Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and more specifically, to a wall-mounted air conditioner. Background Technology

[0002] Currently, most household wall-mounted air conditioners have a single air outlet, using the oscillation of an air deflector to change the direction of airflow. However, this design suffers from technical problems such as a limited airflow method, poor comfort, and low airflow organization efficiency.

[0003] While some dual-outlet designs have emerged in existing technologies, most employ dual cross-flow fans or complex duct systems, lacking the ability to dynamically balance airflow between the upper and lower outlets in real time. In practical applications, the pressure gradient differences between the upper and lower outlet ducts make it difficult to achieve a reasonable distribution of airflow under different air supply modes and to maintain a stable airflow ratio, thus affecting the stability of the air supply effect. Therefore, how to achieve controllable airflow ratios while maintaining air supply comfort under various air supply modes has become an urgent technical problem to be solved. Utility Model Content

[0006] In this embodiment, a first air duct section and a second air duct section are provided. The first air duct section connects the air inlet and the lower air outlet, and the second air duct section connects the first air duct section and the upper air outlet. By controlling the movement position of the damper, multiple air outlet modes can be achieved. The damper works in coordination with the first air guide and the second air guide to ensure the air volume when only the upper or lower air outlet is exposed.

[0036] Because existing air conditioners with dual air outlet designs typically employ dual cross-flow fan blades or complex duct structures, in practical applications, the difference in pressure gradient between the upper and lower air outlet ducts makes it difficult to achieve a reasonable distribution of airflow under different air supply modes. Specifically, when the widths of the upper and lower air outlet ducts are similar, the airflow in the upper air outlet duct is much greater than that in the lower air outlet duct; while if the width of the upper air outlet duct is significantly smaller than that of the lower air outlet duct, although the airflow ratio between the upper and lower air outlets can be balanced, the wind resistance is too high when only the upper air outlet is used, resulting in insufficient airflow; if the width of the upper air outlet duct is too large, there is almost no airflow output in the lower air outlet duct. In addition, the flow field distribution of the cross-flow fan changes at different speeds, making it difficult to maintain a stable airflow ratio using a fixed split structure, thus affecting the stability of the air supply effect.

[0037] Therefore, in order to solve the technical problem of how an air conditioner with dual air outlets can achieve controllable airflow ratios and maintain airflow comfort in various air supply modes, this embodiment proposes a wall-mounted air conditioner, which includes: The indoor unit housing has an air inlet, an upper air outlet, and a lower air outlet. The air inlet is located at the top of the indoor unit housing, the upper air outlet is located at the front of the indoor unit housing, and the lower air outlet is located at the bottom of the indoor unit housing. The air duct is located inside the indoor unit housing. The air duct includes a first air duct section and a second air duct section. The first air duct section connects the air inlet and the lower air outlet, and the second air duct section connects the first air duct section and the upper air outlet. An air damper is movably disposed between the first air duct section and the second air duct section. The air damper has multiple movable positions and can be controlled in different movable positions to realize multiple air outlet modes of the air conditioner. The upper air guide assembly includes a first air guide component and a second air guide component. The first air guide component is rotatably disposed at the upper end of the upper air outlet, and the second air guide component is rotatably disposed at the lower end of the upper air outlet. The first air guide component and the second air guide component cooperate to open or close the upper air outlet.

[0038] This embodiment sets up a first air duct section and a second air duct section. The first air duct section connects the air inlet and the lower air outlet, and the second air duct section connects the first air duct section and the upper air outlet. By controlling the movement position of the damper, multiple air outlet modes can be realized. The damper works in coordination with the first air guide and the second air guide to ensure the air volume when only the upper or lower air outlet is exposed. When the upper and lower air outlets are exposed at the same time, the air volume of the upper air outlet and the lower air outlet is reasonably distributed to ensure the comfort of air supply.

[0039] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following implementation methods and examples can be combined with each other.

