Japanese Patent No. 5959055

  In the toilet body of Patent Document 1, in order to create the flow as described above, a first water outlet and a second water outlet for discharging washing water are formed at appropriate positions in the toilet bowl. Specifically, the 1st water outlet is formed in the front-end | tip of the channel-shaped 1st water supply chamber formed in the upper left periphery of the toilet bowl part. The 2nd water outlet is formed in the front-end | tip of the 2nd water supply chamber of the channel | path shape formed in the upper periphery of the right side of a toilet bowl part. However, in the toilet body of Patent Document 1, when the first water outlet and the second water outlet are formed in the toilet bowl, the configuration in the toilet bowl is complicated, and the shape of the toilet body is restricted. .

  The present invention has been made in view of the above-described conventional situation, and it is a problem to be solved to provide a toilet that can supply flush water with an appropriate flow rate to a desired portion of a toilet bowl with a simple configuration. It is said.

The toilet of the present invention is
Toilet bowl,
A spout formed by adjoining a plurality of water discharge portions with different flow rates of water to be discharged into the toilet bowl,
It is characterized by providing.

  This toilet includes a water outlet having a plurality of water discharge portions having different flow rates of water for discharging water to the toilet bowl. Therefore, the toilet bowl can supply the washing water with an appropriate flow rate to a desired portion in the toilet bowl. In particular, since the toilet bowl is formed with a plurality of water discharge portions adjacent to each other, the flush water can be discharged with a simple configuration.

It is a perspective view which shows the toilet bowl of Example 1. FIG. It is a longitudinal cross-sectional view of the toilet of FIG. It is a longitudinal cross-sectional view of the toilet bowl which concerns on Example 2. FIG. It is a longitudinal cross-sectional view of the toilet bowl which concerns on Example 3. FIG. It is a top view which shows the flow of the washing water in the toilet bowl of FIG. It is a longitudinal cross-sectional view of the toilet bowl which concerns on Example 4. FIG.

  A preferred embodiment of the present invention will be described.

The spout of the toilet of the present invention is
A first water discharger for discharging wash water to the toilet bowl,
A second water discharger for discharging washing water having a flow rate greater than that of the first water discharger to the toilet bowl;
Can have.
In this case, this toilet supplies the wash water by the first water discharger to the portion where the wash water is to be supplied in a relatively small amount in the toilet bowl, and the second portion is supplied to the portion in which the wash water is to be supplied relatively relatively. Wash water can be supplied by the water discharger. For example, the toilet bowl can wash | clean the surface of a stool part favorably by generating a swirling flow by flowing wash water along the upper edge part of a stool part by a 1st water discharging part. On the other hand, the toilet bowl has a strong momentum by discharging the washing water having a larger flow rate than the first water discharging part to the toilet bowl part by the second water discharging part, and flowing the washing water in the discharge direction of the filth. The filth can be discharged well with the flow of

The second water discharge portion of the toilet of the present invention may have an opening area per predetermined length in the horizontal direction larger than an opening area per predetermined length in the horizontal direction of the first water discharge portion.
In this case, in this toilet, the flow rate of the washing water supplied to the toilet bowl portion varies depending on the size of the opening area in the opening portion of each water discharge portion. Therefore, a toilet changes the opening area of each opening part by changing the opening shape of a 1st water discharging part and a 2nd water discharging part, and prescribes | regulates the flow volume of the wash water supplied to a toilet bowl part from each water discharging part. Can do.

The toilet bowl portion of the toilet of the present invention includes a reservoir portion in which washing water stays in the lower portion,
The first water discharge part flows flush water along the upper edge of the toilet bowl,
The second water discharger can flow wash water toward the water reservoir.
In this case, since this toilet flushes the flush water along the upper edge of the toilet bowl by the second water discharger, the flush water flows down while turning around the surface of the toilet bowl. Therefore, the toilet bowl can wash | clean the surface of a toilet bowl part favorably with the washing water of a small flow volume. On the other hand, since the toilet flushes the wash water toward the water reservoir by the first water discharger, the momentum of the wash water flowing downward toward the water reservoir can be increased. Therefore, the toilet bowl can discharge filth from the toilet bowl through the water reservoir.

