Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a method, device, air conditioner and storage medium for controlling the air volume of an air conditioner. Background Art

[0002] During air conditioning operation, the rotation of the cross-flow fan creates positive and negative pressure within the air duct, drawing air in through the air inlet, through the indoor heat exchanger, and out the outlet. The air passing through the indoor heat exchanger exchanges energy there, achieving both cooling and heating effects. Therefore, the airflow rate of an air conditioner determines its efficiency. In actual use, reduced airflow can occur, leading to lower airflow efficiency.

[0003] Related technology discloses a self-compensation control method for air conditioning air volume, comprising the following steps: Step 1, obtaining the current degree of dirtiness and blockage of the air conditioning dust filter; Step 2, obtaining the fan speed compensation corresponding to the current degree of dirtiness and blockage according to a pre-established fan speed compensation calculation formula; Step 3, obtaining the target speed of the fan according to the fan speed compensation; Step 4, controlling the fan operation according to the target speed of the fan.

[0004] During the implementation of the embodiments of the present disclosure, it was found that at least the following problems exist in the related art:

[0005] Simply compensating the fan speed based on the degree of filter dirtiness will not accurately increase the air volume.

[0029] Combine Figure 1 As shown, the embodiment of the present disclosure provides a method for controlling the air volume of an air conditioner, comprising:

[0030] S101: The air conditioner obtains its actual air outlet speed.

[0031] S102: When the actual air outlet speed of the air conditioner is lower than the theoretical air outlet speed, the motor speed of the fan is obtained.

[0032] S103: The air conditioner determines a target adjustment parameter based on the matching condition between the motor speed and the current wind speed.

[0033] S104, the air conditioner adjusts the target adjustment parameters.

[0034] The user can send a startup instruction for the air conditioner through a remote control or a terminal device. After the air conditioner receives the startup instruction, it starts up. After a period of time, when the indoor environmental temperature reaches the temperature required by the user, the air conditioner enters a stable operating state. At this time, the actual air outlet speed V1 of the air conditioner is obtained. From the formula M = V1 * R (where M is the air volume and R is the outlet area), it can be seen that after the air conditioner operates stably, the air outlet speed determines the air volume. Therefore, the air volume can be characterized by the air outlet speed to determine whether the air volume of the air conditioner has decreased. A wind speed sensor is provided at the air outlet of the indoor unit of the air conditioner. The processor of the air conditioner is communicatively connected to the wind speed sensor to obtain the actual air outlet speed V1 of the air conditioner. The relationship between the wind gear and the theoretical air outlet speed VL is also pre-stored in the processor, and each wind gear corresponds to a theoretical wind speed. Therefore, the theoretical air outlet speed VL corresponding to the current wind gear can be determined according to the relationship. Compare V1 and VL. If V1 < VL, it means that the air volume of the air conditioner has decreased due to some reasons. Therefore, the motor speed S of the fan is obtained at this time. Determine whether the motor speed S matches the current wind gear. According to the matching situation between the two, the target adjustment parameter to be adjusted is determined. Then the target adjustment parameter is adjusted. Among them, the target adjustment parameter is the motor speed or the operating mode of the air conditioner. The motor speed or the operating mode can be selected for adjustment according to the specific matching situation.

[0035] When using the method for controlling the air volume of an air conditioner provided by the embodiment of the present disclosure, if the actual air outlet speed of the air conditioner is less than the theoretical air outlet speed, the motor speed is obtained. The target adjustment parameter is determined based on whether the motor speed matches the current wind gear. In this way, based on the matching situation between the motor speed and the current wind gear, the appropriate target adjustment parameter is adjusted to more accurately adjust the air volume of the air conditioner, thereby ensuring the working efficiency of the air conditioner.

[0036] Combined Figure 2 As shown, the embodiment of the present disclosure provides another method for controlling the air volume of an air conditioner, including:

[0037] S101, the air conditioner obtains its actual air outlet speed.

[0038] S102, when the actual air outlet speed of the air conditioner is less than the theoretical air outlet speed, the motor speed of the fan is obtained.

[0039] S113, when the motor speed matches the current wind gear, the air conditioner determines that the target adjustment parameter is the operating mode of the air conditioner.

[0040] S123, when the motor speed does not match the current wind gear, the air conditioner determines that the target adjustment parameter is the motor speed.

[0041] S114, after the air conditioner executes S113, it adjusts the operating mode of the air conditioner according to the current operating mode of the air conditioner.

