Installation In's, as shown in FIG. 8 (a), since it is possible to open the lid 60 upwards, the sum of the space W between the width when the width W ₁ and human base 70 is slightly bent waist ₂ , it can be installed in a place much smaller than the installation space of the conventional vacuum cleaner main body 100 shown in FIG. For this reason, the degree of freedom of installation can be greatly expanded.

First, a dust suction hose having a suction tool is connected to a connection port of a piping pipe provided indoors, and a hand switch (neither is shown) is turned on. Thereby, the electric blower 2
5, the electric blower 25 rotates according to the control of the power control unit 35, and the suction tool starts to collect dust.

The air containing dust sucked from the suction tool is
The dust is sucked from the dust suction hose and the piping pipe 51 into the dust collection filter 54 through the suction hose 50, the connecting pipe 44, and the suction hole 46 of the cleaner body 1. At this time, the dust collection filter 5
4 is in close contact with the inner wall of the dust collecting case 10 via the rack tray 52, so that it is possible to prevent a reduction in dust absorbing power due to a decrease in the air passage.

The air containing the sucked dust is separated into dust and air in the dust filter 54, and the dust is accumulated in the dust filter 54. On the other hand, the air filtered by the dust filter 54 is further filtered from the small holes 16 of the motor cover 15 through the secondary filter 17, and is sent from the electric blower 25 into the duct 20 through the opening 34 of the cylindrical body 33. Then, it flows through the exhaust passage 23 to cool the power control unit 35, is sent into the main body case 2 from the exhaust unit 24, and is discharged out of the machine through the exhaust port 6 provided in the substrate 5.

During this time, since the electric blower 25 rotates at a high speed of 30,000 or more per minute, noise and vibration are generated. However, the noise is caused by the electric blower 25 being connected to the bottom plate 1 of the dust collecting case 10.
1, a substantially spiral duct 20, a sound deadening material 23 a attached to an inner wall of the duct 20, a secondary filter 17 provided on the motor cover 15, a cover plate 61, and a cover 62. And a cover 6 composed of a holding plate 64
Most of the sound is blocked by 0 or the like. Also, the vibration
First and second vibration insulators 31 and 3 holding electric blower 25
2 and is reduced.

When the dust has fully accumulated in the dust collecting filter 54, the latch set 66 is released and the lid 60 is moved to the hinge 6
5 is opened to a shaft, and fixed at a desired angle by a stay 67. Then, after the latch mechanism 47 of the mounting base 45 is loosened to remove the mounting plate 55 of the dust collecting filter 54, as shown in FIG. Take out of the machine and discard. At this time, as shown in FIG. 8A, the dust collection filter 54 can be easily taken out without strongly bending the body. Then, the mounting plate 55 of the spare new dust collecting filter 54a housed between the dust collecting case 10 and the rack tray 52 is attached to the mounting base 45 and set in the dust collecting case 10, and the lid body 60 is set. It is closed and locked by the latch set 66. At this time, a new dust filter is stored between the dust collecting case 10 and the rack tray 52.
Thereby, without losing the dust collection filter 54,
Further, the trouble of searching for the dust collecting filter 54 at the next replacement can be omitted.

If the dust collecting filter 54 is full of dust, or if the piping path is clogged by careless intrusion of excessive dust, the air volume of the electric blower 25 decreases. For this reason, the temperature of the electric components mounted on the printed circuit board 36 of the power control unit 35 rises sharply, and the radiation fins 37 also react sensitively to this and rise in temperature. The temperature rise of the heat radiation fin 37 is detected by the heat sensitive element 41 directly attached to the heat radiation fin 37, and the power supply to the electric blower 25 is cut off or reduced. Therefore,
After turning off the hand switch, replace the dust collection filter 54 or remove clogged dust in the piping route, etc.
When the hand switch is turned on again, the suction function is restored in a normal state.

