BACKGROUND

1. Field

The present invention relates to a clothing dryer. More particularly, the present invention relates to a clothing dryer having a shelf that is detachably installed in a rotating drum.

2. Description of the Related Art

In general, a clothing dryer is an apparatus used to dry clothing by introducing hot air into a rotating drum while rotating the rotating drum accommodating wet clothes at a low speed.

A conventional clothing dryer includes a housing forming an external appearance of the clothing dryer, a rotating drum, which is rotatably installed in the housing and has a cylindrical shape having an open front surface to accommodate clothes therein, a support plate rotatably supporting an open front end of the rotating drum, a driving device for rotating the rotating drum and a drying unit which generates hot air and provides the hot air to the rotating drum.

In addition, since such a clothing dryer performs the drying operation by repeatedly lifting and dropping the clothes according to the operation of the rotating drum, when heavy clothes, such as shoes, are washed, the clothes may be damaged or noise may be generated when the heavy clothes are dropped down.

Accordingly, a shelf that can be horizontally maintained is installed in the rotating drum of the clothing dryer such that the clothes, such as shoes, are dried on the shelf.

However, in the conventional clothing dryer having the above structure, when the shelf is installed in the rotating drum, a front end of the shelf is supported by a support plate, but a rear end of the shelf is not installed in a rear surface of the rotating drum. For this reason, the shelf is installed in the rotating drum in the form of a cantilever in such a manner that only the front end of the shelf is installed in the support plate. In the case that the shelf is installed in the rotating drum in the form of cantilever, the shelf cannot support heavy load, so that heavy clothes cannot be dried on the shelf, and the shelf may be deflected when used for a long period of time.

DETAILED DESCRIPTION OF EMBODIMENTS

Reference will now be made in detail to the embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below to explain the present invention by referring to the figures.

As shown in FIG. 1, a clothing dryer according to an embodiment includes a housing 10 forming an external appearance of the clothing dryer, a rotating drum 20 rotatably installed in the housing 10, a driving unit 30 for generating torque to rotate the rotating drum 20, a drying unit 40 for generating hot air, a condenser (not shown) for condensing moisture contained in the hot air, a cooling unit 50 for providing cool air and a water tank (not shown) for storing water generated from the condenser.

The housing 10 is provided at a front surface thereof with an input opening 11 through which clothes are input into the rotating drum 20. A door 60 is hinged to a front side of the input opening 11 to open/close the input opening 11.

The rotating drum 20 is rotatably installed inside the housing 10. A plurality of lifters 22 are disposed inside the rotating drum 20 in the circumferential direction of the rotating drum 20. The lifters 22 allow the clothes to be lifted and dropped such that the clothes are effectively dried.

The rotating drum 20 is open forward and an open front end of the rotating drum 20 is rotatably installed against a support plate 23. A plurality of communication holes 21a are formed at a rear surface 21 of the rotating drum 20 such that air passes through the communication holes 21a. Accordingly, air heated by the drying unit 40, that is, hot air is introduced to the inside of the rotating drum 20 through the communication holes 21a.

The driving unit 30 includes a motor 31 for generating torque, a pulley 32 rotated by the motor 31 and a belt 33 for connecting the pulley 32 to the rotating drum 20 to transfer power of the motor 31 to the rotating drum 20.

The drying unit 40 heats up air and circulates the heated air to dry the clothes contained in the rotating drum 20. The drying unit 40 includes a heating duct 41 installed at the rear surface 21 of the rotating drum 20 to provide hot air to the rotating drum 20, a heater 42, which is disposed in the heating duct 41 to heat the air passing through the heating duct 41 to generate hot air, a circulation fan 43 allowing the air to be transferred to the rotating drum 20 through the heating duct 41, a hot air discharge duct 44 installed on the support plate 23 to allow air, which has passed through the rotating drum 20, to be discharged, and a hot air circulation passage 45 for guiding the air, which has passed through the condenser, to the heating duct 41.

A filter member 70 is detachably installed on the hot air discharge duct 44 to filter alien substances such as lint. A grip part 71 protrudes from an upper end of the filter member 70 such that the filter member 71 is easily separated from the hot air discharge duct 44.

