Benefits of technology
"The present invention provides a method and apparatus for controlling the incoming water flow into a water heating tank. Specifically, a baffle is used to slow down the water flow and minimize turbulence in the tank. The baffle is simple and inexpensive to produce and can be used in commercial warewashing applications. The baffle helps create a consistent temperature gradient in the heated water, improving the efficiency and utility of the water boosters. The baffle can be made from round or square tubing and can be formed or folded from a flat sheet of metal. The technical effects of the invention are improved efficiency and consistent temperature gradient in the heated water."
Problems solved by technology
This high temperature is generally out of the range available from most buildings and houses central hot water source.
In trying to take advantage of this stratified temperature gradient, through some problems have arisen.
Namely, in prior art systems, the incoming water replacing the outgoing “hotter” rinsing water generally enters the tank in a relatively turbulent, uncontrolled manner.
This incoming water disrupts the temperature gradient in the tank thereby detrimentally effecting the temperature consistency of the outgoing water.

Embodiment Construction
[0019]Referring to FIG. 1, the apparatus and method of the present invention is preferably used in a water heating tank, generally designated 10. While a generally annular tank 10 is preferred, the tank may also be other suitable shapes, including saddle shaped, rectangular shaped, etc. The tank 10 preferably includes a water inlet 12 near the bottom of the tank 10, a water outlet 14 near the top of the tank 10 and a heating element 16. A baffle assembly, generally designated 20, is positioned over the water inlet 12 in order to re-direct and slow the flow of water entering the tank 10 so that the turbulence in the tank 10 is minimized. The baffle assembly 20 is preferably of relatively simple construction, is generally inexpensive to produce, and may be used in water boosters of the type used in commercial warewashing applications.
[0020]In a preferred embodiment, as shown best in FIGS. 2-7, the baffle assembly 20 is positioned over the inlet 12 to the water heating tank 10 and cons...

A baffle for slowing the incoming water flow into a booster heating tank so that the turbulence in the water tank is minimized. The baffle consists of an inner cap and outer cap which are positioned over the inlet to a water heating tank. The outer cap is spaced apart from the inner cap such that the incoming water flows through openings in the inner cap and is directed to the underside of the outer cap. The water, having been sufficiently slowed by the contact with the underside of the outer cap, then smoothly flows downward along the outer cap flange and into the main plenum of the tank.
Description
BACKGROUND OF THE INVENTION[0001]This invention relates to liquid heating and storage tanks, and more particularly to a baffle for use in connection with the water inlet for such a heating and storage tank. More particularly, the baffle of the present invention may preferably be used in connection with known water boosters of the type that are used to raise the temperature of water to a desired level for use by a downstream user, generally a commercial warewashing apparatus. The use of the baffle of the present invention with these types of boosters increases the heating efficiency of the booster, thereby lowering energy usage and costs for the user, lowers the time required to heat the water to the desired temperature, and helps to provide water to the downstream user at a consistent temperature.[0002]Warewashing apparatuses, such as conveyor and batch type warewashing or dishwashing machines, generally receive water at a temperature of around 110° from the central hot water supply...
