(Cl. 34-19) This invention relates to driers. More particu larly, it relates to a method and means for drying clothes or other material in which there is em ployed an improved electrically heated drying 5 system. One object of my invention is to provide a de vice of the character described, having means for causing a drying medium to flow in a con tinuous circuit whereby the moist clothes or other 10 material in the drier may be quickly and effec tively dried. Another object of my invention is to provide a device of the character described in which a por tion of the drying medium which has absorbed ‘ moisture from the moist clothes or other material in the drier may be quickly exhausted from the drier. A further object of my invention is to provide a drier of the character described comprising few and simple parts, which shall be relatively inex pensive to manufacture, economical to operate and highly e?icient for the purposes described. A still further object of this invention is to l5, suitably positioned within the ducts l2 and I3. Thus it is seen that by the time the air enters the duct H to be deflected into the drying com 10 partment 30 which contains moist clothes to be dried, the said air has been progressively heated by having successively passed over the electrical heater units l5. Said heaters l5 may be of any suitable construction adapted to heat a current 15 of air passing thereover. The cabinet l0 may be of any suitable con struction, the walls 20 thereof being constructed of single or double sheet metal suitably re-en forced, in any well understood manner, and 20 spaced from each other to provide a heat insulat ing air space 2| between in order to retain the drying medium in heated condition in the clothes provide a highly practical method for quickly drying compartment 30. The drying compart and effectively drying clothes or other material which may be easily and economically carried which may be insulated in a manner similar to out. Other objects of this invention will in part be obvious and in part hereinafter pointed out. The invention accordingly consists in the fea tures of construction, combinations of elements, and arrangement of parts which will be exempli ?ed in the construction hereinafter described, and of which the scope of application will be in dicated in the following claims. In the accompanying drawings, in which is shown one of the various possible embodiments of this invention, 40 may consist of one or more units, each compris ing a drying chamber or cabinet 10 provided with a blower ll adapted to force a drying medium, such as air, through a series of spirally connected ducts, I2, I3 and I4 and into a clothes drying is compartment 30, said air being ?rst caused to pass over a plurality of spaced electrical heaters ' Fig. 1 is a perspective view of a drier embodying the features of my invention, the doors being open and certain portions cut away to disclose the in terior construction; Fig. 2 is a sectional view illustrating the con struction of the heating means embodying vari ous features of my invention; Fig. 3 is a plan view, partly sectional, of the portion of my device illustrated in Fig. 2; Fig. 4 is a sectional view taken substantially on the line 4-—4 of Fig. 2; Fig. 5 is a sectional view taken substantially on the line 5—5 of Fig. 4; and Fig. 6 is a sectional view taken substantially on the line 6—6 of Fig. 5. Referring in detail to the drawings, my inven tion is shown as applied to a clothes drier which ment 30 may be provided with close ?tting doors that of the walls of the cabinet III, as described above. A drying rack to accommodate moist clothes or other materials, may be provided in the drying 30 compartment 30 and may comprise a plurality of horizontally spaced members 28, suitably sup ported on cross members 29, said members 29 be ing attached to the walls of the cabinet l0. To permit the heated air in the duct M to be de?ected into the drying compartment 30 the top wall of said duct I4 is provided with a series of adjustable louvres l6 which allow the heated air from the duct M to be de?ected into the drying chamber 30. It is desired that the heated air entering the drying compartment 30 be in constant motion in order that it may more effectively absorb the moisture from the wet clothes. This is accom plished by providing a ventilating device attached to one of the side walls of the cabinet l0 and communicating with the inside of the drying chamber 30. The ventilating device may com prise a ?ue 3i as shown in Figs. 5 and 6 of the drawings, open at the top and bottom to cause a draft of air to pass therethrough in a direction shown by the arrows. It is noted that the top and bottom openings of the ?ue 3| communicate with the air outside of the cabinet “I. Between the inner wall 32 of the ?ue 3| and the inner wall 55 2 . 2,111,148 of the cabinet l0 there is formed an air passage way 33. Said passageway 33 is entirely enclosed with the exception of a plurality of louvres II which may communicate with the drying com~ partment 30, preferably positioned toward the bottom of said compartment, and another set of louvres 36 communicating from the passageway 33 to the ?ue Ii preferably positioned toward the top of the passageway a. 10 A wire screen 40' may be provided to cover the louvres l6;in the top wall of the duct I‘, so that moist clothes which may fall from the drying rack will not clog the louvres I6 to prevent the en trance of the heated air into the drying compart 15 ment 30. The operation of my device may now be de scribed as follows: The moist clothes or similar articles which it is desired to dry are placed on the drying rack with 20 in the compartment 30 and the doors 25 closed. The blower I I is then set in operation. The dry ing medium, which in this case is air from the ' atmosphere within the cabinet, is caused to travel through duct I! in the direction of the arrows 25 (Fig. 2), passing successively over the heaters | 5 to become progressively more heated and dried as it passes over said heaters. The air is then guided into the duct i3 and caused to travel in said duct i3 over another set of electrical heaters 30 I5 to be further heated and dried. The air is then guided by a curved connection into the duct H from which it is de?ected into the drying com partment 30 through a series of adjustable louvres l6 positioned in the top wall of the duct I‘. 35 Since it is seen that the air entering the dry ing compartment is heated and under pressure it will therefore circulate freely through the dry ing compartment 30 in the direction as shown by the arrows in Fig. 1 of the drawings to ab 40 sorb the moisture from the moist clothes there in. It will be noted that the blower II is posi tioned entirely within the cabinet I0 and there fore the air supply entering the intake of the blower ii will come from within the cabinet Ill. 45 As shown in the drawings, the drying compart ment 30 communicates with the intake of the blower ll through an opening 40. Therefore it is seen that a continuous circuit of the drying medium or air is established. The air from the 50 drying compartment 30 is drawn into the blower II and forced through the ducts l2, l3 and I4 and thence into the drying compartment 30 to circulate therein and absorb the moisture from the moist clothes and to ultimately be drawn into 55 the blower intake again' through the passage way 40 to be recirculated. It is seen that after a short period of opera— tion the air entering the blower ll through pas sageway 40 will have already been heated so that 60 each time it is passed through the ducts l2 and I3 containing the electrical heaters IS, the air will emerge from the ducts it in a slightly more heated condition than previously. This process of re-heating the re-circ'ulated air will continue 65 until the air has reached a predetermined tem perature. At the same time that the air is caused to cir culate in a continuous circuit as described above, a portion of the moist air in the drying chamber 70 30 is exhausted to the outside of the cabinet III by means of the ventilating device hereinbefore described. Due to the action of the draft of air passing through the ?ue 3| in the direction of the arrows as shown in Fig. 5 of the drawings, a por 75 tion of the moist air within the drying compart _ ment II will be drawn into the eway II through the louvres I5 and thence into ?ue ll through a set of louvres 36 to be ultimately ex hausted through the top of the flue II. To replenish the air that is exhausted from 5 the cabinet III by means of the ventilating de vice described above, the front wall of the cabi net It may be provided with a grilled or perfo rated portion 45 to allowthe air from the out side to enter the cabinet ll. ' i It will thus be seen that there is provided a method and apparatus in which the several ob jects oi.’ this invention are achieved, and which is well adapted to meet the conditions of prac tical use. _ 15 As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is 20 ,to be interpreted as illustrative and not in a limiting sense.
