Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and in particular to a control method and device for the humidification wheel of a purifier, a purifier, and a storage medium. Background Technology

[0002] With the progress of the times and the development of science and technology, people's living standards have gradually improved, and people have higher demands for air quality. Single-function air purifiers or humidifiers can no longer meet people's needs. In order to minimize the harm of environmental pollutants to the human body while regulating environmental humidity and improving human comfort, humidifiers that combine humidification and air purification have emerged.

[0003] Currently, evaporative humidifiers primarily humidify the air by rotating a humidifying wheel to drive a evaporative curtain, which in turn is blown into the air by a fan. Generally, the humidifying wheel operates at a constant speed, and the torque it exerts on the evaporative curtain is also constant. However, this often leads to uneven wetting of the evaporative curtain, resulting in varying weights due to differences in moisture content. If the weight of a certain part of the evaporative curtain exceeds the constant torque of the humidifying wheel, the curtain will not rotate; conversely, if the weight is much less than the constant torque, the curtain will experience a momentary rapid rotation, resulting in inconsistent rotation speeds. Summary of the Invention

[0004] This invention proposes a control method and device for the humidification wheel of an air purifier, as well as an air purifier and a storage medium, to solve the technical problem in the prior art where uneven wetting of the evaporative cooling pad causes the rotation process of the evaporative cooling pad to be sometimes fast and sometimes slow.

[0005] One aspect of the present invention provides a method for controlling the humidification wheel of a purifier, the method comprising:

[0006] When the evaporative air purifier's wet curtain enters its first rotation cycle, the humidifying wheel is controlled to drive the wet curtain to rotate at a preset initial speed.

[0007] During the process of the humidifying wheel driving the wet curtain to rotate, the initial speed is adjusted to the preset minimum speed;

[0008] The humidifying wheel is controlled to drive the wet curtain to rotate at the minimum speed until the humidification time of the wet curtain reaches one rotation cycle.

[0009] Furthermore, after the humidification time of the wet curtain reaches one rotation cycle, the method further includes:

[0010] During the process of the humidifying wheel driving the wet curtain to rotate, the minimum speed is adjusted to the target speed of the humidifying wheel, and the humidifying wheel is controlled to drive the wet curtain to rotate at the target speed.

[0011] Furthermore, the step of controlling the humidifying wheel to drive the evaporative cooling pad to rotate at a preset initial speed when the evaporative cooling pad enters its first rotation cycle includes:

[0012] When the purifier turns on the humidification function, the humidification wheel is powered on, and the humidification time of the wet curtain is acquired and recorded in real time.

[0013] Based on the humidification duration, it is determined whether the monitoring has entered and is in the first rotation cycle, so that when the wet curtain enters the first rotation cycle, the humidification wheel is controlled to drive the wet curtain to rotate at the initial speed.

[0014] Furthermore, adjusting the initial rotation speed to a preset minimum rotation speed during the process of the humidifying wheel driving the wet curtain to rotate includes:

[0015] The initial speed is adjusted by a unit speed reduction adjustment using the first acceleration;

[0016] Determine whether the speed after the speed reduction adjustment is less than or equal to the minimum speed;

[0017] If the adjusted rotational speed is greater than the minimum rotational speed, the current rotational speed will continue to be reduced by the first acceleration until the adjusted rotational speed is less than or equal to the minimum rotational speed, wherein the first acceleration a = N1 / T, N1 is the unit adjustment rotational speed, and T is the preset rotational speed adjustment running time.

[0018] Furthermore, adjusting the minimum rotation speed to the target rotation speed of the humidifying wheel during the rotation of the humidifying wheel and the wet curtain includes:

[0019] The minimum speed is adjusted by accelerating the speed adjustment unit by using the first acceleration.

[0020] Determine whether the adjusted engine speed is greater than or equal to the target engine speed;

[0021] If the adjusted rotational speed is less than the target rotational speed, the current rotational speed is further accelerated by the first acceleration until the adjusted rotational speed is greater than or equal to the target rotational speed.

[0022] Furthermore, the method also includes:

[0023] When the purifier turns off the humidification function, determine whether the current rotation speed of the humidification wheel is less than or equal to the minimum rotation speed;

[0024] If the current rotation speed of the humidifying wheel is less than or equal to the minimum rotation speed, the rotation speed of the humidifying wheel will be reduced to 0 directly, and the power supply to the humidifying wheel will be turned off.

