Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water circulation device that enables water circulation in bathtubs, fish farming facilities, and the like.

[Prior art and its problems] When bathing water is used repeatedly, it is necessary to remove at least human hair, dust, etc. mixed in the bathing water. On the other hand, in order to improve the bath effect,
Active ingredients such as minerals contained in activated stones are dissolved in bath water. Therefore, in a water circulation device that has these features,
The structure is such that the filter and activation tank are connected to the bathtub via a circulation path.

However, in such devices, the water spoils prematurely, giving off a bad odor and creating a sticky feeling, which poses a problem. For this reason, new sterilization means such as chlorine-based sterilizers and ozone-based sterilizers for sterilizing water are being added to the circulation path. Although this makes it possible to recycle to some extent, long-term use still causes water to become foul-smelling and sticky, and is not a fundamental solution.

The present invention was made in consideration of the above circumstances, and an object of the present invention is to provide a circulation device that can circulate and use water for a long period of time.

[Means for Solving the Problems] In order to achieve the above object, the inventor of the present invention conducted extensive research and discovered that the foul odor and stickiness of water are caused by the growth of aerobic bacteria. In other words, the temperature of bath water is 40, which is the appropriate temperature for bacteria to grow.
This is because the temperature is maintained around ℃, and there are spaces (air pockets) that encourage the growth of bacteria inside the filter and activation tank, and aerobic bacteria grow within these air pockets. Moreover, the growth of bacteria produces mold, and this mold has strong resistance to chlorine, ozone, etc., making it difficult to remove. Based on the above findings, the inventor conducted further research and found that by filling the filter and activation tank with water to eliminate the breeding space for aerobic bacteria, the water becomes foul-smelling and sticky. We discovered that this can be prevented for a long time and completed this invention. That is, the water circulation device according to the present invention is a water circulation device in which a filter for filtering water and an activation tank filled with activated stones containing active ingredients are connected in series to a circulation path. The filtration device includes a filtration body consisting of a discharge pipe whose upper and lower ends are open and covered with a filtration cloth, and water that has passed through the filtration cloth is introduced from the upper end of the discharge pipe and from the lower end of the filtration body. and a container that supports the filtration body in an upright state so as to be discharged into the circulation path, and the upper end of the discharge pipe is provided close to the lower surface of the lid of the container, and the activation tank comprises a tank body filled with the activated stones, an outlet pipe whose upper end is open and whose lower end is connected to the circulation path and is inserted vertically into the tank body, and water is introduced into the tank body from the lower part. In addition, the upper end portion of the outlet pipe is provided in close proximity to the lower surface of the top plate of the tank body.

[Function] Since the present invention is constructed as described above, both the filter and the activation tank are always filled with water and no air pockets are formed.

[Example] Hereinafter, the present invention will be specifically described with reference to an illustrative example.

This embodiment is applied to a circulation device that circulates bath water in a bathtub, and as shown in FIG. A nozzle box 30 is provided, and these are connected by a circulation path 40. The main box 1 includes a filter 3, an activation tank 4, and a pump 8 in a frame 2, and an ozone generator 6 and a control board 7 in a compartment separated from these by a heat insulating plate 5. It is provided. On the other hand, the circulation path 40 includes an outgoing pipe 41 that guides the bath water sucked from the nozzle box 30 into the filter 3, and a return pipe 42 that returns the bath water from the activation tank 4 to the nozzle box 30. The filter 3, pump 8, and activation tank 4 are connected in series through this circulation path 40. In this case, circulation of the bath water is performed by driving the pump 8.

