Definitions

  • the invention relates to an evaporative humidifier with a water reservoir, with a support plate which carries an evaporation filter and a pump reaching into the water reservoir, with a motor for driving a fan and the pump and with a hood containing air inlet and outlet openings, the Motor attached to the underside of the hood and a coupling is provided between the motor and pump, by means of which the connection can be released or established automatically when lifting or putting on the hood.
  • elastic bands are provided for holding the pump shaft, their arrangement and attachment require a corresponding amount of time during assembly and which can finally be easily damaged or at least detached from their holders when cleaning the water storage container. Difficulties in handling and in particular in assembly, therefore, easily arise, especially since evaporative humidifiers in practice often have to be cleaned and assembled by people who are not very technically skilled.
  • GB-A-914466 also describes an evaporative humidifier which has a flow channel.
  • the motor and the fan are not arranged on the hood, but on an upwardly directed bottom part of the water storage container; this significantly reduces the water volume.
  • An annular interior in the area of the hood is divided into two chambers by means of an evaporator box, so that the air in one chamber passes up and in the other chamber down past the evaporator box.
  • the flow channel here delimits one of the said chambers towards the fan.
  • the object of the invention is to improve the evaporative humidifier with little effort in such a way that, on the one hand, a low overall height is achieved and, on the other hand, simple handling is ensured with a high level of functional reliability.
  • the hood is flat on its top, with the air inlet or outlet openings opening at the top, that the motor and the fan are arranged within an essentially hollow cylindrical flow channel which extends from the underside of the hood extends essentially to the fan, and that a housing is provided which surrounds the shaft of the pump and which has radially inwardly directed lugs on which the shaft is supported when the hood is lifted off.
  • the proposed evaporative humidifier has a comparatively low overall height, especially since the hood on its upper side, apart from the air inlet or outlet openings provided there, is flat and therefore there is no in-depth use or the like. Due to the arrangement of the motor and fan within the flow channel, proper air flow is ensured on the one hand and on the other hand the stability and strength of the hood is increased to a significant extent with little material expenditure.
  • the motor can thus be reliably attached to the underside of the hood without difficulty, and in order to avoid false air flows, very small distances between the fan and the flow duct can be maintained.
  • the pump shaft is supported in a particularly simple manner when the hood is lifted off, so that when the hood is put on, the connection will also be reliably established by means of the coupling. It can be seen that this provides the necessary functional reliability and that the pump will always run during operation, with damage during cleaning or when the hood is put on being reliably avoided.
  • stiffening ribs are provided on the underside of the hood and within the flow channel.
  • the flow channel is surrounded by the evaporation filter, or the flow channel protrudes into the evaporation filter, the liquid distribution arranged on the evaporation filter lerrinne is arranged substantially immediately below the underside of said hood.
  • the dimensions of the flow channel can thus be matched to the arrangement and dimensions of the fan without difficulty, while the evaporation filter and the liquid distribution channel can in turn be designed in accordance with the required moisture throughput. Since the liquid distribution channel is arranged directly below the underside of the hood, a low overall height of the evaporative air humidifier is also ensured.
  • the fan is advantageously arranged approximately halfway between the support plate and the underside of the hood mentioned.
  • the fan is located approximately in the region of half the height of the evaporation filter and therefore air drawn in through the air inlet openings will flow through the evaporation filter largely uniformly.
  • the flow channel extends from the underside of the hood to an area below the fan. This ensures in a particularly simple manner that no inadmissible eddies or flows occur in the area of the lower edge of the flow channel, which would have an unfavorable influence on the efficiency.
  • the evaporative humidifier has a box-shaped housing, as shown in Fig. 1.
  • the housing consists of a lower part in the form of a water reservoir 1 and a hood 2, between which there is a support plate 3.
  • the support plate 3 has an encircling, cross-sectionally H-shaped edge with which it rests on the water reservoir 1.
  • the hood also engages in the aforementioned H-shaped edge 4, so that there is a tight seal to the outside.
  • An evaporation filter 5 is arranged on the support plate 3, on which a liquid distribution channel 6 is arranged at the top.
  • the support plate 3 has an upward projection 7, in which a pump 8 is suspended.
