Description

Technical Field

[0001] This invention relates to the field of air intake and exhaust control for panel air conditioners, and more particularly to a control device, method, and air conditioner for air intake and exhaust control. Background Technology

[0002] The existing air conditioner outlets rely on air guide vanes to adjust the airflow direction. However, these vanes can only adjust the airflow direction and, due to their size limitations, cannot increase the air delivery distance.

[0003] In existing technologies, increasing the air delivery distance requires the use of additional air delivery panels. During the air conditioning cooling or heating process, the air delivery panels are installed on both sides of the air outlet to help increase the air delivery distance. When the air conditioner stops running, the air delivery panels are then disassembled and stored. This method not only requires frequent disassembly and installation, increasing the waste of human resources, but even without disassembly, the air delivery panels cannot be effectively stored. When the air conditioner is off, the air delivery panels still installed at the air outlet occupy a large area, which is not conducive to the normal life and work of people indoors. Summary of the Invention

[0004] This invention aims to at least partially solve one of the problems in related technologies. Therefore, the object of this invention is to provide a control device, method, and air conditioner for air intake and exhaust, which simultaneously adjusts the air outlet direction and distance using a rotatable first and second air guide plate.

[0005] To achieve the above objectives, this application adopts the following technical solution: a control device for air conditioning intake and exhaust, including a panel located on the front side of the air conditioner, and an air inlet and an air outlet located at the top and bottom of the air conditioner, and also including a first air guide plate and a second air guide plate, wherein the fixed end of the first air guide plate is rotatably connected to the side of the air outlet near the panel, and the movable end of the first air guide plate can rotate around the fixed end toward the direction of approaching or moving away from the panel.

[0006] The fixed end of the second air guide plate is rotatably connected to the side of the air outlet away from the panel, and the movable end of the second air guide plate can rotate around the fixed end in a direction closer to or farther from the panel.

[0007] Furthermore, the fixed end of the first air guide plate is rotatably connected to the first rotating shaft, and the fixed end of the second air guide plate is rotatably connected to the second rotating shaft via a connecting rod.

[0008] Furthermore, the air conditioner has a front sidewall, the fixed end of the panel is rotatably connected to the side of the air inlet, and the movable end of the panel can rotate around the fixed end toward the front sidewall or away from it.

[0009] Furthermore, the fixed end of the panel is rotatably connected to the third rotating shaft.

[0010] Furthermore, the panel is provided with an air inlet hole and an air inlet baffle at one end near the air outlet, and the air inlet baffle rotates to cover the air inlet hole; the air inlet baffle is connected to the air inlet drive component through a linkage mechanism.

[0011] Furthermore, when the moving end of the first air guide plate comes into contact with the panel, the air inlet baffle does not overlap with the first air guide plate.

[0012] Furthermore, when the moving end of the second air guide plate comes into contact with the panel, the second air guide plate covers the air inlet baffle.

[0013] Furthermore, when the air conditioner is off, the moving end of the second air guide plate abuts against the panel, the moving end of the first air guide plate abuts against the panel, and the air inlet baffle covers the surface of the air inlet hole.

[0014] When the air conditioner is in cooling mode, the moving end of the second air guide plate rotates away from the panel, so that the air outlet blows air upwards; the moving end of the first air guide plate abuts against the panel, and the air inlet baffle rotates away from the air inlet hole.

[0015] When the air conditioner is in heating mode, the moving end of the second air guide plate rotates away from the panel, and the moving end of the first air guide plate rotates away from the panel, so that the air outlet blows downwards; the air inlet baffle rotates away from the air inlet hole.

[0016] A method for controlling the intake and exhaust of air in an air conditioning system, as described above, includes:

[0017] When the air conditioner is off, the moving end of the second air guide plate abuts against the panel, and the moving end of the first air guide plate abuts against the panel.

[0018] When the air conditioner is in cooling mode, the moving end of the second air guide plate rotates away from the panel, so that the air outlet blows air upwards, and the moving end of the first air guide plate abuts against the panel.

