33 is a water supply electromagnetic valve arranged inside the mounting plate 27, and the water inlet 33affi is connected to a water faucet serving as a water source via a hose (not shown), and the water outlet 33b')\equipment storage section 28
It is connected via a hose 35 to a water inlet 34 formed in the recessed upper surface 24b of the upper container 24 that constitutes the bottom of the container.

36 is a water outlet formed at the bottom of the lower container 25, 37 is a water injection valve device that opens and closes this water outlet 36, and this water injection valve device 37 includes a valve body 38 and a valve whose lower end is connected to this valve body 38. A rod 39, a compression spring 40 that is wound around the valve rod 39 and always biases the valve body 38 in the closing direction, and an upper container 24.
The valve body 38 is disposed on the depressed upper surface 24b of the valve body 38 via the valve stem 39.
It consists of an electromagnet 41 that operates to open.

42 is an air trap integrally formed on the lower surface of the depressed upper surface 24b of the upper container 24; 43 is a water level switch disposed inside the panel board 32 together with a timer device 44;
This water level switch 43 is in communication with the air trap 42 via a tube 45.

Reference numeral 46 denotes an air vent hole, which is formed inside the bulging portion 26.26. If water overflows from the air vent hole 46 due to a malfunction or the like, the water will be guided to the equipment storage portion 28 and drained to the entrance/exit 2.
9 into the rotating tank 13.

Next, the operation of the above configuration will be explained.

First, the laundry along with the detergent is passed through the inlet/outlet 29 into the rotating tub 13.
At the same time, leave the water faucet open.

Next, when the timer device 44 is set, the freezing solenoid valve 33 is first energized and opened, thereby supplying tap water into the water storage container 23.

Then, when a predetermined amount of water is stored in the water storage container 23,
The water supply solenoid valve 3
3 is cut off and operated to close, stopping the water supply to the water storage container 23.

Thereafter, the electromagnet 41 of the injection valve device 37 is energized and the valve body 38 is opened, so that the water in the water storage container 23 is injected into the rotating tank 13 through the water outlet 36.

Then, when all the water in the water storage container 23 is supplied into the rotating tank 13, the electromagnet 41 of the water injection valve device 31 is cut off, the valve body 38 is operated to close, and the motor 11 is started to operate the stirring blade. 19 is rotated, and the detergent washing operation is performed as described above.

When this detergent washing operation is completed, the rotating tank 13 is first driven to rotate by the motor 11, and the water in the rotating tank 13 is pumped up by the centrifugal force accompanying the rotation and flows into the water collection chamber 5 from the discharge path 18. discharged, drain port 21 and drain hose 22
is discharged from the aircraft via the

After the water in the rotary tub 13 is substantially discharged, the laundry is dehydrated, and the water is discharged outside the machine in the same manner as described above.

During the dehydration operation involving such drainage, water is stored in the water storage container 23 in the same manner as described above, and after the dehydration operation is completed, this water is supplied to the rotating tank 13 in the same manner as described above, and then the rinsing operation is started. After that, a dehydration operation similar to that described above is performed, and thus the washing operation is completed.

As described above, according to this embodiment, since the water storage container 23 is arranged at the upper part of the upper box body 3 so as to close the opening thereof, a lid frame for closing the upper opening of the upper box body 3 is separately provided. There is no need.

Moreover, in the structure in which the water storage container is provided in the upper box body 3 and the opening of the upper box body 3 is closed with a separate lid frame, wasted space inevitably occurs between the lid frame and the water storage container. In this embodiment, such a space does not occur (and the entire structure can be made smaller in the vertical direction).

Further, an equipment storage section 28 is formed in the upper container 24, and a water supply solenoid valve 33. Electromagnet 41 of water injection valve device 37. Since the water level switch 43, timer device 44, etc. are provided, there is no need to provide a separate operation box. Water supply solenoid valve 33, which is highly related to
It is possible to directly attach devices such as the water storage container 23 to the water storage container 23, thereby providing convenience in terms of piping, wiring, etc.

Furthermore, as in this embodiment, the step portion 24affi of the lower container 24
If it is placed on the opening periphery of the upper box body 3, a special structure for supporting the water storage container 23 becomes unnecessary.

In addition, by placing the lower surface of the lower container 25 on the opening periphery of the upper box 3, the height of the upper box 3 can be reduced, and material costs can be reduced.

Similarly, in the above embodiment, water is supplied from the water source to the water storage container 23, the amount of water necessary for the washing operation is measured, and then water is poured into the rotating tank Vc13. In order to shorten the time, during a washing operation, part of the amount of water required for the next washing operation is supplied to a water storage container and stored there, and during water injection, water is supplied directly from the water source to the rotating tank, and at the same time water is also supplied from the water storage container. It is also possible to configure it to inject water.

In addition, the invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with various changes without departing from the spirit thereof.

As explained above, the present invention is provided with a water storage container, and has a configuration in which the water storage container is disposed in the upper part of the outer box so as to close the opening thereof, and an equipment storage part is formed in a predetermined part of the water storage container. This makes it possible to reduce the number of components by eliminating the need for a separate lid frame and operation box, and allows equipment to be rationally assigned in relation to the water storage container. Avoid creating wasted space like (
It is possible to provide a washing machine that can be downsized as a whole.
