In the case of cleaning, the stick part 3 is configured to be able to tilt backward while the bottom surface side of the floor suction tool 31 is in contact with the surface to be cleaned.
[0019]
In addition, an air intake pipe 34 containing dust from the floor suction tool 31 is formed inside the lower part of the stick part 3, and communicates with the intake pipe 34 so that the tip of the hose 2 is connected to the lower side surface of the stick part 3. An insertion port 35 for detachably inserting the suction cylinder 21 is formed. The outside of the intake pipe 34 communicates with a connection port 36 to which an exhaust cylinder 15 formed on the lower front side of the stick portion 3 and protruding from the lower rear side of the cleaner body 1 is inserted and connected. An exhaust gas recirculation path 37 that recirculates part of the exhaust air from the electric blower 11 is formed at the suction port 311 of the floor suction tool 31.
[0020]
The vacuum cleaner main body 1 has a handle 14 formed on the upper part of the dust collecting part 12, and the exhaust cylinder 15 formed so as to protrude toward the lower back side of the vacuum cleaner main body 1. After being inserted into the reflux path connecting port 36 formed on the lower front side, the upper back side of the cleaner body 1 is attached to the front side of the corresponding stick portion 3 with a clamp (not shown). It can be removed by releasing the locked state by a button operation or the like, and can be easily detached. Here, the exhaust cylinder 15 and the return path connection port 36 constitute an exhaust return path connection portion, and also have a positioning function and a support function for the cleaner body 1 when the cleaner body 1 is attached to the stick portion 3. Therefore, it is necessary to have a certain strength.
[0021]
In addition, the dust collector 12 has a handle 14 formed on its upper part, and engages a lower portion on the front side of the dust collector 12 with an engaging portion (not shown) formed on the cleaner body 1 side. From the above, the clamp 142 formed integrally with the button 141 provided on the hand-held handle 14 is attached to the locking portion 16 on the cleaner body 1 side, and the locking state of the clamp 142 is changed to the spring 143. It can be removed by depressing and releasing the button 141 against the urging force.
[0022]
That is, the hand-held handle 14 of the cleaner body 1 in the present embodiment functions as a hand-held hand of the cleaner body 1 and also functions as a hand-held hand of the dust collector 12, and the dust collector 12 serves as the cleaner body 1. In combination with the upper part of the dust collecting part 12, the dust collecting part 12 can be easily attached and detached and garbage can be disposed of.
[0023]
In the above configuration, the flow of intake and exhaust during use as a normal vertical vacuum cleaner is as shown by arrows in FIG. That is, when the electric blower 11 is driven, the air sucked together with the dust from the suction port 311 of the floor suction tool 31 passes through the suction pipe 34 in the stick portion 3 and passes through the hose insertion port 35. 2 passes through the inside of the vacuum cleaner main body 1 and is sucked into the cyclone type dust collecting part 12.
[0024]
The air from which the dust is removed in the cyclone type dust collecting section 12 is sucked into the blower 112 of the electric blower 11 and further discharged after cooling the motor 111. A part of the exhaust discharged from the electric blower 11 is returned to the floor suction tool 31 from the exhaust pipe 15 on the lower rear side of the cleaner body 1 through the reflux path connection port 36 and the reflux path 37, and the suction port 311. The dust attached to the carpet or the like can be efficiently sucked by being sprayed on the surface to be cleaned such as the carpet.
[0025]
The remainder of the exhaust from the electric blower 11 is blown to the cord reel 13 through the power cord cooling flow path 17, and after cooling the power cord 131 wound on the cord reel 13, It is discharged to the outside from the formed exhaust hole (not shown).
[0026]
On the other hand, when cleaning the underside of the bed or the like, the cleaner main body 1 is in the way and cannot be cleaned with the stick 3 attached to the stick 3. Therefore, the handheld handle 14 is held with one hand. As shown in FIG. 4, the machine body 1 is removed from the stick portion 3, and the hose 2 is left attached to the stick portion 3. Then, while holding the grip portion 321 of the operation handle 32 of the stick portion 3 from which the vacuum cleaner main body 1 is removed with the other hand, the floor suction tool 31 is inserted below the bed while the stick portion 3 is tilted backward. By doing so, cleaning can be performed easily. At this time, the vacuum cleaner main body 1 has the heaviest electric blower 11 disposed at the bottom as described above, and the center of gravity of the vacuum cleaner main body 1 is lowered. Since the cleaner body 1 held by the upper hand-held handle 14 is stable during carrying by cleaning, the usability when the cleaner body 1 is removed and used is improved. Further, during such cleaning, there is a case where the cleaner body 1 is temporarily placed on the floor surface in order to move an object on the surface to be cleaned, but the cleaner body 1 as in this embodiment. Even if the outer periphery of the bottom surface is formed in a circular arc shape as shown in the figure for the purpose of improving the appearance, the center of gravity is low and it does not fall down.
[0027]
