Description

The The invention relates to a household refrigerator with at least one receiving space for too cooling Good according to the preamble of claim 1.

It are both built-in cooling and / or freezers as well as stand alone refrigerators and / or freezers, the here all are summarized under the term domestic refrigeration appliance, known with one or more receiving spaces for good to be cooled. For such Recording rooms can ever Upon request, different operating temperatures up to a freezing of the goods to be stored therein. The recording rooms have often for one efficient and affordable Series production comparatively thin walls, which in one Deep drawing process are made out of a flat semi-finished product. Nice As a result, the material thickness of the walls is limited. Their strengths amount typically about 0.6 to 2.5 millimeters. Nevertheless, in breakthrough structures These walls are supported by holding parts in turn, in the interior, for example, shelves or similar, even with heavy goods to be loaded subdivisions are or as brackets for one Temperature sensor, a thermostat, lighting, parts of a control or similar serve. The latter attachments are often also called RLK for controller-lighting combination designated.

It is also known, the holding part on the one hand beyond the edge region of the opening structure engages behind while "back to each other Back "opposite Secure oriented hooks such that thereby a tensile force outward in the direction behind the wall acts, and on the other hand, the holding part via spring force with a force component in the receiving space against the pulling direction force the hook parts to force one way play-free clamping support of the To reach holding parts in the wall.

by virtue of of the thermoforming process in the manufacture of the walls have these but one already over short distances a strongly fluctuating thickness, for example by about a factor 3. So can wall thicknesses from about 0.8 millimeters, from about 2.2 millimeters over a few Centimeters adjacent. It is therefore often difficult or not at all possible, the above a first hook in the opening structure engaging holding part with one opposite Snap latch behind the edge of the wall and thus to secure. The latching hook can not compensate for the tolerances because he defined one with his firm locking projection on one Thickness is optimized. The holding part is then not sufficiently tight used on the wall to achieve a gap-free system to be able to. In such a case, it will often be necessary from the back out as a seal in addition Adhesive tape to be applied during a subsequent foaming in the room outside the walls causes a seal against the receiving space and prevents foam entry into these. Such an assembly aid However, it means a considerable complication and more expensive the production.

Of the The invention is based on the problem in a household cooling device, the support of a holding part to improve in a wall of the receiving space.

The Invention solves this problem by a household refrigerator with the features of the claim 1 and by a holding part for this according to claim 14. With regard to advantageous embodiments and developments the subject matter of the invention is based on the further claims 2 to 13 referenced.

Thereby, that at least two hook parts with respect to each other Extension of the area of the these supporting ones Wall substantially in the same direction oriented rear engagement surfaces for Behind the wall are provided, wherein the rear engagement surfaces in mounted state each one substantially in the same direction oriented component along to the surface the wall and a component substantially perpendicular to this may have both hook parts with respect to their penetration depth against each other vary and thus compensate for different strengths of the walls. Under Walls are not only lateral walls, but also a top, back or underside of the recording room understood. The hook parts can therefore the holding part reliably mechanically hold without any sticking - neither with tape nor with spray glue - or similar more activities would be required.

One Such holding part can then advantageously with an insertion perpendicular and in a direction parallel to the wall in its opening structure are used, preferably so far, to one on the holding part arranged abutment comes to engage in the aperture structure while retreating the holding member blocked against the orientation of the engaging surfaces. Then it's a reliable one Securing against longitudinal displacement reaches the holding part, at the same time by the inclination the Hintergreifflächen also a perpendicular to the respective Einsatzwandung pull-out is reached.

In particular, the at least two hook parts and an advantageous variant of a large distance to each other in the longitudinal direction tion of the holding part and thereby allow a reliable hold of the holding part over its entire extent. It is advantageous if the opening structure of the wall a plurality of insertion openings for the hook parts of the holding part with a Wandungssteg therebetween, which can be engaged behind by a hook part, and also the abutment on these the insertion openings delimiting Wandungssteg is supported.

