Description

[Technical Field]

[0001] The present invention relates to a waterproof pan for installing, for example, a washing machine. [Background technology]

[0002] BACKGROUND ART Conventionally, a waterproof pan is installed on the floor of a washroom, a dressing room, or the like, and a washing machine is installed on the waterproof pan.

[0003] Water can be supplied to the washing machine by pulling a water supply pipe from under the floor to above the floor and connecting it to a water supply tap provided in the waterproof pan, and then connecting a water supply hose for the washing machine to the water supply tap. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Utility Model Registration No. 3230848 Summary of the Invention [Problem to be solved by the invention]

[0005] The water supply valve provided in the waterproof pan is provided so as to protrude upward from the floor panel of the waterproof pan. Because the water supply valve is exposed, it looks unsightly and there is room for improvement.

[0006] In view of the above-mentioned circumstances, the present invention aims to solve the problem by providing a waterproof pan that looks good. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the waterproof pan of the present invention comprises a pan body having a bottom that is placed on the floor surface, a rectangular base that extends in the front-to-back and left-to-right directions, and a mounting base that is placed at the four corners of the base, a water supply tap that protrudes vertically from the base, and a cover that covers the water supply tap.

[0008] According to the present invention, by covering the water faucet that projects in the height direction from the base with a cover, the water faucet is not exposed, and the appearance is improved.

[0009] Furthermore, in the waterproof pan of the present invention, a handle for opening and closing the water faucet may protrude outward from the outer surface of the cover.

[0010] As described above, if the handle for opening and closing the water tap protrudes outward from the outer surface of the cover, the water tap can be opened and closed quickly by operating the handle protruding outward from the outer surface of the cover without removing the cover.

[0011] Furthermore, the waterproof pan of the present invention may have a drain outlet formed in the base, and the drain outlet, the water supply tap, and the cover may be lined up in the left-right direction between the adjacent mounting stands in the left-right direction.

[0012] As described above, if the drain outlet, water supply tap, and cover are lined up in the left-right direction between adjacent mounting tables in the left-right direction, the work of connecting the drain hose to the drain outlet and the work of connecting the water supply hose to the water supply tap can be carried out quickly.

[0013] Furthermore, the waterproof pan of the present invention may be capable of being stored sideways with a water supply hose for connecting to the water supply port of the water tap wound around the center of the pan body.

[0014] As described above, if the water supply hose is stored horizontally in a rolled state in the center of the pan body, there is no need for a storage container or anti-interference material, compared to, for example, removing the water supply hose stored in a container and connecting it to the water supply inlet of the water faucet, which reduces waste at the construction site and allows the water supply hose to be immediately grasped and quickly connected to the water supply inlet of the water faucet. [Effects of the Invention]

[0015] According to the present invention, by providing a cover that covers the water supply tap, a waterproof pan that looks good can be provided. [Brief explanation of the drawings]

[0017] In FIG. 1, a waterproof pan 5 is disposed in a space 4 formed by three wall surfaces 1, 2, and 3 and having an open front side. In the following description, the near side in the depth direction of the waterproof pan 5 when viewed from the direction of arrow Y in FIG. 1 is referred to as the front side, the far side in the depth direction is referred to as the rear side, and the direction perpendicular to the depth direction is referred to as the left-right direction. In this embodiment, a waterproof pan 5 for installing a washing machine (not shown) will be described. The view from the direction of arrow Y in FIG. 1 is referred to as the front view. In this embodiment, the waterproof pan 5 is disposed in the space 4 formed by the three wall surfaces 1, 2, and 3, but the waterproof pan 5 may be disposed so that one side is aligned with one wall surface, or so that two sides are aligned with two wall surfaces.

