2. Description of the Related Art In recent years, a circulating warm bath called a so-called 24-hour bath has been widely used. As shown in FIG. 10, such a circulating hot water bath is a hot water bath including a bath water suction unit 2, a bath water supply unit 3, and a filter cylinder and a pump for purifying and heating the bath water between the bath water suction unit 2 and the bath water supply unit 3. It consists of a container body 4. The warm bath main body 4 includes a pump 5 for sucking bath water, a sterilizer 6 and a filter cylinder 7 filled with a filter medium.
And a heater-8.

The suction unit 2 is provided with a hair catcher made of foam or net for removing coarse dust such as hair as well as sucking bath water. It will pass through the catcher. Then, it is planned to be removed by the filter medium in the filter cylinder 7, but in most cases, the biological filtration by bacteria is adopted for the purification in the filter cylinder 7, and the bacteria adhere to the filter medium. , Until the purification becomes stable
It takes two weeks. Therefore, until the bacteria adhere to the filter medium, the turbid component is not removed and the turbid component is circulated again from the supply unit into the bath, so that so-called initial turbidity of bath water occurs.

[0004]

However, although it is indicated that initial turbidity may occur when using a circulating hot water bath, it usually only suggests this. No drastic measures were taken. However, in order to prevent initial turbidity in some parts, a physical filter that can remove even fine turbidity components was provided in the filtration cylinder, and a means was used in combination with biological filtration. However, there was a problem that the location of the circulating hot water bath was troublesome.

Furthermore, this kind of physical filter must be replaced frequently because it is prematurely clogged and causes a decrease in the flow rate in the circulation flow path of the circulation warm bath. However, the inside of the filter tube is contaminated with gel as bacteria propagate, and when taking out the physical filter from the inside of the filter tube in this state, the user feels uncomfortable and the work itself of taking out from the filter tube itself. Was complicated.

It is an object of the present invention to provide a circulating warm bath using a physical filter for removing fine turbid components that cause initial turbidity of bath water.

[0007]

The features of the present invention are as follows. That is, a circulating hot bath comprising a suction unit provided in the bathtub, a supply unit, and a filter cylinder and a pump for purifying the bath water between them, and a physical filter for removing the initial turbid component in the suction unit. The present invention relates to a circulating hot water bath characterized by being incorporated.

The physical filter used here is
Examples of are not biologically or chemically reactive,
The turbid component is removed by physical adsorption or filtration. Examples of the woven or non-woven filter-face material are bent in a pleat shape, a hollow fiber membrane, and rolled. Examples thereof include filters, and it is particularly preferable to use a filter surface material that has been subjected to anion treatment, cation treatment or lipophilic treatment.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION In the present invention, a physical filter capable of removing even fine turbidity components is incorporated into a suction unit to prevent initial turbidity and prevent an increase in size of a circulating warm bath. Furthermore, compared to the case where this physical filter is inside the filtration cylinder, it is possible to avoid seeing dirt due to bacteria when removing the physical filter, and because it is in a positional relationship that allows work while bathing, biological filtration is stable. The filter can be easily removed by the user 1 to 2 weeks after the start of use.

The main substances that make the bath water cloudy are secretions from the body of the bather, soaps, cosmetics, bath agents, stains on raw water, and the physical filter for removing these is woven or non-woven fabric. Examples of the filter surface material are a pleated shape and a hollow fiber membrane. Particularly, the filter surface material is preferably anionized, cationized, or lipophilic. The prepared product can adsorb negatively charged colloidal particles, and the cationized product can adsorb positively charged colloidal particles. Also, the lipophilically treated product has a feature that it can filter oil components that are not positively or negatively charged.

The physical filter is usually housed in a case in which the inlet and outlet of bath water can be easily connected with a hose or the like in the suction unit. This physical filter can be removed together with the case from the suction unit, and the fine turbidity that causes the initial turbidity from the bath water that has passed through the hair catcher attached to the tip of the suction unit. The components are removed and supplied to the pump. Therefore, it is sufficient to remove this physical filter after 1 to 2 weeks from the start of use when the filtration by organisms starts stably,
It is possible to prevent a decrease in flow rate due to clogging of the filter.

[0012] Preferably, after removing the physical filter, a case filled with a deodorant can be connected to prevent an offensive odor of the bath water, and a case filled with antibacterial ceramics can be used. By connecting, it is possible to prevent slimming of the bathtub.
