CONSTITUTION:An ozone water purifier 10 is equipped with an upper wall concave part 52, wherein a couple of electrodes 63 are arranged and also a water guide 51 is installed, in an ozone water discharge line 47 nearby an upper corner of a bent part 50 toward an outlet port 48, so that the ozone water flowing through the ozone water discharge line 47 collides with the water guide 51, changes its direction slantingly upward and is brought into contact with the couple of electrodes 63. When a tap water is supplied through a water inlet port 62, the ozone water remaining in a mixing chamber 43 flows into the ozone discharge line 47 at once, comes into contact with the couple of electrodes 63 to make them conduct electricity, and an electric power is automatically supplied to an ozone generation part 28 through a wiring 64 from a power source 24 so as to start an ozone generation.

Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to an ozone water purifier that mixes ozone into tap water, etc. and purifies the water with ozone, and particularly relates to a switch mechanism for generating the ozone. It is related to.

(Prior Art) Various water purifiers that purify tap water or the like immediately before use have been proposed. Such water purifiers use activated carbon or hollow fibers as filter media to remove organic matter, germs, and other microorganisms.

Water purifiers that use activated carbon pass tap water, etc. into a container filled with granular activated carbon, and when the tap water comes into contact with the activated carbon, impurities are removed by the activated carbon's adsorption power and filtration action.

On the other hand, water purifiers using hollow fibers filter water through a polymer membrane with extremely fine holes on a molecular level to separate and remove impurities.

By the way, water purifiers that use activated carbon or hollow fibers as filter media as mentioned above do not have basic sterilization ability, and bacteria can grow in the water stagnant inside the water purifier or on the filter media, and depending on the type of bacteria. However, there are problems such as hydrogen sulfide and other gases being emitted, which can give off odors.

In addition, methods that sterilize by irradiating ultraviolet rays and purifying water by electrolysis have been proposed, but the amount of irradiated ultraviolet rays may be reduced if the container becomes dirty.
There were problems such as not being able to obtain sufficient sterilizing ability, and it was not satisfactory.

In view of the problems of the various water purifiers mentioned above, an ozone water purifier has been provided which purifies water by mixing and dissolving ozone into water. This ozone water purifier sends a high-voltage, high-frequency current generated by a power supply circuit to an ozone generator, causing creeping discharge in the ozone generator to generate ozone, which is mixed and dissolved in water.

By the way, the ozone generation mechanism in the conventional ozone water purifier as described above can be activated and stopped by manually turning on the switch provided on the housing of the ozone water purifier. OFF
The structure was such that

(Problem to be Solved by the Invention) In such a manually operated structure, the ON/OFF switch must be turned on each time it is used. The OFF operation is complicated, and the ON or OFF operation is often forgotten.

If you forget to turn on the switch when water flows into the ozone cleaner, the ozone generation mechanism will not operate, and of course no ozone will be generated, so no water purification will be performed.

On the other hand, if you forget to turn off the switch when the water flow is stopped, the ozone generation mechanism will remain in operation even after the water flow has stopped, and ozone will continue to be generated. The ozone generating section, which is the heart of the ozone generating mechanism, has a predetermined lifespan, and it is undesirable for the ozone generating section to continue to generate ozone even in this unused state.

Therefore, installation of a warning buzzer has been proposed as a countermeasure against forgetting to turn on and off the switch, but this cannot be said to be a sufficient measure due to cost and other considerations.

SUMMARY OF THE INVENTION An object of the present invention is to provide an ozone water purifier that eliminates the various problems described above caused by the complexity of turning on and off the switch and forgetting to operate the switch.

(Means for Solving the Problems) The present invention utilizes a pair of electrodes that conduct through contact with water or ozonated water as the sinch mechanism of an ozone water purifier, thereby achieving an automatic switch for ozone generation. This solved the problem mentioned above.

The first invention of the present invention has an ozone generating part and a pair of electrodes that are electrically connected by contact with water or ozonated water, and automatically generates ozone when water is passed through it, thereby purifying water with ozone. It is characterized by

The second invention includes an ozone generator and a pair of electrodes that are disposed near the upper corner of the bent part of the ozonated water discharge channel toward the outlet, and that are electrically connected by contact with water or ozonated water. It is located at the lower corner of the bent part and has a water guiding part with a structure that protrudes diagonally upward, and when water flows through it, it automatically generates ozone and purifies water using ozo. shall be.

(Function) When the ozone water purifier of the present invention is used, there is no conduction between the pair of electrodes incorporated in the ozone water purifier, and the electric circuit is open. When water comes into contact with the electrodes, the water creates conduction between the pair of electrodes, closing the electrical circuit and activating the ozone generator of the ozone water purifier.

