Abstract

A central vacuum cleaning system including a receptacle for receiving dirt; conduits terminating in valves to which a flexible hose may be attached; a motor for generating airflow through the conduits to the receptacle; a motor control circuit controlling power to the motor; and a remote module receiving, through a communications medium from the motor control circuit, signals indicating an operating condition of the central vacuum cleaning system.

Claims

1. A central vacuum cleaning system comprising:

(i) a vacuum source including;

a motor within a motor housing,

a receptacle extending from the motor housing for receiving dirt, and

a motor control circuit including a variable speed controller for adjusting a speed of the motor;

(ii) one or more valves;

(iii) conduits for connecting to the vacuum source to the valves;

(iv) a handle to be held by an operator, a flexible hose for releasably connecting the handle to one of the one or more valves, and a cleaning attachment connected to the handle, such that when the motor is activated during use of the system, dirt is drawn by a vacuum created by the vacuum source through the attachment, handle, hose, and conduits, and into the receptacle;

(v) a user display at a display location on the handle for displaying information about an operating condition of the vacuum source;

(vi) a user input interface at an input location on the handle for adjusting an operating speed of the motor control circuit;

(vii) a communications system to transfer control signals from the user input interface to the variable speed controller of the motor control circuit to adjust the speed of the motor wherein the communications system comprises an RF wireless transmitter in the handle, and an RF wireless receiver at the motor control circuit.

2. The central vacuum cleaning system of claim 1, comprising:

a sensor for sensing an operating condition of the motor; and

a remote module receiving, through a wireless communications medium from the motor control circuit, signals indicating the operating condition of the central vacuum cleaning system, the remote module being a wireless module located remote from both the motor control circuit and from the handle.

3. The system of claim 2 wherein the remote module is a microprocessor enabled portable wireless module.

4. The system of claim 2 wherein the remote module is adapted to be mounted to a wall.

5. The system of claim 2 wherein the communications medium is a bi-directional medium, the remote module being configured to provide control signals to the motor control circuit in response to user input at the remote module.

6. The system of claim 2 wherein the remote module is configured to communicate with a plurality of automated functions located within a building that the system is located within.

7. The system of claim 2 wherein the remote module includes a user interface for receiving user input and providing corresponding control signals over the communications medium to the motor control circuit, the motor control circuit being responsive to a predetermined control signals to adjust an operating speed of the motor in response to user inputs at the user interface.

8. The system of claim 7 wherein the user interface includes a variable speed control input for adjusting the operating speed of the motor between a plurality of running speeds.

9. The system of claim 2 wherein the user interface and the user input interface each includes a respective touch screen display.

10. The system of claim 1 including a microprocessor enabled wireless, portable control module for controlling the motor control circuit, the portable control module comprising:

a transceiver for exchanging signals over a wireless communications medium;

a screen for displaying information regarding one or more operating conditions of the central vacuum cleaning system in dependence on signals received through the transceiver;

a user interface for receiving user inputs and providing signals to the transceiver for transmission to the motor control circuit in dependence thereon.

11. The system of claim 10 wherein the user interface is integrated into the screen as a touch screen.

12. The system of claim 10 wherein the portable control module is located apart from any other component of the central vacuum cleaning system.

13. The system of claim 12 wherein the portable control module is configured to perform multiple functions unrelated to the central vacuum cleaning system.

14. The system of claim 10 wherein the portable control module is configured to provide signals to the motor control circuit requesting information therefrom.
