Description

Technical Field

[0001] This application relates to the field of refrigeration technology, for example, to a method, a device, and an air conditioner for controlling a floor-standing indoor unit of an air conditioner. Background Art

[0002] An air conditioner is a commonly used electrical appliance for improving the indoor environment of users. The magnitude of its temperature adjustment ability, the air supply mode, etc. are all related to the experience of users during the use of the air conditioner. Existing air conditioners and air supply devices generally adopt a design scheme of a single fan combined with a fixed flow guiding structure. Such devices use fixed flow guiding vanes or limit-swinging guide plates to achieve the basic air supply function. However, limited by the single power source and the unidirectional air flow channel design, the air supply dimension formed at the air outlet shows obvious singularity, and the air supply angle is usually limited within a plane range of 120° or less, resulting in uneven air supply volume distribution and low space coverage efficiency, and the personalized needs of users for multi-dimensional air supply cannot be fully met.

[0003] To break through the technical bottleneck of the single traditional air supply direction, related technologies have disclosed a multi-joint air guide plate system driven by a servo motor, which controls the swing amplitude and frequency of the guide plate through a preset program to achieve ±30° vertical air swing and 90° horizontal air sweep; at the same time, the fan speed is increased to more than 2000 rpm to increase the air supply volume. These technical means can all expand the air supply dimension within a limited range.

[0004] In the process of implementing the embodiments of the present disclosure, it is found that there are at least the following problems in the related technologies:

[0005] Although the related technologies can expand the air supply dimension to a certain extent, their core is still based on a single fan architecture, and the expansion of the air supply range can only be achieved by increasing the wind speed, which exacerbates the discomfort of direct air blowing. Therefore, how to provide a multi-dimensional air supply scheme that can effectively expand the air supply dimension and reduce the discomfort of direct air blowing to meet the personalized needs of users for multi-dimensional air supply has become an urgent technical problem to be solved.

[0006] It should be noted that the information disclosed in the above background art section is only used to enhance the understanding of the background of the present application, and therefore may include information that does not constitute the prior art known to those of ordinary skill in the art.

[0043] It should be noted that, without conflict, the embodiments and features in the embodiments of the present disclosure may be combined with each other.

[0044] An embodiment of the present disclosure provides a floor-mounted indoor air conditioner, which may also be referred to as a vertical indoor air conditioner. As shown in combination with Figures 1 to 7 shown:

[0045] Optionally, the indoor air conditioner includes a housing 1, a first blower 21, a second blower 22, a heat exchanger 3, and an air duct switching component 4. The housing 1 is provided with an air inlet 101, and a front air outlet 102 is provided at the upper part of the housing 1, and a side air outlet 103 is provided at the side part of the housing 1; the first blower 21 is communicated with the front air outlet 102 for blowing air forward; the second blower 22 is communicated with the side air outlet 103 for blowing air to the side; the heat exchanger 3 includes a first heat exchange part 31 and a second heat exchange part 32, and the air after heat exchange with the second heat exchange part 32 is sent out from the side air outlet 103 after passing through the second blower 22; the air duct switching component 4 is arranged between the first heat exchange part 31 and the first blower 21, and the air duct switching component 4 can be in a blocking state and a conducting state.

[0046] Among them, as Figure 4 shown, when the air duct switching component 4 is in the blocking state, the air duct switching component 4 blocks the first heat exchange part 31 and the first blower 21, and the air after heat exchange with the first heat exchange part 31 is sent out from the side air outlet 103; as Figure 5 shown, when the air duct switching component 4 is in the conducting state, the air after heat exchange with the first heat exchange part 31 is sent out from the front air outlet 102 after passing through the first blower 21.

[0047] Optionally, the housing 1 includes a front housing part 11, a rear housing part, and a side housing part 12, and the front housing part 11 is arranged opposite to the rear housing part. Among them, the air inlet 101 is opened on the rear housing part, and an air inlet grille is arranged at the air inlet 101; the front air outlet 102 is opened at the upper part of the front housing part 11, the side air outlet 103 includes a first side air outlet and a second side air outlet, the side air outlet 103 can be opened on the side housing part 12, and the side air outlet 103 can also be opened on the side part of the front housing part 11.

[0048] Optionally, the front air outlet 102 is arranged above the side air outlet 103. Optionally, the front air outlet 102 can be circular, square, or other regular or irregular shapes; the side air outlet 103 is strip-shaped.

[0049] Optionally, the first blower 21 includes a centrifugal blower, an axial flow blower, a cross-flow blower, etc.; the second blower 22 includes a cross-flow blower, a centrifugal blower, an axial flow blower, etc. For example, the first blower 21 is a centrifugal blower, the second blower 22 is a cross-flow blower, and the centrifugal blower is arranged above the cross-flow blower.

[0050] The indoor air conditioner provided by the embodiments of the present disclosure further includes an air duct switching component 4. The air duct switching component 4 is disposed between the first heat exchange part 31 of the heat exchanger 3 and the first blower 21. When only the side air outlet 103 needs to supply air, at this time, the first blower 21 for supplying air to the front air outlet 102 is in the closed state, and the second blower 22 for supplying air to the side air outlet 103 is in the open state. The air duct switching component 4 can be controlled to be in a blocking state that blocks the first heat exchange part 31 and the first blower 21, and the air duct switching component 4 forms an air duct between the first heat exchange part 31 and the second blower 22. At this time, the air-conditioning air with heat or cold generated by the first heat exchange part 31 can be sent out from the side air outlet 103 through the second blower 22.

