Description

Technical Field

[0001] The present application relates to the field of air conditioning, and in particular to a control method, a controller, an air conditioner and a readable storage medium for an air conditioner. Background Art

[0002] In winter, due to the cold weather, the refrigerant in the refrigerant pipe of the outdoor unit of the air conditioner is easily frosted. When the temperature is too low, there is even ice, which makes it difficult to start the air conditioner in a low temperature environment, thus affecting the normal operation of the air conditioner. In order to cope with the situation where the air conditioner outdoor unit is frosted or frozen due to cold weather, a heating module is added to the chassis of the air conditioner outdoor unit to heat and defrost or melt ice cubes; when it is detected that the outdoor ambient temperature is lower than the first preset value, the heating module is controlled to heat and defrost all the time, and the heating is not stopped until the outdoor ambient temperature exceeds the second preset value. However, this method requires the heating module to be heated and operated continuously, and it is impossible to start the heating module for heating according to the actual use needs of the user, which increases the energy consumption of the air conditioner.

[0003] In the related art, in order to solve the above problem, the air conditioner's usual start-up time is determined, and preheating is performed before the air conditioner's usual start-up time so that it can quickly enter the working state after receiving the user's power-on command. However, if the user does not start the air conditioner at the usual time, the air conditioner outdoor unit may return to a frosted or frozen state. At this time, if the user turns on the air conditioner, the air conditioner cannot quickly enter the working state, reducing the user experience. Summary of the invention

[0004] The present application aims to solve at least one of the technical problems existing in the prior art.

[0041] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application is further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the characteristics, operations or features described in the specification can be combined in any appropriate manner to form various implementation methods. At the same time, the steps or actions in the method description can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the accompanying drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a necessary sequence, unless otherwise specified that a certain sequence must be followed.

[0042] In the description of this application, "several" means one or more, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0043] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0044] Cold weather can easily cause frost on the refrigerant in the refrigerant pipes of the outdoor unit of the air conditioner. When the temperature is too low, it may even freeze. In severe cases, the outdoor fan impeller may be frozen, increasing the rotational resistance and making it difficult to start the air conditioner in a low temperature environment, thus affecting its normal operation.

[0045] In the related art, in order to solve the problem of frost or ice on the outdoor unit of the air conditioner caused by cold weather, an electric heating pipe is usually added to the chassis of the outdoor unit of the air conditioner to heat and defrost or melt ice cubes to make the air conditioner operate normally; the control method of the air conditioner in the related art is that when the temperature sensor set in the outdoor unit detects that the outdoor ambient temperature is lower than the first preset value, the heating module is controlled to heat and defrost all the time, and the heating is stopped until the outdoor ambient temperature exceeds the second preset value. However, this method requires the heating module to continue heating and running, and it is impossible to start the heating module for heating according to the actual use needs of the user, which makes the energy consumption of the air conditioner higher.

[0046] In the related art, in order to solve the above problem, the air conditioner's usual start-up time is determined, and preheating is performed before the air conditioner's usual start-up time so that it can quickly enter the working state after receiving the user's power-on command. However, if the user does not start the air conditioner at the usual time, the air conditioner outdoor unit may return to a frosted or frozen state. At this time, if the user turns on the air conditioner, the air conditioner cannot quickly enter the working state, reducing the user experience.

[0047] To this end, the embodiments of the present application provide a control method, a controller, an air conditioner and a readable storage medium for an air conditioner, which are beneficial for the air conditioner to operate normally after receiving a power-on command after the usual power-on time, thereby improving the user experience.

[0048] Reference Figure 1 , Figure 1 is a flow chart of a control method of an air conditioner provided in an embodiment of the present application, wherein the air conditioner includes an outdoor unit, and a chassis of the outdoor unit is provided with a heating module; the control method of the air conditioner includes steps S100 to S300, specifically,

[0049] Step S100: determining a common start-up time of the air conditioner;

[0050] Step S200: Obtaining outdoor ambient temperature and current time;

[0051] Step S300: When the outdoor ambient temperature is less than or equal to a first preset temperature and the current time is within a first preset time period after the usual startup time, the heating module is controlled to operate at a first power.

