Description

Technical Field

[0001] This application relates to the field of air conditioning technology, and more specifically, to a method, device and air conditioner for controlling an air deflector. Background Technology

[0002] Existing air conditioners can achieve air swing function through a rotating air deflector, and the air outlet can also be closed through the air deflector. However, after the existing air conditioner is turned off, the fan stops rotating, and the airflow speed drops rapidly. Users may feel abruptly because the airflow disappears quickly, resulting in a poor user experience. Summary of the Invention

[0003] The problem addressed in this application is the abrupt disappearance of the airflow after the air conditioner is turned off, which results in a poor user experience.

[0004] To address the aforementioned problems, in a first aspect, this application provides a method for controlling an air deflector, applied to an air conditioner. The air conditioner includes a first air deflector and a second air deflector disposed at the air outlet and rotatable. The first and second air deflectors are used to execute commands to adjust the air outlet direction or open / close the air outlet by rotation. The air deflector control method includes:

[0005] Receive shutdown command;

[0006] Control the first air guide damper to rotate to the first transition position, and control the second air guide damper to rotate to the second transition position, so that a gradually narrowing air outlet channel is formed between the first air guide damper and the second air guide damper;

[0007] Control the first and second air guide dampers to rotate until the air outlet is closed.

[0008] The air deflector control method provided in this application allows the first and second air deflectors to jointly form a gradually narrowing air outlet channel after the air conditioner receives a shutdown command, thus creating a concentrated airflow effect. Therefore, even as the fan speed and overall airflow gradually decrease, the air velocity does not drop too quickly after passing through the narrowing air outlet channel, preventing the airflow from disappearing too rapidly and reducing the abrupt feeling of sudden airflow loss for the user, thereby improving the user experience.

[0009] In an optional embodiment, the first air guide damper has a first closed position during its rotation stroke, and the second air guide damper has a second closed position during its rotation stroke. The step of controlling the first and second air guide dampers to rotate to close the air outlet includes:

[0010] The first air guide damper is controlled to rotate from the first transition position to the first closed position along the first rotation direction, and the second air guide damper is controlled to rotate from the second transition position to the second closed position along the second rotation direction, wherein the first rotation direction is opposite to the second rotation direction;

[0011] And / or, the step of controlling the first air guide damper to rotate to a first transition position and controlling the second air guide damper to rotate to a second transition position, so as to form a gradually narrowing air outlet channel between the first air guide damper and the second air guide damper, includes:

[0012] Control the first air guide door to rotate from its current position along the second rotation direction to the first transition position, and control the second air guide door to rotate from its current position along the first rotation direction to the second transition position.

[0013] By using different rotation directions to close the first and second air guide doors, or by using different rotation directions to control the first and second air guide doors to rotate to the first and second transition positions respectively, the air conditioner can be made more symmetrical in structure and control method.

[0014] In an optional embodiment, during the process of controlling the first and second air guide dampers to rotate to close the air outlet, the first air guide damper is first controlled to rotate from a first transition position along a first rotation direction to a first closed position, and then the second air guide damper is controlled to rotate from a second transition position along a second rotation direction to a second closed position, so that the edge of the second air guide damper overlaps with the inner side of the edge of the first air guide damper. By closing the first and second air guide dampers sequentially, the edge of the second air guide damper can overlap with the inner side of the edge of the first air guide damper, which can improve the sealing performance of the first and second air guide dampers when closing the air outlet, better isolate the inside and outside of the air conditioner, and improve the protection of the internal components of the air conditioner.

[0015] In an optional implementation, the rotation angle of the first air guide damper from the first transition position to the first closed position is equal to the rotation angle of the second air guide damper from the second transition position to the second closed position. This arrangement ensures that the air outlet channel formed by the first air guide damper in the first transition position and the second air guide damper in the second transition position faces directly in front of the air outlet. Since the area directly in front of the air outlet is typically the user's active area, this significantly improves the user experience.

[0016] In an optional embodiment, the rotation angle of the first air guide damper from the first transition position to the first closed position is 110° to 130°.

[0017] And / or, the rotation angle of the second air guide damper from the second transition position to the second closed position is 110° to 130°. By setting the above rotation angle, it can be ensured that the first air guide damper and the second air guide damper rotate from the position where they jointly form a narrowing air outlet channel to the position where the air outlet is closed.

[0018] In an optional implementation, the air conditioner has a swing mode, in which the first air guide damper has a first swing limit position in the second rotation direction, and the second air guide damper has a second swing limit position in the first rotation direction.

[0019] The first transition position is further deflected by a first difference angle in the second rotation direction relative to the first sweep limit position;

[0020] The second transition position is further deflected by a second difference angle relative to the second sweep limit position in the first swirl direction.

