Abstract: A method for detecting a degree of blockage of an exhaust duct includes detecting the temperature of air in an intake and exhaust system, calculating a rate of change of the detected temperature, and determining a degree of blockage of the exhaust duct based on the detected temperature and the rate of change of the detected temperature.

Abstract: A clothing dryer includes a drum to receive clothing, a first heater, a second heater having a capacity smaller than a capacity of the first heater, a temperature sensor to sense temperature of air exhausted from the drum and a dryness sensor to sense dryness of the clothing received in the drum. The control method of the clothing dryer includes simultaneously turning on the first heater and the second heater; alternately turning on and off at least one of the first heater and the second heater when a value of the temperature sensed by the temperature sensor reaches a predetermined temperature; and maintaining one of the first heater and the second heater in a turned-on state when a value of the dryness sensed by the dryness sensor reaches a predetermined dryness.

Abstract: A clothing dryer and a control method thereof that adjusts a heater capacity based on a humidity change amount (a drying rate) in a second half of a drying period to reduce power consumption without increase of drying time. The clothing dryer includes a drum to receive clothing, first and second hot air heaters, having different capacities, to supply hot air into the drum, a humidity sensor to sense internal humidity of the drum, and a controller to calculate a humidity change amount in the drum, to compare the calculated humidity change amount with a predetermined change amount, and to control only one having the relatively small capacity selected from the first and second hot air heaters to be operated when the humidity change amount is greater than the predetermined change amount.

Abstract: A clothing dryer capable of effectively drying a small amount of substance, and a control method thereof by changing an algorithm of a sensor-dry course, which is configured to control an operation rate, a degree of drying or a temperature of drying, to be adapted to the small load of substance in a case where the substance to be dried has a small load when compared to the entire volume of the clothing dryer, so that the drying efficiency is enhanced regardless of the load of the substance, and a separate option button is provided for a sensor-dry course, so that a small load of substance is dried adaptively to the material characteristic of the substance for a respective dry course, thereby enhancing the drying efficiency.

Abstract: A dryer and a control method thereof, in which load of an object to be dried is detected using a sensor which has less risk of contamination and an anticipated drying time based on the detected load is accurately determined and displayed. The dryer includes a rotatable drum to accommodate the object, a front support installed at an entrance of the drum to support the drum, a rear support installed at an opposite side of the entrance of the drum to support the drum, an exhaust hole formed in the front support, through which interior air of the drum is discharged, and a humidity sensor installed to the front support at a position adjacent to the exhaust hole, the humidity sensor being located upstream of the exhaust hole in a rotating direction of the drum to detect humidity of the air to be introduced into the exhaust hole.

Abstract: The present invention relates to a toilet bowl including a rotary discharge pipe. A toilet bowl according to the present invention includes: a bowl on which a user sits; an outlet disposed behind the bowl; a discharge guide pipe communicating with the outlet, and connecting to a pipe embedded in a floor to discharge water; and a rotary discharge pipe having a discharge hole in the top thereof, and an inflow hole in an end thereof. According to the present invention, both the restoring force generated from a balancing structure of the rotary discharge pipe and torque generated from the kinetic energy of water (wastewater) discharged from the bowl are used to operate the rotary discharge pipe, thereby reducing the possibility of malfunction. In addition, since the toilet bowl has a simple structure, the manufacturing cost thereof can be decreased.

Abstract: The present invention relates to a drain device for draining wastewater, urine, etc. through a drainpipe and blocking bad odors emanating from the drainpipe, and more particularly, to a drain device comprising: an outer container coupled to a top of the drainpipe, a cover seated on a top of the outer container, a conical sloped plate coupled at a lower center of the cover, and a blocking layer formed in a trapezoidal cylindrical shape and coupled between the cover and the sloped plate, the blocking layer having a narrow upper inlet, a wide lower outlet, and a bent portion formed below the upper inlet. Accordingly, water is not left remaining, foreign objects are prevented from being entrapped and are discharged more easily, and the drain device can be reliably used for a long period of time without deforming.

Abstract: The object of the present invention is to provide an apparatus for mounting an engine for automobiles with an engine mount fixed to the top surface of an inner part of a front side member. This engine mounting apparatus has a reinforcing bracket set within the inner part of the front side member while being welded to the interior surface of the inner part. In addition, a pipe nut is firmly and vertically set in the reinforcing bracket and engages with a locking bolt, which mounts a hydro-mounting cup of the engine mount to the top surface of the inner part of the front side member. In this apparatus, the vibration impact from the engine is applied to the sidewall of the pipe nut. The engine mounting apparatus of this invention is thus improved in its structural strength and in its vibration intercepting effect, and so it effectively reduces vibration noise of the engine during operation of the engine.
