Description

Technical Field

[0001] This application relates to the field of air conditioning technology, for example to an indoor unit and an air conditioner. Background Technology

[0002] Currently, existing indoor units generally exhaust air from the front, and the direction of airflow is adjusted left and right or up and down by swivel blades. On the one hand, when heating, hot air will rise because of its low density, and even with swivel blades to adjust the airflow direction, it is still not possible to achieve rapid heating. On the other hand, when cooling, it is easy to cause direct airflow to people when there are people moving around in the room.

[0003] The related technology discloses an indoor unit with dual air outlets. The indoor unit achieves air outlets from the front and bottom by setting a front air outlet and a bottom air outlet. By setting and controlling the opening and closing of the front air outlet and the bottom air outlet, the problem of rapid heating and cooling without direct airflow is solved.

[0004] In the process of implementing the embodiments of this disclosure, at least the following problems were found in the related art: In related technologies, while indoor units with dual air outlets can solve the problem of rapid heating and cooling without direct airflow, they cannot distribute the airflow to the front and bottom, which can easily lead to uneven air distribution.

[0005] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art.

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0020] For ease of description, the length and height of the air duct in this application are as follows: Figure 1 As shown, the front and back directions are also as shown. Figure 1 As shown in the figure. The axis of the front air outlet is shown as O in the figure.

[0021] Combination Figures 1 to 22As shown, this embodiment of the present disclosure provides an indoor unit, which includes a housing 10 and a heat exchange assembly. The housing 10 defines an air duct with an air inlet and an air outlet, the air outlet including a front air outlet 11 and a lower air outlet 12. The heat exchange assembly is located within the air duct 13 and includes a fan 16 and a heat exchanger 15. The fan 16 can drive the airflow from the air inlet into the air duct 13, exchange heat with the heat exchanger 15, and then flow out from the front air outlet 11 and / or the lower air outlet 12. Optionally, the air inlet is located at the bottom or rear end of the housing 10. By providing a front air outlet 11 and a lower air outlet 12, when the indoor unit is heating, air is discharged from the lower air outlet 12, and the hot air, due to its lower density, will flow upward, improving the heating effect. When the indoor unit is cooling, air is discharged from the front air outlet 11, which can prevent cold air from blowing directly on the user, and the cold air flows downward, which can improve the cooling range and cooling effect.

[0022] Optionally, such as Figures 2 to 8 As shown, the indoor unit also includes a deflector 20, which is movably located within the air duct 13. The deflector 20 is used to adjust the airflow to the front air outlet 11 and the lower air outlet 12. In this way, the deflector 20 can not only distribute the airflow to the front air outlet 11 and the lower air outlet 12, but also flexibly adjust the airflow to the front air outlet 11 and the lower air outlet 12 through its movement. When both the front air outlet 11 and the lower air outlet 12 are discharging air, the deflector 20 can be used to adjust the airflow of both outlets. When only one of the outlets is discharging air, the deflector 20 can also adjust the airflow of that outlet, further improving the airflow diversity of the indoor unit, precisely controlling the airflow and direction of the indoor unit, and enhancing the user experience.

[0023] Optionally, the indoor unit also includes a first air guide 30, which is located at the front air outlet 11 and used to control the opening and closing of the front air outlet 11. This allows the front air outlet 11 to be independently controlled, improving the flexibility of airflow. Optionally, the indoor unit also includes a second air guide 40, which is located at the lower air outlet 12 and used to control the opening and closing of the lower air outlet 12. This allows the lower air outlet 12 to be independently controlled, improving the flexibility of airflow.

[0024] Optionally, such as Figure 2 As shown, the heat exchange component has an air outlet space 131 on the air outlet side, a front air outlet 11 is located on the front side wall of the air outlet space 131, a lower air outlet 12 is located on the bottom wall of the air outlet space 131, and the air duct 13 includes the air outlet space 131; wherein, the guide plate 20 is movably located in the air outlet space 131.

[0025] In this embodiment, both the front air outlet 11 and the lower air outlet 12 are located within the air outlet space 131. This allows the heat exchange airflow passing through the heat exchange components to exit from the front air outlet 11 and / or the lower air outlet 12, ensuring the efficient airflow and the cooling or heating effect of the indoor unit. Furthermore, the guide vane 20 is movably positioned within the air outlet space 131, allowing it to directly act on the airflow exiting the heat exchange components. This shortens the airflow adjustment path, reduces airflow loss within the duct 13, and improves the response speed and accuracy of airflow adjustment. Simultaneously, it makes the duct 13 structure more compact, optimizes the internal space layout of the housing 10, reduces the overall size of the indoor unit, and facilitates installation.

[0026] Optionally, the fan 16 and heat exchanger 15 are arranged sequentially along the airflow direction within the duct 13. This reduces airflow stagnation losses within the heat exchange components, improves the contact efficiency between the airflow and the heat exchanger 15, and thus enhances the heat exchange effect. It can be understood that in some optional embodiments, the heat exchanger 15 and fan 16 are arranged sequentially along the airflow direction within the duct 13. In practical applications, the fan 16 and heat exchanger 15 can be configured according to actual needs. Indoor units with a guide vane 20 on the air outlet side of the heat exchange components are all optional embodiments of this application.

[0027] In some optional embodiments, the baffle 20 may also be disposed between the fan 16 and the heat exchanger 15, or disposed on the air inlet side of the heat exchange component. Any method that can adjust the air volume of the front air outlet 11 and the lower air outlet 12 by diverting the airflow in the air duct 13 is an optional embodiment of this application.

[0028] Optionally, combined Figures 2 to 5 ,in, Figure 4 and Figure 5 The dashed arrows indicate the airflow direction above the guide vane, and the solid arrows indicate the airflow direction below the guide vane. The guide vane 20 can move between a first position and a second position, such as... Figure 4 As shown, when the guide vane 20 is in the first position, the guide vane 20 avoids the front air outlet 11 and the lower air outlet 12, and the airflow in the air duct 13 flows from one side of the guide vane 20 to the front air outlet 11 and the lower air outlet 12; as Figure 5 As shown, when the guide plate 20 is in the second position, the guide plate 20 is located between the front air outlet 11 and the lower air outlet 12. The airflow of the air outlet space 131 flows from the upper side of the guide plate 20 to the front air outlet 11 and from the lower side of the guide plate 20 to the lower air outlet 12.

[0029] In this embodiment, the air deflector 20 can switch between a first position and a second position. When in the first position, it avoids the dual air outlets, allowing simultaneous airflow from both outlets to meet the rapid temperature control requirements of large spaces. When in the second position, the air deflector 20 forms a flow-dividing structure between the dual air outlets, ensuring that the airflow accurately flows from the upper and lower sides of the air deflector 20 to the corresponding air outlets, preventing turbulence and crossflow within the air outlet space 131. The flexible switching between these two positions further expands the airflow modes and improves the user experience.

[0030] Optionally, such as Figure 2 and Figure 4 As shown, when the guide vane 20 is in the first position, the angle between the guide vane 20 and the axis of the front air outlet 11 is less than or equal to a first set angle. In this way, the axis of the guide vane 20 is parallel or approximately parallel to the axis of the front air outlet 11. The guide vane 20 will not obstruct the airflow flowing towards the front air outlet 11, nor will it affect the airflow flowing towards the lower air outlet 12. This avoids the front air outlet 11 and the lower air outlet 12, and at least part of the airflow in the duct 13 can flow towards the front air outlet 11 and the lower air outlet 12 from the same side of the guide vane 20.

[0031] Optionally, when the deflector 20 is in the first position, the deflector 20 is located above the front air outlet 11. In this way, the deflector 20 will not affect the airflow to the front air outlet 11 and the lower air outlet 12. The airflow in the duct 13 flows from the lower side of the deflector 20 to the front air outlet 11 and the lower air outlet 12, thus avoiding the deflector 20 from diverting the airflow.

[0032] Optionally, when the deflector 20 is in the first position, the height of the deflector 20 is less than or equal to the height of the top of the front air outlet 11. This way, not only does the airflow below the deflector 20 flow to both the front air outlet 11 and the lower air outlet 12, but there is also airflow above the deflector 20 flowing to the front air outlet 11.

