Description

Technical Field

[0001] The present application relates to the technical field of air conditioning devices, for example, to an air conditioner. Background Art

[0002] With the popularization of air conditioning and the promotion of health concepts, users have higher and higher requirements for the comfort of wall-mounted air conditioners. They hope that in heating mode, hot air will be blown to the ground to achieve carpet-style air supply. Because in carpet-style air supply, the density of hot air is relatively small compared to cold air, and the hot air blown to the ground will continue to float up, quickly raising the room temperature, instead of blowing the hot air directly to the upper part of the room, so that the hot air will gather in the upper part and be difficult to sink, resulting in an uncomfortable feeling of warm head and cold feet; they hope that in cooling mode, cold air will be blown to the upper part of the room to achieve bathing-style air supply. Because in bathing-style air supply, the cold air blown to the upper part of the room will continue to sink, quickly lowering the room temperature, instead of blowing the cold air directly to the ground, so that the cold air will gather in the lower part of the room, causing the phenomenon of cold feet and hot head, and directly blowing people to cause physical discomfort.

[0003] Currently, some air conditioners control the upward or downward flow of air by adding a baffle at the air outlet. During the implementation of the embodiments of the present disclosure, it was found that the related art has at least the following problems: switching the air supply direction by using a baffle creates significant wind resistance to the airflow and results in a high level of air outlet noise. Summary of the Invention

[0004] In order to provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. The summary is not an extensive review, nor is it intended to identify key / critical elements or delineate the scope of protection of these embodiments, but rather serves as a prelude to the detailed description that follows.

[0005] An embodiment of the present disclosure provides an air conditioner to solve the problem of high wind resistance and noise in the air outlet of an air conditioner equipped with a deflector.

[0006] In some embodiments, the air conditioner includes a duct outer shell having an air inlet and an air outlet, and also includes: a duct inner shell, arranged inside the duct outer shell, including an air flow inlet and an air flow outlet, the air flow inlet faces the air inlet, and the air flow outlet faces the air outlet; an air supply mechanism, arranged at the air flow inlet; a driving mechanism, connected to the duct inner shell, driving the duct inner shell to rotate around the air supply mechanism so that the air flow outlet corresponds to different positions of the air outlet.

[0007] The air conditioner provided by the embodiment of the present disclosure can achieve the following technical effects: the air supply mechanism generates an air flow that flows through the air flow inlet of the air duct inner shell to the air flow outlet, and the driving mechanism drives the air duct inner shell to rotate around the air supply mechanism, so that the air flow outlet can correspond to different positions of the air outlet, thereby achieving the air supply air flow of the air conditioner to different directions. The direction of the air flow is changed by rotating the air duct inner shell, and the flow direction of the air flow in the air duct inner shell does not change suddenly, and smooth air supply can be maintained. Compared with using a guide plate to change the air outlet direction, the wind resistance and air outlet noise are reduced.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present disclosure can be combined with each other.

[0024] Combine Figure 1 、2 As shown in Figure 3, an embodiment of the present disclosure provides an air conditioner, comprising an air duct outer shell 20 having an air inlet and an air outlet 21, and further comprising: an air duct inner shell 30, an air supply mechanism 40, and a drive mechanism 50. The air duct inner shell 30 is disposed within the air duct outer shell 20 and comprises an air flow inlet and an air flow outlet 31, with the air flow inlet facing the air inlet and the air flow outlet 31 facing the air outlet 21; the air supply mechanism 40 is disposed at the air flow inlet; and the drive mechanism 50 is connected to the air duct inner shell 30 and drives the air duct inner shell 30 to rotate around the air supply mechanism 40 so that the air flow outlet 31 corresponds to different positions of the air outlet 21.

[0025] The air supply mechanism 40 generates an air flow that flows through the air flow inlet of the air duct inner shell 30 to the air flow outlet 31. The driving mechanism 50 drives the air duct inner shell 30 to rotate around the air supply mechanism 40, which can make the air flow outlet 31 correspond to different positions of the air outlet 21, thereby achieving the purpose of blowing the air supply airflow of the air conditioner to different directions. The rotation of the air duct inner shell 30 realizes the change of the air flow direction, and the flow direction of the air flow in the air duct inner shell 30 changes naturally instead of suddenly, which can maintain smooth air supply. Compared with the use of a guide plate to forcibly change the air outlet direction, the wind resistance and air outlet noise are reduced. Optionally, the air supply mechanism 40 is entirely located in the air flow inlet, so that the air can be driven from the air flow inlet into the air duct inner shell 30 and flow toward the air flow outlet 31. Optionally, the air supply mechanism 40 is partially located in the air flow inlet. In this way, more air flow outside the air duct inner shell 30 can be guided into the air flow inlet.

