First embodiment of the method for detecting the swing direction of the air deflector
Referring to fig. 1, an embodiment of the present application provides a method for detecting a swing direction of an air deflector, where the method for detecting the swing direction of the air deflector includes the following steps:
and step S10, driving the air conditioner to be started and operating for a first time, wherein the first time is the time required by the air deflector to rotate to the preset position after the air conditioner is started.
The step S10 specifically includes: the air conditioner is driven to be started, the driving motor of the air deflector drives the air deflector to rotate, and after the air conditioner operates for the first time, the driving motor of the air deflector drives the air deflector to rotate to a preset position.
In this embodiment, the preset position is a position where the air deflector is parallel to the air outlet direction. In some possible embodiments, the preset position may also be a position where the air deflector is located approximately parallel to the air outlet direction. Specifically, the air outlet direction of the air conditioner is the horizontal direction, and when the air deflector rotates to the horizontal position or is close to the horizontal position, the air deflector rotates to the preset position.
The first time is the time required when the air deflector rotates to the preset position after the air conditioner is started, and the first time is automatically acquired through a timer. Specifically, a tester firstly starts the good air conditioner, the air conditioner automatically starts timing at the moment of starting, a driving motor of the air deflector firstly rotates reversely by a certain angle to ensure that the air deflector is in a closed state, then rotates forwards by a certain angle to drive the air deflector to rotate to a horizontal position or a position close to the horizontal position and keep the air deflector immovable, the timing is finished, corresponding time is recorded as first time, and then the tester inputs the first time into a memory before batch detection. Since the air deflector is kept stationary after rotating to the preset position, the current passing through the fan is kept unchanged after the air deflector rotates to the preset position, so that the actual operation time of the air conditioner can be greater than or equal to the first time in the actual detection.
And step S20, detecting the current passing through the fan after the air conditioner operates for the first time and recording the current as the first current.
In this embodiment, the timer is used for automatically counting time, and after the air conditioner runs for the first time, the current detection module is used for automatically detecting the current passing through the fan at the moment, and generating a current signal to record the current signal as the first current.
And step S30, comparing the first current with a first preset current, wherein the first preset current is the current passing through the fan after the air conditioner runs for the first time under the condition that the swing direction of the air deflector is wrong.
In this embodiment, the current detection module obtains the first current and then transmits the current signal to the processor, and the processor receives the current signal and then compares the first current with a first preset current. The first preset current is obtained by detection personnel before detection, specifically, the detection personnel start the air conditioner of a defective product and operate for the first time, then the current passing through the fan is obtained, and then before batch detection, the detection personnel input the current value into the memory and record the current value as the first preset current.
In step S40, if the first current is equal to the first predetermined current, it is determined that the swing direction of the air deflector is incorrect.
In this embodiment, when performing batch detection, after receiving a current signal of the first current, the processor compares the first current with a first preset current, and if the comparison result is that the first current is equal to the first preset current, it is determined that the air deflector does not rotate to a preset position after the air conditioner operates for a first time, that is, a swing direction error of the air deflector is obtained, and then it is determined that a sequence error of welding wires by a driving motor of the air deflector is determined.
In step S41, if the first current is not equal to the first preset current, it is determined that the swing direction of the air deflector is correct.
In this embodiment, during the batch detection, after receiving the current signal of the first current, the processor compares the first current with a first preset current, and if the comparison result shows that the first current is not equal to the first preset current, it is determined that the swing direction of the air deflector is correct.
The embodiment of the application provides a method for detecting the swing direction of an air deflector, which is used for judging whether the sequence of welding wires by a driving motor of the air deflector is correct or not. Specifically, in this embodiment, after the air conditioner to be detected is turned on and operated for the first time, the current passing through the fan at this time is detected and recorded as the first current, and then whether the first current is equal to the first preset current is automatically determined by a program, if the determination result is that the first current is equal to the first preset current, it is determined that the air deflector does not rotate to the preset position after the air conditioner is operated for the first time, that is, the swing direction error of the air deflector is obtained, and further, it is determined that the sequence error of the wire welding of the driving motor of the air deflector is determined. The method for detecting the swing direction of the air deflector can directly and effectively detect the defective products caused by the wrong sequence of welding wires by the driving motor of the air deflector in production, and improves the detection efficiency.
