As shown in FIG. 1, the present invention relates to a gas stove thermal protector used in a portable, domestic or commercial gas stove.

It has a flame inlet 11 through which the flame of the gas stove flows in the lower end, and has an opening 12 in the upper end, and has a slope 13 having a wider cross-sectional area from the lower side to the upper side, and the lower end of the slope 13 An inner film 10 having a vertical surface 15 which is bent inward and vertically supported by the pedestal base 1 of the stove; And

The inner film is bent from the top of the inner membrane 10 to the outer membrane 20 which is vertically supported on the pedestal base (1) of the stove;

On the lower side surfaces of the inner membrane 10 and the outer membrane 20, a fixture 30 having a shape and a number corresponding to the gas stove support piece 2 is formed, respectively.

The inclined surface 13 of the inner membrane 10 is characterized in that a plurality of support protrusions 14 are provided in a concentric shape.

In general, a thin metal plate material is coated with paint or the like and has a rounded shape so as to be easily mounted on the top of the stove.

The inner membrane 10 is located inside the gas stove thermal protector of the present invention and has a generally rounded shape and has a flame inlet 11 through which a flame of the gas stove is introduced at the lower end thereof, and an opening 12 at the upper end thereof. It is a structure that is open up and down. In addition, by having a slope 13 wider cross-sectional area from the lower portion to the upper portion such that the pot is placed on the slope (13). Here, since the slope 13 is provided with a plurality of support protrusions 14 in the shape of concentric circles, it is possible to freely raise and cook pots of various sizes. Of course, on the top, you can put a wide plate or grill.

In addition, since the slope 13 is formed in the form of a plurality of convex projections 14 in an inclined shape, when the pot is placed on the slope 13 is very stable. This is because, in the case of a general gas stove support piece, the pot is not shaped to surround the pot by simply placing the pot on the upper part of the support piece, so the pot may move up, down, left, and right. However, in the case of the present invention, since the slope 13 is tightly wrapped around the pot, there is no fear of moving up, down, left and right, and thus it is possible to cook very stably.

The lower end of the slope 13 has a vertical surface 15 which is bent inward and vertically supported by the pedestal base 1 of the stove. The vertical surface 15 is formed in a cylindrical shape to surround the fire hole 3 of the stove as a whole and serves to transfer the load of the pot or plate placed on the slope 13 to the pedestal base 1 of the stove. In other words, it is a supporting role. Therefore, it is preferable that the vertical surface 15 meets perpendicularly to the pedestal base 1 rather than the slope 13.

In addition, the vertical surface 15 is preferably lower than the height of the fire hole 3 of the stove. The height difference between the pothole 3 and the pot may vary depending on the size of the pot, and the larger the pot, the greater the distance from the pothole 3, so that the height of the pothole 3 is slightly higher than that of the vertical plane 15. Because it is good.

In addition, it is preferable that the inclination of the said slope 13 is 10-15 degrees. If the slope of the slope (13) is urgent, it is not a problem if the pot is small and placed on the bottom of the slope, but if the pot is large, the heat is required even though the heat is required. The difference in the distance between the pan and the pan becomes large, making it difficult to heat the pan efficiently. Therefore, it is good to make the slope of the slope 13 low so that even if the pot size is large, the distance from the fire hole 3 is close, so that heat can be applied effectively.

In addition, it is preferable that a reflection paint (not shown) is applied to the inside of the slope 13 or the vertical surface 15. In order to improve the efficiency of the stove, there is a method of improving the thermal efficiency of the stove itself, but there is also a method of concentrating the flame generated in the stove.

Since the flame generated from the stove is formed on the inside of the slope 13 and the vertical surface 15 described above, the pot to raise the heat to heat the slope 13 and the vertical surface 15 to the top of the slope 13 In order to concentrate on the back, there is a method of applying a reflective paint on the inside of the slope 13 or the vertical surface 15. This is a good way to increase the thermal efficiency by simple operation.

