- washing water conduit 16 1 (wash water conduit). For this reason, if the washing water is stored in the ball portion 101, the washing water flows into the washing water storage portion 104 via the jet water outlet 106. Therefore, the washing water storage section 104 has a ball section
- Wash water is stored up to the same height as the water level of 101.
- the inner volume of the washing water storage section 104 is about 2 to 2.5 liters, but the washing water stored in the washing water storage section 104 as described above is about It is about 0.5 liter.
- the amount of water stored in the washing water storage unit 104 is about 14 with respect to the normal 2 liters of stored water in the ball unit 101.

It is configured to switch in chronological order to the connecting pipe 13 7 and the supply pipe 13 3 for pouring washing water into the water flowing rim 103.
- the jet cleaning is performed following the rim cleaning described above, and thereafter, the rim cleaning is performed again.
- the configuration for cleaning the toilet in the toilet 100 of this embodiment and the state of the toilet cleaning will be described.
- the switching valve 41 switches the supply destination of the flush water to the supply pipe 13 3 to which the water flow rim 103 is connected. .
- the washing water that has passed through the water supply valve 105 is guided to the water passing rim 103 via the supply pipe 133, and rim washing is started.
- washing water is discharged along the inner wall surface of the ball portion from the rim water outlet holes 132 provided at appropriate intervals on the lower surface of the water passing rim 103, and the washing water is used to discharge the inner wall surface of the ball portion. Is washed.
- the supply destination of the cleaning water is switched to the connection pipe 1 37 by the switching valve 41. Therefore, the washing water that has passed through the water supply valve 105 is sent to the discharge nozzle 35 via the connecting pipe 135, and is discharged from the discharge nozzle 35. Therefore, jet cleaning starts after rim cleaning, and waste is discharged as follows.
- the discharge nozzle 35 at the end of the connecting pipe 1 37 is disposed in the Z water conduit 161, and is directed substantially in the same direction as the direction of the Z water conduit 16 1. It has been.
- the Z water conduit 16 1 functions as a throat because it serves as a flow path for the water discharged from the discharge nozzle 35 and the wash water in the wash water storage unit 104. Therefore, when the supply destination of the washing water is switched to the connecting pipe 13 37 by the switching valve 41 as described above, the pressure from the discharge nozzle 35 is substantially equal to the pressure on the primary side (water supply pressure of tap water). With high water pressure (about l ⁇ 2 kgf / cm 2 ), washing water flows out at high speed.
- a discharge nozzle 35 for ejecting water supplied from the water supply pipe 2 and a washing water path in front of the discharge nozzle 35 A jet pump is formed by the jet headway 161, which forms ⁇ and guides the washing water to the jet water outlet 106. Therefore, the discharge water of the discharge nozzle 35 is supplied not only to the water in the zigzag channel 161, but also to the washing water storage section 104 which is quickly communicated with the zigzag channel 161. It becomes a jet that involves a large amount of water.
- this jet and the entrained water from the “ ⁇ purified water storage section 104” pass through the jet headway 161 like jet jet by a jet pump, and the jet water from jet water “1” It is discharged directly from 106 to the inlet 1 2 1 of the drain trap 102. Therefore, the maximum width of the washing water is sent to the drain trap 102 at a time.
- the cleaning water actually discharged during the cleaning of the ball portion 101 is from the discharge nozzle 35, but the flow rate cleaning water flows into the ball portion 101. Then, the dirt in the dirt drop recesses 112 is pushed away by the large amount of washing water, strongly pushed into the drain trap 102 1, and discharged from the drain trap 102 described later.
- the jet headway 161 is located at the front of the toilet body 101a.
- the path direction is 180 toward the water discharge port 106. It is rotating, and the radius of curvature of the zigzag part 16 1b is 2 () to 30 mm. The loss due to flow reversal at the zigzag 16 1 b is small.
- the drain trap 102 is provided with an ascending pipe 1 2 2, a descending pipe 1 2 3, and a horizontal pulling path 1 2 4, continuous with the entrance 1 2 1 opened to the waste drop recess 1 1 2 It is configured as a channel.