[0026] The air duct housing 20 is disposed outside the air duct inner housing 30 and has an air inlet and an air outlet 21. Airflow can sequentially pass through the air inlet, airflow inlet, airflow outlet 31, and air outlet 21. The air duct housing 20 can be fixedly disposed within the air conditioner. Under the guidance of the air supply mechanism 40, the airflow entering the air conditioner enters the air duct housing 20 and the air duct inner housing 30 for airflow regulation. Optionally, the air conditioner is an on-hook unit. Through the interaction of the air supply mechanism 40, the drive mechanism 50, the air duct housing 20, and the air duct inner housing 30, the on-hook unit can supply air upward or downward. Optionally, the air conditioner includes a housing, the housing having an air inlet. The air duct housing 20 is disposed at the lower portion of the housing and communicates with the interior of the housing via the air inlet. Airflow enters the interior of the housing through the air inlet and flows into the air duct housing 20 through the air inlet.

[0027] Optionally, the drive mechanism 50 drives the air duct inner shell 30 to rotate around the air supply mechanism 40, and the airflow outlet 31 can move between the upper and lower parts of the air outlet 21, corresponding to the upper or lower part of the air outlet 21. When the airflow outlet 31 corresponds to the upper part of the air outlet 21, the airflow blows upward after passing through the airflow outlet 31, and conversely, the airflow blows downward after passing through the airflow outlet 31. In this way, when the air conditioner is in cooling mode, the airflow outlet 31 can be made to correspond to the upper part of the air outlet 21, and the cold air blows to the upper part of the room and continuously sinks, achieving a shower-style air supply. Shower-style air supply can quickly lower the room temperature. Compared with blowing cold air directly to the ground, it prevents the phenomenon of cold feet and hot head, and avoids direct blowing that causes physical discomfort. When the air conditioner is in heating mode, the airflow outlet 31 is made to correspond to the lower part of the air outlet 21, and the hot air blows to the ground to achieve a carpet-style air supply. Since the hot air has a lower density than the cold air, the hot air continuously rises, quickly raising the room temperature. Compared with blowing hot air directly to the upper part of the room, the heat gathers in the upper part and is difficult to sink, which can avoid the uncomfortable feeling of warm head and cold feet.

[0028] Combine Figure 2 、 3 As shown, in some embodiments, the air duct inner shell 30 includes an arcuate portion 301 and a volute tongue portion 302. The arcuate portion 301 is disposed toward the rear side of the air duct outer shell 20; the volute tongue portion 302 is connected to the arcuate portion and is closer to the front side of the air duct outer shell 20 than the arcuate portion 301.

[0029] The front side refers to the side of the air conditioner facing the user, and the rear side refers to the side of the air conditioner facing away from the user. The air duct inner shell 30 formed by the arc portion 301 and the volute tongue portion 302 enables the air flow inlet of the air duct inner shell 30 to be designed to be larger, fully collecting the air flow thrown out from the air supply mechanism 40. The air duct inner shell 30 formed by the arc portion 301 and the volute tongue portion 302 is similar to a volute shape, which is also beneficial to the air supply of the air conditioner. In addition, in the air conditioner wall unit, the air outlet 21 is located at the lower part of the air duct outer shell 20 and the front part near the lower part. The arc portion 301 of the air duct inner shell 30 is arranged toward the rear side of the air duct outer shell 20. When the air duct inner shell 30 rotates, the moving trajectory of the arc portion 301 occupies a smaller space, which facilitates the rotation of the air duct inner shell 30 in the air duct outer shell 20. The volute tongue portion 302 is closer to the front side of the air duct housing 20 than the arc portion 301 . The bent shape of the volute tongue portion 302 cooperates with the arc portion 301 to form a channel that is conducive to airflow transmission.

[0030] Optionally, the rear side of the air duct outer shell 20 is curved. In this way, the air duct outer shell 20 and the curved portion 301 of the air duct inner shell 30 can be adapted to each other. When the air duct inner shell 30 rotates to approach the rear side of the air duct outer shell 20, the curved portion 301 can fit with the rear side of the air duct outer shell 20, which can also make the air duct inner shell 30 more stable.

