Claims (5)

  1. It consists of a hose through which a liquid, such as tap water , flows, and a microbubble generator fixed inside the hose, which has a channel through which the liquid passes and generates microbubbles from gases dissolved in the liquid using a cavitation method. The position of the microbubble generator within the hose is fixed by crimping the hose from the outside against the microbubble generator. A microbubble generating hose characterized by having a stepped portion provided by creating a recess in the portion of the outer circumference of the microbubble generator that presses against the hose with the crimp, thereby preventing the microbubble generator from moving within the hose at the stepped portion.
  2. The microbubble generating hose according to claim 1, characterized in that a protrusion is provided in the recess to suppress the movement of the microbubble generator.
  3. The microbubble generating hose according to claim 1, characterized in that a space is provided upstream of the microbubble generator, and a tornado plate, which has eccentric holes for swirling the liquid and increasing its flow velocity, is placed in the space.
  4. The microbubble generating hose according to claim 1, characterized in that the hose is one of the following selected from a washing machine hose, a shower head hose, a water supply hose for a bidet toilet seat, a pull-out hose for a kitchen or bathroom faucet, and a car wash or high-pressure cleaning hose.
  5. The washing machine hose consists of a hose through which a liquid such as tap water flows, a joint at one end of the hose that can be attached and detached with a single touch to a water supply connector attached to a faucet, and a nut at the other end that screws onto the water supply valve screw of the washing machine body via an elbow, and a microbubble generator fixed inside the hose, which has a channel through which the liquid passes and generates microbubbles from gases dissolved in the liquid using a cavitation method. The position of the microbubble generator within the hose is fixed by crimping the hose from the outside against the microbubble generator. The microbubble generator is characterized by having a stepped portion provided by creating a recess in the portion of the outer circumference of the crimp that presses against the hose, thereby preventing the microbubble generator from moving within the hose. Microbubble generating hose for washing machines .

Description

This invention relates to a hose incorporating a microbubble generator, which, when a liquid such as tap water flows through the hose, generates and incorporates microbubbles into the discharged liquid from gases such as air dissolved in the liquid using a cavitation method. Research on microbubbles began around 1985. Because microbubbles are a relatively new technological field, many aspects remain unexplained. Currently, the following two phenomena are known regarding microbubbles: One phenomenon is the penetration effect, where the small size of microbubbles allows them to easily reach deep into fibers and pores. Another is collapse. Collapse occurs when microbubbles are released into water, crushed by the water pressure, becoming even smaller nanobubbles, and eventually bursting. It is said that this collapse generates ultrasonic waves traveling at approximately 400 km/h and produces extremely high temperatures of nearly 5500 degrees Celsius. The interaction of these two phenomena is said to make it easier to remove dirt and other impurities. Here, about nine methods are known for generating microbubbles, including high-speed shearing, pressure collapse, and cavitation. Many of these methods, such as aspirators, draw in or forcibly inject air from an external source. The cavitation method, in particular, generates microbubbles using the cavitation phenomenon (cavity phenomenon) that occurs in a liquid flow. The present inventor has already invented a cavitation-type microbubble generator described in Patent Document 1. The microbubble generator of Patent Document 1 is a microbubble generator that generates microbubbles from a liquid containing dissolved gas, and comprises a cylinder with grooves drilled on its outer circumference and a microbubble generation channel through which the liquid passes to generate microbubbles, and an elastic O-ring fitted into the grooves. The generator is positioned within a liquid delivery pipe that carries the liquid to a destination, and the O-ring seals the space between the liquid delivery pipe and the cylinder. However, the invention described in Patent Document 1 involves cutting or removing the piping upstream of the faucet spout for installation, which is a cumbersome process. Furthermore, it needs to be removed for replacement and maintenance. On the other hand, Patent Document 1 did not consider means for installing a microbubble generator built into a hose. As an example of a hose without a microbubble generator , Figure 3 shows a washing machine hose 10 (excerpted from Non-Patent Document 1, "2. Connecting the water supply hose to the washing machine body"). The washing machine hose 10 has a joint 3 attached to one end of the water supply hose 10a by crimping 3d, which can be attached and detached with a single touch to a water supply connector 9 attached to a faucet 8, and an elbow 4a fixed to the water supply hose 10a by crimping 4b, which has a nut 4 that screws into the water supply valve screw 11a of the washing machine body 11. The washing machine hose 10, consisting of these components, is versatile and can be attached and detached to washing machines from a wide variety of manufacturers. The washing machine hose 10 is an example of a hose that fixes the microbubble generator inside according to the present invention.
