The microorganisms, etc., in the hot water are then sterilized and malodors are removed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises a filtering device for filtering hot water, an activating tank for purifying the hot water, a heating device for heating the hot water, and the like. Relates to a circulating bath water supply device which circulates between a filtration device, an activation tank, a heating device, and the like.

[0002]

2. Description of the Related Art As is well known, home baths used in Japan are generally classified into a reheating type and a dropping type. The reheating type bath is composed of a bathtub and a heater, and the bath water is naturally circulated between the bathtub and the heater to heat the bath. On the other hand, the drop-in bath is
For example, hot water heated to a predetermined temperature is poured into a bathtub from a water heater or a hot water storage tank. The drop-in bath has the advantage that the bath water is kept relatively hygienic because fresh water heated to a predetermined temperature is poured as appropriate. However, when the temperature of the hot water drops, even if the hot water overflows from the bathtub, new hot water must be added, which is uneconomical. Moreover, because it is uneconomical,
It is not suitable as a bath where you can enjoy bathing at any time.

On the other hand, in the case of the reheating type bath, the bath water having a lowered temperature is heated while being circulated, so that it is not necessary to add new high temperature hot water unlike the drop-in type bath. It is economically advantageous. Therefore, it is suitable as a bath where you can enjoy bathing at any time. However, as the number of baths increases, the bath water becomes contaminated with human dirt, oil, human hair, etc., and other bacteria also propagate, making it unsuitable for bathing. Therefore, a hot-water reheating device equipped with a filter for filtering the hot-water bath is disclosed in, for example, Japanese Utility Model Laid-Open No. 56-15938.
Proposed by the issue. This reheating device is equipped with a circulation pump, a heater, and the like, in addition to the filter. Therefore, when the circulation pump is activated, the bath water is filtered and
It is possible to circulate between the hot water and the like, while the impurities in the bath water are filtered with a filter and heated with a heater.

A bath water purifying device is also disclosed, for example, in Japanese Examined Patent Publication No.
Proposed by No. 7-17564. This bath water purifying apparatus is also provided with a pump for forcedly circulating hot water, a filtration filter, and the like together with the water activation filtration apparatus. Therefore, when the pump is started and the bath water is circulated, the bath water is purified by the bath water purifying device during that time, and relatively large dirt, human hair and the like are removed by the filter. Further, JP-A-58-295 proposes a purification method of treating water for breeding aquatic animals, pool water and the like with ozone.

[0005]

Since the above-mentioned reheating device also has a filter and also has a heater, the bath water is circulated so that relatively large impurities such as human hair and dirt in the bath water are circulated. There is an advantage that it can be repeatedly used by removing with a filter and heating with a heater. However, although the bath water contains microorganisms, oils, etc., these microorganisms cannot be removed by the filter. And since the bath water is kept at an appropriate temperature, the microorganisms often reproduce or cause a chemical reaction to give off a bad odor. Therefore, the fact is that various bath additives are mixed in to neutralize the bad odor. However, even if a bath agent is used, it does not disappear, only by neutralizing the odor in the bathtub, the fat in the bathwater, etc.
In addition, there is a problem with hygiene, so after all it must be discarded.
It cannot be used for a long period of time.
When the bath water is discarded and new water is poured, a large amount of energy is consumed for heating up to a predetermined temperature, and there is also a problem of wasting water. Recently, the standard of living has improved and the number of people who enjoy bathing at any time has increased, but it takes some time to warm up to a predetermined temperature when water is replaced, and it is not possible to take a bath when you want to take a bath. There is also the drawback of not being able to satisfy these people.

Further, since the bath water purifying apparatus proposed by Japanese Patent Publication No. 57-17564 is equipped with a water activation filtration apparatus, ammonia and the like in the bath water due to, for example, bacteria growing there. Although it is decomposed, it cannot decompose organic substances having a relatively large molecular weight such as human dross. In particular, when the number of baths increases and the amount of organic substances increases, the bacteria cannot be treated, and the bath water eventually decomposes with these organic substances. That is, aerobic bacteria grow using the dissolved oxygen dissolved in the bath water, but since the dissolved oxygen amount in the bath water is generally small, the growth of the bacteria is not sufficient and the bacteria cannot be treated.

As described above, a device for sterilizing microorganisms and the like in the bath water, for example, a sterilization device in which ozone gas is injected into the bath water, is disclosed in the above-mentioned Japanese Patent Laid-Open No. 58-295. As is known, it is well known in the art. According to this sterilizer, microorganisms and the like in the bath water can be sterilized by the strong oxidizing power of ozone, so that the sanitary problem can be solved to some extent. However, since the ammonia and the like in the bath water are not treated, they start to give off a bad odor, and ozone gas alone cannot be used repeatedly for a long period of time.

As described above, the reheating device equipped with a filter for removing contaminants in the bath water, the bath water purifying device having the water activated filtration device, and the ozone sterilization device are individually provided. Is known. And each device has its own effect. However, as mentioned above, these individual devices do not provide a bath water that can be recycled and reused for a long period of time.
Therefore, it is an object of the present invention to provide a bath water circulation supply device that can repeatedly use the bath water for a long period of time. Specifically, the bath water is filtered, and more thoroughly purified, and sanitarily sanitized.
It is an object of the present invention to provide a circulating bath water supply device that is deodorized and can be used repeatedly for a long period of time as a result.

