DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to an universal vacuum cleaner, and more specifically to a universal vacuum cleaner in which, the user does not need to disassemble or to exchange parts in the cleaner, to accomplish any one of ordinary dry vacuum cleaning, wet vacuum cleaning of a moist underlay, absorption of water on floors, carpet cleaning, ordinary floor washing and sucking up water from kitchen sinks, toilet sinks or the like. The universal vacuum cleaner uses liquid as a filter wherein liquid with dirt and impurities are separated from the air and the clean air is, free from dust and of a suitable degree of relative humidity, exhausted and the liquid with the dirt accumulated in a liquid container. The container can be emptied, filled up with clean liquid and reinstalled in the vacuum cleaner.
2. Background Art
There is an increasing demand for using liquid detergent on carpets and the like, as users, to a greater extent, have become aware of the health benefits relative, of removing accumulations of dust, bacteria and microorganisms hidden in the carpet pile. Such accumulations are difficult to control by means of ordinary dry vacuum cleaning. Many have shied away from carpeting because of such problems. However, it can be presumed, the amount of dust and dirt that settles, is the same, regardless of whether the floors are covered with carpet or with hard boards. Thus, the use of carpeting, which trap such impurities, would be more acceptable if the user had efficient equipment to remove and neutralize those impurities, for instance through the use of wet vacuum cleaning with liquid, having suitable detergents and disinfectants. Further, by wet-washing the air, before it is exhausted from such a vacuum cleaner, a more healthy and comfortable indoor climate can be achieved.
The known vacuum cleaners can generally be divided in the following main groups: the ordinary dry vacuum cleaners which only are intended for vacuuming water, the type of vacuum cleaners which after disassembly and change over, can be used for both dry and wet vacuum cleaning through the application of liquid on the underlay, and the type of vacuum cleaners, known as carpet cleaners, which are usable for carpet cleaning with shampoo, and, not usable for ordinary dry vacuum cleaning.
In those cleaners that require change-overs, where the user wants to change from dry vacuum cleaning to wet vacuum cleaning or wants to vacuum water, it would require dismantling and changing of parts in the vacuum cleaner. Where waterproof filters are used, they may become clogged entirely if the suction air contains unfavorable mixtures of dirt and water, which form sludge sediments. If the vacuum cleaner is to be used for dry vacuum cleaning, after it has been used for wet vacuum cleaning, it has to be completely dry inside, otherwise the dry dust may cleave to the wet parts inside the vacuum cleaner. These rather troublesome procedures limit the use of wet vacuum cleaning and spot cleaning in a user's daily house cleaning.
Danish patent application no. DK 4838/73 teaches a floor cleaning machine which is claimed to be usable to vacuum dust and liquid. In accordance with the claims of the reference, a cyclone of known design and a blowing motor unit are placed beside each other in order to reduce built-in height of the unit. The blowing motor unit pulls the air through a filter before it is exhausted to the surroundings. The claimed qualities are obtained by using known methods.
German patent no. DE 29 07 395 A1 teaches a suction aggregate including a container containing water as a filter. The container is divided into at least two sections by partitions, after which the sucked air is forced to flow through the water. The suction pressure is provided by an air pump, which is driven by a motor. The motor also dries a turbine wheel, the purpose of which is to free the air withdrawn from the water. The invention does not disclose facilities to pick up foreign matters which are heavier than water (and therefo
