Abstract
Die Vorrichtung beschreibt ein System, mit dem die an einem Cardiogerät durch den Benutzer aufgebrachte Energie in elektrische Energie umgewandelt und sehr effizient in ein Stromnetz eingespeist werden kann, wobei der Benutzer die Trainingsintensität an der Vorrichtung einstellen kann. Dazu wird durch die Bewegung des Benutzers ein elektrischer Generator angetrieben. Der durch diesen erzeugte elektrische Strom wird mithilfe einer steuerbaren Leistungselektronik in ein Stromnetz (z. B. Hausnetz) eingespeist. Über eine mit der Leistungselektronik verbundene Steuereinheit kann der Benutzer das Bremsmoment bzw. die an das Stromnetz abgegeben Leistung auf verschiedene Stufen einstellen. Diese Vorrichtung wird in erster Linie in Cardiogeräten für Trainings- oder medizinische Zwecke eingesetzt.The device describes a system with which the energy applied to a cardio device by the user can be converted into electrical energy and very efficiently fed into a power grid, whereby the user can adjust the exercise intensity on the device. For this purpose, an electric generator is driven by the movement of the user. The electrical power generated by this is fed into a power grid (eg house network) using controllable power electronics. About a connected to the power electronics control unit, the user can set the braking torque or the output power to the power supply to different levels. This device is primarily used in cardio machines for training or medical purposes.
Description
Die Erfindung betrifft eine Vorrichtung bzw. eine Anordnung mehrerer solcher Vorrichtungen zur Erzeugung einer Trainingslast bei Cardiogeräten, mit der elektrischer Strom erzeugt und so aufbereitet wird, dass dieser in ein Stromnetz eingespeist werden kann.The invention relates to a device or an arrangement of several such devices for generating a training load in cardio equipment, is generated with the electric power and processed so that it can be fed into a power grid.
Bereits bekannt sind Cardiogeräte, bei denen die vom Trainierenden aufgewendete Muskelarbeit in einem mechanischen oder elektromagnetischen Bremssystem dissipiert wird. Ebenfalls bekannt sind Cardiogeräte, die einen Teil der aufgewendeten Energie in elektrischen Strom umwandeln, der für die Deckung des Strombedarfs des Geräts genutzt wird.Cardio machines are already known in which the muscle work expended by the exerciser is dissipated in a mechanical or electromagnetic brake system. Also known are cardio machines that convert some of the energy used into electrical power used to meet the device's power requirements.
Cardiogeräte jedoch, die den größten Teil der Muskelarbeit möglichst effizient in elektrischen Strom umwandeln, der in das Hausstromnetz oder das öffentliche Stromnetz des Energieversorgungsunternehmens eingespeist werden kann, sind bisher am Markt nicht verfügbar.However, cardiovascular equipment that converts most of the muscle work into electricity as efficiently as possible that can be fed into the utility company's utility grid or public utility grid is not yet available on the market.
Aus der Patentliteratur ist eine entsprechende Vorrichtung bereits bekannt (
Zum anderen wird bei der Kopplung mehrerer Cardiogeräte jeweils für jedes Gerät ein Spannungsregler zwischengeschaltet, was die Gesamtkosten des Systems erhöht.On the other hand, when connecting multiple cardio devices, a voltage regulator is interposed for each device, which increases the total cost of the system.
Nach dem Stand der Technik allgemein bekannt ist zudem die Möglichkeit, mittels windbetriebener Propeller oder Photovoltaikelementen Energie zu erzeugen und in ein Stromnetz einzuspeisen. Die Bereitstellung dieser Technologie ist jedoch aufwändig und teuer.In addition, according to the state of the art, it is generally possible to generate energy by means of wind-driven propellers or photovoltaic elements and to feed it into a power grid. However, the provision of this technology is cumbersome and expensive.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung der eingangs beschriebenen Art zu schaffen, die die genannten Nachteile vermeidet und so die Möglichkeit der kosteneffizienten Stromerzeugung mit der Funktionalität herkömmlicher Cardiogeräte verbindet.The invention has for its object to provide a device of the type described above, which avoids the disadvantages mentioned and thus combines the possibility of cost-effective power generation with the functionality of conventional cardio equipment.
