Technical Field

[0001] This invention relates to the field of air conditioning technology, and more particularly to a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. Background Technology

[0002] With the development of economy and technology, the application of air conditioners has become more and more widespread. At present, many air conditioners have a cold air prevention function. During the cold air prevention stage of the air conditioner's heating operation, the air outlet or fan is usually opened only when the indoor coil temperature is high enough.

[0003] However, there is usually a distance between the indoor heat exchanger and the air outlet. The indoor coil temperature is difficult to reflect the actual impact of the air conditioner's air output on the user. This can easily lead to inaccurate control of the air guide plate and fan under the anti-cold air control, causing cold air to blow in or no hot air to blow out for a long time, affecting the heating efficiency and user comfort. Summary of the Invention

[0011] Optionally, the step of determining the target outlet air temperature corresponding to the current rotation speed of the indoor fan of the air conditioner based on the indoor ambient temperature includes:

[0012] Obtain the reference air outlet temperature corresponding to the current speed of the indoor fan, and determine the temperature correction parameter based on the indoor ambient temperature; the reference air outlet temperature is the minimum air outlet temperature that the air conditioner needs to achieve when the indoor fan is running at the current speed.

[0013] The reference outlet air temperature is corrected according to the temperature correction parameter to obtain the target outlet air temperature.

[0014] Optionally, the step of determining the temperature correction factor based on the indoor ambient temperature includes:

[0015] The corresponding correction factor is determined based on the ambient temperature range in which the indoor ambient temperature falls.

[0016] The temperature correction parameter is obtained by correcting the target temperature difference value or the preset temperature difference value according to the correction coefficient;

[0020] If the indoor ambient temperature is greater than or equal to the second preset temperature, then the step of obtaining the temperature correction coefficient after correcting the target temperature difference value according to the correction coefficient is performed;

[0021] The second preset temperature is lower than the first preset temperature.

[0022] Optionally, after the step of determining the target outlet air temperature corresponding to the current speed of the indoor fan of the air conditioner based on the indoor ambient temperature, the method further includes:

[0023] When the outlet air temperature is greater than the target outlet air temperature, the running time of the indoor fan at the current speed is obtained;

[0024] When the runtime is greater than or equal to the target runtime, the step of determining that the indoor ambient temperature and the outlet air temperature have reached the preset conditions is executed.

[0025] Optionally, after the steps of controlling the indoor fan to increase its speed and / or controlling the first air guide plate at the air outlet of the air conditioner to adjust its guide angle to increase the downward airflow of the air conditioner, the method further includes:

[0026] Return to the steps of obtaining the indoor ambient temperature and the current air outlet temperature of the air conditioner, until the indoor fan speed reaches the target speed and / or the air guide angle of the first air guide plate reaches the set angle; wherein, the indoor ambient temperature is the initial temperature of the indoor environment when the air conditioner starts heating.

[0029] If the target air outlet temperature is greater than the set temperature threshold, then the step of controlling the first air guide plate of the air conditioner outlet to adjust the air guide angle to increase the downward air volume of the air conditioner when the air outlet temperature is greater than the target air outlet temperature is executed.

[0030] Optionally, the air conditioner further includes a second air guide plate disposed below the air outlet and an air duct communicating with the air outlet, wherein the first air guide plate is disposed above the air outlet;

[0032] While executing the step of controlling the first air guide plate to operate at the second air guide angle, the method also includes: controlling the second air guide plate to operate at the fourth air guide angle, so that the first air guide plate opens the upper area and the airflow in the air duct is guided downward into the room by the cooperation of the first air guide plate and the second air guide plate.

[0033] Furthermore, in order to achieve the above objectives, this application also proposes an air conditioner, which includes:

[0034] The housing is provided with an air outlet;

[0038] In addition, to achieve the above objectives, this application also proposes a computer-readable storage medium storing a control program for an air conditioner, which, when executed by a processor, implements the steps of the control method for the air conditioner as described in any of the preceding claims.

[0039] This invention proposes a control method for an air conditioner. When the air conditioner is in heating mode, this method combines indoor ambient temperature and outlet air temperature for cold air prevention control. Only when the indoor ambient temperature and outlet air temperature reach preset conditions is the fan speed increased and / or the angle of the air guide vane decreased to increase the downward airflow, thus achieving cold air prevention control. The outlet air temperature and indoor ambient temperature accurately represent the impact of the air conditioner's airflow on indoor users. Compared to cold air prevention control based on indoor coil temperature, the accuracy of the air guide vane and fan adjustment is effectively improved, ensuring that the air conditioner does not blow cold air onto people while quickly blowing out hot air to maintain heating efficiency and improve user comfort.

