When oxygen in the air approaches the metal, electrons in the metal are attracted by electrolyte cations in the environment and the metal is decomposed by oxidation of the missing electrons by oxygen or formation of metal positive ions.

For example, a power conversion circuit is provided inside the outdoor unit casing, the power conversion circuit converts the output voltage of the solar cell panel into a negative voltage, the bottom of one side plate of the outdoor unit casing is connected to the ground (i.e., ground potential) of the power conversion circuit, the top cover of the outdoor unit casing is connected to the negative electrode of the power conversion circuit at a position away from the side plate, and when the power conversion circuit is turned on, the negative voltage is applied to the outdoor unit casing.

Optionally, the method further includes storing the electric energy output by the solar panel in a storage battery, converting an output voltage of the storage battery into the negative voltage, and applying the negative voltage to the outdoor unit casing.
With this alternative embodiment, the electrical energy output by the solar panel can be stored, and a negative voltage can be applied to the outdoor unit casing at night or on a continuous cloudy day to provide all-weather corrosion protection for the outdoor unit casing.
For example, the outdoor unit casing is internally provided with: the first power conversion circuit is used for converting the output voltage of the solar panel into the charging voltage of the storage battery; the storage battery is used for storing the electric energy output by the solar cell panel; and the grounding end of the second power conversion circuit is connected to the bottom position of a side plate on one side of the outdoor unit casing, and the negative electrode of the second power conversion circuit is connected to a position, far away from the side plate, on the top cover of the outdoor unit casing.
Fig. 2 illustrates another alternative embodiment of an air conditioner corrosion prevention method.
In this embodiment, the method further includes: step 11, acquiring the running state of the air conditioner; and step 12, controlling the negative voltage applied to the outdoor unit casing according to the running state of the air conditioner. Optionally, the method comprises: controlling on or off of the negative voltage applied to the outdoor unit casing according to an operation state of the air conditioner. Optionally, the method comprises: the on or off of the negative voltage applied to the outdoor unit casing and the magnitude of the negative voltage are controlled according to the operating state of the air conditioner. By adopting the embodiment, the negative voltage applied to the shell of the outdoor unit is controlled according to the running state of the air conditioner, so that the electric energy consumed by the corrosion prevention of the air conditioner can be saved, and the energy consumption of the air conditioner is reduced.
For example, a control panel is arranged in the outdoor unit shell, the control panel is powered by a solar cell panel, the control panel is connected with an outdoor unit control circuit of an air conditioner through an interface circuit, a controller on the control panel can acquire the running state of the air conditioner through an inquiry mode, and the controller controls the power conversion circuit to be switched on or switched off according to the running state of the air conditioner, or controls the power conversion circuit to output negative voltage.
Optionally, the method further comprises: when the air conditioner is operated in a cooling state or a dehumidifying state, the negative voltage applied to the outdoor unit casing is controlled to a first voltage value. Optionally, the first voltage value is-3 to-12V. With this embodiment, when the air conditioner is operated in a cooling state or a dehumidifying state, the outdoor unit casing is in a humid environment or even in an environment with moisture, and therefore, the method controls the negative voltage applied to the outdoor unit casing to be the first voltage value, so that sufficient negative charge can be provided to the outdoor unit casing, and effective corrosion protection can be performed on the outdoor unit casing.
For example, the controller of the air conditioner acquires that the air conditioner operates in a cooling state or a dehumidifying state through an inquiry mode, and the controller controls the output voltage of the power conversion circuit to be-3V to-12V.
Optionally, the method further comprises: when the air conditioner is operated in a standby state, or a heating state, or a blowing state, the negative voltage applied to the outdoor unit casing is turned off. By adopting the embodiment, because the outdoor unit shell is in a dry state, all the parts are relatively stable, the oxidation resistance is higher, and the anticorrosion 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, or a heating state, or a blowing state, the negative voltage applied to the outdoor unit casing is turned off every fixed time interval. By adopting the embodiment, because the air conditioner runs in a standby state, a heating state or an air supply state, the outdoor unit shell is in a dry state, all the components are relatively stable, the oxidation resistance is high, and the anticorrosion protection function does not need to be started all the time, therefore, the negative voltage applied to the outdoor unit shell is turned off at fixed time intervals, and the electric energy consumed by anticorrosion can be saved.
