Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a storage tank device, and particularly to an improvement in a structure for supplying hot or cold water into a storage tank.

[Prior art]

Generally, in a bath at an inn or a public bath, a predetermined amount of hot water is constantly supplied into the bathtub to replenish the amount of hot water that is insufficient due to use or overflow, and to maintain the water temperature at a constant level at all times.

However, in this type of bath, the hot water is usually supplied from above the bathtub, so there is a drawback that only the upper layer of the bathtub is heated, making it impossible to obtain a uniform water temperature. For this reason, the person taking a bath for the first time must stir the water in the bathtub to make the water temperature uniform, but this method is generally not used, and if the water is hot when you put your hand in it, you should stir the water in the bathtub to make it even. It is customary to replenish. However, since the temperature of the water in the lower part of the bathtub is low, the agitation that accompanies bathing causes the temperature of the entire bathtub to drop significantly, making bathing uncomfortable and wasting water and hot water. .

In addition, in this type of bath, it is customary to constantly overflow hot water from the upper edge of the bathtub, and use the overflowing hot water to keep the washing area floor clean and warm. Because the hot water supply port is located above the bathtub, most of the hot water supplied to the bathtub simply overflows.
There is also the problem that the temperature of the water in the bathtub does not rise that much and it is impossible to enter the washing area due to the overflowing hot water.

In addition, even if new hot water is supplied into the bathtub from the supply port, most of it simply overflows, so the old, dirty hot water in the bathtub is rarely replaced, and the hot water in the bathtub becomes dirty in a short period of time. There is also the problem of putting it away. Generally, in a bath that accommodates about 20 people,
It is said that when the total number of bathers in a bathtub is around 4 to 5 people per day, the hot water in the bathtub becomes dirty and the entire amount of hot water must be replaced. Therefore, the bathtub must be cleaned as frequently as during busy times, and a large amount of hot water is wasted.

In addition, in home baths, the hot water outlet is usually provided on one side wall in the longitudinal direction of the bathtub, but even in this case, the hot water discharged from the outlet is directed to the baffle plate in front of it. The problem is that the water rises immediately upon contact, and the temperature of the water in the bathtub is not uniform.

Furthermore, the amount of hot water in a home bath is small, so the temperature drops in a relatively short period of time, but in this case, the burner etc. must be relit even while taking a bath. However, even though there is a baffle plate in front of the discharge port, the hot water that comes into contact with the baffle plate does not diffuse and rises at almost the same temperature, making it impossible to approach the baffle plate. For this reason, even though the bathtub itself is of sufficient size, it is extremely cramped when multiple people, such as parents and children, are in the bathtub.

[Purpose of invention]

The present invention was developed in view of the current situation, and it is possible to equalize the temperature of hot water in a storage tank such as a bathtub or water tank, and to promote the replacement of old hot water in the storage tank with new hot water from the outlet. To provide a storage tank device whose interior can always be kept clean.

[Summary of the idea]

In the present invention, an ejection pipe is arranged along the bottom surface of the storage tank, and a plurality of pores are bored in the ejection pipe at arbitrary intervals in the axial direction, and the ejection pipe has the following features:
A supply pipe that leads hot or cold water from the discharge port to the spout pipe is connected, and the inside of the storage tank is stirred by the hot water jetted almost uniformly from each of the pores, thereby achieving uniform temperature and purification within the storage tank. It is characterized by being able to achieve the following.

[Example of idea]

The present invention will be explained below with reference to the drawings.

1 and 2 show a first embodiment of the present invention, and in the figures, 1 is a bathtub in an inn or a public bath. The bathtub 1 has, for example, a horizontally elongated rectangular shape when viewed from above, and a square ring-shaped ejection pipe 2 is disposed at the peripheral edge of the bottom surface thereof. Fresh hot water is supplied to the spout pipe 2 from above the bathtub 1 in the direction of arrow A shown in FIG.
It is designed to be constantly supplied via.

As shown in FIG. 1, the spout pipe 2 includes unit pipes 2a and 2b that correspond to the short side of the bathtub 1, unit pipe 2c that corresponds to the long side, and a unit pipe 2c that corresponds to the long side. L-shaped joints 4 are removably attached to both end portions of the unit tubes 2a, 2b, and the unit tubes 2a, 2b, 2e are provided with unit tubes 2d, 2e.
c, 2d, and 2e are attached so that they can be rotated around the axis. Further, the opposing ends of both unit pipes 2d and 2e are connected to each other through a removable T-shaped joint 5 so as to be rotatably adjustable around the axis.
The lower end of the supply pipe 3 is detachably connected to the remaining joint.

