Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention is provided with two washing tanks, and the detergent solution used in one washing tank is used by supplying water to the other washing tank without discarding it. The present invention relates to a two-tank washing machine that attempts to save on expensive detergent.

[Conventional technology]

Currently, many households use washing machines more than once at a time, and for this reason, a washing machine having two adjacent washing tanks is described, for example, in Japanese Utility Model Application Publication No. 55-39097.

The device disclosed in Japanese Utility Model Application Publication No. 55-39097 can use two washing tanks at a time, so it can perform normal washing control that performs washing, rinsing, etc., and fully automatic washing control that automatically performs everything from washing to dehydration. Since each washing process can be done independently, it is possible to shorten the washing work time, but normally, detergent is first added to each washing tank, and then the detergent liquid is drained after one washing process. I wanted to wash it and threw it out of the machine.

If you want to reuse detergent-containing washing water for washing, you have to use only one washing tank for washing, and then take out the washed items by hand and transfer them to the other rotating tank.

In addition, in the one described in the above publication, only separate timers are provided for each of the two washing tanks,
It was designed to only work independently.

Furthermore, it is described in Japanese Utility Model Application Publication No. 54-72874 that water is saved by supplying less dirty rinse liquid from the final cycle to the washing tank in a dehydrating rinse washing machine, but detergent is automatically reused. I had no intention of doing so.

[Problem that the invention seeks to solve]

As mentioned above, with the conventional technology, expensive petroleum-based detergent is discarded outside the washing machine in one washing process, which is not economical.In addition, it is not economical to reuse the washing water containing detergent to make washing easier. , a person has to approach to check when one washing tank has stopped, submerge his/her hand in the tank, take out the laundry that is still dripping with water, and move it to the adjacent second tank.
It took a lot of effort and wasted time.

[Means for solving problems]

An interlocking button that is provided between the two washing tanks and is operated to link the water pump to the other washing tank without discarding the detergent liquid used in one washing tank, and the two washing tanks. and

[Effect]

By operating the interlocking button, one of the washing tanks starts, and when the water enters the drain after the water supply and washing process, the other washing tank starts and the water supply process starts, and the pump is activated, and the detergent solution used in the one washing tank is supplied to the other washing tank for use without being discarded.

〔Example〕

As shown in FIG. 1, the structure of the washing machine of this invention is a two-tank type consisting of a washing tank A1 and a washing tank B2.The washing tank A has a dehydrating basket 3, and is capable of dehydrating the items to be washed. Washing tank A can wash 2.5 kg, the standard water volume of the tank is 35, and washing tank B can wash 2.5 kg.
It is small and can wash 2.2 kg, and the standard water volume of the tank is 31 kg. By operating the dedicated button 5, the washing tank A can automatically perform a continuous process from water supply to washing to rinsing to dehydration in about 43 minutes and 40 seconds. On the other hand, washing tank B automatically performs water supply, washing, and rinsing in about 34 minutes by operating the dedicated button 6, but it does not have a dehydration function, so to dehydrate the items you have already washed them. It is necessary to transfer the water to tank A and dehydrate it for about 5 minutes by operating the dehydration only button 8. It goes without saying that if the amount of laundry to be washed at one time is about 2 kg, it is sufficient to use either tank A or B, and it is no different from a conventional automatic washing machine or a two-tank automatic washing machine.

However, in conventional usage, it is common sense to wash in two times when washing a large amount, or when washing a small amount of items that are extremely dirty or mixed with colored items. The drawback is that it takes about twice as much time to use detergent and detergent. The purpose of this invention is to provide two adjacent washing tanks A and B.
The main feature of this machine is that it washes almost simultaneously, and the detergent solution and water required are sent sequentially from tank A to tank B using its own pump, making them useful twice.

The specific operation of the embodiment will be explained below with reference to FIG.

Assuming that there are approximately 4 kg of items to be washed and that they are to be washed using the washing machine of the present invention, it is desirable to first divide the items to be washed into two groups according to the degree of soiling. Approximately 2 types for lightly soiled and heavily soiled items
Divide it into equal parts and put the lighter one into tank A and the worse one into tank B. Next, put an appropriate amount of detergent only into tank A, and start by operating the AB interlock button 7 shown in Fig. 1. The operation of the washing machine using button 7 is different from the separate operation using dedicated buttons for tanks A and B, and serves to link tanks A and B, and the continuous process for both is shown in Figure 2. Illustrated.

First, when starting with A-1, tank A reaches the specified amount of water within the water supply time of 2 minutes and 40 seconds and washes for 7 minutes. A-4 takes 2 minutes to drain water, but by transferring this detergent solution, which was conventionally flushed away, to tank B with a pump instead of discarding it, water is supplied to tank B. Start washing for minutes. During this time tank A
is dehydrated for 2 minutes in the built-in dehydration basket (A-5),
Furthermore, to clean the inside of your own tank, rinse water (A
-6) After dehydration (A-7), water is supplied and the first rinse is performed (A-9). When time passes and the rinse water in tank A is drained again (A-10), tank B has completed draining to the outside (B-3), and thus water is supplied in synchronization with the drainage in tank A. It is now possible to obtain (B-4). Similarly, tank B
Repeats the following of tank A, but the following two points are noteworthy. One is the drainage of tank A and tank B.
Since it is necessary that the water supplies of the two stations always match, idles (A-15) and (B-7) may be arranged on both sides for time adjustment. Another problem is that although it is normally enough to rinse water twice, in the case of tank B, the water received is already used water from tank A, so it cannot be said to be clean. Therefore, tank B will be rinsed three times, and the water will not be rinsed in tank A, but will be drained immediately after water supply (A-16, A-17) and transferred to tank B. shall be used as such. Thus, tank A started and 43 minutes and 40 seconds later, at the same time when dehydration was completed, 9
Tank B, which started tracking after 40 minutes, also stops after washing has been completed. However, since tank B does not have a dehydration function, after removing the laundry from tank A, transfer it from tank B, manually operate the dehydration only button 8 in FIG. 1, and the process will be completed only after 5 minutes. The difference in capacity between tank A and tank B was made, and the standard water volume for the former was set at 37, and the latter at 31, taking into account the loss of water during the series of operations in the former.

