DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Conventionally, in a siphon type toilet, a washing water is jetted toward a trap side from a jet hole formed in a bottom portion of a bowl to activate a siphon in the trap, thereby draining the water. The washing water flows down from the rim at the top of the pot to wash the water, and the washing water is supplied from a low tank or a flush valve to the two water channels of the jet hole and the rim, so that a good siphon is activated at the time of drainage. It is necessary to secure sufficient water pressure and amount of cleaning water to be ejected from the jet holes in order to cause the jetting, but since the cleaning water is also supplied to the rim, the jet water spouting becomes insufficient by this amount, There was a problem that the drainage efficiency deteriorated. Conventionally, a water supply pipe for supplying cleaning water to the rim and the jet hole is thick, and when supplying water from the low tank to the rim and the jet hole, a large amount of cleaning water for supplying water to both the rim and the jet hole. There is a problem that the tank itself must be made large in order to store the wastewater.

[0003]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and it is possible to secure a sufficient water discharge pressure and a water discharge amount of a jet water discharge, and to use a small water storage tank. The gist of the present invention is to provide a flush toilet that jets flush water from the bottom of the bowl toward the trap and a rim spout that flushes flush water from the rim into the bowl. In the above, the jet water discharge path is a water supply direct connection type, and the rim water discharge path is a water supply type from a tank.

[0004]

[Function] The jet water discharge path is directly connected to the water supply,
The jet water can be discharged by securing a sufficient amount of water using the water pressure of the tap water, and since the rim discharge path is a water supply type from the tank, the tank that stores the wash water for rim discharge is small. Any pipe can be used, and a thin pipe is sufficient.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic vertical cross-sectional configuration diagram of a toilet bowl, in which a rim 3 is formed above a pot part 2 for storing water sealing water W in a toilet body 1, and a rim 3 is formed through a rim hole 3 a of the rim 3. Cleaning water can be supplied to the inside. Also,
A trap 4 is formed in the back of the pot 2 in a communicating manner.
The lower end of the trap 4 is a drain 5. Jet holes 6 formed in the bottom of the bowl 2 in the trap 4
, Jet water is ejected from the hopper, the water sealing water W is pushed out toward the trap 4 side by the jet water, and the inside of the trap 4 is filled with water, and the water can be drained from the drain port 5 by a siphon phenomenon.

[0006] A tank 9 is provided upright on the rear upper surface of the toilet body 1 so that the washing water can be stored in the tank 9. A water supply pipe 10 is connected to the bottom surface of the tank 9 of this embodiment, and a valve 11 is provided in the water supply pipe 10 so as to be openable and closable. The water supply pipe 10 is a rim water passage formed on the inner periphery of the rim 3. It has been communicated inside. In this embodiment, a jet water supply pipe 7 is connected to the jet hole 6, and a valve 8 is provided in the jet water supply pipe 7 so as to be openable and closable, and the jet water supply pipe 7 is directly connected to a water pipe. It has been done.

In such a structure, when the user turns on a switch (not shown) or the like during cleaning, the valve 8 and the valve 11 are opened, and tap water flows from the jet hole 6 to the trap 4 as jet water. At the same time, the washing water in the tank 9 flows down from the rim hole 3a of the rim 3 toward the pot 2 so that the inside of the pot 2 is washed.

In the present embodiment, the washing water jetted from the jet hole 6 is directly connected to the tap water, so that a sufficient amount of water and a sufficient water pressure can be ensured. A large amount of washing water can be satisfactorily spouted into the trap 4 without lowering the water supply amount, so that the siphon can be started satisfactorily and drainage efficiency can be reliably increased.
In addition, only the washing water for rim washing needs to be stored in the tank 9, and a small capacity of the tank 9 is sufficient, so that the entire toilet can be made smaller. In addition, it is sufficient that the diameter of the water supply pipes 7 and 10 is smaller than in the related art. Water is supplied to the tank 9 from a water pipe. However, when jet water is jetted from the jet hole 6, it is possible to control the supply of water into the tank 9 using an electromagnetic valve or the like so as to shut off the water supply. it can.

[0009]

According to the present invention, in a toilet bowl which performs jet spouting for jetting washing water from the bottom of the pot to the trap side and rim spouting for jetting washing water down from the rim into the pot, the jet spouting path is directly connected to a tap. And the rim spouting path is a water supply type from a tank, the jet spouting flush water can use the water supply pressure of the water pipe directly and effectively, ensuring a sufficient amount of water and water pressure. The drainage function can be satisfactorily exhibited, and the amount of washing water supplied into the rim water discharge path can be reduced to a small amount.
