The terms "first" and "second" used herein do not denote any particular order or quantity, but rather are used to distinguish one element from another.
The anti-overflow method of the cooking appliance can be applied to the cooking appliance shown in fig. 1. The cooking appliance comprises a cooking pot 100, a temperature detection element, a heater, a timer, an air supply part 200, an overflow detection part 300 and a controller, wherein the temperature detection element, the heater, the timer, the air supply part 200 and the overflow detection part 300 are all electrically connected with the controller. Alternatively, the cooking appliance may be an electric rice cooker.
The temperature detecting element is a thermistor, which is placed at the bottom of the cooking pot 100, and is used for detecting the bottom temperature of the cooking pot 100, so that the temperature of the substance in the cooking pot 100 can be known when cooking is performed; of course, the temperature detecting element may be other temperature sensors, and the setting position thereof may also be changed according to the actual situation, as long as the current temperature of the cooking pan 100 can be detected. The heater is a heating plate or other heating element, and is disposed below the cooking pan 100 and used for heating the cooking pan 100, so as to heat food in the cooking pan 100. The air supply member 200 may be an air pump or a fan, etc., and is provided on the top cover 400 of the cooking appliance for blowing air into the inside of the cooking pot 100 to blow bubbles formed in the pot open, thereby preventing overflowing. The overflow detecting member 300 may be a metal rod, which is disposed on the top cover 400 of the cooking utensil and extends into the cooking pan 100, and when the bubble touches the metal rod, the capacitance between the metal rod and the ground may be changed drastically, so that it may be determined that the substance in the cooking pan 100 is about to overflow or has overflowed.
As shown in fig. 1-2, a control method of a cooking appliance according to an embodiment includes:
s100, acquiring an initial temperature of the cooking pan 100 when cooking is started.
Specifically, the temperature detection element can detect the current temperature of the cooking pot 100, and when cooking starts, the temperature detection element detects that the temperature of the cooking pot 100 is the initial temperature of the cooking pot 100, so that the controller can obtain the initial temperature of the cooking pot 100 when cooking starts according to the temperature detection element.
S200, when the initial temperature is lower than the first preset temperature, controlling the heater to heat the cooking pan 100 with the first power, so that the temperature of the cooking pan 100 reaches a second preset temperature, wherein the second preset temperature is higher than the first preset temperature.
Specifically, when the initial temperature of the cooking pan 100 is less than the first preset temperature, the controller controls the heater to heat the cooking pan 100 at the first power so that the temperature of the cooking pan 100 reaches the second preset temperature. Wherein, the first preset temperature can be any value between 40 ℃ and 45 ℃, and the second preset temperature can be any value between 48 ℃ and 55 ℃. Specifically, in the present embodiment, the first preset temperature is 42 ℃ and the second preset temperature is 50 ℃. It should be noted that the first preset temperature and the second preset temperature can be adjusted according to the difference of different cooking appliances, and are not limited to the values listed above.
S300, acquiring a time t for the temperature of the cooking pan 100 to reach a second preset temperature from the initial temperature.
Specifically, the controller may obtain the time t at which the temperature of the cooking pan 100 reaches the second preset temperature from the initial temperature according to the time t at which the temperature of the cooking pan 100 reaches the second preset temperature from the initial temperature recorded by the timer. Since the specific heat capacity of water is much greater than rice, if the amount of water is more, the heating time of the cooking pan 100 is slower, and thus, the amount of water in the cooking pan 100 can be determined according to the time t when the temperature of the cooking pan 100 reaches the second preset temperature from the initial temperature.
And S400, starting the air sending piece 200 to enable the air sending piece 200 to send air to the interior of the cooking pot 100, wherein the air flow quantity of the air sent to the interior of the cooking pot 100 by the air sending piece 200 is in positive correlation with the time duration of the time t.
Specifically, after the temperature of the cooking pan 100 reaches the second preset temperature, the controller turns on the air-sending piece 200 to make the air-sending piece 200 send air to the inside of the cooking pan 100, thereby blowing bubbles in the pan to prevent overflow.
