Referring to fig. 1 to 5, an embodiment of the present disclosure provides an air duct assembly 100, including: the air conditioner comprises a shell 200, wherein an air inlet cavity 210, a first air outlet cavity 220 and a second air outlet cavity 230 are formed inside the shell 200, the first air outlet cavity 220 and the second air outlet cavity 230 are respectively positioned at two sides of the air inlet cavity 210, and the air inlet cavity 210 is respectively communicated with the first air outlet cavity 220 and the second air outlet cavity 230; an air inlet 211, a first air outlet 221 and a second air outlet 231 are formed in the shell 200, the air inlet 211 is communicated with the air inlet cavity 210, the first air outlet 221 is communicated with the first air outlet cavity 220, and the second air outlet 231 is communicated with the second air outlet cavity 230; the direction of the airflow flowing into the first air outlet cavity 220 from the air inlet cavity 210 is collinear with the direction of the airflow flowing into the second air outlet cavity 230; the centrifugal wind wheel 300 is arranged in the air inlet cavity 210, and the air inlet surface of the centrifugal wind wheel 300 is parallel to the plane of the air inlet 211; the heat exchanger 400, the heat exchanger 400 covers on the air intake 211.

It should be noted that the air duct assembly 100 provided in the embodiment of the present application is particularly suitable for a window type air conditioner (not shown in the drawings), and optionally, the air duct assembly 100 provided in the embodiment of the present application is also suitable for a wall-mounted air conditioner or a cabinet type air conditioner, etc.; the air inlet surface of the centrifugal wind wheel 300 is a plane perpendicular to the rotation axis of the centrifugal wind wheel 300, air flow enters the centrifugal wind wheel 300 from the air inlet surface, the air inlet surface of the centrifugal wind wheel is parallel to the plane of the air inlet 211, that is, the air inlet surface of the centrifugal wind wheel 300 is arranged right opposite to the air inlet 211, so that the air flow can directly flow into the centrifugal wind wheel 300 from the air inlet 211.

Through arranging the air inlet cavity 210 in the shell 200, the centrifugal wind wheel 300 is arranged in the air inlet cavity 210, and the air inlet surface of the centrifugal wind wheel 300 is arranged to be parallel to the plane of the air inlet 211, namely, the air flow flows to the air inlet surface along the extending direction of the air inlet cavity 210 through the air inlet 211 and then is thrown out from the periphery of the centrifugal wind wheel 300; in addition, a first air outlet cavity 220, an air inlet cavity 210 and a second air outlet cavity 230 which are sequentially communicated are formed in the casing 200, and the three air cavities are approximately arranged on the same horizontal plane, so that the plane of the air outlet direction of the centrifugal wind wheel 300 is coplanar with the plane of the three air cavities, and further, the air flow thrown out from the two sides of the centrifugal wind wheel 300 can enter the first air outlet cavity 220 and the second air outlet cavity 230 and flow out through the first air outlet 221 and the second air outlet 231, the turning of the air flow in the air inlet cavity 210 is avoided, and further, the air flow loss caused by the impact of the air flow in the air inlet cavity 210 on the inner wall surface is reduced, and the air flow can uniformly flow into the first air outlet cavity 220 and the second air outlet cavity 230, so that the air outlet amount of the air duct assembly 100 is more uniform.

In addition, in the prior art, the air duct assembly 100 of the cross-flow wind wheel is adopted, and the air output on the two sides of the cross-flow wind wheel is smaller than that on the middle part, so that the air output on the two sides of the air outlet of the air duct assembly 100 is smaller. And owing to set up centrifugal wind wheel 300 in this application, and the air inlet face of centrifugal wind wheel 300 is on a parallel with air intake 211 place plane, and then can set up first air outlet 221 and second air outlet 231 in the both sides of air intake 211 for the air current is from the both sides air-out of wind channel subassembly 100, makes indoor air distribution more even.

Specifically, the housing 200 is rectangular, so as to be better adapted to a window air conditioner; and the air inlet cavity 210, the first air outlet cavity 220 and the second air outlet cavity 230 are all cubic, so that the three air cavities arranged side by side can utilize the internal space of the rectangular housing 200 to a greater extent, and the space utilization rate of the internal cavity of the housing 200 is improved.

Furthermore, the joints of the adjacent inner side walls of the air inlet cavity 210, the first air outlet cavity 220 and the second air outlet cavity 230 are formed by enclosure and are chamfered, so that the interiors of the three air outlet cavities are smoother, the impact loss of air flow flowing in the three cavities is effectively reduced, and the air supply quantity is improved.

