Description

  The present invention relates to a knob with a safety whistle that is attached to a pan lid or the like and has high safety and emits a warning whistle by steam.

Traditionally, some high-end and highly airtight cooking utensils used steam to make a sound to notify boiling, and after boiling there was a whistle-plucking to reduce energy and cook energy-saving. . (Patent Document 1) states that “a hollow screw member having a through-hole on the front end surface and commonly explained on the surface side from the accompanying Taura side, and a cylindrical shape having a concave bottom portion screwed into the screw member. A pan lid comprising a main body having a gripping part integrally formed in the periphery and having a spout on the side wall of the bottom, and a plug-like operation member having a space in the main body that is rotatably and vertically inserted in the main body In the handle, an annular groove is formed in the inner periphery of the bottom portion of the cylindrical portion, and a whistle hole is formed in the center of the bottom plate, and an opening / closing member for the whistle hole is protruded inside the operation member. A knob with a horn for a pot lid, which is provided with a plurality of open ports that overlap with the jet nozzles in a lateral direction on a lower side wall of an operation member that fits in the box is disclosed. In addition, (Patent Document 2) states that “in order to prevent the occurrence of spilling, the steam pressure in the cooking space increases before the cooking space rises and the spillage occurs from the gap between the pan body and the lid. Cooking with a mechanism with a mechanism to prevent the occurrence of spilling from the gap between the pan body and the lid by discharging and lowering the pressure, and returning a part of the condensed water vapor to the cooking space "Pot" is disclosed.
However, the above conventional techniques have the following problems.
(1) Since the technique disclosed in (Patent Document 1) does not have a pressure regulating mechanism, there is a risk of spilling after boiling if the steam passage is closed, and cooling is performed with the steam passage closed. In such a case, the pressure inside the cooking utensil is lowered, so that it is difficult to remove the lid. In addition, when the airtightness of the pan, the weight of the lid, and the heat power adjustment of the heat source cannot be accommodated, water droplets scatter and the surrounding area becomes dirty, so it is necessary to move the lid to prevent it and there is a problem that it is not convenient ing.
(2) The technology disclosed in (Patent Document 2), when the internal pressure of the cooking utensils rises, the steam is discharged, so no spilling occurs, but the horn does not sound, so if it is not on the side, adjustment of heating The timing is not known, and there is a high possibility that energy is wasted. Moreover, since there is no pressure regulation function at the time of pressure reduction, when the internal pressure of a cooking base falls, it has the subject that it is difficult to remove a lid | cover.
In addition, the conventional sensor pick with a whistle has a problem that when the steam is directly or vertically removed, there is a risk of burns due to the heat exhausted from the steam in the opening and closing operation, and the hook type pick is difficult to design. Was. In order to solve these problems, the present inventor has eagerly studied, "Since the vapor passage can be opened by the weight of the lid simply by lifting the lid, the use in the wrong state without confusion between opening and closing is possible. Completed the invention of a knob with a horn such as a pan lid, which can prevent the accidental hand from touching the discharged steam by arranging the steam discharge part at the bottom of the knob and has excellent usability and safety. And obtained a patent (Patent Document 3).

Japanese Utility Model Publication No. 63-183924 Japanese Patent Laying-Open No. 2005-205136 JP 2008-86444 A

(1) The technique disclosed in (Patent Document 3) has a demand for improvement because there is a risk of burns due to steam when the steam passage is opened because the steam discharge port faces downward.
(2) There was a demand for a hook type pick that can be lifted easily, opened and closed easily, and can be used safely even by people with weak grip.

  The present invention solves the above-mentioned demand, and can be produced at a low cost with a simple design, with few parts, and a pressure regulating damper capable of adjusting the pressure inside the cooking utensil by informing boiling by the whistling sound generated during cooking. An object is to provide a built-in high-safety pick with a safety whistle.

