Description

Technical Field

[0001] This application relates to the field of air conditioning, and in particular to a method, apparatus, medium, and air supply appliance for controlling the air sweeping of an air supply appliance. Background Technology

[0002] With technological advancements and rising living standards, air-conditioned appliances have become indispensable household appliances. For example, in air conditioners, the motor is the core component, driving the fan blades to exchange heat and cold energy.

[0003] Most modern air conditioners have a swing function. When the fan motor is running and the air conditioner's swing vane is oscillating, the change in air resistance caused by the rotation of the vane leads to changes in the static pressure inside the air conditioner. The motor speed changes accordingly with this static pressure change, resulting in motor oscillation, unstable power, and unstable speed. This is especially true for air-supply appliances with left and right swing functions, where the motor oscillation reaches its maximum intensity when the upper and lower air guide vanes and left and right grilles simultaneously swing to their most extreme positions. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, this application provides a method, device, medium and air supply appliance for controlling the air sweeping of an air supply appliance, so as to solve the problems that the motor is prone to oscillation, unstable power and unstable speed when the existing air supply appliance is sweeping.

[0005] The technical solution adopted by this application to solve its technical problem is:

[0006] Firstly, a method for controlling the swing of air in a household appliance is provided, including:

[0007] Obtain the target parameters of the motor used for sweeping under the same operating state, wherein the operating state includes the sweeping mode and the fan speed, and the target parameters include either the input power or the actual speed.

[0008] If the number of times the target parameter is outside the preset target range within the preset time period is greater than the preset number, then the upper and lower air guide plates and / or the left and right grilles will be adjusted according to the air sweeping mode.

[0009] Furthermore, the sweeping mode includes simultaneously activating vertical sweeping and horizontal sweeping, and adjusting the vertical air guides and / or the left and right grilles according to the sweeping mode includes:

[0010] Adjust the up-and-down sweeping cycle and the left-and-right sweeping cycle to be the same, and control the phase difference between the up-and-down air guide plates and the left-and-right grilles to be one-quarter of a cycle. The phase is the phase of the position-time curve of the up-and-down air guide plates and the left-and-right grilles.

[0011] Furthermore, the sweeping mode includes activating only the vertical sweeping mode, and adjusting the vertical air guides and / or the left and right grilles according to the sweeping mode includes:

[0012] Reduce the angular velocity of the upper and lower air guide plates.

[0013] Furthermore, the air-sweeping mode includes activating only left and right air sweeping, and the adjustment of the upper and lower air guides and / or the left and right grilles according to the air-sweeping mode includes:

[0014] Reduce the angular velocity of the left and right grilles.

[0015] Furthermore, the target parameter not falling within the preset target range includes:

[0016] The absolute value of the difference between the target parameter and the preset target parameter at the current fan speed is greater than a threshold, where the threshold is the preset target parameter multiplied by a preset ratio.

[0017] Furthermore, it also includes:

[0018] If the number of times the target parameter is outside the preset target range within the preset time period is less than or equal to the preset number, then the period and angular velocity of the upper and lower air guide plates and / or the left and right grilles are kept unchanged.

[0019] Furthermore, obtaining the target parameters of the motor used for sweeping under the same operating state includes:

[0020] When the air-blowing appliance starts its sweeping operation, the target parameters of the motor used for sweeping are obtained under the same operating conditions.

[0021] Secondly, a swing control device for air-supplying household appliances is provided, comprising:

[0022] The parameter acquisition module is used to acquire the target parameters of the motor used for sweeping under the same operating state. The operating state includes the sweeping mode and the fan speed. The target parameters include either the input power or the actual speed.

[0023] The air-sweeping adjustment module is used to adjust the upper and lower air guide plates and / or the left and right grilles according to the air-sweeping mode if the number of times the target parameter is not in the preset target range within a preset time period is greater than a preset number.

