Description

  The present invention relates to a local cleaning apparatus.

  Patent Document 1 discloses a conventional local cleaning device. This local cleaning apparatus has a base member that is placed on the upper surface of the rear part of a Western-style toilet body having a toilet bowl. The base member is provided with a reserve tank, a hot water tank communicating with the reserve tank via a pump, and a nozzle capable of ejecting cleaning water supplied from the hot water tank. The base member has a drain opening that opens above the rear part of the toilet bowl when placed on the rear upper surface of the western-style toilet body. The base member is provided behind the drain port and has an inflow portion through which waste water discharged from the reserve tank flows in via a hose. The inflow portion is formed from a substantially cylindrical peripheral wall that rises on the upper surface of the base member and has a notch in the vertical direction, and a lid member that is connected to the upper end of the peripheral wall and provided with an inflow port. Further, the base member has a guide wall that is raised from the upper surface so as to surround the inflow portion and the drainage groove, and guides waste water from the inflow portion to the drainage port.

  In this local cleaning device, when a larger amount of cleaning water than the flow rate of cleaning water ejected from the nozzle is supplied to the reserve tank, the excessive supply of cleaning water is discarded as water and flows into the inflow portion via the hose, and the guide wall The top surface of the base member surrounded by can be drained and drained from the drain port into the toilet bowl.

JP-A-8-93030

  However, in the conventional local cleaning device, since the upper part in the guide wall is opened, there is a possibility that the waste water that has flowed into the inflow portion scatters into the local cleaning device. For this reason, in order to prevent waste water from splashing, the guide wall must be raised, and a space for this is required in the local cleaning device.

  The present invention has been made in view of the above-described conventional situation, and solves the problem of providing a local cleaning device that can drain waste water without splashing and can effectively use space. It is an issue that should be done.

The local cleaning device of the present invention is a base member mounted on a rear upper surface of a western-style toilet body having a toilet bowl, to which a hot water tank device and a nozzle capable of ejecting cleaning water supplied from the hot water tank device are attached. In a local cleaning device having
The base member has a drain opening that opens above the rear part of the toilet bowl when placed on the rear upper surface of the western-style toilet body, and waste water that is provided on one of the left and right upper surfaces and is drained from the hot water tank device And a water collecting part that flows in through a hose,
The water collecting portion is formed from a peripheral wall that is raised on the upper surface of the base member, the drain port side is open, and a lid member that has an upper surface connected to the upper end of the peripheral wall.
The lid member is a part of the upper surface, and a portion that is horizontally separated from the portion where the peripheral wall is opened is formed by expanding upward, and an inflow port to which the downstream end of the hose is connected is provided. It is characterized by having an inflow portion.

  In this local cleaning device, the waste water drained from the hot water tank device flows into the inflow portion formed in the lid member via the hose. The discarded water that has flowed into the inflow portion flows downward, and thereafter, the upper portion is closed by a lid member, flows through the upper surface of the base member surrounded by the peripheral wall, and is drained into the toilet bowl. In this way, the wastewater that has flowed into the inflow portion from the inflow port is changed in the flowing direction and flows toward the drain port while spreading in the water collection portion, so that the momentum is attenuated. For this reason, waste water can be smoothly drained into the toilet bowl from the drain outlet. Moreover, since the upper part of the water collection part is closed by the lid member, it is possible to reliably prevent the waste water from scattering into the local cleaning device. Moreover, the lid member is only partially expanded upward as an inflow portion, and the height of other portions is kept low. For this reason, other equipment of the local cleaning device can be arranged above the lid member while avoiding the inflow portion, and the space can be used effectively.

  Therefore, the local cleaning apparatus of the present invention can drain the waste water without splashing it, and can effectively use the space.

  The hot water tank device is provided with a drainage mechanism and an atmosphere release mechanism, and the drainage mechanism and the atmosphere release mechanism are provided with outlets for discharging waste water, and the upstream ends of separate hoses are connected to each outlet. Can be done. In this case, waste water discharged from a plurality of locations of the hot water tank apparatus can be collected and drained into the toilet bowl. For this reason, compared with the case where it drains separately, a number of parts can be decreased and a structure is simplified. Therefore, the local cleaning device can be easily assembled.

  The inflow port may be formed at the upper part of the side surface of the inflow portion. In this case, since an inflow port is formed in the upper part of the inflow part expanded upwards, a hose can be easily connected to an inflow port.

  The water collecting portion has a horizontally long shape extending in the left-right direction of the base member, and the inflow portion can be formed so as to be biased closer to the left and right end portions of the base member. In this case, the inflow part expanded upward is formed close to the left and right ends of the base member. For this reason, avoiding the inflow portion, it is possible to arrange other devices for the local cleaning device at the left and right central portions of the base member, and the space can be used effectively.
