Referring to fig. 2, an embodiment of the present invention provides an air conditioner control method including:
step S10, obtaining the temperature T of the inner plate of the air conditioner after the air conditioner starts heating;
in the present embodiment, when a user enters a room or a space provided with an air conditioner, the air conditioner needs to be turned on because of cold weather or hot weather, and the ambient temperature is adjusted by the air conditioner, for example, the air conditioner is turned on to cool or heat, and the present embodiment is described in terms of heating operation. The air conditioner is turned on according to an operation instruction of a user or according to an automatically set turn-on time, and enters a heating mode to adjust the temperature of the indoor environment to a set temperature (28 degrees or 30 degrees, etc.).
After the air conditioner enters a heating mode, the air conditioner operates according to operation parameters in the heating mode, for example, a compressor is started, an indoor fan and an outdoor fan are started, an air deflector is adjusted to a heating air guide angle and the like, the compressor does work on a refrigerant to exchange heat with the indoor air, and the indoor temperature is improved. In the heating process, the temperature T of an inner disc of the air conditioner is detected, the temperature T of the inner disc is the temperature of a coil pipe of an air conditioner internal heat exchanger, and the temperature T of the inner disc can be detected through a temperature detector arranged on the air conditioner internal heat exchanger to detect the temperature of the coil pipe of the indoor heat exchanger.
Step S20, judging whether the air conditioner frosts according to the change of the inner disc temperature T;
in step S10, after the detection of the inner tray temperature T is started, the detection is continued, and the change of the inner tray temperature T, for example, whether it is rising or falling or continuing to fall, is obtained by comparing the inner tray temperature detected last time with the inner tray temperature detected at present. And judging whether the air conditioner frosts or not according to the change of the temperature T of the inner disc. And in the process of detecting the inner disc temperature T, when the inner disc temperature T of the air conditioner is lower than T1(23 degrees or 24 degrees), the fan in the air conditioner does not operate until the air conditioner runs at low wind when the inner disc temperature reaches T2(27 degrees or 28 degrees), and the air conditioner runs at the set wind speed after the inner disc temperature (34 degrees or 35 degrees).
Judging frosting, if the temperature T of the inner disc is always increased and changed, the heating power is proved to be in, the air conditioner is normally heated, and the frosting is judged not to be formed; if the temperature T of the inner disc is decreased and continuously decreased, or decreased to 23 degrees or below 22 degrees, it is proved that the heating effect is poor, the air conditioner is in heating problem, the air conditioner is frosted, the outer unit cannot absorb heat, the evaporation pressure is too low, the indoor pressure is low, the air outlet temperature of the air conditioner is also low, and the heating effect is extremely poor. Or, the inner disc temperature T continues for 24 degrees or 25 degrees, the set temperature is 30 degrees, the set temperature is not reached, and the compressor power is maximum at this time, which indicates that the outdoor unit frosts and cannot provide continuous heating.
In one embodiment, referring to fig. 3, the determining whether the air conditioner is frosted according to the change of the inner panel temperature T includes:
step S21, calculating an inner plate temperature difference delta T according to the obtained inner plate temperature T of the air conditioner;
step S22, detecting the change situation of the inner disc temperature T when the inner disc temperature difference delta T reaches the first temperature difference Tg 1;
and step S23, when the inner disc temperature T is less than the fixed temperature value, judging that the air conditioner frosts.
Judging whether frosting is caused or not according to the change of the inner disc temperature T, firstly acquiring the temperature difference of the inner disc temperature, comparing the last acquired inner disc temperature with the current inner disc temperature to obtain an inner disc temperature difference delta T, comparing the inner disc temperature difference delta T with a first temperature difference Tg1, setting the first temperature difference Tg1 to be 6 degrees, or 5 degrees or 7 degrees and the like, and setting according to the actual operation condition of the air conditioner or default setting in advance. When the inner disc temperature difference delta T reaches the first temperature difference Tg1, the change condition of the inner disc temperature T is detected, whether the inner disc temperature T reaches a fixed temperature value or not is judged, and the fixed temperature value is 38 degrees or 39 degrees and the like and is set according to requirements. And when the temperature T of the inner disc is less than the fixed temperature value, judging that the air conditioner frosts. Optionally, the inner disc temperature difference Δ T is the highest inner disc temperature detected before, and whether the first temperature difference Tg1 is reached is determined by the temperature difference between the highest inner disc temperature and the current inner disc temperature T; of course, the temperature of the inner disc can be directly compared with the last detected temperature of the inner disc. Judging whether the inner disc temperature T reaches a fixed temperature value or not, and determining the currently acquired inner disc temperature T of the air conditioner and the detected maximum inner disc temperature Tmax; and calculating the temperature difference between the inner disc temperature T and the maximum inner disc temperature Tmax, and marking as the inner disc temperature difference delta T. Specifically, the maximum inner disc temperature Tmax is obtained by detecting the inner disc temperature T, and when the inner disc temperature Tmax is smaller than a fixed temperature value, it is determined that the air conditioner is frosted.
