Description

The present invention relates to a cooler device, preferably freezer device or chiller device, comprising a cabinet, at least one door, at least one display and at least one product storing region being located inside the cabinet.
Further, the present invention relates to a door for use with a cooler device.
Cooler devices are used for example in supermarkets and convenience stores for presenting cooled or frozen goods. Traditional devices have large header structures above the doors for mounting a display. These displays are used for promoting specific products or actions at the point of sale. Further, displays help to support the consumer with regard to the in-shop orientation and navigation and to provide product information at the point of sale. Furthermore, these displays enable the merchant to inspire the consumer and to trigger purchasing decisions.
Existing solutions which address the topic of promotion are often based on screens which are integrated into the transparent area of the door. Such screens are opaque, transparent or translucent. A corresponding cooler device is shown in the US patent application US 2013/0063326 A1 .
These cooler devices have the disadvantages that they are expensive and require high initial investments due to the use of expensive screens and the complicated production process. Due to the integration of a screen into the door body such solutions are not flexible and can e.g. not be exchanged to use later technical solutions. Even if they are semi-transparent the screens according to the state of the art block at least partly the view of the customer to the presented goods inside the cooler device. Another problem is that to achieve the contrast which is necessary the light level in such arrangements has to be increased which is increasing the energy consumption significantly. The waste heat which is generated by such additional light sources is at least partly generated in the cooled area. In case digital displays are used the necessary electronic components are at least partly exposed to low temperatures and temperature changes which increase the risk of condensation and humidity on the components and therefore potentially decrease the lifetime of the device. In case the merchant would like to change positions the effort for changing displays is very high because complete doors have to be changed.
Alternatively - especially for the purpose of navigation and orientation support - stickers are placed on the doors or billboards are placed on top of the doors in the cabinet header. Due to aesthetical reasons, this approach is not preferred by retailers anymore.
Embodiments of the present invention therefore address the problem of improving and further developing a cooler device and a door for a cooler device such that a display can be provided without reducing the product visibility.
In an embodiment the present invention provides a cooler device, preferably freezer device or chiller device, comprising a cabinet, at least one door, at least one display and at least one product storing region being located inside the cabinet, wherein said door comprises a transparent product presentation area and a display area, wherein under an frontal view said product storing region is viewable through said transparent product presentation area, wherein said transparent product presentation area and said display area do not overlap with each other, such that under an frontal view the product storing region is unobstructed by the display area, and wherein said display area is at least partly transparent, such that said display is viewable through said display area or wherein said door comprises said display, such that said display defines said display area.
In a further embodiment, the present invention provides a door for use with a cooler device according to any one of the claims 1 to 13, comprising a transparent product presentation area and a display area, wherein under an frontal view a product storing region is viewable through said transparent product presentation area, wherein said transparent product presentation area and said display area do not overlap with each other, such that under an frontal view the product storing region is unobstructed by the display area, and wherein said display area is at least partly transparent, such that a display is viewable through said transparent display area or wherein said door comprises said display, such that said display defines said display area.
The term "display" refers in particular in the claims, preferably in the description to a device for displaying information. The information can be indicia, such as number or letter, a color or the material of the display itself for the use of promotion, trigger purchasing decision, support the consumer with regard to in-shop orientation etc. The term "freezer device" refers in particular in the claims, preferably in the description to a device in which the temperature of the foodstuffs is typically kept between -12°C and -30 °C on normal conditions of use. Normal conditions are defined as operating conditions, which exist when the cabinet, including all permanently located accessories, has been set up and situated in accordance with the recommendations of the manufacturer and is in service. Typical examples for such foodstuffs are the products which are stored according to EN23953, part 2 (September 2012) in the temperature classes L1, L2 and L3.
The term "chiller device" refers in particular in the claims, preferably in the description to a device in which the temperature of the foodstuffs is typically kept between -5°C and +10°C on normal conditions of use, preferably between 0°C and +7°C. Typical examples for such foodstuffs are the products which are stored according to EN23953, part 2 (September 2012) in the temperature classes M1 and M2.
The term "transparent" refers in particular in the claims, preferably in the description to a region, area or the like which is optically provided such that the view on the goods, products or the like inside the freezer or chiller device is not obstructed or blocked.
The term "frontal view" refers in particular in the claims, preferably in the description to a person view when a person is standing in front of the closed door and looking into the device under approximately 90° with respect to the surface of the closed door.
One of the advantages is that the view onto the product presentation area is not blocked since the transparent product presentation area and the display area do not overlap with each other. Hence, a display for promotion, in-shop orientation etc. can be realized in the display area without disturbing a consumer's view on the products stored in the device. A further advantage is that an appealing look of the device is created since the display area is a part of the door.