Each of the unit pipes 2a connected in this way,
2b, 2c, 2d, and 2e, a large number of pores 6 are bored at approximately equal intervals in the axial direction and at the same position around the axis, as shown in FIGS. 1 to 3. Each unit pipe 2a, 2b, 2c, 2d, 2e is
Normally, each of the pores 6 is set to face the inside of the bathtub 1 so that the opening direction is horizontal.

On the other hand, as shown in FIGS. 1 and 2, the supply pipe 3 is provided with a funnel-shaped hot water receptacle 3a at its upper end.
That is, it is located above the hot water level W of the bathtub 1. And new hot water A supplied to this hot water receiving part 3a
are each unit pipe 2a of the ejection pipe 2 via the supply pipe 3,
2b, 2c, 2d, and 2e, respectively, and is supplied almost uniformly into the bathtub 1 from each pore 6.

Next, the effect will be explained.

When fresh hot water A is supplied from the hot water receiving part 3a at the upper end of the supply pipe 3, this new hot water A pushes down the fresh hot water filled in the supply pipe 3 by the same amount and pushes it out to the spout pipe 2 side. As a result, the hot water filling the spout pipe 2 is supplied into the bathtub 1 from each pore 6.

By the way, the hot water supplied from the supply pipe 3 to the spout pipe 2 exchanges heat with the hot water in the bathtub 1 while flowing down inside the supply pipe 3, and the temperature of the hot water slightly decreases.
The temperature is higher than that of the hot water in the spout pipe 2. Therefore, the hot water from the supply pipe 3 is distributed to each unit pipe 2 as shown in FIG.
a, 2b, 2c, 2d, and 2e so as to spread evenly throughout the bathtub 1, and then be pushed out by the hot water supplied from the supply pipe 3 and supplied into the bathtub 1 from each pore 6. Thereby, hot water of approximately the same temperature is uniformly supplied into the bathtub 1 from each pore 6 regardless of the distance from the supply pipe 3.

The hot water uniformly discharged into the bathtub 1 from each pore 6 flows along the bottom of the bathtub 1 as shown in Fig. 4, and then rises due to the difference in specific gravity and overflows. Since surrounding hot water is drawn in, the hot water in the bathtub 1 is stirred.

As a result of this stirring, the temperature of the water in the bathtub 1 becomes uniform, and only the upper layer does not reach a high temperature.
In addition, the hot water discharged from the pores 6 stirs up the dust that had settled at the bottom of the bathtub 1 and naturally floats to the surface, and the floating dust is discharged to the outside together with the overflowing hot water. Since the dust floating in the bathtub 1 is also discharged to the outside, the inside of the bathtub 1 can be kept clean at all times.

In addition, if the new hot water A supplied to the hot water receiving part 3a at the upper end of the supply pipe 3 is a hot spring, the new hot water A may contain a large amount of ingredients such as scale and slime, and in some cases may contain small stones etc. However, while the fresh hot water A passes through the supply pipe 3 and the spout pipe 2, these components adhere to the inner surfaces of both pipes 2 and 3 and are removed, reducing the amount carried into the bathtub 1. can be reduced. Further, foreign objects 7 such as pebbles are also settled and removed at the bottom of the jet pipe 2, as shown in FIG. 3, and are not carried into the bathtub 1.

In addition, fresh hot water A is once stored in the supply pipe 3 and the spout pipe 2 and then supplied to the bathtub 1 from the small hole 6. It has the effect of keeping you warm.

Furthermore, by bringing the sole of the foot or the like close to the pores 6, the hot water discharged from the pores 6 can produce the effect of acupressure or moxibustion.

Further, since the ejection pipe 2 and the supply pipe 3 have a structure that can be separated, they can be easily cleaned using a wire brush or the like. Further, when cleaning the inside of the bathtub 1, the pipes 2 and 3 can be easily taken out.

5 and 6 show a second embodiment of the present invention, in which the device is applied to a bathtub 11 for domestic use.

That is, as shown in FIG. 5, a square ring-shaped jet pipe 12 is disposed around the bottom of the bathtub 11, and the jet pipe 12 has an upper end connected to a hot water discharge port 10.
The lower end of the supply pipe 13 is connected to supply hot water to the spout pipe 12.

As shown in FIG.
, a unit pipe 12c that matches the short side, and unit pipes 12d, 12 whose total length dimension almost matches the short side.
e, both unit pipes 12a, 12b
At both end positions, L-shaped joints 14 having the same configuration as the L-shaped joint 4 in the previous embodiment are attached. Further, a T-shaped joint 15 having the same configuration as the T-shaped joint 5 in the embodiment described above is installed between the opposing ends of both unit pipes 12d and 12e, and the remaining joint portion of this T-shaped joint 15 is provided with the The lower end of the supply pipe 13 is detachably connected. The upper end of this supply pipe 13 is connected to the sixth
As shown in the figure, it is connected to a hot water outlet 10 that opens on the inner wall surface of the short side of the bathtub 11 and has a baffle plate 10a at the front via an L-shaped joint 16 that surrounds the hot water outlet 10.

