Description

The invention relates to a household appliance, in particular household refrigeration appliance, comprising a body extending from a front side to a rear side in the depth direction with at least two receptacles for the arrangement of a wall spacer.

Domestic appliances, especially domestic refrigerators, can generate heat during operation, which must be dissipated as well as possible for reliable and efficient operation. For example, a condenser arranged on the rear side of a household refrigerating appliance and / or an engine room of a household refrigerating appliance open to the rear generate waste heat. Inadequate dissipation of this waste heat can be done on the one hand caused by overheating damage to the household refrigerator and on the other hand, the efficiency of the household refrigerator can be reduced. The problem of insufficient discharge of waste heat occurs in particular when the household appliance is set up with its rear wall too close to a wall.

A known measure for improving the discharge of such waste heat provides to equip the household appliance with at least one wall spacer, which extends from the back in a direction away from the housing. Such wall spacers thus prevent the household appliance can be positioned with its back directly to a wall and thus cause a minimum distance between the back and the wall.

From the EP 2 455 692 A2 is a household refrigerator with a rear wall arranged condenser and spacer known in which the spacer can be pivoted between a first position and a second position. In the first position, the spacer causes the EP 2 455 692 A2 in that a distance is created between the condenser and a wall facing the rear wall, while the spacer in the second position does not protrude beyond the condenser. The Indian EP 2 455 692 A2 shown constructive structure, comprising a pivoting mechanism is complicated, allows only two different positions of the wall spacer and can be pivoted when inadvertently, if necessary, from one position to the other position.

From the KR 2010 0008602 a spacer for a refrigerator is known, which can be hung on a rear wall of the refrigerator by means of brackets in a corresponding holder, so that a certain, predetermined distance of the rear wall to a wall on which the refrigerator is to be set up, can be possible. The from the KR 2010 0008602 Known spacer can only set a fixed distance of the rear wall to a wall.

The object of the present invention is to develop a generic household appliance and to overcome the disadvantages of the prior art.

This object is achieved according to the invention by providing in a household appliance mentioned in the introduction that the at least two receptacles are designed such that a free end section of a wall spacer has a different position in the depth direction of the household appliance depending on which of the at least two receptacles of the wall spacers is arranged ,

The present invention is based on the recognition that in the household appliance by appropriately trained shots, in an extremely simple manner, the possibility is created to allow two different positions of the free end of the wall spacer by one and the same wall spacer.

However, it is not necessary to equip the household appliance according to the invention always with a corresponding wall spacers. Rather, the wall spacer can be delivered only when needed with the household appliance or mounted only when needed when setting up the appliance on site. In particular, all domestic appliances of a series can thus have at least two receptacles, whereas wall spacers are used at all for certain set-up situations or are supplied with the household appliance. The additional costs for preparing all household appliances of a series for arranging the wall spacer, namely by providing the at least two shots, are minimal.

By combining a single wall spacer with the at least two receptacles, there is also no risk that a wall spacer may be lost, as would be the case with the use of two different wall spacers: depending on the desired position of the wall spacer in the depth direction, This can always be arranged in one of the two shots.

The wall spacer is a separate component from the at least two receptacles.

Preferred embodiments are specified in the subclaims.

According to one embodiment, it is provided that the at least two receptacles have clamping elements and / or stop elements for fixing a position of the wall spacer in the depth direction of the household appliance. While clamping elements cause a non-positive connection between receiving and wall spacers, stop elements can cause a positive connection. Preferably, the clamping elements and / or stop elements are formed integrally with the at least two receptacles. Further preferably, the clamping elements and / or stop elements in a first receptacle of the two receptacles are identical to those of a second receptacle of the two receptacles.

According to a further embodiment, it is provided that the clamping elements and / or stop elements have a different position in the depth direction of the household appliance.

Alternatively or additionally, it can be provided that the clamping elements and / or stop elements have a different angle with respect to the rear side.

