Referring first to fig. 1, the drain device for an integrated air conditioner of the present invention will be described. Fig. 1 is a schematic structural view of an integrated air conditioner having a drain device.
As shown in fig. 1, in order to solve the problem that the drainage manner of the condensed water in the prior art cannot meet the requirement of the drainage of the condensed water in the integrated air conditioner, the drainage device 1 for the integrated air conditioner of the present invention comprises a water storage tank 11, a drainage pump 12 and a water level detector 13 for detecting the water level in the water storage tank 11, wherein the drainage pump 12 and the water level detector 13 are respectively arranged in the water storage tank 11, the drainage pump 12 is connected with a drainage pipe 121, and the drainage pipe 121 can drain the condensed water in the water storage tank 11 to the condenser 2 of the integrated air conditioner.
The drainage device 1 for the integrated air conditioner of the invention is arranged as above to detect the water level in the water storage tank 11 and drain the condensed water in the water storage tank 11 to the condenser 2 of the integrated air conditioner through the drainage pump 12, and evaporate the condensed water through the condenser 2 to meet the drainage requirement of the integrated air conditioner for the condensed water.
It should be noted that the water level detector 13 in this embodiment is a floating water level detector or a multi-probe water level detector.
The drain device for an integral type air conditioner of the present invention will be described in detail with further reference to fig. 2.
In one possible embodiment, as shown in fig. 2, the water level detector 13 comprises a first probe 131, a second probe 132 and a third probe 133 capable of detecting different water levels in the water storage tank 11, respectively, the length of the first probe 131 being greater than the length of the second probe 132, and the length of the second probe 132 being greater than the length of the third probe 133.
In the embodiment, the water level detector 13 with the first probe 131, the second probe 132 and the third probe 133 with different lengths can detect different gradients of the water level in the water storage tank 11, so that hardware support is provided for the intelligent drainage of condensed water by setting a related control method.
As shown in fig. 1-3, the present invention further provides a control method of a drainage device for an integrated air conditioner, the drainage device 1 includes a water storage tank 11, a drainage pump 12 and a water level detector 13 for detecting the water level in the water storage tank 11, the drainage pump 12 and the water level detector 13 are respectively disposed in the water storage tank 11, a drainage pipe 121 is connected to the drainage pump 12, and the drainage pipe 121 can drain the condensed water in the water storage tank 11 to a condenser 2 of the integrated air conditioner; the control method comprises the following steps:
s01: controlling a water level detector to detect whether the water level in the water storage tank reaches a drainage water level and whether the water level in the water storage tank reaches a quick drainage water level;
wherein the height of the fast drain water level is higher than that of the drain water level.
Specifically, the water discharge apparatus 1 detects the water level in the water storage tank 11 by controlling the water level detector 13, and determines whether the water level in the water storage tank 11 reaches the water discharge level and the quick water discharge level according to the detection result of the water level detector 13.
S02: selectively controlling the integrated air conditioner not to drain, entering a normal drainage mode or entering an accelerated drainage mode based on the detected height of the water level in the water storage tank;
wherein the drainage speed of the normal drainage mode is less than that of the accelerated drainage mode.
Specifically, the water level condition in the water storage tank 11 is detected based on the water level detector 13, and the integrated air conditioner is controlled not to drain, enters a normal drainage mode or enters an accelerated drainage mode according to different water level conditions.
As shown in fig. 1-3, in one possible embodiment, the step S02 of selectively controlling the integrated air conditioner not to drain, enter the normal drainage mode or enter the accelerated drainage mode based on the detected height of the water level in the storage tank "includes the steps of:
s021: when the water level does not reach the first probe, the drainage is not executed;
specifically, when the water level in the water storage tank 11 does not reach the first probe 131, the water level detector 13 does not detect the water level signal at this time, which indicates that the water level in the water storage tank 11 is low at this time, and the water drainage may not be performed, and thus, the integrated air conditioner is controlled not to perform the water drainage.
