Referring to fig. 1 to 5, the cabinet air-conditioning indoor unit 1 of the present invention includes a casing 40, a through channel 41 penetrating the casing 40 from front to back, and a first heat exchange air duct 42 and a second heat exchange air duct 43 respectively located at two lateral sides of the through channel 41 and independent from each other are formed inside the casing 40, the first heat exchange air duct 42 and the second heat exchange air duct 43 both have heat exchange air flow outlets, and a heat exchanger and a fan are respectively disposed inside the first heat exchange air duct 42 and the second heat exchange air duct 43, so that the heat exchange air flows in the first heat exchange air duct 42 and the second heat exchange air duct 43 are forced to be sent out through their own heat exchange air flow outlets by the fan. Specifically, two separate volute tongue assemblies 46 may be disposed inside the casing 40 to define, together with the casing 40, the first heat exchange air duct 42 and the second heat exchange air duct 43 that are independent of each other. The air paths of the first heat exchange air duct 42 and the second heat exchange air duct 43 are independent from each other, the first heat exchange air duct 42 has a first heat exchange airflow outlet 421, a first heat exchanger 51 and a first fan 61 are arranged in the first heat exchange air duct 42, the first heat exchanger 51 is used for exchanging heat with the airflow in the first heat exchange air duct 42 to generate heat exchange airflow, and the first fan 61 is used for promoting the heat exchange airflow to flow to the first heat exchange airflow outlet 421 and flow out through the first heat exchange airflow outlet 421. Similarly, the second heat exchange air duct 43 has a second heat exchange air outlet 431, and the second heat exchanger 52 and the second fan 62 are disposed therein. The second heat exchanger 52 is configured to exchange heat with the air flow in the second heat exchange air duct 43 to generate a heat exchange air flow, and the second fan 62 is configured to promote the heat exchange air flow to the second heat exchange air flow outlet 431 and flow out through the second heat exchange air flow outlet 431.
In particular, the cabinet air conditioner indoor unit 1 further comprises a jet air duct 10 and a jet fan 20. The jet air duct 10, the first heat exchange air duct 42 and the second heat exchange air duct 43 are independently and fixedly disposed inside the through channel 41. That is, the jet air duct 10 is fixed inside the through passage 41 and is independent from the first heat exchange air duct 42 and the second heat exchange air duct 43, and the air ducts of the three air ducts are independent from each other and do not affect each other. The jet fan 20 is configured to controllably drive air outside the cabinet air conditioner indoor unit 1 to flow toward the jet air duct 10 and to be discharged through the jet air duct 10, so that natural air that has not been subjected to heat exchange and flows out through the jet air duct 10 is mixed with heat exchange air flows discharged through the first heat exchange air duct 42 and the second heat exchange air duct 43.
That is, the present invention actively injects the external air into the jet flow duct 10 through the jet flow fan 20, and the natural air which flows out from the jet flow duct 10 and is not subjected to heat exchange is mixed with the heat exchange air flow flowing out from the heat exchange air flow outlets of the two heat exchange air ducts to form a softer mixed air, so as to avoid the air outlet of the cabinet air conditioner indoor unit 1 from being too cold or too hot, and improve the comfort experience of the cabinet air conditioner indoor unit. Compared with the mode of utilizing negative pressure passive drainage in the prior art, the invention greatly improves the jet flow quantity and increases the air supply distance by arranging the jet fan 20 to actively jet, improves the soft air supply effect of the cabinet air conditioner indoor unit 1, increases the whole air supply quantity and enlarges the air supply range. In addition, the air volume entering the jet air duct 10 is closely related to the rotating speed of the jet fan 20, is not influenced by other external factors, and is relatively stable in jet air volume.
