Document Type and Number:
Japanese Patent JPS6486925
Kind Code:
A
Abstract:
PURPOSE: To automatically travel a cleaner in the pulling direction of a sucking hose without requiring any power for moving it by providing a means for detecting the deriving direction of the sucking hose from a main body, a means for controlling a steering a driving means, and a detecting means for detecting the pulling power of the sucking hose. CONSTITUTION: When an operator moves forward away from a main body 1 and pulls the sucking hoes 6 during cleaning, a tension detection stand 5C is reclined forward, a tension transmission plate 5D is moved with this reclining, a microswitch 7 is turned on, a driving motor 13 is operated and a main body 1 is traveled. At such a time, a steering motor 10 is operated by rotary volumes 8 and 11 and a differential amplifier 17 corresponding to the deriving direction of the hose 6 and since steering and driving wheels 14 are turned toward the deriving direction of the hose 6, the main body 1 is traveled in the deriving direction of the hose 6. Thus, a high-operability self-traveling cleaner can be provided for automatically moving the main body 1 in the pulling direction of the hose without requiring any power while using the motor 10 for both steering and driving.
