Example Embodiment

[0032] Hereinafter, reference will be made in detail to various embodiments of the present invention, examples of which are shown in the drawings and described below. Although the present invention will be described in conjunction with exemplary embodiments, it should be understood that this specification is not intended to limit the present invention to those exemplary embodiments. On the contrary, the present invention is intended to cover not only these exemplary embodiments, but also various alternatives, modifications, equivalents, and other specific implementations included in the spirit and scope of the present invention defined by the appended claims. Program.

[0033] When the flow of air in the car is unstable, such as when the vehicle is driving while the windows are open, the air flow around the dust sensor used to measure the dust concentration in the car becomes uneven, so the air flowing into the dust sensor also flows at an uneven flow .

[0034] When the flow rat...

Abstract

The application relates to a dust sensor having a flow control function. A dust sensor apparatus having a flow rate control function for securing reliability of measurement of the dust sensor by constantly maintaining flow rate of the air flowing into the dust sensor for measuring concentration of dust in the internal of a vehicle, may include a blow motor configured for controlling flow rate of the air to be packaged in the dust sensor for measuring concentration of dust in the internal of a vehicle such that flow rate of the air flowing into the dust sensor is maintained constantly.

Description

technical field [0001] The present invention relates to a dust sensor with a flow control function, and more particularly to a dust sensor with a flow control function that ensures the dust sensor by maintaining a constant flow of air flowing into the dust sensor for measuring the dust concentration in a vehicle. Measuring reliability. Background technique [0002] Generally, an automotive air conditioning system is configured to introduce indoor and outdoor air of a vehicle, cool or heat the introduced air, and then blow the cooled or heated air into the vehicle, thereby heating or cooling the interior of the vehicle. The air conditioning system is provided with a filter for filtering foreign matter in the air to be blown into the vehicle. [0003] However, there are limitations in filtering all foreign matter in the air by using a filter. In particular, when the dust concentration in the air outside the vehicle is high, there is concern that a large amount of dust may be...