[0024] Thirdly, a computer-readable storage medium is provided, comprising:

[0025] At least one processor and at least one memory;

[0026] The memory is used to store the executable instructions of the processor;

[0027] When the executable command is executed, the processor is used to perform the method described above.

[0028] Fourthly, a ventilation appliance is provided, which applies the above-mentioned method.

[0029] Beneficial effects:

[0030] This application provides a method, device, medium, and appliance for controlling the swing of a blower appliance. The swing control method includes: acquiring target parameters of the motor used for swinging under the same swing mode and fan speed; if the number of times the target parameters are outside the preset target range within a preset time period exceeds a preset number, it is determined that the motor oscillates severely. Therefore, it is necessary to adjust the upper and lower air guides and / or the left and right grilles according to the swing mode. The target parameters are the motor's input power and actual speed, because both the motor's input power and actual speed change when the motor oscillates, so selecting either one is sufficient to accurately determine whether the motor oscillates severely. This allows for the reduction of wind resistance changes by controlling the upper and lower air guides and / or the left and right grilles when the blower appliance is swinging and the motor oscillates severely, maintaining a stable airflow while reducing the degree of motor oscillation, thus stabilizing the motor power and speed. Attached Figure Description

[0031] To more clearly illustrate the technical solutions in the embodiments of this application or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0032] Figure 1 This is a flowchart of a method for controlling the airflow of a household appliance according to an embodiment of this application;

[0033] Figure 2 This application provides a position-velocity curve for vertical and horizontal air sweeping.

[0034] Figure 3 This is a schematic diagram of the structure of a wind-sweeping control device for a household appliance provided in an embodiment of this application. Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be described in detail below with reference to the accompanying drawings and embodiments. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. Based on the embodiments of this application, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0036] This application includes, but is not limited to, air conditioners, multi-split air conditioners, central air conditioners, and dehumidifiers. Taking an air conditioner as an example, in existing air conditioners, the angle of the rotating upper and lower air guides or left and right grilles changes, causing variations in air resistance. To ensure that the airflow remains constant regardless of the angle of the upper and lower air guides or left and right grilles, the motor used for air sweeping needs to increase its speed or input power when the air resistance increases. Conversely, when the air resistance decreases, the motor needs to decrease its speed or input power. Within a single air sweeping cycle, the motor speed and input power fluctuate significantly. Frequent changes in motor speed and input power within a short period can easily lead to severe motor wear. Currently, the upper and lower sweeping and left and right sweeping speeds are fixed. Especially since the control of upper and lower sweeping and left and right sweeping is independent, when the upper and lower air guides and left and right grilles simultaneously sweep to their most extreme positions, the motor oscillation reaches its maximum intensity.

[0037] To address the aforementioned issues, this application optimizes the airflow pattern of the upper and lower air guide plates and the left and right grilles, ensuring stable airflow while reducing motor oscillation amplitude, minimizing speed and power fluctuations, and improving air conditioning comfort.

[0038] Reference Figure 1 This application provides a method for controlling the swing of an air-supplying household appliance, including:

[0039] S11: Obtain the target parameters of the motor used for sweeping under the same operating state, wherein the operating state includes the sweeping mode and the fan speed, and the target parameters include either the input power or the actual speed.

[0040] It is understandable that when obtaining target parameters, one is the target parameter in the left-right swing mode and the other is the target parameter in the up-down swing mode. Since the target parameter settings are different in the left-right swing mode and the up-down swing mode, the same target parameter value may be in the preset target range in the left-right swing mode but not in the preset target range in the up-down swing mode. Therefore, when actually obtaining target parameters, it is necessary to ensure that the target parameters obtained are in the same swing mode.

[0041] Furthermore, even under the same sweeping mode, the target parameters of the motor are different when the fan speed is different. Therefore, under the same operating conditions, it is necessary to ensure the same sweeping mode and the same fan speed.