[0019] When the air conditioner is in heating mode, the moving end of the second air guide plate rotates away from the panel, and the moving end of the first air guide plate rotates away from the panel, so that the air outlet blows downwards.

[0020] An air conditioner includes a control device for air intake and exhaust as described above.

[0021] Compared with the prior art, the technical solution provided in this application has the following advantages: In this application, the fixed end of the first air guide plate is rotatably connected to the side of the air outlet near the panel, and the moving end of the first air guide plate can rotate around the fixed end in a direction closer to or farther from the panel; the fixed end of the second air guide plate is rotatably connected to the side of the air outlet away from the panel, and the moving end of the second air guide plate can rotate around the fixed end in a direction closer to or farther from the panel; both the first and second air guide plates are rotatably connected to both sides of the air outlet. When the air conditioner is off, the moving end of the second air guide plate abuts against the panel, and the moving end of the first air guide plate... The end abuts against the panel; it can block the air outlet and store the first and second air guide plates; when the air conditioner is cooling or heating, the second air guide plate opens, exposing the air outlet. At the same time, the rotation angle of the first and second air guide plates can determine the air outlet direction, and the rotation position of the first and second air guide plates can determine the air delivery distance. This application uses the rotatable first and second air guide plates to simultaneously adjust the air outlet direction and air delivery distance, improving the adjustment efficiency of the air conditioner's air outlet direction and air delivery distance, and enabling the effective storage of the first and second air guide plates when the unit is off.

[0033] Example 1

[0034] Please see Figures 1-4 This application provides a control device for air conditioning intake and exhaust, including a panel 11 located on the front side of the air conditioner, and an air inlet 2 and an air outlet 3 located at the top and bottom of the air conditioner. It also includes a first air guide plate 14 and a second air guide plate 16. The fixed end of the first air guide plate 14 is rotatably connected to the side of the air outlet 3 near the panel 11, and the movable end of the first air guide plate 14 can rotate around the fixed end in a direction closer to or away from the panel 11. The fixed end of the second air guide plate 16 is rotatably connected to the side of the air outlet 3 away from the panel 11, and the movable end of the second air guide plate 16 can rotate around the fixed end in a direction closer to or away from the panel 11.

[0035] In this application, the first air guide plate 14 and the second air guide plate 16 are rotatably connected to both sides of the air outlet 3. When the air conditioner is off, the moving end of the second air guide plate 16 abuts against the panel 11, and the moving end of the first air guide plate 14 abuts against the panel 11. This can achieve the blocking of the air outlet 3 and the storage of the first air guide plate 14 and the second air guide plate 16. When the air conditioner is cooling or heating, the second air guide plate 16 opens, exposing the air outlet 3. At the same time, the rotation angle of the first air guide plate 14 and the second air guide plate 16 can determine the air outlet direction, and the rotation position of the first air guide plate 14 and the second air guide plate 16 can determine the air delivery distance. This application uses the rotatable first air guide plate 14 and the second air guide plate 16 to simultaneously adjust the air outlet direction and air delivery distance, improving the adjustment efficiency of the air conditioner's air outlet direction and air delivery distance, and enabling the effective storage of the first air guide plate 14 and the second air guide plate 16 when the air conditioner is off.

[0036] Example 2

[0037] This application provides a control device for air intake and exhaust of an air conditioner, including a panel 11 located on the front side of the air conditioner, and an air inlet 2 and an air outlet 3 located at the top and bottom of the air conditioner. The air conditioner can be a wall-mounted air conditioner, with its rear side mounted on the wall. The air inlet 2 is located at the top of the air conditioner, and the air outlet 3 is located at the bottom of the air conditioner. A fan 4 and other components are installed inside the air conditioner's internal cavity.

