Description

Technical Field

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

[0002] To prevent air conditioners from blowing out cold air and causing discomfort when in heating mode, air conditioners typically have anti-cold air measures. Existing anti-cold air control schemes involve setting a deflector angle to prevent cold air from blowing directly onto the user. When the air conditioner is in heating mode, it initially controls the deflector to operate at the set anti-cold air angle, and then adjusts it back to the normal heating angle based on the indoor ambient temperature. While this method prevents cold air from blowing directly onto the user, when the air conditioner is in heating mode, the low indoor temperature and slow evaporator heating rate mean that the user cannot quickly experience warm air. Summary of the Invention

[0003] The main objective of this invention is to provide a control method for an air conditioner, an air conditioner, and a computer-readable storage medium, which aims to prevent cold air from blowing towards the user while increasing the heating rate of the air conditioner's evaporator, accelerating the heating rate of the indoor environment, and enabling the user to quickly experience hot air.

[0004] To achieve the above objectives, the present invention provides a control method for an air conditioner, the air conditioner comprising a housing, a first air guide plate, and a second air guide plate, the housing having an air outlet duct formed on the inner side of the housing for air circulation, the air outlet duct forming an air outlet on the outer peripheral wall of the housing; the first air guide plate being rotatably disposed in the air outlet duct, and the second air guide plate being rotatably disposed in the air outlet; the control method for the air conditioner includes:

[0005] When the air conditioner is turned on in heating mode, the initial temperature parameters are obtained;

[0006] When the value of the initial temperature parameter is less than the first preset threshold, the first air guide plate is set to the first air guide angle so that the first air guide plate partially blocks the air outlet of the air outlet duct.

[0007] When the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate is turned to the third air guide angle and the second air guide plate is turned to the fourth air guide angle so that air is blown out from the air outlet.

[0008] In one embodiment, after obtaining the initial temperature parameters when the air conditioner is in heating mode, the method further includes:

[0009] When the value of the initial temperature parameter is greater than or equal to the first preset threshold, the second air guide plate is set to the second air guide angle so that the second air guide plate partially blocks the air outlet of the air outlet duct.

[0010] When the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate is moved to the third air guide angle and the second air guide plate is moved to the fourth air guide angle so that air is blown out from the air outlet.

[0011] In one embodiment, the step of adjusting the first air guide plate to a first air guide angle when the initial temperature parameter value is less than a first preset threshold, so that the first air guide plate partially blocks the air outlet of the air outlet duct, includes:

[0012] When the value of the initial temperature parameter is less than a first preset threshold, it is determined whether the value of the initial temperature parameter is greater than a second preset threshold, wherein the second preset threshold is less than the first preset threshold;

[0013] When the value of the initial temperature parameter is greater than or equal to the second preset threshold, the first air guide plate is moved to the first air guide angle and the second air guide plate is moved to the fourth air guide angle, so that after the first air guide plate partially blocks the air outlet of the air duct, the air is blown out from the air outlet.

[0014] When the initial temperature parameter value is less than the second preset threshold, the first air guide plate is moved to the first air guide angle and the second air guide plate is moved to the second air guide angle, so that the first air guide plate partially blocks the air outlet of the air outlet duct, and the air outlet is then directed upward through the second air guide plate.

[0015] In one embodiment, the initial temperature parameter includes at least one of the following:

[0016] The initial indoor ambient temperature corresponding to the air conditioner;

[0017] The initial exhaust temperature of the air conditioner;

[0018] The initial temperature of the evaporator of the air conditioner.

[0019] In one embodiment, the anti-cold air exit condition includes at least one of the following:

[0020] The heating operation time of the air conditioner reaches the reference operation time;

[0021] The indoor ambient temperature of the air conditioner reaches the reference indoor ambient temperature.

[0022] The exhaust temperature of the air conditioner reaches the reference exhaust temperature;

[0023] The temperature of the evaporator in the air conditioner reaches the reference temperature of the evaporator.

[0024] In one embodiment, after the step of setting the first air guide plate to a third air guide angle and the second air guide plate to a fourth air guide angle so that air is blown out from the air outlet when the heating operation parameters of the air conditioner meet the anti-cold air exit condition, the method further includes:

[0025] When the air conditioner meets the defrosting conditions, the first air guide plate is turned to the first air guide angle so that the first air guide plate partially blocks the air outlet of the air outlet duct;

[0026] Switch to cooling mode;

[0027] After the air conditioner finishes defrosting, it switches to heating mode.

