  However, in the above-described conventional configuration, when the user sits on the toilet seat, the toilet seat sticks to the skin, and the wet touch has a moist feeling. The toilet seat sticks to the skin and is not comfortable. Furthermore, even if the surface shape is devised, the antifouling property is not provided at the same time, and the uneven shape makes it easy to get dirt and makes the careability worse.

  In view of the above-mentioned conventional problems, the problem to be solved by the present invention is a dry touch that feels smooth when seated on a toilet seat, and a toilet seat surface treatment that has almost the same care as a conventional toilet seat To provide a toilet seat formed by the method and its processing method.

  In order to solve the above problems, the toilet seat surface treatment method of the present invention forms irregularities by increasing the roughness of the surface of the toilet seat, and the surface of the irregularities is made of a material having antifouling properties. As a result, the toilet seat surface has an antifouling property and has a dry and dry touch toilet seat surface that is less sticky to the skin when sitting.

  The toilet seat surface treatment method of the present invention makes it possible to feel the smooth feel when sitting on the toilet seat, and when cleaning it, it is easily soiled by wiping with water or detergent-containing water in the same manner as conventional toilet seats. Can be wiped off.

  The first invention is a toilet seat surface treatment method in which unevenness is formed by increasing the roughness of the surface of the toilet seat, and the surface of the unevenness is made of a material having antifouling properties. Since it has antifouling properties, it is easy to care for.

  The second aspect of the invention is a toilet seat surface treatment method in which the surface of the toilet seat in the first aspect of the invention is coated with a silicone-based paint, and then the surface of the toilet seat is roughened. The coating is simple and can be constructed at low cost.

  A third invention is a toilet seat surface treatment method in which the surface of the toilet seat according to the first invention is formed with a silicone-based paint that becomes porous after coating, and it is not necessary to roughen the surface. It is possible to form an uneven surface with antifouling properties.

  The fourth invention is a toilet seat surface treatment method in which the toilet seat surface in the first invention is coated with a paint added with inorganic particulate matter, and further coated with a material having antifouling properties. The level of the can be controlled arbitrarily, it is possible to achieve an optimal feel and a smooth surface can be realized. Furthermore, it is possible to easily remove dirt by coating the surface with a thin antifouling material.

  In the fifth invention, since the inorganic particulate matter added to the paint of the fourth invention is a porous body, the amount of inorganic particles added to the paint can be reduced, and the strength of the coating film is improved. It can be made to.

  The sixth invention is a toilet seat surface treatment method in which the average particle size of the inorganic particulate matter added to the paint is 20 μm or more on the surface of the toilet seat of the fourth or fifth invention. Is fully structured and can feel smooth when sitting on the toilet seat.

  The seventh invention is a toilet seat surface treatment method in which the surface of the toilet seat in the first invention is coated with a coating material added with a fibrous fibrous material, and further coated with a material having antifouling properties, and the strength of the coating film The toilet seat surface is smooth and comfortable and can be easily maintained because of its antifouling property.

  According to an eighth aspect of the invention, on the surface of the toilet seat of any one of the first to seventh aspects, the resin component itself contained in the coating material to be coated has a scratched pencil hardness of HB or more as a coating film after coating. Thus, the touch becomes close to dry touch.

  According to a ninth aspect of the invention, in the toilet seat surface of any one of the first to eighth aspects, the surface roughness of the irregularities formed on the toilet seat surface is 10-point average roughness (Rz) of 5 to 80 μm. When you sit on the toilet seat, you will feel a smoother feel.

  According to a tenth aspect of the present invention, in the surface of the toilet seat of any one of the fourth to ninth aspects, the unevenness formed by the film thickness of the antifouling material coated on the uneven surface being 5 μm or less. Since the portion is not completely covered with the antifouling material, it feels smooth when sitting on the toilet seat, and can be a surface treatment having antifouling properties.

  Since the eleventh invention is a toilet seat formed by the toilet seat surface treatment method according to any one of the first to tenth inventions, the toilet seat surface treatment according to any one of the first to tenth aspects described above. Has the effect of the method.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments. Further, in the description of the present embodiment, parts having the same configuration and the same operational effects are denoted by the same reference numerals, and redundant description will not be given.

(Embodiment 1)
FIG. 1 is a perspective view of a toilet seat subjected to surface treatment in the first embodiment of the present invention, and FIG. 2 is a cross-sectional view taken along the line AB of the toilet seat of FIG. Regarding the surface treatment of the toilet seat configured as described above, the treatment method and operation will be described below.

