Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water purification activation device and a bath warming device for constantly circulating bath water to purify and activate the bath water and to keep the bath water that has been purified and activated warm.

[0002]

2. Description of the Related Art Conventionally, this type of bath water purifying and activating device circulates the water in the bath tank through the purifier, and purifies and activates the water that is returned to the bath tank as a warmer such as an electric heater. It was heated to keep it at an appropriate temperature so that you can always take a bath.

In the above purifier, for example, granular activated carbon is used as a purifying material and a small amount of barley stone is used as the active material.

[0004]

However, such an apparatus for purifying bath water is difficult to purify organic components such as waste products discharged from the human body, and the purifying activity is not sufficient. There is a problem in that the organic component of water easily causes water spoilage, pollution, bad odor, and the like, and the purifying material and the dirty material must be frequently replaced in a relatively short period of time. Further, since the heat retaining device always keeps the bath water at an appropriate temperature by the electric heater, the electricity cost is high and it is extremely uneconomical as a general domestic bathing device.

The present invention has been made in view of the above points, and an object thereof is to improve the purifying activity and, at the same time, to reduce the fuel cost required for reheating.

[0006]

In order to achieve the above object, the present invention has a bath water purification activation apparatus in which water in a bath tank is constantly circulated through a purification activation material in which a water purifier is enclosed in a purifier by a pump. In the bath water purification activation device, a filter comprising laminated cocoons is laid on the suction side of the purifier.

Further, the bath water heat retaining device is a bath water heat retaining device which is constantly circulated through a purifying active material enclosed in a purifier by a pump and recirculates into the bath tank. The block is surrounded by a block having good heat conductivity, and this block is closely attached to the bottom of the purifier.

[0008]

Since the bath water purifying active device and the heat retaining device according to the present invention are constructed as described above, the water in the bath tank passes through the cocoon layer, which makes it difficult to purify with the conventional purifying active material. The ability to purify organic components such as waste products discharged from the human body can be greatly improved.
Particularly, the effect of making the turbidity and chromaticity of the bath water invariable by long-term use is remarkable, and the life of the purifying active material can be remarkably extended.

Further, since the heat generated by the motor of the pump which is constantly operating is directly transmitted to the bottom of the purifier through the block of the outer shell, the water refluxed in the bath tank is kept in a state where it is extremely difficult to cool it, and when the user takes a bath. It is possible to significantly reduce the fuel cost required for reheating.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a schematic diagram showing the outline of an embodiment of the present invention, and FIG. 2 is an explanatory diagram showing the configuration of a purifying active material housed in the purifier.

As shown in FIG. 1, this apparatus for purifying bath water circulates the water 2 in the bath tank 1 by a pump 3 through a circulation pipe 4 and, in the middle of the circulation pipe 4, a purification active material 5 The purifier 6 enclosing the above is interposed.

As shown in FIG. 2, the purifying active material 5 is a filter 5 in which approximately 1000 cocoons are wrapped on the suction side of the lowermost layer in, for example, a net for a washing machine for preventing twisting and entanglement of laundry.
a is laid as a purification material, and about 20 kg of bakuhanishi is divided into 5 kg portions for convenience of handling, and the first active material 5 b wrapped in a similar net is disposed on the upper portion thereof.
In the uppermost layer, a second active material 5c in which approximately 1.5 kg of calcium-eluting stone having a calcium carbonate content of 95% or more is wrapped in a similar net is provided.

Further, as shown in FIG. 3, the casing 6a of the purifier 6 has a door 6b which can be opened and closed over the entire surface and can be completely sealed by a sealing material (not shown) when closed, and is made of, for example, stainless steel. Such a durable material is usually installed outdoors.

Further, as shown in FIG. 4, the outer peripheral portion of the motor 3a for driving the pump 3 is held by a pair of blocks 7 and 7 having a high thermal conductivity, for example, aluminum, and these blocks 7 and 7 are used as a substrate. 8 (see FIG. 5) is closely attached to the bottom surface of the purifier 6 so that heat generated by the operation of the motor 3a can be transferred to the purifier 6 via the blocks 7 and 7 to keep the internal water warm. To

This embodiment is constructed as described above,
The water 2 in the bath tub 1 flows into the purifier 6 through the circulation pipe 4 by the pump 3 driven by the motor 3a. The water that has flowed into the purifier 6 passes through the filter 5a laid in the lowermost layer, removes minute pollutant components and malodors contained in the water, and then flows into the first active material 5b.

The cocoon constituting the filter 5a has an extremely dense structure and has a remarkably excellent purification ability as compared with conventional granular activated carbon, and is discharged from the human body during bathing, which is difficult to remove with conventional granular activated carbon. It is possible to almost completely remove the waste products and bacteria.

The water thus purified and activated is mixed with the layer of barley stone constituting the first active material 5b and the second active material 5b.
By passing through the layer of calcium-eluting stones that compose c, various minerals and special calcium components are sufficiently replenished and activated, and like the natural hot springs, warms the human body from the core as well as warms the human body from the core. It has a good effect.

[0018] Actually, as a result of requesting a water quality inspection by bringing the bath water after bathing daily for 3 weeks by a family of 6 people with a capacity of about 600 liters, the turbidity was less than 1 degree, permanganese was found. Consumption of potassium acidate 6.7mg / l E. coli was not detected,
It has been proved that it can be sufficiently used as drinking water.

Experiments have also shown that the cocoon constituting the filter 5a has a very high purification ability, so that even if all of them take a bath every day at home of 5 to 6 people, the first and second active materials 5
b, 5c need only be washed once a year, and filter 5a
1 year and the first and second active materials 5b and 5c should be replaced every 5 years.

On the other hand, the water circulated and returned to the bath tank 1 is
It is kept warm by the heat generated from the motor 3a that drives the pump 3. That is, various types of loss generated when the electric energy is converted into mechanical energy by the motor 3a become almost heat and are mostly transmitted directly to the bottom of the purifier 6 through the blocks 7 and 7. Since the motor 3a is always in operation, the water 2 in the purifier 6 is always kept warm.

In Table 1, the case where an exposed type purifier made of stainless steel having a thickness of 2 mm and a capacity of 40 l is used and the pump driving motor is provided away from the purifier is designated as A, and the purification is performed through an aluminum block. The results of measuring the temperature of the bath water at each elapsed time are shown, where B is the case where the bath is in close contact with the bottom.

[0022]

[Table 1]

From Table 1, it can be seen that under the temperature conditions shown in this table, the water temperature after 24 hours has a difference of 9 ° C. between A and B, and after 38 hours has a difference of 12 ° C. It Especially, after 24 hours after bathing every day, in case of A, the difference between the water temperature and the air temperature is only 4 ° C, but in case of B, it is 13
It is also confirmed that the effect of heat retention is great because it is also at ℃.

Therefore, the fuel cost for reheating at the time of bathing is only 1/8 of that of the conventional bath which can be always bathed,
As a result, the fuel cost can be reduced by almost 40% compared to the normal bath in which water is changed every time.

[0025]

As described above, in the apparatus for purifying bath water according to the present invention, since the filter having the cocoons laminated is installed on the suction side of the purifier, the purifying ability is significantly improved. In particular, it becomes possible to purify organic components such as waste products discharged from the human body, which has been considered difficult in the past, and the life of the purifying active material can be remarkably extended.

Further, the bath water heat retaining device is designed to retain the water in the purifier by utilizing the heat generated from the pump driving motor, which has been conventionally radiated to the atmosphere, so that the heat retaining efficiency is extremely high. , It will be possible to significantly reduce the fuel cost required for reheating.
