Abstract
A chilled goods support for a cooling device comprising a liquid crystal temperature display unit. A supporting element of said chilled goods support is used as a thermal buffer to which the liquid crystal temperature display unit is fixed in a planar manner.
Description
- The present invention relates to a cooling device, especially a chilled goods support for such a cooling device.
- The temperature distribution in the interior of a cooling device is not homogeneous, which especially in cooling devices with an internal temperature above the freezing point, allows differently temperature-controlled areas of the interior to be used for different types of chilled goods which make different demands on the storage temperature. However, a specific usage of the temperature differences in the interior for this purpose assumes that the user knows, at least qualitatively, the temperatures prevailing in the different compartments of the interior. For this purpose, an interior configuration for a cooling device has been proposed in DE 102 05 589 A1 wherein a plurality of liquid crystal temperature displays are distributed on the different compartments of the interior of a cooling device to allow the user to optimally utilise the suitability of each individual compartment for storing different groups of chilled goods.
- These temperature displays can be placed in a compartment at different locations, it being dependent on a favourable choice of location whether the temperature detected by the display is representative for the compartment of the interior where it is attached. From the point of view of a representative temperature recording, it would be desirable per se to attach a temperature display in a compartment centrally between the heat sink, usually the rear wall of the interior chamber bearing the evaporator, and the main heat source, i.e. the door seal. For this purpose however, the temperature display would need to be attached to a side wall of the inner container and such a display would be difficult for a user to read. From the point of view of readability, attachment to the front edge of a chilled goods support, facing the door of the cooling device, is to be preferred: However, such a display is subjected to strong disturbing influences from warm air which penetrates into the interior when a user opens the door so that the temperature recorded and indicated by such a display is possibly no longer representative of the stationary state of the cooling device even after opening the door for a short time.
- In order to obviate this problem, it is proposed in DE 102 05 589 A1 that the heat-sensitive liquid crystals of such a liquid crystal temperature display should be held in contact with a thermal buffer accommodated in a housing of the display in order to thus impart a desired inertia to the display.
- It is the object of the present invention to provide a chilled goods support or a cooling device with such a chilled goods support which can achieve the advantages of the known interior configuration described above by simpler and more cost-effective means.
- The object is achieved by a chilled goods support having the features of
claim 1 or a cooling device having the features ofclaim 9. - Since, according to the invention, a supporting element of the chilled goods support is used as a thermal buffer for the liquid crystal temperature display, which supporting element generally has a not insignificant mass and therefore thermal capacity as a result of its function, it is superfluous for the temperature display to have its own thermal buffer so that space and costs can be saved.
- The thermal buffer is preferably formed by a frame moulded on a plate of the chilled goods support. The temperature display unit can be located directly on this frame on a side facing the door of the cooling device in the mounted state of the chilled goods support so this can be conveniently read by a user who has opened the door.
- In the interests of good readability, it is also preferable if the liquid crystal temperature display unit is attached to an outer side of the frame oriented obliquely to the plate, which points obliquely upwards in the mounted state.
- As a consequence of a first embodiment, a portion of the frame which supports the liquid crystal temperature display unit is an extruded profile which can be formed of plastic or metal.
- The liquid crystal temperature display unit can also be arranged on a frame which is moulded in one piece around the plate of the chilled goods support.
- In order to facilitate readability, the liquid crystal temperature display unit is divided into a plurality of discrete elements each having different colour change temperatures. Alternatively, a display zone of the liquid crystal temperature display unit can be provided wherein a transition zone is continuously movable between a low-temperature colour and a high-temperature colour depending on temperature so that a user can estimate the temperature from the location of the transition zone. In order to quantify the estimate, a scale can be constructed on the supporting element adjacent to the display zone.
