る。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIGS. 1 and 2, a tank mounting portion 2 is provided on the rear upper surface of a toilet 1, and a low tank 3 is mounted on the tank mounting portion 2. A water supply chamber 4 is provided below the tank mounting part 2, and the low tank 3 and the water supply chamber 4 are communicated with each other through a washing water inlet 5 penetrating the bottom of the low tank 3 and the tank mounting part 2. It is. A water passage 7 is provided along the upper end edge of the toilet bowl 6 of the toilet 1, and a large number of injection holes 9 are formed in the bottom of the water passage 7. The water supply chamber 4 and the water passage 7 are communicated with each other through a water supply hole 8. The bottom surface of the water supply chamber 4 is lower than the bottom surface of the water passage 7 so that cleaning water can be stored in the water supply chamber 4 when not being washed. The water supply chamber 4 and the water passage 7 are connected by a water supply hole 8.
Is provided on the bottom surface of the water passage 7, the water supply chamber to the
The water level of 4 only rose slightly,
It becomes difficult for the trapped air to enter the water passage 7. Water supply hole
8 is formed in a sufficient size so that the momentum of the washing water from the low tank 3 does not decrease. Furthermore, the water supply room 4
The washing water inlet 5 provided on the ceiling surface is
Lower position. For this reason, supply water when not washing
The amount of air accumulated in the chamber 4 is reduced. Cleaning water supply
The reason why the mouth 5 is located above the water supply hole 8 is that
So that the washing water in the water supply chamber 4 does not flow back to the raw tank 3
To do that. In order to reduce the accumulation of air in the water supply chamber 4, it is conceivable to make the water supply chamber 4 smaller. However, when the water supply chamber 4 is made smaller, the pressure loss at the time of cleaning is large and the force of the cleaning water from the low tank is reduced. Therefore, the size of the water supply chamber 4 cannot be reduced. Therefore, the washing water is almost completely supplied to the water supply chamber 4.
The air pool is reduced so that it can be fully filled .

される。When the valve 10 of the cleaning water supply port 5 is opened and water is supplied, the cleaning water in the low tank 3 is supplied to the water supply chamber 4 and supplied from the water supply chamber 4 to the water passage 7 through the water supply hole 8. It is injected into the toilet bowl 6 from the injection hole 9 of the water passage 7. At the start of water supply, water is stored in the water supply chamber 4 and almost no air is stored. Therefore, entrainment of air can be reduced and cleaning water can be jetted from the injection holes 9 so that noise is not generated and cleaning power can be increased. When the valve 10 is closed, the water supply is stopped. At this time, the state in which water is stored in the water supply chamber 4 is maintained.

ォン効果を得ることができる。In the above embodiment, a siphon-type flush toilet is described, but a siphon-jet flush toilet can be similarly implemented. In the case of a siphon-jet flush toilet, a strong siphon effect can be obtained by reducing the entrainment of air.

That the water supply hole that connects the pipes is provided on the bottom side of the water channel
If the water level in the water supply chamber when cleaning is not
In addition to making it difficult for air in the water chamber to flow out to the water channel,
Installed on the ceiling surface to guide water from the low tank to the water supply room
Because the flush water inlet is lower than the ceiling of the water channel
In the first place, the amount of air accumulated in the water supply chamber during non-washing
Therefore, the amount of air entrained in the washing water during washing is small, so that noise during washing can be reduced. In addition, since no air is entrained, a strong siphon effect is obtained, and the washing power is improved. , water-saving washing water, also shortening of the cleaning time are those that can Figure Rukoto, yet this
The amount of air that accumulates in the water supply chamber
Despite the above, the washing water inlet is
Is located above, so the low tank is above the water supply chamber.
Reverse to the low tank side
It is difficult for a flow to occur .
