Description

[Detailed description of the invention] The present invention is a private parts washer, more specifically, a private parts washer that has a washing nozzle that squirts hot water to wash the private parts such as the anus, and an auxiliary nozzle that washes the rim surface of the toilet bowl, etc., and has a flow rate adjustment device. Regarding equipment.

Conventionally, when using a private area washer that is directly connected to a water supply source such as a tap water supply, when adjusting the flow rate to adjust the amount of water spouted from the cleaning nozzle according to the user's preference, the adjustment method as shown in Figure 3 or Figure 4 is used. This was done by adjusting the opening and closing of the pressure valve 3 or needle valve 4.

However, when the needle valve 4 is used, there is a problem in that when the water pressure of the water supply source 1 changes, the water pressure on the secondary side changes and the amount of water discharged from the cleaning nozzle 6 and the auxiliary nozzle 7 changes. .

In addition, when the pressure regulating valve 3 is used, it is possible to keep the water pressure on the secondary side constant in response to fluctuations in the water pressure of the water supply source 1, but if the flow rate is adjusted with the pressure regulating valve 3, it is not possible to The amount of water spouted by the auxiliary nozzle 7, which should be a constant amount, increases and decreases in conjunction with it, while in FIG. There was a problem.

Therefore, the purpose of this invention is to solve these problems and to make it possible to obtain a constant amount of water from the auxiliary nozzle, even if the water supply pressure fluctuates or the amount of water from the cleaning nozzle is adjusted. That is.

The basic structure of the present invention is to provide both a pressure regulating valve and a needle valve, branch the downstream side of the pressure regulating valve, connect one to the cleaning nozzle via the needle valve, and assist the other without going through the needle valve. With this configuration, a part of the cleaning water whose pressure is kept constant by the pressure regulating valve is sent to the cleaning nozzle after adjusting the flow rate, and the rest is sent to the auxiliary nozzle.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, a is a cleaning water supply line that connects the water supply source 1 such as tap water and the cleaning nozzle 6, and the water supply line a
, an on-off valve 2, a pressure regulating valve 3, a needle valve 4, and a heat exchanger 5 are arranged in sequence on the downstream side of the water supply source 1, and are connected to the cleaning nozzle 6; This is an auxiliary water supply line that communicates with the auxiliary nozzle 7 without going through the valve 4.

The on-off valve 2 is an electromagnetic on-off valve, and when the valve 2 is energized, a flow path formed inside the valve is opened and closed. Note that the on-off valve 2 may be a manual on-off valve.

The pressure regulating valve 3 is provided with a valve body that is constantly pressed in the direction of the valve seat hole by a spring.
Even if the water pressure on the downstream side changes naturally, the valve body moves slightly due to the urging force of the spring to maintain the water pressure on the secondary side of the valve 3 constant.The downstream side of this pressure regulating valve 3 is branched, One side is connected to the cleaning nozzle 6, and the other side is connected to the auxiliary nozzle 7.

The needle valve 4 adjusts the flow rate by fitting a valve body with a tapered surface into the valve seat hole to change the passage area, and is provided downstream of the pressure regulating valve 3 in the water supply line a communicating with the cleaning nozzle 6. .

The heat exchanger 5 heats the wash water to a set temperature by inserting a rod-shaped ceramic heater into a hollow tank.

The cleaning nozzle 6 sprays cleansing water onto the private parts of the user sitting on the toilet seat from a spout provided at its tip, and branches downstream of the pressure regulating valve 3 and connects to the water supply line a via the needle valve 4. establish.

The auxiliary nozzle 7 cleans the rim surface of the toilet bowl, the above-mentioned cleaning nozzle 6, etc. through a spout provided at its tip, and is branched downstream of the pressure regulating valve 3 and provided in the auxiliary water supply line b without passing through the needle valve 4.

In addition, the auxiliary nozzle 7 discharges water into the toilet bowl at a rate equal to or greater than the flow rate difference between the standard value of the insensitive water amount specified by the Japan Water Works Association and the amount of water discharged from the cleaning nozzle 6, thereby moving the toilet out of the insensible water amount range. .

The flow rate ejected from the cleaning nozzle 6 is adjusted to a constant water pressure by the pressure regulating valve 3, and then the needle valve 4
It is increased or decreased by On the other hand, the cleaning water discharged from the auxiliary nozzle 7 is only pressure regulated by the pressure regulating valve 3 and is not interlocked with the needle valve 4.

In the above embodiment, on the other hand, the heat exchanger 5
Although the pressure regulating valve 3 and the auxiliary nozzle 7 are directly connected to each other, and the pressure regulating valve 3 and the auxiliary nozzle 7 are directly connected to each other, the present invention is not limited to this. Vacuum breakers 8 may be provided to prevent backflow when a negative pressure is generated on the upstream side between the pumps and the pumps 7, respectively.

Since the present invention has the above configuration, it has the following advantages.

The cleaning water discharged from the cleaning nozzle and auxiliary nozzle is regulated to a constant water pressure by a pressure regulating valve.
Even if the water pressure of the water supply source fluctuates, a stable amount of water can be obtained regardless of this.Moreover, a portion of the cleaning water branched downstream of the pressure regulating valve is communicated to the cleaning nozzle via the needle valve, so the needle valve Therefore, even if the amount of water discharged from the cleaning nozzle is adjusted according to the user's preference, the auxiliary nozzle is not linked to the needle valve and a constant amount of water can always be ensured.

Since the water pressure downstream of the pressure regulating valve is stabilized, the operation of the needle valve, heat exchanger, cleaning nozzle, and auxiliary nozzle is stabilized, allowing comfortable cleaning and improving durability.
