Description

  The present invention relates to a bathroom unit, and more particularly to a bathroom unit in which light is introduced from the outside by a light guide facility.

  In recent years, a technique for providing an optical duct in a building such as a house has been developed. An optical duct is a cylindrical member that communicates from the outside to the inside of a building and whose inner surface is a light reflecting surface, and introduces outdoor natural light indoors. By providing such a light duct in a building, abundant natural light during the day can be used for indoor lighting, so that it is possible to save lighting costs and obtain an energy saving effect and an environmental load reduction effect. In addition, by introducing natural light into the room, the comfort of the room can be improved.

  Patent Document 1 discloses a technique for coupling an optical duct to a bathroom unit by providing an optical duct inside an exhaust duct communicated with the bathroom unit. However, in this technique, since the optical duct is housed inside the exhaust duct, the exhaust duct must be specially designed, which increases costs. Also, equipment associated with the exhaust duct, such as exhaust fins, must be specially designed, increasing costs. In addition, the exhaust duct has a large diameter, which restricts the routing in the ceiling and the installation position of the exhaust port on the outer wall of the building.

  On the other hand, when the light duct is provided separately from the exhaust duct, a light emission opening is provided separately from the exhaust opening on the ceiling of the bathroom unit. However, since a large number of functional members such as exhaust fins are arranged on the bathroom unit, providing a light emission port on the ceiling of the bathroom unit reduces the maintainability of these functional members.

Japanese Utility Model Publication No. 60-033240

  An object of the present invention is to provide a bathroom unit in which light is introduced from the outside by a light guide facility, and which has excellent maintainability of functional members.

  ADVANTAGE OF THE INVENTION According to this invention, light can be introduce | transduced from the outdoors with a light guide installation, and the bathroom unit excellent in the maintainability of a functional member is realizable.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a schematic cross-sectional view illustrating a building provided with a bathroom unit according to an embodiment of the present invention.
FIG. 2 is a perspective view illustrating a bathroom unit according to this embodiment.
FIG. 3 is a cross-sectional view illustrating the vicinity of the light emission port member in the bathroom unit.
FIG. 4 is a cross-sectional view illustrating the vicinity of the connection portion between the inspection port lid and the bracket in this bathroom unit.
FIG. 5 is a bottom view illustrating the vicinity of the inspection port of the bathroom unit.

  As shown in FIG. 1, the bathroom unit 1 according to this embodiment is installed in a building, for example, a house 101. In the house 101, an optical duct 102 as a light guide facility is disposed. One end of the light duct 102 is coupled to a daylighting unit 103 provided on the roof of the house 101, for example, and the other end is coupled to the bathroom unit 1. The daylighting unit 103 is covered with a dome made of a transparent plate, and does not allow sand or dust to pass therethrough but allows light to pass therethrough. The inside of the optical duct 102 is hollow, and its inner surface is a light reflecting surface. Thereby, the light duct 102 guides the outside light L introduced from the outside of the house 101 through the daylighting unit 103 while reflecting the light on the inner surface thereof, and introduces it to the inside of the bathroom unit 1.

  As shown in FIG.1 and FIG.2, in the bathroom unit 1 which concerns on this embodiment, the bathtub 2 is provided in the one side of the floor, and the other side becomes the washroom 3. As shown in FIG. An exhaust port 5 is provided in a portion of the ceiling 4 on the bathtub 2 side, and an exhaust fin 6 is provided immediately above the exhaust port 5. The exhaust fin 6 communicates with an exhaust pipe 104 of the house 101. Yes. As a result, the exhaust port 5 communicates with the outside of the house 101 through the exhaust fins 6 and the exhaust pipe 104.

  On the other hand, an inspection port 7 is provided in a portion of the ceiling 4 on the washing room 3 side. The inspection port 7 is used when inspecting functional members such as the exhaust fins 6 arranged on the bathroom unit 1. The size of the inspection port 7 may be a size that allows the inspection operator to get on the upper body, and is, for example, a square having a horizontal dimension of 450 mm and a vertical dimension of 450 mm. Furthermore, an inspection port lid 8 is provided in the inspection port 7 so as to be detachable from the inspection port 7. The inspection port lid 8 is a panel-like member that is fitted to the inspection port 7 during normal use and closes the inspection port 7, and is removed from the inspection port 7 during inspection to open the inspection port 7.