[0028] Return to the step of obtaining the initial temperature parameters.

[0029] In one embodiment, after the step of setting the first air guide plate to a third air guide angle and the second air guide plate to a fourth air guide angle so that air is blown out from the air outlet when the heating operation parameters of the air conditioner meet the anti-cold air exit condition, the method further includes:

[0030] Obtain the current indoor ambient temperature or the current temperature of the evaporator of the air conditioner;

[0031] When the current indoor ambient temperature or the current temperature of the evaporator of the air conditioner is greater than the third preset threshold, the compressor of the air conditioner is turned off, and the second air guide plate is set to the second air guide angle so that the second air guide plate partially blocks the air outlet of the air duct.

[0032] After the compressor restarts, return to the step of obtaining the initial temperature parameters.

[0033] In addition, to achieve the above objectives, the present invention also provides an air conditioner, the air conditioner including a first air guide plate, a second air guide plate, 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 described in any of the above claims.

[0034] In one embodiment, the air conditioner includes a housing having an air outlet duct formed inside the housing for air circulation, the air outlet duct forming an air outlet on the outer peripheral wall of the housing; a first air guide plate is rotatably disposed in the air outlet duct, and a second air guide plate is rotatably disposed in the air outlet.

[0035] In addition, to achieve the above objectives, the present invention also provides a computer-readable storage medium storing a control program for an air conditioner, wherein the control program for the air conditioner, when executed by a processor, implements the steps of the control method for the air conditioner described in any of the above claims.

[0036] This invention proposes a control method for an air conditioner, an air conditioner, and a computer-readable storage medium. The air conditioner includes a housing, a first air guide plate, and a second air guide plate. The housing has an air outlet duct formed inside the housing for air circulation, and an air outlet is formed on the outer peripheral wall of the housing. The first air guide plate is rotatably disposed in the air outlet duct, and the second air guide plate is rotatably disposed in the air outlet. When the air conditioner is in heating mode, by acquiring initial temperature parameters, if the parameter value of the initial temperature parameters is less than a first preset threshold, the first air guide plate is turned to a first air guide angle so that the first air guide plate partially blocks the air outlet duct. When the heating operation parameters of the air conditioner meet the anti-cold air exit condition, the first air guide plate is turned to a third air guide angle, and the second air guide plate is turned to a fourth air guide angle so that air is blown out from the air outlet. This solution controls the air guiding angle of the first air guide plate when the air conditioner is in heating mode, so that it partially blocks the air outlet duct, reducing the air volume of the air conditioner. This allows some of the air volume to return to the evaporator to heat it up, thereby preventing cold air from blowing onto the user while increasing the heating rate of the evaporator and refrigerant, so that the indoor temperature can be raised quickly and the user can quickly experience hot air.

[0050] It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0051] As one implementation scheme, refer to Figure 1 , Figure 1 This is a schematic diagram of the hardware architecture of the air conditioner involved in the embodiments of the present invention, as shown below. Figure 1 As shown, the air conditioner may include a processor 101, such as a CPU, a memory 102, a communication bus 103, a first air guide plate 104, and a second air guide plate 105, wherein the communication bus 103 is used to realize the connection and communication between these modules.

[0052] Memory 102 can be high-speed RAM or stable memory (non-volatile memory), such as disk storage. Figure 1 As shown, the memory 102, which is a computer-readable storage medium, may include a control program for an air conditioner; and the processor 101 may be used to call the control program for the air conditioner stored in the memory 102 and perform the following operations:

[0053] When the air conditioner is turned on in heating mode, the initial temperature parameters are obtained;

[0054] When the value of the initial temperature parameter is less than the first preset threshold, the first air guide plate is set to the first air guide angle so that the first air guide plate partially blocks the air outlet of the air outlet duct.

[0055] When the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate is turned to the third air guide angle and the second air guide plate is turned to the fourth air guide angle so that air is blown out from the air outlet.

[0056] In one embodiment, the processor 101 can be used to call the control program of the air conditioner stored in the memory 102 and perform the following operations:

[0057] When the value of the initial temperature parameter is greater than or equal to the first preset threshold, the second air guide plate is set to the second air guide angle so that the second air guide plate partially blocks the air outlet of the air outlet duct.

