Description

[Technical field]

[0001] The present invention relates to an ultrafine mechanism generating part for installation in a flow path for water, etc., which can generate and add ultrafine bubbles to water, etc. by being installed in the flow path through which water, etc. flows. [Background technology]

[0002] Currently, many techniques have been published that add ultrafine bubbles to water, etc., to enable sufficient cleaning using only water, etc., to which ultrafine bubbles have been added, without using cleaning agents such as surfactants, or facial soap, etc. Techniques for adding ultrafine bubbles include, for example, a method of adding ultrafine bubbles directly from the outside to water, etc., flowing through a flow path, or a method of installing an ultrafine bubble generator in the flow path and adding the bubbles directly to the water, etc., flowing through the flow path.

[0003] For example, in JP 2019-025451 A (Patent Document 1), a fine bubble water generator 1A is connected to the water supply side end of a shower hose 2 at the first cylindrical portion 4 of the main body case 10, and to the water intake side end of a shower head 3 at the second cylindrical portion 5, a water intake plate 7 having a plurality of water intake holes 11 drilled therein is fitted into the first cylindrical portion 4, and a nozzle arranged downstream of the water intake plate 7 consists of a first water passage 8a whose diameter gradually decreases along the flow direction of the tap water flowing through the water intake plate 7, and a second water passage 8b which is connected to the outlet side of the first water passage 8a and whose diameter gradually increases along the flow direction of the tap water, and a technology is proposed in which the central axis of the water intake hole 11 from the inlet side to the outlet side is inclined with respect to the central axis of the water intake plate 7.

[0004] In addition, JP 2022-063995 A (Patent Document 2) proposes a technology in which a shower hose with a fine bubble water generator that can be attached to a shower facility in which at least one end of the shower hose 10 is detachably attached to a shower head 11 or a water supply tap 12 via a connecting fitting 13 comprises a fine bubble generator, a shower head mounting portion that can be detachably connected to the water supply inlet of the shower head 11, a water supply tap mounting portion that can be detachably connected to the water outlet 12a of the water supply tap 12, and a mounting fixture, wherein the mounting fixture has a first connecting portion that can be connected to either the shower head mounting portion or the connecting fitting 13, and a second connecting portion at the other end that can be connected to either the water supply tap mounting portion or the connecting fitting 13.

[0005] Among the techniques for adding ultrafine bubbles to water or the like flowing through a flow channel, the following problems can be cited for the technique that uses a device installed in the flow channel. (A) Although the device is to be installed within a flow path, it is difficult to reduce the size of the device due to factors such as the large number of parts it has, and as a result, the flow paths in which it can be installed are limited, or it has to be installed at the end of the flow path. (a) In addition, as the size of the equipment becomes smaller, the cost of each component tends to increase. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2019-025451 A [Patent Document 2] Patent Publication No. 2022-063995 Summary of the Invention [Problem to be solved by the invention]

[0007] The problem that the present invention aims to solve is to provide an ultrafine bubble generating part that can be installed in any flow path while reducing the number of parts of the device and suppressing implementation costs, and that can add ultrafine bubbles to the water or the like flowing in the flow path. [Means for solving the problem]

[0008] As a means for solving the above-mentioned problems, the ultrafine bubble generating part of the present invention, which is installed in a flow path of water, etc., is an ultrafine bubble generating part which is installed in a flow path of water, etc., and which comprises a flat part body and one or more fine holes formed in appropriate positions of the part body, and which is installed in the flow path of water, etc., so that ultrafine bubbles are added to the water, etc., as the water, etc. passes through the fine holes formed in the part body.

[0009] The ultrafine bubble generating part of the present invention, which is installed inside a flow path for water, etc., is characterized in that the central axis of the pore is inclined at a predetermined angle from the central axis of the direction of travel of the water, etc. in the flow path, so that the water, etc. that has passed through the pores in the part body is released from the pores in an arbitrary spiral.

[0010] The ultrafine bubble generating part of the present invention, which is to be installed inside a flow path for water or the like, is also characterized in that the hollow interior forming the pores is tapered from the upstream side of the water or the like to the downstream side.

