Description

The present invention relates to a futon washing/drying device, and more particularly to a futon washing/drying device that can wash a futon in an unfolded state.

Conventionally, it has been impossible to wash futons using household washing machines because the futons are large and heavy.
On the other hand, in recent years some coin laundries have been equipped with large drum-type washing machines that can wash futons, making them more convenient.
However, drum-type washing/drying machines wash rolled-up futons, so they have the disadvantage that it is difficult to clean dirt from inside the futon.

Next, the hot water supply device 30 is operated to supply hot water of about 40 degrees to the futon washing/drying tub 2. When the water reaches above the upper extending pipe section 8 above the futon 40, the supply of hot water is stopped.
Next, the fine bubble generation device 31 is operated. The fine bubble generation device 31 takes in hot water from the futon washing/drying tank 2, generates and mixes countless fine bubbles, and returns the mixture to the futon washing/drying tub 2. Warm water mixed with fine bubbles has extremely high cleaning power due to the bursting impact of the fine bubbles.

Put the detergent into the futon washing/drying tank 2, close the lid 5 (see Fig. 4), switch the switching valve 33 to the first inlet port 36 side, operate the high pressure pump 35, and close the futon washing/drying tub 2. fine bubble hot water is supplied to the discharge pipe 7 under high pressure. Then, the transfer device 22 is operated, and the discharge pipe 7 is reciprocated a fixed number of times from side to side over the entire length of the futon 40 in the vertical width direction between near the left end and near the right end of the futon washing/drying tub 2.
During movement, high-pressure fine bubble water is discharged downward from the upper extension pipe section 8 of the discharge pipe 7, collides with the futon 40 and enters the interior, and in parallel, high-pressure fine bubble water is discharged upward from the lower extension pipe section 9. Fine bubble hot water is discharged, collides with the futon 40 and penetrates into the interior, promoting the bursting of fine bubbles near dirt on the surface and inside of the futon 40, demonstrating a high cleaning effect, and removing dirt inside the futon 40. is extracted quickly and effectively.

(2) Drainage process After about ten to several tens of minutes have passed and the discharge pipe 7 has completed a certain number of reciprocations, when the discharge pipe 7 reaches the left end in FIG. and also stops the operation of the high pressure pump 35. Open the valve (not shown) of the drain pipe 24 at the bottom of the futon washing/drying tub 2 to drain all the washing water in the futon washing/drying tub 2 to the outside.

(3) Rinsing process The hot water supply device 30 is operated to supply hot water of around 40 degrees to the futon washing/drying tub 2. When the water reaches above the upper extending pipe section 8 above the futon 40, the supply of hot water is stopped.
Next, the fine bubble generation device 31 is operated. The fine bubble generation device 31 takes in hot water from the futon washing/drying tank 2, generates and mixes countless fine bubbles, and returns the mixture to the futon washing/drying tub 2. The hot water mixed with fine bubbles has a very high rinsing power due to the bursting impact of the fine bubbles.

Next, the switching valve 33 is switched to the first inlet port 36 side, the high pressure pump 35 is operated, and fine bubble hot water from the futon washing/drying tank 2 is supplied to the discharge pipe 7. Then, the transfer device 22 is operated, and the discharge pipe 7 is reciprocated a fixed number of times from side to side over the entire length of the futon 40 in the vertical width direction between near the left end and near the right end of the tank 1.
During the movement, fine bubble hot water is discharged downward from the upper extension pipe section of the discharge pipe 7 at high pressure, collides with the futon 40 and penetrates inside, and in parallel, fine bubble hot water is discharged upward from the lower extension pipe section. is discharged at high pressure and collides with the futon 40 and penetrates into the interior, promoting the bursting of fine bubbles on the surface and inside of the futon 40, and quickly and effectively removing washing water and dirt from the surface and inside of the futon 40. taken out.

After about ten to several tens of minutes have passed and a certain number of reciprocations have been completed, when the discharge pipe 7 reaches the left end in FIG. stop. Then, the valve (not shown) of the drain pipe 24 at the bottom of the futon washing/drying tub 2 is opened to drain the washing water to the outside.
This rinsing step is repeated one or more times to empty the rinsing water in the futon washing/drying tank 2.

Due to the operation of the pressurized air blower 39, the pressure in the futon washing/drying tub 2 becomes negative, and the outside air without moisture is drawn into the futon washing/drying tub 2 through the gap 25 between the futon washing/drying tub 2 and the front end of the lid 5. flows into. The outside air that has entered the futon washing/drying tank 2 is mixed with moisture that has evaporated from the futon 40, and then is sucked in through a plurality of intake ports of the exhaust pipe 23, and is exhausted to the outside via the exhaust pipe 23 and the pressure blower 39. By doing so, the futon 40 is dehydrated.
At this time, while the discharge pipe 7 is moving, high-pressure air is discharged downward from the upper extension pipe section 8 of the discharge pipe 7, colliding with the surface of the futon 40 or entering the inside, causing moisture on the surface and inside of the futon 40. In parallel, high-pressure air is discharged upward from the lower extension pipe section 9, collides with the surface of the futon 40 and penetrates into the interior, and evaporates the moisture on the surface and inside of the futon 40. This allows the futon 40 to be effectively dehydrated.

After about ten to several tens of minutes have passed and a certain number of reciprocations have been completed, when the discharge pipe 7 reaches the left end in FIG. 1, the movement of the discharge pipe 7 by the transfer device 22 is stopped and the operation of the high pressure pump 35 is stopped. . Further, the operation of the high-pressure pump 35 and the pressurized blower 39 are stopped.

(4) Drying process The hot air supply device 32 is operated to supply hot air for drying at around 40 degrees to the futon washing and drying tub 2.
Next, the switching valve 33 is switched to the second inlet port 38 side, the air compressor 37 is operated, and the hot air from the futon washing/drying tub 2 is supplied to the discharge pipe 7. Then, the transfer device 22 is operated, and the discharge pipe 7 is reciprocated a fixed number of times from side to side over the entire length of the futon 40 in the vertical width direction between near the left end and near the right end of the futon washing/drying tub 2.
During the movement, high-pressure hot air is discharged downward from the upper extension pipe section 8 of the discharge pipe 7, collides with the surface of the futon 40 and penetrates into the interior, and in parallel, flows upward from the lower extension pipe section 9. High-pressure hot air is discharged, collides with the surface of the futon 40, and penetrates into the interior of the futon 40, so that the futon 40 is quickly and effectively dried.

(5) Removal After the futon 40 has been dried through the drying process that lasts from several tens of minutes to several hours as described above, the operations of the air compressor 37, transfer device 22, and warm air supply device 32 are stopped. Then, the lid 5 is opened and the futon 40 is taken out.

According to this embodiment, when washing, the futon 40 is spread out and immersed in washing water containing fine bubbles, and the washing water containing fine bubbles is discharged from the discharge pipe 7 toward the futon. It is possible to reliably clean and remove dirt from the inside of the machine.
