Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vacuum cleaner for use in general households.

Structure of the conventional example and its problems In Figures 1 to 4, 1 is the bottom of the main body case that houses the electric blower 2, and a wall 3 is provided from the bottom of the main case 1 in a direction substantially perpendicular to the electric blower 2. . Reference numeral 4 makes an airtight connection between the wall 3 and the electric blower 2 in front of a support rubber fitted to the fan case part 5 of the electric blower 2, and is made of an elastic material such as urethane rubber. In order to improve the suction performance of the electric blower 2, the fan case portion 5 has a substantially conical suction portion 6 protruding therefrom.

A lattice section 7 is formed on the wall 3, and a filter frame 9 provided with a secondary filter 8 is secured to the lattice section 7 by claws 10 on the front side of the lattice section 7. At the upper end of the wall 3, there is a
A gasket 12 is provided to air-tight the main body case top 11. 13 is a rib body provided to serve as a guide when the gasket 12 is inserted and to prevent the wall 3 from falling forward due to the vacuum pressure of the electric blower 2, and is fitted with the front wall 14 of the upper body case 11. There is.

In the above configuration, when the electric blower 2 with the support rubber front 4 inserted is vertically inserted into the lower body case 1 as in the third case, the claw 1 of the filter frame 9
0 or the rib body 13 provided on the wall 3, which not only makes it very difficult to insert, but also turns over the support rubber front 4 inserted in the fan case 5, making the care tight between the electric blower 2 and the wall 3. becomes incomplete,
It may also cause performance deterioration.

Further, as shown in FIG. 4, if the electric blower 2 is inserted at an angle without hitting the rib body 13, the support rubber front 4 will also roll up, causing the above-mentioned problem. In addition, since the electric blower 2 is installed via the elastic support rubber front 4, if the main body is dropped from the front side, the electric blower 2
Due to its own weight, the support rubber front 4 is compressed and the intake part 6 hits the wall 3, damaging the lattice part 7.
It is necessary to provide a large gap between the wall 3 and the intake section 6. For this reason, it is necessary to increase the L dimension of the support rubber front 4 in FIG. 3, which further increases the problems such as difficult assembly and incomplete air tightness described in the previous section.

OBJECTS OF THE INVENTION The present invention solves the conventional drawbacks and provides a highly productive and stable electric cleaning method.

Composition of the Invention The present invention has an electric blower installed horizontally inside the main body case, which is opened at the top and has a dust collection section formed on the front suction side thereof, and a dust storage section that opens and closes the opening of the dust collection section. The lid, the upper part of the main body case that closes the open part corresponding to the above-mentioned electric blower under the main body case, and the above-mentioned electric blower provided through support rubber, respectively, are protruding from the inner surface of the main case below and the main case. A partition wall that elastically supports the blower, a ventilation lattice portion formed on the partition wall that supports the front side of the electric blower wall and protrudes from below the main body case, and a lattice portion that is latched to the rear edge through the lattice portion. and a filter frame holding a secondary filter, and a ring-shaped rib body is formed to protrude from the rear surface of the bulkhead under the main case having the lattice part, surrounding the lattice part. The front support rubber is in elastic contact with the tip thereof, and the height of the rib body is set higher than the rearward protrusion of the pawl and the other rearward protrusion of the partition wall having the lattice portion.

Therefore, when installing the electric blower, when moving the front support rubber downward along the rib body,
There is no longer anything that can hit the support rubber.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In Figures 5 to 7, 20 is under the main case,
A dust collection section 23 for storing a paper bag 22 is provided on the front side of the partition wall 21, and an electric blower 24 is provided on the rear side. A dust storage lid 2 is provided at the opening of the dust storage section 23.
5 are arranged. The front side of the dust storage lid 25 is locked with a buckle 27 that is rotatably fixed to the intake port cover 26 and the lower body case 20, and is hooked with a claw 28. The suction portion 30 of the fan case portion 29 of the electric blower 24 protrudes in a substantially conical shape in order to improve the suction performance of the electric blower 24.
A support rubber front 31 molded from an elastic material such as urethane rubber is inserted into the outer periphery of the fan case portion 29, and is in contact with a rib body 32 formed in a ring shape on the partition wall 21. 21 and the electric blower 24 are air-tight. A lattice portion 33 is formed in the partition wall 21 , and a filter frame 35 equipped with a secondary filter 34 is attached to the lattice portion 33 by claws 36 on the front side of the lattice portion 33 .
It is locked to. A gasket 38 is provided at the upper end of the partition wall 21 to air-tight the lower body case 20 and the upper body case 37. Also, 3
The rib 9 serves as a guide when the gasket 38 is inserted and to prevent the bulkhead 21 from falling forward due to the vacuum pressure of the electric blower 24. ing. The rear part of the electric blower 24 is connected to the rear partition wall 4 of the main body case upper 37 that covers the rear part 42 of the lower main body ace 20 and the upper part of the electric blower 24 via the support rubber rear 41.
It is clamped and fixed with 3. Above main body case top 3
On the top surface of 7, a gap nozzle 44 and a shelf nozzle 45 are installed.
A storage lid 4 is installed to cover the top of the storage lid.
6 are arranged. On the rear side of the storage lid 46,
A hinge portion 47 is provided so that the storage lid 46 is rotatably fixed to the main body case top 37. 4
8 is the front wheel and 49 is the rear wheel.

In the above configuration, as shown by the arrow in Figure 7,
When inserting the electric blower 24 into the lower body case 20, the ring-shaped rib body 32 protrudes from the claws 36 of the filter frame 35 and the ribs 39 at the upper end of the partition wall 21, so there is no obstruction in the insertion direction. , along the tip of the rib body 32, support rubber front 31
By inserting the air blower, not only can the electric blower 24 be smoothly inserted, but the air tightness will not be incomplete due to the support rubber front 31 turning over, and the quality can be guaranteed. Furthermore, when the main body is dropped from the front side as explained in the conventional example, the support rubber front 31 is compressed by the electric blower's own weight, and the intake part 30 of the fan case part 29 and the lattice part 33 come into contact with each other. Regarding the damage of the part 33, by adjusting the height H of the rib body 32 shown in FIG. 7, it is possible to freely reduce _L1 in order to reduce the compression of the support rubber front 31. There is no possibility that the case branch 33 will be damaged. Further, by forming the ring-shaped rib body 32 on the partition wall 21, the partition wall 21
The rigidity and strength of the material itself will also be improved.

Effects of the Invention As described above, by forming the ring-shaped rib body on the electric blower front wall of the present invention, the assemblability of the electric blower is improved.

Reliably guarantees air titer performance before the support rubber.

Prevents damage to the main unit due to falling of the main unit.

It has such effects and is of great value.
