Description

  The present invention relates to a toilet device in a toilet room, and particularly relates to a structure suitable for cleaning a toilet and a toilet device.

  Conventionally, sewage enters and adheres to the slight gap between the lower surface of the toilet apparatus casing and the upper surface of the toilet bowl, and the area of the lower surface of the casing facing the toilet bowl opening due to rebounding and scattering of defecation and urine. Cleaning was needed.

Therefore, as shown in FIG. 8 (a), the one provided with an arc-shaped protruding wall 10 that protrudes inward from the lower surface of the casing 6 where the opening of the toilet bowl 2 and the lower surface of the casing 6 overlap and covers the upper part of the inner surface of the toilet bowl 2 is provided. Yes (see Patent Document 1). This prevents sewage due to rebound or splattering of defecation and urine from entering the slight gap 7 between the lower surface of the toilet device 1 and the upper surface of the toilet 2 by the protruding wall 10.
In such a case, the toilet bowl 2 is generally made of earthenware, and the dimensional tolerance of the earthenware is larger than that of metal or resin. Therefore, depending on the dimensions of the mounting portion of the toilet device 1 and the toilet device 2, the size from the protruding wall 10 provided on the lower surface of the toilet device 1 to the upper surface of the inner surface of the toilet device 2 may increase, and sewage may enter from the gap 11. .
In FIG. 8A, a rim 12 is formed at the upper rear of the inner surface of the toilet 2 and is folded inward of the toilet 2, but when there is no folding as shown in FIG. 8B, for example, The sewage rushes along the rear of the opening, easily enters the slight gap 11 from the protruding wall 10 to the upper part of the inner surface of the toilet 2, and the sewage reaches the gap 7 between the lower surface of the toilet device 1 and the upper surface of the toilet 2. There is a possibility that.

Further, as shown in FIG. 9, there is one provided with a detachable panel 13 that is detachable on the front surface of the casing 6 (see Patent Document 2). Thereby, by removing the detachable panel 13, the upper surface of the toilet bowl 2 can be cleaned and the entire detachable panel 13 can be washed with water.
In such a case, since a gap is formed between the casing 6 and the detachable panel 13, for example, a male standing urine is released from the front upper side of the toilet 2, and the aim is removed and small water covers the front of the casing 6. If this happens, small water may enter through the gap and reach the inside of the casing 6. In addition, in order to make the detachable panel 13 detachable, it is difficult to arrange the connecting parts with the inside of the casing 6 in the space surrounded by the detachable panel 13, so a lot of dead space is generated and a compact storage design is achieved. There is a problem that the casing 6 becomes large and the refreshing design is impaired.

Further, as shown in FIG. 10, by raising the toilet device 1 main body, the clearance 7 between the lower surface of the toilet device 1 and the upper surface of the toilet 2 is exposed, and a slight gap between the lower surface of the toilet device 1 and the upper surface of the toilet 2 is exposed. 7 and the area of the lower surface of the casing 6 facing the opening of the toilet 2 can be cleaned (see, for example, Patent Document 3).
In such a case, when the toilet device 1 is raised manually, the toilet device 1 having multiple functions is heavy, and it is difficult for elderly people or people suffering from back pain to lift the toilet device 1. It was. In addition, there is a mechanism that has a lock mechanism at the raised position even when it is raised, but when the lock is incomplete, there is a problem that the lock is released and a finger is caught between the lower surface of the toilet device 1 and the upper surface of the toilet device 2. It was. Or when raising the toilet device 1 automatically, since it is necessary to provide the raising / lowering mechanism 14, such as a motor, in the toilet device 1, a compact storage design becomes difficult, and the casing 6 becomes large and the refreshing design property is impaired. Therefore, there is a problem that cleaning of the toilet device 1 main body becomes troublesome.
Japanese Patent No. 2516985 (page 3, FIG. 1) Japanese Patent No. 3070199 (page 3, FIG. 1) Japanese Patent No. 3248119 (page 7, Fig. 1)

  The present invention has been made in order to solve the above-mentioned problems, and an object of the present invention is to allow sewage due to rebounding or splattering of stool or urine to enter a slight gap between the casing lower surface of the toilet device and the toilet upper surface. To provide a toilet device that prevents sewage from adhering to the lower surface of the casing facing the toilet opening, has good cleanability, and does not impair the appearance of clean design. Is.

