[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. When the air conditioner is turned on for heating, the air outlet is blocked by the air guide plate when the indoor coil temperature is low, and the air outlet is only opened when the indoor coil temperature is high enough.

[0003] However, the indoor coil temperature is usually detected by a temperature sensor installed on the indoor heat exchanger. When the temperature sensor malfunctions, the air conditioner cannot accurately obtain the indoor coil temperature, causing the anti-cold air function to fail and affecting the comfort of indoor users. Summary of the Invention

[0007] When the exhaust temperature is greater than or equal to the target temperature, the air guide plate is controlled to operate at a second air guide angle to open the air outlet.

[0011] Optionally, the temperature data includes a first temperature value detected at a first moment and a second temperature value detected at a second moment, wherein the first moment is earlier than the second moment. After the step of acquiring the temperature data on the compressor discharge side and / or the current data of the compressor operation, the method further includes:

[0012] When the second temperature value is less than the first temperature value and the first temperature difference value is greater than the preset temperature difference, it is determined that the air conditioner has reached the preset condition;

[0013] Wherein, the first temperature difference value is the temperature difference between the first temperature value and the second temperature value.

[0014] Optionally, the current data includes a first current detected at a first moment and a second current detected at a second moment, wherein the first moment is earlier than the second moment. After the step of acquiring the temperature data on the compressor discharge side and / or the current data of the compressor operation, the method further includes:

[0015] When the second current is less than the first current and the difference between the first currents is greater than the preset current difference, it is determined that the air conditioner has met the preset condition.

[0016] Wherein, the first current difference is the current difference between the first current and the second current.

[0017] Optionally, after the steps of the air conditioner activating the heating mode include the air conditioner being powered on and activating the heating mode, controlling the air guide plate of the air conditioner's air outlet to operate at a first air guide angle to block the air outlet, and obtaining the exhaust temperature of the air conditioner's compressor, the method further includes:

[0018] When the exhaust temperature is greater than or equal to the target temperature and the running time of the heating mode is greater than or equal to the target duration, the step of controlling the air guide plate to operate at the second air guide angle to open the air outlet is executed.

[0019] Optionally, the process of activating the heating mode in the air conditioner includes activating the heating mode after defrosting or restarting the compressor in the heating mode. After the steps of controlling the air guide vane of the air conditioner's air outlet to operate at a first air guide angle to block the air outlet and obtaining the exhaust temperature of the air conditioner's compressor, the process further includes:

[0020] When the exhaust temperature is greater than or equal to the target temperature, and the temperature rise on the compressor exhaust side is greater than the target temperature change, the step of controlling the air guide plate to operate at a second air guide angle to open the air outlet is executed.

[0024] Optionally, the air guide plate is rotatably disposed on the lower side of the air outlet. At the first air guiding angle, the air guide plate forms a gap with the upper edge of the air outlet, and the internal airflow of the air conditioner is sent upward into the room through the gap under the guidance of the air guide plate. At the second air outlet angle, the air outlet direction is parallel to the surface of the air guide plate.

[0025] Furthermore, in order to achieve the above objectives, this application also proposes an air conditioner, the air conditioner comprising:

[0026] A compressor, wherein a temperature sensor is provided on the exhaust side of the compressor;

[0027] An air guide plate is provided at the air outlet of the air conditioner;

[0028] A control device, wherein the air guide plate and the temperature sensor are both connected to the control device, the control device comprising: a memory, a processor, and an air conditioner control program stored in the memory and executable on the processor, wherein when the air conditioner control program is executed by the processor, it implements the steps of the air conditioner control method as described in any of the preceding claims.

[0029] 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.

[0030] This invention proposes a control method for an air conditioner. When the air conditioner starts heating, a guide vane operates at a first guide angle to block the air outlet. When the compressor exhaust temperature is greater than or equal to the target temperature, the guide vane switches to a second guide angle to open the air outlet. Here, the compressor exhaust temperature characterizes the impact of the air conditioner's outlet temperature on the indoor user. The air outlet is only opened when the exhaust temperature indicates that the air conditioner's outlet air will not cause the user to feel cold. During this process, the prevention of cold air does not require detection of the indoor coil temperature. Therefore, even if the temperature sensor on the indoor heat exchanger malfunctions, it can effectively prevent cold air from blowing in, ensuring the comfort of the indoor user.