[0025] Furthermore, the method also includes:

[0026] The recorded humidification duration data of the wet curtain is reset to zero.

[0027] Furthermore, the method also includes:

[0028] If the current rotation speed of the humidifying wheel is greater than the minimum rotation speed, the current rotation speed is reduced. It is then determined whether the adjusted rotation speed is less than or equal to the minimum rotation speed. If the adjusted rotation speed is greater than the minimum rotation speed, the current rotation speed is further reduced by one unit rotation speed until the adjusted rotation speed is less than or equal to the minimum rotation speed.

[0029] In another aspect, the present invention provides a control device for a humidifier wheel of an air purifier, the device comprising a functional module for implementing the control method for the humidifier wheel of an air purifier as described above.

[0030] A third aspect of the present invention provides an air purifier, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the control method for the humidifying wheel of the air purifier as described above.

[0031] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the steps of the control method for the humidifier wheel of the purifier as described above.

[0032] This invention discloses a control method and device for the humidification wheel of an air purifier, along with the air purifier and storage medium. By monitoring the humidification switch status and humidification duration, the working state of the humidification wheel is controlled to ensure that the evaporative cooling pad is fully saturated during the first rotation. This effectively solves the problem of uneven humidification of the evaporative humidifier cooling pad, which causes inconsistent rotation speeds due to varying moisture content in different parts, thus ensuring a superior user experience. Furthermore, the humidification wheel's operation is controlled in stages and steps, adapting to different working states during humidification and ensuring stable operation of the cooling pad while balancing the effective humidification output.

[0039] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. Obviously, the described embodiments are only a portion, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] Figure 1 A flowchart illustrating a control method for a humidifier wheel in an air purifier according to an embodiment of the present invention is shown. Figure 1 As shown, the control method for the humidifying wheel of the air purifier proposed in this embodiment of the invention includes the following steps:

[0041] S11. When the evaporative air purifier's evaporative air curtain enters its first rotation cycle, control the humidifying wheel to drive the evaporative air curtain to rotate at a preset initial speed.

[0042] In this embodiment of the invention, an evaporative humidifier purifier is used as an example for explanation and illustration.

[0043] Specifically, the humidification time of the wet curtain can be compared with the time it takes for the wet curtain to rotate once to determine whether the wet curtain has entered and is in its first rotation cycle.

[0044] S12. During the process of the humidifying wheel driving the wet curtain to rotate, the initial speed is adjusted to the preset minimum speed;

[0045] S13. Control the humidifying wheel to drive the wet curtain to rotate at the minimum speed until the humidification time of the wet curtain reaches one rotation cycle.

[0046] In this embodiment, during the humidification stage of the first rotation cycle of the wet curtain, the humidification wheel is controlled to drive the wet curtain to rotate at a preset minimum speed until the humidification time of the wet curtain reaches one rotation cycle. This allows the wet curtain to be fully soaked in the first rotation, extending the time that each part of the wet curtain is immersed in water, thus achieving the effect of fully soaking the wet curtain. This effectively solves the problem of uneven wetting of the wet curtain during the humidification process of evaporative humidifiers, ensuring that the wet curtain is fully and evenly soaked.

[0047] Figure 2 A flowchart illustrating a control method for a humidifier wheel in a purifier according to another embodiment of the present invention is shown. Figure 2 As shown, the control method for the humidifying wheel of the air purifier proposed in this embodiment of the invention includes the following steps:

[0048] S11. When the evaporative air purifier's evaporative air curtain enters its first rotation cycle, control the humidifying wheel to drive the evaporative air curtain to rotate at a preset initial speed.

[0049] S12. During the process of the humidifying wheel driving the wet curtain to rotate, the starting speed is adjusted to the preset minimum speed.

[0050] S13. Control the humidifying wheel to drive the wet curtain to rotate at the minimum speed until the humidification time of the wet curtain reaches one rotation cycle.

[0051] S14. During the process of the humidifying wheel driving the wet curtain to rotate, the minimum speed is adjusted to the target speed of the humidifying wheel, and the humidifying wheel is controlled to drive the wet curtain to rotate at the target speed.

