Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the flushing toilet described in the above - mentioned Patent Document 1, since through holes are formed in the rear surface of the skirt portion of the toilet body, the flushing toilet cannot be installed with the rear end of the toilet body in contact with the wall surface. To solve this, it is conceivable to form through holes on the side surface of the skirt portion of the toilet body. However, if large through holes are formed on the side surface of the skirt portion of the toilet body, there is a problem that the overall appearance design of the toilet is impaired.

[0005] Therefore, the present invention has been made to solve the above-mentioned problems, and aims to provide a flush toilet that can improve the overall appearance and design of the toilet when a through hole is formed in the skirt portion of the toilet bowl body. [Means for solving the problem]

[0006] To solve the above-mentioned problems, the present invention provides a flush toilet that washes with flushing water and discharges waste, comprising: a toilet body comprising: a bowl portion for receiving waste; a drain trap pipe connected below the bowl portion for discharging waste; and a skirt portion covering the bowl portion and the drain trap pipe from the outside; a functional unit provided on the toilet body; and a connecting member for connecting a water supply or power supply source to the functional unit, wherein the skirt portion has a through hole through which the connecting member passes, and the through hole is provided with a first decorative cap having an opening smaller than the through hole.

[0007] According to the present invention configured in this way, a through-hole is formed in the skirt portion through which a connecting member passes, and a first decorative cap with a smaller opening than the through-hole is provided in the through-hole. Therefore, when installing a flush toilet, the first decorative cap can be removed from the through-hole to enlarge it, allowing relatively large connecting members such as power plugs to pass through. On the other hand, when using the flush toilet, the first decorative cap can be attached to the through-hole to enlarge it, allowing connecting members such as water supply hoses and power cords to pass through. As a result, the through-hole can be made smaller when using the flush toilet, making it less noticeable. Thus, when a through-hole is formed in the skirt portion of the toilet bowl, the overall appearance and design of the toilet bowl can be improved.

[0008] In the present invention, preferably, the first decorative cap is provided with a second decorative cap that covers the opening of the first decorative cap. In the present invention configured in this way, the first decorative cap is provided with a second decorative cap that covers the opening of the first decorative cap. Therefore, when the through hole in the skirt portion of the toilet bowl body is not used, the opening of the first decorative cap can be hidden by the second decorative cap, thereby improving the overall appearance and design of the toilet bowl.

[0009] Furthermore, the present invention preferably includes a fixing bolt provided on the first decorative cap and a locking member that is screwed onto the fixing bolt and contacts the back surface of the skirt portion.

[0010] In the present invention, preferably, the first decorative cap has a recess formed in a concave shape, and a fixing bolt is provided in this recess. In the present invention configured in this way, the first decorative cap has a recessed area, and a fixing bolt is provided within this recess. This makes the fixing bolt less conspicuous, thereby improving the overall appearance and design of the toilet bowl.

[0011] Furthermore, in the present invention, the fixing bolt is preferably located in the center of the first decorative cap. In the present invention configured in this way, the fixing bolt is positioned in the center of the first decorative cap, so that the first decorative cap can be stably fixed into the through hole.

[0012] In the present invention, preferably, the first decorative cap is provided with a rotation prevention part to prevent the locking member from rotating together with the fixing bolt. In the present invention configured as described above, the first decorative cap is provided with a rotation prevention part to prevent the locking member from rotating together with the fixing bolt, thereby preventing the locking member from rotating together with the fixing bolt and allowing the first decorative cap to be easily attached to the through hole.

[0013] Furthermore, in the present invention, the anti-rotation part is preferably located near the center of the first decorative cap. In the present invention configured in this way, the anti-rotation part is positioned near the center of the first decorative cap, so that when the first decorative cap is attached to the through hole, the anti-rotation part does not interfere with the through hole, and the first decorative cap can be easily attached to the through hole.

[0014] In the present invention, preferably, the fixing bolt is provided with a fall prevention member to prevent the locking member from falling off the fixing bolt. In the present invention configured as described above, the fixing bolt is provided with a fall prevention member to prevent the locking member from falling off the fixing bolt. Therefore, even if the fixing bolt is rotated excessively, the locking member will not fall off the fixing bolt, and the first decorative cap can be easily attached to the through hole.

