Description

        The present invention purifies the bath water by forcibly permeating 90% or more of the bath water through the filtration filter in the relationship between the hot water filtration tank and the filtration filter of the household circulating warm bath, and also makes it easy to replace or remove the filter filter. The present invention relates to a home-use circulating bath based on a new idea of preventing the growth of bacterial groups at the filtration function site by enabling cleaning.

        As a prior art related to the present invention, there is JP-A-10-216707 which is an idea of exchanging only a filter among a filter and a filter medium of a filtration function part.

In JP-A-10-216707, in which only the filter is taken out and cleaned, the filter medium is not cleaned, so that the pollutant is not stored, so that the pollutant is not stored as in the conventional case. There are significant differences from the present invention. Japanese Patent Application No. 2009-136987, which was previously filed by the applicant of the present application, is an invention relating to the improvement of a filter that exhibits the same effect.

      Household hot water baths that circulate and purify bath water in a home bath set to an appropriate bathing temperature for a long period of time, commonly called 24-hour baths, contain Legionella, Escherichia coli, and general bacteria in the bath water. These Legionella and Escherichia coli are representative of bacteria that live in harmony with humans, are universally present around the water in the living sphere, and are essentially harmless.

      While filtering the fat, sweat and fine exfoliated cortex dissolved in the bath water and purifying it with the action of organic matter-degrading bacteria that have settled in the porous granular ceramic and porous stone, UV lamps, ozone bubbles, chlorine, silver ions, A common purification method has been to use various means such as copper ion, electrolysis, and high temperature heating alone or in combination to reduce fungi in the bath water to below the safety standard value and return it to the bathtub. is there.

      The basis of this purification method is based on the idea of how to efficiently sterilize the grown fungi.

      However, when a filter material such as a filter or porous granular ceramic is taken out from the filtration tank in the circulator, the filth accumulated by the long-term circulation filtration is in the form of highly viscous sludge. Fat, sweat, and waste cortex are decomposed or denatured, and naturally become a hotbed of a group of bacteria that grow using these as food. There are very rare cases that have harmed the health of people.

      The present invention increases the purification efficiency by forcibly permeating 90% or more of the bath water in the filtration tank while constantly circulating an average hot water capacity of 250 to 300 liters in the home tub, so that the filtration filter can be used in a shorter time. It provides a filtration device that makes it easy to wash and clean the residue that remains, and to maintain and simplify the maintenance. Filter the residue that has been filtered in this circulation process either once or every two days. It is a household circulating bath that is taken out and cleaned and, in some cases, replaced with a filtration filter so that the filtration function unit does not become a hotbed in which fungal groups grow.

      The basis of the present invention is the idea that “proliferating fungi are cut off from their source” and has found a method for suppressing the growth of fungi in circulating bath water.

      In the present invention, a dome-shaped lid is screwed on the top so that the lid of the heat retaining jar can be attached and detached easily, and the bottom of the filtration tank has a reverse dome shape and the shape of the inner space is a capsule type. If you put a filtration filter that is a little longer than the inner space and flat at both ends, and tighten the dome-shaped lid and tighten it tightly, the outer edges of the upper and lower surfaces of the filtration filter are strongly pressed along the dome-shaped curved surface and the filtration tank Crimp firmly on top and bottom of. By doing so, almost all of the bath water flowing into the filtration tank is forcedly filtered. As a result, since the residue is collected in a short time in the filtration filter, it can be taken out and cleaned or replaced before the filter is clogged.

      Because of this structure, the operation of the main body is suspended at any time, the dome lid is screwed open, the filtration filter is taken out of the tank, a new or washed filtration filter is inserted, and the dome lid is again inserted. Tighten securely to complete the inspection and replacement, and resume operation as a 24-hour bath.

      The 24-hour bath circulates and purifies the bath water, thus saving water resources, reducing the amount of sewage treatment water, does not boil the bath from the beginning, does not waste power or gas, does not burn gas, and does not generate CO2 directly. This effect of preventing global warming will greatly contribute to Japan's eco-policies that began with the Kyoto Protocol. The present invention is extremely effective in suppressing direct CO2 emissions from households that continue to grow by making the 24-hour bath very popular with convenience, simplicity of handling and novelty that does not increase bacteria. To do.

      Hereinafter, the details of the present invention will be described with reference to the drawings.

      As shown in FIG. 1, a household circulating warm bath 1 of a bathroom installation type (hereinafter referred to as a main body) is fixedly installed at a corner of the upper edge of the bath.

      FIG. 2 shows a filtration filter (two-stage filtration filter in which a cylindrical primary filter 13 is placed on an outer peripheral surface of a bobbin-shaped secondary filter 14) in a filtration tank 8 of the present invention for a household circulating bath. FIG.

      Fine dust and molten impurities are filtered from the entire area of the filtration tank through the inlet 9 of the filtration tank 8 in the body filtration filter with activated carbon of the primary filter 13 and further purified through the secondary filter 14. Then, it returns to the bath from the spout 7 of the spout unit 6.

      FIG. 3 is an explanatory view showing the relationship between the primary filter 13 and the bobbin winding cartridge 14 in which an activated carbon-containing nonwoven fabric in which activated carbon is finely granulated is made into a cylindrical shape. The primary filter 13 utilizes the adsorptivity of activated carbon, and serves to purify impurities that are dissolved when bath water permeates and trap fungi.

      The inner diameter is slightly larger than the thickness of the bobbin cartridge so that it can be put on the outside of the secondary filter or removed.

      FIG. 4 shows a bobbin type having a length B of 250 mm, which is obtained by winding a thread-wound cartridge core 12 having a length C of 245 mm and a polypropylene thread having a thickness D of 14 mm and raising and lowering the core by 2.5 mm. The secondary filter 14. The filtration filter according to the present invention, which has a two-stage filtration function from the primary filter to the secondary filter by covering the outer peripheral surface with the primary filter 13 shown in FIG. When screwing and tightening the lid of the heat insulation jar in the same manner as screwing in and out, the filter filter B 250 mm longer than the length A246 mm from the dome-shaped ceiling inside the lid to the bottom of the reverse dome-shaped filtration tank The edge peripheral portions at both ends are compressed by 2 mm at the top and bottom and are strongly pressed against the dome-shaped curved surface.

      FIG. 5 shows a state in which a filtration filter longer than the depth between the dome-shaped lid inner ceiling and the bottom of the filtration tank is placed in the filtration tank 8 and the dome-shaped lid 11 is closed. The filtration filter is compressed between the ceiling inside the dome-shaped lid and the bottom of the filtration tank, and the top and bottom are crimped, so that over 90% of the bath water flowing into the filtration tank from the inlet 9 is filtered from the tank inner wall. If the filter gap is filled and the two steps from the entire area to the primary filter 13 and the secondary filter 14 do not pass through, the structure is such that it cannot exit from the outlet 10 through the mesh hole of the central cylindrical core. . Since the turbidity is removed through this filtration, the water quality becomes extremely high in transparency.

      In addition, the bobbin-shaped bobbin cartridge can use the commercial item currently used widely for water purification.

      Household circulation baths, so-called 24-hour baths, have daily conveniences that are free from the hassle of washing daily baths, filling a certain amount of water and boiling water at appropriate temperatures, and making additional cooking and adding hot water depending on the family bathing time difference. Resource saving effect that saves water and sewage by not replacing it, and no direct carbon dioxide generation due to gas combustion because it does not bathe, making it extremely useful among household appliances in contributing to and preventing global warming It is effective.

      In addition to these advantages, the present invention establishes low prices, simple handling, and sanitary safety, thereby increasing the number of purchasers and revitalizing the industry.
