  • Patent number: 9146056
    Abstract: A dryer is provided. The dryer may include an expansion valve that may be varied in response to changes in operation mode. The dryer may be a condensation type heat pump dryer, and, in an operation method thereof, the expansion valve may be varied according to an on/off of a solenoid valve corresponding to a selected operation mode. In a first operation mode the heater may be turned on so that heating is supplied by both the heat pump and the heater to provide for rapid drying. In a second operation mode the heater may be turned off to provide for more economical operation. By employing multiple operation modes, a required refrigerant flow rate may be controlled.

  • Patent number: 8241466
    Abstract: A spiral double-tube structure including an inner tube for introducing a solvent vapor resulting from vaporization within a distillation still and an outer tube which a coolant gas cooled by an outdoor machine is passed through is disposed in a buffer tank; the solvent vapor is directly cooled from the surrounding area by the coolant gas with a large temperature difference and thus condensed into a liquid state; by means of an ejector, the liquid is mixed with the solvent suctioned from the buffer tank and returned into the buffer tank; since the solvent in the buffer tank is also directly cooled by the coolant gas, the cooling efficiency is high; accordingly, both the solvent vapor generated from the distillation still and the solvent in the buffer tank for reducing the pressure inside the distillation still can be efficiently cooled without using cooling water, and downsizing of the apparatus can also be attained.

  • Patent number: 7971371
    Abstract: A clothes dryer has a degree of dryness control system that is responsive to moisture level of clothing articles tumbling in a drum and a target moisture value to control the drying cycle of the clothes dryer. The clothes dryer has a load size parameter producing module and an air flow detection parameter module. These modules generate one of two parameter conditions used by the processor to modify or select an appropriate moisture target value. The load size producing parameter module generates one of a small load input parameter and a large load input parameter. The air flow detection module produces one of a first and second air flow parameter to be utilized by the degree of dryness processor. As a result, the processor selects one of four target moisture values from these conditions.

  • Publication number: 20080115540
    Abstract: According to the present invention, a highly safe dry cleaner is provided, which ensures safety without the danger of ignition in a drying process even if so-called microcomputer runaway occurs. The dry cleaner includes a relay sequence controlling circuit (71). The relay sequence controlling circuit (71) includes a serial connection of a first valve (V27) to be controlled, a first switch (77) which controls the turn-on of the first valve (V27) and a second contact (76a) provided in a second relay (76). A detection circuit (79) which controls the second contact (76a) is connected to the serial connection. Thus, the first valve (V27) is maintained in an inactive state irrespective of a first switch turn-on control performed by a control section (81) until the detection circuit (79) performs a predetermined operation to turn on the second contact 76a.

  • Patent number: 6868700
    Abstract: The object is to avoid contaminating the washing conversely by contaminated detergent and provide a dry cleaning machine and dry cleaning method, solving hygienic issues. In a dry cleaning machine which supplies detergent from a detergent tank 11 to a washing tank 10 and washes the washing in the washing tank 10 and treats detergent used in the washing tank 10 by a filtering tank 16 and sends the treated detergent to the washing tank 10 to use detergent cyclically, wherein contaminating the washing conversely by washing can be prevented, as detecting contamination level of detergent discharged from the washing tank 10 while supplying detergent to the washing tank 10 and washing the washing, and when the detergent contamination level reached a prescribed threshold level, storing the detergent discharged from the washing tank 10 temporarily and sending the detergent to a distiller 14 and supplying fresh detergent from the detergent tank 11 to the washing tank 10.
