Abstract

An electric vacuum cleaner apparatus includes: a station, an electric vacuum cleaner attachable to the station, and plural attaching detectors which can detect the electric vacuum cleaner is attached in the station. The electric vacuum cleaner includes a cleaner body; a tubular part connected to the cleaner body and sucks in dust; and a primary dust container that stores dust sucked in with the tubular part. The station includes a secondary dust container that stores dust discharged from the primary dust container. The electric vacuum cleaner apparatus permits transfer of dust from the primary dust container to the secondary dust container when at least two of the plural attaching detectors have detected the attaching of the electric vacuum cleaner to the station. The electric vacuum cleaner apparatus can reliably confirm the vacuum cleaner is placed at a correct position on the charging station so that dust to be discarded from the primary dust container to the secondary dust container does not leak around the electric vacuum cleaner apparatus.

Claims (33)

1. An electric vacuum cleaner apparatus, comprising:

a station;

an electric vacuum cleaner attachable to the station; and

a plurality of attaching detectors configured to detect that the electric vacuum cleaner is attached to the station,

wherein the electric vacuum cleaner comprises:

a cleaner body;

an air passage including a suction port, the air passage being connected to the cleaner body and configured to introduce dust sucked in from the suction port to the cleaner body; and

a primary dust container attached to the cleaner body, and configured to accumulate the dust introduced into the cleaner body,

wherein the station comprises:

a secondary dust container configured to accumulate the dust to be discharged from the primary dust container,

wherein the plurality of attaching detectors include a first attaching detector configured to detect that the air passage is in a state at a time of storage where the air passage is attached to the station, and

wherein the electric vacuum cleaner apparatus permits transfer of the dust from the primary dust container to the secondary dust container when at least two of the plurality of attaching detectors have detected an attaching of the electric vacuum cleaner to the station.

2. The electric vacuum cleaner apparatus according to claim 1 , wherein the plurality of attaching detectors include a second attaching detector configured to detect that the cleaner body is connected to the station.

3. The electric vacuum cleaner apparatus according to claim 2 ,

wherein the station includes an attachment to which the air passage can be attached, and

wherein the first attaching detector is configured to detect that the air passage is attached to the attachment.

4. The electric vacuum cleaner apparatus according to claim 3 , further comprising a handle that is provided on the cleaner body and can move between a use position and a storage position,

wherein the plurality of attaching detectors include a third attaching detector configured to detect that the handle is in the storage position.

5. The electric vacuum cleaner apparatus according to claim 2 , further comprising a handle that is provided on the cleaner body and can move between a use position and a storage position,

wherein the plurality of attaching detectors include a third attaching detector configured to detect that the handle is in the storage position.

6. The electric vacuum cleaner apparatus according to claim 1 ,

wherein the station includes an attachment to which the air passage can be attached, and

wherein the first attaching detector is configured to detect that the air passage is attached to the attachment.

7. The electric vacuum cleaner apparatus according to claim 6 , further comprising a handle that is provided on the cleaner body and can move between a use position and a storage position,

wherein the plurality of attaching detectors include a third attaching detector configured to detect that the handle is in the storage position.

8. The electric vacuum cleaner apparatus according to claim 1 , further comprising a handle that is provided on the cleaner body and can move between a use position and a storage position,

wherein the plurality of attaching detectors include a third attaching detector configured to detect that the handle is in the storage position.

9. The electric vacuum cleaner apparatus according to claim 1 , further comprising a notification device configured to perform notification when at least one of the attaching detectors does not detect the attaching of the electric vacuum cleaner to the station within a predetermined time after at least one of other attaching detectors detects the attaching of the electric vacuum cleaner to the station.

10. The electric vacuum cleaner apparatus according to claim 1 , wherein the electric vacuum cleaner apparatus starts transfer of the dust after a predetermined delay time elapses from permission to transfer the dust.

11. The electric vacuum cleaner apparatus according to claim 1 , wherein

the air passage further includes a collecting hose, and

the air passage is configured to introduce the dust sucked in form the suction port to the cleaner body through the collecting hose.

12. The electric vacuum cleaner apparatus according to claim 1 , wherein the electric vacuum cleaner apparatus permits the transfer of the dust when at least two including the first attaching detector out of the plurality of attaching detectors have detected the attaching of the electric vacuum cleaner to the station.
