Claims. 1

This invention relates generally to an electric drier apparatus and more particularly to an improved electric drier having an integral subassembly comprising a unitary casting forming an annular pumping chamber with a peripheral outlet and receiving a heater element removably positioned in the outlet to maximize heat transfer during an air pumping operation. The structure of the present invention further includes a cushioning mounting for the housing member for minimizing and dampening vibration, as well as an improved mounting arrangement whereby the electric drier structure may be conveniently assembled with a base plate connected to a sup porting surface through the means of decoratively concealed connecting screws accessible through openings formed in the bottom of the electric drier casing.

The electric drier mechanism of the present invention further includes an improved timer device by means of which a snap-acting switch action is obtained, together with a cyclic timed operation whereby the electric drier may be operated only during a selected time interval.

It is an object of the present invention, therefore, to provide an electric drier apparatus including simplified structural elements fabricated as readily replaceable subassemblies.

Another object of the present invention is to provide an electric drier structure incorporating improved mounting means for minimizing and dampening vibration.

Yet another object of the present invention is to provide an improved timer mechanism for an electric drier apparatus.

Many other advantages, features and additional objects of the present invention will become manifest to those versed in the art upon making reference to the detailed description which follows and the accompanying sheets of drawings in which a preferred embodiment of an electric drier structure incorporating the principles of our invention is shown by way of illustrative example.

On the drawings:

Figure 1 is a front elevational view of an electric drier according to the present invention;

Figure 2 is a plan elevational view of an electric drier according to the present invention;

Figure 3 is an exploded view showing the elements of a subassembly provided in accordance with the principles of the present invention;

Figure 4 is a cross-sectional view taken substantially on line IVIV of Figure 2;

Figure 5 is a side cross-sectional view with parts shown in elevation and with parts broken away for the sake of clarity of the drier structure shown in Figure 4; and

Figure 6 is a fragmentary broken elevational view of the timer mechanism shown in Figure 5, out illustrating the elements of the timer mechanism in a different relative position.

As shown on the drawings:

An electric drier is indicated generally by the reference numeral it and comprises a dished out cover H having a bottom wall [2 formed with an opening l3 covered by a screen 14 to provide an air inlet into the cover II. The front wall of the cover H is indicated at l6 and is provided with an opening ll surrounded by a retaining ring l8 connected to the front wall It by a plurality of screws It. The retaining ring I8 is provided with an annular recess receiving a lock ring 26. The lock ring 2c, in turn, is seated in an annular recess 2i formed in a generally L- shaped nozzle 22. The nozzle 22 has a flow passage 23 extending therethrough which is counterbored at one end as at 24 to receive a screen 26. Thus, the retainer it, together with the lock ring 20 not only serves to adjustably position the nozzle 22 for relative angular alignment on the front wall l6 of the cover H, but retains the nozzle 22 in abutting assembly with the front wall It so as to keep the screen 26 in closing position relative to the outlet opening ll, thereby to preclude entry of objects into the cover ll through the opening ll.

The side walls of the cover H are indicated at 2i and 28, respectively, and are each provided with an inwardly extending boss 29 and 30 suitably apertured by a threaded opening to accept a correspondingly threaded fastening member.

A base plate 3! is provided and is received by the cover I I. It will be understood that the base plate may be firmly connected to a suitable supporting surface such as a wall, or at any other desirable location where it is desired to position the electric drier [0.

The base plate 35 is provided with a plurality of apertured bosses 32 through which may be extended suitable lag screws or other connecting means for effecting the assembly of the base plate 3! to a supporting surface.

The base plate is further provided with a boss 3% and a boss 35 adjacent the sides thereof and arranged to come in aligned registry with each of the bosses 29 and 3G on the cover ii. Each of the bosses 34 and 35 is provided with a hollow cavity 34a and 35a and apertures are provided in the opposing end wall portions thus formed to loosely receive a connecting screw 35.

