[0048] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. 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.

[0049] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present invention provides various specific processes and examples of materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0050] Hereinafter, with reference to the accompanying drawings, an air outlet structure 100 according to an embodiment of the present invention will be described.

[0051] like Figure 1-Figure 3 As shown, the air outlet structure 100 includes a housing 1, the housing 1 has a first air duct 11 and a second air duct 12 arranged at intervals, the first air duct 11 and the second air duct 12 are suitable for being connected to different fan components 102 respectively, and the housing 1 also has a first air outlet 13 and a second air outlet 14, the first air outlet 13 is connected to the first air duct 11, and the second air outlet 14 is connected to the second air duct 12. In this way, when the first air outlet 13 is opened, the fan component 102 connected to the first air duct 11 works, and an airflow is formed in the first air duct 11 and transported toward the first air outlet 13; when the second air outlet 14 is opened, the fan component 102 connected to the second air duct 12 works, and an airflow is formed in the second air duct 12 and transported toward the second air outlet 14; it can be seen that the air outlet structure 100 of the embodiment of the present application can realize independent air supply in the first air duct 11 and the second air duct 12 respectively.

[0052] The air outlet directions of the first air outlet 13 and the second air outlet 14 are different, so that the air supply airflows blown out of the first air outlet 13 and the second air outlet 14 intersect, and the air outlet direction of the first air outlet 13 and the air outlet direction of the second air outlet 14 intersect, so that the air supply path at the first air outlet 13 intersects with the air supply path at the second air outlet 14, so that the air supply airflow blown out of the first air outlet 13 and the air supply airflow blown out of the second air outlet 14 intersect. In this way, the air supply airflow of the first air outlet 13 and the air supply airflow of the second air outlet 14 merge to form a mixed air supply airflow, thereby, by changing the speed of the air supply airflow of the first air outlet 13 and / or the speed of the air supply airflow of the second air outlet 14, the airflow direction of the mixed air supply airflow can be changed, and then the air supply direction of the mixed air supply airflow can be adjusted, thereby, air supply effects such as directional air supply and sweeping air can be achieved.

[0053] It is worth noting that, for the convenience of the following description, the airflow delivered from the first air outlet 13 is the first supply air flow 10a, the airflow delivered from the second air outlet 14 is the second supply air flow 10b, and the first supply air flow 10a of the first air outlet 13 and the second supply air flow 10b of the second air outlet 14 merge into a mixed supply air flow 10c, as an example for explanation.

[0054] It can be understood that the air supply direction of the first supply air flow 10a of the first air outlet 13 and the air supply direction of the second supply air flow 10b of the second air outlet 14 remain unchanged. When the first air outlet 13 and the second air outlet 14 supply air together, the air flow velocity of the first supply air flow 10a and / or the air flow velocity of the second supply air flow 10b are adjusted, for example, the air flow velocity of the first air duct 11 and / or the air flow velocity of the second air duct 12 are adjusted (for example, the rotation speed of the fan component 102 connected to the first air duct 11 and / or the rotation speed of the fan component 102 connected to the second air duct 12) to achieve the adjustment of the air flow direction of the actual supply air flow 10c. For example, the air flow direction of the actual supply air flow 10c can be adjusted between the air flow direction of the first supply air flow 10a and the air flow direction of the second supply air flow 10b before the air flows converge.

[0055] Below, taking the example of adjusting the airflow velocity of the first air duct 11 and / or the airflow velocity of the second air duct 12 to achieve the adjustment of the airflow velocity of the first supply air airflow 10a and / or the airflow velocity of the second supply air airflow 10b, those skilled in the art will easily understand the implementation plan of adjusting the airflow velocity of the first supply air airflow 10a and / or the airflow velocity of the second supply air airflow 10b by other means after reading the following description.

[0056] When the airflow velocity of the second air duct 12 remains unchanged, the airflow velocity of the first air supply airflow 10a delivered from the first air outlet 13 can be changed by adjusting the airflow velocity in the first air duct 11, so that the air supply direction of the actual air supply airflow 10c can be close to or away from the air supply direction of the second air supply airflow 10b, thereby changing the air supply direction of the actual air supply airflow 10c. Similarly, when the airflow velocity of the first air duct 11 remains unchanged, the airflow velocity of the second air supply airflow 10b delivered from the second air outlet 14 can be changed by adjusting the airflow velocity in the second air duct 12, so that the air supply direction of the actual air supply airflow 10c can be close to or away from the air supply direction of the first air supply airflow 10a, thereby changing the air supply direction of the actual air supply airflow 10c. Thus, the air outlet structure 100 can achieve a variety of air supply effects, such as directional air outlet or sweeping air.

