Abstract
A stove gas burner with a fan comprises a gas burner, an air box, the fan, an air inlet pipe, a nozzle and a gas valve, wherein the gas burner comprises an injection pipe; the gas inlet pipe is connected with the gas inlet pipe through a gas inlet pipe wall, and the gas inlet pipe is communicated with the gas inlet pipe wall through a gas inlet pipe; the temperature change of the thermistor causes voltage change, and the signal of the voltage change is transmitted to the circuit board which controls the rotating speed of the fan. Due to the adoption of the structure, the voltage change signal of the thermistor is transmitted to the circuit board, and then the circuit board controls the rotating speed of the fan; the reasonable matching of fuel gas and air is realized, the combustion is sufficient, and the energy efficiency is improved.
Description
Technical Field
The invention relates to a gas cooker.
Background
At present prior art, a take cooking utensils gas burner of fan, includes drain pan, panel, gas burner, bellows, fan, intake pipe, nozzle and gas valve, and the gas burner is including drawing penetrating the pipe, and bellows are established at the tip of drawing penetrating the pipe, and bellows and drawing penetrate the pipe intercommunication, and the nozzle passes bellows and stretches into to draw penetrating intraductally, and gas valve, intake pipe and nozzle communicate in proper order. There are problems in that: the proportion of fuel gas and air is not matched, the rotating speed of the fan is not matched with the fuel gas flow, the combustion is insufficient, and the energy efficiency is low.
Disclosure of Invention
The purpose of the invention is: the utility model provides a take cooking utensils gas burner of fan, it can be according to the gas flow, the rotational speed of control fan, reaches gas flow and air quantity proportion and suits, and then improves the efficiency.
The invention is realized by the following steps: a stove gas burner with a fan comprises a gas burner, an air box, the fan, an air inlet pipe, a nozzle and a gas valve, wherein the gas burner comprises an injection pipe; it is characterized in that: also comprises a circuit board and a thermistor,
the power supply circuit on the circuit board supplies power to the thermistor, the thermistor is attached to the outer surface of the air inlet pipe, and the fuel gas flowing through the air inlet pipe is subjected to heat exchange with the thermistor through the wall of the air inlet pipe; the temperature change of the thermistor causes voltage change, and the signal of the voltage change is transmitted to the circuit board which controls the rotating speed of the fan.
According to the stove gas burner with the fan, due to the adoption of the structure, a voltage change signal of the thermistor is transmitted to the circuit board, and then the circuit board controls the rotating speed of the fan; the reasonable matching of fuel gas and air is realized, the combustion is sufficient, and the energy efficiency is improved.
Drawings
Fig. 1 is a front view of the present invention.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, a gas burner of a stove with a fan comprises a gas burner 1, a wind box 2, a fan 3, a nozzle 6, an air inlet pipe 4 and a gas valve 5, wherein the gas burner 11 comprises an ejector pipe 11, the wind box 2 is arranged at the end part of the ejector pipe 11, the wind box 2 is communicated with the ejector pipe 11, the nozzle 6 penetrates through the wind box 2 and extends into the ejector pipe 11, and the gas valve 5, the air inlet pipe 4 and the nozzle 6 are communicated;
and further includes a circuit board (not shown in the figure), a thermistor 7,
a power supply circuit on the circuit board supplies power to the thermistor 7, and the thermistor 7 is attached to the outer surface of the air inlet pipe 4; the gas flowing through the gas inlet pipe 4 exchanges heat with the thermistor 7 through the wall of the gas inlet pipe 4; the temperature change of the thermistor 7 causes voltage change, and a signal of the voltage change is transmitted to a circuit board which controls the rotating speed of the fan 3.
When the invention is used, when the gas valve 5 is opened, gas enters the injection pipe 11 through the gas inlet pipe 4 and the nozzle 6. When the gas flows through the gas inlet pipe 4, the heat on the wall of the gas inlet pipe 4 is taken away, so that the temperature of the thermistor 7 attached to the outer surface of the wall of the gas inlet pipe 4 is changed, and the change of the temperature of the thermistor 7 causes the voltage change; that is, the temperature of the thermistor 7 changes due to the change of the gas flow, and the resistance value of the thermistor 7 also changes along with the change of the gas flow, so that the voltage drop across the thermistor 7 is the output signal voltage of the gas flow. The signal of voltage change transmits the circuit board, and the rotational speed of fan 2 is controlled to the circuit board, realizes that air quantity and gas volume match.
What has been described above is merely a preferred embodiment of the present invention. It should be noted that a person skilled in the art could make several modifications and variations without departing from the principle of the present invention, which should also be regarded as the protection scope of the present invention.