[0052] In some embodiments of the present application, the control method of the air conditioner includes determining the commonly used start-up time of the air conditioner. By determining the commonly used start-up time of the air conditioner, the time period during which the user frequently uses the air conditioner can be known, and the air conditioner can automatically start the heating module for heating according to the commonly used start-up time combined with the outdoor ambient temperature. The outdoor ambient temperature and the current time are obtained. When the outdoor ambient temperature is less than or equal to the first preset temperature and the current time is within the first preset time section after the commonly used start-up time, the heating module is controlled to operate at the first power, which can ensure that when the start-up time of the air conditioner is within the first preset time section of the commonly used start-up time, the heating module operates at the first power to heat and heat up, so that the condensed ice and / or frost of the outdoor unit melts, and ensures that the air conditioner can operate normally when receiving the start-up command, thereby improving the user experience.

[0053] In some embodiments of the present application, the outdoor unit is provided with a temperature sensor for obtaining the outdoor ambient temperature in real time. When the outdoor ambient temperature is less than or equal to the first preset temperature, it is determined whether the current time is the usual start-up time of the air conditioner or is within the first preset time segment after the usual start-up time of the air conditioner. When the current time is within the first preset time segment after the usual start-up time, the heating module is controlled to operate at the first power.

[0054] It should be noted that in some embodiments of the present application, the first power can be set according to the rated power of the heating module and different operating conditions of the air conditioner. The embodiments of the present application do not limit the size of the first power. For example, the first power in the embodiments of the present application can be 1000W, 1200W or 1350W, etc.

[0055] It should be noted that the first preset temperature can be set according to different working conditions of the air conditioner or the outdoor ambient temperature, and the embodiment of the present application does not limit the value of the first preset temperature. For example, the value range of the first preset temperature can be 0 degrees Celsius to 5 degrees Celsius. For example, in some embodiments, the first preset temperature can be 0 degrees Celsius.

[0056] It should be noted that the first preset time segment can be set according to the outdoor ambient temperature, the size of the first power, and different working conditions of the air conditioner, and the embodiment of the present application does not limit the range of the first preset time segment. For example, in some embodiments of the present application, the value range of the first preset time segment can be 10 minutes, 15 minutes, or 20 minutes, for example, the first preset time segment is 15 minutes, then, when the current time is after the usual start-up time of the air conditioner, and the time difference between the current time and the usual start-up time is less than or equal to 15 minutes, if the outdoor ambient temperature is less than or equal to the first preset temperature, the heating module can be controlled to operate the heating module at a low power of the first power to heat up and melt the ice and / or frost condensed on the chassis, thereby ensuring that the air conditioner can operate normally when it receives the start-up command when it is delayed from the usual start-up time of the air conditioner.

[0057] It should be noted that in some embodiments of the present application, the air conditioner outdoor unit is provided with a heating module for heating and heating to remove ice and / or frost to ensure the normal operation of the air conditioner; wherein the heating module is one of an electric heating tube and a metal electric heating rod, and the embodiments of the present application do not limit the type of the heating module.

[0058] In some embodiments of the present application, assuming that after the usual start-up time of the air conditioner is determined, when the outdoor ambient temperature is 0 degrees Celsius, and the current time is after the usual start-up time of the air conditioner, and the time difference between the current time and the usual start-up time is less than or equal to 15 minutes, the heating module can be controlled to operate at 1200W power for heating and heating, so that the ice or frost in the chassis of the outdoor unit can be melted, thereby ensuring the normal operation of the air conditioner; at the same time, it can also avoid the problem of the outdoor wind wheel freezing due to low temperature, resulting in increased resistance to wind wheel rotation. Since the heating module is controlled to run at a low power of 1200W for heating and temperature increase, the energy consumption of the air conditioner can be reduced. At the same time, by determining that the current time is within a preset time period after the usual start-up time, the heating module is controlled to operate so that condensed ice and / or frost on the outdoor unit can melt, ensuring that when the air conditioner receives a start-up command within the first preset time period delayed after the usual start-up time, the air conditioner can operate normally, thereby improving the user experience. At the same time, the heating module can be started to heat the outdoor unit according to the user's usage needs, effectively avoiding continuous heating of the heating module when the outdoor ambient temperature is less than or equal to the first preset temperature, which increases the energy consumption of the air conditioner, thereby achieving energy saving and emission reduction.

