Definitions
- the present invention relates to an electric Walkervor ⁇ device for dispensing a heated air stream, in particular for heating of a sanitary room in a rail vehicle.
- the first securing stage is generally realized by a reversible temperature switch which, after reaching a specified excess temperature via a relay, interrupts the power supply to a heating element within the heating device. After cooling of the reversible overtemperature switch, which is usually carried out via a thermistor or a bimetal, the heating element is reactivated.
- the object of the invention is to provide an electrical Schuvorrich ⁇ tion, which has a high reliability, and in particular allows a safer separation of the heating element from the power supply.
- the object is achieved by the features of the inde- pendent claims ⁇ . Advantageous embodiments are specified in the subclaims.
- an electric heater for the purpose of ⁇ off a heated air flow, in particular for heating a sanitary room in a rail vehicle, with an air duct and a fan for generating the air flow, a heating element for heating the air flow and a first overtemperature switch, wherein the fan and the heating element are arranged in the air passage, and wherein the first over-temperature switch is designed to switch off the heating element reversible in overwriting ⁇ processing a first high temperature, further comprising, to disable a second over-temperature switch which is performed when exceeding a second over-temperature, the heating element irreversible, and wherein a trough is formed on the air duct, the second overtemperature switch is arranged in the trough, and the second overtemperature switch has a thermally actuable disconnecting switch for switching off the heating element, wherein the thermally triggered disconnect switch can be triggered by a glass bead bursting when the second overtemperature is exceeded.
- a connection or disconnection of a heating element is often carried out via a contactor or a relay.
- a first advantage of the heating device according to the invention is that an interruption of the power supply of the heating element does not take place via a relay controlled by a second overtemperature switch, but via the second overtemperature switch itself. This means that a known from the prior art relay is eliminated. The second overcurrent switch is thus integral. This integration provides further benefits.
- the air duct of the heating device according to the invention has a trough in which the second overtemperature switch is arranged.
- the trough with the second transfer Tempera ⁇ turschalter is advantageously designed such that the is Studentstem ⁇ peraturschalter substantially adjacent the air stream angeord- net.
- the second over-temperature switch is arranged in a depression of the air duct such that the air flow can flow substantially unhindered past it from the second over-temperature switch.
- the second over-temperature switch is advantageously so arranged in ner egg tray of the air passage that the formed by the two ⁇ th over-temperature switch flow resistance is negligible. This feature offers the advantage that almost no turbulence of the air flow takes place through the second overtemperature switch. This allows for the same fan power a comparatively high air flow and low due to the air flow operating noise.
- the triggering of the second overtemperature switch by a bursting glass ball as an actuator offers the advantage that due to the brittle property of glass is not gradual, but an abrupt change in shape of the actuator. A gradually rising temperature leads to an irreversible and abrupt change in shape of the glass sphere when the second excess temperature is exceeded, so that the disconnect switch can be triggered abruptly. The risk of sticky contacts or the formation of arcs can be reduced in this way.
- the electric heater is advantageous in such forms ⁇ out that the isolating switch comprises a switching mechanism including a biassed by a spring switching element and a switch, wherein the switching mechanism carried is to open the switch on the switching element irreversible when it tripped.
- An electrical heating device in which a biased by a spring switching mechanism can trigger an opening of a switch, offers the advantage that when a triggering of the overtemperature switch stored in the biased ⁇ spring energy for the application of a force is available with which a Separation of the contacts of the switch can be performed or supported. It thus offers an advantage, in particular in applications in which, due to increased corrosion conditions, but also due to aging processes or contact firing, "sticking" or "caking" of live contacts can occur.
- the switch is preferably designed as an opener.
- the switching element is preferably designed as a bridge.
- Such a design has the advantage that it is structurally simple to implement. This can be done, for example, such that the switching element connects the switching contacts of a switch as a conductive bridge.
- the glass bead, preventing the force ⁇ biased by a spring switching element leaves the position in which the switch contacts of the switch are connected. When the glass ball bursts, the spring travel of the pretensioned spring is released so that the spring force causes the disconnector to open.
- the electric heater is advantageous in such a way out forms ⁇ that the glass bead contains a is expandable by heat expansion liquid, wherein the glass bead when crossing the second over-temperature can be destroyed, and wherein the biased by the spring switching element can be triggered by the destruction of the glass bead.
- This embodiment has the advantage that, in order to bias the switching mechanism, a large spring force in relation to the dimensions of the excess temperature switch can be absorbed by the undestroyed glass bead, which however is suddenly released in the event of destruction of the glass bead for opening switch contacts. This allows to ⁇ reliable operation of the switch.
- the electric heater is advantageous in such forms ⁇ out that the thermally triggerable circuit breaker is directly in a current path for supplying power to the heating element angeord ⁇ net.
