The ducted air conditioner is generally installed in a suspended ceiling type. The existing air pipe machine only has the air outlet on the side wall, so that the air can only blow far, and the area (namely near) right below the air pipe machine can not blow the air. Therefore, in the refrigeration mode, the far part can be blown by cold air, and the near part cannot be blown, so that the temperature is uneven, and the comfort level of a user is reduced; in the heating mode, hot air rises upwards in a natural state, so that hot air is not available, and the comfort of a user is poor.

The air duct machine provided by the embodiment of the application can effectively solve the problems.

As shown in fig. 1 to 3, an embodiment of the present application provides a ducted air conditioner, including: the wind turbine comprises a casing 1, a first cross flow wind wheel 21, a second cross flow wind wheel 22, a first wind guide assembly 31 and a second wind guide assembly 32.

Wherein, the casing 1 is provided with an air return opening 13, a first air outlet 11 and a second air outlet 12. The first air outlet 11 is disposed on a side wall of the casing 1, the second air outlet 12 is disposed on a bottom wall of the casing 1, and a first air duct 14 and a second air duct 15 are disposed in the casing 1. The first air duct 14 is communicated with the air return opening 13 and the first air outlet 11, and the second air duct 15 is communicated with the air return opening 13 and the second air outlet 12.

The first wind wheel 21 is disposed in the first air duct 14 and configured to form an air flow from the air return opening 13 to the first air outlet 11. The second cross-flow wind wheel 22 is disposed in the second air duct 15, and configured to form an air flow flowing from the air return opening 13 to the second air outlet 12.

The second air guiding assembly 32 is disposed at the second air outlet 12 and configured to adjust an air outlet direction of the second air outlet 12.

The ducted air conditioner provided by the embodiment of the application comprises a casing 1, a first tubular wind wheel 21, a second tubular wind wheel 22, a first air guide assembly 31 and a second air guide assembly 32. The housing 1 is an appearance member and protects the internal structure. The first cross flow wind wheel 21 and the second cross flow wind wheel 22 can be driven by the motor to operate respectively, so that the surrounding air flows to form airflow. First air guide component 31 and second air guide component 32 can play the effect that changes the air-out direction, are convenient for adjust the air-out direction according to the user's demand, and then satisfy user's different demands, are favorable to improving user's use comfort.

Wherein, the casing 1 is provided with an air return opening 13, a first air outlet 11 and a second air outlet 12. The first air outlet 11 is disposed on a side wall of the casing 1, such as a front side wall, and can supply air to a remote location. The second air outlet 12 is disposed on the bottom wall of the casing 1, and can supply air downwards, that is, to the near place. Therefore, the double air outlets can effectively meet the air supply requirements of both near and far. In the cooling mode, as shown in fig. 2, the first air outlet 11 can blow cold air to a remote location, so as to lower the temperature of the remote location; second air outlet 12 can blow cold wind to near, makes near temperature reduction to be favorable to improving the homogeneity of far away near temperature, and then improve user's comfort level. The second air guiding assembly 32 can also change the air outlet direction of the second air outlet 12, so that cold air is prevented from blowing directly towards the user, and the use experience of the user is improved. In the heating mode, as shown in fig. 3, the first air outlet 11 can blow hot air to a far distance, and can blow the hot air to an obliquely lower side under the guidance of the first air guiding assembly 31, so that the hot air can be settled downwards, the use comfort of the user is improved, and the user can warm feet from the head; the second air outlet 12 can blow hot air directly downwards to the nearby area, so that vertical carpet type air supply is realized, the temperature of the nearby area is increased, and a foot warming effect is achieved.

Therefore, the ducted air conditioner that this application embodiment provided through setting up two air outlets and two air guide assemblies, can effectively solve the problem that current ducted air conditioner exists, improves user's use comfort.

The first air guiding assembly 31 can also function to open or close the first air outlet 11. The second wind guiding assembly 32 can also function to open or close the second wind outlet 12. Of course, a structure (e.g., a baffle) for opening or closing the first outlet 11 may be additionally provided, and a structure (e.g., a baffle) for opening or closing the second outlet 12 may be additionally provided. A return air grille can be arranged at the return air inlet 13.

In an exemplary embodiment, the second air deflection assembly 32 is configured as a non-wind-deflecting assembly.

