[0045] 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.

[0046] Hereinafter, an air duct member 100 for an air conditioner 1000 according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0047] Reference Figure 1 and Figure 2 As shown, the air duct component 100 for the air conditioner 1000 according to the embodiment of the present invention may include a first component 10 , and the first component 10 includes an air duct housing group 1 , a first air outlet frame 2 , and a second air outlet frame 3 .

[0048] like Figure 1 As shown, the air duct shell group 1 defines a first air supply duct 11 and a second air supply duct 12. The first air supply duct 11 includes an upstream air duct cavity 111 and a downstream air duct cavity 112 arranged above the upstream air duct cavity 111. The air supply of the first air supply duct 11 flows from the upstream air duct cavity 111 to the downstream air duct cavity 112 from bottom to top. The second air supply duct 12 is arranged in the downstream air duct cavity 112. The second air supply duct 12 extends in the front-to-back direction (refer to Figure 2 ), the second air supply duct 12 supplies air in the front-to-back direction. For example, in some embodiments of the present invention, referring to Figure 4 As shown, a centrifugal wind wheel 5 can be provided in the upstream air duct cavity 111 , an axial flow wind wheel 6 can be provided in the second air supply duct 12 , and the air supply direction from the upstream air duct cavity 111 to the downstream air duct cavity 112 is perpendicular to the air supply direction of the second air supply duct 12 .

[0049] like Figure 2 As shown, the first air outlet frame 2 is arranged in front of the air duct shell group 1 and is opposite to the downstream air duct cavity 112, and the second air outlet frame 3 is arranged above the air duct shell group 1. It should be noted that the portion of the second air supply duct 12 that is opposite to the first air outlet frame 2 in the front-to-back direction is the downstream air duct cavity 112, and the portion of the second air supply duct 12 other than the downstream air duct cavity 112 is the upstream air duct cavity 111.

[0050] like Figure 7 As shown, the structure of the air duct component 100 is configured such that part of the air supplied from the downstream air duct cavity 112 flows forward to the first air outlet frame 2, and the other part flows upward to the second air outlet frame 3 (as shown in FIG. Figure 7 The air flow path shown by the single arrow in the middle), the air supply of the second air supply duct 12 all flows from the back to the front to the first air outlet frame 2 (as shown in the figure below). Figure 7 Thus, the airflow in the first air supply duct 11 can flow from the upstream air duct cavity 111 to the downstream air duct cavity 112, a part of the airflow in the downstream air duct cavity 112 flows to the first air outlet frame 2, and another part flows to the second air outlet frame 3, while the airflow in the second air supply duct 12 only flows to the first air outlet frame 2 and does not flow to the second air outlet frame 3.

[0051] Therefore, since in the present application only the first air supply duct 11 provides airflow to the second air outlet frame 3, the second air supply duct 12 does not participate in supplying air to the second air outlet frame 3, thereby avoiding the problem that the second air supply duct 12 interferes with the first air supply duct 11 supplying air to the second air outlet frame 3 and the first air supply duct 11 interferes with the second air supply duct 12 supplying air to the first air outlet frame 2 due to the different air supply directions of the first air supply duct 11 and the second air supply duct 12.

[0052] The air duct housing group 1 is provided with a first air inlet 17 connected with the second air supply duct 12, and an air guide ring 13 is provided at the first air inlet 17. A guide air duct is formed in the air guide ring 13 to guide the airflow at the first air inlet 17 to the second air supply duct 12. Thus, the airflow entering the second air supply duct 12 can be guided by the air guide ring 13, so that the flow of the airflow is more orderly, the smoothness of the flow of the airflow is improved, the air supply noise is reduced, and the air volume is increased.

[0053] According to the air duct component 100 for the air conditioner 1000 according to the embodiment of the present invention, the structure of the air duct component 100 is constructed so that a part of the supply air of the downstream air duct cavity 112 flows forward to the first air outlet frame 2, and the other part flows upward to the second air outlet frame 3, and the supply air of the second air supply duct 12 all flows from back to front to the first air outlet frame 2, and only the first air supply duct 11 provides airflow to the second air outlet frame 3, and the second air supply duct 12 does not participate in supplying air to the second air outlet frame 3, thereby avoiding the problem that the second air supply duct 12 interferes with the air supply of the first air supply duct 11 to the second air outlet frame 3 and the first air supply duct 11 interferes with the air supply of the second air supply duct 12 to the first air outlet frame 2 due to the different air supply directions of the first air supply duct 11 and the second air supply duct 12.

[0054] At the same time, by setting an air guide ring 13 at the first air inlet 17, the air guide ring 13 can guide the airflow entering the second air supply duct 12, making the flow of the airflow more orderly, improving the smoothness of the flow of the airflow, which is beneficial to reducing the air supply noise and increasing the air output.

