Needless to say, the purpose of this is to simplify the disclosure, but it is not intended to limit the application in any in any way.

Furthermore, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art can realize the applicability of other processes and / or the use of other materials. ​​​

[0039] Hereinafter, with reference to the drawings, the air conditioner 100 according to the embodiments of the present application is described.

[0040] As shown in the drawings, Figures 1-4 The air conditioner 100 comprises a shell 1, a blowing component 2, a heat exchanger 3 and a heat insulation component 4, the shell 1 has a mounting cavity 10 therein, the shell 1 is formed with an air inlet 11 and an air outlet 12, the blowing component 2 is arranged in the mounting cavity 10 and comprises at least one impeller assembly 20, the impeller assembly 20 comprises a volute 21 and an impeller 22, the volute 21 comprises a first sub-volute 21a and a second sub-volute 21b, the first sub-volute 21a and the second sub-volute 21b are connected by splicing and define an impeller cavity 21c, the impeller 22 is arranged in the impeller cavity 21c, the impeller cavity 21c has an inlet 21d and an outlet 21e, the outlet 21e is communicated with the air outlet 12, the heat exchanger 3 is arranged in the mounting cavity 10 and located between the air inlet 11 and the inlet 21d.

[0041] The first sub-volute 21a and the second sub-volute 21b are connected by splicing to define the impeller cavity 21c, and the impeller 22 is arranged in the impeller cavity 21c, so that the assembly of the impeller assembly 20 is more convenient. For example, the first sub-volute 21a and the second sub-volute 21b can be detachably connected, when the impeller 22 needs to be maintained, the shell 1 can be removed first to expose the impeller assembly 20, then the first sub-volute 21a and the second sub-volute 21b are separated, the impeller 22 can be contacted, and the subsequent maintenance of the impeller 22 by the staff is facilitated, when the maintenance of the impeller 22 is completed, the impeller 22 can be placed in the first sub-volute 21a or the second sub-volute 21b, then the first sub-volute 21a and the second sub-volute 21b are spliced, and finally the shell 1 is reassembled to complete the maintenance of the impeller assembly 20.

[0042] It can be seen that the outlet 21e of the impeller cavity 21c is communicated with the air outlet 12, and the heat exchanger 3 is located between the air inlet 11 and the inlet 21d, so that the external air can flow to the inlet 21d through the air inlet 11 and the heat exchanger 3 in turn, and then flow to the air outlet 12 through the outlet 21e, to complete the refrigeration or heating treatment of the airflow flowing through the air conditioner 100, to meet the refrigeration or heating demand of the user for the air conditioner 100, and the impeller assembly 20 adopts the air suction heat exchange mode for the heat exchanger 3, so that the heat exchange uniformity of the air conditioner 100 is better, and the refrigeration or heating effect of the air conditioner 100 is improved.

[0043] Compared with some technologies, the heat exchanger is located between the air outlet and the outlet, and the fan wheel assembly adopts a blowing heat exchange mode for the heat exchanger. The airflow blown by the fan wheel assembly is relatively concentrated, so that the heat exchange uniformity of the air conditioner is poor, and the refrigeration effect or heating effect of the air conditioner is affected. In the present application, the heat exchanger 3 is arranged between the air inlet 11 and the inlet 21d, and the fan wheel assembly 20 adopts a suction heat exchange mode for the heat exchanger 3, so that the heat exchange uniformity of the air conditioner 100 is better, and the refrigeration effect or heating effect of the air conditioner 100 is improved.

[0044] As shown in Figures 2-5 The heat insulation component 4 is arranged between the volute 21 and the heat exchanger 3, and the heat insulation component 4 avoids the inlet 21d to enable the airflow passing through the heat exchanger 3 to flow smoothly to the inlet 21d, and the heat insulation component 4 is not easy to interfere with the normal flow direction of the airflow in the air conditioner 100; the heat insulation component 4 is at least arranged on the part opposite to the heat exchanger 3 at the joint position between the first sub-volute 21a and the second sub-volute 21b, the heat insulation component 4 can prevent heat transfer, that is, prevent cold transfer, and the heat insulation component 4 can separate the part of the joint position between the first sub-volute 21a and the second sub-volute 21b opposite to the heat exchanger 3 from the heat exchanger 3, or in other words, the heat insulation component 4 can separate the part of the joint position between the first sub-volute 21a and the second sub-volute 21b close to the heat exchanger 3 from the heat exchanger 3, so that the airflow after heat exchange by the heat exchanger 3 is not easy to directly contact the joint position between the first sub-volute 21a and the second sub-volute 21b. When the heat exchanger 3 is used as an evaporator, the heat insulation component 4 can reduce the cold radiation of the heat exchanger 3 to the joint position between the first sub-volute 21a and the second sub-volute 21b, thereby reducing the possibility of condensate water at the joint position between the first sub-volute 21a and the second sub-volute 21b, and improving the water dripping problem.

[0045] For example, when the air conditioner 100 operates in the cooling mode, the heat exchanger 3 is used as an evaporator, the temperature difference between the heat exchanger 3 and the fan wheel assembly 20 is large, and the temperature of the airflow passing through the heat exchanger 3 is low. The heat insulation component 4 can separate the part of the joint position between the first sub-volute 21a and the second sub-volute 21b opposite to the heat exchanger 3, so that the airflow passing through the heat exchanger 3 is not easy to directly contact the joint position between the first sub-volute 21a and the second sub-volute 21b, thereby reducing the cold radiation of the heat exchanger 3 to the joint position between the first sub-volute 21a and the second sub-volute 21b, and reducing the possibility of condensate water at the joint position between the first sub-volute 21a and the second sub-volute 21b. Of course, in other examples, the heat exchanger 3 can also be used as an outdoor heat exchanger.

