Definitions
- a beverage maker and a method for providing a chilled hot beverage are presented. It will be in the beverage maker and the
- a heat exchanger and a cooling device are used, the cooling device having an ice-water container filled with an ice-water mixture, which is fluidically connected to the heat exchanger.
- a pump is used which conveys cold water from the ice-water container into the heat exchanger via a cold water line and conveys water from the heat exchanger to the ice-water container via a supply line.
- beverage makers are required that can also produce cold beverages such as iced coffee and / or iced coffee in a quick and reliable manner without the cold beverage due to If the temperature is too high, it must be diluted too much when it is made available (e.g. by melting ice in the cold drink provided).
- the dispensing temperature of such cold drinks or ice drinks is well below the ambient temperature, preferably 15 ° C or below.
- a very simple method is to let freshly brewed coffee cool in a vessel, preferably in a chilled environment such as a refrigerator or cold room.
- Another method consists in cooling a brewed coffee (e.g. in the form of a coffee concentrate) immediately after brewing by adding cold water and ice and diluting it to drinking strength.
- a brewed coffee e.g. in the form of a coffee concentrate
- Another method is to pass the freshly brewed coffee through a heat exchanger in order to achieve rapid cooling as it passes through.
- the heat exchangers are usually actively cooled (i.e. using electricity) using compressor units or Peltier elements.
- Passive cooling by means of a cold water counterflow is also known.
- EP 3 125 730 A1 discloses an energy-saving method for preparing a freshly brewed cold coffee drink, in which a hot coffee drink is brought into thermal contact with a stream of cold water.
- EP 2 268 175 Al discloses a method for producing a Kaltge drink in which a hot drink without direct addition of coolants in the dem- the same beverage preparation device is cooled by means of a cooling device, the cooling device being implemented with an active cooling unit (ie a cooling unit that requires electrical power), such as a compressor, an absorber or a Peltier element arrangement.
- an active cooling unit ie a cooling unit that requires electrical power
- EP 2 278 240 A2 discloses a device that contains a coffee cooler and an active cooling unit, the coffee cooler being designed as a heat exchanger and the cooling unit causing active cooling (ie cooling that requires electrical power) by means of a cooling circuit that includes an evaporator and has a compressor.
- the disadvantage of cooling through the environment (air) is that long waiting times are required to cool the drink to the desired temperature, which can affect the taste of the drink and mean long waiting times for the user before the drink can be enjoyed.
- cooling capacity depends on the coldness of the inlet water. Since the inlet water has a relatively high temperature in many regions of the world and the temperature of the inlet water can fluctuate between the seasons, the cooling capacity achieved is relatively low and not constant.
- the disadvantage of cooling using active cooling units is that the equipment required to provide the beverage maker is very high. For example, when using evaporable organic refrigerants, a compressor must be installed in the beverage maker. Furthermore, beverage makers with active cooling units have a high energy consumption for active cooling.
- the object of the present invention was to provide a beverage maker and a method for providing a cooled hot Provide drink that do not have the disadvantages of the prior art.
- the beverage maker or the method should enable a hot beverage to be cooled quickly with a constant and high cooling capacity with little equipment and with minimal energy consumption.
- a beverage maker with a cooling device for providing a cooled hot beverage comprising a) a brewing unit for preparing a hot beverage; b) a beverage outlet, c) a beverage line which fluidly connects the brewing unit with the beverage outlet; d) a heat exchanger which contains the beverage line and a Kaltwasserlei device, wherein the cold water line and beverage line in the heat exchanger are not fluid-conducting, but are thermally connected; characterized in that the beverage maker comprises a cooling device which has an ice-water container filled with an ice-water mixture, which is fluidly connected to the heat exchanger via the cold water line, and the beverage maker comprises a pump which is configured for this purpose To convey cold water via the cold water line from the ice-water container into the heat exchanger and to convey water via a supply line from the heat exchanger to the ice-water container.
- the hot beverage (passively) brewed on the brewing unit can be moved by gravity from the brewing unit in the direction of the beverage outlet and / or actively moved by the brewing unit in the direction of the beverage outlet by means of a pump of the beverage maker (e.g. an espresso pump).
- a pump of the beverage maker e.g. an espresso pump
- the pump of the cold water circuit conveys the cold water from the ice-water tank through the heat exchanger and back to the ice-water Container.
- the refluxing heated water is cooled again in the ice-water container by the melting ice.
- the heat of fusion of the water during the phase transition is used to cool the coffee in the heat exchanger.
- thermodynamics it is known that when there is a change in the aggregate state, in this case the phase transition from solid to liquid in ice water, heat energy can be added to the system without the temperature of the medium being increased.
- the advantage here is that water has a relatively high melting enthalpy of 334 kJ / kg. Once all of the ice in the container has melted, the temperature of the water in the cooling circuit rises (approx. 4.19 kJ / (kg K)). This can be recognized by a cooling water temperature sensor in the cold water circuit. If the temperature rises above a certain threshold value, some of the cooling water can be drained off and the container filled with ice in order to keep the cooling capacity constant. The filling with ice (e.g.
- the beverage maker can do without an active cooling unit (i.e. without a cooling unit that uses electricity for cooling) and thus uses less energy than state-of-the-art beverage makers that use active cooling units, e.g. cooling units based on evaporation and condensation of organic refrigerants and / or cooling units with Peltier elements.
- active cooling units e.g. cooling units based on evaporation and condensation of organic refrigerants and / or cooling units with Peltier elements.
- the beverage maker according to the invention is more environmentally friendly since it does not require any organic refrigerants, the release of which into the environment is known to increase the greenhouse effect.

