Fig. 2A is a flowchart of an air conditioner detection method provided in an embodiment of the present application, where the air conditioner detection method may be applied to a fresh air conditioner, and as shown in fig. 2A, the process may include:
step 200: determining that the fresh air motor is in an operating state, and detecting working parameters of the fresh air motor; the operating parameter includes rotational speed or current.
In the embodiment of the application, the fresh air conditioner comprises a fresh air motor with constant output power, and the fresh air motor is used for guiding outdoor fresh air to the indoor space; here, the magnitude of the constant output power may be set according to an actual usage scenario, for example, the constant output power may be set as a maximum output power of the fresh air motor, or may be set as a certain fixed power value smaller than the maximum output power, which is not limited in this embodiment of the application.
Illustratively, when the fresh air conditioner receives a control instruction for starting the fresh air function sent by a user, the fresh air conditioner starts the fresh air function; here, the manner in which the user transmits the control instruction is not limited; for example, the user may send the control instruction by means of a remote control or a control panel.
Exemplarily, after the fresh air conditioner starts the fresh air function, the fresh air motor starts to start; after the running time of the fresh air motor reaches the timing time, the working parameters of the fresh air motor, namely the actual rotating speed or the actual current of the fresh air motor, can be detected through the detection control unit; the working parameters of the fresh air motor are detected after the running time of the fresh air motor reaches the timing time, because the fresh air motor is in a running state when being started, but the working parameters are not stable, if the working parameters of the fresh air motor are detected at the moment, the stability of the working parameters can be reduced, and after the running time of the fresh air motor reaches the timing time, the working parameters of the fresh air motor are detected, so that the stability of the working parameters can be improved, and further, the accuracy of subsequent filter screen detection is ensured.
Here, the timing time may be preset by an operation time timer, and a value of the timing time may be determined according to an actual situation, which is not limited in the embodiment of the present application; for example, it may be 3 seconds, 5 seconds, or the like.
Exemplarily, fig. 2B is a schematic structural diagram of a fresh air motor in an operating state according to an embodiment of the present application, and referring to fig. 2B, a fresh air conditioner includes a centrifugal fan and a filter screen, besides 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 after being 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 size relation between the working parameters of the fresh air motor and 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 to determine the size relationship of the working parameters and the corresponding set threshold value, and then the detection result of the filter screen in the fresh air conditioner is determined according to the size relationship.
For example, 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 an installation-missing state; here, the missing or missing state may be collectively referred to as a filter failure state. Exemplarily, when the detection result of the filter screen is determined to be a dirty and blocked state, filter screen cleaning information is sent; and sending filter screen fault information when the detection result of the filter screen is determined to be in a neglected loading state or an unsettled installation state.
The filter screen cleaning information is sent to remind a user that the filter screen is dirty and blocked and needs to be cleaned or replaced; the function of sending filter screen trouble information is warning user's filter screen trouble, need to inspect whether the filter screen is installed or whether the filter screen is installed correctly. Exemplarily, the manner of transmitting the above two kinds of information is not limited; for example, the transmission may be performed by lighting an indicator lamp, voice, or text display.
In the embodiment of the application, when confirming that the filter screen is dirty stifled or the filter screen trouble, through sending warning information, the user of being convenient for is in time to do further operation to the filter screen, improves fresh air conditioner's result of use.
Exemplarily, according to the magnitude relation between the working parameter of the fresh air motor and at least one set threshold, the detection result of the filter screen in the fresh air conditioner is determined, which may include: when the working parameter of the fresh air motor is determined to be larger than or equal to a first set threshold value, the detection result of the filter screen is in a dirty and blocked state; when the working parameter of the fresh air motor is determined to be smaller than a first set threshold value and larger than or equal to a second set threshold value, the detection result of the filter screen is in a normal state; when the working parameter of the fresh air motor is determined to be smaller than the second set threshold value and larger than or equal to the third set threshold value, the detection result of the filter screen is in a neglected loading state or an out-of-position installation state.
For example, 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 operating parameter rotation speed and the current of the fresh air motor are positively correlated, and the manner of determining the filter screen detection result is the same for both, the rotation speed of the fresh air motor is taken as an example for description.
In the embodiment of the application, after the fresh air motor is started, the fresh air motor can be set to operate at a certain rotating speed, and the rotating speed is the set rotating speed; when the fresh air motor is in an operating state and the operating time reaches the timing time, the detected rotating speed is the actual rotating speed; here, because the output power of the fresh air motor is constant, the rotating speed and the torque of the fresh air motor are in inverse proportion; in addition, because the value range of the torque of the fresh air motor is fixed, when the set rotating speed is set to be larger, the actual rotating speed of the fresh air motor is possibly smaller than the set rotating speed; conversely, when the set rotation speed is set to be smaller, the actual rotation speed of the fresh air motor may be greater than the set rotation speed.
Illustratively, after the fresh air motor is started, the fresh air fan motor is set to operate 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 dirty and blocked, the filter screen needs to be cleaned or replaced by a new filter screen, 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 second set threshold, 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 fresh air motor is indicated to have a fault, and at the moment, the fresh air motor stops running; 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.
Exemplarily, assuming that after the fresh air motor is started, the rotation speed of the fresh air motor is set to be 5000 rpm (set rotation speed), and 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 installation-out-of-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 rotating speed of the fresh air motor may fluctuate between 2000 rpm (the second set threshold value) and 3000 rpm (the first set threshold value). If the detection result of the filter screen is in a filthy blockage state, the actual rotating speed of the fresh air motor may be greater than or equal to 3000 revolutions. If the motor fails, the speed may be below 50 rpm (the third set threshold).
For example, the principle of determining the detection result of the filter screen according to the rotating speed of the fresh air motor is explained; because the output power of the fresh air motor is constant, the rotating speed omega of the fresh air motor is inversely proportional to the torque T under the condition that the output power P of the power fresh air motor is constant according to the formula P which is T omega. Under the condition that a filter screen is not installed or the fresh air motor is not installed well, the air resistance is reduced, the air inlet is increased, the moment T is increased, and the rotating speed omega of the fresh air motor is reduced due to the constant output power P; on the contrary, under the condition that the filter screen of the fresh air motor is dirty and blocked, the air inlet becomes less, the air resistance becomes greater, the air inlet becomes less, at the moment, the torque T becomes less, and the rotating speed omega of the fresh air motor becomes greater due to the constant output power P. 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 a torque and a rotation speed of the fresh air motor under different air resistances according to the embodiment of the present application, as shown in fig. 2C, an abscissa of the schematic diagram represents the rotation speed, and an ordinate represents the torque; it can be known from the figure that when the rotating speeds of the fresh air motors are the same, the torque of the curve III is the largest, and the torque of the curve I is the smallest, so that the air resistance of the curve III is smaller than that of the curve II, and the air resistance of the curve II is smaller than that of the curve I; where n1 denotes the first set rotation speed, n2 denotes the second set threshold, and n3 denotes the third set threshold.
Exemplarily, the method may further include: and the working parameters of the fresh air motor are smaller than a third set threshold value, the failure of the fresh air motor in the fresh air conditioner is determined, and the failure information of the fresh air motor is sent.
Illustratively, when the fresh air motor is determined to have a fault, in order to ensure the safety of the fresh air conditioner, the operation of the fresh air motor can be stopped, and fault information of the fresh air motor is sent; here, the new air motor fault information may be transmitted by lighting an indicator lamp, voice, or text display.
The above process is specifically described 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, and as shown in fig. 2D, the flowchart may include:
step A1: the fresh air conditioner starts a fresh air function.