Optionally, when the air conditioner is operated in a standby state, the negative voltage applied to the outdoor unit casing is turned off every first time interval, the turn-off time is a first turn-off time, the first time interval is 0.5-1 hour, and the first turn-off time is 0.5-2 hours. By adopting the embodiment, the negative voltage is started to operate for 0.5-1 hour, so that the anti-corrosion measures of the air conditioner in the standby state time period can be effectively started, electrons flow to the part needing to be protected of the outdoor unit shell and neutralize cations in time, the outdoor unit shell is protected from being oxidized and rusted, and a good anti-corrosion effect is realized; when the time of starting the negative voltage and running for the first time interval is up, the anti-corrosion measures are finished, the time of the first time interval can reach a better anti-corrosion effect, and the energy consumption of the anti-corrosion measures in a standby state can be saved by turning off the first turn-off time of the negative voltage.
Optionally, when the air conditioner is operated in a heating state, the negative voltage applied to the outdoor unit shell is turned off every second time interval, the turn-off time is a second turn-off time, the second time interval is 10-20 minutes, and the second turn-off time is 2-4 hours. Because the environment of the outdoor unit shell is dry when the air conditioner is in a heating state, the oxidized area of the outdoor unit shell is small, and the speed is low, by adopting the embodiment, the negative voltage is started for running for 10-20 minutes, so that the anti-corrosion measure of the air conditioner in the heating state can be effectively started, electrons flow to the part needing to be protected of the outdoor unit shell and neutralize cations in time, and the outdoor unit shell is protected from being oxidized and rusted; when the time of starting the negative voltage and operating the second time interval is up, the anti-corrosion measures are finished, a good anti-corrosion effect can be achieved, and because the oxidized area of the outdoor unit shell in the heating state is small and the speed is slow, the negative voltage is turned off for 2-4 hours, the energy consumption of the anti-corrosion measures in the heating state can be saved.
Optionally, when the air conditioner is operated in the air supply state, the negative voltage applied to the outdoor unit casing is turned off every third time interval, the turn-off time is a third turn-off time, the third time interval is 5-10 minutes, and the third turn-off time is 2-4 hours. Because the environment of the outdoor unit shell is dry when the air conditioner is in an air supply state, the oxidized area of the outdoor unit shell is small, the speed is low, and by adopting the embodiment, the negative voltage is started to operate for 5-10 minutes, so that the anti-corrosion measure of the air conditioner in the air supply state can be effectively started, electrons flow to the part of the outdoor unit shell to be protected and neutralize cations in time, and the outdoor unit shell is protected from being oxidized and rusted; when the time of starting the negative voltage and running the third time interval is up, the anti-corrosion measures are finished, a good anti-corrosion effect can be achieved, and because the oxidized area of the outdoor unit shell in the air supply state is small and the speed is slow, the negative voltage is turned off for 2-4 hours, the energy consumption of the anti-corrosion measures in the air supply state can be saved.
Optionally, the method further comprises: when the air conditioner is operated in a standby state, or a heating state, or a blowing state, the negative voltage applied to the outdoor unit casing is reduced. By adopting the embodiment, when the air conditioner is in a standby state, a heating state or an air supply state, the environment of the outdoor unit shell is dry, all the components are relatively stable, the oxidation resistance is high, and at the moment, a high negative voltage is not required to provide an anti-corrosion protection function all the time, so that the negative voltage applied to the outdoor unit shell is reduced, and the electric energy consumed by anti-corrosion measures can be saved.
Optionally, the method further comprises: when the air conditioner runs in a standby state, a heating state or an air supply state, the negative voltage applied to the outdoor unit shell is controlled to be a second voltage value, and the second voltage value is 20-50% of the first voltage value. With this embodiment, the electrical energy consumed for implementing the anti-corrosion measures can be saved. For example, when the air conditioner is operated in a cooling state or a dehumidifying state, the negative voltage applied to the outdoor unit casing is controlled to be-5V; 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 casing is controlled to be-2.5V.
