[0045] ​The embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and should not be understood as limiting the present application.

[0046] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplicity, the elements and settings of the specific examples in the following description are described in some instances. Of course, they are merely examples and are not intended to limit the present application. In addition, the present application can repeatedly refer to numbers and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides examples of various specific processes and materials, but those skilled in the art can realize the applicability of other processes and / or the use of other materials.

[0047] The air conditioner 100 of the embodiments of the present application is described below with reference to the drawings.

[0048] According to the air conditioner 100 of the embodiments of the present application, as shown in Figure 1 and Figure 2 The air conditioner 100 includes a housing 10 and a fan component 30, the length direction of the housing 10 is the up-down direction, the housing 10 includes a front shell 1 and a back plate 2, the front shell 1 is located in front of the back plate 2, the fan component 30 includes a cross-flow impeller 3 and a cross-flow volute 4, the axis of the cross-flow impeller 3 extends along the up-down direction, the cross-flow volute 4 forms a cross-flow air duct 41 cooperating with the cross-flow impeller 3, and at least part of the cross-flow volute 4 is formed as an integral piece with the back plate 2.

[0049] The housing 10 is the outer frame of the air conditioner 100, the fan component 30 is arranged in the housing 10, and the housing 10 supports and protects the fan component 30; the cross-flow impeller 3 provides flowing air, and the cross-flow volute 4 sends the air generated by the cross-flow impeller 3 along the cross-flow air duct 41.

[0050] In the related art, the cross-flow volute and the back plate are two separate parts, the front shell, the cross-flow volute and the back plate are arranged in sequence in the front-rear direction, and therefore the size of the cross-flow volute and the back plate in the front-rear direction is superimposed, so that the size of the air conditioner in the front-rear direction is large, the floor area is large, and it is not conducive to arrangement.

[0051] In the embodiments of the present application, at least part of the cross-flow volute 4 is formed as an integral piece with the back plate 2, the structure is optimized, the cross-flow volute 4 and the back plate 2 are compact, so that the size of the air conditioner 100 in the front-rear direction can be reduced, the floor area of the air conditioner 100 can be reduced, and the arrangement of the air conditioner 100 is facilitated.

[0052] By forming at least a portion of the cross-flow volute 4 integrally with the back plate 2, the structural strength of the back plate 2 can be improved compared to a back plate with a flat plate portion, thus enhancing the structural stability of the air conditioner 100. Furthermore, by forming at least a portion of the cross-flow volute 4 integrally with the back plate 2, the manufacturing material for this portion of the cross-flow volute 4 can be saved, reducing material usage. It also reduces the mold costs associated with separately molded cross-flow volute 4 and back plate 2, thereby lowering manufacturing costs.

[0053] In addition, at least a portion of the vortex is integrally formed with the back plate 2, which can save the step of assembling the vortex housing 4 with the back plate 2 and improve assembly efficiency.

[0054] According to the embodiment of the present invention, the air conditioner 100, by forming at least a portion of the cross-flow volute 4 with the back plate 2 as a single unit, can reduce assembly steps, improve assembly efficiency, increase production cycle time, and reduce the dimensions of the air conditioner 100 in the front-to-back direction, thereby reducing the floor space occupied by the air conditioner 100 and facilitating its layout. Furthermore, it can enhance the structural strength of the back plate 2, improve the structural stability of the air conditioner 100, reduce material usage, save mold-making costs, and thus lower the manufacturing cost of the air conditioner 100.

[0055] In some embodiments of this utility model, such as Figures 3-5 As shown, the cross-flow volute 4 includes a front volute 42 and a rear volute 43. Both the front volute 42 and the rear volute 43 extend in the vertical direction. The front volute 42 is located in front of the rear volute 43, and the upper end of the front volute 42 is connected to the upper end of the rear volute 43, and the lower end of the front volute 42 is connected to the lower end of the rear volute 43, so as to form a cross-flow air duct 41 between the front volute 42 and the rear volute 43. At least the rear volute 43 is formed as an integral part with the back plate 2.

[0056] Both the front volute 42 and the rear volute 43 extend in the vertical direction. The upper end of the front volute 42 is connected to the upper end of the rear volute 43, and the lower end of the front volute 42 is connected to the lower end of the rear volute 43, so that the cross-flow duct 41 formed between the front volute 42 and the rear volute 43 is only open in the horizontal direction, reducing the airflow leakage loss in the cross-flow duct 41.

