If condensed water is left in the indoor unit of the air conditioner, moss can grow on the water receiving disc after a period of time, bacteria can grow, and the health of a user is seriously affected; and there is a risk of dripping water after the air conditioner is restarted. The comdenstion water in the current air conditioner passes through the water pump butt joint water dish extracts, however when the comdenstion water production speed increased, original water pump output ability can't satisfy the volume demand of drawing water, and the liquid level increases, and the air conditioner has the risk of dripping.
The invention provides an air conditioner control method. The air conditioner comprises a water pump, the water pump can extract condensed water in a water receiving tray of an indoor unit of the air conditioner, a liquid level switch is arranged in the water receiving tray of the indoor unit of the air conditioner, the liquid level switch is suspended above the water receiving tray and is away from the bottom of the water receiving tray by a preset distance, and the liquid level switch can be fixed by a liquid level switch support. The water pump is not directly connected with the water pan, and the liquid level switch is not directly connected with the water pan. The water pump can be fixed by a water pump support, and the liquid level switch support and/or the water pump support can be arranged on the inner wall of the side plate of the air conditioner, which is vertical to the water pan.
Optionally, the method may be applied to a main control board of an air conditioner indoor unit, the water pump and the liquid level switch are connected to the main control board of the air conditioner indoor unit, and the main control board detects the position of the liquid level switch and controls the operation of the water pump.
Fig. 1 is a schematic method diagram of an embodiment of an air conditioner control method provided by the present invention.
As shown in fig. 1, according to an embodiment of the present invention, the air conditioner control method includes at least step S110 and step S120.
And step S110, detecting whether the liquid level switch arranged in a water pan of the indoor unit leaves an initial position.
And step S120, when the liquid level switch is detected to leave the initial position, controlling the water pump to operate according to the difference value between a preset temperature threshold value and the temperature of the indoor heat exchanger so as to extract condensed water in the water pan.
After the air conditioner operates for a period of time, condensate water can be generated and accumulated in the water pan, and along with the increase of the liquid level height of the condensate water, the liquid level switch in the water pan can be jacked up, so that the liquid level switch leaves the initial position. When the liquid level switch is detected to leave the initial position, the water pump is controlled to start to operate, and condensed water in the water pan is pumped out. Specifically, the temperature of an indoor heat exchanger of the air conditioner may be detected, and the operation of the water pump may be controlled according to a difference between a preset temperature threshold and the temperature of the indoor heat exchanger, so as to extract the condensed water in the water pan.
More specifically, when the difference value is greater than or equal to a first preset temperature value and less than a second preset temperature value, controlling an impeller of the water pump to operate at a first preset rotating speed; when the difference value is greater than or equal to a second preset temperature value and less than a third preset temperature value, controlling an impeller of the water pump to operate at a second preset rotating speed; and when the difference value is greater than or equal to a third preset temperature value, controlling an impeller of the water pump to operate at a third preset rotating speed. The first preset rotating speed is smaller than the second preset rotating speed and smaller than the third preset rotating speed. When the temperature T of the indoor heat exchanger is greater than or equal to the preset temperature threshold T, condensate water appears in the air conditioner, the larger the difference n between T and T is, the more condensate water is generated, and therefore, when the difference n is larger, the larger the impeller rotating speed of the water pump is.
For example, assume that the first preset temperature value is 0 ℃, the second preset temperature value is 1.5 ℃, and the third preset temperature value is 3 ℃. The first preset rotating speed is specifically a preset low-gear rotating speed, the second preset rotating speed is specifically a preset middle-gear rotating speed, and the third preset rotating speed is a preset high-gear rotating speed. Detecting the temperature T of the temperature sensing bulb of the evaporator tube, adjusting the rotating speed of the water pump impeller according to the difference n of T-T, and when n is more than or equal to 0 and less than 1.5 ℃, operating the water pump impeller at a low-gear rotating speed; when n is more than or equal to 1.5 and less than 3 ℃, the water pump impeller runs at a medium rotation speed. When n is more than or equal to 3 ℃, the water pump impeller runs at high-grade rotating speed.
According to the embodiment of the invention, the amount of the condensate water is indirectly judged according to the difference value between the evaporator tube temperature and the preset temperature threshold, the larger the difference value is, the more the condensate water is produced in unit time, the higher the rotating speed of the impeller of the water pump is, the larger the water pumping amount is, so that the water pumping amount of the water pump in unit time can be changed along with the change of the condensate water production amount in unit time, and the phenomenon that the condensate water overflows a water receiving tray to drip because the water pumping amount is insufficient and the condensate water production amount is larger than the water pumping amount can be effectively prevented.
Fig. 2 is a method schematic diagram of another embodiment of the air conditioner control method provided by the invention.
As shown in fig. 2, according to another embodiment of the present invention, the air conditioning control method further includes step S130.
And step S130, controlling whether the water pump stops operating or not according to the working current value of the water pump.
