[0056] The following is based on the attached Figure 1-Figure 15 A volute assembly 10 for a fresh air module and an air conditioner 100 having the same according to an embodiment of the present invention are described.

[0057] First, after reading this application, those skilled in the art can understand that the first direction, the second direction and the third direction can be in a variety of different orientations, as long as the first direction, the second direction and the third direction are perpendicular to each other. Of course, for the convenience of description, unless otherwise specified, the first direction in this application is the X direction in the figure, that is, the left and right direction of the air conditioner; the second direction is the Y direction in the figure, that is, the front and back direction of the air conditioner; and the third direction is the Z direction in the figure, that is, the up and down direction of the air conditioner.

[0058] Reference Figure 5 and Figure 6As shown, a volute assembly 10 for a fresh air module according to an embodiment of the present invention may include a volute 1 and an air guide duct 2 .

[0059] The volute has an air outlet 103, and the air duct 2 has an air inlet 2a. The air duct 2 and the volute 1 are assembled in a sliding manner so that the air outlet 103 and the air inlet 2a are connected.

[0060] According to the volute assembly 100 of the present invention, when assembling the air duct 2 and the volute 1, the air duct 2 can be inserted into the volute 1, which has high assembly efficiency and is conducive to reducing costs.

[0061] like Figure 7 As shown, the volute 1 has an air outlet 103. For example, a centrifugal wind wheel may be arranged in the volute 1. Figure 5 , Figure 6 and Figure 8 As shown, two limiting portions 11 are provided on the volute 1, and the two limiting portions 11 are located on both sides of the air outlet 103 in the first direction. Each limiting portion 11 extends in a second direction perpendicular to the first direction and includes a first section 111 and a second section 112. One end of the first section 111 is connected to the volute 1 and extends along the third direction toward a direction away from the volute 1, one end of the second section 112 is connected to the other end of the first section 111 and the other end of the second section 112 extends toward another limiting portion 11, and each limiting portion 11 and the surface of the volute 1 jointly define a slide groove 113, and the slide groove 113 has an insertion port 114 at one end along the second direction.

[0062] like Fig. 9 and Fig.10 As shown, both ends of the end surface of the air inlet 2a of the air duct 2 along the first direction are respectively provided with flanges 201 extending outward, each flange 201 extends along the second direction, and the two flanges 201 are inserted into the corresponding two slide grooves 113 through the insertion port 114 to connect the air duct 2 and the volute 1 so that the air outlet 103 and the air inlet 2a are connected. Therefore, when assembling the air duct 2 and the volute 1, the two flanges 201 can be inserted into the corresponding two slide grooves 113 through the insertion port 114 to connect the air duct 2 and the volute 1, which has high assembly efficiency and is conducive to reducing costs.

[0063] Of course, in other embodiments, two limiting portions 11 can be provided on both sides of the air duct 2 in the first direction (i.e., two slide grooves 113 are defined on the air inlet 2a of the air duct 2), and a flange 201 cooperating with the slide groove is provided at the air outlet 103 of the volute 1, and the flange 201 is extended into the slide groove 113, so that the air inlet 2a of the air duct 2 is connected to the air outlet 103 of the volute 1.

[0064] According to the volute assembly 10 for the fresh air module of the embodiment of the present invention, when assembling the air duct 2 and the volute 1, the two flanges 201 can be inserted into the corresponding two slide grooves 113 through the insertion port 114 to connect the air duct 2 and the volute 1, which has high assembly efficiency and is conducive to reducing costs.

[0065] In some embodiments of the present invention, Figure 8 As shown, in the direction of the flange 201 being inserted into the slide slot 113, the two first sections 111 extend toward each other, and the side surfaces of the two flanges 201 that are away from each other extend toward each other. Therefore, in the process of inserting the flange 201 into the slide slot 113, the two flanges 201 and the two first sections 111 are both reduced, which is convenient for installation, and is conducive to accurate positioning, which is conducive to improving the matching accuracy between the two flanges 201 and the two limiting parts 11, thereby improving the matching accuracy between the air duct 2 and the limiting part 11.

