Description

TECHNICAL FIELD

[0001] The present invention relates to a household appliance, in particular a household refrigeration appliance such as a refrigerator, a freezer or a freezer chest or a fridge-freezer combination. STATE OF THE ART

[0002] Household refrigeration appliances typically have a body that defines a storage compartment with an access opening. Objects such as food or drinks can be placed in or taken out of the storage compartment through the access opening. To close or open the access opening, a door that can be pivoted about a pivot axis is usually attached to the body. The storage compartment usually also has a light that is activated when the door is opened to illuminate the storage compartment. Shelves, for example for bottles, eggs or similar, are often attached to an inner surface of the door. When the door is open, the inner surface of the door is usually illuminated from the surroundings.

[0003] DE 10 2015 003 018 A1 describes a household refrigeration appliance in which vertical ribs are provided on an inner surface of the door, each extending parallel to a rotational axis about which the door pivots. On the outer side of the rib facing the rotational axis, a light arrangement is mounted, which, when the door is in an open position, emits light into the storage compartment. SUMMARY OF THE INVENTION

[0004] It is one of the objects of the present invention to provide improved solutions for the integration of functional elements, such as lighting or sensor elements, into a door of a household appliance.

[0005] This object is achieved according to the invention by a refrigeration device having the features of claim 1.

[0006] A household appliance according to the invention comprises a body defining a storage compartment with an access opening for accommodating items to be tempered, and a door mounted on the body so as to be movable about a pivot axis between a closed position and an open position. The door has an inner surface, which, in the closed position, faces the storage compartment, and a rib protruding from the inner surface and extending transversely to the pivot axis. A functional unit having a lighting and / or a sensor arrangement is attached to the rib.

[0007] One idea underlying the invention is to integrate a lighting device, e.g., for illuminating the interior surface itself, a sensor unit, or another functional unit, into a rib extending transversely to the door's rotation axis. The rib forms a projection that protrudes from the interior surface of the door. The rib can, for example, have a U-shaped cross-section. The sensor arrangement, the lighting device, or the functional unit in general, is fixed to the rib.

[0008] Because the rib protrudes from the inside of the door, it is visible to the user when the door is open. Integrating lighting into the rib can therefore help improve the aesthetic appearance of the door. In addition, the rib creates a space to house the functional components, which are thus integrated into the door in a very space-saving manner. With regard to the accommodation of a sensor arrangement, the rib extending transversely to the axis of rotation is advantageous because it is easily accessible when the door is open, which is useful, for example, for servicing. When the door is closed, the rib extends in a width direction of the storage compartment, which is advantageous with regard to a possible field of view of a sensor in the sensor arrangement.

[0009] Advantageous embodiments and further developments arise from the subclaims which refer back to the independent claims in conjunction with the description.

[0010] According to some embodiments, it can be provided that the household appliance is a household refrigeration appliance, e.g. in the form of a refrigerator, a freezer or a freezer chest or a fridge-freezer combination.

[0011] The household appliance can be an electrically operated household appliance with a processing chamber for processing goods. The household appliance can be a household refrigerator, freezer, or a combination thereof. The processing chamber serves to store goods, particularly goods to be cooled. Furthermore, the household appliance can be a baking oven, cooking oven, or dishwasher. The processing chamber of an oven serves to heat goods, the processing chamber of an oven serves to cook goods, and the processing chamber of a dishwasher serves to wash or clean dishes.

