[Modes for carrying out the invention]

[0008] <Embodiment> As shown in Figure 1, the toilet handwashing device 10 is attached as a lid to the upper side of the toilet flushing tank 11. The toilet flushing tank 11 is located at the rear of the toilet bowl 12. The toilet flushing tank 11 stores the flushing water that is supplied into the toilet bowl 12.

[0009] In the following explanation, the upper side of the toilet flushing tank 11 will be referred to as the upper side, the lower side as the lower side, the front side as the front, and the rear side as the rear. When viewing the toilet handwashing device 10 from the front, the right side will be referred to as the right, and the left side as the left. In the drawing, the positive direction of the X-axis is the front, the negative direction of the X-axis is the rear, the positive direction of the Y-axis is the upper side, the negative direction of the Y-axis is the lower side, the positive direction of the Z-axis is the right side, and the negative direction of the Z-axis is the left side.

[0010] As shown in Figures 1 to 4, the toilet handwashing device 10 comprises a basin 20, a water outlet 30, and a water passage 50. The water outlet 30 discharges a portion of the water supplied from outside the toilet flushing tank 11 via the water passage 50 into the basin 20. The water received in the basin 20 is discharged from a drain opening 21 formed in the bottom surface 25 of the basin 20 and stored in the toilet flushing tank 11. The drain opening 21 has a cylindrical circumferential surface 21M. The circumferential surface 21M extends vertically downward from the bottom surface 25.

[0011] The bowl portion 20 and the water outlet portion 30 are integrally formed from the same material (such as synthetic resin or ceramics). As shown in Figure 4, the bowl portion 20 has a front portion 22, a rear portion 23, left and right side portions 24, a bottom portion 25, and an outer peripheral portion 26. The height dimension of the rear portion 23 is greater than the height dimension of the front portion 22. The upper ends of the left and right side portions 24 gradually slope downward from the rear end to the front end. The outer peripheral portion 26 surrounds the outer periphery of the bowl portion 20. The outer peripheral portion 26 includes a front portion 27, a rear portion 28, and left and right outer surface portions 29.

[0012] As shown in Figure 2, the water outlet 30 is located in the center of the bowl portion 20 in the left-right direction. The water outlet 30 is located at the upper end of the rear surface portion 23 of the bowl portion 20. The water outlet 30 is formed by a part of the rear surface portion 23 of the bowl portion 20 protruding forward (see Figure 4).

[0013] As shown in Figures 2 and 4, the water outlet section 30 has a front wall section 31, a rear wall section 32, left and right side walls 33, and an upper wall section 34. The front wall section 31 and the left and right side walls 33 are continuous with the rear surface section 23 of the bowl section 20. The rear wall section 32 is formed by the back surface section 28 of the outer peripheral surface section 26 of the bowl section 20. The upper wall section 34 extends forward from the upper end position of the back surface section 28.

[0014] As shown in Fig. 4, the outer surface 31S of the front wall portion 31 faces the pot portion 20. The outer surface 31S of the front wall portion 31 is an inclined surface that slopes downward toward the rear. The outer surface 31S of the front wall portion 31 faces the front surface portion 22 of the pot portion 20. The front wall portion 31 and the front surface portion 22 are substantially parallel. An opening for water discharge (referred to as the water discharge opening 35) is formed in the front wall portion 31 to expose the water outlet 51 formed on the tip surface 53F of the water passage portion 50. The water discharge opening 35 is circular when viewed from the front in the flow path direction (see Fig. 6). The water discharge portion 30 discharges water downward from the water outlet 51.

[0015] As shown in Fig. 5, a region along the peripheral surface 36 of the water discharge opening 35 in the inner surface 31U of the front wall portion 31 is a recessed portion 37 that is recessed more than other regions. The recessed portion 37 has a sealing surface 38 that adheres to a sealing member 52 described later. The sealing surface 38 has an annular shape (see Fig. 9).

