Description

[Detailed description of the invention] Conventionally, drain valve devices for washing machines, etc., open and close the valve by operating a bar-shaped rod from its extending direction, but since the operation is restricted in the extending direction of the rod. The operation of the button was limited, and there were problems with installing it in a narrow space.

The present invention solves this problem by using a bendable rod.

An embodiment of the present invention will be described below based on the accompanying drawings.

In the figure, 1 is the outer frame of the washing machine. Inside the outer frame 1, there is a washing tub 2 and a dehydration receiver 3. Inside the dehydration receiver 3, a freely rotatable dehydration tank 4 is arranged. In addition, the dehydration tank 4 is connected to the shaft of a dehydration motor 5 supported in a vibration-proof manner on the outer frame 1V.

Reference numeral 6 denotes a suspension that supports the dewatering motor 5 in an outer frame IVC buffer manner, 7 indicates a stirring blade disposed on the bottom surface of the washing tub 2, and 8 indicates a suspension provided on the bottom surface of the washing tub 2 in close proximity to the stirring blade 7. A drainage filter 9 having a drainage hole 9' is mounted in the recessed part 8.

Reference numeral 10 denotes a drain port integrally formed on the bottom surface of the recess 8, and a valve housing 1 constituting a drain valve device is provided on the inner surface of the drain port 10.
1 inlet 12 is installed.

Reference numeral 13 indicates a claw portion formed at the tip of the inlet port 12 of the valve housing 11 to protrude inwardly, and reference numeral 14 indicates a bottom recess 8 of the washing tub 2.
A holder for the valve casing 11 is fixed to the holder, and the holder 14 has a claw part 15 formed at the lower end that engages the claw part 13 of the inlet port 12, and a claw part 16 formed at the upper end engages the claw part 13 of the inlet port 12. A claw portion 17 formed on the filter 9 is engaged.

18 is a valve body provided in the valve housing 11, and this valve body 1
8 is connected to a flexible portion 20 that includes a valve body ridge portion 19 having a spherical shape upward and a flexible portion 20 that bends when the ridge portion 19 is moved up and down to open and close the valve. , and a vertical seal portion 2 that prevents water leakage between the lower part of the valve body 18 and the valve housing 11.
1, and a spherical seal portion 22 extending horizontally from the lower end of the vertical seal portion 21.

The ridge portion 19 of the valve body 18 is in watertight contact with the valve seat 23 of the valve housing 11, and the outer periphery of the vertical seal portion 21 is in close contact with the lower inner wall of the valve housing 11, and the inner periphery is in close contact with the lower inner wall of the valve housing 11. It is in close contact with the outer wall of the circular protrusion 25 of 24 and acts as a seal between the two.

The spherical seal portion 22 having a diameter of
6 and the flat portion 2γ of the valve housing lid 24 to prevent water leakage.

The valve housing lid 24 is fixed to the valve housing 11 by using claws 28 provided at several locations on the peripheral edge 26 of the valve housing 11 to protrude downward, and holes provided at several locations on the outer peripheral edge 29 of the valve housing lid 24. Insert 30,
The claw portion 28 and the lower end portion 29' of the outer peripheral edge portion 29 are engaged.

The claw portion 28 and the hole 30 are connected to the valve housing 11 as shown in FIG. The buttons are formed at equal intervals in the circumferential direction of the valve housing lid 24, and by rotating the valve housing lid 24, the mounting position of the buttons in the circumferential direction can be changed.

Reference numeral 31 denotes a cavity formed around the center of the valve housing lid 24, which prevents the flexible portion 20 of the valve body 18 from hanging down when the valve is opened, and facilitates vertical movement of the valve body 18.

Reference numeral 32 denotes a cylindrical projection formed in the center of the valve housing lid 24. A compression spring 33 is installed on the inner peripheral surface of the projection 32, and this compression spring 33 is attached to the ridge 19 of the valve body 18. The inner wall of the valve housing 11 is pressed upward so that the ridge 19 comes into close contact with the valve seat 23 of the valve housing 11, thereby blocking the flow channel.

The cylindrical projection 32 also serves as a guide to prevent the compression spring 33 from fully bending.

Reference numeral 34 denotes a connecting fitting having one end molded on the ridge of the valve body 18 and the other end protruding downward.
It is connected to a bendable rod 36 such as a metal plate.

Further, this rod 36 is operated by an operation knob 38 on an operation panel 37 of the washing machine.
By rotating the rod 36, the rod 36 is pulled, and the direction changing guide section 39 formed in the valve housing cover 24 changes the direction of the rod 36 from the horizontal direction to the vertical direction. The ridge 19 of the body 18 is compressed by the spring 3
Pull down against the urging force of step 3 to open the valve.

The direction conversion guide 39 has a curved surface that is curved downward from the center of the valve casing lid 24, and there are provided on both sides thereof to prevent the rod 36 from coming off the guide portion 39. In order to reinforce the guide part 39, the guide wall 40
are integrally formed.

Further, the rod 36 slides on the outer peripheral lower wall of the drain pipe 41 so as to be transmitted to the guide portion 39 of the valve housing cover 24.

A means (not shown) is provided on the outer peripheral lower wall of the sprouted drain pipe 41 for positioning the rod 36 in sliding contact so that it does not come off a predetermined sliding contact area.

Reference numeral 42 denotes a drain port for the dehydrated liquid provided on the bottom surface of the dewatering receiver 3, and one end of a drain pipe 43 is connected to the drain port 42.
The other end of the drain pipe 43 is connected to the outlet 44 of the valve housing 11.

Reference numeral 45 denotes an overflow port provided on the upper side wall of the washing tub 2. One end of the overflow pipe 46 is connected to the overflow port 45, and the other end of the overflow pipe 46 is connected to one end of the drain pipe 41. has been done.

The other end of the drain pipe 41 communicates with an external drain hose 4γ.

The washing liquid in the washing tub 2 to be poured after washing is transferred to the valve case 11.
The water then passes through the outlet 44 and is discharged to the outside through the drain pipe 43° and the external drain hose 41.

The dehydrated liquid passes through a drain port 42 and a drain pipe 43, joins with the washing liquid, and is similarly discharged to the outside through an external drain hose 47.

In view of the above-mentioned configuration, the present invention particularly provides a valve housing having an inlet and an outlet, a valve body provided in the valve housing to open and close the inlet, and a bendable valve body for opening and closing the valve body. a rod, and a valve housing lid capable of switching a mounting device in the circumferential direction to the valve housing so as to hold the peripheral edge of the valve body between the valve housing and the valve housing lid. A curved guide button on which the rod passing through the guide button slides and changes its tension direction, and guide walls located on both sides of the guide part are integrally formed in the central part of the valve housing cover, The rod can be operated from a relatively free direction without restricting the direction in which it is pulled.

Specifically, the valve housing lid has a circumferential VC in the valve housing and its mounting position can be changed, so that it can be pressed in a narrow space, etc.
The direction of the curved guide can be set to the most suitable state for tensioning the rod, allowing for rational design when forming a drainage passage. Since the guide wall is provided in the center of the valve housing lid, the rod can always be safely delivered and its direction can be changed, and a stable degree of bending of the rod can be obtained, and the operating force of the rod can be stabilized.

Moreover, since the guide button and guide wall are integrally formed with the valve housing lid, there is no need for parts to attach the guide button and guide wall to the desired locations, reducing the number of parts and making assembly easier. It's easy.
