Embodiment Construction

[0019] Figure 1a A tubular radical oxygen species (ROS) generator 1 according to the invention is shown comprising a UV transparent funnel 2 around which a UV light source 3 is arranged. Preferably, the funnel 2 is made of quartz glass. A dielectric barrier discharge lamp (DBD) is arranged around the funnel 2 , said dielectric barrier discharge lamp (DBD) containing xenon gas in the gas discharge chamber 4 . The xenon excimer emits UV light at 172nm, which is converted to 193nm by the phosphor layer 5, which may comprise NdPO 4 , LiNdF 4 , PrPO 4 , LiPrF 4 、BiPO 4 、LiBiF 4 or a mixture thereof. Figure 1c The details of lamp 3 are shown in . Water 6 from a water supply (not shown) is directed into the funnel 2 and irradiated in the irradiation zone 7, resulting in the formation of reactive oxygen species (ROS) from the water. The irradiated water 8 comprising the ROS is directed out of the generator 1 to eg a washing device.

Abstract

The invention relates to a reactive oxygen species (ROS) generator (32), a washing device (30) and a washing method using such a ROS generator. The reactive oxygen species (ROS) generated by such a generator provide excellent washing power, and degrade organic stains rapidly to environmentally acceptable products. The generator according to the invention consumes less energy for a. comparable washing effect as compared to conventional washing machines.

Description

technical field [0001] The present invention relates to reactive oxygen species (ROS) generators. The invention also relates to a washing appliance comprising such a ROS generator. The present invention also relates to a washing method using such a ROS generator. Background technique [0002] It is desirable to reduce the amount of chemical bleaches such as hypochlorite, oxygen fluoride, chlorine dioxide and chlorine peroxide in detergents. Such agents are expensive to manufacture, are often unstable on storage and may generate environmentally undesirable waste products. An alternative organic pollution removal solution is to use ozone as a bleaching agent. Ozone has the advantage that it degrades into environmentally acceptable products, especially water and oxygen. Ozone is generally generated from air or pure oxygen by means of electrical discharge generators classified as hazardous equipment unsuitable for unskilled operators. Furthermore, discharge generators have ...
