Definitions

  • the present disclosure relates to a combination washer/dryer machine and, more particularly, to a heating circuit in the combination washer/dryer machine.
  • the combination washers/dryers utilize ducts to provide hot air through a small port or small local grille inside the tumbling cavity.
  • the temperature are generally higher. This is less desirable on a combination washer/dryer where the majority of components are polymeric in nature.
  • the present disclosure provides a heating circuit that generates uniform drying air. Thus, this eliminates a localized drying area.
  • the present disclosures provides a heating element secured within the cabinet. This eliminates vibration of components within the cabinet cavity.
  • the present disclosure provides a rigidly mounted heater element and duct. This eliminates or avoids high temperature flexible duct work or piping. Additionally, the present disclosure provides a larger area in the tumbling cylinder for the distribution of the heated air through the clothes.
  • a combination washer/dryer machine comprises a cabinet, a tub positioned in the cabinet and a drum rotatably positioned in the tub.
  • a heater is secured to the tub.
  • the heater includes a duct to provide heated air from the heater to the tub which, in turn, is distributed into the drum.
  • the duct is likewise secured to the tub.
  • the tub includes at least one opening to receive heated air from the duct.
  • the drum includes apertures in its end surface providing at least 50 cm 2 of open area of the area of the end surface.
  • the heater includes a metal housing to be secured to the tub.
  • the heater duct is also metal.
  • the duct can be an independent separate part from the heater.
  • a combination washer/dryer machine comprises a cabinet, a door enabling access into the cabinet, and controls for operating the washer/dryer machine.
  • a washing circuit and drying circuit wash and dry the clothes within the drum.
  • a heater is secured to the tub.
  • the heater includes a duct to provide heated air from the heater to the tub. The heated air is distributed into the drum.
  • the duct is likewise secured to the tub.
  • the tub includes at least one opening to receive heated air from the duct.
  • the drum includes apertures in its end surface providing at least 50 cm 2 of open area of the end surface.
  • the heater includes a metal housing secured to the tub.
  • the heater duct is also metal.
  • the duct can be an independent separate part from the heater.
  • a combination washer/dryer machine tub and drum comprises a tub and a drum inside of the tub.
  • a heater is secured to the tub.
  • the heater includes a duct to provide heated air from the heater to the tub. The heated air is distributed into the drum.
  • the duct is likewise secured to the tub.
  • the tub includes at least one opening to receive heated air from the duct.
  • the drum includes apertures in its end surface providing at least 50 cm 2 of open area of the end surface.
  • the heater includes a metal housing to be secured to the tub.
  • the heater duct is also metal.
  • the duct can be an independent or separate part from the heater.
  • FIG. 1 is a perspective view of a combination washer/dryer machine in accordance with the disclosure.
  • FIG. 2 is a rear perspective view of the combination washer/dryer machine of FIG. 1 .
  • FIG. 3 is a breakaway perspective view of the washing machine of FIG. 1 .
  • FIG. 4 is a breakaway top plan view of the combination washer/dryer machine of FIG. 1 .
  • FIG. 5 is a breakaway perspective view of FIG. 2 .
  • FIG. 6 is a cross-section view of FIG. 5 along line 6 - 6 thereof.
  • the combination washer/dryer machine 10 includes a cabinet 12 with a plurality of panels 14 .
  • the front panel 16 includes a door 18 to enable access into the cabinet 12 .
  • a control panel 20 is illustrated on the front panel 16 of the cabinet 12 .
  • the combination washer/dryer machine 10 includes a tub 30 with a drum 32 rotatably positioned inside of the tub 30 .
  • a washing circuit 34 is illustrated coupled with the tub 30 .
  • a drying circuit 36 is illustrated coupled with the tub 30 .
  • a heating element 40 is positioned on the tub 30 .
  • the heating element 40 includes a housing 42 that is secured, via fasteners, to the tub 30 .
  • the heating element housing 42 is generally a metal housing surrounding a calrod heating element positioned within the housing 42 .
  • the heating element 40 includes a duct 44 that is coupled with the tub 30 .
  • the duct 44 enables the heated air to pass into the drum 32 through the tub 30 .
  • the duct 44 has a desired design and is generally manufactured from a metallic material.
  • the duct 44 is secured to the tub 32 , via fasteners, to prohibit movement of the duct as well as the heating element 40 .
  • the rigid mounting of the heating element 40 and duct 44 to the tub enables the design to avoid high temperature flexible duct. Also, this eliminates movement of the heating element and duct caused by vibration.
  • the tub 30 includes an opening 50 to enable passage of the heated air into the drum 32 .
  • the opening 50 may be a single large opening. Alternatively, a plurality of smaller openings. may be present in a desired area to provide for structural integrity.
  • the drum 32 includes an end portion 54 .
  • the end portion 54 has a plurality of apertures to enable the heated air to pass into the drum 32 .
  • the apertures providing at least 50 cm 2 of open area of the total area of the end portion 54 .
  • the current design provides 180 cm 2 of open area. Accordingly, this enables adequate heated airflow to travel through the apertures and into the tumbling clothes for drying purposes.
  • the open area of the apertures provides for the desired flow into the drum 30 to dry the clothes within the drum 30 .
  • drying is initiated.
  • the control panel initiates heating of the heating element 40 .
  • the blower fan in the drying circuit is initiated. This blower draws the heated air from the heating element 40 through the duct 44 into and through the opening 50 in the tub 30 . After this, the air is drawn into the drum 32 via the apertures on the end portion 54 of the drum 32 . The air continues to exit the drum 32 into the tub 30 . The air is moved to the blower and ultimately out of the cabinet via the exhaust tube.
  • the heated air is drawn through the drum 32 to efficiently dry the clothes within the drum 32 .
  • the drying time is thus substantially reduced.
