The embodiment of the invention also provides a control method of the air conditioner, which is applied to the air conditioner.
Referring to fig. 2, a first embodiment of a control method of an air conditioner of the present invention is presented. In this embodiment, the control method of the air conditioner includes:
step S10, detecting the water level of a water receiving disc of an indoor unit of the air conditioner in the running process of the air conditioner;
the embodiment of the invention can be implemented in an air conditioner or a control terminal of the air conditioner, and the embodiment is described by taking the air conditioner as an example.
In this embodiment, during the operation of the air conditioner, when the cooling mode is started, the temperature of the indoor heat exchanger of the air conditioner is low, water vapor in the environment where the indoor unit of the air conditioner is located encounters the cold indoor heat exchanger and then liquefies into small water droplets, condensed water is formed on the surface of the indoor heat exchanger, and the condensed water is collected through a water receiving disc installed below the indoor heat exchanger so as to drain the condensed water outdoors through a drain pipe connected with the water receiving disc.
It can be understood that in the operation process of the air conditioner, when the refrigerating mode is started, condensed water is accumulated in the water receiving disc of the indoor unit of the air conditioner, and excessive accumulated water in the water receiving disc easily causes the risk of accumulated water in the indoor unit to be increased, so that the water receiving disc water level of the indoor unit is detected in real time, and the risk of excessive accumulated water in the water receiving disc is avoided.
Step S20, when the water level of the water receiving disc is greater than or equal to a first preset water level, adjusting the operation parameters of the air conditioner so as to reduce the water discharged into the water receiving disc; wherein the operating parameter includes at least one of a compressor operating frequency and a rotational speed of the indoor fan.
Based on this, in the operation process of the air conditioner, the embodiment detects the water level of the water receiving disc of the indoor unit of the air conditioner in real time or at fixed time, and monitors whether the water level of the water receiving disc is too high in real time or at fixed time.
Optionally, the detection method of the water level of the water receiving disc of the indoor unit of the air conditioner in this embodiment includes at least one of:
in one embodiment, a water level sensor is arranged on the water receiving disc, and the water level of the water receiving disc is detected through the water level sensor. Optionally, the water level sensor is connected with a controller of the air conditioner, when the water level sensor detects that the water level of the water receiving disc reaches a first preset water level, a signal is sent to the controller, and the controller determines that the water level of the water receiving disc is greater than or equal to the first preset water level according to the signal.
In another embodiment, a water level switch is arranged in the water receiving disc, the water level switch comprises a movable contact and a fixed contact, the movable contact can sink and float along with water, when the movable contact is in contact with the fixed contact, the water level switch is conducted, the controller receives a conducting signal of the water level switch, when the movable contact is separated from the fixed contact, the water level switch is disconnected, and the controller receives a disconnection signal of the water level switch.
In this embodiment, the air conditioner determines whether the water level of the water pan reaches a first preset water level according to the on-off signal of the water level switch. In an embodiment, when the fixed contact is at a position where the first preset water level is, and the air conditioner receives a conducting signal of the water level switch, it is determined that the water level of the water receiving disc reaches the first preset water level. In another embodiment, when the fixed contact is located below the first preset water level, the air conditioner determines that the water level of the receiving tray reaches the first preset water level when receiving an off signal of a water level switch.
Optionally, the first preset water level is a critical value of a water level of the water receiving disc, where the preset water receiving disc has excessive water accumulation risk.
In this way, whether the water level of the water receiving disc is larger than or equal to a preset first water level is detected, if the water level of the water receiving disc is larger than or equal to the first preset water level, the risk of excessive accumulated water in the water receiving disc is judged, and the operation parameters of the air conditioner are adjusted so as to reduce the water discharged into the water receiving disc; if the water level of the water receiving disc is smaller than the first preset water level, the water receiving disc is judged to have no risk of excessive water accumulation, the air conditioner is controlled to operate according to the current operation parameters, when the water receiving disc of the indoor unit has the risk of excessive water accumulation, the operation parameters of the air conditioner are adjusted to improve the temperature of the indoor heat exchanger, reduce condensed water generated by water vapor liquefaction, further avoid the excessive condensed water accumulated in the water receiving disc, the risk of water soaking of the air conditioner and the risk of water soaking of the air conditioner on the ceiling of a room where the air conditioner is located are further avoided, and further the damage of the air conditioner and the ceiling caused by water soaking and water soaking of the indoor unit is avoided.
Optionally, in an embodiment, when a water pump is provided in an indoor unit of the air conditioner, the water pump is turned on; wherein, the adjustment amount of the operation parameter of the air conditioner with the water pump in the indoor unit is smaller than the adjustment amount of the operation parameter of the air conditioner without the water pump in the indoor unit.