[0046] According to the air conditioner 100 in the embodiment of the present application, the heat insulation component 4 can separate the part of the joint position between the first sub-volute 21a and the second sub-volute 21b opposite to the heat exchanger 3 from the heat exchanger 3, so that the airflow passing through the heat exchanger 3 is not easy to directly contact the joint position between the first sub-volute 21a and the second sub-volute 21b, thereby reducing the cold radiation of the heat exchanger 3 to the joint position between the first sub-volute 21a and the second sub-volute 21b, and reducing the possibility of condensate water at the joint position between the first sub-volute 21a and the second sub-volute 21b.

[0047] In some embodiments, the first heat insulation component 40 is detachably connected with the volute 21, the first heat insulation component 40 is not easy to affect the maintenance of the impeller assembly 20, and the installation of the first heat insulation component 40 on the volute 21 is beneficial to reduce the distance between the first heat insulation component 40 and the volute 21, which can improve the heat insulation effect of the first heat insulation component 40 on the corresponding part of the joint position to a certain extent, and meanwhile, the air conditioner 100 does not need to additionally separately set a component for installing the first heat insulation component 40.

[0048] In some embodiments, as shown in Figure 3 and Figures 5-7 one of the first sub-volute 21a and the second sub-volute 21b is detachably connected with the first heat insulation component 40, and the other of the first sub-volute 21a and the second sub-volute 21b is not connected with the first heat insulation component 40, so that the first heat insulation component 40 is not easy to affect the maintenance of the impeller assembly 20, and the structure of the volute 21 can be simplified, and only the structure detachably connected with the first heat insulation component 40 needs to be arranged on one of the first sub-volute 21a and the second sub-volute 21b, and no additional structure matched with the first heat insulation component 40 needs to be arranged on the other.

[0049] For example, when the volute 21 needs to be disassembled, the first heat insulation component 40 can be separated from the volute 21 first, and then the first sub-volute 21a and the second sub-volute 21b are separated, so that the maintenance of the volute 21 and the impeller 22 can be more conveniently completed by the worker, and the maintenance efficiency of the impeller assembly 20 is improved, and when the first heat insulation component 40 needs to be maintained, the first heat insulation component 40 and the volute 21 can be directly separated, and the maintenance convenience and the maintenance efficiency of the first heat insulation component 40 are improved.

[0050] In addition, the installation of the first heat insulation component 40 on the volute 21 is beneficial to reduce the distance between the first heat insulation component 40 and the volute 21, which can improve the heat insulation effect of the first heat insulation component 40 on the corresponding part of the joint position to a certain extent, and meanwhile, the air conditioner 100 does not need to additionally separately set a component for installing the first heat insulation component 40.

[0051] In some embodiments, as shown in Figure 3 and Figures 5-11As shown, the first thermal insulation piece 40 comprises a main body part 41 and a hooking part 42, the main body part 41 extends along the extension direction of the splicing position, and the main body part 41 abuts against the splicing position, and the length ends of the main body part 41 are respectively provided with the hooking parts 42, and the hooking parts 42 are hookingly matched in the volute 21. Exemplarily, the hooking parts 42 are hookingly matched in one of the first sub-volute 21a and the second sub-volute 21b.

[0052] It can be seen that the main body part 41 abuts against the splicing position, so that the air flow passing through the heat exchanger 3 is not easy to contact the splicing position through the gap between the first thermal insulation piece 40 and the volute 21, so as to reduce the cold radiation of the heat exchanger 3 to the splicing position between the first sub-volute 21a and the second sub-volute 21b, and facilitate to improve the thermal insulation effect of the first thermal insulation piece 40.

[0053] It can be understood that the main body part 41 abutting against the splicing position can refer to that the main body part 41 directly abuts against the splicing position, or the main body part 41 indirectly abuts against the splicing position through other components (for example, the fourth heat exchange piece described below, and the main body part 41 indirectly abuts against the splicing position through the fourth heat exchange piece).

[0054] In addition, the length ends of the main body part 41 are provided with the hooking parts 42, and the hooking parts 42 are hookingly matched in the volute 21, by providing the length ends of the main body part 41 with the hooking parts 42, so that the cooperation between the first thermal insulation piece 40 and the volute 21 is more stable, and the first thermal insulation piece 40 and the volute 21 are not easy to be separated, and the hooking parts 42 allow the main body part 41 to be quickly assembled in the volute 21 by simple hooking, without the need for complex bolts or welding, so as to facilitate to simplify the assembly and disassembly process of the first thermal insulation piece 40.

[0055] The first thermal insulation piece 40 further comprises a limiting part 43, and the length ends of the main body part 41 are respectively provided with the limiting parts 43 corresponding to the hooking parts 42, for example, the limiting parts 43 and the hooking parts 42 are one-to-one correspondingly arranged. The limiting part 43 has a limiting state and a release state, in the limiting state, the limiting part 43 is limitedly matched with the volute 21 to limit the hooking part 42 from being separated from the volute 21, so that the first thermal insulation piece 40 and the volute 21 are not easy to be separated, even if the air conditioner 100 is subjected to vibration or external force impact, the limiting part 43 can still limit the first thermal insulation piece 40 from being separated from the volute 21, so that the setting position of the first thermal insulation piece 40 is more stable, and the first thermal insulation piece 40 can provide stable thermal insulation effect for the splicing position; in the release state, the limiting part 43 releases the limitation on the hooking part 42, so that the first thermal insulation piece 40 can be separated from or assembled in the volute 21 through the hooking part 42, so as to make the disassembly of the first thermal insulation piece 40 more convenient, and facilitate to improve the disassembly efficiency of the first thermal insulation piece 40.

[0056] It can be seen that by providing the limiting portion 43 and providing the limiting portion 43 with the limiting state and the release state, the limiting portion 43 can be switched to the corresponding state according to the disassembly requirement of the first heat insulation piece 40, so that the locking and stable installation of the first heat insulation piece 40 are realized, and the self-locking of the first heat insulation piece 40 is realized, and meanwhile, the first heat insulation piece 40 is not affected to be disassembled from the volute 21.

