Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of air conditioners, in particular to an air conditioner and a control method and device thereof. BACKGROUND

[0002] In the operation process of the air conditioner, when the user adjusts the position of the air deflector, the air outlet of the air conditioner may blow towards the panel, resulting in excessively low panel temperature or cold air continuing to flow upwards along the panel and mixing with the return air to enter the air conditioner, which may cause condensation problems. SUMMARY

[0003] Therefore, the present application provides an air conditioner and a control method and device thereof to prevent air conditioner cold air backflow and properly solve the condensation problem, thereby improving user experience.

[0004] To solve the above problems, the present application provides an air conditioner and a control method and device thereof. The control method comprises: determining whether the air conditioner has a condensation risk; recording the current air deflector angle (A1, A2) of the air conditioner in the case where the air conditioner has a condensation risk; and in response to an adjustment instruction for the air deflector angle, determining a target air deflector angle of the air conditioner according to the adjustment instruction and the current air deflector angle (A1, A2), and controlling the air conditioner to maintain the target air deflector angle.

[0005] Compared with the prior art, the technical effects achieved by adopting the technical solution are as follows: in the case where the air conditioner has a condensation risk, the current air deflector angle (A1, A2) is recorded, when the air deflector angle of the air conditioner falls within the range of the current air deflector angle (A1, A2), the air conditioner has a condensation risk, the adjustment instruction for the air deflector angle is issued, the air conditioner adjusts the air deflector angle according to the adjustment instruction and the current air deflector angle (A1, A2), prevents the cold air discharged by the air conditioner from directly blowing against the panel of the air conditioner, and prevents the cold air from returning to the air inlet to cause condensation, so that the target air deflector angle of the air conditioner does not fall within the range of the current air deflector angle (A1, A2), and the air conditioner is controlled to continue running.

[0006] Further, the panel of the air conditioner is provided with an air pressure sensor; determining whether the air conditioner has a condensation risk specifically comprises: determining whether the air conditioner has a condensation risk according to the air pressure P obtained by the air pressure sensor, and the inner ring temperature and the return air temperature of the air conditioner.

[0007] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: the wind pressure sensor is arranged on the panel of the air conditioner, the obtained wind pressure data is more accurate, the wind pressure on the panel is detected to determine whether the cold wind led out by the air conditioner directly blows on the panel of the air conditioner to cause condensation; the return air temperature of the air conditioner and the inner ring temperature are obtained, and the difference between the inner ring temperature and the return air temperature is analyzed, the greater the difference is, the lower the return air temperature is, which indicates that the cold wind led out by the air conditioner returns to the inside of the air conditioner through the air inlet, wherein the return air temperature is the temperature at the air inlet of the air conditioner, and the inner ring temperature is the temperature of the indoor space; thus, it can be determined whether the air conditioner has a condensation risk, and the determination of the condensation risk is more reliable by combining the wind pressure and the temperature difference.

[0008] Further, according to the wind pressure P collected by the wind pressure sensor and the inner ring temperature T 内环 and the return air temperature T 回风 of the air conditioner, it is determined whether the air conditioner has a condensation risk, specifically including: in the case that the wind pressure P is greater than the wind pressure threshold P 阈 , and the difference ΔT 内环 between the inner ring temperature T 回风 and the return air temperature T 内环-回风 is greater than the first temperature difference threshold Δ T阈1 , it is determined that the air conditioner has a condensation risk; and / or in the case that the wind pressure P is less than the wind pressure threshold P 阈 , it is determined that the air conditioner does not have a condensation risk; and / or in the case that the difference ΔT 内环 between the inner ring temperature T 回风 and the return air temperature T 内环-回风 is less than the first temperature difference threshold Δ T阈1 , it is determined that the air conditioner does not have a condensation risk.

