Definitions

  • the invention refers to a wasted clean water collector and the safe method that is being carried out by it to collect only pure waste water, placed inside the bathroom sink or kitchen sinks and collects the amounts of clean water escaping when the tap remains open at intervals of use, as for instance is the case during hand washing, shaving, tooth brushing, as well as it collects the significant amounts of clean water that are lost while waiting for hot water.
  • the water needed for use is significantly less than what is consumed overall for the uses.
  • the escaping clean water is mixed with the gray water of use, is degraded and is led to drainage.
  • This wasting clean water which is for a four-person family of 40,000 liters per year, can be collected by the wasted clean water collector and led to water management systems for other uses.
  • the safe method of collecting wasted clean water implemented by the clean water collector enables the user to use a rich natural tap water stream for his uses, leaving the comfort and efficiency to work in his favor, while at the same time maximizing water savings.
  • the user makes a normal use of the tap water without being obliged, in order to save water, to resort to inefficient water uses with smaller amounts of water or to be obliged to change his habits of water use, which is practically difficult to do.
  • the device’s design aims to: (a) allow clean water to pass through the device as long as it flows freely from the tap and drive it away from the area of the sink in order to be collected; and (b) discharge into the bathroom sink drain or the kitchen sink drain the gray water falling on the appliance when use of the water running from the tap is taking place.
  • phase (a) it is necessary in phase (a) the water to flow rapidly through the water flow regulator (1) to the pipes (2) (3) (5) and to quickly fill the tank (7) through the tube (8).
  • the water in the pipes (2) (3) (5) should quickly return and discard the gray water, that falls at the moment, with the overflow created by the overflow lip (4).
  • the device is portable and is placed inside the bathroom sink or kitchen sinks.
  • the head of the device is located below the tap connected to the tube (3) that reaches the edge of the bathroom sink or kitchen sinks and is connected to pipe (5) exiting the edges of the bathroom sink or kitchen sinks.
  • a vital problem is the continuous water flow created by the pipes (2) (3) (5) and the length of pipe (5) which cannot be the same for all bathroom sinks or kitchen sinks because they have different dimensions. Also, the consumer cannot adjust the length each time with accuracy. Even if the consumer succeeds the result will be average. This creates problems of safe operation and reduced performance of the device as shown in the following cases:
  • the bathroom sink or kitchen sink has a low height and the lower end of the pipe (5) is lower than the overflow edge (4).
  • This arrangement creates two serious problems: a) When the tap water flows freely the weight of the water in the pipe (5) creates suction so that all the water in the pipes (2) (3) (5) is sucked in and cannot return to overflow edge (4) when using the water running from the tap. Also, the tank (7) does not fill due to lack of pressure in the tube (8) because all the water in the pipes (2) (3) (5) coming out of the pipe end (5) is sucked in and thus no pressure is created on the pipes (2) (3). b) when use the tap water takes place, a part of the gray water falling into the device whilst e.g.
  • the bathroom sink or kitchen sink is high and the lower end of the pipe (5) is higher than the overflow edge (4).
  • the pressure in the pipe (8), the filling of the tank (7) and the return of the water for overflow from the edge (4), when using tap water, will be at satisfactory levels but the performance of the device will be very small with a large loss of water flow from the overflow edge (4) because of the difficulty the water is facing when it is leaving the bathroom sink or kitchen sink.
  • the bathroom sink or kitchen sink has such a height that the lower end of the pipe (5) is at the same level as the overflow lip (4), thus allowing the tank (7) to fill slowly and permit the return of the water with a slow speed in the pipes (2) (3) (5) for overflow from the lip (4) when using the water running from the tap.
  • factors such as the flow rate of the water or if the tap water column is compact or sparkling, can affect the result.
  • there might be situations such as shaking of water column in pipes (2) (3) (5) following either to be sucked from pipe 5 or return to overflow from lip 4 when the user uses running water from the tap.
  • An important safety feature of the device is the ability to quickly and for a long-time overflow water from the lip (4) when the tank (7) is emptied in order to ensure that the gray water falling on the device during use tap water, is removed even if the use lasts a long time.
