Description

Dryer {A dryer}

The present invention relates to a dryer for drying clothes, and more particularly, to a dryer capable of supplying hot air from the front and rear sides of a drum.

In general, the clothes drying apparatus is a device that blows dry hot air heated by a heater into an accommodation space in which clothes and the like are accommodated to dry clothes, and is divided into a dryer having only a drying function and a dry washing machine including a washing function.

The dryer lifts the clothes and the like while the drum rotates and drops them, and supplies the drying hot air passing through the heater to the inside of the drum to dry the clothes and the like.

Figure 1 is a schematic configuration diagram showing the air flow inside the dryer according to the prior art, Figure 2 is an exploded perspective view of the dryer according to the prior art, Figure 3 is a partially cutaway perspective view of the dryer according to the prior art.

In the conventional dryer, as shown in FIGS. 1 to 3, a case 2 having a to-be-constructed entry hole 2a formed on a front surface and forming an exterior of the dryer is rotatable inside the case 2. A drum 12 disposed in the front and rear directions so that the dry matter is accommodated therein and air is allowed to pass through, a heater 18 disposed inside the case 2, and drying passed through the heater 18. The hot air guide duct 20 for guiding the dry hot air to the rear of the drum so that the hot air can be discharged forward from the rear side of the drum 12, and the humid air that has been turbid while drying the dried object is outside of the case 2. An exhaust duct 22 to be discharged to the air, a blowing fan 30 provided in the exhaust duct 22, a motor 32 generating a driving force for rotating the blowing fan 30 and the drum 12, and A belt 40 interlocked with a motor 32 to rotate the drum 12. All.

The drum 12 is disposed on the inner circumferential surface is a lift 11 for lifting the object to drop.

The exhaust duct 22 is disposed such that an inlet through which air in the drum is exhausted is disposed at the tip side of the drum and an outlet protrudes out of the case.

On the other hand, the dryer is supported by the rear end of the drum 12 and the rear supporter 14 having a discharge network 15 so that the hot air guided by the hot air guide duct 20 can be discharged to the drum; The front supporter 16 further includes a front supporter 16 rotatably supporting the tip of the drum 12 and having an entry and exit hole 16a formed at a rear portion of the entry and exit hole 2a.

On the other hand, the case (2) is coupled to the cabinet (3) and the front end of the cabinet (3) forming a side of the dryer and the dry entry hole (2a) is formed in the center and the dry entry hole (2a) A cabinet cover 4 having a door 9 for rotatable opening and closing, and an air intake hole 5a coupled to a rear end of the cabinet 3 and into which outside air is sucked, and the exhaust duct ( A back panel 5 having a duct through hole 5b through which 22 is penetrated, a top cover 6 coupled to an upper surface of the cabinet 3 to form an upper surface of a dryer, and a top cover 6 above the top cover 6. It is composed of a combined control panel 7 and a base 8 coupled to the bottom of the cabinet 3 to form the bottom of the dryer and to which the heater 18 and the motor 32 are mounted.

Reference numeral 24 is a filter mounted at the inlet of the exhaust duct 22 to purify the air exhausted from the drum 12.

Looking at the operation of the prior art configured as described above are as follows.

First, after inserting a dry object into the drum 12, closing the door 9 and operating the dryer, the motor 32 is driven to rotate the drum 12 and the blowing fan 30. The heater 18 heats and heats the air therein.

At this time, the dry matter in the drum 12 is lifted by the lift 11 and then dropped.

In addition, the air outside the case 2 is sucked into the air suction hole 5a by the blowing force generated when the blowing fan 30 is rotated, and is heated and dried while passing through the inside of the heater 18. The hot air guide duct 20 and the discharge network 15 is discharged into the drum 12.

The dry hot air supplied into the drum 12 is in direct contact with the falling object to be dried, and then moved to the front end side of the drum 12 to be purified while passing through the filter 24. It is discharged to the outside of the dryer through the exhaust duct (22).

However, in the conventional dryer, since the drying hot air heated by the heater 18 is discharged only at the rear end side of the drum 12, the temperature difference between the front end side and the rear end side of the drum 12 becomes large, and the discharged dry hot air drum (12) Only the dry items on the rear end side may be concentrated to damage the dry matter on the rear end side of the drum 12, and the dry items on the front end side of the drum 12 may take a long time to dry.

On the other hand, if the drying and cooling are repeated by turning on / off the heater 18 in order to prevent damage to the dry items as described above, there is a problem that the drying time of the dry items is long.

The present invention has been made to solve the problems of the prior art, it is an object of the present invention to provide a dryer with high energy efficiency to prevent damage to the dry matter and shorten the drying time.
