  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The disposer 1 of the present invention includes a disposer tank 2 for crushing the stored garbage, a tank water supply path 4 configured to feed the tank water only to the disposer tank 2 with the outlet 4a facing the disposer tank 2, and A fine bubble generating device 5 for generating fine bubbles in the tank water discharged from the outlet 4a of the tank water supply path 4 into the disposer tank 2 is provided. As shown in FIG. 1B, the disposer tank 2 is formed in a bottomed cylindrical shape that can be opened upward, and an inlet of the drainage path 8 of the disposer 1 is opened at the bottom, and the inlet of the drainage path 8 is formed. The crushing part 10 which crushes the garbage accommodated in the disposer tank 2 is provided in the upper part. The crushing part 10 has a movable blade 10a that is rotationally driven by a motor 10b. Further, the disposer 1 is provided with a control unit 9 for controlling the water supply to the disposer tank 2 for tank water, the drive control of the crushing section 10, the operation of the fine bubble generator 5 and the like.

  As shown in FIG. 1A, the disposer 1 of the present example is located above the disposer tank 2 in the drainage hole 3a of the sink 3 in the middle of the drainage path 3b of the sink 3 that opens upward to the upper counter 6a of the kitchen cabinet 6. The disposer tank 2 is disposed so as to open the opening. Specifically, a sink lower space 7 that can be used as a storage space or a piping space is provided below the sink 3 of the cabinet 6, and the disposer 1 is disposed in the sink lower space 7. The tank water supply path 4 is drawn from the building to the disposer tank 2 in the space under the sink 7, and the fine bubble generating device 5 is disposed in the tank water supply path 4 in the space under the sink 7. ing. The tank water supply path 4 may be branched from the sink water supply path for supplying water to the currant 3 c of the sink 3. A water supply valve 14 for performing water supply control of the tank water by the control unit 9 is disposed in the tank water supply path 4.

  As shown in FIG. 2, the fine bubble generating device 5 of this example includes a gas mixing unit 15 that obtains gas mixed water by mixing gas into water flowing through the tank water supply path 4 from the upstream side of the tank water supply path 4. , A pump 16 that pumps water to the tank water supply path 4, a dissolution tank 17 a that constitutes a dissolution part 17 that dissolves bubbles in the gas-mixed water in water under a high-pressure environment to obtain gas-dissolved water, The fine bubble generating nozzle 18a that constitutes the precipitation portion 18 that precipitates the gas and generates fine bubbles to obtain water containing fine bubbles is sequentially provided.

  Although the forced mixing mechanism which pumps gas to water with an air pump can also be employ | adopted for the gas mixing part 15, in this example, since power is not especially required, the structure can be simplified and the tank water supply path 4 can be achieved. Ejector mechanism that naturally draws gas into the water that flows through the ejector effect is adopted. Specifically, it is configured by connecting a gas supply flow path 19 that opens to the room to a negative pressure generating part formed by providing a throttle part in the tank water supply path 4 so that indoor air can be mixed into water. Yes. Here, the gas supply flow path 19 is provided with a check valve (not shown) for preventing the backflow of water and a gas mixing amount adjusting valve 12 constituting the gas mixing amount adjusting means 11.

As shown in FIG. 3A, the gas mixing amount adjustment valve 12 has a cylindrical main body portion 12a in which the internal flow passage is communicated with the gas supply flow passage 19, and an inner peripheral wall of the internal flow passage of the main body portion 12a. A movable valve body 12b disposed in the main body portion 12a by screwing the outer peripheral portion, and the main body portion 12a and the movable valve body 12b by screwing the movable valve body 12b into the internal flow path of the main body portion 12a. The amount of gas mixed into the tank water by the gas mixing unit 15 can be adjusted. In the figure, 12a ₁ is a female screw portion provided in the main body portion 12a, and 12b ₁ is a male screw portion provided in the movable valve body 12b. The movable valve body 12b is driven to rotate by a motor (not shown) controlled by the control unit 9, that is, the control unit 9 can control the amount of gas taken into the tank water. For example, if the amount of gas mixed into the tank water is made small by the gas mixing amount adjusting means 11, the void ratio (ratio of gas occupying the space) in the dissolution tank 17a can be suppressed, and the gas can be efficiently liquefied. It can be dissolved in the inside, and the density of the generated fine bubbles can be reduced and the bubble diameter of the fine bubbles can be kept small. The diameter can be adjusted. In particular, when the volume ratio of the intake gas amount to the tank water is set to 0.1 to 10%, it is preferable because the burden on the pump 16 through which the gas-mixed water passes can be suppressed.