[0018] The waterproof pan 5 is rectangular (it is square in FIG. 1 , but it can also be rectangular) and includes a pan body 6, a water tap 7, and a cover 8 that covers the water tap 7. If the water tap 7 is exposed, it looks unsightly, and moisture and dust can accumulate, creating an uneven outer shape, making cleaning difficult and posing a risk of finger injury. Leaving moisture and dust behind can lead to adhesion, leading to corrosion and discoloration of the metal parts, which can lead to poor aesthetics and make maintenance difficult. To address these issues, the present invention covers the water tap 7 with a cover 8. This improves the maintainability of the water tap 72 and the pan body 6, and the cover 8 prevents detergent from adhering to the water tap 72 and corrosion of the metal parts due to the laundry wastewater backflow prevention structure, thereby improving maintenance performance.

[0019] As shown in FIGS. 1 to 3, the pan body 6 has a bottom 61 having an upper surface 61A and a number of reinforcing ribs R (see FIG. 6) protruding downward from the underside, and sidewalls 62 protruding in the height direction (vertical direction) from the outer periphery of the bottom 61. The pan body 63 extends in the front-to-rear and left-to-right directions, and mounting tables 64 are disposed at the four corners of the base 63. Since the mounting tables 64 are disposed at the four corners of the base 63, the sidewalls 62 are provided at four locations in the circumferential direction so as to connect adjacent mounting tables 64, 64 in the circumferential direction. An outer corner 64K of the four corners of each mounting table 64 is formed with a through-hole 64A through which a wood screw (not shown) can be inserted to secure the waterproof pan 5 to the floor 9 (see FIGS. 2 and 3). The bottom 61 is provided with numerous ribs R (see Figure 6), so that the underside of the bottom 61 does not come into contact with the upper surface of the floor 9, but the numerous ribs R come into contact with the upper surface of the floor 9 and support the waterproof pan 5. Each of the four side wall portions of each mounting base 64 is inclined so that the higher it goes, the more inward it is positioned.

[0020] The bottom 61 is formed with a circular drain outlet 61B to which a drain hose (not shown) connected to the washing machine is connected, and a circular through-hole 61C for attaching the water supply tap 7. As shown in FIGS. 1 and 4, the drain outlet 61B and the through-hole 61C are aligned in the left-right direction between the left and right front-side mounting bases 64, 64. Because the drain outlet 61B has a larger diameter than the through-hole 61C, the center of the drain outlet 61B is located rearward of the center of the through-hole 61C and forward of the rear wall portion 64b of the right-side mounting base 64 in the front-rear direction. In this embodiment, the through-hole 61C is formed larger than the through-hole 9A in the floor 9 (described later) (see FIG. 6). The top surface 61A of the pan body 6 is formed as a sloped surface positioned slightly downward toward the drain outlet 61B so that leaking water moves toward the drain outlet 61B.

[0021] Furthermore, the pan body 6 is formed from synthetic resin (or metal), and the base 63 and the four mounting tables 64 are integrally formed, but the base 63 and the four mounting tables 64 may be formed separately and then integrated by fitting or engaging the base 63 and the four mounting tables 64 together.

[0022] 6 and 7, the water faucet 7 includes a joint 71 connected to a water supply pipe 10 disposed under the floor, a water faucet part 72 connected to the downstream end of the joint 71, and a water supply port part 73 connected to the downstream end (the upper end in FIG. 6) of the water faucet part 72. The water faucet 7 is disposed in the front region of the base body 63 in the fore-and-aft direction.

[0023] 6, the joint part 71 includes a joint body 71A to which the water supply pipe 10 is connected, a cylindrical outer cylinder 71B that covers the outer surface of the lower part of the joint body 71A, and a flange 71C for fixing the joint body 71A to the upper surface of the floor 9. A through hole 9A is formed in the floor 9 to allow the joint part 71 of the water supply tap 7 to pass through.

[0024] The water supply pipe 10 is sandwiched between the inner O-ring 11 provided on the joint body 71A and the outer O-ring 12, thereby sealing the space between the inside of the water supply pipe 10 and the outside of the joint body 71A.

[0025] The flange 71C includes a cylindrical portion 71D that is fitted onto the upper portion of the joint body 71A, and a ring-shaped flange portion 71E that extends outward from the lower end of the cylindrical portion 71D.

