Fig. 1 is a schematic method diagram of an embodiment of an air conditioner water fullness protection control method provided by the invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner water full protection control method includes at least steps S110 and S120.
And step S110, detecting the accumulated water amount of the condensed water in a water receiving tray of the tail end equipment of the air conditioner.
Specifically, during normal refrigeration or dehumidification operation of the air conditioning unit, or during mode switching, due to conditions of alternating cold and heat, temperature difference between the internal environment and the external environment and the like, condensate water accumulation is prone to being generated by the air conditioning terminal equipment, at the moment, a water drainage pump is always drained during operation of the air conditioning unit (operated at a preset rotating speed, such as the lowest rotating speed).
And step S120, when detecting that the accumulated water amount of the condensed water in the water receiving tray meets the water full protection condition, starting to execute water full protection.
In some embodiments, the water accumulation comprises: the water level of condensed water in the water receiving tray; the water full protection condition comprises the following steps: the water level of the condensed water in the water receiving tray reaches a preset water level. Optionally, the preset water level includes: more than two preset water levels from low to high. Alternatively, it may be detected by a plurality of sensors, each placed at a different level, whether the level of condensed water in the drip tray reaches a corresponding level.
In some embodiments, detecting that the accumulated water amount of the condensed water in the water-receiving tray meets the water full protection condition includes: and detecting that the water level of the condensed water in the water receiving tray reaches the lowest water level of the more than two water levels. That is, when it is detected that the water level of the condensed water in the water receiving tray reaches the lowest water level of the two or more water levels, it is determined that the accumulated water amount of the condensed water in the water receiving tray satisfies the water full protection condition, and the water full protection is started. For example, 3 water levels from low to high are preset, corresponding to the water full protection conditions 1, 2 and 3 in sequence, and when the water level of the condensed water in the water receiving tray reaches the lowest water level, the water full protection condition 1 is met, and the water full protection is started to be executed.
The water full protection comprises: and controlling the rotating speed of the drainage water pump according to the accumulated water quantity, wherein the accumulated water quantity corresponds to different rotating speeds of the drainage water pump from small to large. Specifically, the preset more than two water levels (the accumulated water amount is increased from less) from low to high correspond to different rotation speeds of the drainage water pump respectively. The rotation speed of the drainage water pump corresponding to more than two water levels from low to high respectively is from low to high. And controlling the rotating speed of the drainage water pump according to the water level of the accumulated water volume in the more than two water levels.
Presetting 3 water levels from low to high, sequentially corresponding to water full protection conditions 1, 2 and 3, and controlling the drainage water pump to operate at a corresponding rotating speed according to the water level reached by the detected water accumulation amount. And the rotating speeds of the drainage water pumps corresponding to more than two water levels from low to high respectively also from low to high. For example, 3 water levels from low to high correspond to three-gear rotating speeds of low, medium and high in sequence, when the water full protection condition 1 is met, the drainage water pump operates at a low rotating speed, when the water full protection condition 2 is met, the drainage water pump operates at a medium rotating speed, and when the water full protection condition 3 is met, the drainage water pump operates at a high rotating speed.
In some embodiments, the drain pump is not turned on when the amount of the condensed water in the water-receiving tray does not satisfy the water-full protection condition, and the drain pump is turned on when the amount of the condensed water in the water-receiving tray satisfies the water-full protection condition.
In some specific embodiments, when the accumulated water amount of the condensed water in the water receiving tray is detected to meet the water full protection condition, the air conditioning unit is controlled to be shut down in a protection mode. Optionally, it is also possible to control water valve shut, fan shut, auxiliary heat shut and/or display a corresponding fault (i.e. water full protection fault).
Preferably, when the accumulated water amount does not reach the highest water level of more than two preset water levels from low to high (for example, the water full protection conditions 1 and 2 are reached), the fan and the water valve do not need to be turned off, and the requirement that the unit can continuously generate accumulated water and can discharge the accumulated water can be met by increasing the rotating speed at the moment. When the accumulated water amount reaches the water full protection condition 3 (reaching the highest water level) of the maximum accumulated water, the water valve and the fan can be closed in consideration of ensuring the accumulated water to be drained as far as possible.
