Therefore, the gas stove thermal protection device 100 can be modified in other forms.

As shown in FIG. 1, the gas range thermal protection device 100 includes a main body 10, a seating part 20, and a support part 30. In addition, the gas range thermal protection device 100 may further include other components as necessary.

The main body 10 has a circular shape and may be installed in the gas range. The main body 10 includes a flame opening 101, an inclined surface 103, a connecting surface 104, first air inflow holes 105, second air inflow holes 107, and a first confirmation hole 109. ) May be included.

Fireball 101 may be located below the body portion (10). Fireball 101 may have a circular shape. Fireball 101 may pass the flame of the gas range. The inclined surface 103 may be formed radially around the fireball 101. That is, the lower end cross-sectional area of the inclined surface 103 may be smaller than the upper end cross-sectional area of the inclined surface 103. The inclined surface 103 may be symmetrically formed with respect to the center of the fireball 101.

The inclined surface 103 may include a first slope 1031 and a second slope 1033. The first slope 1031 and the second slope 1033 may be formed in a circular shape along the circumference of the main body 10. The first slope 1031 and the second slope 1033 may protrude to the inside of the main body 10. The first slope 1031 may be located between the first air inflow holes 105 and the second air inflow holes 107. The second slope 1033 may be located above the second air inflow holes 107.

The connection surface 104 may extend in the z-axis direction. The connection surface 104 may be located surrounding the flame of the gas range. One side of the connection surface 104 may be connected to the flame port 101, the other side of the connection surface 104 may be connected to the inclined surface 103. Since the connection surface 104 may block the outside wind, the flame of the gas range may be prevented or extinguished.

The first air inlet holes 105 may be located on the inclined surface 103. The first air inlet holes 105 may be located on the same circumference of each other along the circumference of the body portion 10. The first air inflow holes 105 may be located through the inclined surface 103. The outside air of the main body 10 may move into the main body 10 through the first air inflow holes 105. The air introduced into the main body 10 may increase the flame efficiency of the gas range by inducing complete combustion of the gas. Air passing through the first air inlet holes 105 may induce combustion of an inner flame of the flame.

The second air inlet holes 107 may be located on the inclined surface 103. The second air inlet holes 107 may be located on the same circumference of each other along the circumference of the body portion 10. The second air inlet holes 107 may be located above the first air inlet holes 105. The second air inlet holes 107 may be located through the inclined surface 103. The outside air of the main body 10 may move to the inside of the main body 10 through the second air inlet holes 107 to induce combustion of the outer flame of the flame.

The first air inlet holes 105 and the second air inlet holes 107 may be spaced apart from each other at predetermined intervals in the direction in which the inclined surface 103 extends around the flame opening 101. Air flows through the air inlet holes 105 and 107 radially in the same line and moves to the inside of the main body 10 constantly in a laminar flow state to react with the gas relatively quickly to shorten the combustion time. have.

The gas range thermal power protection device 100 may introduce external air into the interior through the first air inflow holes 105 and the second air inflow holes 107 to induce combustion of flame and flame of flames, respectively. have. Therefore, since the gas range thermal protection device 100 can completely burn the flame, it is possible to reduce the cost of butane gas by increasing the use efficiency of butane gas.

On the other hand, in the prior art, it is difficult to introduce a sufficient amount of air into the flame of the gas range, so that butane gas cannot be completely burned, and thus, the thermal power may be weakened over time or the butane gas efficiency of the gas range may be low. There may be a risk of overdose.

The diameter of the first air inlet holes 105 may be 0.7cm to 0.8cm. The diameters of the second air inlet holes 107 may be 0.5 cm to 0.6 cm. The diameters of the first air inlet holes 105 may be larger than the diameters of the second air inlet holes 107. In flame combustion, gas and air are primarily combusted in flame, and diffusion combustion is performed from external flame to remaining gas and air, so that flame efficiency may vary according to combustion reaction of flame.

Therefore, since combustion reaction of flame resistance is important, the air passing through the first air inlet holes 105 by the diameter of the first air inlet holes 105 is larger than the second air inlet holes 107. It is desirable to lead the combustion of flame resistant to complete combustion. In addition, when the diameters of the first air inlet holes 105 are larger than the diameters of the second air inlet holes 107, the first air inlet holes 105 may directly introduce oxygen into the flame hole 101. Therefore, the ignition efficiency can be increased. That is, the gas range thermal protection device 100 may circulate air to the inside and outside of the main body unit 10 while protecting the thermal power from the outside wind as the primary, thereby increasing the butane gas efficiency of the gas range.

