An air conditioner consists of a fan assembly and an evaporator. The fan assembly delivers air to the evaporator, where it exchanges heat, achieving cooling or heating.

[0003] However, in the prior art, the airflow blown out by the fan assembly will impact the evaporator, causing the fins of the evaporator to vibrate, generating noise, and affecting the user experience. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides an air conditioner, which aims to at least solve to a certain extent the technical problem that the airflow blown out by the fan assembly will impact the evaporator, causing the evaporator fins to vibrate, generate noise, and affect the user experience.

[0005] The technical solution of the present invention is:

[0039] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0040] The air conditioner provided in this embodiment is intended to at least to some extent solve the technical problem that the airflow blown out by the fan assembly may impact the evaporator, causing the evaporator fins to vibrate, generate noise, and affect the user experience.

[0041] Figure 1 is a schematic structural diagram of an air conditioner according to some embodiments; Figure 2 for Figure 1 A top view of the air conditioner; Figure 3 for Figure 2 AA cross-sectional view of the middle air conditioner; Figure 4 for Figure 1 Schematic diagram of the connection between the middle partition and the first volute of the middle air conditioner; Figure 9 for Figure 4 The rectifier principle diagram of the rectifier. Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 9 The air conditioner of the embodiment of the present application includes: a shell 10, a middle partition 20, a heat exchanger 30, a fan assembly 40 and a straightening member 50. The middle partition 20 is arranged in the shell 10 to form a first chamber 101 and a second chamber 102. The heat exchanger 30 is arranged in the first chamber 101. The fan assembly 40 includes a volute structure 401 arranged in the second chamber 102 and a wind wheel 402 arranged in the volute structure 401. The straightening member 50 is arranged in the shell 10 and is located between the heat exchanger 30 and the wind wheel 402. Among them, the middle partition 20 is provided with an air outlet 201 connecting the first chamber 101 and the volute structure 401. Along the air outlet direction, the projection of the straightening member 50 on the shell 10 at least partially overlaps with the projection of the air outlet 201 on the shell 10.

[0042] The heat exchanger 30 may be an evaporator.

[0043] Since the middle partition 20 is arranged in the shell 10 to form the first chamber 101 and the second chamber 102, the middle partition 20 can be supported by the shell 10. Since the heat exchanger 30 is arranged in the first chamber 101, the fan assembly 40 includes a volute structure 401 arranged in the second chamber 102 and a wind wheel 402 arranged in the volute structure 401. The middle partition 20 is provided with an air outlet 201 connecting the first chamber 101 and the volute structure 401. Therefore, when the wind wheel 402 rotates, the air flow in the volute structure 401 enters the first chamber 101 through the air outlet 201, so that the air flow exchanges heat with the heat exchanger 30 to achieve cooling or heating of the air conditioner. Since the rectifying member 50 is arranged in the shell 10 and is located between the heat exchanger 30 and the wind wheel 402, it rectifying along the air outlet direction. The projection of the component 50 on the shell 10 at least partially overlaps with the projection of the air outlet 201 on the shell 10. Therefore, in the process of the air flow flowing from the volute structure 40 through the air outlet 201 to the heat exchanger 30, the straightening component 50 can change the direction of the air flow passing through the straightening component 50 and reduce the air flow velocity of the air flow passing through the straightening component 50 to reduce the turbulence and eddy current of the air flow. The air flow with changed direction and reduced velocity can pass through the heat exchanger 30 smoothly, thereby reducing the impact and excitation vibration on the fins of the heat exchanger 30, which can directly reduce the mechanical noise generated thereby, improve the operating quietness of the air conditioner, and ensure the user experience. Moreover, the air flow can be evenly and stably contacted with the surface of the heat exchanger 30, thereby more effectively transferring heat and improving the heat exchange efficiency.