[0059] Reference Figure 2 , Figure 2 is a flow chart of another air conditioner control method provided by an embodiment of the present application, including step S200 and step S400. Specifically,

[0060] Step S200: Obtaining outdoor ambient temperature and current time;

[0061] Step S400: When the outdoor ambient temperature is less than or equal to the first preset temperature and the current time is within a second preset time period before the usual startup time, the heating module is controlled to operate at the first power.

[0062] In some embodiments of the present application, a control method for an air conditioner includes, after determining a commonly used start-up time, obtaining an outdoor ambient temperature and a current time, and when the outdoor ambient temperature is less than or equal to a first preset temperature and it is determined that the current time is within a second preset time period before the commonly used start-up time, controlling the heating module to operate at a low power of a first power, and heating the heating module to heat and heat up to melt ice and / or frost condensed on the chassis of the outdoor unit, thereby ensuring that the air conditioner can operate normally when a start-up command is received at the commonly used start-up time, and effectively avoiding continuously heating the heating module when the outdoor ambient temperature is less than or equal to the first preset temperature, thereby increasing the energy consumption of the air conditioner, and being able to start the heating module to heat the outdoor unit in advance of the second preset time according to the actual usage needs of the user, thereby achieving energy saving and emission reduction.

[0063] It should be noted that the second preset time segment can be set according to the outdoor ambient temperature, the size of the first power, and different working conditions of the air conditioner, and the embodiment of the present application does not limit the range of the second preset time segment. For example, in some embodiments of the present application, the value range of the second preset time segment can be 30 minutes, 40 minutes, 50 minutes or 60 minutes, etc. For example, if the second preset time segment is 40 minutes, then when the current time is before the usual start-up time of the air conditioner, and the time difference between the current time and the usual start-up time is less than or equal to 40 minutes, if the outdoor ambient temperature is less than or equal to the first preset temperature, the heating module can be controlled to operate at the first power.

[0064] In some embodiments of the present application, when the outdoor ambient temperature is less than or equal to a first preset temperature and the current time is within a second preset time before the usual start-up time of the air conditioner, the heating module is controlled to operate at a first power. However, when no start-up command of the air conditioner is received within a first time period after the usual start-up time of the air conditioner, the heating module is controlled to continue to operate at a low power of the first power for heating and deicing and / or frost. This ensures that when the air conditioner receives a start-up command outside the first preset time after the usual start-up time, the air conditioner can operate normally.

[0065] It should be noted that, in some embodiments of the present application, for example, the first power may be 1000W. Therefore, the heating module is controlled to operate at 1000W, so that the power consumption of the air conditioner is low, thereby achieving energy conservation and emission reduction.

[0066] Reference Figure 3 , Figure 3is a flow chart of a control method after determining the common start-up time of the air conditioner provided by an embodiment of the present application, including steps S400 to S440. Specifically,

[0067] Step S400: determining the common start-up time of the air conditioner;

[0068] Step S410: in response to receiving a start-up instruction of the air conditioner, starting the air conditioner;

[0069] Step S420: controlling the rotation of the wind wheel of the outdoor fan, and obtaining the rotation resistance of the wind wheel through a preset sensor;

[0070] Step S430: When the rotation resistance is less than the preset resistance, the air conditioner is controlled to operate according to the power-on instruction;

[0071] Step S440: When the rotation resistance is greater than the preset resistance, the wind wheel is controlled to stop rotating.

[0072] In some embodiments of the present application, after determining the common start-up time of the air conditioner, when receiving the receiving instruction of the air conditioner, the air conditioner is started according to the start-up instruction; the wind wheel of the outdoor fan is controlled to rotate left and right at a first angle, and the rotation resistance of the wind wheel is obtained through a preset sensor. The rotation resistance of the wind wheel obtained by the preset sensor and the size of the preset resistance are judged to judge the thawing condition of the ice and / or frost currently condensed on the wind wheel. When the rotation resistance obtained by the preset sensor is less than the preset resistance, it indicates that the ice and / or frost currently attached to the wind wheel is less, and the operating conditions of the air conditioner are met, and the air conditioner is controlled to operate according to the start-up instruction; when the rotation resistance is greater than the preset resistance, it indicates that the ice and / or frost currently attached to the wind wheel is more, and the wind wheel is controlled to stop.