[0033] Optionally, such as Figure 3 As shown, when the guide plate 20 is in the second position, the angle α between the axis of the guide plate 20 and the front air outlet 11 is greater than the first set angle, and the guide plate 20 guides part of the airflow in the air duct 13 to the lower air outlet 12. Specifically, when the guide plate 20 is in the second position, the guide plate 20 can guide part of the airflow from the heat exchange component to flow down to the lower air outlet 12 under the guidance of the guide plate 20.

[0034] Here, when the guide vane 20 moves to a position with a large angle to the axis of the front air outlet 11, the guide vane 20 has a certain length at the height of the air duct 13. In this way, the guide vane 20 can guide the airflow in the air duct 13 to flow at the height of the air duct 13, and can guide part of the airflow in the air duct 13 to the lower air outlet 12. At the same time, the airflow above the guide vane 20 can still flow to the front air outlet 11, thus realizing the air distribution effect of the guide vane 20.

[0035] Optionally, when the deflector 20 is in the second position, the orthographic projection of the deflector 20 from back to front has a set height in the height direction, and the orthographic projection is located inside the front air outlet 11. In this way, the deflector 20 can block part of the airflow from flowing to the front air outlet 11 and guide this part of the airflow to flow to the downward air outlet 12.

[0036] Optionally, when the guide vane 20 is in the second position, the guide vane 20 is inclined downward in the direction from back to front, and the guide vane 20 is located between the front air outlet 11 and the lower air outlet 12. Alternatively, when the guide vane 20 is in the second position, the guide vane 20 extends vertically along the height direction of the air duct 13, so that the airflow passing through the guide vane 20 in the air duct 13 can flow to the lower air outlet under the guidance of the guide vane 20.

[0037] Optionally, such as Figure 5 As shown, when the guide plate 20 is in the second position, the lower end of the guide plate 20 corresponds to the middle of the lower air outlet 12. In this way, the airflow from the heat exchange component flows to the lower air outlet 12 under the guidance of the guide plate 20, and can flow out from the lower air outlet.

[0038] Optionally, the height of the highest point of the deflector 20 is less than or equal to the height of the top of the front air outlet 11. This allows the airflow above the deflector 20 to quickly reach the front air outlet 11 when the deflector 20 is in the second position, without completely obstructing the airflow within the duct towards the front air outlet. Optionally, the height of the highest point of the deflector 20 is greater than or equal to the height of the bottom of the front air outlet 11. This allows the deflector 20 to segment the airflow within the duct 13 corresponding to the front air outlet 11 when the deflector 20 is in the second position, improving the uniformity of airflow.

[0039] Optionally, the first set angle includes 5°~45°, 5°~30°, or 5°~20°. It can be understood that the first set angle is the critical angle for the airflow distribution and avoidance by the deflector 20. In practical applications, it can be set according to the relative position and size of the deflector 20 with the front air outlet 11 and the lower air outlet 12. Any scheme that enables the deflector 20 to distribute airflow and avoid obstacles is an optional embodiment of this application.

[0040] Optionally, the rotation angle of the guide vane 20 includes 5°~150°, or 5°~120°, or 5°~90°, or 5°~60°, or 10°~60°. Here, the rotation angle of the guide vane 20 refers to the maximum angle range that the guide vane 20 can rotate relative to the axis of rotation. By setting the rotation angle of the guide vane 20, a wider airflow direction coverage can be achieved, improving the airflow pattern.

[0041] Optionally, when the guide vane 20 is in the first position, the angle between the guide vane 20 and the axis of the front air outlet 11 is the first included angle; when the guide vane 20 is in the second position, the angle between the guide vane 20 and the axis of the front air outlet 11 is the second included angle α; wherein, the first included angle includes 0°~20°, and / or, the second included angle α includes 20°~90°. The smaller angle of the first included angle in the first position ensures that the airflow passes through the guide vane 20 and flows to the front air outlet 11 without obstruction. The angle of the second included angle in the second position ensures stable airflow guidance during diversion, avoiding the problem of increased airflow resistance due to an excessively large second included angle and incomplete diversion due to an excessively small second included angle, thus improving the stability and reliability of airflow regulation. Here, the first included angle and the second included angle can be set according to the size of the guide vane 20 and the size of the indoor unit, and the angle range that can achieve the functions of avoidance and diversion is within the optional embodiments of this application.

[0042] Optionally, the difference between the second included angle and the first included angle can range from 5° to 60°.

[0043] Optionally, the second position is not unique. The guide plate 20 has multiple second positions. When the guide plate 20 is in different second positions, the amount of separation of the airflow in the air duct 13 by the guide plate 20 is different. That is to say, when the guide plate 20 is in different second positions, the airflow to the front air outlet 11 is different, and the airflow to the lower air outlet 12 is also different.

[0044] Optionally, the width of the guide vane 20 is less than the shortest distance between the heat exchange component and the front air outlet 11 in the front-rear direction. This ensures the rotation space of the guide vane 20 and avoids interference between the guide vane 20 and the heat exchange component.

[0045] Optionally, the guide vane 20 includes a rotating end and a free end arranged opposite each other along the width direction. The rotating end is rotatably connected to the housing 10, so that the guide vane 20 can rotate around the rotating end. In this way, the height of one end of the guide vane 20 in the width direction is fixed. By driving the guide vane 20 to rotate, the height of the free end can be changed, thereby adjusting the position of the guide vane 20, realizing different guiding functions, and also facilitating the driving of the guide vane 20.

[0046] Optionally, when the guide vane 20 is in the first position, the rotating end and the free end are arranged along the direction from the heat exchange assembly to the front air outlet 11; when the guide vane 20 is in the second position, the rotating end is located above the free end to ensure that the guide vane 20 has sufficient space to move. Optionally, when the guide vane 20 is in the first position, the distance between the rotating end and the heat exchange assembly is less than the distance between the free end and the front air outlet 11.

[0047] It should be noted that the angle between the aforementioned guide vane 20 and the axis of the front air outlet 11 refers to the angle between the width of the guide vane 20 or the tangent in the width direction of the guide vane 20 and the axis of the front air outlet 11.

[0048] Optionally, the indoor unit includes a controller that is electrically connected to the first air guide 30, the second air guide 40, and the deflector 20. The controller is configured to control the movement of the first air guide 30, the second air guide 40, and the deflector 20.

[0049] Optionally, when the indoor unit is operating in heating mode, the controller is configured to control the first air guide 30 to close the front air outlet 11, control the second air guide 40 to open the lower air outlet 12, and control the deflector 20 to move to the first position. Here, when the indoor unit is operating in heating mode, the deflector 20 is in the first position, which can avoid the front air outlet 11 and the lower air outlet 12. The front air outlet 11 is closed, and the lower air outlet 12 is open. The hot airflow is concentrated and flows out from the lower air outlet 12, quickly achieving vertical circulation in the space, thus achieving the purpose of rapid heating.

[0050] Optionally, when the indoor unit is operating in cooling mode, the controller is configured to control the first air guide 30 to open the front air outlet 11, control the second air guide 40 to close the lower air outlet 12, and control the deflector 20 to move to the first position. Here, when the indoor unit is operating in heating mode, the deflector 20 is in the first position, which can avoid the front air outlet 11 and the lower air outlet 12. The front air outlet 11 needs to be opened to ensure air volume and increase the air outlet distance, thereby achieving rapid cooling.

[0051] Optionally, if the air outlet space of the indoor unit includes a first target space and a second target space, and the distance between the first target space and the indoor unit is less than or equal to a set distance, and the distance between the second target space and the indoor unit is greater than the set distance, the indoor unit is configured to control the first air guide 30 to open the front air outlet 11, control the second air guide 40 to open the lower air outlet 12, and adjust the position of the deflector 20 according to the environmental parameters and / or user information of the first and second target spaces.

[0052] In this embodiment, when the air outlet area of ​​the indoor unit includes a near-distance first target space and a far-distance second target space, the controller controls both the front air outlet 11 and the lower air outlet 12 to open. This increases the air volume of the indoor unit, ensuring that the lower air outlet 12 provides cooling or heating for the near-distance space, while the front air outlet 11 provides cooling or heating for the far-distance space, eliminating dead zones and achieving full-area air supply. With airflow from both the front air outlet 11 and the lower air outlet 12, the airflow of the front air outlet 11 and the lower air outlet 12 can be adjusted by changing the position of the guide vane 20, further improving the accuracy of the indoor unit's airflow and enhancing the user experience. Here, the first target space and the second target space can be two rooms or different locations within the same room.

