ApplieationMarch 7, 1947', SerialNo.733,1 `69 zziselaims. (Clisi-.4231) This invention `relates' toodriers, and-more iper# ticularly vto .such driers 'as may be' electrically heated and ventilated ``for-the purpose 'of drying and aeratingarticl'es oflaundry includingbabies diapers.

An object Aof Lthisinvention isft'o provide a. drier in which the dangerfoscorohi'ng' or'rburningth'e' article to,b.e dried `is reduced to ,alminimum A further object lis to,.pr.ovide ay drier in'which the .dried articlel may :.be .aeratedg .A-further Objectis to provide adrierin which the danger ofdiscoloration of thearticlesundergoing the drying lprocess,l l,by corrosion .of the support .on which theyv are. suspended, is reduced to asminimum.

A further object .is Sto provideadrier.inwhich fresh 'air is forced, heated and uniformly circulated substantially throughout the drier and then exhausted to `thea-.outer :atmosphere YA `further .Objectis to .provide .automatic control of the temperature withinthe drier.

A further object is to provide a portable drier of inexpensive, simple construction having a minimum of parts contained .within an enclosing cabinet which may be readilygmoved toianyrsuitable location when desired ior inse, or'.readily stowed when not in use.

The above and still furtherfzobjects ofthis invention, aswell as` its construction, arrangement and operation, will become apparent from the following description when taken in conjunction with the accompanying drawings, the invention being particularly pointed out in the appended claims.

Reference is made to the drawings wherein like numerals of reference apply to the same parts throughout the several views, and wherein:

Figure 1 is a front elevation, partly in section, of the drier,

Figure 2 is a plan view of the drier partly in section,

Figure 3 is a sectional elevation taken along line 3--3 of Figure 1, looking toward the air inlet end of the drier,

Figure 4 is a sectional elevation taken along line 4-4 of Figure 1, looking toward the opposite end of the drier from the air outlet,

Figure 5 is an elevational view of the air inlet end of the drier, and

Figure 6 is a perspective view of an air deector used within the drier.

Referring to the drawings in detail, a portable cabinet comprising a front I0, rear II, ends I2 and I3 and bottom I4, of any suitable material 2 cut `andV bent to desired'shape and welded,riveted orotherwlse' secured together, is provided Vwith a'lid or cover vISadapted for raising'on hinges IG-'a'n'd` 'containinga screened .exhaust port Ia, a'handle I1 and`legs I8, forming' a suitable en closure wherein may be located the various devices 'for supporting articles to vbe dried and aerated 'and theequipment installed to complete the ydrying .and aerating operations.

lNear the top of the cabinet and longitudinally disposed therein 'are a Aplurality of spaced rods I9 of any suitable shape and composed of noncorroding material. These rods are supported by meansof end brackets v2l! which are secured in any suitable manner .to the ends of the cabinet. The articles to be dried or aerated may be `hung or otherwise vsupported from these rods, as showniin Figures 1 and-4, Where articles 2l and 22 of different sizes are indicated.

.A plurality of angular .frame supports 23 secured by means .of`"bolted brackets 25 to the AWalls II) fand all :ofthe cabinet vhave drip pans 26I welde'dor :other-wise l secured :to them. These pans mrefprovided vfor ithe .purpose of catching any excess moisture dripping from the articles to be dried. These drippings maybe discarded infanyifsuitableumanner,'such as, for example,

connecting' y.with "a drainage system. 'The locationlfo'f "the 'theater iunits I21 beneath and pro tected by the drip pans 26 also serve to prevent the drippings from contacting the heater units, and thus being converted into steam to retard the drying process. These drip pans also serve the purpose of shielding the drippings from the main force of the air stream and thus serve to prevent their being re-deposited on the drying articles by the force of the air stream.

Positioned beneath and preferably supported by means of brackets 25 are a plurality of electrical heater units 21 to heat the air within the cabinet.

At one end of and preferably within lthe cabinet an electric-ally driven fan 28 is located adjacent a suitable screened opening or aperture 29 for the purpose of forcing fresh air into the interior, and thus accelerating the drying operation.

Air deflect-.ors 3D, 3|, 32 and 33 are s-upported by means of the frame brackets 25 and are sui-tably proportioned and disposed to assure 1a uniform distribution of the air from fan 28, throughout the interior of the cabinet, until exhausted through screened exhaust .port 15a in the hinged cover.

The air deflectors, shown. in detail in Figure 6,

3i, 32 and 33 may be assembled as a complete unitl prior to installation within the cabinet.

On one end of the cabinet, preferably on the,...l

inside of end i3 where the fan is locate-d, control switches 3l and 38 are installed for separate control of the fan motor 28 and heater uni-t 27, re`

spectively. The manipulating knobs or handles of these switches may extend through the' cabinet wall to the outside for ease of operation. These switches 3! and 33 may also embody a variable control, such as, for example, a rhcostat, in order that various degrees ci heat may be obtained from the heating units 2l and vfor varying the speed of the fan 28, as desired or required. A thermostat S9 may also be secured to therinside of the cabinet end i3. The electrical equipment herein den scribed may be connected and correlated in an electrical system of conventional design for lull automatic control 'to maintain any predetermined condition of heat 'and `air circulation within the cabinet and arranged to prevent charring or burning of the articles inthe event of failure of the fan to properly operate. An extension cord and plug /iii is provided for connection to any suitf able source of electrical power.

It will be understood that in addition .to drying the articles placed within the drier, such ar- .ticles can also be aerated by turning oii the current to the heating units 2l and running the ian 2B at suiciently high speed to cause the dried articles to become soft and fluffy.

It is to be understood that various modications and changes may be made in this invention without departing from the spirit and scope thereof, as set forth in the appended claims.

What is claimed is: y

l. In a drier, an open topped cabinet having side and end walls, a cover hingedly mounted over the open top of said cabinet and havingan open- 4 ing therein, a plurality of spaced, parallel horizontally disposed rods positioned Within said cabinet adjacent the top thereof and supported by the end walls of the cabinet for supporting articles to be dried, a plurality of spaced frame supports disposed below said rods and secured to the side walls of said cabinet, a plurality of pans arranged longitudinally in said cabinet and supported on said frame for collecting water from the articles being dried, heater units `l` disposed below said drip pans and supported in said cabinet, there being an aperture in one of said end walls for the ingress 7 therethrough of air, and a ian positioned contignous lto said aperture for circulating air through said cabinet and out through the opening in said V'side vand end walls, a cover provided with an opening hingedly mounted over the open top of said cabinet, a plurality of spaced parallel horizontally disposed rods positioned within said cabinet adjacent .the top 'thereof and supported by the end walls on the cabinet iorsupporting articles to be dried, Aa plurality of spaced frame supports disposed below said rods and secured to the side walls of said cabinet, a plurality of pans arranged longitudinally in saidv cabinet and supported on said frame supports for collecting water fromthe ar -ticles being dried, heater units disposed below said drip pans and supported in said cabinet, there being an aperture in one of said end Walls for ingress therethrough voi air, afan positioned contiguous to said aperture for circulating said air throughy said cabinet and out through the opening in said cover, and a plurality :of spaced 4air deflectors arranged below said drip pans and dependin-gly supported in said cabinet.