Next, another embodiment will be explained.

B. Switching strength for each tank By adding a washing strength switching function to tanks A and B, it is possible to simultaneously wash different wash strengths depending on the content and degree of the items to be washed.

B Regarding water supply for finishing rinse In the case of linked washing of tanks A and B in this invention, in order to simplify the mechanism, it is assumed that all water supplied to both is transferred to tank B via tank A. At this time, the water required for tank B is:
Even if it is transferred in a stationary state for the third time, tank A
Depending on the degree of contamination of the input materials, it cannot be said that the water is clean. Therefore, for the third rinsing of tank B only, it would be perfectly possible to add a system in which water is supplied directly to tank B from the B side of the water supply valve 10 in FIG. 1 without passing through tank A.

C. Combined use of a dewatering device In this invention, a dehydrating device is installed only in tank A in order to save manufacturing costs, but conversely, if tank B is also equipped with a dehydrating device similar to tank A to save manpower, a second dehydrating device can be installed. The effort of moving from tank B to tank A in the figure and operating the dehydration button is unnecessary, and the dehydration only button 8 and its circuit in Fig. 1 are no longer necessary. That is, by operating only the interlock button 7 for tanks A and B, everything in both tanks is automatically completed.

D. Sharing of electric motors In addition to the case where tanks A and B are used for linked washing, this invention allows tanks A and B to be used as desired, in which each has its own electric motor as shown in Figure 1. However, in order to save manufacturing costs and space inside the housing, it is also possible to use one electric motor to drive tanks A and B. FIG. 3 is an explanatory diagram focusing on the drive structure, omitting the water supply and drainage structure, etc., and shows a state in which tanks A and B are simultaneously operated in conjunction with the rotation of one electric motor 14. . That is, the electric motor 14 located approximately in the center has a coaxial drive shaft with a joint structure penetrating left and right, and the left drive shaft 19 is connected to the tank A1 via the bevel gear 17 at its tip.
It is interlocked with the washing drive bevel gear 15. The drive shaft 20 on the right in one direction is connected to the washing drive bevel gear 1 of the tank B2 via the bevel gear 18 at its tip.
It is linked to 6. Taking the continuous process in Figure 2 as an example, the dehydration in tank A (A-5) and the washing in tank B (B
-2) at the same time, but when only tank A performs rinsing (A-9) and tank B performs drainage (B-3), the operation of B Since this becomes unnecessary, the drive bevel gear moves by the action of the joint structure of the B drive shaft shown in FIG. 3, and the bevel gear for tank B becomes unrotatable as shown in FIG. 4. Similarly, in the next step, tank A will be idle (A-15) and only tank B will be idle (B-15).
When carrying out step 9), it is sufficient to operate in the completely opposite manner as described above, and by removing the joint of the drive shaft 19 for A and letting it idle, tank A becomes inoperable for washing (or dewatering). In addition, when only tank A or tank B is used individually, it goes without saying that the purpose can be achieved by idling the other drive shaft from the beginning.

E. Upper and lower two-tank system This invention has two tanks arranged side by side to transfer water using a pump.
Alternatively, to prevent pump troubles in cold regions, a two-tank system without a pump may be considered. An example is shown in FIG. 5, where tank A1 having dehydration basket 3 is located directly above tank B2,
Water is supplied from tank B to tank B using a three-way drain valve 21.
It can be easily reached by falling naturally through.
When only tank A is used, it is completely optional whether to switch to the same three-way tank and drain water directly to the outside, or to drain water via tank B. However, in order to wash according to this specification, it is necessary to provide an inlet for the items to be washed in both tanks A and B on the front.As an example, in Fig. The illustration is based on the premise.

〔Effect of the invention〕

The advantage of this invention is that it saves (i) detergent, (ii) labor, and (iii) time.

(i) Detergent is the most expensive consumable item required for washing, and is said to be the reason why housewives dislike automatic washing machines because it is uneconomical to throw it away every time. In order to make up for this shortcoming even a little, automatic washing machines are equipped with a "wash only" option.
However, in reality, it is a hassle to dip your hands in the detergent solution once you have washed it and take out the items you want to wash, as well as a place where the removed detergent solution drips. Two points remained unresolved and the machine was considered inferior to the current two-tank washing machine with a dehydrator, but this invention was able to solve these problems.

(ii) Regarding labor savings, this invention uses a pump to transfer the detergent solution from tank A to tank B without touching the items to be washed, making it possible to reuse it immediately. It is.

(iii) As is clear from Figure 2, the time required is that tank A, which corresponds to a conventional automatic washing machine, is idle for only 1 minute and 20 seconds (A-15), and the dewatering time for tank B is 5 minutes.
It can be said that by adding up the amount of water (B-16), it is possible to wash and dehydrate approximately twice as much water.
