[0029]
Next, the water soap introduction passage 130 and the water soap outflow passage 140 will be described.
A water soap introduction passage 130a is formed in the bellows lower support 60. A check valve 131 for water soap introduction is connected to the water soap introduction passage 130a. The check valve 131 for introducing water soap opens in the direction in which the water soap in the case chamber 20S is sucked, and closes with the pressure of the water soap in the opposite direction.
[0030]
In addition, the bellows upper support member 92 is formed with a water soap outflow passage 140a communicating with the lower outflow opening 82a of the water soap supply bellows 80. A check valve 141 for water soap outflow is connected to the water soap outflow passage 140a. The water soap outflow check passage 141 is connected to a water soap outflow soap passage 140b, connected to the water soap outflow soap passage 140c, and connected to the foam nozzle 150. The water soap outflow check valve 141 is opened by the pressure of the water soap from the water soap supply bellows 80 to the foam nozzle 150, and is closed by the pressure in the opposite direction.
[0031]
Next, the foam nozzle 150 will be described.
As shown in FIG. 5, the foam nozzle 150 is attached to a nozzle holder 44 formed on a side of the nozzle flange 40. The nozzle holder 44 has a nozzle holder recess 44a, and the end of the foam nozzle 150 is fitted into the nozzle holder recess 44a, and is fixed by a foam nozzle mounting screw 152. The foam nozzle 150 includes a nozzle mixing chamber 153a and a nozzle passage 150a communicating with the nozzle mixing chamber 153a. Each of the outflow openings of the water soap outflow passage 140 and the air outflow passage 120 is provided in the nozzle mixing chamber 153a. It is connected.
[0032]
The nozzle mixing chamber 153a connects the first introduction passage 153b, the first expansion chamber 153c having a larger flow area than the first introduction passage 153b, the connection passage 153d, and the second expansion chamber 153e, and also has a first introduction passage. A first mesh 153f is provided between the portion 153b and the first expansion chamber 153c, and a second mesh 153g is provided at an outflow opening of the second expansion chamber 153e.
[0033]
When water soap and air are pressure-fed to the first introduction passage portion 153b of the nozzle mixing chamber 153a having this configuration, the water soap is bubbled as air in the first stage, passes through the first mesh 153f, and passes through the first expansion chamber. 153c. At this time, when the water enters the first expansion chamber 153c from the first introduction passage 153b, the volume increases, so that the water soap is further foamed, and further, the connection passage 153d, the second expansion chamber 153e, and the second mesh. By passing through 153 g, the water soap is almost ideally foamed with air.
[0034]
Next, the discharging operation of the foam soap by the mousse dispenser 10 will be described.
It is assumed that the case chamber 20S in the case body 21 is filled with water soap, and the air supply bellows 70 and the water soap supply bellows 80 are in an extended state shown in the figure. At this time, air is filled in the air chamber 70S of the air supply bellows 70 via the outside air introduction passage 110 and the outside air introduction check valve 111, while water is filled in the water soap chamber 80S of the water soap supply bellows 80. It is assumed that the soap is filled.
[0035]
In this state, when the upper surface 98a of the cap 96 is manually pushed, the shaft 94, the check valve 141 for water soap outflow, the check valve 121 for air outflow, and the bellows upper support member 92 are united with the cap 96 downward. Then, the air supply bellows 70 and the water soap supply bellows 80 are simultaneously compressed.
[0036]
Thereby, the air in the air chamber 70S of the air supply bellows 70 is sent to the bubble nozzle 150 via the air outflow passage 120, that is, the air outflow passage 120b, the air outflow check valve 121, and the air outflow passage 120c. Can be At this time, since the outside air introduction passage 110 is provided with the outside air introduction check valve 111, the air of the air supply bellows 70 does not escape to the outside air.
[0037]
On the other hand, the water soap filled in the water soap chamber 80S by the compression of the water soap supply bellows 80 passes through the water soap outflow passage 140, that is, the water soap outflow soap passage 140a, the water soap outflow check valve 141, the water stone The foam nozzle 150 is reached via the outflow soap passage 140b, the waterstone outflow soap passage 140c, and the waterstone outflow soap passage 140d. Then, in the foam nozzle 150, the water soap is foamed with air to form foam soap, which is discharged from the nozzle port 150 </ b> N of the foam nozzle 150. The foamed soap discharged from the nozzle port 150N is used for hand washing and the like.
[0038]
Then, when the pressing force to the cap 96 is released, the air supply bellows 70 and the water soap supply bellows 80 try to return to the original state due to the restoring force of the air supply bellows 70 and the water soap supply bellows 80. At this time, the air supply bellows 70 sucks air into the air chamber 70S via the outside air introduction passage 110a and the outside air introduction check valve 111 because the inside of the air chamber 70S has a negative pressure. At the same time, the water soap supply bellows 80 suction-fills the water soap chamber 80S with the water soap through the water soap introduction check valve 131 by the negative pressure. This fills the air supply bellows 70 with air and fills the water soap supply bellows 80 with water soap, and enters a standby state for discharging foam soap.
[0039]
According to the mousse dispenser 10 according to the above embodiment, the following effects are obtained.