[0015] Furthermore, in the present invention, preferably, the first decorative cap is provided with a second decorative cap that covers the opening of the first decorative cap, and this second decorative cap is configured to cover the opening and recess of the first decorative cap. In the present invention configured as described above, the first decorative cap is provided with a second decorative cap that covers the opening of the first decorative cap. Since the second decorative cap is configured to cover the opening and recess of the first decorative cap, the opening and recess of the first decorative cap can be hidden by the second decorative cap, thereby improving the overall appearance and design of the toilet bowl.

[0016] In the present invention, preferably, a rib portion that abuts against the surface of the skirt portion is provided on the outer peripheral edge of the first cosmetic cap. In the present invention configured as described above, since a rib portion that abuts against the surface of the skirt portion is provided on the outer peripheral edge of the first cosmetic cap, when a manufacturing error occurs in the toilet body, the gap between the first cosmetic cap and the surface of the skirt portion can be made inconspicuous, and the appearance design of the entire toilet can be improved.

[0017] Also, in the present invention, preferably, the through-hole of the skirt portion is disposed on the rear side of the center in the front-rear direction of the toilet body and on the lower side of the center in the vertical direction of the toilet body.

Mode for Carrying Out the Invention

[0020] Hereinafter, with reference to the drawings, the flush toilet according to an embodiment of the present invention will be described. First, the overall structure of the flush toilet according to this embodiment will be described with reference to Figures 1 and 2. Figure 1 is a perspective view of the flush toilet according to an embodiment of the present invention, and Figure 2 is a left-side cross-sectional view of the flush toilet according to an embodiment of the present invention. In this specification, when a user is viewing a flush toilet from the front, the front side of the flush toilet is referred to as "front," the back side as "rear," the right side as "right," and the left side as "left."

[0021] As shown in Figure 1, the flush toilet 1 comprises a ceramic toilet bowl 2, a local cleaning device 4 positioned on the upper surface of the toilet bowl 2, and a flush water tank 6 for storing flush water to be supplied to the toilet bowl 2. The flush toilet 1 of this embodiment is a floor-standing flush toilet installed on the floor surface FL with the rear ends of the toilet bowl 2 and the flush water tank 6 in contact with (or close to) the wall surface W. Furthermore, the flush toilet 1 of this embodiment is configured so that flush water stored in the flush water tank 6 is supplied to the toilet bowl 2 by operating a button 6a provided on the upper surface of the flush water tank 6. In addition, the flush toilet 1 of this embodiment is a wash-down type toilet that washes away waste by the flowing action caused by the drop in the flush water.

[0022] As shown in Figure 2, the toilet body 2 comprises a bowl-shaped bowl section 8, a drain trap pipe 10 connected below the bowl section 8 for discharging waste, and a skirt section 12 that covers the bowl section 8 and the drain trap pipe 10 from the outside. The drain trap pipe 10 comprises an inlet 10a, an introduction pipe 10b descending from the inlet 10a, an ascending pipe 10c rising from the downstream end of the introduction pipe 10b, a horizontal pipe 10d extending rearward from the downstream end of the ascending pipe 10c, and a top section 10e located between the ascending pipe 10c and the horizontal pipe 10d. A drain socket (not shown) is attached to the downstream end of the horizontal pipe 10d of the drain trap pipe 10 and is connected to a drain pipe (not shown) provided on the floor surface FL.

[0023] The bowl section 8 comprises a waste receiving surface 14 for receiving waste, a rim section 16 formed above the waste receiving surface 14, a shelf surface 18 formed between the waste receiving surface 14 and the rim section 16, and a pot section 20 formed below the waste receiving surface 14, in which water is collected. The rim section 16 is provided with a first rim outlet 22 for discharging cleaning water toward the front of the bowl section 8 and a second rim outlet (not shown) for discharging cleaning water toward the rear of the bowl section 8. The first rim outlet 22 is located on the left rear side of the bowl section 8, and the second rim outlet is located on the right rear side of the bowl section 8. The cleaning water discharged from the first rim outlet 22 and the second rim outlet flows down the shelf surface 18, forming a swirling flow that swirls in the same direction, and cleans the waste receiving surface 14.

[0024] Inside the rear of the toilet bowl body 2, there is a common water channel 24 that connects to the drain port 6b of the flushing water tank 6, a first rim water channel (not shown) that branches off from the downstream end of the common water channel 24 and connects to the first rim outlet 22, and a second rim water channel (not shown) that branches off from the downstream end of the common water channel 24 and connects to the second rim outlet.

