Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath water cleaning device, and more particularly to a sterilization device for this device.

[0002]

2. Description of the Related Art Bath water forcibly circulated in a bathtub by using a circulation pump to remove dirt from the hot water by a filtration device provided in a circulation path and then activated in an activated stone tank The purifying device has been conventionally developed.

More recently, in addition to simply removing dirt and activating it in hot water, it is heated by a heater to always maintain an appropriate temperature so that the user can take a bath at any time for 24 hours.

In this case, it is needless to say that the hot water must be kept clean, but sterilization is also necessary in order to prevent the generation of a bad odor.

In the past, sterilization of hot water was conventionally performed by chlorine sterilization with chemicals, but recently, a small high-pressure discharge type ozone generator, so-called ozonizer, was developed.
As shown in FIG. 6, most devices use an ozonizer for easy sterilization.

In this apparatus, the hot water 2 in the bathtub 1 is sucked up by a circulating pump 6 from a hot water pipe 3 having a prefilter 10 attached to the tip thereof to a main body 4 of the apparatus in which various cleaning treatment devices are collectively housed. The cleaning process is performed, and the hot water after the cleaning process is ejected again into the bathtub 1 from the spout tube 9 having the jet nozzle 11 attached to the tip thereof.

The apparatus body 4 is provided with a filtration tank 5 filled with various types of granular filter media such as activated carbon, barley stone, zeolite, a circulation pump 6 for forcedly circulating hot water, and a heater 7 for keeping the hot water at an appropriate temperature. Etc. are connected and connected in series by a connecting pipe, and one end of the hot water suction pipe 3 is connected to the hot water inlet of the filtration tank 5.
One end of the spout tube 9 is connected to the discharge port of the circulation pump 7 to form a series cleaning circulation path for the hot water 2 in the bath 1.

The jet nozzle 11 attached to the tip of the spout tube 9 is provided with an ejector portion for inhaling air by using a negative pressure formed by accelerating the flow velocity of the hot water to mix air into the hot water. An intake pipe 12 having a solenoid valve 13 at its intake port is connected to the intake pipe 12, and an ozonizer 8 for ozone-izing the sucked air is attached to the intake pipe 12.

In the above apparatus, the hot water 2 in the bathtub 1 is sucked up from the hot water pipe 3 while the dirt is removed by the prefilter 10 by the operation of the circulation pump 6 and the apparatus main body 4
First, it is filtered in the filtration tank 5, and then the heater 7
After being kept warm by, it is jetted again into the bathtub 1 from the jet nozzle attached to the tip of the spout tube 9.

At this time, air is sucked into the intake pipe 12 when the solenoid valve 13 provided at the intake port is open, and a jet flow mixed with air is jetted from the jet nozzle 11 into the bathtub 1.
It becomes a so-called bubble bath that is jetted into the interior, and when the ozonizer 8 is operating, the air that is drawn in is ozoned,
The hot water 2 in the bathtub 1 is sterilized by ozone.

[0011]

However, as described above, when ozone is sterilized by directly mixing ozone into the hot water circulating in the cleaning pipe, the reaction is completed with a short reaction time according to the circulation rate of the hot water. Since it must be sterilized, excess ozone is inevitably mixed in the hot water.

As a result, a large amount of unreacted ozone remains in the hot water, and when hot water containing unreacted ozone is jetted out into the bathtub, a large amount of ozone is discharged from the bathtub into the bathroom. As a result, the bather not only feels unpleasant by smelling the unique ozone odor, but is also anxious about the health hazard if inhaled.

In order to prevent ozone from being released into the bathroom and damaging the bather in this manner, ozone is mixed into the hot water in a pipe line upstream of the bathtub, and hot water is added before the hot water enters the bathtub. It is considered that unreacted ozone is separated from the inside by a gas-liquid separator, the separated ozone is decomposed by a decomposer to make it harmless, and then exhausted.

However, when the gas-liquid separation device is provided, the main body of the cleaning device becomes complicated and expensive, and the ozone separated from the hot water cannot be easily decomposed because it is moist, and the decomposition is completed. Requires a fairly large and expensive cracker.

The present invention solves the above-mentioned drawbacks of the prior art when ozone is sterilized by mixing ozone directly in hot water circulating through a cleaning pipeline, and the harm of unreacted ozone is eliminated. It is an object of the present invention to provide a cleaning device which has no fear and is simple and has a bath water sterilizing device.

