Description

[Detailed Description of the Invention] [Purpose of the Invention] (Field of Industrial Application) The present invention relates to a whistle device for kettles, pots, etc. that makes a sound when boiling.

(Prior Art) A whistle kettle disclosed in Japanese Utility Model Application Publication No. 56-62721 is known as a kettle of this type. This whistling kettle is equipped with a lid that incorporates a flute in the spout so that it can be opened and closed freely, and the lid is biased to move up and down with a leaf spring. It makes a continuous sound. Also known as 53-4920
In the publication, the lid of the kettle is provided with a flute body having a flute hole, and this kettle also makes a flute sound continuously as the boiling occurs.

The kettle that blows while the kettle is on a fire is noisy, so in recent years, kettles that stop blowing and exhaust steam have been introduced, such as in Publications No. 62-3065 and No. 4274. It has been proposed. These kettles selectively connect the flue body and the exhaust hole to the steam outlet hole.

(Problem that the invention aims to solve) Not only kettles with whistles that do not allow you to select the whistle, but even kettles that allow you to select the whistle will be noisy until you move the kettle away from the fire. There were some problems that made it difficult to use.

One way to solve these problems is to
It is possible to reduce the continuous whistling sound, but if it is reduced, it will not be possible to notify boiling.

The present invention has been made based on the above-mentioned problems, and an object of the present invention is to provide a kettle that can reliably and quietly notify boiling without reducing the volume.

[Structure of the invention] (Means for solving the problem) A lid body 15 having a whistle hole 13 is attached to the exhaust port 1 so as to be openable and closable, and the lid body 15 is provided with an opening/closing force adjustment device 16 for intermittent blowing. .

(Function) When the steam pressure pulsates, the lid 15
opens and closes, and at the same time, the whistle hole 13 generates a blowing sound when it is closed, and stops the blowing sound when it is opened, so that the blowing sound can be generated intermittently.

(Embodiment) Fig. 1 shows a first embodiment, in which 1 is a spout of a kettle body 2 which is an exhaust port, and a lid body 3 made of heat-resistant synthetic resin is attached to the opening of the spout 1. Installed so that it can be opened and closed freely. An outlet hole 4 is formed in the upper center of the lid main body 3, a cavity 5 is formed in the lower part, and a mounting protrusion 6 is provided vertically downward. Further, a mounting arm portion 3A is integrally extended to one side of the lid body 3.
The distal end of the attachment arm portion 3A is pivotally attached to an attachment seat 7 fixed to the kettle body 2 near the spout 1 by an attachment shaft 8. Reference numeral 3B denotes a diagonally upward operating lever section that extends further to one side of the mounting arm section 3A.

Reference numeral 9 denotes a partition plate made of flat steel that closes the bottom of the cavity 5 of the lid main body 3, and a bottom plate 11 made of a concave steel plate is inserted below the partition plate 9 via the cavity 10.
to be placed. The edges of these partition plates 9 are clamped to the edges of the lid body 3 and the bottom plate 11, and the bottom plate 11
is a male screw 12 that is screwed into the mounting protrusion 6 from below.
The lid main body 3, the partition plate 9, and the bottom plate 11 constitute a lid body 15. Furthermore, a flute hole 13 and an inlet hole 14 are formed in the partition plate 9 and the bottom plate 11 so as to be substantially coaxial with the outlet hole 4.

16 is a lid body 15 whose center of rotation is the mounting shaft 8;
This is an opening/closing force adjustment device for intermittent blowing that adjusts the moment of
6A is formed on the mounting arm portion 3A, and the screw hole 16
A balance weight 16C is fixed to the tip of a male screw hole 16B that is screwed into A.

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

When the water stored in the kettle body 2 boils, the steam pressure increases, and the steam is exhausted to the outside through the inlet hole 14, whistle hole 13, and outlet hole 4, and a whistling sound is generated when passing through the whistle hole 13. The whistle resonates in the cavities 5 and 10 and indicates boiling. At this time, balance weight 1
6C is moved back and forth to adjust the lid 15 to open and close intermittently in accordance with the steam pressure within the kettle body 2.
That is, when the balance weight 16C of the intermittent blowing opening/closing force adjustment device 16 is advanced, the torque around the mounting shaft 8 becomes smaller, and when the balance weight 16C is moved backward, the torque around the mounting shaft 8 becomes larger. The torque adjustment is set so that the lid 15 is intermittently opened and closed in accordance with the steam pressure.

