Description

[Detailed Description of the Invention] The present invention relates to a lid for a water heater equipped with a reed blowing device for notifying boiling of water.

Conventionally, there is a lid body of this type as shown in FIG. 1, for example.

That is, the steam jet tube 21 attached to the lid body 20
A brass flute plate 22 is fixed horizontally to the top of the
A brass reed 24 is fixed in a cantilever manner to one end of several ventilation holes 23 provided in the flute plate 22, and a hollow knob 25 is attached to the steam jet tube 21. No. 24 has been plated on the entire surface to prevent the occurrence of blue edges.

When the water boils, the high-pressure steam is discharged through the steam jet tube 21 and into the knob 25 from the vent 23, and the sound generated by the vibration of the reed 24 as it passes through the vent 23 causes the water to boil. This is to inform the public.

Incidentally, water droplets adhering to the whistle plate and reed are one of the factors that affect the blowing effect of the reed, but the whistle plate 22 and the reed 24 in the conventional example are attached horizontally to the upper part of the steam jet tube 21. Because there are
The problem was that the attached water droplets were difficult to fall off, and the blowing effect was not sufficiently exerted.

In view of the above points, the present invention aims to suppress the adhesion of water droplets to the flute board and reed, and to simplify the replacement of the flute board with a reed. explain.

In FIG. 2, reference numeral 1 denotes a container body of a water heater, and a spout 2 is watertightly attached to the front of the container, and a handle 3 is fixed to the rear upper part by rivets or the like.

Reference numeral 4 designates a spout lid for opening and closing the spout 2, which is rotatably supported by a pivot pin 6 on a bearing plate 5 attached to the container body 1, and is recessed in the lower surface of the front inclined portion 3a of the handle 3. It is connected by a connecting pin 8 to one end of an operating arm 7 that moves forward and backward within the provided U-shaped hole 3b.

Reference numeral 9 denotes a substantially C-shaped leaf spring mounted between the bearing plate 5 and the connecting pin 8, and the connecting pin 8 is attached to the bearing plate 5 when the spout cover 4 is in the open/closed position. This functions to restrict the opening/closing position of the spout lid 4 as it is set beyond the dead point connecting the base and the pivot pin 6.

Reference numeral 10 denotes a lid made of synthetic resin, and as shown in FIG. 3, a bowl-shaped bulge 10b is formed from the periphery of a circular opening 10a formed in the center, and a knob 10c is formed from the bulge 10b. is formed over the outer peripheral edge of the lid body 10.

Also, the bulging portion 10 on the opposite side to the above-mentioned knob portion 10c
Several steam exhaust holes 10d are formed in the vertical direction in b, and a fitting part 10e with the container body 1 is formed on the lower surface of the outer peripheral edge of the lid 10.

As shown in FIGS. 2 and 4, the bowl-shaped swollen portion 10b has an inverted U-shaped wall formed by vertically cutting the swollen portion 10b facing the steam exhaust hole 10d. A guide groove 10f for inserting the flute board is formed in the thick surface, and a cylindrical part 10g having a screw for fixing the flute board cover is vertically provided in the center, and a plurality of dew condensation holes are formed on the side of the knob 10c. A ridge 10h is provided vertically in the shape of a hair brush.

11 is an inverted U-shaped whistle plate with multiple steam vents 1
1a are arranged in parallel, and the base of the lead 12 is attached in a cantilevered manner to the lower end of the ventilation hole 11a.

Since the adhesion of water droplets to the flute plate 11 and reed 12 occurs when high-temperature and humid boiling steam hits the flute plate 11 and reed 12 and cools down, the present invention uses a material with good heat conduction. The flute plate 11 and the reed 12 are made of a material such as aluminum.

Reference numeral 13 denotes a flute plate cover made of stainless steel or synthetic resin that fits into the circular opening 10a.A stepped flange 13a is formed on the outer periphery, and the upper surface is tapered lower from the center toward the outer periphery. , a circular hole 13b for screw insertion facing the cylindrical portion 10g, and a plurality of steam flow holes 1 facing the protrusion 10h.
3c is bored, and a positioning protrusion 13d that abuts one side of the lower edge of the flute plate 11 is formed (in the case of stainless steel, it is a cut-and-raised piece).

Next, to explain the assembly and operation of the above blowing device, as shown in FIGS. 2 and 4, the whistle plate 1
1 into the guide groove 10f of the bowl-shaped swollen portion 10b, and insert the flute plate cover 13 into the circular opening 1 of the lid body 10.
0a to engage the flange 13a with the outer peripheral edge of the opening 10a. At this time, the protrusion 13d is attached to the whistle plate 1.
1, and screw the screw 14 into the threaded portion of the cylindrical portion 10g through the circular hole 13b.

Therefore, since the flute board 11 is installed vertically, the reed 12 is also installed with its free end facing upward.

When the water in the water heater boils, high-pressure steam flows out from the flow hole 13c of the whistle plate cover 13 between the plurality of protrusions 10h provided in a hairbrush shape, and flows out from the ventilation hole 11a of the whistle plate 11. Through the discharge hole 1
It is discharged to the outside from 0d, and boiling is notified by the sound produced by the vibration of the reed 12 when passing through the ventilation hole 11a.

Therefore, the flute plate cover 13 existing in the steam outflow path performs a primary dew condensation action, and then the plurality of protrusions 10h performs a secondary dew condensation action, so that the flute plate 11 and the reed 12 are is exposed to low-moisture air, and the flute plate 11 and reed 12 are made of aluminum material with good heat conduction, and the flute plate with the free end of the reed facing upward is installed vertically. , it is difficult for water droplets to adhere, and even if they do, they will quickly flow down the flute board and from the free end, which is the vibrating part of the reed, to the lower mounting part, even if the flute board is installed vertically. Compared to cases where the free end of the reed points downward, the falling water droplets collect at the free end of the reed, the adhesion of water droplets to the free end is significantly reduced, causing the reed to blow. The effect can be improved.

Since the upper surface of the flute plate cover 13 is tapered, the dropped water drops flow out through the discharge hole 10d and the circulation hole 13c as shown by the arrows, and do not accumulate inside.

Furthermore, since the reeded whistle board 11 can be easily assembled using the screws 14, its replacement is extremely easy.

Furthermore, as another embodiment of the above-mentioned flute board and reed, when a material such as aluminum with good thermal conductivity is treated with fluorine resin, the adhesion of water droplets can be further suppressed and the free end of the reed can be prevented from sticking. In combination with the vertical arrangement of the flute plate, which is attached facing upward, it is possible to more effectively prevent water droplets from adhering.

As described above, in the present invention, the flute plate and reed are made of aluminum material with good heat conduction or aluminum material treated with fluorine resin, and the free end of the reed is attached to the lid body with the free end facing upward. Since the flute board is mounted vertically, the reed blowing effect can be fully demonstrated, making it extremely valuable in practical use.
