Abstract

Embodiments of the invention disclosed herein include steam appliances and methods which apply steam and a liquid containing a cleaning agent to the floor via separate outlets. In some embodiments, the liquid containing a cleaning agent is applied to an area of the floor that is physically separated from a steam application area. The steam may be applied to the floor through a steam-permeable fabric. The liquid containing a cleaning agent may be heated before being applied to the floor or being mixed with steam.

Claims (47)

1. A steam cleaning appliance for cleaning floors comprising:

an appliance body;

a handle attached to the appliance body;

a liquid applicator to apply a first liquid to a floor;

a steam source to generate steam; and

a cleaning head to apply steam to the floor; wherein

movement of the handle in a forward and/or backward motion to move the cleaning head on the floor operates a liquid delivery system to deliver a second liquid to the steam source; and further comprising

a controller and a lock configured to automatically prevent delivery of the second liquid to the steam source in response to the steam cleaning appliance being disconnected from a power source.

2. A steam cleaning appliance as in claim 1 , further comprising:

a first reservoir to hold the first liquid, the liquid applicator being in communication with the first reservoir; and

a second reservoir to hold the second liquid, the steam source being in communication with the second reservoir.

3. A steam cleaning appliance as in claim 2 , wherein:

the handle is movably attached to the appliance body;

movement of the handle in a forward and/or backward motion to move the cleaning head results in a movement of the handle relative to the cleaning head, which movement pumps the second liquid from the second reservoir to the steam source; and

the controller comprises an obstruction which prevents movement of the handle relative to the cleaning head.

4. A steam cleaning appliance as in claim 1 , wherein the first liquid is different from the second liquid.

5. A steam cleaning appliance as in claim 1 , further comprising a steam-permeable cleaning pad mounted to the cleaning head, wherein the cleaning head is configured to apply steam to the floor through the pad.

6. A steam cleaning appliance as in claim 1 , wherein a solenoid is de-energized to automatically prevent delivery of the second liquid to the steam source in response to the steam cleaning appliance being disconnected from the power source.

7. A steam cleaning appliance as in claim 1 , wherein the controller is configured to automatically prevent delivery of the second liquid to the steam source in response to a temperature sensor detecting a sensed temperature of the steam source being below a threshold temperature.

8. A steam cleaning appliance as in claim 1 , wherein the liquid applicator includes an electric pump.

9. A steam cleaning appliance for cleaning floors comprising:

an appliance body;

a handle attached to the appliance body;

a liquid applicator to apply a first liquid to a floor;

a steam source to generate steam; and

a cleaning head to apply steam to the floor; wherein

movement of the handle in a forward and/or backward motion to move the cleaning head on the floor operates a liquid delivery system to deliver a second liquid to the steam source; and further comprising

a controller and a lock configured to automatically prevent delivery of the second liquid to the steam source in response to the steam cleaning appliance being disconnected from a power source and/or a temperature sensor detecting a sensed temperature of the steam source being below a threshold temperature, wherein the lock is configured to prevent pushing and/or pulling movement of the handle relative to the appliance body and/or cleaning head in response to the steam cleaning appliance being disconnected from the power source and/or the temperature sensor detecting the sensed temperature of the steam source being below the threshold temperature.

10. A steam cleaning appliance as in claim 9 , wherein the lock includes a plunger configured to be received in an opening to prevent pushing and/or pulling movement of the handle relative to the appliance body and/or cleaning head in response to the steam cleaning appliance being disconnected from the power source and/or the temperature sensor detecting the sensed temperature of the steam source being below the threshold temperature.

11. A steam cleaning appliance comprising:

a handle;

a liquid applicator fluidly coupled to a first reservoir and configured to dispense a first liquid;

a steam generator fluidly coupled to a second reservoir and configured to generate steam;

a cleaning head to dispense steam from the steam generator;

a manually actuable pump to move a second liquid from the second reservoir to the steam generator in response to movement of the handle during pushing and/or pulling of the steam cleaning appliance; and

a controller and a lock configured to automatically prevent delivery of the second liquid to the steam source in response to the steam cleaning appliance being disconnected from a power source.

12. A steam cleaning appliance as in claim 11 wherein a solenoid is de-energized to automatically prevent delivery of the second liquid to the steam source in response to the steam cleaning appliance being disconnected from the power source.

13. A steam cleaning appliance as in claim 11 , wherein the controller is configured to automatically prevent delivery of the second liquid to the steam source in response to a temperature sensor detecting a sensed temperature of the steam source being below a threshold temperature.

14. A steam cleaning appliance as in claim 11 , wherein the liquid applicator includes an electric pump.

15. A steam cleaning appliance comprising:

a handle;

a liquid applicator fluidly coupled to a first reservoir and configured to dispense a first liquid;

a steam generator fluidly coupled to a second reservoir and configured to generate steam;

a cleaning head to dispense steam from the steam generator;

a manually actuable pump to move a second liquid from the second reservoir to the steam generator in response to movement of the handle during pushing and/or pulling of the steam cleaning appliance; and

a controller and a lock configured to automatically prevent delivery of the second liquid to the steam source in response to the steam cleaning appliance being disconnected from a power source and/or a temperature sensor detecting a sensed temperature of the steam source being below a threshold temperature, wherein the lock is configured to prevent pushing and/or pulling movement of the handle in response to the steam cleaning appliance being disconnected from the power source and/or the temperature sensor detecting the sensed temperature of the steam source being below the threshold temperature.

16. A steam cleaning appliance as in claim 15 , wherein the lock includes a plunger configured to be received in an opening to prevent pushing and/or pulling movement of the handle in response to the steam cleaning appliance being disconnected from the power source and/or the temperature sensor detecting the sensed temperature of the steam source being below the threshold temperature.
