Claims.
This invention relates generally to heaters, and particularly to an electric water heater.
The main object of this invention is to construct an electrically operated hot water air warming device which will be relatively small insize and light in weight and which gives off a relatively large supply of heat from a given current consumption within a very short space.
of time after the operation commences.
The second object is to utilize a special form of radiating element for the purpose of extracting the heat from the water which is directly heated by means of an electrical heating element.
These and other objects are accomplished in the manner set forth in the following speciiication as illustrated in the accompanying drawing, in which: I
Fig. 1 is a side elevation of the device.
Fig. 2 is a front elevation thereof. Fig. 3 is a vertical section taken along the line 2-3 in Fig. 4.
4 is a section taken along the line 44 Fig. 2.
5 is a fragmentary side elevation of one of the heat radiating elements with a portion thereof broken away.
Fig. 6 is a transverse section taken along the ine 6-5 in Fig. 5.
Fig. 7 is a diagrammatic view showing the relation of the elements involved in the device.
Similar numerals refer to similar parts throughout the several views.
Referring in detail to the drawing, there is shown a base It upon which is mounted a horizontal tubular boiler ll within which is placed a low heat resistance element l2 and a medium heat resistance element If. The elements l2 and ii are connected to a three-heat switch M to which current is supplied from a line wire i5.
The elements l2 and 13 are connected by the wire ii to a thermostat i'l which floats between the warm contact 18 and the cold" contact ill, the former being connected to motor 20 of thefan 2! by means ofawire22.
The contact I! is connected by means of the wire 23 to the line wire 24 which connects to the second temiinal of the. motor 20.
Extending upwardly from the boiler II are the heat radiating tubes 25 which are preferably of the type provided with a plurality of fins 26. which owing to the manner of manufacture are approximately tangential and .terminate in sharp points 21 from which the heat flows readily.
It will be understood that the resistance elements l2 and it are suitably cased to protect same from the water 28 which is contained within the boiler ii and the tubes 25. Water is supplied to the boiler ii through the pipe 25 from the overhead supply tank III which acts as a safeguard as well as a gauge for if the water boils in the boiler II, it will boil through the auxiliary tank 20 or if the pipe gets plugged by sediment the tank 20 constitutes a safety valve on the top of the radiating element.
The motor 2| and fan 2| are mounted in the casing 3| which is disposed behind the members 25. The case consists of the sides 32, 23 and 34 and the top 25 and encloses the heater down to the base Ill.
If desired, a safety valve 36 is provided at the top of the element 25 which may be connected with a manifold 21, but this is not usually necessary. Shutters may be provided in the front 34 to deflect the air currents in the desired direction.
From the foregoing it will be seen by the use of this construction it is possible to employ a relatively small amount of water in the zone of heat, thereby making it possible to bring the radiator up to a heat delivering temperature in a small amount of time, after which the movement of the thermostat element l'l into engagement with the warm contact II will cause the motor 20 to operate and the air would flow past the fins 26, thereby carrying heat therefrom into the room being heated. The amount of heat being delivered to the boiler ll depends on the heat of the three-heat switch 15, the switch being of the type commonly used on electric ranges whereby a small element l2 provides the low temperature, the large element l3 provides the intermediate temperature and both of the elements provide the high temperature; but whatever amount of heat is delivered to the boiler H, the fan 2i is not operated until the desired boiler temperature is obtained.
Attention is drawn to my former Patent No. 2,151,140 of which this device is an improvement.
I claim:
1. A heater of the class described having in combination a horizontal immersion heater having upwardly extending radiating tubes communicated therewith, said heater containing a minimum amount of water, an elevated storage tank connected with said heater but not in cirdulation therewith, means for circulating air past said radial elementand means for thermostatically controlling the operation of said circulating means in response to temperature conditions.
2. An apparatus described in claim 1 together with means for selectively controlling the flow of heat to said heater.
3. An apparatus described in claim 1 characand an electric storage tank for supplying wate to said boiler but not in circulation therewith.
5. A heater of the class described having combination a base, a horizontal tube mounte on said base, a three-heat immersion heate mounted on said tube, a plurality oi vertic tubes mounted on said horizontal tube in com munication therewith, said vertical tubes hav ing the upper ends thereof closed, an auxiliar water supply tank having a connection on th under side of said horizontal tubes, said ta and tubes being out of circulation, amotor drive fan for carrying the heat from said upright tubes, a thermostat responsive to the temperature of the water in said tubes for controlling the operation of said motor and means for controlling the flow of electrical energy to said heating element.
