Description

  The present invention relates to a toilet seat device, and more particularly to a toilet seat device provided with a toilet seat characterized by a back surface shape.

  In a toilet seat apparatus such as a warm water washing toilet seat provided in a toilet bowl, the shape may be designed with the intention of improving the cleaning performance and design. For example, in Patent Document 1, a toilet seat connecting portion of a toilet seat that is rotatably connected to an apparatus main body including a local cleaning device is disposed on a side of the side surface of the apparatus main body, and constitutes an outer surface of the apparatus main body. Among these, the cleaning property of the facing surface facing the upper space of the bowl provided in the toilet bowl is improved. Moreover, in patent document 2, in order to improve the cleaning property of the sealing material which prevents the penetration | invasion of the sewage between the casing which incorporates a functional component, and a toilet bowl, and improving the cleanability of the clearance gap part, the front side of a casing is placed in the toilet bowl. It is described that an elevating apparatus is provided that lifts the sealing material provided on at least one of the upper surface of the toilet and the lower surface of the casing from the other of the upper surface of the toilet and the lower surface of the casing. In Patent Document 3, in order to improve the design of the toilet seat device, the main body is formed so that the longitudinal section is substantially triangular, the toilet lid is supported by a support portion in the vicinity of the apex, and the toilet lid is closed. A configuration is described in which the main body is hidden behind the toilet lid.

  According to the methods as described in Patent Documents 1 to 3 above, the toilet seat itself is improved, although the face-to-face, the gap between the casing and the toilet, and the cleanability and design of the joint between the toilet lid and the main body are improved. This does not improve the cleanability and design of the product. As shown in FIGS. 5 and 6, in the conventional general toilet seat device 90, the contact between the toilet seat 92 and the toilet bowl 9 is stabilized, and a clearance is provided between the toilet seat 9 and the toilet seat 92 from the closed state is provided. For the purpose of facilitating the opening operation, four foot portions 92a made of an elastic body such as rubber are provided on the back side surface of the toilet seat 92 so as to protrude. The toilet seat 92 contacts the toilet bowl 9 at the foot portion 92a. However, by having such a foot portion 92a, dirt and dust are likely to accumulate at the boundary between the toilet seat body 92b and the foot portion 92a. Further, the foot portion 92a easily obstructs a cleaning operation such as wiping the back side surface of the toilet seat 92, and reduces the cleanability of the back side surface of the toilet seat 92. The back side surface of the toilet seat 9 is a part that is very easily contaminated by dirt and water splashing, and it is important that the toilet seat 9 has high cleanability. Furthermore, the presence of the foot portion 92a also reduces the design of the toilet seat 92.

  The problem to be solved by the present invention is to provide a toilet seat device that is excellent in cleanability and design of the back side of the toilet seat.

  In order to solve the above-mentioned problems, a toilet seat device according to the present invention is a toilet seat device having a toilet seat that is attached to the upper surface of the toilet bowl so as to be opened and closed. And a rear contact portion disposed rearward of the front contact portion, the front contact portion and the rear contact portion project in a direction toward the toilet side with the toilet seat closed, The gist is that the entire back side surface including the front contact portion and the rear contact portion is formed of a gently curved surface having no corners.

  Here, the number of the front contact portion is one, provided at the center in the width direction of the front end portion of the toilet seat, and the number of the rear contact portions is two, provided at mutually synonymous positions in the width direction of the toilet seat. Is preferred.

  Moreover, it is good for the back side surface of the said toilet seat to form the recessed part between the said front contact part and the said back contact part.

  The front contact portion and the rear contact portion may be formed separately from the toilet seat body and attached to the toilet seat body.

  In the toilet seat device according to the invention, the toilet seat comes into contact with the toilet bowl at the front contact portion and the rear contact portion. The entire back side surface of the toilet seat including the front contact portion and the rear contact portion itself and the boundary between the front contact portion and the rear contact portion and the other portions have a gentle shape without corners. Dirt and dust are likely to accumulate in such corner portions, and the presence of the corners hinders cleaning of the back side surface of the toilet seat by wiping or the like. By not having such a corner structure, the toilet seat device is excellent in cleanability. Further, the back side surface of the toilet seat is a gently curved surface having no angular structure, and the curved shape gives high designability.

  Here, when there is one front contact portion and is provided at the center in the width direction of the front end portion of the toilet seat, and two rear contact portions are provided at mutually synonymous positions in the width direction of the toilet seat, Is in contact with the toilet bowl at three points, and the contact position is symmetrical with respect to the width direction of the toilet seat, the contact surface between the toilet seat and the toilet bowl is stabilized.

  Further, when a recess is formed between the front contact portion and the rear contact portion on the back side surface of the toilet seat, the front contact portion and the rear contact portion are made while making the shape of the entire back side surface very gentle. Can be secured. This further improves the cleanability and design of the back side of the toilet seat.