Each of the screws 36 is provided with an em larged head portion 36a constructed to cooperate with a suitable adjusting too} and a clip {ii is connected to the body portion of each of the connecting screws 36 for confinement in the hollow cavities 34a and 35a, respectively, thereby to retain the connecting screws 3!; in assembly with the bosses 34 and 35.

It will be noted upon making reference to Figure 4 that the screws 36 are positioned in generally vertical alignment and an access opening 33 is provided in the bottom wall E2 of the cover II in registry with each screw 36 to facilitate manipulation thereof by a suitable adjusting tool such as a screwdriver or the like.

The length of the bosses 3d and 35 and the alignment of the clip 3'1 on each of the screws 36 positions the screws 36 for ready engagement with the threaded apertures provided in the bosses 29 and 3!] as soon as the cover ii is as sembled with the base plate 3|.

Positioned within the cover I i is a subassembly comprising a housing member til forming an annular pumping chamber H and having side walls 42 and 43 each provided with an aperture 42a and 43a, thereby to form an axial inlet means for the pumping chamber 4!.

The housing member All has a peripheral casing portion 4 3 having an opening &6 providing a peripheral outlet for the pumping chamber ii. A second opening i? is provided in the casing portion 44 adjacent the peripheral outlet the opening 41 being surrounded by an upstanding flange 48 and a recess it which receives a flat body portion of a heating element Hit.

The flat body portion Bil carries a skeletal X frame 51 upon which is helically Wound an elec-- trical resistance element 52. The flat body member 58 is inserted into the recess it and one end thereof is resiliently retained by a pair of spring clips 53 connected to the housing member 46 by suitable fasteners 54 while the other end of the flat body member 53 is firmly assembled to the housing member 48 by means of a pair of screws 56 which may be threaded into suitable threaded apertures .57 formed in the walls of the recess i9.

When so positioned, the skeletal frame 521 will extend inwardly into the housing member at so that the electrical resistant element 52 will be positioned in the peripheral outlet formed by the casing portion 44 of the housing member so.

A motor 58 is mounted adjacent the housing member 40 and is provided with a power take-- off shaft 59 which extends through the opening 43a in the side wall 43 to rotatably drive a fan impeller 60. Thus, air will be drawn through the axial inlet means of the housing member 40 and will be expelled over the heating element 52 and through the peripheral outlet 46 formed by the casing portion 44.

In mounting the housing member 4% to the base plate 31 in accordance with the principles of the present invention, a vibration dampening arrangement is provided including a plurality of studs 6| each having threaded portions on opposite ends thereof inserted respectively through a corresponding one of a plurality of apertured bosses 62 formed in the base plate 3! and a corresponding one of a plurality of apertured bosses 63 formed on the housing member 40 and arranged to lie in coplanar relationship.

On the medial portion of each stud 61 is provided a bushing 64 made of an elastic cushioning material such as rubber or the like and which may be actively interposed between the housing member so and the base plate 3| to absorb and minimize any vibration occurring as a result or" the operation of the drier apparatus. A nut Eb may be provided on each end of each stud M to draw the housing member 40 and the back plate 31 into cushioned assembly with one another.

To set the electric drier [ii in operation, an actuating mechanism including a push button 10 connected to a push rod H by a pin i2 is employed to engage a plunger rod l3 forming a part of a timing mechanism.

The push button is supported for reciprocation by a bearing 14 threaded into an aperture it formed in the front wall it of the cover H. The push rod H is further supported for reciprocation by a guide nut Tl threadedly assembled on the bearing 14.

In Figures 4, 5 and 6, the timer mechanism is indicated generally by the reference numeral I01. Said timer mechanism is mounted on a frame 88, the flange I02 of which is secured to the base plate 3| by means of screws N33. The timer mechanism includes a pair of elongated spring contact arms arranged in spaced parallel alignment. Using the plane of reference established on the drawings, a lower spring contact arm 18 is provided having a contact pad "l9 on a medial portion thereof and including an end portion normally seated in an aperture 88 formed in a resilient retainer 8|. An upper spring contact arm 82 having a contact pad 83 on a medial portion thereof in aligned registry with the contact pad it is of a shorter length than the lower spring contact arm 18 and is provided with a curved end portion forming a cam-engaging surface 86.

