Definitions

  • the present invention relates to drying apparatus.
  • the invention relates to drying apparatus including a filter unit for removing particulates and bacteria from a waste liquid such as water.
  • JP 11-18999 A The addition of an antibacterial water absorption sheet with a large surface area to encourage evaporation is known from JP 11-18999 A. This counters some of the problems of bacterial infestation and results in less frequent emptying of a water collector. However, particulate matter will be deposited on the sheet, and this will affect the performance of the machine over time and require frequent cleaning.
  • the invention provides drying apparatus comprising an outer case, a portion of the outer case defining a cavity in which articles can be dried, an outlet disposed at the lower end of the cavity and a filter unit arranged downstream of the outlet, wherein the filter unit comprises a particulate filter and a sterilising filter.
  • the sterilising filter is located downstream of the particulate filter.
  • the particulate filter can remove some solid material and larger particulates from the waste liquid to prevent the sterilising filter from clogging.
  • the filter unit further comprises flow directing means for guiding liquid through the filter unit.
  • flow directing means for guiding liquid through the filter unit.
  • the flow directing means allow efficient use of the sterilising filter ensuring that the water leaving the filter unit has been sufficiently treated.
  • FIG. 1 a is a perspective view of a hand dryer according to the present invention.
  • FIG. 1 b is a side view of the hand dryer of FIG. 1 a;
  • FIG. 2 is a section through the hand dryer of FIG. 1 a showing a filter unit

  • FIG. 4 is a perspective view of a liquid treatment module including the filter unit removed from the hand dryer of FIG. 1 a;
  • FIG. 5 a is perspective view from above of the hand dryer of FIG. 1 a showing the liquid treatment module partially removed from the hand dryer;
  • FIG. 5 b is a perspective view from below of the hand dryer of FIG. 1 a showing the liquid treatment module partially removed from the hand dryer.
  • FIGS. 1 a and 1 b show a hand dryer 10 according to the present invention.
  • the hand dryer 10 includes an outer case 12 , a front wall 14 a , a rear wall 14 b , two side walls 14 c , 14 d and a cavity 16 .
  • the rear wall 14 b may include elements suitable for attaching the hand dryer 10 to a wall surface or other suitable fixture. Elements for connecting the hand dryer 10 to a power source may also be included.
  • the cavity 16 is defined by opposing arcuate front and rear walls 16 a , 16 b .
  • the cavity 16 is open at its upper end 18 , and the dimensions of the opening are sufficient to allow a user's hands (not shown) to be inserted easily into the cavity 16 for drying.
  • a high-speed airflow is generated by a motor unit having a fan (not shown). The motor unit and fan are located inside the outer case 12 . The high-speed airflow is expelled through two slot-like openings 20 disposed at the upper end 18 of the cavity 16 to dry the user's hands.
  • a drain channel 22 is located at the lower end 24 of the cavity 16 .
  • the drain channel 22 is delimited by the lower edges of the front wall 16 a and the rear wall 16 b of the cavity 16 and slopes downwardly towards one side of the cavity 16 .
  • An outlet 26 is located in the drain channel 22 .
  • the outlet 26 can take any suitable form. In this embodiment, it comprises a circular aperture with a central plug 26 a .
  • the outlet 26 and plug 26 a delimit a narrow, annular opening.
  • a chamber 40 is formed in a lower part of the outer case 12 below the cavity 16 .
  • the chamber 40 is delimited by a plurality of chamber walls 40 a and has an open lower end.
  • a liquid treatment module 30 is located in the chamber 40 and is held in place by clips, quarter turn fastenings or other fastening means (not shown).
  • the liquid treatment module 30 includes a filter unit 200 .
  • the filter unit 200 is designed to filter particulates and impurities from the water, and to kill bacteria in the water.
  • a filter inlet 202 is located at the upper end of the filter unit 200 and communicates with the outlet 26 .
  • a sump 204 is located downstream of the filter inlet 202 .
  • the sump 204 has a base 204 a .
