Description

  Aspects of the present invention generally relate to an illuminated bathtub apparatus, and more specifically to an illuminated bathtub apparatus that can illuminate the interior of the bathtub using illumination.

  In order to enhance the design of the bathtub and enhance the production effect, there is a bathtub with a lighting fixture attached in the vicinity of the bathtub. In such a bathtub, for example, a lighting device is attached to the back surface side of the bathtub, and a notch is provided in a part of the bathtub so that light from the lighting device is passed through the bathtub.

  Therefore, lighting that uses a bathtub in which a transparent layer, a decorative layer, and a reinforcing layer are formed on a laminate, forms a notch only in the decorative layer and the reinforcing layer, and is attached to the back side of the bathtub There is an effect lighting device for a bathtub that can shine the light of the instrument through the transparent layer in the bathtub (Patent Document 1). However, in the apparatus described in Patent Document 1, a light source is arranged circumferentially on the outer side (back surface side) of the bathtub, and light is emitted when a portion of the height direction of the bathtub is intended to shine circumferentially. There is a risk that the brightness of the boundary between the part and the part that does not shine will appear clearly.

This is because the distance between the bathtub and the reflecting member is substantially constant on the vertical line on the rear surface of the light-transmitting bathtub, so that the amount of light incident on the portion covered by the reflecting member of the bathtub is uniform. is there. The gradation effect cannot be enhanced if the borders are bright and dark, and the design of the bathtub is not good.

Moreover, 3rd invention is 1st or 2nd invention, The said reflector is a horizontal part extended in a horizontal direction in the boundary part vicinity of the bottom face part and side part of the said bathtub, The said horizontal part A vertical portion extending in a direction substantially orthogonal to the horizontal portion, and the horizontal portion decreases the distance from the bottom surface portion in the perpendicular direction of the bottom surface of the bottom surface in a vertical sectional view as the distance from the light source increases. The vertical portion is arranged so that the distance from the side surface portion in the perpendicular direction of the back surface of the side surface portion in a vertical cross-sectional view decreases as the distance from the light source increases. This is an illuminated bathtub device.
According to this illuminated bathtub device, the light emitted from the light source can be more reliably reflected toward the bathtub.

Embodiments of the present invention will be described below with reference to the drawings. In addition, in each drawing, the same code | symbol is attached | subjected to the same component and detailed description is abbreviate | omitted suitably.
FIG. 1: is the upper surface schematic diagram which looked at the bathtub apparatus with illumination concerning embodiment of this invention from upper direction.
Moreover, FIG. 2 is the side surface schematic diagram which looked at the bathtub apparatus with illumination concerning this embodiment from the side.

  The bathtub apparatus with illumination according to the present embodiment is capable of storing bathtub water, and at least a part of the bathtub 10 has translucency, and connected light sources 20a and 20b having a plurality of light sources that emit light, and the connection thereof. Guide members 30a and 30b that respectively hold the light sources 20a and 20b, and a reflector 42 that is provided around the connected light sources 20a and 20b and reflects the light emitted from the connected light sources 20a and 20b toward the bathtub 10. I have.

  In the specification of the present application, “translucent” means that light from a coupled light source is transmitted with almost no reflection or absorption, or even if light from a coupled light source is partially absorbed or reflected. The property which can be transmitted to the inside of the bathtub 10 (the side where the bathtub water can be stored and the user can enter it). Further, in the present specification, the term “water” includes not only cold water but also heated hot water.

  The illuminated bathtub device according to the present embodiment further includes a power supply unit 62 and a power switch 64. As shown in FIG. 1, the power switch 64 is connected to an external power source. The coupled light sources 20a and 20b are connected to an external power source via a power source 62 and a power switch 64. The user can turn on or off the connected light sources 20a and 20b by switching the power switch 64.

