[0078] Figure 3 A flowchart of a method for detecting smoke from a smart kitchen appliance provided in Embodiment 1 of this disclosure is shown below. Figures 1-2 As shown, the smart kitchen appliance includes a thermocouple 1 and distance sensors (e.g., the number of distance sensors is 3, specifically, such as...). Figure 2 As shown, the first distance sensor 2, the second distance sensor 3, and the third distance sensor 4), and the thermocouple are set outside the inner ring flame hole of the smart kitchen appliance. The distance sensors can be set on the horizontal surface of the smart kitchen appliance chassis, or at other horizontal positions within the smart kitchen appliance; for example... Figure 3 As shown, the flue gas detection method includes:

[0079] S1. Obtain the real-time temperature value of the thermocouple in the smart kitchen appliance;

[0080] In this embodiment, the smart kitchen appliance can be a stove, and the temperature is related to the heat output. Generally, the higher the heat output, the higher the temperature.

[0081] S2. In response to a real-time temperature value being greater than or equal to a preset temperature value, obtain the first angle formed between the flame root to the middle of the flame and the horizontal plane of the smart kitchen appliance, and the second angle formed between the middle of the flame and the flame head and the horizontal plane of the smart kitchen appliance.

[0082] In this embodiment, in response to a real-time temperature value being greater than or equal to a preset temperature value, it is determined that the smart kitchen appliance is in a high or medium heat state, and the first angle formed between the flame root to the middle of the flame and the horizontal plane of the smart kitchen appliance, and the second angle formed between the middle of the flame and the flame head and the horizontal plane of the smart kitchen appliance are obtained.

[0083] In this embodiment, the first angle is the angle at which the flame emerges, and the first angle indicates the amount of primary air; the second angle is the angle at which the flame rises to the bottom of the pot, and the second angle indicates the amount of secondary air.

[0084] S3. Compare the first angle with the first preset angle and the second angle with the second preset angle, and detect the flue gas status of the smart kitchen appliance based on the comparison results.

[0085] In this embodiment, high flames result in high smoke levels and high gas pressure, which in turn leads to high thermocouple temperatures. Medium flames with high pressure also result in high thermocouple temperatures. Low flames typically involve inner-ring combustion, where the load is small and the smoke level is low. The smoke level is determined by the flame angle during inner-ring combustion. The flame emerging from the burner hole generally burns outwards first, then upwards. The angle observed during normal smoke level calibration indicates the smoke level. If combustion is complete, the smoke level is low, and the flame angle is large. If combustion is incomplete, indicating insufficient primary / secondary air, the flame at the first angle will lengthen, and the flame at the second angle will lengthen towards the outer ring (as secondary air enters from the outer ring).

[0086] It should be noted that the preset temperature value, the first preset angle, and the second preset angle are all set according to the actual situation, and no specific limitations are made here.

[0090] In this embodiment, a line formed between the first distance value and the second distance value forms a first angle with the horizontal plane of the smart kitchen appliance; a line formed between the second distance value and the third distance value forms a second angle with the horizontal plane of the smart kitchen appliance.

[0091] In an optional embodiment, S3 includes:

[0092] In response to the first angle being less than the first preset angle and the second angle being less than the second preset angle, the smoke state of the smart kitchen appliance is detected as abnormal, and the smoke volume is greater than the first preset smoke volume.

[0093] Wherein, the first preset angle is smaller than the second preset angle;

[0094] Flue gas detection methods also include:

[0095] If the smoke status of the smart kitchen appliance is detected to be abnormal and the smoke volume exceeds the first preset smoke volume, it is determined that the smoke exceeds the standard. The fire power of the smart kitchen appliance is turned off, the range hood is controlled to the maximum fan speed, and an alarm message is output to remind the user to pay attention.

[0096] In an optional embodiment, S3 further includes:

[0097] In response to the first angle being less than the first preset angle and the second angle being greater than or equal to the second preset angle, or the first angle being greater than or equal to the first preset angle and the second angle being less than the second preset angle, the smoke state of the smart kitchen appliance is detected as abnormal, and the smoke volume is greater than the second preset smoke volume and less than the first preset smoke volume.

[0098] Wherein, the first preset angle is smaller than the second preset angle; the first preset flue gas volume is greater than the second preset flue gas volume;

[0099] Flue gas detection methods also include:

[0100] If the smoke status of the smart kitchen appliance is detected to be abnormal, and the smoke volume is greater than the second preset smoke volume but less than the first preset smoke volume, it is determined that the smoke volume is too high. The firepower of the smart kitchen appliance is then adjusted to low, and the range hood is set to medium fan speed.

[0101] In an optional embodiment, S3 further includes:

[0102] In response to the first angle being greater than or equal to the first preset angle and the second angle being greater than or equal to the second preset angle, the smoke state of the smart kitchen appliance is detected as normal.

[0103] Wherein, the first preset angle is smaller than the second preset angle;

[0104] Flue gas detection methods also include:

[0105] If the smoke from the smart kitchen appliance is detected to be normal, the power level of the smart kitchen appliance and the fan speed setting of the range hood will remain unchanged.

[0106] In an optional embodiment, the flue gas detection method further includes:

[0107] If the real-time temperature value is lower than the preset temperature value, the smart kitchen appliance is set to low heat.

[0108] In an optional embodiment, the flue gas detection method further includes:

[0109] Obtain the current value of the thermocouple in the smart kitchen appliance;

[0110] The current value is converted into the real-time temperature value of the thermocouple.

[0111] In this embodiment, when the smart kitchen appliance is detected to be started, the user is reminded to place the pot on the smart kitchen appliance. The heating status of the smart kitchen appliance is determined by reading thermocouple data. Specifically, the current value in the thermocouple of the smart kitchen appliance is detected by the judgment component and communication module of the smart kitchen appliance, and then the current value is converted into the real-time temperature value of the corresponding thermocouple.

[0112] It should be noted that the judgment component is connected to the communication module, which in turn is connected to the control circuit board inside the range hood. The judgment component sends the status signal of whether the smart kitchen appliance is on or off to the control circuit board inside the range hood through the communication module.

[0113] This embodiment detects the real-time temperature value of the thermocouple in the smart kitchen appliance, combines the angle formed by the flame and the horizontal plane of the smart kitchen appliance, and detects the flue gas state of the smart kitchen appliance based on the comparison result of the angle with the preset angle, thereby improving the detection efficiency and accuracy of flue gas.

[0123] In this embodiment, high flames result in high smoke levels and high gas pressure, which in turn leads to high thermocouple temperatures. Medium flames with high pressure also result in high thermocouple temperatures. Low flames typically involve inner-ring combustion, where the load is small and the smoke level is low. The smoke level is determined by the flame angle during inner-ring combustion. The flame emerging from the burner hole generally burns outwards first, then upwards. The angle observed during normal smoke level calibration indicates the smoke level. If combustion is complete, the smoke level is low, and the flame angle is large.
