Definitions
- a wall ring can be used, which is inserted into a corresponding wall opening and may have receiving means for the fan. Furthermore, the wall ring can realize other functions such as the power supply to the fan motor.
- the protective grid with the wall ring
- guard and wall ring can be made in one piece, for example, as a plastic injection molded part.
- the advantage here is that the protective grid does not have to be fixed in a separate assembly step.
- a disadvantage is the expensive injection molding tool required.
- the protective grid can not be removed without destruction, so that, for example, maintenance work can only be carried out by the side of the wall opposite the protective grid. If maintenance work can not be performed from this side, for example because this side can not be reached by maintenance personnel or maintenance must be performed from the other side, the entire fan with its receiving system has to be removed from the wall, which requires a great deal of effort.
- the protective grid must be manufactured with relatively thick bars, whereby the free cross-section for the air flow forcibly reduced, whereby the efficiency is reduced and the mileage is negatively affected.
- the wall ring and guard may be two separate components, with the guard must be mounted on the wall ring.
- the protective grid is connected via a non-positive screw connection with the wall ring, wherein by the screw head and possible washers a height increase takes place, which is disadvantageous in tight installation conditions.
- the installation requires increased effort, with additional loose parts such as screws and possibly washers are installed, which must be included and can also be lost.
- US 4,724,747 A discloses a recording system according to the preamble of claim 1.
- the object of the invention is to provide a low-cost recording system with a wall ring and a protective grille, wherein wall ring and protective grid are non-destructively separable and at the same time to be easy to install and with the demountability of the protective grid no negative effect on the height of the recording system should occur. According to the invention this object is achieved by a recording system according to claim 1.
- An inventive receiving system for a fan with a protective grid with at least one circumferentially arranged protective grid strut and a wall ring with a first end face is characterized in that the wall ring at least a first connecting element on the first End face and the protective grid has at least a second connecting element, wherein the first connecting element with the second connecting element is operatively connected and the second connecting element sunk in the first end face of the wall ring is arranged and wherein the wall ring further comprises at least one motor support strut and the motor support strut a Has damping toothing, in which the at least one protective grid strut is submersed.
- the first end face of the wall ring is the end facing the protective grid.
- Protective grid supported on the wall ring via the operative connection of the first with the second connecting element.
- the at least one grille strut may be arranged substantially spirally between the wall ring as an outer boundary and the axis of the fan.
- the at least one protective grid strut may be round or in the form of a polygon.
- the cross section of the at least one protective grid strut can be made substantially round or polygonal, wherein the corners can also be performed rounded.
- the grille attachment does not build on the frontal contour of the wall ring out on.
- the motor driving the fan blades can be supported in the wall ring. It has proved to be particularly advantageous if the wall ring has several, for example two or more motor support struts.
- the motor is held securely by the at least two motor support struts.
- the engine mount strut has a damping toothing, in which the at least one protective grid strut is submersible. This addresses the problem that a substantially flat protective grid has a certain vibration or vibration susceptibility. Due to the damping toothing in the motor mounting strut, the at least one protective grid strut of the protective grid can be accommodated in such a way that they rest in the damping toothing and the vibrations occurring during operation are effectively damped
- the first connecting element has at least one flexible undercut with an undercut, wherein the second connecting element can be snapped into the undercut. Due to the flexibility of the undercut, the second connecting element can be snapped behind the undercut and also be snapped back by bending the undercut, whereby the protective grid can be dismantled without destroying.
- the installation by snapping is tool-free and easy, which minimizes the assembly work.
- Flexible undercuts are also inexpensive to produce in the production of the wall ring.
- a flexible undercut in the production of the wall ring can be formed in one operation with.
- the second connecting element is arranged on a radial strut of the protective grid.
- the radial strut extends in the radial direction of the protective grid.
- the second connecting element represent an extension of the radial strut.
- the extension can continue in the radial direction or can also be arranged at approximately 90 ° in the direction of the wall ring on the radial strut. In this case, the extension of the radial strut may be bent over.
- the extension can also be attached as an initially separate component to the radial strut, for example, be attached cohesively.
- the second connecting element can also be attached at any point of a protective grid strut and does not have to represent the extension of a radial strut.
- the protective grid is mounted on the wall ring.
- the radial strut may also have the function of supporting at least one circumferentially extending guard rail strut. For this purpose, it can be operatively connected to the at least one protective grid strut.
- the radial strut can be soldered or welded to the at least one protective grid strut.
- the flexible undercut is designed as acting in the circumferential direction snap hook.
- a counter-position for the radial strut be provided so that the radial strut is supported in the circumferential direction between the snap hook and the counter-position.
- the flexible undercut can also be designed as acting in the radial direction snap hook.
- the flexible undercut can be designed as a cylindrical snap hook.
- Such a cylindrical snap hook can for example be designed as a bore, wherein the flexible undercut can be molded, for example by injection molding on a punch with a corresponding paragraph. The flexibility can be achieved in this case on the material properties of the wall ring.
- the first connecting element is designed as a cylindrical bore, wherein the second connecting element has a flexible undercut.
- the second connecting element can be designed as a dowel, wherein the flexibility represents a property of the dowel, which is plugged through the through hole so far that an undercut, for example in the form of a hook snaps behind the wall thickness of the through hole.
- a hook for example, serve a flexible arm, which leans against the plug when passing through the through hole to the anchor and springs up behind the through hole.
- the dowel itself may have a cavity, so that the Dübelwandung at the point at which an at least segmental existing undercut is available as an increase in diameter, can press into the cavity and rebounded again, as soon as the point with the increase in diameter is pushed through the through hole.
- an attachment via a push button construction is conceivable.
- the wall ring has at least three distributed over the circumference first connecting elements and the protective grid has at least three equally distributed over the circumference and operatively connected to the first connecting element second connecting elements.
- the wall ring is made of a plastic material.
- the wall ring can be made of a thermoplastic by injection molding, which allows a particularly simple and inexpensive production of the wall ring with complex geometry, for example, the first end face.
- the protective grid is made of a metal material.
- the protective grid can also be made of a plastic material, for example a thermoplastic by injection molding.
- the protective grid is flat in one embodiment, so that it does not protrude in the assembled state in the axial direction over the contour of the first end face of the wall ring.
- the protective grid is designed axially in the direction of the wall ring, that is, convex in the direction of the built-in wall ring fan.
- the protective grid is biased and immersed in the mounted state in the damping teeth of the motor support strut and does not protrude in the axial direction beyond the contour of the first end face of the wall ring.