[0026] The cylindrical portion 71D includes a first cylindrical portion 71a that is detachably fixed to the upper part of the joint body 71A by screwing, a second cylindrical portion 71b that has a larger diameter than the first cylindrical portion 71a, and a horizontal ring-shaped connecting portion 71c that connects the lower end of the first cylindrical portion 71a to the upper end of the second cylindrical portion 71b. An O-ring 71F provided on the joint body 71A seals the gap between the inner surface of the first cylindrical portion 71a and the outer surface of the joint body 71A.

[0027] As shown in FIG. 7, a plurality of through-holes 71G are formed around the circumference of flange 71E at multiple locations for receiving screws 13 to secure flange 71E to floor 9. Each through-hole 71G has an axial cross section that is approximately trapezoidal and conical (mortar-shaped). A ring-shaped seal member 14 is provided between the underside 6B of the pan body 6 where the water faucet 7 is attached and the upper surface 71e of flange 71E. The seal member 14 is made of a foamed resin, such as sponge (or may be soft resin or rubber (including natural rubber or synthetic rubber)). The seal member 14 is provided to prevent water from moving downward through gap 15 (see FIG. 6) between the through-hole 61C for attaching the water faucet formed in pan body 6 and the outer surface of the second cylindrical portion 71b of flange 71C of the water faucet 7 and leaking onto or below the floor. Furthermore, the sealing member 14 is disposed on the screw 13, and prevents water leaking between the head 13A of the screw 13 (see FIG. 7) and the through-hole 71G from leaking under the floor. The screw 13 is a cross-recessed flat head tapping screw, and when the screw 13 is tightened until it contacts the through-hole 71G of the flange 71E, it becomes substantially flush with the upper surface 71e of the flange 71E, improving the sealing performance of the sealing member 14. "Substantially flush" includes cases where the upper surface of the head 13A of the screw 13 protrudes slightly from the upper surface 71e of the flange 71E, or where the upper surface of the head 13A of the screw 13 is positioned slightly below the upper surface 71e of the flange 71E.

[0028] The gap 15 occurs between the through hole 61C and the outer surface of the second tubular portion 71b of the flange 71C of the water faucet 7 because the through hole 61C is made 5 mm or more larger than the outer diameter of the water faucet 7. This is because the water faucet 7 is first fixed to the floor 9 with a plurality of screws 13, and then the waterproof pan 5 is attached, and there are cases where it is desired to slightly shift (change) the position of the waterproof pan 5 in the horizontal direction in relation to the horizontal position of the waterproof pan 5 and the position of the drain outlet 61B, and so the through hole 61C is made 5 mm or more larger than the outer diameter of the water faucet 7.

[0029] The reason water flows into through-hole 61C is thought to be that the sealing O-ring attached to faucet 7 leaks as water moves through faucet 7 due to aging or a defective product. For example, water leaks from O-ring 16A (see FIG. 6) provided between operating shaft 72b, which rotates integrally with handle 72B (described below), and support portion 27, which supports the rotation of operating shaft 72b, or from O-ring 16 (see FIG. 7) provided at the connection between faucet portion 72 and water inlet port 73, causing water to leak into through-hole 61C. The arrows in FIG. 7 indicate the state of water leakage.

[0030] As shown in Figure 4, when the waterproof pan 5 in Figure 1 is viewed from the front, an enclosure wall 19 is provided between the inner wall 64a of one (the right) of the two mounting stands 64, 64 located at the front and adjacent to each other in the left-right direction, and the side wall 62 connecting the left and right mounting stands 64, 64, and having a first wall portion 17 extending in the left-right direction and a second wall portion 18 extending in the front-to-back direction that surrounds the lower part of the water faucet 7. By providing the enclosure wall 19 in this way, a storage space 20 for storing the water faucet 7 is formed, and the enclosure wall 19 also functions as a vertical wall for preventing wastewater that has flowed back from the drain outlet 61B from immediately flowing into the through-hole 61C. Even if the drainage water flowing back from the drain outlet 61B accumulates in the pan body 6, the height from the bottom 61 of the pan body 6 to the bottom of the cutout 17K formed in the first wall portion 17 is set to 10 mm or more, so if the water level of the drainage water is less than 10 mm, it will not flow into the storage space 20 that stores the water tap 7.

