[0039] Hereinafter, the fresh air component 10 according to an embodiment of the present utility model will be described with reference to the accompanying drawings.

[0040] like Figure 1-Figure 8As shown, the fresh air component 10 according to the embodiment of the utility model comprises: a fresh air module 11 and a pipe joint 12, the fresh air module 11 has a fresh air joint 111, the end of the fresh air joint 111 has a limiting portion 112 and a connecting portion 113, the limiting portion 112 and the connecting portion 113 are arranged at intervals along the circumference of the fresh air joint 111, and the limiting portion 112 is formed with a limiting groove 114 open in the axial direction of the inner cavity 115 of the fresh air joint 111; the end of the pipe joint 12 has a flange portion 121 and a fixing portion 122 arranged at intervals along the circumference, the flange portion 121 is plugged and matched with the limiting groove 114, and the fixing portion 122 is fixedly connected with the connecting portion 113. In this way, the installation difficulty of the fresh air component 10 can be reduced, and the practicality of the fresh air component 10 can be improved.

[0041] For example, refer to Figure 1-Figure 3 As shown, a fresh air component 10 is installed in the air conditioner 100, and the fresh air component 10 includes a fresh air module 11 and a pipe joint 12. The fresh air module 11 has a fresh air joint 111, and the fresh air joint 111 forms an inner cavity 115 connected to the fresh air module 11, and the inner cavity 115 is used to circulate the fresh air flow. The fresh air joint 111 is protruding, and the end of the fresh air joint 111 has a limiting portion 112 and a connecting portion 113, and the limiting portion 112 and the connecting portion 113 are arranged at intervals along the circumference of the fresh air joint 111 of the fresh air joint 111, and a limiting groove 114 is formed at the limiting portion 112, and the limiting groove 114 is opened toward the axial direction of the inner cavity 115.

[0042] The pipe joint 12 is connected to the fresh air duct, and the pipe joint 12 has a flange portion 121 and a fixing portion 122. The flange portion 121 and the fixing portion 122 are arranged at intervals along the circumference of the fresh air joint 111 of the fresh air joint 111. The flange portion 121 is arranged opposite to the limiting groove 114, and the fixing portion 122 is arranged opposite to the connecting portion 113. For example, the flange portion 121 and the fixing portion 122 can be arranged on both sides of the pipe joint 12 along the radial direction of the fresh air joint 111, and the limiting portion 112 and the connecting portion 113 can be arranged on both sides of the fresh air joint 111 along the radial direction of the fresh air joint 111. The flange portion 121 is matched with the limiting groove 114, the flange portion 121 is used to be plugged and matched with the limiting groove 114, and the fixing portion 122 is used to be fixedly connected with the connecting portion 113, so as to connect the fresh air joint 111 with the pipe joint 12, thereby realizing the communication between the pipe joint 12 and the fresh air joint 111.

[0043] Specifically, after the fresh air flow in the fresh air duct flows into the pipe joint 12, the fresh air flow can flow through the pipe joint 12 and the inner cavity 115 of the fresh air joint 111 in sequence to flow into the fresh air module 11, thereby allowing the air conditioner 100 to blow out fresh air.

[0044] According to the fresh air component 10 of the embodiment of the utility model, the flange portion 121 can be inserted into the limiting groove 114, and then the fixing portion 122 and the connecting portion 113 are fixedly connected to achieve the installation of the fresh air connector 111 and the pipe connector 12, which helps to reduce the difficulty of installing the fresh air component 10.

[0045] In some embodiments, the flange portion 121 is sealed with the limiting groove 114. Figure 2 As shown, the size of the flange portion 121 can be set to be the same as the size of the limiting groove 114. When the flange portion 121 is inserted into the limiting groove 114, the side of the flange portion 121 facing the fresh air module 11 can be attached to the inner wall of the limiting groove 114, thereby achieving the seal between the fresh air connector 111 and the pipe connector 12. In this way, the sealing performance of the connection between the fresh air connector 111 and the pipe connector 12 can be improved, the fresh air leakage problem can be improved, and the sealing difficulty of the fresh air component 10 can be reduced. For example, it is only necessary to cover the part of the connection between the fresh air connector 111 and the pipe connector 12 where the limiting groove 114 is not provided with a sealing member, such as a sponge, so that the gap between the fresh air connector 111 and the pipe connector 12 can be fully sealed.