According to the first aspect of the present invention, the cover member includes the seal portion and a substantially flat cover portion that is attached to the lower surface of the casing and covers a region of the lower surface of the casing that overlaps the toilet opening. The surfaces of the seal part and the cover part are connected flush with each other. As a result, when there is unevenness in the area of the casing lower surface that overlaps the toilet opening, it is difficult to clean this part, but by covering the area of the casing lower surface that overlaps with the toilet opening with a cover, Since it adheres to a substantially flat cover, cleaning becomes easy. In addition, since the seal member and the substantially flat cover member are smoothly connected in a flush manner, the cover member, the seal member, and the back of the toilet opening that are smoothly connected can be quickly wiped during cleaning. The improvement of property can be aimed at. Furthermore, since the cover member is placed in the area of the lower surface of the casing of the toilet device that overlaps the toilet opening, the design of the toilet device is ensured by placing it in a place that is inconspicuous from the use position of the toilet device. Is possible.

According to a second aspect of the present invention, the seal portion has a substantially arc shape on the outer periphery, and a convex portion is provided along the substantially arc shape, and the convex portion is a toilet opening below the upper surface of the toilet bowl. It is characterized by contacting with the inside. As a result, when the inside of the toilet bowl is sealed by the reaction force of the elastic body, the adhesion between the seal portion and the inside of the toilet bowl can be improved, and the sewage rebounds, splashes and runs up in the toilet bowl can be more effective. Therefore, it is possible to prevent sewage from entering a slight gap between the lower surface of the casing of the toilet device and the upper surface of the toilet. In addition, since the seal portion is an inclined surface in the toilet bowl opening, dirty water is less likely to collect than the seal at a flat portion like the conventional toilet upper surface.

According to a third aspect of the present invention, the cover member is movably or detachably attached to the lower surface of the casing. Thereby, by separating the cover member from the seal location in the toilet opening, the sewage remaining slightly in the seal location can be cleaned, and the source of bad odor can be removed. Further, even when a gap is generated between the front upper part of the cover member and the front lower surface of the casing and some sewage enters, cleaning can be performed by taking out the cover member.

According to a fourth aspect of the present invention, the seal portion is movably or detachably attached to the cover portion. Thereby, by separating the seal portion from the seal portion in the toilet opening, the sewage slightly remaining in the seal portion can be cleaned, and the source of bad odor can be removed.

According to a fifth aspect of the present invention, the seal portion is integral with the cover portion. This eliminates the need for connection between the seal portion and the cover portion, and does not generate a gap due to the connection, which is more hygienic.

According to a sixth aspect of the present invention, a protrusion extending downward from the casing is provided so as to cover a gap between a front upper portion of the cover member and a front lower surface of the casing. As a result, even when a gap is generated between the front upper portion of the cover member and the front lower surface of the casing, the sewage from the front can be provided by providing a protrusion extending downward from the casing so as to cover the gap between the cover member and the lower surface of the casing. Intrusion can be prevented.

According to a seventh aspect of the present invention, the cover member has a surface layer having antifouling properties or antibacterial properties . Thus, by applying, for example, an antifouling material or an antibacterial material to the surface of the cover member, dirt is less likely to adhere to the cover member and it is easy to wash away, thereby facilitating cleaning. In addition, it is possible to keep bacteria clean and to keep them clean.

  According to the present invention, it is possible to prevent sewage from entering the slight clearance between the lower surface of the casing of the toilet device and the upper surface of the toilet, such as bouncing or splashing of stool or urine, and the lower surface of the casing facing the toilet opening. This prevents the sewage from adhering to the surface, has good cleaning properties, and can ensure a clean design on the appearance.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1A is a top view showing the arrangement of the cover member 3 of the present invention with respect to the toilet device 1 main body and the toilet 2 (the toilet lid 4 and the toilet seat 5 are not shown), and FIG. Is a sectional view of the center. The cover member 3 is disposed in the opening of the toilet 2 and below the casing 6, and is attached to the lower surface of the casing 6.

