The present invention relates to an apparatus for discharging an electric washing machine, and more particularly, to an apparatus for discharging an electric washing machine which can variably control the water level while preventing leakage of washing water during a washing operation and a rinsing operation.

In general, a representative example of a conventional electric washing machine is configured as shown in FIG. In Fig. 1, reference numeral 12 denotes an outer tub of a washing machine, in which a washing tub 7 and a dewatering tub 11 are incorporated. The drainage hole is formed on the side wall of the washing tank 7 so that the water in the washing tank 7 is automatically adjusted by setting the low, medium, and high water levels by the water level control switch 2 provided in the control box 5. The formed rotor (7) is attached, the lower portion of the rotary blade (8) which is rotated in accordance with the setting program of the washing control timer (1) via a writer by the rotational driving force of the washing motor (9) It is arranged. After the washing is finished, put the laundry in the washing tank (7) in the dehydration container (11) and set the dehydration control timer (4) at a predetermined time while the dehydration motor (13) is rotated by the set time while the dehydration container (11) As it rotates, the washing water contained in the laundry is dewatered, and the washing water is drained out of the outer tub 12 of the washing machine through the discharge pipe 10. On the other hand, the washing water in the washing tank (7) is also discharged through the discharge pipe (10) when the drainage adjusting knob (3) is set in the drainage program, and the washing water of the water level higher than the water level set by the water level control switch (2) is also fluttered. Of course, it is discharged out of the outer tank 12 through the discharge pipe 10 through the hole formed in (6). In the figure, reference numeral 14 denotes a base disposed in four lower nose holders to support the washing machine.

However, in the drainage device of the electric washing machine configured as described above, as shown in FIGS. 2 to 3, the packing 21 is assembled at the lower end of the drainage fixture 18 and shown at the upper side of the hydraulic pressure sensing pipe 20. As described above, the water pipe 15 is coupled, and one end of the hydraulic hose 19 is connected to a hole of a small diameter integrally formed at the upper side of the hydraulic pressure sensing pipe 20, and then the other end is connected to the control box ( 5) is connected to the hole formed in the lower portion of the water level control switch (2), and then the lower end of the water pressure sensor tube 20 is connected to the discharge hole of the drainage fixture 18. Thereafter, the drainage support 17 having the fixing groove 26 at the lower end thereof is fixed to the fixing hook 28 of the drainage fixing stand 18 to couple the discharge device in an integrated state to the side wall groove in the washing tank 7, and to drain the A compression spring 16 is inserted between the spring support rib 17 formed on the upper surface of the support 17 and the spring fixing tube portion 39 formed under the control box 5, and integrated into the drain support 17. The water level indicator displayed on the control box 5 is fixed by fixing one end of the drain control wire 24 to the drain control wire hook 27 that is formed and connecting the other end to the drain control lever 28. For example, if the water level control switch (2) is set to low, medium, and high, and the washing water is supplied into the washing tank 7, the washing water in the washing tank 7 is discharged from the point Y of FIG. 3, that is, from the lower end of the pressure sensing tube 20. When water is supplied, washing is supplied to the washing tank 7 from the point Y of FIG. The water pressure of the water is sensed by the water pressure sensor tube 20 and is transmitted to the water level control switch 2 through the water pressure hose 19 to adjust the water supply amount.

If the user sets the water level control 2 to 'high' among low, medium and high, the water pressure supplied to the water pressure sensing pipe 20 is transmitted to the water level control switch 2 through the water pressure hose 19. At this time, when the washing water is supplied to the height of the 'high' in the washing tank (7), the power supply (not shown) stops the water level control switch (2) and performs the washing stroke. At this time, any one of the high, medium, and low water levels is selected, and power (not shown) is applied to the washing control timer 1 by the water pressure, so that the washing operation is performed by operating the washing control timer 1. It is.

After the washing is finished, the drain control knob 3 is switched to discharge the wash water, and the drain control wire 24 having one end connected to the drain control wire hook 27 of the drain support 17 is the drain control knob 3. In conjunction with the operation of the drainage control lever 28 installed on the lower side of the pulled to the upper, at this time, the packing 21 was blocking the drain hole 32 is lifted to the upper can discharge the wash water through the discharge pipe 25. It is supposed to be.

Moreover, in order to improve such a conventional fault, there exists also the drainage of an electric washing machine as shown in FIG. The discharge device of the electric washing machine having such a structure has a drainage support 17, a drainage fixture 18, a water supply pipe 15, and a hydraulic pressure sensing pipe 20 integrally formed, and also a small inner diameter. Since the water flow pipe 15 having a long length L is formed by injection molding, deformation occurs as the use time elapses, and the protruding plate 36 is integrally formed to form the hydraulic pressure sensing pipe 20. In addition, the discharge device installed in the washing tank 7 is separated from the washing tank by the flow of the discharge device to the left and right or front and rear by the vertical flow relationship in which the discharge device installed in the washing tank 7 pulls the drainage control wire 24 upward. In some cases, the operation may not be performed smoothly, and the packing 21 which is blocking the drain hole 32 may not be tightly coupled, and water may be leaked. Also, the laundry may not be rinsed at the medium and low water levels.

