Detection method and detection device for vehicle air conditioner filter

Abstract

The invention provides a detection method and detection device for vehicle air conditioner filter. The detection method comprises the steps that a wind gear position of the vehicle air conditioner is obtained, and a corresponding standard air volume value is obtained according to the wind gear position; an output air volume value output by the current vehicle air conditioner filter is detected; if the difference between the output air volume value and the standard air volume value is greater than a preset air volume difference, then it is determined that the vehicle air conditioner need to be replaced. The detection method and detection device for the vehicle air conditioner filter solve the problems in the prior art that the vehicle air conditioner is still in use when lose filtering ability, which leads to low air quality in a vehicle passenger chamber, at the same time solve the problem that the vehicle air conditioner filter still has the ability to work but is replaced early, which leads to excessive maintenance and waste. The detection method and detection device can automatically detect whether or not the vehicle air conditioner filter works properly, whether or not the vehicle air conditioner filter needs to be replaced, and users do not need to subjectively judge whether or not the vehicle air conditioner filter needs to be replaced.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a detection method and a detection device for a vehicle air-conditioning filter. Background technique [0002] The air conditioner filter on the car, also known as the air conditioner filter element, is generally arranged inside the air intake of the air conditioner box, and is set at the front end of the blower. This device is equipped with filter paper, which utilizes the characteristics of the filter paper to prevent particles from being ventilated. Effective filtering. The filter paper of the double-effect air conditioner filter is attached with activated carbon particles, which can achieve the effect of absorbing air odor while filtering particulate matter. [0003] Most of the current double-effect air-conditioning filters are determined by the customer according to the guidance of the maintenance manual to determine the specific replacement time of the air-conditioning filters.

Problems solved by technology

[0004] Based on the above problems, the present invention proposes a detection method and detection device for a vehicle air conditioner filter. The present invention solves the problem that the vehicle air conditioner filter has lost its filtering ability in the prior art, but it still continues to be used, resulting in poor air quality in the passenger compartment of the vehicle. It also solves the problem that the vehicle air conditioning filter is still working but is replaced in advance, resulting in excessive maintenance and waste
