Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a handy-type vacuum cleaner equipped with a detachable dust collection filter, and relates to the device structure of the dust collection filter.

(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 the dust collection filter is closed. A structure is adopted in which a bag-shaped filter material is inserted through the opening, and the frame of the dust collecting filter is airtightly clamped between the front wall and the lid, so that the dust collecting filter is detachably attached. There is. In addition, in vacuum cleaners with this structure, the front wall of the main body case is tilted forward and downward to prevent dust from spilling out from the opening of the dust collection filter when the lid is opened to throw away dust. A similar structure has also been adopted.

However, in vacuum cleaners with this conventional structure, the slanted front wall of the main body case protrudes beyond the frame of the dust collection filter, so it is especially difficult to remove only the lid from the main case. In hand-held vacuum cleaners that have a dust collection case attached to the main body case so that it is not possible to dispose of the dust that has accumulated inside it, dust adheres to the forward protruding part of the lower part of the front wall and remains. There was a problem that it was easy and unsanitary.

In addition, in the vacuum cleaner having the conventional structure described above, the front wall of the main body case, to which the frame is tightly attached, protrudes beyond the frame of the dust collection filter to the outer periphery, so it takes time and effort to remove the dust collection filter. In addition, 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, the dust collection filter The handle is placed at the top of the frame because it would get in the way when throwing away dust with the handle attached. However, with this structure in which the handle is provided at the top of the frame, it is difficult to remove the dust filter, especially when the main body case is placed horizontally, that is, with its bottom surface facing down.
When the handle was pulled, the opening of the dust filter tended to face downwards, which caused dust to easily spill out.

(Problems to be solved by the invention) In the above conventional structure of the handy type vacuum cleaner,
The front wall of the main body case protrudes beyond the frame of the dust collection filter, which is tightly attached to the front wall, making it possible to dispose of dust without removing the dust collection filter. In this case, dust 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, it is difficult to collect dust. There was a problem that the opening of the dust filter tended to face downwards, making it easy for dust to spill out.

The present invention aims to solve these problems.In particular, even when the dust is thrown away without removing the dust collection filter, the dust does not adhere to the main body case, and it is also possible to remove the dust collection filter. To provide a handy type vacuum cleaner that can easily perform the work even when the work is done and prevents dust from spilling.

(Means for Solving the Problems) The handy type vacuum cleaner of the present invention has a built-in electric blower and a dust collection chamber that communicates with the suction side of the electric blower on the front side of the interior, and a front side facing the dust collection chamber. A main body case having an opening in the wall, a lid body having a suction port facing the dust collection chamber and detachably attached to the front wall of the opening, and a lid body having a handle part and located in the front wall opening. Consisting of a frame that is removably fitted to the inner circumferential wall and has a dust disposal opening having approximately the same opening area as the opening, and a filter material that is provided on the frame and is inserted into and removed from the dust collection chamber through the opening. a removable dust collection filter, the front wall of the opening is lowered forward to form an inclined surface over which the frame overlaps and is covered, and a portion of the inclined surface below the opening; A recess is formed by cutting out the handle in the vertical direction, and a handle formed on substantially the same plane as the frame is disposed on the upper surface of the recess.

(Function) In the handy type vacuum cleaner of the present invention, in particular, when only the lid is removed from the main body case and the dust collection filter is left attached, the dust collected inside the dust collection filter can be disposed of by tilting the main body case. Dust can be dropped from the opening of the dust collection filter,
At this time, since the handle of the frame protrudes below the inclined surface of the front wall of the main case to which the frame of the dust collection filter is in close contact, dust does not adhere to the front wall of the main case. Dust falls. In addition, when removing the dust filter, insert your finger into the recess formed at the bottom of the sloping surface, pick up the handle, and as a natural movement move the frame of the dust filter so that the opening faces upward. You can pull out this dust collection filter while tilting it.

Further, the handle portion formed by the hinge portion 74 is disposed in a recess 81 formed by cutting out a part of the lower portion of the inclined surface 54 of the front wall 53 in close contact with the frame 72 in the vertical direction. .

Next, the operation of this embodiment will be explained.

When cleaning, a dust collection filter 71 is attached. To install this dust collection filter 71,
First, the filter material 73 is inserted into the dust collection chamber 51 through the opening 56 of the main case 12, and the frame 72 is brought into close contact with the inclined surface 54 of the front wall 53 of the main case 12 from the front side. Next, cover body 1
The lid body 13 is attached to the main body case 12 by sequentially engaging the engaging hole 68 of No. 3 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 5 of the main body case 12
7 is airtightly attached to the frame 72 of the dust collecting filter 71 from the rear side, and the rear surface of the lid 13 is airtightly attached to the frame 72 from the front side, and both frame portions 75, which constitute this frame 72, 76 is also airtightly joined.Furthermore, the hinge portion 74, which is a handle portion of the frame body 72, is opposed to the front recess 81 formed in the cutout surface 55 of the main body case 12.

In addition, an auxiliary filter 8 is attached to the dust collecting filter 71.
0. For example, commercially available tissue paper may be attached and used. When using the auxiliary filter 80, as shown in FIG.
Open the 6, place the auxiliary filter 80, and while pushing the auxiliary filter 80 lightly with your hand, insert the auxiliary filter 80 into both frames 7.
The auxiliary filter 80 is mounted by joining the frames 75 and 76 and sandwiching the peripheral edge of the auxiliary filter 80 between the frame parts 75 and 76.

