Description

Sealing structure of dryer opening {Sealing assembly of door part for clothes dryer}

The present invention relates to a dryer for drying laundry after washing, and more particularly, to an inlet sealing structure of a dryer for preventing hot air and wet steam from leaking to an inlet side.

In general, the dryer is composed of a case constituting the external appearance of the apparatus, a drying unit provided inside the case, and a piping unit for supplying hot air to the drying unit and discharging wet steam. In this case, the case includes a center cabinet 11 forming a body of the apparatus, a base cover 12 installed below the center cabinet 11, and an operation unit 13 ′ installed above the center cabinet 11. The formed top cover 13, the front frame 14 installed in the front of the center cabinet 11, the door frame 15 is provided in the inlet portion, and the back frame 16 provided in the rear of the center cabinet 11 ) Here, the door glass 15 'is provided with a door glass 15' so as to grasp the state of the drying unit.

The drying unit is installed between the drum 20 and the front frame 14 and the drum 20 are installed inside the center cabinet 11, the lifter 21 is rotated to lift the laundry therein, A front support 22 supporting the front of the drum 20 and a rear support 23 provided between the back frame 16 and the drum 20 to support the rear of the drum 20. It is.

The piping unit may include a heater 31 for generating hot air, a hot air supply duct 32 installed at the rear support 23 and supplying hot air generated from the heater 31 to the rear of the drum 20; An exhaust duct 34 installed at the front support 14 to discharge wet steam to the outside of the apparatus, a fan 33 installed at one side of the exhaust duct 34 and driven by a motor 33 ', and the It is comprised by the filter 34 'provided in the front support 14, and inserted in the said exhaust duct 34. As shown in FIG.

Open the door frame 15 of the dryer and put the laundry inside the drum (20). Thereafter, when the dryer is operated, the drum 20 is slowly rotated, and thus the lifter 21 is also rotated, thereby repeating the process of lifting and dropping the laundry. At this time, since the hot air generated by the heater 31 is supplied into the drum 20 through the hot air supply duct 32, the moisture in the laundry is evaporated by the hot air to dry the laundry.

The wet steam generated during the drying of the laundry is discharged to the outside through the exhaust duct 34 as the fan 33 installed in the exhaust duct 34 is driven. At this time, the filter 34 ′ installed in the front supporter 14 filters the foreign matter contained in the wet steam so that the fan 33 is not broken by the foreign matter.

However, since the wet steam is discharged through the exhaust duct 34 connected to the front support 14, the wet steam tends to be temporarily collected at the inlet of the dryer. Therefore, there exists a possibility that hot air or wet steam may leak through the clearance gap between each component which forms the inlet part of a dryer. In other words, when the airtightness of the front support portion 14 is incomplete, hot air or wet steam leaks through the inlet side through which laundry is introduced, causing user dissatisfaction. Therefore, the sealing structure is installed in the inlet portion into which the laundry is introduced so as not to leak hot air or wet steam.

Conventional dryer inlet sealing structure is installed in Figures 2 and 3, Figure 2 is a cross-sectional view showing the inlet portion of the dryer, Figure 3 is an enlarged view showing the sealing structure of the inlet portion.

That is, the part where hot air or wet steam leaks from the inlet part of the dryer is between the door frame 15 and the door glass 15 ', between the front frame 14 and the door frame 15, the front frame 15 and the front support. Since it is a clearance gap formed between 22, sealing 41, 42, 43 is provided in these parts, respectively, and hot air and wet steam do not leak.

However, the inlet sealing structure of the conventional dryer has a problem in that the assembly is complicated and the labor cost is increased because the different sealing is installed for each of the three leakage sites.

The present invention has been made to solve the above problems of the prior art, by changing the configuration of the sealing member to seal the leakage portion of the inlet portion of the dryer by airtight so as to simplify the structure and reduce the assembly cost The purpose is to provide an inlet sealing structure of the dryer.
