Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The following exemplary described embodiments do not represent all embodiments consistent with the present disclosure. Rather, they are merely examples of devices consistent with certain aspects of the present disclosure as recited in the claims below. It should be noted that, in the following examples and embodiments, features may be combined with each other without conflict.
In order to solve the technical problem, the embodiment of the present disclosure provides a method for detecting a filter screen of an indoor unit of a fresh air conditioner, which can be applied to a fresh air conditioner. The indoor unit of the fresh air conditioner is internally provided with a fresh air duct, namely an air inlet passage and an air outlet passage, and a fresh air fan is arranged in the air inlet passage, wherein the fresh air fan can comprise a fan and a motor in one example. The motors may include an internal motor (also called a low-voltage motor, such as a 12V motor) and an external motor (also called a high-voltage motor, such as a 310V motor), the internal motor is a motor with a control portion inside, and the external motor is a motor with a control portion outside. Particularly, the treater is located the inside or outside of new trend fan in this disclosure, does not all influence the implementation of this disclosed scheme.
Taking a 12V motor as an example, the motor may include 4 terminals: the motor comprises a positive end (inputting 12V voltage), a negative end (GND, grounded to form a current loop), a control end (VSP, inputting control voltage, such as 0-5V, the rotating speed is faster when the voltage is larger) and a feedback end (FG, feeding back different frequencies to reflect the rotating speed of the motor). And, the processor may communicate with the motor, output a control signal to the motor, so as to make the motor work in different working states, for example, a first preset working state or a second preset working state, and then detect whether the filter screen is installed. Taking the 310V motor as an example, the motor may include 3 terminals: u-phase terminal, V-phase terminal and W-phase terminal. At this time, the power module in the fresh air conditioner can convert an external power supply into 310V direct current, and the 310V direct current is respectively input into 3 terminals of the motor through a switch device (such as an MOS switch tube or an IGBT device) so as to supply power to the fresh air motor. For convenience of understanding, in the following embodiments, the motor of the fresh air fan is a 12V motor as an example to describe various schemes, but the present disclosure is not limited thereto.
Fig. 1 is a flowchart illustrating a method for detecting a filter screen of a fresh air conditioning indoor unit according to an exemplary embodiment, where the fresh air conditioning indoor unit includes a fresh air duct, and a fresh air blower is disposed in the fresh air duct, and referring to fig. 1, the method for detecting a filter screen of a fresh air conditioning indoor unit includes steps 11 to 13.
In step 11, after a fresh air fan in the fresh air conditioner is controlled to work for a first set time under a first preset condition, first working data of the fresh air fan is obtained.
In this embodiment, the processor of the indoor unit of the fresh air conditioner may send a first control signal to the fresh air blower, where the first control signal is a voltage signal of 1V, so as to control the fresh air blower to operate under a first preset condition for a first set time. The first preset condition is that the expected rotating speed of the fresh air fan is a first rotating speed, and if the first rotating speed is 200 revolutions per minute. The first set time period is 10 seconds.
It should be noted that, because the first control signal is set in the fresh air duct, the processor sends the first control signal to control the fresh air fan to operate at an expected rotation speed, but there may be some reasons that the actual rotation speed of the fresh air fan is not matched with the expected rotation speed, for example, the shape and the opening of the fresh air duct may cause the actual rotation speed to slightly deviate from the expected rotation speed (for example, more than or less than several rotations, tens of rotations, etc.), which is a normal error and can be ignored. If no filter screen is installed in the fresh air duct, the actual rotation speed is much less than the expected rotation speed (e.g. the difference is 100 and 200 rpm), which is a problem to be solved by the scheme of the present disclosure.
It should be noted that the setting of the first duration aims to enable the fresh air fan to be in a stable working state, so the first duration may be set according to a specific scene, and is not limited herein.
In this embodiment, the processor may further obtain first working data of the fresh air blower. Wherein the first working data may include at least one of: the motor current of the fresh air fan and the rotating speed of the fresh air fan.
Taking the first working data as the motor current of the fresh air fan as an example, the indoor unit of the fresh air conditioner is provided with a power supply module under the scene, and the power supply module can provide voltage and current for the fresh air fan. After the fresh air fan works for a first set time under a first preset condition, the processor can communicate with the power supply module to obtain the current output by the power supply module, namely the motor current of the fresh air fan, and the current is used as first working data.
It should be noted that, the fresh air conditioning indoor unit may further be provided with a current detection module, for example, a precision resistor (for example, a resistance value of 10 ohms) is connected in series between a negative electrode end of the motor in the fresh air blower and the ground, and the current detection module may obtain voltages at two ends of the precision resistor, calculate a current flowing through the precision resistor according to the voltage and the resistance value of the precision resistor, and use the current as the first working data of the fresh air blower. Technicians can select a mode for acquiring the first working data according to specific scenes, and the corresponding scheme falls into the protection scope of the disclosure.
