Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a control device for a dehydrating and rinsing device that supplies water to a rotatable dehydrating tank and performs so-called spin rinsing.By controlling the dehydrating and rinsing cycles, troublesome operations are not forced. Then, softener, rinse agent, etc. are added.

In conventional two-tub washing machines in which rinsing is performed on the dehydration tank side, it is necessary to supply water to the dehydration tank. Normally, water is supplied to this dehydration tank by connecting the water faucet with a water inlet or electromagnetic water valve installed on the washing machine body, and connecting the water inlet or the outlet side of the electromagnetic water valve with a hose, etc. A method was adopted that connected to the aquarium.

Furthermore, when rinsing is performed on the washing tub side, conventionally, a fabric softener and a rinse agent have been added to the washing tub filled with water during the final rinse.

However, in dehydration and rinsing equipment that performs rinsing in a dehydration tank, water is rarely stored in the dehydration receiver, and it is common to run an automatic cycle that repeats water supply, dehydration tank rotation, stop, water supply, etc. in sequence. It is. For this reason, when using a fabric softener, be sure to check the timing immediately before water is added during the final rinse cycle of the dewatering cycle.
At this point, it must be fed into the soft finish 6jk dehydration tank.

That is, fabric softener 1 must be added when rinsing is nearly complete. At the point when the detergent is soaked, the softening agent will be rinsed away as the detergent is further rinsed, and when the detergent is rinsed and washed,
It is necessary to repeat the water supply again, resulting in double effort.

Furthermore, in dual-tub washing machines that perform rinsing on the spin-drying side, it is normal for the washing machine to automatically switch to the spin-drying process immediately after the rinse is completed, and when the washing machine is not used all the time, the spin-drying process is complete. Once the fabric is dry, you can add water again to add the fabric softener, or you can return the dehydrated and rinsed clothes to the washing tub filled with water, soak them all in the fabric softener, and then refill the fabric with water. This requires a very labor-intensive operation such as dewatering, which is inconvenient in use.The present invention provides an input means for inputting the softener, as well as ``Water supply ++, u Dewatering'', and ``Stop''. °.

, °゛Water supply゛゛... are controlled by an automatic cycle all timers that repeat, and before the last cycle of the multiple cycles, the timer is stopped or the timer is automatically shifted without doing this. Either of these can be selected using a changeover switch.

By making the selection possible using the switch, for example, if you want to add fabric softener, set the switch to the use side for all fabric softeners, and then turn on the timer before the final "water supply" step. Check the display etc. to confirm that it remains stopped, then add the fabric softener using the feeding means, and then set the changeover switch to the continuous (automatic transition) side, and the automatic cycle will start the subsequent steps. If you do not use fabric softener, if you set the changeover switch to continuous mode from the beginning, all cycles will automatically proceed as usual.

Hereinafter, one embodiment of the present invention will be described with reference to the accompanying drawings. In the figure, 1 is the main body of the washing machine, 2 is an operation box placed at the rear of the upper part of the main body 1, and 3 is a resin tank provided inside the main body 1, which is connected to a washing tub 5 with a pulsator 4 arranged at the bottom. It consists of an integrated dewatering receiver 6.

Reference numeral 7 denotes a dehydration tank rotatably arranged in the dehydration receiver 6, which has a large number of dehydration holes 8 on the peripheral wall, and the bottom of which is connected to a dehydration motor 9.
It is connected to the rotating shaft 10 of.

11 is a drain hole provided at the bottom of the dehydration receiver 6, and the drain hose 1
The drain hose 12 is connected to a drain hose (not shown) on the side of the washing tub 5, and is connected to a drain hose (not shown) outside the machine.

Reference numeral 13 denotes a timer for controlling the dewatering side provided on the front of the operation box 2, which controls the process of supplying water into the dehydration tank 7, the process of rotating the dewatering motor 9 to perform dehydration after this water supply, and the process of dewatering the dewatering process f.
The step of stopping ik for a predetermined period of time (hereinafter referred to as ``water supply'', ``dehydration II, II stop'') is defined as one cycle, and a program is controlled to repeat this cycle.