[0053] Optionally, the deflector 20 is defined as being located in, for example... Figure 2 The angle of the deflector 20 at the position shown is the initial angle, and the deflector 20 is located as shown. Figure 3 The angle of the deflector 20 at the indicated position is the target angle. Rotating the deflector 20 from the initial angle toward the target angle is defined as increasing the angle, and rotating it from the target angle toward the initial angle is defined as decreasing the angle. Here, the initial angle can be the angle of the first position, and the target angle can be any angle of the second position or the maximum angle the deflector 20 can rotate away from the first position.

[0054] Optionally, the deflector 20 is configured such that, when the angle is reduced, the airflow to the forward air outlet 11 increases, and the airflow to the downward air outlet 12 decreases. Conversely, when the angle is increased, the deflector 20 is configured such that, when the angle is increased, the airflow to the forward air outlet 11 decreases, and the airflow to the downward air outlet 12 increases.

[0055] Optionally, the environmental parameters include temperature. Adjusting the position of the deflector 20 according to the environmental parameters of the first target space and the second target space includes: adjusting the position of the deflector 20 according to the temperature of the first target space and the second target space.

[0056] Optionally, if the difference between the temperature of the first target space and the first set temperature is greater than or equal to the first preset difference, and the difference between the temperature of the second target space and the first set temperature is less than the first preset difference, the controller is configured to control the guide vane 20 to increase the angle.

[0057] At this time, the difference between the first target space and the first set temperature is large, indicating that the temperature difference between the nearby space and the set temperature is large. At this time, the angle of the baffle plate 20 is increased to increase the air volume of the lower air outlet 12, thereby increasing the air volume of the first target space for rapid heating or cooling.

[0058] Optionally, if the temperature difference between the first target space and the first set temperature is less than the first preset difference, and the temperature difference between the second target space and the first set temperature is greater than or equal to the first preset difference, the controller is configured to control the guide vane 20 to reduce its angle.

[0059] At this time, the temperature difference between the second target space and the first set temperature is large, indicating that the temperature difference between the space and the set temperature is large. At this time, the angle of the baffle plate 20 is reduced to increase the air volume of the front air outlet 11. By using the long-distance air supply of the front air outlet 11, the air volume of the second target space is increased, so as to achieve rapid heating or cooling of the second target space.

[0060] Optionally, the environmental parameters include indoor humidity. Adjusting the position of the deflector 20 according to the environmental parameters of the first target space and the second target space includes: adjusting the position of the deflector 20 according to the humidity of the first target space and the second target space.

[0061] Optionally, the position of the deflector 20 is adjusted according to the humidity of the first and second target spaces. This includes: when the indoor unit is operating in cooling mode and the humidity of the first target space is greater than a humidity threshold, the controller is configured to control the deflector 20 to reduce its angle. This increases the airflow from the front air outlet 11 and reduces the airflow from the lower air outlet 12, preventing the air from the lower air outlet 12 from blowing directly onto the ground and avoiding condensation on the ground.

[0062] Optionally, the user information includes the number of users. Adjusting the position of the guide vane 20 based on the user information of the first target space and the second target space includes: adjusting the position of the guide vane 20 based on the number of users in the first target space and / or the number of users in the second target space.

[0063] Optionally, when the guide vane 20 rotates to the intermediate angle, the airflow from the air duct 13 to the forward air outlet 11 and the downward air outlet 12 is the same. Optionally, the intermediate angle can be any angle between the initial angle and the target angle, or it can be the target angle.

[0064] Optionally, after the guide vane 20 rotates by a preset angle from the target angle, the guide vane 20 is positioned at the intermediate angle. When the guide vane 20 is positioned at the intermediate angle, the angle between the guide vane 20 and the axis of the front air outlet 11 is the angle between the guide vane 20 and the axis of the front air outlet 11 at the initial angle plus the preset angle. Optionally, if the preset angle is 60°, and the angle between the guide vane 20 and the axis of the front air outlet 11 at the initial angle is 0°, then when the guide vane 20 is positioned at the intermediate angle, the angle between the guide vane 20 and the axis of the front air outlet 11 is 60°.

[0065] Optionally, the position of the deflector 20 is adjusted according to the number of users in the first target space and / or the number of users in the second target space, including: when there are users in the first target space and no users in the second target space, the controller controls the deflector 20 to move to the middle angle so that the air volume of the front air outlet 11 and the lower air outlet 12 is the same.

[0066] Optionally, the position of the deflector 20 can be adjusted according to the number of users in the first target space and / or the number of users in the second target space. This includes: when there are no users in the first target space and there are users in the second target space, the controller controls the deflector 20 to reduce its angle to increase the air volume of the front air outlet 11 and ensure the cooling or heating effect of the second target space at a distance.

[0067] Optionally, the deflector 20 includes a windward surface 213 and a leeward surface 214 disposed opposite to each other along the thickness direction. When the deflector 20 is in the second position, the windward surface 213 is located on the rear side of the deflector 20.

[0068] Optionally, such as Figures 5 to 8 As shown, the guide plate 20 protrudes along the direction from the windward side 213 to the leeward side 214. Optionally, the guide plate 20 is provided with a guiding structure 21, wherein the windward side 213 and / or the leeward side 214 are provided with the guiding structure 21. In this embodiment of the present disclosure, the windward side 213 and the leeward side 214 of the guide plate 20 protrude or are provided with a guiding structure 21, which can perform secondary sorting of the airflow. The protruding guide plate 20 can guide the airflow to flow along a smooth curved surface, reducing turbulence and noise caused by airflow impact. The guiding structure 21 can further regulate the airflow direction, avoid uneven local airflow velocity, improve the smoothness and uniformity of air supply, and at the same time reduce the resistance when the airflow passes through, indirectly improving the heat exchange efficiency and air supply efficiency.

[0069] Optionally, when the deflector 20 is in the first position, the windward side 213 faces downward, and the windward side 213 is provided with a guiding structure 21. In this way, the guiding structure 21 of the windward side 213 can also guide and soften the airflow flowing towards the front air outlet 11, reduce noise, reduce resistance, and further increase the air outlet distance of the front air outlet 11. When there is also airflow above the deflector 20, the guiding ribs of the leeward side 214 can also soften the airflow and reduce noise. When the deflector 20 is in the second position, there is airflow on both the windward side 213 and the leeward side 214. The guiding structures 21 of the windward side 213 and the leeward side 214 can guide and soften the airflow flowing towards the front air outlet 11 and the lower air outlet 12, respectively.

[0070] Optionally, the deflector 20 protrudes in an arc shape along the direction from the windward side 213 to the leeward side 214. Compared to a normal flat or simple protruding structure, the arc-shaped protrusion can guide airflow more efficiently and reduce frictional resistance when airflow passes through. It can be understood that the deflector can also be a straight plate or other shapes.

[0071] Optionally, such as Figure 8 As shown, the flow guiding structure 21 includes flow guiding ribs that extend along the width direction of the flow guiding plate 20. Multiple flow guiding ribs are spaced apart along the length direction of the flow guiding plate 20. The width-direction extension of the flow guiding ribs aligns with the airflow direction, guiding the airflow to flow uniformly along the width direction of the flow guiding plate 20 and preventing airflow accumulation in localized areas. The spaced-apart length-direction arrangement of multiple flow guiding ribs divides the airflow into multiple parallel airflow streams, reducing interference between adjacent airflows and further suppressing turbulence.

[0072] Optionally, the distance between adjacent guide ribs is 1~3mm.

[0073] In this embodiment, the distance between adjacent guide ribs within the aforementioned range ensures that the combing effect of adjacent guide ribs does not overlap, improving noise and airflow performance. When the distance between adjacent guide ribs is less than 1 mm, the close proximity of the guide ribs leads to increased airflow resistance. When the distance between adjacent guide ribs is greater than 3 mm, the excessive distance between the guide ribs results in insufficient combing.

[0074] Optionally, the height of the guide ribs is less than or equal to 1 mm to ensure the guiding effect of the guide ribs and avoid the overlapping of the guiding effects of adjacent guide ribs.

[0075] Optionally, the ratio of the projected area of ​​the guide rib on the guide plate 20 to the area of ​​the guide plate 20 is 2% to 10% to ensure the guiding effect of the guide rib. The projected area of ​​the guide rib on the guide plate 20 refers to the area of ​​the orthographic projection of the guide rib in the direction perpendicular to the guide plate 20.

