Title of Invention

AIR HEATER FOR HEATING PASSENGER COMPARTMENTS OF MOTOR VEHICLES AND FOR DEFROSTING WINDSCREENS OF VEHICLES

Abstract The invention relates to an instantaneous air-heating unit. The invention comprises a hot air (2) intake hood (1) which is disposed partially against the exhaust gas collectors (3) of the engine (4) of the vehicle, preferably when the vehicle is being started. According to the invention, an air duct (5) connects the aforementioned hood to a small turbine (6) or an extractor which drives the air to the enclosure (8), the front and rear windows (9) or the outside rear-view mirrors (10) through one or more suitable ducts (7). Moreover, a thermostat (11) is used to shut down the instantaneous heating and start up the standard heating using a manual or electric butterfly valve (12), thereby stopping the turbine (6).

INSTANTANEOUS AIR-HEATING UNIT DESCRIPTION
OBJECT OF THE INVENTION
[0001]The present invention refers to an instant air heater from amongst those means for heating small areas, particularly passenger compartments of motor vehicles, and for defrosting their screens.
[0002]This invention is characterised by a bell-housing semi-attached to the exhaust fume manifold during vehicle starting, a unit that forces the air into the compartment, with disconnection means for switching off this instant heating and switching over to conventional heating, plus a CO2 detector which stops the turbine or acts as a butterfly valve for cutting off the air flow and activates a warning light and/or buzzer.
BACKGROUND OF THE INVENTION
[0003]The problems arising from cold, which may actually reach the inside of motor vehicles in extreme circumstances, even force these vehicles to be provided with double glazing and, in general, make driving disagreeable or
uncomfortable and are not remedied in the course of short trips merely by
driving.
[0004]The applicant is unaware of the existence of other means that will remedy the afore-mentioned problems with the simplicity and efficiency of the
invention, which is now going to be described.

DESCRIPTION OF THE INVENTION
[0005]The present invention refers to an instant air heater from amongst those heating means, preferably of motor vehicle passenger compartments and, on a supplementary basis, for defrosting their screens.
[0006]This invention is characterised by a special construction of a bell housing for collecting hot air in an arrangement semi-attached to the vehicle exhaust fume manifold, set up to operate during the vehicle start-up time.
[0007]An air hose links it to a small turbine or an extractor fan which, by way of a suitable pipe or pipes, forces the air into the area to be heated and/or to the element that requires a higher temperature, such as for instance the front and rear screens, as well as the exterior rear view mirrors.
[0008]The assembly also has disconnection means for switching off this instant heating and switching over to conventional heating, consisting for example of a butterfly valve operated conventionally by manual, electrical or other means.

[0009]Lastly, it is provided with a CO2 detector that shuts off the turbine or extractor which operates the air flow shut-off valve and which activates a warning light and/or buzzer on a redundant basis.
DESCRIPTION OF THE DRAWINGS
[0010]The present descriptive report is supplemented with a set of drawings illustrating the preferred embodiment and never limiting the scope of the invention.

PREFERRED EMBODIMENT OF THE INVENTION
[0011]ln view of what is stated above, the present invention refers to an instant air heater, from amongst the means for the heating of motor vehicle passenger
compartments and for defrosting their screens, essentially characterised in that they are made up of a bell-housing (1) for collecting the hot air (2), semi-attached to the exhaust gas outlet manifolds (3) of the engine (4) of the vehicle, preferably while it is being started, linked by an air hose (5) to a small turbine (6) or an extractor which forces the air into the compartment (8), to the front
and rear screens (9) or the exterior rear view mirrors (10) by way of a suitable pipe (7) or several of these.
[0012]The assembly uses a thermostat (11) to shut off the instant heating and opens up the conventional heating by means of a manual or electrically-operated butterfly valve (12), stopping the turbine (6) and, alternatively a CO2 detector (13) which, besides shutting off the latter when pre-set temperatures are reached, activates a warning light and/or buzzer (14), which may or may not be controlled by a central electronic unit (15).

[0013]The essential nature of this invention is not altered by variations in materials, shape, size and arrangement of the component parts, described on a non-restrictive basis, in such a way that this explanation may suffice for the invention to be reproduced by an expert.

CLAIMS
1.- Instant air heater from amongst those means for heating the passenger compartments of motor vehicles and for defrosting their screens, essentially characterised in that it includes:
- a bell housing (1) for collecting the hot air (2), semi-attached to the exhaust
fume output manifolds (3) of the vehicle engine (4), preferably during
starting, linked by
- an air hose (5) to
- a small turbine (6) or an extractor which, by way of
- a suitable pipe (7) or several of these, forces the air into the compartment
(8), to the front and rear screens (9) or the exterior rear view mirrors (10).
- a thermostat (11) for shutting off the instant heating and opening up the
conventional heating by means of
- a manual or electrically-operated butterfly valve (12), stopping the turbine
(6).
2.- Instant air heater, according to the previous claim, characterised in that, on a complementary basis to the thermostat (11) and when pre-set temperature levels are reached, a CO2 detector (13) activates a warning light and/or buzzer (14) in the compartment (8).
3.- Instant air heater, according to the previous claims, characterised in that it includes a central electronic unit (15) for controlling the installation.
