FABRIC CONDITIONER FOR CLOTHES DRYER Filed Feb. 12, 1964 5 Sheets-Sheet 5 INVENTOR M65112! 6 .ZZQflQWJZZO United States Patent "ice 3,267,701 FABRIC CONDITIONER FOR CLOTHES DRYER Vincent C. Mandarino, St. Joseph, Mich., assignor to Whirlpool Corporation, BentonHar-bor, Mich, a corporation of Delaware Filed Feb. 12, 1964, Ser. No. 344,490 22 Claims. (CI. 6812) The present invention relates to improvements in home appliances and is more particularly concerned with a novel clothes drier and fabric conditioner wherein a dual purpose nebulizer is removably mounted in the access door of the drier for use as a combined part of the machine and can be separated and used as a separate article of utility apart from the drier.

In clothes driers it is desirable to add different types of liquid additives such as bleach, clothes fresheners, waterproofing materials, mildew preventative, mothproofing, fireproofing, fabric softeners, etc. during the drying cycle. In a horizontal drum type of domestic clothes drier, a desirable location for the additive dispenser is on the access door, generally located at the front of the machine. As herefore proposed, such additive dispensers have been single utility, permanently built-in devices which have presented various servicing problems, awkward and bulky structures, and have required undue space thus limiting design efliciency and compactness. Furthermore, prior devices have not been adapted for use apart from the drier.

Accordingly, it is an important object of the present invention to provide a new and improved clothes drier or similar .fabric conditioning apparatus and nebulizer wherein the nebulizer is useable separate and apart from the conditioner, thus substantially extending the utility of the nebulizer.

Another object of the invention is to provide a novel additive dispenser for clothing conditioner access doors.

A further object of the invention is to provide a novel removable door mounted additive dispenser nebulizer for clothes driers and the like.

Still another object of the invention is to provide a new and improved nebulizer construction.

A yet further object of the invention is to provide a novel self-contained nebulizer unit that can be produced and sold at low cost, which is easy to handle, has multiple utility, is simple in structure and easy to clean and service and which can be readily made from relatively unbreakable materials.

Yet another object of the invention is to provide a nebulizer construction which is highly efficient and economical in operation.

Other objects, features and advantages of the present invention will be readily apparent from the following detailed description of certain preferred embodiments thereof, taken in conjunction with the accompanying drawings, in which:

FIGURE 9 is an operating sequence diagram.

In a representative construction, a nebulizer 10 (FIG. 1) is constructed and arranged to be rernovably mounted operatively on the inner side of an access door 11 which is hingedly mounted on the front of the cabinetrof a clothes drier 12. Within the cabinet is a rotary tumbling drying drum 13 defining a treatment chamber compartment having a forward access opening and mounted in any usual or preferred manner to be driven rotatably by suitable power means such as an electric motor and suitable electrical control circuitry such as will be described more fully hereinafter. When the door 11 is closed, the nebulizer 10 is positioned with respect to the .forward access opening into the rotatable druim 13 to discharge a spray of any suitable and preferred liquid material in substantially nebulized condition into the interior of the rotatable drum 13 for conditioning clothing or other fabric material in the load to be treated in the drum.

In the exemplary embodiment of the invention, rotation of the drum 13 is in a counterclockwise direction. The load of material to be treated is carried on the inner surface of the drum 13 until it reaches approximately the 1 oclock position and then falls away from such surface in a generally dispersed manner, landing in substantially the lower left quadrant of the drum chamber. In order to obtain most eifective treating contact of the nebulized material with the load, the nebulizer 10 is oriented to project the spray therefrom slightly to the left of center of the opening generally toward said lower left quadrant for contacting the dispersed load material.

