Abstract

PURPOSE:To prevent a reduction in rinsing performance by providing a means for giving priority to water injection rinsing step or water feeding step, giving priority to the water injection rinsing step on either one tank side, temporarily stopping the operation of the step on the other tank side, and bringing this tank side into waiting water until the priority step is finished. CONSTITUTION:A means for giving priority to only the water injection rinsing step in either of both tanks 1, 2 and bringing the other into waiting state, when confliction of water rinsing step is caused between the both tanks, is provided. When the step of each tank proceeds, and confliction of the step marked by occurs, the water injection rinsing in one tank is preferentially conducted, and the water feed on the other tank side is temporarily stopped into waiting state until this water injection rinsing is finished. The water injection rinsing step proceeds with ensuring the general water injection quantity, and it is automatically restarted so that the respective step in each tank can be conducted in parallel together with the termination of the priority. Namely, the causes such that soap sediments are left on a washed material after washing, causing inflammation of the skin, and thread wastes and cotton wastes are not sufficiently removed from the washed material can be solved.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a fully automatic washing tank and a non-fully automatic washing tank that are installed side by side, and a water injection rinsing process for one of the layers to be washed;
The present invention relates to an operation control device for a washing machine that prevents deterioration of rinsing performance when water supply or water injection rinsing process of the other washing tank conflicts.

[Conventional technology]

Fully automatic washing tanks, i.e., fully automatic washing tanks that automatically perform all processes of water supply, washing, drainage, rinsing, and dehydration (hereinafter referred to as fully automatic washing tanks), and non-fully automatic washing tanks, i.e., excluding the dewatering process. For example, Japanese Patent Publication No. 63-66232 describes a washing machine in which a non-fully automatic washing tank (hereinafter referred to as a non-fully automatic tank) that performs the processes of supplying water, washing, draining water and rinsing, either independently or automatically, is installed in parallel. proposed earlier.

However, since the washing machine adopting the above configuration has a fully automatic tank and a non-fully automatic tank installed side by side, it is possible to wash colored items and white items separately and at the same time. You can wash the items at the same time or wash them first in the non-automatic tank side.
After washing, the items to be washed are transferred to the fully automatic tank for rinsing and dehydration. 1. During this time, the washing liquid and rinsing liquid are reused in the non-automatic tank for the next wash, so-called forward washing. It has the advantage of being able to

[Problem to be solved by the invention]

However, as mentioned above, in the conventionally proposed washing machine in which a fully automatic tank and a non-fully automatic tank are installed side by side,
Water injection rinsing and water supply, v) do not recognize the problems when water injection rinsing is operated simultaneously in each tank. For this reason, for example, if water injection rinsing is performed on the fully automatic tank side and water is supplied on the non-automatic tank side, in regions b) where water pressure is low, the amount of water required for water injection rinsing will be smaller, and the specified rinsing performance will be reduced. As a result, soap scum remains on the items to be washed after washing, which not only causes a strong odor and causes skin irritation, but also makes sure that lint and cotton waste are not sufficiently removed from the items to be washed. It can also be the reason why they don't leave.

An object of the present invention is to provide a washing machine with a fully automatic tank and a non-fully automatic tank installed side by side, in which case the water injection rinsing process of one of the tanks conflicts with the water supply or water injection rinsing process of the other tank. By preventing deterioration in performance, soap scum may remain on items to be washed after washing, resulting in too strong a smell or causing dermatitis, and also prevent lint and cotton waste from being sufficiently removed from items to be washed. It is an object of the present invention to provide an operation control device for this type of washing machine, which can solve the causes such as the lack of the washing machine all at once.

[Means to solve the problem]

The above purpose is to solve the problem when, in a washing machine in which a fully automatic tank and a non-fully automatic tank are installed side by side, the water injection rinsing process in the fully automatic tank side conflicts with the water supply process in the non-fully automatic tank side, or, contrary to the above, If the water injection rinsing process on the non-fully automatic tank side conflicts with the water supply process on the fully automatic tank side, or furthermore, if the water injection rinsing process on the fully automatic tank side and the non-fully automatic tank side conflict,
In the former two cases, priority is given to the water injection rinsing process or water supply process; in the latter case, priority is given to the water injection rinsing process in one of the tanks, and the process in the other tank is temporarily operated. This can be achieved by providing means for stopping the process and placing it in a standby state until the prioritized process is completed.

