Definitions

  • the present invention relates to a home appliance, and more particularly, to a drum device for minimizing noise from a drum in which washing or drying is in progress in a washing machine or a drying machine.
  • the dryer is an apparatus for drying objects, such as laundry, introduced into the drum by blowing air heated by an electric heater or a gas burner.
  • FIG. 1 illustrates a disassembled perspective view of key parts of a related art dryer. As shown, a drum 1 is installed in a cabinet (not shown) that forms an outside shape of the dryer.
  • the drum 1 is cylindrical, with opposite opened ends, and has a belt groove 2 along an outside circumference of a middle of the drum 1 for winding a drum belt 4 driven by a motor 3 .
  • the drum 1 has a drying chamber 5 therein for carrying out drying.
  • the drum 1 has a plurality of baffles 6 for turning drying objects in the drying chamber 5 . Since the drum 1 has high temperature air circulating inside of the drum 1 , the drum 1 is in general formed of a metal, for an example, stainless steel.

  • the gas nozzle 22 is fitted to one side of a valve 30 for controlling gas supply.
  • the reference numeral 23 denotes a gas supply tube 23 connected to the valve 30 .
  • the gas nozzle 22 at one side of the valve 30 is fitted to an inlet to the mixing tube 24 opposite thereto.
  • the gas sprayed from the gas nozzle 22 and external air introduced through the inlet of the mixing tube 24 i.e., the primary air, are mixed inside of the mixing tube 24 .
  • the air to the air supply duct 12 is heated to a relatively high temperature by heat supplied from the gas burned as the gas passes through the hot air duct 20 .
  • the hot air is introduced to the inside of the drying chamber 5 in the drum 1 through the air supply duct 12 . After absorbing moist contained in the laundry in the drying chamber 5 , the hot air escapes the drying chamber 5 owing to a suction power of the blower 17 .
  • the air is involved in filtering dust and lint as the hot air passes through the lint filter fitted to an inside of the lint duct 15 .
  • the laundry inside of the drum 1 of a metal repeats a process of being lifted and dropped by the baffles 6 as the laundry rotates along with the drum 1 .
  • fittings to the laundry such as buttons, zippers, clips, collide with a surface of the metallic drum when the laundry drops inside of the drum 1 , to generate noise.
  • An object of the present invention designed for solving the foregoing various problems, lies on an effective insulation of vibratory noise occurred as fittings to laundry, or metallic foreign matters, collide with an inside surface of the drum in a home appliance during the drum rotates.
