Definitions
- the invention relates to a fan assembly and a fan with a variably adjustable connector outlet.
- the invention is therefore based on the object of overcoming the aforementioned disadvantages present in the prior art and of making a variable connection possibility of a fan possible in a simple and inexpensive manner.
- a fan assembly comprising a fan housing with a housing cover rotatably mounted on the fan housing on which the connector connection is located, preferably a stator assembly (an electric motor) with windings mounted on the housing cover, the windings of which are provided electrically via the connector can be connected, for this purpose a plug connector is provided on the housing cover, the position of which can be changed and / or adjusted with respect to the fan housing by rotating the housing cover by an angle of rotation a.
- a stator assembly an electric motor
- a desired orientation or mounting position can be Implementation of the connector in the angular range between 0 ° and 360 ° in relation to the central axis of rotation of the housing cover.
- a configuration in which the plug connector is formed integrally, in particular with a material fit with the housing cover, is particularly advantageous.
- the housing cover not only forms a receptacle for the stator assembly, but also a housing for the contact carrier and the contacts of the connector.
- the housing cover is preferably pot-shaped with a cover plate and a circumferential cylindrical wall (pot wall) with an inner diameter Di. It is further advantageous if the fan housing has a cylindrical wall with an outer diameter D a , which is attached around an opening and extends outward from the fan housing. With a suitable coordination of the inside diameter and outside diameter, a sealed pivot bearing can be realized.
- cylindrical wall of the housing cover at least partially overlaps and / or encloses the cylindrical wall of the fan housing.
- Wall of the lid have a step.
- the end face of the wall of the housing is advantageously in contact with the step in the cover which forms a support for the cylindrical wall.
- a circumferential seal can be arranged between the cylindrical wall of the housing cover and the cylindrical wall of the fan housing, the coordination of the previously determined The inside diameter and outside diameter of the two cylindrical walls are then appropriately selected depending on the seal design.
- a circuit board is arranged in or on the housing cover, on which the stator assembly (and possibly motor electronics) is provided and electrical connection lines lead from the circuit board or the electrical compo len to the connector. Due to the concept of the rotatable arrangement of the entire stator assembly relative to the housing around the rotor, a variable plug position is thus easily realized.
- the fan housing is a spiral housing with a radial discharge opening.
- the opening for introducing the stator assembly is provided with the housing-side cylindrical wall on a side surface of the spiral housing through which both the axis of rotation of the stator assembly
- Housing cover and the axis of rotation of the rotor runs, these spanning a common axis of rotation.
- the plug-in connector extends radially outward with its plug-in direction relative to the center of the housing cover, the center of the cover also defining the axis of rotation.
- Another aspect of the present invention relates to a fan, in particular a radial fan, having one as described above
- Another aspect of the present invention relates to a method for
- a fastening means for fastening the housing cover in the set position is provided radially circumferentially between the housing cover and the fan housing at the same time as a sealing means for sealing the fan housing, preferably in the form of an applied sealing bead.
- Fig. 1 is a perspective view of an embodiment according to the concept of the present invention in a first and a second different plug position
- Fig. 2 is a superpositioned perspective view of a Austre approximately example according to the concept of the present invention in a first and a second different
- FIG. 3 shows a plan view of an exemplary embodiment in accordance with the concept of the present invention in a first and a second connector position that deviates therefrom;
- Fig. 4 is a perspective view of the stator assembly from Fi gures 1 to 3;
- FIG. 5 shows a perspective view from below of the stator assembly according to FIG. 4; 6 shows a plan view of the stator assembly according to FIG. 5 and
- FIG. 7 shows a sectional view through the stator assembly according to FIG. 6 along the section line AA.
- FIGS. 1 to 7 The invention is described in more detail below with reference to FIGS. 1 to 7 on the basis of an exemplary embodiment, with the same reference symbols indicating the same structural and / or functional features.
- FIGS 1 to 3 are views of an embodiment according to the concept of the present invention in a first and a second different plug position of the connector 12 ge shows. These figures each show a fan assembly 1 with a fan housing 10, namely a spiral housing with a radial discharge opening 16.
- a rotatable housing cover 11 is mounted in different angular positions in the figures of Figures 1 and 3. Furthermore, a stator assembly 20 of an electric motor is shown, which in FIG Figure 2 is shown opposite the housing in a non-assembled, superpositioned position.
- the stator assembly 20 has windings 21, as can be seen in particular in FIG.
- a circuit board 30 is also arranged on the housing cover 11, on which the stator assembly 20 is connected and from there electrical connection lines 31 lead to the plug connector 12.
- the plug connector 12 the position of which relative to the fan housing 10 can be changed and / or adjusted by rotating the housing cover 11 by an angle of rotation, is provided integrally on the housing cover 11.
- the housing cover 11 is pot-shaped with a cover plate 11a and a circumferential cylindrical wall 11b with an inner diameter D
- the connector 12 is designed as a radially lateral outlet with a plug-in direction S.
- the circuit board 30 is fastened to the inside of the cover plate 11a and has a central opening, as can be clearly seen in FIG. 7, through which a cylindrical flange 18 runs through where the
- Stator assembly 20 is mounted.
- the contacts 31 are mounted on the circuit board and their contact pins run through the cylindrical wall 11 b into the receptacle space of the connector 12, through recesses 11 d in the wall 11 b which are open toward the edge of the wall.
- the fan housing 10 has an opening 14 on the side or top surface.
- the opening 14 is surrounded by a cylindrical wall 15 extending outward from the fan housing 10, the outer diameter being smaller than the inner diameter of the cylindrical wall 11 b of the housing cover 11
- the cylindrical wall 11b of the housing cover 11 overlaps the cylindrical wall 15 of the fan housing 10 and a rotatable mounting is created.
- This can be particularly advantageous be achieved by that, as can be seen in Figures 5 and 7, the inner wall of the cylindrical wall 11b has a step 11c.
- the wall 11b thus has a first ring section, having a first inner diameter and a second ring section (separated by the step), having a second slightly larger inner diameter, which is only slightly larger than the outer diameter of the cylindrical wall 15 of the fan housing 10.
- the end face 15s of the cylindrical wall 15 then rests against the step 11c, which forms a support for the cylindrical wall 15.
- the embodiment of the invention is not limited to the preferred exemplary embodiments specified above. Rather, a number of variants are conceivable which make use of the solution shown even in the case of fundamentally different designs.