[0066] In some optional embodiments of the present invention, Figure 6 and Figure 8 As shown, a stop portion 12 is provided on the volute 1, the stop portion 12 extends in a first direction and the two ends of the stop portion 12 in the first direction are respectively connected to one end of the two limiting portions 11 away from the insertion port 114, and an end of the end face of the air inlet 2a of the air duct 2 along the second direction is provided with an outwardly extending stop section 202, the stop section 202 extends along the first direction and the two ends of the stop section 202 are connected to two flanges 201; when the flange 201 cooperates with the slide groove 113, the stop section 202 abuts against the stop portion 12.

[0067] Furthermore, if Figure 8 As shown, the stopper 12 includes a first stopper section 121 and a second stopper section 122, one end of the first stopper section 121 is connected to the volute 1 and extends along the third direction toward a direction away from the volute 1, one end of the second stopper section 122 is connected to the other end of the first stopper section 121 and the other end of the second stopper section 122 extends toward a direction close to the center line of the air outlet 103 to define a positioning groove connected to the slide groove 113 with the surface of the volute 1, and the stopper section 202 stops in the positioning groove. Thus, the first stopper section 121 can limit the stopper section 202 in the front-to-back direction, and the second stopper section 122 can limit the stopper section 202 in the up-down direction, which is conducive to enhancing the reliability of the cooperation between the air duct 2 and the volute 1.

[0068] Specifically, Figure 5-Figure 8As shown, the volute 1 includes a first volute portion 101 and a second volute portion 102, which are arranged along a first direction and spliced ​​together, a portion of the air outlet 103 is located in the first volute portion 101 and the remaining portion is located in the second volute portion 102, and the stopper 12 includes a first sub-stopper 12a and a second sub-stopper 12b arranged along the first direction, wherein the first sub-stopper 12a is arranged on the first volute portion 101, and the second sub-stopper 12b is located on the second volute portion 102, and an end of the first sub-stopper 12a adjacent to the second sub-stopper 12b is provided with a first reinforcement portion 123 extending in a direction away from the insertion port 114, and an end of the second sub-stopper 12b adjacent to the first sub-stopper 12a is provided with a second reinforcement portion 124 extending in a direction away from the insertion port 114. For example, Figure 1 As shown, the first reinforcement portion 123 and the second reinforcement portion 124 abut against each other in the front-to-back direction.

[0069] Therefore, the provision of the first reinforcement portion 123 and the second reinforcement portion 124 is conducive to enhancing the structural strength of the volute 1 at the air outlet 103 .

[0070] In some embodiments of the present invention, Figure 5 and Fig. 9 As shown, a mounting plate 203 is provided on the end face of the air inlet end of the air duct 2, a first mounting hole 230 is provided on the mounting plate 203, a second mounting hole 13 is provided at a position adjacent to the insertion port 114 of the volute 1, a fastener passes through the first mounting hole 230 and the second mounting hole 13 to connect the volute 1 and the air duct 2, and the volute 1 is connected to the air duct 2 by passing the fastener through the first mounting hole 230 and the second mounting hole 13, which is convenient for assembly and has a high connection strength.

[0071] In some embodiments of the present invention, Figure 5 and Fig. 9 As shown, the second mounting hole 13 is located between the two insertion ports 114. Specifically, the distance between the second mounting hole 13 and the two insertion ports 114 is close. Further, the distance between the second mounting hole 13 and the two insertion ports 114 can be equal, that is, the second mounting hole 13 is located in the middle position of the air outlet 103 along the first direction. As a result, the connection position of the air duct 2 and the volute 1 at this location does not hinder the arrangement of other components, and the mounting plate 203 can better withstand the stress on both sides of the air duct 2 along the first direction, thereby preventing the air duct 2 from deflecting or shaking along the first direction.

[0072] In some embodiments of the present invention, Figure 5 , Figure 9-11As shown, the air duct 2 includes a first shell 21 and a second shell 22, the first shell 21 and the second shell 22 are open on one side facing each other and the first shell 21 and the second shell 22 are spliced ​​together to define an air duct. For example, the first shell 21 and the second shell 22 are spliced ​​along a third direction. The air duct 2 formed by splicing the first shell 21 and the second shell 22 is easy to manufacture and convenient to assemble.