[0038] This application provides a first air guide plate 14 and a second air guide plate 16 at the air outlet 3. The fixed end of the first air guide plate 14 is rotatably connected to the side of the air outlet 3 near the panel 11, and the movable end of the first air guide plate 14 can rotate around the fixed end in a direction closer to or away from the panel 11. Specifically, the fixed end of the first air guide plate 14 is rotatably connected in a first rotating shaft 15, which is fixed to the side of the air outlet 3 near the panel 11. The extension direction of the first rotating shaft 15 is parallel to the intersection line of the panel 11 and the air outlet 3. The first rotating shaft 15 is connected to a first driving component, which is communicatively connected to an air conditioning controller. The first driving component receives instructions from the air conditioning controller and drives the first rotating shaft 15 to rotate, thereby enabling the movable end of the first air guide plate 14 to rotate around the fixed end in a direction closer to or away from the panel 11.

[0039] The fixed end of the second air guide plate 16 is rotatably connected to the side of the air outlet 3 away from the panel 11. The movable end of the second air guide plate 16 can rotate around the fixed end in a direction closer to or further away from the panel 11. Specifically, the fixed end of the second air guide plate 16 is rotatably connected to the second rotating shaft 17 via a connecting rod 18. The second rotating shaft 17 is fixed to the side of the air outlet 3 away from the panel 11, that is, the side of the air outlet 3 closer to the rear sidewall. The extension direction of the second rotating shaft 17 is parallel to the intersection line of the rear sidewall and the air outlet 3. The second rotating shaft 17 is connected to the second driving component, which is communicatively connected to the air conditioning controller. The second driving component receives instructions from the air conditioning controller and drives the second rotating shaft 17 to rotate, thereby enabling the movable end of the second air guide plate 16 to rotate around the fixed end in a direction closer to or further away from the panel 11.

[0040] The panel 11 of this application has an air inlet hole and an air inlet baffle 12 at one end near the air outlet 3. The air inlet baffle 12 rotates to cover the air inlet hole. The air inlet baffle 12 is connected to the air inlet drive component through a linkage mechanism. The air inlet hole is a through hole opened in the panel 11. When the air inlet hole is covered by the air inlet baffle 12, it cannot allow air to enter. When the air inlet baffle 12 covering the air inlet hole is opened, the air inlet hole can be used as an air inlet 2, which together with the air inlet 2 located at the top of the air conditioner to increase the air intake volume of the air conditioner, thereby increasing the air output volume of the air conditioner.

[0041] The number of air inlet baffles 12 corresponds one-to-one with the air inlet holes. In order to facilitate the control of the air inlet baffles 12, the air inlet baffles 12 in this application are connected to the air inlet drive unit through a linkage mechanism. That is, the air inlet drive unit can simultaneously drive multiple air inlet baffles 12 to open or close synchronously. Closing means covering the air inlet holes, and opening means rotating relative to the air inlet holes.

[0042] like Figure 4As shown, taking three air intake baffles 12 as an example: the middle air intake baffle 12 is connected to the drive wheel 51, which is connected to the output end of the air intake drive component, such as a motor or cylinder. The drive wheel 51 meshes with the first driven wheel 52, and both are located on the side of the middle air intake baffle 12. The first driven wheel 52 meshes with the second driven wheels 53 and the third driven wheels 54 on the left and right sides, respectively. The second driven wheels 53 and 54 are located on the sides of the left and right air intake baffles 12. The second driven wheel 53 meshes with the second drive wheel 55, which is connected to the left air intake baffle 12. The third driven wheel 54 meshes with the third drive wheel 56, which is connected to the right air intake baffle 12. Similarly, when there are multiple air inlet baffles 12, a linkage mechanism can be formed by the meshing of driven wheels and driving wheels to ensure that when the air inlet drive component drives the driving wheel 51 to rotate, all driven wheels and driving wheels rotate synchronously, thereby achieving synchronous rotation of the air inlet baffles 12.

[0043] The air conditioner of this application has a front sidewall 1 on its front side. The fixed end of the panel 11 is rotatably connected to the side of the air inlet 2. The movable end of the panel 11 can rotate around the fixed end in a direction closer to or further away from the front sidewall 1. The panel 11 can be arc-shaped, and the specific arc structure can be designed according to the appearance of the air conditioner. When the air conditioner is not running, the panel 11 can be rotated to a position that fits against the front sidewall 1, which helps to reduce the floor space occupied by the air conditioner. When the air conditioner is running, the panel 11 can be slightly moved away from the front sidewall 1, which makes it easier for the air inlet baffle 12 in the panel 11 to open and increase the air inlet area. As a specific embodiment, the fixed end of the panel 11 is rotatably connected to a third rotating shaft 13, which is located at the connection between the top of the panel 11 and the upper side panel of the air conditioner.