The first water discharge portion of the toilet of the present invention may be located farther than the second water discharge portion with respect to a center line passing through the center in the left-right direction when viewed from the tip of the toilet bowl at the water discharge port. .
In this case, since the first water discharger is located farther than the second water discharger with respect to the center line passing through the center in the left-right direction when viewed from the front end of the toilet bowl, 2 The water is more distant from the water reservoir than the water discharger, and the wash water can easily turn around the surface of the toilet bowl. On the other hand, since the 2nd water discharging part is located near the 1st water discharging part near the center line in the water outlet, the toilet bowl is closer to the water collecting part than the first water discharging part. It becomes easy to strengthen the momentum of the washing water flowing downward.

The toilet bowl portion of the toilet of the present invention is made of ceramics,
The spout may be formed at the upper edge of the toilet bowl.
In this case, this toilet can form a spout with a different opening area in the toilet bowl, and can discharge flush water of a desired flow rate to the toilet bowl.

The toilet of the present invention is
Provided with a lead-out path for leading wash water to the toilet bowl,
The toilet bowl is formed with an opening connected to the inside,
The lead-out path has a lead-out port that discharges wash water to the toilet bowl through the opening,
The water outlet may be the outlet.
In this case, in this toilet, the flow rate of the wash water discharged for each part of the toilet bowl is defined by the shape of the outlet of the outlet path. Therefore, regardless of the shape of the opening formed in the toilet bowl, the flush water of a desired flow rate can be discharged to the toilet bowl through the outlet of the outlet path.

  Next, an embodiment embodying the toilet of the present invention will be described with reference to the drawings.

<Example 1>
The toilet bowl 10 of Example 1 is comprised as a flush toilet bowl.

  The toilet bowl 20 has a bowl shape with an upper end opened in a substantially elliptical shape. The toilet bowl portion 20 includes a first standing wall portion (corresponding to an “upper edge portion” in the claims) 21, an inclined wall portion 22, and a second standing wall portion 23. The 1st standing wall part 21 hangs substantially perpendicularly from the inner peripheral part of the rim | limb part 12 mentioned later. The inclined wall portion 22 is inclined obliquely downward from the lower end of the first standing wall portion 21 toward the water storage portion 24. As will be described later, the inclined wall portion 22 is formed with a water discharge port 30 through which washing water is discharged. The second standing wall portion 23 hangs substantially vertically from the lower end of the inclined wall portion 22. The drain pipe 16 communicates with the second standing wall portion 23.

  The drain pipe 16 includes a first descending channel 16A, an ascending channel (not shown), and a second descending channel (not shown). The first descending flow path 16A is continuous with the downstream end of the second standing wall portion 23 and extends rearward and downward. The ascending channel is continuous with the downstream end of the first descending channel 16A and extends rearward and upward. The second descending flow path extends rearward and downward continuously from the downstream end of the ascending flow path.

  The toilet bowl part 20 comprises the water storage part 24 by the lower end part of the 2nd standing wall part 23, and the upper end part of 16 A of 1st downward flow paths. In the reservoir 24, the wash water flowing down along the inclined wall portion 22 and the second standing wall portion 23 is retained.

  The rim portion 12 is provided continuously on the outer periphery of the upper end of the toilet bowl portion 20. The rear end of the rim portion 12 is continuous with the upper wall portion 14. The upper wall portion 14 is a wall formed so as to be substantially horizontal. Behind the upper wall portion 14, a tank mounting portion 15 on which a cleaning tank (not shown) is mounted is provided. A toilet seat (not shown) is placed on the upper surface of the rim portion 12.

  The peripheral wall 13 covers the toilet bowl 20 from the front side to the left and right side surfaces. The peripheral wall 13 accommodates a drain pipe 16 and the like disposed below the toilet bowl 20 inside. The peripheral wall portion 13 hangs from the outer peripheral edge portion of the rim portion 12.