[0044] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0046] The main solution of this invention is: when the air conditioner starts heating, the indoor ambient temperature and the current air outlet temperature of the air conditioner are obtained; when the indoor ambient temperature and the air outlet temperature reach the preset conditions, the indoor fan is controlled to increase its speed, and / or the first air guide plate of the air outlet of the air conditioner is controlled to adjust the air guide angle to increase the downward air volume of the air conditioner.

[0047] Because in existing technologies, there is usually a distance between the indoor heat exchanger and the air outlet, the indoor coil temperature is difficult to reflect the actual impact of the air conditioner's output on the user. This can easily lead to inaccurate control of the air guide plate and fan under the anti-cold air control, which can easily cause cold air to blow into people or no hot air to blow out for a long time, affecting heating efficiency and user comfort.

[0048] The present invention provides the above-mentioned solution, which aims to improve the accuracy of cold air control, ensure that the air conditioner does not blow cold air on people while maintaining the heating efficiency of the air conditioner, and improve user comfort.

[0049] This invention provides an air conditioner. In this embodiment, the air conditioner is a wall-mounted air conditioner. In other embodiments, the air conditioner may also be a cabinet air conditioner, a ceiling-mounted air conditioner, a portable air conditioner, a window air conditioner, etc., depending on actual needs.

[0050] In this embodiment, refer to Figure 1 The air conditioner includes a housing 1, which has an air outlet 01 and an air guide plate 2 on the air outlet 01.

[0051] Specifically, the air guide plate 2 is movably disposed at the air outlet 01 and has different air guiding positions. For example, the air guide plate 2 can be rotated or slidably disposed at the air outlet 01. When the air guide plate 2 is in different air guiding positions, the air outlet 01 has different air outlet directions and / or air volume.

[0052] The number of air guide plates 2 can be set according to actual needs. In this embodiment, there are two air guide plates 2; in other embodiments, there may be one or more than two air guide plates 2.

[0053] Specifically, the housing 1 has an air duct connected to the air outlet 01, and the air duct contains an indoor heat exchanger and an indoor fan 3. Driven by the indoor fan 3, indoor air enters the air duct and undergoes heat exchange through the indoor heat exchanger. The heat-exchanged air is then sent into the indoor environment from the air outlet 01.

[0054] Specifically, in this embodiment, the air outlet 01 is provided with a first air guide plate 21 and a second air guide plate 22. The first air guide plate 21 is rotatably disposed on the upper side of the air outlet 01, and the second air guide plate 22 is rotatably disposed on the lower side of the air outlet 01. The area of ​​the surface of the first air guide plate 21 is smaller than the area of ​​the surface of the second air guide plate 22. When the second air guide plate 22 closes or partially blocks the air outlet 01, the first air guide plate 21 is located inside the second air guide plate 22. When the second air guide plate 22 is located inside the first air guide plate 21, it can adjust the direction or volume of the airflow blowing towards the first air guide plate 21 in the air duct; when the first air guide plate 21 opens the air outlet 01, the second air guide plate 22 can adjust the air outlet direction of the air outlet 01.

[0055] Furthermore, the air conditioner may also include a temperature detection module 4, which may include a first temperature sensor and a second temperature sensor. The first temperature sensor is used to detect the indoor ambient temperature, and the second temperature sensor is used to detect the air outlet temperature of the air conditioner. In this embodiment, the first temperature sensor is located at the return air vent of the air duct. In other embodiments, the first temperature sensor may also be located in the indoor environment where the air conditioner operates, and the second temperature sensor may be located at the air outlet of the air conditioner.

[0056] Furthermore, the air conditioner may also include a control device, see reference. Figure 2 The aforementioned air guide plate 2, indoor fan 3, and temperature detection module 4 are all connected to the control device here. The control device can control the operation of the air guide plate 2 and indoor fan 3, and can also acquire the temperature data detected by the temperature detection module 4.

[0057] The control device includes a processor 1001 (e.g., CPU), a memory 1002, and a timer 1003. The processor 1001 is connected to the memory 1002 and the timer 1003 via a communication bus. The memory 1002 can be a high-speed RAM or a stable, non-volatile memory, such as a disk drive. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0058] Those skilled in the art will understand that Figure 2 The device structure shown does not constitute a limitation on the device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0059] like Figure 2 As shown, the memory 1002, which is a computer-readable storage medium, may include a control program for an air conditioner. Figure 2 In the device shown, the processor 1001 can be used to call the control program of the air conditioner stored in the memory 1002 and execute the relevant steps of the control method of the air conditioner in the following embodiments.

[0060] This invention also provides a control method for an air conditioner, which is used to control the air conditioner described above.

