Abstract
The invention relates to a kitchen appliance (1), in particular a mixer, comprising a housing (2), a heat source (3), in particular a motor or a device electronics, and a cooling device (4). To avoid contamination of the kitchen appliance (1) and to attain an improved sound absorption, it is proposed for the heat source (3) to be connected to a heat exchanger element (5) of the cooling device (4), which is arranged separately from this heat source (3) and which forms a partial area of an outer surface of the housing (2), wherein the heat exchanger element (5) is embodied in such a manner that it can emit heat, which is to be discharged from the heat source (3), into the environment by means of natural convection
Claims8
1:
- A kitchen appliance (1), in particular a mixer, comprising a housing (2), a heat source (3), in particular a motor or a device electronics, and a cooling device (4), wherein the heat source (3) is connected to a heat exchanger element (5) of the cooling device (4), which is arranged separately from this heat source (3) and which forms a partial area of an outer surface of the housing (2), wherein the heat exchanger element (5) is embodied in such a manner that it can emit heat, which is to be discharged from the heat source (3), into the environment by means of natural convection.
2:
- The kitchen appliance (1) according to claim 1, wherein the heat exchanger element (5) has a metal plate.
3:
- The kitchen appliance (1) according to claim 1, wherein the heat exchanger element (5) is embodied in a housing-shaped manner, in particular as a cup, which is open on one side, wherein the heat source (3) is at least partially surrounded by the housing-shaped heat exchanger element (5).
4:
- The kitchen appliance (1) according to claim 1, wherein the heat source (3) is connected to the heat exchanger element (5) by means of a heat-transferring element (6), in particular a heat-conducting element or a heat pipe.
5:
- The kitchen appliance (1) according to claim 1, wherein the cooling device (4) is an absorption refrigeration comprising an evaporator (7), a liquefier (8) and at least one heating element (9), wherein the evaporator (7) and the liquefier (8) are parts of the heat exchanger element (5).
6:
- The kitchen appliance (1) according to claim 5, wherein the heating element (9) is a separate element, which is independent from the heat source (3).
7:
- The kitchen appliance (1) according to claim 5, wherein the liquefier (8) and/or the evaporator (7) is embodied in a tubular manner.
8:
- The kitchen appliance (1) according to claim 5, wherein the evaporator (7) is assigned to a vessel (10) of the kitchen appliance (1) in such a manner that food, which is contained in the vessel (10), can be cooled.
