The introduction pipe 10e corresponds to the water inlet 33a, and the discharge pipe 10f corresponds to the water outlet 33d. The first through hole 10g corresponds to the lamp insertion hole 37 of the first lid member 3a, and the second through hole 10h corresponds to the lamp insertion hole 37 of the second lid member 3b. The first insertion member 10i and the second insertion member 10j correspond to the lamp fixing member 22.

In the following, as a configuration example of the sterilization apparatus according to the embodiment, a case where the housing 10 has the main body 1 and the lid member 3 will be described.

The main body 1 has a tubular shape. Preferably, the main body 1 has a cylindrical shape. That is, it is preferable that the cross section of the housing 10 in the direction perpendicular to the central axis A1 has a circular shape. For the main body 1, for example, stainless steel or the like is used.

The main body 1 has a channel 11 inside. A fluid to be sterilized (for example, hot water) flows through the flow path 11. The space between the outer peripheral surface of the sterilization lamp protection tube 12 and the inner peripheral surface of the main body 1 described below serves as the flow path 11. That is, the flow path 11 is defined by the outer peripheral surface of the disinfection lamp protection tube 12 and the inner peripheral surface of the main body 1.

A disinfection lamp protection tube 12 is arranged inside the main body 1. The sterilization lamp protection tube 12 is a member for protecting the sterilization lamp 2 from the fluid to be sterilized which flows through the flow path 11. The disinfection lamp protection tube 12 preferably has a cylindrical shape. The disinfection lamp protection tube 12 is longer than the main body 1. The disinfection lamp protection tube 12 is transparent to the light emitted from the disinfection lamp 2. Quartz glass, for example, is used for the disinfection lamp protection tube 12.

The body portion 1 has end portions 1 a at both ends of the body portion 1. The end portion 1a is a portion located at an end in a direction parallel to the central axis A1 of the housing 10. At the end 1a, the main body 1 has an opening 1b. The main body 1 has openings 1b at both ends 1a. The end portion 1a preferably has a shape that widens in the outer peripheral direction when viewed from a direction parallel to the central axis A1 of the housing 10. This makes it easy to insert the lid member 3 into the main body 1.

The disinfection lamp 2 is a lamp that emits light for disinfecting a fluid. Preferably, the disinfection lamp 2 is a fluorescent lamp that emits ultraviolet rays. The sterilization lamp 2 may be an LED (Light Emitting Diode) that emits ultraviolet rays. That is, the disinfection lamp 2 is not particularly limited as long as it is a lamp that disinfects a fluid.

The disinfection lamp 2 is arranged inside the main body 1. Specifically, the disinfection lamp 2 is inserted inside the disinfection lamp protection tube 12. From another viewpoint, the outer peripheral surface of the disinfection lamp 2 is surrounded by the disinfection lamp protection tube 12. The sterilization lamp 2 has a shape extending in a direction parallel to the central axis A1 of the housing 10. The end of the sterilization lamp 2 is an electrical component 21 to which a socket and electrical components are attached.

The first lid member 3 a has an inner side surface 31, an outer side surface 32, and an outer peripheral surface 33. The inner side surface 31 is a surface that is inserted into the main body 1. The outer side surface 32 is a surface opposite to the inner side surface 31. A water inlet 33a is provided on the outer peripheral surface 33. The water inlet 33a has a hollow cylindrical shape. More specifically, the inside of the water inlet 33a serves as a water inlet side connection port 33b. The water inlet 33a extends radially outward from the outer peripheral surface 33 of the first lid member 3a.

The inner surface 31 side of the first lid member 3a is a tip portion 34. The tip portion 34 has an outer diameter substantially equal to the inner diameter of the main body 1. The first lid member 3a is arranged in the opening 1b by inserting the tip portion 34 into the opening 1b of the main body 1. A seal member 35 is arranged between the tip 34 and the end 1 a of the body 1. The seal member 35 is, for example, an O-ring. As a result, the opening 1b is closed and the fluid to be sterilized is prevented from flowing out of the main body 1.

A cavity 36 is provided inside the first lid member 3a. The cavity 36 is located closer to the outer surface 32 than the tip portion 34 is. The cavity 36 is open to the inner surface 31 side of the first lid member 3a. As a result, the cavity 36 communicates with the flow path 11. The inner diameter of the cavity 36 is larger than the outer diameter of the sterilization lamp protection tube 12. As a result, a space is formed between the inner wall 36a of the cavity 36 and the outer peripheral surface of the germicidal lamp protection tube 12. Therefore, the fluid to be sterilized, which has been injected into the water inlet side connection port 33b, flows into the flow path 11 provided inside the main body 1 through the cavity 36.

