Description

[Detailed description of the invention] The present invention relates to a vacuum cleaner, and provides a dust collector installed in a dust collection box with a simple structure and low cost, and also makes it easy to engage and disengage. The purpose is to

In vacuum cleaners, it is necessary to dispose of the dust that has been sucked in, so a dust collection box is installed inside the vacuum cleaner body so that it can be attached or removed.

Further, a dust collector such as a filter is removably attached to this dust collection box, and the dust collection device is removed from the dust collection box when disposing of dust.

FIGS. 1 and 2 show a conventional structure for connecting and disengaging a dust collection box and a dust collector. The dust device main body 3 was designed to protrude forward of the frame 2, and the frame 3 was detachably engaged with the vicinity of the opening end of the dust collection box 4.

That is, the frame 2 of the dust collector 1 has a grip part 5 in the vertical direction at the center, and is housed inside the grip part 5 and a part thereof is exposed to the side of the grip part 5. A protrusion 1 is provided on the upper part of the swinging locking device 6, and the locking device 6 is a so-called PP.
The exposed portion 6A of the swing locking device 6 is supported by the grip portion 5 by the hinge mechanism 8, and the protrusion 1 is moved downward from the upper surface of the frame body 3 by gripping the exposed portion 6A of the swing locking device 6 together with the grip portion 5 as shown in FIG. In this state, the dust collector 1 is inserted into the dust collection box 4, and then the exposed portion 6A is released and the protrusion 7 is made to protrude upward from the upper surface of the frame 2, and at the same time, the protrusion γ is inserted into the dust collection box 4. box 4
It was engaged with an engagement hole 8 formed near the upper end of the opening.

When I left, I was doing the opposite.

However, with such a configuration, the number of parts increases, and as mentioned above, when using a PP hinge, it is difficult to manage the parts to make full use of its spring properties.
Since the grip portion 5 was provided in the vertical direction of the dust collector 1, it was not very convenient to use.

The present invention was devised in view of these drawbacks, and one embodiment of the invention will be described below with reference to the drawings.

The sweeper main body 10 has a lower casing 1 that can be divided into upper and lower parts.
1 and an upper casing 12, and a lower casing 11.
In the rear half of the front and rear partition walls 13A.

13B is formed, and an electric blower 1 is connected between the partition walls 13A and 13B via a breathable cylindrical soundproof plate 14, etc.
5 is built-in, and the electric blower 1 in the front partition wall 13A
A large number of through holes 16 are formed in the portion facing the suction surface 15A of 5.

Further, a dust collection box 17 is detachably attached to the front half of the lower casing 11, and the dust collection box 11 is open on the side of the blower 15, and a primary filter 18 and a secondary filter are provided in this open part. A filter 19 is attached.

As is clear from FIG. 4, the primary filter 18 includes a frame 20 whose bottom and rear portions are open and whose front and left and right sides are formed in a large lattice shape; It consists of a net-like material 21 disposed over both sides.

The secondary filter 19 also includes a frame 22 that is removably fitted into the frame 20 of the primary filter 17 from the rear thereof;
The frame body 22 of the secondary filter 18 consists of a corrugated filter medium 23 arranged vertically in the vertical direction at the suction opening of the frame body 22.
A gasket 24 is disposed on the outer periphery of the rear part, and a fixed frame 26 made of synthetic resin having a sliding hole 25 in the center is fixed.A rotary plate 27 and a large plate are mounted on the front and rear sides of the fixed frame 26, respectively. A diameter gear 28 is arranged, and both are interlocked and connected via protrusions 27A and 28A rotatably fitted into the sliding hole 25 of the fixed frame 26.

On the other hand, one diaphragm 29 is arranged in parallel in the valley on the back surface of the corrugated filter medium 23, and a protrusion 30 is raised on the rear end surface of the group of diaphragms on a circumference concentric with the rotary plate 21. The projection 30 is struck by a striking element 31 attached to the front surface of the rotary plate 27.

The rotational force of a power cord winding device (not shown) is transmitted to the rotating plate 27 via the large-diameter gear 28, which causes vibrations to be transmitted to the diaphragm 29 when winding or unwinding the cord. This allows the dust adhering to the corrugated filter medium 23 to fall into the dust chamber 32 below.

