DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a circulating bath device which can be used at any time by constantly purifying hot water in a domestic or commercial bathtub while maintaining a constant temperature and amount of hot water.
Specifically, it relates to a purification device.

[0002]

2. Description of the Related Art Generally, in this type of circulating bath device, a bathtub is connected in series to a heating device, a purifying device, a circulation pump, etc. by a pipe. The controller constantly drives the circulation pump to circulate the hot water in the bathtub to the purifying device to purify the hot water. At this time, the heating device controls the temperature of the hot water and the water level in the bathtub. Therefore, in this apparatus, when water is heated to a relatively high temperature, organic substances are easily generated and dirty water is treated easily, and various impurities and bacteria are mixed in the hot water when the bath is used. Therefore, the purifier is required to have a capability of decomposing organic substances in hot water, removing impurities, and sterilizing the hot water to activate the hot water at all times.

Conventionally, as for the above-mentioned purification device, there is a prior art disclosed in, for example, Japanese Utility Model Publication No. 3-26896. In this prior art, the filter of the purifying device has a double cylindrical outer cylinder and an inner cylinder by a net, a large number of porous ceramic balls are packed in the outer cylinder, and the inner cylinder is filled with barley stone or the like. It is composed of many active materials. Then, the ceramic ball adsorbs dirt components in water and purifies them by the action of aerobic microorganisms, and further activates them by contact with an active material and further purifies them. In addition, in the water inflow section at the bottom of the filter, the water that has flowed into the purification chamber once hits the outer wall of the drainage section and is dispersed.
It has been shown to be configured to rise in a uniformly distributed state.

[0004]

By the way, in the case of the above-mentioned prior art, although the filter of the purifying device is composed of a double cylindrical outer cylinder and an inner cylinder, it is made compact. Increases the capacity of a single component. Therefore, it requires a lot of installation space, which is disadvantageous for home use and increases the pump capacity. There are 2 bakuhan stones inside the ceramic bowl.
Although they are arranged in a heavy manner, it is difficult for water to effectively pass between them, and the purification efficiency is low. Furthermore, in the filter,
Since it is a structure that disperses water by colliding with the outer wall of the drainage part,
Although the water flow is uniformly distributed, there is a problem in that water cannot pass through the layer such as a ceramic ball in the axial direction unevenly and cannot be effectively purified.

The present invention has been made in view of this point,
Its purpose is to effectively use science ceramics with strong redox power to improve purification and activation performance, to make installation easier, and to increase purification efficiency by spirally raising water with a filter. To do.

[0006]

The present invention relates to a circulating bath apparatus in which water in a bathtub or hot water is communicated so as to circulate in the bathtub via a purifying device and a heating device by driving a circulation pump.
In such a circulating bath device of the present invention, the purifying device is divided into a first filter provided with a large number of ceramic balls and a second filter provided with a large number of science ceramics having a strong redox power. It is divided and placed. Further, the first filter is provided with an inflow port for inflowing water or hot water by a pump negative pressure and an outflow port for outflowing water or hot water on the outer periphery of the cylindrical body, and the inflow port is circumferentially arranged with respect to the outflow port. It is arranged to be shifted in the direction.

In the present invention, the first and second filters may be provided with a purifying device and circulate water or hot water, and can be applied to a purifying device for drinking water other than the bath device. The first and second filters can be constructed not only individually but also as a single body only inside each separately.
The order and the like may be arranged arbitrarily. Other than that, barley stone, other filter materials, and active materials may be mixed in the first filter provided with ceramic balls and the second filter provided with science ceramics.

[0008]

According to the present invention having the above-mentioned structure, the water or hot water in the bathtub is always circulated in the bathtub by the drive of the circulation pump through the purifying device and the heating device. At this time, the hot water comes in contact with the ceramic balls of the first filter. Purified. In addition, the hot water flows into the second filter arranged separately, and by touching this science ceramics, it is effectively purified and activated electrically and chemically due to its strong redox power. . Further, the first filter is provided with an inflow port for inflowing water or hot water by a pump negative pressure and an outflow port for outflowing water or hot water on the outer periphery of the cylindrical body, and the inflow port is circumferentially arranged with respect to the outflow port. Since they are arranged so as to be displaced in the direction, the hot water that has entered the first filter rises while spirally rotating. As a result, the hot water effectively contacts the ceramic balls in the first filter, and the hot water can be effectively filtered.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, the overall configuration of the circulating bath device will be described. Reference numeral 1 is a bathtub installed indoors,
A pipe 2 is provided at the bottom of the bathtub 1 so that water or hot water A can be taken out.
Is communicated. The outdoor purifying device 3 is configured by separating and dividing into a first filter 4 having a large number of ceramic balls and a second filter 5 having a large number of science ceramics. Then, the pipe 2 from the bathtub 1 is connected so that the hot water A flows into the first filter, and the hot water A flows from the first filter 4.
The pipe 6 that flows out of is connected to the suction side of the circulation pump 7.

