[0029] The toilet seat device 20 has a matte appearance with low
glossiness. The glossiness of an outer surface 20A of the toilet
seat device 20 is equal to or less than the glossiness of an outer
surface 11A of the toilet body 11. In the present disclosure,
glossiness of the outer surface 20A of the toilet seat device 20
means glossiness of a surface that is easily seen from an upper
side, a front side, a right side, and a left side when the toilet
lid 50 is closed. The glossiness of the outer surface 20A of the
toilet seat device 20 is also referred to as first glossiness. The
glossiness of the outer surface 11A of the toilet body 11 means
glossiness of a surface that is not covered with the closed toilet
lid 50 and is easily seen from a front side, a right side, and a
left side. The glossiness of the outer surface 11A of the toilet
body 11 is also referred to as second glossiness. The outer surface
20A of the toilet seat device 20 includes an outer surface of the
toilet seat box 30 and an outer surface of the toilet lid 50. The
outer surface of the toilet seat box 30 is a top surface, a front
surface, a rear surface, a left surface, and a right surface of the
upper cover 34, and a surface of the lower cover 33 that is not
covered with the upper cover 34 among a front surface, a rear
surface, a left surface, and a right surface of the lower cover 33.
The outer surface of the toilet lid 50 is a top surface and an
outer peripheral surface of the toilet lid 50 in a state where the
toilet lid 50 is closed. Hereinafter, the surface located opposite
the outer surface of the toilet lid 50 is referred to as the
under-side surface 50A of the toilet lid 50. The outer surface 11A
of the toilet body 11 is an outer peripheral surface of the
peripheral wall 14.
[0030] In the toilet seat device 20, glossiness of the outer
surface of the toilet seat 40 is also equal to or less than
glossiness of the outer surface 11A of the toilet body 11. The
outer surface of the toilet seat 40 is a top surface, an outer
peripheral surface, an inner peripheral surface, and a lower
surface of the toilet seat 40 in a state where the toilet seat 40
is closed. In the toilet 10, similarly to the outer surface 20A of
the toilet seat device 20, glossiness of the outer surface of the
side cover 15 is also equal to or less than glossiness of the outer
surface 11A of the toilet body 11.
[0031] In the present disclosure, a state in which the glossiness
is equal to or less includes a case where the glossiness of the
outer surface 20A is equal to the glossiness of the outer surface
11A and a case where the glossiness of the outer surface 20A is
lower than the glossiness of the outer surface 11A. The state in
which the glossiness is equal means that the difference between the
glossiness of the outer surface 20A and the glossiness of the outer
surface 11A is within .+-.10 and preferably within .+-.5 when
measured by a glossiness measurement method to be described later.
That is, in the present disclosure, the glossiness of the outer
surface 20A of the toilet seat device 20 is equal to or less than a
value obtained by adding 10 to the glossiness of the outer surface
11A of the toilet body 11 and preferably equal to or less than a
value obtained by adding 5 to the glossiness of the outer surface
11A of the toilet body 11 when measured by a method of measuring
glossiness to be described later.
[0032] The glossiness is measured as 60.degree. specular glossiness
by a gloss meter according to JIS-Z8741. As a gloss meter, for
example, the gloss meter (GM-268A, manufactured by KONICA MINOLTA,
INC.) can be used. The glossiness of the outer surface 20A of the
toilet seat device 20 is measured at one location of each of a flat
region on the outer surface of the toilet seat box 30 and a flat
region on the outer surface of the toilet lid 50. The glossiness of
the outer surface 11A of the toilet body 11 is measured at one
location of a flat region on the outer peripheral surface of the
peripheral wall 14. When both the glossiness of the outer surface
of the toilet seat box 30 and the glossiness of the outer surface
of the toilet lid 50 are equal to or less than the glossiness of
the outer peripheral surface of peripheral wall 14, it is
determined that the glossiness of the outer surface 20A of the
toilet seat device 20 is equal to or less than the glossiness of
the outer surface 11A of the toilet body 11.
[0033] The glossiness of the outer surface 20A of the toilet seat
device 20 and the glossiness of the outer surface 11A of the toilet
body 11 are 50 or less. The glossiness of the outer surface 11A of
the toilet body 11 is preferably 10 or more and 50 or less, more
preferably 15 or more and 45 or less, and still more preferably 20
or more and 40 or less. When the glossiness of the outer surface
11A of the toilet body 11 is within the above range, it is easy to
manufacture the toilet body 11 with low gloss. The glossiness of
the outer surface 20A of the toilet seat device 20 is preferably 5
or more and 40 or less, more preferably 8 or more and 35 or less,
and still more preferably 10 or more and 30 or less. When the
glossiness of the outer surface 20A of the toilet seat device 20 is
within the above range, it is easy to adjust the glossiness
according to the glossiness of the toilet body 11.
[0034] The glossiness of the outer surface 20A of the toilet seat
device 20 is preferably less than the glossiness of the outer
surface 11A of the toilet body 11. According to this configuration,
even when illumination light and natural light strikes from above
in the installed state of the toilet 10, the luster of the toilet
seat device 20 with respect to the toilet body 11 is suppressed,
and the appearance of the toilet 10 as a whole can be
harmonized.