[0012] A "household refrigeration appliance" is specifically understood to be a cabinet-shaped device that is usually electrically operated and independently maintains a low temperature inside the treatment room. The interior of the refrigerator is cooled by a compressor, often located at the rear and controlled by a temperature controller. The refrigeration unit is a refrigeration machine that utilizes the physical effect of latent heat when changing the state of matter from liquid to gaseous. A refrigerant that moves in a closed circuit undergoes various successive changes of state. The gaseous refrigerant is first compressed by a refrigeration unit. It then condenses in the condenser, releasing heat. The liquid refrigerant is then expanded due to the pressure change via a throttle, for example an expansion valve or a capillary tube.In the downstream evaporator, the refrigerant evaporates at a low temperature, absorbing heat. The cycle can now begin again. The process must be kept going from the outside by the supply of mechanical work via the refrigeration unit. The refrigerant absorbs heat at a low temperature level, for example a 5°C cold refrigerator interior or storage compartment, and releases it to the environment by supplying mechanical work at a higher temperature level, for example a 35°C condensing temperature in the condenser on the outside of the refrigerator. Household refrigeration appliances are typically used for the treatment and storage of goods, in particular food. Due to the lower temperature, chemical reactions and biological processes that, for example, render food inedible and medicine unusable, proceed more slowly.The typical operating temperatures inside household refrigeration appliances are between plus 2°C and plus 8°C in cold storage rooms, between minus 14°C and minus 18°C ​​in freezer compartments, and between minus 2°C and plus 4°C in zero-degree compartments. The housing of the refrigeration compartments is thermally insulated to minimize the energy required to maintain the difference from the ambient temperature.

[0013] The treatment chamber can be defined by an inner container made of plastic or metal, which is enclosed by the housing and thermal insulation. The treatment chamber has a front loading or access opening. The treatment chamber can have one or more compartment shelves and possibly also one or more drawer compartments, e.g. for accommodating drawers, for example for special climate zones. The household refrigeration appliance has a door for opening and closing the treatment chamber, which door is pivotally mounted on the housing, for example with respect to a vertical pivot axis, a so-called pivot door. Furthermore, it can be a double-door arrangement in which both doors can be pivoted about a vertical axis and, when viewed from the front of the household appliance, a left-hand door is hinged on a housing of the household refrigeration appliance with its left side, while a right-hand door is hinged on the housing with its right side.The inside of the door, which faces the treatment room when the door is closed, can be set up for storing stored goods, e.g. by means of storage compartments for bottles, butter, eggs, etc.

[0014] According to some embodiments, the rib can extend over an area between 5% and 100% of a width of the door, measured in a direction perpendicular to the axis of rotation. Thus, the rib can be designed as a substantially discrete projection that extends, for example, over only 5% to 15% of the width of the door. Alternatively, the rib can extend substantially over the entire width of the door, for example, over at least 75% of the width, which increases the freedom for positioning one or more functional units. In this case, the rib can also act even better as a barrier for the cold air present in the storage compartment.

[0015] According to some embodiments, the functional unit can extend at least partially along a longitudinal extent of the rib. For example, an elongated lighting unit can be accommodated in the rib in a space-saving manner.

[0016] According to some embodiments, the sensor arrangement may include an optical sensor, in particular an imaging sensor, such as a CMOS sensor. The optical sensor may be, for example, a camera sensor. When the door is closed, the optical sensor faces the storage compartment and, due to the rib's extension transverse to the rotation axis, can cover a large field of view. The field of view can be further enlarged if the sensor is positioned in the region of the center of the rib with respect to its longitudinal extension.

[0017] According to some embodiments, the functional unit may comprise one or more light sources, e.g., in the form of LEDs, which are aligned substantially parallel to the inner surface of the door in order to emit light across the inner surface and illuminate it. Thus, the inner surface can be designed in an aesthetically pleasing manner and additionally illuminated.

[0018] According to some embodiments, it can be provided that the functional unit is detachably connected to the rib. For example, it can be provided that the functional unit is screwed or latched to the rib. For example, latching elements can be formed on the functional unit, which are designed for positive engagement with latching elements on the rib. In particular, it is conceivable for the functional unit to have a housing or a support part, on which latching hooks are formed, which engage in undercuts formed on the rib. The detachable attachment of the functional unit to the rib facilitates the assembly of the functional unit. Furthermore, modular manufacture or production of the door can be facilitated, since different functional units can be easily attached to one and the same door.

[0019] According to some embodiments, the rib can have a recess in which the functional unit is at least partially accommodated. According to some embodiments, the recess can be designed as a depression or trough in an outer surface of the rib. According to further embodiments, the recess can be designed as a through-opening which extends between the outer surface of the rib and an inner surface of the rib defining a receiving space, wherein the functional unit is at least partially arranged within the receiving space. The accommodation of the functional unit in a recess on the rib further reduces the space required by the functional unit on the inner surface of the door.