The filtration device 3 filters the water introduced into the interior to remove human hair, dust, etc., and the filtration device 3 filters the water introduced into the interior to remove human hair, dust, etc. The body 11 is constructed in an upright manner. As shown in the second figure, the filter body 11 has upper and lower end portions 12a, 1
A discharge pipe 12 with an open end 2b, and a core cylinder 13 whose lower end is screwed into the container 10 and stands upright inside the container 10.
and a filter cloth 14 wrapped around the outer surface of the core tube 13. In this case, the lower part of the discharge pipe 12 is connected to the container 1.
The discharge pipe 12 is erected in the vertical direction of the container 10 . Further, the lower end 12b of the discharge pipe 12 is extracted from the lower surface of the container 10 to the outside, and is fitted into a pipe line 43 that connects the pump 8 and the filtration device 3. Furthermore, there is a predetermined gap between the discharge pipe 12 and the core tube 13, and the water filtered by the filter cloth 14 passes through the core tube 13 and fills this gap. After that, it is discharged to the outside from the upper end 12a of the discharge pipe 12. For this reason, core tube 1
3 is formed of a porous cylinder or a water-permeable cylinder to allow water to pass through. The filter cloth 14 is wound so as to cover the entire outer surface of the core tube 13, and is made of, for example, a foamed urethane sheet, a glass wool fiber bundle, or the like.
Further, a presser lid 15 is screwed onto the upper end of the core cylinder 13 to cover the upper part of the discharge pipe 12.
This prevents the water that has flowed into the pipe from being discharged from the upper end 12a of the discharge pipe 12 without being filtered.
In such a filtration device 2, the upper end 12a of the discharge pipe 12 is set to a dimension that is slightly lower than the upper end of the core tube 13, and is provided close to the lower surface of the lid 9 of the container 10, Upper and lower ends 12a, 1
2b is open, which allows the upper end 1
2a serves as an inlet for filtered water, and the lower end portion 12b serves as an outlet for filtered water. Therefore, the water level of the bath water sucked into the container 10 from the outgoing pipe 41 rises from the bottom of the container 10, and as the water level rises, the air filling the container 10 flows to the upper end of the discharge pipe 12. It is discharged to the outside through 12a. In addition, as the water level rises, the bath water is filtered through the filter cloth 14 and gradually fills the gap between the discharge pipe 12 and the core tube 13, and the air in this gap is also discharged in the same way. .
Then, when the container 10 is full, the container 10
All the air inside the filter is expelled, and no air pockets are generated inside the filter 2. Therefore, there is no room for aerobic bacteria to grow. Also, container 10
The inside is filled with water, and the entire filter cloth 14 is used for filtering, so that the filter area is wide and the filtering rate is improved, and there is also the advantage that it is difficult to get clogged. In FIG. 1, 16 is a drain tank, which is opened manually or automatically when replacing or cleaning the filter body 11.

As shown in FIG. 1, the activation tank 4 has a structure in which a tank body 17 having a predetermined volume is filled with activated stones 18 and polyhard activated ceramics. In this case, a separator 1 made of punching metal, a net, or a foamed urethane sheet is provided at the bottom of the tank body 17.
9 is installed, and the activated stone 18 is attached to this separator plate 1.
Filled on top of 9. As an active stone, Maifan stone,
One or more types of sulfur stone, obsidian, flowstone, unweathered nacre can be selected, and when bath water passes through the activation tank 4, ions are exchanged with the activated stones, and magnesium and zinc are also added. Minerals such as minerals and active ingredients such as calcium and sodium are dissolved, and the hydrogen ion concentration is adjusted to around neutrality. As a result, active ingredients beneficial to the human body are dissolved in the bathing water, thereby imparting bathing effects. The activation tank 4 has an inlet 20 formed on the bottom surface thereof for introducing bath water into the tank body 17, and a conduit 44 from the pump 8 is connected to the inlet 20. Further, an outlet pipe 21 is inserted into the tank body 17 in the vertical direction. Only the upper and lower ends of this outlet pipe 21 are open, the lower end passes through the tank body 17 and is connected to the return pipe 42 of the circulation path 40, and the upper end 21
a extends close to the lower surface of the top plate of the tank body 17. In such a structure, bath water is introduced into the tank body 17 from the inlet 22, and the water level gradually rises. As the water level rises, the air in the tank body 17 is discharged to the outside through the upper end 21a of the outlet pipe 21. When the tank body 17 is filled with water, no air pocket remains in the tank body 17.
Similar to the filter 3, there is no room for aerobic bacteria to grow. Therefore, air pockets in which aerobic bacteria breed are not generated in the water circulation paths including the filter 3 and the activation tank 4, so long-term circulation is possible without the occurrence of bad odors or stickiness caused by bacterial growth. is now possible. Here, a heater 22 is installed at the bottom of the tank body 17 partitioned by the separator 19.
is provided. The heater 22 can be a far-infrared heater or the like, and is used to raise the bathing water introduced into the activation tank 17 to a temperature suitable for bathing. As a result, bath water is always kept at around a predetermined temperature and can be used for bathing. Further, a safety switch 23 is provided at a position close to this heater 22. The safety switch 23 is a float switch in which a float 23a moves up and down depending on the water level of the bath water. In this case, float 23
The heater 22 is in the ON state when float a is floating slightly above the heater 22, and when the water level drops and the float 23a moves below the heater 22, the heater 22 is turned OFF. It operates. This prevents the heater 22 from overheating and improves safety.

