Boiler for a machine for making hot beverages

摘要

A boiler for use in a machine for making hot beverages includes a heat diffuser with a first wall destined to be placed in contact with the liquid to be heated and a second wall opposite first wall, heating element consisting of at least one serigraphed or photo-engraved resistance arranged on second wall of heat diffuser and defining a pattern formed of at least on resistive track, a body which with first wall of heat diffuser defines a heating chamber inside which the liquid is to be heated. It also includes a bearing element shaped to bear on second wall of heat diffuser on at least one zone, the resistive track(s) being arranged on either side of the zone so that the bearing element receives at least part of the force transmitted by the liquid to heat diffuser and resulting from the pressurizing of liquid in the heating chamber.

主权项

1. Boiler for use on a machine for making hot beverages, comprising:
a heat diffuser comprising a first wall configured to be placed in contact with a liquid to be heated and a second wall opposite the first wall; a heater comprising at least one serigraphed or photo-engraved resistance arranged on the second wall of the heat diffuser and forming a pattern comprising one or more resistive track; a body, which with the first wall of the heat diffuser, defines a heating chamber inside which the liquid is to be heated; a support joined to the body; and a bearing, arranged to bear on at least one zone of the second wall of the heat diffuser, the one or more resistive track being arranged on each side of the at least one zone so that said at least one zone which bears the bearing is arranged between at least two parts of the pattern defined by the one or more resistive track, and the bearing being attached to the support or being integral with the support so that the bearing absorbs at least part of the force transmitted by the liquid to the heat diffuser and resulting from pressurizing of the liquid being heated in the heating chamber, and the bearing transfers at least part of said force to the support and to the body to which the support is joined.