[0052] Specifically, when the humidification time of the wet curtain reaches one rotation cycle, the rotation speed of the humidification wheel is adjusted to the target rotation speed of the humidification wheel during the rotation of the wet curtain driven by the humidification wheel, so as to meet the humidification requirements.

[0053] The humidification wheel control method for air purifiers proposed in this invention monitors the humidification switch status and humidification duration to control the working state of the humidification wheel. This ensures that the evaporative cooling pad is fully saturated during the first rotation, effectively solving the problem of inconsistent rotation speed of the evaporative humidification air purifier due to uneven wetting and varying moisture content in different parts. This ensures a superior user experience. Furthermore, the humidification wheel's operation is controlled in stages and steps, adapting to different working states during humidification and ensuring stable operation of the evaporative cooling pad while balancing the effective humidification output.

[0054] In this embodiment of the invention, step S11, which involves controlling the humidifying wheel to rotate the evaporative cooling pad at a preset initial rotation speed when the evaporative cooling pad enters its first rotation cycle, specifically includes: when the purifier turns on its humidification function, turning on the power to the humidifying wheel and acquiring and recording the humidification duration of the evaporative cooling pad in real time; determining whether the evaporative cooling pad has entered and is in its first rotation cycle based on the humidification duration, so as to control the humidifying wheel to rotate the evaporative cooling pad at the initial rotation speed when the evaporative cooling pad enters its first rotation cycle.

[0055] In this embodiment of the invention, step S12, which involves adjusting the initial rotation speed to a preset minimum rotation speed during the rotation of the humidifying wheel and the wet curtain, specifically includes: adjusting the initial rotation speed by decreasing the speed by a first acceleration; determining whether the speed after the speed reduction adjustment is less than or equal to the minimum rotation speed; if the adjusted speed is greater than the minimum rotation speed, then continuing to adjust the current speed by decreasing the speed by a first acceleration by a unit of the first acceleration until the adjusted speed is less than or equal to the minimum rotation speed.

[0056] Wherein, the first acceleration a = N1 / T, N1 is the unit adjustment speed, and T is the preset speed adjustment running time.

[0057] In this embodiment of the invention, step S13, adjusting the minimum rotation speed to the target rotation speed of the humidifying wheel during the rotation of the humidifying wheel and the wet curtain, specifically includes: accelerating the minimum rotation speed by adjusting the unit rotation speed with a first acceleration; determining whether the adjusted rotation speed is greater than or equal to the target rotation speed; if the adjusted rotation speed is less than the target rotation speed, then continuing to accelerate the current rotation speed by adjusting the unit rotation speed with the first acceleration until the adjusted rotation speed is greater than or equal to the target rotation speed.

[0058] In this embodiment of the invention, when the purifier turns off the humidification function, it first determines whether the current rotation speed of the humidification wheel is less than or equal to the minimum rotation speed. If the current rotation speed of the humidification wheel is less than or equal to the minimum rotation speed, the rotation speed of the humidification wheel is directly reduced to 0, and the power to the humidification wheel is turned off. Further, the recorded humidification duration data of the wet curtain is cleared. If the current rotation speed of the humidification wheel is greater than the minimum rotation speed, the current rotation speed is reduced. It is then determined whether the adjusted rotation speed is less than or equal to the minimum rotation speed. If the adjusted rotation speed is greater than the minimum rotation speed, the current rotation speed is further reduced by a unit adjustment speed until the adjusted rotation speed is less than or equal to the minimum rotation speed. Specifically, during the reduction adjustment, a first acceleration can be used for the reduction.

[0059] The technical solution of the present invention will be clearly explained and illustrated below through a specific embodiment.

[0060] like Figure 3As shown, the current operating speed (n) of the humidifying wheel is controlled according to the humidifying switch state and the humidifying duration (t). When the humidifying wheel is initially turned on, it rotates the wet curtain at a low speed for one week, increasing the time for each part of the wet curtain to be immersed in water, achieving the effect of fully wetting the wet curtain, and then resumes the target speed for continuous humidification. The specific implementation process is as follows:

[0061] 1. Execute the steps of running or stopping the humidifying wheel according to the humidifying switch state;

[0062] 2. Running steps:

[0063] a. Compare the size of the humidifying duration (t) and the duration (T1) for the wet curtain to rotate one week, and determine the humidifying situation:

[0064] ① If t < T1, that is, the wet curtain has not been wetted at a low speed for one week, start from step b;

[0065] ② If t ≥ T1, that is, the wet curtain has been fully wetted, start from step g.

