Abstract

The principles and embodiments of the presently claimed invention related to a surface cleaning apparatus, such as a vacuum cleaner, having a wireless communication and control system including two or more wireless radio frequency communication devices configured to transmit and receive control instructions and responses to control the operation of various electrical components disposed within or attached to the surface cleaning apparatus.

Claims

1. A vacuum cleaner comprising:

a handle which comprises,

a partially hollow body,

one or more control features, and

a first wireless radio frequency communication device located within the partially hollow handle body;

a main body;

a suction source;

a suction base that is pivotally or swivelly attached to the main body, and comprises an intake housing having a suction inlet and a discharge opening in fluid communication with the suction source;

a power source configured to be electrically connected to the suction source;

a second wireless radio frequency communication device that is configured to be in communication with the first wireless radio frequency communication device and is configured to control at least the selective application of power to the suction source, wherein the first wireless radio frequency communication device is configured to send wireless signals from the handle to the second wireless radio frequency communication device to control at least the selective application of power to the suction source; and

a rigid support structure that interconnects the handle to the main body.

2. The vacuum cleaner of claim 1, which further comprises, a battery compartment within the partially hollow handle body for receiving a replaceable battery, wherein insertion of a battery into the battery compartment electrically connects the battery to the first communication device which thereby receives a supply of power separate from the power source.

3. The vacuum cleaner of claim 1, wherein the rigid support structure comprises solid struts in physical contact with the hollow handle body.

4. The vacuum cleaner of claim 1, which further comprises a dirt cup removably attached to the main body and in fluid communication with the suction base when so attached;

and wherein the suction source and second communication device are located within the main body.

5. The vacuum cleaners of claim 4, wherein the air path passes from the suction inlet to the dirt cup and then to the suction source.

6. The vacuum cleaner of claim 1, which further comprises a debris receptacle removably attached to the main body and in fluid communication with the suction base when so attached;

and wherein the suction source and second communication device are located within the suction base.

7. The vacuum cleaner of claim 6, wherein the air path passes from the suction inlet to the suction source and then to the debris receptacle.

8. The vacuum cleaner of claim 1, which further comprises a control signal circuit in electrical communication with the first communication device that is configured to generate control signals for transmission from the first communication device to the second communication device.

9. The vacuum cleaner of claim 8, which further comprises

one or more electrical components configured to be electrically connected to the power source;

and

a power control circuit that is configured to receive control signals from the second communication device over an electrical path, and configured to form electrical circuits between the power source and the one or more electrical components.

10. The vacuum cleaner of claim 9;

wherein the power control circuit is configured to selectively apply power to the one or more electrical components in response to signals received from the first communication device.

11. The vacuum cleaner of claim 9;

wherein the power control circuit comprises one or more switches that separately control the formation of electrical circuits between the power source and the one or more electrical components to supply sufficient power to drive the component.

12. The vacuum cleaner of claim 8, which further comprises one or more electrical components;

and

a power control circuit integrated with the power source and configured to receive control signals over an electrical path from the second communication device, and to selectively apply power to the one or more electrical components in response to signals received from the first communication device.

13. The vacuum cleaner of claim 12, wherein the integrated power control circuit and power source is a switching mode power source.

14. The vacuum cleaner of claim 12, wherein the one or more electrical components is selected from the group consisting of electric motors, incandescent lights, LEDs, and

15. The vacuum cleaner of claim 8, wherein the first communication device and the second communication device communicate using a communication protocol;

and the control signal circuit generates digital instructions that includes information to specifically identify the control signal circuit that is transmitted by the transmitter over a particular radio frequency band.

16. The vacuum cleaner of claim 8, wherein the one or more control features are configured to provide input to the control signal circuit to control the mode of operation of the vacuum cleaner.

17. The vacuum cleaner of claim 16, wherein the control features on the handle can control the operation of one or more of an electric motor speed, a brush roll rotation, a light, an LED, the suction base height, and air path diverter positioning.

18. The vacuum cleaner of claim 17, wherein the control signal circuit generates unique digital instruction codes to control the operation of one or more of an electric motor speed, brush roll rotation, a light, an LED, the suction base height, and air path diverter positioning,

19. The vacuum cleaner of claim 17, wherein the instruction codes are communicated from the first communication device to the second communication device to selectively apply power to the one or more electrical components in response to signals received from the first communication device, and the second communication device sends a response to the first communication device acknowledging the application of power to the one or more electrical components,

20. The vacuum cleaner of claim 17, which further comprises a third wireless communication device configured to provide control signals to the power source over an electrical path, wherein the second wireless communication device and the third wireless communication device communicate with the first wireless communication device over different radio frequency bands, and the second wireless communication device is configured to receive control signals for a subset of electrical components different and separate from a subset of electrical components that selectively receive power in response to signals received at the third wireless communication device.

21. The vacuum cleaner of claim 17, wherein the subset of electrical components configured to receive control signals over the second wireless communication device includes a suction motor, a headlight, and a brushroil motor;

and

the subset of electrical components configured to receive control signals over the third wireless communication device includes an attachment device affixed to a distal end of a suction wand.