  The dissolution tank 17a is divided into a primary tank 20 (a bubbling tank) and a secondary tank 21 (a water level detection tank) by a partition wall 22 as shown in FIG. The side tank 21 has a structure in which the gas circulation part 23 at the upper part of the partition wall 22 and the water passage part 24 at the lower part of the partition wall 22 communicate with each other. The upstream tank water supply path 4 is connected to the upper part of the primary tank 20 and a spray nozzle 25 is arranged. The downstream tank water supply path 4 is connected to the bottom of the secondary tank 21 and the tank discharge port. 26 is disposed, and an air vent valve 27 is provided on the side wall of the secondary tank 21. In the primary side tank 20, the gas mixed water pumped by the pump 16 is jetted at a high speed by the spray nozzle 25 to be bubbled in the tank, and the gas is dissolved in water under a high pressure environment by the pump 16. The secondary tank 21 is a tank for obtaining gas-dissolved water. The secondary tank 21 raises bubbles that could not be dissolved up to the tank outlet 26 to the gas recirculation part 23, and removed excess gas by the air vent valve 27. It is a tank for stabilizing the water level in 17a and achieving stable operation of the dissolution tank 17a.

  Further, as shown in FIG. 3C, the fine bubble generating nozzle 18 a includes a nozzle inlet 28 from the upstream side of the tank water supply path 4, a small diameter path 29 communicating radially from the nozzle inlet 28, and a vortex portion communicating with the small diameter path 29. 30 and a nozzle outlet 31 communicating with the swirl portion 30 is provided in order. Here, in the small-diameter path 29, the pressure of the flowing water is drastically decreased, the decompression boiling starts in the dissolved gas of the dissolved gas water, and the gas is precipitated from the dissolved gas as fine bubbles having a bubble diameter of 0.1 to 1000 μm. Have That is, the precipitation part 18 is substantially constituted by the small diameter path 29. Further, the vortex section 30 has a function of generating a vortex flow of water inside and flowing only uniform fine bubbles having a relatively small bubble diameter to the nozzle outlet 31. Specifically, a vortex as indicated by an arrow C is generated in the vortex section 30. Since the central portion of the vortex has a lower flow velocity than the outer peripheral portion of the vortex, the pressure is reduced, and bubbles having a large diameter are formed in the central portion of the vortex due to collision of fine bubbles generated in the small diameter path 29. Since the shear force acts on the vortex due to the velocity gradient generated in the radial direction of the vortex, when a large bubble at the center of the vortex moves to the outer periphery of the vortex by centrifugal force, it is divided by the vortex shear force. It turns into a small bubble. The outer periphery of the vortex is preferentially discharged to the nozzle outlet 31 by the centrifugal force due to the rotation of the vortex as indicated by the arrow D, but the predetermined diameter from which bubbles having a large diameter are removed as described above. Since the following microbubbles are present, microbubbles having a predetermined diameter or less are continuously discharged from the outer periphery of the vortex together with water. That is, according to this eddy current portion 30, it is possible to eliminate bubbles whose bubble diameter has increased due to some cause after the generation of fine bubbles, and homogeneous microbubbles composed only of fine bubbles with a bubble diameter of 0.1 to 1000 μm. It is possible to obtain the contained water stably. The size of the fine bubbles discharged through the vortex section 30 is determined by the angular velocity of the vortex of the vortex section 30, and smaller bubbles can be discharged as the angular velocity increases, and the vortex angular velocity flows into the vortex section 30. Since it is variable according to the flow velocity to be generated, fine bubbles having a desired bubble diameter can be generated by changing the flow velocity of the flow into the vortex section 30.

  Here, in the disposer 1 of this example, the fine bubble generating nozzle 18 a is provided at the outlet 4 a of the tank water supply path 4. Accordingly, the tank water containing the fine bubbles immediately after the precipitation can be discharged into the disposer tank 2 from the outlet 4a of the tank water supply path 4. In other words, the water for the tank in which the fine bubbles having a small bubble diameter as small as possible before the large number of generated fine bubbles are combined to increase the bubble diameter are discharged into the disposer tank 2 from the outlet 4a of the tank water supply passage 4. It is possible to make it contain.