A lamp insertion hole 37 is provided on the outer surface 32 side of the first lid member 3a. The sterilization lamp 2 is inserted into the main body 1 through the lamp insertion hole 37. Therefore, the inner diameter of the lamp insertion hole 37 is larger than the outer diameter of the sterilization lamp 2. The lamp insertion hole 37 is preferably provided in at least one of the first lid member 3a and the second lid member 3b.

The first through hole 10g communicates with the internal space of the housing 10. That is, when the housing 10 has the main body 1 and the lid member 3, the lamp insertion hole 37 communicates with the cavity 36. The inner diameter of the lamp insertion hole 37 is substantially equal to the outer diameter of the disinfection lamp protection tube 12.

The end portion of the disinfection lamp protection tube 12 is inserted into the lamp insertion hole 37. A seal member 38 is arranged between the first lid member 3 a and the outer peripheral surface of the sterilization lamp protection tube 12. More specifically, a seal member 38 is arranged between the inner peripheral surface of the lamp insertion hole 37 and the outer peripheral surface of the sterilization lamp protection tube 12. The seal member 38 is, for example, an O-ring. Thereby, the first lid member 3a and the outer peripheral surface of the sterilization lamp protection tube 12 are watertightly sealed, and the fluid to be sterilized is prevented from flowing out from the first lid member 3a.

The housing 10 may have a lamp fixing member 22. The lamp fixing member 22 has a convex portion 22a. The convex portion 22 a is inserted into the lamp insertion hole 37. The convex portion 22a prevents the disinfection lamp 2 from coming off the lamp insertion hole 37. The lamp fixing member 22 is fixed to the outer side surface 32 of the first lid member 3a with, for example, a screw. For the lamp fixing member 22, for example, SPS (Syndiotactic Polystyrene) or the like is used.

As shown in FIG. 3, the first lid member 3a has a first ventilation port 10c. The first ventilation port 10c is formed on the outer side surface 32 of the first lid member 3a. The first ventilation port 10c communicates with the space between the inner peripheral surface of the sterilization lamp protection tube 12 and the sterilization lamp 2.

It is preferably located inside the area to be filled. The shape of the first ventilation port 10c in plan view is, for example, a circle, an ellipse, a rectangle, an oval, or the like. The shape of the first ventilation port 10c in plan view is preferably a shape having a longitudinal direction (for example, an elliptical shape, a rectangular shape, an oval shape, or the like).

When the shape of the first vent hole 10c in plan view is a shape having a longitudinal direction, the longitudinal direction of the first vent hole 10c in plan view (indicated by a dashed line B in FIG. 3) is The direction in which 33a extends from the outer peripheral surface 33 of the first lid member 3a (indicated by a dashed line C in FIG. 3) and the direction in which the water outlet 33d extends from the outer peripheral surface 33 of the second lid member 3b (see FIG. 3) (indicated by the one-dot chain line D). More preferably, the longitudinal direction of the first vent 10c in plan view, the direction in which the water inlet 33a extends from the outer peripheral surface 33 of the first lid member 3a, and the water outlet 33d extend from the outer peripheral surface 33 of the second lid member 3b. The direction is orthogonal.

The case where the longitudinal direction of the first ventilation port 10c in plan view and the direction extending from the outer peripheral surface 33 of the water inlet portion 33a (or the direction extending from the outer peripheral surface 33 of the water outlet portion 33d) are orthogonal to each other This refers to the case where the angle formed by the longitudinal direction of the mouth 10c in plan view and the direction extending from the outer peripheral surface 33 of the water inlet portion 33a (or the direction extending from the outer peripheral surface 33 of the water outlet portion 33d) is 90°±10°.

As shown in FIG. 4, the first ventilation port 10c may be formed so as to straddle the end of the lamp fixing member 22. Moreover, the number of the first vent holes 10c may be plural.

The second lid member 3b has a water outlet 33d and a water outlet side connection port 33e in place of the water inlet portion 33a and the water inlet side connection port 33b, and a second air outlet 10d in place of the first air outlet 10c. Except having it, it has the same configuration as the first first lid member 3a. Preferably, the second lid member 3b has the same shape as the first lid member 3a.

For example, a resin material is used for the first first lid member 3a and the second lid member 3b. This resin material is, for example, SPS or the like.

The fixing member 4 is arranged so as to sandwich the first lid member 3a and the second lid member 3b and the main body 1 from the direction of the central axis A1 of the housing 10. As a result, the first lid member 3a and the second lid member 3b are fixed to the main body 1. The fixing member 4 has a central portion 41 and a fixing portion 42. The central portion 41 is located at the center of the fixing member 4 and extends along the central axis direction of the main body 1. The fixing portion 42 is fixed to the outer side surfaces 32 of the first lid member 3a and the second lid member 3b with screws or the like.

The fixing member 4 is formed, for example, by bending a single plate-shaped member using a press die. For the fixing member 4, for example, SGCC (hot dip galvanized steel sheet) is used.