In some embodiments, the water full protection is exited when it is detected that the accumulated water amount of the condensed water in the water receiving tray satisfies the water full protection exit condition. Optionally, the water full protection exit condition comprises: the water level of the condensed water in the water receiving tray is lower than a preset water full protection exit water level. Optionally, the preset water full protection exit water level is equal to the lowest water level of the more than two preset water levels from low to high.
Specifically, when the accumulated water amount of the condensed water in the water receiving tray is detected to meet the water full protection exit condition, if the operation mode of the air conditioner is a refrigeration mode or a dehumidification mode, the drainage water pump is controlled to operate at the lowest rotation speed. Because the air conditioning unit is in refrigeration or dehumidification operation in-process, or mode switching process, because cold and hot alternation, circumstances such as interior external environment difference in temperature, the terminal equipment of air conditioner produces the comdenstion water ponding easily, consequently, the air conditioning unit is in refrigeration or dehumidification operation in-process drainage water pump can keep opening all the time, for example with minimum rotational speed operation. When the water full protection is executed, when the accumulated water amount of the condensed water in the water receiving tray is detected to meet the water full protection exit condition, the drainage water pump can be controlled to continuously operate at the lowest rotating speed.
And if the current operation mode of the air conditioner is a heating mode, an air supply mode or a shutdown state, controlling the drainage water pump to continuously operate at a preset rotating speed for a preset time and then stopping the operation. For example, the water pump is stopped after running for 10min at a low rotating speed, so that accumulated water is discharged as much as possible. For example, the accumulated water is already increased under the original refrigeration or dehumidification condition, and at this time, if the mode is switched to the heating or air supply mode, although the accumulated water is not generated continuously theoretically, the accumulated water is not discharged completely (the shutdown condition is also true), the operation is continued for a period of time, and the accumulated water can be discharged as much as possible.
In some embodiments, after the water full protection is performed for the set protection time, if it is detected that the accumulated water amount of the condensed water in the water receiving tray still does not meet the water full protection exit condition, a fault of the drainage water pump is reported and/or the drainage water pump is stopped.
For example, when the water full protection exit condition is still not met after the accumulated time of the water full protection reaches 2 hours, the fault of the water pump is reported. At the moment, the water pump stops supplying power, the unit does not detect and judge the water full protection any more, and the fault can be cleared only after the power failure is carried out. Under normal conditions, the water discharging speed is higher than the water accumulating speed, the water discharging speed is generally lower than the water full protection exit water level within a certain time, the water full protection exit condition is met, if the water full protection exit water level is still not discharged within a certain time (and the water valve stops working in the protection normal state, theoretically, the water accumulation cannot be increased), at the moment, the possibility of water leakage is considered, or the water pump is stopped to protect the water pump when possible problems occur.
In order to clearly illustrate the technical solution of the present invention, an execution flow of the air conditioner water full protection control method provided by the present invention is described below with a specific embodiment.
Fig. 2 is a schematic method diagram of an embodiment of a full protection control method for air conditioner water provided by the invention. As shown in fig. 2, after the air conditioner terminal device is started, whether the accumulated water amount of the condensed water in the water receiving tray meets the water full protection condition 1 is detected, wherein the accumulated water amount sequentially corresponds to the water full protection conditions 1, 2 and 3 from small to large, when the water full protection condition is not met, the unit normally operates (the refrigeration dehumidification water pump is turned on, the heating air supply water pump is not turned on, the water valve, the fan, the auxiliary heat and the like normally operate), when the accumulated water amount meets the water full protection condition 1, the water full protection is executed, for example, 3 water levels are preset, the rotating speed of the water pump required for water drainage is determined according to the water level reached by the detected accumulated water amount, the water pump is correspondingly adjusted to 3 rotating speeds from small to large according to the detected accumulated water amount (namely, the met water full protection conditions 1, 2 and 3), namely, when the water full protection condition 1 is met, the water pump operates at a low rotating speed, and when the water full protection condition 2 is met, the water pump runs at a high rotating speed, when the water full protection condition 3 is met, the water pump runs at a high rotating speed, the duration time of water full protection is started to be timed, if the water full protection time reaches 2 hours, a fault of the water pump is reported, and the water pump stops running; therefore, in the set protection time (for example, 2 hours) of the water full protection, if the accumulated water is too fast or too much, the rotating speed of the water pump is also accelerated, and otherwise, the rotating speed of the water pump is also slowed down. When the condition that the water full protection exit condition is met is detected, if the current operation mode is a refrigeration or dehumidification mode, the unit recovers to normal operation, and if the current operation mode is a heating, air supply or shutdown state, the water pump is stopped after running for 10min at a low rotating speed, so that accumulated water is discharged as far as possible.
