The present invention provides a kind of Defrost method of dehumidifier, and this method is implemented by the controller inside dehumidifier, such as Fig. 1
It is shown comprising following steps：
S11：Obtain the ambient temperature value of dehumidifier local environment.
Mountable on dehumidifier to have temperature inductor, temperature inductor can obtain the temperature of ambient enviroment in real time, and can
The environment temperature sensed is sent to controller.In order to promote the accuracy of detected temperature, multiple temperature can be set
Sensor, or repeatedly measurement in the given time.
S12：Corresponding defrosting strategy is determined according to the ambient temperature value, and the defrosting strategy includes the first current control
The configuration parameter of device, first voltage controller and the second current controller.
Controller determines corresponding defrosting strategy according to environment temperature, specifically, prestored in controller environment temperature with
Defrost tactful mapping relations, after getting ambient temperature value, according to the mapping relations, that is, can determine corresponding defrosting plan
Slightly.The defrosting strategy defines how to implement to control to the first current controller, first voltage controller and the second current controller
System, the specific configuration parameter comprising the first current controller, first voltage controller and the second current controller, the configuration parameter
Including but not limited to working time, output voltage and output electric current.
S13：The first current controller, first voltage controller and the second current controller are controlled under the configuration parameter
Work so that the semiconductor cooling fin that is connected with the first current controller, first voltage controller and with the second current control
The connected radiator fan of device is in corresponding working condition.
Controller will be implemented to control to the first current controller, first voltage controller and the second current controller, make the
One current controller, first voltage controller and the second current controller work under the configuration parameter defined by defrosting strategy,
First current controller, the voltage of first voltage controller or the output of the second current controller or electric current change, so that semiconductor
Cooling fin and radiator fan work under different working condition, for different environment temperatures, preset multiple defrosting strategies,
Each defrosting strategy is used to make semiconductor cooling fin and radiator fan co-ordination, and semiconductor cooling fin had both possessed the function of dehumidifying
Can, and will not frosting.
In one embodiment, when environment temperature is greater than or equal to 10 degree, the defrosting it is tactful to semiconductor cooling fin with
Radiator fan is controlled, and adjusts semiconductor cooling fin and radiator fan adaptively, so that the temperature of semiconductor cooling fin huyashi-chuuka (cold chinese-style noodles)
Degree is maintained at 0-5 degree.The cooling on piece of semiconductor is also equipped with temperature sensor, with real-time detection semiconductor cooling fin huyashi-chuuka (cold chinese-style noodles) and/
Or the temperature in hot face.Specifically, the temperature when cooling fin huyashi-chuuka (cold chinese-style noodles) is less than the value range, the electric current of the first current controller can be reduced
Output reduces the power of semiconductor cooling fin, and radiator fan stops working.When the temperature of cooling fin huyashi-chuuka (cold chinese-style noodles) is greater than the range
Value can increase the electric current output of the first current controller, promote the power of semiconductor cooling fin, and radiator fan opens work,
The temperature of keeping body cooling fin huyashi-chuuka (cold chinese-style noodles) is in 0-5 degree.

Change for mode, and the configuration parameter of first current controller makes the temperature of semiconductor cooling fin huyashi-chuuka (cold chinese-style noodles) be maintained at 4-6
Degree.
Temperature sensor by the temperature of real-time detection semiconductor cooling fin huyashi-chuuka (cold chinese-style noodles), the configuration parameter of the first current controller and
The configuration parameter of second current controller is reference according to the temperature.When cooling fin huyashi-chuuka (cold chinese-style noodles) temperature be less than the value range, can
The electric current output for reducing the first current controller, reduces the power of semiconductor cooling fin.It is somebody's turn to do when the temperature of cooling fin huyashi-chuuka (cold chinese-style noodles) is greater than
Value range can increase the electric current output of the first current controller, promote the power of semiconductor cooling fin.Second current controller
Electric current then iteratively changes, and defrosting strategy includes preset iteration function, and the electric current foundation of the second current controller should be repeatedly
Change for function, the temperature of semiconductor cooling fin huyashi-chuuka (cold chinese-style noodles) is then made to be maintained at 4-6 degree.

Face, under electric current input in the opposite direction, the first face is changed to hot face, and the second face is changed to huyashi-chuuka (cold chinese-style noodles).Therefore, defrosting strategy limits
The output polarity overturning of first voltage controller, so that the electric power polarity of semiconductor cooling fin positive and negative polarities input changes, it is former
The temperature of some huyashi-chuuka (cold chinese-style noodles) increases the white body that can eliminate huyashi-chuuka (cold chinese-style noodles), after frost body to be canceled, restores original semiconductor cooling fin power supply pole
Property, then continue to dehumidify.Since reversing has occurred in voltage, it is unsuitable for working long hours, is otherwise easily damaged device, pole
After sexually revising, the electric current of the first current controller output is gradually increased from zero, so that after polarity upset, semiconductor cooling fin
Power is gradually increased, and prevents mutation from causing device failure.
Further, the defrosting strategy defines after the output polarity of first voltage controller overturns the predetermined time,
The output polarity of first voltage controller is overturn again.
In view of semiconductor cooling fin is easy to lead to device failure because power supply reversing time is too long, then must accurately control
Duration, it is ensured that equipment operates normally.Therefore, the working time of semiconductor cooling fin after polarity upset is limited, in first voltage
After the output polarity overturning predetermined time of controller, the output polarity of first voltage controller is overturn again, is repeated the above process,
So that the power supply signal for being loaded into the cooling on piece of semiconductor is the triangular waveform of rule.
