The support of the gas burner (as shown in fig. 2 and 3) is generally composed of a circular ring 204 surrounding the gas disk and four vertical support plates 206, wherein the support plates 206 are distributed around a central equiangular circumferential array of the circular ring 204, and before use, the combustion temperature monitoring device is installed on the gas burner, for example: the first clamping groove 112 is spliced with the top end of one supporting plate 206, the width of the first clamping groove 112 is similar to the thickness of the supporting plate 206, the first clamping bracket 110 can be fixed on the supporting plate 206, then the gasket clamping groove 140 is spliced with the other two supporting plates 206, the width of the gasket clamping groove 140 is similar to the thickness of the supporting plate 206, the clamping gasket 138 can be fixed on the supporting plate 206, then the box 132 is fastened at the bottom of the gas stove shell by using a screw (holes are needed to be drilled at the bottom of the gas stove shell firstly, the box 132 can be stuck at the bottom of the gas stove shell by using glue), then the input interface 116 on the throttle valve 114 is connected with the output port 120 of the gas bottle 118 by screw threads, the structure of the input interface 116 is identical to the structure of the input port 126 of the gas bottle 124, the structure of the output interface 122 is identical to the structure of the output port 120 of the gas bottle 118, then the fixing support 134 is stuck on the upper surface of the gas stove (a position close to a knob on the stove) by using glue, and the reverse disassembly and the disassembly are finished, namely the disassembly and the disassembly are not affected.

When the gas cooker is used, the cooker 208 is placed on the bracket of the gas cooker, the bottom of the cooker 208 is supported by the four supporting plates 206, the first clamping bracket 110 and the two clamping gaskets 138 form a triangular supporting area, the bottom of the cooker 208 is supported jointly, the stability of the cooker 208 is improved, after the gas is ignited by striking the inner side of the circular ring 204, the flame rises to be in contact with the bottom surface of the cooker 208, under the shielding of the bottom of the cooker 208 and the action of the air pressure in the area of the inner side of the circular ring 204, the flame extends in the centrifugal direction, the temperature sensor 108 is arranged to be in contact with the bottom of the cooker 208 or be spaced apart from the bottom of the cooker 208, when the temperature sensor 108 is arranged to be spaced apart from the bottom of the cooker 208, the temperature sensor 108 detects the temperature in the area between the middle part and the tail end of the flame, the area with the highest flame temperature is the area where the flame is in contact with the bottom of the cooker 208, the temperature detected by the temperature sensor 108 approaches to the heated temperature in the area of the bottom of the highest heated area of the cooker 208. Preferably, the temperature sensor 108 is in contact with the bottom surface of the pan 208, and is capable of directly detecting the temperature of the bottom maximum heated area of the pan 208 (note that, the heated temperature of the bottom maximum heated area of the pan 208 is the temperature near the surface of the pan 208, the temperature of the bottom maximum heated area of the pan 208 is the temperature of the pan 208 itself), when no food is present in the pan 208, the bottom center area of the pan 208 and the bottom maximum heated area of the pan 208 are free of heat transfer medium (other mediums than air, such as food, water, etc.), since the heated amount of the bottom center area of the pan 208 is smaller than the bottom maximum heated area of the pan 208, the temperature of the bottom maximum heated area of the pan 208 is higher than the bottom center area of the pan 208, and when the temperature of the bottom maximum heated area of the pan 208 exceeds the preset maximum temperature, the controller 128 controls the throttle valve 114 to reduce the flow rate (reduce the flow cross-sectional area of the internal air flow), and reduce the gas exhausted from the gas pan, thereby reducing the bottom center area, and when the bottom maximum heated area of the pan 208 is not longer than the preset temperature, the bottom maximum heated area of the pan 208 is lower than the bottom maximum heated area of the pan 208, and the throttle valve 114 is continuously closed until the dry throttle is completely closed. When food is present in the pan 208 but the amount of food is relatively small, the food accumulates in the bottom center region of the pan 208 (for round bottom pan 208, non-pan 208), at which time the temperature of the bottom maximum heated region of the pan 