In order to solve the above conventional problems, the knob with a safety whistle of the present invention has the following configuration.
The knob with a safety whistle according to claim 1 of the present invention includes: (a) a screw part having a through hole in the center; and the screw part screwed through a knob attachment hole of a lid and communicating with the through hole. A whistle base part having a whistle penetrating part, a warning whistle generating part consisting of a recess formed on the opposing surface of the screw part and the whistle base part, and (b) a notch for discharging steam at the lower end part A steam discharge cover that concentrically surrounds the whistle base, (c) a lower screwed portion that is screwed to an outer peripheral screwed portion of the whistle base, and a lower screwed portion A knob main body having a diameter-expanded portion continuously provided through the stepped portion, and a steam port formed in the stepped portion; (d) a peripheral wall; a top plate; and a lower portion of the peripheral wall. An inner lid having an engagement portion engaged with an inner lid fitting portion at the lower portion of the inner wall; (e) an upper lid peripheral wall; a bottom plate; and a lower portion of the upper lid peripheral wall before being formed Has a lid engaging portion engaged with the engaging groove of the upper portion of the inner wall of the knob body, the structure comprising a top lid, a with.
With this configuration, the following effects can be obtained.
(1) Since the steam passing through the inside of the knob diffuses inside the knob, the temperature of the steam is lowered, and further, the steam is discharged from the notch of the steam discharge cover along the upper surface of the pan lid. Compared to the conventional structure that ejects directly from the hood, the risk of burns can be greatly reduced and the safety is excellent.
(2) When boiling, a sound is generated from the horn generating section to notify the boiling, so that the heating power after boiling can be adjusted smoothly, and wasteful useless energy can be eliminated.
(3) Since the structure of the portion where the steam diffuses is a double wall, it is not hot even when the knob is lifted with bare hands, and safety can be improved.
(4) Since there is no vapor discharge hole on the top or side of the knob, hook-type knobs can be created regardless of the shape of the knob, and various designs can be accommodated.
(5) The boiled juice that enters the pick with steam flows from the bottom, and high-temperature steam diffuses inside the pick, so that bacteria are unlikely to occur and can be easily decomposed and cleaned inside when not used for a long time. And since it can be easily dried, it is excellent in hygiene.

Here, as a material of the screw part, the whistle base part, the knob main body, the steam discharge cover, and the inner lid, a synthetic resin or hard rubber having heat resistance and corrosion resistance is preferably used. The whistle penetrating part of the whistle base part is opened to the concave part, the peripheral wall is raised, and the top surface is formed on the positive surface of the flat opening / closing damper.
Further, the lower surface of the open / close damper is slidable and is sized so as to cover the entire sliding surface so that the pressure can be adjusted by being in close contact with the sliding surface of the whistle base.
The facing surfaces of the upper lid and the inner lid may be flat, but at least one of them has protrusions or ridges so as to form an air layer as a heat insulating layer in order to mitigate heat transfer from the inner lid to the upper lid. It may be provided.
The inner wall of the main body is formed in close contact with the peripheral wall of the inner lid. The inner wall may be formed of hard rubber. Thereby, it can prevent that the heat | fever of the vapor | steam ejected from the whistle penetration part of the whistle base part inside the inner wall transfers heat to the exterior of the knob.
The peripheral wall of the upper lid and the upper lid arrangement portion of the knob body are formed so that the upper lid is fitted inside the upper lid arrangement portion or covered from the upper lid (outside) of the upper lid arrangement portion so as to be in close contact with each other. This is to prevent high temperature steam from leaking from the gap between the upper lid placement portion of the knob body and the upper lid and causing an accident.

One or more notches are formed in the steam discharge cover. When multiple cutouts are formed, the emitted steam is diffused and the pressure is reduced, and the steam is released in many directions along the top of the pan lid, further reducing the risk of burns. Can do. In addition, by shifting the position of the notch and the position of the steam port of the knob body during assembly, the steam moving distance may be extended and the temperature may be lowered.
In addition, by forming a discharge port that protrudes in a U-shaped cross section in the outer peripheral direction of the lid at the peripheral edge of the notch of the steam discharge cover, the movement distance until steam is discharged is extended, so it is safer Can also be increased. The discharge port may be formed by extending the peripheral edge of the notch, or may be formed separately.

