Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method and apparatus for purifying hot water in a bathtub, and more particularly, to an improvement in technology for injecting and mixing ozone into circulating hot water in a bathtub. .

[Prior Art] As is well known, as lifestyles have become more sophisticated and diversified, a wide variety of improvements have been made to bathing, such as purifying hot water in bathtubs, deodorizing hot water, and Means for sterilizing and sterilizing fungi that are unsuitable for maintaining physical health in warm water are in practical use. That is, it is usually referred to as a bathtub hot water purification or cleansing means, or a deodorizing and sterilizing means, and this device includes at least a filtration means.
A hot water inflow pipe system for causing hot water in the bathtub to flow into the filtration device for performing the final stage filtration action of the two-leg filtration means, and 1- hot water for circulating hot water from the filtration device into the bathtub. It has an outflow pipe system and a circulation pump, and also has an ozone mixer for injecting and mixing ozone generated by the ozone generator into the hot water circulation system. In the above, the filtration means is not only singular, but also may be arranged in multiple stages such as -order, secondary, etc. In addition, there are cases where the filtration means is arranged in multiple stages such as -order, secondary, etc.; There are various types, including activated stones (such as activated stones) and ceramics.In addition, a far-infrared ceramic heater is placed in the bipedal circulation system to keep the circulating hot water at a constant temperature, for example around 42℃. Some did.

By the way, if we look at the specific conventional technology of this hot water circulation purification device, we can see that in the past, ozone generated by an ozone generator was injected,
An ozone mixer for mixing is arranged in an outflow pipe system extending from the secondary side of the filtration device and connected to the outflow end of the bathtub, particularly in an outflow pipe system located close to the outflow end of the bathtub.

[Problems to be Solved by the Invention] The above-mentioned prior art is capable of removing dirt, oil, etc. mixed into bathtub hot water by its performance when focusing on a filter using one or more of the filtration devices themselves. When using filters, activated stones, ceramics, etc. as filtration media to purify hot water, they exhibit several excellent advantages such as their filtration function and mineralization of water quality. When considering the injecting and mixing of ozone into hot water, several problems are found. I
! There are several and multifaceted reasons for injecting and mixing ozone into hot bath water, but some of them are as follows. One is that it deodorizes odors in hot water. More specifically, the ozone odor may be used to mask odor, but in particular, it oxidizes and removes dissolved malodorous components. Furthermore, activated carbon or the like is more preferable than the material 2 in the filtration device, which promotes the reaction between ozone and malodorous components to oxidize and remove odors.

The second is the sterilization and sterilization of harmful bacteria in warm water due to the sterilizing effect of ozone itself. Part 3 is to inject and mix ozone into hot water to activate the action of microorganisms in the warm water, and more specifically, to activate the action of aerobic microorganisms with nitrogen components, and more specifically to the filtration equipment. These include activating aerobic microorganisms that breed in the water and decomposing and removing organic matter. However, in the past, the ozone mixer was placed at the outflow end of the bathtub, and most of the time, the ozone mixer was placed at the outflow end of the bathtub, and the ozone mixer was generally used for the hot water in the bathtub, that is, for the filtration device.
3. Ozone is injected and mixed into the hot water coming out of the filtration device, not into the hot water that is about to flow in.
Although ozone itself has the functions of deodorizing, sterilizing, and decomposing organic matter, it flows out in the form of bubbles from the hot water surface of the bathtub before being circulated to the filtration device. The deodorizing effect of ozone that accompanies the reaction promotion is hardly used, resulting in low deodorizing efficiency.Also, aerobic microorganisms breed in large numbers in the filtration device, and for the same reason, ozone activates the aerobic microorganisms. The efficiency of organic matter decomposition is low.

That is, there is no correlation between ozone injection and the function of the filtration device.

In particular, the following points are major problems.

That is, although ozone itself is effective, it is also toxic to the human body. If the amount dissolved is not appropriate, that is, if it is in excess, it may cause irritation, remain toxic to the human body, and sometimes lead to death. Therefore, it is necessary to inject and mix ozone into warm water at a predetermined appropriate concentration that will bring out the effective function of ozone and will not cause any harm to the human body, but in reality, it is extremely difficult to set this. Therefore, if it is injected and mixed at the outflow end of the bathtub as in the prior art, excess ozone may come into direct contact with the human body, and I! Health-L is unfavorable.

[Object] Accordingly, an object of the present invention is to provide a bathtub hot water circulation method and its device that can correlate ozone injection with the function of a filtration device. Specifically, by injecting and mixing ozone upstream of the final stage of filtration, the material used in the filtration means promotes the reaction between ozone and malodorous components, thereby increasing deodorizing efficiency and removing excess ozone. The purpose is to remove the organic matter by adsorption using a filter material, or to further promote the activation of aerobic microorganisms that proliferate in the filter material, thereby making it possible to decompose and remove more organic matter.