  The coupled light sources 20a and 20b, the guide members 30a and 30b, and the reflector 42 are arranged outside the bathtub 10 and in the lower part thereof as shown in FIG. In addition, as illustrated in FIG. 1, the connection light source 20 a and the guide member 30 a are disposed on the bottom surface portion 11 of the bathtub 10 and the front portion of the side surface portion 12. On the other hand, the connection light source 20b and the guide member 30b are arrange | positioned at the back part of the bottom face part 11 of the bathtub 10, and the side part 12, and the left-right side part. And the connection light sources 20a and 20b and the guide members 30a and 30b are arrange | positioned by the circumferential shape so that at least any one of the bottom face part 11 and the side part 12 of the bathtub 10 may be surrounded as a whole.

  Therefore, the connected light sources 20 a and 20 b can shine the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10 from the outside of the bathtub 10 in a circumferential shape. However, the installation form of the connected light sources 20a, 20b, the guide members 30a, 30b, and the reflector 42 is not limited to the installation form shown in FIG. 2 and is outside the bathtub 10 and in the vicinity of the center in the vertical direction. It may be. According to this, the connection light sources 20a and 20b can shine only the side surface part 12 of the bathtub 10 from the outer side of the bathtub 10 in the circumferential shape. This will be described in detail later with respect to FIG.

  Since the bathtub 10 has translucency, the coupled light sources 20 a and 20 b can shine the inside of the bathtub 10 through the bathtub 10. In addition, the connection light source and the guide member do not need to be divided into a plurality as shown in FIG. For example, the connected light source and the guide member are each composed of one member, and the connected light source and the guide member are circumferentially arranged so as to surround at least one of the bottom surface portion 11 and the side surface portion 12 of the bathtub 10. Also good.

  Thus, in order to transmit light from the outside of the bathtub 10 and to brighten the inner surface (inner surface) of the bathtub 10 brighter or more efficiently, the reflector 42 is disposed around the coupled light sources 20a and 20b. It is preferable to do. According to this, the connection light sources 20a and 20b can be spaced apart from the bathtub 10 and arrange | positioned. Therefore, there is little possibility that the light sources of the connected light sources 20a and 20b are substantially pointed, and the inner surface of the bathtub 10 can be made more uniform and shine.

  A support 50 that supports the bathtub 10 is provided in a lower portion of the bathtub 10. Moreover, the outer peripheral wall (apron) 55 which hides the outer surface 13 of the side part 12 of a bathtub, or hides the support body 50 and improves the design property of an illuminated bathtub apparatus is provided around the bathtub 10. The outer peripheral wall 55 is provided with openings 56a and 56b through which the connecting light sources 20a and 20b can be attached / detached.

  FIG. 3 is a schematic diagram for explaining an intensity distribution of light emitted from a light source and transmitted through a bathtub. FIG. 3A is a schematic diagram for explaining the light intensity distribution when the reflector of the comparative example is attached, and FIG. 3B is an example of the reflector according to the present embodiment. It is a schematic diagram for demonstrating the intensity distribution of light when is attached.

  First, as shown in FIG. 3A, consider a comparative example in which a light source 23 is provided on the outer surface 13 side of the bathtub 10 and a reflector 42 a is provided around the light source 23. The reflector 42a of the comparative example has a substantially straight shape on each side, and has a side substantially perpendicular to the outer surface 13 and a side substantially parallel to the outer surface 13. A side portion substantially orthogonal to the outer surface 13 is attached to the outer surface 13 of the bathtub 10. A substantially rectangular space exists in a portion surrounded by the reflector 42 a and the bathtub 10. Therefore, the distance between the outer surface 13 and the inner surface of the reflector 42 a on a straight line (hereinafter referred to as “perpendicular”) perpendicular to the outer surface (back surface) 13 of the bathtub 10 is from the light source 23 even if it is near the light source 23. It is substantially the same even at a remote location.

