Description

A COOLING DEVICE

The present invention relates to a cooling device comprising a visual detection means.

In cooling devices, visual detection means that are arranged on the door, the body or on the shelves on the door and that enable the visual data of the interior of the cooling device to be transmitted to the users are used. In such cooling devices, the obtained visual data can be transmitted to an image display device arranged on the cooling device body by means of the cable or wireless network connection feature of the cooling device. Similarly, said visual data can be transmitted to external and portable image display devices owned by the user with wireless network connection feature. Said visual data provides the user with the information about the interior of the cooling device but due to the positioning of the visual detection means, the latter also invades the privacy of the user by obtaining the visual data related to the user and the user's living environment. Considering the weak security measures of the wireless network connections, this situation may pose a threat to the privacy of the user.

Another problem in the cooling devices comprising a visual detection means is encountered when the related image is tagged by the user after the obtained visual data is transferred to the image display device. The user can create tags by entering information such as the expiry date, package opening date etc. of the items and place the same on the images of the items displayed on the image display device. However, when the user takes the item out of the cooling device and places the same at another location after use, the user has to move the tags to the new position of the foodstuff, delete the tag and create new one or place the foodstuff to its previous position since said tags remain in the first position determined by the user on the image display device.

In the state of the art Patent Document No. EP2843337, a cooling device is disclosed, wherein a visual detection means is used.

The aim of the present invention is to assign to the new position of the foodstuff without the need for user intervention the tag previously created on the image display device by the user including information such as the expiry date, the package opening date etc. of the foodstuff when the positions of the foodstuffs to be cooled in the cooling device are changed.

In the cooling device realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, the foodstuffs placed in the cooling device to be cooled are isolated from the outer environment by means of a body with insulation properties. The door mounted to the front side of the body enables the user to access to the interior of the body in the open position and thermally insulates the interior of the body from the outer environment in the closed position. In the body, body shelves placed between the two opposite lateral walls of the body and whereon the foodstuffs to be cooled are placed are provided. Door shelves are arranged on the surface of the door facing the inner surface of the body. Said door shelves comprise a base and two side walls that extend perpendicularly to the base from the opposite edges of the base. The first side wall is positioned on the side of the door that moves relative to the body and the second side wall is positioned on the side that faces the user in the open position of the door. A visual detection means is arranged on the side of the first side wall where the door is hinged to the body. As the door moves from the open position to the closed position and from the closed position to the open position, the visual detection means obtains the visual data of the interior of the body and transmits the same to the control unit positioned in the cooling device. By arranging the visual detection means on the first side wall, in cases when the door is opened with a wide angle, the field of view of the visual detection means is limited to the interior of the body, the body shelves and the foodstuffs placed on the body shelves, and thus, the privacy of the user is provided by preventing the visual detection means from recording visual data related to the user. Thus, the product perception is improved.

In an embodiment of the present invention, the cooling device comprises doors that extend along the body, that are positioned parallel to each other and that can be opened and closed independently. By means of a plurality of doors and the visual detection means arranged on the first walls of the door shelves on said doors, the visual data of the interior of the body, the body shelves and the foodstuffs placed on the body shelves is collected from more than one angle. Thus, the visual defects that may occur as a result of the rotation movement during the opening-closing of the door are prevented and the product perception is improved.

In an embodiment of the present invention, the field of view of the visual detection means positioned on the first wall is limited by the body shelf edge of the body shelf which is at the same vertical position as the said visual detection means and that is positioned on the body inner wall which is the farthest from the visual detection means. Thus, the user is prevented from entering the field of view of the visual detection means regardless of the opening angle of the door, and the user privacy is ensured.

In an embodiment of the present invention, the visual data obtained by means of the visual detection means is processed by means of the control unit and transferred to the image display device. The connection between the control unit and the image display device can be provided with a cable system arranged in the cooling device or the data can be transferred to an external image display device owned by the user via the wireless network connection feature of the control unit. Thus, the user can access the latest visual data related to the interior of the cooling device and the ease of use is provided while the product perception on the user is improved.

In an embodiment of the present invention, the user can create tags on the image display device displaying the image of the foodstuffs that is obtained by the visual detection means such that the tags correspond to the positions of the foodstuffs. The content of said tags can be provided as templates that are prepared in advance according to user needs, and the user is enabled to enter customized data independently of the templates. Said data may include the information regarding the expiry dates of the items, the package opening date of the foodstuffs and tags that indicate ownership in cases when the cooling device is used by a plurality of users. By means of tagging, the expiry dates of the foodstuffs in the cooling device can be monitored.

In an embodiment of the present invention, when the door is in the open position, by means of the visual detection means, the control unit can track the movements of the hands of the user in the cooling device and the foodstuffs that are relocated. When the user tags the foodstuff, a new tag is created on the image display device. In cases when the user takes the foodstuff out of the cooling device for use and places the same back or relocates the foodstuff in the body, tags that are idle and that do not correspond to the position of the foodstuff remain on the image display device. By means of the item recognition feature, the control unit matches the tag that is available on the image display device and that corresponds to the foodstuff with the new position of the foodstuff and automatically moves said tag onto the said foodstuff on the image display device without the need for user intervention. Thus, the quality perception of the user related to the product is improved. The present invention is also advantageous in that the user saves time as it is not necessary to move the tags to the new positions of the foodstuffs.

In an embodiment of the present invention, the visual detection device comprises a wide-angle lens. The wide-angle lens scans a wide angle in the body during the opening and closing of the door and thus, obtains the visual data of a larger volume. Consequently, the need for a second visual detection means is eliminated and the costs are reduced.

In an embodiment of the present invention, the image display device is arranged on the door of the cooling device. Thus, the need for the user to procure an external image display device is eliminated, and the usage costs are improved by preventing the user from covering additional costs for using the cooling device.

By means of the present invention, the user is enabled to tag the foodstuffs placed into the cooling device to be cooled on the image display device, and when the positions of said foodstuffs are changed, the related tags are automatically matched with the new positions of the foodstuffs and the corresponding change on the image display device is performed automatically by means of the control unit.
