[Detailed Description of the Invention] This invention relates to a water supply device for a washing machine, and more particularly to a water supply device that can display an excess amount of water supplied from a tap or the like per unit time.

In the figure, reference numeral 1 denotes an outer casing of a washing machine, in which a washing tank 2 and a dehydration receiving tank 3, each of which has an open top surface, are placed side by side. The washing tank 2 is equipped with a water flow generator, ie, a pulsator 5, which is driven by a motor 4, and the dehydration receiving tank 3 is equipped with a dehydration basket 7, which is driven by a motor 6 and has an open top. A drain hose 8 is connected to the bottom of the washing tank 2 via a drain valve 9 and to the bottom of the dewatering tank 3, respectively.

Reference numeral 10 denotes a control box containing a time switch for controlling the motors 4 and 6, and is located at the rear upper part of the washing tank 2 and the dewatering tank 3. The control box 10 includes a lower frame having a bottom wall 10a and a rear wall, and a cover 10b covering the upper and front surfaces of the lower frame.
The bottom wall 10a has a cylindrical wall 11 that is partially raised on its upper surface and is open downward, and a gutter-like wall 12 that is open in the same direction. It has a water supply port 13 that protrudes into a cylindrical shape. The cover 10b has a through hole 15 at the bottom of a recess 14 formed above the cylindrical wall 11, which opens the upper end of the water supply port 13 to the outside.

Reference numeral 16 denotes a water supply hose led from a water source such as a water faucet, and a fitting 17 is fitted and attached to the tip of the hose.
The joint 17 is detachably connected to the water supply port 13 through the through hole 15.

Reference numeral 18 denotes a gutter-like member with an open upper surface that forms a water channel for supplying water to the washing tank and the dewatering basket. It is attached by being hooked into a hole 20 in the gutter-like wall ceiling. The gutter-like member 18 is a partition wall 18 located below the cylindrical wall 11.
Divide the inside of the gutter-like member into two in the longitudinal direction by a,
First and second water channels 21 and 22 are formed. The first water channel 21 extends above the washing tank 2, has an opening 21a on the lower surface of its tip, and is connected to the upper end of a groove 23 formed in the vertical direction on the inner surface of the washing tank 2 through the opening 21a. The groove 23 is covered with a plate 24 leaving the lower end portion, and the first water channel 21
The water supplied from the tank is guided to the washing tank from below the normal washing water level.

The second water channel 22 has one side wall 22a facing into the washing tank from the partition wall 18a located above the washing tank 2, and a top plate that covers the top surface of the dewatering tank 3 and has a clothes input port 25a. The opening 22b extends along the lower surface of the dewatering basket 25, and has a tip opening 22b facing into the dehydration basket 7 from diagonally above.

26 is a member for switching the water supply between the first water channel 21 and the second water channel 22, which has a cup shape with an open top surface and a circular flange 26a on the outer periphery, and has a fan-shaped through hole 26b at an eccentric position on the bottom surface. . The switching member 26 is inserted into the cylindrical wall 11 from below, and is rotated around the vertical axis by sandwiching the flange 26a between an elastic claw 27 provided inwardly projecting from the cylindrical wall and the ceiling surface of the cylindrical wall. Rotatably held.
Reference numeral 28 denotes an operation knob for rotating the switching member 26, and a cylindrical portion 26c protruding from the outer periphery of the switching member 26.
The control box 10 protrudes from the front surface of the control box 10 through window holes 29 and 30 formed long left and right in the front surface of the cylindrical wall 11 and the cover 10b, respectively. The window hole 29 of the cylindrical wall 11 has protrusions 29a spaced from both ends thereof at a distance corresponding to the width of the cylindrical portion 26c, and the cylindrical portion 26c is placed in the position where the operating knob 28 is swung to the right or left end. Latch.