[0031] Combine Figure 2 、3 As shown, in some embodiments, a tongue support 303 is provided on the outer surface of the tongue portion 302 to prevent the tongue portion 302 from deforming. In order to facilitate the conveyance of airflow, the tongue has a certain bending angle, that is, one side wall of the tongue is bent outward relative to the other side wall. When the angle is less than 90° (that is, the angle between the two side walls that are bent is less than 90°), the tongue is easily deformed when subjected to external force, resulting in a smaller angle. When the air duct inner shell 30 is delivering air, the impact force generated by the airflow is likely to cause the tongue to further bend and deform. The tongue support 303 is provided to support the tongue on its outer surface, thereby avoiding a reduction in the air supply effect due to deformation of the tongue.

[0032] Optionally, the volute tongue support member 303 includes a first plate member and a second plate member connected to each other. The second plate member is bent relative to the first plate member toward the outside of the volute tongue portion 302. The angle between the first plate member and the second plate member is greater than the angle of the volute tongue portion 302. One side of the first plate member is connected to the first sidewall of the volute tongue portion 302, and part or all of the second plate member is connected to the second sidewall of the volute tongue portion 302. The support provided by the first and second plates to the first and second sidewalls of the volute tongue portion 302 ensures that the volute tongue portion 302 remains firm and stable and is not susceptible to deformation.

[0033] Combine Figure 2 、 3 As shown in FIG4 , in some embodiments, the volute tongue portion 302 includes a first sidewall and a second sidewall. The second sidewall is connected to the first sidewall and is bent relative to the first sidewall. The second sidewall of the volute tongue portion 302 is bent relative to the first sidewall, allowing the volute tongue portion 302 and the arc-shaped portion 301 to form a shape similar to the volute air outlet duct, facilitating airflow guidance and discharge. A volute tongue support 303 can be provided on the outer surfaces of the first and second sidewalls to maintain the shape of the volute tongue portion 302. Optionally, a raised portion 22 shaped to match the volute tongue support 303 is provided on the upper side of the duct outer shell 20. Thus, when the duct inner shell 30 rotates to the position where the airflow outlet 31 corresponds to the upper portion of the air outlet 21, the volute tongue support 303 mates with the raised portion 22, providing a more secure fit between the volute tongue support 303 and the raised portion 22, preventing the duct inner shell 30 from shaking and maintaining stability in this position. Moreover, the contact between the volute tongue support 303 and the protrusion 22 can prevent part of the air flow in the air conditioner from leaking out from the gap between the volute tongue portion 302 and the air duct outer shell 20 without entering the air duct inner shell 30 .

[0034] Optionally, the second plate of the volute support extends toward the air outlet 21 and has a greater extension toward the air outlet 21 than the second sidewall of the volute tongue portion 302. In this way, the volute support can also provide a certain degree of airflow blocking. For example, when the airflow outlet 31 of the air duct inner casing 30 is oriented toward the lower portion of the air outlet 21, it can prevent some airflow from flowing toward the upper portion of the air outlet 21 upon exiting the airflow outlet 31.

[0035] Combine Figure 2 、 3 As shown in Figure 4, in some embodiments, the air conditioner further includes a partition 60, which is rotatably arranged on the inner surface of the air duct outer shell 20, and one side of the partition 60 is resting on the air flow inlet. The partition 60 is arranged on the inner surface of the air duct outer shell 20, one side is rotatably connected to the inner surface of the air duct outer shell 20, and the other side is resting on the air flow inlet, so that the resting side can move with the rotation of the air duct inner shell 30. The partition 60 is arranged in this way, which can block the gap between the air duct outer shell 20 and the air flow inlet, and prevent part of the air flow from not entering the air duct inner shell 30 and flowing directly out from the gap between the air duct outer shell 20 and the air flow inlet of the air duct inner shell 30, thereby affecting the air supply direction. When the air flow inlet corresponds to the upper part of the air outlet 21, the partition 60 is located in the space enclosed by the volute tongue support 303 and the air duct outer shell 20.