More specifically, the amount of water in the cooking pot 100 may be determined according to the time t, and the longer the time t is, the more the amount of water in the cooking pot 100 is, the more the amount of water is, the more the overflow phenomenon is likely to occur. By making the air flow quantity of the gas delivered to the inside of the cooking pot 100 by the air delivery member 200 be in positive correlation with the time length of the time t, the greater the water quantity of the water in the cooking pot 100, the greater the air flow quantity of the gas delivered to the inside of the cooking pot 100 by the air delivery member 200, and the material in the cooking pot 100 is ensured not to overflow. Therefore, when the air supplier 200 supplies air to the inside of the cooking pan 100, the power of the heater may be increased, so that the cooking appliance may shorten the cooking time on the premise of ensuring that the substance in the cooking pan 100 does not overflow.
In one embodiment, the step of controlling the heater to heat the cooking pan 100 at the first power when the initial temperature is less than the first preset temperature so that the temperature of the cooking pan 100 reaches the second preset temperature includes:
as shown in fig. 1 and 3, when the initial temperature is less than the first preset temperature, the heater is controlled to heat the cooking pot 100 at the first power until the temperature of the cooking pot 100 reaches the second preset temperature S210.
Specifically, when the initial temperature of the cooking pan 100 is less than a first preset temperature, the controller controls the heater to heat the cooking pan 100 at a first power until the temperature of the cooking pan 100 reaches a second preset temperature.
Further, after the step of controlling the heater to heat the cooking pan 100 with the first power when the initial temperature is less than the first preset temperature until the temperature of the cooking pan 100 reaches the second preset temperature, the method further includes:
s500, controlling the heater to heat the cooking pan 100 with a second power, wherein the second power is greater than the first power.
Specifically, after the temperature of the cooking pan 100 reaches a second preset temperature, the controller controls the heater to heat the cooking pan 100 at a second power to increase the cooking speed; meanwhile, the controller turns on the air-sending member 200 to make the air-sending member 200 send air to the inside of the cooking pot 100, thereby blowing bubbles in the pot to prevent overflowing.
More specifically, the first power is 40% -60% of the maximum power of the heater. By setting the first power to 40% -60% of the maximum power, it can be avoided that the water temperature rises too fast, and the measurement of water-proof quantity is not accurate, and in addition, because the first power is 40% -60% of the maximum power, the rice is soaked in the environment of 42 ℃ -50 ℃ for a relatively long time, the taste of the rice can be improved, and specifically in the embodiment, the first power is 50% of the maximum power of the heater. The second power is the maximum power of the heater, so that under the action of the air-sending piece 200, the cooking appliance can maximally shorten the cooking time on the premise of ensuring that the substance in the cooking pan 100 does not overflow.
In one embodiment, the air supplying member 200 is an air pump, the air pump is driven by PWM (Pulse width modulation), and the air flow rate of the air supplied to the inside of the cooking pan 100 by the air pump is in positive correlation with the PWM duty ratio. The larger the PWM duty is, the larger the air flow amount of the air supplied from the air pump to the inside of the cooking pot 100 is, and when the PWM duty is 100%, the air flow amount is the maximum.
Further, the duty cycle of the PWM is proportional to the duration of time t.
Specifically, the duty ratio of the PWM is increased by 5% every time the duration of time t is increased by 30s, and when the time t is 10min, the duty ratio of the PWM is 100%.
In one embodiment, when the time t is less than the preset time, the air flow rate of the air delivered to the inside of the cooking pan 100 by the air delivery member 200 is positively correlated with the duration of the time t, and when the time t is greater than or equal to the preset time, the air delivery member 200 is controlled to deliver the air with the maximum air flow rate capable of being delivered by the air delivery member 200 to the inside of the cooking pan 100. Specifically, in this embodiment, the preset time is 10min, and when the time t is less than 10min, the duty ratio of the PWM is in direct proportion to the duration of the time t, so that the airflow quantity of the gas delivered by the gas delivering member 200 to the inside of the cooking pan 100 is positively correlated to the duration of the time t; when the duration of the time t is greater than 10min, the controller controls the air feeder 200 to feed the gas with the maximum amount of gas that the air feeder 200 can feed into the cooking pan 100, that is, the duty ratio of the PWM is 100%.
