Description

The invention relates to a slide for adjusting and fastening a fan in a ventilation device, a system comprising a slide and a condensate tray for adjusting and fastening a fan, and to a corresponding ventilation device.Ventilation devices are also being used more and more in private houses. In this case, maintenance must be carried out regularly, usually by persons skilled in the art. In particular after the installation of a ventilation device, it may be necessary to subsequently insert, adjust and / or fasten some components of the ventilation device. This also relates to the fan, for example.For the functionality of the ventilation device, it is essential that the air to be guided is guided in a sealed air guide. After a possible insertion / maintenance / replacement of the fan, therefore, certain requirements for the tightness between the fan (or the fan housing) and further components of the air duct, for example an air duct, have to be fulfilled, which must be achieved by adjusting and fastening the fan by persons skilled in the art. Above all, a closed air duct must (again) be produced, which makes it possible for air to flow efficiently through the fan. For this purpose, corresponding seals are used between the fan (or the fan housing) and further components, such as an air duct located on the fan, which then have to be compressed accordingly, so that no air can enter or leave.In the prior art, the fan or the fan housing is fastened in the installation space of the ventilation device provided for this purpose. For example, the fan is turned into a frame and locked there. The fan can also be fastened, for example screwed or riveted, in the installation space to surrounding components, as well as to a further component forming the air duct. Additionally or alternatively, eccentric pins may be used.Due to tolerances in the installation space of the ventilation device, at least one height of the installation space for the fan usually varies, as a result of which leakage, i.e. leakage, of the fan can then occur when the fan is installed or, in extreme cases, the fan cannot be installed at all.The known methods accordingly have the disadvantage that possible tolerances which can occur in the installation space of the ventilation device cannot be compensated. In other words, the requirements for precise dimensions of the components used for the installation space are very high in order to ensure precise installation of the fan and thus also tightness of the fan housing. It is also not possible to compensate for subsequent relaxation of the components or of the fan housing, which is usually produced from plastic. However, relaxation can mean loosening of the tightness, which can then lead to an entry and / or exit of air. In particular, the invention provides a solution for the precise adjustment of the fan without high requirements being placed on the dimensions of the components surrounding the fan housing and being able to be compensated by the subsequent relaxations, which possibly cause a leakage of the fan housing.According to the present invention, in a first aspect, there is provided a slider as defined in claim 1, namely a slider for adjusting and fixing a fan in a ventilator, the slider having a front end and a rear end, and further having an upper surface and a lower surface, the lower surface being oblique to the upper surface so that a plane describing the upper surface and a plane describing the lower surface intersect toward the front end, the slider further having a recess, the recess being disposed at the rear end, an upper wall of the recess being substantially parallel to the upper surface, and a lower wall of the recess being substantially parallel to the lower surface, the slider further having a tooth portion, wherein the tooth portion is disposed on the lower surface in a rear end portion and has teeth protruding from the lower surface.The slide is in particular configured to be pushed between the fan and a condensate trough of the ventilation device in order to adjust and fasten the fan in the ventilation device. The configuration can be achieved in particular by the described structural features.After the fan is installed in the ventilation device, the slider can be pushed under the fan and thus push the fan upward (in a sealing direction). The oblique arrangement enables the fan to be displaced upwards by pushing the slide in a direction perpendicular to the sealing direction, in particular without the fan tilting in the process. The toothed region enables a sequential locking of the slide and thus of the fan, so that a small-step adjustment of the fan is possible. The recess enables the slide to yield according to the force acting on the slide through the fan and the condensate tray, and by increasing the force on an upper region and a lower region of the slide, the tooth region is released and thus the slide is removed. In particular, the slide according to the invention prevents a seal between the fan, i.e. the fan housing, and a further component, for example a separating part, from being subject to shear. As a result of a load on thrust, the seal could be displaced or damaged and, if appropriate, tightness could no longer be provided. The invention thus reduces stress on the seal between the fan and the further component.It should already be noted here that the slide does not necessarily have to be slid between the fan and the condensate trough, but instead a corresponding extra component can also be provided as an alternative to the condensate trough.The slide preferably has a wedge-shaped basic shape, wherein the slide comprises an upper surface, a lower surface, a front surface, a rear surface and two side surfaces by means of its orientation in the ventilation device. The front surface is