Definitions

  • the invention relates to an air mover device and a method of controlling such air mover device.
  • an air mover device for drying damp rooms comprises a housing having an air inlet and an air outlet.
  • a rotor which generates airflow between the air inlet and the air outlet is arranged in the housing. Upstream of the air outlet a turbine driven by a motor is disposed, the airflow generated by the rotor absorbing waste heat from the motor.
  • hot air flows through the air outlet into the room to be dried.
  • air is pumped through a passage via the turbine.
  • the passage is connected to a base plate spaced apart from a floor of the room, whereby air provided between the floor and the base plate is sucked toward the passage. A convective flow occurs between the floor and the base plate to remove the humidity prevailing in the floor.
  • an air mover device includes - for drying a surface, especially a damp wall or wall portion - at least one air mover for generating airflow.
  • the airflow is controllable by an adjusting unit which has such configuration that the airflow is automatically controllable into any direction of the room.
  • This solution has the advantage that high dynamics of the ambient air are developed by varying the airflow into any directions of the room, whereby dehumidifying of the walls or wall portions is accelerated by reason of high convection. Energy is saved by the more rapid drying process of the walls or wall portions.
  • the adjusting unit is controlled by an Electronic Control Unit (ECU), thus allowing control, for instance, of different motion patterns of the airflow.
  • ECU Electronic Control Unit
  • At least one sensor which serves especially for detecting humidity and/or a temperature of a wall, a wall portion or other surfaces.
  • the airflow is controlled in response to a measuring signal of the at least one sensor transmitted to the ECU.
  • the airflow can be directed primarily to a damp area of the wall measured by the sensor and the wall can be dehumidified substantially in this area by convection. If the temperature and/or humidity value of the wall then falls below a predetermined value, the air mover can be switched off, for instance, in order to save energy.
  • a plurality of sensors is provided for measuring the humidity of one or more walls or wall portions, whereby it is possible, for example, to always direct the airflow to the dampest wall portion or the dampest wall.
  • the measuring signal can be transmitted extremely flexibly through wireless connection from the sensor to the ECU. This is carried out, for instance, electromagnetically, optically or acoustically. Also, a wire connection could be used between the sensor and the ECU and in this way, compared to the wireless connection, a transmitter and a receiver could be saved.
  • a position of the at least one sensor can preferably be transmitted to the ECU via a GPS signal received by the sensor or is manually entered into the ECU via a control panel.
  • the air mover includes a rotor driven by an electric motor which is movable by the adjusting unit for varying the flow direction of the airflow.
  • a first swivel axis extending approximately transversely to a drive axis of the rotor and a second swivel axis extending approximately transversely to the first swivel axis are provided.
  • the rotor is pivoted by conventional and inexpensive geared motors assigned to the swivel axes.
  • the swivel axes may be operatively connected to a respective rotary encoder to determine the current flow direction of the airflow. Said rotary encoders then report the respective swivel angle to the ECU.
  • At least one further air mover may be provided to generate a further airflow, the latter then being aligned with respect to the first airflow so as to form turbulence in the room.
  • the flow direction and/or the flow rate and/or the temperature of the airflow is controllable.
  • the flow rate is then varied, for instance, by the rotational speed of the rotor and the temperature can be adjusted, for example, by a heater operatively connected to the airflow.
  • the airflow is directed approximately in the direction of the sensor reporting the highest reading of humidity. In this way, drying of a wall or a wall portion is possible within a short drying period, as the convection due to the airflow is most efficient in the area of the highest humidity, which entails saving of energy.
  • the airflow is alternately directed approximately toward each sensor, the period of flow during which the airflow is directed approximately to one of the sensors depending on the measured humidity of said sensor or all sensors.
  • the airflow is varied in a pattern predetermined by the ECU.
  • an air mover device 1 comprising two sensors 2 according to an embodiment is shown in a perspective view.
  • the sensors 2 are fixed to a surface 4 shown in sections, which are, for instance, damp areas in rooms, such as walls, wall portions, ceiling or floors.
  • the at least one air mover device 1 preferably serves for the drying of damp walls or wall portions of a room or other surfaces during construction, for instance in order to eliminate damage of a building by water.
  • the air mover device 1 comprises an air mover 6 having a rotor unit 7 which is pivoted through a fixing bracket 8.
  • the fixing bracket 8 in turn is rotatably mounted to a base 10.
  • the rotor unit 7 has a hollow cylindrical rotor housing 12 encompassing a rotor 14 or rather fan, wherein a housing axis and a rotor axis extend substantially coaxially with respect to each other.
  • the rotor 14 includes plural blades 16 fixed to a rotor head 18.
  • the rotor 14 is driven, for instance, by an electric drive motor not shown in the figure.
  • An airflow extending approximately axially with respect to the rotor axis of the rotor 14 is generated by rotation of the rotor 14.
  • the air is conveyed from the rotor 14 via an inlet 20 of the rotor housing 12 to an outlet 22.
  • the hollow cylindrical rotor housing 12 has a bearing on the flow direction of the airflow downstream of the outlet 22.
  • the rotor housing 12 is pivoted about a first swivel axis 24 between the approximately U-shaped fixing bracket 8.
