The supply pipe fixing portion 87 is provided so as to project outward from the connection chamber 4. The supply pipe fixing portion 87 corresponds to the connecting portion. A connection chamber 4 is provided between the supply pipe fixing portion 87 and the tank storage portion 81. The connection chamber 4 and the tank storage unit 81 communicate with each other.

As shown in FIG. 9, a connecting pipe 872 is fixed to the supply pipe fixing portion 87. The connecting pipe 872 is a tubular member that connects the supply pipe 22 of the liquid tank 2 and the ejector 174. The insertion hole 871 of the connecting pipe 872 is open to the connecting chamber 4 side. The connecting pipe 872 has a pipe line bent downward from the insertion hole 871. As shown in FIGS. 9 and 10, the supply pipe fixing portion 87 is formed with a through hole 874 penetrating in the vertical direction H. A connecting pipe 872 is inserted in the through hole 874. The lower end opening of the connecting pipe 872 projects downward from the through hole 874 and is connected to the resin connecting part 875. The connecting component 875 is connected to the connecting tube 171. The downstream end of the connecting tube 171 is connected to a pump (not shown). The pump is connected to the ejector 174. A pipe cover 873 is fixed to the upper part of the supply pipe fixing portion 87 with a screw 90. The pipe cover 873 covers the upper part of the supply pipe fixing portion 87. The upper portion of the connecting pipe 872 is integrally formed with the pipe cover 873.

The supply pipe 22 of the liquid tank 2 is detachably connected to the insertion hole 871. The supply pipe 22 is connected to the ejector 174 via a connecting pipe 872, a connecting component 875, a connecting tube 171 and a pump. As shown in FIG. 6, the insertion hole 871 is arranged on the second side wall 44 side of the first side wall 43 with respect to the central portion.

The bottom portion 41 is provided with a liquid receiving portion 6. The liquid receiving portion 6 is a portion for temporarily storing the liquid dripping from the supply pipe 22 when the supply pipe 22 is pulled out from the insertion hole 871 of the supply pipe fixing portion 87 in order to remove the liquid tank 2 from the tank storage portion 81. Is. The liquid receiving portion 6 is formed on the first side wall 43 side of the bottom portion 41.

A weir portion 7 is provided on the bottom portion 41. The weir portion 7 is formed so as to project upward on the bottom portion 41. The weir portion 7 is formed substantially parallel to the opening edge 421 of the opening 42 at a position away from the opening edge 421 of the opening 42 toward the first side wall 43 side. The first end 71 of the weir portion 7 is connected to the second side wall 44. The weir portion 7 extends from the first end 71 toward the third side wall 45. The second end 72 of the weir portion 7 is separated from the third side wall 45. The length of the weir portion 7 is shorter than the opening width of the opening portion 42. The length of the weir portion 7 is longer than the diameter of the insertion hole 871. The second end 72 of the weir portion 7 is located on the third side wall 45 side of the insertion hole 871. As a result, the liquid receiving portion 6 can receive the leaked liquid dripping from the insertion hole 871.

As shown in FIG. 8, the liquid receiving portion 6 is composed of a region surrounded by the first side wall 43, the weir portion 7, and the second side wall 44. As shown in FIGS. 6 and 7, the liquid receiving portion 6 is provided below the insertion hole 871.

An outflow portion 61 is formed between the second end 72 of the weir portion 7 and the third side wall 45. The outflow portion 61 is a flow path through which the leaked liquid flows out when a large amount of leaked liquid is accumulated in the liquid receiving portion 6. The outflow portion 61 is at the same height as the bottom portion 41 or lower than the bottom portion 41. The outflow portion 61 is formed at a position deviated from below the insertion hole 871. Since the place where the leaked liquid collected in the liquid receiving portion 6 flows out is shorter than the opening width of the opening 42, the leaked liquid dripping from the insertion hole 871 can be temporarily stored in the liquid receiving portion 6. When a large amount of leaked liquid is accumulated in the liquid receiving portion 6, it is guided to the outflow portion 61. As a result, when the amount of leaked liquid is small, the leaked liquid accumulates in the liquid receiving portion 6, and when a large amount of leaked liquid accumulates in the liquid receiving portion 6, it drips from the outflow portion 61. Therefore, as compared with the case where the leaked liquid drips from the entire opening 42, the area where the leaked liquid adheres to the inside of the tank case 10 can be suppressed, and the labor for cleaning can be reduced.

The bottom portion 41 is provided with a guide protrusion 3. The guide protrusion 3 is formed so as to project from the bottom 41 from the second end 72 of the weir 7 to the opening edge 421. The outflow portion is partitioned by the guide protrusion 3. Therefore, it is possible to prevent the leaked liquid from dripping over the entire area of the opening 42.

