Problems solved by technology

In known devices, the very small air nozzle will get dirty quickly, since it is mounted directly at the injector, so that contamination by milk or milk froth will occur
[0005] Also, at the end of milk froth generation, there is an intense and uncontrolled after-dripping of milk froth until the heater no longer produces steam

Embodiment Construction

[0029] The machine is connected by a pipe 1 to a water tank or storage tank, enabling a supply of fresh water through the pipe 1 . Fresh water is sucked in by means of a pump 2 integrated in the pipeline and then pumped into an electric heater 3, which is, for example, an electric instant water heater. In the heater 3 , preferably water vapor is generated, which is then conveyed to the mixing device 4 through the respective pipes. This mixing device is connected to the milk storage container via a pipe 5 so that milk can be sucked into the mixing device 4 through the pipe 5 . In addition, the mixing device 4 comprises a port for feeding air, so that the supplied milk mixed with water vapor and air leaves as foam at the dispensing opening of the mixing device and discharges into the container 6 .

[0030] According to the invention, a switching valve 7 is inserted between the heater 3 and the mixing device 4 , which connects the outlet of the heater 3 to the inlet of the mixin...

Abstract

The invention relates to an electric machine for preparing the beverages. In order to provide an electric machine for preparing beverages comprising a pump (2) for feeding fresh water, a heater (3) for heating the fresh water, a device for feeding milk, a device for feeding air, a mixing device (4) for mixing hot water, water vapor, milk and / or air, as well as a device for dispensing the mixture to a container (6), the mixing device (4) being connected to the water vapor or hot water outlet of the heater (3), and an air supply conduit and a milk supply conduit (5) leading into the mixing device (4), wherein strong and uncontrolled pre- and after--dropping during the milk foam production is prevented, it is proposed that a switching valve (7) is interposed between heater (3) and mixing device (4), said switching valve connecting in a first switching position the exit of the heater (3) with the mixing device (4); and in a second switching position the exit of the heater (3) with a conduit (8) that leads to a second outlet (9).

Description

technical field [0001] The invention relates to an electrical machine for preparing beverages, comprising: a pump for feeding fresh water, a heater for heating fresh water, means for feeding milk, means for feeding air, for mixing Mixing means for hot water, steam, milk and / or air, and means for dispensing the mixture into containers, the mixing means connected to the steam or hot water outlet of the heater, and the air supply line and the milk supply line leading to the mixing device. Background technique [0002] Such machines for preparing beverages are known in the prior art. [0003] In prior art machines for preparing beverages, milk froth is produced by means of an electric heater (for example, by means of an instant water heater); water vapor is produced by pumping intermittently with a pump feeding fresh water . This water vapor is supplied to a mixing device, such as an injector. The eductor is connected to a kind of pipe leading to a container with milk. Thro...