[0011] In the ultrafine bubble generating part of the present invention that is installed in a flow path for water, etc., the pores consist of a first pore drilled at the center position of the flat surface of the part body, and a plurality of second pores drilled around the central pore on the flat surface of the part body, and the first pore is characterized in that the hollow interior forming the first pore is formed in an arc shape, so that the water, etc. that has passed through the first pore is released in a spiral shape in a predetermined direction, and the second pore is characterized in that the water, etc. that has passed through the second pore is released in a spiral shape in the opposite direction to the spiral direction of the water, etc. that has passed through the first pore.

[0012] The ultrafine bubble generating part of the present invention is an ultrafine bubble generating part of the type to be installed inside a flow path of water, etc., which is composed of a flat part body and one or more fine holes formed at appropriate positions in the part body, and is characterized in that the central axis of the fine hole is inclined at a predetermined angle from the central axis of the traveling direction of the water, etc. in the flow path, so that the water, etc. that has passed through the fine hole in the part body is released from the fine hole in an arbitrary spiral, and a plurality of the part bodies are installed at predetermined intervals within a single flow path, and the plurality of part bodies are installed so that the spiral directions of the water, etc. that have passed through the part bodies are opposite to each other, so that ultrafine bubbles are added to the water, etc. as the water, etc. passes through the fine holes formed in the part body.

[0013] The effects achieved by the ultrafine bubble generating part of the present invention, which is installed in a flow path for water or the like, include the following. (1) Since ultrafine bubbles can be generated by drilling fine holes in the body of the part that constitutes the present invention, it is extremely easy to reduce the size of the body of the part and to install it in a flow path of any diameter. (2) The present invention is composed only of a part body having fine holes formed therein. By simply installing one or more of the part bodies, it is possible to add ultrafine bubbles to water or the like in a flow path in which the part body is installed, and this can be implemented at extremely low cost. (3) Ultrafine bubbles can be easily added to the water flowing through the flow path, making it possible to eliminate the need for environmentally hazardous cleaning agents such as surfactants and snow-melting agents, and therefore environmentally friendly and without damaging the natural environment. (4) By using water or the like to which the ultrafine bubbles have been added via the ultrafine bubble generating part of the present invention, the high cleaning ability of the ultrafine bubbles allows for sufficient cleaning without the use of detergents that have a high environmental impact, such as surfactants. (5) By using the ultrafine bubble generating part of the present invention, ultrafine bubbles having a diameter of less than 100 μm can be added to the water passing through the ultrafine bubble generating part. In addition, by adjusting the diameter and shape of the pores formed in the ultrafine bubble generating part, ultrafine bubbles having a diameter of less than 1 μm (so-called ultra-fine bubbles) can also be added. (6) The ultrafine bubble generating parts can be installed in any flow path regardless of the diameter of the flow path. Therefore, by adding ultrafine bubbles of the most effective diameter to water or other liquids according to the shape, structure, material, etc. of the object to be cleaned, high cleaning performance can always be achieved regardless of the nature of the object to be cleaned. (7) The ultrafine bubble generating parts can be installed in any flow path regardless of the diameter of the flow path, so they can always demonstrate high cleaning performance in any location or environment, regardless of the location or environment of the object to be cleaned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] The ultrafine bubble generating part of the present invention, which is installed in a flow path for water or the like, will be described in detail with reference to the drawings.

[0016] 1 to 3 show a first embodiment of the ultrafine bubble generating part of the present invention, which is installed in the flow path of water, etc., and is designed to add ultrafine bubbles to the water, etc., flowing in the flow path by using an ultrafine bubble generating part 11 of the type installed in the flow path of water, etc. (hereinafter referred to as ultrafine bubble generating part 11). Note that in the second to fourth embodiments described below, as in the first embodiment, ultrafine bubbles can be added to the water, etc., flowing in the flow path.

