Description

Technical Field

[0001] This application relates to the field of air conditioners, and more particularly to a control method, apparatus, equipment, medium, and product for an air conditioner. Background Technology

[0002] When an air conditioner is running in cooling or dehumidifying mode, condensate will be generated inside the air conditioner. Therefore, a water storage device (also known as a water collection pan) is installed at the bottom of the air conditioner to store the condensate generated during operation. The condensate stored in the water storage device is usually drained by a slope or by a water pump.

[0003] Due to installation limitations, the drain outlet of the air conditioner's drain pipe may be higher than the outlet of the water storage device. In this case, the condensate stored in the water storage device cannot be drained using a slope drainage method and must be drained by a water pump. In such situations, to reduce energy consumption and eliminate noise from the water pump, the relevant technology typically stops the water pump when it is determined that drainage is no longer needed. However, at this point, there is still condensate remaining in the drain pipe. After the pump stops, due to the water level difference in the drain pipe, a large amount of condensate will quickly backflow into the water storage device, producing a rinsing sound and affecting the user experience. Summary of the Invention

[0004] In view of this, embodiments of this application provide a control method, apparatus, device, medium, and product for an air conditioner, which aims to eliminate the noise generated by a large amount of condensate backflow when the water pump finishes draining.

[0005] The technical solution of this application embodiment is implemented as follows:

[0006] In a first aspect, embodiments of this application provide a control method for an air conditioner. The air conditioner includes a water storage device, a water pump, and a drain pipe. The water storage device is used to store condensate generated during the operation of the air conditioner, and the water pump is used to discharge the condensate from the water storage device into the drain pipe. The method includes:

[0007] When the air conditioner is in cooling mode or dehumidification mode, the current water level in the water storage device is obtained.

[0008] If it is determined that the current water level in the water storage device is higher than the first set water level, then the water pump is controlled to start running at the first speed.

[0009] If the conditions for exiting drainage are met, the water pump will be controlled to reduce its speed.

[0010] If it is determined that there is no condensate stored in the drainage pipe, the water pump is controlled to stop operating.

[0011] In some implementations, determining that the conditions for exiting drainage are met, and then controlling the operating water pump to reduce its speed, includes:

[0012] If it is determined that the current water level in the water storage device is lower than the second set water level, then the operating water pump is controlled to reduce its speed; and / or, in response to an air conditioner shutdown command, the operating water pump is controlled to reduce its speed.

[0013] Wherein, the first set water level is higher than the second set water level.

[0014] In some implementations, a pressure detection unit is installed on the drainage pipeline to detect the lowest water pressure in the drainage pipeline. Controlling the operating water pump to reduce its speed includes:

[0015] Based on a set time interval, the pressure value detected by the pressure detection unit is obtained;

[0016] If it is determined that the pressure value is greater than the set pressure threshold, then the water pump is controlled to run at a second speed within the set time interval;

[0017] The second rotational speed is less than the first rotational speed.

[0018] In some implementations, determining that there is no stored condensate in the drain pipe and then controlling the water pump to stop operating includes:

[0019] If the pressure value is determined to reach the set pressure threshold, the water pump is controlled to stop operating.

[0020] In some implementations, the control of the pump during operation to reduce its speed includes:

[0021] The water pump is controlled to operate in a gradually decreasing speed mode;

[0022] In the progressive speed reduction mode, the pump's rotational speed includes multiple set rotational speeds, each of which corresponds one-to-one with the pump's operating time in the progressive speed reduction mode. The pump operates in the progressive speed reduction mode, including:

[0023] Control the water pump to operate at the third speed;

[0024] If it is determined that the water pump has been running at the current set speed for the corresponding duration, then the speed of the water pump is controlled to be reduced to the next set speed.

[0025] The third speed is the maximum set speed in the step-down speed mode, and the third speed is less than the first speed.

[0026] In some implementations, determining that there is no stored condensate in the drain pipe and then controlling the water pump to stop operating includes:

[0027] If it is determined that the water pump operates in the step-down speed mode for a first duration, then the water pump is controlled to stop operating.

