Description

Technical Field

[0002] Air conditioners are devices used to adjust air temperature and are often used in indoor places such as homes or public places. In order to increase the air supply range or increase the air supply distance, some air conditioners in the related art usually set air guide plates or flow guide plates at the air outlet to guide the flow direction of the air flow, thereby increasing the air supply range or increasing the air supply distance. However, the air supply range or air supply distance can only be adjusted by setting air guide plates or flow guide plates, and the adjustment ability is limited, so further improvement of the air conditioner structure is urgently needed.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0066] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0067] Reference below Figure 1-Figure 21 The air conditioner 100 according to the embodiment of the present invention is described. The type of the air conditioner 100 is not limited here. It can be a cabinet or a mobile air conditioner, or other types of air conditioners 100.

[0068] like Figure 1-Figure 2 As shown, the air conditioner 100 according to the embodiment of the present invention includes a housing assembly 1 , a first fan 31 , a second fan 32 and a switching component 40 .

[0069] like Figure 3 and Figure 6 As shown, the housing assembly 1 has a first air outlet 11 and a second air outlet 12, and the first air outlet 11 and the second air outlet 12 are arranged at intervals. The housing assembly 1 also has a first channel 21 and a second channel 22, and the first channel 21 and the second channel 22 can convey airflow to the first air outlet 11, and the first channel 21 and the second channel 22 can also convey airflow to the second air outlet 12.

[0070] The first fan 31 may be in communication with the first channel 21 to drive airflow into the first channel 21 ; the second fan 32 may be in communication with the second channel 22 to drive airflow into the second channel 22 .

[0071] When the first fan 31 is running and the first air outlet 11 is open, the first fan 31 can form and drive the airflow to flow along the first channel 21, and the airflow is transported toward any one of the first air outlet 11 and the second air outlet 12. When the second fan 32 is running and the second air outlet 12 is open, the second fan 32 can form and drive the airflow to flow along the second channel 22, and the airflow is transported toward any one of the first air outlet 11 and the second air outlet 12.

[0072] It is worth noting that the relative position of the first fan 31 and the first channel 21 is not limited, for example, the first fan 31 can be located upstream, inside, or downstream of the first channel 21, and the relative position of the second fan 32 and the second channel 22 is not limited, for example, the second fan 32 can be located upstream, inside, or downstream of the second channel 22. To simplify the description, the following description will only take the case where the first fan 31 is located upstream of the first channel 21, that is, the outlet of the first fan 31 is connected to the inlet of the first channel 21, and the case where the second fan 32 is located upstream of the second channel 22, that is, the outlet of the second fan 32 is connected to the inlet of the second channel 22 as an example for description.

[0073] The switching component 40 of the air conditioner 100 can adjust the on-off of the air flow path, and has at least a first switching state and a second switching state. The ventilation area of ​​the first air supply port 11 in the first switching state is smaller than the ventilation area in the second switching state, and the ventilation area of ​​the second air supply port 12 in the first switching state is larger than the ventilation area in the second switching state. That is to say, in the first switching state, the airflow that can pass through the first air supply port 11 is reduced, while the airflow that can pass through the second air supply port 12 is increased; in the second switching state, the airflow that can pass through the first air supply port 11 is increased, while the airflow that can pass through the second air supply port 12 is reduced. As a result, the air conditioner 100 can switch different working modes to achieve a variety of air supply effects.

[0074] It is worth mentioning that the specific structure of the switching component 40 and which airflow path it is used to control can be flexibly designed according to the connection method between the first channel 21 and the first air supply port 11 and the second air supply port 12, and can also be flexibly designed according to the connection method between the second channel 22 and the first air supply port 11 and the second air supply port 12, and is not limited to one method.

[0075] In the first switching state, the switching component 40 switches, at which time the first fan 31 drives the airflow in the first channel 21 to flow toward the first air supply port 11 and the second air supply port 12, and the second fan 32 drives the airflow in the second channel 22 to flow toward the first air supply port 11 and the second air supply port 12. Due to the position setting of the switching component 40, the airflow that can pass through the first air supply port 11 is relatively reduced, and the airflow that can pass through the second air supply port 12 is relatively increased. In the second switching state, the switching component 40 switches, at which time the first fan 31 drives the airflow in the first channel 21 to flow toward the first air supply port 11 and the second air supply port 12, and the second fan 32 drives the airflow in the second channel 22 to flow toward the first air supply port 11 and the second air supply port 12. Due to the position setting of the switching component 40, the airflow that can pass through the first air supply port 11 is relatively increased, and the airflow that can pass through the second air supply port 12 is relatively reduced.

