Abstract

To simply remove floating matter on a water surface of a bathtub without the need for securement of a power source and waterproof security.SOLUTION: A floating matter removal tool includes a container 10 with an upper surface opened, and filters the water passing a circulation hole by installing a filter part 20 in the circulation hole 11 penetrating through the lower surface of the container. Also, a buoyant part 12 is provided for generating buoyancy to make the upper edge of the container protrude up from the water surface of the bathtub around the container. In this way, the water in the vicinity of the water surface of the bathtub is taken in the container along with the floating matter from an outer edge of the upper edge of the container, by manually sinking the container into the water of the bathtub. When the hand is separated, the container floats up and a water level difference is caused between the water surface in the container and the water surface of the bathtub. The water in the container flows out of the circulation hole and is filtered in the filter part so as to eliminate the water level difference, and therefore the floating matter on the bathtub water surface can simply be removed without the need for the securement of the power source and waterproof security.SELECTED DRAWING: Figure 2

TECHNICAL FIELD The present invention relates to a suspended matter removing tool for removing suspended matter floating on the water surface of a bathtub.

When taking a bath, it feels uncomfortable if dust such as hair or dirt floats on the water surface of the bathtub. Therefore, a technique for removing such suspended matter has been proposed. For example, in the bath descaling device described in Patent Document 1, while floating on the water surface of the bathtub, the water near the water surface is sucked together with the suspended matter by driving the motor, and the suspended matter is removed by filtering with a filter. It has become.

However, in the technique described in Patent Document 1, it is necessary to secure a power source such as a battery in order to drive the motor, and it is necessary to ensure waterproofness so that the motor and the power source do not get wet with water. was there.

The present invention has been made in response to the above-mentioned problems of the conventional technique, and can easily remove suspended matter on the water surface of a bath without requiring securing of a power source or guaranteeing waterproofness. The purpose is to provide possible technology.

In order to solve the above-mentioned subject, the floating substance removal tool of the present invention adopted the following composition. That is,
In the floating material removal tool that removes floating material floating on the water surface of the bathtub,
A container with an open top,
A filter portion that is provided in a circulation hole that penetrates the lower surface of the container and filters water that passes through the circulation hole,
And a buoyancy portion that is provided around the container and that generates a buoyancy force that causes the upper end of the container to project above the water surface of the bathtub.

In such a floating material removing tool of the present invention, the user manually submerges the water in the vicinity of the water surface of the bath from the upper outer edge of the container into the container together with the floating material, so that the user can hold the hand. When separated, it floats up due to the buoyancy of the buoyancy unit, causing a water level difference between the water surface in the container and the water surface of the bathtub. Then, in order to eliminate this difference in water level, the water in the container flows out from the circulation holes on the lower surface and is filtered by the filter section. Therefore, it is possible to easily remove the suspended matter floating on the water surface of the bathtub without needing to secure a power source or ensure waterproofness.

In the above-described suspended matter removing tool of the present invention, the movable member provided in the container so as to be movable up and down is provided, and when the movable member is pressed from above and moves downward, the filter member is covered. The flow of water from below to above may be suppressed, and when the pressing is released, the movable member may return to the above by receiving a restoring force.

With this configuration, when the user presses the movable member when the container is submerged in the water of the bathtub, the movable member moved downward covers the circulation hole, so that water from the circulation hole opened on the lower surface of the container is covered. Since the inflow of water is suppressed, it becomes possible to increase the inflow amount of water from the outer edge of the upper end of the container and efficiently take the suspended matter on the water surface of the bath into the container.

Further, in the above-mentioned suspended matter removing tool of the present invention, the restoring force for returning the movable member to the upper side may be buoyancy for floating in the water in the container.

By using the buoyancy that floats in the water inside the container when the pressure is released as a restoring force that returns the movable member to the upper side, you can easily obtain the restoring force without the need for a separate member such as a spring. You can

Further, the movable member in the above-mentioned suspended matter removing tool of the present invention is a box-shaped body whose upper surface is closed and whose lower surface is opened, and which floats in the water in the container by the buoyancy of the air stored inside. Good.

In such a floating material removing tool of the present invention, floating material diffused in water by the force of water flowing from the outer edge of the upper end of the container passes through the lower end of the box-shaped body from between the container and the box-shaped body together with water. And flows into the inside of the box-like body, and is filtered by the filter portion of the flow hole. The suspended matter that has once flowed inside the box-shaped body is blocked by the side surface of the box-shaped body even if it floats on the water surface inside the container when the outflow of water from the circulation hole is stopped, and the outside of the box-shaped body is blocked. Since it is difficult to return to, the suspended matter can be kept inside the box. As a result, even if the operation of sinking the floating substance removing tool is repeated, it is possible to suppress the floating substances collected in the container (inside the box-shaped body) from returning from the upper outer edge of the container to the water surface of the bath.

