Abstract

        The purpose of this invention is to make microbubble bubble functional water rich in negative ions and dissolved oxygen by forcibly incorporating air into fluids such as tap water (commonly referred to as fluids) commonly used in our lives. To achieve this goal, we have designed a microbubble generating inverter that can control the flow rate and flow rate of the fluid and incorporate air. Microbubble Creation When the inverter was designed, it was based on utilizing the force of the fluid itself. To this end, it applies the law of continuous and Bernoulli theorem in fluid mechanics to control the flow velocity of fluid, induce the pressure difference, and induce the movement of air. We have devised a microbubble generating inverter with a characteristic structure, such as the end structure of the air suction nozzle that comes into contact with the fluid when the air is mixed, and the effective mounting direction of the air suction nozzle.

        Designed Micro Bubble Generation The fluid passed through the inverter becomes a functional water rich in negative ions and bubbles (air, dissolved oxygen). The functional water is fast with positive ion contaminants (generally speaking, the contaminants have positive ion properties, which interact and bind with negative ions). Combined and bound contaminants are separated more quickly from contaminants by bursting microbubbles. As a result, the water passed through the micro-strength generating inverter has the effect of reducing the use of chemical detergents (such as shampoo, rinse, soap, etc.). In addition, the irritation on the skin is reduced, which helps to manage the skin, scalp and hair effectively.

        In addition to these actions, it also saves fluid by the amount of air (dissolved oxygen, etc.) entrained in the water. Comparing the number of passes through which air is mixed with the number of passes through the hole of the air inlet nozzle makes the number of passes through the air inlet nozzle feel much lighter than the normal water. And, depending on the water pressure, the amount of fluid used is reduced by 15-25%. As a result, the microbubble generating inverter has the primary effect of saving the passing fluid and increasing the cleaning power by increasing the negative ions. In addition, the reduction of the use of chemical detergents, etc. can be expected to prevent secondary environmental pollution to reduce environmental pollution. This design is a green environment energy saving water treatment device that proactively copes with energy saving and environmental pollution.

Description

 Micro air bubble creation inverter

        The present invention forcibly incorporates air into fluids such as tap water (commonly referred to as fluids) that are commonly used in our lives to create micro-bubble bubble functional water rich in negative ions and bubbles (air, dissolved oxygen). There is a purpose. The basic premise of the present invention is that it must not be an externally dependent device that operates by externally supplying power such as a high pressure pump or air compressor. In other words, it is a device for the production of micro bubble generating inverters (hereinafter referred to as inverters) that operate by the flow rate of the fluid itself without borrowing external energy. The present invention first creates a flow velocity variation structure that converts the flow velocity of the fluid into its own power. At a certain point of the designed flow variation structure, the flow velocity is increased and the air pressure in the accelerated part becomes a relatively low pressure state compared to atmospheric pressure. The air inlet nozzle is mounted at a certain point in the induced low pressure state. Equipped air inlet nozzles allow air at normal atmospheric pressure to flow into a low velocity flow rate structure and at the same time contact fluid. Continuous law and Bernoulli's theorem application technology of fluid mechanics about the connection device that allows the inflow of air due to the velocity change of the fluid and the pressure difference to make the treatment water rich in negative ions and bubbles (air, dissolved oxygen) Field.

        Previously, Inverters typically used pressurized or injection techniques to incorporate air (dissolved oxygen) into the fluid. The pressurized type is designed to pressurize the fluid directly through the high pressure pump to increase the flow rate and induce air pressure difference from the atmospheric pressure through this. The injection type is designed to mix air by making an air injection pipe into a pipe through which the fluid passes and blowing high pressure air directly into the air compressor. However, the methods mentioned above have limitations due to their compactness, and there is a problem of the limitation of the place of use and the high cost of using a mechanical device such as an expensive high pressure pump or an air compressor.

        Even recently developed non-powered small microbubble products have a problem that fluid flows back to the air inlet pipe depending on the water pressure during actual use or when the microbubble generating inverter is lower than the final discharge port. In addition to this, there is a disadvantage in that the suction sound is excessively large when inhaling air.