[0061] Reference Figure 3 This application proposes an embodiment of a control method for an air conditioner. In this embodiment, the control method for the air conditioner includes:

[0062] Step S10: When the air conditioner is in heating mode, obtain the indoor ambient temperature and the current air outlet temperature of the air conditioner.

[0063] The air conditioner starting the heating mode here can be the air conditioner being powered on and running in heating mode, or it can be the air conditioner switching to heating mode after the defrosting mode ends, the air conditioner restarting the compressor after reaching the temperature and stopping, or the air conditioner restarting the compressor after the compressor stops for protection.

[0064] The indoor ambient temperature can be detected by the first temperature sensor located at the air return vent of the air conditioner. The outlet air temperature can be detected by the second temperature sensor located at the air outlet of the air conditioner.

[0065] Specifically, during the start-up phase of the air conditioner's heating operation, the indoor ambient temperature and outlet air temperature can be monitored in real time or at set intervals. Alternatively, the indoor ambient temperature and outlet air temperature can be monitored after the air conditioner has been running for a preset period of time since its start-up.

[0066] Step S20: When the indoor ambient temperature and the outlet air temperature reach the preset conditions, control the indoor fan to increase its speed, and / or control the first air guide plate of the air conditioner outlet to adjust the air guide angle to increase the downward air volume of the air conditioner.

[0067] When the indoor ambient temperature and the outlet air temperature reach the preset conditions, it means that even if the air conditioner increases the fan speed or the downward airflow, the user will not feel cold. At this time, increasing the indoor fan speed helps to ensure that the air conditioner does not blow cold air onto people.

[0068] When the indoor fan increases its speed, the speed can be increased according to a pre-set speed adjustment parameter, or the speed adjustment parameter can be determined based on the actual operating conditions of the air conditioner. For example, in this embodiment, when the indoor fan is currently operating at the first speed, it can be controlled to increase to the second speed by a preset speed increase margin.

[0069] The airflow volume and direction delivered to the indoor environment by the air conditioner will vary depending on the air guide angle of the first air guide plate. Specifically, adjusting the air guide angle can involve increasing or decreasing it; there is no fixed limit. The setting can be based on the selected reference position and the structural characteristics of the first air guide plate, as long as the downward airflow from the air conditioner is maintained after adjusting the air guide angle. In particular, when the air conditioner is in heating mode, the increased downward airflow facilitates the sinking of hot air, improving the air conditioner's heating efficiency in the indoor space.

[0070] In this embodiment, the air conditioner's air outlet has a first air guide plate on the upper side and a second air guide plate on the lower side. When the air outlet is open with the second air guide plate, the step of controlling the first air guide plate to adjust its air guiding angle can be performed. Specifically, the plane where the air outlet is located is defined as a reference plane, and the angle between the first air guide plate and the reference plane is the air guiding angle of the first air guide plate. When the air outlet is open with the second air guide plate, the air guiding angle of the first air guide plate can be reduced to increase the downward airflow of the air conditioner. Furthermore, in other embodiments, the first air guide plate can also be located below the air outlet, with the plane where the air outlet is located defined as a reference plane, and the angle between the first air guide plate and the reference plane being the air guiding angle of the first air guide plate. Increasing the air guiding angle of the first air guide plate can increase the downward airflow of the air conditioner.

[0071] When adjusting the air guide angle of the first air guide plate, the air guide angle can be adjusted according to a preset angle adjustment parameter, or it can be adjusted according to the angle adjustment parameter determined based on the actual operating conditions of the air conditioner. For example, based on the structure of the air outlet with a first air guide plate and a second air guide plate in this embodiment, when the first air guide plate is currently running at a first angle, it can be controlled to reduce the first air guide plate to a second angle according to a preset angle adjustment range. Based on this, the angle between the air outlet of the air conditioner and the horizontal direction can be increased, thereby increasing the air volume delivered by the air conditioner to the downward area.

[0072] In this embodiment, when the indoor ambient temperature and the outlet air temperature reach the preset conditions, the indoor fan speed is increased and the air guide angle of the first air guide plate is adjusted to increase the downward air volume of the air conditioner. In other embodiments, when the indoor ambient temperature and the outlet air temperature reach the preset conditions, the indoor fan speed can be increased while maintaining the air guide angle of the first air guide plate unchanged or the air guide angle can be adjusted in other ways. Alternatively, when the indoor ambient temperature and the outlet air temperature reach the preset conditions, the indoor fan can be controlled to maintain a certain speed while the air guide angle of the first air guide plate is adjusted to increase the downward air volume of the air conditioner.