In some embodiments, the heat exchange airflow outlets of the first heat exchange air duct 42 and the second heat exchange air duct 43 face the front side of the casing 40, and the front side of the jet air duct 10 is provided with the jet air outlet 12. That is, the three air ducts all blow air toward the front side of the cabinet 40 so that the heat exchange air flows flowing out of the two heat exchange air ducts are mixed with the natural air flowing out of the jet air duct 10 without heat exchange at the front side or front portion of the cabinet 40. And, set up efflux wind channel 10 in being in the through channel 41 between two heat transfer wind channels, can make efflux wind channel 10 be in between two heat transfer wind channels to make the natural air that efflux wind channel 10 sent out be in between two strands of heat transfer air flows, and then make the mixing between natural air and the heat transfer air flow more even. It should be noted that the front side of the casing 40 referred to in the present invention may include a front side of the casing 40, and may also include an inclined front side of the casing 40, as long as the heat exchange airflow outlet is oriented to have a forward direction component so as to be capable of blowing air toward the front side of the casing 40.
Further, two lateral duct walls 10f of the jet duct 10 are respectively disposed at intervals from two lateral side walls 41a of the through channel 41 to respectively form one air inducing channel 44 at two lateral outer sides of the jet duct 10. When the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 are operated and/or when the jet fan 20 is operated, a certain negative pressure is generated in the front of the induced air passage 44. Under the action of the negative pressure, the air in the space where the cabinet air conditioner indoor unit 1 is located flows into the induced air channel 44, and is discharged through the front opening of the induced air channel 44, and is mixed with the natural air which flows out through the jet air duct 10 and is not subjected to heat exchange and the heat exchange air flow which is discharged through the first heat exchange air duct 42 and the second heat exchange air duct 43. Therefore, the amount of natural air which is introduced into the cabinet air conditioner indoor unit 1 and is not subjected to heat exchange is increased, and the whole air supply amount is increased.
In some embodiments, the jet air duct 10 is fixedly arranged within the rear section 411 of the through channel 41 to convey natural air through the jet outlet 12 towards the front section 412 of the through channel 41. It will be understood by those skilled in the art that the term natural air as used herein means air that has not been heat exchanged.
Further, the heat exchange air flow outlets of the first heat exchange air duct 42 and the second heat exchange air duct 43, and each air inducing channel 44 are communicated with the front section 412 of the through channel 41. That is, the heat-exchange air flows flowing out of the two heat-exchange air ducts, the natural air flowing out of the jet air duct 10, and the natural air flowing out of the two air-guide ducts 44 are collected and mixed to some extent in the front section 412 of the through duct 41, and the whole is sent forward from the front section of the through duct 41, and the air-supply port 453 of the cabinet air-conditioning indoor unit 1 is formed at the front end of the through duct 41. The mixing effect is better by pre-mixing the air flows of the air passages and then sending the air flows out.
In some alternative embodiments, the two lateral duct walls 10f of the jet duct 10 can also abut against the two lateral side walls 41a of the through duct 41, respectively, in which case the jet duct 10 occupies almost the entire space behind the through duct 41, so that the natural air introduced by the cabinet air conditioner indoor unit 1 is delivered through the jet duct 10.
In some embodiments, the casing 40 further defines a first air inlet 451 and a second air inlet 452, and the first heat exchange air duct 42 and the second heat exchange air duct 43 are respectively communicated with the first air inlet 451 and the second air inlet 452, so that the air outside the cabinet air conditioner indoor unit 1 is forced to flow into the first heat exchange air duct 42 through the first air inlet 451 by the first fan 61, and the air outside the cabinet air conditioner indoor unit 1 flows into the second heat exchange air duct 43 through the second air inlet 452 by the second fan 62.
Further, the through channel 41 may be formed in the middle of the casing 40, and the first air inlet 451 and the second air inlet 452 may be respectively located at two lateral sides of the casing 40 to prevent the air inlets of the first heat exchange air duct 42 and the second heat exchange air duct 43 from interfering. The heat exchangers in the first heat exchange air duct 42 and the second heat exchange air duct 43 and the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 are symmetrically arranged with respect to the vertical bisecting plane m of the casing 40 in the transverse direction, that is, the first heat exchanger 51 and the second heat exchanger 52 are symmetrically arranged in the left-right direction, and the first fan 61 and the second fan 62 are symmetrically arranged in the left-right direction.
