BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a futon dryer and a futon drying method which can dry a futon containing water after washing to a state where it is swollen.

[0002]

2. Description of the Related Art Clothes dryers are used to dry quilted products such as kotatsu futons and blankets, etc., which do not lose their shape, because the basket does not get caught when the basket rotates forward and backward. it can. But,
With a normal comforter or mattress, containing water after washing,
When trying to dry with this clothes dryer, the futon repeats violently forward and reverse in the basket,
There is a problem that twisting or offsetting occurs, and furthermore, binding of the stitches and tearing of the cloth occur.

[0003] Therefore, conventionally, in order to dry the futon,
As shown in FIG. 6, a stationary dryer that puts the futon F on a stationary table 9 in a stationary state and supplies hot air has been considered. However, in this still dryer, since the futon F is dried in a still state, it cannot be restored to a state having a plump bulge. Therefore, the futon F that has been dried by the stationary dryer is replaced with a dryer for another garment and the swelling is provided by repeating normal rotation and reverse rotation. The dried futon F is different from the futon F in a state of containing water, and does not cause problems such as cutting, twisting, and offsetting of the cotton even when the futon F is rotated forward and backward.

According to this, since it is necessary to transfer the futon F from the still dryer to another dryer for clothes, there is a problem that the operation is troublesome and troublesome.

[0005] On the other hand, as shown in FIG. 7, there is a type in which the futon F is restored to its bulge by normal rotation and reverse rotation without drying the dryer. This automatic reversing dryer is provided with a partition 10 in a basket,
To prevent the cotton from being cut or lean.

[0006]

However, in this automatic reversing drier, since the basket 10 is provided with the partition 10, the occurrence of cotton breakage is small, but the forward and reverse rotation of the futon F is insufficient. . Therefore, there is a problem that the restoration effect for giving the futon F a sufficient swelling is small.

Therefore, it is an object of the present invention to be able to dry the futon F containing water after washing by one unit and to restore the futon F to a state having a plump bulge. An object of the present invention is to provide a futon dryer and a futon drying method.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A futon dryer according to an embodiment of the present invention will be described with reference to FIGS. FIG.
Is a schematic perspective view showing a futon dryer, and FIG. 2 is a schematic perspective view showing the basket 1.

The futon dryer according to the embodiment of the present invention is rotatable in both the forward and reverse directions, has a circumferential length larger than the length of the futon F, and is provided on the rear surface of the cylindrical wall 2 in which a number of punching holes 6 are formed. A futon F containing water after washing is put into a drum-shaped basket 1 provided with a rear wall 3, and the basket 1 is rotated. Hot air W is supplied from the rear wall 3 side of the basket 1 to provide a futon. F is to be dried. The front surface of the basket 1 is closed by a front door 7 that can be freely opened and closed.

In this futon dryer, the basket 1
A rib 4 is provided on the inner surface of the cylindrical wall 2 to abut on the front end of the futon F in the front-rear direction. In addition, a pipe 5 projects from the rear wall 3 in parallel with the rib 4 and on the side opposite to the rib 4 in the reverse rotation direction.

The distance L between the pipe 5 and the cylindrical wall 2 is
Is set to about 90 mm, which is slightly larger than the thickness (about 70 mm), and the interval M between the pipe 5 and the rib 4 is set to about 140 mm. This interval of about 140 mm is
However, when a sufficient centrifugal force has not been received at the initial stage of rotation of the basket 1, the tip of the
滑 り 40 mm after sliding off and falling off, the length required to catch and prevent falling from below, and rotate the basket 1 in both forward and reverse directions to remove the vicinity of the tip of the futon F It is of a suitable length to be easily released from the support by the cylindrical wall 2 and the pipe 5.

