Title:
BLOWER DEVICE AND AIR CONDITIONING DEVICE HAVING SAME MOUNTED THEREIN
Document Type and Number:
WIPO Patent Application WO/2019/116810
Kind Code:
A1
Abstract:
This blower device has: a housing having formed therein an intake air passage which communicates with an air intake opening, and also having formed therein a discharge air passage which communicates with an air discharge opening; a first partition plate for dividing the inside of the housing into the intake air passage and the discharge air passage; a bell-mouth mounted at the peripheral edge of an opening formed in the first partition plate; and an impeller mounted to the first partition plate with the bell-mouth located therebetween and provided with a rotating shaft extending in a direction intersecting the first partition plate. The impeller takes in air from the air intake opening into the intake air passage and discharges the air from the air discharge opening through the discharge air passage. The intake air passage conducts air from the air intake opening along the first partition plate to the opening, and has an air passage wall at a position located at a distance along the first partition plate from the air intake opening beyond the center of the opening. The distance from the rotating shaft of the impeller to the air passage wall is less than the distance from the rotating shaft of the impeller to the end of the bell-mouth, which is located near the air intake opening, and the inflow of air through the air intake opening into the impeller from the side far from the air passage wall is obstructed.