In one embodiment, referring to fig. 4, when the inner panel temperature T is less than the fixed temperature value, the step of determining that the air conditioner is frosted includes:
step S201, when the inner disc temperature T is smaller than a fixed temperature value, judging whether the inner disc temperature T is smaller than a first preset value, wherein the first preset value is the inner disc temperature T + T0, and T0 is an integer temperature value;
and step S202, when the temperature T of the inner disc is less than a first preset value, judging that the air conditioner frosts.
When the inner disc temperature T is smaller than a fixed temperature value, judging whether the inner disc temperature T is smaller than a first preset value, wherein the first preset value is the inner disc temperature T + T0, and T0 is an integer temperature value; the inner disc temperature of the first preset value is the currently detected inner disc temperature T, T0 can be 1 or 2, and the like, and is set according to requirements; for example, if the current inner panel temperature T is 28 degrees, the next detected inner panel temperature T is 29 degrees, which is less than 28 degrees +2 degrees, it is determined that the air conditioner is frosted. For more accurate judgment, when the inner tray temperature T is less than the first preset value, it is judged whether the inner tray temperature T is continuously less than the first preset value, and after lasting m minutes, for example, 2 minutes or 3 minutes, it is judged that the air conditioner is frosted. When the frosting condition is not met, the air conditioner is judged not to be frosted, for example, the inner disc temperature T is greater than a fixed temperature value, or the inner disc temperature T is greater than a first preset value.
In an embodiment, when it is determined that the air conditioner is not frosted according to the above method, referring to fig. 5, after the step of determining whether the inner panel temperature T is less than the first preset value when the inner panel temperature T is less than the fixed temperature value, the method further includes:
step S301, when the inner disc temperature T is greater than a first preset value, judging whether the inner disc temperature difference delta T reaches a second temperature difference Tg2, wherein Tg2 is greater than Tg 1;
step S302, when the inner disc temperature difference delta T reaches a second temperature difference Tg2, detecting the change condition of the inner disc temperature T;
and step S303, judging that the air conditioner frosts when the inner disc temperature T is less than the fixed temperature value.
The second temperature difference Tg2 is greater than Tg1, and may be, for example, 8 degrees, 9 degrees, or the like; and after the temperature difference is greater than the first temperature difference Tg1, judging whether the temperature difference is greater than the second temperature difference Tg2, detecting the change condition of the inner disc temperature T when the inner disc temperature difference delta T reaches the second temperature difference Tg2, continuously detecting the inner disc temperature T, judging whether the fixed temperature value is met or not, judging the condition of frosting, and if so, judging the air conditioner frosting. The second temperature difference Tg2 is additionally arranged when the first temperature difference Tg1 is reached, so that frosting judgment is more reasonable and accurate, frosting misjudgment is avoided, and accuracy of frosting judgment is improved.
And step S30, after the frosting of the air conditioner is judged according to the change of the temperature T of the inner disc, the air conditioner enters a defrosting mode, and the operation of the air conditioner is controlled according to the operation parameters in the defrosting mode.
And after the frosting of the air conditioner is judged according to the change of the temperature of the inner disc, the defrosting mode is entered, and the operation of the air conditioner is controlled according to the operation parameters in the defrosting mode. And after the frosting of the air conditioner is not judged, the air conditioner is continuously operated according to the current heating parameters without action. And the defrosting operation may be performed by: after the compressor A (5s or 6s and the like) is closed for a second, the outer fan and the four-way valve are closed, the compressor is started after the delay B (3s or 4s and the like) for a second, the defrosting time is Tc (5 minutes or 6 minutes and the like), then the compressor is closed while the outer fan is started, the four-way valve is started after the delay B1(3s or 2s and the like) for a second, and the compressor is started after the delay A1(3s or 4s and the like) for a second. The above time is set according to the control of defrosting or by default in advance, and the above example is not limited to just one example.