In some embodiments, the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 are cross-flow fans with rotating shafts extending in the vertical direction. That is, the first fan 61 and the second fan 62 are both cross-flow fans extending vertically, and accordingly, the first air inlet 451, the second air inlet 452, the first heat exchange air flow outlet 421, the second heat exchange air flow outlet 431, the jet air outlet 12, and the air supply outlet 453 are all elongated air outlets extending vertically. The jet air duct 10 is an elongated air duct extending vertically. Therefore, the air outlet height of the cabinet air conditioner indoor unit 1 in the vertical direction can be increased, and the air supply range is expanded. The first and second heat exchangers 51 and 52 are V-shaped or arc-shaped heat exchangers disposed laterally outside the first and second fans 61 and 62, respectively.
In some embodiments, the rear section 411 of the through channel 41 tapers from back to front, and the shape of the jet air duct 10 matches with the shape of the rear section 411 of the through channel, on one hand, the structural layout between the jet air duct 10 and the through channel 41 can be made more compact to reduce the volume of the cabinet air conditioner indoor unit 1, and on the other hand, the formation of the flow guide cavity 11 tapering from back to front in the jet air duct 10 is also facilitated, so that natural air rapidly flows out from the jet air outlet 12.
Further, the cross section of the jet flow duct 10 has a trapezoidal shape that tapers from rear to front, and a rear-facing surface 10e of the jet flow duct 10 is flush with the rear-facing surface 40a of the cabinet 40. Therefore, the appearance integrity and the appearance of the cabinet air-conditioner indoor unit 1 can be improved. Further, the cross section of the jet flow duct 10 may be an isosceles trapezoid.
In some embodiments, the jet fan 20 is a centrifugal fan disposed below the jet air duct 10 and communicated with the jet air duct 10, so as to controllably drive the air outside the cabinet air conditioner indoor unit 1 to horizontally flow into the centrifugal fan and flow into the jet air duct 10 from bottom to top.
The jet fan 20 is selected as a centrifugal fan and is positioned below the jet air duct 10, so that the size of an assembly formed by the jet fan 20 and the jet air duct 10 in the transverse direction is reduced as much as possible, and the height of the assembly in the vertical direction is increased, therefore, the advantage of the cabinet air conditioner indoor unit 1 in the height direction can be fully utilized, the layout among the structures such as the jet air duct 10, the jet fan 20 and a shell 40 of the cabinet air conditioner indoor unit is more compact, the adoption of a through-flow type jet fan is avoided, and the problem that the size of the jet air duct in the horizontal direction is overlarge and further the volume of the cabinet air conditioner indoor unit is overlarge due to the overlarge jet air duct in the horizontal direction and the occupation of indoor space due to the fact that the through-flow type jet fan is arranged in the jet air duct is solved.
The air supply port 453 of the cabinet air-conditioning indoor unit is usually a vertically extending strip-shaped air supply port, and for this reason, the heat exchange airflow outlets of the first heat exchange air duct 42 and the second heat exchange air duct 43 and the jet air outlet 12 formed in the front side of the jet air duct 10 are strip-shaped air ports extending vertically, so as to increase the air outlet height of the cabinet air-conditioning indoor unit 1 in the vertical direction and expand the air supply range thereof.
However, the jet fan 20 is located below the jet air duct 10, and the airflow flows into the air outlet duct 20 from the bottom to the top, and is perpendicular to the air outlet direction of the jet air outlet 12, so how to ensure that the jet air outlet 12 sends the airflow with a high flow rate and how to achieve uniform air outlet of the jet air outlet 12 in the vertical direction are design difficulties and design points of further embodiments of the present application.
