Definitions

  • the invention relates to a device for temperature control of liquids and in particular a special cooling device for cooling liquids with a cooling element.
  • Cooling devices are known, for example, for ice machines. These are cooling elements that can be inserted into a device to cool liquids such as ice cream. Such cooling elements, in particular with a liquid with antifreeze, are also known as cooling batteries for cool bags.
  • EIS 4,599,872 and WO 2018/066998 A1 show a cooling device for cooling liquids, which has a liquid channel with a channel inlet and a channel outlet.
  • these devices are complex to manufacture and difficult to clean.
  • the invention is based on the object of developing such a device. This object is achieved with a device having the features of claim 1 patent. Advantageous further developments are the subject of the subclaims.
  • the “Coolbank” is a mobile cold storage device that releases its cold, in particular to drinks, as required, in order to cool them.
  • the memory can also store heat in order to transfer it to the liquid.
  • baby milk must be heated to a certain temperature as precisely as possible and overheating must be avoided at all costs. This is easy to achieve with the heat accumulator, which is also available independently of a power connection and makes it possible to heat any liquid, in particular baby milk or another drink.
  • the “Coolbank” is preferably an insulated container that can be filled with an anti-freeze liquid so that it can be cooled below 0 ° C.
  • This “Coolbank” can be placed in a freezer as a single component in order to be cooled down there as a cooling element, or the entire cooling device can be placed in the freezer to cool down. Accordingly, the memory can also be heated alone or together with the device. However, if the entire cooling device consists of EPP, heating is not advantageous. It is therefore particularly advantageous if the preferably spiral-shaped cold pack is cooled from finally.
  • the channel is limited by two components. This makes the manufacture and cleaning of the channel much easier.
  • a simple embodiment provides that an elastic hose, such as a silicone hose, is pulled over the inner component, which acts as a tempering element.
  • a pipe is used as a channel in the prior art
  • preferably half-pipe shells or milled-out portions in a component that are covered by a further component are used. This creates a channel from a channel inlet to a channel outlet, which makes it possible to use a storage element to cool or heat liquid flowing in the channel.
  • the storage element can be filled with a liquid that acts as a cooling liquid.
  • a liquid that acts as a cooling liquid can also be a material with a high heat capacity, such as, for example, a stone such as a granite.
  • each limit approximately half of the channel means that a U-shaped cutout, which is covered by a surface of a further component, also represents a device in which the components each delimit approximately half of the channel.
  • This has the advantage that, in particular for cleaning, the duct parts are easily accessible and therefore easy to clean, regardless of whether they are concave or flat. It is particularly advantageous if the channel in one component has a concave surface which is delimited by a planar surface of the further component.
  • the channel has depressions for forming the channel and cooperates with a planar surface of the other component in order to delimit the channel.
  • the channel then has a U-shaped shape in cross section, the curved larger surface of the channel preferably being arranged closer to the cooling element. As a result, a larger surface area of the channel is connected to the cooling element.
  • a particularly simple structure results from the fact that the components are conical. This makes it possible to plug one part into the other part and to form a channel between the components when plugged together.
  • a fit between the components can be designed in such a way that a seal is created between the components and the components can nevertheless also be taken apart again in order to be able to clean the components more easily.
  • An alternative embodiment provides that the components are cylindrical and are plugged into one another.
  • the filling of the channel is made easier if one of the components has an upper side with an opening and a connection to the channel.
  • a second use can be achieved in that one component is a cup. This component can either be used as a drinking cup or only serve as a radially outer component with its cup shape.
  • the channel be at least partially spiral-shaped.
  • the channel have a plurality of sub-channels flowing through them in parallel.
  • the partial channels through which the flow passes in parallel can also be designed in a spiral shape.
  • a better seal between the components for forming the channel can be achieved in that at least one component has a lip seal which is preferably formed in one piece with the component and which interacts with the other component.
  • the channel inlet has a filling funnel. There you can collect liquid, which then slowly flows through the channel from the channel inlet to the channel outlet.
  • the liquid channel surrounds the cooling element. This makes it possible, for example, to provide the cooling element in a first component and to form the channel radially outside the cooling element or at the edge of the cooling element, which is thereby located radially outside the cooling element or is guided along the outer surface of the cooling element.
  • the liquid channel can also be arranged radially inside the cooling element. That is to say, cooling elements can be arranged radially inside the channel and / or radially outside the channel.
  • a base be adjacent to one of the components.
  • This stand can be a have ring-shaped foot element or several foot elements which make it possible, for example, to place the device on a table top in such a way that a vessel, such as a drinking cup in particular, can be arranged between the channel outlet and the table top.
  • the base delimits at least one of the components and is arranged such that it can be displaced relative to the components delimiting the channel.
