METHOD FOR MOUNTING A REFRIGERATOR, REFRIGERATOR AND SIDE PANEL ELEMENT

The invention relates to a method for mounting a refrigeration device, in which a machine room of the refrigeration device is partially covered by a side wall element. Furthermore, the invention relates to a refrigeration device with a machine room and a housing, wherein on the housing a partially the engine room lining side wall element is attached, and such a side wall element. Refrigeration appliances, in particular designed as household appliances refrigerators are known and are used to housekeeping in households or in the catering sector to store perishable food and / or drinks at certain temperatures. From DE 10 2010 045 A1 a refrigerator is known which has a machine room in which components of the refrigerant circuit, such as e.g. a compressor are arranged. The machine room is covered during assembly of two side wall elements. To facilitate assembly, the side wall elements on insertion bevels, which must be manually sealed after installation, but before foaming the refrigeration unit body by inserting additional elements.

It is therefore the object underlying the invention to provide a method for mounting a refrigeration device, a refrigeration device and a side wall element, can be dispensed with in such additional elements.

This object is achieved by the method and the objects having the features of the independent claims. Advantageous developments are the subject of the dependent claims.

The present invention is based on the recognition that a special simple assembly without such additional elements is made possible by the fact that the Joining movement for assembling the side wall element with the housing of the refrigerator is divided into two components of different directions.

According to a first aspect, the object according to the invention is achieved by a method in which the side wall element is displaced in a first direction and subsequently in a second direction different from the first direction. As a result, the technical advantage is achieved that an integrally formed on the side wall element sealing member can be brought into a position in which it seals the refrigerator body without manual assembly of an additional element foam tight. This simplifies assembly.

In an advantageous embodiment, the method has the steps:

Engaging a sealing element of the side wall element designed as a stop with a fold of the housing of the refrigeration device,

Displacing the sidewall member in the first direction until the displacement in the first direction is stopped by the sealing member, and displacing the sidewall member in the second direction until the sidewall member has reached its end-wall foam-tightly interconnecting the sidewall member to the housing.

This achieves the technical advantage that the two-part displacement of the side wall element first brings the sealing element into engagement with the fold of the housing of the refrigerator by displacing in the first direction, and then, after stopping this displacement, displacing the side wall element by displacing it into the second Direction is brought to its final position. By engaging in the fold, the sealing element seals the seam foam-tight.

A refrigeration device is understood in particular to be a household appliance, that is to say a refrigeration device that is used for household purposes in households or in the gastronomy sector, and in particular for serving food and / or drinks to store certain temperatures, such as. A refrigerator, a freezer, a fridge freezer, a freezer or a wine fridge.

In a further advantageous embodiment, the side wall element has a pin which is brought into engagement with the fold during the engagement of the sealing element with the fold. This achieves the technical advantage that the sidewall element additionally stabilizes during the displacement in the first direction and thus, for example, in the first direction. An unwanted tilting is reliably prevented. In a further advantageous embodiment, the sealing element is displaced in the first direction by a linear movement. As a result, the technical advantage is achieved that the assembly is particularly easy to perform.

In a further advantageous embodiment, the sealing element is displaced in the second direction by a pivoting movement. As a result, the technical advantage is achieved that no additional guidance for the second direction is necessary. Thus, a side wall element can be used with a particularly simple structure.

In a further advantageous embodiment, the axis of the first direction and the axis of the second direction coincide. As a result, the technical advantage is achieved that the assembly is simplified again.

In a further advantageous embodiment, a contact surface of the sealing member slides on a mating contact surface of the housing during the displacement in the second direction. Thereby, the technical advantage is achieved that the side wall element additionally guided during the displacement in the second direction and thus, e.g. An unwanted tilting is reliably prevented.

In a further advantageous embodiment, the side wall element is locked in its end position with the housing. As a result, the technical advantage is achieved that the side wall element is secured in its final position. By locking a backup in the final position without fasteners such as screws or rivets is possible, which simplifies installation. According to a second aspect, the object of the invention is achieved by a refrigeration device with a machine room and a housing, wherein on the housing a partially the engine room lining side wall element is attached, wherein the side wall element is foam-tight manner with the housing by positive engagement. As a result, the technical advantage is achieved that at the same time a seal by forming the positive connection, so that no additional elements are more necessary.

In an advantageous embodiment, a contact surface of the side wall element is in contact with a mating contact surface of the housing. As a result, the technical advantage is achieved that the displacement in the first direction is stopped by the contact of the two surfaces. This simplifies assembly.

In a further advantageous embodiment, the sealing element engages in a fold of the housing. As a result, the technical advantage is achieved that the sealing element seals the fold, so that no additional elements are necessary.

In a further advantageous embodiment, the stop is in contact with a counter-stop of the housing. As a result, the technical advantage is achieved that the position of the side wall element is clearly defined.

In a further advantageous embodiment, the side wall element has a pin which engages in the fold. As a result, the technical advantage is achieved that the position of the side wall element in the direction of another axis is clearly defined.

In a further advantageous embodiment, the side wall element has a latching hook, which dips into a latching recess of the housing. Thereby, the technical advantage is achieved that a fuse in the final position without fasteners, such. Screws or rivets, is possible, which simplifies assembly.