[0057] Compared with some technologies, the possibility of condensate water at the splicing position of the volute is reduced by wrapping the sponge at the splicing position, and the above structure of the first heat insulation piece 40 of the present application is not suitable for using the sponge, and relatively, the structure is convenient to improve the risk of easy tearing of the sponge.

[0058] In some embodiments, as shown in Figure 8 and Figure 9 The limiting portion 43 is configured as an elastic part, and the elastic part is always in the limiting state to limit the first heat insulation piece 40 from being disassembled from the volute 21. The limiting portion 43 can stably limit the hooking portion 42, so that the setting position of the first heat insulation piece 40 is more stable, and the first heat insulation piece 40 can provide stable heat insulation effect for the splicing position. It can be understood that the elastic part is always in the limiting state in the normal state, for example, the elastic part is always in the limiting state in the natural state when the elastic part is not subjected to any external force. For example, when the first heat insulation piece 40 is installed on the volute 21, the elastic part is elastically deformed under the reaction force of the volute 21 to switch to the limiting state, at this time, the elastic part is not subjected to other external forces, and the elastic part remains in the limiting state; and / or, as shown in Figure 8 and Figure 9 The main body portion 41 and the hooking portion 42 are respectively formed as a plate structure, and the limiting portion 43 is formed as a spring structure. The first heat insulation piece 40 is an integral bending molded part.

[0059] Exemplarily, the limiting portion 43 is configured as an elastic part, the length of the main body portion 41 is respectively cantilevered at both ends of the length of the main body portion 41, the fixed end of the elastic part is located at one end of the length of the main body portion 41, the free end of the elastic part extends in a direction away from the main body portion 41, and the free end of the elastic part extends obliquely towards the other elastic part. When no external force acts on the elastic part, the elastic parts at both ends of the length of the main body portion 41 can always be clamped to the volute 21 and be in the limiting state, so that the hooking portion 42 is not easy to be disengaged from the volute 21, and the stability of the first heat insulation piece 40 is improved. When the first heat insulation piece 40 needs to be disassembled, an external force away from the other elastic part can be applied to the free end of the elastic part, so that the elastic part is switched from the limiting state to the release state, and the subsequent disassembly of the first heat insulation piece 40 is facilitated.

[0060] The main body part 41 and the hooking part 42 are formed in a plate structure, the structure of the main body part 41 and the hooking part 42 is relatively simple, and the main body part 41 and the hooking part 42 are convenient to process and manufacture; the limiting part 43 is formed in a spring structure, the spring structure can be directly stamped or cut to form, the spring structure can be manufactured integrally with the main body part 41 and the hooking part 42, the manufacturing efficiency of the first heat insulation piece 40 is improved, and the spring structure can generate a sustained elastic force through elastic deformation, so that the limiting part 43 can stably limit the hooking part 42, and the setting position of the first heat insulation piece 40 is more stable; the first heat insulation piece 40 is an integral bending forming piece, that is, the main body part 41, the hooking part 42 and the limiting part 43 are integrally formed, there is no welding seam or riveting point between the parts of the first heat insulation piece 40, the structural strength of the first heat insulation piece 40 is good, the reliability of the first heat insulation piece 40 is improved, the first heat insulation piece 40 is processed and manufactured through an integral bending forming process, the processing and manufacturing of the first heat insulation piece 40 is relatively simple, the production efficiency of the first heat insulation piece 40 is improved, and the large-scale production and manufacturing of the first heat insulation piece 40 is facilitated.

[0061] In some embodiments, as shown in Figure 3 , Figures 5-7 , Figure 10 and Figure 11 , the outer surface of the volute 21 has a protrusion 27, the protrusion 27 is formed with a clamping hole 23b, and the hooking part 42 is hookingly matched in the clamping hole 23b; in the limiting state, the limiting part 43 abuts against one side of the protrusion 27 away from the hooking part 42, and in the releasing state, the limiting part 43 is located on the outer peripheral side of the protrusion 27 to avoid the protrusion 27.

[0062] It can be seen that when the limiting part 43 is in the limiting state, the limiting part 43 abuts against one side of the protrusion 27 away from the hooking part 42, and the limiting part 43 and the hooking part 42 are located on the two sides of the protrusion 27 respectively, when the hooking part 42 is subjected to an external force or vibration, the hooking part 42 can move away from the protrusion 27, at this time, the limiting part 43 is limited, so that the limiting part 43 can limit the movement of the hooking part 42 away from the protrusion 27, the setting position of the first heat insulation piece 40 is more stable, and the first heat insulation piece 40 can provide stable heat insulation effect on the splicing position; when the limiting part 43 is in the releasing state, the limiting part 43 is located on the outer peripheral side of the protrusion 27, and the limiting part 43 can avoid the protrusion 27, at this time, the hooking part 42 can move away from the protrusion 27, so that the first heat insulation piece 40 and the volute 21 are separated, and the subsequent maintenance of the wind wheel assembly 20 is facilitated.

[0063] In some embodiments, as shown in Figure 3 and Figures 5-7 , the first sub-volute 21a and the second sub-volute 21b are perpendicular to the axial direction of the wind wheel 22 (for example, the axial direction of the wind wheel 22 is parallel to the vertical direction of the wind turbine 1), and the first sub-volute 21a and the second sub-volute 21b are arranged on the same side of the wind wheel 22.Figure 3 The first direction is opposite to the extending direction of the straight line L1 in the first direction) so that the first sub-volute 21a and the second sub-volute 21b define the inlet 21d opposite to a part of the heat exchanger 3. The first heat insulation part 40 further comprises a reinforcing part 44, at least one end of the main body part 41 is provided with the reinforcing part 44, the reinforcing part 44 is arranged on the side of the hooking part 42 away from the limiting part 43, or the reinforcing part 44 is arranged on the side of the limiting part 43 away from the hooking part 42, and the reinforcing part 44 is bent and extends towards the inlet 21d.

