Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a vacuum cleaner for use in general households.

BACKGROUND ART A conventional vacuum cleaner of this type has a structure as shown in FIGS. 6 and 7.

That is, the cylindrical retainer is raised from the lower part of the main case 53 and receives the front surface of the elastic support 52, which serves to prevent the vibrations of the blower 51 from being emitted outside as noise and prevent external shocks from being transmitted to the blower 51. A rib 54 is provided, a rib 56 that fits into the upper part of the main case 55, and a fitting claw 57 provided at the rear of the main case.

Problems to be solved by the invention However, with this kind of structure, the upper and lower parts of the main body case 55, 5
It is necessary to increase the strength of the resin itself in the direction of the fitting claw 57 that connects the parts 3 and the rib 56 that fits with the upper body case 55 disposed from the lower body case 53. In terms of technology, increasing the wall thickness and reinforcing ribs both increase the weight of the main body, which is a direction that goes against the current demand for a small and lightweight vacuum cleaner.

Means for Solving the Problems The technical means of the present invention for solving the above problems consists of a bottom part of the main body case which is divided into a dust collection chamber and a power chamber by a partition wall with suction holes formed therein, and a support made of an elastic body. The air blower is attached to the power chamber under the main body case through the body, the main body case covers the upper part of the power chamber, and the lid opens and closes the upper part of the dust collection chamber. Forms a cylindrical holding rib that the front support of the blower comes into contact with, and also has a supporting rib that projects upward and has a rear surface that is flush with the tip of the holding rib. On the other hand, there is a claw part that also serves as a rest part and that fits from the rear into a claw fitting hole formed on the rear surface under the main case.
Further, each of the support ribs has an inner wall in close contact with the front surface of the support rib at the front, and the front surface of the support rib is an inclined surface that becomes thinner at the top.

Effect The effect of this technical means is as follows.

That is, the elastic support disposed in the fan case of the blower can be easily removed by hand or the like, unlike press-fitting the elastic support body into the fan case of the blower. In such a fitted state, when setting under the main body case, the air tight part of the elastic support should ideally be flat, but due to the shape of the blower and the conditions during molding of the elastic support, it may be cylindrical. It is necessary to form a support rib, but at this time, by making the part where the elastic support is set under the main case as a flat part and protruding from the dividing surface under the main case, it is easy to insert the blower, and it is elastic. This prevents the support from turning over.

Embodiment Hereinafter, an embodiment of the present invention will be described based on the accompanying drawings. In Figures 1 and 2, 1 is a lower main body case with a dust suction chamber 2 with an upward opening on the front side and a built-in blower 4 for dust suction in the rear power chamber separated by a partition, and an upper main body case 5 is set. has been done.

A handle portion 6 is formed at the front end of the lower main body case 1, a moving roller 7 is attached to the rear portion, and a caster roller 8 is attached to the bottom surface.

The fan case 9 of the blower 4 is provided with a cylindrical support rib 11 on the front wall and a holding rib 12 protruding from the divided portion of the lower body case 1 via a support 10 made of an elastic material such as rubber. At the rear of the partition wall 3, a blower 4 is held via a support 14 by a rib 13 that stands up from the bottom 1 of the main body case.

Reference numeral 16 indicates a claw portion which is formed at the rear of the upper body case 5 and also serves as a rest portion, and is fitted from the rear into a claw fitting hole 15 provided at the rear surface of the lower body case 1 and is held.

Further, the front part of the upper body case 5 is fastened to the boss 17 of the lower body case 1 via screws 18.

Reference numeral 18 denotes a front cover whose upper end is integrally fixed with screws, which are fitted into holes with round bosses erected from the bottom 1 of the main body case. This front cover 18 has a connection hole 19 for connecting a hose, and an opening communicating with the connection hole 19 made of an elastic material such as rubber is provided between the front cover 18 and the lower main body case 1, and a gasket 20 is held therein under pressure.

Reference numeral 21 denotes a lid that covers the upper opening of the dust suction chamber 2, and a rear claw 23 is inserted into a hole 24 provided on the top 5 of the main body case. Further, a buckle 25 made of an elastic body provided on the lower 1 side of the main body case is engaged with the handle portion 22 formed on the front side. Reference numeral 26 is a dust collection bag that functions as a filter for capturing dust, and is integrally formed with a mouth frame 27 made of cardboard or the like by adhesive or the like. The lid 21 has a pointer 28 when the dust collection bag 26 is full of dust.
A display mechanism 29 for displaying the information is built-in.

Reference numeral 30 denotes a gasket that is press-fitted into a groove provided all around the upper end surface of the lower body case 1, and has a structure that is kept airtight by the lid 21.

A suction hole 31 is provided in the partition wall 3 of the dust suction chamber 2, and a secondary filter 32 made of non-woven fabric or the like is built-in, and ribs are planted from the bottom 1 of the main body case to prevent the dust collection bag from coming into close contact with the suction hole 31. There is.

In the above configuration, the blower 4 is provided with a support 10 that is inserted into the fan case 9 with rubber elastic force.
When inserting into the lower body case 1, the holding rib 11 forming a cylindrical shape on the partition wall 3 of the lower body case 1 and the support rib 1 protruding from the dividing part of the lower body case 1
It is inserted using the A side of 2 as a guide.

When setting the upper body case 5, set the claw part 16 provided from the upper body case 5 into the claw fitting hole 15 provided at the rear of the lower body case 1 as shown in FIG. Rotate. At this time, the support rib 12 protruding from the partition wall 3 of the lower body case 1
Setting is performed along the inclined surface 12' of the support rib 12, and after setting, the surface of the support rib 12 and the inner wall 5' on the main body case are in close contact.

Effects of the invention As described above, according to the invention, when a blower whose support is inserted into the fan case is set under the main case, the retaining rib surface protruding from the bulkhead acts as a guide, applying elastic force to the fan case. The support body inserted with a chisel does not turn over, and the support rib surface is more uniform than the retaining rib surface, making it easy to assemble since it is set on the cylindrical support rib. Also, due to the relationship between the hook-fitting direction on the main body case and the support rib surface protruding from the bulkhead, the support rib surface is in contact with the inner wall surface on the main case, so that the shock to the blower caused by dropping the package is prevented. This is the same effect as increasing the board thickness, and the claws fit in the direction in which the rigid body of the vacuum cleaner receives the shock when the vacuum cleaner is stood up, unless the claws crack.
The claw will never come off.

As described above, the present invention provides a lightweight product that is easy to assemble and can withstand impact forces without increasing the thickness of the resin.
