Referring to fig. 1 to 6, 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 and the first and second heat exchange air ducts 42 and 43 are provided inside the through passage 41 independently of each other. That is, the jet air duct 10 is disposed 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. And, at least one induced air channel 44 is defined between the air duct wall of the jet air duct 10 and the side wall of the through channel 41, and when the fans in the first heat exchange air duct 42 and the second heat exchange air duct 43 operate and/or when the jet fan 20 operates, a certain negative pressure is generated at the front of the induced air channel 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.
Further, the jet duct 10 is configured to be controllably or operatively movable within the through channel 41 to open and close the at least one induced air channel 44 and/or to adjust an area of flow of the at least one induced air channel 44. Fig. 5 shows a state in which the air inducing passage 44 is opened, and fig. 6 shows a state in which the air inducing passage 44 is closed. That is, the distance between the air duct wall of the jet air duct 10 and the side wall of the through channel 41 can be adjusted by moving the jet air duct 10, so as to open and close the induced air channel 44 or adjust the size of the induced air channel 44, thereby omitting a mechanism for specially controlling the opening and closing of the induced air channel 44 or adjusting the size of the induced air channel 44, and simplifying the structure of the cabinet type air conditioner indoor unit 1.
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 flow out through the jet air duct 10, so that natural air flowing out through the jet air duct 10 without heat exchange is mixed with heat exchange air flowing out through the first heat exchange air duct 42 and the second heat exchange air duct 43.
When the non-heat-exchanged natural air needs to be introduced, the movable jet flow air duct 20 opens the air inducing channel 44, the jet flow fan 20 is started, the natural air is actively injected into the jet flow air duct 10 through the jet flow fan 20, and meanwhile, part of the non-heat-exchanged external air enters the air inducing channel 44 under the negative pressure effect. The natural air which flows out of the jet air duct 10 and the induced air channel 44 and does not undergo heat exchange is mixed with the heat exchange air flow flowing out of the heat exchange air flow outlets of the two heat exchange air ducts to form soft mixed air, so that the cold or overheat of the air outlet of the cabinet air conditioner indoor unit 1 is avoided, and the comfort experience of the cabinet air conditioner indoor unit is improved. Compared with the mode of only utilizing negative pressure passive drainage in the prior art, the active jet flow of the jet flow fan 20 is added on the basis of passive drainage, the jet flow volume and the air induction volume are greatly improved, the air supply distance is increased, the soft air supply effect of the cabinet air conditioner indoor unit 1 is improved, the whole air supply volume is increased, and the air supply range is enlarged. Meanwhile, the total amount of the introduced natural air can be accurately controlled by controlling the position of the jet flow air duct 10 to adjust the flow area of the induced air channel 44 and combining the rotating speed of the jet flow fan 20. When the amount of natural air to be introduced is not large, the movable jet air duct 10 closes the air inducing channel 44 and only the jet fan 20 is started. When rapid cooling or heating is required, the movable jet air duct 10 closes the induced air channel 44, and the jet fan 20 is not started, so that almost all the heat exchange air flow is sent out to meet the requirements of rapid cooling or rapid heating.
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 transverse air duct walls 10f of the jet air duct 10 are respectively arranged at intervals with two transverse side walls 41a of the through channel 41, so as to respectively form an air inducing channel 44 at two transverse outer sides of the jet air duct 10, so as to simultaneously introduce natural air from two transverse sides, and thus the mixing of the natural air and the heat exchange air flow is more uniform. 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.
In some embodiments, the jet air duct 10 is disposed at the rear section 411 of the through channel 41, and the shape of the jet air duct 10 is adapted to the shape of the rear section 411 of the through channel, so that the structural layout between the jet air duct 10 and the through channel 41 is more compact to reduce the volume of the cabinet air conditioner indoor unit 1. The rear section 411 of the through channel 41 and the cross section of the jet air duct 10 are both tapered back to front, so that a flow guide cavity 11 which is tapered back to front is formed in the jet air duct 10, so that the natural air flows out quickly to the front.
