By adopting the embodiment, the negative voltage applied to the outdoor unit bracket is controlled according to the running state of the air conditioner, so that the electric energy consumed by corrosion prevention of the air conditioner can be saved, and the energy consumption of the air conditioner is reduced.

Optionally, the method further comprises: and when the air conditioner operates in a standby state, a heating state or a blowing state, the negative voltage applied to the outdoor unit bracket is turned off. By adopting the embodiment, when the air conditioner runs in a standby state, a heating state or an air supply state, because the outdoor unit bracket is in a dry state, all the components are relatively stable, the oxidation resistance is high, and the anti-corrosion protection function does not need to be started.
For example, when the controller of the air conditioner acquires that the air conditioner operates in a standby state, a heating state or an air supply state through a query mode, the controller turns off the output voltage of the power conversion circuit.
Optionally, the method further comprises: when the air conditioner is operated in a standby state, a heating state, or a blowing state, the negative voltage applied to the outdoor unit bracket is turned off every fixed time interval.

Fig. 3 illustrates another alternative embodiment of a method for protecting a bracket for an outdoor unit of an air conditioner.
In this embodiment, the method further includes: step 21, acquiring a humidity value of an environment where an outdoor unit bracket is located; and step 22, controlling the negative voltage applied to the outdoor unit bracket according to the humidity value. Optionally, the method comprises: and controlling the negative voltage applied to the outdoor unit bracket to be turned on or off according to the humidity value of the environment where the outdoor unit bracket is located. Optionally, the method comprises: and controlling the on or off of the negative voltage applied to the outdoor unit bracket and the magnitude of the negative voltage according to the humidity value of the environment where the outdoor unit bracket is positioned. For areas with high environmental humidity, the operating state of the air conditioner cannot be used as the basis for implementing anti-corrosion measures. By adopting the embodiment, the negative voltage applied to the outdoor unit bracket can be controlled according to the actual environment where the outdoor unit bracket is located, and the outdoor unit bracket can be effectively protected in time according to the actual environment of the outdoor unit bracket.

For example, the humidity sensor is provided on the outdoor unit control panel. With this alternative embodiment, the circuitry of the humidity sensor can be simplified.
Optionally, the humidity value is obtained by a humidity sensor disposed in the indoor environment. An air conditioner generally includes a humidity sensor for measuring humidity of an indoor environment, such as an indoor unit control panel, disposed in the indoor environment, wherein although the humidity sensor is spaced from an outdoor unit bracket, a humidity value obtained by the humidity sensor may approximately reflect the humidity of the outdoor unit bracket, and the humidity value may be converted to be a humidity value of an environment where the outdoor unit bracket is located. By adopting the optional embodiment, the negative voltage applied to the outdoor unit bracket is controlled by the indoor environment humidity value obtained by the existing humidity sensor of the air conditioner, so that the humidity sensor circuit can be simplified, and the outdoor unit bracket can be effectively protected in time.
Optionally, the method further comprises: and when the humidity value of the environment where the outdoor unit bracket is located meets a first humidity condition, controlling the negative voltage applied to the outdoor unit bracket to be the first voltage value. Optionally, the first humidity condition is a humidity value of 60 (relative humidity) or more. Optionally, the first voltage value is 3-12V. With this embodiment, when the humidity value of the environment in which the outdoor unit bracket is located satisfies the condition, the negative voltage applied to the outdoor unit bracket is controlled according to the humidity value, because the environment humidity may still be high when the air conditioner operates in the standby state, the heating state, or the blowing state in southeast asia or coastal areas, and the problem of untimely implementation may occur simply by taking the operation state of the air conditioner as the basis for implementing the anti-corrosion measure, and therefore, with this embodiment, the anti-corrosion treatment can be more effectively performed on the outdoor unit bracket. For example, when the humidity value of the environment where the outdoor unit bracket is located is 65, the air conditioner controller controls the output voltage of the power conversion circuit to be-5V, negative voltage of-5V is applied to the outdoor unit bracket, electrons flow to the part of the outdoor unit bracket to be protected and neutralize cations in time, and the outdoor unit bracket is protected from being oxidized and rusted.

