Description

Refrigerating appliance with several storage compartments

The invention relates to a refrigeration device, in particular a household refrigerator, with several storage compartments. The display of the operating status of conventional refrigerators with several

Storage compartments are usually limited to a central small display, usually displaying various temperature values and status displays. A direct visual assignment to the individual storage and cooling compartments does not exist, or only indirectly through pictograms in the central display.

EP 1 814 003 A1 discloses a refrigerator with a door having a projector for projecting device information or a device operating parameter onto the projector

Outside of the door has. The projector can also be arranged inside the device and project its information onto a device inside.

EP 1 489 364 A1 discloses a cooking, refrigerating or washing appliance with at least one projection device for projecting representable information about the function of the appliance onto a projection surface. DE 20 2007 008 843 U1 discloses a refrigerator or freezer with a door to

Closing the device interior. On the door projection means are arranged, which project information onto a projection surface arranged on the inner container.

The object of the invention is to provide an improved refrigeration device with several storage compartments.

Under a refrigeration device is in particular a household refrigeration appliance understood, ie a refrigeration appliance for household management in households or possibly in the

Catering area is used, and in particular serves to store food and / or drinks in household quantities at certain temperatures, such as a refrigerator, a freezer, a fridge freezer, a freezer or a wine fridge. The object of the invention is achieved by a refrigeration device, comprising a body with a coolable interior, one for opening and closing the interior

provided, hinged to the body door leaf, a plurality, in particular separated by shelves and disposed within the refrigerator storage compartments and a projection device for projecting an image on a projection surface. The projection device is set up to project one image onto projection surfaces of the individual storage compartments, wherein the respective images have information about the respective storage compartment and / or information about refrigerated goods to be stored and / or stored in the respective storage compartment. The refrigerator according to the invention therefore comprises the coolable interior, which in turn is divided into several storage compartments. The storage compartments can preferably be separated from each other by shelves. The refrigerator also has the

Projection device on. This is according to the invention set up such that for each storage compartment a picture on a corresponding projection surface of the question

Storage compartment projected. The respective images in turn include an indication of the respective storage compartment, e.g. the temperature of the same, and / or an indication of refrigerated goods to be stored and / or stored in the respective storage compartment. This results in a relatively comfortable storage management system for a refrigeration appliance or a projection of warehouse management information in cooling or refrigeration appliances, since a user of the

Refrigeration device in a relatively simple manner can read information about the storage compartments and / or stored refrigerated goods and / or stored refrigerated goods.

The projection device of the refrigerator according to the invention is designed according to a preferred embodiment such that it has a plurality of projectors, which are assigned to the respective storage compartments and according to the

Storage compartments project their image onto the corresponding projection screen. The individual projectors can be aligned in a relatively simple manner so that they can project their images onto the desired projection surfaces. The projection surfaces can be, for example, at least partial surfaces of an inner wall of an inner container delimiting the inner space. This inner wall is preferably a side wall. Then it is possible that the desired information is projected on a side surface of the storage compartment in question in order to read it. If the storage compartments are limited by shelves, then it is also possible that the projection surfaces represent at least partial surfaces of the shelves delimiting the storage compartments. The projection surfaces are then preferably in the front area of the shelves, whereby the content in question of the projected images are relatively well visible.

The projection device can preferably be arranged on the body and / or in the cold room. This allows the projection device to be relatively well aligned to project its images onto the desired projection surfaces. According to a preferred variant of the refrigerator according to the invention is the

Projection device arranged in a bar. This can be done in a relatively simple manner e.g. be attached to the inner container or on the body.

The bar may in particular be vertically aligned. This is advantageous if the storage compartments are arranged one above the other. The strip may preferably be arranged in a front region of the cold room, in particular on the body.

According to one embodiment of the refrigerator according to the invention, the strip is arranged in the region of a further inner wall of the inner container, which lies opposite the inner wall, which in particular comprises the projection surfaces. Then there are favorable conditions for an undisturbed projection of the images on the desired projection surfaces even with a refrigerator loaded with refrigerated refrigeration device according to the invention.

The strip can also run in the range of door hinges, by means of which the door leaf is hinged to the body.

The information of the projected images can be written, for example, in a country-specific plain text, in particular with a font size between 20 and 25 mm, an indication of the type of food, the temperature of the respective storage compartment, a

Storage date and / or expiry date of a particular item to be cooled, or one

Note on an at least suitable storage compartment of a particular refrigerated goods. According to one embodiment of the refrigeration device according to the invention this has an input device which is connected to a control device of the refrigeration device and is set up that with her a Kühlgutart can be entered. The

Control device can then be configured to control the projection device such that the storage compartment is displayed by means of the projected images, which represents at least a good storage location for the entered Kühlgutart.

The invention optionally provides a numerical / character projection display which is optionally mounted in a vertical bar in the region of the hinges and in particular for the projection of warehouse management information on the side wall or shelves in the interior of refrigerators, preferably provided by refrigerators.

The stock management information displays can be:

- food type,

- storage date,

- expiration date,

- warnings when expiry date is reached,

- temperature in the individual refrigerators and storage compartments,

- search function according to the criteria: food type, date,

- Status of individual coolers and storage compartments, such as Setpoint and actual temperature,

- User guidance in country-specific plain text.

Operating element, such as. B. sensor keys or rotary selector for setting the

Warehouse management Information can be stored outside the interior of the refrigerator. An operation is possibly possible both with decided as well as opened door.

Due to the refrigeration device according to the invention, a relatively large, easy-to-read projection display can be provided in particular in country-specific plain text with eg a font height of 20 ... 25mm. It can be a unique assignment of stock management information, such as

Food grade, temperature, storage date, expiration date, to the appropriate and optimal storage compartment and cooling zones can be achieved.

The optimal cooling temperature for the item to be chilled may increase the shelf life of the food.

User guidance can be achieved by using a Charcter projection display with country-specific plain text. The presentation of the warehouse management information is close to the location, possibly program-specific and relatively legible. It is possible to represent this safe for the user.

If necessary, there is a clear individual visual warning when a food ingredient expiry date has been reached or even exceeded.

If the food type is entered, a good, if not ideal, storage location can be displayed. When using the vertical bar with projection display, this can be mounted left or right. As a result, an exchange stop of the door leaf is possible.

An indication of the exact cooling temperature per storage compartment and cooling zone can be made possible.

It is possible to configure the storage compartments individually (temperature zones), e.g. for the preferred food type.
