Description

  The present invention relates to a soap generator using fine bubbles generated by precipitation of gas dissolved in a liquid.

In general, warm bubble baths using bubbles have been known for a long time. Since air is contained in bubbles in a hot bubble bath, it is possible to suppress pressure on the body due to water pressure, as in a general bathing apparatus, and intense temperature transmission to the body. As a conventional method (for example, refer to Patent Document 1), warm bubbles are generated by bubbling by supplying air to water (detergent solution) containing a detergent component by a gas discharge means. Moreover, since it is necessary to keep a body in a fixed temperature range when taking a bath, it is necessary to enlarge the heat capacity of the foam utilized for the foam bath. There has been proposed a bubble bath shower apparatus that uses fine bubbles having a smaller heat bubble size and a larger heat capacity (see, for example, Patent Document 2). According to this method, based on the pressure dissolution method, a gas can be mixed with a liquid by a vortex pump and stirred to generate a gas solution, and fine bubbles can be generated by reducing the pressure of the gas solution. .
JP 2002-339420 A (pages 2 and 3, FIG. 1) Japanese Unexamined Patent Publication No. 2004-261314 (pages 3 to 5, FIG. 1)

  In Patent Document 1, the amount of the detergent solution decreases as the detergent solution in the container is consumed by bubbling by providing the gas ejecting means in the detergent solution, and the amount of the detergent solution is less than the position of the gas ejecting means. Then, bubbles cannot be generated. For this reason, the detergent solution cannot be used completely until the end. In addition, it is difficult to adjust the state of the generated bubbles (for example, the amount of moisture, temperature, etc.).

  Moreover, in patent document 2, since the detergent solution is thrown into the bathtub and the bathtub is also used as a circulation tank, there exists a detergent solution containing a large amount of bubbles in the circulation tank. For this reason, when the detergent solution in the bathtub is circulated through the pump, the air bubbles remaining in the detergent solution are sucked together with the detergent solution into the water supply part (side supplying the liquid to the pump), and aeration (Aeration: inside the pump) In this case, it is difficult to secure a sufficient discharge pressure to generate fine bubbles. In addition, as in Patent Document 1, it is difficult to adjust the state (water content, temperature, etc.) of the generated fine bubbles.

  The present invention has been made in view of the above circumstances, and the first invention is to provide a soap generator that can use a detergent solution without waste, and more stably generate fine bubbles continuously. To do.

  It is an object of the second invention to provide a soap generator capable of continuously generating fine bubbles having a stable quality (water content, temperature).

  The soap generator according to the first aspect of the present invention includes a gas mixing means for mixing gas into the detergent solution flowing through the passage, a moving pressurizing means for moving the detergent solution and pressurizing the detergent solution, and pressurization by the moving pressurizing means. In a soap generating device comprising a foaming means for discharging a formed gas-containing detergent solution to an open environment to generate a soap, the foaming means is located in the detergent solution container for storing the detergent solution and the detergent solution container, and the detergent solution A detergent solution discharge port for discharging the detergent to the suction side of the moving pressure means, a detergent solution supply port that is formed at a predetermined position of the detergent solution container, and supplies the detergent solution into the detergent solution container, and is located in the detergent solution container, A soap supply port for supplying a soap bubble formed by discharging a gas-containing detergent solution to an open environment from the detergent solution supply port to the soap consuming side, and a detergent solution stored in the detergent solution container Liquid level detection means for detecting the liquid level of the liquid level, and the liquid level level by replenishing the replenisher solution in the detergent solution container according to the liquid level detected by the liquid level detection means And a replenishing solution replenishing means for preventing air bubbles formed in the detergent solution in the detergent solution container from being sucked from the detergent solution discharge port.

