Definitions

• the present invention relates to a refrigerator with an air duct.
• an air duct may be formed, which is raised against a wall. This embodiment takes up a space in the interior of the refrigeration compartment and causes volume or design problems. An integration of the air duct into a complete one
• Back cover is complex and involves even greater volume loss.
• the object is achieved by a refrigeration device with an air duct, in which the air duct is formed by a recess with wedge-shaped side sections in a wall and a cover attached to the wedge-shaped side sections whose outer surface is flush with the wall.
• the technical advantage is achieved, for example, that the air duct can be flush-mounted in a wall, such as a refrigerator rear wall, integrated and creates a edge-free surface inside the refrigerator. In addition, this increases the available volume inside the refrigerator.
• a refrigeration device is in particular a household refrigeration appliance understood, ie a
• Refrigeration appliance which is used for housekeeping in households or in the catering sector, and in particular serves food and / or drinks at certain
• Store temperatures such as a refrigerator, a freezer, a fridge freezer, a freezer or a wine fridge.
• the depression is a deep-drawn depression in a plastic plate which forms the wall.
• the technical advantage is achieved that the depression in the wall can be formed in a simple manner.
• the wedge-shaped side section comprises a latching means for latching the cover.
• the latching means is a
• the refrigeration device comprises the
• the cover comprises at least one angled edge section at an acute angle for attachment to the wedge-shaped side sections.
• the edge portion comprises a groove for inserting a bulge in the side portion.
• the technical advantage achieved that the cover along the entire air duct can be attached.
• the groove has a U-shaped or a V-shaped cross section.
• the edge portion of the cover is positively in the side portions of the recess.
• the technical advantage achieved that a tight connection between the cover and the wall can be formed.
• the cover is a plastic molded part.
• the cover covers the recess edge-free.
• the recess between the side sections comprises a tub section for enlarging the

• Fig. 1 shows a refrigerator representative of a refrigerator 100 with an upper
• the refrigerator is used for example for Refrigeration of food and includes a refrigerant circuit with an evaporator, a compressor, a condenser and a throttle body.
• the evaporator is a heat exchanger in which after expansion, the liquid refrigerant through
• the compressor is a mechanically operated component, the refrigerant vapor from the
• Evaporator sucks and ejects at a higher pressure to the condenser.
• Condenser is a heat exchanger in which, after compression, the vaporized refrigerant is released by heat release 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 cross-sectional constriction.
• 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 pressure of the fluid, usually including changes in state of the fluid.
• the refrigeration device 100 comprises an upper and a lower refrigerator door 103, each of which can close a refrigeration compartment inside the refrigeration device 100 and be opened by a user.
• an air duct may be formed by means of an air duct, through which, for example, cold air on a rear wall
• Fig. 2 shows a view of an air duct 101 for air guidance.
• the air channel 101 is defined by a recess 103 with wedge-shaped side portions 105 in a wall 107 of the
• Refrigerating appliance 100 formed along the dashed lines.
• the air channel 101 is formed by a latched on the wedge-shaped side portions 105 cover 109.
• the side portions 105 extend opposite the wall 107 in one
• the locking means 1 1 1 is formed by bulge portions 123 in the wedge-shaped
• the bulge portions 123 are v-shaped in cross section.
• a leg of the v-shape of the bulge portions 123 forms a surface portion 1 13, which is parallel to Wall 107 runs.
• the other leg of the v-shape of the bulge portions 123 continues the depression 103 to the rear.
• the cover 109 has two acute angled edge portions 1 17 to
• edge sections 1 17 of the cover in each case a groove 1 19 is formed, in which the respective bulge portion 123 is inserted.
• the grooves 1 19 also have a V-shaped cross section, so that a positive connection with the profile of the side portions 105 is achieved.
• the edge portion 1 17 of the cover 109 is therefore positively in the

• the depression 103 is, for example, a deep-drawn depression in a plastic plate which forms the wall 107.
• the outside of the cover extends substantially flush with the wall 107.
• a flush integration of the air duct in the rear wall of the refrigeration device 100 can be achieved.
• Such a configuration of the air duct 101 fulfills various technical requirements that exist due to certain circumstances with regard to an insulation, drawing and foaming technique, icing, a refrigeration technique, an air flow rate and an injection molding technique.
• a trough section 121 is formed as a further depression, which extends in the flow direction of the air channel 101 and widened the recess 103 to the rear.
• the trough portion 121 thus serves to enlarge the
• the recess is covered in the rear wall. This results in a nearly flush and integrative design.
