step 200: determining that the fresh air motor is in an operating state, and detecting working parameters of the fresh air motor; the operating parameters include rotational speed or current.
In the embodiment of the application, the fresh air conditioner comprises a fresh air motor with constant output power, wherein the fresh air motor is used for guiding outdoor fresh air indoors; here, the magnitude of the constant output power may be set according to an actual use scenario, for example, the constant output power may be set to a maximum output power of the fresh air motor, or may be set to a certain fixed power value smaller than the maximum output power, which is not limited in the embodiment of the present application.

Here, the timing time may be preset by the running time timer, and the value of the timing time may be determined according to the actual situation, which is not limited in the embodiment of the present application; for example, 3 seconds, 5 seconds, etc. may be mentioned.
Fig. 2B is a schematic structural diagram of a fresh air motor in an operating state, referring to fig. 2B, where the fresh air conditioner includes a centrifugal fan and a filter screen in addition to the fresh air motor; the filter screen is arranged between the air inlet and the centrifugal fan, and the centrifugal fan is positioned between the air outlet and the filter screen; when the fresh air motor is in an operating state, the centrifugal fan can be driven to rotate, so that outdoor fresh air introduced from the air inlet filtered by the filter screen is introduced into a room through the air outlet.
Step 201: and determining the detection result of the filter screen in the fresh air conditioner according to the working parameter of the fresh air motor and the magnitude relation of at least one set threshold value.
In the embodiment of the application, after the working parameters of the fresh air motor are detected according to the steps, the working parameters of the fresh air motor are compared with at least one corresponding set threshold value, the size relation of the working parameters is determined, and then the detection result of the filter screen in the fresh air conditioner is determined according to the size relation.
Illustratively, the detection result of the filter screen may include any one of the following: a dirty blocking state, a normal state, a neglected loading state or a state of being not installed in place; here, the neglected loading state or the state of not being installed in place may be collectively referred to as a screen failure state. For example, when the detection result of the filter screen is determined to be a dirty state, the filter screen cleaning information is sent; and when the detection result of the filter screen is determined to be in a neglected loading state or a state of being not installed in place, transmitting filter screen fault information.
Here, the function of sending the filter screen cleaning information is to remind the user that the filter screen is dirty and blocked, and the filter screen needs to be cleaned or replaced; the function of sending the filter screen fault information is to remind a user of the filter screen fault, and whether the filter screen is installed or whether the filter screen is installed correctly needs to be checked. The manner of transmitting the two kinds of information is not limited, by way of example; for example, the transmission may be performed by lighting an indicator lamp, voice, or text display.
In this application embodiment, when confirming filter screen filth or filter screen trouble, through sending the warning message, the user of being convenient for in time does further operation to the filter screen, improves the result of use of fresh air conditioner.
Illustratively, determining the detection result of the filter screen in the fresh air conditioner according to the working parameter of the fresh air motor and the magnitude relation of at least one set threshold value may include: when the working parameter of the fresh air motor is determined to be greater than or equal to a first set threshold value, indicating that the detection result of the filter screen is in a dirty blocking state; when the working parameter of the fresh air motor is smaller than the first set threshold and larger than or equal to the second set threshold, the detection result of the filter screen is in a normal state; when the working parameter of the fresh air motor is smaller than the second set threshold and larger than or equal to the third set threshold, the detection result of the filter screen is in a neglected loading state or a state of being not installed in place.
Illustratively, the at least one set threshold may include a first set threshold, a second set threshold, and a third set threshold; the first set threshold is larger than the second set threshold, and the second set threshold is larger than the third set threshold.
Here, since the rotation speed and the current of the working parameter of the fresh air motor are positively correlated, and the two are the same in the manner of determining the detection result of the filter screen, the rotation speed of the fresh air motor is taken as an example for explanation.
In the embodiment of the application, after the fresh air motor is started, the fresh air motor is set to run at a certain rotating speed, and the rotating speed is set to be the rotating speed; after the fresh air motor is in an operation state and the operation time reaches the timing time, the detected rotating speed is the actual rotating speed; here, since the output power of the fresh air motor is constant, the rotation speed of the fresh air motor is inversely proportional to the torque; in addition, because the value range of the torque of the fresh air motor is certain, when the set rotating speed is set to be large, the actual rotating speed of the fresh air motor may be smaller than the set rotating speed; conversely, when the set rotational speed is set smaller, the actual rotational speed of the fresh air motor may be greater than the set rotational speed.