In addition, the objective is to eliminate as much as possible the negative effects on the human body without injecting or mixing ozone excessively. Moreover, the present invention has the following technical considerations in order to achieve the above object. . That is, to explain this using the reference numerals in the accompanying drawings corresponding to the embodiments, the method of the present invention inhales hot water from a bathtub,
Next, the hot water is purified or purified, activated, and kept at a constant temperature by filtration, filtration, hot water activation, and thermal insulation heating, and then flowing out to the bathtub side. In the bathtub hot water purification and circulation method in which ozone is injected into the hot water in the process, the ozone is injected into the circulating hot water at a position where the final stage of filtration is applied, and at the same time, '' A bathtub hot water purification method characterized by the ability to separate air generated in hot water at a position downstream from the ozone injection position, and the device invention comprises at least a filtration means and the above-mentioned filtration means. A hot water inflow pipe system 6 for injecting the hot water W in the bathtub 1 into the filtration device 3 for carrying out the final stage filtration action, and a hot water inflow pipe system 6 for causing the hot water W to flow out from the filtration device 3 into the bathtub 1. In a bathtub hot water purification and circulation device which has a hot water circulation system consisting of a hot water outflow pipe system 12 and a circulation pump 9, and also has an ozone mixer for injecting ozone generated by an ozone generator 14 into the hot water circulation system. ; An ozone mixer connected to the ozone generator 14 via an ozone injection pipe 15! 6 is disposed in the hot water inflow pipe system 6 corresponding to the primary side with respect to the position of the final stage filtration device 3, and a gas-liquid separator 17 is installed downstream of the ozone mixer 16. This is a bathtub warm water purifying circulation device that is characterized by the following:

[Function] With the above configuration, hot water in the bathtub 1 flows into the filtration device 3 via the hot water inflow pipe 6 by the circulation pump 9. It is filtered there. In this case, in addition to simply separating dirt and oil,
Filtering is performed using functions depending on the type of filter media. In addition, the filter medium itself also performs a deodorizing effect.
It flows out into the bathtub through the temperature. That is, the hot water is purified by circulation.

During this circulation process, ozone is injected and mixed from the ozone mixer 1G. Deodorization is achieved through masking or oxidation by the dissolved ozone itself, and harmful bacteria in the warm water are sterilized through sterilization. In addition, the growth of aerobic microorganisms is activated, and organic matter is decomposed and removed. etc.

However, the characteristic effects of the present invention are as follows.

Ozone is injected before the final stage filtration device 3.

Therefore, the function of promoting the reaction between ozone and malodorous components by the filter medium of the filter device 3 is likely to be facilitated, and in addition, aerobic microorganisms breed near the filter medium, making it easy to activate these aerobic microorganisms and decomposing and removing organic matter efficiently. <Implemented.

In particular, even if the ozone injection from the ozone mixer 16 is slightly excessive, it will not be possible to enter the bath where the human body is located.
The excess amount that is not dissolved in the gas-liquid separator 17 is discharged to the atmosphere.

Therefore, it is easy to set the optimal ozone injection amount [Example] Next, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the figure, 1 indicates a bathtub, and 2 indicates a hot water purifying circulation device.

A filtration means is disposed within the hot water purifying circulation device 2. In this example, it is shown as filtration device 3, which is located at the final stage. In this example, the filter device 3 includes a heater 3A, for example, a far-infrared ceramic heater, on the downstream side, and a filter stone 3B on the upstream side.

As the filter stone 3B, an appropriate material such as activated carbon, activated stone such as biostein, ceramics, etc. is selected.9 Next, a hot water inflow pipe 6 is connected between the lower part 4 of the bathtub 1 and the inflow end 5 of the filtration device 3. are connected to the hot water inflow pipe 6, and a valve 7, a hair catcher 8 as a filtering means (filtering device) are connected to the hot water inlet pipe 6 in order from upstream. A hot water circulation pump 9 is provided.

On the other hand, the F side portion 10 of the bathtub l and the outflow end 11 of the filtration device 3
A hot water outflow pipe 12 is connected between the hot water outflow pipe 12 and
A valve 13 is attached in the middle.

The following is an example of a conventional general hot water purifying circulation device, but the present invention is made as follows in order to achieve the above-mentioned object.

First, when focusing on the filtration device 3 located at the final stage of the above-mentioned filtration means, the hot water inflow pipe 6 located on the primary side thereof.
Place the ozone mixer 1B at the location.

The ozone mixer 16 may be of an orifice type or a counterflow discharge type. An example of the orifice type is shown in FIG. 2, and an example of the counterflow discharge type is shown in FIG. 4, and their actions will be described in the section of operation described below.

The means for sending ozone to the ozone mixer 16 uses a known ozone generator 14, which is composed of an ozone generation source 14A and an air pump 14B for feeding.
A and an ozone mixer 18 are connected by an ozone injection pipe 15.