[0009] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: the wind pressure P is compared with the wind pressure threshold P 阈 , and the difference ΔT 内环 between the inner ring temperature T 回风 and the return air temperature T 内环-回风 is compared with the first temperature difference threshold Δ T阈1 , when the wind pressure P is greater than the wind pressure threshold P 阈 , the air led out by the air conditioner blows towards the panel of the air conditioner, the indoor air condenses when meeting the low-temperature panel of the air conditioner to form condensation, and when the difference ΔT 内环-回风 is greater than the first temperature difference threshold Δ T阈1 , the cold wind led out by the air conditioner returns to the air conditioner again through the air inlet without acting on the indoor air, therefore, by combining the wind pressure and the temperature difference, it is determined whether the air conditioner has a condensation risk, and the determination result is more accurate.

[0010] Further, the current deflection angle (A1, A2) of the air conditioner is recorded, specifically including: driving the deflector to rotate one circle in the current operation mode of the air conditioner, and recording the current deflection angle (A1, A2) of the air conditioner.

[0011] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: the air conditioner drives the deflector to rotate one circle in the current operation mode, records the current deflection angle (A1, A2) of the deflector, and (A1, A2) is the angle range in which the air conditioner has a risk of condensation. When the deflection angle of the air conditioner falls within the range of the current deflection angle (A1, A2), it is determined that the air conditioner has a risk of condensation.

[0012] Further, according to the adjustment instruction and the current deflection angle (A1, A2), the target deflection angle of the air conditioner is determined, including: in the case where the set deflection angle does not fall within the range of the current deflection angle (A1, A2), determining the target deflection angle of the air conditioner as the set deflection angle; in the case where the set deflection angle falls within the range of the current deflection angle (A1, A2), determining the target deflection angle of the air conditioner as the end point value closest to the set deflection angle in the current deflection angle (A1, A2); wherein the set deflection angle is the deflection angle indicated by the adjustment instruction.

[0013] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: in the case where the set deflection angle falls within the range of the current deflection angle (A1, A2), the air conditioner has a risk of condensation, so the set deflection angle of the air conditioner is adjusted to the end point value closest to the current deflection angle, thereby avoiding the risk of condensation. When the set deflection angle does not fall within the range of the current deflection angle (A1, A2), the air conditioner does not have a risk of condensation, and the air conditioner operates at the set deflection angle.

[0014] Further, in the case where the target deflection angle is inconsistent with the set angle, after controlling the air conditioner to maintain the target deflection angle, the control method further includes: in response to the adjustment instruction for the comfort level, controlling the air conditioner to operate at the set deflection angle, and controlling the air conditioner to execute the anti-condensation mode; wherein the set deflection angle is the deflection angle indicated by the adjustment instruction.

[0015] Compared with the prior art, the technical effects achieved by adopting the technical scheme are: in response to the adjustment instruction for the comfort level, the air conditioner operates at the set deflection angle and executes the anti-condensation mode, which not only meets the actual needs of the user, but also prevents the air conditioner from producing condensation, thereby improving the user experience.

[0016] Further, the anti-condensation mode specifically includes: controlling the air conditioner to reduce the gear of the indoor fan, and judging again whether the air conditioner has a risk of condensation; in the case where the air conditioner still has a risk of condensation, controlling the air conditioner to continue to reduce the gear of the indoor fan again.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: when there is a risk of condensation in the air conditioner, an anti-condensation mode is implemented. This is achieved by adjusting the indoor fan speed and regulating the air volume, and by determining whether cold air is recirculated, thereby reducing the difference between the inner ring temperature and the return air temperature and solving the condensation problem.

[0018] Furthermore, the anti-condensation mode specifically includes: when the air conditioner has already reduced the indoor fan speed to the lower limit, controlling the air conditioner to restore the indoor fan speed to the original speed and controlling the air conditioner to reduce the compressor frequency. The original speed is the speed at which the air conditioner starts to execute the anti-condensation mode.

