Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water purification device, and in particular, to making tap water more delicious by mixing water with air and irradiating it with electromagnetic waves such as far infrared rays and magnetism. Water purification equipment that can convert rainwater into drinking water and purify industrial water.

[Prior Art] Boiling, filtration, disinfection using chemicals, and the like are conventionally known methods for purifying tap water, rainwater, and groundwater.

Among these methods, the boiling method involves storing tap water or rainwater in a container and boiling it for a certain period of time to sterilize bacteria and other substances contained in the water.

In addition, the filtration method involves, for example, attaching a removable filter to a water faucet, and inserting a bacterial adsorbent or filter material such as activated carbon into the filter to eliminate harmful bacteria and other harmful substances contained in the water flowing through the filter. It filters substances.

Disinfection using chemicals is a method in which a predetermined chemical is added to water, such as tap water or a swimming pool, and the water is sterilized by the purifying power of the chemical.

[Problems to be solved by the invention] However, the boiling method described above not only requires heating means such as electricity or gas and is expensive, but also has the disadvantage that it takes time to cool down and cannot be used instantly. .

Filtration methods generally require periodic replacement as the adsorbent and filtration material deteriorates in their ability over time, which is time-consuming and, if used as is, bacteria may adhere to and multiply inside the filter. On the contrary, there is a risk of polluting the water.

In addition, methods using chemicals have a unique odor,
Particularly in recent years, it is said that one of the reasons why tap water is said to be unpalatable is because of this chemical smell. In addition, methods using chemicals have the disadvantage that they cannot be easily used in ordinary households.

Therefore, the present invention has conventionally proposed that when water and air are sufficiently mixed instantaneously, the oxygen in the air dissolves into the water and changes the physical properties of the water. Considering that a phenomenon known as aeration occurs, in which the water changes to water, it is possible to reduce the aeration by taking advantage of the fact that irradiation with electromagnetic waves such as far infrared rays and magnetism makes water taste better and transforms it into water with sterilizing power. The purpose is to provide a device that can further purify water by combining electromagnetic wave irradiation.

[Means for Solving the Problems] In order to achieve the above object, the water-freeness 7-forming device of the present invention is provided with a water flow channel in a housing provided with a water inlet and an outlet, and a water flow channel in the water flow channel. A constriction part is formed in which the passage is narrower than other parts, and an air inflow means for forcibly sending air into the constriction part by the flow velocity of water flowing into the constriction part, and an electromagnetic wave irradiation means for irradiating electromagnetic waves to the inner wall surface of the flow channel are provided. That's what happens.

[Function] With the above configuration, when the water purification device of the present invention is attached to, for example, a water faucet and the discharge pipe of the faucet and the inlet of the housing are connected, the flow rate of water flowing into the water channel when it passes through the throttle part is reduced. This increases the pressure, creating a negative pressure and forcing air into the constriction, where the water and air mix explosively and aeration occurs, increasing the amount of dissolved oxygen in the water and making the water less conducive to bacterial growth. Furthermore, the water is purified by changing the molecular energy level by ceramics or the like that irradiates electromagnetic waves on the inner peripheral surface of the flow channel.

[Example] Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a longitudinal cross-sectional view showing one embodiment of the water purification device of the present invention. In this figure, reference numeral 1 is the water purification device, 2 is a housing, and the housing 2 has a water inlet 3 and a water outlet 4.

This inlet 3 is communicated with a water supply source, for example, a discharge pipe 6 of a water faucet, via a connecting pipe 7.

The water flow channel 5 is provided with a constriction part 8 in the middle of which the passage is narrower than the other parts, and an air inlet means 9 for forcibly feeding air by the negative pressure generated by increasing the flow rate of water flowing through the constriction part 8. is provided.

In the illustrated example, the air inflow means 9 consists of a box 10 and a communication pipe 11 that connects the box 10 and the flow channel 5, and sucks air through an air intake port formed on the top or side surface of the box 10. The water is then fed into the flow channel 5 via the communication pipe 11.

If necessary, an air purifier such as a filter (
An air cleaner) may also be provided.

Reference numeral 12 denotes electromagnetic wave irradiation means provided in the flow channel 5, and the figure shows an example in which the circumferential surface of the flow channel 5 is coated with a far-infrared radiator such as ceramics.

As this far-infrared radiator 12, cordierite (2
Mg0・2Aldh・5SiO□), β spodumene (LL, O・A1□0.・4SiOz), aluminum titanate (Al□0.・Ti0z) and transition element oxide-based ceramics (for example, Mn0.60%, FezO5
20%, Cu010%, Co010%) is preferable.

In the illustrated example, the electromagnetic wave irradiation means 12 is installed near the constriction part 8 so that aeration and electromagnetic wave irradiation can be performed at the same time. It may be done before aeration, or
Conversely, it may be provided near the outlet 4 and carried out after aeration.

Reference numeral 13 denotes a chamber provided on the side of the outlet 4 from the constriction part 8, which stops the force of the water flowing in the flow channel 5 and allows the water and air to mix in the chamber to perform a sufficient aeration effect. It is something.