The cooling unit 50 includes an intake passage 51 for drawing outdoor air through a suction port 12 provided at one side of the housing 10, an exhaust passage 52 allowing air, which has passed through the condenser, to be discharged out of the housing 10, and a cooling fan 53 allowing the air to pass through the intake passage 51, the condenser and the exhaust passage 52.

Although not shown in the drawings, the condenser is disposed between the hot air discharge duct 44 and the hot air circulation passage 45, and between the intake passage 51 and the exhaust passage 52 such that hot air, which circulates from the hot air discharge duct 44 to the hot air circulation passage 45, is cooled by the air circulating from the intake passage 51 to the exhaust passage 52, thereby condensing moisture contained in the hot air.

In addition, according to the clothing dryer of the present embodiment, as shown in FIGS. 2 and 3, a shelf 80 is detachably installed in the rotating drum 20 to dry the clothes such as shoes. A front end of the shelf 80 is supported by the support plate 23, and a rear end of the shelf 80 is supported by the rear surface 21 of the rotating drum 20 through a support member 90. The support member 90 is installed on the rear surface 21 of the rotating drum 20 and has a center of rotation positioned on the rear end of the shelf 80 such that the rear end of the shelf 80 is supported by the rear surface 21 of the rotating drum 20. Accordingly, since the front end and the rear end of the shelf 80 are supported, even if heavy clothes are loaded on the shelf 80, the shelf 80 stably supports the clothes.

Since the hot air discharge duct 44 is provided below the support plate 23 and the filter member 70 is installed on the hot air discharge duct 44, the front end of the shelf 80 is supported by the support plate 23 through the filter member 70. An insertion groove 82a, into which a grip part 71 is inserted, is recessed at a front lower part of the shelf 80 such that the front end of the shelf 80 is stably installed on the filter member 70. The shelf 80 includes a shelf part 81 and a support part 82. The clothes are loaded on the shelf part 61 having a through-hole 81a allowing air to pass therethrough. The support part 82 is provided at a front end of the shelf part 81 and has the insertion groove 82a formed at a lower surface thereof such that the support part is supported by the filter member 70.

As shown in FIG. 4, the support member 90 includes a hinge part 91, which is rotatably installed on the rear end of the shelf 80 while forming the center of rotation of the support member 90 and a plurality of legs 92 radially extending about the hinge part 91 to be supported by the rear surface 21 of the rotating drum 20. An insertion part 93 is provided at each end of the legs part 92 and is inserted into one of the communication holes 21a. The support member 90 includes three leg parts 92 and is provided in the form of a tripod.

In addition, a hinge hole 83a is formed in the rear end of the shelf 80 such that the hinge part 91 is rotatably installed in the hinge hole 83a. A hinge installation part 83 is installed at the rear end of the shelf 80 and includes material having abrasion resistance superior to that of material forming the shelf 80 such that the hinge hole 83a is provided on the hinge installation part 83. Accordingly, the friction is prevented from being generated between the hinge part 91 and the hinge hole 83a when the support member 90 rotates. In addition, the hinge hole 83a is prevented from becoming larger due to the abrasion of the hinge part 91 and the hinge hole 83a caused by the friction.

Accordingly, if the hinge part 91 of the support member 90 is installed in the hinge hole 83a of the shelf 80 such that the insertion part 93 is inserted into the communication hole 21a of the rear surface 21 of the rotating drum 20, the support member 90 rotates together with the rotating drum 20. Even if the support member 90 rotates, the hinge part 91 formed on the center of rotation of the support member 90 keeps a constant position, so that the rear end of the shelf 80 is supported by the support member 90. Accordingly, the front end of the shelf 80 is supported by the support plate 23 through the filter member 70, and the rear end of the shelf 80 is supported by the rear surface 21 of the rotating drum 20 through the support member 90, so that the shelf 80 is stably supported in the rotating drum 20.

Although the present embodiment has been described in that the hinge installation part 83 having the hinge hole 83a is installed on the rear end of the shelf 80 as a separate member, the present invention is not limited thereto. According to another embodiment, the hinge hole 83a may be directly formed in the rear end of the shelf 80.

Although few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and sprit of the invention, the scope of which is defined in the claims and their equivalents.