[0064] It can be seen that the first sub-volute 21a and the second sub-volute 21b define the inlet 21d opposite to a part of the heat exchanger 3, and the splicing position part of the first sub-volute 21a and the second sub-volute 21b is located at the inlet 21d. At least one end of the main body part 41 is provided with the reinforcing part 44, so that the reinforcing part 44 can better cover the splicing position part located at the outer edge of the inlet 21d, so that the covering area of the first heat insulation part 40 is larger, and the airflow passing through the heat exchanger 3 cannot easily affect the splicing position part located at the inlet 21d, so that the first heat insulation part 40 can have a better heat insulation effect.

[0065] In addition, the reinforcing part 44 is arranged on the side of the hooking part 42 away from the limiting part 43, so that the reinforcing part 44 and the limiting part 43 are located on opposite sides of the limiting part 43, so that the structure of the first heat insulation part 40 is more compact, and the first heat insulation part 40 is not easy to interfere with the arrangement of other components. Or, the reinforcing part 44 is arranged on the side of the limiting part 43 away from the hooking part 42, so that the reinforcing part 44 and the hooking part 42 are located on opposite sides of the limiting part 43, so that the structural strength of the limiting part 43 can be enhanced, so that the limiting part 43 can provide stable limiting action to the hooking part 42. Therefore, the arrangement position of the reinforcing part 44 is more flexible, which is convenient for adapting to different installation conditions. In addition, the arrangement of the above-mentioned reinforcing part 44 can increase the covering area of the first heat insulation part 40, so as to improve the heat insulation effect of the first heat insulation part 40.

[0066] The reinforcing part 44 is bent and extends towards the inlet 21d, so that the angle between the reinforcing part 44 and the airflow at the inlet 21d is relatively small, which is conducive to reducing the blocking effect of the reinforcing part 44 on the airflow at the inlet 21d, so that the airflow at the inlet 21d is not easily disturbed by the reinforcing part 44, so that the air conditioner 100 has good air volume. In addition, the reinforcing part 44 can guide the airflow to the inlet 21d to a certain extent, so that the airflow passing through the heat exchanger 3 cannot easily contact the surrounding area of the splicing position, so as to improve the heat insulation effect of the first heat insulation part 40.

[0067] It can be understood that one end of the length of the main body part 41 can be provided with the reinforcing part 44, or both ends of the length of the main body part 41 can be provided with the reinforcing part 44, so as to adapt to different use conditions. For example, when the volute 21 is axially ventilated on one side, one end of the length of the main body part 41 corresponding to the inlet 21d can be provided with the reinforcing part 44; for another example, when the volute 21 is axially ventilated on both sides, both ends of the length of the main body part 41 can be provided with the reinforcing part 44.

[0068] Exemplarily, the reinforcing part 44 is a plate structure, the main body part 41 and the hooking part 42 are also respectively formed into plate structures, the limiting part 43 is formed into a spring structure, and the first heat insulation piece 40 is an integral bending forming piece. The main body part 41, the hooking part 42, the reinforcing part 44 and the limiting part 43 are integrally formed, and there is no welding seam or riveting point between the parts of the first heat insulation piece 40, so that the structural strength of the first heat insulation piece 40 is better, the reliability of the first heat insulation piece 40 is improved, the first heat insulation piece 40 is processed and manufactured through the integral bending forming process, the processing and manufacturing of the first heat insulation piece 40 is simpler, the production efficiency of the first heat insulation piece 40 is improved, and the large-scale production and manufacturing of the first heat insulation piece 40 is facilitated.

[0069] In some embodiments, as shown in Figures 5-7 , Figure 10 and Figure 11 , the first sub-volute 21a and the second sub-volute 21b are detachably connected through the buckle structure 23, the buckle structure 23 includes the hook 23a and the clamping hole 23b, the hook 23a extends into the clamping hole 23b, and the hook 23a is arranged at the edge part of the clamping hole 23b. The first heat insulation piece 40 is arranged around at least one buckle structure 23, and the hooking part 42 is hookingly matched in the clamping hole 23b.

[0070] It can be seen that the first sub-volute 21a and the second sub-volute 21b are connected through the buckle structure 23. When the hook 23a is arranged at the edge part of the clamping hole 23b, the first sub-volute 21a and the second sub-volute 21b are assembled. When the hook 23a is separated from the clamping hole 23b, the first sub-volute 21a and the second sub-volute 21b are separated, so that the disassembly of the first sub-volute 21a and the second sub-volute 21b is more convenient, and the maintenance efficiency of the wind wheel assembly 20 is improved.

[0071] Further, the first thermal insulation member 40 is arranged around the buckle structure 23, so that the first thermal insulation member 40 covers the buckle structure 23, and the air flow passing through the heat exchanger 3 is less likely to contact the buckle structure 23, thereby reducing the cold radiation of the heat exchanger 3 to the buckle structure 23, and facilitating to improve the thermal insulation effect of the first thermal insulation member 40; the hooking portion 42 is hookingly fitted in the clamping hole 23b, so that the hooking portion 42 and the clamping hook 23a can share the clamping hole 23b, and a hole for the hooking portion 42 does not need to be additionally machined on the volute 21, so that the machining and manufacturing of the volute 21 can be more convenient, and the manufacturing efficiency of the volute 21 can be improved.

[0072] It can be understood that the clamping hook 23a can be located on one of the first sub-volute 21a and the second sub-volute 21b, and the clamping hole 23b is located on the other one of the first sub-volute 21a and the second sub-volute 21b.

