Heating function: in the fresh air mode or the purification mode, a heating mode can be set: the control module 19 starts the air inlet fan 11 and the exhaust fan 12, and starts heating in a fresh air mode, so that the working of the fresh air fan and the circulation of air are the same as those in the air purification function, and the temperature of outdoor air is increased when the outdoor air passes through the heater; when heated in the cleaning mode, the indoor air is warmed while passing through the heater, and the air flow path is the same as described above for the air cleaning function.
4. The air optimization function is as follows: in the fresh air mode or the purification mode, an optimization mode can be set: the anion generator emits a large amount of anions to enter the room along with the air flowing through the fresh air machine.
Example 7: FIG. 15 is a longitudinal sectional view of example 7. In this example, example 6 was mounted and operated. The difference lies in that: with fresh air door 6 setting in corresponding rain-proof cover 15 that introduces the wind channel, this kind of mode of setting can be convenient for maintain it to a certain extent. The principle and the usage of the fresh air function, the air purification function, the heating and air optimization function and the air flow path in this embodiment are the same as those in embodiment 6, and are not described herein again.
It should be understood that other variations or modifications may occur to those skilled in the art, in light of the present disclosure, such as: increase or reduce the utility model discloses a part component or change the appearance structure of new fan, also can partly or whole realize the utility model discloses an aim at, but all relate to introducing the wind channel and directly setting up the return ring door with the discharge wind channel, all regard as the utility model discloses a design, scheme and protection scope.
