The agent supply path 14, the pump 15 provided in the middle of the agent supply path 14 that pressurizes the liquid detergent supplied from the agent tank 12 and sends it to the foam detergent outlet 13, and the liquid detergent flowing through the agent supply path 14 And an ejector section 16 provided in the middle of the agent supply path 14 for mixing the liquid.

  The agent tank 12 stores a liquid detergent obtained by diluting a detergent stock solution containing a surfactant 5 to 10 times with water. The agent tank 12 is horizontally long and is provided with an agent inlet 17 on the upper surface of the foam detergent outlet 13 in the longitudinal direction, and an agent outlet 18 is provided on the lower surface of the agent tank 12.

  As shown in FIG. 5, the agent charging port 17 is formed in a cylindrical shape by projecting upward from the upper surface of the agent tank 12, and is located below the one mounting hole 11a of the flange 10a. A side cylinder 17a and an upper cylinder 17b inserted into the mounting hole 11a from above are configured. Both are connected by screwing a female thread portion formed on the inner peripheral surface of the lower cylindrical body 17a and a male thread portion formed on the outer peripheral surface of the upper cylindrical body 17b. A flange 20a is provided around the upper portion of the lower cylinder 17a as the lower holding portion 20, and the outer diameter of the upper portion of the upper cylinder 17b is larger than the outer diameter of the lower portion to form a large diameter portion 21a. The large-diameter portion 21 a is used as the upper clamping portion 21. As described above, the agent charging port portion 17 is formed by screwing the lower portion of the upper cylindrical body 17b inserted into the mounting hole 11a from above into the lower cylindrical body 17a, so that the flange 10a between the flange 20a and the large diameter portion 21a is engaged. The peripheral edge of the attachment hole 11a is sandwiched and attached to the flange 10a.

  The upper end portion of the upper cylindrical body 17b constituting the agent charging port portion 17 protrudes above the flange 10a of the bathtub 6, and water flowing on the flange 10a is prevented from flowing from the upper end opening of the agent charging port portion 17. ing. A lidded cylindrical inlet cap 23 is detachably attached to the upper end portion of the upper cylindrical body 17b. By removing the inlet cap 23, liquid detergent can be replenished from the agent inlet 17 into the agent tank 12. It has become. As shown in FIG. 14, a claw portion 76 is formed on the inner surface of the outer peripheral portion of the insertion port cap 23, and the upper end portion of the upper cylindrical body 17 b is fitted with the insertion port cap 23 to rotate the insertion port cap 23. By doing so, the claw portion 76 is detachably locked in a locking groove 77 formed on the outer peripheral surface of the upper cylindrical body 17b, whereby the insertion port cap 23 is detachable from the upper cylindrical body 17b. .

  When the inlet cap 23 is attached, a gap 25a is formed between the lower end of the inlet cap 23 and the upper surface of the flange 10a, and between the inner peripheral surface of the inlet cap 23 and the outer peripheral surface of the upper cylindrical body 17b. A gap 25b is formed. In addition, a plurality of protrusions 24 are formed in the circumferential direction on the upper end surface of the outer peripheral portion of the upper cylindrical body 17b, and the upper surface portion of the inlet cap 23 is mounted on the plurality of protrusions 24 in the attached state. Thus, a gap 25c is formed between the upper surface portion of the inlet cap 23 and the upper end portion of the upper cylindrical body 17b and between the adjacent protrusions 24.

  The inside of the agent tank 12 communicates with the outside (that is, inside the bathroom 4 above the flange 10a) through these gaps 25a to 25c. That is, the inlet cap 23 does not close the agent inlet 17 in a completely sealed state but is fitted to the agent inlet 17 in a non-sealed state. 5 is a strainer provided detachably on the agent charging port 17, and the strainer 27 can collect dust contained in the liquid detergent replenished from the agent charging port 17 into the agent tank 12. It is like that.

  As shown in FIGS. 1 and 2, the portion of the top surface of the agent tank 12 opposite to the agent charging port 17 side is one step higher than the portion where the agent charging port 17 is provided. An air reservoir 28 is formed at the upper end of the portion opposite to the agent inlet 17. Since the air reservoir 28 is located higher than the portion of the upper surface portion of the agent tank 12 where the agent inlet 17 is provided, the air reservoir 28 is filled even if liquid detergent is replenished to the agent tank 12 from the agent inlet 17 to the full. The part 28 is not filled with liquid detergent and air is collected. Therefore, even if the liquid detergent stored in the agent tank 12 is frozen in the winter, the air reservoir 28 can absorb the expanded portion of the frozen liquid detergent, and the agent tank 12 can be prevented from bursting due to the freezing of the liquid detergent. . Further, an air discharge port portion 29 connected to an air intake port portion 53 provided in the middle of an agent supply path 14 described later is provided on the side surface portion of the end portion of the air reservoir portion 28 on the agent input port portion 17 side. Yes.

