Description

Structure of drain valve for washing machine

The present invention relates to a structure of a drainage valve for a washing machine. In particular, a drainage plate in which a drainage hole is formed is installed in a drainage valve, and a bellows pipe operated by a drainage motor is installed in both spaces partitioned by the drainage plate. It relates to a structure of the drain valve for the washing machine to prevent the washing water leakage after the drain stroke.

In general, the washing machine is installed in the inside of the outer box 10, which is a rectangular cylinder, as shown in Figure 1 is suspended in the water tank 11 of the cylindrical body for receiving the washing water by the hook rods, the inside of the water tank 11 A plurality of water holes are formed and a washing tub 12, which is a cylindrical body in which laundry and washing water is accommodated, is installed while forming concentric circles, and a pulsator 14 for generating water flow is installed in the lower portion of the washing tub 12.

The pulsator 14 and the washing tank 12 have dual drive shafts and are axially coupled to the reduction gear assembly 16 mounted on the bottom surface of the water storage tank 11 to perform the washing and rinsing operations. Only 14) forward and reverse, and during the dehydration stroke, the pulsator 14 and the washing tank 12 are integrally rotated in any one direction, and the reduction gear assembly 16 has a driving motor ( 15) and the V-belt is connected. The upper plate 17 is provided with a control unit, an electric chamber and a door at the upper portion of the outer box 10, a balance 13 is installed at an upper end of the washing tank 12, and an upper end of the water storage tank 11. Shower ring 18 was installed.

In addition, a drain valve 20 and a drain motor 28 are installed at a bottom of the reservoir 11, and the drain valve 20 is pulled by the wire 26 by the operation of the drain motor 28 during the stroke of the drain. The bellows pipe installed in the ground is contracted to drain the washing water through the drain pipe 22 connected to the reservoir 11 and the drain pipe 24 coupled to the outer box 10.

The conventional drain valve 20 is composed of drain pipes 22 and 24 installed in different directions as shown in FIG. 2 and a cap 21 covering one side of the cylinder with a cylinder having a predetermined size of space. The inner space 25 is connected to the inner space through the cap 21 and an inner body 25 having a coil spring is installed, and an elastic spring 27 and a bellows pipe are disposed around the inner body 25. 23 was installed.

And the drain valve 20 is the coil spring is pulled by the wire 26 and at the same time the inner body 25 is interlocked, the bellows pipe 23 is contracted, so that the drain pipe (22, 24) to communicate with each other It was to drain the laundry water in the reservoir to the outside. However, the drainage valve 20 configured and operated as described above is gradually reduced in the restoring force of the bellows pipe 23 so that washing water located in the drain pipe 22 flows through one side of the bellows pipe 23 and leaks. There was a problem.

The present invention has been made in consideration of the above circumstances, and an object thereof is to provide a bellows pipe which is operated by a drainage motor in each of the two spaces partitioned by the drainage plate while installing a drainage plate having a drainage hole formed in the drainage valve. It is to provide a structure of the drain valve for the washing machine installed to prevent the washing water leakage after the drain stroke.

The present invention is to control the discharge of the washing water in the reservoir to the outside during the drainage stroke in order to achieve the above object, the drain pipe is formed on one side and the bottom of the horizontal height cylinder, respectively, on the other side A cap screwed with a pair of holes formed therein, and a housing in which an engaging jaw is formed on an inner wall of the cap and an inner surface of the cap opposite thereto; A drain plate installed on the engaging jaw of the housing to partition the inner space of the housing up and down in a horizontal direction and having a plurality of vertically penetrating holes; It is provided in each of the space portion, is connected to each of the wire of the drain motor is operated, and provides a structure of the drain valve for the washing machine including the first and second bellows pipe opening and closing the drain pipe by pulling and releasing the wire Is in.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

3 shows a structure of a drain valve for a washing machine according to the present invention. The structure of the drain valve for a washing machine includes a housing 320 in which drain pipes 220 and 240 are directly formed, and an inner space of the housing 320 is horizontal. To operate the first and second bellows pipes 230 and 231 and the first and second bellows pipes 230 and 231 installed in the upper and lower spaces to control the drain pipes 220 and 240. It consists of a wire 260 to.

The housing 320 is a circular cylinder installed in a horizontal state is formed with a drain pipe 220 connected to the reservoir tank on one side wall, a drain pipe 240 for discharging the washing water to the outside is formed on the bottom surface, the drain pipe The cap 210 is screwed to the other side surface 220 is formed is coupled. A pair of horizontally penetrating holes are formed in the cap 210 while maintaining a constant gap, and the locking jaws 201 and 202 having corresponding heights on the inner wall of the housing 320 and the inner wall of the cap 210, respectively. ) Is formed, the catching jaw 201 is formed in a position close to the drain pipe 220, the catching jaw 202 maintains the same height as the catching jaw 201 and of the cap 210 It is formed on the inner surface.

The drainage plate 300 is a plate having a plurality of drainage holes 310 vertically penetrated so as to be mounted on the top of the locking projections 201 and 202 in the housing 320.

The first and second bellows pipes 230 and 231 are respectively provided with first and second inner bodies 250 and 251 having coil springs embedded therein, and elastic springs 270 and 271 are respectively installed on the outer surfaces thereof. Springs are provided with respective first and second wires 261 and 262 so that the ends are connected to each other.

One end of the wire 260 is connected to a drainage motor (not shown), and the other end of the wire 260 is connected to the connection parts of the first and second wires 261 and 262 with a plate-shaped pull plate 263 interposed therebetween. do.

When the drainage motor is operated and pulls the wire 260 during the drain stroke, the present invention configured as described above, the first and second wires 261 and 262 are simultaneously pulled by the pulling plate 263 which is addressed thereto, and then the first and second The second bellows pipes 230 and 231 are pulled out and contracted, and then the washing water drained through the drain pipe 220 is discharged to the drain pipe 240 through the drain hole 310 of the drain plate 300.

When the operation of the drainage motor is stopped, the wire 260, the pulling plate 263, and the first and second wires 261 and 262 are applied to the restoring force of the elastic springs 270 and 271 installed in the first and second bellows pipes 230 and 231. In addition, the first and second bellows pipes 230 and 231 are restored to their original positions to block the drain pipes 220 and 240.

Therefore, the drain pipe 220 is the first bellows pipe 230, the drain pipe 240 is intermittently controlled by the second bellows pipe 240 at the same time, and the wash water is leaked by the drain plate 300 inherently Will be prevented.

According to the present invention as described above, by installing the first and second bellows pipe (230,231) in the housing 320, and by installing the drain plate 300 having a drain hole 310, the original wash water leakage There is an effect that can be prevented.