[0042] S124, after executing S123, the air conditioner adjusts the motor speed to match the current wind speed.

[0043] The fan speed range includes: silent, air supply, low, medium, high, and powerful. Different fan speeds correspond to different motor speeds and air output speeds. The higher the fan speed, the faster the motor speed, the greater the air output speed, and the greater the air volume.

[0044] If the motor speed matches the current wind speed, the fan motor is not stalled. The target adjustment parameter is then determined to be the air conditioner's operating mode. The air conditioner's operating mode is adjusted based on the air conditioner's current operating mode. Specifically, if the air conditioner is currently operating in cooling mode, the temperature of the inner coil is controlled to reach the temperature required for self-cleaning mode. The air conditioner is then controlled to operate in self-cleaning mode to self-clean the indoor heat exchanger. If the air conditioner is not currently operating in cooling mode, the air conditioner is first controlled to operate in cooling mode. After a period of time, when the temperature of the inner coil reaches the temperature required for self-cleaning mode, the air conditioner is again controlled to operate in self-cleaning mode.

[0045] If the motor speed does not match the current wind speed, it means that one of the reasons for the reduced air volume is that the motor loses rotation. Therefore, the target adjustment parameter is determined to be the motor speed. The motor speed is controlled to increase so that the motor speed matches the current wind speed. The air conditioner's processor pre-stores the correlation between the wind speed and the motor speed. Based on this correlation, the target speed corresponding to the current wind speed is determined. The motor speed is then controlled to increase to the target speed. Afterwards, the actual air outlet speed is compared with the theoretical air outlet speed again. If the actual air outlet speed is still lower than the theoretical air outlet speed, it means that the improvement in the air volume caused by the correction of the motor speed is not obvious. Therefore, the target adjustment parameter is determined to be the operating mode of the air conditioner at this time. The operating mode of the air conditioner is adjusted according to the current operating mode of the air conditioner. For details, please refer to the aforementioned control logic, which will not be repeated here.

[0046] This determines whether the motor speed matches the current airflow level. If so, the reduced airflow is ruled out as a result of motor loss. Based on the air conditioner's current operating mode, the system then determines whether to directly enter self-cleaning mode. After self-cleaning the indoor heat exchanger, the heat exchanger is no longer clogged and the airflow can be increased. If not, motor loss is a contributing factor to the reduced airflow. The motor speed is then adjusted to increase the airflow.

[0047] Combine Figure 3 As shown, the embodiment of the present disclosure provides another method for controlling the air volume of an air conditioner, including:

[0048] S101: The air conditioner obtains its actual air outlet speed.

[0049] S102: When the actual air outlet speed of the air conditioner is lower than the theoretical air outlet speed, the motor speed of the fan is obtained.

[0050] S113. When the motor speed of the air conditioner matches the current wind speed setting, determine the target adjustment parameter as the operating mode of the air conditioner.

[0051] S123. When the motor speed of the air conditioner does not match the current wind speed setting, determine the target adjustment parameter as the motor speed.

[0052] S114. After the air conditioner executes S113, adjust the operating mode of the air conditioner according to its current operating mode.

[0053] S124. After the air conditioner executes S123, adjust the motor speed to match the current wind speed setting.

[0054] S105. After the air conditioner executes S114 and the self-cleaning mode ends, obtain the actual air outlet speed after self-cleaning.

[0055] S106. When the actual air outlet speed after self-cleaning is less than the theoretical air outlet speed, calculate n = (Vy - Vx) / Vx. Here, n is the air speed difference ratio, Vx is the actual air outlet speed before self-cleaning, and Vy is the actual air outlet speed after self-cleaning.

[0056] S107. The air conditioner controls its operation according to the air speed difference ratio.

[0057] Before the self-cleaning mode runs, obtain the actual air outlet speed Vx, and at this time, Vx is also the actual air outlet speed before self-cleaning. After the self-cleaning mode ends, the air conditioner continues to run with the previous operating parameters. At the same time, obtain the current actual air outlet speed Vy, and at this time, Vy is also the actual air outlet speed after self-cleaning. Compare the current actual air outlet speed with the theoretical air outlet speed. If the current actual air outlet speed is still less than the theoretical air outlet speed, it means that the air volume has not been effectively increased after cleaning the indoor heat exchanger. Therefore, at this time, calculate the air speed difference ratio according to the following formula:

[0058] n = (Vy - Vx) / Vx

[0059] In the above formula, n is the air speed difference ratio. The air speed difference ratio can characterize the difference in the air outlet speed of the indoor unit before and after the self-cleaning mode, and then judge whether the self-cleaning is obvious for improving the air volume. Control the operation of the air conditioner according to the air speed difference ratio to further increase the air volume.