  • the volume of the tank (7) is small and its design is such that it collects the largest amount of water having the smallest dynamic energy at the bottom of its useful volume and the smallest amount of water having more dynamic energy, at the top.
  • the only possibility offered by the concentrated water of the tank (7) is to be able to supplement only the missing water from the siphon created in the pipe (2) and in part of the pipe (3) which has been drifted due to water velocity coming back from pipes (5) and (3), when using the tap water, as mentioned in Patent W00003098.
  • the time period from the end of , the overflow caused by returning water from the pipes (5) (3) (2), when using the tap water, until the end of usage is left without overflowing from the lip (4).
  • the grey water that is falling on the clean water siphon created by pipe (2) and part by pipe (3) is mixed with the clean collected water.
  • the inlet and outlet of the water in the tank (7) takes place through the pipe (8) which has a small diameter equal to the diameter of the hole present in the pipe (2) from which the tank (7) is filled and emptied.
  • the pipe (8) ends at the base of the tank (7) in a hole of the same diameter. Due to this design, there are a) friction losses and therefore delay times in water transfer to and from the tank (7), (b) in the case of non-horizontal positioning of the device, the tank (7) cannot be completely emptied because the water remaining after draining 70% of the water therein, it is concentrated on one side of the tank base (7) and cannot be drained due to the small diameter of the hole located at the bottom of the tank (7) at which the upper end of the tube (8) ends.
  • the overflow lip (4) and the bottom of the water flow regulator (1) are at a short distance, facing each other and ending on two surfaces that are parallel to one another.
  • This design allows the formation of a cylindrical surface water film between the overflow edge (4) and the lower end of the water flow regulator (1). That happens during the return and for a smalltime frame after the return of the water from pipes (5) (3) (2) when we use running water from the tap. As a result, small amounts of dirty water are entering to the clean water circuit through pipe (2) because during that time frames the overflow from lip (4) is not sufficient. Also, the runoff surface of dirty water in which lip (4) ends, is horizontal without slop.
  • tank (7) When tank (7) is filled during the free flow of water from the tap and the gray water falls into the device, the following should happen: after the water returns from the pipes (5) (3) (2) to overflow from the lip (4), when the tap water is used, the tank (7) should start to empty. This is not usually happening because after the water entering from tube (8) into the tank (7) is stopped and the overflow from the pipe (9) is stopped, which overflow happens on a continuous free tap water flow, a film of water is created inside pipe (9) due to capillary effect. This happens even if the diameter of the pipe (9) is big enough, of course within the limited margins of the given space. This prevents air from entering the tank (7) in order to be emptied. Also, there is not a sufficient height difference between the tank (7) and the overflow edge (4), in order to allow sufficient suction to disrupt the water film to allow air to enter the tank (7) to empty. The result is that the emptying of the tank is not 100% guaranteed.
  • a water flow switch which: a) Cuts off the water in the pipes who extract the clean water when tap water is being used, introducing in that way the advantage of the safe operation of the device regarding the collection of only clean water, independently of the bathroom or kitchen sinks dimensions, b) Creates a steady and capable pressure on the pipe which fills the safety tank, introducing the advantage of the quick fill up of the safety tank, c) It helps the water flow in the pipe connecting the device with the water flow switch tank, thus introducing the advantage of increasing the performance level of the device.
  • a safety water tank of large volume with big dimensions on the upper part introducing the advantage of draining quickly and safely the dirty water even if the usage of the device takes a long time.
  • a water flow splitter introducing the advantage of ensuring low friction losses in the flow of water, from and to the safety tank, and also better usage of the remaining water in the safety tank, during its emptying stage when the device is not horizontal.
  • a water flow regulator which in cooperation with the water entrance of the shell of the safety tank: a) They don’t allow the creation of water film in air inlet points of the safety tank, introducing thus the advantage of safe respiration, b) They, create a light vacuum in the safety tank introducing thus the advantage of easier filling, c) They don’t allow the entrance of dirty water in the safety tank during the tap water usage.