[0051] It can be seen that for the indoor air conditioner provided by the embodiments of the present disclosure, when only the side air outlet 103 needs to supply air, with the first blower 21 turned off, the heat or cold generated by the first heat exchange part 31 can be sent out from the side air outlet 103 through the second blower 22, improving the heat exchange efficiency of the heat exchanger 3. At the same time, problems such as condensation caused by the inability of the first heat exchange part 31 to discharge cold air in time are avoided.

[0052] As Figure 5 shown, when the user needs to supply air from both the front air outlet 102 and the side air outlet 103 at the same time, the air duct switching component 4 can be controlled to be in the conducting state. At this time, the air duct between the first heat exchange part 31 of the heat exchanger 3 and the first blower 21 is conducted, and the air-conditioning air with heat or cold generated by the first heat exchange part 31 can be sent out from the front air outlet 102 after passing through the first blower 21.

[0053] As Figure 5 shown, optionally, in the vertical direction, the second heat exchange part 32 of the heat exchanger 3 is disposed opposite to the second blower 22, that is, the second heat exchange part 32 and the second blower 22 are generally disposed at the same height; optionally, the first blower 21 is disposed above the first heat exchange part 31.

[0054] As Figure 5 shown, optionally, when the air duct switching component 4 is controlled to be in the conducting state, the air duct switching component 4 forms an air duct partition, and the air duct partition can be generally in the shape of a horizontal flat plate. Moreover, the air duct switching component 4 separates the air-conditioning air generated by the first heat exchange part 31 and the second heat exchange part 32 of the heat exchanger 3, so that the air-conditioning air generated by the first heat exchange part 31 is sent out from the front air outlet 102 after passing through the first blower 21, and the air-conditioning air generated by the second heat exchange part 32 is sent out from the side air outlet 103 after passing through the second blower 22.

[0055] Optionally, the first heat exchange part 31 and the second heat exchange part 32 of the heat exchanger 3 are integrally formed, and the refrigerant pipelines between the first heat exchange part 31 and the second heat exchange part 32 are interconnected.

[0056] Optionally, the air duct switching component 4 includes a movable air duct portion and a driving assembly. The driving assembly is used to drive the movable air duct portion to rotate or move. When the driving assembly drives the movable air duct portion to rotate to the blocking state, the air duct switching component 4 blocks between the first heat exchange portion 31 and the first air inlet 212 of the air wheel.

[0057] Optionally, the driving assembly may include a driving motor, and the movable air duct portion may be a plate-shaped air duct plate. The movable air duct portion can be rotated under the drive of the driving assembly so that the movable air duct plate portion rotates to the blocking state or the conducting state.

[0058] When the movable air duct plate portion rotates to the blocking state, the air duct switching component 4 blocks between the first heat exchange portion 31 and the first air blower 21, and at the same time, an air duct between the first heat exchange portion 31 and the second air blower 22 is formed. In this way, when only the side air outlet 103 needs to supply air, the air-conditioning air generated by the first heat exchange portion 31 can be sent out from the side air outlet 103 through the second air blower 22.

[0059] Optionally, the movable air duct portion includes a first rotating air duct plate 41. When the first rotating air duct plate 41 is in the conducting state, the first rotating air duct plate 41 is in a vertical state; when the first rotating air duct plate 41 is in the blocking state, the first rotating air duct plate 41 is in an inclined state.

[0060] Optionally, the rotation angle formed when the first rotating air duct plate 41 rotates from the conducting state to the blocking state is greater than 95° and less than or equal to 150°.

[0061] Optionally, the movable air duct portion further includes a second rotating air duct plate 42. When the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 so that the first rotating air duct plate 41 and the second rotating air duct plate 42 jointly block the first heat exchange portion 31 and the first air blower 21.

[0062] When the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 is in an inclined state, and the second rotating air duct plate 42 is also in an inclined state. The first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 so that the first rotating air duct plate 41 and the second rotating air duct plate 42 jointly block the first heat exchange portion 31 and the first air blower 21.

[0063] The first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 to form an overlapping air duct, so that the air-conditioning air of the first heat exchange portion 31 of the heat exchanger 3 is sent out from the side air outlet 103 through the second air blower 22.

[0064] Optionally, when the air duct switching component 4 is in the blocking state, the second rotating air duct plate 42 overlaps with the first rotating air duct plate 41. The overlapping position of the first rotating air duct plate 41 and the second rotating air duct plate 42 is located on the inner wall of the first rotating air duct plate 41, rather than at the second rotating end 412 of the first rotating air duct plate 41. In this way, when the air duct switching component 4 is in the blocking state, a part of the remaining length of the first rotating air duct plate 41 is available. This part of the remaining length can be used to adjust the overlapping angle formed by the first rotating air duct plate 41 and the second rotating air duct plate 42.

[0065] Optionally, the overlapping angle A formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 at the overlapping point is greater than 135° and less than 180°.