  The light emitted from the light source 23 is directly incident on the outer surface 13. Alternatively, the light emitted from the light source 23 is indirectly incident on the outer surface 13 by being irregularly reflected by the reflector 42a even if it is not directly incident. When the light emitted from the light source 23 enters the outer surface 13 directly or indirectly, the bathtub 10 has translucency, so that the side surface portion 12 of the bathtub 10 can shine.

  At this time, as shown in FIG. 3A, the light intensity distribution is substantially uniform in the side surface portion 12 of the portion surrounded by the reflector 42 a and the bathtub 10. And the intensity | strength of the light in the side part 12 is large, and the side part 12 shines brightly. However, in the vicinity of the boundary between the portion surrounded by the reflector 42a and the bathtub 10 and the portion not surrounded, the light intensity rapidly decreases. This is because the side portion attached to the outer surface 13 is substantially orthogonal to the outer surface 13. More specifically, the distance between the outer surface 13 and the inner surface of the reflector 42a on the perpendicular of the outer surface 13 is substantially the same at a predetermined distance inside the reflector 42a, but suddenly becomes zero outside the reflector 42a. It is to become.

  Therefore, in the vicinity of the boundary between the portion surrounded by the reflector 42a and the bathtub 10 and the portion not surrounded, there is a possibility that the brightness of the side surface portion 12 becomes clear. Thus, when the brightness of the side surface portion 12 becomes clear, the gradation effect of the side surface portion 12 cannot be enhanced.

  On the other hand, as shown in FIG. 3B, consider an example of the present embodiment in which the light source 23 is provided on the outer surface 13 side of the bathtub 10 and the reflector 42 b is provided around the light source 23. The reflector 42b as an example of this embodiment has a curved portion. The distance between the outer surface 13 and the inner surface of the reflector 42b on the perpendicular of the outer surface (back surface) 13 is large in the vicinity of the light source 23, and decreases as the distance from the light source 23 increases.

  The light emitted from the light source 23 enters the outer surface 13 directly or indirectly as described above. And when the light discharge | released from the light source 23 injects into the outer surface 13, since the bathtub 10 has translucency, the side part 12 of the bathtub 10 can shine.

  At this time, as shown in FIG. 3B, the intensity of light in the vicinity of the light source 23 is the highest in the side surface portion 12 surrounded by the reflector 42b and the bathtub 10, and the side surface portion 12 shines brightly. . And while separating from the light source 23, the intensity | strength of light becomes small and the side part 12 becomes dark gradually. That is, the light / dark boundary of the side surface portion 12 is not clear and is blurred.

  When the distance between the outer surface 13 on the perpendicular to the outer surface 13 and the inner surface of the reflector 42b is large as in the vicinity of the light source 23, the light irregularly reflected by the reflector 42b enters the bathtub 10 from various angles. This is because it is easy. On the other hand, when the distance between the outer surface 13 on the perpendicular to the outer surface 13 and the inner surface of the reflector 42b is small, such as a position away from the light source 23, the light irregularly reflected by the reflector 42b is difficult to enter the bathtub 10. It is.

  As described above, the distance between the outer surface 13 and the inner surface of the reflector 42b on the vertical line of the outer surface 13 is large in the vicinity of the light source 23, and is separated from the light source 23 and is small so that the reflector 42b and the bathtub 10 are surrounded. The amount of light incident on the bathtub 10 in the portion can be changed. According to this, the brightness in the vicinity of the boundary between the part surrounded by the reflector 42b and the bathtub 10 and the part not enclosed is not clear. Therefore, the side part 12 of the bathtub 10 can be lit with a gradation that gradually darkens as the distance from the light source 23 increases. That is, the gradation effect of the side part 12 of the bathtub 10 can be enhanced.

Next, a specific example of the installation form of the connection light source and the reflector will be described with reference to the drawings.
FIG. 4 is a schematic cross-sectional view for explaining a specific example of the installation form of the connection light source and the reflector, and corresponds to the AA cross-sectional view shown in FIG. 1.

