Utility Model Registration No. 2517784

  In the ultraviolet sterilization apparatus described in Patent Document 1, the entire inner wall surface of the processing tank is covered with a cylinder made of an ultraviolet resistant material. For this reason, deterioration of the synthetic resin constituting the processing tank due to ultraviolet rays is prevented.

  However, in the ultraviolet sterilization apparatus described in Patent Document 1, the entire inner wall surface of the processing tank is covered with a cylinder. Therefore, the manufacturing cost of the ultraviolet sterilization apparatus described in Patent Document 1 increases.

  Furthermore, in the ultraviolet sterilization processing apparatus described in Patent Document 1, the lid is not inserted to the position where the lower end of the lid reaches the light emitting part of the ultraviolet lamp. Due to such a structure, the ultraviolet sterilization apparatus described in Patent Document 1 has a large size.

  In addition, in the ultraviolet sterilization apparatus described in Patent Document 1, the water supply port and the drain port are not covered with a cylinder. Therefore, in the ultraviolet sterilization processing apparatus described in Patent Document 1, the water supply port and the drain port are easily deteriorated by ultraviolet rays.

  The present invention has been made in view of the above problems of the prior art. More specifically, the present invention provides a sterilization apparatus and a hot water apparatus capable of suppressing deterioration due to ultraviolet rays while suppressing an increase in manufacturing cost and size.

  A sterilization apparatus according to one aspect of the present invention includes a sterilization lamp having a light-emitting portion, a cylindrical main body portion having an opening provided at an end portion and containing the sterilization lamp therein, and a main body portion A lid member that is attached to the opening and formed of a resin material, and a light shielding member. The main body is formed of a material that is less susceptible to deterioration by ultraviolet light than the lid member. The lid member has an inner peripheral surface. At least a part of the inner peripheral surface faces the light emitting unit. The light shielding member covers a portion of the inner peripheral surface that faces the light emitting portion.

  In the sterilization apparatus according to one embodiment of the present invention, the main body portion is made of a material that is less likely to be deteriorated by ultraviolet rays than the lid member. Therefore, it is not necessary to coat the inner wall of the main body with a material having ultraviolet resistance. Therefore, the sterilization apparatus according to one embodiment of the present invention can suppress an increase in manufacturing cost.

  In the sterilization apparatus according to one aspect of the present invention, the lid member is attached to the main body so that the inner peripheral surface thereof faces the light emitting unit of the sterilization lamp. For this reason, the portion of the lid member that overlaps the main body is widened. Therefore, the sterilization apparatus according to one embodiment of the present invention can suppress an increase in size. In the sterilization apparatus according to one aspect of the present invention, the inner peripheral surface facing the light emitting unit is covered with a light shielding member. Therefore, according to the sterilization apparatus according to one embodiment of the present invention, deterioration of the lid member due to ultraviolet rays can be suppressed.

  In the sterilization apparatus described above, the main body portion may have a contracted tube portion that is located at the end portion and is fitted into the lid member. The contraction tube portion may constitute a light shielding member.

  When the light shielding member is a separate member, a process for attaching the light shielding member is required when assembling the sterilization apparatus. That is, when the light shielding member is a separate member, the number of assembly steps increases. In the sterilization apparatus described above, the contracted tube portion located at the end of the main body portion constitutes a light shielding member, and therefore no separate process is required to attach the light shielding member. Therefore, when the contraction tube portion positioned at the end portion of the main body portion constitutes a light shielding member, the assembly process can be prevented from becoming complicated.

  In the above-described sterilization apparatus, the main body portion may have a fitting portion that is fitted into the opening. At least a part of the inner peripheral surface located in the fitting part may face the light emitting part. The light shielding member may be a protective film formed on the inner peripheral surface and made of a material that is less likely to be deteriorated by ultraviolet rays than the lid member. The protective film may be a plating film. The protective film may be formed of a paint that reflects ultraviolet rays.

  When the light shielding member is a protective film formed on the inner peripheral surface of the lid member, a separate process for attaching the light shielding member is not required when assembling the sterilization apparatus. Therefore, in this case, complication of the assembly process can be avoided.

  In the sterilization apparatus, the lid member may have a connection port through which a fluid to be sterilized enters and exits. The connection port may be disposed at a position not facing the light emitting unit.

  When the connection port is disposed at a position that does not face the light emitting unit, ultraviolet rays from the sterilization lamp do not leak from the connection port. Therefore, in this case, deterioration due to ultraviolet rays of the pipe connected to the connection port can be suppressed.

  The hot water apparatus which concerns on 1 aspect of this invention is provided with a circulation path and said disinfection apparatus arrange | positioned on a circulation path.

  According to the sterilization apparatus according to one embodiment of the present invention, deterioration due to ultraviolet rays can be suppressed while suppressing an increase in manufacturing cost and size.