[0046] In some embodiments of the present invention, the limiting portion 112 is disposed at the lower portion of the fresh air connector 111 and the limiting groove 114 is open upward; and / or, the connecting portion 113 is disposed at the upper portion of the fresh air connector 111 .

[0047] For example, refer to Figure 2-Figure 3 As shown, the limiting portion 112 can be arranged at the lower part of the fresh air connector 111, and the limiting groove 114 formed by the limiting portion 112 can be arranged to be open upward. Correspondingly, the flange portion 121 can be arranged at the lower part of the pipe connector 12. The flange portion 121 is suitable for being inserted into the limiting groove 114 from top to bottom to be plugged into and matched with the limiting groove 114, and the assembly process is convenient.

[0048] and / or, refer to Figure 2-Figure 3 As shown, the connecting portion 113 can be arranged on the upper part of the fresh air connector 111, and the fixing portion 122 can be correspondingly arranged on the upper part of the pipe connector 12. When the flange portion 121 is inserted into the limiting groove 114, the operator can operate the fixing portion 122 from above to connect the fixing portion 122 with the connecting portion 113.

[0049] It should be noted that when the limiting portion 112 is disposed at the lower portion of the fresh air connector 111 and the connecting portion 113 is disposed at the upper portion of the fresh air connector 111, the limiting portion 112 and the connecting portion 113 can cooperate with the pipe connector 12 from the upper and lower sides, respectively, which is conducive to improving the cooperation stability between the pipe connector 12 and the fresh air connector 111. In this way, the design rationality of the fresh air component 10 can be improved.

[0050] In some embodiments of the present invention, Figure 3 As shown, the limiting portion 112 is formed as an arc-shaped seat extending along the circumference of the fresh air connector 111, the limiting groove 114 is formed as an arc-shaped groove matching the shape of the arc-shaped seat, and the flange portion 121 is correspondingly configured as an arc-shaped structure corresponding to the arc-shaped groove. In this way, when the flange portion 121 is plugged into the limiting groove 114, the flange portion 121 can fully cooperate with the limiting groove 114 along the circumference.

[0051] Through the above-mentioned arrangement, the limiting portion 112 and the flange portion 121 can have a longer limiting range in the circumferential direction, which is beneficial to improving the matching stability between the pipe joint 12 and the fresh air joint 111, and is beneficial to reducing the positioning difficulty between the limiting portion 112 and the flange portion 121, thereby improving the practicability of the fresh air component 10.

[0052] In some embodiments of the present invention, the central angle α1 of the limiting groove 114 has a value range of 120° to 180°, and / or the depth H of the limiting groove 114 has a value range of 2 mm to 5 mm.

[0053] For example, the value range of the central angle α1 corresponding to the limit groove 114 can be set to 120° to 180°, such as the central angle α1 corresponding to the limit groove 114 can be set to 130°; or, the central angle α1 corresponding to the limit groove 114 can be set to 150°; or, the central angle α1 corresponding to the limit groove 114 can be set to 170°, and this application does not impose any restrictions on this. As a result, the range of the limit fit is relatively large, which is conducive to improving the stability of the limit fit, and when the limit groove 114 and the flange portion 121 are used to achieve local sealing, it is conducive to improving the range of sealing fit and improving the sealing performance.

[0054] And / or, the depth H of the limit groove 114 can be set to a value range of 2 mm to 5 mm, such as the depth H of the limit groove 114 can be set to 2.5 mm; or the depth H of the limit groove 114 can be set to 3.5 mm; or the depth H of the limit groove 114 can be set to 4.5 mm, which is not limited in the present application. This is conducive to improving the reliability of the limit, and can improve the compactness of the structure and reduce the space occupied.

[0055] Through the above arrangement, the supporting effect of the limiting groove 114 on the flange portion 121 can be ensured, and the processing difficulty of the limiting groove 114 can be reduced, thereby improving the design rationality of the fresh air component 10.