  According to FIG. 2, which is a cross-sectional view taken along the line AB of the toilet seat 1 in FIG. 1, the surface treatment layer 3 is provided on the surface of the toilet seat base 2 made of synthetic resin or stainless steel (the surface on which the user is seated), The surface of the surface treatment layer 3 is randomly formed in a number of irregularities 4. Further, an outermost surface layer is formed of a thin antifouling material 5 so as to cover the surface of the unevenness 4.

  When sitting on a toilet seat, the surface of the toilet seat so far is almost smooth, so the toilet seat surface and the buttocks are in close contact, or if you sit for a long time, the sweating from the buttocks will cause the space between the toilet seat to become sticky It is.

  However, in the toilet seat 1 according to the present embodiment, the unevenness 4 is formed on the toilet seat surface by roughening the surface roughness, so that the contact between the buttocks and the surface of the toilet seat 1 is reduced, and a smooth feeling is obtained. Sweat caused by perspiration is also released from the gaps formed by the irregularities 4, so that the feeling of stickiness can be eased. The surface treatment of the toilet seat 1 includes, for example, a silicone-based paint (including an organosiloxane type) rich in inorganic substances as a surface treatment material for the toilet seat 1. Then, after the surface of the toilet seat 1 is coated with a silicone-based paint, the surface is roughened by blasting, polishing or the like, and the unevenness 4 is applied to the surface.

  In this toilet seat surface treatment method, since a silicone-based paint is used as a coating material, the paint itself has a certain degree of antifouling property (water repellency), and its properties do not change even if the surface is appropriately processed into irregularities 4. . Therefore, the antifouling property of the surface is maintained, and even if it is soiled, it can be wiped off with water or water containing a detergent as easily as conventional.

  In particular, the effect of wiping and cleaning can be easily obtained by the antifouling property of the toilet seat surface as described above, and as a result, the surface of a large number of irregularities 4 can maintain its original function over a long period of time, resulting in a rough surface. The many irregularities 4 formed by roughening the degree can exhibit their original functions remarkably by having antifouling properties on the surface.

  Moreover, in this toilet seat surface treatment method, after coating a silicone-type paint on the surface, you may use what increased the quantity of the inorganic substance contained in the said silicone-type paint so that the coating film may become porous. By doing in this way, the unevenness | corrugation 4 is naturally formed in the surface of the toilet seat 1 after coating, and the post-processing which roughens the surface roughness is not required. The same effect can be obtained with inorganic paints other than silicone paints. For example, boron-based paint, water glass, and Tyranno paint are conceivable.

(Embodiment 2)
FIG. 3 is a cross-sectional view of a toilet seat subjected to surface treatment according to the second embodiment of the present invention. Regarding the surface treatment of the toilet seat configured as described above, the treatment method and operation will be described below.

  The toilet seat 1 is provided with a coating resin layer 6 containing an infinite number of inorganic particulate substances 7 on the surface of the toilet seat substrate 2 as the surface treatment layer 3 shown in FIG. Among the particulate substances 7, a large number of particulate substances 7 appear on the surface to form irregularities corresponding to the irregularities 4 shown in FIG. 2, and the antifouling material 5 is thinly coated on the surface of the paint resin layer 6. Surface treatment.

  As described above, by forming irregularities on the toilet seat surface, the contact between the buttocks and the toilet seat 1 can be reduced, and a smooth feeling can be obtained. Can be tempered.

  Further, as a surface treating agent for the toilet seat 1, an inorganic particulate material 7 (hereinafter referred to as inorganic particles) is added to the paint, and the inorganic particles form irregularities in the coated film after coating. The particulate matter 7 to be added is preferably a porous body, and the amount added can be reduced as compared with the case where the particulate matter 7 is not (if it is different depending on the porous material, the weight ratio is approximately 1/2 to 1 / 3) The coating strength is improved by that much.

  That is, in the case where the particulate material 7 of the paint resin layer 6 is not porous, the amount added is increased and the proportion of the inorganic particles per volume is increased, and the resin necessary for forming the coating film is small and fragile. . On the other hand, in the case of a porous material, the same effect is exhibited with a small addition amount, and since it is porous, the resin component of the paint enters the porous material and becomes entangled to increase the strength.

Further, the size of the inorganic particles to be added is preferably 20 μm or more, and if it is less than this, it is difficult to form irregularities on the surface of the toilet seat 1 and it is impossible to realize a smooth feeling. Desirably, the particle diameter is 120 m or less, and if it is more than this, it becomes a rough feeling and the strength of the coating film becomes weak. Table 1 below shows the feeling of smoothness on the toilet seat surface with respect to the particle size of the inorganic particles and the state of good or bad with x (bad), ○ (good), and Δ (intermediate).