Fig. 6 is a schematic structural sectional view taken along a vertical sectional plane extending in the front-rear direction of the jet flow duct according to one embodiment of the present invention, fig. 7 is a schematic enlarged view of a portion C in fig. 6, and fig. 8 is a schematic sectional view taken along a horizontal sectional plane of the jet flow duct according to one embodiment of the present invention. Referring to fig. 6 to 8, in some embodiments, a guide cavity 11 extending vertically is defined in the jet air duct 10, and the air flow entering the jet air duct 10 is guided by the guide cavity 11 and then flows out from the jet air outlet 12 of the jet air duct 10. Two arc-shaped guide plates 13 extending vertically are symmetrically arranged inside the jet air duct 10, and the two arc-shaped guide plates 13 are convexly bent from back to front towards the direction close to each other, so that the front part of the guide cavity 11, which is close to the strip-shaped jet air outlet 12, forms a gradually-reduced arc-shaped closing part 111. That is, the arc-shaped mouth portion 111 is tapered from back to front and is substantially funnel-shaped from back to front. The tapered arc-shaped closing part formed by the guide plate in the shape can reduce the airflow flowing resistance as much as possible and improve the airflow velocity flowing to the jet flow air outlet 12, thereby improving the air outlet speed of the jet flow device 1 and prolonging the air supply distance thereof.
In some embodiments, the cross section of the jet air duct 10 is a trapezoid, an upper bottom of the trapezoid is located on the front side of the strip-shaped jet air outlet 12, and a lower bottom of the trapezoid is located on the rear side away from the strip-shaped jet air outlet 12. The rear ends of the two arc-shaped guide plates 13 are respectively bent and extended forwards by the two side plates of the jet flow air duct 10 corresponding to the two trapezoidal waists. Specifically, the jet duct 10 has a front side plate 10a, a rear side plate 10b, and two lateral side plates 10 c. The outer side surface of the rear side plate 10b forms a rear facing surface 10e of the jet duct 10, and the outer side surface of the lateral side plate 10c forms a lateral duct wall 10f of the jet duct 10. The jet air outlet 12 is arranged on the front side plate 10a, the cross section of the front side plate 10a is a trapezoidal upper bottom, the cross section of the rear side plate 10b is a trapezoidal lower bottom, and the cross sections of the two transverse side plates 10c are trapezoidal two waists. The two arc-shaped guide plates 13 are bent and extended forwards from the inner surfaces of the two transverse side plates 10c respectively. That is, the rear ends of the two arc-shaped baffles 13 do not extend to the rearmost side of the jet duct 10. The baffle chamber 11 thus formed comprises two parts, namely an arc-shaped mouth portion 111 at the front and a trapezoid-shaped cavity 112 at the rear, and the boundary between the trapezoid-shaped cavity 112 and the arc-shaped mouth portion 111 is shown by a dotted line in fig. 8.
The trapezoidal cavity 112 has a shape that is gradually reduced from back to front so that the airflow flows toward the arc-shaped closing-in portion 111 at an accelerated speed, and the rear side of the trapezoidal cavity 112 has a larger area so that the airflow entering the jet flow duct 10 flows from bottom to top through the rear side of the trapezoidal cavity 112, thereby reducing the flow resistance of the airflow and facilitating the formation of more uniform air supply at the jet flow air outlet 12.
In some embodiments, the arc-shaped mouth part 111 extends forward to the strip-shaped jet air outlet 12, and the size of the foremost end of the arc-shaped mouth part 111 in the transverse direction is identical to the size of the jet air outlet 12 in the transverse direction. That is, the foremost end of the arc-shaped mouth 111 is in seamless butt joint with the jet flow outlet 12, so that the turbulence phenomenon near the jet flow outlet 12 can be avoided.
In some embodiments, the flow guide cavity 11 is tapered in cross-section in a direction from back to front. Specifically, the cross section of the diversion cavity 11 may be in a regular tapered shape in the front-rear direction, or may be in an irregular tapered shape. For example, the diversion cavity 11 shown in fig. 8 has a trapezoidal cavity 112 and an arc-shaped closing part 111 arranged from back to front, and both the trapezoidal cavity 112 and the arc-shaped closing part 111 are tapered from back to front, so that the diversion cavity 11 is formed in a tapered shape that is irregular from back to front.