A double face cam wheel 8%; hea ing a pair of cam surfaces 38a and 361) formed as eccentrically ofiset semicircles is aligned in operative registry relative to the spring arm contacts 13 and $2.

In the position of Figure 5, the lower spring contact arm 18 is retained by the retainer 8! so that the contact pad 19 is spaced away from the contact pad 83, the upper spring contact arm 52 having its curved cam-engaging surface 84 abutting the cam surface 86a.

Upon pressing the push button lB inwardly, the plunger 13 moves to the dotted line position, thereby displacing the retainer 6i and disengaging the end portion of the lower spring contact arm 78 out of the recess 8G, whereupon the spring contact arm 78 will move upwardly so that the contact pads 19 and 83 make electrical contact with one another.

As the cam wheel 86 rotates counterclockwise, the engagement between the cam surface 36a and the canvengaging surface M on the upper spring contact arm 82 will force the spring contact arms 82 and 78 downwardly until the end portion of the lower spring contact arm will again register with the aperture 89. As soon as the push button H3 is released, a control spring 8? surrounding the plunger 13 and bottomed against the frame 88 having a spring seating tab 38 struck therefrom will urge the plunger '53 toward the full line position shown in Figure 5. Thus, when the cam wheel 86 has moved through half a revolution including of arc corresponding to the extent of the cam surface 86a, the contact pads 19 and 83 on the spring contact arms 18 and 82 will'be retained out of electrical engagement.

It will be understood that when the push button. in is again actuated, the same cycle of operation will occur since the cam surface 86b is similar to the cam surface 86a and will keep the contact pads 19 and 83 in electrical contact engagement for a predetermined time interval proportional to the rotational speed of the cam wheel 86.

It may be noted that the spring contact arms are connected to the frame 83 by suitable fastening means indicated at 90 and the retainer 8 1, together with the cam wheel 86 are carried by the frame as in predetermined spaced alignment relative to the spring contact arms 18 and 82 by any suitable means including a pin 9| for the cam wheel 85 and a fastener 92 for the retainer 8!.

In installing the electric drier, the parts to be carried by the base plate 3| are first assembled thereon. The housing 49, with the fan impeller St and the heating element I00 in place, is secured to the base plate by means of the studs M. The motor 53 is likewise fastened to the base plate (by means not shown) and the frame 88 carrying the timing mechanism is secured by screws is passing through the flange 102 into the base plate 3|.

Similarly, before assembling the cover I! on the base plate 3|, the various parts carried by the cover, such as the nozzle 22 and push but ton is, are first positioned in place. A rubber ring Hill is then fitted into an annular recess 2% formed for the purpose in the inner face of the front wall 16 about the opening 11.

The cover is next positioned over the base plate and the screws 36 screwed home into the internally threaded bosses 29 carried by said cover. In so doing the rubber ring, or gasket, I04 is compressed between the cover and the end of the end face of the peripheral opening 46 to seal the joint therebetween and cause all of the air from the pumping chamber to be discharged into the nozzle 22 when the drier is being operated.

Thus, only the two screws 36 serve to assemble the cover I I in place over the base plate SI. This greatly facilitates both assembly and disassembly. Also, the hidden arrangement of the screws makes for a much neater exterior appearance of the drier; since no attaching means are then visible from the outside and the base plate 35 is with its wall attaching lug screws is entirely concealed by the cover.

Although various minor structural modifications might be suggested by those versed in the art to the preferred embodiment herein described by way of illustrative example only, it should be understood that we wish to embrace within the scope of this patent all such modifications as reasonably and properly come within the scope of our contribution to the art.
