Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention controls processes such as washing and rinsing in a washing tank using an automatic time switch, and controls spin-rinsing processes in the spin-drying tank, that is, spin-drying, pausing, and water supply using a spin-drying timer. This relates to electric washing machines operated by

Conventional structure and its problems The cycle display on the washing side of conventional washing machines of this type is as follows:
The entire 360-degree range is divided into the standard automatic course, economical course, washing only, and draining only, and the display angle when setting the automatic time switch will inevitably be small, and it will not be possible to set it halfway. It was difficult.

Furthermore, in the conventional cycle display configuration, especially when executing a washing-only process, it is necessary to set the automatic time switch to the starting position of the washing-only process. Spin rinse is
It is preferable that the rinsing process can be performed easily after washing, since the rinsing effect can be obtained with a small amount of water by performing the rinsing process instead of rinsing at the washing side. However, as mentioned above, if only washing is set after the automatic cycle display, etc., it takes time to make only washing occur, and as a result, the usage of spin rinse inevitably tends to decline. It was easy to do.

OBJECTS OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to enable the cycle display in the automatic time spin on the washing side to fully utilize the spin rinse on the dehydration side.

Structure of the Invention In order to achieve the above object, the present invention provides an automatic time switch that performs washing, draining, rinsing, etc. on the washing tub side;
It is equipped with a dehydration timer that repeatedly performs dehydration, pause, and water supply on the dehydration tank side, and the cycle display on the automatic time switch can be used for washing and draining.

The system is configured to have a series of automatic courses such as washing, draining, rinsing, etc., which makes it easy to perform only washing, and furthermore, it is possible to perform spin-rinsing on the dehydration side after washing only. It can be implemented easily.

Description of examples Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows the configuration of a two-tub washing machine, in which 1 is a body, and an operation box 2 is arranged at the top. The operation box 2 is equipped with an electromagnetic water supply valve 4 and an end buzzer 6 that are controlled by an automatic time switch 3 on the washing side, and further equipped with a water flow strength changeover switch 6 and a pressure switch 7 for controlling the water level. There is. A dehydration timer 8 for controlling dehydration time is also attached.

Inside the body 1 is a washing motor 9. A dewatering motor 10 is attached, and the washing motor 9 rotates a pulsator in the washing tub via a transmission belt. Also,
A dewatering head 11 is connected to the rotating shaft of the dewatering motor IC1, and is rotated at high speed to perform dewatering.

FIG. 2 shows the configuration of an electric circuit, and the operation of this circuit is performed according to the operating program of the automatic time switch 3 shown in FIG. The circuit configuration and its operation will be explained.

When automatic time switch 3 is set to "Wash", power supply 1
2, through the overflow prevention pressure inlet 13, the contact T1 of the automatic time switch b - the NCll of the pressure switch 7
The electromagnetic water supply valve 4 on the a-washing side of the l-contact T5 is energized. When the electromagnetic water supply valve 4 is energized, water enters the washing tub from the faucet 14 through the pressure hose 15. When the water in the washing tub reaches a predetermined water level, the contact of the pressure switch 7 is switched from the NC side to the No side. For this reason, the pressure switch 7 No.
side - b of contact T6 - T7a - water flow switching Suinochiro automatic reversal contact T8 or T9 - capacitor C1 - washing motor 9
is energized and washing is performed.

At the same time as the pressure Kasinochia switches to the No side, the T
Since the timer motor TM is energized from 6b, the automatic time switch 3 moves as shown in the program shown in Figure 3.

Reference numeral 16 denotes a drain stop switch, and when this switch is set to 82, the end buzzer 5 sounds at the end of the washing cycle, and at the same time the electromagnetic water supply valve 4 and the washing motor 9 are cut off, so that contacts T5a and T7a are turned on. It is designed to turn off as soon as it enters the contact T2b of the end buzzer 5.When the drain stop switch 16 is set to 81, the end buzzer 5 goes off during washing.
The system moves on to the next ``drainage'' without making a sound.

``Drain'' is energized to the automatic time switch 30T1a, the drain stop switch 16's Sl "3a" 4a, and the drain solenoid valve 17. Contact “6a” to timer motor TM
energized and the program is transferred.

When approaching the end of the water, the end buzzer 6 will sound.

At this time, the contacts of the automatic time switch 3 are such that T4 (a) is turned off and T7 (b) is turned on. Therefore, when the end buzzer 6 sounds, the power to the drain electromagnetic valve 17 is cut off. When the end buzzer 5 finishes sounding, the automatic time switch 3iI'i is stopped.

Next, switch from ``Off'' to ``Wash'' on the automatic course, and perform the same operation as the ``Wash'' operation described above.

However, regardless of the drain stop switch 16,
"The drain pump operates in the same way as the drain operation described above, but when the water is not drained, such as when the drain hose is left standing, the automatic time switch 3
The contact T3 a becomes OFF midway. Normally, even if T3 a turns OFF midway, the flow of electricity will be N because the pressure switch 7 is discharging water.
Switched from O to NC. Therefore, even if the contact a of contact T3 is broken, the drain solenoid valve 17 is connected to the NC side of the pressure switch 7.
Then, the timer motor TM is energized, but since the pressure switch 7 remains in the No position, the program does not proceed any further.

