[0066] Embodiment 2
[0067] The present invention provides a control method for a multi-angle defrosting system. Fig.11 The multi-angle defrosting system further comprises a temperature and humidity sensor 11 and a control module 12. The temperature and humidity sensor 11 and the defrosting machine 9 are both signal-connected to the control module 12. The temperature and humidity sensor 11 can detect temperature and humidity.
[0068] The control method of the multi-angle defrosting system of this embodiment can be executed by the control module 12, see Fig.12 The flowchart of the control method of the multi-angle defrosting system shown in FIG. 1 comprises the following steps:
[0069] Step S100: Acquire actual environmental parameter values detected by the temperature and humidity sensor 11, where the actual environmental parameter values include temperature and humidity.
[0070] The above actual environmental parameter values include temperature and humidity.
[0071] Step S200: Determine whether the actual environmental parameter value reaches the set parameter value, and if so, start the defrost machine 9.
[0072] The specific method of starting the defrost machine 9 is to send a start signal to the defrost machine 9, and the defrost machine 9 starts after receiving the start signal.
[0073] The temperature and humidity sensor 11 in the above method obtains the actual environmental parameter value signal of the outside world and transmits it to the control module 12; the control module 12 determines that the start-up condition is met, that is, the actual environmental parameter value meets the set parameter value, and then turns on the defrost machine 9; when the control module 12 determines that the start-up condition is not met and defrosting is not required, that is, the actual environmental parameter value does not meet the set parameter value, the defrost machine 9 is turned off. In this control method, the temperature and humidity sensor 11 is used to detect the temperature and humidity of the environment, and the temperature and humidity sensor 11 is connected to the control module 12 signal to realize automatic control of the work of the defrost machine 9, speed up the defrosting speed, and reduce energy waste.
[0074] In an optional solution of the embodiment of the present invention, the defrost machine 9 has a built-in heating module 13, a temperature sensor 15 and a defrost fan 14. Based on this, starting the defrost machine 9 may also include the following steps: (1) obtaining the actual temperature value detected by the temperature sensor 15; (2) determining whether the actual temperature value reaches the set temperature, and if so, turning off the heating module 13. The temperature sensor 15 can detect the temperature near the heating module 13. When the actual temperature value detected by the temperature sensor 15 is greater than or equal to the set temperature, the heating module 13 stops working to avoid the safety hazard caused by the over-high temperature of the heating module 13. The set temperature is the highest temperature that the heating module 13 can reach.
[0075] By setting a temperature sensor 15, it is detected whether the heating module 13 reaches the set temperature; when the set temperature is reached, the heating module 13 stops working to avoid safety hazards caused by excessive temperature of the heating module 13.
[0076] In an optional solution of the embodiment of the present invention, turning off the heating module 13 may further include the following steps:
[0077] (1) Obtaining the actual temperature value detected by the temperature sensor 15; (2) Adjusting the gear position of the defrost fan 14 according to the actual temperature value.
[0078] The defrost fan 14 can determine whether to adjust the gear according to the actual temperature value detected by the temperature sensor 15, increase or decrease the air volume, which can save energy and reduce waste.
[0079] Based on the structure of the multi-angle defrosting system, the control method of the multi-angle defrosting system is illustrated as follows: when the car starts, the temperature and humidity sensor 11 receives external information. If the temperature is too low and the humidity is too high, the temperature and humidity sensor 11 sends the corresponding information to the control module 12. After judgment, the control module 12 turns on the heating module 13 and turns the defrosting fan 14 to the corresponding gear. When the temperature sensor 15 of the heating module 13 receives information and the heating module 13 reaches the set maximum temperature, the heating module 13 stops heating and heating continuously, and the control module 12 can judge whether the defrosting fan 14 has reached the highest defrosting efficiency by increasing the gear or creating a gear. Thus, the air volume of the instrument panel and the air volume of the first air outlet 3 are controlled.
[0080] The information of the temperature and humidity sensor 11 changes after the defrost machine 9 starts working. When the control module 12 receives the change information, it can control the heating module 13 and the defrost fan 14 to stop working, so as to achieve the effect of automatic defrosting and defogger. At present, most vehicles are equipped with the function of vehicle self-starting, that is, after the vehicle starts, the defrost can be automatically turned on under low temperature or high humidity conditions, and then automatically turned off after the defrosting effect is achieved. No human intervention is required, and there is no risk of visual obstruction, which improves the safe driving performance of the vehicle. In addition, because the present invention adds the first air outlet 3, the defrosting efficiency is improved, and the energy of the vehicle can be saved while working automatically. It will be more beneficial to the current situation where vehicles tend to be pure electric.
