Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a blowing device for a water heater, which operates a blowing portion such as a lead plate and a blowing hole by steam generated during boiling.

[0002]

[Prior art]

 Conventionally, Japanese Utility Model Publication No. 57-44900 has proposed a blowing device for a water heater that produces a harmonica sound when boiling. This is because a cover plate made of a flat plate is provided at the bottom of the lid with the lead plate inside, and the cover plate closes the pouring port. It makes a squeaking noise to notify boiling. It is also known that a resonance chamber provided with a blowing hole is provided in the lid to generate a blowing sound by the blowing hole by steam passing through the vapor hole of the closing plate at the time of boiling and at the same time resonate to notify boiling.

[0003]

[Problems to be solved by the device]

 In the above-mentioned prior art, since the closing plate is flat and the steam hole is formed in the center of the closing plate, there is a problem that the passage resistance of steam is large and the pressure loss is high.

According to the present invention, in a sounding device of a water heater, a cover plate having a steam hole at a lower portion of a lid closes a pouring port of the water heater and operates a sounding unit provided in the lid by steam. An object of the present invention is to provide a blowing device for a water heater that can reduce pressure loss.

[0005]

[Means for Solving the Problems]

 According to the present invention, in a blowing device for a water heater, a closing plate having a steam hole provided at a lower portion of a lid closes a pouring port of the water heater, and the blowing unit operates a blowing portion provided on the lid by steam. This is a blowing device for a water heater, which is formed so as to project upward and has the above-mentioned steam hole formed at the upper end of this closing plate.

[0006]

[Action]

 With the above structure, since the closing plate has a nozzle shape, the pressure loss of steam can be reduced.

[0007]

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. One side of the handle 2 is fixed to the upper portion of the water heater 1 via a mounting seat 3, and a spout 4 is provided on one side of the water heater 1. A lid 5 for closing the pouring port 4 and generating a harmonica sound is hollow. The lid 5 is provided with an operating lever 6A via an arm 6 and one side of the handle 2 via a hinge shaft 7. It is pivotally attached. Further, a spring plate 8 is cantilevered on the side of the mounting seat 3, and the base end side of the arm 6 is in contact with this spring plate 8. As a result, when the lid 5 closes the spout 4, the arm 6 is biased counterclockwise while the arm 6 is biased clockwise when the lid 5 is substantially vertical. Has become. The lid 5 is made of a cover plate 9 such as a stainless steel for closing the pouring port 4, a cover plate 10 made of synthetic resin that covers the upper side of the cover plate 9 and is integral with the arm 6, the cover plate 9 and the cover plate. It is composed of a lead plate 11 which is a blowing part provided between the ten. The closing plate 9 is formed in a spherical shape so as to project upward, and a steam hole 9A is formed at the upper end of the spherical surface portion 9B. Further, a groove 12 is formed in a ring shape at a portion of the closing plate 9 with which the spout 4 is brought into contact. The fitting portion 13 is integrally provided. A vapor discharge hole 10A is formed in the cover plate 10. Further, one end of the lead plate 11 is fixed to a partition plate 14 provided inside the lid 5, and is provided so as to close a communication hole 15 provided in the partition plate 14.

Next, the operation of the above configuration will be described. When the lid 5 closes the spout 4, the tip of the spout 4 is inserted into the groove 12 and the outer fitting portion 13 fits the spout 4 outside. When the hot water boils in such a state, steam is discharged to the outside through the spout 4, the steam hole 9A, the communication hole 15, and the steam discharge hole 10A. At this time, the steam in the pouring port 4 is guided by the closing plate 9 formed so as to project upward and reaches the steam hole 9A. Therefore, the lead plate 11 can be vibrated by the steam introduced from the steam holes 9A to generate a harmonica sound.

As described above, in the above-described embodiment, by forming the spherical portion 9B so as to project the closing plate 9 upward and forming the steam hole 9A at the upper end of the closing plate 9, the spout 4 Is gradually narrowed and reaches the steam holes 9A, so that the pressure loss is reduced, and the lead plate 11 can be vibrated well.

FIG. 3 shows a second embodiment of the present invention, in which the same parts as those of the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted. In the second embodiment, a sound is emitted by the resonance chamber 21, and a vapor discharge hole 10A is formed in the lid 5 and a vapor hole 9A is formed in the closing plate 9. The cover plate 9 is formed in a spherical shape so as to project upward, and a steam hole 9A is formed at the upper end of the spherical surface portion 9B.

Accordingly, the flow path of the steam from the spout 4 is gradually reduced by the closing plate 9 and flows into the resonance chamber 21, and then is discharged from the steam discharge hole 10A and blows to notify the boiling state.

The present invention is not limited to the above-described embodiment. For example, the shape of the closing plate may be a conical shape instead of a spherical shape, and in the above-described embodiment, the lid body can be rotated via the arm. Although it is shown as such, it may be handled as a single unit and detachably attached to the spout. The outer fitting part fits the outer circumference of the spout tightly or slightly loosely. Various modifications are possible.

[Effect of device]

 According to the present invention, in a sounding device for a water heater, a cover plate having a steam hole provided at a lower portion of a cover closes a pouring port of the water heater and operates a sounding part provided on the lid by steam. By forming the closing plate so as to project upward and forming the steam hole at the upper end of the closing plate, the pressure loss of the steam can be reduced and the sound can be emitted well.
