Description

Technical Field

[0001] This invention relates to the field of air conditioning water pump technology, and more particularly to an air conditioning water pump, control method, device, air conditioner, and medium. Background Technology

[0002] During air conditioner operation, water vapor in the air condenses on the low-temperature evaporator, forming condensate that flows into the drip tray of the indoor unit. If the condensate is not drained from the drip tray in time, it may overflow, potentially damaging the air conditioner. Related technologies primarily use an air conditioner water pump to drain the condensate from the drip tray. However, the installation height of the output pipe also affects drainage efficiency. If the installation height of the output pipe does not match the pump's head, condensate will remain in the pipe and fail to drain properly. Summary of the Invention

[0003] This invention provides an air conditioning water pump, control method, device, air conditioner, and medium that can adapt to different installation heights of the output pipes so that condensate in the drip tray can be discharged in a timely manner.

[0004] In a first aspect, embodiments of the present invention provide a control method for an air conditioning water pump. The air conditioning water pump includes: a housing, a water inlet, a first connection port, a pumping device, an output pipe, and a water level detection device. The water inlet is located at the bottom of the housing, the first connection port is located on a first side of the housing, the pumping device is installed inside the housing and is connected to both the first connection port and the water inlet, the water level detection device is installed on a second side of the housing, a water pump control unit is connected to both the pumping device and the water level detection device, and the output pipe includes a second connection port and a water outlet, the second connection port being connected to the first connection port.

[0005] The control method includes:

[0006] In response to a water level warning signal sent by the water level detection device, the pumping device is controlled to operate at the detection power for a first preset duration;

[0007] In response to the pumping device reaching the first preset duration of operation, the pumping device is controlled to stop.

[0008] When no water level warning signal is received from the water level detection device, the target power is determined based on the detection power, wherein, when the pumping device is operating at the target power, the head height is greater than the outlet height.

[0009] In response to the water level warning signal sent by the water level detection device, the pumping device is controlled to operate at the target power.

[0010] The air conditioning water pump control method according to the first aspect of the present invention has at least the following beneficial effects: When a water level warning signal is received from a water level detection device, indicating that the water level of the condensate in the water receiving pan has reached the water level detection device, that is, there is a risk of the water receiving pan overflowing, at this time, the pumping device can be controlled to run at the detection power for a first preset time to make a preliminary judgment on the height of the outlet. When the pumping device runs for the first preset time, the pumping device is controlled to stop. After the pumping device stops pumping, the water in the water supply pipe will flow back to the water receiving pan. If no water level warning signal is received from the water level detection device, it indicates that the head height of the air conditioning water pump is greater than the height of the outlet when the pumping device is running at the detection power. Then, the target power is determined according to the detection power so that when the pumping device is running at the target power, the head height of the air conditioning water pump is greater than the height of the outlet. This can effectively avoid the situation where the condensate cannot be discharged normally because the installation height of the output pipe is greater than the head height of the air conditioning water pump. In addition, when a water level warning signal is received again from the water level detection device, the pumping device is controlled to operate at the target power, which can promptly drain the condensate in the water receiving pan.

[0011] In the air conditioning water pump control method provided in the embodiments of the present invention, the control method further includes:

[0012] When the pumping device stops and receives the water level warning signal sent by the water level detection device, it adds a power increment to the current detection power to update the detection power, and controls the pumping device to run at the updated detection power for the first preset time.

[0013] In the air conditioning water pump control method provided in this embodiment of the invention, determining the target power based on the detected power includes:

[0014] The detected power is taken as the target power.

[0015] In the air conditioning water pump control method provided in this embodiment of the invention, the step of determining the target power based on the detected power further includes:

[0016] Obtain preset power mapping information, which includes multiple detection power intervals and candidate powers corresponding to the detection power intervals:

[0017] A target power range that matches the detected power is determined from the power mapping information. The target power range represents the detection power range into which the detected power falls.

[0018] The target power is determined based on the candidate power corresponding to the target power range.

[0019] In the air conditioning water pump control method provided in this embodiment of the invention, the step of determining the target power based on the detected power further includes:

[0020] The first head height corresponding to the detection power is determined based on the detection power;

[0021] The reference height is determined based on the first head height;

[0022] The target power is determined based on the reference height.

[0023] In the air conditioning water pump control method provided in the embodiments of the present invention, the control method further includes:

[0024] When the pumping device stops and receives the water level warning signal from the water level detection device, and the detection power is at the maximum output power, the pumping device is controlled to stop and an installation fault signal is issued.