As best seen in FIGURES 5 and 6, the door 11 comprises a generally pan-shaped outer panel 14 and a complementary opposed inner panel 15 with the marginal edges of the panels telescopically secured in known manner. Within the circular groove 17 inset in the inner panel 15 is a sealing ring gasket 18 which engages against the front panel of the drier cabinet in the closed position of the door. In the area outlined by the gasket seating groove 17 is provided an inwardly offset projecting area portion 19 on the panel 15 provided with a generally central, flanged receptacle cavity socket 20 preferably generally complementary in outline to the nebulizer unit 10 and supportingly receptive of the unit for proper operating orientation. This inwardly projecting, nebulizer supporting area portion 19 of the inner door panel is adapted to project into the access opening in the front wall of the drier casing and toward the inside of the drier drum 13 and etficiently positions the nebulizer 10 for dispensing of nebulized treating material into the chamber of the drum 13.

Referring now to FIGURES 2 and 3, the nebulizer 10 comprises a casing or housing including a generally cupshaped base shell 21, a complementary inverted cupshaped hood or cover top shell 22 and an intermediate mounting and partition disk 23. All three of these eleta ments are adapted to be made from any suitable castable or moldable material and in a practical form are made of molded parts from suitable lightweight synthetic plastic material. At least the base portion or element 21 may be translucent or transparent since it is provided with a sump chamber 24 of substantial volumetric capacity for a supply of treating liquid L which can thus be checked visually as to quantity through the wall of the sump bowl. Means for securing the casing elements in separably assembled alignment, with the intermediate member 23 clamped between the opposing ends of the elements 21 and 22, herein comprise screws 25 which at the rear of the housing are accommodated in suitable, aligned ear flange and boss assemblies 27 whichare provided in symmetrical circumferentially spaced relation to serve as stabilizing supports when the assembly is backed into the bottom of the mounting socket 213. For convenience in manipulating the nebulizer unit into and out of the socket 24), the front portion of the cap 22 is provided with an integral handle 28.

For releasably retaining the nebulizer unit 14? within the supporting socket 2b, a spring latch 29 is mounted on the socket-defining flange of the door panel 1'5 (FIG. 6) to engage a rounded detent head 30 in pressure-yieldable releasable relation in a keeper socket 31 in the top end wall of the cover 22. Similarly, a spring arm latch 32 is mounted on the socket flange to engage a rounded pressure-releasable detent head 33 in a complementary keeper socket 34- provided in the base wall of the sump cup bowl 21. Through this arrangement, as the nebulizer unit It) is manipulated into the socket 26, light inward carnming pressure of the housing against the latch heads 30 and 33 overcomes the resilient bias of the spring latches and the latch heads then snap into the respective keeper sockets 31 and 34 to retain the nebulizer unit in place within the socket 20. When it is desired to remove the unit from the socket 20, this is readily accomplished by grasping the handle 23 and pulling outwardly thereon relative to the socket which results in camming the latch heads out of their keeper sockets and thereby releasing the unit.

Powered means are provided within the nebulizer housing for nebulizing the liquid L and driving it through a fixed nebulizer nozzle 35 (FIGS. 3, 5 and 6) which is circumferentially elongated at the front of the housing. This nozzle is defined by opposed flaring lip surfaces 37 provided on the bowl 21 and the intermediate member 23 and leading from a circumferentially elongated relatively narrow aperture or orifice 38 opening from the interior of the housing and more particularly the upper end of the sump chamber 24 and a roof chamber 39 defined by the lower side of the intermediate partition and mounting member 23. In addition to serving as a nebulizerdischarge orifice and nozzle, the nozzle 35 and the orifice 38 serve as a filling inlet through which a supply of the liquid L is adapted to be poured into the sump bowl. The flaring lip surfaces 37 provide a funnel-like lead-in into the sump chamber 24 to facilitate easy filling with additives.

Within the sump chamber 24, and operatively aligned with the discharge and filling aperture 38 is a nebulizer rotor 40 which is directly coupled coaxially with an electrical driving motor 41 housed within the chamber of the cover 22. Support for the motor is provided by the partition and mounting disk member 23 which has suitable upwardly extending motor supporting pylons 42 to which the motor frame is attached with a motor shaft 43 having an upwardly projecting portion journaled in a bearing assembly 44 and a downwardly projecting portion journaled in a bearing assembly 45 mounted in an upwardly projecting annular flange 47 on the partition member 23 between an integral annular horizontal flange 48 and a removable retainer disk 49. Below the flange 48 a sealing ring disk 50 engages about the motor shaft and prevents liquid from migrating to the bearing 45.