Fig. 3 illustrates another alternative embodiment of an air conditioner corrosion prevention method.
In this embodiment, the method further includes: step 21, acquiring a humidity value of an environment where an outdoor unit shell is located; and step 22, controlling the negative voltage applied to the outdoor unit casing according to the humidity value. Optionally, the method comprises: the negative voltage applied to the outdoor unit casing is controlled to be turned on or off according to a humidity value of an environment in which the outdoor unit casing is located. Optionally, the method comprises: the on or off of the negative voltage applied to the outdoor unit casing and the magnitude of the negative voltage are controlled according to the humidity value of the environment in which the outdoor unit casing is located. For areas with high environmental humidity, the operating state of the air conditioner cannot be used as the basis for implementing anti-corrosion measures. With this embodiment, the negative voltage applied to the outdoor unit casing is controlled according to the actual environment in which the outdoor unit casing is located, and the outdoor unit casing can be protected from corrosion in all weather according to the actual environment of the outdoor unit casing.
For example, a control panel is arranged inside the outdoor unit casing, the control panel is powered by a solar cell panel, and a controller on the control panel controls the power conversion circuit to be switched on or switched off according to the humidity value of the environment where the outdoor unit casing is located, or controls the magnitude of negative voltage output by the power conversion circuit.
Alternatively, the humidity value is obtained by a humidity sensor provided inside the outdoor unit casing. By adopting the optional embodiment, the humidity sensor is arranged in the outdoor unit shell, so that the humidity value at the position of the outdoor unit shell can be accurately monitored, the environmental condition of the outdoor unit shell is obtained, and the outdoor unit shell is timely and effectively protected. For example, the humidity sensor is provided on the control board.
Optionally, the method further comprises: when the humidity value of the environment where the outdoor unit shell is located meets a first humidity condition, the negative voltage applied to the outdoor unit shell is controlled 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 casing is located satisfies the condition, the negative voltage applied to the outdoor unit casing is controlled according to the humidity value, and the corrosion prevention treatment can be performed on the outdoor unit casing in time and efficiently. For example, when the humidity value of the environment where the outdoor unit casing is located is 65, the controller controls the output voltage of the power conversion circuit to be-5V, negative voltage of-5V is applied to the outdoor unit casing, electrons flow to the part of the outdoor unit casing needing to be protected and neutralize cations in time, and the outdoor unit casing is protected from being rusted by oxidation.
Optionally, when the humidity value of the environment in which the outdoor unit casing is located satisfies a second humidity condition, the negative voltage applied to the outdoor unit casing is controlled to be the second voltage value. 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 casing is reduced according to the humidity value of the environment in which the outdoor unit casing is placed, and the electric power consumed to implement the anti-corrosion measure can be saved. For example, when the humidity value of the environment where the outdoor unit casing is located is 65, the controller controls the output voltage of the power conversion circuit to be-5V, and applies a negative voltage of-5V to the outdoor unit casing; when the humidity value of the environment where the outdoor unit shell is located is 55, the 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 shell.
Alternatively, the negative voltage applied to the outdoor unit casing is turned off when the humidity value of the environment in which the outdoor unit casing is located satisfies a third humidity condition. 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 shell is positioned is lower, the negative voltage applied to the outdoor unit shell 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 casing is located is less than 50, the controller controls the output voltage of the power conversion circuit to be turned off, and the negative voltage applied to the outdoor unit casing is turned off.
Alternatively, when the humidity value of the environment in which the outdoor unit casing is located satisfies a fourth humidity condition, the negative voltage applied to the outdoor unit casing 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. With this embodiment, when the humidity value of the environment in which the outdoor unit casing is located satisfies the condition, it is indicated that the outdoor unit casing is in a higher humidity environment, the negative voltage applied to the outdoor unit casing is increased, the negative charge flowing on the surface of the outdoor unit casing is increased, and the anticorrosion treatment of the outdoor unit casing is performed more effectively. For example, when the outdoor unit casing is in the environment with a humidity value of 65, the controller controls the negative voltage applied to the outdoor unit casing to be-5V; when the humidity value of the environment where the outdoor unit casing is located is 75, the controller controls the negative voltage applied to the outdoor unit casing to be-7.5V.