A particularly simple and inexpensive to manufacture and simplifying the mounting of the wall spacer embodiment provides that the at least two receptacles are formed by holes, preferably by blind holes with a bottom hole. If blind holes are used, the bottom of the hole can serve as a stop element for determining a position of the wall spacer in the depth direction of the household appliance.

It is preferably provided that the holes or blind holes extend parallel to the depth direction, ie perpendicular to a plane substantially parallel to the rear wall. An inserted in such a bore, e.g. rod-shaped wall spacer takes in this case only longitudinal forces when the household appliance is pushed back against a wall.

Although it is in principle possible to form the at least two receptacles by holes or blind holes, which have an equal depth and to achieve the different position of the free end portion of the wall spacer by a corresponding position of clamping elements and / or stop elements of the recordings. Thus, the at least two recordings could e.g. are formed by parallel and the same depth having holes, but offset in the depth direction to each other. Preferably, however, it is provided according to an embodiment that the at least two receptacles are formed by holes or blind holes of different depths. This allows openings of the at least two receptacles in the depth direction to be positioned at the same height. The at least two shots are thus immediately recognizable for a fitter as such, easily accessible and the installation of the wall spacer is correspondingly simple.

According to one embodiment, it is provided that the bores or blind bores have clamping elements in the form of ribs. Preferably, the ribs are integral with the bores or blind bores, e.g. on inner lateral surfaces.

Although it is provided according to an embodiment that the at least two receptacles each have an opening and that the openings do not overlap. In order to facilitate the recognizability of the recordings as such and thus the assembly, it can however be provided that the openings are located next to one another. In particular, it can be provided that a distance from the center points of the openings is not greater than twice an innkreisdurchmessers of the openings.

In principle, the at least two receptacles can be placed anywhere on the body, e.g. on side walls of the carcass, on a ceiling of the carcass or a floor of the carcass. However, in order to ensure a good introduction of force in the body on the one hand and a simple production on the other hand is provided according to an embodiment that the at least two receptacles are arranged on a side wall and / or on a ceiling strut of a machine room. This exploits that the corresponding components of the engine room already have a high structural strength in principle and thus can serve to arrange the images without further reinforcing measures. A ceiling strut is part of a ceiling of a machine room or forms the ceiling of a machine room. Preferably, openings of the at least two receptacles are open only to the rear of the household appliance.

According to one embodiment, it is provided that the at least two receptacles are formed integrally with the side wall and / or the ceiling strut. In particular, the side wall and / or the top wall can be injection molded components made of plastic, in which the receptacles are already completely formed during the injection molding production.

Preferably, the at least two receptacles are designed such that a wall spacer can be arranged in it without tools by hand. In particular, it is provided according to an embodiment that the at least two receptacles are formed for insertion of the wall spacer. Preferably, the recordings, e.g. in the form of holes or blind holes, a depth direction substantially constant cross section. Alternatively, the cross-section can taper counter to the depth direction in order to ensure a press fit when inserting the wall spacer.

According to one embodiment, it is provided that a wall spacer is arranged in only one of the at least two receptacles. In particular, no wall spacers are arranged in the other of the at least two receptacles.

Although according to the invention, at least two shots are sufficient to solve the task. Preferably, however, it is provided that at least two Pairs of at least two shots are provided to reduce the loads on the wall spacer when contacting a wall by using a separate and separate wall spacer per pair. In particular, a wall spacer is arranged in each of the pairs of the at least two receptacles in only one of the at least two receptacles. In particular, no wall spacer is arranged in the respective other of the at least two receptacles of each pair. In order to enable a secure positioning of the household appliance relative to a wall, the two pairs are preferably arranged at corner regions of the back of the household appliance. Preferably, the two pairs are spaced apart by at least the half width of the household appliance.