Optionally, the second humidity condition is a humidity value of 50 or more and less than 60. Optionally, the second voltage value is 20% to 50% of the first voltage value. With this embodiment, the negative voltage applied to the outdoor unit bracket is reduced according to the humidity value of the environment in which the outdoor unit bracket is located, and the electric energy consumed for implementing the anti-corrosion measure can be saved. For example, when the humidity value of the environment where the outdoor unit bracket is located is 65, the air conditioner controller controls the output voltage of the power conversion circuit to be-5V, and applies a negative voltage of-5V to the outdoor unit bracket; when the humidity value of the environment where the outdoor unit bracket is located is 55, the air conditioner controller controls the output voltage of the power conversion circuit to be-2.5V, and negative voltage of-2.5V is applied to the outdoor unit bracket.
Optionally, when the humidity value of the environment in which the outdoor unit bracket is located satisfies a third humidity condition, the negative voltage applied to the outdoor unit bracket is turned off. Optionally, the third humidity condition is a humidity value of less than 50. By adopting the embodiment, when the humidity value of the environment where the outdoor unit bracket is located is lower, the negative voltage applied to the outdoor unit bracket is timely turned off, and the electric energy consumed by implementing anti-corrosion measures can be saved. For example, when the humidity value of the environment in which the outdoor unit bracket is located is less than 50, the air conditioner controller controls the output voltage of the power conversion circuit to be turned off, and turns off the negative voltage applied to the outdoor unit bracket.
Optionally, when the humidity value of the environment in which the outdoor unit bracket is located satisfies a fourth humidity condition, the negative voltage applied to the outdoor unit bracket is controlled to be the fourth voltage value. Optionally, the fourth humidity condition is a humidity value of 70 or higher. Optionally, the fourth voltage value is 1.3 to 1.5 times the first voltage value. By adopting the embodiment, when the humidity value of the environment where the outdoor unit bracket is located meets the condition, the outdoor unit bracket is in a higher humidity environment, the negative voltage applied to the outdoor unit bracket is increased, the negative charge flowing through the surface of the outdoor unit bracket is increased, and the anti-corrosion treatment is more effectively carried out on the outdoor unit bracket. For example, when the humidity of the environment in which the outdoor unit bracket is located is 65, the controller of the air conditioner controls the negative voltage applied to the outdoor unit bracket to be-5V; when the humidity value of the environment where the outdoor unit bracket is located is 75, the controller of the air conditioner controls the negative voltage applied to the outdoor unit bracket to be-7.5V.

In this embodiment, the method further includes: step 31, acquiring the running state of the air conditioner and the humidity value of the environment where the outdoor unit bracket is located; and step 32, controlling the negative voltage applied to the outdoor unit bracket according to the running state of the air conditioner and the humidity value of the environment where the outdoor unit bracket is positioned. By adopting the embodiment, the negative voltage applied to the outdoor unit bracket can be controlled together according to the running state of the air conditioner and the humidity value of the environment where the outdoor unit bracket is located, so that the reliable implementation of the anti-corrosion measures is realized, and the situation that the anti-corrosion measures are not timely due to the fact that the anti-corrosion measures are implemented singly according to the running state of the air conditioner or the humidity value of the environment where the outdoor unit bracket is located is prevented.
Alternatively, when the humidity value of the environment where the outdoor unit bracket is located does not satisfy the negative voltage opening condition, the negative voltage applied to the outdoor unit bracket is controlled according to the operation state of the air conditioner. By adopting the embodiment, metal oxidation can still occur in the environment with a lower humidity value after long-time operation, so that the negative voltage applied to the outdoor unit bracket is controlled according to the operation state of the air conditioner, the reliable implementation of anti-corrosion measures can be realized, and the situation that the anti-corrosion measures are untimely can be avoided. For example, when the outdoor unit bracket is located in an environment having a humidity value of 45 and the air conditioner is operated in a cooling or dehumidifying state, the negative voltage applied to the outdoor unit bracket is controlled according to the operation state of the air conditioner.
Optionally, when the operation state of the air conditioner does not satisfy the negative voltage opening condition, the negative voltage applied to the outdoor unit bracket is controlled according to a humidity value of an environment in which the outdoor unit bracket is located. By adopting the embodiment, for southeast Asia or coastal areas, when the air conditioner operates in a standby state, a heating state or an air supply state, the environment humidity is still possibly high, and the problem that the anti-corrosion measures are not implemented timely can occur by simply taking the operating state of the air conditioner as the basis for implementing the anti-corrosion measures, so that the anti-corrosion treatment can be more effectively carried out on the outdoor unit bracket by adopting the embodiment. For example, when the air conditioner is operated in a standby, heating or blowing state, the negative voltage applied to the outdoor unit bracket is controlled according to the humidity value of the environment in which the outdoor unit bracket is located.
Optionally, when the operating state of the air conditioner and the humidity value of the environment in which the outdoor unit bracket is located both satisfy the negative voltage switching condition, the negative voltage applied to the outdoor unit bracket is controlled according to the humidity value of the environment in which the outdoor unit bracket is located in a manner of giving priority to the humidity value of the environment in which the outdoor unit bracket is located.

Optionally, the first unit is further configured to reduce a negative voltage applied to the outdoor unit bracket when the air conditioner is operated in a standby state, a heating state, or a blowing state. With this embodiment, since the outdoor unit bracket 100 is in a dry environment, the components are relatively stable, and the oxidation resistance is high when the air conditioner 40 is in a standby state, a heating state, or a blowing state, the power conversion circuit 30 is not required to always apply a high negative voltage to the outdoor unit bracket 100 to provide the anti-corrosion protection function, and therefore, the first unit 201 controls the power conversion circuit 30 to reduce the negative voltage applied to the outdoor unit bracket 100, so that the power consumed by the anti-corrosion measure can be saved.