Further, in the above-mentioned suspended matter removing device of the present invention, the lower end of the isolation wall is fixed to the container, and is provided with an isolation wall that positions the flow hole inside and separates the inside of the container from the outside. It may be located below the water surface in the container while being separated from the lower surface of the container and in a state where the water level in the container matches the water level in the bathtub.

In such a floating material removing tool of the present invention, once the floating material diffused in the water with the force of water flowing from the upper outer edge of the container passes through the lower end of the isolation wall and once flows inside the isolation wall, from the flow hole. Even if the outflow of water stops and the floating material floats up to the surface of the water inside the container, it is difficult for the floating material to return to the outside of the separating wall because it is blocked by the partition wall, so keep the floating material inside the partition wall. You can As a result, even if the operation of sinking the floating substance removing tool is repeated, it is possible to prevent the floating substances collected in the container (inside the isolation wall) from returning from the upper outer edge of the container to the water surface of the bath.

In the above-mentioned suspended matter removing tool of the present invention, the upper end of the standing wall is provided inside the box-shaped body or the isolation wall by providing the standing wall that surrounds the circulation hole and stands up from the lower surface of the container. May be positioned above the lower end of the box-like body that has returned upward due to the restoring force, or above the lower end of the isolation wall.

In this way, the water that flows from the outer edge of the upper edge of the container between the container and the box-shaped body (or the isolation wall) and diffuses suspended solids passes through the lower end of the box-shaped body (or the isolation wall), and rises further. It flows over the upper end of the installation wall to the inside of the standing wall, and is filtered by the filter portion when flowing out from the circulation hole. Then, when the outflow of water from the circulation hole is stopped, the movement of water from the inside of the standing wall to the outside is blocked by the standing wall, so that the suspended matter once flowing inside the standing wall is suspended by the standing wall. It is difficult to return to the outside of the container, and it is possible to further suppress the floating substances from returning between the container and the box-shaped body (or the isolation wall).

FIG. 1 is a perspective view showing a disassembled state of the suspended matter removing tool 1 of the first embodiment. As shown in the figure, the suspended matter removing tool 1 of the first embodiment includes a round trough-shaped container 10 having an open upper surface, and the container 10 has a circular through hole 11 penetrating through the center of the lower surface. Is provided. Then, the filter portion 20 is detachably installed in the circulation hole 11.

The filter portion 20 includes an upper sieve 21 having a disc-shaped large mesh and a lower sieve 23 having a circular outer frame having a larger outer diameter than the upper sieve 21 and having a large mesh formed on the lower surface. A circular fine mesh 22 is sandwiched therebetween. The upper sieve 21 has a plurality of outwardly facing grooves 21a formed at equal intervals (three in the illustrated example). When the upper sieve 21 is fitted into the circulation hole 11 of the container 10 and rotated, the inner periphery of the circulation hole 11 is formed. A plurality of inward projecting ridges 11a formed at equal intervals are fitted into the groove 21a and fixed.

The lower screen 23 has a plurality of (three in the illustrated example) engagement holes 23a formed in the outer frame at equal intervals, and a plurality of engaging holes formed outwardly from the outer periphery of the upper screen 21 at equal intervals. The mating claw 21b is fixed by engaging the engaging hole 23a. The mesh 22 sandwiched between the upper sieve 21 and the lower sieve 23 may have a mesh number of 50 to 100, for example.

Further, a ring-shaped air chamber 12 is provided on the outer periphery of the container 10 with its lower surface opened. The air chamber 12 is divided into a plurality of partitions by providing a plurality of partitions 12a (8 in the example shown in the drawing) that are provided upright in the radial direction at equal intervals. The air chamber 12 of the first embodiment corresponds to the "buoyancy portion" of the present invention.

FIG. 2 is an explanatory view showing an operation of removing the floating material floating on the water surface of the bathtub by using the floating material removing tool 1 of the first embodiment. In the figure, a cross section of the suspended matter removing tool 1 taken along a vertical plane passing through the center of the flow hole 11 of the container 10 is shown. In addition, the alternate long and short dash line in the figure represents the water surface, and the rhombus and the long quadrangle in the figure schematically represent floating substances such as dirt and hair floating on the water surface of the bathtub.

First, as shown in FIG. 2( a ), when the floating substance removing tool 1 is released to the water surface of a bathtub containing hot and cold water, the lower surface of the air chamber 12 provided on the outer periphery of the container 10 is blocked by the water surface of the bathtub. By floating on the water surface of the bathtub by the buoyancy of the air stored in the air chamber 12, the upper end of the container 10 projects above the water surface of the bathtub. As described above, the air chamber 12 is divided into a plurality of partitions 12a, and the deviation of the air in the air chamber 12 is suppressed. Therefore, the posture of the suspended matter removing tool 1 floating on the water surface of the bathtub is stabilized. Can be made. Further, in a state in which the suspended matter removing tool 1 is floated on the water surface of the bathtub, the water in the bathtub penetrates into the container 10 through the filter portion 20 of the circulation hole 11 opened on the lower surface of the container 10, and And the water level in the bathtub are the same.

