Definitions

  • the invention relates to a fan heater with a housing for receiving a blower and an electrical heating register, the housing of which can be pivoted and rotated to achieve changes in direction of the blower exhaust air flow on a foot part and is formed by a prismatic front housing part having an exhaust opening and a rear housing part with supply air openings is.
  • this object is achieved in that the rear housing part is truncated pyramid-shaped, that the supply air openings extend over a partial height of the opposing upright side walls of the rear housing part and that the supply air openings are overlapped by a number of strips formed next to one another.
  • a further supply air opening is provided in the upper Seikenwand and / or the rear rear wall of the rear housing part. This provides the possibility that an adequate supply air supply is reliably guaranteed even when several housing surfaces are covered.
  • the supply air openings and the supply air opening-free surface sections of the rear housing part are overlapped by a number of spaced strips which extend over the entire extent of these surfaces.
  • the strips form air channels, which are in the direct wall position of the housing are permanently open in the area of the front ends and provide for the supply of blown air via the ends.
  • the foot part is designed as a spherical section.
  • the housing adjustable on the spherical section can preferably be fixed by frictional force on the foot part in the upright position as well as on the pivoting and / or rotating positions. To achieve a wide range of exhaust air, it is advantageous to make the housing oscillate on the foot part.
  • the truncated pyramid-shaped housing part interchangeably carries plate-shaped air filters which grip over the supply air openings.
  • the plate-shaped air filters are formed by filter mats enclosed by frames.
  • the filter mats can be made of textiles or porous plastics. It is also possible to design the air filters as bipolar filters or as electrostatic filters.
  • the air filters can be assigned to the air passage openings after the rear housing part has been removed from the front housing part.
  • the truncated pyramid-shaped housing part is preferably provided with through-openings for the air filters in the side walls extending between the side walls having the air inlet openings.
  • the through openings arranged in the housing parts are expediently closable by means of pivotable, displaceable or pluggable closing bodies.
  • the air filters can also themselves, for example, have approaches as handles.
  • the filters can be replaced at predetermined intervals. Precise air filtering can, however, be achieved if the housing parts have an automatically triggerable optical and / or acoustic indicator for a necessary filter change.
  • a filter change indicator can respond, for example, to changes in vacuum in the housing parts. The changes in vacuum arise due to more or less severe clogging of the filter passages by dust particles or the like. a. It is also possible to make the filter change indicator controllable depending on the size of the flow speed of the fan air. Changes in flow velocities occur when the filter cross-sections of the filter openings are changed due to clogging by dust particles.
  • the front housing part has a flat front and in the direction of flow of the blower air at a distance behind the exhaust air openings has a housing opening extending over the exhaust air openings, that in the housing opening between two end positions, a number of air guide strips are set next to one another are that together close the housing opening in one end position and form a front side section and in the other end position, there are passages between them for the blower air.
  • the fan heater can thus deliver blown air to the room in accordance with the swivel positions of the air duct strips and the size of the passages with different pressure numbers and flow rates.
  • the air duct strips allow the air flow to be aligned and, when in the closed position, help protect the blower against dust.
  • the air guide strips are expediently arranged in the housing opening so as to be pivotable about parallel vertical axes.

  • the air guide strips are preferably made with an essentially rectangular cross section over their length. There is the possibility that adjacent air guide strips overlap each other with overhangs or the like extending beyond the upright side surfaces thereof and thus contribute to a tight covering of the housing opening.
  • the air guide strips have a cross-sectional shape with essentially a right-angled triangle and that the ends of the cross section of the air guide strips, which are approached at right angles, accommodate the pivot axes for these.
  • the air guide strips in one piece or by halves divided in the central longitudinal plane thereof. the one with the other. e.g. are firmly connected by gluing or welding.
  • the latter designs of the air guide strips provide the prerequisite for a simple configuration of the same.
  • the air guide strips are especially molded or injection molded from plastic, e.g. formed by extrusion molding and optionally provided with coatings of paint or metals.
  • the air duct strips are mechanically and chemically protected by the covers.
  • the air guide strips can be pivoted individually, independently of one another, manually or by a motor. This makes it possible to close the housing opening or to open it in whole or in part. It is further provided that the air guide strips are connected to one another by mechanical means and that they can be swiveled together manually or by a motor at the same time.
  • the simultaneous pivotability of the air guide strips leads to a particularly simple and quick actuation of the same and facilitates the alignment of the fan air flow.
