Cleaning and Sterilizing Apparatus Combined with an Ultra-Violet Lamp

Abstract

A cleaning or sterilizing apparatus combined with an UV lamp consisting of an upright compact vacuum cleaner (26) comprising a dust container (27) with a transparent bottom (28) and a suction nozzle (34) incorporated in the bottom (28) and a protective housing (31) which covers the dust container (27) and which incorporates a fan (53) with a centrifugal dust filter (54) and an UV germicidal lamp fixture (14) for destroying micro-organisms on a surface to be cleaned and inside the dust container (27). The dust filter (54), which consists of a cylindrical grating (62) with or without a cylindrical paper filter (63), is mounted to the cylindrical opening (59) of the fan's impeller (53a) and located partly outside of the fan's casing (60) but inside the dust container (27). Rotating at high speed, the fan's impeller (53a) sucks in the air through the dust filter (54), which throws of dust particles outward toward the space inside the dust container (27) preventing clogging, separating particles from the air and obtaining purification of the air.

Description

TECHNICAL FIELD[0001]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.BACKGROUND ART[0002]According to the prior art, 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 killin...

Benefits of technology

[0067]The absorbers (6a) absorb shocks which the suction nozzle (4) makes during striking at furniture during cleaning. The UV black-light lamp fixture (3), which is located parallel to the long side of the suction nozzle (4), is attached from behind the suction nozzle (4). The suction nozzle (4), which is located in the front of the lamp (3), protects the lamp fixture (3) to be damaged when the suction nozzle (4) strikes at the furniture during movement forward. The UV black-light lamp fixture (3) during cleaning illuminates the cleaning area behind the suction nozzle (4) in each movement of the suction nozzle (4) forward causing the rest of white, luminous and fluorescent particles or substances (which are not removed) to glow or to be better visible indicating if any need to move the suction nozzle (4) backward for an addition cleaning. The tubular UV black-light lamp fixture (3) is located toward and parallel to the cleaning surface improving visibility at the cleaning surface along the length of the lamp (3) which is transversal to the direction of movement during cleaning. The UV black-light lamp fixture (3) is located at a height which allows to a person who cleans to see the illuminated surface and to use the handling tube (8) of the vacuum cleaner (1) in a position which is parallel relative to the cleaning surface during cleaning the narrow space between the floor and the furniture.

[0068]In FIGS. 8a-8d (the claim 9) is disclosed another embodiment of the invention in which the tubular UV black-light lamp fixture (3) is attached parallel or transversal to the handling tube (8) of the vacuum cleaner (1) while the compact black-light lamp fixture (9) is attached parallel and longitudinally to the handling tube. The UV black-light lamp fixture (3) is attached from behind the handling tube (8) and therefore located from behind the

Problems solved by technology

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 clea
