[0040] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Combine the following Figure 1-Figure 3 The present invention describes a control method, device, equipment, medium and air conditioner for air conditioning refrigeration shutdown, which is used to solve the defect in the prior art that it is impossible to automatically clean the accumulated water inside the air conditioner when the air conditioner is about to be shut down, and realize automatic cleaning of the accumulated water in the air conditioner before the air conditioner is shut down, so as to avoid a significant reduction in the life of the air conditioner.

[0042] The present invention also discloses an air conditioner, comprising a controller, an outdoor unit and an indoor unit, wherein the controller is connected to the indoor unit and the outdoor unit respectively through electrical signals, the outdoor unit comprises a compressor and an external fan, the indoor unit comprises: an internal fan, a condenser and a water receiving pan, the condenser and the water receiving pan are connected through an indoor coil, and the controller implements the steps of any one of the air conditioner refrigeration shutdown control methods when executed.

[0043] like Figure 1 As shown, it is a schematic diagram of an implementation flow of a control method for air conditioning refrigeration shutdown provided by an embodiment of the present invention. A control method for air conditioning refrigeration shutdown may include but is not limited to steps S100 to S300.

[0044] S100, when the air conditioner is running in cooling mode and a shutdown command is received, collecting the inner coil temperature of the indoor coil;

[0045] S200, comparing the inner coil temperature with a preset temperature threshold, and obtaining a water level representation value of the water receiving pan of the air conditioner;

[0046] S300, when the inner coil temperature is greater than or equal to the temperature threshold, control the inner fan of the air conditioner to operate until the real-time collected inner coil temperature is less than the temperature threshold, and the water level indication value is less than or equal to the preset water level threshold, execute the shutdown command to control the air conditioner to shut down.

[0047] It should be noted that the execution subject of the control method for air-conditioning refrigeration shutdown according to the embodiment of the present invention may be a hardware device with data information processing capability and / or necessary software required to drive the hardware device to work.

[0048] Optionally, the execution subject may include but is not limited to workstations, servers, computers, user terminals and other intelligent devices. Among them, user terminals include but are not limited to mobile phones, computers, intelligent voice interaction devices, smart home appliances, vehicle-mounted terminals, etc.

[0049] In step S100 of some embodiments, when the air conditioner is running in cooling mode and a shutdown command is received, the inner coil temperature of the indoor coil is collected.

[0050] It is understandable that the current operating mode of the air conditioner is first determined. When the current operating mode is the cooling mode, when a shutdown command is received from the user through a remote control, voice, gesture, etc., the temperature sensor provided on the indoor coil is used to collect the inner coil temperature of the indoor coil. Let the inner coil temperature be represented by Tc. The inner coil temperature indicates the condensed water content of the indoor heat exchanger (indoor condenser). According to the inner coil temperature, the condensed water content accumulated in the indoor heat exchanger can be determined. The higher the inner coil temperature, the more condensed water content is accumulated in the indoor heat exchanger, and the lower the inner coil temperature, the lower the condensed water content is accumulated in the indoor heat exchanger.

[0051] In step S200 of some embodiments, the inner coil temperature is compared with a preset temperature threshold, and a water level representation value of the water receiving pan of the air conditioner is obtained.

[0052] It can be understood that after executing step S100, when the air conditioner is running in cooling mode and a shutdown command is received, after collecting the inner coil temperature of the indoor coil, the specific execution steps may be: comparing the inner coil temperature with a preset temperature threshold to obtain a temperature comparison result.

[0053] It should be noted that the temperature comparison result at least includes a first temperature result and a second temperature result.

[0054] When the temperature of the inner coil is greater than or equal to the temperature threshold, a first temperature result is obtained, and when the temperature of the inner coil is less than the temperature threshold, a second temperature result is obtained.

[0055] The float switch is used to detect the water level indication value of the water collection tray. The float switch uses the magnetic float on the switch to rise or fall with the liquid level, so that the reed switch chip at the set position in the switch detection tube is actuated and sends a contact opening (closing) conversion signal. The water collection tray is provided with scale lines, and the scale line pointed by the pointer of the float switch is the water level indication value.

[0056] In step S300 of some embodiments, when the inner coil temperature is greater than or equal to the temperature threshold, the inner fan of the air conditioner is controlled to operate until the real-time collected inner coil temperature is less than the temperature threshold and the water level indication value is less than or equal to the preset water level threshold, and the shutdown instruction is executed to control the air conditioner to shut down.

[0057] It can be understood that after executing step S200 to compare the inner coil temperature with the preset temperature threshold and obtain the water level representation value of the water receiving tray of the air conditioner, the specific execution steps may be: when the temperature comparison result is that the inner coil temperature indicated by the first temperature result is greater than or equal to the temperature threshold, based on the inner coil temperature and the temperature threshold, determine the target speed of the inner fan, and control the inner fan to operate at the target speed.