  According to the soap generator of the first invention, since the liquid level detection means for detecting the level of the liquid level of the detergent solution in the detergent solution container is provided, the capacity of the detergent solution is automatically detected. Can do. Further, the soap generator of the first invention is provided with a replenishing solution replenishing means, so that the replenishing solution is replenished in the detergent solution container according to the liquid level detected by the liquid level detecting means, It is possible to prevent bubbles in the detergent solution in the detergent solution container from being sucked from the detergent solution discharge port due to the liquid level drop. That is, the soap generator of the first invention can adjust or maintain the capacity of the detergent solution (the height of the liquid level) by providing the liquid level detecting means and the replenishing solution replenishing means. That is, by adjusting the level of the liquid level of the detergent solution, among the detergent solutions stored in the detergent solution container, the upper liquid layer containing fine bubbles at a high density and the detergent solution located below The required distance (height) between the container and the detergent solution outlet can be maintained. Therefore, the liquid layer of the detergent solution containing fine bubbles at a high density is hardly sucked from the detergent solution discharge port. Therefore, when the detergent solution is circulated, the liquid discharge pressure of the moving pressurizing unit such as the pump due to the aeration phenomenon can be prevented from being reduced without supplying the liquid containing bubbles to the moving pressurizing unit such as the pump. The performance of the moving pressurizing means such as a pump can be maintained in the best state. As a result, the soap generator according to the present invention can supply a continuously stable quality (soap state) soap bubble.

  In the soap generating device of the first invention, since the replenisher solution is replenished in the detergent solution container according to the level of the liquid level detected by the liquid level detecting means, the level of the liquid level is increased. The effective detergent components in the detergent solution can be used without waste while being maintained. In other words, when the replenishment solution is composed of water or warm water, the detergent solution is diluted by replenishment with water or warm water and consumed while maintaining the predetermined liquid level. Soap can be generated. Therefore, the detergent component in the detergent solution can be used without waste.

  Further, the soap generator of the second invention comprises a gas mixing means for mixing gas into the detergent solution flowing through the passage, a moving pressurizing means for moving the detergent solution and pressurizing the detergent solution, and an application by the moving pressurizing means. In a soap generating device comprising a foaming means for discharging a gas-containing detergent solution formed by pressure into an open environment to generate a soap bubble, the foaming means is disposed at a predetermined position of the detergent solution container for storing the detergent solution and the detergent solution container. A detergent solution supply port that is formed and supplies the detergent solution into the detergent solution container, and a soap bubble that is formed by discharging the gas-containing detergent solution to the open environment from the detergent solution supply port located in the detergent solution container A soap supply port to be supplied to the side, a liquid level detection means for detecting the level of the liquid level of the detergent solution stored in the detergent solution container, and a liquid detected by the liquid level detection means There is provided a soap condition adjusting means for adjusting the level of the liquid level by replenishing the replenisher solution in the detergent solution container according to the liquid level and adjusting the level of the soap bubble supplied from the soap supply port. It is characterized by. Moreover, it is preferable that the bubble state of the bubble produced | generated with the bubble generator of 2nd invention shall be controlled by the liquid content and / or temperature of a bubble.

  According to the soap generator of the second invention, since the liquid level detecting means for detecting the liquid level of the detergent solution and the soap state adjusting means are provided, the capacity of the detergent solution (the height of the liquid level) is automatically set. The detergent solution container is replenished with a replenisher solution according to the level of the liquid level detected by the liquid level detection means, and the level of the detergent solution in the detergent solution container is adjusted. By performing the height adjustment, the soap state (tactile sensation) of the soap supplied from the soap supply port can be adjusted. In other words, the soap generator of the second invention can adjust or maintain the volume of the detergent solution (the height of the liquid surface) by providing the soap state adjusting means. Therefore, fluctuations in the movement time from the generation of bubbles of micro bubbles on the liquid surface of the detergent solution to the bubble supply port located above due to the expansion of the volume of the bubbles (micro bubble foam) are suppressed. The soap state (eg, liquid content, temperature, etc.) can be made uniform. In addition, the liquid level of the detergent solution can be adjusted, so the soap state (eg, liquid content and temperature) of the generated soap can be adjusted by adjusting the distance (height) to the soap supply port. You can also For example, if the liquid level of the detergent solution is adjusted to be within an allowable range, the distance from the liquid level to the soap supply port increases, and after the soap is generated, it is supplied to the soap consumer such as a soap tub or soap shower. The time until it is increased. Thereby, the liquid layer (liquid amount, such as the amount of moisture) of the soap can be reduced, or the temperature of the soap can be lowered. On the other hand, if the liquid level of the detergent solution is adjusted to be high, the time from when the soap is generated until it is supplied to the soap consuming side is shortened, and the liquid layer of the soap (the amount of liquid such as the amount of water) is increased. Or the temperature of the soap bubble can be increased. By adjusting the state of the soap (liquid content), the feel of the soap can be changed and adjusted according to the user's preference.

