Referring to fig. 1 to 6 together, a method for controlling a cooking appliance according to an embodiment of the present invention is applied to the cooking appliance 100 according to the embodiment of the present invention. The cooking appliance 100 includes a heating module 10 and a cavity 20. The operation mode of the cooking appliance 100 includes a normal mode and a preheating mode. The first heating power of the heating module 10 in the preheating mode is greater than the second heating power of the heating module 10 in the normal mode

The control method of the cooking appliance comprises the following steps:

step S1: acquiring a preheating mode of the cooking appliance 100;

step S2: controlling the heating module 10 to heat the cavity 20 with a first heating power according to the preheating mode of the cooking appliance 100, and determining whether the temperature of the cavity 20 is greater than or equal to a first preset temperature, if so, entering step S3, otherwise, returning to step S2;

step S3: and sending first prompt information for prompting the completion of preheating.

So, when cooking appliance 100 entered into the preheating mode, steerable heating module 10 heated cavity 20 with great first heating power in order to realize faster temperature rise to after the temperature in cavity 20 reached first preset temperature, can in time send first prompt information in order to indicate the user to put into cooking appliance 100 with the food of treating boiling, can shorten the time of preheating like this, reduce user latency, promoted user experience. In addition, the control method of the cooking appliance can prompt the user in time by sending the first prompt information, so that the intellectualization is improved.

The heating module 10 may be a heat pipe. The first heating power of the heating module 10 may be set to the maximum power of the heat generating tube (the first heating power may be adjusted), so that the rapid temperature rise of the cavity 20 can be achieved. In addition, since the cooking appliance 100 of the present embodiment separately preheats the food to be heated before heating the food, the preheating time can be greatly shortened as compared with the case where the food is directly placed in the cooking appliance 100 and then the preheating and heating are gradually performed. In addition, when the cooking appliance 100 does not enter the preheating mode, the operation mode of the cooking appliance 100 is continuously acquired. In addition, before acquiring the preheating mode of the cooking appliance 100, the control method of the cooking appliance includes the step of powering on the cooking appliance 100.

For example, in the example shown in fig. 5 to 6 (where the x-axis represents the heating time of the heating module and the y-axis represents the heating power of the heating module 10), the first preset temperature is set to 200 degrees celsius, and when the cooking appliance 100 does not adopt the preheating mode of the present embodiment but uses the power of 1000W for heating (as shown by the line m of fig. 5, it can be understood as the heating power used when the cooking appliance 100 normally heats food), it takes 15min to reach 200 degrees celsius, and when the preheating mode of the present embodiment is adopted and the power of the first heating power (3000W) is used for heating (as shown by the line n of fig. 6), it takes only 5min to reach 200 degrees celsius. Therefore, the warm-up time can be shortened by the control method of the present embodiment.

In the present embodiment, the cooking appliance 100 includes a control module 30 and a prompt module 40. The control module 30 is electrically connected to the heating module 10 and the prompt module 40. The control module 30 is configured to obtain a preheating mode of the cooking appliance 100, control the heating module to heat the cavity 20 with a first heating power according to the preheating mode of the cooking appliance 100, determine whether the temperature of the cavity 20 is greater than or equal to a first preset temperature, control the prompting module 40 to send a prompting message prompting completion of preheating when the temperature of the cavity 20 is greater than or equal to the first preset temperature, and continuously determine whether the temperature of the cavity 20 is greater than or equal to the first preset temperature when the temperature of the cavity 20 is less than the first preset temperature. When the temperature of the cavity 20 is less than the first preset temperature, the heating module 10 continues to heat the cavity 20.

Further, the cooking appliance 100 includes a key 50. The key 50 is electrically connected to the control module 30. The control module 30 can acquire the operation mode of the cooking appliance 100 according to the state of the key 50. In the present embodiment, when the user activates the key 50, the cooking appliance 100 enters the preheating mode.

In some embodiments, the cooking appliance 100 includes a discharge motor 60 mounted to the cavity 20. After controlling the heating module 10 to heat the cavity 20 at the first heating power, the step S2 includes: and judging whether the temperature of the cavity 20 is greater than or equal to a second preset temperature, wherein the second preset temperature is less than the first preset temperature, if so, controlling the exhaust motor 60 to work, and if not, controlling the exhaust motor 60 to be closed. In this way, when the temperature in the cavity 20 is greater than the second preset temperature, the exhaust motor 60 operates to send an air flow into the cavity 20 to lower the temperature in the cavity 20, so as to prevent the cooking appliance 100 from overheating. When the temperature in the cavity 20 is not greater than the second preset temperature, the exhaust motor 60 does not operate to reduce heat dissipation, which can further shorten the preheating time.

It should be noted that, when the second preset temperature is set, the second preset temperature in the cavity 20 may correspond to the surface temperature of the cooking appliance 100. For example, when the surface temperature of the cooking appliance 100 is not greater than the preset surface temperature, the cooking appliance 100 is not overheated, and the exhaust motor 60 may not be turned on to cool down. The temperature inside the cavity 20 corresponding to the preset surface temperature of the cooking appliance 100 may be set to a second preset temperature. Thus, when the temperature in the cavity 20 is not greater than the second preset temperature, the surface temperature of the cooking appliance 100 is not greater than the preset surface temperature, i.e., the cooking appliance 100 is not overheated.

