Abstract: A clothes dryer including a cabinet including an inlet and a base; a drum inside the cabinet, a support frame including a front support frame supporting a front end portion of the drum, and having a laundry inlet, and a rear support frame supporting a rear end portion of the drum; a blow fan below the front support frame; and a guide portion behind the blow fan, and connected with the blow fan. The blow fan and the guide portion may be configured so that the blow fan is operable to move outside air to inside of the cabinet, and the guide portion guides a first portion of the outside air moved inside of the cabinet by the blow fan toward a gap between the drum and the front support frame to dry air leaking from between the drum and the front support frame.

Abstract: A dryer includes a cabinet, a drum installed in the cabinet and having an inlet through which air is introduced and an outlet through which air is discharged, a heat exchanger configured to remove moisture of the air discharged through the outlet and increase a temperature of the air, a fan installed between the outlet and the heat exchanger and configured to guide the air discharged through the outlet to be introduced into the heat exchanger, a blowing passage connecting the fan to the heat exchanger such that the air discharged through the fan is introduced into the heat exchanger after being bent at 90 degrees, and a vane installed perpendicular to a bottom surface of the blowing passage and disposed at a portion in the blowing passage in which the air introduced into the heat exchanger has a highest flow rate.

Abstract: A transmission period determination method, etc. capable of setting IPT transmission period by using general-purpose wireless modules and existing drivers is provided. A wireless communication system is a wireless backhaul. A route is established from a core node to a slave node. The core node assigns a specified transmission period and transmits a plurality of training packets to the slave node. The slave node transmits, to a transmission period determination device, the number of training packets received first and last and the number of training packets received without overlap. An estimation unit estimates a training time, the time for the slave node to receive the training packets. A calculation unit calculates a training metric candidate. An updating unit compares the values of the current training metric and the training metric candidate to determine the IPT transmission period.

Abstract: Provided are a communication system and the like capable of making a stable relay route even when a propagation channel is fluctuated by the fluctuation of RSSI. For making a tree-type communication route whose root is a core node, each slave node, after the reception of the latest reset routing packet from a node, judges if the transmission source node should be the parent of the tree-type structure based on the sequential average of the reception power of n routing packets received from the same transmission source node. As the reception power is log-normally distributed in general, an asymptotically stable relay route can be obtained, especially by using the sequential average.
