Definitions

  • the present invention concerns a control system for a vacuum cleaner.
  • vacuum cleaner control systems comprise one or more user-operable controls, such as push-button switches, which control the operation of such features of the vacuum cleaner as a main suction source of the vacuum cleaner or a rotatable brush mounted in a floorhead of the vacuum cleaner, independently of each other.
  • An example of such a vacuum cleaner control system is described in GB-A-2 436 789 .
  • this allows a user to select which features of the vacuum cleaner to operate as desired, but on the other, it may also be damaging to the vacuum cleaner, by allowing different features of the vacuum cleaner which have an adverse effect on the vacuum cleaner and/or on each other during their simultaneous operation to be switched on at the same time. This is particularly important in the case of a battery powered vacuum cleaner, where the simultaneous operation of several different unrelated features of the vacuum cleaner may place an undue load on the battery.
  • the present invention provides a vacuum cleaner control system comprising: a first user-operable control for switching a suction source of said vacuum cleaner between an on condition and an off condition; a second user-operable control for switching a rotatable brush in a floorhead of said vacuum cleaner between an on condition and an off condition; a third user-operable control for switching a filter cleaning mechanism for cleaning a filter of said vacuum cleaner between an on condition and an off condition; a detector for detecting when a handle of said vacuum cleaner is tilted between a substantially vertical, storage position and an angled, use position; and an electronic circuit for receiving input signals from said first, second and third user-operable controls and from said detector, said electronic circuit having a first output for switching said suction source on and off, a second output for switching said floorhead brush on and off and a third output for switching said filter cleaning mechanism on and off.
  • the electronic circuit may be programmed to switch different features of the vacuum cleaner on and off to suit the efficient and effective operation of the vacuum cleaner, without permitting the user to perform operations which would tend to damage the vacuum cleaner or its components, or in the case of a battery-powered vacuum cleaner, place undue load on the battery.
  • the vacuum cleaner control system of the present invention further comprises a display, and the electronic circuit further comprises an output for driving said display, and said display comprises an input for receiving said output from said electronic circuit.
  • control system further comprises an interlock switch for detecting when a cover of said floorhead is removed, said interlock switch having an output, wherein said electronic circuit further comprises an input for receiving said output from said interlock switch.
  • the electronic circuit may be programmed to disable operation of the floorhead brush when the cover of the floorhead is removed, thereby enhancing the safety of the user.
  • the first, second and third user-operable controls of the control system should be located on the handle of the vacuum cleaner. If this is not possible because of the overall design of the vacuum cleaner, it is again desirable, but less so, that a majority (i.e. two) of the first, second and third user-operable controls should be located on the handle of the vacuum cleaner.
  • the control system comprises a display
  • at least one of the first, second and third user-operable controls should also preferably be integrated into the display for improved user convenience and ergonomics.
  • the detector detects that the handle of the vacuum cleaner is in the substantially vertical, storage position, switching on of said floorhead brush by said electronic circuit is disabled.
  • This helps to conserve battery power in the event that the vacuum cleaner is battery-powered, and also ensures that the floorhead brush is not allowed to rotate in a fixed location, which could damage a floor covering, such as a carpet, in that location.
  • This desirable feature of the detector may best be achieved by placing the detector in series with the second user-operable control.
  • a vacuum cleaner 10 comprising a control system according to a preferred embodiment of the invention.
  • the vacuum cleaner 10 has a handle 12, a suction source 14 comprising a primary motor and a fan, a dust collection chamber 16 containing a filter assembly 18, a secondary motor 20 for operating a filter cleaning mechanism for cleaning the filter assembly 18, a floorhead 22 comprising a rotatable brush 24 driven by a third motor 26, and a removable and rechargeable battery pack 28 for supplying power to the vacuum cleaner.
  • the vacuum cleaner also comprises a removable wand 29 which can be used for cleaning above floor level instead of the floorhead 22.
  • a changeover valve is switched to divert the flow of air drawn into the vacuum cleaner by the suction source 14 from the floorhead 22 to the mouth of the wand 29.
  • Such automatic changeover valves are well known in vacuum cleaners.
  • the vacuum cleaner control system itself comprises a series of first, second and third user-operable controls 30, 32, 34 in the form of push-button switches located on the handle 12 of the vacuum cleaner, a display 36 having the first and second user-operable controls formed integrally therein, a detector 38 in the form of a tilt switch for detecting when the handle 12 of the vacuum cleaner is tilted between a substantially vertical, storage position and an angled, use position, an electronic circuit 40 for receiving input signals from the first, second and third user-operable controls 30, 32, 34 and from the detector 38 and an interlock switch 42 for detecting when a cover of the floorhead 22 is removed.
  • the interlock switch 42 is placed in series with the third motor 26 so that when the interlock switch detects that the cover of the floorhead has been removed by a user, for example to clean the brush 24, the supply of power to the third motor 26 from the battery pack 26 is interrupted and the third motor 26 is unable to cause the brush 24 to rotate.
  • Electrical connections between the various components of the vacuum cleaner control system are represented schematically in Fig. 1 by lines connecting these various components.
  • FIG. 2 This shows how the electronic circuit 40 of the vacuum cleaner control system is in the form of a microcontroller and that in addition to it receiving a clock signal, it also receives input signals from the first, second and third user-operable controls 30, 32, 34 and from the detector 38.
  • the detector 38 is placed in series with the second user-operable control 32, such that when the detector 38 detects that the handle 12 of the vacuum cleaner is in a substantially vertical, storage position, switching on of the floorhead brush 24 by the electronic circuit 40 is disabled.
  • the electronic circuit 40 also has an input receiving an output signal from a battery charge level sensor in the form of a voltage bridge across the terminals 44, 46 of the battery pack 28.
