Author of the invention MIKULÁŠ FRANTIŠEK, NITRA (54) Heating liner for combined domestic water heating 1

BACKGROUND OF THE INVENTION The present invention relates to a heating element for combined heating of domestic water in containers.

So far, the combined utility water heating is provided by the yard by self-independent methods. It is electrically, by direct heating of domestic hot water by an electric heating element, or by a heating element of a different construction, operating equally. In the first method of heating, directly by the electric heating body, as a result of its high surface temperature, minerals are released from the water, which in the form of hard incrustations settle the surface of its heat exchanging surfaces, thereby gradually decreasing performance until the body is destroyed as a result of overheating. In the heating mode, the heating medium flows from the heat source to the top of the heating element and passes heat to the heated water in the reservoir through the heat transfer surfaces. The cooled returns to the bottom of the heat source to sleep. Because of this principle, it is not possible to place the heating elements of such a design in such a way that the hottest part of the heating element passes through the lowest, i.e. even the most heated layer of heated water in the reservoir, which is particularly important for low potential media. 2

The aforementioned drawbacks are eliminated by the design of the heating element, the principle of which is the heating of the service water by two circulating rings with a lower inlet of the common carrier medium. The medium, while transferring heat, rises through the center rim of the liner, where the electric heater body is incorporated, to the upper portion of the bolt tube and circulates through the inner circuit to sleep into the lower expanded tube body.

The main advantages of the design of the heating element according to the invention are that the heat transfer medium comes to the heating element in the lower part, as a result of which the container can advantageously be placed at the lowest point, that is to say in the hottest layer of heated water. perfect heat transfer from the heat transfer medium is guaranteed. The merging of two separate heats via a common heat transfer medium ensures the safety of the installed thermal power of the electric heating element and prevents the minerals in the form of an encrustation of its surface and thus its deterioration due to overheating.

According to the invention, an exemplary embodiment of the heater 227259 is shown in the drawing
