Description

Technical Field

[0001] This invention relates to the field of dehumidification, and more specifically, to a control method and control device for a dehumidifier and an air conditioner. Background Technology

[0002] With the development of technology, dehumidifiers have gradually entered thousands of households and become one of the common appliances in people's daily lives. A dehumidifier works by drawing humid air into the machine, causing water molecules in the air to condense into water droplets, and then expelling dry air outside, thus maintaining a suitable relative humidity indoors. Most existing dehumidifiers use humidity sensors to detect the humidity of the surrounding environment and control whether the dehumidifier turns off based on the sensor's detection results.

[0003] However, relying solely on humidity sensors to detect the overall humidity of a room is inaccurate. In complex environments or large spaces, errors in the humidity sensor's readings may cause the device to shut down prematurely, impacting the user experience. Therefore, it is essential to provide a more accurate control method for dehumidifiers that detects ambient humidity. Summary of the Invention

[0004] The present invention aims to solve at least one of the above-mentioned technical problems.

[0005] Therefore, the first objective of this invention is to provide a control method for a dehumidifier.

[0006] A second objective of this invention is to provide a control device for a dehumidifier.

[0007] A third objective of this invention is to provide an air conditioner.

[0008] To achieve the first objective of this invention, this invention provides a control method for a dehumidifier, the control method comprising: continuously detecting the real-time flow rate F of the dehumidifier at various time points within a target time period t. 实时 And detect the ambient temperature T of the environment where the dehumidifier is located. 环境 According to real-time traffic F 实时 Obtain the amount of water removed by the dehumidifier W within the target time period t; based on the amount of water removed W and the ambient temperature T... 环境 Determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 Based on the calculated humidity value H 计算 Control the operation of the dehumidifier.

[0009] Compared with existing technologies, the technical effects achieved by this technical solution are as follows: In the dehumidifier of the present invention, the real-time flow rate F of the dehumidifier at various time points within a time period t is detected. 实时 via F 实时The amount of water removed by the dehumidifier W within a period t can be calculated, thereby determining the calculated humidity value H of the environment in which the dehumidifier is located. 计算 Calculate the humidity value H 计算 It is a relatively accurate environmental humidity value with a small error compared to the actual environmental humidity. This is achieved by calculating the humidity value H. 计算 This control method can effectively prevent the humidity sensor from malfunctioning and affecting the dehumidifier's operation when the dehumidification environment is complex or the space is too large, thus providing users with a better user experience.

[0010] In addition, the technical solution provided by the present invention may also have the following technical features:

[0011] In the above technical solution, the water removal capacity W is calculated using equation (I):

[0012] W = π × r 2 ×g×t formula (I); where π is the ratio of π to 1. Where π is the mathematical constant pi, t0 is the start time of period t, t1 is the end time of period t, and f(t) is a function relating time and flow velocity.

[0013] Compared with existing technologies, the technical effect achieved by this technical solution is as follows: the amount of water removed is the amount of moisture removed from the air by the dehumidifier during continuous operation within a cycle t. The amount of water removed by the dehumidifier within a cycle t can be easily calculated using formula (I) in order to obtain the ambient humidity of the dehumidifier.

[0014] In any of the above technical solutions, based on the water removal capacity W and the ambient temperature T 环境 Determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 Specifically, this includes: obtaining the initial humidity value H of the environment where the dehumidifier is located at the start of the target time period t. 起始 Based on the water removal capacity W and the ambient temperature T 环境 Determine the humidity change ΔH of the environment in which the dehumidifier is located within the target time period t; based on the initial humidity value H... 起始 The difference between the humidity change value ΔH and the humidity change value ΔH is used to determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 Among them, the initial humidity value H 起始 The value is the relative humidity obtained using a humidity sensor.

[0015] Compared with existing technologies, the technical effects achieved by this technical solution are: initial humidity value H 起始 Using a humidity sensor for detection provides a relatively accurate and convenient way to obtain the initial humidity H. Since the dehumidifier removes a certain amount of moisture from the air after running for a period of time, causing changes in the ambient humidity, the initial humidity value H is used. 起始The calculated humidity value H of the environment in which the dehumidifier is located is determined by subtracting the humidity change value ΔH from the humidity change value. 计算 The results are relatively accurate.