[0057] The rear volute 43 is positioned closer to the back plate 2 than the front volute 42. At least the rear volute 43 and the back plate 2 are formed as a single piece, which can improve the structural strength of the back plate 2, reduce the material usage of the rear volute 43, save the mold opening cost of the rear volute 43 separately, and reduce the manufacturing cost.

[0058] In some embodiments of this utility model, the front volute 42, the rear volute 43, and the back plate 2 are all formed as a single piece. This can further improve the structural strength of the back plate 2 and save the mold opening cost of separately molding the cross-flow volute 4; furthermore, the fact that the front volute 42, the rear volute 43, and the back plate 2 are all formed as a single piece can also save the step of assembling the cross-flow volute 4 and the back plate 2 together, reducing assembly difficulty and improving assembly efficiency.

[0059] In some other embodiments of this utility model, the front volute 42 and the rear volute 43 are separate parts that are assembled together.

[0060] The cross-flow volute 4 has only the rear volute 43 and the back plate 2 as a single piece, while the front volute 42 is molded separately and assembled with the rear volute 43. Compared to making the front volute 42, rear volute 43, and back plate 2 all as a single piece, this reduces manufacturing difficulty. Furthermore, the assembly connection between the front volute 42 and the rear volute 43 facilitates the arrangement of the cross-flow impeller 3 within the cross-flow duct 41, reducing the assembly difficulty of the cross-flow impeller 3.

[0061] In some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the air inlet end 421 of the front volute and the air inlet end 431 of the rear volute define the inlet of the cross-flow duct 41, and the air outlet end 432 of the rear volute extends forward relative to the air inlet end 431 of the rear volute. The back plate 2 includes a back plate body 21 and a first support rib 22. The rear volute 43 is connected to the back plate body 21 through the first support rib 22, and the first support rib 22 is disposed near the air inlet end 431 of the rear volute relative to the air outlet end 432 of the rear volute.

[0062] Airflow enters the cross-flow duct 41 through the inlet of the front volute 421 and the rear volute 431, and exits the cross-flow duct 41 through the outlet of the cross-flow duct 41 defined by the outlet of the front volute 42 and the outlet of the rear volute 432. The outlet of the rear volute 432 extends forward relative to the inlet of the rear volute 431 to guide the airflow in the cross-flow duct 41 forward.

[0063] The first support rib 22 connects the back plate body 21 and the rear volute 43. While serving as a connection, the first support rib 22 can also strengthen the structural strength of the end of the rear volute 43. The first support rib 22 can improve the structural stability of the air inlet end 431 of the rear volute, reduce the shaking and noise generated by the air inlet end 431 of the rear volute under the impact of airflow, improve the working stability of the cross-flow volute 4, and reduce the working noise of the fan component 30.

[0064] In some embodiments of this utility model, such as Figure 5 and Figure 6As shown, the back plate 2 also includes a second support rib 23, and the rear volute 43 is also connected to the back plate body 21 through the second support rib 23. The second support rib 23 is set near the air outlet 432 of the rear volute relative to the air inlet end 431 of the rear volute. The part of the back plate body 21 located between the first support rib 22 and the second support rib 23 and opposite to the rear volute 43 is hollowed out.

[0065] The back plate 2 also includes a second support rib 23. The second support rib 23 can not only play a connecting role, but also strengthen the end structure strength of the rear volute 43. The second support rib 23 can improve the structural stability of the air outlet end 432 of the rear volute, reduce the shaking and noise generated by the airflow, improve the working stability of the cross-flow volute 4, and reduce the working noise of the fan component 30.

[0066] like Figure 5 and Figure 6 As shown, the back plate body 21 has a hollow portion 211, which is located between the first support rib 22 and the second support rib 23. The hollow portion 211 is opened opposite to the rear volute 43, and the dimensions of the hollow portion 211 in the vertical direction correspond to the dimensions of the rear volute 43 in the vertical direction.

[0067] The back panel body 21 is connected to the rear volute 43 through the first support rib 22 and the second support rib 23 to improve the structural stability between the rear volute 43 and the back panel 2. Thus, the back panel body 21 can be hollowed out between the first support rib 22 and the second support rib 23 to facilitate the integral molding of the rear volute 43 and the back panel 2. Furthermore, by forming the hollowed-out part 211, the amount of material used can be reduced, thereby reducing the manufacturing cost of the air conditioner 100.

[0068] In some embodiments of this utility model, such as Figure 5 and Figure 7 As shown, the distance between the first support rib 22 and the air inlet end 431 of the rear volute in the left and right direction is the first distance L1, which is less than 0.8 times the radius R of the cross-flow impeller 3.

