Fig. 9 is a first flowchart of a temperature control method of a gas stove according to an embodiment of the present invention. Referring to fig. 1 to 9, the temperature control method of the gas range of the present embodiment includes:
s101: a first temperature value of the panel 1 or of the drip tray 3 detected by the temperature sensor 4 at a first moment is acquired.
Specifically, the temperature sensor 4 may detect the temperature of the panel 1 or the drip tray 3 in real time, or the temperature sensor 4 detects the temperature of the panel 1 or the drip tray 3 at preset time intervals. It should be noted that the preset time interval may be set according to actual requirements, for example, the temperature sensor 4 detects every 30S, and then the control board acquires the temperature value detected by the temperature sensor 4. For example, in the present embodiment, the temperature sensor 4 is specifically attached to the inner surface 30 of the liquid containing tray 3, and what the temperature sensor 4 specifically detects is the temperature of the liquid containing tray 3, that is, the temperature collected by the control board is the temperature of the liquid containing tray 3.
S102: whether to close the electromagnetic valve for controlling the intake air is determined according to the first temperature value.
Optionally, the control board collects a first temperature value of the panel 1 or the liquid containing tray 3 detected by the temperature sensor 4 at a first time, and if the first temperature value is greater than or equal to a preset threshold, the control board directly controls the electromagnetic valve to close. If the first temperature value is smaller than the preset threshold value, the temperature sensor 4 continues to detect. It should be noted that the preset threshold may be set according to actual conditions. For example, when the pot on the gas stove is not dried, the temperature of the panel 1 or the liquid containing tray 3 does not exceed 200 ℃, if the temperature value detected by the temperature sensor 4 collected by the control board at the moment exceeds 200 ℃, the fact that the pot on the gas stove is dried is meant, and at the moment, the control board immediately sends an indicating signal to the valve body, so that the valve body closes the electromagnetic valve. The electromagnetic valve is a valve for controlling air intake, and the electromagnetic valve can be specifically arranged in the valve body. It will be understood by those skilled in the art that the solenoid valve will shut off to stop the gas inlet and the gas burner will shut off to stop heating.
Fig. 10 is a second flowchart of a temperature control method of a gas stove according to an embodiment of the present invention. Referring to fig. 10, the present embodiment provides another temperature control method of a gas range, including:
s201: the method comprises the steps of collecting a first temperature value of a panel or a liquid containing disc detected by a temperature sensor at a first moment.
Specifically, this step is the same as step S101 described above, and will not be described in detail here.
Optionally, step S102 includes the following steps:
s202: whether the control board receives the first temperature value.
Specifically, the control board collects a first temperature value detected by the temperature sensor 4, if the control board does not receive the first temperature value, step S203 is executed, and if the control board receives the first temperature value, step S204 is executed.
S203: the buzzer alarms.
Wherein, be provided with bee calling organ in the drain pan 2, bee calling organ is connected with the control panel electricity, if the control panel does not receive temperature data, makes bee calling organ send out the police dispatch newspaper sound to give out the suggestion to the user. The specific location of the buzzer is not limited in the present invention.
It should be noted that, in other implementation manners, the buzzer may be replaced by an indicator light, and when the control board does not receive the temperature data, the indicator light lights up or flashes, and may also perform an alarm function, and it is understood that the indicator light is generally disposed at a place where a user can see. Of course, a buzzer and an indicator lamp can be arranged at the same time, and if the control panel does not receive the temperature data, the buzzer sends out an alarm sound and the indicator lamp lights up or flickers.
S204: and judging whether the first temperature value is greater than a first preset threshold value.
If the control board receives the temperature data sent by the temperature sensor 4, the control board determines whether the received temperature is greater than a first preset threshold, for example, the first preset threshold is 180 ℃. If the temperature is greater than 180 ℃, executing step S205; if the temperature does not reach 180 ℃, the process returns to S201, and the temperature sensor 4 continues to detect the temperature of the panel 1 or the drip tray 3. It should be noted that 180 ℃ is only for convenience of description, and may be set according to actual conditions.
S205: and acquiring a second temperature value detected by the temperature sensor at a second moment, determining the temperature difference between the second temperature value and the first temperature value, and judging whether the temperature difference is greater than a preset temperature difference.
Specifically, if the control board determines that the temperature at the first time reaches a first preset threshold, a second temperature value detected at a second time is obtained, where the second time is any time after the first time. After the second temperature value is obtained, the temperature difference (i.e., temperature rise) between the second temperature value and the first temperature value is determined, and if the temperature difference is greater than the preset temperature difference, step S207 is executed. If the temperature difference is less than or equal to the predetermined temperature difference, step S206 is executed. For example, it is determined whether the temperature of the panel 1 or the liquid containing tray 3 is over 5K within 30S, and if the temperature is not over 5K within 30S, S206 is performed. It should be noted that the preset temperature difference is specifically set according to actual conditions.
And S206, judging whether the temperature value of the temperature sensor at the third moment is greater than a second preset threshold value.
Specifically, when the difference between the temperature detected at the second time and the temperature detected at the first time is less than or equal to the preset temperature difference, it is continuously determined whether the temperature value of the temperature sensor at the third time is greater than a second preset threshold, and it can be understood that the third time is any time after the second time. Because the pan is in the continuous heating, consequently, the second is predetermine the threshold and is greater than first predetermineeing the threshold.
For example, if the temperature of the panel 1 or the liquid containing tray 3 does not exceed 5K within 30S, the control board continues to determine whether the temperature reaches 220 ℃, and if not, the control board returns to S201, and the temperature sensor 4 continues to detect the temperature of the panel 1 or the liquid containing tray 3. If so, S207 is executed. It should be noted that the temperature of 220 ℃ is only for convenience of description, and can be specifically set according to actual conditions.
S207: the electromagnetic valve is controlled to be closed.
Specifically, the control panel sends an indication signal to the valve body, and the indication signal is used for controlling the electromagnetic valve to close. For example, if the temperature of the panel 1 or the liquid containing tray 3 exceeds 5K or reaches 220 ℃ within 30S, which means that the cooker on the gas stove is dry-burned, the control board immediately sends an indication signal to the valve body, so that the valve body closes the electromagnetic valve. The electromagnetic valve is a valve for controlling air intake, and the electromagnetic valve can be specifically arranged in the valve body. It will be understood by those skilled in the art that the solenoid valve will shut off to stop the gas inlet and the gas burner will shut off to stop heating.
Optionally, the temperature control method further includes:
s208, judging whether the electromagnetic valve is closed or not;
s209, alarming by a buzzer;
and S210, stopping detecting the temperature.
Specifically, the control board further determines whether the electromagnetic valve is closed, and if not, S209 is executed to make the buzzer give an alarm to the user to remind the user to close the gas stove. If the solenoid valve is closed, S210 is executed and the temperature sensor 4 stops detecting.
According to the temperature control method of the gas stove, the first temperature value of the panel or the liquid containing disc detected by the temperature sensor at the first moment is collected, and the control panel determines whether to close the electromagnetic valve for controlling air inlet according to the collected temperature value, so that the purpose of dry burning prevention is effectively achieved, and the detection is rapid and convenient; moreover, the temperature sensor is arranged in the space formed by the panel and the bottom shell, so that the temperature sensor is prevented from being influenced by severe environmental factors such as oil stains and the like, and the service life of the temperature sensor is prolonged; in addition, the temperature sensor in the gas stove detects the temperature of the panel or the liquid containing plate, and the temperature sensor does not need to be in direct contact with a cooker, so that a plurality of types of cookers such as pans and the like can be used on the gas stove.
