2. Description of the Related Art A sanitary washing device is provided with a hot-water type washing water tank or an instantaneously-boiled washing water tank inside a casing having a toilet seat and a toilet lid that can be opened and closed, and washing from these tanks via a valve unit. The basic configuration is to send cleaning water to a nozzle for use. The valve unit is controlled by a controller, and includes a strainer, a pressure regulating valve for adjusting pressure, a main valve, and the like, and is disposed upstream of the tank. A valve such as a main valve opens and closes a flow path as a solenoid valve, and a housing of the solenoid valve is mounted on a main body of the valve unit.
In a conventional sanitary washing device, the solenoid valve is generally equipped with a diaphragm valve integrally.

[0003]

However, if the solenoid valve and the diaphragm valve are integrally mounted, if the solenoid valve is to be replaced when it is out of order, the diaphragm valve must also be separated, and the replacement work is required. It takes time and effort. Also,
Depending on the installation position of the valve unit, the solenoid valve may be arranged downward. In this case, the valve unit itself must be removed and the solenoid valve must be replaced.

[0004] Therefore, an object of the present invention is to provide a sanitary washing device in which the replacement of the solenoid valve of the valve unit can be easily performed.

[0005]

According to the present invention, a valve unit connected to an external water supply source is disposed in a space formed by a base and a casing, and a heat exchanger is provided downstream of the valve unit. And in a sanitary washing device in which a nozzle device for local washing is connected downstream of the heat exchanger, an electromagnetic valve attached to the valve unit,
The arrangement is such that the casing is exposed to the outside when the casing is opened.

Another feature is that an electromagnetic valve is arranged on the upper surface or the peripheral side surface of the valve unit.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS In the present invention, an arrangement is such that when a casing is opened, a solenoid valve attached to a valve unit is exposed to the outside. For this reason, it is possible to easily perform the replacement work by removing only the solenoid valve, thereby simplifying the maintenance and inspection work.

Further, in the case where the solenoid valve is arranged on the upper surface or the peripheral side surface of the valve unit, the tool can be hung from above or from the side and can be detached and attached, so that the work becomes easier.

Downstream of the strainer 23, a check valve 40 and a pressure regulating valve 25 for reducing the supply pressure of water are arranged. Downstream of the pressure regulating valve 25, a flow path 21a directed to the right is formed as shown in FIG.
The main valve body 26a is disposed at the end of the flow path 21a. The main valve body 26a is driven to open and close by a main solenoid valve 26 disposed outside the main body 21. From the flow path 21a between the pressure regulating valve 25 and the main valve body 26a, a flow path (not shown) supplied for nozzle cleaning is branched as shown in FIG. A sub solenoid valve 27 is arranged in the branched flow path, and the sub solenoid valve 2 is operated by a signal from a controller (not shown).
The valve element of No. 7 opens and closes, and supply and stop of nozzle cleaning water are performed from the nozzle cleaning discharge pipe 28 connected to the branched flow path. The main solenoid valve 26 and the sub solenoid valve 27 are fixed to the main body 21 of the valve unit V by screws (described later).

FIG. 8 is an exploded perspective view showing the valve unit V and a metal fitting for fixing the valve unit. FIG. 9 is a bottom view when the metal fitting is integrated.

The main body 21 of the valve unit V has a substantially L-shaped planar shape, and is fixed on the base 1 so that the joint 22 and the pressure regulating valve 25 face downward. Then, as shown in FIG. 4, the sub solenoid valve 27 is provided in the flow path branched on the upstream side of the main solenoid valve 26, so that the sub solenoid valve 27 is located above the main body 21 as shown in FIG. The main solenoid valve 26 is located on the front side of the base 1 as shown in FIG. That is, depending on the flow path configuration of the valve unit V, the sub solenoid valve 27 and the main solenoid valve 26 are located at different positions,
1 can be arranged on the upper surface side and the front side.

The valve unit V is fixed to the base 1 with screws by combining the rotation stopper 6 and the fixing member 7. That is, the detent fitting 6 having the hexagonal opening 6a is fitted and fitted to the hexagonal flange 22a formed on the joint 22, and the fixing fitting 7 is sandwiched by the four screws 7a with the detent fitting 6 interposed therebetween. The unit V is integrated as shown in FIG. The main body 21 of the valve unit V has a substantially L-shaped planar shape, and is fixed to the base 1 by connecting the detent member 6 and the fixing member 7 on the joint 22 side. On the other hand, as shown in FIG. 10, the base 1 is provided with three fixed seats 1a with cylindrical openings for fixing the valve unit V. And
Screw holes 6b are provided in the detent metal fitting 6 so as to coincide with these fixing seats 1a. Therefore, the valve unit V is screwed into the opening of the fixed seat 1a by screwing the screw 6c (see FIG. 8) passing through the screw hole 6b, whereby the valve unit V shown in FIGS.
Is fixed in the posture shown in FIG.

Incidentally, a ground wire 8 is connected to the fixing bracket 7. The main solenoid valve 26 and the sub solenoid valve 27 are fixed to the main body 21 of the valve unit V by screws 26b and 27a, respectively.

In the above configuration, if the casing 2 is removed from the base 1, the valve unit V appears as shown in FIGS. The main solenoid valve 26 is connected to the front side of the main body 21 of the valve unit V and the sub solenoid valve 27.
Is exposed on the upper surface side of the main body 21. For this reason, when removing the main solenoid valve 26, screw the driver 26 from the front side.
The main solenoid valve 26 can be easily removed from the main body 21. Similarly, the auxiliary solenoid valve 27 can be easily removed by attaching a screwdriver to the screw 27a from the upper surface side. When the main solenoid valve 26 and the sub solenoid valve 27 are replaced with new ones, the main solenoid valve 26 and the sub solenoid valve 27 can be easily fixed to the main body 21 of the valve unit V by working from the front side and the top side, respectively.

As described above, when the casing 2 is removed, the main solenoid valve 26 and the sub solenoid valve 27 are exposed on the surface. By turning the respective screws 26b and 27a, the main solenoid valve 26 and the sub solenoid valve can be easily connected. The valve 27 can be exchanged.

The main body 21 of the valve unit V is cantilevered on the joint 22 side by a rotation stopper 6 and a fixing member 7. In such a fixing structure of the main body 21 of the valve unit V, the valve unit V can be supported by the reaction force receiving when connecting the water supply pipe from the outside to the joint 22, the detent fitting 6 and the fixing fitting 7. Can be stably supported. The main solenoid valve 26 and the sub solenoid valve 27 are connected to the joint 2
Since the main solenoid valve 26 and the sub solenoid valve 27 are operated at a position distant from the base 2, a signal when the main solenoid valve 26 and the sub solenoid valve 27 operate is less likely to be transmitted to the base 1 side, thereby enabling a quiet operation.

[0028]

According to the first aspect of the present invention, the solenoid valve attached to the valve unit is exposed to the outside when the casing is opened, so that only the solenoid valve can be replaced without any change. The operation of replacing the solenoid valve is simplified as compared with the configuration in which the diaphragm valve is mounted on the solenoid valve.

According to the second aspect of the present invention, since the solenoid valve is disposed on the upper surface or the side surface of the valve unit, the work of attaching and detaching the solenoid valve can be more easily performed than when the solenoid valve is provided below the valve unit. be able to.