[0028] Secondly, embodiments of this application provide a control device for an air conditioner, the air conditioner including a water storage device, a water pump, and a drain pipe, the water storage device being used to store condensate generated during the operation of the air conditioner, and the water pump being used to discharge the condensate in the water storage device into the drain pipe, the control device including:

[0029] The acquisition module is used to acquire the current water level in the water storage device when the air conditioner is running in cooling mode or dehumidification mode.

[0030] The first control module is used to determine that if the current water level in the water storage device is higher than a first set water level, then control the water pump to start running at a first speed; and if it determines that the conditions for exiting drainage are met, then control the running water pump to reduce its speed.

[0031] The second control module is used to determine that there is no stored condensate in the drainage pipe, and then control the water pump to stop running.

[0032] Thirdly, embodiments of this application provide an air conditioner, which includes a water storage device, a water pump, and a drain pipe. The water storage device is used to store condensate generated during the operation of the air conditioner, and the water pump is used to discharge the condensate in the water storage device into the drain pipe. The air conditioner further includes a processor and a memory for storing computer programs capable of running on the processor.

[0033] When the processor is used to run a computer program, it performs the steps of the method as described in the first aspect.

[0034] Fourthly, embodiments of this application provide a computer storage medium storing a computer program, which, when executed by a processor, implements the steps of the method described in the first aspect.

[0035] Fifthly, embodiments of this application provide a computer program product, including a computer program that, when executed by a processor, implements the steps of the method described in the first aspect.

[0036] This application provides a control method for an air conditioner, wherein the air conditioner includes a water storage device, a water pump, and a drainage pipe. The water storage device is used to store condensate generated during the operation of the air conditioner, and the water pump is used to discharge the condensate in the water storage device into the drainage pipe. The method includes: when the air conditioner is running in cooling mode or dehumidification mode, obtaining the current water level in the water storage device; if it is determined that the current water level in the water storage device is higher than a first set water level, then controlling the water pump to start running at a first speed; if it is determined that the drainage exit condition is met, then controlling the water pump to reduce its speed; if it is determined that there is no stored condensate in the drainage pipe, then controlling the water pump to stop running. Thus, in this embodiment, the water pump is controlled to start drainage based on the current water level in the water storage device. After determining that the water pump can exit the drainage mode, the water pump is controlled to run at a reduced speed to ensure that the condensate in the drainage pipe slowly flows back to the water storage device. After all the condensate in the drainage pipe has flowed back, the water pump is controlled to stop running. This eliminates the scouring noise caused by a large amount of condensate rapidly flowing back into the water storage device when the water pump stops running. At the same time, it avoids the water pump from running continuously and generating noise when the water level in the water storage device is low, thus improving the user experience.

[0045] The present application will now be described in further detail with reference to the accompanying drawings and embodiments.

[0046] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0047] This application provides a control method for an air conditioner, wherein the air conditioner includes a water storage device, a water pump, and a drain pipe. The water storage device is used to store condensate generated during the operation of the air conditioner, and the water pump is used to discharge the condensate from the water storage device into the drain pipe. Figure 1 As shown, the method includes:

[0048] Step 101: When the air conditioner is running in cooling mode or dehumidification mode, obtain the current water level in the water storage device.

[0049] Step 102: If the current water level in the water storage device is determined to be higher than the first set water level, then control the water pump to start running at the first speed.

[0050] Step 103: If the conditions for exiting drainage are met, control the running water pump to reduce its speed.

[0051] Step 104: If it is determined that there is no condensate stored in the drain pipe, then control the water pump to stop running.

[0052] It should be noted that when an air conditioner is running in cooling or dehumidifying mode, a large amount of condensate is generated in the heat exchanger inside the air conditioner. Therefore, a water storage device is installed at the bottom of the air conditioner to store the condensate generated during operation. In order to drain the condensate in the water storage device to the outside and prevent it from overflowing, a slope drainage or water pump drainage method is usually used.