[0019] Compared with existing technologies, the technical effects achieved by this solution are as follows: Even when the indoor fan of an air conditioner is reduced to its lowest setting, there is still a risk of condensation. By restoring the indoor fan to its original setting and reducing the compressor frequency, the compressor compresses the gaseous refrigerant into a high-temperature, high-pressure liquid refrigerant, driving the refrigerant flow and thus removing heat from the room and lowering the indoor temperature. Reducing the compressor frequency slows down the refrigerant flow, decreasing the rate at which the air conditioner delivers low-temperature air, reducing the temperature difference between the inner ring and return air, and simultaneously reducing the amount of low-temperature air blown onto the panel, thus preventing condensation from forming on the panel. This solves the condensation problem, meets user needs, and improves the user experience.

[0020] Furthermore, after controlling the air conditioner to reduce the compressor frequency, the control method also includes: maintaining the inner ring temperature T 内环 With return air temperature T 回风 The difference ΔT between 内环-回风 Less than the second temperature difference threshold ΔT 阈2 In this case, the air conditioner will stop reducing the compressor frequency and continue operating at the current frequency.

[0021] Compared with existing technologies, the technical effects achieved by this solution are as follows: After the air conditioner reduces the compressor frequency, the difference between the inner ring temperature and the return air temperature is compared with a second temperature difference threshold. When the difference between the inner ring temperature and the return air temperature is less than the second temperature difference threshold, there is no risk of condensation in the air conditioner. Specifically, when the difference between the inner ring temperature and the return air temperature is small, the temperature inside the air conditioner drops slowly, and the temperature difference with the room gradually decreases, thereby reducing the formation of condensation.

[0022] Furthermore, the present invention also provides a control device that executes a control method, specifically including: a recording module that receives various types of data, and a judgment module that outputs control commands based on the various types of data from the recording module.

[0023] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: The control device of the present invention implements the control method of the air conditioner of any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner of any technical solution of the present invention, which will not be elaborated here.

[0024] Furthermore, the present invention also provides an air conditioner, which includes: an air conditioner body, a fan, a compressor, and a control device, wherein the control device is disposed in the air conditioner body and controls the operation of the air conditioner; wherein the control device is capable of executing the control method of the air conditioner.

[0025] Compared with the prior art, the technical effects achieved by adopting this technical solution are as follows: the air conditioner of the present invention implements the control method of the air conditioner of any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner of any technical solution of the present invention, which will not be repeated here.

[0026] By adopting the technical solution of the present invention, the following technical effects can be achieved:

[0027] (1) Install a wind pressure sensor on the air conditioner panel. Based on the wind pressure P, inner ring temperature and return air temperature, data support is provided for judging the risk of condensation, making the judgment of the risk of condensation more reliable.

[0028] (2) Wind pressure P and wind pressure threshold P 阈 Inner ring temperature T 内环 With return air temperature T 回风 The difference ΔT between 内环-回风 With the first temperature difference threshold Δ T阈1 By comparing the data, we can accurately determine whether there is a risk of condensation in the air conditioner;

[0029] (3) Even when the air conditioner is reduced to the lower limit, there is still a risk of condensation. The indoor fan is restored to its original setting and the compressor frequency is reduced to solve the condensation problem, meet the user's needs, and improve the user's experience.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Specifically, embodiments of the present invention provide a control method for an air conditioner, including:

[0039] S100. Determine if there is a risk of condensation in the air conditioner;

[0040] S200, Record the current airflow angle of the air conditioner (A1, A2);

[0041] In cases where there is a risk of condensation on the air conditioner, S200 shall be implemented.

[0042] S300, Determine the target air guide angle for the air conditioner;

[0043] In response to the adjustment command for the air guide angle, the target air guide angle of the air conditioner is determined according to the adjustment command and the current air guide angle (A1, A2).

[0044] S400, control the air conditioner to maintain the target airflow angle.

[0045] For example, see attached Figure 1 As shown, when there is a risk of condensation in the air conditioner, the current air guide angle of the air conditioner is recorded and a data range (A1, A2) is formed. When the air guide angle of the air conditioner falls within (A1, A2), there is a risk of condensation in the air conditioner. The air conditioner issues an adjustment command to select an air guide angle outside the range of (A1, A2) to prevent the cold air vented by the air conditioner from blowing directly onto the air conditioner panel. The target air guide angle of the air conditioner is determined and the air conditioner is controlled to maintain the target air guide angle to prevent the cold air vented by the air conditioner from blowing onto the air conditioner panel or returning to the air conditioner through the air inlet, thereby solving the condensation problem and improving the user experience.

