A technical possibility of executing the invention is on hand of the schematically illustrated drawings

Fig. 1 heat storage heating, function diagrams,

Fig. 2 heat storage floor mat (cross section),

Fig. 3 control unit with integrated micro-computer,
given and should be explained in detail as follows:
In Fig. 1 you can see the 220 volt alternating current generator 1 , the 220 volt AC circuit 2 , in the current flow direction main fuse 3 , main switch 4 , from there to a fuse relay field and associated field of view diode indicator 6 for the optical control of the function.

From here, the current is passed to an AC distributor 7 .

A rectifier 14 is controlled separately from the generator. By means of a plug connection, an AC connection line 8 is guided from the AC distribution connection socket 7 to a heat storage mat.

The DC circuit 15 is important for the operation of the heat storage floor mats.

It consists mainly in the control of the driving tool battery 16 , further to a fuse box 17 , a control unit 18 with an integrated microcomputer and finally the connection of a direct current distribution socket and control cable connection 19 .

About connector DC, such as control line 20 , the existing in the heat storage doormat 9 rotary rollers blower 23 and the ventilation flap 26 and the inner flap 40 is controlled.

About a membrane air intake 29 with outlet connection clip 30 , a connecting duct 31 , the Wärespei cher doormat 9 is connected.

In the same way as described and as can be seen in FIG. 1, the heat storage floor mats 10 and 11 are functionally integrated in the heat storage heater.

For the actuation of the inner flap 41 , however, only the heat storage floor mat pair 9 and 10 can be considered. The heat storage doormat 11 is then to be used separately when starting the vehicle to support the vehicle's own heating until the engine warms up.

Fig. 2 shows the structure and principle of operation of a heat storage doormat as a retrofit / element.

The heat storage doormat 9 has a ventilation flap 26 with time-controlled activation of the control device 18 .

There is also an air outlet opening 44 and a rotary roller blower 23 which also responds to the same control impulse. The same applies to the floor mats 10 and 11 .

Here it is the air outlet openings 45 and 46 , as well as the rotary roller blowers 24 and 25 .

The heat storage floor mats 9 and 10 arranged in a modular manner to each other, each have an inner flap 40 and 41 with air outlet openings such as connecting pieces 42 and 43 , which are controlled depending on the temperature via temperature sensor 58 and control unit 18 .

The heat storage floor mat 9 as ( 10 and 11 ) has a heat storage core plate 48 and a package of heat storage lamella lenplatten 49 with intermediate heating spirals 56 , such as a circulating air duct 57 around the lamella package. Around the circulating air duct is a mosaic platelet body and a circumferential thermal insulation plating 51 . On the top as a footrest, the doormat is equipped with adapted textile cover 52 .

The power supply to the heating spirals takes place via a power connection rail with an input connector 55 .

The operation of the heat storage heater described is determined by 3 usage situations.

In detail:
Situation 1 = traffic jam situation
Situation 2 = time situation
Situation 3 = temperature situation.

The basic requirement is that for optimal operation ability to produce sufficient heat capacity. That depends solely on the running time of the motor vehicle from.

As a result of the vehicle running, the generator produces one 220 volt AC voltage.

The current becomes zen via fuse elements, main switches tral arranged socket headed.

Continue via cable connection to the heating coils of the heat storage cher floor mats.

The heat produced is stored in the core storage plate like that Slat plates saved.

The flexible ceramic tile body compensates the stored heat balance.

The all-round thermal insulation panel insulates the heat package.

The generator is powered by an AC rectifier Direct current via the vehicle's own battery to the control unit headed with integrated microcomputer.

From here a direct current, control line goes to the plug bushings; via further pluggable cabling to the ventilation fold and rotary roller blowers into the heat storage foot Mats.

When a respective control impulse is triggered, the Rota  tion roller blowers to rotate, the ventilation flaps opened synchronously.

This means that vehicle interior air is applied above the central one Membrane intake in the recirculation channels of heat vacuumed floor mats.

Through the gaps between the heat storage core plates to the Lamellar plates, the air ducts to the ceramic Sheathing bodies, the air in the heat storage foot mat ten mixed, heated via the rotary rotary fans and opened ventilation flaps back into the vehicle interior transported.

The air flow is fully blackened by arrows Tip marked.

By opening the inner flaps and synchronously to the control pulse to the rotary roller blowers, the heated mix can air over the connecting piece of the existing heating system as transported another variant into the vehicle interior become.

The vehicle interior temperature rises and becomes:

• - Automatic / temperature setting to the desired room temperature
• - Automatic / time setting until the desired off time,

brought. When the respective control pulse is triggered, the Rotation roller blower switched off and synchronized with the Inside, or the ventilation flaps closed. The heating process is now complete.

The load level of the heat storage plates for visual inspection can be driven using a dedicated set of instruments device.

The design of the storage capacity of the heat storage foot mat ten or the 1 element / heat storage fixed block depends essentially on the vehicle type intended for this.

The cubic meter of space to be heated plays a decisive role hold of the respective passenger compartment as a design parameter the crucial role.

The aim should be a technical implementation that is through simple operation, solid basic design and good Price, performance ratio, offers.

These requirements should be the retrofit kit, like the factory basic equipment apply equally.
