Description

[0001]
[Industrial applications]
The present invention relates to an apparatus for cleaning bath water, and more particularly to an apparatus for sterilizing bath water.
[0002]
[Prior art]
Hot water in bathtub is forcibly circulated using a circulating pump, and after removing dirt from the hot water with a filtration device installed in the circulation path, the bath water cleaning device is activated in an activated stone tank. Has been conventionally developed.
[0003]
More recently, in addition to simply removing or activating dirt in the hot water, it has been heated by a heater to always maintain an appropriate temperature so that the user can take a bath at any time of the day, 24 hours a day.
[0004]
In this case, it is needless to say that the hot water must always be kept clean, but sterilization is also required to prevent the generation of offensive odor.
[0005]
Conventionally, hot water has been sterilized by chlorine with chemicals, but recently a small high pressure discharge type ozone generator, so-called ozonizer, has been developed. As shown in FIG. 6, an ozonizer is used. Most of the devices are simple and easy to sterilize.
[0006]
In this apparatus, the hot water 2 in the bathtub 1 is sucked up by a circulation pump 6 from a hot water suction pipe 3 having a pre-filter 10 attached to the tip thereof to an apparatus main body 4 in which various cleaning processing devices are collectively stored. The hot water having been subjected to the cleaning treatment is ejected again into the bathtub 1 from a fountain pipe 9 having a jet nozzle 11 attached to the end thereof.
[0007]
The apparatus main body 4 is connected with a filtration tank 5 filled with various filter media such as activated carbon, barley stone, zeolite, etc., a circulation pump 6 for forcibly circulating hot water, a heater 7 for keeping the hot water at an appropriate temperature, and the like. One end of the hot water pipe 3 is connected to the inlet of the filtration tank 5 and one end of the hot water pipe 9 is connected to the outlet of the circulation pump 7 so that the hot water 2 in the bathtub 1 is connected. To form a cleaning circuit in series.
[0008]
A jet nozzle 11 attached to the end of the fountain pipe 9 is provided with an ejector section for taking in air using a negative pressure formed by increasing the flow rate of the hot water and mixing air into the hot water. An intake pipe 12 provided with an electromagnetic valve 13 at the mouth is connected, and an ozonizer 8 for ozonizing the sucked air is attached to the intake pipe 12.
[0009]
In the above apparatus, the hot water 2 in the bathtub 1 is sucked up from the water suction pipe 3 while being cleaned by the pre-filter 10 by the operation of the circulation pump 6 and enters the apparatus main body 4, and is first filtered in the filtration tank 5. Subsequently, after being kept warm by the heater 7, the jet is jetted into the bathtub 1 again from a jet nozzle attached to the tip of the hot water pipe 9.
[0010]
At this time, when the electromagnetic valve 13 provided at the intake port is open, air is sucked into the intake pipe 12, and a jet stream containing air is ejected from the jet nozzle 11 into the bathtub 1 to form a so-called bubble bath. Further, when the ozonizer 8 is operated, the sucked air is ozonized, and the hot water 2 in the bathtub 1 is ozone sterilized.
[0011]
[Problems to be solved by the invention]
However, as described above, when ozone is directly mixed into hot water circulating in the cleaning pipe to ozone-sterilize, it must be completely sterilized in a short reaction time in accordance with the circulation speed of the hot water. Ozone is mixed into the hot water.
[0012]
As a result, considerable unreacted ozone remains in the hot water, and when hot water containing such unreacted ozone is jetted into the bathtub, a large amount of ozone is released from the bathtub into the bathroom, Bathers not only get uncomfortable by smelling the peculiar ozone odor, but also worry about harm to their health if they inhale it.
[0013]
In order to prevent ozone from being released into the bathroom and causing harm to the bather, ozone is mixed into the hot water in a pipe upstream of the bathtub, and the ozone is not allowed to enter the bathtub before the hot water enters the bathtub. It is conceivable that the reaction ozone is separated by a gas-liquid separator, and the separated ozone is decomposed by a decomposer to make it harmless and then exhausted.
[0014]
However, if a gas-liquid separator is provided, the cleaning device itself becomes complicated and expensive, and the ozone separated from the hot water is humid and cannot be easily decomposed. Large and expensive decomposition equipment is required.
[0015]
The present invention solves the above-mentioned disadvantages of the prior art when ozone is directly mixed into hot water circulating in a cleaning pipeline and sterilized with ozone, and there is no fear of harm caused by unreacted ozone. It is an object of the present invention to provide a cleaning device having a simple and easy bathtub hot water sterilization and purification device.