On its lower end portions, the motor shaft 43 is provided with a reduced diameter portion 51 to which a hub 52 of the rotor assembly 40 is corotatively attached as by means of set screws 53 whereby the rotor is supported for free spinning operation within the sump chamber 24 and the roof chamber 39. Through this arrangement, an annular nebulizing orifice 54 defined between the perimeter of concentric, substantially equal diameter spinning disks 55 and 57 carried by the hub 52 is aligned with the orifices 38. Desirably the disk 55 is integral in one piece with the lower end of the hub 52 and slopes upwardly generally dish shape, while the disk 57 is flat and is fined to the hub 52 on a peripheral upwardly facing rabbet shoulder 55; on the hub whereby the outer margin of the upper disk is maintained in predetermined narrow spaced relation to the underlying convergently related spinner orifice margin of the dished disk 55.

On the hub 52 concentric with the spinner disks is a downwardly projecting integral centrifugal suction pump tube 5% of at leastinternally frusto-conical shape progressively enlarging from a relatively small diameter lower end suction orifice 60 located adjacent the bottom of the sump 24 to a larger diameter head and from which a plurality of equidistantly spaced passage bores 61 lead to the dished spinner surface of the disk 55. As the spinning disk rotor 40 is spun at high speed, such as 15,000 rpm. by operation of the motor 41, the treating liquid is centrifugally pumped up the flaring inside wall of the pump tube 59 and is driven at high centrifugal acceleration toward the spinner orifice 54, causing eflicient nebulization and ejection of the nebulized liquid through the nebulizer nozzle 35. Except at the discharge orifice 3%, liquid leaving the spinner orifice is deflected by a sloping surface 62, defining the perimeter of the roof chamber 39, back into the sump 24.

Means are provided to avoid centrifugal displacement of liquid out of the sump 24 except through the nebulizing spinner orifice 5 1. To this end, the dished spinner disk 55 has a downwardly projecting outer marginal deflector skirt 63 which diverts back into the sump 2 any liquid that may migrate up the outer surface of the pump tube 59 and the undersunface of the dished spinner disk 55. As a precaution against escape of liquid from the sump under the spinner disks through the exit orifice 38, a horizontal deflector flange 64 is provided along the lower edge of the exit orifice. Any tendency towards development of a vortex in the liquid L within the sump 24 is counteracted by a series of circumferentially spaced vertical baffles 65 in the sump 24, fixedly supported by the bowl 21.

Power for driving the electrical motor 41 and control of the motor in operation of the associated drier 12 is effected by connecting the motor into the operating elec trical circuit of the machine when the nebulizer 10 is mounted on the door iii. In a desirable arrangement, the back of the housing adjacent juncture of the cover 22 with the mounting partition 23 defines a socket 67 within which connecting prongs 63 of an electrical connector 69 supported by a boss 7i) on the partition 23 are adaptedto mate with a complementary separable door-mounted electrical connector 71 (HUS. 6 and 8) to which are attached electrical leads 72 connected into the electrical control circuit of the machine. A cutout switch '73 such as a normally open micro-switch is suitably mounted on the door, such as adjacent to the base end of the unit receiving cavity socket 249, to be engaged by the base end of the nebulizer unit housing, and closed only when the nebulizer is in fully operating position Within the socket 213. For safety purposes, this assures that the electrical contacts of the connector '71 will be deenergized or dead in the absence of the nebulizer By virtue of the electrical connector 69 carried by the nebulizer unit, the unit can be used apart from the clothes drier by attaching an electrical cord thereto to energize the motor 41 for nebulizing any desirable treating liquid to be sprayed either as an article treatment, as an insect spray, as a room vaporizer, etc.