[0016] In any of the above technical solutions, based on the water removal capacity W and the ambient temperature T 环境 Determine the humidity change ΔH of the environment in which the dehumidifier is located within the target time period t. Specifically, this includes: looking up the value of the humidity change ΔH in the absolute humidity and relative humidity correspondence table at ambient temperature T. 环境 Below, the absolute humidity value ρ is consistent with the value of the water removal capacity W. ω In the table of absolute humidity and relative humidity, find the value corresponding to the absolute humidity ρ. ω The corresponding relative humidity value RH is used, and the relative humidity value RH is used as the humidity change value ΔH.

[0017] Compared with existing technologies, the technical effects achieved by this solution are as follows: Since environmental humidity has certain standards, and the initial humidity value H measured by the humidity sensor... 起始 For relative humidity, therefore, it is the same as the initial humidity value H. 起始 Correspondingly, the humidity change value ΔH should also be the relative humidity, based on the water removal capacity W and the ambient temperature T. 环境 By referring to the absolute humidity and relative humidity correspondence table, the humidity change value ΔH can be obtained, thus yielding the calculated humidity value H of the environment where the dehumidifier is located. 计算 .

[0018] In any of the above technical solutions, based on the calculated humidity value H 计算 Controlling the operation of the dehumidifier specifically includes: determining the target humidity H of the environment in which the dehumidifier is located when it is turned on. 目标 ; In calculating the humidity value H 计算 Achieve target humidity H 目标 In such cases, control the dehumidifier to stop.

[0019] Compared with existing technologies, the technical effects achieved by this solution are: the target humidity H of the dehumidifier. 目标 Calculate the humidity value H to represent the desired humidity level of the environment after the dehumidifier is activated. 计算 The humidity of the environment is calculated by the dehumidifier based on the amount of water removed. When the calculated humidity value H... 计算 Achieve target humidity H 目标 At this point, the error between the ambient humidity and the target humidity is small, resulting in a good dehumidification effect.

[0020] In any of the above technical solutions, based on the calculated humidity value H 计算 Controlling the operation of the dehumidifier specifically includes: before the start of the target time period t, using a humidity sensor to detect and obtain the measured humidity H of the environment in which the dehumidifier is located. 实测; Calculate and obtain the calculated humidity value H 计算 and measured humidity H 实测 The absolute value of the difference between them |ΔH 计算-实测 |;Based on the absolute value of the difference|ΔH 计算-实测 | To control the operation of the dehumidifier.

[0023] Compared with existing technologies, the technical effect achieved by this technical solution is: deviation threshold ΔH 阈 The allowable error range for the humidity sensor is defined as follows: if the absolute value of the difference is |ΔH 计算-实测 | Less than the deviation threshold ΔH 阈 If the humidity sensor has a smaller error, the dehumidifier can operate according to the target dehumidification mode.

[0024] In any of the above technical solutions, based on the absolute value of the difference |ΔH 计算-实测 |, controlling the operation of the dehumidifier, specifically including: when the dehumidifier is turned on, controlling the dehumidifier to execute the target dehumidification mode; when the absolute value of the difference is |ΔH 计算-实测 |Greater than the deviation threshold ΔH 阈 In this case, control the dehumidifier to increase the fan speed and / or extend the execution time of the target dehumidification mode based on the target dehumidification mode.

[0025] Compared with existing technologies, the technical effects achieved by adopting this technical solution are: absolute value of the difference |ΔH 计算-实测 |Greater than the deviation threshold ΔH 阈 If the humidity sensor has a large error, the wind speed should be increased and / or the execution time of the target dehumidification mode should be extended to reduce the error, so that the ambient humidity can reach the user's expected value and improve the user experience.

