Embodiments of the present invention will be described below with reference to the drawings.

(Embodiment 1) FIG. 1 is a structural diagram of a cleaning apparatus and a bathtub in Embodiment 1 of the present invention, and FIG. 2 is a detailed view of the cleaning apparatus.

The bath 1 is provided with a washing device 2. The cleaning device 2 includes a collection tube 3 for generating a swirl, and a pump (water supply means) for supplying water to an inflow port (injection port) 3a into which a jet flow flows for generating a swirling flow in the collection tube 3.
5, a water supply port (water absorbing portion) 6 of the pump 5, and a control circuit 7 for controlling the drive of the pump 5.

At the suction port of the pump, a trap 8 made of a wire mesh having an aperture of 2 mm is provided to prevent foreign matter from flowing into the pump.

Next, the operation and operation of this embodiment having the above configuration will be described.

First, before starting the apparatus, the bathtub has a diameter of 6 mm.
A polyethylene granule 9 having a specific gravity of 0.98 mm
Ten thousand pieces are put in, and since this granule 9 is slightly lighter than water,
In a stationary state, it floats on the surface. When a switch (not shown) of the apparatus is turned on to start the cleaning apparatus 2, the pump 5 is driven from the control circuit 7. The pump 5 draws the bath water sucked from the water supply port 6 through the inflow port 3a into the collection cylinder 3
Squirted into. The inflow port 3a extends downward in the horizontal direction with respect to the inner wall of the collection cylinder 3 within a range of 10 degrees to 45 degrees.
The water is injected from the inlet 3a at an angle of incidence in the range of 0 to 30 degrees with respect to the tangential direction of the inner wall of the collection tube 2, and the water injected from the inflow port 3a goes downward while turning around the inner wall of the collection tube 3. The swirling flow causes a swirl to occur on the upper opening 3b of the collecting cylinder 3, and the bath water in the upper part of the collecting cylinder 3 is sucked from the opening 3b. It is sucked.

The granules 9 sucked into the collecting cylinder 3 are swirled into the bathtub 1 from the discharge port 4 below the collecting cylinder 3 along a swirling flow. Since the ejected particles 9 are swirling, they are scattered over a wide range and a part of the particles 9 collide with the bathtub wall. At the time of collision, the granular material 9 removes dirt from the bathtub wall surface and performs cleaning. The granules 9 circulate in the bathtub 1, and a part of the granules 9 flowing on the surface of the bath water flow along the waterline of the bath wall, and advance while rubbing dirt on the waterline portion. Thereafter, the liquid is again sucked into the collection tube 3.

(Embodiment 2) FIG. 3 is a detailed view of a cleaning apparatus according to Embodiment 2 of the present invention.

The second embodiment is different from the first embodiment in that a filter tube 10 having a double tube of an outer tube 10a and an inner tube 10b is provided below the collecting tube 3 and the inner tube 10b has a diameter of the granular material 9. It has a number of smaller holes, the filter tube inner tube 10b is connected to the water discharge side of the collection tube 3, and a filter (filtration filter) 11 is provided at the opening between the inner tube 10b and the outer tube 10a. .

The components having the same reference numerals as in the first embodiment have the same structure, and a description thereof will be omitted.

Next, the operation and the operation will be described. The process until the particles are sucked into the collecting cylinder is the same as that of the first embodiment, so that the description is omitted.

In the present embodiment, the granular material 9 is guided to the filtration tube 10 after passing through the collection tube 3. The collection tube 3 and the filtration tube 10 are integrated, and the granules 9 pass inside the filtration tube 10 while turning inside the tube at high speed. Since the granules 9 are circulated in the bathtub 1 and cleaned, some of the peeled dirt is singly used.
Further, a part of the particles adheres to the granules 9 and is sucked into the collection cylinder 3. Due to the swirling flow in the filter tube 10, centrifugal force acts on the dirt, and the size of the dirt is smaller than the size of the hole opened in the filter tube inner tube 10b.

Also, the dirt adhering to the granules 9 is separated from the granules 9 by swirling in the collection tube 3 or the filtration tube 10 and is similarly washed out of the inner tube 10b of the filtration tube 10.
The washed-out dirt is captured by the filter 11 following the filter tube outer tube 10a. Since the particles 9 are larger than the hole opened in the inner tube 10b of the filter cylinder, they cannot pass through the inner tube 10b, but pass through while rotating inside the inner tube 10b, and are discharged to the bathtub 1 again from the discharge port 4.

