Abstract
The utility model relates to an electric fan heater, railroad locomotive is electric fan heater for cab specifically says so. It includes there is hot air exitus by the casing on the lateral wall of casing, there is electric heater in the position department that corresponds hot air exitus in the casing, and electric heater's rear side has the fan. Its characteristics are there is rotary encoder on the fan, there is the controller in the casing, electric heater and rotary encoder all link to each other with the controller through the wire. The incident because of the high temperature in the electric fan heater casing causes during the motor bring to rest, can be avoided taking place fan motor trouble to this electric fan heater.
Description
Technical field
The utility model relates to a kind of heater unit, is railway locomotive cab heater unit specifically.
Background technology
All know in the industry at railway motorcycle, in order to the winter in cold provides comfortable working environment to the bus attendant in driver's cab, in the driver's cab of railway locomotive, usually all heater unit can be installed.
At present, the railway locomotive cab heater unit used in industry comprises housing, and the sidewall of housing has hot-blast outlet, and in housing, there is electric heater the position of corresponding hot-blast outlet, and the rear side of electric heater has blower fan.During use, be first all connected with the power supply in driver's cab by wire with blower fan by electric heater, then start electric heater and blower fan simultaneously, electric heater is by the air heating in housing, and blower fan by the hot air blowout in housing, thus forms warm braw.Because on locomotive, power network voltage is extremely unstable, voltage is through 175V---320V interval fluctuation of being everlasting, so easily there is blower motor fault in heater unit, motor is out of service, the situation that electric heater is also working on, thus the heat making electric heater produce cannot distribute in time in heater unit housing, the temperature in heater unit housing is too high, very easily causes safety misadventure.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of railway locomotive cab heater unit, and this heater unit, in generation blower motor fault, when motor is out of service, can avoid the safety misadventure caused because the temperature in heater unit housing is too high.
For solving the problem, provide following technical scheme:
Railway locomotive cab heater unit of the present utility model comprises housing, and the sidewall of housing has hot-blast outlet, and in housing, there is electric heater the position of corresponding hot-blast outlet, and the rear side of electric heater has blower fan.Be characterized in that described blower fan has rotary encoder, have controller in described housing, described electric heater is all connected with controller by wire with rotary encoder.
Wherein, described electric heater has temperature sensor, this temperature sensor is connected with described controller by wire.
Take above scheme, have the following advantages:
Blower fan due to railway locomotive cab heater unit of the present utility model has rotary encoder, has controller in described housing, described electric heater is all connected with controller by wire with rotary encoder.So operationally, when blower motor fault, when motor is out of service, rotary encoder detects that the working speed information of blower motor is zero, and convert this information to electric signal transmission to controller, it is out of service that controller controls electric heater, makes the temperature in heater unit housing can not continue to raise, thus avoid the safety misadventure caused because the temperature in heater unit housing is too high.
Accompanying drawing explanation
Fig. 1 is the structural representation of railway locomotive cab heater unit of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, railway locomotive cab heater unit of the present utility model comprises housing 1, the sidewall of housing 1 is processed with hot-blast outlet 2, and in housing 1, the position of corresponding hot-blast outlet 2 is provided with electric heater 3, and the rear side of electric heater 3 is provided with blower fan 4.Described blower fan 4 is provided with rotary encoder 5, described electric heater 3 is provided with temperature sensor 7, be provided with controller 6 in described housing 1, described electric heater 3, temperature sensor 7 are all connected with controller 6 by wire with rotary encoder 5.
Temperature value for detecting the temperature of electric heater 3, and is converted to electric signal transmission to controller 6 by described temperature transmitters.
Described rotary encoder 5 for detecting the working speed of blower fan 4 motor, and converts working speed value to electric signal transmission to controller 6.
Described controller 6 runs for controlling electric heater 3 or stops, and when the temperature value that controller 6 receives is zero higher than the rotating speed of pre-set threshold value or blower fan 4 motor, controller 6 control heater is out of service.When the temperature value that controller 6 receives is non-vanishing higher than the rotating speed of pre-set threshold value or blower fan 4 motor, controller 6 controls electric heater 3 and keeps running.