It can be understood that when the indoor unit of the air conditioner is equipped with the water pump, when the water level of the water receiving disc is greater than or equal to the first preset water level, the water in the water receiving disc is pumped by the water pump, and meanwhile, the operation parameters of the air conditioner are adjusted, the condensed water discharged into the water receiving disc is reduced, so that the accumulated water in the water receiving disc is discharged.
Thus, when the water pump is arranged in the indoor unit of the air conditioner, the water pump is started, the water level of the water receiving disc of the indoor unit of the air conditioner is detected, when the water level of the water receiving disc is still larger than or equal to a first preset water level, the operation parameters of the air conditioner are adjusted so as to further reduce condensed water discharged into the water receiving disc, the water accumulation of the water receiving disc in the indoor unit is pumped by the water pump, and the operation parameters of the air conditioner are adjusted so as to avoid the increase of the water accumulation of the water receiving disc.
Optionally, by adjusting the operating frequency of the compressor and/or the rotational speed of the indoor fan to increase the temperature of the indoor heat exchanger, the condensed water on the surface of the indoor heat exchanger is further reduced, so that the water discharged into the water receiving disc is reduced.
Optionally, in an embodiment, the temperature of the indoor heat exchanger is increased by reducing the frequency of operation of the compressor, reducing the dosage of refrigerant processed by the compressor per unit time, and/or by increasing the rotational speed of the indoor fan, increasing the heat exchange between the indoor heat exchanger and the indoor environment in which the indoor unit is located, and thereby increasing the temperature of the indoor heat exchanger.
Optionally, in a further embodiment, the operating frequency of the compressor is reduced at intervals of a preset time until it is detected that the water pan level of the indoor unit is less than a second preset level, and the second preset level is less than or equal to the first preset level.
In this embodiment, the preset time interval is a preset time interval for reducing the operation frequency of the compressor, and may be 10 seconds, or may be 20 seconds, or may be 30 seconds; the second preset water level is a critical value of the water level of the water receiving disc for eliminating the risk of excessive accumulated water in the preset water receiving disc.
Optionally, in an embodiment, a reduction value for reducing the operating frequency of the compressor is determined according to a difference between a water level of the water receiving disc of the indoor unit and a second preset water level and a difference between a set temperature of the air conditioner and an indoor environment temperature of an environment in which the indoor unit is located, the operating frequency of the compressor is reduced according to the reduction value, the operating frequency of the compressor is reduced based on the difference between the water level of the water receiving disc and the second preset water level and the difference between the set temperature and the indoor environment temperature, for example, when the reduction value is 10, the operating frequency of the compressor is reduced by 10, and the reduction value of the operating frequency of the compressor is adjusted according to the difference between the indoor environment temperature and the set temperature, so that the influence of the reducing the operating frequency of the compressor on the indoor comfort is reduced, thereby reducing the condensed water discharged to the water receiving disc, and simultaneously avoiding that excessive reduction of the operating frequency of the compressor causes the indoor comfort difference.
Optionally, in another embodiment, a reduction value for reducing the operating frequency of the compressor is determined according to a difference between the water level of the water receiving disc of the indoor unit and the second preset water level and a difference between the set temperature of the air conditioner and the indoor environment temperature of the environment in which the indoor unit is located, the operating frequency of the compressor is reduced once every preset time interval according to the reduction value until the water level of the water receiving disc of the indoor unit is detected to be smaller than the second preset water level, for example, when the preset time interval is 10 seconds and the reduction value is 10, the operating frequency of the compressor is reduced by 10 seconds every 10 seconds, and the reduction value of the operating frequency of the compressor is determined based on the difference between the indoor environment temperature and the set temperature and the water level of the water receiving disc and the second preset water level, so that the operating frequency of the compressor is reduced a small number of times, and the indoor comfort level is avoided when the compressor frequency is directly reduced once.
Optionally, in another embodiment, a reduction value for reducing the operating frequency of the compressor is determined according to a first water level difference between the water pan water level of the indoor unit and a second preset water level and a first difference between the set temperature of the air conditioner and the indoor environment temperature of the environment in which the indoor unit is located, after a first preset time interval, the operating frequency of the primary compressor is reduced according to the reduction value, an adjustment value for the reduction value is determined according to a second difference between the set temperature of the air conditioner and the indoor environment temperature of the environment in which the indoor unit is located and a second water level difference between the water pan water level of the indoor unit and the second preset water level, the reduction value is adjusted according to the adjustment value, after a second preset time interval, the operating frequency of the primary compressor is reduced according to the adjusted reduction value, and returning to execute the step of determining an adjustment value of the reduction value according to a second difference value between the set temperature of the air conditioner and the indoor environment temperature of the environment where the indoor unit is located and a second water level difference between the water receiving disc water level of the indoor unit and a second preset water level until the water receiving disc water level of the indoor unit is detected to be smaller than the second preset water level, for example, when the reduction value is 10, a preset time interval is 10 seconds, the adjustment value is +1, the operation frequency of the compressor is reduced by 10 th and 20 th seconds, the operation frequency of the compressor is reduced by 11 th, and each time the operation frequency of the compressor is reduced, the adjustment value corresponding to the reduction value of the operation frequency of the compressor is adapted to perform multiple adjustments on the reduction value, so that the influence of the operation frequency of the reduction of the compressor on indoor comfort is further reduced.
