Abstract

PURPOSE:To obtain the titled device capable of performing the quick dust collection and the purification for a long period by providing a switch by which a blower is changed over to 'strong' (high) in the initial period of the timer operation actuating in a selection time of the time-velocity control of the blowing and changed over to 'weak' (low) after the elapse of the preset time. CONSTITUTION:A changeover switch selecting both the velocity control and the time-velocity control of an electromotive blower by which an air fow is formed through a dust collection part is provided. Also a timer actuating for a specified time in a selection time of the time-velocity control is provided. IN the initial period of the timer operation in the selection time of the time- velocity control, the switch is changed over to 'strong' operation of the electromotive blower. Also a switch body changing over it to 'weak' operation after the elapse of 20min preset time is provided. Therefore in 'a good-night operation' or the like, after performing quickly the dust collection 'strong' operation, the dust being increased can be collected by 'weak' operation for a long period.

(1) Prior Art As a technology prior to the present invention, there is an air purifying device described in Japanese Patent Application Laid-Open No. 60-29531.
Although speed control is carried out for "strong" and "weak" driving,
It only has a continuous operation function. Therefore, if you go to sleep with the mode set to "Strong", the sound of the fan will cause you to fall asleep, and if you go to sleep with the mode set to "Strong", the sound of the fan will be small, but the air will be blown away until you fall asleep. It was not possible to smoothly collect the dust that was floating in the air. As a result, it may be possible to set up a timer to control the time, but if the operation is stopped after a certain period of time, the dust that scatters from the futon as it moves while sleeping increases with time. Then, there was an issue.