Therefore, the dust collector 33 is constituted by the above-mentioned primary filter 18, secondary filter 19, fixed plate 26, rotating disk 27, large-diameter gear 28, diaphragm 29, and the like.

By the way, in the upper part of the fixed frame 26, there is formed a grip part 34 which protrudes to the side opposite to the primary filter 18 (outside the dust collection box 17) and has a gripping recessed part on the lower surface.

This grip part 34 is formed in the downward direction of the dust collector 33, and is formed in the longitudinal direction of the proximal end of the top plate 34A, and has an upwardly directed protrusion in the center of the proximal end of the top plate 34A in the longitudinal direction. 35 is formed.

Notches 36 are formed on both the left and right sides of the protrusion 35, and when the top plate 34A is pressed downward by the elasticity of the top plate 34A and the elasticity of the portion held in the notches 36, the protrusion 35 is pushed downward. When it moves and the pressing force is released, it returns to its original position.

On the other hand, in the vicinity of the opening end of the dust collecting box 11 and at the center in the width direction of the top plate, an engagement hole 38 is formed into which the projection 35 is inserted and engaged.

Therefore, when the protrusion 35 engages with the engagement hole 38,
The grip portion 34 projects outward from the dust collection box 17.

Therefore, when attaching the dust collector 33 to the dust collection box 17, as shown in FIG. Grip the grip part 34 of the fixed frame 26 in the device 33, and press the top plate 3 of the grip part 34.
Press and hold the center part of 4A with your fingers to push down the protrusion 3, and in this state insert the dust collector into the dust collection box 17, and at the same time release the pressure and move the protrusion 35 into the engagement hole 38. It is sufficient to penetrate through the hole and engage and hold both 35 and 38.

When removing both parts 35 and 38, the grip part 34
The protrusion 35 can be pulled out downward from the engagement hole 38 by pressing and holding the dust collector 33, and the dust collector 33 can be pulled out rearward.

According to such a configuration, the elastic effect of the fixed plate top plate 34A can be greatly exhibited by the notch 36, and the vertical movement range of the protrusion 35 can be increased, so that the protrusion height can be increased, and the fixed state can be improved. can be made more certain.

The housing has a grip portion 34 on the upper part of the fixed frame 26, and the engagement hole 3
8, the engagement between the engagement hole 38 and the protrusion 35 can be released and the dust collector 33 removed from the dust collection box 17 at the same time, making it easy to use. gets better.

Furthermore, since the protrusion 35 is formed integrally with the fixed frame 26, various problems in terms of cost and quality can be solved compared to the case where the protrusion 35 is formed as a separate part, and the quality stability of the product is also improved.

Furthermore, since the grip part 34 is provided on the upper part of the fixed frame 26, the operation is much easier than the conventional gripping part in the vertical direction of the central part of the frame body and pulling out one by one. The movement feels natural and the operability is very good.

On the other hand, a suction hose 4 is provided at the front of the upper casing 12.
0 is connected to the connecting bent pipe 41. This connecting bent pipe 41 is rotatable around a vertical axis, and its base intake port 42 is connected to the lower casing 1 of the dust collection box 17.
When attached to the dust collecting box 1, the dust collecting box 17 is configured to face directly above inside the dust collecting box 17.

That is, the top plate 17A of the dust collection box 11 is formed with an insertion hole into which the proximal end 41A of the connecting curved pipe 41 can be inserted, and the outer surface of the proximal end of the connecting curved pipe 41 is formed on the periphery of the insertion hole. A gasket 43 is arranged to keep the airtight.

As is clear from the above explanation, according to the present invention, the protrusion that engages with the retaining part of the dust collection box is formed integrally with the grip part, and by forming notches on both sides of the protrusion, it can be used as a molding material. It is possible to effectively utilize the elasticity of the synthetic resin used in the dust collection, and to obtain an extremely simple and inexpensive structure for connecting and disengaging the dust collector and the dust collection box, and in addition, it is possible to apply force by holding the grip part. This allows the dust collection box and dust collection device to be engaged outward, and the dust collection device can be taken out by simply hooking your fingertips into the gripping recess in the grip and pulling it out, making it easy to attach and remove the device, making it easy to dispose of dust. A vacuum cleaner can be provided.

Furthermore, as mentioned above, the grip has a recess for gripping, so the dust collector can be held hanging from the fingertips, which further improves the operability of disposing of dust compared to conventional ones. be.