[0076] It should be noted that the change in the ventilation area of ​​the first air supply port 11 under different switching states is a comparison of the change in the ventilation area of ​​the first air supply port 11 itself. When the ventilation area of ​​the first air supply port 11 increases, the air volume allocated increases, and when the ventilation area of ​​the first air supply port 11 decreases, the air volume allocated decreases. In the first switching state, the ventilation area of ​​the first air supply port 11 is small, and can even be zero, that is, the first air supply port 11 can be completely closed in the first switching state. In each switching state, the size relationship between the ventilation areas of the first air supply port 11 and the second air supply port 12 is not limited. The ventilation area of ​​the first air supply port 11 can be larger than the ventilation area of ​​the second air supply port 12, so that the air volume allocated by the first air supply port 11 can be more than the air volume allocated by the second air supply port 12. The ventilation area of ​​the first air supply port 11 can also be smaller than the ventilation area of ​​the second air supply port 12, so that the air volume allocated by the first air supply port 11 can be less than the air volume allocated by the second air supply port 12.

[0077] Similarly, the change in the ventilation area of ​​the second air supply port 12 under different switching states is compared with the change in the ventilation area of ​​the second air supply port 12 itself. When the ventilation area of ​​the second air supply port 12 increases, the air volume allocated increases, and when the ventilation area of ​​the second air supply port 12 decreases, the air volume allocated decreases. In the second switching state, the ventilation area of ​​the second air supply port 12 is small, and can even be zero, that is, the second air supply port 12 can be completely closed in the second switching state. In each switching state, there is no restriction on the size relationship between the ventilation areas of the second air supply port 12 and the first air supply port 11. The ventilation area of ​​the second air supply port 12 can be larger than the ventilation area of ​​the first air supply port 11, so that the air volume allocated by the second air supply port 12 can be more than the air volume allocated by the first air supply port 11. The ventilation area of ​​the second air supply port 12 can also be smaller than the ventilation area of ​​the first air supply port 11, so that the air volume allocated by the second air supply port 12 can be less than the air volume allocated by the first air supply port 11.

[0078] The air conditioner 100 of the present application can obtain multiple operating modes through the switching component 40 and the combined structure of the first fan 31 and the second fan 32. In each mode, not only the air supply range can be changed, the distribution ratio of the air supply volume in different air supply outlets can be changed, and the total air supply volume of the air conditioner 100 can also be changed.

[0079] For example, when a large area of ​​air supply is required, combined with Figure 4-Figure 6 As shown, the switching component 40 is in the first switching state, the first fan 31 and the second fan 32 are both working, the airflow that can pass through the first air supply port 11 is reduced, and the airflow that can pass through the second air supply port 12 is increased, thereby presenting a large-scale air supply effect through the second air supply port 12.

[0080] For example, when long-distance air supply is required, combined with Figure 7-Figure 9As shown, the switching component 40 is in the second switching state, the first fan 31 and the second fan 32 are both working, the airflow that can pass through the first air supply port 11 increases, while the airflow that can pass through the second air supply port 12 decreases, thereby presenting a long-distance air supply effect through the first air supply port 11.

[0081] For example, when the normal air supply is in the third switching state, any one of the first fan 31 and the second fan 32 can be turned on, and the other fan can be turned off. At this time, the airflow can pass through the first channel 21 or the second channel 22 and be delivered from at least one of the first air supply port 11 and the second air supply port 12, thereby reducing energy consumption and meeting daily ventilation needs.

[0082] The present application is not limited thereto. For example, in a further embodiment, the switching component 40 is in the first switching state, and the switching component 40 completely closes the first air supply port 11, and the airflows formed by the first fan 31 and the second fan 32 all flow toward the second air supply port 12, and a wide range of air supply can be achieved. In the first switching state, the first air supply port 11 is closed, and there is no diversion of the first air supply port 11. The airflow that can pass through the second air supply port 12 is greater than the airflow of the second air supply port 12 in the second switching state, thereby achieving a wide range of air supply and enhancing the wind force.

[0083] For another example, when long-distance air supply is required, the switching component 40 is switched to the second switching state, the second air supply port 12 is completely closed, and the airflow formed by the first fan 31 and the second fan 32 flows toward the first air supply port 11. Since there is no diversion at the second air supply port 12, the first air supply port 11 can achieve longer-distance blowing at this time. The first air supply port 11 not only has a large air supply volume but also has a strong wind force.

[0084] According to the air conditioner 100 of the embodiment of the present invention, by setting the first fan 31 and the second fan 32 to be connected to the first channel 21 and the second channel 22, the air volume of the first air supply port 11 and the second air supply port 12 can be adjusted and the air flow direction can be distributed by adjusting the on-off of the air flow path by the switching component 40, so as to realize long-distance air supply or large-scale air supply, so as to provide more air supply effect options. And whether it is large-scale air supply or long-distance air supply, since the first fan 31 and the second fan 32 are used at the same time, the air supply volume and the air supply wind force can be adjusted and changed. Moreover, the structure of the air conditioner 100 is relatively simple and easy to manufacture.