The detection mode of the water level of the water pan of the indoor unit of the air conditioner of the embodiment comprises at least one of the following steps:
in one embodiment, a water level sensor is arranged on the water receiving disc, and the water level of the water receiving disc is detected through the water level sensor. Optionally, the water level sensor is connected with a controller of the air conditioner, when the water level sensor detects that the water level of the water receiving disc is smaller than a second preset water level, a signal is sent to the controller, and the controller determines that the water level of the water receiving disc is smaller than the second preset water level according to the signal.
In another embodiment, a water level switch is arranged in the water receiving disc, the water level switch comprises a movable contact and a fixed contact, the movable contact can sink and float along with water, when the movable contact is in contact with the fixed contact, the water level switch is conducted, the controller receives a conducting signal of the water level switch, when the movable contact is separated from the fixed contact, the water level switch is disconnected, and the controller receives a disconnection signal of the water level switch.

if not, the step S20 is executed when the water level of the water pan of the indoor unit of the air conditioner is detected to be greater than or equal to the second preset water level.
Optionally, in an embodiment, when it is detected that the water level of the water pan of the indoor unit of the air conditioner is less than the second preset water level, the air conditioner is controlled to operate according to the adjusted operation parameter.
Optionally, in another embodiment, when the water pan water level of the indoor unit of the air conditioner is detected to be smaller than the second preset water level, the air conditioner is controlled to operate with the initial operation parameters before the operation parameters are adjusted.
Optionally, in another embodiment, when the water pan water level of the indoor unit of the air conditioner is detected to be smaller than the second preset water level, the target indoor heat exchanger temperature of the air conditioner is obtained, and the air conditioner is controlled to operate at the target indoor heat exchanger temperature.
It will be appreciated that in the cooling mode, the target indoor heat exchanger temperature is the target evaporation temperature and in the heating mode, the target indoor heat exchanger temperature is the target condensation temperature, and in some embodiments, the target indoor heat exchanger temperature may be the same as the set temperature or different from the set temperature.
Therefore, after the operation parameters of the air conditioner are adjusted, the temperature of the indoor heat exchanger of the air conditioner is easy to be too high, and then the indoor environment temperature where the indoor unit is located is too high, so that the indoor comfort level is poor, when the water receiving disc water level is detected to be smaller than a second preset water level, namely, when the water receiving disc relieves the risk of excessive accumulated water, the air conditioner is timely restored to the operation parameters before adjustment, the technical defect that the indoor comfort level is poor due to the fact that the temperature of the indoor heat exchanger is too high when the operation parameters of the air conditioner are not timely restored is avoided, and therefore the indoor comfort level can still be met after the water soaking risk of the indoor unit is solved, and the functional effect of the air conditioner is optimized.
Referring to fig. 4, a third embodiment of a control method of an air conditioner is proposed based on the first embodiment or the second embodiment, and in this embodiment, after step S40, the method further includes:
when the water level of the water pan of the indoor unit of the air conditioner is detected to be smaller than the second preset water level, executing a step S50, and acquiring the total adjustment duration of the operation parameters of the air conditioner;
step S60, judging whether the total adjustment duration is greater than or equal to a preset duration;

if not, that is, when the total adjustment duration is less than the preset duration, the step S40 is executed again.
In this embodiment, the preset time period is a preset critical value for determining the adjustment time period of the adjustment operation parameter when the operation condition of the air conditioner for handling the excessive water accumulation problem of the water pan is normal.
Optionally, in an embodiment, a first time point when the water level of the water pan is detected to be greater than or equal to a first preset water level is obtained, and an adjustment total duration of the operation parameter of the air conditioner is obtained according to a time difference between the first time point and the second time point when the water level of the water pan is detected to be greater than or equal to the first preset water level.
Optionally, in another embodiment, when the water level of the water pan is detected to be greater than or equal to a first preset water level, the adjustment times of the operation parameters of the air conditioner are started to be adjusted, and the total adjustment duration of the operation parameters of the air conditioner is determined according to the product between the adjustment times and a preset time interval for adjusting the operation parameters.
