Abstract

PURPOSE:To increase the washing effect of a stool face, by washing the toilet bowl by delivering water from rims after a delayed time interval until the water level goes down after the flushing water is ejected from jet holes. CONSTITUTION:A user pushes on the washing button to drive the first piston and eject jet water from jet holes 6 toward the trap 4 side to fill water in the trap 4. Next, a siphon phenomenon occurs and the washing water is discharged from discharge outlet 5 to the drain pipe by the siphon action. When discharging the level of the sealed water goes down to the lowerend position of the bowl 2 and then the second piston starts. Next, the washing water flows down from the rim 3 into the bowl 2. This down-flow water reaches the lowerend level of the bowl 2 to clean well the whole face of the bowl 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a toilet bowl cleaning method.

[0002]

2. Description of the Related Art Conventionally, in a siphon-type toilet bowl, a jet spout for jetting jet water from a jet hole to a trap side and a bowl washing for spouting flush water from a rim above the bowl to wash the bowl Since water is spouted at the same time, and in such a washing method, the bowl is spouted when the water level of the water-sealing water on the pot is high, so the bottom of the pot where the water-sealing water is present is well washed. However, there is a problem in that a sufficient cleaning effect on the pot surface cannot be obtained.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned problems of the prior art, and an object thereof is not to provide a toilet bowl cleaning method capable of enhancing the effect of cleaning a bowl surface. The gist is a jet water spouting jetted to the trap side for draining the water sealing water in the bowl, and a bowl cleaning water spouting method in which the water is spouted into the bowl from above the water sealing water surface. After the water spouting, the bowl cleaning water spouting is performed with a time lag until the water sealing surface is lowered.

[0004]

[Function] The jet water is discharged to the trap side, and the water level of the water seal water in the bowl lowers. At this time, the bowl wash water is discharged, and the bottom edge of the bowl surface is discharged by the bowl water wash. Can be washed well up to.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a cross-sectional configuration diagram of the toilet body, in which the bowl 2 of the toilet body 1 always stores water-sealing water W, a rim 3 is formed above the bowl 2, and a rim 3 is formed behind the bowl 2. A trap 4 is formed in a communicating manner, a lower end portion of the trap 4 is an outlet hole 5 communicating with a drain pipe (not shown), and a jet hole 6 for jetting jet water is formed under the pot 2. .

In such a toilet bowl, in this embodiment, jet water is jetted from the jet hole 6 toward the trap 4 and bowl washing is made to flow down the wash water from the rim 3 or the like toward the bowl 2 surface. The water discharge is configured so that the water is discharged at a different timing, for example, as shown in FIG.
The flush valve structure as shown in the schematic diagram is adopted, and when the user turns on the cleaning push button 10, the first piston 11 is activated, and the activation of the first piston causes the jet hole 6 to be ejected. Jet water is ejected, the second piston 12 is activated a little later than the activation of the first piston 11, and the flushing water is discharged from the rim 3 and the like by the activation of the second piston. The flush valve is the first piston 11
Is configured so that the second piston 12 is closed at a different timing after the second piston 12 is closed.

When the flush valve having such a structure is operated, jet water is jetted from the jet hole 6 toward the trap 4 side by the activation of the first piston 11, as shown in FIG. When the water fills up, siphon activation occurs, and due to the siphon phenomenon, washing water is discharged through the outlet hole 5
Is drained to a drain pipe (not shown). During the drainage, the water surface of the water sealing water W goes down and the water surface goes down to the lower end of the bowl 2. In this state, the second piston 12 is activated as shown in FIG. The washing water is made to flow down into the bowl 2, and the washing water flowing down reaches the lower end of the surface of the bowl 2. Therefore, the entire area of the surface of the bowl 2 can be washed well, and the lower end of the bowl 2 is washed as in the conventional case. It is possible to satisfactorily eliminate the situation in which it is not possible to improve the cleaning effect on the two surfaces of the pot.

In this embodiment, the flush valve using two pistons is illustrated, but a switching valve is provided in the water channel system of the wash water, and the jet ejected from the jet hole 6 through this switching valve. It is also possible to switch the water discharge path and the water path for the bowl cleaning water discharge from the rim 3 or the like to shift the timings of jet water discharge and bowl cleaning water discharge.

[0009]

INDUSTRIAL APPLICABILITY The present invention relates to a toilet bowl for jetting water jetted to the trap side in order to drain the water-sealed water in the bowl and for flushing the bowl to spout water in the bowl from above the water-sealed surface. In the cleaning method, after the jet water spouting, since it was decided to perform the bowl cleaning water spouting with a delay until the water sealing water surface lowers, the bowl cleaning water spouting is performed in a state where the water sealing water surface is lowered by the jet water spouting, so the bowl It is possible to satisfactorily wash the lower end portion of the bowl surface by washing water, and improve the washing effect of the bowl surface.
