ABSTRACT OF THE DISCLOSURE
A thermostatically and timer operated boiler provides steam to a condenser coil partially or wholly submerged in cooling water agitated by a small agitator.
cooling fan blows air at ambient temperature upon the surface of the cooling water thus assisting in removing heat from the cooling water. The air after having passed over the surface of the water is expelled back to atmos-phere. The cooling water is connected to the boiler which is supplied from the cooling water container.

Description
BACKGROUND OF THE I~VE~TIOl~
This invention relates to new and useful impro-vements in water distillation units.
The majority of commercial water distillation units utilize a radiator coil which is cooled by airO
However, these are not efficient inasmuch as it is often ound that steam flows from the condenser together with distilled water.
SUMMARY OF THE INVENTIO~
~ The present invention overcomes these disadvan-tages by providing a water distillatio~ unit, one aspect ~ 1 - .~.
, 1~39V~
of which comprises in combination a water boiler, a source o heat or said boiler, a condenser unit, a cooling water enclosure for said condenser unit adapted to contain cool-ing water at least partially surrounding said condenser unit, means operatively connecting the boiler to the con-denser unit whereby steam is conveyed from said boiler to said condenser unit and ~an means in said enclosure above the cooling water therein adapted to draw air rom the surrounding atmosphere and blow same across the surface of the cooling water in said enclosure and expel the air back to atmospherev Another object o the invention is to provide a device of the character herewithin described which is sim-ple in construction, economical in manufacture and other-wise well suited to the purpose for which it is designed~
With the foregoing objects in view, and othersuch objects and advantages as will become apparent to those skilled in the art to which this invention relates as this specification proceeds, my invention consists essentially in the arrangement and construction of parts all as hereinafter more particularly described, reference being had to the accompanying drawings in which:-~9~t32 DESCRIPTI0~ 0~ THE DR~WINGS
Figure 1 is an isometric view of on~ embodimentof the device.
Figure 2 is a cross sectional view of the device partially schematic for clarityO
Figure 3 is a schematic ViQW o the wiring con-nections for the boiler and fan.
In the drawings like characters of reference indicate corresponding parts in the different figures.
10 DETAII-ED DESCRIPTIC~
The principle of the invention consists of placing a condenser unit in an open container of water or other coolant which then is cooled by a fan which is directed at the water surface.
In effect, the heat from the condenser is trans-mitted to the water in the cooling vessel by direct con-tact of the condenserO The cooling water then having absorbed the heat o condensation, begins to evaporate to the surrounding atmosphere and the action of the cool-ing fan facilitates a more rapid evaporation of the cool~
~g~z~3~
ing water thus giving a more efficient cooling action by conduction and convection of the cooling water than by the direct cooling by air of the conventional radiator coil. This is because water has a higher capacity for heat absorption and transer than airO
The fan is then removing the water vapor produ-ced by the steam condensing rather than just air cooling the condenser which is less efficient.
Proceeding therefore to describe the invention in detail, reference should irst be made to ~igure 1 in which the device is within an enclosure collectively de-signated 10 supported upon legs 11. The front portion 12 of the enclosure contains the boiler 13 and the rear por-tion of the container includes the condenser unit collec-1~ tively designated 14.
A superstructure 15 mounted upon the rear portionof the enclosure, includes air intake grills 16 and air exit grills 17 therebelow supported within general frame-work illustrated by reference character 18.
20Figure 2 shows details of construction in which the boiler 13, manufactured by conventional means, is si-tuated within the enclosure 10 and may be secured within the upper panel of the forward portion of the enclosure by means of fasteners 19 so that it can be removed if necessaryO
An electrical heater unit 20 is situated adja-cent the base 21 of the boiler controlled by a conven-tional timer switch 22 situated on a control panel 24 and the exterior portion of the timer is shown in Figure 1, An electrical conductor 25 is connected to a source of electrical power (not illustrated) and is wired to the timer and the heater 20 as clearly illustrated in Figure 3.
It is preferable that a power take-off plug 26 be provided, the purpose for which will be hereinafter described~
The rear portion 10 of the enclosure is separa-ted from the boiler by means of a partition 27 thus form-ing a cooling water enclosure 28 within which the conden-ser unit 14 is situated~
In this particular embodiment, the condenser unit consists of a coil 29 situated vertically within the container and having a distilled water discharge end 30 at the lower end thereof extending through the wall of the enclosure as clearly shown.
The upper end of the coil is connected by means o a conduit 31, to the upper side of the ~oiler 13 so that steam generated by the boiler, passes through con-duit 31 and to the upper end o the condenser coil where-upon it travels downwardly through the coil being conden-sed into water ~or discharge at the lower end 30.
The condensing action is caused by the fact that : the major portion of the coil within the enclosure 28, is surrounded by cooling water or other fluid at a level in-dicated by reference character 32, This level is main-tained by a conventional float assembly 33 controlling a cold water inlet 34 axtending through the wall of the en-closure.
: The water for the boiler 13 is provided from the cooling water within the enclosure, by means of a U-tube conduit connection 35 extending from the base of the en-closure to the base of the boiler and it will be noted that the water level 32 is situated below the steam exit of the conduit 31.
An electric motor 36 is secured within the superstructure 15 of the enclosure and includes a shaft 37 extending vertically downwardly therefrom, Power for the electric motor may be obtained by a cord and plug (not illustrated) engageable with the electrical power take-of 26 illustrated in Figure 3.
A relatively heavy-duty fan 38 is secured to the shat 37 adjacent the elect~.ic motor 36 and is adap-ted to rotate within the upper coils of the condenser unit 14. This an draws air inwardly through the air inlet grid 16 and blows it upon the surface o~ the water with~
in the condenser coils whereupon it expels through the air exit grid 17 as clearly shown in Figure 2 by means of the direction arrows.
An agitator 39 is secured to the lower end o the shaft 37 adjacent the base of the enclosure also within the condenser ~il to agitate the cooling water and assist in the transfer of heat from the condenser coils to the waterO
The relatively heavy-duty an 38, when in opera-tion, normally forms a watar funnel in conjunction with ~ o~z the agitator 39, indicated schematically by the dotted lines 40 in Figure ~ thus giving a greater surface area or the air to evaporate water rom the cooling water containerO
It will also be appreciated that a conventional thermostat (not illustrated~ should be provided within the electrical circuitry for sa~ety reasons.
In operation, the cold water connection is ac-tivated thus allowing the water level in the boiler and enclosure to rise to the predetermined le~el 32 whereupon the float 33 cuts off the cold water supply, The timer is actuated in order to operate the heater 20 for a predetermined time and this heater boils water within the boiler or steam generator 13 with the steam passing to the upper end o~ the condenser coil and then downwardly through the coil to be discharged as dis-tilled water at the discharge end 30. The condensing ac-tion is due to the cooling water surrounding the condenser coils together with the evaporative action of the fan upon the sur~ace of this cooling water and the mixing of this cooling water is assisted by the agitator 39, ~9~B2 The line 31 from the boiler to the coil should be of sufficient diameter to prevent any back pressure from occurring and to ensure that the steam flow is unimpeded.
I also have found it advantageous to provide a one -~ 5 way valve in the form of a ball and seat asse~bly 41 in the conduit 35 also to prevent back flow or back pressure. The direct connection to the boiler via conduit 35 also provides preheating water to the boiler and eliminates nearly all of the gases out of the water before it enters the boiler.
~0 Since various modifications can be made in my inven-tion as hereinabove described, and many apparently widely ; different embodiments of same made within the spirit and scope of the claims without departing from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