[0016]

That is, the present invention is a bathtub hot water purifying device for cleaning hot water in a bathtub by forcibly circulating the hot water in a bathtub through a circulation path provided with various cleaning devices. In, independent of the main cleaning pipe which mainly sucks the hot water in the bathtub from the hot water pipe and filters it by the filter device, further heats it with a heater and then jets it again from the hot water pipe into the bathtub, A bathtub hot water purifying device characterized by having a sterilization pipe line for sucking hot water in a bathtub from a sterilization hot water pipe, storing it in a sterilization tank and sterilizing it and then ejecting it from the sterilization hot water pipe into the bathtub, Also, the sterilization pipeline is a device for cleaning bathtub hot water, characterized in that it is connected to a main cleaning pipeline through a sterilization spray pipe that sprays hot water after sterilization, and the sterilization tank further comprises a sterilization suction pipe. The hot water that was sucked up from the hot water pipe and stored A cleaning device of the bath water, characterized in that produced by the ozonized air ejected from the air diffuser plate is ozone sterilization tank to a predetermined time ozone sterilized Naiza.

[0017]

The present invention is constructed as described above, and since the sterilization pipeline is independent of the main purification pipeline mainly composed of filtration, it is not affected by the hot water treatment rate of the main purification pipeline. ,
It can be sterilized by taking the necessary time depending on how dirty the hot water is.

Therefore, even if the ozone sterilization method is adopted as the sterilization method, it is possible to sterilize for a sufficient time by using the minimum required amount of ozone, so that unreacted ozone can be effectively sterilized without being left in the hot water. become.

When the sterilization spout tube of the sterilization pipeline is connected to the main cleaning pipeline, if the connection position is the suction side pipeline of the circulation pump, the suction force of the circulation pump is used as it is, and the connection position is the circulation pump. In the case of the discharge side pipe, the suction force of the edger part that narrows the pipe diameter to speed up the flow rate of hot water is used to circulate the main purification line without installing a circulation pump in the sterilization line. The hot water can be circulated by the action of the pump.

[0020]

Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 shows a first embodiment of the present invention,

Therefore, in the apparatus of this embodiment, the hot water 2 in the bathtub 1 is first pumped by the operation of the circulation pump 6 while filtering large dirt from the hot water pipe 3 by the prefilter 10 and then in the filtration tank 5. After being filtered and kept at an appropriate temperature by the heater 7, it is circulated through the main cleaning pipe line 14 mainly composed of the filter which is again jetted from the spout pipe 9 into the bath 1.

In the circulation of the main cleaning pipe line 14, since the jet nozzle 11 to which the intake pipe 12 is connected to the negative pressure portion is attached to the tip of the spout pipe 9, the solenoid valve 13 is opened to intake air from the intake pipe 12. As a result, a jet flow containing air is ejected from the jet nozzle 11 to form a bubble bath.

The hot water 2 in the bathtub 1 is the circulating pump 6 described above.

That is, the sterilization circulation pump 17 is first operated for a time such that the hot water 2 in the bathtub 1 is stored in the sterilization tank 18 up to a predetermined water level, and automatically when the hot water is stored in the sterilization tank 18 up to the predetermined water level. Stop.

If hot water is stored in the sterilization tank 18 to a predetermined water level and the sterilization circulation pump 17 is stopped, the solenoid valve 23 is opened at the same time, the air pump 22 and the ozonizer 8 are operated at the same time, and the ozonized air is supplied from the air supply pipe 21. The air diffuser 2
It sterilizes by spraying from 0 in hot water.

When the sterilization for a predetermined time is completed, the solenoid valve 23
At the same time, the operation of the air pump 22 and the ozonizer 8 is stopped and the exhaust valve 24 is opened to exhaust the inside of the sterilization tank 18 for a predetermined time.

When the exhaust of the sterilization tank 18 is completed, the exhaust valve 24 is closed and the circulation pump 17 is operated again for a predetermined time, and the sterilized hot water in the sterilization tank 18 is ejected from the sterilization spout pipe 19 into the bath 1. At the same time, the hot water 2 for the next sterilization is pumped up from the bath 1.

While repeating the above operation, the bathtub 1
The hot water 2 in the inside circulates through the sterilization pipe line 15, and is sterilized by the batch process regardless of the continuous cleaning process mainly consisting of filtration in the main cleaning pipe line 14.

Therefore, if the amount of ozonized air to be used for sterilization treatment and the treatment time are carefully examined in advance by experiments, complete sterilization can be performed with almost no unreacted ozone left in the hot water. Ozone is not released from the hot water that is ejected or the air that is exhausted from the sterilization tank.
Even if sterilization is performed during bathing, it does not harm the bather.

Further, since the amount of ozonized air to be mixed and the treatment time can be freely adjusted, if these conditions are adjusted automatically or manually according to the degree of contamination of the hot water, the hot water is constantly required and sufficient. Be able to sterilize.

Next, a second embodiment will be described with reference to FIG.