  In the disposer 1 of this example, the cleaning effect of the fine bubbles generated by the fine bubble generator 5 can be applied to the disposer tank 2 which has been one cause of bad odor in the kitchen. The inside of 2 can be kept clean and it is possible to suppress the generation of malodor. Of course, in the drainage path 8 through which the tank water is drained, it is possible to suppress the generation of bad odor by acting the cleaning effect of the fine bubbles. In other words, although the waste litter crushed by the crushing unit 10 adheres to and remains on the inner surface of the disposer tank 2, a bad odor is generated from the disposer tank 2. Due to the cleaning effect of the removal effect, it was possible to peel off garbage debris adhering to the inner surface of the disposer tank 2 and flow it to the drainage path 8 to remove it. It is possible to suppress this. Specifically, a large amount of microbubbles spreads in the tank water and collides efficiently with garbage debris attached to the inner surface of the disposer tank 2 to rupture the soil, or a large amount of microbubbles collapse Garbage debris is peeled off from the inner surface of the disposer tank 2 by a large amount of ultrasonic waves generated from time to time, or adsorbed to the garbage debris by the adsorption characteristics (Marangoni effect, etc.) of the microbubble interface and peeled from the inner surface of the disposer tank 2 It is adsorbed to suspended substances (garbage debris after peeling) and floated and separated, or the surface of the microbubbles is negatively charged and electrostatically adsorbed to the suspended substances to make the suspended substances fine bubbles. Therefore, an effective cleaning effect can be imparted to the disposer tank 2. Further, the frictional resistance is reduced due to the inclusion of fine bubbles, so that the effect of preventing water splashing and the effect of silence of the cleaning sound can be obtained. In addition, since the microbubbles are contained in the tank water, the apparent bulk specific gravity of the tank water is reduced, so that a water saving effect can be obtained.

  In addition, the outlet 4 a of the tank water supply path 4 of the disposer 1 of this example is provided in the upper part of the inner surface of the disposer tank 2 so that the opening direction is along the inner surface of the disposer tank 2. The tank water discharged from the outlet 4a can flow down along the inner surface of the disposer tank 2 (arrow A), and the cleaning effect by the fine bubbles can be exhibited on the inner surface of the disposer tank 2 without any problems. ing. Moreover, according to the fine bubble generating apparatus 5 of this example, since the gas is once dissolved in the tank water and then precipitated to generate the fine bubbles, the tank containing only the fine bubbles having a bubble diameter of 0.1 to 1000 μm. Water can be obtained stably. Since the fine bubbles having a bubble diameter of 0.1 to 1000 μm can be diffused in the tank water and can stay in the tank water for a long time, the cleaning effect of the fine bubbles is exerted in the disposer tank 2 and the drainage path 8. It was able to act effectively. In general, the drainage path 8 is provided with a drainage trap that is sealed with stored water. However, since the stored water can be constituted by tank water containing fine bubbles, the drainage trap that is likely to be attached to garbage debris is cleaned. There is also an advantage that clogging can be prevented. It is preferable to adjust the gas mixing amount adjusting means 11 or the like so that only fine bubbles having a bubble diameter of 0.1 to 200 μm are included in the tank water in the fine bubble generator 5. The cleaning effect can be obtained more effectively. Furthermore, if only the fine bubbles with a bubble diameter of 0.1 to 1 μm are included, the fine bubbles with the above 0.1 to 1.0 μm have a very long residence time in the tank water, so that the above cleaning effect is obtained. Can be obtained continuously.

  Further, according to the gas mixing amount adjusting means 11, mixing of gas into the tank water can be stopped, that is, the water containing fine bubbles and the water not containing fine bubbles can be switched as the tank water. However, the gas mixing amount adjusting unit 11 can also function as a bubble presence / absence switching unit that switches between water containing fine bubbles and water not containing fine bubbles. The tank water that does not contain fine bubbles has a higher frictional resistance against the inner surface of the disposer tank 2 than the tank water that contains fine bubbles, that is, the tank water that does not contain fine bubbles contains a fine bubble. Compared to irrigation water, the impact on the inner surface of the disposer tank 2 is large, and therefore, it is suitable for washing away the detergent bubbles adhering to the inner surface of the disposer tank 2. The disposer tank 2 is disposed in the drainage path 3b of the sink 3 as in the case of the disposer 1 of this example, and the detergent foam of the detergent used in the dishwashing performed in the sink 3 is the drainage of the sink water (arrow B ), It is useful that the gas mixing amount adjusting means 11 does not contain fine bubbles in the tank water when it is assumed to adhere to the inner surface of the disposer tank 2.

