The current values of the drainage pump in the air conditioner indoor unit during idling and on-load operation are different, so that the operation of the drainage pump can be controlled according to the operation current value of the drainage pump in an operation state and the opening and closing state of the float switch in the drainage pump in the embodiment of the disclosure, the idling probability of the drainage pump can be reduced, the control accuracy of the air conditioner drainage pump is improved, and the service life of the drainage pump is prolonged.
Fig. 1 is a schematic flow chart of a control method for an air conditioner drainage pump according to an embodiment of the disclosure. As shown in fig. 1, the process of air conditioner drain pump control includes:
step 101: and acquiring the current running current value of the drainage pump in the running state in the indoor unit of the air conditioner.
The drainage pump is a component of the indoor unit of the air conditioner, and when the air conditioner operates in a refrigerating mode, condensed water in the indoor unit is accumulated in the water receiving disc, so that the drainage pump in the indoor unit of the air conditioner is started after the time is generally delayed by N1min when the air conditioner operates in the refrigerating mode, namely, the drainage pump is controlled to be in an operating state after the time is delayed by a first set time under the condition of the starting operation in the refrigerating mode of the air conditioner. When the air conditioner is in heating operation, the indoor unit generally does not have condensed water accumulation. Therefore, when the air conditioner is started to perform heating operation, the drain pump is not started for the moment.
The air-conditioning indoor unit can be provided with a current detection device, for example: the current transformer can acquire the running current value of the drainage pump in the running state in real time or at regular time once the drainage pump is in the running state, and the running current value acquired at the current moment can be the current running current value.
Step 102: and controlling the drainage pump to be in a stop state under the condition that the current operation current value is smaller than the set value.
The current values of the drainage pump during idle running and on-load running are different, so that a set value A can be determined according to the performance of the air conditioner, the performance of the drainage pump and the like, wherein the current value of the current running is smaller than the set value A, the drainage pump can be in idle running, and the drainage pump can be controlled to be in a stop state when the drainage pump needs to stop running. Of course, if the current value of the current operation current is greater than or equal to the set value a, the drain pump may be in an on-load operation, that is, the water in the water receiving tray is drained, and therefore, the drain pump can be controlled to be in an operation state.
Step 103: and under the condition that the drainage pump is in a stop state, acquiring the current opening and closing state information of a float switch in the drainage pump.
The drain pump includes a float switch, which is normally closed, and once the water in the water pan reaches a set position, for example: when the water is full, the float switch is off, i.e. in an off state. Therefore, the open/close state information of the float switch includes: closed state, open state.
When the air conditioner is started to start and perform heating operation, the drainage pump cannot be started temporarily, namely the drainage pump is in a stop state; alternatively, the drain pump is operated, but the operation current value at the time of operation is smaller than the set value, the drain pump is also in the stopped state, and therefore, the drain pump may be in the stopped state in two or more scenes.
In the embodiment of the present disclosure, when the drain pump is in the stop state, the current opening and closing state information of the float switch in the drain pump can be acquired in a timed or real-time manner, wherein the current opening and closing state information includes: closed state, open state.
Step 104: and controlling the drainage pump to be in the running state under the condition that the current opening and closing state information is in the off state.
In a typical indoor unit of an air conditioner, water in a water receiving tray reaches a set position, for example: when the water is full, the float switch is turned off, namely, is in an off state, so that when the current opening and closing state information of the float switch is in the off state, the fact that the indoor unit of the air conditioner needs to drain water can be indicated, and therefore, the drainage pump needs to be started, namely, the drainage pump is controlled to be in an operating state.
When the air conditioner starts heating operation, the drainage pump is not started temporarily, namely the drainage pump is in a stop state, once the current opening and closing state information is determined to be in a disconnection state, the drainage pump can be started, and the drainage pump is enabled to be in a running state.