[0058] When the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate is moved to the third air guide angle and the second air guide plate is moved to the fourth air guide angle so that air is blown out from the air outlet.

[0059] In one embodiment, the processor 101 can be used to call the control program of the air conditioner stored in the memory 102 and perform the following operations:

[0060] When the value of the initial temperature parameter is less than a first preset threshold, it is determined whether the value of the initial temperature parameter is greater than a second preset threshold, wherein the second preset threshold is less than the first preset threshold;

[0061] When the value of the initial temperature parameter is greater than or equal to the second preset threshold, the first air guide plate is moved to the first air guide angle and the second air guide plate is moved to the fourth air guide angle, so that after the first air guide plate partially blocks the air outlet of the air duct, the air is blown out from the air outlet.

[0062] When the initial temperature parameter value is less than the second preset threshold, the first air guide plate is moved to the first air guide angle and the second air guide plate is moved to the second air guide angle, so that the first air guide plate partially blocks the air outlet of the air outlet duct, and the air outlet is then directed upward through the second air guide plate.

[0063] In one embodiment, the processor 101 can be used to call the control program of the air conditioner stored in the memory 102 and perform the following operations:

[0064] When the air conditioner meets the defrosting conditions, the first air guide plate is turned to the first air guide angle so that the first air guide plate partially blocks the air outlet of the air outlet duct;

[0065] Switch to cooling mode;

[0066] After the air conditioner finishes defrosting, it switches to heating mode.

[0067] Return to the step of obtaining the initial temperature parameters.

[0068] In one embodiment, the processor 101 can be used to call the control program of the air conditioner stored in the memory 102 and perform the following operations:

[0069] Obtain the current indoor ambient temperature or the current temperature of the evaporator of the air conditioner;

[0070] When the current indoor ambient temperature or the current temperature of the evaporator of the air conditioner is greater than the third preset threshold, the compressor of the air conditioner is turned off, and the second air guide plate is set to the second air guide angle so that the second air guide plate partially blocks the air outlet of the air duct.

[0071] After the compressor restarts, return to the step of obtaining the initial temperature parameters.

[0072] Reference Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of the control method for an air conditioner according to the present invention. The control method for the air conditioner includes:

[0073] Step S10: When the air conditioner turns on the heating mode, the initial temperature parameters are obtained;

[0074] In this embodiment, the existing air conditioner's anti-cold-wind measure involves setting the air deflector to an anti-cold-wind angle when the air conditioner is in heating mode to prevent cold air from blowing directly onto the user, until the refrigerant temperature rises and the air conditioner blows out hot air, at which point the air deflector is set back to the normal heating angle. While setting the air deflector to an anti-cold-wind angle can prevent cold air from blowing directly onto the user, the existing anti-cold-wind measure only considers the anti-cold-wind angle and does not take into account the heating rate of the evaporator and refrigerant. When the air conditioner is in heating mode, the refrigerant and evaporator heat up relatively slowly, resulting in a slow rise in indoor ambient temperature. Consequently, users need to stay in a low-temperature indoor environment for a long time and cannot quickly experience hot air.

[0075] Based on this technical problem, the present invention proposes a control method for an air conditioner. When the air conditioner is in heating mode, the air guide angle of the air guide plate is controlled to partially block the air outlet of the air conditioner, reducing the air volume. The blocked air returns to the evaporator to heat the evaporator and refrigerant, thereby accelerating the heating rate of the refrigerant and evaporator, and thus increasing the heating rate of the indoor environment. This achieves the goal of preventing cold air from blowing directly on the user while increasing the heating rate of the refrigerant, allowing the indoor temperature to rise quickly and the user to experience warm air rapidly.

