Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a washing machine that is equipped with an injection channel to the lower part of the washing tub and a cover that closes the injection channel, and a lint filter device is attached to the cover.

(B) Prior Art A washing machine capable of lower water injection has a vertically elongated water injection channel 2 formed at a corner of a washing tub 1, as shown in FIG. The injection channel 2 is closed by a plate-shaped cover 3, which is fixed to the tank wall by means of claws 4, etc., with both ends of the cover 3 placed against both ends of the opening. As shown in FIGS. 1 and 2, this cover 3 has two horizontal rows of lower water inlet groups 5 protruding from the bottom, a bulge at the top, and a mounting recess here. 6, and a communication hole 7 communicating with the injection channel 2 is bored in the recess 6. The outer periphery of the recess 6 is flat, and a protective rib 8 is further provided upright on the entire outer periphery. In the recess 6 inside the protective rib 8 and its outer periphery, a lint filter device F is provided, in which a bag-shaped net member 9 is fixed to a mounting frame 10.
They are removably fitted using the mounting frame 10 and fixed with nails or the like. The protective rib 8 is flush with or higher than the mounting frame 10 of the fitted device F, and protects the mounting frame 10 from collisions with water flow or clothing and prevents the device F from falling off. .

Reference numerals 11 and 11 designate a group of introduction holes that are vertically bored on both sides of the recess 6 in the bulge, and guide the reversing water flow into the injection channel 2. Reference numeral 12 denotes a rectifying means formed opposite to the recess 6 in order to divert the water flow introduced from the introduction hole group 11, 11 to the lint filter device F, and is integrally formed inside the cover 3. As shown in FIG. 3, a flow regulator 13 having a substantially V-shaped cross section is erected so that its tip is located inside the communication hole 7, and the net member 9 is prevented from being recessed inward of the communication hole 7. A tongue piece 14... is provided on. The rectifying means 12 directs the water entering from the left and right introduction hole groups 11, 11 independently toward the communication hole 7 each time the water flow is reversed.

Reference numeral 15 denotes a resistance wall provided vertically and over a predetermined length on the cover 3 above the bulge, which protrudes in a mountain shape toward the center of the tank and reduces the strength of the water flow at the corner of the tank. This helps the introduction to equipment F.

Here, since the cover 3 is a resin plate having a vertically long shape and a predetermined width, it is easily bent.
In order to reinforce this, as shown in FIG. 4, a straight reinforcing rib 16 is integrally formed in the inner surface of the cover at the boundary between the bulging portion and the resistance wall 15 with a predetermined projecting length in the horizontal direction. In addition, reinforcing ribs 17 are also provided in the vertical direction.
17 are integrally formed.

As a result, the reinforcing ribs 16 have a fan-shaped planar shape and are perpendicular to the injection channel 2, so that when water is supplied from the top, the supplied water can be directed in both directions as shown by the arrows in FIG. disperse. Therefore, this dispersed water overflows from the introduction hole groups 11, 11 on both sides or leaks from the seams at both ends of the cover 3, giving the user the impression that the product is defective at the initial stage of water supply. give.

(c) Purpose of the invention The purpose of the invention is to maintain the reinforcing function while suppressing water leakage during water supply so that water can be supplied with good appearance.

(d) Structure of the invention In the present invention, horizontal reinforcing ribs are formed in a so-called V-shape, and the supplied water hitting the reinforcing ribs is collected in the center and is allowed to fall from there to the lower part. That is, water is prevented from dispersing in both directions, and is allowed to flow directly down to the lower part of the water injection channel to reach the lower water injection port group, thereby suppressing water leakage and the like.

(E) Embodiment This will be explained based on FIGS. 6 and 7, and the same numbers as those in the conventional example are given the same numbers. Here, the reinforcing rib 16' is formed in a V-shape or a U-shape. That is, the central part is concave downward,
The supplied water received here is collected in the center and flows down. Therefore, since dispersion in both directions is eliminated, water overflowing from the introduction hole groups 11, 11 and water leaking from the joints on both sides of the cover is reduced, and the appearance when water is supplied is improved. In addition, this reinforcing rib 1
6' is the same as the conventional example in that it stands integrally on both sides from the inner surface of the cover 3, so it has a reinforcing function against the bending of the cover 3.

Furthermore, when water is sufficiently supplied into the washing tub 1 and then lint is removed while rinsing with water, the supplied water is collected in the center by the reinforcing ribs 16' and then passes through the flow regulator 13 as it flows down. be able to. That is, it is separated from the water flow introduced each time the inversion occurs. Therefore, since the introduced water flow is less disturbed, the work of collecting lint in the water flow is not disturbed, and the collection efficiency is improved.

(f) Effects of the invention The present invention provides a washing machine with a good appearance when water is poured into the lower part and has high commercial value.