When the air conditioner operates in a refrigerating mode, the drainage pump does not need to work all the time, when the current value corresponding to the operation state is smaller than the set value A, the drainage pump is also in a stop state, if the detected current opening and closing state information is in a disconnection state, the drainage pump is required to be started, and therefore the drainage pump is in the operation state.
Therefore, in the embodiment, by monitoring the running current value of the drainage pump in the running state, the idling probability of the drainage pump can be reduced, and the service life of the drainage pump is prolonged; and through monitoring the state of opening and shutting of float switch, can ensure the drainage function of drain pump to can improve the accuracy nature of air conditioner drain pump control.
Of course, after step 104, the drainage pump is in a running state, then in some embodiments, step 101 may be executed to monitor a running current value of the drainage pump in the running state, so that if the monitored running current value is smaller than the set value a, the drainage pump may be controlled to be in a stopped state, and the operation of the drainage pump may be continuously controlled by monitoring the opening and closing state of the float switch.
Generally, when an air conditioner drainage pump normally operates, water in a water receiving tray can be drained through operation of the drainage pump twice or set times, however, after operation of the drainage pump twice or set times, if the monitored opening and closing state of a float switch is still in an off state, it is indicated that the float switch is possibly blocked or has other faults, and fault prompt needs to be carried out, so that in some embodiments, when the current opening and closing state information is in the off state, the current opening and closing state information is updated to be the continuous times of the off state; and when the continuous times are larger than the set times, the drainage pump fault prompting treatment is carried out.
When the current opening and closing state information of the float switch in the drainage pump is in the off state, the continuous times that the recorded current opening and closing state information is in the off state can be updated. For example: if the current opening and closing state information of the float switch is determined to be in the off state for the first time, the recorded duration times are 1, and if the current opening and closing state information of the float switch is determined to be in the off state for the current time and the current opening and closing state information of the float switch is also determined to be in the off state for the previous time, namely the last time, the recorded duration times are required to be +1.
Similarly, the set times can be determined according to the performance of the air conditioner and the drainage pump, the operation geographical position, the season and the like, and can be 1, 2, 3 or 5, and the like, so that if the updated continuous times are more than the set times, the probability of the float switch having the fault is indicated, and the drainage pump fault prompting treatment is required.
Of course, there are various ways to perform the drain pump malfunction notification process, including: the system comprises one or more of photoelectric reminding, voice reminding, image-text reminding, reminding for sending reminding information to a user binding terminal and the like.
If the opening and closing state information corresponding to the previous time is in the opening state, but the current opening and closing state information corresponding to the current time is in the closing state, the continuous times need to be cleared. So that the drain pump malfunction cue process can continue to operate.
In some embodiments, when the drainage pump is in the stop state, the detected information of the current open/close state of the float switch is in the closed state, and the operation of the air conditioner may be controlled according to the operation mode of the air conditioner. If the air conditioner cooling mode is operated, the second set time can be delayed, the drainage pump is controlled to be in the running state, and if the air conditioner heating mode is operated, the drainage pump can be controlled to be kept in the stopping state.
When the air conditioner operates in a refrigerating mode, condensed water is accumulated in the water receiving disc in the indoor unit, therefore, the current opening and closing state information of the float switch is in a closed state, and only the fact that water in the water receiving disc does not reach the set height or is not full can be indicated, however, water still exists in the water receiving disc, and therefore after N2min can be delayed, the drainage pump is started, and the drainage pump is enabled to be in an operating state.
In some embodiments, when the drain pump is in the operating state, if an air conditioner shutdown instruction is received, that is, it is determined that the air conditioner needs to be shutdown, at this time, the drain pump may still be in the operating state, and the drain pump is not turned off until the detected operating current is less than the set value a. If the drainage pump is in a stop state, the drainage pump is controlled to maintain the stop state under the condition that the air conditioner is in shutdown operation, namely the drainage pump still maintains the stop state after receiving an air conditioner shutdown instruction.
The following operational procedures are integrated into an embodiment to illustrate the control process for the air conditioner drainage pump provided by the embodiment of the invention.
