Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a washing machine for general household use, and particularly to one provided with a second washing tank within the washing tank.

[Conventional technology]

Conventionally, a device in which a second washing tank is provided within the washing tank is disclosed in Japanese Patent Application Laid-Open No. 60-58195 and Japanese Utility Model Publication No. 51-9816.
It was proposed in the Publication No.

[Problem that the invention seeks to solve]

However, these conventional techniques are only proposals based on the principle of providing a second auxiliary tank equipped with a second blade within the washing tank, and have many drawbacks in concrete implementation as shown below. was.

1. With regard to the fixing method and ease of attachment and detachment of the second tank, there is no clear guideline for positioning it in the horizontal direction, and the ease of attachment and detachment is poor. Also, as a series of models, there is a model without a second tank, and the traces of the fixing part remain, so it has no commercial value.

2. When rinsing with water, an overflow port is provided in the middle, but because of this, the effective depth of the second tank is small, and the washing capacity is small.In addition, the mold structure is complicated due to the sliding method when manufacturing the mold. Become.

Furthermore, the amount of water that overflows cannot be visually confirmed, and there is no guideline for the flow rate.

3. If the axes of the first and second blades are not aligned, the rotation will be discontinuous and not only will the specified performance in terms of cloth movement and cleaning performance not be obtained, but also magnetic or fluid In this type of connection, the transmitted torque is relatively small, and there is a large limit to the cleaning action of the second blade.

4. The internal volume of the second tank is relatively smaller than that of the first tank and the capacity when washing the upper and lower parts at the same time. For this reason, the cleaning power in the second premises is limited due to the cleaning power mainly based on the frictional action of the blades, and it is not satisfactory when cleaning stubborn stains on white sports socks or small items such as work gloves. I can't get the desired cleaning performance.

5. The wastewater in the second tank is drained into the first tank, so if you are washing relatively clean items in the first tank and items with a lot of dirt in the second tank, the washing liquid I am dissatisfied with the reuse of the materials.

6. When the second tank was removed, water dripped from the outer wall and wet the floor.

The purpose of the present invention is to eliminate the drawbacks of the conventional technology as described above, and to make it possible to completely wash and rinse items at the same time. To provide a washing machine which has high cleaning performance to cleanly remove even dirt, is highly safe in use, and can be put into practical use immediately.

In particular, the object of the present invention is to provide a highly practical washing machine that can warn of overload and prevent damage by adjusting the holding force of the holding plate for forced washing, which is provided as a means to cleanly remove stubborn stains such as white socks. The point is to provide the following.

[Means for solving problems]

The above purpose is to fix the second tank to the first tank by constructing a separate detachable hanger, forming a pair of U-shaped recesses as overflow ports in the top flange of the second tank, and fixing the second tank to the first tank. A restraining plate that covers the top surface of the tank and is detachable and whose height can be adjusted and fixed in multiple stages is constructed, and the restraining force of this restraining plate is adjusted so that it comes off when overloaded.
The coupling between the upper end of the hollow cylindrical body of the blade and the lower end of the second blade shaft is composed of male and female splines, respectively, and the drainage channel of the second tank is configured to lead to the open external drainage channel of the first tank. ,
This is achieved by configuring a removable water tray on the bottom of the second tank.

〔Example〕

Hereinafter, embodiments of the present invention will be explained with reference to the drawings, taking a two-tank method as an example. In FIG.
A base 2 made of synthetic resin on which this outer frame 1 is placed, and an outer frame 1
A washing tank 3 made of synthetic resin housed inside, a water receiving tank 4 formed integrally with this washing tank 3 and housed in the outer frame 1, a dewatering tank 5 housed inside this water receiving tank 4, and a washing tank 3. A main blade 6 provided at the center of the bottom of the tank 3, a washing motor 7 serving as a drive source for the main blade 6, and a dehydration motor 8 serving as a drive source for the dehydration tank 5.
The washing tank 3 and the water receiving tank 4 are provided above the outer frame 1 by using the upper opening edges thereof. Wash, rinse.

It is equipped with an operation panel 9 that controls various operations such as dehydration and drainage.

A reducer 11 having a driven pulley 10 pivotally supported at its lower end is fixed to the center bottom of the washing tank 3, and the main blade 6 has a hollow cylindrical body 12 projecting upwardly at its center on its output shaft at its upper end. is pivotally supported, and a cap 13 is attached to the upper end of the hollow cylindrical body 12.
is installed.

Further, the driven pulley 10 is connected by a belt 15 to a drive pulley 14 that is pivotally supported above the washing motor 7, so that the rotation of the washing motor 7 is transmitted to the main blade 6 to perform normal washing and rinsing operations. It has become.