  When the front contact portion and the rear contact portion are formed separately from the toilet seat body and attached to the toilet seat body, the front contact portion and the rear contact portion can be easily formed. Moreover, the freedom degree regarding those materials and shapes becomes high.

  Hereinafter, a toilet seat device according to an embodiment of the present invention will be described in detail with reference to the drawings. In the present specification, the front and rear, the left and right (width direction), and the up and down directions correspond to the directions for the user seated on the toilet seat in the closed state.

  A toilet seat device 1 according to an embodiment of the present invention shown in FIGS. 1 to 3 includes a toilet seat 2, a toilet lid 3, and a device accommodating portion 4. The toilet seat device 1 is formed as a unit on the upper surface of the toilet 9. Installed. The device housing unit 4 incorporates components and control units of various devices such as a warm water cleaning device that ejects warm water for local human body cleaning and a warm air drying device that generates warm air for drying. The toilet seat 2 serves as a seating portion, and the toilet lid 3 covers the upper portion of the toilet seat 2. The toilet seat 2 and the toilet lid 3 are supported in front of the device accommodating portion 4 so as to be opened and closed independently by rotation. Here, with respect to the toilet seat 2, the open state is a state in which the toilet seat 2 is turned upward as shown in FIG. 2, and the closed state is a state in which the toilet seat 2 is rotated downward as shown in FIGS. The state which moved and was made to contact the toilet bowl 9 is shown.

  This toilet seat device 1 is characterized by the shape of the back side surface 21 of the toilet seat 2 exposed when the toilet seat 2 is opened. A front contact portion 22 and rear contact portions 23 and 23 are provided on the back side surface 21 of the toilet seat 2. The front contact part 22 and the rear contact parts 23, 23 swell and project in the direction (downward) of the toilet bowl 9 in the closed state. And the recessed parts 24 and 24 which were depressed above in the closed state are formed in the site | part between the front contact part 22 and the back contact parts 23 and 23. FIG.

  The back side surface 21 of the toilet seat 2 has a gentle (gradual) curved surface including a portion where the front contact portion 22, the rear contact portions 23 and 23, and the recesses 24 and 24 are formed. Here, the gentle curved surface is a curved surface having no corners. A corner is a part where the inclination of a surface changes discontinuously. For example, an intersection line (ridge line) formed at a part where a plane and a plane intersect or a part where a plane and a curved surface intersect, and chamfering on them. It is rounded to the extent that it has been applied. In other words, a straight line connecting any two points on the back side surface 21 including the front contact portion 22, the rear contact portions 23 and 23, and the concave portions 24 and 24 does not have a refraction point. A refraction point is an apex-shaped bend in which the slope changes discontinuously, for example, the intersection of a straight line and a straight line or the intersection of a straight line and a curve, and rounded to the extent that they are chamfered It is. 2 to 4, for ease of understanding, the gentle uneven shape on the back side surface 21 of the toilet seat 2 is exaggerated, the protruding shapes of the front contact portion 22 and the rear contact portion 23, The depressed shape is shown with a height difference larger than the actual height.

  Only one front contact portion 22 is formed in front of the front end portion of the toilet seat 2, that is, the substantially oval opening 25. The front contact portion 22 has a vertex on a center line C that bisects the width direction of the toilet seat 2 and is formed symmetrically with respect to the center line C. The two rear contact portions 23 and 23 are formed at the rear end portion of the toilet seat 2. The two rear contact portions 23 and 23 are formed on both sides of the opening 25 symmetrically with respect to the center line C.

As shown in FIG. 3, when the toilet seat 2 is closed, the toilet seat 2 comes into contact with the toilet bowl 9 at the tops of the front contact portion 22 and the rear contact portions 23 and 23. And a clearance gap is formed between the site | part on the back side surface 21 of the toilet seat 2 other than those, and the toilet bowl 9. FIG.

  In the toilet seat device 1, the back side surface 21 of the toilet seat 2 is formed with a smooth curved surface, so that the cleanability of the back side surface 21 of the toilet seat 2 is enhanced. The back side surface 21 of the toilet seat 2 is a portion that is very easily contaminated due to splashes of dirt, washing water, and the like. If corners are formed on the back side surface 21, dirt and dust are accumulated at the corner portions. It becomes easy. Further, when the back side surface 21 of the toilet seat 2 is cleaned by wiping or the like, a catch is generated at an excessive portion, and the presence of corners prevents smooth wiping of the back side surface 21. In this way, the corners deteriorate the hygiene and cleaning properties of the back side surface 21 of the toilet seat 2. Further, wiping residue is likely to occur at the corners. Such corners are, for example, the boundary between the contact surface 92c and the side surface 92d of the toilet portion 9a of the foot portion 92a on the back side surface of the toilet seat 92 of the conventional toilet seat device shown in FIGS. , Formed at the joint between the foot portion 92a and the main body portion 92b. However, in the toilet seat device 1, since the rear side surface 21 of the toilet seat 2 does not have such corners, it is unlikely that the toilet seat device 1 concentrates and accumulates on a site with dirt or dust. Further, along the gentle curved surface shape, the back side surface 21 can be smoothly wiped with cloth or paper, and the wiping work is not hindered by the corners, so that the cleaning property is improved.