[0066] Optionally, the overlapping angle A formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 can be adjusted according to the rotation speed of the second blower 22. For example, when the rotation speed of the second blower 22 is the first rotation speed, the first rotating air duct plate 41 and the second rotating air duct plate 42 form a first overlapping angle; when the rotation speed of the second blower 22 is the second rotation speed, the first rotating air duct plate 41 and the second rotating air duct plate 42 form a second overlapping angle, where the first rotation speed is greater than the second rotation speed, and the first overlapping angle is less than the second overlapping angle.

[0067] When the second overlapping angle is less than the first overlapping angle, the volume of the air duct formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 at the second overlapping angle is greater than the volume of the air duct formed at the first overlapping angle. In this way, when the second blower operates at the first rotation speed with a higher rotation speed, the first rotating air duct plate 41 and the second rotating air duct plate 42 form an air duct with a larger volume, thereby improving the delivery effect of the air-conditioning air of the first heat exchange part 31 from the side air outlet 103 after passing through the second blower 22.

[0068] Optionally, by adjusting the angle between the first rotating air duct plate 41 and the horizontal direction, and adjusting the angle between the second rotating air duct plate 42 and the horizontal direction, the first rotating air duct plate 41 and the second rotating air duct plate 42 can form a first overlapping angle, or the first rotating air duct plate 41 and the second rotating air duct plate 42 can form a second overlapping angle.

[0069] The third rotating end 421 of the second rotating air duct plate 42 forms a first preset connection line with the first heat exchange end. When the air duct switching component 4 is in the blocking state, the overlapping point formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 is located above the first preset connection line, as shown in Figure 7 A shown in the figure. In this way, the volume of the overlapping air duct formed after the first rotating air duct plate 41 and the second rotating air duct plate 42 overlap is increased, and the air delivery effect of the air-conditioning air of the first heat exchange part 31 from the side air outlet 103 is improved.

[0070] Optionally, the vertical distance from the overlapping point formed by the first rotating air duct plate 41 and the second rotating air duct plate 42 to the first preset connection line is greater than 0 and less than or equal to 10 mm. In this way, when the air duct switching component 4 is in the blocking state, the air guiding effect of the first rotating air duct plate 41 and the second rotating air duct plate 42 is improved.

[0071] Optionally, the second rotating air duct plate 42 is in the shape of a flat plate.

[0072] Optionally, the second rotating air duct plate 42 is in the shape of an inward concave arc. It can be understood that when the second rotating air duct plate 42 is in the blocking state or the conducting state, the inward concave second rotating air duct plate 42 protrudes towards the second blower 22. In this way, when the air duct switching component 4 forms a blocking state, the inward concave second rotating air duct plate 42 is conducive to forming an extension plate of the air duct of the first rotating air duct plate 41 and breaks the climbing effect of the wind, so that the wind smoothly passes through the second blower 22 and is sent out from the side air outlet 103; in addition, when the air duct switching component 4 is in the conducting state, the inward concave second rotating air duct plate 42 will not block the air-conditioning wind of the first heat exchange part 31, improving the air supply effect of the first blower 21.

[0073] Optionally, the air duct switching component 4 further includes a fixed air duct plate 43. The fixed air duct plate 43 includes a first fixed end 431 and a second fixed end 432. Among them, the first fixed end 431 is arranged at the third rotating end 421 of the second rotating air duct plate 42. When the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41, the second rotating air duct plate 42 and the fixed air duct plate 43 jointly block the first heat exchange part 31 and the first blower 21; when the air duct switching component 4 is in the conducting state, the second rotating air duct plate 42 and the fixed air duct plate 43 form an air duct partition, and the air after heat exchange with the first heat exchange part 31 passes through the first blower 21 and is sent out from the front air outlet 102.

[0074] Optionally, the fixed air duct plate 43 is a fixed flat plate structure and does not need to rotate. The fixed air duct plate 43 can be used as an extended air duct plate of the second rotating air duct plate 42. Optionally, the fixed air duct plate 43 is arranged horizontally.

[0075] Optionally, when the air duct switching component 4 is in the conducting state, the second rotating air duct plate 42 is in the shape of a flat plate and is arranged horizontally. The second rotating air duct plate 42 and the fixed air duct plate 43 form an air duct partition on the same horizontal line.

[0076] Optionally, when the air duct switching component 4 is in the blocking state, the air duct switching component 4 at least includes a part of a non-horizontal air duct plate section 401.

[0077] When the air duct switching component 4 is in the blocking state, the air duct switching component 4 at least includes a part of the air duct plate section in a non-horizontal state. It can be understood that the non-horizontal air duct plate section 401 can be an inclined air duct plate, or composed of a plurality of inclined air duct plate sections together. For example, the first rotating air duct plate 41 and the second rotating air duct plate 42 in the inclined state are the non-horizontal air duct plate sections 401 of the air duct switching component 4.

[0078] Optionally, when the air duct switching component 4 is in the blocking state, the fixed air duct plate 43 constitutes a horizontal air duct plate section.

[0079] Optionally, the air duct switching component 4 includes a movable air duct part and a driving assembly. The movable air duct part includes a first rotating air duct plate 41 and a second rotating air duct plate 42; the driving assembly includes a first driving motor and a second driving motor, and the first driving motor is used to drive the first rotating air duct plate 41 to rotate, and the second driving motor is used to drive the second rotating air duct plate 42 to rotate. Wherein, when the air duct switching component 4 is in the blocking state, the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 to block the first heat exchange part 31 and the first fan 21.

