<Means to increase waste discharge efficiency>
On the bowl surface 21, a swirling guide surface 30 is formed as means for increasing the flow velocity (swirl peripheral speed) of the swirling water WR in the swirling flow generator 20. As shown in FIGS. 1 and 3, in a plan view, the swivel guide surface 30 is continuously formed from the vicinity of the outer peripheral edge of the bowl surface 21 to the vicinity of the opening edge 20 </ b> Y of the swirl flow generator 20, and the swirl flow generator It extends in a position and an orientation that are generally tangential to the 20 opening edges 20Y. Further, the turning guiding surface 30 is curved so as to swell in the counterclockwise direction (that is, the same direction as the turning direction of the washing water in the bowl surface 21).

  In the circumferential direction about the swirl flow generating unit 20, the position of the inner peripheral end of the swivel guide surface 30 is shifted in the counterclockwise direction from the outer peripheral end of the swivel guide surface 30. Is arranged. And as shown in FIG. 3, the edge part of the outer peripheral side of the guidance surface 30 for rotation is shifted in the counterclockwise direction from the first water outlet 18R, and is shifted in the clockwise direction from the second water outlet 18L. In other words, it is arranged at a position behind the swirl flow generator 20. The inner peripheral end of the turning guide surface 30 is arranged so as to merge from the diagonally left rear direction to the diagonally right front direction with respect to the region extending from the left side edge to the front edge of the opening edge 20Y of the rotational flow generation unit 20. Has been.

  As shown in FIG. 6, the turning guide surface 30 has a shape that rises in a step shape from the bowl surface 21 at an angle α that is close to the vertical direction. As shown in FIGS. 1 and 3, in a plan view, a region of the bowl surface 21 that is clockwise from the turning guide surface 30 (a region upstream of the washing water turning direction on the bowl surface 21) is for turning. Compared to the region in the counterclockwise direction from the guide surface 30 (the region on the bowl surface 21 on the downstream side in the swirling direction of the washing water), the height is stepwise lower. The swiveling guide surface 30 exhibits a function of guiding the cleaning water swirling along the bowl surface 21 into the swirling flow generating unit 20 while applying a swirling force. Even if the flow rate of the wash water to be discharged is low, a sufficient swirl force can be applied to the swirl flow WR in the swirl flow generation unit 20 by the swirl guiding surface 30.

  In addition, a drop guiding surface 31 is formed on the bowl surface 21 as means for applying a downward (drainage 23 side) pushing force to the swirling flow WR in the swirling flow generating unit 20. As shown in FIGS. 1 and 3, the drop guiding surface 31 is formed continuously from the vicinity of the outer peripheral edge of the bowl surface 21 to the vicinity of the opening edge 20 </ b> Y of the swirling flow generating unit 20, similar to the turning guiding surface 30. Yes.

  As shown in FIG. 3, in plan view, the outer peripheral end of the drop guide surface 31 is shifted in the clockwise direction from the first water discharge port 18 </ b> R, that is, to the right of the swirl flow generating unit 20. Placed in position. An end portion on the inner peripheral side of the drop guide surface 31 is positioned so as to abut against a region where the right edge and the rear edge of the opening edge 20 </ b> Y of the swirl flow generator 20 are continuous. In other words, the drop guide surface 31 is substantially linear along the radial direction about the swirl flow generation unit 20, and extends so as to intersect the opening edge 20 </ b> Y of the swirl flow generation unit 20.

  As shown in FIG. 5, the drop guide surface 31 has a shape that rises in a step shape from the bowl surface 21 at an angle β close to the vertical direction. As shown in FIGS. 1 and 3, in a plan view, a region in the clockwise direction of the drop surface 21 of the bowl surface 21 (a region upstream of the swirling direction of the washing water on the bowl surface 21) is for dropping. Compared to the region in the counterclockwise direction from the guide surface 31 (the region on the bowl surface 21 on the downstream side in the swirling direction of the washing water), the height is stepwise lower.

  As shown in FIGS. 5 and 6, the rising angle β of the drop guiding surface 31 with respect to the horizontal plane is set to be slightly larger than the rising angle α of the turning guiding surface 30 with respect to the horizontal plane. Moreover, as shown in FIGS. 7 and 8, the adjacent region 31 </ b> N shifted from the drop guide surface 31 in the clockwise direction (the upstream side of the swirling flows WA and WB on the bowl surface 21) of the bowl surface 21 is the bowl surface. It inclines so that it may descend | fall toward the turning flow production | generation part 20 from the outer periphery of 21. FIG. Further, an adjacent region 30N of the bowl surface 21 that is shifted in the clockwise direction from the turning guide surface 30 is also inclined so as to descend from the outer peripheral edge of the bowl surface 21 toward the turning flow generation unit 20. The inclination angle γ of the adjacent area 31N of the drop guiding surface 31 with respect to the horizontal plane is set to be larger than the inclination angle δ of the adjacent area 30N of the turning guiding surface 30 with respect to the horizontal plane. Note that the inclination angles γ and δ of these adjacent regions 30N and 31N are angles formed between a straight line connecting the outer peripheral end of each region and the opening edge 20Y of the swirling flow generating unit 20 and a horizontal plane.