[0026] To achieve the second objective of this invention, the present invention provides a control device for a dehumidifier, comprising: a flow meter, the flow meter being used to continuously detect the real-time flow rate F of the dehumidifier at various time points within a target time period t. 实时 Temperature sensor; the temperature sensor is used to detect the ambient temperature T of the environment in which the dehumidifier is located. 环境 The water removal volume calculation module is used to calculate the water removal volume based on the real-time flow rate F. 实时 The system obtains the amount of water removed by the dehumidifier, W, within a target time period t; a humidity calculation module is used to calculate the humidity value based on the amount of water removed, W, and the ambient temperature, T. 环境 Determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 The control module is used to calculate the humidity value H. 计算 Control the operation of the dehumidifier.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0038] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the following description is provided in conjunction with... Figure 1 Specific embodiments of the present invention will be described in detail below.

[0039]

Example 1

[0040] like Figure 1 As shown, an embodiment of the present invention provides a control method for a dehumidifier, the control method comprising: continuously detecting the real-time flow rate F of the dehumidifier at each time point within a target time period t. 实时 And detect the ambient temperature T of the environment where the dehumidifier is located. 环境 According to real-time traffic F 实时 Obtain the amount of water removed by the dehumidifier W within the target time period t; based on the amount of water removed W and the ambient temperature T... 环境 Determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 Based on the calculated humidity value H 计算 Control the operation of the dehumidifier.

[0041] In related technologies, most dehumidifiers use humidity sensors to detect the humidity of the surrounding environment. The humidity sensor obtains the relative humidity of the environment by measuring the voltage drop across a humidity-sensitive resistor. However, if the humidity sensor is located near the water tank or air duct, the humidity in a certain area of ​​the user's home is high, or the room is large, relying solely on the humidity sensor's detection will not provide an accurate overall humidity reading for the room.

[0042] In view of this, the present invention provides a control method for a dehumidifier, which controls the opening and closing of the dehumidifier by improving the accuracy of ambient humidity detection, so as to reduce the situation of premature shutdown due to humidity sensor error.

[0043] Specifically, the dehumidifier of the present invention is equipped with a flow meter, which is used to detect the real-time flow rate F. 实时 via F 实时 The amount of water removed by the dehumidifier W within a period t can be calculated, and the calculated humidity value H of the surrounding environment can be obtained from the amount of water removed W. 计算 The dehumidifier calculates the humidity value H. 计算 This is used to determine whether to stop the dehumidifier. Since air humidity has a certain standard, the calculated humidity value H is obtained by calculating the dehumidifier's water removal capacity W. 计算 The results are relatively accurate, with a small error compared to the actual ambient humidity. This is achieved by calculating the humidity value H. 计算 This control method can effectively prevent the dehumidifier from shutting down prematurely due to errors in the humidity sensor when the dehumidification environment is complex or the space is too large, thus providing users with a better user experience.

[0044] Preferably, each specific dehumidifier has a corresponding dehumidification capacity rating. When the dehumidifier is turned on, the device uses temperature and humidity sensors to obtain the current temperature and humidity values ​​in the environment. At the same time, as the device runs, the flow meter continuously counts the amount of water removed per unit time (W) by measuring the amount of water removed, which can be used to calculate the relative humidity in the environment.

[0045] Preferably, the real-time traffic F within period t 实时 You can first read the instantaneous flow rate at a certain moment, and then read it again after a period t. The difference between the two readings is the real-time flow rate F within period t. 实时 The optimal period t is 3-6 minutes, during which the calculated humidity value H is obtained. 计算 The dehumidifier operates well under control.

[0046] In some embodiments of the present invention, the water removal capacity W is calculated using formula (I):

[0047] Where π is the mathematical constant pi, t0 is the start time of period t, t1 is the end time of period t, and f(t) is a function relating time and flow velocity.

[0048] Preferably, the amount of water removed by the dehumidifier within a period t can be calculated using equation (I) to obtain the ambient humidity where the dehumidifier is located. Since all values ​​in equation (I) are readily available, calculating the amount of water removed W is relatively easy. The amount of water removed is the amount of moisture removed from the air by the dehumidifier during continuous operation within a period t. The start time of period t is t0, and the end time is t1, which is the amount of water removed.