[0073] This invention proposes a control method for an air conditioner. When the air conditioner is in heating mode, this method combines indoor ambient temperature and outlet air temperature for cold air prevention control. Only when the indoor ambient temperature and outlet air temperature reach preset conditions is the fan speed increased and / or the angle of the air guide vane decreased to increase the downward airflow from the air conditioner, thus achieving cold air prevention control. The outlet air temperature and indoor ambient temperature accurately represent the impact of the air conditioner's airflow on indoor users. Compared to cold air prevention control based on indoor coil temperature, the accuracy of the air guide vane and fan adjustment is effectively improved, ensuring that the air conditioner does not blow cold air onto people while quickly blowing out hot air to maintain heating efficiency and improve user comfort.

[0074] When the outlet air temperature is high, the air conditioner sends more heat downwards, which helps to improve heating efficiency, improve indoor temperature stratification, and enhance user comfort.

[0075] Furthermore, based on the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, reference is made to... Figure 4 After step S10, the method further includes:

[0076] Step S101: Determine the target air outlet temperature corresponding to the current speed of the indoor fan of the air conditioner based on the indoor ambient temperature;

[0077] Specifically, different indoor ambient temperatures result in different target outlet air temperatures corresponding to the current speed of the indoor fan. Conversely, when the indoor ambient temperature is the same, different indoor fan speeds correspond to different target outlet air temperatures.

[0078] The target outlet air temperature corresponding to the current speed is specifically the lowest temperature that the indoor fan needs to reach at the outlet air vent when running at the current speed during the process of increasing the outlet air temperature of the air conditioner. It can be used to distinguish whether the air conditioner outlet air temperature can reach the preset outlet air temperature (which is lower than the target outlet air temperature) after the indoor fan speed is increased, so as to improve heating efficiency and avoid cold air blowing in. It should be noted that the current speed here is a speed value greater than or equal to 0.

[0079] Specifically, multiple correspondences between air conditioner speed and outlet air temperature can be pre-established. These correspondences can take the form of mapping relationships, calculation relationships, etc. Different correspondences correspond to different indoor ambient temperatures. Based on this, one of the multiple correspondences is selected as the target correspondence according to the current indoor ambient temperature. Substituting the current air conditioner speed into the target correspondence yields the target outlet air temperature. Alternatively, there can be a single correspondence between air conditioner speed and outlet air temperature. Based on this correspondence, a reference outlet air temperature corresponding to the current air conditioner speed can be determined. The result of correcting the reference outlet air temperature according to the indoor ambient temperature is then used as the target outlet air temperature.

[0080] Step S102: When the outlet air temperature is greater than the target outlet air temperature, it is determined that the indoor ambient temperature and the outlet air temperature have reached the preset conditions.

[0081] When the current air outlet temperature of the air conditioner is higher than the target air outlet temperature, it indicates that the air outlet temperature of the air conditioner is high enough. Even if the speed is further increased or the first air guide plate is adjusted to increase the downward airflow, the air conditioner will not make the user feel cold. At the same time, it improves the heating efficiency of the air conditioner for the indoor environment, thereby improving the user's comfort.

[0082] Specifically, in this embodiment, step S101 includes: obtaining the reference air outlet temperature corresponding to the current rotation speed of the indoor fan; determining a temperature correction parameter based on the indoor ambient temperature; correcting the reference air outlet temperature based on the temperature correction parameter to obtain the target air outlet temperature.

[0083] The reference outlet air temperature is the minimum outlet air temperature that the air conditioner needs to achieve when the indoor fan is running at its current speed.

[0084] Different current fan speeds correspond to different reference outlet air temperatures; specifically, the higher the current speed, the higher the reference outlet air temperature. The relationship between the current fan speed and the reference outlet air temperature can be preset, such as through calculation or mapping. Based on this relationship, the reference outlet air temperature corresponding to the current speed can be determined. The target outlet air temperature is lower than this reference outlet air temperature.

[0085] Specifically, in this embodiment, different indoor fan speeds correspond to different outlet air temperature ranges; the higher the speed, the higher the temperature within the outlet air temperature range. Based on this, the outlet air temperature range corresponding to the current indoor fan speed can be determined, and the minimum critical temperature of the determined outlet air temperature range is used as the target outlet air temperature. The maximum critical value of this outlet air temperature range is specifically determined based on the target speed value required to be achieved after the indoor fan speed is subsequently increased; specifically, the maximum critical value is the reference outlet air temperature corresponding to the target speed value.

