concerning:

'' Electric storage heater with one made of individual core stones existing memory core "

The innovation relates to an electric storage heater with a single core stone Storage core, with the core stones built into the casing with built-in, horizontally laid and van wired Heating elements should be able to be used in front of the front.

With the previously known electric storage heaters, which were to be equipped with core stones from the front, the core had to be composed of differently shaped core stones many individual ü-channels developed. Another possibility was to use the heating elements during or after the installation of the storage core and to be wired, which, however, entailed the risk that the insertion and the wiring were not electrically correct took place.

The innovation has set itself the task of avoiding the above-mentioned disadvantages with regard to the use of differently shaped core stones and improper wiring and is based on the idea, despite heating elements previously built into the casing of the storage device - which is already expediently done by the manufacturer - cores of the same shape to be able to use an assembly of the device from the front, with only one air duct in the form of an inverted ¹¹ U ", which extends over the entire width of the core.

To solve this problem, it is proposed, according to the innovation, the cuboid core stones on their side surfaces at the level of the heating elements uniformly with horizontal running, the shape of the installed heating elements adapted, groove-shaped recesses to be provided when inserting the cores form receiving channels for the heating elements and the core stones at least on one side surface additionally with spacer cams to equip, whereby air channels or gaps are created between two adjacent stones. The air channels or gaps formed by pairs of adjacent core stones are expediently through a Shell-shaped baffle arranged above them connected to each other in terms of flow, oil * attached baffle, which the Air ducts for the rising air and the flowing air Air connects, contributes decisively to the fact that the core structure with such similarly shaped core stones from the front can be done. Likewise, because the heating elements are practically in the middle of the stones, direct radiation is generated this avoided on the baffle and on the other hand on the substructure. The bowl-shaped baffle are preferred Large radii are given in order to ensure that the air is deflected with as little resistance as possible and with as little noise as possible.

The baffle also replaces a specially shaped cap stone, as it is in the well-known storage heaters he + mmimmam & * m * ikaiBm0jmMme ** ei4mmm * mtmmiMfmtmk. which was usually very difficult to install.

The drawing shows the innovation in its details:

Show it:

Fig. ^ An overall view of the storage heater according to the innovation;

2 shows a single storage stone in side view; Fig. 3 in »front view

The storage heater according to FIG. 1 has two layers core stones arranged one above the other, each layer being formed by stones 1 of the same shape. The heating elements are prior to inserting the storage core into the casing installed and wired.

To solve the innovation task of being able to equip the storage heater with the core stones from the front with built-in heating elements and to be able to use cores of the same shape for this purpose, these have horizontally running, channel-shaped recesses 3, 3 ^{1 on their side surfaces at the level of the built-in heating elements 2, 2 1} , from which, when the stones are inserted, the recesses 3 in pairs form the receiving channels for the heating elements 2 and the recesses 3 ^{1 in} pairs form the receiving channels for the heating elements 2 ¹ .

The shape of the recesses depends on whether the heating elements are arranged horizontally (2) or vertically (2 ¹ ).

In a preferred embodiment of the innovation, one side face of each stone 1 has spacer cams at the corners 4, whereby the stones in pairs form air channels or gaps 5, 5 *, with the fresh air at A through the channel 5 rises and the heating air flows down through the channel 5 'to the air outlet B.

The two air ducts 5, 5 ¹ are connected to one another at the top by a shell-shaped guide plate 6, through which the air rising in duct 5 is diverted ^{into duct 5 1.} The shell-shaped baffle eliminates the need for a specially designed stone with a deflection channel.

In the case of loading from the front, the individual stones 1 are placed under or in a flat position, starting from the bottom advanced above the heating elements and then angled up into their vertical position. This process is repeated stone by stone and layer by layer.

The usual electrical connections for the heating elements 2, 2 are indicated at 7 and 8.

The shown arrangement of the heating elements in the middle area of the core stones has the heating in relation to the Advantage that the middle part of the storage core by direct heat conduction of the heating elements to the adjacent stones is heated much more than the outer part of the storage core.

A temperature equalization between the. inner and outer core part can only be achieved by radiation and direct ^ · heat conduction take place via the spacer cams 4 of the core stones. This makes the outer surface of the core essential has a lower temperature than the rest of the core, and that correspondingly thinner insulation is required, whereby a flatter design is made possible.

The special shape of the memory core makes it possible, in principle, to manufacture a series of devices that can be found in the Differ in height. If the storage heater is built with two layers on top of each other, it fits under window sills with normal ones Height. If, on the other hand, only one core stone layer is used / ends, then Place the storage heater under low window sills. Both series have an even phase load the three-phase network through the proposed arrangement of the Heating elements guaranteed.