[0044] In this application, the first air guide plate 14 and the second air guide plate 16 are both arc-shaped, specifically, they can be arc-shaped to match the shape of the panel 11. When the first air guide plate 14 and the second air guide plate 16 are rotated to abut against the panel 11, the first air guide plate 14 and the second air guide plate 16 can be completely attached to the panel 11, thus achieving effective storage of the first air guide plate 14 and the second air guide plate 16.

[0045] In this application, the first air guide plate 14 is shorter, the second air guide plate 16 is longer, and the air inlet baffle 12 is located on the lower side of the panel 11. When the first air guide plate 14 is attached to the panel 11, the first air guide plate 14 and the air inlet baffle 12 do not overlap, that is, the length of the first air guide plate 14 is less than the distance from the first rotating shaft 15 to the air inlet baffle 12. When the moving end of the second air guide plate 16 abuts against the panel 11, the second air guide plate 16 covers the air inlet baffle 12 and the first air guide plate 14. That is, the length of the first air guide plate 14 needs to be greater than the farthest distance from the first rotating shaft 15 to the baffle plus the width of the air outlet 3, to ensure that when the second air guide plate 16 is attached to the panel 11, the second air guide plate 16 can completely cover the first air guide plate 14 and the air inlet baffle 12.

[0046] The reason for designing the length difference between the first air guide plate 14, the second air guide plate 16, and the air inlet panel 11 in this application is that when the air conditioner stops operating, the air inlet baffle 12, the first air guide plate 14, and the second air guide plate 16 all need to be attached to the panel 11 for storage. At this time, the second air guide plate 16 can completely cover the first air guide plate 14 and the air inlet baffle 12, making the overall space of the air conditioning unit smaller. Furthermore, using a large second air guide plate 16 to fully cover the lower part of the panel 11 results in a neat and elegant appearance, which helps to improve the external image. At the same time, the first air guide plate 14 does not overlap with the air inlet baffle 12, ensuring that even when the first air guide plate 14 is attached to the panel 11 and the second air guide plate 16 is open, the air intake volume can still be increased.

[0047] In this application, when the air conditioner is off, the movable end of the second air guide plate 16 abuts against the panel 11, the movable end of the first air guide plate 14 abuts against the panel 11, and the air inlet baffle 12 covers the surface of the air inlet hole. At this time, the second air guide plate 16 can completely cover the first air guide plate 14 and the air inlet baffle 12, making the overall space of the air conditioning space smaller. Moreover, the use of a large second air guide plate 16 to fully cover the lower part of the panel 11 is neat and elegant, which helps to improve the external image.

[0048] When the air conditioner is in cooling mode, the moving end of the second air guide plate 16 rotates away from the panel 11, allowing the air outlet 3 to blow air upwards. The specific position of the second air guide plate 16 can be designed according to its curvature, ensuring that the end of the second air guide plate 16 forms an upward airflow channel with the air outlet 3. Furthermore, in this application, the second air guide plate 16 and the air outlet 3 together forming an upward airflow channel increases the air delivery distance of the air conditioner.

[0049] The movable end of the first air guide plate 14 abuts against the panel 11, and the air inlet baffle 12 rotates to a position away from the air inlet hole, so that the air inlet hole and the air inlet 2 can enter the air together, thereby increasing the air volume.

[0050] When the air conditioner is in heating mode, the moving end of the second air guide plate 16 rotates away from the panel 11, and the moving end of the first air guide plate 14 rotates away from the panel 11, so that the air outlet 3 blows air downwards. Specifically, the positions of the first air guide plate 14 and the second air guide plate 16 can be designed according to their respective curvatures to ensure that a downward airflow channel is formed at the first air guide plate 14, the second air guide plate 16, and the air outlet 3. At the same time, the downward airflow channel formed by the first air guide plate 14, the second air guide plate 16, and the air outlet 3 in this application can increase the air delivery distance of the air conditioner.