[0085] like Figure 3 , Figure 6 , Fig. 9 and Fig.14As shown, in some embodiments, the housing assembly 1 includes a first air mixing duct 23. The first air mixing duct 23 has a first inlet 231 and a second inlet 232. The first inlet 231 is connected to the first channel 21, the second inlet 232 is connected to the second channel 22, and the outlet of the first air mixing duct 23 is connected to the first air supply port 11 and the second air supply port 12. That is, the wind in the first channel 21 and the wind in the second channel 22 converge to the first air mixing duct 23, and then are directed to the first air supply port 11 and the second air supply port 12 according to the state of the switching component 40.

[0086] The setting of the first air mixing duct 23 allows the airflow output by the first fan 31 and the second fan 32 to mix in the first air mixing duct 23, which helps to make the air volume and wind force distribution more uniform. Taking the air outlet of the second air supply port 12 as an example, when the first fan 31 and the second fan 32 are turned on at the same time, the air output of the two fans is mixed in the first air mixing duct 23 and then sent to the second air supply port 12, avoiding the unevenness of the second air supply port 12 facing the first fan 31 with less air volume and the second air supply port 12 facing the second fan 32 with more air volume. Moreover, when the first fan 31 is turned on and the second fan 32 is turned off, the setting of the first air mixing duct 23 causes the second air supply port 12 to produce changes in air volume and wind force, without causing the unevenness of no wind or too little wind force in the area where the second air supply port 12 faces the second fan 32.

[0087] Here, the first channel 21 is provided to adapt to the characteristics of the first fan 31. The first channel 21 is used to guide the air outlet of the first fan 31 to the first air supply port 11 and the second air supply port 12, and reduce air leakage, and maintain the positive air supply pressure of the first air supply port 11 and the second air supply port 12. Similarly, the second channel 22 is provided to adapt to the characteristics of the second fan 32. The second channel 22 is used to guide the air outlet of the second fan 32 to the first air supply port 11 and the second air supply port 12, and reduce air leakage, and maintain the positive air supply pressure of the first air supply port 11 and the second air supply port 12. The structural design of the first channel 21 and the second channel 22 can be adapted to the air outlet characteristics of the first fan 31 and the second fan 32 respectively. The setting of the first mixing air duct 23 is to be adapted to the air supply characteristics of the first air supply port 11 and the second air supply port 12. It can not only mix the airflow of the first channel 21 and the second channel 22 to make the air outlet more uniform, but also provide at least partial activity space for the operation of the switching component 40, so as to facilitate the change of airflow distribution under different switching states.

[0088] Specifically, the switching component 40 includes a first switching device 41 and a second switching device 42. The first switching device 41 can adjust the ventilation area of ​​the first air outlet 11, and the second switching device 42 can adjust the ventilation area of ​​the second air outlet 12. In this way, the ventilation areas of the first air outlet 11 and the second air outlet 12 are adjusted separately, which not only greatly reduces the difficulty of structural design, but also facilitates the layout of the positions of the first switching device 41 and the second switching device 42 according to the positions of the first air outlet 11 and the second air outlet 12. Moreover, the first switching device 41 and the second switching device 42 do not need to be linked, that is, the state of the first switching device 41 and the state of the second switching device 42 can be combined to obtain more state modes, so that the air conditioner 100 can obtain more operating modes to meet the diverse needs of users.

[0089] Of course, the present application solution may not be limited thereto. For example, the switching component 40 does not need to be divided into a first switching device 41 and a second switching device 42, and the switching component 40 is located at the outlet of the first air mixing duct 23. In the first switching state, the switching component 40 moves toward the outlet connected to the first air supply port 11, and the switching component 40 blocks the passage toward the first air supply port 11, thereby reducing the ventilation area of ​​the first air supply port 11. In the second switching state, the switching component 40 moves toward the outlet connected to the second air supply port 12, and the switching component 40 blocks the passage toward the second air supply port 12, thereby reducing the ventilation area of ​​the second air supply port 12. Although there are fewer adjustment modes, the basic mode requirements of long-distance air supply and large-range air supply can be met.

[0090] In some specific embodiments, the second air supply port 12 includes two. Figure 1 , Figure 3 , Figure 6 , Fig. 9 and Fig.14 In the example shown in , each second air outlet 12 is along, and the two second air outlets 12 can be arranged on both sides of the air conditioner 100 along the second direction D2.

