[0008] <Embodiment> The deodorizing device 10 is positioned near the handwashing sink 11, as shown in Figure 1. The handwashing sink 11 is installed inside the toilet room. Hereinafter, for each component, the vertically upper side when positioned near the handwashing sink 11 will be referred to as the upper side, the lower side as the lower side, the inside of the toilet room as the front side, the opposite side as the rear side, the right side when viewed from the front as the right side, and the left side as the left side. In each figure, the positive direction of the X-axis is the right side, the negative direction of the X-axis is the left side, the positive direction of the Y-axis is the upper side, and the negative direction of the Y-axis is the lower side.

[0009] The handwashing basin 11 comprises a faucet unit 14, a drain unit 16, a counter 41, and a cabinet 42. The faucet unit 14 has a spout 15. Users can wash their hands, etc., by the water discharged from the faucet unit 14. In this specification, "water" includes not only cold water but also heated water.

[0010] The drain unit 16 comprises a bowl 17 and a drain pipe 20. The bowl 17 is located below the spout 15. A drain outlet 18 is provided at the bottom of the bowl 17. The bowl 17 receives the water discharged from the spout 15 and discharges the water into the drain pipe 20 through the drain outlet 18.

[0011] The drain pipe 20 discharges the wastewater from the bowl 17 into a floor drain pipe 13 located on the floor surface 12. The drain pipe 20 is housed in a storage space 43 of the cabinet 42. The drain pipe 20 has a first pipe section 21, a trap section 22, and a second pipe section 23. The trap section 22 is detachable from the first pipe section 21 and the second pipe section 23.

[0012] The first pipe section 21 is connected to the bottom of the bowl 17. The first pipe section 21 is in communication with the drain 18 of the bowl 17. The first pipe section 21 extends vertically downward.

[0013] As shown in Figure 2, the trap section 22 is connected to the downstream side of the first pipe section 21. The trap section 22 stores water inside and forms a water seal 34. The water seal 34 prevents foul odors and pests from entering from the floor drain pipe 13.

[0014] The trap section 22 has, in order from the upstream side, an upstream connection section 24, a descending section 25, a bottom section 26, an ascending section 27, and a downstream connection section 28. The upstream connection section 24 is connectable to the lower end of the first pipe section 21. The descending section 25 extends vertically downward from the upstream connection section 24. The upstream connection section 24 and the descending section 25 have a coaxial cylindrical shape. The bottom section 26 extends horizontally to the right from the lower end of the descending section 25. The bottom section 26 has a horizontally spreading, flattened shape. The ascending section 27 extends vertically upward from the rear end of the bottom section 26. The ascending section 27 has a rectangular parallelepiped shape. The upper end of the ascending section 27 is located above the upper end of the upstream connection section 24. The volume of the ascending section 27 is larger than the volume of the descending section 25. The horizontal cross-sectional size of the rising section 27 is larger than that of the descending section 25. The trap section 22 has a volume that makes it less likely for the water seal to break even when toilet wastewater, etc., is introduced into the second pipe section 23 and the drainage routes are integrated.

[0015] The upper surface of the rising section 27 is a horizontally extending, flat surface. The upper surface of the rising section 27 is rectangular in shape, longer in the left-right direction than in the front-back direction. The rising section 27 is provided with a connection section 53 for the exhaust pipe 52, which will be described later. The downstream connection section 28 extends horizontally to the right from the upper end of the rising section 27. The downstream connection section 28 is cylindrical in shape. The downstream connection section 28 can be connected to the upper end of the second pipe section 23.

[0016] As shown in Figure 2, the trap section 22 has a dip 29 and a wear 32. The dip 29 is the top of the bottom section 26. The dip 29 is the lowest part of the upper surface 33 of the bottom section 26 that connects the lower end of the rising section 27 and the lower end of the descending section 25. The wear 32 is the lower end of the overflow surface. The wear 32 is the lower end of the left end of the downstream connection section 28. The water seal surface 35 of the water seal 34 is created above the wear 32 by the upper end of the second pipe section 23 fitted inside the downstream connection section 28. The water seal surface 35 is the water surface of the highest water level of the water seal 34. The water seal surface 35 is formed in the trap section 22 and the first pipe section 21.

[0017] The trap section 22 has an inspection opening 36. The inspection opening 36 is located on the lower surface 37 of the bottom 26 of the trap section 22. The inside of the trap section 22 can be cleaned by removing the inspection opening 36.

[0018] The second pipe section 23 is connected to the downstream side of the trap section 22. The upper end of the second pipe section 23 is connected to the downstream connection section 28. The second pipe section 23 extends vertically downward from the downstream connection section 28 of the trap section 22. The lower end of the second pipe section 23 is connected to the floor drain pipe 13 on the floor surface 12.

[0019] As shown in Figure 1, the counter 41 is a plate-shaped member that extends in a substantially horizontal direction. The counter 41 is placed on the top surface of the cabinet 42. The counter 41 extends to the right from the cabinet 42. A paper holder is fixed to the counter 41. The bowl 17 is placed on top of the counter 41.

[0020] The cabinet 42 is provided below the bowl 17. The lower surface of the cabinet 42 is installed on the floor surface 12. The cabinet 42 is in the shape of a substantially rectangular parallelepiped box. The interior of the cabinet 42 is a vertically long storage space 43. The cabinet 42 has a door (not shown) on the front surface. The door can hide the drain pipe 20 disposed in the storage space 43. In the storage space 43, a toilet brush, a charm box, etc. can be arranged.