Fig. 4 illustrates another alternative embodiment of an air conditioner corrosion prevention method.
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 shell is located; and step 32, controlling the negative voltage applied to the outdoor unit casing according to the running state of the air conditioner and the humidity value of the environment where the outdoor unit casing is positioned. By adopting the embodiment, the negative voltage applied to the outdoor unit shell can be controlled together according to the running state of the air conditioner and the humidity value of the environment where the outdoor unit shell 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 shell is located is prevented.
For example, a control panel is arranged inside the outdoor unit casing, the control panel is powered by a solar panel, the control panel is connected with an outdoor unit control circuit of the air conditioner through an interface circuit, a controller on the control panel can acquire the running state of the air conditioner through an inquiry mode, the controller acquires the humidity value of the environment where the outdoor unit casing is located through a humidity sensor, and the controller controls the power conversion circuit to be turned on or off or controls the power conversion circuit to output negative voltage according to the running state of the air conditioner and the humidity value of the environment where the outdoor unit casing is located.
Alternatively, when the humidity value of the environment in which the outdoor unit casing is located does not satisfy the negative voltage opening condition, the negative voltage applied to the outdoor unit casing is controlled according to the operation state of the air conditioner. With this embodiment, metal oxidation occurs even in a long-term operation in an environment with a low humidity value, and therefore, the negative voltage applied to the outdoor unit casing is controlled according to the operating state of the air conditioner, so that reliable implementation of the anti-corrosion measures can be achieved, and the occurrence of a situation in which the anti-corrosion measures are not timely is avoided. For example, when the outdoor unit casing is operated in a cooling or dehumidifying state in which the humidity value of the environment is 45, the negative voltage applied to the outdoor unit casing is controlled according to the operation state of the air conditioner.
Alternatively, when the operation state of the air conditioner does not satisfy the negative voltage opening condition, the negative voltage applied to the outdoor unit casing is controlled according to a humidity value of an environment in which the outdoor unit casing 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 shell 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 casing is controlled according to the humidity value of the environment in which the outdoor unit casing is located.
Alternatively, when both the operating state of the air conditioner and the humidity value of the environment in which the outdoor unit casing is located satisfy the negative voltage on condition, the negative voltage applied to the outdoor unit casing is controlled in accordance with the humidity value of the environment in which the outdoor unit casing is located in such a manner that the humidity value of the environment in which the outdoor unit casing is located takes precedence.
By adopting the embodiment, the humidity value of the environment where the outdoor unit shell is positioned can more directly reflect whether the outdoor unit shell is oxidized, and the corrosion prevention of the outdoor unit shell can be more effectively realized by adopting the mode that the humidity value of the environment where the outdoor unit shell is positioned is prior.
Alternatively, the method for controlling the negative voltage applied to the outdoor unit casing according to the operation state of the air conditioner uses the same embodiment as the embodiment shown in fig. 2 and its alternative embodiment.
Alternatively, the method of controlling the negative voltage applied to the outdoor unit casing according to the humidity value of the environment where the outdoor unit casing is located may be implemented in the same manner as the embodiment shown in fig. 3 and its alternative embodiment.

In this embodiment, the method further includes: step 41, acquiring electrode potential information of an outdoor unit shell; and step 42, controlling the negative voltage applied to the outdoor unit shell according to the electrode potential information. By adopting the optional embodiment, the current required by corrosion prevention is calculated by detecting the electrode potential of the outdoor unit shell, so that the corrosion prevention protection effect can be accurately realized, excessive current is prevented from being provided, and the hydrogen embrittlement phenomenon is prevented from occurring.
For example, a control panel is arranged in the air conditioner shell, the control panel is powered by a solar panel, a lead wire is led from the control panel and is connected to the air conditioner shell, a sensor is attached to the lead wire and is used for detecting the electrode potential of the air conditioner shell in real time, the electrode potential information of the outdoor unit shell is transmitted to the control panel, the controller calculates the required current magnitude, and then the negative voltage applied to the outdoor unit shell is controlled.