- Such an arrangement offers a high degree of Be ⁇ reliability, since in a direct interruption of the current path in comparison to an indirect or indirect interruption no intermediate switching means are to be operated.
- the electric heating device is designed in such a way that the air channel has an opening for the purpose of forming a depression, which opening is covered by a hat-shaped heat protection.
- a hat-shaped heat protection allows to record the second overtemperature switch and to close the air duct against leakage of the air flow from the air duct.
- the electric heating device is designed such that the air channel is formed from sheet metal and / or the hat-shaped heat protection is formed by a cover plate.
- An executed example as a punch-bending element Ab ⁇ cover plate is heat resistant and at the same time easy and inexpensive to produce.
- the electric heater is advantageous in such forms ⁇ out, that the air flow having a predetermined flow direction through the fan in the air duct and the trough in Flow direction is arranged in front of the heating element. Triggering of the second overtemperature switch therefore essentially takes place on the basis of a radiation heat emitted by the heating element.
- a fault case for example, in case of failure of the fan or in a blockage of the air duct, especially at the inlet or outlet, due to there befindlichem luggage, dirt or debris occur.
- the sensor of the first over-temperature switch at the height of the heater, or behind the heating element is advantageously arranged at ⁇ . Such an arrangement entails that the first overtemperature switch is arranged in the immediate vicinity of the heating element, so that at the location of the sensor of the first overtemperature switch very much a higher
- Temperature is to measure than at the location of the second overtemperature switch. This would cause high, even at the same pre- ⁇ passed over temperatures for both over-temperature switch of the first reversible switching overtemperature switch in each case prior to the second irreversibly switching over temperature switch.
- the electric heater is advantageous in such forms ⁇ out that the sensor of the first over-temperature switch before and is arranged in relation to a provided example, in a rail vehicle ⁇ installation direction centered over the heating element.
- the highest temperature prevails at this point due to the heat convection, as a result of which a rapid starting of the first overtemperature switch can be achieved.
- the electric heating device is designed such that the air duct has an inlet and egg ⁇ nen outlet and a thermostat sensor for controlling the heating element is centrally angeord ⁇ net in the air flow in front of the outlet. Further advantageously, the thermostat sensor is closer to the outlet than arranged to the heating element.
- a Derar ⁇ term positioning the thermostat sensor leads to a comparable same low disturbance of the homogeneity of the air flow and at the same time allows a representative detection of the temperature of the air flow emitted by the heater.
- the thermostat sensor, and the sensor of the first over-temperature switch are advantageous advantageous in its cross ⁇ cut round, oval, drop-shaped or flat design, since only a small flow resistance is formed by them in such a configuration in the air duct.
- the electric heating device is advantageously designed such that the air duct has guide plates for guiding the air flow.
- the air duct is advantageously ⁇ timiert such op by baffles that its flow resistance is minimized.
- Deswei ⁇ direct the electrical heating device advantageously constructed such that the air passage is such opti mized ⁇ by baffles that the noise is minimized.
- the electric heater is advantageous in such a way out forms ⁇ that the fan between the inlet and the Schuele ⁇ element is disposed, wherein the fan is Nals disposed within the Heilka ⁇ such that the distance between the fan and the heating element is sufficiently small, so that this by ei ⁇ ner homogeneous air flow can be flowed through, and the distance is sufficiently large to prevent damage to the fan by heat radiation at temperatures below the two ⁇ th overtemperature.
- the electric heating device is further arranged advantageous that the cross section of the air duct for optimization ⁇ tion of the achievable volume of air flow from the inlet ver ⁇ and tapers toward the outlet is flared.
- Such a configuration allows a comparatively homogeneous and low-vortex and thus also low-noise delivery of the air flow to an environment outside the heater. This applies equally to the absorption of the air flow.
- the electric heating device is further arranged advantageous that the electrical heating device for Signa ⁇ capitalization a fault has a signal / Störtechnisch in the form of a line loop, which is connected up such that it in synchronism with the switching off of the heating element through the first and / or second Over temperature switch is interrupted.
- a fault of the heating device can be signaled to a remote maintenance unit.
- the second overtemperature switch has a further switch which can be triggered together with the switch for switching off the heating element by the switching mechanism and which is connected in such a way that the signal / fault line can be interrupted by it.
- the first over-temperature switch also has two coupled switches, one of which is arranged for switching off the heating element and one for interrupting the signal / interference line.

- the climatic separation can be achieved in a simple manner.
- the formation of the trough, ie the opening with the overlying cover plate to the side of the second housing unit has the advantage that in this way a trough arranged in the interior of the heater is formed and the outer shape of the heater is not changed by the trough.
- the arrangement of the two ⁇ th overtemperature switch in the second, for Anschaltele ⁇ elements provided for housing unit is made possible by such an alignment of the trough.
