Traditional air conditioners, especially floor-standing units, cannot completely solve the problem of direct cold air blowing; they can only prevent cold air from blowing directly onto people by adjusting the angle of the air deflector. Existing air conditioners with circular air outlets have limited air outlet angles. To achieve larger angle adjustments, it would undoubtedly increase assembly complexity, manufacturing costs, and maintenance difficulties, failing to meet people's diverse air outlet needs.

[0021] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0022] The terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of this disclosure described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0023] Unless otherwise stated, the term "multiple" means two or more.

[0024] Combination Figure 1-4 As shown, this embodiment of the present disclosure provides an indoor unit for an air conditioner, including a housing 100 and a jetting device 200. The housing 100 includes an air outlet 101; the jetting device 200 is movably disposed on one side of the air outlet 101 and includes a jetting port 201, which is configured to be angle-adjustable.

[0025] The indoor unit of the air conditioner provided in this embodiment has a jet device 200 on one side of the air outlet 101. The jet device 200 has an adjustable jet port 201. By adjusting the angle of the jet port 201, the air outlet direction of the jet is changed, thereby changing the air outlet direction of the entire air outlet 101. The jet device 200 can adjust the overall air outlet direction of the indoor unit of the air conditioner, so that the indoor unit of the air conditioner has a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0026] Optionally, the jetting device 200 further includes a power unit 300. The power unit 300 is connected to the jetting device 200 and is used to drive the jetting device 200 to adjust its distance from the air outlet 101. This allows the distance between the jetting device 200 and the air outlet 101 to be adjusted, thereby adjusting the overall airflow of the indoor unit of the air conditioner. This enables the indoor unit to have various airflow modes to meet diverse user needs. It is understood that when the jetting device 200 moves closer to the air outlet 101, it will obstruct the airflow from the air outlet 101 to some extent, thus reducing the airflow. Conversely, when the jetting device 200 moves away from the air outlet 101, it allows for unobstructed airflow from the air outlet 101, increasing the airflow.

[0027] Optionally, the jet outlet 201 is a rotatable nozzle mounted on the jet device 200. In this way, by rotating the nozzle, the angle of the jet is changed, thereby changing the air outlet direction of the entire air outlet 101, enabling the indoor unit of the air conditioner to have a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0028] In some embodiments, the jet device 200 includes a jet channel 202 and a rotating part 203. The rotating part 203 is rotatably connected to one end of the jet channel 202 and closes that end; wherein a jet port 201 is provided on the rotating part 203. In this way, the rotating part 203 blocks one end of the jet channel 202, and the jet port 201 is provided on the rotating part 203. The rotating part 203 can rotate with the rotating part 203, so that the airflow in the jet channel 202 flows out through the jet port 201. The direction of the jet changes with the rotation of the rotating part 203, thereby driving the change of the overall air outlet of the indoor unit of the air conditioner, so that the indoor unit of the air conditioner has a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0029] Optionally, the jet channel 202 is a retractable structure. This ensures that the rotating part 203 of the jet device 200 remains connected to the jet channel 202 even when its position changes, and keeps the air inlet position of the jet channel 202 stable, thereby improving the stability of the air intake of the jet channel 202.

[0030] Optionally, the air outlet 101 is circular, and the end of the rotating part 203 facing the air outlet 101 is also circular. This allows the rotating part 203 to fit snugly against the air outlet 101, creating a ring-shaped airflow effect as the airflow passes through the rotating part 203 and exits through the air outlet 101. Compared to a direct circular airflow, this results in a longer delivery distance, improving the airflow efficiency of the indoor unit. Furthermore, the ring-shaped airflow is more susceptible to the influence of the jet airflow, which facilitates a shift in the direction of the airflow from the indoor unit. This allows the indoor unit to offer a variety of airflow modes, meeting diverse user needs.

[0031] Optionally, the circular structure has an arc-shaped surface that bulges towards the air outlet 101. This allows the circular structure of the jet device 200 to better fit the air outlet 101, with the center of the circular structure bulging towards the air outlet 101, thus guiding the airflow and making the airflow at the air outlet 101 smoother. This creates a ring-shaped airflow pattern, increases the air delivery distance, and provides a better airflow effect. Furthermore, it improves the sealing effect of the jet device 200 when it approaches and closes the air outlet 101.

