Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a blowing device for a water heater that makes a sound using a reed plate due to the jetting action of generated steam.

(Conventional technology) A blowing device that uses a whistle to notify when water has boiled is
Sometimes it can be heard as a sharp, unpleasant sound. For this reason, it had a harmonica sounding mechanism that produced a mellow tone, that is, it was used as a blowing device that vibrated the reed plate.
No. 3 is publicly known. This blowing device has a hollow lid that is shaped to close the spout of a water heater, and a steam flow passage that releases steam that has flowed in from the spout to the outside, and a steam flow passage inside the hollow lid. A reed plate sounding mechanism is incorporated in the middle of the steam passage during the flow of steam, and the hollow lid is equipped with a shield and a drain hole to divert water droplets that have condensed on the reed plate etc. from the steam path and discharge them to the outside. It is.

Also, Publication No. 62-3061, Publication No. 59-
Publication No. 39971, Publication No. 58-55717, and Publication No. 58-55717
In Publication No. 60-28340, etc., a steam inlet is formed in the lower part of a hollow lid body that closes the spout, and a steam outlet is formed in the upper part, and a vertical steam flow path between the inlet and the outlet is formed. A blowing device equipped with a reed plate is disclosed.

(Problem to be solved by the invention) However, in the former conventional technology in which the shielding body and drain hole are provided, in order to drain the dew condensation generated inside the hollow lid body to the outside, a lead plate made of copper alloy such as brass is used. Although the harmful patina that occurs can be prevented and the water heater can be kept sanitary, all of the condensation that occurs inside the hollow lid flows down from the drain hole along the outer periphery of the spout, resulting in dripping. There is a risk that the nozzle of the gas burner may become clogged due to this dripping.

In addition, in the latter prior art, steam passes through a vertical steam flow path and is exhausted from the steam outlet at the top, so the handle near the spout is easily heated by the steam exhausted from the top, and the handle near the spout is easily heated. There was a problem in that water droplets were not discharged from the steam outlet and were likely to accumulate inside the hollow lid.

The present invention was developed in consideration of the above problems,
To provide a blowing device for a water heater which can discharge dew condensation generated inside a hollow lid body to the water heater side, prevent water droplets from adhering to a reed plate, and improve drainage performance inside the hollow lid body.

Next, the operation of the above structure will be explained.

When steam is generated during boiling water, it flows into the hollow lid 5 through the spout 4 and the steam inlet 18. After colliding with the partition wall 11, this steam flows into one hollow chamber 14 while being rectified through the steam guide path 13 of the horizontal steam flow path 21, and while vibrating the reed plate 17, the blow hole 16, The steam is discharged to the outside through the steam outlet 6A. A portion of the steam passing through the steam guide path 13 passes through the escape hole 15A and is directly exhausted from the steam outlet 6A. On the other hand, water droplets condensed on the lead plate 17, lead support plate 15, etc. drip onto the closing plate 7 as the lead plate 17 and lead support plate 15 are tilted, flow backward through the steam guide path 13, and are poured out from the steam inlet 18. Drop into mouth 4.

At this time, the elastic plate 25 is attached to the central portion 10A of the support shaft 10.
The hollow lid body 5 is pressed against the spout 4 to keep them in close contact with each other to eliminate leakage of steam. That is, the elastic plate 25 urges the hollow lid 5 in a counterclockwise direction.

Next, when pouring hot water, first rotate the operating body 8 in the direction of the arrow, and the hollow lid body 5 will be separated from the spout 4.
At the same time, the support shaft 10 also rotates in the direction of the arrow against the elasticity of the elastic plate 25 and the top plate portion 9B, and the elastic plate 25 comes into pressure contact with the central portion 10A of the support shaft 10, and the surrounding shell plate 6
comes into pressure contact with the top plate portion 9B and holds the hollow lid body 5 in an upright state. That is, the elastic plate 25 urges the hollow lid body 5 in a clockwise direction. Then, grasp the handle 2 and pour boiling water from the spout 4.

