In the drawings, the same or corresponding parts are denoted by the same reference numerals. Moreover, you may combine arbitrarily at least one part of embodiment described below. Furthermore, dimensional relationships such as length, width, thickness, and depth are changed as appropriate for clarity of the drawings, and do not represent actual dimensional relationships.

  As shown in FIG. 1, the sterilization apparatus according to the embodiment includes a main body 1, a sterilization lamp 2, and a lid member 3. The lid member 3 includes a pair of a first lid member 3a and a second lid member 3b. The sterilization apparatus according to the embodiment may further include a fixing member 4.

  The main body 1 has a cylindrical shape. Preferably, the main body 1 has a cylindrical shape. In other words, the cross section in the direction perpendicular to the central axis A1 of the main body 1 is preferably circular. For the main body 1, for example, stainless steel is used.

  As shown in FIG. 2, a sterilization lamp protection tube 11 is provided inside the main body 1. The sterilization lamp protection tube is a member for protecting the sterilization lamp 2 from a fluid flowing inside the main body 1. The sterilization lamp protection tube 11 is disposed inside the main body 1. The sterilization lamp protection tube 11 preferably has a cylindrical shape. The sterilization lamp protection tube 11 is longer than the main body 1. The sterilization lamp protection tube 11 is transparent to the light emitted from the sterilization lamp 2. For the sterilization lamp protection tube 11, for example, quartz glass is used.

  The main body 1 has a flow path 12. The channel 12 is provided inside the main body 1. More specifically, the flow path 12 is a space defined by the outer peripheral surface of the sterilization lamp protection tube 11 and the inner wall surface of the main body 1. A fluid (for example, hot water) to be sterilized flows through the flow path 12.

  The main body 1 has an end 13. The end portion 13 is a portion located at an end in a direction parallel to the central axis A <b> 1 of the main body portion 1. At the end 13, the main body 1 has an opening 14. The main body 1 preferably has an opening 14 at both ends 13. Preferably, the end portion 13 has a shape spreading in the outer peripheral direction when viewed from a direction parallel to the central axis A1 of the main body portion 1. Thereby, it becomes easy to insert the lid member 3 into the main body 1.

  The sterilization lamp 2 is a lamp that emits light for sterilizing the fluid. Preferably, the sterilizing 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 sterilization lamp 2 is not particularly limited as long as it is a lamp that sterilizes the fluid. The sterilization lamp 2 is disposed inside the main body 1. More specifically, the sterilization lamp 2 is inserted into the sterilization lamp protection tube 11. The sterilization lamp 2 has a shape extending in a direction parallel to the central axis A1 of the main body 1. 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 on the side inserted into the main body 1. The outer side surface 32 is a surface opposite to the inner side surface 31. A water inlet 33 a is provided on the outer peripheral surface 33. The water inlet 33a has a hollow cylindrical shape inside. Specifically, the inside of the water inlet 33a is a water inlet side connection port 33b. The water inlet side connection port 33b is offset from the central axis A1 of the main body 1.

  The inner surface 31 side of the first lid member 3 a is a tip end portion 34. The distal end portion 34 has an outer diameter substantially equal to the inner diameter of the main body portion 1. The first lid member 3 a is disposed in the opening portion 14 by inserting the distal end portion 34 into the opening portion 14 of the main body portion 1. A seal member 35 is disposed between the distal end portion 34 and the end portion 13 of the main body portion 1. The seal member 35 is, for example, an O ring. Thereby, the opening part 14 is closed and the fluid used as the sterilization object is prevented from flowing out from the main body part 1.

  A cavity 36 is provided inside the first lid member 3a. The cavity 36 is located on the outer surface 32 side with respect to the distal end portion 34. The cavity 36 opens to the inner side surface 31 side of the first lid member 3a. Thereby, the cavity 36 communicates with the flow path 12. The inner diameter of the cavity 36 is larger than the outer diameter of the sterilization lamp protection tube 11. Therefore, a space is formed between the inner wall 36 a of the cavity 36 and the outer peripheral surface of the sterilization lamp protection tube 11. This space is a flow path 37 in the lid. The cavity 36 communicates with the water inlet side connection port 33b. Therefore, the flow path 37 in the lid communicates with the water inlet side connection port 33b on one side.

  The in-lid flow path 37 is a space between the inner wall 36 a of the cavity 36 and the outer peripheral surface of the sterilization lamp protection tube 11, and the sterilization lamp protection tube 11 is disposed in parallel with the central axis A <b> 1 of the main body 1. Therefore, the in-lid flow path 37 is provided so as to circulate around the central axis A1 of the main body 1.