[0066] b. Turn on the power of the humidifying wheel;

[0067] c. The humidifying wheel starts at the starting speed (N , 目 , , min , , , , , ,

[0076] ,

[0071] , 目 , min ,

[0075] ,

[0074] ,

[0073] ,

[0077] ,

[0072] )

[0068] d. Adjust the current operating speed (n) of the humidifying wheel to the lowest speed (N min ) with the first acceleration, where the first acceleration a = N1 / T, N1 is the unit adjustment speed, and T is the preset speed adjustment operation time:

[0069] ① If n > N min , the speed of the humidifying wheel is reduced by N1 and step d is repeated;

[0070] ② If n ≤ N min , the speed of the humidifying wheel remains unchanged and step e is started.

[0071] e. The humidifying wheel runs at N​​​​​​​​​​​​​​​​​​​​​​​②If n≥N 目 If the humidifying wheel speed remains unchanged, the process will start from step h.

[0078] h. Humidifier wheel with N 目 run.

[0079] 3. Stopping procedure:

[0080] a. Reduce the speed of n to 0:

[0081] ①If n>N min Then the humidifier wheel speed is reduced by N1 and step a is repeated;

[0082] ②If n≤N min If so, the humidifier wheel speed will drop directly to 0 and execution will start from step b.

[0083] b. Turn off the power to the humidifier wheel;

[0084] c. Clear t.

[0085] The above running or stopping steps are repeated every certain period of time (T).

[0086] In this specific embodiment:

[0087] The unit adjustment speed N1 can be 0.5-1 r / min, and can be adjusted according to the difference between the minimum speed and the target speed.

[0088] Starting speed N 初 A speed of 3-6 r / min is acceptable.

[0089] Minimum speed N min A speed of 1-2 r / min is acceptable;

[0090] Time taken for the evaporative cooling pad to complete one rotation: T1 = (1r / N) min *Gear acceleration or deceleration factor: If there is gear acceleration or deceleration at the connection between the humidifying wheel and the evaporative cooling pad, the corresponding factor conversion is required. For example, if the number of teeth on the humidifying wheel at the connection point is three times more than the number of teeth on the evaporative cooling pad, there is a 3x gear acceleration relationship. If N min If we take 1 r / min, then T1 = (1 r / 1(r / min)) * 3 = 3 min.

[0091] The running time T can be 0.1-10 seconds, and can be adjusted according to actual needs.

[0092] During operation, the evaporative humidifier purifier controls the humidifying wheel in stages and steps, thereby affecting the rotation of the wet curtain. This effectively avoids the problem of uneven wet curtain rotation caused by the difference in moisture content in different parts of the wet curtain, which leads to an imbalance between the weight of the wet curtain and the rotational torque of the humidifying wheel. This ensures a superior user experience.

[0093] For the sake of simplicity, the method embodiments are described as a series of actions. However, those skilled in the art should understand that the embodiments of the present invention are not limited to the described order of actions, because according to the embodiments of the present invention, some steps can be performed in other orders or simultaneously. Furthermore, those skilled in the art should also understand that the embodiments described in the specification are preferred embodiments, and the actions involved are not necessarily essential to the embodiments of the present invention.

[0104] In this embodiment of the invention, the speed adjustment module 202 is also used to determine whether the current rotation speed of the humidifying wheel is less than or equal to the minimum rotation speed when the purifier turns off the humidification function; if the current rotation speed of the humidifying wheel is less than or equal to the minimum rotation speed, the rotation speed of the humidifying wheel is directly reduced to 0.

[0105] Furthermore, the control module 201 is also used to turn off the power supply to the humidifying wheel and clear the recorded humidification duration data of the wet curtain.

[0106] Furthermore, the speed adjustment module 202 is specifically used to reduce the speed of the current rotational speed if the current rotational speed of the humidifying wheel is greater than the minimum rotational speed, determine whether the speed after the speed reduction adjustment is less than or equal to the minimum rotational speed, and if the adjusted speed is greater than the minimum rotational speed, continue to reduce the speed of the current rotational speed by a unit adjustment speed until the adjusted speed is less than or equal to the minimum rotational speed.