[0057] Of course, when the airflow velocities of the first air duct 11 and the second air duct 12 are changed, if the airflow velocity of the first air supply airflow 10a delivered by the first air outlet 13 is greater than the airflow velocity of the second air supply airflow 10b delivered by the second air outlet 14, the air supply direction of the actual air supply airflow 10c is deflected toward the air supply direction close to the second air supply airflow 10b; if the airflow velocity of the second air supply airflow 10b delivered by the second air outlet 14 is greater than the airflow velocity of the first air supply airflow 10a delivered by the first air outlet 13, the air supply direction of the actual air supply airflow 10c is deflected toward the air supply direction close to the first air supply airflow 10a; of course, the airflow velocity of the first air supply airflow 10a can also be equal to the airflow velocity of the second air supply airflow 10b. In this way, the air supply direction of the actual air supply airflow 10c is adjusted.

[0058] For example, when the first air outlet 13 and the second air outlet 14 supply air together, Figure 3 and Figure 6 As shown, the first supply air flow 10a and the second supply air flow 10b merge into the actual supply air flow 10c, and the air supply direction of the actual supply air flow 10c is basically located between the angle area formed by the air supply direction of the first supply air flow 10a and the air supply direction of the second supply air flow 10b. When the air flow velocity of the first supply air flow 10a remains unchanged, the air flow velocity in the second air duct 12 can be increased to increase the air flow delivery degree of the second supply air flow 10b, so that the air supply direction of the actual supply air flow 10c is deflected toward the air supply direction of the second supply air flow 10b, or, when the air flow velocity of the second supply air flow 10b remains unchanged, the air flow velocity in the first air duct 11 can be reduced to reduce the air flow delivery degree of the first supply air flow 10a, so that the air supply direction of the actual supply air flow 10c is deflected toward the air supply direction of the second supply air flow 10b, thereby realizing the deflection of the actual supply air flow 10c toward the air supply direction of the second supply air flow 10b; when the air flow velocity of the second supply air flow 10b remains unchanged When the air flow velocity in the first air duct 11 is increased, the air flow velocity of the first supply air flow 10a is increased, so that the air supply direction of the actual supply air flow 10c is deflected toward the air supply direction of the first supply air flow 10a. Alternatively, when the air flow velocity of the first supply air flow 10a remains unchanged, the air flow velocity in the second air duct 12 can be reduced to reduce the air flow rate of the second supply air flow 10b, so that the air supply direction of the actual supply air flow 10c is deflected toward the air supply direction of the first supply air flow 10a. Thus, the actual supply air flow 10c is deflected toward the air supply direction of the first supply air flow 10a, and the air supply direction of the actual supply air flow 10c is adjusted, so that air supply effects such as directional air supply or sweeping air can be achieved.

[0059] Compared with some technologies, the air outlet structure needs an air guide plate or a switch door to control the direction of the air supply airflow to achieve the corresponding air supply effect. In the present application, the air outlet directions of the first air outlet 13 and the second air outlet 14 are set to be different, so that the air supply airflow blown out of the first air outlet 13 and the air supply airflow blown out of the second air outlet 14 intersect, and the first air supply airflow 10a of the first air outlet 13 and the second air supply airflow 10b of the second air outlet 14 merge into the actual air supply airflow 10c. The airflow speed of the first air duct 11 or the second air duct 12 can be adjusted to change the airflow speed of the first air supply airflow 10a of the first air outlet 13 or the airflow speed of the second air supply airflow 10b of the second air outlet 14 to achieve the airflow direction of the actual air supply airflow 10c, thereby achieving air supply effects such as directional air supply or sweeping air, and structures such as switch doors or air guide plates for adjusting the air supply direction can be eliminated, which can reduce costs, save assembly processes of the air outlet structure and the above-mentioned structure for adjusting the air supply direction, and achieve differentiated design.

[0060] It should be noted that the air outlet direction of the first air outlet 13 can be determined by the opening direction of the first air outlet 13 and the extension direction of the partial air duct wall of the first air duct 11 extending to the first air outlet 13, and the air outlet direction of the second air outlet 14 can be determined by the opening direction of the second air outlet 14 and the extension direction of the partial air duct wall of the second air duct 12 extending to the second air outlet 14; that is, the air outlet direction of the first air outlet 13 and the air outlet direction of the second air outlet 14 are determined by the structure of the shell 1 itself.

[0061] According to the air outlet structure 100 of the embodiment of the present invention, the air outlet directions of the first air outlet 13 and the second air outlet 14 are different, so that the air supply airflows blown out of the first air outlet 13 and the second air outlet 14 intersect. As a result, the air supply airflow of the first air outlet 13 and the air supply airflow of the second air outlet 14 merge to form a mixed air supply airflow, and the airflow direction of the mixed air supply airflow can be changed by adjusting the wind speed ratio and / or air volume ratio of the air supply airflow of the first air outlet 13 and the air supply airflow of the second air outlet 14, and then the air supply direction of the mixed air supply airflow can be adjusted, so that directional air supply and sweeping air supply effects can be achieved, without the need to set up an air guide plate or a switch door for adjusting the air supply direction, which is conducive to simplifying the structure, reducing costs, and saving assembly processes.

[0062] It can be understood that the air outlet structure 100 of the embodiment of the present application can be used in an air conditioner 200, a purifier, a humidifier, etc.