Next, when the mode shifts from "Drain" to "Rinse", the automatic time switch 3 energizes the electromagnetic water valve 4 from contact T1 b - pressure switch 7 NC side - T5 a, and water enters the washing tub. When the water reaches the specified level, the pressure switch 7 changes from NC to N.

Washing motor 9 is energized from T6's b-T7's a-Water flow selector switch 6-T"! or T9 to perform rinsing. At this time, the rinsing switch is turned on. If the switch 18 is ON, the T b-T5 a-electromagnetic water supply valve 4 is energized, and water enters the washing tub even if the pressure switch 7 is closed to the NC side.After such an operation , draining and rinsing are repeated, and in the final rinsing, the same operation as rinsing is performed, but if the drain stop switch 16 is set to the 82 side, the end buzzer 5 will sound when the rinsing is nearing completion. After the rinsing is completed, the next drain starts and the operation is stopped.At the same time as the termination buzzer 5 sounds, the electromagnetic water supply valve 4 and the washing motor 9 are de-energized.

If the drain stop switch 16 is set to the 81 side, when the final drain starts, the drain electromagnetic valve 17 is energized and drains, and when the drain is nearing completion, the end buzzer 5 sounds and indicates "off". At the same time as the termination buzzer 5 sounds, the power to the drain solenoid valve 17 is cut off.The drain stop switch 16 is set to 8.
If it is on the 1 side, the end buzzer 5 will not sound during the final rinse. A series of programs is performed as described above.

Next, the dehydration side will be explained. Since the dehydration side is configured to perform dehydration and rinsing using the dehydration tank, the dehydration timer 8 runs according to the operating program shown in FIG. This program will be explained below.

Place laundry that has been washed but not yet rinsed into the spinner 11, such as laundry that has been washed and drained as shown on the automatic time switch 3 shown in Figure 5, and set the spinner timer 8. do.

In ``Dehydration°'', contact a of contact T1 of dehydration timer 8
The dewatering motor 10 and the capacitor C2 are energized through the a of T2, and the dehydrating paddle 11 rotates at high speed, squeezing the laundry and discharging the detergent liquid to the outside. Next, at 'rest', T2 b is applied and the power to the dehydration motor 10 is cut off, but T
A half-wave direct current is applied to the dehydration motor 10 by a diode 19 connected to the b side of the dehydration motor 10 to generate a braking force and stop the dehydration blade 11.

Next, T3 (b) of the water supply valve is closed and the water supply valve 4' on the dehydration side is energized, and water enters the dehydration valve 11 and is contained in the laundry.

Next, add a from T2 and put it in the dehydrator, then wipe it on the laundry.
Squeeze out the water still. By repeating this, dehydration and rinsing is performed, and dehydration is completed in the final dehydration. The contact T1 of the dehydration timer 8 switches from the a side to the b side when water is supplied after the ``rest'' of ``rinsing l''.
If the rinsing changeover switch 20 is OFF, it will remain stopped at the time when the body has stopped. This is because the rinsing liquid is added in this stopped state. If the rinse input changeover switch 20 is ON, the final dehydration is performed, and the end buzzer 6 is energized to end the process.

When the dehydration timer 8 is in T1b, if the automatic time switch 3 is off, the drain solenoid valve 17 is set to the dehydration timer T1b - automatic time switch 3 Tb-
Electricity is applied through a of T4, and residual water is discharged.

The end buzzer 5 is used for washing and dehydration, so while the end buzzer 5 is energized, the automatic time switch 3 only operates the timer motor TM and does not operate other loads. It has become.

The electromagnetic water supply valve 4 and the dewatering side water supply valve 4' are composed of electromagnetic valves having two coils, two outlets, and one inlet so as to supply water to the washing side and the dehydrating side, respectively.

As is clear from the cycle display configuration shown in FIG. 5, the automatic time switch 8 is divided into washing, draining, off, and automatic courses. This is because the dehydration side is configured to perform dehydration and rinsing, and after washing is completed, the laundry before rinsing is transferred to the dehydration basket side, making it easier to perform dehydration and rinsing.

In FIG. 2, reference numeral 21 denotes a safety switch which is interlocked with a lid that can freely open and close the upper opening of the dehydration tank housing the dehydration drum 11, and cuts off the power to the dehydration motor 10 when the lid is opened.

Effects of the Invention As is clear from the above embodiments, according to the present invention, the laundry that has been washed under the control of an automatic time switch on the washing side is immediately processed on the spin-drying side under the control of a spin-drying timer. The laundry can be rinsed with a spin rinse, increasing the degree of utilization of the spin rinse, and making it easier to obtain the timing when moving the laundry from the washing side to the dehydration side.

Furthermore, the automatic course is executed after the washing, draining, and turning off processes, so there is no hassle in starting the washing, draining, and turning off processes, and the display angle of the automatic time switch can be increased. This has the advantage of being easy to see and set.