Nach der Erfindung besitzt die Vorrichtung einen Generator, der über einen Permanentmagneten oder einen externen Erregerstrom ein Magnetfeld erzeugt. Dieser Generator wirkt als Bremssystem, das in Abhängigkeit von der im Cardiogerät aufgewendeten Muskelarbeit elektrische Energie erzeugt. Weiterer Systembestandteil ist ein Gleichrichter, der den Wechselstrom des Generators in Gleichstrom umwandelt. Dieser Gleichrichter ist mit einem Wechselrichter verbunden, der den Gleichstrom in Wechselstrom umwandelt, welcher bezüglich Phasenlage, Frequenz und Spannung so angepasst ist, dass er in ein vorhandenes Stromnetz (Haus- oder öffentliches Stromnetz) eingespeist werden kann.According to the invention, the device has a generator which generates a magnetic field via a permanent magnet or an external exciting current. This generator acts as a braking system that generates electrical energy depending on the muscle work done in the cardio machine. Another system component is a rectifier, which converts the AC of the generator into DC. This rectifier is connected to an inverter that converts the direct current into alternating current, which is adjusted in terms of phase, frequency and voltage so that it can be fed into an existing power grid (domestic or public grid).
An diesen Zwischenkreis können mehrere Gleichrichter parallel oder seriell angeschlossen werden, an denen wiederum jeweils eingangsseitig ein Generator angeschlossen ist. Auf diese Weise können mehrere Cardiogeräte an einen Wechselrichter angeschlossen werden.Several rectifiers can be connected in parallel or in series to this intermediate circuit, to each of which in turn a generator is connected on the input side. In this way, several cardio devices can be connected to an inverter.
Anders als in der oben genannten Offenlegungsschrift (
Der beschriebene Aufbau ermöglicht die Einsparung des nach der vorgenannten Offenlegungsschrift für jedes einzelne Gerät erforderlichen Spannungsreglers.The structure described makes it possible to save the voltage regulator required for each individual device according to the aforementioned disclosure.
So eignet sich die Erfindung zur effektiven Senkung der Stromkosten insbesondere in Einrichtungen, die den Trainierenden mehrere Cardiogeräte zur Verfügung stellen, wie z. B. Fitnessstudios.Thus, the invention is for effective reduction of electricity costs, especially in facilities that provide the trainees several cardio machines available, such. B. gyms.
Der Vorteil der Erfindung besteht zunächst darin, dass die auf diese Weise erzeugte Energie nicht verloren geht, sondern in Form elektrischer Energie nutzbar gemacht wird. Hierdurch kann der Anwender des Systems seine vom Energieversorgungsunternehmen bezogene Energie und somit die Kosten dafür reduzieren. Es handelt sich dabei um eine emissionsfreie, erneuerbare Energiequelle.The advantage of the invention consists firstly in the fact that the energy generated in this way is not lost, but is made usable in the form of electrical energy. As a result, the user of the system can reduce its energy purchased by the utility company and thus the cost thereof. It is an emission-free, renewable energy source.
Ein weiterer Vorteil besteht in der kostengünstigen Erzeugung elektrischer Energie durch die Erfindung, da durch den beschriebenen Aufbau, anders als in der vorgenannten Offenlegungsschrift, keine zusätzlichen Spannungsregler eingesetzt werden müssen, was die Systemkosten senkt und den Wirkungsgrad erhöht.Another advantage is the cost-effective generation of electrical energy by the invention, since no additional voltage regulator must be used by the described structure, unlike in the aforementioned Offenlegungsschrift, which reduces the system cost and increases the efficiency.
Ein anderer Vorteil besteht in der Möglichkeit der elektronischen Verstellbarkeit der Trainingslast über die Erregerspannung des Generators oder den Gleichrichter, weshalb ein vorgeschaltetes mechanisches mehrstufiges Getriebe nicht erforderlich ist. Dadurch reduzieren sich sowohl Bauraum und Gewicht als auch der Wartungsaufwand der Erfindung deutlich. Des Weiteren erlaubt dieses System eine stufenlose Verstellung der Trainingslast in einem breiten Bereich, was zu den Grundfunktionen eines modernen Cardiogerätes gehört.Another advantage is the possibility of electronic adjustment of the training load on the excitation voltage of the generator or the rectifier, which is why an upstream mechanical multi-stage transmission is not required. This reduces both space and Weight as well as the maintenance of the invention clearly. Furthermore, this system allows a continuous adjustment of the training load in a wide range, which is one of the basic functions of a modern cardio machine.
