Electric storage heater with a storage core traversed by vertical air supply and air discharge edges, a cold air supply duct arranged below the air supply ducts, acted upon by a fan, from which cold air can flow into the air supply ducts underneath one or more air supply ducts the air discharge channels arranged Liift ~ IAEE!

Cold air opened and with decreasing heating through the one from the storage core escaping air is closed more and more.

In known storage heaters of this type (DE-Gbm 84 18 551.1, DE-Gbm 73 07 758, DE-Gbm 18 97 113, PS 2 040 564, PA 253 515, ÖP 266 271 or AT-PS- 279 750) acts on the in the unit base permanently installed Air flow entering the air mixing chamber from the storage core the bimetallic element, which then opens the air mixing flaps so far that the temperature of the air heated from the storage core and mixed in Cold air formed air mixture has a constant outlet temperature. The particular advantage of this type of outlet temperature control is there in the fact that the regulation takes place with purely mechanical means and is therefore extremely robust and operationally reliable.

The disadvantage of the known storage heaters is that all of the promotion, Mixing and guiding the air required components components of the base or are welded or screwed to this. To this assembly In addition, cold air supply and air mixing chambers can be installed in different vertical planes and the air intake chamber is usually arranged on the side of the device. As a result, these devices have correspondingly large External dimensions.

The aim of the invention is to provide an electric storage heater To create the type mentioned at the beginning, in which a separate assembly contains all the functions necessary for the air volume. In addition, should the demand for more compact devices will be taken into account.

To solve this problem, the invention provides that a replaceable at any time Insert, the so-called air chamber, is structurally designed so that all of them are required for conveying, mixing and guiding the air Has functional features and the associated components such. B. blower and bimetallic element as well as possibly also the electrical direct heating, contains. In order to reduce the external dimensions of the device, air intake, cold air supply and air mixing chamber housed in a vertical plane below the storage core base.

The idea of the invention is therefore to be seen in the fact that the flat, Drawer-like air chamber, detached from the device base, as a separate assembly can be prefabricated. This has significant manufacturing advantages, because the final assembly of the electric storage heater through

the onset of the! Vorgafer only redeemed · ^ uftVammeτ on the electric view Connection refers. In addition, maintenance (e.g. cleaning the fan rollers, of the air distribution housing etc. from dust? one in operation located device as well as any necessary service work (exchange of the blower), since the air chamber can simply be pulled out after loosening the air outlet grille. After removing the electrical leads you can use the air chamber z. B. for cleaning as well Place the repair in a convenient working position on the table or replace it.

A preferred embodiment is characterized in that one parallel the side of the air chamber running towards the front of the device is designed as an air outlet grille.

It when designed as an air outlet grille is particularly advantageous Side detachably fastened directly to the electric storage heater as an individual part « 1st. The air chamber housing is then particularly simple, as it consists of the bottom and the 2 narrow sides and one broad side or the lower rear wall tinem sheet metal cutting is cheap to manufacture.

In a preferred structural embodiment it is provided that in the The cold air supply chamber is integrated on the back wall, the underside of which is prepared to accommodate the fan.

A structurally and effectively particularly preferred embodiment is like this designed that the features mentioned in DE-Gmb 84 18 151 are taken into account with regard to a particularly favorable air balance. Here is one separating the cold air supply chamber and the air mixing chamber, a double function exerting flap available, which steadily from a closed position over an open position is adjustable up to a blocking position. This flap opens the direct connection from the cold air supply chamber to the mixing chamber in the same ratio as it closes the transverse slot in order to split the cold air flow into the corresponding cold air partial flows. One in the mixing chamber arranged bimetallic element actuates the flap via a connection in the sense that the flap is opened when the temperature is high and when it is decreasing Heating is closed more and more. To avoid emptying the storage tank in the case of direct heating, it is provided that the flap In is over the open position beyond the locked position is pivotable in which they the The flow path to the air supply channels is closed, but at the same time the direct connection from the cold air inflow chamber to the mixing chamber is correspondingly closed opens. Direct heating elements are arranged in the mixing chamber in such a way that when the Direct heating because the bimetal element moves the flap into the blocked position .

The invention is described in the following, for example, with reference to the drawing; in this shows:

Flg. 1 shows a cross section through the lower part of a device according to the invention Electric storage heater

Fig. 2 shows a three-dimensional representation of the air chamber (10) from behind Flg. 3 shows a three-dimensional representation of the air chamber (10) from the front

According to the drawing, there is a housing (35) in the lower pond an invented electric storage heater one, from the broadside the device is accessible from the opening with an air outlet grille (28) is screwed. Behind this air outlet grille, below the storage core (33), there is the cavity (29) for receiving the air chamber (10).

The drawer-like air chamber (10) faces the front of the device (34) open, while the opposite rear side (16) consists of an upper part (17) and a lower part (18) arranged offset thereto. Of the The area in between can be pivoted about an axis (25) which is parallel to the front of the device and is controlled by the bimetal element (23) stored air mix flap (24) more or less closed.

The upper part (17) and lower part (18) of the rear side (16) are offset to the extent that that there is sufficient width for the cold air supply chamber (12) or that their width corresponds approximately to that of the air supply channel (31). From the through the device rear wall (30) and air chamber rear wall (16) formed cold air intake chamber (11) the air conveyed by the fan (26) enters the cold air supply chamber (12), where, depending on the position of the mixing flap (24), more or less air for discharging the storage core or for mixing with the air from the air exhaust ** guide channels (32) branched off into the air mixing chamber (13) flowing air will. While the cold air supply chamber (12) goes up to the air supply channel (31) in the memory core (33) is open, is located below in an appropriate Inclined position a base (20) which has openings (21) in the area of the fan (26).

The air chamber (10) can after removing the air outlet grille (28) from the Cavity (29) below the storage core (33) in the dash-dotted line in FIG position shown are pushed. After removing the electrical connection (36), the air chamber (10) is completely free from the device (35).
