Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention [Object of the Invention] (Industrial Application Field) The present invention relates to a vacuum cleaner equipped with a detachable dust collection filter. Regarding structure.

(Prior Art) Conventionally, in this type of vacuum cleaner, for example, a lid body having a suction port is removably provided on the front wall of the main body case, which faces the dust collection chamber and has an opening, and a dust collection filter is installed. A bag-shaped filter material is inserted through the opening, and the frame of the dust filter is airtightly clamped between the front wall and the lid, so that the dust filter is detachably attached. There is. Also, with a vacuum cleaner with this structure, when you open the lid to throw away the dust, it will come out from the opening of the dust collection filter! In order to prevent * from spilling, the front wall of the main case is tilted forward and downward.

However, such conventional vacuum cleaners have a structure in which the slanted front wall of the main body case protrudes beyond the frame of the dust collection filter, so it is difficult to remove only the lid from the main case. In recent years, cases have been unsharpened, and when the case is disposed of, dust tends to stick to and remain on the forwardly protruding portion of the lower part of the front wall, which is unsanitary.

Furthermore, as described above, the front wall of the main body case, in which the frame is tightly packed, protrudes beyond the frame of the dust collecting filter to the outer circumferential side, so that it takes time and effort to explain the dust collecting filter. Of course, a structure in which the frame of the dust collection filter is provided with a handle for attaching and detaching is also adopted, but if the handle is bent forward from the frame and is provided at the bottom, it will not be possible to collect the dust as described above. Leave the dust filter attached! ! ! It is placed at the top of the frame because it does not get in the way when disposing of dust. However, when the handle is provided on the top of the frame in this way, especially when removing the dust filter with the main body case horizontally, that is, with its bottom facing down, this dust collector In a vacuum cleaner, the front wall of the main body case protrudes further to the outer periphery than the frame of the particle collecting filter, which is in close contact with the front wall. It tends to stick to and remain on the protruding part of the front wall, and it takes time and effort to remove the dust filter, and since the handle is provided at the top of the frame, the opening of the dust filter cannot be easily removed. There was a problem that the dust was easily spilled because it was easy to face downwards.

The present invention aims to solve these problems.In particular, even when discarding dust without removing the dust collection filter, the dust does not adhere to the main body case, and the dust collection filter can be removed. It is an object of the present invention to provide a vacuum cleaner that can be easily operated and does not spill dust even when removed.

[Structure of the invention]

(Means for Solving the Problems) The vacuum cleaner of the present invention includes an electric blower inside the main body case, a dust collection chamber communicating with the electric blower located on the front side, and a dust collection chamber in the main body case. An opening is provided in the front wall facing the α chamber, and a lid body having a suction port facing the dust collection chamber is removably attached to the front side of the front wall, and a frame body having a handle and a lid body having a suction port facing the dust collection chamber are detachably attached to the front wall. A dust collection filter made of a provided filter material is attached and detached by clamping the frame between the front wall and the lid, and inserting the filter material into the dust collection chamber through the opening. On the front surface of the front wall, a sloped surface descending toward the front to which the frame of the dust collection filter is closely attached is formed, and a handle portion of the filter is protruded downward from the slope, and the front wall A cutout surface is formed below the inclined surface so as to face the front surface of the cutout surface with a space therebetween, and is positioned rearward from an imaginary plane extending the inclined surface downward.

(Function) In the vacuum cleaner of the present invention, in particular, when removing only the lid from the main body case but not removing the dust collecting filter, tilt the main body case and discard the dust accumulated inside the dust collecting filter. Dust is allowed to fall from the opening of the four filters, but at this time, the handle of the frame protrudes below the sloped surface of the front wall of the main case to which the frame of the dust collection filter is tightly attached. Dust falls without adhering to the front wall. In addition, when removing the dust filter, insert your finger into the space between the notch formed below the slope and the handle, pinch this handle, and as a natural movement, remove the dust filter from the frame. Tilt your body so that the opening faces upward and pull out the dust filter.

6 is formed in a box-shaped cross section, and locking claw portions 78 are bent inward on both side edges of this front side frame portion 76.
The locking claw portion 78 and the locking protrusion 77 are engaged with each other.
By engagement with the frame portions 75 and 76, both frame portions 75 and 76 are held in a joined state. Furthermore, a presser rib 79 is bent rearward at the lower edge of the inner circumference of the front frame portion 76 and is joined to the inner circumferential surface of the rear frame portion 75 from above. Note that the hinge portion 74 also serves as a handle portion.

Next, the operation of this embodiment will be explained.

Of course, when cleaning, a dust filter 71 is attached. To attach the filter 71, first insert the filter material 73 into the opening 56 of the main case 12.
Insert the frame body 72 into the dust collection chamber 51 in front of the main body case 12! ! 53 from the front side. Then,
The lid 13 is attached to the main body case 12 by sequentially engaging the engaging hole 68 of the lid 13 and the main body clamp 66 with the engaging protrusion 59 and the engaging groove 58 of the main case 12. In this state, the seal protrusion 57 of the main body case 12 is
1 frame body 72 from the rear! At the same time, the rear surface of the lid body 13 is closer to the frame body 72 than the front side! closely followed.

Of course, both frame portions 75 and 76 constituting the frame body 72 are also hermetically joined. Further, the hinge portion 14, which is a handle portion of the frame body 12, faces the notch surface 55 of the main body case 12 from the front with the space portion 81 interposed therebetween.

Note that commercially available tissue paper 80 as an auxiliary filter material can also be attached to the Shika filter 71 for use. When using tissue paper 80, use the fourth
As shown in the figure, both frame parts 75 and 76 are opened, a tissue paper 80 is placed, and while the tissue paper 80 is lightly pushed in by hand, both frame parts 75 and 76 are joined. By pinching the periphery of the tissue paper 80, this tissue paper 80
Attach the .