[0063] In some embodiments, Figure 2-Figure 3As shown, the first air duct 11 and the second air duct 12 have a common air duct wall 1a, which is conducive to simplifying the air duct structure in the shell 1 and reducing the amount of material used; the first air duct 11 also has a first air duct wall 11a, and the first air duct wall 11a and the common air duct wall 1a define a first air outlet 13, and the second air duct 12 also has a second air duct wall 12a, and the second air duct wall 12a and the common air duct wall 1a define a second air outlet 14, thereby facilitating the first air outlet 13 and the second air outlet 14 to be arranged adjacent to each other, and the first air outlet 13 and the second air outlet 14 can be in a relatively close position, so that the first supply air flow 10a and the second supply air flow 10b can be merged into a mixed supply air flow, which is conducive to improving the airflow mixing effect, and at the same time is conducive to reducing the distance between the mixing area of ​​the first supply air flow 10a and the second supply air flow 10b and the shell 1, so that the flow rate of the first supply air flow 10a and the second supply air flow 10b at the mixing area can be appropriately increased, so as to further improve the airflow mixing effect and improve the feasibility of wind control.

[0064] Of course, in other embodiments of the present application, the first air duct 11 and the second air duct 12 may not have a common air duct wall 1a.

[0065] In some embodiments, Figure 3 As shown, the first air duct wall 11a is arranged on the thickness side of the common air duct wall 1a, so that the wall surface on the thickness side of the common air duct wall 1a participates in defining the first air outlet 13, and at least part of the air outlet 13 can be blown roughly along the wall surface on the thickness side of the common air duct wall 1a, and at least part of the second air duct wall 12a extends to be spaced from the end face of the common air duct wall 1a, so that the end face of the common air duct wall 1a participates in defining the second air outlet 14, and at least part of the air outlet 14 can be blown roughly along the end face of the common air duct wall 1a. As a result, it is beneficial to increase the angle between the air outlet direction of the first air outlet 13 and the air outlet direction of the second air outlet 14, thereby helping to expand the adjustable range of the air supply direction of the actual air supply airflow 10c, and helping to increase the sweeping range of the actual air supply airflow 10c.

[0066] The end surface of the common air duct wall 1a can be understood as the end surface of the common air duct wall 1a connecting the wall surfaces on both sides of the thickness thereof.

[0067] In some embodiments, Figure 3 and Figure 5As shown, the above-mentioned at least part of the second air duct wall 12a extends toward the first air duct wall 11a, so that the second air outlet 14 can be set toward the first air outlet 13, which is beneficial to further increase the angle between the air outlet direction of the first air outlet 13 and the air outlet direction of the second air outlet 14. For example, the air outlet direction of the first air outlet 13 and the air outlet direction of the second air outlet 14 can be roughly at an acute angle, a right angle, or an obtuse angle, so as to further expand the adjustable range of the air supply direction of the actual air supply airflow 10c.

[0068] For example, in Figure 3 and Figure 5 In the example, a portion of the second air duct wall 12a extends toward the first air duct wall 11a, and the portion of the second air duct wall 12a and the end face of the common air duct wall 1a define a second air outlet 14, and the second air outlet 14 is generally toward the front side, and the first air duct wall 11a is arranged on the thickness side of the common air duct wall 1a away from the second air duct wall 12a, and the wall surface of the first air duct wall 11a and the thickness side of the common air duct wall 1a defines a first air outlet 13, then the direction of the first air outlet 13 intersects with the direction of the second air outlet 14, so that the first supply air flow 10a intersects with the second supply air flow 10b and merges into an actual supply air flow 10c.

[0069] For example, in Figure 3 , Figure 6 and Figure 7 In the example, the two first air outlets 13 are respectively located on the left and right sides of the air outlet structure 100, and the two second air outlets 14 are respectively located on the left and right sides of the air outlet structure 100, and each second air outlet 14 is respectively extended from the back to the front toward the direction close to another second air outlet 14, and the second air outlet 14 is located on the rear side of the corresponding first air outlet 13, the first air outlet 13 located on the left side generally supplies air toward the left side, and the first air outlet 13 located on the right side generally supplies air toward the right side, then the first supply air airflow 10a and the second supply air airflow 10b intersect and merge into the actual supply air airflow 10c. Since each second air outlet 14 is respectively extended from the back to the front toward the direction close to another second air outlet 14, it is convenient to make the actual supply air airflow 10c on the left and right sides supply air toward the middle area.

[0070] Of course, in other embodiments of the present application, the above-mentioned at least part of the second air duct wall 12a can also extend in a direction away from the first air duct wall 11a, etc.; combined with the figure, the above-mentioned at least part of the second air duct wall 12a can extend from back to front in a direction away from the first air duct wall 11a, or the above-mentioned at least part of the second air duct wall 12a can extend in a straight line from back to front.

