Definitions

  • the invention relates to a nozzle device configured to face a surface to be cleaned and to be moved over the surface during a cleaning action.
  • nozzle devices for various types of vacuum cleaners such as canister vacuum cleaners and stick vacuum cleaners are often equipped with front lights, i.e. lights at a side of the nozzle device which is configured to be at a front position during a cleaning action.
  • Such lights may include one or more LEDs and serve to illuminate an area of the surface to be cleaned in front of the nozzle device during a cleaning action, so that a user of the vacuum cleaner including the nozzle device can easily recognize dirt on the surface area and assess whether or not the surface area is clean.
  • the surface to be cleaned is a floor. Assessing whether or not dirt is present on surface areas at the sides of the nozzle device is more difficult.
  • the invention provides a nozzle device configured to face a surface to be cleaned and to be moved over the surface during a cleaning action, the nozzle device comprising:
  • a nozzle device is equipped with at least one light-emitting source arranged at a side of the nozzle device and configured to emit light from the respective side of the nozzle device. It may particularly be so that the at least one light-emitting source is configured to emit light towards the surface to be cleaned.
  • the side of the nozzle device at which the at least one light-emitting source is arranged may particularly be a side which is configured to be at a front position during a cleaning action or a side which is configured to be at a side position during a cleaning action.
  • the surface to be cleaned is usually a floor.
  • the nozzle device comprises a controlling arrangement for varying at least one parameter of the at least one light-emitting source between a functional value and at least one default value.
  • the parameter varying functionality of the controlling arrangement is related to actual circumstances of a cleaning action, wherein it is intended to set the functional value of the parameter when the side where the at least one light-emitting source is arranged is in the vicinity of an obstacle on the surface to be cleaned. In this way, the nature of the effective light output from the at least one light-emitting source can be varied and particularly be adapted when the side where the at least one light-emitting source is arranged is in the vicinity of an obstacle.
  • obstacle on the surface to be cleaned is to be understood so as to cover any item projecting from the surface, any peripheral delimitation of the surface and any item arranged on the surface.
  • Practical examples of an obstacle include a wall/plinth and a piece of furniture or a part thereof such as a supporting leg.
  • the at least one parameter of the at least one light-emitting source includes power supply to the at least one light-emitting source, wherein the at least one default value of the power supply is lower than the functional value of the power supply.
  • a default value of the power supply is zero and thereby associated with a deactivated state of the at least one light-emitting source. Consequently, it may particularly be so that during use of the nozzle device in a cleaning action, the at least one light-emitting source is not simply operated all the time, but only in situations in which the side of the nozzle device where the at least one light-emitting source is arranged is close to an obstacle on the floor.
  • the nozzle device is particularly suitable to be applied in cordless vacuum cleaners.
  • Plinth cleaning for example, only takes about 5% of the time of a cleaning action, and it is an insight of the invention that the one or more light-emitting sources of a nozzle device do not need to be constantly kept in an activated state, but that it may be sufficient to only illuminate a floor area at a side of the nozzle device when the floor area is a narrow area which is delimited by the nozzle device on the one side thereof and an obstacle on the other side thereof.
  • the one or more light-emitting sources are continuously kept in an activated state during a cleaning action, wherein the one or more light-emitting sources are operated at a lower power level as a default and are only operated at a higher power level when it is useful to do so, i.e. when a side of the nozzle device where at least one light-emitting source is arranged is close to an obstacle. Also in that case power is saved.
  • the nozzle device comprises a coverage arrangement configured to cover the at least one light-emitting source to a variable extent, wherein the at least one parameter of the at least one light-emitting source includes the extent to which the at least one light-emitting source is covered by the coverage arrangement.
  • the nature of the effective light output from the at least one light-emitting source is not (only) controlled through power supply to the at least one light-emitting source, but (also) through extent of coverage of the at least one light-emitting source.
  • the coverage arrangement comprises one of a movably arranged coverage element made of opaque material and a movably arranged coverage element made of colored transparent or semi-transparent material.
  • the amount of light emitted from the nozzle device at the position of the at least one light-emitting source can be varied, whereas in the second case, the color and possibly also the amount of light emitted from the nozzle device at the position of the at least one light-emitting source can be varied.
  • the functional value of the extent to which the at least one light-emitting source is covered by the coverage arrangement is lower than the default value thereof, probably zero so that when a side where at least one light-emitting source is arranged is in the vicinity of an obstacle on the surface to be cleaned, the at least one light-emitting source is freely exposed.
  • the controlling arrangement comprises at least one actuation part which is accessible at the outside of the nozzle device, wherein the controlling arrangement is configured to set the functional value of the parameter when the actuation part is contacted by an obstacle on the surface to be cleaned.
  • the at least one actuation part of the controlling arrangement may be constituted by the optional movably arranged coverage element mentioned in the foregoing, in which case the coverage element is configured to be automatically moved to the appropriate positions when moving in and out of contact with an obstacle.
  • the controlling arrangement includes at least one proximity sensor configured to determine the actual distance through distance detection. Having at least one proximity sensor located at a side of the nozzle device enables automatic recognition of situations in which the side is close to an obstacle.
  • the number of proximity sensors of the controlling arrangement may have any suitable value, and the proximity sensors may be of any suitable type.