Next, the user manually submerges the suspended matter removing tool 1 in the water of the bathtub against the buoyancy of the air in the air chamber 12, and as shown in FIG. When immersed below the water surface, the water near the water surface of the bathtub flows into the container 10 from the outer edge of the upper end of the container 10 together with the suspended matter. At this time, although the water in the bathtub flows into the container 10 through the filter portion 20 from the circulation hole 11 on the lower surface of the container 10, the filter portion 20 has a resistance due to the fine mesh 22, so that from the outer edge of the upper end of the container 10. Inflow of water is prioritized. Further, when water flows in from the outer edge of the upper end of the container 10, the suspended matter is diffused into the water by being stirred by the force of flowing in.

After the water is taken into the container 10 in this way, when the user releases the floating substance removing tool 1, the floating substance removing tool 1 floats on the water surface of the bathtub due to the buoyancy of the air in the air chamber 12, and FIG. As shown in, the water level inside the container 10 becomes higher than the water level of the bathtub, and a water level difference occurs. The water in the container 10 flows out from the circulation hole 11 on the lower surface of the container 10 and returns to the bathtub so as to eliminate this difference in water level. At that time, the water flowing out from the flow holes 11 is filtered by the filter section 20 to remove the suspended matter.

When the water level difference between the water surface in the container 10 and the water surface in the bathtub disappears, the water in the container 10 stops flowing out and returns to the state of FIG. By submerging and repeating the operations shown in FIGS. 2A to 2C, floating substances floating on the water surface of the bathtub can be collected in the container 10.

After collecting the suspended matter in the container 10 in this way, when the suspended matter removing tool 1 is finally lifted from the water surface of the bathtub as shown in FIG. It is discharged through 20 and the suspended matter remains in the filter section 20. Since the lower surface of the container 10 is inclined downward from the outer edge toward the central circulation hole 11, the water in the container 10 flows to the circulation hole 11 along the inclination, whereby the suspended matter is filtered. It is easy to accumulate in 20. Further, since the filter unit 20 can be removed and cleaned, it is easy to dispose of the suspended matter accumulated in the filter unit 20.

As described above, in the floating material remover 1 of the first embodiment, the user manually submerges the water in the vicinity of the water surface of the bath 10 from the upper outer edge of the container 10 in the container 10 together with the floating material. When the user releases his hand, the air floats in the air chamber 12 due to the buoyancy of the air, causing a difference in water level between the water surface inside the container 10 and the water surface inside the bathtub. Then, in order to eliminate this difference in water level, the water in the container 10 flows out from the circulation holes 11 on the lower surface and is filtered by the filter section 20. Therefore, it is possible to easily remove the suspended matter floating on the water surface of the bathtub without needing to secure a power source or ensure waterproofness.

FIG. 3 is a perspective view showing a state in which the suspended solid removing tool 1 of the second embodiment is disassembled. The same components as those in the first embodiment described above are designated by the same reference numerals, and detailed description thereof will be omitted. As shown in the figure, in the suspended matter removing tool 1 of the second embodiment, a disk-shaped movable plate 30 is added to the suspended matter removing tool 1 of the first embodiment. The movable plate 30 has an abutment body 31 formed of a material that floats in water (for example, styrene foam, foamed rubber, sponge, etc.) attached to the lower surface side, and a sliding shaft extending upward from the center of the upper surface. 32 are erected. The movable plate 30 and the contact body 31 of the second embodiment correspond to the "movable member" of the present invention.

On the other hand, in the container 10, there is provided a bearing 13 having an insertion hole 13a at the center through which the sliding shaft 32 is inserted, and a plurality of bearings 13 extending from the lower surface of the container 10 (illustrated example) are provided. It is supported by three (3) legs 13b and is located above the flow hole 11.

The outer diameter of the movable plate 30 is smaller than the inner diameter of the through hole 11, and when the movable plate 30 is installed in the container 10 through the through hole 11, the sliding shaft 32 is inserted into the through hole 13 a of the bearing 13. Then, the sliding shaft 32 slides along the insertion hole 13a to guide the vertical movement of the movable plate 30 in the container 10. In addition, a plurality of outwardly extending protrusions 32a (six in the illustrated example) extending in the axial direction are provided on the outer peripheral surface of the sliding shaft 32, and the protrusion ends of the protrusions 32a are formed on the inner periphery of the insertion hole 13a. By making line contact with the surface, smoother sliding is possible compared to surface contact.