After bonding the upper discharge pipe (60) and the lower discharge pipe (70) by adhering to the outer circumferential surface of the connecting pipe portion formed inside the fixing member (71) of the 70, the rinsing hose (80) in which the elastic means (81) are decompressed on the outer circumference. One end of the drain control wire 24 'is connected to the hose wire hook 80a of the c) and the hose wire hook 80a is inserted into the drain hole 60a of the upper discharge pipe 60 with the upper portion thereof. Fix the rinsing hose fixing part (80c) to the outer circumference of the rinsing hose fixing tube (70d) with an adhesive or a screw. , The drains of the electric washing machine according to the present invention by combining a packing 21 to the upper and lower projecting plate 59 (59 ') is completed.

Thus, as shown in FIG. 7, the discharge device in which the fabrication is completed is inserted into the outer circumference of the spring fixing tube portion 41 integrally formed at the lower end portion of the control box 5, and then the upper portion from the lower portion thereof. Insert the upper portion of the discharge pipe 60, and connect one end of the drain control wire 24 to the drain control wire hook 64a integrally formed on the spring support plate 64 of the upper discharge pipe 60, and the other end It is connected to one end of the drain control lever 28 provided in the lower part of the drain control knob (3).

At this time, the other end of the drain control wire 24 'connected to the hose wire hook 80a of the rinsing hose 80 is connected to maintain a desired length, that is, a length that is linked to the operation of the water level control switch 2. At the same time, the packing 21 is placed in the drainage hole 32 formed in the lower part of the washing tank 7, and the packing 21 has a discharge pipe 10 and a drain hose connected to the outside of the washing tank 7. 22) closely connected with each other.

The discharge device of the present invention connected as described above has the outside of the spring fixing tube part 41 by the length of the upper discharge tube 60 along the spring fixing tube part 41 when the drainage adjusting knob 3 is switched to the drainage side after the washing is finished. Since the packing 21 is lifted up in the vertical direction in accordance with the drainage hole 32 of the lower discharge pipe 70 while being supported by the drainage hole 32, the drainage hole 32 is opened, and the washing water in the washing tank 7 is filtered through the filter 6. It is discharged out of the outer tub 12 through a plurality of holes formed in the). In addition, since the upper end of the upper discharge pipe 60 is supported by the outer side of the spring fixing pipe portion 41 by the length l, when the discharge operation, that is, when the drainage control wire 24 is pulled by the drainage control lever 28 In the discharge device is pulled without being separated toward the spring fixing tube portion (41). In other words, when the drainage control wire 24 is pulled upward, the discharge device does not move from side to side or front and rear in accordance with the vertical flow relationship, so that it is not separated from the washing tank 7 and the drain control lever 28 and Since the compression spring 16 generally flows only in the up and down direction, even when the drainage device is lowered, the packing 21 can close the drain hole 32 tightly so that no leakage occurs.

In addition, the drainage device of the electric washing machine according to the present invention not only easily discharges the washing water in the washing tank 7, but also suppresses the occurrence of leakage in the washing stroke and the rinsing stroke, and at the same time, the operation of the water level control switch 2 Since the laundry can be rinsed while the water is continuously rinsed by the interlocking drainage control wire 24 ′, the bubbles and debris generated in the washing tank 7 during the water supply and rinsing are rinsed through the rinse hose 80. The outer tank 12 can be discharged to clean laundry.

In other words, when the user sets the water level control switch 1 to 'high' among the low, medium, and high marks displayed on the control cover during the rinsing operation of the laundry, the contracting force of the elastic means 81 is generally used. The rinsing hose 80 located at the low water level is operated in conjunction with the operation of the water level control switch 2, and upwardly operated by the drain control wire 24 'having one end connected to the water level control switch 2 (not shown). By the high water flow to the lower end of the water flow hole (60b) is drawn up and lather through the high water level water hole (60b) formed in the upper discharge pipe (60) without overflowing even if the washing water continues to supply to the washing tank (7) The water flows into the rinsing hose 80 together with the washing water and is discharged out of the outer tank 12 through the drain hole 32, the discharge pipe 10, and the drain hose 22.

In addition, when rinsing the laundry while watering, the washing water containing bubbles or debris that has not been discharged through the rinse hose 80 is discharged through the residual hole 70b. When the water level control switch (2) is set to the 'medium' level, the rinsing hose 80 is pulled up to the lower end of the medium level water hole (60c), at this time washing water containing bubbles or debris during rinsing Of course, it is discharged out of the outer tank 12 through the rinsing hose 80 through the middle water flow hole (60c), and the operation is also omitted when setting the 'low' level.

As described above, according to the discharge device of the electric washing machine of the present invention, since the upper lower discharge pipe and the rinsing hose forming a tapered shape are simply configured, the number of parts is small, the assembly is easy, and the discharge device is deformed over time. Not only this, there is almost no flow from the washing tank to the left and right or front and rear sides at the time of drainage operation, so that there is no effect that the discharging device is released. In addition, since the discharge device is moved vertically and vertically, the packing tightly closes the drain hole, so that no leakage of washing water occurs during washing and rinsing, and the selected water level is selected during the washing or rinsing operation selected from low, medium and high. Since the rinse hose is built so that it can be set, the washing water containing foam or debris can be discharged out of the outer tank while supplying the washing water, so that it can be washed cleanly.