[0031] The surrounding wall 19 also functions as a storage section for storing water that leaks from the water tap 7. When the level of the stored water exceeds the bottom of a cutout 17K (see Figures 4 and 6) formed in the first wall section 17, which will be described later, the stored water flows into the pan body 6 and is guided to the drain outlet 61B. The height from the bottom 61 of the pan body 6 to the bottom of the cutout 17K is set lower than the height from the bottom 61 of the pan body 6 to the upper surface of the side wall section 62, so water whose level exceeds the bottom of the cutout 17K does not flow out of the pan body 6.

[0032] Of the side wall portions 62 connecting the mounting bases 64, 64, the side wall portion 62 that forms the storage space 20 is set to have a smaller dimension (width dimension) in the inward and outward directions than the other side wall portions 62. This allows the water faucet 7 to be positioned closer to the front end.

[0033] The bottom 61 of the portion forming the storage space 20 is composed of multiple (two in FIG. 4) stepped bottom portions 61a, 61b to improve shape retention strength. This allows the bottom portions 61b to withstand the reaction force that crushes the seal member 14 and maintain their shape, thereby reliably preventing water from leaking above or below the floor in the event of a leak from the faucet portion 72. Furthermore, the upper ends of the first wall portion 17, second wall portion 18, and side wall portion 62 that form the storage space 20 are each formed with a receiving portion 21 that receives a protruding piece 8T (see FIG. 5) (described below) that protrudes downward from the inner peripheral edge of the lower end of the cover 8. As shown in FIG. 6, the lower surface 6B of the lower bottom portion 61b of the bottom portions 61a, 61b is located higher than the lower surface 6b of the other bottom portions 61. This is because, in order to ensure that the flange portion 71E and the sealing member 14 can be reliably positioned between the underside 6B of the bottom 61b and the upper surface 9B of the floor 9, the gap between the underside 6B of the bottom 61b and the upper surface 9B of the floor 9 is made larger than the gap between the underside 6b of the bottom 61 and the upper surface 9B of the floor 9 in other parts, and specifically, is made the same as or slightly smaller than the sum of the thickness of the flange portion 71E and the thickness of the sealing member 14.

[0034] As shown in Fig. 7, the faucet unit 72 comprises a faucet body 72A and a generally hemispherical handle 72B (the shape can be freely changed) rotatably attached to the upper end of the faucet body 72A to open and close an openable / closable valve unit (not shown) provided in the faucet body 72A. The upper end of the faucet body 72A protrudes upward from a through-hole 81A in the cover 8, and a male thread 72N is formed on the protruding outer surface. As shown in Fig. 6, the male thread 72N is threadedly engaged with a female thread 26N formed on a cover retaining nut 26, so that the lower end 26A of the cover retaining nut 26 abuts against a lowered upper surface 81a of a top wall 81 of the cover 8 (described later), preventing the cover 8 from moving upward. The handle 72B is connected and fixed to an operating shaft 72b, which operates a valve (not shown), using a screw 24. Rotating the handle 72B rotates the operating shaft 72b integrally, opening and closing the valve. The handle 72B has a recess for inserting the screw 24 and a cap 25 for closing the upper opening of the recess. The handle 72B also has two recesses 72d (see FIG. 4) on its outer periphery that can accommodate fingers. Rotating the handle 72B opens the valve, allowing water from the water supply pipe 10 to flow into the water inlet 73. The more the handle 72B is rotated, the greater the water flow rate. When the handle 72B is rotated minimally, the water flow rate drops to zero, and the water faucet 72 is closed. The handle 72B, which opens and closes the water faucet 7, protrudes upward from the top wall 81 of the cover 8. Therefore, the water faucet 7 can be quickly opened and closed by operating the handle 72B, which protrudes upward from the cover 8, without removing the cover 8. A vertical space is formed between the top surface of the handle 72B and the top surface of the mounting base 64, allowing one hand to be inserted. One hand can be placed in this space to easily rotate the handle 72B. Specifically, the distance from the top surface of the mounting base 64 to the top end surface of the handle 72B is approximately 20 mm, the distance to the center of the recess 72d of the handle 72B is approximately 30 mm, and the distance to the top surface of the top wall 81 of the cover 8 is approximately 45 mm. This allows one hand to be placed between the top surface of the handle 72B and the top surface of the mounting base 64.