When the movable plate 30 is installed in the container 10 in this manner, the filter portion 20 is attached to the flow hole 11 in the same manner as in the first embodiment described above. The movable plate 30 (sliding shaft 32) is prevented from coming off because it abuts the upper sieve 21 of the portion 20. Further, the outer diameter of the contact body 31 is substantially the same as the outer diameter of the portion where the large mesh of the upper sieve 21 is formed (mesh portion). The part 20 is closed.

FIG. 4 is an explanatory diagram showing an operation of removing the floating material floating on the water surface of the bathtub by using the floating material removing tool 1 of the second embodiment. It should be noted that in FIG. 4, floating objects are not shown. First, FIG. 4A shows a state in which the container 10 is floated on the water surface of the bathtub by the buoyancy of the air in the air chamber 12. At this time, the movable plate 30 moves upward by the buoyancy of the contact body 31 and floats on the water surface in the container 10, and the contact body 31 is separated from the filter section 20.

Next, when the user presses the tip of the sliding shaft 32 from above, the movable plate 30 moves downward against the buoyancy of the contact body 31, and as shown in FIG. The filter unit 20 is closed by the contact of the filter unit 31 with the filter unit 20 (upper sieve 21).

Then, when the user further presses the tip of the sliding shaft 32 in the state where the contact body 31 is in contact with the filter portion 20, the pressure is transmitted to the container 10 and resists the buoyancy of the air in the air chamber 12. The suspended matter removing tool 1 sinks into the water in the bathtub. Then, as shown in FIG. 4C, when the upper end of the container 10 sinks below the water surface of the bathtub, water near the water surface of the bathtub flows into the container 10 from the outer edge of the upper end of the container 10 together with the suspended matter.

At this time, since the filter portion 20 is closed by the contact body 31, the water in the bathtub does not flow into the container 10 from the circulation hole 11 on the lower surface of the container 10, which is the same as the first embodiment described above. In comparison, since the amount of water flowing in from the outer edge of the upper end of the container 10 increases, the suspended matter floating on the water surface of the bathtub can be efficiently taken into the container 10. The abutment body 31 does not have to completely close the filter portion 20 and covers at least a part of the filter portion 20 (mesh portion of the upper sieve 21), so that the inflow of water from the circulation hole 11 can be achieved. Is suppressed, it is possible to promote the inflow of water from the outer edge of the upper end of the container 10.

After the water is taken in the container 10 in this way, when the user releases the sliding shaft 32 to release the pressure, the movable plate 30 is moved by the buoyancy of the contact body 31 as shown in FIG. When the contact body 31 moves upward and moves away from the filter section 20, the filter section 20 is opened. The restoring force that returns the movable plate 30 to the upper side is not limited to the buoyancy of the contact body 31, and a biasing member such as a spring that biases the movable plate 30 upward may be installed. The biasing force of the biasing member may be used as the restoring force.

Further, the buoyancy of the air in the air chamber 12 causes the container 10 to float above the water surface of the bathtub, and the water surface inside the container 10 becomes higher than the water surface of the bathtub, causing a water level difference. Since the water in the container 10 flows out from the circulation hole 11 on the lower surface of the container 10 and is filtered by the filter unit 20 so as to eliminate this difference in water level, the water from which the suspended matter has been removed returns to the bathtub. Then, when the water level difference between the water surface in the container 10 and the water surface in the bathtub disappears, the outflow of water in the container 10 stops and the state shown in FIG. 4A is restored.

As described above, in the floating material remover 1 of the second embodiment, similarly to the first embodiment described above, the floating material floating on the water surface of the bathtub can be removed without the need to secure the power source or secure the waterproof property. It can be easily removed. When the user presses the tip of the sliding shaft 32 when submerging the floating substance removing tool 1 in the water of the bathtub, the movable plate 30 moves downward and the contact body 31 closes the filter portion 20. Since the inflow of water from the circulation hole 11 opened on the lower surface of the container 10 is suppressed, it is possible to increase the inflow amount of water from the outer edge of the upper end of the container 10 and efficiently take the suspended matter on the water surface of the bath into the container 10. It will be possible.

Further, in the suspended matter removing tool 1 of the second embodiment, since the buoyancy of the contact body 31 is used as the restoring force for returning the movable plate 30 upward when the pressure is released, another member such as a spring is used. The restoring force can be easily obtained without the need for.

FIG. 5 is a perspective view showing a state in which the suspended matter removing tool 1 of the third embodiment is disassembled. In FIG. 5, the filter portion 20 is already attached to the flow hole 11 of the container 10. As shown in the figure, in the floating substance removing tool 1 of the third embodiment, the upper and lower sides of the floating substance removing tool 1 of the first embodiment are closed and the lower surface is opened. 40 and a support member 42 that supports the inner trough 40 in the container 10 so as to be vertically movable. The inner tub 40 of the third embodiment corresponds to the "box-shaped body" of the present invention.

