Description

The present disclosure relates to a toilet bowl cleaning device.

One of the functional parts of the toilet bowl cleaning device is to supply a certain amount of cleaning water into the toilet bowl body after use, in order to prevent dirt from adhering to the toilet bowl body and odor from the sewer pipe. Functional parts are known. This flushing water is called make-up water and forms a water seal that is stored within the toilet bowl body. The make-up water is used by branching off a portion of the cleaning water that is supplied to the cleaning tank in the toilet bowl cleaning device.

Conventionally, there is known a toilet flushing device in which an operating member for adjusting the amount of make-up water protrudes from the bottom of the flushing tank (see, for example, Patent Document 1).

Japanese Patent Application Publication No. 11-324060

Adjustment of the amount of makeup water is performed, for example, when installing a toilet device, and is not performed frequently. Nevertheless, in the above-mentioned conventional toilet bowl cleaning device, an operating member for adjusting the amount of supplementary water is provided to protrude outside the low tank, and is always visible to the user. Therefore, the conventional toilet bowl cleaning device described above has a problem from the viewpoint of improving the design.

In addition to the functional unit that supplies makeup water, the toilet bowl cleaning device has various functional units that are operated by operating members. Therefore, there is a need for a toilet bowl cleaning device in which the operating member for operating the functional parts of the toilet bowl cleaning device is not visible to the user when no operation is required, and can be easily operated when the toilet bowl cleaning device is operated.

The present disclosure provides a toilet flushing device that includes a flushing tank to which flushing water is supplied, a tank cover that covers the flushing tank, a lifting device that raises and lowers the tank cover between a fixed position and a raised position that is located above the fixed position, and an operating member that is located inside the tank cover and operates a functional section, the operating member being covered by the tank cover when the tank cover is in the fixed position, and being exposed and operable below the tank cover when the tank cover is in the raised position.

The hand-washing bowl section 82 is formed from a part of the upper cover section 71 of the tank cover 7. The hand-washing bowl section 82 receives the hand-washing water discharged from the hand-washing water discharge section 81. A wash water outlet (not shown) is formed at the bottom of this hand-washing bowl section 82.

As shown in FIG. 2, the lifting device 9 raises and lowers the front base part (not shown), which is located inside the tank cover 7 and forward of the base member 3, relative to the toilet body 2. The front base part is located on the upper surface of the toilet body 21 in front of the base member 3, and is equipped with functional parts such as a flushing nozzle and electrical parts (none of which are shown) that are equipped to the toilet flushing device 1. The lifting device 9 raises and lowers the front base part within a certain distance range, thereby positioning the tank cover 7, toilet seat 22, and toilet lid 23 in either a fixed position before lifting (see FIG. 2) or a raised position after lifting (see FIG. 5). However, the lifting device 9 does not raise or lower the base member 3.

The tank cover 7 placed in a fixed position covers the periphery of the base member 3, as shown in FIG. At this time, the base member 3 is not exposed to the outside of the toilet bowl cleaning device 1 and is not visible to the user. The tank cover 7 placed in the raised position exposes at least a portion of the base member 3 to the outside of the toilet bowl cleaning device 1, as shown in FIG.

As shown in FIGS. 2 and 5, the elevating device 9 includes an elevating operation lever member 91 and an elevating mechanism section 92. In this embodiment, the lifting device 9 raises and lowers the front base portion and the tank cover 7 by manually operating the lifting operation lever member 91.

The elevating/lowering operation lever member 91 is arranged on the upper surface of the front base portion. The elevating/lowering operation lever member 91 has an elevating/lowering operating portion 911 that is exposed laterally from the lower end portion on the front side of the lower cover portion 72 of the tank cover 7 .

The elevating mechanism section 92 has a telescopic shaft mechanism section 921. The telescopic shaft mechanism section 921 has a compression spring member (not shown). The telescopic shaft mechanism section 921 expands by the expansion of the compression spring member when the elevating/lowering operation section 911 of the elevating/lowering operation lever member 91 is pushed in by the operator. As a result, the elevating mechanism section 92 raises the tank cover 7 placed at the fixed position to the raised position together with the front base section.

In the toilet bowl cleaning device 1 of this embodiment, when the tank cover 7 is placed in a fixed position by the lifting device 9, the base member 3 is covered with the tank cover 7, as shown in FIG. Do not expose to the outside. Therefore, the operating opening 322 provided in the left guide wall 321 of the base member 3 and the operating knob 62 inside the operating opening 322 are not visible.

However, when the tank cover 7 is placed in the raised position by the lifting device 9, at least the left guide wall portion 321 of the base member 3 is exposed below the tank cover 7 in the lateral direction, as shown in FIG. The exposed portion 100 of the base member 3 exposed at this time includes an operating opening 322. Therefore, the operation knob 62 of the makeup water spouting section 6 is exposed inside the operation opening 322 so as to be operable.

After the operation knob 62 is exposed, the operator who adjusts the amount of make-up water can insert his/her finger through the exposed operation opening 322 and rotate the operation knob 62. This adjusts the amount of make-up water. Because the operation opening 322 and the operation knob 62 are located laterally below the tank cover 7, the operator can easily access the operation knob 62. Therefore, the operator can easily operate the operation knob 62. After adjusting the amount of make-up water, as shown in FIG. 2, when the tank cover 7 returns to its fixed position, the base member 3 is again covered by the tank cover 7.

In this way, the toilet bowl cleaning device 1 of the present embodiment has the cleaning tank 4 to which cleaning water is supplied, the tank cover 7 that covers the cleaning tank 4, and the tank cover 7 arranged at the normal position and above the normal position. and an operation knob 62 that is arranged inside the tank cover 7 and performs an operation for adjusting the amount of water in the make-up water spouting section 6, which is a functional section. The operating knob portion 62 is covered by the tank cover 7 when the tank cover 7 is in its normal position, and is arranged so as to be operably exposed below the tank cover 7 when the tank cover 7 is in the raised position. Therefore, the operation knob 62 for adjusting the amount of makeup water is covered by the tank cover 7 and is not visible to the user when no operation is required. Therefore, the design of the toilet bowl cleaning device 1 is improved. When operating the operating knob 62, the operating knob 62 can be exposed below the tank cover 7 by raising the tank cover 7, so that the amount of makeup water can be adjusted.

In the toilet flushing device 1 of this embodiment, the operating knob 62 is positioned so that it can be operated laterally of the tank cover 7 when the tank cover 7 is in the raised position. Therefore, an operator who adjusts the amount of make-up water can easily access the operating knob 62 and can operate the operating knob 62 with ease.

The toilet flushing device of this embodiment further includes a base member 3 that supports the lower part of the flushing tank 4 and has a guide wall portion 32 around it, the operation knob portion 62 is disposed inside the guide wall portion 32 of the base member 3, the guide wall portion 32 has an operation opening portion 322 for operating the operation knob portion 62 from outside the base member 3, and the tank cover 7 is configured to cover the base member 3 in a fixed position and to expose the operation opening portion 322 of the guide wall portion 32 of the base member 3 below the tank cover 7 in a raised position. Therefore, the operation knob portion 62 disposed inside the guide wall portion 32 of the base member 3 is exposed to the outside of the base member 3 so as to be operable. Therefore, the operator can easily operate the operation knob portion 62 inside the guide wall portion 32.