[0035] 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

[0036] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0037] The main solution of this invention is: when the air conditioner starts the heating mode, the air guide plate of the air outlet of the air conditioner is controlled to run at a first air guide angle to block the air outlet, and the exhaust temperature of the air conditioner compressor is obtained; when the exhaust temperature is greater than or equal to the target temperature, the air guide plate is controlled to run at a second air guide angle to open the air outlet.

[0038] In existing technologies, the indoor coil temperature controlled by the anti-cold air function is generally detected by a temperature sensor installed on the indoor heat exchanger. When the temperature sensor malfunctions, the air conditioner cannot accurately obtain the indoor coil temperature, causing the anti-cold air function to fail and affecting the comfort of indoor users.

[0039] The present invention provides the above-mentioned solution, which aims to effectively prevent cold air from blowing into people even when the temperature sensing bulb installed on the indoor heat exchanger malfunctions, thus ensuring the comfort of indoor users.

[0040] 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.

[0041] 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. The number of air guide plates 2 can be set according to actual needs. In this embodiment, there is one air guide plate 2; in other embodiments, there may be more than one air guide plate 2, for example, a first air guide plate is provided on the upper side of the air outlet 01, and a second air guide plate is provided on the lower side of the air outlet 01.

[0042] Specifically, the air guide plate 2 is movably disposed at the air outlet 01 and has different air guiding positions. 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.

[0043] 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. Driven by the indoor fan, 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.

[0044] Furthermore, the air conditioner also includes a refrigerant circulation loop, which comprises the aforementioned indoor heat exchanger, compressor, throttling device, and outdoor heat exchanger. During heating operation, the refrigerant discharged from the compressor flows sequentially through the indoor heat exchanger, throttling device, and outdoor heat exchanger before returning to the compressor. A temperature sensor is installed on the compressor's discharge side to detect the compressor's discharge temperature. Specifically, the temperature sensor can be located at the compressor's discharge port, or it can be located at the interface of the four-way valve connected to the compressor.

[0045] Furthermore, the air conditioner may also include a current detection module connected to the compressor, which can be used to detect the operating current of the compressor.

[0046] Furthermore, the air conditioner may also include a control device, see reference. Figure 2 The aforementioned air guide plate 2, temperature sensor 3, and current detection module 4 are all connected to the control device. The control device can be used to control the operation of the air guide plate 2, and also to read the exhaust temperature data detected by the temperature sensor 3 and the current data detected by the current detection module 4. Additionally, the indoor fan and compressor can also be connected to this control device, which can be used to control their operation.

[0047] The control device includes a processor 1001 (e.g., CPU), a memory 1002, etc. The processor 1001 and the memory 1002 are connected via a communication bus. The memory 1002 can be a high-speed RAM or a stable memory (non-volatile memory), such as a disk storage device. Optionally, the memory 1002 can also be a storage device independent of the aforementioned processor 1001.

[0048] 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.

[0049] 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 2In 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.

[0050] This invention also provides a control method for an air conditioner, which is used to control the air conditioner described above.

[0051] 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:

[0052] Step S10: When the air conditioner starts the heating mode, control the air guide plate of the air outlet of the air conditioner to run at a first air guide angle to block the air outlet, and obtain the exhaust temperature of the air conditioner's compressor.

[0053] The air conditioner here is in heating mode. This can be because the air conditioner is powered on and starts running in heating mode, or it can be switched to heating mode after the defrosting mode ends, or the air conditioner stops after reaching the desired temperature and then restarts the compressor, or the air conditioner's compressor stops for protection and then restarts the compressor.

[0054] At the first air guiding angle, the air guide plate can either completely close the air outlet or partially block its area. The angle between the airflow blowing towards the air outlet within the duct and the air guide plate is greater than a set angle threshold (e.g., 30 degrees). Defining the plane containing the air outlet as the reference plane, the first air guiding angle is the angle between the air guide plate and the reference plane when the air guide plate is in the first air guiding position. The first air guiding angle is less than the set angle. Specifically, in this embodiment, as... Figure 1 As shown in (a), the air guide plate is rotatably disposed on the lower side of the air outlet. At the first air guiding angle α1, the air guide plate forms a gap with the upper edge of the air outlet. Under the guidance of the air guide plate, the internal airflow of the air conditioner is sent upward into the room through the gap. At this time, the air outlet of the air conditioner does not blow on the user who is active in the lower area of ​​the space, and the air conditioner can adjust the indoor air temperature.

