Abstract: A liquid preparation device intended for simultaneous heating and cooling of a liquid, said device including a raw liquid container, a thermoelectric converter, a control unit, a flow separation unit and a liquid preparation container being divided into a liquid heating section and a liquid cooling section, each section having a respective impermeable barrier adjacent to said thermoelectric converter. A liquid level control device is provided on the outer side of upper walls of the liquid heating section and of the liquid cooling section and in the form of a tray having a liquid level sensor on the bottom. An air exhaust is formed by two openings disposed symmetrically above the heating and cooling sections. A control unit contains a controller and, connected to it, said liquid level control device, disposed in the liquid preparation container.
