Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a whistle kettle that indicates when the water in the kettle is boiling.

(Conventional technology) A whistling kettle that whistles when water boils,
Utility Model Publication No. 57-44900 or Utility Model Publication No. 63-153926
As disclosed in the above publication, a reed plate is attached to the lid of the sprue, and when the steam inside the kettle body is released into the atmosphere through the sprue, the kettle is hit against this reed plate to make a whistle sound.

(Problem to be solved by the present invention) In conventional kettles, either a lead plate is arranged in a straight path passing through the sprue inside the kettle body, or this steam path is once bent laterally, and a lead plate is installed in the bent steam path. A lead plate is arranged. In any case,
Since water droplets generated from the strong steam flow come into contact with the inner wall of the lid to which the reed plate is attached and the reed plate, the water droplets accumulate on the reed plate portion, eventually making it impossible to move the reed plate and causing the whistle to no longer sound. Therefore, it is necessary to disassemble the mounting part of the lead plate and remove water droplets.
It must be dried to allow the reed plate to vibrate again.

Repeating such operations makes using the whistle kettle cumbersome, and eventually the kettle ends up being used without the whistle blowing.

Therefore, the present invention aims to solve the problems of the prior art described above.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention basically divides the hollow part of the lid into a suction chamber, a whistle chamber where a reed plate is arranged, and an exhaust chamber. Technical means are used to arrange the passages between the rooms so that they are not located on the same line.

Preferably, the suction preparatory chamber having a plurality of suction chambers, and more preferably the whistle chamber, are opened to the atmosphere.

A suction chamber, a whistle chamber, and an exhaust chamber are arranged side by side in the horizontal direction.

(Function) The steam inside the kettle body first enters the suction chamber, where it cools down and removes excess moisture, ensuring vibration of the reed plate without directly attaching excess water droplets to the reed plate.

(Example) In the example shown in Fig. 1, a kettle body 2 of a whistling kettle 1 has a lid 3 removably attached to its upper opening, and a hollow spout 4 is fixed to the spout hole of the body 2 by caulking so that it extends obliquely upward from the side of the spout. A dish-shaped whistle holder 5 is fixed to fit onto a core metal fixed to the side wall of the spout 4. The whistle holder 5 is
It has a slit portion 6, and a flute cover 7 is attached to the slit portion 6.
One end of the pin 8 is pivotally mounted so as to be rotatable.
A square-shaped leaf spring 9 is placed in the hollow of the whistle holder 5, and one end of the leaf spring 9 is fixed to the side wall of the gate 4 of the hollow with a screw. A concave semicircular groove or recess is provided in the rising part of the leaf spring 9, and the semicircular protrusion 1 of the whistle cover 7 is inserted into this recess.
0 is made engageable with the upper end opening edge of the sprue 4 and the flute cover 7
The flute cover is adjusted from left to right and from front to back.
When the finger is put on the finger piece 11 and pressed in the direction of the arrow, the protrusion 10 pushes the leaf spring 9, and the flute cover 7 rotates around the pin 8 against the biasing force of the leaf spring 9, and the protrusion 1
When 0 passes over the line where the pin 8 and the leaf spring 9 contact each other (to the left in the figure), the flute cover 7 opens the sprue 4.
When the finger is pushed in the opposite direction, the force of the leaf spring 9 exceeds the contact line, and the flute cover 7 automatically closes the sprue 4 in a pressing state.

The flute lid 7 is shaped like a half-egg and has a first opening extending between the opposing side walls in the hollow part of the opening on the lower surface and partitioning the hollow part.
A partition wall 12 and a second partition wall 13 are provided. A screw receiver 14 having a circular cross section is provided integrally with the flute lid 7 at the center of the second partition wall 13. A plurality of lead plates 39, 3 with different tones fix an L-shaped mounting plate 16 that contacts the bottom wall, side wall, and step portion 15 of the second partition wall 13.
9', 39''.The mounting plate 16 divides the hollow part into an exhaust chamber 17 and a whistle chamber 18.A seat plate 19 is fixed to the opening of the whistle lid 7 at its center with screws.Installation The plate 16 is closely supported by the stepped portion of the screw receiver 14 by the pipe 20 that comes into contact with the seat plate 19.
Passages 21 and 22 are created by shifting the passages 21 and 22 between the partition wall 12 and the seat plate 19 and between the seat plate 19 and the L portion of the mounting plate 16 in a staggered manner, thereby forming three suction chambers 23 and 24 that communicate with each other. , 25. Note that the passage 21 has a larger hole than the passage 22. Further, the space at the top of the suction chamber is made higher than the height of the mounting plate 16 so as to create a spiral, and is used as a steam storage area. First suction chamber 2
3 communicates with the sprue 4 through the small hole 26, and the flute chamber 1
Reference numeral 8 also serves as a drainage channel for water droplets discharged to the atmosphere through a small hole 27 smaller than the passage 22. Exhaust chamber 17
is opened to the atmosphere through a plurality of holes 28.