  As shown in FIGS. 3 to 5, for example, a circular opening is formed as the light emission port 11 in the center region of the inspection port lid 8. A bracket 13 is attached immediately below the light emission port 11 on the lower surface of the inspection port lid 8. The bracket 13 is a member made of a translucent material that transmits light while diffusing, for example, a milky white resin material, and has a dome-shaped portion that is arranged so as to protrude downward. Further, a light emission port member 14 is provided on the inspection port lid 8. The light emission port member 14 is attached to the inspection port lid 8, and is thereby fixed to the light emission port 11.

  The light emission port member 14 is a duct made of a light shielding body, and its inner surface is a light reflecting surface. The light reflecting surface is, for example, a mirror surface or a white surface, and is configured by, for example, a metal surface such as aluminum or stainless steel, or a surface in which a coating layer such as aluminum oxide or resin is laminated on the surface of these metal surfaces. . The shape of the cross section perpendicular to the axis of the light emission port member 14 is, for example, a rectangle. The light emission port member 14 once extends upward in the vertical direction from the light emission port 11, then bends at a right angle, and then extends in the horizontal direction and terminates. The terminal portion is open and serves as a light entrance 15.

In other words, the light emission port member 14 includes, for example, a rectangular columnar vertical portion 14a extending upward from the light emission port 11, and a horizontal columnar shape 14b extending in the horizontal direction from the upper end of the vertical portion 14a. And the end of the horizontal portion 14b that is not coupled to the vertical portion 14a is a light incident port 15.
In the present specification, the terms “vertical”, “horizontal”, and “right angle” include substantially vertical, substantially horizontal, and substantially right angle, respectively.

  Further, the side surface 14c of the bent portion between the vertical portion 14a and the horizontal portion 14b is inclined at such an angle that the light transmitted through the horizontal portion 14b is reflected toward the vertical portion 14a. A light transmitting plate 16 is attached to the light incident port 15. The translucent plate 16 is made of, for example, a transparent resin, and hermetically closes the light incident port 15.

  On the other hand, the front end of the light duct 102 on the bathroom unit 1 side extends downward and then bends in the horizontal direction, and the front end surface opens in the horizontal direction to form a light emission port 105. . That is, the light exit port 105 is inclined with respect to a horizontal plane, for example, a vertical plane. A light transmitting plate 106 is attached to the light exit port 105. The translucent plate 106 is made of, for example, a transparent resin, and hermetically closes the light exit port 105. Further, the side surface of the bent portion of the optical duct 102 is inclined at such an angle that the light transmitted from above in the optical duct 102 is reflected toward the light exit port 105.

  The light incident port 15 of the light emission port member 14 faces the light emitting port 105 of the optical duct 102. That is, the translucent plate 16 attached to the light incident port 15 is disposed substantially parallel to the translucent plate 106 attached to the light exit port 105 and is separated by a gap c. For this reason, the light emission port member 14 is not connected to the optical duct 102. Further, the light emission port member 14 is disposed in a region outside the region directly below the light emission port 105. The size of the gap c is, for example, several centimeters. The size of the gap c between the translucent plate 16 and the translucent plate 106 is not particularly limited. However, when the inspection port lid 8 is attached to and detached from the inspection port 7 together with the light emission port member 14, the light emission port member 14. Is so small that it does not contact the light duct 102 and small enough that the light transmission efficiency from the light exit port 105 to the light entrance port 15 is not significantly reduced.

  On the other hand, at the edge of the inspection port 7, the lower surface side portion protrudes toward the inside of the inspection port 7 rather than the upper surface side portion, and therefore the lower surface side is convex at the edge of the inspection port 7. A step 7a is formed. On the other hand, the upper surface side portion of the inspection port lid 8 is slightly larger than the lower surface side portion, and the outer edge of the upper surface side portion is outside the outer edge of the lower surface side portion when viewed from the direction perpendicular to the surface of the inspection port lid 8. On the side surface of the inspection port lid 8, a step 8a having a convex upper surface is formed. When the inspection port lid 8 is attached to the inspection port 7, the step 8 a of the inspection port lid 8 is engaged with the step 7 a of the inspection port 7, and the inspection port lid 8 is held inside the inspection port 7. Yes. An annular packing 9 is fitted into a portion of the step 7a that contacts the step 8a.

