Device 2 and indoor fan 3 can be located in casing 1.Specifically, indoor fan 3 can be with when air conditioner indoor unit 100 works
By rotating to guide room air air-flow to enter in casing 1 by air inlet 1b, air draught is changed in casing 1 with interior
Hot device 2 exchanges heat to form heat exchange air-flow, and the exchanging air stream that then indoor fan 3 can guide heat exchange to complete is gone out by front side
Air port 1a discharge, heat exchange air-flow can circulation in space indoors, it is possible thereby to play the purpose of adjusting room temperature.
As shown in Figure 1-Figure 3, sliding door 4 can be located at the front side of casing 1 and sliding door 4 can be along the length side of casing 1
It is removable to (up and down direction as shown in Figure 1).Sliding door 4 is movable to the front of front side air outlet 1a to close front side outlet air
Mouth 1a, sliding door 4 are movable to the lower section of front side air outlet 1a to open front side air outlet 1a.Driving assembly 5 can be located at machine
On shell 1 and driving assembly 5 can cooperate with sliding door 4 to drive sliding door 4 to move up and down.
Specifically, driving assembly 5 can drive sliding door 4 to move in the up-down direction.When needs open front side outlet air
When mouth 1a, sliding door 4 can be driven to move down with respect to casing 1 for driving assembly 5 so that front side air outlet 1a is exposed, and exchange heat air-flow
It can be discharged by front side air outlet 1a.When needing to close front side air outlet 1a, driving assembly 5 can drive 4 phase of sliding door
Casing 1 is moved up, sliding door 4 can be moved to the front of front side air outlet 1a to block front side air outlet 1a.
It is understood that since sliding door 4 is located at the front side of casing 1, and driving assembly 5 can be located on casing 1,
It is possible thereby to which sliding door 4 is facilitated to be assembled with driving assembly 5 and casing 1, the assembly difficulty of sliding door 4 can be reduced.Moreover,
The outside that sliding door 4 is located at casing 1 can also increase the sliding stroke of sliding door 4, it is possible thereby to pass through the cunning of control sliding door 4
Dynamic stroke can promote the refrigeration and heating effect of air conditioner indoor unit 100 to adjust the air-out area of front side air outlet 1a.
For example, can accurately control sliding door 4 by driving assembly 5 since sliding door 4 has longer sliding stroke
Shift position.When the temperature difference between the ideal temperature required for the indoor environment temperature and user is larger, driving assembly 5 can be with
Driving sliding door 4 is moved down to fully open front side air outlet 1a, it is possible thereby to increase the air-out area of front side air outlet 1a,
The refrigeration and heating efficiency of air conditioner indoor unit 100 can be promoted.The ideal temperature required for indoor environment temperature and user
Between the temperature difference it is smaller when, driving assembly 5 sliding door 4 can be driven to be moved upward to setting position so that 4 part of sliding door hide
Gear front side air outlet 1a, it is possible thereby to reduce the air output of front side air outlet 1a, so as to so that indoor stablize keeps current temperature
Degree, can promote the usage comfort of user.
It is moving up and down by being arranged in the front side of casing 1 according to the air conditioner indoor unit 100 of the utility model embodiment

Product, and then the heat exchange efficiency of indoor heat exchanger 2 can be promoted.
As shown in figure 3, indoor fan 3 can be located at indoor heat exchanger 2 just in some embodiments of the utility model
Front, thus indoor fan 3 can guide air draught directly to blow to indoor heat exchanger 2 from back to front, can increase and act on
Air quantity on indoor heat exchanger 2, and then the heat exchange efficiency of indoor heat exchanger 2 can be promoted.
As shown in figure 3, indoor fan 3 can also include top blower 32 in some embodiments of the utility model, on
Portion's blower 32 can be located in the first air duct 11, it is possible thereby to increase the air output of indoor fan 3.For example, top blower 32 can
Think axial flow blower, the air-supply principle of axial flow blower is the outlet air of air inlet through hollow shaft axial direction.When top blower 32 works, top blower
32 can guide air draught can edge after the completion of direction circulation from back to front, air draught and the heat exchange of indoor heat exchanger 2
First air duct 11 and front side air outlet 1a discharge.As a result, when air conditioner indoor unit 100 works, top blower 32 and centrifugal blower
31 work at the same time, and can greatly increase the air output of indoor fan 3.
Of course, it should be understood that centrifugal blower 31 and top blower 32 can also be controlled individually.For example, can only control
Centrifugal blower 31 participates in air-supply, only can also participate in air-supply by control top blower 32, can also control 31 He of centrifugal blower simultaneously
Top blower 32 simultaneously participates in air-supply, can select to be arranged according to actual use demand.
For example, can control when the temperature difference between the ideal temperature required for the indoor environment temperature and user is larger
Centrifugal blower 31 and top blower 32 work at the same time, and centrifugal blower 31 can guide first strand of air draught successively extending wind-guiding
Circulation in portion 12b and annular air dam 12a, top blower 32 can guide second strand of air draught to exist along direction from back to front
Circulation in first air duct 11, first strand of air draught and second strand of air draught can be mixed in the front side of top blower 32
Stream may then pass through front side air outlet 1a discharge, it is possible thereby to increase the air output of indoor fan 3, and then can promote sky
Adjust the refrigeration and heating efficiency of indoor unit 100.The temperature difference between the ideal temperature required for indoor environment temperature and user
When smaller, it can choose in centrifugal blower 31 and top blower 32 one and participate individually in air-supply.