A vertical guide protrusion 31 is formed on the inner surface of the wall portion 82 of the upper component 8. The vertical guide protrusion 31 is formed so as to extend downward continuously with the guide protrusion 3. The vertical guide protrusion 31 functions as a weir to prevent the diffusion of the leaked liquid dripping on the wall portion 82 of the upper component 8. The vertical guide protrusion 31 is provided from the upper end to the lower end of the wall portion 82. As shown in FIG. 7, the lower end of the wall portion 82 of the upper component 8 is arranged on the same surface as the upper end 511 of the side wall 51 of the lower component 5. Therefore, the leaked liquid does not flow out to the outside of the lower component 5, but drips downward along the vertical guide protrusion 31. The surface of the side wall 51 separated by the vertical guide protrusion 31 is referred to as a vertical outflow portion 63.

The configuration in which the vertical guide protrusion 31 is provided continuously with the protrusion 3 is an example, and is not an essential configuration. For example, the vertical guide protrusion 31 may be provided at a position away from the protrusion 3. For example, the weir portion 7 and the vertical guide protrusion 31 may be provided without the protrusion 3.

As shown in FIG. 8, at the corners between the upper ends of the side wall 51, an upper end surface 58 which is substantially triangular in a plan view and is at the same height as the upper end of the side wall 51 and along the lateral direction is formed. An inclined surface 57 inclined downward from the upper end surface 58 is formed at a corner portion between the side walls 51 of the lower component 5.

An upper end surface 58 and an inclined surface 57 are provided below the vertical outflow portion 63. The leaked liquid dripping along the vertical outflow portion 63 drips downward along the upper end surface 58 and the inclined surface 57. As a result of providing the upper end surface 58 and the inclined surface 57, for example, when a large amount of leaked liquid flows out, the leaked liquid that has reached the lower end of the upper end surface 58 is guided to the upper end surface 58 and the inclined surface 57. Therefore, it is possible to prevent the leaked liquid from entering the gap between the contact portion between the upper component 8 and the lower component 5.

Next, a mode of use of the toilet bowl device 200 will be described. When the liquid tank 2 is stored in the tank case 10, the direction of the supply pipe 22 is aligned with the connection chamber 4, and the tank body 25 is inserted into the tank storage portion 81 from above the tank case 10. When the lower surface 254 of the supported portion 253 of the tank body 25 is supported by the support portion 89 of the tank storage portion 81, the supply pipe 22 and the insertion hole 871 are coaxially arranged. When the supply pipe 22 is arranged in the connection chamber 4, the lever 24 is moved to project the supply pipe 22 from the pipe holder 23, and the discharge end 221 is inserted into the insertion hole 871, the supply pipe 22 and the connecting pipe 872 are connected. Be connected. When the supply pipe 22 and the connecting pipe 872 are connected, the liquid can be supplied from the liquid tank 2 to the ejector 174 by the pump.

When the liquid tank 2 is removed from the tank case 10, when the lever 24 is moved in the direction opposite to that at the time of attachment and the supply pipe 22 is retracted into the pipe holder 23, the connection between the supply pipe 22 and the connecting pipe 872 is released. NS. After this, the liquid tank 2 can be removed from the tank case 10. When the supply pipe 22 is removed from the insertion hole 871, the liquid remains in the supply pipe 22 and the connecting pipe 872. Therefore, when the supply pipe 22 is removed from the insertion hole 871, the liquid remaining in the connecting pipe 872 may flow out from the insertion hole 871.

The leaked liquid flowing out of the insertion hole 871 drips downward due to gravity and reaches the liquid receiving portion 6 of the bottom portion 41 along the first side wall 43. The leaked liquid that has reached the liquid receiving portion 6 is blocked by the weir portion 7. When the liquid is a detergent, for example, since the viscosity of the liquid is higher than that of water or the like, when the amount of leaked liquid is small, it tends to stay in the liquid receiving portion 6. At this stage, only the liquid receiving portion 6 needs to be cleaned. When the amount of the leaked liquid in the liquid receiving portion 6 increases and the leaked liquid reaches the outflow portion 61 side, the leaked liquid drips downward along the wall portion 82 of the upper component 8. At this time, the guide protrusion 3 and the vertical guide protrusion 31 limit the flow path of the leaked liquid to a narrow range with respect to the opening width of the opening 42. When the leaked liquid reaches the lower end of the upper component 8, the leaked liquid collects in the recess 53 along the upper end surface 58 and the inclined surface 57. Since the lower component 5 has a bottomed shape, even if the leaked liquid reaches the inside of the lower component 5, it does not flow out of the tank case 10. Therefore, the user only needs to clean the inside of the tank case 10.

A storage opening 109 of the liquid tank 2 is opened on the upper surface of the second cover 106. The tank case 10 is arranged along the opening edge of the storage opening 109. The tank case 10 opens upward when the first cover 105 of the functional portion 150 is removed. Therefore, when the liquid tank 2 is removed as described above, the inside of the tank case 10 is exposed. In this state, the user wipes off the leaked liquid.