  As shown in FIG. 4, the bracket 13 includes a substantially hemispherical dome-shaped portion 13a, an annular plate-shaped portion 13b extending from the outer edge of the dome-shaped portion 13a toward the center, and an annular plate. A cylindrical portion 13c erected in a direction away from the inner edge portion of the shaped portion 13b with respect to the dome-shaped portion 13a is integrally formed. The dome-shaped portion 13 a protrudes downward from the ceiling 4. A screw groove 13d is formed on the outer surface of the cylindrical portion 13c. On the other hand, a screw groove 8d that is screwed into the screw groove 13d is formed at the lower part of the inner surface of the light emission port 11 in the inspection port cover 8. An annular packing 10 is provided on the upper end portion of the bracket 13. The bracket 13 is fixed to the inspection port lid 8 together with the packing 10 by screwing the screw groove 13 d into the screw groove 8 d of the inspection port lid 8.

Next, the operation of the bathroom unit according to this embodiment will be described.
First, the operation of the bathroom unit 1 during normal use will be described.
As shown in FIG. 1, the inspection port lid 8 is attached to the inspection port 7 during normal use of the bathroom unit 1. At this time, the light incident port 15 of the light emitting port member 14 is disposed at a position close to the light emitting port 105 of the optical duct 102 and is opposed to the light emitting port 105, but is not in contact with it. For this reason, the light emission port member 14 is optically coupled to the optical duct 102 but is not mechanically coupled.

  In this state, as shown in FIG. 1, external light L, for example, sunlight is introduced from the outside of the house 101 into the light duct 102 through the daylighting unit 103. The outside light L is transmitted through the light duct 102 while being repeatedly reflected by the inner surface of the light duct 102, passes through the light transmitting plate 106, and is emitted from the light emitting port 105 at the most advanced portion. The external light L emitted from the light emission port 105 passes through the gap c and reaches the light incident port 15 of the light emission port member 14. Then, the light is transmitted through the light transmitting plate 16 and introduced into the light emitting port member 14 from the light incident port 15. Thereafter, the external light L is guided to the light emission port 11 by appropriately reflecting on the inner surface of the light emission port member 14. The external light L that has reached the light emission port 11 is diffused by passing through the dome-shaped portion 13 a of the bracket 13, and is diffused radially into the bathroom unit 1. On the other hand, when the exhaust fin 6 is driven, the air in the bathroom unit 1 is exhausted to the outside of the building through the exhaust port 5 and the exhaust pipe 104.

Next, the operation at the time of checking the bathroom unit 1 will be described.
As shown in FIG. 3, when inspecting a functional member disposed on the ceiling 4 of the bathroom unit 1, such as the exhaust fin 6, for example, after removing the bracket 13 from the inspection port lid 8, the inspection port lid 8 is removed. Once lifted upward, it is removed from the inspection port 7 together with the light emission port member 14, then transported in the horizontal direction, and temporarily placed in an area other than the inspection port 7 on the ceiling 4. Thereby, the inspection port 7 is opened, and an operator (not shown) can perform the inspection work through the inspection port 7. After the inspection work is completed, the inspection port lid 8 is attached to the inspection port 7 together with the light emission port member 14 and the bracket 13 is attached.

Next, the effect of this embodiment will be described.
In this embodiment, since the light emission port 11 is provided in the inspection port lid 8 of the inspection port 7, it is not necessary to provide a light emission port separately from the inspection port 7 on the ceiling 4 of the bathroom unit 1. For this reason, even if the light emission port 11 is provided, the space on the ceiling 4 is not compressed, the degree of freedom of arrangement of the functional member is not lowered, and the maintainability of the functional member is not lowered. Moreover, the external appearance of the ceiling 4 seen from the bathroom unit 1 is refreshed.

  Further, since the light emission port member 14 is not connected to the light duct 102, when the inspection port cover 8 is attached to or detached from the inspection port 7, an attaching / detaching operation between the light emission port member 14 and the light duct 102 is unnecessary. It is. For this reason, the inspection lid 8 can be removed from the inspection port 7 simply by lifting the inspection port lid 8. Therefore, the bathroom unit 1 according to the present embodiment has excellent maintainability of the functional member. Further, since the light exit port 105 is inclined with respect to the horizontal plane, and the light exit member 14 is disposed in a region outside the region directly below the light exit port 105 of the light duct 102, the light exit member 14. Is not restricted from moving upward. In particular, in the present embodiment, since the light exit port 105 forms a vertical surface, the size of the gap c is set while disposing the light emitting port member 14 in a region outside the region directly below the light exit port 105. It can be made as small as possible.

  Furthermore, the bathroom unit 1 according to the present embodiment can be realized by providing the light emission port member 14 with respect to the existing bathroom unit and changing the design of the inspection port lid 8. For parts other than the palate 8, existing parts can be used as they are. For this reason, the increase in cost by providing a light emission port can be suppressed.