  First, the bottom part 11 and the side part 12 of the bathtub 10 are demonstrated, referring drawings. A straight line perpendicular to the tangent at that point, that is, a normal line, is considered at one point on the inner surface of the bathtub 10 capable of storing bathtub water. Further, consider a normal that forms an angle of 45 degrees with the horizontal direction. The bathtub 10 on the upper side of the normal line forming an angle of 45 degrees with the horizontal direction is referred to as a “side surface portion 12” in the present specification. On the other hand, the bathtub 10 on the lower side of the normal line forming an angle of 45 degrees with the horizontal direction is referred to as a “bottom surface portion 11” in the present specification.

  Similar to the reflector 42b shown in FIG. 3, the reflector 42c of this specific example has a curved portion (curved portion) in the vertical sectional view (vertical sectional view) as shown in FIG. Yes. The reflector 42 c is attached to the outer surface 13 of the side surface portion 12 via sealing bodies 44 and 45. The guide member 30a is fixed to the reflector 42c by a fixing member 48. The guide member 30a is fixed at a position where the distance between the outer surface 13 and the inner surface of the reflector 42c on the perpendicular to the outer surface 13 is substantially maximum. And the connection light source 20a is inserted and hold | maintained inside the guide member 30a so that it may explain in full detail behind. Therefore, the distance between the outer surface 13 and the inner surface of the reflector 42c on the perpendicular of the outer surface (back surface) 13 is large in the vicinity of the coupled light source 20a and is separated from the coupled light source 20a in a vertical sectional view as shown in FIG. Get smaller.

  The light emitted from the coupled light source 20a is incident on the outer surface 13 directly or indirectly as described above. And when the light discharge | released from the connection light source 20a injects into the outer surface 13, since the bathtub 10 has translucency, the side part 12 of the bathtub 10 can shine.

  At this time, the distance between the outer surface 13 and the inner surface of the reflector 42c on the vertical line of the outer surface 13 decreases as the distance from the connection light source 20a decreases, so that the reflector 42c, the sealing bodies 44 and 45, and the bathtub 10 are surrounded. The amount of light incident on the bathtub 10 (side surface portion 12) in the portion can be changed. Thereby, the side part 12 becomes dark gradually as it separates from the connection light source 20a. That is, in this specific example, the side surface portion 12 of the bathtub 10 can be illuminated with a gradation that gradually becomes darker as the distance from the connected light source 20a increases.

  Moreover, since the connection light sources 20a and 20b and the guide members 30a and 30b are circumferentially arranged so as to surround at least one of the bottom surface portion 11 and the side surface portion 12 of the bathtub 10, as described above with reference to FIG. Only the side surface portion 12 can be illuminated in a circumferential shape. Therefore, in the bathtub apparatus with illumination according to this example, the gradation effect of the side surface portion 12 of the bathtub 10 can be enhanced in a circumferential shape. In the schematic cross-sectional view shown in FIG. 4, the structure around the coupled light source 20a and the guide member 30a has been described, but the structure around the coupled light source 20b and the guide member 30b also has the same structure. .

FIG. 5 is a schematic cross-sectional view for explaining another specific example of the installation form of the connection light source and the reflector, and corresponds to the AA cross-sectional view shown in FIG. 1.
As shown in FIG. 5, the reflector 42 d of this specific example has a horizontal portion 42 i extending in the horizontal direction and a horizontal portion 42 i in the vicinity of the boundary portion between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10. And a vertical portion 42j extending in a substantially orthogonal direction. The reflector 42d is fixed to the support 50 as appropriate. Further, the vertical portion 42 j of the reflector 42 d is attached to the outer surface 13 of the side surface portion 12 via the sealing body 44. Further, the horizontal portion 42 i of the reflector 42 d is attached to the outer surface 14 of the bottom surface portion 11 via the sealing body 45.