[0025] In the air conditioning water pump control method provided in the embodiments of the present invention, after controlling the pumping device to operate at the target power, the method further includes:

[0026] After the pumping device operates at the target power for a period of time that reaches the second preset duration, and upon receiving the water level warning signal sent by the water level detection device, the pumping device is controlled to stop and a pump failure signal is issued, wherein the second preset duration is longer than the first preset duration.

[0027] Secondly, embodiments of the present invention provide an air conditioning water pump, including...

[0028] case;

[0029] The water inlet is located at the bottom of the casing;

[0030] The first connection port is located on the first side of the housing;

[0031] A water pumping device is installed inside the housing, and the water pumping device is connected to both the first connection port and the water inlet.

[0032] The output pipe includes a water outlet and a second connection port, wherein the first connection port is connected to the second connection port;

[0033] A water level detection device is installed on the second side of the housing, and the bottom end of the water level detection device is at the same level as the bottom end of the first connection port.

[0034] The water pump control unit is connected to the water pumping device and the water level detection device, respectively.

[0035] The water pump control unit is used to execute the control method described in the first aspect.

[0036] The air conditioning water pump provided according to embodiments of the present invention has at least the following beneficial effects: By installing the water level detection device on the second side of the housing, when the air conditioning water pump is installed on the drip tray, if the water level in the drip tray triggers the water level detection device, the water level detection device will send a water level warning signal to the water pump control unit. Compared with the technical solution of external water level detection device, this can effectively reduce problems generated during installation and connection, and improve the reliability of installation and use. Furthermore, the installation height of the air conditioning water pump's output pipe may vary in different usage scenarios. Therefore, when a water level warning signal is received from the water level detection device, it indicates that the condensate level in the drip tray has reached the detection level, meaning there is a risk of overflow. In this case, the pumping device can be controlled to run at the detection power for a first preset time to make a preliminary judgment on the outlet height. After the pumping device has run for the first preset time, it should be stopped. After the pumping device stops pumping, the water in the water supply pipe will flow back to the drip tray. If no water level warning signal is received from the water level detection device, it means that the head of the air conditioning water pump is greater than the outlet height when the pumping device is running at the detection power. Then, the target power can be determined based on the detection power to ensure that the head of the air conditioning water pump is greater than the outlet height when the pumping device is running at the target power. This effectively avoids the situation where the condensate cannot be discharged normally due to the installation height of the output pipe being greater than the head height of the air conditioning water pump. When a water level warning signal is received again from the water level detection device, the pumping device can be controlled to run at the target power to promptly drain the condensate in the drip tray.

[0037] In the air conditioning water pump provided in the embodiment of the present invention, the air conditioning water pump further includes a power control unit and a first switching tube. The control terminal of the power control unit is connected to the control terminal of the first switching tube. The first terminal of the first switching tube is connected to the input power supply. The second terminal of the first switching tube is connected to the power supply terminal of the water pump control unit. The water level detection device is connected to the water level detection terminal of the water pump control unit.

[0038] Thirdly, embodiments of the present invention provide an operation control device, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the control method as described in the first aspect.

[0039] The operation control device provided by the embodiments of the present invention has at least the following beneficial effects: When a water level warning signal is received from the water level detection device, it indicates that the water level of the condensate in the water receiving pan has reached the water level detection device, meaning that there may be a risk of the water receiving pan overflowing. At this time, the pumping device can be controlled to run at the detection power for a first preset time to make a preliminary judgment on the height of the outlet. When the pumping device has run for the first preset time, the pumping device is controlled to stop. After the pumping device stops pumping, the water in the water supply pipe will flow back to the water receiving pan. If no water level warning signal is received from the water level detection device, it indicates that the head height of the air conditioning water pump is greater than the height of the outlet when the pumping device is running at the detection power. Then, the target power is determined according to the detection power so that when the pumping device is running at the target power, the head height of the air conditioning water pump is greater than the height of the outlet. This can effectively avoid the situation where the condensate cannot be discharged normally because the installation height of the output pipe is greater than the head height of the air conditioning water pump. In addition, when a water level warning signal is received again from the water level detection device, the pumping device is controlled to operate at the target power, which can promptly drain the condensate in the water receiving pan.

[0040] Fourthly, embodiments of the present invention provide an air conditioner, including an air conditioning water pump as described in the second aspect embodiment above or an operation control device as described in the third aspect embodiment.

