Description

[Technical field]

[0001] The disclosed embodiments relate to a flush toilet. [Background technology]

[0002] Conventionally, in so-called floor-standing flush toilets that are installed on the floor, when the toilet body is fixed to the floor, for example, there is a type in which it is fixed to a fixing piece on the floor via a bolt that is inserted from the front of a mounting hole formed in the front part of the skirt part of the toilet body (for example, see paragraph 0002 and figure 12 of Patent Document 1).

[0003] Additionally, in the case of floor-standing flush toilets, when the toilet body is fixed to the floor surface, for example, it is fixed to a fixing piece on the floor surface via a bolt inserted from the side of a mounting hole formed in the side of the skirt part of the toilet body (for example, see paragraphs 0004-0007 and figures 7 and 8 of Patent Document 2). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Application Publication No. 11-140947 [Patent Document 2] Japanese Patent Application Publication No. 5-140978 Summary of the Invention [Problem to be solved by the invention]

[0005] In flush toilets, the rimless design of the toilet body makes it easier for urine to run up when the toilet is used, for example, and the urine may run down the side of the toilet body onto the floor and seep into the gap between the toilet body and the floor and into the surface where the toilet body is placed. If urine (sewage) seeps into the toilet body, it is difficult to remove with normal cleaning, and there is the possibility of causing bad odors. Ceramic toilet bodies in particular have large tolerances, so the gap between the toilet body and the floor is prone to becoming large.

[0006] In all of the above conventional flush toilets, it is difficult to tolerate tolerance variations when the toilet body is made of ceramic. Also, in all of the above conventional flush toilets, the mounting holes formed in the skirt part of the toilet body are visible to users, and even if the mounting holes are hidden with a sticker or decorative cap, for example, the design is diminished.

[0007] One aspect of the embodiment aims to provide a flush toilet that allows the toilet body to be installed on a floor surface while allowing for tolerance variations in the ceramic toilet body, and that can improve cleaning ease and design. [Means for solving the problem]

[0008] A flush toilet according to one embodiment has a bowl portion that receives waste, a drain trap portion that is connected to the bowl portion and discharges the waste received by the bowl portion, and a skirt portion that is arranged outside the side surfaces of the bowl portion and the drain trap portion, and is equipped with a ceramic toilet body that is placed on a floor surface, a functional portion that is arranged behind the bowl portion and has the function of controlling the discharge / stop of flushing water into the bowl portion, and a fixing portion for fixing the toilet body and the floor surface, the skirt portion has an outer wall portion that forms the outer surface of the skirt portion, and an inner wall portion that is arranged inside the outer wall portion with a space between it and the outer wall portion, and the fixing portion has a first adhesive member fixed to the inner wall portion side, a second adhesive member fixed to the floor surface side, and a vertical adjustment portion that moves at least one of the first adhesive member and the second adhesive member in the vertical direction toward the other.

[0009] When the toilet body is installed on the floor, the tolerance variation of the ceramic toilet body is large, so the gap between the toilet body and the floor surface is likely to become large, but with this configuration, the vertical adjustment part presses the first adhesive member and the second adhesive member, thereby making it possible to reduce the gap between the toilet body and the floor surface. In other words, the toilet body can be installed on the floor surface while allowing for the tolerance variation specific to the ceramic toilet body. In addition, sewage will not seep into the toilet body through the gap with the floor surface, improving cleanability and suppressing the generation of odors caused by sewage seeping into the toilet body.

[0010] Furthermore, with this configuration, there is no need to form holes in the toilet body to secure it to the floor surface, so sewage will not seep into the toilet body through these holes, improving cleaning ease and suppressing the generation of odors caused by sewage seeingping into the toilet body.

[0011] Furthermore, if holes are formed in the toilet body, they are visible to users and look bad even if they are hidden with a sticker or decorative cap; however, with this configuration, there are no holes in the toilet body, so the appearance is good and the design can be improved.

[0012] Furthermore, in the above flush toilet, the vertical adjustment portion is an elastic body that shrinks in the vertical direction after being fixed to the toilet body and the floor surface compared to before being fixed to the toilet body and the floor surface.

[0013] With this configuration, the tolerance variation in the vertical direction of the ceramic toilet body can be more reliably accommodated with a simple configuration.

[0014] Furthermore, in the above flush toilet, one of the first adhesive member and the second adhesive member is a magnet, and the other is a magnetic body.

[0015] According to such a configuration, after the toilet body is placed on the floor surface, it is possible to fine-tune the surface direction (planar direction) of the toilet body relative to the floor surface.