[0076] Optionally, the windward side 213 and the leeward side 214 are provided with different guide rib structures.

[0077] Optionally, the windward surface 213 is provided with a first guide rib 211, which is trapezoidal and includes the first guide rib 211. Here, the airflow velocity on the windward surface 213 is relatively fast, and the trapezoidal first guide rib 211 on the windward surface 213 can enhance the airflow guidance, and the inclined surface of the trapezoidal structure can guide the airflow to transition smoothly.

[0078] Optionally, the leeward side 214 is provided with a second guide rib 212, which is semi-circular. Optionally, the diameter of the second guide rib 212 is less than 1.5 mm, and the guide rib includes the second guide rib 212.

[0079] Here, the leeward side 214 is a semi-circular second guide rib 212 with a diameter of less than 1.5 mm. This reduces the generation of vortices in the airflow on the leeward side and lowers airflow noise.

[0080] In this embodiment of the disclosure, by setting two different types of guide ribs on the windward side 213 and the leeward side 214, the airflow state on the windward and leeward sides can be optimized in a targeted manner, thereby further improving the smoothness of airflow and reducing noise.

[0081] Optionally, the windward side 213 is provided with multiple first guide ribs 211, and the leeward side 214 is provided with multiple second guide ribs 212. The first guide ribs 211 and second guide ribs 212 are staggered. In this way, the staggered first guide ribs 211 and second guide ribs 212 form a staggered coverage in the length direction. The staggered layout can fill the blind spots in the airflow through the stagger, ensuring that the airflow can be effectively regulated in the entire length direction of the guide plate 20, and avoiding uneven velocity of local airflow due to not contacting the guide ribs. It can be understood that the guide ribs can also be other shapes, such as rectangles, polygons, etc., and the airflow guiding structure 21 can also be other structures besides guide ribs, such as protruding structures, biomimetic structures, grooves, or perforated structures. All schemes that can guide the airflow in the air duct 13 are optional embodiments of this application.

[0082] Optionally, such as Figure 6 and Figure 7 As shown, the guide vane 20 rotates about its length, that is, the guide vane 20 rotates about its length. In this way, the width of the guide vane 20 can change its extension direction and position within the air duct 13, thereby achieving the regulation of the airflow within the air duct 13.

[0083] Optionally, the housing 10 includes a first sidewall and a second sidewall disposed opposite to each other along the length of the air duct 13, and the guide plate 20 includes a first end and a second end disposed along the length of the guide plate 20. The first end is rotatably connected to the first sidewall, and the second end is rotatably connected to the second sidewall. The guide plate 20 also includes a first driving mechanism 22, which is drivenly connected to the first end and / or the second end. The first driving mechanism 22 is used to drive the guide plate 20 to rotate.

[0084] In this embodiment, the two ends of the guide plate 20 along its length are rotatably connected to the two side walls along the length of the air duct 13, which not only ensures the stable setting of the guide plate 20 but also guarantees its movement. The first drive mechanism 22 is connected to the first end and / or the second end, so that the first drive mechanism 22 does not occupy the space within the air duct 13 and also avoids affecting the airflow within the air duct 13.

[0085] Optionally, the first drive mechanism 22 is located outside the air duct 13, which can further reduce the space occupied by the air duct 13. Optionally, the housing 10 defines the air duct 13 and the receiving cavity, the receiving cavity is located at one end of the length direction of the air duct 13, and the first drive mechanism 22 is disposed in the receiving cavity.

[0086] Optionally, the guide vane can be slidably, translatably, or otherwise disposed within the air duct. Optionally, the guide vane can also be driven by other methods, such as gear and rack transmission, slider and groove transmission, or the side wall of the housing can be defined with a sliding groove, so that the end of the guide vane can move within the sliding groove to move the guide vane to different positions.

[0087] Optionally, the deflector 20 is detachably connected to the housing 10. This facilitates the removal of the deflector 20 for inspection, replacement, and cleaning.

[0088] Optionally, such as Figure 7 As shown, both the first and second ends are provided with one of a limiting groove 24 and a rotating shaft 23, and the first and second sidewalls are provided with the other of a limiting groove 24 and a rotating shaft 23. The limiting groove 24 is rotatably sleeved on the outside of the rotating shaft 23. The limiting groove 24 has a release port 241, allowing the rotating shaft 23 to disengage from the limiting groove 24 through the release port 241, thus detaching the guide plate 20 from the air outlet space 131. The rotating shaft 23 and the limiting groove 24 enable the rotation of the guide plate 20. Simultaneously, the limiting groove 24 has a release port 241, allowing the rotating shaft 23 to not only rotate within the limiting groove 24 but also disengage from it, thus realizing the rotation and disassembly of the guide plate 20.

[0089] Optionally, the housing 10 includes an air outlet side plate and an air outlet flange. The air outlet side plate has an air outlet, which includes a front air outlet 11 and / or a lower air outlet 12. The air outlet flange is located at the air outlet, and air guides are located on the air outlet flange. The air guides include a first air guide 30 and / or a second air guide 40. The air outlet flange provides installation space for the air guides and also improves the installation stability of the air guides.

[0090] Optionally, such as Figure 9 and Figure 10 As shown, the indoor unit also includes a second drive mechanism, which is driven by the air guide component to drive its movement. The second drive mechanism is located on the air outlet side panel, with one end of the air guide component passing through the air outlet flange and connected to it. This placement of the second drive mechanism on the air outlet side panel, and on one side of the air outlet flange, prevents it from occupying space at the air outlet or within the air outlet flange, thus avoiding any impact on the airflow. Furthermore, mounting the second drive mechanism on the air outlet side panel facilitates its disassembly and maintenance.

[0091] Optionally, the air outlet flange and the air outlet side plate are detachably connected. This allows the air outlet flange to be disassembled, and also allows the air guide components installed inside the air outlet flange to be disassembled and installed, improving the ease of disassembly and assembly of the air guide components.

[0092] Optionally, such as Figure 16 and Figure 18 As shown, the surface of the first air guide 30 and / or the surface of the second air guide 40 are provided with a gentle airflow structure 34. The gentle airflow structure 34 can divide the airflow at the air outlet into multiple low-speed fine streams, reduce the airflow speed, avoid direct airflow, improve the efficiency of cooling or heating, and enhance the user experience.

[0093] Optionally, such as Figure 12 As shown, the indoor unit also includes a water collection tray 50, which is located within the air duct 13. The water collection tray 50 has a clearance groove corresponding to the lower air outlet 12. The two ends of the second air guide 40 along its length are rotatably connected to the two side walls along the length of the clearance groove. In this embodiment, the side walls of the clearance groove of the water collection tray 50 directly support the second air guide 40, eliminating the need for an additional air guide plate bracket within the air duct 13. This avoids the air guide plate bracket obstructing airflow and ensures the air delivery efficiency of the lower air outlet 12. Furthermore, it improves the structural compactness within the air duct 13, reduces the space occupied by the air guide plate, and is particularly suitable for miniaturized indoor units.

[0094] Optionally, such as Figures 15 to 19 As shown, the first air guide includes multiple first sway vanes 31, which are movably disposed at the front air outlet 11 to adjust the airflow volume of the front air outlet 11. The first sway vanes 31 can adjust the airflow direction of the front air outlet 11, further improving the flexibility of adjusting the airflow volume and direction of the front air outlet 11. Optionally, the first sway vanes extend along the height direction of the front air outlet.

[0095] Optionally, such as Figure 9 and Figure 10 As shown, the second air guide includes multiple second swing blades 41, which are movably disposed at the lower air outlet 12 to adjust the airflow volume of the lower air outlet 12. The second swing blades 41 can adjust the airflow direction of the lower air outlet 12, further improving the flexibility of adjusting the airflow volume and direction of the lower air outlet 12. Optionally, the multiple second swing blades 41 are drivenly connected to a second lower drive mechanism via a second connecting rod 42. The second lower drive mechanism is used to drive the multiple second swing blades to rotate, and the second drive mechanism includes a second lower drive mechanism 43. Optionally, the second swing blades extend in the front-to-back direction.

[0096] Optionally, the housing 10 includes a front side plate 18 and a first air outlet flange 17. The front side plate 18 has a front air outlet 11, and the first air outlet flange 17 is located at the front air outlet 11. The first air guide is located inside the first air outlet flange 17, which provides installation space for the first air guide and also improves the installation stability of the first air guide.

