The present invention relates to a drum washing machine, and more particularly, to a dry drum washing machine and a control method thereof for performing a blowing function during the dehydration stroke.

In general, a washing machine performs washing strokes, rinsing strokes, and dehydrating strokes by rotating a rotating tub and a pulsator through a driving force of a motor. It is a device that washes using friction of water and a rotating tub.

These washing machines are classified into pulsator type, stirring type, drum type, etc. according to the washing method.

Here, the drum washing machine is a device for washing laundry by rotating the drum by the driving force of the motor in a state in which detergent, washing water, and laundry are put into the drum. The laundry is less damaged and the laundry is not tangled, and the laundry is pounded and rubbed. It has the advantage of making a difference.

Hereinafter, with reference to the accompanying drawings illustrating a configuration of a general dry drum washing machine as follows.

1 is a side view showing the configuration of a general dry drum washing machine.

As shown in FIG. 1, a general drying drum washing machine is installed in the cabinet 10 to store washing water, and a hot air inlet 20a is formed at the front side and a hot air discharge is formed at the bottom side of the rear side. A tub 20 having a ball 20b, a drum 30 rotatably installed in the tub 20 and having a plurality of hot air passing holes 30a having a predetermined arrangement on a front surface thereof; The heater 41 and the blower fan 42 are built into the tub 20 so as to be fixed on the outer peripheral surface of the tub 20 and generate hot air, and one end thereof is provided at the hot air inlet 20a of the tub 20. One end is connected to a drying duct 40 connected to supply hot air generated therein to the drum 30, and a hot air discharge hole 20b at a lower rear side of the tub 20 and the drying duct 40. ) Is installed at the rear side of the tub 20 so that the other end is connected to the tub 20 To remove the moisture contained in the discharged air is sent to the drying duct 40 is configured to include a condensing duct (50).

Here, the tub 20 is preferably injection molded of a plastic material, the drum 30 is preferably formed of a stainless steel material.

On the other hand, the drying duct 40 is fastened and fixed to the upper side outer surface of the tub 20 by a fastening member such as a screw, the drying duct 40 between the tub 20 and the drying duct 40. The heat shield plate 43 is installed to prevent the heat generated in the heat transfer to the tub (20).

That is, the heat shield plate 43 is first fixed to the outer surface of the tub 20, the drying duct 40 is the heat shield plate 43 by a fastening member such as a screw in a state where the heat shield plate is fixed to the tub. It is fixed on the phase.

On the other hand, the drum 30 penetrates the tub 20 and is axially connected to the drum 30, a rotor 62 coupled to the rear end of the shaft 61, and the rotor 62. Preferably rotated in a direct drive method by the outer rotor type motor consisting of a stator 63 located inside, but is not necessarily limited thereto.

In addition, the upper surface of the drying duct 40 may be configured to heat dissipation means such as heat radiation fins to prevent the drying duct upper surface from overheating.                         

The action of the dry-use drum washing machine of the present invention configured as described above is as follows.

First, the hot air inlet 20a is formed at the upper front of the tub 20, and the hot air outlet 20b is formed at the lower rear side of the tub 20.

This makes the inflow direction of the hot air flowing into the drum 30 and the discharge direction of the hot air discharged into the condensation duct 50 to be in a diagonal direction, so that the hot air is evenly spread throughout the drum to dry the laundry evenly. This is to discharge afterwards.

That is, the hot air passing through the front of the drum 30 is formed in such a way that the strength of the front part of the drum 30 is not reduced but the flow path cross section can be maximized.

Thus, the hot air inlet hole 20a and the hot air inlet hole 20a communicate with each other even though the drum 30 is rotated by forming the hot air passage hole 30a in an effective arrangement form over the entire front surface of the drum 30. The hot air introduced into the tub 20 through the inlet 20a may be smoothly supplied into the drum 30 through the hot air passing hole 30a provided in the front of the drum 30.

On the other hand, the heat shield plate 43 is installed in the lower portion of the drying duct 40, the heat shield plate 43 prevents the heat generated in the drying duct 40 is transmitted to the tub (20).

In addition, the drying duct 40 is fixed on the outer peripheral surface of the tub through the heat shield plate, so that the drying duct 40 and the tub 20 do not need to install a gasket for absorbing vibration. do. This is because the drying duct 40 is fixed to the tub 20, so that when the tub 20 flows or vibrates, the drying duct 40 also flows or vibrates with the tub.

Of course, it is easily understood by those skilled in the art that a sealing member may be installed at the connection portion of the drying duct 40 and the tub 20 to prevent leakage of heat generated from the drying duct 40.

On the other hand, the condensation duct 50 is also directly fixed to the rear of the tub 20, so that the condensation duct 50 and the tub 20 does not need to separately install a gasket for absorbing vibration.