[0080] In the embodiment of the present disclosure, the first driving motor and the second driving motor are respectively used to drive the first rotating air duct plate 41 and the second rotating air duct plate 42 to rotate. Optionally, the first driving motor can be installed on the inner wall of the housing 1, and the second driving motor can also be installed on the inner wall of the housing 1.

[0081] When the inner wall of the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42, the second driving motor can be controlled to drive the second rotating air duct plate 42 to rotate to the overlapping position first, and then the first driving motor can be controlled to drive the first rotating air duct plate 41 to overlap with the second rotating air duct plate 42.

[0082] Optionally, when the air duct switching component 4 is in the blocking state, the first driving motor drives the first rotating air duct plate 41 to rotate to an inclined state, the second driving motor drives the second rotating air duct plate 42 to rotate to an inclined state, and the first rotating air duct plate 41 overlaps with the second rotating air duct plate 42 to form a non-horizontal air duct plate section 401.

[0083] The air conditioner indoor unit provided by the embodiment of the present disclosure is provided with a front air outlet 102 and a side air outlet 103 located below the front air outlet 102 at the same time. Optionally, the front air outlet 102 can be applied to operation modes such as long-distance air supply, rapid cooling or rapid heating; when the air outlet temperature of the air conditioner indoor unit is not much different from the set temperature, only the side air outlet 103 can be used for air supply.

[0084] When only the side air outlet 103 needs to supply air, the duct switching component 4 can be controlled to rotate to the blocking state, so that the air-conditioning air of the first heat exchange part 31 of the heat exchanger 3 is sent out from the side air outlet 103 after passing through the second fan 22, which improves the heat exchange efficiency of the heat exchanger 3. At the same time, problems such as condensation caused by cold accumulation in the first heat exchange part 31 are avoided.

[0085] Combined with Figure 8 As shown, an embodiment of the present disclosure provides a method for controlling a floor-standing air conditioner indoor unit, including:

[0086] S81. When the air conditioner is started, the air conditioner obtains the set temperature of the air conditioner and the temperature of the room where the air conditioner is located.

[0087] S82. The air conditioner controls the duct switching component according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the duct switching component is in the blocking state or the conducting state.

[0088] Wherein, when the duct switching component is in the conducting state, the air after heat exchange with the first heat exchange part is sent out from the front air outlet after passing through the first fan; when the duct switching component is in the blocking state, the duct switching component blocks the first heat exchange part and the first fan, and the air after heat exchange with the first heat exchange part is sent out from the side air outlet.

[0089] In this solution, when the air conditioner is started, the air conditioner can obtain the set temperature of the air conditioner and the temperature of the room where the air conditioner is located. Specifically, the set temperature is usually input by the user through a remote control or the control panel of the air conditioner. There are various designs for obtaining the room temperature. In one example, in order to ensure the accuracy and reliability of the temperature information, the air conditioner can obtain the room temperature through a built-in temperature sensor. The sensor is installed at the air inlet of the air conditioner and can monitor the air temperature entering the air conditioner in real time, thereby indirectly reflecting the temperature situation in the room. In another example, the air conditioner can also be equipped with an external temperature sensor, and the external temperature sensor is connected to the air conditioner wirelessly or by wire. The external sensor can be placed at different positions in the room to measure the actual temperature in the room more accurately and avoid affecting the measurement result due to local temperature changes near the air conditioner. In an optimized solution, in a smart home environment, the air conditioner can directly obtain the room temperature information from other smart devices through integration with the smart home system. These smart devices are distributed in various corners of the room and can provide more comprehensive and accurate temperature data, providing a more reliable basis for the intelligent control of the air conditioner. Optionally, the user can also manually input the room temperature according to his actual feeling. Although this method is not as accurate as automatic detection, it can be used as a supplementary means when there is no sensor or the sensor fails to ensure that the air conditioner can still operate according to the user's subjective needs.

[0090] Further, after the air conditioner obtains the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, the air duct switching component is controlled according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state. In one example, when the difference between the set temperature of the air conditioner and the room temperature is large, it indicates that the air conditioner needs to quickly adjust the room temperature to reach the set value. At this time, the air duct switching component is controlled to be in a conducting state, so that the air after heat exchange with the first heat exchange part is sent out from the front air outlet after passing through the first fan. The front air outlet usually has a relatively long air supply distance, which can quickly send cold air or warm air to all corners of the room and accelerate the adjustment of the room temperature. When the difference between the set temperature and the room temperature is small, it indicates that the room temperature is already close to the set value. At this time, the air duct switching component is controlled to be in a blocked state, blocking the first heat exchange part and the first fan, so that the air after heat exchange with the first heat exchange part is sent out from the side air outlet, in order to provide a more comfortable air supply experience for the user and reduce the discomfort caused by the direct blowing of the air flow at the same time.

[0091] With this solution, by using the air duct switching component, according to the difference between the set temperature and the room temperature, the air duct state is flexibly switched to realize air supply from the front air outlet or the side air outlet. This not only enriches the air supply dimension, expands the space coverage range, but also can adjust the air supply direction according to the demand, avoiding the direct blowing of the air flow to the user. Therefore, while effectively expanding the air supply dimension, it significantly reduces the discomfort caused by the direct blowing of the air flow, meets the personalized needs of the user for multi-dimensional air supply, and improves the use experience and space adjustment efficiency of the air conditioner.