Therefore, the next time you boil water, a weak whistling sound will be produced when the water boils, and as the whistling sound gradually becomes louder, the lid 15 will lift up and the steam will be exhausted directly from the spout 1, resulting in a silent state.When the steam pressure weakens, the lid will close. The body 15 is closed, and the steam flows through the inlet hole 14 and the whistle hole 1.
3. A whistling sound is generated as the air is exhausted through the outlet hole 4. When the internal pressure of the kettle body 2 rises again, the lid 15 opens. By intermittently opening and closing the lid 15 in this way, the whistle sound can be reduced to "piyo...
You can make a sound like “piyo…piyo…”. After notifying boiling in this manner, the kettle body 2 is removed from the stove, the operating lever part 3B is pushed down to open the spout 1, and hot water is supplied to a pot or the like.

As described above, by providing the lid 15 incorporating the flute hole 13 with the intermittent blowing opening/closing force adjustment device 16 that adjusts the moment of the lid 15, it can be opened and closed according to the internal pressure of the kettle body 2. As a result, the whistling sound can be generated intermittently, and boiling can be reliably notified, and the intermittent sound does not cause any noise.

Furthermore, since the opening/closing force adjustment device 16 is adjusted by screwing the male threaded portion 16B of the balance weight 16C into the screw hole 16A, the opening/closing force can be finely adjusted. That is, the steam pressure etc. may change based on the amount of water stored in the kettle body 2, and in this case, the intermittent blowing can be set or finely adjusted by the opening/closing force adjustment device 16 for intermittent blowing. As a result, the interval between the intermittent sounds can be set to a desired time.

Moreover, since the lid body 15 is pushed up by steam pressure immediately after being closed, the spout 1 and the bottom plate 11 are in gentle contact, and there is no unpleasant noise caused by metal contact.

FIG. 2 shows a second embodiment, which is a box-shaped whistle box with a whistle hole 13 at the bottom of the lid body 3, which has an outlet hole 4 for opening and closing the opening of the spout 1 of the kettle body 2. 21 is fixedly installed to constitute the lid body 15. A mounting arm portion 3A is connected to one side of the lid body 15, and an operating lever portion 3B is extended diagonally above the mounting arm portion 3A. Furthermore, a mounting seat 7 for pivotally mounting the mounting arm portion 3A via a mounting shaft 8 is fixedly provided near the spout 1, and an opening/closing force adjustment device 22 for intermittent blowing is provided at the rear of the operating lever portion 3B. .
This opening/closing force adjustment device 22 for intermittent blowing includes a coil spring 22A whose one end is connected to the operating lever portion 3B.
The other end is connected to the tip of an adjustment screw 22B, and the adjustment screw 22B is screwed into the handle 23 so that it can move forward and backward. Therefore, when adjusting screw 22B is moved forward, the tensile force of coil spring 22A is weakened, while when adjusting screw 22B is moved backward, the tensile force of coil spring 22A is increased. In this way, the opening/closing force of the lid body 15 is adjusted to make a whistling sound intermittently as the internal pressure of the kettle body 2 increases.

As described above, the lid body 15 is controlled by the intermittent blowing opening/closing force adjustment device 22 using the coil spring 22A.
By adjusting the moment around the mounting shaft 8, the opening/closing force can be adjusted over a relatively wide range with a compact structure.

It should be noted that the present invention is not limited to the above-mentioned embodiment; for example, it may be attached to the exhaust port 32 of the lid 31 of the pot as shown in FIG. Various modifications are possible, such as allowing the signal to be emitted.

[Effects of the invention] The present invention provides a lid that incorporates a flute hole in an exhaust port such as a spout so that it can be opened and closed freely, and the lid is equipped with an opening/closing force adjustment device for intermittent blowing, thereby reducing the internal pressure. The lid can be opened and closed as the kettle rises, generating an intermittent whistling sound, which can reliably notify boiling and eliminate noise. Furthermore, by adjusting the opening/closing force adjustment device for intermittent blowing, the kettle The intermittent state can be set or this state can be adjusted depending on the steam pressure inside the tank.
