Abstract

PURPOSE:To shorten the time for drying washing clothes by providing an alarm for ending drying of a synthetic fiber by means of a drying sensor. CONSTITUTION:A drying sensor 7 for synthetic fiber, located at the place where clothes 5 in a rotation drum 1 is frequently touched, detects the drying degree of the synthetic clothes among the clothes 5 composed of cotton and synthetic clothes. In short, the synthetic clothes can be dried up faster than the cotton clothes and it generates static electricity at the time of drying, this static electricity is detected by the sensor or an electrodes detection sensor detects the infinite electric resistance because the electric resistance becomes infinite when drying the synthetic clothes. When drying the synthetic clothes, the end of drying the synthetic clothes is reported by actuating an alarm 9 (voice or buzzer) by means of a controller 8. In this case, the synthetic clothes are taken out from the dryer, and the drying operation is further continued. When the cotton clothes is dried, a drying sensor 10 for cotton clothes detects the drying, and automatically ends the drying operation by the controller 8.

る。As shown in the figure, a dry sensor 7 for the synthetic clothes is provided in the rotating drum 1 at a place where the clothes 5 come into contact with the clothes. It is designed to detect. That is, the synthetic fiber clothing dries faster than cotton clothing, and the characteristic of synthetic fiber clothing is that static electricity is generated when it dries, so if this static electricity is detected by a sensor, or if the synthetic fiber clothing dries, the electrical resistance becomes infinite. This may be detected by an electrode type detection sensor. 8 is a controller that activates an alarm 9 (voice or buzzer) when the synthetic clothing dries,
Notify the completion of drying of synthetic clothing. Here, take out the synthetic clothes from the clothes dryer, then continue the drying operation,
When the cotton clothing dries, the drying sensor 10 for the cotton clothing detects the drying, and the controller 8 automatically ends the drying operation. When the dryness sensor 10 for cotton clothes approaches the end of drying, the exhaust gas temperature starts to rise. Therefore, by detecting this, the drying operation is automatically ended at the optimum time.

より報知器９を作動させればよい。FIG. 2 is a graph showing the static electricity generation condition of the clothes in the rotary drum 1. As shown in the figure, when the synthetic clothes become dry, the electrostatic voltage of the drying sensor 7 part draws a serrated curve. Since the temperature rises, the optimum point P is experimentally obtained, and the alarm 9 is operated by the controller 8.
Fig. 3 shows the change curve of the electric resistance of the electrode in the case of the electrode type detection sensor. The electric resistance increases as the synthetic clothing dries,
On the other hand, since cotton clothes have not dried yet, their electric resistance is low, and these two kinds of clothes randomly hit the drying sensor 7 parts and rise while drawing a sawtooth random curve as shown in the figure. After obtaining the information, the controller 8 may operate the alarm device 9.