[0049]

[0050] In some embodiments of the present invention, based on the water removal rate W and the ambient temperature T 环境 Determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 Specifically, this includes: obtaining the initial humidity value H of the environment where the dehumidifier is located at the start of the target time period t. 起始 Based on the water removal capacity W and the ambient temperature T 环境 Determine the humidity change ΔH of the environment in which the dehumidifier is located within the target time period t; based on the initial humidity value H... 起始 The difference between the humidity change value ΔH and the humidity change value ΔH is used to determine the calculated humidity value H of the environment where the dehumidifier is located. 计算 Among them, the initial humidity value H 起始 The value is the relative humidity obtained using a humidity sensor.

[0051] Preferably, the initial humidity value H 起始 A humidity sensor is used for detection, and the humidity sensor detects H. 起始 The relative humidity value is obtained by using a humidity sensor. The initial humidity H is relatively accurate and easy to obtain.

[0052] Preferably, the humidity sensor is a sensor that converts the humidity in the environment into an electrical signal output sensor. The humidity sensor utilizes the charge carriers - holes or electrons in the grains of sintered humidity-sensitive semiconductor ceramic material. When water molecules are adsorbed on its surface, it will cause a change in the resistivity of the surface and grain interface, thus exhibiting humidity-sensitive characteristics.

[0053] Preferably, during operation, the dehumidifier continuously removes moisture from the air, causing a change in the humidity of the environment in which the dehumidifier operates. This change occurs after the initial humidity value H has been measured by a humidity sensor. 起始 In this case, only the initial humidity value H is needed. 起始 The calculated humidity value H of the environment in which the dehumidifier is located is determined by subtracting the humidity change value ΔH from the humidity change value. 计算 This gives the calculated humidity value H of the environment in which the dehumidifier is located. 计算The results are relatively accurate, effectively avoiding the detection error of the humidity sensor when the dehumidification environment is complex or the space is too large.

[0054] In some embodiments of the present invention, based on the water removal rate W and the ambient temperature T 环境 Determine the humidity change ΔH of the environment in which the dehumidifier is located within the target time period t. Specifically, this includes: looking up the value of the humidity change ΔH in the absolute humidity and relative humidity correspondence table at ambient temperature T. 环境 Below, the absolute humidity value ρ is consistent with the value of the water removal capacity W. ω In the table of absolute humidity and relative humidity, find the value corresponding to the absolute humidity ρ. ω The corresponding relative humidity value RH is used, and the relative humidity value RH is used as the humidity change value ΔH.

[0055] Preferably, since ambient humidity has certain standards, after a certain amount of moisture is removed from the environment by the dehumidifier, the humidity still follows the standard for air humidity, and its value can be determined. Therefore, knowing the humidity change ΔH, the calculated humidity value H of the environment where the dehumidifier is located can be obtained. 计 Calculate.

[0056] Preferably, the initial humidity value H measured by the humidity sensor is... 起始 For relative humidity, therefore, it is the same as the initial humidity value H. 起始 Correspondingly, the humidity change value ΔH should also be converted into relative humidity, based on the water removal capacity W and the ambient temperature T. 环境 By referring to the absolute humidity and relative humidity correspondence table, the humidity change value ΔH can be obtained, thus yielding the calculated humidity value H of the environment where the dehumidifier is located. 计算 .

[0057] In some embodiments of the present invention, the humidity value H is calculated. 计算 Controlling the operation of the dehumidifier specifically includes: determining the target humidity H of the environment in which the dehumidifier is located when it is turned on. 目标 ; In calculating the humidity value H 计算 Achieve target humidity H 目标 In such cases, control the dehumidifier to stop.

[0058] Preferably, the user sets a target humidity H before turning on the dehumidifier. 目标 Target humidity H 目标 This refers to the humidity level that the user expects the environment to reach after the dehumidifier is running; the humidity value H is calculated. 计算 The humidity of the environment is calculated by the dehumidifier based on the water removal capacity W. When the calculated humidity value H... 计算 Achieve target humidity H 目标 At this point, the error between the ambient humidity and the target humidity is small, resulting in a good dehumidification effect.