[Effect]

According to the present invention including the control means, in a washing machine in which a fully automatic tank and a non-fully automatic tank are installed side by side, a water injection rinsing process for one of the tanks and a water supply or water injection rinsing process for the other tank are performed. In any case where there is conflict with the process, the water injection rinsing process proceeds while ensuring the normal amount of water injection. It is possible to solve all of the causes of soap scum remaining on items being washed, which can cause strong odors, cause dermatitis, and even prevent lint and cotton scum from being sufficiently removed from items being washed.

A bearing 17 is fixed to the bottom of the non-fully automatic tank 2 installed in parallel with the fully automatic tank 1, and a pulsator (2) 18 is pivotally supported on the bearing 17. Further, a driven pulley (2) 19 is pivotally supported below the bearing l7, and this driven pulley (2) 19 is
It is connected via a belt (2) 22 to a drive pulley (2) 21 that is pivotally supported above a motor (2) 20 supported on a base 3 in a vibration-proof manner, and is driven during washing and rinsing. Furthermore, a water overflow port 23 is provided at a part of the corner of the non-fully automatic tank 2, and the water overflow port 23 performs overflow during water injection and rinsing. Although not shown, an overflow port for water injection and rinsing is also provided on the fully automatic tank 1 side.

On the base 3, there is also an internal drain hose (1) 25, which is installed at the bottom of the outer tank 9 of the fully automatic tank 1 and is connected to a drain valve (1) 24 that opens and closes the valve electrically. A Y-shaped pipe 28 is fixed that joins the two hoses together with an internal drainage hose (2) 27 connected to a drain valve (2) 26 provided at the bottom of the non-fully automatic tank 2. For,
A drain hose 29 outside the machine is connected to drain water to the outside of the machine.

On the other hand, a water supply electromagnetic valve 30 is provided on the operation panel 5, and below the water supply solenoid valve 30, water supply can be turned on and off independently for the fully automatic tank 1 side and the non-fully automatic tank 2 side. , solenoid valve (1) 31 and solenoid valve (2) 3
2 is provided.

FIG. 3 shows an operating section 33 controlled by a microcomputer. That is, in the case of this example,
The microcomputer is programmed to control the water supply to the other tank if the water supply process as shown in the flowchart in Fig. 6 conflicts with the water supply process in the other tank while water injection rinsing is being performed in the fully automatic tank 1 or the non-fully automatic tank 2 side. temporarily stops operation and waits until the water injection rinsing is completed. Furthermore, if the water injection rinsing process in both tanks 1 and 2 conflicts, only the water injection rinsing process in either tank will take priority. , as before, is programmed in advance to put the others in a standby state. Here, the operation of the washing machine having the above configuration will be explained.

First, when a cloth is placed in the fully automatic tank 1 and the operation is started, the operation proceeds through the steps shown in Fig. 4 (in the 4th @, the parts marked 0 are steps related to the present invention). be). However, as mentioned above, the washing machine to which the present invention is applied has the fully automatic tank 1 and the non-fully automatic tank 2 installed side by side, so it is difficult to wash colored items and white items separately. Simultaneous washing that allows you to wash the same items, and washing items in a non-fully automatic tank 2
The washed items are first washed on the side, and the washed items are transferred to the fully automatic tank 1 side for rinsing and dehydration. During this time, the non-fully automatic tank 2
It has the advantage of being able to reuse the washing and rinsing liquid for the next wash.

By the way, this type of washing machine, which has been proposed in the past and has a fully automatic tank and a non-fully automatic tank installed side by side, does not work when water injection rinsing and water supply or water injection plowing are operated at the same time in each tank, as mentioned above. are not aware of the problems. For this reason, 5. For example, if water injection rinsing is performed on the fully automatic tank side and water is supplied on the non-automatic tank side, in areas with low water pressure, the amount of water required for water injection rinsing will be smaller, ensuring the specified rinsing performance. As a result, soap scum remains on the items to be washed after washing, which not only causes a strong odor and causes skin irritation, but also prevents lint and cotton waste from being sufficiently removed from the items to be washed. It may also be the reason why there is no such thing.