[0091] Correspondingly, the first air mixing duct 23 includes two, and the two first air mixing ducts 23 and the two second air supply ports 12 can be respectively arranged in correspondence. One first air mixing duct 23 is used to mix part of the air output of the first fan 31 and part of the air output of the second fan 32, and then the mixed air flow can be blown out from the first air supply port 11 or from a second air supply port 12. Another first air mixing duct 23 is used to mix part of the air output of the first fan 31 and part of the air output of the second fan 32, and then the mixed air flow can be blown out from the first air supply port 11 or from another second air supply port 12. Such an arrangement is to make the air distribution of the two second air supply ports 12 smoother when there are two second air supply ports 12.

[0092] Specifically, the two first air mixing ducts 23 are located on both sides of the second channel 22, and each first air mixing duct 23 has a second inlet 232 connected to the second channel 22, so the second channel 22 can be connected to the two first air mixing ducts 23 through the two second inlets 232. As a result, the air outlet of the second fan 32 is split at the outlet of the second channel 22 and distributed to the two first air mixing ducts 23.

[0093] For example, the second fan 32 can be a crossflow fan, which is extended along the first direction D1. A crossflow fan is used, and the crossflow fan has a smaller area on a plane perpendicular to the first direction D1. The crossflow fan is a slender cylinder with a compact structure and occupies a small space. In addition, the crossflow fan has high efficiency, low energy consumption, low noise, and is easy to install. Some crossflow fans have adjustable blade angles, and the wind speed and air volume can be adjusted according to actual needs. Compared with centrifugal fans and axial flow fans, the wind force of crossflow fans is relatively soft, which can reduce the feeling of direct wind.

[0094] In addition, the matching of the cross-flow fan and the second air supply port 12 also helps to make the air supply of the second air supply port 12 relatively uniform over the entire length range of the first direction D1.

[0095] Specifically, the first channel 21 includes two branch channels 210, and the outlets of the two branch channels 210 are respectively connected to the first inlets 231 of the two first air mixing ducts 23. Thus, each first air mixing duct 23 can introduce air from two fans through the first inlet 231 and the second inlet 232, and the airflow can be respectively delivered to the second air supply port 12 through the outlets of the first air mixing duct 23.

[0096] Of course, the present application solution may not be limited to the solution of the above two second air supply ports 12. In the above embodiment, when there are two second air supply ports 12, the two second air supply ports 12 are arranged on both sides of the air conditioner 100 along the second direction D2, and the first air mixing ducts 23 are two corresponding to each other. There may also be only one second air supply port 12, and one second air supply port 12 is arranged in the middle position of the air conditioner 100 in the second direction D2. The first air mixing duct 23 is adjusted according to the internal structure of the air conditioner 100, and the first air mixing duct 23 may include one.

[0097] like Fig.19As shown, in some embodiments, the first fan 31 is a centrifugal fan, which includes a volute 311, two branch channels 210 connecting the expansion section 312 of the volute 311, and the two branch channels 210 are sequentially distributed along the circumference of the volute 311. Compared with distributing the two branch channels 210 along the axial direction of the volute 311, it is easier to distribute the outlet air to different branch channels 210 when distributing along the circumferential direction, and the energy consumption is lower when distributing the air. Moreover, such a design is conducive to the flattening design of the overall first fan 31 and the two branch channels 210, which helps to reduce the occupied space.

[0098] Moreover, since the air conditioner 100 is not limited to the first channel 21, but also has the second channel 22 and the first mixed air duct 23, after the first channel 21 is divided into two sub-channels 210, not only the air outlet of the first fan 31 is directed to the two first mixed air ducts 23, but also the space between the two sub-channels 210 can be utilized for arranging the second channel 22. This can improve the compactness and rationality of the arrangement of each channel and duct in the shell assembly 1.

[0099] like Fig.19 As shown, the expansion section 312 has a first side wall 313 and a second side wall 314, the first side wall 313 and the second side wall 314 are opposite, the first side wall 313 is connected to the volute tongue 315 of the volute 311, and the first side wall 313 of the two sub-channels 210 is the first sub-channel 211, and the second side wall 314 is the second sub-channel 212. Through the expansion section 312 of the centrifugal fan, the air outlet of the centrifugal fan is enlarged, so that the air formed by the centrifugal fan can flow through the first sub-channel 211 and the second sub-channel 212 to reach the first air supply port 11 and the second air supply port 12.

[0100] For example, compared with some other types of fans, the centrifugal fan has the characteristics of large air volume and strong wind force. In the second switching state, the area of ​​the first air supply port 11 increases, and the airflow blown out by the centrifugal fan enters the first channel 21, is distributed to the first sub-channel 211 and the second sub-channel 212, and flows to the first air supply port 11, which can blow the airflow farther.

[0101] For example, the first air outlet 11 extends along the second direction D2, and the second air outlet 12 extends along the first direction D1. In this way, when both the first air outlet 11 and the second air outlet 12 discharge air, the air supply area is further expanded.