  • a wall 206 of the sump forms a weir 206 a .
  • the height of the weir 206 a determines the maximum level of liquid that can be contained within the sump 204 .
  • a filter outlet 208 is delimited by the weir 206 a , the wall 206 of the sump 204 and the outer walls 210 of the filter unit 200 .
  • the filter outlet 208 provides an outlet for water flowing over the weir 206 a.
  • a partition 212 extends from the upper portion of the filter unit 200 adjacent the filter inlet 202 into the sump 204 .
  • the partition 212 extends partially into the sump 204 such that the distal end 212 a of the partition 212 is spaced from the base 204 a of the sump 204 .
  • the partition 212 is arranged such that the volume of a first region 204 b of the sump 204 beneath the filter inlet 202 is greater than a second region 204 c of the sump 204 adjacent the weir 206 a.
  • a sterilising filter 214 is located at the base 204 a of the sump 204 .
  • the sterilising filter 214 consists of particles of an iodine-loaded resin.
  • the resin is loaded at a concentration of 500 g/l. In this embodiment, the volume of the sterilising filter 214 is 50 ml.
  • the iodine-loaded resin acts as a sterilising compound to kill any bacteria present in the water.
  • the particles of the sterilising filter 214 are substantially spherical and have dimensions in the range of 0.1 to 2 mm (average particle size 0.8 mm).
  • the sterilising filter 214 is dimensioned such that the distal end 212 a of the partition 212 extends partially into the sterilising filter 214 .
  • a particulate filter 216 is located above the sterilising filter 214 and comprises glass beads with diameters of 4 mm.
  • the particulate filter 216 is located on top of the sterilising filter 214 in the first region 204 b beneath the filter inlet 202 which is bounded by the partition 212 and the sump 204 .
  • the particulate filter 216 has a volume of 10 ml.
  • the particulate filter 216 operates as a pre-filter, preventing larger particles of solid matter (in particular soap) from blocking the sterilising filter 214 .
  • the area of the bed of the particulate filter 216 and sterilising filter 214 is maximised. A large bed area reduces the pressure drop across the filters and increases the resistance of the filters to fouling and becoming blocked.
  • Both the sterilising filter 214 and the particulate filter 216 are located in the sump 204 below the maximum level of liquid that can be contained in the sump 204 . This means that, once the level of liquid in the sump 204 has reached the maximum, operational, level, the sterilising filter 214 and the particulate filter 216 are completely submerged in the water. This is beneficial because the sterilising filter 214 is prone to cracking and forming air pockets if it is permitted to dry out once it has become wetted. By keeping the sterilising filter 214 continuously wetted, this problem is avoided. In addition, this configuration ensures that the water flow is well distributed. Further, the maximum level of liquid should be far enough above particulate filter 216 to allow the head of water to apply pressure on the bed of the filters.
  • the liquid treatment module 30 further includes a liquid dispersion unit 35 located below the filter unit 200 .
  • the liquid dispersion unit 35 is arranged to receive water from the filter outlet 208 .
  • An exhaust conduit 37 located within the liquid dispersion unit 35 provides a communication path from the liquid dispersion unit 35 to the outside of the outer case 12 of the hand dryer 10 .
  • the liquid dispersion unit 35 further includes a collector 100 for collecting water from the filter outlet 208 .
  • the collector 100 has a base 100 a .
  • a high frequency agitator in the form of a piezo-electric device 102 is located at the base 100 a .
  • a fan 104 is supported on one of the chamber walls 40 a .
  • the fan 104 is located outside the chamber 40 separate from the liquid treatment module 30 .
  • the fan 104 is configured to direct an airflow into the collector 100 through an aperture 38 provided in the liquid treatment module 30 .
  • the water removed from a user's hands during the drying process flows down the front wall 16 a and the rear wall 16 b of the cavity 16 and into the drain channel 22 disposed at the lower end 24 of the cavity 16 .
  • the drain channel 22 collects and guides the water towards the outlet 26 .