  The agent supply path 14 includes an upstream flow path 30 upstream of the pump 15 and a downstream flow path 31 downstream of the pump 15.

  The upstream channel 30 is a channel connecting the agent discharge port 18 of the agent tank 12 and the suction port 15a of the pump 15, and is suspended downward from the lower surface of the agent tank 12, and the upstream side The downstream end of the flow path 30 is connected to the suction port 15 a of the pump 15 at a position below the agent tank 12. That is, the upper ends of the upstream flow path 30 and the suction port 15 a of the pump 15 are located below the agent tank 12, and the liquid detergent stored in the agent tank 12 flows between the agent tank 12 and the suction port 15 a of the pump 15. The head is supplied to the suction port 15a of the pump 15 using a head. Therefore, the pump 15 for sending the liquid detergent to the foam detergent outlet portion 13 can be a non-self-priming pump as in this example, whereby the pump 15 can be reduced in size and cost. In addition, since the upstream flow path 30 is suspended downward from the lower surface portion of the agent tank 12, the air contained in the liquid detergent in the upstream flow path 30 easily escapes to the agent tank 12 side. Biting is prevented.

  The upstream flow path 30 is formed by a vertical pipe 32, a sensor case 34, and an ejector pipe 35. The upper end portion of the vertical pipe 32 is connected in communication with the agent discharge port portion 18 of the agent tank 12. As shown in FIG. 6, the sensor case 34 has a bottomed vertical cylindrical flow path component 36, and the upper end of the flow path component 36 is a connection provided on the upper surface of the sensor case 34. An ejector pipe connection port 37 is formed on the side surface of the lower end portion of the flow path constituting portion 36 in communication with the lower end portion of the vertical pipe 32 via the cap 33.

  The flow path component 36 of the sensor case 34 is formed to have a larger diameter than the inner diameter of the vertical tube 32, and a water level sensor 38 that detects the water level of the liquid detergent is disposed in the flow path component 36. The water level sensor 38 is fixed by watertightly attaching its lower end to a sensor mounting hole 39 formed in the bottom surface of the flow path component 36. The water level sensor 38 is formed of a float sensor, and includes a columnar portion 40 that protrudes upward from the bottom surface of the flow path component 36 and a float 41 that is provided on the columnar portion 40 so as to be movable up and down. A reed switch (not shown) is incorporated in a portion of the columnar portion 40 located above the ejector pipe connection port portion 37. The reed switch is switched ON / OFF by the magnetic force of a magnet (not shown) provided on the float 41 when the float 41 is positioned at the same level as the reed switch. The control device 2 turns on the reed switch. / OFF detects whether the level of the liquid detergent in the flow path component 36 is equal to or lower than a predetermined level, and detects whether the agent tank 12 communicating with the flow path component 36 is empty.

  A connecting cylinder portion 42 is integrally provided on the outer surface of the sensor case 34 on the foam detergent outlet 13 side. The aforementioned ejector tube connection port 37 is provided inside the connecting tube portion 42, and one end portion of a substantially horizontal tubular ejector tube 35 is connected to the ejector tube connection port 37. The other end portion of the ejector pipe 35 protrudes outward from the end opening of the connecting cylinder portion 42 and is connected to the suction port portion 15a of the pump 15 housed in the pump case 44, thereby sequentially from the upstream side. The upstream flow path 30 is configured by the provided vertical pipe 32, the flow path section formed inside the connection cap 33, the flow path forming section 36, and the ejector pipe 35.

  Inside the ejector pipe 35, a throttle part 51 constituting a part of the upstream flow path 30 is formed. The throttle portion 51 is formed in a tapered cylindrical shape whose diameter decreases toward the downstream side, and an annular space 52 is formed between the outer peripheral surface of the throttle portion 51 and the inner peripheral surface of the ejector tube 35. . An air intake port 53 is formed on the upper surface of the ejector tube 35 as the ejector 16 communicating with the space 52. One end of an air intake tube 54 provided in the sensor case 34 is connected to the air intake port portion 53 in the connection cylinder portion 42, and the other end of the air intake tube 54 is connected to the connection cylinder of the sensor case 34. It protrudes upward through a hole 78 provided in the portion 42. The other end of the air intake pipe 54 protruding upward from the sensor case 34 is connected to the air discharge port 29 of the agent tank 12 through a hose shown by a one-dot chain line in FIG. The provided air intake port portion 53 is connected to the air discharge port portion 29 of the agent tank 12 through an air supply path 55 comprising an air intake tube 54 and a hose, whereby the space 52 in the ejector tube 35 is air. It communicates with the reservoir 28.

