The flushing water discharged from the rear to the front of the toilet body 1 flows along the inner surface of the toilet body 1 and washes out excreta by an inertia caused when it flows in the turning passage part 3. The degree of the projection of the rim part 2 is gradually increased from the side part 1a to the front end 1b of the toilet body 1, and maximized at the front end 1b. The rim part does not almost project at the side part 1a. <P>COPYRIGHT: (C)2008,JPO&INPIT

Description

  The present invention integrally forms a rim portion projecting inwardly at an upper end opening edge of a bowl-shaped toilet body body opened upward, and the flushing water flowing along the circumferential direction of the opening below the rim portion vigorously The present invention relates to a flush toilet that flushes filth through the inner surface of the main body.

  Conventionally, as shown in FIG. 4, a rim portion 2 that protrudes inward is integrally formed on the upper end opening edge of a bowl-shaped toilet body 1 that opens upward, and along the circumferential direction of the opening below the rim portion 2. The flush circuit part 3 through which the wash water flows is provided, and the wash water discharged forward from the discharge port 9 provided at the rear part of the toilet body 1 flows along the inner surface of the toilet body 1 with a momentum flowing through the swirl circuit part 3. A flush toilet that rinses away filth is known (Patent Document 1: Japanese Patent Application Laid-Open No. 2004-11413). Here, the rim part 2 is formed in the shape of a bent plate at the upper end opening edge of the toilet body 1, and the rim part 2 and a shelf-like part 4 facing below the rim part 2 project from the inner surface of the toilet body 1, A grooved lathe 3 is opened inward between the rim 2 and the shelf 4.

Therefore, in this flush toilet, the wash water discharged forward from the discharge port 9 flows vigorously along the turning circuit portion 3, and at that time, the rim portion 2 scatters and overflows the wash water. The washing water is prevented from flowing through the inner surface of the toilet body 1 while swirling vigorously to wash away the filth, and is removed from an outlet (not shown) provided at the bottom of the toilet body 1. Further, in this case, the turning circuit portion 3 has a groove shape opened inward, so that it is easy to clean when the inside is dirty.

  However, in the flush toilet as the conventional example, the rim portion 2 is formed with the same degree of protrusion over the entire periphery of the upper end opening of the toilet body 1. Therefore, the opening area of the upper end opening of the toilet body 1 is reduced as a whole, and it is difficult to receive urine for male urine. Moreover, if the protrusion degree of the rim | limb part 2 becomes large more than necessary, useless material will be used for the toilet bowl main body 1, and it will also lead to a cost increase. By the way, the washing water discharged forward from the rear part of the toilet body 1 has a maximum resistance flowing in the turning circuit part 3 at the front end of the toilet body 1, and is likely to scatter or overflow upward. In the side part of the toilet body 1, the resistance is small and it flows relatively smoothly.

  The present invention has been made in view of the above-mentioned background art, and its problem is to optimize the protrusion degree of the rim portion in accordance with the resistance when the washing water flows in the turning circuit portion, and to the upper side of the washing water. Efficiently prevents splashing and overflowing, and the opening area of the upper end opening of the toilet body is expanded to the side, making it easier to receive urine for men's urine, and reducing waste materials and reducing costs It is to provide a flush toilet that can be connected.

  In order to solve the above-mentioned problems, in the invention described in claim 1 of the present application, a rim portion projecting inward is integrally formed at an upper end opening edge of a bowl-shaped toilet body body opened upward, and is opened below the rim portion. This is a flush toilet that has a swirl circuit that flows along the circumferential direction, and the wash water discharged forward from the rear of the toilet body flows through the swirl circuit and travels along the inner surface of the toilet body to wash away filth. The degree of protrusion of the rim portion is gradually increased from the side portion of the toilet body to the front end portion so as to be maximized at the front end portion, and hardly protrudes at the same side portion.

  Further, in the flush toilet according to the present invention, the rim portion is formed in a bent plate shape at the upper end opening edge of the toilet body, and the rim portion and the shelf-like portion facing below the rim portion are formed on the toilet body. It is characterized in that it is a groove-shaped turning circuit portion that protrudes from the inner surface and opens inward between the rim portion and the shelf-like portion.