[0071] In some embodiments, Figure 3 and Figure 5As shown, the air outlet structure 100 also includes a guide member 2, which is arranged on the other side wall of the thickness of the common air duct wall 1a, and the guide member 2 and the second air duct wall 12a define a second tapered section 12b, then the guide member 2 is arranged in the second air duct 12, and the second tapered section 12b is located in the second air duct 12; in the flow direction of the air flow in the second air duct 12, the cross-sectional area of ​​the second tapered section 12b decreases, then the air flow area of ​​the second tapered section 12b decreases along the air flow direction of the second air duct 12, and the second tapered section 12b has an air flow acceleration effect, so that the air flow in the second air duct 12 increases the air flow speed through the second tapered section 12b, thereby increasing the air flow speed of the second supply air flow 10b sent out from the second air outlet 14, which is beneficial to the adjustment of the air flow direction of the actual supply air flow 10c, and at the same time is beneficial to reducing the requirements for the air supply capacity of the fan component 102 connected to the second air duct 12.

[0072] Optionally, the air guide 2 and the common air duct wall 1a may be an integral part or a separate part. For example, the air guide 2 and the common air duct wall 1a are integrally formed.

[0073] Optionally, at least part of the second tapered section 12b is configured as a preset section, the width of the upstream end of the preset section in the cross section is L2, the width of the downstream end of the preset section in the cross section is L1, L2>L1, 6mm≤L1≤15mm. For example, L1 can be 6mm, 9mm, 10mm, 12mm, or 15mm, etc.

[0074] Optionally, the guide member 2 includes a first guide portion and a second guide portion which are connected by a bend. In the airflow direction of the second air duct 12, the first guide portion is upstream of the second guide portion. The first guide portion and the second air duct wall 12a define a second tapered section 12b. The guide surface of the second guide portion is flush with the end surface of the common air duct wall 1a so as to increase the guide area at the end surface of the common air duct wall 1a, and the second guide portion is connected to the common air duct wall 1a.

[0075] It is worth noting that, in the flow direction of the airflow in the second air duct 12, the second tapered section 12b can be located in the upstream section, middle section, or downstream section of the second air duct 12; to simplify the description, the following text only takes the example that the second tapered section 12b can be located in the downstream section of the second air duct 12 for explanation.

[0076] In some embodiments, the first air duct 11 and the second air duct 12 correspond to different fan components 102, respectively. The fan component 102 of the first air duct 11 is a cross-flow fan, and the fan component 102 of the second air duct 12 is a centrifugal fan. Under the same working conditions (power, etc.), due to the use restrictions of the centrifugal fan, the performance of the cross-flow fan is stronger than that of the centrifugal fan, that is, the air volume or air flow velocity formed by the cross-flow fan in the first air duct 11 is greater than the air volume or air flow velocity formed by the centrifugal fan in the second air duct 12. Therefore, by providing a second tapered section 12b in the second air duct 12, the air flow in the second air duct 12 is accelerated, so that the air flow velocity of the second air supply airflow 10b can be increased, so that the second air supply airflow 10b can be better matched with the first air supply airflow 10a. The implementation scheme in which the fan component 102 of the first air duct 11 is a cross-flow fan and the fan component 102 of the second air duct 12 is a centrifugal fan will be described in detail below and will not be repeated here.

[0077] In some embodiments, Figure 3 and Figure 5 As shown, the first air duct 11 includes a first tapered section. In the flow direction of the air flow in the first air duct 11, the cross-sectional area of ​​the first tapered section decreases. The first tapered section is arranged adjacent to the first air outlet 13 or is arranged at the first air outlet 13. Then, the first tapered section has an airflow acceleration effect, which can increase the airflow velocity of the first air supply airflow 10a sent out from the first air outlet 13, which is beneficial to the adjustment of the airflow direction of the actual air supply airflow 10c, and at the same time is beneficial to reducing the requirements for the air supply capacity of the fan component 102 connected to the first air duct 11; and / or, the second The air duct 12 includes a second tapered section 12b. In the flow direction of the air flow in the second air duct 12, the cross-sectional area of ​​the second tapered section 12b decreases. The second tapered section 12b is arranged adjacent to the second air outlet 14 or is arranged at the second air outlet 14. The second tapered section 12b has an airflow acceleration effect, which can increase the airflow velocity of the second supply air flow 10b sent out from the second air outlet 14, which is beneficial to the adjustment of the airflow direction of the actual supply air flow 10c, and at the same time is beneficial to reducing the requirements for the air supply capacity of the fan component 102 connected to the second air duct 12.

[0078] Optionally, when the first tapered section is arranged adjacent to the first air outlet 13, the portion of the first air duct 11 located downstream of the first tapered section can be constructed as an air duct section with a constant cross-sectional area; when the second tapered section 12b is arranged adjacent to the second air outlet 14, the portion of the second air duct 12 located downstream of the second tapered section 12b can be constructed as an air duct section with a constant cross-sectional area.

[0079] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0080] In some embodiments, Figure 1-Figure 3 As shown, the air outlet structure 100 also includes at least one first air guide blade 3, which is arranged at the first air outlet 13, and the first air guide blade 3 extends along the length direction of the first air outlet 13, so that the first air guide blade 3 can guide the supply air flow of the first air outlet 13 (i.e., the first supply air flow 10a), which can improve the stability of the first supply air flow 10a, and is beneficial to the first supply air flow 10a and the second supply air flow 10b to merge, so as to participate in the adjustment of the airflow direction of the actual supply air flow 10c. At the same time, the first air guide blade 3 can have a certain strengthening effect on the shell 1, which is beneficial to improving the structural stability of the air outlet structure 100.

