Description

[Detailed description of the invention] [Industrial applications]

The present invention relates to a hot-water circulation type bathtub apparatus that keeps hot water at a constant value by a heating means, keeping hot water filtered by a hot-water refining material such as a filter, and particularly, hot water which can be conveniently installed in a narrow bathtub space. The present invention relates to a hot water circulating bath apparatus having a fining material.

[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 keeping the hot water clear. The heating means keeps the temperature of the hot water at a constant temperature, and the hot water fining material such as a filter continuously removes foreign substances such as dirt and keeps the fine water. 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 fining material, one that filters hot water and sterilizes bacteria contained in the hot water, or one that agglutinates foreign substances contained in the hot water to facilitate separation thereof is used.
For example, "barley stone" is used as a warm water refining material of natural stone. 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 hot water is circulated, the ceramic filter creates a comfortable environment for the propagation of microorganisms, and the microorganisms parasitize the environment. 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 solve this drawback, the present inventors have developed a device in which a 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 Laid-Open No. 63-114642.
No. in the official gazette. In the apparatus described in this publication, as shown in FIGS. 5 and 6, a suction port 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 in a U-shape so as to be mounted on the bathtub K. In this apparatus, a filter cassette 16 is connected to a lower end of a relay pipe 15. Filter cassette 16 has suction port 17 on the outer circumference
Is open. Further, a cylindrical filter 18 is built in the filter cassette 16 and the cylindrical filter 18 is provided.
The inside of 18 is filled with a mixture of mineral grains and porous ceramic.

[Problems to be solved by the invention]

The bath water activating device shown in FIG. 5 is used by being attached to a bathtub as shown in FIG. Filter cassette 16
The hot water in the bathtub K is sucked in from above, 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, it is difficult to design the whole as compact and to dispose a large amount of hot water fining material in the bathtub. If a large amount of hot water fining material is used to cleanly filter hot water in the bathtub, the filter cassette becomes large and the bathtub becomes narrow. As in the device described in this publication, the filter cassette used to activate bath water is:
There is no need to make it so large. However, the hot-water circulating bathtub device, which continuously filters the bathtub water and keeps it clear, so that you can take a bath anytime for 24 hours without changing the hot water in the bathtub, reduces the amount of hot water refining material used. Is extremely difficult. This is because a small amount of hot water refining material cannot keep hot water clear. For this reason, when a large amount of hot water fining material is filled in the filter cassette, it is difficult to dispose the filter cassette in the bathtub so as not to interfere. Many bathtubs used at home are small, and it is extremely important how widely the bathtub can be used. Further, since the apparatus shown in FIG. 7 is used by mounting the U-shaped main body case 14 on the wall surface of the bathtub K, there is a disadvantage that the main body case 14 becomes an obstacle when taking a bath. Furthermore, the bath water activating device shown in FIG. 7 has a disadvantage that it takes time to clean the clogged filter cassette 16. In order to prevent clogging, a cylindrical filter 18 is provided inside the filter cassette 16, but with this structure, the cylindrical filter 18 cannot be taken out and easily cleaned. For this reason, the bath water activation device of this structure
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 hot water clear. This invention was developed with the aim of further resolving this drawback, and the important purpose of this invention is to provide a hot water fining material that does not occupy the space in the bathroom and can make the whole device extremely compact. An object of the present invention is to provide a hot water circulating bathtub apparatus provided with the same.

[Means for solving the problem]

The hot water circulation type bathtub apparatus of the present invention includes an injection / inhalation unit 1 and a circulation pump 2 connected to the injection / inhalation unit 1 for forcibly circulating hot water in the bathtub K to the injection / inhalation unit 1. A hot water fining material 4 that is disposed in the middle of a hot water passage forcibly circulated by the circulation pump 2 and that filters hot water and keeps it clarified, and a heating means 8 that heats hot water to a predetermined temperature. Prepare. The injection / inhalation unit 1
An injection suction casing 7 having a suction port 5 for sucking hot water in the bathtub K and an injection port 6 for spraying hot water into the bathtub K is provided. Further, in the hot water circulation type bathtub apparatus of the present invention, the injection / suction unit 1 is connected to the circulation pump 2 by the circulation hose 3 and is detachably attached to the bathtub K via the suction cup 13. Injection and suction casing 7 of injection and suction unit 1
Has an injection port 6 at the upper end and a suction port 5 at the lower end, and
A hot water fining material chamber 1A is formed between the upper end outlet 6 and the lower end inlet 5 and is closed in a watertight structure, being formed in a shape extending from the upper end outlet 6 to the lower end inlet 5. The warm water refining material room 1A is filled with granular hot water refining material 4,
The injection suction casing 7 is used in combination with the casing of the hot water refining material 4, and the hot water refining material 4 is stored in a useless space formed between the injection port 6 at the upper end and the suction port 5 at the lower end. Further, in the hot water circulation type bathtub apparatus of the present invention, a primary filter 10 is detachably mounted on the suction side of the injection / suction unit 1. The hot water that has passed through the primary filter 10 is circulated into the bathtub K through the hot water fining material 4 filled in the hot water fining material chamber 1A of the injection suction casing, the circulation hose 3, and the circulation pump 2. , And is kept clear with warm water refining material.

