Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ceiling of a bathroom such as a system bathroom, and more particularly to a bathroom ceiling for preventing dew condensation generated on a dome-shaped ceiling panel from directly falling into the bathroom.

[0002]

2. Description of the Related Art Conventionally, as a bathroom ceiling of this type, for example, Japanese Patent Application Laid-Open No.
No. 1 discloses this. The former (JP-A-7-2170)
No. 50), the bathroom ceiling disclosed in FIG.
As the ceiling member 50 disposed at a predetermined angle,
Adhering to the lower surface of the ceiling member 50 by using an uneven groove-shaped plate 51 having a concave portion 51a and a convex portion 51b shown in (a) and a saw blade-shaped plate 52 having a valley portion 52a and a mountain portion 52b shown in (b). The condensed condensation is transferred to the concave portion 51a, the convex portion 51b, or the valley portion 52a.
Flow along the ridges 52b, that is, dew condensation
By collecting and flowing in the valley 52a, it is possible to prevent dew condensation from directly falling into a bathtub or a washing place.

As shown in FIG. 8, a bathroom ceiling disclosed in the latter (Japanese Patent Application Laid-Open No. 2-85451) has an arc-shaped, rippled, saw-toothed surface on the surface of a ceiling member 61 arranged in an inclined state. Forming a concave portion 61a or a convex portion 61b having a triangular wave shape or the like, preventing the dew condensation from diffusing to the other surface by the convex portion 61b, and collecting the dew condensation in the vicinity by the concave portion 61b and flowing the same toward the wall panel. It is configured to flow down from the wall panel.

[0004]

However, in these bathroom ceilings, uneven surfaces 51a, 51b, 61a, and 61a are provided on the surfaces of ceiling members 50 and 61 provided in an inclined state.
61b and valleys 52a and 52b are formed.
a, 61a and the valley 52a, the collected dew is caused to flow. Therefore, when the inclination angle of the ceiling members 50, 61 is large, the collected dew is formed by the recesses 51a, 61a.
It flows down well along a and the like, thereby preventing the condensation from directly dropping into a bathtub or a washing place. However, the ceiling members 50, 61
When the inclination angle is small, dew condensation may occur in the concave portions 51a, 61a.
In some cases, the condensation does not flow down well along a and the like, and in such a case, the dew grows along with the gentle flow down along the recesses 51a and 61a to form a large dew. There was a problem that it was easy to drop directly into a bathtub or a washing place.

[0005] In particular, in a system bathroom, a dome-shaped ceiling panel is used in order to obtain a sense of openness by, for example, improving the design and raising the ceiling surface. In such a case, it is difficult to set a small round shape due to restrictions on the installation height of the bathroom in the house, and a relatively large round shape (that is, a gentle inclination angle) is set. In general, among these ceiling panels, the inclination angle near the zenith is generally set to be more gradual. In the case of such a ceiling panel, the above-described ceiling members 50 and 6 are used.
It is difficult to reliably prevent dew condensation from dropping in the shape of 1.

In view of such circumstances, the present invention has conducted intensive studies on the relationship between the shape of the concave and convex portions provided on the dome-shaped ceiling panel and the growth and drop of dew condensation, and found that the size of the concave portion is set to a predetermined value. It has been found that even if the inclined surface of the ceiling panel is gentle, it is possible to reliably prevent the direct drop of dew condensation. An object of the present invention according to claim 1 of the present invention is to provide a bathroom ceiling capable of reliably preventing dew condensation from directly falling from a dome-shaped ceiling panel, and an object of claim 2 is as follows. Another object of the present invention is to provide a bathroom ceiling capable of more reliably preventing condensation from dropping. A third object of the present invention is to provide a bathroom ceiling capable of improving the cleanability of a ceiling panel, in addition to the object of the first or second invention.

[0007]

In order to achieve the above object, according to the present invention, there is provided a bathroom ceiling having a ceiling panel disposed above a wall panel.
The ceiling panel is formed in a dome shape, and a plurality of groove-shaped recesses are formed along the inclined direction of the inclined surface. Is set to a predetermined value that can be divided into adjacent concave portions. The invention according to claim 2 is characterized in that the predetermined value is 1 mm or more and 5 mm or less.

