Personalized air purification device
A personalized air cleaning device having a housing which has at least one air intake region for sucking air into the housing and at least one air blow-out region for blowing the air out of the housing, a cleaned blow-out air stream being directed towards the body, and in particular against the face of a user, the housing of the air cleaning device being of approximately disc-shaped round or oval or polygonal design, and wherein the air intake region and the air outlet region are arranged in the same plane on the circumference of the housing.
1. A personalized air cleaning device with a housing which has at least one air intake region for sucking air into the housing and at least one air blow-out region for blowing the air out of the housing, the at least one air blow-out region extending along an arc of an outer circumference of the housing and having a first end and a second end,
wherein a cleaned blow-out air stream can be directed through the at least one air blow-out region towards a body of a user,
wherein the housing is held rotatably on a fastening about a central axis,
wherein the housing is approximately disc-shaped in the form of a round or oval or polygonal disc,
wherein the air intake region and the air blow-out region are arranged in the same radial plane on the outer circumference of the housing,
wherein the device comprises at least one fan wheel configured to be rotatable around a fan rotation axis and at least one air intake filter arranged in the housing to filter the air sucked in by the air intake region, the at least one air intake filter being disposed so as to partially surround the at least fan wheel, and
wherein the fan wheel sucks in the air in at least one direction parallel to the fan rotation axis into the fan wheel when in operation and blows the sucked-in air away from the fan wheel in at least one direction radial to the fan rotation axis,
wherein the housing further comprises a barrier wall extending in a radial direction between the at least one air intake filter and the at least one fan wheel,
wherein the barrier wall and the fan wheel are configured such that an air stream of the air sucked in by the fan wheel passes through the air intake region into the housing relative to the fan rotation axis in a radial direction into the at least one air intake filter and then at least as well in directions parallel to the fan rotation axis around the barrier wall to the fan wheel,
wherein the barrier wall partially encloses a receiving space for the fan wheel and the fan wheel is arranged eccentrically in the receiving space, and
wherein the at least one air intake filter continuously extends from the first end of the air blow-out region to the second end through the air intake region.
2. The personalized air cleaning device according to claim 1 , wherein the air intake region and/or the air blow-out region, viewed from a fan rotation axis, are arranged on a radially outer edge of the housing.
3. The personalized air cleaning device according to claim 1 , wherein the air intake region and the air blow-out region are arranged in a region of a circumferential annular groove arranged in a central region of the housing on the outer circumference.
4. The personalized air cleaning device according to claim 1 , wherein the air intake region and the air blow-out region, viewed from a fan rotation axis, are arranged in mutually different regions of a radially outer edge of the housing, respectively.
5. The personalized air cleaning device according to claim 1 , wherein the housing has a sequence of blades in the at least one air intake region and/or in the air blow-out region, air being able to be sucked into the housing between the blades in the at least one air intake region and air being able to be blown out of the housing between the blades in the air blow-out region.
6. The personalized air cleaning device according to claim 1 , wherein the fan wheel is arranged in an interior space partially surrounded by the at least one air intake filter.
7. The personalized air cleaning device according to claim 6 , wherein, seen in a plan view from direction parallel to the fan rotation axis, the at least one air intake filter only partially surrounds the interior space in which the fan wheel is arranged and is C-shaped.
8. The personalized air cleaning device according to claim 1 , wherein, seen in plan view from direction parallel to the fan rotation axis, in a section remaining free of the air intake filter there is arranged a blow-out space into which the fan wheel in operation blows the air on the way to the air blow-out region of the housing.
9. The personalized air cleaning device according to claim 7 , wherein the C-shaped at least one air intake filter consists of several segment-shaped filter parts.
10. The personalized air cleaning device according to claim 1 , wherein the housing has a circular or oval or polygonal outer contour in a view from direction parallel to a fan rotation axis.
11. The personalized air cleaning device according to claim 1 , wherein the housing is designed optionally as a tabletop unit, as a wall unit or as a floor unit.
12. The personalized air cleaning device according to claim 1 , wherein the air cleaning device is designed as a room air cleaner and/or as a tabletop appliance, in which the arrangement of the fan takes place wholly or partly within one or more surrounding filters, and the air intake region and the air outlet region are arranged on the same circumferential plane.
13. The personalized air cleaning device according to claim 1 , wherein the air cleaning device additionally comprises a heating element and/or a cooling element and/or an air humidifying element.