[0032] Optionally, the power unit 300 includes a screw rod 301 and a motor 302. The screw rod 301 is threadedly connected to the jetting device 200; the motor 302 is connected to the screw rod 301 and drives the screw rod 301 to rotate, thereby causing the jetting device 200 to move along the length of the screw rod 301. In this way, the motor 302 drives the screw rod 301 to rotate, thereby causing the jetting device 200 sleeved on the screw rod 301 to move along the screw rod 301 under the rotation of the screw rod 301, changing the position of the jetting device 200. When the jetting device 200 is close to the air outlet 101, it will obstruct the airflow from the air outlet 101 to a certain extent, thereby reducing the airflow volume; when the jetting device 200 is far away from the air outlet 101, it can allow the air outlet 101 to discharge air smoothly and increase the airflow volume. By adjusting the gap between the jet device 200 and the air outlet 101, the air volume of the air outlet 101 can be adjusted, thereby enabling the indoor unit of the air conditioner to have a variety of air outlet modes to meet people's diverse needs for air outlet modes.

[0033] Optionally, one end of the helical rod 301 is connected to the inner wall of the housing 100 via a bearing. This keeps the position of the helical rod 301 fixed and allows it to rotate freely, so that the jet device 200 can move smoothly along the helical rod 301 under the rotation of the helical rod 301.

[0034] Optionally, the spiral rod 301 is arranged perpendicular to the plane where the air outlet 101 is located. In this way, the jet device 200, which moves along the spiral rod 301, can move perpendicular to the air outlet 101, so that the jet device 200 can better guide the airflow towards the air outlet 101 and improve the air outlet effect.

[0035] Optionally, the jetting device 200 is provided with a first connecting hole 303, which is sleeved on the spiral rod 301, and the first connecting hole 303 is provided with an internal thread. In this way, the jetting device 200 can be stably connected to the spiral rod 301 through the threaded connection structure, and the threaded structure can better drive the movement of the jetting device 200.

[0036] Optionally, the power unit 300 further includes a slide rail 304. The slide rail 304 is parallel to the screw rod 301 and symmetrically arranged about the jetting device 200, with the jetting device 200 mounted on the slide rail 304. This confines the jetting device 200 to slide on the slide rail 304, thereby improving the stability of the movement of the jetting device 200 and allowing for better adjustment of its position.

[0037] Optionally, a second connecting hole 305 is provided on the jet device 200 at a position symmetrical to the first connecting hole 303, and the slide rail 304 passes through the second connecting hole 305. In this way, the slide rail 304 and the screw rod 301 are installed symmetrically, and the jet device 200 is confined to slide on the slide rail 304, thereby improving the stability of the movement of the jet device 200 and better adjusting the position of the jet device 200.

[0038] Optionally, a sliding bushing is provided inside the second connecting hole 305. This reduces the friction between the slide rail 304 and the second connecting hole 305, resulting in less resistance to movement of the jet device 200 and more stable movement.

[0039] Optionally, the jet device 200 further includes a drive device 400. The drive device 400 is connected to the rotating part 203 and is configured to drive the rotating part 203 to rotate. In this way, the drive device 400 provides power to the rotating part 203, so that the jet port 201 can rotate with the rotating part 203. As a result, when the airflow in the jet channel 202 is ejected through the jet port 201, the direction of the jet changes with the rotation of the rotating part 203, thereby changing the overall air outlet direction of the indoor unit of the air conditioner.

[0040] Optionally, the drive device 400 includes: an annular gear 401, a gear 402, and a drive motor 403. The annular gear 401 is fixedly connected to the side of the rotating part 203 facing the jet channel 202, the gear 402 meshes with the annular gear 401, and the output shaft of the drive motor 403 is connected to the gear 402. In this way, the gear 402 rotates under the drive of the drive motor 403. Through the meshing structure between the gear 402 and the annular gear 401, the annular gear 401 is driven to rotate, which in turn drives the rotating part 203 to rotate. The drive is more direct and efficient. Furthermore, under the drive of the drive device 400, the position of the jet port 201 on the rotating part 203 changes accordingly, thereby changing the direction of the airflow ejected from the jet port 201, enabling the jet port 201 to discharge air in multiple directions.