Table 2 shows the roughness, smoothness and surface condition of the toilet seat surface with respect to the particle size of the inorganic particles as x (bad), ○ (good), and Δ (intermediate). When the ten-point average surface roughness (Rz) is in the range of 5 to 50 μm, the smooth feeling is the best.

Tables 1 and 2 were performed on 10 subjects, and the averages are shown in the table. A sample was prepared by coating a 40 cm square stainless steel plate with a paint blended at a predetermined ratio. The subjects sat on each sample for evaluation.

  FIG. 4 is a cross-sectional view of a toilet seat subjected to another surface treatment in the second embodiment of the present invention. In this toilet seat surface treatment method, the surface of the toilet seat substrate 2 is coated with a resin paint containing an inorganic fibrous substance 9, and then the paint resin layer 6 (partially containing an inorganic fibrous substance) is formed on the toilet seat surface. And a surface layer 10 containing a large amount of fibrous inorganic material 9. Further, the antifouling material 5 is thinly coated on the surface.

  As described above, since there are many fibrous substances on the toilet seat surface, a lot of irregularities corresponding to the irregularities 4 shown in FIG. 2 are randomly formed, the contact between the buttocks and the toilet seat is reduced, and a smooth feeling is obtained. Sweat generated by perspiration is also released from the gaps between the bumps, reducing the feeling of stickiness. Examples of the inorganic fibrous substance 9 include carbon (graphite) fiber, alumina fiber, whisker and the like.

  In addition, the resin to which the inorganic material is added is preferably a paint having a scratched pencil hardness of HB or more, and if it is less than this, a moist feeling (moist feeling) is produced. It will be reduced.

  As paints suitable for use, acrylic paints, silicone paints, paints containing polyester resins such as polyethylene terephthalate and polybutylene terephthalate, paints containing polyamide resins such as nylon, paints containing styrene resins such as polystyrene and ABS, Examples thereof include a paint containing a modified fluororesin modified with melamine or silicone.

  In addition, as a material having antifouling property, a fluorine compound containing a fluorocarbon group and a methoxy group, an ethoxy group, or a chlorosilyl group, a fluorine resin having a relatively small molecular weight, which can be dissolved in a fluorine-based solvent, and a functional group having a methyl group Examples include organosilanes, silicone resins or varnishes containing groups, or fluoroalkylsilanes.

  At this time, the film thickness of the antifouling material must be considerably smaller than the level of the unevenness. That is, even after the surface is coated with an antifouling material, it is necessary to leave an uneven shape. In view of the above ten-point average surface roughness and the like, it is desirable that the thickness be 5 μm or less. However, roughening with a material having a sufficiently high roughness level and a certain level of antifouling properties reduces the roughness and may result in a preferable surface state. In this case, what is necessary is just to change the film thickness of the material which has antifouling property according to a condition.

  The toilet seat formed according to each embodiment described above is provided on the toilet and is used, although not shown, only when it is detected that the user is seated or entering or exiting the toilet room, When applied to an instant heating toilet seat that instantaneously warms the toilet seat surface by energization and de-energization, the instant heating toilet seat momentarily increases in surface temperature, so that when the skin touches the toilet seat surface, the warmth is strongly increased. It feels softened as a result of smooth dry touch with less stickiness on the skin obtained due to the lack of contact surface with the skin due to the unevenness of the toilet seat surface, and a more preferable instantaneous heating type toilet seat can be obtained.

  In addition, the toilet seat formed according to each of the embodiments described above is provided on the toilet and is used, although not shown, only when it is detected that the user is seated or entering or exiting the toilet room, A so-called instantaneous heating type toilet seat that instantaneously warms the toilet seat surface by energization and de-energization, a cleaning nozzle that cleans the local part of the human body after the toilet, a drying device that dries the wet human body part after cleaning, and a deodorizing device are provided. It can also be applied to sanitary washing toilet seats.

And especially in sanitary washing toilet seats, even if the seating on the toilet seat becomes longer due to the use of a washing nozzle, drying device, etc., the skin feels sticky to the skin obtained due to the lack of contact surface with the skin due to the unevenness of the toilet seat surface etc. The feeling of softening is reduced as a result of the smooth dry touch, and the toilet seat can be more favorably sanitized.

  As described above, in the toilet seat surface treatment method of the present invention, the toilet seat substrate surface is provided with a layer having antifouling properties, and the surface is roughened to form irregularities on the toilet seat substrate surface. By coating the paint containing the substance to be formed and coating it with a thin antifouling material, the toilet seat surface has antifouling properties, and the dry touch of smoothness that has little stickiness to the skin when sitting The toilet seat surface can be realized, and it can also be applied to sanitary instruments and the like that come into direct contact with the skin.
