Description of the Related Art At present, the mainstream of domestic vacuum cleaners is a so-called cylinder-type vacuum cleaner in which a cleaning hose having a suction nozzle is derived from a vacuum cleaner body having an electric blower, and a power supply is also derived from the main body. A household AC power supply is used with a cord. On the other hand, so-called upright type vacuum cleaners, in which a cleaner body and a suction nozzle are integrated and a rotary brush is provided in the suction nozzle portion, are often used in Europe and the United States where carpet cleaning is frequently performed. Some vacuum cleaners of this type improve the operability by rotating a roller provided at the bottom of the suction nozzle with a motor so that the cleaner can run on its own.

いて来させることができるものである。Operation The operation of the first means is as follows. That is, when the cleaning hose is pulled, the pulling force detecting means detects this and moves the driving means. At this time, since the direction of the driving means is directed to the direction of the cleaning hose by the direction changing means, the cleaner body moves in the direction of the cleaning hose. Since the pulling force detecting means has a switch structure energized by a magnet, it operates reliably when a certain pulling force is applied at all times, so that the operability is good, and the vacuum cleaner body needs more than a certain pulling force. It can follow the operator without the need.

The basic operation is the same as that of the first means, except that a movement control means is provided, and after the pulling force detecting means detects the pulling force of the cleaning hose, the driving means is automatically moved for a certain distance to move the cleaner body. Can be done. For this reason, if only a certain pulling force is applied at the beginning of the operation of the cleaner body, the constant pulling force that was always required by the first means is no longer required by using the second means, and the operability is further improved. It realizes a traveling vacuum cleaner.

FIG. 2 shows the cleaning hose mount 17 in a state where the cleaning hose 18 is not pulled, and FIG. 3 shows the cleaning hose mount 17 in a state where the cleaning hose 18 is pulled. In the figure, the cleaning hose mounting base
17 is provided with a rotating ring 23 which is rotatable as indicated by an arrow B in accordance with the movement of the cleaning hose 18 in the rotating direction. The connecting hose 16 is fixed to the rotating ring 23. Also, the cleaning hose mount 17 is supported at the fulcrum as described above.
It is supported by 19, and a metal piece 24 is provided at the other end. Reference numeral 25 denotes a magnet, which attracts the metal piece 24 to urge the movement of the cleaning hose mount 17 in the direction of arrow A. or,
The configuration is such that the movement of the cleaning hose mount 17 is restricted at the tip of the main body 1, and the movement of the arrow A is performed between the main body 1 and the magnet 25. The cleaning hose mount 17, the magnet 25 and the switch 20 constitute a tensile force detecting means 26.

れた方向に車輪７は常に向けられることになる。Next, the operation of this configuration will be described. Cleaning hose
In a state in which 18 is not pulled (FIG. 2), the metal piece 24 is attracted by the magnet 25, the position of the cleaning hose mounting base 17 is lowered in the direction of arrow A, and the switch 20 is turned on.
Next, when the cleaning hose 18 is pulled (FIG. 3), the metal piece
24 comes off magnet 25 and cleaning hose mount 17
Rises in the direction of arrow A, and moves to a position restricted by the main body 1. At this time, the switch 20 is turned off, and it is detected that the cleaning hose 18 has been pulled.
At this time, the relationship between the distance between the magnet 25 and the metal piece 24 and the tensile force is as shown in FIG. 4. In the case where the magnet 25 is used, the tensile force decreases as the metal piece 24 moves away from the magnet 25. , 27. For this reason, when the cleaning hose 18 is provided with a maximum tensile force of C, a tensile force detecting means 26 which operates inertially can be realized.
If a coil spring or the like is used instead of the magnet 25 (not shown), the correlation becomes 28,
When the cleaning hose 18 is pulled, the pulling force continues to increase, and the pulling force is detected only at the operation stroke. For this reason, the operation feel is slightly heavy and awkward. As shown in FIGS. 2 and 3, when the cleaning hose 18 is moved in the direction of arrow B by the rotatable ring 23 rotatably formed on the cleaning hose mounting base 17, it is detachably connected. The rotating ring 23 moves in the same manner, and the connecting hose 16 connected to the rotating ring 23 is moved to transmit the movement of the cleaning hose 18 to the direction changing means 15. Therefore, as shown in FIG. 1, the wheel 7 is always directed in the direction in which the cleaning hose 18 is pulled out.

The electric blower 4 connected in series with the switch 29 is connected to the battery 22, and the switch 22 and the resistor 30 of the tensile force detecting means 26 are also connected to the battery 22.
Are connected. A movement control means 21 is connected to the battery 22, and a voltage at a connection point D between the switch 20 and the resistor 30 and a signal from the rotary encoder 8A are connected to the movement control means 21 as inputs. The movement control means 21 outputs an output to the driving means 8.

除機が実現できる。The operation of the control circuit configured as described above will be described with reference to FIG. The switch 29 turns on and off the electric blower 4. When the cleaning hose 18 is pulled, the switch 20 of the pulling force detecting means 26 is turned off, and the voltage D input to the movement control means 21 changes from High to Low. The movement control means 21 moves the driving means 8 by catching the edge of the voltage change from High to Low. Drive means 8
Moves, the rotary encoder 8A emits a pulse. This pulse is also input to the movement control means 21. When the pulses are counted by a predetermined number, the movement control means 21 stops the driving means 8. Since the number of pulses of the rotary encoder 8A is proportional to the rotation speed of the shaft of the motor as the driving means 8 and the rotation speed of the wheels 7, it is proportional to the distance.
Therefore, moving the driving means 8 until the number of pulses reaches a predetermined number moves a certain distance. In this way, the main body 1 moves by a certain distance when the cleaning hose 18 is pulled. Further, as described above, since the direction of the wheel 7 is oriented in the direction in which the cleaning hose 18 is pulled by the direction changing means 15, a vacuum cleaner that follows the direction in which the user pulls can be realized.

Further, in the second means, when the pulling force detecting means detects the pulling force of the cleaning hose, the moving control means moves the fixed distance by a certain distance. Since a vacuum cleaner can be realized and it moves accurately by a certain distance, the same operation feeling can always be obtained, and a truly easy-to-use self-propelled vacuum cleaner can be provided.
