[0027] In one embodiment of the present invention, S220 includes:

Since the defrosting effect of the electric heating tape is weak when it is turned on, when the operation time is long, the air conditioner can be controlled to enter the defrost mode for deep ice removal; the method of this embodiment effectively avoids the situation where the air conditioner frequently enters the defrost mode, thereby effectively improving the user experience.

Description of the Drawings

[0055] Figure 1 It is a flowchart of the steps of the control method of the air conditioner according to some embodiments of the present invention. Detailed Embodiments

[0056] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following detailed description of the specific embodiments of the present invention is made with reference to the drawings.

[0057]

First Embodiment

[0058] See Figure 1 , this embodiment provides a control method for an air conditioner. An electric heating belt is provided on the outer machine chassis of the air conditioner, and the control method includes:

[0059] S1**00**: Obtain the outdoor ambient temperature, the temperature of the middle pipe in the condenser, and the temperature of the outlet pipe of the condenser;

[0060] S2**00**: Control whether the air conditioner enters the defrosting mode and the opening and closing of the electric heating belt according to the outdoor ambient temperature, the temperature of the middle pipe in the condenser, and the temperature of the outlet pipe of the condenser.

[0061] Further, in S100, an ambient temperature sensor is provided on the outdoor unit of the air conditioner to obtain the outdoor ambient temperature; a pipe temperature sensor is provided in the middle of the U-shaped pipe of the condenser of the outdoor unit of the air conditioner to obtain the pipe temperature in the condenser; a pipe temperature sensor is provided at the outlet of the bottom U-shaped pipe of the condenser of the outdoor unit of the air conditioner to obtain the temperature of the pipe outlet of the condenser.

[0062] Further, in S200, according to the outdoor ambient temperature, the pipe temperature in the condenser, and the temperature of the pipe outlet of the condenser, it is controlled whether the air conditioner enters the defrosting mode and the on / off of the electric heating belt. It should be noted that when the air conditioner enters the defrosting mode, the air conditioner enters the cooling mode; when the air conditioner is operating in normal heating mode, the refrigerant in the condenser pipe will have its temperature reduced during the process of flowing from the middle pipe of the condenser to the outlet pipe of the condenser. Therefore, when the air conditioner is in heating mode, the temperature of the outlet pipe of the condenser is lower than the temperature of the middle pipe of the condenser; the outlet pipe of the condenser is close to the chassis of the outdoor unit, and it can be considered that the temperature of the outlet pipe of the condenser is close to the temperature of the chassis of the outdoor unit.

[0063] It can be understood that the method of this embodiment controls whether the air conditioner enters the defrosting mode and the on / off of the electric heating belt according to the outdoor ambient temperature, the pipe temperature in the condenser, and the temperature of the pipe outlet of the condenser, and can accurately control the defrosting of the air conditioner according to the actual icing situation of the outdoor unit of the air conditioner, saving energy consumption on the basis of ensuring the defrosting efficiency of the air conditioner.

[0064] Further, S200 includes:

[0065] S210: When the air conditioner is turned off, control the on / off of the electric heating belt according to the outdoor ambient temperature and the temperature of the pipe outlet of the condenser;

[0066] S220: When the air conditioner is turned on, control whether the air conditioner enters the defrosting mode and the on / off of the electric heating belt according to the outdoor ambient temperature, the pipe temperature in the condenser, and the temperature of the pipe outlet of the condenser.

[0067] It can be understood that when the air conditioner is turned off, the on / off of the electric heating belt is controlled according to the outdoor ambient temperature and the temperature of the pipe outlet of the condenser, and when the air conditioner is turned on, it is controlled whether the air conditioner enters the defrosting mode and the on / off of the electric heating belt according to the situation; the method of this embodiment takes into account both the off and on states of the air conditioner, effectively improving the reliability of the air conditioner.

[0068] Further, S210 includes:

[0069] S211: When the air conditioner is turned off, compare the outdoor ambient temperature with the first temperature threshold;

[0070] S212: When the outdoor ambient temperature is greater than the first temperature threshold, control the electric heating belt to turn off;

[0071] S213: When the outdoor ambient temperature is less than or equal to the first temperature threshold, control the electric heating tape to turn on.

[0072] Preferably, the first temperature threshold is -5°C.

[0073] Furthermore, in S212, it shows that the outdoor ambient temperature is relatively high at this time, and it is not easy for the outdoor unit chassis to freeze. At this time, the electric heating tape can be controlled to turn off.

