As shown in fig. 4 and 5, the lower case 30 is provided with a fresh air inlet 33 and at least one indoor air inlet 34. The fresh air inlet 33 is connected with a fresh air pipe so as to introduce fresh air flow from the outside. The fresh air inlets 33 are located on the rear wall of the lower casing 30, and the number of the indoor air inlets 34 is two, and the two indoor air inlets are respectively located on two lateral walls of the lower casing 30. The arrangement enables the centrifugal fan to suck fresh air flow and indoor air, thereby achieving the effect of killing two birds with one stone. In addition, a damper may be provided at the fresh air inlet 33 or the indoor air inlet 34 to control the opening and closing or the opening thereof, so as to adjust the air intake ratio of the fresh air flow and the indoor air.
As shown in fig. 4 and 5, the centrifugal fan may further include a filter screen for filtering the fresh air flow and the indoor air.
In some embodiments of the present invention, if the aforementioned second airflow is a purified airflow, a humidified airflow or a washing airflow, the functional module 32 may be disposed in front of the air inlet of the air inducing fan 31 in the lower casing 30, and the functional module 32 is a corresponding purified module, a humidified module or a washing module.
In some embodiments of the present invention, as shown in fig. 4, an air duct communicating with the second air outlet 21 is disposed in the second cylindrical shell 20 for guiding the non-heat-exchange air flow in the second cylindrical shell 20 to the second air outlet 21 more smoothly. The distance between the two side walls of the air duct is gradually reduced from back to front to form a gradually reduced shape. The tapered air duct can accelerate the air flow.
In some embodiments of the present invention, as shown in fig. 4, a vertical bar-shaped air duct connected to the second air outlet 21 is disposed in the second cylindrical shell 20, and the lower end of the air duct is the air inlet. A plurality of guide vanes 25 which are vertically arranged are arranged in the air duct, each guide vane 25 extends from front to back, and the distance between the front end and the back end of each guide vane 25, which is bent downwards to form a guide bending part, is larger when the guide vane 25 is closer to the upper position.
The second air flow flows from bottom to top, and after encountering each guide vane 25, is guided by the guide bending part, and gradually changes from top to front. Therefore, the diversion bent part plays a role in changing the direction of the airflow, so that the airflow is more smoothly turned, and the wind power loss is less. The diversion bent part and the rest part of the diversion sheet 25 are in fillet transition.
Further, considering that the second air flow enters the second casing 20 from the bottom of the second casing 20, the air output at the middle or upper part of the second air outlet 21 may be smaller. Therefore, the embodiment of the utility model provides a set up a plurality of water conservancy diversion pieces 25 of vertical arrangement in second column shell 20 very much to the position leans on the water conservancy diversion piece 25 earlier, the rear end distance more big more, makes second air outlet 21 more even at vertical everywhere air-out. Of course, the problem of small air output quantity in the middle or upper part of the second air outlet 21 can be fully utilized, so that the air mixing effect on the upper side is poor, and air can be supplied to places needing cold quantity, namely places needing no soft air.
In some embodiments of the present invention, the number of the first air guiding device and the number of the second air guiding device are three. While the induced draft fan 31 includes three cross flow fans 24.