[0081] Optionally, the first air guide blade 3 and the housing 1 are an integral part or a separate part. For example, the first air guide blade 3 is integrally formed with the housing 1, or the first air guide blade 3 is assembled with the housing 1.

[0082] In some embodiments, Figure 1-Figure 3 There are multiple first air guide blades 3, each of which is formed as a curved plate (for example, the first air guide blade 3 is an arc-shaped plate), and each of the first air guide blades 3 extends in the flow direction of the airflow in the first air duct 11 in a direction away from the corresponding second air outlet 14. The first air guide blades 3 can guide the first supply air flow 10a to be sent out in a direction deviating from the second air outlet 14.

[0083] For example, in Figure 2 In the example, the second air outlet 14 discharges air roughly toward the front, the first air outlet 13 extends in the vertical direction, a plurality of first air guide blades 3 are arranged at intervals at the first air outlet 13 along the width direction of the first air outlet 13, and each first air guide blade 3 bends and extends in a direction away from the second air outlet 14 to guide the first supply air flow 10a so that the supply direction of the first supply air flow 10a is deflected toward the front.

[0084] Optionally, the air outlet structure 100 further includes a plurality of reinforcing ribs 6, which are disposed at the first air outlet 13, and the plurality of reinforcing ribs 6 are disposed along the length direction of the first air outlet 13 (eg Figure 7The plurality of reinforcing ribs 6 and the plurality of first air guide blades 3 are arranged at intervals (in the vertical direction) so that the plurality of reinforcing ribs 6 and the plurality of first air guide blades 3 form a mesh structure, thereby improving the overall structural strength of the plurality of first air guide blades 3 and improving the stability of guiding the first air supply airflow 10a. Optionally, the extending direction of the reinforcing ribs 6 intersects or is perpendicular to the extending direction of the first air guide blades 3.

[0085] It can be understood that multiple reinforcing ribs 6 and multiple first air guide blades 3 are arranged at the first air outlet 13, which can realize the function of a protective net or grille, so that when the air outlet structure 100 is used in the air conditioner 200, there is no need to set up a protective net or grille separately, thereby eliminating the design of the protective net or grille, which is beneficial to reducing the production cost of the air conditioner 200.

[0086] In some embodiments, Figure 3 , Figure 8 and Fig.10 As shown, the air inlet of the second air duct 12 is arranged in the length direction of the second air duct 12 at the second air outlet 14 (for example Figure 7 The air outlet structure 100 further comprises a plurality of second air guide blades 4, the plurality of second air guide blades 4 are spaced apart along the length direction of the second air outlet 14 and the plurality of second air guide blades 4 are all arranged adjacent to the second air outlet 14, in the flow direction of the airflow in the second air duct 12, the upstream end of each second air guide blade 4 is arranged adjacent to the air inlet of the second air duct 12 in the length direction of the second air outlet 14 relative to the downstream end, that is, each second air guide blade 4 is arranged obliquely, and the upstream end of each second air guide blade 4 is deflected relative to the downstream end toward the direction close to the air inlet of the second air duct 12, so that in the length direction of the second air outlet 14, the upstream end of the second air guide blade 4 is inclined. The distance between the upstream end and the air inlet of the second air duct 12 is smaller than the distance between the downstream end of the second air guide blade 4 and the air inlet of the second air duct 12; and among the two adjacent second air guide blades 4, the upstream end of one away from the air inlet of the second air duct 12 protrudes beyond the upstream end of the other in the direction opposite to the airflow flowing through the second air guide blades 4 (the direction of the airflow flowing through the second air guide blades 4 can be understood as the air guiding direction of the second air guide blades 4), that is, taking the length direction of the second air outlet 14 as the projection direction, among the two adjacent second air guide blades 4, the orthographic projection of the upstream end of one second air guide blade 4 away from the air inlet of the second air duct 12 protrudes beyond the orthographic projection of the upstream end of the other second air guide blade 4.

[0087] Thus, each second air guide blade 44 is arranged at an angle, so that each second air guide blade 4 can better guide the airflow and transport it toward the second air outlet 14; in addition, in the length direction of the second air outlet 14, the plurality of second air guide blades 4 are arranged in sequence along the direction away from the air inlet of the second air duct 12, and along the direction away from the air inlet of the second air duct 12, the plurality of second air guide blades 4 are respectively the first, the second...the nth, and in the direction away from the air inlet of the second air duct 12, among two adjacent second air guide blades 4, the upstream end of one second air guide blade 4 away from the air inlet of the second air duct 12 protrudes compared to the upstream end of the other second air guide blade 4, then in the direction of the airflow flowing in from the air inlet of the second air duct 12, the A second air guide blade 4 blocks the airflow corresponding to its own shielding area and guides it toward the second air outlet 14. The upstream end of the second second air guide blade 4 protrudes from the upstream end of the first second air guide blade 4 and can block the airflow corresponding to the positive projection area of ​​the part on the cross section and guide the airflow toward the second air outlet 14. Similarly, the part of the nth second air guide blade 4 protruding from the upstream end of the (n-1)th second air guide blade 4 can block the airflow corresponding to the positive projection area of ​​the part on the cross section and guide the airflow toward the second air outlet 14, so that the amount of air blocked and guided by each second air guide blade 4 is approximately equal, so that the second air supply airflow 10b of the second air outlet 14 is equal in the length direction (for example Figure 7 This can prevent the air flow from the second air outlet 14 from being larger on the side away from the air inlet of the second air duct 12 in the length direction. In particular, it can solve the problem of larger air flow at the top and smaller air flow at the bottom when the second air duct 12 is connected to the centrifugal fan and the centrifugal fan delivers air from bottom to top.