[0008] With this configuration, the dew condensation on the ceiling panel formed by the adhesion of moisture in the bathroom is caused by a plurality of groove-shaped concave portions provided along the inclination direction of the dome-shaped inclined surface. Grow while flowing down. At this time, the condensate that has grown is 5 mm when the interval between adjacent concave portions is 1 mm or more.
Since it is set to the following predetermined value, before the dew condensation becomes equal to or more than the holding capacity of the concave portion, it is divided into adjacent concave portions,
It flows further down along each recess. As a result, the dew flowing down each concave portion does not exceed the holding ability of the depressed portion, and the dew drops satisfactorily flow down to the wall panel, thereby reliably preventing the dew condensation from directly falling into a bathtub or a washing place.

Further, the invention according to claim 3 is characterized in that the depth of the recess is 0.1 mm or more and 0.5 mm or less, and the width is 1 mm or more and 3 mm or less.
mm or less. With this configuration, the depth and width are set to values that are easy to clean in each of the recesses whose intervals are set so that dew condensation does not drop beyond the holding capacity, so that the ceiling panel Cleanability is improved.

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 to 5 show an embodiment in which a bathroom ceiling according to the present invention is applied to a system bathroom, FIG. 1 is a schematic perspective view of the inside, FIG. 2 is a plan view of a main part of a ceiling panel, FIG. 3 is a cross-sectional view taken along the line AA of FIG. 2, and FIGS. 4 and 5 are schematic diagrams showing a flowing down state of dew condensation.

In FIG. 1, a bathroom 1 includes a waterproof pan 2,
Four wall panels 3a to 3d (wall panel 3d is not shown)
And the ceiling panel 4 and the like. A bathtub 5 is arranged on the wall panel 3a side of the waterproof pan 2, and a washing place 6 is provided on the waterproof pan 2 and a counter 8 is arranged on the wall panel 3b side of the washing pan 6 on which a mirror 7 and the like are attached. Have been. Further, a mirror panel 11 in which the mirror 7, the storage shelf 9, the lighting device 10, and the like are integrated is disposed on the wall panel 3b.

The ceiling panel 4 is formed of, for example, a ceiling member 4a arranged above the bathtub 5 and a ceiling member 4b arranged above the washing place 6. The two ceiling members 4a, 4b
Are each formed in a dome shape, and a substantially arc-shaped inclined surface is formed on the surface thereof. Further, the ceiling material 4a and the ceiling material 4b are provided with a stepped portion 13 at a connection portion between the ceiling materials 4a and 4b, for example, by disposing the ceiling material 4a at a high position and the ceiling material 4b at a low position. ing. Note that the ceiling member 4 is not limited to the connection structure of the two ceiling members 4 a and 4 b having the step portion 13, and it is of course possible to use one dome-shaped ceiling member.

The ceiling material 4a of the ceiling panel 4
4b, a plurality of linear concave portions 14 are formed over substantially the entire area of the respective inclined surfaces in the direction of inclination a.
Has a shape set as follows, as shown in FIGS. 2 and 3. That is, the distance between the adjacent concave portions 14 is L = 1 mm to 5 mm (preferably L = 2 mm to 3 m
m), the depth of the concave portion 14 is H = 0.1 mm to 0.5 mm
And the width of the concave portion 14 is set to W = 1 mm to 3 mm.

Here, the test results concerning the recessed portion 14 of the ceiling panel 4 and the dew condensation state will be described. First, as a sample, a space L = 2 mm and a depth H = 0.2 m were formed on the surface of a 30 cm × 80 cm × 5 mm sample plate made of PS resin.
m, a sample 1 having a concave portion 14 having a width W = 1 mm, a sample 2 having a concave portion 14 having an interval L = 4 mm, a depth H = 0.2 mm, and a width W = 1 mm, and an interval L = 6 mm, a depth H =
Sample 3 having a recess 14 having a width of 0.2 mm and a width W of 1 mm
It was created. Then, these samples 1 to 3 were tilted at an angle of 3 /
10, the internal temperature was 40 ° C., the external temperature was 0 ° C., and the humidity was maintained at 95% or more, and the amount of dew condensation falling during 1 hour and 30 minutes was measured.