[0041] Combination Figure 5 As shown in the figure, this disclosure provides a method for controlling an indoor unit of an air conditioner, including:

[0042] S01, Determine the user's location;

[0043] S02, control the rotation angle of the jet nozzle according to the user's position.

[0044] The method for controlling an indoor unit of an air conditioner provided in this embodiment involves setting a jet device on one side of the air outlet. The jet device has an adjustable jet nozzle. By adjusting the angle of the jet nozzle, the air outlet direction of the jet is changed, thereby changing the air outlet direction of the entire air outlet. The angle of the jet nozzle is controlled according to the user's position, thereby controlling the air outlet direction. By changing the jet angle, the air conditioner can have a variety of air outlet directions, meeting people's diverse needs for the air outlet direction of the indoor unit of the air conditioner.

[0045] Optionally, controlling the rotation angle of the jet outlet according to the user's position includes: determining the air outlet mode of the indoor unit of the air conditioner; and controlling the rotation angle of the jet outlet according to the user's position and the air outlet mode of the indoor unit of the air conditioner. In this way, the air outlet demand can be determined based on the air outlet mode of the indoor unit of the air conditioner, thereby allowing for better adjustment of the jet outlet rotation angle according to the user's position to meet different air outlet needs.

[0046] Optionally, the air outlet mode of the indoor unit of the air conditioner includes: avoidance mode and blowing mode. This allows the air conditioner to be adjusted to either avoidance mode or blowing mode. In avoidance mode, the jet device changes the air outlet direction of the air conditioner, directing the airflow away from the user's location and creating a windless experience. In blowing mode, the jet device similarly changes the air outlet direction of the air conditioner, directing the airflow towards the user, allowing the user to feel the airflow and satisfying their need for ventilation, thus providing a better user experience.

[0047] Optionally, when the air outlet mode of the indoor unit of the air conditioner is in the avoidance mode, the angle of the jet nozzle is controlled to rotate towards the side opposite to the user's position. In this way, when the air outlet mode of the indoor unit is in the avoidance mode, controlling the jet nozzle to be positioned opposite the user's position allows the airflow to be directed towards the opposite side of the user's position, thus preventing the airflow from blowing directly on the user and providing a better, more draft-free experience. For example, if the user's position is to the left of the air outlet of the indoor unit when the air outlet mode of the indoor unit is in the avoidance mode, the jet nozzle will rotate to the right of the air outlet.

[0048] Optionally, when the air outlet mode of the indoor unit of the air conditioner is set to "blowing towards people," the angle of the jet nozzle is controlled to rotate towards the side where the user is located. In this way, when the air outlet mode is set to "blowing towards people," controlling the jet nozzle to be positioned towards the user allows the airflow to be directed towards the user's side, ensuring the airflow directly reaches the user and meets their cooling needs, providing a better user experience. For example, if the user is located to the left of the air outlet when the air outlet mode is set to "blowing towards people," the jet nozzle will rotate to the left of the air outlet.

[0049] Optionally, if the user is positioned directly in front of the air outlet of the indoor unit of the air conditioner, and the air outlet mode of the indoor unit is set to "avoidance mode," the angle of the jet nozzle can be rotated to the left or right. This way, when the user is directly in front of the air outlet, controlling the angle of the jet nozzle to rotate to the left or right avoids the user's location, preventing air from blowing directly on the user and creating a windless experience.

[0050] Optionally, the user is positioned directly in front of the air outlet of the indoor unit of the air conditioner, and the air outlet mode of the indoor unit is set to "blowing at people." The angle of the jet nozzle is then controlled to rotate upwards or downwards. This causes the jet of air blowing from the nozzle to deflect the airflow from the indoor unit upwards or downwards. Based on the characteristic that cold air sinks and hot air rises, when blowing cold air, the upward rotation of the jet nozzle ensures the cold air reaches the user as it sinks; conversely, when blowing hot air, the downward rotation of the jet nozzle ensures the hot air reaches the user as it rises, thus meeting the user's airflow needs and providing a better user experience.

