Problems solved by technology

[0003] However, there are generally differences between individuals in the actual production process of oxygen sensors, showing discreteness. At the same time, in kitchen appliances, when the oxygen concentration in the oven cavity is high, the detection results of the same model of oxygen sensors are consistent. Better, but when the oxygen concentration in the steamer cavity is low, the consistency of the detection results of the same model of oxygen sensors is poor, so the use of oxygen sensors for humidity detection will affect the consistency of product performance of steaming equipment

Embodiment 1

[0049] Embodiment 1 of the present invention provides an oxygen sensor calibration method, such as Figure 1-3 shown, including the following steps:

[0050] S1. Divide the oxygen concentration range in the medium into three areas in turn: the first area, the second area and the third area;

[0051] S2. Calculate specific constants of the oxygen sensors in the first area and the third area, respectively;

[0052] S3. Calculating the specific constants of the oxygen sensors in the second area based on the specific constants of the oxygen sensors in the first area and the third area, so as to calibrate the specific constants of the oxygen sensors in different oxygen concentration ranges.

[0053] In this way, by dividing the oxygen concentration range in the medium into three regions: the first region, the second region and the third region, and then calculating the oxygen sensor temperature of the first region and the third region respectively according to the current value an...

Embodiment 2

[0086] Such as Figure 4-5 As shown, Embodiment 2 of the present invention provides a steaming and roasting device for accurately detecting humidity using the oxygen sensor calibration method, including a steaming and roasting device body 1, an evaporator 2, a water tank 3, a temperature sensor 4 and an oxygen sensor 5, The water tank 3 is connected to the evaporator 2 through a water pump and a water pipe, and the evaporator 2 is connected to the steaming equipment body 1 through a steam pipeline, and a temperature sensor 4 and an oxygen sensor 5 are installed in the steaming equipment body 1;

[0087] According to the oxygen concentration range of the oxygen sensor 5, the steaming equipment body 1 is divided into three modes in sequence from low to high:

[0088] The first zone is a pure steam mode, and the specific constant of the oxygen sensor is the specific constant of the oxygen sensor in the first zone;

[0089] The second area is tender roast mode, and the specific c...

Abstract

The invention discloses an oxygen sensor calibration method and steaming and baking equipment applying the same and capable of accurately detecting humidity. The oxygen sensor calibration method comprises the following steps of S1, sequentially dividing an oxygen concentration range in a medium into three areas, namely a first area, a second area and a third area, S2, respectively calculating specific constants of the oxygen sensors in the first area and the third area, and S3, calculating specific constants of the oxygen sensors in the second area according to the specific constants of the oxygen sensors in the first area and the third area. The invention discloses an oxygen sensor calibration method. An oxygen concentration range in a medium is divided into three areas, the specific constant of the oxygen sensor in each area is calculated, and then the specific constants of the oxygen sensors in different oxygen concentration ranges are calibrated, so that the humidity is accuratelyregulated and controlled in combination with the corresponding relation between the oxygen concentration and the current value as well as the water vapor, the corresponding humidity is matched according to the food materials, and a better cooking effect is achieved.

Description

technical field [0001] The invention belongs to the technical field of steaming and baking equipment, and in particular relates to an oxygen sensor calibration method and a steaming and baking equipment for accurately detecting humidity using the method. Background technique [0002] The oxygen sensor is a device used to detect the oxygen concentration. Generally, the detected oxygen concentration is converted into a current signal and sent to the control device. The control device then converts the current signal into a digital signal and displays it on the controller. [0003] However, there are generally differences between individuals in the actual production process of oxygen sensors, showing discreteness. At the same time, in kitchen appliances, when the oxygen concentration in the oven cavity is high, the detection results of the same model of oxygen sensors are consistent. Better, but when the oxygen concentration in the steamer cavity is low, the consistency of the ...