- the drain trap 102 has a double seal structure that forms a seal at two places in the middle of the drain trap.
- the siphon generation promoting portion 126 for promoting the siphon generation in the drain trap 1.02 is a downpipe. 1 2 3 Formed at the lower end.
- the seal in this case means that the siphon that occurred in the drain trap 102 is not cut off.
- the siphon 3 ⁇ 4 promotion part 126 is designed so that water falling over the weir 1 27 at the upper end of the riser 122 and falling into the descender 123 collides with this water and keep this water as much as possible in the descender 123. I do. Then, the siphon generation promoting portion 126 secures a state in which the drain trap 102 is filled with water by retaining the water, and thereby promotes the generation of the siphon in the drain trap 102. For this reason, the siphon generation promoting portion 126 has a horizontal step portion 126a extending horizontally toward the pipe ⁇ at the lower end of the downcomer pipe 123. The length of the horizontal step portion 126a is 10 to 25 mm (0.18 to 0.45 times the drain trap diameter of 55).

If the horizontal step section 126a is provided at a position above the intersection of the downcomer pipe 123 and the horizontal drawway 124, there are the following disadvantages. First, the flow velocity distribution becomes uneven at the point where the bend connecting the downcomer pipe 1 2 3 and the horizontal pulling path 1 2 4 is bent.
- the water flow bent laterally by the horizontal step portion 126a of the horizontal step becomes a flow blocking the drain trap 102, which may hinder the siphon formation.
- the position of the horizontal step 1 26 a is set lower than the above, the effect of the flow velocity correction will decrease.

Therefore, this umbrella valve 65 functions as a check valve for the flow of the washing water across the bottom wall of the depression 64 as follows. When washing water flows from the left side of the bottom wall of the depression 6 4, that is, from the side of the purified water flow chamber 58 to the side of the depression 64, the communication hole 68 is closed by the umbrella 67. The washing water can only pass through the communication hole 66.
- the washing water passes through the communication hole 66 and pushes up the umbrella part 67 to open the communication hole 68. Also passes. Therefore, the umbrella valve 65 functions as a check valve as described above.

- the valve body 50 since the valve body 50 is in the initial position, the rim port 46 communicates with the inflow port 45 via the flush water inflow chamber 58 as described above (see FIG. 4). Therefore, the washing water flows out to the rim port 46 via the washing water inflow chamber 58. Since the rim port 46 is connected to the supply pipe 13 3, the washing water is guided to the supply pipe 13 3 and discharged from the water passing rim 103, and rim cleaning is started. .

- the pressure receiving area of the wash water pressure in the wash water inflow chamber 58 is defined by the cross-sectional area of the wash water inflow chamber 58, and is equal between the right end valve body 54 and the left end valve body 57. Therefore, the wash water pressure applied to the valve body 50 in the wash water inflow chamber 58 is offset.
- the flush water flowing into the flush water inflow chamber 58 It flows into the second valve chamber 71 through the communication hole 66 in the umbrella valve 65 of FIG.

- the expansion valve chamber 44 where the right end valve body 54 is located and the third valve chamber 72 on the left end valve body 57 side are opened by the communication holes 73 and 74 as described above. Therefore, the valve element 50 receives the above-described valve element driving force generated by the flow of the washing water into the second valve chamber 71 by being piled with the urging force of the spring 59.
- the urging force of the spring 59 is determined by the fact that washing water is not flowing from the inflow port 45, that is, the valve body 50 can be located at the initial position while the valve body 50 is not loaded. Have been able to. For this reason, the valve element 50 receives a valve element driving force that exceeds the urging force of the spring 59 when the washing water flows into the second valve chamber 71, so that the valve element 50 receives the urging force of the spring 59. Move to the left from the initial position in opposition. Then, the movement of the valve element 50 continuously occurs while the washing water flows into the second valve chamber 71.
- the pressure receiving area of the right end valve body 54 in the second valve chamber 71 is reduced by the pressure receiving area in the washing water inflow chamber 58. It is wider than the area. Therefore, in the second valve chamber 71, a high pressure substantially equal to the tap water pressure is applied to the right end valve body portion 54, so that a relatively large valve body driving force can be generated.