[0055] In some embodiments of the present invention, the flow area of ​​the air guide ring 13 gradually decreases in the flow direction of the air flow in the second air supply duct 12. Figure 2 As shown, in the flow direction of the airflow in the second air supply duct 12, the air guide ring 13 extends in the direction close to the central axis of the air guide ring 13. It can be understood that by gradually reducing the flow area of ​​the air guide ring 13 in the flow direction of the airflow in the second air supply duct 12, the impact of the airflow on the inner wall of the air guide ring 13 can be reduced, which is conducive to reducing the noise value.

[0056] Optionally, the curved surface formed by the inner wall of the air guide ring 13 is in the shape of a trumpet or a truncated cone, which has a simple structure and is easy to process.

[0057] In some embodiments, in combination Figure 1 , the second air supply duct 12 can be located at the center position in the left-right direction of the downstream air duct cavity 112, a left ventilation channel 14 can be formed between the left side of the second air supply duct 12 and the left wall of the downstream air duct cavity 112, and a right ventilation channel 15 can be formed between the right side of the second air supply duct 12 and the right wall of the downstream air duct cavity 112, and the airflow of the upstream air duct cavity 111 bypasses the second air supply duct 12 from both sides through the left ventilation channel 14 and the right ventilation channel 15 and flows upward to the second air outlet frame 3. In this way, it can be simply and effectively realized that the downstream air duct cavity 112 supplies air to the second air outlet frame 3 without affecting the air outlet of the second air supply duct 12, and the interference of the second air supply duct 12 on the air supply of the downstream air duct cavity 112 to the second air outlet frame 3 can be avoided.

[0058] In some embodiments of the present invention, Figure 1 As shown, the air duct housing group 1 may include a first housing 1b and a second housing 1a connected to each other, and a first air supply duct 11 and a second air supply duct 12 are defined between the first housing 1b and the second housing 1a. That is, the first air supply duct 11 and the second air supply duct 12 may be formed between the first housing 1b and the second housing 1a. Thus, the structure and assembly steps of the air duct housing group 1 may be simplified, which is conducive to improving production efficiency.

[0059] Furthermore, a second air inlet 18 communicating with the upstream air duct cavity 111 of the first air supply duct 11 is formed on the first shell 1b. The first air outlet frame 2 can be integrally formed on the second shell 1a and open forward. Figure 1 As shown, the second air outlet frame 3 may include a rear frame integrally formed on the first housing 1b and a front frame integrally formed on the second housing 1a. When the first housing 1b and the second housing 1a are spliced ​​in place, the rear frame and the front frame are spliced ​​in place to form the second air outlet frame 3. The second air outlet frame 3 is open upward. Thus, the structure of the air duct housing assembly 1 can be further simplified and assembly is convenient.

[0060] In some embodiments of the present invention, the air guide ring 13 is integrally formed with the first housing 1b. The integrally formed structure has high overall strength and stability, and is convenient to form and simple to manufacture.

[0061] According to some embodiments of the present invention, the first housing 1b includes a first bottom plate 150 and two first side plates 151, and the two first side plates 151 are arranged opposite to each other on both sides of the width direction of the first bottom plate 150. A first flange portion 152 is provided at one end of each first side plate 151 away from the first bottom plate 150. The second housing 1a includes a second bottom plate 160 and two second side plates 161, and the two second side plates 161 are arranged opposite to each other on both sides of the width direction of the second bottom plate 160, and a second flange portion 162 corresponding to the first flange portion 152 is provided at one end of each second side plate 161 away from the second bottom plate 160.

[0062] Reference Figure 4 , the two first side panels 151 can be arranged on the left and right sides of the first bottom plate 150 opposite to each other. One end of the first side panel 151 is connected to the first bottom plate 150, and the other end of the first side panel 151 is provided with a first flange portion 152 extending outward. The two first side panels 151 are both substantially perpendicular to the first bottom plate 150 (i.e., the angle between the first side panel 151 and the first bottom plate 150 is 90°, or deviates from 90° in a smaller range, and the specific range of the smaller range can be specifically set according to actual requirements, for example, the angle between the first side panel 151 and the first bottom plate 150 is 60° to 125°). The first flange portion 152 can be formed by folding the other end of the first side panel 151 in a direction away from the central axis of the second air supply duct.

[0063] The two second side panels 161 can be arranged on the left and right sides of the second bottom plate 160 opposite to each other. One end of the second side panel 161 is connected to the second bottom plate 160, and the other end of the second side panel 161 is provided with a second flange portion 162 extending outward, and the second flange portion 162 is connected to the first flange portion 152. The two second side panels 161 are substantially perpendicular to the first bottom plate 150 (that is, the angle between the second side panel 161 and the second bottom plate 160 is 90°, or deviates from 90° in a smaller range, and the specific range of the smaller range can be specifically set according to actual requirements, for example, the angle between the second side panel 161 and the second bottom plate 160 is 60° to 125°). The second flange portion 162 can be formed by folding the other end of the second side panel 161 in a direction away from the central axis of the second air supply duct 12. In this way, the first shell 1b and the second shell 1a can be conveniently spliced ​​into one, which simplifies the assembly steps and improves the assembly efficiency and production efficiency.

