Abstract
The toilet seat includes a substantially horizontal main body portion and a support portion having a shape inclined obliquely upward from a rear portion of the main body portion in a horizontal state. The substantially flat horizontal surface of the lower surface of the main body is formed continuously with the inclined surface of the lower surface of the support portion. The toilet seat further includes a water-repellent treatment section in which a convex portion (341) and a concave portion (342) are continuously formed so as to form a ridge shape from substantially the front end of the horizontal surface to substantially the rear end of the inclined surface.
Description
Technical Field
The present disclosure relates to a toilet seat having a water repellent function for preventing adhesion of water droplets, and a toilet seat apparatus having the same.
Background
Conventionally, such a toilet seat has the following structure: by forming a cylindrical fine projection on the entire back surface of the toilet seat, the contact angle between the tip of the projection and water is increased, thereby providing a water repellent function (see, for example, 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, a flat surface portion 3 on the front side of the toilet seat 1 and an inclined portion 4 on the rear side of the toilet seat 1 are integrally formed on the back surface 2 of the toilet seat 1, and a protrusion 5 as shown in fig. 9B is formed over substantially the entire surface of the flat surface portion 3 and the inclined portion 4.
As shown in fig. 9B, the protrusion 5 is substantially cylindrical, and the tip is formed in a substantially hemispherical shape. The protrusions 5 have 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 protrusions 5 was 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 a step, not at the same height, in consideration of the mold-releasing direction of the mold at the time of molding. In such a case, the contact angle between the tip end of the protrusion 5 and water cannot be maintained at an appropriate angle, which causes a problem of a decrease in water repellency.

As shown in fig. 4 and 6, the toilet seat 300 is configured by, as main components, an upper toilet seat case 310 integrally molded from a resin material mainly made of polypropylene, a toilet seat heater 330 having a soaking plate made of aluminum foil and heating wires (not shown) disposed thereon, and a lower toilet seat case 320 integrally molded from a resin material mainly made of polypropylene. In the toilet seat 300 in its finished state, the inner and outer peripheries of the upper and lower toilet seat cases 310 and 320 are engaged with each other to form a ring shape having 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 constituting the body portion 301, which is formed in a substantially elliptical ring shape, and an upper support portion 312 constituting the support portion 302, which protrudes obliquely upward from a rear end portion of the seating portion 311.
As shown in fig. 6, the upper toilet seat case 310 is formed such that the cross section of the seating part 311 has a substantially mountain shape. The upper surface of the seating portion 311 is formed into a gentle curved surface suitable for seating. The inner and outer peripheries of the seating portion 311 are bent downward, and an inner peripheral edge and an outer peripheral edge that are substantially perpendicular to each other are formed at a distal end portion thereof.
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 seat case 320 is formed in a substantially elliptical ring shape having substantially the same shape as the seating portion 311 of the upper 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 tip end portion thereof.

The toilet seat heater 330 is adhesively fixed to the inner surface of the upper toilet seat case 310.
A thermistor as a temperature detection member and a thermostat as an overheating prevention member, which are not shown, are provided on the surface of the soaking plate. The heating wire, the thermistor and the thermostat are connected by a lead.
< 3 > structure of water repellent treatment part
As shown in fig. 5, the lower surface of the lower toilet seat case 320 is integrally formed by continuously connecting a horizontal portion 323 corresponding to the lower body portion 321 and an inclined portion 324 corresponding to the lower support portion 322. The horizontal portion 323 and the switching portion 325 of the inclined portion 324 are connected by a curved surface arranged substantially linearly at the rear of the lower toilet seat case 320.
A water repellent treatment section 340 is formed substantially over the entire surfaces of the horizontal section 323 and the inclined section 324. Further, a flat outer peripheral edge 351 and an inner peripheral edge 352 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 section 340, respectively (see fig. 5).
In the water-repellent treatment section 340, micron-order fine irregularities are continuously formed in a substantially linear shape so as to form a ridge line from substantially the front end of the horizontal section 323 to substantially the rear end of the inclined section 324. More specifically, in the water repellent treatment section 340, a convex shape and a groove shape are formed so that a ridge line is formed along a direction perpendicular to the switching section 325.
With such a configuration, when the uneven shape having the same shape is formed by injection molding in the horizontal portion 323 and the inclined portion 324 having different angles, the mold release direction of the mold during molding can be made uniform, and thus the mold manufacturing and the molding operation can be simplified.
