[0002] When an air conditioner is running, it reduces the humidity in the air. When high humidity air passes through the heat exchanger of the indoor unit, it will condense into small water droplets, which will be distributed on the heat exchanger fins. If there are a lot of them, they will flow into the machine's water collection pan and then be discharged from the machine through the water pump and drain pipe.
[0003] However, when an air conditioner receives a shutdown command, it usually shuts down immediately. After shutdown, the air conditioner has no further operating control, and the condensate accumulated inside remains in the machine. This condensate, remaining on the heat exchanger fins and drip tray, can cause the internal water quality to deteriorate over time. Mold growth on the drip tray can lead to unpleasant odors, and the machine's components being exposed to high humidity for extended periods can also affect the lifespan of its electrical components.

[0039] Figure 3 This is a schematic diagram of the structure of the electronic device provided by the present invention. Detailed Implementation
[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0041] The following is combined Figures 1-3 This invention describes a control method, apparatus, equipment, medium, and air conditioner for controlling the cooling shutdown of an air conditioner, which solves the defect in the prior art that it cannot automatically clean the water inside the air conditioner when it is about to be turned off, and realizes the automatic cleaning of water inside the air conditioner before the air conditioner is turned off, thus avoiding a significant reduction in the lifespan of the air conditioner.
[0042] The present invention also discloses an air conditioner, including a controller, an outdoor unit, and an indoor unit, wherein the controller is electrically connected to the indoor unit and the outdoor unit respectively, the outdoor unit includes a compressor and an outdoor fan, the indoor unit includes an indoor fan, a condenser and a drip tray, the condenser and the drip tray are connected by an indoor coil, and the controller implements the steps of any of the control methods for stopping the air conditioner's cooling operation when executed.
[0043] like Figure 1 As shown, it is a schematic diagram of the implementation process of an air conditioning cooling shutdown control method provided by an embodiment of the present invention. An air conditioning cooling shutdown control method may include, but is not limited to, steps S100 to S300.
[0044] S100 collects the indoor coil temperature when the air conditioner is running in cooling mode and receives a shutdown command.
[0045] S200, compare the temperature of the inner coil with a preset temperature threshold and obtain the water level value of the water receiving pan of the air conditioner;
[0046] S300, when the temperature of the inner coil is greater than or equal to the temperature threshold, control the operation of the indoor fan of the air conditioner until the real-time collected temperature of the inner coil is less than the temperature threshold and the water level indicator value is less than or equal to the preset water level threshold, then execute the shutdown command to control the air conditioner to shut down.
[0047] It should be noted that the execution subject of the air conditioning cooling shutdown control method in this embodiment of the invention can be a hardware device with data information processing capabilities and / or the necessary software to drive the hardware device to work.
[0048] Optionally, the executing entity may include, but is not limited to, workstations, servers, computers, user terminals, and other intelligent devices. User terminals include, but are not limited to, mobile phones, computers, intelligent voice interaction devices, smart home appliances, and in-vehicle terminals.
[0049] In step S100 of some embodiments, when the air conditioner is operating in cooling mode and a shutdown command is received, the temperature of the indoor coil of the indoor coil is collected.
[0050] Understandably, the first step is to determine the current operating mode of the air conditioner. If the current operating mode is cooling, upon receiving a stop command issued by the user via remote control, voice, or gesture, the temperature sensor located on the indoor coil collects the temperature of the indoor coil. This indoor coil temperature is denoted by Tc. The indoor coil temperature indicates the condensate content of the indoor heat exchanger (indoor condenser). Based on the indoor coil temperature, the amount of condensate accumulated in the indoor heat exchanger can be determined. A higher indoor coil temperature indicates a greater amount of condensate accumulated in the indoor heat exchanger, and vice versa.
[0051] In step S200 of some embodiments, the temperature of the inner coil is compared with a preset temperature threshold, and the water level of the air conditioner's water tray is obtained.
[0052] It is understandable that after completing step S100, which involves collecting the temperature of the indoor coil when the air conditioner is running in cooling mode and a shutdown command is received, the specific execution steps can be as follows: comparing the temperature of the indoor coil with a preset temperature threshold to obtain a temperature comparison result.
[0053] It should be noted that the temperature comparison results include at least the first temperature result and the second temperature result.
[0054] When the inner coil temperature is greater than or equal to the temperature threshold, a first temperature result is obtained; when the inner coil temperature is less than the temperature threshold, a second temperature result is obtained.
[0055] A float switch is used to detect the water level in the receiving tray. The float switch uses a magnetic float on top of the switch to rise or fall with the liquid level, causing a reed switch chip inside the switch's detection tube to activate and send an open (close) signal. The receiving tray has graduations, and the graduation on the scale that the float switch pointer points to indicates the water level.
[0056] In step S300 of some embodiments, when the temperature of the inner coil is greater than or equal to the temperature threshold, the indoor fan of the air conditioner is controlled to operate until the real-time collected temperature of the inner coil is less than the temperature threshold and the water level indicator value is less than or equal to the preset water level threshold, and then the shutdown command is executed to control the air conditioner to shut down.
[0057] It is understandable that after performing step S200, which compares the temperature of the inner coil with the preset temperature threshold and obtains the water level value of the water tray of the air conditioner, the specific execution steps can be as follows: if the temperature comparison result indicates that the temperature of the inner coil is greater than or equal to the temperature threshold, the target speed of the inner fan is determined based on the inner coil temperature and the temperature threshold, and the inner fan is controlled to operate at the target speed.