[0040] This embodiment proposes a wall-mounted air conditioner, such as... Figures 1-8 As shown, the air conditioner includes an indoor unit casing 1, an air duct, and an air damper 4. Wherein: The indoor unit housing 1 has an air inlet, an upper air outlet 11, and a lower air outlet 12. The air inlet is located at the top of the indoor unit housing 1, the upper air outlet 11 is located at the front of the indoor unit housing 1, and the lower air outlet 12 is located at the bottom of the indoor unit housing 1. (Refer to...) Figures 1-8 The air inlet is located on the top cover of the indoor unit housing 1, and the upper air outlet is located on the front panel of the indoor unit housing 1, above the indoor unit housing 1. Preferably, the upper air outlet is located near the air inlet. The lower air outlet is located on the bottom plate of the indoor unit housing 1.

[0041] The air duct is located inside the indoor unit housing 1, and the air duct includes a first air duct section 2 and a second air duct section 3.

[0042] The first air duct section 2 connects the air inlet and the lower air outlet 12, and includes an upper opening and a lower opening. The upper opening is located inside the indoor unit housing 1 and faces the air inlet, while the lower opening corresponds to the lower air outlet 12. The first air duct section 2 extends from the upper opening to the lower opening. Preferably, both the rear and front air duct walls of the first air duct section 2 have a rear-to-front extension trend, so that the airflow from the lower air outlet has an airflow tendency toward the front of the indoor unit housing 1.

[0043] The air inlet 31 of the second air duct section 3 is connected to the first air duct section 2, and the air outlet is connected to the upper air outlet 11. In one example, the air inlet 31 of the second air duct section 3 is connected to the lower opening of the first air duct section 2, and the second air duct section 3 extends from bottom to top along the front panel of the indoor unit housing 1 to the upper air outlet 11. In other possible implementations, the air inlet 31 of the second air duct section 3 may not be connected to the lower opening of the first air duct section 2, but may be connected to a connecting opening formed on the front air duct wall of the first air duct section 2.

[0044] The damper 4 is movably disposed between the first air duct section 2 and the second air duct section 3. The movable positions of the damper 4 include a first position, a second position, and a third position. In the first position, the damper 4 at least closes the passage between the first air duct section 2 and the second air duct section 3. In the second position, the damper 4 at least opens the passage between the first air duct section 2 and the second air duct section 3. In the third position, the damper 4 at least opens the passage between the first air duct section 2 and the second air duct section 3, and when the damper 4 is in the third position, the air intake volume of the second air duct section 3 is not greater than the air intake volume of the damper 4 in the second position. The damper 4 can be controlled to different movable positions to achieve multiple air outlet modes of the air conditioner.

[0045] In one example, the air outlet methods of the air conditioner include single top air outlet, single bottom air outlet, and simultaneous top and bottom air outlet; like Figure 4 and Figure 5 As shown, when the air is vented from the bottom, the damper 4 is controlled to be in the first position of closing the air inlet end 31 of the second air duct section 3, and the lower air outlet 12 is in the open state. The airflow from the first air duct section 2 cannot enter the second air duct section 3 and exit from the upper air outlet 11, but instead exits entirely from the lower air outlet 12.

[0046] like Figure 2 and Figure 3 As shown, when the air is vented from the top, the damper 4 is controlled to the second position where the air inlet end 31 of the second air duct section 3 is opened, and the lower air outlet 12 is closed. The airflow from the first air duct section 2 cannot be vented from the lower air outlet 12, but instead enters the second air duct section 3 and is vented from the upper air outlet 11.

[0047] like Figures 6-8 As shown, when air is vented from both the top and bottom, the damper 4 is controlled to be in the third position of opening the air inlet end 31 of the second air duct section 3, and the lower air outlet 12 is in the open state. Part of the airflow from the first air duct section 2 can be vented from the lower air outlet 12, and another part of the airflow can enter the second air duct section 3 and be vented from the upper air outlet 11.

[0048] This embodiment allows for the switching of different air outlet modes based on air outlet mode, indoor temperature, and other factors by adjusting the position of the four components of the damper, thereby improving indoor comfort.

[0049] In one alternative implementation, such as Figures 2-8 As shown, the damper 4 is pivotally mounted at the lower end of the air inlet 31 of the second air duct section 3. In a specific example, the damper 4 has a plate-like structure, with its lower end hinged to the lower end of the air inlet 31. The opening angle of the damper 4 in the second position is greater than that in the third position. For example, the damper fully opens the air outlet of the second air duct section 3 in the second position and partially opens the air outlet of the second air duct section 3 in the third position.