[0073] For example, the first sub-volute 21a and the second sub-volute 21b are vertically arranged (the first direction is the vertical direction), the second sub-volute 21b is located below the first sub-volute 21a, the clamping hook 23a is formed on the outer surface of the second sub-volute 21b, the clamping hook 23a extends along the second sub-volute 21b towards the first sub-volute 21a, the clamping hole 23b is formed on the protrusion 27 of the outer surface of the first sub-volute 21a, the clamping hook 23a can extend into the clamping hole 23b from bottom to top, and then the clamping hook 23a is hooked on the edge portion at the top of the clamping hole 23b, and there is a certain empty space between the clamping hook 23a and the clamping hole 23b, the hooking portion 42 extends along the first sub-volute 21a towards the second sub-volute 21b, and then the hooking portion 42 extends into the clamping hole 23b from top to bottom, and then the hooking portion 42 is hooked on the edge portion of the empty space between the clamping hook 23a and the clamping hole 23b.

[0074] In some embodiments, as shown in Figure 5 and Figure 7 , the first sub-volute 21a and the second sub-volute 21b are connected by the buckle structure 23, the buckle structure 23 includes the clamping hook 23a and the clamping hole 23b, the clamping hook 23a extends into the clamping hole 23b, and the clamping hook 23a is hooked on the edge portion of the clamping hole 23b, the hooking portion 42 is hookingly fitted in the clamping hole 23b, and the volute 21 further includes the reinforcing structure 26, the reinforcing structure 26 is arranged adjacent to the clamping hole 23b.

[0075] It can be seen that the reinforcing structure 26 is arranged adjacent to the clamping hole 23b, the reinforcing structure 26 can enhance the structural strength and stability of the clamping hole 23b, which is conducive to further improving the installation reliability of the clamping hook 23a, the hooking portion 42 and the clamping hole 23b, and when the clamping hook 23a and the hooking portion 42 need to be frequently disassembled and assembled, the clamping hole 23b is less likely to be deformed greatly during the disassembly and assembly process, so that the structure of the clamping hole 23b is more stable, and the reliability of the air conditioner 100 can be improved.

[0076] It can be understood that the reinforcing structure 26 can refer to locally thickening the edge portion of the card hole 23b, or the reinforcing structure 26 refers to providing a reinforcing rib at the edge portion of the card hole 23b.

[0077] In some embodiments, as shown in Figure 3 and Figure 4 The first sub-volute 21a includes a first volute portion 24a and a first fitting portion 24b, the first fitting portion 24b is arranged at the end of the first volute portion 24a, and the first fitting portion 24b protrudes from the outer surface of the first volute portion 24a. The second sub-volute 21b includes a second volute portion 25a and a second fitting portion 25b, the second fitting portion 25b is arranged at the end of the second volute portion 25a, and the second fitting portion 25b protrudes from the outer surface of the second volute portion 25a. The first fitting portion 24b and the second fitting portion 25b are inserted and fitted, and the first fitting portion 24b and the second fitting portion 25b form a splicing position.

[0078] It can be seen that the first fitting portion 24b and the second fitting portion 25b are arranged at the end, so that the first fitting portion 24b and the second fitting portion 25b can better contact to realize the splicing of the first sub-volute 21a and the second sub-volute 21b. After the first fitting portion 24b and the second fitting portion 25b are inserted and fitted, the splicing position can form a fitting form similar to a stop structure. The airflow of the wind wheel assembly 20 is not easy to leak through the splicing position, and the wind wheel assembly 20 can have good air volume, thereby facilitating to improve the refrigeration effect or heating effect of the air conditioner 100.

[0079] Among them, in the opposite direction (for example, the first direction) of the first sub-volute 21a and the second sub-volute 21b, the size (for example, L2 in Figure 4 ) of the first heat insulation piece 40 is greater than or equal to the distance (for example, L3 in Figure 4 ) between the side surfaces of the first fitting portion 24b and the second fitting portion 25b away from each other, then the first heat insulation piece 40 at least covers the first fitting portion 24b and the second fitting portion 25b, and the first heat insulation piece 40 at least covers the corresponding part of the splicing position, so that the airflow passing through the heat exchanger 3 is not easy to contact the splicing position, thereby reducing the cold radiation of the heat exchanger 3 to the splicing position, and the inside of the volute 21 opposite to the splicing position is not easy to produce condensed water, thereby facilitating to improve the reliability of the operation of the air conditioner 100. In addition, since the first fitting portion 24b protrudes from the outer surface of the first volute portion 24a, and the second fitting portion 25b protrudes from the outer surface of the second volute portion 25a, the sizes of the first fitting portion 24b and the second fitting portion 25b are relatively large, thereby facilitating to realize the splicing reliability of the splicing position of the volute 21, and meanwhile not easy to affect the transition of the wall surface of the wind wheel cavity 21c at the splicing position.

[0080] In some embodiments, the air conditioner 100 further comprises a second heat insulation member, the second heat insulation member is arranged on the outer surface of the first volute portion 24a, and at least a part of the second heat insulation member is arranged on the side of the first sub-volute 21a facing the heat exchanger 3, the second heat insulation member is partially overlapped with the first heat insulation member 40, in the opposite direction of the first sub-volute 21a and the second sub-volute 21b, the size of the first heat insulation member 40 is greater than the distance between the side surfaces of the first fitting portion 24b and the second fitting portion 25b facing away from each other, and a part of the first heat insulation member 40 is arranged corresponding to the first volute portion 24a, so that the above-mentioned part of the first heat insulation member 40 is overlapped with the second heat insulation member at the position corresponding to the outer surface of the first volute portion 24a; and / or, the air conditioner 100 further comprises a third heat insulation member, the third heat insulation member is arranged on the outer surface of the second volute portion 25a, and at least a part of the third heat insulation member is arranged on the side of the second sub-volute 21b facing the heat exchanger 3, the third heat insulation member is partially overlapped with the first heat insulation member 40, in the opposite direction of the first sub-volute 21a and the second sub-volute 21b, the size of the first heat insulation member 40 is greater than the distance between the side surfaces of the first fitting portion 24b and the second fitting portion 25b facing away from each other, and a part of the first heat insulation member 40 is arranged corresponding to the second volute portion 25a, so that the above-mentioned part of the first heat insulation member 40 is overlapped with the third heat insulation member at the position corresponding to the outer surface of the second volute portion 25a.

