Definitions
- the invention relates to conventional vacuum cleaners or electrically or mechanically driven brooms (sweepers) which are combined with ultraviolet lamps and more particularly to UV germicidal lamps having germicidal effect for killing or inactivating bacteria, viruses and other primitive organisms during cleaning and UV black-light lamps having black-light effect for improving visibility of white, luminous, fluorescent particles and substances also during vacuum cleaning.
- UV lamp having germicidal effect or UV germicidal lamps there are two types of ultraviolet lamps, UV lamp having germicidal effect or UV germicidal lamps and UV lamp having black-light effect or UV black-light lamps, which are relevant to the invention disclosed in the present application.
- the UV germicidal lamp is low-pressure mercury vapour discharge lamp with a tubular glass envelope, which emits the short-wave ultraviolet radiation with a peak at 253.7 nm (UV-C) for germicidal action in which killing or inactivating bacteria, viruses and other primitive organisms and therefore the lamp has germicidal or sterilizing or disinfecting effect.
- Lamp glass filters out the 185 nm ozone-forming line. UV-C can burns skin and cause eye injury either from direct or reflected radiation.
- the UV germicidal lamp requires usage of protection goggles, glove, skin protection and eyes protection (ordinary glass) and therefore is not suitable to be used for illumination. It is understood that the UV lamp fixture incorporates an UV lamp and all other electrical and electronic parts, a fixture or armature, a transparent protection cover, reflexive material etc which are needed to the lamp to work and therefore those parts will be omitted from the following text.
- UV lamp which is used for sterilization of micro-organisms, is attached to a handling tube of a vacuum cleaner and therefore that lamp illuminates the surface of floor directly with germicidal radiation and everything around with reflected germicidal radiation from the cleaning surface.
- the UV lamp disclosed in that patent is not suitable to be used for a purpose of improvement of visibility even for sterilization without the protection for eyes and skin.
- UV lamp which is used for sterilization of micro- organisms, is located inside the suction nozzle toward the cleaning surface.
- UV germicidal lamps which are also used inside suction nozzles of vacuum cleaners, are disclosed in patents no: US4907316, US5233723 and GB648967.
- the incorporation of the UV germicidal lamp inside the suction nozzle of the vacuum cleaner increases the height and such suction nozzle can not enter in the narrow space between the floor and the furniture where the conventional suction nozzle can.
- the UV germicidal lamp incorporated inside the suction nozzle can be disconnected or easily damaged and therefore such technical problem could be solved using the UV germicidal lamp which is located in a separate and attachable housing to the conventional suction nozzle, as disclosed in one embodiment of the present invention.
- the UV germicidal lamp incorporated inside the housing can be disconnected or easily damaged and therefore such technical problem could be solved using the UV germicidal lamp mounted to the housing through shock-absorbers.
- UV lamps radiate the cleaning surface through transparent sheets and transparent suction nozzles (operating as any other conventional suction nozzle) and therefore they are not combined with dust containers.
- UV germicidal lamps are used in the housing of the conventional canister and upright vacuum cleaner to "radiate the surface to be cleaned, and dust or like so as to sterilize them".
- the UV germicidal lamp and a dust container having a transparent bottom and a dust container having a transparent suction nozzle are not used in a combination with a protective housing for preventing reflective radiation, a security on/off switch for preventing a risk from radiation in "up" position and a centrifugal dust filter incorporated in the motor-fan, all as parts of the present invention.
- the centrifugal dust filter keeps dust particles with micro-organisms inside the dust container while the conventional vacuum cleaner keeps particles with micro ⁇ organisms in the dust bag or container and in the conventional filter.
- So dust particles with micro-organisms in the dust container of the present invention can be exposed to radiation and sterilisation from the UV germicidal lamp all time while particles with micro-organisms collected in the filter of the conventional vacuum cleaner can not.
- the dust container having the transparent bottom, as the part of an electrically or mechanically driven broom or sweeper is not used in a combination with a UV germicidal lamp.
- the suction nozzle or the housing of the upright vacuum cleaner having UV germicidal lamp has no any protection from reflective radiation from the floor and from a direct radiation if the suction nozzle or the housing is in "up" position or turned toward the person who cleans (or others).
- the L)V germicidal lamp which surrounding the handling tube of a vacuum cleaner, conducts radiation through optical fibres toward the cleaning surface.
- UV-C radiation is not directed toward the handling tube and the UV germicidal lamp doesn't radiate the air which passing through the handling tube.
- that lamp doesn't radiate the cleaning surface and a dust bag through reflected radiation coming through internal side of the connecting parts which internal surface is coated with reflective material, as disclosed in one embodiment of the invention.
