<p>A water tank for heating water preferably in a vending machine for beverages comprises a feed-water inlet (2), a hot water outlet (3), as well as a heating member (4) for heating the water. The water tank (1) is divided into a heating section (21) including the hot water outlet (3) and the heating member (4), as well as a lime-precipitating section (22) including the feed-water inlet (2), said tank being divided by means of a partition (6). This partition (6) extends from one side (7) of the water tank immediately adjacent the surface of the water at maximum water level (10) and obliquely downwards towards the opposite side (12) of said water tank. Then the partition extends at a distance from the tank wall (12) downwards to the immediate vicinity of the bottom (14) of said water tank, whereby the heating section (21) is placed below the oblique portion (11) of the partition (6). An upper flow passage (18, 19) for water is provided between the heating section (21) and the lime-precipitating section (22) at the upper end of the oblique portion (11) of the partition (6), and a lower flow passage (28) for water is provided between the lime-precipitating section (22) and the heating section (21) at the lower rim of the partition (6).</p> |