For a low-power and hook-free assembly can the Hintergreifflächen advantageous as Abgleitschrägen for the Be formed edge region of the opening (s).

A reliable Holding the hook parts can be reach in particular when the sliding slopes extend over at least five millimeters, in particular at least ten millimeters, extend longitudinally to the wall.

If the sliding slopes for a purposeful training the invention over at least five, in particular more than ten millimeters, extend perpendicular to the wall, can so that the o. g. huge Thickness differences are compensated; It is also with large tolerances the thermoforming process is a reliable one Behind the wall in the edge region of the opening structure allows.

Provided the holding part in an advantageous manner with at least one in the direction the receiving space effective spring clip is provided, depending on the wall thickness can be deformed in different degrees of deformation, can high holding force are applied in the direction of the receiving space. Especially can the spring clip be formed circumferentially and simultaneously sealing.

alternative can also be provided a separate circumferential seal, the also advantageous depending on the wall thickness in different degrees of deformation is deformable and thus tolerance compensation for the different wall thickness can form.

For a cheap Production and simple assembly is the or each holding part in particular integrally formed, For example, as a multi-component injection molding, the different elasticities in accommodation to various occurring loads in the course of the component allows. For example, the outer seal in deviation from the body have a rubber elasticity, such as by that they are facing a body of the holding part a reduced material thickness and / or has a different material, and thereby the spring action enable and at the same time the behind the wall insulation area from the recording room over shield the gasket. The one-piece can still be maintained become.

In spite of the rubber elasticity The seal can advantageously made of a thermoplastic material formed and thus injectable to a seal holding body 'of the holding part be. This can be a dimensionally stable subunit of a also form thermoplastic.

The Assembly can also be done manually with just a hand, with in particular the striking of the abutment as confirmation of the correct Seat is also acoustically perceptible.

other Further developments of the invention are given in the dependent claims.

Further Advantages and features of the invention and its developments emerge from the drawing and shown below described embodiments the subject of the invention.

In the drawing shows:

1 a domestic refrigerator in a perspective view from the front and top - without door - with a receiving space, which is provided for example on a left side wall with an opening structure for receiving a holding part, in a schematic view,

2 a drawn out receiving space, the overall deep-drawn and provided on a right side wall with a holding part inserted from the outside, in a perspective view from the inside,

3 a drawn out receiving space, the overall deep-drawn and provided on a right side wall with a holding part inserted from the outside, in a perspective view from the outside,

4 a section through the latched to the wall holding part, approximately along the line IV-IV in 2 .

5 a similar sectional view as 4 but a conventional holding part without a construction according to the invention,

6 the holding part after 4 in perspective view, seen from the recording room,

7 the inserted holding part 4 in side view,

8th the holding part after 4 in plan view, seen from the receiving room,

9 the holding part after 4 in a perspective sectional view in its supported in the opening structure insert position.

Elements with the same function and mode of action are in the 1 with 9 each provided with the same reference numerals.

This in 1 shown household cooling device HK has, for example, exactly one receiving space AR for good to be cooled, even more receiving spaces AR for cooling and / or freezing are possible. These can be closed by one or more door (s) - not shown here.

The receiving space AR is limited to the sides and to the rear and above and below by walls W of a usually deep-drawn plastic part, wherein the walls W of this molding can be provided with through-holes D, as for example in the schematically drawn out receiving space AR after 2 is recognizable. The narrow space between the walls W and an outer housing G of the household refrigerating appliance HK is usually filled with an insulating material, such as a foam, completely or at least for the most part.

In the aperture structures D through the thin walls W (typical wall thicknesses from about 0.6 to 2.5 millimeters) holding parts HT can be used with restraint - for example, as shown here, from the outside - in the mounted state protrude into the receiving space AR and in particular a temperature sensor, hold a bulb and / or a thermostat. Also a support of others Parts, such as shelves, through such holding parts HT is possible.

In a wall W can one - like shown here - or also several perforation structure (s) D be provided.