[0056] In some embodiments of the present invention, Figure 3As shown, the limiting portion 112 protrudes from the axial end surface 111a of the fresh air connector 111 along the axial direction of the fresh air connector 111. Through the above arrangement, the difficulty of processing the limiting portion 112 can be reduced, and during the installation process, the pipe connector 12 can be attached to the axial end surface 111a of the fresh air connector 111, and then the pipe connector 12 is driven to move relative to the fresh air connector 111, so that the flange portion 121 can be inserted into the limiting groove 114, and the assembly difficulty is relatively low.

[0057] In some embodiments of the utility model, the axial end of the fresh air connector 111 has a flange ring 116 extending radially outward from the fresh air connector 111 and surrounding the inner cavity 115, the end face 116a of the flange ring 116 constitutes the axial end face 111a of the fresh air connector 111, and the limiting portion 112 protrudes from the flange ring 116 along the axial direction of the fresh air connector 111 to define a limiting groove 114 between the flange ring 116 and the limiting portion 112.

[0058] For example, refer to Figure 2-Figure 3 As shown, a flange ring 116 may be provided at the axial end of the fresh air connector 111, the flange ring 116 extends outward along the radial outer side of the fresh air connector 111 and is arranged around the inner cavity 115, the end face 116a of the flange ring 116 facing away from the fresh air module 11 constitutes the axial end face 111a of the fresh air connector 111, and the limiting portion 112 is connected to the flange ring 116 and protrudes from the flange ring 116 along the axial direction of the fresh air connector 111. The limiting portion 112 includes a first sub-portion 1121 and a second sub-portion 1122, the first sub-portion 1121 is arranged parallel to the axial end face 111a, the second sub-portion 1122 is connected between the first sub-portion 1121 and the axial end face 111a, and the first sub-portion 1121, the second sub-portion 1122 and the flange ring 116 jointly define a limiting groove 114.

[0059] It is understandable that, by providing a flange ring 116 at the axial end of the fresh air connector 111 , sufficient processing space can be reserved for the limiting portion 112 , which helps to reduce the difficulty of processing the limiting portion 112 .

[0060] In some embodiments of the utility model, the flange portion 121 is an annular flange 1211 surrounding the pipe joint 12, a portion of the annular flange 1211 is inserted into the limiting groove 114, and the axial end face 1211a of the annular flange 1211 and the end face 116a of the flange ring 116 form a full-circle abutment. Therefore, through the full-circle abutment of the annular flange 1211 and the flange ring 116, the sealing effect of the fresh air joint 111 and the pipe joint 12 can be improved, eliminating the need to use sealing structures such as sponges, reducing costs, and improving assembly efficiency. Of course, if it is necessary to further improve the sealing performance, a sponge ring or the like can also be provided.

[0061] In some embodiments of the present invention, the fixing portion 122 protrudes from the annular flange 1211 along the radial direction of the pipe joint 12. Figure 3 As shown, the flange portion 121 can be constructed as an annular flange 1211 surrounding the pipe joint 12, and the fixing portion 122 can be constructed as a boss shape, so that the fixing portion 122 protrudes from the annular flange 1211 along the radial direction of the pipe joint 12. Through the above arrangement, the processing difficulty of the pipe joint 12 can be reduced, the overall structural strength of the pipe joint 12 is improved, and it can be ensured that the fixing portion 122 is easy to position, thereby improving the design rationality of the fresh air component 10.

[0062] In some embodiments of the present invention, Figure 3-Figure 4 As shown, the limiting portion 112 may be provided with a first positioning portion, and the pipe joint 12 may be provided with a second positioning portion, the first positioning portion and the second positioning portion are arranged opposite to each other, and when the flange portion 121 is inserted into the limiting groove 114, the first positioning portion may be positioned and matched with the second positioning portion along the circumferential direction to limit the relative movement of the pipe joint 12 and the fresh air joint 111 along the circumferential direction of the fresh air joint 111. Thus, the assembly difficulty of the fresh air component 10 may be reduced, and the installation stability of the fresh air joint 111 and the pipe joint 12 may be improved, thereby improving the design rationality of the fresh air component 10.

