Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air handling equipment technology, and more specifically, to an air conditioner. Background Technology

[0002] In conventional central air conditioning systems, duct-type indoor units (i.e., recessed indoor units) are typically installed within the ceiling. These units usually utilize centrifugal fans and ductwork, with one air inlet and one air outlet. Air is typically drawn in from the bottom and exited from the side, using an engineered panel (i.e., an engineered grille) to guide and diffuse airflow, achieving cooling / heating functions. Engineered panels are popular due to their customizable length and width, and their ability to coordinate with home décor, making them the most common installation method. Some recessed indoor units also feature a bottom air outlet to address the issue of hot air not reaching the ground. However, these recessed units are prone to condensation during use, leading to a poor user experience. Utility Model Content

[0003] The technical problem to be solved by this application is to provide an air conditioner that helps to reduce the risk of condensation in the indoor unit of an embedded air conditioner, thereby improving the user experience.

[0004] This application provides an air conditioner, including at least one of a first electric control panel and a second electric control panel, and an embedded air conditioner indoor unit; the embedded air conditioner indoor unit includes a housing and a damper assembly, the housing having a side air outlet and a bottom air outlet; the damper assembly is connected to the housing and configured to control the opening and closing of the side air outlet and the bottom air outlet; the first electric control panel is located outside the embedded air conditioner indoor unit, the first electric control panel having a first vent corresponding to and communicating with the side air outlet and a first electric damper for controlling the opening and closing of the first vent; the second electric control panel is located outside the embedded air conditioner indoor unit, the second electric control panel having a second vent corresponding to and communicating with the bottom air outlet and a second electric damper for controlling the opening and closing of the second vent.

[0005] When the air conditioner includes a first electric control panel, the first electric damper and damper assembly are equivalent to having a double damper on the opposite side air outlet. The double damper provides better air insulation and heat preservation, helping to prevent condensation caused by the convergence of high and low temperature airflows inside and outside the embedded air conditioner indoor unit when the side air outlet is closed. When the air conditioner includes a second electric control panel, the second electric damper and damper assembly are equivalent to having a double damper on the lower air outlet. The double damper also provides better air insulation and heat preservation, helping to prevent condensation caused by the convergence of high and low temperature airflows inside and outside the embedded air conditioner indoor unit when the lower air outlet is closed. Therefore, the air conditioner in this solution, by including at least one of the first and second electric control panels, can reduce the risk of condensation in the embedded air conditioner indoor unit, thus improving the user experience.

[0021] in, Figure 1 and Figure 4 The two first air valves in the text refer to two positions of the first air valve. In this air outlet mode, the first air valve can be located at any position between these two positions, and does not mean that there are two first air valves. Detailed Implementation

[0022] The principles and features of this application are described below with reference to the accompanying drawings. The examples given are only for explaining this application and are not intended to limit the scope of this application.

[0023] like Figures 1 to 5As shown in the illustration, this application provides an air conditioner, including at least one of a first electric panel 2 and a second electric panel 3, and an embedded air conditioner indoor unit 1. The embedded air conditioner indoor unit 1 can be, but is not limited to, a duct-type indoor unit or a ceiling-mounted unit.

[0024] The recessed air conditioner indoor unit 1 includes a housing 10 and an air valve assembly. The housing 10 is provided with a side air outlet 11 and a bottom air outlet 12, such as... Figures 1 to 5 As shown. The air valve assembly is connected to the housing 10 and is configured to control the opening and closing of the side air outlet 11 and the lower air outlet 12.

[0025] like Figure 1 As shown, the first electric panel 2 is located outside the embedded air conditioner indoor unit 1. The first electric panel 2 is provided with a first ventilation opening 22 that is connected to the side air outlet 11 and a first electric damper 21 for controlling the opening and closing of the first ventilation opening 22.

[0026] like Figure 1 As shown, the second electric panel 3 is located outside the embedded air conditioner indoor unit 1. The second electric panel 3 is provided with a second vent 32 that is connected to the lower air outlet 12 and a second electric damper 31 for controlling the opening and closing of the second vent 32.

[0027] The air conditioner may include only one of the first electric panel 2 and the second electric panel 3. For example, it may include only the first electric panel 2 (in which case the start and stop of the side air outlet function requires the air valve assembly to cooperate with the first electric panel 2 for control), or it may include only the second electric panel 3 (in which case the start and stop of the bottom air outlet function requires the air valve assembly to cooperate with the second electric panel 3 for control), or it may include both (in which case the start and stop of the side air outlet function requires the air valve assembly to cooperate with the first electric panel 2 for control, and the start and stop of the bottom air outlet function requires the air valve assembly to cooperate with the second electric panel 3 for control).

[0028] The air conditioner provided in this embodiment has an embedded indoor unit 1 with a side air outlet 11 and a bottom air outlet 12. The side air outlet 11 can realize side air outlet (e.g., front air outlet) function, enabling airflow to be delivered over long distances; the bottom air outlet 12 can realize bottom air outlet function, which can solve the problem of blind air supply area below the embedded indoor unit 1, allowing hot air to reach the ground in heating mode, thereby improving the user experience. The air valve assembly can control the opening and closing of the side air outlet 11 and the bottom air outlet 12.