As a result, the amount of dew drop of the sample 1 and the sample 2 is relatively small, 4.8 g and 12.2 g, and most of the dew is divided before dropping. Flowed down to the side. On the other hand, the amount of drop of sample 3 was 58.5 g, which was large, and dew fell down from the middle of the sample plate.

The differences between the results of Samples 1 and 2 and Sample 3 are considered as follows. That is, samples 1 and 2
In the case of, as shown in FIG. 4, by setting the interval L between the concave portions 14 to a predetermined value, the dew condensation K0 that grows while flowing down the concave portions 14 grows to a predetermined size and becomes the dew condensation K1. Recesses 14 on both sides adjacent to the outer peripheral edge of condensation K1
, Each of which receives an inward suction force (tensile force due to surface tension) of the concave portions 14 on both sides and is divided into three dew condensations K2 to K4. Flows down in each recess 14.

That is, the dew condensation K1 is divided before the dew holding capacity of each depressed portion 14 reaches the limit of the dew condensation holding capability by the depressed portions 14 having the interval L set to a predetermined value. In this case, the amount of dew drops is reduced, and in the case of the actual ceiling panel 4, the drop of dew is reliably prevented. On the other hand, in the case of the sample 3, as shown in FIG. Grew up,
The dew condensation K5 directly falls, and the amount thereof is greatly increased. When the interval L between the concave portions 14 is less than 1 mm, it has been confirmed that the interval L is too small and the grown dew does not split.

As described above, in the ceiling panel 4 of the above embodiment, the dome-shaped ceiling members 4a, 4b
A plurality of linear recesses 14 on the inclined surface
And the distance L between the adjacent concave portions 14 is 1 mm.
Since it is set to 5 mm (preferably 2 mm to 3 mm), when the dew flowing down along the recess 14 grows to a predetermined size corresponding to the interval L, the dew is divided and the inside of each recess 14 is divided. The water can flow down and flow downward from the wall panels 3b and 3d, so that dew condensation that directly falls from the ceiling panel 4 to the bathtub 5 or the washing place 6 can be reliably prevented.

In particular, since the concave portion 14 is formed over the entire sloped surface of the ceiling members 4a and 4b, even in the gently inclined zenith portion of the dome-shaped ceiling panel 4, the concave portion 14 prevents the dew condensation from falling. While preventing both sides (wall panel 3b,
3d side), and it is possible to reliably prevent the dew condensation from dropping on the dome-shaped ceiling panel 4.

Further, the depth of the concave portion 14 is H = 0.1 mm or more.
0.5 mm, the width of the concave portion 14 is set to W
= 1 mm to 3 mm, which is a value that facilitates cleaning, it is possible to prevent the accumulation of dirt on the bottom surface of the concave portion 14 and the corners thereof, and to form the concave portion 14 itself when cleaning the ceiling panel 4. Can be easily cleaned by washing with water or the like, and a clean ceiling panel 4 can be obtained over a long period of time.

Further, by setting the respective dimensions of the concave portion 14, the design of the ceiling panel 4 itself of the bathroom 1 is not lost, and the concave portion 14 can give a design change to the ceiling panel 4. The design value can be improved, and the recess 14 can be easily formed on the ceiling panel 4 by molding or the like, so that an inexpensive ceiling panel 4 can be obtained.

In the above embodiment, the end of the recess 14 of the ceiling panel 4 is a vertical surface. However, the present invention is not limited to this. For example, as shown in FIG. 14a may be formed in a round shape, and in this case, the round shape may be a convex round shape or a concave round shape indicated by a two-dot chain line. Further, the cross-sectional shape of the concave portion 14 may be formed, for example, so that the end portion 14a may have an inclined surface, the concave portion 14 may be formed in a semicircular arc shape,
Can be variously changed without departing from the gist of each invention according to the present invention, for example, by forming a wave shape instead of a straight line.
