Description

[Detailed description of the invention] [Technical field of the invention] The present invention relates to a futon restoring device used in a futon washing system, and particularly for futons that are sensitive to heat such as feather futons and wool futons. The present invention relates to a futon restoring device that can satisfactorily restore futons.

[Technical background of the invention and its problems]

A futon washing system that washes and recycles the futon as a whole is known, for example, as disclosed in Japanese Patent Publication No. Sho 60-15359.

This futon washing system includes a surface cleaning device that brushes and cleans the surface of futons,
It consists of a washing and dehydrating device that washes and dehydrates futons using centrifugal force, and a restoring device that dries and restores moist futons with high-temperature air.

In addition, the conventionally known restoring device consists of a rotary drum that stores futons inside and is driven to rotate, a heater placed above the rotary drum to heat the outside air to a high temperature, and a heater adjacent to the heater. A primary damper is provided to adjust the amount of outside air supplied to the heater, and an exhaust fan is provided below the rotary drum to exhaust the outside air supplied to the rotary drum.

The futons that have undergone the cleaning and dehydration process are dried in a drying room, etc., and then stored inside the rotary drum of this conventional restoring device, where they are subjected to a restoring action. That is, due to the rotation of the rotary drum, the futon is lifted to the top and then falls under its own weight, and this natural fall is repeated. At the same time, the outside air taken in from the primary damper is heated by a heater to produce high-temperature air, and then this high-temperature air is supplied to the inside of the rotary shell. In this way, the futon is completely dried and restored.

When the futons that have undergone the restoration process are taken out of the restoration machine, the futons become quite hot due to the high-temperature wind. On the other hand, for example, if the futons are feather comforters, woolen futons, blankets, etc., if they are left stacked for a long time at high temperatures, the feathers and wool will deteriorate as these futons are susceptible to heat. There is a risk that the properties may change or, in extreme cases, heat may accumulate and spontaneous combustion may occur. Therefore, unlike cotton blankets, feather blankets, wool blankets, etc. require more careful temperature control within the restoring device.

[Purpose of invention]

The present invention was developed with these points in mind, and when restoring futons that are sensitive to heat, such as feather futons and woolen futons, it is necessary to supply high-temperature air to the inside of the rotating body. To provide a futon restoring device which can prevent heat accumulation in futons by immediately supplying cold air.

[Summary of the idea]

The present invention includes a rotary drum that stores futons inside and is driven to rotate; a heater that is disposed above the rotary drum and heats the outside air introduced into the rotary drum to a high temperature; Futons comprising: a primary damper provided adjacently to adjust the volume of outside air supplied to the heater; and an exhaust fan provided below the rotary drum to exhaust the outside air supplied into the rotary drum. In the restoration device, a cold air supply path for directly supplying outside air into the rotary cylinder is formed at a position above the rotary cylinder, and an air volume of the outside air supplied into the rotary cylinder is provided in the middle of the cold air supply path. It is characterized by a secondary damper that adjusts the

According to the present invention, a cold air supply path for directly supplying outside air into the rotating drum is formed above the rotating drum, and a secondary damper is disposed in the middle of this cold air supply path to adjust the amount of outside air. Therefore, after supplying high-temperature air, if the secondary damper is opened and outside air is directly supplied into the rotary cylinder, the high-temperature air can rapidly cool futons that have become hot and prevent deterioration of futons that are sensitive to high temperatures. can.