[0021] By adopting the above configuration, the air gathering effect of the gradually narrowing air outlet channel formed by the first and second air guides can be further improved, thereby better reducing the rate of airflow attenuation and improving the user experience.

[0022] In an optional implementation, the first difference angle and / or the second difference angle is 5° to 15°.

[0023] In an optional embodiment, when the first air guide damper is in the first transition position and the second air guide damper is in the second transition position, the included angle between the first air guide damper and the second air guide damper is 60° to 80°. By setting the included angle between the first air guide damper and the second air guide damper to 60° to 80°, a better air concentration effect can be achieved.

[0024] Secondly, this application provides an air guide damper control device applied to an air conditioner. The air conditioner includes a first air guide damper and a second air guide damper disposed at the air outlet and rotatable. The first air guide damper and the second air guide damper are used to adjust the air outlet direction by rotation and to jointly close the air outlet. The air guide damper control device includes:

[0025] The receiving module is used to receive power-off commands;

[0026] The air-gathering module is used to control the first air guide door to rotate to the first transition position and the second air guide door to rotate to the second transition position, so that a gradually narrowing air outlet channel is formed between the first air guide door and the second air guide door.

[0027] The reset module is used to control the rotation of the first and second air guide dampers to close the air outlet.

[0028] Thirdly, this application provides an air conditioner including a controller, which executes executable instructions to implement the air deflector control method of any of the foregoing embodiments. Attached Figure Description

Detailed Implementation

[0038] In existing air conditioning units, two air deflectors are used to control the airflow direction, and these deflectors can also act as baffles to close the air outlets when the unit is turned off. When the air conditioner receives a shutdown command, the two air deflectors rotate directly to the closed position. However, after the motor stops driving the fan blades, the fan speed drops rapidly, and the airflow decreases rapidly, which can cause users to experience a sudden loss of airflow, resulting in a poor user experience.

[0039] To address the issue of abrupt airflow loss in existing air conditioners upon shutdown, this application provides a method for controlling airflow deflectors. Upon receiving a shutdown command, the method first rotates two airflow deflectors to a transition position to achieve a concentrated airflow effect, maintaining or slowing the rate at which the airflow disappears. This prevents sudden loss of airflow, reduces abruptness, and improves the user experience. Furthermore, this application also provides an airflow deflector control device and an air conditioner for implementing the aforementioned airflow deflector control method.

[0040] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, specific embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0041] Figure 1This is a schematic diagram of an air conditioner 010 in one embodiment of this application when the air outlet 101 is closed; Figure 2 This is a schematic diagram showing the state of the air conditioner 010 at a certain moment during the air sweeping process in one embodiment of this application. Figure 1 and Figure 2 As shown, the air conditioner 010 provided in this embodiment includes a housing 100, a fan 200, and an air guiding mechanism. In this embodiment, the fan 200 is a cross-flow fan 200, disposed within the housing 100. The housing 100 is provided with an air outlet 101 for discharging air, which faces the front of the air conditioner 010. The air guiding mechanism includes a first air guide damper 300 and a second air guide damper 400 disposed at the air outlet 101 and capable of independent rotation. The first air guide damper 300 and the second air guide damper 400 are used to adjust the airflow direction by rotation and to jointly close the air outlet 101. It can be understood that by rotating the first air guide damper 300 and the second air guide damper 400, an air outlet channel 102 can be formed between the first air guide damper 300 and the second air guide damper 400. The airflow delivered by the fan 200 can be sent out of the air conditioner 010 along the air outlet channel 102. The orientation of the air outlet channel 102 is determined by the attitude of the first air guide damper 300 and the second air guide damper 400, and the orientation of the air outlet channel 102 determines the air outlet direction. Therefore, by dynamically controlling the rotation of the first air guide damper 300 and the second air guide damper 400, the air conditioner 010 can be swept in one direction.

[0042] This embodiment uses a floor-standing air conditioner (010) as an example. The air conditioner 010 in this embodiment has a swing mode. In this mode, the first air guide door 300 and the second air guide door 400 reciprocate within their respective rotation strokes, thus achieving left-right swing function. In other optional embodiments, the air conditioner 010 can also be a wall-mounted air conditioner, which can achieve up-down swing by controlling the rotation of the first air guide door 300 and the second air guide door 400.

[0043] Specifically, in this embodiment, the first air guide door 300 is the air guide door on the right side of the figure, and the second air guide door 400 is the air guide door on the left side of the figure.

[0044] In this embodiment, the first air guide damper 300 and the second air guide damper 400 can each be driven by two independent motors, and the rotation axes of the first air guide damper 300 and the second air guide damper 400 can be symmetrically arranged with respect to a central symmetry plane. It should be understood that the aforementioned central symmetry plane is a virtual plane, which is parallel to the front direction of the air conditioner 010 (that is, the direction directly opposite the air outlet 101).