In an embodiment of the present disclosure, a current transformer is configured in the indoor unit of the air conditioner, and is capable of detecting an operation current value of the drainage pump, where a first set time is N1min, a second set time is N2min, and a set value is a. The number of times was set to 2.

Step 206: and controlling the drainage pump to be in a stop state.
Step 207: and acquiring the current opening and closing state information of a float switch in the drainage pump.
Step 208: determine whether the current open/close status information is in the open status? If so, go to step 209, otherwise go to step 212.
Step 209: and updating the current opening and closing state information into the continuous times of the disconnection state.
Step 210: determine if the duration >2 is true? If yes, go to step 211, otherwise, go back to step 203.

Step 212: and clearing the duration times.
Step 213: determine whether a second duration corresponding to the drain pump being in a stopped state reaches N2min? If yes, go back to step 203, otherwise, go back to step 213.
Therefore, in the embodiment, when the air conditioner operates in a refrigerating mode, the drainage pump can be controlled to operate periodically according to the detected operation current of the drainage pump, so that the idling probability of the drainage pump is reduced, the refrigerating and drainage functions are guaranteed, resources are saved, the drainage pump can be started in time to drain water in time once the float switch is switched off, the accuracy of control over the air conditioner drainage pump is improved, in addition, fault prompt can be carried out in time, and the service life of the drainage pump is prolonged.
In an embodiment of the present disclosure, a current transformer is configured in an indoor unit of an air conditioner, and is capable of detecting an operating current value of a drainage pump, where a set value is a and a set number of times is 3.

Step 311: and resetting the continuous times and returning to the step 302.
Therefore, in the embodiment, when the air conditioner is in heating operation, once the float switch is turned off, the drainage pump can be started in time to drain water in time, so that the use of the air conditioner is further ensured, and the operation of the drainage pump is controlled according to the detected operation current of the drainage pump, so that the idling probability of the drainage pump is reduced. In addition, the fault prompt can be carried out in time, and the service life of the drainage pump is prolonged.
In addition, no matter the air conditioner is in refrigeration operation or heating operation, once a shutdown instruction is received, the switch of the drainage pump needs to be controlled according to the current state of the drainage pump, wherein if the shutdown instruction is received, the drainage pump is in the operation state, the operation current of the drainage pump needs to be continuously detected, and the drainage pump is not closed until the detected current value is smaller than a set value. If the drainage pump is in a stop state when the shutdown instruction is received, the drainage pump is required to be continuously maintained in the stop state.

Thus, the open-close acquisition module 430 can acquire the current open-close state information of the float switch in the drain pump in the case where the drain pump is in the stopped state.
And the second control module 440 controls the drain pump to be in the operation state when the current open/close state information is the off state. Moreover, when the current open-close state information is in the off state, the current open-close state information is updated to the number of continuous times of the off state, and when the number of continuous times is greater than the set number of times, the fault reminding module 450 can perform the drainage pump fault reminding processing. Of course, when the current opening/closing state information is the closing state, the zero clearing module 460 needs to zero the number of times of the duration, and when the second duration corresponding to the drainage pump being in the stop state reaches N2min, the second delay control module 480 may control the drainage pump to be in the operating state.
Of course, if the drain pump is in the operating state when the shutdown command is received, the third control module 490 needs to continue to detect the operating current of the drain pump, and the drain pump is not shut down until the detected current value is smaller than the set value. If the drain pump is stopped when the shutdown command is received, the third control module 490 needs to keep the drain pump stopped.
Therefore, in the embodiment, the air conditioner is in refrigeration operation, and the device for controlling the air conditioner draining pump controls the draining pump to periodically operate according to the detected operation current of the draining pump, so that the idling probability of the draining pump is reduced, the refrigeration draining function is guaranteed, resources are saved, the draining pump can be started in time once the float switch is switched off, draining is performed in time, the accuracy of control of the air conditioner draining pump is improved, in addition, fault prompt can be performed in time, and the service life of the draining pump is prolonged.