[0076] In this embodiment, the air conditioner is the executing entity of the air conditioner control method. Of course, in other embodiments, the executing entity can be other control devices capable of controlling the air conditioner; this embodiment does not limit this. (Refer to...) Figure 7 , Figure 7 This is a schematic diagram of the air guide plate involved in the embodiment of the present invention. Figure 1 The air conditioner involved in this invention includes a housing 1, a first air guide plate 2, and a second air guide plate 3. The housing 1 has an air outlet duct (not shown in the figure) formed inside the housing 1 for air circulation, and an air outlet (not shown in the figure) is formed on the outer peripheral wall of the housing 1. The first air guide plate 2 is rotatably disposed in the air outlet duct, and the second air guide plate 3 is rotatably disposed in the air outlet. By controlling the air guiding angle of the first air guide plate 2, the air volume and air direction of the air outlet duct of the air conditioner can be controlled. By controlling the air guiding angle of the second air guide plate 3, the air direction and air volume of the air outlet of the air conditioner can be controlled. That is, by controlling the air guiding angles of the first air guide plate 2 and the second air guide plate 3, the first air guide plate 2 and the second air guide plate 3 cooperate with each other, and the air volume and air direction of the air conditioner can be reasonably controlled.

[0077] In this embodiment, when the air conditioner is turned on in heating mode, initial temperature parameters are acquired. These initial temperature parameters refer to the relevant temperature information when the air conditioner first turns on in heating mode. The initial temperature parameters may include at least one of the following: the initial indoor ambient temperature corresponding to the air conditioner's initial heating mode, the initial exhaust temperature of the air conditioner's initial heating mode, and the initial temperature of the air conditioner's evaporator's initial heating mode. Of course, in other embodiments, the initial temperature parameters can be determined according to actual conditions; this embodiment does not limit this.

[0078] Specifically, the air conditioner can be equipped with a sensor to collect initial temperature parameters. The air conditioner can collect these initial temperature parameters through this sensor. The air conditioner can have at least one of the following: an indoor ambient temperature sensor, an exhaust temperature sensor, and an evaporator temperature sensor. When the air conditioner is in heating mode, it can collect the initial temperature parameters through at least one of these sensors. For example, when the air conditioner is in heating mode, it can obtain the initial indoor ambient temperature by collecting the indoor ambient temperature from the indoor ambient temperature sensor.

[0079] Step S20: When the value of the initial temperature parameter is less than the first preset threshold, the first air guide plate is set to the first air guide angle so that the first air guide plate partially blocks the air outlet of the air outlet duct.

[0080] In this embodiment, after obtaining the initial temperature parameter, the air conditioner determines whether the parameter value is less than a first preset threshold. If the initial temperature parameter value is less than the first preset threshold, the first air guide plate 2 of the air conditioner is adjusted to a first air guide angle, so that the first air guide plate 2 partially blocks the airflow from the air duct of the air conditioner. The first air guide angle refers to the angle at which the first air guide plate 2 prevents cold air from entering the air duct. The first air guide angle can be selected from 40 degrees to 80 degrees. Of course, in other embodiments, the first air guide angle can be determined according to the specific structure and performance of the air conditioner; this embodiment does not limit this. It should be noted that the first preset threshold varies depending on the initial temperature parameter, and the first preset threshold can be set according to actual needs; this embodiment does not limit this.

[0081] When the first air guide plate 2 is set to the first air guide angle, it can prevent cold air from blowing directly to the user and block the air outlet of the air conditioner. This allows some of the blocked air to return to the evaporator. The air returning to the evaporator can heat up the evaporator and refrigerant, thereby increasing the heating rate of the evaporator and refrigerant and accelerating the heating rate of the indoor environment. Users can experience hot air more quickly.

[0082] Specifically, refer to Figure 8 , Figure 8 This is a schematic diagram of the air guide plate involved in the embodiment of the present invention. Figure 2 After obtaining the initial temperature parameters, if the value of the initial temperature parameters is less than the first preset threshold, the air conditioner will open the first air guide plate 2 to the first air guide angle A1 so that the first air guide plate 2 partially blocks the air outlet of the air conditioner, reduces the air volume of the air conditioner, and uses the air returning to the evaporator to increase the heating rate of the evaporator and refrigerant, accelerate the heating rate of the indoor environment, and allow users to quickly experience hot air.

[0083] It should be noted that when the initial temperature parameter value is less than the first preset threshold, and the first air guide plate 2 reaches the first air guide angle, the second air guide plate 3 can reach any angle. In this embodiment, the air guide angle of the second air guide plate 3 is not limited.

[0084] Step S30: When the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate is moved to the third air guide angle and the second air guide plate is moved to the fourth air guide angle so that air is blown out from the air outlet.

