Abstract

The invention refers to a fluid foaming machine (100) for producing foam comprising a fluid container (30) where the fluid is arranged, and a foaming device (40) through which fluid flows and is heated and/or foamed, the machine (100) further comprising at least a cooling unit configured to maintain permanently refrigerated both the fluid container (30) and the foaming device (40) during fluid preparation and during stand-by of the machine (100).

First claim

The invention claimed is:

1. A fluid foaming machine for producing foam, the fluid foaming machine comprising a fluid container where fluid is contained, and a foaming device through which the fluid flows and the fluid is heated and/or foamed,
the fluid foaming machine comprising at least two distinct cooling units configured to maintain permanently refrigerated both the fluid container and the foaming device during fluid preparation and during stand-by of the fluid foaming machine, the at least two distinct cooling units are configured to refrigerate the fluid container and the foaming device separately,
wherein a first cooling unit refrigerates a primary compartment where the fluid container is arranged, wherein the primary compartment comprises a first cooling block configured to cooperate with a cavity in the fluid container, and the primary compartment comprises cooling walls configured to refrigerate sides of the fluid container, and a second cooling unit refrigerates a second cooling block configured to contour and refrigerate the foaming device.

2. The fluid foaming machine according to claim 1 wherein the fluid container and the foaming device are removable from the fluid foaming machine.

3. The fluid foaming machine according to claim 1 comprising a top opening provided with an air entry and a steam entry configured to cooperate with corresponding air and steam entries in the foaming device when the top opening closes over the foaming device.

4. The fluid foaming machine according to claim 3 comprising at least one valve configured to control the air and/or steam entries in the top opening.

5. The fluid foaming machine according to claim 1 further comprising a heater configured to heat the fluid dispensed through the foaming device.

6. The fluid foaming machine according to claim 5 wherein the heater comprises a conduction and/or radiation and/or hot air and/or induction member.

7. A fluid foaming machine for producing foam, the fluid foaming machine comprising a fluid container where fluid is contained, and a foaming device through which the fluid flows and the fluid is heated and/or foamed,
the fluid foaming machine further comprising at least one cooling unit configured to maintain permanently refrigerated both the fluid container and the foaming device during fluid preparation and during stand-by of the fluid foaming machine, wherein the at least one cooling unit is configured to refrigerate a cooling block, the cooling block comprising an inner volume to receive the fluid container, and the cooling block comprising an insert part configured to receive the foaming device.

8. The fluid foaming machine according to claim 7 comprising two distinct cooling units configured to refrigerate the fluid container and the foaming device separately.

9. The fluid foaming machine according to claim 8 wherein a first cooling unit refrigerates a primary compartment where the fluid container is arranged, and a second cooling unit refrigerates a cooling block configured to contour and refrigerate the foaming device.

10. A fluid foaming machine for producing foam, the fluid foaming machine comprising a fluid container where the fluid is contained, and a foaming device through which the fluid flows and the fluid is heated and/or foamed,
the fluid foaming machine comprising at least one cooling unit configured to maintain permanently refrigerated both the fluid container and the foaming device during fluid preparation and during stand-by of the fluid foaming machine,
the fluid foaming machine comprising a foaming receiver at least partly shaped complementary to the foaming device so that the foaming device is tightened when arranged into the foaming receiver.

11. A fluid foaming machine for producing foam, the fluid foaming machine comprising a fluid container where fluid is contained, and a foaming device through which the fluid flows and the fluid is heated and/or foamed,
the fluid foaming machine comprising at least one cooling unit configured to maintain permanently refrigerated both the fluid container and the foaming device during fluid preparation and during stand-by of the fluid foaming machine, wherein the fluid container comprises a filling inlet through which the fluid can be inserted in the fluid container without removing the fluid container from the fluid foaming machine.

12. A fluid foaming machine for producing foam, the fluid foaming machine comprising a fluid container where fluid is contained, and a foaming device through which the fluid flows and the fluid is heated and/or foamed,
the fluid foaming machine comprising at least one cooling unit configured to maintain permanently refrigerated both the fluid container and the foaming device during fluid preparation and during stand-by of the fluid foaming machine, wherein the fluid container comprises an integrated guide part configured to receive the foaming device.