arranged at the front end and the rear surface is arranged at the rear end. Further, the upper surface is disposed at the upper portion and the lower surface is disposed at the lower portion. The corresponding orientation of the slide corresponds to the orientation of the slide in the installed state of the slide in the ventilation device.Furthermore, the slide preferably has an elongate extent, as a result of which a longitudinal axis is defined, which is preferably oriented along a sliding direction.The slider has a front end and a rear end, wherein the slider can be slid in a sliding direction between the fan and a condensate tray, wherein during the sliding operation the front end of the slider leads the rear end of the slider. The front end and the rear end each correspond to a part of the slide with an imaginary central vertical division of the slide perpendicular to the longitudinal axis of the slide.The upper surface and the lower surface are each described by a plane, the planes intersecting toward a front end of the slider. A cutting axis of the plane can lie in particular outside the slide, wherein the cutting axis preferably runs parallel to the plane which describes the upper surface.The slide according to the invention has a recess which in particular has a wedge-shaped basic shape, i.e. the volume defined by the recess is wedge-shaped. Preferably, the recess is substantially parallel in cross-section to the upper surface of the slider. Furthermore, the recess preferably extends over an entire width of the slide, i.e. from one side face of the slide to the other side face of the slide. In this case, the cross section of the cutout is preferably the same over the width. The recess is arranged at a rear end of the slide, preferably in a lower region of the rear end of the slide. The lower region and an upper region of the slide correspond in each case to a part of the slide with imaginary central horizontal division of the slide along the longitudinal axis of the slide.The toothed portion is arranged on the lower surface of the slider, wherein the toothed portion is arranged on the lower surface in a region of the rear end, i.e. at the rear end, of the slider. The tooth region has teeth which project from the lower surface, in particular project perpendicularly. The teeth preferably have a triangular cross-sectional area, wherein the triangular cross-sectional area preferably has an undercut, i.e. the cross-sectional area is preferably undercut-triangular. The largest angle of the triangle is preferably arranged in the direction of the rear end of the slider. Alternatively, the triangular cross-sectional area can also be described by a right-angled triangle without an undercut, wherein the right angle is then arranged in the direction of the rear end of the slide.In a preferred embodiment, the tooth region is arranged in a region projecting from the lower surface. As a result, the slide comprises a shoulder between the lower surface and the toothed region, so that the slide rests on the lower surface and can be pushed in the sliding direction until it abuts the shoulder. By appropriate dimensioning of the protruding region, it is possible to prevent a (too large) force from acting on the tooth region or the teeth.In a further preferred embodiment, the slide has a first abutment at the front end, which abutment runs perpendicular to the upper surface, wherein the first abutment corresponds in particular to a front surface of the slide. Additionally or alternatively, the slider has a second abutment in the region of the rear end, which abutment protrudes perpendicularly from the upper surface. A thrust defines a stop in the sliding direction, i.e. the slide can only be slid in a predefined range in the sliding direction. This allows simple handling of the slide and prevents, in particular, misalignment.In a further preferred embodiment, the slider comprises a rail, wherein the rail is arranged on the lower surface of the slider and wherein a lower surface of the rail runs parallel to the lower surface of the slider. In particular, the rail protrudes perpendicularly from the lower surface of the slide. Furthermore, the rail is preferably arranged centrally between the two side surfaces of the slide. Additionally or alternatively, the rail is shorter in a sliding direction of the slide than the lower surface of the slide, i.e. in particular at the front end of the slide, the lower surface of the slide protrudes beyond the rail in the sliding direction. Preferably, one rail is provided, wherein alternatively two or more rails can also be provided. The rail allows the slider to be guided under the fan during the sliding operation.In a further preferred embodiment, the slide has an actuating element at the rear end, wherein the actuating element has an upper lever element and a lower lever element, wherein the upper lever element is arranged above the recess and the lower lever element is arranged below the recess. In particular, the slide has an upper region and a lower region, wherein the upper lever element is arranged on the upper region of the slide and the lower lever element is arranged on the lower region of the slide. This makes it possible to exert force or press together the upper region and the lower region of the slide, for example in order to release the teeth from a corresponding toothing rail, and thus to simplify removal of the slide from the ventilation device.In a further preferred embodiment, the upper surface has a slope at the front end, which slope is sloped toward the lower surface in the sliding direction. This simplifies insertion of the slider under the fan.It has been found that a preferred angle formed by the inclination of the lower surface to the upper surface, i.e. an angle between the respective