Description

Description: TECHNICAL FIELD The present invention provides a cleaning liquid filter for purifying dirt and a chemical liquid supply unit for sterilizing bacteria and the like that grow after bathing, as well as providing a jet flow to bath water in a bath. The present invention relates to a bath circulation device.

2. Description of the Related Art Conventionally, in this type of bath circulation device, as shown in FIG. 3, a circulation circuit is constituted by a circulation pump 2 which circulates bath water 1 and a purifying filter 3, and an air vent valve is It was located at the highest position in the circulation circuit or was not provided in most cases.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above-described configuration, air is apt to accumulate in the inside of the filter whose cross-sectional area is usually larger than that of the circulation circuit, which causes noise due to air biting inside the filter. When an air bleed valve is installed in the circulation circuit, the circulating water is dirty bath water containing impurities, so the valve seal part of the air bleed valve often becomes dusty and malfunctions within a short time. Had a problem.

The present invention solves the above-mentioned conventional problems. It prevents air biting inside the filter, suppresses noise generation, and does not cause dust bite in the valve seal portion of the air bleeding valve even in a dirty bath water circulation circuit. The purpose is to obtain a circulation device for use.

Means for Solving the Problems In order to solve the above problems, in the bath circulation device of the present invention, a plurality of filter media are arranged in the filter above the air bleeding valve and inside the filter, and one of them is provided. 2 of the filter material
The structure is provided on the secondary side, that is, at a position after the circulating water has been purified, that is, at the inner upper part of the filter medium.

Action According to the present invention, since a plurality of filtration media are arranged by the above-described configuration, the flow velocity of the circulating water inside each filtration media is reduced, the air bubble separation is promoted, and the separated air bubbles become a flow. You can easily move upside down. Further, the inner upper part of the filter medium is not easily affected by the flow of the circulating water, and the separated air bubbles gather at the upper part and become almost stationary. Therefore, the air can be easily discharged to the outside by the air vent valve. In addition, since the air vent valve is provided after the circulating water is filtered and purified, even if it is used for a long period of time, no dust bite or the like will occur in the valve seal portion.

Embodiments Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 is bath water, and a circulation pipe 7 connects a circulation pump 2 and a purification filter 3 to form a circulation circuit. On the other hand, a sterilizing chemical solution tank 4, a chemical solution 5 and a chemical solution supply pump 6 are arranged in the case 8, and the chemical solution 5 is injected into the filter 3 via a check valve 9 for preventing backflow of bath water. A chemical hose 10 is provided.

On the other hand, FIG. 2 is a detailed cross-sectional view of the filter 3 for purification according to the present invention, in which a plurality of filter media 13 are sandwiched between the body 11 and the upper lid 12, and the outer cylinder 14 constitutes an outer frame. There is. The filter material is not particularly specified as long as it can filter impurities such as a wound type filter and a ceramic filter, and the shape is not limited to a cylindrical shape, and may be a vertically long and cylindrical shape through which circulating water is filtered.

The body 11 is provided with an inlet 15 for circulating water provided on the side surface, an inlet 16 to the inside at approximately the center, and an outlet 17 for circulating water passing through the filter medium 13. The upper lid 12 is provided with a chemical solution inlet 18 and an air vent valve 19 at a position facing the inlet 16 at approximately the center. The air vent valve 19 is provided on the secondary side after the circulating water is filtered at the upper part of one of the plurality of filter media, that is, on the inside of the filter media.

Explaining the operation in the above configuration, the bath water 1 flows inside the circulation pipe 7 by the operation of the circulation pump 2, and impurities are formed on the outer peripheral surface (primary side) of the filter medium 13 in the purification filter 3 disposed midway. The circulating water, which has been filtered and purified, flows to the inner surface of the filter medium and is then jetted from the outlet 17 to the bath 1.

Further, the chemical solution 5 in the chemical solution tank 4 is pressurized by the chemical solution supply pump 6, passes through the chemical solution hose 10, and is injected from the chemical solution injection port 18 into the primary side of the filter material 13 in the filter 3. When the bather presses the operation switch (not shown) after bathing, the circulation pump 2 is activated first, and then a certain amount of the medicinal liquid is injected, so that the concentration of the sub-liquid in the bath water is about 1 ppm. Keep at and sterilize germs. The check valve 9 prevents the backflow of the circulating water to the chemical liquid tank 4 due to the water pressure inside the filter 3,
Further, the air vent valve 19 discharges the air accumulated in the filter 3 to the outside of the filter 3, and since only the purified circulating water that has passed through the filter medium 13 comes into contact with the air vent valve 19, the operating portion of the air vent valve 19 In particular, the valve seal portion does not cause a water leakage problem or the like due to dust.

As described above, in the above structure, since the air vent valve is arranged above the filter, noise is not generated due to air biting inside the filter, and the air vent valve only touches the circulating water after being purified by the filter medium. Since it does not have a valve seal portion, it is possible to obtain a bath circulation device without malfunction.

Effects of the Invention As described above, according to the bath circulation device of the present invention, a plurality of filters for bath water purification are arranged in parallel, the outer peripheral surface of the filter is used as an impurity trapping surface, and the innermost top portion of the filter is used. Since it is equipped with an air bleed valve, it is easy to bleed air and no noise is generated. Also, the air bleeding valve is a filter 2
Since it is provided on the secondary side, there is no malfunction of the air bleeding valve.
