Description

  The present invention relates to a toilet apparatus in which a cabinet is installed at the rear part of a toilet bowl.

  In order to realize a high-quality toilet space, a cabinet may be installed at the rear of the toilet bowl, and a tank for supplying cleaning water to the toilet bowl may be housed inside the cabinet to conceal the tank. In this configuration, when a hand-washing machine for the user to wash their hands is provided at the top and center of the cabinet, it is placed on the drain port below the bowl part of the hand-washing machine and the upper part of the tank that receives the water flowing in from the drain port. In some cases, the position of the opening in the lid that has been formed cannot be provided at a position overlapping the top view. In this case, a water distribution means such as a bellows pipe is used to connect the drain outlet below the bowl and the opening on the lid placed on the top of the tank, and supply water from the drain to the tank. Is done. (For example, Patent Document 1) However, when the upper surface of the cabinet and the upper surface of the bowl are equal and the bowl portion is deeply embedded in the cabinet, the distance between the upper portion of the tank and the lower end of the bowl portion is very close. For this reason, water distribution means such as bellows pipes could not be employed.

Japanese Patent Laid-Open No. 11-324058

  Considering a method that can supply water from the drain outlet to the tank without adopting water distribution means such as bellows pipes under the condition that the distance between the upper part of the tank and the lower end of the bowl part is very close, the upper surface of the tank lid Thus, a method of forming an inclination with the opening as the center is conceivable. However, in the above method, when the water falling from the drain is drained to the upper slope of the lid, the entire tank lid is vibrated, generating a loud sound, and the quality of the toilet space is impaired. And the problem that water splashes and water splashes in the cabinet has been born.

  In order to solve the above-described problems, the toilet apparatus according to the present invention includes a cabinet that is installed behind the toilet bowl and stores a tank that supplies cleaning water to the toilet bowl, and a hand-washer installed on the upper surface of the cabinet. The handwasher includes a water discharging member that discharges water supplied from a water supply source, a bowl portion that receives water discharged from the water discharging member, and water that is opened below the bowl portion and received by the bowl portion. A lid opening for allowing the water drained from the drain port to flow into the tank, and a tank lid covering the upper side of the tank. Inside the outer periphery, there is provided a tray having a drain receiving surface that is open on the upper surface of the tank lid and a standing wall that rises upward around the drain receiving surface. With opening A toilet device that is provided in an overlapping position when viewed from above, and that receives water drained from the drainage outlet on the drainage receiving surface in the standing wall and flows into the tank from the lid opening via the dish opening is there.

  According to the present invention, in order to allow the water drained from the drain of the hand-washer to flow into the tank, a tray that is a separate member from the tank lid is provided inside the outer periphery of the tank lid, and the water drained from the drain It is comprised so that it may catch on the drainage receiving surface of a saucer. Since the area of the drainage receiving surface that receives water from the drainage port is smaller than the area of the tank lid, the amplitude of vibration that occurs when drainage from the drainage port is received by the drainage receiving surface is received by the tank lid. It becomes smaller than the amplitude of the vibration that occurs. Therefore, it is possible to reduce the noise generated to allow the water drained from the drain of the hand-washer to flow into the tank. Furthermore, since there are standing walls, water is less likely to scatter.

  In the present invention, preferably, the drainage receiving surface is a toilet apparatus provided with water flow inhibiting means for inhibiting a water flow flowing through the drainage receiving surface toward the standing wall.

  When water drained from the drainage falls to the drainage receiving surface, spreads on the drainage receiving surface, and the water collides strongly with the standing wall, water is scattered from above the standing wall into the cabinet. A challenge has arisen. In addition, when water collides strongly with a standing wall, the amplitude of the vibration of the saucer is increased, resulting in a new problem of generating a loud sound.

  According to this configuration, the water receiving surface is provided with water flow inhibiting means that inhibits the flow of water flowing through the drain receiving surface toward the standing wall, and the water that has been drained from the drain port and dropped to the drain receiving surface is The water that spreads on the drainage receiving surface and whose flow is weakened by the water flow blocking means collides with the standing wall, so that the momentum of the water colliding with the standing wall can be attenuated. Therefore, it is possible to prevent water from splashing into the cabinet from above the standing wall. Therefore, it is possible to reduce the noise generated to allow the water drained from the drain of the hand-washer to flow into the tank.

  In this invention, Preferably, it is a toilet apparatus by which the level | step difference was provided in the receiving tray from the drainage receiving surface to the standing wall as a water flow inhibition means.

  According to this configuration, the tray is provided with a step from the drainage receiving surface to the standing wall of the tray, and the water drained from the drainage port and falling to the drainage receiving surface spreads on the drainage receiving surface and forms a step. The water that has collided and once climbed the step collides with the standing wall, so that the momentum of the water colliding with the standing wall can be attenuated. Therefore, it is possible to prevent water from splashing into the cabinet from above the standing wall. Furthermore, since most of the water that goes up the standing wall and returns to the saucer falls to the stepped portion, vibration to the saucer can be reduced. Therefore, it is possible to reduce the noise generated to allow the water drained from the drain of the hand-washer to flow into the tank.

  In this invention, Preferably, the thickness of the member which comprises a saucer is a toilet apparatus thicker than the thickness of the member which comprises a tank cover.

  According to this structure, since the thickness of the member which comprises a saucer is thicker than the thickness of the member which comprises a tank cover, a saucer is hard compared with a tank cover, and it can suppress the amplitude of vibration small. On the other hand, since the tank lid is softer than the saucer, the amplitude of vibration is large, and the tank lid flexibly follows the vibration of the saucer caused by the water falling from the drain port to the drain receiving surface. It can absorb and dampen vibration. Therefore, it is possible to reduce the noise generated to allow the water drained from the drain of the hand-washer to flow into the tank.

  In the present invention, preferably, the drain outlet is a toilet device in a position having no overlapping region in the top view with respect to the lid opening and the dish opening.

  According to this configuration, even in the above-described invention, the water falling sound in the tank that is inevitably generated when water falls from the tray into the tank is reflected in the tank, and the lid opening and the dish opening Since the sound is transmitted to the toilet space from the opening below the bowl portion, sound sufficiently attenuated inside the cabinet is transmitted to the toilet space. That is, since the drain outlet below the bowl portion does not overlap with the lid opening and the dish opening in the top view, the sound does not directly come out from the drain opening through the lid opening and the dish opening. The sound that is echoed and attenuated inside the cabinet is transmitted from the drain to the toilet space. Therefore, it is possible to reduce the noise generated to allow the water drained from the drain of the hand-washer to flow into the tank.

  In this invention, Preferably, it is a toilet apparatus which has an engaging part engaged with a tank cover in a saucer, and an engaged part engaged with a saucer in a tank cover.

  According to this configuration, it is possible to prevent movement of the tray that vibrates by receiving the water falling from the drain port from the predetermined position in the rotational direction or the horizontal direction. Further, since the tray and the tank lid are engaged, the vibration of the tray is reliably transmitted from the engaging portion to the tank lid, and the tray and the tank lid are further vibrated as a unit. Vibration can be damped. Therefore, it is possible to reduce the noise generated to allow the water drained from the drain of the hand-washer to flow into the tank.

  According to the aspect of the present invention, it is possible to reduce the sound generated to allow the water drained from the drain port of the hand-washer to flow into the tank. Moreover, scattering of the water drained from the drain of the hand-washing machine inside the cabinet into the cabinet can be prevented.
