In some embodiments of the invention, multiple calm sense grades include first grade to N grades, from first grade to N Shelves, calm sense distance are gradually increased, that is to say, that the calm sense distance < third gear of first grade of calm sense distance < second gear N grades of < ... < of calm sense distance of calm sense distance.Thus, it is possible to keep the control logic of calm sense grade simpler bright , facilitate the actual use of user.For example, x calm sense grades may include first grade to N grades, x can be equal to N, then often A calm sense grade respectively corresponds a gear, calm sense distance L1、L2、…、LxFirst grade to N grades can be respectively corresponded, nothing Wind sense distance is gradually increased, L1< L2< ... < LxThen.Wherein, N can be natural number greater than 1, for example, N can for 2 or 5, Or 6 etc..
It is understood that the set-up modes of multiple calm sense grades are not limited to that, for example, from first grade to N Shelves, calm sense distance can also be gradually reduced.
Specifically, in N number of gear, the revolving speed of the second fan assembly 3 is remained unchanged.That is, different calm Feel in grade, the output revolving speed of the second fan assembly 3 remains unchanged, i.e., the second fan assembly 3 keeps identical in N number of gear Revolving speed, can be by the revolving speed of the first blower 21 of adjusting and/or the second blower 22 to realize the switching of gear, to realize calm Feel the switching of grade.Thus, it is possible to keep the control method of air conditioner 100 simpler, it is further simplified the control of air conditioner 100 Logic, to promote the control efficiency of air conditioner 100.
In some embodiments of the invention, on air-flow direction, the second blower 22 is located under the first blower 21 Trip, stops operating controlling the first blower 21 in each of (M < N) calm sense grade from first grade to M grades, wherein from first Shelves are into M grades of M gear, and gear is higher, and the revolving speed of the second blower 22 is higher.For example, as shown in figure 5 and figure 7, working as air-conditioning When device 100 is in calm sense mode, if the calm sense grade of air conditioner 100 is between first grade to M grades, the first wind Machine 21 does not export revolving speed, i.e., in each gear from first grade to M grades, the revolving speed of the first blower 21 is 0.If desired first Shelves are to when adjusting calm sense grade between M grades, the revolving speed and nothing of adjustable second blower 22 and/or the second fan assembly 3 The revolving speed of the first blower 21 need to be adjusted to realize that calm sense grade switches between first grade to M grades；Wherein, M can be with For the natural number greater than 0；As M=1, then the first blower 21 stops operating in first grade and the second blower 22 rotates, when M >=2 When, then the first blower 21 stops operating and revolving speed the mentioning with gear of the second blower 22 in first grade to M grades of multiple gears It rises and increases, ensure that the air supplying distance of high tap position farther out, so that it is biggish to ensure that the calm sense grade of high tap position may be implemented Calm sense distance.
It should be noted that " high tap position " is relative concept." air supplying distance " can be understood as calm sensillary area domain and casing 1 Between maximum distance.
For example, that is, multiple calm sense grades may include first grade to eighth speed, if air conditioner when N=8, M=4 When 100100 calm sense grade is in first grade between fourth speed, the first blower 21 does not export revolving speed.When air conditioner 100 exists First grade to when being adjusted between fourth speed, can only adjusting the output revolving speed of the second blower 22 and without adjusting the first wind The output revolving speed of machine 21.Wherein, in first grade of four gear to fourth speed, the gear of calm sense is higher, the second blower 22 Revolving speed is higher.As a result, by above-mentioned setting, the control mode of air conditioner 100 can simplify, reduce being designed to for air conditioner 100 This.Certainly, the value of M, N are without being limited thereto.
Further, the rotation of the first blower 21 in each gear of (M+1 < N), is being controlled from M+1 grades to N grades, That is the output revolving speed of the first blower 21 is not 0, i.e., from M+1 grades in each gear from M+1 grades to N grades Into N grades of each gear, the first blower 21 and the second blower 22 can be rotated, to be further ensured that the air-supply of high tap position Distance, so that biggish calm sense distance may be implemented in high tap position.Wherein, in each gear from M+1 grades to N grades, The output revolving speed that the first blower 21 can be made to be kept fixed can also be such that the speed change of the first blower 21 rotates.
Optionally, in each gear from M+1 grades to N grades, the revolving speed of the second blower 22 is all larger than the first blower 21 revolving speed.It is understood that due in each gear from M+1 grades to N grades, the first blower 21 and the second blower 22 rotations simultaneously are simultaneously blown towards the first air outlet 11a.As shown in figure 5 and figure 7, the second blower 22 can be located at the first blower 21 downstream side, the revolving speed by the way that the second blower 22 is arranged are greater than the revolving speed of the first blower 21, and the second blower 22 can give first Blower 21, which applies driving force, can promote the air-supply of the first fan assembly 2 it is possible thereby to reduce the windage loss of the first fan assembly 2 Effect.Certainly, in each gear from M+1 grades to N grades, the output revolving speed of the first blower 21 and the second blower 22 can also be with It is identical.
In some embodiments of the invention, in multiple gears from M+1 grades to N grades, gear is higher, the The revolving speed of two blowers 22 is higher.As a result, with it is calm sense grade raising, the second blower 22 can by promoted output revolving speed with The cooperation of first blower 21 guarantees bigger calm sense distance to realize farther air supplying distance.For example, as shown in figs. 4 and 7, First fan assembly 2 is located at the top of the second fan assembly 3, in multiple gears from M+1 grades to N grades, the first blower The air supplying distance of component 2 can be greater than the air supplying distance of the second fan assembly 3, and the air draught being located above can be empty indoors Interior slowly circulation from top to down, it is possible thereby to keep indoor Temperature Distribution more uniform.Moreover, underlying air draught Can down to lower and upper slow circulation and can above air draught mixed, can be with it is possible thereby to play the role of mixed flow Keep indoor Temperature Distribution more uniform, the refrigeration and heating effect of air conditioner 100 can be promoted.
