Description

[Detailed description of the invention]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water circulating bath apparatus which keeps hot water clarified by filtering hot water through a hot water refining material such as a filter, and maintains the temperature of the hot water at a constant value by a heating means. The present invention relates to a hot water circulating bathtub device that can be conveniently installed in a space.

[Prior art]

2. Description of the Related Art A hot water circulating bathtub apparatus has been developed which keeps hot water in a bathtub at a constant temperature and keeps hot water clear.
This hot water circulation type bathtub apparatus includes a heating means for keeping the temperature of the hot water constant, and a hot water refining material such as a filter for refining the hot water. The heating means keeps the temperature of the hot water at a constant temperature, and the hot water refining material continuously removes foreign substances such as dirt to keep the hot water clear. Therefore, the hot-water circulating bathtub apparatus having this structure can take a bath at any time for 24 hours without changing the hot water in the bathtub.
This device can be used very conveniently, and since it does not drain after bathing, water can be effectively used and the water saving effect can be enhanced. As the hot water fining material for hot water filtration, for example, inorganic natural stones and ceramics obtained by sintering inorganic materials are used. As the hot water refining material, one that filters hot water, one that sterilizes bacteria contained in the hot water, or one that aggregates dirt and the like contained in the hot water to facilitate separation is used. As a warm water refining material of natural stone, for example, “Marihanishi” is used. Further, a stone obtained by pulverizing this stone and sintering it in a porous state can also be used. A ceramic filter obtained by crushing barley stone and sintering it in a porous manner adsorbs ammonia (sweat), protein (stain), and the like from the human body. It has been clarified that the ceramic filter adsorbs ammonia and proteins contained in warm water depending on the following conditions. That is, when warm water is circulated, the ceramic filter creates a comfortable environment for the propagation of microorganisms, and the microorganisms parasitize here. Microorganisms eat ammonia and proteins contained in warm water as food and decompose. Therefore, sweat and dirt in the warm water are effectively adsorbed on the ceramic filter by the microorganisms. A ceramic filter that clarifies hot water in this state is different from a hot water fining material that simply filters out foreign substances,
In a short time, clogging does not occur, and the washing period of warm water can be extended. For example, 200 liters of warm water is added to an average particle size of 5-2
When 2 kg of a ceramic filter having a diameter of 0 mm is used for continuous filtration, the number of people who take a bath for 5 to 10 people per day can be used for as long as several months. The present inventor first developed and commercialized a hot water circulation type bathtub apparatus for outdoor installation. The device was connected to the tub by two hoses that penetrated the tub wall. This hot water circulating bathtub apparatus has a drawback that the installation work is troublesome. The reason is that the bathtub is installed with a through hole in the wall. Also,
There was also a disadvantage that it could not be installed unless there was space outside the building close to the bathtub. As a hot water circulating bathtub device that solves this drawback, a device for installation in the bathroom has been developed. The device can be easily installed because it can be installed without piercing the bathroom wall. However, this device has the disadvantage of occupying a narrow bathroom space. In order to further solve this drawback, the present inventor has developed a device in which the filter is formed into a thin plate and laid on a bathroom floor (Japanese Utility Model Application No. 63-327286). Although the hot water circulation type bathtub apparatus of this structure is not restricted by the installation place of the filter, since it is installed on the floor, there is a drawback that a step is formed on the floor.
By adjusting the outer shape of the filter to the shape of the floor, the steps can be eliminated. However, to achieve this, the filter must be specially manufactured for the bathroom floor. This is practically impossible in terms of cost. Further, since the filter used by laying on the floor is used on the upper surface, it is necessary to be strong. That is, there is also a disadvantage that the structure becomes expensive due to the strong structure. Furthermore, the device for circulating hot water through the hot water fining material provided outside the bathtub has a drawback in that heat is radiated from the hot water fining material and thermal efficiency deteriorates. In order to reduce unnecessary heat radiation, the casing that contains the hot water fining material is insulated. However, it is not possible to eliminate heat radiation even with heat treatment. As a device for preventing such adverse effects, a device for activating a bath water in which a filter is provided in a bathtub has been disclosed in Japanese Utility Model Application Laid-open No.
No. in the official gazette. In the apparatus described in this publication, as shown in FIGS. 7 and 8, a suction port 17 for sucking warm water in a bathtub is filled with a mixture of mineral particles and a porous ceramic. In the bath water activating device having this structure, the main body case 14 is formed into a U-shape so as to be mounted on a bathtub. In this apparatus, a filter cassette 16 is connected to a lower end of a relay pipe 15. The filter cassette 16 has an inlet 17 on the outer periphery. Further, a cylindrical filter 18 is built in the filter cassette 16, and the cylindrical filter 18 is provided.
The inside is filled with a mixture of mineral grains and porous ceramic.