The second air outlet 12 is disposed on the bottom wall of the casing 1, and is mainly used for blowing air downwards to the near place. Therefore, the second air guiding assembly 32 is set to be a non-wind-sensing air guiding assembly, so that air flow blown out from the second air outlet 12 can be scattered, a non-wind-sensing effect is achieved, cold wind blown out from the second air outlet 12 in a refrigeration mode can be prevented from blowing directly towards a user to cause discomfort of the user, and use experience of the user is further improved.

And first air outlet 11 can blow cold wind to the distant place horizontally under the guide of first air ducting component 31 under the cooling mode, and cold wind can sink under natural state, realizes flat blowing subsides formula cooling, therefore the cold wind that first air outlet 11 sent out can not directly blow to the user. Whereas no wind effect is generally required in heating mode. Therefore, the first air guiding assembly 31 can adopt a conventional air guiding assembly, such as one including at least one rotatable air guiding plate 321 (as shown in fig. 1), which is beneficial to reduce the product cost.

In an exemplary embodiment, the non-wind-induced-air-guiding assembly includes at least one air-guiding plate 321 rotatably connected to the casing 1, and the air-guiding plate 321 is provided with a wind breaking hole 3211, as shown in fig. 4.

This scheme is direct to set up a plurality of garrulous wind holes 3211 on aviation baffle 321 for the air current need blow off through garrulous wind hole 3211, and garrulous wind hole 3211 can break up the air current, makes the air-out disperse more, and is softer, thereby realizes no wind sense effect.

The air deflector 321 can rotate under the driving of the motor to adjust the air outlet direction. When no wind is needed to blow, the air guiding plate 321 can rotate to a position for closing the second outlet 12, and the airflow can only be blown out through the wind breaking holes 3211. When no wind sense is needed to blow, the air deflector 321 can rotate to the position for opening the second air outlet 12, and the opening angle can be adjusted according to the user requirement, and can also swing back and forth, so as to realize the wind sense mode.

The air breaking holes 3211 may be circular, square, triangular, or other shaped micropores, or may be elongated slit-shaped holes.

For example, the cross section of the wind deflector 321 may take the shape of a circular arc, a straight line, a zigzag line, or the like. The number of the air deflectors 321 is at least two, and the air deflectors may be distributed at equal intervals or at unequal intervals along the width direction of the second outlet 12.

In an exemplary embodiment, the non-wind inducing wind guide assembly comprises a cyclonic wind guide assembly, as shown in fig. 5 and 6. The whirl wind guide assembly includes: a swirl bracket 322 and swirl vanes.

Wherein, the rotational flow support 322 is connected with the casing 1. The swirling impeller 323 is mounted to the swirling bracket 322 and is configured to break up the airflow passing through the second air outlet 12.

In the scheme, the rotational flow air guide assembly can break up cold air by using the rotational flow impeller 323, so that a non-wind-sense effect can be realized.

The rotational flow air guide assembly comprises a rotational flow support 322 and a rotational flow impeller 323. The swirl bracket 322 is a mounting carrier for the swirl impeller 323. The swirl impeller 323 includes swirl blades for dispersing the wind out through the swirl blades.

In some embodiments, a mounting cavity may be disposed in the swirl bracket 322, one end of the mounting cavity facing the inside of the casing 1 may be opened, one end of the mounting cavity facing the outside of the casing 1 may be provided with a swirl exhaust hole, and the swirl impeller 323 may be disposed in the mounting cavity. Therefore, the air blown out from the second air duct 15 can enter the installation cavity, is scattered by the rotational flow impeller 323, is further scattered by the rotational flow air outlet hole and is blown out, so that a good non-wind effect is realized, and the user can be prevented from contacting with the rotational flow blades.

The number of the swirling flow impellers 323 is plural, and the plural swirling flow impellers 323 are arranged at intervals along the length direction of the second air outlet 12. The cyclone blades can be rotatably connected with the cyclone bracket 322, and wind is dispersed by the rotation of the blades; the swirl vanes may also be fixedly connected to the swirl support 322, and the swirl vanes themselves cut the airflow to break up the wind.

The swirl air guide assembly can further comprise a swirl driving device, and the swirl support 322 can change position under the driving of the swirl driving device, and can play a role in opening the second air outlet 12 or closing the second air outlet 12.

In an exemplary embodiment, the cyclonic air guiding assembly further comprises: a linkage 325 and a drive 324 as shown in fig. 6.