[0029] Furthermore, the recessed air conditioner indoor unit 1 can be used with a first electric panel 2 / second electric panel 3. After installation, the recessed air conditioner indoor unit 1 is hidden inside the ceiling 5. The first electric panel 2 / second electric panel 3 are embedded in the corresponding openings in the ceiling 5, connecting the air outlet of the recessed air conditioner indoor unit 1 with the external space of the ceiling 5, allowing the airflow output by the recessed air conditioner indoor unit 1 to be delivered to the external space of the ceiling 5. Since the first electric panel 2 is equipped with a first electric damper 21, it can automatically control the opening and closing of the first vent 22, thereby realizing the automatic start and stop of the side air outlet function without manual adjustment by the user, which is beneficial to improving the user experience. The second electric panel 3 is equipped with a second electric damper 31, which can automatically control the opening and closing of the second vent 32, thereby realizing the automatic start and stop of the bottom air outlet function without manual adjustment by the user, which is beneficial to improving the user experience. Furthermore, by controlling the air valve assembly and the first electric damper 21 / second electric damper 31, the side air outlet function and the bottom air outlet function can be used selectively or together, which enriches the air outlet modes of the air conditioner, expands the air supply range of the air conditioner, and helps to improve the user experience.

[0030] In addition, when the air conditioner is turned off, the first electric damper 21 and the second electric damper 31 can close the first vent 22 and the second vent 32, which can prevent external impurities or dirt from entering the embedded air conditioner indoor unit 1 or accumulating at the first vent 22 / second vent 32, which helps to keep the air outlet of the embedded air conditioner indoor unit 1 clean and hygienic.

[0031] Furthermore, when the air conditioner includes the first electric panel 2, the first electric damper 21 and the damper assembly are equivalent to providing a double damper for the side air outlet 11. The double damper provides better air insulation and heat preservation, which helps to prevent condensation caused by the convergence of high and low temperature airflows inside and outside the embedded air conditioner indoor unit 1 when the side air outlet 11 is closed. When the air conditioner includes the second electric panel 3, the second electric damper 31 and the damper assembly are equivalent to providing a double damper for the lower air outlet 12. The double damper provides better air insulation and heat preservation, which helps to prevent condensation caused by the convergence of high and low temperature airflows inside and outside the embedded air conditioner indoor unit 1 when the lower air outlet 12 is closed. Therefore, the air conditioner of this solution, by including at least one of the first electric panel 2 and the second electric panel 3, can reduce the risk of condensation in the embedded air conditioner indoor unit 1, which is beneficial to improving the user experience.

[0032] In some exemplary embodiments, the side air outlet 11 can be, but is not limited to, a front air outlet, discharging air forward. The first motorized panel 2 can include a first panel body 23, which has a first ventilation opening 22. The shape of the first ventilation opening 22 can be, but is not limited to, rectangular. A first motorized damper 21 is mounted on the first panel body 23. The second motorized panel 3 can include a second panel body 34, which has a second ventilation opening 32. The second motorized damper 31 is mounted on the second panel body 34. The shape of the second ventilation opening 32 can be, but is not limited to, rectangular. The motorized panel can also be called a 3D panel.

[0033] In some exemplary embodiments, such as Figures 1 to 5 As shown, the damper assembly includes a rotatable first damper 14 and a rotatable second damper 15. The side air outlet 11 includes a first sub-outlet 111 and a second sub-outlet 112, with the second sub-outlet 112 located below the first sub-outlet 111. The first damper 14 is located at the first sub-outlet 111 and is configured to control the opening and closing of the first sub-outlet 111. The rotation axis of the second damper 15 is located between the second sub-outlet 112 and the lower air outlet 12, and is configured to control the opening and closing of both the second sub-outlet 112 and the lower air outlet 12.

[0034] Therefore, the width of the side air outlet 11 is greater than the width of the bottom air outlet 12, and the opening and closing of the side air outlet 11 is jointly controlled by the first air valve 14 and the second air valve 15. The opening and closing of the bottom air outlet 12 is controlled by the second air valve 15. This design achieves both opening and closing control of the side air outlet 11 and the bottom air outlet 12, and the widths of the first air valve 14 and the second air valve 15 are relatively narrow, resulting in a compact structure. This reduces the space required for the rotation of the valve assembly and helps to reduce the size of the embedded air conditioner indoor unit 1.

[0035] Among them, such as Figures 1 to 5 As shown, the rotation axis of the second air valve 15 is located at the end of the width direction of the second air valve 15, so that the second air valve 15 can control the opening and closing of the second sub-air outlet 112 and the lower air outlet 12. The rotation axis of the first air valve 14 can be located at the end of the width direction of the first air valve 14 (e.g., Figures 1 to 5 (As shown), it can also be located in the middle of the width direction of the first air valve 14.

[0036] Of course, the first air valve 14 and the second air valve 15 can also be used to control the opening and closing of the side air outlet 11 and the lower air outlet 12, respectively. In this case, the widths of the side air outlet 11 and the lower air outlet 12 do not affect each other and can be set reasonably as needed. Alternatively, the opening and closing of the lower air outlet 12 can be controlled by multiple air valves.

[0037] In some exemplary embodiments, the first air valve 14 is configured in the sixth position of closing the first sub-air outlet 111 (e.g., Figure 3 and Figure 5 (as shown) and the seventh position of opening the first sub-vent 111 (as shown) Figure 4 The second air valve 15 is configured to rotate back and forth between the lower air outlet 12 and the second sub-air outlet 112 in the eighth position (as shown). Figure 2 As shown), open the lower air outlet 12 and the ninth position of the second sub-air outlet 112 (as shown). Figure 1 and Figure 4 (As shown), close the second sub-vent 112 and open the tenth position of the lower vent 12 (as shown). Figure 3 and Figure 5 It rotates back and forth between (as shown). The air conditioner has a first air outlet mode, a second air outlet mode, and a third air outlet mode.

