[0042] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention as detailed in the appended claims.

[0043] In the related art, when the outdoor environment is relatively low in winter, if the liquefied water during the defrosting of the outdoor unit after the user used the air conditioner last time is not discharged in time, it will accumulate on the chassis of the outdoor unit and immediately freeze into ice cubes. Or, or in some areas with high humidity in winter, ice cubes will form on the chassis of the outdoor unit after a certain period of time. When the user turns on the machine, the fan blades of the outdoor unit will be damaged by the ice cubes, which will affect the user's use.

[0044] In order to solve the above technical problems, the present invention proposes a control method for an air conditioner. During the ice determination and cleaning procedure, the air conditioner is first operated according to preset rules, and the built-in functional parameters of the air conditioner in this operating state are obtained. The built-in functional parameters are combined to determine whether the chassis of the outdoor unit is frozen when the air conditioner is turned on, and the ice is removed in time. If an abnormality occurs, a fault code is output in time, thereby avoiding damage to the fan blades and not affecting the normal use of the user.

[0045] An exemplary embodiment of the present invention provides a control method for an air conditioner, which includes an ice determination and cleanup procedure and an outdoor fan normal start-up procedure, and can be combined with the outdoor unit chassis of the air conditioner. The control method includes: executing the ice determination and cleanup procedure after corresponding conditions are met, wherein the ice determination and cleanup procedure includes:

[0046] Step S101, controlling the outdoor fan of the air conditioner to operate according to a preset rule;

[0047] Step S102, obtaining the actual power of the outdoor fan motor;

[0048] Step S103: determining whether the chassis of the outdoor unit of the air conditioner is frozen according to the actual power of the motor; if frozen, de-icing the chassis of the outdoor unit.

[0049] In this exemplary embodiment, the air conditioner's outdoor fan is first controlled to operate according to a preset schedule, putting the air conditioner in operation. The outdoor fan's actual motor power is then obtained. Finally, based on the motor's actual power, the outdoor unit chassis is determined to be iced. If so, the chassis is de-iced. During operation according to the preset schedule, the outdoor fan is initially controlled to operate at a low speed (lower than the normal speed required to start the outdoor fan, to prevent damage to the fan blades caused by collisions with foreign objects at higher speeds). By monitoring parameters such as the outdoor fan's motor power, the presence of ice or foreign objects on the chassis is determined, and de-icing is performed promptly to prevent damage to the outdoor unit's blades.

[0050] According to an exemplary embodiment of the present invention, de-icing the chassis includes: activating an electric heater on the chassis of an outdoor unit of an air conditioner to heat the chassis of the outdoor unit of the air conditioner. The chassis of the outdoor unit is detected by detecting parameters such as the motor power of the outdoor fan to determine whether there is ice or foreign matter on the chassis of the outdoor unit. The electric heater on the chassis of the outdoor unit is then used to promptly de-ice the chassis to prevent the fan blades of the outdoor unit from being damaged by ice.

[0051] According to an exemplary embodiment of the present invention, Figure 2 As shown, this embodiment includes all the contents of the above embodiments, except that this embodiment determines whether the chassis of the outdoor unit of the air conditioner is frozen based on the actual power of the motor, including:

[0052] Step S201, obtaining the cycle corresponding to the current speed of the outdoor fan;

[0053] Step S202, determining the number of times a preset condition is satisfied within a working cycle, wherein the preset condition includes: the actual power of the motor is greater than the standard power of the motor when the outdoor fan operates according to a preset rule;

[0054] Step S203 , determining whether the chassis of the outdoor unit of the air conditioner is frozen based on the number of times the actual power of the motor is greater than the standard power of the motor.

[0055] In this exemplary embodiment, when the air conditioner is turned on, the outdoor fan first runs at a low speed. By monitoring parameters such as changes in motor power, the presence of ice or foreign objects on the outdoor unit chassis is determined. The principle is to use the air conditioner's electronic control parameters to determine whether the outdoor fan blades are at risk of hitting foreign objects such as ice or rocks on the chassis. Specifically, under certain conditions, when the outdoor fan speed is constant, its motor power remains constant. However, if the blades hit ice, the operating resistance increases, and the motor power of the outdoor fan increases compared to normal operation. Therefore, by setting a standard motor power and comparing it with the actual motor power, the presence of ice can be determined.

[0056] According to an exemplary embodiment of the present invention, this embodiment includes all of the above embodiments, except that it determines whether the chassis of the outdoor unit of the air conditioner is frozen based on the number of times the actual power of the motor is greater than the standard power of the motor, including:

[0057] If the number of times that the actual power of the motor is greater than the standard power of the motor is equal to the number of blades of the outdoor fan, it is determined that the chassis of the outdoor unit of the air conditioner is frozen;

[0058] If the number of times that the actual power of the motor is greater than the standard power of the motor is less than the number of blades of the outdoor fan, it is determined that the chassis of the outdoor unit of the air conditioner is not frozen.

[0059] In this exemplary embodiment, the outdoor fan has rotated once during a working cycle, during which time the fan blades will collide with foreign objects (including ice cubes). Since ice cubes are fixed objects, each fan blade will collide with them once during the working cycle. Therefore, the number of collisions can be used to determine whether the outdoor unit chassis of the air conditioner has ice. After it is determined that ice has formed, the electric heating on the outdoor unit chassis can be used to promptly remove ice to prevent the outdoor unit fan blades from being damaged by ice cubes. It should be noted that when the ice cubes are small, the fan blades will not collide with the ice cubes. At this time, the ice determination and cleaning procedure is not executed to determine whether the outdoor unit chassis is frozen, and the fan blades will not be damaged by colliding with ice cubes.