[0060] Optionally, in step S107, the air conditioner controls its operation according to the air speed difference ratio, including:

[0061] When n1 < n ≤ n2, the air conditioner corrects the motor speed of the air conditioner fan.

[0062] When n > n2, the air conditioner controls it to run the self-cleaning mode again.

[0063] Among them, n1 is the first difference ratio threshold, and n2 is the second difference ratio threshold.

[0064] The first difference ratio threshold n1 and the second difference ratio threshold n2 are pre-stored in the processor of the air conditioner. If n1 < n ≤ n2, it indicates that the actual air outlet speed Vy after self-cleaning is small, which further indicates that the self-cleaning effect is not obvious, that is, the indoor heat exchanger is already in a relatively clean state at this time. There is no need to clean the indoor heat exchanger again at this time. Therefore, the motor speed is corrected at this time to increase the air outlet speed again by correcting the motor speed. If n > n2, it indicates that the actual air outlet speed Vy after self-cleaning is large, which further indicates that the self-cleaning effect is relatively obvious. Therefore, at this time, the air conditioner is controlled to run the self-cleaning mode again to deeply clean the indoor heat exchanger and further increase the air outlet speed. In this way, after the air conditioner finishes one self-cleaning, the wind speed difference ratio is calculated, and based on the wind speed difference ratio, the motor speed is corrected or the secondary self-cleaning is run to select a suitable means to increase the air outlet speed.

[0065] Optionally, the air conditioner corrects the motor speed of the air conditioner fan, including:

[0066] The air conditioner determines the target correction strategy for the motor speed according to the range where the wind speed difference ratio is located.

[0067] The air conditioner controls the motor to operate according to the target correction strategy.

[0068] A more detailed wind speed difference ratio range is pre-divided between n1 and n2 and stored in the processor of the air conditioner. If n1 < n ≤ n2, the range where the wind speed difference ratio is located is determined. The target correction strategy for the motor speed is determined according to the range where the wind speed difference ratio is located, and then the motor is controlled to operate according to the target correction strategy. Optionally, n1 is 0.2% and n2 is 0.8%. In this way, according to the range where the wind speed difference ratio is located, a suitable correction strategy is matched for the motor speed to appropriately increase the air volume, avoiding excessive increase in the air volume beyond the user's demand or insufficient increase in the air volume not meeting the user's demand.

[0069] Optionally, the air conditioner determines the target correction strategy for the motor speed according to the range where the wind speed difference ratio is located. It includes:

[0070] When n1 < n ≤ n3, the air conditioner determines to correct the motor speed of the air conditioner fan according to its operating mode.

[0071] When n3 < n ≤ n2, the air conditioner determines to first increase the motor speed according to a preset ratio.

[0072] When the air outlet speed after increasing the motor speed is less than the theoretical air outlet speed, the air conditioner determines to further correct the motor speed of the air conditioner fan according to its operating mode.

[0073] Among them, n3 is the third difference ratio threshold value.

[0074] The third difference ratio threshold value n3 is pre-stored in the processor of the air conditioner, and n1 < n3 < n2. n3 divides n1 to n2 into a first range (n1, n3] and a second range (n3, n2]. Optionally, n3 is 0.5%. If the wind speed difference ratio n is within the first range, it indicates that the change in the air outlet speed before and after self-cleaning is relatively small. Therefore, at this time, the motor speed is corrected according to the operating mode of the air conditioner to more finely increase the air outlet speed. If the wind speed difference ratio n is within the second range, it indicates that the change in the air outlet speed before and after self-cleaning is relatively large. Therefore, at this time, the motor speed is roughly increased according to a preset ratio, and then the actual air outlet speed is compared with the theoretical air outlet speed again. If the actual air outlet speed is greater than or equal to the theoretical air outlet speed, the motor is controlled to maintain the current speed, and the speed compensation process ends. If the actual air outlet speed is still less than the theoretical air outlet speed, the motor speed is further finely corrected according to the operating mode of the air conditioner. Optionally, the preset ratio is S1 * n, where S1 is the current motor speed, that is, the motor speed is increased to S1 * (1 + n). In this way, based on the difference in the air outlet speed before and after self-cleaning, the motor speed is finely or roughly corrected to simplify the process of motor speed correction and make the logic simpler.