- a sterilization chamber with or without a transparent tube is not used in any combination with a UV germicidal lamp and the handling tube of a conventional vacuum cleaner.
- UV germicidal lamp in the invention disclosed in the patent US3975790 is used for a purification of the exhausted air and therefore UV-C radiation can not destroy the rest of micro-organisms left in the dust bag and in the conventional filter of a conventional vacuum cleaner.
- An important part of the vacuum cleaner having the germicidal lamp is an UV black- light lamp with black-light effect which simultaneously with the germicidal lamp contributes in increasing visibility and cleaning efficiency. Those lamps are so linked to form a single general inventive concept which is a requirement of unity of the invention.
- the UV black-light lamp is low-pressure mercury vapour lamp with phosphor coating on the inner surface of the fluorescent tube which absorbs the UV-C emitted by the low pressure mercury arc and emits longer UV wavelengths (UV-A, between 345 to 400 nm) and therefore is used for black-light effect which causing fluorescent particles and substances to glow and white and luminous particles to be seen better.
- UV-A can not burn skin and cause eye injury either from direct or reflected radiation.
- the UV black-light lamp can be used for illumination without protection goggles, glove, skin protection and eye protection.
- UV lamp which is used for sterilization of micro-organisms, is attached to a handling tube of a vacuum cleaner and therefore that lamp illuminates the surface of floor directly with germicidal radiation and everything around with reflected germicidal radiation from the cleaning surface.
- the UV lamp disclosed in that patent is not suitable to be used for a purpose of improvement of visibility without the protection for eyes and skin.
- any UV germicidal lamp does not consist of any fluorescent material
- the UV lamp disclosed in that patent can not provide black-light effect, which causes fluorescent particles and substances to glow or to be visible and white and luminous particles and substances to be better visible and therefore such lamp can not be used for improving visibility of said particles at the cleaning surface during cleaning.
- UV black-light lamps with black-light effect are not used in any combination with the vacuum cleaners or electrically or mechanically driven broom (with or without an UV germicidal lamp) to cause white and luminous particles and substances to be better visible and fluorescent particles and substances to glow and to be better visible or to be visible even if they are not visible under normal light and therefore they are not used for improvement of visibility and ocular detection of such particles and substances during cleaning.
- the suction nozzle of a vacuum cleaner which incorporates an UV germicidal lamp with germicidal effect, strikes often at the furniture and therefore the lamp could be disconnected or easily damaged during cleaning and sterilizing. If the suction nozzle of the vacuum cleaner is lifted or it is not enough protected, the radiation from the UV germicidal lamp can radiate a cleaning person causing damage to eyes and skin.
- technical problems consists of the following questions: How to protect UV germicidal lamp to be damaged during cleaning? How to provide an additional protection from UV-C radiation for the person who cleans? How to radiate accumulated dust in the dust container and the cleaning surface at the same time during cleaning?
- the UV germicidal lamp fixture is located in a protective housing which is attached, as an independent attachment, at the back of the conventional suction nozzle. Moving forward, the conventional suction nozzle strikes at the furniture and therefore it indirectly protects the lamp inside the protective housing to be damaged. In addition to shock-absorbing arms which are located between the protective housing and the conventional suction nozzle amortize strikes.
- the protective housing has an inner compartment, which surrounding the UV germicidal lamp fixture.
- the lamp fixture is attached to the ceiling toward the cleaning surface and therefore the radiation which is reflected from the cleaning surface is directed toward the space between the inner compartment and the protective housing preventing leakage of radiation outside and providing an additional protection.
- An automatic mechanically releasing arm of an on/off switch connected to the UV germicidal lamp fixture disconnects electricity from the lamp fixture when the protective housing is lifted or when a person who cleans releases it by putting away the hand from the handle (which incorporates the releasing arm of the switch) and therefore radiation outside of the protective housing is avoided.
- the UV germicidal lamp fixture which is located inside the electrically or mechanically driven broom or a compact vacuum cleaner, radiates dust in a dust container and through the transparent bottom of the dust container radiates the cleaning surface.
- the UV germicidal lamp fixture which is located inside a sterilization chamber, radiates the air or the air with dust which passing through the sterilization chamber or the transparent handling tube (if it is installed in the chamber).
- the exhausted air which is going out from the vacuum cleaner, contains sterilized viruses and bacteria which are harmless to a person who inhales them during cleaning.
- the sterilization chamber surrounds the UV germicidal lamp fixture and the transparent handling tube (if it is incorporated in the chamber) and provides a protection from radiation.