  Furthermore, in the present embodiment, when the bathroom unit 1 is inspected, the inspection port lid 8 can be temporarily placed together with the light emission port member 14 at an arbitrary location on the ceiling 4. That is, depending on the contents of the inspection work, the inspection mouth cover 8 and the light emission opening member 14 need only be placed in a place where they do not interfere with the inspection work. There is almost no hindrance and maintenance is high. On the other hand, when the light emission port is fixedly provided on the ceiling 4, the position of the light emission port member coupled to the light emission port is also fixed. The light emission member obstructs the work.

  Furthermore, since the light incident port 15 of the light emission port member 14 is provided with the light transmitting plate 16, the inside of the light emission port member 14 can be hermetically sealed. Thereby, it is possible to prevent dust and insects from entering the light emitting port member 14 and reducing the light use efficiency. Further, since the packing 10 is provided on the bracket 13, the vapor in the bathroom unit 1 may enter the light emission port member 14 to fog or corrode the inner surface of the light emission port member 14. Can be prevented.

  On the other hand, since a light transmitting plate 106 is provided at the light exit port 105 of the light duct 102, dust, insects, water vapor, and the like do not enter the light duct 102, and the light utilization efficiency in the light duct 102 is reduced. Will not drop. Further, since the packing 9 is provided on the surface of the inspection port 7 that contacts the inspection port lid 8, the airtightness between the inspection port 7 and the inspection port lid 8 is high, and the water vapor in the bathroom unit 1 is on the ceiling 4. Will not leak. For this reason, the translucent plates 16 and 106 are clouded by the water vapor leaked from the bathroom unit 1, and the light transmission efficiency is not lowered.

  In the present embodiment, the example in which the shape of the light emitting port member in the cross section perpendicular to the axis is rectangular is shown, but the present invention is not limited to this, and the shape of the cross section may be, for example, a circle. That is, the light emission port member may be formed by combining cylindrical ducts.

  Moreover, the inspection opening lid 8 and the bracket 13 may be integrally formed using two kinds of resin materials, ie, a light-impermeable material and a light-transmissive material. In this case, the integrally molded product becomes a two-color molded body, and a portion corresponding to the inspection port lid 8 is formed of the light-impermeable material, and a portion corresponding to the bracket 13 is formed of the light-transmitting material. At the time of inspection, the integrally molded product is once lifted upward from the inspection port 7, then transported in the horizontal direction, and temporarily placed in an area other than the inspection port 7 on the ceiling 4. In this way, the structure of the inspection port lid 8 and the bracket 13 is simplified, and the packing 10 is not necessary. Note that the lower surface of the integrally molded product may be flat. Thereby, temporary placement becomes easy. Moreover, you may form the inspection opening lid 8 whole with a translucent material. Thereby, a portion corresponding to the bracket 13 can be omitted.

Hereinafter, modifications of the above-described embodiment will be described. The following modifications are variations on the shape and the positional relationship of the light emission port member and the optical duct.
First, a first modification will be described.
FIG. 6 is a cross-sectional view illustrating the vicinity of a light emission port member of a bathroom unit according to this modification.
FIG. 7 is a cross-sectional view illustrating a coupling member of the bathroom unit.
As shown in FIG. 6, in this modified example, the horizontal portion is not provided in the light emission port member 24 as compared with the above-described embodiment, and the light emission port member 24 and the optical duct 102 are coupled. The difference is that the member 25 is provided.

  That is, the shape of the light emission port member 24 of this modification is a quadrangular prism shape with the upper surface inclined. A light incident port 15 is formed on the side surface of the upper end portion of the light emitting port member 24, and a light transmitting plate 16 is attached to the light incident port 15. Further, a coupling member 25 is connected to the light transmitting plate 16. The coupling member 25 is a cylindrical duct having both ends opened, the central axis extends in the horizontal direction, and the inner surface is a light reflecting surface. One end of the coupling member 25 is connected to the translucent plate 16 and is optically coupled to the light incident port 15 of the light emission port member 24.

  On the other hand, the other end of the coupling member 25 faces the light exit port 105 of the optical duct 102 and is optically coupled to the light exit port 105. However, the other end of the coupling member 25 is not in contact with the optical duct 102, and a gap c is formed between the coupling member 25 and the translucent plate 106 attached to the optical duct 102. For this reason, the coupling member 25 is not mechanically connected to the optical duct 102. In addition, as shown in FIG. 7, the shape of the end surface of the coupling member 25 is annular, the shape of the light emission port 105 is rectangular, and both shapes are different from each other. Further, the inner edge of the end face of the coupling member 25 is disposed inside the outer edge of the light exit port 105.

