other Embodiment approach

[0081] Other embodiments and changes in cross-section with reference to those described above are generally possible through changes in the width and / or depth of the duct 1 .

[0082] Figures 15 to 18 The implementation shows an example where changes in width and depth are associated. In addition to acting on these two dimensions to optimize changes in fluid flow regimes, this dual change can also be used to limit or keep constant the size of the cross-section along the pipe 1 .

[0083] exist Figure 16 and 17 Above, wide regions 17 and deep regions 18 alternate along the length of the pipe 1 . Preferably, the wide regions 17 are also shallower than the deep regions 18 , and vice versa with regard to width. Thus, despite shape variations, similar or identical cross-sectional dimensions may be implemented.

[0084] According to one possibility, the transition between areas 17 and 18 is abrupt.

[0085] But when Figures 15 to 18 In the case shown, by utilizing the tran...

Abstract

The invention relates to a fluid circulation duct (1) for the heating device of a domestic appliance, characterised in that the fluid circulation duct thereof comprises means for generating turbulence in the fluid flowing in the inner volume (2) thereof. The invention can be used in domestic appliances including such a heating system.

Description

technical field [0001] The present invention relates to fluid communication conduits. The present invention is especially suitable for heating devices of household electrical appliances. This includes in particular beverage preparation machines which prepare beverages by steeping of materials such as ground coffee or finely ground tea leaves or by dissolution of especially granular materials. A preferred application is the implementation of coffee machines for espresso type coffee. Background technique [0002] In the illustrative field of coffee machines, the fluid, in this case water, needs to be heated to such an extent that an optimum extraction of the aromatic substances of the ground coffee is guaranteed. A device known as a boiler is provided for this purpose and usually has a supply line for the water to be heated and a heating element, in particular in the form of an electric resistance. Water may transition, for example, from an input temperature of 20 degrees C...