208 remains as a condition for evaluating whether there is dry burning, avoiding burning of the food, because the heat of the bottom maximum heated region of the pan 208 gradually conducts to the bottom center region of the pan 208, sufficient heat is conducted to sufficiently heat a small amount of food in the bottom center region of the pan 208, and when the flame is reduced to a point where the heat conducted by the bottom maximum heated region of the pan 208 to the bottom center region of the pan 208 reaches dynamic equilibrium, the throttle valve 114 no longer continues to decrease, allowing continuous heating of the food at a suitable temperature, preferably, adding water in the bottom center region of the pan 208 until the boundary of water is just inside the bottom maximum heated region surrounding region of the pan 208, heating water until boiling after firing, keeping the boiling state for 10 seconds (allowing the heat of the bottom maximum heated area of the pan 208 to be conducted to the bottom center area of the pan 208 and allowing the bottom maximum heated area of the pan 208 to reach dynamic balance with the heat conducted to the bottom of the pan 208), recording the temperature of the bottom maximum heated area of the pan 208 at this time, taking the recorded temperature value as a preset maximum temperature, since the boiling temperature of water is about 100 degrees celsius (under normal pressure), and since the heat conduction has a postponement property, the temperature of the bottom maximum heated area of the pan 208 is always greater than the temperature of the bottom center area of the pan 208, the preset maximum temperature is greater than 100 degrees celsius, but since the boundary of water is located at a position adjacent to the bottom maximum heated area of the pan 208, the preset maximum temperature is therefore typically not more than 105 degrees celsius, so the preset maximum temperature is preferably set to 103 degrees celsius in the present application. When the food covers the bottom center area of the pan 208 and the bottom maximum heated area of the pan 208, once the temperature of the bottom maximum heated area of the pan 208 is greater than the preset maximum temperature, which indicates that there is a scorching condition of the food in the pan 208 at the bottom maximum heated area of the pan 208, the controller 128 will control the throttle valve 114 to gradually decrease the flow until the temperature of the bottom maximum heated area of the pan 208 is stabilized around 100 degrees celsius, thereby avoiding the food from being scorched. In prior art, often can form the one deck diaphragm at the pan 208 surface after food burns, hinder the heat of the biggest heated area in bottom of pan 208 to food conduction, can further lead to the biggest heated area in bottom of pan 208's temperature to go up continuously, thereby aggravate the food burning condition, this application's burning temperature monitoring device can in time monitor whether the biggest heated area in bottom of pan 208 reaches the ground step of dry combustion or burnt, can in time reduce heating amount when the biggest heated area in bottom of pan 208 temperature reaches the ground step of dry combustion or burnt, until the biggest heated area in bottom of pan 208 temperature steadily keeps the temperature range of non-dry combustion and non-burnt condition, compared with the dry combustion prevention function from the area of gas-cooker in prior art is directly closed after judging that there is dry combustion, this application can avoid appearing judging that there is dry combustion or burnt condition after the food can't carry out subsequent heating and lead to the burning temperature too low (follow-up food can not get abundant heating). The current loop of the battery 130 can be controlled to be opened or closed through the switch adjusting button, and the value of the preset maximum temperature can be adjusted, when heated food is relatively dry, the heat conduction efficiency between the bottom maximum heated area of the pan 208, the food and the bottom center area of the pan 208 is relatively low, misjudgment is relatively easy to occur, and the dry frying cooking mode sometimes needs relatively high temperature, so that the current loop of the battery 130 can be closed through the switch adjusting button at this time, the temperature sensor 108, the controller 128 and the throttle valve 114 are all in a power-off state (preferably, the throttle valve 114 adopts a normally open throttle valve 114 and is in a fully opened state after power-off), the temperature is not monitored any more, the flow of the throttle valve 114 is not controlled any more, the function of the gas stove is not changed at this time, a user can dry fry the food by adopting relatively high temperature as usual, and different requirements can be met.