  • the water Upon entering the outlet 26 , the water passes into the filter unit 200 through the filter inlet 202 (see arrow A). The water falls onto the particulate filter 216 (arrow B) and spreads evenly across the surface of the particulate filter 216 . As the water moves down through the beads of the particulate filter 216 under the influence of gravity, larger particles of dirt and debris will be left behind in the particulate filter 216 . When the water reaches the sterilising filter 214 (arrow C), the majority of the solid particulates in the water will have been removed by the particulate filter 216 .
  • the sterilising filter 214 sterilises the water by deactivating bacteria in the water.
  • the iodine-loaded resin releases iodine into the water at a rate of 1 to 5 parts per million (ppm).
  • Iodine is a strong oxidant and hence acts as broad spectrum antimicrobial.
  • the water flows down through the sterilising filter 214 is sterilised and is then deposited in the bottom of the sump 204 . This process continues and the volume of water collected in the sump 204 increases until it reaches the maximum level permitted by the weir 206 a . Up until this point, the water levels either side of the partition 212 experience an equal force due to atmospheric pressure.
  • the partition 212 directs the flow of water down towards the base 204 a of the sump 204 , down through a part of the sterilising filter 214 located in the first region 204 b of the sump 204 , and back up through another part of the sterilising filter 214 located in the second region 204 c of the sump 204 to the weir 206 a . Therefore, the partition 212 forces the water to follow a convoluted path from the filter inlet 202 to the weir 206 a . In this embodiment, the convoluted path is in the form of a U-shaped path. If the partition 212 were not present, then water entering the sump 204 would tend to flow over the weir 206 a without passing through the sterilising filter 214 , and sterilisation would not take place.
  • FIGS. 5 a and 5 b illustrate the removal of the liquid treatment module 30 from the outer case 12 for maintenance or replacement.
  • the liquid treatment module 30 is removed downwardly from the hand dryer 10 .
  • the filter 200 forms part of the liquid treatment module 30 and is removable from the outer case 12 with the liquid treatment module 30 .
  • the invention could be utilized in other forms of drying apparatus; for example, other forms of domestic or commercial drying apparatus such as washer-dryers, ventilation-type laundry dryers or full-length body dryers.
  • liquid dispersion unit can be used to disperse the collected liquid; for example, an ultrasonic generator, a fan, a heating element or electrolysing apparatus. Any of these devices could be used in place of a piezo-electric device to agitate, evaporate or electrolyse the water (or other liquid) as required.
  • an air bleed or exhaust airflow could be taken from a motor unit.
  • the motor unit for driving the drying process of the hand dryer has a fan. This fan could be used to generate an airflow to vent the evaporated water to the outside of the drying apparatus rather than using an additional fan.
  • particulate filters may be provided. They may be located outside of the sump, for example in the filter inlet to pre-filter water before it reaches the sump.
  • the loading of iodine need not be 500 g/l and may be within a preferred range of 300 g/l to 600 g/l. Further, the concentration of iodine released into the water may also be outside the range of 1 to 5 ppm. What is important is that the concentration is high enough to kill the bacteria in the water whilst low enough to avoid discolouring the water. Further, the volume of the sterilising filter can be varied, provided it is sufficient to sterilise the water.
  • the anti-bacterial agent in the sterilising filter need not be iodine and could include alternative bacteria-killing media; for example, a halogen-containing material or a precursor to a halogen-containing material.
  • a halogen-containing material or a precursor to a halogen-containing material.
  • materials including: Chlorine, Bromine, Iodine, Hypochlorite or Hypobromide.
  • other methods of sterilising bacteria may be implemented; for example, Titanium dioxide or UV-radiation activated silver nanoparticles.
  • the particulate-filtering media and the bacteria-killing media need not form separate stages in the filter and may be combined to form a single unit.
  • the filter need not be removable from the drying apparatus.
  • the filter could remain inside the casing of the drying apparatus when the liquid treatment module is removed.
  • the filter could either be removable separately from the liquid treatment module or be fixed permanently inside the casing of the drying apparatus.