When the operation knob 28 is operated to the right or left, the through hole 26b of the switching member 26 crosses above the partition wall 18a and faces the first or second water channel 21, 22. Therefore, water supplied from the water supply hose 16 connected to the water supply port 13 is selectively supplied to the washing tank 2 or the dewatering basket 7 via the first or second water channel 21, 22.

31 is a switching member 26 in each water channel 21, 22.
It is a water flow buffering sponge disposed at a position facing the through hole 26b, and is attached to the pin 32 protruding from the bottom surface of the gutter-like member 18. This sponge 31 buffers the water flow that falls to the bottom of the channels 21 and 22, but if the flow rate is large, the water rises along the side walls and may eventually overcome the side walls and overflow to the outside. For this reason, the first waterway 21
At the end near the partition wall 18a, the switching member 26
Walls 33, 33 extending substantially parallel to the side wall are provided closer to the side wall than the lower position of the through hole 26b, so that the water rises up along the wall, and even if the water goes over the wall, it does not flow outside the side wall. I try not to overflow. The wall 33 does not extend all the way to the opening 21a, but instead connects a narrow channel between the wall 33 and the side wall with the main part of the first channel to the opening 21a.

Although some water climbs up and exceeds the partition wall 18a, a weir 34 is provided at the lower edge of the tip opening 22b to prevent the water from falling into the dewatering basket 7. This water flows through a hole 3 provided at the bottom of the second water channel 22 so as to open between the dehydration basket 7 and the dehydration receiving tank 3.
It is discharged from 5.

Although it is permissible to provide the second water channel 22 with a wall similar to the above-mentioned wall 33, since a large amount of water is not supplied into the dewatering basket 7, such a wall is not required in many cases.

Reference numeral 36 denotes a hole for indicating excess water to be supplied to the washing tank 2, and is formed so as to be cut out from the lower end of the side wall to the bottom surface of the front side of the first water channel 21 facing into the washing tank. The first water channel 21 surrounds this hole 36.
A box-shaped wall 37 is formed protruding from the bottom wall along the side wall. The upper end of the box-shaped wall 37 is lower than the side wall of the first water channel 21, and furthermore, the upper end 37a of the box-shaped wall 37 is located on the upstream side.
is lower than other parts. The amount of water supplied to washing tank 2 per unit time is determined by the first
This appears as the height of the water level in the waterway 21.
It is okay to supply as much water as possible per unit time to fill the washing tank 2, but when the water level exceeds the appropriate water supply amount for overflow rinsing, the water level will rise to the box-shaped wall 3.
7 and falls from the hole 36 into the washing tank, indicating that the amount of water supplied per unit time is excessive. The worker can see this and turn off the water faucet.

Reference numeral 38 denotes a hole for indicating excess water to be supplied to the dewatering basket 7, and is formed in the side wall 22a of the second water channel 22 facing the washing tank 2 so as to be cut out from the upper end.
A wall 39 is formed on the downstream side of the hole 38 and projects inward from the side wall 22a so as to intersect with the water flow direction. A large amount of water is not required to be supplied to the dehydration basket 7 since the water is soaked into the clothes to be dehydrated and rinsed. When the water supplied to the second water channel exceeds a predetermined amount, that is, when the water level in the second water channel exceeds a predetermined value, the water flow that hits the wall 39 is guided from the hole 38 to the washing tank 2. When the worker sees this, he can adjust the amount of water supplied by turning the water faucet until no water comes out of the hole 38.

As described above, this invention indicates excess water supply by the water leaking outside over the box-shaped wall due to the rise in water level in the waterway, so it is possible to reduce wastage of water. can. Moreover, the structure is such that the water flowing along the inner surface of the side wall of the gutter-like member hits the box-shaped wall, and the water level rises, causing the water to fall over the box-shaped wall, for example. As shown in the previous Utility Model Application Publication No. 18972/1983, excessive water supply can be detected more accurately than when a gutter-like member is simply provided with a cut-out overflow port in a part of the side wall. There are effects that can be displayed.