[0092] Optionally, in S82, the air conditioner controls the air duct switching component according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state, including:

[0093] When the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located is greater than the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the conducting state.

[0094] When the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located is less than or equal to the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the blocked state.

[0095] In this solution, during the operation of the air conditioner, the set temperature of the air conditioner and the temperature of the room where it is located can be monitored in real time, and the difference between the two can be calculated. It should be noted that if the difference is less than zero, the absolute value of the difference needs to be determined and compared with the temperature difference threshold. Specifically, when the difference is greater than the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the conducting state. At this time, the air duct between the first heat exchange part and the first fan is unobstructed, and the air after heat exchange is sent out from the front air outlet through the first fan. At the same time, the second fan also keeps running, so that the air after heat exchange through the second heat exchange part is sent out from the side air outlet, realizing simultaneous air supply from the front air outlet and the side air outlet. This simultaneous air supply method can quickly adjust the room temperature when the room temperature differs greatly from the set temperature, improving the cooling or heating efficiency of the air conditioner. In addition, when the difference between the set temperature of the air conditioner and the room temperature is less than or equal to the temperature difference threshold, the air conditioner controls the air duct switching component to switch to the blocking state. At this time, the air duct switching component blocks the first heat exchange part and the first fan, so that the air after heat exchange through the first heat exchange part cannot enter the first fan, but is directly sent out through the side air outlet. This method of only supplying air through the side air outlet is suitable when the room temperature is close to the set temperature, which can provide a softer and more uniform air supply experience for users, reduce the discomfort caused by direct air blowing, and maintain the stability of the room temperature.

[0096] With this solution, not only the performance of the air conditioner is optimized, but also the user experience is improved, enabling it to better adapt to different usage scenarios and requirements.

[0097] In this solution, the temperature difference threshold can be set in advance. As an example, the temperature difference threshold can be 2°C.

[0098] Optionally, the temperature difference threshold is dynamically adjusted according to the following information:

[0099] The current time information; or,

[0100] The current outdoor environmental parameter information; or,

[0101] The current indoor environmental parameter information; or,

[0102] The current season information; or,

[0103] The current geographical location information.

[0104] In one example, the temperature difference threshold can be adjusted according to the current time information. For example, at night or in the sleep mode set by the user, the temperature difference threshold can be appropriately reduced so that the air conditioner can switch to a softer air supply mode at a smaller temperature difference, reducing the interference of the air supply at night to the user and providing a more comfortable sleep environment. During the day or when the user is more active, the temperature difference threshold can be appropriately increased so that the air conditioner can more actively adjust the indoor temperature to meet the higher temperature requirements of the user during activities.

[0105] In one example, the temperature difference threshold can also be adjusted according to the current outdoor environmental parameter information. For example, when the outdoor temperature is relatively high or low, the temperature difference threshold can be appropriately increased so that the air conditioner can more actively adjust the indoor temperature to cope with the large indoor-outdoor temperature difference. In addition, if the outdoor humidity is relatively high, the temperature difference threshold can also be appropriately adjusted to ensure that the air conditioner reaches the best balance between dehumidification and refrigeration or heating, improving the comfort of the user.

[0106] In one example, the temperature difference threshold can be dynamically adjusted according to the current indoor environmental parameter information. For example, if the indoor humidity is relatively high, the temperature difference threshold can be appropriately reduced so that the air conditioner can switch to the ventilation mode more frequently, reducing the indoor humidity and improving the indoor air quality. If the indoor air quality is poor, the temperature difference threshold can also be appropriately adjusted so that the air conditioner can more effectively circulate and purify the air.

[0107] In one example, the temperature difference threshold can also be adjusted according to the current season information. In summer or winter, due to the large indoor-outdoor temperature difference, the temperature difference threshold can be appropriately increased so that the air conditioner can more effectively adjust the indoor temperature. In spring and autumn, the temperature difference threshold can be appropriately reduced to achieve a more energy-saving operation mode and reduce unnecessary energy consumption.

[0108] In one example, the temperature difference threshold can be adjusted according to the current geographical location information. For example, in locations close to windows or doors, since these areas are more easily affected by the external temperature, the temperature difference threshold can be appropriately increased to ensure that the temperature in these areas can also be effectively adjusted. In addition, under the climatic conditions of different geographical locations, the temperature difference threshold can also be optimized and adjusted according to the local climatic characteristics to meet different environmental requirements.

[0109] With this solution, by introducing a mechanism for dynamically adjusting the temperature difference threshold, the air conditioner can flexibly adjust the air supply mode according to various information such as the current time, indoor and outdoor environmental parameters, season, and geographical location, achieving more accurate and intelligent temperature regulation and air supply control. This intelligent control method can not only meet the personalized needs of users in different scenarios, but also effectively reduce energy consumption, providing a more comfortable and energy-saving indoor environment for users.

[0110] CombinedFigure 9 As shown, optionally, the air duct switching component includes a movable air duct part, and the movable air duct part includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in the blocking state, the first rotating air duct plate overlaps with the second rotating air duct plate, so that the first rotating air duct plate and the second rotating air duct plate jointly block the first heat exchange part and the first fan. The method further includes:

[0111] S91, the air conditioner obtains the rotation speed of the second fan.

