Inlet baffle for water heater

Abstract

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.

1. A fluid heating tank comprising:
 a fluid heating tank laying on its side and having an inlet located in an annular sidewall of said tank at a lower portion of said tank and an outlet located at an upper portion of said tank higher than said inlet; and  
 a baffle assembly positioned within said tank over said inlet, said baffle assembly comprising:  
 an inner cap positioned over said inlet including a collar-like base having an inner cover attached to the top portion of said base said inner cover having openings therein to control fluid flow into said tank; and  
 an outer cap attached to and spaced apart from said inner cap by a spacer, said outer cap having a flange depending downwardly therefrom such that water flowing through said inlet may flow through said openings and impinge against a bottom of said outer cap continuing relatively smoothly along the inside of said flange and out into said tank.  
 
     
     
       2. The fluid heating tank of  claim 1  wherein said flange at least partially surrounds said inner cap. 
     
     
       3. The fluid heating tank of  claim 1  wherein said openings and trapezoidal in shape. 
     
     
       4. The fluid heating tank of  claim 1  wherein said outer cap is generally square in shape. 
     
     
       5. The fluid heating tank of  claim 1  wherein said inner cap is generally square in shape. 
     
     
       6. The fluid heating tank of  claim 1  wherein said tank is a water heating booster for use with a commercial warewasher. 
     
     
       7. A fluid heating tank comprising:
 a fluid heating tank laying on its side and having an inlet located in an annular sidewall of said tank at a lower portion of said tank and an outlet located at an upper portion of said tank higher than said inlet; and  
 a baffle assembly positioned within said tank over said inlet, said baffle assembly comprising:  
 an inner cap positioned over said inlet including a collar-like base having an inner cover attached to the top portion of said base, said inner cover having openings therein to control fluid flow into said tank; and  
 an outer cap positioned over said inner cap wherein said outer cap is supported by brackets depending from said sidewall of said tank, said outer cap having a flange depending downwardly therefrom such that water flowing through said inlet may flow through said openings and impinge against a bottom of said outer cap continuing relatively smoothly along the inside of said flange and out into said tank.  
 
     
     
       8. A fluid heating tank comprising:
   a fluid heating tank laying on its side and having an inlet pipe with an end terminating at a lower portion of said tank, an outlet located at an upper portion of said tank higher than said end of said pipe; and        a baffle assembly positioned within said tank over said end of said pipe and adjacent an annular sidewall of said tank, said baffle assembly comprising:      an inner cap positioned over said end of said pipe and including a collar - like base having an inner cover attached to the top portion of said base, said inner cover having openings therein to control fluid flow into said tank; and        an outer cap positioned over and spaced apart from said inner cap, said outer cap having a flange depending downwardly therefrom such that water flowing through said end of said pipe may flow through said openings and impinge against a bottom of said outer cap continuing relatively smoothly along the inside of said flange and out into said tank.        
     
     
       9. The fluid heating tank of  claim 8  wherein said flange at least partially surrounds said inner cap.  
     
     
       10. A fluid heating tank comprising:
   a fluid heating tank laying on its side and having an inlet pipe with an end terminating at a lower portion of said tank, an outlet located at an upper portion of said tank higher than said end of said pipe; and        a baffle assembly positioned within said tank over said end of said pipe, said baffle assembly comprising:      an inner cap positioned over said end of said pipe and including a collar - like base having an inner cover attached to the top portion of said base, said inner cover having openings therein to control fluid flow into said tank; and        an outer cap attached to and spaced apart from said inner cap by a spacer, said outer cap having a flange depending downwardly therefrom such that water flowing through said end of said pipe may flow upward through said openings and impinge against a bottom of said outer cap continuing relatively smoothly downward along the inside of said flange and out into said tank.
