Therefore, one objective of this utility model is to provide an air conditioner whose air guide plate can rotate in two different directions to open the air outlet. This makes the air guide plate more flexible in opening the air outlet and also allows for a wider range of rotation angles, making the adjustment of the air outlet direction more flexible. Furthermore, when heating, rotating the air guide plate upwards to open the air outlet helps to push the hot air downwards, improving the heating comfort of the air conditioner.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] The following is for reference. Figures 1-5 This invention describes an air conditioner 100 according to an embodiment of the present invention.

[0038] An air conditioner 100 according to an embodiment of the present utility model includes: a housing 10, a heat exchanger assembly, an air duct assembly, an air guide plate 30, and a drive mechanism 38.

[0039] For example, air conditioner 100 can be a split-type air conditioner 100, which includes an outdoor unit and an indoor unit. The indoor unit includes a casing 10, a heat exchanger assembly, an air duct assembly, an air guide plate 30, and a drive mechanism 38. When air conditioner 100 is a split-type air conditioner 100, it can be a split-type wall-mounted air conditioner 100.

[0040] Reference Figures 1-3 The casing 10 has an air inlet, an air outlet 12, and an air outlet duct 13. A heat exchanger assembly is disposed within the casing 10. An air duct assembly, including a fan, is also disposed within the casing 10. The air duct assembly can be located between the heat exchanger assembly and the air inlet, and is located upstream of the air outlet duct 13. A guide vane 30 is rotatably disposed at the air outlet 12 to open and close the air outlet 12. The rotation axis of the guide vane 30 extends in the left-right direction. The air inlet can be formed at the top of the casing 10, and the air outlet 12 can be formed at the lower front part of the casing 10.

[0041] When the air conditioner 100 is operating, its fan rotates, driving air through the air inlet into the casing 10. The airflow exchanges heat with the heat exchanger assembly. For example, when the air conditioner 100 is in heating mode, the airflow is heated by the heat exchanger assembly; when the air conditioner 100 is in cooling mode, the airflow is cooled by the heat exchanger assembly. After heat exchange, the airflow enters the air outlet duct 13 through the air duct assembly, and is then guided out of the room by the air guide plate 30 through the air outlet 12, thereby regulating the indoor air temperature. By extending the rotation axis of the air guide plate 30 of the air conditioner 100 in the left-right direction, the air guide plate 30 can guide the airflow upwards or downwards.

[0042] The drive mechanism 38 is mounted on the housing 10 and connected to the air guide plate 30. The drive mechanism 38 drives the air guide plate 30 to rotate in a first rotation direction to open the air outlet 12 and also in a second rotation direction, opposite to the first rotation direction. By enabling the drive mechanism 38 of the air conditioner 100 to drive the air guide plate 30 to rotate in both the first and second rotation directions (opposite to the first), the rotatable angle range of the air guide plate 30 of the air conditioner 100 is increased, and the adjustable airflow range of the air conditioner 100 is expanded. This makes the adjustment of the air outlet direction of the air guide plate 30 to the air outlet 12 more flexible, improving the user experience.

[0043] For example, the rotation axis of the air guide plate 30 extends in the left-right direction, one of the first rotation direction and the second rotation direction is clockwise, and the other of the first rotation direction and the second rotation direction is counterclockwise. That is, the air guide plate 30 of the air conditioner 100 can rotate upward and downward, so that the air guide plate 30 of the air conditioner 100 can guide the airflow in the direction of downward, forward or upward, thereby increasing the air supply adjustment range of the air conditioner 100 and improving the user experience.

[0044] For example, when cooling, the air guide plate 30 rotates downward to open and deliver air over a longer distance; when heating, the air guide plate 30 rotates upward to open and push the hot air downward, making the ambient temperature more uniform and improving the heating effect of the air conditioner 100.

[0045] According to the air conditioner 100 of this utility model embodiment, the air guide plate 30 of the air conditioner 100 can rotate in two different rotation directions to open the air outlet 12, making the air guide plate 30 more flexible in opening the air outlet 12, and also making the rotation angle range of the air guide plate 30 larger, so that the air guide plate 30 can adjust the air outlet direction of the air outlet 12 more flexibly; and when heating, the air guide plate 30 rotates upward to open the air outlet 12, which is conducive to the air guide plate 30 pressing the hot air downward, improving the heating comfort of the air conditioner 100; when cooling, the air guide plate 30 rotates downward to open the air outlet 12, which is also conducive to guiding the cold air upward. Thus, the air guide plate 30 of the air conditioner 100 has a better guiding effect on airflow during both heating and cooling.