When the auxiliary filter 80 is attached, the presser rib 79 of the front frame part 76 located near the hinge part 74 and the corresponding part of the rear frame part 75 first sandwich and hold the auxiliary filter 80. This presser rib 79 first presses down the auxiliary filter 80 in the vicinity of the hinge part 74, so when the auxiliary filter 80 is attached while being pushed in with your fingers, the auxiliary filter 80 may be pushed inward too much, especially if there is no dimensional margin. The auxiliary filter 80 is not pinched between the frame parts 75 and 76 in the vicinity of the hinge part 74 which cannot be removed, and the auxiliary filter 80 can be reliably mounted. Also, even after installation, the presser rib 7
9, the attachment state of the auxiliary filter 80 becomes more reliable.

When cleaning, for example, the user holds the handle 16 and moves the suction port 63 while facing the surface to be cleaned. By driving the electric blower 23, the suction port 63
The dust sucked in from the air is collected in the dust collection filter 71 by the filter material 73, while the airflow passing through the filter material 73 passes through the urethane resin filter 52 and the communication port 21 to the exhaust port 29.
more excreted.

At this time, the valve body 65 opens as shown by the chain line in FIG. 1 due to wind pressure. And auxiliary filter 8
When using 0, this auxiliary filter 8
The peripheral edge of the frame 72 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 adjacent to the operating portion of the valve body 65, and the presser rib 79 and the inner circumferential surface of the rear frame portion 75 are sandwiched between the presser rib 79 and the inner circumferential surface of the rear frame portion 75. The protruding portion of the auxiliary filter 80 that is close to the valve body 65 is folded back. Therefore, the valve body 65 opens and closes reliably without being hindered by the protruding portion of the auxiliary filter 80.

Further, when the auxiliary filter 80 is used, the auxiliary filter 80 is not entirely close to the filter material 73 at the beginning of installation. and,
Due to wind pressure and dust accumulation, the auxiliary filter 80
is brought into close contact with the filter material 73, but at this time, the auxiliary filter 80 slides inward between the frame portions 75 and 76. Further, the presser rib 79 is not provided on the front side frame portion 76 over the entire circumference, but the presser rib 79 is
Since the auxiliary filter 9 is provided only in necessary parts, the auxiliary filter 80 slides smoothly between the frame parts 75 and 76, and the auxiliary filter 80, such as tissue paper, is not torn.

When discarding the dust accumulated inside the dust collection filter 71, first operate the body clamp 66 and remove the lid body 1.
Remove 3. Normally, the dust collecting filter 71 is further removed and the dust is thrown away, but the dust can also be thrown away with the dust collecting filter 71 attached. At this time, by tilting the main body case 12 so as to lift its 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 body 72 protrudes below the inclined surface 54 of the main case 12, and below the inclined surface 54 is a cutout surface 5 that hangs down to the lower surface of the main case 12.
5, that is, the main case 12
Since the front lower part of the body case 13 does not protrude forward from the frame body 72, dust does not adhere to and remain on the front lower part of the main body case 13.

When removing the dust filter 71, insert your finger into the recess 81 between the hinge part 74, which is the handle part, and the cutout surface 55 of the main body case 12, pinch the hinge part 74, and remove the dust filter 71. Pull it forward as shown in Figure 3. In this way, since the recess 81 is provided between the hinge portion 74 and the main body case 12, the dust filter 71 can be easily removed. Furthermore, since the hinge portion 74, which is a handle portion, is located at the bottom of the dust collection filter 71, when removing the dust collection filter 71 with the main body case 12 horizontal as shown in FIG. A natural action is to remove the frame 72 while bringing it closer to the horizontal state by lifting it. Therefore, in addition to the fact that the sloped surface 54 of the main body case 12 to which the frame 72 is closely attached is sloped in the downward direction toward the front, the opening of the dust collection filter 71 will not face downward. , internal dust will not spill out accidentally. Furthermore, even when the dust filter 71 is removed in this manner, the presence of the cutout surface 55 at the lower front of the main body case 12 reliably prevents dust from adhering to this portion.

Also, when reinstalling the dust filter 71, the cutout surface 5 facing the hinge portion 74, which is the handle portion,
5 makes the work easier.

In addition, when the auxiliary filter 80 is used, both frames 75 and 76 of the dust collection filter 71 are opened, and then the dust is thrown away together with the auxiliary filter 80.

Further, the dust collection filter 71 can be attached and detached even when the main body case 12 is erected with its rear face down.

Moreover, as mentioned above, since the hinge part 74 of the dust collection filter 71 is also used as a handle part for attaching and detaching,
The structure can be simplified.

(Effects of the Invention) According to the present invention, on the front surface of the front wall of the main body case,
The frame body of the dust collection filter overlaps to form an inclined surface that descends toward the front, and a part of the lower part of the opening of this inclined surface is cut out in the vertical direction to form a recess. Since the handle of the frame is located at the top of the frame, especially when disposing of dust without removing the dust collection filter, dust does not stick to the lower part of the front of the front wall, where dust tends to stick in the past. When removing the filter, it is easy to pick up the handle, so the dust collection filter can be easily attached and detached, and furthermore,
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.
