The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
Example 1
specifically, the inner fire cover 2 and the outer fire cover 3 are both provided with inner fire swirling holes 21, and the inner fire swirling holes 21 enable the burner to form flames which rotate inwards from the edge of a combustion area when the burner burns;
like this, adopt above-mentioned structure, at the in-process of combustor work, prevent that the combustor from burning futilely through temperature detect subassembly 4, guarantee temperature detect subassembly's detection precision through thermal-insulated subassembly 5's setting, avoid it to receive flame radiation and become invalid.
As shown in fig. 2-3, the insulation assembly 5 includes an insulating sleeve 51;
specifically, the heat insulating sleeve 51 is annular, and is disposed around the temperature detection assembly 4;
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 of the inner fire cover 2 and the outer fire cover 3.
A gap is left between the heat insulating sleeve 51 and the temperature detection assembly 4, and the gap forms a first cooling channel 52;
thus, during combustion in the burner, air is convected through the first cooling passage 52, and cooling of the temperature sensing assembly 4 is achieved.
The heat insulation assembly 5 further comprises a positioning member 55, wherein the positioning member 55 is positioned at the bottom of the heat insulation sleeve 51 and used for fixing the heat insulation sleeve 51; the positioning piece 55 is annular;
in order to ensure that enough secondary air is added in the combustion process of the combustor, a plurality of second air holes 551 are formed in the end face of the positioning piece 55;
in order to prevent the second air holes 551 from being blocked by the bottom of the heat insulating sleeve 51, the diameter of a circle in which the second air holes 551 are located is larger than that of the heat insulating sleeve 51.
The top of the heat insulation sleeve 51 is of a horn-shaped flaring structure, the horn-shaped flaring structure can effectively increase the radiation protection area and reduce the influence of flame radiation on the temperature detection assembly 4.
In a specific implementation, the temperature detection component 4 is typically a temperature sensor.
The working process is as follows:
when the burner 1 works, the inner fire holes 21 on the inner fire cover 2 and the outer fire cover 3 generate flame, and the flame heats a cooker on a burner;
in the heating process, the temperature of the pot bottom is collected through a temperature sensor, so that the burner is prevented from being dried;
in the working process of the temperature sensor, the annular heat insulation sleeve 51 fixed on the fixing piece 51 isolates the temperature sensor from surrounding flames, the measuring accuracy of the temperature sensor is effectively prevented from being influenced by the surrounding flames, the top of the heat insulation sleeve 51 is of a horn-shaped flaring structure, the radiation-proof area can be effectively increased by the horn-shaped flaring structure, and the influence of flame radiation on the temperature sensor is reduced; and because the top of the heat insulating sleeve 51 is higher than the plane of the inner fire cover 2 and the outer fire cover 3, in particular, the top of the heat insulating sleeve 51 is higher than the height of flame generated by the inner fire cover 2 and the outer fire cover 3, the flame can not burn to the temperature sensor at all;
in addition, in the combustion process of the combustor, air is convected through the first cooling channel 52, so that the temperature of the temperature sensor is reduced;
in addition, the second air holes 551 provided in the end surface of the retainer 55 ensure sufficient supply of secondary air during combustion of the burner, thereby making the combustion more sufficient.
Example 2
the insulation assembly 5 further comprises a fire barrier wall 53, a gap is left between the fire barrier wall 53 and the insulation sleeve 51, and the gap forms a second cooling channel 54;
in this way, the temperature around the temperature sensor is reduced by the double protection of the insulating sleeve 51 and the firestop wall 53.
The fire retardant wall 53 extends out of the inner fire cover 2, and the peripheral surface of the extending part is provided with a plurality of first air holes 531;
thus, the first air holes 531 and the second air holes 551 work together, so that sufficient secondary air is added during combustion of the burner, and the combustion is more complete.
In order to avoid the fire retardant wall 53 from blocking the second air holes 551, a number of said second air holes 551 are located on a circle having a diameter smaller than the diameter of the fire retardant wall 53.
The temperature around the temperature sensor is reduced through the double-layer heat insulation and the double-layer cooling channel, and the measurement accuracy of the temperature sensor is guaranteed.
Example 3
An embodiment 3 of the present invention provides a gas cooker including the internal-fire dry-burning prevention burner described in embodiment 1 or embodiment 2.
The embodiment applies the combustor with the heat insulation assembly to the gas cooker, so that the gas cooker can work more stably.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