[Problems to be solved by the invention]

The bath water activation device shown in FIG. 7 is used by being attached to a bathtub as shown in FIG. Filter cassette 16
The hot water in the bathtub is sucked into the bathtub, and the hot water is injected into the bathtub from an injection port provided at the lower end of the main body case 14. The device having this structure has a feature that waste heat radiation from the hot water fining material can be reduced because the hot water fining material is disposed in the bathtub. However, the apparatus having this structure has a disadvantage that it is difficult to dispose a large amount of a hot water fining material such as a porous ceramic in a bathtub with a strong structure. The warm water refining material is considerably heavier because it uses inorganic natural stones and ceramics obtained by sintering the inorganic material. Furthermore, a hot-water circulation bathtub apparatus that filters hot water continuously for 24 hours to clarify it requires a large amount of heavy hot-water fining material to keep hot water in the bathtub clean. Rather than filtering the bath water clear, the filter cassette used to activate the hot water does not need to use as much mineral particles or porous ceramics. However, the tub water was continuously filtered and kept clarified, without replacing the hot water in the tub 24
A hot-water circulating bathtub apparatus that allows bathing at any time of the day requires a considerable amount of hot-water fining material. This is because a small amount of hot water refining material cannot keep hot water clear. If a large amount of hot water refining material is disposed in the bathtub with the structure shown in FIG. 9, the filter cassette 16 becomes heavy, and it is difficult to dispose it at a fixed position in the bathtub with a strong structure. This is because the heavy filter cassette 16 is disposed in a suspended state at the lower end of the elongated relay pipe 15. Further, the apparatus shown in FIG.
There is also a disadvantage that when the mineral particles and the porous ceramic are clogged, they cannot be easily washed. In this apparatus, in order to prevent clogging of the hot water fining material, a cylindrical filter 18 is disposed inside the filter cassette 16, and the warm water passing through the cylindrical filter 18 is passed through the mineral particles and the porous ceramic. ing. This structure has a cylindrical filter 18
Can reduce clogging of porous ceramics, etc.
The cylindrical filter 18 is clogged. Tubular filter 18
Is arranged on the inner surface of the filter cassette 16,
Not easy to clean. For this reason, it can be used for a device that has a short operating time, but cannot be used for a device that operates continuously for 24 hours to keep warm water clear. The present invention has been developed with a view to overcoming this drawback.

The injection / inhalation unit 1 of this structure can remove the suction cup 13 from the bathtub K and shake it by hand to apply vibration to the hot water fining material case, or hit the bathtub K to apply vibration or impact. Vibration and impact separate the sediment adhering to the granular hot water fining material 4B filled therein. This is because, when the granular hot water fining material 4B is subjected to vibration or impact, the adjacent ones collide with each other or move relative to each other to separate the deposit attached to the surface. Furthermore, while the circulation pump 2 is operated, the deposits can be quickly removed and washed in a state in which the injection / suction unit 1 is subjected to vibration or impact to circulate hot water.