  The lead-out path 40 leads the wash water discharged from the wash tank to the toilet bowl 20. As shown in FIG. 1, the lead-out path 40 is disposed on the rear side of the toilet bowl 20. The lead-out path 40 includes an inflow portion 41 and a lead-out pipe 42. The inflow portion 41 is inserted with a drain port of a cleaning tank (not shown) that is placed and fixed on the tank placement portion 15. The lead-out pipe 42 communicates with the inflow portion 41 and guides wash water flowing from the inflow portion 41 to the toilet bowl 20. The outlet tube 42 has a outlet port 43 that discharges flush water to the toilet bowl 20 at the tip.

  Next, the water outlet 30 formed in the toilet bowl 20 will be described. As shown in FIGS. 1 and 2, the toilet bowl 20 has a spout 30 formed therein. The water discharge port 30 is a through-hole penetrating the first standing wall portion 21 in the wall thickness direction. The water outlet 30 is formed in a substantially inverted L shape. The spout 30 is formed on the rear end side of the toilet bowl 20 at a position closer to the left side than the center in the width direction (left-right direction) of the toilet bowl 20. The outlet 30 is provided with a lead-out pipe 42 at the rear, and faces the lead-out opening 43. The spout 30 discharges the wash water led out by the lead-out path 40 to the inside of the toilet bowl 20.

  As shown in FIGS. 1 and 2, the water discharge port 30 includes a first water discharge unit 31 and a second water discharge unit 32. The water discharge port 30 discharges wash water to the inside of the toilet bowl 20 by the first water discharge unit 31 and the second water discharge unit 32. The water discharge port 30 is formed adjacent to each other so that the first water discharge unit 31 and the second water discharge unit 32 are continuous. As shown in FIG. 2, the first water discharge portion 31 is formed by cutting out a substantially trapezoidal (trapezoidal shape with rounded corners) region A1 in the first standing wall portion 21. The second water discharger 32 is formed by cutting out a substantially rectangular region (rectangular shape with rounded corners) adjacent to the region A1 in the first standing wall portion 21. As for the 2nd water discharging part 32, the opening part has extended upwards rather than the 1st water discharging part 31, and the opening area is correspondingly larger than the 1st water discharging part 31.

  As shown in FIG. 2, the first water discharger 31 has an opening area S1 per predetermined length (L1) in the horizontal direction. As for the 2nd water discharging part 32, the opening area per predetermined length (L1) of a horizontal direction is S2. The opening area S2 of the second water discharger 32 is larger than the opening area S1 of the first water discharger 31. The first water discharger 31 and the second water discharger 32 wash the flow rate according to the opening area by deriving a constant amount of wash water (for example, a flow rate at which the lead-out pipe 42 is full) by the lead-out path 40. Water is discharged into the toilet bowl 20. Since the opening area S <b> 2 is larger than the opening area S <b> 1 of the first water discharge part 31, the second water discharge part 32 discharges wash water having a flow rate larger than that of the first water discharge part 31 to the toilet bowl part 20.

  As shown in FIGS. 1 and 2, the first water discharger 31 is located at the water discharge port 30 on the side far from the center line C passing through the center in the left-right direction when viewed from the tip of the toilet bowl 20. The first water discharger 31 is formed at a position close to the left end of the toilet bowl 20 (the left part of the first standing wall 21) on the rear end side of the toilet bowl 20. The first water discharge portion 31 is formed near the upper end portion of the inclined wall portion 22. The first water discharger 31 opens toward the direction along the left end of the toilet bowl 20 (the left part of the first standing wall 21). The first water discharger 31 causes the cleaning water to flow on the inclined wall portion 22 along the left side portion of the first standing wall portion 21.