  FIG. 4 shows another example of the embodiment. The same parts as those in the previous example are denoted by the same reference numerals and description thereof is omitted. In this example, the melting portion 17 is constituted by a melting tube 17b instead of the melting tank 17a of FIG. 2 or FIG. The melting tube 17b can be constituted by, for example, a bellows tube in which a continuous resistor 33 for suddenly changing the pressure and flow velocity is provided on the inner surface. The bellows tube is formed by continuously forming an annular recess 33a having an arc cross section in the axial direction of the melting tube 17b, and a connecting portion between adjacent annular recesses 33a becomes an annular projection 33b protruding into the melting tube 17b. Yes. That is, the melting tube 17b has the smallest diameter at the annular convex portion 33b and the largest diameter at the bottom portion of the annular concave portion 33a, and the diameter gradually changes during that time. When the gas-mixed water pressurized by the pump 16 flows into the tubular body provided with the resistor 33 continuously on the inner surface, the gas-liquid mixed water is greatly disturbed locally by the continuous resistor 33 one after another. The mixture is stirred and mixed in the pressurized state after passing. In this case, in the melting tube 17b formed of a bellows tube, as shown by an arrow E in FIG. 4B, the inner surface of the melting tube 17b hits the continuous annular convex portion 33b and turns along the inner surface of the annular concave portion 33a. It is disturbed, and this disturbance is performed one after another over the entire inner circumference of the dissolution tube 17b. Furthermore, as shown in FIG. 4 (c), since the annular convex portion 33b portion has the smallest diameter in the melting tube 17b, the portion including the annular convex portion 33b portion has a high flow velocity and a small pressure, Since the bottom portion of the annular recess 33a has the largest diameter, the portion including the bottom portion of the annular recess 33a has a slow flow rate and a large pressure, whereby the gas-liquid mixed water passing through the dissolution tube 17b has a flow rate and pressure. The sudden change is repeated continuously. Due to these actions, the gas-mixed water is continuously stirred and mixed as it passes through the dissolution tube 17b, and the dissolution of the gas in the gas-mixed water into the water is greatly promoted. Further, when the gas mixture water swirls and disturbs the annular recess 33a of the dissolution tube 17b, the dissolution of the gas in water is promoted as described above. In this case, the undissolved gas that has not been dissolved 34 accumulates at the bottom of the annular recess 33a. That is, the bottom of the annular recess 33a becomes a minute gas reservoir in which the undissolved gas 34 is accumulated. Then, water flowing while swirling the annular recess 33a comes into contact with a gas reservoir formed in a pressurized state, and the undissolved gas 34 is effectively dissolved in water at the interface. This is the same function as that of the previous dissolution tank 17a, and even though the dissolution tube 17b is formed of a tubular body, it is possible to obtain gas dissolution water that effectively dissolves gas in water. Thus, the miniaturized bubble generator 5 can be miniaturized. The melting tube 7b can also be configured by a bellows-like flexible hose. In addition, in the fine bubble generating apparatus 5 that obtains fine bubbles by decompressing the gas as shown in FIGS. 1 to 4 and then reducing the pressure, it is possible to generate extremely fine and highly uniform fine bubbles. Has advantages.

  FIG. 5 shows still another example of the embodiment. The fine bubble generating device 5 of this example is accompanied by pressure fluctuation with respect to the bubbles mixed in the water in the tank water supply path 4 in the gas mixing section 15 by the pressure sudden change section 36 provided in the tank water supply path 4. Fine bubbles are generated by miniaturization by applying a shearing force. The sudden pressure change part 36 of this example is constituted by a pressure reducing / pressurizing means 37. For example, a Venturi tube 38 can be used as the pressure reducing / pressurizing means 37. In the pressure reducing / pressurizing means 37, when the bubbles pass through the throat portion, the flow velocity is increased and the pressure is reduced and expanded, and thereafter the cross-sectional area is increased. The pressure increases and shrinks as it increases, but the bubbles are crushed by the shearing force generated at this time, so that fine bubbles with a bubble diameter of 0.1 to 1000 μm are obtained. In addition, it is preferable to dispose the mesh in the tank water supply path 4 downstream from the decompression / pressurization means 37 and to pass the water containing fine bubbles through the mesh because the diameter of the fine bubbles can be further subdivided. . Further, the vortex section 30 may be provided downstream of the pressure reducing / pressurizing means 37, and relatively homogeneous water containing fine bubbles including fine bubbles having a predetermined diameter or less can be obtained in the vortex section 30.

