Problems solved by technology

[0009] 3) The outside temperature of the boiler (when not properly protected) is the same as the inside temperature, so there is a risk of burns
[0014] 3) The external temperature of the heat exchanger (when not properly protected) is very high and there is a risk of burns
[0016] In addition to the disadvantages of the devices presented in the above documents, this open heat exchanger has the disadvantage of not being able to dispense water volumes greater than 100ml without deteriorating performance

Embodiment Construction

[0028] The heater according to the invention comprises a first chamber and a second chamber, coaxial with each other, closed at the ends by top and bottom covers and opened at the base by The openings or holes are located away from the water inlet and outlet fittings on the outer wall of the heater and on the top cover, respectively.

[0029] The first chamber is also called "outer chamber" and the second chamber is also called "inner chamber"; inside this second chamber at least one resistor or resistor is arranged.

[0030] Water flows into the heat exchanger interior through the inlet fitting located away from the opening connecting the first and second chambers together, and through said opening into the second chamber until height check (levelcheck) (the height checker interrupts the flow of water), and the water is heated by at least one resistor arranged inside the second chamber, and distributed through the outlet pipe connection near the inlet pipe connection at the p...

Abstract

The present invention relates to a water heating system (part number lacubucci HF Aerospace AS0012480) for beverage dispensing machines. The heater has a double system: a pre-chamber, preferably of the spirally wound type, for pre-heating the water along a predefined path, and a chamber which is always full of water heated with resistors making direct contact with the water (or in some cases with a protection jacket) for maximizing the efficiency.

Description

technical field [0001] The invention relates to a device for heating water. In particular, the device according to the invention (hereinafter also referred to as "heater" or "heat exchanger", or simply "exchanger") may be used in machines for dispensing beverages such as coffee, tea or water. The unit is designed for use in the aviation sector, but can be used in other sectors as well. [0002] The heater has a dual system: a preparation chamber, preferably of the helically wound type, for preheating hot water along a predetermined path; Sheath) resistor to heat the chamber in order to maximize efficiency. Background technique [0003] Other heating systems for beverage dispensing machines are known. The main problems to be solved are: [0004] a) lack of space, since the devices housing them have particularly small dimensions; [0005] b) Strict standards and technical elements, taking into account the field of application. [0006] Document EP1157647 describes a coff...
