  • the bubble generation device includes: a mixing part that mixes flush water with air to produce bubble water; and a water flowing part formed on the downstream side of the mixing part and including a detergent port through which detergent is injected into bubble water.
  • the water flowing part further includes an overflow port communicating with the outside of the water flowing part.
  • the present invention facilitates efficient production of bubble water and prevention of backflow of bubble water to a water supply pipe.
  • Fig. 1 is a front perspective view of a flush toilet 100.
  • a toilet bowl part 106 is formed in a toilet body 108 of the flush toilet 100. Also, in the toilet body 108, a water discharge pipe 110 is embedded. Flush water supplied from a water supply pipe to the toilet body is provided via the water discharge pipe 110 to a first discharge port 102 and a second discharge port 104. Through the first discharge port 102 and the second discharge port 104, flush water is discharged into the toilet bowl part 106. To the toilet body 108, a functional unit (an electrical component), not illustrated, such as a pubic lavage device, to be mounted on the toilet body 108 is added, so that a "toilet device" is configured. The entire or part of the toilet device may be housed in a cabinet installed around the flush toilet 100. The flush tank of the toilet device may be provided externally with respect to the toilet body 108, or may be embedded in a wall.
  • a bubble generation device 112 is mounted on the toilet body 108. Being “mounted on” here includes being “embedded in”.
  • the bubble generation device 112 receives tap water as flush water via a water supply pipe 114. Also, into the bubble generation device 112, air and detergent is injected (which will be detailed later).
  • the bubble generation device 112 mixes the flush water, air, and detergent to produce detergent bubble water, and supplies the detergent bubble water to the second discharge port 104. Through the second discharge port 104, a mixture of the flush water supplied through the water discharge pipe 110 and the detergent bubble water supplied from the bubble generation device 112 may be discharged, or one of the flush water and the detergent bubble water may be selectively discharged.
  • the bubble generation device 112 may supply the detergent bubble water to both the first discharge port 102 and the second discharge port 104.
  • the bubble generation device 112 in the present embodiment has a structure for performing two-step processes of mixing flush water and air to produce bubble water, and then mixing the bubble water with detergent to produce detergent bubble water.
  • the bubble generation device 112 of the present embodiment will be described as a device for producing detergent bubble water, the bubble generation device 112 may be configured as a device for supplying bubble water containing no detergent.
  • Fig. 2 is a sectional side view of the bubble generation device 112.
  • the downward direction in the drawing is the gravity direction (water flowing down direction).
  • the bubble generation device 112 is configured as a single unit, in which an ejector 116 (a mixing part), a water flowing part 126, and a shear part 128 are formed within a casing 138.
  • the casing 138 includes a water supply port 118 through which flush water is provided from public water supply via the water supply pipe 114, an air inlet 120 through which air is naturally drawn in, a detergent port 122 through which detergent is introduced, and an overflow port 124.
  • the ejector 116 receives flush water and air through the water supply port 118 and the air inlet 120 and mixes the flush water and air to produce bubble water.
  • the bubble water then flows down through an outlet 140 (a bubble water inlet) toward the water flowing part 126.
  • the water flowing part 126 receives detergent and bubble water through the detergent port 122 and the outlet 140 and mixes the detergent and bubble water to produce detergent bubble water.
  • the shear part 128 shears bubbles in the detergent bubble water using an impeller 136 having multiple holes, so as to reduce and uniform the bubble size. Since fine and uniform bubbles of detergent bubble water have improved cushioning properties, splash of urine or the like can be prevented more easily. Also, since the adhesion with the inner wall surface of the toilet bowl part 106 is improved, the bubbles of the detergent bubble water are likely to remain, thereby improving the flushing capability.
  • the water flowing part 126 includes a preliminary part 130 and an agitation part 132.
  • projections 134 are formed on an inner wall surface of the agitation part 132.
  • the projections 134 are formed as spiral projections, such as screw grooves (which will be detailed later in association with Fig. 5A , for example).
  • the overflow port 124 is formed on an upper end part of the agitation part 132.
  • the preliminary part 130 is a space above the overflow port 124
  • the agitation part 132 is a space below the overflow port 124. Since the overflow port 124 is opened to the atmosphere, the preliminary part 130 is also a space opened to the atmosphere. It is also possible to define the agitation part 132 as a space in which the projections 134 are formed, and the preliminary part 130 as a space in which the projections 134 are not formed.
  • the height (margin M) of the preliminary part 130 is desirably set to 20 millimeters or greater.
  • the margin M in the present embodiment corresponds to a height difference between the overflow port 124 and the outlet 140. Namely, in the present embodiment, the overflow port 124 is formed 20 millimeters or more below the outlet 140.
  • the ejector 116 is a known component having a function to mix flush water and air to produce bubble water.
  • flush water can be supplied at a pressure of tap water.
  • flush water may be pumped into the water supply port 118 by a pump embedded in the flush toilet 100.
  • air inlet 120 air may be naturally drawn in, or air having a pressure higher than an atmospheric pressure may be sent into the air inlet 120 by a pump.
  • flush water with a higher pressure can be mixed with air more easily.
  • flush water with a sufficient pressure can be provided to the ejector 116, which can efficiently produce bubble water accordingly.
  • Fig. 3 is a sectional side view of the bubble generation device 112 when an overflow is occurring.
  • the detergent bubble water produced in the agitation part 132 is discharged through the shear part 128.