Wherein, the connecting rod 325 is movably connected with the bracket, and the rotational flow impeller 323 is also connected with the connecting rod 325. A drive device 324 (e.g., a motor) is coupled to the linkage 325 and configured to drive the linkage 325 relative to the support to oscillate the swirl vane 323 relative to the swirl support 322.

In this way, the swirl vane 323 can also play a role similar to a shutter, and can better adjust the air outlet direction of the second air outlet 12, thereby being beneficial to further improving the use comfort of users.

In an exemplary embodiment, the first air chute 14 includes a first volute. As shown in fig. 1, the first volute includes a first cover case 141 and a first volute tongue 142 that are oppositely disposed. The trajectory of first cover case 141 on a cross section perpendicular to the rotation axis of first through-flow wind rotor 21 includes first section 1411 and second section 1412 arranged in the direction of airflow.

The first section 1411 is set to be an involute taking the outer contour of the cross section of the first through wind wheel 21 as a base circle, and the second section 1412 is smoothly connected with the first section 1411.

The minimum gap width L1 between the first cover shell 141 and the first through wind wheel 21 is in the range of 3mm to 8mm, such as 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc. The minimum gap width L2 between the first volute tongue 142 and the first through wind wheel 21 is in a range of 3mm to 8mm, such as 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

The first cover case 141 covers the first wind turbine 21. The first volute tongue 142 is located relatively downward and is substantially located on the lower side of the first coherent wind rotor 21. Also, the area of the first cover case 141 is relatively large, and the area of the first volute tongue 142 is relatively small. Since the rotation axis of the first through-flow wind wheel 21 extends in the horizontal direction, the trajectory of the first cover casing 141 on a section perpendicular to the rotation axis of the first through-flow wind wheel 21, that is, the trajectory of the first cover casing 141 on a vertical section.

Tests prove that the first section 1411 and the second section 1412 are designed into the shapes, the minimum gap between the first cover shell 141 and the first through-flow wind wheel 21 is set in the range, and the minimum gap between the first volute tongue 142 and the first through-flow wind wheel 21 is set in the range, so that the air volume and the noise performance of the second air duct 15 are both considered.

The second segment 1412 may be configured as a straight line or an approximate straight line or an arc segment or a spline curve, etc.

In one example, the lower end of the second volute tongue 152 extends to the side wall of the casing 1, as shown in fig. 1. Therefore, the air blown out from the first air duct 14 cannot hit the bottom wall of the casing 1, which is beneficial to reducing air volume loss.

Of course, the lowest gap between the first cover shell 141 and the first wind turbine 21 is not limited to the above range, and the minimum gap between the first volute tongue 142 and the first wind turbine 21 is not limited to the above range, and may be adjusted as needed.

In an exemplary embodiment, the second air duct 15 includes a second volute. As shown in fig. 1, the second scroll casing includes a second cover case 151 and a second volute tongue 152 which are oppositely disposed. The trajectory of the second cover case 151 on a cross section perpendicular to the rotation axis of the second cross flow wind wheel 22 includes a third segment 1511 and a fourth segment 1512 arranged in the airflow direction.

The third section 1511 is set to be an involute taking the outer profile of the cross section of the second cross flow wind wheel 22 as a base circle, and the fourth section 1512 is smoothly connected with the third section 1511.

The minimum gap width L3 between the second cover case 151 and the second cross-flow wind wheel 22 is in the range of 3mm to 8mm, such as 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc., and the minimum gap width L4 between the second volute tongue 152 and the second cross-flow wind wheel 22 is in the range of 3mm to 8mm, such as 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, etc.

The second cover case 151 covers the second cross flow wind turbine 22. The second volute tongue 152 is located relatively downward and substantially on the lower side of the second impeller 22. Also, the area of the second cover case 151 is relatively large, and the area of the second volute tongue 152 is relatively small. Since the rotation axis of the second turbine rotor 22 extends in the horizontal direction, the trajectory of the second cover case 151 on a section perpendicular to the rotation axis of the second turbine rotor 22 is the trajectory of the second cover case 151 on a vertical section.

Tests prove that the third section 1511 and the fourth section 1512 are designed into the above shapes, the minimum gap between the second cover shell 151 and the second cross-flow wind wheel 22 is set within the above range, and the minimum gap between the second volute tongue 152 and the second cross-flow wind wheel 22 is set within the above range, which is beneficial to considering both the air volume and the noise performance of the second air duct 15.

