The steam for steaming the food is generated by heating water, the first pumping power determines the water flow entering the heating device 4, the first heating power determines the speed of the water converted into the steam, the hot air for baking the food is generated by heating the air, the second pumping power determines the air flow entering the heating device 4, the second heating power determines the air heating speed, the water entering the heating device 4 is fully converted into the steam during steaming, the first pumping power is relatively small, the first heating power is relatively large, the heat of the heating device 4 is timely conducted to the food for baking during baking, the amount of the hot air entering the cooking space 131 is sufficient, the second pumping power is relatively large, and the second heating power is relatively small.

Thus, in some embodiments, the first pumping power is equal to or less than the second pumping power and the first heating power is equal to or greater than the second heating power.

As shown in fig. 1, according to an embodiment of the present invention, when the control device 10 controls the cooking appliance to perform first-baking and then steaming, the second valve port 312 of the three-way valve 31 is communicated with the third valve port 313 to communicate the external atmosphere with the pumping assembly 32, and the pumping assembly 32 is controlled to operate at the third pumping power to control the air flow entering the heating device 4, and the heating device 4 is controlled to operate at the third heating power to ensure that the air entering the heating device 4 is heated to the hot air suitable for baking the food in time, when the baking time reaches the third preset time, the food is baked with enough flavor, the control device 10 then controls the first valve port 311 of the three-way valve 31 to communicate with the third valve port 313 to communicate the water tank 2 with the pumping assembly 32, and the pumping assembly 32 is controlled to operate at the fourth pumping power to control the water flow entering the heating device 4, and the control device controls the heating device 4 to work at a fourth heating power so as to ensure that water entering the heating device 4 is heated and gasified into steam in time until the steaming time reaches a fourth preset time, so that the cooked food has both fragrance and soft and glutinous taste, and the cooking effect is improved.

The steam for steaming the food is generated by heating water, the fourth pumping power determines the water flow entering the heating device 4, the fourth heating power determines the speed of the water converted into the steam, the hot air for baking the food is generated by heating the air, the third pumping power determines the air flow entering the heating device 4, the third heating power determines the air heating speed, the water entering the heating device 4 is fully converted into the steam during steaming, the fourth pumping power is relatively small, the fourth heating power is relatively large, the heat of the heating device 4 is timely conducted to the food for baking during baking, the amount of the hot air entering the cooking space 131 is sufficient, the third pumping power is relatively large, and the third heating power is relatively small.

Therefore, in some specific embodiments, the third pumping power is equal to or greater than the fourth pumping power, and the third heating power is equal to or less than the fourth heating power.

It should be noted that the first preset time, the second preset time, the third preset time and the fourth preset time may be calibrated according to actual conditions, and may be adjusted within an interval of 5 minutes to 180 minutes, for example, to adapt to cooking of different foods.

According to an embodiment of the present invention, during the toasting phase, the pumping power of the pumping assembly 32 is directly correlated with the heating power of the heating device 4, i.e. the greater the pumping power of the pumping assembly 32, the more air is pumped and the greater the heating power of the heating device. During baking, the pumping power of the pumping assembly is large to provide the cooking space 131 with a sufficient amount of air, and the heating device 4 also needs a large heating power to heat the air to a sufficient temperature to ensure that the hot air can bake the food.

As shown in fig. 1, according to an embodiment of the present invention, the cooking appliance further includes a water level detection device 21, the water level detection device 21 is disposed corresponding to the water tank 2 to detect water level information in the water tank 2 and send the water level information in the water tank 2 to the control device 10, the control device 10 controls the cooking appliance to send an alarm message when determining that the water level in the water tank 2 is lower than a preset water level according to the water level information in the water tank 2, and prohibits the cooking appliance from performing first steaming and then baking or first baking and then steaming, and at this time, water is added to the water tank 2 to be higher than the preset water level, so that the cooking appliance can be released from a cooking prohibition state.

Specifically, water level detection device 21 may be a water level sensor, and may be disposed at a lower side of water tank 2 near the bottom, and when the water level in water tank 2 is lower than a preset water level, the water amount in water tank 2 is not satisfied with the water amount required for steaming food, and control device 10 prohibits cooking utensil to steam first and then bake or to bake first and then steam, so as to prevent from steaming food, because the water amount is insufficient, heating device 4 is dried and burned, thereby avoiding potential safety hazards.
