【Example】

 Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings. As shown in FIG. 1, the blowing device 1 of the present invention is attached to a pouring port B 1 of a kettle A having a lid C. The sounding device 1 is composed of a tubular main body 2 and a closing plate 13 which is locked to the lower end of the cylindrical main body 2, and the closing plate 13 is provided with an opening / closing arm 14. -The shaft hole provided in the arm 14 is fixed to the bearing provided outside the spout B, and the opening / closing arm 14 is operated to operate the closing plate 13 and the cylindrical main body 2 attached thereto. And rotate and tilt to open and close the spout B.

As is clear from FIGS. 2 and 3, the tubular main body 2 is composed of a tubular body in which a short tubular portion 3a and a long tubular portion 3b are formed in series, and a bottom central portion thereof is provided. In addition to the shaft hole 11 to which screws can be screwed, the lead supporting member 4a is mounted in the short tubular portion 3a, and the lead supporting member 4b is mounted in the long tubular portion 3b. The inside is divided along the cylinder length direction to form inflow-side division chambers 8a and 8b and outflow-side division chambers 9a and 9b each having a semicircular cross section.

Thus, the upper portions of the inflow-side compartments 8a and 8b are closed by the closing members 6a and 6b at the upper ends of the lead supporting members 4a and 4b.

Further, blow holes 5a and 5b are formed in the center of the lead supporting members 4a and 4b by means of vertically long slits, and the lead holes 5a and 5b are connected to the inflow side compartments 8a and 8b, respectively. Lead plates 7a and 7b made of a copper alloy or the like are attached to the surface of the door supporting member by tacking means.

As shown in FIG. 4, the back surface of the tubular main body 2 having such a structure has a shaft hole 11 opened at the center, and the short tubular portion 3a and the long tubular portion 3b are connected to the lead supporting member. The inflow-side compartments 8a and 8b and the outflow-side compartments 9a and 9b, which are formed by being partitioned by 4a and 4b, are open, and their contours are elliptical.

The elliptical minor diameter portion is provided with engagement pins 10, 10 projecting from the lower part of the outflow side compartments 9a, 9b to the lower peripheral wall of the tubular main body 2 directly. There are provided two guide grooves 12a, 12a and two guide grooves 12b, 12b communicating with the lower peripheral wall of the tubular main body 2 via the guide grooves 12c, 12c.

On the other hand, the closing plate 13 is formed by attaching the opening / closing arm 14 to an elliptical plate body slightly larger than the contour shape of the lower portion of the tubular main body 2, as shown in FIG. A through hole 15 is formed in the center, engagement holes 17, 17 are provided in the minor diameter portion, and semicircular steam ejection holes 16a, 16b are provided in the major diameter portion.

The cover plate 13 is attached to the lower part of the cylindrical main body 2 by passing through the central through hole 15 and screwing a screw 18 into the shaft hole 11 of the cylindrical main body 2. As a result, the engagement pins 17, 10 of the tubular main body 2 are engaged with the engagement holes 17, 17 of the closing plate 13 and positioned so as not to rotate, and at the same time, each inflow-side compartment of the tubular main body 2 is positioned. The steam ejection holes 16a and 16b are aligned with the lower openings of 8a and 8b, respectively. Further, each guide groove 12a, 12b, 12c of the tubular main body 2 forms a drainage hole 19 that opens to the lower peripheral wall of the tubular main body 2 by mounting the closing plate 13, and this drainage hole 19 is a short cylinder. Two blades are formed on both sides of the portion 3a and two blades are formed on both sides of the long tubular portion 3b.

Therefore, when the blowing device 1 is attached to the pouring port B of the kettle A, the inside of the kettle A is the vapor of the cover plate 13 when the blowing device 1 closes the pouring port B (the state of FIG. 1). It communicates with the inflow side compartments 8a, 8b of the cylindrical main body 2 through the ejection holes 16a, 16b, and the outflow side from the blowout holes 5a, 5b through the lead plates 7a, 7b of the lead supporting members 4a, 4b. It is connected to the compartments 9a and 9b and communicates with the atmosphere through the opening at the upper end of the outflow compartments 9a and 9b. Also, the opening / closing arm 14 of the closing plate 13 is operated to open the spout B. The open state disconnects the steam communication from the kettle A to the sounding device 1.

Then, when the spout B is closed by the blowing device 1 and the water in the kettle A is boiled, the generated steam goes through the above-mentioned path and is attached to the lead supporting members 4a and 4b. The control plates 7a and 7b are vibrated to emit a predetermined sound to warn the user of the boiling state.

In this case, the blowing mechanism is incorporated in the cylindrical main body 2 extending upward, and the lead plates 7a and 7b for generating vibration are formed of a plate body such as a copper alloy extending in the vertical direction. Therefore, it is possible to play a wide range of sounds, such as the sound of a standing flute, and it is possible to generate an excellent sound that is different from the sound of conventional flutes.

Here, in the blowing device 1, when the steam generated from the kettle passes through the outflow-side compartments 9a and 9b, the steam that comes into contact with the inner surface is condensed and drops as water drops. At this time, since the cylindrical main body 2 is maintained in a substantially upright state, the water droplets generated in the outflow-side compartments 9a and 9b do not take a complicated route and quickly flow downward to stop the blowout, No abnormal noise is generated and a clear sound can be sustained.

The water droplets flowing down from the outflow side compartments 9 a and 9 b are caught by the closing plate 13 and discharged from the drainage hole 19 through the guide groove 12, but the spout B is moved by the blowing device 1. In the closed state, the liquid is discharged from the two drainage holes 19 on the side of the short cylinder 3a, and when the pouring port B is opened, it is promptly discharged from the two drainage holes 19 on the side of the long cylinder 3b. The harmful substances contained in the copper alloys and the like forming the lead plates 5a and 5b are not brought into the kettle A by water droplets. Since the generated steam hardly condenses into water droplets in the inflow side compartments 8a and 8b, it is not necessary to form a guide groove or the like for drainage.

[0022]

[Effect of device]

 Since the structure of the blowing device of the present invention is a vertical whistle type, the tone range of the tone is widened so that an excellent tone can be secured, and the length and shape of the tubular main body can be adjusted to the shape of the kettle. It has the advantage that it can be designed freely.

Further, since the vertical whistle type structure makes it possible to prevent the water droplets generated when the steam is jetted, no abnormal noise is generated and a good timbre can be ensured.

Further, since the above water droplets are configured to be discharged to the outside without returning them to the kettle, it is possible to ensure safety in hygiene.