FIG. 2 shows another whistle lid 29. This flute lid chamber 29
a pair of spaced apart bulkheads 30 extending between opposing sidewalls;
31 divides the inside of the whistle lid 29 into three suction chambers. A seat plate 33 is fixed to the opening of the whistle lid 29 in a stepped recessed part of the opening with pressure. A ∧-shaped plate 40 having reed plates 39' and 39'' on the inclined wall is placed in the chamber between the two bulkheads 30 and 31, with its edges brought into close contact with the side wall of the flute lid 29 and the seat plate 33, and inserted into the flute lid 29. , a first chamber 34, a second chamber 35, a third chamber 36, a fourth chamber 37, and a fifth chamber 38.The first and second chambers form suction chambers 34, 35. , the third chamber 36 serves as a whistle chamber, the fourth chamber 37 serves as an exhaust chamber, and the fifth chamber 38 serves as a preliminary chamber.The reed plate 39 is fixed to the hole in the inclined wall of the plate 40. The inclination promotes the flow of water droplets attached to the lead plate 39.

The first chamber 34 communicates with the sprue 4 through a small hole 41, and the first chamber 34 and the second chamber 35 are connected to each other through a plurality of small holes 42 formed in the first partition wall 30. communicate. The holes 41, 42, and 43 are arranged at different positions. The small hole 43 of the plate 40 provided with the lead plate 39 connects the second and third chambers 35 and 36.
The third chamber 36, which serves as a whistle chamber, communicates with the fourth chamber 37, which serves as an exhaust chamber, via a reed plate 39.
is exposed to the atmosphere through the small hole 44. Separately from this, a whistle chamber 36 can freely communicate with the atmosphere through a pair of small holes 45, 45' between the seat plate 33, the plate 40, and the front wall of the whistle lid 29. Note that the inner walls of the suction chambers 34 and 35 of the suction chambers 23 and 24 in the previous example may be provided with a rib portion of an uneven wall having a large surface area to absorb water droplets from the steam flow.

In the example shown in FIG. 3, the lid 3 is fitted into the opening of the kettle body 2, the sprue opening is closed, and the lid 3 is fitted into the opening of the kettle body 2.
The whistle lid 7 shown in FIG. 1 and the whistle lid 7', which is a knob with the finger pieces 11 and pin 8 removed, are fixed, and the same components are given the same reference numerals and the explanation thereof will be omitted. .

Next, we will explain the function of the whistling kettle. When the water in the kettle body 2 boils, a stream of steam enters the first chambers 23, 34 through the small holes 26, 41;
Next, it enters the suction chambers of the second and third chambers 24, 25, and 35. This inflow path changes the direction of the steam flow for each chamber, lowers the temperature, weakens the strength of the flow, reduces moisture in the steam flow, leaves water droplets on the inner wall of each suction chamber, and flows to the reed plate 39. Reduces water droplet adhesion. The steam flow enters the whistle chambers 18, 36 and flows into the exhaust chambers 17, 37 while vibrating the reed plate 39 and making a sound, but is eventually released into the atmosphere from the small holes 28, 44. Further, since the seat plates 19 and 33 are oblique to the horizontal plane, water droplets adhering to the inner wall of the suction chamber during the inflow channel flow from the side walls to the seat plate and are drained through the small holes 27 and 45. This reduces adhesion of water droplets to the lead plate 39 and promotes drainage.

(Effects) In the present invention, the steam flow sequentially flows into the suction chamber, the whistle chamber, and the exhaust chamber, and flows through the steam flow passage between each chamber or the passage that is not located on the same line. Excess water droplets reduce moisture in the steam flow along the side walls and seat plates of each chamber, and reduce water droplets on the lead plate by discharging accumulated water droplets. Therefore, the reed plate can always be made to whistle during boiling.
