A washing machine and a control method therefor are disclosed. The washing machine comprises: a sensor for emitting white light, which includes infrared (IR) light, at washing water and receiving, from the white light emitted at the washing water, visible light of a specific wavelength and infrared light of a specific wavelength, which are reflected by the washing water or penetrate the washing water; and a processor for determining turbidity and the color of the washing water on the basis of the intensity and patterns of the visible light and the infrared light of the specific wavelengths, which are received from the sensor, and controlling an operation of the washing machine on the basis of the turbidity and the color of the washing water.

Washing machine and control method therefor

An air cleaner and an oil mist filter are disclosed. The air cleaner includes a main body, and a filter device. The filter device includes at least one dust filter configured to filter external air and an oil mist filter configured to filter oil mist. The oil mist filter includes a stationary filter including a plurality of first baffles, and a movable filter including a plurality of second baffles respectively corresponding to the plurality of first baffles. The movable filter is movably disposed on one side of the stationary filter to be moved to first or second position. The oil mist filter is provided with a first air path in the first position, the first and second baffles are positioned closest to each other. The oil mist filter is provided with a second air path in the second position, the first and second baffles are farthest away from each other.

Oil mist filter and air cleaner having the same

Disclosed are an electronic device for food management and a control method thereof. A control method of an electronic device for food management includes measuring intensity of light, which is irradiated with food and reflected, by wavelengths using an infrared sensor; obtaining state information of the food based on the measured light intensity information; and adjusting at least one of temperature and humidity of an area where the food is disposed in the electronic device based on at least one of the obtained state information and preset usage plan information of the food. Accordingly, food which is managed in an optimal state in consideration of a state of a food stored in an electronic device and a using method (consumption period and consumption method) of the food can be provided to a user.

Electronic device for food management and control method thereof

A formaldehyde detecting apparatus includes a formaldehyde sensor configured to measure concentration of formaldehyde in air; a printed circuit board on which the formaldehyde sensor is disposed, the printed circuit board including a signal processor configured to process a signal output from the formaldehyde sensor; a fixing member disposed on the printed circuit board, the fixing member configured to fix the formaldehyde sensor, wherein the fixing member prevents the formaldehyde sensor from oscillating with respect to the printed circuit board by external vibration; and a power supply configured to supply a voltage capable of stabilizing an output signal to the signal processor.

Formaldehyde detecting apparatus, and air treatment apparatus having the same

An air purifier includes a main body having an inlet configured to receive air and a discharger configured to discharge the air. The air purifier also includes a filter disposed within the main body and configure to purify contaminates from the air. The air purifier also includes a contamination sensor disposed adjacent to the filter and integrally includes a light emitter configured to emit a light toward the filter and a light receiver configured to receive the light emitted from the light emitter.
