Definitions

  • the present disclosure generally relates to the field of bathing accessories. More particularly, the present disclosure relates to an instantaneous non-storage type water heating system with a provision to pressurize the water and to deliver the same through specialized shower heads.
  • a fixed amount of water is always kept inside a chamber (storage tank) which is heated with a heater to achieve a particular temperature.
  • This fixed amount of water (which is normally known as the capacity of the Storage heater) is decided based on the number of the users likely to use the system every day. Normally the temperature to which this water is heated is more than the bathing temperature of the water being used by the user and this is set by a thermostat control, to shut off the heating unit as the temperature reaches this set point.
  • Another essential design parameter here is that the heater is always kept submerged inside the water, to make sure that the heater coil itself does not burn out due to dry heating in Air.
  • a user wants to take bath they add further cold water in this storage tank and the excess flowing out water is used as a shower or filled in a bucket to take bath.
  • the temperature of the mixed water comes down and again prompts the heater to heat the same.
  • the temperature of the mixed water changes - if more water is drawn, then at the start of the withdrawal hot water will come and as more and more water is drawn little colder water will start coming, as the heater cannot heat all the mixed water back to the original temperature immediately.
  • the user has to predetermine the amount of water that he is going to use for completing his bath in advance - normally if he needs one bucket - he would fill two and keep it ready, before starting the bath - as during the bath if he needs more water at the same temperature, he may not be able to draw the same.
  • tank less water heating systems - for shower applications - is when the user wants to temporarily stop the shower during the bath and apply soap or scrub his body. After doing this activity when the unit is started again - it immediately does not give the required hot water - it starts with cold water and then slowly stabilises to give the hot water.
  • this tank less water heating systems may be electrically little more efficient than the conventional storage heaters, but they do not save water usage - the water used for bathing is same.
  • Our invention is here addressing the above grey areas and making the system more efficient.
  • We are having tank-less heating system in which controllable flow of water is passed through a controllable and efficient heating system, apart from this we are adding a Speed controlled Water Pump in the system with which we are able to control the pressure of the water and are delivering the required quantity of heated water.
  • the heated water can be collected into a bucket for a conventional bath as being done with earlier systems or it can be directed through a specially designed shower with selectable and multiple clog free nozzles - a combination of the used nozzles would give the user an umbrella effect, cascading effect, and heavy rain fall droplet effect while using the hot water from the shower head, thus giving him a complete and optimised bathing, with reduced quantity of water used.

  • the inlet control valve 120 acts as the initiator of the process - in the sense that, the entire functions of the unit automatically starts when the user operates the control valve to let in the water inside the unit and switches off automatically as soon as the valve is turned off, apart from the control of the flow rate which is as per the preference of the user to decide the speed at which the output water is required.
  • the termination, with the coupling 120 made of copper or any other suitable synthetic material is connected through an o-shaped washer ring 122 for plugging leakages which is placed before the pressure building centrifugal AC/DC pump 124 to ensure that the water does not leak inside the base unit 154 and create any short circuit in the internal electronics circuit.
  • Another secondary stainless steel (ss) mesh of size 300 to 500 microns 116 is also placed before the AC/DC pump 124 for additional filtration. Either one or both the filter meshes 110 and 116 restricts and eliminates the movement of any particles and dust into the pump and subsequently into the shower ensuring cleaned water delivery for usage by the user.
  • the inlet flow control valve regulates the release rate of water between 0.500 LPM to 4.0 LPM thus leading to incoming water to develop a constraint and in turn increasing the pressure of the water at reduced flow which adds up to the pressure also developed by the pump and this together when passing through the hand shower gives a gushing effect in the form of continuous droplets of size, not limiting to, 450 microns to 3000 microns.