The pipe 8 on the discharge side of the circulation pump 7 is connected to a heating device 9 such as a gas boiler, and the pipe 10 from the heating device 9 is connected to the second filter 5. And the second
The pipe 11 from the filter 5 is connected to the upper part of the bath 1 to form a circulation path for water or hot water A.

As shown in FIGS. 2A and 2B, the first filter 4 has a cylindrical body 20 having a bottomed cylindrical shape.
The lid 21 is covered and sealed with packing or the like so as to keep airtightness. A drain chamber 23 is formed by a bottom plate 22 below the inside of the cylindrical body 20, and a pipe 8 to the circulation pump 7 is connected to an outlet 24 provided on the outer periphery of the drain chamber 23.
A thin drainage pipe 2 communicating with a drainage chamber 23 is provided at the center of the bottom plate 22.
5 is erected so that the pump negative pressure acts on the cylindrical body 20.

An annular mesh cylinder 26 is installed around the drainage pipe 25 on the bottom plate 22 with a predetermined gap, and a large number of ceramic balls 27 are packed inside the mesh cylinder 26. An inflow port 28 communicating with the pipe 2 from the bathtub 1 is provided on the outer periphery of the cylindrical body 20 slightly higher than the bottom plate 22, and the inflow port 28 has a circumference around the outflow port 24 as shown in FIG. 2B. It is arranged so as to be displaced in one direction, and this displacement enables the molten metal A to rise in the layer of the ceramic balls 27 while rotating in a spiral shape.

The second filter 5 includes a large number of science ceramics 31 inside a closed cylindrical body 30 of a predetermined size.
It is configured by inserting. Science ceramics 31
Is disclosed in Japanese Examined Patent Publication No. 4-28794,
It is obtained by coating semiconductor balls such as iron oxide, alumina, and carbide with titania (TiO2), which is a semiconductor, and baking the balls to generate a strong redox power. Due to this strong redox power,
It has the ability to electrically prevent the generation of rust and the adhesion of scale, and to chemically decompose organic matter in water or hot water A to activate it so as to suppress the growth of bacteria.

Explaining the control system, a temperature sensor 35 for detecting the temperature of water or hot water A in the pipe 2 from the bathtub 1.
However, a water level sensor 36 for detecting the water level is provided in the bathtub 1. The signals of these sensors are input to the controller 37 for processing, and the output signals of the controller 37 are used to output the circulating pump 7
Drive at all times. When the temperature of the hot water A drops below the set value, the heating device 9 is activated, and when the water level drops, the supply pipe 3
8 is configured to open valve 39.

Next, the operation of this embodiment will be described. When the circulation pump 7 is driven by the controller 37, the bath negative pressure is passed through the first filter 4 whose pump negative pressure is closed.
And the hot water A in the bathtub 1 flows into the inside of the tubular body 20 from the inlet port 28 of the first filter 4. At this time, in the first filter 4, the inflow port 28 is circumferentially displaced with respect to the outflow port 24, so that the hot water A flowing from the inflow port 28 by the pump negative pressure at the upper end of the drain pipe 25. However, it is forcibly turned in one of the rotation directions having a short distance between the two, and a rotational force is applied.

Then, the hot water A flowing into the tubular body 20 is transferred to the mesh tube 2
6 rises while rotating spirally in a layer of porous ceramic balls 27 inside 6 from bottom to top. Because of this, hot water A
Of the ceramic balls 27 can be efficiently and repeatedly passed over the entire axial direction of the layers of the ceramic balls 27, and can smoothly pass therethrough. Therefore, the dirt of the hot water A is filtered in the entire axial direction of the layer of the ceramic balls 27 and is effectively purified by the aerobic microorganisms.