  Moreover, it is preferable that the size of the soap produced | generated with the soap generator of the 1st, 2nd invention shall be 5-100 micrometers, for example. However, the present invention is not limited to this. Thereby, a fine bubble of a minute unit size can be formed, and a fine gap (space) is formed between the bubbles. Therefore, a structure containing liquid is formed in the soap aggregate formed of fine bubbles, and the heat capacity of the soap is greatly improved, which is advantageous for maintaining the temperature of the bathing of the soap or the soap shower. In addition, since the fine bubbles have a size of a minute unit (for example, a micro unit), the fine bubbles have a higher detergency than normal bubbles, and the body can be cleaned well.

  Moreover, it is preferable to set it as liquid: gas = 4: 6 to 1: 9 contained in the soap produced | generated by the soap generator of the 1st, 2nd invention. However, the present invention is not limited to this. A more natural bathing sensation can be obtained by the ratio of the amount of liquid (water) and gas (air) in the soap aggregate formed by the fine bubbles. That is, if the ratio of the liquid is adjusted to be high, a fluid feeling like a liquid can be given to the user. Further, if the air ratio is adjusted to be high, a fluffy tactile sensation can be given to the user. Therefore, the user can enjoy the soap of his / her favorite feeling.

  According to the soap generator of the present invention, it is possible to adjust or maintain the capacity of the detergent solution (the height of the liquid level) by providing the liquid level detecting means and the replenishing solution replenishing means. That is, by adjusting the level of the liquid level of the detergent solution, among the detergent solutions stored in the detergent solution container, the upper liquid layer containing fine bubbles at a high density and the detergent solution located below A necessary distance between the container and the detergent solution outlet can be maintained, and the liquid layer of the detergent solution containing fine bubbles at high density is hardly sucked from the detergent solution outlet. Therefore, when the detergent solution is circulated, it is possible to prevent a decrease in the liquid discharge pressure of the moving pressurizing means due to the aeration phenomenon without sending the liquid containing bubbles to the moving pressurizing means such as a pump. This is advantageous for improving the performance of the pressure means. As a result, a continuous and stable quality (soap state) soap bubble can be supplied.

  The soap generator of the present invention can include gas mixing means, moving pressure means, and foaming means.

  The gas mixing means of the soap generating apparatus of the present invention introduces gas into the flow path and mixes it. Examples of usable gases generally include air, ozone, carbon dioxide, and aromatic gas. In addition, the gas mixing means can be provided with a gas flow path for introducing gas and an adjustment valve for adjusting the opening and closing of the gas flow path and the flow rate of the gas.

  Further, the moving pressurizing means of the present invention may be any means as long as it can transport, pressurize or circulate the liquid in the liquid passage, such as an impeller circulation pump and a roller pump. In particular, an impeller pump that can make bubbles in a liquid fine by stirring is preferable. Thus, by configuring the moving pressurizing means with a pump or the like, the liquid in the flow path is pressurized and moved. Further, the gas mixed from the gas mixing means is mixed with the liquid by the moving pressurizing means.

  In addition, the foaming means of the present invention is a means for ejecting the gas-containing liquid formed by the moving pressurizing means to an open environment (for example, open to the atmosphere or a decompressed environment) to form fine bubbles. When the gas-containing liquid is ejected into the open environment, the gas is precipitated from the liquid by the reduced pressure, and fine bubbles are generated. When the fine bubbles are detached from the liquid surface of the detergent solution, the shape of the soap is formed by the surfactant contained in the detergent solution.

  Furthermore, the foaming means of the present invention may comprise a detergent solution container, a detergent solution discharge port, a detergent solution supply port, a soap supply port, a liquid level detection means, and a replenishment solution replenishment means. .

  The detergent solution container of the foaming means of the present invention stores a detergent solution. The detergent solution container may include a detergent solution discharge port, a detergent solution supply port, or a soap supply port. The liquid level detecting means detects the height of the liquid level of the liquid in the detergent solution container, and can be constituted by, for example, a liquid level sensor. Further, the liquid level detection means may directly detect the height of the liquid level or indirectly detect the height of the liquid level. Further, the liquid level detection means may be formed integrally with the detergent solution container or may be provided separately from the detergent solution container.