  Furthermore, the back side surface 21 of the toilet seat 2 is not provided with a concavo-convex structure having discontinuous corners, and is formed in a flowing curved shape, thereby giving high designability. The back side surface 21 of the toilet seat 2 is a part that is visually recognized by the user when the toilet seat 2 is in an open state during men's use or cleaning, and it is important to improve the design.

  The front contact portion 22 and the rear contact portions 23, 23 have a role of stabilizing the placement of the toilet seat 2 on the toilet bowl 9 by contacting the toilet bowl 9 when the toilet seat 2 is closed. In addition, by providing a gap between the toilet seat 2 and the toilet bowl 9, it has a role of facilitating manual opening operation from the closed state of the toilet seat 2.

  In the toilet seat apparatus 1, a total of three front contact portions 22 and rear contact portions 23, 23 that come into contact with the toilet bowl 9 are formed, and one plane is defined by these, so that four or more contact portions are provided. Therefore, the toilet seat 2 is stabilized on the toilet bowl 9 in the closed state as compared with the case where the toilet seat 9 is contacted. In addition, since the front contact portion 22 and the rear contact portions 23 and 23 are disposed symmetrically with respect to the center line C and are disposed at the front end portion and the rear end portion of the toilet seat 2, the stability of the toilet seat 2 is further increased. It is high.

  However, the number and arrangement of the front contact portion 22 and the rear contact portions 23, 23 are not necessarily limited to those described above. For example, in the toilet seat device 1 ′ according to the modification shown in FIG. 4, the two front contact portions 22 and 22 are formed symmetrically in the vicinity of the front end portion of the toilet seat 2 with the center line C interposed therebetween.

  Moreover, in the toilet seat 2 of the toilet seat apparatus 1, although the recessed parts 24 and 24 between the front contact part 22 and the back contact parts 23 and 23 are not necessary, it is forming the recessed parts 24 and 24. The front contact portion 22 and the rear contact portions 23 and 23 having a protruding height can be formed by gentler curved surfaces. Thereby, the cleanability and design of the back side surface 21 of the toilet seat 2 are further enhanced.

  Even if the front contact portion 22 and the rear contact portions 23, 23 are formed integrally with the toilet seat body (the portion excluding the front contact portion 22 and the rear contact portions 23, 23 of the toilet seat 2), the front contact portion 22 and the rear contact portions 23, 23 are formed separately. It may be attached to. When formed integrally, a joint part does not occur between the toilet seat main body, the front contact portion 22 and the rear contact portions 23, 23, and the cleanability and design of the back side surface 21 of the toilet seat 2 are further enhanced. On the other hand, when it forms and attaches separately, it is suitable at the point from which the freedom degree of the shape, material, arrangement | positioning, etc. of the front contact part 22 and the back contact parts 23 and 23 becomes high.

  Moreover, the front contact part 22 and the back contact parts 23 and 23 may be formed with the same material as a toilet seat main body, or may be formed with a different material. In the case of forming with a different material, it is preferable to form it with an elastic material such as rubber so as to give a cushioning action to soften impact and collision sound between the toilet seat 2 and the toilet bowl 9. In order to form the front contact portion 22 and the rear contact portions 23 and 23 integrally with the toilet seat body using different materials, for example, insert molding may be used. The front contact portion 22 and the rear contact portions 23, 23 may be formed of different materials. Alternatively, one of the front contact portion 22 and the rear contact portions 23, 23 may be formed integrally with the toilet seat body, and the other may be formed separately and attached. For example, it is conceivable that the rear contact portions 23 and 23 are integrally formed of the same resin material as that of the toilet seat body, and the front contact portion 22 is separately formed of an elastic material.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said Example at all, A various change is possible in the range which does not deviate from the summary of this invention. For example, the toilet seat device does not need to be a so-called warm water flush toilet seat having various devices and functions as in the toilet seat device 1 (1 ′), and has various devices and functions, and the toilet seat 2 (and the toilet lid 3). It may be an old simple toilet seat equipped only with Further, the configuration of the contact portions 22 and 23 and the shape of the back side surface 21 of the toilet seat 2 as described above can be diverted to the inner side surface of the toilet lid 3 (the surface facing the toilet seat 2).