[0064] In some specific embodiments of the present invention, the first flange portion 152 and the second flange portion 162 are connected by a fastener. Optionally, the fastener may be a screw, but is not limited thereto. For example, a first screw hole 155 may be provided on the first flange portion 152, and a second screw hole 163 corresponding to the first screw hole 155 may be provided on the second flange portion 162. The fastener passes through the first screw hole 155 and the second screw hole 163 to connect the first flange portion 152 and the second flange portion 162, so that the first shell 1b and the second shell 1a can be conveniently and securely spliced ​​together.

[0065] For example, in some specific embodiments of the present invention, referring to Figure 4 The first flange portion 152 is provided with a screw column 154, a first screw hole 155 is formed in the screw column 154, and a second screw hole 163 is directly penetrated in the second flange portion 162. Thus, the connection reliability of the first flange portion 152 and the second flange portion 162 is improved.

[0066] According to some embodiments of the present invention, a first positioning member 156 is provided on the first flange portion 152, and a second positioning member 164 cooperating with the first positioning member 156 is provided on the second flange portion 162. For example, the first positioning member 156 may be one of a positioning hole and a positioning column, and the second positioning member 164 may be the other of the positioning hole and the positioning column. Thus, the first housing 1b and the second housing 1a can be preliminarily positioned by cooperating with the first positioning member 156 and the second positioning member 164, thereby reducing the difficulty of assembling the first housing 1b and the second housing 1a and improving the assembly efficiency.

[0067] The positioning column may be formed into a double cross rib structure or a triple cross rib structure, which is beneficial to improving the reliability of the fit between the first positioning member 156 and the second positioning member 164 .

[0068] According to some embodiments of the present invention, a baffle 153 extending forward is provided on at least a portion of the outer peripheral wall of the first flange portion 152, or a baffle 153 extending backward is provided on at least a portion of the outer peripheral wall of the second flange portion 162. The baffle 153 can be used to shield the screw column 154 and the positioning column. Specifically, a baffle 153 extending forward is provided on part of the outer peripheral wall of the first flange portion 152, or a baffle 153 extending forward is provided on the outer peripheral wall of the first flange. Alternatively, a baffle 153 extending backward is provided on part of the outer peripheral wall of the second flange portion 162, or a baffle 153 extending backward is provided on the outer peripheral wall of the second flange. As a result, the structures on the first flange portion 152 and the second flange portion 162 can be shielded by the baffle 153, thereby improving the aesthetics of the air duct shell group 1.

[0069] In some embodiments of the present invention, Figure 3 As shown, the air duct component 100 includes an axial flow fan wheel 6, part of which is located in the second air supply duct 12, and the rest of the axial flow fan wheel 6 extends backward from the air guide ring 13. This is conducive to increasing the contact area between the axial flow fan wheel 6 and the air flow, thereby increasing the air supply volume of the second air supply duct 12.

[0070] In some embodiments of the present invention, Figure 3 As shown, in the front-to-back direction, the maximum distance L1 from the portion of the axial flow wind wheel 6 extending backwards from the air guide circle 13 to the air guide circle 13 is 10mm-30mm. In other words, the maximum distance L1 from the portion of the axial flow wind wheel 6 extending backwards from the air guide circle 13 to the air guide circle 13 can take any value between 10mm-30mm. For example, L1 can take values ​​of 10mm, 15mm, 20mm, 25mm, 30mm, etc.

[0071] Therefore, on the one hand, it is helpful to prevent the value of L1 from being too small, and to increase the contact area between the axial flow fan wheel 6 and the airflow, thereby increasing the air supply volume of the second air supply duct 12. On the other hand, it is helpful to prevent the value of L1 from being too large. When the air duct component 100 is installed in the air conditioner 1000, it is helpful to prevent the axial flow fan wheel 6 from interfering with other components in the air conditioner 1000 (such as the evaporator), thereby ensuring the reliability of the operation of the air duct component 100.

[0072] In some embodiments of the present invention, Figure 3As shown, in the radial direction of the axial flow fan wheel 6, the minimum distance L2 from the axial flow fan wheel 6 to the second air supply duct 12 is greater than or equal to 6 mm. For example, the value of L2 can be 6 mm, 6.3 mm, 6.5 mm, 6.8 mm, 7 mm, 7.5 mm, etc. This is conducive to preventing the axial flow fan wheel 6 from interfering with the second air supply duct 12 (for example, the inner wall of the air guide ring 13) during the rotation process, and is conducive to ensuring the reliability of the operation of the air conditioner 1000.