[0016] Furthermore, in the above flush toilet, the fixing portion is fixed to the inner wall portion by a rubber bushing and a bolt that is inserted into the rubber bushing.

[0017] With this configuration, the fixing portion can be easily fixed to the inner wall portion.

[0018] Furthermore, in the above flush toilet, the fixed portion is fixed in the vertical direction to the inner wall portion.

[0019] With this configuration, it is easy for an worker to see when installing the toilet body on the floor surface. For example, the worker can visually grasp the positional relationship between the fixing part and the inner wall part, making it easy to fix the fixing part to the inner wall part. Effect of the Invention

[0020] A flush toilet according to one aspect of the embodiment makes it possible to install the toilet body on the floor while allowing for tolerance variations in the ceramic toilet body, and also improves cleaning ease and design. [Brief description of the drawings]

[0022] Below, an embodiment of a flush toilet disclosed in the present application will be described in detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiment described below.

[0023] First Embodiment A flush toilet 1 pertaining to the first embodiment will be described with reference to Figures 1 to 4. Figure 1 is a schematic side view showing the flush toilet 1 pertaining to the first embodiment. Figure 2 is a schematic bottom view showing the flush toilet 1 pertaining to the first embodiment. Figure 3 is a cross-sectional view taken along line III-III in Figure 1. Figure 4 is an enlarged view of a portion of Figure 3. Note that Figures 3 and 4 show a front cross section of the toilet body 2, including the fixed part 4, which will be described later.

[0024] In addition, each figure may show a three-dimensional Cartesian coordinate system including a Z-axis with the positive direction being vertically upward (upward). For ease of explanation, the positive direction of the X-axis is defined as the left, the negative direction of the X-axis as the right, the positive direction of the Y-axis as the forward direction, and the negative direction of the Y-axis as the backward direction, and the X-axis direction is referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction.

[0025] As shown in Figures 1 and 2, the flush toilet 1 is a so-called floor-standing type, in which a toilet body 2 is placed on the floor surface FS of a toilet room, etc. The flushing method in the flush toilet 1 may be, for example, a siphon type, or another type such as a wash-down type.

[0026] The flush toilet 1 comprises a toilet body 2, a functional section 3, and a fixed section 4. The toilet body 2 is made of ceramic. The toilet body 2 comprises a bowl section 21, a water guide section 22, a drain trap section 23, and a skirt section 24.

[0027] Bowl portion 21 is a portion for receiving waste and is formed in a bowl shape. The bottom of bowl portion 21 serves as water storage portion 211 for storing a predetermined amount of water. Water storage portion 211 is connected to drain trap portion 23, which will be described later.

[0028] The toilet body 2 has, for example, a so-called rimless shape, with a wall rising approximately vertically above the bowl portion 21, i.e., on the upper edge of the toilet body 2. The toilet body 2 may have an annular rim portion provided above the bowl portion 21, i.e., on the upper edge of the toilet body 2.

[0029] The water conducting section 22 is formed, for example, behind the bowl section 21. The water conducting section 22 is a flow path for supplying flush water into the bowl section 21. The water conducting section 22 extends forward from a flush water supply port (not shown) in the toilet body 2.

[0030] As described above, drain trap portion 23 is connected to the bottom (retention portion 211) of bowl portion 21. Drain trap portion 23 discharges waste received by bowl portion 21. Drain trap portion 23 is a pipe extending rearward from bowl portion 21 so that waste in bowl portion 21 can be discharged.

[0031] Drain trap portion 23 includes upstream portion 231 and downstream portion 232. An upstream end portion (front end portion) of upstream portion 231 is connected to the bottom portion (pooling portion 211) of bowl portion 21. Upstream portion 251 is in communication with pooling portion 211 and is a pipe that, for example, descends toward the rear and then ascends.

[0032] The downstream section 232 is connected to the downstream end (rear end) of the upstream section 231. The downstream section 232 is a pipe that communicates with the rear end of the upstream section 231 and extends downward. The downstream section 252 is connected to an external pipe (not shown) via a drain socket 25, for example.

[0033] The skirt portion 24 is provided outside the side surfaces 21a, 23a of the bowl portion 21 and the drain trap portion 23. The skirt portion 24 covers substantially the entire periphery of the toilet body 2, and forms the outer surface of the toilet body 2.

[0034] As shown in Fig. 3, the skirt portion 24 includes an outer wall portion 241 and an inner wall portion 242. The outer wall portion 241 forms the outer surface of the skirt portion 24. In other words, the outer wall portion 241 forms the outer surface of the toilet body 2 (see Figs. 1 and 2). The inner wall portion 242 is provided on the inside of the outer wall portion 241. A space (hereinafter referred to as an internal space) S is formed between the outer wall portion 241 and the inner wall portion 242.