On the other hand, above the washing tank 3, as shown in FIG. 3 by coming into contact with hangers 21 which are removably provided with set screws 20 on the lower surface of the flange 18 and the lower surface of the left end of the water receiver cover 19 provided to cover the upper opening of the water receiver tank 4. Thus, the downward direction and rotational direction are fixed. Moreover, on the upper flange 17,
As shown in FIG. 4, U-shaped notches 22 are partially opposed to each other, and a handle 23 used for attaching, detaching, or moving the second tank 16 is pivotally supported.

A bearing 25 for pivotally supporting the second blade 24 is fixed to the center bottom of the second tank 16 by a nut 26, and a bearing 25 is inserted into the cap 13 at the lower end to prevent rotation of the main blade 6. Cup lug 13 and coupling 27 for transmission
The shape of the connecting part of the cap 1 is as shown in FIGS. 6 and 7.
3 and the outer circumferential surface of the coupling 27. The upper end of the spline convex portion of the cap 13 and The lower end of the spline convex portion of the coupling 27 is configured to terminate with a smooth slope.

The number of teeth of this spline is set to the maximum within a range that ensures the torsional strength of the tooth base against the transmitted torque. The connection between the cap 13 and the hollow cylinder 12 is also similar to that described above. Further, on the lower inner circumference of the second tank 16, a large number of protrusions 28 are formed to promote friction during washing.

Next, a drainage mechanism section 29 is formed in one section of the second tank 16, and the drainage from the drain port 30 at the bottom is not drained into the washing tank 3 through a connecting hose 31, as shown in FIG. The structure is as follows. Inside the drainage mechanism section 29, there is a drainage valve 32.
Interposed spring 33. An operating lever 34 is provided, and by moving the operating lever 34 up and down, drainage can be switched, and these are covered by a drainage filter 35.

Next, a plurality of recesses 36 are partially formed on the walls of the drainage filter 35 and the second tank 16, facing each other in the circumferential direction.
A restraining plate 3 having an input port 37 in the center to engage here.
8 is provided. A second tank 1 is provided on the lower surface of the holding plate 38.
6, a large number of protrusions 39 are provided, and on the outer periphery,
Fixing protrusion 4 integrally formed with restraining plate 38 at opposing position
0, and a movable protrusion 41 are provided, one movable protrusion 41
is configured to be movable in the front-back direction by an operating hook 42 and an operating spring 43.

Here, the spring force of the operation spring 43 and the recess 36 provided on the wall surface of the second tank 16 and the fixed protrusion 40 or movable protrusion 41
By adjusting the length of the fitting, the holding plate 38 is designed to come off in the event of overload, in order to prevent an accident in which the holding plate 38 is damaged and scattered if more than a predetermined amount of laundry is put in. has been done.

Furthermore, as shown in FIG. 9, a water receptacle @44 having an upwardly projecting center and an upwardly directed flange on its outer periphery is fixed to the bottom surface of the second tank 16.

With the above configuration, the operation of attaching the second tank 16 and washing it will be explained.

First, hold the handle 23 and set the second tank 16 in the washing tank 3. At this time, the hanger 21 and the upper flange 17 of the second tank 16 are set as a guide for positioning. As a result, the coupling 27 is inserted into the cap 13, and since the rotational resistance of the second blade 24 is extremely small, the coupling 27 is guided by the smooth slopes of both spline protrusions as described above, and the second blade 24 will rotate and engage smoothly. Furthermore, even if the centers of both spline convex portions coincide, they can be smoothly engaged by lightly rotating the second blade 24. Next, water supplied from the water supply outlet 45 provided at the bottom of the operation panel 9 is supplied into the second tank 16 from the notch 22 . Thereafter, by setting the water flow select switch 46 on the operation panel 9 and turning the washing timer 47, the washing action is performed. At this time, the water flow select switch 46 is connected to the main blade 6 and the second
The size and shape of the blades 24, the washing tank 3 and the second tank 16
The optimal water flow can be selected depending on the size, shape, type of items to be washed, etc. Further, since the rotational resistance of the object to be washed differs between the upper and lower parts due to the large number of protrusions 28 provided on the lower inner circumference of the second tank 16, the rotational resistance of the object to be washed is promoted, and uneven washing is reduced. Also, when rinsing with water, water is poured from one side of the notch 22 at the top of the second tank 16, and water overflows from the other side. Therefore, on the water injection side, the backflow of fresh water injected can be prevented and water wastage can be prevented.Also, on the overflow side, overflow water is rectified, so not only can the guideline for adjusting the amount of water injection be clear, but also the guideline for wasting water can be prevented. It will also happen. Furthermore, the notch 22 can also improve the rigidity, design, and commercial value of the upper flange 17. Furthermore, as shown in FIG. 10, the notch 22 also serves as a hair removal lever for gripping the handle 23, thereby improving handling.