[0035] As shown in Figure 1, the rear wall 84 of the cover 8, which covers the rear side of the water faucet 7 in the front-to-rear direction, is located further forward than the rear wall 64b in the front-to-rear direction of the mounting base 64. Moreover, the protruding end (rear end) of the water inlet 73 of the water faucet 7 is located further forward than the rear wall 64b in the front-to-rear direction of the mounting base 64. This makes it difficult to see the water inlet 73 of the water faucet 7 because it overlaps the mounting base 64 when viewed from the left or right direction (left or right), which is perpendicular to the front-to-rear direction, and prevents the water faucet 7 from looking unsightly.

[0036] Water supply port 73 receives water supply from faucet 72 and has a connection part that can be connected to water supply hose 22 for the washing machine (see the water supply hose coiled and stored in FIG. 8).

[0037] The lower part of the water faucet 7 is covered by a first wall part 17, a second wall part 18 and a side wall part 62, and the upper part is covered by a cover 8.

[0038] As shown in Figure 5, the cover 8 is made up of a top wall portion 81 and a front wall portion 82, a left wall portion 83, and a rear wall portion 84 that extend downward from three sides (front, left, and rear sides) of the periphery of the top wall portion 81, and is configured with an open shape on the bottom and right sides. The open end on the right side of the cover 8 is closed by abutting against the inner wall 64a (see Figure 1) of the mounting base 64. In this way, by covering the water faucet 7 with the cover 8, the water faucet 7 is not exposed, improving the appearance of the waterproof pan 5.

[0039] The top wall 81 has a circular through-hole 81A through which the upper end of the faucet body 72A is inserted. The top wall 81 also has an upper surface with a downwardly sloping rearward surface that slopes downward as it moves rearward. Therefore, when water leaking from the washing machine flows onto the top surface of the top wall 81, it is guided to the rear side of the upper surface, falls into the pan body 6, and is guided to the drain outlet 61B. The rear wall 84 has an inverted U-shaped notch 84K that allows the water inlet 73 of the water faucet 7 to protrude outward (rearward) from the outer surface of the rear wall 84 of the cover 8. Because the water inlet 73 of the water faucet 7 protrudes rearward from the outer surface of the rear wall 84 of the cover 8, the water inlet 73 is less visible when the waterproof pan 5 is viewed from the front in the front-to-rear direction, further improving its appearance, and the water supply hose 22 for the washing machine can be quickly connected to and disconnected from the water inlet 73 protruding outward without removing the cover 8. A notch 17K (see Figures 4 and 6) is formed in the first wall 17 to allow the lower end of the water inlet 73 of the water faucet 7 to protrude outward (rearward). The width of the notch 17K is the same as the width of the notch 84K in the rear wall 84 of the cover 8.

[0040] A downwardly projecting, circumferentially continuous protruding piece 8T (see FIG. 5) is formed on the inside of the lower end portions of the front wall portion 82, the left side wall portion 83, and the rear wall portion 84. By engaging this protruding piece 8T with the receiving portion 21 (see FIG. 4), the cover 8 is engaged and fixed to the waterproof pan 5. The front wall portion 82 of this cover 8 and the front wall 64c of the mounting base 64 are flush in the front-to-rear direction (see FIG. 1).

[0041] A drain hose (not shown) that is connected to a washing machine (not shown) is connected to drain outlet 61B. Drain outlet 61B is formed between left and right mounting stands 64, 64 located on the front side, near left mounting stand 64. Drain outlet 61B and water supply valve 7 are aligned between the left and right mounting stands 64, 64 on the front side. This allows the work of connecting the drain hose to drain outlet 61B and the work of connecting water supply hose 22 for the washing machine to water supply valve 7 to be carried out quickly.