[0042] In some embodiments, the target parameters of the motor differ between air conditioning cooling and heating modes, even under the same air swing mode and fan speed. Therefore, in some embodiments, it is also necessary to ensure that the air conditioner is operating in the same mode under the same operating conditions.

[0043] When a motor oscillates, both its input power and speed will change. Therefore, the input power and actual speed can be used to determine whether the motor is oscillating or whether the upper and lower air guides and left and right grilles need to be adjusted.

[0044] Since power is the product of voltage and current, or the ratio of the square of voltage to resistance, or the product of the square of current and resistance, the target parameters can be obtained by using voltage and current alone when the resistance remains constant.

[0045] As an optional implementation of this application, when the air conditioner activates its swing function, the target parameters of the motor used for swinging are acquired under the same operating conditions. That is, the target parameters are only acquired after the air conditioner's swing function is detected. When the air conditioner's swing function is not activated, the target parameters are not acquired. Monitoring the activation of the air conditioner's swing function can be achieved by detecting whether a user command to activate the swing function is received, or by monitoring whether the upper and lower air guides and left and right grilles move after the unit has been running for a period of time.

[0046] S12: If the number of times the target parameter is outside the preset target range within the preset time period is greater than the preset number, then adjust the upper and lower air guide plates and / or the left and right grilles according to the air sweeping mode.

[0047] First, it should be noted that the preset duration needs to be greater than the cycle of vertical or horizontal air sweeping, and to ensure sufficient data acquisition, it is generally n times the cycle of vertical or horizontal air sweeping, where n is greater than or equal to 10. Of course, the specific preset duration should be set according to actual needs. Similarly, the preset number of times should be set according to actual needs.

[0048] Specifically, the air-sweeping mode includes simultaneously activating vertical air-sweeping and horizontal air-sweeping, and adjusting the vertical air guide plates and / or the horizontal grilles according to the air-sweeping mode includes:

[0049] The vertical and horizontal sweeping cycles are adjusted to be the same, and the phases of the vertical and horizontal guide vanes and the left and right grilles are controlled to differ by a quarter of a cycle. The phase is the phase of the position-time curve of the vertical and horizontal guide vanes and the left and right grilles. The position-time curves of the vertical and horizontal guide vanes and the left and right grilles are as follows: Figure 2As shown. When the vertical sweeping cycle and the horizontal sweeping cycle are the same and their phases differ by a quarter cycle, the left and right grilles sweep to the leftmost or rightmost end when the vertical guide vanes are centered, and the vertical guide vanes sweep to the topmost or bottommost end when the left and right grilles are centered. This prevents the vertical guide vanes and the left and right grilles from being at extreme angles simultaneously, avoiding excessive motor oscillation. Furthermore, the phase difference of a quarter cycle between the vertical guide vanes and the left and right grilles can be either the phase of the vertical guide vanes minus the phase of the left and right grilles equals a quarter cycle, or the phase of the left and right grilles minus the phase of the vertical guide vanes equals a quarter cycle. It is understood that although this application only provides a quarter cycle, in practice, any difference of a quarter cycle between the phases of the vertical guide vanes and the left and right grilles is an odd multiple of a quarter cycle will satisfy the requirements of this application.

[0050] In another embodiment, the sweeping mode includes activating only vertical sweeping. Adjusting the vertical and horizontal air guides and / or the left and right grilles according to the sweeping mode includes reducing the angular velocity of the vertical and horizontal air guides. When the angular velocity of the vertical and horizontal air guides is reduced, the number of times the angles of the vertical and horizontal air guides are at their extremes (top or bottom) within a preset time period will decrease, thus reducing the number of times the target parameter is outside the preset target range. This is because the number of times the target parameter is outside the preset target range generally occurs when the angles of the vertical and horizontal air guides are at their extremes.