- the washing water flows out to the rim boat 46 through the washing water inflow chamber 58, is guided to the supply pipe 133, is discharged from the water passing rim 103, and the rim washing is started again.
- the rim cleaning is performed while the valve body 50 is at the second movement position, that is, immediately over the question that 63 is the rim bottle 46. That is, following the movement of the valve body 50 from the first movement position to the second movement position, the jet port 47 and the rim boat 46 sequentially communicate with the inflow port 45 ', and the jet Switch from cleaning to rim cleaning.
- the rim cleaning for cleaning the inner wall surface of the ball portion and the jet cleaning for discharging dirt from the ball portion have been performed.
- the cleaning water is discharged from the water-flowing rim 103, so that not only the inner wall surface of the ball portion but also the cleaning water can be stored in the ball portion, so-called rim / jet / rim cleaning. It can be performed.
- the valve body 50 When the last rim cleaning is performed for a predetermined time in this manner, specifically, when the water supply valve 105 is closed after a predetermined time has elapsed since the above-described cleaning button was operated, the following is performed. Then, the last rim cleaning is completed, and the valve body 50 returns to the initial position.
- the water supply valve 105 is closed and the cleaning water is no longer supplied to the switching valve 41, the flow of the cleaning water into the second valve chamber 71 is stopped. For this reason, in the second valve chamber 71, the washing water pressure that caused the inflow of the washing water disappears, and the above-described valve body driving force becomes zero.

- the jet energy of the wash water 106 discharged through the discharge nozzle 4 35 from the jet water 106 is expressed as follows: the density of the water is pw, the jet water of the jet is 1-110. If I-i area is S and jet flow velocity is V, it is expressed by the following formula.
- jet energy E expressed by this formula is the one where there is no mixing of air
- the mixing ratio 7 becomes Qii / Qw, where Qa is the air flow: ff £ and Qw is the washing water flow rate.
- the density of the air is Pa
- the washing water density p 'in a state where the air is mixed at a mixing ratio of 7] is the water density pw, the air flow rate Qa, the cleaning water flow rate Qw, and the air flow rate It is expressed as follows using density pa :)
- jet energy P: 'of the cleaning water mixed with air at the above mixing ratio is expressed as follows.
- the flushing The air first mixing into clean water it is possible to increase the (1 + 7?) Only twice washed purification plant absolute Tenerugi E. Therefore, even when the supply of the cleaning water sent to the discharge nozzles 435 is low, the jet discharge is performed with such a high energy, that is, in a state where the flow rate is amplified and the instantaneous flow rate is increased. Cleaning water with increased flow rate can be poured from water inlet 106 toward inlet 1 2 1. Therefore, even with the toilet of the 16th embodiment, it is possible to achieve high washing performance and high water saving irrespective of the level of the water supply pressure, and it is also possible to surely carry out filth transfer and toilet washing.
- This 16th embodiment can be modified as follows. First, similarly to the above-described fifteenth embodiment, the supply pressure of the cleaning water sent to the discharge nozzle 435 is detected by the pressure sensor. If the detected pressure is lower than the pressure P 0 at which high-pressure and high-speed cleaning water discharge is not expected even if the cleaning water is discharged from the discharge nozzle at the same pressure, specifically, the air Mix. In this modified example, only when the washing water supply pressure is low, the pressurizing pump 440 is driven to mix the air, and the washing water can be discharged with high energy. For this reason, the pressurizing pump 440 may be driven intermittently or temporarily to save energy.
- the present invention is useful as a countermeasure for water saving of a toilet bowl which carries out toilet flushing by transporting filth in a bowl portion of the toilet bowl to outside of the toilet bowl using flush water.