  • the pump 8 contains a housing with two supporting tube halves 9, 10 and a lower, cup-shaped housing part 11.
  • the pump further contains a shaft 12 with a pump wheel 13 (not shown here in more detail).
  • the housing part 11 has openings 14 through which water from the reservoir 1 sucked in and conveyed by means of the pump wheel 13 through a hose 15 into the distribution channel 6.
  • the liquid distribution channel 6 is located directly below the underside 18 of the hood 2, so that the evaporation filter 5 has a large height or surface.
  • the hood 2 has air inlet openings 16 on the side and air outlet openings 17 at the top.
  • a schematically indicated electric motor 19 is arranged on the underside 18 of the hood 2.
  • the shaft of the motor 19, like the shaft 12 of the pump 8, is arranged essentially vertically, the shafts mentioned being aligned with one another.
  • the lower shaft end 20 is led out of the motor 19 and carries a fan 21, a hub being connected in a rotationally fixed manner to the shaft end 20.
  • the motor 19 and the fan 21 are located within a largely cylindrical flow channel 23, which is also arranged on the underside 18 of the hood 2 and is expediently made with the hood 2 from a single piece. In the interior of the flow channel 23 there are also stiffening ribs 24, through which the air flow is also guided.
  • the fan 21 driven by the motor causes an air flow in the direction of arrows 25 and 26, the evaporated water being taken along when the evaporation filter 5 flows through.
  • the fan 21 is preferably located approximately halfway between the support plate 3 and the underside 18 of the hood and thus also approximately half the height of the evaporation filter 5.
  • the housing in the plane perpendicular to the plane of the drawing can have a circular or even an elongated rectangular cross section. For this reason, the left side is only partially shown in FIG. 1.
  • all electrical devices are arranged on the hood 2, that is to say also the connecting terminals, switches, not shown here. This ensures that when the hood 2 is lifted off, all electrical devices are separated from the other parts of the evaporative humidifier.
  • the coupling 30 has a first coupling half 31 which is arranged on the lower shaft end 20.
  • the coupling half 31 is assigned a second coupling half 32 which is connected to the shaft of the pump 8.
  • the coupling half 32 contains or consists of a permanent magnet, while the first coupling half 32 consists of soft iron.
  • the magnetic coupling designed in this way is dimensioned such that a secure connection between the motor and pump and thus also a safe drive of the pump is ensured in the attached, illustrated state of the hood 2. On the other hand, when the hood 2 is lifted off, the existing connection is released, and without additional handles being required from the outside.
  • the water reservoir 1, the pump 8 and the evaporation filter 5 can then be cleaned very easily. It is therefore only necessary to remove the hood in order to separate the electrical devices including the motor from the other parts of the evaporative humidifier.
  • the clutch 30 and the adjacent parts of the pump and the fan 21 are shown enlarged.
  • the surfaces of the coupling halves 31 and 32 facing one another are essentially conical, a cone with an opposite slope being provided in the center. Due to the conical design of the two coupling halves 31 and 32, safe guiding and centering is achieved when the hood 2 is fitted or when the motor and pump are coupled.
  • the mutually facing surfaces of the coupling halves 31 and 32 can optionally (not shown) be provided with interlocking teeth in order to obtain reliable torque transmission in all cases, for example even with a weak magnet.
  • the coupling half 32 is designed as a permanent magnet and magnetized in the direction of arrow 34.
  • the coupling half 31 can also consist of soft iron or of a permanent magnet, but with the opposite magnetization device.
  • the clutch 30 is further dimensioned such that the shaft 12 or the pump wheel 13 is raised to the position shown and thus a special axial bearing of the pump is not required.
  • the pump housing or the support tube halves 9, 10 are provided with radially inwardly directed projections 35, 36. In the position shown, there is a narrow gap between the shaft 12 and the above-mentioned lugs 35, 36 and there is no contact between them.
  • the housing of the pump 8 consists of the two support tube halves 9, 10 and a lower cup-shaped housing part 11, which is connected to the support tube halves by means of a snap-in connection.
  • the housing part 11 is pulled down and the two support tube halves 9 and 10 can be pivoted away to the side. It is important that after lifting the hood 2 there is no longer a connection to the engine and the pump is freely accessible.