[0038] Based on the air conditioner being in the first air outlet mode (such as...) Figure 2 As shown), the first air valve 14 is in the seventh position and the second air valve 15 is in the eighth position, so that the air valve assembly opens the side air outlet 11 and closes the lower air outlet 12. Based on the air conditioner being in the second air outlet mode (such as...) Figure 3 and Figure 5 As shown), the first air valve 14 is in the sixth position and the second air valve 15 is in the tenth position, so that the air valve assembly closes the side air outlet 11 and opens the lower air outlet 12. Based on the air conditioner being in the third air outlet mode (such as...) Figure 1 and Figure 4 As shown), the first air valve 14 is located at any position between the sixth and seventh positions, and the second air valve 15 is located at the ninth position, so that the air valve assembly opens the side air outlet 11 and the lower air outlet 12.

[0039] Therefore, the air conditioner has three air outlet modes: side air outlet mode (i.e., the first air outlet mode), bottom air outlet mode (i.e., the second air outlet mode), and dual air outlet mode (i.e., the third air outlet mode). When users need rapid cooling or heating, they can select the second air outlet mode, allowing airflow to be discharged downwards through the bottom air outlet 12, facilitating a rapid temperature drop or rise in the lower area. When users want to avoid direct airflow, they can select the first air outlet mode, allowing airflow to be discharged laterally through the side air outlet 11, facilitating long-distance airflow and avoiding direct airflow onto the user. When users want uniform cooling or heating throughout the entire area, they can select the third air outlet mode, allowing airflow to be blown out through both the side air outlet 11 and the bottom air outlet 12, enabling rapid temperature adjustment in the nearby lower area and also providing long-distance airflow for rapid temperature adjustment in distant areas.

[0040] In some exemplary embodiments, the cross-section of the air guide portion of the first air valve 14 may be, but is not limited to, an arc shape, and in the sixth position, the outer surface protrudes forward and the inner surface is recessed forward. The angle between the first air valve 14 and the air outlet 11 can be defined as the angle between the tangent of the outer surface of the air guide portion of the first air valve 14 near the end of the rotation axis of the first air valve 14 and the horizontal plane.

[0041] When the rotation axis of the first air valve 14 is located at the end furthest from the second air valve 15, the air conditioner is in the third air outlet mode (e.g., Figure 1 As shown), the angle θ between the first air valve 14 and the air outlet 11 in the direction of airflow (i.e., the horizontal forward direction) is (as shown). Figure 1 (As shown) The angle can be within the range of 45° to 210°, such as 45°, 60°, 90°, 120°, 150°, 180°, 210°, etc. Testing has shown that this setting provides good airflow.

[0042] With the position where the angle between the first air valve 14 and the air outlet 11 (i.e., the horizontal forward direction) is 90° defined as the 0° position, when the air conditioner is in the third air outlet mode, the first air valve 14 can be located anywhere between the position corresponding to a 45° leftward rotation (denoted as the -45° position) and the position corresponding to a 120° rightward rotation (denoted as the 120° position). When the first air valve 14 is in the -45° position, the angle between it and the air outlet 11 (i.e., the horizontal forward direction) is 45°, and this position can also be, but is not limited to, the sixth position of the first air valve 14. When the first air valve 14 is in the 120° position, the angle between it and the air outlet 11 (i.e., the horizontal forward direction) is 210°, and this position can also be, but is not limited to, the seventh position of the first air valve 14. Therefore, when the air conditioner is in the third air outlet mode, the first air valve 14 can be located at any position between the sixth and seventh positions (it may include the sixth and seventh positions, or it may not include the sixth and seventh positions). The angle between the first air valve 14 and the air outlet direction (i.e., the horizontal forward direction) of the side air outlet 11 can be in the range of 45° to 210°, but is not limited to.

[0043] In some exemplary embodiments, based on the fact that the second air valve 15 is located in the ninth position, the angle δ between the second air valve 15 and the plane where the lower air outlet 12 is located (e.g., Figure 1 (As shown) The angle can be within the range of 30° to 60°, such as 30°, 35°, 40°, 45°, 50°, 55°, 60°, etc. Testing has shown that this setting provides good airflow.

[0044] The cross-section of the air guide portion of the second air valve 15 can be, but is not limited to, an arc shape. The angle between the plane where the second air valve 15 and the lower air outlet 12 are located can be defined as the angle between the tangent of the front end of the surface of the second air valve 15 near the lower air outlet 12 and the horizontal plane.

[0045] In other embodiments (not shown in the figures), the damper assembly includes a rotatable third damper configured to rotate between an eleventh position where the lower air outlet 12 is closed and the side air outlet 11 is open, a twelfth position where both the lower air outlet 12 and the side air outlet 11 are open, and a thirteenth position where the side air outlet 11 is closed and the lower air outlet 12 is open.

[0046] Compared with the aforementioned damper assembly that includes a first damper and a second damper, the damper assembly in this solution only includes a third damper. The opening and closing of the side air outlet 11 and the lower air outlet 12 can be controlled by the third damper, thereby realizing three air outlet modes and simplifying the structure and electrical control program of the air conditioner.

[0047] In the above embodiments, when the damper assembly closes the side air outlet 11, the damper assembly can overlap with the housing 10. This improves the reliability of the damper assembly in closing the side air outlet 11, facilitating the sealing of the side air outlet 11, thereby preventing condensation and whistling. When the damper assembly closes the lower air outlet 12, the damper assembly can overlap with the housing 10. This improves the reliability of the damper assembly in closing the lower air outlet 12, facilitating the sealing of the lower air outlet 12, thereby preventing condensation and whistling.