        Therefore, it is based on the Inverter that utilizes potential energy of the fluid itself without using high pressure pump or air compressor that uses external energy, and air flows smoothly even at low water pressure, and the height of the final discharge port is increased. We started to develop Inverter which has a certain effect even if it is higher than Inverter.

        The background art of the present invention is basically the field of continuity law and Bernoulli's theorem in hydrodynamics. The law of continuity and Bernoulli's theory are fundamental theories explaining flight principles. In other words, the paraglider, the hang glider, or the plane that can fly in the sky is based on the following theorem and Bernoulli's theorem.

        First, the law of continuity states that if a fluid flows through the same pipe, the mass of the fluid entering per unit time at the inlet and the fluid exiting through the outlet must be equal. Therefore, if the inlet cross section is A1, the speed is V1, the outlet is A2 and the speed is V2, the following equation is established. A continuous equation of "A1 V1 = A2 V2 = constant" is derived, indicating that the velocity and cross-sectional area of the fluid is inversely proportional as it flows through the tube. Therefore, by adjusting the inner diameter of the same pipe, you can control the speed of the fluid.

        The Berunui Theorem states that if the pressure of a fluid acting the same magnitude in all directions is called static pressure (P) and the pressure generated by the velocity of the fluid is dynamic pressure (q), The equation of P + q = Pt is established between the total pressure (Pt), the pressure acting on the plate when it is blocked at right angles, which means that the pressure (static pressure) and the speed (dynamic pressure) are inversely proportional to each other. Therefore, adjusting the inner diameter of the same pipe regulates the velocity of the fluid, which in turn means that the pressure can be controlled.

In this design, the above-described theory is applied to complete the structure of the optimum inverter through actual experiments and simulations. As a result of the actual experiment of Inverter, the noise generated by the inflow of outside air through the air inlet nozzle is so loud that it may cause discomfort during use. Therefore, a noise barrier is installed at the top of the air inlet nozzle. In addition, a check valve was devised inside the air inlet nozzle to fundamentally block backflow leakage caused by water pressure and height of discharge port.
Incorporating the various steps as described above, the present invention utilizes the law of continuity and Bernoulli's theorem of fluid dynamics to utilize the potential energy of the fluid itself rather than the conventional external dependent device, and blocks the inhalation sound generated during air inhalation. In order to eliminate the phenomenon of backflow to the air inlet, a check valve was devised structurally to achieve a design different from the conventional method.

        The problem to be solved in the present invention is ① Inverter that sucks air by itself without external power energy supply ② Inverter that can be directly applied to household pipes such as tap water ③ Even when the height of discharge port is higher than Inverter, the minimum water pressure is 0.1kg / In the case of ㎠, the height is up to 50cm and if the minimum water pressure is more than 0.8kg / ㎠, the air is introduced even at the height of more than 100cm. Development ⑤ Development of parts with the structure that the maximum air is sucked in when the end of the air inlet nozzle is in contact with the fluid.

        In the present invention, in order to reduce the trial and error without actually experimenting with the invention to solve the technical problem, we have found the solution through the following process using the simulation program on fluid mechanics.

        The present invention is intended to achieve the results of the invention with the following technical problems to solve the above problems.

        First, in order to develop an Inverter that inhales air by itself without supplying external energy, it decided to use the law of continuity and Bernoulli's theorem in hydrodynamics as a theoretical background. The law of continuity tells us that when a collinear fluid flows through a tube, the velocity and cross-sectional area of the fluid are inversely proportional. Therefore, by adjusting the inner diameter of the same pipe, the speed of the fluid can be controlled. At the same time, Bernoulli's theorem is that pressure (static pressure) and speed (dynamic pressure) are inversely proportional to each other. Therefore, adjusting the inner diameter of the same pipe regulates the speed of the fluid, which in turn means that the pressure can be controlled. Based on this theoretical foundation, we utilized the Bernoulli's calculation application from Gorge State University in Canada, where we could simulate the real world.

