This is a hose provided with a connection tube 9 in a shape of a circle.

Reference numeral 10 denotes a supporting portion for supporting the open end of the connecting tube 9 provided at a predetermined height from the bottom of the main body at a lower portion of one side of the main body 1 and 11 includes a switch for operating the hot air generator 6 It is a timer. In FIG. 2, reference numeral 12 denotes a drying mat formed in a rectangular bag shape with a cloth or the like having air permeability as a whole, and a communication port 13 into which the connection tube 9 of the hose 7 is inserted and connected is provided at one short edge. Have been. 14 is a futon, 15 is a mattress, and 16 is a bed. Reference numeral 17 in FIG. 1 denotes a storage portion of the hose 7 which is recessed on the side surface of the main body 1.

FIG. 3 shows a detailed structure of the connection port 9. A partition wall 22 having an inverted V-shaped cross section is provided integrally at the center of the inside of the outlet port 19 at the tip of the connection port 9.
Divided. Reference numeral 20 denotes an outlet opening on the side surface of the connection port 9 corresponding to the outlet 19, and this side outlet is provided at a position facing the opposite side of the main body when the hose 7 is stored in the main body storage portion 17. ing. Reference numeral 21 denotes an engaging portion which is hooked on the drying mat so that the connecting tube 9 does not come off when the connecting tube 9 is inserted into the communication port 13 of the drying mat 12.

In the futon dryer constructed as described above, the drying mat 12 is previously placed between the futon 14 and the mattress 15 and the hose 7 is taken out of the storage section 17 on the side of the main body 1 and connected. The mouth 9 is inserted into the communication port 13 of the drying mat 12 to connect them. In this state, when the timer 11 is operated to operate the hot air generator 6, the air sucked from the suction port 2 of the main body 1 is heated by the heating element 5 to become hot air, and the hose 7 is discharged from the outlet 3. Further, it is supplied into the drying mat 12 through the connection port 9.

Since an inverted V-shaped partition wall 22 is provided at the front end outlet 19 of the connection port 9, warm air is guided by the inclined surface of the partition wall 22, as shown by the broken line in FIG. Supplied left and right. For this reason, the warm air uniformly spreads to every corner of the drying mat 12, and as a result, the hot air uniformly flows out from the entire surface of the drying mat, so that the entire bedding can be dried evenly.

Embodiment 2 FIG. FIG. 6 is a sectional view of a connecting tube showing another embodiment of the present invention, and FIG. 7 is a plan view showing a flow of warm air in a drying mat. In FIG. 6, reference numeral 7 denotes an expandable and contractible hose as in the first embodiment, 9 denotes a cylindrical connecting tube fixed to the distal end of the hose 7, and has an inverted V-shaped cross section at the center of the inside of the distal end blowing portion 19. The partition wall 23 is formed integrally, and the bottom of the partition wall 23 is horizontally cut out to provide an auxiliary outlet 24, thereby dividing the outlet portion into three parts. The V-shaped partition wall 23 has a width H2 of the auxiliary outlet 24 smaller than a width H1 of a hot air inflow side end formed between the partition wall 23 and the inner surface of the connection cylinder 9. .

In the futon dryer constructed as described above, when the connecting tube 9 is inserted and connected to the communication port 13 of the drying mat 12 and the hot air generator 6 is operated as in the first embodiment, the hot air is 9 is divided into three flows by the partition wall 23 at the front end blowing portion 19, and particularly the flow along the inner peripheral surface of the connection tube 9 is guided by the inclined surface, spreads in the left-right direction, and is supplied into the drying mat 12. You. At this time, as shown by the broken line in FIG. 7, the warm air is supplied straight from the auxiliary outlet 24 corresponding to the space between the partition walls 23, and the warm air is supplied from the outlet in the left-right direction. The supply air volume varies depending on the dimensional difference in the opening width of the inflow side end of the wall 23.

That is, a small amount of hot air is supplied to the central portion of the drying mat 12 and a large amount of hot air is supplied to the left and right sides thereof. As a result, a sufficient amount of warm air flows out uniformly from the entire surface of the drying mat 12, and the bedding can be dried evenly.

Embodiment 3 FIG. FIG. 8 is a cross-sectional view of a connecting tube showing still another embodiment of the present invention, and FIG. 9 is a plan view showing a flow of warm air in a drying mat. 8, reference numeral 7 denotes a telescopic hose, 9 denotes a cylindrical connecting tube fixed to the distal end of the hose 7, and has a substantially inverted V-shaped cross section in which a bottom portion is formed flat at the center of the inside of the distal end blowing portion 19. Partition wall 25
Are formed integrally, and an auxiliary outlet 26 is opened at the bottom of the partition wall 25. As a result, the outlet 19 is divided into three parts. Reference numeral 27 denotes a pair of outlets provided on each side of the connecting cylinder 9 facing the partition wall 25. In addition, connection port 9
The opening edge of the tip blowing portion is formed in an expanded shape.

In the futon dryer constructed as described above, when the connecting tube 9 is inserted and connected to the communication port 13 of the drying mat 12 and the hot air generator 6 is operated as in the first embodiment, the hot air is 9 is divided into three flows by a V-shaped partition wall 25 and an auxiliary discharge port 26 at the front end outlet 19, and particularly, the right and left flows along the inner peripheral surface of the connection cylinder 9 are formed on the inclined surface of the partition wall 25. After being guided, it spreads right and left and is supplied into the drying mat 12. That is, as shown by the broken line in FIG. 9, the warm air flowing in the left-right direction of the outlet 19 is
Both the momentum and the blowing amount are large, and a sufficient amount of warm air is supplied to the farthest corner of the drying mat 12.

At the same time, the auxiliary outlet 2 of the partition wall 25
6, a small amount of warm air flows straight out from the center of the tip outlet 19, and further, the side outlet 27.
From the direction toward the front corner of the drying mat from the momentum than the amount of warm air, the amount is small, but a predetermined amount of warm air flows out,
It is supplied toward each corner of the drying mat 12. Therefore, as a result, a sufficient amount of warm air is uniformly supplied into the drying mat, and the bedding can be dried evenly.

[0019]

As described above, according to the first aspect of the present invention, since the hot air flows into the inside of the drying mat so as to spread to the left and right, the hot air reaches the farthest corner of the drying mat. And the futon can be dried efficiently and evenly.

According to the second aspect of the present invention, since the hot air is supplied to the center and the left and right directions of the drying mat, the hot air is supplied not only to the farthest corner of the drying mat but also to the center. It is possible to dry efficiently evenly because the warm air spreads throughout the drying mat and the futon is even.

Further, according to the third invention, the warm air is supplied to the center and the left and right directions of the drying mat, respectively.
In addition, since the left and right air blowing rates are larger than those at the center, warm air can be uniformly supplied as a whole into the drying mat in a balanced manner, and the drying mat can be efficiently dried evenly. Furthermore,
According to the fourth invention, in addition to the center and the left and right,
Did you supply hot air from the side into the drying mat?
Warm air spreads throughout the drying mat and unevenness of the futon
And can be dried efficiently.