[0055] While the air guide plate is running at the first air guide angle, the temperature data detected by the temperature sensor installed on the exhaust side of the compressor is obtained in real time or at set intervals, thus obtaining the exhaust temperature here.

[0056] In this embodiment, the indoor fan is in a stopped state when the air guide plate is running at the first air guide angle. In other embodiments, the indoor fan may also be in a turned-on state when the air guide plate is running at the first air guide angle.

[0057] Step S20: When the exhaust temperature is greater than or equal to the target temperature, control the air guide plate to operate at a second air guide angle to open the air outlet.

[0058] The target temperature is the critical temperature on the compressor exhaust side used to determine whether the airflow from the air conditioner will be felt by the user. The target temperature can be a pre-set fixed temperature or a temperature determined based on the actual operation of the air conditioner. Specifically, the target temperature can be determined by acquiring the indoor ambient temperature, outdoor ambient temperature, and / or outdoor fan speed. In this embodiment, before step S20, the outdoor ambient temperature and the outdoor fan speed of the air conditioner can be acquired; the target temperature is then determined based on these two parameters. Different outdoor ambient temperatures and different outdoor fan speeds correspond to different target temperatures, ensuring that the compressor exhaust temperature accurately characterizes whether the air conditioner's exhaust will blow cold air into the user. It should be noted that the determination of the target temperature can be performed after step S10, simultaneously with step S10, or when the air conditioner starts heating.

[0059] At the second air guiding angle, the air guide plate opens the air outlet, and the angle between the airflow blowing towards the air outlet and the air guide plate in the air duct is less than a set angle threshold. Specifically, in this embodiment, at the second air outlet angle, the air outlet direction is parallel to the surface of the air guide plate, and the airflow in the air duct blows directly into the room. Defining the plane where the air outlet is located as the reference plane, the second air guiding angle is the angle between the air guide plate and the reference plane when the air guide plate is in the second air guiding position, and the second air guiding angle is greater than a set angle.

[0060] Specifically, in this embodiment, such as Figure 1 As shown in (b), the air conditioner is a wall-mounted air conditioner with the air guide plate rotated and located on the lower side of the air outlet. At the second air guide angle α2, the air guide plate and the airflow direction of the airflow blowing towards the air outlet in the air duct are parallel to the air guide plate. The air outlet in the air duct blows directly into the room. At this time, the air outlet of the air conditioner blows towards the user who is active in the area below the space.

[0061] In this embodiment, when the air guide plate is running at the second air guide angle, the indoor fan increases its speed. Specifically, if the exhaust temperature is greater than or equal to the target temperature when the air guide plate has been running at the second air guide angle for a preset time, the indoor fan can be controlled to increase its speed. This ensures the air conditioner's anti-cold air effect and improves user comfort.

[0062] This invention proposes a control method for an air conditioner. When the air conditioner starts heating, a guide vane operates at a first guide angle to block the air outlet. When the compressor exhaust temperature is greater than or equal to the target temperature, the guide vane switches to a second guide angle to open the air outlet. Here, the compressor exhaust temperature characterizes the impact of the air conditioner's outlet temperature on the indoor user. The air outlet is only opened when the exhaust temperature indicates that the air conditioner's outlet air will not cause the user to feel cold. This cold air prevention does not require detection of the indoor coil temperature. Therefore, even if the temperature sensor on the indoor heat exchanger malfunctions, it can effectively prevent cold air from blowing in, ensuring the comfort of the indoor user.

[0063] Specifically, in this embodiment, after step S10, when the exhaust temperature is less than the target temperature, the air guide plate can be controlled to maintain operation at the first air guide angle, thereby preventing cold air from blowing in.

[0064] Furthermore, in this embodiment, when the exhaust temperature is greater than or equal to the target temperature, the duration for which the air conditioner's exhaust temperature remains at or above the target temperature can be determined. If the duration exceeds a set duration, the step of controlling the air guide plate to operate at a second air guide angle to open the air outlet can be executed. Based on this, the air conditioner's anti-cold air effect can be guaranteed, improving user comfort.