[0044] Figure 5 for Figure 4The first layout view of the fairing. Figure 5 In some embodiments, in order to change the direction of the airflow passing through the fairing 50 and reduce the airflow velocity passing through the fairing 50, the air outlet 201 has a first surface 2011 and a second surface 2012 connected to the first surface 2011 at an angle. Along the air outlet direction, the first surface 2011 has a first projection on the shell 10, the second surface 2012 has a second projection on the shell 10, and the fairing 50 has a third projection on the shell 10. Among them, the third projection can be connected with the first projection and the second projection, that is, the airflow passing through the air outlet 201 will inevitably pass through the straightening component 50, so that the straightening component 50 can more effectively guide the airflow blown out from the wind wheel 402, and ensure that when the airflow passes through the air outlet 201, the straightening component 50 can guide the airflow to flow in a predetermined direction and path. At the same time, it also reduces the airflow velocity to reduce the turbulence and eddy current of the airflow, so that the airflow passing through the air outlet 201 is evenly distributed before reaching the heat exchanger 30, and the airflow becomes smooth. The uniform and smooth airflow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the airflow, thereby improving the heat exchange efficiency.

[0045] Combine Figure 5 In some embodiments, to change the direction of airflow passing through the straightening element 50 and reduce the velocity of airflow passing through the straightening element 50, the straightening element 50 includes a first straightening portion 501 and a second straightening portion 502. Along the airflow direction, the first straightening portion 501 has a first sub-projection on the housing 10, and the second straightening portion 502 has a second sub-projection on the housing 10. The first sub-projection is connected to the first projection, and the second sub-projection is connected to the second projection.

[0046] In some embodiments, in the process of the air flow in the volute structure 40 reaching the heat exchanger 30, the air flow will inevitably pass through the first surface 2011 of the air outlet 201. The first rectifying portion 501 can guide the air flow to change the direction of the air flow passing through the first rectifying portion 501 and reduce the air flow velocity passing through the first rectifying portion 501, so as to reduce the turbulence and eddy of the air flow, so that the air flow passing through the air outlet 201 is evenly distributed before reaching the heat exchanger 30, and the air flow becomes smooth. The uniform and smooth air flow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the air flow, thereby improving the heat exchange efficiency.

[0047] In some embodiments, in the process of the air flow in the volute structure 40 reaching the heat exchanger 30, the air flow will inevitably pass through the second surface 2012 of the air outlet 201. The second rectifying portion 502 can guide the air flow to change the direction of the air flow passing through the second rectifying portion 502 and reduce the air flow velocity passing through the second rectifying portion 502, so as to reduce the turbulence and eddy of the air flow, so that the air flow passing through the air outlet 201 is evenly distributed before reaching the heat exchanger 30, and the air flow becomes smooth. The uniform and smooth air flow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the air flow, thereby improving the heat exchange efficiency.

[0048] Combine Figure 5 In some embodiments, the number of the first rectifying parts 501 can be multiple, and the multiple first rectifying parts 501 are arranged in parallel and spaced apart, and a rectifying channel is formed between every two adjacent first rectifying parts 501, so that the airflow can enter the first chamber 101 through the rectifying channel.

[0049] In some embodiments, there are two second surfaces 2012, each located on either side of the first surface 2011. The angle between the second surface 2012 and the first surface 2011 can be acute, right, or obtuse. When the second surface 2012 and the first surface 2011 are perpendicular, the perpendicular relationship between the second surface 2012 and the first surface 2011 is not absolutely perpendicular in a geometric sense; the angle between the second surface 2012 and the first surface 2011 can be within the range of 90±3°.

[0050] In some embodiments, the first surface 2011 is arc-shaped, which can smoothly guide the airflow through the air outlet 201, reduce the resistance and turbulence generated when the airflow turns or changes direction, and ensure the area of the air outlet 201 to ensure the air volume.