[0046] According to some embodiments of this utility model, refer to Figures 1-3 The two ends of the air guide plate 30 in the width direction are the first width end 31 and the second width end 32, respectively, and the width direction of the air guide plate 30 is perpendicular to the extension direction of the rotation axis of the air guide plate 30.

[0047] The air guide plate 30 has a first position, a second position, and a third position. The first position is when the air guide plate 30 closes the air outlet 12. In the second position, the first wide end 31 is located inside the air outlet channel 13 and the second wide end 32 is located outside the housing 10. In the third position, the second wide end 32 is located inside the air outlet channel 13 and the first wide end 31 is located outside the housing 10. The air guide plate 30 is adapted to rotate from the first position to the second position along the first rotation direction and is adapted to rotate from the first position to the third position along the second rotation direction.

[0048] By enabling the air guide plate 30 to rotate from the first position to the second position along the first rotation direction and from the first position to the third position along the second rotation direction, the range of rotation angles of the air guide plate 30 can be increased, and the air conditioner 100 can more flexibly adjust the air outlet 12 air direction.

[0049] For example, when the air guide plate 30 is in the first position, the vertical direction of the air guide plate 30 is the width direction of the air guide plate 30, the lower end face of the air guide plate 30 is the first width end face 31, and the upper end face of the air guide plate 30 is the second width end face 32. When the air conditioner 100 is in cooling mode, the air guide plate 30 can rotate from the first position to the second position along the first rotation direction to guide the cold air upward; when the air conditioner 100 is in heating mode, the air guide plate 30 can...

[0050] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 An air outlet 12 is formed at the lower front part of the housing 10. The air outlet duct 13 has an upper sidewall 14 and a lower sidewall 15. In the second position, the air guide plate 30 and the upper sidewall 14 define a first airflow channel 16. In the third position, the air guide plate 30 and the lower sidewall 15 define a second airflow channel 17. Since the first airflow channel 16 is located on the upper side of the air guide plate 30, by making the air guide plate 30 and the upper sidewall 14 define the first airflow channel 16 in the second position, more airflow can be blown out of the air conditioner 100 from the upper first airflow channel 16, allowing the airflow to flow upward and leave the air conditioner 100. Since the second airflow channel 17 is located below the air guide plate 30, when the air guide plate 30 is in the third position, the air guide plate 30 and the lower side wall 15 define the second airflow channel 17. This allows more airflow to exit the air conditioner 100 from the lower second airflow channel 17 when the air guide plate 30 is in the third position, enabling the airflow to flow downwards and leave the air conditioner 100. The air blown out by the air conditioner 100 can be adjusted to flow upwards or downwards, making the adjustment of the air outlet 12 more flexible.

[0051] According to some embodiments of this utility model, refer to Figure 2 and Figure 3The air conditioner 100 has a heating mode and a cooling mode. In cooling mode, the air guide plate 30 is in the second position, and in heating mode, it is in the third position. Since hot air is lighter than cold air, in cooling mode, the cooler airflow from the air conditioner 100 will naturally fall due to gravity. By positioning the air guide plate 30 in the second position, it directs the cold air upwards, causing it to flow upwards and leave the air conditioner 100. The cold airflow naturally falls in the environment, resulting in a more uniform temperature. In heating mode, the warmer airflow from the air conditioner 100 will naturally rise in the environment. By positioning the air guide plate 30 in the third position, it presses the warm air downwards, causing it to flow downwards and leave the air conditioner 100. The warm airflow naturally rises in the environment, resulting in a more uniform temperature.

[0052] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The air guide plate 30 includes an air guide plate body 33, the cross-section of which is arc-shaped and perpendicular to the rotation axis of the air guide plate 30. In the second position, the air guide plate body 33 bends and protrudes downwards and backwards, and in the third position, it bends and protrudes upwards and forwards. By bending and protruding downwards and backwards in the second position, the air guide plate 30 can guide the airflow forwards, achieving air delivery over a longer distance. By bending and protruding upwards and forwards in the third position, the air guide plate 30 can press down the hotter airflow, causing the hotter airflow blown out of the air conditioner 100 to flow downwards and leave the air conditioner 100. The hot airflow naturally rises in the environment, making the ambient temperature more uniform.