[0074] Furthermore, in S213, it shows that the outdoor ambient temperature is relatively low at this time, and it is easy for the outdoor unit chassis to freeze. At this time, the electric heating tape can be controlled to turn on.

[0075] It can be understood that the method of this embodiment can control the opening and closing of the electric heating tape according to the outdoor ambient temperature when the air conditioner is turned off, effectively ensuring the reliability of the air conditioner operation.

[0076] Furthermore, after S213, it further includes:

[0077] S214: Continuously judge whether the temperature of the condenser outlet pipe is greater than or equal to the second temperature threshold;

[0078] S215: When the judgment is yes, control the electric heating tape to turn off;

[0079] S216: When the judgment is no, control the electric heating tape to turn on.

[0080] Preferably, the second temperature threshold is taken as 0°C.

[0081] In this embodiment, the condenser outlet pipe is close to the outdoor unit chassis, and the temperature of the condenser outlet pipe can be considered to be close to the temperature of the outdoor unit chassis. When the temperature of the condenser outlet pipe is greater than or equal to the second temperature threshold, it indicates that the temperature is relatively high at this time, and the possibility of the outdoor unit chassis freezing is relatively low. Then control the electric heating tape to turn off; when the temperature of the condenser outlet pipe is less than the second temperature threshold, it indicates that the temperature is relatively low at this time, and the possibility of the outdoor unit chassis freezing is relatively high. Then control the electric heating tape to turn on.

[0082] It can be understood that the method of this embodiment can accurately detect the defrosting progress of the outdoor unit chassis and perform defrosting for different situations, thereby improving the safety of the air conditioner.

[0083] Furthermore, S220 includes:

[0084] S221: When the air conditioner is cooling, control the air conditioner not to enter the defrost mode and control the electric heating tape to turn off;

[0085] S222: When the air conditioner is heating, control whether the air conditioner enters the defrost mode and the opening and closing of the electric heating tape according to the outdoor ambient temperature, the temperature of the middle pipe of the condenser, the temperature of the condenser outlet pipe, and the continuous operation time t of the air conditioner.

[0086] In this embodiment, when the air conditioner is cooling, the outdoor unit releases heat at this time, and there is no possibility of the outdoor unit chassis icing, so the electric heating tape is controlled to be turned off; when the air conditioner is heating, according to the outdoor ambient temperature, the temperature of the middle pipe in the condenser, the temperature of the outlet pipe of the condenser, and the continuous operation time t of the air conditioner, it is controlled whether the air conditioner enters the defrosting mode and the opening and closing of the electric heating tape.

[0087] It can be understood that the method of this embodiment performs different control methods according to the operation mode of the air conditioner, effectively improving the operation stability of the air conditioner.

[0088] Further, S222 includes:

[0089] S223: When the continuous operation time t is less than the first time threshold, control the opening and closing of the electric heating tape according to the outdoor ambient temperature, the temperature of the middle pipe in the condenser, and the temperature of the outlet pipe of the condenser;

[0090] S224: When the continuous operation time t is greater than or equal to the first time threshold, control whether the air conditioner enters the defrosting mode and the opening and closing of the electric heating tape according to the outdoor ambient temperature and the temperature of the outlet pipe of the condenser.

[0091] Preferably, the first time threshold is set to 40 minutes.

[0092] In this embodiment, when the continuous operation time t is less than the first time threshold, the operation time is short at this time, and only the opening and closing of the electric heating tape is controlled to defrost; when the continuous operation time t is greater than or equal to the first time threshold, the operation time is long at this time, and not only the opening and closing of the electric heating tape is controlled to defrost, but also the air conditioner is controlled to enter the defrosting mode to defrost.

[0093] It can be understood that when the operation time of the air conditioner is short, only the opening and closing of the electric heating tape is controlled to defrost at this time, curbing the icing process of the outdoor unit chassis and effectively reducing the number of times the air conditioner enters the defrosting mode; while when the operation time of the air conditioner is long, the air conditioner is also controlled to enter the defrosting mode to defrost at this time. Since the defrosting effect of the electric heating tape is weak when it is turned on, when the operation time is long, the air conditioner can be controlled to enter the defrosting mode to perform deep defrosting; the method of this embodiment effectively avoids the situation that the air conditioner frequently enters the defrosting mode, and thus effectively improves the user experience.