By the way, when the tissue paper 80 is attached, the presser rib 79 of the front frame section 76 located near the hinge section 74
and a corresponding portion of the rear frame portion 75 initially sandwich and hold the tissue paper 80. If there were no presser rib 79, the tissue paper 80 would be pushed inward too quickly when the tissue paper 80 is pressed in with a finger and the hinge portion 7 would not have any dimensional margin.
4, the tissue paper 80 is attached to both frame portions 7.
5.76 may not be reliably caught. However, as described above, in the vicinity of the hinge portion 74, the presser rib 79
Since the tissue paper 80 is first pressed down, the tissue paper 80 can be attached reliably. of course,
Even after the tissue paper 80 is attached, the provision of the presser rib 79 makes the attachment state of the tissue paper 80 more reliable.

Then, when removing, for example, the handle 16 is held and the suction port 63 is moved so as to face the mLM remover. When the electric blower 23 is driven, the itchy dust sucked in from the suction port 63 is stored in the dust collection filter 71 by the filter material 73, while the airflow that has passed through the filter material 13 is transferred to the urethane resin filter 52 and the communication port. 21 and is discharged from the ventilation port 29.

At this time, the valve body 65 opens as shown by the chain line in FIG. 1 due to wind pressure. By the way, when the tissue paper 80 is being used, the peripheral edge of the tissue paper 80 protrudes toward the outer periphery of the frame 72. However, a presser rib 79 is bent rearward at the lower part of the front frame portion 76 near which the operating portion of the valve body 65 is located, and the presser rib 79 is clamped to the inner peripheral surface of the rear frame 575. Been,
Valve body 6 out of the protruding part of tissue paper 80
The part near number 5 is folded back. therefore,
The valve body 65 opens and closes reliably without being obstructed by the protruding portion of the tissue paper 80.

Further, when tissue paper 80 is used, the tissue paper 80 is not entirely close to the filter material 73 at the time of installation. Due to the wind pressure and the accumulation of dust, the tissue paper 80 is removed from the filter material 73.
At this time, the tissue paper 80 slides inward between the frame parts 75 and 76. By the way, if the presser rib 79 is provided all the way around the front frame part 76, the tissue paper 80 will be attached to both frame parts 7.
5.76, the operation cannot be carried out smoothly, and there is a possibility that the tissue paper 80 may be torn in some cases. However, as described above, since the presser ribs 79 are provided only in necessary parts, both frame parts 7 of the tissue paper 80
Smooth sliding between 5° and 76° is not hindered.

When discarding the dust accumulated in the dust collecting filter 71, first, the main body clamp 66 is operated to remove the lid body 13. Normally, the dust filter 71 is further removed and the dust is thrown away, but the dust can also be thrown away with the fecal filter 71 attached. At this time, by tilting the main body case 12 so as to lift the rear side, dust is allowed to fall from the opening of the dust collection filter 71 formed by the frame 72. At this time, the frame 72 protrudes downward from the inclined surface 54 of the main body case 12, and the lower part of this inclined surface 54 is a cutout surface 55 that hangs down to the lower surface of the main case 12. Since the front lower part of the main body case 13 does not protrude forward from the frame 72, dust will not remain on the front lower part of the main body case 13.

When removing the dust collecting filter 71, insert your finger into the space 81 between the hinge part 74, which is the handle part, and the notch surface 55 of the main body case 12, pinch the hinge part 74, and remove the dust collecting filter 11. Pull it forward as shown in Figure 3.

In this manner, since the space 81 is provided between the hinge portion 74 and the main body case 12, the dust filter 71 can be easily removed. In addition, since the hinge part 74, which is a handle part, is located at the bottom of the dust filter 71, when removing the dust filter 71 with the main body case 12 horizontal as shown in FIG. The natural movement is to lift the frame 72 and bring it closer to the horizontal state while removing it. Therefore, the inclined surface 54 of the main body case 12 to which the frame 72 is closely attached
In addition to the fact that the dust collecting filter 71 is tilted forward and downward, the opening of the dust collecting filter 71 is never directed downward, so that the dust inside will not be accidentally spilled or spilled. Further, even when the deer collection filter 71 is removed in this manner, the presence of the cutout surface 55 at the lower front of the main body case 12 can reliably prevent dust from adhering to this portion.

Further, when reinstalling the dust filter 71, the operation becomes easy due to the presence of the cutout surface 55 that faces the hinge portion 74, which is a handle portion.

In addition, if you are using tissue paper 80,
After opening both frames 75 and 76 of the dust collecting filter 71, the dust is thrown away together with the Aishbaber 80.

Of course, the dust filter 11 can be attached and detached even when the main body case 12 is placed upright with its rear face down.

Further, as described above, the hinge portion 7 of the dust collecting filter 71
4 is also used as a handle for attaching and detaching, so the structure can be simplified.

〔Effect of the invention〕

According to the present invention, on the front surface of the front wall of the main body case, an inclined surface descending toward the front to which the frame of the dust collection filter is closely attached is formed, and an imaginary surface with the inclined surface extending downward is formed below the inclined surface. A cutout surface is formed rearward from the plane, and the handle of the frame protrudes from the slope and faces the cutout surface with a space in between, so that dust can be thrown away without removing the dust filter. At the same time, dust does not adhere to the lower part of the curved surface of the front wall, where dust tends to adhere in the past, and when removing the dust collection filter, it is easy to grasp the handle, so the dust collection filter can be easily attached and removed. Since the handle is located at the bottom of the dust filter, the opening will not face downward when the dust filter is removed, and dust will not spill out.