[0021] Through holes 44 are formed in the upper and lower directions on the top plates of the counter 41 and the cabinet 42. The lower part of the bowl 17 and the first pipe part 21 are connected at the through hole 44.

[0022] As shown in FIG. 2, the deodorizing device 10 has an intake part 51, an exhaust pipe 52 extending from the intake part 51, and a connection part 53 to which the exhaust pipe 52 is connected. The deodorizing device 10 is disposed at the upper end of the storage space 43 of the cabinet 42.

[0023] An air intake port 54 is provided in the intake part 51. The intake part 51 is disposed above the water sealing surface 35 of the drain pipe 20. The intake part 51 has a fan, a check valve, and an ion generator (not shown). The fan takes in the air in the storage space 43 from the air intake port 54 into the interior of the intake part 51, and pumps the taken-in air to the exhaust pipe 52. The check valve is provided downstream of the fan and the pump. The check valve allows the flow of air from the intake part 51 to the exhaust pipe 52, and restricts the flow of air from the exhaust pipe 52 to the intake part 51. The ion generator creates plasma cluster (registered trademark) ions and discharges them into the interior of the cabinet 42. Thereby, the interior of the cabinet 42 is sterilized. The air intake port 54, the fan, the check valve, and the ion generator of the deodorizing device 10 are disposed above the water sealing surface 35 of the drain pipe 20.

[0024] The exhaust pipe 52 is a hose made of synthetic resin. The exhaust pipe 52 extends from the upper surface of the intake part 51 and extends to the drain pipe 20. The portion of the exhaust pipe 52 from the intake part 51 to the connection part 53 is bent.

[0025] The exhaust pipe 52 extends from the connection part 53 into the interior of the trap part 22. The portion of the exhaust pipe 52 from the connection part 53 to the exhaust port 55 at the lower end extends vertically. The exhaust port 55 is located below the water seal surface 35 of the drain pipe 20. The exhaust port 55 opens into the water seal 34.

[0026] The exhaust port 55 is located below the dip 29 of the trap section 22. The exhaust port 55 opens downwards. Therefore, it is easy to clean the exhaust port 55 through the inspection port 36.

[0027] The exhaust port 55 is located in the downstream region R of the water seal 34. The downstream region R is the area of ​​the water seal 34 downstream (to the right in Figure 2) from the vertical reference plane 56 that passes through the dip 29. The reference plane 56 is a plane perpendicular to the XY plane.

[0028] The air from the storage space 43 taken in by the intake section 51 passes through the exhaust pipe 52 and is exhausted from the exhaust port 55 to the downstream area R of the seal water 34. The air exhausted to the downstream area R of the seal water 34 forms bubbles and floats on the seal water surface 35 of the rising section 27, and flows out from the upper end of the rising section 27 to the second pipe section 23.

[0029] The connection portion 53 is provided in the trap portion 22. The connection portion 53 is formed on the upper surface of the rise portion 27. The connection portion 53 penetrates the upper surface of the rise portion 27 in the vertical direction. The connection portion 53 is located above the water seal surface 35 of the drain pipe 20. The gap around the exhaust pipe 52 is sealed at the connection portion 53.

[0030] The embodiment configured as described above provides the following effects. The deodorizing device 10 is installed in the handwashing sink 11. The handwashing sink 11 is equipped with a drain pipe 20 having a trap section 22. The deodorizing device 10 has an intake section 51, an exhaust pipe 52, and a connection section 53. The intake section 51 is located near the handwashing sink 11. The exhaust pipe 52 extends from the intake section 51. The connection section 53 is provided in the drain pipe 20. The exhaust pipe 52 is connected to the connection section 53. The exhaust port 55 of the exhaust pipe 52 opens into the water seal 34 that accumulates in the trap section 22. With this configuration, since the exhaust port 55 is sealed by the water seal 34, even if the intake section 51 malfunctions, it is possible to prevent the odor from the exhaust pipe 52 from flowing back into the room.

[0031] The exhaust port 55 is located below the dip 29 of the trap section 22. With this configuration, even if the water level of the seal water 34 drops, the exhaust port 55 is reliably blocked by the seal water 34. Therefore, even if the intake section 51 malfunctions, it is possible to prevent odors from the exhaust pipe 52 from flowing back into the room.

[0032] The trap section 22 is detachable from the first pipe section 21 and the second pipe section 23 that constitute the drain pipe 20. The connecting section 53 is provided on the trap section 22. With this configuration, by removing the existing trap section and installing the trap section 22 with the connecting section 53 in its place, a deodorizing function can be added to existing equipment simply by replacing the trap section.

[0033] The connection portion 53 is located above the water seal surface 35 of the drain pipe 20. This configuration makes it less likely for water to leak from the connection portion 53 compared to when the connection portion 53 is located below the water seal surface 35 of the drain pipe 20.

[0034] The intake section 51 is positioned above the water seal surface 35 of the drain pipe 20. This configuration makes it less likely for water to leak to the intake section 51 compared to when the intake section 51 is located below the water seal surface 35 of the drain pipe 20.

[0035] The intake section 51 and the trap section 22 are located inside the cabinet 42. With this configuration, odors from the cabinet 42 can be exhausted to the exhaust pipe 52, allowing the cabinet 42 to be used comfortably.

[0036] The intake section 51 has an ion generator. With this configuration, the inside of the cabinet 42 can be disinfected, so the cabinet 42 can be used comfortably.