Further, in other embodiments, the air inlet chamber 210, the first air outlet chamber 220 and the second air outlet chamber 230 may also be cylindrical chambers, which are not limited herein.

Referring to fig. 1, 2 and 5, in some embodiments, the air duct assembly 100 further includes an air baffle 500, where the air baffle 500 is disposed on a side of the heat exchanger 400 facing the air outlet; the wind deflector 500 includes a first wind deflector portion 510 and a second wind deflector portion 520, the first wind deflector portion 510 covers a part of the first wind outlet 221, and the second wind deflector portion 520 covers a part of the second wind outlet 231; the two ends of the heat exchanger 400 extend away from the air inlet 211 and cover the first wind blocking portion 510 and the second wind blocking portion 520.

It can be understood that, since the air inlet cavity 210, the first air outlet cavity 220 and the second air outlet cavity 230 are arranged side by side, the air inlet 211 occupies only about one third of the front panel space of the air duct assembly 100, so that the area of the heat exchanger 400 only covering the air inlet 211 is smaller, which results in lower heat exchange efficiency of the air duct assembly 100.

It should be noted that, in the process that the air inside the room enters the air inlet cavity 210 through the air inlet 211, the air flow inside the room gradually decreases into the air inlet 211 in a "trumpet shape".

It should be noted that, in order to maximize the utilization of the internal space of the housing 200, the areas of the first air outlet 221 and the second air outlet 231 in the embodiment of the present application are relatively large, which may reduce the speed of the air flow flowing out through the first air outlet 221 and the second air outlet 231, thereby reducing the diffusion radiation range of the air outlet of the air duct assembly 100.

The wind shield 500 is arranged, the first wind shield part 510 covers a part of the first wind outlet 221 and the second wind shield part 520 covers a part of the second wind outlet 231, and two ends of the heat exchanger 400 extend to cover the first wind shield part 510 and the second wind shield part 520; on the one hand, under the condition of the same air output volume in the first air outlet cavity 220, the first wind blocking part 510 reduces the area of the first air outlet 221, so as to increase the air flow velocity passing through the first air outlet 221, and further expand the diffusion radiation range of the air output from the first air outlet 221; on the other hand, since the first wind blocking portion 510 is disposed between the heat exchanger 400 and the first wind outlet cavity 220, it avoids mutual interference between the wind outlet flow in the first wind outlet cavity 220 and the wind inlet flow passing through the wind inlet cavity 210 of the heat exchanger 400, and further increases the wind output of the first wind outlet 221; the second wind blocking part 520 achieves the same effects and principles as the first wind blocking part 510 described above, and will not be described herein too much.

In particular, the first wind blocking portion 510 and the second wind blocking portion 520 are respectively disposed at two sides of the air inlet 211, and two ends of the heat exchanger 400 extend to cover the first wind blocking portion 510 and the second wind blocking portion 520, so that a heat exchange flow channel (not shown in the figure) is formed between the first wind blocking portion 510 and the heat exchanger 400 and between the second wind blocking portion 520 and the heat exchanger 400, and extends to the air inlet 211, so that the air flow in a trumpet shape at the indoor side is matched with the shape of the heat exchanger 400; and then the air current in the air current center that indoor side is "loudspeaker form" can directly flow into air inlet chamber 210, and the air current of both sides edge can get into air inlet chamber 210 through the heat transfer runner. It can improve the area of contact of indoor side air current and heat exchanger 400, has prolonged the time of part air current through heat exchanger 400, has improved heat exchanger 400's the effect of trading.

Specifically, wind deflector 500 further includes a main plate 540, and first and second

wind blocking portions

510 and 520 are disposed on main plate 540.

In some embodiments, the first wind blocking part 510 is disposed near a lower side of the first wind outlet 221, and the second wind blocking part 520 is disposed near a lower side of the second wind outlet 231.

It can be understood that the window type air conditioner usually only starts the cooling mode most of the time, and the cold air is easy to sink, so the person skilled in the art usually chooses to set the air outlet of the air conditioner upward when the cooling mode is started to improve the cooling effect.

Through the first wind-blocking portion 510 that is close to the downside arrangement of first air outlet 221 and the second wind-blocking portion 520 that is close to the downside of second air outlet 231 for remaining portion first air outlet 221 and second air outlet 231 are located the upside of heat exchanger 400, and then make the air-out air current orientation of wind channel subassembly 100 blow off, make the cold air that blows off through the window air conditioner distribute more evenly at the indoor side.

