Abstract: An air purifying unit in which leakage of air flowing between a filter and a blowing fan is significantly reduced, and an air cleaning/ventilation device including the same, are provided. In addition, there are an air cleaning/ventilation device detachably installed in a window, used as a ventilation device, and used as an indoor air cleaning device.

Abstract: The dehumidifier, according to one embodiment of the present invention, comprises: a variable compressor which varies the rotation speed of a driving shaft according to an input control signal and adjusts an amount of a refrigerant gas compressed by the rotation of the driving shaft; a condenser for liquefying the compressed refrigerant gas received from the variable compressor; a heat exchanger for cooling flown air by vaporizing the liquefied refrigerant gas, and condensing vapors of the flown air into water to remove the water by using the cooling air; a blower fan for supplying outside air to the heat exchanger by forming an air flow according to the driving speed of a blower motor; and a control unit for generating the control signal according to the input signal so as to adjust the rotation speed of the driving shaft.

Abstract: There is provided a compressor fixing structure capable of preventing vibrations from a compressor from being spread to the entirety of a product in which the compressor is installed. The compressor fixing structure includes: a plurality of support units disposed to have a polygonal structure and protruded from a bottom surface; a support unit anti-vibration rib protruded from a perimeter of each of the plurality of support units; and an outer anti-vibration rib surrounding the entirety of the plurality of support units and protruded from a bottom surface. Spreading of vibrations from a compressor installed in a product is minimized, reducing vibrations and noise generated by the compressor when the compressor is driven.

Abstract: There are provided a compressor noise suppressing structure and a dehumidifier having the same. The compressor noise suppressing structure includes an installation member fixed to a base frame to support and accommodate a component installed within a housing, and a noise-proof member extending from the installation member to cover at least one side of the compressor to block noise from the compressor. According to the compressor noise suppressing structure, noise generated when the compressor is operated is simultaneously blocked by the nose-proof member and the housing, and the installation member and the noise-proof member are configured as a single component, improving assembly characteristics and simplifying a fabrication process.

Abstract: A fixing device for a compressor includes main fixing units to prevent internal vibration generated due to the operation of the compressor and auxiliary fixing units to prevent external vibration generated due to external environment, such as transportation of the compressor, and stably maintains the installation state of the compressor, thus effectively preventing a damage to a refrigerant pipe due to the vibration of the compressor. The main fixing units connect the compressor to the casing, and the auxiliary fixing units cause the compressor to be separated from the casing in a normal state, and allow the compressor to contact the casing when an excessive external vibration is generated, thus preventing unnecessary vibration, generated from the compressor, from being transferred to the casing.