[0050] In a preferred embodiment, such as Figure 4 and Figure 5 As shown, in the first position, the damper 4 closes the passage between the first air duct section 2 and the second air duct section 3, and opens the passage between the first air duct section 2 and the lower air outlet 12; as Figure 2 and Figure 3 As shown, in the second position, the damper 4 opens the passage between the first air duct section 2 and the second air duct section 3, and closes the passage between the first air duct section 2 and the lower air outlet 12; as Figures 6-8 As shown, in the third position, the damper 4 opens the passage between the first air duct section 2 and the second air duct section 3, and also opens the passage between the first air duct section 2 and the lower air outlet 12.

[0051] This embodiment can control the on / off state of the passage between the second air duct section 3 and the first air duct section 2, as well as the on / off state of the passage between the lower air outlet 12 and the first air duct section 2, through the damper 4, simplifying the structure and reducing production costs.

[0052] In one alternative implementation, such as Figure 5 As shown, the air conditioner includes a lower air guide 7, which is movably disposed at the lower air outlet 12. The lower air guide 7 can adjust the air outlet direction of the lower air outlet 12 when there is only lower air outlet or when there is air outlet at both the upper and lower sides. In this embodiment, the lower air guide 7 and the damper 4 can work together to adjust the air volume and air direction, further improving the indoor temperature regulation effect.

[0053] In a preferred embodiment, the air inlet 31 of the second air duct section 3 is located near the lower air outlet 12 and is connected to the lower air outlet 12. The first air guide 61 is a plate-shaped structure similar to the air damper 4. When the air damper 4 is in the second position, the lower air guide 7 moves to a position that fits against the lower end surface of the air damper 4, so as to achieve the appearance consistency of the bottom of the indoor unit housing 1 in the single lower air outlet state and improve the overall aesthetics.

[0054] The configuration of the damper 4 in this embodiment is not limited to the form proposed above. In other possible implementations (not shown in the figures of this embodiment), the damper 4 includes a damper 4 body and a movable baffle. The damper 4 body is disposed at the air outlet end of the second air duct section 3, and the shape of the damper 4 body is adapted to the shape of the air outlet end of the second air duct. The damper 4 body has a through hole, and the movable baffle is rotatably disposed on the damper 4 body and can rotate in the circumferential direction of the damper 4 body to open or close the through hole, thereby opening or closing the air inlet end 31 of the second air duct section 3. The movable baffle can also adjust the opening degree of the through hole, thereby adjusting the air intake volume of the second air duct section 3. In this embodiment, the lower air guide 7 disposed at the lower air outlet 12 can be used to open or close the lower air outlet 12. Through the coordinated cooperation between the lower air outlet 12 and the damper 4, the air conditioner can achieve single upper air outlet, single lower air outlet, or simultaneous upper and lower air outlet.

[0055] In one alternative implementation, such as Figures 1-8As shown, the air conditioner also includes a sweeping blade 5, which is movably disposed in the first air duct section 2 and opposite to the air outlet end of the second air duct section 3. The sweeping blade 5 has an extended state and a retracted state. When the sweeping blade 5 is in the extended state, it can guide the airflow direction within the first air duct section 2. When the sweeping blade 5 is in the retracted state, it cannot guide the airflow direction within the first air duct section 2. In a specific example, the sweeping blade 5 is foldable and disposed within the second air duct section 3. When the sweeping blade 5 is in the extended state, it changes from a folded state to an upright state. When the sweeping blade 5 is in the retracted state, it changes from an upright state to a folded state. It should be noted that the upright state referred to in this embodiment does not mean that the sweeping blade 5 is in a vertically upward state, but rather that the air duct wall on which the sweeping blade 5 is disposed is in an upright state.