[0020] According to some embodiments, the door may include an outer lining, an inner lining, and insulation disposed between the inner lining and the outer lining. The inner lining comprises the inner surface of the door and, when the door is closed, faces the storage compartment.

[0021] According to some embodiments, the rib can be formed integrally with the inner surface of the door. The rib can, for example, be formed integrally with the interior panel. Alternatively, the rib can be attached to the inner surface, e.g., to the interior panel. Thus, the rib can be mounted on the inner surface of the door together with the functional unit.

[0022] According to some embodiments, it can be provided that the rib is detachably attached to the inner surface. For example, it can be provided that the rib is screwed or latched to the inner panel. For example, latching elements can be formed on the rib, which are designed for positive engagement with latching elements on the inner panel of the door. In particular, it is conceivable that latching hooks are formed on the rib, which engage in undercuts formed on the inner panel. The detachable attachment of the rib facilitates the assembly and disassembly of the rib. Furthermore, modular manufacture or production of the door can be facilitated, since different ribs can be easily attached to one and the same door.

[0023] According to some embodiments, the rib can be arranged in an end region of the door with respect to a vertical direction extending parallel to the door's rotation axis. In this way, the rib is positioned at the top or bottom edge of the door. This facilitates the illumination of the interior surface of the door and the detection of a large field of view by a sensor.

[0024] According to some embodiments, it can be provided that the body has a floor, optionally with feet projecting therefrom, and a ceiling which is arranged opposite the floor with respect to the vertical direction, wherein the rib is arranged in an end region of the door facing the ceiling.

[0025] According to some embodiments, the household appliance can have a seal protruding from the inner surface of the door, wherein the rib is arranged within a region of the inner surface delimited by the seal, in particular directly adjacent to the seal. By positioning the rib within the region delimited by the seal, a gap is formed between the rib and the seal. When the door is closed, the rib forms a partition which ensures that cold air from the storage compartment does not come into direct contact with the seal. This reduces the likelihood of condensation forming on the seal. This effect is greater the smaller the distance between the seal and the rib. The seal thus advantageously fulfils several functions.

[0026] According to some embodiments, the seal may define a substantially rectangular region of the inner surface having opposing first sides and opposing second sides, the first sides having a smaller length than the second sides, and the rib being positioned immediately adjacent to the seal on one of the first sides.

[0027] Further features of the invention emerge from the claims, the figures and the description of the figures. The features and combinations of features mentioned above in the description, as well as the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respective combination specified, but also in other combinations or on their own, without departing from the scope of the invention.

Embodiments and combinations of features are also to be regarded as disclosed that therefore do not have all the features of an originally formulated independent claim.

[0029] In the figures, the same reference symbols denote identical or functionally identical components, unless otherwise stated. DETAILED DESCRIPTION OF EMBODIMENTS

[0030] The terms “top”, “bottom”, “front”, “back”, “horizontal”, “vertical”, “depth direction”, “transverse direction”, “vertical direction” indicate the positions and orientations given when the device is used and positioned as intended.

[0031] Fig. Figure 1 shows an example of a household appliance 100 in the form of a refrigerator. However, the invention is not limited to this, but can be used generally in household appliances, in particular household refrigeration appliances.

[0032] As in Fig. 1 schematically shown, the household appliance 100 has a body 1 and a door 2.

[0033] The body 1 can have a plurality of walls 12, 13, 14, 14, 16, which together delimit a storage compartment 10 accessible through an access opening 11. For example, the body 1 can have a floor 12 and a ceiling 13 opposite the floor 12 with respect to a vertical direction V, as well as side walls 14, 15 opposite one another with respect to a transverse direction C, which extend in the vertical direction V between the floor 12 and the ceiling 13. With respect to a depth direction T, the storage compartment 10 can be delimited by a rear wall 16 of the body 10, which extends in the vertical direction V between the floor 12 and the ceiling 13 and in the transverse direction C between the side walls 14, 15. The access opening 11 is delimited by the side walls 14, 15 and by the floor 12 and the ceiling 13.

[0034] A refrigerant circuit (not shown) can be thermally coupled to the storage compartment 10 in order to extract heat from the storage compartment 10 by evaporating refrigerant and to release the heat to the environment by condensing the refrigerant.

