Nanometer bubble generator

Abstract

The purpose of the present invention is to provide a nanobubble generator for bubbling dissolved oxygen contained in tap water into nano-sized micro-sized particles by means of pressure and vortex generated on the basis of the supply of the tap water and supplying the dissolved oxygen as laundry water, thereby improving the cleaning ability and improving the sterilizing effect.

Description

TECHNICAL FIELD

[0001] The present invention relates to a nanobubble generator which discharges gas bubbles in a super-microscopic form when discharging a liquid containing gas, particularly water in which air or oxygen is dissolved, and more particularly, to a nanobubble generator which not only easily applies a nanobubble generator composed of an inlet and an outlet to an existing pipeline facility of a washing machine or the like, but also enables laundry to be cleaned with nanobubbles. BACKGROUND

[0002] Generally, since a nanobubble has a high concentration of ozone and has a small size and a large surface area, more ozone can be brought into contact with bacteria, thereby exhibiting a strong sterilization ability.

[0003] When the value of dissolved oxygen is sharply increased, high dissolved oxygen can exert a sterilization or purification effect of water, thereby being able to inhibit the growth of harmful bacteria.

[0004] In order to use dissolved oxygen contained in water as described above, a bubble generator which generates oxygen bubbles with respect to water supplied to a washing machine has been proposed, and thus, a washing water is supplied with fine oxygen bubbles, thereby improving a cleaning ability and performing sterilization to some extent.

[0005] However, the bubble generator as described above does not use dissolved oxygen contained in water, but uses an oxygen bubble generator separately installed, and thus, requires a device for injecting additional oxygen bubbles such as gas or steam, thereby causing a high installation cost.

[0006] That is, the related art has only sought a solution for using a separate device to forcibly generate fine bubbles at a high cost to use a purification or sterilization effect of the fine bubbles, and research on a method for making dissolved oxygen itself into a micron-sized ultra-fine size and using the same has not been actively conducted. SUMMARY

[0007] Problems to be Solved by the Invention

[0008] The present invention has been made to solve the above-described related art problems, and provides a bubble generator which makes dissolved oxygen contained in tap water into a nanometer-sized micron by pressure and a vortex generated by supply of the tap water, and supplies the same as washing water, thereby improving a cleaning ability and making a sterilization effect excellent.

[0009] Method for Solving the Problem

[0010] To this end, the present application is characterized by comprising: a bubble generator body provided between a washing machine and a water supply pipe; a pressure reduction nozzle, which is built in the bubble generator body, to make tap water flowing through the water supply pipe to be discharged after the flow rate thereof is increased and the pressure thereof is reduced, thereby making air dissolved in the tap water be split into many small particles by the pressure reduction portion and be discharged; and a vortex generation nozzle to make the tap water discharged through the pressure reduction nozzle to generate a strong vortex again, thereby making bubbles be atomized into nano-sized tap water to flow into a water supply tank of the washing machine.

[0011] Effects of the Invention

[0012] The present application as described above has the following effects: the cleaning effect of laundry can be significantly improved by the powerful sterilization ability of very small bubbles, i.e., nano-bubbles, called ultra-micro bubbles, having a diameter of less than 1 μm.

[0027] First, referring to Figures 1 to 8 a nanobubble generator according to a first embodiment of the present application will be described.

[0028] As shown in Figures 1 to 8 , the nanobubble generator of the present application includes a bubble generator body 100 provided between a washing machine and a water supply pipe, a pressure-reducing nozzle 200 built in the bubble generator body 100 to generate minute bubbles, and a vortex-generating nozzle 300 to make tap water discharged through the pressure-reducing nozzle 200 generate a strong vortex, thereby making the tap water flow into a water supply tank of the washing machine.

[0029] The above bubble generator body 100 is connected between the washing machine and a water supply pipe connected to the washing machine, and has an inflow portion 102 and an outflow portion 104 formed in a shape through which the inflow portion 102 and the outflow portion 104 pass in the vertical direction, thread coupling portions 106 and 106a formed on the inner circumferential surface of the inflow portion 102 and the outer surface of the outflow portion 104, respectively, and a stepped step 108 formed in connection with the thread coupling portion 106.

[0030] The pressure-reducing nozzle 200 is coupled with the thread coupling portion 106 formed on the inner side of the inflow portion 102 in a threaded manner, and has at least three or more pressure-reducing portions 202 perforated radially from the center of the pressure-reducing nozzle 200, to increase the flow rate and reduce the pressure of tap water passing through the water supply pipe, thereby making air dissolved in the tap water be split into many small particles by the pressure-reducing portions 202 and be discharged.

[0031] The pressure reducing portion 202 is formed in a conical shape in which the cross-sectional area of the pipe through which tap water flows becomes narrower as the direction from the inflow portion 102 toward the outflow portion 104, and is formed such that the cross-sectional area of the pipe becomes wider at the outflow portion 104.

[0032] A thread coupling portion is formed on the outer circumferential surface of the inflow portion 102 side of the outer surface of the pressure reducing nozzle 200 to be coupled with the thread coupling portion 106 formed on the inner circumferential surface of the bubble generator main body 100, a plurality of fixing protrusions are protrusively formed on the outer surface of the outflow portion 104 side, and the vortex generating nozzle 300 is positioned on the fixing protrusions 204.

[0033] The vortex generating nozzle 300 has a plurality of helical blades 302 and passages 304, tap water flowing into the passages 304 collides with the blades 302 having inclined surfaces 306, the collision force generated by the collision of the fluid causes the gas components contained in the water to be split into smaller bubbles and a strong whirlwind to be generated, thereby discharging the tap water and supplying it to the washing tub.

[0034] When the pressure reducing nozzle 200 and the vortex generating nozzle 300 are coupled inside the bubble generator main body 100, the vortex generating nozzle 300 is supported by the step 108 formed inside the bubble generator main body 100 and is sequentially coupled, so that it can be firmly fixed inside the bubble generator main body 100 by the thread coupling method without a separate fixing device.

[0035] Accordingly, the nano bubble generator of the present application can significantly improve the washing effect of laundry using the powerful sterilization ability of nano bubbles called ultra-micro bubbles, and can be applied to a faucet or the like in addition to a washing machine, and can be effectively applied to various purposes.

[0036] As described above, the present application has been described with reference to the embodiments shown in the drawings, but these are merely exemplary, and it should be understood that various modifications and equivalent embodiments can be made by those skilled in the art based on the present application.

[0037] Accordingly, the true technical scope of the present application should be determined based on the technical scheme.