  • the at least one proximity sensor is of the type including an output switching circuit, so that whether or not the functional value of the at least one parameter of the at least one light-emitting source is set is dependent on the state of the output switching circuit of the at least one proximity sensor.
  • the at least one proximity sensor is configured to have the output switching circuit in an opened state as a default, and to only have the output switching circuit in a closed state when the actual distance determined by the at least one proximity sensor is equal to or smaller than the reference distance. This allows for having a default situation of interrupting power supply needed for setting the functional value of the at least one parameter of the at least one light-emitting source, and to only enable such power supply when an obstacle is detected at close range.
  • the reference distance may have any suitable value, wherein it is noted that 50 mm is a practical example. In general, the reference distance may be in a range of 0-150 mm or even 0-200 mm.
  • the at least one light-emitting source is arranged at at least one of a side of the nozzle device which is configured to be at a side position during a cleaning action and a side of the nozzle device which is configured to be at a front position during a cleaning action.
  • the nozzle device comprises a side light-emitting source arranged at a side of the nozzle device which is configured to be at a side position during a cleaning action, a side light-emitting source arranged at a side of the nozzle device which is configured to be at an opposite side position during a cleaning action, and a front light-emitting source arranged at a side of the nozzle device which is configured to be at a front position during a cleaning action, wherein the controlling arrangement is configured to vary at least one parameter of at least each of the light-emitting sources in relation to actual circumstances of a cleaning action independently from the others of the light-emitting sources.
  • references to a front or sides of the nozzle device are to be understood so as to be related to an intended direction of (forward) movement of the nozzle device along a surface to be cleaned during use thereof for cleaning the surface. It is practical if the nozzle device has a generally rectangular periphery at a bottom level, but that does not alter the fact that another shape of the periphery is possible as well.
  • the nozzle device is equipped with side light-emitting sources arranged at opposite sides of the nozzle device, it is possible to illuminate areas of the surface to be cleaned which are at the sides of the nozzle device.
  • the nozzle device When, additionally or alternatively, the nozzle device is equipped with a front light-emitting source, it is possible to illuminate an area of the surface to be cleaned which is at the front of the nozzle device.
  • the invention covers an option of varying at least one parameter of the front light-emitting source in relation to actual circumstances of a cleaning action, which does not alter the fact that it may be practical to simply realize effective light output from the front light-emitting source of a predetermined nature throughout a cleaning action.
  • the controlling arrangement of the nozzle device is configured to vary power supply to each one of the side light-emitting sources such that the light-emitting source is only put to an activated state when the side of the nozzle device where the light-emitting source is arranged is close to an obstacle, it is to be expected that during a cleaning action of a floor, both side light-emitting sources will mostly be in the deactivated state.
  • the nozzle device is actually capable of picking up dirt from floor areas at the side of the nozzle device.
  • the nozzle device comprises at least one opening providing access from an exterior to an interior of the nozzle device so as to allow the nozzle device to receive dirt as may be present on the surface to be cleaned near the sides of the nozzle device.
  • the at least one light-emitting source comprises at least one LED.
  • a front light-emitting source comprising four LEDs is normally involved in the design of the nozzle device and two side light-emitting sources each comprising one LED are added to the design, it is found that if the side light-emitting sources would be operated all the time during a cleaning action without any restrictions, this would involve a continuous 50% increase of consumption of power used for illumination compared to a situation in which only the front light-emitting source would continually be operated.
  • the resulting customized use of the side light-emitting sources only involves a 25% increase of consumption of power used for illumination during limited periods of time during a cleaning action, and, in extraordinary cases, possibly also a 50% increase of consumption of power used for illumination during one or more limited periods of time during the cleaning action. Apart from that, there is no increase of consumption of power at all.
  • the nozzle device comprises a battery configured to supply electric energy, wherein the at least one light-emitting source is powered by the battery. It is also possible that the nozzle device is configured to electrically connect to a battery located in a body of a cordless cleaning appliance.
  • the invention is really useful in the field of battery-operated cleaning appliances, which does not alter the fact that energy supply through a battery is not an essential aspect of the invention.
  • the nozzle device may be used as part of a cordless cleaning appliance, but this is not necessary.
  • a battery it is practical of the battery is of the rechargeable type. Further practical options covered by the invention include
  • Figures 1 and 2 relate to a nozzle device 1 according to a first embodiment of the invention.

  • a controlling arrangement 32 which serves for controlling each of the side light-emitting sources 30 in such a way that the side light-emitting source 30 is only activated when the side of the nozzle device 1 at which the side light-emitting source 30 is arranged is close to an obstacle 101 on the floor 100 such as a wall/plinth, and is kept in a deactivated state the rest of the time.
  • the controlling arrangement 32 comprises proximity sensors 33 arranged on the nozzle device 1 at each of the sides of the nozzle device 1, wherein each of the proximity sensors 33 is configured to detect an actual distance d between a reference position on the nozzle device 1, which may be the very position of the proximity sensor 33, and an obstacle 101 as may be present in the vicinity of the respective side, as is the case in the shown embodiment.
  • the respective side light-emitting source 30 is only activated during a period of time that the actual distance d is equal to or smaller than a reference distance.