[0025] The skirt portion 12 comprises a front wall portion 12a provided on the front of the toilet bowl body 2, side wall portions 12b provided on the left and right sides of the toilet bowl body 2, and a rear wall portion 12c provided on the back of the toilet bowl body. The front wall portion 12a, side wall portions 12b, and rear wall portion 12c of the skirt portion 12 are formed continuously and surround the bowl portion 8 and the drain trap pipe 10. Thus, the skirt portion 12 constitutes the external shape of the toilet bowl body 2.

[0026] As shown in Figure 2, the local washing device 4 comprises a main body 4a, a washing nozzle (not shown) that is movable forward and backward from the main body 4a, a toilet seat 4b that is rotatably attached to the main body 4a, and a toilet lid 4c that is rotatably attached to the main body 4a so as to cover the toilet seat 4b. The local washing device 4 is an example of a "functional part" in the present invention.

[0027] As shown in Figure 2, the flushing water tank 6 is mounted on the rear upper surface of the toilet bowl body 2. Inside the flushing water tank 6, there is a drain valve device 6c that opens and closes the drain port 6b in response to the operation of a button 6a. The flushing water tank 6 is configured so that the flushing water in the flushing water tank 6 can be supplied to or stopped from flowing to the toilet bowl body 2 by the opening and closing of the drain port 6b by the drain valve device 6c. Inside the flushing water tank 6, there is a water supply valve device (not shown) for supplying flushing water to the flushing water tank 6. Note that the flushing water tank 6 is an example of a "functional part" in the present invention.

[0028] A water supply hose 26 is connected to the water supply valve device via a branch valve (not shown), and cleaning water from the water pipe, which is the water supply source, is supplied to the cleaning water tank 6 via the water supply hose 26 and the water supply valve device. In addition, a water supply hose for WL (not shown) that connects to the local cleaning device 4 is connected to the branch valve, and cleaning water from the water pipe is supplied to the local cleaning device 4 via the water supply hose 26 and the water supply hose for WL.

[0029] The water supply hose 26 is a flexible hose, with one end connected to a water supply valve device in the flushing water tank 6 and the other end connected to a shut-off valve 28. The water supply hose 26 is an example of a "connecting member" in the present invention. The shut-off valve 28 is installed on the left wall W of the flush toilet 1 and extends horizontally from the wall W. In this embodiment, the shut-off valve 28 is installed on the left wall W of the flush toilet 1, but it may also be installed on the right wall W of the flush toilet 1. Also, in this embodiment, the shut-off valve 28 is installed on the wall W, but it may also be installed on the floor FL.

[0030] Next, with reference to Figures 2 to 5, the through-hole 30 provided in the skirt portion 12 of the flush toilet 1 according to this embodiment will be described. Figure 3 is a rear view of a flush toilet according to an embodiment of the present invention, and Figures 4 and 5 are enlarged perspective views of the left rear portion of the skirt portion of the toilet bowl body of the flush toilet according to an embodiment of the present invention, with Figure 4 showing the state in which a through hole is used and Figure 5 showing the state in which a through hole is not used.

[0031] As shown in Figures 2 and 3, through-holes 30 are formed in the side wall portion 12b of the skirt portion 12, through which connecting members such as the water supply hose 26, power cord, and power plug pass. The through-holes 30 are formed as perfect circles with an inner diameter of approximately 50 mm, and are sized to allow a relatively large power plug to pass through. The power plug is a power plug provided on the power cord that connects to the local flushing device 4, and is connected to an outlet, which is the power source for supplying electricity. The through-holes 30 are located behind the center of the toilet body 2 in the front-to-back direction, and below the center of the toilet body 2 in the vertical direction. The through-holes 30 are formed in the left and right side wall portions 12b, respectively. Either one of the through-holes 30 is used depending on the position of the shut-off valve 28 (left or right side of the flush toilet 1). Each through-hole 30 is formed with the same opening area and shape, and is positioned symmetrically with respect to the center of the toilet body 2 in the left-to-right direction.