  In this modification, the light emitted from the light exit port 105 of the light duct 102 is introduced into the coupling member 25 through the gap c, transmitted through the coupling member 25, and then via the light incident port 15. The light enters the light emission port member 24, transmits through the light emission port member 24, and reaches the light emission port 11.

Next, the effect of this modification will be described.
When the bathroom unit 1 is actually installed in a building, the position from which the front end of the light duct 102 is drawn may differ depending on the building, and the light emission port provided in the inspection port lid 8 of the bathroom unit 1 11 and the light exit port 105 of the light duct 102 may not be constant. In the above-described embodiment, in such a case, it is necessary to individually design the light emission port member according to the positional relationship between the light emission port 11 and the light emission port 105. On the other hand, according to this modification, if only the shape of the coupling member 25 is changed according to the positional relationship between the light emission port 11 and the light emission port 105, it is necessary to change the light emission port member. Rather, a light emission port member of the same standard can be used. Thereby, the installation cost of a bathroom unit can be reduced. Configurations, operations, and effects other than those described above in the present modification are the same as in the above-described embodiment.

Next, a second modification will be described.
FIG. 8 is a cross-sectional view illustrating the vicinity of a light emission port member of a bathroom unit according to this variation.
As shown in FIG. 8, in the present modification, the coupling member 25 (see FIG. 6) is omitted and the light emission port member 24 is connected to the optical duct 102 as compared with the first modification described above. Directly optically coupled. The light emitting port member 24 is not mechanically connected to the optical duct 102. Configurations other than those described above in the present modification are the same as those in the first modification described above.

  As shown in this modification, when the optical duct 102 can be pulled out to the vicinity of the region directly above the light emission port 11, the coupling member can be omitted. Thereby, compared with the above-mentioned 1st modification, although inspection work efficiency falls somewhat, while reducing cost, the utilization efficiency of light can be improved. Operations and effects other than those described above in the present modification are the same as those in the above-described embodiment.

Next, a third modification will be described.
FIG. 9 is a cross-sectional view illustrating the vicinity of a light emission port member of a bathroom unit according to this variation.
As shown in FIG. 9, in this modification, the optical duct 102 is disposed so as to extend in the horizontal direction, the distal end portion is not bent, and the light emission port 105 opens in the horizontal direction. ing. Also in this case, the same effect as that of the second modified example can be obtained.

Next, a fourth modification will be described.
FIG. 10 is a cross-sectional view illustrating the vicinity of the light emission port member of the bathroom unit according to this variation.
As shown in FIG. 10, in the present modification, the shape of the light emission port member 34 is a continuously curved curved tube. That is, the light emission port member 34 is continuously bent while being drawn upward from the light emission port 11 of the inspection port lid 8, and is directed toward the light emission port 105 of the light duct 102. The light incident port 15 formed at the end of the light emission port member 34 faces the light emitting port 105 with a gap c therebetween. Configurations, operations, and effects other than those described above in the present modification are the same as in the above-described embodiment.

Next, a fifth modification will be described.
FIG. 11 is a cross-sectional view illustrating the vicinity of the light emission port member of the bathroom unit according to this variation.
As shown in FIG. 11, in the present modification, the front end portion of the optical duct 102 extends in the vertical direction, and the light emission port 105 opens downward. On the other hand, the light emission port member 44 is not bent, and the light incident port 15 of the light emission port member 44 is disposed immediately below the light emission port 105 of the light duct 102 and opens upward. Yes. The distance h between the light exit port 105 and the light entrance port 15 is such that the inspection port lid 8 can be attached to and detached from the inspection port 7 and the inspection operator can get out of the upper body from the inspection port 7. For example, several tens of centimeters.

  If there is a sufficient distance between the ceiling of the bathroom unit and the ceiling of the house 101 and the light transmission efficiency from the light exit port 105 to the light entrance port 15 may be somewhat low, It is possible to adopt a configuration. According to this modification, since the structure of the light emission port member 44 can be simplified, the cost can be reduced, and the light emission port member can be reduced in weight, so that the inspection port lid 8 can be easily attached and detached. it can. Configurations, operations, and effects other than those described above in the present modification are the same as those in the above-described embodiment.

  The features of the present invention have been described above with reference to the embodiment of the present invention and its modifications. However, the present invention is not limited to these embodiments and modifications. That is, even if a person skilled in the art appropriately adds, omits, or changes a design for any element constituting the bathroom unit according to the above-described embodiment or modification, the element of the present invention is included.