[0041] The air conditioner provided by the embodiments of the present invention has at least the following beneficial effects: When a water level warning signal is received from the water level detection device, it indicates that the water level of the condensate in the drip tray has reached the water level detection device, meaning that there may be a risk of the drip tray overflowing. At this time, the pumping device can be controlled to run at the detection power for a first preset time to make a preliminary judgment on the height of the outlet. When the pumping device has run for the first preset time, the pumping device is controlled to stop. After the pumping device stops pumping, the water in the water supply pipe will flow back to the drip tray. If no water level warning signal is received from the water level detection device, it indicates that the head height of the air conditioning water pump is greater than the height of the outlet when the pumping device is running at the detection power. Then, the target power is determined according to the detection power so that when the pumping device is running at the target power, the head height of the air conditioning water pump is greater than the height of the outlet. This can effectively avoid the situation where the condensate cannot be discharged normally because the installation height of the output pipe is greater than the head height of the air conditioning water pump. In addition, when a water level warning signal is received again from the water level detection device, the pumping device is controlled to operate at the target power, which can promptly drain the condensate in the water receiving pan.

[0042] Fifthly, embodiments of the present invention also provide a computer-readable storage medium storing computer-executable instructions for causing a computer to perform the air conditioning water pump control method described in the first aspect embodiment above.

[0043] The computer-readable storage medium provided in the embodiments of the present invention has at least the following effects: When a water level warning signal is received from a water level detection device, it indicates that the water level of the condensate in the drip tray has reached the water level detection device, meaning there is a risk of the drip tray overflowing. In this case, the pumping device can be controlled to run at the detection power for a first preset time to make a preliminary judgment on the height of the outlet. When the pumping device has run for the first preset time, the pumping device is stopped. After the pumping device stops pumping, the water in the water supply pipe will flow back to the drip tray. If no water level warning signal is received from the water level detection device, it indicates that the head height of the air conditioning water pump is greater than the height of the outlet when the pumping device is running at the detection power. Then, the target power is determined based on the detection power so that when the pumping device is running at the target power, the head height of the air conditioning water pump is greater than the height of the outlet. This can effectively avoid the situation where the condensate cannot be discharged normally because the installation height of the output pipe is greater than the head height of the air conditioning water pump. In addition, when a water level warning signal is received again from the water level detection device, the pumping device is controlled to operate at the target power, which can promptly drain the condensate in the water receiving pan.

[0053] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0054] It is understandable that although functional modules are divided in the device schematic diagram and a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than the module division in the device or the order in the flowchart. The terms "first," "second," etc., in the specification, claims, or the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0055] During air conditioner operation, water vapor in the air condenses on the low-temperature evaporator, forming condensate that flows into the drip tray of the indoor unit. If the condensate is not drained from the drip tray in time, it may overflow, potentially damaging the air conditioner. Related technologies primarily use an air conditioner water pump to drain the condensate from the drip tray. However, when using a water pump, the installation height of the output pipe can affect drainage efficiency. If the installation height of the output pipe does not match the pump's head, condensate will remain in the pipe and fail to drain properly.

[0056] Based on this, the present invention provides an air conditioning water pump, control method, device, air conditioner, and medium. When a water level warning signal is received from a water level detection device, it indicates that the water level of the condensate in the drip tray has reached the water level detection device, meaning there is a risk of overflow. In this case, the pumping device can be controlled to run at the detection power for a first preset time to make a preliminary judgment on the height of the outlet. When the pumping device has run for the first preset time, the pumping device is stopped. After the pumping device stops pumping, the water in the water supply pipe will flow back to the drip tray. If no water level warning signal is received from the water level detection device, it indicates that the head height of the air conditioning water pump is greater than the outlet height when the pumping device is running at the detection power. Then, the target power is determined based on the detection power so that the head height of the air conditioning water pump is greater than the outlet height when the pumping device is running at the target power. This effectively avoids the situation where the condensate cannot be discharged normally due to the installation height of the output pipe being greater than the head height of the air conditioning water pump. In addition, when a water level warning signal is received again from the water level detection device, the pumping device is controlled to operate at the target power, which can promptly drain the condensate in the water receiving pan.

[0057] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0058] Reference Figure 1 , Figure 1 This is a schematic diagram of the structure of the air conditioning water pump provided in an embodiment of the present invention.