The hot water A passing through the ceramic balls 27 is
Collected by the central drainage pipe 25, it enters the drainage chamber 23 and is sucked into the circulation pump 7 from the outlet 24 of the drainage chamber 23. Then, the hot water A discharged from the circulation pump 7 flows into the heating device 9. At this time, when the water level of the bathtub 1 is low, the valve 39 is opened by the signal of the water level sensor 36 to replenish the water, and the temperature of the hot water A is increased. When the temperature is low, the heating device 9 is activated by the signal of the temperature sensor 35 to be heated.

The hot water A that has passed through the heating device 9 flows into the second filter 5 and passes while touching a number of science ceramics 31. Therefore, the hot water A has an electrically peculiar characteristic due to the strong redox power of the science ceramics 31 this time, and this influence affects the bath 1 to prevent the adhesion of the hot water stain, and similarly to the pipes to prevent rust. Generation and scale adhesion are prevented. In addition, the organic substances in water or hot water A are chemically decomposed, the growth of bacteria is suppressed, and the water quality is further activated. Then, the water or hot water A activated by the second filter 5 is returned to the bathtub 1, and thus, by circulating the hot water A in the bathtub 1 at a predetermined speed, the bathtub 1 is always purified and activated. The hot water A of the predetermined amount and temperature is stored,
It can be used at any time.

In addition to the ceramic balls 27, barley stone or the like may be mixed in the net cylinder 26 of the first filter 4. The arrangement of the first filter 4 and the second filter 5 may be other than that in the embodiment, and the second filter 5 may be installed in the circulation system path including the bathtub 1 in two positions.
It is also possible to arrange more than one.

Referring to FIG. 3, another embodiment of the first filter 4 will be described as a second embodiment of the present invention. On the bottom plate 22 inside the tubular body 20, mesh cylinders 26 and 40 are arranged in two layers vertically, and ceramic balls 27 are inserted into the mesh cylinder 26 of the lower stage and barley stones in the mesh cylinder 40 of the upper stage. 41 is inserted. Further, the inflow port 28 is the outflow port 2 as in FIG.
4 are arranged circumferentially offset. Otherwise,
The structure is exactly the same as in FIG. 2, and the same portions are denoted by the same reference numerals and the description thereof is omitted.

Therefore, in this embodiment, the hot water A flowing into the cylindrical body 20 from the inflow port 28 first rises while spirally rotating in the layer of the ceramic balls 27, and then in the layer of the barley stone 41. It rises while spirally rotating. Therefore,
Both the purification by the ceramic balls 27 and the activation by the barley stone 41 are performed with high efficiency.

Referring to FIG. 4, as a third embodiment of the present invention, a case where the purifying device 3 is made compact will be described. The bathtub 1 in this case is used by, for example, a small number of people for home use, and the first and second filters 4 and 5 of the purifying device 3 make the inside of the single cylindrical body 45 like a net. Partition 4
It divides into two chambers 47 and 48 at 6 and these chambers 47 and 4
8 ceramic balls 27 and science ceramics 3
1 is inserted in each. Then, the bathtub 1 enters the bathtub 1 via the purifying device 3, the circulation pump 7, and the heating device 9,
The hot water A is communicated so as to circulate. Also in the third embodiment, the inflow port of the first filter 4 and the outflow port of the purification device 3 corresponding to the outflow port of the first filtration device constituting the purification device 3 are arranged in the circumferential direction. It is staggered.

Therefore, in this embodiment, when the hot water A having a relatively small amount of dirt in the bathtub 1 is repeatedly circulated by the circulation pump 7, the hot water A and the ceramic balls 27 adjacent to the purifying device 3 and the science ceramics. 31 is continuously contacted and purified to obtain sufficiently good water quality. Further, the entire apparatus becomes very compact, and the installation, cost, etc. become more advantageous.

[0024]

Since the circulating bath device of the present invention is constructed and operates as described above, it is possible to effectively purify and activate the water or hot water in the bathtub by the performance of the ceramic balls and science ceramics. By dividing the two filters, individual parts can be made compact, and installation is advantageous in terms of space and piping.

Further, the first filter is provided with an inflow port for inflowing water or hot water by a pump negative pressure and an outflow port for outflowing water or hot water on the outer periphery of the cylindrical body, and the inflow port is set to the outflow port. Since they are arranged so as to be displaced in the circumferential direction, water and hot water can rise while rotating spirally in a layer such as a ceramic ball, which improves the purification efficiency in the entire axial direction of the ceramic ball or the like. You can do it, and the flow of hot water will be improved. The structure is simple because there is only a positional relationship between the inflow port and the outflow port.
