Embodiment Construction

[0075] figure 1 and Figure 4 A blower 2 is shown comprising a hollow body 3 and an air aeration system 4 housed at least partially in the hollow body 3 .

[0076] like Figure 1 to Figure 4 As shown, the air agitation system 4 more specifically comprises an air intake area 5, an air output area 6 and a centrifugal propeller 7, which is also called a centrifugal fan, and is arranged in the air intake area 5 and the air output area between zone 6.

[0077] The centrifugal propeller 7 rotates around the axis of rotation A, and as Figure 1 to Figure 4 As shown, a plurality of propeller blades 8 configured to generate air flow are included. Said centrifugal propeller 7 is more particularly configured to suck in air through said air intake area 5, while said air agitation system 4 is configured to deliver the air flow generated by said centrifugal propeller 7 to said air output area 6.

[0078] Advantageously, each propeller blade 8 is curved with respect to a respective rad...

Abstract

A system for moving air (4), comprising: a centrifugal impeller (7) rotating about an axis of rotation (A), the centrifugal impeller (7) comprising a plurality of impeller blades (8) configured to generate an airflow, and a base plate (9) comprising a first plate face (9.1) from which the impeller blades (8) project, and a second plate face (9.2) opposite the first plate face (9.1), and a drive motor (18) configured to rotate the centrifugal impeller (7) about the axis of rotation (A), the base plate (9) comprising a plurality of corrugations (14) which are circular and concentric, the plurality of corrugations comprising at least one concave corrugation (14.1) and at least one convex corrugation (14.2), the base plate (9) having a peripheral portion (12) extending opposite the impeller blades and globally parallel to the axis of rotation (A) of the centrifugal impeller (7), characterised in that the base plate (9) comprises a central portion (11) comprising the plurality of corrugations, the central portion (11) of the base plate (9) extending globally perpendicular to the axis of rotation (A) of the centrifugal impeller (7).

Description

technical field [0001] The present invention relates to an air blowing system, and household appliances including the air blowing system. Background technique [0002] An air blowing system for assembling a household appliance such as a hair dryer includes in a known manner: [0003] - a centrifugal propeller movable in rotation about an axis of rotation, the centrifugal propeller comprising a plurality of propeller blades configured to generate an air flow, and a base plate comprising a first deck and a second deck, the the propeller blades protrude from the first board surface, the second board surface is opposite to the first board surface, and [0004] - a drive motor configured to drive the centrifugal propeller in rotation about the axis of rotation. [0005] When the centrifugal propeller of such an air agitation system is driven in rotation by a drive motor, air is drawn through the air intake area of ​​the air agitation system, and the air flow produced by the cen...