Fig. 3 is a schematic structural diagram of an embodiment of an air conditioner water fullness protection control device provided by the invention. As shown in fig. 3, the control device 100 includes a detection unit 110 and an execution unit 120.
The detection unit 110 is used to detect the amount of the condensed water accumulated in the water pan of the end equipment of the air conditioner.
Specifically, during normal refrigeration or dehumidification operation of the air conditioning unit, or during mode switching, due to conditions of alternating cold and heat, temperature difference between the internal environment and the external environment and the like, condensate water accumulation is prone to being generated by the air conditioning terminal equipment, at the moment, a water drainage pump is always drained during operation of the air conditioning unit (operated at a preset rotating speed, such as the lowest rotating speed).

In some embodiments, the water accumulation comprises: the water level of condensed water in the water receiving tray; the water full protection condition comprises the following steps: the water level of the condensed water in the water receiving tray reaches a preset water level. Optionally, the preset water level includes: more than two preset water levels from low to high. Alternatively, it may be detected by a plurality of sensors, each placed at a different level, whether the level of condensed water in the drip tray reaches a corresponding level.
In some embodiments, the detecting unit 110 detects that the amount of the condensed water in the water-receiving tray satisfies the water full protection condition, and includes: and detecting that the water level of the condensed water in the water receiving tray reaches the lowest water level of the more than two water levels. That is, when the detection unit 110 detects that the water level of the condensed water in the water tray reaches the lowest water level of the two or more water levels, that is, it is determined that the amount of the accumulated water of the condensed water in the water tray satisfies the water full protection condition, the execution unit 120 starts to execute the water full protection. For example, 3 water levels from low to high are preset, corresponding to the water full protection conditions 1, 2 and 3 in sequence, and when the water level of the condensed water in the water receiving tray reaches the lowest water level, the water full protection condition 1 is met, and the water full protection is started to be executed.
The water full protection comprises: and controlling the rotating speed of the drainage water pump according to the accumulated water quantity, wherein the accumulated water quantity corresponds to different rotating speeds of the drainage water pump from small to large. Specifically, the preset more than two water levels (the accumulated water amount is increased from less) from low to high correspond to different rotation speeds of the drainage water pump respectively. The rotation speed of the drainage water pump corresponding to more than two water levels from low to high respectively is from low to high. The execution unit 120 controls the rotation speed of the drainage pump according to the water level at which the accumulated water amount reaches the two or more water levels.
Presetting 3 water levels from low to high, sequentially corresponding to water full protection conditions 1, 2 and 3, and controlling the drainage water pump to operate at a corresponding rotating speed according to the water level reached by the detected water accumulation amount. And the rotating speeds of the drainage water pumps corresponding to more than two water levels from low to high respectively also from low to high. For example, 3 water levels from low to high correspond to three-gear rotating speeds of low, medium and high in sequence, when the water full protection condition 1 is met, the drainage water pump operates at a low rotating speed, when the water full protection condition 2 is met, the drainage water pump operates at a medium rotating speed, and when the water full protection condition 3 is met, the drainage water pump operates at a high rotating speed.
In some embodiments, the drain pump is not turned on when the amount of the condensed water in the water-receiving tray does not satisfy the water-full protection condition, and the drain pump is turned on when the amount of the condensed water in the water-receiving tray satisfies the water-full protection condition.
In some embodiments, the control device 100 further comprises a control unit (not shown). The control unit is configured to control the air conditioning unit to shut down in a protection manner when the detection unit 110 detects that the accumulated water amount of the condensed water in the water receiving tray meets the water full protection condition. Optionally, the control unit may also control water valve shut, air switches, auxiliary heat shut and/or display a corresponding fault (i.e. water full protection fault).
Preferably, when the accumulated water amount does not reach the highest water level of more than two preset water levels from low to high (for example, the water full protection conditions 1 and 2 are reached), the fan and the water valve do not need to be turned off, and the requirement that the unit can continuously generate accumulated water and can discharge the accumulated water can be met by increasing the rotating speed at the moment. When the accumulated water amount reaches the water full protection condition 3 (reaching the highest water level) of the maximum accumulated water, the control unit can close the water valve and the fan in consideration of ensuring the accumulated water to be discharged as far as possible.
