Embodiment 1

[0035] An anti-odor system for a vehicle air conditioner is used to adjust the temperature of the refrigeration components of the vehicle air conditioner after the vehicle is turned off, so as to prevent it from mildew and odor due to low-temperature condensed water droplets. Such as figure 1 As shown, it specifically includes: a delay conduction module, a vehicle status detection module and a battery status detection module.

[0036] The delay conduction module is connected between the blower and the car battery power supply. Since the delay blower is directly connected to the car power supply through the delay conduction module, it is a constant power supply. Therefore, when the delay conduction module is turned on, the blower supplies power. Not affected by the ignition status of the car. The input terminal of the whole vehicle status detection module is connected to the signal output terminal of each component of the vehicle, which can be acquired by CAN bus, LIN bus or h...

Embodiment 2

[0041] On the basis of Embodiment 1, this embodiment provides a method for preventing peculiar smell of a vehicle-mounted air conditioner, such as image 3 shown.

[0042] An anti-odor method for a vehicle-mounted air conditioner, based on a delay conduction module, a battery state detection module, and a vehicle state detection module, comprising the following steps:

[0043] S10. After detecting that the vehicle is turned off, obtain the voltage information of the battery state detection module, and if the voltage information is greater than the first threshold, perform step S20.

[0044] Specifically, in the case of parking with the engine turned off, the battery status is judged to ensure that the voltage of the cycling battery is sufficient to support the operation of the blower without power loss.

[0045] When it is detected that the power supply voltage is lower than the first threshold when the engine is turned off and parked, the blower with this function is not all...

Embodiment 3

[0050] The difference between this embodiment and Embodiment 2 is that step S10 is optimized in this embodiment.

[0051] In order to avoid the false triggering problem caused by the driver shutting down the vehicle briefly, and also considering the time required for the occupants to get off the vehicle, a large amount of wind will cause discomfort to the user. Also include a delay step before obtaining the car battery voltage in step S10:

[0052] S101. Detect the engine-off state of the car, and start to delay timing if the engine is turned off;

[0053] S102. Continue to execute step S10 after the delay timing is completed.

[0054] The delay time can be between 1 minute and 3 minutes.

Abstract

The invention relates to an odor preventing method and system for a vehicle-mounted air conditioner. On the basis of a delay conduction module, a batter state detection module and a vehicle state detection module, the method comprises the following steps that 10, after a vehicle stalls, voltage information of the battery state detection module is obtained, and if the voltage information is largerthan a first threshold value, the step 20 is executed; 20, a conduction control instruction is sent to the delay conduction module, and a blower is controlled to start through the delay conduction module; 30, the voltage information is monitored, and when the voltage information is smaller than a first threshold value or exceeds a first preset time value after the instruction is sent, a disconnection control instruction is sent to the delay conduction module. The odor preventing method and system for the vehicle-mounted air conditioner have the advantages that an automatic air conditioner control algorithm is redesigned, on the premise that existing comfort is not changed, air conditioner system box odor preventing design is achieved; the battery stain phenomenon is effectively prevented,the practicability is achieved, and energy saving purification is guaranteed.

Description

technical field [0001] The invention relates to the field of vehicle air conditioner control, in particular to a method and system for preventing peculiar smell of a vehicle air conditioner. Background technique [0002] During the use of vehicle-mounted air conditioners, people often turn off the engine immediately after arriving at the destination. Especially in summer, when the air conditioner suddenly stops working, the temperature of the condensing pipe is still very low, and water droplets are easy to condense. Over time, the combination of the residual moisture in the air conditioning system pipes and the dust in the air is very suitable for the reproduction of mold, resulting in a musty smell. [0003] In the prior art, the general preventive method is to turn off the air conditioner a few minutes before parking, and turn on the natural wind later, so as to increase the temperature in the air conditioning duct before parking, reduce the temperature difference with th...