[0048] In some exemplary embodiments, the first electric damper 21 includes a first drive mechanism (not shown in the figure) and at least one rotatable first air guide plate 211 (e.g., Figures 1 to 5 (As shown). The first drive mechanism is connected to the first air guide plate 211 and is configured to drive the first air guide plate 211 to rotate. In this way, the first drive mechanism drives the first air guide plate 211 to rotate, which realizes the opening and closing of the first ventilation opening 22. The structure is simple, easy to process and form, and also helps to reduce the space required for the first electric damper 21.

[0049] The rotation axis of the first air guide plate 211 extends along the length of the side air outlet 11, which helps to reduce the number of first air guide plates 211 and simplify the structure of the first electric damper 21.

[0050] The first driving mechanism may include a first driving element. The first driving element may be, but is not limited to, a motor. The first driving mechanism may also include a first transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The number of first driving elements and first air guide plates 211 may be equal and correspond one-to-one, or they may not be equal. In other words, the first driving element may drive only one first air guide plate 211 to rotate, or it may drive multiple first air guide plates 211 to rotate (simply by adjusting the first transmission mechanism), or one first air guide plate 211 may be driven by multiple first driving elements.

[0051] In some exemplary embodiments, the second electric damper 31 includes a second drive mechanism (not shown in the figure) and at least one rotatable second air guide plate 311 (e.g., Figures 1 to 5 (As shown). The second drive mechanism is connected to the second air guide plate 311 and is configured to drive the second air guide plate 311 to rotate. In this way, the second drive mechanism drives the second air guide plate 311 to rotate, which realizes the opening and closing of the second ventilation opening 32. The structure is simple, easy to process and form, and also helps to reduce the space required for the second electric damper 31.

[0052] The rotation axis of the second air guide plate 311 extends along the length of the lower air outlet 12, which helps to reduce the number of second air guide plates 311 and simplify the structure of the second electric damper 31.

[0053] The second drive mechanism may include a second drive component. The second drive component may be, but is not limited to, a motor. The second drive mechanism may also include a second transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The number of second drive components and second air guide plates 311 may be equal and correspond one-to-one, or they may be unequal. In other words, the second drive component may drive only one second air guide plate 311 to rotate, or it may drive multiple second air guide plates 311 to rotate (simply by adjusting the second transmission mechanism), or one second air guide plate 311 may be driven by multiple second drive components.

[0054] In some exemplary embodiments, such as Figures 1 to 5 As shown, the width of the first ventilation opening 22 is greater than or equal to the width of the second ventilation opening 32, and there are multiple first air guide plates 211 arranged side by side along the width direction (i.e., the vertical direction) of the first ventilation opening 22.

[0055] This reduces the width of a single first air guide plate 211, which helps reduce the space required for rotation of the first air guide plate 211, thereby reducing the distance between the first electric panel 2 and the embedded air conditioner indoor unit 1, and further reducing the depth of the ceiling 5.

[0056] The number of second air guide plates 311 can also be multiple, with multiple second air guide plates 311 arranged side by side along the width direction of the second ventilation opening 32.

[0057] Of course, the width of the first vent 22 can also be less than or equal to the width of the second vent 32.

[0058] In some exemplary embodiments, the first air guide plate 211 is configured to rotate and switch between a closed state and an open state. The second air guide plate 311 is configured to rotate and switch between a closed state and an open state. The air conditioner has a first air outlet mode, a second air outlet mode, and a third air outlet mode.

[0059] Based on the air conditioner being in the first air outlet mode (such as...) Figure 2 As shown), the first air guide plate 211 is in the open state and the second air guide plate 311 is in the closed state, so that the first electric damper 21 opens the first ventilation opening 22 and the second electric damper 31 closes the second ventilation opening 32.

[0060] Based on the air conditioner being in the second air outlet mode (such as...) Figure 3 and Figure 5 As shown), the first air guide plate 211 is in the closed state and the second air guide plate 311 is in the open state, so that the first electric damper 21 closes the first vent 22 and the second electric damper 31 opens the second vent 32.

[0061] Based on the air conditioner being in the third air outlet mode (such as...) Figure 1 and Figure 4 As shown), the first air guide plate 211 is in the open state and the second air guide plate 311 is in the open state, so that the first electric damper 21 opens the first ventilation port 22 and the second electric damper 31 opens the second ventilation port 32.

[0062] Therefore, the air conditioner has three air outlet modes: side air outlet mode (i.e., the first air outlet mode), bottom air outlet mode (i.e., the second air outlet mode), and dual air outlet mode (i.e., the third air outlet mode). When the user needs rapid cooling or heating, they can select the second air outlet mode, in which the airflow is discharged downwards through the bottom air outlet 12 and the second vent 32, facilitating a rapid temperature drop or rise in the lower area. When the user wants to avoid direct airflow, they can select the first air outlet mode, in which the airflow is discharged laterally through the side air outlet 11 and the first vent 22, facilitating long-distance airflow and avoiding direct airflow to the user. When the user wants uniform cooling or heating throughout the entire area, they can select the third air outlet mode, in which the airflow is blown out together through the side air outlet 11 and the bottom air outlet 12, which can quickly adjust the temperature of the nearby lower area and also deliver air over a long distance, enabling rapid temperature adjustment in distant areas as well.