The second improvement is to install a gas-liquid separator 17 at a position upstream of the ozone mixer 16, and in this example, it is installed at the top of the filtration device 3. . In addition to the float type shown in FIG. 3, the gas-liquid separator 17 may be of a solenoid valve type such as timer control or sensor detection control.

The operation will be explained based on the configuration described below.

As the circulation pump 9 is driven, the hot water W in the bathtub 1 flows in through the hot water inflow pipe 6, hair etc. are removed by the hair catcher 8, and then enters the filtration device 3 where it is heated by the heater 3A. The heater 3A is set to be turned off at a predetermined temperature, for example, 42° C. or higher, and turned on at a temperature lower than that, to keep the hot water warm. The hot water enters the filter medium 3B, where dirt and oil are separated or adsorbed or the pH is adjusted. The hot water W then returns to the bathtub l via the hot water outflow pipe 12 again.

In this way, it is cleaned by the filtration means.

In the above process, ozone is injected into the hot water W from the ozone mixer 16 and mixed.

Therefore, the masking effect of ozone masks the malodorous components of hot water, and the malodorous components caused by its oxidizing action are decomposed. Alternatively, it is sterilized or sterilized by the bactericidal action of ozone.

In addition, dissolved syn causes activation of aerobic microorganisms, which decomposes and removes organic matter.

By the way, ozone is injected and mixed before the filtration device 3.

Therefore, the user directly benefits from the promotion of the reaction between malodorous components and ozone by the filter medium in the filtration device 3, and can achieve better deodorization.

In addition, since there are many aerobic microorganisms in the filter media, they are more activated by dissolved syn, and the decomposition of organic matter is further promoted.

In particular, when injecting and mixing ozone, it is difficult to set the optimum concentration, but even if excess ozone is injected, it will be released into the atmosphere by the gas-liquid component #rl, 17 in the last stream of the filtration device 3. Since it can be separated as a gas, it is possible to prevent excess ozone from flowing back into the bathtub and causing toxicity to the human body.

In addition, air locks caused by excess ozone are also prevented.

The gas-liquid separation operation in this example is performed by lowering the float 25 as shown in FIG.
6 is carried out with the air outlet 27 open.

In addition, 23 is a casing, and 24 is a float sliding support.

Further, the operation of the orifice type ozone mixer 18 of this example will be described in detail. An orifice 20 is formed between the inflow side 18 and the outflow side 18, and the ozone injection pipe end 22 is connected to the expansion part 21. Pressure P from the inlet side 18 direction of diameter D2-
When water is fed at O, the pressure loss P2- due to the orifice part 20 with diameter d2-, the negative pressure PL generated in the expansion part 21 with diameter D2, and the pressure P2 at the outflow side 19 with diameter DA are expressed by the following formula. .

Pa = P2-+ (-Pi) + P2 This expansion part 21
The negative pressure pL at
This is caused by the Karman vortex associated with , but by appropriately setting D,>n2>DL>d2->dL, the pressure at the ozone inlet pipe end 22 becomes lower than atmospheric pressure.

That is, when a jet is generated by the orifice part 20 and negative pressure is generated in the expansion part 21, and ozone is sucked from the ozone injection pipe end 22, ozone and hot water are mixed in the path leading to the outflow side 19, and the apparent specific gravity is reduced. It becomes lighter. Therefore, the flow path loss at the expansion part 21 and the outflow side 19 is reduced, the negative pressure in the expansion part 21 is further increased, and more deactivated ozone is sucked in.

Furthermore, when using the counterflow discharge type shown in FIG.
The injection chamber 30 is formed, and the nozzle 3
1 to face each other. The ozone injection pipe 15 is connected to the chamber 3
Connected to 0. According to this, nozzle 31 for hot water
Ozone is discharged from the opposite side and mixed with the hot water.

Of course, the present invention is not limited to these examples of ozone mixer 16.

[Effects of the Invention] As detailed above, according to the present invention, since ozone is injected into hot water and mixed on the primary side of the final stage filtration device, the function of promoting the reaction between ozone and malodorous components is enhanced. The function of the vine material can be further promoted and deodorization can be achieved better.Since many aerobic microorganisms exist in the filtration device, the aerobic microorganisms near the filter material can be further activated and organic matter can be removed more effectively. 9, etc., which can be decomposed and removed, organically correlates ozone injection and filtration function.

In particular, it is difficult to inject ozone into hot water and properly set the mixing concentration, but even if you inadvertently inject too much ozone, it will separate before reaching the upstream side of the ozone mixer 16, that is, the bathtub l. Therefore, toxic effects on the human body can be eliminated as much as possible. In addition, it has various practical advantages, such as preventing air locks and preventing hot water circulation. More specifically, in order to forcibly mix ozone directly before the final filtration method, instead of injecting ozone directly into the hot bath water,
It is possible to utilize the sterilization and purification effect of ozone more effectively and safely for the human body.