As shown in fig. 1 and 4, in one embodiment, S600, when the initial temperature is higher than the first preset temperature, the heater is controlled to heat the cooking pot 100 at the maximum power, and the air feeder 200 is controlled to feed air into the cooking pot 100 at the maximum air flow rate that the air feeder 200 can feed.
Specifically, when cooking is started, the temperature detection element detects that the initial temperature of the cooking pan 100 is greater than the first preset temperature, which means that in the initial stage, water with a temperature greater than the first preset temperature is used for cooking, and at this time, the controller directly controls the heater to heat the cooking pan 100 at the maximum power, and controls the air supply member 200 to supply air with the maximum air flow amount capable of being supplied by the air supply member 200 to the inside of the cooking pan 100, so that the cooking speed can be maximally increased under the condition that it is ensured that the substance does not overflow.
More specifically, the first preset temperature is 42 ℃, and when the temperature detecting element detects that the initial temperature of the cooking pan 100 is higher than 42 ℃ when cooking is started, it can be stated that in the initial stage, rice is cooked with water at a temperature higher than 42 ℃, and the rice begins to gelatinize in an environment of 42 ℃, so that the taste can be ensured.
As shown in fig. 1, 5 and 7, in one embodiment, the method for controlling a cooking appliance further includes:
s700, information on whether the substance is about to overflow from the cooking pot 100 is acquired according to the detection result of the overflow detecting member 300.
Specifically, the overflow detecting member 300 may detect whether the substance is about to overflow from the cooking pot 100, and when the overflow detecting member 300 detects that the substance is about to overflow from the cooking pot 100, the information is transmitted to the controller.
Illustratively, the overflow detector 300 is mounted on top of the cooking pot 100 as an exposed metal rod. If the bubble touches the metal rod, the capacitance between the metal rod and ground changes dramatically. Therefore, the overflow detecting member 300 can detect not only whether the substance is about to overflow from the cooking pot 100, but also when the substance has overflowed, the overflow detecting member 300 can detect.
And S800, controlling the air flow of the air delivered to the cooking pot 100 by the air delivery piece 200 according to the anti-overflow information.
As shown in fig. 1, 6 and 8, specifically, in S810, if the overflow detecting member 300 detects that the substance is about to overflow, the controller increases the air flow of the air delivered from the air delivering member 200 to the cooking pan 100; if the overflow detector 300 detects that the substance is about to overflow and the gas flow rate of the gas delivered to the cooking pot 100 by the gas delivering part 200 is the maximum value that the gas delivering part 200 can deliver, the controller reduces the heating power of the heater to prevent the substance from overflowing.
In one embodiment, the information on whether the substance is about to overflow from the cooking pot 100 according to the detection result of the overflow detecting member 300 includes:
information on whether the substance is about to overflow from the cooking pot 100 is obtained according to the detection result of the overflow detecting member 300 every preset time period.
Specifically, the overflow detecting member 300 detects whether the substance may overflow from the cooking pot 100 once every preset time period, and if so, increases the gas flow rate of the gas delivered to the cooking pot 100 by the gas delivering member 200, and if the gas flow rate of the gas delivered to the cooking pot 100 by the gas delivering member 200 has been the maximum value, decreases the heating power of the heater to prevent the substance from overflowing.
More specifically, the preset time period is 500ms, the overflow detecting member 300 detects whether there is a substance in the pan to overflow every 500ms, the controller increases the duty ratio of the PWM by 5% if it detects that there is a substance to overflow, and decreases the power of the heater by 10% if the duty ratio of the PWM has reached 100%.
It should be understood that although the various steps in the flow charts of fig. 2-8 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise.