[0059] It is understood that the air conditioning water pump includes a housing 100, a water inlet 110, a first connection port 120, a pumping device, an output pipe 200, a water level detection device 300, and a water pump control unit 500. The bottom of the housing 100 has a water inlet 110. When the air conditioning water pump is installed on the water receiving pan 800, the water inlet 110 faces the bottom of the water receiving pan 800 so that water in the water receiving pan 800 can enter the air conditioning water pump. The first side of the housing 100 has a first connection port 120. A pumping device is installed inside the housing 100. The pumping device connects the first connection port 120 and the water inlet 110. When the pumping device is in operation, it can transport the condensate in the water receiving pan 800 from the water inlet 110 to the first connection port 120.

[0060] The output pipe 200 includes an outlet 220 and a second connection port 210, which is connected to the first connection port 120. The output pipe 200 is used to connect the air conditioning water pump to the external environment. When the pumping device is in operation, water in the water receiving tray 800 can be transported from the inlet 110 through the first connection port 120 and the second connection port 210 to the outlet 220, and then the condensate is discharged from the outlet 220. The water level detection device 300 is located on the second side of the housing 100, that is, the water level detection device 300 and the first connection port 120 are located on different sides of the housing 100, which can effectively prevent the water level detection device 300 from being touched when installing the output pipe 200.

[0061] Furthermore, compared to the technical solution of using an external water level detection device 300, this method effectively reduces problems during installation and connection, improving the reliability of installation and use. The water pump control unit 500 is connected to both the water level detection device 300 and the pumping device. The water pump control unit 500 can control the operating status of the pumping device based on the water level detection device 300. For example, under normal circumstances, the pumping device will operate at a lower power or stop operating. When the water pump control unit 500 receives a water level warning signal from the water level detection device 300, it controls the pumping device to increase its operating power or starts operating to remove the condensate from the water receiving pan 800.

[0062] It should be noted that the water level detection device 300 can be installed on the side of the housing 100 away from the first connection port 120. The bottom end of the water level detection device 300 and the bottom end of the first connection port 120 are at the same horizontal plane. The output pipe 200 is generally fixed to the second connection port 210 of the housing 100 by plugging or fastener connection. By setting the bottom end of the water level detection device 300 and the bottom end of the first connection port 120 at the same horizontal plane, when the condensate in the water receiving tray 800 comes into contact with the first connection port 120, the condensate in the water receiving tray 800 will also come into contact with the water level detection device 300. At this time, the water level detection device 300 will send a water level warning signal to the water pump control unit 500. Upon receiving the water level warning signal from the water level detection device 300, the water pump control unit 500 will control the pumping device to increase its operating power or start working to pump the condensate in the water receiving pan 800 away from the water receiving pan 800, which can reduce the corrosive effect of the condensate in the water receiving pan 800 on the first connection port 120 and the second connection port 210.

[0063] It should be noted that the pumping device includes a motor and an impeller. The water pump control unit 500 is connected to the motor, and the motor is connected to the impeller. The water pump control unit 500 drives the motor, and the motor drives the impeller to rotate. As a result, the water in the water receiving tray 800 is transported from the water inlet 110 through the first connection port 120 and the second connection port 210 to the water outlet 220, and then the condensate is discharged from the water outlet 220.

[0064] It should be noted that the air conditioning water pump also includes a control box 400. The control box 400 is located on the side of the housing 100 away from the first connection port 120. A mounting through hole is provided at the lower end of the control box 400. The water level detection device 300 includes a detection unit and a control unit, with the control unit connected to both the detection unit and the water pump control unit 500. When condensate in the drip tray 800 comes into contact with the detection unit, the control unit sends a water level warning signal to the water pump control unit 500. Both the control unit and the water pump control unit 500 are located within the control box 400. The detection unit passes through the mounting through hole and extends downwards, with its bottom end aligned with the bottom end of the first connection port 120. By placing the control box 400 on the outside of the housing 100 and then housing the control unit of the water level detection device 300 and the water pump control unit 500 within it, users can easily inspect and maintain the control unit and the water pump control unit 500.

[0065] It should be noted that the water level detection device 300 can be an ultrasonic sensor. The detection unit includes a receiver and a transmitter. If there is no water between the transmitter and receiver of the ultrasonic sensor, the signal sent by the transmitter cannot be transmitted to the receiver. If there is water between the transmitter and receiver of the ultrasonic sensor, the signal sent by the transmitter is transmitted to the receiver. The control unit can determine whether the condensate in the water receiving pan 800 has reached the water level detection device 300 based on whether the receiver receives the transmitted signal.

[0066] Reference Figure 2 , Figure 2 This is a circuit connection diagram of an air conditioning water pump provided in an embodiment of the present invention.