  The guide member 30a is fixed by the fixing member 48 in the vicinity of the boundary portion between the horizontal portion 42i and the vertical portion 42j of the reflector 42d. And the connection light source 20a is inserted and hold | maintained inside the guide member 30a so that it may explain in full detail behind. Therefore, the distance between the outer surfaces 13 and 14 and the inner surface of the reflector 42d on the normal of the outer surfaces (back surfaces) 13 and 14 is the connected light source 20a in the vertical sectional view (vertical sectional view) as shown in FIG. It is large in the vicinity and becomes small as it is separated from the connected light source 20a.

  The light emitted from the coupled light source 20 a is directly or indirectly incident on the outer surfaces 13 and 14 in the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10. And when the light discharge | released from the connection light source 20a injects into the outer surfaces 13 and 14, since the bathtub 10 has translucency, the boundary part vicinity of the bottom face part 11 and the side part 12 of the bathtub 10 can shine.

  At this time, the distance between the outer surfaces 13 and 14 and the inner surface of the reflector 42d on the vertical line of the outer surfaces 13 and 14 decreases as the distance from the connection light source 20a decreases, so the reflector 42d, the sealing bodies 44 and 45, and the bathtub 10 The amount of light incident on the bathtub 10 (the side surface portion 12 and the bottom surface portion 11) in the portion surrounded by can be changed. As a result, the side surface portion 12 and the bottom surface portion 11 gradually become darker as they are separated from the connected light source 20a. That is, in this specific example, the vicinity of the boundary portion between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10 can be illuminated with a gradation that gradually darkens as the distance from the connected light source 20a increases.

  Moreover, since the connection light sources 20a and 20b and the guide members 30a and 30b are circumferentially arranged so as to surround at least one of the bottom surface portion 11 and the side surface portion 12 of the bathtub 10, as described above with reference to FIG. The vicinity of the boundary portion between the bottom surface portion 11 and the side surface portion 12 can be illuminated in a circumferential shape. Therefore, in the illuminated bathtub device according to this example, the gradation effect in the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12 can be enhanced circumferentially. In the schematic cross-sectional view shown in FIG. 5, the structure around the coupled light source 20a and the guide member 30a has been described, but the structure around the coupled light source 20b and the guide member 30b also has the same structure. .

FIG. 6 is a schematic cross-sectional view for explaining still another specific example of the configuration of the connection light source and the reflector, and corresponds to the AA cross-sectional view shown in FIG.
Like the reflector 42d shown in FIG. 5, the reflector 42e of this specific example has a horizontal portion 42i extending in the horizontal direction in the vicinity of the boundary portion between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10, and its And a vertical portion 42j extending in a direction substantially orthogonal to the horizontal portion 42i. The reflector 42 e is appropriately fixed to the support body 50 and attached to the outer surface 14 of the bottom surface portion 11 via the sealing body 45. The reflector lid 41 is appropriately fixed to the upper part of the reflector 42 and is attached to the outer surface 13 of the side surface portion 12 via the sealing body 44. The reflector lid 41 has translucency.

  The guide member 30a is fixed by the fixing member 48 in the vicinity of the boundary portion between the horizontal portion 42i and the vertical portion 42j of the reflector 42e. And the connection light source 20a is inserted and hold | maintained inside the guide member 30a so that it may explain in full detail behind. Therefore, the distance between the outer surfaces 13 and 14 and the inner surface of the reflector 42d on the vertical line of the outer surfaces (back surfaces) 13 and 14 is the connected light source 20a in the vertical sectional view (vertical sectional view) as shown in FIG. It is large in the vicinity and becomes small as it is separated from the connected light source 20a. About another structure, it is the same as that of the structure of the bathtub apparatus with illumination concerning the specific example represented to FIG.

  In this specific example, since the reflector lid 41 having translucency is provided above the reflector 42e, the light emitted from the connected light source 20a is transmitted through the reflector lid 41 and thus the side surface portion 12. It can inject into the outer surface 13 of the center part vicinity of the up-down direction. Therefore, the light emitted from the connected light source 20a can shine not only in the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12 of the bathtub 10 but also in the vicinity of the central portion in the vertical direction of the side surface portion 12 with gradation. it can.