[0073] It should be noted that the first angle can be set according to the outdoor ambient temperature and the mass of the wind wheel, and the embodiment of the present application does not limit the size of the first angle. For example, in some embodiments of the present application, the value range of the first angle can be 1° to 3°, and the wind wheel is controlled to rotate in the left and right directions of 1° to 3° so that the ice and / or frost attached to the wind wheel falls off, thereby reducing the rotation resistance of the wind wheel.

[0074] It should be noted that the preset resistance can be set according to the type of the wind wheel and the outdoor ambient temperature, and the embodiment of the present application does not limit the size of the preset resistance. In some embodiments of the present application, the value range of the preset resistance can be 10N to 15N. For example, the preset resistance in the embodiment of the present application is 10N. When the rotation resistance obtained by the preset sensor is less than 10N, the air conditioner is controlled to run according to the power-on instruction. When the rotation resistance obtained by the preset sensor is greater than 10N, the wind wheel is controlled to stop rotating.

[0075] It should be noted that in some embodiments of the present application, the preset sensor is one of a torque sensor and a pressure sensor. In the embodiments of the present application, a torque sensor is arranged in the outdoor unit, and the rotational resistance of the wind wheel of the outdoor fan is obtained through the torque sensor. The embodiments of the present application do not limit the type of preset sensor.

[0076] In some embodiments of the present application, after determining the usual start-up time of the air conditioner, when the outdoor ambient temperature is less than or equal to the first preset temperature and the current time is within the first preset time segment after the usual start-up time or the current time is within the second preset time segment before the usual start-up time, the heating module is controlled to operate at a low power of the first power to perform heating and deicing and / or frost; when receiving the start-up command of the air conditioner, the air conditioner is started, the wind wheel is controlled to rotate in a direction of 1° to 3°, and the rotation resistance of the wind wheel is recorded. When the rotation resistance of the wind wheel is less than 10N, the air conditioner is controlled to operate according to the start-up command of the air conditioner. When the start-up command is received, the rotation resistance of the wind wheel is first determined, and the air conditioner is controlled to operate only when the rotation resistance meets the preset conditions. Reducing the rotation resistance of the wind wheel can reduce the energy consumption of the air conditioner and avoid motor damage. When the rotational resistance is greater than 10N, it indicates that there is a lot of ice and / or frost attached to the wind wheel, which makes the rotational resistance of the wind wheel too large, causing higher energy consumption during the operation of the air conditioner. At this time, controlling the wind wheel to stop rotating can effectively avoid damage to the motor due to excessive rotational resistance of the wind wheel during the operation of the air conditioner, and at the same time reduce the energy consumption of the air conditioner.

[0077] Reference Figure 4 , Figure 4 is a flow chart of a control method for controlling the operation of a heating module provided in an embodiment of the present application, including steps S450 to S480. Specifically,

[0078] Step S450: controlling the wind wheel to stop rotating;

[0079] Step S460: Controlling the heating module to operate at a third power for a third preset time, where the third power is greater than the first power;

[0080] Step S470: controlling the wind rotor to rotate and obtaining the rotation resistance of the wind rotor;

[0081] Step S480: When the rotation resistance is less than the preset resistance, the air conditioner is controlled to operate according to the power-on instruction.

[0082] In some embodiments of the present application, after receiving the power-on command of the air conditioner, the wind wheel is controlled to rotate and the rotation resistance of the wind wheel is obtained. When the rotation resistance is greater than the preset resistance, it indicates that the current rotation resistance of the wind wheel is too large. In order to avoid damage to the motor, the wind wheel needs to be controlled to stop rotating. After the wind wheel is controlled to stop rotating, the heating module is controlled to operate at a third power for a third preset time, wherein the third power is greater than the first power, so that the heating module operates at the third power for heating and heating to accelerate the melting of ice and / or frost condensed on the chassis of the outdoor unit and ice and / or frost attached to the wind wheel, so as to reduce the rotation resistance of the wind wheel. After the heating module operates at the third power for a third preset time, the rotation resistance of the wind wheel is obtained through a preset sensor. When the rotation resistance is less than the preset resistance, it indicates that the ice and / or frost attached to the wind wheel is less, and the air conditioner is controlled to operate according to the power-on command.