[0088] For example, in Figure 7 and Figure 8In the example, taking the length direction of the second air outlet 14 as the up-down direction, the second air outlet 14 is provided with five second air guide blades 4 as an example, the air inlet of the second air duct 12 is located at the lower side, and the airflow flowing into the second air duct 12 from the air inlet flows from bottom to top. The five second air guide blades 4 are the first, second, third, fourth and fifth from bottom to top, except for the first second air guide blade 4, each of the remaining second air guide blades 4 includes a blocked portion and a protruding portion, the first second air guide blade 4 blocks the airflow corresponding to the positive projection area of ​​the second air guide blade 4 on the cross section, the blocked portion of the second second air guide blade 4 is blocked by the first second air guide blade 4, and the second second air guide blade 4 The protrusion protrudes from the first air guide blade 4, and the protrusion of the second air guide blade 4 can block the airflow corresponding to the orthographic projection area of ​​the protrusion on the cross section. The blocked portion of the third second air guide blade 4 is blocked by the second second air guide blade 4, and the protrusion of the third second air guide blade 4 protrudes from the second air guide blade 4. Then the protrusion of the third second air guide blade 4 can block the airflow corresponding to the orthographic projection area of ​​the protrusion on the cross section, and so on. Each second air guide blade 4 can block and guide the airflow, and the amount of airflow blocked by each second air guide blade 4 is approximately equal. As a result, the second supply air flow 10b of the second air outlet 14 is more uniform in the up and down directions.

[0089] Optionally, the downstream ends of multiple second air guide blades 4 are located on the same longitudinal section to ensure that the downstream ends of the multiple second air guide blades 4 are aligned in the direction of the airflow flowing through the second air guide blades 4. At this time, the width of the multiple second air guide blades 4 in the direction of the airflow flowing through them can be changed to achieve the upstream end of one of the two adjacent second air guide blades 4 away from the air inlet of the second air duct 12 protruding from the upstream end of the other in the direction opposite to the airflow flowing through the second air guide blades 4. At this time, the width of one of the two adjacent second air guide blades 4 away from the air inlet of the second air duct 12 in the direction of the airflow flowing through this second air guide blade 4 is greater than the width of the other in the direction of the airflow flowing through the other, which is convenient for simplifying the setting of the air outlet structure 100.

[0090] For example, in Figure 1 , Figure 3 and Fig.10 In the example, the second air duct 12 extends in the vertical direction, the air inlet of the second air duct 12 is located at the lower side of the second air duct 12, the air flow direction of the second air duct 12 is transported toward the upper side, and the air flow direction of the second air outlet 14 is transported approximately horizontally (for example Figure 3The second air outlet 14 in the middle supplies air roughly toward the front side), a plurality of second air guide blades 4 are arranged at vertical intervals, the downstream end of each second air guide blade 4 is located in the same longitudinal section (vertical plane), and the upstream end of each second air guide blade 4 is lower than the downstream end, that is, each second air guide blade 4 is in an inclined state with the upstream end facing downward and the downstream end facing upward, and on the horizontal projection plane, the projections of the downstream sections of two adjacent second air guide blades 4 overlap, and of the two adjacent second air guide blades 4, the projection of the upstream end of the second air guide blade 4 on the upper side protrudes from the projection of the upstream end of the second air guide blade 4 on the lower side in the direction opposite to the airflow flowing through the second air guide blade 4.

[0091] Optionally, the downstream ends of the plurality of second air guide blades 4 are fixedly mounted on the wall surface of the second air duct 12 to ensure that the second air guide blades 4 are reliably disposed so that the second air guide blades 4 can stably guide the airflow in the second air duct 12 .

[0092] Alternatively, if Fig. 9 As shown, the downstream end edge of each second air guide blade 4 is horizontally arranged, and the downstream end edge of each second air guide blade 4 is bent and deformed to adapt to the shape of the second air guide blade 4, so that the downstream end portion of each second air guide blade 4 is parallel to the cross section, so that the appearance of the plurality of second air guide blades 4 at the second air outlet 14 is more neat and beautiful. Of course, the downstream end edge of the second air guide blade 4 can also be inclined relative to the horizontal direction.