[0086] Temperature correction parameters specifically characterize the difference between the perceived temperature and the outlet air temperature during the air conditioner's heating process. Temperature correction parameters can include temperature correction amplitude or temperature correction ratio. Different indoor ambient temperatures correspond to different values ​​for the temperature correction parameter; the higher the indoor ambient temperature, the lower the target outlet air temperature obtained from the temperature correction parameter. For example, when the temperature correction parameter is a temperature correction amplitude, the higher the indoor ambient temperature, the larger the temperature correction amplitude can be, resulting in a lower target outlet air temperature. The correspondence between indoor ambient temperature and temperature correction parameters can be preset, and can be a mapping relationship, a calculation relationship, etc. Based on this correspondence, the temperature correction parameter corresponding to the current indoor ambient temperature can be determined. Specifically, multiple preset ambient temperatures can be set in advance, and the corresponding temperature correction parameter can be determined based on the quantitative relationship between the indoor ambient temperature and these multiple preset ambient temperatures.

[0087] In this embodiment, the temperature correction parameter is the temperature correction range, defined as ΔT, and the reference outlet air temperature is T. Cf The target outlet air temperature T CfK =T Cf -ΔT. In other embodiments, the temperature correction parameter is a temperature correction ratio, defined as p (less than 1), then the target outlet air temperature T CfK =T Cf *p.

[0088] In this embodiment, the minimum air outlet temperature of the air conditioner corresponding to the current rotation speed is corrected based on the indoor ambient temperature. The indoor ambient temperature can characterize the user's body temperature. Based on this, it can prevent the user from feeling cold due to the difference between the user's body temperature and the air outlet temperature when the air conditioner is controlling against cold air. This further improves the accuracy of the air conditioner's control against cold air, ensuring that the air conditioner's heating efficiency is improved while preventing cold air from blowing on people, and further improving user comfort.

[0089] Furthermore, in this embodiment, the step of determining the temperature correction parameter based on the indoor ambient temperature includes: determining a corresponding correction coefficient based on the ambient temperature range in which the indoor ambient temperature is located; and obtaining the temperature correction parameter after correcting the target temperature difference value or the preset temperature difference value based on the correction coefficient; wherein, the target temperature difference value is the temperature difference value between the indoor ambient temperature and the first preset temperature.

[0090] Specifically, the ambient temperature can be pre-divided into multiple ambient temperature ranges, with different preset correction parameters set for each range. Based on this, the current indoor ambient temperature is determined within one of these preset ranges, and the preset correction parameter corresponding to that range is obtained as the current correction coefficient. In this embodiment, the higher the temperature within the range, the larger the correction coefficient can be, thus resulting in a larger temperature correction parameter.

[0091] In this embodiment, the target temperature difference is the absolute value of the difference between the indoor ambient temperature and the first preset temperature; in other embodiments, the target temperature difference may also be the difference between the indoor ambient temperature and the first preset temperature. The first preset temperature is specifically a pre-set critical temperature of the indoor environment used to distinguish the degree of coldness felt by the human body when heating is activated. An indoor ambient temperature greater than or equal to the first preset temperature indicates that the user does not feel too cold; an indoor ambient temperature less than the preset temperature indicates that the user feels relatively cold.

[0092] The preset temperature difference value is specifically a pre-set compensation temperature value for the human body's perceived temperature, which can be stored in the air conditioner's memory.

[0093] The target temperature difference or preset temperature difference is a parameter value that characterizes the body's hot or cold state when heating is activated. The preset temperature difference is greater than the target temperature difference.

[0094] The preset temperature difference or target temperature difference is defined as D, and the correction coefficient is k. In this embodiment, the temperature correction parameter ΔT = D * k. In other embodiments, the temperature correction parameter can also be calculated by ΔT = D / k.

[0095] Here, the target temperature difference or preset temperature difference is corrected based on the correction coefficient corresponding to the temperature range of the indoor ambient temperature. This helps to obtain temperature correction parameters that accurately reflect the user's physical sensation, thereby ensuring the accuracy of the indoor fan and / or air guide plate control based on the subsequently obtained target air outlet temperature, and further improving the balance between the air conditioner's anti-cold air effect and heating efficiency.

[0096] Specifically, based on the actual operating conditions of the air conditioner (such as the current fan speed, indoor ambient temperature, current air guide angle of the air guide plate and / or compressor frequency, etc.), one of the target temperature difference value and the preset temperature difference value can be determined as the final temperature difference value. The final temperature difference value is then corrected according to the determined correction coefficient to obtain the current temperature correction parameter.

[0097] In this embodiment, the temperature difference value used to determine the temperature correction parameter is determined from the target temperature difference value and the preset temperature difference value based on the indoor ambient temperature.