[0035] In this manner, the skirt portion 24 has a double-wall structure made up of the outer wall portion 241 and the inner wall portion 242. The skirt portion 24 has an internal space S between the outer wall portion 241 and the inner wall portion 242.

[0036] 1, the functional unit 3 is provided behind the bowl portion 21 by being stored in a storage section (not shown) in the toilet body 2, which is formed behind the bowl portion 21 of the toilet body 2. The functional unit 3 includes a function for controlling the discharge / stop of flush water supplied to the bowl portion 21. Note that the functional unit 3 may also include other functions, such as a function for controlling a toilet seat device (not shown) for washing the user's private parts.

[0037] As shown in Fig. 1, the fixing part 4 is a member for fixing the toilet body 2 to the floor surface FS. As shown in Figs. 1 and 2, the fixing part 4 is provided at the front part of the toilet body 2. The fixing part 4 is provided at the front part of the toilet body 2 by being attached to an attachment part 243 provided at the front part of the inner wall part 242. In this case, the fixing part 4 fixes the toilet body 2 and the floor surface FS at the front part of the toilet body 2.

[0038] For example, when the mounting portion 243 is provided at the center of the inner wall portion 242 in the fore-aft direction and on the left and right sides, the fixing portion 4 may be attached to the mounting portion 243, and may fix the toilet body 2 and the floor surface FS at the center of the toilet body 2 in the fore-aft direction and on the left and right sides.

[0039] 3, the fixing part 4 includes a first fixing part 41 and a second fixing part 42. The first fixing part 41 includes a case part 411, a rubber bushing 412, a bolt 413, a holding part 414, a movable part 415, a first adhesive member 416, and a vertical direction adjustment part 417.

[0040] The case part 411 is provided at the bottom of the toilet body 2 (see Figs. 1 and 2). The case part 411 is attached to the inner wall part 242 of the skirt part 24 at both left and right ends via rubber bushes 412 and bolts 413 described below.

[0041] Rubber bushing 412 is a cylindrical member made of, for example, rubber or thermoplastic elastomer, and has a through hole 412a in the longitudinal direction (vertical direction). Rubber bushing 412 has female thread portion 413b at the upper end portion to be screwed with the tip end portion of bolt 413 described later. Rubber bushing 412 has deformation portion 412c in the center in the longitudinal direction (vertical direction).

[0042] The rubber bushing 412 is inserted into the mounting hole 243a of the mounting portion 243 of the inner wall portion 242. The rubber bushing 412 fixes the case portion 411 to the mounting portion 243 by screwing the tip portion of a bolt 413 inserted into the through hole 412a from below the rubber bushing 412 into the female thread portion 413b.

[0043] In this case, by tightening the bolt 413, the rubber bush 412 contracts in the vertical direction, and the deformed portion 411c is crushed and spreads outward. When the deformed portion 411c spreads outward, the rubber bush 412 is fixed to the mounting hole 243a. As a result, the case portion 411 is fixed to the mounting portion 243 of the inner wall portion 242 in the vertical direction.

[0044] Holding portion 414 is housed in case portion 411. Holding portion 414 holds movable portion 415, which will be described later, so as to be movable in the up and down direction.

[0045] As described above, the movable portion 415 is held by the holding portion 414 so as to be movable in the up and down direction. The movable portion 415 is limited by the holding portion 414 to only be movable in the up and down direction, and movement in the left and right direction is restricted.

[0046] The first adhesive member 416 is provided on the bottom surface of the movable part 415. The first adhesive member 416 is, for example, a plate-shaped magnet. The first adhesive member 416 is fixed to the attachment part 243 of the inner wall part 242 by the case part 411 being fixed to the attachment part 243 of the inner wall part 242.

[0047] The up-down direction adjustment part 417 is provided in the space between the holding part 414 and the movable part 415. The up-down direction adjustment part 417 moves the movable part 415 downward in the up-down direction. In other words, the up-down direction adjustment part 417 moves the first adhesive member 416 downward in the up-down direction.

[0048] The vertical direction adjustment part 417 is an elastic body that contracts in the vertical direction after the toilet body 2 is fixed to the floor surface FS compared to before the toilet body 2 is fixed to the floor surface FS. The vertical direction adjustment part 417 is, for example, a compression coil spring.

