Description
Technical Field
The present disclosure relates to a toilet seat having a water repellent function of preventing adhesion of water droplets, and a toilet seat device provided with the toilet seat.
Background
Conventionally, such a toilet seat has the following structure: by forming a fine columnar protrusion on the entire surface of the back surface of the toilet seat, the contact angle between the tip end portion of the protrusion and water increases, thereby forming a water-repellent function (for example, refer to patent document 1).
Fig. 9A is a plan view of the back surface of the conventional toilet seat described in patent document 1, and fig. 9B is a cross-sectional view of a projection provided in the conventional toilet seat described in patent document 1. As shown in fig. 9A, the rear surface 2 of the toilet seat 1 is integrally formed with a front flat surface portion 3 of the toilet seat 1 and a rear inclined portion 4 of the toilet seat 1, and a protrusion 5 as shown in fig. 9B is formed over substantially the entire surfaces of the flat surface portion 3 and the inclined portion 4.
As shown in fig. 9B, the protrusion 5 has a substantially cylindrical shape, and a tip end portion is formed in a substantially hemispherical shape. The protrusion 5 has a shape with a height a of about 5 μm and a width direction length B of about 5 μm. The distance P between the central axes of the projections 5 is set to about 10 μm.
However, in the above-described conventional structure, when the flat surface portion 3 and the inclined portion 4 are integrally molded, for example, as shown in fig. 9B, when the tip portions of the protrusions 5 of the flat surface portion 3 are arranged at the same height, the tip portions of the protrusions 5 of the inclined portion 4 are arranged with steps instead of being arranged at the same height in consideration of the mold releasing direction at the time of molding. In such a case, the contact angle between the tip of the protrusion 5 and water cannot be maintained at an appropriate angle, and there is a problem in that the water repellent function is lowered.

As shown in fig. 4 and 6, the toilet 300 is configured by using, as main structural members, an upper toilet case 310 integrally molded from a resin material mainly composed of polypropylene, a toilet heater 330 provided with heating wires (not shown) in a soaking plate made of aluminum foil, and a lower toilet case 320 integrally molded from a resin material mainly composed of polypropylene, from the upper surface side. In its completed state, the upper toilet seat case 310 and the lower toilet seat case 320 are engaged with each other at their inner and outer peripheral edges to form an annular shape with a hollow interior.
As shown in fig. 4, the upper toilet seat case 310 is integrally molded by injection molding using a resin material mainly made of polypropylene. The upper toilet seat case 310 includes a seating portion 311 formed in a substantially elliptical ring-like shape constituting the main body 301, and an upper support portion 312 protruding obliquely upward from a rear end portion of the seating portion 311 constituting the support portion 302.
As shown in fig. 6, the upper toilet seat case 310 is formed such that the cross section of the seating portion 311 has a substantially mountain shape. The upper surface of the seating portion 311 is formed into a gently curved surface suitable for seating. The inner and outer circumferences of the seating portion 311 are curved downward, and the tip end portion thereof is formed with substantially perpendicular inner and outer circumferences.
As shown in fig. 4, the lower toilet seat case 320 is integrally molded by injection molding using a resin material mainly made of polypropylene. The lower toilet seat case 320 is formed in a substantially elliptical ring shape having substantially the same shape as the seating portion 311 of the upper toilet seat case 310. The lower toilet seat case 320 includes a lower body portion 321 and a lower support portion 322. The lower support portion 322 has substantially the same shape as the upper support portion 312 of the upper toilet seat case 310, and is formed to protrude obliquely upward from the rear end portion of the lower body portion 321.
The lower toilet seat case 320 has an inner periphery and an outer periphery bent upward, and an inner periphery and a lower outer periphery formed at a distal end portion thereof.
The inner and outer circumferences of the upper and lower toilet housings 310 and 320 have substantially the same shape, respectively.