  In the flush toilet which is the invention according to claim 1 of the present application, the wash water discharged toward the front flows vigorously along the turning circuit portion, and at that time, the rim portion causes scattering or overflow of the wash water upward. The washing water is prevented from flowing through the inner surface of the toilet body while flowing down and washing away the filth.

  And the degree of protrusion of the rim part gradually increases from the side part of the toilet body to the front end part and becomes the maximum at this front end part, and hardly protrudes at the same side part, so the resistance when washing water flows in the turning circuit part Accordingly, the degree of protrusion of the rim portion is optimum, and splashing and overflowing of the cleaning water can be efficiently prevented. Moreover, in this case, the opening area of the upper end opening of the toilet body is expanded to the side, making it easy to receive urine for male urine, reducing wasteful materials and reducing costs.

  In the flush toilet as claimed in claim 2 of the present invention, in particular, the rim portion is formed in the shape of a bent plate, the material thereof is further reduced, and the rim portion and a shelf protruding below the rim portion. Since this is a groove-shaped turning circuit that opens inward, the cleaning water is easily regulated along the turning circuit, and the speed of the cleaning water is increased to enhance the turning momentum. It is also easy to clean the inside of the turning circuit.

  1 to 3 show an embodiment corresponding to all of claims 1 and 2 of the present application. In the flush toilet of this embodiment, a rim portion 2 that protrudes inward is integrally formed at the upper end opening edge of a bowl-shaped toilet body 1 that opens upward, and is washed along the circumferential direction of the opening below the rim portion 2. The swirl circuit part 3 through which water flows is provided, and the washing water discharged forward from the rear part of the toilet body 1 flows along the inner surface of the toilet body 1 with the force of flowing through the swirl circuit part 3 to wash away filth. In this case, the degree of protrusion of the rim part 2 is gradually increased from the side part 1a of the toilet body 1 to the front end part 1b so as to be maximized at the front end part 1b, and hardly protrudes at the side part 1a. Yes.

  Moreover, in the flush toilet of this embodiment, the rim | limb part 2 is formed in the upper end opening edge of the toilet bowl main body 1 in the shape of a folding plate piece, and the shelf-like part 4 which opposes the rim | limb 2 and the downward direction is formed in the inner surface of the toilet bowl main body 1. And a groove-like lathe circuit portion 3 opened inward between the rim portion 2 and the shelf-like portion 4.

  Hereinafter, the flush toilet of this embodiment will be described in more detail. As shown in FIG. 1, the flush toilet of this embodiment is a western-style toilet that can be used while sitting. The toilet body 1 is in the shape of a bowl that opens upward, and is formed of a synthetic resin such as pottery or acrylic resin, and is installed and fixed on the floor surface of the toilet room. A local cleaning device 5 is installed on the rear end of the toilet body 1, and a heating toilet seat 6 and a toilet lid 7 are rotatably supported on the local cleaning device 5. Is placed on the upper end opening of the toilet body 1 as necessary.

  On the back surface of the toilet seat 6, cushioning legs 8 made of rubber or the like are disposed on the left and right sides near the front and rear ends, and the toilet seat 6 is placed on the upper end opening of the toilet body 1 via the cushioning legs 8. Is done. At that time, the buffer leg 8 is abutted and supported on the rim portion 2 that protrudes relatively large from the upper end opening edge of the toilet body 1. Further, a nozzle (not shown) of the local cleaning device 5 protrudes from the rear portion of the bowl of the toilet body 1 so as to be able to advance and retreat. The local part of the human body seated on the toilet seat 6 can be washed.

  A discharge port 9 is provided on one side of the rear portion of the bowl of the toilet body 1, and the wash water is discharged (A) forward from the discharge port 9 and swung along the turning circuit unit 3. After that, the momentum is maintained, it becomes a spiral flow (B), flows down the inner surface of the toilet body 1 to wash away the waste, and is removed together with the waste from an outlet (not shown) provided at the bottom of the toilet body 1. . In addition, as for the washing water which wash | cleans the inside of the bowl of the toilet bowl main body 1, tap water may be discharged by the pressure and the water separately stored in the tank may be discharged by the pump pressure.