Further, as shown in FIG.
Since the portion 0b has a shape having a waveform, the granules 9
The impact due to the collision with the inner tube 10b during the turning increases, and the separation of the particles 9 and the dirt is promoted. Although the present invention has a waveform shape, other shapes may be used as long as they have irregularities.

As shown in FIG. 5, a shutter has a pore in a part of the inner tube 10b of the filter cylinder, and a shutter having a size on the outer peripheral portion of the inner tube 10b to cover the pore of the inner tube 10b. 12 is slidably mounted in the direction of the arrow in the figure. Driving motor 1 for shutter 12 serving as opening / closing means
A gear 14 is press-fitted into the rotation shaft 3 and meshes with a toothed portion of a movable plate 15 having a tooth shape. The movable plate 15 moves in the direction of the arrow with the forward and reverse rotation of the motor 13. Is driven. The shutter 12 is the movable plate 1
5 is fixed via a support member 16, that is, can be moved in the direction of the arrow by the rotation of the motor 13.

When the motor 13 is driven by an instruction from a control circuit (not shown) of the motor 13 and the shutter 12 covers the pores of the filter tube inner tube 10b, the washing water circulates only inside the inner tube 10b. Therefore, the water sent from the pump 5 is used only for the circulation of the washing water, so that the granules 9 can be strongly ejected, and the washing effect of the bathtub 1 can be further enhanced. In addition, when the washed dirt is captured by the filter 11 as necessary, the shutter 12 is moved downward by the action of the motor 12, and the dirt is discharged from the pores of the inner tube 10b of the filter cylinder. Filtered by a filter 11.

Further, by enabling the opening and closing of the fine pore portion as required, the flow rate in the inner tube 10b of the filter can be varied, and the ability of circulating particles can be changed.

(Embodiment 3) FIG. 6 is a detailed view of a cleaning apparatus according to Embodiment 3 of the present invention. In the third embodiment, the first embodiment
The difference from (or 2) is that the filter 11 and the pump 5 are connected by piping, and the outer tube 10a of the filtration tube has pores.

The components having the same reference numerals as in the first embodiment have the same structure, and a description thereof will be omitted.

The operation and operation will be described. In the present invention, as in the second embodiment, the dirt collected by the collecting tube 3 is filtered by the inner tube 10b of the filtering tube and passes between the inner tube 10b and the outer tube 10a. As a result, it is sucked by the pump 5 and captured by the filter 11. In addition, a number of holes having a diameter of about 100 μm, which are slightly larger than the dirt of the bath water, are also formed in the outer tube 10a of the filtration tube.
The dirt in the bathtub is also sucked from this part by the suction of the pump 5, and this dirt is also captured by the filter 11 downstream.

As shown in FIG. 7, the outer tube 10a of the filtration tube has pores, and a shutter 12 having a size to cover the pores of the outer tube 10a is slidable in the direction of the arrow in the figure on the outer periphery. Installed. A gear 14 is press-fitted into a rotating shaft of a drive motor 13 of the shutter 12, and the gear 14 meshes with a toothed portion of a movable plate 15 having a toothed shape. The movable plate 15 is driven in the direction of the arrow. The shutter 12 is fixed to this driving plate via a support member 17, that is, can be moved in the direction of the arrow by the rotation of the motor 13. When the motor 13 is driven by an instruction from a control circuit (not shown) of the motor 13 and the shutter 12 covers the fine portion of the outer tube 10a of the filter, the flow from the outside of the filter is stopped. The circulating water is used efficiently for spraying the granules 9, and can further enhance the effect of cleaning the bathtub wall. When the shutter 13 is moved by the drive of the motor 13 as needed, and the pores are opened, dirt inside the bathtub is sucked by the pump 5 to improve the effect of purifying the bathwater. As described above, the motor 13 is driven by an instruction from the control circuit (not shown) of the motor 13 and the shutter 12 enables opening and closing of the fine pores as necessary, so that the bathtub can be cleaned or the bathwater can be purified. Can be used independently or selected.

In each of the above-mentioned embodiments, the general shape of the granules 9 can sufficiently achieve the cleaning effect, but the shape of the granules 9 should be uneven as shown in FIG. Accordingly, the contact portion becomes sharp at the time of collision with the bathtub wall surface, and the cleaning effect is further improved.

Further, if the material of the granules is formed of a substance soluble in water, if it is put into a bathtub when necessary, it will not dissolve naturally after the work, and there is no need to collect it.
Cleaning work is simplified.