  When the pump 15 is driven as described above, a negative pressure is generated near the tip of the throttle 51 due to the flow of the liquid detergent in the ejector pipe 35, and the air in the air reservoir 28 of the agent tank 12 is caused by this negative pressure. While being supplied into the ejector pipe 35 through the air supply path 55, the air in the bathroom 4 is between the above-described gap 25 a between the inlet cap 23 and the flange 10 a, and between the inlet cap 23 and the agent inlet 17. Are supplied into the agent tank 12 through the 25b and 25c and the agent inlet 17 formed in this order. As a result, air from the air intake port 53 is mixed with the liquid detergent flowing in the ejector tube 35, and the liquid detergent (that is, foam detergent) mixed with the air is sent to the pump 15 side.

  Here, when air is taken into the liquid detergent flowing through the upstream flow path 30, the air intake port 53 is not directly opened to the atmosphere but opened to the atmosphere via the agent tank 12 for the following reason. That is, if the air supply path 55 is directly opened to the atmosphere, the liquid detergent in the agent supply path 14 flows backward from the air intake port 53 toward the air supply path 55 when the pump 15 is stopped from the operating state. In this example, the air intake port portion 53 is opened to the atmosphere via the agent tank 12, so that the liquid detergent that has flowed back flows from the air discharge port portion 29 to the air reservoir portion 28 of the agent tank 12. It was made to return inside.

  As described above, the pump 15 is a non-self-priming pump and is a non-waterproof pump. Since the pump 15 is a non-waterproof pump, it is housed in a waterproof pump case 44 as shown in FIG. 1 and FIG. The failure of the pump 15 is prevented. The pump 15 may be any type of pump such as an impeller type, a diaphragm type, and a plunger type, but preferably an impeller type or a diaphragm type pump having a function of stirring a foam detergent, It is preferable to make the bubbles contained in the discharged foam detergent finer. When the diameter of the bubbles contained in the foam detergent is made fine, there is an advantage that the surface area of the bubbles is increased, the contact efficiency against dirt is increased, the cleaning power is increased, the residence time on the wall surface is longer, etc. Preferably, the above-mentioned impeller type or diaphragm type pump is employed to discharge a foam detergent having a bubble diameter in the range of 10 to 100 μm and a void ratio of 50 to 80%.

  As shown in FIG. 6, a communication hole 57 is formed in the lower portion of the outer surface portion of the pump case 44 facing the suction port portion 15 a provided on the side surface of the pump 15, and the end of the ejector tube 35 protruding from the sensor case 34. The portion is inserted through the communication hole 57 and connected to the suction port 15 a of the pump 15. A flange portion 58 provided around the outer peripheral surface of the connecting cylinder portion 42 of the sensor case 34 is fixed to the peripheral portion of the communication hole 57 on the outer surface portion of the pump case 44 by a screw tool 59 (see FIG. 2). Thus, the sensor case 34 is attached to the pump case 44.

  The downstream channel 31 is a channel that connects the discharge port 15 b of the pump 15 and the foam detergent outlet 13, and is a connection port 63 that is separate from the pump case 44 that penetrates the upper surface of the pump case 44. And the downstream side pipe 64 that communicates and connects the foam detergent outlet 13 provided in the attachment hole 11b. The upstream side of the connection port 63 is connected to the discharge port 15 b provided on the upper surface of the pump 15 in the pump case 44. Note that the connection portion between the upper surface portion of the pump case 44 and the connection port portion 63 and the connection portion between the sensor case 34 and the pump case 44 are sealed with a sealant or the like. It is sealed except for the hole 57 and a communication hole 60 described later.

  A communication hole 60 is formed in the upper portion of the outer surface of the pump case 44 opposite to the sensor case 34. One end of a connection pipe 61 made of a flexible hose is connected to the communication hole 60, and the other end of the connection pipe 61 is connected to the wall of the bathroom 4 as shown in FIG. Connected to the bathroom 4 side. The connection pipe 61 is formed of a flexible hose in order to cope with the case where the construction position of the external communication pipe 19 is different at each site or when there is a hot water supply pipe or the like nearby. The construction of 61 is easy.