The two positions of the free end portion of the wall spacer can either serve to produce two differently sized gaps between a substantially parallel to the back plane and the wall in a pushed against a wall appliance household appliance. Thus, depending on the setup situation and the desired heat dissipation, either a small gap or a large gap could be realized with one and the same wall spacer. Alternatively, however, it may also be desirable that the two positions of the free end portion of the wall spacer on the one hand allow the smallest possible external dimension of the household appliance in the depth direction and on the other hand provide a desired gap between said plane and the wall. For this purpose, according to one embodiment, provision is made for the free end section of the wall spacer, which is arranged in a first receptacle of the at least two receptacles, to protrude in the depth direction over a plane substantially parallel to the rear side and that the free end section of the at least two receptacle in a second receptacle Shooting arranged wall spacer in the depth direction extends to a maximum of the plane. During transport, the wall spacer is thus arranged in the second receptacle and during operation of the household appliance, the wall spacer is arranged in the first receptacle. The plane parallel to the rear wall and adjacent to the rear wall represents a plane enveloping the domestic appliance; For example, a domestic refrigeration appliance can rest on this level with a condenser formed on the rear side.

According to one embodiment, it is provided that the wall spacer is held non-positively and / or positively. A form-fitting support may in particular be formed by a bottom of the receptacle and / or by a stop within the receptacle, e.g. a bore bottom of a recording forming hole. A frictional mounting may in particular by a press fit, i. Undersize fit, be formed between a minimum inner dimension of the receptacle and a corresponding largest outer dimension of the wall spacer, e.g. between an inner circle diameter of a bore forming the receptacle and an outer diameter of a cylinder enveloping the wall spacer. Preferably, a combination of non-positive and positive retention is used: while the positive holder for the position and orientation of the wall spacer and thus ensure the position of its free end portion in the depth direction; the non-positive support, however, can form a captive unit of wall spacers and recording, so that the wall spacer can not fall unintentionally from the recording during transport or when setting up.

A particularly simple and inexpensive to produce household appliance and a simple assembly is achieved if it is provided according to an embodiment that the wall spacer is a rod-shaped component. In particular, the wall spacer may be formed by a cut to a corresponding extent semifinished product. The wall spacer can be, for example, an extrusion component or an injection-molded component.

According to a further embodiment it is provided that the wall spacer has a circular cross-section, a cross-section or a rectangular cross-section. In particular, the wall spacer may be a cylindrical rod of circular cross-section, e.g. made of solid material or as a hollow tube, act.

It is possible that the wall spacer made of plastic or metal.

In Fig. 1 is shown in a perspective view of a household appliance, in the form of a household refrigerator such as a refrigerator, a freezer or a fridge / freezer combination.

The household refrigerator 1 has a body 4 extending from a front side 2 to a rear side 3 in the depth direction y. On the body 4, a door 5 is hinged, with which an unillustrated storage room can be opened and closed.

As the perspective view of the household refrigerator 1 in Fig. 2 Looking at the back 3 shows, two pairs of at least two shots 6, 7 and 8, 9 are present. In each one of the receptacles 6, 7 and 8, 9, a wall spacer, not shown, can be arranged.

In the vertical direction x below an open towards the back 3 engine room 10 is arranged, which serves among other things for receiving a compressor 11. The engine room 10 has for this purpose a bottom 12, a rear wall 13, two side walls, wherein in Fig. 2 a side wall 14 can be seen, as well as a ceiling 15. The floor 12 is preferably a metal and / or plastic component. The side walls 14 are preferably plastic components. The ceiling 15 preferably has a section of cardboard and a preferably made of plastic deck strut 16. Side walls of the household refrigerator 1, for example, the illustrated side wall 17, engage around the side walls 14 of the engine room with flaps 18, 19th

How detailed in Fig. 4 shown on a pair of at least two receptacles 6, 7, each receptacle 6, 7 an opening 20, 21 in order to arrange a wall spacer, not shown, in the receptacles 6, 7 can. The openings 20, 21 are arranged on an outwardly directed in the depth direction y outer surface 22 of the deck strut 16 of the engine room 10.