When checking or repairing the electric blower 25 and the power control unit 35, which are the main electric parts, first, the lid 60 is opened and the rack tray 52 and the dust collection filter 54 are opened.
Is taken out of the machine, the partition plate 13 is removed, and the machine is taken out of the machine.
When the cylindrical body 33 is removed from the bottom plate 11, the electric blower 25 can be easily taken out of the machine. When the mounting plate 38 is detached from the bottom plate 11, the power control unit 35 and the thermal element 41 together with the mounting plate 38 can be taken out from the opening 19 provided in the bottom plate 11.

A bottom portion of the opening portion 18a provided in the bottom plate 11 is a holding portion of the electric blower 25 attached to the outer periphery of the bottom surface, and has a substantially bottomed cylindrical shape.
An opening 29 is provided for insertion of an opening. Reference numeral 15a denotes an electric motor cover having a large number of small holes 16, and a cylindrical rib 15b having a smaller diameter than the opening 18a protrudes from a lower surface thereof, and is screwed to an upper surface of the bottom plate 15. In the present embodiment, the partition plate 13 and the cylindrical body 33 provided in the dust collecting case 10 in the first embodiment are omitted.

In the present embodiment as described above, the first vibration isolator 31 is interposed between the bottom of the holding portion 28 and the blower portion 26 of the electric blower 25, and the motor portion 27 is opened.
9 and inserted into the duct 20. Then, the second vibration isolator 32 is disposed on the outer periphery and part of the upper surface of the blower section 26, and the electric blower 25 is held by the first and second vibration isolator 31, 32 in a suspended state. Then, the motor cover 15a is positioned on the opening 18a of the bottom plate 11, the rib 15b is inserted into the opening 18a, and the motor cover 15a is brought into contact with the second vibration isolator 32 and screwed to the bottom plate 11.

The operation of the present embodiment is almost the same as that of the first embodiment, except that the partition plate 13 and the cylindrical body 33 are omitted, and the motor cover 15a is directly attached to the bottom plate 11, and the first and second embodiments are performed. As we tried to hold down the vibration insulators 31, 32,
The structure becomes simple. Also, the partition plate 13 and the cylindrical body 33
It is easy to take out the electric blower 25 and the power control unit 35 outside the machine, because there is no air blower.

Since the opening through which the coupled heat radiation fins pass is provided, the power control unit and the like can be installed in the duct by passing through the opening from inside the dust collecting case. Further, when the power control unit or the like is inspected or repaired, the work can be easily performed because the power control unit can be pulled out from the opening and taken out of the machine.

(6) A printed circuit board provided with a power control unit for controlling the electric blower in the duct of (2), (3) or (5), and a radiation fin integrally connected to the printed circuit board With the above arrangement, the heat-generating electric components mounted on the printed circuit board can be cooled by the strong wind of the exhaust gas passing through the duct, and the performance of the power control unit can be maintained.

(7) Since the printed circuit board of (6) is installed at right angles or inclined to the horizontal plane, the electric components mounted on the printed circuit board can be efficiently cooled, and condensed water is generated. Even if it adheres to the printed circuit board, it flows down along the surface, so that insulation failure does not occur.

(8) Since the heat-sensing element for detecting the abnormal overheating in the main body case and controlling the input of the electric blower is attached to the radiation fin of the above (6), the dust collecting filter becomes full, the piping path is clogged, etc. If the air volume decreases due to the air flow and the inside of the main body case becomes overheated due to the rise in the temperature of the electrical components mounted on the printed circuit board, this can be detected immediately and the input to the electric blower can be reduced or cut off. Can be detected early, and a failure can be prevented before it occurs.

(9) In the dust collecting case of (1), (2) or (3), a rack tray formed by bending a wire, provided with a handle and holding a dust collecting filter is accommodated. In addition, it is easy to take out a dust collection filter that is full, and at the time of cleaning, the dust collection filter is in close contact with the inner surface of the dust collection case, so that it is possible to prevent a reduction in dust absorption force due to a decrease in ventilation passages.

(10) Since a storage portion for storing the folded dust collection filter is provided between the peripheral wall of the dust collection case and the rack tray of (9), a new dust collection is provided every time the dust collection filter is replaced. By storing the filter, there is no danger of losing the dust collection filter, and the trouble of searching for the dust collection filter every time the filter is replaced can be omitted.
