Definitions

  • This invention relates to water heaters and a method of heating water and more particularly to a water heater equipped with an agitator means of unique design which is effective to prevent accumulation of scale and other solid particles in the bottom portion of the water heater.
  • a longstanding problem in the water heater industry is the tendency of dissolved solid particles to precipitate out of the water being heated, which particles will accumulate on the bottom of the tank causing adverse operation and tank failure.
  • Prior constructions directed to this problem are disclosed in U .S. Patent Nos. 4,157,077, 4,263,879 and 4,257,355.
  • Each of said prior art constructions are designed to create a stirring action in the bottom portion of the tank to reduce the tendency of particles to accumulate therein.
  • the principle object of the present invention is to provide a water heater construction which is more effective in reducing adverse accumulations of scale than are the prior art constructions referred to above.
  • a water heater including a water-tight tank and a source of heating water inside the tank.
  • a hot water outlet is located in the top portion of the tank and an agitator assembly is mounted in the bottom portion of the tank.
  • the agitator assembly includes a circular tubular member connected to a source of water under pressure.
  • the circular tubular member has a first row of orifice members mounted around the inner side thereof and a second row of orifice members mounted around the outer side thereof.
  • the orifice members are directed at an angle with respect to a radius line through each of the orifice members.
  • Each of the orifice members includes a flow passageway through which jet-like streams of water are directed into the tank each time water is drawn out of the hot water outlet.
  • the orifice members are all directed in the same direction with respect to the axis of the circular tubular member to produce a swirling action in the bottom portion of the tank, such swirling action being effective to prevent accumulation of solid materials in the bottom portion thereof.
  • the water heater of the present invention is comprised of a tank wall 10, a tank top member 12 and a tank bottom member 14.
  • Top and bottom members 12 and 14 are provided with a plurality of aligned openings 16 and 18, respectively, in which flue tubes 20 are mounted (Fig. 1 does not show a complete set of flue tubes 20).
  • Tank top and bottom members 12 and 14 are sealed to the tank wall 10 and to the flue tubes 20 by any suitable means such as welding to form a liquid tight tank having a water heating chamber 22 therein.
  • a hot water outlet fitting 23 is provided in the top portion of the tank wall 10.
  • the flue tube pattern shown in Fig. 2 is typical.
  • the flue tubes 20 are positioned in an outer row designated by numberal 24 and an inner row designated by reference number 26.
  • the water heater tank is mounted on a support base 28 which houses a burner 30 of conventional construction. Burner 30 is shown schematically in Fig. 1.
  • Circular tubular member 34 is provided with three (3) rows of orifice assemblies 46; i.e., one row on the inner side of the member, a second row on the outer side of the member and a third row on the top of the member.
  • Orifice assemblies 46 are of identical construction and are mounted on member 34 in an identical manner. In the preferred embodiment, orifice assemblies 46 are mounted on member 34 by the following procedure. Referring to Fig. 3, the first step is to form an indentation in the wall of member 34 to provide a substantially flat angled wall portion 48. This can be accomplished by any suitable means such as an hydraulic press. The next step is to punch or drill an opening 50 in wall 48.
  • orifice assembly 46 is comprised of two parts, namely, a mounting clip 52 and an orifice member 54.
  • Clips 52 preferably made of spring steel
  • Orifice members 54 are of cylindrical shape and have a flow passageway 56 therethrough.
  • orifice members 54 are made of an inorganic material such as ceramic and have an external groove 58 in one end thereof adapted for snap engagement with shoulders 60 formed in the end of mounting clips 52. It will be appreciated from the foregoing description that to install an orifice assembly 46 in tubular member 34, a mounting clip 54 is first snapped into opening 50 and then an orifice member 54 is snapped into clip 54 to complete the installation.
  • the row of orifice assemblies 46 on the top of member 32 are positioned so that the axis of each assembly is directed upwardly and at an angle with respect to the verticle. As indicated in Fig. 3 in the preferred embodiment, such angle is approximately 35°.
  • the water in chamber 22 will be heated by the hot gases and products of combustion passing through flue tubes 20 from burner 26 or in the case of an electric heater, the water will be heated by an electric heating element.
  • the agitator assembly means 32 is dimensioned so that the aggregate size of flow passageways 56 in orifice members 54 is less than the size of the flow passageway through inlet tube 36. With such relationship, the velocity of the water flowing through the orifices 56 will be greater than the velocity of water flowing through inlet tube 36 from the source of cold water under pressure.
  • inlet tube 36 is made from 1-1/8 inch O.D. stainless steel tubing and passageways 56 in orifice members 54 have a diameter .2 inches. With such dimensions, the ratio of the total area of the flow passageways 56 in the orifices 56 (total of 21 orifices) will be approximately 84% of the flow area through inlet tube 36.
