4, they are joined to be airtight. 36 is front plate 1
A lid 35 is rotatably supported by a hinge (not shown) on b, and the lid 35 is closed so as to cover the inlet port 33, and by this closing, the lip 3 provided on the lid 35 is opened and closed.
6 abuts against the backing 34 to make the drum 2 airtight.

Further, an air intake port 36 is provided in a part of the lid 36, and an inlet port 37 is provided in the front plate 1b at a position facing the air intake port 36. At the rear of this intake port 37,
There is a heater plate 31 sandwiched between the front plate 2 and the front support plate 28, and a heater 3o fixed to the heater plate 31, and a large number of small holes are provided in the position of the front support plate 28 facing the heater 3o. 38 is provided, and outside air entering through the heater 30 is introduced into the inside of the drum 2 through the small hole 38.

In the conventional configuration as described above, by rotating the drum 2, the outside air that enters from the air intake port 36 is heated by the heater 3o and enters the drum 2, and while exchanging heat with the cloth, the outside air enters the drum 2. A large number of small holes 41 provided in the circular substrate 8 and holes 42 provided in the fan case A11 pass through a filter cover 39 detachably attached to the substrate 8 and a filter 40 detachably attached to the filter cover 39. The cloth is dried by exhausting the air through the fan case 13 and the exhaust pipe 15 to the outside.

However, in the above conventional configuration, the front support plate 28
In addition, since the heater plate 31 that fixedly supports the heater 3o is fixed, the front support plate 28 is hot during drying or even when drying is finished, so hands, arms, etc. is the input port 33 of the front support plate 28
The backing 34 is made of one kind of flexible material,
The end of the window 32 of the front support plate 28 and the input port 33 of the front plate 1b
The seal part 44 that keeps the end of the lid airtight and the lip part 43 that keeps the gap between the lid 35 and the front plate 1b airtight are brought into contact using their elasticity to maintain airtightness. The lip 36 of the lid 35 and the edges of the window 32 and the slot 33, which are kept in contact for a long time, are not particularly finished to make them flat, so the sealing part 44 and the lip part 43
Airtightness cannot be maintained unless the lip 36 and window 32 contact the end of the input port 33 over the entire circumference, so a material with a soft hardness is required. However, in order to fix the backing 34 to the front plate 1b, the unfolded length of the banking 34 is set longer than the circumference of the input port 33 of the front plate 2, and the backing 34 is attached to the front plate 1b. In this case, the installation cannot be done reliably and it is necessary to use adhesive or other means to fix it.

As described above, in the conventional configuration, there is a risk of low-temperature burns caused by touching the hot part of the front support plate 28, and there are also problems in that fixing means such as adhesive is required when attaching the window backing. there were.

A clothes dryer that improves safety and airtightness by improving the backing that seals between the holding plate and the front plate, improves the fixing force for attaching to the front plate, and prevents part of the cover from turning up. The purpose is to provide the following.

Structure of the Invention In order to achieve the above object, the present invention includes: a knob portion located on the lid side of a backing attached to an inlet portion of a front plate; a seal portion located between the front plate and the front support plate; A portion of the cover extending to the vicinity of the inner circumferential end of the input port of the front support plate is integrally made of a flexible material, and only the lip portion and the end of the seal portion are made of a soft material. According to this configuration, the airtightness between the lid and the front plate and the airtightness between the front plate and the front support plate can be ensured by contacting the soft part of the backing, and the heat of the heater can be ensured. Since the inner circumferential surface of the input opening of the front support plate, which gets hot due to heat, is covered with a cover, there is no risk of hands or arms coming into direct contact with the front support plate when loading or unloading clothes, thereby improving the safety of the user. In addition, since the attachment part of the backing to the front plate and a part of the cover are hard, it is possible to increase the attachment fixing force to the front plate, and to remove the cloth from the drum. It is also possible to prevent part of the cover from turning over when putting it in and taking it out.

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. Note that in FIG. 2, the same parts as in FIG. 1 showing the conventional example are given the same numbers, and therefore only the points that are different from the conventional example will be explained. That is, in one embodiment of the present invention, the backing 34 that seals between the front support plate 28 and the front plate 1b is improved.
As shown in FIG. 2, a lip portion 43 located on the lid 36 side of the backing 34 attached to the input port 33 of the front plate 1b, and a seal portion 4 located between the front plate 1b and the front support plate 28.
4 and a cover portion 46 extending to the vicinity of the inner peripheral surface end of the input port 33 of the front plate 1b are integrally formed of a flexible material, and the lip 43 and the end of the seal portion 44 are integrally formed. It is made of a softer material. With such a configuration, when the lid 36 is closed, the rib 36 comes into contact with the hard, soft lip portion 43, making the inside of the drum 2 airtight. Also, a soft seal portion 44 provided on the backing 34 between the end of the front plate 1b and the end of the front support plate 28 abuts against the end of the front support plate 28 to provide airtightness. Furthermore, a backing 34 is extended from this seal portion 44 at a corner near the inner peripheral surface end of the input port 33 of the front support plate 28, and the backing 34 is extended from the seal portion 44 to
A constricted portion 46 that is thinner than other portions is formed at a portion located at the end of the front plate 2, which is the base of a cover portion 45 formed to cover the inner circumferential surface of the front plate 8.

The backing 34 in the above configuration has an airtight sealing function between the lid 35 and the front plate 1b, and an airtight sealing function between the front plate 1b and the front support plate 28, and is made of a soft material to ensure that it conforms to the contact surface. As a result, airtightness within the drum 2 can be maintained reliably, and the cover portion 45 extending to the vicinity of the inner circumferential surface end of the input port 33 of the front support plate 28 prevents the occurrence of air leakage in the heater 31. Since the inner periphery of the input port 33 in the front support plate 28, which gets hot due to heat, is covered, the user's hands or arms are prevented from directly touching the front support plate 28 when putting in and taking out clothes. It is something that can be prevented. Moreover, since the hardness of the cover part 45 is made hard, it is possible to prevent the cover part 45 from turning over when taking out clothes from inside the drum 2. Further, the constricted portion 46 is
When the front support plate 28 is attached to the backing 34 attached to the front plate 1b and the single-shaped seal portion 44 is pushed in to form an airtight seal, the force of the backing 34 and the loop portion 46 are transferred to the front support plate 2.
The cover part 46 has a shape that follows the inner circumferential surface of the front support plate 28 .

Also, when attaching the notch 34 to the front plate 1b, the notch 34 is attached to the lip portion 43 and the seal portion 44.
□Since the hardness is increased other than □, the fixing force of the installation can be increased.

Effects of the Invention As described above, according to the present invention, the lug portion located on the lid side of the backing attached to the input port of the front plate, the seal portion located between the front plate and the front support plate, and the front A portion of the cover extending to the vicinity of the inner circumferential end of the inlet portion of the support plate is integrally formed of a flexible material, and only the lip portion and the end of the seal portion are made of a soft material. As a result, airtightness between the lid and the front plate and between the front plate and the front support plate can be ensured by contacting the soft part of the knob, and also by the heat of the heater. The inner circumferential surface of the input opening of the front support plate, which gets hot, is covered with a heathered cover, eliminating the risk of hands or arms coming into direct contact with the front support plate when loading and unloading clothes.As a result, the user's safety is improved. It is possible to improve sexual performance. Moreover, since the attachment part of the backing to the front plate and a part of the cover are hardened, it is possible to increase the attachment fixing force to the front plate, and also prevent part of the cover from turning over when cloth is taken in and out of the drum. It is also something that can be prevented.