[Action]

In the hot water circulation type bathtub apparatus of the present invention, hot water is forcibly circulated by the circulation pump 2. The circulation pump 2 sucks warm water from the bathtub K through the primary filter 10, passes through the hot water refining material 4, and returns to the bathtub K again. The hot water fining material 4 filters hot water passing therethrough to maintain clarity.
The heating means 8 is controlled by a temperature sensor 9 for detecting the temperature of the hot water, and keeps the temperature of the hot water in a certain range. Therefore,
The hot water in the bath is kept clear and at a constant temperature. The hot water fining material 4 is stored in the injection / suction casing 7 of the injection / suction unit 1 set in the bathtub K.
The injection / inhalation unit 1 is detachably attached to the bathtub K via the suction cup 13 and connected to the main body case via the hose 3. The injection / suction unit 1 having this structure includes a suction cup 13
Can be removed from the bathtub K and shaken by hand to give a vibration, or the bathtub K can be hit to give a vibration or an impact. Vibration or impact separates deposits adhering to the granular hot water fining material 4 filled therein. Granular warm water refining material 4
However, when subjected to vibration or impact, adjacent objects collide with each other or move relative to each other to separate deposits adhering 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. In addition, the hot water circulation type bathtub device of this invention effectively uses the wasteful space that can be used for the injection / suction unit,
Compared with the conventional hot-water circulating bathtub apparatus, the exclusive space outside the bathtub can be significantly reduced without increasing the space inside the bathtub. That is, the injection / suction unit 1 requires the injection / suction casing 7 in order to fix the suction port 5 and the injection port 6 at fixed positions in the bathtub. Further, the suction port 5 and the injection port 6 need a considerably thick nozzle in order to circulate a large amount of hot water, and the circulation hose 3 connected to this nozzle also needs to use a thick one. Incidentally, in the hot water circulation type bathtub apparatus manufactured and sold by the present invention, the inside diameter of the injection port 6 and the circulation hose 3 is about 1.5 cm, and the inside diameter of the suction port 5 is 5 × 2.5 cm. The injection and suction casing 7 that accommodates the two thick circulation hoses 3 is relatively large, and a space is formed between the circulation hose 3 and the injection and suction casing 7. The injection suction casing 7 actually manufactured and sold by the present inventor has an inner width of 7.5 cm and a depth of 3.5 to 4 cm, and is provided with two circulation hoses 3 having an inner diameter of 1.5 cm. It is stored. About 2 kg of the hot water refining material 4 can be built in the space of the injection suction casing 7. The 2 kg ceramic filter has enough capacity to continuously filter 200 liters of hot water. Therefore, the hot water circulating bathtub device equipped with the hot water refining material of the present invention can be easily installed in a small bathroom without disturbing,
In addition, the filtering ability can be increased, and the feature that the hot water can be filtered clearly for a long time is realized. Further, in the hot water circulation type bathtub apparatus of the present invention, a primary filter 10 is provided at the suction port of the injection suction casing 7 and circulated through the hot water refining material 4 filtered by the primary filter 10.
The primary filter removes foreign substances such as hair and scale contained in warm water. Since the warm water from which these foreign substances have been removed is circulated through the warm water refining material, clogging of the warm water refining material is effectively prevented. Since the primary filter is detachably provided at the suction port of the injection suction casing filled with the hot water fining material, the primary filter can be removed for easy cleaning.

[Effect of the invention]