[0035] As illustrated in FIGS. 4 to 7, the toilet seat device 20
has a coated surface and a non-coated surface. In FIGS. 4 and 5,
the coated surface is shaded, and the non-coated surface is drawn
in a white outlined shape. In FIGS. 7 and 8, the coating film 29 is
schematically drawn by a thick solid line.
[0036] The outer surface 20A of the toilet seat device 20 is a
coated surface. That is, the outer surface 20A of the toilet seat
device 20 is a surface on which the coating film 29 is formed by
applying coating material to a base material 28. In the present
disclosure, the outer surface 20A being a coated surface means that
a surface, of the outer surface 20A, that is easily seen from an
upper side, a front side, a right side, and a left side is a coated
surface. That is, it can be said that the outer surface 20A is a
coated surface as long as at least the easily visible surface of
the outer surface 20A is a coated surface, and the surface that is
not easily visible may not be coated. The base material 28 is made
of a synthetic resin and is colored in the same color as the
coating film 29. In the coating film 29, a transparent coating
layer is laminated on a color layer in white or the like. In the
non-coated surface, the base material 28 is exposed. The glossiness
of the coating film 29 is lower than the glossiness of the base
material 28. That is, the outer surface 20A of the toilet seat
device 20 is adjusted to have glossiness equal to or less than
glossiness of the outer surface 11A of the ceramic toilet body 11
by forming the coating film 29 on the base material 28. The outer
surface of the toilet seat 40 is also a coated surface in which the
coating film 29 is formed by applying coating material to the base
material 28. The outer surface of the side cover 15 is also a
coated surface similar to the outer surface 20A of the toilet seat
device 20.
[0037] As illustrated in FIGS. 4 and 6, the sliding surfaces 31A
and 31B on which the toilet seat shaft portion 46 slides and the
sliding surface 31C on which the toilet lid shaft portion 55 slides
are non-coated surfaces. That is, on the left surface of the toilet
seat box 30, the coating film 29 is not formed on the opening edge
and the inner peripheral surface of the toilet seat support portion
24 and the outer surface of the toilet lid support portion 27.
Around the sliding surface 31B, the non-coated surface is provided
in a range wider than a range in which the flange portion 47 of the
toilet seat shaft portion 46 slides. The non-coated surface
provided on the sliding surface 31A and on and around the sliding
surfaces 31B are hidden by the toilet seat 40, and are provided in
a range that is hardly visually recognized by the user when viewed
from the side. The non-coated surface provided on the sliding
surface 31C is hidden by the toilet lid 50 and is provided in a
range that is hardly visually recognized by the user when viewed
from the side. In the toilet seat box 30 illustrated in FIG. 3, the
inner peripheral surfaces 36A and 37A with which the toilet seat
driving unit 23 and the toilet lid driving unit 26 are in contact
are non-coated surfaces. As illustrated in FIG. 7, in the toilet
seat 40, the contact surface 42A, of the rear leg portion 42, which
comes into contact with the toilet body 11 is a non-coated surface.
As illustrated in FIGS. 6 and 7, the under-side surface 50A of the
toilet lid 50 is a non-coated surface. In the toilet seat box 30,
the under-side surface of upper cover 34 and the under-side surface
of lower cover 33 are non-coated surfaces.
[0038] Functions and effects of the embodiments configured as
described above will be described.
[0039] The toilet seat device 20 of some embodiments is disposed on
an upper part of the toilet body 11. The glossiness of an outer
surface 20A of the toilet seat device 20 is equal to or less than
the glossiness of an outer surface 11A of the toilet body 11. Since
the toilet seat device is disposed on the upper part of the toilet
body 11, the toilet seat device is more likely to receive
illumination light and natural light than the toilet body 11, and
the gloss is easily felt by the user. When the glossiness of the
outer surface of the toilet seat device is remarkably higher than
the glossiness of the outer surface 11A of the toilet body 11,
there is a concern that the sense of unity of the toilet may be
impaired due to the strong luster of the toilet seat device. In the
toilet seat device 20, since the glossiness of the outer surface
20A of the toilet seat device 20 is equal to or less than the
glossiness of the outer surface 11A of the toilet body 11, the
luster of the toilet seat device 20 is suppressed, and toilet 10
exhibits a unified appearance. Therefore, according to the toilet
seat device 20, the appearance of the toilet 10 as a whole can be
harmonized.
[0040] In some embodiments, the glossiness of the outer surface 20A
and the glossiness of the outer surface of the toilet body 11 are
50 or less. According to this configuration, the appearance in
which the luster of the toilet 10 is suppressed as a whole can be
obtained.
[0041] In some embodiments, the outer surface 20A is a coated
surface. According to this configuration, the glossiness of the
outer surface 20A can be easily adjusted by coating. For this
reason, for example, the glossiness of the outer surface 20A can be
appropriately set in accordance with the toilet body 11 made of
ceramics different in material from the toilet seat device 20.
