Description

本発明は大便器装置の改良に関するものである。   The present invention relates to an improvement of a toilet device.

従来、大便器装置のボウル洗浄は大便器のリム直下でボウル内面に沿って略水平にボウル側部より前方に洗浄水を供給するノズルにより洗浄水を吐水し、洗浄水をボウル全周に導くボウル内面に沿った均一な幅の棚を伝いながら、ボウル内へ洗浄水が流下することによって行われていた。   Conventionally, bowl cleaning of a toilet device is performed by discharging the cleaning water by a nozzle that supplies the cleaning water forward from the side of the bowl substantially horizontally along the inner surface of the bowl directly below the rim of the toilet bowl, and guiding the cleaning water to the entire circumference of the bowl. The washing water flowed into the bowl while traveling along a uniform width shelf along the inner surface of the bowl.

前記した従来の大便器装置の場合、ボウルの内面形状が前方では曲率が大きく、したがって、洗浄水に遠心力がつきすぎ、洗浄水のボウル外への飛び出したり飛び散ったりという不具合があった。また、洗浄水を伝わせる棚が均一なため、ボウルの各部位で均一にボウルへ洗浄水を流下させることができず、ボウルを十分に洗えないという不具合があった。上記問題は、特に給水源を水道の圧力を利用した大便器の場合、水圧の変動により洗浄水の勢いが変動するため、さらに重大な問題となった。   In the case of the conventional toilet device described above, the curvature of the bowl inner surface is large at the front, and accordingly, there is a problem that centrifugal force is applied to the washing water and the washing water jumps out of the bowl or scatters. In addition, since the shelves through which the wash water is transmitted are uniform, the wash water cannot be uniformly flowed down to the bowl at each part of the bowl, and the bowl cannot be sufficiently washed. The above problem has become a more serious problem, particularly in the case of a toilet using a water supply pressure as a water supply source, because the momentum of the washing water fluctuates due to fluctuations in the water pressure.

本発明は、上記課題を解決するためになされたもので、本発明の目的は、大便器のリム直下でボウル内面に沿って略水平にボウル側部より前方に洗浄水を供給するノズルを備えた大便器装置において、洗浄水のボウル外への飛び出しおよび飛散りをなくし、またボウルの洗浄性能を向上させた大便器装置を提供することにある。 The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a nozzle for supplying cleaning water forward from the side of the bowl substantially horizontally along the inner surface of the bowl directly below the rim of the toilet bowl. Another object of the present invention is to provide a toilet apparatus that eliminates the splashing and splashing of wash water out of the bowl and improves the cleaning performance of the bowl.

上記の目的を達成するために本発明は、大便器のリム直下でボウル内面に沿って略水平にボウル部の後方側部より前方に洗浄水を供給する１つのノズルと、洗浄水をボウル全周に導くボウル内面に沿った棚と、この棚の上方に設けられたリム部と、を備えた大便器装置において、リム部は棚から上方に向けて内側に張り出すオーバーハング形状となっており、棚は、ボウル部の側部では略水平で且つボウル部の前方部ではボウル部中央に向かって下方に傾斜し、ノズルから噴出した洗浄水が棚に沿って略一周を旋回するように構成されていることを特徴としている。
このように構成された本発明においては、棚が、ボウル部の側部では略水平で、ボウル部の前方部ではボウル部中央に向かって下方に傾斜し、１つのノズルから噴出した洗浄水が棚に沿って略一周を旋回するので、ボウル部の前方部で洗浄水の遠心力が大きく、ボウルに洗浄水が流下し難い場合であっても、洗浄水が流下し易くなり、洗浄水のボウル外への飛び出しおよび飛散りをなくし、ボウル洗浄性能を改善できる。 In order to achieve the above object, the present invention provides a nozzle for supplying cleaning water to the front of the rear side of the bowl portion substantially horizontally along the inner surface of the bowl just below the rim of the toilet bowl, In a toilet device including a shelf along the inner surface of the bowl leading to the periphery and a rim portion provided above the shelf , the rim portion has an overhang shape that projects inwardly upward from the shelf. cage, shelves, as the front portion of and the bowl portion is substantially horizontal in the sides of the bowl portion inclined downwardly toward the central bowl portion, the washing water ejected from the nozzle is pivoted substantially continuously along the shelf It is characterized by being composed .
In the present invention configured as described above, the shelf is substantially horizontal at the side of the bowl part, is inclined downward toward the center of the bowl part at the front part of the bowl part, and the washing water ejected from one nozzle is Since it swirls approximately one turn along the shelf, even if the centrifugal force of the washing water is large at the front part of the bowl and it is difficult for the washing water to flow into the bowl, the washing water can easily flow down. Eliminates out and splashes out of the bowl and improves bowl cleaning performance.