Here, the reflective paint means a paint having a reflective effect such as silver, and preferably, a paint having an insuladd powder mixed in the paint. When the paint is applied by mixing the insulation with a paint, a ceramic film is formed after the coating so that it can withstand the heat of 1800 ° C.

It was developed by NASA in the United States and is inexpensive, used as a heat insulator and reflecting heat. The insulation is ceramic microscopic hollow spheres, mainly composed of alumino silicate. Hollow means hollow inside like a ping-pong ball. Insulated is the only ceramic-based material in the state of being empty, but the insulation is made of a ceramic film (insulation layer) on the coating layer on the painted surface. Exert.

When the ceramic film is formed on the inside of the slope 13 or the vertical surface 15 of the gas stove thermal protector of the present invention using the insulation, the efficiency of the thermal power can be increased by about 30%.

The outer membrane 20 is located on the outside of the gas stove thermal protector of the present invention is bent from the upper side of the inner membrane 10 to the outside to have a generally rounded shape, the lower end vertically to the pedestal base (1) of the stove You will come across.

The gas stove thermal protector of the present invention is composed of a thin metal material as a whole to reduce the unit cost, so it is difficult to support a heavy pot, such as lacking the support force only by the above-described inner membrane 10, the inner membrane 10 to compensate for the insufficient bearing capacity The outer membrane is bent to the outside from the top of the bottom) is provided with an outer membrane 20 which is in contact with the pedestal base (1) of the stove vertically. The outer membrane 20 also serves to transfer the load of the pot or the like to the pedestal base 1, so that the outer membrane 20 is in direct contact with the pedestal base 1.

Here, the lower side surfaces of the inner membrane 10 and the outer membrane 20 are formed with fixtures 30 of the shape and number corresponding to the gas stove support pieces 2, respectively. Since the stove is essentially provided with a gas stove support piece (2), in order to use the present invention in addition to the stove, it is necessary to have a shape that can be fitted to the gas stove support piece (2).

In addition, when the gas stove thermal protector described above is mounted on the gas stove, it is difficult to visually check whether the flames of the gas stove are alive. Therefore, the inner membrane 10 and the outer membrane 20 It is preferable to further provide a flame check opening 40 that can observe the flame of the stove.

In addition, the gas stove thermal protector of the present invention is a part that the user should be in direct contact in the process of use or clean up after use, and heat is applied to it, so care must be given to the contact. To this end, a heat-sensitive tape (not shown) or a thermochromic pigment (not shown) is attached to the upper surface of the slope 13 and the outer film 20 so that the color may vary depending on a predetermined temperature.

In the present invention, the heat-sensitive tape or thermochromic pigment is a temperature state of the container by using an optical property that exhibits a reversible color change (thermal discoloration) that appears at a predetermined temperature when the gas stove thermal protector is heated or cooled. Is to be displayed on the outside, so that the temperature of the gas stove thermal protector can be visually identified and handled with confidence.

Herein, the thermochromic pigment is changed from achromatic to red when heated at around 45 ° C., which is a temperature at which a person feels hot, and is preferably configured to be reduced to the original achromatic color when cooled. In addition, the heat-sensitive tape is a method using a transfer paper printed with the thermochromic pigment as a tape. Since this is a known technique, a detailed description thereof will be omitted.

In addition, it is preferable that a rubber (not shown) or a magnet (not shown) is attached to the lower surface of the vertical surface 15 or the outer membrane 20.

Gas stove thermal protector of the present invention is mounted in such a way as to be mounted on the top of the stove it is preferable to have a device for fixing it. Therefore, a rubber stove protector is attached to the bottom of the vertical surface 15 or the outer membrane 20 to prevent slippage, or a gas stove thermal protector is attached to and fixed to the pedestal base 1 of a steel stove by attaching a magnet. It is desirable to be able to.