[0081] At least a part of the second heat insulation member is arranged on the side of the first volute portion 24a facing the heat exchanger 3, so that the second heat insulation member can reduce the radiation of cold energy of the heat exchanger 3 to the first sub-volute 21a, and the second heat insulation member is partially overlapped with the first heat insulation member 40, in the direction of the first heat insulation member 40 facing the first sub-volute 21a, a part of the second heat insulation member and a part of the first heat insulation member 40 can be overlapped in the direction from the volute 21 to the heat exchanger 3, so that the second heat insulation member and the first heat insulation member 40 can achieve a larger range of heat insulation for the first sub-volute 21a, and reduce the possibility of condensate water in the first sub-volute 21a, and because the first fitting portion 24b protrudes from the outer surface of the first volute portion 24a, and the second fitting portion 25b protrudes from the outer surface of the second volute portion 25a, it is convenient to appropriately increase the distance between the first heat insulation member 40 and the first volute portion 24a, so as to leave a certain space for the second heat insulation member, and realize the partial overlap of the second heat insulation member and the first heat insulation member 40. Of course, in other embodiments of the present application, the second heat insulation member and the first heat insulation member 40 are not overlapped, for example, in the direction of the first heat insulation member 40 facing the first sub-volute 21a, the edges of the second heat insulation member and the first heat insulation member 40 are in abutting fit.

[0082] It can be understood that the second heat insulation member can be arranged on the side of the first volute portion 24a facing the heat exchanger 3, or the second heat insulation member can be arranged on the entire outer surface of the first volute portion 24a, that is, the side of the first volute portion 24a away from the heat exchanger 3 can also be provided with the second heat insulation member, so that the coverage of the second heat insulation member is larger, and the heat insulation effect of the second heat insulation member is facilitated.

[0083] At least part of the third heat insulation member is arranged on the side of the second volute portion 25a facing the heat exchanger 3, so that the third heat insulation member can reduce the radiation of cold energy of the heat exchanger 3 to the second sub-volute 21b. The third heat insulation member is partially overlapped with the first heat insulation member 40, and then in the direction of the first heat insulation member 40 facing the second sub-volute 21b, part of the third heat insulation member and part of the first heat insulation member 40 can be overlapped in the direction from the volute 21 to the heat exchanger 3, so that the third heat insulation member and the first heat insulation member 40 can achieve a larger range of heat insulation for the second sub-volute 21b, and reduce the possibility of condensate water in the second sub-volute 21b. Moreover, since the first fitting portion 24b protrudes from the outer surface of the first volute portion 24a, and the second fitting portion 25b protrudes from the outer surface of the second volute portion 25a, the spacing between the first heat insulation member 40 and the second volute portion 25a is appropriately increased, so as to leave a certain space for the third heat insulation member, and the third heat insulation member and the first heat insulation member 40 are partially overlapped. Of course, in other embodiments of the present application, the third heat insulation member and the first heat insulation member 40 are not overlapped, for example, in the direction of the first heat insulation member 40 facing the second sub-volute 21b, the edges of the third heat insulation member and the first heat insulation member 40 are in abutting fit.

[0084] It can be understood that the third heat insulation member can be arranged on the side of the second volute portion 25a facing the heat exchanger 3, or the third heat insulation member can be arranged on the entire outer surface of the second volute portion 25a, that is, the side of the second volute portion 25a away from the heat exchanger 3 can also be provided with the third heat insulation member, so that the coverage of the third heat insulation member is larger, and the heat insulation effect of the third heat insulation member is facilitated.

[0085] Optionally, each of the second heat insulation member and the third heat insulation member is thermal foam or thermal sponge. Both the thermal foam and the thermal sponge have good heat insulation performance, and both the thermal foam and the thermal sponge have good deformation ability, so as to adapt to different installation environments.

[0086] In some embodiments, the first heat insulation member 40 is a plastic member or a metal member.

[0087] It can be seen that when the first thermal insulation piece 40 is a plastic piece, the thermal conductivity of the plastic piece is low, and the density of the plastic piece is small, so that the weight of the first thermal insulation piece 40 is light, the disassembly and assembly of the first thermal insulation piece 40 are facilitated, and the plastic piece can be formed by injection molding, so that the processing and manufacturing of the first thermal insulation piece 40 are more convenient, and the manufacturing efficiency of the first thermal insulation piece 40 is improved; when the first thermal insulation piece 40 is a metal piece, for example, the first thermal insulation piece 40 is a galvanized sheet or stainless steel, the structural strength of the metal piece is better, so that the first thermal insulation piece 40 is not easily damaged in use, and the service life of the first thermal insulation piece 40 is improved. Further, the first thermal insulation piece 40 is a galvanized sheet or stainless steel, and a thermal insulation paint is sprayed, so that the thermal insulation effect of the first thermal insulation piece 40 is better.

[0088] In some technologies, sponge is wrapped around the spliced position of the volute to reduce the possibility of condensate water at the spliced position, but when the first sub-volute and the second sub-volute need to be disassembled and assembled, the sponge wrapped around the spliced position between the first sub-volute and the second sub-volute is prone to be torn, so that condensate water is still easily generated inside the volute during subsequent use of the air conditioner, causing the blowing water phenomenon of the air conditioner, affecting the reliability of the air conditioner, and the maintenance of the fan assembly is also more complicated.