[0083] It should be noted that the third power is greater than the first power, and the third power can be set according to the first power, the outdoor ambient temperature, and the third preset time. The third power is not limited in the embodiments of the present application. For example, in some embodiments of the present application, the third power can be 2800W. By setting the third power to be greater than the first power, the heating efficiency of the heating module can be accelerated, so that the ice and / or frost condensed on the chassis of the outdoor unit and the ice and / or frost attached to the wind wheel can be quickly dissolved, thereby quickly reducing the rotation resistance of the wind wheel and ensuring the normal operation of the air conditioner.

[0084] It should be noted that the third preset time can be set according to the third power and the outdoor ambient temperature, and the embodiment of the present application does not limit the range of the third preset time. For example, in some embodiments of the present application, the value range of the third preset time can be 3 minutes to 6 minutes, for example, the third preset time is 5 minutes, and by controlling the heating module to run at the third power for 5 minutes, the heating efficiency can be improved, so that the ice and / or frost condensed on the chassis of the outdoor unit and the ice and / or frost attached to the wind wheel can be quickly dissolved.

[0085] Reference Figure 5 , Figure 5 is a flow chart of a method for determining a common startup time of an air conditioner provided by an embodiment of the present application, comprising step S110 and step S120. Specifically,

[0086] Step S110: recording a plurality of start-up times of the air conditioner, removing the maximum value and the minimum value of the first number of start-up times recorded, and obtaining a second number of start-up times;

[0087] Step S120: Determine the common startup time of the air conditioner according to the second number of startup times.

[0088] In some embodiments of the present application, the method for determining the commonly used startup time of the air conditioner includes recording multiple startup times of the air conditioner, removing the maximum value and the minimum value of the first number of startup times recorded, obtaining the second number of startup times, and performing data processing on the second number of startup times to obtain the commonly used startup time of the air conditioner. By removing the maximum value and the minimum value of the first number of startup times recorded, the accuracy and reliability of the predicted commonly used startup time can be improved, so that the air conditioner can accurately start the heating module according to the commonly used startup time of the air conditioner to heat the outdoor unit, avoiding unnecessary energy consumption caused by starting the heating module too early for heating, thereby achieving energy saving and emission reduction.

[0089] It should be noted that, in some embodiments of the present application, determining the commonly used power-on time of the air conditioner based on the second number of startup times includes obtaining the commonly used power-on time by averaging the second number of startup times; determining the commonly used power-on time of the air conditioner based on the second number of startup times also includes obtaining the commonly used power-on time by performing mode processing on the second number of startup times to obtain the commonly used power-on time, obtaining the median processing on the second number of startup times to obtain the commonly used power-on time, and obtaining the variance processing on the second number of startup times to obtain the commonly used power-on time. The embodiments of the present application do not limit the method for obtaining the commonly used power-on time based on the second number of startup times, and those skilled in the art can choose an appropriate method to determine the commonly used power-on time of the air conditioner according to actual conditions.

[0090] It should be noted that in some embodiments of the present application, the first number is 15, and the second number of air conditioner start-up times is obtained by recording 15 air conditioner start-up times and removing the maximum and minimum values ​​of the 15 air conditioner start-up times, wherein the second number is 13, and the 13 air conditioner start-up times are averaged to obtain the common start-up time. By recording the start-up time of the air conditioner multiple times, the accuracy and reliability of determining the common start-up time of the air conditioner are improved, so as to accurately control the heating module to start heating and heating in the first preset time section before the common start-up time or in the second preset time section after the common start-up time to perform deicing or defrosting, thereby ensuring the normal operation of the air conditioner.

[0091] Reference Figure 6 , Figure 6 is a flowchart of a method for recording multiple startup times of an air conditioner provided by an embodiment of the present application, including steps S500 to S510. Specifically,

[0092] Step S500: when receiving the start-up command of the air conditioner, controlling the rotation of the wind wheel of the outdoor fan, and obtaining the rotation resistance of the wind wheel through a preset sensor;

[0093] Step S510: When the rotation resistance is less than the preset resistance, the time corresponding to the receipt of the power-on instruction is recorded as one of the start-up times of the air conditioner.

[0094] In some embodiments of the present application, before determining the commonly used start-up time of the air conditioner, when a start-up command of the air conditioner is received, the wind wheel of the outdoor fan is controlled to rotate to the left and right at a second angle, and the rotation resistance of the wind wheel is obtained through a preset sensor; when the obtained rotation resistance is less than the preset resistance, that is, the wind wheel can rotate normally, the time corresponding to the received start-up command of the air conditioner is used as one of the start-up times of the air conditioner, and the commonly used start-up time is determined based on multiple start-up times.

