Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a drum-type electric dryer for general household use.

Conventional Structure and Problems Conventionally, this type of drum-type electric dryer has a through-hole structure as shown in FIG. The front part of the fuselage 4 partially provided with the baffle plate 3 is a disc 6 which has a flange 5 in the center and has a circular opening, and the rear part of the fuselage 4 is disc-shaped and has a central part. Bearing 7
A drum 9 is housed in which the body plate 4 is fixed by crimping or the like between the circular plate 8 and the outer periphery of the circular plate 8.

At the rear of the drum 9, there is a first fan case 11 to which a shaft lO, which is rotatably supported by a bearing 7, is fixed, and a second fan case 12, which is joined to the fan case 11 of lr1 by caulking or the like. A fan case 13 is formed, with 7 amps inside.
Store 4. A part of the fan case 13 is an open part,
Connect the exhaust pipe 15 to the fan case 13, and connect the exhaust pipe 1 to the fan case 13.
The air after drying is discharged to the outside of the box body 1 via 5.

A bearing 16 is fixed to the second fan case 12 to pivotally support a fan shaft 17.
A fan pulley 18 is fixed in the opposite direction to the 1-in 14.

Reference numeral 19 denotes a motor attached to the bottom of the box body 1 via a bracket 20. The 190 rotations of this motor are caused by a belt 24 wound around a drum pulley 22 and a tension pulley 23 fixed to a motor shaft 21. It is transmitted to the drum 9. At the same time, a fan belt 261C, which is wound between the motor pulley 25 fixed to the motor shaft 21 and the fan pulley 18, is attached to the fan 14.
Rotation is transmitted to.

On the other hand, a bearing material 27 having good wear resistance and a small coefficient of wear is attached and fixed to the inner surface of the flange 5 of the disc 60 at the front of the drum 9 so as to be slidable thereon.

The front portion of the citram 9 is pivotally supported by a front support plate 28 having an outer diameter that is slidable on the inner diameter of the bearing material 27. The front support plate 28 is fixed to the front plate 2 via a block 29 and a heater plate 31 that fixedly supports a heater 30 inside the block 29, and the drum 9 is rotatably supported within the box l. There is.

The front plate 2 also has a window 32 provided in the center of the front support plate 28.
The window 32 and the input port 33 are connected to each other by a backing 34 so as to be airtight. A lid 35 that is rotatably supported by the front plate 2 and a hinge (not shown)
The lid 35 is closed to cover the input port 33, and in this closed state, a lip 36 provided on the lid 35 comes into contact with the backing 34, making the drum 9 airtight.

Further, an air intake port 36' is provided in a part of the lid 35, and an intake port 37 is provided in the front plate 2 at a position opposite to the air intake port 36'.
will be established. At the rear of this suction port 37, a heater plate 31 sandwiched between the front plate 2 and the front support plate 28 and a heater plate 31 are provided.
He fixed it on! I30, and a large number of small holes 38 are provided in the front support plate 28 at a position opposite to the heater 30, so that outside air is communicated to the inside of the drum 9 via the heater 30. While the drum 9 rotates, outside air enters the heater 30 through the air intake port 36'.
The filter cover 39 is heated by the cloth, enters the drum 9, and is removably attached to the circular substrate 8 constituting the drum 9 while exchanging heat with the cloth. and a large number of small holes 41 provided in the circular substrate 8 through which the filter 40, which is detachably attached to the filter cover 39, is passed. Furthermore, the holes 42° in the 71° fan case 13 and the H cylinder 15
The air is exhausted to the outside through the tube, thereby drying the cloth.

By the way, there is currently a strong demand for an electric dryer that can exhaust air in any direction, such as where it is used and how it can be installed. Since the fan case 13 is used to blow air from the exhaust pipe 14 to the exhaust pipe 15, the exhaust direction is largely restricted by the direction of the fan case 13.

It is necessary to provide a gap between the fan case 13 and the like. Therefore, the dimensions of these gaps must also be considered when determining the dimension in the depth direction, which is disadvantageous for thin electric dryers that are small in the depth direction.

OBJECTS OF THE INVENTION It is an object of the present invention to provide an electric dryer that allows the exhaust direction to be freely set and the depth dimension to be reduced.

Structure of the Invention The electric dryer of the present invention comprises: a box body having an opening/closing lid and an exhaust port; a drum rotatably housed within the box body and housing drying materials therein when the lid is opened; and the box body. A partition wall attached to the body circumferential surface and airtightly partitioning a rear space communicating with the exhaust port from the front space, and a fan provided at the rear of the drum and discharging air in the drum to the rear space. It is something that

DESCRIPTION OF THE EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. In FIG. 2, the same constituent members as shown in FIG. 1 are denoted by the same reference numerals (ttL, and the description thereof will be omitted. In FIG. 2, 44 is a partition wall.

This partition wall 44 protrudes inward from the inner peripheral surface of the box body 1, and the seal portion 4 interposed between this partition wall and the outer peripheral surface of the drum 9
5, the rear space 46 of the drum 9 is connected to its front space 4.
It has been airtightly partitioned from 7 onwards.

The seal portion 45 is attached over the entire circumference of the partition wall 44, and the other end is configured to slide against the outer circumferential surface of the drum 9 to maintain an airtight state while not interfering with the rotation button of the drum 9.

In addition, 14 fans are installed at the ridge of the drum 9, and
Filter the air inside (hot air) with cover 39° filter 40
and is discharged into the rear space 46 through the small hole 41 of the circular substrate 8.

Next, to explain the operation of this embodiment, in the rear space 46 which is partitioned from the front space 47 by the partition wall 44 as described above, the 77 cylinder 14 rotates and the air inside the drum 9 is discharged. , internal pressure increases. Therefore, if the exhaust port 48 is provided at an arbitrary position in the rear space 46, the internal air will flow out from there. Therefore, the exhaust port 48
It functions no matter where it is placed on the top, bottom, left or right of the box body 1, and exhaust can be carried out in any direction depending on the position of the exhaust port 48.

Also, the sliding contact of the seal portion 45 with the outer peripheral surface of the drum 9, the second
If the arrangement is as shown in the figure, airtightness can be maintained even if the pressure in the rear space 46 increases.

FIG. 3 shows another embodiment of the present invention, in which the seal portion 45
The sliding contact of ' is brought to the rearmost part of the drum 9.

In this way, the volume of the rear space 460 is small;
Also, since the air does not flow in the forward direction, it is advantageous for the exhaust efficiency to be high.

FIG. 4 shows still another embodiment of the present invention, in which a seal portion 45' is attached to the outer peripheral surface of the drum 9 and is in sliding contact with the partition wall 44 of the box body 1. In this case, only the sliding direction of the seal portion 45' has changed, but there is no change in performance.

Effects of the Invention According to the present invention, the air inside the drum is forcibly discharged to the rear space and the pressure in the rear space is increased.
Exhaust can be performed regardless of the position of the exhaust port, and therefore the exhaust port can be installed in any direction. Furthermore, since there is no fan case gap, the depth dimension can be reduced, making it possible to achieve a thinner design and space saving.