[0112] S92, the air conditioner adjusts the overlapping angle between the first rotating air duct plate and the second rotating air duct plate according to the rotation speed of the second fan.

[0113] In this solution, when the rotation speed of the second fan is the first rotation speed, the first rotating air duct plate and the second rotating air duct plate form a first overlapping angle. When the rotation speed of the second fan is the second rotation speed, the first rotating air duct plate and the second rotating air duct plate form a second overlapping angle, where the first rotation speed is greater than the second rotation speed, and the first overlapping angle is less than the second overlapping angle.

[0114] Specifically, when the second overlapping angle is less than the first overlapping angle, the volume of the air duct formed by the first rotating air duct plate and the second rotating air duct plate at the second overlapping angle is greater than the volume of the air duct formed at the first overlapping angle. In this way, when the second fan operates at the first rotation speed with a relatively high speed, the first rotating air duct plate and the second rotating air duct plate form an air duct with a larger volume, thereby improving the delivery effect of the air-conditioning air from the first heat exchange part through the second fan and out of the side air outlet.

[0115] Optionally, by adjusting the angle between the first rotating air duct plate and the horizontal direction, and adjusting the angle between the second rotating air duct plate and the horizontal direction, the first rotating air duct plate and the second rotating air duct plate can form a first overlapping angle, or the first rotating air duct plate and the second rotating air duct plate can form a second overlapping angle.

[0116] Optionally, the air duct switching component includes a movable air duct part, and the movable air duct part includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in the blocking state, the first rotating air duct plate overlaps with the second rotating air duct plate, so that the first rotating air duct plate and the second rotating air duct plate jointly block the first heat exchange part and the first fan. The method further includes:

[0117] The air conditioner determines the user's air supply intention, and the air supply intention includes mild cold air supply and strong cold air supply.

[0118] When the user's air supply intention is mild cold air supply, the air conditioner increases the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0119] When the user's air supply intention is strong cold air supply, the air conditioner reduces the overlapping angle between the first rotating air duct plate and the second rotating air duct plate.

[0120] In this solution, the movable air duct part of the air duct switching component includes a first rotating air duct plate and a second rotating air duct plate. When the air duct switching component is in the blocking state, the first rotating air duct plate overlaps with the second rotating air duct plate, jointly blocking the first heat exchange part and the first fan, so that the air after heat exchange through the first heat exchange part can only be sent out from the side air outlet. This design not only optimizes the air supply direction but also improves the heat exchange efficiency. To further meet the personalized needs of users, this method also includes the step of adjusting the overlapping angle between the first rotating air duct plate and the second rotating air duct plate according to the user's air supply intention.

[0121] When the air conditioner determines the user's air supply intention, it will make corresponding air duct adjustments according to the mode selected by the user. If the user selects the mild cold air supply mode, the air conditioner will increase the overlapping angle between the first rotating air duct plate and the second rotating air duct plate through the internal driving mechanism. This adjustment makes the air duct volume formed between the first rotating air duct plate and the second rotating air duct plate smaller. Understandably, due to the reduction of the air duct volume, the flow path of the air in the air duct becomes narrower, and the air speed and air volume will both decrease accordingly. After the air conditioner air cooled by the first heat exchange part passes through the second fan and is sent out from the side air outlet, the reduction of the air volume and air speed makes the intensity of the blown cold air weaken, thus realizing the gentle breeze effect. This gentle breeze effect can provide users with a more gentle and comfortable cold air experience and is suitable for use in scenarios where the temperature is appropriate but a slight temperature reduction is needed.

[0122] On the contrary, when the user selects the strong cold air supply mode, the air conditioner will reduce the overlapping angle between the first rotating air duct plate and the second rotating air duct plate. At this time, the air duct volume formed between the first rotating air duct plate and the second rotating air duct plate increases. The increase in the air duct volume makes the flow path of the air in the air duct wider, and the air speed and air volume will both increase accordingly. After the air conditioner air cooled by the first heat exchange part passes through the second fan and is sent out from the side air outlet, the increase in the air volume and air speed makes the intensity of the blown cold air increase, thus realizing the strong cold effect. This strong cold effect can quickly reduce the indoor temperature and is suitable for use in hot weather or scenarios where rapid temperature reduction is needed.

[0123] In the process of implementing these two air supply modes, the control system of the air conditioner will accurately control the rotation angle of the air duct plate according to the user's selection. The control system will monitor the angle change of the air duct plate in real time and make fine adjustments based on the feedback information to ensure that the air duct adjustment conforms to the user's air supply intention. At the same time, the control system will also coordinate the adjustment of the fan speed according to the angle change of the air duct plate to further optimize the air supply effect. For example, in the mild cooling air supply mode, the fan speed may be appropriately reduced to further reduce the air volume and wind speed; while in the strong cooling air supply mode, the fan speed may be appropriately increased to enhance the air supply effect.

[0124] In addition, the air conditioner can also allow the user to intuitively select the mild cooling air supply or strong cooling air supply mode through the user interface and display the current air supply status in real time. If the user is not satisfied with the air supply effect, they can make adjustments through the interface, and the control system will re-adjust the angle of the air duct plate and the fan speed according to the user's feedback to ensure that the user obtains a satisfactory air supply experience.