[0067] It is understood that the air conditioning water pump also includes a power control unit 600 and a first switching transistor Q1. The control terminal of the power control unit 600 is connected to the control terminal of the first switching transistor Q1. The first terminal of the first switching transistor Q1 is connected to the input power supply VCC, and the second terminal of the first switching transistor Q1 is connected to the power supply terminal of the water pump control unit 500. The water level detection device 300 is connected to the water level detection terminal Speed ​​of the water pump control unit 500. The water level warning signal can be a high-level signal. For example, when the condensate in the drip tray 800 comes into contact with the water level detection device 300, the water level detection device 300 continuously sends a high-level signal to the water level detection terminal Speed ​​of the water pump control unit 500 until the condensate in the drip tray 800 no longer comes into contact with the water level detection device 300. That is, after receiving the high-level signal, the water level detection terminal Speed ​​of the water pump control unit 500 can be considered to be in a high water level state, and there is a risk of overflow of the condensate in the drip tray 800.

[0068] It should be noted that the first switching transistor Q1 is a MOSFET. The drain of the first switching transistor Q1 is connected to the power supply terminal of the water pump control unit 500, the source of the first switching transistor Q1 is connected to the input voltage VCC, and the gate of the first switching transistor Q1 is connected to the control terminal of the power supply control unit 600. When the control terminal of the power supply control unit 600 sends a high-level signal to the gate of the first switching transistor Q1, the first switching transistor Q1 is turned on, and the operating current output by the input power supply is input to the water pump control unit 500 through the first switching transistor Q1.

[0069] It should be noted that the power control unit 600 can be the main control chip of the air conditioner water pump. The main control chip can control the power supply of the water pump control unit 500 by controlling the conduction and cutoff of the gate of the first switching transistor Q1. The water pump control unit 500 can also communicate with the main control chip. When the air conditioner water pump malfunctions, the water pump control unit 500 can send a fault signal to the main control chip, and then the main control chip can send alarm information to the outside world.

[0070] Firstly, referring to Figure 3 , Figure 3 This is a flowchart of an air conditioning water pump control method provided in an embodiment of the present invention. This air conditioning water pump control method can be applied to the above-mentioned... Figure 1 and Figure 2 The control method for the air conditioning water pump includes, but is not limited to, the following steps:

[0071] Step S100: In response to the water level warning signal sent by the water level detection device, control the pumping device to run at the detection power for a first preset time.

[0072] Step S200: In response to the pumping device running for a first preset time, control the pumping device to stop.

[0073] Step S300: When no water level warning signal is received from the water level detection device, the target power is determined based on the detection power.

[0074] In step S400, in response to the water level warning signal sent by the water level detection device, the pumping device is controlled to operate at the target power.

[0075] Understandably, when water vapor in the air comes into contact with the low-temperature evaporator, it forms condensate and flows into the drip tray of the indoor unit. As the air conditioner operates for longer periods, the water level in the drip tray increases. If the condensate is not drained in time, it may overflow, potentially damaging the air conditioner. When the condensate level in the drip tray rises to the level detection device (i.e., the condensate comes into contact with the device), the device sends a warning signal to the water pump control unit. In different usage scenarios, the installation height of the air conditioner water pump's output pipe may vary; that is, the outlet height may change depending on the usage environment. If the water pump's head and outlet height do not match, the condensate cannot be drained properly. For example, if the water pump's head is lower than the outlet height, the condensate will remain in the pipe and cannot be drained. To ensure that the condensate in the drip tray can be drained... After receiving a water level warning signal, the pump control unit can first control the pumping device to operate at the detection power for a first preset time to make a preliminary judgment on the outlet height. When the pumping device has been running for the first preset time, it will stop. During the operation of the pumping device, the condensate in the receiving pan will be pumped into the output pipe. If the pumping device is operating at the detection power and the head is greater than the outlet height, the condensate in the receiving pan will flow out from the outlet. After the pumping device stops after the first preset time, since some of the condensate in the receiving pan has been pumped out, even if the condensate in the output pipe flows back into the water level detection device, it will not send a water level warning signal. Therefore, if no water level warning signal is received after the pumping device stops, it can be determined that the outlet height was determined to be greater than the outlet height when the pumping device is operating at the detection power. Then, the target power is determined based on the detection power, where the target power is greater than or equal to the detection power. That is, if the pumping device operates at the target power, it can also pump out the condensate in the receiving pan. Since the operating power of the pumping device to remove condensate from the drip tray has been determined, and condensate is continuously generated during the operation of the air conditioner, when the water level detection device is triggered again, i.e., when the water pump control unit receives the water level warning signal sent by the water level detection device again, it can directly control the pumping device to operate at the target power to promptly remove the water from the drip tray and prevent condensate overflow.

