[0007]

The conventional water purifier described above has a complicated structure in which a large number of Miranel stones (purifying material) are contained in a cylindrical container and are pressed by a dropping lid. It is cumbersome to handle, and when washing the Miranel stone for reuse, it is not possible to wash the entire container. In addition, since a drop lid is required, warm water (bath water) can be provided by this drop lid.
A large resistance works, and the purification action becomes small. This means that in the case of a water purifier using a plurality of types of Miranel stones and having a plurality of stages of cleaning units, an inner lid is required between each water purification unit, which is a serious problem of a decrease in the cleaning action. The strength of the purifying action is proportional to the relative speed between the warm water and the purifying material. Furthermore, since the cap member and the spacer (coil spring) are separate, operability and maintenance are difficult. As a result, the hot water circulation device for a bathtub equipped with such a water purifier has low reliability.

The present invention has been made in view of the above-mentioned problems of the prior art. It is easy to handle the purifying material, the purifying material can be washed with water in each net bag, and the purifying action and maintainability are improved. An object of the present invention is to provide a water purifier and a hot water circulation device for a bathtub including the water purifier.

In the invention described in claim 1, a net bag containing a large number of pellet-like purifying materials is put into the inner container through the opening of the water purifier body, and the pressing means is placed in the opening of the water purifier body. It is attached and the mesh bag is pressed to immobilize the purifying material therein. In this state, when water is passed through the water purifier body, there is no drop lid, so the flow resistance is small, and this water passes through the gap of the purification material and is purified. To wash the purifying material with water for reuse, take out the purifying material from each inner container and wash the whole purifying material with water. Further, since the purifying material is housed in the net bag all at once, the conventional dropping lid is not necessary. In the invention according to claim 2, since the elastic member is provided integrally with the lid member attached to the water purifier body, the mesh bag can be taken out from the inner container simply by removing the lid member from the water purifier body. .

The bath water filtered by the pre-filter 6 fills the pre-filter 6 and then gradually leaches out from the lower end surface of the pre-filter 6 by the action of gravity and the bath water circulation pump 11. The bath water that has leached fills the space 26, and gradually moves inward in the radial direction from the outer peripheral surface of the bobbin filter 4 due to the internal pressure of the filled bath water and the action of the bath water circulation pump 11. It flows from the inner peripheral surface into the hollow portion 4a. As a result, micron-order suspended matter in the bath water is collected on the outer peripheral surface of the bobbin filter 4 and in the bobbin filter 4, and the hollow portion 4a
Bath water, which contains almost no suspended solids, flows into this.

The bath water flowing into the hollow portion 4a reaches the inside of the bath water circulation pump 11 through the primary intermediate pipe 10 by the action of the bath water circulation pump 11, and further passes through the secondary intermediate pipe 12 and the inflow port 15a to be purified water. Flows into the container 18. This inflowing water is a clean bath water having almost no germs and contaminants, due to the sterilizing action of the purifying materials 23b and 23a enclosed in the net bags 20 and 19 in the water purifier 18, and the openings 13a and the protrusions. The space gradually overflows into the space 27 from between the portions 13b. The overflowed bath water is subjected to gravity and the action of the bath water circulation pump 11,
It is gradually collected in the bathtub through the outlet 15b and the water outlet pipe 3.