[0085] In this embodiment, during the operation of the air conditioner, the heating operation parameters of the air conditioner are acquired. When the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate 2 of the air conditioner is moved to the third air guide angle, and the second air guide plate 3 is moved to the fourth air guide angle so that air is blown out from the air outlet of the air conditioner. In this context, the third air guide angle refers to the normal heating angle of the first air guide plate 2, and the fourth air guide angle refers to the normal heating angle of the second air guide plate 3. Heating operation parameters refer to relevant operating parameters during the air conditioner's heating process. These parameters may include at least one of the following: the air conditioner's heating operation duration, the corresponding indoor ambient temperature, the air conditioner's exhaust temperature, and the air conditioner's evaporator temperature. The anti-cold air exit condition may include at least one of the following: the air conditioner's heating operation duration reaches a reference operation duration, the corresponding indoor ambient temperature reaches a reference indoor ambient temperature, the air conditioner's exhaust temperature reaches a reference exhaust temperature, and the air conditioner's evaporator temperature reaches a reference evaporator temperature. When the air conditioner meets the anti-cold air exit condition, it indicates that the refrigerant and evaporator temperatures have risen to a suitable level, which will not cause discomfort to the user. At this time, there is no need to perform anti-cold air operation, and the air conditioner can switch to normal heating operation. The reference indoor ambient temperature, reference exhaust temperature, reference operation duration, and evaporator reference temperature can be set according to actual needs; this embodiment does not limit these settings.

[0086] Specifically, refer to Figure 9 , Figure 9 This is a schematic diagram of the air guide plate involved in the embodiment of the present invention. Figure 3 When the air conditioner turns on the heating mode and the first air guide plate 2 operates at the first air guide angle, the air conditioner can obtain the heating operation parameters in real time and determine whether the heating operation parameters meet the anti-cold air exit conditions. When the heating operation parameters meet the anti-cold air exit conditions, the first air guide plate 2 of the air conditioner is turned to the third air guide angle A2 and the second air guide plate 3 is turned to the fourth air guide angle a2 so that air is blown out from the air outlet. At this time, the air conditioner has completed the anti-cold air operation and the air conditioner enters the normal heating mode for heating operation. The first air guide plate 2 and the second air guide plate 3 are both at their normal heating angles.

[0087] In the technical solution provided in this embodiment, by acquiring the initial temperature parameter, when the parameter value of the initial temperature parameter is less than a first preset threshold, the first air guide plate 2 is set to the first air guide angle A1, so that the first air guide plate 2 partially blocks the air outlet of the air duct; when the heating operation parameters of the air conditioner meet the anti-cold air exit condition, the first air guide plate 2 is set to the third air guide angle A2, and the second air guide plate 3 is set to the fourth air guide angle a2, so that air is blown out from the air outlet. When the air conditioner is in heating mode, this solution controls the air guide angle of the first air guide plate 2 to partially block the air outlet of the air conditioner, reducing the air volume of the air conditioner, and returning some air volume to the evaporator to heat the refrigerant and the evaporator. This achieves the goal of preventing cold air from blowing directly to the user while increasing the heating rate of the evaporator and the refrigerant, so that the indoor temperature can be raised quickly and the user can quickly experience hot air.

[0088] Reference Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of the control method for an air conditioner of the present invention. Based on the first embodiment, the steps of S20 above include:

[0089] Step S21: When the parameter value of the initial temperature parameter is less than the first preset threshold, determine whether the parameter value of the initial temperature parameter is greater than the second preset threshold, wherein the second preset threshold is less than the first preset threshold;

[0090] Specifically, after obtaining the initial temperature parameter, the air conditioner determines whether the parameter value of the initial temperature parameter is less than a first preset threshold. If the parameter value of the initial temperature parameter is less than the first preset threshold, it determines whether the parameter value of the initial temperature parameter is greater than a second preset threshold, wherein the second preset threshold is less than the first preset threshold.

[0091] Step S22: When the parameter value of the initial temperature parameter is greater than or equal to the second preset threshold, the first air guide plate is moved to the first air guide angle and the second air guide plate is moved to the fourth air guide angle, so that after the first air guide plate partially blocks the air outlet of the air duct, the air is blown out from the air outlet.

[0092] Specifically, refer to Figure 10 , Figure 10 This is a schematic diagram of the air guide plate involved in the embodiment of the present invention. Figure 4 When the initial temperature parameter value is greater than or equal to the second preset threshold, the first air guide plate 2 is set to the first air guide angle A1, and the second air guide plate 3 is set to the fourth air guide angle a2, so that after the first air guide plate 2 partially blocks the air outlet of the air conditioner, the air outlet of the air conditioner blows outward from the air outlet.