[0049] The second fixing portion 42 includes a base portion 421, a fixing screw 422, and a second adhesive member 423. The base portion 421 is placed at a predetermined position on the floor surface FS. The base portion 421 is a plate-shaped member.

[0050] The base part 421 also has bent parts 421a formed so that both ends in the up-down direction and both ends in the left-right direction are bent and rise up approximately vertically. The bent parts 421a are inserted into grooves extending in the up-down direction formed in the case part 411 of the first fixed part 41 when the toilet body 2 is placed on the floor surface FS. By inserting the bent parts 421a of the base part 421 into the grooves of the case part 411, the up-down and left-right movement of the case part 411 is restricted.

[0051] The fixing screw 422 is screwed into the floor surface FS to fix the base part 421 to the floor surface FS.

[0052] The second adhesive member 423 is provided on the upper surface of the base portion 421. The second adhesive member 423 is, for example, a plate-shaped magnetic body, and is a metal such as iron or nickel that can be attached to a magnet. Note that "adhesion" refers to detachable adhesion of one part to the other. In addition to the magnet and magnetic body described above, "adhesion" includes adhesion such as hook-and-loop fasteners described below, or adhesion such as a gel mat and a plate-shaped resin member described below.

[0053] In the flush toilet 1 pertaining to the first embodiment, as shown in FIG. 4, when the toilet body 2 is placed on a floor surface FS, the fixing part 4 acts such that the vertical adjustment part 417 presses the first adhesive member 416 with a predetermined pressing force F towards the second adhesive member 423 provided on the floor surface FS.

[0054] When the toilet body 2 is installed on the floor surface FS, the tolerance variation of the ceramic toilet body 2 is large, so the gap between the toilet body 2 and the floor surface FS is likely to become large, but according to the first embodiment described above, the vertical adjustment part 417 presses the first adhesive member 416 and the second adhesive member 423 together, thereby making it possible to reduce the gap between the toilet body 2 and the floor surface FS. In other words, the toilet body 2 can be installed on the floor surface FS while allowing for the tolerance variation specific to the ceramic toilet body 2. In addition, sewage does not seep into the installation surface of the toilet body 2 with the floor surface FS through the gap with the floor surface FS, improving cleanability and suppressing the generation of odors caused by sewage seeping into the toilet body 2.

[0055] Furthermore, according to the first embodiment as described above, there is no need to form holes in the toilet body 2 for fixing it to the floor surface FS, so sewage will not seep into the toilet body 2 through these holes, improving cleaning ease and suppressing the generation of odors caused by sewage seeingping into the toilet body 2.

[0056] Furthermore, if holes were formed in the toilet body 2, they would be visible to users and would look bad even if the holes were covered with stickers or decorative caps. However, according to the first embodiment described above, there are no holes in the toilet body 2, so the appearance is good and the design can be improved.

[0057] Furthermore, according to the first embodiment described above, the vertical adjustment portion 417 is an elastic body that contracts in the vertical direction after the toilet body 2 and the floor surface FS are fixed, so that the vertical tolerance variation of the ceramic toilet body 2 can be more reliably tolerated with a simple configuration.

[0058] Furthermore, according to the first embodiment as described above, one of the first adhesive member 416 and the second adhesive member 423 is a magnet, and the other is a magnetic material, so that after the toilet body 2 is placed on the floor surface FS, it is possible to fine-tune the surface direction (planar direction) of the toilet body 2 relative to the floor surface FS.

[0059] Furthermore, according to the first embodiment as described above, since the fixing portion 4 is fixed to the attachment portion 243 of the inner wall portion 242 by the rubber bushing 412 and the bolt 413, the fixing portion 4 can be easily fixed to the inner wall portion 242.

[0060] Furthermore, according to the first embodiment as described above, the fixing part 4 is fixed in the vertical direction relative to the mounting part 243 of the inner wall part 242, which makes it easy for an worker to see when installing the toilet body 2 on the floor surface FS. For example, since an worker can visually grasp the positional relationship between the fixing part 4 and the mounting part 243 of the inner wall part 242, the fixing part 4 can be easily fixed to the inner wall part 242.

[0061] In the first embodiment described above, the first adhesive member 416 is a magnet and the second adhesive member 423 is a magnetic body, but the present invention is not limited to this and may be, for example, the first adhesive member 416 is a magnetic body and the second adhesive member 423 is a magnet. Also, for example, the first adhesive member 416 and the second adhesive member 423 may be magnets that can be adhered to each other.