        ② In order to develop an Inverter that can be directly applied to household pipes such as water supply, the connection part of the Inverter is adjusted to the tap size based on the simulation of ① above, and at the same time, the inside diameter of the inlet is less than 12mm, and the flow rate is increased to 5mm. The length is designed to be within 110mm.

        ③ Even if the height of the discharge port is higher than the Inverter, the air inlet nozzle is developed to develop the Inverter that the air flows even if the minimum water pressure is 0.1kg / ㎠ and the height is 50cm when the minimum water pressure is 0.8kg / ㎠ or more. The tube diameter is set to 1mm or less and the outside diameter is set to 3mm or less. For the air inlet nozzle, we chose to install the air inlet nozzle developed in ④ at 2/3 of the inner diameter of 5mm in the flow velocity increasing part of ①. Inverters made in this way have the effect of getting enough air even if the height of the outlet is high.

        In order to solve the problem, it is designed as a check valve type with a ball valve inserted into the air inlet of the upper part of the air inlet nozzle. The internal space of the ball valve is designed as a check valve type that has the effect of suppressing the generation of noise when air is introduced and blocking the back flow directly on the back water pressure when the water flows back.

형으로 고안된 끝단부는 - 자형의 끝단부 보다 유체와 공기 접촉 면을 넓히는 결과를 가져왔고 목표하는 수준의 공기가 흡입되어 음이온(-)과 기포(공기, 산소)가 풍부한 통과수가 되었습니다. ⑤ At the beginning of the design, when the fluid contact end of the air inlet nozzle was manufactured in a straight shape and applied to the product, the inflow of air was not constant and bubbles were not generated. In order to increase the volume of air inlet by increasing the contact surface between the end of the air inlet nozzle and the fluid, and to create a structure in which a large amount of air is sucked, the end of the air inlet nozzle diameter is

By cutting the mold, the end of the air inlet nozzle is mounted at 4mm from the 5mm inner diameter so that it is perpendicular to the flow of the fluid. As a result,

The end designed in the form of a-resulted in a wider fluid and air contact area than the end of the shaped, and the target level of air was sucked in, which resulted in the passage of water rich in anion (-) and bubbles (air, oxygen).

        This design applies the structure of the Venturi tube using the law of continuity and Bernoulli's theorem. The structure of the venturi tube induces a change in the flow rate of the fluid itself without supply of external power. Rapidly varying flow rates create a low pressure inside the venturi tube. Atmospheric air (oxygen, etc.) is sucked into the venturi tube under low pressure. Inhaled air (oxygen, etc.) comes into contact with the fluid to form functional water containing micro-bubbles rich in negative ions and bubbles (air, dissolved oxygen). Inverter developed like this expects the following effects.

        First, it's an energy-saving device that doesn't require any external power.

       Second, it creates a functional water containing micro-bubbles rich in negative (-) ions and air (oxygen), increasing cleaning power and having a light and soft touch.

       Third, the passing water through the Inverter increases the cleaning power by increasing the negative ion. This effect reduces the use of detergents (shampoo, rinse, etc.) while also providing sufficient cleaning power, which has the effect of reducing environmental pollution.

       Fourth, the volume of fluid increases as bubbles are generated, which is an energy-saving water treatment device that has a direct effect of saving 15 to 25% of the discharged water depending on the water pressure.

       Fifth, it is convenient to install and use because it does not use air compressor or high pressure pump.

       Sixth, it has a thermal effect when the bubble bursts.

        Detailed description of the accompanying drawings of the present invention is as follows. We started with some basic assumptions for the invention of this invention.

        First, it was technically based on not using high pressure pump or air compressor that uses external power energy.

        Second, we studied how to harness the potential energy of the fluid itself through the device to save energy.

        Third, the product had to flow in smoothly even at low water pressure (less than 1kg / ㎠) or high water pressure (more than 4kg / ㎠) to generate bubbles and have high field adaptability.

        Fourth, in principle, the fluid does not flow back even if the height of the final discharge port is higher than the intended product.