[0053] Here, as Figure 2 As shown, in the slope drainage method, the drain outlet of the drainage pipe is lower than the outlet of the water storage device. Utilizing the water level difference, the condensate in the water storage device can be directly discharged to the outside through the drainage pipe.

[0054] It should be noted that due to limitations in the installation location of the air conditioner, there are situations where the drain outlet of the drain pipe cannot be positioned lower than the outlet of the water storage device. For example... Figure 3 As shown, the drain outlet of the drain pipe 300 is higher than the outlet of the water storage device. The air conditioner cannot use the slope drainage method to drain the condensate in the water storage device, and can only use the water pump to drain it.

[0055] In related technologies, to avoid unnecessary energy consumption from continuous pump operation and to eliminate noise generated by the pump when the water level in the storage tank is low, the pump's operation is typically controlled based on the current water level in the storage tank. When the water level is high, the pump is started to prevent condensate overflow; when the water level is low, the pump stops, exiting the drainage mode. However, even when the pump stops, condensate remains in the drainage pipe. Due to the high position of the drain outlet, a water level difference exists in the drainage pipe, causing a large amount of condensate to quickly backflow into the storage tank, producing a rinsing sound. With each pump's start and stop, the continuous backflow of condensate and the rinsing sound negatively impact the user experience.

[0056] It is understood that after the water pump of the air conditioner in this embodiment of the application starts, when it is determined that the water pump can exit the drainage mode, the running water pump will not be stopped immediately. Instead, the water pump will be controlled to run at a reduced speed to reduce the backflow speed of the condensate in the drainage pipe, so that the condensate slowly flows back to the water storage device to avoid generating flushing noise.

[0057] It is understood that in this embodiment of the application, after determining that there is no condensate stored in the drainage pipe, the water pump is controlled to stop running. This can avoid unnecessary energy consumption caused by the water pump continuously running at a reduced speed, and at the same time eliminate the noise generated by the water pump running continuously when the water level in the water storage device is low, thereby improving the user experience.

[0058] Here, the first set water level is the overflow warning water level, which is close to the full water level of the water storage device. If the current water level in the water storage device is higher than the first set water level, there is a risk of condensate overflowing. The water pump is controlled to start drainage. In drainage mode, the water pump runs at the first speed.

[0059] For example, determining that the conditions for exiting drainage are met, and then controlling the operating water pump to reduce its speed, includes: determining that the current water level in the water storage device is lower than a second set water level, and then controlling the operating water pump to reduce its speed; and / or, in response to an air conditioner shutdown command, controlling the operating water pump to reduce its speed. Wherein, the first set water level is higher than the second set water level.

[0060] It is understood that the exit drainage conditions set in this application embodiment include the current water level in the water storage device being lower than the second set water level and the air conditioner being turned off. The second set water level is the exit drainage water level. If the current water level in the water storage device is lower than the second set water level, it is determined that there is no risk of condensate overflow in the water storage device in the short term, and the water pump can be controlled to exit the drainage mode. After the air conditioner is turned off, the compressor stops running, and the heat exchanger inside the air conditioner no longer produces condensate. If the water pump is controlled to exit the drainage mode, there is also no risk of condensate overflow in the water storage device.

[0061] Understandably, to avoid frequent start-stop of the water pump, the first set water level is usually higher than the second set water level.

[0062] Understandably, once the conditions for exiting drainage are met, the water pump is no longer used to discharge the condensate in the storage device into the drainage pipe. At this time, the water pump is controlled to reduce its speed, and the driving force of the water pump reduces the backflow speed of the condensate in the drainage pipe. The condensate in the drainage pipe changes from a large amount of rapid backflow into the storage device to a slow backflow into the storage device, eliminating the scouring noise. In addition, the reduced speed of the water pump also reduces the operating noise of the water pump.