[0017] The ultrafine bubble generating part 11 according to the first embodiment of the present invention, as shown in Figures 1 to 3, comprises a flat part body 12 and one or more fine holes 13 formed in appropriate positions of the part body 12. The ultrafine bubble generating part 11 is placed in a flow path 101 for water, etc., and ultrafine bubbles are added to the water, etc. as the water, etc. passes through the pores 13 provided in the part body 12.

[0018] In addition, the central axis 13a of the pore 13 is inclined at a predetermined angle from the central axis 101a of the direction of travel of the water, etc. in the flow path 101, as shown in Figure 2, so that the water, etc. that has passed through the pore 13 of the part body 12 is released from the pore 13 in an arbitrary spiral. In this manner, the water flowing through the flow path 101 collides with the part body 12, passes through the pores 13, and is released in a spiral while colliding with itself or with the inner surface of the pores 13, thereby adding ultrafine bubbles.

[0019] The ultrafine bubble generating part 21 according to the second embodiment of the present invention, as shown in Figures 4 to 6, comprises a flat part body 22 and one or more fine holes 23 formed at appropriate positions in the part body 22. The ultrafine bubble generating part 21 is placed in a flow path 101 for water, etc., and ultrafine bubbles are added to the water, etc. as the water, etc. passes through the pores 13 provided in the part body 22.

[0020] As shown in FIG. 5, the hollow interior 23b forming the pore 23 is tapered from the upstream side of the water or the like to the downstream side. As in the first embodiment, the central axis 23a of the pore 23 is inclined at a predetermined angle from the central axis 101a in the direction of travel of the water, etc. in the flow path 101, so that the water, etc. that has passed through the pore 23 of the part body 22 is released from the pore 23 in an arbitrary spiral. In this manner, the water flowing within the flow path 101 collides with the part body 22, and as it passes through the pore 23, the water collides with itself or with the inner circumferential surface formed at the tapered narrowing of the pore 23 and is released in a spiral shape, adding ultrafine bubbles.

[0021] As shown in Figures 7 to 10, the ultrafine bubble generating part 31 according to the third embodiment of the present invention comprises a flat part body 32, a first hole 33 formed at an appropriate position in the part body 32, and a plurality of holes 34 formed around the first hole 33. The first pore 33 is formed at the center of the flat surface of the part body 32, and the hollow interior 33a forming the first pore 33 is formed so as to describe an arc. In this way, water or the like that passes through the first pore 33 is discharged so as to describe a spiral in a predetermined direction.

[0022] The second pores 34 are configured so that the water, etc. that has passed through the second pores 34 is discharged in a spiral direction opposite to the spiral direction of the water, etc. that has passed through the first pores 33. By doing this, water, etc. passing through one of the part bodies 32 can be simultaneously released in a counter-rotating spiral direction at one of the part bodies 32, enabling a sufficient amount of ultra-fine bubbles to be added. In the third embodiment, the water, etc. that passes through the first pore 33 spirals counterclockwise in the direction of travel, and the water, etc. that passes through the second pore 34 spirals clockwise in the direction of travel. However, of course, the spiral direction may be opposite to that of the first pore and the second pore, and is not limited to that of the third embodiment.

[0023] As shown in Figures 11 to 14, the ultrafine bubble generating part 41 according to the fourth embodiment of the present invention comprises a flat first part body 42, a flat second part body 43, and fine holes 44 formed at appropriate positions in the part bodies 42, 43.

[0024] In this embodiment, the part bodies 42, 43 are arranged at a predetermined distance from each other, as shown in Figure 12, and such that the spiral direction of the water, etc. passing through the part body 43 is opposite to the spiral direction of the water, etc. passing through the part body 42. By doing this, water, etc. that has passed through the part body 42 and been released in a predetermined spiral direction is released in a spiral direction opposite to that of the part body 42 when it passes through the part body 43 installed downstream of the part body 42, and collides with each other, the part bodies 42 and 43, the inner surface of the pore 44, the inside of the flow path 101, etc., so that ultrafine bubbles can be sufficiently added.