planes, is between 6° and 10°. Particularly preferred is an angle between the upper surface and the lower surface of 8°.The invention also relates to a system having two slides, each of which is designed according to one of the embodiments mentioned, and a condensate tank. The condensate trough preferably corresponds to a rectangular trough which runs centrally downward and has an opening in the middle, so that condensate liquid can run off.A conventional condensate trough is usually arranged in a region below a heat exchanger in the ventilation device in order to allow possible condensate liquid which arises in the heat exchanger to drain off. Here, the condensate trough is additionally or alternatively arranged below the fan.In the system according to the invention, the condensate tank has two guide regions which are arranged on two opposite sides of the tank and are each designed to receive a slide. In particular, each of the guide regions has a guide track and a toothed rail, wherein the guide track is each configured to receive at least part of the slider and wherein the toothed rail is each configured to be complementary to the toothed region, wherein the slider is each configured to be slid into the respective guide track in a sliding direction, such that the respective toothed region meshes with the respective toothed rail.Alternatively to a condensate trough having two guide regions, two guide regions independent of the condensate trough can also be provided, which then has the above configuration for guiding and locking the slide in the ventilation device.If the condensate trough is thus described in the present case with respect to the two guide regions, alternatively two guide regions independent of the condensate trough can also be provided.In an advantageous embodiment, an upper surface of the guide regions runs parallel to the lower surface of the slide at least in a region of the guide track and in a region of the toothed rail in a pushed-together state of the slide and of the condensate tray. The guide track preferably has in each case at least one guide trough complementary to a guide rail of the slide, wherein then preferably the upper surface of the guide region and a surface in the guide trough runs parallel to the lower surface of the slide in a pushed-together state of the slide and of the condensate trough.The toothed rail is preferably arranged lowered with respect to an upper surface of the guide region, i.e. the toothed rail is arranged in a toothed rail depression in the guide region. If a guide depression is provided, the rack depression is formed deeper than the guide depression, i.e. a surface of the rack depression is preferably provided below the surface of the guide depression. In particular, a surface of the rack trough, a surface of the guide trough and the upper surface of the guide region are preferably arranged parallel to the lower surface of the slide in a collapsed state of the slide and of the condensate trough.Furthermore, the system preferably has a fan, wherein the fan has a fan housing and is arranged above the system, i.e. the slide and the condensate tray. Preferably, a seal to a further component of the ventilation device, for example to a separating part, is arranged on the fan housing, wherein the seal between the fan housing and the further component is compressed by pushing the slide in the pushing direction. The further component is arranged in particular above the fan, i.e. the fan is arranged between the slide and the further component and the slide is arranged between the condensate trough, or the guide regions, and the fan.The invention also relates to a ventilation device having a slide, a condensate trough, or the guide regions, a fan and a further component, which preferably forms at least one transition to an air duct.In particular, the ventilation device comprises at least one, preferably two, slide according to one of the mentioned embodiments and a condensate trough according to one of the mentioned embodiments. In addition, the ventilation device comprises at least one fan, wherein the fan has a fan housing and is arranged above the condensate trough. Furthermore, the ventilation device comprises a further component which forms at least one transition to an air duct and is arranged above the fan, wherein a seal is arranged between the fan housing and / or the further component and wherein the seal is compressed between the fan housing and the further component by pushing the slide in the direction of pushing. The ventilation device preferably also comprises further components, such as a heat exchanger, a further fan, etc.The invention also relates to a condensate trough, wherein the condensate trough has a trough with an outflow opening, wherein the condensate trough has two guide regions each having a guide track and a toothed rail which are arranged on two opposite sides of the trough, wherein the guide track is each configured to receive at least part of a slide according to one of the aforementioned embodiments, and wherein the toothed rail is each configured to be complementary to a toothed region of the slide, in particular to teeth of the slide, wherein the condensate trough is configured to receive a slide in the respective guide track, such that the respective toothed region of the slide meshes with the respective toothed rail of the condensate trough.Features of advantageous embodiments of the invention are defined in particular in the dependent claims, wherein further advantageous features, embodiments and configurations can also be taken from the above explanation and the following discussion for the person skilled in the art.The present invention is illustrated and explained in greater detail below with reference to exemplary embodiments shown in the figures.

