ABSTRACT OF THE DISCLOSURE
A generally small capacity automatic clothes dryer is shown utilizing a draw-through air circulation system and having a unitarily molded air duct defining an inlet chamber, fan scroll portion, and air outlet or exhaust chamber for mounting on the front panel of the dryer housing in air flow communication between the access opening leading to the interior of the tub and through which the moist air exits the tub in a confined path leading to the duct, and a for-wardly facing discharge opening in the front panel.
Description
8~
This invention relates generally to automatic clothes dryers and more particularly to an air flow duct structure and arrangement in a forwardly exhausting dryer.
Description of the Prior Art:
In regular size domestic clothes dryers (i.e.
those capable of drying within a certain limited time a 10-12 pound load of clothes) it is generally necessary to exhaust the moist warm air exteriorly of the building housing the dryer to maintain the air within the building at an acceptable comfort level with respect to temperature and vapor content. Thus, the air flow system for such a dryer commonly includes a duct directing the exhaust air through the rear panel of the dryer housing for connection with a flexible pipe leading to an exterior vent. However, compact automatic dryers having a smaller clothes capacity and using less power generally permit exhausting the air -within the building or room containing the dryer without ' exceeding accepted comfort level for heat and moisture.
This is aided by the fact that such compact dryers generally are paired with automatic washers which have a relatively high centrifuging speed in the spin cycle such that the moisture content of the clothes, removed therefrom the placed in the dryer, is much less.
Also, in that these compact dryers are generally readily movable, as being mounted on castors, they are easily serviceable from the rear panel as opposed to the larger stationary dryers which, for convenience, are aenerally serviceable from the front panel.

Taking these facts into consideration along with the desire to provide a simple and inexpensive structure for a compact dryer it was determined that the air flow system could be greatly reduced in complexity and cost and particu-larly suitcd to a smaller capacity dryer by forwardly ~ I , .
.. .....
exhausting the dryer air through a unitarily molded air intake, fan scroll and air discharge chamber mounted on the front panel of the machine.
According to the present invention there i8 provided an improved air circulation system for a clothes ` dryer having a cabinet structure housing a rotatable clothes basket with a forwardly facing opening, drive means for rotating the basket and wherein the cabinet includes a front panel having a first opening comprising an access opening generally concentric with the basket opening, a second opening generally subadjacent the access opening and a third opening spaced from the second opening, a door hingedly mounted on the panel for covering both the first and second openings when the door is in a closed position and means including the door and the ;~
front panel defining a confined air flow passage between the first and second openings on the forward face of the -front panel when the door is closed. A molded one-piece - air duct and fan scroll define in cooperation with the inner face of the panel an air inlet chamber in effective sealing engagement with the panel surrounding the second ,- -opening. An air exhaust duct is in effective sealing engagement with the panel surrounding the third opening, and a fan scroll means is provided for housing a rotatable ~ -fan, the means having a wall common to both the inlet chamber and the exhaust duct including an inlet opening between the inlet chamber and the fan housing and an outlet between the housing and the exhaust duct.

DESCRIPTION ~F THE PREFERRED EMBODIMENT
Referring initially to Fig. 1, an automatic clothes dryer 10 incorporating the air flow apparatus ;~ and system of the present invention is shown. However, for the most part, the dryer has structure well known in the prior art such as ~"~ 3 .
,, ~ lr34~
~n outer cabinet 12 housing a rotatably mounted forwardly open clothes tub 14. The cabinet includes a back panel (not shown) having sufficient louvers or openings therein to permit ambient air into the interior thereof and a front panel 16 having an inset portion 18 defining a first opening 20 generally concentric with the opening of the interior ; tub for access to the tub and a second opening 22 sub-adjacent the first opening and covered by a filter or screen 24.
A forwardly opened door 26 is hingedly attached to the front panel 16 for movement between an open position shown and a closed position wherein it fits generally within the inset area 18 of the front panel and covers both open- .
- ings 20 and 22.
: Still referring to Fig. 1, it is seen that the -. inner face 28 of the door 26 has a portion 30 formed out- ~ .
wardly from the general plane so as to extend into the . access opening 20 a sufficient distance to prevent the clothes, tumbling in the tub 14, from becoming lodged in .: -the space between the inner face of the door and the front :
panel when the door is closed. Also, the door 26 has a gasket 32 attached, as by cementing, so that in a closed position there is an effective air seal encircling both openings 20 and 22 to form a confined air flow path as will .`
be described later. The front panel 16 also contains a third opening (or plurality of spaced openings as shDwn) 34 generally adjacent the floor or bottom of the machine and outside the area covered by the door for a purpose to be . described. --Referring now to Figs. 2 and 3, a portion of the ~ - .
interior of the dryer housing is shown generally adjacent the front panel 16. Thus, it is seen that the dryer includes ~ sb/r ` `'~ ' 1'~4`~
~ drive motor 36 having a shaft 38 extending rearwardly - and drivingly coupled, through a belt and pulley mechanism ~0 to the tub 14. The forwardly extending motor shaft 42 is coupled to a centrifugal fan 44 enclosed in a scroll-shaped housing 46 which forms a part of a unitarily molded air duct 48 which also includes an inlet chamber 50 and exhaust chamber 52 as hereinafter more fully explained.