When the hollow lid 5 is rotated in the opposite direction again, the hollow lid 5 comes into contact with the spout 4.

According to the embodiment described above, the closing plate 7 of the hollow lid body 5 containing the reed plate 17 is provided at the spout 4, and the steam flow passage 21 is formed horizontally between the steam inlet 18 and the steam outlet 6A, A lead plate 1 is attached to the hollow lid body 5.
7 and the reed support plate 15 are installed obliquely, water droplets adhering to the reed plate 17 etc. are pushed up by the unidirectional steam pressure from the blow hole 16 through the horizontal steam flow passage 21, and the steam flow is increased. It can be discharged to the outside from the outlet 6A. The water droplets pushed up at this time flow down toward the steam outlet 6A side as the lead plate 17 and lead support plate 15 are tilted. In addition, when the steam pressure is relatively low, water droplets condensed inside the hollow lid 5 can drip into the spout 4 from the steam inlet 18 due to the slope, so drainage is excellent and the reed plate 17 Reliability can be improved, and dripping caused by water droplets adhering to the outer periphery of the spout 4 can be prevented.

Further, the hollow chamber of the hollow lid body 5 is divided into two parts by a partition wall 11, and the partition wall 11 is provided opposite to the steam inlet 18, and furthermore, a steam guide path 13 is provided.
, the steam flowing in from the steam inlet 18 can be rectified, and the lead plate 1 is
7 vibration frequency change can be prevented and a pleasant sound can be generated.

Moreover, since the reed plate 17 is provided on the back side of the reed support plate 15, there is less water droplet adhesion to the reed plate 17, and a beautiful tone can be produced. Furthermore, the width of the steam flow passage 21 is narrowed due to the partition wall 11. As a result, the steam becomes high-pressure and is blown onto the reed plate 17, so that the reed plate 17 can be vibrated by the high-pressure steam, and the reed plate 17 can be reliably sounded. Furthermore, by forming the escape hole 15A between the lead support plate 15 and the surrounding shell plate 6, a part of the steam passes through the escape hole 15A, and water droplets inside the hollow lid body 18 are discharged from the steam outlet 6A. Furthermore, when washing the water heater with water, water droplets in the hollow lid body 5 can be immediately drained.
Therefore, there is no need to drain the water heater for a long time, and it can be used at any time.

FIG. 5 shows a second embodiment, in which the same parts as in the first embodiment are denoted by the same reference numerals, and detailed explanation thereof will be omitted.

The support shaft 10 is a crank-shaped rod, and narrow portions 24 that engage with the notched grooves 23 are formed near both ends thereof, and the center portion is pressed against a U-shaped elastic plate 41. One end of the elastic plate 41 is placed on the tongue piece 9D, and the other end is arranged so as to be able to come into pressure contact with the central portion 10A of the support shaft 10. Therefore, when the center of the support shaft 10 is located near the other end of the elastic plate 41 as shown by the two-dot chain line in FIG. As shown, when the elastic plate 41 is pressed against the center portion 10A, the hollow lid body 5 can be biased clockwise.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and various modifications can be made, for example, by providing a plurality of lead plates having different natural frequencies. For example, as shown in FIG.
The bent portion 25B may be fitted into the groove 25C so that the elastic plate 25 contacts the center portion 10A of the support shaft 10 with a predetermined pressure. An elastic plate may be welded and fixed.
Furthermore, the spout may be round.

[Effects of the invention] The present invention is provided in the spout of a water heater so that it can be opened and closed freely, and installed horizontally between the steam inlet formed at the base end of the closing plate and the steam outlet formed at the tip of the surrounding shell plate. By forming the steam flow passage and slantingly disposing it on the reed plate, it is possible to prevent water droplets from adhering to the reed plate and improve drainage performance within the hollow lid.
