Description

[Detailed description of the invention] This invention relates to a water washing device that has a water tank with a flat inner surface, such as a sink, a washstand, or a water tank, and adds new functions to the water tank without impairing its original functions. For example, this is an additional feature that allows food to be mechanically washed in the water tank.

Generally, a water washing device, such as a water tank in a sink, has a flat inner surface and is used to store dirty dishes and the like and to wash dirty food and the like.

It is generally recognized that cleaning is done by hand, and this is actually the case.

However, the water tank has the function of storing water and preventing water from splashing outside during washing, so if a mechanical rotating shaft etc. is installed, the tableware etc. Its functionality will be dramatically improved, as cleaning can be done mechanically and the water tank can also be used as a dishwasher.

However, if a rotating shaft or the like is provided protruding from the water tank, the image of the water tank as a dishwasher becomes stronger than that of a sink, giving a strange feeling to the user.

Furthermore, in actual use, if the rotating shaft protrudes from the inner surface of the water tank, it becomes a hindrance, making it difficult to perform various operations smoothly.

In other words, there is a concern that it not only damages the image of the sink, but also impairs the original function of the aquarium.

Among these problems, the problem that the rotation shaft gets in the way can be solved by providing a plate above the rotation shaft to cover the rotation shaft, but in this case, the rotation shaft covered by the plate The depth of the aquarium becomes shallower due to the protrusion of the shaft, making it less convenient to use.

The presence of the plate makes the user think that there is something strange at the bottom of the water tank, and it seems that the user cannot get rid of the strange feeling about the sink.

In addition, the biggest problem is that the rotating shaft protrudes into the water tank, so it cannot be applied to ready-made sinks. This results in the necessity of producing two types of products, one without such a product (because the user may not need such a product), and this poses problems in process control, cost, etc.

Furthermore, since the rotating shaft protrudes, new problems arise, such as the possibility of water getting wet.

Therefore, a solution as shown in FIG. 7 has been proposed as a conventional solution to the above-mentioned problems.

That is, in this proposal, a driving magnet 30 rotated by a motor 29 is provided on the back surface of the bottom of the water tank 28 with a gap T between the drive magnet 30 and the bottom surface of the water tank 28 opposite to the drive magnet 30.
A rotary body 31 made of a magnetic material is disposed within the water tank 28 with a gap T between it and the bottom surface of the water tank 28, and the rotary body 31 is rotated by driving the drive magnet 30.

However, since the rotating body 31 is configured to be suspended in the air via the pivot shaft 32 at its center, the pivot shaft 32
Due to manufacturing variations in the mounting method, the rotating body 31 may swing up and down, causing a portion of the rotating body 31 to collide with the bottom surface of the water tank 28, and the rotation may not be smooth.

Also, the leg portions 33 of the support frame 33 that support and fix the rotating body 31
A is provided with a suction cup 34 for fixing, so the rotating body 3
The removal force of 1 is greater than the sum of the attraction force between the rotating body 31 and the drive magnet 30 and the attraction force of the suction cup 34, which makes it difficult to remove the rotation body 31, and this suction cup 34 is difficult to remove. During this process, or due to aging due to being attacked by detergents etc., the suction of the suction cup 34 becomes weak and the rotating body 31 tends, and a part of the rotating body 8 collides with the bottom of the tank, making it difficult to rotate smoothly. There was fear.

On the other hand, since the drive magnet 30 is configured to be held horizontally via the rotating shaft 35 at its center, the rotating shaft 35 and the driving magnet 3
0, the drive magnet 30 rotates vertically due to manufacturing variations, and a part of the drive magnet 30 collides with the storage frame 36, which deforms and rotates smoothly. There was a problem that it wouldn't work.

The present invention solves the above-mentioned problems, and an embodiment of the invention will be explained below by applying it to a sink.

In the figure, 1 is a sink cabinet, 2 is a top plate covered on top of the cabinet, and has small and large water tanks 3 and 4.

Reference numeral 5 denotes a resin box provided in the cabinet 1 below the water tanks 3 and 4, and is opened and closed by a door 6.

The inner surfaces of the large and small water tanks 3 and 4 are flat so that dishes and the like can be stored therein like a conventional sink, and the dishes and the like can be washed by hand.

In such a sink, the top plate 2 including the large and small water tanks 3 and 4 is made of a non-magnetic stainless steel plate or the like.

A donut-shaped magnet 7 with alternating north and south poles is placed on the bottom of the small aquarium 4, and the magnet 7 is rotated on the back of the tank by an electric motor 8 installed at a suitable location inside the cabinet. It looks like this.

That is, 9 is a magnet holder made of a magnetic material such as iron, 10 is a pulley to which the magnet 7 is fixed integrally through the magnet holder 9, and the rotating shaft 11 is an arm 13 projecting from the motor mounting plate 12. It is rotatably supported via a bearing 14.

