[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a boiling water state notification device for audibly notifying how much hot water is boiling in a container in a cooking device such as a kettle or a pan.

[0002]

[Prior art and its problems]

 A whistle-type or reed-type whistle-blow kettle that uses vapor pressure is known as a signal that the boiling water of a kettle has boiled. However, this was an inconvenience when it was used because the kettle spout had a whistle lid.

There is also known a device in which a heat sensor and an electronic circuit for sounding are provided, and boiling of hot water is detected by heat to generate a sound. But this was expensive.

[0004] Further, examples of utilizing a bell include those described in JP-B-36-6071 and JP-B-35-9558. These used an elastic body such as a spring for power, and were structurally extremely complicated and difficult to put into practical use.

Further, any of the above-mentioned ones does not operate until the vapor pressure or temperature reaches a certain level or more, and various states of boiling water, that is, boiling is in an initial state or is the most severe. It was not enough to know if it was in a state.

[0006]

[The purpose of the device]

 It is an object of the present invention to provide a boiling water state notification device capable of giving a sound indication of how much hot water is boiling.

[0007]

[Means for achieving the purpose]

 The boiling water state notification device of the present invention is an information device provided outside the container for notifying sound of the boiling water state in the container. It is characterized in that it is composed of an impeller that rotates in a rotating manner and a sounding body that emits sound by striking each other as the impeller rotates. It is composed of a striking member that is swingably attached to the end and a striking member that is provided around the impeller.

[0008]

[Action]

 When the hot water in the container boils, steam spouts from the spout hole, the impeller rotates, and the sounding body makes a sound as the fan wheel rotates. The strength of the ejected steam corresponds to the state of boiling water, the impeller rotates at a speed corresponding to the strength of the ejected steam, and the sounding body produces a sound with a strength corresponding to the rotation speed of the fan wheel. , The state of boiling water is known from the strength of the sound.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a kettle adopting the boiling water state notification device of the present invention, and FIG. 2 is a partial vertical sectional view of the kettle shown in FIG. The alarm device 10 of the present invention is attached to the top of the lid 2 of the kettle 1. 2b is a knob of the lid 2.

FIG. 3 is an exploded perspective view of the notification device 10. In FIG. 3, 11 is a steam ejection hole. Two ejection holes 11 are formed on the horizontal top surface 2a of the lid 2 at 180 degrees from the center. A support shaft 12 is provided vertically at the center of the top surface 2a. A spacer 13, an impeller 14, a spacer 15, a cover 16 and a knob 17 are attached to the support shaft 12 in this order. The impeller 14 is made of, for example, aluminum, is rotatably attached to the support shaft 12, and receives steam from the ejection holes 11 to rotate. The cover 16 is made of copper, for example, and is provided with the lower peripheral edge thereof slightly covering the spacer 15, the impeller 14, and the spacer 13 so that the lower peripheral edge of the cover 16 is fixed to the support shaft 12 so as not to rotate. ing. The knob 17 is attached to the upper end of the support shaft 12.

The impeller 14 is composed of a plurality of blades 14 a, and a ball 22 is attached to an outer end portion of a certain blade 14 a via a ring 21. On the other hand, the peripheral wall 16a surrounding the impeller 14 of the cover 16 is provided with one convex portion 23 protruding inward. The convex portion 23 is formed so as to project so as not to contact the blade 14a. A large number of through holes 24 are formed on the upper surface of the cover 16. In this embodiment, the ball 22 and the convex portion 23 of the cover 16 constitute a sounding body.

Next, the operation will be described. When the hot water in the kettle boils, steam spouts from the spout hole 11, and the impeller 14 receives this steam and rotates. When the impeller 14 rotates, the balls 22 also rotate around the support shaft 12. The ball 22 collides with the convex portion 23 of the cover 16 while rotating, and thereby a sound is generated. After passing through the impeller 14, the steam is discharged from the through hole 24.

The intensity of the generated sound corresponds to the rotation speed of the impeller 14. The rotation speed of the impeller 14 corresponds to the strength of the steam that is ejected. The strength of the ejected steam corresponds to the boiling state of the hot water in the kettle, that is, the boiling water state. Therefore, the state of boiling water can be known from the strength of the generated sound. When the rotation speed of the impeller 14 is high, the generated sound is loud (strong).

Since the ball 22 is provided via the ring 21, it can be swung freely with respect to the impeller 14, and even if the ball 22 collides with the convex portion 23, the ball 22 is caught by the convex portion 23. It does not inhibit the rotation of 14.

Since the through hole 24 is formed in the cover 16, the sound generated by the ball 22 colliding with the convex portion 23 is not muddy in the cover 16.

[Another embodiment]

 Although the notification device 10 is adopted in the kettle in the above embodiment, it may be adopted in another cooking device or a device for generating steam by boiling water with the same effect.

Further, in the above embodiment, the notification device 10 is provided on the top of the lid 2 in a state where the impeller 14 is horizontal. However, the notification device 10 is provided in other places of the lid 2 or in the container body. May be provided vertically or diagonally. As described above, since the location where the notification device 10 is provided is flexible, it is easy to provide the location where it is easy to use, avoiding the location where it is inconvenient to use.

The cover 16 may be made of glass, brass, or earthenware in addition to copper. By changing the materials of the cover 16 and the balls 22 or changing the number of the convex portions 23, various sounds can be generated and the taste of the user can be satisfied. Further, if the cover 16 is made of transparent glass, the rotation of the impeller 14 can be seen, which can entertain the user visually. At that time, the impeller 14 is colored or patterned. If you do, you can make it more effective.

The sounding body may be configured as follows. For example, a rotating shaft that rotates together with the impeller 14 is provided as an extension, a striking member similar to the ball 22 is provided on the rotating shaft, and the striking member collides with the rotating shaft around the rotating shaft as the rotating shaft rotates. May be provided. Further, as shown in FIG. 4, if a doll or the like is attached to the rotary shaft, the rotation can entertain the user visually. In FIG. 4, 100 is a doll, 110 is a rotating shaft, 122 is a hitting member, and 123 is a hit member.

Further, the ejection hole 11 may have a shape having a peripheral wall 11a as shown in FIGS. 5 is a vertical sectional view, and FIG. 6 is a view on arrow VI of FIG. The peripheral wall 11a is adapted to eject steam toward the rotation direction side of the impeller 14. According to this, since the steam is rectified and ejected, the impeller 14 is effectively rotated by the steam, the strength and weakness of the sound by the sounding body becomes clearer, and the boiling water state can be clearly known. You can

[Effect of the device]

 As described above, according to the boiling water state notification device 10 of the present invention, the impeller 14 is rotated by the steam ejected from the ejection hole 11, and the ball 22 which is rotated accordingly is collided with the convex portion 23. Since the sound is generated, it is possible to know whether the boiling water state in the kettle, that is, the boiling state is the initial state or the most violent state, depending on the strength of the sound.

Further, since the ball 22 is swingably attached to the impeller 14 via the ring 21, it is prevented that the rotation of the impeller 14 is hindered by the ball 22 colliding with the convex portion 23. it can.

Since the impeller 14 does not necessarily have to be installed horizontally, the location where the notification device 10 is installed is flexible. Therefore, it can be installed in an easy-to-use place, avoiding a place where it is inconvenient to use, and the convenience for the user can be improved.

By changing the materials of the cover 16 and the balls 22 or changing the number of the convex portions 23, various sounds can be generated and the taste of the user can be satisfied. If the cover 16 is made transparent and the impeller 14 is colored or patterned, the rotation of the impeller 14 can effectively entertain the visual sense of the user.