[0032] As shown in Figure 4, when the through-hole 30 is used, the second decorative cap 36 is removed while the first decorative cap 34 of the decorative cap member 32 (details to be described later) is attached. As a result, the through-hole 30 becomes open, and the water supply hose 26 passes through the through-hole 30. On the other hand, as shown in Figure 5, when the through-hole 30 is not used, the first decorative cap 34 and the second decorative cap 36 of the decorative cap member 32 are attached, and the through-hole 30 is closed. As shown in Figure 3, in this embodiment, the left through-hole 30 is used and in an open state (as shown in Figure 4), and the right through-hole 30 is not used and is closed (as shown in Figure 5).

[0033] As shown in Figures 2 and 3, the water supply hose 26 connected to the shut-off valve 28 is drawn into the toilet bowl body 2 through the through hole 30 and extends upward to the right within the toilet bowl body 2. After extending within the toilet bowl body 2, the water supply hose 26 is pulled out through the upper opening 2a formed on the upper surface of the toilet bowl body 2. After being pulled out through the upper opening 2a, the water supply hose 26 extends upward within the rear recess 6e formed in the rear wall surface 6d of the flushing water tank 6. After extending upward within the rear recess 6e, the water supply hose 26 is drawn into the flushing water tank 6 through the rear opening 6f formed at the upper end of the rear recess 6e. The water supply hose 26 is connected to the water supply valve device within the flushing water tank 6.

[0034] Next, with reference to Figures 6 to 9, the decorative cap member 32 of the flush toilet 1 according to this embodiment will be described. Figure 6 is an exploded perspective view of a decorative cap member for a flush toilet according to an embodiment of the present invention; Figure 7 is a front view of the decorative cap member for a flush toilet according to an embodiment of the present invention installed in a through hole; Figure 8 is a rear view of the decorative cap member for a flush toilet according to an embodiment of the present invention installed in a through hole; and Figure 9 is a cross-sectional view taken along the line IX-IX in Figure 7.

[0035] As shown in Figure 6, the decorative cap member 32 is a member for covering the through hole 30 of the skirt portion 12, and comprises a first decorative cap 34, a second decorative cap 36, a fixing bolt 38, a locking member 40, and a nut 42.

[0036] The first decorative cap 34 is a resin panel that is sized to cover the through-hole 30 from the outside and is formed in a perfectly circular shape. When the first decorative cap 34 is removed from the through-hole 30 during the installation of the flush toilet 1, the through-hole 30 opens wide (fully open), allowing not only the water supply hose 26 and power cord but also a relatively large power plug to pass through the through-hole 30.

[0037] As shown in Figures 7 and 9, the surface (front) of the first decorative cap 34 has a recessed area 34a formed near its center when viewed from the front. The recessed area 34a is formed to be more recessed than other areas of the first decorative cap 34. The recessed area 34a is formed to be larger than the diameter of the head 38a of the fixing bolt 38 and deeper than the height of the head 38a of the fixing bolt 38. This allows the head 38a of the fixing bolt 38 to be accommodated within the recessed area 34a. The width of the recessed area 34a is set to be the same as the width of the opening 34c, and the recessed area 34a is positioned adjacent to the opening 34c (see Figure 7).

[0038] The first decorative cap 34 has a bolt hole 34b formed in its center when viewed from the front, through which a fixing bolt 38 passes. The bolt hole 34b is formed within the recess 34a. The inner diameter of the bolt hole 34b is smaller than the head diameter of the head 38a of the fixing bolt 38, and larger than the thread diameter of the male threaded portion 38b of the fixing bolt 38.

[0039] Furthermore, the first decorative cap 34 has an opening 34c, which is a notch, formed in a front view below the bolt hole 34b. The opening 34c is smaller than the through hole 30 and larger than the outer diameter of the water supply hose 26. When the second decorative cap 36 is removed while the first decorative cap 34 is attached, the through hole 30 is opened to a smaller size, allowing the water supply hose 26 and power cord to pass through the opening 34c and through hole 30 of the first decorative cap 34. In this embodiment, the opening 34c is formed by a notch, but it may also be formed by a hole.

