Assembling can be simplified by integrating the nozzle side system and the water discharge side system.

Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a sanitary cleaning device that is attached to a seat-type flush toilet and sprays cleaning water to private parts, and particularly relates to a nozzle device for spraying the cleaning water. .

[Conventional technology]

In recent years, sanitary cleaning devices with a private parts cleaning function that are integrated into flush toilet bowls or are attached as an option have rapidly become popular. This sanitary cleaning device is equipped with a hot water tank that heats the cleaning water, a nozzle device that sprays the cleaning water from the hot water tank toward private parts, and has a structure that includes the necessary piping system and control system. Typical.

An example of a sanitary cleaning device having such a configuration is described in Japanese Patent Publication No. 13450/1983. This has a cleaning water piping system and a heating system in a casing integrated with the toilet body, and is also provided with a nozzle that is advanced to the cleaning position by an electric motor.

By the way, the supply amount of washing water per unit time required for private part washing is relatively small, and the flow rate is generally smaller than the insensitive water amount specified by the waterworks bureau. For this reason, it is necessary to make the amount of water during washing larger than the insensitive water amount, and it is necessary to send in the amount of water necessary for washing and discard the excess water.

In order to dispose of such water, a washing water supply system shown in FIG. 8 has conventionally been adopted. This includes a valve unit 51 in the cleaning water supply system to the nozzle 50, a heating tank 52 downstream of the valve unit 51, and a drainage channel 5 in the agent system.
3 are connected. The valve unit 51 is supplied with water from an external water supply source at a flow rate larger than the insensitive water amount, and distributes the necessary amount to the nozzle 50 side, and sends excess water to the drainage channel 53. As a result, the water passing through the water meter provided upstream of the valve unit 51 is thicker than the insensible water volume, and the installation satisfies the regulations of the Waterworks Bureau.

In addition, by discarding the cold water in the pipes before cleaning begins,
In order to be able to supply washing water at an appropriate temperature when washing private parts, it was necessary to install a drainage system.

[Problem to be solved by the invention]

However, the drainage channel 53 is provided separately from the route to the nozzle 50 side, and is generally led to the opening of the casing by, for example, a hose. Therefore, it is necessary to connect a hose to the valve unit 51 and to install piping through the built-in equipment, which takes time and effort to assemble.

Further, since a space and a member are required for fixing the hose to the opening of the casing, this is one of the causes that hinders the freedom of layout of various devices to be incorporated into the casing.

Therefore, an object of the present invention is to simplify the assembly by integrating the nozzle side and water waste side systems into one system, and to enable even more effective use of the inside of the casing.

[Means to solve the problem]

In order to achieve the above object, the present invention provides two systems of cleaning water channels inside a nozzle rod that strokes between a storage position and a cleaning position, and connects each of these two systems of cleaning water channels. The sanitary washing device is equipped with a communicating jet hole at the tip of the nozzle rod, and is characterized in that the nozzle rod is provided with a third flow path and the flow path is connected to a waste water system.

This drainage channel 7 is the drainage channel 2c of the nozzle rod 2.
The water is finally discharged from the drain hole 2g.

In this way, since the water waste channel 2c is also formed in the nozzle rod 2, there is no need to pipe a hose or the like for water waste to a position facing the bowl of the toilet main body A. Therefore, compared to the conventional structure in which a drainage pipe or the like is placed near the nozzle device 1, the space around the nozzle device 1 can be made cleaner. Therefore, the space for installing wastewater pipes and the like can be used for accommodating other equipment, and the limited space inside the casing B can be used effectively.

In this way, it is easy to manufacture by using a vibrator, and if you store these vibrators separately and fill the inside with insulation material 2h, you can create a cooling water flow path 2c through which unheated water flows. Even if it is included in the nozzle rod 2, the first
．． It is possible to prevent the temperature of the cleaning hot water flowing through the second flow paths 2a and 2b from decreasing.

〔Effect of the invention〕

As explained above, in the sanitary washing device of the present invention, the nozzle rod of the nozzle device is equipped with a waste water flow path, which is necessary to prevent the amount of insensitive water and for discharging cold water before the start of washing, to supply washing water. At the same time, excess water is being drained away. Therefore, compared to the conventional structure in which the drain pipe is piped to a position facing the bowl part of the toilet main body, such piping is partially omitted, and the space around the nozzle device can be used effectively. Furthermore, conventional drainage pipes have been fixed using fixing fittings, positioning pieces provided on the casing, etc., but in the present invention, it is only necessary to connect them to the nozzle rod, making assembly easy.