[0063] Understandably, the first air guide plate 211, when open, has different opening angles, corresponding to different positions. Therefore, the first air guide plate 211 can have multiple opening positions when open, and its opening position can differ depending on the airflow mode. Furthermore, the first air guide plate 211 can have an up-and-down swing function, that is, it can rotate back and forth between different opening positions to avoid continuously supplying air in the same direction, which helps improve the uniformity of indoor temperature. The swing range of the first air guide plate 211 can be, but is not limited to, 0° (corresponding to the closed state) to 90°, thereby achieving airflow from 0° to 90° at both near and far distances.

[0064] Similarly, the second air guide plate 311, when open, has different opening angles and corresponding positions. Therefore, the second air guide plate 311 can have multiple opening positions when open, and its opening position can differ under different airflow modes. Furthermore, the second air guide plate 311 can have a back-and-forth swing function, that is, it can rotate back and forth between different opening positions to avoid continuously supplying air in the same direction, which helps improve the uniformity of indoor temperature. The swing range of the second air guide plate 311 can be, but is not limited to, 0° (corresponding to the closed state) to 90°, thereby achieving airflow from 0° to 90° at both near and far distances.

[0065] In some exemplary embodiments, based on the first air guide plate 211 being in the closed state, the first air guide plate 211 is located in a first position, such as... Figure 3 and Figure 5 As shown. With the first air guide plate 211 in the open state and the air conditioner in the third air outlet mode, the first air guide plate 211 is in the second position, as... Figure 1 and Figure 4 As shown. With the first air guide plate 211 in the open state and the air conditioner in the first air outlet mode, the first air guide plate 211 is located in the third position as shown. Figure 2 As shown. The rotation amplitude of the first air guide plate 211 from the first position to the second position is less than the rotation amplitude of the first air guide plate 211 from the first position to the third position.

[0066] Therefore, the opening angle of the first air guide plate 211 in side air outlet mode is greater than that in dual air outlet mode, which helps to increase the air delivery distance in side air outlet mode. Of course, the opening angle of the first air guide plate 211 in side air outlet mode can also be equal to or less than that in dual air outlet mode.

[0067] In some exemplary embodiments, based on the second air guide plate 311 being in the closed state, the second air guide plate 311 is located in the fourth position, such as... Figure 2 As shown. With the second air guide plate 311 in the open state and the air conditioner in the second air outlet mode, the second air guide plate 311 is located in the fifth position, as... Figure 3As shown. With the second air guide plate 311 in the open state and the air conditioner in the third air outlet mode, the second air guide plate 311 is located in the fifth position, as... Figure 1 and Figure 4 As shown.

[0068] Therefore, the opening angle of the second air guide plate 311 in side air outlet mode is equal to the opening angle in dual air outlet mode, which simplifies the electronic control program of the second air guide plate 311. Of course, the opening angle of the second air guide plate 311 in side air outlet mode can also be less than or greater than the opening angle in dual air outlet mode.

[0069] In some exemplary embodiments, based on the first air guide plate 211 being located in the second position, the included angle α between the first air guide plate 211 and the plane containing the first vent 22 (e.g., Figure 1 (As shown) The angle can be within the range of 45° to 60°, such as 45°, 50°, 55°, 60°, etc. Experiments have verified that this allows the dual-outlet mode to achieve better performance.

[0070] Based on the fact that the first air guide plate 211 is located in the third position, the included angle γ between the first air guide plate 211 and the plane where the first vent 22 is located (e.g., Figure 2 (As shown) The angle can be within the range of 60° to 90°, such as 60°, 70°, 80°, 90°, etc. Experiments have verified that this allows the side-discharge mode to achieve better performance.

[0071] Based on the fact that the second air guide plate 311 is located in the fifth position, the included angle β between the plane where the second air guide plate 311 and the second vent 32 are located (e.g., Figure 1 (As shown) The angle can be within the range of 25° to 60°, such as 25°, 30°, 40°, 45°, 50°, 60°, etc. Experiments have verified that this allows the dual-outlet and bottom-outlet modes to achieve better performance.

[0072] In some exemplary embodiments, the first electric panel 2 is further provided with a first air-sweeping assembly (not shown in the figure), which includes a plurality of first sway blades, the swaying axis of the first sway blades extending along the width of the first vent 22.

[0073] The first air-sweeping assembly may further include a first connecting rod and a third drive mechanism. The third drive mechanism may include a third drive element, which may be, but is not limited to, a motor. The third drive mechanism may also include a third transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, a crank-connecting rod transmission mechanism, etc. The first connecting rod is connected to the third drive mechanism, and multiple first swing blades are rotatably connected to the first connecting rod. The first connecting rod extends along the length of the first vent 22, and the swing axis of the first swing blades extends along the width of the first vent 22, thereby realizing left and right air-sweeping functions. This further expands the air supply range of the air conditioner's side air outlet function, which is beneficial for improving the uniformity of indoor temperature and enhancing the user experience. The specific structure of the first air-sweeping assembly can be referenced from the air-sweeping assembly of a conventional air conditioner, and will not be elaborated further here.

[0074] In some exemplary embodiments, the second electric panel 3 is further provided with a second air-sweeping assembly (not shown in the figure), which includes a plurality of second swing blades, the swing axis of which extends along the width direction of the second vent 32.

