Abstract

<P>PROBLEM TO BE SOLVED: To attain a pleasant feeling of a shower without a spray board by solving the problems of the conventional shower head wherein a spray board with a plurality of holes should be provided on a water discharge opening part, and when the water is discharged like a shower and the end of a rubber hose is crushed to spray water in order that the water is discharged from the end of the rubber hose without the spray board, the flow velocity increases and the water is discharged at strong water pressure, but a water current is fine not to be used as a shower. <P>SOLUTION: In the water discharge opening of a shower, although a water flow passage is narrowed to increase the flow velocity by utilizing the principle of a rubber hose, in order to further increase the flow velocity before that, a member for generating a vortex in flowing water is built in an inlet part of the water flow passage, thereby further increasing the flow velocity at a narrow part of the water flow passage while the water current is twisted, and the flowing water is discharged suddenly like a spray at the water discharge opening part to secure a pleasant feeling of a shower. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to the shape of the water outlet that replaces the general shower head connected to the tip of the shower hose, and has a simple structure that does not require a water spray plate at the water outlet, like the shower head. It is the structure of the water discharge port part which made it possible to spread and spray water in a spray form while the water discharge flow swirls along the opening wall of the water discharge port part spreading in a trumpet shape.

In a conventional shower head, the water flowing from the shower hose passes through the grip of the tubular shower head and passes through each hole of the water spray plate where a plurality of holes are opened. As a result, the number of holes drilled in the water spray plate, the diameter of the holes, and the shape of the holes were important factors that influenced the shower experience.

Japanese Patent Laid-Open No. 11-57535 JP 2003-265351 A JP 2003-310468 A JP 2006-239106 A JP 2008-229516 A

  A spray-like water spray is provided so that a comfortable shower experience can be obtained without a water spray plate, and a spout can be attached to the tip of the shower hose.

  While adding a twist as a swirling flow at the inlet of the main body to the flowing water flowing in from the shower hose, the inner diameter is narrowed to increase the flow velocity, and it is further diffused in a spray form along the inner wall of the spout opening. The water outlet is constructed so that a comfortable shower experience can be obtained, although it is different from the shower discharged from the plurality of holes of the water spray plate.

  In order to create a so-called drum-like structure that gradually expands again after the inner diameter of the water passage at the water outlet is gradually narrowed, it can be made integrally with a resin or a casting, or a trumpet shape. A drum-like structure may be made by making two cylinders and connecting them at the mouth of each trumpet.

  In order to increase the flow velocity, the flow channel is narrowed in a tapered shape so that the diameter decreases from the inlet side to the outlet side, and the flow rate is further increased so that a smooth flow can be achieved by providing a disk-like shape at the inlet portion of the flow channel. In the plate, a plurality of twisted holes are opened in the plate, and a member for forcing a swirling flow in the flowing water is incorporated.

  By intentionally making irregularities on the trumpet-shaped inner wall of the spout for diffusing the spout in the form of a spray, turbulence is caused in the spout and the shower experience is improved.

  The inner wall of the trumpet pipe that is twisted by the plate at the inlet of the water flow channel and passed through a narrowed portion that narrows in a tapered shape while swirling the flowing water, increasing the flow velocity and spreading it in a trumpet shape. The water can be diffused in the form of a spray to be discharged while being swirled along, and a sensible experience similar to that of a shower can be ensured even without a watering plate.

  The connection part of the trumpet-shaped tube for making the drum-shaped water passage may be connected with the same size of the caliber, but may be connected with different sizes, in which case the inner diameter of the outlet side at the connection part By increasing the pressure, the pressure of the flowing water is suddenly released into the air, or conversely, the inner diameter of the outlet side of the connection part is narrowed, so that the water flow other than the central part of the water flow that has passed through the water passage is narrower on the outlet side. It was different from the conventional shower with a multi-perforated water spray by making it turbulent in the running water so that it hits the wall around the tunnel opening and then suddenly opening it into the air. A shower experience can be obtained.

  In addition, when warm water of about 40 degrees is passed through the device with the water outlet of the device submerged in water, the air contained in the warm water is compressed through the narrow portion at high speed while swirling, and then When the pressure is suddenly released into the water and the pressure drops, fine bubbles are generated together with the water discharged in the water. Thereby, the effect as an apparatus which produces | generates a fine bubble in water was also able to be confirmed.

  By changing the total area of the diameters of the openings of the twisted holes and the twist angle of the holes, which are opened in the disk-shaped plate member for causing the swirling flow, the flow velocity and the twist angle of the water flow are changed. Can do. In the experiment with the prototype, the shape of the disk-shaped plate was 13.5 mm in diameter, but this was because the diameter of the water / hot water supply pipe was 15A, and the size is not limited. Further, the twisted water channel opened in the disk-shaped plate may be tapered so that the diameter decreases from the inlet side toward the outlet side.