[0053] According to some embodiments of this utility model, refer to Figure 2 and Figure 3 The maximum rotation angle of the air guide plate 30 is α, and the value of α ranges from 160° to 220°. The maximum rotation angle of the air guide plate 30 is the sum of the maximum angle that can be rotated in the first rotation direction and the maximum angle that can be rotated in the second rotation direction. For example, the maximum rotation angle α of the air guide plate 30 can be 160°, 180°, 200°, 220°, etc. By ensuring that the maximum rotation angle α of the air guide plate 30 is not less than 160°, the adjustable range of airflow of the air conditioner 100 can be increased, making the adjustment of the air outlet direction of the air guide plate 30 more flexible. By ensuring that the maximum rotation angle α of the air guide plate 30 is not greater than 220°, interference between the air guide plate 30 and its supporting structure can be avoided.

[0054] According to some embodiments of this utility model, refer to Figure 4 and Figure 5The drive mechanism 38 is located on one side of the air guide plate 30 in the left-right direction. By placing the drive mechanism 38 on one side of the air guide plate 30 in the left-right direction, it is convenient to install and fix the drive mechanism 38, and also convenient to connect the drive mechanism 38 to the air guide plate 30.

[0055] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The drive mechanism 38 includes a drive motor 39, and the rotation axis of the air guide plate 30 is coaxial with the rotation axis of the drive motor 39. By making the rotation axis of the air guide plate 30 coaxial with the rotation axis of the drive motor 39, it is easier for the drive motor 39 to drive the air guide plate 30 to move, and the structure is also more compact.

[0056] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The air guide plate 30 includes an air guide plate body 33 and a first connecting ear plate 34. The air guide plate body 33 has a first longitudinal end 35 and a second longitudinal end 36 at its two ends in the left-right direction. The first connecting ear plate 34 is located at the first longitudinal end 35. A drive mechanism 38 is connected to the first connecting ear plate 34. In the left-right direction, the drive mechanism 38 is located on the side of the corresponding first connecting ear plate 34 away from the second longitudinal end 36. By including the air guide plate body 33 and the first connecting ear plate 34 in the air guide plate 30, the connection between the air guide plate 30 and the drive mechanism 38 is made more convenient. By positioning the drive mechanism 38 on the side of the corresponding first connecting ear plate 34 away from the second longitudinal end 36, interference between the drive mechanism 38 and the air guide plate body 33 can be avoided.

[0057] According to some embodiments of this utility model, refer to Figure 5 The drive mechanism 38 includes a drive motor 39, the motor shaft of which is directly connected to the first connecting lug 34. By directly connecting the motor shaft of the drive motor 39 to the first connecting lug 34, the transmission structure between the drive motor 39 and the air guide plate 30 can be eliminated, making the structure of the drive mechanism 38 simple, reducing the number of parts in the air guide mechanism, and reducing assembly complexity.

[0058] According to some embodiments of this utility model, refer to Figure 5A mating hole 37 is formed on the side of the first connecting ear plate 34 facing the drive motor 39. The mating hole 37 is a blind hole, and the motor shaft is inserted into the mating hole 37. By forming the mating hole 37 on the side of the first connecting ear plate 34 facing the drive motor 39 and inserting the motor shaft into the mating hole 37, the connection and installation between the motor shaft and the first connecting ear plate 34 can be simplified. By making the mating hole 37 a blind hole, the bottom wall of the mating hole 37 can limit the motor shaft, preventing excessive movement of the motor shaft in the direction of the first connecting ear plate 34, which could cause interference between the motor shaft and the air guide plate 30. Furthermore, it can also reduce the amount of motor shaft exposed through the mating hole 37, improving safety.

[0059] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 A baffle plate 18 is provided inside the housing 10. The baffle plate 18 is located on at least one side of the air outlet duct 13 in the left-right direction. A receiving cavity is defined between the baffle plate 18 and the housing 10, and at least a portion of the drive mechanism 38 is located within the receiving cavity. By providing a baffle plate 18 inside the housing 10 and placing at least a portion of the drive mechanism 38 within the receiving cavity, the baffle plate 18 can shield and protect the drive mechanism 38, preventing damage to the drive mechanism 38 from impacts by other components in the air conditioner 100; it also prevents the drive mechanism 38 from being exposed, making the air conditioner 100 more aesthetically pleasing overall.

[0060] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The baffle plate 18 is detachably connected to the housing 10. By making the baffle plate 18 detachably connected to the housing 10, it is convenient to maintain the drive mechanism 38.