According to the toilet bowl device according to the embodiment, the area where the leaked liquid of the liquid tank 2 adheres can be limited and the burden of cleaning can be reduced by a simple configuration. Since it is difficult for the leaked liquid to enter the outside of the tank case 10, the cleaning target area is inside the tank case 10. Since the inside of the tank case 10 is a portion exposed during the work of attaching and detaching the liquid tank 2, it is easy for the user to see and clean.

Next, a modified example of the toilet bowl device 200 will be described with reference to FIGS. 10 to 15. In the following description, the same components as those already described will be designated by the same reference numerals, and duplicate description will be omitted.

As in the modified example shown in FIG. 10, the bottom portion 41 is inclined so as to increase in height from the end portion 411 on the supply pipe fixing portion 87 side toward the end portion 412 on the tank storage portion 81 side, and the liquid receiving portion 6A. May be formed. With this configuration, a wide liquid receiving portion 6A is formed on the bottom portion 41, and the amount of leaked liquid can be increased. In this modification, similarly to the weir portion 7 of the above embodiment, the end portion 412 of the bottom portion 41 functions to block the leaked liquid. As a result of the liquid receiving portion 6 having a high storage amount, it takes time for the leaked liquid to overflow from the liquid receiving portion 6A and drip from the bottom portion 41 to the tank storage portion 81, and the labor for cleaning can be reduced. The liquid receiving portion 6A may be provided at least below the insertion hole 871. The liquid receiving portion 6A may be formed so that the height of the bottom portion 41 is higher on the third side wall 45 side than on the second side wall 44 side.

As in the modified example shown in FIG. 11, the liquid receiving portion 6B may be formed by projecting the boundary portion between the bottom portion 41 and the tank storage portion 81 higher than the bottom portion 41 on the supply pipe fixing portion 87 side. In other words, the supply pipe fixing portion 87 side of the bottom portion 41 may be formed in a recessed manner. In this case, the boundary portion between the bottom portion 41 and the tank storage portion 81 functions as a weir portion.

As in the modified example shown in FIG. 12, the guide protrusion 3C and the vertical guide protrusion 31C may be arranged on the same surface as the side surface 251 of the tank body 25. As a result, since the tank main body 25 is separated from the outflow portion 61, the leaked liquid flowing out from the outflow portion 61 is unlikely to adhere to the tank main body 25. As a result, the leaked liquid can be smoothly guided below the outflow portion 61 along the first wall portion 82. It is possible to save the trouble of cleaning the tank body 25. As shown in FIG. 12, when the corners of the tank body 25 form an R surface in a plan view, a wide gap is formed between the outflow portion 61 and the tank body 25, so that the leaked liquid leaks to the tank body. It is possible to prevent the 25 from adhering to the 25 more effectively.

As in the modified example shown in FIG. 13, the descending portion 62 may be formed in the outflow portion 61. The lowering portion 62 is formed with a plurality of step portions in a stepped manner from the bottom portion 41 toward the tank storage portion 81, for example. By providing the outflow portion 61 with a lowering portion 62 having a height different from that of the bottom portion 41, the bottom portion 41 and the outflow portion 61 are separated, and it is possible to prevent the leaked liquid from spreading outside the outflow portion 61. A guide protrusion 3D may be provided on the uppermost side of the lowering portion 62. By providing the guide protrusion 3D, the amount of liquid stored in the liquid receiving portion 6 can be secured, and the labor for cleaning the leaked liquid can be reduced. As shown in FIG. 13, the guide protrusion 3D extends from the second end 72 of the weir portion 7 toward the first side wall 43, and also faces the tank storage portion 81 side from the second end 72 of the weir portion 7. It may be an example of extending. In addition to the example shown in FIG. 13, the descending portion 62 may be a linear inclined surface, a curved surface, or the like.

A fixed portion 88 projecting laterally is provided on the outer periphery of the lower portion of the upper component 8. The lower end portion of the upper component 8 is inserted into the connection recess 56, and the fixed portion 88 is placed on the fixing portion 55 at the upper end outer edge of the connection recess 56 and fixed by the screw 90. The length from the lower surface 881 of the fixed portion 88 to the lower end 83 of the upper component 8 in the vertical direction H is shorter than the length from the fixing portion 55 of the lower component 5 to the lower surface 561 of the connecting recess 56. With this configuration, since the lower end of the upper component 8 is separated from the lower component 5, it is difficult for the leaked liquid to infiltrate the outside of the upper component 8 due to surface tension. Since the connection recess 56 is formed by being recessed inward from the fixing portion 55, the leaked liquid does not leak to the outside of the lower component 5. If the dimensions of the connection recess 56 and the upper component 8 are set to such an extent that a gap S2 is formed between the inner surface of the connection recess 56 and the outer peripheral surface of the lower component 5, the liquid leakage prevention effect can be further enhanced.

As in the modified example shown in FIG. 15, the liquid receiving portion 6 may be configured to provide only the weir portion 7F without providing the guide protrusion and the vertical guide protrusion.