[0040] As shown in Figure 6, the back surface (rear) of the first decorative cap 34 has a projection 34d (anti-rotation part) that extends horizontally toward the back side (rear side). When viewed from the rear, this projection 34d is located near the center of the first decorative cap 34 (near the bolt hole 34b), below the bolt hole 34b and above the opening 34c (see Figure 8). Two projections 34d are provided, and each projection 34d is located on either side of the bolt hole 34b, sandwiching the bolt hole 34b. As a result, when the fixing bolt 38 rotates, the locking member 40 comes into contact with one of the projections 34d, preventing the locking member 40 from rotating together with the fixing bolt 38.

[0041] Furthermore, as shown in Figure 6, an engaging receiving portion 34e is formed on the back surface of the first decorative cap 34, into which the engaging claw portion 36a of the second decorative cap 36 engages. The engaging receiving portion 34e is formed in a concave shape so that the engaging claw portion 36a engages. Two engaging receiving portions 34e are provided on the edge of the opening 34c.

[0042] As shown in Figures 6 and 9, a rib portion 34f is formed on the back surface of the first decorative cap 34, which abuts against the surface of the skirt portion 12. The rib portion 34f extends horizontally from the outer peripheral edge of the first decorative cap 34 toward the back side. The rib portion 34f is provided around the entire circumference of the outer peripheral edge of the first decorative cap 34. By having the rib portion 34f of the first decorative cap 34 abut against the surface of the skirt portion 12, even if there is a manufacturing error in the toilet bowl body 2, the gap between the first decorative cap 34 and the surface of the skirt portion 12 will not be noticeable.

[0043] The second decorative cap 36 is a resin plate and is sized to cover the opening 34c and recess 34a of the first decorative cap 34, and is formed in an elongated shape. The second decorative cap 36 is removed from the first decorative cap 34 when the through hole 30 is used (see Figure 4), and is attached to the first decorative cap 34 when the through hole 30 is not used (see Figure 5). When the second decorative cap 36 is removed from the first decorative cap 34, the water supply hose 26 and power cord can be passed through the opening 34c and through hole 30 of the first decorative cap 34.

[0044] As shown in Figure 6, the back surface of the second decorative cap 36 has an engaging claw portion 36a that extends horizontally toward the back side. The engaging claw portion 36a is configured to deform elastically and engage with the engaging receiving portion 34e. This allows the second decorative cap 36 to be detachably attached to the first decorative cap 34. Two engaging claw portions 36a are provided on the outer edge of the second decorative cap 36.

[0045] As shown in Figures 6 and 9, the fixing bolt 38 is a metal bolt comprising a head 38a and a male threaded portion 38b extending from the head 38a with a male thread formed thereon. The fixing bolt 38 is inserted into the bolt hole 34b from the outside (surface side) of the first decorative cap 34. The fixing bolt 38 is positioned in the center of the first decorative cap 34 and extends through the through hole 30. The head 38a of the fixing bolt 38 is housed in a recess 34a of the first decorative cap 34 so as not to be conspicuous.

[0046] As shown in Figures 6, 8, and 9, the locking member 40 is a long, slender metal plate and has a female threaded portion 40a with an internal thread formed thereon. The female threaded portion 40a is positioned in the axial center of the locking member 40 and is configured to be screwed into by the male threaded portion 38b of the fixing bolt 38. The axial length of the locking member 40 is set to be longer than the inner diameter of the through hole 30. When the fixing bolt 38 is rotated, the locking member 40 moves in the axial direction of the fixing bolt 38 and comes into contact with the back surface of the skirt portion 12. Also, when the fixing bolt 38 is rotated, the locking member 40 comes into contact with the projection 34d and does not rotate together with the fixing bolt 38.

[0047] The nut 42 (fall prevention member) is a nut with a female thread formed on it, and is screwed onto the fixing bolt 38 and provided on the tip of the fixing bolt 38. By providing the nut 42 on the fixing bolt 38, if the fixing bolt 38 is rotated excessively, the movement of the locking member 40 is stopped, preventing the locking member 40 from falling off the fixing bolt 38.

[0048] Next, with reference to Figures 10A to 10D, a method for attaching the decorative cap member 32 of the flush toilet 1 according to an embodiment of the present invention to the through hole 30 will be described. Figures 10A to 10D illustrate a method for attaching a decorative cap member to a through-hole of a flush toilet according to an embodiment of the present invention. Figure 10A shows the state before attaching the decorative cap member to the through-hole, Figure 10B shows the state during attachment with the decorative cap member inserted into the through-hole, Figure 10C shows the state during attachment after the decorative cap member has been inserted into the through-hole, and Figure 10D shows the state after the decorative cap member has been attached to the through-hole.