In order to facilitate use of the atomizer unit as an atomizer or sprayer separate from the clothes drier, the arrangement disclosed in FIGURE 7 including a separable manipulating handle 74 may be employed. Whereas the handle may be constructed and arranged to connect supportingly with the upper and lower ends of the nebulizer housing in the sockets 31 and 34 and effect electrical connection with the connector 69, the slightly simpler arrangement of the handle 74 and its connection to the nebulizer may be utilized. In this modified arrangement, a latch socket 31' in the top of the cover 22 received a rigid interlock lug 75 on the upper portion of the handle, while an interlock socket 34' in the rear of the nebulizer housing receives a releasable dog latch 77 engagea-ble with a keeper 78 extending partially across this socket to retain the handle in place for manipulating the nebulizer. The handle carries an electrical cord 79 connected to a digitally operable switch 80 conveniently located in the upper portion of the handle and electrically connected to an electrical connector 81 mounted adjacent to the interlock lug 75 for etfecting a coupling with an electrical connector 82 mounted adjacent to the keeper socket 31 and effecting a connection with the motor 41. Through this arrangement, selective energization of the motor 41 is readily effected through closing of the normally opening switch 80.

by depressing a switch button 84.

The nebulizer dispenser unit 10 of FIGURE 7 is structurally and ifunctionally substantially identical to the unit as described in connection with FIGURES 1-6 except for relocation of the keeper sockets 31' and 34' and of the electrical motor connector 82. Use of the modified unit in a clot-hes drier, therefore, requires only relocation of the retaining latch mechanism on the door and the doorcarrled electrical connector to accommodate the relocation of the complementary structures on the modified unit.

In a typical drying and treating cycle, wherein, for example, bleaching and drying of a batch or load of white materials such as clothing and household linens, and the like, is to be accomplished, the wet washed materials are placed into the treating chamber or compartment within the rotary drying drum 13. The nebulizer 1G with the sump chamber 24 thereof substantially filled with a suitable amount of a liquid bleach such as hydrogen peroxide is mounted in the cavity socket 20 of the drier door. This closes the safety switch 73 (FIGS. 6 and 8).

Upon closing the drier 11, a normally open switch 85 (FIGS. 1 and 8) in the drier control circuit and mounted on the cabinet 12 is closed by the door, and the drier is ready to begin a drying, treating cycle. Then, a sequential controller 87 has a timer motor 88 thereof adjusted by means of a knob 89 to the Start position of the drying operation, indicated at A in FIGURE 9. This closes timer switches 90, 91 and 92. Closing of the switch completes the circuit through a drive motor 93 for driving the rotary drum 13 to tumble the materials therein and also drives an air blower (not shown) for moving heated drying air through the tumbling material to be treated and dried. When the motor 93 reaches a predetermined speed, it closes a centrifugal switch 94 to complete a circuit for energizing an air heater 95. This heater circuit is also controlled by the timer switch 91. Closing of the switch 92 complete the energizing circuit for the nebulizer motor 41 and the nebulizer will spray the bleach onto the dispersed tumbling materials in a fine mist, thereby evenly distributing the bleach throughout the wet material.

At the end of the spraying period, shown at B in FIG- URE 9, at least all of the liquid required from the sump 24 of the nebulizer 10 will have been dispensed, and the timer switch 92 is opened to deenergize the motor 41; However, the drier continues on to the end of a typical drying sequence, including a cooling down period shown at C in FIGURE 9.

It will be understood that in the case of a drying-bleaching operation, it is necessary to subject the fabrics to fairly elevated temperatures, such as on the order of F. to liberate the oxygen from the bleach to accomplish the bleaching.

However, in the use of some other additives, such as Water repellants, fabric softeners, water for dampening, etc., it is often recommended that they be applied to the wet or dry materials without the addition of heat. In the use of such non-heat additives, an Air Cycle setting of the sequential controller 87, as shown at D in FIG- URE 9, effects dispensing of the additives to the materials in the rotary drum 13 without subjecting the materials to heat during addition of the additive. After addition of the additive in the Air Cycle setting, ihe user of the drier may remove the nebulizer 10 from the door of the drier to use the nebulizer as a portable hand sprayer, and reset the control knob 89 to the beginning of the Drying cycle portion of the controller 87 to remove moisture from the materials, if so desired.

Although minor modifications might be suggested by those versed in the art, it should be understood that I wish to embody within the scope of the patent warranted hereon all such modification as reasonably and properly come within the scope of my contribution to the art.
