Description

[Detailed Description of the Invention] (Industrial Application Field) This invention relates to a futon regeneration device using steam that kills and disinfects dust mites and bacteria attached to futons, and also dries them.

(Prior art) In Japanese Utility Model Publication No. 54-35024, a hot air generator, an ultraviolet irradiation light, and a vaporizer for vaporizable organic solvents and disinfectants are installed in a drying room, and the hot air from the hot air generator is used to remove organic solvents. There is a known device that vaporizes a solvent and a disinfectant, irradiates ultraviolet rays onto a futon hung indoors, and at the same time ventilates the vaporized gas to sterilize, disinfect, and dry the futon.

(Problems to be Solved by the Invention) The above-mentioned device is a large-scale facility, which increases the cost, and the vaporized organic solvent and disinfectant gas are toxic, so sufficient care must be taken in handling and exhausting them.

(Means for solving the problem) Therefore, the futon regeneration device using steam according to the present invention is placed on a long and narrow table slightly longer than the length of the futon.
A narrow steam ejection box that spews steam from the top surface of approximately the same length as the above-mentioned table, and a narrow drying box that spews heated air from the top surface are installed adjacent to each other in parallel, and the steam of the above-mentioned table It is characterized in that projecting support frames for supporting futons thereon are removably provided on the side where the spouting box is located and the side where the drying box is located, respectively.

(Operation) Lay out the futon to be recycled and place it on the support frame extending from the side of the stand where the steam jetting box is located, and gradually shift the futon by hand toward the support frame on the side of the stand where the drying box is located. move it. This allows the futon to kill dust mites and bacteria by letting the steam ejected from below pass through the inside of the futon as it passes over the steam ejecting box, and then heat the futon to pass through the inside as it passes over the drying box. Air removes moisture and dries.

(Example) In the illustrated example, 1 is a long and narrow platform with a length of about 2 m, which is slightly longer than the length of a futon, and a width of about 1 m. A narrow steam ejection box 2 is installed, and two rows of narrow drying boxes 3 each having a width of about 15 cm in this embodiment are installed on the remaining upper surface. Incidentally, the lengths of the steam ejection box and the drying box are approximately the same as the length of the table 11. Further, support frames 4 and 5 for supporting futons thereon are protruded and attached to the side of the stand 1 where the steam jetting box 2 is located and the side where the drying box 3 is located, respectively.

Reference numeral 6 denotes a steam guide pipe from the boiler 7 that is piped downward along the steam ejection box 2, and connects multiple branch pipes 8 at intervals to uniformly supply steam to the entire length inside the steam ejection box. It is arranged like this. In this embodiment, in order to supply steam more uniformly into the steam ejecting box and ejecting steam uniformly from the entire top surface of the steam ejecting box, a steam 9 is installed in the box directly above the branch pipe 8 that opens at the bottom of the box. is provided to disperse the steam supplied into the box, and the top surface of the box is closed with a porous punching plate 10 (metal plate), on which a glass wool layer 11 is spread and covered with a fabric 12 (Fig. 4). ).

In addition, 13 is a drain discharge pipe from inside the steam ejection box,
14 is a steam flow rate regulating valve connected to each branch pipe 8;
Reference numeral 15 indicates a steam opening/closing valve connected to the steam guide pipe 6 upstream of the part to which the branch pipes 8 are connected. The boiler 7 may be one that has a steam pressure of about 5 to 7 kg/cm ² and is used in ordinary cleaning shops.

In addition, the above-mentioned support frames 4 and 5 are assembled by welding metal pipe materials in a lattice shape in this embodiment, and the horizontal bars 16 are passed through the support pipes 17 attached to the legs 1' of the table 1, and the setscrews 18 are used to secure the support frames 4 and 5. By doing this, the amount of overhang from each side of the stand 1 can be adjusted within the range of about 50 to 80 cm, so that it can be adjusted to suit the width of the futon, and when not in use, loosen the setscrews 18 to support it. It is removed from the pipe 17 so as not to take up space.

Further, each drying box 4 has its upper surface covered with a punching plate, houses a heater 19 inside, and has a blower 2.
0. Air supplied into the box through the duct 21 is heated by the heater 19 and is blown upward through the holes in the punching plate. The heater 19 may be of an electric heating type or may be one using steam from the boiler 7 described above.

In this embodiment, since the drying boxes 3 are arranged in two rows, air is supplied from the blower 20 to the drying box 3a on the side closer to the steam ejection box 2, and a part of the air heated in this drying box 3a is The air is blown into the other drying box 3b through the connecting duct 22, heated further by a heater, and ejected.

The futon 23 to be dried is laid out on the support frame 4 with one side placed on the steam jetting box 2, as shown by the solid line in Fig. 3, and the futon 23 is held in the direction of the arrow by hand and moved little by little until the final stage is reached. Then, move it onto the support frame 5. The speed of movement depends on the width of the futon, but the time required to cross over the steam jetting box 2 should be about 1 to 2 minutes.

As a result, the futon is exposed to steam from below as it crosses over the steam jet box 2, and the steam passes through the futon skin and penetrates into the cotton inside, killing dust mites and bacteria with heat and disinfecting them. Loosen hardened cotton etc. Then, as it crosses over the drying box 3a, it is exposed to heated air from below, and the heated air dries futons, cotton, etc. that have been somewhat humidified by the steam. Next, drying box 3b
As the futon crosses over it, it is exposed to higher temperature heated air, completely drying it and making it fluffy.

(Effects of the invention) As described above, according to the invention, the steam kills and disinfects the dust mites and bacteria in the futon, and the heated air dries it, so there is no danger in handling it, and there is also no possibility of causing pollution problems. Futon can be regenerated with a simple structure. In addition, since both the steam jetting box and the drying box are narrow, steam and hot air can be spouted uniformly from the entire top surface without requiring a complicated internal structure, and each support frame can be removed. Combined with this, the support frame can be removed when not in use, reducing the installation space and keeping it out of the way.

In addition, lay out the futon flatly on the support frame on the side where the steam ejection box is located, and then manually move the futon over the steam ejection box and the drying box to the support frame on the side where the drying box is located. Since you only need to pull it to move it, it doesn't take much effort to flatten the futon and move it.