Furthermore, the so-called water guiding part provided at the lower corner of the bent part from the ozonated water discharge channel toward the outlet, which is preferable as the placement position of the electrode of the present invention, is particularly suitable for the electrode on the upper inner wall convex part. When the ozone generator is installed, the function of causing the water to flow toward the electrode quickly brings the electrode into a conductive state and instantly activates the ozone generator.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a cross-sectional perspective view showing the overall structure of an example of the ozone water purifier of the present invention.

The ozone water purifier 10 includes an upper housing 2o, a lower housing 40, and a side housing 60. The upper housing 20 has an air inlet 21 on the side of the lower end thereof and communicates with an air flow passage 22.

Furthermore, a power supply board 2 is disposed in the upper part of the upper housing 20.
A power supply circuit 24 fixed at 3 is provided, and this power supply circuit 24 generates a predetermined high voltage and high frequency current necessary for generating ozone in the ozone generating section 28.

One end of the power supply board 23 is fixed to a heat sink 25 arranged vertically. Further, the heat sink 25 is connected to a heat sink 26, and the heat generated in the power supply circuit 24 is transmitted to the heat sink 25 and the heat sink 26 via the power supply board 23, and is radiated there.

A drying filter 27 is arranged below the radiation fins 26, and the air that flows in from the air inlet 21 bypasses the radiation fins 26, passes through the inside of the drying filter 27, is dried there, and is removed from the ozone generating section. Sent to 28th. The ozone generator 28 has an ozone panel 29,
A creeping discharge occurs on the lower surface of the ozone panel 29, and ozone is generated here. The air sent to this ozone generating section 28 is dry, and no nitrogen oxides are produced during discharge, increasing the efficiency of ozone generation.

A dry air circulation port 30 is formed on the side of the ozone panel 29 of the ozone generator 28, and the ozone panel 29
An outflow port 31 is provided at the lower side of the holder. The dry air that entered the ozone generator 28 from the distribution port 30 contains ozone in the process of passing below the ozone panel 29.
It flows out from the outlet 31 as ozonized air.

On the other hand, an ozonized air flow passage 41 that communicates with an outlet 31 provided on the lower side of the ozone panel 29 is provided in a side portion of the lower housing 40 fixed under the upper housing 2o. .

The lower end of this ozonized air flow path 41 is connected to the ejector section 4
2, and since the ozonized air is sucked in this ejector part 42, air is sucked in through the air inlet 21 provided on the side of the lower end of the upper housing 20 via the ozone generator 28. Ru. A nozzle section 61 of the side housing 60 is disposed in the ejector section 42, and by ejecting water from the nozzle section 6l, the ozonized air in the ozonized air flow path 41 is sucked under reduced pressure. This nozzle portion 61 communicates with a water flow port 62, and by passing water from a tap water faucet 80 through this water flow port 62, pressure water can be supplied to the nozzle portion 61.

The ejector section 42 has an ozone water flow 44 at the bottom of the mixing chamber 43, which occupies most of the lower housing 40.
It is connected with the opening facing upward. Therefore, the ozonated water mixed with ozonized air in the ejector section 42 flows upward into the mixing chamber 43, so that the ozonated water stays in the mixing chamber 43. At the side bottom of the mixing chamber 43, an ozone water outlet 45 is arranged. Furthermore, a silver ceramic filter 46 is disposed in the mixing chamber 43, and the ozonated water in which ozone has been dissolved in the mixing chamber 43 passes through the silver ceramic filter 46, and silver ions are dissolved therein. The ozonated water flows from the ozonated water outlet 45 to the ozonated water discharge channel 47.
The ozone water is discharged from an outlet 48 formed by bending the ozone water discharge path 47.

An ozone removal filter 49 is detachably attached to the outlet 48, and if ozonated water is discharged with this ozone removal filter 49 attached, ozone is decomposed and removed, and purified water that does not contain ozone is made into a drinkable state. Supplied as water.

The ozone water purifier 1o of this embodiment is provided with an upper inner wall recess 52 near the upper corner of the bent portion 50 of the ozonated water discharge path 47 toward the outlet 48, and in this upper inner wall recess 52,
In addition to arranging a pair of electrodes 63, a so-called water guide portion 51 is provided at the lower corner of the bent portion 50, in which the bent end of the ozonated water discharge channel 47 is projected obliquely upward. ing. The ozonated water flowing through the ozonated water discharge path 47 hits the water guide portion 51, flows diagonally upward, and comes into contact with a pair of electrodes 63 disposed in the upper inner wall recess 52.

