In the state of FIG. 3, the multi-valve 25 is switched from the circulation drainage port 4b to the external drainage port 4c, so that the filter medium in the filter tank 14 is bathed. After washing with, the water can be drained to the outside from the drain port 4c.

Next, an example of a method for mounting the circulation device body 2 on the mounting base 3 will be described. First, a free insertion hole 8 is formed at a position corresponding to the pipe connection portion 6 of the mounting base 3 shown in FIG. 1 so that the lower portion 6b of the pipe connection portion 6 of the installation base 7 is inserted into the free insertion hole 8. The mounting table 7 is placed on the mounting table 3, and the mounting table 7 is fixed to the mounting table 3 with the screw 21, and the water supply pipe 5 for the bathtub 5
Each end portion of a, the circulation drainage pipe 5b, and the external drainage pipe 5c is fitted and connected to the outer peripheral surface of the lower portion 6b of the corresponding pipe connection portion 6, respectively. At this time, the circulation device body 2 is placed on the installation stand 7.
Has not yet been installed, and the lower portion 6b of the pipe connection portion 6 of the installation table 7 can be smoothly inserted into the free insertion hole 8 of the installation table 3, and the screw 21 can be inserted without being disturbed by the circulating device body 2. Since the mounting table 7 can be fixed to the mounting table 3 by means of, the mounting work of the mounting table 7 on the mounting table 3 can be easily performed.

After that, the connecting straight pipe portions 9 projecting downward from the bottom portion 2a of the circulating device main body 2 are aligned with the respective pipe connecting portions 6 of the mounting base 7, and the circulating device main body 2 is mounted on the mounting base 7. Simply insert it on the insert section 9a at the tip of each straight pipe section 9 for connection.
Is fitted to the inner surface side of the upper portion 6a of each pipe connecting portion 6, and at the same time, the tapered taper surface (sealing means 10) provided on the outer surface of the inserting portion 9a is brought into close contact with the inner surface of the upper portion 6a of the pipe connecting portion 6. Thus, the connecting straight pipe portion 9 and the pipe connecting portion 6 are in a sealed state. Then, the bottom portion 2a of the circulation device body 2 and the installation table 7
And a screw portion 11 formed on the outer surface of the upper portion 6a of the pipe connection portion 6 by rotating a cap nut 12 rotatably and rotatably provided on the upper portion of the connecting straight pipe portion 9 The straight pipe portion 9 for connection and the pipe connecting portion 6 can be fixed by sealing by screwing into the main body 2 of the circulation device.
The installation base 7 can be securely fixed.

In this way, the water supply / drainage port 4 of the circulating device body 2 is connected to the connecting straight pipe portion 9 only by placing the circulating device body 2 on the installation table 7 and rotating the cap nut 12.
It becomes possible to directly connect to the water supply / drainage pipe 5 with one-touch through the pipe connection part 6 and the pipe connection portion 6, and it is not necessary to perform a troublesome work such as inserting a hose in a narrow space between the circulation device body and the mounting base unlike the conventional case. It is possible to easily and smoothly attach the circulation device 1. Moreover,

The mounting bolt 33 provided on the bottom portion 2a of the circulation device main body 2 can be operated via the connector. This makes it easy to rotate the mounting bolt 33, and the connecting shaft 37 penetrates through the circulation device main body 2. However, there is an advantage that the circulation device main body 2 can be easily and visually installed on the installation stand 7 without being visible from the outside.

In the embodiment of FIG. 9, instead of the structure including the mounting bolt 33, the mounting bolt operating portion 36 and the connecting shaft 37 of FIGS. 7 and 8, a lock groove 40 protrudingly provided on the upper surface of the installation base 7 is used. The protrusion 41 and the ring-shaped rotating plate 44 having a lock piece 43 that is rotatably attached to the rotation supporting portion 42 provided on the upper surface of the bottom portion 2a of the circulation device body 2 and has a lock piece 43 that can engage with the lock groove 40. The mounting means 30 is configured.
Here, a guide groove 45 extending vertically is formed on the outer peripheral surface of the protrusion 41.
The upper end of the guide groove 45 is open upward, and the lower end of the guide groove 45 is connected to the upper end of the lock groove 40 inclined obliquely downward. Rotating plate 4
A lever 50 protruding from a laterally elongated slit 60 formed in the outer peripheral surface of the circulation device body 2 is connected to the valve 4, and the lever 50 can be operated in a direction to engage the lock piece 43 with the lock groove 40. .

Therefore, when the circulating plate 44 and the protrusion 41 are aligned and the circulating device body 2 is placed on the installation table 7, the lock piece 43 of the rotating plate 44 is slid and inserted from the upper end of the guide groove 45 of the protrusion 41. Then, the entire projection 41 is inserted into the central hole 44a of the rotary plate 44, and the bottom portion 2a of the circulation device body 2 can be placed on the installation table 7. In this state, when the lever 50 is rotated in the lock direction A, the rotary plate 44 is rotated. Lock piece 43 is guide groove 4
It is possible to enter the lock groove 40 continuously provided at the lower end of 5. Since the lock groove 40 is inclined obliquely downward, as the amount of rotation of the lever 50 increases, the protrusion 41 is lifted upward with respect to the rotating plate 44, and the lock device 40 and the circulation device main body 2 move in the direction of the arrow in FIG. 9D. A force is generated to bring the installation base 7 into close contact, and the circulation device body 2 can be fixed to the installation base 7 with one touch without using bolts or screws.
Moreover, by providing the lever 50, there is an advantage that the fixing work can be easily performed without a tool even in a place where it is difficult to reach, such as the inside of the circulation device body 2.
