  In the conventional vacuum cleaner described above, dust and dust collect in the dust collector, dust bag, auxiliary filter, exhaust filter and other dust collectors after a certain amount of use, so replace the dust collector with a new one. It is necessary to remove from the main body of the vacuum cleaner for cleaning or cleaning. In particular, self-propelled vacuum cleaners are often used in situations where there is no human monitoring. Check the dust collection state of the dust collector and replace the dust collector each time it is used.・ There is a tendency to clean, and the dust collector is frequently detached from the main body of the vacuum cleaner. At the time of detachment, in the vacuum cleaners as in Patent Documents 2 to 5, the dust collecting bag to which the dust is attached and the surface of the auxiliary filter and the exhaust filter on the dust collecting bag side are exposed. There arises a problem that a hand touches the part and the dust is scattered or dust is scattered in and around the main body.

  On the other hand, in an electric vacuum cleaner such as Patent Document 1, dust and dust collect on the dust collecting case and the filter surface facing the dust collecting case, and the dust collecting case is electrically connected with the filter holder and the filter attached. Since it is detached from the main body of the vacuum cleaner, the dust collection part of the dust collection case and the filter will not be exposed at the time of the separation, and your hands will touch the dust adhesion part to get dirty or dust will be scattered in and around the main body. There is nothing to do. However, in order to clean and replace the dust collecting case and the filter, it is necessary to further remove the filter holder from the dust collecting case and remove the filter from the filter holder after the dust collecting case is detached from the main body. Patent Document 1 does not disclose any method for removing the filter holder from the dust collecting case, how to remove the filter from the filter holder, and how to hold the filter by the filter holder. If the filter is difficult to remove or the filter is removed unexpectedly, the dust may come into contact with the dust collecting case or the dust adhering part of the filter, or dust may be scattered in or around the main unit. .

  The present invention solves the above-described problems, and the problem is that a vacuum cleaner capable of preventing a hand from being contaminated with dust and scattering of dust when the dust collector is detached, and The purpose is to provide a self-propelled vacuum cleaner.

  In the present invention, an electric blower that generates suction force, a dust collector that separates and collects dust and dust from external air, a suction port that sucks external air, a storage unit that stores the electric blower, and a dust collector In a vacuum cleaner provided with a main body provided with a mounting portion for detachably mounting the dust collector, an intake hole that communicates with the suction port and an exhaust hole that communicates with the storage portion when mounted on the mounting portion A dust box provided with a filter, a filter that allows air to pass through and does not allow dust and dust of a predetermined size or more, and a plurality of vent holes are provided on substantially the entire surface, and both side ends of the filter are inserted into both side ends.

On the other hand, when the handle 17d of the filter holder 17 is pinched from the mounted state of FIG. 5B and FIG. 6 and the filter holder 17 is pulled away from the dust box 15, the filter holder 17 holds the filter 16 while holding the filter 16. Leave 15e.

  When the dust box 15 is gripped and inserted into the mounting portion 2d of the main body 2 from the state shown in FIG. 5B, the bottom surface and the inclined surface of the dust box 15 are attached to the mounting portion 2d as shown in FIG. The dust box 15 is mounted on the mounting portion 2d in contact with the bottom surface and the partition wall 2e. In the mounted state, as described above, the dust box 15 and the mounting portion 2d have substantially the same size, so that the dust box 15 is held by the mounting portion 2d and does not play. The intake hole 15d of the dust box 15 communicates with the communication hole 2h and the suction port 2b of the main body 2, and the exhaust hole 15f of the dust box 15 communicates with the gap 2f, the vent hole 2g, and the storage portion 2c of the main body 2.

  As shown in FIG. 5A, with the dust collector 14 mounted on the mounting portion 2d of the main body 2, the cover 3 is closed and the operation unit 4 (FIG. 1) is operated to When cleaning is started, the vacuum cleaner 1 automatically travels while avoiding obstacles as described above, rotates each sub brush 9 (FIG. 3) and the main brush 10 (FIG. 3), and is an electric blower. At 11, a suction force is generated. Then, due to the suction force, external air is sucked in from the suction port 2b (FIG. 3) of the main body 2, and pushes the check valve 18 through the communication hole 2h of the main body 2 and the suction hole 15d of the dust box 15. Into the dust box 15. Then, dust and dust of a predetermined size are separated from the external air by the filter 16 in the vicinity of the exhaust hole 15f of the dust box 15, and the dust and dust are directed to the inside of the dust box 15 and the surface of the filter 16 facing the inside of the dust box 15. It is collected. Further, the air cleaned by the filter 16 passes through the exhaust hole 15f and the vent hole 17a of the filter holder 17 and flows out into the gap 2f of the partition wall 2e of the main body 2, and further the vent hole 2g of the partition wall 2e and the electric blower 11 The air is exhausted to the outside through the inside, the storage portion 2c, and between the main body 2 and the cover 3.

