Column.Installation cavity is defined in casing 110, and air inlet 111 and air outlet 112 are offered on its side wall.Air inlet 111
Extend along 110 short transverse of casing with air outlet 112 and is oppositely disposed on 110 side wall of casing.Heat exchanging part 120 is set to
Extend in installation cavity and along 110 short transverse of casing, installation cavity is divided into the air inlet area 113 that is connected to air inlet 111 with
And the blow zones 114 being connected to air outlet 112.Heat exchanging part 120 includes the heat exchange bracket 121 extended along 110 short transverse of casing
And it is mounted on the heat exchanger 122 inside heat exchange bracket 121, heat exchange bracket 121 is connected with the both ends of heat exchanger 122.Heat exchanging part
120 cross sectional shape in the horizontal plane can be circular arc, such as U-shaped or V-type, be come from facilitating heat exchanging part 120 can receive
The air inlet of different directions.Room air from air inlet 111 enter to air inlet area 113 after, remittance changed into heat exchanging part 120
Heat, the air after heat exchange are sucked into blow zones 114, are ultimately discharged into interior.
The setting of air intake blower fan 130 is configured to feed to heat exchange from the sucking outside air of air inlet 111 in air inlet area 113
Portion 120.By the way that air intake blower fan 130 is separately provided, intake can be not only improved significantly, but also right by air intake blower fan 130
Air acting is sucked, so that sucking air has stronger disturbance and flow velocity, is conducive to be promoted between air and heat exchanging part 120
Heat exchange efficiency.And be set as directly entering the wind from the air inlet 111 on side wall by air intake blower fan 130, it can guarantee as far as possible in original
Lesser change is done on organic type, and the purpose for increasing air quantity can be realized.Breeze fan 140 is arranged in blow zones 114, and matches
It is set to and the air to exchange heat through heat exchanging part 120 is discharged from air outlet 112.Breeze fan 140 in blow zones 114 is set, together
Sample plays the role of improving 120 heat exchange efficiency of heat exchanging part.140 pairs of the breeze fan air to exchange heat through heat exchanging part 120 carry out
Second of acting is formed the effect accelerated to multistage, is further mentioned by the cooperation of breeze fan 140 and air intake blower fan 130
The heat exchange efficiency of air velocity and heat exchanging part 120 is risen.
Vertical air-conditioner indoor unit 100 further includes blower rack 150, and blower rack 150 is fixedly connected with the top of heat exchanging part 120.
It is formed with connecting groove on the top of heat exchange bracket 121, blower rack 150 is formed with the connection knot to match with heat exchange bracket 121
Structure, so that blower rack 150 is fixedly connected with heat exchange bracket 121.Blower rack 150 extends towards air inlet area 113 for solid
Determine the interconnecting piece 151 of air intake blower fan 130, offer connecting hole on interconnecting piece 151, air intake blower fan 130 by connecting hole with connect
Portion 151 is fixedly connected.Blower rack 150 further includes the air dam 152 extended downwardly from interconnecting piece 151 along 110 short transverse of casing,
Air dam 152 is formed with the frame 153 for placing air intake blower fan 130.Air intake blower fan 130 is cross flow fan, high along casing 110
Degree direction is arranged in inside frame 153.By the way that the blower rack 150 being fixedly connected with heat exchange bracket 121 is arranged, by air intake blower fan
130 are mounted on air inlet area 113.On the one hand the fixed function for taking full advantage of heat exchange bracket 121, so that air intake blower fan 130 passes through
Blower rack 150 can be connected to heat exchanging part 120 relatively stablely, rather than be connected directly with casing 110, avoid when air inlet wind
Generated vibration damages casing 110 after the unlatching of machine 130.On the other hand it is also reasonably utilized inside casing 110
Space, so that air intake blower fan 130 may be mounted at apart from the closer position of heat exchanging part 120, so that blowing out from air intake blower fan 130
Higher wind air can rapidly enter to heat exchanging part 120 exchange heat, improve heat exchange efficiency.
Fig. 3 is the back schematic diagram of vertical air-conditioner indoor unit 100 according to an embodiment of the invention, and Fig. 4 is along Fig. 3
Cutting line A-A interception schematic cross sectional views.
Air dam 152 further includes the curved slab 154 for being used to form 130 spiral case of air intake blower fan, and curved slab 154 is constructed such that
Air intake blower fan 130 has towards the air inlet of air inlet 111 and towards the gas outlet of heat exchanging part 120.On air dam 152
The spiral case for directly forming air intake blower fan 130, so that the mounting structure of air intake blower fan 130 is more compact.Meanwhile utilizing curved slab
154 by the air inlet of air intake blower fan 130 towards air inlet 111 and gas outlet towards heat exchanging part 120 so that air intake blower fan 130
Disengaging wind path it is more reasonable.
In some alternative embodiments, air intake blower fan 130 can be two, the direction of rotation of two air intake blower fans 130
It is identical, and the gas outlet of two air intake blower fans 130 is respectively facing the not ipsilateral of heat exchanging part 120, so that blowing to heat exchanging part 120
Air can be more uniform covering heat exchanging part 120, improve overall heat exchange efficiency.
Those skilled in the art can be easy to think of, and air intake blower fan 130 can pass through and increase air intake blower fan to be multiple
130 quantity, to improve the whole intake of vertical air-conditioner indoor unit 100.By multiple air intake blower fans 130 along the circumferential direction of casing 110
Direction is set gradually, and the space utilization in installation cavity can be made more reasonable.
Breeze fan 140 is a cross flow fan along 110 short transverse of casing arrangement, is had whole for one from top to bottom
The tubular wine wheel of body.The air inlet direction of breeze fan 140 is opposite with the gas outlet of air intake blower fan 130, and air intake blower fan 130 with give
The length of wind blower 140 is identical or the length of air intake blower fan 130 is greater than the length of breeze fan 140, to guarantee air intake blower fan
Breeze fan 140 can be completely covered in the air of 130 blowouts.
The vertical air-conditioner indoor unit 100 of the present embodiment installs air intake blower fan 130 inside casing 110, is used for casing
Air outside 110 quickly sucks and feeds to heat exchanging part 120, and then increases the intake of breeze fan 140.By adding direction
The air intake blower fan 130 of side wall air inlet 111, reach only done on the basis of existing casing 110 it is lesser change just effectively mention
The intake of high vertical air conditioner indoor unit 100 and the purpose of intake velocity meet the needs of user is to Wind Volume fast regulating temperature.
Further, the vertical air-conditioner indoor unit 100 of the present embodiment, by the way that blower rack 150 is arranged inside casing 110,
Newly-increased air intake blower fan 130 is fixed between heat exchanging part 120 and air inlet 111, while forming air inlet wind on blower rack 150
The spiral case of machine 130.The space structure inside casing 110 is not only rationally utilized, so that vertical air-conditioner indoor unit 100 is tied on the whole
Structure is compact, and newly-increased air intake blower fan 130 is upwardly formed with original breeze fan 140 in air intake and is preferably matched
It closes, improves the consistency of whole air inlet wind path.
So far, although those skilled in the art will appreciate that present invention has been shown and described in detail herein multiple shows
Example property embodiment still without departing from the spirit and scope of the present invention, still can according to the present disclosure directly