[0058] Further, the inner coil temperature and the temperature threshold are calculated to obtain a coil temperature difference;

[0059] Matching the coil temperature difference with a preset temperature difference parameter table to determine a speed parameter corresponding to the coil temperature difference;

[0060] Obtaining the current speed of the internal fan;

[0061] The current rotational speed and the rotational speed parameter are calculated and processed to obtain a target rotational speed of the indoor fan.

[0062] Let the inner coil temperature be Tc, the temperature threshold be Ta, and the coil temperature difference be Tb.

[0063] Then the calculation method of the coil temperature difference is: Tb = Tc-Ta

[0064] The temperature difference parameter table indicates that each temperature difference value of the coil corresponds to a speed parameter in the temperature difference range.

[0065] For example, when Tb is greater than or equal to T1 degrees Celsius, the corresponding speed parameter is m1.

[0066] When Tb is less than T1 and greater than or equal to T2 degrees Celsius, the corresponding speed parameter is m2.

[0067] When Tb is less than T2, its corresponding speed parameter is m3, wherein m1 is greater than m2, m2 is greater than m3, and T1 is greater than T2.

[0068] The current speed of the indoor fan and the speed parameter are calculated and processed to obtain the target speed of the indoor fan. That is, the current speed and the speed parameter are added to obtain the target speed of the indoor fan. The indoor fan is controlled to operate at the target speed, so that the condensed water accumulated in the indoor heat exchanger can be quickly blown into the water receiving pan through the indoor fan, and the condensed water in the water receiving pan can be discharged from the air conditioner through the water pump and the drain pipe.

[0069] When the internal fan is controlled to operate at the target speed, until the real-time collected internal coil temperature is less than the temperature threshold and the water level indication value is less than or equal to the preset water level threshold, the shutdown instruction is executed to control the air conditioner to shut down.

[0070] Furthermore, the step of executing the shutdown instruction to control the air conditioner to shut down may specifically be executing the shutdown instruction to sequentially control the compressor of the air conditioner to shut down and the external fan of the air conditioner to shut down;

[0071] When the shutdown time of the external fan reaches a preset shutdown time threshold, the internal fan is controlled to shut down.

[0072] According to the shutdown command, the air conditioner compressor is first shut down, and then the air conditioner's outdoor fan is shut down. When the shutdown time of the air conditioner's outdoor fan reaches the preset shutdown time threshold, the indoor fan is shut down. This can avoid the accumulation of condensed water in the indoor heat exchanger and the water collection pan again.

[0073] In some embodiments of the present invention, after the step of comparing the temperature of the inner coil with a preset temperature threshold, the method further comprises:

[0074] When the temperature of the inner coil is lower than the temperature threshold and the water level indication value is higher than the water level threshold, the water level indication value, the water level threshold and the preset unit drainage time are calculated to obtain a target drainage time;

[0075] When the duration of the internal fan operation is controlled to reach the target drainage duration, the shutdown instruction is executed to control the air conditioner to shut down.

[0076] It can be understood that after comparing the inner coil temperature with the preset temperature threshold, if the inner coil temperature is lower than the temperature threshold and the water level representation value is higher than the water level threshold, the water level representation value and the water level threshold are calculated to obtain the water level difference.

[0077] Let the water level representation value be S1, the water level threshold be S2, and the water level difference be S3.

[0078] Then the calculation method of the water level difference is: S3 = S1-S2.

[0079] The preset unit drainage time and the water level difference are calculated to obtain the target drainage time.

[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: t2 = S3 / t1.

[0083] When the operating time of the internal fan reaches the target drainage time, the shutdown command is executed to control the air conditioner to shut down.

[0084] In some embodiments of the present invention, if Tc ≥ A℃, the machine runs at high wind speed for N1s, if A℃>Tc ≥ B℃, the machine runs at high wind speed for N2s, if B℃>Tc ≥C℃, the machine runs at high wind speed for N3s, if C℃>Tc. After the machine runs at high wind speed for N4s, it can be shut down if the minimum water level in the water tray is met at the same time, and it continues to run for N4s as a cycle if the minimum water level is not met until the condition is met.

[0085] The residual water in the indoor heat exchanger can be determined based on the coil temperature Tc. The water can be blown out by the internal fan, and the excess cold can be blown out at the same time, thus solving problems such as moldy odor caused by residual condensed water in the air conditioner.

[0086] The present invention provides a control method, device, equipment, medium and air conditioner for air conditioning refrigeration shutdown. When the air conditioner is running in cooling mode and receives a shutdown command, the inner coil temperature of the indoor coil is collected; the inner coil temperature is compared with a preset temperature threshold, and the water level indication value of the water receiving pan of the air conditioner is obtained; when the inner coil temperature is greater than or equal to the temperature threshold, the inner fan of the air conditioner is controlled to operate until the real-time collected inner coil temperature is less than the temperature threshold, and the water level indication value is less than or equal to the preset water level threshold, and the shutdown command is executed to control the air conditioner to shut down. It is used to solve the defect in the prior art that the water accumulated inside the air conditioner cannot be automatically cleaned when the air conditioner is about to shut down, and the water accumulated in the air conditioner is automatically cleaned before the air conditioner is shut down, so as to avoid a significant reduction in the life of the air conditioner.
