Description
Technical field
The present invention relates to air-conditioning technique, more particularly to a kind of mixed flow air-conditioning.
Background technology
On existing market, the air channel structure of common air-conditioning typically all by air inlet, centrifugal blower, vaporizer and goes out
Air port forms.Room air enters inside air-conditioning from air inlet, after centrifugal blower CENTRIFUGAL ACCELERATING, air
Carry out heat exchange through vaporizer, the air after heat exchange blows to interior by air outlet again.However, through air-out
Cool breeze temperature after mouth blowout is too low, not soft, blows to and can lead to user feel uncomfortable.
In order to solve above-mentioned technical problem, occur in that a kind of drain air-conditioning in prior art, it is in air conditioning exhausting
Introduce a little room air at mouthful, and it is mixed with the cool air after evaporator heat exchange, so that blowing
The wind going out is softer.However, this drain air-conditioning needs the air channel structure to air-conditioning and air outlet to carry out entirely
Face is transformed, and increased the cost of air-conditioning, and air-conditioning volume is excessive.
Content of the invention
In order to solve at least one defect of the prior art, the present inventor creatively proposes one
Kind structure is simple, lower-cost mixed flowing mode：Upstream by setting connection heat-exchanger rig inside air-conditioning
And the through path in the mixed flow space between heat-exchanger rig and air outlet, heat-exchanger rig upstream can be allowed
Air is directly flowed in mixed flow space by this through path.Thus, direction can be made under the driving of blower fan
The air portion lease making of air-conditioner air outlet flowing flows into be located at after crossing the heat exchange gap heat exchange of heat-exchanger rig itself and changes
The mixed flow space in thermal downstream, another part flows directly into mixed flow space through through path.Through heat exchange dress
Air after displacement heat and after through path mixes in mixed flow space without the air of heat exchange from going out
Air port is sent, thus the leaving air temp of air-conditioner air outlet, the comfort level of raising air-conditioning both can be relaxed and not right
Air conditioner structure makes excessive change, and structure is simple, and cost is relatively low.
However, it was found by the inventors of the present invention that air after heat-exchanger rig heat exchange with by through path
Larger without the temperature difference between the air of heat exchange, easily produce solidifying when two bursts of air streams mix in mixed flow space
Dew, affects the heat exchange efficiency of heat-exchanger rig or the performance of the blower fan within mixed flow air-conditioning or miscellaneous part is caused
Certain impact, and then affect the serviceability of whole mixed flow air-conditioning.
For this reason, one object of the present invention is intended to overcome at least one above-mentioned defect, provide a kind of comfort level
High, the mixed flow air-conditioning of better performances.
Another object of the present invention is intended to simplify mixed flow air-conditioning internal structure, reduces cost, reduces mixed flow empty
Adjust volume.
To achieve these goals, the present invention provides a kind of mixed flow air-conditioning, including：

Substantially tabular, to increase the contact area of air and heat-exchanger rig 50 further, improves further and changes
The thermal efficiency.
Further, leave gap between at least one end of heat-exchanger rig 50 and housing 10, between by being somebody's turn to do
Gap forms through path 30 between the upstream of heat-exchanger rig 50 and air outlet 12.Specifically, the present invention is real
Apply in example, between the lower end of heat-exchanger rig 50 and housing 10, leave the air allowing heat-exchanger rig 50 upstream
The gap directly passed through.It will be understood by those skilled in the art that in present invention others embodiment, heat exchange
The upper end of device 50, left or right also can leave and housing 10 between and allow heat-exchanger rig 50 upstream
The gap that air directly passes through.
In some embodiments of the invention, mixed flow air-conditioning 1 also includes at least one and is arranged in housing 10
Wind deflector.The gap that the quantity of wind deflector can be formed and the end of heat-exchanger rig 50 and housing 10 between
Quantity is identical, and that is, each gap is all correspondingly arranged on a wind deflector.Each wind deflector is by heat-exchanger rig 50
Upstream extend to air outlet 12 through corresponding gap, with this wind deflector and housing 10 and blower fan 20
Form through path 30 between wind path wall.In present invention others embodiment, each wind deflector is by it
Corresponding gap extends to air outlet 12, with the housing wall in this wind deflector and the neighbouring wind deflector of housing 10
Between formed through path 30.
That is, in certain embodiments of the present invention, wind deflector can be a bending plate, its lower end
Positioned at the upstream of heat-exchanger rig 50, its upper end extends to air outlet 12, and the centre of wind deflector passes through heat exchange to fill
Put the gap being formed between 50 and housing 10 and in the bending of this gap location.This wind deflector and housing 10 and wind
Form through path 30, the air inlet end of through path 30 is limited to blower fan between the wind path wall of machine 20
Between 20 wind path wall and the lower end of wind deflector.In present invention others embodiment, wind deflector can be
One flat board, its lower end can be adjacent to the gap being formed between heat-exchanger rig 50 and housing 10, and its upper end extends to
Air outlet 12.Form through path 30, directly between wind deflector and the housing wall of neighbouring wind deflector of housing 10
The air inlet end on road 30 is adjacent to this gap all.
Specifically, in the embodiment of the present invention, between the lower end of heat-exchanger rig 50 and housing 10, leave gap 13,
Mixed flow air-conditioning 1 may include the wind deflector 60 of a bending, and it passes through gap 13 by the upstream of heat-exchanger rig 50
Extend to air outlet 12.The section positioned at gap 13 downstream of wind deflector 60 can vertically extend,
That is, the front side board 10a formation of the section positioned at gap 13 downstream of wind deflector 60 and housing 10
Part of pass-though path 30 cross-sectional area everywhere is identical.The area positioned at gap 13 upstream of wind deflector 60
Section tilts to extend, and it is existed with the cross-sectional area of the part of pass-though path 30 of the wind path wall formation of blower fan 20
Flaring on its internal air-flow direction, to relax the speed air flow in through path 30, so that
Make the air without heat exchange in through path 30 preferably mixed with the air through heat exchange at air outlet 12
Close.
Further, wind deflector 60 has the curved section 61 of neighbouring air outlet 12, this curved section 61
Extended towards the outside of housing 10 by the inside of housing 10, so that air-out is flowed to by through path 30
Mouth 12 air and the air after heat-exchanger rig 50 heat exchange are mixed in the outside of air outlet 12.By
This, can make from the air of through path 30 and the air after heat-exchanger rig 50 heat exchange mixed when
The outside of air outlet 12 produces condensation, was both convenient to clean, and can avoid condensation along the inner surface of housing 10 again
It is downwardly towards blower fan 20 or miscellaneous part.
Fig. 4 is the schematic cross sectional views of mixed flow air-conditioning in accordance with another embodiment of the present invention, and Fig. 5 is basis
Another orientation schematic cross sectional views of the mixed flow air-conditioning of another embodiment of the present invention.The present invention other