[0051] In another implementation, the sweeping mode includes activating only left and right sweeping. Adjusting the upper and lower air guides and / or the left and right grilles according to the sweeping mode includes reducing the angular velocity of the left and right grilles. When the angular velocity of the left and right grilles is reduced, the number of times the left and right grille angles are at their extremes (rightmost or leftmost) within a preset time period will decrease, thus reducing the number of times the target parameter is outside the preset target range. This is because the number of times the target parameter is outside the preset target range generally occurs when the left and right grille angles are at their extremes.

[0052] Furthermore, if the number of times the target parameter is outside the preset target range within a preset time period is less than or equal to the preset number, then the period and angular velocity of the upper and lower air guides, and / or the left and right grilles, remain unchanged. When the number of times the target parameter is outside the preset target range within a preset time period is less than or equal to the preset number, it indicates that the motor does not oscillate (i.e., the number is 0), or that although the motor oscillates, it does not affect actual use and causes minimal wear and tear on components (the number is not 0).

[0053] It should be noted that the target parameter is not within the preset target range, including:

[0054] The absolute value of the difference between the target parameter and the preset target parameter at the current fan speed is greater than a threshold, where the threshold is the preset target parameter multiplied by a preset ratio. The preset target parameter and preset ratio are set according to actual needs. This application uses the preset target parameter multiplied by a preset ratio as the threshold, which can meet the requirement of accurate judgment even when the preset target parameter is large. Of course, for simplicity of calculation, this application can also use a fixed value as the threshold.

[0055] The air-sweeping control method for air-supplying appliances provided in this application obtains the target parameters of the motor used for sweeping under the same sweeping mode and the same fan speed. If the number of times the target parameters are outside the preset target range within a preset time period exceeds a preset number, it is determined that the motor oscillates severely. Therefore, it is necessary to adjust the upper and lower air guides and / or the left and right grilles according to the sweeping mode. The target parameters are the motor's input power and actual speed. Because both the motor's input power and actual speed change when the motor oscillates, selecting either one is sufficient to accurately determine whether the motor oscillates severely. This allows for the reduction of air resistance changes by controlling the upper and lower air guides and / or the left and right grilles when the air conditioner is sweeping and the motor oscillates severely, thereby maintaining a stable airflow while reducing the degree of motor oscillation, resulting in stable motor power and speed.

[0056] Based on the same inventive concept, this application also provides a swing control device for air-supplying household appliances, such as... Figure 3 As shown, it includes:

[0057] The parameter acquisition module 31 is used to acquire the target parameters of the motor used for sweeping under the same operating state. The operating state includes the sweeping mode and the fan speed. The target parameters include either the input power or the actual speed.

[0058] It is understandable that when acquiring target parameters, one is the target parameter in the left-right swing mode and the other is the target parameter in the up-down swing mode. Since the target parameter settings are different in the left-right swing mode and the up-down swing mode, the same target parameter value may be in the preset target range in the left-right swing mode but not in the preset target range in the up-down swing mode. Therefore, when actually acquiring target parameters, it is necessary to ensure that the parameter acquisition module 31 acquires the target parameter in the same swing mode.

[0059] Furthermore, even under the same sweeping mode, the target parameters of the motor are different when the fan speed is different. Therefore, under the same operating conditions, it is necessary to ensure that the same sweeping mode and the same fan speed are maintained.

[0060] In some embodiments, the target parameters of the motor differ between air conditioning cooling and heating modes, even under the same air swing mode and fan speed. Therefore, in some embodiments, it is also necessary to ensure that the air conditioner is operating in the same mode under the same operating conditions.

[0061] When a motor oscillates, both its input power and speed will change. Therefore, the input power and actual speed can be used to determine whether the motor is oscillating or whether the upper and lower air guides and left and right grilles need to be adjusted.

[0062] Since power is the product of voltage and current, or the ratio of the square of voltage to resistance, or the product of the square of current and resistance, the target parameters can be obtained by using voltage and current alone when the resistance remains constant.