  • the voltage bridge is set such that when the output signal therefrom reaches a predetermined level, the electronic circuit 40 sends an output to the display 36 causing the display to display low-battery indicia.
  • the electronic circuit 40 has a first output for switching the suction source 14 on and off, a second output for switching the floorhead brush motor 26 on and off and a third output for switching the motor 20 which drives the filter cleaning mechanism on and off. Further outputs of the electronic circuit 40 send signals to the display 36 in a manner which will be better understood by reference to the following description which is given in association with Figs. 3 to 8 .
  • FIG. 3 there is shown a flow diagram of the operation of the vacuum cleaner control system in a storage mode thereof, for example when the vacuum cleaner is put by a user in a cupboard or closet.
  • operation by a user of the first, second and third user-operable controls 30, 32, 34 to the off condition very simply causes the electronic circuit 40 to switch off the suction source 14, the secondary motor 20, the third motor 26 and the display 36.
  • Fig. 4 there is shown a flow diagram of the operation of the vacuum cleaner control system when a user takes the vacuum cleaner out of the cupboard or closet ready for use and operates the first user-operable control 30.
  • operation by the user of the first user-operable control 30 to the on condition causes the electronic circuit 40 to switch the suction source 14 on and to send an output to the display 36 causing the display to display power-on indicia.
  • detector 38 since the handle 12 of the vacuum cleaner is still in the substantially vertical, storage position, detector 38 also relays a signal to electronic circuit 40 which conveys this fact, with the result that even if the user operates the second user-operable control 32 to the on condition, switching on of the floorhead brush 24 by the electronic circuit 40 is disabled. This helps to conserve battery power when the user has not adjusted the handle 12 of the vacuum cleaner to an angled, use position.
  • operation by the user of the first user-operable control 30 to the off condition causes the electronic circuit 40 to switch both the suction source 14 and the power-on indicia displayed by the display 36 off again.
  • Fig. 5 is a flow diagram showing what happens when the user adjusts the handle 12 of the vacuum cleaner to an angled, use position.
  • operation by the user of the first user-operable control 30 to the on condition causes the electronic circuit 40 to switch both the suction source 14 and the display 36 on as before.
  • detector 38 relays a signal to electronic circuit 40 which conveys this fact, with the result that if the user operates the second user-operable control 32 to the on condition, switching on of the floorhead brush 24 by the electronic circuit 40 is now enabled.
  • a user may switch the floorhead brush 24 on and off by operating the second user-operable control 32 to the on or off condition respectively, as desired.
  • operation by the user of the first user-operable control 30 to the off condition causes the electronic circuit 40 to switch both the suction source 14 and the display 36 off again, but also to switch the floorhead brush .24 off again as well.
  • FIGs. 4 and 5 show what happens when the removable wand 29 is in its storage position on the vacuum cleaner.
  • Figs. 6 and 7 show flow diagrams of the operation of the vacuum cleaner control system when the wand is removed from its storage position by a user, for example to perform cleaning above floor level, thereby causing the automatic changeover valve to divert the flow of air drawn into the vacuum cleaner by the suction source 14 from the floorhead 22 to the mouth of the wand 29, as already described above.
  • Figs. 6 and 7 respectively show the operation of the vacuum cleaner control system when the handle 12 is still in the substantially vertical, storage position and when the handle 12 is in the angled, use position, so that Fig. 6 corresponds to Fig. 4 and Fig. 7 corresponds to Fig.
  • Fig. 8 shows a flow diagram of the operation of the vacuum cleaner control system in a filter-cleaning mode thereof, in other words, what happens when a user operates the third user-operable control 34 to an on condition.
  • the operation of the vacuum cleaner control system in this mode depends upon whether or not the suction source 14 is on, in other words, on whether or not a user has previously switched the first user-operable control 30 to the on condition thereof.
  • the electronic circuit 40 switches the filter cleaning mechanism 20 on for a predetermined period of time, for example for 10 seconds, and then switches the filter cleaning mechanism off again.
  • the electronic circuit 40 also sends an output to the display 36 causing it to display filter-cleaning indicia for the period of time that the filter cleaning mechanism is on.
  • the electronic circuit 40 also continues to cause the display 36 to display filter-cleaning indicia for a short while longer after the filter cleaning mechanism has been switched off again, thereby incorporating a delay before the vacuum cleaner returns to its storage mode in which the suction source 14, the secondary motor 20, the third motor 26 and the display 36 are all switched off. This delay helps to discourage a user from starting up the suction source 14 again whilst the motor 20 of the filter cleaning mechanism is still running down.
  • the electronic circuit 40 switches the suction source 14 off and also checks whether the third motor 26 driving the floorhead brush 24 is on. If it finds that the third motor 26 is on, the electronic circuit 40 also switches the third motor 26 off before switching the filter cleaning mechanism 20 on for a predetermined period of time, for example for 10 seconds, and then switching the filter cleaning mechanism off again. At the same time, the electronic circuit 40 also sends an output to the display 36 causing it to display filter-cleaning indicia for the period of time that the filter cleaning mechanism is on.
  • the electronic circuit also restarts the suction source 14 once the filter cleaning operation has been completed by the filter cleaning mechanism at the right time to ensure that the suction source 14 is not starting up again whilst the motor 20 of the filter cleaning mechanism is still running down, and then ceases the display of the filter-cleaning indicia on the display 36 as well.
  • the operation of the vacuum cleaner control system ensures that there is no flow of air through the filter assembly 18 when the filter cleaning mechanism is operating. This aids the effective operation of the filter cleaning mechanism, as well as reducing the load that would otherwise be placed on the battery pack 28 by operating the motor 20 for driving the filter cleaning mechanism at the same time as operating the suction source 14 and/or the third motor 26.