[0016] As shown in Fig. 4, the inside of the water discharge portion 30 is the upper part of a storage space 39 that houses the water passage portion 50. The upper part of the storage space 39 is surrounded by the front wall portion 31, a cover 45 described later, the upper wall portion 34, and the left and right side wall portions 33. The lower part of the storage space 39 is formed between the rear surface portion 23 of the pot portion 20 and the rear wall portion 32. The storage space 39 extends in the left - right direction between the rear surface portion 23 of the pot portion 20 and the rear wall portion 32 and is open downward. A boss 41 for fixing the water passage portion 50 is provided in the storage space 39 (see Fig. 9). The boss 41 projects rearward from the inner surface 31U of the front wall portion 31.

[0017] As shown in Fig. 3, an opening 44 is formed in the rear wall portion 32. The opening 44 opens the storage space 39 to the rear of the rear wall portion 32. The entire circumference of the opening 44 is closed. The opening 44 is rectangular. The dimension of the opening 44 in the left - right direction is larger than the dimension of the opening 44 in the up - down direction. The opening 44 is closed by a cover 45 (see Fig. 4). In the state of being attached to the opening 44, the cover 45 constitutes a part of the rear wall portion 32.

[0018] As shown in Fig. 4, the water passage part 50 is stored in the storage space 39. The water passage part 50 is formed of a hard material such as synthetic resin. The water passage part 50 is fixed to the boss 41 in the storage space 39 by a fixture 42 (see Fig. 3). The lower end part of the water passage part 50 is connected to a water supply pipe (not shown) in the toilet washing tank 11.

[0019] As shown in Fig. 4, the water passage part 50 has a first water passage part 66 extending rearward from the outlet 51, and a second water passage part 67 extending downward along the back surface of the bowl part 20 from the rear end of the first water passage part 66. The first water passage part 66 and the second water passage part 67 are substantially perpendicular to each other.

[0020] As shown in Fig. 4, the first water passage part 66 has an outflow part 53. The outflow part 53 is provided at the front end part of the first water passage part 66 and protrudes downward. An outlet 51 and an outflow path 55 are formed in the outflow part 53. The outlet 51 opens on the front end surface 53F of the outflow part 53. The outflow path 55 extends obliquely upward from the outlet 51.

[0021] A first water passage 57 connected to the upstream end of the outflow path 55 is formed in the first water passage part 66. The first water passage 57 extends substantially horizontally from the upstream end of the outflow path 55 toward the rear side. The flow cross-sectional area of the first water passage 57 becomes narrower on the way from the upstream side to the downstream side.

[0022] A second water passage 58 extending substantially vertically downward from the upstream end of the first water passage 57 is formed in the second water passage part 67. The flow cross-sectional area of the second water passage 58 is narrower on the downstream side than on the upstream side.

[0023] The water passage part 50 is formed by connecting two members divided in the flow path direction into one. The two members are a first member 61 including the outflow part 53, and a second member 62 connected to the rear side of the first member 61. The first member 61 and the second member 62 are connected to each other and fixed by an adhesive.

[0024] As shown in Figure 5, the outlet section 53 has a tip section 53A and a rear section 53B that follows behind the tip section 53A. The tip section 53A penetrates the water discharge opening 35 and protrudes outward from the front wall section 31. The rear section 53B is located in the storage space 39. The rear section 53B has a sealing surface 59 that is in close contact with the sealing member 52. The sealing surface 59 forms an annular shape that surrounds the outer circumferential surface of the tip section 53A (see Figure 8).

[0025] As shown in Figure 7, the sealing member 52 is provided at the front end of the water passage section 50. The sealing member 52 has an annular shape that surrounds the tip 53A of the outlet section 53. The sealing member 52 is interposed between the sealing surface 59 of the rear section 53B and the sealing surface 38 of the peripheral edge of the water discharge opening 35 (see Figure 5).