- the sterilization chamber which has a larger volume in compare with the handling tube, can reduce the speed of the air which passing through the chamber and therefore increase the time of radiation and sterilization of bacteria, viruses and micro-organisms.
- the UV germicidal lamp fixture which is located in the sterilization chamber, can indirectly radiate by reflection the cleaning surface and dust bag if the internal surface of the connecting tubes of the vacuum cleaner are coated with a reflective material. If an ozone type UV germicidal lamp fixture is used inside the sterilization chamber, ozone which is produced by the UV lamp fixture will be spread on the surface in a room by the vacuum cleaner killing bacteria and viruses on the surface.
- an UV black-light lamp fixture having black-light effect is located on the handling tube or broom's stick or suction nozzle from behind so the suction nozzle strikes at the furniture during movement and because of that protects the lamp to be damaged. Shock-absorbing arms absorb shocks of strikes.
- the black-light lamp fixture illuminates the cleaning area behind the suction nozzle causing the rest of white, luminous and fluorescent particles, which are not removed, to glow or to be better visible indicating a need to move the suction nozzle backward for an addition cleaning of that surface.
- the lamps in a combination with a cleaning apparatus can operates on batteries avoiding any connection to mains by a cable.
- the conventional filter system is quickly clogged with dust particles and therefore the suction efficiency is not sufficient and a powerful motor-fan is needed for suction.
- the impeller of axial or radial/centrifugal fan of a vacuum cleaner is provided with a centrifugal dust filter with or without cylindrical filter made of any filtrating material (paper etc).
- the centrifugal dust filter eliminates clogging and therefore a need for very powerful motor-fan /blower with so strong power to overcome resistance of conventional filters during three steps filtration (as usually) and therefore the power or "clean watts" of the smaller motor-blower/fan with the new type of filter can provide the same or similar efficiency of cleaning as the conventional vacuum cleaner.
- the centrifugal dust filter has much less loss of suction and the vacuum cleaner can remove twice as much dust as the popular cylinder cleaners.
- Air stream of smaller motor-fans/blowers of the invention can not spread exhaust air with bacteria, particles of dust etc all around the room as the powerful vacuum cleaners and therefore cleaning with the new vacuum cleaner does not require the surface cleaning due to vacuum cleaning.
- the new centrifugal dust filter with or without cylindrical paper filter when is used in industrial vacuum cleaners or collectors for filtration/separation and collection of airborne particles during grinding, sanding, sawing, sweeping, vacuum cleaning, ventilating and emitting exhausted gases from combustion chambers and combustions engines, eliminates or reduces clogging and therefore a need for a powerful motor-blower with a strong power to overcome resistance of conventional filters (as a subject of clogging) during filtration and therefore the power or "clean watts" of the smaller motor- blower/fan can provide the same or similar efficiency.
- at least two vacuum cleaners are stationary located at different location in the room.
- each vacuum cleaner through centrifugal dust filter sucks in the air with airborne dust particles and micro-organisms contained in the room and therefore prevent that particles fall and to be accumulated on the surface in the room.
- the vacuum cleaner preferably operates all time or non-stop collecting airborne dust particles and micro-organisms. Such vacuum cleaner or "self-operating vacuum cleaner” it doesn't require any man power for operation of cleaning except to empty the dust container from time to time.
- the centrifugal dust filter which is used in a filtration/separation of particles in exhausted gases from any combustion chamber and combustion engine, is provided with a heat-resident grating.
- the centrifugal fan, the dust container and the protective cover of the exhausting chamber are also made from heat-resident material.
- the dust container (27), which is supported by four wheels (30), is covered with an attachable protective housing (31).
- the UV germicidal lamp fixture (14) and the centrifugal fan (53) for sucking in the air are attached to the ceiling of the protective housing (31) toward the dust container (27).
- a handling stick (33) is attached to the protective housing (31).
- a transparent or non-transparent suction nozzle (34) is incorporated in the transparent bottom (28) of the dust container (29), which is transparent for ultraviolet UV-C rays.
- the tubular UV germicidal lamp fixture (14) is located parallel to the long side of the protective housing (31) radiating the cleaning area which is determined by the protective housing (31). The radiation which is reflected from the cleaning surface is directed toward the space between the protective housing (31) and the non-transparent sides (29) of the dust container (27) preventing leakage of radiation outside.
- the radiation from the UV germicidal lamp fixture (14) through the transparent bottom (28) destroys bacteria, viruses and other micro- organisms on the cleaning surface during movement of the vacuum cleaner (26) and inside the dust container (27) all the time during cleaning.
- the dust container (27) is covered with a protective housing (31) having the centrifugal fan (53) for sucking in the air.
