step 702, detecting a door closing signal;

step 704, starting timing, and controlling the fan to be started under the condition that the timing duration reaches the duration threshold value, so that the exhaust valve can be opened under the pressure action in the cavity during the timing duration.

In this embodiment, when a user opens the door of the cooking appliance, cold air outside the shell assembly 100 enters the cavity 102, when the user closes the door again, the cold air entering the cavity 102 expands with the increase of temperature, when the door is opened, the fan 400 is controlled to stop rotating, and after the door is closed, the fan 400 is opened again after a period of time delay, so that the expanded air can be discharged from the cavity 102 through the discharge port within the period of time delay, and further, while ensuring smooth exhaust, waste of heat in the cavity 102 of the cooking appliance can be reduced, and further, while improving the working efficiency of the cooking appliance, the exhaust of the cavity 102 is realized, and the pressure balance inside and outside the cavity 102 is ensured.

The control method of the cooking appliance can be used for the cooking appliance of any embodiment.

Specifically, the cooking appliance includes a housing assembly 100, a cavity 102 is provided in the housing assembly 100, and food materials can be placed in the cavity 102 for cooking. An exhaust port 104 is provided on the housing assembly 100, the exhaust port 104 is in communication with the cavity 102, and a baffle 202 is provided at the exhaust port 104, the baffle 202 is tightly covered on the exhaust port 104 under the action of an elastic member 204, so as to realize the sealing of the exhaust port 104. During cooking of the food material, the gas in the cavity 102 expands due to the increase in temperature in the cavity 102, thereby increasing the pressure in the cavity 102. After the pressure in the cavity 102 rises, a pressure difference is generated at two sides of the baffle 202, and the baffle 202 is jacked up under the action of high-pressure gas in the cavity 102, so that the gas in the cavity 102 is discharged out of the cavity 102 through the exhaust port 104, and the high-pressure cavity 102 is exhausted.

The cooking utensil further comprises a fan 400, wherein the fan 400 is arranged on the partition 108, and an air outlet of the fan 400 faces the baffle 202. The fan 400 can blow air towards the baffle 202, when food is cooked and no exhaust is needed, the fan 400 is started, and the air blown by the fan 400 can generate pressure on the baffle 202, so that the baffle 202 is tightly covered at the exhaust port 104, and heat in the cavity 102 is prevented from being lost at the exhaust port 104. When the food is cooked and the air is exhausted, the fan 400 stops rotating, and the baffle 202 can open the exhaust port 104 under the action of high-pressure air in the cavity 102, so that the air is exhausted.

The cooking appliance is a steam oven.

Example eleven:

as shown in fig. 8, the control method of the cooking appliance includes:

step 802, controlling the cooking appliance to work;

step 804, detecting an opening signal of the door body;

Step 806, controlling the fan to stop working;

step 808, detecting a door closing signal;

and step 810, starting timing, and controlling the fan to be started under the condition that the timing duration reaches the duration threshold value, so that the exhaust valve can be opened under the pressure action in the cavity during the timing duration.

In this embodiment, before the door closing signal is detected and the blower 400 is controlled to start in a delayed manner, the cooking appliance is ensured to be in a cooking state, the blower 400 is prevented from being turned on when the cooking appliance is not in a cooking state, and accuracy of control of the blower 400 is further improved.

Embodiment twelve:

as shown in fig. 9, the control method of the cooking appliance includes:

step 902, detecting a door closing signal;

step 904, detecting the temperature in the cooking utensil;

step 906, starting timing when the temperature is greater than or equal to the temperature threshold, and controlling the fan to be started when the timing time length reaches the time length threshold so that the exhaust valve can be opened under the pressure action in the cavity within the timing time length.

In this embodiment, after the temperature in the chamber 102 reaches the threshold value, the pressure in the chamber 102 will rise after opening the door again, and if the temperature in the chamber 102 does not reach the threshold value, the pressure in the chamber 102 will not rise in a short time even after opening the door. And then, when the temperature is greater than or equal to the temperature threshold value, the timing is started, so that the fan 400 is started in a delayed manner after the door body is closed for a period of time, and the accuracy of controlling the fan 400 is further improved.
