Abstract

PURPOSE:To provide a gas range which can be turned down to an extremely weak heating power without causing flames to go out. CONSTITUTION:A kettle holder 3 is arranged around the periphery of a burner 1 and lifting devices 3a, 3c, 8 and 9 are provided to lift and lower the kettle holder 3. Thereby, the kettle holder 3 is raised to extend the distance between the burner 3 and the top of the kettle holder 3, so that a substantially weaker heating power can be obtained although the burner 1 remains unchanged with the same heating power at which flames does not go out.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cooking stove used by incorporating it into a system kitchen or the like.

[0002]

2. Description of the Related Art Conventionally, as a typical cooking device, a gas range having excellent heat power has been used, and various cooking operations such as simmering, baking, and frying are performed by this.

In such a gas stove, the heat power can be adjusted according to the contents of cooking, and the amount of gas can be adjusted by an operation switch to arbitrarily change from high heat to low heat.

However, since gas is originally used as a fuel source, it is usually 15 from the viewpoint of preventing extinction.
It cannot be reduced to below 0 kcal. Also,
Since the adjustment is made only by the operation switch, it is difficult to finely adjust the heat power at low heat.

For this reason, when it is necessary to simmer on a low heat for a long time, the gas fired power cannot be sufficiently narrowed down, and there is a problem that the bottom of the pot burns.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to obtain a gas range that does not cause the gas range to go out and can have a very weak heating power.

[0007]

Means for Solving the Problems The present inventor has completed the present invention by paying attention to the fact that an effect equivalent to that when the heating power is substantially weakened can be obtained by increasing the distance between the burner and the bottom of the pot. That is, the gas range of the present invention is characterized in that the Gotoku is arranged on the outer periphery of the burner portion and is provided with a lifting device for moving the Gotoku up and down.

Here, as an elevating device, Gotoku is a hollow cylindrical member capable of accommodating a burner inside, and a screw is engraved on the outer periphery thereof, and a main drive gear which engages with the screw to move the Gotoku up and down, It may be composed of a motor or the like for driving this.

[0009]

In the present invention, by increasing the Gotoku and increasing the distance from the burner with a burner fire power that does not extinguish, it is possible to obtain a substantially weaker fire power with the same fire power source. .

DESCRIPTION OF THE PREFERRED EMBODIMENTS The features of the present invention will be specifically described below with reference to the embodiments shown in the drawings.

FIG. 1 is a perspective view of a gas range showing an embodiment of the present invention.

The gas range A of this embodiment has four front, rear, left and right sides.
The burners 1 are provided at some places, and three of them are equipped with a normal Gotoku 2 which is detachably attached to the upper part of the burner 1 for supporting a pot or a frying pan. Further, the burner 1 on the front right side is provided with a movable gotoku 3 which can be moved up and down while a pot or the like is placed. In FIG. 1, 4 is a switch for operating the burner, and 5 is an elevating switch of the movable Gotoku 3.

FIG. 2 is a vertical sectional view of the movable gotoku shown in FIG. 1, and FIG. 3 is a perspective view of the movable gotoku.

Referring to FIG. 1, the movable Gotoku 3 has a hollow cylindrical main body 3a having a space for accommodating the burner 1 therein.
And a circular Gotoku 3b formed on the upper part of the cylindrical body 3a, and a male screw 3c is formed on the outer periphery of the cylindrical body 3a from the upper end to the lower end. Further, an air insertion hole 3d is formed on the peripheral surface of the cylindrical main body 3a. The cylindrical main body 3a is screwed onto an annular support member 7 attached to the opening of the top plate 6 and having an internal thread 7a formed on the inner peripheral surface thereof. Reference numeral 8 is a driving gear that meshes with the male screw 3c of the cylindrical body 3a to rotate the movable Gotoku 3, and a driving motor 9 is connected to the driving gear 8 and is further connected to the operation switch 5 shown in FIG. Further, the burner 1 is fixed on the support 10 so that the movable Gotoku 3 can move up and down without any trouble.

In the above structure, the movable gotoku 3 is lowered to the lowest position for use in normal cooking work. In this state, the distance S between the burner 1 and the pot bottom placed on the movable Gotoku is about the same as in the case of the normal Gotoku 2 shown in FIG.

When particularly weak heating power such as simmering for a long period of time is required, when the operation switch 5 is rotated to the right, the drive motor 9 moves and the driving gear 8 is rotationally driven, and the movable gotoku 3 rises. This rising height can be continuously changed according to the rotation speed of the movable Gotoku 3, and the burner 1 shown in FIG.
By adjusting the distance S between the pot and the bottom of the pot, it is possible to obtain a low heat power. The movable Gotoku 3 is provided with a stopper (not shown) for preventing an excessive rise, and can prevent the pan from falling due to excessive rise.

By rotating the operation switch 5 counterclockwise, the drive motor 9 can be rotated in the reverse direction and the movable gotoku 3 can be lowered.

As described above, according to this embodiment, by raising the movable Gotoku 3 and separating the pot bottom and the burner 1 from each other, it is possible to obtain a substantially weaker heating power while maintaining a constant heating power source. Conventionally, it may have a weak fire power that may disappear.

In the above embodiment, a male screw 3c is formed on the outer circumference of the cylindrical main body 3a of the movable Gotoku 3, and the main gear 8 meshing with the male screw 3c is used as the movable Gotoku lifting device.
Of course, the structure is not limited to such a structure, and for example, a lifting device includes a plurality of legs extending downward from the upper surface of Gotoku and forming a rack in the axial direction of the outer periphery, and a pinion that meshes with the rack and works in conjunction with a drive motor. In addition, a plurality of legs extending downward from the bottom surface of Gotoku and forming threads on the outer periphery, a pinion that interlocks with the drive motor, and a rack that meshes with the pinion are formed on the lower surface and the inner periphery is An elevating device can be formed by forming an internal thread that meshes with the screw thread, and an annular transmission member that is positioned so as to rotate in the same plane. In these cases, Gotoku can be moved up and down without rotating. Furthermore, the cylinder that expands and contracts may be used to move up and down, or the gear may be manually rotated without providing a drive motor.

[0020]

According to the present invention, the following effects can be obtained.

(1) By moving the Gotoku up and down, the fire power can be finely adjusted, and a weak fire power without extinction, which could not be obtained in the past, can be obtained.

(2) By moving Gotoku up and down, it is possible to align the upper end levels of pots of different heights, which facilitates the work of a plurality of pots.
