Fig. 4 shows another air supply pattern of indoor unit 10, as shown in figure 4, the outer plate section 13 in left side turns to the 5th
Position, the inner plate section 14 in left side turn to the 6th position, and referring to Fig. 2, the 6th position can be identical as the second position, are in the 5th
The outer plate section 13 set turns to maximum position, that is to say, outer plate section 13 is swung down to opening amplitude maximum, corresponding maximum air-supply
State, the outer plate section 13 in the 5th position and the inner plate section 14 in the 6th position are by the air-flow on the left of air outlet to indoor unit
10 front lower place guidance, so that the wind direction front lower place of left area is blown out, so that the people for being located at 10 lower left of indoor unit can experience
To blowing, cooling rate is fast.And the outer plate section 13 on right side turns to the 7th position, the inner plate section 14 on right side turns to the 8th
It sets, the outer plate section 13 in the 7th position and the inner plate section 14 in 8 positions are in upward state, outer under the state
Plate section 13 and inner plate section 14 boot up the wind of air outlet right area, so that the air-flow of right area is blown out upwards, so that
People positioned at 10 lower right of indoor unit cannot experience blowing, increase body-sensing comfort, so that 10 left and right sides region of indoor unit
With different air supply patterns, the usage experience of user is promoted.
As previously mentioned, Fig. 3 and Fig. 4 illustrate only two kinds of air supply patterns of indoor unit 10, it is possible to understand that, due to outer wind-guiding
Each outer plate section 13 of plate and each inner plate section 14 of internal air baffle can independent control, independently rotated, it is therefore, each
The turned position of outer plate section 13 and the turned position of each inner plate section 14 can be it is a variety of, for example, if outer wind deflector includes two
A outer plate section 13, internal air baffle includes two inner plate sections 14, under air-conditioning heating mode, outer plate section 13 and inner plate section positioned at left side
14 turned position can realize that air outlet left area is upward on the wind direction of air outlet left area, guide downwards or forward
Blowing is put down forward in blowing, downwards blowing；Similarly, can will go out positioned at the outer plate section 13 on right side and the turned position of inner plate section 14
On the wind direction of air port right area, downwards or guide forward, realize air outlet right area to up-draught, downwards blowing or forward
Flat blowing.
In some embodiments, be provided at the upper wall in air duct it is multiple lead wind pendulum leaf (not shown), it is multiple to lead wind pendulum leaf edge
Transverse direction arrangement, and be configured to adjust to rotation the lateral air-out direction of air outlet.Wind pendulum leaf is led in existing air conditioning chamber
Using extensively in machine 10, details are not described herein its specific structure.
In traditional indoor unit, generally internal air baffle slewing area will not turn to the inside in air duct, lead all in air duct
Wind effect is limited.And in some embodiments of the utility model, each inner plate body can be configured to forward upward and turn to wind
The outside in road, so that the wind-guiding effect of internal air baffle is obvious, is more conducive to internal air baffle to increase the slewing area of inner plate body
The wind-guiding that different mode is realized in cooperation is carried out with outer wind deflector.
The cock arm 15 of each inner plate body can be formed with the evacuation notch (not shown) of evacuation air outlet top edge, work as inner panel
When body forward upward turns to the outside in air duct, evacuation notch can be abutted with the top edge of air outlet, so that inner plate body and outlet air
The top edge of mouth is preferably bonded, and eliminates the gap of inner plate body and 11 front surface of shell, and reduction is leaked out, and promotes wind effect.
When outer plate body 13a turns to closed position, the top edge of outer plate body 13a is denoted as to the first edge of outer plate body 13a,
The lower edge of outer plate body 13a is denoted as to the second edge of outer plate body 13a, in some embodiments, is faced on the inside of outer plate body 13a
The position of nearly second edge is formed with the barrier rib (not shown) for being used to obstruct air-flow of outside plate body 13a interior direction protrusion.
In cooling mode, when outer plate body 13a participates in wind-guiding, cold wind is blocked muscle and blocks, and changes direction, so that cold wind is along outer plate body
13a is blown out forward, and cold wind is avoided to blow out backward, forms condensed water in the posterior edges of outer plate body 13a.
The air conditioner indoor unit 10 of the present embodiment, outer wind deflector include at least two outer plate sections being horizontally sequentially distributed
13, each outer plate section 13 is rotatablely arranged on shell 11, thus horizontal using at least two outer plate section 13 adjustment air outlet
The air-out direction of different zones on direction meets the diversified demand of user to increase the air supply pattern of indoor unit 10.
Further, in the air conditioner indoor unit 10 of the present embodiment, internal air baffle includes horizontally being sequentially distributed at least
Two inner plate sections 14, each inner plate section 14 are rotatablely arranged on shell 10, so that inner plate section 14 and outer plate section 13 can quilts
It independently controls and rotates, to realize more different air-supply moulds of indoor unit by the cooperation of inner plate section 14 and outer plate section 13
Formula increases user experience.
So far, although those skilled in the art will appreciate that the more of the utility model have been shown and described in detail herein
A exemplary embodiment still, still can be according to the utility model public affairs in the case where not departing from the spirit and scope of the utility model
The content opened directly determines or derives many other variations or modifications for meeting the utility model principle.Therefore, this is practical new