[0040]
(1) According to the mousse dispenser 10, if the cap 96 is pressed, the air supply bellows 70 and the water soap supply bellows 80 are compressed via the shaft 94 and the bellows upper support member 92, and the water soap is compressed by air. Since the foamed soap is discharged from the foam nozzle 150 after being foamed, the washing surface can be performed with the foamed soap.
[0041]
(2) Further, since the mousse dispenser 10 is fixedly installed close to the sink for the wash basin B, it is excellent in usability and there is no danger of being stolen when installed in a public place.
[0042]
(3) In the above embodiment, the air and the water soap fed from the air supply bellows 70 and the water soap supply bellows 80 are the water stone outflow soap passage 140b, the water stone outflow soap passage 140c formed in the shaft 94, and The air is sent to the bubble nozzle 150 via the air outflow passage 120b and the air outflow passage 120c. Therefore, the piping system for arranging the water soap outflow passage 140 and the air outflow passage 120c is simplified, that is, there is no need to make complicated piping connections in the case 20, and the assemblability is improved.
[0043]
(4) As a means for supplying air and water soap, the air supply bellows 70 and the water soap supply bellows 80 are realized, so that an electric configuration such as a motor is not required and the configuration is simple. In addition, there is no need to provide troublesome electric wiring around the water in consideration of insulation properties.
[0044]
(5) The amount of water soap for making foam soap in one operation is constant at the amount charged in the water soap chamber 80S, and the amount of air is also constant at the volume in the air chamber 70S. Since foamed soap is produced with a certain amount of water soap and air, an optimally foamed foamed soap is obtained, which is excellent in usability.
[0045]
(6) Since the water soap supply bellows 80 is formed to have a smaller diameter than the air supply bellows 70 and is disposed in the air supply bellows 70, the air supply bellows 70 and the water soap supply bellows 80 are connected to the case 20. And the capacity of the case chamber 20S in the case 20 can be increased. Therefore, the amount of water soap that can be accommodated in the case chamber 20S increases, and the number of times of filling the water soap decreases, thereby simplifying maintenance.
[0046]
(7) Since the cap 96 is provided as a pressing operation section and the foam nozzle 150 is provided as a foaming soap discharge section above the wash basin B above the case 20 of the mousse dispenser 10, the By operating at a position close to the sink for use, foam soap is discharged from the foam nozzle 150, which is convenient.
[0047]
(8) By arranging the cap 96 as the pressing operation unit and the foam nozzle 150 for receiving the foam soap in different places, the foam soap does not adhere to the upper surface 98a of the cap 96, and cleaning is performed. Easy.

When the push button 296 is manually pushed in this state, the bellows upper support member 291 moves downward integrally with the push button 296. Thus, the bellows upper support member 291 is integrated with the water soap outflow check valve 341 and the air outflow check valve 321 to compress the bellows 270 against the elastic force of the bellows 270 and the coil spring 283. At this time, the air in the air chamber 270S is sent to the bubble nozzle 350 via the air outflow check valve 321 and the air outflow passage 320. Since the outside air introduction passage 310 is provided with the outside air introduction check valve 311, the air in the air chamber 270 </ b> S does not escape to the atmosphere.
[0059]
At the same time, the water soap filled in the water soap chamber 280S reaches the foam nozzle 350 via the water soap outflow check valve 341 and the water soap outflow passage 340. Then, in the foam nozzle 350, the water soap is foamed with air to form foam soap, which is discharged from the nozzle outlet 354 through the nozzle passage 353b.
[0060]
When the pressing force of the push button 296 is released, the bellows 270 attempts to return to the original state by the restoring force of the bellows 270 and the urging force of the coil spring 283. At this time, the water soap is sucked into the water soap chamber 280S via the water soap introduction check valve 331 due to the negative pressure in the bellows 270. At the same time, air is introduced into the air chamber 270S via the outside air introduction port 310a, the outside air introduction pipe 310b, and the outside air introduction check valve 311. As a result, the water soap chamber 280S is filled with the water soap, and the air chamber 270S is filled with the air, and the apparatus enters a standby state for discharging the foamed soap.
[0061]
In the above embodiment, the air and the water soap sent from the air chamber 270S and the water soap chamber 280S are sent to the foam nozzle 350 through the water soap outflow passage 340 and the air outflow passage 320 formed in the shaft portion 293. . Therefore, the piping system for pressure-feeding the water soap outflow passage 340 and the air outflow passage 320 is simplified, and there is no need to make complicated piping connections in the case 220, and the assemblability is improved.
[0062]
Further, since the push button 296 as an operation unit is provided above the washstand B at the upper part of the case 220 of the mousse dispenser 210 and the foam nozzle 350 is provided as a discharge unit of foam soap, The foamed soap is discharged from the foam nozzle 350 by the operation at the position close to the part, and the usability is good.
[0063]
In addition, as shown in FIG. 6, by providing a capacity display portion 370 that can be seen from the outside on the outer surface of the case 220, the filling amount of the water soap can be visually recognized. This simplifies the maintenance of whether or not water soap is replenished.
[0064]