Of the or each holding part HT engages behind the wall W in the edge region an opening structure D with at least two hook parts H1, H2 here from the outside inside. At the same time, the holding part HT via spring force F with a Force component against the pulling direction of the hook parts H1; H2 powerful, so that a respect a vertical direction to the wall W play-free clamping bracket of the holding part HT is reached.

Like in 4 is clearly visible, at least two hook portions H1, H2 provided with mutually with respect to the extension of the surface of the wall W in the same direction rear engaging surfaces HF for engaging behind the wall W. These Hintergreifflächen HF have in the assembled state each oriented in the same direction component along the surface of the wall W and a component perpendicular to this, which points in the direction of the wall W.

In addition to These hook parts H1, H2 is the holding part HT with an abutment WL, which is so securable in the aperture structure D, that retraction of the holding part HT against the orientation of the rear engagement surfaces HF along the Wall is blocked.

Around this opposite support on the one hand the hook parts H1, H2 and on the other hand of the abutment To enable WL has the opening structure D for the hook parts H1, H2 of the Holding parts HT several insertion openings D1, D2 on, by a delimiting wall web WS from each other are separated. At this is the abutment WL, which by a simple Stage can be formed without engaging latching projection, supportable. In order to is also re a longitudinal direction the wall extension of the holding part HT between the hook parts H1, H2 on the one hand and the abutment WL on the other hand clamped halterbar.

Various Wall thicknesses at the insert openings D1, D2 of the two hook parts H1, H2 can easily with different Insert depth can be compensated when the Hintergreifflächen HF as Abgleitschrägen for the formed to engage behind edge region of the insertion openings D1, D2 are. these can a big Have width of for example more than one centimeter and thereby be stable and have a good handling during assembly.

there can the Abgleitschrägen about at least five millimeters, better ten or fifteen millimeters, along the Wall W extend.

Also perpendicular to the wall W can the sliding slopes over at least five Mm, in particular ten or fifteen millimeters, perpendicular to Wall W extend, so as to compensate for tolerance allow the wall thickness.

One in mounted position at height The wall W lying neck portion of the hook parts H1, H2 can be made thin and thereby provided with a certain elasticity and bendability be.

Despite the changing wall thickness a secure fit is ensured by the fact that the holding part H is provided with at least one in the direction of the wall W effective spring clip F, depending on the wall thickness in different De formation degree is deformable and thereby can compensate for the variations in the wall thickness. This different deformability as compensation for different wall thicknesses is also present on a seal DG of the holding part, which shields the receiving space AR against the insulating material to be introduced in the outer space. The spring clip F can be integral with the holding part HT.

In the top view of the holding part HT can be seen that here the seal DG by the outermost Area of the spring clip F is formed, the one elastic edge of the holding part HT formed. The seal DG rotates in the assembly position, the opening structure D in each case completely. It is the seal DG elastic and depending on the wall thickness in different Deformation deformable, so that with a very thin wall W an outer edge line the seal DG in sealing contact with this would come. at a larger wall thickness, however would the Overall here lip-shaped seal DG pushed away with its edge further outward, so that then, for example, a radially inner line to sealing attachment to the outside the wall W would come. This is in any case a good seal of the receiving space AR when introducing first liquid foam reached in the space between the wall W and housing G.

In spite of the over its course different material properties can the or each holding part HT nevertheless a the assembly and handling very much have simplistic one-piece, by, for example, in a multi-component injection molding (so-called. 2K method).

To its mounting, the holding part HT machine or in particular also manually in the opening structure D of the wall W from the outside or be inserted inside, in particular to simplify the assembly that the operational orientation of a holding part HT in the opening structure D is forcibly specified, for example, by different sized insert openings D1 and D2.

At the Insertion of the holding part HT then passes at a sufficient distance Advancing the hook parts H1, H2 along the wall W automatically also the abutment WL to its stop on the wall web WS. By the sliding surfaces the hook parts H1, H2 is a spring-back force along the Wall W exerted, which presses the abutment WL in its holding position.

One such holding part HT is also claimed separately.
