Description
Technical Field
The present invention relates to a self-propelled cleaner.
Background
As an autonomous vacuum cleaner for cleaning dust on a floor or the like, patent document 1 proposes an autonomous vacuum cleaner including: a box body capable of automatically walking, which is provided with a suction inlet on the lower surface; a main brush provided to be rotatable at the suction port; and a side brush provided to be rotatable in front of the main brush on the lower surface of the case.
In this self-propelled cleaner, a rechargeable battery is built in the housing, and a drive/stop switch is provided on the upper surface of the housing. In addition, a dust collecting unit is detachably provided at the rear part of the case.
The dust collection unit has: a dust collection housing having a partition wall dividing the inlet port, the exhaust port, the inlet port side and the exhaust port side into two spaces, and a vent formed in a part of the partition wall; a filter provided in the vent; and an electric blower disposed in the space on the exhaust port side of the dust collection housing.
Further, a pair of positive and negative terminals electrically connected to the rechargeable battery via a lead wire is provided at the rear portion of the case, while a pair of metal terminals electrically connected to the electric blower via a lead wire is provided at the dust collection case of the dust collection unit. In a state where the dust collection unit is mounted at the rear of the case, these positive and negative terminals are electrically connected to a pair of metal terminals.
When the self-propelled cleaner is driven, dust on the floor flows into the space on the inlet side of the dust collection housing from the suction port and is collected, and air from which dust has been removed by the filter is discharged to the outside from the exhaust port through the electric blower.
When dust accumulated in the dust collecting space of the dust collecting unit is discarded, the dust collecting unit is taken down from the box body, and the dust in the dust collecting unit is discharged into the garbage can by directing the inflow port downwards. In this case, the dust collecting space can be cleaned using a brush as an accessory.

Disclosure of Invention
Problems to be solved by the invention
However, in the self-propelled cleaner of patent document 1, since the electric blower and the pair of metal terminals are provided in the dust collection unit, the dust collection housing cannot be washed with water. Therefore, fine dust adhering to the dust collection housing cannot be completely removed by the brush, and the dust collection housing cannot be cleaned sufficiently. In addition, since dust is likely to adhere to the pair of metal terminals, there is a concern that the metal terminals may have a poor contact with the positive and negative terminals on the case side.
In the self-propelled cleaner disclosed in patent document 1, when the dust collection housing is removed from the housing on the floor, the dust in the dust collection housing is likely to fall down from the inlet port onto the floor, and therefore the floor after cleaning may be soiled.
The present invention has been made in view of such circumstances, and an object thereof is to provide a self-propelled cleaner including a dust collecting unit that can be washed with water and is less likely to cause electrical failure.
Means for solving the problems
Therefore, according to the present invention, there is provided an autonomous vacuum cleaner including: a self-walking box body, which is provided with a suction inlet arranged on the lower surface and an exhaust outlet arranged at the rear part; and a dust collecting part arranged between the suction port and the exhaust port with a ventilation path therebetween,
the dust collecting part has a dust collecting box arranged at the suction inlet side and an electric blower arranged at the exhaust outlet side, and the dust collecting box and the electric blower are separated.
Effects of the invention
In the self-propelled cleaner of the present invention, the dust box of the dust collection unit and the electric blower are configured to be separable. Therefore, even after the dust box is removed from the box body and the dust in the dust box is discarded, the dust box can be washed with water to remove the fine dust without leaving any residue. That is, the dust box can be sufficiently cleaned.
Further, if the metal terminals on the dust collecting box side and the positive and negative terminals on the box side are connected and separated as in the conventional art, dust is likely to adhere to the terminals, and therefore, there is a fear that the metal terminals and the positive and negative terminals are in poor contact with each other.

In this case, by providing the inclined lower surface portion on the case side and the inclined upper surface portion on the dust collection box side, it is possible to avoid the defect that the 2 nd gasket is worn or dropped due to friction between other portions of the dust collection box and the 2 nd gasket.
(4) It can also be: the dust collecting box is provided with a dust falling prevention sheet at the inflow opening for preventing the dust in the dust collecting box from falling from the inflow opening.
Thus, when the dust box is taken off from the box body on the floor, the dust falling prevention sheet prevents the dust in the dust box from falling to the floor from the inflow port, thereby preventing the cleaned floor from being stained.
Furthermore, the disclosed embodiments are illustrative in all respects and should not be considered as limiting. The scope of the present invention is defined not by the above description but by the appended claims, and is intended to include all changes that come within the meaning and range of equivalency of the claims.