[0102] Optionally, the first air outlet 11 may be located at the upper front end of the air conditioner 100, and the first air outlet 11 supplies air forward. The first air outlet 11 may also be located at the top of the air conditioner 100, and the first air outlet 11 supplies air upward. Further optionally, when the first air outlet 11 is located at the top of the air conditioner 100, the air outlet direction of the first air outlet 11 has a certain inclination angle relative to the vertical line, so that the first air outlet 11 supplies air obliquely upward.

[0103] like Fig.19 As shown, in some specific embodiments, the flow area of ​​the first sub-channel 211 is smaller than the flow area of ​​the second sub-channel 212. It can be understood that, according to the air outlet characteristics of the centrifugal fan, the second sub-channel 212 separated from the volute tongue 315 has a smaller air outlet resistance than the first sub-channel 211 close to the volute tongue 315, and it is easier to distribute more air outlet. Therefore, the flow area of ​​the first sub-channel 211 is set to be smaller than the flow area of ​​the second sub-channel 212, so that the air outlet volume matches the flow area of ​​the two sub-channels 210, which can improve the channel space utilization rate.

[0104] The second channel 22 and the first air mixing duct 23 are also arranged in the space where the first sub-channel 211 and the second sub-channel 212 are located. In some schemes, the second fan 32 is a cross-flow fan and is also arranged in this space. The air outlet characteristics of the cross-flow fan determine the shape of the second channel 22, which is wide on one side and thin on the other side in the second direction D2. At this time, the first sub-channel 211 is set to be thin and the second sub-channel 212 is set to be wide, the wide second sub-channel 212 is arranged on the thin side of the second channel 22, and the thin first sub-channel 211 is arranged on the wide side of the second channel 22, so that the overall channel layout is more reasonable.

[0105] Optionally, each sub-channel 210 is extended along the first direction D1, and has a dimension along the second direction D2, and the dimension of the sub-channel 210 in the second direction D2 is the width of the sub-channel 210. The sub-channel 210 also has a dimension in a third direction perpendicular to both the first direction D1 and the second direction D2, and the dimension is the thickness of the sub-channel 210. The thickness of the first sub-channel 211 and the thickness of the second sub-channel 212 are substantially equal, and the difference is that, as Fig.19 As shown, the width L1 of the first sub-channel 211 is smaller than the width L2 of the second sub-channel 212 , so that the flow area of ​​the first sub-channel 211 is smaller than the flow area of ​​the second sub-channel 212 .

[0106] Specifically, Fig.19 As shown, the first air supply port 11 and the first fan 31 are located at both ends of the first channel 21 in the first direction D1. Specifically, the first fan 31 needs to form and drive the airflow to flow through the first air supply port 11 along the first direction D1, and the airflow needs to overcome resistance such as gravity. The airflow path is that the first fan 31 forms the airflow to the first channel 21, and under the diversion of the shell component 1, it is transmitted to the first air supply port 11 along the first branch channel 211 and the second branch channel 212 respectively. The first branch channel 211 and the second branch channel 212 are arranged on both sides of the air conditioner 100 along the second direction D2, thereby guiding the airflow to flow out from the end of the first air supply port 11 along the second direction D2.

[0107] Furthermore, if Fig.19 and Fig.21 As shown, the housing assembly 1 is provided with a plurality of flow dividers 14 between the first channel 21 and the first air outlet 11 to redistribute uneven airflow so that the airflow from the first air outlet 11 is relatively uniform. The flow dividers 14 can also guide the airflow, reduce the vortex generated when the airflow converges and turns, and reduce the air loss.

[0108] like Fig.19 and Fig.21 As shown, in some specific embodiments, the diverter plate 14 is tilted relative to the first direction D1, and in the air outlet direction, the diverter plate 14 is tilted toward the center of the first air outlet 11. Thus, the tilted diverter plate 14 can help distribute the airflow toward the center of the first air outlet 11, avoid the airflow being distributed only at the two ends of the first air outlet 11, and improve the uniformity of the air outlet.

[0109] By way of example, the flow divider 14 includes at least two, wherein at least two flow dividers 14 are respectively arranged at the outlets of the first sub-channel 211 and the second sub-channel 212. In some specific examples, the flow divider 14 includes five, wherein two flow dividers 14 are arranged at the outlet of the first sub-channel 211, and the other two flow dividers 14 are arranged at the outlet of the second sub-channel 212. The flow divider 14 at the outlet of the first sub-channel 211 is inclined toward the side where the second sub-channel 212 is located in the air outlet direction. The flow divider 14 at the outlet of the second sub-channel 212 is inclined toward the side where the first sub-channel 211 is located in the air outlet direction.

