Description

[Technical Field]

[0001] The present invention relates to a swirl flow generator for supplying fine bubble water. [Background technology]

[0002] Various nozzles and hoses have been proposed to generate and supply fine bubbles to devices that use tap water, such as shower heads and washing machines. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 7089342 (Drawing, Figure 1) Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned microbubble generator is said to be able to effectively generate microbubbles derived from cavitation due to its structure.

[0005] However, although the above-mentioned invention is expected to produce a cavitation effect, it has a problem in that it claims to effectively generate microbubbles.

[0006] In view of the above-mentioned problems inherent in the prior art, the present invention provides a swirl flow generator that can be attached to the water supply section or the middle of the water supply pipe of an appliance that uses tap water, such as a shower head or a washing machine, and that supplies aerated water containing a large number of fine bubbles to such appliances. [Means for solving the problem]

[0007] The swirl flow generator of the present invention is mainly composed of a substantially cylindrical pipe 1 and a swirl flow generating unit 2. The pipe 1 has structural parts 3 for external connection at both ends of the pipe, and has threads 5, grooves 6, or steps 7 on the inside of the pipe from the water inlet side 4 toward the center, so that it can fit with the parts that make up the swirl flow generating unit. The swirl flow generating unit 2 has a plurality of adjacent circular or polygonal plate-like parts 10 with threads 8 or protrusions 9 or the like on their sides, which are parallel to the inner surface of the pipe. The plate surface of each part 10 has a plurality of funnel-shaped holes 11 to form a flow channel, and each of the holes 11 is angled obliquely in a predetermined direction so that the flowing water swirls. A connecting structure is also provided in which a plurality of agitation spaces 13 for the flowing water are provided between the parts 10 via spacers 12 or the like. [Effects of the Invention]

[0008] According to the present invention, the swirling flow generating section is integrated into the pipe, making the structure extremely simple. Furthermore, the mechanism of the swirling flow generating section distributes the agitation space for the flowing water, thereby suppressing the concentration of excessive water pressure changes caused by cavitation, and the device is also highly durable, and is expected to supply bubbly water containing a greater number of fine bubbles.

[0009] Furthermore, by changing the size, funnel-shaped hole diameter, direction, and angle of each of the multiple components that make up the swirling flow generating section during manufacturing, it is possible to generate complex swirling flows with varying strengths and forward and reverse directions of flowing water.
