Description

Technical Field

[0001] The present invention relates to a hose incorporating a microbubble generator. When a liquid such as tap water flows through the hose, microbubbles can be generated and contained in the liquid discharged from the hose by a cavitation method from gases such as air dissolved in the liquid.

Background Art

[0002] Research on microbubbles started around 1985. Since microbubbles are a new technical field, there are still many points that have not been clarified. Currently, the following two phenomena are known about microbubbles.

[0003] One is the penetration phenomenon that easily enters deep into fibers, pores, etc. because of the small size of microbubbles. The other is collapse. Collapse is a phenomenon in which microbubbles are discharged into water, are crushed by the water pressure in the water, become even smaller nanobubbles, and are eventually destroyed. When this collapse occurs, ultrasonic waves at about 400 km / h are generated, and it is said that extremely high heat of nearly 5500 degrees is generated. And it is said that dirt and the like are easily removed by the interaction of these two phenomena.

[0004] Here, as means for generating microbubbles, about nine types are known, such as a high-speed shear method, a pressure collapse method, a cavitation method, etc. Most of them use an aspirator method or the like to suck air from the outside or forcibly inject it. The cavitation method is a method of generating microbubbles using the cavitation phenomenon (cavity phenomenon) that occurs in the flow of a liquid.

[0005] 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 in which a gas is dissolved, and comprises a cylinder having a groove drilled on its outer circumference and a microbubble generation channel through which the liquid passes and generates microbubbles, and an elastic O-ring fitted into the groove, and is arranged in a liquid delivery pipe that flows the liquid to a place to be delivered, and the O-ring seals the space between the liquid delivery pipe and the cylinder.

[0006] 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.

[0007] It does not have a microbubble generator. As an example of a hose, Figure 3 shows a washing machine hose 10 (excerpted from Non-Patent Literature 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 onto 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 used to secure the microbubble generator inside the present invention. [Prior art documents] [Patent Documents]

[0010] Therefore, the present invention aims to provide a microbubble generating hose that incorporates a microbubble generator, which, when a liquid such as tap water flows through the hose, generates and incorporates microbubbles into the liquid discharged from the hose by a cavitation method from gases such as air dissolved in the liquid. [Means for solving the problem]

[0011] Furthermore, in order to solve the above problems, the present invention provides: (1) A microbubble raw hose characterized by comprising a hose and a microbubble generator fixed inside the hose, through which a liquid passes, and equipped with a channel for generating microbubbles from gases dissolved in the liquid by a cavitation method. (2) The microbubble generating hose according to (1), characterized in that the fixing is by crimping. (3) The microbubble generating hose according to (1), characterized in that a recess is provided on the outer circumference of the microbubble generator. (4) The microbubble generating hose according to (3), characterized in that a protrusion is provided in the recess. (5) A microbubble generating hose according to any one of (1) to (4), characterized in that a space is provided upstream of the microbubble generator, and a tornado plate having eccentric holes for swirling the liquid and increasing its flow velocity is placed in the space. (6) The microbubble generating hose according to (5), characterized in that a ring is placed on the upstream side of the tornado plate to smooth the flow of the liquid to the tornado plate. (7) A microbubble generating hose according to any one of (1) to (6), characterized in that it is used for any one selected from among a washing machine hose, a shower head hose, a water supply hose for a heated toilet seat, a pull-out hose for a kitchen or bathroom faucet, and a car wash or high-pressure cleaning hose. This was the configuration. [Effects of the Invention]

[0012] Because of the above configuration, the present invention provides a microbubble generating hose that incorporates a microbubble generator, and when a liquid such as tap water flows through the hose, microbubbles are generated and incorporated into the liquid discharged from the hose by a cavitation method from gases such as air dissolved in the liquid. With such a microbubble generating hose, simply by connecting it to a water tap and passing tap water through it, microbubble-containing water can be discharged from the hose.

[0013] By providing a microbubble generating hose as a washing machine hose, it is possible to continuously supply microbubble-containing water to the washing machine tub simply by connecting it between the faucet and the washing machine, or by replacing the existing hose, thereby enhancing the cleaning effect.

[0014] The microbubble generation hose of the present invention can be used not only for washing machines, but also as the hose of a shower head, the water supply hose of a warm water washing toilet seat, the pull-out hose of a faucet fitting in the kitchen or washroom, and further as a hose for car washing or high-pressure cleaning.

Embodiments for Carrying out the Invention

[0016] Hereinafter, the present invention will be described in detail based on the attached drawings. Note that the present invention is not limited to the following examples.

Examples

[0017] As shown in FIG. 1, the microbubble generation hose 1 of the present invention is composed of a hose 2 and a microbubble generator 5, and may further include a toroidal plate 6 and a ring 7.

[0018] The hose 2 can be exemplified by a washing machine hose 10, etc., and may be provided with joints 3 and nuts 4 at both ends. Note that the numerical values shown in mm in FIG. 1 are examples of the lengths of each component.

[0019] Here, the attachment of the joint 3 to the faucet connection 9 is, as shown in FIGS. 1 and 3, while pressing the lever 3b, with the cover 3a pushed downwards, insert it into the faucet connection 9 attached to the faucet 8, hang the tip 3c of the lever 3b on the flange 9a of the faucet connection 9, and connect the water supply hose 10a to the faucet 8 for use.

[0020] The microbubble generator 5 is built into and fixed inside the hose 2, and has a channel 5a through which liquid discharged from the faucet 8 passes, generating microbubbles from gases dissolved in the liquid using a cavitation method.

[0021] The flow path 5a consists of a first flow path 5b whose inner diameter gradually narrows from the liquid inlet end towards the center, a cylindrical second flow path 5c connected to the first flow path 5b, and a third flow path 5d connected to the second flow path 5c whose inner diameter gradually widens towards the liquid outlet end.

[0022] Examples of fixing the microbubble generator 5 inside the hose 2 include crimping 2a fastened from the hose 2. The microbubble generator 5 has a recess 5e on its outer circumference to form a step 5f, making it difficult for the microbubble generator 5 to move inside the hose 2. Furthermore, by providing a protrusion (not shown) in the recess 5e, the position of the microbubble generator 5 is made even more difficult to move. In addition, if the protrusion is tapered in a wedge shape in the direction of insertion of the microbubble generator 5, the position of the microbubble generator 5 is further stabilized.

[0023] The tornado plate 6 is located upstream of the microbubble generator 5 with respect to the liquid flow, and as shown in Figure 2, it consists of a disc-shaped body 6a and four holes 6b that penetrate the body 6a vertically and horizontally, for example, 15° off-center, in order to rotate the liquid and create a swirling flow to increase the flow velocity. The body 6a can be made, for example, by molding resin.

[0024] Ring 7 is positioned upstream of the tornado plate 6 relative to the liquid flow, thereby smoothing the liquid flow to the tornado plate 6. [Explanation of Symbols]