  As described above, since the cavity 36 is open on the inner surface 31 side, the fluid to be sterilized injected into the water-inlet side connection port 33b flows through the cavity 36 inside the main body 1. It flows to the road 12. That is, the in-lid flow channel 37 communicates with the flow channel 12 on the other side.

  As shown in FIG. 3 (in FIG. 3, in order to clarify the shape of the inner wall 36a of the cavity 36, members other than the first lid member 3a are not shown), the inner wall of the cavity 36 is shown. 36a inclines so that it may become near the main-body part 1 side, as it distances from the water-inlet side connection port 33b. That is, the inner wall 36a of the cavity 36 is inclined so as to approach the main body 1 as it goes around the central axis A1 of the main body 1 from the water inlet side connection port 33b toward the flow path 12. For this reason, the in-lid channel 37 is inclined so as to approach the main body 1 as it goes from the water inlet side connection port 33 b toward the channel 12.

  As shown in FIG. 4 (in FIG. 4, in order to clarify the positional relationship between the position of the inner wall 36a of the cavity 36 and the water inlet side connection port 33b, illustration of members other than the first lid member 3a is omitted. The in-lid flow path 37 is preferably inclined so as not to overlap each other in the direction of the central axis A1 of the main body 1.

  From another point of view, the inner wall 36a of the cavity 36 has a portion located at the end of the in-lid flow path 37 on the inflow side connection port 33b side of the in-lid flow path 37 on the inflow side connection port 33b side. It is preferable to incline so that it may not overlap with the part located in the place which turned center axis line A1 of the main-body part 1 from the edge of this.

  As shown in FIG. 5, the width of the water inlet side connection port 33 b in the direction perpendicular to the central axis A <b> 1 of the main body 1 is the width W <b> 1 at the portion communicating with the cavity 36. The water inlet side connection port 33b has a parallel portion 33ba. In the parallel portion 33ba, the inner peripheral surface of the water inlet side connection port 33b is parallel to the central axis A2 of the water inlet side connection port 33b. The width of the water inlet side connection port 33b in the direction perpendicular to the central axis A1 of the main body 1 is the width W2 at the parallel portion 33ba. The width W1 is narrower than the width W2. As a result, as shown in FIG. 6, the cavity 36 and the water inlet side connection port 33 b communicate with each other in the fluid channel to be sterilized constituted by the in-lid flow channel 37 and the water inlet side connection port 33 b. The width is narrow before and after the portion.

  As shown in FIG. 7, the height of the cavity 36 in the direction parallel to the central axis A1 of the main body 1 is a height H1 in the portion communicating with the water inlet side connection port 33b. The maximum height of the water inlet side connection port 33 b is a height H <b> 2 at a portion communicating with the cavity 36. The height H1 is higher than the height H2. As a result, as shown in FIG. 8, the cavity 36 and the water inlet side connection port 33b communicate with each other in the flow channel of the fluid to be sterilized constituted by the in-lid flow channel 37 and the water inlet side connection port 33b. The height is high before and after the part.

  As shown in FIG. 2, a lamp insertion hole 38 is provided on the outer surface 32 side of the first lid member 3a. The lamp insertion hole 38 communicates with the cavity 36. The inner diameter of the lamp insertion hole 38 is substantially equal to the outer diameter of the sterilization lamp protection tube 11.

  The end of the sterilization lamp protection tube 11 is inserted into the lamp insertion hole 38. A seal member 39 is provided between the lamp insertion hole 38 and the outer peripheral surface of the sterilization lamp protection tube 11. The seal member 39 is, for example, an O-ring. This prevents the fluid to be sterilized from flowing out of the first lid member 3a.

  A lamp fixing member 22 is provided on the outer surface 32 of the first lid member 3a. The sterilization lamp 2 installed inside the sterilization lamp protection tube 11 is fixed by the lamp fixing member 22 through the lamp insertion hole 38 of the first lid member 3a. The lamp fixing member 22 is fixed on the outer surface 32 of the first lid member 3a with, for example, screws. For the lamp fixing member 22, for example, SPS or the like is used.

  The second lid member 3b is the same as the first lid member 3a except that the second lid member 3b has a water outlet 33d and a water outlet side connection port 33e instead of the water inlet 33a and the water inlet side connection port 33b. It has a configuration. Preferably, the second lid member 3b has the same shape as the first lid member 3a.

  Here, when the second lid member 3b has the same shape as the first lid member 3a, the first lid member 3a and the second lid member 3b have the completely same shape. The case where the shape of the 1st cover member 3a and the shape of the 2nd cover member 3b correspond within the range of a manufacturing error is included.

  The fixing member 4 is disposed so as to sandwich the first lid member 3 a and the second lid member 3 b and the main body 1 from the central axis direction of the main body 1. As a result, the first lid member 3 a and the second lid member 3 b are fixed to the main body 1. The fixing member 4 has a central part 41 and a fixing part 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 portion 1. The fixing portion 42 is fixed to the outer surface 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-like member using a press die. For the fixing member 4, for example, SGCC (hot dip galvanized steel sheet) is used.

