At present, in order to strengthen the air inlet effect of the integrated stove on the market, the mode of increasing the power of a motor or increasing the size of a fan system is adopted. The method of increasing the power of the motor can enable the motor to be in a high-load carrying state for a long time, the influence on the service life of the motor is large, the other method of increasing the size of the fan system increases the occupied space of the integrated stove, and the kitchen space which is not abundant is more crowded. The source tracing is carried out, and the improvement of the space utilization rate of the integrated cooker system can provide a solution for improving the air inlet effect of the integrated cooker. The main noise of the integrated cooker system is pneumatic noise, and the square of the pneumatic noise value is in positive correlation with the quintic power of the flow according to an empirical formula. Therefore, considering the air intake by the integrated stove bypass space, since the integrated stove bypass air volume is smaller than the main path air volume, the mathematical relationship shows that:
Q 5 ＞Q1 5 +Q2 5 +Q3 5 and Q = Q1+ Q2+ Q3
Wherein Q is the total flow, Q 1 Main air volume, Q 2 、Q 3 The bypass air quantity is adopted.
In this way the sum of the quintic powers of the flows will be reduced and theoretically the value of the squared noise will also be reduced, i.e. the noise value will be reduced.