[0093] When the initial temperature parameter value is greater than or equal to the second preset threshold, by setting the first air guide plate 2 to the first air guide angle A1 and the second air guide plate 3 to the fourth air guide angle a2, on the one hand, cold air can be prevented from blowing directly to the user, and on the other hand, the first air guide plate 2 partially blocks the air outlet of the air conditioner, reducing the air volume at the outlet. The blocked air returns to the evaporator, and the returned air heats up the evaporator and refrigerant, reducing the temperature drop of the evaporator and refrigerant caused by the increase in air volume. This accelerates the temperature rise rate of the evaporator and refrigerant in the early stage of the air conditioner's operation, and accelerates the indoor temperature rise rate, allowing users to quickly experience hot air.

[0094] Step S23: When the value of the initial temperature parameter is less than the second preset threshold, the first air guide plate is moved to the first air guide angle and the second air guide plate is moved to the second air guide angle, so that after the first air guide plate partially blocks the air outlet of the air outlet duct, the air outlet is directed upward through the second air guide plate.

[0095] Specifically, refer to Figure 11 , Figure 11 This is a schematic diagram of the air guide plate involved in the embodiment of the present invention. Figure 5 When the initial temperature parameter value is less than the second preset threshold, the first air guide plate 2 is moved to the first air guide angle A1 and the second air guide plate 3 is moved to the second air guide angle a1. This allows the first air guide plate 2 to partially block the air outlet of the air conditioner, and the air outlet of the air conditioner is then directed upwards through the second air guide plate 3. The second air guide angle refers to the anti-cold air angle of the second air guide plate 3, which can be selected from 25 degrees to 80 degrees. Of course, in other embodiments, the second air guide angle can be determined according to the specific structure and performance of the air conditioner; this embodiment does not limit this.

[0096] When the initial temperature parameter value is less than the second preset threshold, by setting the first air guide plate 2 to the first air guide angle A1 and the second air guide plate 3 to the second air guide angle a1, on the one hand, cold air can be prevented from blowing directly to the user, and on the other hand, the first air guide plate 2 partially blocks the air outlet of the air conditioner, reducing the air volume at the air outlet of the air conditioner. The blocked air returns to the evaporator, and the returned air heats up the evaporator and refrigerant, accelerating the temperature rise rate of the evaporator in the early stage of the air conditioner's operation, accelerating the temperature rise rate of the room, and allowing the user to quickly experience hot air.

[0097] In the technical solution provided in this embodiment, when the parameter value of the initial temperature parameter is less than the first preset threshold, the air guiding angle of the first air guide plate 2 and the second air guide plate 3 is controlled by judging the relationship between the parameter value of the initial temperature parameter and the second preset threshold. This prevents cold air from blowing directly to the user while accelerating the heating rate of the evaporator and refrigerant of the air conditioner, so that the user can quickly experience hot air.

[0098] Reference Figure 4 , Figure 4 This is a flowchart illustrating a third embodiment of the control method for an air conditioner according to the present invention. Based on the first embodiment, after step S10 above, it further includes:

[0099] Step S40: When the parameter value of the initial temperature parameter is greater than or equal to the first preset threshold, the second air guide plate is set to the second air guide angle so that the second air guide plate partially blocks the air outlet of the air outlet duct.

[0100] Specifically, refer to Figure 12 , Figure 12 This is a schematic diagram of the air guide plate involved in the embodiment of the present invention. Figure 6 After the air conditioner obtains the initial temperature parameters, when the parameter value of the initial temperature parameters is greater than or equal to the first preset threshold, the second air guide plate 3 is set to the second air guide angle a1 so that the second air guide plate 3 partially blocks the air outlet of the air conditioner.

[0101] It should be noted that when the second air guide plate 3 is set to the second air guide angle a1, the first air guide plate 2 can be set to any angle. Usually, the first air guide plate 2 can be set to the third air guide angle A2.