  Below, operation | movement of the microbe removal apparatus which concerns on embodiment is demonstrated. A fluid to be sterilized is supplied to the water inlet side connection port 33b of the sterilization apparatus according to the embodiment. The supplied fluid to be sterilized flows through the flow path 12 provided inside the main body 1. Since the water inlet side connection port 33b is provided offset from the central axis A1 of the main body 1, the supplied fluid to be sterilized flows through the flow path 12 as a swirling flow.

  While the fluid to be sterilized flows through the flow path 12, the fluid to be sterilized is irradiated with ultraviolet rays from the sterilization lamp 2. Thereby, various germs contained in the fluid to be sterilized are sterilized. Thereafter, the fluid sterilized in the flow path 12 flows out from the outlet side connection port 33e. As described above, the sterilization process is performed when the fluid to be sterilized passes through the sterilization apparatus according to the embodiment.

The other end of the heat exchanger 52e is connected to one end of the pipe 52c. The other end of the pipe 52 c is connected to the circulation adapter 61. A burner 52f is disposed in the vicinity of the heat exchanger 52e. A circulation pump 52g is provided on the pipe 52a. In addition, when attaching the sterilization apparatus 52d to the housing | casing of a hot-water supply apparatus, the center part 41 of the fixing member 4 becomes a guide for attachment.

  The pouring path 53 is a path through which hot water flows from the hot water supply path 51 into the bath circulation path 52. One end of the pouring path 53 is connected to the hot water supply path 51. More specifically, one end of the pouring passage 53 is connected to the pipe 51b. The other end of the pouring path 53 is connected to the bath circulation path 52. More specifically, the other end of the pouring passage 53 is connected to the pipe 52b. A pouring valve 53 a is provided on the pouring passage 53.

  The circulation adapter 61 is provided in the bathtub 6. The circulation adapter 61 has a discharge port and a suction port.

Below, operation | movement of the hot water supply apparatus as an example of the hot water apparatus which concerns on embodiment is demonstrated.
First, the hot water supply operation will be described. The supplied clean water is supplied to the heat exchanger 51c through the pipe 51a.

Thereby, the sterilization of the hot water in the bathtub 6 is performed. The hot water sterilized in the sterilization apparatus 52d may be heated in the heat exchanger 52e. That is, the sterilization operation may be performed during the chasing operation.

(Effects of the sterilization apparatus and hot water apparatus according to the embodiment)
In the sterilization apparatus according to the embodiment, the in-lid flow channel 37 circulates around the central axis A1 of the main body 1, and the main body 1 as it goes from the water inlet side connection port 33b toward the flow channel 12 side. It is inclined to approach. Therefore, in the sterilization apparatus according to the embodiment, pressure loss when the fluid to be sterilized supplied from the water inlet side connection port 33b becomes a swirling flow in the flow path 12 is suppressed.

  In addition, the sterilization apparatus according to the embodiment has such a configuration of the in-lid flow path 37, so that the fluid to be sterilized is hardly left when draining, and the flow path when passing water. The air in 12 is easy to escape.

  In the sterilization apparatus according to the embodiment, when the in-lid flow path 37 is inclined so as not to overlap with each other in the direction of the central axis A1 of the main body 1, the sterilization target supplied from the water inlet side connection port 33b And the fluid to be sterilized flowing through the in-lid channel 37 do not collide with each other. Therefore, in this case, pressure loss when the fluid to be sterilized supplied from the water inlet side connection port 33b becomes a swirling flow in the flow path 12 is further suppressed.

  In the sterilization apparatus according to the embodiment, when the height H1 is higher than the height H2, the width of the water inlet side connection port 33b is reduced at a portion where the water inlet side connection port 33b and the in-lid flow channel 37 communicate with each other. However, since the cross-sectional area of the flow path does not vary significantly, the pressure loss when the fluid to be sterilized supplied from the water inlet side connection port 33b turns into the swirl flow in the flow path 12 is further suppressed.

  In the sterilization apparatus according to the embodiment, when the first lid member 3a and the second lid member 3b have the same shape, the same member can be used in common. Therefore, in this case, the manufacturing cost can be reduced.

  In the hot water apparatus according to the embodiment, the pressure loss of the sterilization apparatus according to the embodiment can be suppressed, so that the load on the circulation pump 52g during the sterilization operation can be reduced. As a result, for example, it is possible to use the circulation pump 52g having a smaller output.

  It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is shown not by the above-described embodiment but by the scope of claims, and is intended to include meanings equivalent to the scope of claims and all modifications within the scope.
