Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a clothes dryer having a rotating drum that automatically rotates forward and reverse.

Conventionally, dryers dry clothes by supplying hot air and passing the clothes through. A buttful is provided on the inner wall of the rotating drum, and after the clothes are carried above the rotating drum, the clothes are moved to the bottom center of the drum. The drying efficiency is increased by rotating the clothes and increasing contact with the hot air. Recently, when rotating a rotating drum in one direction, drying efficiency has been improved by tilting the mounting position of the buttful with respect to the rotating direction of the rotating drum. was unsatisfactory in use due to a significant drop in drying efficiency during reversal.

This invention was developed with the above points in mind.
It is an object of the present invention to provide a forward/reverse type clothes dryer which always has good drying efficiency by configuring a baffle to be rotatable with respect to a rotating drum.

An embodiment of the present invention will be described below with reference to the drawings.

Reference numeral 1 denotes an outer box, and a door 2 equipped with a handle is pivotally installed in a circular opening in the center of the front surface for taking in and taking out dried materials so as to be openable and closable. 3 has multiple Batsuful 4 inside
A rotating drum with a front end plate 3a having a short cylindrical circular flange 3b supported by a bearing 5 attached to a flange 1a formed on the outer box 1, and a rear end supported by a bearing 5 attached to a flange 1a formed on the outer box 1. A rotary shaft 6 fixed to the center of the rear end plate 3c is supported by a bearing 8 fixed to the center of the air expansion plate 7 fixed to the outer box 1. Further, the rear end plate 3c has a large number of ventilation holes (not shown) facing the air expansion plate 7. As shown in FIG. 2, a hole 3e is formed in the side plate 3d of the rotating drum 3 with a dimension a deviating from the center toward the rear end plate 3c. On the opposite side of the hole 3e, that is, near the end of the front end plate 3a, protrusions 3f and 3g for locking the buttful 4 are formed at symmetrical positions on a circular locus centered on the hole 3e. The baffle 4 has a substantially trapezoidal cross section with a long bottom and a short top in the front-rear direction, has a depth substantially equal to the depth of the rotating drum 3, and is in contact with the side plate 3d of the rotating drum 3 at the bottom. and hole 3e
It has a rotating shaft 9 corresponding to. The baffle 4 is rotatably attached to the rotating drum 3 about this rotating shaft 9. Further, at the tip of the rotating shaft 9, an elastic claw 10 is formed as a locking part, which has a conical claw part 10a whose root part has a larger diameter than the rotating shaft 9 and whose tip has a smaller diameter, and a split part 10b in the center. ing. The spacing between the protrusions 3f and 3g of the rotary drum 3 is set so that the angle of inclination between the baffle 4 and the rotary drum 3 is optimized. A motor 11 is fixed to the lower part of the outer box 1, and a belt 14 is attached to the outer periphery of the side plate 3d of the rotating drum 3 via a pulley 12 and an idle pulley 13 that are directly connected to the shaft of the motor 11. 15 is a fan directly connected to the shaft of the motor 11, 16 is a heater, and 17 is a casing.

Next, the operation of the above configuration will be explained.

First, to explain how to attach the buttful 4, place the buttfull 4 at right angles to the rear end plate 3c of the rotary drum 3, align the rotating shaft 9 with the hole 3e, and forcefully press the elastic claw 10 into the hole 3e. Then, the elastic claw 10 contracts between the slotted portions 10b, and the conical portion 10a closes in the hole 3e.
The conical portion 10a is restored and can be rotated between the rotating shaft 9 and the hole 3e, and since the root diameter of the conical portion 10a is larger than that of the hole 3e, there is no risk of it falling off easily in normal use. Further, when removing the baffle 4, the slotted portion 10b contracts and can be removed by pulling it out forcefully using the reverse method described above.

Next, when the rotary drum 3 rotates in the direction of arrow B, the material to be dried is loaded on the right side of the buffle 4 shown in FIG. 2, and the baffle 4 is subjected to a force on the left side in the figure over its entire surface by the material to be dried. Then Batsuful 4
The center of rotation is on the rotating shaft 9, which is offset by a dimension from the center of the rotating drum 3, so the buttful 4 rotates clockwise in the figure, and its end surface contacts the protrusion 3g of the rotating drum 3, causing its inclination. Angle C is determined. Further, when the rotary drum 3 rotates in the opposite direction of arrow B, the direction of rotation is opposite to that described above, and the baffle 4 rotates with an inclination angle D.

According to the above embodiment, the mounting angle of the rotary drum 3 and the buttful 4 can always be set at an angle that provides the highest efficiency regardless of the rotation direction of the rotary drum 3, and the same performance can be maintained even during forward and reverse rotation. There is an effect that can be done.

Note that the present invention is not limited to the above embodiments, and various modifications are possible.

As described above, the present invention has a baffle on the inner wall of the rotary drum at a position that is biased towards the end plate from the center and is rotatable with respect to the rotary drum. A clothes dryer with drying efficiency can be provided.