Next, stains that cannot be removed by regular washing, such as stubborn stains on white athletic socks, dirt on children's clothing, and work gloves, are generally removed by hand washing, which takes a lot of effort. This is the reality. On the other hand, the holding plate 38 of the present invention is operated by the operating hook 42, one movable protrusion 41 is recessed, the other fixed protrusion 40 is inserted into the recess 36, and the movable protrusion 41 is inserted into the opposing recess 36. Possibly the operating spring 4
The restraining plate 38 is fixed by the elastic force of 3. By setting the clothes in the second tank 16, as shown in FIG. 28, it is continuously subjected to mechanical effects such as friction, bending and stretching, and impact with a certain pressure, and always remains on the surface of the second blade 24. Therefore, the effectiveness of the cleaning action in conventional washing machines is greatly improved. FIG. 12 shows the cleaning effect of the present invention. This also shows the magnitude of the cleaning effect of the present invention. Further, the cleaning power can be further improved by optimally selecting the water flow select switch 46 described above and adjusting the height of the holding plate 38 to the optimum height according to the amount of clothes. When the holding plate 38 is not used, the operating hook 42 is attached to the upper flange 17 of the washing tank 3, as shown in FIG. By using it and hanging it, there is no need to worry about getting the floor wet, and the ease of handling is further improved. In addition, it is safe because it is constructed so that when the user washes more socks than the normal amount specified in the instruction manual, the restraining plate 38 will break and come off before it scatters with a loud noise. Yes, you can use it with confidence.

Furthermore, when the second tank 16 is placed on the floor or the like, the lower end of the coupling 27 is above the bottom surface of the second tank 16, so the stability of the second tank 16 is good, and the coupling 27
Reliability is improved because problems such as damage to the lower end or damage due to excessive external force being applied to the bearing 25 can be prevented.

In addition, the drainage in the second 4'516 is configured so that it is not drained into the washing tank 3 through a separate pipe, so if you want to wash relatively clean items in the washing tank 3 below. Also, since the washing liquid is not contaminated more than necessary, the washing liquid can be reused, and the water saving effect is large. Furthermore, as shown in FIG. 14, the main body drain pipe 45 is connected in the middle, and although the details are not shown, depending on the rotation angle of the cock switching knob 46 on the operation panel 9, the water can be drained only from the washing tank 3 or only the second tank 16. ,
Since it is possible to switch between simultaneous drainage on both sides, there is only one external drainage hose, which improves ease of handling. Furthermore, FIG. 15 shows the drainage from the second tank 16 being guided into the water receiving tank 4. This simplifies the configuration of the exhaust pipe, which can reduce costs.

Furthermore, as shown in FIG. 16, when the second tank 16 is removed and placed on the floor while overflowing water adheres to the outer wall of the second tank 16 during washing or rinsing, the water tray 44 can catch these water droplets. There is no need to worry about getting the floor wet, making it easier to handle. Furthermore, as shown in FIG. 17, by making the water tray 44 separate, it is possible to wash in the lower washing tank 3 and the second tank 16.
Even if the device is removed with water scattered during rinsing at the same time still attached to it, by placing it on a separate water tray 28, the place where it is placed can be prevented from getting wet with water, so that the ease of handling is further improved.

Further, according to the present invention, since the lower washing tank 3 and the upper second tank have completely independent washing functions, the washing
Not only can you rinse each part independently, but you can also wash them top and bottom.
Rinsing can be done simultaneously, and items that are washed two or three times in a row can be processed at the same time, which is a great benefit for housewives who are busy with daily housework and childcare. Further, according to the present invention, when washing only small items such as underwear and handkerchiefs, it is possible to wash them in the relatively small capacity second tank 16 instead of washing them in the large capacity washing tank 3. Not only is the water-saving 9-detergent highly effective, but it can also be used to remove stubborn stains.

Glued can be used in a variety of ways, including containers and washing baskets.

Although the present invention has been described above using a two-tub method washing machine as an example, the same effect can be obtained in a single-hole fully automatic washing machine.

〔Effect of the invention〕

As described above, according to the present invention, the drawbacks of the prior art can be overcome, and the clothes and the blade, which is the main cause of the washing effect, can be effectively brought into contact with each other as many times as possible under a certain pressure. Stubborn stains, which are the biggest worry for housewives who want to wash their clothes every day, can be easily removed with a washing machine, without the hassle of washing by hand.

It is especially safe because it is designed to warn of overload and prevent scattering when using the restraining plate for forced scrubbing to remove stubborn dirt.