Furthermore, the number of repetitions can also be controlled.

Reference numeral 14 denotes a dehydration cage detachably arranged at the upper opening of the dehydration tank 7 to prevent clothes from flying out.

It communicates with a stopper (not shown), while the outlet of 15a communicates with the interior of the washing tub 5 via a water supply hose 17. Also,
The outlet of the other 15b of the electromagnetic water supply valve 15 is connected to the water injection hose 18.
Water can be injected into the dewatering tank 7 through a water supply path such as a substantially horizontal portion of the trifurcated pipe 19 having a substantially inverted T shape, and a water injection nozzle 2o.

Reference numeral 19a denotes an inlet pipe located approximately in the vertical direction of the trifurcated pipe 19, and the inlet pipe 19a is connected at an angle of inclination θ so that negative pressure is generated inside the inlet pipe 19a when water is passed through the water supply route. Alternatively, a partition wall 19b is provided so that a negative pressure is generated in the inlet pipe 19a, and a connected state is established that exhibits an aspirator effect.

21 is a pipe-shaped part 21 connected to the inlet pipe 19a at the lower part.
af: The approximately funnel-shaped receptacle is a plate, and is connected to the approximately concave slot 22 formed in the operation panel 2a on the front surface of the operation box 2. The tray 21 is separate from the input port 22 and is separate therefrom. Note that 23 is a dehydration lid that covers the upper opening of the dehydration tank 7 so as to be openable and closable.

Next, the electrical configuration on the dehydration side will be explained with reference to the electrical circuit diagram in FIG. In FIG. 3, 24 is a lid switch that opens when the dehydration lid 23 is opened, and 25 is a changeover switch, the operation switch of which is exposed on the front surface of the operation panel 2a, as shown in FIG.

26 is a capacitor, and 27 is a buzzer.

The changeover switch 25 is for selectively switching between ``continuous course'' and ``finishing course'', and in the former, a plurality of consecutive cycles each consisting of ``water supply TI, +11 dewatering IT, and I+stoppa'' are used. The timer 13 is activated so as to execute the water supply in the last cycle among the plurality of cycles.
Stop the operation of the timer 13 before .

This will be explained in further detail. When stopping the timer 13 just before the water supply in the final cycle described above, if the contact of the changeover switch 25 is closed to the B side in advance, the main contact T1 of the timer 13 is turned on just before the water supply, and the final water supply is completed. The hour contact T2 is off, and the timer mode TM is stopped.

Next, when the contact of the changeover switch 25 is closed to the A side, even if the final water supply contact T2 is turned off, the tie 7
M is turned on and automatic operation starts again. After this, if the contact T4 of the timer 13 is turned on, the other side 15a of the electromagnetic water supply valve 15 is opened, and water is supplied into the dehydration tank T via the water supply path.

This water supply time limit is set to a certain period of time, and when this water supply is started, if the softening agent is put into the input port 22, the water and the finishing agent will meet at the trifurcated tube 19, and will be supplied to the dehydration tank 4, where it will be dehydrated. The fabric softener permeates into the clothing 28 on the side along with water. In this way, "water supply" is done, and then contact T3
By closing, the dewatering motor 9 is energized for a certain period of time and ``dehydration'' is performed.

If the changeover switch □8 is turned on in advance to the A side, the timer 13 will operate continuously regardless of whether the final water supply contact T2 is opened or closed, and a continuous course is selected that does not require the injection of finishing agent. can.

Contact T5 controls the energization of the buzzer 27,
In continuous courses, at the end of the last cycle, and in finishing courses, at the end of the final water supply.
The sound is emitted immediately before the timer 13 stops and at the end of the final cycle. Note that a display lamp may be used instead of the buzzer 27.

As is clear from the above embodiments, according to the present invention, the timer can be appropriately selected to stop before the water supply before the final cycle of dehydration and rinsing, and finishing agent, etc. can be added accurately and easily at a time suitable for dehydration and rinsing, and a good finishing effect can be achieved.