  As the horn generating portion, various devices that generate a horn by the passage of steam may be used, or the horn may be generated by providing a space on the opposing surfaces of the screw portion and the whistle base portion.

With this configuration, the following actions are obtained in addition to the actions obtained in the first aspect.
(1) By operating the open / close damper with the open / close lever, the whistle penetrating portion can be easily opened / closed, so that whether the lid is airtight or not can be selected according to the cooking method.
(2) If the heat source is turned off when the open / close damper is closed, the cooking utensil is depressurized, and the sliding part between the open / close damper and the whistle base is automatically adsorbed to maintain airtightness and prevent cooling. In addition, when releasing the airtight state, such as when the lid is opened, it can be easily opened without opening the open / close damper, and the pressure difference is eliminated.
(3) Since the open / close damper can be moved up and down, the open / close damper is lifted before the pan lid is lifted by the steam pressure, allowing excess steam to escape, so that the pressure inside the cooking utensil can be kept constant. Can be prevented from being blown out and scattered from the lid, and the release of useless energy can be suppressed.
(4) When strong airtightness is ensured due to the structure of the pan, the weight of the lid, etc., the closed state can be easily locked only by moving the fixing lever to the fixing position.

As the material of the rotary shaft and the open / close damper, a metal such as a synthetic resin or stainless steel having excellent heat resistance and corrosion resistance, or a combination thereof, as well as a screw part, a whistle base part, a knob main body, and a steam discharge cover are used.

The assembly of the safety whistle knob 1 of the first embodiment configured as described above will be described with reference to FIG.
The screw portion 2 is inserted into the knob mounting hole B of the lid portion A from below, and is screwed into the whistle base portion 3 via the sealing portion 12 from above and fixed to the lid portion.
Next, the steam discharge cover 4 is picked so as to cover the whistle base 3, and the lower threaded portion 5 a of the main body 5 is screwed into the outer peripheral threaded portion 3 b of the whistle base 3, and the steam discharge cover is covered by the pick main body 5. 4 is fixed from above.
Next, the shaft insertion portion 7d of the inner lid 7, the upper lid rotation shaft mounting portion 8c of the upper lid 8, and the rotation shaft insertion portion 9a of the opening / closing lever 9 are overlapped, and the rotation shaft 10 is inserted and connected from above. After the connection, the spring 11 is inserted into the rotating shaft 10, and then the rotating shaft 10 is inserted into the rotating shaft insertion hole 6 b of the opening / closing damper 6.

At this time, the movable damper 6 is not limited to a coil spring such as the spring 11 but may be a leaf spring or the like. In addition, depending on the weight of the lid A, the degree of adjustment of the vapor pressure inside the cooking utensil can be easily controlled by adjusting the strength of the spring 11.
In addition, even when the pressure blows down and boiled juice flows out of the steam discharge cover and flows down the surface of the lid A together with the dirt on the surface of the lid A, the lid A is provided with the receiving portion C. It can collect in the receiving part C, and can prevent that broth etc. return in a cooking appliance. As a method for preventing boiled broth from returning into the cooking utensil when there is no receiving portion C, a method using a lid A larger than the diameter of the cooking utensil, a lid A so that the broth falls around the cooking utensil. There is a method of providing a fence around