The operation of the sterilization apparatus according to the embodiment will be described below. A fluid to be sterilized is supplied to the inside of the housing 10 from the introduction pipe 10e of the sterilization apparatus according to the embodiment. The supplied fluid to be sterilized flows around the sterilization lamp protection tube 12 inside the housing 10.

While the fluid to be sterilized flows inside the housing 10, the fluid to be sterilized is irradiated with ultraviolet rays from the sterilization lamp 2. As a result, various bacteria contained in the fluid to be sterilized are sterilized. Then, the fluid sterilized in the housing 10 flows out from the discharge pipe 10f. As described above, the sterilization process is performed when the fluid to be sterilized passes through the sterilization apparatus according to the embodiment.

During the disinfection process, the temperature of the disinfection lamp 2 rises. Along with that, the temperature of the air around the disinfection lamp 2 rises. As a result, the density of air around the sterilization lamp 2 becomes lower than the density of air around the sterilization apparatus according to the embodiment.

As described above, the housing 10 is provided with the first ventilation port 10c and the second ventilation port 10d. The first ventilation port 10c and the second ventilation port 10d communicate with the space between the disinfection lamp 2 and the inner peripheral surface of the disinfection lamp protection tube 12. Therefore, the air around the sterilization lamp 2 becomes an updraft toward the second ventilation port 10d and is discharged to the outside from the second ventilation port 10d.

As the air around the sterilization lamp 2 is discharged to the outside from the second ventilation port 10d, the outside air is discharged from the first ventilation port 10c to the inner peripheral surface of the sterilization lamp protection tube 12 and the sterilization lamp 2. Is inhaled into the space between. The temperature of the outside air is lower than the temperature of the air around the sterilization lamp 2. Therefore, the sterilization lamp 2 is cooled by the flow of the air.

The effects of the sterilization apparatus according to the embodiment will be described below. As described above, in the disinfection device according to the embodiment, the housing 10 communicates with the space between the disinfection lamp 2 and the inner peripheral surface of the disinfection lamp protection tube 12, and the first ventilation port 10c and the second ventilation port 10c. It has a mouth 10d. Therefore, according to the sterilization apparatus according to the embodiment, the air around the sterilization lamp 2 is discharged to the outside from the second ventilation port 10d which is one ventilation port, and the outside air is the other ventilation port which is the first ventilation port. Due to the draft effect of being sucked from the ventilation port 10c, it becomes possible to cool the sterilization lamp 2 during use.

In the sterilization apparatus according to the embodiment, at least one of the first ventilation port 10c and the second ventilation port 10d is located inside a region defined by the outline of the electrical component portion 21 of the sterilization lamp 2 in plan view. In this case, it is difficult for the light emitted from the disinfection lamp 2 to reach the outside through the ventilation hole. Therefore, in this case, it is possible to prevent the light emitted from the sterilization lamp 2 from leaking to the outside of the sterilization apparatus.

In the sterilization apparatus according to the embodiment, the longitudinal direction of the first ventilation port 10c and the second ventilation port 10d in plan view intersects the direction in which the introduction pipe 10e and the discharge pipe 10f extend from the outer peripheral surface of the housing 10. In this case, the light emitted from the germicidal lamp 2 is unlikely to leak in the direction in which the introduction pipe 10e and the discharge pipe 10f extend from the outer peripheral surface of the housing 10. Pipes are connected in a direction in which the introduction pipe 10e and the discharge pipe 10f extend from the outer peripheral surface of the housing 10. Therefore, an operator who installs, maintains, etc. the sterilization apparatus according to the embodiment usually works by facing the introduction pipe 10e and the discharge pipe 10f in the direction extending from the outer peripheral surface of the housing 10. Therefore, in this case, it is possible to prevent the light emitted from the germicidal lamp 2 from entering the eyes of the operator.

In the disinfection device according to the embodiment, when the housing 10 has the first through hole 10g, the second through hole 10h, the first insertion member 10i, and the second insertion member 10j, the first insertion member 10i or the first insertion member 10i The sterilization lamp 2 can be exchanged only by removing the 2 insertion member 10j. Therefore, in this case, the sterilization lamp can be easily replaced while allowing the sterilization lamp to be cooled during use.

In the sterilization apparatus according to the embodiment, when the first ventilation port 10c (second ventilation port 10d) is formed so as to straddle the end of the first insertion member 10i (second insertion member 10j), the electrical component portion 21 The connected wiring can be easily passed through the first ventilation port 10c, and the workability is improved.

In the sterilization apparatus according to the embodiment, when the number of the first ventilation ports 10c (second ventilation ports 10d) is plural, the opening area of the first ventilation ports 10c becomes large, and thus the sterilization lamp can be cooled more efficiently. It becomes possible to do.