[0095] It should be noted that, in some embodiments of the present application, when the rotational resistance of the wind wheel is less than the preset resistance, it indicates that the ice and / or frost currently frozen on the wind wheel is reduced, and it can be known that the heating module is continuously heating to remove ice and / or frost, so that the ice and / or frost on the wind wheel melts, thereby reducing the rotational resistance of the wind wheel. When the rotational resistance of the wind wheel is less than the preset resistance, it is ensured that the wind wheel can rotate normally when receiving the power-on command of the air conditioner, and the time corresponding to the received power-on command of the air conditioner is recorded as the start-up time of the air conditioner.

[0096] It should be noted that the second angle can be set according to the outdoor ambient temperature and the mass of the wind wheel, and the embodiment of the present application does not limit the size of the second angle. For example, in some embodiments of the present application, the value range of the second angle can be 1° to 3°. By controlling the wind wheel to rotate at about 1° to 3°, the ice or frost frozen on the wind wheel can be thrown off, so that the wind wheel can rotate normally.

[0097] Reference Figure 7 , Figure 7 is a flow chart of a control method before determining a common start-up time of an air conditioner provided by an embodiment of the present application, including steps 600 to S610, specifically

[0098] Step S600: When the outdoor ambient temperature is less than or equal to the first preset temperature, the heating module is controlled to operate at a second power, the second power being greater than the first power;

[0099] Step S610: Determine the common start-up time of the air conditioner.

[0100] In some embodiments of the present application, before determining the commonly used startup time of the air conditioner, when the outdoor ambient temperature is less than or equal to the first preset temperature, the heating module is controlled to operate at the second power, and the commonly used startup time of the air conditioner is determined according to the startup time of multiple recorded air conditioners. By controlling the heating module to operate at the second power before determining the commonly used startup time of the air conditioner and when the outdoor ambient temperature is less than or equal to the first preset temperature, since the second power is greater than the first power, the heating efficiency of the heating module is faster, so that the ice or frost condensed on the chassis or the outdoor wind wheel due to the cold weather can be quickly melted, so that the rotation resistance of the wind wheel is reduced, so that when the air conditioner receives the startup instruction, the air conditioner can be quickly started to run, the accuracy of the startup time of the air conditioner is improved, and the commonly used startup time can be accurately determined according to the startup time of the air conditioner, so that the heating module can be started for heating according to the actual use needs of the user, and energy saving and emission reduction can be achieved.

[0101] It should be noted that the second power can be set according to the first power and the outdoor ambient temperature, and the embodiment of the present application does not limit the second power. For example, in some embodiments of the present application, the second power can be 3000 W. Since the second power is higher than the first power, the heating efficiency of the heating module is faster, so that the melting rate of the frost or ice condensed on the chassis or the wind wheel of the outdoor unit is faster, ensuring the normal operation of the air conditioner.

[0102] Reference Figure 8 , Figure 8 is a flowchart of another control method after determining the common start-up time of the air conditioner provided by an embodiment of the present application, including steps S700 to S730. Specifically,

[0103] Step S700: recording the start-up time of the air conditioner, and determining a common start-up time according to a plurality of start-up times;

[0104] Step S710: When a power-on command of the air conditioner is received and the current time is not within a first preset time segment after the usual power-on time and not within a second preset time segment before the usual power-on time, the wind wheel of the outdoor fan is controlled to rotate, and the rotation resistance of the wind wheel is obtained through a preset sensor;

[0105] Step S720: when the rotation resistance is greater than the preset resistance, controlling the heating module to operate at the third power for a fourth preset time; controlling the wind wheel to rotate again and obtaining the rotation resistance of the wind wheel;

[0106] Step S730: When the rotation resistance is less than the preset resistance, the air conditioner is controlled to operate according to the power-on instruction.