Taking the first working data as the rotating speed of the fresh air fan as an example, the processor of the fresh air conditioner indoor unit can communicate with the feedback end of the motor in the fresh air fan under the scene to acquire the frequency output by the feedback end. In this scenario, a corresponding relation table of frequency and rotation speed can be stored in the fresh air conditioner indoor unit, and the processor can query the corresponding relation table after acquiring the frequency output by the feedback end to obtain the rotation speed corresponding to the frequency; and the rotating speed is used as first working data of the fresh air fan.
It should be noted that, in consideration of the scene of whether the filter screen is installed or not, the current of the fresh air fan at a low rotation speed (such as 700 rpm) changes greatly, that is, the resistance is large when the filter screen is installed, so that the current of the fresh air fan at the same rotation speed is large; and when the filter screen is not installed, the resistance is smaller, so that the current of the fresh air fan at the same rotating speed is smaller. Thus, in one example, the processor may use the current of the fresh air fan at a low speed as the first operating data.
In step 12, after the new air blower is controlled to work for a second set time under a second preset condition, second working data of the new air blower is obtained.
In this embodiment, the processor of the fresh air conditioning indoor unit may send a second control signal to the fresh air blower, where the second control signal is a voltage signal of 5V, so as to control the fresh air blower to operate under a second preset condition. Wherein the second preset condition is: the expected rotating speed of the fresh air fan is the second rotating speed, and the value range of the second rotating speed is 2000 and 2700 revolutions per minute. The second time period is 10 seconds. The setting purpose of the second time length is the same as that of the first time length, and the setting can be carried out according to specific scenes under the condition that the fresh air fan is in a stable working state, and is not limited here.
It should be noted that, because the second control signal is set in the fresh air duct, the processor sends the second control signal to control the fresh air fan to operate at an expected rotation speed, but there may be some reasons that the actual rotation speed of the fresh air fan is not matched with the expected rotation speed, for example, the shape and the opening of the fresh air duct may cause the actual rotation speed to slightly deviate from the expected rotation speed (for example, more than or less than several rotations, tens of rotations, etc.), which is a normal error and can be ignored. If no filter screen is installed in the fresh air duct, the actual rotating speed is far less than the expected rotating speed (if the difference is hundreds of revolutions per minute), which is the problem to be solved by the scheme disclosed by the invention.
It should be noted that the second rotation speed is related to the rated power or the maximum power of the motor in the fresh air blower, for example, 0.9 times of the corresponding rotation speed at the maximum power is used as the second rotation speed, for example, the maximum rotation speed of the motor is used as an expected rotation speed reached by the motor. The motor can reach above-mentioned second rotational speed when installing the filter screen in the new trend wind channel, then can't reach above-mentioned second rotational speed when not installing the filter screen.
In this embodiment, the fresh air conditioner indoor unit can also acquire second working data of the fresh air fan. Wherein the second working data may include at least one of: the motor current of the fresh air fan and the rotating speed of the fresh air fan.
When the second working data is the motor current of the fresh air fan, reference may be made to the process of obtaining the motor current by using the first working data in step 11, which is not described herein again.
When the second working data is the rotation speed of the fresh air fan, reference may be made to the process of obtaining the rotation speed of the first working data in step 11, which is not described herein again.
It should be noted that, in the fresh air duct of the indoor unit of the fresh air conditioner, the wind field may change without installing the filter screen, which results in the power of the fresh air blower becoming large, and the desired rotation speed (i.e., the second rotation speed) may not be achieved. In this way, whether the filter screen is installed or not is distinguished by setting the second rotating speed in the present example, the power requirement of the motor itself, that is, the motor is limited by the maximum power or the rated power without increasing the power without limitation, so that the rotating speed of the motor does not reach the expected rotating speed. Therefore, in one example, the processor may use the rotation speed of the fresh air fan after a second set duration as the second operating data.
In step 13, whether a filter screen is installed in the fresh air duct is determined according to the first working data and the second working data.
In this embodiment, after the processor in the indoor unit of the fresh air conditioner obtains the first working data and the second working data, whether the filter screen is installed in the fresh air duct or not can be determined according to the first working data and the second working data.
In one example, referring to fig. 2, in step 21, the processor may compare the first working data with a first preset data range. If the first working data is out of the first preset data range, the processor can obtain a first detection result; the first detection result represents that the working state of the fresh air fan is not matched with the working state corresponding to the first preset data range. When the first working data is the motor current, the first preset data range is 0.5-1A. When the first working data is the rotating speed of the fresh air fan, the first preset data range is 500-700 rpm.