In some embodiments, one fresh air channel 240 is formed at each of the lower sides of the two ends of the housing 200, and the fresh air outlets 241 of the two fresh air channels 240 are respectively disposed at the two sides of the heat exchanger 400.

It should be noted that one end of the fresh air channel 240 extends to the outdoor side, and the other end extends to the indoor side; wherein, the one end that new trend runner 240 is located the outdoor side is formed with the new trend entry, and the one end that is located the indoor side is formed with new trend export 241.

In addition, as described above, since the first wind blocking portion 510, the second wind blocking portion 520 and the heat exchanger 400 form a heat exchange flow channel therebetween, the fresh air flow channel 240 is disposed at the lower side of the two ends of the casing 200, and the fresh air outlet 241 is disposed at the side of the heat exchanger 400, under the action of the negative pressure in the air inlet chamber 210, the air flow outside the room can enter the heat exchange flow channel through the fresh air outlet 241, and finally enter the air inlet chamber 210 through the air inlet 211.

Therefore, the air duct assembly 100 can suck outdoor fresh air and send the fresh air to the indoor side, and the air quality of air supplied by the air duct assembly 100 is improved; and the new trend is through heat exchanger 400, and heat exchanger 400 can adjust the temperature of new trend, and then when heat exchange module opened the new trend mode, has reduced the fluctuation by a wide margin of indoor difference in temperature, and user experience is better.

Further, in other embodiments, an air valve (not shown in the figure) may be disposed in the fresh air flow channel 240 for opening and closing the fresh air flow channel 240, so that a user may open the fresh air mode according to needs.

Referring to fig. 1, 2 and 4, in some embodiments, the heat exchanger 400 includes a first sub-portion 410 and two second sub-portions 420, the two second sub-portions 420 being respectively disposed at two sides of the first sub-portion; the fins of the first sub-portion 410 are perpendicular to the plane of the air inlet 211, and the fins of the second sub-portion 420 are perpendicular to the plane of the fresh air outlet 241.

It should be noted that, because the fresh air outlet 241 is disposed at the lower sides of the two ends of the casing 200, the plane where the fresh air outlet 241 is located is perpendicular to the plane where the air inlet 211 is located, that is, the air outlet direction of the fresh air outlet 241 is perpendicular to the air inlet direction of the air inlet 211.

It should be noted that the heat exchanger 400 generally includes a condenser tube and a fin, heat in the condenser tube is transferred to the fin, the fin radiates heat to ambient air, and the air flow passes through the surface of the fin and then exchanges heat with the ambient air, thereby changing the temperature of the air flow passing through the heat exchanger 400.

Therefore, by arranging the first sub-part 410 and the second sub-part 420, and arranging the second sub-part 420 corresponding to the fresh air outlet 241, and arranging the first sub-part 410 corresponding to the air inlet 211; most of indoor return air enters the air inlet cavity 210 through the first sub-portion 410, so that the fins of the first sub-portion 410 positioned in the middle are perpendicular to the air inlet 211, the heat exchange effect of the indoor return air can be improved, and the fins of the second sub-portions 420 positioned on two sides are perpendicular to the fresh air outlet 241, and the heat exchange effect of the fresh air can be improved.

Preferably, the first sub-section 410 and/or the second sub-section 420 are parallel flow heat exchangers.

The fins of the parallel flow heat exchanger are V-shaped, so that the heat exchange area of the parallel flow heat exchanger can be increased, and the structural strength of the parallel flow heat exchanger can be improved according to the triangular stability principle; in addition, compared with other types of fins, the V-shaped fins can better break up the limited boundary of air, promote the air flow stroke to be lengthened, and improve the heat exchange effect of the heat exchanger 400.

Further, in other embodiments, the first sub-portion 410 and/or the second sub-portion 420 may also be a tooth heat exchanger, etc., and are not limited herein.

In some embodiments, the heat exchanger 400 includes a heat exchanging portion 430 and a leakage preventing portion 440, the heat exchanging portion 430 having a rectangular plate shape, the leakage preventing portion 440 being disposed at an upper side of the heat exchanging portion 430; the heat exchanging part 430 covers the first wind blocking part 510, the second wind blocking part 520, and a portion of the wind inlet 211, and the leakage preventing part 440 covers the remaining portion of the wind inlet 211.

It is understood that the first wind blocking part 510 and the second wind blocking part 520 are preferably disposed near one side edge.

