A laundry treatment apparatus includes a cabinet, a drum that is rotatably provided inside the cabinet, a support panel provided on a front surface of the drum, and an infrared sensor installed on the support drum, provided in a direction facing the drum, and configured to receive heat inside the drum. The infrared sensor measures a temperature inside the drum, is disposed at a center based on right and left sides of the drum, and is disposed at an upper end of the support panel.

A clothes dryer includes a drum configured to accommodate an object to be dried; a first sensor configured to sense a dry state of the object to be dried accommodated in the drum; a heating unit configured to heat air supplied into the drum; a blower including a fan configured to generate a flow of the air passing through the inside of the drum; a second sensor configured to sense a temperature of the air discharged from the drum; and a processor configured to control a rotation speed of the drum, a temperature of the air discharged from the drum, and a rotation speed of the fan.

A method of controlling a laundry treatment apparatus includes measuring a temperature of clothes, calculating a temperature amplitude according to the measured temperature of the clothes, classifying a temperature amplitude according to a reference value to classify the clothes into dry and wet clothes, calculating a first ratio as a ratio of the dry and wet clothes of the clothes, calculating a second ratio for normalizing the measured temperature, and determining a drying level of the clothes using the first ratio and the second ratio.

A laundry treatment apparatus includes: a cabinet, a drum rotatably disposed within the cabinet, a suction duct to which air discharged from the drum flows, a circulation flow path connected to the suction duct and configured to guide the air from the suction duct, an inflow duct connecting the circulation flow path to the drum such that the air received from the circulation flow path flows back to the drum through the inflow duct, a circulation fan configured guide the air between the suction duct and the inflow duct, a heat exchanger that is disposed at the circulation flow path and that is configured to perform heat exchange with the air, and an UV sterilizer disposed at a space that is defined in the circulation flow path at a position above a front surface of the heat exchanger, the sterilizer being configured to irradiate UV light to the heat exchanger.

The present invention relates to a combination washer dryer system (100) with a convertible venting and condensing drying mode which can be switched from a vented drying mode to a condenser drying mode and vice versa facilitated by an electronically controlled switch. The said combination washer dryer system (100) comprises of an electronic control panel (101), a venting unit (102), and a condensing unit (103).

A washing machine is provided. The washing machine includes a drum, a detergent supply unit for supplying detergent to the drum, a turbidity sensor for detecting the turbidity of water inside the drum, memory storing one or more computer programs, and one or more processors communicatively coupled to the drum, the detergent supply unit, the turbidity sensor, and the memory, wherein the one or more computer programs include computer-executable instructions that, when executed by the one or more processors, cause the washing machine to control the detergent supply unit to supply the detergent to the drum in case that a washing cycle starts, detect the water turbidity by using the turbidity sensor in case that a predetermined time period elapses after the washing cycle starts, obtain result information by comparing the detected water turbidity with a critical value, and store the obtained result information in the memory.

An embedded temperature sensor may be attached to or otherwise associated with a textile in order to measure one or more temperatures of the textile. Temperature information received from one or more embedded temperature sensor(s) throughout the course of a dryer cycle may be analyzed to determine dryness of one or more textiles in a dryer, determine whether one or more textiles in the dryer are overdry, generate an indication of the dryness of the one or more textiles in the dryer, and/or to control one or more dryer cycles of the dryer, such as by automatically turning-off the dryer when one or more of the textiles in the dryer are determined to be dry. The embedded temperature sensor may further be used to validate a cleaning process in a cleaning machine.

A washer comprising: a first heater to heat washing water; a second heater to heat air; a fan to guide air; a memory to store one or more programs; and a controller which is electrically connectable to the first heater, the second heater, the blower fan, and the memory. The washer is controlled by the controller to sequentially perform a washing cycle, a first rinsing cycle, a second rinsing cycle, a spin-drying cycle, and a drying cycle, wherein the second rinsing cycle includes an operation of heating the washing water through the first heater and an operation of rotating the drum, and the spin-drying cycle may include heating the air through the second heater in at least a part of a section based on a rotation speed of the drum, and guiding the heated air into the drum by using the blower fan.

The power P of the heater of a dryer is regulated in order to heat up the air used to dry washed articles placed in the drying chamber to a temperature close to a set point temperature T.sub.SET. The output signal of the regulator of the heater is used to estimate the moisture content of the fabrics and to terminate the drying cycle when a predefined moisture level is reached.

A dryer includes a cylinder, a heater, a motor, a temperature sensor and a controller. The heater heats air and delivers the heated air into the cylinder. The motor is used to drive the cylinder to rotate. The temperature sensor includes a thermopile array sensor and a signal processor. The thermopile array sensor is used to sense an infrared light radiated from clothing and output a sensing signal. The signal processor is used to process the sensing signal to obtain at least one of a temperature distribution uniformity and an average temperature of the clothing, and output a control signal according to the at least one of the temperature distribution uniformity and the average temperature of the clothing. The controller determines to stop the drying schedule according to the control signal. The above-mentioned dryer can stop the drying schedule automatically, so as to save energy.