[0062] <Second embodiment> Next, a flush toilet 1 (1A) pertaining to a second embodiment will be explained with reference to Figure 5. Figure 5 is a cross-sectional (front cross-sectional) view showing a fixing part 4 (4A) of a flush toilet 1 (1A) pertaining to the second embodiment.

[0063] 5 may also show a three-dimensional Cartesian coordinate system including a Z-axis with the positive direction being vertically upward (upward). In the following, for convenience of explanation, the positive direction of the X-axis is defined as the leftward direction, the negative direction of the X-axis as the rightward direction, the positive direction of the Y-axis as the forward direction, and the negative direction of the Y-axis as the backward direction, and the X-axis direction is referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction.

[0064] The second embodiment described below differs from the first embodiment in the configuration of the first adhesive member 416A and the second adhesive member 423A of the fixing portion 4 (4A), but the other configurations are the same. Therefore, in the following, the same or equivalent parts as those in the first embodiment are given the same reference numerals, and their description may be omitted.

[0065] As shown in Figure 5, the flush toilet 1A pertaining to the second embodiment is equipped with a fixed part 4A. The fixed part 4A is equipped with a first fixed part 41 (41A) and a second fixed part 42 (42A). The first fixed part 41A is equipped with a case part 411, a rubber bushing 412, a bolt 413, a retaining part 414, a movable part 415, a first adhesive member 416A, and a vertical adjustment part 417.

[0066] The case part 411 is provided at the bottom of the toilet body 2 (see Figs. 1 and 2). The case part 411 is attached to the inner wall part 242 of the skirt part 24 at both left and right ends via rubber bushes 412 and bolts 413 described below.

[0067] Rubber bushing 412 is a cylindrical member made of, for example, rubber or thermoplastic elastomer, and has a through hole 412a in the longitudinal direction (vertical direction). Rubber bushing 412 has female thread portion 413b at the upper end portion to be screwed with the tip end portion of bolt 413 described later. Rubber bushing 412 has deformation portion 412c in the center in the longitudinal direction (vertical direction).

[0068] The rubber bushing 412 is inserted into the mounting hole 243a of the mounting portion 243 of the inner wall portion 242. The rubber bushing 412 fixes the case portion 411 to the mounting portion 243 by screwing the tip portion of a bolt 413 inserted into the through hole 412a from below the rubber bushing 412 into the female thread portion 413b.

[0069] In this case, by tightening the bolt 413, the rubber bush 412 contracts in the vertical direction, and the deformed portion 411c is crushed and spreads outward. When the deformed portion 411c spreads outward, the rubber bush 412 is fixed to the mounting hole 243a. As a result, the case portion 411 is fixed to the mounting portion 243 of the inner wall portion 242 in the vertical direction.

[0070] Holding portion 414 is housed in case portion 411. Holding portion 414 holds movable portion 415, which will be described later, so as to be movable in the up and down direction.

[0071] As described above, the movable portion 415 is held by the holding portion 414 so as to be movable in the up and down direction. The movable portion 415 is limited by the holding portion 414 to only be movable in the up and down direction, and movement in the left and right direction is restricted.

[0072] The first adhesive member 416A is provided on the bottom surface of the movable portion 415. The first adhesive member 416A is one of the hook-and-loop fasteners. The first adhesive member 416A is fixed to the attachment portion 243 of the inner wall portion 242 by fixing the case portion 411 to the attachment portion 243 of the inner wall portion 242.

[0073] The up-down direction adjustment part 417 is provided in the space between the holding part 414 and the movable part 415. The up-down direction adjustment part 417 moves the movable part 415 downward in the up-down direction. In other words, the up-down direction adjustment part 417 moves the first adhesive member 416A downward in the up-down direction.

[0074] The vertical direction adjustment part 417 is an elastic body that contracts in the vertical direction after the toilet body 2 is fixed to the floor surface FS compared to before the toilet body 2 is fixed to the floor surface FS. The vertical direction adjustment part 417 is, for example, a compression coil spring.

[0075] The second fixing portion 42A includes a base portion 421, a fixing screw 422, and a second adhesive member 423A. The base portion 421 is disposed at a predetermined position on the floor surface FS. The base portion 421 is a plate-shaped member.

[0076] The base part 421 also has bent parts 421a formed so that both ends in the up-down direction and both ends in the left-right direction are bent and rise up approximately vertically. The bent parts 421a are inserted into grooves extending in the up-down direction formed in the case part 411 of the first fixed part 41A when the toilet body 2 is placed on the floor surface FS. By inserting the bent parts 421a of the base part 421 into the grooves of the case part 411, the up-down and left-right movement of the case part 411 is restricted.