[0051] Optionally, controlling the rotation angle of the jet outlet based on the user's location includes: determining the air outlet mode and operating mode of the indoor unit of the air conditioner; and controlling the rotation angle of the jet outlet based on the user's location, the air outlet mode of the indoor unit of the air conditioner, and the operating mode of the indoor unit of the air conditioner. In this way, the air outlet demand can be more accurately determined based on the air outlet mode and operating mode of the indoor unit of the air conditioner. Combining the air outlet demand with the user's location, the rotation angle of the jet outlet can be better adjusted according to the user's location to meet different air outlet needs.

[0052] Optionally, the operating modes of the air conditioner's indoor unit include: cooling mode and heating mode. In cooling mode, the air blown out by the indoor unit is cold air. Cold air has a sinking characteristic, so blowing it upwards achieves better airflow. Conversely, in heating mode, the air blown out by the indoor unit is hot air. Hot air has an upward characteristic, so blowing it downwards achieves better airflow. Therefore, considering the different airflow characteristics of the indoor unit in cooling and heating modes, the rotation angle of the jet nozzle can be better controlled, resulting in better airflow from the indoor unit.

[0053] Optionally, when the air conditioner's indoor unit is in the avoidance mode and the operating mode is cooling mode, the jet nozzle is rotated towards the upper half of the side facing the user's location. This positions the jet nozzle in the upper half of the side facing the user's location, causing the jet to direct the airflow from the nozzle towards the upper half of the area where the user is located. This avoids the user's location, providing a draft-free experience, and also shifts the airflow upwards, raising the cool air and improving the airflow efficiency.

[0054] Optionally, when the air conditioner's indoor unit is in the avoidance mode and the operating mode is heating mode, the jet nozzle is rotated towards the lower half of the area on the side opposite the user's location. This way, with the jet nozzle positioned in the lower half of the area facing the user, the jet from the nozzle drives the indoor unit's air outlet towards the lower half of the area opposite the user's location. This avoids the user's location, providing a draft-free experience, and also deflects the airflow downwards, blowing hot air downwards and improving airflow efficiency.

[0055] Optionally, when the air conditioner's indoor unit is in the air-blowing mode and the operating mode is cooling mode, the upper half of the jet nozzle is rotated towards the user's location. This positions the jet nozzle in the upper half of the side facing the user, causing the jet to direct the airflow from the nozzle towards the upper half of the user's location. This ensures the airflow reaches the user's location, meeting their cooling needs, while also shifting the airflow upwards, raising the cool air and improving the overall cooling effect.

[0056] Optionally, when the air conditioner's indoor unit is in the airflow mode of "blowing to people" and the operating mode is "heating," the jet nozzle is rotated to face the lower half of the area towards the user's location. This positions the jet nozzle in the lower half of the area facing the user, causing the jet to direct the airflow from the nozzle towards the lower half of the user's location. This ensures the airflow reaches the user's location, meeting their airflow needs, while also deflecting the airflow downwards, blowing hot air downwards and improving airflow efficiency.

[0057] Optionally, if the user is positioned directly in front of the air outlet of the indoor unit of the air conditioner, and the air outlet mode of the indoor unit is set to avoid people and the operating mode is set to cooling, the angle of the jet nozzle can be rotated towards the upper left or right side of the air outlet of the indoor unit. This rotation of the jet nozzle towards the upper left or right side of the air outlet causes the airflow from the jet nozzle to shift towards the upper left or right side of the air outlet, avoiding the user directly in front of the air outlet. Simultaneously, the upward airflow helps to raise the cool air, improving the airflow efficiency.

[0058] Optionally, if the user is positioned directly in front of the air outlet of the indoor unit of the air conditioner, and the air outlet mode of the indoor unit is set to avoid people and the operating mode is set to heating, the angle of the jet nozzle is controlled to rotate towards the lower half of the upper or lower side of the air outlet of the indoor unit. This rotation of the jet nozzle towards the lower half of the left or right side of the air outlet of the indoor unit causes the airflow from the jet nozzle to shift to the lower half of the left or right side of the air outlet, avoiding the user directly in front of the air outlet, and simultaneously directing the airflow downwards to blow hot air downwards, improving the airflow efficiency.