Further, the width W of the rearmost end of the guide chamber 11 in the lateral direction4Is the width W of the jet flow air outlet 12 in the transverse direction65 to 10 times of the total weight of the composition. Because the diversion cavity 11 tapers from back to front, the arc-shaped closing-in part 111 is in seamless butt joint with the jet flow air outlet 12, the width of the rearmost end of the diversion cavity 11 is the maximum width of the diversion cavity, and the width of the jet flow air outlet 12 is the minimum width of the diversion cavity 11. That is, the maximum width of the diversion cavity 11 is 5 to 10 times of the minimum width thereof. For example, the maximum width of the diversion cavity 11 may be 5 times, 6 times, 7 times, 8 times, 9 times, or 10 times its minimum width. From this, can ensure on the one hand that water conservancy diversion chamber 11 rear portion has can make the most air current that gets into in efflux wind channel 10 upwards flow the area, on the other hand still makes efflux air outlet 12's width small enough, makes its whole slit form efflux air outlet 12 that is vertical extension so that the air current obtains big enough acceleration when flowing forward by the back to obtain great air-out speed and air supply distance. More importantly, the jet flow air outlet 12 can uniformly output air in the vertical direction. The above-mentioned proportional design of the maximum width and the minimum width of the diversion cavity 11 is a result obtained by balancing various technical problems, and a better technical effect is achieved in all the aspects. On the contrary, if the width of the rearmost end of the diversion cavity 11 is too large compared with the width of the jet flow outlet 12, the area of the rear part of the diversion cavity 11 is too large, the distance between the airflow and the jet flow outlet 12 is far when the airflow flows through the rear part of the diversion cavity 11, and most of the airflow directly flows upwards through the rear part of the diversion cavity 11 at the momentAnd the air flow flowing to the jet flow air outlet 12 is very small, so that the air output at the top of the jet flow air outlet 12 is relatively large, the air output at the bottom and the middle of the jet flow air outlet 12 is very small, and the air output of the jet flow air outlet 12 is very unbalanced. If the width of water conservancy diversion chamber 11 rearmost end is less with the width multiple of efflux air outlet 12, the width difference between the two is less, and the acceleration effect that the air current obtained when flowing forward by the back is not obvious, and the air-out speed and the air supply distance of efflux air outlet 12 are all smaller.
In some embodiments, the flow guide cavity 11 is tapered in cross-section in a direction from back to front. Width W of rearmost end of flow guide cavity 11 in lateral direction4And the depth H of the diversion cavity 11 in the front and back directions4The ratio of the two is any ratio in the range of 2: 11-2: 9. For example, width W4And depth H4The ratio between may be 2:11, 2:10 or 2: 9. Therefore, a reasonable proportional relation is kept between the air flow allowed to pass through the rear part of the diversion cavity 11 and the air flow capable of obtaining better acceleration in the diversion cavity 11 from back to front, and the width W is avoided4And depth H4Too small a ratio therebetween results in insufficient acceleration or width W of the air flow to the jet outlet 124And depth H4The too large ratio between them causes the problem that the air flow to the bottom of the jet flow air outlet 12 is large and the air flow to the bottom of the jet flow air outlet 12 is small.
In some embodiments, the length H of the curved baffle 13 in the fore-aft direction5And the depth H of the diversion cavity 11 in the front and back directions4The ratio between the two is any ratio in the range of 4: 11-7: 11. It can be understood that the length H of the arc-shaped baffle 13 in the front-rear direction5The front end and the rear end of the arc-shaped guide plate 13 are vertically spaced in the front-rear direction. For example, length H5And depth H4The ratio therebetween may be 4:11, 5:11, 6:11, or 7: 11. Therefore, on one hand, the rear part of the diversion cavity 11 can be ensured to have an area which can enable most of the airflow entering the jet flow air duct 10 to flow upwards, and on the other hand, the arc-shaped closing part 111 can be ensured to have a reasonable length, so that the part of the airflow flowing from bottom to top can be accelerated better, and the airflow can flow upwardsAnd obtaining a larger air outlet speed. On the contrary, if the length H is long5And depth H4If the ratio is too small, the acceleration of the air flow by the arc-shaped closing-in portion 111 is not obvious, and the air outlet speed of the jet air outlet 12 is low. If the length H is5And depth H4If the ratio between the air flow and the air flow is too large, most of the air flow in the diversion cavity 11 can be sent out from the bottom of the jet air outlet 12 at an accelerated speed under the action of the arc-shaped closing-in part 111, so that the phenomenon of uneven air supply caused by large bottom air volume and small top air volume of the jet air outlet 12 is caused.