[0045] In this embodiment, the first air guide damper 300 and the second air guide damper 400 have a first closed position and a second closed position respectively during their respective rotation strokes. Figure 1In this embodiment, the first air guide damper 300 is in the first closed position, and the second air guide damper 400 is in the second closed position. At this time, the first air guide damper 300 and the second air guide damper 400 together close the air outlet 101. In this embodiment, the first air guide damper 300 and the second air guide damper 400 have outer surfaces. When the air outlet 101 is closed, the outer surfaces of the first air guide damper 300 and the second air guide damper 400 face the outside of the air conditioner 010. When the first air guide damper 300 and the second air guide damper 400 form the air outlet channel 102, the outer surfaces face the air outlet channel 102. In this embodiment, the overall shape of the air conditioner 010 is cylindrical; therefore, the outer surfaces of the first air guide damper 300 and the second air guide damper 400 can be curved surfaces to improve the aesthetics of the air conditioner 010 when the air outlet 101 is closed. In other optional embodiments, the outer surfaces of the first air guide damper 300 and the second air guide damper 400 can also be flat.

[0046] Furthermore, when the first air guide damper 300 and the second air guide damper 400 jointly close the air outlet 101, the edge of the second air guide damper 400 overlaps with the inner side of the edge of the first air guide damper 300. This reduces the gap between the first air guide damper 300 and the second air guide damper 400, thereby improving the sealing performance and preventing external foreign objects, dust, and other impurities from entering the air conditioner 010 when it is not in use. Optionally, a sealing element can be provided at the overlapping part of the first air guide damper 300 and the second air guide damper 400 to further improve the sealing performance. The sealing element can be provided at the edge of the first air guide damper 300 and / or the second air guide damper 400. It should be understood that in other optional embodiments, when the first air guide damper 300 and the second air guide damper 400 jointly close the air outlet 101, their edges may not overlap, but rather abut against each other or leave a certain gap in the width direction of the air outlet 101.

[0047] Figure 3 This is a flowchart of a deflector control method in one embodiment of this application. Figure 3 As shown, the air deflector control method provided in this application embodiment can be applied to the air conditioner 010 described above. The air deflector control method includes:

[0048] Step S100: Receive power-off command.

[0049] In this embodiment of the application, the shutdown command can be manually entered by the user through the remote control or the control panel on the air conditioner 010, or it can be generated by the air conditioner 010 itself after certain conditions (such as timer conditions or temperature conditions) are met.

[0050] In step S200, the first air guide door 300 is controlled to rotate to the first transition position, and the second air guide door 400 is controlled to rotate to the second transition position, so that a gradually narrowing air outlet channel 102 is formed between the first air guide door 300 and the second air guide door 400.

[0051] Figure 4 This is a schematic diagram of an air conditioner 010 in a concentrated airflow state according to one embodiment of this application. In this embodiment, the tapered air outlet channel 102 specifically refers to the width of the end of the air outlet channel 102 near the outside of the air conditioner 010 being smaller than the width of the end of the air outlet channel 102 near the inside of the air conditioner 010. In other words, the cross-sectional area of ​​the tapered air outlet channel 102 gradually decreases along the air outlet path. It can be understood that the first transition position and the second transition position are specific positions of the first air guide damper 300 and the second air guide damper 400 during their respective rotational strokes, specifically designed to make the air conditioner 010 exhibit a concentrated airflow state.

[0052] In this embodiment, the first air guide damper 300 and the second air guide damper 400 together form a gradually narrowing air outlet channel 102, thereby achieving a wind-gathering effect. Therefore, even after receiving a shutdown command, the fan speed and overall air volume decrease rapidly, but the wind speed will not decrease too quickly after passing through the gradually narrowing air outlet channel 102. As a result, the wind sensation will not disappear too quickly, and users are less likely to experience abruptness due to the sudden disappearance of the wind sensation, thus improving the user experience.

[0053] Optionally, when the first air guide damper 300 is in the first transition position and the second air guide damper 400 is in the second transition position, the angle between the first air guide damper 300 and the second air guide damper 400 is 60° to 80°. By setting the angle between the first air guide damper 300 and the second air guide damper 400 to 60° to 80°, a better air concentration effect can be achieved.

[0054] In step S300, control the first air guide door 300 and the second air guide door 400 to rotate to close the air outlet 101.

[0055] In this embodiment, step S300 may specifically include: controlling the first air guide damper 300 to rotate from a first transition position along a first rotation direction to a first closed position, and controlling the second air guide damper 400 to rotate from a second transition position along a second rotation direction to a second closed position, wherein the first rotation direction is opposite to the second rotation direction. By closing the first air guide damper 300 and the second air guide damper 400 through different rotation directions, the air conditioner 010 becomes more symmetrical in structure and control method. Figure 4 In the first rotation direction is counterclockwise, so by rotating the first air guide 300 counterclockwise, it is rotated from the first transition position to the first closed position; the second rotation direction is clockwise, so by rotating the second air guide 400 clockwise, it is rotated from the second transition position to the second closed position.