  Further, the detergent solution outlet is an opening for circulating the detergent solution to a moving pressurizing means such as a pump. In order to avoid the aeration phenomenon, it is desirable that the circulating detergent solution is free of bubbles. For this reason, it is preferable to maintain the distance (height) from the upper liquid layer in which fine bubbles are contained in the detergent solution at a high density to the detergent solution discharge port to a predetermined value (range) or more. This predetermined value (range) depends on conditions such as the size of the formed fine bubbles, the rising speed of the bubbles, the viscosity of the detergent liquid, and the temperature, and can be optimized.

  The replenishing solution replenishing means replenishes the replenishing liquid into the detergent solution container in order to maintain the level of the liquid level. Also, by providing a liquid level detection means for detecting the level of the liquid level of the detergent solution in the detergent solution container and a replenishing solution replenishing means for replenishing the replenishing solution, fine bubbles are contained in the detergent solution at a high density. The upper liquid layer is separated from the detergent solution discharge port, and fine bubbles are not sucked from the detergent solution discharge port, which is advantageous for normal operation of the moving pressurizing means. The replenishing solution is preferably composed of a liquid such as water or warm water. Moreover, you may comprise a replenishment solution with a detergent solution.

  Further, the foaming means of the present invention can be provided with a control means for controlling the liquid level detecting means and the replenishing solution replenishing means. Thereby, the liquid level detecting means and the replenishing solution replenishing means can be automatically controlled.

  Moreover, the soap generating apparatus of this invention may be provided with the refinement | miniaturization means which refine | miniaturizes the bubble mixed by the gas mixing means and produces | generates a microbubble. By providing the micronization means, the bubbles have a minute size, the specific area of the liquid in contact with the gas contained in the microbubbles is increased, and the gas can be efficiently dissolved in the liquid.

  Moreover, the soap generating apparatus of this invention may be equipped with the bubble melt | dissolution acceleration | stimulation means which accelerates | stimulates the melt | dissolution to the liquid of the refined | miniaturized microbubble. By providing the bubble dissolution promoting means, the gas can be dissolved in the liquid more efficiently.

  Further, the soap generator of the present invention replenishes the detergent solution container with the replenisher solution according to the level of the liquid level detected by the liquid level detection means, adjusts the level of the liquid level, A soap state adjusting means for adjusting the soap state (liquid content, temperature) of the soap supplied from the soap supply port may be provided. Thereby, the soap state of the generated soap can be adjusted.

  Moreover, it is preferable that the size of the soap produced | generated with the soap generator of this invention shall be 5-100 micrometers. More preferably, it is 10-95 micrometers. More preferably, it is 15-90 micrometers. However, the present invention is not limited to this.

  Moreover, it is preferable to set it as liquid: gas = 4: 6 to 1: 9 contained in the soap bubble | foam produced | generated with the soap generator of this invention. More preferably, it is liquid: gas = 3: 7-2: 8 contained in soap bubbles. However, the present invention is not limited to this.

  Moreover, a bathtub, a hot bubble shower, etc. are mentioned as a soap consumption side of the soap generator of this invention.

  Hereinafter, specific description will be given based on each embodiment.

(Example 1)
This embodiment is shown in FIG. FIG. 1 is an overall conceptual diagram of the soap generator of this embodiment.

  As shown in FIG. 1, the soap generating apparatus of the present embodiment is connected and communicated with a circulation passage 5, and in the order of the flow path, the gas mixing means 1, the moving pressurizing means P, the bubble refining means 2, and the bubble dissolution promoting means 3 , Foaming means 4 and bathtub W. The circulation passage 5 is constituted by a communication pipe. Moreover, the bathtub W is the soap consumption side of the present invention, and is open to the atmosphere.

  In the present embodiment, the foaming means 4 includes a detergent solution container 40. Moreover, the detergent solution stored in the detergent solution container 40 is circulated and used. In the case where the detergent solution is used without being circulated, it may not be the liquid circulation type as in this embodiment. The detergent solution used in this example is prepared with water or warm water, and may be referred to as a liquid hereinafter.

