The method is simple and feasible, can actively probe the methane concentration of the environment and actively probe the environment temperature, and controls the rotating speed of the heat dissipation fan according to the current environment to perform active heat dissipation work.

[0042] The control method of the stove in the embodiment specifically includes the following steps:

[0043] In step S101, a plurality of concentration levels are divided according to the methane concentration value of the gas leakage.

[0044] In the embodiment, the first concentration level, the second concentration level and the third concentration level are divided according to the methane concentration value of the gas leakage, and the methane concentration value of the first concentration level is less than the methane concentration value of the second concentration level, the methane concentration value of the second concentration level is less than the methane concentration value of the third concentration level, and the methane concentration value of the third concentration level is less than the concentration threshold value.

[0045] In step S102, the stove is started, and the current methane concentration value in the shell is detected.

[0046] After the stove is started, it is first judged whether the external mains is connected or not. If yes, the charging battery is charged. If no, the charging battery is started to supply power. Then, the current methane concentration value in the shell is detected.

[0047] In step S103, it is judged whether the current methane concentration value is greater than the concentration threshold value. If yes, the work is stopped and an alarm signal is sent. If no, the temperature value in the shell is detected.

[0048] In the embodiment, when the current methane concentration value is greater than the concentration threshold value, the stove is controlled to stop working and send an alarm signal, and at the same time, the mains power supply is turned off, and the charging battery is started to supply power.

[0049] In step S104, the rotating speed of the heat dissipation fan is calculated according to the concentration level of the current methane concentration value and the current temperature value, and the heat dissipation fan rotates at the calculated rotating speed.

[0050] In the embodiment, the rotating speed of the heat dissipation fan is calculated by the following formula: n = (s +

[0051] (T / 25))*a, wherein n is the rotating speed of the heat dissipation fan, s is the concentration level size of the current methane concentration value, T is the current temperature value in the shell, 25 is 25 DEG C, and a is a coefficient.

[0052] More preferably, if the current methane concentration value is in the first concentration level, s is 1, the heat dissipation fan rotates at the calculated rotating speed, and the stove is controlled to ignite;

[0053] If the current methane concentration value is in the second concentration level, s is 2, the heat dissipation fan rotates at the calculated rotating speed, and the range hood is started to exhaust;

[0054] If the current methane concentration value is in the third concentration level, s is 3, the heat dissipation fan rotates at the calculated rotating speed, the range hood is started to exhaust, and the mains power supply is turned off and the charging battery is started to supply power.

[0055] In addition, a is 800 to 1800, and preferably, a is 1050.

[0056] The above only describes some embodiments of the present application. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are all within the protection scope of the present application.