In a preferred embodiment, the display area is arranged above the product presentation area. Hence, the information is viewable even from long distances. According to a further embodiment said door extends essentially to a top edge and/or to a lower edge of said cabinet. Preferably the door is 10 cm higher or lower than the top edge and/or the lower edge of said cabinet. More preferably the door is 5 cm higher or lower than the top edge and/or the lower edge of said cabinet. It is noted that the term "essentially" refers to a construction according to which the door is designed with respect to the cabinet in such a way that for an average sized customer it appears as if the door is flush with the top edge of the cabinet. This has the advantage that an appealing design of the device is achieved.
In a preferred embodiment, a front of said product presentation area and a front of said display area are defined by a single glass sheet. Providing a single glass sheet has the advantage that the surface of the door can be cleaned easily. A further advantage is the appealing design of such a surface.
According to a further embodiment, said product presentation area and/or said display area is/are defined by a gas-filled insulating glass unit or by a vacuum insulated glass unit. This provides the advantage that the inside of the device is insulated against the warm ambient air. Typically, the gas filled insulating glass unit and/or the vacuum insulated glass unit comprise at least two glass panes, often three glass panes, being spaced apart from each other by one or more spacers. The glass panes may comprise a thickness of 3 mm to 5 mm, often 4 mm and/or may comprise an antifog-coating or an antifog foil and/or a heatable coating and/or a low-emissivity coating and/or an anti-reflective coating. In vacuum insulation glass units (VIG) the spacer elements may have a depth of 0.5 mm to 1.5 mm, preferably of below 1 mm. These spacer elements of the VIG are used in combination with a circumferential edge sealing. In gas filled insulation glass units (IG) the circumferential spacer may have a depth of 4 to 20 mm. The space between the glass panes can be filled with a gas in case of an insulating glass unit (IG) or may be evacuated in case of a vacuum insulated glass unit (VIG). For not obstructing the view through the glass units the spacers can be made of a transparent material.
According to another embodiment, the display area is defined by an extended front glass of said gas-filled insulating glass unit or by an extended front glass of said vacuum insulated glass unit. This has the advantage that a transparent display area can be achieved easily. Furthermore, a single glass sheet defines the surface of the transparent product presentation area and the display area, which makes this surface easy to clean.
In another embodiment, said presentation area and said display area are defined by separate glass sheets. Hence, the product presentation area and the display area are optically distinct from each other such that a customer can easily distinguish these two areas. According to a further embodiment, at least one connection element can be provided between said separate glass sheet. The connection element can have at least essentially a T-shaped or a U-shaped or an H-shaped or a Z-shaped cross section. Furthermore, the connection element can be made of a soft material to avoid damages due to direct glass-to-glass contact. Moreover, the connection element can be translucent, transparent or colored. The term "essentially" with regard to the term relating to a shape, form or the like of an element refers not only to the strict form, shape or the like but also to a shape, form or the like which deviates from the strict form, for instance by rounded corners, different formed connections between corners or the like.
In another embodiment, said display is mounted to said door. According to this embodiment, the display moves together with the door when the door is closed or opened. Therefore, the display will always be connected to said door which allows the customer to have the information provided by said display even though the door is in its open position. In a preferred embodiment, the display area is transparent, for example defined by a glass sheet, and the display is mounted to the door, behind das transparent display area. Thereby, a full glass door can be realized which has an appealing design and is easy to clean.
According to a further embodiment, said display is mounted to said cabinet. Hence, the information of the display will always be close by the products being stored in the device, regardless of whether the door is in the closed position or in the opened position. Furthermore, the wiring of the display is easy to establish when the display is mounted to the cabinet.
According to a further embodiment, said display is detachable mounted to said door and/or to said cabinet. Thereby the display itself can be replaced such that the information being presented to the customer can be changed easily. The display can be mounted to the door and/or to the cabinet with a form-fit and/or a force-fit connection. For example, the display can be mounted to the door and/or the cabinet with mounting means such as a clip.
In a preferred embodiment, said display is defined by a screen, preferably an LED-Screen or an LCD-Screen or an OLED-Screen. This has the advantage that the information shown on the screen, i.e. on the display, can be changed easily. According to a further embodiment, said display is defined by a projection surface.
According to another embodiment, said display is defined by a panel, preferably a printed cardboard panel or a printed glass panel or a printed metal panel. The panel can be made of any suitable material. This is a very easy and cheap solution for realizing a display. Furthermore, the panel could be detachable mounted to the door or to the cabinet with a form-fit and/or a force-fit connection. For example the panel could be slided behind the transparent display area or could be mounted to the door or cabinet with a clip.
In a further embodiment, said door is a sliding door or a swing door. Providing a sliding door is advantageous because only a minimum of space in front of the device is needed. A swing door has the advantage that the door does not block further areas of the device when it is in its open position.
According to another embodiment, said display is inclined towards the plane in which the display area is arranged, when the door is in its closed position. Inclining the display makes it for a customer easier to view the display, especially when the display area is arranged above the product presentation area.