In addition, each of the unit pipes 12a, 12b, 12c, 1
2d and 12e, a large number of pores (not shown) having the same configuration as the pores 6 in the embodiment described above are bored toward the inside of the bathtub 11.

The hot water in the bathtub 11 poured out from the spout (not shown) is guided to a heating means (not shown) such as a burner, heated there, and then flows into the bathtub 11 from the hot water spout 10. Supplied. This hot water is poured into the L-shaped joint 1 as shown by the arrow in Figure 6.
6 to the supply pipe 13 and further to the ejection pipe 12. And each unit pipe 12a, 12
Pores b, 12c, 12d, 12e (not shown)
The water is almost evenly supplied into the bathtub 11 from the water.

As explained above, this embodiment also provides the same effects as those of the previous embodiment. However, in the case of this embodiment, the hot water discharged from the hot water outlet 10 is not fresh water, and the hot water in the bathtub 11 is not always overflowed, so the effect of keeping the inside of the bathtub 11 always clean cannot be expected to be that great. . However, great practical effects can be obtained, such as being able to light a burner or the like even while taking a bath, and not having to feel cramped.

Note that in both of the above embodiments, the ejection pipes 2, 12
Although the explanation has been given on a ring-shaped arrangement along the bottom periphery of the bathtubs 1 and 11, it is also possible to arrange them in a U-shape along three sides of the bathtubs 1 and 11, or in an L-shape along two sides. The desired effect can be expected even if it is placed in a bar shape along only one side. In addition, if the bathtub is too wide, it may be arranged not only around the bottom edge of the bathtub but also over the entire bottom area.
Further, the ejection pipes 2 and 12 do not necessarily need to be in contact with each other as long as they are arranged along the bottom surfaces of the bathtubs 1 and 11, and may be arranged at a slightly upper position.

Furthermore, in both of the above embodiments, the case where the pores 6 are oriented horizontally toward the inside of the bathtubs 1 and 11 has been described, but the desired effect will not be achieved no matter where the pores 6 are located around the axis. Furthermore, even when the pores 6 are not provided at equal intervals in the axial direction, substantially the same effect as in the case where the pores are provided at equal intervals can be obtained.

Furthermore, although both of the above embodiments have been described with reference to the case where the present invention is applied to a bathtub, the present invention can also be applied to other storage tanks such as water tanks and ponds in addition to bathtubs.

FIGS. 7 and 8 show a third embodiment of the present invention that takes the above points into consideration, and will be described below.

In the figure, 21 is a storage tank filled with water, such as a water bath or an aquarium. At the bottom of this storage tank 21, there are six unit pipes 22a arranged in parallel and each unit pipe 22a.
A connecting pipe 22 whose one end is removably connected via an L-shaped joint 24 and a T-shaped joint 25.
A jet pipe 22 having a comb shape as a whole is disposed from the connecting pipe 22b, and a T-shaped joint 2 is connected to the connecting pipe 22b.
The lower end of the supply pipe 23 is removably connected through the pipe 6, and new cold water is sent to the storage tank 21 through the supply pipe 23.

A water sealing cap 27 is attached to the free end of each unit pipe 22a, and each unit pipe 22a has a cap 27 for water sealing.
As shown in FIG. 7, a large number of pores 28 are formed at required intervals on the upper surface of 2a.

Thus, the new cold water sent through the supply pipe 23 is transferred to each unit pipe 22 through the connecting pipe 22b.
a, and is supplied almost equally into the storage tank 21 from each pore 28. As a result, the same effects as those of the above embodiments can be expected.

In addition, when applying this to a water bath, unit pipe 2
It is possible that 2a gets in the way when taking a bath,
In this case, a groove may be provided at the bottom of the water bath and the unit pipe 22a may be placed inside the groove, or a screen may be placed at the bottom of the water bath.

[Effect of idea]

As explained above, the present invention includes disposing an ejection pipe along the bottom surface of the storage tank, and drilling a plurality of pores in the ejection pipe at arbitrary intervals in the axial direction.
In addition, since a supply pipe is connected to the spouting pipe, which leads the hot water or cold water from the discharge port to the spouting pipe, the inside of the storage tank is stirred by the hot water or cold water spouted from the pores to equalize the temperature. I can do it.

In addition, if the tank has a structure in which new hot or cold water is supplied from the discharge port and the hot or cold water in the tank overflows, the inside of the tank is kept clean at all times by discharging the dust inside the tank to the outside of the tank. be able to.
