Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is installed in buildings, condominiums, hospitals, schools, etc., and is used as a water storage tank for temporarily storing tap water, a hot water storage tank for a water heater, or for viewing or breeding. Regarding all kinds of water tanks such as fish tanks etc.

0002

[Prior Art] In recent years, the quality of water from rivers, dams, etc. that serve as raw water for tap water has deteriorated, and complete purification at water treatment plants is nearly impossible. However, the result was that it remained. In addition, Japan's geology generally has a lot of acidic soil, and the water quality tends to be acidic due to the effects of acid rain caused by air pollution, which activates the nutrients necessary for the reproduction of microorganisms and encourages their proliferation. Furthermore, the acidic water quality caused water pipes and water tanks to corrode and cause red rust, causing red water.

[0003] Generally, in buildings, condominiums 30, etc., a water tank 31 and an elevated water tank 32 are installed as shown in FIG. However, as shown in FIG.
In most cases, water is supplied from the upper part of the tank and water is discharged from the lower part at a diagonal position. Therefore, in this conventional structure, old water accumulates in the area shown by the mesh in the figure, forming a so-called dead water area. In particular, in the dead water area 37 near the water surface, the light that has passed through the water storage tank 36 is exposed to a small amount for a long time, so microorganisms 38 such as algae are likely to breed, and their dead bodies 40 etc. form sludge in the dead water area 39 at the bottom. The water accumulated, causing foul odors and turbidity, and deteriorating water quality.

0004

[Problems to be Solved by the Invention] An object of the present invention is to prevent the formation of dead water areas, which are the main cause of water quality deterioration, thereby preventing the proliferation of microorganisms and the adhesion of limescale to the walls of the water storage tank, and preventing foul odors. To provide a water storage tank that can always supply clean water without turbidity.

[0005]

[Means for Solving the Problems] The gist of the present invention that solves the above problems is as follows: 1) A water intake port is provided at the bottom of a water tank equipped with a water supply port and a water outlet, and spout holes are arranged in a row inside the water tank. Water tank 2) Water supply port, in which a spouting pipe is arranged so that its spouting direction is substantially horizontal, and a means is arranged outside the tank to send water in the water tank sucked out from the water intake port to the spouting pipe. A water intake port is provided at the bottom of the water storage tank, and a spout pipe with a row of spout holes is arranged inside the tank so that the spout direction is approximately horizontal, and each spout hole has a water intake port. A water storage tank 3) provided with a nozzle formed to eject water in a fan shape, and a means for sending water sucked out from the water intake port outside the water storage tank to the spouting pipe.
4) A water storage tank according to claim 1 or 2, characterized in that an activator filled with an activator made of crushed granite blocks is disposed on a water supply path extending from a water intake port to an ejection pipe. 4. The water tank according to claim 1, wherein the water tank is arranged near the bottom surface of the water tank.

[0006]

[Operation] In the water storage tank according to the present invention, water in the water tank comes out from the water intake port, is sent via a pump or the like to a spout pipe arranged inside the water tank, and is jetted out from the spout hole. This jet flow causes a circulation flow in the water in the water tank, and no dead water area is generated in the water tank. Therefore, it is possible to suppress the proliferation of microorganisms such as algae, and it is also possible to prevent scale from adhering to the walls of the water tank.

[0007] Some water storage tanks according to the present invention are constructed such that a nozzle is provided around the spouting hole so that water is spouted out in the form of a fan-shaped water film. In this case, the water spouted from each nozzle generates a water film-like circulating flow throughout the water storage tank. This water film-like circulating flow allows the water in the water tank to be circulated more completely.

[0008] Some water storage tanks according to the present invention are constructed so that after water is taken in from the water intake port, an activator made of crushed blocks of special granite is passed through the water and the water is returned to the water storage tank. According to this activator, due to the action of special granite, organic substances such as phosphorus, which are nutrients for the growth of microorganisms such as algae, are inactivated and inhibited from being absorbed by microorganisms, and at the same time, calcium ions, bicarbonate ions, etc. The water is eluted and the acidic water is neutralized to the alkaline side. This action not only prevents corrosion of water pipes, etc., but also provides so-called hard water that is suitable for drinking.