[0063] Specifically, in order to reduce the backflow rate of condensate in the drainage pipe during the pump's deceleration operation, this application provides two deceleration operation modes: a pressure detection mode and a step-by-step deceleration mode. This ensures that when the pump stops operating, no condensate will continue to flow back into the water storage device.

[0064] For example, such as Figure 4 As shown, a pressure detection unit 400 is installed on the drainage pipeline. The pressure detection unit 400 is used to detect the water pressure at the lowest point in the drainage pipeline 300 and control the running water pump to reduce its speed. This includes: acquiring the pressure value detected by the pressure detection unit based on a set time interval; if the pressure value is determined to be greater than a set pressure threshold, then controlling the water pump to run at a second speed within the set time interval. The second speed is less than the first speed.

[0065] For example, if it is determined that there is no stored condensate in the drain pipe, then controlling the water pump to stop operating includes: if it is determined that the pressure value has reached a set pressure threshold, then controlling the water pump to stop operating.

[0066] Understandably, in the pressure detection mode, the pressure detection unit 400 is set in the drain pipe 300 in the descending section, and can detect the water pressure at the lowest point in the drain pipe 300; if the pressure detection unit 400 detects that the current pressure value is greater than the set pressure threshold, it determines that there is still a lot of condensate stored in the drain pipe 300, and controls the water pump to continue running.

[0067] In one application example, the pressure threshold is set to a pressure value close to zero water pressure.

[0068] In one application example, when controlling the water pump to reduce its speed, multiple pump speeds can be set, each corresponding to a pressure value. In this application example, based on the determination that the pressure value detected by the pressure detection unit gradually decreases, the water pump is controlled to switch to the corresponding lower speed.

[0069] In some embodiments, detecting the current water level in the drainage pipe is used instead of detecting the lowest water pressure in the drainage pipe. This method can still control the water pump to slow down until there is no stored condensate in the drainage pipe. Specifically, replacing the pressure detection unit with a level switch, float switch, or other level detection unit can also determine if the current water level has reached the level corresponding to a set pressure threshold, indicating that there is no stored condensate in the drainage pipe, and thus control the water pump to stop running.

[0070] For example, controlling the operating water pump to reduce its speed includes: controlling the water pump to operate in a progressively decreasing speed mode. In the progressively decreasing speed mode, the water pump's rotational speed includes multiple set rotational speeds, each corresponding to a specific operating time of the water pump in the progressively decreasing speed mode. Operating the water pump in the progressively decreasing speed mode includes: controlling the water pump to operate at a third rotational speed; if it is determined that the water pump has operated at the current set rotational speed for the corresponding operating time, then controlling the water pump's rotational speed to decrease to the next set rotational speed; the third rotational speed is the maximum set rotational speed in the progressively decreasing speed mode, and the third rotational speed is less than the first rotational speed.

[0071] For example, if it is determined that there is no stored condensate in the drain pipe, then controlling the water pump to stop operating includes: if it is determined that the water pump has been operating in a gradually decreasing speed mode for a first duration, then controlling the water pump to stop operating.

[0072] Understandably, in the step-down mode, the air conditioner does not detect the amount of water in the drain pipe, but instead controls the water pump to run in the step-down mode for a sufficiently long initial duration to ensure that there is no condensate stored in the drain pipe.

[0073] Understandably, in the progressive speed reduction mode, multiple progressively decreasing set speeds are configured, such as a third, fourth, and fifth speed, where the third speed is greater than the fourth, and the fourth speed is greater than the fifth. After confirming that the drainage exit conditions are met, the pump speed is reduced from the first speed to the third speed. After the pump operates at the third speed for the first set operating time, the pump speed is switched to the fourth speed. After the pump operates at the fourth speed for the second set operating time, the pump speed is switched to the fifth speed. After the pump operates at the fifth speed for the third set operating time, the pump stops. The sum of the first, second, and third set operating times constitutes the first duration.