[0097] When the first air guide includes a first sway vane 31, the multiple first sway vanes 31 are rotatably located at the first air outlet flange 17; the first air guide also includes a first connecting rod 32 and a second front drive mechanism 33, the first connecting rod 32 being connected to the multiple first sway vanes 31; the second front drive mechanism 33 is disposed on the front side plate 18 and located on one side of the first air outlet flange 17, the second front drive mechanism 33 being connected to the first connecting rod 32, the second front drive mechanism 33 being used to drive the first connecting rod 32 to drive the multiple first sway vanes 31 to rotate; wherein, one end of the first connecting rod 32 passes through the first air outlet flange 17 and is connected to the second front drive mechanism 33, the air outlet flange includes the first air outlet flange 17, and the second drive mechanism includes the second front drive mechanism 33.

[0098] In this embodiment, the front air outlet 11 is provided with a first air outlet flange 17, and multiple first swivel blades 31 are rotatably mounted inside the first air outlet flange 17. Compared with directly mounting the first swivel blades 31 at the opening of the front side plate 18, the first air outlet flange 17 can provide a ring support frame for the first swivel blades 31, improving the installation stability of the first swivel blades 31. A first connecting rod 32 connects multiple first swivel blades 31, and a second front drive mechanism 33 drives the first swivel blades 31 to rotate synchronously by driving the first connecting rod 32, so that the air outlet direction adjustment of the front air outlet 11 is more precise. The second front drive mechanism 33 is located on the front side plate 18 and on one side of the first air outlet flange 17. In this way, the second front drive mechanism 33 will not occupy the space inside the front air outlet 11 or the first air outlet flange 17, and can avoid the second drive mechanism affecting the air volume of the front air outlet 11. Moreover, the second front drive mechanism 33 is mounted on the front side plate 18, which makes it easier to disassemble and maintain the second front drive mechanism 33.

[0099] Optionally, the second front drive mechanism 33 includes a second motor 331 and a second bushing 332. One end of the second bushing 332 is connected to the output shaft of the second motor 331, and the other end of the second bushing 332 is connected to the first connecting rod 32. The other end of the second bushing is provided with a rotating buckle 333, and one end of the first connecting rod 32 is rotatably sleeved on the outside of the rotating buckle 333. The second bushing enables the second motor 331 to transmit power to the first connecting rod 32, improving the flexibility of the second front drive mechanism 33's placement.

[0100] Optionally, the first link 32 includes a link body 321 and a connecting rod connected together. The link body 321 is connected to a plurality of first sway vanes 31, and the connecting rod is connected to a second front drive mechanism 33. The connecting rod includes a first connecting rod 322 and a second connecting rod 323. One end of the first connecting rod 322 is connected to the link body 321, one end of the second connecting rod 323 is connected to the other end of the first connecting rod 322, and the other end of the second connecting rod 323 is connected to the second front drive mechanism 33. 22 is inclined towards the second front drive mechanism 33 in the direction from back to front, and the second connecting rod 323 extends towards the second front drive mechanism 33. In this way, the connecting rod is bent, so the installation position of the first swing blade 31 and the second front drive mechanism 33 is more flexible. It can not only install the first swing blade 31 in a set position, but also set the second front drive mechanism 33 on the outside of the front air outlet 11, so as to avoid the second front drive mechanism 33 blocking the air volume of the front air outlet 11, and also facilitate the disassembly and maintenance of the second front drive mechanism 33.

[0101] Optionally, the surface of the first oscillating blade 31 is provided with a first gentle breeze structure, and / or the surface of the second oscillating blade 41 is provided with a second gentle breeze structure. In this embodiment of the present disclosure, a gentle breeze structure 34 (hereinafter referred to as gentle breeze structure 34) is provided on the surface of the oscillating blades (for ease of description, the first oscillating blade 31 and the second oscillating blade 41 are collectively referred to as oscillating blades). The gentle breeze structure 34 can divide the airflow at the air outlet into multiple low-speed fine streams, reduce the airflow speed, avoid direct airflow, improve the efficiency of cooling or heating, and improve the user experience.

[0102] Optionally, such as Figure 18 As shown, the gentle breeze structure 34 includes grooves 341, and a single blade has multiple grooves 341, which are irregularly distributed. Optionally, the grooves 341 include spherical grooves 341. The irregularly distributed grooves 341 can divide the concentrated airflow into multiple irregular fine streams. This avoids the periodic airflow fluctuations that easily occur when the airflow passes through regularly distributed grooves 341 with a consistent rhythm. The irregular grooves 341 can break this regularity, making the airflow more turbulent and closer to the flow state of natural wind after being divided. In addition, the irregularly distributed grooves 341 can break the resonance condition, disperse the energy of the airflow impacting the grooves 341, and reduce noise.

[0103] Optionally, one or both walls in the thickness direction of the blades are provided with a gentle breeze structure 34.

[0104] Optionally, the first gentle breeze structure includes a first groove, and the first oscillating blade 31 is provided with multiple first grooves, which are irregularly distributed on the surface of the first oscillating blade 31. Optionally, the first groove is a spherical groove 341. Optionally, the second gentle breeze structure includes a second groove, and the second oscillating blade 41 is provided with multiple second grooves, which are irregularly distributed on the surface of the second oscillating blade 41. Optionally, the second groove is a spherical groove 341.

[0105] Optionally, the soft-wind structure 34 can also be a micro-protrusion, an arc-shaped guide groove, or a slit structure, etc. It can be understood that any structure capable of softening the airflow from the air outlet is an optional embodiment of this application.

[0106] Optionally, the length of the oscillating blade extends along the width of its corresponding air outlet, and the oscillating blade can rotate around its length. In this way, the oscillating blade can adjust the airflow direction along the length of the air outlet.

[0107] Optionally, the oscillating blades can open or close the air outlet. When the oscillating blades close the air outlet, two adjacent oscillating blades among the multiple oscillating blades come into contact (fit together or come close together) to close the air outlet.

[0108] Optionally, such as Figure 18 As shown, the oscillating blade includes a third end and a fourth end provided along the width direction of the oscillating blade. The third end is provided with a first protrusion structure 37, and the fourth end is provided with a second protrusion structure 38. When the oscillating blade closes the air outlet, the first protrusion structure 37 of one oscillating blade cooperates with the second protrusion mechanism of its adjacent oscillating blade to seal the connection between the two adjacent oscillating blades.

[0109] Optionally, the first protrusion structure 37 extends along the thickness direction of the blade, and the second protrusion structure 38 extends along the thickness direction of the blade. The extension direction of the first protrusion structure 37 is opposite to that of the second protrusion structure 38. When two adjacent blades are in contact, the first protrusion structure 37 and the second protrusion structure 38 are arranged sequentially along the width direction of the blade, which increases the sealing surface between the two blades and thus improves the sealing effect.

[0110] Optionally, the multiple blades of an air outlet include a first sub-blade 35 and a second sub-blade 36. When the multiple blades close the air outlet, one end of the first sub-blade 35 is located on the side of the second sub-blade 36 away from the air duct 13. That is, one end of the first sub-blade 35 facing the first wall of the air duct 13 is close to the other end of the second sub-blade 36 away from the second wall of the air duct 13. In this way, the multiple blades are partially stacked, which can further improve the closing effect when the blades close the air outlet, improve the sealing performance, and prevent air leakage.

[0111] Optionally, when multiple blades close the air outlet, the first protrusion structure 37 at one end of the first sub-blade 35 and the second protrusion structure 38 at the other end of the second sub-blade 36 are arranged sequentially along the length direction of the air outlet. In this way, the first sub-blade 35 and the second sub-blade 36 are stacked in the air outlet direction to improve the sealing effect of the connection. The first protrusion structure 37 and the second protrusion structure 38 seal in the length direction of the air outlet. In this way, a multi-bent connection surface is formed between the first sub-blade 35 and the second sub-blade 36, which improves the sealing effect.