That is, the cross section in the direction perpendicular to the central axis A of the main body 1 is preferably an annular shape. For the main body 1, a material that does not transmit ultraviolet rays and has ultraviolet resistance is used. That is, the main body 1 is made of a material that is less likely to be deteriorated by ultraviolet rays than the lid member 3. The main body 1 is preferably made of a material that reflects ultraviolet rays. Specifically, a metal material is used for the main body 1. The metal material used for the main body 1 is, for example, stainless steel.

  As shown in FIG. 2, a sterilization lamp protection tube 11 is provided inside the main body 1. The sterilization lamp protection tube 11 is a member for protecting the sterilization lamp 2 from a fluid flowing 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 ultraviolet light emitted from the sterilization lamp 2. For the sterilization lamp protection tube 11, for example, quartz glass is used.

  A 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 of the main body portion 1. At the end portion 13, the main body portion 1 has an opening 14. The main body 1 may have a contracted tube portion 15. The contracted tube portion 15 is located at the end portion 13. The main body 1 is contracted in the contracted tube portion 15. That is, the inner diameter of the main body portion 1 in the contracted tube portion 15 is smaller than the inner diameter of the main body portion 1 other than the contracted tube portion 15. It is smaller than the outer diameter of 1. The contracted tube portion 15 is formed, for example, by sandwiching the end portion of the main body portion 1 with a mold and performing pressure molding.

  The sterilization lamp 2 is a lamp that emits ultraviolet rays for sterilizing the fluid. For example, the sterilization 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 extends along a direction parallel to the central axis A of the main body 1. The sterilizing lamp 2 includes an electrical component 21 and a light emitting unit 22. The electrical part 21 is a part to which a socket, electrical parts, etc. are attached. Therefore, ultraviolet rays are not emitted from the electrical component unit 21. The electrical component 21 is disposed at the end of the sterilization lamp 2. The light emitting part 22 is a part from which ultraviolet rays are emitted.

  The first lid member 3 a has an inner side surface 31, an outer side surface 32, an outer peripheral surface 33, and an inner peripheral surface 34. The inner side surface 31 is an end surface on the main body 1 side. The outer side surface 32 is a surface opposite to the inner side surface 31. The outer peripheral surface 33 is a surface located on the outer peripheral side of the first lid member 3a. The inner peripheral surface 34 is a surface located on the inner peripheral side of the first lid member 3a.

  The outer peripheral surface 33 is preferably provided with a water inlet side connection port 33a. More preferably, the water inlet side connection port 33a is arranged on the outer peripheral surface 33 at a position not facing the light emitting portion 22 of the sterilizing lamp 2. The water inlet side connection port 33a has a hollow cylindrical shape inside. Therefore, a pipe (not shown) can be connected to the water inlet side connection port 33a. This pipe is usually made of a resin material. The water inlet side connection port 33 a is preferably offset from the central axis A of the main body 1.

  The first lid member 3 a is attached to the opening 14. The first lid member 3 a is attached so that at least a part of the inner peripheral surface 34 faces the light emitting unit 22. Here, the phrase “the inner peripheral surface 34 and the light emitting portion 22 face each other” means that the inner peripheral surface 34 and the light emitting portion 22 are arranged to face each other in the radial direction of the main body portion 1. More specifically, the first lid member 3 a is attached to the main body 1 by inserting the contracted tube portion 15 into the attachment portion 35. From another point of view, the portion of the inner peripheral surface 34 located at the attachment portion 35 that faces the light emitting portion 22 faces the contracted tube portion 15.

  A seal member 36 is disposed between the inner peripheral surface 34 located in the attachment portion 35 and the outer wall surface of the main body portion 1. The seal member 36 is, for example, an O ring. Thereby, the inner peripheral surface 34 located in the attachment part 35 and the outer wall surface of the main-body part 1 are sealed watertight, and the outflow of the fluid used as the sterilization object is prevented.

  A cavity 37 is provided inside the first lid member 3a. The cavity 37 opens to the inner side surface 31 side of the first lid member 3a. That is, the cavity 37 communicates with the flow path 12. The cavity 37 also communicates with the water inlet side connection port 33a. The inner diameter of the cavity 37 is larger than the outer diameter of the sterilization lamp protection tube 11. That is, a space is formed between the inner wall of the cavity 37 and the outer peripheral surface of the sterilization lamp protection tube 11. Therefore, the fluid to be sterilized introduced from the pipe flows into the flow path 12 provided inside the main body 1 via the water inlet side connection port 33 a and the cavity 37.

  A lamp insertion hole 38 is provided on the outer surface 32 side of the first lid member 3a. From the lamp insertion hole 38, the sterilizing lamp 2 is inserted into the main body 1. Therefore, the inner diameter of the lamp insertion hole 38 is larger than the outer diameter of the sterilizing lamp 2. The lamp insertion hole 38 is preferably provided in at least one of the first lid member 3a and the second lid member 3b.