[0074] Understandably, when a water pump operates in a progressively slower speed mode, as the operating time increases, the amount of water stored in the drainage pipe gradually decreases, and the pump speed also decreases accordingly. This reduces the pump's operating energy consumption and the noise generated by the pump operating in the progressively slower speed mode.

[0075] It should be noted that this application does not specifically limit the number of set speeds, speed values, and corresponding running times in the step-down speed mode. Furthermore, based on the different number of set speeds, speed values, and corresponding running times, the effect of controlling the condensate in the drainage pipe to slowly flow back to the water storage device can be achieved in the embodiments of this application.

[0076] In one application example of this application, a control method for an air conditioner is provided, such as... Figure 5 As shown, the method includes:

[0077] Step 501: Control the air conditioner to operate in cooling mode or dehumidification mode.

[0078] Step 502: Obtain the current water level in the water storage device.

[0079] Step 503: Determine whether the current water level in the water storage device is higher than the second set water level. If yes, proceed to step 504; otherwise, proceed to step 502.

[0080] Here, the second set water level is the overflow warning water level.

[0081] Step 504: Control the water pump to start.

[0082] Here, after the water pump starts, it enters the drainage mode and runs at the first speed.

[0083] Step 505: Determine whether the air conditioner has received a shutdown command. If yes, proceed to step 507; otherwise, proceed to step 506.

[0084] Here, if the air conditioner receives a shutdown command, it is determined that no more condensate will be produced inside the air conditioner, and the water pump will exit the drainage mode.

[0085] Step 506: Determine whether the current water level in the water storage device is lower than the first set water level. If yes, proceed to step 507; otherwise, proceed to step 504.

[0086] Here, if the current water level in the water storage device is lower than the first set water level, it is determined that there is no need to continue to discharge the condensate in the water storage device into the drainage pipe, and the water pump exits the drainage mode.

[0087] Step 507: Control the water pump to run at the second speed to reach the set time interval.

[0088] Here, the second speed is less than the first speed, specifically: the second speed is obtained by reducing the first speed by a fixed speed value.

[0089] Step 508: Obtain the pressure value detected by the pressure detection unit.

[0090] Here, the pressure detection unit is located at the lowest point in the drainage pipe.

[0091] Step 509: Determine whether the pressure value is greater than the set pressure threshold. If yes, proceed to step 507; otherwise, proceed to step 510.

[0092] Here, the pressure threshold is set to a pressure value close to zero water pressure. When the current pressure value at the lowest point of the drain pipe drops to the set pressure threshold, it is determined that there is no condensate stored in the drain pipe.

[0093] Step 510: Control the water pump to stop running.

[0094] In one application example of this application, a control method for an air conditioner is provided, such as... Figure 6 As shown, the method includes:

[0095] Step 601: Control the air conditioner to operate in cooling mode or dehumidification mode.

[0096] Step 602: Obtain the current water level in the water storage device.

[0097] Step 603: Determine whether the current water level in the water storage device is higher than the second set water level. If yes, proceed to step 604; otherwise, proceed to step 602.

[0098] Here, the second set water level is the overflow warning water level.

[0099] Step 604: Control the water pump to start.

[0100] Here, after the water pump starts, it enters the drainage mode and runs at the first speed.

[0101] Step 605: Determine whether the air conditioner has received a shutdown command. If yes, proceed to step 607; otherwise, proceed to step 606.

[0102] Here, if the air conditioner receives a shutdown command, it is determined that no more condensate will be produced inside the air conditioner, and the water pump will exit the drainage mode.

[0103] Step 606: Determine whether the current water level in the water storage device is lower than the first set water level. If yes, proceed to step 607; otherwise, proceed to step 604.

[0104] Here, if the current water level in the water storage device is lower than the first set water level, it is determined that there is no need to continue to discharge the condensate in the water storage device into the drainage pipe, and the water pump exits the drainage mode.

[0105] Step 607: After the set preparation time T1 is reached, control the water pump to run at the third speed.