  • the agitation part 132 may be unable to hold the detergent bubble water.
  • the excess detergent bubble water will flow into the overflow port 124.
  • the overflow port 124 is connected to the toilet bowl part 106 or a sewage pipe, and the excess detergent bubble water is discharged through an overflow path 150.
  • the overflow path 150 may be formed as a pipe included in the bubble generation device 112.
  • Fig. 4 is a schematic diagram that shows a method for producing detergent bubble water in the agitation part 132.
  • detergent 142 is injected.
  • the outlet 140 is formed at a position such that bubble water 144 discharged through the outlet 140 gets contact with the projections 134.
  • the flowing of the bubble water 144 is partially limited by the projections 134, so that multiple turbulent flows (vortexes) are generated within the bubble water 144.
  • the detergent 142 injected through the detergent port 122 has high viscosity, the detergent 142 slowly flows down along the projections 134 on the wall surface of the agitation part 132.
  • the bubble water 144 flowing while hitting on the projections 134 entrains the detergent 142 flowing along the surfaces of the projections 134, so that the bubble water 144 is mixed with the detergent 142, and detergent bubble water is produced.
  • Turbulent flows are generated within the bubble water 144. Accordingly, the turbulent flows of the bubble water 144 entrain the detergent 142 flowing along the surfaces of the projections 134, so that the bubble water 144 and the detergent 142 can be efficiently mixed.
  • the inner wall surface area of the agitation part 132 is enlarged.
  • the contact area between the detergent 142 and the bubble water 144 is also enlarged.
  • the time from when the detergent 142 enters the agitation part 132 until the detergent 142 is discharged therefrom can be increased. Accordingly, the detergent 142 can be dissolved in the bubble water 144 more easily.
  • the detergent port 122 is formed on an upper end part of the agitation part 132, the possibility of the bubble water 144 and the detergent 142 being mixed in the preliminary part 130, besides in the agitation part 132, is not zero. However, since most of the detergent 142 enters the agitation part 132, detergent bubble water is substantially, or mostly, produced within the agitation part 132.
  • the detergent 142 may be provided to the detergent port 122 by allowing the detergent 142 to naturally flow down or by pumping the detergent 142 with a pump.
  • Fig. 5A is a schematic diagram that shows the agitation part 132 in which spiral projections 134 are formed by integral molding.
  • Fig. 5B is a schematic diagram that shows the agitation part 132 in which a coil spring is provided to form spiral projections 134.
  • the projections 134 can be considered, such as a plate shape and a hook shape.
  • the projections 134 of the present embodiment are spirally formed on the inner wall surface of the agitation part 132. As shown in Fig. 5A , the spiral projections 134 may be formed as screw grooves on the inner wall of the agitation part 132 by integral molding. Alternatively, the spiral projections 134 may be additionally formed by providing a coil spring 146 in the agitation part 132, as shown in Fig. 5B .
  • Fig. 6 is a side view of the shear part 128.
  • the impeller 136 In the shear part 128 is provided the impeller 136 of which an axial direction is the water flowing direction, and the impeller 136 is rotated by the flowing of detergent bubble water.
  • the impeller 136 includes multiple blades, which each have multiple small holes formed therein. Accordingly, large bubbles in detergent bubble water are fragmented by the impeller 136. Small bubbles can pass through the small holes of the blades. Namely, the impeller 136 also functions as a sieve for bubbles.
  • a motor may be attached to the shaft of the impeller 136 to adjust the rotational speed of the impeller 136. By adjusting the rotational speed of the impeller 136, the bubble size can also be adjusted.
  • the rotational speed of the impeller 136 can be adjusted also by adjusting the relative positions of the outlet 140 and the impeller 136. For example, compared to the case where bubble water flows down to a position of which the distance from the shaft of the impeller 136 is R1, the rotational speed of the impeller 136 becomes lower because of a smaller moment when bubble water flows down to a position of which the distance from the shaft is R2 smaller than R1, i.e., a position closer to the shaft.
  • the flush toilet 100 particularly the structure of the bubble generation device 112 mounted on the flush toilet 100 has been mainly described based on an embodiment.
  • the ejector 116 is merely a component for mixing tap water and air, a conventional component can be often used as it is.
  • the bubble generation device 112 collectively includes, within the single casing 138, the ejector 116 for mixing water and air, the water flowing part 126 for mixing bubble water with detergent, and the shear part 128 for adjusting the bubble size of detergent bubble water, the bubble generation device 112 itself can be configured as a single component. Therefore, the bubble generation device 112 can be miniaturized more easily.
  • the structure of the bubble generation device 112 is simple, so that, as a component, the reliability can be maintained more easily.
  • spiral projections 134 are formed on the inner wall surface of the agitation part 132, the mixing of bubble water and detergent can be promoted.
  • the detergent port 122 opens on the preliminary part 130 in the present embodiment, the detergent port 122 may open on the agitation part 132. Also, the detergent port 122 may open on both the preliminary part 130 and the agitation part 132. Similarly, the overflow port 124 may be formed at two or more positions. Also in this case, it is desirable to provide a margin of 20 millimeters or more between the overflow port 124 at the highest position and the outlet 140.
  • a bubble generation device in an embodiment of the present invention includes: a mixing part that produces bubble water; and a water flowing part formed on the downstream side of the mixing part.
  • the water flowing part further includes an overflow port communicating with the outside of the water flowing part.