Specifically, if the working current value of the water pump is greater than a preset current threshold, controlling the water pump to continue to operate; and if the working current value of the water pump is less than or equal to a preset current threshold value, controlling the water pump to stop running. The preset current threshold may specifically be a working current value of the water pump during zero-load operation.
When the water pump starts to work, continuously monitoring the working current value a of the water pump; the working current value when the water pump runs at zero load is set as a current threshold value A in advance. The water pump and the water receiving tray have a certain gap. The height of the water level in the water receiving tray determines that the water pump can not pump water. When the water pump runs, if the water pump can not pump water, namely when the water pump runs at zero load, the current value is A; if the water pump can pump water, i.e. the water pump operates with a load, the current value a is larger than the current value A when the water pump operates with a zero load. If the monitored working current value a of the water pump is larger than the current threshold value A, the water pump can pump water, and the water pump continues to operate; if the monitored working current value a is smaller than or equal to the current threshold value A, the water pump can stop running if the water pump can not pump water or can only pump a little water. Preferably, after the air conditioner is turned off, whether the water pump stops operating is controlled according to the working current value of the water pump.
When the air conditioner is shut down for a period of time, the air conditioner does not produce any more condensed water, but the condensed water still remains in the water receiving tray, if the water pump and the air conditioner are shut down together at the moment, the accumulated condensed water cannot be quickly discharged, and if the condensed water is generated for a long time, moss and bacteria exist in the water receiving tray. And when the moment that the working current value is smaller than the preset current threshold value is detected, the impeller of the water pump still operates at the original rotating speed, however, the amount of condensed water in the water receiving tray is already small, and at the moment, if the water pump continues to operate, air and water are sucked into the water pump together to generate noise. Therefore, when the working current value is detected to be smaller than the preset current threshold value, the water pump is controlled to be turned off, and the phenomenon that air and water are sucked into the water pump together to generate obvious water pump working sound if the water pump runs continuously when the amount of condensed water in the water receiving tray is small can be effectively prevented.
For clearly explaining the technical solution of the present invention, the following describes an execution flow of the air conditioner control method provided by the present invention with a specific embodiment.
Fig. 3 is a schematic method diagram of an embodiment of an air conditioner control method according to the present invention. As shown in fig. 3, it is assumed that the first preset temperature value is 0 ℃, the second preset temperature value is 1.5 ℃, and the third preset temperature value is 3 ℃. The first preset rotating speed is a low-gear rotating speed, the second preset rotating speed is a middle-gear rotating speed, and the third preset rotating speed is a high-gear rotating speed. After the air conditioner operates for a period of time in a refrigerating mode, condensate water is generated and accumulated in the water receiving tray, the liquid level switch is jacked along with the increase of the liquid level of the condensate water, and after the liquid level switch is detected to be away from the initial position, the water pump is controlled to start working, and the condensate water in the water receiving tray is pumped out. Adjusting the rotating speed of a water pump impeller according to the difference value n between a preset temperature threshold value T and the temperature T of an evaporator pipe of an indoor unit of an air conditioner, wherein when n is more than or equal to 0 and less than 1.5 ℃, the water pump impeller operates at a low-gear rotating speed; when n is more than or equal to 1.5 and less than 3 ℃, the water pump impeller runs at a medium rotation speed; when n is more than or equal to 3 ℃, the water pump impeller runs at high-grade rotating speed. After the water pump starts to work, the working current value a of the water pump is continuously monitored, and whether the working current value a of the water pump is larger than the zero load current value A of the water pump or not is judged (namely, a preset current threshold value). If the working current value a is larger than the current threshold value A, the water pump continues to operate; and if the working current value a is less than or equal to the current threshold value A, indicating that the water pump can not pump water or can only pump a little water, closing the water pump.
The invention also provides an air conditioner control device. The air conditioner comprises a water pump, the water pump can extract condensed water in a water receiving tray of an indoor unit of the air conditioner, a liquid level switch is arranged in the water receiving tray of the indoor unit of the air conditioner, the liquid level switch is suspended above the water receiving tray and is away from the bottom of the water receiving tray by a preset distance, and the liquid level switch can be fixed by a liquid level switch support. The water pump is not directly connected with the water pan, and the liquid level switch is not directly connected with the water pan. The water pump can be fixed by a water pump support, and the liquid level switch support and/or the water pump support can be arranged on the inner wall of the side plate of the air conditioner, which is vertical to the water pan.
Optionally, the device can be used for a main control board of an air conditioner indoor unit, the water pump and the liquid level switch are connected with the main control board of the air conditioner indoor unit, and the main control board detects the position of the liquid level switch and controls the operation of the water pump.
Fig. 4 is a block diagram of an embodiment of an air conditioning control apparatus according to the present invention. As shown in fig. 4, the air conditioning control device 100 includes a detection unit 110 and a control unit 120.
The detection unit 110 is configured to detect whether the liquid level switch disposed in a water pan of the indoor unit leaves an initial position. The control unit 120 is configured to, when the detection unit 110 detects that the liquid level switch leaves the initial position, control the water pump to operate according to a difference between a preset temperature threshold and a temperature of the indoor heat exchanger, so as to extract condensed water in the water pan.
