In order further to improve the effect of anti-bias current amount, described three air outlets all are positioned at supporting base near a side of described suction port.Similarly, only exist in the valve under the situation of the freezing cold air of part in dynamoelectric switching valve generation slight inclination, because the spacing between air outlet and the suction port is less, thereby can further guarantee this part cold air can be equably from two air outlets or three air outlets flow out, the probability that bias current amount phenomenon takes place is littler.
Compared with prior art, advantage of the present utility model is: become its bottom opening greater than the structure of bottom opening by the base designs with dynamoelectric switching valve, and supporting base and air outlet are positioned at the bottom opening place, like this, slight inclination angle takes place and have only in the valve under the situation of the freezing cold air of part at dynamoelectric switching valve, can guarantee preferably that also cold air can flow out from the air outlet of supporting base equably, prevents bias current amount phenomenon.