Therefore, in order to reduce the interference between the intake airflow of the heat exchanger 400 at the intake vent 211 and the exhaust airflow at the first outlet 221 and the second outlet 231, the heat exchanging portion 430 is configured as a rectangular plate, the heat exchanging portion 430 only covers a part of the intake vent 211, and the leakage preventing portion 440 is configured to cover the remaining intake vent 211; on the one hand, can simplify the structure of heat transfer portion 430, on the other hand, the regional one side that is close to casing 200 of whole of the air inlet air current place of heat exchanger 400 for the air inlet air current place of heat exchanger 400 sets up and does not have crisscross region with the regional interval of air outlet air current place, has effectively avoided the mutual interference of air inlet air current and air outlet air current of heat exchanger 400, has improved the air output of wind channel subassembly 100.

Further, in other embodiments, the heat exchanging portion 430 of the heat exchanger 400 has a shape of "convex", that is, the heat exchanging portion 430 completely covers the air inlet 211 without providing the leakage preventing portion 440, which is not excessively limited herein.

In some embodiments, the leakage preventing part 440 is detachably connected to the heat exchanging part 430.

By detachably connecting the leakage preventing portion 440 with the heat exchanging portion 430, the heat exchanger 400 can be disassembled into the heat exchanging portion 430 and the leakage preventing portion 440, which are both rectangular plate-shaped, so that the structures of the heat exchanging portion 430 and the leakage preventing portion 440 are simplified, and the assembly and installation of the heat exchanger 400 are facilitated.

In some embodiments, a flow guide groove 530 is formed on a surface of the wind deflector 500 on a side facing the heat exchanger 400.

It can be understood that the fresh air needs to flow through the surfaces of the first wind blocking portion 510 and the second wind blocking portion 520 to enter the air inlet 211, so that the flow path of the fresh air is long, and the fresh air is easy to diffuse in all directions in the process of flowing through the wind blocking plate 500.

Through set up guiding gutter 530 on the surface at deep screen 500, sink deepest when can guide the new trend and collect towards guiding gutter 530 centre, effectively reduced the diffusion loss of new trend and indoor return air, improved the air output of wind channel subassembly 100.

Preferably, the flow guide grooves 530 are formed on the surfaces of the first wind blocking part 510 and the second wind blocking part 520.

Specifically, the surface shape of the heat exchanger 400 is matched with the surface shape of the wind deflector 500, which can increase the heat exchange area of the heat exchanger 400 and improve the heat exchange effect of the air duct assembly 100.

In some embodiments, a transition cavity 250 is formed between the air inlet cavity 210 and the first and second

air outlet cavities

220 and 230, and the flow cross-sectional area of the transition cavity 250 is smaller than that of the air inlet cavity 210, the first air outlet cavity 220 and the second air outlet cavity 230.

The cross section of the pipe hole perpendicular to the flow is called a through-flow cross section, and the size of the cross section is called a through-flow cross section; in the present application, the airflow flows from the air inlet cavity 210 into the first air outlet cavity 220 and the second air outlet cavity 230, so the cross-sectional area in the airflow direction of the airflow flowing from the air inlet cavity 210 into the first air outlet cavity 220 or the second air outlet cavity 230 is the through-flow cross-sectional area.

It should also be noted that the flow of gas from a duct with a larger cross-sectional flow area to a duct with a smaller cross-sectional flow area increases the velocity of the gas flow.

Therefore, by arranging the transition cavity 250, the air flow velocities in the first air outlet cavity 220 and the second air outlet cavity 230 can be increased, and the air outlet diffusion range of the air duct assembly 100 is further expanded; in addition, because the directions of the air flows thrown around the centrifugal wind wheel 300 are different, the transition cavity 250 can restrict and adjust the directions of the air flows entering the first air outlet cavity 220 and the second air outlet cavity 230, so that the flowing directions of most of the air flows are approximately consistent, the transition cavity has a certain rectification effect, the generation of vortex in the first air outlet cavity 220 and the second air outlet cavity 230 is effectively reduced, and further, the air volume loss of the air duct assembly 100 is reduced and the air noise is reduced.

In some embodiments, the inner sidewall of the housing 200 forming the transition chamber 250 is provided with an arc-shaped wind guide surface 251.

The air flow can smoothly flow through the arc-shaped air guide surface 251, so that the impact loss of the air flow when flowing through the transition cavity 250 is reduced, and the air output of the air duct assembly 100 is increased.

The present application further provides a window type air conditioner, which includes an outdoor module (not shown in the figures) and an indoor module (not shown in the figures), wherein the outdoor module is communicated with the indoor module, the indoor module includes a cover body (not shown in the figures) and the air duct assembly 100, and the cover body is covered on the air duct assembly 100. Since the window type air conditioner has the air duct assembly 100, all the same advantages are achieved, and the detailed description of the invention is omitted.