  Since the connection light sources 20a and 20b and the guide members 30a and 30b are arranged in a circumferential shape so as to surround at least one of the bottom surface portion 11 and the side surface portion 12 of the bathtub 10, as described above with reference to FIG. The vicinity of the boundary between the part 11 and the side part 12 and the vicinity of the central part in the vertical direction of the side part 12 can be illuminated in a circumferential shape. Therefore, in the illuminated bathtub device according to this example, the gradation effect in the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12 and in the vicinity of the center portion in the vertical direction of the side surface portion 12 can be enhanced in a circumferential shape. In the schematic cross-sectional view shown in FIG. 5, the structure around the coupled light source 20a and the guide member 30a has been described, but the structure around the coupled light source 20b and the guide member 30b also has the same structure. .

Next, specific examples of the coupled light source and the guide member will be described by taking the coupled light source, guide member, and reflector shown in FIGS. 5 and 6 as examples.
FIG. 7 is a schematic diagram for explaining a specific example of the coupled light source and the guide member, and is a schematic diagram illustrating a state before the coupled light source is inserted into the guide member.
FIG. 8 is a schematic diagram showing a state after the connection light source according to this example is inserted into the guide member.
For convenience of explanation, the connection light source 20a and the guide member 30a will be described below, but the connection light source 20b and the guide member 30b have the same structure.

  The connection light source 20 a includes a connection body 22 a and a plurality of light sources 23. The connecting body 22a is made of, for example, an elastic body and has flexibility. Although the light source 23 is inflexible, since the light source 23 is arranged in the flexible coupling body 22a, the coupling body 22a between the light source 23 and the adjacent light source 23 can be bent. . Therefore, the connection light source 20a has flexibility as a whole. The light source 23 is preferably an LED (Light Emitting Diode). According to this, the lifetime of the light source 23 can be extended.

  As shown in FIG. 7, the guide member 30a is fixed by the fixing member 48 in the vicinity of the boundary between the horizontal portion 42i and the vertical portion 42j of the reflectors 42d and 42e. The reflectors 42d and 42e have holes 43. The hole 43 is provided through the reflectors 42d and 42e. The fixing member 48 passes through the hole 43 and fixes the guide member 30a and the reflectors 42d and 42e.

  The guide member 30a has a hollow shape and has an insertion portion 31a at one end. Moreover, the guide member 30a has translucency. And the guide member 30a has the guide member main body 37a and the coating layer 38a laminated | stacked on the inner surface (contact surface) 32a of the guide member main body 37a. The covering layer 38a is formed of a material having higher slidability than the guide member main body 37a. Examples of the material of the guide member body 37a include flexible vinyl chloride resin. On the other hand, examples of the coating layer 38a include a coating film of an olefin resin such as polyethylene.

  The cross-sectional area of the insertion portion 31a perpendicular to the longitudinal direction of the guide member 30a is larger than the cross-sectional areas of the coupling body 22a and the light source 23 perpendicular to the longitudinal direction of the coupled light source 20a. Therefore, the connection light source 20a can be inserted in the direction of the arrow from the insertion portion 31a of the guide member 30a. At this time, as illustrated in FIG. 1, the guide member 30 a is fixed to the reflectors 42 d and 42 e in a state where the guide member 30 a is disposed on the rear and left and right side portions of the bottom surface portion 11 and the side surface portion 12 of the bathtub 10. However, since the connection light source 20a has flexibility, it can move along the arrangement shape of the guide member 30a.