Further, the jet duct 10 is arranged to be controllably or operatively moved in a front-rear direction to close the two induced air channels 44 when it is moved forward to bring its two transverse duct walls 10f into abutment with the two side walls 41a of the through-channel rear section 411, respectively, and to open the two induced air channels 44 when it is moved backward to bring a gap between its two transverse duct walls 10f and the two side walls 41a of the through-channel rear section 411, respectively. Since the rear section 411 of the through channel 41 and the jet air duct 10 are both tapered back to front, the distance between the two lateral air duct walls 10f and the two side walls 41a of the through channel rear section 411 is greater and greater, i.e. the flow area of the air induction channel 44 is greater and greater, as the jet air duct 10 moves backward. Conversely, as the jet duct 10 moves forward, the distance between the two lateral duct walls 10f and the two side walls 41a of the through-channel rear section 411 becomes smaller, that is, the flow area of the induced air channel 44 becomes smaller. When the jet duct 10 moves forward to a predetermined position, its two lateral duct walls 10f abut against the two side walls 41a of the through duct rear section 411, and the air-guiding duct 44 is completely closed. In this way, the flow area of the two induced air channels 44 can be adjusted by the back and forth movement of the jet flow duct 10, so as to adjust the amount of natural air introduced by the induced air channels 44.
In some embodiments, the cross-section of the jet duct 10 is trapezoidal in shape tapering from back to front. When the two air induction channels 44 are in a closed state, i.e., the two lateral air duct walls 10f of the jet air duct 10 abut against the two side walls 41a of the through channel rear section 411, the rearward facing surface 10e of the jet air duct 10 is flush with the rearward facing surface of the cabinet 40. When the cabinet air-conditioning indoor unit 1 is in the shutdown state, the induced air channel 44 can be controlled to be in the closed state to prevent dust and impurities from entering the casing 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 cabinet 40 further has a first air inlet 451 and a second air inlet 452, 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 first fan 61 causes the air outside the cabinet air conditioner indoor unit 1 to flow into the first heat exchange air duct 42 through the first air inlet 451, and the second fan 62 causes the air outside the cabinet air conditioner indoor unit 1 to flow into the second heat exchange air duct 43 through the second air inlet 452.
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 about the vertical bisection 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. The two air induction channels 44 may also be arranged symmetrically with respect to the vertical bisecting plane m of the housing 40 in the transverse 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 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 flow into the centrifugal fan horizontally and 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.
In some embodiments, the jet fan 20 is fixedly disposed below the jet stack 10, and the jet stack 10 is configured to controllably or operably move relative to the jet fan 20. That is, the jet fan 20 is stationary and the jet stack 10 is movable relative to the jet fan 20. At this time, the jet air duct 10 and the jet fan 20 may be connected by a hose capable of generating recoverable elastic deformation, and the arrangement of the hose may allow the jet air duct 10 and the jet fan 20 to generate relative displacement, and may also ensure a fluid communication relationship between the jet air duct 10 and the jet fan 20 with good sealing performance. In these embodiments, the cabinet air conditioner indoor unit 1 further includes a driving device for driving the jet duct 10 to move, and the driving device may be any available driving device, and will not be described herein.
In other embodiments, the jet fan 20 is fixedly connected to the jet stack 10, either directly or indirectly, and the jet stack 10 is controllably or operatively moved with the jet fan 20. That is, the jet fan 20 and the jet duct 10 cannot be displaced relative to each other, but they can be moved together. The connection mode between the jet air duct 10 and the jet fan 20 is not particularly required in this way, as long as a fluid communication relationship with good sealing performance between the two can be ensured. In these embodiments, the cabinet air conditioner indoor unit 1 further includes a driving device for driving the jet duct 10 and the jet fan 20 to move synchronously, and the driving device may be any available driving device, and will not be described herein again.
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. 7 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. 8 is a schematic enlarged view of a portion C in fig. 7, and fig. 9 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. 7 to 9, in some embodiments, a guide cavity 11 extending vertically is defined in the jet air duct 10, and the airflow 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 vertically extending arc-shaped guide plates 13 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 a tapered arc-shaped closing part 111 is formed at the front part of the guide cavity 11, which is close to the strip-shaped jet air outlet 12. That is, the arcuate mouth portion 111 tapers from back to front and is generally 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 10c. 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 flow guide cavity 11 thus formed includes an arc-shaped mouth portion 111 at the front and a trapezoid receptacle 112 at the rear, and the boundary between the trapezoid receptacle 112 and the arc-shaped mouth portion 111 is shown by a dotted line in fig. 9.
