Definitions
- the invention relates to a household refrigerator or freezer with a heat-insulated housing enclosing a cold room, that can be closed by a door on its open front and with one between the rear wall of the refrigerator compartment and one air duct formed in front of this arranged intermediate wall, in an air flow from a fan for circulating the cooling air is blown in, the airflow with one Flows through plate-shaped evaporator.
- a cabinet is e.g. known from GB-A-1 457 871.
- a major disadvantage of this Known cooling device is that not only a plate-shaped Evaporator, but also an intermediate wall distributing the cooling air must become.
- Evaporator and partition wall fulfill two completely separate functions: during the plate-shaped evaporator the through cools the air drawn in by the fan, the intermediate wall forms a cooling air duct and at the same time prevents a fluidic short circuit, the without the partition would be created by the fan continued air is sucked in immediately.
- the flat evaporator behind which the back wall foaming plastic plate foamed into the rear wall of the refrigerator, and an intermediate wall is arranged in front of the rear wall, the one on the back with a fan-like structure formed by bridges Arranged air duct is provided in different Exit high altitudes and by redirection or changes a different heat exchange in their cross-section of the air flow in the ducts on the through the rear wall allow formed cooling surface of the evaporator.
- the distance between the intermediate wall and the rear wall corresponds to in about the width of the webs delimiting the air duct.
- the known refrigerator is relatively expensive because not only a foamed, flat evaporator is provided must be, the effectiveness of which is also through the insulating, concealed arrangement is reduced, but in addition yet another cooling air ducts which distribute the cooling air Intermediate plate must be provided.
- the object of the invention is therefore a refrigerator of the beginning to create specified type, which at an improved Efficiency has a simpler construction.
- this object is achieved in that the partition is formed by the plate-shaped evaporator.
- the refrigerator according to the invention is characterized by a simplified one Build out because once on the partition has been waived and on the other hand through the intermediate plate distributing the cooling air the evaporator itself is formed.
- the evaporator itself also makes a good one Efficiency achieved because the cooling air swept on all sides Evaporator its refrigerating capacity directly to the cold room emits cooling cooling air.
- the shape, size and distribution the passage column can be chosen so that accordingly optimal distribution and circulation the cooling air is reached in the cold room.
- the plate evaporator is expediently provided with horizontal ones Provide passage slots. Of course you can these through slots may also be interrupted if this due to the routing of the coolant channels in the evaporator plate is required.
- the shelves, shelves and / or drawers are expediently on the side walls of the refrigerator compartment, each shelf or the like. At least one passage slot is assigned.
- the passage slots can also protrude into the cooling air duct Air guiding surfaces should be provided, the length, shape and inclination of which Desired cooling air distribution in the cold room can be adjusted.
- the housing of the refrigerator consists of a not shown outer wall and a trough-shaped inner wall 1, the space between the walls with an insulating Plastic foam 2 is foamed.
- the cooling room 3 is limited by conventional air guiding surfaces a blower 4 which can be driven by an electric motor is arranged, which draws 3 cooling air in the direction of arrow A from the cooling space and blows in the direction of arrows B into a cooling air duct 5, the between the rear wall 6 of the refrigerator 3 and the plate-shaped Evaporator 7 is formed, which is at a distance from the rear wall 6 is held approximately parallel to this in the cold room 3.
- the plate-shaped evaporator 7 is at a distance from the rear wall 6 arranged that on the one hand a sufficiently wide, the Cooling air distributing and circulating channel formed and on the other hand the usable space of the refrigerator is not disadvantageously reduced is.
- the plate-shaped evaporator 7 is horizontal Provided passage gaps 8 through which the cooling air in the direction the arrows drawn from the cooling air duct 5 in the Cold room 3 enters.
- the passage gaps are in the cooling air duct 5 protruding cooling air guiding surfaces formed by angled sheets provided, their shape, size and angle of inclination selected according to the desired cooling air distribution can. Laterally, the plate-shaped evaporator can directly or forming gaps on the side walls of the cold room connect.
- the gaps 8 delimited by the guide surfaces 9 expediently open between the individual shelves 10 in the refrigerator, the held in the usual way on the side walls of the refrigerator are.