After the air conditioner operates for a period of time, condensate water can be generated and accumulated in the water pan, and along with the increase of the liquid level height of the condensate water, the liquid level switch in the water pan can be jacked up, so that the liquid level switch leaves the initial position. When the detection unit 110 detects that the liquid level switch leaves the initial position, the water pump is controlled to start to operate, and condensed water in the water pan is pumped out. Specifically, the temperature of an indoor heat exchanger of the air conditioner may be detected, and the operation of the water pump may be controlled according to a difference between a preset temperature threshold and the temperature of the indoor heat exchanger, so as to extract the condensed water in the water pan.
More specifically, when the difference value is greater than or equal to a first preset temperature value and less than a second preset temperature value, controlling an impeller of the water pump to operate at a first preset rotating speed; when the difference value is greater than or equal to a second preset temperature value and less than a third preset temperature value, controlling an impeller of the water pump to operate at a second preset rotating speed; and when the difference value is greater than or equal to a third preset temperature value, controlling an impeller of the water pump to operate at a third preset rotating speed. The first preset rotating speed is smaller than the second preset rotating speed and smaller than the third preset rotating speed. When the temperature T of the indoor heat exchanger is greater than or equal to the preset temperature threshold T, condensate water appears in the air conditioner, the larger the difference n between T and T is, the more condensate water is generated, and therefore, when the difference n is larger, the larger the impeller rotating speed of the water pump is.
For example, assume that the first preset temperature value is 0 ℃, the second preset temperature value is 1.5 ℃, and the third preset temperature value is 3 ℃. The first preset rotating speed is specifically a preset low-gear rotating speed, the second preset rotating speed is specifically a preset middle-gear rotating speed, and the third preset rotating speed is a preset high-gear rotating speed. Detecting the temperature T of the temperature sensing bulb of the evaporator tube, adjusting the rotating speed of the water pump impeller according to the difference n of T-T, and when n is more than or equal to 0 and less than 1.5 ℃, operating the water pump impeller at a low-gear rotating speed; when n is more than or equal to 1.5 and less than 3 ℃, the water pump impeller runs at a medium rotation speed. When n is more than or equal to 3 ℃, the water pump impeller runs at high-grade rotating speed.
According to the embodiment of the invention, the amount of the condensate water is indirectly judged according to the difference value between the evaporator tube temperature and the preset temperature threshold, the larger the difference value is, the more the condensate water is produced in unit time, the higher the rotating speed of the impeller of the water pump is, the larger the water pumping amount is, so that the water pumping amount of the water pump in unit time can be changed along with the change of the condensate water production amount in unit time, and the phenomenon that the condensate water overflows a water receiving tray to drip because the water pumping amount is insufficient and the condensate water production amount is larger than the water pumping amount can be effectively prevented.
Optionally, according to another embodiment of the present invention, the control unit 120 is further configured to: and controlling whether the water pump stops operating or not according to the working current value of the water pump.
Specifically, if the working current value of the water pump is greater than the preset current threshold, the control unit 120 controls the water pump to continue to operate; if the working current value of the water pump is less than or equal to the preset current threshold, the control unit 120 controls the water pump to stop operating. Wherein the preset current threshold comprises: and the working current value of the water pump during zero-load operation.
When the water pump starts to work, continuously monitoring the working current value a of the water pump; the working current value when the water pump runs at zero load is set as a current threshold value A in advance. The water pump and the water receiving tray have a certain gap. The height of the water level in the water receiving tray determines that the water pump can not pump water. When the water pump runs, if the water pump can not pump water, namely when the water pump runs at zero load, the current value is A; if the water pump can pump water, i.e. the water pump operates with a load, the current value a is larger than the current value A when the water pump operates with a zero load. If the monitored working current value a of the water pump is larger than the current threshold value A, the water pump can pump water, and the water pump continues to operate; if the monitored working current value a is smaller than or equal to the current threshold value A, the water pump can stop running if the water pump can not pump water or can only pump a little water. Preferably, after the air conditioner is turned off, whether the water pump stops operating is controlled according to the working current value of the water pump.
When the air conditioner is shut down for a period of time, the air conditioner does not produce any more condensed water, but the condensed water still remains in the water receiving tray, if the water pump and the air conditioner are shut down together at the moment, the accumulated condensed water cannot be quickly discharged, and if the condensed water is generated for a long time, moss and bacteria exist in the water receiving tray. And when the moment that the working current value is smaller than the preset current threshold value is detected, the impeller of the water pump still operates at the original rotating speed, however, the amount of condensed water in the water receiving tray is already small, and at the moment, if the water pump continues to operate, air and water are sucked into the water pump together to generate noise. Therefore, when the working current value is detected to be smaller than the preset current threshold value, the water pump is controlled to be turned off, and the phenomenon that air and water are sucked into the water pump together to generate obvious water pump working sound if the water pump runs continuously when the amount of condensed water in the water receiving tray is small can be effectively prevented.