[0065] Furthermore, in one implementation of this embodiment, the activation of the heating mode by the air conditioner includes the air conditioner being powered on and activating the heating mode. After step S10, it may further include: when the exhaust temperature is greater than or equal to the target temperature and the duration of the heating mode is greater than or equal to the target duration, executing the step of controlling the air guide plate to operate at a second air guide angle to open the air outlet. Here, the duration of the heating mode is specifically counted from the time of power-on. If the current counted duration is greater than or equal to the target duration and the exhaust temperature is greater than or equal to the target temperature, it can be considered that the air conditioner's airflow will not make the user feel cold. Therefore, the air conditioner is controlled to switch to the second air guide angle to ensure that the air conditioner does not blow cold air while improving heating efficiency.

[0066] The target duration can be a preset fixed parameter, a parameter set by the user, or a parameter determined based on the outdoor ambient temperature.

[0067] For example, when the air conditioner starts heating, the compressor starts, the air guide vane runs at the first air guide angle and detects the exhaust temperature. The exhaust temperature is defined as Tp. When Tp > 45℃ (target temperature) and the heating operation time is greater than 2 minutes, the air guide vane can be controlled to run at the second air guide angle.

[0068] Furthermore, in another implementation of this embodiment, the air conditioner starting the heating mode includes the air conditioner starting the heating mode after defrosting or restarting the compressor in the heating mode. After step S10, it may also include: when the exhaust temperature is greater than or equal to the target temperature and the temperature rise on the compressor exhaust side is greater than the target temperature change, the step of controlling the air guide plate to operate at a second air guide angle to open the air outlet is executed.

[0069] Specifically, the exhaust temperature can be detected at set intervals, for example, every 6 seconds.

[0070] The temperature rise here can be determined by the absolute value of the difference between the currently detected exhaust temperature and the exhaust temperature detected at the target time. Specifically, after step S10, if the air conditioner is in a state where the heating mode is started after defrosting or the compressor is restarted in the heating mode, and the exhaust temperature detected at the current time is greater than or equal to the target temperature, and the exhaust temperature detected at the current time is greater than the exhaust temperature detected at the target time, then the temperature rise can be determined based on the exhaust temperatures detected at the current time and the target time respectively.

[0071] For example, if we define the exhaust temperature detected at the current moment as Tp, the exhaust temperature detected at the target moment as Tp1, and the target temperature as 45℃, then when Tp>45℃ and Tp-Tp1>ΔTp (the change range of the target temperature), it can be considered that the outlet air temperature is relatively high and will not make the user feel cold. At this time, the air guide plate operates at the second air guide angle to achieve rapid heating of the indoor space.

[0072] In this embodiment, after the air conditioner finishes defrosting or when the compressor restarts, the air guide vane is controlled to operate at the second air guide angle only when the compressor exhaust temperature is high enough and the temperature rise is significant. This ensures that the air conditioner has sufficient heat exchange efficiency to regulate the indoor ambient temperature when the air guide vane operates at the second air guide angle, reducing the fluctuation of the indoor ambient temperature between the end of defrosting or the start of the compressor and before the start of defrosting or the start of the compressor, thus ensuring the comfort of indoor users.

[0073] 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 3 After step S20, the method further includes:

[0074] Step S30: During the process of the air guide plate running at the second air guide angle, acquire the temperature data of the compressor exhaust side and / or the current data of the compressor operation.

[0075] Temperature data can be specifically detected by the temperature sensor on the compressor's exhaust side. Current data can be specifically detected by the current detection module connected to the compressor.

[0076] Temperature data may include one or more temperature values. Current data may include one or more current values.

[0077] Step S40: When it is determined from the temperature data and / or the current data that the air conditioner has reached the preset conditions corresponding to defrosting start or reaching the temperature stop, the air guide plate is controlled to run at the first air guide angle to block the air outlet.

[0078] The preset conditions here are specifically the target conditions that the compressor's temperature and / or current data need to meet when the air conditioner starts defrosting in heating mode or when the indoor ambient temperature reaches the set temperature and the compressor needs to be turned off.

[0079] When the temperature and / or current data reach the preset conditions, it indicates that the air conditioner needs to start defrosting or the indoor ambient temperature needs to be turned off when the compressor is turned off or defrosting is in progress. Since the air conditioner stops heating when the compressor is off or defrosting is in progress, the air guide plate operates at the first air guide angle to block the air outlet. This ensures that the air conditioner will not blow cold air to the user when the compressor is off or defrosting is in progress, thus ensuring the comfort of the user indoors.