[0093] Likewise, in some examples, the upstream end edges of the second air guide blades 4 are all arranged horizontally, and / or the upstream end edges of the second air guide blades 4 are arranged inclined relative to the horizontal direction.

[0094] In some embodiments, Fig.10 As shown, in the longitudinal section, the angle between the second air guide blade 4 and the cross section is α, 10°≤α≤80°, the longitudinal section is parallel to the length direction of the second air outlet 14, and the cross section is perpendicular to the length direction of the second air outlet 14, so that the second air guide blade 4 can better guide the airflow in the second air duct 12 toward the second air outlet 14, which is beneficial to make the air flow of the second air outlet 14 in the length direction more uniform.

[0095] It should be noted that, in the longitudinal section, the angle between the second air guide blade 4 and the cross section can be understood as the angle α between the straight line where the longitudinal section and the second air guide blade 4 intersect the cross section, or the angle α between the tangent at any point on the curve where the longitudinal section and the second air guide blade 4 intersect the cross section; in addition, there are countless longitudinal sections parallel to the length direction of the second air outlet 14, and in any longitudinal section, the angle α between the second air guide blade 4 and the cross section satisfies 10°≤α≤80°.

[0096] Preferably, in the longitudinal section where the flow direction of the airflow in the second air duct 12 before the second air guide blade 4 and the flow direction of the airflow guided by the second air guide blade 4 are located, the angle between the second air guide blade 4 and the cross section is α, 10°≤α≤80°. In conjunction with the figure, the length direction of the second air outlet 14 is the up-down direction, the air inlet of the second air duct 12 is located at the lower side of the second air duct 12, the flow direction of the airflow in the second air duct 12 before the second air guide blade 4 is from bottom to top, and the flow direction of the airflow guided by the second air guide blade 4 is horizontally inclined upward.

[0097] Optionally, in the longitudinal section, the angle α between the second air guide blade 4 and the cross section may be 10°, 20°, 23°, 30°, 40°, 65°, or 80°, etc. It is understandable that in the longitudinal section, the angles between the second air guide blades 4 and the cross section may be equal or different.

[0098] In some embodiments, in combination Fig.10 As shown, in the cross section, the distance between the positive projections of the upstream ends of two adjacent second air guide blades 4 is x, 3mm≤x≤8mm, and the cross section is perpendicular to the length direction of the second air outlet 14, so that there is sufficient spacing between the upstream ends of two adjacent second air guide blades 4 in the vertical direction to ensure that each second air guide blade 4 can block the airflow in a suitable area, so as to ensure that the airflow guided by each second air guide blade 4 is approximately equal, so that the distribution of the supply airflow of the second air outlet 14 in the length direction is more uniform.

[0099] For example, combined with Fig.10 , the second air duct 12 extends in the vertical direction, a plurality of second air guide blades 4 are arranged in the second air duct 12 at intervals in the vertical direction, and the width of the orthographic projections of the plurality of second air guide blades 4 on the cross section in the direction of the air flow passing through the second air guide blades 4 increases from bottom to top, the downstream ends of the plurality of second air guide blades 4 are all in the same vertical plane, and in the cross section, the distance between the orthographic projections of the upstream ends of two adjacent second air guide blades 4 is x, and the plurality of second air guide blades 4 are the first, the second, ... the nth from bottom to top, and when the second air duct 12 extends in the vertical direction, the width of the orthographic projections of the plurality of second air guide blades 4 on the cross section in the direction of the air flow passing through the second air guide blades 4 increases from bottom to top, and the downstream ends of the plurality of second air guide blades 4 are all in the same vertical plane, and the distance between the orthographic projections of the upstream ends of two adjacent second air guide blades 4 is x, and the plurality of second air guide blades 4 are the first, the second, ... the nth from bottom to top, and when the second air When the airflow in the duct 12 flows from bottom to top, the first second air guide blade 4 blocks part of the airflow and guides the airflow toward the second air outlet 14, the second second air guide blade 4 blocks part of the remaining airflow and guides the airflow toward the second air outlet 14, and so on. The nth second air guide blade 4 located on the uppermost side blocks part of the remaining airflow and guides the airflow toward the second air outlet 14, and the amount of airflow blocked and guided by each second air guide blade 4 is approximately equal. Therefore, the air supply airflow of the second air outlet 14 in the length direction is uniform.

[0100] Optionally, in the cross section, the distance x between the orthographic projections of the upstream ends of two adjacent second air guide blades 4 may be 3 mm, 4 mm, 5 mm, 6 mm, 7 mm, or 8 mm, etc. It is understandable that, when there are three or more second air guide blades 4, in the cross section, the distance x between the orthographic projections of the upstream ends of any two adjacent second air guide blades 4 may be equal or unequal.

[0101] Optionally, the distance between two adjacent second air guide blades 4 in the length direction of the second air outlet 14 is y, 25mm≤y≤225mm, to ensure that there is a suitable distance between two adjacent second air guide blades 4 so that the second air guide blades 4 can guide a suitable amount of airflow.