[0059] Optionally, the user is positioned directly in front of the air outlet of the indoor unit of the air conditioner, and the air outlet mode of the indoor unit is set to "blowing to people" and the operating mode is set to "cooling." The angle of the jet nozzle is then rotated upwards towards the air outlet of the indoor unit. This upward rotation of the jet nozzle causes the airflow from the jet nozzle to shift the airflow from the indoor unit upwards, raising the cool air and improving the airflow effect. Simultaneously, the descending cool air still meets the user's need for ventilation.

[0060] Optionally, the user is positioned directly in front of the air outlet of the indoor unit of the air conditioner, and with the air outlet mode set to "blowing to people" and the operating mode set to "heating," the angle of the jet nozzle is rotated downwards towards the air outlet of the indoor unit. This downward rotation of the jet nozzle causes the airflow from the jet nozzle to shift the airflow from the indoor unit downwards, blowing hot air downwards and improving the airflow efficiency. Simultaneously, the upward movement of the hot air still meets the user's need for ventilation.

[0061] Optionally, the method for controlling the indoor unit of the air conditioner further includes: controlling the air outlet speed of the jet device according to the user's position. Thus, when the jet device deflects the airflow from the air outlet, a higher air outlet speed results in a better deflection effect. Therefore, by controlling the air outlet speed of the jet device, the deflection angle of the airflow from the air outlet can be adjusted, thereby controlling the airflow to avoid or blow towards the user.

[0062] Optionally, controlling the airflow speed of the jet device according to the user's location further includes: determining the airflow mode of the indoor unit of the air conditioner; and controlling the airflow speed of the jet device according to the user's location and the airflow mode of the indoor unit of the air conditioner. In this way, based on the user's location and the airflow mode of the indoor unit of the air conditioner, the airflow speed of the jet device is adjusted according to the user's location in different airflow modes, so that the airflow avoids or blows towards the user.

[0063] Optionally, the airflow velocity of the jet device can be controlled based on the angle between the user's position and the central axis of the air outlet. In this way, the angle between the user's position and the central axis of the air outlet reflects the distance of the user's position from the center line of the air outlet, thereby controlling the airflow velocity of the jet device. This allows for better adjustment of the airflow velocity, ensuring that the airflow avoids or blows towards the user, thus improving the user experience.

[0064] Optionally, when the air conditioner's indoor unit is in the "blowing at people" mode, the larger the angle between the user's position and the central axis of the air outlet, the greater the air velocity of the jet device. Thus, the larger the angle between the user's position and the central axis of the air outlet, and the farther the user's position is from the air outlet of the indoor unit, increasing the air velocity of the jet device can increase the air outlet offset angle of the indoor unit, allowing the air to be blown more directly and effectively at the user, meeting their airflow needs.

[0065] Optionally, when the air conditioner's indoor unit is in the "avoidance mode" for airflow, the smaller the angle between the user's position and the central axis of the air outlet, the greater the airflow velocity of the jet device. Thus, the smaller the angle between the user's position and the central axis of the air outlet, the closer the user is to the front of the air outlet of the indoor unit. Increasing the airflow velocity of the jet device can increase the airflow deflection angle of the indoor unit, effectively avoiding the user and providing a draft-free experience.

[0066] Combination Figure 6 As shown in the embodiments of this disclosure, a method for controlling an air conditioner is provided, which further includes:

[0067] S03, determine the temperature difference between the indoor temperature and the set temperature;

[0068] S04, control the position of the jet device according to the temperature difference.

[0069] The method for controlling the indoor unit of an air conditioner provided in this embodiment involves a jetting device on one side of the air outlet, with an adjustable distance between the jetting device and the air outlet. The position of the jetting device is controlled based on the temperature difference between the indoor temperature and the set temperature. When the jetting device is close to the air outlet, it obstructs the airflow, thus reducing the air volume. When the jetting device is far from the air outlet, it allows for unobstructed airflow, increasing the air volume. The movable jetting device adjusts the overall air volume of the air conditioner, and the position between the jetting nozzle and the air outlet changes, thereby altering the overall airflow of the air conditioner and providing various airflow modes to meet diverse user needs.