The inner diameter of the inner trough 40 is larger than that of the through hole 11 on the bottom surface of the container 10. Further, on the outer side of the inner tub 40, there is provided a frame body 40a formed in an annular shape having an outer diameter smaller than the inner diameter of the container 10, and a plurality of (in the example shown in the figure, six) radially arranged at equal intervals is provided. ) Spokes 40b are connected.

The support member 42 has an annular outer ring 42a whose outer diameter is substantially the same as the inner diameter of the container 10 and an annular inner ring 42b whose inner diameter is larger than the outer diameter of the inner trough 40. Inner ring 42b is located inside 42a, and is connected by a plurality of (six in the illustrated example) connecting ribs 42c radially arranged at equal intervals.

The support member 42 is fixed by press-fitting the outer ring 42a inside the container 10 with the inner trough 40 inserted from the bottom inside the inner ring 42b. As a result, the inner tub 40 can move up and down inside the inner ring 42b, and when the inner tub 40 moves upward, the spokes 40b come into contact with the inner ring 42b to prevent the inner tub 40 from coming off. Further, when the inner tub 40 is tilted, the frame body 40a contacts the connecting rib 42c of the support member 42, so that the inner tub 40 can be prevented from being greatly tilted.

FIG. 6 is an explanatory view showing an operation of removing the floating material floating on the water surface of the bathtub by using the floating material removing tool 1 of the third embodiment. It should be noted that in FIG. 6, floating objects are not shown. First, FIG. 6A shows a state in which the container 10 is floated on the water surface of the bathtub by the buoyancy of the air in the air chamber 12. At this time, the lower surface of the inner tub 40 is closed by the water surface in the container 10, and the buoyancy of the air stored in the inner tub 40 floats the inner tub 40 on the water surface in the container 10. Away from.

Next, when the user presses the upper surface of the inner trough 40 from above, the inner trough 40 moves downward against the buoyancy of the air in the inner trough 40, and the lower end of the inner trough 40 is lowered as shown in FIG. 6(b). It contacts the lower surface of the container 10. As described above, since the inner diameter of the inner tub 40 is larger than that of the through hole 11, the through hole 11 (filter portion 20) is covered with the inner tub 40. Further, as the inner tub 40 moves downward, part of the water in the container 10 is pushed out from the circulation hole 11.

When the user further presses the upper surface of the inner tub 40 with the lower end of the inner tub 40 in contact with the lower surface of the container 10, the pressure is transmitted to the container 10 and floats against the buoyancy of the air in the air chamber 12. The object remover 1 sinks into the water of the bathtub. Then, as shown in FIG. 6C, when the upper end of the container 10 sinks below the water surface of the bathtub, the water near the water surface of the bathtub from the outer edge of the upper end of the container 10 floats between the container 10 and the inner tub 40. Flow into.

At this time, since the circulation hole 11 (filter portion 20) on the lower surface of the container 10 is covered with the inner tub 40, the water in the bathtub is prevented from flowing into the container 10 through the circulation hole 11, and the first embodiment described above is performed. As compared with the example, the inflow amount of water from the outer edge of the upper end of the container 10 increases, so that the suspended matter floating on the water surface of the bathtub can be efficiently taken into the container 10.

After the water is taken in between the container 10 and the inner tub 40 in this way, when the user releases the pressure from the inner tub 40 by releasing the hand, the buoyancy of the air in the inner tub 40 is exerted as shown in FIG. 6D. The inner tub 40 moves upward, and the lower end of the inner tub 40 is separated from the lower surface of the container 10, so that the flow hole 11 (filter portion 20) is not covered with the inner tub 40. In addition, since the upper surface of the inner tub 40 is formed in a spherical shape convex upward and the center is higher than the outer edge, it is difficult for the water taken into the container 10 to remain on the upper surface of the inner tub 40 and the container 10 and the inner tub 40. Flows to and from.

Further, the buoyancy of the air in the air chamber 12 causes the container 10 to float above the water surface of the bathtub, and the water surface between the container 10 and the inner tub 40 becomes higher than the water surface of the bathtub, causing a water level difference. Since the water in the container 10 flows out from the circulation hole 11 on the lower surface of the container 10 and is filtered by the filter unit 20 so as to eliminate this difference in water level, the water from which the suspended matter has been removed returns to the bathtub. Then, when the water level difference between the water surface inside the container 10 and the water surface in the bathtub disappears, the outflow of water inside the container 10 stops and the state shown in FIG. 6A is restored.