[0051] When there are multiple air outlets 201, the airflow between two adjacent air outlets 201 will cross-interfere. Figure 5 In some embodiments, in order to reduce the possibility of cross-interference between the airflows of each two adjacent air outlets 201, when the number of air outlets 201 is multiple, the rectifying member 50 in one of the two adjacent air outlets 201 is set close to the other air outlet 201. The rectifying member 50 can effectively control the direction of the airflow outflowing from the air outlet 201 to reduce the cross-interference of the airflow between the two adjacent air outlets 201, and ensure that the airflow of each air outlet 201 can flow according to the predetermined path, thereby improving the overall airflow guidance.

[0052] In some embodiments, the straightening member 50 in one of the two adjacent air outlets 201 is arranged close to the other air outlet 201, that is, the middle area of the air outlet 201 may not have the straightening member 50, reducing the air volume loss caused by the obstruction of the straightening member 50 to ensure the air outlet volume.

[0053] In some embodiments, the air outlet 201 has a first surface 2011 and two second surfaces 2012 respectively located on both sides of the first surface 2011, the two second surfaces 2012 include a first sub-surface and a second sub-surface, the first sub-surface is located between the second sub-surface and the adjacent air outlet 201, and the straightening member 50 is closer to the first sub-surface than the second sub-surface. The straightening member 50 can effectively control the direction of the airflow out of the air outlet 201 to reduce the cross-interference of the airflow between the two adjacent air outlets 201, and ensure that the airflow of each air outlet 201 can flow according to the predetermined path, thereby improving the overall airflow guidance.

[0054] Figure 6 for Figure 4 The second layout view of the fairing. Figure 6 Of course, in some other embodiments, part of the rectifying member 50 may be closer to the second sub-surface than the first sub-surface, and the rectifying member 50 may effectively control the direction of the airflow outflowing from the air outlet 201 to reduce the cross-interference of the airflow between the two adjacent air outlets 201, and ensure that the airflow of each air outlet 201 can flow according to the predetermined path, thereby improving the overall airflow guidance. Another part of the rectifying member 50 may be closer to the second sub-surface than the first sub-surface, and the wind at the edge of the air outlet 201 may be rectified to change the direction of the airflow passing through the rectifying member 50 and reduce the airflow velocity passing through the rectifying member 50, thereby reducing the turbulence and eddy of the airflow. The airflow with changed direction and reduced velocity can pass through the heat exchanger 30 smoothly, thereby reducing the impact and excitation vibration on the fins of the heat exchanger 30.

[0055] Combine Figure 4 、 Figure 5 and Figure 6In some embodiments, in order to change the direction of the airflow passing through the fairing 50 and reduce the flow rate of the airflow passing through the fairing 50, the fairing 50 is connected to the middle partition 20 and is at least partially located in the air outlet 201. When the wind wheel 402 rotates, the airflow in the volute structure 401 enters the first chamber 101 through the air outlet 201, so that the airflow exchanges heat with the heat exchanger 30 to achieve cooling or heating of the air conditioner. Since the fairing 50 is arranged in the shell 10 and is located between the heat exchanger 30 and the wind wheel 402, along the air outlet direction, the fairing 50 at least partially overlaps with the air outlet 201. Therefore, in the air When the air flows through the air outlet 201, the rectifying component 50 can change the direction of the air flow passing through the rectifying component 50 and reduce the air flow velocity of the air flow passing through the rectifying component 50 to reduce the turbulence and eddy current of the air flow. The air flow with changed direction and reduced velocity can pass through the heat exchanger 30 smoothly, thereby reducing the impact and excitation vibration on the fins of the heat exchanger 30, which can directly reduce the mechanical noise generated thereby, improve the quietness of the operation of the air conditioner, and ensure the user's experience. Moreover, the air flow can be in uniform and stable contact with the surface of the heat exchanger 30, thereby more effectively transferring heat and improving the heat exchange efficiency.

