Definitions

  • This invention relates generally to laundry equipment and more particularly to a clothes dryer of the type in corporating a stationary receptacle or drum for receiving fabrics such as clothing and the like to be dried, a warm air system for supplying warm air into the drum to dry the fabric and tumbling means for tumbling, agitating and loosening of the fabric in the stationary drum as the warm air is being circulated therethrough in order to thoroughly dry the fabric in a minimum amount of time.
  • prior art clothes dryers comprise a dryer cabinet and a rotatable horizontally disposed internally and integrally baffled drum with the front end of the drum aligned with an access door in the front wall of the cabinet for loading and unloading clothes into the drum.
  • Warm air systems incorporated in such prior art arrangements are by design usually restricted in that air inlet and air outlet ducts or conduits are required to have openings which do not communicate directly with the interior of the drum.
  • the flow path of the warm air within the drum is therefore substantially reduced. If the air enters and leaves the drum through the same wall of the drum there may be a tendency to short-circuit the drum so that only a portion of the air stream actually circulates through the drum.
  • a stationary drum for receiving fabrics to be dried.
  • the drum comprises a cylindrical peripheral wall and two end walls which may also conveniently form the front and back of a generally rectangular cabinet for housing the stationary drum.
  • Independently movable bafiles are provided within the drum to accomplish an agitating or tumbing function.
  • the baffles are driven from exteriorly of the drum by drive means connected to the baflles through only a minor section of the drum. Accordingly, air inlet and outlet openings may be placed about the periphery of the drum in almost any desired advantageous position without concern for problems inherent in transfer of drying air to and from rotating drums.
  • the warm drying air may be circulated substantially more thoroughly through the interior of the drum in order to more satisfactorily dry the fabrics in an appreciably reduced time and with attendant savings in costs of operation.
  • a novel bafile arrangement ensures thorough turnbling of the fabrics and a drive arrangement provides for driving the baffles and a blower in the warm air system from a single motive source.
  • Another object of the present invention is to provide awarm air system for a clothes dryer wherein the warm air enters and leaves through opposite portions of the drum, thereby improving the warm air flow within the drum.
  • Yet another object of the invention is to provide a clothes dryer incorporating a stationary dryer drum with warm air supply and discharge conduits in open communication with any selected portion in the interior of 3,321,845 Patented May 30, 1967 the drum for circulating warm air therethrough, at least one of such conduits opening into the interior of the drum through the cylindrical peripheral side wall of the drum.
  • Another object of the invention is to provide a clothes dryer wherein the dryer drum is non-rotatably mounted within the cabinet to facilitate connection of air conduits to the peripheral side wall of the drum to provide crossflow of warm air within the drum and also wherein baffle members are arranged within the drum contiguous to the peripheral side wall to move relative to the drum to provide a tumbling action to the fabrics.
  • Still another object of the invention is to provide an arrangement whereby a blower for the warm air system and also tumbling means for the fabrics are both driven from a single motive source.
  • Still another object of the invention is to provide a clothes dryer which is simple in design and construction, which reduces drying time and which is extremely efficient with resultant savings in operating costs.
  • FIGURE 1 is a front elevational View of a clothes dryer incorporating the principles of the present invention with portions of the front panel of the dryer cabinet cut away to disclose the relative disposition of parts;
  • FIGURE 2 is a side elevational view of the dryer of FIGURE 1 with portions of a side panel of the cabinet cutaway;
  • FIGURE 3 is an enlarged fragmentary sectional view of the dryer taken substantially along the lines III-III of FIGURE 1 and with parts removed for clarity;
  • FIGURE 4 is an enlarged detailed sectional view of a novel bafile and baffle driving arrangement constructed in accordance with the principles of the invention.

  • a stationary receptacle or drum 19 Housed within the cabinet 11 is a stationary receptacle or drum 19 forming a generally cylindrical treatment zone for receiving fabrics such as articles of clothing and other materials to be dried.
  • the drum 19 is generally horizontally disposed and comprises a fixed cylindrical peripheral side wall 20 closed at its opposite ends by vertical front and rear panels 12 and 13, respectively.
  • the drum 19 is mounted in firm assembly within the cabinet 11 and is connected in fixed assembly to fixed support members of the cabinet in any suitable manner.
  • An access or closure door 23 with a handle 25 is mounted on the front panel 12 of the cabinet 11 by means of binge members 24 and controls an opening for loading wet fabrics into and removing dried fabrics from the receptacle or drum 19 and for that purpose an opening 26 is formed in the front panel 12 in registry with the door 23 to facilitate ingress and egress to and from the drum.
  • a seal member 35 on the door provides an air seal between the door 23 and the front panel 12..
  • a Warm air system is provided within the cabinet and comprises, in the exemplary embodiment illustrated, an air blower such as a centrifugal fan 27 which discharges through an air duct or conduit 28.

  • the duct 23 be placed in direct open communication with the interior of the drum 19 through an air inlet or supply opening 29 formed in the periphery of the drum for example in the peripheral wall 20 of the drum 19.
  • the opening 29 is covered by a screen 29a to prevent fabrics from falling into conduit 28.
  • an air outlet duct 30 communicates with the interior of the drum 19 through an opening 31 formed in the back panel 13 of the cabinet 11.
  • the heated air which enters the drum through the opening 29 must circulate substantially across the axial length of the drum before it is discharged through the outlet opening 31.
  • drum openings could be functionally reversed, that is, warm air could be introduced into the drum through the opening 31 and discharged from the opening 29 or, alternatively, both the inlet and Q I the outlet openings could be formed in the side peripheral wall 20 of the drum 19. Also, the warm air could well be drawn through the drum instead of being pushed as illustrated in the drawings.
  • a collar 32 of the duct 30 protrudes from the rear panel 13 of the cabinet 11 in order to accommodate additional duct work, if desirable.
  • baffle members 33 are situated within the drum 19 preferably contiguous to an inner surface 34 of the peripheral wall 20 and moved in a circumferential circular path about the interior of the drum in order to engage and to provide a tumbling action for the fabrics.
  • the baflie members 33 are mounted on and driven by means of a baffle drive apparatus indicated generally at reference numeral 36 which comprises a continuous ring shaped bafile carrier member 51 mounted on the drum 19 for rotation relative thereto and a belt 37 wrapped drivingly about the periphery of the baflie carrier member 51 and driven by means of a pulley r sheave member 38 mounted on a drive shaft 39 of a suitable motive source, :such as an electric motor 40.