Drying of the futon F using the futon dryer is performed in the order of a drying step, an opening step and a tapping step. The drying process is as follows. First, washing is completed,
A futon F containing water is put into the basket 1 along the cylindrical wall 2, and the tip of the futon F is abutted against the rib 4 of the basket 1, and the vicinity of the tip is connected to the cylindrical wall 2 and the pipe 5. Then, the front door 7 is closed and the switch is turned on. As a result, the basket 1 rotates in the forward direction (clockwise) and the basket 1 rotates.
Hot air W is supplied from the rear wall 3 (see FIG. 3A).
Due to the centrifugal force of the rotation of the basket 1, the futon F
Also rotates at the same time. At this time, since the vicinity of the front end of the futon F is supported by the cylindrical wall 2 and the pipe 5, it does not fall by its own weight.

The hot air W supplied from the rear wall 3 passes through the futon F and is discharged out of the punching holes 6 together with the moisture of the futon F, so that the futon F is dried. The temperature of the hot air W is about 80 degrees, the basket 1 is rotated 60 times per minute, and the drying time is about 50 minutes. by this,
The futon F can be reliably dried.

After the drying of the futon F, the opening process is started.
In the opening step, the supply of the hot air W is stopped, and the basket 1 is rotated alternately in both forward and reverse directions. By this, Futon F
Is released from the support by the basket 1 cylindrical wall 2 and the pipe 5 (see FIG. 3B). At this time, the rotation speed of the basket 1 is 35 rotations per minute, and the rotation time is 1 rotation.
Minutes.

A tapping step is performed following the opening step. In the tapping process, the hot air W is supplied again into the basket 1 while the basket 1 continues to rotate in both the forward and reverse directions. As a result, the so-called tapping effect that the futon F in the free state is lifted by the centrifugal force of the basket 1 and then dropped by its own weight is given (FIG. 3C).
reference). Due to this tapping effect, the futon F is restored to a plump state. At this time, it is more effectively restored by the action of the hot air W. At this time, the rotation speed of the basket 1 is 35 rotations per minute, and the rotation time is about 5 minutes.

Note that a cooling step can be added following the tapping step. In this cooling step, with the supply of the hot air W stopped, the basket 1 is continuously rotated alternately in both the forward and reverse directions to gradually cool the futon F to normal temperature. The rotation speed of the basket 1 at this time is suitably 35 rotations per minute.

In the futon dryer according to the present embodiment, since the circumference of the cylindrical wall 2 of the basket 1 is larger than the length of the futon F to be dried, an empty portion of the cylindrical wall 2 where the futon F does not contact (about 1% of the circumference). / 4) is closed by a heat-resistant closing sheet 8. By doing so, all of the hot air W can pass through the futon F to reach the punching holes 6, so that the drying efficiency can be improved.

The difference in the drying time between the case where the closing sheet 8 was provided and the case where the closing sheet 8 was not provided was confirmed by an experiment using a quilt made of cotton. The result is shown in FIG.
Shown in Is a case where the closing sheet 8 is provided to close the punching hole 6 in the empty portion, and is a case where is not closed.
From this experiment, it can be seen that in order to dry the futon 100%, 120 minutes are required when the punching hole 6 is not closed, whereas 50 minutes is sufficient when the punching hole 6 is closed. Here, the punching hole 6 in the portion of the cylindrical wall 2 where the futon F does not contact is closed by the closing sheet 8.
A structure in which the punching holes 6 are not provided in advance in a portion where the futon F does not hit may be obtained. According to this, the same result (50 minutes is required for 100% drying) was obtained.

The pipe 5 of the basket 1 can be fixed to the rear wall 3 or can be detachable. If the pipe 5 is made detachable, it is removed when giving a beating effect to the futon F or when drying the clothes or the like with this futon dryer, so that the harmful effects such as the clothes being caught on the pipe 5 and becoming difficult to dry are surely prevented. Can be prevented.

The distance between the rear end of the pipe 5 and the cylindrical wall 2 of the basket 1 can be freely set, and can be set wider than the distance between the front end of the pipe 5 and the cylindrical wall 2 (FIG. 5).
reference). By doing so, when the width of the futon F is wider than the front-rear width of the basket 1, the futon F is put into the basket 1 in a state where the side ends are folded, and the folded portion P having the increased wall thickness is piped. 5 and the cylindrical wall 2 of the basket 1 can be inserted. Therefore,
A wide futon F can be accommodated.