[0102] When the initial temperature parameter value is greater than or equal to the first preset threshold, by setting the second air guide plate 3 to the second air guide angle a1, it can prevent cold air from blowing directly to the user. On the other hand, by partially blocking the air outlet of the air conditioner with the second air guide plate 3, the air volume at the air outlet of the air conditioner is reduced. The blocked air returns to the evaporator, and the returned air is used to heat up the evaporator and refrigerant. In addition, when the initial temperature parameter value is greater than or equal to the first preset threshold, the evaporator temperature rises relatively quickly. Therefore, it can accelerate the temperature rise rate of the evaporator and refrigerant in the early stage of air conditioner startup, speed up the indoor temperature rise rate, and allow users to quickly experience hot air.

[0103] Furthermore, when the heating operation parameters of the air conditioner meet the conditions for preventing cold air from exiting, the first air guide plate 2 is set to the third air guide angle A2, and the second air guide plate 3 is set to the fourth air guide angle a2, so that air is blown out from the air outlet of the air conditioner. For details, please refer to the content of Embodiment 1, which will not be repeated here.

[0104] Reference Figure 5 , Figure 5 This is a flowchart illustrating the fourth embodiment of the control method for an air conditioner of the present invention. Based on the first embodiment, after step S30 above, it further includes:

[0105] Step S50: When the air conditioner meets the defrosting conditions, the first air guide plate is turned to the first air guide angle so that the first air guide plate partially blocks the air outlet of the air outlet duct.

[0106] Step S60: Switch to cooling mode.

[0107] Step S70: After the air conditioner finishes defrosting, switch to heating mode and return to the step of obtaining the initial temperature parameters.

[0108] Specifically, after the air conditioner exits the anti-cold air operation, if the defrosting conditions are met during the air conditioner's heating operation, the first air guide plate 2 of the air conditioner is set to the first air guide angle A1 so that the first air guide plate 2 partially blocks the air outlet of the air conditioner. Then, the air conditioner is switched to cooling mode to defrost. After the air conditioner finishes defrosting, it is switched to heating mode. When the air conditioner is running in heating mode, the step of obtaining the initial temperature parameters is returned. For details, please refer to the content of Embodiment 1. This embodiment will not be repeated here.

[0109] Since the evaporator temperature drops rapidly during defrosting, by setting the first air guide plate 2 to the first air guide angle A1, it can prevent the cold air at the beginning of defrosting from blowing directly on the user. On the other hand, after defrosting, because the first air guide plate 2 is at the first air guide angle A1, the air volume at the air outlet is reduced, which can reduce the temperature drop of the evaporator and refrigerant caused by the increase in air volume. This can accelerate the rate of temperature rise of the evaporator and refrigerant at the beginning of startup, accelerate the rate of temperature rise of the indoor environment, and allow the user to quickly experience hot air.

[0110] In the technical solution provided in this embodiment, when the air conditioner meets the defrosting conditions, the first air guide plate 2 of the air conditioner is set to the first air guide angle A1, so that the first air guide plate 2 partially blocks the air outlet of the air duct, which can prevent the cold air during the defrosting process from blowing directly to the user. At the same time, when the air conditioner switches back to the heating mode, it can increase the temperature rise rate of the evaporator and refrigerant in the initial stage of start-up, accelerate the rise rate of the indoor ambient temperature, and allow the user to quickly experience the hot air.

[0111] Reference Figure 6 , Figure 6 This is a flowchart illustrating the fifth embodiment of the control method for an air conditioner of the present invention. Based on the first embodiment, after step S30 above, it further includes:

[0112] Step S80: Obtain the current indoor ambient temperature or the current temperature of the evaporator of the air conditioner;

[0113] Specifically, after the air conditioner is deactivated from anti-cold air operation, during the heating operation, the air conditioner collects the current indoor ambient temperature in real time through an indoor temperature sensor or collects the current temperature of the air conditioner's evaporator in real time through an evaporator temperature sensor.

[0114] Step S90: When the current indoor ambient temperature or the current temperature of the evaporator of the air conditioner is greater than the third preset threshold, turn off the compressor of the air conditioner and turn the second air guide plate to the second air guide angle so that the second air guide plate partially blocks the air outlet of the air outlet duct.

