Description

[Detailed description of the invention] The present invention relates to a washing machine.

FIG. 1 shows a conventional washing machine, in which the operating section is located on the rear side of the main body. That is, in the figure, (1) is the main body of the washing machine, (2) is the T plate attached with screws to the L end of this main body (1), and the operation box is located on the rear side of this L plate (2). (3) It is formed in one piece. (4) is an operation panel to which an operation switch (5) is attached, and this operation panel (4) can be replaced by one operation box (3).

(6) is a washing tub provided in the main body (13), and a pulsator (8) rotated by a motor (7) is provided at the lower end of the washing tub.
) is provided. (9) is the plate (a lid that opens and closes the opening (2a) of 2J. By the way, in this conventional washing machine I, the washing process is carried out by the controller Ql attached to the operation plate (4)). The operation is performed using the operation switch (5). Figure 2 shows the details of the mounting part of the controller αQ, and the boss (
b) are integrally molded. For this reason, sink marks occur on the surface of the operation plate (4) of the boss 01) forming portion during molding. In order to hide this beard, it is necessary to cover the surface of the operation panel (4) with a makeup mask. In addition, the operation plate (4) has a protruding leg plate portion (4) at its lower end.
a) The protruding leg temporary holder of the operation box (3) is engaged with the part (8a), and the end is screwed into the operation box (3) by the screw (2).
is fixed to. Further, FIG. 8 shows an enlarged view of the main part of another conventional example. In the conventional example shown in Fig. 8, only the controller 〇〇 is located on the rear side of the main body (υ), and the operation switch is not provided on the rear side of the main body (1). In order to attach the mounting plate (b) for installing controller a1 from the back side of the rear side, 1?: Standing plate (2+
A boss Q8 is provided on the inner surface of the rear end and extends downward one inch. In addition, QQ is a mounting plate (standing plate to support the front end of 141).
This is a boss formed on the stepped portion of 2-. As mentioned above, when the boss (A) is formed on the inner surface of the rear end of the vertical plate (2), a whisker will be generated at the t end of the boss (4), and the surface of the vertical plate (2-) will be deformed. The surface of the standing board (2) is covered with a decorative board Qη to hide it.
Since the controller requires holes for attaching the controller Q01, water may enter through the holes in the flea in the direction of arrow P and splash onto the controller Q01. Therefore, the holes are sealed with a waterproof sealant such as Botmelt. In addition, the strength of the boss (a) is weak, and if reinforcing ribs or the like are added, there is a risk that that part will shrink.

In addition, the addition of reinforcing ribs increases the material cost, and furthermore, the screw holes provided inside the boss suffer from sinking, which affects the tightening screws.

The present invention has been made to eliminate the drawbacks of each of the conventional examples listed in L.
This will be explained based on FIGS. 4 to 7). Figure I
υ is a standing plate attached to the main body of the washing machine 1 by screws on the L end of the If-rock. There is. H is the controller that controls the operation switch @, and this controller (C) is attached to the mounting plate (A) attached from the rear side of the standing board (goods). To describe the mounting structure of this mounting plate (c) in detail, the plate (b) is formed with a recess (a) for storing the lid (a),
A boss (2) for fixing the front end of the mounting plate (2) is provided at the bottom of this recess (A), and a T plate (2) for fixing the rear end of the mounting plate (2) is provided. A boss 4 extending downward is provided at the rear end of υ. This boss (2) is provided on the inner peripheral surface of the rear end of the T plate eυ, and the boss (2) extends upward along the inner peripheral surface of the rear end of the T plate eυ and is continuous with the thin rib (to) from the middle. This thin rib crest is connected to the inner surface of the t-end of the standing plate (b). In this way, the vertical plate having thin ribs (1) is integrally molded from synthetic resin. By the way, the thickness A of the thin rib (7) is tf2G! υ
The thickness of the t-end of the t-end is less than or equal to i of B. In addition, in order to form the thin ribs, a mold that slides back and forth is used along with undercutting. The mounting plate (2) is long in the horizontal direction, and a plurality of bosses (supports) 4 are provided at appropriate intervals, and tighten the mounting plate 4 against each boss L24@ with screws 0) stem 1. Therefore, it is tightened from below. Furthermore, the thin rib (to) is formed along the outer periphery of the boss 4, as can be seen from FIG.

The washing machine of the present invention can be implemented as described below, and the relationship between the thin ribs and the bottom surfaces of the four parts of the standing plate can reliably prevent sinking of the boss part, and the surface of the plate can be directly seen. 1. Improved appearance by eliminating deformation caused by sink marks during molding.
You can cross it.

In the conventional example, the sink mark caused by the boss was hidden by a decorative board, so a decorative board was required, which increased the number of man-hours for installing the decorative board and increased the cost.However, according to the present invention, the decorative board It is possible to reduce costs without the need for In addition, in the conventional example, it is necessary to make holes in the upright board and the operation board for attaching the decorative board, so water can enter through the holes.
Failure to do so may result in poor insulation of electrical components and the risk of electric shock.
In order to prevent this, preventive measures have been taken by blocking the holes with hot melt, etc., which results in an increase in the number of unnecessary parts and a low performance. I will list something that can solve these shortcomings all at once. In some embodiments of the present invention, the thickness of the thin ribs (to prevent sinking) is set to one or less of the thickness of the leg end of the standing board, but depending on the molding material, it may be more than 100 F. This is possible by simply changing the mold, and you can make changes while checking the mold. In addition, the thin ribs formed along the outer periphery of the bosses 4 also act as pillars to prevent the rear surface of the upright plate from deflecting. As described below, since the boss for attaching the mounting plate can be formed integrally with no sink marks and with great strength, it is possible to securely attach the mounting plate to the plate, and also to attach the mounting plate to the plate. Even if a heavy controller or the like is attached to the structure, it will not come off due to impact, and a strong structure can be obtained.
