Abstract

A portable heater includes a housing having an air inlet and an air outlet, one or more burners housing within the housing and configured to heat air passing through the housing from the air inlet to the air outlet, and a duct positioned in a storage compartment of the housing. The duct includes a first end coupled to the storage compartment and a second end extendable from the housing when a door of the storage compartment is in an open position.

First claim

What is claimed is:

1. A portable heater comprising:
a housing comprising an air inlet and an air outlet;
one or more burners housed within the housing and configured to heat air passing through the housing from the air inlet to the air outlet;
a storage compartment comprising a bottom wall and a side wall each pivotably coupled to the housing, the side wall forming an outer side surface of the portable heater; and
a duct positioned in the storage compartment of the housing, the duct comprising a first end coupled to the bottom wall and a second end extendable from the housing when a door of the storage compartment comprising the side wall is in an open position, the duct configured to pivot along with the bottom wall.

2. The portable heater of claim 1 , wherein the bottom wall is substantially horizontal when the door is in a closed position and substantially vertical when the door is in the open position.

3. The portable heater of claim 2 , wherein the duct extends in a substantially perpendicular direction from the bottom wall.

4. The portable heater of claim 3 , wherein the duct is configured to expand from a first length to a second length, the first length being less than a height of the storage compartment, and the second length being longer than a height of the storage compartment.

5. The portable heater of claim 2 , further comprising a hinge coupling the door to the housing.

6. The portable heater of claim 5 , wherein the door is configured to rotate from the open position to the closed position when the second end of the duct is pushed toward the first end of the duct.

7. The portable heater of claim 1 , wherein the side wall of the door is configured to form at least a portion of a ramp when the door is in the open position, the ramp configured to support the duct.

8. The portable heater of claim 7 , wherein the door further comprises a top wall pivotably coupled to the side wall, wherein the top wall forms a top of the storage compartment when the door is in a closed position and forms a portion of the ramp when the door is in the open position.

9. The portable heater of claim 1 , wherein the door comprises a top wall coupled to the side wall, wherein the side wall forms a portion of a side of the housing, and the top wall forms a portion of a top of the housing.

10. The portable heater of claim 9 , wherein the duct is configured to be condensed to fit in the storage compartment between the top wall and the bottom wall when the door is in a closed position.

11. A portable heater comprising:
a housing comprising a storage compartment, a door providing access to the storage compartment and comprising a window, an air inlet, and an air outlet;
a burner housed within the housing and configured to heat air passing through the housing from the air inlet to the air outlet;
a generator positioned in the storage compartment and selectively providing power to the burner;
a controller operably coupled to and configured to control operation of the burner and operation of the generator; and
a user interface positioned in the storage compartment and operably coupled to the controller and configured to receive inputs from an operator, wherein the controller is configured to control a supply of power from the generator to the burner based on an input from the user interface, wherein the user interface is aligned with and viewable through the window from outside the housing.

12. The portable heater of claim 11 , wherein the controller is configured to control the user interface to indicate a status of the portable heater based on a color of the user interface.

13. The portable heater of claim 11 , wherein the controller is configured to provide status information and performance information about the portable heater to the user interface for display.

14. The portable heater of claim 13 , wherein the status information and performance information comprise at least one of an operating temperature of the burner, a burner output, a generator output, an operating pressure of the burner, an engine speed of the generator, or a fuel level of the generator or the burner.