本発明に係わる第一の実施形態について説明する。
図１は第一の実施例の大便器装置をボウル洗浄時の洗浄水の流れを示した図である。大便器装置１には、大便器のリム１５直下でボウル部１１の内面に沿って略水平にボウル部１１の側部より前方に洗浄水を供給するノズル２１が取付けられ、前記ノズル２１は給水源である水道管２３に接続され、水道管２３からノズル２１までの間に開閉バルブ２２が設けられている。開閉バルブ２２は電気式・メカ式いずれでも良く、電気式の場合は開閉バルブの開閉を制御する制御部（図示せず）へと接続されている。本実施例では給水源は、水道圧を利用したものとしているが、タンク式でも加圧ポンプ式でも何であっても良い。 A first embodiment according to the present invention will be described.
FIG. 1 is a view showing a flow of washing water when the toilet apparatus of the first embodiment is washed in a bowl. The toilet device 1 is provided with a nozzle 21 for supplying cleaning water to the front side of the bowl portion 11 substantially horizontally along the inner surface of the bowl portion 11 immediately below the rim 15 of the toilet bowl. An open / close valve 22 is provided between the water pipe 23 and the nozzle 21 and is connected to a water pipe 23 that is a water source. The on-off valve 22 may be either an electric type or a mechanical type. In the case of an electric type, the on-off valve 22 is connected to a control unit (not shown) that controls the opening and closing of the on-off valve. In this embodiment, the water supply source uses water pressure, but it may be any tank type or pressure pump type.

また、ボウル部１１のノズル２１が取付けられている高さより若干したの位置には、ノズル２１より吐水された洗浄水をボウル部１１へ全周へ導くための棚１４を設け、棚の上方には棚１４を覆うようなリム形状１５が形成されている（図２）。また、この棚形状およびリム形状は、図６のようなタイプのリム形状でも良い。さらに、本実施例では、図３に示す如く大便器装置外形形状１２とボウル内面形状１３の間のリム１５の幅を、側部より前方に行くにつれて大きくなるように構成されている。   A shelf 14 is provided at a position slightly higher than the height at which the nozzle 21 of the bowl portion 11 is attached, and the cleaning water discharged from the nozzle 21 is guided to the bowl portion 11 to the entire circumference. A rim shape 15 is formed to cover the shelf 14 (FIG. 2). The shelf shape and the rim shape may be a rim shape of the type shown in FIG. Further, in this embodiment, as shown in FIG. 3, the width of the rim 15 between the toilet device outer shape 12 and the bowl inner surface shape 13 is configured to increase as it goes forward from the side portion.

