Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a first embodiment of a control method of a cooking appliance according to the present invention.
In this embodiment, the control method of the cooking appliance includes the steps of:
s10: controlling the water pump to pump water to the steam generator according to the obtained cooking request so as to enable the steam generator to generate steam;
in this embodiment, the cooking appliance mainly converts water pumped from the water tank into high-temperature steam through the steam generator, and conveys the high-temperature steam to the steaming device to heat an object to be cooked placed in the steaming device, and the steam is not required to be generated by heating the cold water to boiling, so that the surface collapse of the flour of the object to be cooked caused by the generation of water vapor with the temperature lower than a target temperature in the process of heating the cold water to boiling is avoided, and the cooking effect of the cooking appliance is improved. Since one of the improvement points of the present invention is to heat the object to be cooked directly using the steam of the target temperature, after receiving the cooking request of the user, the water pump may be controlled to pump water to the steam generator directly according to the cooking request to generate the steam according to the cooking request. The cooking request may be generated in response to the detected user action, or may be generated directly in response to the received user setting information. The cooking request comprises cooking parameters, such as heating time length, heating temperature and the like, which are automatically generated for different food materials cooked by a user. After the cooking request is received, the cooking appliance controls the steam generator to be heated to a first preset temperature according to preset operation logic, and then controls the water pump to pump water in the water tank into the steam generator to be heated so as to generate high-temperature steam which can be directly used for heating an object to be cooked in the steaming device.
S20: monitoring a temperature value of a steam outlet of the steam generator, and adjusting the flow rate of the water pump and/or the power adjusting ratio of the steam generator according to the temperature value;
because the object to be cooked can ensure a good cooking effect only under the action of the steam at the target temperature, the temperature value of the steam outlet of the steam generator needs to be monitored in real time in the process of controlling the steam generator and the water pump to output the steam at the target temperature, so that the water pumping flow of the water pump can be adjusted in real time according to the temperature value and/or the power regulation ratio of the steam generator can be adjusted in real time. The specific operation is as follows: and arranging a temperature sensor or a temperature sensing bulb at the position of a steam outlet of the steam generator, and adjusting the flow of the water pump according to the temperature data fed back by the temperature sensor or the temperature sensing bulb in real time and the target temperature in the cooking request or adjusting the power regulation ratio of the steam generator after the flow limit value of the water pump is adjusted. Because the adjusting commands acting on the water pump and the steam generator are PWM (pulse width modulation) signals, the duty ratio of the water pump can be preferentially adjusted to be small when the temperature difference between the temperature value and the target temperature is large, the flow rate of the water pump is reduced, and the power adjusting ratio of the steam generator is adjusted to be large when the flow rate of the water pump is adjusted to the minimum limit value; similarly, when the temperature difference between the temperature value and the target temperature is small, the duty ratio of the water pump is preferentially adjusted to increase the flow rate of the water pump, and when the flow rate of the water pump is adjusted to be larger than the maximum limit value, the power adjustment ratio of the steam generator is adjusted to be smaller so as to enable the temperature value of the steam outlet to be close to the target temperature.

The set time period has different choices according to different cooking objects, for example, in the embodiment, when the user selects steamed stuffed bun steaming, the set time period is generally 9min to 11min, and preferably 10 min. Because after the water pump stops pumping water, still remain some water in steam generator's the pipeline, for avoiding breeding the bacterium, influence the culinary art effect, need control steam generator continues to heat and stops after first preset duration again to steam generator supplies power, with will remain steam generator's water is all evaporated and is discharged for steam. The first preset time period is 8 seconds to 12 seconds, and preferably 10 seconds.

s40: the method comprises the steps of obtaining a cooking request of a user, controlling a water pump to pump a preset amount of water into a steam generator according to the cooking request, and controlling the steam generator to be heated to a first preset temperature.
In this embodiment, in order to avoid that the cooking appliance is heated too hard when the cooking appliance starts to heat, so as to cause dry burning of the steam generator, after a cooking request of a user is obtained, the water pump may be controlled to pump a preset amount of water into the steam generator according to the cooking request, and the steam generator may be controlled to heat to a first preset temperature, so as to generate steam at a temperature close to a target temperature. The preset amount of water is selected according to the design of a pipeline of the steam generator, and the liquid level of the preset amount of water in the pipeline at least reaches one third of the diameter height of the pipeline. The target temperature is selected differently according to different properties of food materials, for example, the target temperature in the steamed stuffed bun steaming process is 98-102 ℃, and preferably 100 ℃. The first preset temperature is also determined according to the target temperature in the cooking request, and is generally 130-200 ℃; when the target temperature is set to be higher, the first preset temperature is selected to be higher temperature of 130-200 ℃, such as 180 ℃; when the target temperature is set to be lower, the first preset temperature is selected to be lower than 130-200 ℃, such as 130 ℃. In order to make the steam generator output high-temperature steam of 100 ℃, the steam generator needs to be controlled to be heated to 130 ℃ as in the embodiment.