  The 2nd water discharging part 32 is located in the side near the centerline C in the water discharging port 30, as shown to FIG. 1, FIG. The second water discharger 32 is located closer to the reservoir 24 than the first water discharger 31 in the left-right direction on the rear end side of the toilet bowl 20. The second water discharger 32 opens toward the water reservoir 24. The second water discharger 32 causes the cleaning water to flow on the second standing wall 23 toward the water reservoir 24.

  When the toilet 10 configured as described above drains the wash water stored in the wash tank (not shown) from the drain and performs toilet cleaning, the wash water is discharged from the spout 30 via the outlet 40. Is done. The wash water discharged from the water discharge port 30 is mainly the flow of the wash water discharged from the first water discharge unit 31 (flow F1 shown in FIG. 1) and the wash water discharged mainly from the second water discharge unit 32. A flow (flow F2 shown in FIG. 1) is created. The flow F <b> 1 is formed by the wash water discharged from the first water discharge portion 31 mainly flowing along the first standing wall portion 21 on the inclined wall portion 22. The flow F1 flows down while swirling on the inner surface of the toilet bowl 20 (the surface of the inclined wall portion 22). Even if the flow F <b> 1 is formed with a small amount of wash water discharged from the first water discharge unit 31, the wash water can be reliably flowed over the entire inner surface of the toilet bowl 20. In the toilet bowl 10, the wash water flows while swirling on the inner surface of the toilet bowl 20 by the flow F <b> 1, and thus the wash water can flow for a long time along the surface of the toilet bowl 20. For this reason, the toilet bowl 10 can wash | clean the surface inside the toilet bowl part 20 favorably.

  The flow F <b> 2 is formed mainly by the wash water discharged from the second water discharge part 32 flowing on the inclined wall part 22 and the second standing wall part 23 toward the water storage part 24. The flow F <b> 2 flows down the inner surface of the toilet bowl 20 (the surfaces of the inclined wall portion 22 and the second standing wall portion 23) toward the water reservoir 24. Further, the second water discharger 32 discharges cleaning water having a flow rate larger than that of the first water discharger 31. For this reason, the flow F2 has a stronger momentum of the cleaning water flowing downward toward the water reservoir 24. Since this strong flow F <b> 2 is directed to the drain pipe 16 via the water reservoir 24, filth can be discharged well from the toilet bowl 20.

  As described above, the water discharge port 30 is formed so that a part of the opening shape becomes larger upward by making the second water discharge portion 32 larger than the first water discharge portion 31. Thereby, the toilet bowl 10 is producing the desired flow (flow F1 and flow F2) of the wash water efficiently. Thus, the toilet bowl 10 does not need to devise the shape of the toilet bowl 20 or to form a plurality of spouts as in the prior art in order to create a desired flow of washing water. Constraints such as the shape can be reduced. Therefore, the toilet bowl 10 can improve the appearance of the toilet bowl part 20, and can reduce manufacturing cost.

Hereinafter, the effect of this configuration will be exemplified.
The toilet bowl 10 of Example 1 is provided with the water outlet 30 which has the some water discharging part (the 1st water discharging part 31 and the 2nd water discharging part 32) from which the flow volume of the washing water discharged to the toilet bowl part 20 differs. For this reason, the toilet 10 can supply cleaning water with an appropriate flow rate to a desired portion of the toilet bowl 20. In particular, since the first water discharger 31 and the second water discharger 32 are formed adjacent to each other in the toilet bowl 10, the flushing water can be discharged with a simple configuration in which only one water discharge port 30 is formed in the toilet bowl 20. It can be performed.

  The water discharge port 30 of the toilet bowl 10 includes a first water discharge unit 31 that discharges wash water to the toilet bowl 20 and a second water discharge unit 32 that discharges wash water having a flow rate higher than that of the first water discharge unit 31 to the toilet bowl 20. And having. For this reason, the toilet 10 supplies the wash water by the first water discharger 31 to the portion in the toilet bowl 20 where the wash water is to be supplied in a relatively small amount, and the part in which the wash water is to be supplied in a relatively large amount Wash water can be supplied by the second water discharger 32. For example, the toilet 10 causes the swirling flow to flow well along the first standing wall portion 21 of the toilet bowl 20 by the first water discharger 31, so that the surface of the toilet bowl 20 is washed well. Can do. On the other hand, the toilet bowl 10 spouts wash water having a flow rate larger than that of the first water discharge section 31 to the toilet bowl 20 by the second water discharge section 32, and causes the wash water to flow toward the discharge direction of filth. Soil can be discharged well with a flow of washing water.