[0069] When the distance between the first support rib 22 and the air inlet end 431 of the rear volute in the left-right direction is too large, the first support rib 22 cannot effectively strengthen the structural strength of the end of the rear volute 43. Therefore, limiting the distance between the first support rib 22 and the air inlet end 431 of the rear volute in the left-right direction to less than 0.8 times the radius R of the cross-flow impeller 3 can reduce the shaking and noise generated by the air inlet end 431 of the rear volute under airflow impact. Furthermore, when the first distance L1 is small, the volume of the hollow portion 211 on the back panel body 21 will be correspondingly increased, which is beneficial to the integral molding of the rear volute 43 and the back panel 2, and helps to reduce the manufacturing cost of the air conditioner 100.

[0070] In some embodiments of this utility model, such as Figure 2 ,Figure 5 and Figure 6 As shown, the back plate 2 includes a back plate body 21 and a back plate side plate 24. The cross-flow volute 4 includes a rear volute 43, which is located on the front side of the back plate body 21. The back plate side plate 24 is connected to the side of the back plate body 21 away from the rear volute air outlet 432. The back plate side plate 24 gradually extends forward along the direction away from the back plate body 21. An air inlet grille 241 is formed on the back plate side plate 24.

[0071] The air inlet 431 of the rear volute defines the inlet of the cross-flow duct 41. A back panel 24 is provided near the inlet of the cross-flow duct 41, and an air inlet grille 241 is formed on the back panel side panel 24. The air inlet 102 of the air conditioner 100 includes at least a rear air inlet 1023, which is formed at the air inlet grille 241 on the back panel side panel 24. The air inlet grille 241 formed on the back panel side panel 24 facilitates the introduction of external air into the cross-flow duct 41, improving the air intake effect of the air conditioner 100.

[0072] The back panel side plate 24 extends forward gradually in a direction away from the back panel body 21. It is worth noting that the back panel 2 can extend forward along a straight line, a curve, or a broken line, which can be selected according to actual needs, and all are within the protection scope of this utility model.

[0073] It is also worth noting that the air conditioner 100 of this utility model embodiment can be arranged in the corner of the wall, with the back panel 2 set close to the back wall. By setting the back panel side panel 24, the back panel side panel 24 extends forward relative to the back panel body 21, which can increase the gap between the back panel side panel 24 and the wall, which is conducive to airflow and can increase the air intake of the air conditioner 100.

[0074] In some embodiments of this utility model, such as Figure 2 As shown, the back panel side plate 24 has a groove 242, such as Figure 7 As shown, the air conditioner 100 includes a filter element 50 that mates with a slide rail 242, and the filter element 50 blocks the air intake grille 241.

[0075] By setting the filter element 50, the air intake of the air intake grille 241 can be filtered, thereby improving the cleanliness of the intake air, preventing external pollutants from entering the air conditioner 100, and improving the cleanliness of the air output of the air conditioner 100.

[0076] In some embodiments of this utility model, the slide groove 242 is disposed on the back plate side plate 24, such as... Figure 2 As shown, the groove 242 is formed on the air intake grille 241. By integrating the groove 242 into the air intake grille 241, the structural complexity of the air intake grille 241 can be increased, and the structural strength of the back panel side plate 24 at the air intake grille 241 can be strengthened.

[0077] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the end of the back panel side plate 24 away from the back panel body 21 is provided with a reinforcing structure 243.

[0078] It is understandable that setting an air intake grille 241 on the back panel side plate 24 for air intake and opening multiple airflow holes on the back panel side plate 24 would reduce the structural strength of the back panel side plate 24. Therefore, in this embodiment of the utility model, a reinforcing structure 243 is provided at the end of the back panel side plate 24 away from the back panel body 21. The reinforcing structure 243 is provided at the weak end of the back panel side plate 24 to strengthen the structural strength of the back panel side plate 24, which is beneficial to improving the working reliability of the air conditioner 100.

[0079] In some embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the reinforcing structure 243 is formed as a protrusion 2431 that protrudes from back to front, and the protrusion 2431 defines a rearwardly open groove 2432.