  In addition, since the soap generating apparatus of the present embodiment is a circulation type, the detergent solution container 40 includes a detergent solution discharge port 41 and a detergent solution supply port 42, and one end of the connection passage 401 constituting the circulation passage 5. 401a. Since the detergent solution to be discharged is circulated and used, the detergent solution discharge port 41 functions as a liquid intake portion (41) described later. The detergent solution discharge port 41 is a discharge port provided at the bottom of the detergent solution container 40 as shown in FIG. The detergent solution supply port 42 is provided on the side wall of the detergent solution container 40. The detergent solution supply port 42 has a structure capable of discharging the liquid in the circulation passage 5 while appropriately maintaining the pressure generated in the circulation passage 5 when the moving pressurizing means (pump) P is operated. Yes. Specifically, the inner diameter decreases toward the discharge side (downstream side). Note that the aperture configuration is not limited, and a porous configuration may be used. With such a configuration, since the space between the moving pressurizing means P and the detergent solution supply port 42 is appropriately pressurized, the promotion of dissolution of gas (bubbles) in the liquid is promoted. Further, since the gas-containing liquid is discharged from the detergent solution supply port 42 into the detergent solution container 40, the liquid in which the gas is dissolved is released from pressure, and thus fine bubbles are generated in the detergent solution container 40.

  As shown in FIG. 1, in this embodiment, the gas mixing means 1 includes a first throttle portion (for example: a Venturi tube) 11 whose inner diameter is reduced along the flow direction of the flow path, a gas introduction passage 101, Connection passages 401 and 102 are provided. The gas introduction passage 101 introduces gas into the first throttle unit 11 and mixes the gas into the first throttle unit 11. The connection passages 401 and 102 constitute a part of the circulation passage 5. One end 401 a of the connection passage 401 is communicated with the detergent solution outlet 41 of the detergent solution container 40, and the other end 401 b is communicated with the first throttle portion 11 of the gas mixing means 1. The gas introduction passage 101 is provided with a gas amount adjusting means 12 such as an adjustment valve or an electromagnetic valve for adjusting the flow rate of the introduced gas. On the other hand, the first throttle portion 11 is connected to the circulation passage 5 via the connection passages 401 and 102. The gas mixing means 1 communicates with the liquid intake part (detergent solution discharge port) 41 through the connection passage 401. With such a configuration, since the liquid passing through the inside of the first throttle unit 11 is accelerated, gas is mixed into the first throttle unit 11 through the gas introduction passage 101 due to the negative pressure generated in the first throttle unit 11. Bubbles are formed.

  The gas mixing means 1 may be arranged between the moving pressurizing means P and the liquid intake part 41 described later, or between the moving pressurizing means P and the bubble miniaturizing means 2 described later. Good.

  The gas mixing means 1 is not limited to that described above, and any gas mixing means may be used as long as gas is mixed into the circulation passage 5. In the present embodiment, air is used as the gas mixed from the gas mixing means 1, but the present invention is not limited to this, and other gases such as ozone, carbon dioxide gas, fragrance gas, and the like can be used. .

As shown in FIG. 1, the pump that is the moving pressurizing means P is disposed in the circulation passage 5 between the gas mixing means 1 and the bubble refining means 2. By operating the moving pressurizing means P, the detergent solution is pressurized between the moving pressurizing means P and the detergent solution supply port 42. In this embodiment, the fluid pressure to the detergent solution supply port 42 is about 4 kgf / cm ² . The moving pressurizing means P is connected to the connection passages 102 and 201 and connected to the liquid circulation channel 5. The connection passage 102 communicating with the moving pressurizing means P is the suction side of the moving pressurizing means P of the present invention.

  Further, the gas mixing means 1 and the moving pressure means P are automatically controlled by the control means 6A.

  The bubble refining means 2 of the present invention is shown in FIG. As shown in FIG. 2, the bubble refining means 2 includes a flow path constituted by a second throttle part 29 and an open part 25 communicating with the detergent solution supply port 42 side of the second throttle part 29.

  Inside the bubble refining means 2, a flow path is formed through which the bubble-containing liquid flows from the liquid intake portion 41 side to the detergent solution supply port 42.

  Specifically, as shown in FIG. 2, the bubble refining means 2 includes, in order toward the detergent solution supply port 42, a connecting portion 28 for connecting to the connecting passage 201 on the liquid intake portion 41 side, and a connecting passage 201. A guide space 27 for guiding the detergent liquid from the second throttle portion 29 to the second throttle portion 29, a second throttle portion 29, an opening portion 25, and a connecting portion 30 for connecting to the connection passage 202 on the detergent solution supply port 42 side. ing.

  The connection passages 201 and 202 constitute a part of the circulation passage 5. In addition, the microbubbles of the present invention refer to bubbles that are small enough to have sufficient solubility in a liquid (the specific surface area is large) in the bubble dissolution promoting means 3 described later. The fine bubbles generated by discharging the detergent solution supply port 42 to the detergent solution container 40 are bubbles smaller than the fine bubbles.