[0056] In single top-outlet or single bottom-outlet configurations, the sweeping blades 5 are controlled to be extended to guide the airflow direction, for example, as... Figure 2 and Figure 3 As shown, in single-airflow operation, the sweeping blades 5 are controlled to guide the airflow within the first air duct section 2 to the second air duct section 3; as Figure 4 and Figure 5 As shown, during single-downward airflow, the sweeping blades 5 are controlled to guide the airflow in the first air duct section 2 to the downward air outlet 12, thereby accelerating the airflow efficiency.

[0057] like Figures 6-8 As shown, when air is discharged from both the top and bottom simultaneously, the sweeping blade 5 is controlled to be in the retracted state. Since the airflow in the second air duct needs to flow into the lower air duct and the second air duct section 3 at the same time, there is no need for the sweeping component to guide it. At this time, controlling the sweeping blade 5 to be in the retracted state can reduce the airflow resistance when the airflow flows from the first air duct section 2 to the lower air outlet 12 and the second air duct.

[0058] In one alternative implementation, such as Figures 1-8 As shown, the air conditioner also includes an upper air guide assembly 6, which is movably disposed at the upper air outlet 11. The upper air guide assembly 6 includes a first air guide 61 and a second air guide 62. The first air guide 61 is rotatably disposed at the upper end of the upper air outlet 11, and the second air guide 62 is rotatably disposed at the lower end of the upper air outlet 11. The first air guide 61 and the second air guide 62 cooperate to open or close the upper air outlet 11.

[0059] In a specific example, both the first air guide 61 and the second air guide 62 are plate-shaped structures. The first air guide 61 includes a first air guide plate, and the second air guide 62 includes a second air guide plate. The upper end of the first air guide 61 is pivotally connected to the upper end of the upper air outlet 11, and the lower end of the second air guide 62 is pivotally connected to the lower end of the upper air outlet 11. When the first air guide 61 is snapped downwards onto the upper air outlet 11, and the second air guide 62 is snapped upwards onto the upper air outlet 11, the first air guide 61 and the second air guide 62 cooperate to seal the upper air outlet 11. Simultaneously, the first air guide 61 opens upwards from the upper air outlet 11, and / or the second air guide 62 opens downwards from the upper air outlet 11, thereby opening the upper air outlet 11. Furthermore, in this embodiment, the opening angles of the first air guide 61 and / or the second air guide 62 can be adjusted to achieve different air outlet states of the upper air outlet 11.

[0060] The first air guide 61 and the second air guide 62 can be controlled independently or simultaneously to achieve flexible adjustment of the air outlet area and / or air outlet direction of the upper air outlet 11, so as to further improve the indoor temperature regulation effect.

[0061] In one alternative implementation, when the upper air outlet 11 is in the air-discharging state, at least one of the first air guide 61 and the second air guide 62 can be controlled to be in different open positions to adjust the air-discharging state of the upper air outlet 11, and the air volume and / or air direction of the upper air outlet 11 are different in different air-discharging states.

[0062] In one example, the upper air outlet 11 includes a first air outlet state, a second air outlet state, and a third air outlet state. Wherein: [Example 1] Figure 6 As shown, in the first air outlet state, both the first air guide 61 and the second air guide 62 open the upper air outlet 11 in a horizontal direction to achieve horizontal air outlet 11; as Figure 7 As shown, in the second air outlet state, both the first air guide 61 and the second air guide 62 open the upper air outlet 11 at an upward angle to achieve upward air outlet. Figure 8 As shown, in the third air outlet state, both the first air guide 61 and the second air guide 62 open the upper air outlet 11 in a downward tilted manner to achieve downward air outlet.

[0063] In practical applications, at least one of the indoor temperature, air conditioner operating mode, and air conditioner air outlet method can be combined with the open state of the first air guide 61 and the second air guide 62 to achieve air volume distribution and airflow path optimization, reduce energy loss, accelerate the uniformity of indoor temperature field, and thus improve energy efficiency.

[0064] In one alternative implementation, such as Figure 4 and Figure 5As shown, when the first air guide 61 and the second air guide 62 are closed at the upper air outlet 11, the first air guide 61 and the second air guide 62 have an overlapping area to maximize the length of the first air guide 61 and the second air guide 62, thereby improving the guiding effect of the first air guide 61 and the second air guide 62 on the airflow at the upper air outlet 11.