[0036] In some embodiments, the air supply mechanism 40 is a cross-flow fan, and the driving mechanism 50 drives the air duct inner shell 30 to rotate around the rotating shaft of the cross-flow fan. When the cross-flow fan rotates, the air flow enters the blade grid from the opening of the impeller, passes through the inside of the impeller, and is discharged from the blade grid on the other side. It is suitable to be set at the air flow inlet of the air duct inner shell 30. The air duct inner shell 30 is rotated around the rotating shaft of the cross-flow fan to facilitate the collection of the air flow discharged by the cross-flow fan, and can also achieve the adjustment of the air flow direction, making the air conditioner structure more compact and reasonable. Figure 1 、 2 As shown, the air conditioner optionally further includes a base 11, a heat exchanger 10, and end plates 12. The base 11 is disposed outside the air duct outer shell 20 and the air duct inner shell 30. The air supply mechanism 40 is disposed on the base 11 and penetrates the air duct inner shell 30. The heat exchanger 10 is disposed above the air supply mechanism 40. The end plates 12 are disposed at both ends of the heat exchanger 10. In this way, the base 11 and the end plates 12 can be fixed to the air conditioner housing, thereby fixing the cross-flow fan and the heat exchanger 10.

[0037] In some embodiments, the air duct inner casing 30 extends along the length of the air conditioner, and is provided with a cylindrical body 70 at one or both ends that communicates with the air duct inner casing 30. The drive mechanism 50 is connected to the cylindrical body 70 to drive the air duct inner casing 30 to rotate. The cylindrical body 70 is provided at one end of the air duct inner casing 30, and the drive mechanism 50 is connected to the cylindrical body 70. The drive mechanism 50 drives the cylindrical body 70 to rotate, thereby driving the air duct inner casing 30 to rotate. Because the air duct inner casing 30 is irregularly shaped, the drive mechanism 50 directly acts on the air duct inner casing 30, making it difficult to drive the air duct inner casing 30 to rotate. However, the cylindrical body 70 is a regularly shaped component, which facilitates the drive mechanism to interact with the cylindrical body 70 and drive the cylindrical body 70 to rotate. Optionally, the cylindrical body 70 is provided at one end of the air duct inner casing 30. By driving the cylindrical body 70 at one end through the drive mechanism 50, the air duct inner casing 30 can be driven to rotate. Optionally, cylindrical bodies 70 are provided at both ends of the air duct inner shell 30, and the drive mechanism 50 includes a first drive mechanism and a second drive mechanism, wherein the first drive mechanism drives the cylindrical body 70 at one end of the air duct inner shell 30, and the second drive mechanism drives the cylindrical body 70 at the other end of the air duct inner shell 30. In this way, the drive mechanism 50 drives the cylindrical bodies 70 at both ends of the air duct inner shell 30 to rotate, which can make the air duct inner shell 30 rotate more smoothly.

[0038] Combine Figure 5 As shown, in some embodiments, the outer surface of the cylindrical body 70 is provided with a tooth portion 701, and the driving mechanism 50 is connected to the tooth portion 701. The cylindrical body 70 is provided with the tooth portion 701 on the outer surface to facilitate the interaction between the driving mechanism 50 and the cylindrical body 70. The driving mechanism 50 is connected to the tooth portion 701, and the tooth portion 701 can be moved, thereby driving the cylindrical body 70 to rotate. Optionally, a local area of ​​the outer periphery of the cylindrical body 70 is provided with the tooth portion 701. The driving mechanism 50 only needs to rotate the cylindrical body 70 back and forth within a certain angle range. The tooth portion 701 can be only provided along the local outer periphery, and the other areas of the cylindrical body 70 can be smooth surfaces. In this way, other parts can also be provided in other areas of the cylindrical body 70. Optionally, the tooth portion 701 is arranged at the bottom or oblique lower part of the cylindrical body 70. In this way, the gravity of the cylindrical body 70 itself cooperates with the shape of the tooth portion 701, making the force between the driving mechanism 50 and the tooth portion 701 greater, which is conducive to the smooth rotation of the cylindrical body 70. Furthermore, arranging the driving mechanism 50 obliquely below the cylindrical body 70 can also avoid occupying the space above the cylindrical body 70. The space above the cylindrical body 70 is left vacant for components such as the heat exchanger 10, and also avoids blocking the airflow.

[0039] In some embodiments, the drive mechanism 50 includes a motor 501 and a gear 502, and the gear 502 is sleeved on the outside of the drive shaft of the motor 501 and meshed with the tooth portion 701. The drive shaft of the motor 501 rotates, driving the gear 502 to rotate, and the gear 502 meshes with the tooth portion 701, which can drive the tooth portion 701 to move, thereby rotating the cylindrical body 70. Optionally, the air conditioner also includes a controller, which is connected to the drive mechanism 50. When it is necessary to make the air flow outlet 31 correspond to the upper part of the air outlet 21, the controller controls the drive shaft of the motor 501 to rotate forward, so that the air duct inner shell 30 rotates upward; when it is necessary to make the air flow outlet 31 correspond to the lower part of the air outlet 21, the controller controls the drive shaft of the motor 501 to rotate in the opposite direction, so that the air duct inner shell 30 rotates downward.