  The opening area per predetermined length in the horizontal direction of the second water discharge part 32 of the toilet 10 is larger than the opening area per predetermined length in the horizontal direction of the first water discharge part 31. For this reason, as for the toilet bowl 10, the flow volume of the wash water supplied to the toilet bowl part 20 changes with the magnitude | size of the opening area in the opening part of each water discharging part. Therefore, the toilet 10 changes the opening area of each opening part by changing the opening shape of the 1st water discharging part 31 and the 2nd water discharging part 32, and the flow volume of the wash water supplied to the toilet bowl part 20 from each water discharging part Can be defined.

  The toilet bowl part 20 of the toilet bowl 10 includes a water storage part 24 in which washing water stays in the lower part. The first water discharger 31 allows flush water to flow along the first standing wall 21 of the toilet bowl 20. The second water discharger 32 allows the cleaning water to flow toward the water reservoir 24. For this reason, since the toilet 10 flows the wash water along the first standing wall portion 21 of the toilet bowl 20 by the second water discharger 32, the wash water flows down while turning around the surface of the toilet bowl 20. Therefore, the toilet bowl 10 can wash | clean the surface of the toilet bowl part 20 favorably with the washing water of a small flow volume. On the other hand, since the toilet 10 flows the wash water toward the reservoir 24 by the first water discharger 31, the momentum of the wash water flowing downward toward the reservoir 24 can be increased. Therefore, the toilet bowl 10 can discharge the filth from the toilet bowl 20 through the reservoir 24.

  The first water discharge portion 31 of the toilet 10 is located farther than the second water discharge portion 32 with respect to the center line C passing through the center in the left-right direction when viewed from the tip of the toilet bowl 20 at the water discharge port 30. For this reason, in the toilet 10, the first water discharger 31 is farther than the second water discharger 32 with respect to the center line C passing through the center in the left-right direction when viewed from the tip of the toilet bowl 20 at the water discharge port 30. Since it is located, it is further away from the water reservoir 24 than the second water discharger 32, and the wash water can easily turn around the surface of the toilet bowl 20. On the other hand, in the toilet bowl 10, the second water discharge part 32 is located closer to the center line C than the first water discharge part 31 at the water discharge port 30, so that the water reservoir 24 is more than the first water discharge part 31. It becomes easy to strengthen the momentum of the wash water that flows downward toward the reservoir 24.

  The toilet bowl 20 of the toilet bowl 10 is made of earthenware. The spout 30 is formed in the first standing wall portion 21 of the toilet bowl 20. For this reason, the toilet bowl 10 can form the spout 30 in which the opening area differs in the toilet bowl part 20, and can discharge the wash water of a desired flow volume to the toilet bowl part 20. FIG.

<Example 2>
Next, Example 2 will be described.
The toilet 10 of the second embodiment is different from the first embodiment in that a desired flow of washing water is created by the outlet 60 instead of the water outlet 30. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  The water discharge port (corresponding to “opening” in the claims) 50 of Example 2 is formed in a substantially rectangular shape as shown in FIG. 3. The spout 50 is formed on the rear end side of the toilet bowl 20 at a position closer to the left side than the center in the width direction (left-right direction) of the toilet bowl 20. The outlet 50 is provided with a outlet pipe 42 at the rear, and faces the outlet 60.