[0076] It should be noted that if the pumping device stops after running at the detection power for the first preset time and the water level detection device does not send a water level warning signal, it means that the condensate in the water receiving pan can be pumped to the outlet. Therefore, the detection power can be directly used as the target power to control the operation of the pumping device.

[0077] Understandably, the target power can be determined based on the power correspondence between the detected power and the preset detected power - target power, so that when the pumping device operates at the target power, it can pump the condensate in the water receiving pan to the outlet. The preset power correspondence between the detected power and the target power can refer to a direct mapping between the two, or a numerical ratio between them. Specifically, in the numerical ratio, the target power can be calculated by multiplying the detected power by the power coefficient and the compensation constant. The power coefficient is greater than 1 to ensure that the target power is greater than the detected power. For example, the power coefficient can be 1.5 and the compensation constant is 10 watts. When the detected power is 200 watts, the target power corresponding to the current detected power can be determined to be 310 watts. Then, when the water pump control unit receives the water level warning signal sent by the water level detection device again, it controls the pumping device to operate with the target power of 310 watts. Alternatively, the target power can be obtained by directly superimposing the detected power with the preset power value, which is equivalent to a power coefficient of 1 and a compensation constant of the preset power value. For example, if the preset power value is 150 watts and the detected power is 200 watts, the target power can be determined to be 350 watts. Then, when the water pump control unit receives the water level warning signal sent by the water level detection device again, it controls the pumping device to operate with the target power of 350 watts.

[0078] In another scenario, the target power is determined through preset power mapping information. This power mapping information includes multiple detection power intervals, each corresponding to a candidate power. The system determines which detection power interval the detected power falls into and uses the candidate power corresponding to that interval as the target power. For example, in the power mapping information, the first detection power interval is 200 watts to 300 watts, and the first candidate power corresponding to it is 400 watts. The second detection power interval is 300 watts to 400 watts, and the second candidate power corresponding to it is 500 watts. The third detection power interval is 400 watts to 500 watts, and the third candidate power corresponding to it is 600 watts. If the detected power is 310 watts, it can be determined that the current detected power falls within the second detection power interval. Therefore, the second candidate power of 500 watts can be used as the target power. When the pump control unit receives another water level warning signal from the water level detection device, it controls the pumping device to operate at the target power of 500 watts.

[0079] Understandably, if no water level warning signal is received from the water level detection device after the pumping device has been running at the detection power for a first preset time and then stopped, it indicates that the first head height is greater than the outlet height when the pumping device is running at the detection power. This means that the outlet height is within the range below the first head height. At this time, a reference height can be obtained using the first head height, and then the target power can be determined based on this reference height. This ensures that when the pumping device is running at the target power, the head height of the air conditioning water pump can reach the reference height, ensuring that the head height is greater than the outlet height, so that the condensate can be discharged smoothly from the outlet.

[0080] It should be noted that in determining the reference height, the reference height can be determined based on the sum of the preset height and the first head height. For example, if the preset height is H and the first head height determined based on the detected power is Ha, then the reference height can be H+Ha. Then, the target power is determined based on the reference height. When the water pump control unit receives the water level warning signal sent by the water level detection device again, it controls the pumping device to operate at the target power, so that the head height of the air conditioning water pump reaches (H+Ha). Alternatively, the first head height can be directly used as the reference height, which is equivalent to a preset height of 0. In this case, the pumping device operates at the target power determined based on the reference height, i.e., the first head height, and the head height of the air conditioning water pump reaches the first head height Ha.

[0081] Understandably, when the water pump control unit controls the pumping device to operate at the target power, it can maintain the pumping device operating at the target power for a third preset time to discharge the condensate in the water receiving pan and increase the time interval of the water level warning signal sent by the water level detection device. The third preset time is longer than the first preset time but shorter than the second preset time.

[0082] Reference Figure 4 , Figure 4 This is a flowchart of a control method for an air conditioning water pump according to another embodiment of the present invention. The control method includes, but is not limited to, the following steps:

[0083] Step S500: After the pumping device stops, a water level warning signal is received from the water level detection device. The current detection power is added with a power increment to update the detection power, and the pumping device is controlled to run at the updated detection power for a first preset time.

