  • the heating method and the device of another conventional beverage in FIG. 2 rely on a higher power heating guide to instantaneously heat the heating channel 92, which is liable to cause an instantaneous power overload, thereby increasing the limitation of use margin and Dangerous, and still difficult to access the beverage heated to a predetermined temperature in a very short time
  • the invention shown in FIG. 3 relies on the control unit 3 to control the heating unit 24 of the heat storage unit 2 to be preheated and maintained.
  • the heat storage portion 2 is not lower than a predetermined temperature to pre-store heat energy in the heat storage portion 2, thereby enabling the present invention to rapidly heat the liquid flowing through the heat storage portion 2 to a predetermined temperature, which can be reduced. Waste of energy and heating time.

Abstract

Cette invention concerne une méthode et un dispositif de chauffage des boissons. La méthode consiste à chauffer une zone de stockage de la chaleur à une température prédéterminée afin de stocker la chaleur en envoyant le liquide à une température relativement faible vers la zone de stockage par un conduit. Le passage du liquide à travers la zone de stockage de la chaleur a pour effet de chauffer le liquide. La méthode consiste également à stocker le liquide à une température relativement faible avant de le chauffer puis de l'évacuer une fois qu'il est chaud. Le dispositif comprend une unité d'application du liquide, une zone de stockage de la chaleur, un interrupteur d'application du liquide, une unité de commande et un tuyau d'application. L'unité d'application du liquide est reliée au tuyau de chauffage par le tuyau d'application. Le tuyau de chauffage est situé dans la zone de stockage de la chaleur. Cette dernière sert à préstocker l'énergie de chauffage et elle est maintenue à une température prédéterminée. L'unité de commande est dotée d'au moins un capteur de température qui permet de détecter la température dans la zone de stockage de la chaleur. L'interrupteur d'application du liquide commande l'ouverture et la fermeture du tuyau d'application et guide le liquide qui setrouve à une température relativement basse dans la zone de stockage de la chaleur pour faire chauffer le liquide via le tuyau d'application.