- Further features and advantages of the present invention are obtained from the following description of the exemplary embodiments with reference to the appended figures. In the figures:
-
FIG. 1 is perspective view of a cooling device according to the invention with the door open; -
FIG. 2 is a plan view of a first embodiment of a chilled goods support according to the invention; -
FIG. 3 is a partial plan view of a second embodiment of a chilled goods support; -
FIG. 4 is a partial plan view of a third embodiment of a chilled goods support; -
FIG. 5 is a section along the line V-V fromFIG. 4 ; -
FIG. 6 is a partial plan view of a fourth embodiment of a chilled goods support; and -
FIG. 7 is a section through the chilled goods support fromFIG. 6 along the line VII-VII. -
FIG. 1 is a perspective view of a cooling device according to the invention with thedoor 7 open. The cooling device shown comprises a refrigerator-freezer combination with a chilledcompartment 1 at the top and afreezing compartment 2 at the bottom. Although it can fundamentally also be applied to thefreezing compartment 2, the invention is described hereinafter only with reference to the chilledcompartment 1. - The chilled
compartment 1 is divided into a plurality of part compartments ofregions side walls 3 of the housing. The twolowest regions 5′ are each defined by a pull-outbox 18, theregions 5 located thereabove are open towards thedoor 7. They are cooled by an evaporator located behind therear wall 6 of thechilled compartment 1 at the height ofregion 5 which is not visible in the figure. In each of theseregions 5 there exists a non-vanishing temperature gradient from a coldest point on therear wall 6 to a warmest point near thedoor 7. Since the cold air in thechilled compartment 1 tends to sink, the lower-lyingregions 5 are generally colder than the higher ones, i.e. the global temperature difference between the warmest and the coldest point of the entirechilled compartment 1 is greater than the temperature differences existing in theindividual regions 5. - A group of comparatively
warm regions 5″ is formed by box-shaped door compartments 8 mounted on the inside of thedoor 7 as chilled goods supports. - Each
region 5 is allocated respectively one liquid crystaltemperature display unit 9 which is arranged at the front edge of a frame of thatcompartment base 4 which terminates therelevant region 5 at the bottom. Thetemperature display 9 is therefore closely adjacent to the region located thereunder but the temperature to which it is exposed is representative of the region located above thecompartment base 4 since when the door is closed, cold air from the relevant region flows downwards over the front edge of the compartment base. -
FIG. 2 shows a plan view of acompartment base 4 as a first exemplary embodiment for a chilled goods support according to the invention. The compartment base is substantially constructed of aplate 10 made of safety glass having aframe 11 made of plastic injection moulded on in one piece around its circumference. In each case, aweb 12 and apin 13 project in a manner known per se from the lateral flanks of theframe 11, which serve to support the compartment base in grooves on theside walls 3 of the chilled compartment so that it can be withdrawn. Afront edge 14 of theframe 11 facing the door is sloping similar to a desk, where a liquid crystaltemperature display unit 9 is attached to the slopingsurface 15 of thefront edge 14. In this embodiment thedisplay 9 is divided bywebs 16 into a plurality offields 17, each being enclosed between two films and having a liquid crystal composition with a different colour transition temperature. Usually temperature-sensitive liquid crystal compositions appear green at their transition temperature, reddish thereunder and blue thereover. A user can determine the temperature of a region at a glance from the position of thegreen field 17 in the arrangement of thedisplay 9 or from the number of reddish or blue fields and from this can rapidly identify the suitability of a region for storing a certain type of chilled goods such as vegetables, milk products or meat goods. -
FIG. 4 shows a plan view of a second embodiment of acompartment base 4 where thetemperature display 9 has a continuous display zone whose liquid crystal composition varies from left to right so that, depending on the temperature to which the display is exposed, aboundary 19 between the blue and reddish region moves continuously over the display zone with temperature. Since in this embodiment, the display zone is not divided into individual fields, a user cannot easily deduce the temperature or the suitability of aregion 5 for a certain type of chilled goods from the number of fields in a certain colour; instead, theframe 11 is provided with a row ofreference marks 20 next to thetemperature display 9 so that a user can determine the suitability of the relevant region for a certain cooling device from the position of theboundary 19 in relation toreference marks 20. - Naturally, as shown in
FIG. 4 , thetemperature display 9 can also be provided with a scale, for example in the form of numeral-shaped windows 21 in a non-transparent cover layer through which the liquid crystal material is visible and which allow a user to quantitatively read off the temperature of therelevant region 5. -
FIG. 5 shows a schematic section through thefront edge 14 of theframe 11 and theglass plate 10 enclosed thereby along the line V-V fromFIG. 4 , where it is understood that a corresponding section in the embodiments inFIGS. 2 and 3 could have the same shape. Thefront edge 14 which is moulded onto theglass plate 10 encloses this in a closed material fashion. Thetemperature display 9 is let into anindentation 22 on the upwardly slopingsurface 15 of thefront edge 14. It is attached to the inner side of arigid disk 23, e.g. made of transparent plastic, which is enclosed in the material by moulding with the material of theframe 11 along its edges, thus holding thedisplay 9 securely and protected. -
FIGS. 6 and 7 show a fourth embodiment of acompartment base 4 in a partial plan view or in a section along the line VII-VII fromFIG. 6 . As in the case inFIG. 2 , the compartment base has aglass plate 10 which in the present case is not moulded with a frame but an extruded profile is placed on its front and rear (not shown) edges as a frame element. The profile forming thefront edge 14 has agroove 24 on its rear side facing theglass plate 10, into which theglass plate 10 is inserted, wherein a rubber or foam-material strip 25 which is affixed to alower leg 26 of thefront edge 14 bordering thegroove 24, is elastically compressed so that it presses the upper side of theglass plate 10 flat against the opposite side of theupper leg 27. The large-area contact allows good heat transfer between theglass plate 10 and thefront edge 14 so that theglass plate 10 can also serve as a thermal buffer for the liquid crystaltemperature display unit 9 which is glued to the slopingsurface 15 of thefront edge 14. - In this fourth exemplary embodiment the
temperature display 9 is the same as in the third exemplary embodiment since it is comparatively laborious to construct features such as thewebs 12 or thereference marks 20 which make it easier to read thedisplay 9 in an extruded profile.