S022: when the water level reaches the first probe and does not reach the second probe, entering a normal drainage mode;
specifically, when the water level in the water storage tank 11 reaches the first probe 131 but does not reach the second probe 132, only the first probe 131 in the water level detector 13 can detect a water level signal, which indicates that a certain amount of condensed water is accumulated in the water storage tank 11 at this time, but the accumulated amount of the condensed water in the water storage tank 11 is still at a normal level at this time, and therefore, the integrated air conditioner is controlled to enter the normal drainage mode.
As shown in fig. 4, the normal drainage mode is:
s0221: controlling the drainage pump to pump water, controlling a compressor of the integrated air conditioner to run at a rated frequency, and controlling an outdoor fan of the integrated air conditioner to run at a rated wind speed until the water level is up to the state of the first probe again;
specifically, when the water level detector 13 detects that a certain amount of condensed water has been accumulated in the water storage tank 11, but the accumulated amount of condensed water is still at a normal level, there is no need to adjust the frequency of the compressor 3 and the air speed of the outdoor fan 4 of the integrated air conditioner, so that the drainage device 1 controls the drainage pump 12 to pump water, controls the compressor 3 of the integrated air conditioner to operate at a rated frequency, and controls the outdoor fan 4 of the integrated air conditioner to operate at a rated air speed until the water level is again lower than the first probe 131.
Wherein, the step S0221 of controlling the drain pump to pump water may further include: controlling the drainage pump to pump water after delaying the first set time;
specifically, when the water level detector 13 detects that the water level in the water storage tank 11 reaches the state of the first probe 131, the drainage device 1 controls the drainage pump 12 to pump water after delaying for a first set time. The above arrangement can prevent the drainage pump 12 from being turned on due to the misjudgment of the water level detector 13 in the water storage tank 11, and on the other hand, when the water level in the water storage tank 11 just reaches the state of the first probe 131, the accumulation amount of the condensed water in the water storage tank 11 is relatively small, and the accumulation amount of the condensed water in the water storage tank 11 can be relatively increased by delaying the water pumping after the first set time, and at this time, the drainage efficiency of the drainage pump 12 in the process of once drainage of the condensed water can be improved by controlling the drainage pump 12 to pump water, so as to reduce the times of repeatedly turning on the drainage pump 12. In the present invention, the first set time is preferably 10 minutes.
S0222: and controlling the drainage pump to stop pumping water.
Specifically, when the water level in the water storage tank 11 drops below the first probe 131 again after the condensed water in the water storage tank 11 is pumped by the water discharge pump 12, it is described that the water level in the water storage tank 11 has dropped to a lower level at this time, and the water discharge is no longer needed, so the water discharge pump 12 is controlled to stop pumping water.
After the step S0222 of "controlling the drainage pump to stop the water pumping", the control method may further include: the drainage pump is not started within the second set time.
Specifically, when the drainage device 1 controls the drainage pump 12 to perform one-time drainage of the condensed water accumulated in the water storage tank 11, and controls the drainage pump 12 to stop the drainage in a state where the water level of the condensed water in the water storage tank 11 has fallen below the first probe 131, the drainage pump 12 is not turned on for the second set time. In the present invention, the second set time is preferably 10 minutes. So far, the introduction of the normal drainage mode is finished.
S023: and when the water level reaches the second probe, entering an accelerated drainage mode.
Specifically, when the water level in the water storage tank 11 reaches the state of the second probe 132, the second probe 132 in the water level detector 13 can detect the water level signal in the water storage tank 11, which indicates that more condensed water has accumulated in the water storage tank 11 at this time, and in order to ensure the normal operation of the integrated air conditioner, the condensed water accumulated in the water storage tank 11 needs to be quickly drained, so that the integrated air conditioner is controlled to enter the accelerated drainage mode.