[0107] In some embodiments of the present application, after determining the commonly used startup time based on multiple start-up times of the air conditioner, when a startup command of the air conditioner is received, but the current time is not within a first preset time segment after the commonly used startup time and the current time is not within a second preset time segment before the commonly used startup time, the rotation resistance of the wind wheel is obtained and judged against the preset resistance. When the rotation resistance is greater than the preset resistance, it indicates that the current rotation resistance of the wind wheel is too large and there is too much ice and / or frost attached to the wind wheel. The heating module is controlled to operate at a third power for a fourth preset time to heat the room so as to speed up the melting rate of the ice and / or frost, thereby reducing the rotation resistance of the wind wheel. After the heating module has operated at the third power for a fourth preset time, the wind wheel is controlled to rotate again and the rotation resistance of the wind wheel is obtained. When the rotation resistance of the wind wheel is less than the preset resistance, the operation of the air conditioner is controlled according to the startup command. This can reduce the energy consumption of the air conditioner and achieve energy conservation and emission reduction. At the same time, it can also effectively avoid damage to the motor due to excessive rotation resistance of the wind wheel, thereby ensuring the normal operation of the air conditioner.

[0108] It should be noted that the fourth preset time can be set according to the size of the third power and the rotational resistance of the wind wheel, and the embodiment of the present application does not limit the range of the fourth preset time. In some embodiments of the present application, the value range of the fourth preset time can be 3 minutes to 6 minutes. For example, in the embodiment of the present application, the third power can be 2800W and the fourth preset time is 5 minutes. By controlling the heating module to heat continuously at 2800W for 5 minutes, the ice and / or frost attached to the wind wheel can be quickly dissolved, thereby quickly reducing the rotational resistance of the wind wheel.

[0109] In some embodiments of the application, the control method of the air conditioner includes recording the actual use of the air conditioner when the outdoor ambient temperature is lower than the preset temperature of the outdoor unit of the air conditioner for more than 15 times, obtaining the time period when the user uses the air conditioner, and determining the common start-up time of the air conditioner according to the start-up time of the air conditioner for multiple times. By determining the common start-up time of the air conditioner, the time period during which the user often uses the air conditioner can be known, and the air conditioner can automatically start the heating module for heating according to the common start-up time combined with the outdoor ambient temperature. For example, after determining the common start-up time, when it is detected that the outdoor ambient temperature is lower than the preset temperature of the outdoor unit of the air conditioner, the current time is before the common start-up time of the air conditioner and the time difference between the current time and the common start-up time is less than 40 minutes, and the current time is after the common start-up time of the air conditioner and the time difference between the current time and the common start-up time is less than 15 minutes, the electric heating pipe of the chassis can be turned on with a lower first power to heat for deicing and / or frost, and there is no need to start the electric heating pipe for continuous heating when the outdoor ambient temperature is lower than the preset temperature of the outdoor unit of the air conditioner, so as to increase the energy consumption of the air conditioner; because the first power is relatively low, the air conditioner has low energy consumption when the electric heating pipe is heated, thereby achieving energy saving and emission reduction.

[0110] If the power-on command of the air conditioner is not received during this time period, the electric heating tube is not turned off, and the electric heating tube is still operated at a lower first power; if the power-on command of the air conditioner is received during this time period, the wind wheel is controlled to rotate at about 1° to 3°, and when the rotation resistance of the wind wheel outside the air conditioner is less than or equal to the maximum preset rotation resistance, the air conditioner is controlled to operate according to the power-on command; when the rotation resistance of the wind wheel outside the air conditioner is greater than the maximum preset rotation resistance, the air conditioner enters an abnormal mode. Based on the wind wheel material, the maximum preset rotation resistance of the embodiment of the present application is set to 10N. When the air conditioner receives the power-on command of the air conditioner in the abnormal mode, and the rotation resistance of the wind wheel is greater than the maximum rotation resistance, the electric heating tube of the chassis is operated at a higher third power at this time, which can quickly make the rotation resistance of the wind wheel outside the air conditioner less than the maximum preset rotation resistance within 5 minutes. The control method of the air conditioner provided in the embodiment of the present application can start the electric heating tube under the premise of meeting the actual use needs of the user, and can achieve energy conservation and emission reduction. The air conditioner is controlled to operate according to the power-on instruction only when the rotation resistance of the outdoor wind wheel is less than the maximum rotation resistance, so that the rotation resistance of the wind wheel is smaller when the air conditioner is running, further reducing the energy consumption of the air conditioner, and at the same time can effectively avoid damage to the motor due to excessive rotation resistance of the wind wheel.