[0016]
[Means for Solving the Problems]
The present invention provides a bathtub hot water purifying apparatus in which water in a bathtub is pumped up, the dirt is filtered by a filtering device, sterilized by a sterilizing device, heated to an appropriate temperature by a heater, and then ejected to the bathtub again. A main cleaning pipe line in which a hot water pipe, a filtration tank, a heater, a circulation pump, and a hot water pipe located at one end in a bathtub are connected in series, and a sterilizing hot water pipe and an ozonizer located at one end in a bathtub. An ozone sterilization tank to be connected, a circulation pump, and a sterilization pipeline in which one end is located in the bathtub and in which a sterilization fountain pipe is connected in series are provided, and in the main cleaning pipeline, a circulation pump for the main cleaning pipeline is provided. By operation, the hot water in the bathtub is pumped up from the suction pipe, the dirt is filtered by the filtration tank, heated to an appropriate temperature by the heater, and then discharged from the fountain pipe into the bathtub for continuous main cleaning treatment. In, circulation for sterilization pipeline The pump is operated to pump the hot water in the bathtub from the hot water suction pipe and store it in the ozone sterilization tank, then stop once, and in the ozone sterilization tank, mix the ozonized air into the stored hot water and sterilize it with ozone. After the ozone sterilization is completed, the circulation pump is operated and stopped again, and the sterilized hot water in the ozone sterilizing tank is jetted out of the sterilizing hot water pipe into the bathtub. The problem was solved by the ozone sterilization treatment of storing in a sterilization tank and then performing ozone sterilization repeatedly and separately from the main cleaning treatment.
Further, the present invention also provides a bathtub hot water purifier in which the hot water in the bathtub is pumped up, the dirt is filtered by a filtering device, sterilized by a sterilizing device, heated to an appropriate temperature by a heater, and then ejected to the bathtub again. A main cleaning pipe in which a water suction pipe, a filtration tank, a heater, a circulation pump, and a fountain pipe whose one end is located in the bathtub are connected in series. Continuous main cleaning process in which the water in the bathtub is pumped from the suction pipe by the operation of the circulation pump for the pipeline, the dirt is filtered by the filtration tank, heated to the appropriate temperature by the heater, and then discharged from the spray pipe into the bathtub. Is carried out, one end is located in the bathtub, and a sterilizing water suction pipe provided with an electromagnetic valve, an ozone sterilizing tank connected to an ozonizer, and an ejector part provided at one end to a fountain pipe of a main cleaning conduit. Sterilization fountain pipe connected to In the sterilization pipe line formed by connecting, the electromagnetic valve was opened and the hot water in the bathtub was pumped from the sterilization hot water pipe based on the suction force of the ejector part connected to one end of the sterilization water pipe and stored in the ozone sterilization tank. The rear end is closed, the ozonized air is mixed into the stored hot water in the ozone sterilization tank, and ozone sterilization is performed. After the ozone sterilization is completed, the solenoid valve is opened and closed again to discharge the sterilized hot water in the ozone sterilization tank. Ozone sterilization is the main purification process in which the water in the bath tub is squirted out of the sterilizing hot water pipe from the sterilizing hot water pipe through the hot water pipe in the main cleaning channel, pumped up again from the sterilizing hot water pipe, stored in the ozone sterilizing tank, and then sterilized with ozone. The problem was solved by being repeatedly executed separately from the processing.
[0017]
Effect of the Invention
The present invention is configured as described above, and since the sterilizing line is independent of the main cleaning line mainly for filtration, the sterilizing line is not affected by the processing speed of the hot water in the main cleaning line, and It can be sterilized by taking the necessary time depending on the condition.
[0018]
For this reason, even if the ozone sterilization method is adopted as the sterilization method, the sterilization can be performed with sufficient time by using the necessary minimum amount of ozone, so that the unreacted ozone can be effectively sterilized without remaining in the hot water.
[0019]
Also, when the germicidal fountain pipe of the germicidal pipe is connected to the main cleaning pipe, if the connection position is the suction side pipe of the circulating pump, the suction force of the circulating pump is used as it is, and the connection position is the discharge side pipe of the circulating pump. In the case of a passage, the circulation pump of the main cleaning line can be used without using a circulation pump in the sterilization line, using the suction force of the ejector section to reduce the diameter of the tube and increase the flow rate of hot water. And enough hot water can be circulated.
[0020]
【Example】
Next, an embodiment of the present invention will be described with reference to the drawings.
[0021]
FIG. 1 shows a first embodiment of the present invention. A main cleaning line 14 mainly for filtration is a line obtained by removing a sterilizing function from the conventional cleaning line, and is connected to a jet nozzle 11. This is a pipe line in which the ozonizer 8 has been removed from the intake pipe 12 to be removed.