[0080] like Figure 5 As shown, the reinforcing structure 243 is formed as an 'n'-shaped protrusion 2431. The protrusion 2431 protrudes from back to front and is a hollow structure, defining a groove 2432 with an opening that faces rearward. By setting the protrusion 2431, the structural complexity of the end of the back panel side plate 24 away from the back panel body 21 can be increased, the structural strength of the back panel side plate 24 can be strengthened, and the hollow design of the protrusion 2431 can also reduce manufacturing costs and contribute to the lightweighting of the air conditioner 100.

[0081] In some embodiments of this utility model, such as Figure 6 and Figure 12 As shown, a plurality of reinforcing ribs 2433 are provided in the groove 2432 at intervals. By providing a plurality of reinforcing ribs 2433 in the groove 243, the structural strength of the reinforcing structure 234 can be improved, and the structural stability of the back plate side plate 24 can be improved.

[0082] In some embodiments of this utility model, such as Figure 1 and Figure 7 As shown, the front shell 1 includes a front panel 11, a first side panel 12 and a second side panel 13. The first side panel 12 and the second side panel 13 extend rearward from both sides of the front panel 11, wherein the second side panel 13 is located on the side of the back panel body 21 away from the back panel side panel 24, and the air outlet 101 of the air conditioner 100 is formed on the front panel 11 and / or the second side panel 13.

[0083] An air inlet grille 241 is formed on the back panel side panel 24, and the air outlet 101 of the air conditioner 100 is formed on the front panel 11 and / or the second side panel 13. The air outlet 101 is far away from the air inlet 102 of the air conditioner 100, which makes it less likely to cause a short circuit problem of return air and improves the air outlet effect of the air conditioner 100.

[0084] Optionally, the air outlet 101 of the air conditioner 100 may be formed separately on the front panel 11; or, alternatively, the air outlet 101 of the air conditioner 100 may be formed separately on the second side panel 13; or, even more alternatively, the air outlet 101 of the air conditioner 100 may be formed on the front panel 11 and the second side panel 13.

[0085] In some embodiments of this utility model, such as Figure 8 and Figure 9 As shown, the intersection of the front panel 11 and the second side panel 13 is the air outlet corner 1a, and the air outlet 101 of the air conditioner 100 is formed at the air outlet corner 1a.

[0086] When the air conditioner 100 is used in a corner, the back panel 2 is positioned close to the rear wall, the first side panel 12 is positioned close to the side wall, and the air outlet corner 1a at the intersection of the front panel 11 and the second side panel 13 is positioned away from the corner. The air outlet 101 formed at the air outlet corner 1a can generate airflow in both the side and front directions. Compared to designs where the air outlet 101 is formed only on the front panel 11 and only on the second side panel 13, the air conditioner 100 of this embodiment has a larger airflow angle, which can improve the airflow effect. Furthermore, the air outlet corner 1a at the intersection of the front panel 11 and the second side panel 13 is the furthest point from the back panel 24, which reduces the likelihood of backflow short-circuiting.

[0087] In some embodiments of this utility model, such as Figures 7-9 As shown, the air inlet 102 of the air conditioner 100 also includes at least one of a side air inlet 1022 and a front air inlet 1021, with the side air inlet 1022 formed on the first side panel 12.

[0100] The back panel 2 is fixedly connected to the front shell 1 through multiple connecting structures 25. The connection between the back panel 2 and the front shell 1 is relatively stable, which can improve the structural stability of the air conditioner 100.

[0101] In some embodiments of this utility model, the left and right sides of the back plate 2 each have a plurality of slots spaced apart in the vertical direction. Correspondingly, the left and right sides of the front shell 1 each have a plurality of buckles spaced apart in the vertical direction. The buckles and slots are arranged in a one-to-one correspondence. After the buckles on the front shell 1 are engaged with the slots on the back plate 2, the back plate 2 and the front shell 1 are then fixedly connected by a plurality of second fasteners.

[0102] In some embodiments of this utility model, such as Figure 2 As shown, an operation hole 26 is also formed on the back panel 2. The air conditioner 100 is the indoor unit of a split air conditioner, and the pipes of the air conditioner 100 are adapted to extend through the operation hole 26 to connect with the outdoor unit of the split air conditioner.

[0103] The front casing 1 of the air conditioner 100 is positioned facing the user, so the operation hole 26 is located on the back panel 2. The pipes of the air conditioner 100 extend through the operation hole 26, which reduces the occupation of external space and reduces obstruction to the user.

[0104] In some embodiments of this utility model, such as Figure 1As shown, the air conditioner 100 also includes a top cover 70 and a chassis 80. The top cover 70 is located at the top of the housing 10, and the chassis 80 is located at the bottom of the housing 10.