  Further, as shown in FIG. 6, the inner space of the pump case 44 communicates with a drainage space 45 formed in the sensor case 34 via a connecting cylinder 42 positioned below the communication hole 60. The drainage space 45 forms a sealed space except for the connecting cylinder 42. The drainage space 45 is formed in the lower part of the sensor case 34, and more specifically, is formed between the bottom of the flow path component 36 and the lower surface of the sensor case 34 in the sensor case 34. An insertion hole 46 is provided on the lower surface of the sensor case 34 that forms the bottom surface of the drainage space 45. The water level sensor 38 is inserted into the flow path component 36 of the sensor case 34 through the insertion hole 46 and the sensor attachment hole 39 and attached to the sensor attachment hole 39. A lid 47 constituting a part of the lower surface of the sensor case 34 is detachably attached to the insertion hole 46 by closing the hole 46.

  A drain hole 48 penetrating vertically is formed in the central portion of the lid 47, and the drain hole 48 is positioned below the communication hole portion 60 and the connecting cylinder portion 42 and can be elastically deformed. It is blocked by. The drain valve 50 normally maintains its closed state by its own elasticity, and in this state, the inner space of the pump case 44 communicating with the drainage space 45 is in a sealed state except for the communication hole 60. Therefore, the inner space of the pump case 44 is shielded from the environment in the surrounding bathroom 4 and is reliably waterproof. Further, the liquid detergent in the agent supply path 14 leaks into the pump case 44, and this liquid detergent may accumulate in the pump case 44 and the drainage space 45 communicating therewith, causing the pump 15 to break down. In this case, the drain valve 50 is set to be elastically deformed and opened by the liquid pressure of the liquid detergent accumulated in the drain space 45. Therefore, even if the liquid detergent leaks into the pump case 44, the liquid detergent can be discharged to the outside of the sensor case 34 through the drain valve 50, thereby preventing failure of the pump 15 due to liquid leakage. The liquid detergent discharged from the drain valve 50 falls onto the bathtub installation part 7b of the floor pan 7 below the sensor case 34 and is drained from a drain port (not shown) provided in the bathtub installation part 7b.

  As shown in FIG. 7, the foam detergent outlet 13 provided in the mounting hole 11b of the flange 10a of the bathtub 6 is inserted into the lower cylindrical body 13a located below the mounting hole 11b and the mounting hole 11b from above.

Connected. A flange 68 is provided around the upper end portion of the lower cylindrical body 13a, and the outer diameter of the upper portion of the upper cylindrical body 13b is larger than the outer diameter of the lower portion to form a large diameter portion 69. . The foam detergent outlet 13 is formed by screwing the lower part of the upper cylindrical body 13b inserted into the mounting hole 11b from above into the lower cylindrical body 13a as described above, so that the flange 68 and the large diameter part 69 are interposed therebetween. The attachment hole 11b portion of the flange 10a is sandwiched and attached to the flange 10a.

  A downstream side pipe connection port portion 70 that projects downward from the lower side cylindrical body 13a is formed at the lower end portion of the upper cylindrical body 13b that constitutes the foam detergent outlet portion 13, and the downstream side pipe connection port portion. A downstream pipe 64 is connected to 70. The upper end portion of the upper cylindrical body 13b protrudes above the flange 10a of the bathtub 6, and water flowing on the flange 10a is prevented from flowing from the upper end opening of the agent charging port portion 17. Further, a flexible and flexible discharge hose 66 as shown in FIG. 12 can be detachably connected to the upper portion of the upper cylindrical body 13b. When the discharge hose 66 is not connected to the foam detergent outlet portion 13, a covered cylindrical outlet portion cap 71 is detachably attached to the upper end portion of the upper cylindrical body 13b of the foam detergent outlet portion 13.

  The discharge hose 66 shown in FIG. 9 is provided with a discharge nozzle 65 that can be grasped by hand at one end and an adapter part 67 at the other end, and the adapter part 67 is connected to the upper cylindrical body 13b as shown in FIG. Removably attached to the upper part and connected. The discharge nozzle 65 provided at the tip of the discharge hose 66 is a switching nozzle, and a shower spray state in which foam detergent is discharged in a shower shape from a plurality of holes, and a straight spray state in which foam detergent is discharged from one hole. In addition, it is possible to switch to any one of the discharge stop states in which the discharge of the foam detergent is stopped. A check valve 75 shown in FIG. 12 is provided in the adapter portion 67 of the discharge hose 66. In the state where the adapter part 67 is connected to the foam detergent outlet part 13, the check valve 75 is pressed by the pin 56 provided in the foam detergent outlet part 13 as shown in FIG. In a state in which the adapter part 67 is not connected to the foam detergent outlet part 13, the foam detergent outlet part 13 is restored by the check valve 75 by closing the flow path in the adapter part 67 by an elastic force such as a spring. The liquid detergent remaining in the discharge hose 66 is prevented from leaking from the adapter portion 67 of the discharge hose 66 removed from the liquid hose 66 and applied to a person.