The receptacles 6, 7 are formed by blind holes, thus each have one of the opening 20, 21 opposite hole bottom 23, 24. The blind holes are arranged parallel to each other and parallel to the depth direction y.

Along the longitudinal extent of the blind holes, ie parallel to the depth direction y, each blind hole has a plurality of, in this embodiment exactly three, arranged on an inner circumferential surface of the blind holes bores 25, 26.

The blind bores are integral with the deck strut 16, e.g. by means of an injection molding process. The blind holes are in pockets 27, 28 introduced.

Fig. 5 shows a section of a schematic plan view of a sectional view Fig. 4 in which the different depths 29, 30 - which can be measured along the depth direction y in this exemplary embodiment - are recognizable. Both openings 20, 21 are at the same height with respect to the depth direction y. Neither the openings 20, 21 nor the receptacles 6, 7 themselves intersect or intersect. Rather, each receptacle 6, 7 is independent and could be arranged independently of the respective other receptacle 6, 7 at an arbitrary position on the body 4.

Fig. 6 shows a comparable representation Fig. 5 , but with inserted, not cut shown Wandabstandshalter 31. For illustrative purposes 6, 7 wall spacers 31 are used in both shots, even if according to the invention only in one of the receptacles 6, 7, a wall spacer 31 is to be used.

The wall spacer 31 is connected by a piece of pipe, e.g. made of plastic.

The arranged in a receptacle 6, 7 wall spacer 31 has on the one hand a held end portion 35 and on the other hand, a free end portion 37. The held end portion 35 contacts a hole base 23, 24 serving as a stopper member, so that a position of the entire wall spacer 31 in the depth direction y is set. The free end portion 37 protrudes from the receptacle 6, 7 in the depth direction y and serves as a stop against a wall to which the household refrigerator 1 is placed.

Depending on in which of the at least two receivers 6, 7 of the wall spacer 31 is arranged, the free end portion 37 of the wall spacer 31 has a different position in the depth direction y. In particular, the free end section 37 extends in the depth direction y at different distances from the front side 2 of the body 4.

The arranged in a first receptacle 6 wall spacer 31 projects beyond the opening 20 with a distance 33 which is different from a distance 34, with which a arranged in a second receptacle 7 wall spacer 31 projects beyond the opening 21.

Also in Fig. 6 a plane 39 is shown which is essentially parallel to the rear side 3 and to the rear side 3. This plane 39 represents a plane enclosing the body 4 without wall spacers in the depth direction y and adjoins, for example, a rear-side condenser. Without wall spacers, the household refrigerator 1 could be pushed up to this level 39 to a wall.

By an appropriate combination of the depths 29, 30 of the blind holes and the extension of the wall spacer 31 in the depth direction y, it is possible that the free end portion 37 of a arranged in the first receptacle 6 wall spacer 31 in the depth direction y behind the plane 39 and one in the second receptacle 7 arranged wall spacer 31 in front of the plane 39 is located. This allows the wall spacer 31 during transport in the second Recording 7 and during operation of the household refrigerator 1 in the first receptacle 6 are arranged.

Of course, it would also be possible for the free end section 37 of both a wall spacer 31 arranged in the first receptacle 6 and in the second receptacle 7 to project beyond a plane 32 in the depth direction y substantially parallel to the back 3 and to the back 3. In this case, the household refrigerator 1 could be positioned at two different distances from a wall.

Fig. 7 shows a detail of a perspective view of a household refrigerator 1 according to a second embodiment. In contrast to the first embodiment of the Fig. 1 to 6 Are now a pair of at least two receptacles 41, 42 arranged on a side wall 40 and a pair of at least two receptacles on a side wall 47 of the machine room 10.

The side walls 40, 47 are injection molded components, in which the receivers 41, 42 are integrally formed.

A side wall 17 of the body 4 surrounds the side wall 40 of the machine room 10 with a fold 19. The openings 43, 44, 45, 46 of the receptacles 41, 42 are behind the fold, which has aligned openings 48.