[0077] The fixing screw 422 is screwed into the floor surface FS to fix the base part 421 to the floor surface FS.

[0078] The second adhesive member 423A is provided on the upper surface of the base portion 421. The second adhesive member 423A is a hook and loop fastener that can be adhered to one of the hook and loop fasteners that is the first adhesive member 416A.

[0079] In the flush toilet 1A pertaining to the second embodiment, when the toilet body 2 is placed on the floor surface FS, the fixing part 4A acts such that the vertical adjustment part 417 presses the first adhesive member 416A with a predetermined pressing force towards the second adhesive member 423A provided on the floor surface FS.

[0080] When the toilet body 2 is installed on the floor surface FS, the tolerance variation of the ceramic toilet body 2 is large, so the gap between the toilet body 2 and the floor surface FS is likely to become large, but according to the second embodiment described above, the vertical adjustment part 417 presses the first adhesive member 416A and the second adhesive member 423A together, thereby making it possible to reduce the gap between the toilet body 2 and the floor surface FS. In other words, the toilet body 2 can be installed on the floor surface FS while allowing for the tolerance variation specific to the ceramic toilet body 2. In addition, sewage does not seep into the installation surface of the toilet body 2 with the floor surface FS through the gap with the floor surface FS, improving cleanability and suppressing the generation of odors caused by sewage seeping into the toilet body 2.

[0081] Furthermore, according to the second embodiment as described above, there is no need to form holes in the toilet body 2 for fixing it to the floor surface FS, so sewage will not seep into the toilet body 2 through these holes, improving cleaning ease and suppressing the generation of odors caused by sewage seeingping into the toilet body 2.

[0082] Furthermore, if holes were formed in the toilet body 2, they would be visible to users and would look bad even if the holes were covered with stickers or decorative caps. However, according to the second embodiment described above, there are no holes in the toilet body 2, so the appearance is good and the design can be improved.

[0083] Furthermore, according to the second embodiment described above, the vertical adjustment portion 417 is an elastic body that contracts in the vertical direction after the toilet body 2 and the floor surface FS are fixed, so that the vertical tolerance variation of the ceramic toilet body 2 can be more reliably tolerated with a simple configuration.

[0084] Furthermore, according to the second embodiment as described above, since the fixing portion 4A is fixed to the attachment portion 243 of the inner wall portion 242 by the rubber bushing 412 and the bolt 413, the fixing portion 4A can be easily fixed to the inner wall portion 242.

[0085] Furthermore, according to the second embodiment as described above, the fixing portion 4A is fixed in the vertical direction relative to the mounting portion 243 of the inner wall portion 242, which makes it easy for an worker to see when installing the toilet body 2 on the floor surface FS. For example, since an worker can visually grasp the positional relationship between the fixing portion 4A and the mounting portion 243 of the inner wall portion 242, the fixing portion 4A can be easily fixed to the inner wall portion 242.

[0086] <Modification of the second embodiment> In the fixing portion 4A, the first fixing portion 41A may be composed of a first adhesive member 416A (one hook-and-loop fastener), and the second fixing portion 42A may be composed of a second adhesive member 423A (the other hook-and-loop fastener). In such a modified example, the first adhesive member 416A and the second adhesive member 423A can be pressed against each other by utilizing the elastic force in the vertical direction (plane direction) of the hook-and-loop fastener generated by the load when the toilet body 2 is placed on the floor surface FS. In such a modified example, the first adhesive member 416A and the second adhesive member 423A themselves become the vertical direction adjustment portion 417.

[0087] As a result, similar to the second embodiment described above, the vertical adjustment part 417 presses the first adhesive member 416A and the second adhesive member 423A together, thereby making it possible to reduce the gap between the toilet body 2 and the floor surface FS. In other words, the toilet body 2 can be installed on the floor surface FS while allowing for the tolerance variations that are unique to the ceramic toilet body 2. Furthermore, sewage will not seep into the installation surface of the toilet body 2 with the floor surface FS through the gap with the floor surface FS, improving cleanability and suppressing the generation of odors caused by sewage seeping into the toilet body 2.

[0088] Furthermore, according to the above-described modified example, there is no need to form holes in the toilet body 2 for fixing it to the floor surface FS, so sewage will not seep into the toilet body 2 through these holes, improving cleaning ease and suppressing the generation of odors caused by sewage seeingping into the toilet body 2.

[0089] Furthermore, if holes are formed in the toilet body 2, they will be visible to users and will look bad even if the holes are hidden with stickers or decorative caps. However, according to the modified example described above, there are no holes in the toilet body 2, so the appearance is good and the design can be improved.