As described above, in the floating material remover 1 of the third embodiment, similarly to the first embodiment described above, the floating material floating on the water surface of the bathtub can be removed without the need for securing a power source and ensuring waterproofness. It can be easily removed. Then, as in the case of the second embodiment, the inner trough 40, which is moved downward by the pressure of the user when the suspended matter removing tool 1 is submerged in the water of the bathtub, covers the flow hole 11 (the filter portion 20), whereby the container 10 is obtained. It is possible to increase the inflow amount of water from the outer edge of the upper end of the above and efficiently take the suspended matter on the water surface of the bath into the container 10. In addition, since the buoyancy of the air in the inner tub 40 is used as the restoring force for returning the inner tub 40 to the upper side when the pressure is released, a separate member such as a spring is not required, and the restoring force can be easily obtained. You can

Furthermore, in the floating material removal tool 1 of the third embodiment, the floating material diffused into the water by the force of water flowing from the upper outer edge of the container 10 flows from between the container 10 and the inner tub 40 to the lower end of the inner tub 40 together with the water. It flows through the inside of the inner tub 40 and is filtered by the filter portion 20 of the flow hole 11. When the water level difference between the water surface in the container 10 and the water surface in the bathtub disappears and the outflow of water from the circulation hole 11 stops, as shown in FIG. 7, the suspended matter that has once flowed into the inner trough 40 is Even if it floats on the water surface in the container 10, it is difficult to return to the outside of the inner tub 40 by being blocked by the side wall of the inner tub 40, so that the suspended matter can be kept inside the inner tub 40. As a result, even if the operation of sinking the floating material removal tool 1 is repeated, it is possible to suppress the floating material collected in the container 10 (inside the inner trough 40) from returning from the upper outer edge of the container 10 to the water surface of the bathtub.

In addition, the floating matter removing tool 1 of the third embodiment has the following modifications. FIG. 8 is an enlarged sectional view showing the vicinity of the lower end of the inner tub 40 in the modification of the third embodiment. As shown in the drawing, an annular packing 45 made of an elastic material such as rubber is attached to the lower end of the inner tub 40 of the modified example. Then, when the user presses the upper surface of the inner tub 40 from above, the packing 45 comes into contact with the lower surface of the container 10 and comes into close contact therewith. As a result, the flow of water from the inside to the outside of the inner trough 40 is blocked, so that when the container 10 is submerged in the water of the bathtub, it is possible to further suppress the water in the bathtub from flowing into the container 10 from the circulation hole 11. You can

FIG. 9 is a perspective view showing the shape of the container 10 in the suspended matter removing tool 1 of the fourth embodiment. The floating material remover 1 of the fourth embodiment is common with the third embodiment described above in that it has the inner tub 40 and the support member 42, and the shape of the container 10 is partially different. As shown in the figure, the container 10 of the fourth embodiment is provided with a cylindrical standing wall 15 that surrounds the flow hole 11 and stands upward from the lower surface. A plurality of vertical slits 15a (four in the illustrated example) are formed on the standing wall 15 at equal intervals.

FIG. 10: is explanatory drawing which showed the example which removes the floating material floating on the water surface of a bathtub using the floating material removal tool 1 of 4th Example. FIG. 10A shows a state in which the suspended matter removing tool 1 once submerged in the water of the bathtub by the user's pressure floats to the water surface of the bathtub by the buoyancy force as in FIG. 6D. The water in the container 10 flows out from the circulation hole 11 on the lower surface of the container 10 and is filtered by the filter unit 20 so that the water level difference between the inner tub 40 and the inner tub 40 is higher than the water level of the bathtub.

As shown in the figure, the erected wall 15 erected from the lower surface of the container 10 is located inside the inner tub 40, and the upper end of the erected wall 15 is higher than the lower end of the inner tub 40 that has returned upward due to buoyancy. positioned. Further, the upper end of the standing wall 15 is located slightly below the bath surface in a state where the container 10 floats on the bath surface. Then, when the floating substances are diffused when flowing in from the outer edge of the upper end of the container 10, the water accumulated between the container 10 and the inner tub 40 receives the water pressure corresponding to the water level difference with the water surface of the bathtub, and thus the water shown in FIG. As indicated by the thick arrow in the drawing, when passing through the lower end of the inner trough 40 that has returned upward, further passing the upper end of the standing wall 15 to the inside of the standing wall 15 and flowing out from the flow hole 11. It is filtered by the filter unit 20.

Thereafter, as shown in FIG. 10B, when the water level difference between the water surface in the container 10 and the water surface of the bathtub disappears and the outflow of water from the circulation hole 11 stops, the water flows from the inside of the standing wall 15 to the outside. Since the movement of water is blocked by the standing wall 15, it is difficult for the suspended matter once flowing inside the standing wall 15 to return to the outside of the standing wall 15, and compared with the third embodiment described above, It is possible to further suppress the floating matter from returning to the inner tub 40.

Further, since the standing wall 15 is erected from the lower surface of the container 10 so as to surround the circulation hole 11, when the container 10 is submerged in the water of the bathtub, the inside of the trough 40 is changed from the inside of the standing wall 15 to the outside. Since the flow of the water is blocked, the effect of further suppressing the water in the bathtub from flowing into the container 10 from the circulation hole 11 can be obtained as compared with the third embodiment.

