Heat accumulator apparatus with a housing

摘要

In the case of a heat accumulator apparatus, the front wall 7 and the top wall 3 can be detached from the cuboid housing. Heat-insulating plates 2 are situated between these walls and an accumulator core 1. In order to obtain a stable housing structure and an additional support for the front-side heater-insulating plate 2, the edge strip 4, running parallel to the front wall 7, of the top wall 3 is offset in a z-shape downwards and forwards as a step 5. The free end leg 6 of the edge strip 4 in this case runs in the area parallel to the front wall 7 and engages between the front wall 7 and the neighbouring heat-insulating plate 2. In addition, the front wall 7 has a bent edge 8, 9 which fills the step 4, 5. <IMAGE>