[0009]

In order to achieve the above object, the present invention is a combination of a filter device, an activation tank, a heating device and an ozone generator. By combining them, the effects exhibited by the individual devices can be obtained, and new effects peculiar to the present invention can be obtained to achieve the above-mentioned object. That is, the present invention, in order to achieve the above object, comprises a filtration device for filtering bath water, an activation tank for purifying the bath water, a heating device for heating the bath water, and an ozone generator, and a circulation pump. When the hot water is driven, the hot water in the bath circulates between the filtration device, the activation tank, the heating device, etc., during which the hot water is filtered, purified, and then heated. A bathtub hot water circulation supply device, wherein the activation tank comprises:
Activated stones such as barley stone, sulfur stone, obsidian, rhyolite, and unweathered pearlite are filled in one or a mixture of two or more kinds, and the ozone gas generated by the ozone generator is bathed with air. It is designed to be poured into hot water.

[0010]

[Operation] The circulation pump is started. Then, the bath water is forcibly circulated among the filtration device, the heating device, and the activation tank. While being circulated, a relatively large amount of human dirt, human hair, etc. in the bath water are removed by the filtration device. The bath water is heated by the heating device. In the activation tank, decomposes bacteria or other organic matter that breed in other activated stones that are filled in the activation tank, such as barley stone, sulfur stone, obsidian, rhyolite, and unseasoned pearlite. Then, bacteria that obtain energy for life purify the bath water by decomposing organic substances such as ammonnia that cause the bath water to rot. Furthermore, the bath water is ion-exchanged by these activated stones, and minerals such as magnesium and zinc or active ingredients such as calcium and sodium are dissolved in the bath water, and the hydrogen ion concentration of the bath water is adjusted to around neutral. To be done. This imparts a bathing effect to the bath water. The ozone gas generated by the ozone generator is appropriately injected into the bath water together with air. Then, the microorganisms in the bath water will be sterilized,
The stench is deodorized. Ozone gas becomes dissolved oxygen in the bath water and is contained in a large amount, which helps the aerobic bacteria growing in the activation tank to propagate and further promotes purification by the bacteria. Furthermore, ozone decomposes organic matter with a large molecular weight that bacteria cannot decompose,
The bacterium then treats the decomposed organic matter. As a result, the bath water is always kept clean.

[0011]

EXAMPLES Examples in which a controller for controlling the start and stop of the heater and the ozone generator are provided will be described below. Referring to FIG. 1, the bathtub apparatus according to the present embodiment,
Bath 1, filtration tank 5 as filtration means, and pump 3
At first glance, it can be understood that the heater 6 as a heating means and the active tank 7 are roughly configured, and these are sequentially connected in series by a conduit such as a forward pipe 10 and a return pipe 9. . These devices are provided in the case 2 outside the bathtub 1.
It is also easily understood that the device is made compact by being housed inside.

The bathtub 1 and case 2 have a return pipe 9 and a forward pipe 10.
The return pipe 9 is connected to the filtration tank 5, and the outward pipe 10 is connected to the active tank 7. Therefore, the hot water in the bath 1 is first introduced into the filtration tank 5 to remove contaminants by the drive of the pump 3 and then heated by the heater 6, as shown by the arrow, and the active tank 7 is heated.
After the hot water is activated in, the return pipe 10 returns to the bath 1.

As shown in FIG. 2, the filtration tank 5 is composed of a tubular body 51 having a tubular shape. A lid 52 is attached to the upper surface of the tubular body 51 to hermetically seal the inside of the tubular body 51. An introduction pipe 54 connected to the return pipe 9 is attached to a side surface of the cylindrical body 51, and an outlet pipe 53 is axially inserted into the cylindrical body 51 from a lower portion. The opening of the outlet pipe 53 faces the upper space of the cylinder.
Therefore, the bath water introduced into the tubular body 51 is not discharged from the outlet pipe 53 until the tubular body 51 is filled with the bath water.
Around the outlet pipe 53, sponge-like filter cloths 55a, 55b, 55c made of polyurethane or the like are concentrically laminated in three layers. The mesh of the filter cloths 55a, 55b, 55c becomes smaller toward the inner layer, and the contaminants are appropriately collected by the filter cloths 55a, 55b, 55c according to the diameter and length. As described above, since the entire circumferential surface of the filter cloths 55a, 55b, 55c is used for filtration, the collecting area is large, and the filter cloths 55a, 55b, 55c may be clogged even when used for a long time. There is no such thing.

A suitable heater such as a gas combustion heater or an electric heater can be applied to the heater 6, but a ceramic can also be applied. Heat using ceramic
In the case of Ta, a rod body made of zirconia-based ceramic is arranged around the heater. The far-infrared rays are radiated from the zirconia-based ceramic by the heat from the heater, and the hot water is heated by the far-infrared rays. Hot water heated or heated by far infrared rays has a greater heat retaining effect than hot water heated by general heating means, and the bathing effect is increased.