  FIG. 6 shows still another example of the embodiment. The fine bubble generating apparatus 5 of the present example is provided with the pressure suddenly changing portion 36 at multiple stages in the tank water supply path 4 to configure the bubble refinement process in multiple stages to achieve more efficient and advanced microbubble formation. Yes. Specifically, in this example, the pressure reducing / pressurizing means 37a and 37b as the pressure suddenly changing portion 36 are formed in two stages on the upstream side and the downstream side of the tank water supply path 4, and shear force bubbles due to pressure fluctuations are formed. On the other hand, the generation of fine bubbles having a smaller bubble diameter is achieved by acting in two stages. Specifically, the upstream pressure reducing / pressurizing means 37a is provided with one venturi pipe 38 as a part of the tank water supply path 4 (main flow path 4a). The downstream decompression / pressurization means 37b branches the downstream side of the tank water supply path 4 from the portion where the upstream decompression / pressurization means 37a is provided into a plurality of branch channels 4b. Are each provided with a venturi tube 38. More specifically, the downstream venturi tube 38 is formed according to the diameter of the fine bubbles to be generated so as to be 1/2 the diameter of the upstream venturi tube 38 and the cross-sectional area is 1/4. Four passages 4b are formed, and each branch flow path 4b is provided with a venturi tube 38. The total cross-sectional area of the downstream venturi tube 38 is equal to the cross-sectional area of the upstream venturi tube 38. When the generated fine bubbles are concentrated at one place, they are connected to become larger bubbles, and in this example, they branch into a plurality of branch flow paths 4b and are downstream of each branch flow path 4b. In other words, it has been devised to suppress the generation of large bubbles by colliding a large number of fine bubbles at one location and making it possible to stably obtain fine bubbles of a predetermined diameter. ing.

  By the way, in the case of a device in which the fine bubble generating device 5 generates fine bubbles by making the fine bubble generating device 5 fine by applying a shearing force to the bubbles in the gas-mixed water, as in the examples of FIGS. Compared with the fine bubble generating device 5 that once converts the gas-mixed water into gas-dissolved water as in 1 to 4 and then generates fine bubbles by precipitation to obtain fine bubble-containing water, the device can be simplified and the size can be reduced. In addition, since a large power source is not required, the simplification and miniaturization of the apparatus can be facilitated as the microbubble generator 5 that uses the water pressure without the pump 16 as in the example of FIG. It can also be made. Moreover, the gas mixing part 15 can also be provided in the tank water supply path 4 downstream of the pump 16 as shown in FIG.

  FIG. 9 shows still another example of the embodiment. This example is another example of the fine bubble generating device 5 that generates fine bubbles by applying a shearing force to bubbles in the gas-containing water as in the previous example, and the fine bubble generating device 5 is a gas. This is an example constituted by gas-liquid shear layer generating means 35 for forming a gas-liquid shear layer in the mixed water. The gas-liquid shear layer generating means 35 of this example is configured by means for generating a jet stream that has a remarkably fast flow velocity in the gas mixture water by, for example, constricting the tank water supply path 4, and mixing the gas in the jet stream A shear force is generated at the gas-liquid interface in the water (so-called gas-liquid interface becomes a gas-liquid shear layer), and the bubbles are refined by the shear force to obtain fine bubbles. Specifically, in this example, the water flowing through the tank water supply path 4 at the gas introduction part of the gas mixing unit 15 is a jet stream, and the gas between the bubbles and water is different due to the difference in speed between the mixed bubbles and water. The liquid boundary surface becomes a so-called gas-liquid shear layer, and a shearing force is applied to the bubbles so that the bubbles are refined to obtain fine bubbles.

