Definitions

  • the invention relates to a housing according to the preamble of claim 1.
  • Such a housing is known from FR-A-2 379 970.
  • a protective housing receiving a fan and its drive motor is known, which is designed like a hollow body, which is composed of two completely identical, pot-shaped housing halves. Both housing halves are provided at their junction with a flange on which are used for their connection hooks or breakthroughs that penetrate each other when the two housing halves are joined together and get caught in one another by rotating the housing halves in opposite directions, so that a positive connection is created between the two .
  • the housing known from this document has the problem that the connection between the two housing halves without tools and thus also for unauthorized persons, such as children, can be easily broken, so that for them, due to the accessibility to the electrical connections of the drive motor for the fan, there is a risk of health damage from an electric shock.
  • the invention is based on the object of designing a housing which complies with the VDE guidelines and covers the electrical connections, is simple in construction and cannot be opened by unauthorized persons, but nevertheless allows a professional to quickly access it in the event of a fan malfunction.
  • the current-carrying parts arranged in it are protected so securely that they cannot be touched even when using different equipment, such as nails, knitting needles or the like.
  • the additional housing allows both a larger number of air passage openings in the fan housing and a greater freedom of movement with regard to their arrangement, since the walls thereof do not have to be suitable for preventing access to the electrical connections.
  • the electric drive is largely protected from contamination under the additional housing. Due to the design of the locking means, it is not possible for children in particular to disassemble the housing and thus to access the live parts, but a specialist can easily access the interior of the housing in the event of a repair using a tool even on site at a customer .
  • one of the housing parts of the fan housing has a step on its free edges which is overlapped by the free edges of the other housing part serving as a counterpart when the two are connected to one another.
  • Such a solution is characterized on the one hand by its stiffening of the housing at the connection point and, on the other hand, as a result of the housing part offset by the step, a type of guide is formed for the counterpart, which considerably simplifies the assembly of the housing parts for a person assembling the housing.
  • the standing section of the step serves as a kind of end stop, which reliably indicates to the person installing the correct position of the parts to be connected.
  • the latching means used to connect the two housing parts of the fan housing are arranged within the step Lugs that cooperate with corresponding recesses of the counterpart are formed.
  • Such locking means are characterized on the one hand in that they are arranged inconspicuously and concealed and therefore offer little incentive to open them. On the other hand, the locking means are largely protected due to their concealed arrangement against unwanted forces that could destroy them.
  • the housing can be mounted at a particularly small distance from adjacent walls if, according to a further advantageous embodiment of the object of the invention, it is provided that the fan housing formed by the connection of the housing parts has a surface which is essentially continuous over the connection point. In addition, a continuous surface can be cleaned in less time.
  • the housing parts receiving the fan are equipped with different depths, the additional housing being arranged in the lower of the two and being covered with respect to its height.
  • the additional housing in which the drive unit for the fan is arranged is surrounded by the fan housing in a protective manner, even if it is opened by removing the flatter housing part.
  • the drive is with the additional housing open, as is the case with the assembly of the housing unit the case may still be adequately protected from damage.
  • the two-part additional housing is formed from a loose and a fixed part , wherein the fixed part is formed in the lower of the two housing parts serving to accommodate the fan.
  • the drive unit for the fan is held both safely and quietly if, according to a further preferred embodiment of the object of the invention, it is provided that the loose and the fixed part of the additional housing is each equipped with a receptacle, which is used both as a bearing for the housing the drive motor as well as for damping the vibrations generated when it is running.
  • the receptacles are designed as bearing shells partially comprising the motor housing and adapted to the contour of the motor housing, the shell openings of which face each other congruently.
  • the motor is both stably supported and positively received by them and is therefore in the correct position in the additional housing fixed. Furthermore, the facing shell openings make the motor much easier to install, since it can be inserted into the bearing shells in a simple manner for its installation.
  • the bearing shells are particularly easy to assemble and store, and are securely held in the correct position within the additional housing, if, according to a further advantageous embodiment of the object of the invention, it is provided that the bearing shells are designed as identical, loose elements which are held positively and non-positively both in the fixed and in the loose part.
  • the loose part which serves as a cover, has an integrally formed shaft within which the connection poles of the drive motor are arranged.
  • connection poles of the drive motor which are supplied with current by the connecting lines are particularly secure against unauthorized access, even when equipment such as nails, knitting needles or the like is used.
  • the deeper housing part, which receives the fan is equipped on the side facing away from its free edges with a centering pin, which is in a fixed spacing relationship to a fastening means of the fan housing stands, the centering pin being matched to a bore in a holder, which is not visible in a wall or the like and on which the fan housing is held.
  • Such a solution is characterized in that the fan housing can be fastened to it without time-consuming finding out of its intended fastening position.
  • the fan housing is particularly expedient if, according to a further advantageous embodiment of the object of the invention, it is provided that the lower of the two housing parts receiving the fan on the side facing away from its free edges is provided with a molded-in strain relief for the electrical connecting line of the drive motor.
  • the air flow generated by the fan is passed through the fan housing in a particularly favorable manner if, according to a further advantageous embodiment of the object of the invention, it is provided that the flatter of the two housing parts accommodating the fan has an air duct projecting from its free edges, within which the fan wheel is arranged in this way is that the edges of the air blades facing the drive motor are essentially flush with the edge of the air duct directed towards the drive motor.

  • the exiting air flow becomes corresponding both in terms of its volume and which is simply divided according to its direction and requirements.
  • support strips 20 are provided in the form of webs arranged vertically in the edge region on the outside, which run parallel to the long sides of the rectangular contour and on the one hand to the higher, short side of the Run out housing 10 like a circular arc and on the other hand end on the long sides in the region of the transition to the circular arc approximately perpendicular to the outside of the wall 17.
  • the support strips 20 on the one hand space the wall 17 when the housing part 12 is fastened to a fastening wall, and on the other hand they serve as supports which support the wall 17 against the fastening wall.
  • the lower housing part 12 is equipped for the purpose of its attachment to the wall 17 with three corner points of an equilateral triangle, serving as part of the fastening means through holes 21, of which the highest lying approximately in the middle of the higher narrow side directly adjacent to this lies.
  • the support strips 20 which run out in the form of an arc contribute to if the housing part 12 is fastened with these in a transition of two walls meeting one another, which is adapted to the shape of the arc of a circle - for example in the interior of a cooling device.
  • the circular arc-like outlet of the support strips 20 is brought into contact with this transition, whereby a degree of freedom of the housing part 12 is fixed.
  • the deeper housing part 12 is equipped at the free ends of its walls 18 surrounding the interior with a step 23, which is produced by reducing the wall thickness of the walls 18 from the outside, so that the inside of the walls 18, unaffected by the step 23 , is essentially flat.
  • the height of the step 23 is such that it is adapted to the wall thickness of the free ends of the walls 15 of the flatter housing part 11, so that the outside of the walls 15 with housing parts 11 and 12 joined to the housing 10, the walls of which are in this state with their free ends overlap, do not protrude from the outside of the walls 18 and result in a continuous housing surface extending beyond the connection point.
  • detent lugs 24 belonging to a latching connection are arranged, which are distributed approximately at equal intervals from one another on the circumference of the step 23 in order to ensure a uniform connection between the housing parts 11 and generate 12.
  • the locking lugs 24 have an essentially triangular cross-section, the two catheters, which are provided with different lengths, being perpendicular to one another, and the hypotenuse of the triangle enclosing an acute angle to the two cathets.