FIG. 2 is an enlarged view of the vicinity of the location where the cover member 3 is attached in FIG. 1B, FIG. 3A is a top view of the cover member 3 alone, and FIG.
When the seal portion 3a of the cover member 3 is attached to the lower surface of the casing 6, the tip of the seal portion 3a is pressed against the rearward inside opening of the toilet bowl 2 (the rear surface of the toilet bowl), and downward as shown in FIG. It will be warped. Further, the cover portion 3c connected to the seal portion 3a has a substantially flat shape, and is disposed at a position closing the region facing the toilet 2 opening on the lower surface of the casing 6, and is located above the cover portion 3c. The four claw portions 3d extending in the direction are fitted into the attachment holes 6d provided on the lower surface of the casing 6 to be attached to the lower surface of the casing 6.

Here, the sealing member 3a is made of an elastic body, and as shown in FIG. 7, the toilet 2 in all the positional relationships taking into account the dimensional tolerance of the mounting positions of the toilet device 1 and the toilet 2 and the size of the play due to the mounting. It is designed to be able to seal the back of the opening.
At this time, when the cover member 3 is attached to the lower surface of the casing 6, the seal portion 3 a is warped downward, and the reaction force of the seal portion 3 a acts to press the convex portion 3 b to the rear of the toilet 2 opening. It becomes possible to seal the back of the toilet 2 opening. Accordingly, it is possible to prevent sewage such as defecation and urine from entering the gap 7 between the lower surface of the casing 6 and the upper surface of the toilet 2 due to splashing, scattering, and running up.

At this time, since the seal portion is an inclined surface, dirty water is less likely to collect than the seal at a flat portion such as the upper surface of a conventional toilet bowl. Furthermore, when cleaning the conventional toilet bowl top seal, it was difficult to visually check the degree of dirt in the vicinity of the seal, and it was difficult to clean because it was not reachable. If the seal is in the rear of the opening, it is possible to easily check and clean the dirt near the seal location.
At this time, the cover member 3 is attached to the lower surface of the casing 6 by fitting four claw portions 3d extending upward to the lower surface of the casing 6, and is attachable to and detachable from the lower surface of the casing 6. In this case, a little sewage remains in the seal portion 2a, which is the connection between the rear of the toilet 2 opening and the convex portion 3b, but the sewage slightly left in the seal portion 2a by attaching and detaching the cover member 3 Can be wiped clean, eliminating the source of bad odor.

  At this time, since the cover 3c is arranged at a position that closes the area facing the toilet 2 opening in the lower surface of the casing 6, the area overlapping the toilet 2 opening in the lower surface of the casing 6 is uneven. Although it is difficult to clean this part, since the cover 3c covers the area of the lower surface of the casing 6 that overlaps the opening of the toilet 2, the sewage does not adhere to the lower surface of the casing 6 and the substantially flat cover 3c. Since it adheres to, it becomes easy to clean. Further, since the cover member 3 is attached to the lower surface of the casing 6, it is not conspicuous even during defecation and urination, and is not incorporated in the toilet device 1 body, so that it does not require a space in the toilet device 1 body and is compactly stored. Design is also easy, and the design of the toilet device 1 can be ensured.

  At this time, since the seal portion 3a and the cover portion 3c are smoothly connected and the seal portion 3a is in close contact with the back of the toilet 2 opening, the lower portion of the casing 6 and the back of the toilet 2 opening are cleaned. In this case, since it can be wiped off quickly, cleaning becomes easy.

  Here, in this embodiment, the cover member 3 is fitted to the claw portion 3d so as to be detachable from the casing 6. For example, as shown in FIG. 4, each of the upper side surface of the cover member 3 and the lower side of the casing 6 is provided. The slide grooves 3e and 6e may be provided in the front-rear direction so that the cover member 3 can be moved and removed from the casing 6 in the front-rear direction. Thus, the sewage adhering to the seal portion 2a can be wiped cleanly by exposing the seal portion 2a by separating the seal portion 3a from the rear side of the opening of the toilet 2, so that the source of bad odor can be eliminated.