[0040] Combine Figure 2 、 3 As shown in Figure 6, in some embodiments, the air conditioner further comprises a pressing structure 80. The pressing structure 80 is provided on the air duct outer shell 20, in contact with the outer surface of the cylindrical body 70, and opposite to the driving mechanism 50. The pressing structure 80 contacts the outer surface of the cylindrical body 70, compresses the cylindrical body 70, and prevents the cylindrical body 70 from vibrating when the driving mechanism 50 drives the cylindrical body 70 to rotate, so that the air duct inner shell 30 rotates more smoothly. The driving mechanism 50 is connected to the cylindrical body 70, and by driving the cylindrical body 70 to rotate, the air duct inner shell 30 is driven to rotate. During the rotation of the air duct inner shell 30, the driving mechanism 50 interacts with the air duct inner shell 30, which may cause uneven force on the air duct inner shell 30, thereby generating vibration. At this time, by providing the pressing structure 80, the rolling assembly 801 of the pressing structure 80 contacts the cylindrical body 70, compresses the cylindrical body 70, and makes the cylindrical body 70 balanced in force and rotates smoothly. In order to make the forces generated by the pressing structure 80 and the driving mechanism 50 more balanced, the connection between the driving mechanism 50 and the cylindrical body 70 is positioned opposite to the rolling assembly 801. In this way, the cylindrical body 70 is subjected to more balanced forces and rotates more smoothly.

[0041] Combine Figure 2 、 3As shown in Figure 6, in some embodiments, the compression structure 80 includes: a rolling assembly 801, a cover 802, and a connector 803. The rolling assembly 801 is in contact with the outer surface of the cylindrical body 70, and the cover 802 is arranged on the outer side of the rolling assembly 801; the connector 803 is connected to the cover 802 at one end and to the air duct housing 20 at the other end. The cover 802 is arranged on the outer side of the rolling assembly 801 to prevent the rolling assembly 801 from being scratched by other components in the air conditioner and protect the rolling assembly 801. It can also prevent other debris from falling onto the rolling assembly 801 and the cylindrical body 70, affecting the mutual cooperation between the rolling assembly 801 and the cylindrical body 70. Optionally, the rolling assembly 801 includes one or more rollers, the surface of the rollers being in contact with the outer surface of the cylindrical body 70. The rollers are used to compress the cylindrical body 70 and keep the cylindrical body 70 rotating smoothly.

[0042] Optionally, the cover 802 is provided with an opening through which the rolling assembly 801 is exposed, so that the rolling assembly 801 can contact the surface of the cylindrical body 70. This ensures that the rolling assembly 801 can exert a compressive force on the cylindrical body 70. The connecting member 803 connects the cover 802 to the air duct housing 20, thereby securing the cover 802. Optionally, the connecting member 803 is rod-shaped. The rod-shaped connecting member 803 has two ends, which can connect the air duct housing 20 and the cover 802. Optionally, the other end of the connecting member 803 is connected to the outer wall of the air duct housing 20. On the basis of achieving the connection between the cover 802 and the air duct housing 20, the connection between the connecting member 803 and the air duct housing 20 prevents interference with the rotation trajectory of the cylindrical body 70. Optionally, one or both ends of the air duct housing 20 are provided with end caps. The cover 802 is connected to the end caps via screws 805.

[0043] Combine Figure 2 、 3 As shown in Figure 6, in some embodiments, the compression structure 80 further includes a support column 804, which is disposed in the housing 802 and can support the rolling assembly 801. The support column 804 can support the rolling assembly 801 to roll stably. Optionally, the support column 804 is fixedly connected to the housing 802, and the support column 804 is rotatably connected to the rolling assembly 801. In this way, the support column 804 can form a relatively stable support for the rolling assembly 801, and maintain stability when the rolling assembly 801 rotates. Optionally, the support column 804 is parallel to the central axis of the cylindrical body 70. In this way, it is convenient to support the rolling assembly 801.

[0044] Optionally, a support column 804 is positioned at the central axis of the roller and is rotatably connected to the roller. When the roller rotates, it pivots around the support column 804, providing more balanced support for the roller. Optionally, both ends of the support column 804 are connected to the housing 802. This provides a more secure and stable support column 804, preventing the roller from shifting due to the rotation of the cylindrical body 70, which could cause the support column 804 to skew or deform.