[0042] 8, washing machine water supply hose 22 is stored horizontally in a wound state around the center of pan body 6. Water supply hose 22 is in contact at its four outermost points with all of the innermost vertical portions 64T, 64T, 64T, 64T of each of the four mounting bases 64, 64, 64, 64, and vertical portions 64T, 64T, 64T function as holders that can maintain the stored position of water supply hose 22. By storing and holding water supply hose 22 in this manner, a storage container and interference prevention material are not required, compared to, for example, a case in which a washing machine water supply hose stored in a container is temporarily removed from the container to connect the washing machine's water inlet and the water inlet of a water faucet, thereby reducing waste at the construction site and allowing washing machine water supply hose 22 to be immediately grasped and quickly connected to the washing machine's water inlet and the water inlet 73 of the water faucet 7. In Figure 8, water supply hose 22 is simply wound, so that it spreads outward and abuts against all of vertical portions 64T, 64T, 64T, 64T, but to prevent the wound water supply hose 22 from spreading out and abutting against all of vertical portions 64T, 64T, 64T, 64T, the outer diameter of water supply hose 22 wound with a binding device such as string or rope may be made smaller than the outer diameter of water supply hose 22 when abutting against all of vertical portions 64T, 64T, 64T, 64T. In this case, it is preferable that two points of water supply hose 22 abut against at least two of vertical portions 64T, 64T, 64T, 64T to restrict movement of water supply hose 22.

[0043] The procedure for installing the waterproof pan 5 on the floor 9 will now be described. First, insert and connect the water supply pipe 10 into the joint 71 of the water faucet 7, then secure the flange 71C of the joint 71 to the floor 9 with multiple screws 13. Place the ring-shaped seal member 14 so that it covers the top of the screw 13, then insert the pan body 6 through its through-hole 61C into the joint 71 and place it on the floor 9 while aligning it horizontally. The lower flange of the faucet unit 72 (without the handle 72B) is placed vertically over the upper flange of the joint 71, and the two-pronged connecting member 23 (see Figures 6 and 7) is slid horizontally to connect the two. After connection, the faucet unit 72 is restricted from moving vertically but is able to rotate circumferentially. The connecting member 23 is a member that can be easily attached and detached by hand without the need for tools. Next, the cover 8 is placed over the faucet main body 72A from above so that the upper end of the faucet main body 72A passes through the through-hole 81A in the top wall portion 81 and protrudes upward, and the protruding piece 8T of the cover 8 is engaged with the receiving portion 21. After this, the cover retaining nut 26 is screwed onto the protruding male thread portion 72N of the faucet main body 72A to prevent the cover 8 from moving upward. Next, the handle 72B is fitted into the operating shaft portion 72b and fixed with the screw 24, and then the four mounting bases 64 are fixed to the floor 9 with wood screws (not shown) to complete the installation of the waterproof pan 5.

[0044] To replace the pan body 6, first loosen the screw 24 with a screwdriver to remove the handle 72B from the operating shaft 72b. Next, loosen and remove the cover retaining nut 26 with your fingers. At this time, the operating shaft 72b can also be replaced using a wrench or similar tool. Next, remove the cover 8 with your fingers. At this time, the outlet 73 can also be replaced using a wrench or similar tool. During replacement, rotating the cover 8 circumferentially and facing toward you makes replacing the outlet 73 easier. Next, slide the connecting member 23 with your fingers to remove it, and then remove the faucet body 72A by pulling it upward. At this time, the faucet body 72A can also be replaced. The three components—the operating shaft 72b, the outlet 73, and the faucet body 72A—can be replaced without removing the pan body 6 or the joint 71. After removing the faucet body 72A, remove the pan body 6, and install a new pan body 6 to complete the pan body 6 replacement. Furthermore, when the pan body 6 and the joint part 71 are removed, traces of the screw holes remain on the floor 9, and if the pan body 6 and the joint part 71 are not re-fixed carefully, the screw holes may be crushed, which may cause problems with fixing.