[0061] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The air outlet 12 extends in the left-right direction, and there are multiple air guide plates 30 arranged sequentially in the left-right direction. The number of drive mechanisms 38 is the same as the number of air guide plates 30 and they correspond one-to-one. Each drive mechanism 38 is connected to the corresponding air guide plate 30. For example, if there are two air guide plates 30, there are also two drive mechanisms 38. By making the number of drive mechanisms 38 the same as the number of air guide plates 30 and ensuring they correspond one-to-one, each air guide plate 30 can rotate independently through the drive mechanism 38, allowing different air guide plates 30 to guide airflow at different angles at different positions. Furthermore, by driving multiple air guide plates 30 to rotate through multiple drive mechanisms 38, the air direction of each air guide plate 30 can be controlled individually, achieving the effect of zoned airflow.

[0062] For example, multiple air guide plates 30 can be made to rotate in the same direction and at the same angle as needed; or multiple air guide plates 30 can be made to rotate in the same direction and at different angles as needed; or multiple air guide plates 30 can be made to rotate in different directions as needed.

[0063] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 There are two air guide plates 30 and two drive mechanisms 38. By having two air guide plates 30 and two drive mechanisms 38, driven by different motors, the air guide plate 30 can be controlled independently to achieve the effect of zoned air supply.

[0064] For example, the two air guide plates 30 can be rotated in the same direction and at the same angle as needed; or, as needed, the two air guide plates 30 can be rotated in the same direction and at different angles; or, as needed, the two air guide plates 30 can be rotated in different directions.

[0065] For example, when the indoor unit of the air conditioner is installed in the middle platform of the stairwell, the two air guides 30 can be adjusted to different angles so that one side of the air conditioner 100 blows upward and the other side blows downward, taking into account the air supply conditions of the stairwell areas on both sides.

[0066] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The housing 10 contains a connecting bracket 20, at least a portion of which is located between two air guide plates 30. In the left-right direction, two drive mechanisms 38 are respectively located on the side of the corresponding air guide plate 30 furthest from the connecting bracket 20. Both air guide plates 30 are rotatably connected to the connecting bracket 20. For example, the air conditioner 100 includes two air guide plates 30 and two drive mechanisms 38. The two air guide plates 30 are arranged in the left-right direction, and the connecting bracket 20 is located between them. The drive mechanism 38 connected to the left air guide plate 30 is located on the left side of that air guide plate 30, and the drive mechanism 38 connected to the right air guide plate 30 is located on the right side of that air guide plate 30. By positioning the two drive mechanisms 38 on the side of the corresponding air guide plate 30 furthest from the connecting bracket 20 in the left-right direction, interference between the drive mechanisms 38 and the connecting bracket 20 can be avoided, and the drive mechanisms 38 can also be prevented from blocking the air outlet 12, thus reducing the airflow. By rotatably connecting both air guide plates 30 to the connecting bracket 20, the rotational connection between the air guide plates 30 and the housing 10 is facilitated. Alternatively, the two air guide plates 30 can rotate independently, allowing them to guide the airflow at different angles from different positions.

[0067] For example, the air guide plate 30 includes an air guide plate body 33, a first connecting ear plate 34, and a second connecting ear plate 34a. The air guide plate body 33 has a first longitudinal end 35 and a second longitudinal end 36 at its two ends in the left-right direction, respectively. The first connecting ear plate 34 is located at the first longitudinal end 35, and the second connecting ear plate 34a is located at the second longitudinal end 36. The drive mechanism 38 is connected to the first connecting ear plate 34, and the second connecting ear plate 34a is rotatably connected to the connecting bracket 20. The connecting bracket 20 includes a bracket plate and rotating shafts located on the left and right sides of the bracket plate. The bracket plate is connected to the housing 10. The second connecting ear plates 34a of both air guide plates 30 are provided with rotating holes, and the rotating shafts pass through the rotating holes.

[0068] According to some embodiments of this utility model, refer to Figure 4 and Figure 5 The rotation axes of the multiple air guide plates 30 are coaxially arranged. By making the rotation axes of the multiple air guide plates 30 coaxial, it is convenient to arrange the multiple air guide plates 30 in the left and right direction, and the overall structural layout is simplified.

[0069] The following reference Figures 1-5 Refer to the air conditioner 100 according to some embodiments of the present invention.

[0070] In this embodiment, the air conditioner 100 is a split-type wall-mounted air conditioner 100, which includes an outdoor unit and an indoor unit. The indoor unit includes a housing 10, a heat exchanger assembly, an air duct assembly, an air guide plate 30, and a drive mechanism 38. The housing 10 has an air inlet, an air outlet 12, and an air outlet duct 13.
