Definitions
- the present disclosure relates to combination washer/dryer machines and, more particularly, to a combination washer/dryer machine with an electromagnetic seal to maximize the drying rate of clothes tumbling in the machine.
- drying air would be forced to enter into the drum. Accordingly, with all the drying air forced into the drum, this would, in turn, reduce drying cycle time.
- a combination washer/dryer machine comprises a rotatable drum inside of a cabinet.
- the drum has an external surface.
- a tub is positioned inside of the cabinet.
- the drum is rotatable in the tub.
- the tub has an inner surface.
- An electromagnetic seal extends between the external surface of the drum and the inner surface of the tub during a drying operation to minimize bypass of drying air.
- the electromagnetic seal includes a bellows seal with a magnet in the bellows seal and an electromagnetic setup.
- the rotatable drum has a cylindrical shape with a cylindrical sidewall and an end plate. The seal is positioned in contact with the exterior surface of the cylindrical sidewall.
- the electromagnetic setup is in contact with a wall of the tub.
- the bellows seal and an electromagnetic setup are positioned in contact with the endwall of the tub.
- a combination washer/dryer comprises a cabinet with a door to enable access into the cabinet.
- the controls operate the washer/dryer machine.
- a washing system and drying system are provided.
- a rotatable drum is positioned inside the cabinet.
- the drum has an external surface.
- a tub is positioned inside the cabinet.
- the drum is rotatable inside the tub.
- the tub has an inner surface.
- An electromagnetic seal extends between the exterior surface of the drum and the inner surface of the tub during the drying operation to minimize bypass of drying air around the drum.
- the electromagnetic seal includes a bellows seal with a magnet in the bellows seal and an electromagnetic setup.
- the rotatable drum has a cylindrical shape with a cylindrical sidewall and an end wall. The seal is positioned in contact with the exterior surface of the cylindrical sidewall.
- the electromagnetic setup is in contact with a wall of the tub.
- the bellows seal and an electromagnetic setup are positioned in contact with the end wall of the tub.
- a combination washer/dryer machine drum and tub combination comprises a drum rotatably positioned inside the tub.
- An electromagnetic seal extends between an exterior surface of the drum and an inner surface of tub during the drying operation to minimize bypass of drying air around the drum.
- the electromagnetic seal includes a bellows seal with a magnet in the bellows seal and an electromagnetic setup.
- the rotatable drum has a cylindrical shape with a cylindrical sidewall and an end plate. The seal is positioned in contact with the exterior surface of the cylindrical sidewall.
- the electromagnetic setup is in contact with a wall of the tub.
- the bellows seal and an electromagnetic setup are positioned in contact with the endwall of the tub.
- the combination washer/dryer machine includes a cabinet 14 having a plurality of panels 16.
- the front panel 18 includes a door 20 to enable access into the combination washer/dryer 10.
- Controls 22 are positioned on the front panel 18. The controls 22 control the operation of the combination washer/dryer machine.
- the combination washer/dryer machine includes a drum 30 rotational positioned within a tub 32.
- the drum is rotated via a motor 34 and a shaft 36.
- a conventional washing circuit 40 provides for washing of the clothes within the drum 30.
- a heating circuit 50 provides heat for drying the clothes within the drum.
- the heating circuit 50 includes a heater 52 with a conduit 54 passing heated air into the tub 32.
- the drum 30 includes apertures 33 in the end plate that enables the heated air to enter into the drum 30. Also, the drum 30 includes apertures 35 in the cylindrical wall.
- the heated air exits the drum 40 via the gap G as seen in FIG. 2 .
- An outlet 38 on the tub 32 enables the exit of air.
- Piping or conduit 56 connects the outlet 38, via a blower 58, to an exhaust tube 60.
- the exhaust tube 60 is connected with piping in the building to exit to ambient.
- a gap 70 is formed between the drum and the tub 32.
- the gap 70 provides for the recovery of water or the like between the drum 30 and tub 32.
- the drum has a cylindrical sidewall 72 and an end plate 74.
- the tub 32 has cylindrical wall 76 and an end wall 78.
- the external surface of the sidewall 72 and end plate 74 face an inner surface of the tub 32.
- a seal 80 is connected between the drum 30 and tub 32.
- the seal can be connected to either the drum 30 or the tub 32 as illustrated.
- the seal 80 is positioned either between the end faces 74, 78 of the drum 30 and tub 32 or the cylindrical side surfaces 72, 76 of the drum 30 and tub 32.
- the seal 80 includes a bellows seal 82 and an electromagnetic setup 84.
- the bellows seal 82 includes a securement portion 86, a bellows portion 88 and a retaining portion 90.
- the retaining portion 90 includes a magnet 92 retained within the retaining portion 90.
- the electromagnetic setup 84 is activated which, in turn, draws the magnet 92 toward the electromagnetic setup 84. As this occurs, as illustrated in FIG. 4 , the bellows portion 88 closes the gap between the drum 30 and tub 32.
- the seal 80 includes a securement portion 94 securing it to the end surface 78 of the tub 32.
- the electromagnetic setup 84 is activated which pushes the magnet 92 away from the electromagnetic setup 84. As this occurs, it expands the bellows portion 88 to close the gap between the drum 30 and tub 32 as seen in FIG. 6 .
- the gap is narrowed.
- the drying air is forced into the drum 30 and does not bypass the drum 30. Accordingly, drying of the clothes within the drum 30 is more efficient and the drying time period is reduced.