[Effect of the invention]

The hot water circulating bath apparatus according to the present invention can realize an extremely excellent feature that the hot water fining material can be easily, easily and neatly cleaned without providing a mechanism for cleaning the hot water fining material. The hot water circulating bathtub device of this invention is equipped with hot water fining material in the injection / suction unit, connects the injection / suction unit to the main body case with a circulation hose, and connects the injection / suction unit through the suction cup. This is because it is detachably attached to the bathtub. The hot water circulation type bath tub device of this structure removes the injection / suction unit from the bath tub and shakes it by hand to vibrate the hot water fining material, or hits the bath tub with the hot water fining material to give an impact to the hot water fining material It is possible. Vibration and shock
Separate the sediment attached to the granular hot water fining material. In particular, the hot water circulation type bathtub apparatus of the present application is configured such that the hot water refining material filled in the injection suction casing is granular. The granular hot water fining material receives vibrations or shocks, and adjacent ones collide with each other or move relative to each other, thereby efficiently separating sediments attached to the surface. Furthermore, in the hot water circulation type bathtub apparatus of the present invention, it is possible to apply vibration or impact by removing the injection / suction unit from the bathtub in a state where the circulation pump is operated. For this reason, remove the injection / inhalation unit from the bathtub and vibrate in the hot water in the bathtub, or beat the bathtub and circulate hot water etc. in the hot water refining material, and apply vibration or impact to the granular hot water refining material. It is possible to wash. The granular hot water fining material that is washed in this state, sediments separated by vibration or impact are quickly discharged from the hot water fining material, and are cleaned extremely efficiently and cleanly. Further, in the hot water circulation type bathtub apparatus of the present invention, a hot water fining material case filled with a hot water fining material is attached to the injection / suction unit in a shape extending in the vertical direction of the injection / suction unit.

Therefore, the hot water circulation type bathtub apparatus of the present invention has a feature that a large amount of hot water refining material can keep hot water more clear. In particular, the hot water circulating bathtub device of this invention fills a large amount of hot water fining material inside the hot water fining material case in a shape that extends vertically, so there is no need to make the hot water fining material case thick, and thin hot water fining material The material case can be filled with a large amount of warm water refining material. The injection / inhalation unit injects hot water as close to the surface of the bathtub as possible, and sucks in hot water from the bottom of the bathtub as much as possible. The reason why the hot water is sprayed near the water surface is to stir the hot water to be sprayed near the water surface so as to forcibly sink dirt and hair floating on the water surface below the water surface. The inhalation from the bottom of the bathtub is for the purpose of efficiently inhaling and removing foreign substances settling on the bottom. In order to arrange the suction port at the bottom of the bathtub and the injection port near the water surface, the injection / suction unit has a considerably long shape which is vertically extended. In the hot water circulation type bathtub apparatus of the present invention, the hot water fining material case is formed in a shape extending in the vertical direction of the long injection / suction unit, so that the hot water fining material case can be considerably lengthened.
Therefore, the hot water refining material case can be filled with a large amount of the hot water refining material material without disturbing the inside of the bathtub. In addition, the hot water circulation bathtub apparatus of the present invention can effectively prevent clogging of the hot water fining material, and can easily, easily, and quickly clean the primary filter that prevents clogging of the hot water fining material. There are also features that can be done. This is because the hot water circulation type bathtub apparatus of the present invention detachably attaches the primary filter to the suction side of the injection / suction unit. The primary filter, which is detachably attached to the suction side of the injection / inhalation unit, keeps the hot water circulation pump in operation, and circulates hot water through the hot water refining material.
There is a feature that can be easily washed. For this reason, the hot water circulation type bathtub apparatus of the present invention has a feature that, when bathing every day, the primary filter can be easily washed and clogging of the hot water fining material can be prevented. Furthermore, the hot water circulating bathtub apparatus of this invention uses a hot water fining material case of hot water fining material and an injection suction casing provided with a suction port and an injection port in separate cases, so that the hot water fining material can be easily renewed. There is also a feature that can be replaced with something.