[0060] According to an exemplary embodiment of the present invention, this embodiment includes all the contents of the above embodiments, with the difference being that determining whether the chassis of the outdoor unit of the air conditioner is not frozen includes: if the number of times that the actual power of the motor is greater than the standard power of the motor is greater than 0 and is less than the number of wind blades of the outdoor fan, then determining that non-ice foreign matter exists on the chassis of the outdoor unit of the air conditioner; if the number of times that the actual power of the motor is greater than the standard power of the motor is equal to 0, then determining that the chassis of the outdoor unit of the air conditioner is not frozen and the normal startup procedure of the outdoor fan can be executed.

[0061] In this exemplary embodiment, when a foreign object is present, it will be displaced by colliding with the blades. The blades will not collide with every blade of the outdoor fan within a single operating cycle. Therefore, if the number of times the actual motor power exceeds the standard motor power within a single operating cycle is between 0 and the number of blades, it is determined that a foreign object (not ice on the outdoor unit chassis) is present. In this case, a corresponding alarm device can provide an alarm, including light and sound alarms. If no collision occurs, the outdoor fan can be directly started at its normal startup speed.

[0062] According to an exemplary embodiment of the present invention, Figure 3 As shown, this embodiment includes all the contents of the above embodiments, except that the icing determination and cleaning procedure also includes:

[0063] Step S301, after turning on the electric heating, detecting the chassis temperature of the outdoor unit chassis;

[0064] Step S302: When the chassis temperature satisfies the requirement of being continuously higher than the first preset temperature within the preset time, the ice determination and clearing procedure is re-executed.

[0065] In this exemplary embodiment, after the outdoor unit chassis is heated, all or part of the ice has been removed, thereby preventing the fan blades from colliding with it. When the temperature is higher than a first preset temperature (such as 2°C) within a preset time (such as 10S), the judgment of ice formation can be re-performed, and the de-icing judgment process can be accurately implemented. Energy saving is also achieved while preventing the fan blades from being damaged by ice and improving the reliability of the air conditioner.

[0066] According to an exemplary embodiment of the present invention, this embodiment includes all the contents of the above embodiments, except that the control method further includes:

[0067] After the air conditioner is started, the outdoor ambient temperature where the outdoor fan is located is detected;

[0068] When the outdoor ambient temperature is lower than a second preset temperature (such as 2°C), the air conditioner is determined to execute an ice determination and cleaning procedure; when the outdoor ambient temperature is equal to or higher than the second preset temperature, the air conditioner is determined to execute a normal outdoor fan start-up procedure.

[0069] In this exemplary embodiment, since there is no possibility of ice formation when the outdoor temperature is high, the air conditioner startup procedure can be optimized by judging whether to execute the ice determination and cleaning procedure after collecting the outdoor ambient temperature, thereby improving the startup efficiency, being more humane, and improving the user experience.

[0070] The following example uses an outdoor fan with three blades. The air conditioner's outdoor unit chassis is equipped with an electric heater, a chassis temperature sensor, and an ambient temperature sensor. The chassis temperature is Td, the outdoor ambient temperature is Tw, and the motor power is P. After the air conditioner is started, it can monitor relevant parameters such as the outdoor ambient temperature and the outdoor fan motor power in real time.

[0071] After the user turns on the air conditioner, the air conditioner obtains parameters such as the outdoor ambient temperature and the motor power of the outdoor fan. When the outdoor ambient temperature Tw ≥ 2°C, the outdoor fan runs to the target speed according to normal logic, that is, the normal startup procedure of the outdoor fan is executed; when the outdoor ambient temperature Tw < 2°C, the outdoor fan runs at a speed of As / rpm (slow speed so as not to damage the fan blades) and obtains the actual motor power P1. Assuming that the angular velocity of the current fan blade rotation is 2π / Arad / s, there is ice on the chassis of the outdoor unit, and the fan blade hits the ice on the chassis of the outdoor unit, taking 3 fan blades as an example, the arc occupied by each fan blade is 2π / 3, so the time when the nearest end of each fan blade hits the ice is (2π / 3) ÷ (2π / A) = A / 3s / time (It should be noted that: when the number of fan blades is N, the period of the fan blade hitting the ice is A / Ns / time, And when the machine is just turned on, the torque of the motor is large, and when the motor encounters resistance, it will not affect its rotation speed). When the air conditioner detects that the actual power of the motor P1 is greater than the standard power of the motor P, and detects it three times in a row, that is, the outdoor fan rotates one circle, the air conditioner stops and the light on the indoor unit display panel of the air conditioner flashes to remind the user, and the electric heating of the outdoor unit chassis starts. When the chassis temperature sensor detects that the chassis temperature is ≥2℃ for 10 seconds in a row, the air conditioner starts and repeats the above judgment action. When the system does not detect the above motor power abnormality and runs at stable power, the outdoor fan speed rises to normal speed and the display panel stops flashing. When the system still detects that the actual power of the motor P1 is greater than the standard power of the motor P for 1 or 2 times, this judgment means that the fan blade hits a foreign object other than ice, then the air conditioner system stops and outputs the corresponding fault code on the indoor unit display.