[0065] In one alternative implementation, such as Figures 1-8 As shown, the upper air guide assembly 6 also includes a third air guide 63, which is rotatably disposed inside the upper air outlet 11. The upper end of the third air guide 63 is rotatably connected to the inner top wall of the upper air outlet 11, and the lower end of the third air guide 63 is rotatably connected to the inner bottom wall of the upper air outlet 11. The third air guide 63 can adjust the airflow of the upper air outlet 11 in the left and right directions.

[0066] In one alternative implementation, such as Figures 1-8 As shown, a fan cavity 21 is formed within the first air duct section 2. The air conditioner also includes an air supply component 8 and an indoor heat exchanger 9. The air supply component 8 is rotatably disposed within the fan cavity 21, and the air supply component 8 can be a cross-flow fan. In this embodiment, airflow can be achieved through multiple air outlets using only one air supply component 8, effectively reducing energy consumption.

[0067] The indoor heat exchanger 9 is located between the air inlet and the first air duct section 2. The indoor heat exchanger includes a front end 91 and a rear end 92 arranged along the front-rear direction of the indoor unit housing 1. The front end 91 is connected to the rear part of the indoor unit housing 1, and the rear end 92 is located at the connection position between the first air duct section 2 and the second air duct section 3. The indoor heat exchanger 9 is arranged along the circumferential direction of the air supply component 8, and the front end 91 is sealed to the rear part of the indoor unit housing 1, and the rear end 92 is sealed to the first air duct section 2 and / or the second air duct section 3, so as to ensure that all the air inlet air is heat-exchanged by the indoor heat exchanger before entering the first air duct section 2.

[0068] In one optional implementation, both the first air duct section 2 and the second air duct section 3 are equipped with airflow detection devices (not shown in the figure). The airflow detection results of the airflow detection devices are used to adjust the position of the damper 4 when it is in the third position. Specifically, the ratio of the airflow in the first air duct section 2 to the second air duct section 3 is compared with a target value, and the position of the damper 4 is adjusted according to the comparison result to reasonably distribute the airflow between the first air duct section 2 and the second air duct section 3.

[0069] The technical solution of this embodiment will be described in detail below with reference to specific examples.

[0070] The wall-mounted air conditioner of this embodiment includes an indoor unit housing 1, a cross-flow fan, and sweeping blades 5. The indoor unit housing 1 is provided with an air inlet, an upper air outlet 11, and a lower air outlet 12. The air inlet and the lower air outlet 12 are connected through a first air duct section 2. The cross-flow fan is located in the first air duct section 2. The upper air outlet 11 and the lower air outlet 12 are connected to a second air duct section 3. A movable damper 4 is also provided between the first air duct section 2 and the second air duct section 3. By changing the position of the damper 4, the airflow from the upper air outlet 11 and the lower air outlet 12 can be controlled, and the air volume of the upper air outlet 11 and the lower air outlet 12 can also be adjusted.

[0071] The upper air outlet 11 is provided with an upper air guide assembly 6, and the lower air outlet 12 is provided with a lower air guide component 7. The upper air guide assembly 6 is used to open and close the upper air outlet 11 and adjust the air supply direction of the upper air outlet 11, and the lower air guide component 7 is used to adjust the air supply direction of the lower air outlet 12.

[0072] This embodiment disassembles the air outlet of the air conditioner into multiple air outlets. The ventilation door 4 adjusts the air outlet mode of the air conditioner. Under different air outlet modes, the air supply volume of the first air duct section 2 and the second air duct section 3 can be adjusted in real time to increase the air outlet range of the air conditioner and make the air conditioner generate periodic fluctuating air, thereby improving user comfort. Moreover, it is low in cost, simple in structure, convenient and practical.

[0073] like Figure 2 and Figure 3 As shown, when the damper 4 is in the second position, the damper 4 closes the passage between the second air duct section 3 and the lower air outlet 12, and opens the passage between the first air duct section 2 and the second air duct section 3, allowing all airflow to be sent out from the upper air outlet 11 through the second air duct section 3. At this time, the first air guide 61 and the second air guide 62 of the upper air guide assembly 6 open the upper air outlet 11, and the third air guide 63 swings left and right, controlling the airflow from the upper air outlet 11 to be sent left and right. When the first air guide 61 and the second air guide 62 are closed at the upper air outlet position, the angle between them and the front panel is 0°. When the first air guide 61 and the second air guide 62 are fully open at the upper air outlet 11, the angle between them and the front panel is 180°. Within this angle range, the first air guide 61 and the second air guide 62 can be independently controlled, thereby adjusting the airflow distance and angle at the upper air outlet and preventing airflow backflow.