[0035] Door 2 can, as in Fig. 1, be a substantially plate-shaped component. The door 2 is pivotally mounted on the body 1 about a rotation axis A2. As shown in Fig. As shown in Figure 1, the rotation axis A2 can extend in particular in the vertical direction V and can be arranged, for example, in the region of the side wall 14. The door 2 is mounted so as to be movable about the rotation axis A1 between a closed position and an open position. Fig. 2 shows the door 2 in the open position, in which the door 2 at least partially exposes the access opening 11. In the closed position, the door 2 at least partially covers the access opening and is positioned opposite the rear wall 16. In general, an inner surface 2i of the door 2 faces the storage compartment 10 in the closed position.

[0036] The Fig. 4 to 8 show doors 2 in a sectional view. For example, in Fig. 4, the door 2 can have an inner lining 26, an outer lining 27 and a thermal insulation layer 28 which is arranged between the inner lining 26 and the outer lining 27. The inner lining 26 can, for example, be made of a plastic or a metal material and manufactured using an injection molding or a deep-drawing process. The outer lining 27 can also be made of a plastic or a metal material. The insulation layer 28 can, for example, be formed by a foam material. In the closed position of the door 2, the inner lining 26 faces the storage compartment 10. The inner surface 2i of the door 2 is formed by an outer surface 26a of the inner lining 26.

[0037] Again with reference to Fig. 1, it can be seen that the door 2 has a rib 20 on the inner surface 2i, which extends in a direction transverse to the rotation axis A2. The rib 20 protrudes from the inner surface 2i. As shown in Fig. 1, the rib can have a longitudinal extension L20 that extends substantially over the entire width of the door inner surface 2i, e.g., over at least 75%, in particular over at least 85% of a width B2 of the door inner surface 2i in a direction perpendicular to the rotation axis A2. Alternatively, it is conceivable for the rib 20 to extend only over a range of 5% to 15% of the width B2 of the door inner surface 2i. In general, the rib 20 can extend over a range between 5% and 100% of the width B2 of the door inner surface 2i.

[0038] As in the Fig. 4 to 6, the rib 20 can be formed integrally with the inner surface 2 of the door 2. For example, the rib 20 can be formed by a molding of the inner lining 26. Alternatively, the rib 20 can also be realized as a separate component from the door 2, in particular from the inner lining 26, and can be attached to the inner surface 2i of the door 2. This is shown by way of example and purely schematically in Fig. 8, which shows a door 2 in which the rib 20 is locked to the interior panel 26 by means of locking elements 29. It would also be conceivable to screw the rib 20 to the door 2, e.g., the interior panel 26, or to removably attach the rib to the door 2 in another way.

[0039] The rib 20 protrudes from the inner surface 2i of the door 2 and defines an interior or receiving space 25. The rib 20 may, for example, have a U-shaped or substantially U-shaped cross-section, as shown in the Fig. 4 to 6 and 8 are shown as examples. However, the invention is not limited thereto; rather, a rib 20 with a trapezoidal or other cross-section may also be provided.

[0040] As in the Fig. 4 to 8, the rib 20 may have a recess 23. The recess 23 may, for example, be formed as a depression or trough in an outer surface 20a of the rib 20, as shown schematically in Fig. 6. The outer surface 20a of the rib 20 continues the inner surface 2i of the door 2 or the outer surface 26a of the inner container 26. An inner surface 20b of the rib 20, which defines the receiving space 25, is located opposite the outer surface 20a. Alternatively to a depression or trough, the recess 23 can also be designed as a through-opening extending between the outer surface 20a and the inner surface 20b of the rib 20, as shown in the Fig. 4, Fig. 5 and Fig. 8 is shown by way of example. The recess 23 can, for example, be formed in a section of the rib 20 facing away from the inner surface 2i or parallel to the inner surface 2i, as shown in Fig. 5 is shown purely by way of example. Alternatively, the recess 23 can also be formed in a section of the rib 20 extending transversely to the inner surface 2i, as shown in the Fig. 4, Fig. 6 and Fig. 8 is shown purely by way of example, in particular in a section of the rib 20 which, with respect to the vertical direction V, faces the bottom 12 of the body 1.