[0112] Optionally, such as Figure 15 and Figure 17 As shown, the rotation angle of the oscillator blades ranges from 0° to 150°. This improves the airflow direction adjustable by the oscillator blades. Optionally, the oscillator blades are positioned at 0° when the air vent is closed. When the oscillator blades rotate to 90°, the width direction of the oscillator blades is perpendicular to the length direction of the air vent, at which point the airflow volume is at its maximum. When the oscillator blades are between 0° and 90°, the width direction of the oscillator blades is inclined towards the fifth end of the air vent, so that the airflow from the air vent is directed towards the fifth end. When the oscillator blades are between 90° and 150°, the width direction of the oscillator blades is inclined towards the sixth end of the air vent, so that the airflow from the air vent is directed towards the sixth end. The air vent includes the fifth and sixth ends, which are positioned along the length direction. This allows the oscillator blades to increase the airflow angle of the air vent, further enhancing the airflow patterns and versatility of the indoor unit. Optionally, the first pendulum 31 and / or the second pendulum 41 include the aforementioned first sub-pendulum 35 and second sub-pendulum 36, and also have the features of the aforementioned first sub-pendulum 35 and second sub-pendulum 36, which will not be repeated here. Optionally, the first pendulum 31 and / or the second pendulum 41 are provided with the aforementioned first protrusion structure 37 and second protrusion structure 38, which will not be repeated here.

[0113] Optionally, the first air guide includes a first air guide plate, which is movably disposed at the front air outlet 11 for opening or closing the front air outlet 11.

[0114] Optionally, such as Figure 11 and Figure 12 As shown, the second air guide includes a second air guide plate 44, which is movably disposed at the lower air outlet 12 and is used to open or close the lower air outlet 12.

[0115] In this embodiment of the disclosure, the front air outlet 11 and / or the lower air outlet 12 are controlled by air guide plates (for ease of description, the first air guide plate and the second air guide plate 44 are collectively referred to as air guide plates) to control their opening and closing. The air guide plates have a simple structure, low cost, good sealing effect, low energy consumption, and stable structure.

[0116] Optionally, such as Figure 12As shown, when the second air guide includes the second air guide plate 44, both ends of the second air guide plate 44 in the length direction are rotatably connected to the two side walls in the length direction of the clearance groove.

[0117] In this embodiment, the sidewall of the drainage groove of the water tray 50 directly serves as the rotational support for the second air guide plate 44, eliminating the need for an additional air guide plate bracket within the air duct 13. This avoids the air guide plate bracket obstructing airflow and ensures the air delivery efficiency of the lower air outlet 12. Furthermore, the second air guide plate 44, when closed, ensures a tight seal on the lower air outlet 12, preventing dust from entering the air duct 13 and the water tray 50, thus preventing the growth of bacteria in the condensate within the water tray 50.

[0118] Both ends of the second air guide plate 44 along its length are rotatably connected to the two side walls along the length of the clearance groove. This means the second air guide plate 44 can rotate around its length to adjust the airflow volume and direction of the lower air outlet 12. When the second air guide plate 44 is in the closed position, it closes the lower air outlet 12. When it is in the air outlet position, it is tilted relative to the lower air outlet 12 to allow airflow. Furthermore, the airflow direction of the lower air outlet 12 can be adjusted by changing the rotation angle of the second air guide plate 44.

[0119] Optionally, the two ends of the second air guide plate 44 along its length direction are rotatably connected to the two side walls along the length direction of the clearance groove via the second rotating shaft 46 and the second limiting groove 45. A bearing and a bushing are provided between the second rotating shaft 46 and the second limiting groove 45 to reduce the connecting friction between the second rotating shaft 46 and the second limiting groove 45 and improve the smoothness of rotation.

[0120] Optionally, the second limiting slot 45 is provided with a second release port 241, and the rotating shaft 23 can be released from the second limiting slot 45 through the second release port 241 to realize the disassembly of the second air guide plate 44.

[0121] Optionally, the second air guide plate 44 is detachably connected to the housing 10. The second air guide plate 44 can also be detached in other ways, such as by screws or pins.

[0122] Optionally, the surface of the air guide plate is provided with a second airflow guiding structure, which can guide the airflow passing through the air guide plate, improve air outlet efficiency, and reduce noise. Optionally, the second airflow guiding structure can be a rib, groove, protrusion, etc.

[0123] Optionally, the surface of the first air guide plate is provided with a third soft-wind structure. Optionally, the surface of the second air guide plate 44 is provided with a fourth soft-wind structure. The third and fourth soft-wind structures can be the aforementioned grooves, micro-protrusions, arc-shaped guide channels, or slit structures.

[0124] In some alternative embodiments, the front air outlet 11 is provided with a plurality of first sway vanes 31, the lower air outlet 12 is movably disposed on the second air guide plate 44, and the air guide plate 20 is located in the air duct 13.

[0125] In this embodiment, the lower air outlet 12 is located at the bottom of the indoor unit and typically emits air during heating. The lower air outlet 12 is equipped with a second air guide plate 44. When the second air guide plate 44 is open, the airflow from the lower air outlet 12 is larger, allowing hot air to be concentrated and delivered downwards. Due to the lower density of the hot airflow, it can quickly circulate vertically within the space, achieving rapid heating. The front air outlet 11 is equipped with multiple first sway vanes 31. When the indoor unit is cooling, the front air outlet 11 needs to be opened. The first sway vanes 31 ensure sufficient airflow from the front air outlet 11 and also provide guidance, increasing the air delivery distance, airflow speed, and overall cooling efficiency. Furthermore, the adjustment of the first sway vanes 31 prevents cold air from blowing directly on the user. Additionally, when both the front air outlet 11 and the lower air outlet 12 are emitting air, the first sway vanes 31 on the front air outlet 11 can rotate to disturb the airflow, achieving rapid heat exchange.

[0126] In some alternative embodiments, such as Figures 12 to 14 As shown, the water receiving tray 50 includes a water receiving section 51 and a flow guiding section 52: the water receiving section 51 is located below the heat exchanger 15; the flow guiding section 52 is located at one end of the water receiving section 51 and on the air outlet side of the heat exchanger 15; wherein, the flow guiding section 52 is constructed with a combing structure 53, which is used to comb the airflow flowing out of the heat exchanger 15. The flow guiding section 52 of the water receiving tray 50 on the air outlet side of the heat exchanger 15 is provided with a combing structure 53, which can comb the airflow flowing out of the heat exchanger 15, organize the turbulent airflow into a more stable and orderly airflow, reduce airflow disturbance, and improve the smoothness of air delivery. In addition, the combing structure 53 can reduce the resistance passing through the area of ​​the water receiving tray 50, reduce airflow loss, and ensure air delivery efficiency. In this way, the airflow flowing out of the heat exchanger 15 can flow more smoothly to the front air outlet 11 and / or the lower air outlet 12.

[0127] Optionally, the guide plate 20 is located on the air outlet side of the combing structure 53, so that the airflow from the bottom of the heat exchanger 15 and the water receiving pan 50 can flow to the guide plate 20 under the guidance of the combing structure 53, thereby increasing the airflow of the guide plate 20 and reducing airflow loss.

[0128] Optionally, the water receiving part is provided with a drain outlet for draining water from the water receiving part into the water receiving tray.

[0129] Optionally, the combing structure 53 includes combing ribs that are inclined upwards in a direction away from the water receiving part 51. The combing ribs can guide the airflow from the water receiving part 51 and the bottom of the heat exchanger 15 upwards, towards the middle of the air duct 13 and the guide plate 20, reducing the loss of airflow flowing through the water receiving pan 50 and increasing the airflow diverted by the guide plate 20, thus ensuring the airflow regulation function of the guide plate 20.

[0130] Optionally, multiple flow guides are provided, spaced apart along the length of the guide section 52. Multiple flow guides enhance the flow guiding effect along the length of the guide section 52, improving the uniformity of flow guiding along the length. Here, the length of the guide section 52 coincides with the length of the duct 13.

[0131] Optionally, the height of the comb ribs is 0.5~1.5mm. Within this range, the height of the comb ribs ensures that they effectively separate the airflow, preventing the airflow from overrunning the ribs and causing combing failure, while also avoiding excessive height that would increase airflow resistance.

[0132] Optionally, the width of the comb ribs is 1~2mm. A width within this range ensures the structural stability of the comb ribs and reduces the area obstructing airflow.

[0133] Optionally, the distance between two adjacent comb ribs is 20-40 mm. A distance of less than 20 mm between two adjacent comb ribs will result in a narrow airflow channel and a sharp increase in resistance, while a distance of more than 40 mm between two adjacent comb ribs will result in combing blind zones. The distance between two adjacent comb ribs within the aforementioned range can improve the uniformity of airflow combing and ensure the efficiency of airflow.

