[Detailed description of the invention] This invention is an automatic washing machine that automatically controls a series of processes such as washing, draining, rinsing, etc. using a program timer that has multiple cam switches. The purpose is to control the delicate water level, which cannot be controlled with a switch, by timed water supply using a program timer.

Conventionally, the water level control of the washing tub of this type of automatic washing machine is as follows:
This is done with a water level switch consisting of a pressure switch.
Previously, high water level and low water level were detected, but due to the operating characteristics of this water level switch, it is difficult to distinguish and detect unless there is a certain level difference in water level. In cases where there is no water level, water levels higher than the high water level could not be detected by this water level switch. This was because the water level, which was higher than the high water level that could be detected by the water level switch, would rise above the overflow port and overflow.

本考案は、例えば高水位では少し水が不足する
ような毛布等の大きな物を洗濯する場合に、高水

したものである。
The present invention makes it possible to obtain a water level that is higher than the high water level and lower than the overflow port, for example, when washing large items such as blankets for which there may be a slight shortage of water at a high water level.

The present invention will be explained below based on a drawing showing a so-called dehydrating washing machine having a washing tub that also serves as a dehydrating tub. Figure 1 shows an electric circuit, where 1 is a water supply solenoid valve 2 that opens when excited and supplies water to a washing tub that also serves as a spin-drying tub.
3 is a water supply solenoid valve that opens when energized and supplies hot water to the washing tub; 3 is a water level switch that detects the water level in the washing tub and switches from normally closed contact 4 to normally open contact 5 when a specified water level is reached; 6 is a drive motor that drives the washing tub and rotary blades, 7 is a starting capacitor for this motor, and 8 is a solenoid that operates a drain valve that drains the liquid in the washing tub. When this solenoid 8 is energized, the drain valve opens and drains water. The brake device for the washing tub is operated to release the brake, and the clutch device is simultaneously operated to transmit the rotation of the drive motor 6 not only to the rotary blades but also to the washing tub. 9 is a safety switch that opens when the top cover is opened, and 10 is a power plug.

11 to 18 are cam switches built into the program timer, and these cam switches 11 to 18
is controlled to open and close as shown in the program shown in FIG. 2 by a group of cams (not shown) which are intermittently rotated by a certain angle every minute in this example by a timer motor 19. Similarly, auxiliary cam switches 20 to 23 are built into the program timer, and in this example, opening and closing are controlled by a group of auxiliary cams (not shown) that rotate continuously once per minute as shown in the program shown in FIG. The auxiliary cam switches 20 to 22 are used to control the rotation time of the rotor blades during the washing process, and when the drive motor 6 is energized via 20, the strong water flow is generated for the longest rotation time, and in the case of 21, the rotation time is the shortest. The water flow is weak and weak, and one can be selected using the water flow changeover switch 24. In the case of 22, the water flow is intermediate, and it acts only when a manual select switch 29, which will be described later, is closed. 25 is a rinse selector switch, and when this switch 25 is closed,
During the final rinsing step, overflow rinsing (rinsing in which water is continued to be supplied regardless of the water level switch 3) is performed.

26-30 are "fully automatic", "semi-automatic", and "wash only"
This is a manual select switch that is controlled to open and close as shown in the operation diagram in FIG. 4 by selectively pressing the course button labeled "Blanket Washing."

Next, the operation will be explained. When the "Full automatic" course button is pressed, the a contacts of cam switches 11 and 13,
Normally closed contact 4 of water level switch 3, cam switch 18
The water supply solenoid valve 1 is energized through the a contact point of the cam switch 16 to supply water to the washing tub, and the hot water supply solenoid valve 2 is energized through the a contact point of the cam switch 16 to supply hot water. When the water level has reached the specified water level and the water level switch 3 switches to the normally open contact 5, water supply and hot water supply are stopped, and the timer motor 19 is driven via the a contact of the cam switch 15, and the b contact of the cam switch 17 is switched to the select point. The drive motor 6 is energized via the auxiliary cam switch 20 or 21 selected by the switch 28 and the water flow selector switch 24 to rotate the rotor blades and start the washing process. Even when the cam switch 13 switches to the b contact after the washing process is completed, the load continues to be energized via the select switches 26 and 27, and the program shown in FIG. 2 is carried out until the final dewatering process.

When the "wash only" course button is pressed, the select switch 26 is open, so when the washing process is finished and the cam switch 13 switches to the B contact, the load such as the timer motor 19 will not be energized. It will be cut off and operation will stop.

Operation will be stopped.

By the way, if you want to wash a large item such as a blanket, press the "Blanket Wash" course button. Then, water and hot water are supplied up to the specified water level in the same way as when the "fully automatic" course button is pressed, but even when the specified water level is reached and the water level switch 3 switches to the normally open contact 5, the auxiliary cam switch The b contact of the auxiliary cam switch 23 is closed via the b contact of 23, the a contact of the cam switch 14, and the select switch 30.
Water supply solenoid valve 1 is energized and water supply is added for only 10 seconds. Not only the water supply but also the hot water supply solenoid valve 2 is supplied via the a contact of the cam switch 18 and the a contact of the cam switch 16.
Since it is energized for 10 seconds, hot water is added. One minute after the water level switch 3 switches to the normally open contact 5, the a contact of the cam switch 14 opens, so even if the auxiliary cam switch 23 closes again to the b contact, no water or hot water is supplied.

Therefore, washing can be performed using a larger amount of water than the specified water level determined by the water level switch 3. This additional amount of water is difficult to detect with a water level switch, and is the amount that lowers the water level below the overflow port, allowing you to fill the washing tub with as much water as possible and do as much laundry as possible. I make it possible to wash things.

This additional water supply and hot water supply is not only necessary for the washing process, but also for the first rinsing process.

As described above, according to the configuration of the present invention, delicate water level adjustments that cannot be controlled by the water level switch can be made after the water level switch switches to the normally open contact and water supply via the normally closed contact of the water level switch ends. This is done by supplying additional water using the B contact of the auxiliary cam switch 23, which is built into the program timer and closes for a short period of time, so that as much water as possible is supplied to the washing tub without overflowing from the overflow port, and the blankets, etc. This allows large laundry items to be washed without increasing the size of the washing tub. Further, the select switch 20 allows selection of whether or not to supply additional water, making it easy to use.