The fourth segment 1512 may be a straight line or an approximate straight line or a circular arc, or a spline curve.

In one example, the lower end of the fourth segment 1512 extends to the bottom wall of the cabinet 1, as shown in FIG. 1. Therefore, the air blown out from the second air duct 15 cannot hit the side wall of the machine shell 1, and the reduction of air volume loss is facilitated.

Of course, the lowest gap between the second cover case 151 and the second turbine runner 22 is not limited to the above range, and the minimum gap between the second volute tongue 152 and the second turbine runner 22 is not limited to the above range, and may be adjusted as needed.

In one example, the trajectory of the first cover shell 141 on a cross-section perpendicular to the rotation axis of the first through-flow wind rotor 21 further includes a fifth section 1413 connected to the second section 1412, as shown in fig. 1. The fifth section 1413 extends obliquely upward along a direction close to the first air outlet 11, so as to increase the area of the first air outlet 11, and further increase the air output of the first air outlet 11.

In an exemplary embodiment, the air return opening 13 is disposed on a bottom wall of the housing 1, as shown in fig. 1, and the air return opening 13 is located between the first air outlet 11 and the second air outlet 12. A first heat exchanger 41 is arranged between the air return opening 13 and the air inlet of the first cross flow wind wheel 21, and a second heat exchanger 42 is arranged between the air return opening 13 and the air inlet of the second cross flow wind wheel 22.

Thus, the airflow can enter the casing 1 through the same air return opening 13, and then can enter the first air duct 14 and the second air duct 15 towards two sides respectively, or alternatively enter the first air duct 14 or the second air duct 15, so that the first cross flow wind wheel 21 and the second cross flow wind wheel 22 can operate together, or alternatively operate. The first heat exchanger 41 and the second heat exchanger 42 can ensure that the air blown out from the first air duct 14 and the second air duct 15 is the air after heat exchange treatment, so as to ensure the cooling effect or the heating effect.

Illustratively, as shown in fig. 1, the first air outlet 11 is disposed on a front side wall of the casing 1, the return air inlet 13 is disposed in a middle portion of a bottom wall of the casing 1, and the second air outlet 12 is disposed at a portion of the bottom wall of the casing 1 close to a rear side wall, that is, a rear portion of the bottom wall of the casing 1.

In an exemplary embodiment, as shown in fig. 1, the first heat exchanger 41 includes a first sub heat exchanger 411 and a second sub heat exchanger 412, the first sub heat exchanger 411 is located at a lower side of the first fan 21, and the second sub heat exchanger 412 is disposed obliquely with respect to the first sub heat exchanger 411 and forms a first rotation angle a with the first sub heat exchanger 411, the first rotation angle a is in a range between 90 ° and 150 °, such as 90 °, 100 °, 110 °, 120 °, 130 °, 140 °, 150 ° and the like.

As shown in fig. 1, the second heat exchanger 42 includes a third sub heat exchanger 421 and a fourth sub heat exchanger 422, the third sub heat exchanger 421 is located at the lower side of the second cross flow wind wheel 22, the fourth sub heat exchanger 422 is disposed obliquely with respect to the third sub heat exchanger 421 and forms a second rotation angle B with the third sub heat exchanger 421, and the second rotation angle B is in a range between 90 ° and 150 °, such as 90 °, 100 °, 110 °, 120 °, 130 °, 140 °, 150 °, and the like.

The first heat exchanger 41 adopts a multi-section structure, so that the space in the machine shell 1 is conveniently and reasonably utilized, and the contact area between air and the first heat exchanger 41 is increased, thereby improving the heat exchange effect. The first sub-heat exchanger 411 is the lowest section of the first heat exchanger 41, and a water pan is usually arranged below the first sub-heat exchanger. The included angle a between the first sub heat exchanger 411 and the second sub heat exchanger 412 is limited within the above range, so that the condensed water generated on the second sub heat exchanger 412 can flow onto the first sub heat exchanger 411 and drop into the water pan, and cannot directly drop into the room through the air return opening 13. The first sub heat exchanger 411 may be horizontally disposed.

Similarly, the second heat exchanger 42 adopts a multi-section structure, so that the space in the casing 1 is conveniently and reasonably utilized, and the contact area between the air and the second heat exchanger 42 is increased, thereby improving the heat exchange effect. The third sub heat exchanger 421 is the lowest section of the second heat exchanger 42, and a water receiving tray is usually arranged below the third sub heat exchanger. The included angle B between the fourth sub heat exchanger 422 and the third sub heat exchanger 421 is limited in the above range, so that the condensed water generated on the fourth sub heat exchanger 422 can flow onto the third sub heat exchanger 421 and drip into the water pan, and cannot directly drip into the room through the air return opening 13. The third sub heat exchanger 421 may be horizontally disposed.

