Embodiment Construction

[0022] figure 1 and figure 2 The liquid heat reservoir 2 shown is part of a hot water generator or boiler and contains an electric heating body 4 whose electrical terminals 4-1 and 4-2 pass watertightly through a flange 6 The flange 6 is fitted watertight in a hole 8 in a bottom wall 10 of the container 2.

[0023] The heat storage container 2 consists of a container lower part 12 and a container upper part 14, which are connected to each other in a watertight manner on a parting surface 16 and are each produced by injection molding, for example, from metal or preferably from plastic. A fresh water supply line 20 extends through the container roof wall 18 almost as far as the bottom wall 10 for supplying fresh, cold water on a common water pipe network. The hot water access pipe 24 passes through the container roof wall 18 only to reach immediately below the container roof wall 18 . By opening a cold water switch, fresh water is introduced into the container mouth through ...

Abstract

The hot water tank of a domestic appliance, e.g. a boiler (2), has a deep and straight holder (40) in the tank wall (10) to take a thermostat (42). A straight and longitudinal gap (50) is formed in the wall (46) of the opening to stabilize the pressure injection molding tool used to form the opening.

Description

technical field [0001] The present invention relates to a liquid heat storage container of a hot water generator. Background technique [0002] German utility model patent G 82 09 111.0 U1 has pointed out a kind of liquid heat accumulator, it has a storage container made of a material with good heat conduction, such as steel, and is welded on the outer surface of the container with a steel Protective tube. Together, these are surrounded by a kind of insulating jacket. [0003] DE-AS 1 259 902 discloses a temperature sensor in a recess on the outer side of a steam boiler tube. The recess is V-shaped in cross section. A temperature sensor in the recess can be welded to the pipe and / or covered by a steel cover welded to the water pipe. [0004] It is also known that a protective tube for accommodating a temperature-responsive element can protrude through a container flange into the liquid heat store. Here, however, the temperature-responsive element must be easily removabl...