[0046] Specifically, the air conditioner panel is equipped with a wind pressure sensor; to determine whether there is a risk of condensation in the air conditioner, the following methods are used: based on the wind pressure P collected by the wind pressure sensor, as well as the inner ring temperature and return air temperature of the air conditioner, to determine whether there is a risk of condensation in the air conditioner.

[0047] Preferably, a wind pressure sensor is installed on the air conditioner panel to collect more accurate wind pressure values. On the one hand, by detecting the wind pressure on the air conditioner panel, it can be determined whether the cold air discharged from the air conditioner is blowing towards the air conditioner panel, thus causing condensation. On the other hand, a temperature sensor is installed at the air inlet of the air conditioner to obtain the return air temperature value. At the same time, the indoor temperature is detected to obtain the temperature difference between the inner ring temperature and the return air temperature. This allows it to be determined whether the cold air discharged from the air conditioner is acting on the indoor environment. When the temperature difference is too large, it can be concluded that the cold air discharged from the air conditioner returns to the air conditioner through the air inlet and does not act on the indoor environment, thus causing condensation. By jointly analyzing the differences between wind pressure, inner ring temperature, and return air temperature, a judgment on the risk of condensation can be made, making the results more accurate.

[0048] Specifically, based on the wind pressure P collected by the wind pressure sensor and the inner ring temperature T of the air conditioner... 内环 and return air temperature T 回风 To determine if an air conditioner has a risk of condensation, the following measures are taken: when the air pressure P is greater than the air pressure threshold P... 阈 And the inner ring temperature T 内环 With return air temperature T 回风 The difference ΔT between 内环-回风 Greater than the first temperature difference threshold Δ T阈1 In cases where the air conditioner is deemed to have a risk of condensation, and / or when the wind pressure P is less than the wind pressure threshold P 阈 In the case of an air conditioner that is deemed to have no risk of condensation, and / or in an environment where the inner ambient temperature T 内环 With return air temperature T 回风 The difference ΔT between 内环-回风 Less than the first temperature difference threshold Δ T阈1 In this case, it can be determined that there is no risk of condensation on the air conditioner.

[0049] For details, please see the attached document. Figure 2 As shown, wind pressure P is compared with wind pressure threshold P. 阈 For comparison, the wind pressure P is greater than the wind pressure threshold P. 阈 In this situation, the air blown by the air conditioner is directed towards the control panel, causing the panel temperature to drop. This results in a significant temperature difference between the panel and the room, causing the indoor air to condense and form condensation. The inner ring temperature T is then measured. 内环 With return air temperature T 回风 The difference ΔT 内环-回风 The difference ΔT 内环-回风 First temperature difference threshold Δ T阈1In comparison, the inner air temperature is higher than the return air temperature. The indoor air condenses at the air inlet, forming condensation. This occurs when the air pressure P is lower than the air pressure threshold P. 阈 and / or difference ΔT 内环-回风 Less than Δ T阈 In such cases, it is not possible to determine whether an air conditioner is at risk of condensation based on a single set of data; therefore, it is necessary to combine two sets of data for a joint assessment.

[0050] For example, recording the current air guide angle (A1, A2) of the air conditioner specifically includes: controlling the air conditioner to drive the air guide plate to rotate one revolution in the current operating mode and recording the current air guide angle (A1, A2) of the air conditioner.

[0051] Specifically, the air conditioner's air guide vane rotates one full turn and returns to the air guide angle before the air conditioner rotates, generating the current air guide angle range (A1, A2). When the air guide angle of the air conditioner falls within the range of (A1, A2), the air conditioner is at risk of condensation. Therefore, using the current air guide angle (A1, A2) to determine whether there is a risk of condensation at the target air guide angle of the air conditioner is more intuitive.