[0090] <Third embodiment> Next, a flush toilet 1 (1B) pertaining to a third embodiment will be explained with reference to Figure 6. Figure 6 is a cross-sectional (front cross-sectional) view showing a fixing part 4 (4B) of a flush toilet 1 (1B) pertaining to the third embodiment.

[0091] 6 may also show a three-dimensional Cartesian coordinate system including a Z-axis with the positive direction being vertically upward (upward). In the following, for convenience of explanation, the positive direction of the X-axis is defined as the left, the negative direction of the X-axis as the right, the positive direction of the Y-axis as the front, and the negative direction of the Y-axis as the rear, and the X-axis direction is referred to as the left-right direction, the Y-axis direction as the front-back direction, and the Z-axis direction as the up-down direction.

[0092] The third embodiment described below differs from the first and second embodiments in the configuration of the first adhesive member 416B and the second adhesive member 423B of the fixing portion 4 (4B), but the other configurations are the same. Therefore, in the following, the same reference numerals are used for the same or equivalent parts as those in the first and second embodiments, and the description thereof may be omitted.

[0093] As shown in Figure 6, the flush toilet 1B pertaining to the third embodiment is equipped with a fixed part 4B. The fixed part 4B is equipped with a first fixed part 41 (41B) and a second fixed part 42 (42B). The first fixed part 41B is equipped with a case part 411, a rubber bushing 412, a bolt 413, a retaining part 414, a movable part 415, a first adhesive member 416B, and a vertical adjustment part 417.

[0094] The case part 411 is provided at the bottom of the toilet body 2 (see Figs. 1 and 2). The case part 411 is attached to the inner wall part 242 of the skirt part 24 at both left and right ends via rubber bushes 412 and bolts 413 described below.

[0095] Rubber bushing 412 is a cylindrical member made of, for example, rubber or thermoplastic elastomer, and has a through hole 412a in the longitudinal direction (left-right direction). Rubber bushing 412 has a female threaded portion 413b at its outer end portion that screws with the tip of bolt 413, which will be described later. Rubber bushing 412 has a deformation portion 412c in the center in the longitudinal direction (left-right direction).

[0096] The rubber bushing 412 is inserted into the mounting hole 243a of the mounting portion 243 of the inner wall portion 242. The rubber bushing 412 fixes the case portion 411 to the mounting portion 243 by screwing the tip portion of a bolt 413 inserted into the through hole 412a from either the left or right inner side of the rubber bushing 412 into the female thread portion 413b.

[0097] In this case, by tightening the bolt 413, the rubber bush 412 contracts in the left-right direction, and the deformed portion 411c is crushed and spreads outward. When the deformed portion 411c spreads outward, the rubber bush 412 is fixed to the mounting hole 243a. As a result, the case portion 411 is fixed to the mounting portion 243 of the inner wall portion 242 in the left-right direction.

[0098] Holding portion 414 is housed in case portion 411. Holding portion 414 holds movable portion 415, which will be described later, so as to be movable in the up and down direction.

[0099] As described above, the movable portion 415 is held by the holding portion 414 so as to be movable in the up and down direction. The movable portion 415 is limited by the holding portion 414 to only be movable in the up and down direction, and movement in the left and right direction is restricted.

[0100] The first adhesive member 416B is provided on the bottom surface of the movable part 415. The first adhesive member 416B is a plate-shaped gel mat made of a semi-solid gel material with adhesiveness. The first adhesive member 416B is fixed to the attachment part 243 of the inner wall part 242 by fixing the case part 411 to the attachment part 243 of the inner wall part 242. The bottom surface of the gel mat, which is the first adhesive member 416B, may be a flat surface or may be an uneven surface with, for example, a lattice-shaped groove formed therein.

[0101] The up-down direction adjustment part 417 is provided in the space between the holding part 414 and the movable part 415. The up-down direction adjustment part 417 moves the movable part 415 downward in the up-down direction. In other words, the up-down direction adjustment part 417 moves the first adhesive member 416B downward in the up-down direction.

[0102] The vertical direction adjustment part 417 is an elastic body that contracts in the vertical direction after the toilet body 2 is fixed to the floor surface FS compared to before the toilet body 2 is fixed to the floor surface FS. The vertical direction adjustment part 417 is, for example, a compression coil spring.

[0103] The second fixing portion 42B includes a base portion 421, a fixing screw 422, and a second adhesive member 423B. The base portion 421 is disposed at a predetermined position on the floor surface FS. The base portion 421 is a plate-shaped member.

