Abstract
The invention relates to a domestic water heating system, which comprises: (A) a main water tank; and (B) an accelerator having a sleeve, which in turn comprises a mechanism for flushing lime scale accumulated at the bottom of the internal hollow of the sleeve, said mechanism causes a flow of cold-water from a cold-water inlet, to said bottom of the internal hollow of the sleeve, and from there to the main tank via hollows in the sleeve.
Claims17
A domestic water heating system, comprising:
- a. a main water tank;
- b. an accelerator having a sleeve, which in turn comprises a flushing mechanism for flushing lime scale accumulated at the bottom of an internal hollow of the sleeve, said flushing mechanism causes a flow of cold-water from a cold-water inlet positioned within the accelerator to said bottom of the internal hollow of the sleeve, and from there to the main water tank via hollows in the sleeve;
- and
- c. wherein the flushing mechanism further comprises a sinker connected to a valve which is positioned within said cold-water inlet, said cold-water inlet also having one or more holes at an upper portion of the cold-water inlet;
- and
- d. a cup attached to an upper portion of the sinker;
- wherein when there is no hot water consumption from the main water tank, the sinker and the valve are located at a lower position such that the valve blocks said one or more holes in the cold-water inlet, and when there is hot water consumption from the main water tank, the sinker is located at an upper position such that the valve opens said one or more holes at the cold-water inlet thereby to allow said flow of cold-water which flushes the lime scale.
4 more elements
An accelerator for a domestic water heating system, comprising:
- a. a cold-water tube;
- b. a perforated tube which is attached to a bottom of a water tank, said perforated tube having a top opening, and plurality of holes at a lower portion of its outer wall;
- a cup having a top opening;
- and
- c. a sinker having a cylinder which passes through the cold-water tube, through the top opening of the perforated tube, and through the top opening of the cup, said sinker having a bottom valve and a top stopper along said cylinder;
- wherein, in a stationary state when there is no cold-water flow within the cold-water tube, the bottom valve is located within the cold-water tube, while upon consumption of hot water, a pressure due to a cold-water flow in the cold-water tube elevates the sinker, thereby to raise said cup due to contact with said top stopper, thereby also to open a passage from the interior of the cup into the water tank, and to cause a flow of limescale-flushing cold-water from the cold-water tube and through the perforated tube holes to within the main water tank.