[0063] As an optional implementation of this application, when the air conditioner activates its swing function, the parameter acquisition module 31 acquires the target parameters of the motor used for swing operation under the same operating state. That is, the parameter acquisition module 31 only acquires the target parameters after detecting that the air conditioner has activated its swing function. When the air conditioner is not activating its swing function, the parameter acquisition module 31 does not acquire the target parameters. Monitoring the activation of the air conditioner's swing function can be done by detecting whether a user command to activate the swing function is received, or by monitoring whether the upper and lower air guide plates and left and right grilles move after the unit has been running for a period of time.

[0064] The air-sweeping adjustment module 32 is used to adjust the upper and lower air guide plates and / or the left and right grilles according to the air-sweeping mode if the number of times the target parameter is not in the preset target range within a preset time period is greater than a preset number.

[0065] First, it should be noted that the preset duration needs to be greater than the cycle of vertical or horizontal air sweeping, and to ensure sufficient data acquisition, it is generally n times the cycle of vertical or horizontal air sweeping, where n is greater than or equal to 10. Of course, the specific preset duration should be set according to actual needs. Similarly, the preset number of times should be set according to actual needs.

[0066] Specifically, the air-sweeping mode includes simultaneously activating vertical air-sweeping and horizontal air-sweeping, and adjusting the vertical air guide plates and / or the horizontal grilles according to the air-sweeping mode includes:

[0067] The air-sweeping adjustment module 32 adjusts the vertical sweeping cycle and the horizontal sweeping cycle to be the same, and controls the phase difference between the vertical guide vanes and the left and right grilles to be one-quarter of a cycle. The phase is the phase of the position-time curve of the vertical guide vanes and the left and right grilles. When the vertical and horizontal sweeping cycles are the same and the phase difference is one-quarter of a cycle, when the vertical guide vanes are centered, the left and right grilles sweep to the leftmost or rightmost end; when the left and right grilles are centered, the vertical guide vanes sweep to the topmost or bottommost end. This prevents the vertical guide vanes and the left and right grilles from being at extreme angles simultaneously, avoiding excessive motor oscillation. Furthermore, the one-quarter-cycle phase difference between the vertical guide vanes and the left and right grilles can be either the phase of the vertical guide vanes minus the phase of the left and right grilles equals one-quarter of a cycle, or the phase of the left and right grilles minus the phase of the vertical guide vanes equals one-quarter of a cycle. It is understood that although this application only provides one-quarter of a cycle, in practice, any phase difference between the vertical guide vanes and the left and right grilles that is an odd multiple of one-quarter of a cycle satisfies the requirements of this application.

[0068] In another embodiment, the sweeping mode includes only activating vertical sweeping. Adjusting the vertical and horizontal air guides and / or the left and right grilles according to the sweeping mode includes: the sweeping adjustment module 32 reducing the angular velocity of the vertical and horizontal air guides. When the angular velocity of the vertical and horizontal air guides is reduced, the number of times the angles of the vertical and horizontal air guides are at their extremes (top or bottom) within a preset time period will decrease, thus reducing the number of times the target parameter is outside the preset target range. This is because the number of times the target parameter is outside the preset target range generally occurs when the angles of the vertical and horizontal air guides are at their extremes.

[0069] In another implementation, the sweeping mode includes only activating left and right sweeping. The adjustment of the upper and lower air guides and / or the left and right grilles according to the sweeping mode includes: the sweeping adjustment module 32 reducing the angular velocity of the left and right grilles. When the angular velocity of the left and right grilles is reduced, the number of times the left and right grille angles are at their extremes (rightmost or leftmost) within a preset time period will decrease, thus reducing the number of times the target parameter is outside the preset target range. This is because the number of times the target parameter is outside the preset target range generally occurs when the left and right grille angles are at their extremes.