[0075] The second swing assembly may further include a second connecting rod and a fourth drive mechanism. The fourth drive mechanism may include a fourth drive element, which may be, but is not limited to, a motor. The fourth drive mechanism may also include a fourth transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, a crank-connecting rod transmission mechanism, etc. The second connecting rod is connected to the fourth drive mechanism, and multiple second swing blades are rotatably connected to the second connecting rod. The second connecting rod extends along the length of the second vent 32, and the swing axis of the second swing blades extends along the width of the second vent 32, thereby realizing the left and right swing function. This further expands the air supply range of the air conditioner's lower air outlet function, which is beneficial for improving the uniformity of indoor temperature and enhancing the user experience. The specific structure of the second swing assembly can be referenced from the swing assembly of a conventional air conditioner, and will not be elaborated further here.

[0076] In some exemplary embodiments, a first sweeping assembly is further provided based on the first electric panel 2. The sweeping angle range of the first sweeping assembly can be, but is not limited to, -60° to 60°. In other words, the first sweeping assembly reciprocates between a -60° position and a 60° position.

[0077] The 0° position of the first air-sweeping assembly corresponds to the position when the first swing blade is perpendicular to the plane of the first vent 22. Based on this, the first swing blade can rotate 60° in one direction to reach the -60° position, and rotate 60° in the other direction to reach the 60° position.

[0078] The second electric panel 3 is further provided with a second air-sweeping assembly, the air-sweeping angle of which can be within, but is not limited to, -60° to 60°. In other words, the second air-sweeping assembly reciprocates between a -60° position and a 60° position.

[0079] The 0° position of the second air-sweeping assembly corresponds to the position when the second swing blade is perpendicular to the plane of the second vent 32. Based on this, the second swing blade can rotate 60° in one direction to reach the -60° position, and rotate 60° in the other direction to reach the 60° position.

[0080] In some exemplary embodiments, such as Figure 1 As shown, the first electric control panel 2 is spaced apart from the embedded air conditioner indoor unit 1 and is flexibly connected by the air outlet canvas 41. This design facilitates the reasonable setting of the respective positions and dimensions of the embedded air conditioner indoor unit 1 and the first electric control panel 2 as needed, which is beneficial to improving the versatility of the embedded air conditioner indoor unit 1 and the first electric control panel 2.

[0081] Alternatively, the first electric panel 2 can be rigidly connected to the embedded air conditioner indoor unit 1 using fasteners 42 (such as screws, bolts, etc.). This solution improves the reliability and compatibility of the connection between the first electric panel 2 and the embedded air conditioner indoor unit 1.

[0082] In some exemplary embodiments, such as Figures 1 to 3 As shown, the second electric control panel 3 is spaced apart from the recessed air conditioner indoor unit 1 and is flexibly connected by the air outlet canvas 41. This design facilitates the reasonable setting of the respective positions and dimensions of the recessed air conditioner indoor unit 1 and the second electric control panel 3 as needed, which is beneficial to improving the versatility of the recessed air conditioner indoor unit 1 and the second electric control panel 3.

[0083] Alternatively, the second electric panel 3 can be rigidly connected to the recessed air conditioner indoor unit 1 via fasteners 42 (such as screws, bolts, etc.). Figure 4 and Figure 5 As shown. This solution helps improve the reliability and compatibility of the connection between the second electric panel 3 and the embedded air conditioner indoor unit 1.

[0084] The suspended ceiling 5 includes side panels and a bottom panel, both of which are connected to the wall 6. A first electric control panel 2 is embedded in the side panel of the suspended ceiling 5, and a second electric control panel 3 is embedded in the bottom panel of the suspended ceiling 5. Since the suspended ceiling 5 is relatively thin, while the first and second electric control panels 2 and 3 have multiple functional structures and are relatively thick, a limiting block 51 (such as...) can be installed on the inner side of the suspended ceiling 5. Figure 1As shown), the portion of the first electric panel 2 / second electric panel 3 extending into the ceiling 5 is stopped and limited. The limiting block 51 can be, but is not limited to, a wooden limiting block. Furthermore, for the second electric panel 3, when it is flexibly connected to the recessed air conditioner indoor unit 1 via canvas 41, the second electric panel 3 can be fixedly connected to the base plate of the ceiling 5 and the limiting block 51 using fasteners 42 or other methods (such as...). Figure 1 (Vegetarian) to ensure the reliability of the second electric panel 3. The first electric panel 2 can be kept stable by the support of the ceiling 5 and can be fixed to the side panel of the ceiling 5 without the need for fasteners 42.

[0085] In some exemplary embodiments, the bottom of the housing 10 is provided with a return air vent 13, such as... Figure 1 As shown, the return air vent 13 and the lower air outlet 12 are spaced apart. The air conditioner also includes a return air panel, which is further provided with a third vent 33 that is connected to the return air vent.

[0086] In some embodiments, the second electric panel 3 includes a second panel body, a second vent 32 is disposed on the second panel body, and a return air panel is integrally formed with the second panel body.

[0087] Alternatively, the second electric panel 3 is also provided with a third ventilation opening 33 that corresponds to and communicates with the return air opening 13, such as Figure 4 and Figure 5 As shown, the third vent 33 is spaced apart from the second vent 32. In other words, the second electric panel 3 can integrate both downward air outlet and return air functions.

[0088] The second electric control panel 3 may also be provided with a third electric damper for controlling the opening and closing of the third vent 33. Alternatively, the second electric control panel 3 may be provided with a return air grille located at the third vent 33.

[0089] Of course, the second motorized panel 3 may also lack the return air function. The return air vent 13 can be used with the engineering panel 7.