[0098] After the step of obtaining the correction coefficient corresponding to the ambient temperature range, the method further includes: if the indoor ambient temperature is less than the second preset temperature, then performing the step of correcting the preset temperature difference value according to the correction coefficient to obtain the temperature correction parameter; if the indoor ambient temperature is greater than or equal to the second preset temperature, then performing the step of correcting the target temperature difference value according to the correction coefficient to obtain the temperature correction coefficient; wherein, the second preset temperature is less than the first preset temperature. If the indoor ambient temperature is lower than the second preset temperature, it indicates that the indoor temperature is too low when heating starts. In this case, the preset temperature difference value is used directly to determine the temperature correction parameter. While considering the human body's comfort, the air conditioner is prevented from having a sufficiently high outlet temperature under the determined target outlet temperature control to ensure the heating efficiency of the indoor environment. This prevents cold air from blowing into people while ensuring that the air conditioner heats the indoor environment with high heating efficiency. If the indoor ambient temperature is greater than or equal to the second preset temperature, it indicates that the indoor temperature is not too low when heating starts. In this case, the temperature correction parameter determined by combining the actual temperature difference between the indoor ambient temperature and the first preset temperature is used to obtain the target outlet temperature. This ensures the accuracy of the air conditioner's outlet temperature control, so as to achieve the best balance between anti-cold air effect and heating efficiency.

[0099] For example, let T10 be the indoor ambient temperature when the air conditioner is in heating mode, T11 be the first preset temperature, T12 be the second preset temperature, and ΔT be the temperature correction parameter. Then, when T10 ≥ T11, ΔT = (T10 - T11)K1; when T12 ≤ T10 < T11, ΔT = (T11 - T10)K2; when T10 < T12, ΔT = 4 * K3; where K1 is the correction coefficient when T10 ≥ T11; K2 is the correction coefficient when T12 ≤ T10 < T11; and K3 is the correction coefficient when T10 < T12.

[0100] In other embodiments, it is not necessary to select based on the indoor ambient temperature; one of the target temperature difference value and the preset temperature difference value can be directly used to determine the temperature correction parameter.

[0101] Furthermore, based on any of the above embodiments, another embodiment of the control method for the air conditioner of this application is proposed. In this embodiment, after step S20, the method further includes: returning to the step of obtaining the indoor ambient temperature and the current air outlet temperature of the air conditioner, until the rotational speed of the indoor fan reaches the target rotational speed and / or the air guiding angle of the first air guide plate reaches the set angle.

[0102] The indoor ambient temperature refers to the initial temperature of the indoor environment when the air conditioner starts heating. Specifically, the initial temperature refers to the first indoor ambient temperature detected after the air conditioner starts heating. In other words, regardless of the duration of operation after the air conditioner starts heating, the indoor ambient temperature obtained in each cycle of cyclically adjusting the indoor fan speed and / or the air guide angle is the first indoor ambient temperature detected after the air conditioner starts heating.

[0103] The target speed can be obtained by acquiring user-set parameters or by using the default parameters configured for the air conditioner.

[0104] The set angle is a pre-set critical air guiding angle for the first air guide plate when the air outlet direction of the air conditioner is downward. For example, in this embodiment, when the air conditioner is equipped with a first air guide plate and a second air guide plate, the first air guide plate is movably disposed on the upper side of the air outlet, and the second air guide plate is movably disposed on the lower side of the air outlet. When the first air guide plate operates at the set angle, the distance between the extension direction of the first air guide plate surface and the edge of the second air guide plate on the side away from the air outlet is greater than or equal to 0. Figure 1 (e).

[0105] Specifically, in step S20, when controlling the indoor fan to increase its speed and controlling the first air guide plate at the air outlet of the air conditioner to adjust its guide angle to increase the downward airflow of the air conditioner, if the indoor fan has reached the target speed but the guide angle has not reached the set angle, the process can return to the steps of obtaining the indoor ambient temperature and the outlet air temperature. When the indoor ambient temperature and the outlet air temperature subsequently reach the preset conditions, the indoor fan is controlled to maintain the target speed and the guide angle of the first air guide plate is adjusted. If the guide angle of the first air guide plate reaches the set angle, the indoor fan is controlled to maintain the target speed and the first air guide plate is controlled to maintain the set angle; if the guide angle of the first air guide plate has not reached the set angle, the process can return to the steps of obtaining the indoor ambient temperature and the outlet air temperature.

[0106] Additionally, in step S20, when controlling the indoor fan to increase its speed and controlling the first air guide plate at the air outlet of the air conditioner to adjust its guide angle to increase the downward airflow of the air conditioner, if the indoor fan has not reached the target speed but the guide angle has reached the set angle, the process can return to the steps of obtaining the indoor ambient temperature and the outlet air temperature. When the indoor ambient temperature and the outlet air temperature subsequently reach the preset conditions, the indoor fan is controlled to increase its speed and the first air guide plate is kept at the set angle. If the indoor fan speed reaches the target speed, the indoor fan is controlled to maintain the target speed and the first air guide plate is controlled to maintain the set angle; if the indoor fan speed does not reach the target speed, the process can return to the steps of obtaining the indoor ambient temperature and the outlet air temperature.