[0073] In some embodiments of the present invention, Figure 9-11 , Fig.14 As shown, a limiting rib 221 is provided on the outer peripheral wall of the second shell 22, and the limiting rib 221 extends in a direction close to the first shell 21 and exceeds the end face of the open end of the second shell 22. The portion of the limiting rib 221 exceeding the open face of the second shell 22 is suitable for abutting against the outer peripheral wall of the first shell 21. The setting of the limiting rib 221 can ensure the assembly accuracy of the first shell 21 and the second shell 22.

[0074] In some embodiments of the present invention, Figure 9-11 , Fig.14 , Fig.15 As shown, there are multiple limiting ribs 221, a portion of the multiple limiting ribs 221 is adjacent to one end of the first shell 21 in the length direction, and the remaining portion of the multiple limiting ribs 221 is arranged adjacent to the other end of the first shell 21 in the length direction. The arrangement of the multiple limiting ribs 221 can provide multiple positioning points for the assembly of the first shell 21 and the second shell 22, and the positioning of the first shell 21 and the second shell 22 is more accurate by respectively contacting the multiple limiting ribs 221 with the outer peripheral walls at different positions of the second shell 22 at different positions.

[0075] In some embodiments of the present invention, Figure 9-13 As shown, a mounting seat 211 is provided on the outer peripheral wall of the first shell 21, and the mounting seat 211 and the limiting rib 221 are arranged opposite to each other in the splicing direction of the first shell 21 and the second shell 22. When the first shell 21 and the second shell 22 are buckled, a first fastening hole 212 is provided on the mounting seat 211, and a second fastening hole 224 corresponding to the first fastening hole 212 is provided on the limiting rib 221. The fastener passes through the first fastening hole 212 and the second fastening hole 224 to connect the mounting seat 211 and the limiting rib 221. The first shell 21 and the second shell 22 are connected by the fastener, and the connection strength is high, which can enhance the reliability of the air duct 2 and is easy to install. Due to this arrangement, it is convenient to extend the fastener into the first fastening hole 212 and the second fastening hole 224. Specifically, the first fastening hole 212 can be a threaded hole. The second fastening hole 224 is a through hole, and the fastener is a threaded connector. The fastener is passed through the second fastening hole 224 and then screwed into the first fastening hole 212 , so as to threadably connect the first shell 21 and the second shell 22 .

[0076] In some examples, such as Fig.14 As shown, a guide surface 204 can be set on the limiting rib 221. In the direction from the second shell 22 to the first shell 21, the guide surface 204 extends obliquely in the direction away from the inside of the air duct 2. The setting of the guide surface 204 can guide the second shell 22, making it easier to splice the second shell 22 to the first shell 21.

[0077] Specifically, Figure 9-11 As shown, the mounting seat 211 can be arranged on both sides of the first shell 21 along the first direction, and the mounting seat 211 arranged there is located at the free end of the first shell 21, that is, the mounting seat 211 is arranged at the edge of the open end of the first shell 21, thereby, most of the side surfaces of the air duct 2 opposite to the second direction can be made smoother, and the mounting seat 211 can also be arranged on the side surface opposite to the open end of the first shell 21. Of course, corresponding positions of the second shell 22 are provided with limiting ribs 221 corresponding to the mounting seat 211 one by one.

[0078] In some embodiments of the present invention, Fig.10 , Fig.11 and Fig.14 As shown, a hook 222 is provided on the inner circumferential wall of the second shell 22, and the hook 222 extends in a direction close to the first shell 21 and exceeds the end face of the open end of the second shell 22. A slot 213 cooperating with the hook 222 is provided on the inner circumferential wall of the first shell 21. The cooperation between the hook 222 and the slot 213 can make the first shell 21 and the second shell 22 connected by snapping, which is convenient for assembly. The hook 222 is provided on the inner circumferential wall of the second shell 22, which can make the outer circumferential surface of the air duct 2 smooth, making it convenient to stick the heat-insulating component on the air duct 2, so that the heat-insulating component and the air duct 2 have a better fit. The snap-on structure does not occupy the space outside the air duct 2, so that other components of the air conditioner 100 can be easily arranged around the air duct 2.