[0134] Optionally, such as Figure 13 As shown, the flow guide 52 is provided with a pressure relief channel 533, which connects the outside of the comb structure 53 and the water receiving tray 50. The pressure relief channel 533 is used to relieve pressure on the airflow flowing through the flow guide 52. Here, the pressure relief channel 533 can reduce the airflow pressure at the comb structure 53 and reduce noise.

[0135] Optionally, the flow guide 52 includes a comb plate 54, a first pressure relief plate 541, and a second pressure relief plate 542. The comb plate 54 is connected to the water receiving part 51 and is inclined upward in a direction away from the water receiving part 51. Combing ribs are provided on the comb plate 54. The first pressure relief plate 541 is provided at the end of the comb plate 54 away from the water receiving part 51 and extends downward. The second pressure relief plate 542 is provided below the comb plate 54 and is spaced apart from the first pressure relief plate 541, forming a pressure relief channel 533 with the first pressure relief plate 541. The comb plate 54 is provided with pressure relief holes 532, which are connected to the pressure relief channel 533. When the airflow passes through the combing ribs, a local high-pressure area is easily formed inside the comb structure 53, resulting in airflow turbulence and increased noise. The pressure relief hole 532 and pressure relief channel 533 provided in the comb plate 54 can guide the high-pressure airflow to the outside of the water receiving tray 50, reduce the pressure difference inside the comb structure 53, reduce airflow turbulence, reduce outlet pressure, and reduce noise.

[0136] Optionally, the pressure relief hole 532 is located at the top of the comb plate 54, and between two adjacent comb ribs. The pressure relief hole 532, located at the top of the comb plate 54, can relieve pressure on the airflow at the highest pressure point at the end of the comb rib, improving the pressure relief effect. Furthermore, the location of the pressure relief hole 532 at the top of the comb plate 54 also prevents it from being blocked by water in the water receiving tray 50.

[0137] Optionally, the lower end of the pressure relief channel 533 is provided with a bent channel that extends away from the water receiving part 51 to guide the airflow in the pressure relief channel 533 away from the water receiving part 51. The bent channel extends the length of the pressure relief channel 533, reduces the flow velocity in the pressure relief channel 533, reduces the noise of pressure relief in the pressure relief channel 533, and also avoids interference with the water receiving part 51.

[0138] Optionally, such as Figure 2 As shown, the outlet of the pressure relief channel is connected to the lower air outlet to increase the pressure relief speed of the pressure relief channel.

[0139] Optionally, the clearance groove is located on the side of the guide portion 52 away from the water receiving portion 51. The water receiving tray 50 also includes a first extension portion 55 and a second extension portion 56. The first extension portion 55 and the second extension portion 56 are respectively connected to the two ends of the guide portion 52 in the length direction and extend in a direction away from the water receiving portion 51. The first extension portion 55, the second extension portion 56 and the guide portion 52 define the clearance groove.

[0140] Optionally, the first extension 55 and the second extension 56 are two sidewalls in the length direction of the clearance groove, and the second air guide 40 is disposed on the first extension 55 and the second extension 56.

[0141] Optionally, when a second air guide plate 44 is provided at the lower air outlet 12, the two ends of the second air guide plate 44 in the length direction are respectively rotatably connected to the first extension 55 and the second extension 56.

[0142] Optionally, the number of guide vanes can be one or more. When there is only one guide vane, it can move between a first position and a second position. When there are multiple guide vanes, they can work together to adjust the airflow into the forward and downward air outlets within the duct.

[0143] In some alternative embodiments, such as Figures 9 to 22 As shown, where, Figure 22 and Figure 21 In the diagram, dashed arrows indicate the airflow direction towards the front air outlet, and solid arrows indicate the airflow direction towards the lower air outlet. The indoor unit includes a housing 10 and a baffle assembly. The housing 10 defines an air duct 13 with a front air outlet 11 and a lower air outlet 12. The baffle assembly is located within the air duct 13 and includes multiple baffles 20, each including a first baffle 25 and a second baffle 26. The first baffle 25 and the second baffle 26 cooperate to adjust the airflow towards the front air outlet 11 and the lower air outlet 12. The aforementioned baffles 20 include the first baffle 25 and the second baffle 26.

[0144] The indoor unit of this embodiment can achieve bidirectional airflow by setting a front air outlet 11 and a lower air outlet 12. Through the cooperation of the first guide vane 25 and the second guide vane 26, the airflow ratio to the front air outlet 11 and the lower air outlet 12 can be flexibly adjusted, allowing air to be delivered forward or downward individually, or simultaneously in both directions, adapting to multi-area airflow needs. The dual guide vanes 20 can guide and control the airflow at the two outlets respectively, effectively improving the airflow uniformity in each area and enhancing the user experience.

[0145] Optionally, the lengths of the first guide vane 25 and the second guide vane 26 both extend along the length of the air duct 13; wherein the first guide vane 25 and the second guide vane 26 are arranged along the height of the air duct 13. The arrangement of the two guide vanes along the height of the air duct 13 increases the coverage area of ​​the guide vane assembly in the height direction of the air duct 13, further improving the airflow diversion effect of the guide vane assembly, thereby maximizing the diversion of airflow within the air duct 13.

[0146] Optionally, the height of the top of the second guide vane 26 is less than the height of the top of the front air outlet 11, and the height of the lower end of the first guide vane 25 is greater than the height of the top of the second guide vane 26. In this way, the movement of the first guide vane 25 and the second guide vane 26 will not interfere with each other, and the influence of the second guide vane 26 on the airflow of the front air outlet 11 can be reduced or avoided.

[0147] Optionally, the height of the top of the second deflector 26 is less than or equal to the height of the middle of the front air outlet 11, in order to further reduce the impact on the air volume of the front air outlet 11.

[0148] Optionally, both the first guide vane 25 and the second guide vane 26 are rotatably disposed within the air duct 13, and both the first guide vane 25 and the second guide vane 26 can rotate around their length. The ability of both the first guide vane 25 and the second guide vane 26 to rotate around their length allows for more flexible rotation angles. Furthermore, continuous angle adjustment is possible. Compared to sliding or other types of movement, the movement of the first guide vane 25 and the second guide vane 26 is more precise, further improving the accuracy of the two guide vanes 20 in adjusting airflow and direction.

[0149] Optionally, the first guide vane 25 and / or the guide vane 20 are detachably connected to the housing 10. It is understood that the driving and disassembly methods of the first guide vane 25 and / or the second guide vane 26 are the same as those of the aforementioned guide vane 20, and will not be described again here.

[0150] Optionally, the first guide vane 25 can move between a third position and a fourth position. When the first guide vane 25 is in the third position, it avoids the front air outlet 11 so that the airflow in the air duct 13 flows to the front air outlet 11. When the first guide vane 25 is in the fourth position, it blocks the airflow in the air duct 13 from flowing to the front air outlet 11. The second guide vane 26 can move between a fifth position and a sixth position. When the second guide vane 26 is in the fifth position, it blocks the airflow in the air duct 13 from flowing to the downward air outlet 12. When the second guide vane 26 is in the sixth position, it avoids the downward air outlet 12 so that the airflow in the air duct 13 flows to the downward air outlet 12.

[0151] In this embodiment, when the first guide plate 25 is in the third position, the front air outlet 11 is unobstructed, allowing unobstructed airflow within the duct 13 to flow towards the front air outlet 11. When the first guide plate 25 is in the fourth position, it physically blocks the airflow, preventing it from flowing towards the front air outlet 11. Similarly, when the second guide plate 26 is in the sixth position, the lower air outlet 12 is unobstructed, allowing unobstructed airflow within the duct 13 to flow towards the lower air outlet 12. When the second guide plate 26 is in the fifth position, it physically blocks the airflow, preventing it from flowing towards the lower air outlet 12. Both the first guide plate 25 and the second guide plate 26 can move between positions that avoid their corresponding air outlets and positions that block their corresponding air outlets, further improving the flexibility and precision of the guide plate assembly in adjusting the airflow of the indoor unit.

[0152] Optionally, such as Figure 19 As shown, when the first guide plate 25 is in the third position and the second guide plate 26 is in the fifth position, the airflow in the air duct 13 flows towards the front air outlet 11. At this time, the first guide plate 25 avoids the front air outlet 11, and the second guide plate 26 blocks the lower air outlet 12, so that the airflow in the air duct 13 flows towards the front air outlet 11.