[0025] In the first, second and fourth embodiments, the pores 13, 23 and 44 are shown as cylindrical with the inlet and outlet for water etc. having the same diameter, but it goes without saying that they may be formed into a tapered shape as in the third embodiment. Further, although each embodiment is shown to have a substantially cylindrical shape, it goes without saying that it may also have a rectangular column or other streamlined shapes.

[0026] The ultrafine bubble generating part 51 according to the fifth embodiment of the present invention, as shown in Figures 15 to 16(b), comprises a flat part body 52 and one or more fine holes 54 formed in appropriate positions of the part body 52. As shown in FIG. 15, the pores 54 have hollow interiors 54b that form the pores 54, each of which is tapered from the upstream side of the water or the like to the downstream side. As in the first embodiment, the central axis 54a of the fine hole 54 is inclined at a predetermined angle from the central axis of the flow direction of the water or the like in the flow path, so that the water or the like that passes through the fine hole 54 of the part body 52 is discharged from the fine hole 54 in an arbitrary spiral. Furthermore, the downstream discharge outlets of the multiple fine holes 54 are formed closely together at the center position of the downstream face of the part body 52. By doing this, the water flowing through the flow path collides with the part body 52, and as it passes through the pores 54, the water collides with itself and with the inner surface formed at the tapered narrowing of the pores 54 and is released in a spiral shape, adding ultrafine bubbles.

[0027] The ultrafine bubble generating part 51 according to the fifth embodiment of the present invention can be further connected to a release structure 71 as shown in FIG. 16(b). More specifically, as shown in FIG. 16(a), in the past, an ultrafine bubble generating structure was used that consisted of a swirling structure 61 that causes the water flowing through the water flow path to flow in a spiral shape, a compression structure 62 that is installed, for example, downstream of the swirling structure 61, and a release structure 63 that releases the water pressurized by the compression structure 62 with force when the pressure is released, to generate ultrafine bubbles in the water flow and release them with force accompanied by a swirling motion, thereby improving the cleaning ability.

[0028] However, the structure in Fig. 16(a) requires a large number of parts, and there are problems with durability and cost. Therefore, in the fifth embodiment of the present invention, as shown in Fig. 16(b), an ultrafine bubble generating part 51 and a release structure 71 are provided. In this case, the ultrafine bubble generating part 51 has fine holes 54 that are drilled so that the water passing through it is discharged in a spiral direction, and the fine holes 54 are tapered toward the downstream side.

[0029] By arranging the ultrafine bubble generating part 51 on the upstream side of the water flow and the release structure 71 on the downstream side and connecting them together, the water passes through the pores 54 of the ultrafine bubble generating part 51, giving the released water a spiral orientation, and since the pores 54 are formed with a tapered narrowing, a compression effect is applied to the water passing through the pores 54, thereby generating ultrafine bubbles. Therefore, compared to the conventional structure shown in FIG. 16(a), the number of parts can be reduced, durability can be improved, and material costs can be reduced.

[0030] FIG. 17 shows various structures in the emitting portion of the superfine bubble generating part 51 in the fifth embodiment shown in FIG. 16(b). For example, Figure 17(a) is a schematic bottom view of the release portion of the ultrafine bubble generating part 51 with the attachment removed or not formed, and as shown in the figure, multiple release holes 54c are formed closely spaced in the release portion.

[0031] For example, as shown in FIG. 17(b), by attaching or forming a doughnut-shaped attachment 81 to the release portion of the ultrafine bubble generating part 51, the opening portion of the release hole 54c can be made smaller, and the water passing through the release hole 54c can be pressurized, thereby increasing the water pressure. Of course, the shape of the attachment 81 is not limited to that of FIG. 17(b), and it goes without saying that it may have other shapes, such as those shown in FIGS. 17(c) and (d). In this way, by adjusting the opening of the release hole 54c in the release portion of the ultrafine bubble generating part 51, the water pressure of the water released from the release structure can be easily adjusted. [Industrial Applicability]

[0032] According to the ultrafine bubble generating part of the present invention that is installed inside the flow path of water, etc., it is possible to easily add ultrafine bubbles to water, etc., so it goes without saying that it can be applied to cleaning the surfaces of all kinds of objects.