[0079] Specifically, the first shell 21 can be provided with a card slot 213 and a mounting seat 211 at the same time, and the second shell 22 can be provided with a limiting rib 221 with a second fastening hole 224 and a hook 222 at the same time, that is, the first shell 21 and the second shell 22 can be connected by card connection and thread connection, so as to ensure the connection strength between the first shell 21 and the second shell 22, and the threaded connection can limit the first shell 21 and the second shell 22 in multiple directions, and by setting the card connection structure, the setting of the fasteners located on the outer surface of the air duct 2 can be appropriately reduced accordingly, thereby improving the smoothness of the outer surface of the air duct 2.

[0080] In some embodiments of the present invention, Fig.10 , Fig.13 and Fig.14 As shown, a sealing groove 223 extending along the circumferential direction of the second shell 22 is provided on the end face of the open end of the second shell 22, and a sealing protrusion 214 suitable for cooperating with the sealing groove 223 is provided on the end face of the open end of the first shell 21. The cooperation between the sealing groove 223 and the sealing protrusion 214 can enhance the sealing performance of the connection between the first shell 21 and the second shell 22.

[0081] In some examples, the peripheral wall of the sealing groove 223 is located on the outer side of the sealing protrusion 214 (the side away from the air duct 2 ), thereby facilitating the first shell 21 to be buckled onto the second shell 22 from top to bottom.

[0082] like Figure 1 and Figure 2 As shown, the air conditioner 100 according to the embodiment of the present invention comprises: a housing 3 , on which a fresh air outlet 31 is provided; and the volute assembly 10 for the fresh air module mentioned above, which is arranged in the housing 3 .

[0083] According to the air conditioner 100 of the embodiment of the present invention, by setting the above-mentioned volute assembly 10 for the fresh air module, when assembling the air duct 2 and the volute 1, the two flanges 201 can be inserted into the corresponding two slide grooves 113 through the insertion port 114 to connect the air duct 2 and the volute 1, which has high assembly efficiency and is conducive to reducing costs.

[0084] In some embodiments of the present invention, Figure 3 As shown, the inner end surface of the fresh air outlet 31 is provided with limit members 32 on both sides along the third direction, and the air outlet end of the air duct 2 is clamped between the two limit members 32. The two limit members 32 define the installation space of the air duct 2. The air duct 2 is installed in the installation space. The limit members 32 play a role in limiting the position of the air duct 2, so that the air duct 2 is stably installed in the air conditioner 100, thereby improving the reliability of the device.

[0085] In some embodiments of the present invention, Figure 4 As shown, in the direction in which the air duct 2 is inserted into the two limit members 32, the side surfaces of the two limit members 32 facing each other extend toward each other along the assembly direction of the air duct 2, and the two outer side surfaces of the air outlet end of the air duct 2 along the third direction extend toward each other.

[0086] Specifically, the two limit members 32 extend toward each other along the installation direction of the air duct 2, and the distance between the two limit members 32 along the installation direction of the air duct 2 gradually decreases. During assembly, the air duct 2 extends from the end where the distance between the two limit members 32 is larger to between the two limit members 32. Thus, the air duct 2 can be easily extended into the installation space from the end where the distance between the two limit members 32 is larger, which facilitates the assembly of the air duct 2. The air duct 2 has a shape corresponding to the installation space. After the air duct 2 is fully extended into the installation space, the wall surface of the air duct 2 fits with the two limit members 32, so that the limit members 32 can limit the air duct 2.

[0087] In some embodiments of the present invention, the air duct 2 is inserted into the direction of the two limit members 32, and the end face of the air outlet end of the air duct 2 is inclined and extends away from the fresh air outlet 31. The end of the air duct 2 of this shape is easy to extend between the two limit members 32, thereby facilitating the assembly of the air duct 2.