Further, the shape and size of the upper inner wall recess 52 is not particularly determined, such as a semicircle, a cylinder, a triangular pyramid, etc.

When the faucet 80 is opened to allow tap water to flow in from the water flow port 62, the ozonated water remaining in the mixing chamber 43 immediately flows from the ozonated water outlet 45 into the ozonated water discharge path 47, and the ozonated water discharge path 47 is exposed to the bent portion of the ozonated water discharge path 47. The ozonated water flows upward through the water guiding portion 5 disposed at the upper inner wall recess 50, contacts a pair of electrodes 63 disposed in the upper inner wall recess 52, makes them conductive, and passes through the wiring 64 to the upper housing 20. Power is automatically supplied to the ozone generator 28 via the power supply circuit 24 located in the ozone generator 28, and the generation of ozone is started.

From then on, by continuous supply of tap water from the water inlet 62,
Water flooded from the ozone water discharge channel 47 to the bent part 50,
The pair of electrodes 63 are always in contact with the ozonated water and maintained in a conductive state, so that ozone continues to be generated.

On the other hand, if the snake 080 is closed to stop the inflow of tap water from the water flow port 62, the inflow of ozonated water from the mixing chamber 43 to the ozonated water discharge path 47 is stopped, and the ozonated water discharge path 47 is stopped.
From there, water runs out at the bent portion 50, and the pair of electrodes 63 become non-conductive, so that the ozone generator 28 automatically stops and ozone is no longer generated.

The present invention utilizes the start and stop of water flow to the ozone generator 28 to turn on the switch in the ozone water purifier 10.
-This has been successful in automating the OFF operation. That is, by placing a pair of electrodes 63 that are not connected to each other in a part of the ozone water purifier 10 that is flooded with water when the water flow starts and becomes dry when the water flow is stopped, the electrodes 63 are brought into a conductive or non-conductive state and ozone water is purified. This has achieved automation of turning on and off the switch of the device.

In addition, by placing one of the pair of electrodes 63 in a region that is constantly submerged in water and the other electrode in a drought region when the water supply is stopped, the ozone water purifier 10 can be turned on and off automatically. It may be something that makes it possible.

The optimal position for a part that is flooded by water flow and becomes water-dry by stoppage of water flow is near the upper corner of the bent part 50 from the ozonated water discharge path 47 toward the discharge port 48. The arrangement of the electrode 63 is most preferable for the purpose of the present invention.

Furthermore, a recess of an appropriate shape and size is provided on the inner wall above the bent portion 5o, and this is used as the upper inner wall recess 52, and a pair of electrodes 63 or one of the pair of electrodes 63 is inserted into the upper inner wall recess 52. If it is housed, water will be quickly and accurately drained after the water flow is stopped, and the water supply will be turned off more reliably when the water flow is stopped.

In the present invention, the vicinity of the upper corner of the bent portion 50 is the so-called upper inner wall recess 52 provided in the upper inner wall, as described above.
It also includes.

As described above, when the electrode 63 is placed near the upper corner of the bent portion 50, the lower corner of the bent portion 50 is placed so that the electrode 63 can come into contact with water quickly after the water flow starts. A water guide portion 51 having a structure projecting obliquely upward toward the vicinity of the upper corner is provided. That is, the ozonated water that has flowed through the ozonated water discharge path 47 is directed to the water guiding section 51.
By flowing water toward the upper corner, the electrode 63 and water quickly come into contact with each other.

(Effects of the Invention) In the ozone water purifier of the present invention, power supply to the ozone generation mechanism is automatically started at the same time as water is flowing, ozone is generated, and water purified by ozone is supplied.

Furthermore, at the same time as the water flow is stopped, the power supply to the ozone generation mechanism is automatically stopped, and ozone generation is stopped. In this way, the ozone water purifier of the present invention is automatically turned on when the water flow starts, and automatically turned off when the water flow is stopped, so that purified water is not discharged due to forgetting to turn the switch on. Furthermore, the function of the ozone generator will not deteriorate due to continuous operation of the ozone generator for a long time due to forgetting to turn off the switch.

Furthermore, in the present invention, arranging the electrode in the recessed part of the upper inner wall of the bent part of the ozonated water discharge channel toward the outlet prevents ozonated water from remaining in the upper part of the outlet after water flow is stopped. Even if there is, the upper inner wall concave portion is reliably drained of water, so that the automatic switch mechanism of the present invention is accurately turned off.

Furthermore, the so-called water guide section provided at the lower corner of the bent section serves to quickly bring water into contact with the electrode placed in the upper inner wall recess, ensuring instantaneous and reliable operation of the ozone generator. shall be.