[0070] Optionally, the greater the temperature difference, the farther the jetting device is from the air outlet. A larger temperature difference indicates a greater gap between the indoor temperature and the set temperature, meaning the indoor temperature is too high or too low. In this case, positioning the jetting device far from the air outlet can significantly increase the airflow from the outlet, thereby accelerating heating or cooling and quickly narrowing the gap between the indoor temperature and the set temperature. Conversely, a smaller gap indicates that the indoor temperature is closer to the set temperature. In this case, positioning the jetting device closer to the air outlet reduces the ventilation volume at the outlet, thus reducing energy consumption. By controlling the distance between the jetting device and the air outlet, the airflow volume can be controlled, increasing the diversity of airflow modes available in the air conditioner and meeting various needs for different airflow patterns.

[0071] Optionally, the change in temperature difference is directly proportional to the change in distance between the jet device and the air outlet. Thus, a larger temperature difference indicates a greater gap between the indoor temperature and the set temperature, meaning the indoor temperature is either too high or too low. In this case, positioning the jet device away from the air outlet can significantly increase the airflow, thereby accelerating heating or cooling, quickly narrowing the gap between the indoor temperature and the set temperature, improving the air conditioner's airflow efficiency, and offering diverse airflow modes to meet various user needs.

[0072] Optionally, for every 1 degree Celsius decrease in temperature difference, the distance between the jetting device and the air outlet decreases by 2 millimeters. This gradually reduces the distance between the jetting device and the air outlet as the temperature difference decreases, reducing the airflow from the air conditioner's outlet. This allows the air conditioner to cool or heat more smoothly, improving its energy efficiency. Furthermore, the 2-millimeter reduction in distance for every 1 degree Celsius decrease in temperature ensures that the change in temperature difference is proportional to the change in distance between the jetting device and the air outlet, improving the accuracy of airflow control and providing a better user experience.

[0073] Optionally, if the distance between the jet device and the air outlet is less than 10 mm, it will no longer change with temperature differences. This ensures that the air outlet maintains a minimum ventilation volume, guaranteeing normal airflow during air conditioning operation and enabling stable operation of the air conditioner.

[0074] Optionally, controlling the position of the jetting device based on the temperature difference includes: when the temperature difference is 0, the jetting device closes the air outlet; when the temperature difference is greater than or equal to a set threshold, the jetting device is positioned at a first set distance from the air outlet. Thus, when the temperature difference is 0, the jetting device can close the air outlet, preventing dust from entering. When the temperature difference is greater than or equal to the set threshold, it indicates a large difference between the indoor temperature and the set temperature. In this case, the air conditioner needs to cool or heat quickly. Adjusting the jetting device to the first set distance from the air outlet increases the distance between the jetting device and the air outlet, increasing the airflow and enabling the air conditioner to cool or heat quickly, thus improving the operating efficiency of the air conditioner.

[0075] Optionally, a threshold value can be set to be greater than or equal to 3 degrees Celsius and less than or equal to 5 degrees Celsius. Generally, the human body's sensitivity is lower when the temperature difference is less than 3 degrees Celsius, and higher when the temperature difference is greater than 5 degrees Celsius. A temperature difference exceeding 5 degrees Celsius indicates a large temperature difference, at which point the air conditioner needs to cool or heat quickly. Conversely, a temperature difference below 3 degrees Celsius indicates a small temperature difference, at which point the air conditioner only needs normal cooling or heating. Setting the threshold value between 3 and 5 degrees Celsius allows for more accurate control of the airflow from the outlet by adjusting the distance between the jet device and the outlet, resulting in more stable operation of the air conditioner.

[0076] Optionally, the threshold can be set to 5 degrees. With the threshold set to 5 degrees, when the temperature difference is greater than or equal to 5 degrees, it indicates a large temperature difference. In this case, the air conditioner needs to cool or heat quickly. The jet device is adjusted to a first set distance from the air outlet to maintain a large airflow, facilitating rapid cooling or heating and improving the efficiency of the air conditioner.