The hot water circulation type bathtub apparatus of this invention realizes the following extremely convenient features which cannot be realized by the conventional apparatus with a unique configuration. That is, the hot water circulation type bathtub apparatus of the present invention is disposed at the bottom and the top of the bathtub, and effectively utilizes a wasteful gap formed between the injection port and the suction port which are disposed apart from each other. Here, warm water fining material is filled. The inlet is designed to prevent uneven temperature in the hot water in the bathtub,
Hot water is sucked from the bottom of the bathtub in order to inhale foreign substances deposited on the bottom and clarify the inside of the bathtub. The injection port is provided at an upper part of the bathtub to make the temperature of hot water in the bathtub uniform. Therefore, the inlet and the outlet are arranged apart from each other. Since the inlet is located as far as possible at the bottom of the bathtub and the outlet is located above the hot water level of the bathtub, the inlet and outlet are far apart. Further, the injection / suction unit in which the injection port and the suction port are disposed above and below the injection / suction casing has a thick upper portion. This is because two circulation paths for circulating hot water are provided in both the injection port and the suction port. The hot water circulation type bath tub device of the present invention is that the upper part of the thickened injection suction casing is extended to the lower suction port to form a box shape, and a hot water fining material room of a wide space is provided between the suction port and the injection port. Features. The hot water refining material chamber provided here is formed by extending an upper portion having an increased inner shape to a lower suction port in order to provide two circulation paths. In addition, since the injection port and the suction port need to be separated, the accumulation of the hot water refining material chamber becomes considerably large. The volume of the hot water refining material chamber increases in proportion to the product of the horizontal cross-sectional area and the vertical length. The horizontal cross-sectional area of the hot water refining material chamber becomes large because two circulation paths are provided at the upper part of the injection suction casing. The length of the hot water fining material chamber in the vertical direction increases because the injection port and the suction port are separated. For this reason, the hot water fining material chamber becomes considerably large and can be filled with a large amount of hot water fining material. Further, the hot water circulation type bathtub apparatus of the present application does not fill the hot water refining material chamber with a large amount of hot water refining material, and does not make the bathtub narrow. This is because a large amount of hot water fining material is filled by effectively utilizing the wasteful space created between the inlet and the outlet. In the hot water circulation type bathtub apparatus of the present invention, the space between the suction port and the injection port cannot be made thin because the injection suction casing between the suction port and the injection port is filled with the hot water fining material. However, even if the space between the inlet and the outlet is narrowed, the bathtub cannot be widely used. Further, even if this portion is made almost the same thickness as the portion provided with the suction port and the ejection port, the bathtub does not become narrow. This is because there are thick parts at the top and bottom of the warm water refining room. Therefore, the hot water circulating bathtub apparatus of the present invention, in addition to being able to make the main body case installed in the bathroom small, furthermore, installing an injection / inhalation unit so as not to obstruct the narrow bathtub, the suction port and the injection port It is possible to fill a large amount of hot water fining material into the injection suction casing provided with the above. With this unique configuration, the hot water circulating bathtub device of the present invention can keep hot water clarified with a large amount of hot water fining material, and has succeeded in making the whole device extremely compact and utilizing the space extremely effectively. It is. Further, the hot water circulation type bathtub apparatus of the present invention does not need to provide a special casing for filling the hot water refining material although the hot water refining material is filled in a large amount. This is because an injection / suction casing for providing an injection port and a suction port in the injection / suction unit is used in combination with a casing made of a hot water refining material. For this reason, the feature that the number of parts can be reduced and the device can be manufactured at low cost can be realized. Furthermore, the hot water circulation type bathtub device of this invention has an injection port and a suction port opened, and connects the injection / suction unit filled with hot water fining material to the circulation pump through the circulation hose. In addition, since it is structured to be attached to the bathtub via a suction cup, the injection / inhalation unit can be easily and easily placed in a position where it does not interfere with the bathtub, and the main body case can be placed in a position where it does not interfere with the narrow bathroom. There is also a feature that can be installed in an ideal state without taking it. Furthermore, a remarkable feature of the hot water circulation type bathtub apparatus of the present invention is that the hot water fining material can be easily and easily and cleanly cleaned without providing a mechanism for cleaning the hot water fining material. That is, the hot water circulation type bathtub apparatus of the present application fills a hot water fining material chamber into a hot water fining material chamber provided in an injection / suction casing, and connects the injection / suction unit provided with the injection / suction casing to a main body case with a hose. At the same time, the injection / suction unit is detachably attached to the bathtub via the suction cup. The hot water circulating bathtub device of this structure can remove the injection / suction unit from the bathtub and shake it by hand to apply vibration, or hit the bathtub with the injection / suction unit to apply an impact to the injection / suction casing. is there. Vibration or impact of the injection suction casing separates deposits adhered to the granular hot water fining material filled therein. 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. In the granular hot water fining material washed in this state, sediment separated by vibration or impact is quickly discharged from the hot water fining material chamber, and is cleaned very efficiently and cleanly. Furthermore, the hot water circulation type bathtub apparatus of the present invention has a built-in hot water fining material for the injection / suction casing of the injection / inhalation unit, and communicates with the hot water fining material chamber of the injection / suction unit to detachably attach the primary filter. I am wearing it. The hot water fining material chamber with this structure not only can effectively prevent the clogging of the hot water fining material, but also can easily and easily and quickly clean the primary filter that prevents the clogging of the hot water fining material. is there. The reason is that the hot water circulation type bathtub apparatus of the present invention incorporates the hot water fining material in the injection suction casing and the primary filter is detachably attached to the suction port of the injection suction casing. Removably attached to the suction port of the injection suction casing containing hot water fining material 1
The next filter keeps the hot water circulation pump running,
In addition, there is a feature that washing can be easily performed in a state where hot water is circulated through the hot water refining material. 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.