Furthermore, after collecting the suspended solids in the container 10, when the suspended solid removal tool 1 is finally lifted from the water surface of the bathtub (see FIG. 2D), the suspended solid removal tool 1 of the fourth embodiment stands upright. Since the plurality of slits 15a are formed in the wall 15, water outside the standing wall 15 in the container 10 flows into the circulation holes 11 through the slits 15a, so that the water in the container 10 flows. It is possible to discharge all from 11. It should be noted that the slit 15a of the standing wall 15 is not essential for collecting the suspended matter in the container 10.

In addition, the floating matter removing tool 1 of the fourth embodiment has the following modifications. FIG. 11 is an enlarged cross-sectional view showing the vicinity of the lower end of the inner tub 40 in the first modification of the fourth embodiment. As shown in the figure, at the lower end of the inner trough 40 in the first modified example, there is attached a fin member 47 which is formed of an elastic material such as rubber in a ring shape and whose inner diameter is reduced downward. When the inner trough 40 is moved downward by the pressure of the user, the fin member 47 comes into contact with the lower surface of the container 10 to be in close contact therewith, like the packing 45 (see FIG. 8) in the modification of the third embodiment described above.

When the user's pressure is released and the inner tub 40 returns upward due to buoyancy, the fin member 47 scrapes up the water between the inner tub 40 and the erected wall 15 to cause the inner tub 40 and the erected wall to rise. It is possible to obtain the effect of sending the floating substances floating between 15 and 15 into the inside of the standing wall 15 together with water.

FIG. 12 is an enlarged sectional view showing the vicinity of the upper end of the standing wall 15 in the second modification of the fourth embodiment. As shown in the drawing, an annular diameter reducing member 16 having an inner diameter smaller than that of the standing wall 15 is externally fitted and attached to the upper end of the standing wall 15 in the second modification. By covering the standing wall 15 inward from the upper end of the standing wall 15 with such a diameter-reducing member 16, it is difficult for the suspended matter once flowing into the standing wall 15 to return to the outside beyond the upper end of the standing wall 15. Therefore, it is possible to further prevent the floating substances from returning between the container 10 and the inner tub 40.

FIG. 13 is a perspective view showing a state in which the suspended matter removing tool 1 of the fifth embodiment is disassembled. In addition, in FIG. 13, the filter portion 20 is already attached to the flow hole 11 of the container 10. As shown in the figure, in the floating material remover 1 of the fifth embodiment, a cylindrical isolation wall 50 whose upper surface and lower surface are both opened is added to the floating material remover 1 of the first embodiment. There is.

The inner diameter of the isolation wall 50 is larger than the through hole 11 on the bottom surface of the container 10. Further, on the outside of the isolation wall 50, there is provided an annular frame 50a having an outer diameter substantially the same as the inner diameter of the container 10, and a plurality of radially arranged equal intervals (the illustrated example). 6) are connected by the spokes 50b. Then, the isolation wall 50 is fixed by press-fitting the frame body 50 a inside the container 10. Thereby, the inside of the container 10 is separated into the inside and the outside of the isolation wall 50.

FIG. 14: is explanatory drawing which showed the operation|movement which removes the floating material floating on the water surface of a bathtub using the floating material removal tool 1 of 5th Example. It should be noted that in FIG. 14, floating substances are not shown. First, FIG. 14A shows a state in which the suspended matter removing tool 1 floats on the water surface of the bathtub by the buoyancy of the air in the air chamber 12. As shown, the upper end of the isolation wall 50 fixed in the container 10 is located above the upper end of the container 10. Further, the lower end of the isolation wall 50 is separated from the lower surface of the container 10 and is located below the water surface in the container 10 in a state where the water level in the container 10 matches the bath water level.

Next, the user manually submerges the suspended matter removing tool 1 in the water of the bathtub against the buoyancy of the air in the air chamber 12, and as shown in FIG. When the upper end of the container 10 is sunk below the bath water surface in a state where the container 10 protrudes above the bath water surface, the water near the water surface of the bath from the outer edge of the upper end of the container 10 flows between the container 10 and the isolation wall 50 together with the suspended matter. Pour in between. At this time, the floating material diffuses into the water with the force of flowing. Then, the water flowing between the container 10 and the isolation wall 50 flows through the lower end of the isolation wall 50 into the isolation wall 50 so that the water levels of the inside and the outside of the isolation wall 50 match.

After the water is taken into the container 10 in this way, when the user releases the floating substance removing tool 1, the floating substance removing tool 1 floats on the water surface of the bathtub due to the buoyancy of the air in the air chamber 12, and FIG. As shown in, the water level inside the container 10 becomes higher than the water level of the bathtub, and a water level difference occurs. Since the water in the container 10 flows out from the circulation hole 11 on the lower surface of the container 10 and is filtered by the filter unit 20 so as to eliminate this difference in water level, the water from which the suspended matter has been removed returns to the bathtub. When the water level difference between the water surface inside the container 10 and the water surface inside the bathtub disappears, the outflow of water inside the container 10 stops and the state shown in FIG. 14A is restored.