[0089] The first thermal insulation piece 40 of the present application is a plastic piece or a metal piece, and the first thermal insulation piece 40 separates the part of the spliced position between the first sub-volute 21a and the second sub-volute 21b opposite the heat exchanger 3 from the heat exchanger 3, so that sponge does not need to be wrapped around the spliced position between the first sub-volute 21a and the second sub-volute 21b, and the first thermal insulation piece 40 is not easily damaged during disassembly and assembly of the first sub-volute 21a and the second sub-volute 21b, so that the disassembly and assembly of the first sub-volute 21a and the second sub-volute 21b are more convenient, and the maintenance efficiency of the fan assembly 20 is improved.

[0090] In some embodiments, the air conditioner 100 further comprises a fourth thermal insulation piece arranged on the side surface of the first thermal insulation piece 40 facing the volute 21, and the thermal insulation performance of the fourth thermal insulation piece is better than that of the first thermal insulation piece 40.

[0091] It can be seen that the fourth thermal insulation piece is arranged on the side surface of the first thermal insulation piece 40 facing the volute 21, the first thermal insulation piece 40 is at least arranged on the part of the spliced position between the first sub-volute 21a and the second sub-volute 21b opposite the heat exchanger 3, and the fourth thermal insulation piece is located between the first thermal insulation piece 40 and the spliced position, so that the fourth thermal insulation piece can further increase the heat transfer thermal resistance between the heat exchanger 3 and the spliced position, and the double thermal insulation of the first thermal insulation piece 40 and the fourth thermal insulation piece is conducive to reducing the cold radiation of the heat exchanger 3 to the spliced position, so that the condensate water is not easily generated inside the volute 21 opposite the spliced position, and the reliability of the air conditioner 100 in operation is improved.

[0092] In addition, the fourth heat insulation member has better heat insulation performance than the first heat insulation member 40, and can effectively reduce the cold energy transfer from the heat exchanger 3 to the splicing position. Even if the heat insulation performance of the first heat insulation member 40 is damaged, the fourth heat insulation member can still effectively reduce the cold energy transfer between the heat exchanger 3 and the splicing position, so that the condensate water is not easily generated inside the volute 21 opposite to the splicing position, and the reliability of the air conditioner 100 in operation is improved.

[0093] Optionally, the fourth heat insulation member is heat insulation foam or heat insulation sponge.

[0094] In some embodiments, as shown in Figures 3-5 The air conditioner 100 includes a first heat insulation member 40, a second heat insulation member, a third heat insulation member, and a fourth heat insulation member. The first sub-volute 21a includes a first volute portion 24a and a first fitting portion 24b, and the second sub-volute 21b includes a second volute portion 25a and a second fitting portion 25b. The first fitting portion 24b and the second fitting portion 25b are inserted and fitted to form a splicing position. The first heat insulation member 40 is arranged on the part of the splicing position opposite to the heat exchanger 3. The second heat insulation member is arranged on the outer surface of the first volute portion 24a, and partially overlaps the first heat insulation member 40. The third heat insulation member is arranged on the outer surface of the second volute portion 25a, and partially overlaps the first heat insulation member 40. The fourth heat insulation member is arranged on the side surface of the first heat insulation member 40 facing the volute 21. The second heat insulation member and the third heat insulation member can reduce the heat transfer from the heat exchanger 3 to the part of the volute 21 except the splicing position, and reduce the cold energy radiation from the heat exchanger 3 to the part of the volute 21 except the splicing position, so that the condensate water is not easily generated inside the part of the volute 21 except the splicing position. In addition, the first heat insulation member 40, the second heat insulation member, the third heat insulation member, and the fourth heat insulation member can play a certain heat insulation role for the volute 21, so that the condensate water is not easily generated inside the volute 21, and the stability of the air conditioner 100 in operation is improved.

[0095] In some embodiments, as shown in

[0096] In some embodiments, as shown in Figure 3 and Figure 4As shown, the first sub-volute 21a and the second sub-volute 21b are spliced to define the inlet 21d, and the outlet 21e is formed on the side of the second sub-volute 21b away from the first sub-volute 21a, for example, the first sub-volute 21a and the second sub-volute 21b are spliced along a first direction perpendicular to the axial direction of the impeller 22 (for example, the first direction is the up-down direction), the outlet 21e is located on the side of the second sub-volute 21b away from the first sub-volute 21a in the first direction, and the first sub-volute 21a and the second sub-volute 21b jointly define the inlet 21d on at least one side of the axial direction of the volute 21 after being spliced; or, the first sub-volute 21a and the second sub-volute 21b are spliced to define the outlet 21e, and at least one of the first sub-volute 21a and the second sub-volute 21b is provided with the inlet 21d, for example, the first sub-volute 21a and the second sub-volute 21b are spliced along the axial direction of the impeller 22 (for example, the horizontal direction), the first sub-volute 21a and the second sub-volute 21b jointly define the outlet 21e after being spliced, and the inlet 21d is formed on the side of the first sub-volute 21a away from the second sub-volute 21b in the axial direction, or the inlet 21d is formed on the side of the second sub-volute 21b away from the first sub-volute 21a in the axial direction, or the first sub-volute 21a and the second sub-volute 21b are away from each other in the axial direction and are respectively provided with the inlet 21d.

[0097] It can be seen that the application does not limit the splicing mode of the volute 21, and the user can select according to the actual installation environment, thereby facilitating the improvement of the applicability of the volute 21.

[0098] In some embodiments, as shown in Figures 1-4 The air conditioner 100 is a ceiling type air conditioner 100, the air outlet 12 is located on the lower side of the shell 1, the outlet 21e is located on the lower side of the volute 21, and the outlet 21e is formed on the side of the second sub-volute 21b away from the first sub-volute 21a.

