Axial Gas Or Vapor Flow Patents (Class 34/609)
  • Patent number: 7895771
    Abstract: A clothes dryer has a thermal insulation pad placed in a confined space in the dryer cabinet between the blower fan housing and the dryer cabinet side wall closest to the blower fan housing. The thermal insulation pad is press fit into the space so as to take up much of the volume of the confined space preventing the accumulation of dust or lint over time in the confined space while also preventing the flow of oxygen to the confined space. Accordingly, the thermal insulation pad reduces the risk of a fire starting in the confined area of the dryer cabinet between the blower wheel housing and the adjacent side wall of the cabinet. A thermal insulation pad also acts as sound insulation.

  • Patent number: 7024795
    Abstract: A drying apparatus having a purpose of shortening a drying time of laundry, comprising an accommodating chamber in which the laundry is accommodated, and executing a washing operation of the laundry and a drying operation after end of the washing operation in the accommodating chamber, the machine comprising: a refrigerant circuit in which a compressor, a gas cooler, an expansion valve, and an evaporator are successively connected to one another in an annular form via a piping; an air circulation path for discharging air which has exchanged heat with the gas cooler into the accommodating chamber by a blower to exchange the heat of the air passed through the accommodating chamber with the evaporator; and a control device for operating the compressor and the blower to perform the drying operation, wherein the control device starts the operation of the compressor before entering the drying operation.

  • Patent number: 5925192
    Abstract: Substantial amounts of particulate soils in garments can be removed by agitation in gas-jet in a solvent-free, low-pressure environment. The ability of the present gas-jet agitation system to remove particulate soils from garments and fabrics rivals that of conventional dry-cleaning processes which agitate the garments and fabrics while immersed in solvent. Thus, a dry-cleaning operation may consist of a solvent-immersion step for removing soluble soils and a gas-jet agitation step to remove particulates. Considerable savings in equipment and operating costs may be realized in the practice of the invention, since solvent flow rates need not be boosted to provide necessary agitation for particulate soil removal. The savings achievable by employing gas-jet agitation are even more pronounced in dense phase gas dry cleaning systems, which require pressurized environments to maintain a liquified solvent.
