1Productivity
If microwave heating devices are used for volumetric heating, then heating efficiency is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces the complex microwave heating system (magnetron, waveguide, high voltage power source) with a simpler infrared heating system using ceramic heating elements that emit infrared radiation directly to heat the liquid volumetrically, maintaining heating efficiency while reducing device complexity

Function Achieved in This Case
The solution provides a cost-effective, space-efficient, and efficient heating method with reduced calcium residue and shorter heat-up times, suitable for beverage preparation machines, achieving high energy absorption and uniform temperature distribution.
Implementation Method 1
an emission source (1) designed for emitting electromagnetic radiation, preferably in the infrared and/or ultra violet spectrum, to transfer the energy to a liquid (3)
Implementation Method 2
Many molecules (such as those of water) are electric dipoles, meaning that they have a partial positive charge at one end and a partial negative charge at the other, and therefore rotate as they try to align themselves with the alternating electric field of the microwaves. Rotating molecules hit other molecules and put them into motion, thus dispersing energy. This energy, when dispersed as molecular vibration in solids and liquids (i.e., as both potential energy and kinetic energy of atoms), is heat.
Implementation Method 3
an isolation means (4) essentially transparent to the electromagnetic radiation in the emitted spectrum, and designed to electrically and/or thermally isolate the emission source from the liquid
