- U.S. Pat. No. 7,856,845 discloses a refrigerating device having a cooling compartment that can be closed by a door. The door has a heat insulated inner lining and a cooling air duct. The cooling air duct in the door conducts air cooled by an evaporator to the cooling compartment and the cooling air duct is recessed in the heat insulation of the door and is not covered by the heat insulation on the side facing the inner lining of the door.

In particular, the home appliance device comprises, in at least one operating state, the home appliance door. The appliance body and the home appliance in particular define the storage space in at least one operating state at least substantially and preferably by considering tolerances completely. The appliance body in particular contains at least two, in particular at least four and preferably at least five walls. The walls in particular delimit the storage space. The walls may in particular be embodied as a lateral wall and/or as a rear wall and/or as a bottom wall and/or as a top wall.

- In a possible embodiment of the invention, air-guiding channel comprises completely undulated base wall.
- In a possible embodiment of the invention, the air-guiding channel contains at least one ridge. In a possible embodiment of the invention, the ridge is formed on the base wall of the air-guiding channel. The ridge extends along the air channel almost entirely in a longitudinal manner. Thus, the air-guiding channel is strengthened for foaming process.
- In a possible embodiment of the invention, the ridge contains at least one gap for distributing air along the air channel in a balanced manner. Thus, the air can flow through the gap so as to expand to entire surface of the air-guiding channel. Using of entire surface of air guiding channel provides better air circulation and better heat transfer for cooling storage chamber in a shorter period. In a possible embodiment of the invention, the ridge contains a plurality of gaps.
- In a possible embodiment of the invention, the air-guiding channel contains a plurality of ridges separated by gaps. Thus, instead of forming a single ridge extending along the air channel in a longitudinal manner, a plurality of ridges can be formed intermittently. The ridges can be aligned in a longitudinal manner.
- In a possible embodiment of the invention, the air-guiding channel has an end portion inclined laterally towards the longitudinal center of the inner wall. In a possible embodiment of the invention, the ridge has an end portion inclined laterally towards the longitudinal center of the inner wall. Thus, air can be guided into the air-guiding channel efficiently and possible condensation problem can be prevented.
- In a possible embodiment of the invention, air-guiding channel has an end portion inclined towards the cover element. Thus, the possible condensation problem can be prevented by obtaining substantially rounded air line between the cover and inner wall. In a possible embodiment of the invention, height of the ridge at the region of the end portion can be decreased towards the end of the channel.
- In a possible embodiment of the invention, the air-guiding channel is formed on the inner side of the inner wall. Thus, air-guiding duct placed between the inner wall and the outer wall can be eliminated and so the remaining volume between the inner wall and outer wall is filled with foam. Thicker foam layer provides better insulation and efficient cooling performance. Inner side of the inner wall is the side facing towards the cover wall.
- In a possible embodiment of the invention, the inner wall contains at least two air-guiding channels. In a possible embodiment of the invention, the inner wall contains three air guiding channel. In a possible embodiment of the invention, the inner wall contains a barrier between air guiding channels for separating the air channels. The barrier is formed integrally on the inner wall. The barrier is a separating wall extending longitudinally. Length of the barrier is substantially equal to the length of the air channel. In a possible embodiment of the invention, the inner wall comprises two barriers between air guiding channels for separating the air channels
- In addition, the invention is a home appliance, in particular a cooling device, containing at least one home appliance door.
- In a possible embodiment of the invention, the inner wall and air-guiding channel are manufactured in one piece. In a possible embodiment of the invention, the ridge and the inner wall are manufactured in one piece.
- In this context, with the indications “top”, “bottom”, “front”, “rear”, “horizontal”, “vertical”, “upward”, “downward”, “inner”, “outer”, “inward”, “outward” etc. the positions and orientations given for intended use and intended arrangement of the cooling device and for a user then standing in front of the cooling device in a closed position and viewing in the direction of the device are indicated.
- Each possible embodiment disclosed in this text can be combined with the other possible embodiments disclosed in this text if there is no any technical constraint.
- The figures, whose brief explanations are herewith provided, are solely intended for providing a better understanding of the present invention and are as such not intended to define the scope of protection or the context in which said scope is to be interpreted in the absence of the description.
- Other features which are considered as characteristic for the invention are set forth in the appended claims.
- Although the invention is illustrated and described herein as embodied in a home appliance door having an air-guiding channel, it is nevertheless not intended to be limited to the details shown, since various modifications and structural changes may be made therein without departing from the spirit of the invention and within the scope and range of equivalents of the claims.
- The construction and method of operation of the invention, however, together with additional objects and advantages thereof will be best understood from the following description of specific embodiments when read in connection with the accompanying drawings.
-
FIG. 1 is a diagrammatic, perspective view of a home appliance according to the invention; -
FIG. 2 is an exploded, perspective view of a home appliance door; -
FIG. 3 is a perspective view of an inner wall; -
FIG. 4 is a front view of the inner wall; -
FIG. 5 is a cross-sectional view of an air-guiding channel; -