Still referring to Figs. 2 and 3 in conjunction with Fig. 4 it is seen that the unitarily molded integral air duct 48 just mentioned is essentially a forwardly open ` box-like structure having a planar back wall 54 surrounded by forwardly extending peripheral side walls 56, a top wall ` 58 and bottom wall 60. The length of the box is such as to generally extend across the back face of the front panel 16 with the top wall 58 thereof notched as at 62 to receive - ~-the inset portion 18 of the panel. Also, the height of the box is such that it extends from above the second opening ' 22 in the front panel 16 to below the third opening 34 --generally adjacent the floor, in the panel.
;~ 20 The leading edge of the peripheral walls 56, 58 and 60 of the box are in intimate contact with the rear face of the front panel 16 for effective sealing engagement - -therewith and held thereon by screws 64. ~Y
The forwardly open box is partitioned by a hori-zontal forwardly extending dividing wall 66 which extends between opposing side walls 56 and projects forwardly so as -to be in intimate facing engagement with the rear face of the front panel 16 intermediate the openings`22 and 34 therein. ^
That portion of the box-like structure thus formed by back wall 54, opposing side walls 56, top wall 58, and partition-ing wall 66 and disposed directly rearwardly of the second -opening 22 thus comprises the air intake chamber 50. And, sb/r ' ,, . ~. ~
1~4~
`hat portion formed by the back wall, opposing side walls, bottom wall, and partitioning wall and directly rearwardly of the third, or outlet, opening 34 in the front panel com-prises the exhaust chamber 52.
The fan housing 46 extends rearwardly from the back face of the back wall 54 and is defined by a contoured peripheral wall 68 in the general shape of a scroll compris-ing an enlarged circular periphery adjacent one side leading ` into a narrower elongate fan discharge portion extending across the back wall to the other side. As best seen in Fig. 2, when assembled, the fan 44 resides within the cir-cular periphery of the housing 46. The back wall of the box-like structure includes an aperture 70 which, on the front side, is in the area of the intake chamber 50 and also generally coaxial with the fan so that the fan and intake chamber are in air flow communication therethrough. Further, as best shown in Fig. 4, the back wall 54 of the box-like structure includes an aperture 72 in the lowermost area of the scroll-shaped fan housing 46, and extending generally along its lenght, leading therefrom to the exhaust chamber 52 on the front face of the box. Forwardly projecting fins 74 generally guide the air flow to direct it into and through the exhaust chamber.
Still referring to Fig. 4 it is seen that a plate 76 is attached to the back edge of the wall 68 of the fan housing in an effective sealing engagement as by screws through appropriately spaced bosses in the wall. The plate 76 defines an enlarged opening 78 in the area corresponding to the fan position and sized so as to be able to receive the fan therethrough. As seen in Figs. 2 and 3, this opening 78 is closed when the fan and housing are in the assembled position by a sealing plate 80 having a central sb/ ~
1~4f~
`~perture 82 for receipt of the motor shaft 42 therethrough and a flange area 84 of greater diameter than the opening 78 for sealing engagement with the plate 76 about the opening 78. A compression spring 86 is coiled about the motor shaft 42 with one end abutting the motor mounting -frame 88 and the other end abutting the sealing plate 76 to resiliently urge the plate axially outwardly toward the fan 44.
Thus, the fan 44 is assembled in the housing 46 through the opening 78, the sealing plate 80 abuts the ` back plate 76 and compresses the spring 86 which maintains the two plates 76, 80 in sealing engagement. The outward force of the spring 86 is also useful in maintaining the front wall structure of the box tight against the front panel 16 in cooperation with the previously mentioned mounting screws 64. The back plate 76 also contains a second opening 90 generally in alignment with the elongated discharge portion of the fan of the scroll-shaped fan housing 46 which, for the most part, is maintained closed by a screwed-on plate 92 and for a purpose to be described later.
With the fan 44 operating as in a drying cycle, the air is drawn into the dryer housing 12 through the back panel, and into and through a heating chamber and the clothes ~`
tub as is well known in the art. From there the air flow is as shown by arrows in Figs. 3 and 4 which show the warm ;
moist air exiting the tub 14 through its open front and -access opening 20 in the front panel 16 and into the con-fined area between the closed door and the front panel as sealed by the gasket 32. From there the air is drawn into the intake chamber 50 through the filter 24 and opening 22 in the front panel. The air then enters the scroll-shaped s~/~ ,.,s , .
1~D4f.~3Sl ~an housing 46 to be discharged through the openiny 72 therein to the forwardly facing exhaust chamber 52 which is open to the room through the bottommost openings 34 in the front panel. It is noted that the front panel 16 in this area is also inset with an upwardly tapering wall 94 de-fining the openings 34. In this way the air flow is given a final, upwardly directed, path so that its contact with adjacent cooler surfaces, typically the floor, which may be cool enough to condense vapor in the exhaust air, is minimal.
Thus, the air flow duct in the described dryer comprises this single one-piece molded boxlike structure which is mounted on and utilizes the front panel of the dryer housing to form a part thereof.
In those instances wherein it is desirable to have the dryer exhaust rearwardly, as is commonly done in the larger capacity machines, the above-described structure can, by simple modification shown in Fig. 4, accommodate the requirements. Thus, by merely blocking the front lowermost openings 34 in the panel 16 as by attaching a strip of material 96 thereover, and removing the plate 92 from its normally closed opening 90 on the back plate 76 of the fan housing and inserting a conduit pipe 98 leading to the - desired exhaust location, the forward exhaust is blocked and replaced by a confined rear exhaust.