  As shown in FIG. 3, the outlet 60 (corresponding to the “water outlet” in the claims) 60 has a substantially inverted L shape. The outlet 60 includes a first outlet 61 and a second outlet 62. In the outlet 60, the first outlet 61 and the second outlet 62 lead the wash water to the toilet bowl 20 through the water outlet 50. The outlets 60 are formed adjacent to each other so that the first outlet 61 and the second outlet 62 are continuous. The first lead-out portion 61 is formed so as to cover a part (a portion excluding the right end portion) of a substantially trapezoidal (trapezoidal shape with rounded corners) region A3 when viewed from the front-rear direction. The second derivation unit 62 covers a part of the substantially rectangular shape (rectangular shape with rounded corners) adjacent to the region A3 when viewed from the front-rear direction (portion excluding the lower portion of the left end portion). Is formed. The opening part of the second derivation part 62 extends upward from the first derivation part 61, and the opening area is larger than that of the first derivation part 61.

  In the first derivation unit 61 and the second derivation unit 62, the opening areas per predetermined length (L2) in the horizontal direction are S3 and S4, respectively. The first derivation unit 61 and the second derivation unit 62 derive the cleaning water with a constant flow rate (for example, a flow rate at which the derivation pipe 42 is full) by the derivation path 40 through the water outlet 50, thereby opening the opening area. The flushing water having a flow rate corresponding to is discharged into the toilet bowl 20. Since the opening area S4 is larger than the opening area S3 of the first derivation section 61, the second derivation section 62 discharges flush water having a flow rate larger than that of the first derivation section 61 to the toilet bowl section 20 via the spout 50. To do.

  As shown in FIG. 3, the first derivation unit 61 is located on the far side from the center line C passing through the center in the left-right direction when viewed from the tip of the toilet bowl 20 in the derivation port 60. The first lead-out part 61 is located on the rear end side of the toilet bowl part 20 at a position close to the left end part of the toilet bowl part 20 (the left part of the first standing wall part 21). The first outlet 61 opens toward the direction along the left end of the toilet bowl 20 (the left portion of the first standing wall 21), and extends along the left portion of the first standing wall 21 through the water outlet 50. Wash water is allowed to flow on the inclined wall portion 22.

  As shown in FIG. 3, the second derivation unit 62 is located on the side close to the center line C in the derivation port 60. The 2nd derivation | leading-out part 62 is located in the side closer to the water storage part 24 rather than the 1st derivation | leading-out part 61 in the left-right direction in the rear end side of the toilet bowl part 20. FIG. Since the second lead-out portion 62 is open toward the water reservoir 24, the cleaning water flows on the inclined wall portion 22 toward the water reservoir 24 via the water outlet 50.

  The toilet 10 having the above-described configuration drains wash water stored in a wash tank (not shown) from a drain outlet, performs toilet flushing, and passes the outlet 50 from the outlet 40 through the spout 50. A flow similar to the desired flow of wash water (flow F1 and flow F2) can be created. Therefore, the toilet bowl 10 can wash | clean the inside surface of the toilet bowl part 20 favorably, and can discharge | emit filth from the toilet bowl part 20 favorably. In particular, in the toilet 10, the outlet 60 of the outlet path 40 is configured by the plurality of outlets (the first outlet 61 and the second outlet 62), so that the toilet bowl 20 is similar to the first embodiment. Can be improved in appearance, and the manufacturing cost can be reduced.

  As for the toilet bowl 10 of Example 2, the toilet bowl 20 is formed with a water outlet 50 connected to the inside. The lead-out path 40 has a lead-out opening 60 that discharges wash water to the toilet bowl 20 through the spout 50. For this reason, in the toilet bowl 10, the flow rate of the washing water is defined for each part of the toilet bowl 20 by the shape of the outlet 60 of the outlet path 40. Therefore, regardless of the shape of the spout 50 formed in the toilet bowl 20, the toilet 10 can discharge the flush water of a desired flow rate to the toilet bowl through the outlet 60 of the outlet 40.

<Example 3>
Next, Example 3 will be described.
The toilet bowl 10 according to the third embodiment is different from the first embodiment in the shape of the water outlet and the configuration of the outlet path 40. Other configurations are the same as those of the first embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIG. 4, the spout 70 of the third embodiment has a shape that extends in the left-right direction on the rear end side of the toilet bowl 20 and the left end extends upward.

