Definitions

  • the invention relates to a humidifier with an at least two-part housing, wherein the housing has an inlet opening and an outlet opening for an air flow, a fan with a drive motor, a water tank and a carrier element with a humidifying mat, wherein the carrier element is connected to a float element, which dips into the water tank and the water tank is arranged in a lower housing part.
  • a humidifier of this type is known from CH 669 251 A5.
  • This humidifier consists of a two-part housing, whereby the lower housing part simultaneously forms a water tank.
  • inlet openings for the air are arranged on side areas.
  • an outlet opening for a humidified air flow is present, wherein in this area, a fan is arranged with a motor which is surrounded by a downwardly directed air passage.
  • a support element is arranged, which carries a moistening mat and is equipped at the bottom with a float element.
  • the carrier element is connected to a guide tube, which is displaceably guided on the air channel.
  • ADJUSTED SHEET (RULE 91) ISA / EP Floats on the water in the water tank, with a lower portion of the wetting mat dipping into the water and absorbing water.
  • the water should be able to be filled directly into the humidifier from above and through a sufficiently large opening, and the level of water in the water tank should be displayed directly in the filling opening without additional level indicator.
  • the filling opening should be closed when the maximum level of water in the water tank is reached.
  • the humidifier should have a low center of gravity.
  • the inventive humidifier has in the direction of a vertical central axis on an upper and a lower housing part, wherein in the bottom region of the lower housing part, the inlet opening for the air flow and at an upper End region of the upper housing part, the outlet opening for the humidified air flow are present.
  • a first air channel is subsequently formed at the inlet opening and concentric with the vertical central axis, and the fan is arranged in this first air channel.
  • the first air duct is passed through the water tank and the water tank is arranged concentrically around this first air duct.
  • the air flow is thereby guided in an advantageous manner substantially vertically from bottom to top through the housing of the humidifier.
  • a further embodiment of the invention provides that in the direction of the central axis above the water tank, the carrier element is arranged with the moistening, wherein at least a lower portion of the support member encloses the upper portion of the first air channel and an inner wall of the water tank and this support member the moistening mat is displaceable in the direction of the central axis.
  • the support member is not in communication with the upper housing part of the humidifier, but is guided in a movable manner over the walls of the air duct in the vertical direction. This makes it possible that the upper housing part can be lifted off the lower housing part, without having to lift off components which are in contact with water. Even when placing the upper housing part on the lower housing part there is the advantage that in addition to the two housing parts no other components must be assembled and fitted together.
  • an inlet Casting funnel is formed for the water with a central opening and this funnel forms a second air channel. It is also advantageous if, in the direction of the vertical central axis above the carrier element with the moistening mat, a cover hood with a central, upwardly directed closure element is present, this cover hood being displaceable in the direction of the central axis and connected to the carrier element for the moistening mat. The closure element on the cover cooperates with the central opening on the pouring funnel.
  • the closure element is designed, for example, in the form of a pin or in another suitable form, that it projects into the pouring funnel from below in a vertical direction when the carrier element and the cover hood are in the upper region of their vertical displacement path. At the same time closes the closure element in the uppermost position of the support element and the cover the central opening of the sprue. In this way it is possible that water can be poured into the humidifier through the pouring funnel until the water tank is filled and the highest water level in the water tank is reached. Since the carrier element is connected to the float element and floats on the water in the water tank, it is displaced upward with increasing water level.
  • the covering hood connected to the carrier element is also displaced upward with the closure element until the closure element closes off the central opening of the pouring funnel.
  • the height of the water level in the water tank on the position of the closure element in the pouring funnel can be seen. If, despite reaching the highest level in the water tank still filled with water into the pouring funnel, this remains in the hopper and it is immediately apparent that the water tank is filled. By this configuration, no additional water level indicator is necessary and the filling of water is greatly simplified and the risk of spillage of water is largely avoided.
  • the water tank is a component independent of the lower housing part, which component can be removed from the lower housing part. This allows easy cleaning of the water tank or its replacement, if it should be too dirty.
  • a further embodiment of the invention provides that a third, annular air duct is formed around the pouring funnel on the upper housing part and this third air passage communicates on the one hand with an air guide space arranged around the moistening mat and on the other hand with the outlet opening on the upper housing part.

  • the cover protrude in the radial direction over the moistening mat and is equipped with a guide edge for the water flow.
  • This guide edge serves to ensure that the water, which flows over the surface of the cover, is directed inwardly against the outer surface of the moistening mat and thereby wets the moistening mat. If the wetting mat no longer absorbs any water, it will flow down into the water tank.
  • the water container can thus be filled in a simple manner by pouring water into the pouring funnel at the outlet opening during startup.