In step 22, the processor may compare the second working data to a second predetermined data range. If the second working data is out of the second preset data range, the processor can obtain a second detection result; the second detection result represents that the working state of the fresh air fan is not matched with the working state corresponding to the preset rotating speed range. When the second working data is the motor current, the second preset data range is 1.5-2A. When the second working data is the rotating speed of the fresh air fan, the second preset data range is 2500-.
In step 23, if the first detection result and the second detection result are obtained, the processor may determine that the filter screen is not installed in the indoor unit of the fresh air conditioner. Because the working data of the fresh air fan in the working states of low rotating speed (namely, first rotating speed) and high rotating speed (namely, second rotating speed) are considered, the accuracy and reliability of determining whether to install the filter screen result can be improved through double-state judgment, and the misjudgment probability is reduced.
In an example, after step 21, if the first working data is within the first preset data range, the processor may obtain a third detection result; and the third detection result represents that the filter screen is installed on the indoor unit of the fresh air conditioner. At this point, the processor may not perform the subsequent step (e.g., step 23) or other step (e.g., step 22), thereby avoiding wasting computing resources.
In an example, after step 22, if the second working data is within the second preset data range, the processor may obtain a fourth detection result; and the fourth detection result represents that the filter screen is installed on the indoor unit of the fresh air conditioner. At this point, the processor may not perform the subsequent step (e.g., step 23) or other steps (e.g., step 21), thereby avoiding wasting computing resources.
It should be noted that, in the embodiment shown in fig. 2, step 21 and step 22 may be executed in parallel; alternatively, in the embodiment shown in fig. 2, the obtaining of the first detection result and the obtaining of the second detection result may be performed in parallel. Therefore, the scheme of the embodiment shown in fig. 2 can be applied to the working state of the fresh air conditioner indoor unit, especially to the scene with low fresh air function switching frequency.
In another example, referring to fig. 3, in step 31, the processor may compare the first working data with a first preset data range. If the first working data is outside the first preset data range, the processor may compare the second working data with the second preset data range. In step 32, when the second working data is located outside the second preset data range, the processor may determine that the filter screen is not installed in the indoor unit of the fresh air conditioner; and when the second working data is within the second preset data range, the processor can determine that the filter screen is installed on the indoor unit of the fresh air conditioner. Because the working data of the fresh air fan in the working states of low rotating speed (namely, first rotating speed) and high rotating speed (namely, second rotating speed) are considered, the accuracy and reliability of determining whether to install the filter screen result can be improved through double-state judgment, and the misjudgment probability is reduced.
It should be noted that the scheme in the embodiment shown in fig. 3 may combine the comparison process of the first working data and the second working data, and does not need to generate the detection result in the embodiment shown in fig. 2, and may be applicable to a scene with a high switching frequency of the fresh air function, or a scene of a switching process in which the indoor unit of the fresh air conditioner switches from one working mode to another working mode.
It should be noted that in the solution for describing the embodiment shown in fig. 1, it is considered that the motor normally rises from a low rotation speed to a high rotation speed, and therefore the first operation data corresponds to a low rotation speed operation state and the second operation data corresponds to a high rotation speed operation state. In practical application, the first working data may correspond to a high-rotation-speed working state and the second working data corresponds to a low-rotation-speed working state, so that the method is suitable for a scene that the motor is reduced from a high rotation speed to a low rotation speed, and the corresponding scheme also falls into the protection scope of the present disclosure.
In one embodiment, when the processor determines that the filter screen is not installed in the fresh air duct, the indoor unit of the fresh air conditioner can be controlled to stop. Or the processor can also generate fault information and display the fault information representing that the filter screen is not installed on a display screen of the fresh air conditioner indoor unit, for example, the filter screen is not installed and is required to be used after installation, so that the effect of reminding a user of timely processing the fault is achieved. In practical application, the fact that a user can control the fresh air conditioner indoor unit through the APP is taken into consideration, therefore, the processor can send the fault information to a communication module of the fresh air conditioner indoor unit, and the fault information is uploaded to the APP through the communication module. APP can show above-mentioned trouble prompt message through the mode of popup window, can reach the effect of reminding the user in time to handle the trouble equally. Of course, the processor may also push the fault notification information in a manner of corresponding mail, short message, or instant messaging software, and the corresponding scheme falls within the protection scope of the present disclosure.
In an embodiment, when the processor determines that the filter screen is installed in the indoor unit of the fresh air conditioner, the detection process is ended without generating a prompt message, so that the effect of not influencing a user is achieved.
Therefore, in the scheme provided by the embodiment of the disclosure, after the fresh air fan works for a first set time under a first preset condition, first working data of the fresh air fan can be acquired; controlling a fresh air fan to work under a second preset condition for a second set time, and then acquiring second working data of the fresh air fan; and then, determining whether a filter screen is installed in the fresh air duct or not according to the first working data and the second working data.