[0110] Further, as shown in FIG21 , the inclination angle of the diverter plate 14 corresponding to the first branch channel 211 relative to the first direction D1 is A1, and the inclination angle of the diverter plate 14 corresponding to the second branch channel 212 relative to the first direction D1 is A2, and A1 is smaller than A2.

[0111] It can be understood that since the airflow distributed by the second sub-channel 212 is greater than the airflow distributed by the first sub-channel 211, the inclination angle A2 of the diverter plate 14 corresponding to the second sub-channel 212 is set to be larger, which helps to guide more airflow in the second sub-channel 212 to the middle position of the first air supply port 11, and further helps to uniformly distribute the air outlet from the first air supply port 11.

[0112] For example, Fig.21 For example, the first branch channel 211 and the second branch channel 212 are arranged to extend vertically, the first branch channel 211 is thinner and located on the right, and the second branch channel 212 is wider and located on the left. A plurality of diverter plates 14 are distributed from left to right on the top of the first channel 21. Some of the diverter plates 14 are on the left and located above the second branch channel 212. Some of the diverter plates 14 are on the right and located above the first branch channel 211.

[0113] The left flow divider 14 is tilted to the right in the upward direction, so that the left flow divider 14 helps to guide the airflow of the second sub-channel 212 to flow upward and also guide the airflow of the second sub-channel 212 to be distributed to the right. The right flow divider 14 is tilted to the left in the upward direction, so that the right flow divider 14 helps to guide the airflow of the first sub-channel 211 to flow upward and also guide the airflow of the first sub-channel 211 to be distributed to the left. In this way, multiple flow dividers 14 help to evenly distribute the airflow in the left-right direction.

[0114] The second branch channel 212 on the left is wider, and the corresponding flow dividing plate 14 is inclined to the right at an angle of A2 relative to the vertical line. The first branch channel 211 on the right is thinner, and the corresponding flow dividing plate 14 is inclined to the left at an angle of A1 relative to the vertical line. A2>A1, so that the flow dividing plate 14 of the branch channel 10 with a large air flow can distribute more airflow to the center of the first air supply port 11.

[0115] Furthermore, in a row of diverter plates 14, the diverter plate 14 located at the center may not be inclined relative to the first direction D1, that is, the diverter plate 14 may be parallel to the first direction D1, so that the air flow is directly guided to the center of the first air supply port 11, reducing air flow reversal.

[0116] In some specific embodiments, when the first channel 21 includes at least one branch channel 210, there may be one or two first air mixing ducts 23. The branch channel 210 is located on one side of the first air mixing duct 23 in the horizontal direction, so that the air outlet of the branch channel 210 can enter the first air mixing duct 23 through the first inlet 231 in the horizontal direction.

[0117] When the second air supply port 12 is open and the first fan 31 is running, the airflow in the sub-channel 210 enters the first air mixing duct 23 and then blows out from the second air supply port 12. When the first air supply port 11 is open, the airflow in the sub-channel 210 can enter the first air mixing duct 23 and then blow out from the first air supply port 11, and the airflow in the sub-channel 210 can flow directly from the top to the first air supply port 11. When both the first air supply port and the second air supply port 12 are open and the first fan 31 is running, part of the airflow in the sub-channel 210 enters the first air mixing duct 23 and flows to the second air supply port 12, and part of the airflow flows from the top to the first air supply port 11.

[0118] like Figure 1 and Fig. 9 As shown, in some embodiments, the first air outlet 11 is located above the second air outlet 12, that is, Figure 1 The first direction D1 shown is the up-down direction.

[0119] The housing assembly 1 includes a second air mixing duct 24, which is located above the first air mixing duct 23. The lower end of the second air mixing duct 24 is connected to the first air mixing duct 23 and the first channel 21, and the upper end of the second air mixing duct 24 is connected to the first air supply port 11.

[0120] The second air mixing duct 24 is provided so that when the first air supply port 11 is opened, the airflows from the other air ducts converge into the second air mixing duct 24, and after being mixed in the second air mixing duct 24, flow toward the first air supply port 11. By connecting the lower end of the second air mixing duct 24 with the first air mixing duct 23 and the first channel 21, the airflow of the first channel 21 can flow directly from above to the second air mixing duct 24, and the airflow of the first air mixing duct 23 can also flow directly from above to the second air mixing duct 24.

[0121] In some solutions, the lower end of the second air mixing duct 24 is also connected to the second channel 22, and the airflow of the second channel 22 can flow directly from the top to the second air mixing duct 24. This arrangement shortens the air supply path to the first air supply port 11, which is conducive to reducing air loss. Through the second air mixing duct 24, the airflow in the first channel 21, the second channel 22 and the first air mixing duct 23 can be guided to flow through the first air supply port 11, thereby realizing long-distance air supply.