[0125] Through this design, the air conditioner can flexibly adjust the overlapping angle of the air duct plate according to the user's air supply intention, thereby realizing the switching between mild cooling air supply and strong cooling air supply. This solution can not only accurately meet the user's needs for different air supply intensities, but also improve the operating efficiency and comfort of the air conditioner. In the mild cooling air supply mode, by reducing the air duct volume to reduce the air volume and wind speed, it avoids the discomfort caused by excessive cooling; in the strong cooling air supply mode, by increasing the air duct volume to increase the air volume and wind speed, it quickly reduces the indoor temperature and improves the refrigeration effect. At the same time, this adjustment method can also reduce the energy consumption of the air conditioning system because the optimization of the air duct can reduce the operating load of the fan, thereby achieving the effect of energy saving.

[0126] In an optimized solution, the air conditioner can predict the user's preferences and habits by recording the user's historical usage data. For example, the system can record the air supply mode selected by the user at different time periods (such as during the day, at night, on weekends, etc.) and the corresponding overlapping angle of the air duct plate. By analyzing this historical data, the air conditioner can automatically adjust the overlapping angle of the air duct plate to meet the user's routine needs.

[0127] In an optimized solution, the air conditioner can also use a preset model to dynamically adjust the overlapping angle of the air duct plate. These models can predict the optimal air supply mode based on various factors, such as indoor and outdoor temperature, humidity, season, geographical location, etc. For example, during high-temperature periods in summer, the model may suggest reducing the overlapping angle to provide strong cold air supply; while in spring and autumn or when the indoor temperature is relatively low, the model may suggest increasing the overlapping angle to provide mild cold air supply. In addition, the model can also combine the indoor humidity situation. If the indoor humidity is high, it may suggest appropriately reducing the overlapping angle to enhance the dehumidification effect. In this way, the air conditioner can automatically adjust the overlapping angle of the air duct plate according to the changes in environmental conditions, so as to provide the best air supply effect in different usage scenarios.

[0128] Optionally, the method further includes:

[0129] The air conditioner determines the user's air supply intention, and the air supply intention includes normal-temperature air supply, mild cold air supply, and strong cold air supply.

[0130] When the user's air supply intention is normal-temperature air supply, the air conditioner controls the air duct switching component to be in a blocked state and starts the first fan to provide normal-temperature gentle wind for the user through the front air outlet.

[0131] When the user's air supply intention is mild cold air supply, the air conditioner controls the air duct switching component to be in a blocked state and starts the first fan and the second fan, so that the front air outlet outputs normal-temperature gentle wind and the side air outlet outputs cold air, so as to provide mild wind for the user through the mixing of the two.

[0132] When the user's air supply intention is strong cold air supply, the air conditioner controls the air duct switching component to switch to a conducting state and starts the first fan and the second fan, so that the front air outlet and the side air outlet output cold air synchronously to achieve rapid cooling.

[0133] In this solution, the user's air supply intention is subdivided into three modes: normal-temperature air supply, mild cold air supply, and strong cold air supply. The air conditioner can flexibly adjust the state of the air duct switching component and the operation mode of the fan according to different air supply intentions to meet the personalized needs of users in different scenarios. Specifically, when the user's air supply intention is normal-temperature air supply, the air conditioner controls the air duct switching component to be in a blocked state. At this time, the air duct between the first heat exchange part and the first fan is blocked, indicating that the air after being heat-exchanged by the first heat exchange part cannot directly enter the first fan. Therefore, the air conveyed by the first fan will not pass through the first heat exchange part for further temperature adjustment, so as to provide gentle wind close to normal temperature for the user.

[0134] When the user's air supply intention is to supply slightly cold air, the air conditioner also controls the air duct switching component to be in a blocked state. However, at this time, the first fan and the second fan will be started simultaneously. The first fan outputs normal-temperature gentle air from the front air outlet, while the second fan outputs cold air from the side air outlet. Through the mixing of the air from the front air outlet and the side air outlet, a slightly cold air supply effect is provided for the user. This mode is suitable for use in scenarios where the user needs to slightly cool down but does not want to be blown by strong cold air, such as when the indoor temperature is relatively high but the user is sensitive to cold air.

[0135] When the user's air supply intention is to supply strong cold air, the air conditioner controls the air duct switching component to switch to a conducting state. At this time, the air duct between the first heat exchange part and the first fan is unobstructed, and the first fan and the second fan operate simultaneously, so that the front air outlet and the side air outlet output cold air synchronously. This mode can quickly reduce the room temperature and is suitable for use in hot weather or when the user needs to quickly cool down, such as during high-temperature periods in summer or when the user first enters the room and needs to quickly cool down.

[0136] With this solution, the user can select different air supply modes according to their comfort preferences, and the air conditioner realizes the corresponding air supply effect through intelligent control. This intelligent control method not only improves the user's usage experience but also further enhances the energy efficiency and heat exchange efficiency of the air conditioner, enabling it to perform excellently in various complex usage environments. By dynamically adjusting the air supply mode, the air conditioner can more accurately control the air supply volume and air speed, so that while quickly cooling or heating, it can also provide a more comfortable and uniform air supply experience for the user, significantly improving the overall performance of the air conditioner and the user's satisfaction.