It should be noted that, in this embodiment, the detection is performed on the premise that the air conditioner devices, such as the fan, the air deflector, and the driving motor of the air deflector, are not damaged or damaged, so in step S30, the comparison result of comparing the first current with the first preset current only has two results, that is, the first current is equal to the first preset current, it is determined that the swing direction of the air deflector is wrong, or the first current is not equal to the first preset current, it is determined that the swing direction of the air deflector is correct.
Second embodiment of the method for detecting the swing direction of the air deflector
Compared with the first embodiment of the present application, in the present embodiment, after the swing direction error of the air deflector is detected, a step of automatically adjusting the excitation sequence of the driving motor of the air deflector so as to make the swing direction of the air deflector correct is added.
Specifically, referring to fig. 2, after step S40, the method further includes:
in step S50, the excitation sequence of the drive motor of the air deflector is automatically adjusted so that the swing direction of the air deflector is correct.
In this embodiment, after the processor determines that the swing direction of the air deflector is incorrect, the processor outputs a control signal to control the excitation sequence of the driving motor of the air deflector, so that the driving motor of the air deflector drives the air deflector in the direction opposite to the original direction, and the swing direction of the air deflector is correct.
Specifically, the driving motor of the air deflector is a stepping motor, for example, a commonly used four-phase eight-beat stepping motor, and as shown in the figure, when the driving motor of the air deflector is correctly welded with the electric wire, the excitation sequence of the driving motor of the air deflector is "red orange → red orange yellow → red yellow powder → red powder blue → red blue orange". When the processor confirms that the swinging direction of the air deflector is wrong, the processor outputs a control signal to control the excitation sequence of the driving motor of the air deflector, and the excitation sequence of the driving motor of the air deflector is adjusted to be 'red powder → red powder yellow → red yellow orange → red orange blue → red blue powder', so that the driving motor of the air deflector drives the air deflector in the direction opposite to the original direction, and the swinging direction of the air deflector is correct.
In some possible embodiments, when the processor determines that the swing direction of the air deflector is wrong, the processor outputs a control signal to control the excitation sequence of the driving motor of the air deflector, and the excitation sequence of the driving motor of the air deflector can be adjusted to "red orange → red orange blue → red blue powder → red powder yellow → red yellow orange", so that the driving motor of the air deflector can drive the air deflector in the direction opposite to the original direction, and the swing direction of the air deflector is correct.
Third embodiment of the present application, a method for detecting a swing direction of an air deflector
Compared with the embodiment of the present application, in the embodiment, after the first current is determined not to be equal to the first preset current, and before the swing direction of the air deflector is determined to be correct, a step of comparing the first current with the second preset current is added to further determine whether the swing direction of the air deflector is correct.
Specifically, referring to fig. 3, the method for detecting the swing direction of the air deflector provided in this embodiment includes the following steps:
and step S10, driving the air conditioner to be started and operating for a first time, wherein the first time is the time required by the air deflector to rotate to the preset position after the air conditioner is started.
And step S20, detecting the current passing through the fan after the air conditioner operates for the first time and recording the current as the first current.
And step S30, comparing the first current with a first preset current, wherein the first preset current is the current passing through the fan after the air conditioner runs for the first time under the condition that the swing direction of the air deflector is wrong.
In step S40, if the first current is equal to the first predetermined current, it is determined that the swing direction of the air deflector is incorrect.
In this embodiment, when performing batch detection, after receiving a current signal of the first current, the processor compares the first current with a first preset current, and if the comparison result is that the first current is equal to the first preset current, it is determined that the air deflector does not rotate to a preset position after the air conditioner operates for a first time, that is, a swing direction error of the air deflector is obtained, and then it is determined that a sequence error of welding wires by a driving motor of the air deflector is determined.
In step S50, if the oscillating direction of the air deflector is confirmed to be wrong, the excitation sequence of the drive motor of the air deflector is automatically adjusted so that the oscillating direction of the air deflector is correct.
In this embodiment, when the first current is equal to the first predetermined current, that is, the swing direction of the air deflector is incorrect, the processor outputs the control signal to control the excitation sequence of the driving motor of the air deflector, so that the driving motor of the air deflector drives the air deflector in the direction opposite to the original direction, and the swing direction of the air deflector is correct.
And step S42, if the first current is not equal to the first preset current, comparing the first current with a second preset current, wherein the second preset current is the current passing through the fan after the air conditioner runs for the first time under the condition that the swing direction of the air deflector is correct.