[0084] Understandably, if the pump operates at the detection power and the head is less than the outlet height, the condensate in the drip tray cannot be pumped to the outlet, meaning the condensate remains in the output pipe. If the pump stops, the condensate in the output pipe will flow back into the drip tray. Since the condensate wasn't pumped out, this backflow will still trigger the water level detection device, sending a water level warning signal to the pump control unit. Furthermore, the higher the operating power of the pump, the higher the head of the air conditioning water pump. Therefore, when the pump stops and receives the water level warning signal from the detection device, the detection power can be increased to obtain a new detection power, thus increasing the head of the air conditioning water pump. The pump can then be controlled to operate at the new detection power for a first preset time. By continuously adjusting the detection power and judging the outlet height, it can adapt to different outlet heights, improving the versatility of the air conditioning water pump.

[0085] It should be noted that after the pumping device runs at the updated detection power for a first preset time, it will also control the pumping device to stop. If the pumping device stops but still receives a water level warning signal from the water level detection device, it will continue to add power increments to the detection power and then control the pumping device to run at the new detection power for the first preset time until the pumping device has reached its maximum output power or the pump control unit does not receive a water level warning signal from the water level detection device after the pumping device stops.

[0086] It should be noted that after operating at the new detection power for a first preset time, if no water level warning signal is received from the water level detection device after the pumping device stops, the target power is determined using the updated detection power. By adding power increments to the detection power and repeating the test, the power increment is only stopped when the pump control unit does not receive a water level warning signal from the water level detection device after the direct pumping device stops. This ensures that the water in the receiving pan can be pumped out. Furthermore, the higher the operating power of the pumping device, the greater the noise generated during operation. Compared to the technical solution of directly using the maximum operating power, this embodiment of the invention determines the detection power that can pump condensate to the outlet by continuously adding power increments, which can also effectively reduce the noise generated during operation of the pumping device.

[0087] It should be noted that the first preset duration can also be dynamically adjusted according to the magnitude of the detection power.

[0088] Specifically, the power increment added to the detection power can also be a pre-set value. For example, the pumping device is equipped with a first detection power, a second detection power, a third detection power, and a fourth detection power, where the first detection power is less than the second detection power, the second detection power is less than the third detection power, and the third detection power is less than the fourth detection power. The pump control unit first controls the pumping device to run for a first preset time using the first detection power, and then controls the pumping device to stop. If a water level warning signal is received from the water level detection device after the pumping device stops, the second detection power is used to control the pumping device to run for the first preset time, and then the pumping device is controlled to stop. If no water level warning signal is received from the water level detection device after the pumping device stops, the target detection power is determined using the second detection power.

[0089] Specifically, the power increment added to the detected power can be dynamically added as a fixed power increment. For example, initially, the head height corresponding to the detected power is 0.5 meters. After the pumping device operates at this detected power for a first preset time, it is controlled to stop. If, after stopping, the pumping device still receives a water level warning signal from the water level detection device, the power increment is added to the detected power, and the head height corresponding to the updated detected power is 0.7 meters. Then, the pumping device operates at the updated detected power for a first preset time. If, after stopping, the pumping device still receives a water level warning signal from the water level detection device, the power increment is added to the detected power again, and the head height corresponding to the updated detected power is 0.9 meters. That is, after each power increment, the head height corresponding to the updated detected power differs from that corresponding to the detected power before the power increment is added by 0.2 meters.

[0090] Reference Figure 5 , Figure 5This is a flowchart of a control method for an air conditioning water pump according to another embodiment of the present invention. The control method includes, but is not limited to, the following steps:

[0091] Step S600: After the pumping device stops, a water level warning signal is received from the water level detection device, and the detection power is the maximum output power. The pumping device is then controlled to stop and an installation fault signal is issued.

[0092] Understandably, if the pump stops after operating at the detected power for a first preset time and receives a water level warning signal from the water level detection device, it indicates that the condensate in the receiving pan has not been pumped out, meaning the head height is less than the outlet height. In this case, the detected power is incremented to obtain a new detected power, which is then used to control the pump to run for the first preset time. If the detected power has already reached the pump's maximum output power before the power increment is added, it means the pump cannot pump the condensate from the receiving pan to the outlet, meaning the maximum head height is less than the outlet height. This situation may occur because the outlet height of the output pipe is set too high. Therefore, upon receiving a water level warning signal from the water level detection device after the pump stops, and with the detected power at maximum output power, the pump can be stopped and an installation fault signal can be issued. By stopping the pump, the energy consumption of the air conditioning water pump can be reduced, and by issuing an installation fault signal, the user can be alerted to adjust the position of the output pipe in a timely manner.