Next, the opening and closing of the safety whip knob 1 and the flow of steam will be described with reference to FIGS.
A cooking utensil such as a pan covered with the lid A is heated to boiling. At this time, by setting the open / close lever 9 to the open side of the display portion 8d, the damper hole 6a of the open / close damper 6 and the whistle penetrating portion 3a of the whistle base portion 3 are overlapped, and the steam passage is in a penetrating state to the outside. . Then, when the steam 13 passes through the first steam passage 2d and the through hole 2a and passes the horn generating portion 14 formed by the upper surface recess 2e and the inner wall of the whistle base 3, the horn is generated by the steam pressure. Next, the steam 13 passing through the whistle penetrating part 3a and the damper hole 6a hits the top plate 7c of the inner lid 7, diffuses in the second steam passage 7e, passes through the third steam passage 4c from the steam port 5c, and is picked. Is discharged along the upper surface of the lid A from the cutout 4a of the lower steam discharge cover 4 away from the position having the position.
At this time, considering the balance with the lid, the volume of the second steam passage 7e may be 30 to 80 mm in diameter, 20 to 80 mm in height, and 14 to 400 cc in volume, but is not limited thereto. .
Further, by forming a discharge port protruding in a U-shaped cross section in the outer peripheral direction of the lid A at the peripheral portion 4d of the notch 4a of the steam discharge cover 4, the moving distance until the steam 13 is discharged is increased. Since it extends, safety can be improved. The discharge port may be formed by extending the peripheral edge portion 4d of the notch, or a separately formed one may be attached.

After the horn has sounded, no strong heating power is required. Therefore, the heating of the heating cooker is weakened, and the open / close lever 9 is set to the closed side of the display portion 8d, thereby sliding the flat plate 6d of the open / close damper 6 by the flat plate 6d. The passage of steam is blocked and the horn stops (see FIG. 5 (a)). When heating is continued in this state and the vapor pressure rises, the vapor pressure is greater than the force with which the spring 11 presses the open / close damper 6, so that the open / close damper 6 rises. Therefore, the internal pressure of the cooking utensil is kept constant by releasing steam a little before the lid A is lifted, and serves as a safety valve.
If it is not desired to escape the steam, the lifting lever 6c of the opening / closing damper 6 can be easily picked up and fixed to the fixing portion 5i of the main body 5 as necessary, so that the floating can be prevented easily. Note that the fixing lever 6c and the fixing portion 5i need not be provided if not necessary.
When heating is stopped in the closed state, the inside of the cooking utensil is depressurized, and the flat plate 6d of the open / close damper 6 is adsorbed to the sliding surface 3c of the whistle penetrating part 3a of the whistle base 3 to block outside air. In addition, if the pressure difference between the inside and outside of the cooking utensil occurs due to the reduced pressure state and the lid cannot be opened, the pressure difference can be eliminated by adjusting the open / close lever 9 to the open side of the display portion 8d. Can be opened.

Since the safety whistle knob 1 according to the first embodiment is configured as described above, it has the following effects.
(1) When the open / close lever is closed, the lever does not move and fix in the horizontal direction for opening and closing like a general sensor knob, but moves up and down to automatically adjust the pressure. In the case of a pan with good heat conductivity in an airtight structure in which the lid lifts due to steam pressure and blown down, etc. even if the heat power is reduced to the minimum weak or hot fire, even if there is no steam venting In this case, it is possible to prevent the blown-down and water droplets from being scattered, and further, no extra labor is required for cleaning the scattered dirt.
(2) Since the weight of the lid is related to the airtight structure inside the knob, before the lid lifts, the opening / closing damper that has the pressure adjustment function inside the knob and the function of the opening / closing lever escapes the steam slightly. By adjusting the pressure and keeping the internal pressure constant, it is possible to prevent spilling from the lid and unpleasant scattering, and it can be used comfortably and wasteful energy release can be suppressed.
(3) The pressure can be controlled only by the natural gravity of the open / close damper, but in the case of an extremely heavy and extremely heavy lid, the pressure can be controlled according to the weight of the lid simply by adding a little spring strength. .
(4) If you want strong airtightness due to the shape of the pan and the weight of the lid, with the open / close lever closed, with the sliding surface of the whistle base and the open / close damper in close contact, By fixing the fixing lever to the fixing portion of the main body, it is possible to prevent the open / close damper from lifting and to obtain airtightness.
The lifting of the open / close damper can be fixed.
(5) Normally, when installing a pressure regulating valve, when the lid and knob body are fixed, and using a piston type pressure regulating valve or shape memory alloy like a pressure cooker or rice cooker, it is discharged upward Many of them are used in fixed models, so if the shape, lid thickness, and weight are different, there is a disadvantage that parts that are appropriate for each model are required and the cost is increased. Detachable assembly type for excellent versatility.
(6) When the heat source is stopped, the inside of the cooking utensil is decompressed and the open / close damper is in a closed state, and the sliding surfaces of the open / close damper and the whistle base portion are automatically adsorbed to maintain an airtight state. Therefore, the backflow of air can be prevented, it can prevent becoming easy to cool, and the remaining heat can be utilized.
(7) When opening the lid in a state where the cooking utensil is decompressed, the open / close damper can be slid by simply moving the open / close lever in the opening direction so that the whistle penetrating portion can communicate with the outside air, thereby eliminating the pressure difference. It can be opened easily.
(8) Since the second steam passage through which the steam diffuses is a double wall, it is difficult to get hot, and the lid can be lifted with a bare hand, which is excellent in safety.
(9) The boiled juice that enters the inside of the knob together with the steam has a structure that flows out from the cutout of the steam discharge cover. During use, high-temperature steam is always diffused, so that bacteria are not generated and it is hygienic. Also excellent.
(10) Since the structure can be easily decomposed, it can be decomposed and dried when not used for a long time.
(11) It is possible to realize energy saving without destroying the water film due to airtightness by the water seal.
(12) In particular, when cooking is performed using a modern gas stove or IH stove, where it is difficult to control low heat or hot fire, unpleasant dirt due to scattering can be prevented.

