Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a vacuum cleaner, and particularly to the structure of a vacuum cleaner body.

(Prior art) In a vacuum cleaner, in order to downsize the vacuum cleaner main body, a dust collection chamber is formed at the front of the vacuum cleaner main body, and this dust collection chamber is separated from the vacuum cleaner main body by a flat partition. There is a vacuum cleaner main body structure in which an electric blower and a power cord winding device are arranged in parallel on the left and right at the rear, making efficient use of the internal space of the vacuum cleaner main body.

By the way, recently, electric blowers have become smaller and it has become possible to make the vacuum cleaner itself even smaller.
Regarding the power cord winding device installed in parallel with the electric blower, the reel diameter has necessarily remained large because the cord length cannot be ensured if the diameter of the cord reel for winding the power cord is made small.

(Problems to be Solved by the Invention) As mentioned above, as electric blowers become smaller, it has become possible to make the vacuum cleaner itself even more compact. Since the cord reel diameter of the winding device remains large, the amount of rearward protrusion of the electric blower with respect to the flat bulkhead separating it from the dust collection chamber will be small, but the amount of rearward protrusion of the power cord winding device will be reduced. remains the same and is large, making it difficult to further downsize the vacuum cleaner body.

The present invention has been made in view of these points, and provides a vacuum cleaner that can further downsize the vacuum cleaner body even if the diameter of the cord reel is large to ensure the required cord length. The purpose is to

[Structure of the invention]

(Means for Solving the Problems) The present invention forms a dust collection chamber in the front part of a vacuum cleaner body, and an electric blower and a power cord are wrapped in the rear part of the vacuum cleaner body, which is separated from the dust collection chamber by a partition wall. In a vacuum cleaner in which winding devices are arranged in parallel on the left and right sides, the front end of the cord reel of the power cord winding device and the partition wall corresponding to the front end of the cord reel protrude toward the dust collection chamber. be.

(Function) In the present invention, the front end of the cord reel of the power cord winding device and the partition wall corresponding to the front end of the cord reel are made to protrude toward the dust collection chamber, thereby ensuring the required cord length. Even if the diameter of the reel is large, the amount of rearward protrusion of the power cord winding device is reduced, and the overall vacuum cleaner body can be made smaller.

6 and is held between a rib 17 protruding from the inside of the holding frame 16 and a frame member 18 attached to the front end of the holding frame 16.

The filter frame 15 has stepped portions 19 projecting outwardly on the left and right sides of the rear end of the holding frame portion 16, and a peripheral edge portion 20 formed to match the inner surface shape of the dust collection case 3.
An annular backing 21 is fitted into the ring. This backing 21 has a contact piece 22 that is in close contact with the inner circumferential surface of the dust collection chamber 4 and a contact piece 23 that is in close contact with the front surface of the partition wall 5, sealing the rear surface of the dust collection chamber 4, and the dust collection filter 12. The suction chamber 24 formed in the space between the partition wall 5 and the partition wall 5 is sealed.

The main body case 2 has an opening formed in the front, and the partition wall 5 is attached to the inside of the front surface thereof, and partition plates 31 and 32 project from the rear surface of the partition wall 5, and partition plates 33 and 33. 34, a blower chamber 35 and a cord reel chamber 36 are partitioned in parallel on the left and right.

The partition wall 5 has its peripheral edge fitted and inserted into the front opening of the main body case 2, and has mounting bosses 3 provided at a plurality of locations.
7 is fitted into a mounting boss 38 protruding from the main body case 2 and fixed by a screw 39, and a slit corresponding to the front surface of the blower chamber 35 communicates the suction chamber 24 and the blower chamber 35. A shaped ventilation hole 40 is formed, and an annular support piece 41 that supports the electric blower 6 is protruded around the rear surface of the ventilation hole 40, and a cord reel 48 (described later) is provided in correspondence with the front surface of the cord reel chamber 36. An arc-shaped protrusion 43 is formed that constitutes a recess 42 into which the front end of the front end enters.

Further, the electric blower 6 disposed in the blower room 35
The front end is an annular gasket 44 attached to the support piece 41 of the partition wall 5.
The rear end portion is supported via an elastic body 46 by a support piece 45 protruding from the inner surface of the main body case 2 .

Further, in the power cord winding device 7 disposed in the cord reel chamber 36, the reel shaft 47 is connected to the partition plate 31 of the partition wall 5.

Next, the operation of this embodiment will be explained.

The cord reel 48 of the power cord winding device 7 housed in the main body case 2 has a diameter larger than the length of the electric blower 6 in order to ensure the required cord length. The front end portion enters a recess 42 formed on the rear side of the protruding portion 43 of the partition wall 5 and protrudes from the flat front surface of the partition wall 5 toward the dust collection chamber 4 side. The amount of protrusion is smaller.

In this way, the cord reel 48 of the power cord winding device 7
Since the amount of rearward protrusion of the electric blower 6 can be reduced, the electric blower 6 can be made smaller and the length between the front surface of the partition wall 5 and the rear surface of the main body case 2 can be shortened compared to conventional ones, and the vacuum cleaner as a whole can be made smaller. The main body 1 can be made smaller, and
Since the protruding portion 43 of the partition wall 5 protruding toward the dust collection chamber 4 side protrudes into the suction chamber 24 between the dust collection filter 12 and the partition wall 5, the dust collection function is not impaired.

〔Effect of the invention〕

According to the present invention, the front end of the cord reel of the power cord winding device and the partition wall corresponding to the front end of the cord reel are made to protrude toward the dust collection chamber. Even if the diameter is large, the amount of rearward protrusion of this cord reel can be reduced, and the overall vacuum cleaner main body can be made smaller.
