Definitions
- F2411 l/00 means on the inner end of the cold water inlet are ar- [58] Field of Search 137/590, 592; ranged so that the jet of water issuing therefrom is di- 350 17 rected tangentially with respect to the vertical axis of the tank to prevent a build-up of sediment on the bot- [56] Reterences Cited tom of the tank.
- This invention relates to storage type gas water heaters.
- sediment is apt to collect on the bottom of the tank, the sediment either entering with the cold water, or being precipitated from the hot water or being due to the electrochemical action of the heating anode.
- the collection of sediment poses yet another disadvantage in that the water in some geographical areas contains a high content of sediment so that when the gas burner ignites, an audible banging sound is heard emanating from the heater due to the water located beneath the sediment becoming overheated and being converted into steam which boils up through the sediment into the cooler water above, where, at this point, the steam bubbles collapse thereby creating the sharp banging sound.
- the present invention relates to a gas water heater including a water tank, a cold water inlet tube leading into said tank and having its inner end located adjacent the bottom of the tank, and means on said inner end for directing the flow of cold water therefrom at least tangentially with respect to the vertical axis of said tank.
- FIG. 1 is a diagrammatic vertical section taken through a prior art type of has water heater and showing the sediment in situ;
- FIG. 2 is a transverse section taken on line 22 of FIG. 1;
- FIGS. 3, 4 and 5 are detail views of alternative embodiments of a dip-tube constructed in accordance with the invention.
- FIG. 6 is a transverse section of a gas water heater showing the invention in situ
- FIGS. 7 10 are diagrammatic views of alternative forms of flue tubes formed integral with the bottom of the tank of the heater.
- FIGS. 11 13 are diagrammatic views of various shapes of tank bottoms and where the flue pipe has been omitted.
- FIGS. 1 and 2 which show a prior art or normal type of gas water heater
- a glass lined water tank 1 is provided, said tank having a vertically extending flue pipe 2 concentrically arranged therein and a bottom 3.
- a gas burner 4 is located beneath the bottom 3 and below the lower end of flue 2.
- a cold water inlet 5 located at the top of the tank serves as the mounting for a downwardly extending dip-tube 6, the lower end of which terminates a predetermined distance from the bottom 3 of the tank 1.
- the top of the tank 1 also serves as the location for a hot water outlet 7 and, as will be seen from FIG. 2, a magnesium anode 8 is suspended from the top of the tank.
- FIG. 3 shows the lower end of the dip-tube 6 curved, as at 11, whereby the flow of cold water will be directed at least tangentially with respect to the vertical axis of the tank.
- the lower end of the dip-tube 6 is provided with a radial constriction 12 so that the tangential flow of cold water will be of greater velocity. More particularly, referring to FIG.
- the lower end of the dip-tube 6 is generally horizontal and includes a constriction designated by the numeral 12' intermediate the horizontal portion of the dip-tube 6, with the extreme end of the dip-tube being an enlarged opening 12" whereby the lower end of the dip-tube 6 defines a venturi for accelerating the flow of cold water issuing from the dip-tube 6.
- the lower end of the dip-tube 6 can be closed and, adjacent said closed end, a circumferential slit or slot 13 provided.
- the invention is not limited to the type of orifices described above and illustrated in FIGS. 3 5 and they may take other forms without departing from the spirit of the invention providing, of course, that the cold water issuing from the dip-tube 6 is directed at least tangentially with respect to the vertical axis of the tank.
- FIG. 6 where, as is indicated by the arrows A, the cold water flows around the flue pipe 2 scouring the sediment from the bottom 3 of the tank 1 and through the drain-cock 10.
- the flue pipe 2 is concentrically arranged within the tank 1, the horizontal plane of said bottom 3 being normal to the vertical axis of the flue pipe.
- the vertical axis of the flue pipe 2 can be arranged so that it is eccentric with respect to the central vertical axis of the tank, the plane of the bottom 3 again being normal to said last-mentioned axis.
- the vertical axis of the flue tube 2 may be concentric with respect to the central vertical axis of the tank and the bottom 3 of the tank angulated with respect to said last-mentioned axis.
- the flue pipe may be concentric with respect to the central vertical axis of the tank and the bottom 3 may be convex adjacent the wall of the tank and concave adjacent to its junction with the bottom of the flue pipe 2.
- the flue pipe may be dispensed with entirely whereupon the bottom 3 of the tank can take any of the forms shown in FIGS. 11 13.
- the bottom 3 of the tank can be planar or it can be convex as is shown in FIG. 12 or it can be convex as shown in FIG. 13.
- a gas water heater including an upstanding cylindrical water tank having a generally vertical central axis and a draincock located adjacent the bottom of said tank, a fixed cold water inlet tube leading into said tank and having its inner end located adjacent the bottom of the tank, said inner end being generally horizontal and shaped to include an intermediate venturi portion leading to an enlarged opening of said inner end, the horizontal inner end being disposed at an angle with respect to said central axis for directing the flow of cold water therefrom tangentially with respect to the vertical central axis of said water tank to thereby prevent a build-up of sediment on the bottom of the tank.
- a gas water heater according to claim 1 including a vertically extending flue pipe within said tank, the plane of the bottom of said tank being normal to the vertical axis of said pipe.
- a gas water heater according to claim 1 including a vertically extending flue pipe within said tank, the plane of the bottom of said tank being angulated with respect to the vertical axis of said pipe.
- a gas water heater according to claim 1 including a vertically extending flue pipe within said tank, the bottom of said tank being convex as it approaches the wall of said tank and being concave as it approaches said flue pipe.
- a gas water heater according to claim 1 wherein the plane of the bottom of the tank is normal to the vertical axis of the latter.