It can be understood that in an embodiment, when the indoor unit of the air conditioner is equipped with the water pump, the water in the water receiving tray is pumped by the water pump, and meanwhile, by adjusting the operation parameter of the air conditioner, the condensed water discharged into the water receiving tray is reduced so as to remove the accumulated water in the water receiving tray.

Therefore, the total adjustment duration of the operation parameters of the air conditioner is adjusted to realize real-time monitoring on the capacity of the air conditioner for treating the water accumulation problem of the water collecting tray, when the total adjustment duration is longer than or equal to the preset duration, the capacity of the air conditioner for treating the water accumulation problem of the water collecting tray is lower, the air conditioner is controlled to stop operation and/or output fault prompts, so that a user overhauls the air conditioner when observing that the operation appears, the capacity of the air conditioner for treating the water accumulation problem of the water collecting tray is always in a normal range in the operation process, and the risk of water soaking of the air conditioner is further reduced.
Optionally, in some embodiments, after the returning to the step S40, when the total adjustment duration is less than the preset duration, the number of times of adjustment of the operation parameter of the air conditioner is updated; and when the adjustment times are greater than or equal to the preset times, increasing the temperature of the target indoor heat exchanger of the air conditioner, and controlling the air conditioner to operate according to the increased temperature of the target indoor heat exchanger.
In this embodiment, the preset number of times is a preset threshold value for determining an adjustment number of times of adjusting the operation parameter to be larger, where the preset number of times may be 3 times or 5 times.
Optionally, in an embodiment, when the total adjustment duration is less than the preset duration, acquiring an adjustment frequency for starting to adjust an operation parameter of the air conditioner; judging whether the adjustment times are greater than or equal to preset times, if the adjustment times are greater than or equal to the preset times, judging that the frequency of excessive accumulated water in a water receiving disc of the indoor unit is high, increasing the target indoor heat exchanger temperature of the air conditioner, and controlling the air conditioner to operate according to the increased target indoor heat exchanger temperature; when the adjustment times are smaller than the preset times, the frequency of excessive water accumulation in the water receiving disc of the indoor unit is judged to be low, the air conditioner is controlled to operate at the target indoor heat exchanger temperature, the frequency of excessive water accumulation in the water receiving disc is monitored by judging the adjustment times of the operation parameters of the air conditioner, and therefore when the frequency is high, the temperature of the target indoor heat exchanger is further increased, condensed water is reduced, the water inflow of the water receiving disc is reduced, the situation that the water accumulation in the water receiving disc is excessive when the initial target indoor heat exchanger temperature is still adopted is avoided, and the water accumulation phenomenon of the indoor unit of the air conditioner is avoided.
Alternatively, the increase amount to increase the temperature of the target indoor heat exchanger may be a preset increase amount, such as an increase amount determined according to an operation mode or an increase amount determined according to an operation scenario mode.
Alternatively, the increase of the target indoor heat exchanger temperature may be calculated in real time according to the allowable deviation of the indoor heat exchanger temperature:
if the adjustment times of adjusting the operation frequency of the compressor is greater than or equal to the preset times, acquiring the actual indoor heat exchanger temperature of the air conditioner and the preset indoor heat exchanger temperature operation deviation range; in an embodiment, a reference value in a preset indoor heat exchanger temperature operation deviation range is obtained, and the increase of the target indoor heat exchanger temperature is determined according to the difference value between the actual indoor heat exchanger temperature and the reference value; and then increasing the target indoor heat exchanger temperature according to the increase amount.
In this embodiment, the reference value may be a maximum value of a preset indoor heat exchanger temperature operation deviation range, or may be a minimum value of the preset indoor heat exchanger temperature operation deviation range, or may be any value in the preset indoor heat exchanger temperature operation deviation range.
Thus, acquiring the actual indoor heat exchanger temperature of the air conditioner and presetting the running deviation range of the indoor heat exchanger temperature; according to the difference value between the reference value in the preset indoor heat exchanger temperature operation deviation range and the actual indoor heat exchanger temperature, the increase amount of the target indoor heat exchanger temperature of the air conditioner is determined, and according to the increase amount, the target indoor heat exchanger temperature of the air conditioner is increased, so that the influence of the increase target indoor heat exchanger temperature on indoor comfort level is properly reduced, the air conditioner is balanced between ensuring the indoor comfort level and solving the excessive ponding problem of a water receiving disc, and further the indoor comfort level can be still met after the water soaking risk of the indoor unit is solved, and the functional effect of the air conditioner is optimized.
In addition, the embodiment of the invention also provides a computer readable storage medium, wherein the computer readable storage medium stores a control program of the air conditioner, and the control program of the air conditioner realizes the relevant steps of any embodiment of the control method of the air conditioner when being executed by a processor.