  • the swivel axis 24 extends approximately perpendicularly to the housing axis or rotor axis.
  • At least one or two electric geared motors 26 disposed at end portions of the fixing bracket 8 support and swivel the rotor housing 12.
  • the fixing bracket 8 is supported at the base 10 via a further geared motor 28 and by the geared motor 28 is rotatable about a second swivel axis 30.
  • the latter is arranged approximately perpendicularly to the floor area and to the first swivel axis 24.
  • the rotor unit 7 is rotatable about the swivel axis 24 and about the swivel axis 30 of the fixing bracket 8 in all directions of the room so that the airflow can be aligned in any direction.
  • the airflow generated by the rotor 14 serves for drying the damp surfaces 4.
  • the airflow is directed to a surface 4 to be dried. In this way, a convective flow is generated at the surface and thus the surface 4 is dehumidified.
  • the sensors 2 include a rod-shaped sensor portion 34 inserted in a recess 32 of the surface 4 respectively. Said sensor portion 34 is used for measuring the relative humidity and/or temperature in the surface 4 in the area of the recess 32.
  • the sensor 2 moreover has a sensor unit 36 projecting away from the surface 4 and including a transmitter through which the reading - i.e. the humidity and/or temperature of the wall portion - is transmitted as measuring signal 38.
  • the measuring signal 38 is received and processed by an Electronic Control Unit (ECU) 40 disposed in the base 10 of the air mover 6.
  • the ECU 40 can also be a separate device positioned in an additional housing.
  • the latter detect the swivel angle and the swivel direction of the rotor unit 7 with respect to the two swivel axes 24, 30. They are arranged, for instance, in the area of the geared motors 26, 28. The swivel angle and the swivel direction are transmitted to the ECU 40 in the form of an electric signal.
  • the directions of the rotor unit 7 and/or the airflow to the respective sensors 2 are stored in the ECU 40.
  • the rotor unit 7 is alternately aligned toward each sensor 2 prior to the start of a drying process and the respective position of the rotor unit 7 - detected by the rotary encoders 42 - is stored along with a sensor identification of a respective sensor 2 in a memory connected to the ECU 40.
  • the data are stored by the fact that, after a respective alignment of the rotor unit 7 toward one of the sensors 2, a user confirms them through a control panel 44 connected to the ECU 40 and the corresponding swivel angles of the rotor unit 7 and the sensor identification of the sensors 2 are then stored in the memory.
  • each sensor 2 transmits its GPS position to the ECU 40 which then can swivel the rotor unit 7 in the direction of each sensor 2.
  • GPS Global Positioning System
  • the ECU 40 receives the measuring signal from each sensor 2 and processes the same. Accordingly, the sensor 2 measuring the highest humidity is determined, for instance. Then the ECU 40 controls the rotor unit 7 via the geared motors 26, 28 so that the airflow passes in the direction of the sensor 2 having the highest measuring value for humidity.
  • the ECU 40 delivers a signal to the outside, for instance to a hand-held phone, with several information, for instance the actual condition of the drying process ("moisture in %" or "end of operation, room dry”).
  • the delivering of the signal can be made by a GSM (Global System for Mobile Communication) module which is connected with the ECU 40.
  • GSM Global System for Mobile Communication
  • FIG. 2 shows a flow diagram of a method of controlling the air mover device 1.
  • the ECU 40 calculates the highest reading of humidity and in a second process step 48 the airflow generated by the air mover 6 is directed by the ECU 40 approximately in the direction of the sensor 2 reporting the highest reading of humidity. The higher the humidity in the wall portion, the more humidity is removed by convection.
  • These steps 46, 48 are repeated shown by the arrow 50 in figure 2 .
  • the ECU 40 directs the airflow to the other sensor 2.
  • the airflow always points to the direction in which the highest humidity of the surface 4 is measured and thus the largest quantity of humidity can be removed, whereby rapid and thus energy-saving drying of the surface 4 is permitted.
  • the air mover 6 alternately directs the airflow approximately in the direction of each sensor 2.
  • the period of flow during which the airflow passes in the direction of a sensor 2 depends on the humidity measured by said sensor 2 in proportion to the readings of humidity of the other sensors 2. For instance, the higher the humidity measured by a sensor 2, the longer is also the flow period during which the respective wall portion is aired by the airflow.
  • the flow period is calculated by the ECU 40.
  • air mover devices for example two, can be employed. They can be arranged in a room in such way that turbulence occurs.
  • the air mover 6 in figure 1 can also have an integrated heater controlling the airflow temperature.
  • the sensors 2 can relay information about the airflow temperature to the ECU 40 which can decide whether the addition of thermal energy from the integrated heater is required. If the airflow is heated by the integrated heater the fan speed of the air mover 6 can change the air-off temperature of the airflow. The higher the fan speed the lower the temperature of the heated airflow. Alternatively it could be controlled the heater on/off time, for example by a constant airflow or fan speed.
  • the invention discloses an air mover device for drying damp walls or wall portions by at least one air mover.
  • Said air mover generates airflow which is controllable by an adjusting unit.
  • the adjusting unit is designed so that the airflow can be automatically controlled toward any direction in the room.