  When the vacuum cleaner 1 stops cleaning, if the cover 3 is opened, the upper case 15a of the dust box 15 is transparent, so that the state of dust and dust collected in the dust box 15 and the filter 16 is visually checked to some extent. I can confirm. If dust or dust accumulates in the dust box 15 or the like, it is urged to clean the dust collector 14.

  When the dust box 15 is gripped and pulled away from the main body 2 from the state shown in FIG. 5A, the dust box 15 is removed from the mounting portion 2d while the filter 16 and the filter holder 17 are mounted as shown in FIG. 5B. break away. In the detached state, the intake hole 15d of the dust box 15 is closed by the check valve 18, and the exhaust hole 15f is covered by the filter 16 and the filter holder 17, so that dust and dust collected in the dust box 15 are collected. Never go outside. Next, when the filter holder 17 is detached from the dust box 15 as described above, the dust box 15 can be cleaned such as disposal of dust and dust in the dust box 15 and cleaning of the dust box 15. Further, for example, in a garbage disposal site, the knob 16 d of the filter 16 is pinched and the filter 16 is slid upward with respect to the filter holder 17, or the dust of the filter 16 adheres from the vent hole 17 a of the filter holder 17. If it strikes the surface that is not, the filter 16 is detached from the filter holder 17 and can be discarded. Further, after the filter 16 is detached, the filter holder 17 can be cleaned and a new filter 16 can be attached to the filter holder 17.

  According to the above, dust and dust accumulate in the dust box 15 and the surface of the filter 16 facing the dust box 15, and the dust box 15 is detached from the mounting portion 2 d of the main body 2 of the vacuum cleaner 1 with the filter holder 17 and the filter 16 attached. Therefore, the dust adhering portions of the dust box 15 and the filter 16 can be prevented from being exposed at the time of the separation.

  Further, since the filter holder 17 is mounted on the mounting portion 15e of the dust box 15 by the attracting force of the magnets 19 and 20, the hole and the protrusion are engaged to mount the filter holder on the dust collecting case as described in Patent Document 1 described above. The filter holder 17 can be removed from the dust box 15 much more easily than the structure, and the hand does not touch the filter 16. In addition, since it is not necessary to provide engagement holes or protrusions in the dust box 15 and the filter holder 17, it is possible to keep the manufacturing costs of the dust box 15 and the filter holder 17 low.

  Further, since the filter 16 is held by inserting the both end portions of the fine dust layer 16a of the filter 16 into the grooves 17b at the both end portions of the filter holder 17, the filter allowance 16d at the upper end portion of the filter 16 is pinched. 16 is slid upward with respect to the filter holder 17, or the surface of the filter 16 that is not attached with dust from the vent hole 17 a of the filter holder 17 touches the dust-adhered portion of the filter 16. The filter 16 can be easily detached from the filter holder 17 without any trouble.

  Further, since the wall 17c is provided at the lower end portion of the filter holder 17, the filter 16 is unexpectedly detached from the filter holder 17 when the filter holder 17 and the filter 16 are handled after the filter holder 17 is detached from the dust box 15. Can be prevented.

  Therefore, in the self-propelled vacuum cleaner 1 that is often used in a situation where there is no monitoring by a person and the dust collector 14 is detached from the main body 2 for cleaning or replacement of the dust collector 14, When the dust box 15 is detached from the main body 2, when the filter holder 17 is detached from the dust box 15, and when the filter 16 is detached from the filter holder 17, the dust and the dust accumulated in the dust box 15 and the filter 16 are handled. It is possible to reliably prevent the dirt from being touched and the dust and dust from being scattered in and around the main body 2. In addition, since only one filter 16 is attached to the vacuum cleaner 1, it takes less time and time to replace the filter 16 than the conventional vacuum cleaners such as Patent Documents 1 to 5 described above. The purchase cost of the filter 16 and the manufacturing cost of the filter 16 by the manufacturer can be kept low.

  The present invention can adopt various forms other than the embodiment described above. For example, in the above embodiment, the example in which the knob allowance 16d is provided by extending the entire upper end of the fine dust layer 16a of the filter 16 outward is given, but the present invention is limited to this. For example, as shown in FIG. 11, a knob margin 16d ′ may be provided by extending a part of the upper end of the fine dust layer 16a of the filter 16 outward. That is, it is only necessary that the filter tab protrudes from the outer shape of the filter holder to the extent that it can be pinched while being held by the filter holder.

  Moreover, in the above embodiment, although the example which applied this invention to the self-propelled electric vacuum cleaner 1 is given, this invention is other than this, for example, the other running type which is pulled and run by people etc. The present invention can be applied to a general vacuum cleaner such as a vacuum cleaner or a canister type vacuum cleaner.
