portion of the peripheral wall and the back surface of the top plate. Two narrow gaps can prevent double splashes inside and outside the washing tub and splash water. Then, if another downward rib is formed on the upper surface plate so as to enter the substantially U-shaped section of the peripheral wall of the substrate cover, it is possible to triple prevent water from reaching the electrical equipment substrate.

Further, a lead wire for electrical equipment is attached to a substantially U-shaped section of the peripheral wall of the substrate cover, and a hook for pressing the lead wire is formed, and another downward rib is used to connect the lead wire through the hook. If pressed, the lead wire can be easily prevented from protruding.
