(Cl. 21S-39) 2 Claims.

This invention relates to improvements in electric driers of the type` .involving electrical heating means and an electric fan serving to direct air heated by the heating means against the articles -to be dried within the confines of a hood, the primary object of the invention being to provide a drier of thisv type which is especially, but not exclusively, devised for use in kitchens and the like for rapidly and eiciently drying dishes which have been washed, thereby eliminating laborious towel drying operations and/or relatively long waiting, and less desirable results of..open air-drying of dishes.

; `Anotherrimportant object of the invention is the provision of a device of the type indicated above which -involves:a superior association of electrical heating element, fan, and enclosure therefor. bymeansof .which the production of hot air andfth'e direction'thereof onto the object to be dried are performed more. effectively and emeiently, and thedevice is rendered safe for use under. ordinary conditions of service.

1 A further important object of the invention is to prov-idea simply constructed and rugged deevice .of the'. character indicated above which can `relatively low cost.

. Other important objects and advantageous features off-the invention will be apparent from the following description and the accompanying drawings, wherein, for purposes of illustration onlygfa specic embodiment of the invention is set forth .in detail.` Y j f In the drawings:

Figure 1 is a top plan View;

Figure 2 is a side elevation, with internal parts lshown in dotted lines;

Figure 3 is a vertical longitudinal section, taken onthe line 3--3 of Figure l;

Figure tlis a fragmentary bottom plan view; Figure 5'is an enlarged fragmentary horizontal section taken on the line 5--5 of Figure 2;

and,

Figure 6 is an enlarged fragmentary vertical longitudinal section taken on the line 6--6 of Figure 1.

Referring in detail to the drawings, wherein like numerals designate like parts throughout the several views, the illustrated dish drier comprises a preferably light-weight metal hood l having an elongated rectangular horizontal cross section and truncated pyramidal shape involving the upwardly tapering and mutually convergent end walls 8, 8 the upwardly tapering and mutually convergent side walls 9, 9 and the relatively sha1- low skirt composed of perpendicular end wall portions I0, I0 depending from the lower ends of the end walls 8, 8 and the perpendicular side wall portions II, II depending from the lower ends of the side walls 9, 9.

The upper ends of the end walls il, 8, and side walls 9, 9 are formed to provide a horizontal circular opening I2. A hemispherical hollow dome I3 is formed on or made as a continuation of the upper ends of the end walls and side walls and surmounts the same, the dome I3 serving as a fan motor mounting or support and' as a heat reflector.

On the end walls 8, 8 are provided transversely extending preferably bail handles I4 for handling the device.

Adjustable legs I5 are provided for supporting the device on a surface IB, such as a sink'drainboard or the like, with the under edges of the skirt wall portions I0, I0 and Il, II spaced upwardly from the surface I6 at selected heights, in accordance with the bulk of dishes to be dried. The legs I5 are preferably vertically elongated resilient frames formed of spring wires bent between their ends to provide a lower substantially three-quarter circular loop I1 open at its upper end, one or more intermediate loops I8 open at both ends, and an upper three-quarter circular loop I9 open at its lower end, the upper loop I9 being constituted by the end portions of the wire, and the terminals 20 thereof being in close but unconnected facing relation. The disconnection of the terminals 20 of the legs permits the various loops to be spread so as to clampably accept therein the studs 2| which are secured to proies beyond the outward section of the skirt side wall portions Il, II at points adjacent tothe ends thereof. The studs 2|, as shown in Figure 6, have an irregular, vertically elongated cross section, providing curved sides 22 and upper and lower points 23, 24, respectively, which' consti tute'wedge's. The irregular cross section of the studs 2| provide for non-rotating engagement of the leg loops with studs whereby -the desired vertical positions of the legs are maintainedy and the wedges serve to spread the loops of the legs when sufficient pressure is exerted manually on the legs to transfer the studs into different desired ones of the leg loops for adjusting the height of the hood 1 above the supporting surface I.

The electrical heating element 235 preferably comprises a metal ring 2B fitting the inside of and secured to the dome I3 immediately above its lower end, the ring 26 being provided at equally circumferentiallyspaced intervals with paire of radially rearwardly projecting ears or legs 21 between which are secured, as by rivets 28, radially inwardly projecting preferably ceramic insulators 29 provided with holes 30, through which the heating coil 3| is extended. The ends of the heating coil 3| are secured to an insulator block 32 carried by an extra pair of legs 21 on the ring 26 located between two adjacent pairs of legs 2l. Wires 33 are connected to the ends of the heating coil 3| and are led out through the dome I3v in a suitably insulated conduit 34 having a plug 35 adapted to be plugged into a suitable electric current outlet.

The dome I3 is provided in its upper part above the heating element with circumferentially spaced, relatively small air inlet holes 36"which are sized and arranged to predctermine the proper volume and rate of ilow of air to the heating element 25 to assure proper heating of the-airbefore it is directed onto the dishes within the hood e 1r The-dome I3' isv arranged so that it'act's as:a reflector to reiiect'downwardly the heat radiated from the heating element' and thereby enhance th'eheating capacityof the device, the size and distribution of the air inlet holes 36 being devised so as not to unduly impair the heat reflecting properties ofthe dome I3.

The fan 38 comprises; a relatively small electric motor 39 depending from the top of the dome and secured theretofby suitable brackets 40 fastened' to the motor casing 4|; The lower end 42 ofthe motorcasing is positioned above and at the center of the heating element 25 and is thereby prevented from beingoverheated by the heating coil3laand is in a position to'be cooled by air entering the dome through the holes Sli-and passing' downwardly around the motor casing; Further, this arrangement of the motor does'not interfere with downward reiiection by the lower parto! the dome sides of heat radiated from the heating coil 3|. The shaft 43 of the motor depends below thefheating element 25` andV hassecured thereto on a level close to the underside of the heating element, a relatively large diameter fan bladeV unit 44, which substantially spans the width of the `heating element and that of the opening I2 atthe upper end ofthe hood 1f. A rectangular horizontal protective screen is positioned immediately below the` fan blade unit 44 and is secured toV the hood walls by suitable means indicated at 46;

It will beunderstood' iromftheloregoing that outstanding compactness isnobtained in therelative arrangement of dome, heating element, and fan and that the'arrangement also eliminates all possibility of injurious'contact with thev hands or fingers of a user, and that contact with dishes during a drying operation is eliminated by the screen 45.

It will also appear-from the foregoing that the provision of the relatively large fan blade unit and its spanning and location directlyA in the top opening I2 of the hood 1 produces a relatively uniform iiow ofheated air throughout the in- 4 terior of the hood which effectively reaches all dishes everywhere in the hood and that this assures quick and uniform drying of the dishes or the like over which the hood I is placed. Further, the location of its fan blade unit beneath rather than above the heating element 25 permits uninterrupted and undifiused flow of heated air from the ian downwardly in the hood. At the' same time the air transferrate of the fan and the air :admission rate ofthe holes lieihg properly proportioned, suilicientcontact of the incoming air with the heating coil 3| and with other hood inr spaced relation abovea hoziaontllSuP- porting surface, a domerbridgingthei cpenfupper end of said hood', saidfdome' being` provided? with a plurality oi air intake-holes'andzwithfa rellene tive inner surface, air` in said dome, and electrical" heating means, mounted in said dome. in cooperative: relation" with said air impelling means 2.