本発明に係わる第一の実施例によると、大便器装置１のボウル内面１３の前方部は通常曲率が大きく、洗浄水の流速エネルギを損失してしまうが、本実施例では曲率が小さくなり、洗浄水がスムーズに伝わるようになり、その結果給水源の圧力が低圧の場合でも、ボウル後端部まで洗浄水が伝わり、ボウル洗浄を行うことができる。また、大便器装置１のボウル内面１３の前方部は通常曲率が大きく、なおかつ流速が非常に速いため、洗浄水が飛び出す可能性があるが、本実施例では曲率が小さくなり、洗浄水の遠心力が小さくなり、ボウル前方部での洗浄水のボウル外への飛び出しおよび飛散りを小さくすることができる。   According to the first embodiment of the present invention, the front portion of the bowl inner surface 13 of the toilet device 1 has a large curvature and loses the flow energy of the washing water, but in this embodiment, the curvature becomes small, As a result, the cleaning water is transmitted smoothly, and even when the pressure of the water supply source is low, the cleaning water is transmitted to the rear end of the bowl, and the bowl can be cleaned. In addition, the front portion of the bowl inner surface 13 of the toilet device 1 has a large curvature and a very high flow velocity, and thus the washing water may jump out. However, in this embodiment, the curvature becomes small and the washing water is centrifuged. The force is reduced, and the jumping and splashing of cleaning water out of the bowl at the front part of the bowl can be reduced.

本発明に係わる第二の実施形態について説明する。
図４は第二の実施例の大便器装置をボウル洗浄時の洗浄水の流れを示した図である。大便器装置１には、大便器のリム１５直下でボウル部１１の内面に沿って略水平にボウル部１１の側部より前方に洗浄水を供給するノズル２１が取付けられ、前記ノズル２１は給水源である水道管２３に接続され、水道管２３からノズル２１までの間に開閉バルブ２２が設けられている。開閉バルブ２２は電気式・メカ式いずれでも良く、電気式の場合は開閉バルブの開閉を制御する制御部（図示せず）へと接続されている。本実施例では給水源は、水道圧を利用したものとしているが、タンク式でも加圧ポンプ式でも何であっても良い。 A second embodiment according to the present invention will be described.
FIG. 4 is a view showing a flow of cleaning water when the bowl apparatus of the second embodiment is cleaned. The toilet device 1 is provided with a nozzle 21 for supplying cleaning water to the front side of the bowl portion 11 substantially horizontally along the inner surface of the bowl portion 11 immediately below the rim 15 of the toilet bowl. An open / close valve 22 is provided between the water pipe 23 and the nozzle 21 and is connected to a water pipe 23 that is a water source. The on-off valve 22 may be either an electric type or a mechanical type. In the case of an electric type, the on-off valve 22 is connected to a control unit (not shown) that controls the opening and closing of the on-off valve. In this embodiment, the water supply source uses water pressure, but it may be any tank type or pressure pump type.

また、ボウル部１１のノズル２１が取付けられている高さより若干したの位置には、ノズル２１より吐水された洗浄水をボウル部１１へ全周へ導くための棚１４を設けており、棚の上方には棚を覆うようなリム形状１５が形成されている（図２）。また、この棚形状およびリム形状は、図６のようなタイプのリム形状でも良い。本実施例では、前記棚１４を図５の如く、前方部でなくした構成とする。また、図７に示すようなタイプのリム形状で棚１４をなくして構成しても良い。
本発明に係わる第二の実施例によると、ボウル１１内面で曲率が比較的大きく洗浄水の遠心力が大きくボウル１１に洗浄水が流下し難い前方で、棚１４の幅が最小となることで、洗浄水が流下し易くなり、ボウル洗浄性能を改善できる。 Further, a shelf 14 is provided at a position slightly higher than the height at which the nozzle 21 of the bowl portion 11 is attached to guide the wash water discharged from the nozzle 21 to the bowl portion 11 to the entire circumference. A rim shape 15 is formed above the shelf to cover the shelf (FIG. 2). The shelf shape and the rim shape may be a rim shape of the type shown in FIG. In this embodiment, the shelf 14 is not the front part as shown in FIG. Further, the rim shape as shown in FIG. 7 may be used without the shelf 14.
According to the second embodiment of the present invention, the width of the shelf 14 is minimized in the front where the curvature is relatively large on the inner surface of the bowl 11 and the centrifugal force of the washing water is large and the washing water does not easily flow into the bowl 11. The washing water can easily flow down and the bowl washing performance can be improved.