  As shown in FIG. 2, the upper end opening of the toilet body 1 has a front side formed in a substantially arc shape and a rear side formed in a substantially straight line shape. The upper edge opening edge of the toilet body 1 is integrally formed with a rim portion 2 protruding inward on the front side and the rear side, and the rim portion 2 is not formed on both side portions 1a of the toilet body 1. . In this case, the degree of protrusion of the rim portion 2 gradually increases from the both side portions 1a of the toilet body 1 to the front end portion 1b and becomes maximum at the front end portion 1b, and does not protrude from the both side portions 1a.

  That is, as shown in FIG. 3 (a), the rim portion 2 is not protruded from the side portion 1a of the toilet body 1, and the rim is formed at the front end portion 1b of the toilet body 1 as shown in FIG. 3 (b). The part 2 is protruded with the maximum protrusion amount. In addition, as shown with a dashed-two dotted line in Fig.3 (a), in the side part 1a of the toilet bowl body 1, the rim | limb part 2 may be protrudingly provided with a slight protrusion amount. The rim portion 2 is formed in a bent plate shape at the upper opening edge of the toilet body 1, and the rim portion 2 and a shelf-like portion 4 facing below the rim portion 2 project from the inner surface of the toilet body 1, A grooved lathe 3 is opened inward between the portion 2 and the shelf 4.

  The wash water is guided by the groove-shaped slewing circuit portion 3 and swivels. At that time, as shown in FIG. 3A, the side portion 1a of the toilet body 1 has a small resistance to flow of the wash water. The washing water hardly scatters or overflows upward, and therefore the protruding amount of the rim portion 2 may be small. However, as shown in FIG. 3 (b), at the front end 1b of the toilet body 1, the resistance of the washing water to flow is large and the washing water is likely to scatter or overflow upward. The protruding amount of 2 is increased. In the front end portion 1b of the toilet body 1, the peripheral wall is inclined more outward than the side portion 1a, and the wash water is likely to scatter or overflow upward, but the rim portion 2 that protrudes greatly It also prevents.

  Further, in this case, the lower side of the inner tip of the rim portion 2 and the vicinity of both inner and outer ends of the shelf-like portion 4 are formed in an R shape, so that the washing water hardly falls off from the inner tip of the rim portion 2. It flows smoothly down the inner surface of the toilet body 1 along the shelf 4. Therefore, it is difficult for dirt to adhere to the turning circuit portion 3, and even if it becomes dirty, it can be easily cleaned. In addition, as shown with a dashed-two dotted line in FIG. 3, you may form the site | part which becomes thick under the shelf-like part 4 of the toilet bowl body 1 in a hollow shape, so that further material reduction and Weight reduction is achieved.

  Therefore, in the flush toilet of this embodiment, the wash water discharged forward from the discharge port 9 flows vigorously along the turning circuit portion 3, and at that time, the rim portion 2 scatters the wash water upward. Water is prevented from overflowing, and the washing water flows down while vigorously swirling the inner surface of the toilet body 1 to wash away the filth.

  And since the protrusion degree of the rim | limb part 2 becomes large gradually from the both-sides part 1a of the toilet body 1 to the front-end part 1b, and becomes the maximum at this front-end part 1b, it does not protrude in the both-sides part 1a. The degree of protrusion of the rim portion 2 is optimized not to be unnecessarily large, and is optimally adapted according to the resistance when flowing through the inside 3, and splashing or overflowing of the washing water is efficiently prevented. In addition, in this case, the opening area of the upper end opening of the toilet body 1 is expanded from the middle to the both sides on the rear side, making it easy to receive urine for male urine, reducing wasteful materials and reducing costs. It is connected.

  Moreover, in the flush toilet of this embodiment, the rim | limb part 2 is formed in the shape of a bending plate piece, and the material is further reduced. In addition, a groove-shaped lathe circuit portion 3 is formed inwardly between the rim portion 2 and the shelf-like portion 4 projecting below the rim portion 2. However, it is easy to follow along the guide, the speed of the washing water is increased, the momentum of the swirling is strengthened, and the inside of the turning circuit portion 3 can be easily cleaned.