[0045] The present invention is not limited to the above-described embodiment, and various modifications are possible without departing from the spirit of the present invention.

[0046] In the above embodiment, the water inlet 73 protrudes rearward from the rear wall 84, but it may also protrude leftward or diagonally rearward left from the left wall 83. Also, the water faucet 7 is installed on the left side of the right-side mounting base 64, but it may also be installed on the right side of the left-side mounting base 64. In this case, the water inlet 73 of the water faucet 7 may protrude rearward from the rear wall 84, or may protrude rightward or diagonally rearward right from the right-side wall. When the water faucet 7 is installed to the right of the left-side mounting base 64, the drain outlet 61B may be formed between the water faucet 7 and the right-side mounting base 64.

[0047] In the above embodiment, the waterproof pan is a pan for placing a washing machine thereon, but it may be a pan for placing a bathtub thereon. Also, the waterproof pan of the present invention may be installed in an entranceway.

[0048] Furthermore, in the above embodiment, the cover 8 is configured to have a rectangular shape in a plan view, but it may have any shape, such as a trapezoidal shape, a circular triangle shape, or the like.

[0049] Furthermore, in the above embodiment, the cover 8 is composed of the top wall portion 81, the front wall portion 82, the left side wall portion 83, and the rear wall portion 84, but the left side wall portion 83 may be omitted and the cover 8 may be composed of the top wall portion 81, the front wall portion 82, and the rear wall portion 84, or the rear wall portion 84 may be omitted and the cover 8 may be composed of the top wall portion 81, the front wall portion 82, and the left side wall portion 83.

[0050] Furthermore, in the above embodiment, the handle 72B protrudes upward, but the handle 72B may protrude forward, or may protrude leftward in the left-right direction when the cover 8 is disposed adjacent to the right-side mounting base 64 at the front side shown in Fig. 1, or, although not shown, may protrude rightward when the cover 8 is disposed adjacent to the left-side mounting base 64 at the front side in Fig. 1. When the handle 72B protrudes forward, it is preferable to position the handle 72B so that it does not protrude forward from the front end of the waterproof pan 5 and come into contact with other objects.

[0051] Furthermore, in the above embodiment, the flange 71C and the joint body 71A are formed as separate bodies, but the flange 71C and the joint body 71A may also be formed as a single body.

[0052] Furthermore, in the above embodiment, the side wall portion 62 is provided on the outer periphery of the bread body 6, but the side wall portion 62 may be omitted.

[0053] Furthermore, in the above embodiment, the water inlet 73 of the water faucet 7 protrudes outside the cover 8, but it may be housed inside the cover 8. In this case, a water supply hose is connected to the water inlet 73 of the water faucet 7 housed inside the cover 8 through an opening formed in the cover 8.

[0054] Alternatively, the waterproof pan may be configured as follows: Note that the names and symbols used in Figures 7 and 9 are written in parentheses. In Figure 9, the parts other than the seal member 14 and the through hole 71K formed in the second cylindrical portion 71b are configured the same as in Figure 7, and parts other than the joint portion 71 are omitted. The pan body (pan body 6) includes a base (base 63 shown in FIG. 1) that can be installed on the upper surface (upper surface 9B) of the floor (floor 9) and is configured to extend in the front-to-back and left-to-right directions, and that has a through hole (through hole 61C) that is positioned above a floor hole (through hole 9A), and a water equipment (joint portion 71) that is positioned facing the floor hole (through hole 9A) and configured to allow water to flow in the vertical direction relative to the floor (floor 9), the base (base 63 shown in FIG. 1) has a through hole edge portion (through hole edge portion 61D) that defines the through hole (through hole 61C), and the water equipment (joint portion 71) is a floor that is placed on the floor hole edge portion (floor hole edge portion 9C) that defines the floor hole (through hole 9A). A waterproof pan having a flange portion (flange portion 71E), the flange portion (flange portion 71E) being placed on the floor hole edge portion (floor hole edge portion 9C), and the through hole edge portion (through hole edge portion 61D) being placed on the flange portion (flange portion 71E), thereby forming a clamping structure in which the flange portion (flange portion 71E) is clamped between the floor hole edge portion (floor hole edge portion 9C) and the through hole edge portion (through hole edge portion 61D), and having a sealing member (sealing member 14) arranged in the clamping structure to seal water leakage from above the pan body (pan body 6) to above and below the floor through the through hole (through hole 61C) and the floor hole (through hole 9A) in the clamping structure.

