Abstract
A water heater cold water inlet deflector means which creates turbulent flow within the inlet conduit and creates turbulent water circulation throughout the water storage tank so that sediment is disturbed and suspended, stacking is prevented and efficiency is improved.
Claims14
A water heater comprising a water storage tank;
- a water inlet port;
- and an inlet conduit connected to said port and extending into said tank, said conduit having a passage for water flow;
- deflecting means positioned internally of said conduit and having an angularly arranged surface relative to said conduit for deflecting the path of water flow, said deflecting means being constructed and arranged to create turbulent water flow within said conduit and to introduce turbulent water into said water storage tank.
An inlet tube for a water heater storage tank, adapted to prevent sediment accumulation in said water heater storage tank, said inlet tube comprising:
- (a) a tubular member having a proximal end adapted for mounting to a water heater inlet port and a distal end adapted to be positioned in said tank, said tube having a wall and a water flow passage for introducing water into said tank;
- and
- (b) means forming a plurality of water-deflecting notches in said tubular member extending within said passage and into said passage and wall proximal to said distal end of said tubular member.
In a gas fired water heater having a burner, a combustion chamber, a water storage tank, a cold water inlet conduit, a hot water outlet port, and a flue extending through said stored water, the improvement comprising a turbulating means providing turbulation to circulate the water in the tank to prevent stacking upon repeated energization of said burner and heating of said flue, said turbulating means comprising an angularly arranged surface relative to said cold water inlet conduit and providing turbulation to suspend sediment in said water for removal with water from the hot water outlet port, and said turbulating means providing turbulation in said tank to stir the water in the tank to increase the output capacity of said gas fired water heater.
