Reference numeral 3 denotes a bellows tube, the upper end opening of which is connected to the lower end opening of the upper case through a lippet 4. Reference numeral 5 denotes a lower case connected to the lower end opening of the bellows tube by rivets 4, and has a connection port 6 for a hot air fan (not shown). 7 is a net provided above the connection port 6 and having a large number of holes. Arrows indicate air flow.

A conventional drying box is constructed as described above.
For example, put wet clothes in the box and connect to the connection port 6.
Clothes were dried by letting warm air from a hot air fan flow into the box.

[Problems to be Solved by the Invention] In the conventional drying box as described above, when a large number of clothes are stored, they are stacked on top of the net 7, which blocks the opening of the net 7 and obstructs the air flow. Clothes stored in the upper tier cannot be dried until they have been exposed to the humidity of the clothes stored in the lower tier, resulting in poor ventilation and difficulty in drying, resulting in drying problems.

The present invention was made to solve this problem, and its object is to provide a cylindrical body with holes in the center of the net body to improve air flow within the drying box.

[Means for Solving the Problems] The drying box according to the present invention includes an upper case provided with an exhaust port, a lower case provided with an inflow port, an upper frame fixed to the inner side of the upper case, and a lower case provided with the upper case. A lower frame fixed to the inner side, a bellows tube with both open ends disposed between the upper frame and the lower frame, and a tube portion with a hole provided in the center of the bellows tube, which is removably provided inside the bellows tube. The hot air flowing from the inlet formed in the lower case is guided to the exhaust port through the net.

[Function] In this invention, a removable net body is provided inside the bellows tube, and clothing is stored between the central tube part of the net body and the bellows tube, and hot air from the inlet is passed through the net body. The stored clothes are sent upward from the bottom and sides and are also sent to the cylinder in the center.
Dry by blowing air from the bottom, sides and center of the net.

In addition, since the net body is removable, it can be removed and washed when cleaning.

[Example] An example of the present invention will be described below with reference to FIGS. 1 to 11.

In the figure, reference numeral 8 denotes a drying box, to which the hose of the futon dryer shown in FIG. The volume of the drying box 8 can be changed between the operating state shown in FIG. 1 and the stored state shown in FIG. Reference numeral 9 denotes an upper case having an inverted concave shape, which has an upper handle 10 rotatably supported from opposite sides, and a removable lid 11 at the top. The lid 11 is provided with an exhaust port 12 consisting of a large number of holes. 13 is the concave groove 1 of the upper case 9
The upper frame has an inverted L-shaped cross section and is fitted into the upper case 9, and is screwed into a plurality of bosses 17 protruding from the upper surface using screws from screw holes 16 opened in a plurality of stepped portions 15 provided on the upper surface of the upper case 9. ing. 18 is step part 1
A cap 19 covering the heads of the screws protruding from 5 is a recess formed across the upper surface 13a and the outer surface 13b of the upper frame 13, and has a horizontally elongated opening 20 at the lower end of the outer surface. This recess 19 is the upper frame 13
There are four locations located at 90° intervals around the circumference. Reference numeral 21 denotes a U-shaped connecting member, whose upper side 21a is placed on the upper surface of the recess 19, and whose lower side 21b is connected to the opening 20.
The upright portion 21c is inserted into a recess on the outer surface thereof, and is supported by the inner surface of the upper case 9 from the back side of the upright portion 21c toward the upper frame 13. 22 are placed on the bottom surface 13c of the upper frame 13 at 90° intervals.
The ribs 23 provided at several locations are bellows tubes whose upper ends abut against the ribs 22, and the core bar 24 at the upper end connects the lower side 21b, which is the insertion part of the U-shaped connection member 21, and the above-mentioned ribs 22. It is sandwiched and connected to the lower surface 13c of the upper frame 13.

The procedure for connecting the bellows tube 23 and the upper frame 13 is as follows: First, the upper end opening of the bellows tube 23 is brought into contact with the rib 22 provided on the lower surface 13c of the upper frame 13, and then the bottom of the U-shaped connecting member 21 is The connecting member 21 is prevented from falling from the upper frame 13 by inserting the side 21b into the opening 20 and placing the upper side 21a on the upper surface 21a of the upper frame. At this time, the core bar 24 at the upper end of the bellows tube 23 is connected to the lower side 21b of the connecting member 21 and the lower surface 13 of the upper frame 13.
It is sandwiched between c. And this upper frame 13
is fitted into the groove 14 of the upper case 9, and the inner surface of the upper case 9 supports the connecting member 21 from the back side of the upright portion 21c to prevent it from coming off from the upper frame 13. Finally, screws are tightened from the top surface of the upper case 9 to the bosses 17 of the upper frame 13 to secure the upper case 9 in place. 2
5 is an upper case guide wall which is the inner wall of the groove 14 of the upper case 9; 26 is a concave lower frame; the inner bottom surface thereof has four ribs 27 formed at 90° intervals; 27 is brought into contact with the lower end opening of the bellows tube 23. 28 is a lower frame guide wall which is an inner wall of this lower frame 26; 29 is a plurality of drainage holes formed on the inner bottom surface of the lower frame 26; 30 is a plurality of screw receiving bosses formed on the outer bottom surface of the lower frame 26; A recess 19 and an opening 20 similar to those formed in the upper frame 13 are formed in the lower frame 26, and a U-shaped connection member 21 is attached thereto.