[0049] First, as shown in Figure 10A, before the decorative cap member 32 is attached to the through-hole 30 of the skirt portion 12, the through-hole 30 is wide open (fully open). This allows, for example, when installing the flush toilet 1, not only the water supply hose 26 and power cord but also a relatively large power plug to be passed through the through-hole 30.

[0050] The decorative cap member 32 is installed in the through hole 30 with each component pre-assembled. Specifically, a fixing bolt 38 is inserted into the bolt hole 34b of the first decorative cap 34. A locking member 40 and a nut 42 are screwed onto the fixing bolt 38. The locking member 40 is located at a predetermined distance L1 from the first decorative cap 34, and the nut 42 is located at the tip of the fixing bolt 38.

[0051] Next, as shown in Figure 10B, the decorative cap member 32 is inserted into the through hole 30 at an angle of approximately 45 degrees relative to the skirt portion 12. Since the distance between the first decorative cap 34 and the locking member 40 is a predetermined distance L1, the edge of the through hole 30 fits between the first decorative cap 34 and the locking member 40, allowing the locking member 40 to be inserted into the through hole 30.

[0052] Furthermore, as shown in Figure 10C, after the locking member 40 is inserted into the through hole 30, the decorative cap member 32 is moved so that the center of the first decorative cap 34 coincides with the center of the through hole 30.

[0053] Next, as shown in Figure 10D, with the first decorative cap 34 fitted into the through hole 30, the fixing bolt 38 is rotated. As the fixing bolt 38 is rotated, the locking member 40 moves along the fixing bolt 38 in a direction toward the back surface of the skirt portion 12. As the fixing bolt 38 is rotated further, the distance between the first decorative cap 34 and the locking member 40 decreases from a predetermined distance L1 to a predetermined distance L2, causing the locking member 40 to come into contact with the back surface of the skirt portion 12, and the rib portion 34f of the first decorative cap 34 to come into contact with the surface of the skirt portion 12. As a result, the decorative cap member 32 is fixed into the through hole 30 of the skirt portion 12.

[0054] To remove the decorative cap member 32, the fixing bolt 38 is rotated in the reverse direction. When the fixing bolt 38 is rotated in the reverse direction, the locking member 40 moves along the fixing bolt 38 in a direction away from the back surface of the skirt portion 12. Since a nut 42 is provided at the tip of the fixing bolt 38, the locking member 40 will not fall off the fixing bolt 38 even if the fixing bolt 38 is rotated excessively. To prevent the nut 42 itself from falling off, it is possible to more reliably prevent the locking member 40 from falling off the fixing bolt 38 by applying adhesive between the nut 42 and the fixing bolt 38, or by using a nylon nut in which a nylon ring is built into the nut and the frictional force between the ring and the fixing bolt 38 prevents the nut 42 from loosening.

[0055] After the decorative cap member 32 is attached to the through hole 30 of the skirt portion 12, the through hole 30 is left slightly open (less than half the opening of the fully open state) when the first decorative cap 34 is attached and the second decorative cap 36 is removed. This makes it possible to make the through hole 30 the minimum size necessary for the water supply hose 26 and power cord to pass through when using the flush toilet 1, for example, and makes the through hole 30 less noticeable.

[0056] Next, the effects and advantages of the flush toilet 1 according to this embodiment described above will be explained. First, in the flush toilet 1 according to this embodiment, a through-hole 30 is formed in the skirt portion 12 through which a connecting member (such as a water supply hose, power cord, or power plug) passes, and a first decorative cap 34 is provided in the through-hole 30 with an opening 34c smaller than the through-hole 30. Therefore, when installing the flush toilet 1, the first decorative cap 34 can be removed from the through-hole 30 to enlarge the through-hole 30, allowing a relatively large connecting member such as a power plug to pass through. On the other hand, when using the flush toilet 1, the first decorative cap 34 can be attached to the through-hole 30 to enlarge the through-hole 30, allowing a connecting member such as a water supply hose or power cord to pass through. As a result, the through-hole 30 can be made smaller when using the flush toilet 1, making the through-hole 30 less noticeable. Thus, when a through-hole 30 is formed in the skirt portion 12 of the toilet body 2, the overall appearance and design of the toilet can be improved.