[0115] Specifically, after obtaining the current indoor ambient temperature or the current temperature of the air conditioner's evaporator, the air conditioner determines whether the current indoor ambient temperature or the current temperature of the evaporator is greater than a third preset threshold. If the current indoor ambient temperature or the current temperature of the evaporator is greater than the third threshold, the air conditioner's compressor is turned off, and the second air guide plate 3 is set to the second air guide angle a2, so that the second air guide plate 3 partially blocks the air outlet of the air conditioner. The third preset threshold corresponding to the current indoor ambient temperature and the third preset threshold corresponding to the current temperature of the evaporator can be determined according to actual needs; this embodiment does not limit this.

[0116] Furthermore, after the air conditioner compressor restarts, the process returns to the step of obtaining the initial temperature parameters. For details, please refer to the content of Embodiment 1, which will not be repeated here.

[0117] In this embodiment, when the current indoor ambient temperature or the current temperature of the evaporator is greater than the third preset threshold, it indicates that the current temperature of the evaporator is too high. To prevent the evaporator from being damaged due to overheating, the air conditioner enters the temperature protection shutdown. Setting the second air guide plate 3 of the air conditioner to the second air guide angle a2 can prevent cold air from blowing directly to the user when the evaporator temperature drops after shutdown. At the same time, after the air conditioner restarts in heating mode, because the second air guide plate 3 is at the second air guide angle a2, the air volume at the air outlet is reduced, which can reduce the drop in evaporator temperature caused by the increase in air volume. This can accelerate the temperature rise rate of the evaporator and refrigerant at the beginning of startup, speed up the rate of increase in indoor ambient temperature, and allow the user to quickly experience hot air.

[0118] In the technical solution provided in this embodiment, when the evaporator temperature of the air conditioner is too high and enters the temperature protection shutdown, the second air guide plate 3 can be turned to the second air guide angle a2 to prevent cold air from blowing directly to the user when the evaporator temperature drops after shutdown. At the same time, after the air conditioner restarts in heating mode, because the second air guide plate 3 is at the second air guide angle a2, the temperature rise rate of the evaporator and refrigerant in the initial stage of start-up can be accelerated, as well as the temperature rise rate of the indoor environment, so that the user can quickly experience hot air.

[0119] To more clearly illustrate the inventive concept of this invention, a specific example is provided below.

[0120] Assuming the initial temperature parameter is the initial indoor ambient temperature corresponding to the air conditioner, denoted by T0; the heating operation parameter is the heating operation duration of the air conditioner, denoted by t; the anti-cold air exit condition is when the heating operation duration t of the air conditioner reaches the reference operation duration, which is different for different initial indoor environments; the first preset threshold is denoted by T1; the second preset threshold is denoted by T2; the first air guide angle is denoted by A1; the second air guide angle is denoted by a1; the third air guide angle is denoted by A2; the fourth air guide angle is denoted by a4; the current indoor ambient temperature is denoted by T3; and the third preset threshold is denoted by T4. The control process is as follows:

[0121] 1. If T2≤T0<T1, the first air guide plate 2 is set to the first air guide angle A1, and the second air guide plate 3 is set to the fourth air guide angle a4. When the heating operation time t of the air conditioner reaches the reference operation time t1, the first air guide plate 2 is set to the third air guide angle A2, and the second air guide plate 3 is set to the fourth air guide angle a4.

[0122] 2. If T0 < T2, the first air guide plate 2 is set to the first air guide angle A1 and the second air guide plate 3 is set to the second air guide angle a1. When the heating operation time t of the air conditioner reaches the reference operation time t2, the first air guide plate 2 is set to the third air guide angle A2 and the second air guide plate 3 is set to the fourth air guide angle a4.

[0123] 3. If T0≥T1, the first air guide plate 2 is set to the third air guide angle A2 and the second air guide plate 3 is set to the second air guide angle a1. When the heating operation time t of the air conditioner reaches the reference operation time t3, the first air guide plate 2 is set to the third air guide angle A2 and the second air guide plate 3 is set to the fourth air guide angle a4.

[0124] If the air conditioner meets the defrosting conditions, the first air guide plate 2 will be set to the first air guide angle A1.

[0125] If T4 < T3, the second air guide plate 3 will be set to the second air guide angle a2.

[0126] Based on experimental test data, the preferred ranges for the setting values ​​of each judgment parameter are as follows:

[0127] T1: 19-20 degrees; T2: 13-15 degrees; t1: 70-120 seconds; t2: 140-230 seconds; t3: 30-60 seconds; a1: 25-80 degrees; A1: 40-80 degrees.