In the embodiment, in the heating process of the air conditioner, the brand-new inner disc temperature is adopted, whether the air conditioner frosts or not is judged according to the change of the inner disc temperature, and the air conditioner is controlled to dehumidify in a defrosting mode after frosting; the mode that the inner disc temperature that this application was taken judges whether frosting is different with the outer wiring of present needs air conditioner, only need in the inside inner disc temperature sensor that increases of air conditioner detect the inner disc temperature can, need not to bring the problem of installation at the outside wiring of air conditioner, because of need not outside wiring and installation regulation for cost reduction, easy to assemble, strong operability.
In an embodiment of the present invention, referring to fig. 6, after the step of entering a defrosting mode after determining that the air conditioner is frosted according to the change of the inner panel temperature T, and controlling the operation of the air conditioner according to the operation parameters in the defrosting mode, the method further includes:
step S40, detecting the temperature Tx of the inner disk of the air conditioner again;

and step S60, judging that the air conditioner is not frosted when the change condition of the inner disk temperature Tx is an ascending change, and operating according to the current operation parameters.
After the air conditioner is defrosted, the condition of incomplete defrosting may occur, after defrosting, the temperature of the inner disc after defrosting is monitored in real time, and the temperature Tx of the inner disc of the air conditioner is detected again and is the temperature of the inner disc after defrosting; if the temperature Tx of the inner disc is in an ascending trend, the frosting condition is avoided; if the operation is performed for 5 minutes (the preset time, or other set time), the number of times that the inner disc temperature Tx is less than the third preset value is recorded within the 5 minutes, and the number of times that the inner disc temperature Tx is less than the third preset value is recorded within more than 5 minutes, or the number of times that the inner disc temperature Tx is recorded within 5 minutes reaches the third preset number, it is determined that the air conditioner is not defrosted completely, and the defrosting operation is maintained. The temperature of the inner disc is judged again in the defrosting process and after defrosting, the condition that defrosting is not completely removed is prevented, and the defrosting effect is improved.
To better describe the embodiment of the present invention, referring to fig. 7, the defrosting process of the air conditioner in fig. 7 includes: defining the inner disc temperature: IPT; inner disc maximum temperature: IPTmax, temperature difference of inner disc: Δ IPT;

If the air conditioner detects that the IPT of the air conditioner is lower than T1(23 degrees) for 3 times after the air conditioner operates for 5 minutes, the air conditioner judges that the outer unit condenser has missed frost and is not completely removed, and defrosting operation is carried out. And after the compressor is closed for A seconds, the outer fan and the four-way valve are closed, the compressor is started after B seconds are delayed, the defrosting time is Tc, then the compressor is closed, the outer fan is started simultaneously, the four-way valve is started after B1 seconds are delayed, and the compressor is started after A1 seconds are delayed. When the IPT is monitored by the controller in real time to be lower than T1(23 degrees), the fan in the air conditioner does not operate, and the fan in the air conditioner does not operate until the IPT reaches T2(27 degrees), the air conditioner operates at low wind speed, and the air conditioner operates at the set wind speed after T3(34 degrees). The controller monitors IPT in real time, next data are compared with previous data, and when the temperature range of the inner disc of the air conditioner rises, the air conditioner judges that frosting does not exist. If the IPT reaches the Tz, the air conditioner stops running the outer fan, and the controller monitors that the IPT reaches the Tt in real time and the outer fan is started. And if the IPT reaches the Tmax, stopping the operation of the compressor. The controller monitors IPT in real time, next data is compared with the previous data, when the temperature difference delta IPT between the current temperature Td and the highest point temperature detected in the front is detected to be equal to 6 degrees, IPTMax is judged, if the temperature difference delta IPT is smaller than 38 degrees, calculation is started at the moment, if IPT is continuously carried out for M minutes and is lower than Td +1, the air conditioner judges that the external unit is frosted, defrosting is carried out, and defrosting action is carried out.
