Description

The present invention relates to a drying bag used in a futon dryer, and more particularly, to a bag that is dried with the futon inside the drying bag.

A general futon dryer performs drying by placing a drying bag into which warmed air is blown and sandwiching the bag between a futon and a comforter. However, in such a structure, the surface in contact with the drying bag is well dried, but the surface away from the drying bag is not sufficiently dried. In particular, the back of the mattress cannot be ventilated by the floor, and hot air does not escape on this side, making it difficult to dry well.
On the other hand, the following Patent Documents 1 to 5 show a device in which a futon is spread and stored in a dry bag and hot air is blown inside. If it is such a device, since the whole temperature around the futon becomes high, the futon can be further dried.
However, the devices described in Patent Documents 1 and 2 send hot air into the bag that is stored in a state in which the futon is spread inside the dry bag, but the lower surface of the futon is sufficiently dry because the lower surface of the futon is closed. There is a problem that you can not. On the other hand, the devices described in Patent Documents 3 and 4 show that the lower surface of the futon is floated by arranging protrusions on the lower surface of the futon. According to such a structure, the lower surface of the futon is filled with high-temperature air, so that the lower surface of the futon can be sufficiently dried. However, even with such a structure, the outer periphery of the futon can be warmed, but air does not pass through the inside of the futon, which may result in insufficient drying. On the other hand, the device described in Patent Document 5 employs a structure in which the drying bag is divided into two upper and lower layers, the futon is stored in the upper layer, and hot air is sent to the lower layer. According to such a structure, since hot air passes upward from the lower surface of the futon, high-temperature air passes through the futon, so that the inside of the futon can be sufficiently dried.

By the way, in the device described in Patent Document 5, the lower layer on which the futon is placed must be inflated with warm air, but a large wind force is required to lift the heavy mattress, and if the wind force is insufficient, It seems that there is a risk that only the near part will be lifted and the part far from the vent will not be able to dry sufficiently.
In view of such problems, an object of the present invention is to uniformly allow hot air to be ventilated from the lower surface to the upper surface of the futon in the drying bag for the dryer that houses the futon inside, regardless of the wind force. .

In order to solve the above problems, the present invention has the following configuration.
The invention according to claim 1 has an openable and closable opening in which a futon can be put inside, a bag body that can be accommodated in a state in which the futon is spread, and an inner lower surface of the bag body, A flow path that is arranged so that at least the futon can be supported so as not to contact the lower surface, has a hard pipe with a plurality of openings formed on the upper surface, and communicates with an air inlet provided outside the bag body A drying bag for a futon dryer having an air inflow pipe that forms
The invention described in claim 2 is the futon dryer drying bag, wherein the air inflow pipe includes a plurality of substantially straight hard pipes arranged in parallel to each other, and the openings of the hard pipes are soft. A series of meandering flow paths are formed by connecting the pipes.
The invention described in claim 3 is a futon dryer comprising the futon dryer drying bag.

With the configuration as described above, the present invention has the following effects.
According to the first aspect of the present invention, when a futon is installed on the air inflow pipe inside the bag main body, the bag main body is closed, the hot air is sent by connecting the air inflow pipe to the futon dryer main body, It is discharged from the hole provided above the hard pipe through the flow path, and flows into the bag body from the upper surface of the futon through the inside of the futon just above, thereby drying the inside of the futon. At this time, since the weight of the futon is supported by the hard pipe, the hot air can surely be fed into the inside of the futon from the hard pipe portion on the lower surface of the futon regardless of the amount of wind force that sends the hot air.
The invention according to claim 2 arranges the hard pipes in parallel, and the hard pipes are connected by the soft pipes so that the hard pipes are not restrained, so the entire drying bag for the futon dryer is bundled with the hard pipes. Thus, it can be rolled and stored.
The invention according to claim 3 can provide a futon dryer having the above-mentioned effects.

It is a perspective view of the futon dryer concerning an embodiment. It is a perspective view which shows the air inflow tube in the drying bag for futon dryers. It is a longitudinal cross-sectional view of the drying bag for futon dryers which shows a use condition.

Embodiments of the present invention will be described below with reference to the drawings.
The perspective view of the futon dryer D which concerns on FIG. 1 at embodiment is shown. The futon dryer D includes a dryer main body M that blows the same hot air as a general futon dryer, and a drying bag X that is connected to the dryer main body M and a flexible pipe P.
The drying bag X is composed of a bag body 10 and an air inflow pipe 20. The bag body 10 is a flat, rectangular parallelepiped bag having a size and shape that can be accommodated inside with the futon being unfolded, and a certain range of side edges is formed by the wire fastener 11 so that it can be opened and closed. It can be put inside. The bag body 10 is formed of a fine synthetic resin woven cloth, so that it can swell when air is sent into the interior, while the air inside the cloth is exhausted from the eyes of the cloth on the entire surface. ing.

  The air inflow pipe 20 is a tube provided in the bag body 10, and is exposed to the outside from the side surface of the bag body 10 with one end side serving as an air inlet and the outer peripheral edge thereof being airtight. FIG. 2 is a perspective view of the air inflow pipe 20. The air inflow pipe is composed of a main pipe 21 made of hard synthetic resin pipes arranged in parallel at equal intervals, an inlet pipe 23 whose one end is an air inlet, the main pipes 21, and a soft pipe that connects the main pipe 21 and the inlet pipe 22. The connecting pipe 22 is made of a synthetic resin pipe. The connecting pipe 22 connects the main pipes 21 alternately, so that the air inflow pipe 20 forms a single non-branching flow path meandering as a whole. Note that the end portion of the main pipe 21 constituting the end portion of the flow path is closed. Holes 21a are provided on the upper surface of the main pipe 21 at regular intervals. The main pipe 21 is bonded and fixed to the inner surface of the bag body 10 at the lower surface. Thus, when the bag body 10 is expanded, the main pipes 21 are arranged in parallel and can be in the state shown in FIG. Further, since the connecting pipe 22 is formed of a soft material and the bag body 10 is also a soft woven cloth, the main pipes 21 can be brought close to each other during storage. It can be rolled around to make it smaller.

  Next, the usage method of the drying bag X which has the above structures is demonstrated. First, after the bag body 10 is spread on the floor, the user opens the wire fastener 11 of the bag body 10 and places the futon on the air inflow pipe 20. Next, after connecting the inlet pipe 23 of the air inflow pipe 20 and the futon dryer main body M with the pipe P, the dryer main body M is operated. The typical longitudinal cross-sectional view of the drying bag X of the state which accommodated the futon C in FIG. 3 is shown. As shown in the figure, the hot air sent from the dryer main body M is sent upward from the hole 21 a of the main pipe 21 and flows into the bag main body 10 through the futon C. In this way, the hot air passes directly through the futon C, so that the inside of the futon can be efficiently dried and mites can be appropriately eliminated. In addition, since the futon C is supported by the main pipe 21 made of a hard pipe and the air flow path is secured without being crushed, the hot air can be sent to the entire futon regardless of the strength of the blowing amount of the dryer body M, The burden on the dryer main body M can also be suppressed. When the dryer body M is operated for a certain period of time and sufficient drying is completed, after the futon C is taken out from the bag body 10, the work is completed if the bag body 10 is rolled up and stored.

  In the above embodiment, a round pipe is used as the main pipe, but a pipe having another cross-sectional shape such as a square pipe may be used. Moreover, when using a square pipe, the bottom face which contacts the bag main body 10 may not be provided. The size, shape, and number of holes formed in the main pipe can be changed as appropriate.