Of course, the angular ranges of the first and second rotation angles are not limited to the above ranges, and may be adjusted as necessary.

In an exemplary embodiment, as shown in fig. 1, a first crossflow wind wheel 21 is arranged side by side with a second crossflow wind wheel 22. The first heat exchanger 41 includes a fifth sub heat exchanger 413, and the second heat exchanger 42 includes a sixth sub heat exchanger 423. The fifth sub heat exchanger 413 and the sixth sub heat exchanger 423 are located between the first cross flow wind wheel 21 and the second cross flow wind wheel 22. The fifth sub heat exchanger 413 may be connected to an end of the second sub heat exchanger 412, and an angle of the fifth sub heat exchanger 413 with the vertical direction may be smaller than an angle of the second sub heat exchanger 412 with the vertical direction. The sixth sub heat exchanger 423 may be connected to an end of the fourth sub heat exchanger 422, and an angle of the sixth sub heat exchanger 423 with respect to the vertical direction may be smaller than an angle of the fourth sub heat exchanger 422 with respect to the vertical direction.

As shown in fig. 1, the fifth sub heat exchanger 413 extends obliquely in a direction approaching the second cross flow wind wheel 22 and the sixth sub heat exchanger 423 extends obliquely in a direction approaching the first cross flow wind wheel 21 in a direction from the bottom wall to the top wall of the casing 1. The inclination angle of the sixth sub heat exchanger 423 with respect to the fifth sub heat exchanger 413 is in the range of 15 ° to 85 °.

With such an arrangement, the contact area between the airflow and the first heat exchanger 41 is increased, the contact area between the airflow and the second heat exchanger 42 is increased, and the heat exchange effect of the first heat exchanger 41 and the second heat exchanger 42 is improved.

The inclination angle of the sixth sub heat exchanger 423 relative to the fifth sub heat exchanger 413 (i.e. the included angle C between the sixth sub heat exchanger 423 and the fifth sub heat exchanger 413) is limited to the range of 15 ° to 85 °, such as 15 °, 30 °, 45 °, 60 °, 75 °, 85 °, and the like, so that the case 1 can be prevented from being oversized due to the oversized distance between the first cross flow wind wheel 21 and the second cross flow wind wheel 22, and the heat exchange effect and the miniaturization of the machine are both facilitated.

Of course, the inclination angle of the sixth sub heat exchanger 423 with respect to the fifth sub heat exchanger 413 is not limited to the above range, and may be adjusted as needed.

In an exemplary embodiment, as shown in fig. 1, the top end of the fifth sub heat exchanger 413 contacts the top end of the sixth sub heat exchanger 423.

Therefore, the distance between the first tubular wind wheel 21 and the second tubular wind wheel 22 is further reduced, the size of the casing 1 is further reduced, and airflow loss caused by airflow impacting the top wall of the casing 1 can be reduced.

In an exemplary embodiment, the diameter of the first through-flow wind rotor 21 is in the range of 80mm to 125mm, such as 80mm, 90mm, 100mm, 110mm, 120mm, 125mm, etc. The diameter of the second cross flow wind wheel 22 is in the range of 80mm to 125mm, such as 80mm, 90mm, 100mm, 110mm, 120mm, 125mm, etc.

The verification proves that the air quantity and the noise performance of the air pipe machine can be considered at the same time.

The first cross flow wind wheel 21 and the second cross flow wind wheel 22 can adopt a straight tooth or helical tooth mode. The first cross flow wind wheel 21 and the second cross flow wind wheel 22 can be suction type cross flow wind wheels or blowing type cross flow wind wheels.

Of course, the diameter of the first tubular vane 21 and the diameter of the second tubular vane 22 are not limited to the above ranges, and may be adjusted as needed.

To sum up, the tuber pipe machine that this application embodiment provided, it is wide to refrigerate and heat the air supply scope, and indoor impression travelling comfort is good, can solve under the refrigeration mode problem that near cold wind can not blow and heat the mode problem that hot-blast can not come down, and the air supply can realize no wind effect, avoids cold wind to directly blow.