In some embodiments, a plurality of flow deflectors 14 extending in the front-back direction are disposed inside the flow guiding cavity 11 and located inside the jet flow outlet 12, and the plurality of flow deflectors 14 are arranged at intervals in the vertical direction and are used for guiding the airflow in the flow guiding cavity 11 to flow toward the jet flow outlet 12.
Further, the length W of the guide vane 14 in the front-rear direction1The length H of the arc-shaped guide plate 13 in the front-back direction is less than or equal to5So that the guide vane 14 is within the arcuate mouth 111. That is to say, this application is equipped with a plurality of baffles 14 along vertical interval arrangement in arc closing-in portion 111 to make the air-out of efflux air outlet 12 on vertical direction more even through the cooperation of arc closing-in portion 111 and baffles 14. The baffle 14 is located in the arc-shaped closing-in portion 111, which can avoid the guiding effect of the front-back direction on the air flow flowing in the rear space of the baffle cavity 11, so as to facilitate the air flow entering the jet air duct 10 to flow from bottom to top, and facilitate the jet air outlet 12 to realize the uniform air outlet in the vertical direction.
In some embodiments, a plurality of flow deflectors 14 extending in the front-back direction are disposed inside the flow guiding cavity 11 and located inside the jet flow outlet 12, and the plurality of flow deflectors 14 are arranged at intervals in the vertical direction and are used for guiding the airflow in the flow guiding cavity 11 to flow toward the jet flow outlet 12. Further, the strip-shaped jet outlet 12 is located at the front side of the jet air duct 10, and the baffle 14 may include an arc-shaped section 141 extending from the rear to the front in a curved manner from bottom to top, and a straight section 142 extending from the end of the arc-shaped section 141 to the strip-shaped jet outlet 12 in a forward manner. Therefore, a preset amount of airflow in the airflow flowing from bottom to top can be retained inside the arc-shaped section 141, the airflow is guided to the straight section 142 on the premise of reducing the flow resistance of the part of airflow after encountering the arc-shaped section 141 as much as possible, and the preset amount of airflow is guided to the jet flow outlet 12 through the straight section 142, so that the air outlet uniformity of the jet flow outlet 12 in the vertical direction is further improved through the matching of the plurality of guide vanes 14.
Furthermore, the front part of the flow deflector 14 adjacent to the jet flow air outlet 12 is particularly designed with a straight section 142, and the air flow can be guided to horizontally pass through the jet flow air outlet 12 through the straight section 142, so that the direction of the air flow sent out by the jet flow device 1 is consistent with the direction of the air flow sent out by the heat exchange air flow outlet of the cabinet air-conditioning indoor unit, and the overall air supply speed and the overall air supply distance of the cabinet air-conditioning indoor unit are higher and longer on the premise of ensuring the better mixing effect of the two air flows.
In some embodiments, the length W of the arcuate section 141 in the fore-aft direction3A length W of the straight section 142 in the front-rear direction or longer2. Thus, on the one hand, the arc-shaped section 141 can be made to have a relatively long length in the front-rear direction to increase the length of the guide path of the air flow by the arc-shaped section 141 and reduce the curvature of the arc-shaped section 141, thereby reducing the flow resistance of the air flow after encountering the arc-shaped section 141 as much as possible. On the other hand, on the basis of ensuring the normal flow guiding function of the straight section 142, the length of the straight section 142 in the front-back direction is shorter, so that the length of the whole flow deflector 14 in the front-back direction is reduced, the size of the jet device 1 in the front-back direction is reduced, and the jet device is more suitable for a cabinet air conditioner indoor unit with a compact structure and a high volume requirement.