[0106] Here, the preparation time T1 is set as the reserved time for controlling the water pump to enter the step-down speed mode. After the first set time T1 is reached, the water pump will run in the step-down speed mode.

[0107] Here, the third speed is set to 50% of the first speed.

[0108] Step 608: After the first set running time T2 is reached, control the water pump to run at the fourth speed.

[0109] Here, after the water pump operates at the third speed for the first set running time T2, the speed is reduced to the fourth speed.

[0110] Here, the fourth speed is set to 15% of the first speed.

[0111] Step 609: After the second set running time T3 is reached, control the water pump to run at the fifth speed.

[0112] Here, after the water pump operates at the fourth speed for the second set operating time T3, the speed is reduced to the fifth speed.

[0113] Here, the fifth speed is set to 10% of the first speed.

[0114] Step 610: After the third set running time T4 is reached, control the water pump to stop running.

[0115] Here, after the water pump runs at the fifth speed for the third set running time T4, it is determined that there is no condensate stored in the drainage pipe, and the water pump is controlled to stop running.

[0116] In order to implement the method of the embodiments of this application, the embodiments of this application also provide a control device for an air conditioner, which corresponds to the control method described above, and the steps in the embodiments of the control method described above are also fully applicable to the embodiments of this control device.

[0117] like Figure 7 As shown in the illustration, this application provides a control device for an air conditioner. The air conditioner includes a water storage device, a water pump, and a drainage pipe. The water storage device stores condensate generated during air conditioner operation, and the water pump discharges the condensate from the water storage device into the drainage pipe. The control device includes an acquisition module 701, a first control module 702, and a second control module 703. The acquisition module 701 acquires the current water level in the water storage device when the air conditioner is running in cooling or dehumidification mode. The first control module 702 determines if the current water level in the water storage device is higher than a first set water level, and then controls the water pump to start running at a first speed; and determines if the drainage exit condition is met, and then controls the running water pump to reduce its speed. The second control module 703 determines if there is no stored condensate in the drainage pipe, and then controls the water pump to stop running.

[0118] In some embodiments, the first control module 702 is specifically configured to: determine that the current water level in the water storage device is lower than a second set water level, and then control the running water pump to reduce its speed; and / or, in response to an air conditioner shutdown command, control the running water pump to reduce its speed. Wherein, the first set water level is higher than or equal to the second set water level.

[0119] In some embodiments, a pressure detection unit is provided on the drainage pipe. The pressure detection unit is used to detect the water pressure at the lowest point in the drainage pipe. The acquisition module 701 is also used to: acquire the pressure value detected by the pressure detection unit based on a set time interval.

[0120] The first control module 702 is specifically used to: if the pressure value is determined to be greater than a set pressure threshold, control the water pump to operate at a second speed within a set time interval. The second speed is less than the first speed.

[0121] In some embodiments, the second control module 703 is specifically used to: control the water pump to stop running if it is determined that the pressure value has reached a set pressure threshold.

[0122] In some embodiments, the first control module 703 is specifically used to control the water pump to operate in a progressively decreasing speed mode. In the progressively decreasing speed mode, the water pump's rotational speed includes multiple set rotational speeds, each corresponding to a specific operating time of the water pump in the progressively decreasing speed mode.

[0123] In some embodiments, the first control module 702 is specifically used to: control the water pump to operate at a third speed; if it is determined that the water pump has operated at the current set speed for a corresponding running time, then control the water pump speed to decrease to the next set speed. The third speed is the maximum set speed in the step-down speed mode, and the third speed is less than the first speed.

[0124] In some embodiments, the second control module 703 is specifically configured to: if it is determined that the water pump has been running in a gradually decreasing speed mode for a first duration, then control the water pump to stop running.

The various components in the air conditioner 800 are coupled together via a bus system 805. It can be understood that the bus system 805 is used to implement communication between these components. In addition to a data bus, the bus system 805 also includes a power bus, a control bus, and a status signal bus. However, for clarity, in... Figure 8 The general labeled all buses as Bus System 805.
