Abstract: A rotary particle sensor assembly and an air cleaner having the rotary particle sensor assembly are disclosed. Particularly, in the present invention, regardless of the orientation of the air cleaner, the rotary particle sensor assembly can always be oriented in the direction of gravity. The rotary particle sensor assembly includes a particle sensor, which measures the pollution level of air drawn into the air cleaner. The particle sensor is supported in the air cleaner so as to be rotatable using a rotating shaft and has a weight at a predetermined position. Thus, the particle sensor can always be oriented in the direction of gravity by the weight regardless of the orientation of the air cleaner. Therefore, the present invention ensures the accuracy of measurement of the pollution level of air.

Abstract: The present invention provides a pulverizing screw, a pulverizing casing and a pulverizer having the same. The pulverizing screw includes a rotating shaft and a drive blade which extends from the rotating shaft in a spiral shape. The drive blade rotates in the pulverizing casing in such a manner as to maintain a predetermined distance between the drive blade and the inner surface of the pulverizing casing to prevent the drive blade from being impeded by the inner surface of the pulverizing casing. The drive blade extends from a first end of the rotating shaft in a spiral shape surrounding the rotating shaft in a clockwise or counterclockwise direction and is connected to a second end of the rotating shaft. The pulverizing casing comprises a spherical body having a space therein. The pulverizing screw is installed in the spherical body so as to be rotatable.

Abstract: There is provided a self-generating bidet that can perform power-generation using water supplied to the bidet or a water tank. The self-generating bidet, injecting water through a nozzle part, includes a water inlet into which water is introduced; a generator generating power through the water introduced by the water inlet; a charging unit storing electricity generated from the generator; and a nozzle passage part provided between the generator and the nozzle part to supply the water passing through the generator to the nozzle part. The self-generating bidet further includes a controller controlling the generator to be driven by opening a passage of the nozzle passage part in order to allow the water to be discharged through the nozzle part when a voltage of the charging unit is lower than a predetermined reference voltage.

Abstract: Provided is a hollow-fibre membrane module comprising a submodule inside which raw water is circulated and water treatment is carried out, and a piping unit which is connected to the submodule and through which the raw water and air and treated water flow, such that flow rates can be increased and energy consumption can be minimised through the circulation of a fluid, and the advantages of internal-pressure type and external-pressure type systems can be incorporated in a composite fashion.

Abstract: Provided are a heat exchanger, a food handler including the heat exchanger, and a manufacturing method of the heat exchanger. The heat exchanger comprises a main body wherein the plurality of flow channels passes through the inside of the heat exchanger in a first direction and a pair of cover members which is fastened to both ends of the main body in the first direction. The plurality of flow channels is composed of a first flow channel which functions as the path for a first flowing fluid which goes in and out through the cover members and a second flow channel which is connected to the side of the main body. Thermal exchange is performed between the first flowing fluid and the second flowing fluid in the direction wherein the first and second flowing fluids cross each other inside of the main body.
