[0008] In the above two delay stages, since the ambient temperature is lower than the internal temperature of the steaming equipment, although the absolute humidity inside the steaming equipment is already high, the maximum value of the absolute humidity that the sensor can detect is low, so the sensor cannot correctly reflect the temperature of the steaming equipment. The absolute humidity in the baking equipment needs to go through a long delay, and the absolute humidity value can only be detected correctly after the surrounding environment of the sensor is heated up to the water vapor temperature

The invention discloses a control method of a steaming and baking equipment with an external humidity detection device. The control method includes the following steps: starting the steaming and baking equipment to enter the preheating stage, controlling the opening of the inner heater, the outer heater and the fan; When the humidity detection device detects that the ambient temperature reaches the first preset temperature, the heater outside the cavity is controlled to turn off; when the inner cavity temperature reaches the second preset temperature, the preheating stage ends and the cooking stage is completed, and the absolute humidity is detected by the humidity detection device ; It can improve the accuracy of detecting the absolute humidity value in the steaming and baking equipment.
Description
technical field [0001] The invention relates to the technical field of cooking equipment, in particular to a control method of a steaming and roasting equipment with an external humidity detection device. Background technique [0002] In the related art, the absolute humidity sensor is an electronic device for detecting the water vapor content per unit volume in the air, usually a dual NTC type or an oxygen detection type sensor. Conditions for correct use of this type of sensor: [0003] 1. Place the sensor in the flowing air; [0004] 2. Avoid condensation on the sensor body. [0005] If this type of sensor is used to detect the humidity in the steaming equipment, it is appropriate to place the sensor at the outer exhaust port of the steaming equipment. However, absolute humidity is greatly affected by temperature. The higher the temperature, the greater the water vapor saturation per unit volume of air, and the lower the temperature, the smaller the water vapor saturat...