As described above, in the floating material remover 1 of the fifth embodiment, similarly to the first embodiment described above, the floating material floating on the water surface of the bathtub can be removed without the need to secure the power source or guarantee the waterproofness. It can be easily removed. Then, once the floating substances diffused in the water through the outer edge of the upper end of the container 10 pass through the lower end of the isolation wall 50 and flow inside the isolation wall 50, as shown in FIG. Even if the outflow of water from 11 is stopped and the floating material floats on the water surface in the container 10, it is difficult for the floating material to return to the outside of the isolation wall 50 because of being blocked by the isolation wall 50. Can be kept inside. As a result, even if the operation of sinking the floating substance removing tool 1 is repeated, it is possible to prevent the floating substances collected in the container 10 (inside the isolation wall 50) from returning from the upper outer edge of the container 10 to the bath surface.

Although the upper surface of the isolation wall 50 of the fifth embodiment is open, the upper surface may be closed. In that case, it is similar to the case where the inner tub 40 of the third embodiment is fixed so as not to move up and down, the buoyancy of the air accumulated in the isolation wall 50 is obtained, and the same as the fifth embodiment described above. In addition, the suspended matter that once flows into the isolation wall 50 can be retained inside the isolation wall 50. Further, the upper end of the isolation wall 50 that closes the upper surface may be located below the upper end of the container 10. On the other hand, when the upper surface of the isolation wall 50 is left open as in the fifth embodiment described above, water can be stored inside the isolation wall 50, so that water in the container 10 can be stored. The amount of uptake can be increased.

In addition, the floating matter removing tool 1 of the fifth embodiment has the following modifications. FIG. 16: is explanatory drawing which showed the example which removes the floating material floating on the water surface of a bathtub using the floating material removal tool 1 of the modification of 5th Example. The container 10 of the modified example is provided with a cylindrical standing wall 15 that surrounds the through hole 11 and stands upward from the lower surface, similarly to the fourth embodiment described above (see FIG. 9 ). FIG. 16A shows a state where the floating substance removing tool 1 once submerged in the water of the bathtub by the user is floated to the water surface of the bathtub by the buoyancy similarly to FIG. 14C, and the water surface of the container 10 is shown. The water in the container 10 flows out from the circulation hole 11 on the lower surface of the container 10 and is filtered by the filter unit 20 so as to eliminate the difference in water level between the water surface of the bathtub and the water surface of the bathtub.

As shown in the drawing, the standing wall 15 that is erected from the lower surface of the container 10 is located inside the isolation wall 50, and the upper end of the standing wall 15 is located above the lower end of the isolation wall 50. .. Then, the water flowing from the outer edge of the upper end of the container 10 between the container 10 and the isolation wall 50 to diffuse the suspended solids flows into the lower end of the isolation wall 50 as indicated by a thick arrow in FIG. After passing through the upper end of the standing wall 15 and further into the inside of the standing wall 15 through the passage, it is filtered by the filter portion 20 when flowing out from the flow hole 11.

After that, as shown in FIG. 16B, when the water level difference between the water surface in the container 10 and the water surface in the bathtub disappears and the outflow of water from the circulation hole 11 stops, the water flows from the inside of the standing wall 15 to the outside. Since the movement of the water is blocked by the standing wall 15, it is difficult for the suspended matter once flowing inside the standing wall 15 to return to the outside of the standing wall 15, and the suspended matter is formed between the container 10 and the isolation wall 50. It is possible to further suppress the return.

Further, as described above, the upper surface of the isolation wall 50 may be closed, and in this case, the standing wall 15 is erected from the lower surface of the container 10 so as to surround the circulation hole 11 so that the container 10 is closed. When submerged in the water in the bathtub, the flow of water from the inside of the standing wall 15 to the outside is blocked inside the isolation wall 50, so that the effect of suppressing the water in the bathtub from flowing into the container 10 from the circulation hole 11 is achieved. Is obtained.

Although the suspended matter removing tool 1 of various embodiments (first to fifth embodiments) and modifications have been described above, the present invention is not limited to the above-described embodiments and modifications, and the gist thereof It is possible to implement in various modes without departing from the above.

For example, in the above-described embodiment, the shape of the container 10 is circular, but the shape is not limited to circular and may be rectangular. Correspondingly, the shape of the flow hole 11, the filter unit 20, the movable plate 30, the inner trough 40, the standing wall 15, the isolation wall 50, etc. is not limited to a circular shape, and may be a rectangular shape. Good.

Further, in the above-described embodiment, the inside of the air chamber 12 and the inside of the inner tub 40 are cavities for accumulating air. It may be packed.