[0056] Figure 5 This is a schematic diagram showing the first air guide door 300 rotating towards the first closed position in one embodiment of this application; Figure 6 This is a schematic diagram showing the first air guide damper 300 rotating to the first closed position in one embodiment of this application. Figure 5 and Figure 6 As shown, in this embodiment, during the process of controlling the first air guide damper 300 and the second air guide damper 400 to rotate to close the air outlet 101, the first air guide damper 300 is first controlled to rotate from the first transition position along the first rotation direction to the first closed position, and then the second air guide damper 400 is controlled to rotate from the second transition position along the second rotation direction to the second closed position, so that the edge of the second air guide damper 400 overlaps the inner side of the edge of the first air guide damper 300, resulting in the following... Figure 1 The state shown is as follows. By closing the first air guide damper 300 and the second air guide damper 400 sequentially, the edge of the second air guide damper 400 can overlap the inner side of the edge of the first air guide damper 300. This improves the sealing performance of the first air guide damper 300 and the second air guide damper 400 when closing the air outlet 101, better isolating the interior and exterior of the air conditioner 010, and enhancing the protection of the internal components of the air conditioner 010. Furthermore, closing the first air guide damper 300 first and then the second air guide damper 400 can also avoid mutual interference when the two air guide dampers close simultaneously.

[0057] In this embodiment, the rotation angle of the first air guide damper 300 from the first transition position to the first closed position is equal to the rotation angle of the second air guide damper 400 from the second transition position to the second closed position. This arrangement ensures that the air outlet channel 102 formed by the first air guide damper 300 in the first transition position and the second air guide damper 400 in the second transition position faces directly in front of the air outlet 101. Since the area directly in front of the air outlet 101 is typically the user's active area, this significantly improves the user experience.

[0058] Optionally, the rotation angle of the first air guide damper 300 from the first transition position to the first closed position is 110° to 130°; and / or, the rotation angle of the second air guide damper 400 from the second transition position to the second closed position is 110° to 130°. By setting the above rotation angles, it can be ensured that the first air guide damper 300 and the second air guide damper 400 rotate from the position where they jointly form the narrowing air outlet channel 102 to the position where the air outlet 101 is closed.

[0059] In this embodiment, the air conditioner 010 has a swing mode. In the swing mode, the first air guide damper 300 and the second air guide damper 400 reciprocate to achieve left and right swing. It should be understood that the swing mode can be performed in conjunction with the cooling mode and the heating mode. In the swing mode, the first air guide damper 300 has a first swing limit position in the second rotation direction, and the second air guide damper 400 has a second swing limit position in the first rotation direction. In other words, in the swing mode, the first air guide damper 300 can rotate at most to the first swing limit position in the second rotation direction (corresponding to the clockwise direction in the figure), at which point the air outlet direction of the air conditioner 010 is furthest to the left; while the second air guide damper 400 can rotate at most to the second swing limit position in the first rotation direction (corresponding to the counterclockwise direction in the figure), at which point the air outlet direction of the air conditioner 010 is furthest to the right. Optionally, the limit position of the first air guide damper 300 in the first rotation direction is the first closed position, and the limit position of the second air guide damper 400 in the second rotation direction is the second closed position.

[0060] In this embodiment, the first sweep limit position is not the limit position that the first air guide damper 300 can rotate to in the second rotation direction, and the second sweep limit position is not the limit position that the second air guide damper 400 can rotate to in the first rotation direction. Therefore, the step S200 of controlling the first air guide damper 300 to rotate to the first transition position and controlling the second air guide damper 400 to rotate to the second transition position, so as to form a gradually narrowing air outlet channel 102 between the first air guide damper 300 and the second air guide damper 400, may specifically include: controlling the first air guide damper 300 to rotate from its current position along the second rotation direction to the first transition position, and controlling the second air guide damper 400 to rotate from its current position along the first rotation direction to the second transition position. In this embodiment, the first transition position is further deflected by a first differential angle relative to the first sweep limit position in the second rotation direction; the second transition position is further deflected by a second differential angle relative to the second sweep limit position in the first rotation direction. By adopting the above configuration, the air gathering effect of the gradually narrowing air outlet channel 102 formed by the first air guide door 300 and the second air guide door 400 can be further improved, thereby better reducing the wind feel attenuation rate and improving the user experience.

[0061] Optionally, the first differential angle and / or the second differential angle are 5° to 15°, for example, 10°. In other words, if the deflection angle of the first sweep limit position relative to the first closed position in the second rotation direction is 110°, then the deflection angle of the first transition position relative to the first closed position in the second rotation direction is 115° to 125°.