Fig. 7 is a schematic view showing details of the D portion 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 portion of the concave portion 342 of the water-repellent treatment portion 340 is formed substantially flat. 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 a 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 having the above dimensions, the tip end portion of the convex portion 341 is formed at substantially 45 degrees. The angle of the tip of the convex portion 341 is preferably approximately 45 degrees to approximately 70 degrees. The height H of the convex portion 341 is preferably 10 μm or more from the viewpoint of water repellency, and the height H of the convex portion 341 is preferably 50 μm or less from the viewpoint of strength and the like.
The width M of the bottom side of the recess 342 of the water-repellent treatment section 340 is formed to be approximately 15 μ M. These uneven shapes of the water repellent treatment section 340 are such that the pitch N between the tip ends of the adjacent convex sections 341 becomes approximately 33 μm. The uneven shape is formed over the entire surface of the water repellent treatment section 340. The pitch N of the uneven 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 this structure, the effect of suppressing deformation or breakage of the convex portion 341 during use of the toilet seat 300 can be obtained.
< 4 > effect of water-repellent treatment section
Fig. 8A is a schematic diagram illustrating the contact angle of the surface of the substrate with the outer surface of a water droplet. Fig. 8B is a schematic diagram illustrating the roll-off angle of a water droplet on a substrate.
When water is applied to water repellent treatment portion 340 having the above-described structure by scattering of urine, washing water, or the like, the water drops on the surface of 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 droplets fall from the surface of the water-repellent treatment portion 340 in accordance with the tilt angle.
For example, when urine or washing water is applied to the water repellent treatment unit 340 in a state where the toilet seat 300 is standing up, the urine or washing water forms small water droplets, slides down along the irregularities of the water repellent treatment unit 340, and falls into the toilet 110.
In general, as an index for evaluating the water repellency, evaluation was performed based on a contact angle E as shown in fig. 8A and a roll-off angle F as shown in fig. 8B. That is, the larger the contact angle E and the smaller the roll-off angle F, 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 more easily the substrate 360 and the water droplet are attached to each other, and the closer the contact angle is to 180 degrees, the more difficult the water droplet is attached to the substrate 360.
As shown in fig. 8B, the roll-off angle F is an angle at which the base 360 to which the water droplets are attached is gradually inclined 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 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 water droplets to separate from the substrate 360.
In the case of a polypropylene material which is not subjected to water repellent treatment and is molded in general, the contact angle E is about 90 degrees and the roll-off angle F is 90 degrees or more.
On the other hand, the water repellent treatment section 340 of the present embodiment can exhibit water repellency such that the contact angle E is 150 degrees or more and the roll-off angle F is 30 degrees or less.
In addition, the water-repellent treatment section 340 of the present embodiment has fine ridge-like irregularities continuously formed in a substantially linear shape from substantially the front end of the horizontal section 323 to substantially the rear end of the inclined section 324. With this configuration, the mold releasing direction of the mold can be uniform during molding. This simplifies the manufacturing and molding operations of the mold, and can provide the toilet seat 300 having excellent water repellency at low cost.
In particular, by forming the convex portions 341 so that the cross-sectional shape thereof becomes substantially triangular, the water repellency can be further improved. Further, 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 becomes easy, and deformation of the molded article can be suppressed.
The water-repellent treatment section 340 of the present embodiment is configured to have a continuous ridge shape. With such a configuration, when an attached matter or dirt adheres to the water-repellent treatment section 340, cleaning by wiping is facilitated. Further, with such a structure, an effect of suppressing abrasion and deformation of the convex portion 341 can be obtained, and durability can be improved.
In the present embodiment, the tip end portion of the convex portion 341 of the water-repellent treatment portion 340 is 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 this configuration, the convex portion 341 of the water-repellent treatment portion 340 can be prevented from being deformed or broken during use of the toilet seat 300.
In the present embodiment, the cross-sectional shape of the convex portion 341 is a simple triangle, but the present invention is not limited to this, and for example, the convex portion may have a two-step shape in which the tip portion is formed to have an acute angle and the portion on the opposite side to the tip portion is formed to have 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 convex portion 341 is a substantially triangular shape, but the present invention is not limited thereto, and may be a substantially circular arc shape, a substantially trapezoidal shape, or a combination of these shapes.