Structure of & lt 3 & gtwater repellent treatment part
As shown in fig. 5, the lower surface of the lower toilet seat case 320 is continuously and integrally formed with a horizontal portion 323 corresponding to the lower body portion 321 and an inclined portion 324 corresponding to the lower support portion 322. The switching portion 325 of the horizontal portion 323 and the inclined portion 324 is connected by a curved surface disposed substantially linearly behind the lower toilet seat case 320.
The water repellent treatment 340 is formed on substantially the entire surfaces of the horizontal portion 323 and the inclined portion 324. Further, a flat outer peripheral edge 351 and an inner peripheral edge 352 (see fig. 5) formed in a band shape along the outer periphery and the inner periphery are formed on the outer periphery and the inner periphery of the water-repellent treatment portion 340, respectively.
In the water repellent treatment 340, fine irregularities of micrometer scale are formed continuously in a substantially straight line so as to form a ridge line from substantially the front end of the horizontal portion 323 to substantially the rear end of the inclined portion 324. More specifically, in the water-repellent treatment portion 340, a convex shape and a groove shape are formed so that ridge lines are formed in a direction orthogonal to the switching portion 325.
With such a configuration, when the same concave-convex shape is formed in the horizontal portion 323 and the inclined portion 324 having different angles by injection molding, the mold release direction at the time of molding can be uniformed, and therefore, the manufacturing of the mold and the molding operation can be simplified.
Fig. 7 is a schematic diagram showing details of the portion D shown in fig. 6.
As shown in fig. 7, the cross-sectional shape of the convex portion 341 of the water-repellent treatment portion 340 is substantially triangular, and the bottom of the concave portion 342 of the water-repellent treatment portion 340 is formed to be substantially planar. The convex portions 341 and the concave portions 342 are alternately formed at equal intervals.
In the present embodiment, the convex portion 341 is formed in a triangular shape having a height H of approximately 23 μm and a length L of the base of approximately 18 μm. The tip of the convex portion 341 is formed to have a radius R of 1 μm or less. In the case of the triangular shape of the above-described size, the tip end portion of the convex portion 341 is formed at approximately 45 degrees. The angle of the distal end portion of the convex portion 341 is preferably from about 45 degrees to about 70 degrees. In addition, the height H of the convex portion 341 is preferably 10 μm or more in terms of water repellency, and the height H of the convex portion 341 is preferably 50 μm or less in terms of strength or the like.
The width M of the bottom edge of the recess 342 of the water-repellent treatment 340 is formed to be approximately 15 μm. The uneven shapes of the water repellent treatment 340 are set such that the pitch N between the tip portions of the adjacent convex portions 341 is approximately 33 μm. The uneven shape is formed over the entire surface of the water-repellent treatment 340. The pitch N of the concave-convex shape is preferably 2 μm or more and 50 μm or less.
As shown in fig. 6, the tip end of the convex portion 341 is disposed at a position not protruding from the surfaces of the outer peripheral edge 351 and the inner peripheral edge 352 adjacent to the water-repellent treatment portion 340. With such a structure, the effect of suppressing deformation or breakage of the convex portion 341 in use of the toilet seat 300 can be obtained.
Effect of water repellent treatment part of < 4 ]
Fig. 8A is a schematic diagram illustrating the contact angle of the surface of the substrate with the outer surface of the water droplet. Fig. 8B is a schematic diagram illustrating the roll-off angle of water droplets on a substrate.
When water is applied to the water-repellent treatment portion 340 having the above-described structure by scattering of urine, cleaning water, or the like, the water becomes water droplets on the surface of the water-repellent treatment portion 340 and adheres thereto. By tilting the toilet seat 300 provided with the water-repellent treatment portion 340, the attached water drops fall from the surface of the water-repellent treatment portion 340 according to the tilt angle.
For example, when urine or cleaning water is applied to the water-repellent treatment unit 340 in a state where the toilet seat 300 is raised, the urine or cleaning water is formed into small water droplets and slides down along the irregularities of the water-repellent treatment unit 340 to fall into the toilet bowl 110.