  FIG. 10 shows still another example of the embodiment. This example is an example in which the fine bubble generating device 5 is configured by the gas-liquid shear layer generating means 35 for forming a gas-liquid shear layer in the gas mixture water as in the previous example. The gas-liquid shear layer generating means 35 of this example uses the same structure as the fine bubble generating nozzle 18a described above, that is, a small-diameter path in which the channel width of the tank water supply path 4 through which the gas mixture water flows is extremely narrowed. 29 and a vortex section 30 that generates a swirling flow inside the small-diameter path 29 continuously. That is, in the gas mixture water passing through the small-diameter path 29, a shear force is generated at the boundary surface between bubbles and water due to the velocity gradient in the cross-sectional direction (so-called gas-liquid boundary surface becomes a gas-liquid shear layer). Then, the bubbles are made finer, and the vortex generated in the vortex section 30 also generates a shearing force at the boundary between the bubbles and water due to the velocity gradient inside and outside the vortex (so-called gas-liquid interface is This becomes a gas-liquid shear layer), and the bubbles are refined by this shearing force to obtain fine bubbles. The gas-liquid shear layer generating means 35 can be configured by at least one of the small-diameter path 29 or the vortex section 30.

  Here, FIG. 11 shows still another example of the embodiment as a modification of the example of FIG. This example is an example in which the bubble diameter of the fine bubbles generated by making the flow path width of the small diameter path 29 in FIG. 10 variable is adjustable, that is, an example in which the bubble diameter adjusting means 13 is provided. Specifically, in the fine bubble generating device 5 of this example, the protrusion 53 is directed toward the axial center direction on the inner surface portion of the hollow cylindrical fixing member 52 whose axial direction is the flow direction of the tank water supply passage 4. Are protruded, and leg portions 54 are protruded toward the axial center direction at predetermined intervals in the circumferential direction on the inner surface portion of the fixing member 52 on the downstream side of the tank water supply path 4 from the protrusion 53. A threaded portion 55b engraved on the peripheral surface of a cylindrical movable member 55 whose axial direction is the flow direction of the tank water supply path 4 is screwed into a threaded portion 54a engraved at the protruding tip of the leg portion 54 to axially move. The downstream end surface 53a of the projecting portion 53 and the upstream end surface 55a of the movable member 55, which are disposed at the downstream side of the projecting portion 53 inside the fixed member 52 so as to be freely screwable to each other. Is made variable by the screwing of the movable member 55 in the axial direction. , I.e. channel width of the small-diameter path 29 is variable. The movable member 55 is rotationally controlled by a motor (not shown) controlled by the control unit 9, that is, the control unit 9 can control the size of the bubble diameter of the fine bubbles generated in the tank water. . For example, if the flow path width of the small-diameter path 29 is reduced, the velocity gradient in the cross-sectional direction of the gas mixed water flowing through the small-diameter path 29 is increased, and the shear force acting on the bubbles of the gas mixed water is increased. The formation of fine bubbles having a relatively small bubble diameter can be generated. On the contrary, when the flow path width of the small diameter passage 29 is increased, fine bubbles having a relatively large bubble diameter can be generated for the reason opposite to the above. In addition, the fine bubble-containing water containing the fine bubbles whose bubble diameter is uniformly adjusted by the bubble diameter adjusting means 13 before the fine bubbles are united and become larger or non-uniform, It is preferable to use it as water discharge as it is. That is, the bubble diameter adjusting means 13 is preferably provided in the vicinity of the outlet 4 a of the tank water supply path 4 facing the disposer tank 2. According to the fine bubble generating device 5 of FIGS. 9 to 11, since the pressure loss in the device 5 can be reduced as compared with, for example, the fine bubble generating device 5 that obtains fine bubbles in the pressure sudden change portion 36 of the previous example, It has an advantage that it can be applied to a lower pressure environment.

  FIG. 12 shows still another example of the embodiment. In this example, the fine bubble generating device 5 is disposed in a gas mixing portion 15 for obtaining gas mixed water by mixing a gas into water flowing in the tank water supply path 4 and a tank water supply path 4 in which the gas mixed water flows. The ultrasonic vibrator 39 is configured to cause ultrasonic vibration to act on the gas-mixed water and shear the bubbles in the standing wave region so as to obtain fine bubbles. ing. This fine bubble generating device 5 has the advantage that almost no pressure loss is generated in the device 5, and further, the bubble diameter of the fine bubbles is changed by changing the frequency of the ultrasonic wave generated by the ultrasonic vibrator 39. (That is, the ultrasonic frequency adjusting means generated by the ultrasonic transducer 39 constitutes the fine bubble diameter adjusting means 13 controlled by the control unit 9).

