Method for controlling a vacuum cleaner or a central vacuum cleaner
First Claim
1. A method for controlling a central vacuum cleaner comprising a central machinery and a pipe system connecting said central machinery with a working point, in which method the central machinery is controlled in a wireless manner using the pipe system of the device as a transmission channel, comprising for the start-up of the central machinery the steps oftransmitting sound or pressure impulses from the working point;
- detecting said impulses with an acoustic sensor; and
starting the central machinery in response to the detection of the acoustic sensor;
and for the stopping of the central machinery the steps ofblocking the flow in the pipe system;
detecting the stopping of the flow by means of a flow sensor; and
stopping the central machinery in response to the detection of the flow sensor.

Abstract
The invention relates to a method of control for a device such as a vacuum cleaner or a central vacuum cleaner comprising a central machinery and a pipe or a pipe system connecting the central machinery with a working point. In order to avoid the installation of control conductors connecting the working points with the central machinery, the operation of the central machinery is controlled according to the invention in a wireless manner by means sound or pressure impulses transmitted from the working point to a receiving sensor using the pipe or the pipe system of the device as a transmission channel, whereby for the start-up of the central machinery, sound or pressure impulses are transmitted from the working point; said impulses are detected with an acoustic sensor; and the central machinery is started in response to the detection of the acoustic sensor; and for the stopping of the central machinery, the flow in the pipe system is blocked; the stopping of the flow is detected by means of a flow sensor; and the central machinery is stopped in response to the detection of the flow sensor.

8. A system for controlling a central vacuum cleaner comprising a central machinery and a pipe arrangement connecting said central machinery with a working point, said central machinery being controlled in a wireless manner using the pipe arrangement as a transmission channel, comprising:
-
means for transmitting sound or air pressure impulses from the working point to start up said central machinery; means including a sensor for detecting said impulses; means responsive to said detection means for starting said central machinery in response to the detection of energy by said sensor; means for stopping of said central machinery including means for blocking the flow of air in said pipe arrangement; means including an air flow sensor for detecting the stopping of the flow of the air in said pipe by said flow sensor; and means for stopping said central machinery in response to the detection of air flow stoppage in said pipe by said flow sensor. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
