Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a washing machine overflow device in which the overflow surface of a washing tub can be arbitrarily varied.

The structure of a conventional example and its problems The conventional structure will be explained with reference to FIGS. , 4 is an overflow chamber recessed in a part of the washing tub 2, and is separated from the washing tub 2 by an overflow filter 6 having a large number of water passage ports 6. A guide groove 7 is formed.A guide groove 8 is provided in the overflow chamber 4 so as to be movable up and down.
Funnel-shaped overflow body communicating with overflow channel (not shown), 9
1 shows a positioning body provided on the overflow eye body 8, which has a convex portion 11 that removably engages with an uneven portion 10 formed on the rear groove edge of the guide groove 7 in the overflow filter 6. 1
2 is an operator installed on the washing tub 2 side of the overflow filter 6;
3 is a lip connecting this operator 12 and the overflowing eye body 8, 14
is the overflow surface display section.

In the above configuration, when the overflow eye body 8 is moved up and down via the operator 12, the overflow surface of the washing tub 2 changes in response. Here, the vertical movement of the overflowing eye body 8 is performed by applying an external force greater than the engagement force between the uneven portion 1o and the convex portion 11 to the operator 12, and elastically deforming the positioning body 9.

However, with the above configuration, a large force is required to disengage the uneven portion 1o and the convex portion 11, which causes a problem in terms of operability. Furthermore, if the engagement force between the concave and convex portions 10 and the convex portions 11 is weakened in consideration of the above-mentioned operability, there is a drawback that the water level in the washing tub 2 may drop abnormally due to the overflow eye body 8 falling unexpectedly due to vibrations or the like. Ta.

OBJECTS OF THE INVENTION The present invention eliminates these conventional drawbacks, and aims to reliably maintain the set overflow level and improve operability.

Structure of the Invention The overflow device for a washing machine of the present invention includes an overflow chamber that communicates with the washing tub through an overflow filter, and an overflow chamber that is vertically movable and that is formed in the overflow filter. An overflow eye body having an operator facing the washing tub side through a guide groove, and a positioning body provided in connection with the operator, and the positioning body and a part of the overflow filter facing this are provided. A concavo-convex portion and one or more convex portions that engage with each other are formed in between, and the operator is further provided with an engagement disengaging operation for displacing the positioning body to disengage the concave-convex portion and the convex portion. The positioning body is elastically displaced via the disengagement operation part, so that the part of the overflowing eye body that has released the engagement between the uneven part and the convex part can smoothly move up and down. This is what I did.

Description of examples The embodiment will be described below based on FIG. 4.

Note that FIG. 4 shows only the main parts, and the other parts are the same as the conventional examples shown in FIGS. 2 and 3, so the explanation is omitted.

In the figure, numeral 21 is an operator that moves up and down the overflowing eye, and faces the washing tub side. 22 is a vertical guide groove formed in the overflow filter 23; 24 is the overflow filter 2;
3 is the positioning body arranged on the overflow chamber side, 26 is the guide groove 2
2 and connects the operator 21 and the positioning body 24.

The operator 219 positioning body 24 and rib 25 are integrally molded from synthetic resin.

Reference numeral 26 denotes an uneven portion formed in the vertical direction on the side groove edge of the overflow chamber of the guide groove 22, and 27 indicates a protruding portion that detachably engages with a part of the uneven portion 26, and is formed on the positioning body 24.

Reference numeral 28 denotes a lock release operation section connected to the operation element 21 in a U-shape, and a suppressor 29 protrudes from the tip thereof, passing through the guide groove 22 and diagonally facing the free end of the positioning body 24. It is.

In the above configuration, if you want to change the overflowing surface of the washing tub,
First, the uncoupling operation section 28 is operated clockwise to press the positioning body 24 with the suppressor 29 thereof. Then, the positioning body 24 is displaced to the right in the figure and the convex portion 27
is separated from the uneven portion 26, and therefore, the operator 2 is free from the overflow filter 23.

From the above, the watery eye body can be moved up and down smoothly via the operator 21. When the overflowing eye body reaches the set position, except for the operation force of the disengagement operation part 28, the convex part 27 engages with a part of the corresponding uneven part 26 by the elastic return of the positioning body 24. be.

Note that the formation positions of the uneven portions and the convex portions may have a relationship opposite to that of the above embodiment, and the number of convex portions is not limited to one, but may be plural.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, according to the present invention, the overflow surface of the washing tub can be easily and smoothly controlled, and the set overflow surface does not fluctuate unexpectedly, resulting in excellent effects.