[0077] Optionally, the first set distance is greater than or equal to 35 mm and less than or equal to 45 mm. This controls the distance between the jet device and the air outlet to be between 35 and 45 mm. Within this distance, the airflow from the air outlet can be maintained within a large range. By increasing the airflow, the air conditioner can quickly cool or heat, thus improving its operating efficiency.

[0078] Optionally, the first set distance is 40 mm. In this way, at a distance of 40 mm from the air outlet, the airflow can flow out fully through the gap between the air outlet and the air jet device, maintaining a large airflow at the air outlet, thereby improving the operating efficiency of the air conditioner when rapid cooling or heating is required.

[0079] Optionally, the first set distance is greater than or equal to one-twelfth of the width of the air outlet and less than or equal to one-tenth of the width of the air outlet. This makes the distance between the jet device and the air outlet related to the width of the air outlet itself, allowing for better control of the actual airflow from the air outlet in conjunction with its maximum ventilation volume. When the temperature difference is greater than or equal to a set threshold, it indicates a large difference between the indoor temperature and the set temperature. In this case, the air conditioner needs to cool or heat quickly. Adjusting the distance between the jet device and the air outlet to between one-twelfth and one-tenth of the width of the air outlet allows the airflow from the air outlet to approach its maximum airflow, enabling the air conditioner to cool or heat quickly and improving its operating efficiency.

[0080] Optionally, the first set distance is equal to one-tenth of the width of the air outlet. In this way, when the temperature difference between the indoor temperature and the set temperature is greater than or equal to a set value, when the distance between the jet device and the air outlet is one-tenth of the width of the air outlet, the airflow can flow out fully through the gap between the jet device and the air outlet, maintaining that the air outlet can output air with a large airflow, thereby improving the operating efficiency of the air conditioner when it needs to cool or heat quickly.

[0081] Understandably, when the air outlet is rectangular, the width of the air outlet refers to the distance between its left and right sides; when the air outlet is circular, the width of the air outlet refers to the diameter of the air outlet.

[0082] Optionally, controlling the position of the jetting device based on the temperature difference further includes: when the temperature difference is greater than 0 and less than the set threshold, the jetting device is located at a second set distance from the air outlet. Thus, when the temperature difference is greater than 0 and less than the set threshold, it indicates that the difference between the indoor temperature and the set temperature is small. In this case, the air conditioner can operate smoothly in cooling or heating mode. Adjusting the jetting device to the second set distance from the air outlet ensures a suitable distance between the jetting device and the air outlet, maintaining the airflow from the air outlet within a suitable range. This maintains the stability of the airflow during normal cooling or heating, improving the overall stability of the air conditioner's airflow.

[0083] Optionally, the second set distance is greater than or equal to 20 mm and less than or equal to 30 mm. In this way, by controlling the distance between the jet device and the air outlet to be between 20 and 30 mm, the air volume of the air outlet can be kept within a moderate range within this distance, improving the stability of the air outlet of the air conditioner and maintaining the stability of the air volume during normal cooling or heating.

[0084] Optionally, the second set distance is 25 mm. In this way, when the distance between the jet device and the air outlet is 25 mm, the airflow through the gap between the jet device and the air outlet is more moderate, maintaining the stability of the airflow during normal cooling or heating, and improving the overall airflow stability of the air conditioner.

[0085] Optionally, the first set distance is greater than the second set distance. This way, when the temperature difference is greater than or equal to a set threshold, the distance between the jet device and the air outlet is greater; when the temperature difference is greater than 0 and less than or equal to the set threshold, the distance between the jet device and the air outlet is closer. This satisfies the requirement that a larger temperature difference results in a larger airflow from the air conditioner for rapid heating or cooling, and a smaller temperature difference results in a smaller airflow for normal heating or cooling, thus improving the overall stability of the air conditioner's airflow.

[0086] Optionally, the second set distance is 0.4 to 0.6 times the first set distance. In this way, when the distance between the jet device and the air outlet is the first set distance, the air volume of the air outlet is close to or equal to the maximum air volume of the air outlet. Therefore, setting the second set distance to 0.4 to 0.6 times the first set distance can control the air volume of the air outlet within a moderate range, and can more reasonably control the overall air output of the air conditioner.