A bottom surface 181 of the rail 180 is parallel to the bottom surface 140 of the slider 100. The rail 180 extends perpendicularly from the lower surface 140 of the slider 100 and is centrally located between two side surfaces of the slider 100.

Specifically, the slope 131 extends toward the lower surface 140 in the sliding direction.The angle between the upper surface 130 and the lower surface 140 is preferably between 6° and 10°, particularly preferably 8°.FIG. 2 ashows a perspective illustration for illustrating an exemplary embodiment of the condensate trough according to the invention, FIG. 2 bshows a schematic illustration for illustrating the exemplary embodiment of the condensate trough from FIG. 2 afrom the side.The condensate tray 200 has two guide regions 230, wherein each of the two guide regions 230 has a guide track 210 and a toothed rail 220. In particular, the condensate tray 200 has a rectangular tray 240, wherein the two guide regions 230 are arranged next to the rectangular tray 240 on two opposite sides of the tray 240.The guide track 210 is each configured to receive at least a portion of the slider 100.

In particular, the guide trough has a surface 211 and the toothed rail trough has a surface 221, wherein the surface 211 of the guide trough and the surface 221 of the toothed rail trough in the embodiment shown run parallel to the upper surface 231 of the guide regions, i.e. the surface 211 of the guide trough and the surface 221 of the toothed rail trough are also parallel to the lower surface 140 of the slider 100 in the installed state.In particular, the surface 211 of the guide trough is arranged below the upper surface 231 of the guide regions 230. Further, the surface 221 of the rack trough is disposed below the surface 211 of the guide trough. As a result, a stop 250 is provided between the toothed rail 220 and the guide band 210, against which stop, for example, a protruding region 141 of the slide 100 can abut.FIG. 3 shows a schematic illustration for illustrating an exemplary embodiment of a lower insulation 300 of a ventilation device. The lower insulation 300 is disposed in the ventilator below the condensate pan 200 and corresponds to a part of an entire insulation of the ventilator. In particular, the lower insulation 300 is integrally formed on the condensate tank 200, i.e. a profile of the lower insulation 300 corresponds to a lower profile of the condensate tank 200. Accordingly, the lower insulation 300 has a depression for the guide trough and for the rack trough, i.e. for the two guide regions 230, in particular the guide belts 210 and the racks 220.FIG. 4 shows a schematic illustration for illustrating an exemplary embodiment of a further component 400 of the ventilation device.

Here too, the configuration of the slides 100, the condensate trough 200, the lower insulation 300, the fan 500 or the fan housing 510, and the further component 400 can be seen in order to achieve compression of the seal 412 in the embodiment shown.Although various aspects or features of the invention are shown in combination in the figures, it will be apparent to the person skilled in the art-unless otherwise stated-that the combinations shown and discussed are not the only possible. In particular, mutually corresponding units or feature complexes from different exemplary embodiments can be interchanged with one another.Further considerations will follow with respect to the invention:The invention relates to a fixing of a spiral housing of a ventilation device by means of a snap-in slider. The spiral housing corresponds to a fan housing which comprises a fan. The fan housing preferably comprises plastic or consists entirely of plastic. Preferably, the fan housing is produced by an injection molding process.For the fastening of the spiral housing in the fan device, according to the invention, a slide is used, which likewise preferably consists of a plastic. In a preferred embodiment, the slide has four teeth which can wedge into a toothed rail. Preferably, two toothed rails (for two slides) are provided, which are further preferably located at one or two points of a condensate trough. The condensate tank is in turn preferably joined to an insulation component which is manufactured from EPS, for example.In order that the spiral housing can be mounted in a process-safe manner, a collar is preferably provided on an adjoining component at the air outlet of the spiral housing. The air outlet region of the spiral housing is inserted into this collar, that is to say the slide "presses" the spiral housing or the air outlet region of the spiral housing into an opening of the adjacent component which is surrounded by the collar.In a preferred embodiment of the slider, the slider comprises an upper surface and a lower surface, each defining a plane which differs as follows: the upper surface, when installed, defines a horizontal plane, the lower surface defines a plane which is oblique to the horizontal plane. The inclined lower surface has the function that the slide increases in height during a transverse movement of the slide. The horizontal upper surface has the task that the slide moves exclusively vertically upward. In particular, the slide has a wedge-shaped configuration.For fastening the slide in the