The maximum pipe diameter of the influent does not exceed the passage diameter of the tap water as shown in the inlet (1) of Figure 1 so that it can be applied to the shower pipe or hose connected to the water pipe or the water pipe. In addition, the diameter of the flow rate increasing part (3) in FIG. In addition, in accordance with the inner diameter of the Bernoulli tube shown in FIG. 1, the flow rate increasing part 3 and the flow rate increasing part 3 and the inner diameter 5 mm of the mounting point 4 of the air inlet nozzle of FIG. The outer diameter of the connecting part was 3mm and the inner diameter of the air suction hole was 1 mm or less. Figure 1 air inlet nozzle (6) is widened to the fluid connection portion so that the maximum air flow in Figure 2

Specially designed as type (6-4). In fact, Figure 1 is a specially designed ∧ shape or ∩,

The nozzle (6) had a significant difference in air flow and bubble generation compared to the normal nozzle (-shaped).

         1 Inverter is designed to be within 110mm in length considering the connection point. Within the range of 110mm, Figure 1 inflow (2) has a diameter of 12mm and 40mm, and Figure 1 flow rate increasing section (3) has a diameter of 70mm from the beginning of the 5mm diameter (7) to 5mm. In the device designed in this way, the flow velocity of the fluid in the portion of FIG. Although the air inlet nozzle was installed at the half point of the 5 mm part Bernoulli tube with the higher speed, the air inflow was not allowed and the fluid flowed back to the air inlet nozzle depending on the position of the final outlet of the water pressure or the passing water.

The simulation program equation (http://hyperphysics.phy-astr.gsu.edu/hbase/pber.html#beq) of the Bernoulli equation at Gorge State University in Canada is used to identify the point where the flow velocity As a result, it was most effective to install the Fig. 1 air inlet nozzle (6) from the starting point (5) of the Bernoulli tube of Fig. 1 to the point 2/3 (4) of the Fig. 1 Bernoulli tube. In the early stage of the design, the air inlet nozzle of the general flat (-shaped) shape was tested at the 2/3 point (4). 2, the fluid contact end 6-4 of the air inlet nozzle is

Designed and manufactured as a type. 2 is a ∧ type or 부의 of the end of the air inlet nozzle,

Nozzles made with molds (6-4) were placed parallel to the fluid and did not produce satisfactory air input. At the end of the trial and error, as shown in Fig. 1, the shape or shape of the end 6-6 of Fig. 2,

The nozzle was placed at right angles to the direction of fluid in Fig. 1, and the end of the air inlet nozzle (6-4) was positioned at 4mm inside the Bernoulli tube inner diameter of 5mm. As a result of the experiment, the air flowing through the air inlet nozzle increased steadily and did not flow back even when the fluid pressure was low.

          Inverter designed with this achievement

        Firstly, air inflow starts from 0.1kg / ㎠ without the backflow caused by water pressure, and the higher the water pressure, the more air flows into the target effect.

        Secondly, in the initial performance that is operated only when the position of the final discharge port is lower than that of the inverter, the result is sufficient air inflow even when the position of the final discharge port is significantly higher than that of the inverter.

        The water passed through the Inverter was able to finish the washing or washing in a short time with the excellent washing power when washing or washing the hair, which saved water consumption. It also makes the skin feel very soft and comfortable.

And the end of the air inlet nozzle 6 in contact with the fluid of FIG.

After designing as type (6-4), it was installed in the Bernoulli tube with the fastest flow rate and the lowest pressure. As a result of this selection, it was possible to artificially create a low pressure state lower than atmospheric pressure most efficiently under various conditions regardless of flow rate or height of discharge section. This resulted in the efficient introduction of atmospheric air (dissolved oxygen) into the fluid. In addition, the introduced air (dissolved oxygen) passes through the Inverter and is mixed with the fluid to generate bubbles and create a functional water rich in the desired negative ion. Through this process, we completed a small inverter, an energy-saving green environment product that produces discharge water containing micro bubbles.