[0090] In some exemplary embodiments, the damper assembly further includes a damper drive mechanism. The damper drive mechanism may include a damper drive element, which may be, but is not limited to, a damper motor. The damper drive mechanism may also include a damper transmission mechanism, which may be, but is not limited to, a gear transmission mechanism, a rack and pinion transmission mechanism, etc. The number of damper drive elements may be equal to and correspond one-to-one with the number of dampers, or they may be unequal.

[0091] In some exemplary embodiments, such as Figure 6As shown, the first air guide plate 211 is provided with multiple windless sensing holes 2111. In this way, when the first air guide plate 211 closes the first ventilation opening 22, the airflow can be discharged through the windless sensing holes 2111 of the first air guide plate 211, achieving a windless effect, which helps to improve the user experience.

[0092] The second air guide plate 311 is provided with multiple windless sensing holes 2111. In this way, when the second air guide plate 311 closes the second vent 32, the airflow can be discharged through the windless sensing holes 2111 of the second air guide plate 311, achieving a windless effect, which helps to improve the user experience.

[0093] In some exemplary embodiments, the air conditioner includes a controller that is electrically connected to a first electric panel 2, a second electric panel 3, and an air valve assembly, and is configured to control the operation of a first electric damper 21, a second electric damper 31, and the air valve assembly, so that the air conditioner can switch between a first air outlet mode, a second air outlet mode, and a third air outlet mode.

[0094] In some exemplary embodiments, the air conditioner may operate according to the following logic: When cooling mode is activated, the air conditioner automatically recognizes parameters and defaults to rapid cooling mode. At this time, the side air outlet 11 and the first vent 22 are closed, while the lower air outlet 12 and the second vent 32 are open. Pressing the air outlet button allows cold air to quickly reach the ground. The first air valve 14 is in position six, the second air valve 15 is in position ten, the second air guide plate 311 of the second electric panel 3 is open in position five, and the first air guide plate 211 of the first electric panel 2 is closed in position one. After running continuously for t1 minutes, the lower air outlet 12 and the second vent 32 close, the side air outlet 11 and the first vent 22 open, the first air valve 14 is in position seven, the second air valve 15 is in position eight, and the first air guide plate 211 of the first electric panel 2 is open in position three. The system continues to operate in side air outlet mode to prevent cold air from blowing directly on people. It can also control the air guide angle (the first air guide plate 211 / the second air guide plate 311 can achieve 0~90 degrees of far and near air sweeping) and the air sweeping angle (the first air sweeping component / the second air sweeping component can sweep left and right at -60~60 degrees) under different air outlet conditions to achieve multi-directional (far, near, left, right) air sweeping, so as to meet the cooling needs of different groups of people.

[0095] When the air conditioner is in cooling mode, it automatically identifies the parameters. If it detects that the user has selected the normal cooling mode, it will operate in the side air outlet mode. At this time, the first air valve 14 is in the seventh position, the second air valve 15 is in the eighth position, the second air guide plate 311 of the second electric panel 3 is closed and in the fourth position, and the first air guide plate 211 of the first electric panel 2 is open and in the third position.

[0096] When the air conditioner is in cooling mode, it automatically identifies the parameters and recognizes that the user has selected the full-area cooling mode. It then operates in dual-airflow mode. At this time, the first air valve 14 is located at any position between the sixth and seventh positions, and the second air valve 15 is located at the ninth position. Both the first air guide plate 211 and the second air guide plate 311 are open (the air guide plates can achieve 0~90 degrees of near and far airflow, and -60~60 degrees of left and right airflow). By controlling the two electric panels, multi-directional (far, near, left, right) airflow can be performed according to the user's needs to meet the cooling needs of different groups of people and achieve full-area airflow throughout the house.

[0097] When in heating mode, the air conditioner automatically recognizes parameters and defaults to rapid heating mode. At this time, the side air outlet 11 and the first vent 22 are closed, while the lower air outlet 12 and the second vent 32 are open. Pressing the air outlet button activates the mode. The first air valve 14 is in position six, the second air valve 15 is in position ten, the second air guide plate 311 of the second electric panel 3 is open in position five, and the first air guide plate 211 of the first electric panel 2 is closed in position one. The second air guide plate 311 can achieve 0-90 degree near and far air swing, and the second air swing component can achieve -60 to 60 degree left and right air swing. After continuous operation for t2 minutes, the lower air outlet 12 and the second vent 32 remain open, while the side air outlet 11 and the first vent 22 remain open, continuing operation in dual-air outlet mode (the two electric panels can perform multi-directional (far, near, left, right) air swing according to user needs to meet the heating needs of different groups). Alternatively, the user can choose to close the lower air outlet and only open the side air outlet.

[0098] When heating is running, the air conditioner automatically identifies the parameters and recognizes that the user has selected the normal heating mode. It then operates in the side air outlet mode. At this time, the first air valve 14 is in the seventh position, the second air valve 15 is in the eighth position, the second air guide plate 311 of the second electric panel 3 is closed and in the fourth position, and the first air guide plate 211 of the first electric panel 2 is open and in the third position.

[0099] When heating is in operation, the air conditioner automatically identifies parameters and recognizes that the user has selected the full-area heating mode. It then operates in dual-airflow mode. At this time, the first air valve 14 is in any position between the sixth and seventh positions, the second air valve 15 is in the ninth position, the second air guide plate 311 of the second electric panel 3 is open and in the fifth position, and the first air guide plate 211 of the first electric panel 2 is open and in the second position. The air guide angle (the first air guide plate 211 / second air guide plate 311 can achieve 0~90 degrees of near and far sweeping) and sweeping angle (the first sweeping assembly / second sweeping assembly can sweep left and right at -60~60 degrees) of both electric panels can be controlled to perform multi-directional (far, near, left, right) sweeping, meeting the heating needs of different groups of people.