[0041] Again with reference to Fig. 1 shows by way of example that the rib 20 can be arranged in an end region 2B of the door 2 facing the ceiling 13 with respect to the vertical direction V. In general, the rib 20 can be arranged in an end region 2A, 2B of the door 2 with respect to the vertical direction V. As shown in the Fig. 2 and Fig. 3 purely by way of example, the rib 20 can be arranged directly adjacent to an optional seal 4 protruding from the inner surface 2i of the door 2. The seal 4 runs as a closed frame on the inner surface 2i of the door, e.g., as a substantially rectangular frame. The rib 20 is arranged within the area of ​​the inner surface 2i delimited by the seal 4, e.g., on a short side of the rectangle delimited by the seal 4, which is positioned with respect to the vertical direction V in the end area 2B of the door 2 facing the ceiling 13, as shown in the Fig. 2 and Fig. 3. The rib 20 located directly adjacent to the seal 2 forms a barrier for the cold air in the storage compartment 10 that rests against the inner surface 2i of the door 2 in the closed position, making it difficult for the cold air to reach the seal 4. This prevents condensation from forming on the seal 4.

[0042] As in the Fig. 2 and Fig. 3 purely schematically, a functional unit 3 is attached to the rib 20. The functional unit 3 can, for example, have a lighting 31 and / or a sensor arrangement 32. In the Fig. 2 and Fig. 3, the functional unit 3 is shown only as a block. This also applies to the Fig. 4, Fig. 6 and Fig. 8, which are intended to represent an example of a lighting unit 31 as a functional unit 3.

[0043] Fig. 7 shows an example of a sectional view of door 2 from Fig. 4. As in Fig. As can be seen in Figure 7, the lighting unit 31 can comprise one or more illuminating means 31A, e.g. in the form of LEDs. The illuminating means 31A can be aligned substantially parallel to the inner surface 2i of the door 2 in order to emit light across the inner surface 2 and to illuminate it. Fig. 1, the inner surface 2i can thus be illuminated from the upper end area 2B. In the case of the doors 2 shown in the Fig. 2 and Fig. 3, the optional shelves or shelf elements 7 attached to the inner surface 2i of the door 2 can be illuminated.

[0044] Fig. Figure 5 shows an example of a functional unit 3, which comprises a sensor arrangement 32 with an optical sensor. For example, the sensor arrangement 32 can be a camera with an imaging sensor, e.g., a CMOS sensor or an infrared sensor. If the sensor, as in Fig. 5, oriented away from the inner surface 2i, the storage compartment 10 lies within the field of view of the sensor when the door 2 is in the closed position. Thus, the contents of the storage compartment 10 can be reliably detected by the sensor.

[0045] As in the Fig. 4 to 6 and 8, the functional unit 3 can be at least partially accommodated in the recess 23. If the recess 23 is as shown in the Fig. 4, Fig. 5 and Fig. 8 is designed as a through-opening, the functional unit 3 can be at least partially accommodated in the receiving space 25. In general, the functional unit 3 can be designed as an elongated unit, in the case of a lighting 31, for example, as a light bar, as shown in Fig. 7 is shown schematically. In general, the functional unit 3 can extend at least partially along the longitudinal extent L20 of the rib 20.

[0046] The functional unit 3 is attached to the rib 20. In particular, the functional unit 3 can be detachably connected to the rib 20. In the Fig. 4 and Fig. Figure 5 schematically shows a locking of the functional unit 3 to the rib 20 via locking elements 33. Of course, other detachable fixations, such as a screw connection, are also conceivable.

[0047] By integrating a functional unit 3 into the rib 20, the functional integration in the door 2 is increased in a space-saving manner, since the rib 20, in addition to its function as a barrier for cold air, also serves as a support structure for a lighting unit 31 and / or a sensor arrangement 32. In the case of a lighting unit 31, the inner surface 2i of the door 2 can be easily illuminated. In the case of a sensor arrangement 32, the sensory monitoring of the storage compartment 10 is facilitated.

[0048] Although the present invention has been explained above using exemplary embodiments, it is not limited thereto but can be modified in a variety of ways. In particular, combinations of the above embodiments are also conceivable.