[0075] Optionally, the air conditioner corrects the motor speed of the air conditioner fan according to its operating mode, including:

[0076] The air conditioner obtains a new actual air outlet speed.

[0077] The air conditioner calculates the wind speed ratio of the new actual air outlet speed to the theoretical air outlet speed.

[0078] When the air conditioner is operating in the cooling mode / dehumidifying mode, if the wind speed ratio is within the first interval, the motor speed is corrected to the first target speed; if the wind speed ratio is within the second interval, the motor speed is corrected to the second target speed; if the wind speed ratio is within the third interval, the motor speed is corrected to the third target speed.

[0079] When the air conditioner is operating in the heating mode, if the wind speed ratio is in the first interval or the second interval, the motor speed is corrected to the second target speed; if the wind speed ratio is in the third interval, the motor speed is corrected to the third target speed.

[0080] Among them, the lower limit value of the first interval is greater than the upper limit value of the second interval, and the lower limit value of the second interval is greater than the upper limit value of the third interval. The first target speed is less than the second target speed, and the second target speed is less than the third target speed.

[0081] The wind speed sensor is used to obtain the new actual air outlet speed, that is, the current actual air outlet speed. The ratio of the new actual air outlet speed to the theoretical air outlet speed is calculated and defined as the wind speed ratio m. The air conditioner processor pre-stores wind speed ratio intervals, specifically a first interval [m2, m1), a second interval [m3, m2), and a third interval (-∞, m3). m1>m2>m3. Optionally, m1 is 0.98, m2 is 0.95, and m3 is 0.93.

[0082] Further determine the current operating mode of the air conditioner. If the cooling mode / dehumidification mode is currently running, the target speed of the motor is further determined based on the interval in which the wind speed ratio is located. Specifically, if m∈[m2,m1), the motor speed is corrected to the first target speed S'. If m∈[m3,m2), the motor speed is corrected to the second target speed S". If m∈(-∞,m3), the motor speed is corrected to the third target speed S"'. Among them, S'>S">S"'. In this way, the smaller the interval in which m is located, the smaller the new actual air outlet speed is than the theoretical air outlet speed, and the more the motor speed needs to be increased. Optionally, S'=S1+S1*(1-n), S"=S1 / n, S"' is the motor speed corresponding to a wind speed one wind speed higher than the current wind speed. Among them, S1 is the current motor speed.

[0083] If the heating mode is currently running, the target speed of the motor is further determined based on the interval in which the wind speed ratio is located. Specifically, if m∈[m2,m1) or m∈[m3,m2), the motor speed is corrected to the second target speed S". This is because the physical sensation in the heating mode is weaker than that in the cooling mode, so the first interval and the second interval can correspond to the same target speed. If m∈(-∞,m3), the motor speed is corrected to the third target speed S'".

[0084] In this way, the motor speed is corrected to different target speeds according to the current operating mode of the air conditioner and the current wind speed ratio range, thereby making the control of the motor speed more refined and improving the accuracy of adjusting the air volume.

[0085] Optionally, when the air conditioner is controlled to operate in self-cleaning mode again, if the self-cleaning mode ends, a new actual air outlet speed is obtained, i.e., the current actual air outlet speed. If the new actual air outlet speed is still less than the theoretical air outlet speed, the fan motor speed is corrected according to the air conditioner's operating mode according to the logic described above, which will not be repeated here. In this way, after the indoor heat exchanger has been self-cleaned a second time, if the new actual air outlet speed is still less than the theoretical air outlet speed, the motor speed is fine-tuned according to the air conditioner's operating mode to improve the accuracy of the air volume adjustment.

[0086] Combine Figure 4As shown, an embodiment of the present disclosure provides a device 40 for controlling the air volume of an air conditioner, including: a first acquisition module 41 , a second acquisition module 42 , a determination module 43 and an adjustment module 44 .

[0090] The adjustment module 44 is configured to adjust the target adjustment parameter.

[0091] Using the apparatus for controlling the airflow rate of an air conditioner provided by an embodiment of the present disclosure, if the actual airflow rate of the air conditioner is less than the theoretical airflow rate, the motor speed is obtained. A target adjustment parameter is determined based on whether the motor speed matches the current wind speed setting. Thus, based on the matching of the motor speed and the current wind speed setting, the appropriate target adjustment parameter is adjusted to more accurately adjust the airflow rate of the air conditioner, thereby ensuring the operating efficiency of the air conditioner.