  As shown in FIG. 2, the guide space 27 includes a conical space 27 a whose inner diameter increases toward the detergent solution supply port 42 side, and a space 27 b that is continuous with the conical space 27 a and has a circular cross section. . Moreover, the connection part 30 is following the open part 25, and internal space is diameter-reduced toward the detergent solution supply port 42 side.

  The second restricting portion 29 is formed in the partition wall 23 that partitions the liquid intake portion 41 side (upstream side) and the detergent solution supply port 42 side (downstream side) in the bubble refining means 2.

  In the present embodiment, the second throttle portion 29 has a sufficiently small cross-sectional area compared to the cross-sectional area of the guide space 27 so that a sufficient flow rate can be imparted to the liquid containing bubbles. .

  The second throttle portion 29 penetrates the partition wall 23 from the liquid intake portion 41 side toward the detergent solution supply port 42 side. In the present embodiment, the second narrowed portion 29 is composed of a plurality of holes 29a and is formed in the partition wall 23 in nine rows by three rows (shown in FIG. 3). 3 is a cross-sectional view taken along a line AA shown in FIG. Note that only one hole 29a may be provided.

  As shown in FIG. 2, the second throttle portion 29 has a shape in which the cross-sectional area decreases toward the detergent solution supply port 42 side. By reducing the cross-sectional area toward the detergent solution supply port 42 side, the bubble-containing liquid passing through the inside of the second throttle portion 29 is sufficiently accelerated. In the present embodiment, the second diaphragm portion 29 has a circular cross-sectional shape and a curved surface shape whose inner surface shape protrudes toward the radial center. With such a shape, bubbles can be accelerated more sufficiently. In addition, although the 2nd aperture | diaphragm | squeeze part 29 is circular in a present Example, not only this but elliptical shape, polygonal shape, etc. may be sufficient.

  In addition, the 2nd aperture | diaphragm | squeeze part 29 may reduce an internal diameter in a taper shape toward the detergent solution supply port 42 side. Further, the second throttle portion 29 may have a cross-sectional area that decreases stepwise toward the detergent solution supply port 42 side. Even if it is such a shape, the same effect as the 2nd aperture part 29 of a present Example is exhibited.

  Further, the opening on the liquid intake part 41 side of the second throttle part 29 may be formed in an R shape or be chamfered. With such a configuration, bubbles easily flow into the second throttle portion 29.

  The opening part 25 is provided continuously on the detergent solution supply port 42 side of the second throttle part 29. The cross-sectional area of the open portion 25 is larger than the cross-sectional area of the second throttle portion 29 to such an extent that a flow velocity gradient that can be miniaturized is given to the bubbles that have moved from the second throttle portion 29. That is, the cross-sectional area of the opening part 25 is larger than the cross-sectional area of the second throttle part 29 to the extent that the bubbles are rapidly decelerated and refined when the bubbles move from the second throttle part 29 to the opening part 25. ing.

  Moreover, as shown in FIG. 2, the open part 25 is a space with a circular cross-sectional area. Further, the length of the opening 25 toward the detergent solution supply port 42 has a length sufficient for the bubbles that have reached the opening 25 and decelerated to become finer.

  Moreover, the cross-sectional area of the opening part 25 is larger than the cross-sectional area of the internal space of the circulation passage 5 continuous to the detergent solution supply part 42 side. As a result, the flow rate in the opening 25 is sufficiently smaller than the flow rate in the second restrictor 29 and the flow rate in the circulation passage 5 on the detergent solution supply port 42 side. For this reason, a big speed gradient can be given to a bubble.

  By having the opening part 25, the air bubbles that have been accelerated through the second throttle part 29 are decelerated when they reach the opening part 25. Due to this velocity gradient, the bubbles are compressed and refined to generate microbubbles.

  As shown in FIG. 1, the bubble dissolution promoting means 3 includes an inlet 311 through which liquid flows in and an outlet 312 through which liquid flows out. The connection passage 202 is communicated with the inflow port 311, and the connection passage 301 is communicated with the outflow port 312. The connection passages 202 and 301 constitute a part of the circulation passage 5. Thus, the bubble dissolution promoting means 3 is connected to the circulation passage 5 via the connection passages 202 and 301.