図８は第三の実施例の大便器装置をボウル洗浄時の洗浄水の流れを示した図である。大便器装置１には、大便器のリム１５直下でボウル部１１の内面に沿って略水平にボウル部１１の側部より前方に洗浄水を供給するノズル２１が取付けられ、前記ノズル２１は給水源である水道管２３に接続され、水道管２３からノズル２１までの間に開閉バルブ２２が設けられている。開閉バルブ２２は電気式・メカ式いずれでも良く、電気式の場合は開閉バルブの開閉を制御する制御部（図示せず）へと接続されている。本実施例では給水源は、水道圧を利用したものとしているが、タンク式でも加圧ポンプ式でも何であっても良い。 A third embodiment according to the present invention will be described.
FIG. 8 is a view showing a flow of washing water when the bowl apparatus of the third embodiment is washed with a bowl. The toilet device 1 is provided with a nozzle 21 for supplying cleaning water to the front side of the bowl portion 11 substantially horizontally along the inner surface of the bowl portion 11 immediately below the rim 15 of the toilet bowl. An open / close valve 22 is provided between the water pipe 23 and the nozzle 21 and is connected to a water pipe 23 that is a water source. The on-off valve 22 may be either an electric type or a mechanical type. In the case of an electric type, the on-off valve 22 is connected to a control unit (not shown) that controls the opening and closing of the on-off valve. In this embodiment, the water supply source uses water pressure, but it may be any tank type or pressure pump type.

また、ボウル部１１のノズル２１が取付けられている高さより若干したの位置には、ノズル２１より吐水された洗浄水をボウル部１１へ全周へ導くための棚１４を設けており、棚の上方には棚を覆うようなリム形状１５が形成されている（図９）。また、この棚形状およびリム形状は、図６のようなタイプのリム形状でも良い。さらに本実施例では、前記棚１４は側部では図９の如く略水平であり、また、前方部および後方部ではボウル中央に向かって傾斜させた構成とする。さらに、本実施例では、前記棚１４には前方部および後方部に、ボウル中央付近を向くように線状の凸形状を設けた構成とする（図８、図１０）。   Further, a shelf 14 is provided at a position slightly higher than the height at which the nozzle 21 of the bowl portion 11 is attached to guide the wash water discharged from the nozzle 21 to the bowl portion 11 to the entire circumference. A rim shape 15 is formed above the shelf to cover the shelf (FIG. 9). The shelf shape and the rim shape may be a rim shape of the type shown in FIG. Furthermore, in this embodiment, the shelf 14 is substantially horizontal at the side as shown in FIG. 9, and is inclined toward the center of the bowl at the front and rear portions. Further, in this embodiment, the shelf 14 is provided with a linear convex shape at the front part and the rear part so as to face the vicinity of the center of the bowl (FIGS. 8 and 10).

本発明に係わる第三の実施例によると、ボウル１１内面で曲率が比較的大きく洗浄水の遠心力が大きくボウル１１に洗浄水が流下し難い前方部および後方部でも、棚１４をボウル中央に向かって傾斜させた構成とし、さらに棚１４にボウル中央付近を向くように凸形状を設けた構成としたため、洗浄水が流下し易くなり、ボウル洗浄性能を改善できる。   According to the third embodiment of the present invention, the shelf 14 is placed at the center of the bowl 11 even at the front and rear portions where the curvature is relatively large on the inner surface of the bowl 11 and the centrifugal force of the washing water is large and the washing water does not easily flow into the bowl 11. Since the shelf 14 is inclined and the convex shape is provided on the shelf 14 so as to face the vicinity of the center of the bowl, the washing water can easily flow down and the bowl washing performance can be improved.