[0059] It should be noted that the calculated humidity value H mentioned here... 计算 Achieve target humidity H 目标 It is not about calculating the humidity value H. 计算 With target humidity H 目标 The humidity levels are not exactly equal, but an error of 0%-3% is allowed. However, since the error range is small, it has little impact on the actual humidity perceived by the user. In this case, the dehumidifier will not affect the user's actual experience when it stops.

[0060] In some embodiments of the present invention, the humidity value H is calculated. 计算 Controlling the operation of the dehumidifier specifically includes: before the start of the target time period t, using a humidity sensor to detect and obtain the measured humidity H of the environment in which the dehumidifier is located. 实测 ; Calculate and obtain the calculated humidity value H 计算 and measured humidity H 实测 The absolute value of the difference between them |ΔH 计算-实测 |;Based on the absolute value of the difference|ΔH 计算-实测 | To control the operation of the dehumidifier.

[0061] Preferably, the dehumidifier is turned on and run for 3-5 minutes before the start of cycle t, and then the measured humidity H of the environment in which the dehumidifier is located is measured using a humidity sensor. 实测 The humidity value H is calculated based on the ambient humidity obtained from the water removal capacity W. 计算 The target humidity H is calculated. 目标 and measured humidity H 实测 The absolute value of the difference between them |ΔH 计算-实测 |, through the absolute value of the difference|ΔH 计算-实测 This can determine whether the humidity sensor's detection results are accurate, thus eliminating the possibility of errors in the humidity sensor.

[0062] Preferably, if the absolute value of the difference is |ΔH 计算-实测 If the value is small, the humidity sensor has no error or the error is minimal; in this case, the measured humidity H read by the humidity sensor can still be used as the standard. 实测 To control the operation of the dehumidifier; if the absolute value of the difference is |ΔH 计算-实测 If the value is too small, the humidity sensor will have a larger error. In this case, the calculated humidity value H obtained based on the water removal capacity W will be larger. 计算 To control the operation of the dehumidifier.

[0063] In some embodiments of the present invention, based on the absolute value of the difference |ΔH 目标-实测 |, controlling the operation of the dehumidifier, specifically including: when the dehumidifier is turned on, controlling the dehumidifier to execute the target dehumidification mode; when the absolute value of the difference is |ΔH 计算-实测 | Less than the deviation threshold ΔH 阈In this case, the dehumidifier will continue to execute the target dehumidification mode.

[0064] Preferably, the deviation threshold ΔH 阈 The allowable error range for the humidity sensor is defined as follows: if the absolute value of the difference is |ΔH 计算-实测 | Less than the deviation threshold ΔH 阈 If the humidity sensor has a smaller error, the dehumidifier can operate according to the target dehumidification mode.

[0065] Preferably, in the target dehumidification mode, the dehumidifier operates according to the measured humidity H detected by the humidity sensor. 实测 To control the operation of the dehumidifier, when the humidity sensor detects the measured humidity H... 实测 Achieve target humidity H 目标 The dehumidifier stops.

[0066] In some embodiments of the present invention, based on the absolute value of the difference |ΔH 计算-实测 |, controlling the operation of the dehumidifier, specifically including: when the dehumidifier is turned on, controlling the dehumidifier to execute the target dehumidification mode; when the absolute value of the difference is |ΔH 计算-实测 |Greater than the deviation threshold ΔH 阈 In this case, control the dehumidifier to increase the fan speed and / or extend the execution time of the target dehumidification mode based on the target dehumidification mode.

[0067] Preferably, the absolute value of the difference |ΔH 计算-实测 |Greater than the deviation threshold ΔH 阈 If the humidity sensor fails to detect the actual humidity H, then the humidity sensor will have a significant error and will no longer reflect the measured humidity H. 实测 Instead of controlling the operation of the dehumidifier, it is based on the calculated humidity value H. 计算 To control the operation of the dehumidifier, the fan speed should be increased and / or the execution time of the target dehumidification mode should be extended to reduce errors and ensure that the ambient humidity reaches the target humidity H. 目标 This is to meet the needs of rent-free users and improve user experience.
