Here, the garbage container 51 can be a dust case, a garbage pack, or the like. A dust case is a box made of resin or the like. A garbage pack is a bag made of paper or the like having breathability as shown in FIG.

The container accommodating portion 52 is a space large enough to accommodate the garbage container 51. The container accommodating portion 52 is arranged inside the main body casing 11 so as to be adjacent to the suction device 12, and is interposed between the suction device 12 and the end portion of the air passage portion 13a of the suction air passage 13. A suction port 52a (FIG. 6) connected to the suction side of the suction device 12 is provided on one side of the container accommodating portion 52, and the air passage portion 13a of the suction air passage 13 is provided on the other side of the container accommodating portion 52. A connection port 52b (FIG. 5) is provided for the end portion of the. The connection port 52b has, for example, a round cross section so as to match the shape of the entrance portion of the dust pack. Further, it is preferable to install the air passage portion 13a at substantially the same height as the inlet portion of the dust pack (a height substantially in the middle of the main body casing 11).

The lid portion 53 is provided on the upper surface 11b or the like of the main body casing 11. The lid portion 53 is attached, for example, to an opening portion provided on the upper surface 11b of the main body casing 11 so as to open in the vertical direction with the hinge portion or the like as the center and toward the suction device 12. A lock portion having a claw portion and a claw hook portion is provided between the lid portion 53 and the opening portion of the main body casing 11 on the side opposite to the hinge portion. However, the configuration of the lid portion 53, the opening / closing direction, and the like are not limited to the above.

It may be a stepped surface having a depth equal to or equal to that of a stepped surface. By providing the seal portion 56 at a position deeper than the upper surface 11b of the main body casing 11 in this way, the rigidity of the lid portion 53 can be increased and the airtightness of the seal portion 56 can be improved.

<Action> The action of this example will be described below.

The flooring floor is cleaned with the flooring wiper 2. The flooring wiper 2 can wipe the floor surface 1 with the cleaning sheet 4 attached to the wiper head 2b by moving the wiper head 2b along the floor surface 1 while holding the handle 2a, and the cleaning sheet 4 can be used. Dust on the floor surface 1 can be attached and collected.

After cleaning the floor, dust is concentrated on the cleaning sheet 4 such as the side edge portion 2b1 of the wiper head 2b, and dust that does not adhere to the cleaning sheet 4 is also collected on the wiper head 2b. It is collected around the side edge portion 2b1 of. Floor cleaning is completed by discarding the dust adhering to the side edge portion 2b1 of the cleaning sheet 4 and the dust collected around the side edge portion 2b1 of the wiper head 2b. The cleaning sheet 4 can be replaced as appropriate when it becomes dirty to some extent, but it is possible to extend the replacement period by removing the adhering dust.

At this time, since more dust adheres to the side edge portion 2b1 of the wiper head 2b than to the floor wiping surface of the wiper head 2b, the dust adheres intensively to the side edge portion 2b1 of the wiper head 2b after cleaning the floor. The dust is manually removed and thrown away, which is cumbersome.

Therefore, in this embodiment, an electric dustpan 3 suitable for use in combination with the flooring wiper 2 is provided so that the work of removing and discarding the dust adhering to the flooring wiper 2 can be easily and surely performed.

<Effect> According to the electric dustpan 3 of this embodiment, the following effects can be obtained.

(Effect 1) The electric dustpan 3 is basically used by placing it on the floor surface 1, and dust collected by a floor cleaning tool such as a flooring wiper 2 is directly sent to the suction port 14 along the floor surface 1. By operating the suction device 12 in close proximity, dust can be sucked into the main body casing 11 at once from the suction port 14.

At this time, the suction port 14 of the electric dustpan 3 is formed into a slit shape into which the side edge portion 2b1 of the wiper head 2b of the flooring wiper 2 can be inserted. Therefore, since the suction port 14 has a shape suitable for inserting the side edge portion 2b1 of the wiper head 2b, dust adhering to the side edge portion 2b1 of the wiper head 2b and the side edge portion 2b1 of the wiper head 2b It is possible to efficiently and surely suck in the surrounding dust and remove it automatically.