<Action and effect>
When cleaning the inside of the pot 10, a predetermined amount of cleaning water is supplied from the water supply port 14 to the rim water passage 15. The supplied wash water passes through the first flow path 17R and the second flow path 17L, and is discharged from the first water discharge port 18R and the second water discharge port 18L to the pot surface 21. Most of the wash water discharged from the first water discharge port 18R swirls in the counterclockwise direction in the area behind the swirling flow generating unit 20 in the bowl surface 21, as indicated by the arrow WA in FIG. The dirt is removed from the bowl surface 21 while colliding with the turning guide surface 30. The washing water and the filth that have come into contact with the swivel guide surface 30 have a swirl flow generator 20 due to the spirally curved shape of the swivel guide surface 30 and the inclination of the adjacent region 30N of the swivel guide surface 30 in plan view. And the counterclockwise swirl flow WR is generated in the swirl flow generator 20.

  Most of the washing water discharged from the second water discharge port 18L is from the swirl flow generating unit 20 and the region on the left front side of the swirling flow generating unit 20 and the swirling flow generating unit 20 as indicated by an arrow WB in FIG. In addition, while turning in the counterclockwise direction so as to sequentially pass through the front area and the area on the right front side of the swirl flow generation unit 20, dirt is removed from the bowl surface 21 and collides with the drop guide surface 31. The washing water and the filth that hit the drop guiding surface 31 are guided into the swirling flow generating unit 20 along the dropping guiding surface 31 due to the inclination of the adjacent region 31N of the dropping guiding surface 31, and an arrow line in FIG. As shown by WF, it falls at an angle close to the vertical direction.

  In addition, a part of the wash water discharged from the first water discharge port 18R passes the outer peripheral side from the turning guide surface 30 and passes over the turning guide surface 30 to be washed from the second water discharge port 18L. Merges with water (swirl WB). In addition, a part of the cleaning water discharged from the second water discharge port 18L passes the outer peripheral side of the drop guide surface 31 and gets over the drop guide surface, and the wash water discharged from the first water discharge port 18R ( It merges with the swirl flow WA).

  In the swirl flow generating unit 20, the cleaning water and the filth that flowed in while being guided from the bowl surface 21 to the swivel guiding surface 30 swirl while entraining the stored water Ws of the water seal unit 26. The swirling flow WR is pushed out from the lower end of the swirling flow generating unit 20 to the drainage channel 23 side and discharged by the downward force of the washing water flowing into the swirling flow generating unit 20 from the bowl surface 21. The discharge efficiency of filth becomes higher as the pushing force from the swirling flow generator 20 to the drainage channel 23 becomes stronger. In order to increase the pushing force to the drainage channel 23, it is effective to increase the momentum of the washing water falling from the bowl surface 21 into the swirling flow generating unit 20.

  Therefore, in the present embodiment, as means for increasing the discharge efficiency of the filth, it rises in a step shape from the bowl surface 21 and drops in a form extending in a direction intersecting the opening edge 20Y of the swirl flow generating unit 20 in plan view. A guide surface 31 was formed. The drop guiding surface 31 exhibits a function of guiding the cleaning water swirling along the bowl surface 21 to forcibly fall into the swirling flow generating unit 20. Therefore, the washing water (swirl flow WB) swirling on the bowl surface 21 is forced into the swirl flow generator 20 by the momentum of the drop of the wash water that is forcibly guided to the swirl flow generator 20 by the drop guide surface 31. Be drawn into.

  As shown in FIG. 3, the direction of the cleaning water flux WF guided to the drop guide surface 31 is a direction intersecting the opening edge 20 </ b> Y of the swirling flow generating unit 20 in a plan view. Therefore, the swirl force of the washing water guided to the drop guide surface 31 is kept small, and the momentum in the drop direction is increased accordingly. Moreover, the rising angle β of the drop guiding surface 31 with respect to the horizontal plane is set to a relatively large angle (an angle larger than the rising angle α of the turning guiding surface 30 with respect to the horizontal plane). The inclination angle γ of the adjacent area 31N of the guiding surface 31 with respect to the horizontal plane is also set to a relatively large angle (an angle larger than the inclination angle δ of the bowl surface 21 with respect to the horizontal plane of the adjacent area 30N of the turning guiding surface 30). Yes. Therefore, the action of drawing the wash water into the swirl flow generator 20 is more powerful. Thereby, even if the flow rate of the washing water swirling on the bowl surface 21 is high, the washing water can be effectively drawn into the swirling flow generating unit 20 to increase the waste discharge efficiency.

  Further, in the swirling flow generating unit 20, as shown in FIGS. 4 and 8, the direction of the flow WF of the washing water falling by the dropping guiding surface 31 is substantially vertical, whereas the swirling guiding surface is The flux of the washing water (swirl flow WR) guided into the swirl flow generator 20 by 30 tends to swirl substantially along a horizontal plane. Therefore, the cleaning water flux WF that has fallen in the swirl flow generation unit 20 by the guidance of the drop guide surface 31 and the wash water that has been induced in the swirl flow generation unit 20 by the guidance of the swivel guide surface 30 are generated. The swirl flow WR collides so as to be substantially orthogonal. According to this configuration, the direction of the flux of the swirling flow WR is changed so as to be inclined with respect to the horizontal by the falling wash water, so that the swirling flow WR in the swirling flow generating unit 20 is directed to the drainage channel 23 side. It becomes easy to move. Thereby, discharge efficiency increases.