  The lead-out path 40 leads the cleaning water at a constant flow rate (for example, a flow rate at which the entire opening area of the water discharge port 70 is filled with the cleaning water) to the water discharge port 70. If the lead-out path 40 is configured to derive the above-described constant flow of wash water, the lead-out port is configured to have the same size as the spout 70, or the right-side lead that distributes the wash water to the left and right sides together with the lead-out pipe 42. The structure provided with a pipe | tube may be sufficient.

  As shown in FIG. 4, the water discharge port 70 includes a first water discharge unit 71 and a second water discharge unit 72. The water discharge port 30 is formed adjacent to each other so that the first water discharge unit 71 and the second water discharge unit 72 are continuous. The first water discharger 71 is formed by cutting out a substantially rectangular (rectangular shape extending in the horizontal direction) region A5 of the first standing wall 21. The second water discharger 72 is formed by cutting out a substantially rectangular region (rectangular shape extending in the vertical direction) adjacent to the region A5 in the first standing wall portion 21.

  As for the 1st water discharging part 71 and the 2nd water discharging part 72, the opening area of an opening part is S5 and S6, respectively. The opening area is larger in S5 than in S6. The opening area per predetermined length (L3) in the horizontal direction of the second water discharger 72 is larger than the opening area per predetermined length (L3) in the horizontal direction of the first water discharger 71. The first water discharger 71 and the second water discharger 72 derive the cleaning water at a constant flow rate (for example, a flow rate at which the entire opening region of the water discharge port 70 is filled with the cleaning water) through the outlet channel 40, thereby opening the opening area. The flushing water having a flow rate corresponding to is discharged into the toilet bowl 20. The second water discharger 72 has a larger flow rate of cleaning water per predetermined length (L3) in the horizontal direction than the first water discharger 71.

  When the toilet 10 configured as described above drains the wash water stored in the wash tank (not shown) from the drain and performs toilet flushing, the wash water discharged from the spout 70 is mainly the first. A flow of cleaning water discharged from the water discharger 71 (flow F3 shown in FIG. 5) and a flow of cleaning water discharged mainly from the second water discharger 72 (flow F4 shown in FIG. 5) are created. The flow F3 flows down while turning around the inner surface of the toilet bowl 20 (the surface of the inclined wall portion 22). The flow F4 is a flow having a strong momentum toward the water reservoir 24 while turning on the inner surface of the toilet bowl 20 (the surface of the inclined wall portion 22). Thus, the toilet bowl 10 of Example 3 can produce the flow of the wash water which can discharge | emit waste well.

<Example 4>
Next, Example 4 will be described.
The toilet 10 of the fourth embodiment is different from the third embodiment in the shape of the spout. Other configurations are the same as those of the third embodiment, and the same configurations are denoted by the same reference numerals and detailed description thereof is omitted.

  As shown in FIG. 6, the water discharge port 80 of the fourth embodiment has a shape that extends in the left-right direction and that a portion closer to the right side extends upward from the left end portion. The water discharge port 80 includes a first water discharge unit 81, a second water discharge unit 82, and a third water discharge unit 83. The water discharge port 30 is formed adjacent to each other so that the first water discharge unit 81, the second water discharge unit 82, and the third water discharge unit 83 are continuous.

  As for the 1st water discharging part 81, the 2nd water discharging part 82, and the 3rd water discharging part 83, the opening area of an opening part is S7, S8, and S9, respectively. The opening area increases in the order of S8, S9, and S7. The second water discharger 82 has an opening area per predetermined length in the horizontal direction that is larger than the opening areas of the first water discharger 81 and the third water discharger 83. The first water discharger 81 and the third water discharger 83 have approximately the same opening area per predetermined length in the horizontal direction.

  The toilet 10 of Example 4 can produce the desired flow of washing water similar to that of the toilet 10 of Example 3 (the same flow as the flows F3 and F4 shown in FIG. 5).
