Definitions

  • the invention relates to an auxiliary device for an electrical device, with a display device for displaying a state of the auxiliary device, wherein the display device comprises a display element for supplying electrical energy to be displayed element.
  • the electrical device can in principle be any electrical consumer.
  • An object of the present invention is therefore to provide a particularly reliable status display for such an auxiliary device.
  • auxiliary device having the features specified in claim 1. Thereafter, it is contemplated that a display element is used, which maintains a display state in the absence of power supply.
  • a central idea of the invention is to use, instead of the purely mechanical display devices exclusively used in the prior art, a display device with a display element which is independent of a supply the display device with energy maintains the display. With the use of such a display element, a particularly reliable status display is possible. Due to the elimination of moving parts and mechanical connections, the risk of malfunction and failure is significantly reduced. Intermediate positions of the ad, which do not allow a clear indication of the state, are excluded from the outset.
  • the display element In order for the display element to maintain the display with energy independent of supply of the display device, the use of special materials is preferably provided, in particular those materials which can maintain a display state independently of energy over a relatively long period of time. Accordingly, the display device is preferably at least partially made of a material which does not require energy for display.
  • the display element comprises a cholesteric liquid crystal display.
  • a cholesteric liquid crystal display In contrast to a traditional liquid crystal display, energy is only needed for cholesteric liquid crystal displays when writing information, but not when displaying it.
  • a liquid crystal display is characterized by comparatively wide viewing angles and high contrast.
  • Basic information on the technology of cholesteric liquid crystal displays are inter alia in the patent DE60308108T2 contain.
  • the display element consists at least partially of an electrophoretic material.
  • the principle in this case is that black and white, positively and negatively charged particles suspended in a liquid or gel are moved through this medium when an electric field is applied thereto. This can be done the surface a monochrome grayscale image are generated.
  • Basic information on the technology of electrophoretic displays are inter alia in the patent DE60107396T2 contain.
  • the display element consists at least partially of an electrochromic material.
  • An electrochromic material is understood to be a material which is capable of permanently changing its optical properties, in particular its color, when a voltage is applied for a short time.
  • electrochromic materials are, for example, tungsten oxide (WO 3 ) and other metal oxides in question, such as. Nb 2 O 5 , TiO 2 , NiO, MoO 3 , Ir 2 O 3 , V 2 O 5 .
  • the color change is reversible and occurs by momentary reversal of the voltage.
  • Basic information on the technology of electrochromic displays are inter alia in the patent DE602004001508T2 contain.
  • the display element has an electrochromic or electrophoretic coating, in other words the electrochromic or electrophoretic material is used as a layer.
  • the electrochromic or electrophoretic coating can take place by printing on a housing surface of the auxiliary device with electrochromic or electrophoretic ink.
  • the preferably made of plastic housing of the auxiliary device serves as a carrier for the coating.
  • the terminals for applying the display switching voltage for the color change can be realized as printed circuit traces, for example, so that the entire manufacturing process of the display element can be carried out with lithographic production techniques, as have long been tested. As a result, the manufacturing costs of the display device, in particular compared to conventional mechanical display devices, can be significantly reduced.
  • the states of the auxiliary device can be much more flexible compared to conventional mechanical display devices, which often have only two or three fixed mechanical display elements.
  • the representation of fixed letters, numbers and / or symbols by the use of a mask covering the display surface is possible.
  • a plurality of individually controllable display elements can be used in the display device, whereby different states of the auxiliary device can be displayed.
  • the arrangement of these plurality of display elements may be e.g. segmental, so that a kind of bar display is created.
  • any other forms of display and structures are conceivable.
  • the display device comprises a plurality of display elements, states of a plurality of state parameters can also be mapped.
  • auxiliary devices that do not have their own power supply, as for a color change of the display element only a brief application of a (comparatively low) voltage is required.
  • electro-optical display elements such as light-emitting diodes (LED) or conventional liquid crystal displays (LCD) once assumed display state remains permanently unchanged until the color change is canceled by a corresponding "counter-voltage".
  • the invention is therefore particularly suitable for auxiliary devices that provide power elsewhere, in particular via the power supply of the electrical device.
  • auxiliary device is supplied via the power supply of the electrical device
  • the auxiliary device is supplied via the power supply of the electrical device
  • the invention is very particularly advantageous in the case of overload relays for the protection of electrical devices, such as, for example, electric motors.
  • the indicator of the overload relay then serves primarily to the switching position display of the output relay contacts.
  • Other application examples of the invention are securing devices for the household or the like.
  • FIG. 1 there are shown a number of auxiliary devices for an electric motor (not shown).
  • the auxiliary devices are monitoring and / or control devices, such as a motor starter and an overload relay 1.
  • the overload relay 1 is characterized in that it does not have its own power supply. The power supply of the overload relay 1 instead takes place via the power supply of the electric motor via a fundamentally already known electromagnetic coupling.
  • the overload relay in addition to controls 2 and a display device 3.
  • the display device 3 is used to display a state of the overload relay 1, in particular for switching position display of the output relay contacts.
  • the display device 3 comprises a display element 11, which essentially consists of an electrochromic material based on WO 3 .
  • the display element 11 is, as in FIG. 2 shown as a coating of a plastic carrier 4, here the device housing executed.
  • the plastic carrier 4 is printed with electrochromic ink.
  • the terminals 5 for applying the display switching voltage for the color change are realized as printed circuit traces.
  • FIG. 3 An embodiment of a display element in the state "not triggered” is in FIG. 3 shown.
  • the display element 12 is briefly supplied with a voltage pulse which is suitable for permanently changing the color of the display element 12.
  • the display element 12 maintains its display state.
  • the display element 12 off FIG. 3 is then discolored and thus indicates the state "triggered", cf. FIG. 4 ,
  • the switch position display can be formed by letters.
  • the display device 3 comprises two display elements 13, 14 ("not triggered” and "triggered"), cf. FIGS. 5 and 6 ,
  • the segment display shown there comprises a plurality of adjacently arranged display elements 15, 16, 17, 18, 19 and serves, for example, to represent the heating of the electric motor.
  • five display elements are provided, their activation in each case to reach a predetermined percentage of a threshold value equivalent.
  • the two first display elements 15, 16 are active.
  • a direct electrical connection to the power supply of the electrical device is present in the simplest case. While the electric motor is running, the overload relay 1 is constantly energized, which is buffered in a memory (not shown). In the case of triggering the overload relay 1, a switching voltage pulse for the color change of the display element is generated from the stored energy. The return to the initial state (renewed color change) is preferably carried out manually by applying a correspondingly reversed voltage.
  • the display device 3 preferably comprises a correspondingly designed control element (not shown) next to the display element, which corresponds to the present states of the overload relay 1 to the individual display elements 11 -19 at the appropriate times applies the appropriate indicator switch voltages.