On the other hand, in this embodiment, when water injection rinsing is performed in the fully automatic tank 1 or the non-fully automatic tank 2 side, if the water supply process in another tank conflicts as shown in the flowchart of FIG. The water supply to the tank will be temporarily stopped and the water supply will be on standby until the water injection rinse is completed. Furthermore, if the water injection rinsing process conflicts with both tanks 1 and 2, the water injection rinsing process will only be performed in one of the tanks. Since there is a means to give priority to one tank and put the others in a standby state as described above, as shown in FIG. Priority is given to the water injection rinsing, and until this water injection rinsing is completed, the water supply in other tanks is temporarily stopped and the water supply is in a standby state, and the water injection rinsing process proceeds while ensuring the normal water injection amount. However, with the completion of the above-mentioned priority process,
According to the present invention, the process of each tank is automatically restarted so that each process is performed in parallel.
As with conventionally proposed washing machines that have a fully automatic tank and a non-fully automatic tank installed side by side, the water injection rinsing process in one of the tanks competes with the water supply or water injection rinsing process in the other tank, resulting in poor rinsing performance. There are problems when soap scum remains on the items to be washed after washing, and the odor is too strong and causes skin irritation.Furthermore, lint and cotton waste may not be sufficiently removed from the items to be washed. This is where you can solve all the reasons why you are not able to do it all at once.

FIG. 8 is a plan view showing a modification of the operation panel 5 shown in FIG. 3, and as shown in FIG. By attaching display standby lamps 34 and 35, it is possible to make the worker visually aware of the progress of the washing currently being carried out. The time period during which the water injection rinsing process is given priority and the water supply process on the non-fully automatic tank 2 side is temporarily stopped and is in a standby state is set in advance from the start of water injection on the upper side of the fully automatic tank where water injection rinsing is performed. If the water pressure is 5, which corresponds to the amount of water supplied at the place of use, it is possible to perform the M rotation corresponding to the amount of water supplied at the place of use.In this case, as shown in FIG. It's okay.

FIG. 7 is a flowchart showing specific content different from FIG. 6 executed by the device of the present invention, and in the same figure, after the start of water injection rinsing, the water level on the fully automatic tank side, where the water injection rinsing process is performed with priority. With a sensor for detecting fluctuations,
This system monitors the height of the water level during the water injection rinsing process and controls the priority of the water injection rinsing process on the fully automatic tank side and the temporary standby of the water supply process on the non-fully automatic tank side. be.

According to Fig. 7, real-time processing according to the amount of water being supplied is not possible even if the tap water pressure fluctuates mid-way, or even if water supply (or water supply rinsing) is simultaneously executed in another tank after the start of water supply rinsing. This makes it possible to achieve satisfactory results in terms of stabilization of rinsing performance, water saving effect, and further shortening of washing time.

〔Effect of the invention〕

The present invention is as described above, and the present invention provides a washing machine in which a fully automatic tank and a non-fully automatic tank are installed side by side, in which the water injection rinsing process in the fully automatic tank side and the water supply process in the non-fully automatic tank side compete with each other. Or, contrary to the above, if the water injection rinsing process on the non-fully automatic tank side conflicts with the water supply process on the fully automatic tank side, or furthermore, the water injection rinsing process conflicts on the fully automatic tank side and the non-fully automatic tank side. In the case of the former two, priority is given to the water injection rinsing process or water supply process, and in the latter case, priority is given to the water injection rinsing process in one of the tanks, and the process in the other tank is temporarily suspended. According to the present invention, a fully automatic tank and a non-fully automatic tank can be installed side by side. Like the washing machine related to the conventional proposal,
There is a problem when the water injection rinsing process in one of the tanks competes with the water supply or water injection rinsing process in the other tank, resulting in a decrease in rinsing performance. You can solve all the causes of strong odors, skin irritation, and not being able to remove lint and cotton lint from the items you wash all at once.