The point 20 with the safety whistle of the second embodiment is different from the first embodiment in that the opening / closing damper 6, the shaft insertion portion 7d of the inner lid 7, the upper lid rotating shaft insertion portion 8c of the upper lid 8, the opening / closing lever 9, and the rotation shaft 10 and the spring 11 is not provided.
As shown in FIG. 5, the screw part 2, the whistle base part 3, the steam discharge cover 4, and the knob body 5 are assembled in the same manner as in the first embodiment, and the inner lid 7 ′ without the shaft insertion part is inside the knob body 5. The upper lid engaging portion 8e is engaged with the inner lid fitting portion 5g via the engaging portion 7b, and the upper lid engaging portion 8e without the upper lid rotating shaft insertion portion is gripped on the upper surface side of the inner lid 7 '. Engage with the upper engaging portion 5h.

As described above, the safety whip knob 20 of the second embodiment is configured, and thus has the following operation in addition to the operation of the first embodiment.
(1) The steam is once diffused inside the knob with the safety whistle and discharged in multiple directions along the top of the pan lid from the notches of the steam discharge cover. There is less risk of burns compared to direct jetting.
(2) Since the diffusing room has a double wall structure, even when the lid is lifted by holding a pick with bare hands, it is difficult to become hot and the safety is greatly improved.
(3) Since there is no steam outlet in the upward or sideways direction, it is possible to pick with a hook-type whistle.
(4) Since the structure is simpler than the knob with the safety whistle of the first embodiment, it can be easily disassembled and is excellent in maintainability.

(Embodiment 3)
FIG. 8 is a side view of the knob with a safety whistle according to the third embodiment.
Components similar to those of the safety whistle knob in Embodiment 1 are denoted by the same reference numerals, and description thereof is omitted.
30 is a knob with a safety whistle in Embodiment 3, and 31 is a hook formed on the upper surface of the knob.
The third embodiment includes the hook 31 in the knob with the safety whistle of the first or second embodiment. The hook 31 may be formed directly on the upper lid 8 or the knob body 5, but the hook 31 may be bonded by providing a joint on the upper lid 8 or the knob body 5.
When the opening / closing lever 9 is provided, the hook 31 may be formed in any way as long as it does not hinder the operation of the opening / closing lever 9.
As described above, the safety whip knob 30 of the third embodiment is configured, and thus has the following operation in addition to the operation of the first or second embodiment.
(1) Since the hook can be lifted through a finger or a string, a person with weak gripping force can lift the lid A safely and easily.

  The present invention can be produced at a low cost with a simple design, fewer parts, high safety with a built-in pressure regulating damper that can notify boiling by whistling by steam generated during cooking and adjust the pressure inside the cooking utensil A whistle-pick can be provided.