  FIG. 13 shows still another example of the embodiment. This example is an example in which gas useful component mixing means 43 whose operation is controlled by the control unit 9 is provided in the tank water supply path 4. Specifically, in this example, a high voltage discharge unit 40 that generates ozone is provided in the middle of the gas supply channel 19 of the gas mixing unit 15. That is, since the gas mixed in the water can be constituted by ozone, the fine bubbles containing ozone are obtained by generating fine bubbles of ozone through the fine bubble generating device 5, and the fine bubbles containing ozone are obtained. Tank water made of contained water can be supplied into the disposer tank 2. Here, since ozone has a strong oxidizing power, it has a high bactericidal effect and an organic matter decomposing effect. The fine bubbles generated by the fine bubble generator 5 can be dispersed without having to immediately come out of the water due to the high specific surface area and internal pressure as described above. And contact efficiency between the bubble interface Thus, the synergistic effect of both can dramatically improve the dirt removal effect in the disposer tank 2 (and the drainage path 8), and even in a small amount of ozone, the disposer tank 2 (and the drainage path 8) On the other hand, the dirt removal effect can be exhibited. In addition to being effective for sterilizing the inner surface of the disposer tank 2, the microbubble-containing water containing ozone is stored as stored water in the drainage path 8 where the germs are likely to be generated and the trap part of the drainage path 8. The sterilization / antibacterial effect of the water itself and the inner surface of the drainage channel 8 can be effectively obtained, and the effect of removing dirt, urine stones and slime, and the effect of preventing the adhesion of dirt can be effectively enhanced. Further, as in this example, the ozone generated in the high voltage discharge unit 40 can be made permanently because the gas passing through the gas supply flow path 19 is used as a raw material, that is, maintenance such as replacement work is unnecessary and good. It has excellent usability.

  Further, as the gas useful component mixing means 43, as shown in FIG. 14, an oxygen supply unit 42 that increases the oxygen concentration of the gas mixed into the tank water is arranged in the middle of the gas supply channel 19 of the gas mixing unit 15. However, it is also preferable that the fragrance component supply unit 46 that includes the fragrance component in the gas mixed in the tank water is disposed in the middle of the gas supply channel 19 of the gas mixing unit 15. As the oxygen supply unit 42, an oxygen-enriched film 42a that can obtain oxygen-enriched air obtained by increasing the oxygen concentration of the gas flowing through the gas supply channel 19 to 25 to 40% can be employed. . According to the oxygen supply part 42, oxygen can be confined in the fine bubbles, oxygen can be supplied in the fine bubbles as much as the aerobic microorganisms for decomposing the garbage, and the function of the aerobic microorganisms can be activated. it can. According to the fragrance component supply unit 46, the fragrance component can be confined in the fine bubbles, and the fragrance component can be distributed throughout the disposer tank 2 together with the fine bubbles to generate the fragrance from the entire disposer tank 2. In addition, it is also preferable to mix a fragrance component in the oxygen-enriched air obtained by the oxygen supply unit 42.

  Further, as shown in FIG. 15, a hygroscopic part 41 in which silica gel or the like for dehumidifying gas is loaded in an upstream part of the gas supply flow path 19 from the high voltage discharge part 40 in order from the upstream side, the previous oxygen supply part 42 is also preferable. According to this, the gas dehumidified by the moisture absorption part 41 can be introduced into the high voltage discharge part 40, and the generation efficiency of ozone in the high voltage discharge part 40 can be improved. Further, the oxygen enrichment film 42a can increase the oxygen concentration of the gas, and the ozone generation efficiency in the high voltage discharge unit 40 can be improved. Thus, by increasing the ozone generation efficiency in the high-voltage discharge section 40, the ozone concentration of the fine bubble-containing water can be increased to further enhance the sterilization effect of ozone. The sterilization / antibacterial effect on the inner surface can be further enhanced.

  FIG. 16 shows still another example of the embodiment. This example is an example in which liquid useful component mixing means 44 whose operation is controlled by the control unit 9 is provided in the tank water supply path 4. The liquid useful component mixing means 44 includes a useful component storage tank 44 a filled with useful components and a useful component supply passage 44 b extending from the useful component storage tank 44 a to the tank water supply passage 4.

