Detailed Description
The present invention is illustrated by the following examples, but the present invention is not limited to these examples. Modifications to the embodiments of the invention or equivalent substitutions of parts of technical features without departing from the spirit of the invention are intended to be covered by the scope of the claims of the invention.
The first embodiment is as follows: as shown in fig. 1 and 2, the present embodiment provides a control method of a steam cooking device, which includes an inner cavity 1, a humidifying device 2, a low temperature detection region 3, a first temperature sensor 4, a second temperature sensor 5, a third temperature sensor 6 and a controller, wherein a steam outlet of the humidifying device 2 is communicated with a steam inlet of the inner cavity 1, a steam outlet of the inner cavity 1 is communicated with a steam inlet of the low temperature detection region 3, the low temperature detection region 3 is used for cooling discharged high temperature steam, when parameters set by the system are fixed, a cooling degree of the high temperature steam by the low temperature detection region 3 is relatively fixed, the first temperature sensor 4 is arranged on the inner cavity 1 for detecting an inner cavity temperature, the second temperature sensor 5 is arranged on the low temperature detection region for detecting a low temperature, the third temperature sensor 6 is used for detecting a room temperature, and the controller is respectively connected with the humidifying device 2, The first temperature sensor 4, the second temperature sensor 5 and the third temperature sensor 6 are electrically connected, and the control method comprises the following steps:
s101, acquiring an inner cavity temperature T1, a low temperature detection zone temperature T2 and a room temperature T3;
s102, calculating and acquiring a humidity target value according to the inner cavity temperature T1, the low temperature detection zone temperature T2 and the room temperature T3;
and S103, controlling the humidifying device to work according to the humidity target value, specifically, controlling the humidifying device to work according to the humidity target value, so that the humidity of the inner cavity is between the upper limit of the humidity target value and the lower limit of the humidity target value.
An object of the present invention is to provide a control method of a steam cooking device, which has a simple structure and can improve the accuracy of humidity control.
Specifically, by establishing the relationship between the inner cavity temperature T1, the low temperature detection area temperature T2, the room temperature T3 and the inner cavity humidity, the humidity target value can be calculated and obtained after the inner cavity temperature T1, the low temperature detection area temperature T2 and the room temperature T3 are obtained, and the humidifying device is controlled to work according to the humidity target value, so that real-time detection and humidity control can be realized, and a better cooking effect is obtained. And the low-temperature humidity sensor is not needed to detect the humidity of the inner cavity, so that the defect of humidity detection by adopting the humidity sensor can be avoided.
In this embodiment, the humidity target value is obtained by calculation according to the following formula:
X＝[B-△T-(T3-C)]/A；
wherein X is a humidity target value, B is a temperature drop value of pure dry air, DeltaT is a difference value between an inner cavity temperature T1 and a low-temperature detection zone temperature T2, T3 is a room temperature, C is a preset room temperature in the pre-built model, and A is a straight slope of a temperature drop amplitude in the pre-built model. The humidity control device is reasonable and ingenious in design, can acquire a humidity target value according to the inner cavity temperature T1, the low temperature detection zone temperature T2 and the room temperature T3, is beneficial to realizing real-time detection and controlling humidity, and obtains a better cooking effect.
Further, the pre-established model is a relation model established on the basis of the relative humidity and the temperature under the condition of the preset room temperature.
The enthalpy value of the wet air is equal to the enthalpy value of the dry air and the water partial pressure saturation partial pressure, so that the temperature of the wet air is the same, the relative humidity is higher, the enthalpy value of the wet air is relatively higher, the relative humidity is higher after the same cooling capacity is carried out, the temperature drop difference is smaller, and the temperature drop amplitude is smaller.
Referring to fig. 3, fig. 3 shows a relationship model constructed based on relative humidity and temperature in a preset room temperature condition, where the preset room temperature condition is 20 ℃.
The relationship between the temperature reduction amplitude and the relative humidity when the preset room temperature is 20 ℃ is as follows:
△T＝B–A*X(％)；
where Δ T is T1-T2, X (%) is the relative humidity, and B is the temperature drop of pure dry air.
Taking into account the influence of the ambient temperature, in particular the seasonal influence, the room temperature T3 is introduced for correction, and then:
Δ T ═ B-a X (%) - (T3-20), where (T3-20) is the effect of room temperature on the model.
The above formula yields: x ═ B- Δ T- (T3-C) ]/a.
Of course, a relation model constructed based on the relative humidity and the temperature can be constructed under the condition that the preset room temperature is 5 ℃ and 35 ℃, and the controller can automatically match different preset models according to different seasons, for example, the preset model under the condition that the preset room temperature is 20 ℃ is matched in spring and autumn, the preset model under the condition that the preset room temperature is 5 ℃ is matched in winter, and the preset model under the condition that the preset room temperature is 35 ℃ is matched in summer.