[0137] Optionally, the air conditioner determines the user's air supply intention, including:

[0138] The air conditioner obtains the key value information, environmental parameter data, human body state data, and historical habit data input by the user.

[0139] The air conditioner determines the user's air supply intention based on the key value information, environmental parameter data, human body state data, and historical habit data input by the user.

[0140] In this solution, the air conditioner determines the user's air supply intention by comprehensively analyzing the key value information, environmental parameter data, human body state data, and historical habit data input by the user. Specifically, the air conditioner can obtain the key value information input by the user through the remote control or the air conditioner panel. The key value information can include the set temperature, wind speed gear, air supply mode, etc. For example, if the user sets the temperature to 24°C, selects "low" for the wind speed, and selects the "cooling" mode, the air conditioner will initially judge that the user may need slightly cold air supply. At the same time, the air conditioner obtains environmental parameter data through built-in or external sensors, such as indoor temperature, humidity, and air quality. If the indoor temperature is 28°C and the humidity is 60%, the air conditioner will further judge that the user may need a stronger cooling effect by combining these data. In addition, the air conditioner can also obtain human body state data through smart wearable devices or body sensors, such as the user's body temperature and activity status. If the user's body temperature is 37°C and is in an active state, the air conditioner may adjust its judgment and consider that the user needs stronger cold air to cool down. Finally, the air conditioner will refer to the historical habit data to understand the user's preferences under similar conditions. For example, if the historical data shows that the user usually selects slightly cold air supply at night, the air conditioner will automatically adjust to this mode at night. By integrating these data, the air conditioner can more accurately determine the user's air supply intention and achieve personalized and intelligent air supply control.

[0141] As an example, the air conditioner can determine the user's air supply intention through the weighted analysis method. Specifically, the air conditioner assigns different weights to the key value information, environmental parameter data, human body state data, and historical habit data input by the user. For example, the weight of the key value information is relatively high because this is the way for the user to directly express their needs; the weight of the environmental parameter data is the second, which is used to correct and supplement the key value information; the weight of the human body state data is the third, which is used to further refine the needs; the weight of the historical habit data is the lowest, but it can be used as a long-term reference. Through weighted calculation, a comprehensive judgment result is obtained, thereby determining the air supply intention.

[0142] As an example, the air conditioner can determine the user's air supply intention through the hierarchical decision-making method. Specifically, the air conditioner makes a preliminary judgment based on the key value information input by the user to determine a basic air supply mode. Then, it adjusts the preliminary judgment by combining the environmental parameter data. For example, it fine-tunes the air supply intensity or temperature setting according to the indoor temperature and humidity. Next, it further optimizes the air supply mode by referring to the human body state data, such as adjusting the wind speed or direction according to the user's body temperature and activity status. Finally, it fine-tunes the final result by combining the historical habit data to ensure that the air supply mode conforms to the user's long-term preferences.

[0143] As an example, the air conditioner can determine the user's air supply intention through data fusion and machine learning algorithms. Specifically, the air conditioner fuses the key value information input by the user, environmental parameter data, human body state data, and historical habit data to form a comprehensive data set. Through machine learning algorithms (such as decision trees, neural networks, etc.), these data are trained and analyzed to establish a prediction model. When new data is input, the model can automatically identify and predict the user's air supply intention, thereby realizing intelligent air supply control.

[0144] With this solution, by comprehensively analyzing the key value information input by the user, environmental parameter data, human body state data, and historical habit data to determine the air supply intention, more intelligent and personalized air supply control can be achieved. This multi-dimensional data analysis method not only improves the intelligent level of the air conditioner but also significantly enhances the user experience. The air conditioner can automatically adjust the air supply mode according to the actual needs and environmental conditions of the user, providing the most comfortable and energy-saving air supply effect for the user. This intelligent control method reduces the frequency of manual operation by the user, improves the convenience of use, and at the same time provides data support for the efficient operation of the air conditioner.

[0145] The embodiment of the present disclosure provides a device for controlling a floor-standing air conditioner indoor unit, including an acquisition module and a control module. The acquisition module is configured to acquire the set temperature of the air conditioner and the temperature of the room where the air conditioner is located when the air conditioner is started; the control module is configured to control the air duct switching component according to the difference between the set temperature of the air conditioner and the temperature of the room where the air conditioner is located, so that the air duct switching component is in a blocked state or a conducting state. Wherein, when the air duct switching component is in the conducting state, the air after heat exchange with the first heat exchange part is sent out from the front air outlet after passing through the first fan; when the air duct switching component is in the blocked state, the air duct switching component blocks the first heat exchange part and the first fan, and the air after heat exchange with the first heat exchange part is sent out from the side air outlet.

[0146] By using the device for controlling a floor-standing air conditioner indoor unit provided by the embodiment of the present disclosure, the air duct state can be flexibly switched according to the difference between the set temperature and the room temperature by using the air duct switching component, so as to realize air supply from the front air outlet or the side air outlet. This not only enriches the air supply dimension, expands the space coverage range, but also can adjust the air supply direction according to the demand to avoid the air flow directly blowing on the user. Thus, while effectively expanding the air supply dimension, it significantly reduces the discomfort caused by the direct air flow, meets the user's personalized needs for multi-dimensional air supply, and improves the user experience and space adjustment efficiency of the air conditioner.

The communication interface 1002 can be used for information transmission.