[0057] In the flush toilet 1 according to this embodiment, the first decorative cap 34 is provided with a second decorative cap 36 that covers the opening 34c of the first decorative cap 34. Therefore, when the through hole 30 of the skirt portion 12 of the toilet body 2 is not used, the opening 34c of the first decorative cap 34 can be hidden by the second decorative cap 36, thereby improving the overall appearance and design of the toilet.

[0058] Furthermore, in the flush toilet bowl 1 according to this embodiment, a fixing bolt 38 is provided on the first decorative cap 34, and a locking member 40 is screwed onto the fixing bolt 38 and comes into contact with the back surface of the skirt portion 12. Therefore, by rotating the fixing bolt 38 and bringing the locking member 40 into contact with the back surface of the skirt portion 12, the first decorative cap 34 can be easily attached to the through hole 30.

[0059] In the flush toilet bowl 1 according to this embodiment, the first decorative cap 34 has a recessed area 34a, and a fixing bolt 38 is provided in this recessed area 34a. This makes the fixing bolt 38 less conspicuous, thereby improving the overall appearance and design of the toilet bowl.

[0060] Furthermore, in the flush toilet bowl 1 according to this embodiment, the fixing bolt 38 is positioned in the center of the first decorative cap 34, so that the first decorative cap 34 can be stably fixed to the through hole 30.

[0061] In the flush toilet bowl 1 according to this embodiment, the first decorative cap 34 is provided with a projection 34d (anti-rotation part) to prevent the locking member 40 from rotating together with the fixing bolt 38. This prevents the locking member 40 from rotating together with the fixing bolt 38, allowing the first decorative cap 34 to be easily attached to the through hole 30.

[0062] Furthermore, in the flush toilet bowl 1 according to this embodiment, the projection 34d (anti-rotation part) is positioned near the center of the first decorative cap 34. This prevents the projection 34d from interfering with the through hole 30 when attaching the first decorative cap 34 to the through hole 30, allowing the first decorative cap 34 to be easily attached to the through hole 30.

[0063] In the flush toilet bowl 1 according to this embodiment, the fixing bolt 38 is provided with a nut 42 (fall prevention member) to prevent the locking member 40 from falling off the fixing bolt 38. Therefore, even if the fixing bolt 38 is rotated excessively, the locking member 40 is prevented from falling off the fixing bolt 38, and the first decorative cap 34 can be easily attached to the through hole 30.

[0064] Furthermore, in the flush toilet bowl 1 according to this embodiment, the first decorative cap 34 is provided with a second decorative cap 36 that covers the opening 34c of the first decorative cap 34. Since the second decorative cap 36 is configured to cover the opening 34c and recess 34a of the first decorative cap 34, the opening 34c and recess 34a of the first decorative cap 34 can be hidden by the second decorative cap 36, thereby improving the overall appearance and design of the toilet bowl.

[0065] In the flush toilet bowl 1 according to this embodiment, the outer edge of the first decorative cap 34 is provided with a rib portion 34f that contacts the surface of the skirt portion 12. Therefore, if a manufacturing error occurs in the toilet bowl body 2, the gap between the first decorative cap 34 and the surface of the skirt portion 12 can be made less noticeable, thereby improving the overall appearance and design of the toilet bowl.

[0066] Furthermore, in the flush toilet bowl 1 according to this embodiment, the through-hole 30 of the skirt portion 12 is located behind the center in the front-to-back direction of the toilet bowl body 2, and below the center in the vertical direction of the toilet bowl body 2. This makes the through-hole 30 less conspicuous, thereby improving the overall appearance and design of the toilet bowl.

[0067] In this embodiment of the flush toilet, the "functional part" of the present invention is shown as a flushing water tank and a local cleaning device. However, the "functional part" of the present invention is not limited to this, and may be, for example, a pressure pump, a pressure accumulator, a toilet bowl flushing device, or a functional water generating device. Also, in this embodiment of the flush toilet, the "connecting member" of the present invention is shown as a water supply hose. However, the "connecting member" of the present invention is not limited to this, and may be, for example, a power cord or a power plug.

[0068] The present invention is not limited to the embodiments described above, and various modifications and variations are possible within the scope of the technical idea described in the claims. [Explanation of Symbols]