[0122] Specifically, the splitter plate 14 is disposed in the second air mixing duct 24, so that the airflow entering the second air mixing duct 24 from different air ducts below can be guided through the splitter plate 14, which is helpful to reduce the turbulence generated when the airflow is mixed.

[0123] For example, the air flow area of ​​the first air supply port 11 is smaller than the air flow area of ​​the air inlet of the second air mixing duct 24, thereby compressing the air flow, increasing the flow rate of the air flow, and achieving air supply over a longer distance.

[0124] like Fig. 9 and Fig. 20 As shown, in some embodiments, the second air mixing duct 24 includes a tapered section 241, and the flow area of ​​the tapered section 241 gradually decreases in the direction toward the first air supply port 11. The airflow formed by the first fan 31 and the second fan 32 overcomes gravity, and when the airflow passes through the second air mixing duct 24 and flows toward the first air supply port 11 above, it will pass through the tapered section 241. On the one hand, the airflow can be compressed, the flow rate of the airflow can be increased, and the airflow can be blown farther; on the other hand, the gradual reduction of the flow area is conducive to reducing airflow turbulence and reducing the air volume loss caused by the reduction of the airflow flow area.

[0125] like Fig. 9 and 20As shown, in some specific embodiments, the second air mixing duct 24 includes a straight section 242 connected between the tapered section 241 and the first air supply port 11, and the flow area of ​​the straight section 242 in the air outlet direction remains unchanged. By setting the straight section 242, the airflow is more stable at the outlet position.

[0126] like Figure 6 , 9 and Fig.17 As shown, in some embodiments, the switching component 40 includes a first switching device 41, which is disposed at the first air outlet 11, and includes a rotating door 412, which rotates to close the first air outlet 11 or to open the first air outlet 11. By providing the rotating door 412, the rotating door 412 rotates to gradually open or gradually close the first air outlet 11, thereby achieving a variety of air supply effects.

[0127] like Fig.17 As shown, exemplarily, the first switching device 41 further includes a first driver 411 , which can drive the rotating door 412 to rotate, and the first driver 411 is installed on the housing assembly 1 .

[0128] like Fig.17 As shown, in some embodiments, the housing assembly 1 includes a cylindrical cavity 15, and a first air supply port 11 is formed on the wall surface of the cylindrical cavity 15. The rotating door 412 is cylindrical and fits in the cylindrical cavity 15, and a rotating cavity 413 is formed in the rotating door 412. In the first switching state, the rotating cavity 413 is directly opposite to the wall surface of the cylindrical cavity 15 to close the first air supply port 11. In the second switching state, the rotating cavity 413 is arranged directly opposite to the first air supply port 11 to fully open the first air supply port 11. By setting the cylindrical cavity 15 and the rotating door 412 to be cylindrical, the adaptability of the two can be improved, that is, the rotating door 412 is convenient to rotate and reduce the stuck fault. The rotating door 412 of this structure can not only fully open the first air supply port 11, but also partially open the first air supply port 11, and can maintain a stable state when the first air supply port 11 is partially opened. The rotating door 412 of this structure is convenient for obtaining more control modes.

[0129] In the present application, the rotating door 412 is set to be cylindrical. When the parking angle of the rotating door 412 changes, the rotating door 412 can also adjust the direction of the airflow, so that while adjusting the ventilation area of ​​the first air supply port 11, the air supply direction of the first air supply port 11 can also be adjusted.

[0130] like Figure 6 and Fig. 9As shown, in some embodiments, the switching component 40 includes a second switching device 42, which is disposed at the second air outlet 12, and includes a guide vane 422, which can rotate to adjust the air outlet direction of the second air outlet 12. By providing the rotatable guide vane 422, on the one hand, the air flow direction, that is, the air outlet direction of the second air outlet 12 is guided; on the other hand, the rotation of the guide vane 422 can shield the second air outlet 12 to different degrees, thereby controlling the air outlet volume of the second air outlet 12.

[0131] like Figure 6 , Fig. 9 , Fig.11 and Fig.15 As shown, in some embodiments, the air guide blade 422 is provided with a through hole 428, through which air can pass. In the second switching state, the air guide blade 422 is parallel to the surface where the second air supply port 12 is located. Fig. 9 The guide blade 422 is parallel to the surface of the second air supply port 12. The guide blade 422 reduces the air flow area of ​​the second air supply port 12. The air flow is discharged through the through hole 428 on the guide blade 422. At this time, the guide blade 422 shields the second air supply port 12, and more air flows to the first air supply port 11 to achieve long-distance air supply. Under the action of the through hole 428 of the guide blade 422, the air outlet at the second air supply port 12 can reduce the wind feeling, and may even reach a state of no wind feeling.