Further, as shown in FIG. 1, the bubble dissolution promoting means 3 allows the liquid in the bubble dissolution promoting means 3 to be given a time during which the microbubble-containing liquid can pass and the microbubbles are sufficiently dissolved in the liquid. A detour channel 31 for detouring and a non-dissolved gas collecting unit 32 that collects gas that is provided in the upper part of the bubble dissolution promoting means 3 and does not dissolve in the gas-containing liquid are provided.
The bypass flow path 31 is formed by partitioning the inside of the bubble dissolution promoting means 3 using a member such as a shielding plate. When the bubble-containing liquid passes through the inside of the bubble dissolution accelerating means 3 through the bypass flow path 31, sufficient time for dissolution can be obtained, and the microbubbles are further dissolved in the liquid.

  The non-dissolved gas collecting unit 32 is provided above the bubble dissolution promoting means 3 and collects a gas that is contained in the bubble-containing liquid and does not dissolve (referred to as an excess gas generated by dissolution saturation) by a specific gravity difference. Further, the non-dissolved gas collected by the non-dissolved gas collecting unit 32 (gas that does not dissolve in the liquid) is provided through the non-dissolved gas discharge unit 33 that is provided in the bubble dissolution promoting means 3 and communicates with the non-dissolved gas collecting unit 32. Discharged. Furthermore, the non-dissolved gas discharge unit 33 includes a gas discharge channel 331 that communicates with the bubble dissolution promoting unit 3 and a flow rate adjusting unit 332 that adjusts the gas discharge amount provided in the gas discharge channel 331. The flow rate adjusting means 332 is composed of an open / close valve such as an electromagnetic valve.

  After the gas in the microbubbles is dissolved in the liquid by the bubble dissolution promoting means 3, the gas-containing liquid flows to the foaming means 4 through the connection passage 301. As described above, the circulation passage 5 includes the connection passages 401, 102, 201, 202 and 301.

  As shown in FIG. 4, the gas-containing detergent solution P <b> 2 is discharged from the detergent solution supply port 42 into the detergent solution container 40. The detergent solution container 40 stores the detergent solution P2. When the gas dissolved in the detergent solution P2 is jetted into the detergent solution container 40 through the detergent solution supply port 42, the detergent solution container 40 is brought into the atmosphere. Since it is open, it becomes fine bubbles again by depressurization and is precipitated from the detergent solution P2. The precipitated fine bubbles become soap bubbles P1, forming a soap layer P10.

  As shown in FIG. 4, the detergent solution container 40 is provided with a liquid level detecting means 7 for detecting the liquid level height H1 of the liquid level P20 of the detergent solution P2. The bottom 401 of the detergent solution container 40 is provided with a detergent container discharge port (liquid intake part) 41 for discharging (circulating) the detergent solution P2.

  The detergent solution P2 stored in the detergent solution container 40 includes a liquid-rich liquid layer P21 located in the lower part, a high-density fine bubble layer P22 containing high-density fine bubbles located in the upper part near the liquid level P20, and Consists of.

  When the detergent solution P2 is discharged (circulated), the liquid level height H1 of the liquid surface P20 of the detergent solution P2 is a predetermined position so that the high-density fine bubble layer P22 of the detergent solution P2 is not discharged from the detergent solution discharge port 41. Maintained in range. That is, the replenisher solution (water) is replenished to the detergent solution container 40 in order to maintain the liquid level height H1 of the liquid surface P20 of the detergent solution P2 within the predetermined position range. The replenishing solution is sent from a replenishing solution replenishing means 8 A provided in communication with the detergent solution container 40. The replenishing solution replenishing means 8A includes a replenishing solution inlet 44 provided in the detergent solution container 40 for communication, a replenishing solution storage tank 81 provided above the detergent solution container 40 for storing a replenishing solution, and a replenishing solution inlet 44. A communication channel 801 that communicates with the replenishing solution storage tank 81 and a flow rate adjusting means 82 (valve) that is provided in the communication channel 801 and adjusts the flow rate of the replenishing solution are provided. In this embodiment, the replenishing solution is composed of water or warm water. Note that the replenishment solution can flow into the detergent solution container 40 located below due to its own weight.