[0073] In some embodiments of the present invention, Figure 4 As shown, the air duct component 100 may include a first air guide component 40, and the first air guide component 40 is arranged in the first air outlet frame 2, that is, at least most of the first air guide component 40 is arranged in the inner cavity of the first air outlet frame 2, and is opposite to the downstream air duct cavity 112 and the second air supply duct 12, the first air guide component 40 includes a first louver 401 and a second louver 402, the first louver 401 extends in the up and down direction, and a plurality of first louvers 401 are spaced apart in the left and right direction, the second louver 402 extends in the left and right direction, and a plurality of second louvers 402 are spaced apart in the up and down direction along the first direction.

[0074] Therefore, the wind sent out from the first air outlet frame 2 by the first air supply duct 11 can be guided by the first louver 401 and the second louver 402, and the wind sent out from the first air outlet frame 2 by the second air supply duct 12 can also be guided by the first louver 401 and the second louver 402, thereby meeting the different actual needs of users.

[0075] In addition, in some examples, such as Figure 7 As shown, the duct component 100 also includes a second component 20 and a driving component 30. The second component 20 defines a third air supply duct 201. The second component 20 is arranged in the second air outlet frame 3, that is, in at least one state, at least most of the second component 20 is arranged in the inner cavity of the second air outlet frame 3, so that the third air supply duct 201 is connected to the inner cavity of the second air outlet frame 313. The driving component 30 is connected to the second component 20 to drive the second component 20 to move relative to the second air outlet frame 313. The driving component 30 is configured to at least drive the second component 20 to move to at least a portion of the outlet 202 of the third air supply duct 201 exposed outside the second air outlet frame 3.

[0076] Therefore, the driving component 30 can be used to drive the second component 20 to move as needed, so that at least part of the outlet 202 of the third air supply duct 201 is exposed outside the second air outlet frame 3, so that the outlet 202 of the third air supply duct 201 is used to supply air outward to meet different air supply requirements.

[0077] For example, when the driving component 30 can drive the second component 20 to rise upward, at least a portion of the outlet 202 of the third air supply duct 201 can be exposed above the second air outlet frame 313. At this time, the overall air outlet height of the air conditioner 1000 can be increased; when the driving component 30 drives the second component 20 to descend downward, at least a portion of the outlet 202 of the third air supply duct 201 can be exposed below the second air outlet frame 313. At this time, the overall air outlet height of the air conditioner 1000 can be lowered; when the driving component 30 can drive the second component 20 to move horizontally, at least a portion of the outlet 202 of the third air supply duct 201 can be exposed on the horizontal side of the second air outlet frame 313. At this time, the overall air outlet angle and range of the air conditioner 1000 in the horizontal direction can be changed.

[0078] For example, in Figure 7 In the specific example shown, the downstream air duct cavity 112 is located above the upstream air duct cavity 111, the second air supply duct 12112 extends in the front-to-back direction, the first air outlet frame 2 is arranged on the front side of the air duct shell group 1, and the second air outlet frame 3 is arranged above the air duct shell group 1. The driving component 30 drives the second component 20 to move up and down relative to the second air outlet frame 3 so that at least part of the outlet 202 of the third air supply duct 201 is exposed above the second air outlet frame 3.

[0079] Therefore, the driving component 30 can be used to drive the lifting and lowering movement of the second component 20 as needed to change the overall air outlet height of the air conditioner 1000, thereby meeting different air outlet requirements. For example, when the air conditioner 1000 is in cooling mode, the second component 20 can be driven to rise so that the outlet 202 of the third air supply duct 201 is exposed upward, thereby increasing the air supply height of the entire air conditioner 1000, thereby extending the air supply distance of the cold air, etc.

[0080] like Figure 6 and Figure 7 As shown, an air conditioner 1000 according to an embodiment of the present invention includes the air duct component 100 according to the above embodiment of the present invention.

[0081] According to the air conditioner 1000 of the embodiment of the present invention, by providing the air duct component 100 of the above embodiment of the present invention, the problem that the second air supply duct 12 interferes with the air supply from the first air supply duct 11 to the second air outlet frame 3, and the problem that the first air supply duct 11 interferes with the air supply from the second air supply duct 12 to the first air outlet frame 2, occurs due to the different air supply directions of the first air supply duct 11 and the second air supply duct 12. At the same time, by providing the air guide ring 13 at the first air inlet 17, the air flow entering the second air supply duct 12 can be guided by the air guide ring 13, so that the flow of the air flow is more orderly, the smoothness of the flow of the air flow is improved, it is beneficial to reduce the air supply noise, and it is beneficial to increase the air output.

[0082] Other structures and operations of the air conditioner 1000 according to the embodiment of the present invention are well known to those skilled in the art and will not be described in detail here.
