Description

[Detailed description of the invention] The present invention relates to a washing machine in which laundry can be soaked and placed.

It is well known that if laundry is soaked in water before full-scale washing, dirt will not separate easily and washing can be done more effectively. It has been previously thought that soaking should be done before "washing", etc. However, since the "soaking and leaving" process takes a relatively long time, various existing processes have been set up to do this. It is difficult to add a new process to a washing machine timer device, and for this reason, generally, a washing machine timer device is the main timer device, an auxiliary timer device is provided separately, and a time limit is determined by this auxiliary timer device. "
After the time period ends, the main tie i-device is started to move to "washing" or the like. However, such a device that requires two timer devices has the disadvantage of high cost, and also has the disadvantage of being troublesome to operate since two timers must be operated.

Therefore, the present invention makes it possible to wash and "soak" laundry with a single timer device, thereby making it possible to reduce the cost.
The aim is to provide a washing machine that can also improve operability at the same time.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. First, in FIG. 1, 1 is inserted into a power outlet (not shown) and 4a4! The power supply plug has busbars '2 and 5 connected to both terminals thereof. 4
is a timer device, and is equipped with stroke cam switches 6 to 13 and a reversal cam switch 14, which are opened and closed as shown in the time chart of FIG. 2 in response to 60 rotations of the lever timer motor. In FIG. 2, the hatched area represents the closed state between the contact pieces of the cough switch, and the other blank areas represent open ridges. Also, FIG. 3 shows a program for the timer device 4, and the timer device 4 can be set according to this program. Referring again to FIG. 1, 15 is a drive motor, which has motor coils 15a, 15b and a capacitor 150, and rotates in the forward direction when the forward rotation terminal taK is energized, and when the reverse rotation terminal tbK is energized. It is designed to rotate in the opposite direction. 16 is a water level switch, 17 is a water supply solenoid valve, and 18 is a drainage solenoid valve. Reference numeral 19 denotes a lid switch (not shown) that is linked to opening and closing of the lid. Reference numeral 20 denotes a selection switch device, which includes changeover switches 21 and 22 that are opened and closed in conjunction with the operation of appropriate knobs (not shown). The drive motor 15 is the load. The solenoid valve 17 for water supply, the solenoid valve 18 for drainage, and the timer motor 5 are connected to cam switches 6 to 14. Water level switch 16. Lid switch 19
．． The busbars 2 and 3 are connected via changeover switches 21 and 22 as shown in FIG.

Next, the operation of the above configuration will be explained. First, when performing a normal saving cycle, the selection switch device 20 is operated to selectively close the contacts (o-a) on the normal cycle side of the changeover switches 21 and 22, respectively. When the timer device 4 is set to the "wash" stroke of the saving cycle, the contact between the cam switch 6 and the contact piece (o-a) which is the insufficient water level side contact of the water level switch 16, and the contact piece (o-a) of the cam switch 7. The water supply solenoid valve 17 is energized through the interval, and water supply is started. When the water level of this water supply reaches the specified water level, the water level switch 16 detects this and opens the contact piece (c-a), which is the contact on the sufficiency level side (c-a).
4'b) to close the contact piece (
Due to the opening between o and a3, the water supply solenoid valve 17 is cut off,
Instead, between the contacts (c-b) of the water level switch 16, between the contacts (C-a) of the changeover switch 21, and between the contacts (C-a) of the cam switch 8. The timer motor 5 is energized between the contact pieces (o-a) of the cam switch 10 and between the contact pieces (a-o) of the changeover switch 22, and the timer device 4 starts timing operation. Electricity is supplied to the cleaning motor 15 via the contact pieces (O-a) and then alternately between the contact pieces (c-a) or between the contact pieces (c-b) of the reversing cam switch 14, and a "washing" operation is performed. Do the following. At this time, when the contact piece (ca) of the reversing cam switch 14 is closed, the drive motor 15 is energized to the forward rotation terminal ta and rotates in the forward direction, and the contact piece (c-a) of the reversing cam switch 14 is closed.
b) When the gap is closed, the drive motor 15 is connected to the reverse rotation terminal tb.
It rotates in the opposite direction when energized, and forms a self-reversing swirling water flow. When it becomes "drainage", the cam switches 7 and 12 are switched to open the contact pieces (o-a) and close the contact pieces (c-'b). The drive motor 15 is cut off, and the drainage solenoid valve 18 is energized instead. As drainage progresses and the water level decreases, the water level switch 16 is turned off by the contact piece (c-
b) The contact piece (c-b) of the cam switch 7 is switched so that the contact piece (a-a) is opened and the contact piece (a-a) is closed again.
between the lid switch 19 and the cam switch 12 (c-
b) Continue energizing the drainage solenoid valve 18 through the interval. On the other hand, the timer motor 5 is also continuously energized through the contacts (O-a) of the cam switch 10 and between the contacts (a-o) of the changeover switch 22. Then, when it comes to "dehydration", the cam switch 6, the contact piece (a-a) of the water level switch 16, the contact piece (o-b) of the cam switch 7, the lid switch 19. Between the contacts (O-a) of the cam switch 10, the changeover switch 22
The timer motor 5 is energized through the contact pieces (a-o) of the cam switch 12, and the drain solenoid valve 18 is energized through the contact pieces (c-b) of the cam switch 12. The normal rotation terminals ta of the drive motors 14 are energized to perform dehydration operation. ``Rinse'' is operated in the same manner as ``wash'', followed by draining and dewatering steps in the same manner as above, and at the ``off'' position, the domestic operation of the saving cycle ends and the washing machine stops. The "wash" operation of the wash-only cycle is performed in the same way as the "wash" operation of the save cycle.