As shown in fig. 5, the accelerated drainage mode is:
s0231: controlling the drainage pump to pump water;
s0232: controlling a compressor of the integrated air conditioner to operate at a frequency lower than a first set multiple of a rated frequency, and/or controlling an outdoor fan of the integrated air conditioner to operate at a rotating speed higher than a second set multiple of the rated rotating speed until the water level is in a state of not reaching the first probe again;
s0233: controlling the drainage pump to stop pumping water;
specifically, when the water level in the water storage tank 11 reaches the state of the second probe 132, at this time, more condensed water is accumulated in the water storage tank 11, and in order to quickly discharge the condensed water in the water storage tank 11, it is not enough to control only the drain pump 12 to pump water, and therefore, the compressor 3 of the integrated air conditioner is controlled to operate at a frequency lower than the first set multiple of the rated frequency while the drain pump 12 is controlled to pump water, and/or the outdoor fan 4 of the integrated air conditioner is controlled to operate at a rotational speed higher than the second set multiple of the rated rotational speed until the water level reaches the state of not reaching the first probe 131 again. Through the arrangement mode, the condensate water in the water storage tank 11 can be pumped and drained, and meanwhile, the generation amount of the condensate water is reduced, so that the effect of quickly reducing the condensate water in the water storage tank 11 is achieved. When the water level in the water storage tank 11 is lowered below the first probe 131 again by the above control method, it means that the accumulated amount of condensed water in the water storage tank 11 has been reduced to a small level, and therefore the drain pump 12 is controlled to stop pumping water. Wherein the first set multiple is between 0.7 and 0.9, more preferably 0.8; the second set multiple is between 1.05 and 1.15, more preferably 1.1.
S0234: and controlling a compressor of the integrated air conditioner to be adjusted to the rated frequency for operation, and/or controlling an outdoor fan of the integrated air conditioner to be adjusted to the rated wind speed for operation.
Specifically, when the water level in the water storage tank 11 drops below the first probe 131 again, which indicates that the pumping of the condensed water in the water storage tank 11 is completed by the above control method, in order to further ensure the operation effect of the integrated air conditioner, the compressor 3 of the integrated air conditioner is controlled to operate at the rated frequency, and/or the outdoor fan 4 of the integrated air conditioner is controlled to operate at the rated wind speed.
As shown in fig. 1-2, in one possible embodiment, the step S02 of selectively controlling the integrated air conditioner to not drain, enter the normal drainage mode, or enter the accelerated drainage mode based on the detected height of the water level in the water storage tank "further comprises a third probe 133 capable of detecting a rapid drainage water level in the water storage tank 11, the rapid drainage water level being higher than the rapid drainage water level: and selectively controlling the integrated air conditioner not to drain, entering a normal drainage mode, entering an accelerated drainage mode or entering a rapid drainage mode based on the detected height of the water level in the water storage tank.
Wherein, when the water level reaches the third probe, the rapid drainage mode is entered.
Specifically, in order to further secure the safe operation of the integrated air conditioner, a third probe 133 for detecting the rapid water discharge level in the water storage tank 11 is added to the water level detector 13. And controls the integrated air conditioner to enter a rapid drainage mode when the water level in the storage tank 11 reaches the state of the third probe 133.
As shown in fig. 6, the rapid drainage mode is:
s0241: controlling a compressor of the integrated air conditioner to stop and controlling an outdoor fan of the integrated air conditioner to operate;
s0242: controlling the drainage pump to pump water until the water level reaches the state of the second probe again;
specifically, when the water level in the water storage tank 11 reaches the state of the third probe 133, it is described that a large amount of condensed water is accumulated in the water storage tank 11 at this time, and the large amount of condensed water accumulated in the water storage tank 11 needs to be rapidly discharged, and at this time, only the drainage pump 12 is controlled to pump water, which cannot meet the drainage requirement, so that the compressor 3 of the integrated air conditioner needs to be controlled to stop, the outdoor fan 4 of the integrated air conditioner is controlled to operate, and meanwhile, the drainage pump 12 is controlled to pump water until the water level reaches the state of the second probe 132 again. According to the arrangement mode, the compressor 3 of the integrated air conditioner is controlled to stop, so that the generation of condensed water is fundamentally stopped, the outdoor fan 4 of the integrated air conditioner is controlled to operate, the drainage pump 12 is controlled to pump water, and the effect of rapidly discharging the condensed water in the water storage tank 11 can be achieved.
Wherein, the step S0242 of controlling the drainage pump to pump water until the water level reaches the state that the second probe is not reached again further includes: controlling the drainage pump to pump water;
when the water level still can not reach the state of the second probe again after the third set time, controlling the integrated air conditioner to stop and sending a signal of water pump failure;