[0094] Further, S223 includes:

[0095] S223a: When the temperature of the middle pipe in the condenser is greater than the third temperature threshold, control the electric heating tape to be turned off;

[0096] S223b: When the temperature of the middle pipe in the condenser is less than or equal to the third temperature threshold, calculate and determine the first difference between the outdoor ambient temperature and the temperature of the middle pipe in the condenser, and compare the size of the first difference with the fourth temperature threshold;

[0097] When the first difference is greater than the fourth temperature threshold, control the electric heating tape to turn off;

[0098] When the first difference is less than or equal to the fourth temperature threshold and the temperature of the outlet pipe of the condenser is less than the third temperature threshold, control the electric heating tape to turn on.

[0099] Preferably, the value of the third temperature threshold is 0°C.

[0100] Preferably, the value of the fourth temperature threshold is 6°C.

[0101] In this embodiment, when the temperature of the middle pipe in the condenser decreases, at this time, the middle pipe in the condenser is prone to frosting and the chassis of the outdoor unit is prone to icing. At this time, the first difference between the outdoor ambient temperature and the temperature of the middle pipe in the condenser will decrease. That is, when the first difference is less than or equal to the fourth temperature threshold and the temperature of the outlet pipe of the condenser is low, it means that the chassis of the outdoor unit is iced at this time. Therefore, the electric heating tape needs to be turned on at this time.

[0102] It can be understood that the solution of this embodiment judges the icing condition of the chassis of the outdoor unit according to the first difference between the outdoor ambient temperature and the temperature of the middle pipe in the condenser, and implements corresponding control, effectively improving the defrosting efficiency of the air conditioner.

[0103] Further, S224 includes:

[0104] S224a: Calculate and determine the second difference between the outdoor ambient temperature and the temperature of the outlet pipe of the condenser, and compare the size of the second difference with the fifth temperature threshold;

[0105] When the second difference is less than or equal to the fifth temperature threshold, control the air conditioner to enter the defrosting mode and control the electric heating tape to turn on.

[0106] Preferably, the fifth temperature threshold is 8°C.

[0107] In this embodiment, when the second difference between the outdoor ambient temperature and the temperature of the outlet pipe of the condenser is less than or equal to the fifth temperature threshold, it means that the chassis of the outdoor unit has iced at this time. Since the temperature of the outlet pipe of the condenser is less than the temperature of the middle pipe in the condenser, the fifth temperature threshold should be greater than the fourth temperature threshold; since the outlet of the condenser is close to the chassis of the outdoor unit, the second difference between the outdoor ambient temperature and the temperature of the outlet pipe of the condenser can better represent the icing condition of the chassis of the outdoor unit. When the second difference between the outdoor ambient temperature and the temperature of the outlet pipe of the condenser is less than or equal to the fifth temperature threshold, control the air conditioner to enter the defrosting mode, that is, the air conditioner enters the refrigeration mode, and at the same time control the electric heating tape to turn on.

[0108] Understandably, when the air conditioner runs for a long time, the method of this embodiment performs a thorough defrosting and deicing, effectively ensuring the reliability and safety of the air conditioner operation.

[0109] Further, when the second difference is less than or equal to the fifth temperature threshold, after controlling the air conditioner to enter the defrost mode and controlling the electric heating tape to turn on, it further includes:

[0110] When the time when the defrost mode starts reaches the second time threshold, or when the temperature of the condenser outlet pipe is greater than or equal to the sixth temperature threshold, control the air conditioner to exit the defrost mode and control the electric heating tape to turn off;

[0111] Reset the continuous operation time t, and loop to execute the steps of S222.

[0112] Preferably, the second time threshold is set to 12 minutes.

[0113] Preferably, the sixth temperature threshold is set to 10 °C.

[0114] In this embodiment, when the time when the defrost mode starts reaches the second time threshold, or when the temperature of the condenser outlet pipe is greater than or equal to the sixth temperature threshold, it indicates that the air conditioner has completed deicing at this time. Therefore, the air conditioner can be controlled to exit the defrost mode and the electric heating tape can be controlled to turn off. At the same time, reset the continuous operation time t, and loop to execute the steps of S222.

[0115] Understandably, the solution of this embodiment can be looped according to the actual situation, further improving the execution efficiency of the control method of the present invention and effectively enhancing the user's comfort experience and the reliability of the air conditioner operation.
