Description

Description
AN ARRANGEMENT IN A CAB OF A VEHICLE
Technical field
[0001] The invention relates generally to vehicles and more specifically to an arrangement in a cab of a vehicle for removing hazardous gas from the cab.
Background art
[0002] In vehicles such as tractors and trucks with sleeping facilities for the driver, gas detectors are installed in the cabs to alert a sleeping driver by sounding an alarm that a hazardous gas, e.g. an anaesthetic gas, has been introduced into the cab of the truck by someone who wants to make the sleeping driver unconscious before robbing him.
[0003] In US 2004/0063394 A1 , it is disclosed that the gas detector upon detecting hazardous gas in the vehicle triggers the fan of the standard ventilation and/or air conditioning system of the vehicle to blow air into the vehicle to reduce the concentration of gas introduced into a vehicle to a harmless value. In addition, the windows of the vehicle can be lowered and the roof hatch of the vehicle can be opened to speed up the air exchange.
[0004] However, by blowing air into the vehicle, the hazardous gas would still remain in the vehicle for some time. Moreover, since the hazardous gas may be introduced via an open window and/or roof hatch, opening them further could worsen the situation.
Disclosure of the invention
[0005] The object of the invention is to quickly remove any detected hazardous gas from a cab of a vehicle.
[0006] This is attained by means of the arrangement according to the invention in a cab of a vehicle, comprising a ventilation and/or air conditioning system with a fan for blowing air into the cab, and a gas detector for detecting hazardous gas in the cab, in that the fan is adapted to operate in reverse to exhaust air from the cab in response to detecting hazardous gas with the help of the gas detector. [0007] This is a simple and inexpensive solution that does not require installation of any additional equipment in the cab.
[0008] In one embodiment, the fan is adapted to operate in reverse at full speed in response to detecting hazardous gas with the help of the gas detector.
[0009] In one embodiment, any open side window of the cab is adapted to be closed in response to detecting hazardous gas with the help of the gas detector.
[0010] In one embodiment, any open roof hatch of the cab is adapted to be closed in response to detecting hazardous gas with the help of the gas detector.
[0011] Hereby, the removal of hazardous gas from the cab will be more effective.
Brief description of the drawings
[0012] The invention will be described more in detail below with reference to the appended drawing on which Fig. 1 is a schematic illustration of a cab of a vehicle with an embodiment of an arrangement according to the invention.
Mode(s) for carrying out the invention
[0013] Fig. 1 is a schematic cross-sectional illustration of a sleeper cab 10 for a vehicle such as a tractor or a truck.
[0014] Even if a sleeper cab is shown in Fig. 1 , it is to be understood that the invention is applicable to any type of cab or passenger compartment.
[0015] In the embodiment in Fig. 1 , the cab 10 comprises a bed 11 for a driver, a side window 12, a roof hatch 13, a standard ventilation and/or air conditioning system 14 with a fan 15 for blowing air into the cab 10, and a gas detector 16 for detecting hazardous gas that is introduced into the cab 10 from the outside e.g. by someone who wants to make a driver sleeping on the bed 11 unconscious before robbing him.
[0016] In a manner known per se, the side window 12, the roof hatch 13 and the fan 15 are operated by respective control motors 17, 18 and 19 in response to respective control signals from a at least one control unit 20 connected to at least one control panel 21 with keys (not shown) by means of which the driver can control the operation of the respective control motor 17, 18 and 19 in a known manner. [0017] Also in a manner known per se, the gas detector 16 is connected to the control unit 20 either directly or indirectly through e.g. a vehicle internal network. Upon detecting hazardous gas in the cab 10, the gas detector 16 is adapted to generate an output signal to the control unit 20.
[0018] In accordance with the invention, the control unit 20, in response to the output signal from the gas detector 16, is adapted to generate an output signal to the control motor 19 instructing the control motor 19 to operate the fan 15 in reverse to exhaust the air filled with hazardous gas from the cab 10.
[0019] In response to the output signal from the gas detector 16, the control unit 20 will preferably instruct the control motor 19 to operate the fan 15 in reverse at full speed.
[0020] In accordance with the invention, the control unit 20, in response to the output signal from the gas detector 16, is adapted to generate an output signal to the control motor 17 instructing it to close the side window 12 and any other side window of the cab 10 should they be open when hazardous gas is detected since the detected gas may be introduced via open side windows. Also, by closing the side windows, the exhaust of hazardous air will be more effective.
[0021] In accordance with the invention, the control unit 20, in response to the output signal from the gas detector 16, is adapted to generate an output signal to the control motor 18 instructing it to close the roof hatch 13 of the cab 10 should the roof hatch 13 be open when hazardous gas is detected since the detected gas may be introduced via the open roof hatch. Also, by closing the roof hatch 13, the exhaust of hazardous air will be more effective.
[0022] Even if a control unit has been described above for controlling the different control motors, it is to be understood that the gas detector equally well can be connected to control the operation of the respective control motors directly.
[0023] In a manner known per se, external lights (not shown) of the vehicle can be caused to flash and an alarm (not shown) can be caused to sound in response to the output signal from the gas detector 16.