[0026] As shown in Figure 5, the tip surface 53F of the outflow section 53 protrudes outward from the outer surface 31S of the front wall section 31. The tip surface 53F of the outflow section 53 is approximately parallel to the outer surface 31S of the front wall section 31. The tip surface 53F of the outflow section 53 is inclined with respect to the flow direction of the outlet 51. In other words, the intersection angle 53α between the tip surface 53F of the outflow section 53 and the center line 51L extending in the flow direction through the center 51C of the outlet 51 is an angle different from 90 degrees. The intersection angle 53α shown in Figure 5 is less than 90 degrees.

[0027] As shown in Figure 5, the outer edge of the tip surface 53F of the outflow section 53 is rounded. The rounding is formed around the entire circumference of the outer edge. The upper region of the outer edge of the tip surface 53F of the outflow section 53 has a gentler curve than the lower region. The lower region of the outer edge of the tip surface 53F of the outflow section 53 has a sharper curve than the upper region.

[0028] The radius of curvature R of the rounded edge is smaller on the lower side of the outer edge than on the upper side of the outer edge. The radius of curvature R of the rounded edge is the radius of curvature in the cross section that extends in the flow direction through the center 51C of the outlet 51. The upper region of the outer edge of the tip surface 53F is the region of the outer edge of the tip surface 53F that is above the height position of the center 51C of the outlet 51. The lower region of the outer edge of the tip surface 53F is the region of the outer edge of the tip surface 53F that is below the height position of the center 51C of the outlet 51. The radius of curvature R of the outer edge of the tip surface 53F of the outflow section 53 gradually decreases from the upper end of the outer edge to the lower end of the outer edge.

[0029] As shown in Figures 5 and 6, the outlet section 53 has a plurality of plate sections 71. The plurality of plate sections 71 radiate from a cylindrical section 78 formed in the center of the outlet passage 55 and extend in the flow direction of the outlet passage 55. Each plate section 71 extends from the vicinity of the tip surface 53F to the first water channel 57. As shown in Figure 6, the plate sections 71 are arranged around the cylindrical section 78 at equal angular intervals. Below the outlet 51, there is a space 72 formed between adjacent plate sections 71.

[0030] As shown in Figure 6, when viewing the outlet 51 from the direction of arrow A in Figure 5, the center 51C of the outlet 51 and the center 35C of the water discharge opening 35 are the same. Arrow A is directed from front to back in a direction parallel to the flow direction of the outflow passage 55.

[0031] As shown in Figure 4, the outlet 51 discharges water toward the bowl 20. The main stream of water discharged from the outlet 51 collides with the front surface of the circumferential surface 21M of the drain outlet 21, as indicated by the arrows in Figure 4. In other words, the majority of the water discharged from the outlet 51 (the largest amount of water) collides with the front surface of the circumferential surface 21M of the drain outlet 21. A portion of the water discharged from the outlet 51 (a small amount of water) may collide with other parts. The front surface of the circumferential surface 21M of the drain outlet 21 is the front area when the circumferential surface 21M of the drain outlet 21 is divided into front and rear sides with respect to the center in the front-rear direction.

[0032] As shown in Figure 7, an upper rib 76 that protrudes upward is provided on the upper surface of the first water passage section 66. The upper rib 76 is formed on the upper surface of the outlet section 53. When viewed from the left or right, the upper rib 76 has a triangular shape. The upper surface of the upper rib 76 is approximately parallel to the portion of the upper surface of the first water passage section 66 that is behind the outlet section 53.

[0033] As shown in Figure 8, the upper rib 76 is positioned in the left-right center of the first water passage section 66. An overhang 77 is provided on the upper surface of the upper rib 76. The overhang 77 extends outwards on both the left and right sides of the upper rib 76.

[0034] The second water passage section 67 has an upper section 67A and a lower section 67B. The outer shape of the upper section 67A is a rectangular prism, as shown in Figure 9. The outer shape of the lower section 67B is cylindrical. A flange 75 is provided between the upper section 67A and the lower section 67B.