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. 9 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 direction 4 Is the width W of the jet flow air outlet 12 in the transverse direction 6 5 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 rearmost width of the diversion cavity 11Compare in the width of efflux air outlet 12 too big, can lead to the area at water conservancy diversion chamber 11 rear portion too big, the air current is far away from efflux air outlet 12 distance when flowing through water conservancy diversion chamber 11 rear portion, most air currents can directly flow upwards through the rear portion of water conservancy diversion chamber 11 this moment, the airflow that flows to efflux air outlet 12 is very few, this air output that leads to efflux air outlet 12 top is great, the air output of efflux air outlet 12 bottom and middle part is very little, the air-out of efflux air outlet 12 is very unbalanced. If the width of water conservancy diversion chamber 11 rearmost end is less with jet air outlet 12's width multiple, the width difference between the two is less, and the air current is not obvious by the acceleration effect that obtains when flowing forward backward, and jet air outlet 12's air-out speed and air supply distance are all smaller.
In some embodiments, the flow-guiding cavity 11 is tapered in cross-section in the direction from the rear to the front. Width W of rearmost end of flow guide cavity 11 in lateral direction 4 And the depth H of the diversion cavity 11 in the front and back directions 4 The ratio therebetween is any ratio in the range of 2. For example, width W 4 And depth H 4 The ratio between may be 2. 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 avoided 4 And depth H 4 Too small a ratio therebetween results in insufficient acceleration or width W of the air flow to the jet outlet 12 4 And depth H 4 The 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 direction 5 And the depth H of the diversion cavity 11 in the front and back directions 4 Any ratio in the range of 4. It can be understood that the length H of the arc-shaped baffle 13 in the front-rear direction 5 The front end and the rear end of the arc-shaped guide plate 13 are vertically spaced in the front-rear direction. For example, length H 5 And depth H 4 The ratio between may be 4. Thereby, on one hand, the rear part of the diversion cavity 11 can be ensuredThe area of the air flow entering the jet air duct 10 can be large, 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 air flow flowing from bottom to top can be accelerated well, and a large air outlet speed can be obtained. On the contrary, if the length H is long 5 And depth H 4 If 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 is 5 And depth H 4 If 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 direction 1 The length H of the arc-shaped guide plate 13 in the front-back direction is less than or equal to 5 So 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 of vertical interval arrangement along a plurality of in arc closing part 111 to make the air-out of efflux air outlet 12 on vertical side more even through arc closing part 111 and the cooperation of baffle 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 direction 3 A length W in the front-rear direction of the straight section 142 of not less than 2 . 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 air flow remained in the inner side of the guide vane 14 is too much due to the fact that the guide vane 14 located at the bottom extends backwards too long, so that the air flow at the top of the guide chamber 11 is less can be avoided, and meanwhile, the problem that the air flow 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 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 at equal intervals in sequence, so as to further ensure 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. 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.
Specifically, the volute duct 30 extends vertically. When only the jet air duct 10 is movable, the volute air duct 30 may be a soft air duct to generate a certain amount of elastic deformation. When the jet air duct 10 and the jet fan 20 move synchronously, the volute air duct 30 may be a hard air duct and moves synchronously with the jet air duct 10 and the jet fan 20.
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 arranged at the lower part of the inside of the casing 40, so that the jet fan 20 and the volute air duct 30 are prevented 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. A damper may be provided at the air intake grille 47 to controllably open and/or close the airflow inlet of the jet fan 20.
It should be further understood by those skilled in the art that the terms "upper", "lower", "front", "rear", and the like used in the embodiments of the present invention to indicate the orientation or the positional relationship are based on the actual use state of the cabinet air conditioner indoor unit 1, and these terms are only used for convenience of description and understanding of the technical solution of the present invention, and do not indicate or imply that the device referred to has to have a specific orientation, be configured and operated in a specific orientation, and therefore, should not be construed as limiting the present invention.
