Problems solved by technology

However, the existing anti-boil-dry control methods uniformly use the same anti-boil-dry temperature threshold, and when the temperature of the pot is higher than the anti-boil-dry temperature threshold, it is judged that dry-boiled occurs, which is prone to misjudgment of dry-boiled prevention
At the same time, the user cannot be notified in time to turn off the cooker before the cooker dry-burns or when it starts dry-burning. When the temperature of the cooker reaches the anti-dry-burning temperature threshold, dry-burning has already occurred in the pot and lasted for a certain period of time, which may cause the food in the pot to burn. Carbonization, difficult to clean pots, etc., poor user experience

Embodiment 1

[0201] Embodiment one (see Figure 13 )

[0202] A1, the cooker 20 is turned on.

[0203] A2, the temperature sensor 40 collects the temperature T of the pot 30 k .

[0204] A3. The control device 50 determines the cooking state of the pot 30 . If the pot 30 is in the state of cooking with water, go to step A4; if the pot 30 is in the state of cooking without water, go to step A8.

[0205] A4, the control device 50 according to the boiling temperature T of the pot 30 b The thermal conductivity of the pan 30 is determined.

[0206] A5. The control device 50 determines whether the currently detected temperature of the pot 30 exceeds the alarm temperature threshold corresponding to the thermal conductivity of the pot 30 and the alarm information when cooking with water. If it exceeds, go to step A6; if not, go to step A2.

[0207] A6. The control device 50 controls the buzzer to send an alarm message corresponding to the alarm temperature threshold, and starts timing when ...

Embodiment 2

[0213] Embodiment two (referring to Figure 14 )

[0214] A1, the cooker 20 is turned on.

[0215] A2, temperature sensor 40 collects temperature T k .

[0216] A3. The control device 50 determines the cooking state of the pot 30 . If the pot 30 is in the state of cooking with water, go to step A4; if the pot 30 is in the state of cooking without water, go to step A7.

[0217] A4. The control device 50 determines whether the currently detected temperature of the pot 30 exceeds the alarm temperature threshold corresponding to the alarm information when cooking with water. If it exceeds, go to step A5; if not, go to step A2.

[0218] A5. The control device 50 controls the buzzer to send an alarm message corresponding to the alarm temperature threshold, and starts timing when the cooker 20 sends out the alarm message for the first time.

[0219] A6. The control device 50 judges whether the current accumulative duration exceeds the first preset duration corresponding to the ...

Abstract

The invention discloses an anti-dry-burning control method and an anti-dry-burning system. The anti-dry-burning control method comprises the following steps: collecting temperature of cookware; determining a cooking state of a stove according to the temperature of the cookware; obtaining a corresponding alarm temperature threshold value according to the cooking state of the stove; if the temperature of the cookware is greater than the alarm temperature threshold value, controlling the stove to send out alarm information corresponding to the alarm temperature threshold value, and starting timing when the stove sends out the alarm information for the first time; and when the timing duration is longer than a first preset duration, controlling the stove to close. In the anti-dry-burning control method, the corresponding alarm temperature threshold value is obtained according to the cooking state of the stove, and the stove is controlled to send out the alarm information when the temperature of the cookware is greater than the alarm temperature threshold value; therefore, a user is informed in time before dry burning of the stove or at the beginning of dry burning of the stove. By controlling the stove to close by way of timing, the anti-dry-burning control precision can be improved and the erroneous anti-dry-burning determination is prevented.

Description

technical field [0001] The invention relates to the technical field of cooking utensils, and more specifically, to a control method for preventing dry burning and a system for preventing dry burning. Background technique [0002] In the related art, the anti-boil-dry function set in the household cooker can automatically turn off the cooker when the temperature of the pot reaches the anti-boil-dry temperature threshold. However, the existing anti-boil-dry control method uniformly uses the same anti-boil-dry temperature threshold value, and when the temperature of the pot is higher than the anti-boil-dry temperature threshold value, it is judged that dry-boiled occurs, which is prone to misjudgment of dry-boiled prevention. At the same time, the user cannot be notified in time to turn off the cooker before the cooker dry-burns or when it starts dry-burning. When the temperature of the cooker reaches the anti-dry-burning temperature threshold, dry-burning has already occurred ...
