Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a drying device for bedding such as futons that efficiently dries a large amount of bedding such as futons.

[Conventional technology] When forcibly drying futons, etc. after washing,
Conventionally, a method has been adopted in which one or two round rods are arranged in a drying room, a futon is hung on the rods, and hot air is blown onto the futon to dry it.

However, in the drying apparatus according to the conventional example described above, there are problems in that after drying, a dent is formed in the part where the round bar comes into contact, or the lower ends of the futon are sagged and lose their shape. For this purpose, thread binding is applied at appropriate locations, but this is insufficient to prevent deformation and loosening.

Furthermore, there was a problem in that the drying time was different between the upper and lower parts, making it difficult to dry them uniformly in a short period of time.

On the other hand, as described in Japanese Utility Model Publication No. 51-103768, a bedding dryer has been proposed in which a frame for holding bedding is placed in a drying chamber for drying using a plurality of linear moving conveyors.

[Problem that the invention seeks to solve]

However, in the bedding dryer described in the above-mentioned Japanese Utility Model Publication No. 51-103768, the loading frame is rectangular and the drying chamber is also box-shaped, so when bedding is placed on the entire loading frame and the moving conveyor, There are no gaps for hot air to pass through, so it is necessary to place bedding at appropriate intervals, and depending on how well the bedding is placed, dry patches may occur.

Further, no consideration is given to the treatment of the hot air generated by the heater, and there is also the problem that the hot air leaks from the drying chamber and comes out to the outside, worsening the working environment.

The present invention has been developed in view of these circumstances, and it does not easily lose its shape or loosen during drying, and can evenly dry a large amount of bedding such as futons in a short time without drying spots, which also worsens the working environment. The purpose of the present invention is to provide a drying device for bedding such as futons.

[Means to solve problems]

A drying device for bedding such as futons according to the present invention, which achieves the above object, stores bedding such as futons in a drying shelf body placed on a disc-shaped turntable, which can be pulled out freely and at predetermined intervals in the vertical direction. A flat rectangular drying net rack on which the drying products are placed, an air intake with a blower that spreads vertically on one side, and an air outlet with a blower that spreads vertically on the other side. A futon, etc., which has a cylindrical drying chamber provided with an entrance/exit with a door that can be opened/closed on the other side, and with a small gap between the periphery of the turntable and the upper end of the drying rack body. In the bedding drying device, the drying rack main body is disposed to extend to the circumference of the turntable, and the width of the entrance is wider than the net shelf, so that each of the net shelves protrudes from the drying chamber and can be pulled out. Moreover, the capacity of the blower installed at the air outlet is larger than that of the blower inside the drying chamber installed at the air intake, creating a negative pressure inside the drying chamber, and the heater is installed after the blower on the air intake side. It is composed of

[Effect]

The apparatus for drying bedding such as futons according to the present invention includes a turntable disposed inside a drying room having a door that can be opened and closed, and a plurality of net shelves on which bedding such as futons are placed on the turntable. . Therefore,
During the process of being dried by air heated by a heater from the air intake port, bedding such as futons are placed on mesh shelves arranged at predetermined intervals with gaps and rotated in the drying chamber. Therefore, warm air can evenly pass through bedding such as futons, allowing for even drying in the minimum amount of time. In addition, there are a plurality of net shelves on which futons are placed, which are shaped like drawers, and the width of the entrance is wider than the net shelves, so that the net shelves can be pulled out from the drying room and bedding such as futons can be easily placed thereon.

In particular, the net shelf on which the bedding is placed has a rectangular plane, the drying chamber has a circular cross section, and the drying shelf itself extends to the circumference of the turntable.
Since the drying chamber has a small gap between the periphery of the turntable and the upper end of the drying rack body, the space formed between the circular cross section of the drying chamber and the rectangular plane of the net rack is an effective path for hot air. Since the hot air flows through the gaps between the net shelves, even if all the net shelves are loaded with bedding, the hot air passes horizontally between the net shelves, allowing a large amount of bedding to be dried at the same time.

Furthermore, since the blower at the air outlet has a larger capacity than the blower at the air intake, the interior of the drying chamber becomes negative pressure and hot air containing a large amount of steam does not leak outside.

〔Example〕

Next, with reference to the attached drawings, a cleaning equipment for bedding such as a futon that employs a drying device for bedding such as a futon according to an embodiment of the present invention will be explained to provide an understanding of the present invention.

Here, FIG. 1 is a plan sectional view of a drying apparatus for bedding such as a futon according to an embodiment of the present invention, and FIG. 2 is a sectional view of the drying apparatus for bedding such as a futon.

and blowers 16 and 17 attached to the air outlet 15, respectively, and a heater 18 attached in front of the air intake 14.
These will be explained in detail below.