[0074] For example, when the first air guide 61 and the second air guide 62 are in a horizontal state, the airflow resistance is small and the air volume is large, which is the conventional air supply mode.

[0075] The control logic of the upper air guide assembly 6 is as follows: after the upper air outlet is opened, the second air guide 62 first starts to move, opening to the 90° position. Then, the second air guide 62 moves again, opening to the 90° position. If a longer distance of air delivery is required, the two air guides need to be adjusted upwards. At this time, the upward increase angle of the first air guide 61 is the same as the upward decrease angle of the second air guide 62, ensuring that the two air guides are parallel and preventing inconsistent angles that would cause excessive changes in the air outlet area, thus affecting the air outlet resistance. For downward, short-distance air delivery, similar control is applied; that is, the downward increase angle of the second air guide 62 is equal to the downward decrease angle of the first air guide 61. The upward or downward adjustment angle range of the first air guide 61 and the second air guide 62 is 0~45°. Excessive angles will adversely affect the air outlet area and resistance. When the upper air outlet is closed, the first air guide 612 first returns to the 0° position, and then the second air guide 62 returns to the 0° position.

[0076] like Figure 4 and Figure 5 As shown, the damper 4 is in the first position, that is, the damper 4 closes the passage between the first air duct section 2 and the second air duct section 3, and opens the passage between the first air duct section 2 and the lower air outlet 12, so that all airflow is sent out through the lower air outlet 12. At this time, the lower guide fan is open to adjust the airflow direction of the lower air outlet 12.

[0077] like Figures 6-8 As shown, when the damper 4 is in the middle position, i.e. the third position, the passage between the first air duct 2 and the lower air outlet 12, as well as the passage between the first air duct 2 and the second air duct 3, will be opened simultaneously, so that the airflow is sent out from the lower air outlet 12 and the upper air outlet 11 at the same time.

[0078] When the air conditioner is running in cooling mode, the user can select the "top-discharge only" mode. The control system commands the motor to rotate the damper 4 to the desired position. Figure 2 and Figure 3 In the second position shown, all the cold air is forced into the second air duct 3 and blown out from the upper air outlet 11. The cold air can be guided to a horizontal, slightly upward or slightly downward direction by the upper air guide assembly 6. By utilizing the principle of natural sinking of cold air, it avoids blowing directly on the human body.

[0079] When the air conditioner is running in heating mode, the user can select the "single downward airflow" mode. The drive motor rotates the damper 4 to the desired position. Figure 4 and Figure 5 In the first position shown, all the hot air is blown out from the lower air outlet 12 and guided towards the ground or diagonally forward and downward by the lower air guide 7. By utilizing the principle of hot air rising, the temperature of the lower part of the room is quickly increased, solving the problem of "hot head and cold feet".

[0080] The above air supply methods are the default conventional air supply methods. Users can also set the cooling and heating modes and the air supply methods of the vents according to their own needs.

[0081] When the air conditioner is running in comfort / fast mode, the user can select the "simultaneous airflow from top and bottom" mode, which will drive the motor to rotate the damper 4 to the desired position. Figures 6-8 In the third position shown (middle position), the airflow is divided into two parts and sent out from the upper air outlet 11 and the lower air outlet 12 at the same time. This can form a more complex and efficient airflow circulation in the room, quickly balance the temperature of the entire space, and achieve a gentle breeze effect without wind.

