The switching from the contacts b to a is performed by removing the plug connector 28 from the pin member 32. Can be automatically switched by operating to the forward position. A main switch 33 for controlling the motor 10 is provided on the same path. In the drawing, reference numeral 35 indicates an AC power supply.

This embodiment has the above configuration.
Each vacuum cleaner is used as follows. For example, if you want to take full advantage of the powerful dust collection performance such as cleaning the floor,
The cleaner body 4 is attached to the cleaner holder 2 of the main body case 1 as a stick-type vacuum cleaner. Further, the plug connector 28 of the cord 27 connected to the AC power supply is inserted into the connector hole 29 of the handle portion 14 and connected to the plug connector 30 (see FIG. 5). Then, the contact a of the microswitch 31
Is switched to b, and when the main switch 33 is pressed, the AC voltage from the AC power supply is applied to the motor 10 and the motor 1
0 drives the electric blower 9 under a stable AC voltage. Thus, in the present embodiment, the powerful dust collecting performance of the stick-type vacuum cleaner can be sufficiently exhibited.

Further, for example, as in the case of the above-described embodiment, a small-sized vacuum cleaner utilizing a powerful dust collecting performance is used, for example, in a typical case where foreign matter attached to a filter of an air conditioner is removed. It is also possible to use. In this case, the cleaner main body 4 is detached from the cleaner holding portion 2 of the main body case 1, and is used as a small-sized vacuum cleaner by gripping the handle portion 14 with a hand. At this time, of course, the plug connector 28 of the cord 27 connected to the AC power supply is inserted into the connector hole 29 of the handle portion 14 and connected to the plug connector 30 (FIG. 6).
reference). Then, when the contact a of the microswitch 31 is switched to b and the main switch 33 is pressed, an AC voltage from the AC power supply is applied to the motor 10. As a result, the motor 10 drives the electric blower 9 under a stable AC voltage simultaneously with the stick-type vacuum cleaner.

In order to be able to use such a small vacuum cleaner with high operability while maintaining good operability, the cord 27 must be connected in the best possible manner. Can be For example, if it is connected to the body of the cleaner body 4, the cord 27 will be in the way during cleaning,
This may hinder efficient work, such as having to work while pulling it by hand. On the other hand, in the case of the present embodiment, the cord 27 is connected to the end of the handle 14 of the cleaner main body 4 and pulled out from the opening 34 of the main body case 1, so that the cord 27 does not get in the way during cleaning. Work can be performed efficiently.

The manner in which the cord 27 is connected to the handle portion 14 can eliminate problems such as the cord 27 being entangled near the suction port 16 even when used as a stick-type vacuum cleaner.

The cord 27 is not connected to the handle 14 (see FIG. 1). At this time, the contact a of the microswitch 31 remains connected, and when the main switch 33 is pressed, the DC voltage from the storage battery 12 is applied to the motor 10. The DC voltage of the storage battery 12 is an adjusted value, and the motor 10 drives the electric blower 9 at a predetermined speed. In this manner, the cleaning can be performed while the noise due to the direct current is lacking, but the noise is noisy.

Further, it is also possible to use the apparatus as a small vacuum cleaner. The vacuum cleaner main body 4 is detached from the main body case 1 so as to be easily handled as a small vacuum cleaner, and the grip 14 is held and used. The cord 27 is not connected to the handle 14 (see FIG. 7). At this time, the DC voltage from the storage battery 12 is applied to the motor 10 with the contact a of the microswitch 31 connected. This operation is not powerful, but is primarily intended for instant cleaning, which is sufficient to draw in relatively light debris. Thus, in the present embodiment, good operability required for a small-sized vacuum cleaner can be always maintained.

Further, according to the present embodiment, the switching of the power supply in the motor control circuit is automatically performed by the micro switch 31, so that the user does not make an erroneous operation.

Further, the operations performed for controlling the motor 10 are only the opening and closing of the main switch 33, and there is no need to consciously switch the power supply in the motor control circuit. Never do.

[0026]

As described above, according to the first aspect of the present invention, a strong dust collecting performance is utilized in a required scene, and a noise which is noisy depending on the situation is eliminated to provide a stick-type vacuum cleaner. In addition, it can be used as a small vacuum cleaner while taking advantage of its powerful dust collection performance when required and maintaining good operability depending on the situation.

Further, according to the second aspect of the present invention, the power supply of the motor control circuit can be automatically switched without intentionally operating the switch, and erroneous operation can be eliminated.

Further, according to the third aspect of the present invention, the cord is hardly obstructed during cleaning, and the work can be efficiently performed.