- the beverage maker in particular the ice-water container, has a filter for retaining ice particles, the filter preferably being arranged at a transition from the ice-water container to the cold water pipe or in the cold water pipe.
- the advantage of such a filter is that ice and ice particles that are present in the ice-water container, and possibly dirt particles that could get into the ice-water container over time, do not pass through the cold water line to the pump of the cold water circuit and thus cannot damage the pump.
- the filter advantageously has a mesh size (ie openings with a size) in the range from 30 ⁇ m to 500 ⁇ m.
- the ice-water container contains the ice-water mixture preferably in a volume that is at least as large as the volume within the Kaltwas water line and supply line.

- the hot water heater downstream of the brewing unit can fluidically communicate with the Be connected beverage line, preferably at one point of the beverage line upstream of the heat exchanger. This case is advantageous if a cold drink is provided that is first brewed as a hot concentrate and then diluted to drinking strength with hot water before cooling in the heat exchanger.
- the dilution with hot water before cooling does require a higher cooling energy or cooling capacity in the heat exchanger, but it can ensure that the provision of a contaminated drink can be avoided even in locations where a supply of germ-free cold water is not ensured.
- this fluidic connection of the hot water heater to the beverage line is also advantageous when a hot beverage is provided, because in this case a concentrated hot beverage coming from the brewing group can be diluted to drinking strength and the heat exchanger can be bypassed via a switching valve, so that no cooling of the hot beverage takes place ("bypass").

- the pump 9 is configured to convey cold water via the cold water line 6 from the ice-water container 8 to the heat exchanger 5 and to promote water via a feed line from the heat exchanger 5 to the ice-water container 8.
- the beverage maker also comprises a hot water maker 10, which is fluidly connected to the beverage line 3 via a valve 11, and a cold water supply 10 ' which is fluidically connected to the beverage line 3 via a valve 11 '.
- the beverage maker comprises a switching valve 14 upstream of the heat exchanger 5, with which the beverage line 3 can be fluidically connected to a beverage bypass line 15 which opens into the beverage line 3 downstream of the heat exchanger.
- the switching valve 14 serves to bypass a flow of hot drink through the heat exchanger 5 (“bypass”) so that the drink provided by the brewing unit 1 is not cooled by the heat exchanger 5.