  The end of the sterilization lamp protection tube 11 is inserted into the lamp insertion hole 38. A seal member 39 is disposed between the inner peripheral surface 34 located in 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. Thereby, the inner peripheral surface 34 of the first lid member 3a and the outer peripheral surface of the sterilization lamp protection tube 11 are sealed in a watertight manner, and the outflow of the fluid to be sterilized is prevented.

  The light shielding member 4 is disposed so as to cover the inner peripheral surface 34. The light shielding member 4 does not need to cover the entire inner peripheral surface 34. The light shielding member 4 only needs to cover at least a portion of the inner peripheral surface 34 facing the light emitting portion 22 of the sterilizing lamp 2. More specifically, the light shielding member 4 only needs to cover a portion of the inner peripheral surface 34 located in the attachment portion 35 that faces the light emitting portion 22.

  As described above, the inner peripheral surface 34 that is located in the attachment portion 35 and faces the light emitting portion 22 faces the contracted tube portion 15. Therefore, the light shielding member 4 can be configured by the contracted tube portion 15. That is, the light shielding member 4 may be configured integrally with the main body 1.

  A material having ultraviolet resistance is used for the light shielding member 4. The material used for the light shielding member 4 may reflect ultraviolet rays. A specific example of the material used for the light shielding member 4 is a metal material such as stainless steel.

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

  A resin material is used for the first lid member 3a and the second lid member 3b. This resin material is, for example, SPS (syndiotactic polystyrene).

  The fixing member 5 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 A. 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 5 has a central part 51 and a fixing part 52. The central part 51 is located at the center of the fixing member 5 and extends along the direction of the central axis A of the main body part 1. The fixing portion 52 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 5 is formed, for example, by bending a single plate-like member using a press die. For the fixing member 5, for example, SGCC (hot dip galvanized steel sheet) is used.

The operation of the sterilization apparatus according to Embodiment 1 will be described below.
A fluid to be sterilized is supplied into the main body 1 from the water inlet side connection port 33a of the sterilization apparatus according to the first embodiment. The supplied fluid to be sterilized flows through the flow path 12 inside the main body 1.

  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.

Below, the effect of the bacteria elimination apparatus which concerns on Embodiment 1 is demonstrated.
As described above, in the sterilization apparatus according to the first embodiment, the lid member 3 is attached to the main body 1 so that at least a part of the inner peripheral surface 34 faces the light emitting unit 22 of the sterilization lamp 2. Yes. As a result, the portion of the lid member 3 that overlaps the main body 1 is widened. Therefore, according to the sterilization apparatus according to the first embodiment, the sterilization apparatus can be reduced in height (the dimension in the direction parallel to the central axis A of the sterilization apparatus can be reduced).

  From another viewpoint, in the sterilization apparatus according to the first embodiment, a region for arranging the seal member 36 between the attachment portion 35 and the main body portion 1 is secured without increasing the height. It is possible to improve the water tightness between the lid member 3 and the main body 1.

  In the sterilization apparatus according to the first embodiment, a portion of the inner peripheral surface 34 facing the light emitting unit 22 of the sterilization lamp 2 is covered with the light shielding member 4. Therefore, according to the sterilization apparatus according to the first embodiment, it is possible to suppress the deterioration of the lid member 3 due to ultraviolet rays while reducing the height of the sterilization apparatus.

  In the sterilization apparatus according to the first embodiment, the main body 1 is formed of a material that is less likely to be deteriorated by ultraviolet rays than the lid member 3. Therefore, it is not necessary to cover the main body 1 with an ultraviolet resistant material. Therefore, according to the sterilization apparatus according to Embodiment 1, the manufacturing cost of the sterilization apparatus can be reduced.

  In the sterilization apparatus according to the first embodiment, when the main body 1 has the contracted tube portion 15 and the contracted tube portion 15 constitutes the light shielding member 4, the light shielding member 4 does not need to be a separate member. Therefore, in this case, a process for assembling the light shielding member 4 becomes unnecessary. Further, in this case, since the light shielding member 4 is formed integrally with the main body 1, there is no possibility that it will fall off from the lid member 3.

  Further, when the main body 1 has the contracted tube portion 15 and the contracted tube portion 15 constitutes the light shielding member 4, a structure for fixing the light shielding member 4 to the lid member 3 becomes unnecessary. Therefore, in this case, the lid member 3 can be reduced in size, and the sterilization apparatus can be further reduced in height. In addition, in this case, it is possible to make it difficult for hot water flowing through the flow path 12 to flow into the gap between the light shielding member 4 (contracted tube portion 15) and the inner peripheral surface 34 of the lid member 3.

  In the sterilization apparatus according to the first embodiment, when the water inlet side connection port 33a and the water outlet side connection port 33d are arranged at positions that do not face the light emitting part 22 of the sterilization lamp 2, ultraviolet rays emitted from the sterilization lamp 2 However, it is difficult to reach the pipe connected to the water inlet side connection port 33a and the water outlet side connection port 33d. Therefore, in this case, deterioration of the piping due to ultraviolet rays can be suppressed.
