Provided is a drying system capable of determining if the number of on/off switching unitings of a heating mechanism exceeds a preset number over a preset duration, and reducing the amount of heat that the heating mechanism radiates, in order to extend the service life of the heating mechanism and a switching uniting mechanism

Drying apparatus and method for controlling the same

A drying apparatus and a controlling method thereof are provided. During an initial phase of drying operation according to a selected drying cycle, a point of terminating the drying operation is calculated based on a moisture level sensed by a moisture sensor and a moisture output quantity stored in the storage. Drying is performed up to the calculated point of drying operation termination.

Drying apparatus, and controlling method of the same

A dryer and a dryer control method using a sensing unit and a timer to vary drying operations depending on the state of drying laundry are disclosed. The method for controlling an automatic dryer having a drying part including a heater, a fan, and a drum includes the steps of operating the drying part while monitoring an internal temperature and an internal humidity of the drum, continuously operating the heater, the fan, and the drum until the internal temperature reaches a predetermined temperature, and operating the fan intermittently when the internal temperature reaches the predetermined temperature. The method further includes operating the heater intermittently when the internal humidity reaches a predetermined humidity, discontinuing heater operation upon lapse of a first predetermined time, discontinuing fan operation upon lapse of a second predetermined time, and discontinuing drum operation upon lapse of a third predetermined time.

The present invention relates to a dryness measuring device, and more particularly the dryness measuring device for sensing a dryness status of laundry in drying. The present invention is to provide an electrode sensor for sensing the dryness status of the laundry and measuring a current dryness status by a variance of a voltage which is charged in capacitor based on a variance of resistance of the electrode sensor. And, the present invention minimizes outside effect by discharging of the charged voltage of the capacitor by designated periods.

Dryness measurement device

A bolometric humidity sensor, cooker having the same applied thereto, and method for controlling the cooker are provided. The bolometric humidity sensor has two static bolometric temperature sensors for detecting humidity more accurately. A cooker may have such a bolometric humidity sensor fitted to one side of a bracket on an air outlet for deflecting air flowing out of the cooker. This arrangement allows for more accurate detection of the humidity in the cooking chamber. A method of controlling a cooker could include the use of such a sensor to permit a cooking time period to differ depending on whether the cooked food is wrapped.

An apparatus for controlling gas valves in a gas drier is provided. The apparatus includes an igniter, a closed flame detection switch and a sustaining relay. The igniter, which starts a flame, connects to a first terminal which provides a power signal with respect to a neutral terminal. The closed flame detection switch is connected between the igniter and the neutral terminal thereby receiving the power signal via the igniter. The closed flame detection switch also detects a flame by opening. The sustaining relay provides an alternative path of conduction with respect to the closed flame detection switch.

Gas drier

A drier module, for use in a drier having a drier motor and one of two heat generation devices, namely gas or electric, is an interchange module of a drier of a gas or electric type and may be connected to a drier motor and to a gas control circuit of a gas drier or to an electric heater of an electric drier. During drier assembly, the module is adaptively modified, for example, by setting a switch position according to a desired mode, i.e., the intended drier type. The module includes a selection switch for selecting one of a gas mode and an electric mode; a first connector providing a connection to the drier motor and to a first heat generation device; a second connector providing a connection to the first heat generation device and to a second heat generation device; a microprocessor, electrically connected to the first and second connectors, for detecting a presence of an error condition with respect to the selected mode of the selection switch, based on the connections of the first and second connectors; a first relay, electrically connected between the microprocessor and first connector, for controlling power to the drier motor; a second relay, electrically connected between the microprocessor and first connector, for controlling power to the one of the two heat generation devices; a power supply for providing, under control of the microcomputer, operational power for the drier motor and first and second heat generation devices; and a display for displaying a message indicating the presence of the error condition.