Alternatively, the seal portion 3a may be movable from the cover portion 3c as shown in FIG. 5A, or the seal portion 3a may be detachable from the cover portion 3c as shown in FIG. 5B. In the case of Fig.5 (a), the hinge 3f is provided in the front upper part of the cover part 3c, and the seal | sticker part 3a can be rotated ahead from the hinge 3f center. Further, in the case of FIG. 5B, a protrusion 3g is provided at a connection portion of the seal portion 3a with the cover portion 3c, and is fitted into an insertion hole 3h provided at a connection portion of the cover portion 3c with the seal portion 3a. The seal portion 3a is detachable from the cover portion 3c. Thereby, the seal | sticker location 2a can be open | released and the same effect can be acquired.
Note that the moving or detachable connecting method of the seal portion 3a and the cover member 3c and the moving or detachable mounting method of the casing 6 and the cover member 3 of the present embodiment are one of specific examples. There are many methods, and the present invention is not limited to the above specific examples.
Furthermore, you may comprise integrally all the elements which comprise the cover member 3 with an elastic body (not shown). Thereby, the connection between the seal portion 3a and the cover portion 3c becomes unnecessary, and a gap due to the connection is not generated, so that it is more hygienic.

  Further, in this embodiment, as shown in FIG. 2, the gap 7 between the lower surface of the casing 6 and the upper surface of the toilet bowl 2 is completely closed by bringing the upper front portion of the cover portion 3 c into contact with the lower front surface of the casing 6. It is desirable to prevent sewage from entering the gap 7.

  However, there may be a situation in which the front lower surface of the casing 6 has irregularities, and the upper front portion of the cover portion 3c cannot be brought into contact with the lower front surface of the casing 6 and must be disposed in the immediate vicinity. In that case, there is a slight gap 8 between the front upper portion of the cover portion 3c and the front lower surface of the casing 6. For example, a male standing urine is released from the front upper side of the toilet 2, and the aim is removed and small water is generated. When it covers the vicinity of the front lower surface of the casing 6, there is a possibility that small water may directly enter the slight gap 8 between the upper front portion of the cover portion 3c and the lower front surface of the casing 6 from the front. In preparation for this case, in this embodiment, a protruding portion 9 extending downward from the casing 6 is provided so as to cover the gap 8 between the upper front portion of the cover portion 3c and the lower front surface of the casing 6. Accordingly, when the male standing urine is released from the front upper side of the toilet 2 and the aim is removed and the small water covers the vicinity of the front lower surface of the casing 6, the protruding portion 9 is formed on the lower surface of the cover member 3 and the casing 6. Small water can be prevented from entering the gap 8 and can be kept clean. In this case, since the cover member 3 can be attached to and detached from the toilet device 1 without providing the protruding portion 9, the cover member 3 may be removed to clean the gap 8, but by providing the protruding portion 9, The cleaning of the gap 8 becomes unnecessary.

  Here, it is desirable that the cover member 3 has a functional surface layer (not shown) on the lower surface to which dirty water adheres. By applying, for example, an antifouling material or an antibacterial material to the surface of the cover member 3, dirt is less likely to adhere to the cover member 3, and it is easy to wash away, so that the cover member 3 can be easily cleaned and bacteria Can be prevented and breeding can be kept clean.

  In addition, as shown in FIG. 6, water may be allowed to pass through the lower surface of the cover member 3, and the lower surface of the cover member 3 may be washed every time it is used. In the case of FIG. 6, the supplied water is injected into the pressure chamber 3 i connected to the lower surface of the casing 6. The water in the pressure chamber 3i is ejected from the slit 3j to the lower surface of the cover member 3, and the lower surface of the cover member 3 is washed. In this case, a signal of a device incorporated in the toilet device 1, for example, a human body detection sensor that detects whether the human body is near the toilet, a seating sensor that detects whether the human body is seated on the toilet seat, or a toilet bowl The lower surface of the cover member 3 may be automatically cleaned by using a signal or the like from a remote controller (not shown) that operates the apparatus 1 remotely.

Alternatively, a switch (not shown) for cleaning the cover member 3 is uniquely provided in the toilet device 1 or the remote controller, and the lower surface of the cover member 3 is cleaned by pressing the switch every time the toilet device 2 is cleaned or used. You may let them. Thereby, the trouble of cleaning the rear of the toilet 2 opening and the lower part of the casing 6 can be saved, and the rear of the toilet 2 opening and the lower part of the casing 6 can always be kept clean by a simple operation.
In addition, the water flow method to the lower surface of the cover member 3 of a present Example is one of the specific examples, There are many other methods, and it is not limited to the said specific example.