According to a third aspect, the object of the invention is achieved by a side wall element for partially covering a machine room of a refrigerator, wherein the side wall element for attachment to a housing of the Refrigeration device is formed, wherein the side wall element is formed to form a foam-tight positive connection with the housing. As a result, the technical advantage is achieved that at the same time a seal by forming the positive connection, so that no additional elements are more necessary.

5 is a detailed view of Fig. 4th

Fig. 1 shows a refrigerator as an exemplary embodiment of a refrigeration device 100 with a machine room 102. The refrigerator is used, for example. For cooling food and includes a refrigerant circuit with an evaporator (not shown), a compressor 104, a condenser (not shown) and a Throttle body (not shown). The compressor 104 is attached to a mounting rail 108 in the engine room 102.

The evaporator is designed as a heat exchanger in which, after expansion, the liquid refrigerant is vaporized by absorbing heat from the medium to be cooled, ie air inside the refrigerator. The compressor 104 is a mechanically driven component that draws refrigerant vapor from the evaporator and expels at a higher pressure to the condenser.

The condenser is designed as a heat exchanger in which, after compression, the evaporated refrigerant is released by heat to an external cooling medium, i. the ambient air is liquefied.

The throttle body is a device for the continuous reduction of the pressure by reduction in cross section.

The refrigerant is a fluid used for heat transfer in the cryogenic system which absorbs heat at low temperatures and low pressure of the fluid and releases heat at higher temperature and higher pressure of the fluid, usually including changes in state of the fluid.

The machine room 102 is covered on both sides by side wall elements 106, which are made of plastic in the present embodiment by injection molding.

FIG. 2 shows that the side wall element 106 has a sealing element 204. In the present exemplary embodiment, the sealing element 204 is formed in one piece with the side wall element 106 in the same material as the material. Furthermore, the sealing element 204 on three pins 206, which are also formed in the present embodiment in one piece and of the same material with the side wall member 106. Finally, the side wall element 106 has two latching hooks 208.

The sealing element 204 and the pins 206 are configured to engage in a rebate 202, which is associated with a housing 200 of the refrigeration device 100. The housing 200 is formed in the present embodiment by a first bent sheet metal rail 210 with the fold 202 and by a second bent sheet metal rail 212. The sheet metal rails 210, 212 extend at portions of the outer edge of the machine room 102.

Since the illustration of FIG. 2 is rotated counterclockwise by 90 ° in comparison to the illustration of FIG. 1, the first sheet metal rail 210 extends with the fold 202 in the direction of their longitudinal extension in refrigerator depth direction X, while the second sheet metal rail 212 extends with its longitudinal extension in the direction of the refrigeration device U-direction Z. The two latching hooks 208 are designed to immerse in the latching recess 214 of the second sheet metal rail 212 of the housing 200.

For mounting the side wall member 106, the side wall member 106 is placed over the housing 200 in the initial position in a first step.

In a further step, the side wall element 106 is lowered onto the housing 200 in the direction of the refrigeration device width direction Y, such that both the sealing element 204 and the pins 206 engage in the fold 202. Subsequently, in a further step, the side wall member 106 is displaced by a linear movement in a first direction I, which extends in refrigerator depth direction X, until the intermediate position shown in Fig. 3 is reached. Here, the sealing member 204 and the pins 206 form by their engagement in the fold 202 a guide which guides the side wall member 106 during this displacement.

In the position shown in Fig. 3, the sealing member 204 abuts with its contact surface 300 on a mating contact surface 302 of the second sheet metal rail 212 of the housing 200. By this contact of the contact surface 300 with the mating contact surface 302 further displacement of the side wall member 106 is prevented or this displacement movement stopped.

In a further step, the side wall element 106 is then displaced in a second direction II. In this case, the side wall element 106 is pivoted. The pivotal movement thereby causes rotation of the side wall member 106 about an axis A identical to the axis along which the side wall member 106 has been displaced in the first direction I. That is, the two axes coincide, so that the pivoting movement takes place about an axis which extends in the direction of the longitudinal extension of the first sheet metal rail 210. Here, the mating contact surface 302 now serves as a sliding surface on which the contact surface 300 slides during the displacement in the second direction II and thus forms a guide during this displacement of the side wall member 106. By displacing the side wall element 106 in the second direction II, the end position for the side wall element 106 shown in FIG. 4 is achieved. In this end position, the latching hooks 208 of the side wall element 106 dip into the latching recesses 214 of the second sheet metal rail 212 and thus fix the side wall element 106 in its end position on the first sheet rail 210 and the second sheet rail 212.

5 shows that in the end position both the sealing element 204 and the pins 206 form a positive connection with the fold 202 and seal them in a foam-tight manner. Thus, in a subsequent foaming of a refrigerator body no foam through the positive connection between the fold 202 and the sealing member 204 and the fold 202 and the pin 206 penetrate.

In summary, during assembly, the sealing member 204 first assumes the guiding function during the displacement of the side wall member 106 in the first direction I, then the function of a sliding surface during the displacement of the side wall member 106 in the second direction II, and finally a sealing function upon reaching the end position of the side wall member 106, in which the sealing member 204, the fold 202 foam-tight seals.