[0035] As shown in Figure 7, a lower rib 73 is provided on the front surface of the second water passage section 67, projecting forward. The lower rib 73 extends downward from the flange section 75. The front surface of the lower rib 73 slopes forward from the top to the bottom. A projection 74 is formed on the front surface of the lower rib 73. The projection 74 is located at the lower end of the lower rib 73. The projection 74 has a rounded dome shape. As shown in Figure 8, the lower rib 73 is positioned in the center of the second water passage section 67 in the left-right direction. The lower rib 73 extends linearly in the vertical direction.

[0036] As shown in Figures 3 and 7, the length dimension L1 of the second water passage 67 is greater than the maximum opening width L2 of the opening 44. The length dimension L1 of the second water passage 67 is the length from the upper end to the lower end of the second water passage 67. The maximum opening width L2 of the opening 44 is the length of the diagonal of the opening 44.

[0037] As shown in Figure 9, the water-conducting section 50 is positioned in the storage space 39 through the opening 44. Specifically, the water-conducting section 50 is inserted into the storage space 39 from its lower end first, in an inclined position along the diagonal of the opening 44.

[0038] The second water passage section 67 has a fixing section 68 which is fixed to the boss 41 of the front wall section 31 by a fixing device 42. The fixing section 68 is provided on the upper part 67A of the second water passage section 67. As shown in Figure 8, there is a pair of fixing sections 68 on the left and right sides. The fixing section 68 is cylindrical in shape and houses the fixing device 42 inside.

[0039] The embodiment configured as described above provides the following effects. The toilet handwashing device 10 has a bowl portion 20, an outlet portion 53, and a front wall portion 31. An outlet 51 is formed on the tip surface 53F of the outlet portion 53, which discharges water toward the bowl portion 20. A water discharge opening 35 is formed on the front wall portion 31, which faces outwards towards the outlet 51. The tip surface 53F of the outlet portion 53 protrudes outwards from the outer surface 31S of the front wall portion 31. With this configuration, when the water discharge is stopped, the water remaining in the outlet 51 tends to fall straight down from the tip surface 53F of the outlet portion 53. Therefore, after stopping the water discharge, it is less likely for the water in the outlet 51 to run down into the bowl portion 20.

[0040] In the cross-section of the outlet 51 that extends in the flow direction through the center 51C, the radius of curvature R of the outer edge of the tip surface 53F of the outflow section 53 is smaller on the rear side of the outer edge than on the front side. With this configuration, the rear side of the outer edge of the tip surface 53F of the outflow section 53 is more pointed than the front side, so when the water discharge is stopped, the water remaining in the outlet 51 tends to fall straight down from the tip surface 53F of the outflow section 53. Therefore, after stopping the water discharge, it is less likely for the water in the outlet 51 to run down into the bowl section 20. On the other hand, since the radius of curvature R on the front side of the outer edge of the tip surface 53F is large, it is less likely for a rag or the like to get caught on the outer edge of the tip surface 53F when cleaning.

[0041] The outer surface 31S of the front wall portion 31 is inclined downward toward the rear. The radius of curvature R of the outer edge of the tip surface 53F of the outflow portion 53 gradually decreases from the upper end of the outer edge toward the lower end of the outer edge. This configuration improves the appearance of the toilet handwashing device 10 when viewed from the front.

[0042] The tip surface 53F of the outflow section 53 is inclined with respect to the flow direction of the outlet 51. With this configuration, the tip surface 53F of the outflow section 53 can be made parallel to the outer surface 31S of the front wall section 31. Therefore, the aesthetic design of the toilet handwashing device 10 can be improved.

[0043] The main stream of water flowing out from the outlet 51 collides with the front surface of the drain opening 21 formed in the basin 20. With this configuration, the water flowing out from the outlet 51 is less likely to splash outside the basin 20, thus improving the user experience of the toilet handwashing device 10.

[0044] When viewing the outlet 51 from the front in the direction of the flow path, the center 51C of the outlet 51 and the center 35C of the water discharge opening 35 are the same. This configuration improves the appearance of the toilet handwashing device 10 when viewed from the front.