  Furthermore, since the coating layer 38a is provided on the inner surface 32a of the guide member main body 37a, the connection light source 20a can move smoothly on the inner surface 32a. As a result, the coupled light source 20a is inserted while smoothly moving on the inner surface 32a, and is housed inside the guide member 30a as shown in FIG. That is, the connected light source 20a is disposed in the vicinity of the boundary between the horizontal portion 42i and the vertical portion 42j of the reflectors 42d and 42e. And the light source 23 can irradiate light with this accommodation state. At this time, since the guide member 30a has translucency, the light emitted from the light source 23 passes through the guide member 30a and enters the outer surfaces 13 and 14 in the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12. it can. Therefore, the light source 23 can illuminate the vicinity of the boundary between the bottom surface 11 and the side surface 12 in a circumferential shape.

  Alternatively, in the specific example described above with reference to FIG. 6, the reflector lid 41 has translucency, and thus the light emitted from the light source 23 passes through the reflector lid 41 in the vicinity of the central portion in the vertical direction of the side surface portion 12. It can enter the outer surface 13. For this reason, the light source 23 can illuminate the vicinity of the central portion of the side surface portion 12 in the vertical direction.

  The guide member 30a shown in FIGS. 7 and 8 represents the insertion portion 31a side of one end for convenience of explanation, but has an insertion portion at the other end as well. Therefore, the connection light source 20a can be inserted and removed from the insertion portions at both ends of the guide member 30a. As shown in FIG. 2, the insertion portion at one end is disposed in the vicinity of the opening 56 a of the outer peripheral wall 55, and the insertion portion at the other end is disposed in the vicinity of the opening 56 b of the outer peripheral wall 55. And the opening parts 56a and 56b are provided toward the open space which is not a wall surface, for example. Therefore, the connection light source 20a can be easily attached or detached from the opening 56a or the opening 56b. Moreover, since the connection light source 20a can move an inner surface smoothly with the coating layer 38a, the connection light source 20a can be attached or detached more easily.

  Furthermore, since the connected light sources 20a and 20b and the guide members 30a and 30b are divided into a plurality of parts, the connected light sources 20a and 20b can be attached and detached more easily than a case where each of the connected light sources 20a and 20b is composed of one member. This is because the connection light source and the guide member have a long overall length when they are circumferentially arranged so as to surround at least one of the bottom surface portion 11 and the side surface portion 12 of the bathtub 10 by one member. This is because a light source needs to be attached or removed.

  Even when the connection light source 20a is attached or detached, the guide member 30a is fixed to the reflectors 42d and 42e. Moreover, it is preferable that the total length of the connection light source 20a is longer than the total length of the guide member 30a, and the total length of the connection light source 20b is longer than the total length of the guide member 30b. According to this, the vicinity of the boundary portion between the bottom surface portion 11 and the side surface portion 12 or the vicinity of the center portion in the vertical direction of the side surface portion 12 can be more reliably illuminated in a circumferential shape. That is, it is possible to prevent a portion that shines and a portion that does not shine in the vicinity of the boundary between the bottom surface portion 11 and the side surface portion 12 or in the vicinity of the center portion in the vertical direction of the side surface portion 12. Therefore, the design of the bathtub can be further improved, and the production effect can be further increased.

  As described above, according to the present embodiment, the distance between the outer surfaces 13 and 14 and the inner surfaces of the reflectors 42b, 42c, 42d, and 42e on the vertical line of the outer surfaces (back surfaces) 13 and 14 of the bathtub 10 is the connected light source. It is large in the vicinity of 20a (light source 23), and becomes small as it is separated from the connected light source 20a (light source 23). Therefore, the amount of light incident on the bathtub 10 in the portion surrounded by the reflector 42b and the bathtub 10 can be changed. Or the incident light quantity to the bathtub 10 in the part enclosed by the reflectors 42c, 42d, and 42e, the sealing bodies 44 and 45, and the bathtub 10 can be changed. Thereby, the gradation which becomes dark gradually as it leaves | separates from the connection light source 20a is attached, and the side part 12 of the bathtub 10, the boundary part vicinity of the bottom part 11 and the side part 12, or the upper and lower sides of the side part 12 The vicinity of the center of the direction can be illuminated. That is, the gradation effect of the side part 12 of the bathtub 10 can be enhanced.
