Definitions

  • the present invention relates to a multifunctional device according to the preamble of claim 1.
  • Devices of this type which are supplied with energy in a self-sufficient manner, are preferably used for location-independent facilities, such as, for example, sales stands or trolleys, whether on beaches, in shopping streets, in hiking areas, or the like.
  • DE-GM 84 18 489 describes, for example, a hand-pushed ice cream truck that has a generator driven by a gasoline engine with a charging device for supplying the cooling unit. It proves disadvantageous that - although the cooling unit and possibly other consumers, such as a water heating device, can be supplied with the required current after charging the accumulator or the battery - the charging process, which has to be carried out again and again, is caused by the running gasoline engine noise and generates exhaust gases, which is neither sympathetic and beneficial for the sale, storage and transportation of ice cream, nor for use at locations chosen for their recreational and leisure character, can be regarded as advantageous .

It is obvious that such a cool box can only be used to a limited extent, both in terms of the cooling time, the goods to be cooled and in purely self-sufficient operation.
  • the invention has set itself the task of providing a cooling device that can be operated independently of location for long periods of time, in particular other consumers can also be operated optionally, and wherein the energy supply is a so-called alternative energy supply without there is a need for the use of conventional auxiliary energy systems.

  • Actuators advantageously serve to limit the charging current supplied to the electrical energy store, corresponding to the maximum permissible value of the charging current.
  • the control of the speed of the rotor blades can also take place by means of the actuators, these being adjustable if necessary. At high wind speeds, the wind rotor can be switched off via these actuators, or a variable equivalent load can be connected to the wind generator to prevent overvoltage when the electrical store is charged. Simplified, this is made possible by the use of a control device which supplies the respective values for the voltage at the electrical energy store and for the current strength of the electrical energy supplied to the latter and which uses these to control the actuators.
  • a priority generator Via a priority generator, it is possible to give the control device a signal to select a specific energy system, which is of particular interest if one of the energy systems is only available for a short time or only at this time.

It then becomes possible to control the supply of the cooling air via the signal of the sensor provided in one of these further cooling rooms, which can be done by actuating a valve which may be designed as a flap.

So that this alignment is possible, unaffected by glare radiation, such as reflective window panes, glistening water surfaces and snow, or light rock surfaces, at least glare protection covers should be provided for the solar direction sensors.