[0052] Specifically, based on the adjustment command and the current air guide angle (A1, A2), determining the target air guide angle of the air conditioner includes: if the set air guide angle does not fall within the range of the current air guide angle (A1, A2), the target air guide angle of the air conditioner is determined to be the set air guide angle; if the set air guide angle falls within the range of the current air guide angle (A1, A2), the target air guide angle of the air conditioner is determined to be the endpoint value of the current air guide angle (A1, A2) that is closest to the set air guide angle; wherein, the set air guide angle is the air guide angle indicated by the adjustment command, and the range of the current air guide angle (A1, A2) does not include the two endpoints A1 and A2.

[0053] Specifically, in the current operating mode, the air conditioner controls the air guide vane to rotate one revolution and records the current air guide angle (A1, A2). (A1, A2) is the angle range where the air conditioner has a risk of condensation. When the air guide angle of the air conditioner falls within the range of the current air guide angle (A1, A2), it can be determined that the air conditioner has a risk of condensation.

[0054] For details, please see the attached document. Figure 2 As shown, the air conditioner assesses the risk of condensation.

[0055] S100, obtain the difference T between wind pressure P, inner ring temperature and return air temperature;

[0056] S200, P and P 阈 Compare T with the first temperature difference threshold T1;

[0057] S300, the air conditioner has a risk of condensation;

[0058] S310, the air conditioner has no risk of condensation;

[0059] Where P > P 阈 If T > T1, execute S300; if P < P 阈 If T < T1, then execute S310.

[0060] S400, Record the current airflow angle of the air conditioner (A1, A2);

[0061] S500: Determine whether the set air guide angle falls within the current air guide angle (A1, A2);

[0062] S510. Determine the target air guide angle as the set air guide angle;

[0063] S520. Determine the target wind guide angle as the endpoint value among the current wind guide angles (A1, A2) that is closest to the set wind guide angle.

[0064] Specifically, if the set air guide angle does not fall within the current air guide angle (A1, A2), S510 is executed; if the set air guide angle falls within the current air guide angle (A1, A2), S520 is executed.

[0065] For example, when the target air guide angle is inconsistent with the set angle, after controlling the air conditioner to maintain the target air guide angle, the control method further includes: in response to the adjustment command for the comfort level, controlling the air conditioner to operate at the set air guide angle, and controlling the air conditioner to execute the anti-condensation mode; wherein, the set air guide angle is the air guide angle indicated by the adjustment command.

[0066] When the target airflow angle is inconsistent with the set airflow angle, and the user reports discomfort through the remote control or mobile phone, the air conditioner outputs an adjustment command based on the comfort level and operates at the set airflow angle to meet the user's needs to a limited extent. It also executes the anti-condensation mode to solve the condensation problem and improve the user experience.

[0067] Specifically, the anti-condensation mode includes: controlling the air conditioner to reduce the speed of the indoor fan and reassessing whether there is a risk of condensation in the air conditioner; if there is still a risk of condensation in the air conditioner, controlling the air conditioner to further reduce the speed of the indoor fan.

[0068] Specifically, the anti-condensation mode works by reducing the indoor fan speed and airflow to raise the temperature of the air discharged from the air conditioner, thus reducing the temperature difference between the indoor temperature and the air conditioner's intake temperature. After reducing the indoor fan speed, the system reassesses whether there is a risk of condensation, ensuring the effectiveness of the anti-condensation mode and improving the user experience.

[0069] As attached Figure 3 As shown, the air conditioner is in anti-condensation mode;

[0070] S100, the air conditioner is in anti-condensation mode;

[0071] S200, reduce the speed of the indoor fan;

[0072] S300, Determine if there is a risk of condensation in the air conditioner;

[0073] If there is a risk of condensation on the air conditioner, continue to execute S200 until there is no risk of condensation on the air conditioner, then maintain the current indoor fan speed and the air conditioner continues to run.