[0056] Combine Figure 5 and Figure 6 In some embodiments, to change the direction of airflow passing through the fairing 50 and reduce the airflow velocity, the air outlet 201 includes a first surface 2011 and a second surface 2012 connected to the first surface 2011 at an angle. The fairing 50 includes a first fairing portion 501 and a second fairing portion 502. The first fairing portion 501 is connected to the first surface 2011. The second fairing portion 502 is connected to the second surface 2012. The number of first fairing portions 501 can be multiple, and the multiple first fairing portions 501 are arranged in parallel and spaced apart.

[0057] In some embodiments, in the process of the air flow in the volute structure 40 entering the air port 201 and entering the first chamber 101, the air flow will inevitably pass through the first surface 2011 of the air port 201. The first rectifying portion 501 can guide the air flow to change the direction of the air flow passing through the first rectifying portion 501 and reduce the air flow velocity passing through the first rectifying portion 501, so as to reduce the turbulence and eddy of the air flow, so that the air flow passing through the air port 201 is evenly distributed before reaching the heat exchanger 30, and the air flow becomes smooth. The uniform and smooth air flow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the air flow, thereby improving the heat exchange efficiency.

[0058] In some embodiments, in the process of the air flow in the volute structure 40 reaching the second surface 2012 of the air outlet 201, the air flow will inevitably pass through the second surface 2012 of the air outlet 201. The second rectifying portion 502 can guide the air flow to change the direction of the air flow passing through the second rectifying portion 502 and reduce the flow rate of the air flow passing through the second rectifying portion 502, so as to reduce the turbulence and eddy current of the air flow, so that the air flow passing through the air outlet 201 is evenly distributed before reaching the heat exchanger 30, and the air flow becomes smooth. The uniform and smooth air flow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the air flow, thereby improving the heat exchange efficiency.

[0059] In some embodiments, in order to ensure the stability of the connection between the rectifier 50 and the middle partition 10, the rectifier 50 and the middle partition 10 can be integrally formed. The integrally formed design can eliminate the need for additional connectors or interfaces between the rectifier 50 and the middle partition 10. The rectifier 50 and the middle partition 10 can form an integral structure together with the middle partition 10, which has good strength and rigidity, reduces failures caused by loose or broken connections, and ensures the reliability of the connection between the rectifier 50 and the middle partition 10. Moreover, during the manufacturing process, the molding of the rectifier 50 and the middle partition 10 can be completed at one time without the need for additional connection steps. The manufacturing process of the rectifier 50 and the middle partition 10 can be simplified, production efficiency can be improved, and manufacturing costs can be reduced. At the same time, the position of the rectifier 50 on the middle partition 10 can be accurately fixed, which can eliminate installation errors that may occur in the subsequent assembly process, ensure precise matching between components, and thus improve the overall performance and reliability of the product.

[0060] Figure 7 for Figure 4 A schematic diagram of the third arrangement of the middle fairing; Figure 8 for Figure 4 The fourth arrangement diagram of the middle rectifier. Figure 3 、 Figure 7 and Figure 8In some embodiments, to change the direction of airflow passing through the fairing 50 and reduce the velocity of airflow passing through the fairing 50, the volute structure 401 includes a first volute 4011, a connector 4012, and a second volute 4013. The first volute 4011 is connected to the intermediate partition 20. The connector 4012 is located within the second chamber 102 and is connected to the intermediate partition 20. The second volute 4013 is connected to the first volute 4011 and the connector 4012 to form a receiving chamber, in which the impeller 402 is located. The fairing 50 is connected to at least one of the connector 4012, the first volute 4011, and the second volute 4013, and the air outlet 201 connects the receiving chamber and the first chamber 101. When the air conditioner is in use, the first volute 4011 is located above the second volute 4012.