  Further, the liquid level detecting means 7 and the replenishing solution replenishing means 8A are automatically controlled by the control means 6B. That is, based on the liquid level information (liquid level height H1) detected by the liquid level detecting means 7, the replenishing solution replenishing means 8A is controlled to automatically replenish the detergent solution container 40 with the replenishing solution. . For this reason, the high-density microbubble layer P22 (high-density microbubble layer height H2) of the detergent solution P2 is always maintained within the allowable position range and is avoided from being sucked into the liquid intake portion 41. The thickness (H1-H2) of the high-density microbubble layer varies depending on the size of the microbubbles, the temperature and viscosity of the detergent solution, and is determined by the properties of the detergent solution actually used.

  The soap P1 formed in the detergent solution container 40 is used by flowing into the bathtub W (shown in FIG. 1) via the soap supply port 43 (shown in FIG. 1). In order to adjust the temperature of the soap bubble P1, a heater 49 may be provided in the circulation passage 5 or the soap supply port 42. By providing the heater 49, the detergent solution in the circulation passage 5 and the detergent solution container 40 can be warmed, and the temperature of the soap bubble P1 formed by the detergent solution can be adjusted.

(Example 2)
This embodiment is basically the same as the configuration of the first embodiment. Hereinafter, a different part from Example 1 is demonstrated. Note that portions similar to those in the first embodiment will be described using the same reference numerals.

  Hereinafter, the soap generator of the present embodiment will be described with reference to FIG. The present embodiment has the same configuration as that of the first embodiment except that the replenishing solution replenishing means 8A described in the first embodiment is different. Specifically, the replenishing solution replenishing means 8A of the first embodiment shown in FIG. 4 can function as the soap state adjusting means 8B of the present embodiment shown in FIG. That is, as shown in FIG. 5, the fine bubbles formed in the detergent solution container 40 are detached upward from the liquid surface P20 of the detergent solution P2, and gather to form a soap layer (soap aggregate) P10. The formed soap layer P10 moves (expands) above the detergent solution container 40 due to the volume expansion of the aggregate, and finally, from the soap supply port 43 provided above the detergent solution container 40, the soap consumption side bath W ( (Shown in FIG. 1). The movement distance H3 of the soap layer P10 from the liquid level P20 to the soap supply port 43 basically affects the temperature and the amount of liquid (generally, the water content) of the soap P1. That is, if the moving distance H3 is large, the liquid component of the soap layer P10 flows down due to gravity, so the liquid layer of the soap bubble P1 decreases, and the temperature of the soap bubble P1 supplied from the soap supply port 43 to the bathtub W decreases. On the other hand, if the moving distance H3 is small, the flow of liquid due to gravity is small, the liquid layer of soap is increased, and the temperature of the soap P1 supplied from the soap supply port 43 to the bathtub W is increased. Accordingly, if the liquid level height H1 of the liquid surface P20 of the detergent solution P2 is adjusted via the soap state adjusting means 8B, the quality of the soap supplied from the soap supply port 43 (soap state: fluffy feeling, muddy feeling, etc.) ) Can be adjusted. In this way, based on the information on the liquid level P20 detected by the liquid level detecting means 7 (the liquid level liquid level height H1), the replenisher solution is supplied from the replenisher solution tank 81 via the soap state adjusting means 8B. By replenishing the container 40, the liquid level height H1 of the liquid level P20 can be adjusted according to the user's preference. Therefore, the movement distance H3 of the soap layer P10 is adjusted, and the liquid layer or temperature of the soap bubble P1 supplied from the soap supply port 43 can be adjusted. Further, by automatically controlling the liquid level detecting means 7 and the soap state adjusting means 8B via the control means 6B, the state (tactile feeling) of the soap can be freely adjusted. Further, as shown in FIG. 5, a user controller 6B1 operated by the user is provided, and the user can control the control means 6B via the user controller 6B1, thereby the liquid level of the liquid level P20. H1 can be adjusted.

  Moreover, it is preferable to set it as liquid: gas = 4: 6-1: 9 contained in the soap bubble P1 produced | generated with the soap generator of the present Example. However, the present invention is not limited to this. A more natural bathing sensation can be obtained by the ratio of the amount of liquid (water) and gas (air) in the soap aggregate P10 formed by the fine bubbles. That is, if the ratio of the liquid is adjusted to be high, a fluid feeling like a liquid can be given to the user. Further, if the air ratio is adjusted to be high, a fluffy tactile sensation can be given to the user. Therefore, the user can enjoy the soap bubble P1 with the tactile feeling he / she likes.