A belt 17 from a drive pulley 16 attached to the drive shaft 15 of the electric motor 8 is stretched around the outer periphery of the pulley 10, and the rotation of the electric motor 8 causes the magnet 7 to move onto the arm 1.
It rotates around a rotating shaft 11 supported by 3.

Therefore, according to this sink, a brush rotating body 20 having a magnet 19 similar to the magnet described above is prepared, and this brush rotating body 20 is installed on the inner bottom surface of the water tank facing the driving magnet 7 on the back surface of the water tank. If the electric motor 8 is rotated, this rotating body 20 will rotate.

That is, as shown in FIG. 6, the rotating body 20 installed on the inner bottom surface of the aquarium is placed in the N direction of the rotating body side magnet 19.

Adsorption force a generated between the S pole and the S and N poles of the drive side magnet 7
When the drive side magnet 7 rotates, the rotating body side magnet 19 is attracted by the attraction force a.
will also start rotating.

Therefore, by pressing a bowl or the like against the brush 20a of the rotary body 20, a bowl or the like can be mechanically cleaned. By installing it, it can function as a dishwasher.

If the rotary body 20 is removed from the water tank 4, it can be used as a normal sink.In this case, the inner surface of the water tank 4 remains flat, making it easy to clean by hand and store dishes etc. can be done.

Of course, since there is no rotating shaft etc. protruding from the water tank 4, there is no fear of water leakage, and since there is no plate covering the rotating shaft etc., the user will not feel any discomfort.

Furthermore, in this sink, the rotary body 20 is connected to the drive side magnet 7 only by magnetic attraction, so when a large torque is applied to the rotor 20, only the drive side magnet 7 rotates, and the electric motor 8 No overload is applied to the rotating body 20, and removal of the rotating body 20 is relatively easy.

Furthermore, the above-mentioned cleaning function can be added simply by placing magnetic rotation means consisting of the drive side magnet 7, pulley 10, electric motor 8, etc. that drives the rotating body 20 on the bottom back surface of the water tank 4, so it can be applied to ready-made products as is. can do.

Moreover, even when producing a new product, it is sufficient to manufacture one without the above-mentioned magnetic rotation means and attach it as necessary, making process control etc. easier.

In this case, in this embodiment, each part of the magnetic rotation means is attached to the motor mounting plate 12 to form a unit, so the assembly is easy. Attach by welding to.

As a result, the magnetic rotating means is fixedly held within the cabinet.

In this embodiment, the motor mounting plate 12 of the magnetic rotation means is made of a magnetic material such as iron, and its upper end is aligned with the back surface of the back guard 2a of the top plate 2, and the back surface portion of this back guard is attracted by a magnet. It should be made to face.

The motor mounting plate 12 forms the magnet attracting surface.
A reed switch 22 for controlling the operation of the electric motor 8 is attached to a part of the upper end, and a pattern 23 is provided on the surface of the back guard facing the switch part.

Therefore, according to this embodiment, if the switch magnet 24 is attracted to the magnet attraction surface and the switch magnet 24 is attracted to the patterned portion 23, the electric motor 8 can be rotated, which improves ease of use. It can be a good thing.

Further, the magnet 7 driven by the electric motor 8 and the rotating body 20 driven by the magnet 7 are equipped with rollers 25 and 26 that contact the aquarium wall, and the magnet 7 and the rotating body 20 are rotated in the vertical direction due to manufacturing variations. Even if vibration occurs, the magnets 7 and 19 are prevented from coming into contact with the aquarium wall, and since the contact members with the aquarium wall are rollers 25 and 26, the rotation of the rotating body 20 and the magnet 7 is smooth, and vibration noise etc. The noise generation will be reduced.

Then, the rotating body 20 protrudes the shaft 27 and the brush 20
A is removable so that attachments other than brushes can be attached, making it useful not only for washing dishes but also for scrubbing rice,
It is also possible to do laundry etc.

In each of the above embodiments, the magnetic rotation means is provided on the bottom of the small water tank, but it may also be provided on the back surface of the circumferential side or for size measurement. It may also be provided in the water tank of the washstand or the bathtub, and the same effects as in the embodiments described above can be expected.

In this way, according to the present invention, new functions such as dishwashing can be added without damaging the original functions and image of the water tank, expanding the uses of the water washing device and greatly improving its economic efficiency. At the same time, a rotation auxiliary member such as a roller that contacts the aquarium wall is provided not only on the outer circumference of the magnet of the rotating body but also on the outer circumference of the drive side magnet, so a gap between the aquarium wall and the aquarium wall is always maintained. The magnet will not collide with the aquarium wall, and its rotation will be smooth.
In addition, since the rotating body can only be removed by attracting the magnets together,
It has great practical value as it is relatively easy to perform and easy to use.