Therefore, after cleaning the floor with the flooring wiper 2, it is possible to dispose of the dust cleanly without leaving behind, and after cleaning the floor, the dust concentrated on the side edge portion 2b1 of the wiper head 2b is collected on the side edge of the wiper head 2b. It is possible to eliminate the trouble of manually removing the portion 2b1 from the portion 2b1. Further, since the dust adhering to the cleaning sheet 4 attached to the wiper head 2b can be efficiently removed, the cleaning sheet 4 can be used for a long time, which is economical. Further, by using the electric dustpan 3, the cleaning sheet 4 can be kept in a clean state to which dust does not adhere, so that the effect of floor cleaning by the flooring wiper 2 can be enhanced.

Further, by making the suction port 14 a shape suitable for inserting the side edge portion 2b1 of the wiper head 2b, the use is limited so that the electric dustpan 3 cannot be used except for the wiper head 2b of the flooring wiper 2. It is also possible to eliminate malfunctions.

(Effect 2) The operation switch 21 may be provided inside the suction port 14. As a result, when the side edge portion 2b1 of the wiper head 2b is inserted into the suction port 14, the operation switch 21 is turned on by the side edge portion 2b1 of the wiper head 2b, so that the suction device 12 can be automatically operated. .. Therefore, it is possible to eliminate the trouble of performing a special switch operation for operating the suction device 12, and it is possible to improve convenience. Further, since the operation switch 21 is installed at a position inside the suction port 14 so as not to be operated carelessly, it is effective in preventing malfunction.

At this time, by installing the operation switch 21 at a position (particularly on the lower side) arranged vertically with respect to the intake port 22 from the suction port 14 to the suction air passage 13, the operation switch 21 and the intake port 22 are arranged. Since the distance between the two is shortened, dust and the like caught on the operation switch 21 can be strongly and reliably sucked and removed to the intake port 22. Further, by setting the operation switch 21 to be, for example, a lever switch suspended and supported so as to extend downward from the periphery of the intake port 22, the operation switch 21 (lever switch) itself is not caught by dust. Alternatively, it can be made so that dust is less likely to be caught.

(Effect 3) The gradual contraction shape portion 31 may be provided inside the suction port 14. As a result, the degree of vacuum inside the suction port 14 becomes higher toward the intake port 22 from the suction port 14 to the suction air passage 13, so that the dust that has entered the inside of the suction port 14 is sucked. It becomes possible to strongly suck the air from the air passage 13 into the main body casing 11.

(Effect 4) A scraping portion 41 may be provided on the side portion of the suction port 14. As a result, by rubbing the side edge portion 2b1 of the wiper head 2b against the scraping portion 41, the dust adhering to the side edge portion 2b1 of the wiper head 2b can be physically scraped by the scraping portion 41. Therefore, for example, even if the dust that has been concentrated on the side edge portion 2b1 of the wiper head 2b is not completely sucked and remains in the first suction, the scraping portion 41 can be used. Since it is possible to forcibly scrape off the dust adhering from the side edge portion 2b1 of the wiper head 2b without getting the hands dirty, it becomes easy to finally suck the dust into the suction port 14 and remove it.

(Effect 5) A container accommodating portion 52 may be provided in the middle of the suction air passage 13 so that the garbage container 51 can be detachably accommodated in the container accommodating portion 52. As a result, the dust sucked from the suction air passage 13 into the main body casing 11 is stored in the dust container 51, and when the dust container 51 is full of dust, the lid 53 of the main body casing 11 is opened to accommodate the container. The garbage container 51 can be taken out from the 52 and the garbage can be thrown away.

Then, a seal portion 56 having a seal member 54 and a seal surface 55 to be crimped by the seal member 54 when the lid portion 53 is closed is provided between the lid portion 53 and the container accommodating portion 52. The seal portion 56 can increase the degree of sealing of the container accommodating portion 52 to prevent a decrease in suction force.