[0045] The toilet handwashing device 10 has a water passage section 50 that passes water through the outlet 51. The water passage section 50 has a first water passage section 66 that extends rearward from the outlet 51, and a second water passage section 67 that extends downward from the rear end of the first water passage section 66 along the back surface of the basin section 20. A lower rib 73 that protrudes forward is provided on the front surface of the second water passage section 67. With this configuration, when attaching the water passage section 50 to the back side of the basin section 20, the water passage section 50 can be easily attached by bringing the lower rib 73 into contact with the back surface of the basin section 20. When the front end surface 53F of the outflow section 53 is pushed to the rearward side during cleaning, etc., the lower rib 73 will come into contact with the back surface of the basin section 20, preventing the water passage section 50 from rattling. In this case, since an upper rib 76 is provided on the upper surface of the first water passage section 66, the upper rib 76 may come into contact with the upper wall 34 of the water discharge section 30. The upper rib 76, together with the lower rib 73, prevents rattling of the water passage 50.

[0046] The water passage section 50 has an outflow channel 55 that extends diagonally upward from the outlet 51. The outflow channel 55 has a plurality of plate sections 71. The plurality of plate sections 71 extend radially from the center of the outflow channel 55 in the direction of the flow path of the outflow channel 55. A space section 72 is located below the outlet 51. The space section 72 is formed between adjacent plate sections 71. With this configuration, water from the outlet 51 is less likely to adhere to the plate sections 71 due to surface tension, thus improving the drainage of water from the outlet 51. Therefore, water from the outlet 51 is less likely to run down into the bowl section 20.

[0047] <Other Embodiments> This disclosure is not limited to the embodiments described above and in the drawings, and the technical scope of this disclosure also includes, for example, the following embodiments. (1) In the above embodiment, the outlet section 53 is formed integrally with the water passage section 50. However, the outlet section may be molded separately from the water passage section.

For example, the water passage section may be stored in the storage space from below, or from either the left or right direction. (3) In the above embodiment, the water passage section 50 has two members divided in the direction of the flow path. However, the water passage section does not have to be divided in the direction of the flow path, or it may have three or more members divided in the direction of the flow path. (4) In the above embodiment, the outer surface 31S of the front wall portion 31 is inclined downward toward the rear. However, the outer surface of the front wall portion may be substantially horizontal or substantially vertical. (5) In the above embodiment, the outflow passage 55 extends diagonally upward from the outlet 51. However, the outflow passage may extend vertically, for example, or horizontally. (6) In the above embodiment, the tip surface 53F of the outlet section 53 is inclined with respect to the flow direction of the outlet 51. However, the tip surface of the outlet section may be perpendicular to the flow direction of the outlet. (7) In the above embodiment, the water flowing out from the outlet 51 collides with the front surface inside the drain opening 21 formed in the bowl portion 20. However, the water flowing out from the outlet may collide with any position near the drain opening. (8) In the above embodiment, when the outlet 51 is viewed from the front in the flow direction of the outlet 51, the center 51C of the outlet 51 and the center 35C of the water discharge opening 35 are the same. However, the center of the outlet and the center of the water discharge opening may be offset from each other. (9) In the above embodiment, a lower rib 73 is provided on the front surface of the second water passage section 67. However, the rib is not limited to this, and it is not necessary to provide a rib on the front surface of the second water passage section, or the position and shape of the rib may be changed according to the shape of the water passage section. (10) In the above embodiment, the radius of curvature R of the outer edge of the tip surface 53F of the outflow section 53 gradually decreases from the upper end of the outer edge to the lower end of the outer edge. However, the radius of curvature of the outer edge of the tip surface of the outflow section does not have to continue to change gradually from the upper end of the outer edge to the lower end of the outer edge. For example, the radius of curvature of the outer edge of the tip surface of the outflow section may have a portion that does not change between the upper end and the lower end of the outer edge, or it may have a portion that changes abruptly.