[0132] Specifically, in the second switching state, the air guide blade 422 is parallel to the surface where the second air outlet 12 is located. Fig. 9 The guide blade 422 is parallel to the surface of the second air supply port 12, and the guide blade 422 reduces the air flow area of ​​the second air supply port 12. The air flows out through the through hole 428 on the guide blade 422. At this time, the guide blade 422 shields the second air supply port 12, and more air flows to the first air supply port 11, and the rotating door 412 of the first air supply port 11 is fully opened to realize long-distance air supply.

[0133] For example, in the first switching state, the air guide blade 422 is perpendicular to the surface of the second air outlet 12, increasing the gas flow area of ​​the second air outlet 12; at this time, the rotating door 412 rotates to reduce the gas flow area of ​​the first air outlet 11 until the first air outlet 11 is completely closed. Therefore, in the first switching state, air flows out from the left and right sides of the air conditioner 100, and air can be supplied over a wide range.

[0134] like Figure 11-Figure 15As shown, in some embodiments, the second switching device 42 includes a plurality of guide blades 422, and the guide blades 422 are sequentially distributed along the first direction D1. Each guide blade 422 has a rotating shaft 423 and a connecting shaft 424, and the rotating shaft 423 is connected to the inner wall of the second air supply port 12 and the rotating shaft 423 can pivot relative to the inner wall of the second air supply port 12. The second switching device 42 also includes a connecting rod 425, an adjusting motor 421, and a crankshaft 426. The connecting rod 425 is arranged along the first direction D1 and connected to the connecting shafts 424 of the plurality of guide blades 422, and the adjusting motor 421 is connected to the connecting rod 425 through the crankshaft 426. Specifically, the air guide vane 422 is connected to the housing assembly 1 through a connecting shaft 424 and a rotating shaft 423, the connecting shaft 424 is connected to the inner wall of the second air outlet 12, and multiple connecting shafts 424 are connected to the inner wall of the second air outlet 12 to form a connecting shaft 424 line; the rotating shaft 423 is connected to the connecting rod 425, wherein the connecting rod 425 and the connecting shaft 424 line are two straight lines. When the connecting rod 425 performs a planar motion under the action of the regulating motor 421, one end of all the air guide vanes 422 is driven to rotate, and the other end of the air guide vane 422 is fixed to the connecting shaft 424, thereby realizing the simultaneous rotation of multiple air guide vanes 422.

[0135] Specifically, Fig.15 As shown, the housing assembly 1 is also provided with a motor slot 16, and the regulating motor 421 is located in the motor slot 16. The second switching device 42 also includes a pressing plate 427, which is connected to the motor slot 16, and one end of the connecting rod 425 is clamped between the pressing plate 427 and the crankshaft 426. By providing the pressing plate 427, the stability and reliability of the connection can be improved.

[0136] Described below Figure 1-Figure 21 The structure of an air conditioner 100 in a specific embodiment is shown.

[0137] The air conditioner 100 is a cabinet air conditioner, and the length direction of the housing assembly 1 is arranged along the first direction D1, and the first direction D1 is the up-down direction. The length direction of the second air outlet 12 is arranged along the second direction D2, such as Figure 1 The second direction D2 is the left-right direction. There is one second air supply port 12 located at the front side of the air conditioner 100, and there are two second air supply ports 12 located at the left and right sides of the front side of the air conditioner 100. The first air supply port 11 is higher than the second air supply port 12, and the first air supply port 11 is located at the top surface or the upper front side of the air conditioner 100. The first fan 31 is a centrifugal fan, and the second fan 32 is a cross-flow fan.

[0138] like Figure 2As shown, the air conditioner 100 includes a housing assembly 1, and the housing assembly 1 includes a rear box 17 and a panel member 13 that are interlocked, and an installation space is formed between the two to install the functional parts of the air conditioner 100. Specifically, the rear box 17 includes a base 171, a top cover 172 and an air inlet grille 173, and the air inlet grille 173 is connected between the base 171 and the top cover 172. Optionally, the base 171, the top cover 172, the air inlet grille 173, and the air inlet grille 173 of the rear box 17 can be integrally processed and formed.

[0139] like Figure 2 As shown, the air conditioner 100 includes a panel member 13 having openings penetrating through the thickness thereof, which respectively constitute a first air supply port 11 and a second air supply port 12 .

[0140] like Figure 2 and Figure 3 As shown, the heat exchange component 7, the shell of part of the second fan 32 and the air duct assembly 5 form a first air outlet frame 51, the first air outlet frame 51 includes a first channel 21, a second channel 22 and a first air mixing duct 23, and the second air outlet frame 52 of the air duct assembly 5 includes a second air mixing duct 24.
