A large number of 43h holes are drilled at a fixed pitch (for example, 7 mm) to provide water permeability.The filter material 43c is extremely small compared to the through hole 43h, so the through hole 43h is closed by the bridge phenomenon of the filter material 43c. I try not to.

As shown in FIGS. 3 and 5, a suction pipe connecting portion 41a and an exhaust pipe connecting portion 28a are provided on the side surface of the upper end portion of the filter body 43a, and as shown in FIG. 41a is connected to the upper impeller chamber 33 of the circulating pump P via the inlet pipe 41, and the exhaust pipe 28 is connected to the exhaust pipe connecting part 28a to communicate the upper part of the filter body 43a with the water supply pipe 12 to perform the filtration. A return pipe connecting portion 42a is provided on the side surface of the lower end portion of the machine body 43a, and the connecting portion 42a is connected to the water supply pipe 12 through the return pipe 42.

As shown in FIGS. 3 and 4, the inlet pipe connecting portion 41a, the exhaust pipe connecting portion 28a, and the return pipe connecting portion 42a each have a shaft center Fo of a filter body 43a whose opening direction is substantially cylindrical. Eccentric to the left from the filter body 43
A swirling flow N is generated in the bath water within a.

As shown in FIG. 2, the electric three-way valve 37 is connected to the middle of the retraction pipe 41, and two of the three pipe connections of the three-way valve 37 are connected to the retraction pipe 41. ,
One end of the drain pipe 46 is connected to the remaining one pipe connection part.

With the above configuration, the hot water from the upper impeller chamber 33 is caused to flow downward from above in the interior of the filter main body 43a by switching the flow path of the electric three-way valve 37, thereby forming the support net 43b. Filtration pressure is applied to the bead-shaped filter medium 43c supported on the upper surface to form a filtered structure, and foreign matters mixed in the bath water while the bath water passes through the structure can be filtered out.

Further, by switching the flow path of the electric three-way valve 37,
Backwashing of the filter medium, that is, the upper part of the filter body 43a is communicated with the drain pipe 46, and the bath water from the lower impeller chamber 34 of the circulation pump P is filtered through the water supply pipe 12 and the return pipe 42. It is introduced into the lower part of the main body 43a and is caused to flow upward in the main body 43a of the filter, whereby the filter tissue is broken and the bead-like filter medium 43c is moved between the upper surface of the support net 43b and the lower surface of the lower baffle plate 43f. The filter cake is made to flow, and the filter cake deposited or attached to the filter medium 43c is washed, and can be discharged to the outside from the drain pipe 46.

The upper and lower baffle plates 43d and 43f are stretched above the 43c while maintaining a space of a predetermined volume, so that a total of two baffle plates are arranged in series with respect to the flow of bath water, and By generating a swirling flow in the hot water in the filter body 43a, during normal hot water filtration, the flow of the hot water is rectified and the flow speed of the hot water becomes uniform in each part, so that the filtering medium 43c is removed. Soaring can be suppressed.

Further, the bath water flowing into the filter body 43a from the inlet pipe connecting portion 41a turns clockwise when viewed from above, and even if the filter medium 43c soars into the bath water, the opening direction is not changed. To the exhaust pipe connecting portion 28a which is eccentric to the left from the shaft center Fo,
Since the swirling flow N hits obliquely from behind, the filter medium 43c that has flown up due to the flow of the bath water is prevented from flowing out of the exhaust pipe connecting portion 28a.

When the filter medium is washed, the two baffle plates 43d and 43f equalize the flow rate of the backflow of the bath water in the upper portion of the filter body 43a, and are sufficient for washing the filter medium 43c from the return pipe connecting section 42a. Even if the bath water having a high flow rate is supplied to the lower part of the filter body 43a, the excessive flow of the local filter medium 43c is prevented, so that the filter medium 43c is prevented from flowing out from the connecting pipe connecting portion 41a. Can be.

When the filter medium is washed, the exhaust pipe connecting portion 28
Since a is in communication with the water supply pipe 12, it has the same pressure as that of the return pipe connecting portion 42a, thereby preventing the filter medium 43c from flowing out therefrom.

As described above, the upper and lower baffle plates 43d, 43
f and the opening direction of each pipe connecting portion 41a, 28a, 42a is eccentric from the axis Fo of the filter main body 43a, so that the filter main body 43a