Next, the selection switch device 20 is operated to selectively close the contacts (c-b) on the soak cycle side of the changeover switches 21 and 22.

Then, when the timer device 4 is set to the start position of the soak cycle ("Wash" of the saving cycle), the contact between the cam switch 6 and the contact piece (C-a) of the water level switch 16 and the contact piece (0-a) of the cam switch 7 is set. a) The water supply solenoid valve 17 is energized through the interval. Then, as in the "Washing" saving course, when the water level reaches the specified level, the water level switch 16 switches to the contact piece (c).
-b), the water supply solenoid valve 17 is cut off, and the water level switch 16 contacts C0-
b), the timer motor 5 is magnetized between (c and b) of the changeover switch 21 via the cam switch 9, and the reversing cam is further passed between the contacts (0 and b) of the cam switch 11. The drive motor 15 is energized via the contact piece (○-a) or the contact piece (c-b) of the switch 14. In this case, the cam switch 11 is activated for a long time t!, as shown in FIG. (for example, 10 minutes) between the contact pieces (c and b). Therefore, in this soak cycle, a long time t
! During this period, only the timer advances, and the drive motor 15 is energized as described above for a short period of time tl to perform stirring operation. In addition, the timer device 4 is "drainage" of the saving course,
"Dehydration", "Rinse".

The soak cycle continues in a similar circuit in the "off" position. When the soak cycle is completed and the standard course "wash" position is reached, the cam switch 6 and the contact piece (Q-b) of the water level switch 16 are opened.

Between the contacts (c and b) of the changeover switch 21, the cam switch 9
The timer motor 5 is energized via the contact piece (O-a) of the cam switch 11, and the contact piece (C-a) of the cam switch 8 and cam switch 12 is further energized to the reversing cam switch 14.

The drain solenoid valve 18 is energized via the cam switch 8. The timer motor 5 is energized via the contacts (a-C) of the cam switch 11 to continue the drainage operation. Then, when "dewatering" is started, the cam switch 13 is closed, and the drive motor 15 is energized to perform the dehydration operation.

"Rinse" is operated in the same way as "Wash", followed by the same drain and spin steps as above, and then the same steps of "Rinse", "Drain", and "Spin", and then "Cut". '', the standard cycle automatically completes and the washing machine stops.

In addition, when operating the standard cycle from the beginning without going through the soak cycle, when the selection switch device 20 is on the soak cycle side, the washing machine is operated with the same configuration as above. On the other hand, for the standard cycle from the beginning when the selection switch device 20 is operated to the normal cycle side, first the timer device 4 is set to the "wash" stroke, and the contact piece (C) of the cam switch 6 and water level switch 16 is -a), the water supply solenoid valve 17 is energized through the contacts (o-a) of the cam switch 7. When the specified water level is reached, the cam switch 6

Perform dehydration operation. "Rinse" means "wash"
The above operation is repeated thereafter to complete the standard cycle.

It is possible to select one of the standard cycle, wash-only cycle programs, and soak cycle program, and in particular, by doing so, the soak cycle time can be made much longer.

As is clear from the above description, the present invention requires only one timer device and a selection switch device to select between washing and soaking the laundry. Since the selection switch device is cheaper and easier to operate than a timer device, it can be made cheaper overall and has improved operability compared to the conventional method that required two timer devices. It is effective.