[0080] After step S40 here, you can return to step S10 above. So when entering heating mode after defrosting or after the compressor restarts after reaching the temperature and stopping, the air guide plate can be switched to the second air guide angle in time based on the exhaust temperature. This ensures that the air conditioner will not blow cold air on people while ensuring rapid heating of the indoor environment to meet user comfort.

[0081] Specifically, in one implementation of this embodiment, the temperature data includes a first temperature value detected at a first moment and a second temperature value detected at a second moment. The first moment is earlier than the second moment, and the second moment in this embodiment is the current moment. After the step of acquiring the temperature data on the compressor exhaust side and / or the current data of the compressor operation, the method further includes: when the second temperature value is less than the first temperature value and the first temperature difference value is greater than a preset temperature difference, determining that the air conditioner has reached the preset condition; wherein, the first temperature difference value is the temperature difference between the first temperature value and the second temperature value, specifically, it can be the absolute value of the difference between the first temperature value and the second temperature value. The preset temperature difference is specifically a critical temperature difference value that is pre-set to characterize the defrosting requirement or the temperature-reaching shutdown requirement of the air conditioner. Here, when the first temperature value is greater than the second temperature value and the first temperature difference value is greater than the preset temperature difference, it indicates that the temperature drop on the compressor exhaust side is large, which can be considered as caused by frost or the indoor ambient temperature reaching the set temperature. At this time, it can be determined that the air conditioner has the requirement to defrost and start or shut down the compressor, that is, the air conditioner has reached the preset condition.

[0082] Specifically, in another implementation of this embodiment, the current data includes a first current detected at a first moment and a second current detected at a second moment, where the first moment is earlier than the second moment, and the second moment in this embodiment is the current moment. After the step of acquiring the temperature data on the compressor exhaust side and / or the current data of the compressor operation, the method further includes: when the second current is less than the first current and the first current difference is greater than a preset current difference, determining that the air conditioner has reached the preset condition; wherein, the first current difference is the current difference between the first current and the second current, specifically the absolute value of the difference between the first current and the second current. The preset current difference is specifically a pre-set critical temperature difference value characterizing the defrosting requirement or the temperature-reaching shutdown requirement of the air conditioner. Here, when the first current is greater than the second current and the first current difference is greater than the preset current difference, it indicates that the compressor operating current value has decreased significantly, which can be considered as due to frost formation or the indoor ambient temperature reaching the set temperature. At this time, it can be determined that the air conditioner has a requirement to defrost and start or shut down the compressor, that is, the air conditioner has reached the preset condition.

[0083] Specifically, in another implementation of this embodiment, the current data includes a first current detected at a first moment and a second current detected at a second moment, and the temperature data includes a first temperature value detected at a first moment and a second temperature value detected at a second moment. The first moment is earlier than the second moment, and the second moment in this embodiment is the current moment. After the step of acquiring the temperature data on the compressor exhaust side and / or the current data of the compressor operation, the method further includes: when the second current is less than the first current, the first current difference is greater than a preset current difference, the second temperature value is less than the first temperature value, and the first temperature difference is greater than a preset temperature difference, it is determined that the air conditioner has reached the preset condition. Here, when the decrease in the compressor operating current value and the decrease in the compressor exhaust temperature are both large, it can be considered that it is due to frost formation or the indoor ambient temperature reaching the set temperature. At this time, it can be determined that the air conditioner has a need to defrost and start or shut down the compressor, that is, the air conditioner has reached the preset condition.

[0084] In existing technologies, whether an air conditioner needs to defrost or has reached the temperature for shutdown requires detection by an indoor temperature sensor. In this embodiment, the air conditioner's defrosting or temperature-reaching shutdown needs are characterized by temperature data and / or operating current data on the compressor's exhaust side. This ensures that even if the indoor temperature sensor malfunctions, the air conditioner will not blow cold air onto the user during the defrosting or temperature-reaching shutdown process, thus guaranteeing the user's comfort.

[0085] In other embodiments, when the temperature data is the currently detected temperature value and / or the current data is the currently detected current value, it can be determined that the air conditioner has reached the preset condition when the temperature value is less than the set temperature (less than or equal to the target temperature mentioned above) and / or the current value is less than the set current value.