[0087] Optionally, the second set distance is greater than or equal to one-twentieth of the air outlet width and less than or equal to one-eighteenth of the air outlet width. This makes the distance between the jet device and the air outlet related to the width of the air outlet itself, allowing for better control of the actual airflow from the air outlet in conjunction with its maximum ventilation volume. When the temperature difference is greater than 0 and less than or equal to the set threshold, it indicates that the difference between the indoor temperature and the set temperature is small. In this case, the air conditioner can operate smoothly in cooling or heating mode. Adjusting the distance between the jet device and the air outlet to between one-twentieth and one-eighteenth of the air outlet width ensures that the airflow from the air outlet is less than its maximum airflow, maintaining a reasonable airflow within a reasonable range. This maintains airflow stability during normal cooling or heating, improving the overall airflow stability of the air conditioner.

[0088] Optionally, the second set distance is one-twentieth of the air outlet width. Thus, when the temperature difference between the indoor temperature and the set temperature is greater than 0 and less than or equal to the set threshold, the position of the jet device is adjusted so that the distance between the jet device and the air outlet is equal to one-twentieth of the air outlet width. At this point, the jet device will obstruct the airflow, thereby controlling the airflow rate through the air outlet and keeping the airflow rate within a reasonable range. This maintains the stability of the airflow during normal cooling or heating, improving the overall stability of the air conditioner's air output.

[0089] Combination Figure 7 As shown, this embodiment of the present disclosure provides an apparatus for controlling an indoor unit of an air conditioner, including a first detection module 500 and a first control module 600. The first detection module 500 is configured to determine the position of a user; the first control module 500 is configured to control the rotation angle of the jet outlet according to the user's position.

[0090] The device for controlling the indoor unit of an air conditioner provided in this embodiment has a jetting device on one side of the air outlet. The jetting device has an adjustable jetting nozzle. By adjusting the angle of the jetting nozzle, the air outlet direction of the jet is changed, thereby changing the air outlet direction of the entire air outlet. The angle of the jetting nozzle is controlled according to the user's position, thereby controlling the air outlet direction. By changing the jetting angle, the air conditioner can have a variety of air outlet directions, meeting people's diverse needs for the air outlet direction of the indoor unit of the air conditioner.

[0091] Optionally, the first detection module 500 includes a location acquisition unit and an air outlet mode acquisition unit. The location acquisition unit is configured to determine the user's location; the air outlet mode acquisition unit is configured to determine the air outlet mode of the indoor unit of the air conditioner.

[0092] Optionally, the first control module 600 is further configured to control the rotation angle of the jet outlet based on the user's location and the air outlet mode of the indoor unit of the air conditioner. In this way, the air outlet demand can be determined based on the air outlet mode of the indoor unit of the air conditioner, and the rotation angle of the jet outlet can be better adjusted according to the user's location to meet different air outlet needs.

[0093] Optionally, the first detection module 500 further includes an operating mode acquisition unit. The operating mode acquisition unit is configured to determine the operating mode of the indoor unit of the air conditioner.

[0094] Optionally, the first control module 600 is further configured to control the rotation angle of the jet outlet based on the user's location, the air outlet mode of the indoor unit of the air conditioner, and the operating mode of the indoor unit. This allows for a more accurate determination of airflow demand based on the air outlet mode and operating mode of the indoor unit. By combining the airflow demand with the user's location, the rotation angle of the jet outlet can be better adjusted according to the user's position to meet different airflow needs.

[0095] Optionally, the device for controlling the indoor unit of the air conditioner further includes a second detection module 700 and a second control module 800.

[0096] The method for controlling the indoor unit of an air conditioner provided in this embodiment involves a jetting device on one side of the air outlet, with adjustable distance between the jetting device and the air outlet. The position of the jetting device is controlled based on the temperature difference between the indoor temperature and the set temperature. When the jetting device is close to the air outlet, it obstructs the airflow, reducing the air volume. When the jetting device is away from the air outlet, the airflow is unobstructed, increasing the air volume. The movable jetting device adjusts the overall air volume of the air conditioner. Simultaneously, the positional change between the jetting nozzle on the jetting device and the air outlet of the air conditioner alters the overall airflow driven by the jetting, enabling the air conditioner to have various airflow modes to meet diverse needs for airflow patterns.