It can consist of valves. The useful component storage tank 44a may be detachably attached to the useful component supply passage 44b like a cartridge type so as to be replaceable. As the liquid useful component, a surfactant, an aromatic component and the like are preferable. Liquid useful components are likely to gather at the gas-liquid interface of the fine bubbles, and the fine bubbles are likely to adhere to the inner surface of the disposer tank 2 due to the adsorption effect of the gas-liquid interface. Thus, for example, when the useful liquid component is a surfactant, the concentrated surfactant collected at the gas-liquid interface of fine bubbles can be efficiently attached to the inner surface of the disposer tank 2, and Oil can be effectively removed from the inner surface. Further, according to the surfactant, even if the fine bubbles float on the water surface, it is difficult to rupture and disappear, so that the fine bubble layer can be formed on the water surface portion of the stored water in the trap portion of the drainage path 8 and the fine bubbles can be formed. The drainage path 8 can be sealed with the bubble layer, and the odor prevention effect of the drainage path 8 can be improved. Furthermore, the surface active agent can reduce the surface tension of the tank water and promote the refinement of bubbles by shearing force or the like. Moreover, when the liquid useful component is an aroma component, the concentrated aroma component gathered at the gas-liquid interface of fine bubbles is efficiently attached to the inner surface of the disposer tank 2 to generate aroma from the inner surface of the disposer tank 2. Can do.

  FIG. 17 shows still another example of the embodiment. This example is an example in which solid useful component mixing means 45 is provided in the tank water supply path 4. According to the solid useful component mixing means 45, the solid useful component can be dissolved in the tank water. The solid useful component dissolved in the tank water has the property of being collected at the gas-liquid interface of the fine bubbles in the same manner as the liquid useful component. Here, as the solid useful component, an aroma component or the like is preferable, and the concentrated aroma component gathered at the gas-liquid interface of fine bubbles is efficiently attached to the inner surface of the disposer tank 2 to generate aroma from the inner surface of the disposer tank 2. be able to. Each useful component mixing means 43, 44, 45 is preferably combined with various useful components and supplied to the tank water, or the useful component mixing means 43, 44, 45 may be used in combination. In addition, in the above example, ozone is used as a useful component for supplying bactericidal and antibacterial effects as a useful component to be supplied to tank water by each of the useful component mixing means 43, 44, 45, and a cleaning effect for specific substances such as oil is given. A useful component that imparts other functions not included in the above effects, such as activating aerobic microorganisms, a fragrance component (fragrance) as a useful component that imparts an effect to counteract malodor, a surfactant as a useful component As examples, oxygen is exemplified, but other useful components may be used as various useful components.

  FIG. 18 shows still another example of the embodiment. In this example, the nozzle flow at the outlet 4a of the tank water supply path 4 facing the disposer tank 2 can apply the tank water to a wide area of the disposer tank 2 so that the water discharge form is a shower flow. The water outlet is provided with a bubble diameter adjusting means 13 for adjusting the bubble diameter of the fine bubbles generated by the fine bubble generating device 5 to be contained in the discharged water at the outlet 4a of the tank water supply path 4. . Specifically, an opening area adjustment cover in which a large number of shower discharge holes 57b are formed in the outlet 4a of the water supply passage 4 for the tank where the water spray plate 56 having a large number of shower discharge holes 57a is disposed. 58 is attached to the water spray plate 56 so as to be freely rotatable. By rotating the opening area adjustment cover 58, the shower discharge hole 57a of the water spray plate 56 and the shower discharge hole 57b of the opening area adjustment cover 58 are connected. The size of the overlapping area (that is, the opening area of each shower discharge hole 57) can be changed. The opening area adjustment cover 58 is rotationally controlled by a motor (not shown) controlled by the control unit 9, that is, the control unit 9 can control the size of the bubble diameter of the fine bubbles generated in the tank water. Has been. For example, if the opening area of the shower discharge hole 57 is reduced, the width of the pressure fluctuation can be increased, the miniaturization of the fine bubbles can be promoted, and the bubble diameter of the fine bubbles can be adjusted small.

  As the bubble diameter adjusting means 13, the one shown in FIG. The bubble diameter adjusting means 13 of this example has an opening hole number adjusting cover 59 that allows the shower discharge hole 57 of the water spray plate 56 to be closed, and is attached to the outlet 4a of the tank water supply path 4 so as to be slidable in the circumferential direction. By sliding the hole number adjusting cover 59 in the circumferential direction, the numerous shower discharge holes 57 of the water spray plate 56 are gradually closed in the circumferential direction so that the size of the entire opening area of the shower discharge holes 57 can be changed. The opening hole number adjusting cover 59 is rotationally controlled by a motor (not shown) controlled by the control unit 9, that is, the control unit 9 can control the size of the bubble diameter of the fine bubbles generated in the tank water.