As shown in FIG. 1, the drying chamber 11 has a cylindrical cross section, and an entrance 19 is formed on the side of the drying chamber 11 through which bedding such as futons can be put in and taken out. As an example, a double-opening arc-shaped sliding door 20 is attached to slide on the side surface of the drying chamber 11. The size of the entrance/exit 19 is such that when the turntable 12 is rotated to a predetermined position, the drawer-shaped net shelf 13 will pop out from the entrance/exit 19, allowing futons, etc. to be taken in and out from the outside of the drying chamber 11. size has been determined.

The air intake port 1 is located opposite to the inlet/outlet port 19.
4 and an air outlet 15 are provided, and the air intake 14 and air outlet 15 form a vertically elongated rectangle that spreads vertically.
Warm air is evenly distributed from the top to the bottom of 1. Note that depending on the shape of the duct or the type of bedding that is the target object, it is also possible to provide a rectifying plate made of a plurality of plate materials to control the flow of warm air, if necessary.

A blower 16 is provided at the air intake port 14, and a heater 18 is provided at the rear of the blower 16 to heat the air taken into the drying chamber 11 by the blower 16 to about 60 to 80 degrees Celsius. It has a structure.

On the other hand, a blower 17 is also provided at the air outlet 15;
The drying chamber 11 is set to a negative pressure of about 1.5 to 2 times that of the drying chamber 11 to prevent hot air from leaking from inside, and the air outlet 15 is provided with a damper 17a so that the temperature and air volume can be controlled. It's becoming like that.

A turntable 12 is disposed in the drying chamber 11 with a small gap around the periphery.A sprocket 21 is attached to the center of the turntable 12, and a deceleration motor 2 is connected to the turntable 12 by a chain 22.
Sprocket 24 attached to the output shaft of No. 3
The turntable 12 is rotated at a speed of 1 to 2 rpm by the rotation of the deceleration motor 23.

A guide roller 26 is attached to the lower periphery of the turntable 12 and rotates on a lower guide rail 26a, thereby reinforcing the periphery of the turntable 12.

A drying shelf main body 27 having a small gap with the ceiling of the drying chamber 11 is disposed above the turntable 12, and the drying shelf main body 27 has 20 mesh shelves 13 for drying that can be freely pulled out and arranged in 10 stages. The net shelves 13 are placed with gaps that allow sufficient air to enter between the individual net shelves 13. This mesh shelf 13 is made by attaching a welded wire mesh (wire diameter 1.63, 2 mesh) to the top surface of the pipe frame, and can be freely pulled out from the drying shelf main body 27 and protrudes from the entrance 19, so that the futon 28 can be carried from outside the drying room 11. It can be placed on a net shelf 13.

When using this drying device 10 for bedding such as futons, open the doorway, pull out the net shelf 13, place the futon 28, which is an example of bedding, on it, close the sliding door 20, and turn the turntable 12 at about 1 rpm.

As a result, the net shelves 13 are arranged at predetermined intervals with gaps and are rotated, so that warm air is discharged from the space formed by the drying shelf main body 27, the net shelves 13, and the inner wall of the drying chamber 11. Since the futon is heated and dried evenly through the gaps between the mesh racks, the futon is dried evenly and in a short time. The moisture content will be less than 15%.

Moreover, in this case, the futon is arranged in a flat state,
Since the futon is dried on a rack, it won't wrinkle when drying, and the futon is dried on a net rack.
The cotton will not be torn or unevenly distributed due to drying.

〔Effect of the invention〕

As is clear from the above description, the apparatus for drying bedding such as futons according to the present invention uses a plurality of net shelves arranged with gaps at predetermined intervals, and dries the bedding with warm air. , a large amount of bedding such as futons can be dried regardless of the weather.

Since the bedding to be dried, such as a futon, can be laid out on the net rack, it is less likely to lose its shape or loosen during drying.

In particular, in the present invention, the net rack has a rectangular planar shape, and the drying chamber has a cylindrical shape that is slightly larger than the outer shape of the drying rack main body on which the net rack is placed, and the effective rotation formed by the arcuate part and the straight part in the drying chamber Since it has a moving space, and furthermore, the air intake and the air intake are provided on the side of the drying chamber, the hot air flows laterally through the space between the mesh shelves. Even if bedding is placed on all the net shelves, the hot air will be evenly distributed and bedding such as futons can be efficiently dried.

Furthermore, the capacity of the blower installed at the air outlet is larger than that of the blower at the air intake, making it possible to create an appropriate negative pressure inside the drying chamber and preventing hot air containing a large amount of steam from leaking outside. In addition, since the heater is installed after the air intake and the blower on the air intake side sends unexpanded air, it has the advantage that its capacity can be small.