With this embodiment, when the humidity value of the environment where the outdoor unit bracket is located meets the condition, the second unit 202 controls the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 according to the humidity value, because the environment humidity may still be large when the air conditioner operates in the standby state, the heating state, or the blowing state in southeast asia or coastal areas, and the problem of untimely implementation may occur simply by taking the operation state of the air conditioner as the basis for implementing the anti-corrosion measure, so with this embodiment, the apparatus can more effectively perform the anti-corrosion treatment on the outdoor unit bracket. For example, when the humidity value of the environment where the outdoor unit bracket is located is 65, the second unit 202 controls the output voltage of the power conversion circuit to be-5V, and applies a negative voltage of-5V to the outdoor unit bracket 100, so that electrons flow to a portion of the outdoor unit bracket 100 to be protected and neutralize cations in time, thereby protecting the outdoor unit bracket 100 from being rusted by oxidation.
Optionally, the second unit 202 is further configured to control the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 to be the second voltage value when the humidity value of the environment in which the outdoor unit bracket is located meets a second humidity condition. Optionally, the second humidity condition is a humidity value of 50 or more and less than 60. Optionally, the second voltage value is 20% to 50% of the first voltage value. With this embodiment, the second unit 202 reduces the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 according to the humidity value of the environment in which the outdoor unit bracket 100 is located, so that the power consumed for implementing the anti-corrosion measure can be saved. For example, when the humidity value of the environment in which the outdoor unit 100 is 65, the second unit 202 controls the output voltage of the power conversion circuit 30 to be-5V, and applies a negative voltage of-5V to the outdoor unit; when the humidity value of the environment where the outdoor unit bracket 100 is located is 55, the second unit 202 controls the output voltage of the power conversion circuit 30 to be-2.5V, and applies a negative voltage of-2.5V to the outdoor unit bracket 100.
Optionally, the second unit 202 is further configured to turn off the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 when the humidity value of the environment in which the outdoor unit bracket 100 is located satisfies a third humidity condition. Optionally, the third humidity condition is a humidity value of less than 50. With this embodiment, when the humidity value of the environment where the outdoor unit bracket is located is low, the second unit 202 turns off the negative voltage applied to the outdoor unit bracket 100 in time, so that the power consumed by implementing the anti-corrosion measure can be saved. For example, when the humidity value of the environment in which the outdoor unit bracket 100 is located is less than 50, the second unit 202 controls the output voltage of the power conversion circuit 30 to be turned off, and turns off the negative voltage applied to the outdoor unit bracket 100.
Optionally, the second unit 202 is further configured to control the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 to be a fourth voltage value when the humidity value of the environment in which the outdoor unit bracket is located meets a fourth humidity condition. Optionally, the fourth humidity condition is a humidity value of 70 or higher. Optionally, the fourth voltage value is 1.3 to 1.5 times the first voltage value. With this embodiment, when the humidity value of the environment in which the outdoor unit bracket 100 is located satisfies the condition, it is indicated that the outdoor unit bracket 100 is located in a higher humidity environment, the negative voltage applied to the outdoor unit bracket 100 is increased, the negative charge flowing through the surface of the outdoor unit bracket 100 is increased, and the corrosion prevention treatment of the outdoor unit bracket 100 is performed more effectively. For example, when the humidity value of the environment in which the outdoor unit bracket 100 is 65, the second unit 202 controls the negative voltage applied to the outdoor unit outdoor; when the humidity value of the environment in which the outdoor unit bracket 100 is located is 75, the second unit 202 controls the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 to be-7.5V.

With this embodiment, the third unit 203 can jointly control the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 according to the operating state of the air conditioner and the humidity value of the environment where the outdoor unit bracket is located, so as to implement reliable anti-corrosion measures, and prevent the situation that the anti-corrosion measures are not timely due to the implementation of the anti-corrosion measures according to the operating state of the air conditioner or the humidity value of the environment where the outdoor unit bracket is located.
Optionally, the third unit 203 is further configured to control the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 according to the operation state of the air conditioner 40 when the humidity value of the environment in which the outdoor unit bracket 100 is located does not satisfy the negative voltage opening condition.

With this embodiment, in the southeast asia or coastal areas, when the air conditioner 40 is in a standby state, a heating state, or an air blowing state, the ambient humidity may still be high, and simply using the air conditioner operating state as the basis for implementing the anti-corrosion measures, the problem of untimely implementation of the anti-corrosion measures may occur, and therefore, with this embodiment, the apparatus 200 may more effectively perform the anti-corrosion treatment on the outdoor unit bracket 100.
Optionally, the third unit 203 is further configured to control the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 according to the humidity value of the environment in which the outdoor unit bracket 100 is located, in a manner that the humidity value of the environment in which the outdoor unit bracket 100 is located is prioritized, when both the operation state of the air conditioner 40 and the humidity value of the environment in which the outdoor unit bracket 100 is located satisfy the negative voltage open condition. By adopting the embodiment, the humidity value of the environment where the outdoor unit bracket is positioned can more directly reflect whether the outdoor unit bracket is oxidized, and the outdoor unit bracket can be more effectively prevented from being corroded by adopting a mode that the humidity value of the environment where the outdoor unit bracket is positioned is prior.
Alternatively, the third unit 203 controls the negative voltage applied to the outdoor unit bracket 100 by the power conversion circuit 30 according to the operation state of the air conditioner, and the same embodiment as the first unit 201 is adopted.