The second preset current is obtained by detection personnel before detection, specifically, the detection personnel start the air conditioner of a good product and operate for the first time, then the current passing through the fan is obtained, and then before batch detection, the detection personnel input the current value into the memory and record the current value as the second preset current.
In step S51, if the first current is equal to the second predetermined current, it is determined that the swing direction of the air deflector is correct.
In this embodiment, during batch detection, after the processor receives a current signal of the first current, the first current is compared with the second preset current, and if the comparison result shows that the first current is equal to the second preset current, it is determined that the air deflector normally rotates to the preset position after the air conditioner operates for the first time, that is, the air deflector swings in the correct direction, and then it is determined that the sequence of welding the wires by the driving motor of the air deflector is correct.
In step S52, if the first current is not equal to the second preset current, it is determined that the air conditioner is faulty.
The working flow of this embodiment is: after the air conditioner is driven to be started and operated for the first time, the current passing through the fan at the moment is detected and recorded as a first current, then the first current is compared with a first preset current, if the first current is equal to the first preset current, the swinging direction error of the air deflector is confirmed, and then the excitation sequence of the driving motor of the air deflector is automatically adjusted so that the swinging direction of the air deflector is correct. If the first current is not equal to the first preset current, comparing the first current with a second preset current, and if the first current is equal to the second preset current, determining that the swing direction of the air deflector is correct; and if the first current is not equal to the second preset current, confirming the air conditioner fault.
Fourth embodiment of the present disclosure is a method for detecting a swing direction of an air guide plate
Compared with the present embodiment, in the present embodiment, after the first current is determined not to be equal to the first preset current, and before the swing direction of the air deflector is determined to be correct, a step of comparing the first current with a third preset current is added to determine whether the driving motor of the air deflector is damaged.
Specifically, referring to fig. 4, the method for detecting the swing direction of the air deflector provided in this embodiment includes the following steps:
and step S10, driving the air conditioner to be started and operating for a first time, wherein the first time is the time required by the air deflector to rotate to the preset position after the air conditioner is started.
And step S20, detecting the current passing through the fan after the air conditioner operates for the first time and recording the current as the first current.
Step S30, comparing the first current with a first preset current, wherein the first preset current is the current passing through the fan after the air conditioner runs for the first time under the condition that the swing direction of the air deflector is wrong;
in step S40, if the first current is equal to the first predetermined current, it is determined that the swing direction of the air deflector is incorrect.
In step S50, if it is determined that the oscillating direction of the air guide plate is incorrect, the excitation sequence of the drive motor of the air guide plate is automatically adjusted so that the oscillating direction of the air guide plate is correct.
And step S43, if the first current is not equal to the first preset current, comparing the first current with a third preset current, wherein the third preset current is the current passing through the fan after the air conditioner runs for the first time under the condition that the driving motor of the air deflector is damaged.
The third preset current is obtained by a detector before detection, specifically, the detector starts the damaged air conditioner of the driving motor of the air deflector and operates for the first time to obtain the current passing through the fan at the moment, and then before batch detection, the detector inputs the current value into the memory and records the current value as the third preset current. In this embodiment, a scene in which the driving motor of the air deflector is damaged can be simulated by not accessing the driving motor of the air deflector.
In step S53, if the first current is equal to the third predetermined current, it is determined that the driving motor of the air deflector is damaged.
In this embodiment, during the batch detection, after the processor receives the current signal of the first current, the first current is compared with the third preset current, and if the comparison result shows that the first current is equal to the third preset current, it is determined that the driving motor of the air deflector is damaged.
In step S54, if the first current is not equal to the third predetermined current, it is determined that the swing direction of the air deflector is correct.
In this embodiment, when the first current is not equal to the first preset current and the third preset current, the swing direction of the air deflector can be further determined to be correct, so as to avoid a situation that the swing direction of the air deflector is misjudged to be correct due to damage of a driving motor of the air deflector.
The working flow of this embodiment is: after the air conditioner is driven to be started and operated for the first time, the current passing through the fan at the moment is detected and recorded as a first current, then the first current is compared with a first preset current, if the first current is equal to the first preset current, the swinging direction error of the air deflector is confirmed, and then the excitation sequence of the driving motor of the air deflector is automatically adjusted so that the swinging direction of the air deflector is correct. If the first current is not equal to the first preset current, comparing the first current with a third preset current, and if the first current is equal to the third preset current, determining that the drive motor of the air deflector is damaged; if the first current is not equal to the third preset current, the swing direction of the air deflector is confirmed to be correct.
