when the cavity temperature of the cooking appliance 100 is not greater than the preset temperature, the process proceeds to step S30.
The control method of the present embodiment may be implemented by the cooking appliance 100 of the present embodiment, wherein steps S60 and S62 of the control method of the cooking appliance 100 of the present embodiment may be implemented by the control device 30. That is, the control device 30 is configured to determine whether the cavity temperature of the cooking appliance 100 is greater than a preset temperature in a first operating period, and control the first heating element 10 and the second heating element 20 to stop heating when the cavity temperature of the cooking appliance 100 is greater than the preset temperature; when the temperature of the cavity of the cooking appliance 100 is not more than the preset temperature, the first heating member 10 and the second heating member 20 are controlled to be heated according to a first preset heating period.
In this way, by controlling the operating states of the first heating element 10 and the second heating element 20 according to the cavity temperature of the cooking appliance 100 in the third operating period, the effect of saving electric energy can be achieved, and the cooking performance of the electric oven is good.
It should be noted that, in one embodiment, the first preset heating period and the second preset heating period may be the same heating manner.
Specifically, when the cooking appliance is heated in the first working period in the first preset heating period and the third working period in the second preset heating period, in order to avoid the bad taste of the food caused by the overhigh temperature of the cooking cavity 80, in this embodiment, a temperature control mode in an energy saving mode is introduced, that is, if the cavity temperature of the cooking appliance 100 is higher than the preset temperature, the first heating element 10 and the second heating element 20 are controlled to stop heating in this embodiment, so that the temperature of the cooking cavity 80 can be reduced. Meanwhile, as the cavity temperature of the cooking appliance 100 is gradually reduced after the first heating element 10 and the second heating element 20 stop heating, when the cavity temperature of the cooking appliance 100 is again lower than the preset temperature, the heating is continued in the first preset heating period or the second preset heating period.
