Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a rotary drum of a clothes dryer for accommodating and rotating and stirring clothes used in general households.

2. Description of the Related Art Conventionally, the rotary drum of this type of clothes dryer has a structure as shown in FIGS. As shown in FIG. 3, a substantially cylindrical rotary drum body 1 has an opening in a part of a curved surface, and a substantially arc-shaped inner lid 2 is arranged in order to use the opening as a clothing inlet. The inner lid 2 can be opened and closed by operating the handle 3. Reference numeral 4 is a substantially arc-shaped guide groove, which guides both side surfaces of the inner lid 2 which are substantially arc-shaped. The cross section of the opening of the rotary drum is as shown in FIG. 4, and four felt materials 5 are attached to the upper and lower sides of the inner lid 2 on both sides. When the inner lid 2 is opened and closed, the felt material 5 and the inner surface of the guide groove 4 having a U-shaped cross section slide. The felt material 5 is used for the sliding surface so that when the clothes are put in the rotary drum body 1 and dried while the inner lid 2 is closed, the hot and humid air inside the rotary drum body is exposed to the outside. This is to prevent leakage.

Problems to be Solved by the Invention In the conventional configuration, in order to prevent the air inside the rotary drum body 1 from leaking out, the felt material 5 and the guide groove 4 are provided.
It is necessary to make the gap with the inner surface of the inner cover 2 as small as possible. If the gap is too small, the operation of opening and closing the inner lid 2 becomes heavy. On the contrary, if this gap is set to be large, the operation of opening and closing the inner lid 2 becomes easy, but there is a problem that the air inside the rotary drum body 1 easily leaks to the outside. Further, when the substantially arcuate shape of both side surfaces of the inner lid 2 does not match the substantially arcuate shape of the inner surface of the guide groove 4, the opening / closing operation of the inner lid 2 becomes heavy, and There was a problem that the air leaked out.

The present invention solves these problems, and the operation of opening and closing the inner lid 2 is easy, and the rotating drum body 1 can be operated during the drying operation.
The purpose is to prevent the air inside from leaking out.

Means for Solving the Problems In order to achieve the above object, the present invention is provided with a charging port formed on a part of a peripheral surface of a rotary drum body and a charging port provided on the charging port so as to be openable and closable along the peripheral surface. A substantially arc-shaped inner lid, and guide grooves for guiding both side surfaces of the inner lid, which are substantially arc-shaped and along the peripheral surface, and the inner lid has side surfaces on the outer peripheral side and the inner peripheral side of the guide groove and a felt. A double structure is formed in which a foam material having elasticity is arranged between the inner lid and the felt material on the outer peripheral side of the inner lid so as to slidably abut.

Action With this configuration, the sliding movement between the inner lid and the guide groove is always performed via the felt material, so that the opening / closing operation can be facilitated. Further, during the drying operation, the inside of the rotary drum is heated and the internal pressure rises, but since the foam material having elastic force is arranged between the felt material and the inner lid on the outer peripheral side of the guide groove, the inner lid is Is pressed against the outer peripheral side surface of the guide groove via the elastic foam material to maintain airtightness, and since the foam material is not pressed at the time of putting on the clothes, opening and closing of the inner lid becomes easy.

Embodiment Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
This will be described with reference to the drawings. FIG. 2 shows the overall structure of a clothes dryer equipped with a rotary drum of the clothes dryer of the present invention. The rotary drum drive unit A is attached from the top of the housing 11. A bottom plate is provided below the rotary drum drive unit A.
There is a motor 12 provided behind the bottom plate 12, and a rotary drum 15 provided on the right side of the motor 13 and the housing 11.
Belts 16 and 17 are respectively stretched between and, and the heat exchange fan 14 and the rotating drum body 15 are rotated by driving the motor 13. Further, the heater 18 is disposed on the left side surface of the housing 11, and a communication pipe 19 that connects the heat exchange fan 14 and the heater 18 is provided on the front side of the housing 11, and a drain port 20 is provided below the communication pipe 19. A tank 22 having a water injection port 21 is provided immediately below the drainage port 20. The tank 22 is removable from the front of the housing 11. Then, due to the rotation of the heat exchange fan 14, the clothes heated by the hot air heated through the heater 18 and agitated in the rotary drum body 15 are heated and dried, and the moisture flows into the tank 22. Rotating drum body
There is an opening in a part of the curved surface of the curved surface 15, and a substantially arc-shaped inner lid 23 is provided to use the opening as a clothing inlet, and the inner lid is operated by operating the handle 24. 23 can be opened and closed. Reference numeral 25 denotes a substantially arc-shaped guide groove, which guides both side surfaces of the inner lid 2 having a substantially arc shape.

FIG. 1 shows a cross section of the opening of the rotary drum. Felt materials 26 are attached to the lower portions of both side surfaces of the inner lid 23. Further, sliding members 27 are attached to the upper portions of both side surfaces of the inner lid 23. This sliding member 27 has a double structure of a foam material 28 having elasticity and a felt material 29, and when opening and closing the inner lid 23,
The felt members 26, 29 slide on the inner surface of the guide groove 25 having a U-shaped cross section. The roles of the felt material 26 and the sliding member 27 are
Firstly, the opening / closing operation of the inner lid 23 is made smooth, and secondly, the moist air in the rotary drum body 15 is not leaked to the outside. Both sides of the inner lid 23 have a substantially arcuate shape and guide grooves
The substantially U-shaped inner surface of the circular arc shape of 25 is basically parallel to each other, but in reality, it is difficult to form completely parallel parts by molding with resin. In the present invention,
With the foam material 28 of the sliding member 27, it is possible to supplement the portions of the inner lid 23 and the guide groove 25 where the substantially arcuate shapes do not match, and to seal the moist air inside the rotary drum body 15. Further, also regarding the operation of opening and closing the inner lid 23, there is an advantage that the foam material 28 serves as a cushioning material and the feel is improved.

As described above, according to the present invention, in particular, the inner lid slidably abuts on the outer peripheral side and the inner peripheral side of the guide groove with the felt material, and at the same time, with the felt material on the outer peripheral side of the inner lid. By forming a double structure in which an elastic foam material is disposed between the inner lid and the inner lid, sliding between the inner lid and the guide groove is always performed through the felt material, so that the opening and closing of the inner lid is prevented. The operation can be facilitated. Further, during the drying operation, the inside of the rotary drum is heated and the internal pressure rises, but since the foam material having elasticity is arranged between the felt material and the inner lid on the outer peripheral side of the guide groove, the inner lid is Is pressed against the outer peripheral side surface of the guide groove via an elastic foam material so that airtightness is maintained and the moist air inside the rotating drum does not leak to the outside, and the foam material is pressed when clothes are put in. Since the inner lid is not present, opening and closing of the inner lid becomes easy.