[0107] In this embodiment, by gradually increasing the indoor fan speed and / or gradually increasing the downward airflow of the air conditioner based on the initial indoor temperature and the outlet air temperature, it is beneficial to ensure that the cold air from the air conditioner does not blow on people while improving the heat exchange efficiency of the air conditioner and ensuring the comfort of indoor users after heating is started.

[0108] It should be noted that during the cycle, the current operating speed of the indoor fan and the speed after increasing the speed can be either a preset speed or a speed determined based on the actual operating conditions of the air conditioner. For example, the indoor fan may have multiple preset speeds that increase sequentially. When heating starts, the indoor fan operates at the minimum preset speed. When the outlet air temperature and the indoor ambient temperature reach the preset conditions, the indoor fan can switch to the next preset speed. During the operation of the indoor fan at the next preset speed, when the outlet air temperature and the indoor ambient temperature reach the preset conditions, the indoor fan can continue to switch to the next preset speed, and so on, until the indoor fan reaches the target operating speed.

[0109] Specifically, after step S10, steps S101 and S102 are included. After step S101, the method further includes: if the target air outlet temperature is less than or equal to the set temperature threshold, then when the air outlet temperature is less than the target air outlet temperature, the first air guide plate is controlled to operate at a first air guide angle to block the air outlet; when the air outlet temperature is greater than or equal to the target air outlet temperature, the first air guide plate is controlled to operate at a second air guide angle to open the air outlet and return to the step of obtaining the indoor ambient temperature and the current air outlet temperature of the air conditioner; if the target air outlet temperature is greater than the set temperature threshold, then the step of controlling the first air guide plate of the air conditioner air outlet to adjust the air guide angle to increase the downward air volume of the air conditioner when the air outlet temperature is greater than the target air outlet temperature is executed.

[0110] The temperature threshold setting is specifically used to distinguish whether the air conditioner's outlet temperature will make the user feel cold. The temperature threshold setting is a preset parameter.

[0111] Here, during the process of controlling the airflow to prevent cold air based on the indoor ambient temperature and the air conditioner's outlet temperature, if the target outlet temperature is less than or equal to the set temperature threshold, it indicates that the air conditioner's current outlet air being directly sent into the room would make the user feel cold. In this case, when the outlet temperature is lower than the target outlet temperature, the first air guide plate blocks the outlet to prevent the air conditioner's cold air from blowing directly on the user and affecting their comfort. Only when the outlet temperature is higher than the target outlet temperature will the outlet be opened through the first air guide plate. After opening the outlet, the air guide angle of the first air guide plate is adjusted based on the outlet temperature and the target outlet temperature, further pressing the air guide angle of the first air guide plate downwards. This effectively prevents cold air from blowing in, improves the air conditioner's heating efficiency, allows heat to quickly reach the lower space, improves the uniformity of the indoor ambient temperature, avoids indoor ambient temperature stratification, and improves the comfort of indoor users.

[0112] It should be noted that while controlling the operation of the first air guide plate according to the target air outlet temperature and the air outlet temperature, the speed of the indoor fan can also be adjusted simultaneously based on the target air outlet temperature and the air outlet temperature.

[0113] Specifically, in this embodiment, the air conditioner further includes a second air guide plate disposed below the air outlet and an air duct communicating with the air outlet, while the first air guide plate is disposed above the air outlet. Based on this, while executing the step of controlling the first air guide plate to operate at a first air guiding angle, the system also includes: controlling the second air guide plate to operate at a third air guiding angle, so that the first air guide plate blocks the upper area of ​​the air outlet, and the airflow in the air duct blows out from the lower area of ​​the air outlet and, guided by the second air guide plate, blows upwards into the room, such as... Figure 1 As shown in (a); while the step of controlling the first air guide plate to operate at the second air guide angle is being performed, it also includes: controlling the second air guide plate to operate at the fourth air guide angle, so that the first air guide plate opens the upper area, and the airflow in the air duct is guided downwards into the room by the cooperation of the first air guide plate and the second air guide plate, as shown in (a); Figure 1 As shown in (b). When the air outlet is equipped with a first air guide plate and a second air guide plate, the air outlet will not be closed when the air outlet temperature is very low. The cooperation of the first air guide plate and the second air guide plate allows the air conditioner to heat the indoor environment by blowing air upwards, while the cold air will not blow on the users below. After the air outlet temperature is increased, the cooperation of the first air guide plate and the second air guide plate allows the air outlet to be blown downwards, ensuring that the air outlet will not make the users feel cold, while improving the heating efficiency of the air conditioner for the indoor environment.

