Description

DETAILED DESCRIPTION OF THE INVENTION A. Industrial Field of Application The present invention is directed to a method for pumping up bath water in a bathtub through a suction pipe using a circulation pump, filtering the bath water through a filter, and returning the bath water through a discharge pipe to the bathtub. The present invention relates to a bath water circulation purification device including a purification unit, for example, to a device that circulates and purifies bath water in a domestic bathtub.

B. Summary of the Invention The present invention provides a bath water circulation purification device comprising a bath water purification unit that pumps up bath water in a bathtub via a suction pipe with a circulation pump, filters it with a filter, and returns it into the bathtub via a discharge pipe. , a second filter having a coarser mesh than the filter in the bath water purification unit is disposed in a midway portion of the suction pipe and located in the bathtub; A third filter member having a coarser mesh than the second filter is disposed in the suction port portion, and bath water in the bathtub is pumped up by the circulation pump through the plurality of filters disposed on the suction pipe. By doing so, the purification ability is increased and the main filter provided in the bath water purification unit in the main body of the apparatus can be used for a long period of time.

C. Prior Art Conventionally, devices that purify the bath water in household bathtubs so that they can be used for a long period of time have been proposed, for example, in Japanese Utility Model Application Publication No. 63-69517 and Japanese Utility Model Application Publication No. 64-12611. As disclosed in , there is provided a bath water circulation purification device in which bath water in a bathtub is pumped up via a suction pipe by a circulation pump, filtered by a filter, heated by a heater, and returned to the bathtub via a discharge pipe. It's been done.

Filters for filtering bath water in bath water circulation purification devices include sheet filters using filter paper as the filter member, porous filters using porous resin or porous ceramics, and filters made of maifan stone, sun stone, etc. A combination of granular filters made of natural stones (so-called mineral stones) packed in a container is used as a filter member.

In addition, generally, in such a bath water circulation purification device, a coarse primary filter called a so-called hair cancher is installed at the inlet of the suction pipe to remove relatively large dust such as hair mixed in the bath water. The bath water in the bathtub is pumped up by a circulation pump through this primary filter.

D Problems to be Solved by the Invention By the way, in a bath water circulation purification device, bath water in a bathtub is pumped up via a suction pipe by a circulation pump, filtered by a filter, and returned to the bathtub via a discharge pipe. If the function deteriorates, it becomes impossible to obtain the purifying effect of bath water, so it is necessary to frequently replace the filter.

Generally, it is not only difficult to replace the main filter installed in the bath water purification unit 7 of the main body of the device, but also
If air enters the bath water circulation path when the main filter is replaced, there is a large possibility of an accident in which the bath water circulation function by the circulation pump does not work properly.

In addition, conventionally, a coarse primary filter called a hair catcher that removes relatively large dust such as hair mixed in the bath water has been installed at one inlet of the solo vibrator. Although the bath water in the bathtub is pumped up by a circulation pump through a filter, the function of the main filter installed in the bath water purification unit of the main body of the device may be shortened due to the dirt that passes through the primary filter. The reality is that it declines over time.

In view of the above-mentioned conventional problems, the present invention aims to purify the bath water by pumping up the bath water in the bathtub through the suction pipe with a circulation pump, filtering it with a filter, and returning it into the bathtub through the discharge pipe. It is an object of the present invention to improve the purification ability of a bath water circulation purification device equipped with a bath water purification unit, and to enable long-term use of a main filter provided in a bath water purification unit within the device body.

In order to achieve the above-mentioned object, the present invention pumps bath water in a bathtub through a suction pipe with a circulation pump, filters it with a filter, and pumps it into the bathtub through a discharge pipe. In the bath water circulation purification device including a bath water purification unit that returns the water to water, a portion located in the bathtub that is a midway portion of the suction pipe,
A second filter with a coarser mesh than the main filter in the bath water purification unit is disposed, and a second filter with a coarser mesh than the second filter is disposed in the suction port of the suction pipe located in the bathtub. 3 filters are arranged, and bath water in the bathtub is pumped up by the circulation pump through the plurality of filters arranged in the suction pipe.

F Function In the bath water circulation purification device according to the present invention, the bath water in the bathtub is pumped up by the circulation pump while being filtered through a plurality of filters arranged on the suction pipe, and further filtered by the main filter in the bath water purification unit.

The filter disposed on the suction pipe is easy to replace, and since it is located within the bath water of the bathtub, it is inevitable that air will enter the bath water circulation path during replacement.

G. Example Hereinafter, examples of the bath water circulation purification device according to the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the basic structure of the bath water circulation purification device according to the present invention is such that bath water (2) in a bathtub (1) is circulated by a circulation pump (3) through a suction pipe (4). It is pumped up, filtered through the main filter (5), and sent to the discharge pipe (
6) to return the bath water into the bathtub (1) via the bath water purification unit)
(10) A bath water circulation purification device comprising second and third filters (11) in the suction pipe (4),
(12) is arranged.

The second filter (11) is coarser than the main filter (5) in the bath water purification second unit (10), and is located in the bathtub (1) of the suction pipe (4). It is placed in the middle of the process.