[0153] Optionally, such as Figure 20 As shown, when the first guide plate 25 is in the fourth position and the second guide plate 26 is in the sixth position, the airflow in the air duct 13 flows downward to the air outlet 12. At this time, the first guide plate 25 blocks the front air outlet 11, and the second guide plate 26 opens the lower air outlet 12 so that the airflow in the air duct 13 flows downward to the air outlet 12.

[0154] Optionally, such as Figure 21 As shown, when the first guide plate 25 is in the third position and the second guide plate 26 is in the sixth position, the airflow in the duct 13 flows to the front air outlet 11 and the lower air outlet 12 respectively. At this time, the first guide plate 25 and the second guide plate 26 avoid the front air outlet 11 and the lower air outlet 12 respectively, so that the airflow in the duct 13 can flow to the front air outlet 11 and the lower air outlet 12 simultaneously.

[0155] Optionally, the rotation angle of the first guide vane 25 from the third position to the fourth position includes 20°~90°, or 50°~70°. Optionally, the rotation angle of the second guide vane 26 from the fifth position to the sixth position includes 30°~90°, or 50°~70°. Since the rotation angles of the first guide vane 25 and the second guide vane 26 are within the above ranges, the first guide vane 25 and the second guide vane 26 only need to rotate a certain angle to switch positions, achieving different airflow effects. The structure is simple, easy to operate, and has good stability.

[0156] In practical applications, the rotation angle of the first guide plate 25 and the rotation angle of the second guide plate 26 can be set according to the size of the first guide plate 25 and the second guide plate 26, as well as the size of the front air outlet 11 and the lower air outlet 12. The angles that can avoid and block the air outlets are all optional embodiments of this application.

[0157] Optionally, when the first guide vane 25 is in the third position, the angle between the first guide vane 25 and the axis of the front air outlet 11 is less than or equal to the second set angle. In this way, the first guide vane 25 is parallel or approximately parallel to the axis of the front air outlet 11, so that the first guide vane 20 can avoid the front air outlet 11, without affecting the airflow from the front air outlet 11, and without affecting the airflow to the lower air outlet 12.

[0158] Optionally, when the first deflector 25 is in the third position, the first deflector 25 is positioned above the front air outlet 11. This allows for more complete avoidance of the front air outlet 11.

[0159] Optionally, when the first guide vane 25 is in the third position, the angle between the first guide vane 25 and the axis of the front air outlet 11 is 0° to 20°. Here, the first guide vane 25 can be straight or curved. When the first guide vane 25 is curved, the angle between the first guide vane 25 and the axis of the front air outlet 11 refers to the angle between the tangent in the width direction of the first guide vane 25 and the axis of the front air outlet 11.

[0160] Optionally, when the first guide vane 25 is in the fourth position, the angle between the first guide vane 25 and the axis of the front air outlet 11 is greater than the second set angle. In this way, the first guide vane 25 blocks the airflow within the duct 13 from flowing towards the front air outlet 11, positioned between the heat exchange assembly and the front air outlet 11. Optionally, the second set angle includes 5°~45°, 5°~30°, or 5°~20°.

[0161] Optionally, when the first guide vane 25 is in the fourth position, the first guide vane 25 extends along the height direction within the air duct 13 or tilts downwards or upwards in a direction from back to front. In this way, the first guide vane 25 blocks the airflow within the air duct 13 from flowing towards the front air outlet 11, thus preventing the airflow from reaching the front air outlet 11. Optionally, when the first guide vane 25 is in the fourth position, the angle between the first guide vane 25 and the axis of the front air outlet 11 is 20°~90° or 30°~90°.

[0162] Optionally, when the second guide plate 26 is in the fifth position, its lower end is located behind (inlet side) of the lower air outlet 12 and extends along the height direction of the air duct 13. In this way, the second guide plate 26 blocks the air inlet side of the lower air outlet 12, preventing the airflow from the heat exchange assembly from flowing down to the lower air outlet 12. The second guide plate 26 extending along the height direction of the air duct 13 means that the first guide plate 25 extends in the same direction as the air duct 13, or that the first guide plate 25 extends in a substantially consistent direction with the air duct 13.

[0163] Optionally, when the second guide vane 26 is in the fifth position, the second guide vane 26 is tilted upward in the direction from back to front. This increases the length of the second guide vane 26, and the projection of the second guide vane 26 from top to bottom falls into the lower air outlet 12. The second guide vane 26 can not only block the airflow from the rear of the lower air outlet 12 to the lower air outlet 12, but also block the airflow from the upper side of the lower air outlet 12 to the lower air outlet 12.

[0164] Optionally, when the second guide plate 26 is in the sixth position, the lower end of the second guide plate 26 is located in front of the lower air outlet 12 (air outlet side). In this way, the second guide plate 26 is located on the air outlet side of the lower air outlet 12, which can completely avoid the lower air outlet 12, so as to ensure that the airflow from the heat exchange component flows to the lower air outlet 12 and ensure the airflow of the lower air outlet 12.

[0165] Optionally, when the second guide vane 26 is in the sixth position, the second guide vane 26 is tilted downwards from back to front. This ensures that the second guide vane 26 avoids the lower air outlet 12 to the greatest extent possible while maintaining the rotational position of the second guide vane 26.

[0166] Optionally, when the first guide vane 25 is in the third position, the second guide vane 26 is configured to adjust the airflow to the front air outlet 11 and the lower air outlet 12 by moving between the fifth and sixth positions. The first guide vane 25 avoids the front air outlet 11, and the second guide vane 26, by moving between the fifth and sixth positions, can adjust the area of ​​the lower air outlet 12 on the front and rear sides of the second guide vane 26. In this way, the airflow on the front side of the second guide vane 26 needs to bypass the second guide vane 26 to flow into the lower air outlet 12, resulting in a smaller airflow. The airflow on the rear side of the second guide vane 26 can flow directly into the lower air outlet 12, reducing the airflow into the lower air outlet 12 and increasing the airflow to the front air outlet 11. This allows for the adjustment of the airflow to the front air outlet 11 and the lower air outlet 12.

[0167] Optionally, when the second deflector 26 is in the fifth position, the first deflector 25 is configured to move between the third and fourth positions to regulate the airflow to the forward air outlet 11 and the lower air outlet 12.

[0168] Optionally, when the first guide vane 25 moves between the third and fourth positions and the second guide vane 26 is in the fifth and sixth positions, the first guide vane 25 and the second guide vane 26 are configured to jointly regulate the airflow to the forward air outlet 11 and the downward air outlet 12.

[0169] Optionally, the second guide vane 26 can also move to a seventh position, which is between the fifth and sixth positions. When the second guide vane 26 is in the seventh position, its lower end corresponds to the middle of the lower air outlet 12. In this way, airflow flows to the lower air outlet 12 from the rear side of the second guide vane 26, while the airflow from the front side of the second guide vane 26 is reduced or eliminated due to the obstruction of the second guide vane 26.

[0170] For example, such as Figure 22 As shown, when the first guide vane 25 is in the third position and the second guide vane 26 is in the eighth position, the airflow to the forward air outlet 11 and the airflow to the downward air outlet 12 are the same. The seventh position includes the eighth position.

[0171] Optionally, the first guide plate 25 and / or the second guide plate 26 are provided with the aforementioned guiding structure, and the guiding structure 21 is used to guide the airflow within the air duct 13. Here, the structure and effect of the guiding structure 21 are the same as described above, and will not be repeated here.

[0172] In some alternative embodiments, the third position of the first guide plate 25 may be the same as or different from the first position of the aforementioned guide plate, and the fourth position of the first guide plate may be the same as or different from the second position of the aforementioned guide plate.

[0173] Optionally, the controller is electrically connected to both the first guide vane 25 and the second guide vane 26, and the controller is configured to control the movement of the first guide vane 25 and the second guide vane 26.

[0174] Alternatively, the indoor unit may include a ducted air conditioner, a recessed air conditioner, or a wall-mounted air conditioner.

[0175] This disclosure also provides an air conditioner, which includes the indoor unit of any of the above embodiments. Therefore, the beneficial effects of having the indoor unit of any of the above embodiments will not be elaborated further here.