[0093] It should be noted that issuing an installation fault signal can be done by sending installation fault information to the user's mobile device based on pre-set contact information for the user's mobile device. Installation fault information includes, but is not limited to, SMS reminders, telephone voice reminders, etc.; issuing an installation fault signal can also be done by directly issuing an audible warning signal or an optical prompt signal.

[0094] Reference Figure 6 , Figure 6 This is a flowchart of a control method for an air conditioning water pump according to another embodiment of the present invention. The control method includes, but is not limited to, the following steps:

[0095] In step S700, after the pumping device has been running at the target power for a second preset time, if a water level warning signal is received from the water level detection device, the pumping device is stopped and a pump failure signal is issued.

[0096] Understandably, if the water pump malfunctions while operating at its target power, the condensate in the drip tray cannot be pumped out. If the user is not promptly alerted, condensate overflow may occur, potentially damaging the air conditioner. Furthermore, the water pump generates heat during operation. Prolonged operation can lead to heat buildup and damage, and the higher the operating power of the pump, the more heat it generates. Therefore, after the water pump has been operating at its target power for a second preset time, and a water level warning signal is received from the water level detection device (meaning the condensate level in the drip tray remains above the bottom of the water level detection device after prolonged operation), the water pump can be shut down and a pump malfunction signal can be issued, allowing the user to promptly inspect the air conditioner's water pump. The first preset time is shorter than the second preset time; the second preset time can be determined based on the height of the drip tray or the maximum continuous operating time of the water pump.

[0097] Specifically, the second preset duration can be determined based on the distance between the top of the water receiving pan and the bottom of the water level detection device, as well as the bottom area of ​​the water receiving pan.

[0098] It should be noted that issuing a water pump fault signal can be done by sending water pump fault information to the user's mobile device based on pre-set contact information on the user's mobile device. The water pump fault information includes, but is not limited to, SMS reminders, telephone voice reminders, etc.; issuing a water pump fault signal can also be done by directly issuing an audible warning signal or an optical prompt signal.

[0099] Thirdly, referring to Figure 7 This invention provides an operation control device 700, including a memory 710, a processor 720, and a computer program stored in the memory 710 and executable on the processor 720. The processor 720 executes the program to implement the air conditioning water pump control method of the first aspect embodiment above, for example, executing... Figure 3 Method steps S100 to S400 in the text Figure 4 Method steps S500, Figure 5 Method steps S600 and Figure 6 Method step S700.

[0100] The memory 710, as a non-transitory computer-readable storage medium, can be used to store non-transitory software programs and non-transitory computer-executable programs, such as the air conditioner water pump control method in the above embodiments of the present invention. The processor 720 implements the air conditioner water pump control method in the above embodiments of the present invention by running the non-transitory software program and instructions stored in the memory 710.

[0101] The memory 710 may include a program storage area and a data storage area. The program storage area may store the operating system and application programs required for at least one function; the data storage area may store data required for executing the air conditioning water pump control method described in the above embodiments. Furthermore, the memory 710 may include a high-speed random access memory 710, and may also include non-transitory memory 710, such as at least one disk storage device, flash memory device, or other non-transitory solid-state storage device.

Examples of such networks include, but are not limited to, the Internet, corporate intranets, local area networks, mobile communication networks, and combinations thereof.

[0102] Fourthly, this invention provides an air conditioner that includes an operation control device 700 as described in the third aspect embodiment. When a water level warning signal is received from a water level detection device, indicating that the water level of the condensate in the drip tray has reached the water level detection device, meaning there is a risk of overflow, the pumping device can be controlled to run at the detection power for a first preset time to preliminarily determine the outlet height. When the pumping device has run for the first preset time, the pumping device is stopped. After the pumping device stops pumping, the water in the water supply pipe will flow back to the drip tray. If no water level warning signal is received from the water level detection device, it means that the head height of the air conditioner water pump is greater than the outlet height when the pumping device is running at the detection power. Then, the target power is determined based on the detection power so that the head height of the air conditioner water pump is greater than the outlet height when the pumping device is running at the target power. This effectively avoids the situation where the condensate cannot be discharged normally due to the installation height of the output pipe being greater than the head height of the air conditioner water pump. In addition, when a water level warning signal is received again from the water level detection device, the pumping device is controlled to operate at the target power, which can promptly drain the condensate in the water receiving pan.
