Electric vacuum cleaning apparatus

Abstract

An electric vacuum cleaner apparatus includes: an electric vacuum cleaner; a primary dust container that separates and accumulates dust from dust-containing air to be sucked into the electric vacuum cleaner; a waste-outlet lid that opens and closes a waste outlet that discharges the dust from the primary dust container; a station that can store the electric vacuum cleaner; a secondary dust container including the station and fluidly connected to the primary dust container through the waste outlet when storing the electric vacuum in the station; a secondary electric blower that transfers dust from the primary dust container to the secondary dust container by applying negative pressure to the primary dust container through the secondary dust container; and a drive source that generates opening and closing drive force of the waste-outlet lid. The closing drive force is generated after the secondary electric blower stops generating the negative pressure for transferring the dust.

1 . An electric vacuum cleaning apparatus comprising:
 an electric vacuum cleaner;   a primary dust container that is provided with the electric vacuum cleaner, separates dust from dust-containing air to be sucked into the electric vacuum cleaner, and accumulates the dust;   a waste-outlet lid that opens and closes a waste outlet that discharges the dust from the primary dust container;   a station that can store the electric vacuum cleaner;   a secondary dust container that is provided with the station and is fluidly connected to the primary dust container through the waste outlet when the electric vacuum cleaner is stored in the station;   an electric blower that transfers the dust from the primary dust container to the secondary dust container by applying negative pressure to the primary dust container through the secondary dust container; and   a drive source that generates opening drive force and closing drive force of the waste-outlet lid,   wherein the drive source closes the waste-outlet lid by generating the closing drive force of the waste-outlet lid after the electric blower stops operation of generating the negative pressure for transferring the dust.   
     
     
         2 . The electric vacuum cleaning apparatus according to  claim 1 , wherein the drive source maintains a stopped state to close the waste-outlet lid after the electric vacuum cleaner is stored in the station and until a transfer of the dust from the primary dust container to the secondary dust container is started. 
     
     
         3 . The electric vacuum cleaning apparatus according to  claim 1 , wherein the electric blower generates the negative pressure after the drive source fully opens the waste-outlet lid. 
     
     
         4 . The electric vacuum cleaning apparatus according to  claim 1 , wherein the waste-outlet lid is an outward-opening type that opens toward outside of the primary dust container. 
     
     
         5 . The electric vacuum cleaning apparatus according to  claim 1 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.   
     
     
         6 . The electric vacuum cleaning apparatus according to  claim 1 , wherein the electric blower is provided in the station. 
     
     
         7 . The electric vacuum cleaning apparatus according to  claim 1 , further comprising an attaching detector configured to detect that the electric vacuum cleaner is attached to the station,
 wherein the electric vacuum cleaning apparatus permits transfer of the dust from the primary dust container to the secondary dust container when the attaching detector detects that the electric vacuum cleaner is attached to the station.   
     
     
         8 . The electric vacuum cleaning apparatus according to  claim 2 , wherein the electric blower generates the negative pressure after the drive source fully opens the waste-outlet lid. 
     
     
         9 . The electric vacuum cleaning apparatus according to  claim 2 , wherein the waste-outlet lid is an outward-opening type that opens toward outside of the primary dust container. 
     
     
         10 . The electric vacuum cleaning apparatus according to  claim 3 , wherein the waste-outlet lid is an outward-opening type that opens toward outside of the primary dust container. 
     
     
         11 . The electric vacuum cleaning apparatus according to  claim 8 ,
 wherein the waste-outlet lid is an outward-opening type that opens toward outside of the primary dust container.   
     
     
         12 . The electric vacuum cleaning apparatus according to  claim 2 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.   
     
     
         13 . The electric vacuum cleaning apparatus according to  claim 3 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.   
     
     
         14 . The electric vacuum cleaning apparatus according to  claim 4 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.   
     
     
         15 . The electric vacuum cleaning apparatus according to  claim 8 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.   
     
     
         16 . The electric vacuum cleaning apparatus according to  claim 9 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.   
     
     
         17 . The electric vacuum cleaning apparatus according to  claim 10 , further comprising a power transmission passage that transmits driving force from the drive source to the waste-outlet lid,
 wherein the drive source is provided in the station.