The ozone generator 6 and the control board 7 are separated from the circulation system by a heat insulating plate 5. This is because the amount of ozone generated by the ozone generator 6 is good when the temperature is low, and the control board 7 works well when the temperature is low and the humidity is low. The ozone generator 6 supplies the generated ozone into the bath water, and therefore the air supply pipe 24 is connected to the nozzle box 30.
extends inward. The air supply pipe 24 is provided with a valve 25 such as a solenoid valve or a check valve to prevent bath water and steam from entering the ozone generator 6. In this case, the air supply pipe 24 and the valve 25 are made of a material such as silicon or stainless steel that is not corroded by ozone. The control board 7 is equipped with various control mechanisms such as a bath water heating temperature control section, an ozone generator operation control section, and a bath water circulation control section, thereby enabling automatic control.

Next, as shown in FIG. 3, the nozzle box 30 is connected to an outgoing pipe 41 and an incoming pipe 42 through valves 31, respectively. This nozzle box 30 is set inside the bathtub 52, and the nozzle 3 is mounted on the front plate of the hollow head 32.
3 is attached, and a return pipe 42 is connected to this nozzle 33. In addition, a water guide hole 34 is provided at the lower back side of the head 32 to guide bath water inside, and the outgoing pipe 41 is connected to the head 3 from this water guide hole 34.
This is to suck the water that has flowed into the tank. Furthermore, the air supply pipe 24 from the ozone generator 6 is connected to the nozzle 3.
Connected to 3. In such a structure, the bathtub 5
The bath water in 2 is guided from the outgoing pipe 41 to the filter 2 and purified, then led to the activation tank 4 where the active ingredients are melted, and heated by the heater 22, and then passed through the outgoing pipe. 42 and returned to the bathtub 52,
Water is recycled. Furthermore, since ozone is mixed into the bath water during circulation, sterilization and oxidative decomposition of fats and oils are carried out, making it possible to use the bath water in a long-term circulation. Note that the nozzle box 30 may be omitted, and in this case, the structure can be improved by attaching the nozzle 33 directly to the bathtub using a suction cup or the like, and by directly immersing the outgoing pipe 41 in the bath water. Simplified.

Although the above example shows the case where it is applied to a bathtub, the present invention can also be used for water circulation in fish farming facilities, and in this case, the active ingredients from the activated stones are absorbed into the bodies of the fish. , has the effect of growing fish with good taste at an early stage. Further, the activated stone filled in the activation tank may be a powdered activated stone. In this case, since the surface area of the activated stone increases, the active ingredient can be dissolved in a high concentration. In the case of such powder, leakage of the activated stone powder can be prevented by providing a filter cloth at the upper end of the outlet pipe 21 or the like.

[Effects of the invention] As explained above, in the present invention, the filtration device that filters water and the activation tank that melts the active ingredients are both located close to the bottom surface of the top plate of the container body. The structure drains water from the top so that no air pockets remain inside, which prevents the growth of aerobic bacteria and allows for long-term circulation of water without the foul odor and stickiness caused by bacterial growth. becomes.