[0022]
Reference numeral 15 denotes a sterilizing line completely independent of the main cleaning line 14. The sterilizing line 15 has a pre-filter 25 attached to a tip for pumping hot water 2 in the bathtub 1, and a sterilizing circulation pump 17 is provided on the way. A sterilizing hot water pipe 16, a sterilizing tank 18 for storing hot water for sterilization, and a sterilizing hot water pipe 19 for ejecting the hot water stored in the sterilizing tank 18 to the bathtub 1 again.
[0023]
The sterilization tank 18 of this embodiment is configured as an ozone sterilization tank for performing ozone sterilization using ozonized air generated by the ozonizer 8, as in the above-described conventional example.
[0024]
Therefore, at the bottom of the sterilizing tank 18, a diffuser plate 20 for uniformly jetting the ozonized air into the tank is provided. The diffuser plate 20 has an air pump 22 at the tip thereof, followed by the ozonizer 8 and the electromagnetic pump. An air supply pipe 21 provided with a valve 23 is connected thereto, and an exhaust valve 24 is mounted on the upper surface of the tank.
[0025]
Therefore, in the apparatus of the present embodiment, the hot water 2 in the bathtub 1 is first drawn up by the operation of the circulation pump 6 while filtering large dirt from the suction pipe 3 with the pre-filter 10, and is filtered in the filtration tank 5. After the heater 7 keeps the temperature at an appropriate temperature, the water is circulated through the main cleaning pipe 14 mainly for filtration, which is jetted again from the fountain pipe 9 into the bathtub 1.
[0026]
In the circulation of the main cleaning pipe 14, a jet nozzle 11 connected to the suction pipe 12 at the negative pressure portion is attached to the tip of the fountain pipe 9, so that the jet nozzle 11 is opened by opening the solenoid valve 13 and sucking air from the suction pipe 12. A jet stream containing air is blown out from the air to form a bubble bath.
[0027]
The hot water 2 in the bathtub 1 is separated from the main cleaning line 14 by the operation of the circulating pump 6, while the sterilizing and circulating pump 17 is operated to remove large dirt by the pre-filter 25 by the sterilizing and suction pipe 16 by the operation of the sterilizing circulating pump 17. It is pumped up and circulated through the sterilizing line 15 as follows to be sterilized.
[0028]
That is, the germicidal circulation pump 17 is first activated for a time sufficient for the hot water 2 in the bathtub 1 to be stored in the sterilizing tank 18 to a predetermined water level, and automatically stopped when the hot water is stored in the sterilizing tank 18 to the predetermined water level.
[0029]
If hot water is stored in the sterilization tank 18 to a predetermined water level and the sterilization circulation pump 17 stops, instead of opening the solenoid valve 23, the air pump 22 and the ozonizer 8 are operated, and the ozonized air is diffused from the air supply pipe 21. It is jetted into the hot water stored from the plate 20 to sterilize it.
[0030]
When the sterilization for a predetermined time is completed, the operation of the air pump 22 and the ozonizer 8 is stopped at the same time as closing the electromagnetic valve 23, the exhaust valve 24 is opened, and the inside of the sterilization tank 18 is exhausted for a predetermined time.
[0031]
When the evacuation of the sterilizing tank 18 is completed, the exhaust pump 24 is closed, and at the same time, the circulation pump 17 is operated again for a predetermined time, and the sterilized hot water in the sterilizing tank 18 is spouted out of the sterilizing fountain pipe 19 into the bathtub 1. Pump hot water 2 for the next sterilization from bathtub 1.
[0032]
The hot water 2 in the bathtub 1 circulates through the sterilizing line 15 while repeating the above operation, and is sterilized by the batching process irrespective of the continuous cleaning process mainly including the filtration in the main cleaning line 14. It is processed.
[0033]
Therefore, if the amount of ozonized air used for the sterilization treatment and the treatment time are carefully examined in advance in experiments, complete sterilization can be performed with almost no unreacted ozone left in the hot water, so that the water was ejected into the bathtub. Since ozone is not released from hot water or air exhausted from the sterilizing tank, even if the sterilizing process is performed during bathing, no harm is caused to the bather.
[0034]
In addition, the amount of ozonized air to be mixed in and the treatment time can be freely adjusted, so if these conditions are adjusted automatically or manually according to the degree of contamination of the hot water, the sterilization treatment of the hot water can be performed under necessary and sufficient conditions constantly. become able to.
[0035]
Next, a second embodiment will be described with reference to FIG.
[0036]
The basic configuration of this embodiment is the same as that of the first embodiment, and an ejector section 26 for reducing the diameter of the fountain pipe 9 of the main cleaning pipe 14 to increase the flow velocity of the hot water and to generate a negative pressure is provided. The distal end of the sterilizing jet pipe 19 of the sterilizing pipe 15 is connected to the ejector section 26.