[0009]

[Embodiment] An embodiment will be explained based on the drawings. First Example (See FIGS. 1 and 2) FIG. 1 is an explanatory diagram showing an outline of this example. In this embodiment, a water intake port 4 is provided at the bottom of a water tank 1 having a water supply port 2 and a water outlet 3, and water taken out from the water intake port is configured to be spouted into the water storage tank 1 via a pump 5. There is. Water tank 1
Inside, two spout pipes 6 are arranged near the bottom of the water tank, and a space is left below the spout pipes 6 through which water can pass. The jet pipes 6 are arranged close to the opposing side walls, and water is jetted out approximately horizontally from the plurality of jet holes 7 provided in the jet pipes 6 toward the adjacent side walls. Furthermore, a nozzle 8 is provided in the jet hole 7, and water is jetted out in a fan shape. FIG. 2 shows an example of nozzle formation. If the spacing between the nozzles is set to about 5 cm so that the jets from adjacent nozzles intersect with each other, the jets from each nozzle will merge to form a water film-like water stream 9. Due to this film-like water flow, the water in the water storage tank 1 generates a vertical circulating flow as shown in FIG. At this time, if the swash plate 10 is provided in front of the jet hole 7, the circulation flow will not be disturbed and it will be more effective.

Second Embodiment (See FIG. 3) A schematic front view of this embodiment is shown in FIG. In this example,
A water intake port 14 is provided in a water storage tank 11 equipped with a water inlet 12 and a water outlet 13, and water taken out from the water intake port 14 is pumped 15.
Water is fed into the activator 18 through the activator 18. The activator 18 is filled with an activator 19 made of special granite, and the action of the activator 19 inactivates organic matter such as phosphorus, which is a nutrient for the growth of microorganisms such as algae. At the same time, it inhibits absorption by microorganisms, increases calcium hardness and the amount of bicarbonate ions, and neutralizes acidic water to alkaline. The results are shown in Table 1. However, the raw water is groundwater.

[Table 1] The water that has passed through the activator 18 that imparts the effects as shown in the above table becomes activated water, and is sent to the spout pipe 16 horizontally arranged near the bottom of the water tank 11, and from the spout hole 17 almost horizontally. It is squirted. A circulating flow is always generated in the water storage tank 11 due to the jet flow, and activated water is provided from the water outlet 13. In the figure, reference numeral 20 is a swash plate, which is provided so that water in the water tank can easily circulate and the water flow is not disturbed.

Third Embodiment (See FIGS. 4 and 5) This embodiment shows an example of the arrangement of the spout pipe 22 and water intake port 23 in the water storage tank 21, and the other configurations are similar to those of the first embodiment or the second embodiment. This may be done as in the embodiment. FIG. 4 is a schematic plan view of the water tank 21 of this embodiment. As shown in the figure, four jet pipes 22 are vertically disposed close to the side wall of the water tank 21, and a water intake port 23 is provided at the center of the bottom of the water tank 22. If configured as in this embodiment, it is possible to generate a vortex flow with a large flow velocity, and foreign matter and dead microorganisms gather at the center of the vortex. The water in the water tank 21 can be easily purified. Of course, one jet pipe is sufficient.

[0012] Without being limited to the embodiments described above, the location and number of the spout pipes and water intake ports may be set as appropriate, and the spacing between the spout holes and the shape of the nozzle of the spout holes may also be changed depending on the capacity and shape of the water tank. All you have to do is choose. Moreover, a bath system that does not require management can be constructed by interposing a hair collector or a heat exchanger on the water supply path from the water intake to the spout pipe. Further, a dust collecting filter, a water purifying layer made of bacteria, etc. can also be provided in the activator described in the second embodiment.

[0013]

[Effects of the Invention] Since the structure is as explained above, no dead water area occurs in the water storage tank according to the present invention. Therefore, not only can the growth of algae etc. in the water tank be suppressed, but also
It is also possible to prevent limescale from adhering to the water tank wall. In addition, by using an activator, the acidic water quality can be neutralized to the alkaline side, which not only prevents water pipes from corroding, but also inactivates nutrients necessary for the growth of microorganisms and prevents the growth of microorganisms. can also be suppressed. Moreover, calcium ions and bicarbonate ions increase in the water due to the action of the activator, resulting in hard water suitable for drinking. It has also been demonstrated that activated water with increased ions has sterilizing power itself, and that foods processed using activated water are less likely to spoil. As a result of the above effects, the water storage tank according to the present invention can always supply clean water without bad odor or turbidity. Of course, an existing water tank can also be modified to form the water tank of the present invention.