The active tank 7 is filled with one or more kinds of active stones such as barley stone, sulfur stone, obsidian, rhyolite, and unweathered pearlite, and hot water is used in the active tank. After passing through 7, the bacteria that propagate in the tank 7 and decompose the other nourishing bacteria, that is, the organic matter to obtain the energy of life, decompose the organic matter, for example, ammonnya that causes the bath water to rot. To purify the bath water. Further, the hot water is ion-exchanged, and at the same time, minerals such as magnesium and zinc or effective components such as calcium and sodium are dissolved in the hot water, and the hot water is adjusted to have a weakly alkaline hydrogen ion concentration. This imparts a bathing effect to the bath water.

On the outer wall of the case 2, a conventionally known ozone generator 8 is attached as a sterilizing means. An air pipe 81 is connected to the ozone generator 8. The tip of the air pipe 81 is connected to the forward pipe 10 via a backflow prevention means, that is, a trap portion 82. Therefore, when the pump 3 is driven and the bath water is ejected from the outward pipe 10,
Ozone is mixed with the air into the bath water due to the negative pressure generated when the gas is ejected, so that microorganisms and the like in the bath water are sterilized and deodorized. As a result, the bath water is always kept clean. As described above, since it is not necessary to use chlorine for sterilizing the bath water, irritation is small and it can contribute to health maintenance. In this case, ozone is jetted into the bathtub 1 together with the bath water to directly hit the human body of the bather to sterilize the skin, so that the skin can be cleaned. Note that FIG.
Reference numeral 82 indicates a reverse trap portion formed by bending a part of the air tube 1. The trap portion 82 is bent so as to be higher than the surface of the hot water in the bathtub 1 and prevents the hot water from flowing back into the ozone generator 8.

In such a bath water circulation supply device, the heater 6 and the ozone generator 8 are controlled to start and stop by a single controller 11. The controller 11 is formed separately from the case 2, is appropriately installed inside or outside the bathroom, and is electrically connected to the heater 6 and the ozone generator 8. Control
The la 11 is equipped with a microcomputer, and the microcomputer has a timer function, a setting function, a control function,
It has a reservation function, a continuous operation function without reservation, and the like, and can set the operating time of the ozone generator 8 and the hot water temperature.
Then, the ozone generator 8 and the heater 6 are controlled as set by the control function. The controller 11 is
As shown in FIG. 3, it has a digital display section 12 and a numeric keypad 13 for setting the mode, and this numeric keypad 13 has a numerical key 14 of "0" to "9". It is composed of six setting keys "13a" to "13f" for setting the mode. The display unit 12 displays the set numerical value, hot water temperature, and time by switching. In addition, the display unit 12
A lighting lamp 15 for displaying the operating states of the pump 3, the heater 6, and the ozone generator 8 is provided below the.
The setting key "13a" is for issuing a control start signal of the controller 11, the key "13b" is for setting the repetition time of the ozone generator, and the key "13c" is for setting the setting time. "13d" is for setting the temperature of the hot water,
"e" indicates the time display signal of the display unit 12, and the key "1"
3f "emits setting signals for various modes. Therefore, for example, when setting the temperature of the bath water to 40 degrees Celsius, the key "13f", the key "13d", and the numerical key 14
"4", "0", key "13d" in that order. As a result, the hot water temperature is set to 40 degrees Celsius. When the start key "13a" is pressed, the microcomputer starts the operation according to the program and controls the heater 6 so that the hot water temperature becomes 40 degrees or is maintained.

Next, when the ozone generation time is set to, for example, 10 minutes, the key "13f", the key "13c",
Type "1", "0", and "13f" on the numeric keypad in this order. When the sterilization repetition time, that is, the ozone generation repetition time is set to, for example, 2 hours, the key "13
f ”, key“ 13b ”, numeric key 14“ 2 ”, key
Strike in the order of "13f". As a result, the ozone generator 8 has two
It is set to generate ozone for 10 minutes every hour. Since the microcomputer has a timer function and a control function, the ozone generator 8 is on / off controlled as set. It is obvious that the controller 11 can be implemented by a dial instead of the ten key.

[0019]

As described above, according to the present invention, the apparatus for filtering the bath water, the activation tank for purifying the bath water, the heating device for heating the bath water, and the ozone generator are provided. Therefore, when the circulation pump is driven, the bath water in the bath circulates between the filtration device, the activation tank, the heating device, etc., during which the filtration device causes a relatively large amount of dirt and human dust in the bath water. Hair etc. are removed. The activation tank is filled with one or more activated stones such as barley stone, sulfur stone, obsidian, rhyolite, and unweathered pearlite. As the ions are exchanged in the bath, minerals such as magnesium and zinc or active ingredients such as calcium and sodium are dissolved in the bath, and the bath has a hydrogen ion concentration adjusted from neutral to weak. This imparts a bathing effect to the bath water. In addition, the bacterium, which propagates on these activated stones and which nourishes, decomposes, for example, ammonia and organic substances that cause the bath to decompose, and the bath is purified.
