Household appliance

Household appliance,

• the household appliance comprising:
• a washing chamber for washing of items to be cleaned;
• a water system configured to feed water to and from the washing chamber for cleaning and/or rinsing of the items therein;
• wherein the water system comprises a UV-treatment chamber for disinfection and/or sterilization of water to be fed to the washing chamber during operation of the household appliance,
• wherein the UV-treatment chamber is provided with a first UV-light source arranged to direct UV-light towards water present in the UV-treatment chamber,
• characterized in
• that the UV-treatment chamber is provided with a first UV-light reflector
• wherein the first UV-light source is arranged to direct UV-light towards the first UV-light reflector, wherein the first UV-light source and the first UV-light reflector are arranged in relation to each other so that, when UV-light is emitted from the first UV-light source and water is present in the UV-treatment chamber, the UV-light from the first UV-light source passes through the water in the UV-treatment chamber before striking the first UV-light reflector, and wherein the first UV-light reflector is arranged so that the UV-light from the first UV-light source striking the first UV-light reflector is reflected into the water present in the UV-treatment chamber
• wherein the first UV-light source is arranged in association with a first opening in a wall of the UV-treatment chamber, wherein the first opening is provided with a first sealed cover that at least partly is made of a UV-transparent material and that has an inner side facing the UV-treatment chamber and an outer side facing away from the UV-treatment chamber, wherein at least a part of the first sealed cover exhibits a UV-transparent zone, and
• wherein the first UV-light source is arranged on an outside of the first sealed cover and directed towards the UV-treatment chamber so as to direct the UV-light through the UV-transparent zone and into the UV-treatment chamber
• wherein the first UV-light reflector is arranged in association with a second opening in a wall of the UV-treatment chamber, wherein the second opening is provided with a second sealed cover and
• wherein the UV-treatment chamber is provided with a second UV-light reflector in addition to the first UV-light reflector, wherein the second UV-light reflector is arranged in association with the first UV-light source at the first opening, and wherein the second UV-light reflector is arranged on the outside or an inside of the UV-transparent material of the first sealed cover around or at a side of the UV-transparent zone so as to, while still allowing UV-light from the first UV-light source to pass through the UV-transparent zone and into the UV-treatment chamber, allow UV-light directed towards the first opening to be reflected back into the UV-treatment chamber.