In some embodiments, the execution unit 120 is further configured to exit the water-full protection when the detection unit 110 detects that the accumulated water amount of the condensed water in the water-receiving tray meets a water-full protection exit condition. Optionally, the water full protection exit condition comprises: the water level of the condensed water in the water receiving tray is lower than a preset water full protection exit water level. Optionally, the preset water full protection exit water level is equal to the lowest water level of the more than two preset water levels from low to high.
Specifically, when the detection unit 110 detects that the accumulated water amount of the condensed water in the water pan satisfies the water full protection exit condition, if the current operation mode of the air conditioner is a cooling mode or a dehumidification mode, the drainage water pump is controlled to operate at the lowest rotation speed. Because the air conditioning unit is in refrigeration or dehumidification operation in-process, or mode switching process, because cold and hot alternation, circumstances such as interior external environment difference in temperature, the terminal equipment of air conditioner produces the comdenstion water ponding easily, consequently, the air conditioning unit is in refrigeration or dehumidification operation in-process drainage water pump can keep opening all the time, for example with minimum rotational speed operation. When the water full protection is executed, when the accumulated water amount of the condensed water in the water receiving tray is detected to meet the water full protection exit condition, the drainage water pump can be controlled to continuously operate at the lowest rotating speed.
And if the current operation mode of the air conditioner is a heating mode, an air supply mode or a current shutdown state, controlling the drainage water pump to continuously operate at a preset rotating speed for a preset time and then stop operating. The current operation mode is switched from a cooling mode or a dehumidification mode to a heating mode or an air supply mode, or the current operation mode is switched to a shutdown state when the current operation mode is the cooling mode or the dehumidification mode. For example, the water pump is stopped after running for 10min at a low rotating speed, so that accumulated water is discharged as much as possible. For example, the accumulated water is already increased under the original refrigeration or dehumidification condition, and at this time, if the mode is switched to the heating or air supply mode, although the accumulated water is not generated continuously theoretically, the accumulated water is not discharged completely (the shutdown condition is also true), the operation is continued for a period of time, and the accumulated water can be discharged as much as possible.
In some embodiments, the control device 100 further includes a processing unit (not shown) configured to, after performing the water full protection for the set protection time, report a fault of the drain water pump and/or stop operation of the drain water pump if it is detected that the accumulated water amount of the condensed water in the water receiving tray still does not satisfy the water full protection exit condition.
For example, when the water full protection exit condition is still not met after the accumulated time of the water full protection reaches 2 hours, the fault of the water pump is reported. At the moment, the water pump stops supplying power, the unit does not detect and judge the water full protection any more, and the fault can be cleared only after the power failure is carried out. Under normal conditions, the water discharging speed is higher than the water accumulating speed, the water discharging speed is generally lower than the water full protection exit water level within a certain time, the water full protection exit condition is met, if the water full protection exit water level is still not discharged within a certain time (and the water valve stops working in the protection normal state, theoretically, the water accumulation cannot be increased), at the moment, the possibility of water leakage is considered, or the water pump is stopped to protect the water pump when possible problems occur.

The invention also provides an air conditioner corresponding to the air conditioner water full protection control method, which comprises a processor, a memory and a computer program which is stored on the memory and can run on the processor, wherein the processor realizes the steps of any one of the methods when executing the program.
The invention also provides an air conditioner corresponding to the air conditioner water fullness protection control device, which comprises any one of the air conditioner water fullness protection control devices.
Therefore, according to the scheme provided by the invention, the rotating speed of the drainage water pump of the water receiving tray is controlled according to the accumulated water amount of the condensed water in the water receiving tray, so that the drainage control of the water receiving tray is realized, and the energy is saved and the consumption is reduced. Meanwhile, the rotating speed of the drainage water pump of the water receiving tray is controlled according to the accumulated water amount, the water pump can operate at a lower rotating speed when the accumulated water amount is lower, and the water pump correspondingly operates at a higher rotating speed when the accumulated water amount is higher, so that the problem of indoor noise can be reduced. In addition, by accumulating the execution water full protection time, after the water full protection is continuously set for the protection time, the water full protection exit condition is still not met, the fault of the water pump is reported, the energy conservation can be realized, and the energy waste caused by long-term operation of the water pump under the fault condition is avoided.
