Household cooling appliance with specific external cooling of a sub-unit of the ice maker
A household cooling appliance includes an outer housing, a cooling compartment in the outer housing, and an ice maker unit, which is arranged in the cooling compartment. The ice maker unit includes a first sub-unit, which is configured for making crushed ice from ice form elements. The first sub-unit has a housing. A crusher device for crushing the ice form element is arranged in the housing. A cooling device cools the first sub-unit with cold air. The cooling device has an air duct. The air duct ends at the housing of the first sub-unit and at least partly is configured to extend along an outer side of the housing so that the cold air for cooling the housing flows along the outer side of the housing.

a cooling device for cooling the first sub-unit with cold air,
wherein the cooling device comprises an air duct, wherein the air duct ends at the housing of the first sub-unit and at least partly is configured to extend along an outer side of the housing so that the cold air for cooling the housing flows along the outer side of the housing, and the cold air, upon flowing around the housing, is conducted back into the second sub-unit.
2. The household cooling appliance according to claim 1 , wherein the air duct viewed in the height direction of the housing is arranged to extend along a ceiling wall of the housing and the cold air flows along an outer side of the ceiling wall.
3. The household cooling appliance according to claim 1 , wherein the air duct viewed in a vertical direction of the housing is arranged to extend at least along one side wall of the housing and the cold air flows along an outer side of the side wall.
4. The household cooling appliance according to claim 1 , wherein the air duct viewed in the depth direction of the housing is arranged to extend at least along a front wall of the housing and the cold air flows along an outer side of the front wall.
5. The household cooling appliance according to claim 1 , wherein the air duct viewed in the height direction of the housing is arranged to extend at least along a bottom wall of the housing and the cold air flows along an outer side of the bottom wall.
6. The household cooling appliance according to claim 1 , wherein the air duct outside the housing is arranged in such a way that the cold air flows only outside the housing.
7. The household cooling appliance according to claim 1 , wherein the air duct upstream of the housing branches off the second sub-unit so that cold air is capable of being conducted from the second sub-unit via the air channel to the housing of the first sub-unit.
8. The household cooling appliance according to claim 1 , wherein
the household cooling appliance comprises an output unit for dispensing ice form elements or crushed ice, and
the household cooling appliance comprises an ice chute, which is connected with the first sub-unit and with the output unit and with which ice form elements or crushed ice is capable of being conducted from the first sub-unit to the output unit, wherein
the air duct ends at the ice chute and the ice chute is capable of being cooled with cold air in the air duct.
9. The household cooling appliance according to claim 8 , wherein the air duct ends in the ice chute so that the cold air can flow into the ice chute.
10. The household cooling appliance according to claim 8 , wherein the air duct ends at an outer side of the ice chute so that cold air can flow along the outer side of the ice chute.
11. The household cooling appliance according to claim 1 , wherein the flowing of the cold air in the air duct is effected by convection.
12. The household cooling appliance according to claim 1 , wherein the household cooling appliance comprises a ventilator, by which the flowing of cold air in the air duct is effected.
13. The household cooling appliance according to claim 12 , wherein the ventilator is arranged in the ice maker unit.
14. The household cooling appliance according to claim 12 , wherein the household cooling appliance comprises a freezer compartment, and the ventilator is arranged in the freezer compartment, wherein the freezer compartment is connected with a further air duct for conducting the cold air with the ice maker unit.
15. The household cooling appliance according to claim 1 , wherein the air duct downstream of the first sub-unit ends in the cooling compartment.
16. The household cooling appliance according to claim 1 , wherein
a freezer compartment of the household cooling appliance is arranged in the outer housing, and the freezer compartment outside the cooling compartment and viewed in a vertical direction of the household cooling appliance is arranged below the cooling compartment, and
the freezer compartment is capable of being closed at the front side by least one door of the household cooling appliance and the cooling compartment is capable of being closed on the front side by two separate further doors of the household cooling appliance, wherein the two doors for closing the cooling compartment viewed in the width direction of the household cooling appliance are arranged next to each other.
