Abstract
The invention relates to drink dispensers, particularly such dispensers in which the drink is stored in readily mixed or premixed form in a reservoir. The invention provides an improved heat or cold transmission for such dispensers. The thermal conduction between the bottom of the reservoir and a cooling plate provided in the base is improved by a freezing liquid introduced between the bottom and the cooling plate. The thermal conduction is particularly homogenized and improved by providing a cellulose layer between the reservoir bottom and the cooling plate, the layer taking up or absorbing the liquid.
Claims13
A dispenser for drink comprising:
- a base having a low-temperature conveyance section therein;
- a cooling apparatus operatively associated with the low-temperature conveyance section;
- means for storing the drink, said storing means mounted on the base and operatively connected to the low-temperature conveyance section, the storing means having a bottom with a thermally conductive portion;
- a liquid which freezes in operation, the liquid being introducible between the low-temperature conveyance section and the thermally conductive portion;
- and,
- an absorbent layer between said low-temperature conveyance section and said thermally conductive portion, said liquid being distributable free from air bubbles within said layer.
In a drink dispenser having a cooling surface and a removable drink reservoir with a thermally conductive bottom, a process for improving thermal conduction between the cooling surface and the bottom comprising the steps of
- introducing a liquid between said bottom and said cooling surface;
- providing an absorbent cellulose layer, wherein said liquid is storable in said absorbent layer;
- introducing said liquid into said layer;
- and
- freezing said liquid to constitute a thermal conduction layer, whereby said absorbent layer and said frozen liquid together homogenizing and improving said thermal conduction.
In a drink dispenser having a cooling surface and a drink reservoir with a thermally conductive bottom, a process for improving thermal conduction between the cooling surface and the bottom comprising the steps of
- introducing a liquid between said bottom and said cooling surface to constitute a thermal conduction layer and freezing said liquid;
- providing an absorbent cellulose layer, wherein said liquid is storable in said absorbent layer;
- introducing said liquid into said layer, said absorbent layer and said frozen liquid together homogenizing and improving said thermal conduction;
- compressing said absorbent layer by means of clamping elements on a base of the drink dispenser and flanges on the reservoir of the drink dispenser engaged by said clamping elements.