In general, as an index for evaluating the water repellency, evaluation was made based on a contact angle E as shown in fig. 8A and a roll-off angle F as shown in fig. 8B. That is, it is evaluated that the larger the contact angle E, the smaller the roll-off angle F, and the higher the water repellency.
As shown in fig. 8A, the contact angle E is an angle formed by the contact surface of the substrate 360 and the outer surface of the water droplet in a state where the water droplet is attached to the surface of the substrate 360. The closer the contact angle is to 0 degrees, the easier it is for the substrate 360 and the water droplet to adhere, and the closer the contact angle is to 180 degrees, the more difficult it is for the water droplet to adhere to the substrate 360.
As shown in fig. 8B, the roll-off angle F is an angle at which the substrate 360 to which the water droplets adhere gradually tilts from a horizontal position and the droplets start to slip. The closer the roll-off angle F is to 0 degrees, the easier it is for the water droplets to be removed from the substrate 360, and the closer the roll-off angle F is to 90 degrees, the more difficult it is for the water droplets to separate from the substrate 360.
In the case of a normally molded polypropylene material which has not been subjected to water repellency treatment, the contact angle E is about 90 degrees, and the roll angle F is 90 degrees or more.
In contrast, the water-repellent treatment unit 340 of the present embodiment can exhibit water-repellent performance in which the contact angle E is 150 degrees or more and the roll angle F is 30 degrees or less.
Further, the water repellent treatment 340 of the present embodiment is formed with fine ridge-like concave-convex shapes continuously in a substantially straight line from the substantially front end of the horizontal portion 323 to the substantially rear end of the inclined portion 324. With such a configuration, the demolding direction of the mold at the time of molding can be unified. Thus, the manufacturing and molding operations of the mold can be simplified, and the toilet seat 300 having excellent water repellency can be provided at low cost.
In particular, by forming the convex portion 341 so that the cross-sectional shape of the convex portion becomes substantially triangular, the water repellency can be further improved. In addition, with such a structure, the manufacturing cost of the mold can be reduced. Further, with such a configuration, the operation of taking out the molded article at the time of molding is facilitated, and deformation of the molded article can be suppressed.
The water repellent treatment 340 of the present embodiment is configured to have a continuous ridge shape. With such a configuration, when the water repellent treatment portion 340 is attached with the attached matter or dirt, cleaning by wiping is easy. Further, with such a structure, the effect of suppressing the wear and deformation of the convex portion 341 can be obtained, and durability can be improved.
In the present embodiment, the tip end portions of the convex portions 341 of the water-repellent treatment portion 340 are configured not to protrude from the surfaces of the outer peripheral edge 351 and the inner peripheral edge 352 adjacent to the water-repellent treatment portion 340. With such a structure, the effect of suppressing deformation or breakage of the convex portion 341 of the water-repellent treatment portion 340 during use of the toilet seat 300 can be obtained.
In the present embodiment, the cross-sectional shape of the protruding portion 341 is a simple triangle, but the present invention is not limited to this, and for example, the portion of the tip end portion on the opposite side to the tip end portion may be formed in two stages, that is, a portion having an acute angle and an obtuse angle. By adopting such a shape for the convex portion 341, the strength of the convex portion 341 can be increased.
In the present embodiment, the cross-sectional shape of the protruding portion 341 is a substantially triangular shape, but the present invention is not limited to this, and may be a substantially circular arc shape, a substantially trapezoidal shape, or a combination of these shapes.
In the present embodiment, polypropylene as a material used for the toilet seat 300 is used as a main material, but the present invention is not limited thereto, and other resin materials such as ABS resin used for a general molded article may be used.
Industrial applicability
As described above, the present disclosure can be used for a toilet seat and a toilet seat device which have high durability and can perform water repellency treatment at low cost, and can also be used for other applications such as water use equipment using molded articles of resin materials.