[0042] The toilet seat device 20 of some embodiments includes the
toilet seat shaft portion 46 and the toilet lid shaft portion 55
which are movably provided. The sliding surfaces 31A, 31B, and 31C
on which the toilet seat shaft portion 46 and the toilet lid shaft
portion 55 slide are non-coated surfaces. According to this
configuration, there is no concern that the coating films on the
sliding surfaces 31A, 31B, and 31C are peeled off by sliding of the
toilet seat shaft portion 46 and the toilet lid shaft portion 55.
For this reason, the design of the toilet 10 is hardly impaired due
to peeling and peeling residue of the coating film. Furthermore, it
is possible to suppress deterioration of the dimensional accuracy
of the sliding surfaces 31A, 31B, and 31C due to the film thickness
of the coating film, which may impair the slidability of the toilet
seat shaft portion 46 and the toilet lid shaft portion 55.
[0043] The toilet seat device 20 of some embodiments includes a
toilet seat having the rear leg portions 42. The contact surface
42A, of the rear leg portion 42, which comes into contact with the
toilet body 11 is a non-coated surface. According to this
configuration, there is no concern that the coating film on the
contact surface 42A is peeled off due to contact of the contact
surface 42A with the toilet body 11 or application of the weight of
the seated person to the contact surface 42A when the seated person
sits on the toilet seat 40. For this reason, the design of the
toilet 10 is hardly impaired due to peeling and peeling residue of
the coating film.
[0044] The toilet seat device 20 of some embodiments includes the
toilet lid 50 rotatably attached to the toilet seat box 30. The
under-side surface 50A of the toilet lid 50 is a non-coated
surface. According to this configuration, the area of the coated
surface can be reduced to contribute to cost reduction as compared
with the configuration in which the under-side surface 50A of the
toilet lid 50 is coated. In the configuration in which the
upper-side surface of the toilet lid 50 is a coated surface and the
under-side surface 50A is a non-coated surface, the boundary
between the coated surface and the non-coated surface can be
disposed near the end surface of the toilet lid 50. For this
reason, the boundary between the coated surface and the non-coated
surface is hardly visually recognized by the user, and the design
property of the toilet lid 50 is hardly impaired due to formation
of the coating film 29. In the configuration in which the
upper-side surface of the toilet lid 50 is a coated surface and the
under-side surface 50A is a non-coated surface, coating can be
easily performed separating the coated surface from the non-coated
surface.
[0045] The present disclosure is not limited to the embodiments
described with reference to the above description and drawings, and
for example, the following embodiments are also included in the
technical scope of the present disclosure.
[0046] The outer surface of the toilet seat device need only
include a surface that can be easily seen from an upper side, a
front side, a right side, and a left side when the toilet lid is
closed. The glossiness of the top surface of the lower cover of the
toilet seat box and the outer surface of the toilet seat is not
particularly limited. However, at least one of the glossiness of
the top surface of the lower cover of the toilet seat box and the
glossiness of the outer surface of the toilet seat is preferably
equal to the glossiness of the outer surface of the toilet seat box
and the outer surface of the toilet lid.
[0047] The values of the glossiness of the outer surface of the
toilet seat device and the glossiness of the outer surface of the
toilet body are not limited. For example, when the glossiness of
the outer surface of the toilet body is larger than 50, a
configuration in which the glossiness of the outer surface of the
toilet seat device is larger than 50 can also be included in the
technical scope of the present disclosure.
[0048] The outer surface of the toilet seat device is not limited
to the coated surface. For example, the glossiness of the outer
surface may be adjusted by fine embossing or the like. However,
from the viewpoint of antifouling property and the like, the outer
surface of the toilet seat device is preferably a smooth
surface.
[0049] The material of the base material of the toilet seat device
is not particularly limited. Depending on the material of the base
material, the coating film may have a primer layer that improves
the surface state and enhances adhesion with other layers.
[0050] The sliding surface is not limited to the sliding surface on
which the toilet seat shaft portion and the toilet lid shaft
portion slide. The sliding surface may be any of these sliding
surfaces, or may be another surface on which another movable member
slides.
[0051] The toilet seat device may not have a non-coated surface.
Even in the case of having a non-coated surface, the portion, the
position, and the range where the non-coated surface is formed can
be appropriately changed. For example, the under-side surface of
the toilet lid may be a coated surface. The top surface of the
lower cover may be a non-coated surface. The entire under-side
surface of the toilet seat may be a non-coated surface.
[0052] The toilet seat device may be configured not to include a
toilet lid, and include a toilet seat box and a toilet seat. In the
toilet seat device not including the toilet lid, the outer surface
of the toilet seat device may include the outer surface of the
toilet seat. In the toilet seat device, the remote controller
accommodated in the recess of the lower cover may also have
glossiness of 50 or less and a matte tone. When a cushion body (not
illustrated) is disposed on the top surface of the toilet seat, the
cushion body may also have glossiness of 50 or less and a matte
tone.
[0053] The toilet may not have the side cover, and substantially
the entire circumference of the toilet body may be made of
ceramics. Further, a side cover made of ceramics having glossiness
equal to that of the toilet body may be attached to the toilet
body.