[0082] Under normal circumstances, in the simultaneous upper and lower air outlet mode, uneven airflow may occur due to differences in duct resistance, affecting comfort. Furthermore, in this embodiment, the upper air guide component 6 has a large movement angle and a significant impact on the resistance of the air outlet. Therefore, this embodiment provides a cleverly structured indoor unit of a dual-outlet single-flow air conditioner with both upper and lower air outlets that can dynamically balance the airflow volume of the upper and lower outlets, improving comfort, and its control method. To achieve this control method, the key components are: a drive device connected to the damper 4 for driving its continuous rotation; a controller electrically connected to the drive device; and two airflow detection devices disposed in the first duct section 2 and the second duct section 3, electrically connected to the controller. The controller is configured to, when the damper 4 is in the third position, control the drive device to fine-tune the opening angle of the damper 4 based on feedback signals from the airflow detection devices, so as to dynamically balance the airflow volume and pressure of the upper air outlet 11 and the lower air outlet 12.

[0083] Furthermore, the air volume detection device is a wind pressure sensor or a wind speed sensor.

[0084] Furthermore, the controller's control logic is a closed-loop feedback control algorithm, such as a PID control algorithm. The controller sets a target airflow ratio K and compares the detected actual airflow value with the target value in real time, calculates the error, and then outputs a control signal to the drive device to drive the damper 4 to fine-tune the angle in the direction of reducing the error until the actual airflow ratio stabilizes near the target value.

[0085] This embodiment also provides a control method for the indoor unit of the above-mentioned air conditioner, referring to... Figure 9 The flowchart includes the following steps: S1: Receives user command to enter the simultaneous airflow mode from top and bottom; S2: The controller controls the drive unit to initially position the damper 4 to a preset intermediate angle position; S3: The actual air volume values ​​Q2 and Q1 of the second air duct section 3 and the first air duct section 2 are collected in real time by the air volume detection device; S4: The controller calculates the actual air volume ratio (Q2 / Q1) and compares it with the preset target air volume ratio K; S5: If the actual air volume ratio deviates from the target air volume ratio K, the controller generates an adjustment signal to drive the damper 4 to make a small angle deflection (such as ±2°) to change the inlet opening area and resistance distribution of the first air duct section 2 and the second air duct section 3. S6: Repeat steps S3-S5 until the actual air volume ratio stabilizes within the target range, achieving a dynamic balance between the upper and lower air volumes.

[0086] The target airflow ratio K can be set according to different operating scenarios: Cooling mode: The target K value can be set to <0.9, that is, the downward airflow is slightly greater than the upward airflow, promoting the natural sinking of cold air and avoiding direct cold air blowing. Heating mode: The target K value can be set to >1.1, that is, the upward airflow is slightly greater than the downward airflow, preventing all hot air from sinking and facilitating the diffusion of hot air. Comfort mode: The target K value can be set to 0.9 to 1.1, enhancing the robustness of the method, achieving a balance between upward and downward airflow, and creating a uniform and gentle airflow environment.

[0087] Through dynamic airflow balancing technology (closed-loop feedback control algorithm) and intelligent control of the air guide plate, the directional delivery of hot and cold air is achieved (cold air sinks when cooling and hot air rises when heating), effectively avoiding direct airflow onto the human body, solving temperature stratification problems such as "hot head and cold feet", and significantly improving user comfort.

[0088] It adopts a coordinated air supply mode with 12 upper and lower air outlets to form a complex airflow circulation, enhance the "windless" soft wind effect, and reduce the discomfort caused by airflow short-circuiting (direct mixing of hot and cold air).

[0089] This embodiment uses closed-loop feedback control (such as PID algorithm) to monitor the air volume of the first air duct section 2 and the second air duct section 3 in real time, and dynamically adjusts the angle of the damper 4 to adapt to actual working conditions such as filter blockage and changes in indoor pressure, so as to ensure stable air volume ratio and improve system robustness.

[0090] This embodiment supports intelligent switching of multiple scene air supply modes (cooling, heating, comfort / fast mode) to meet users' personalized needs and enhance product adaptability.

[0091] This embodiment reduces energy loss and accelerates the homogenization of the indoor temperature field by precisely distributing airflow and optimizing the airflow path, thereby indirectly improving energy efficiency.

[0092] In this embodiment, the single air supply component 8 is designed to reduce energy consumption and avoid the additional power consumption of dual fans or complex air duct systems, thus achieving high efficiency and energy saving.