The procedure for connecting the lower frame 26 and the bellows tube 23 is the same as the procedure for connecting the upper frame 13 and the bellows tube 23 described above.

However, the lower case 31 that supports the lower frame 26 does not have anything equivalent to the groove 14, and the connecting member 21 is simply supported by aligning the outer surface of the lower frame 26 with the inner surface of the lower case 31. It is screwed onto the boss 30 of the lower frame 26 from the lower surface of the case 31.

32 is a lower handle provided in a lower case recess 33 formed on the outer bottom surface of the lower case 31; 34 is a hot air intake opening opened on the side surface of the lower case 31;
Four convex portions 35 are formed at 90° intervals on the inner surface.
When the hose is inserted, a gap is created between the protrusions 35. Reference numeral 36 denotes a base provided on the inner circumferential surface of the lower frame 26, and 37 is a net having a large number of holes.
A is placed. Reference numeral 38 denotes a cylindrical portion formed in the center of this net 37, and its upper end is at a height such that it comes into contact with the lid 11 in the stored state. Reference numeral 39 denotes a side wall of the net 37, which is spaced a certain distance from the inner surface of the lower case 31. 40 is a bottom wall of the net 37, which is spaced from the bottom of the lower case 31 by a certain distance. 41
is a semicircular shielding surface formed on the surface of the net 37 facing the hot air intake port 34, and only this portion does not have a large number of holes. Arrows in each figure indicate air flow. Also, broken lines indicate clothing.

Next, the operation will be explained. First, pull the upper handle 10 and lower handle 32 of the drying box 8 in the stored state with both hands to stretch out the contracted bellows tube 23. Next, the hose of the futon dryer is connected to the hot air intake port 34. Then, the lid 11 is removed, the damp clothes are stored in the drying box, and the lid 11 is closed again. At this time, care should be taken not to place the clothing on the cylindrical part 38 as much as possible while leaving as much space as possible. After storing the clothes, turn on the futon dryer to generate warm air. The hot air passes through the hose and flows into the drying box 8 from the hot air intake port 34, but immediately after flowing in, the hot air hits the shielding surface 41 and is dispersed to the left and right. As shown in FIG. 7, the dispersed warm air also flows through the holes in the side wall 39, bottom wall 40, and cylindrical portion 38 to dry the clothes.

In addition, water droplets that flow down along the bellows tube 23 during drying pass through the drain hole 29 and accumulate in the lower case 31, so they do not accumulate in the lower frame 26 and the bellows tube portion 2
It has the effect of protecting the core metal 24 of No. 3 from rust and preventing foul odors and rot. In addition, if a large amount of clothing is loaded and it becomes difficult to exhaust the warm air through the exhaust port 12 provided on the lid 11 (during abnormal use), the warm air can be removed from the ribs of the lower frame 26 as shown in Figure 8. 27 by bellows tube 23
The screwing space 4 is inserted through the gap created between the lower frame 26 and the lower frame 26.
2, and from this threaded space 42 the bellows tube 23
Since the exhaust hot air is dissipated upward to the outer periphery, the discharged hot air flows out slowly, and the exhaust can be carried out without making the user feel that the hot air is leaking.

In addition, since a convex portion 35 is provided on the hot air intake port 34 and a gap 43 is provided between the hose and the hot air intake port 34, outside air is drawn through this gap 43 even when the room temperature is high, as shown in FIG. Therefore, the air temperature inside the drying box 8 can be lowered to prevent clothes from deforming and discoloring. Furthermore, when clothes are packed too much, this gap 43 acts as an exhaust port, as shown in FIG. 8, and can prevent the air temperature inside the drying box from rising.

In addition, the upper case guide wall 25 and the lower frame guide wall 2
8 is provided higher than the support position of the connecting member 21, so it not only guides the folding of the bellows tube 23, but also hides the end surface of the bellows tube 23 and prevents the end surface from coming into contact with clothing, thereby preventing damage to the clothing. In addition, even if the connecting member 21 damages the bellows tube 23 and a hole is formed, it will not be visible and the appearance will be good.

In addition, when the side walls 39 and bottom wall 40 are clogged with too much clothing, the air is exhausted from the top of the cylindrical portion 38 as shown in FIG. 8 to prevent the air temperature from rising inside the drying box 8. This protects clothing from deformation and discoloration.

In the above embodiment, the connecting members 21 are provided at four locations on both the upper and lower sides, but they may be provided at three or two locations. Furthermore, in the case of using only one piece, as shown in FIG. 10, a rib 44 may be formed in advance on one side of the frame, and a connecting member 21 may be provided on the other side.

In addition, by providing a shielding surface on the opposite surface of the hot air intake port 34, it prevents hot air from directly hitting one part of the clothing, and also disperses the hot air, thereby preventing uneven drying, discoloration, and deformation of the clothing. It has the effect of preventing
In addition, a space is provided between the side wall 39 of the net 37 and the inner surface of the lower case 31 to allow warm air to flow in, and the warm air is allowed to flow out through holes provided in the side wall, making it easy to clean clothes. It has the effect of being able to dry from multiple directions, preventing uneven drying and shortening drying time.

[Effects of the Invention] As described above, the present invention has the following effects.

The cylindrical part provided in the center of the net body allows hot air to be blown not only from the sides and bottom of the net body but also from the center, allowing efficient drying.

The cylindrical portion provided in the center of the net body supports the material to be dried when the material is to be dried.

Since it is constructed of a bellows tube, it can accommodate drying objects of various lengths.