The method comprises the steps that after a fresh air motor is started, the fresh air motor is set to run according to a set rotating speed, the actual rotating speed of the fresh air motor is detected after a timing time, if the actual rotating speed is determined to be greater than or equal to a first set rotating speed, the filter screen is indicated to be dirty and blocked, the filter screen needs to be cleaned or replaced by a new filter screen, and at the moment, the fresh air motor is stopped; if the actual rotating speed is determined to be smaller than the second set threshold value, the filter screen is not installed or is not installed well, and at the moment, the operation of the fresh air motor is stopped; if the actual rotating speed is determined to be smaller than the third set threshold value, the fact that the fresh air motor fails is indicated, and at the moment, the operation of the fresh air motor is stopped; if the actual rotating speed is determined to be between the first set rotating speed and the second set rotating speed, the filter screen is normal, and at the moment, the fresh air motor continues to operate.
For example, assuming that after the fresh air motor is started, the rotation speed of the fresh air motor is set to 5000 rpm (set rotation speed), then the actual rotation speed of the fresh air motor is detected, if the detection result of the filter screen is in a neglected loading state or an in-place state, the actual rotation speed of the fresh air motor may be 2000 rpm or 1500 rpm; if the detection result of the filter screen is in a normal state, the actual rotation speed of the fresh air motor may fluctuate between 2000 rpm (the second set threshold value) to 3000 rpm (the first set threshold value). If the detection result of the filter screen is in a dirty state, the actual rotating speed of the fresh air motor may be greater than or equal to 3000 revolutions. If the motor is bad, the rotational speed may be less than 50 rpm (the third set threshold).
The principle of determining the detection result of the filter screen according to the rotation speed of the fresh air motor is described here as an example; since the output power of the fresh air motor is constant, as known from the formula p=tΩ, the rotation speed Ω of the fresh air motor and the torque T are inversely proportional under the condition that the output power P of the power fresh air motor is constant. When the filter screen is not installed or the installation is poor, the air resistance of the fresh air motor is reduced, the air inlet is increased, at the moment, the moment T is increased, and the rotation speed omega of the fresh air motor is reduced because the output power P is constant; on the contrary, under the condition that the filter screen of the fresh air motor is dirty and blocked, the air inlet is reduced, the air resistance is increased, the air inlet is reduced, at the moment, the moment T is reduced, and the rotation speed omega of the fresh air motor is increased because the output power P is constant. Therefore, the detection result in the fresh air conditioner can be determined by detecting the rotating speed of the fresh air motor.
Fig. 2C is a schematic diagram of a relationship between torque and rotation speed of a fresh air motor under different air resistances according to an embodiment of the present application, where, as shown in fig. 2C, an abscissa of the schematic diagram represents rotation speed and an ordinate represents torque; from the graph, when the rotating speeds of the fresh air motors are the same, the moment of the curve (3) is the largest, and the moment of the curve (1) is the smallest, so that the air resistance of the curve (3) is smaller than the air resistance of the curve (2), and the air resistance of the curve (2) is smaller than the air resistance of the curve (1); where n1 represents a first set rotational speed, n2 represents a second set threshold, and n3 represents a third set threshold.
Illustratively, the above method may further comprise: and the working parameter of the fresh air motor is smaller than a third set threshold value, the new wind motor in the fresh air conditioner is determined to be in fault, and the fault information of the fresh air motor is sent.
For example, when it is determined that the fresh air motor fails, to ensure the safety of the fresh air conditioner, the operation of the fresh air motor may be stopped, and the failure information of the fresh air motor may be sent; here, the fresh air motor failure information may be transmitted by lighting an indicator lamp, or by voice or text display.
The above process is specifically described below with reference to fig. 2D; fig. 2D is a flowchart of determining a detection result of a filter screen in a fresh air conditioner according to an embodiment of the present application, where, as shown in fig. 2D, the flowchart may include:
step A1: the fresh air conditioner starts a fresh air function.
Step A2: setting a fresh air motor rotating speed n=n0 (set rotating speed), running a time timer tk=0, a filter screen filth blocking state e1=0, a filter screen fault state e2=0, and a fresh air motor fault state e3=0.