[0099] It can be seen that the air conditioner 100 is a ceiling type air conditioner 100, for example, the air conditioner 100 is a kitchen air conditioner, etc., the second sub-volute 21b is located below the first sub-volute 21a, the first sub-volute 21a and the second sub-volute 21b are spliced along the up-down direction, the airflow can directly flow to the air outlet 12 through the outlet 21e, the flow path of the airflow is more clear, and it is not necessary to additionally arrange a duct between the outlet 21e and the air outlet 12 to change the flow direction of the airflow, thereby facilitating the improvement of the structure of the air conditioner 100 and the manufacturing efficiency of the air conditioner 100.

[0100] In some embodiments, as shown in Figure 2 and Figure 3As shown, the heat exchanger 3 comprises a first heat exchange portion 30 and two second heat exchange portions 31, the two second heat exchange portions 31 are opposite along the axial direction of the fan wheel 22, each second heat exchange portion 31 is bently connected to the first heat exchange portion 30, the air supply component 2 is arranged between the two second heat exchange portions 31, the air supply component 2 comprises two fan wheel assemblies 20 arranged along the axial direction of the fan wheel 22, each fan wheel cavity 21c has an inlet 21d on each axial side, the outlets 21e of the two fan wheel cavities 21c are arranged towards the same side of the air conditioner 100, and each volute 21 corresponds to a heat insulation component 4. It can be understood that the axial direction of the fan wheel cavity 21c is the axial direction of the fan wheel 22.

[0101] As can be seen, each second heat exchange portion 31 is bently connected to the first heat exchange portion 30, for example, the heat exchanger 3 is formed in a "U" shape, etc., the air supply component 2 is arranged between the two second heat exchange portions 31, so that the air supply component 2 is located in the "U" shaped space formed by the heat exchanger 3, and the axial direction of the fan wheel cavity 21c has an inlet 21d on each axial side, so that the airflow passing through the heat exchanger 3 can flow into the fan wheel cavity 21c through the inlets 21d on both axial ends of the fan wheel cavity 21c, and then flow to the air outlet 12 of the air conditioner 100 through the outlet 21e.

[0102] In addition, the outlets 21e of the two fan wheel cavities 21c are arranged towards the same side of the air conditioner 100, so that the airflow passing through the outlet 21e can be more concentrated, which is convenient for improving the air volume of the air conditioner 100 and is beneficial to improve the refrigeration effect or heating effect of the air conditioner 100.

[0103] Each volute 21 corresponds to a heat insulation component 4, and the heat insulation component 4 is located at the portion opposite to the heat exchanger 3 at the splicing position of the volute 21, so that the heat insulation component 4 can effectively reduce the heat transfer between the heat exchanger 3 and the splicing position, and reduce the possibility of condensate water in the volute 21 opposite to the splicing position, which is convenient for improving the stability of the air conditioner 100.

[0104] Optionally, the fan wheel 22 is a centrifugal fan, and the inlet and outlet modes of the centrifugal fan and the arrangement form of the above-mentioned heat exchanger 3 can be more matched, which is convenient for improving the refrigeration effect or heating effect of the air conditioner 100.

[0105] In some embodiments, as Figure 2 , Figure 3 and Figure 5As shown, the air supply component 2 further comprises a motor assembly 60, the motor assembly 60 comprises a double-shaft motor, the impellers 22 of the two impeller assemblies 20 are respectively connected to the two axial ends of the double-shaft motor, that is, the double-shaft motor is located between the two impeller assemblies 20, and the double-shaft motor can simultaneously drive the two impellers 22 to rotate, so that the air volume and air speed of the two impeller assemblies 20 are relatively uniform, which is beneficial to the uniformity of indoor temperature, and the double-shaft motor can make more full use of the space between the two impeller assemblies 20, so that the structure of the air supply component 2 is more compact, and the miniaturization design of the air conditioner 100 is facilitated.

[0106] In other embodiments of the present application, the motor assembly 60 comprises a first motor and a second motor, the first motor is connected to the impeller 22 of one of the impeller assemblies 20, and the second motor is connected to the impeller 22 of the other impeller assembly 20, so that the control of the impellers 22 of the impeller assemblies 20 is more independent, and the user can adjust the opening and closing and air speed of the impellers 22 according to actual needs. For example, when the user's requirement for air volume is not too large, only one impeller 22 can be operated at this time, and when the user's requirement for air volume is larger, two impellers 22 can be operated at the same time.

[0107] In some embodiments, as shown, Figures 2-4 As shown, the first sub-volute 21a and the second sub-volute 21b are sequentially arranged along a first direction perpendicular to the axial direction of the impeller 22, and the side of the second sub-volute 21b away from the first sub-volute 21a defines an outlet 21e. Each volute 21 corresponds to one first heat insulation piece 40 or two first heat insulation pieces 40 arranged along a second direction, and the first direction and the axial direction of the impeller 22 are perpendicular to the second direction, respectively.

[0108] As can be seen, each volute 21 corresponds to one first heat insulation piece 40 or two first heat insulation pieces 40 arranged along a second direction, and the first heat insulation piece 40 can effectively reduce the heat transfer between the heat exchanger 3 and the splicing position. For example, in the second direction, when the heat exchanger 3 and the volute 21 are partially misaligned, at least part of the volute 21 is not arranged opposite to the heat exchanger 3. At this time, the volute 21 can be provided with only one first heat insulation piece 40, and the first heat insulation piece 40 is arranged at the part of the volute 21 opposite to the heat exchanger 3. When the heat exchanger 3 and the volute 21 are completely arranged opposite to each other, the volute 21 can be provided with two first heat insulation pieces 40, and the first heat insulation pieces 40 are arranged on both sides of the splicing position of the volute 21 in the second direction.

[0109] Therefore, through the arrangement of the above-mentioned first heat insulation piece 40, the arrangement position of the first heat insulation piece 40 is more flexible, and the staff can determine the number of first heat insulation pieces 40 according to the relative position of the volute 21 and the heat exchanger 3, so that the first heat insulation piece 40 can play a stable heat insulation effect on the splicing position.