[0051] The air inlet baffle 12 is rotated to a position away from the air inlet hole, so that the air inlet hole and the air inlet 2 can be used together to increase the air volume.

[0052] Example 3

[0053] This application provides a method for controlling the air intake and exhaust of an air conditioner, comprising the following steps:

[0054] like Figure 1 As shown, when the air conditioner is off, the moving end of the second air guide plate 16 abuts against the panel 11, the moving end of the first air guide plate 14 abuts against the panel 11, and the air inlet baffle 12 covers the surface of the air inlet hole. At this time, the second air guide plate 16 can completely cover the first air guide plate 14 and the air inlet baffle 12, making the overall space of the air-conditioned space smaller. The use of a large second air guide plate 16 to fully cover the lower part of the panel 11 is neat and elegant, which helps to improve the external image.

[0055] like Figure 2 As shown, when the air conditioner is in cooling mode, the movable end of the second air guide plate 16 rotates away from the panel 11, specifically, it can be moved to a state where the front end of the second air guide plate 16 is tilted up by 20°. Here, 20° refers to the angle between the front end of the second air guide plate 16 and the horizontal direction being 20°. This allows the end of the second air guide plate 16 to form an upward airflow channel with the air outlet 3, causing the cold air to sink and contributing to effective indoor cooling. During the cooling phase, the movable end of the first air guide plate 14 abuts against the panel 11; no movement is required, and upward airflow can be achieved solely by relying on the second air guide plate 16. In this application, the second air guide plate 16 and the air outlet 3 together form an upward airflow channel, which can increase the air delivery distance of the air conditioner.

[0056] At the same time, the air conditioner controller controls the operation of the air intake drive, which causes the air intake baffle 12 to open, so that the air intake hole and the air inlet 2 can enter together, increasing the air intake volume, thereby increasing the air output volume and cooling efficiency.

[0057] like Figure 3As shown, when the air conditioner is in heating mode, the moving end of the second air guide plate 16 rotates away from the panel 11. Specifically, it can rotate counterclockwise until the front end of the second air guide plate 16 forms a 45° angle with the horizontal. The moving end of the first air guide plate 14 rotates away from the panel 11. Specifically, it can rotate counterclockwise until the front end of the first air guide plate 14 forms a 70° angle with the horizontal, ensuring that a downward airflow channel is formed at the first air guide plate 14, the second air guide plate 16, and the air outlet 3. In this application, the first air guide plate 14, the second air guide plate 16, and the air outlet 3 together form a downward airflow channel, which can increase the air delivery distance of the air conditioner.

[0058] At the same time, the air conditioner controller controls the operation of the air intake drive, which causes the air intake baffle 12 to open, so that the air intake hole and the air inlet 2 can enter together, increasing the air intake volume, thereby increasing the air output volume and cooling efficiency.

[0059] This application utilizes a rotatable first air guide plate 14 and a second air guide plate 16 to simultaneously adjust the air outlet direction and air outlet distance, thereby improving the adjustment efficiency of the air outlet direction and air outlet distance of the air conditioner, and enabling the effective storage of the first air guide plate 14 and the second air guide plate 16 when the unit is off. At the same time, this application utilizes the air inlet baffle 12 on the panel 11 to increase the air intake volume when the air conditioner is running, thereby increasing the air outlet volume and effectively improving the air intake and exhaust efficiency of the air conditioner.

[0060] This application also provides an air conditioner, including the control device for air intake and exhaust as described above.

It should be noted that those skilled in the art can freely combine the above technical features without departing from the concept of the present invention, and can also make several modifications and improvements, all of which fall within the protection scope of the present invention. Therefore, all equivalent transformations and modifications made with respect to the scope of the claims of the present invention should fall within the scope of the claims of the present invention.