[0114] Specifically, in this embodiment, after the second air guide angle of the first air guide plate and the fourth air guide angle of the second air guide plate are used to open the air outlet, the angle adjustment process of the first air guide plate can be as follows: (The text abruptly ends here, so the translation stops as well.) Figure 1 (c) to Figure 1 As shown in (e), Figure 1 (e) The air guiding angle of the first air guide plate is a set angle.

[0115] Furthermore, based on any of the above embodiments, in this embodiment, after step S10, the method further includes: when the outlet air temperature is greater than the target outlet air temperature, obtaining the running time of the indoor fan at its current speed; when the running time is greater than or equal to the target time, executing the step of determining that the indoor ambient temperature and the outlet air temperature have reached the preset conditions. Specifically, the running time here starts counting from when the indoor fan switches from other speeds to the current speed. As the indoor fan maintains its current speed, the running time continuously accumulates, and the currently counted time is used as the running time. The target time can be a pre-set fixed parameter or a parameter determined based on the current operating status of the air conditioner. For example, the target time varies depending on the current speed of the indoor fan; specifically, the higher the current speed of the indoor fan, the shorter the target time can be, and the lower the current speed of the indoor fan, the longer the target time can be. Here, when the indoor fan runs for a sufficient period of time and the air conditioner's outlet temperature is high enough, it indicates that the air conditioner's outlet temperature is stable at a high level at the current speed of the indoor fan. Even if the indoor fan speed is further increased or the air guide plate is adjusted to increase the downward airflow, the air conditioner still has a high enough outlet temperature to prevent cold air from blowing into people. Therefore, at this time, the preset conditions are met, thereby achieving cold air prevention while improving the heating efficiency of the air conditioner.

[0116] To better understand the solution of this embodiment, the specific application of the air conditioner control method involved in this application embodiment is provided below:

[0117] 1. Cf≤CfU1k; The large guide (i.e., the second guide plate) is set to the anti-cold air angle α1 (i.e., the third guide angle), and the small guide (i.e., the first guide plate) is set to the anti-cold air angle A1 (i.e., the first guide angle). The fan rotates at the anti-cold air speed FAN1.

[0118] 2. When Cf U1k < Cf ≤ Cf U2K, the fan rotates at the anti-cold air speed FAN1 for a time Δt > Δt1; the large guide is set to the heating angle α1 (i.e., the fourth guide angle), and the small guide is set to the heating angle A1 (i.e., the second guide angle), and the fan rotates at the heating air speed FAN2.

[0119] 3. When Cf U2k < Cf ≤ Cf U3K, the fan rotates at the heating speed FAN2 for a time Δt > Δt1; the large deflector is set to the heating angle α2, the small deflector is set to the heating angle A2, and the fan rotates at the heating speed FAN3.

[0120] 4. When Cf U3k < Cf ≤ Cf U4K, the fan rotates at the heating speed FAN3 for a time Δt > Δt1; the large deflector is set to the heating angle α2, the small deflector is set to the heating angle A3, and the fan rotates at the heating speed FAN4.

[0121] 5. When Cf U4k < Cf ≤ Cf U5K, the fan rotates at the heating speed FAN4 for a time Δt > Δt1; the large deflector is set to the heating angle α2, the small deflector is set to the heating angle A4, and the fan rotates at the heating speed FAN5.

[0122] 6. When Cf U5k < Cf, the fan rotates at the heating speed FAN5 for a time Δt > Δt1; the large deflector is set to the heating angle α2, the small deflector is set to the heating angle A5, and the fan operates at the user - set speed.

[0123] FAN1, FAN2, FAN3, FAN4, FAN5 are the current rotational speeds of the indoor fan respectively, and FAN1 < FAN2 < FAN3 < FAN4 < FAN5. Cf is the current air outlet temperature of the air conditioner. CfU1k, Cf U2K, Cf U3K, Cf U4K, Cf U5K are the target air outlet temperatures corresponding to the current rotational speeds of the indoor fan being FAN1, FAN2, FAN3, FAN4, FAN5 respectively, which are determined according to the initial temperature of the indoor environment. Among them, CfU1k < Cf U2K < Cf U3K < Cf U4K < Cf U5K, and CfU1k is the above - mentioned set temperature threshold. A1, A2, A3, A4, A5 are the air deflector angles corresponding to the first air deflector respectively when the air outlet temperature of the air conditioner is greater than the target air outlet temperature corresponding to the current rotational speed of the indoor fan. Among them, A1 < A2 < A3 < A4 < A5, and A5 is the set angle. Then, as the air outlet temperature of the air conditioner increases, by adjusting the air deflector angle, the amount of air sent downward by the air conditioner continuously increases.