ventilation device, a lower insulation, for example the EPS, is preferably beveled in a region in which the slide (or the condensate trough) is placed. In the bevel of the insulation, a depression corresponding to a guide region is then let in. The guide region and / or the corresponding trough ensures that the slide is always located at the same location in the corresponding axial direction. It can thus be ensured that the force transmission from the spiral housing via the slide, via the guide region, i.e. optionally via the condensate trough, into the insulation, i.e. the EPS, is always in the same region, whereby the corresponding region can be designed structurally.Since the insulation, i.e. the EPS, often has a sensitive surface and the fan has to be removed frequently in its life cycle for maintenance purposes, in this case the surface of the insulation, i.e. the EPS, would be damaged in the fastening region. This is particularly true of the toothed rail, since a greater load acts on the latter.For this reason, a guide region is provided, wherein the condensate trough is preferably equipped with an additional function of the guide region in the region of the fan fastening, i.e. the slide. In the region of the fan fastening, i.e. the guide region, the condensate trough then preferably has a guide track for positioning the slide. In addition, the condensate trough has a toothed rail which corresponds to a tooth pitch corresponding to the teeth of the slide. By the tooth pitch of the slide / toothed rail it is possible to fasten the slide or with the slide the spiral housing at different heights. This advantage can be used to compensate for tolerances which arise both in the production process of the plastic components and in the assembly process of the individual parts, and relaxations of the plastic over time. In addition, the surface of the condensate tank offers the advantage that the surface of the condensate tank in the fastening region is not worn away or is not worn away as much as that of the insulation. In the case that the slide and the condensate trough are made of plastic, i.e. there is a material pairing of plastic and plastic, the frictional / sliding friction during assembly is moreover significantly reduced in comparison with the exemplary material pairing of EPS plastic. Therefore, the slide valve can be slid on the condensate pan more easily.Preferably, the inclination of the slide or the inclination of the insulation, i.e. of the EPS, and / or the inclination of the condensate trough is 8°. This angle allows a certain stroke per tooth advanced in the transverse direction. This reasonably selected stroke results from an arithmetic and statistical tolerance calculation, in particular with regard to the materials used, e.g. the plastic components used and affected.In a preferred embodiment, the slide has a rail. The slide can be placed by the rail in a process-safe manner, in particular in a guide track of the condensate trough / insulation, in order to be able to influence / control the introduction of force into the condensate trough and / or insulation.More preferably, the slider has a small slope integrated forward on the upper surface. This inclination ensures that the slide can be pushed more easily under the spiral housing.In the rear region of the slide there are the teeth. These teeth engage in the toothed rail or toothed rack and prevent, in particular by the undercut of the teeth, the slide from becoming loose in its position.Additionally or alternatively, the slider comprises a type of "clip function", i.e. the actuating element, wherein an upper part and a lower part of the slider can be compressed. For this purpose, the slide can have a shoulder, i.e. a lever element, on the upper part and / or on the lower part, which facilitates compression for release. By pressing together, the teeth of the slide disengage from the toothed rail / toothed rack and the slide can be removed. This then also releases the fastening of the fan housing.Preferably, in the collar of the further component, which is located above the air outlet of the spiral housing, a seal is provided, which is preferably glued in. The seal ensures that no air can enter / and / or leave between the air outlet of the spiral housing and the following air duct. This seal can be compressed accordingly via the position of the slide.If, for example, relaxation of the plastics occurs over time, the slide could compensate for this relaxation by adjusting it.In a preferred embodiment of the slide, the slide has a stop, wherein a maximum compression is achieved when the stop of the slide reaches the housing front wall. At the same time, the spiral housing then presses against the further component located above, so that the seal is compressed accordingly.Additionally or alternatively, the slider has a further stop on the upper surface of the slider. Furthermore, additionally or alternatively, stops can be provided between the condensate trough and the spiral housing, which stops ensure in particular that the spiral housing is always perpendicular to the separating part, regardless of how far the slide is inserted. In particular, if no collar is provided on the further component, the further stop can be helpful for positioning the fan.
