An air conditioner includes a blower case to guide air blown by a blowing fan to an indoor discharge port. The blower case includes a discharge guide space to guide discharged air to the indoor discharge port, and an air distribution member positioned in the discharge guide space to guide distribution of the discharged air. The air conditioner has uniform volume and velocity of air discharged through an indoor discharge port, and suppresses blowing noise from being generated from the indoor discharge port.

An air purifier includes a bell-mouth having an enhanced structure to prevent an increase of noise at a particular frequency when air flows into the blowing fan through the bell-mouth. The air purifier includes a housing, a filter unit and a blowing fan placed inside the housing, and a bell-mouth placed toward an intake side of the blowing fan. The bell-mouth includes an inlet port formed at a center of the bell-mouth, a flow guide extending from a periphery of the inlet port toward the blowing fan, and a flat section positioned to discontinue the flow guide to increase a distance between the blowing fan and the bell-mouth. The flat section is formed at the section in the range of about 240°˜330° with respect to a starting point of a scroll inside the bell-mouth. The flat section may have a saw-tooth shape to effectively distribute air passing therethrough.

An air conditioner which reduces an amount of an eddy generated in an outlet or prevents generation of the eddy, to increase a flow rate of discharged air and reduce the generation of noise. The air conditioner includes an indoor air inlet and an indoor air outlet formed in a main body, an air blast fan to inhale indoor air through the indoor air inlet and to discharge the indoor air through the indoor air outlet, and at least one partition to reduce an amount of an eddy generated in the indoor air outlet or to prevent generation of the eddy. The at least one partition is installed on a separation plate that separates from each other a suction channel to inhale the indoor air and a discharge channel to discharge the indoor air.

A pipe fixing device comprising a plurality of pipes, for conducting liquid or gas, arranged to cross each other, and a fixing member for fixing the plurality of pipes. The fixing member comprises a plurality of pipe fixing bores, and a plurality of fitting bores for the fitting of bands used to tighten the pipes. The present invention can secure not only easy insertion of the pipes arranged to cross each other, but also enhancement in a coupling force of the pipes through the use of the tightening bands, resulting in stable and reliable fixation of the pipes.
摘要:
An air purifier and a method for controlling the same, where the air purifier has a uniformly high air-purifying efficiency throughout an overall indoor space having a complicated structure or broad dimensions. The air purifier includes a main body including an air-purifying filter; and a transport unit adapted to move the main body about a cleaning area. The method for controlling the air purifier includes: detecting a pollution level in a cleaning area; comparing the detected pollution level to a first reference value; determining which of a moving purification and a stopped purification is required based on the comparison; performing the stopped purification while the air purifier remains at a first location in the cleaning area when the stopped purification is required; and performing the moving purification while moving the air purifier about the cleaning area when the moving purification is required.

The present invention is related to a method for controlling data transmission in a wireless network system including a plurality of nodes. In accordance with the present invention, a duty cycle of a buffer of a node is configured to be adjusted according to a threshold value and a priority of a data to improve energy efficiency according to a variation of a network traffic, guarantee a prioritized transmission of an emergency data, prevent exclusive use of transmission medium by a certain node, and maximize a packet process rate.
摘要:
In order to solve a problem of an existing ARQ scheme using a fixed retransmission persistence, the present invention provides a method of dynamically managing a retransmission persistence of an ARQ according to an amount of data stored in a buffer of the ARQ, or according to time (transmission delay time) until data frame inputted from a buffer input terminal of a transmission node receives an ACK signal from a receiving node. That is, when an amount of data waiting the transmission at the buffer of the transmission terminal of the ARQ is small, a high persistence is allowed, and when the amount of data is large, only a relatively smaller persistence is allowed. Especially, when the amount of data stored in the buffer of the ARQ exceeds a congestion threshold, a retransmission is not allowed. The amount of traffic imposed on the ARQ is based on the amount of data stored in the buffer, and the number of retransmissions for one frame is adjusted in inverse proportion to the amount of data stored in the buffer.