[0102] In some embodiments, Figure 7 As shown, the vertical height range occupied by the first air duct 11 is consistent with the vertical height range occupied by the second air duct 12, the length direction of the first air outlet 13 and the length direction of the second air outlet 14 are both consistent with the vertical direction, and the length of the first air outlet 13 and the length of the second air outlet 14 are consistent, so that the first supply air flow 10a and the second supply air flow 10b are matched in vertical height, so as to improve the uniformity of the air flow velocity and air flow volume of the actual supply air flow 10c in vertical height, which is beneficial to improving user comfort.

[0103] Among them, the air inlet of the first air duct 11 and the air inlet of the second air duct 12 are respectively arranged on different sides of the air outlet structure 100, so as to reasonably set the first air duct 11 and the second air duct 12, so as to fully utilize the internal space of the air outlet structure 100, and facilitate the reasonable arrangement of the fan components 102 respectively connected to the first air duct 11 and the second air duct 12.

[0104] In some embodiments, Figure 3 and Figure 7 As shown, there are two first air outlets 13 and second air outlets 14 respectively, and the two first air outlets 13 are respectively arranged on the left and right sides of the air outlet structure 100, each first air outlet 13 corresponds to a second air outlet 14 and each first air outlet 13 is located at the front side of the corresponding second air outlet 14, and each second air outlet 14 extends from back to front toward the direction close to another second air outlet 14, so that the positions of the first air outlet 13 and the second air outlet 14 are adapted to each other, so that the direction of the first air outlet 13 intersects with the direction of the second air outlet 14, so that the first supply air airflow 10a and the second supply air airflow 10b can be merged into the actual supply airflow 10c.

[0105] For example, combined with Figure 3 and Figure 7, the two first air outlets 13 are respectively arranged on the left and right sides of the air outlet structure 100, and the two second air outlets 14 are respectively arranged on the left and right sides of the air outlet structure 100, each first air outlet 13 corresponds to a second air outlet 14 and is located in front of the corresponding second air outlet 14, the first air outlet 13 on the left side generally supplies air toward the left side, and the first air outlet 13 on the right side generally supplies air toward the right side, and each second air outlet 14 extends from back to front toward the direction close to another second air outlet 14 and supplies air in a direction close to each other, then the direction of the first air outlet 13 intersects with the direction of the second air outlet 14, the supply direction of the actual supply air flow 10c is between the supply direction of the first supply air flow 10a and the supply direction of the second supply air flow 10b, and the actual supply air flow 10c on the left and right sides supplies air toward the middle area.

[0106] For example, combined with Figure 3 and Figure 7 , the two first air outlets 13 are respectively arranged on the left and right sides of the air outlet structure 100, and the two second air outlets 14 are respectively arranged on the left and right sides of the air outlet structure 100, and a plurality of first air guide blades 3 are arranged at the first air outlet 13, each of the first air guide blades 3 is formed as a curved plate and extends in the direction of the airflow in the first air duct 11 in the direction away from the corresponding second air outlet 14, that is, each first air guide blade 3 is bent and extended toward the front side, the first air guide blade 3 at the left first air outlet 13 is bent and extended forward from right to left, and the first air guide blade 3 at the right first air outlet 13 is bent and extended forward from left to right, each first air outlet 13 corresponds to a second air outlet 14 and is located in front of the corresponding second air outlet 14, the first air outlet 13 on the left side roughly supplies air toward the left front side, the first air outlet 13 on the right side roughly supplies air toward the right front side, and the two second air outlets 14 roughly supply air toward the front. When the first air duct 11 and the second air duct 12 discharge air together, the airflow velocity of the first supply air flow 10a remains unchanged, and the airflow velocity of the second air duct 12 is increased, and the airflow velocity of the second supply air flow 10b increases, and the actual supply air flow 10c is deflected toward the air supply direction of the second supply air flow 10b, that is, the actual supply air flow 10c is deflected toward the front side. As the airflow velocity of the second supply air flow 10b increases, the actual supply air flow 10c gradually approaches the middle area, so that the actual supply air flow 10c can be directed closer to the wind in the middle area, which is beneficial to solving the situation where there is almost no wind in the middle area when air is supplied from the left and right.

[0107] In some embodiments, Figure 3As shown, there are two first air outlets 13 and two second air outlets 14, and the two first air outlets 13 are respectively arranged on the left and right sides of the air outlet structure 100, and the first air duct 11 includes a main air duct path 111 and two air duct branches 112, each air duct branch 112 is connected to the main air duct path 111, and the two air duct branches 112 are respectively connected to the two first air outlets 13, so that the main air duct path 111 forms an airflow, and the airflow is distributed from the main air duct path 111 to the two air duct branches 112, and the airflow of each air duct branch 112 is sent out from the corresponding first air outlet 13, so as to increase the air supply range of the air conditioner 200.

[0108] Optionally, a flow divider 5 is provided in the first air duct 11, and the flow divider 5 can distribute the airflow of the main air duct 111 to the two air duct branches 112 to ensure that the air volume in the two air duct branches 112 is approximately equal, and to ensure that the air supply volume of the two first air outlets 13 is approximately equal.