[0104] The fixing screw 422 is screwed into the floor surface FS to fix the base part 421 to the floor surface FS.

[0105] The second adhesive member 423B is provided on the upper surface of the base portion 421. The second adhesive member 423B is a plate-shaped member to which the gel mat, which is the first adhesive member 416B, can be adhered. The second adhesive member 423B is preferably a plate-shaped member made of hard resin. The second adhesive member 423B may be, for example, a plate-shaped member made of metal.

[0106] In the flush toilet 1B pertaining to the third embodiment, when the toilet body 2 is placed on the floor surface FS, the fixed part 4B acts such that the vertical adjustment part 417 presses the first adhesive member 416B with a predetermined pressing force towards the second adhesive member 423B provided on the floor surface FS.

[0107] When the toilet body 2 is installed on the floor surface FS, the tolerance variation of the ceramic toilet body 2 is large, so the gap between the toilet body 2 and the floor surface FS is likely to become large, but according to the third embodiment described above, the vertical adjustment part 417 presses the first adhesive member 416B and the second adhesive member 423B together, thereby making it possible to reduce the gap between the toilet body 2 and the floor surface FS. In other words, the toilet body 2 can be installed on the floor surface FS while allowing for the tolerance variation specific to the ceramic toilet body 2. In addition, sewage does not seep into the installation surface of the toilet body 2 with the floor surface FS through the gap with the floor surface FS, improving cleanability and suppressing the generation of odors caused by sewage seeping into the toilet body 2.

[0108] Furthermore, according to the third embodiment as described above, there is no need to form holes in the toilet body 2 for fixing it to the floor surface FS, so sewage will not seep into the toilet body 2 through these holes, improving cleaning ease and suppressing the generation of odors caused by sewage seeingping into the toilet body 2.

[0109] Furthermore, if holes were formed in the toilet body 2, they would be visible to users and would look bad even if the holes were covered with stickers or decorative caps. However, according to the third embodiment described above, there are no holes in the toilet body 2, so the appearance is good and the design can be improved.

[0110] Furthermore, according to the third embodiment as described above, the vertical adjustment portion 417 is an elastic body that contracts in the vertical direction after the toilet body 2 and the floor surface FS are fixed, so that the vertical tolerance variation of the ceramic toilet body 2 can be more reliably tolerated with a simple configuration.

[0111] Furthermore, according to the third embodiment as described above, since the fixing portion 4B is fixed to the attachment portion 243 of the inner wall portion 242 by the rubber bushing 412 and the bolt 413, the fixing portion 4B can be easily fixed to the inner wall portion 242.

[0112] <Modification of the third embodiment> In the fixing portion 4B, the first fixing portion 41B may be composed of a first adhesive member 416B (gel mat), and the second fixing portion 42A may be composed of a second adhesive member 423B (a resin plate-shaped member). In such a modified example, the first adhesive member 416B and the second adhesive member 423B can be pressed against each other by utilizing the elastic force in the vertical direction (surface direction) of the gel mat generated by the load when the toilet body 2 is placed on the floor surface FS. In such a modified example, the first adhesive member 416B and the second adhesive member 423B themselves become the vertical direction adjustment portion 417.

[0113] As a result, similar to the third embodiment described above, the vertical adjustment part 417 presses the first adhesive member 416B and the second adhesive member 423B together, thereby making it possible to reduce the gap between the toilet body 2 and the floor surface FS. In other words, the toilet body 2 can be installed on the floor surface FS while allowing for the tolerance variations that are unique to the ceramic toilet body 2. Furthermore, sewage will not seep into the installation surface of the toilet body 2 with the floor surface FS through the gap with the floor surface FS, improving cleanability and suppressing the generation of odors caused by sewage seeping into the toilet body 2.

[0114] Furthermore, according to the above-described modified example, there is no need to form holes in the toilet body 2 for fixing it to the floor surface FS, so sewage will not seep into the toilet body 2 through these holes, improving cleaning ease and suppressing the generation of odors caused by sewage seeingping into the toilet body 2.

[0115] Furthermore, if holes are formed in the toilet body 2, they will be visible to users and will look bad even if the holes are hidden with stickers or decorative caps. However, according to the modified example described above, there are no holes in the toilet body 2, so the appearance is good and the design can be improved.

[0116] Further advantages and modifications may readily occur to those skilled in the art. Thus, the invention in its broader aspects is not limited to the specific details and representative embodiments shown and described above. Accordingly, various modifications may be made without departing from the spirit or scope of the general inventive concept as defined by the appended claims and equivalents thereof.