[0037]
In this embodiment, since the circulation of the hot water 2 in the bathtub 1 to the sterilization conduit 15 is performed by the suction force of the ejector unit 26, the sterilization circulation pump 15 is provided with the sterilization circulation pump 17 as in the first embodiment. There is no need to provide it. Instead, the sterilizing water suction pipe 16 is provided with an electromagnetic valve 27 for opening and closing the water suction passage.
[0038]
Further, in the first embodiment, the supply of the ozonized air from the air supply pipe 21 to the sterilization tank 18 is performed by using the pressing force of the air pump 22, but in the present embodiment, the suction force of the ejector unit 26 is used. Since it is possible, there is no problem even if the air pump 22 is omitted.
[0039]
Therefore, in this embodiment, if the electromagnetic valve 27 is opened for a predetermined time while hot water is circulating in the main cleaning pipe 14, the hot water 2 in the bathtub 1 is stored in the sterilization tank 18 to a predetermined water level, and the electromagnetic valve 23 is opened. Sterilization for a predetermined time can be performed by mixing ozonized air.
[0040]
Next, a third embodiment will be described with reference to FIG.
[0041]
In the present embodiment, the jet nozzle 11 provided at the end of the jet nozzle 9 of the jet pipe 9 of the main cleaning pipe 14 also serves as the jet nozzle. Therefore, the tip of the sterilizing jet pipe 19 of the sterilizing pipe 15 is connected to the ejector section of the jet nozzle. are doing.
[0042]
Therefore, in the present embodiment, as shown in FIG. 4, the electromagnetic valve 27 of the sterilizing water suction pipe 16 is closed, the hot water is not stored in the sterilizing tank 18, and the electromagnetic control of the air supply pipe 21 is performed without operating the ozonizer 8. If the valve 23 is opened, a jet stream containing air is ejected from the jet nozzle 11 at the tip of the fountain pipe 9 to form a bubble bath.
[0043]
Next, a fourth embodiment will be described with reference to FIG.
[0044]
This embodiment is different from the second and third embodiments in that the germicidal fountain pipe 16 of the germicidal pipe 15 is connected to the fountain pipe 9 on the discharge side of the circulation pump 6 of the main cleaning pipe 14. , Is connected to the suction pipe 3 on the suction side via a switching valve 28.
[0045]
For this reason, the circulation of the hot water 2 in the bathtub 1 to the sterilization conduit 15 can be performed by using the suction force of the circulation pump 6 of the main cleaning conduit 14, and as in the second and third embodiments, There is no need to connect the germicidal fountain pipe 19 of the germicidal conduit 15 to the main cleaning conduit 14 via an emitter.
[0046]
Therefore, in this embodiment, if the switching valve 28 of the hot water pipe 3 of the main cleaning pipe 14 is switched so as to communicate with the direction of the sterilizing water pipe 19 of the sterilizing pipe 15 only for a predetermined time, the inside of the bathtub 1 is changed. The hot water 2 is circulated through the main cleaning pipe 14 and at the same time is pumped up to a predetermined water level in the sterilization tank 18 to be sterilized.
[0047]
As shown in the above-described second to fourth embodiments, the sterilizing conduit 15 can be connected to the sterilizing fountain pipe 19 at any position of the main cleaning conduit 14 without any special circulation pump. A predetermined amount of hot water 2 in 1 is stored in a sterilization tank 18 and sterilization can be performed.
[0048]
【The invention's effect】
The present invention has the above-described structure and operation. Since a sterilizing line provided with a sterilizing tank is provided independently of the main cleaning line mainly for filtration, sterilization is performed by the main cleaning. It can be performed as a batching process irrespective of the cleaning in the pipeline.
[0049]
As a result, even if ozone sterilization in which release of unreacted ozone is a problem is performed, sterilization can be performed with a minimum amount of ozone for a sufficient time, and as a result, complete unreacted ozone is hardly left in the hot water. Sterilization can be performed, and there is no need to worry about the release of ozone into the bathroom. Therefore, even if sterilization is performed during bathing, there is no harm to the bather.
[0050]
Also, the configuration of the apparatus can be made extremely inexpensive and simple by connecting the sterilizing fountain pipe of the sterilizing pipe to the main cleaning pipe without the necessity of providing a special circulation pump in the sterilizing pipe.
[0051]
In this device, the sterilization time can be easily changed by controlling the operation time of the sterilization circulation pump or the opening / closing time of the valve provided in the pipeline, so that the ozonized air can be manually or automatically operated depending on the degree of contamination of the hot water. The sterilization treatment time is controlled together with the amount of the mixed water, and the complete sterilization treatment can be performed without leaving unreacted ozone as described above.