One side of the first seating surface 201 may be connected to the second seating surface 203a, and the other side of the first seating surface 201 may be connected to the second seating surface 203b.

Heights of the second seating surfaces 203a and 203b from the upper surface 102 may be the same. The height of the first seating surface 201 from the upper surface 102 may be greater than the height of the second seating surfaces 203a and 203b. In this case, in comparison with the case where the first seating surface 201 and the second seating surfaces 203a and 203b have the same height, separation of the cooking vessel P from the seating portion 20 may be prevented. Can be.

For example, when one side of the cooking vessel P is inclined by an external force while the cooking vessel P is seated on the first seating surface 201, the second seating surfaces 203a and 203b are cooked. The lower surface of the container P can be further supported. Thus, the phenomenon of spilling of the contents inside the cooking vessel P can be prevented.

The main body 10 is inclined with respect to the upper surface 102 and the support 30 is positioned in the z-axis direction so that the main body 10 may include a space between the main body 10 and the support 30. The lower length of the separation space, that is, the separation distance between the connection surface 104 and the support part 30 may be about 5 cm.

When the support part 30 is in contact with the external wind, the strong external wind may be dispersed in the weak wind. The distributed weak wind may pass through the space between the body part 10 and the support part 30 and move into the body part 10 as air necessary for combustion through the air inlet holes 105 and 107. That is, the strong external wind is blocked by contacting the support 30, the main body 10, and the inclined surface 103, is dispersed into the weak wind flows into the main body 10 and converted into air for combustion to convert the gas May lead to complete combustion. Therefore, the gas range thermal protection device 100 may increase butane gas efficiency while protecting the thermal power of the gas range outdoors.

One side of the support 30 may be connected to the upper surface 102 and the other side may be connected to the upper portion of the gas range. The support 30 may support the main body 10 at the upper portion of the gas range. The second confirmation hole 303 may be formed in the support part 30. The second confirmation hole 303 may penetrate the side surface of the support part 30.

The support (S) in two pairs, each pair may be symmetrically formed around the flame spray unit (F).

The gas stove thermal protection device 100 may include a main body 10, a seating unit 20, and a support unit 30. The first support groove 108 may be formed in the main body 10. The first support groove 108 may be located on the inclined surface 103. The first support groove 108 may be formed to be inclined along the inclined surface 103. The first support groove 108 may be formed through the inclined surface 103. The first support groove 108 may be two pairs. The first support grooves 108 may be symmetrically formed with respect to the fireball 101 and may be disposed to face each other in pairs.

(P) can be seated.

Conventional fire protectors do not include a structure for stably supporting the lower portion of a large cooking vessel was able to apply only a container equal to or smaller than the diameter of the fire protector. In addition, since the use of a large cooking container fixture has a problem that the fixture cost and inconvenience increases.

In contrast, the gas range thermal protection device 100 uses the seating portion 20 to stably maintain the cooking vessel P even when the lower end diameter of the cooking vessel P is larger than the diameter of the main body portion 10 using the seating portion 20. It may be seated on the upper portion of the body portion (10).

In addition, the discharge space 1071 may discharge combustion gas such as soot or carbon monoxide, which may be generated while the gas in the gas range is burned.

On the other hand, conventionally, when cooking using a large diameter cooking vessel, the lower surface of the cooking vessel and the upper surface of the thermal protector may not have a discharge space. Therefore, in the related art, it is difficult to discharge the combustion gas, so that the risk of the flashback extinguishing phenomenon and overheating may be increased while the flame bursts momentarily.

The air moved into the body portion 10 through the first air inlet holes 105 and the second air inlet holes 107 may increase in temperature by the flame of the gas range. The air whose temperature is raised may rise to the upper portion of the main body to naturally discharge the outside of the main body 10 through the discharge space 1071. That is, the gas stove thermal protection device 100 may improve the butane gas efficiency of the gas range while circulating the air into and out of the body portion 10 through the air convection phenomenon.
