Description

Technical Field

[0001] The invention belongs to the technical field of burners, and in particular relates to an inner rotating fire anti-dry burning burner and a gas cooker using the same. Background Art

[0002] The internal rotating burner can form a flame that rotates inward from the edge of the combustion area during combustion. The rotation process of the gas enhances the disturbance of the airflow, so the gas can be better mixed with the secondary air, making the combustion more thorough and reducing the generation of harmful gases such as carbon oxides. On the other hand, the inward rotating flame can make the flame more concentrated, thereby avoiding the waste of heat energy.

[0003] However, the burner has certain dangers during use. For example, if the water in the pot has dried up during cooking, if the burner continues to burn in this case, it may cause a fire. Therefore, people in this field set a temperature sensor to detect the temperature of the bottom of the pot in real time to prevent dry burning. However, since the flame of the inward-rotating burner gathers inward, it is easy to affect the temperature measurement accuracy of the temperature sensor, and long-term flame radiation can easily make the temperature sensor fail. Summary of the invention

[0004] In order to solve the above problems, the present invention provides an internal rotating fire anti-dry burning burner, which reduces the temperature around the temperature sensor to make the temperature measurement more accurate.

[0005] Another object of the present invention is to provide a gas cooker.

[0008] Preferably, the thermal insulation assembly comprises a thermal insulation sleeve.

[0009] Preferably, a gap is left between the thermal insulation sleeve and the temperature detection assembly, and the gap forms a first cooling channel.

[0014] Preferably, the diameter of the circle where the plurality of second air holes are located is smaller than the diameter of the fire barrier.

[0015] Preferably, the top of the thermal insulation sleeve is a trumpet-shaped expansion structure.

[0029] Example 1

[0030] Embodiment 1 of the present invention provides an internal rotation fire prevention dry burning burner, such as Figure 1 As shown, it includes a burner head 1, an inner fire cover 2, an outer fire cover 3, a temperature detection component 4 and a heat insulation component 5; the inner fire cover 2 and the outer fire cover 3 are both arranged on the burner head 1, the temperature detection component 4 penetrates the burner head 1 and the inner fire cover 2 and is arranged to collect the temperature of the pot on the burner to prevent the burner from burning dry, and the heat insulation component 4 is arranged between the inner fire cover 2 and the temperature detection component 4 to prevent the flame of the burner from affecting the measurement accuracy of the temperature detection component 4;

[0031] Specifically, both the inner fire cover 2 and the outer fire cover 3 are provided with an inner rotating fire hole 21, and the inner rotating fire hole 21 enables the burner to form a flame rotating inward from the edge of the combustion area when burning;

[0032] Thus, by adopting the above structure, during the operation of the burner, the temperature detection component 4 is used to prevent the burner from burning dry, and the detection accuracy of the temperature detection component is ensured by the setting of the heat insulation component 5 to avoid failure due to flame radiation.

[0033] like Figure 2-3 As shown, the thermal insulation assembly 5 includes a thermal insulation sleeve 51;

[0034] Specifically, the heat insulation sleeve 51 is annular and is disposed around the temperature detection assembly 4;

[0035] In order to effectively block the influence of flame on the temperature detection assembly 4 , the top of the heat insulation sleeve 51 is higher than the plane where the inner fire cover 2 and the outer fire cover 3 are located.

[0036] A gap is left between the heat insulation sleeve 51 and the temperature detection assembly 4, and the gap forms a first cooling channel 52;

[0037] In this way, during the combustion process of the burner, air convects through the first cooling channel 52 to achieve cooling of the temperature detection component 4.

[0038] The thermal insulation assembly 5 further includes a positioning member 55, which is located at the bottom of the thermal insulation sleeve 51 and is used to fix the thermal insulation sleeve 51; the positioning member 55 is annular;

[0039] In order to allow sufficient secondary air to be added during the combustion process of the burner, the end surface of the positioning member 55 is provided with a plurality of second air holes 551;

[0040] In order to prevent the second air holes 551 from being blocked by the bottom of the heat insulation sleeve 51 , the diameter of the circle where the second air holes 551 are located is larger than the diameter of the heat insulation sleeve 51 .

[0041] The top of the heat insulation sleeve 51 is a trumpet-shaped expansion structure, which can effectively increase the radiation protection area and reduce the influence of flame radiation on the temperature detection component 4.

[0042] In a specific implementation, the temperature detection component 4 is generally a temperature sensor.

[0043] Working process:

[0044] When the burner 1 is working, the inner rotating fire holes 21 on the inner fire cover 2 and the outer fire cover 3 generate flames, and the flames heat the pots located on the burners;

[0045] During the heating process, the temperature of the pot bottom is collected through the temperature sensor to prevent the burner from burning dry;

[0046] During the operation of the temperature sensor, the annular heat-insulating sleeve 51 fixed on the positioning member 55 isolates the temperature sensor from the surrounding flame, effectively preventing the surrounding flame from affecting the measurement accuracy of the temperature sensor, and the top of the heat-insulating sleeve 51 is a trumpet-shaped expansion structure, which can effectively increase the radiation protection area and reduce the influence of flame radiation on the temperature sensor; and because the top of the heat-insulating sleeve 51 is higher than the plane where the inner fire cover 2 and the outer fire cover 3 are located, specifically, the top of the heat-insulating sleeve 51 is higher than the height of the flame generated by the inner fire cover 2 and the outer fire cover 3, therefore, the flame will not burn the temperature sensor at all;

[0047] Furthermore, during the combustion process of the burner, air convects through the first cooling channel 52, thereby achieving a cooling of the temperature sensor;

[0048] Furthermore, the second air hole 551 provided on the end surface of the positioning member 55 ensures that the secondary air supply is sufficient during the combustion of the burner, thereby making the combustion more complete.

[0049] Example 2

[0050] Embodiment 2 of the present invention provides an internal rotation fire prevention dry burning burner, such as Figure 4-7 As shown, the difference between it and Example 1 is:

[0051] The heat insulation assembly 5 further includes a fire barrier 53, and a gap is left between the fire barrier 53 and the heat insulation sleeve 51, and the gap forms a second cooling channel 54;

[0052] In this way, the temperature around the temperature sensor is reduced through the double protection of the heat insulation sleeve 51 and the fire barrier 53.

[0053] The fire barrier 53 extends out of the inner fire cover 2, and a plurality of first air holes 531 are arranged on the peripheral surface of the extended portion;

[0054] In this way, the first air hole 531 and the second air hole 551 work together to allow sufficient secondary air to be added during the combustion process of the burner, thereby making the combustion more complete.

[0055] In order to prevent the fire barrier 53 from blocking the second air holes 551 , the diameter of the circle where the second air holes 551 are located is smaller than the diameter of the fire barrier 53 .

[0056] This embodiment reduces the temperature around the temperature sensor through double-layer heat insulation and double-layer cooling channels, thereby ensuring the measurement accuracy of the temperature sensor.

[0057] Example 3

[0058] Embodiment 3 of the present invention provides a gas cooker, which includes the internal rotating fire prevention dry burning burner described in Embodiment 1 or Embodiment 2.

[0059] In this embodiment, the burner with the heat insulation component is applied to the gas cooker, so that the operation of the gas cooker is more stable.

[0060] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
