Definitions

  • the present invention relates to a slimline air disinfection module suitable particularly but not exclusively, for use within an air disinfection unit.
  • Air disinfection units, apparatuses or systems usually feature relatively sharp corners and edges and includes switches, adjustable feet, handles, control knobs or other parts that protrude from one or more faces. Therefore, they are not suitable to be used or fitted in environments where there is a high risk of abuse or self-harm, for example, in mental health hospitals, patient bedrooms, prisons, and immigration centres.
  • wall-mounted or floor standing air disinfection units are quite bulky and take up a lot of space in the room. They are designed and made using a combination of materials, such as, wood, aluminium or glass, and are easy to dismantle to aid with their maintenance and repair. They are easy targets for tampering and/or vandalism since it is not difficult to take them apart and access the components inside.
  • a slimline air disinfection module providing unimpeded air flow for use within an air disinfection unit, the module comprising: a housing; a module inlet disposed in a front side of the housing; a module outlet disposed in an upper end of the housing; a UV lamp for disinfecting air, an air filter for removing odour and particulates from air and fan means for drawing air into the housing and forcing air out of the housing, the UV lamp, air filter and fan means being disposed within the housing, the fan means having a central axis substantially perpendicular to the front side of the housing; and duct means for ducting air from the fan means towards the module outlet in a direction substantially perpendicular to the central axis of the fan means, the air filter and UV lamp being positioned within the duct means.
  • the module is slimline in a way that it may have a depth of no more than 80 mm.
  • the module may have a depth no more than 60 mm, and more preferably, no more than 50 mm.
  • this provides a slender air disinfection module by allowing air to be drawn in through the front of the module and be released through the top of the module.
  • the module does not take up too much space and thereby can be used and disposed within a slender or slimline air disinfection unit.
  • the module is suitable for use within the air disinfection unit in that it is suitable to be positioned and fixed to the inside of the air disinfection unit.
  • the module is suitable to be incorporated into and/or used within an air disinfection unit such as a bedhead unit (e.g. a medical bedhead unit), a wall-fixed unit (e.g. a wall- fixed decor panel unit) and a bathroom unit.
  • a bedhead unit e.g. a medical bedhead unit
  • a wall-fixed unit e.g. a wall- fixed decor panel unit
  • a bathroom unit e.g. a bathroom unit.
  • One or more modules may be provided within a single air disinfection unit.
  • the module inlet may be a vent or aperture that allows air to enter the housing.
  • the module inlet may be disposed in a lower section of the front side or wall of the housing.
  • the module outlet may be a vent or aperture that allows air to exit the housing.
  • the module outlet may be disposed in an upper wall of the housing.
  • the duct means may have an overall curved extent from bottom to top.
  • a first section of the duct means may extend substantially along a lateral side of the housing and a second section of the duct means may extend from the first section in a direction towards a vertical centre of the housing.
  • the UV lamp and the air filter may be positioned within the first section of the duct means.
  • the fan means may be disposed next to the module inlet. This allows the fan means to draw air straight into the module i.e., the air is drawn into the module through the module inlet and directly through the fan means.
  • air may be drawn into the fan means through a first side of the fan means.
  • the first side may be considered a front side of the fan means.
  • the first side of the fan means may be positioned substantially in line with the module inlet.
  • a central portion or axis of the module inlet may be substantially aligned with the central axis of the fan means. This means that the air enters through the fan means in a direction parallel to the central axis of the fan means.
  • air may be forced out of the fan means through a second side of the fan means in a direction which is at a substantially perpendicular angle to the first side of the fan means. This means that air is forced out through a side of the fan means at an angle to the incoming air i.e., in a direction perpendicular to the central axis of the fan means.
  • the second side may be a side on a circumference of the fan means.
  • the second side of the fan means may be disposed at an upper end of the fan means.
  • the fan means may direct the air towards an upper section of the module.
  • the fan means may direct the air towards the module outlet.
  • the air may flow from the fan means towards the module outlet in a single direction.
  • the fan means may be a centrifugal fan.
  • the duct means may be provided above the fan means, i.e., in the upper section of the module.
  • the UV lamp may extend in a direction substantially perpendicular to the vertical extent of the housing. In other words, the UV lamp may lie horizontally across the module.
  • the UV lamp may be disposed next to the module outlet. This allows cleaned air to be directly released out of the air disinfection module.
  • the UV lamp may be spaced away from the module outlet by a predetermined distance. This reduces the risk of UV light escaping out of the module from the module outlet.
  • the position of the fan means and the position of the UV lamp allow air to be drawn in through the bottom of the module and allow cleaned air to be released through the top of the module.
  • the air filter may be disposed between the UV lamp and the fan means. This allows particulates and odour to be removed from the air that has entered the module before being disinfected by the UV lamp.
  • the air filter may extend in a direction substantially perpendicular to the vertical extent of the housing. In other words, the air filter may horizontally lie across the module.
  • the air filter may be disposed next to the module inlet or module outlet.
  • the UV lamp may be an Ultraviolet-C (UV-C) tube.
  • the UV lamp may be a photo catalytic oxidation (PCO) tube or cell.
  • the air filter may be impregnated with ODOGard (RTM) treatment. This allows airborne smell or odour to be eliminated from the air.
  • RTM ODOGard
  • the air filter may be a high-efficiency particulate absorbing (HEPA) filter, a carbon filter, a polyethylene terephthalate (PET) filter, or a combination of such filters.
  • HEPA high-efficiency particulate absorbing

  • the one or more flanges may be arranged on the exterior of the module housing.
  • the flanges may be spaced around an external periphery of the housing.
  • the flanges may be substantially coplanar.
  • the one or more flanges may be provided to a rear wall of the housing. This allows the module to be secured to a rear wall or member of the air disinfection unit.
  • One or more apertures may be provided in the one or more flanges. This allows fixing means such as bolts, screws or rivets to extend though the one or more flanges for connecting the module to the air disinfection unit.

  • the unit is a modular structure so different sizes of the unit can be provided depending on the size of a room, the desired length and width of the unit by a user, or the number of air disinfection modules required in the unit. This ensures that air can be properly and effectively disinfected within the room.
  • the unit is suitable for fixing onto a wall.ie
  • the unit may in some embodiments be fixed to the wall. However, in other embodiments the unit may not be fixed to a wall.

  • the unit may be provided in areas such as corridors, waiting rooms or ward areas for example, in schools or hospitals.
  • Air can be drawn into the secure enclosure through the front of the unit and be released back into the room through the top of the unit. This allows cleaned or disinfected air to be blown out of the unit without causing substantial disturbance to the user. This also further enables the unit to have a slim design.
  • surfaces within a room can be disinfected to some extent by the cleaned air.
  • the disinfection of air reduces the number of pathogens and particulates in the air and on the surfaces, thereby minimising mould or bacterial growth (for example) developing on the surfaces and reducing the risk of people developing illnesses from inhaling the air.