[0100] This air conditioner allows the ducted indoor unit, when paired with an electric control panel, to effectively deliver hot air to the ground and can provide multi-directional, all-area airflow according to user needs; it also features fast cooling / heating speed, a compact structure, and a wide cooling / heating airflow coverage area, which can be freely selected according to user needs.

[0101] In some other exemplary embodiments, both the first air guide plate 211 and the second air guide plate 311 are provided with windless through holes 2111. The air conditioner can operate according to the following logic: When cooling is in operation, the air conditioner automatically recognizes parameters and defaults to rapid cooling mode. At this time, the side air outlet 11 and the first vent 22 are closed, while the lower air outlet 12 and the second vent 32 are open. Pressing the air outlet button activates the airflow mode, and cold air quickly reaches the ground. At this time, the first air valve 14 is in position six, the second air valve 15 is in position ten, the second air guide plate 311 of the second electric panel 3 is open in position five, and the first air guide plate 211 of the first electric panel 2 is closed in position one. After running continuously for t1 minutes, the first vent 22 and the second vent 32 close, the side air outlet 11 and the lower air outlet 12 open, the first air valve 14 is in position seven, the second air valve 15 is in position nine, the first air guide plate 211 is closed in position one, and the second air guide plate 311 is in position four. The system continues to operate in windless mode to prevent cold air from blowing on people.

[0102] When the air conditioner is in cooling mode, it automatically identifies parameters and recognizes that the user has selected the normal cooling mode. It then operates in side-outlet mode, with the first air valve 14 in position seven, the second air valve 15 in position eight, the second air guide plate 311 of the second electric panel 3 closed (position four), and the first air guide plate 211 of the first electric panel 2 open (position three). After running continuously for t2 minutes, the first and second vents 22 close, the side air outlet 11 and the lower air outlet 12 open, the first air valve 14 is in position seven, the second air valve 15 is in position nine, the first air guide plate 211 is closed (position one), and the second air guide plate 311 is in position four, continuing to operate in a draft-free mode to prevent cold air from blowing directly on people.

[0103] When cooling mode is activated, the air conditioner automatically identifies parameters and recognizes that the user has selected the full-area cooling mode. It then operates in dual-airflow mode, with the first air valve 14 in position seven, the second air valve 15 in position nine, and both the first air guide plate 211 and the second air guide plate 311 open. After running continuously for t3 minutes, the first and second air vents 22 and 32 close, the side air outlet 11 and the lower air outlet 12 open, the first air valve 14 remains in position seven, the second air valve 15 remains in position nine, the first air guide plate 211 closes to position one, and the second air guide plate 311 remains in position four. The system continues to operate in a draft-free mode to prevent cold air from blowing directly on people.

[0104] Since the windless mode is generally not required in heating mode, the operating logic of the air conditioner in heating mode can be the same as that of an air conditioner without a windless mode, that is: When in heating mode, the air conditioner automatically recognizes parameters and defaults to rapid heating mode. At this time, the side air outlet 11 and the first vent 22 are closed, while the lower air outlet 12 and the second vent 32 are open. Pressing the air outlet button activates the mode. The first air valve 14 is in position six, the second air valve 15 is in position ten, the second air guide plate 311 of the second electric panel 3 is open in position five, and the first air guide plate 211 of the first electric panel 2 is closed in position one. The second air guide plate 311 can achieve 0-90 degree near and far air swing, and the second air swing component can achieve -60 to 60 degree left and right air swing. After continuous operation for t2 minutes, the lower air outlet 12 and the second vent 32 remain open, while the side air outlet 11 and the first vent 22 remain open, continuing operation in dual-air outlet mode (the two electric panels can perform multi-directional (far, near, left, right) air swing according to user needs to meet the heating needs of different groups). Alternatively, the user can choose to close the lower air outlet and only open the side air outlet.

[0105] When heating is running, the air conditioner automatically identifies the parameters and recognizes that the user has selected the normal heating mode. It then operates in the side air outlet mode. At this time, the first air valve 14 is in the seventh position, the second air valve 15 is in the eighth position, the second air guide plate 311 of the second electric panel 3 is closed and in the fourth position, and the first air guide plate 211 of the first electric panel 2 is open and in the third position.

[0106] When heating is in operation, the air conditioner automatically identifies parameters and recognizes that the user has selected the full-area heating mode. It then operates in dual-airflow mode. At this time, the first air valve 14 is in any position between the sixth and seventh positions, the second air valve 15 is in the ninth position, the second air guide plate 311 of the second electric panel 3 is open and in the fifth position, and the first air guide plate 211 of the first electric panel 2 is open and in the second position. The air guide angle (the first air guide plate 211 / second air guide plate 311 can achieve 0~90 degrees of near and far sweeping) and sweeping angle (the first sweeping assembly / second sweeping assembly can sweep left and right at -60~60 degrees) of both electric panels can be controlled to perform multi-directional (far, near, left, right) sweeping, meeting the heating needs of different groups of people.

[0107] This air conditioner allows the ducted indoor unit, when paired with an electric control panel, to effectively deliver hot air to the ground and can provide multi-directional, all-area airflow according to user needs; it also features fast cooling / heating speed, a compact structure, and a wide cooling / heating airflow coverage area, which can be freely selected according to user needs.
