Floor care appliance with a plurality of cleaning modes
View Patent ↗A floor care appliance is provided for cleaning bare surfaces such as tile, marble, linoleum and wood. The floor care appliance includes a port for the connection of an accessory hose and wand for off the floor cleaning. A variety of cleaning implements can be attached to the wand for cleaning hard to reach bare surfaces such as tile and grout. The port includes a suction inlet, cleaning solution outlet, and an air turbine inlet for an air turbine pump which pressurizes the cleaning solution. A pivoting door seals the suction inlet, cleaning solution outlet, and air turbine inlet when the accessory hose and wand are not in use.
1. A floor care appliance, comprising:
a main body;
a suction nozzle;
a motor-fan assembly for creating cleaning suction originating at the suction nozzle
a cleaning solution dispensing system;
an air turbine for pressurizing the cleaning solution;
an accessory hose for off the floor cleaning; and
a port located on the main body for fluidly connecting the accessory hose to said air turbine and said motor-fan assembly, the port comprising:
a suction inlet fluidly connected to the motor-fan assembly;
a cleaning solution dispensing outlet fluidly connected to the air turbine; and
an air turbine inlet fluidly connected between the atmosphere and the air turbine.
2. The floor care appliance of claim 1 , further including a pivoting door normally biased by a spring into the closed position for sealing the suction inlet, cleaning solution dispensing outlet and the air turbine inlet when the accessory hose is not in use.
3. The floor care appliance of claim 2 , wherein opening said pivoting door causes said air turbine to pressurize cleaning solution at said cleaning solution dispensing outlet.
4. The floor care appliance of claim 1 , wherein said accessory hose has a connector at one end including:
a solution connector; and
a suction connector;
wherein said solution connector is fluidly connected to said cleaning solution dispensing outlet of said port and said suction connector is fluidly connected to said suction inlet of said port when said accessory hose is connected to said port.
5. The floor care appliance of claim 1 , wherein said accessory hose has a handgrip attached at one end, the handgrip comprised of:
a trigger for selectively dispensing cleaning solution;
a cleaning solution connector;
a suction connector; and
a latch.
6. A port for connecting an accessory hose to a floor care appliance, comprising:
a suction inlet;
a cleaning solution dispensing outlet; and
an air turbine inlet.
7. The port for connecting an accessory hose to a floor care appliance of claim 6 , further including a pivoting door normally biased by a spring into the closed position for sealing the suction inlet, cleaning solution dispensing outlet and the air turbine inlet when the accessory hose is not in use.
8. The port for connecting an accessory hose to a floor care appliance of claim 7 , wherein said pivoting door includes a projection for each of said suction inlet, cleaning solution dispensing outlet and the air turbine inlet for sealing.
9. The port for connecting an accessory hose to a floor care appliance of claim 7 , wherein said pivoting door includes a hook for engaging a catch on said port for securing said door in the closed position.
10. The port for connecting an accessory hose to a floor care appliance of claim 7 , wherein opening said pivoting door exposes said air turbine inlet to the atmosphere and causes an air turbine to pressurize cleaning solution at said cleaning dispensing solution outlet.