[0061] In some embodiments, in the process of air flow flowing from the accommodating chamber to the air outlet 201, the air flow will inevitably pass through the first volute 4011, the connecting piece 4012 and the second volute 4013. The straightening piece 50 is connected to at least one of the connecting piece 4012, the first volute 4011 and the second volute 4013. The straightening piece 50 can change the direction of the air flow passing through the straightening piece 50 and reduce the air flow velocity of the air flow passing through the straightening piece 50 to reduce the turbulence and eddy current of the air flow. The air flow with changed direction and reduced velocity can pass through the heat exchanger 30 smoothly, thereby reducing the impact and excitation vibration on the fins of the heat exchanger 30, which can directly reduce the mechanical noise generated thereby, improve the operating quietness of the air conditioner, and ensure the user experience. Moreover, the air flow can be evenly and stably in contact with the surface of the heat exchanger 30, thereby more effectively transferring heat and improving the heat exchange efficiency.

[0063] In some embodiments, the connector 4012 is connected to the edge of the air outlet 201. When the fairing 50 is connected to the connector 4012, the fairing 50 is close to the air outlet 201. When the fairing 50 is connected to the first volute 4011, the fairing 50 is located at the end of the first volute 4011 facing the air outlet 201. When the fairing 50 is connected to the second volute 4013, the fairing 50 is located at the end of the second volute 4013 facing the air outlet 201.

[0065] In some embodiments, when the fairing 50 is connected only to the connector 4012, the fairing 50 may be integrally formed with the connector 4012.

When the fairing 50 is connected to the connector 4012 and the second volute 4013, a portion of the fairing 50 may be integrally formed with the connector 4012, and another portion may be integrally formed with the second volute 4013. When the fairing 50 is connected to the first volute 4011 and the second volute 4013, part of the fairing 50 can be integrally formed with the first volute 4011, and another part can be integrally formed with the second volute 4013. When the fairing 50 is connected to the connecting member 4012, the first volute 4011, and the second volute 4013, part of the fairing 50 can be integrally formed with the connecting member 4012 and the first volute 4011, and another part can be integrally formed with the second volute 4013.

[0066] In some embodiments, to change the direction of airflow passing through the fairing 50 and reduce the airflow velocity, the fairing 50 includes a first fairing portion 501 and a second fairing portion 502. The first fairing portion 501 is connected to at least one of the connector 4012, the first volute 4011, and the second volute 4013. The second fairing portion 502 is connected to the first volute 4011. The second connecting portion 502 can be connected to a side of the first volute 4011.

[0067] In some embodiments, in the process of airflow flowing from the accommodating chamber to the air outlet 201, the airflow will inevitably pass through the connecting piece 4012, the first volute 4011 and the second volute 4013. The first rectifying part 501 can guide the airflow to change the direction of the airflow passing through the first rectifying part 501 and reduce the airflow velocity passing through the first rectifying part 501, so as to reduce the turbulence and eddy of the airflow, so that the airflow passing through the air outlet 201 is evenly distributed before reaching the heat exchanger 30, and the airflow becomes smooth. The uniform and smooth airflow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the airflow, thereby improving the heat exchange efficiency.

[0068] In some embodiments, in the process of airflow flowing from the accommodating chamber to the air outlet 201, the airflow will inevitably pass through the first volute 4011, and the second rectifying part 502 can guide the airflow to change the direction of the airflow passing through the second rectifying part 502 and reduce the airflow velocity passing through the second rectifying part 502, so as to reduce the turbulence and eddy of the airflow, so that the airflow passing through the air outlet 201 is evenly distributed before reaching the heat exchanger 30, and the airflow becomes smooth. The uniform and smooth airflow reduces the impact and excitation vibration on the fins of the heat exchanger 30, thereby reducing the mechanical noise generated thereby. Moreover, the heat on the fins of the heat exchanger 30 can be more evenly transferred to the airflow, thereby improving the heat exchange efficiency.

