Problems solved by technology

The heater is usually installed inside the beverage dispenser. Its design is simple and inexpensive. Soldering, assembly, coupling, etc. between the heater parts may fail under continuous vibration. The design of the water heater must take into account Such risks often lead to increased production costs
[0010] Continuously vibrating the water heater at high frequency for a long period of time may cause mechanical failure, and this method of descaling is very power-consuming

Embodiment Construction

[0046] figure 1 A flowchart of the method according to the present invention is shown to remove or reduce scale deposits inside the beverage dispenser of the water heater. The method includes the step of inducing high-energy ultrasonic vibration of the water heater, by charging the ultrasonic generator, the ultrasonic generator is directly or indirectly connected to the same heater. For example, the water heater supplies hot water to the beverage dispenser to prepare coffee, chocolate, cappuccino, tea... etc.

[0047] Different from the method disclosed in the prior art, in the present invention, the ultrasonic vibration is caused discontinuously in a short discrete time interval, and it is preferable to vibrate at a frequency different from the natural frequency of the water heater. The resonance of the heater can be avoided to prevent excess mechanical pressure. in figure 1 In the evaluation of the natural frequency of the heater can be optionally added.

[0048] Vibration is...

Abstract

The present invention relates to a method and an apparatus (1) for removing, or substantially reducing, the limescale deposits within a water heater (5) of a beverage dispensing machine, by inducing ultrasonic vibrations through an ultrasonic generator (2). Advantageously the step of inducing ultrasonic vibrations is implemented discontinuously at high energy levels.

Description

Technical field [0001] The present invention relates to a method and device for treating scale deposits of water heaters in beverage dispensers. Background technique [0002] It is well known that the internal surface of the water heater that contacts the water often produces scale. In fact, heating the water causes the ionization of the decomposed salt and causes the deposition of a layer of scale on the surface of the water heater. This increase in scale causes hard deposits that are difficult to remove and are harmful to the operation of the water heater and the water heater delivery pipe. Such deposits reduce the efficiency of heat exchange between the heater and the hot surface of the water, thus causing a waste of energy. And the increase of excess scale will cause the blockage of the delivery pipe. [0003] It has been proposed that different devices use vibration to reduce the accumulation of scale in the water heater, such as the accumulation of scale in a kettle, rapid ...