[0074] Specifically, the anti-condensation mode includes: when the air conditioner has already reduced the indoor fan speed to the lower limit, controlling the air conditioner to restore the indoor fan speed to the original speed and controlling the air conditioner to reduce the compressor frequency. The original speed is the speed at which the air conditioner starts to implement the anti-condensation mode.

[0075] Specifically, even when the indoor fan is reduced to its lowest setting, the air conditioner still faces the risk of condensation. The indoor fan is then restored to the setting it was at when the anti-condensation mode was first activated, and the compressor frequency is reduced. The compressor compresses the gaseous refrigerant into a high-temperature, high-pressure liquid refrigerant, driving the refrigerant flow and thus removing heat from the room, lowering the indoor temperature. Reducing the compressor frequency slows the refrigerant flow, increasing the temperature of the air exiting the air conditioner and decreasing the temperature difference between the inner and return air. Simultaneously, the airflow angle is adjusted to reduce the amount of low-temperature air blown onto the panel, preventing condensation from forming on the panel. This solves the condensation problem, meets user needs, and improves the user experience.

[0076] In an air conditioner, the compressor compresses and drives the refrigerant, drawing it from the low-pressure zone, compressing it, and delivering it to the high-pressure zone. Heat is dissipated into the air through the heat sink, and the refrigerant changes from a gaseous state to a liquid state. Reducing the compressor frequency slows down the refrigerant flow, raising the temperature of the gas discharged from the air conditioner, and alleviating the liquefaction of cold air upon heating, thus solving the condensation problem.

[0077] After controlling the air conditioner to reduce the compressor frequency, the control method also includes: setting the inner ring temperature T... 内环 With return air temperature T 回风 The difference ΔT between 内环-回风 Less than the second temperature difference threshold ΔT 阈2 In this case, the air conditioner will stop reducing the compressor frequency and continue operating at the current frequency.

[0078] Among them, as attached Figure 4 As shown, the air conditioner is in anti-condensation mode;

[0079] S100, Air conditioners pose a risk of condensation;

[0080] S200, indoor fan reduced to the lowest setting;

[0081] S300, indoor fan restored to original setting;

[0082] S400, reduce compressor frequency;

[0083] S500, compare T with the second temperature difference threshold T2;

[0084] S600, the compressor is operating at the current frequency;

[0085] Specifically, if T > T2, continue executing S400; if T < T2, execute S600.

[0086] When the compressor frequency decreases, the temperature of the cold air discharged from the air conditioner increases. At this point, when the cold air returns to the air conditioner, the intake air temperature also increases. Therefore, the inner ambient temperature T... 内环 With return air temperature T 回风 The difference ΔT between 内环-回风 Less than the second temperature difference threshold ΔT 阈2 The temperature difference between the inner ring temperature and the return air temperature is reduced, thus solving the condensation problem.

[0087] This invention also provides a control device that executes a control method, specifically including: a recording module 210 that receives various types of data, and a judgment module 220 that outputs control commands based on the various types of data from the recording module 210.

[0088] As attached Figure 5 As shown, the control device includes a recording module 210 and a judgment module 220. The recording module 210 records the current air guide angle (A1, A2), the value of the air pressure P, and the inner ring temperature T. 内环 and return air temperature T 回风 The data is collected and fed back to the judgment module 220. Based on the data from the recording module 210, the judgment module 220 controls the air conditioner to adjust the air guide angle, reduce the indoor fan speed, and reduce the compressor frequency to solve the condensation problem.

[0089] This invention also provides an air conditioner, which includes: an air conditioner body 100, a fan 110, a compressor 120, and a control device 200. The control device 200 is disposed in the air conditioner body 100 and controls the operation of the air conditioner; wherein, the control device 200 is capable of executing the control method of the air conditioner.

[0090] The air conditioner of the present invention implements the control method of the air conditioner of any technical solution of the present invention, and therefore has all the beneficial effects of the control method of the air conditioner of any technical solution of the present invention, which will not be repeated here.