[0058] Further, the temperature difference between the inner coil and the temperature threshold is calculated to obtain the coil temperature difference.
[0059] The temperature difference of the coil is matched with a preset temperature difference parameter table to determine the rotation speed parameter corresponding to the temperature difference of the coil.
[0060] Obtain the current operating speed of the internal fan;
[0061] The target speed of the internal fan is obtained by calculating and processing the current speed and the speed parameters.
[0062] Let the temperature of the inner coil be Tc, the temperature threshold be Ta, and the temperature difference between the coils be Tb.
[0063] The calculation method for the coil temperature difference is: Tb = Tc - Ta
[0064] The temperature difference parameter table indicates that each coil temperature difference value corresponds to a rotation speed parameter within a certain temperature range.
[0065] For example, when Tb is greater than or equal to T1 degrees Celsius, the corresponding rotational speed parameter is m1.
[0066] When Tb is less than T1 and greater than or equal to T2 degrees Celsius, the corresponding rotational speed parameter is m2.
[0067] When Tb is less than T2, the corresponding rotational speed parameter is m3. Among them, m1 is greater than m2, m2 is greater than m3, and T1 is greater than T2.
[0068] The current operating speed of the indoor fan and the speed parameters are calculated and processed to obtain the target speed of the indoor fan. This is achieved by adding the current speed and the speed parameters together. Controlling the indoor fan to operate at the target speed allows for the rapid blowing of condensate accumulated in the indoor heat exchanger into the drip tray, and the condensate in the drip tray is then discharged from the air conditioner through a water pump and drain pipe.
[0069] When the internal fan is controlled to run at the target speed, the shutdown command is executed to control the air conditioner to stop when the real-time collected temperature of the internal coil is lower than the temperature threshold and the water level indicator value is less than or equal to the preset water level threshold.
[0070] Furthermore, the step of executing the shutdown command to control the air conditioner to shut down can specifically be to execute the shutdown command and sequentially control the air conditioner's compressor to shut down and the air conditioner's outdoor fan to shut down;
[0071] If the duration of the external fan shutdown reaches a preset shutdown duration threshold, the internal fan will be shut down.
[0072] According to the shutdown command, the air conditioner compressor is shut down first, then the outdoor fan is shut down. When the shutdown time of the outdoor fan reaches the preset shutdown time threshold, the indoor fan is shut down. This can prevent condensate from accumulating in the indoor heat exchanger and drip tray again.
[0073] In some embodiments of the present invention, after the step of comparing the inner coil temperature with a preset temperature threshold, the method further includes:
[0074] When the temperature of the inner coil is less than the temperature threshold and the water level indicator value is greater than the water level threshold, the target drainage time is obtained by calculating the water level indicator value, the water level threshold and the preset unit drainage time.
[0075] When the duration of operation of the internal fan reaches the target drainage duration, the shutdown command is executed to control the air conditioner to shut down.
[0076] It is understandable that after comparing the inner coil temperature with the preset temperature threshold, if the inner coil temperature is less than the temperature threshold and the water level indicator value is greater than the water level threshold, the water level indicator value and the water level threshold value are calculated to obtain the water level difference.
[0077] Let the water level be represented by S1, the water level threshold be S2, and the water level difference be S3.
[0078] The method for calculating the water level difference is: S3 = S1 - S2.
[0079] The target drainage time is obtained by calculating the preset unit drainage time and the water level difference.
[0080] Unit drainage time, that is, how much water can be discharged per second.
[0081] Let the unit drainage time be t1 and the target drainage time be t2.
[0082] The target drainage time is calculated as follows: t2 = S3 / t1.
[0083] Once the target drainage time is reached by controlling the internal fan to operate for the required duration, a shutdown command is executed to control the air conditioner to stop.
[0084] In some embodiments of the present invention, if Tc ≥ A℃, the machine operates at high speed for N1s; if A℃ > Tc ≥ B℃, the machine operates at high speed for N2s; if B℃ > Tc ≥ C℃, the machine operates at high speed for N3s; if C℃ > Tc, the machine operates at high speed for N4s. After N4s of high speed operation, if the minimum water level in the receiving pan is simultaneously met, the machine can be shut down; otherwise, it continues to operate in cycles of N4s until the condition is met.
[0085] The coil temperature Tc can be used to determine the amount of residual water in the indoor heat exchanger. The indoor fan can blow out the water and excess cooling capacity, thus solving problems such as mold and odor caused by residual condensate in the air conditioner.
[0086] This invention provides a control method, device, equipment, medium, and air conditioner for controlling the cooling shutdown of an air conditioner. When the air conditioner is operating in cooling mode and receives a shutdown command, the method collects the temperature of the indoor coil; compares the indoor coil temperature with a preset temperature threshold, and obtains the water level value of the air conditioner's drip tray; if the indoor coil temperature is greater than or equal to the temperature threshold, the method controls the operation of the air conditioner's indoor fan until the real-time collected indoor coil temperature is lower than the temperature threshold, and the water level value is less than or equal to the preset water level threshold, at which point the shutdown command is executed to control the air conditioner to shut down. This addresses the deficiency in existing technologies where water accumulation inside the air conditioner cannot be automatically cleaned before shutdown, enabling automatic cleaning of water inside the air conditioner before shutdown and preventing a significant reduction in the air conditioner's lifespan.