[0070] Furthermore, if the number of times the target parameter is outside the preset target range within a preset time period is less than or equal to the preset number, the air-sweeping adjustment module 32 controls the period and angular velocity of the upper and lower air guide plates, and / or the left and right grilles, to remain unchanged. When the number of times the target parameter is outside the preset target range within a preset time period is less than or equal to the preset number, it indicates that the motor does not oscillate (i.e., the number is 0), or that although the motor oscillates, it does not affect actual use and causes minimal wear and tear on components (the number is not 0).

[0071] It should be noted that the target parameter is not within the preset target range, including:

[0072] The absolute value of the difference between the target parameter and the preset target parameter at the current fan speed is greater than a threshold, where the threshold is the preset target parameter multiplied by a preset ratio. The preset target parameter and preset ratio are set according to actual needs. This application uses the preset target parameter multiplied by a preset ratio as the threshold, which can meet the requirement of accurate judgment even when the preset target parameter is large. Of course, for simplicity of calculation, this application can also use a fixed value as the threshold.

[0073] The air-sweeping control device for air-supplying appliances provided in this application acquires the target parameters of the motor used for sweeping under the same sweeping mode and fan speed in the parameter acquisition module. If the number of times the target parameters are outside the preset target range within a preset time period exceeds a preset number, the sweeping adjustment module determines that the motor oscillates severely. Therefore, it is necessary to adjust the upper and lower air guides and / or the left and right grilles according to the sweeping mode. The target parameters are the motor's input power and actual speed. Because both the motor's input power and actual speed change when the motor oscillates, selecting either one is sufficient to accurately determine whether the motor oscillates severely. This allows for the reduction of air resistance changes by controlling the upper and lower air guides and / or the left and right grilles when the air conditioner is sweeping and the motor oscillates severely, thereby maintaining a stable air supply while reducing the degree of motor oscillation, resulting in stable motor power and speed.

[0074] Based on the same inventive concept, this application provides a computer-readable storage medium, comprising:

[0075] At least one processor and at least one memory;

[0076] The memory is used to store the executable instructions of the processor;

[0077] When the executable command is executed, the processor is used to execute the air supply appliance sweep control method provided in the above embodiments.

[0078] The computer-readable storage medium provided in this application embodiment stores executable instructions for a processor. When the executable instructions are executed, the processor can obtain the target parameters of the motor used for sweeping under the same sweeping mode and the same fan speed. If the number of times the target parameters are outside the preset target range within a preset time period is greater than a preset number, it is determined that the motor oscillation is severe. Therefore, it is necessary to adjust the upper and lower air guides and / or the left and right grilles according to the sweeping mode. The target parameters are the motor's input power and actual speed. Because both the motor's input power and actual speed change when the motor oscillates, selecting either one is sufficient to accurately determine whether the motor oscillates severely. This allows for the reduction of wind resistance changes by controlling the upper and lower air guides and / or the left and right grilles when the air conditioner is sweeping and the motor oscillates severely, thereby maintaining a stable airflow while reducing the degree of motor oscillation, resulting in stable motor power and speed.

[0079] Based on the same concept, this application also provides a ventilation appliance that applies the ventilation appliance swing control method provided in the above embodiments. The ventilation appliances in this application include, but are not limited to, air conditioners, multi-split air conditioners, central air conditioners, and dehumidifiers.

[0080] The air-purifying appliance provided in this application can acquire the target parameters of the motor used for air purging under the same purging mode and fan speed. If the number of times the target parameters are outside the preset target range within a preset time period exceeds a preset number, it is determined that the motor oscillates severely. Therefore, it is necessary to adjust the upper and lower air guides and / or the left and right grilles according to the purging mode. The target parameters are the motor's input power and actual speed. Because both the motor's input power and actual speed change when the motor oscillates, selecting either one is sufficient to accurately determine whether the motor oscillates severely. This allows for the reduction of wind resistance changes by controlling the upper and lower air guides and / or the left and right grilles when the air conditioner is purging and the motor oscillates severely, thereby maintaining a stable airflow while reducing the degree of motor oscillation, resulting in stable motor power and speed.