In some embodiments, the straight section 142 of each guide vane 14 has an equal length in the fore-aft direction, and the curved section 141 of each guide vane 14 has an equal length in the fore-aft direction. That is, the size of each guide vane 14 is the same, so as to facilitate mold opening and save cost. The applicant verifies through deep analysis and a large amount of simulation, experiments and the like that: as long as the sizes of the diversion cavity 11, the arc-shaped diversion plate 13 and/or the diversion sheet 14 are designed according to the scheme in the above embodiment, and the jet fan 20 continuously supplies air towards the jet air duct 10, even if the sizes of each diversion sheet 14 are the same, uniform air outlet of the jet air outlet 12 in the vertical direction can be realized.
In other embodiments, the straight section 142 of each guide vane 14 has the same length in the front-rear direction, and the arc-shaped sections 141 of the plurality of guide vanes 14 arranged in sequence from bottom to top have sequentially increasing lengths in the front-rear direction. Therefore, the problem that the airflow remaining inside the guide vane 14 is too much due to the fact that the guide vane 14 located at the bottom extends out too long backwards, so that the airflow at the top inside the guide chamber 11 is less can be avoided, and meanwhile, the problem that the airflow guided by the upper guide vane 14 is less due to the fact that the arc-shaped sections 141 of the guide vanes 14 are long and possible can be avoided, so that the uniform air outlet of the jet air outlet 12 in the vertical direction is ensured.
Further, the rear end portions of the plurality of guide vanes 14 are in an inclined straight line. That is to say, the arc-shaped sections 141 of the plurality of guide vanes 14 arranged from bottom to top in sequence are extended in sequence at equal intervals, so as to further ensure the uniform air outlet of the jet air outlet 12 in the vertical direction.
In some embodiments, the bottom of the jet stack 10 is in fluid communication with the top of the jet fan 20 via a volute stack 30. Specifically, the volute air duct 30 extends vertically. The air inlet of the jet air duct 10 is arranged at the bottom of the jet air duct, the airflow outlet of the jet fan 20 is arranged at the top of the jet air duct, and a volute air duct 30 is hermetically connected between the air inlet of the jet air duct 10 and the airflow outlet of the jet fan 20 so as to guide the airflow sent out by the jet fan 20 to the jet air duct 10. In general, the air supply port 453 of the cabinet air conditioner indoor unit and the two heat exchange airflow outlets are not adjacent to the ground but have a certain height in order to obtain a preferable air supply range. In order to avoid the jet air outlet 12 of the jet air duct 10 from being too low, the volute air duct 30 is arranged between the bottom of the jet air duct 10 and the top of the jet fan 20, so that the jet air duct 10 is better matched with the casing 40, the through channel 41 and the structures of the two heat exchange air ducts of the cabinet air conditioner indoor unit 1.
Further, the height of the volute air duct 30 in the vertical direction is set so that the height of the jet air outlet 12 of the jet air duct 10 is consistent with the height of the heat exchange air flow outlets of the first heat exchange air duct and the second heat exchange air duct, so that the air flow sent out from the jet air outlet 12 is better mixed with the heat exchange air flow flowing out from the heat exchange air flow outlets.
In some embodiments, the through channel 41 penetrates the upper portion of the cabinet 40 in the front-rear direction, that is, the through channel 41 is formed only in the middle of the upper portion of the cabinet 40. The jet fan 20 and the volute air duct 30 are both fixedly arranged at the lower part in the casing 40, so as to prevent the jet fan 20 and the volute air duct 30 from being exposed outside to influence the appearance of the cabinet air conditioner indoor unit 1.
Further, the airflow inlet of the jet fan 20 faces the rear side of the casing 40, and the rear wall of the casing 40 is provided with a jet air inlet grille 47 opposite to the airflow inlet of the jet fan 20, so that air outside the cabinet air conditioner indoor unit 1 enters the jet fan 20 of the casing 40 through the jet air inlet grille 47.
