WIPO Patent Application WO/2023/182148
Kind Code:
A1
Abstract:
[Problem] The purpose of the present disclosure is to provide a vehicular air conditioning device provided with a particle sensor that enables accurate measurement of particle concentration, through supply of stable air to the particle sensor, without being affected by the amount or speed of air flow blown out from a blower. [Solution] A vehicular air conditioning device 1 according to the present embodiment includes a scroll housing 30 that accommodates an impeller and through which air flows, a motor accommodated in a motor housing, a motor cooling channel 70, and a particle sensor 2. The scroll housing has a tongue portion 34b and a cooling air branch hole 36 that, out of a peripheral wall of the scroll housing, is provided on a wall on a downstream side from the tongue portion. The motor cooling channel communicates with the cooling air branch hole, and has an air outflow opening 71. The particle sensor has a sensor housing 2a, and an air intake opening 2b that takes in air flowing out from the air outflow opening.
