The AC circuit 53 includes a first changeover switch 5G that can be switched by the first switch button 14 between a pair of AC terminals 55, a first coil 57, the electric blower 2, and a second coil 58. are formed by connecting them in series.

Further, the DC power supply circuit 54 has a resistor 60 and a rechargeable battery 61 as a high-output DC power supply connected in series between a pair of DC terminals 59 and with the (-) end facing the resistor 60. This rechargeable electric it! ! Connect the (-) end of 61 to the second
The second changeover switch 62 is opened and closed by the switch m19.
and the first selector switch 56 to the middle part of the first coil 57, and the rechargeable
The (+) end of the pond 61 is connected to the middle portion of the second coil 58.

The in-support circuit section 52 also includes an AC power circuit 72 that supplies an alternating current from an external AC power source 71 as a high-output power source to the AC circuit 53 of the in-body circuit 51 via the electric cord 44; A charging circuit 73 receives an alternating current from the power source 11 and supplies a direct current charging current to the direct current power supply circuit 54 of the circuit 51 in the main body.

The AC power supply circuit 72 has a pair of AC power supply terminals 74 that are connected to the pair of AC terminals 55 of the AC circuit 53 when fitted to the fitting part 32 of the cleaning main body 1, and the charging circuit 73 has a transformer 75 connected to an AC power source 71, and two diodes 77.78 are connected in opposite directions to both ends of the secondary coil 7G of this transformer 75, and the two diodes 77.78 (- ) side charging terminal 79 is connected, and a (+) side charging terminal 79 is connected to an intermediate position of the secondary coil.

Next, the operation of the vacuum cleaner of this embodiment will be explained.

When using this vacuum cleaner to clean low places such as floors, the vacuum cleaner main body 1 is fitted into the fitting part 32 of the support 31.

When the main body 1 is fitted to the fitting part 32, each pair of AC terminals 55 of the internal circuit part 51 provided in the vacuum cleaner main body 1 is connected to the fitting part 32.
, and a pair of DC terminals 59 are connected to the pair of DC power supply circuits 74 and the pair of charging terminals of the in-support circuit section 52 provided on the support body 31, respectively, so that the AC circuit 53 and the AC power supply circuit 12 are connected to each other. is connected, and the DC power supply circuit 5
4 and the charging circuit 73 are connected.

Moreover, by fitting the pre-cleaning main body 1 into the fitting part 32, the second switch! 019 is pressed, the second selector switch 62 is turned off, and the DC power supply circuit 54 is opened.

Therefore, even if the first selector switch 56 is turned to the DC power supply circuit 54 side, the electric blower 2 will not operate. On the other hand, when the first selector switch 56 is turned on to the AC circuit 53 side, the electric blower 2 is operated by the AC power source 71 as a high output power source, so the high suction power necessary for cleaning carpets etc. is increased to 1! ?
can be done.

By the way, when the security iso body 1 is fitted into the fitting part 32, the charging circuit 73 and the rechargeable battery 61 of the DC power supply circuit 54 are connected, so that the rechargeable battery 61 is charged.

This charging is carried out between the AC power supply circuit 72 and the AC circuit 53.
Charging is carried out even while the electric kite transporter 2 is being operated using alternating current from the kite, so charging is efficient.

Next, when cleaning a slightly higher place such as the top of a table, the extension tube 33 of the support 31 is too long and difficult to clean.
1. Remove the wood removal main body 1 from the fitting part 32 of the support body 31. When the suspension body 1 is removed from the fitting part 32 of the support 31, the second switch button 19 protrudes and the second changeover switch 62 is turned on, so the rechargeable battery 61 can be used as a low-output DC power source. When the first changeover switch 56 is placed on the DC power supply circuit 54 side, the electric blower 2 is operated by the low-output rechargeable battery 61, so cleaning is performed in this state.

The suction force obtained at this time is weaker than when using a high-output AC power source as described above, but it is sufficient for cleaning simple areas such as table tops. In this case, the nozzle 23 is removed from the nozzle storage recess 24 and inserted into the suction port 21.

By the way, the electric circuit of the vacuum cleaner consists of an in-body circuit section 51 on the side of the cleaning plate main body 1 and an in-support circuit section 52 in the support body 31.
Since there is no charging transformer 75 or the like in the vacuum cleaner main body 1, the weight of the vacuum cleaner main body 1 itself is light, making the vacuum cleaner main body 1 easy to hold and cleaning.

After cleaning is completed, move the II4 main body 1 onto the support 31.
The entire wall surface 431. :The hook hole 41 is engaged with the provided third hook 42, and the main body of the electricity report, which is integrated with the support body and the main body of the noise reduction device, is 11) hung.

By the way, the electric cord 44 is attached to the first and second hooks 39.
．． This electrical cord 44 is wrapped around and stored in the
When using it again, the second hook 40 is rotatable, so if you turn the L-shaped bending direction inward, the electrical cord that was caught on the second hook 40 will be removed. 44 comes off all at once, so the cable can be removed more quickly than unwinding.

In this embodiment, a rechargeable battery 61 is used as a low-output power source, but a simple dry battery may also be used.

In addition, in this embodiment, two power sources, an AC power source 71 and a rechargeable battery 61, are used, but the rechargeable battery 61 is not provided and only the AC type 11171 is used, and the output can be adjusted high or low using a variable transformer. It may be changed. In this case, a variable transformer is provided in the cleaning tool body 1, an electric cord is connected to the variable transformer, and the second switch button 19 is connected to the variable transformer.
The output selector switch of this variable transformer is set to the body output side when the drawing/removal main body 1 is fitted into the fitting part 32 of the support 31, and the vacuum cleaner main body 1 is set to the fitting part 32 of the support 31. Switch to the high output side when removed from the

Further, in this embodiment, a second changeover switch 62 is provided,
When the drawing body 1 is removed from the fitting part 32, this second
The selector switch 62 is turned off, and the rechargeable electric ii! ! 6
1 cannot be used, but if this second changeover switch 62 is not provided, the vacuum cleaner main body 1 cannot be used.
When used by fitting into the first fitting portion 32, the selection by the first changeover switch 56 allows use of either AC or DC. Therefore, if the electric cord 44 is not long enough and can be operated with DC current from the DC' power supply circuit 54 even in a place where the suction port 34 of the support body 31 cannot reach, the electric cord 44 can be connected from an indoor outlet. You can clean it by removing it and going to hard-to-reach areas.

In addition, in this embodiment (when the suspension body 1 is removed from the fitting part 32, the AC Ichihara circuit 72 on the support body 31 side and the AC circuit 53 on the cleaning body 1 side are separated, Although the power supply circuit 541111IL cannot be used, if an electric cord with a new plug is connected to the AC circuit, it becomes possible to use AC current.

Furthermore, instead of the first selector switch 56, a ')&off switch 81 shown in FIG. 1 may be provided to close the AC circuit 53 and the DC power supply circuit 54 at the same time.

〔Effect of the invention〕

According to the present invention, for cleaning, the main body can be detached from the support body in 4 ways,
Depending on the place to be cleaned, it can be used either with the L-ya cleaning body attached to the support or with the cleaning body alone, making cleaning easier.

Also, when cleaning simple areas such as table tops, if the suction power is too strong, it will actually be difficult to clean, but if you remove the local dirt remover from the fitting part of the support and use it alone, the power output will be low. Since it is an output, the suction power is also moderately reduced, making it easy to clean simple areas such as table tops.