In the present embodiment, the exhaust motor 60 is electrically connected to the control module 30. The control module 30 is configured to determine whether the temperature in the cavity 20 is greater than or equal to a second preset temperature after the heating module 10 heats the cavity 20 with the first heating power, control the exhaust motor 60 to operate when the temperature in the cavity 20 is greater than or equal to the second preset temperature, and control the exhaust motor 60 to turn off when the temperature in the cavity 20 is not greater than the second preset temperature. This can shorten the operation time of the exhaust motor 60 to further shorten the warm-up time.

In some embodiments, after the first prompt message indicating that the preheating is completed is issued, the control method of the cooking appliance 100 includes:

step S4: acquiring the normal mode of the cooking appliance 100, and controlling the heating module 10 to heat the cavity 20 at the second heating power according to the normal mode of the cooking appliance 100. In this way, after the cooking appliance 100 is preheated, the heating module 10 enters the normal mode and can heat food with a second heating power lower than the first heating power, so that the food placed in the cavity 20 can be uniformly heated.

It should be noted that one purpose of setting the second heating power to be smaller than the first heating power is to prevent too much heating power from causing too fast heating, which in turn causes the food to be aged or even carbonized, which in turn affects the taste. After the heating of the heating module 10 at the second heating power is completed, the control module 30 may directly control the heating module 10 to stop heating and turn off the cooking appliance 100 to end.

In this embodiment, the control module 30 is configured to obtain a normal mode of the cooking appliance 100 after the prompt module 40 sends a first prompt message indicating that the preheating is completed, and control the heating module 10 to heat the cavity 20 at the second heating power according to the normal mode of the cooking appliance 100.

Note that the prompt module 40 is, for example, an audible alarm. The control module 30 can acquire the operation mode of the cooking appliance 100 according to the state of the key 50. That is, after the prompt module 40 of the cooking appliance 100 sends a prompt message to prompt completion of the preheating, the user may enable the cooking appliance 100 to enter the normal mode by activating the key 50. That is, the preheating mode of the cooking appliance 100 may be superimposed on the normal mode of the cooking appliance 100. Of course, it is understood that other keys may be separately provided for activating the cooking appliance 100 to enter the normal mode.

In some embodiments, after the temperature of the cavity 20 is greater than or equal to the first preset temperature, the step S3 includes: and controlling the heating power of the heating module 10 to be reduced from the first heating power to a third heating power, wherein the third heating power is smaller than the first heating power. In this way, during the preheating process, when the temperature in the cavity 20 is high, the heating power of the heating module 10 can be reduced to prevent temperature runaway.

It should be noted that the third heating power can be set according to specific situations.

In the present embodiment, the control module 30 is configured to control the heating power of the heating module 10 to be decreased from the first heating power to the third heating power when the temperature in the cavity 20 is greater than or equal to the first preset temperature.

In certain embodiments, step S2 includes: and judging whether the temperature of the cavity 20 is greater than or equal to a third preset temperature, wherein the third preset temperature is greater than the first preset temperature, if so, controlling the heating module 10 to be closed, and if not, continuously controlling the heating module 10 to heat the cavity 20 at the first heating power. In this way, when the temperature of the cavity 20 is high (i.e. reaches the third preset temperature), the heating module 10 can be directly turned off to prevent the normal operation of the cooking appliance 100 from being affected by the overhigh temperature in the cavity 20.

In the present embodiment, the control module 30 is configured to determine whether the temperature in the cavity 20 is greater than or equal to a third preset temperature, and is configured to control the heating module 10 to turn off when the temperature in the cavity 20 is greater than or equal to the third preset temperature, and is configured to control the heating module 10 to heat the cavity 20 at the first heating power when the temperature in the cavity 20 is not greater than the second preset temperature.

Referring to fig. 2, in some embodiments, before controlling the heating module 10 to heat the cavity 20 at the first heating power, the step S2 includes: and judging whether food exists in the cavity 20, if so, sending second prompt information for prompting that the food exists, and if not, controlling the heating module 10 to heat the cavity 20 at the first heating power. In this way, when food exists in the cavity 20, the second prompt message is sent to prompt the user, so as to prevent the food from being aged or carbonized due to the heating of the heating module 10 with larger heating power.

It should be noted that the second prompt message may be, for example, a voice prompt message.

In the present embodiment, the cooking appliance 100 includes the detection module 70. The detection module 70 is electrically connected to the control module 30. The detection module 70 is used for detecting whether food exists in the cavity 20. The control module 30 is configured to determine whether food exists in the cavity 20 according to a detection result of the detection module 70 before the heating module 10 is controlled to heat the cavity 20 at the first heating power, control the prompt module 40 to send out a second prompt message when food exists in the cavity 20, and control the heating module 10 to heat the cavity 20 at the first heating power when food does not exist in the cavity 20.

The detection module 70 may be, for example, an infrared detection module, that is, a module for detecting food by infrared.

In addition, it can be understood that after the second prompt message is sent, the cooking appliance 100 may determine whether the operating mode of the cooking appliance 100 is the heating mode by retrieving the operating mode of the cooking appliance 100, and if so, the heating module 10 may be controlled to heat the cavity 20 with the second heating power. After the prompt message is sent, if the user switches the operating mode of the cooking appliance 100 to the heating mode, the food in the cavity 20 can be directly heated without preheating.