[0055] To explain the effects of the waterproof pan, In the clamping structure, the through hole edge (through hole edge 61D) of the base (base 63 shown in Figure 1) is positioned on the flange portion (flange portion 71E) of the water equipment (joint portion 71), so that during maintenance, etc., the pan body (pan body 6) can be removed or replaced while leaving the water equipment (joint portion 71). In addition, since a sealing member (sealing member 14) is arranged in the clamping structure, it is possible to prevent water from leaking from above the bread body (bread body 6) onto or below the floor through the through hole (through hole 61C) or the floor hole (through hole 9A).

[0056] As shown in FIG. 7, the seal member 14 is formed in an annular (ring-like) shape and disposed between the through-hole edge portion 61D and the flange portion 71E. The flange portion 71E has flange holes (through holes 71G) for inserting fastening members (screws 13) into the floor hole edge portion (through hole 9A), and the seal member 14 is disposed above the flange holes (through holes 71G). The flange portion 71E has a plurality of flange holes (through holes 71G) arranged on a predetermined imaginary circle, and the seal member 14 is formed in an annular shape so as to cover each flange hole (through hole 71G) on the imaginary circle. A radially inner end 14A of the seal member 14 is located radially inward of the flange holes (through holes 71G). 7, sealing member 14 is formed in the shape of an annular plate having a radial dimension so as to cover each flange hole (through hole 71G) on an imaginary circle, but as long as it is possible to seal between through hole edge portion 61D and flange portion 71E radially inward of the flange holes (through holes 71G), it is not necessary to cover each flange hole (through hole 71G) on the imaginary circle, and an O-ring can be used. Sealing member 14 shown in FIG. 7 has a first portion located on the fastening member (screw 13) and a second portion extending radially inward from the first portion and located on flange portion 71E, and the second portion seals between through hole edge portion 61D and flange portion 71E.

[0057] As shown in FIG. 9, the seal member 14 has an annular first seal portion 14a disposed between the flange portion 71E and the floor hole edge portion 9C. The first seal portion 14a seals radially inward of the flange hole (through hole 71G). The seal member 14 has a second seal portion 14b disposed between the through hole edge portion 61D and the floor hole edge portion 9C. The second seal portion 14b is disposed radially outward of the flange portion 71E. The seal member 14 has a third seal portion 14c that seals the outer peripheral surface of the water pipe (water supply pipe 10) extending downward from the water equipment (joint portion 71). The seal member 14 has a fourth seal portion 14d that connects the first seal portion 14a and the third seal portion 14c. The fourth seal portion 14d covers the entire outer periphery of the water equipment (joint portion 71) inserted into the floor hole (through hole 9A) between the first seal portion 14a and the third seal portion 14c. The inner periphery of the third seal portion 14c is provided with multiple (two in FIG. 9) annular protrusions 14t, 14t that abut against the outer periphery of the water pipe (water supply pipe 10) to form a seal. As mentioned above, the seal member 14 is made of foamed resin such as sponge (it may be soft resin or rubber (including natural rubber or synthetic rubber)).

[0058] The seal member 14 shown in Figure 9 is configured to store water leaking from the joint portion 71 in a space S1 formed between the outer cylinder 71B and the fourth seal portion 14d. Specifically, if the O-rings 11 and 12 that seal between the inside of the water supply pipe 10 and the outside of the joint body 71A become defective due to deterioration or other reasons, the leaked water will accumulate in the space S1. When the accumulated water reaches the upper part of the space S1, it moves into the storage space 20 through the through-hole 71K formed in the second cylindrical portion 71b (see arrow Y).