[0069] In some embodiments, in order to reduce costs, the first volute 4011, the connector 4012 and the middle partition 20 are integrally formed, and the first volute 4011 and the connector 4012 are integrated on the middle partition 10, that is, the middle partition 10 has a first volute mounting position and a first connector mounting position, and the middle partition 10 is installed in the housing of the air conditioner. The first volute 4011 and the connector 4012 can be assembled through an middle partition 10, which can reduce the number of parts and reduce the cost of the entire process of manufacturing, transportation, storage, and production. Moreover, only the middle partition 10 needs to be installed in the housing of the air conditioner to realize the assembly of the first volute 4011 and the connector 4012 in the housing of the air conditioner, without It is necessary to install the first volute 4011 and the connecting piece 4012 in the shell of the air conditioner, which reduces the assembly action and improves the production efficiency. The positions of the first volute 4011 and the connecting piece 4012 on the middle partition 10 are determined, which reduces the assembly error caused by the assembly of multiple parts and improves the assembly accuracy. When the second volute 30 is connected with the first volute 4011 and the connecting piece 4012, the stability of the connection between the second volute 30 and the first volute 4011 and the connecting piece 4012 is also guaranteed. At the same time, the middle partition 10, the first volute 4011 and the connecting piece 4012 exist as a whole. During maintenance, only the middle partition 10 needs to be replaced, and there is no need to stock multiple spare parts separately, which reduces inventory costs, simplifies the spare parts management process, and reduces the difficulty of maintenance.

[0070] Combine Figure 3 In some embodiments, as air flows from the accommodating chamber to the air outlet 201, the volute structure 401 includes a first volute 4011, a connector 4012, and a second volute 4013. The first volute 4011 is connected to the intermediate partition 20. The connector 4012 is located within the second chamber 102 and is connected to the intermediate partition 20. The second volute 4013 is connected to the first volute 4011 and the connector 4012 to form an accommodating chamber, in which the impeller 402 is disposed. The fairing 50 is disposed on the intermediate partition 20, the connector 4012, and the second volute 4013.

[0071] In some embodiments, in the process of airflow flowing from the volute structure 40 through the air outlet 201 to the heat exchanger 30, the airflow will inevitably flow through the second volute 4013, the connecting piece 4012 and the air outlet 201. The straightener 50 can change the direction of the airflow passing through the straightener 50 and reduce the airflow velocity of the airflow passing through the straightener 50 to reduce the turbulence and eddy current of the airflow. The airflow with changed direction and reduced velocity can pass through the heat exchanger 30 smoothly, thereby reducing the impact and excitation vibration on the fins of the heat exchanger 30, which can directly reduce the mechanical noise generated thereby, improve the operating quietness of the air conditioner, and ensure the user experience. Moreover, the airflow can be evenly and stably contacted with the surface of the heat exchanger 30, thereby more effectively transferring heat and improving the heat exchange efficiency.

[0072] Combine Figure 3 In some embodiments, the fairing 50 can be provided at least one of the middle partition 20, the first volute 4011, the connecting piece 4012 and the second volute 4013, which can change the direction of the airflow passing through the fairing 50 and reduce the flow rate of the airflow passing through the fairing 50.

The fairing 50 may be provided on the middle diaphragm 20, the connecting member 4012, and the second volute 4013.

[0074] In some embodiments, in order to reduce the flow resistance of the airflow, the straightening member 50 has an inclined guide surface, which can reduce the contact area between the airflow and the straightening member 50, thereby reducing the resistance encountered by the airflow during the flow process to ensure the flow rate of the airflow. Moreover, the inclined guide surface can guide the airflow to flow in a predetermined direction and path, reduce the turbulence and eddy current phenomenon of the airflow during the flow process, reduce the energy loss of the airflow, and improve the flow efficiency.

[0075] In some embodiments, in order to ensure the air volume, the length of the rectifying member 50 can be 3 mm to 30 mm. Under the condition that the rectifying member 50 can change the direction of the airflow passing through the rectifying member 50 and reduce the airflow velocity passing through the rectifying member 50, the area of the rectifying member 50 overlapping at least partially with the air outlet 201 can be reduced along the air outlet direction to reduce the obstruction of the airflow, so that the airflow can pass through the air outlet smoothly, thereby ensuring the air volume.
