Concrete meaning in the present invention.
Below in conjunction with attached drawing 1-6, the present invention is illustrated.
In one embodiment of the invention, a kind of air conditioning exhausting air mixing device is provided, including mix wind part, in the mixed wind part
It is provided with hollow chamber, air mixing channel, the air mixing channel and the hollow cavity are provided on the chamber wall of the hollow chamber
Room is connected.The outlet air that sky mentions device can be entered in the hollow chamber by the air mixing channel, and in the hollow chamber
Interior further mixing, is most discharged through air mixing channel afterwards, achievees the effect that air conditioner air-out is made to carry out mixed wind, is reducing blowing for outlet air
While wind sense, moreover it is possible to keep the temperature of outlet air uniform, keep outlet air more comfortable, improve the usage experience of user.
The mixed wind part includes at least one mixing wind tube 1, and the air mixing channel includes that leading on the mixing wind tube 1 is arranged in
Air holes 11, the mixed wind part carry out mixed wind to outlet air by the mixing wind tube 1.By the way that the mixing wind tube 1 is arranged, outlet air edge can be made
The round tube wall of the upper/lower terminal of the mixing wind tube 1 is discharged, and forms flow-disturbing effect to outlet air, can slightly increased wind speed, offset
It is decreased slightly as low wind speed because of air mixing channel turbulent flow, whole wind speed is remained unchanged, streams outlet air through entirety, hollow chamber
And flow-disturbing, the turbulent flow of ventilation hole 11 reach and are sufficiently mixed, and reduce air outlet temperature non-uniform phenomenon.
Further, the circumferential tube wall that the mixing wind tube 1 is set of the ventilation hole 11.
As shown in Figure 3,4, on the random tube wall for being distributed in the mixing wind tube 1 of the ventilation hole 11.The mixing wind tube 1
On be provided with the ventilation hole 11 of multiple diameter.A part of the outlet air of air conditioner is from the mixing wind tube 1 close to outlet air upstream
The ventilation hole 11 enter and mixed in the mixing wind tube 1, achieved the purpose that sufficiently to mix wind, reached leaving air temp
To uniform, mixed outlet air is discharged from ventilation hole 11 described in other, and converges with the outlet air through 1 upper and lower ends of mixing wind tube
Afterwards, it is discharged from the air outlet of the air conditioner, the mixing wind tube 1 of different-diameter further strengthens mixed wind effect.
Specifically, the diameter of the ventilation hole 11 is a quarter of 1 diameter of mixing wind tube to one, the mixed wind can be made
The wind speed of mixed wind effect and inlet and outlet in pipe 1 reaches best.
Another aspect of the present invention provides a kind of air conditioner, including air conditioning exhausting air mixing device as described above.
The mixed wind part is arranged in the exhaust apparatus of the air conditioner, and the outlet air of the exhaust apparatus can be along described mixed
The peripheral and described air mixing channel of wind part is discharged.The exhaust apparatus includes air-out passage, the mixed wind part setting it is described go out
In wind channel, the outlet air of the exhaust apparatus can be discharged along the peripheral and described air mixing channel of the mixed wind part.By making
The outlet air for stating exhaust apparatus can be discharged along the peripheral and described air mixing channel of the mixed wind part, further reduce blowing for outlet air
Wind sense, while outlet air path is also increased, also achieve the purpose that increasing outlet air mixes wind effect.
Further, the outlet air of the exhaust apparatus can bypass the mixed wind part along the upper/lower terminal of the mixed wind part
Blowout forms mixed wind to outlet air and acts on.
The mixed wind part has central axis, the length direction of the extending direction of the central axis and the air-out passage
It is identical.While the mixed wind part guarantee can be made to play the role of mixed wind to all outlet air, mixed wind number of packages amount is reduced, it is difficult to reduce installation
Degree.
Specifically, as shown in Figure 1, in the present embodiment, the quantity of the mixing wind tube 1 is one, and the air-out passage is lateral
Setting, the mixing wind tube 1 are horizontally installed in the air-out passage.
Specifically, the air conditioner in the present embodiment is hanging air conditioner 3, when air conditioning exhausting air mixing device setting exists
When in hanging air conditioner 3, the diameter of the mixing wind tube 1 is a quarter of the outlet air open height of the air-out passage to three points
One of, the mixing wind tube 1 can be made to reach best to the mixed wind effect of outlet air.The diameter of mixing wind tube 1 described in the present embodiment is institute
State the one third of the outlet air open height of air-out passage.
Further, it is provided with multiple mixed wind parts at the exhaust apparatus or the mixed wind part includes multiple described mixed
When air hose 1, the diameter of mixing wind tube 1 be may be the same or different, and the present embodiment is it is not limited here.
Specifically, the longitudinal section area of the mixing wind tube 1 in axial direction is not more than institute when the mixing wind tube 1 is one
State the one third of the outlet air open area of air-out passage, in the present embodiment, the longitudinal section area of the mixing wind tube 1 in axial direction
Equal to the one third of the outlet air open area of the air-out passage.
Optionally, when the mixing wind tube 1 is multiple, the sum of the longitudinal section area of the mixing wind tube 1 in axial direction is little
In the one third of the outlet air open area of the air-out passage.
As shown in Figure 5,6, the mixed wind part further includes connector 2, and the mixing wind tube 1 is arranged by the connector 2
In the air-out passage.The both ends of the mixing wind tube 1 are arranged in the connector 2, and the connector 2 includes pedestal 21 and pipe sleeve
22, the pedestal 21 is arranged on the side wall of the air-out passage, and the both ends of the mixing wind tube 1 are sheathed on the pipe sleeve respectively
22.The mixing wind tube 1 can be made more stable and can be detachably fixedly arranged on the side wall of the air-out passage.
Specifically, on the side wall that the connector 2 is fixed on air-out passage by way of bonding or screw.
As shown in Fig. 2, in another embodiment of the present invention, with a upper embodiment the difference is that, the air conditioner
For cabinet-type air conditioner 4 and when the mixed wind part includes 2 mixing wind tubes 1, when the air conditioning exhausting air mixing device is arranged in clothes closet
When in formula air conditioner 4, the diameter of the mixing wind tube 1 be the outlet air open height of the air-out passage 1 to eight/10th/
One.The mixing wind tube 1 can be made to reach best to the mixed wind effect of outlet air.The diameter of mixing wind tube 1 described in the present embodiment is described
/ 9th of the outlet air open height of air-out passage.
In another embodiment of the present invention, the difference is that, the mixing wind tube 1 can with two above-mentioned embodiments
The setting of rotation can rotate the mixing wind tube 1 in the air-out passage, convenient to adjust as needed to mixed wind effect
Section.
Specifically, the mixing wind tube 1 is rotatably coupled on the connector 2, the mixing wind tube 1 can also directly turn
On the side wall of the dynamic insertion air-out passage.
Specifically, the connector 2 and will be provided with washer between the mixing wind tube 1, the washer is for preventing outlet air
The mixing wind tube 1 is driven to rotate.
A kind of air conditioning exhausting air mixing device and air conditioner, beneficial effect provided in the embodiment of the present invention are, lead to
The mixed wind part of setting, hollow chamber and air mixing channel are crossed, so that the outlet air of air conditioner is changed to mixed wind outlet air by blow-through outlet air, is effectively reduced