[0063] In some embodiments of the present invention, Figure 3-Figure 4 As shown, one of the first positioning portion and the second positioning portion is set as a positioning protrusion 123, and the other is set as a positioning groove 117. For example, the first positioning portion can be set as the positioning groove 117, and the second positioning portion can be set as the positioning protrusion 123, and the positioning protrusion 123 is matched with the positioning groove 117. When the flange portion 121 is inserted into the limiting groove 114, the positioning protrusion 123 can be positioned and matched with the positioning groove 117 along the circumference of the fresh air connector 111 of the fresh air connector 111 to limit the relative movement of the pipe joint 12 and the fresh air connector 111 along the circumferential direction. Through the above arrangement, the assembly difficulty of the fresh air component 10 can be reduced, and the assembly stability of the fresh air component 10 can be improved.

[0064] In some embodiments of the utility model, the limiting portion 112 is formed as an arc-shaped seat extending in the circumferential direction, and a positioning groove 117 is provided in the center of the arc length of the limiting portion 112, and a positioning protrusion 123 cooperating with the positioning groove 117 is provided on the pipe joint 12, wherein the positioning groove 117 is formed on a side wall surface of the limiting portion 112 away from the flange ring 116, and the positioning protrusion 123 is arranged on a side of the flange portion 121 away from the fresh air joint 111.

[0065] For example, refer to Figure 3-Figure 4As shown, the limiting portion 112 is formed as an arc-shaped seat extending along the circumference of the fresh air connector 111, so that the limiting portion 112 can define an arc-shaped limiting groove 114. A positioning groove 117 is provided in the center of the arc length of the limiting portion 112, and a positioning protrusion 123 is correspondingly provided on the outer peripheral wall of the pipe connector 12. The positioning protrusion 123 is used to cooperate with the positioning groove 117 to limit the relative movement of the pipe connector 12 and the fresh air connector 111 along the circumferential direction.

[0066] Among them, the positioning groove 117 can be formed on the wall surface of the limiting part 112 away from the flange ring 116, that is, it is set on the first sub-part 1121, and the positioning protrusion 123 is set on the side of the flange part 121 away from the fresh air connector 111. In this way, during the installation process of the fresh air connector 111 and the pipe connector 12, the operator can observe the matching situation of the positioning protrusion 123 and the positioning groove 117 to determine whether the flange part 121 is installed in place. Therefore, it is helpful to reduce the installation difficulty of the fresh air component 10 and improve the design rationality of the fresh air component 10.

[0067] Of course, the present application is not limited thereto, and the positioning groove 117 may also be disposed on the bottom wall of the limiting groove 114 , and the positioning protrusion 123 may be disposed on the outer peripheral wall of the flange portion 121 .

[0068] In some embodiments of the present invention, the connecting portion 113 and the fixing portion 122 are fixedly connected by threaded fasteners. Figure 2-Figure 3 As shown, a threaded hole 1131 may be provided on the connection portion 113, and a through hole 1221 may be correspondingly provided on the fixing portion 122, and a threaded fastener may pass through the through hole 1221 to extend into the threaded hole 1131, thereby being threadedly connected to the connection portion 113. Thus, the fresh air connector 111 and the pipe connector 12 can be easily disassembled and assembled, and are convenient for maintenance, thereby improving the practicality of the fresh air component 10.

[0069] Exemplarily, the threaded fastener extends from the pipe joint 12 in the direction of the fresh air joint 111. For example, a threaded fastener, such as a screw, can be driven in from the pipe joint 12 to the fresh air joint 111, thereby reducing the demand for assembly space. When the installation space is limited, the assembly connection between the pipe joint 12 and the fresh air joint 111 can also be achieved.

[0070] The utility model also provides an air conditioner 100 .

The upper valve can be set at the upper air outlet 60 so that the upper air outlet control component can control the switch of the upper air outlet 60, or the upper valve can be set in the main air duct 70 so that the upper air outlet control component can control the switching of the main air duct 70 and the upper air outlet 60.

[0083] For example, when the air conditioner 100 is in cooling mode, the upper air outlet 60 can be opened (or the main air duct 70 is connected to the upper air outlet 60) by the upper air outlet control component, so that the cold air flow can be blown out from the upper air outlet 60 and the two side air outlets 31, thereby increasing the air outlet range of the cold air flow; or, the upper air outlet 60 can be closed (or the main air duct 70 is disconnected from the upper air outlet 60) by the upper air outlet control component, so that the cold air flow is blown out only from the two side air outlets 31, thereby achieving targeted cooling. In this way, different needs of users can be met.
