Description

[Detailed description of the invention] The present invention relates to a water supply device for a washing machine, in which a water supply pump is rotatably fitted into a water supply tube to which a water supply hose is connected, and the direction of the water supply pump is changed by rotating the water supply pump. This allows water to be supplied to different locations, allows the water supply pipe to rotate smoothly, and prevents electrical components from getting wet even if the amount of water supplied is large and water overflows from the fitting part of the water supply pipe and water supply tube. This is to prevent it from happening.

This will be explained below based on the drawings. Reference numeral 1 denotes a washing machine frame in which a washing tub 2 and an outer dehydrating tub 3 are arranged side by side, a rotary blade 4 is provided at the bottom of the washing tub 2, and a dehydrating tub 5 is provided inside the outer dehydrating tub 3, respectively. ing. A control box 6 is installed at the rear upper end of the washing tub 2 and outer dehydration tub 3, and is composed of a base 7 with an open front and an operation panel 8 that covers the open front part of the base 7, and includes timers 9, 10, etc. is built-in.

An upwardly bulging portion 11 is provided on the bottom surface of the base 7, and a water supply cylinder 12 is integrally molded into this bulge 11. It protrudes, and a water supply hose 14 connected to a faucet is inserted into the upper end thereof. The lower end of the water supply tube 12 is fitted into the upper end of the approximately L-shaped water supply pump 15 . This pipe 1
A circular flange 17 that forms a water receptor 16 in cooperation with the outer peripheral wall of the upper end of the pipe projects outward from the outer peripheral wall of the pipe 5, and the tip of this flange 17 has a plurality of circular flanges projecting from the inner wall of the bulging portion 11. It is rotatably placed on the support piece 18. That is, the plurality of support pieces 18 constitute a support base for the water supply pipe 15.

A water supply box 19 for receiving water discharged from the lower end of the water supply pipe 15 is attached to the outer bottom surface of the base 7. Reference numeral 20 denotes a claw that elastically engages with an engagement hole 21 provided on the bottom surface of the base 7. The water supply box 19 includes a water supply channel 23 for supplying water from the water supply pipe 15 to the washing tub 2 through a water supply port 22, and a dehydration channel 2 for supplying the water to the dehydration tank 5.
It has 4. Both water supply channels 23 and 24 are separated by a partition wall 25. In addition, in the water supply channel 23 to the washing tank,
A flood portion 26 is provided at a position lower than the upper end of the partition wall 25.

As shown in FIG. 4, a plurality of protrusions 35 are protruded from the upper surface of the circular flange 17 of the water supply pipe 15 at equal intervals. On the other hand, an operation plate 36 is attached to the back surface of the operation panel 8 so as to be movable left and right along this panel, and a part of the operation plate 36 has the same pitch as the projections 35 and engages with the projections 35 as shown in the figure. A plurality of feed claws 37 are provided in a protruding manner.

When the operating plate 36 is moved from left to right along the panel 8 by holding the knob 38 attached to the operating plate 36, the engagement between the protrusion 35 and the feeding pawl 37 changes sequentially, which means that the water supply pipe 15 rotates. do. When the lower end of the water supply pipe 15 is directed toward the water supply channel 23 as shown by the solid line in FIGS. 5 and 3, the water supply port 22
Water is supplied to the washing tub 2, and the water supply pipe 15 is rotated so that its lower end is connected to the water supply channel 24 as shown by the dashed line in FIG.
When the water is directed toward the dehydration tank 5, water is supplied to the dehydration tank 5, and water can be supplied while rotating the dehydration tank to perform rinsing within the dehydration tank.

When water is being supplied to the washing tub 2, if the amount of water coming out of the water supply pipe 15 is too large, it will try to flow from the water supply channel 23 over the partition wall 25 and into the water supply channel 24 of the dewatering tank. Before overcoming the wall 25, the water overflows from the overflowing part 26 into a circular water conduit 27 as shown by the arrow in FIG. 2, and is discharged from a discharge port 28 provided in a part of this water conduit 27. As is clear from FIG. 6, this discharge port 28 is located above an overflow chamber 29 having an overflow port (not shown) provided at the corner of the washing tub 2, and the water that eventually overflows from the overflow portion 26 into the conduit 27 is The water is discharged from the discharge port 28 into the overflow chamber 29 . Therefore, even if the amount of water supplied to the washing tub 2 is too large, the partition wall 2
5, water is not supplied from the condensation channel 24 to the dehydration tank 5, and the clothes that have been dehydrated in the dehydration tank are not wetted. Also, discharge port 28
The water released into the overflow chamber 29 from the overflow cover 3
Since the water is supplied to the washing tub 2 through the large number of water holes 31, no water is wasted.

By the way, if the upper end of the water supply pipe 15 and the lower end of the water supply tube 12 are fitted together with some clearance so that it can rotate easily, if the amount of water supplied is large, this fitting part 3
It is conceivable that water may come out from the control box 6 and splash into the control box 6, wetting the electrical components inside and degrading the insulation.

However, the water supply cylinder 12 is integrally provided with a guide wall 33 that guides the water that has flown out from the fitting portion 32 to the receiver 16, and a drain hole 34 is provided at the bottom of the water receiver 16, so that this water can be drained. Since the drain hole 34 is opened above the water conduit 27, the water that has flowed out from the fitting portion 32 is guided to the water receiver 16 as shown by the arrow in FIG. There is no possibility that water will be discharged from the discharge port 28 into the overflow chamber 29 and scattered into the control box 6. The water discharged into the overflow chamber 29 is supplied into the washing tub 2 through the water passage hole 31 of the overflow cover 30, so that the water is not wasted. Although the water coming out of the outlet 28 may be guided to the outer dehydration tank 31,
In this case the water released is wasted.

Therefore, according to the present invention, even if the amount of water supplied from the water supply hose is large and water overflows from the fitting part between the water supply cylinder and the water supply pipe, there is no risk of wetting the electrical components inside the control box, and the overflow is ensured. This allows the water to be discharged into a washing tub, etc., without wetting the electrical components inside the control box, thereby deteriorating their insulation or shortening their lifespan. Since the water supply cylinder and the water supply pipe can be loosely fitted, the water supply pipe can be rotated with a small force, and the water supply direction can be changed smoothly.
