Forced air heater including on-board source of electric energy
A forced-air heater having a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source; a fuel tank; a combustion chamber; a support; a housing including upper and lower housing portions; a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber.
1. A forced-air heater comprising:
a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source wherein the on-board electric power supply has a charge capacity per unit area of positive and negative electrodes of at least 0.75 mA-h/cm2;
a fuel tank;
a combustion chamber;
a support;
a housing including upper and lower housing portions;
a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber.
2. The forced-air heater of claim 1 , further comprising:
an electric energy outlet that interfaces with an electric accessory to energize the electric accessory.
3. A forced-air heater comprising:
a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source;
a negative electrode of the on-board electric power supply having a specific impedance of less than or equal to about 2.5 Ω-cm2;
a fuel tank;
a combustion chamber;
a support;
a housing including upper and lower housing portions;
a motorized fan that during operation draws in ambient though an air intake and forces air into the combustion chamber.
4. The forced-air heater of claim 1 , further comprising:
a rectifier to distribute direct current electric energy to the heater.
5. The forced-air heater of claim 1 , further comprising:
an inverter to distribute alternating current electric energy to the heater.
6. The forced-air heater of claim 1 , further comprising:
a control unit to establish and break conductive pathways to activate and deactivate electric components.
7. The forced-air heater of claim 1 , further comprising:
at least one light source coupled to the heater.
8. The forced-air heater of claim 1 , further comprising:
a heater control panel operatively coupled with a thermostat control and an ignition switch.
9. A forced-air heater comprising:
a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source wherein the on-board electric power supply has a specific impedance of less than about 16 Ω-cm2;
a fuel tank;
a combustion chamber;
a support;
a housing including upper and lower housing portions;
a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber.
10. A forced-air heater comprising
a self-contained on-board electric-power supply that allows the forced-air heater to operate without an external electric power source;
a fuel tank;
a combustion chamber;
a support;
a housing including upper and lower housing portions;
a motorized fan that during operation draws in ambient air through an air intake and forces air into the combustion chamber;
a chassis that enables mobility;
at least one wheel positioned within a wheel well formed in the fuel tank; and
a frame having a cross member that can serve as a handle which allows an operator to grasp the forced-air heater and maneuver it.
11. The forced-air heater of claim 10 , further comprising:
a rain shield that interferes with the entry of falling objects or other debris into an end of a heating conduit while the heater is in an upright storage position.
12. The forced-air heater of claim 10 , wherein the on-board electric-power supply is selected from the group consisting of a battery, a thermoelectric generator, a fuel cell, and an ultracapacitor.
13. The forced-air heater of claim 10 , wherein the on-board electric-power supply is a lithium secondary cell battery or lithium ion battery.
