Abstract
Description
- The present invention relates to an electric vacuum cleaner having a dust collector chamber and an electric blower chamber which are juxtaposed with each other.
- In a conventional electric vacuum cleaner, as shown, e.g., in Japanese Patent Unexamined Publication No. 58-50923, an air-tight sealing between the dust collector chamber and the electric blower chamber is attained by abutting engagement between ribs of a body casing and a top casing. Further, concave-convex portions may be formed partially on abutment surfaces of the ribs so that an air-tightness is reinforced. Alternatively, a seal packing (such as a seal packing of moltprene) may be provided partially on the abutment surfaces of the ribs.
- Also, in a conventional electric vacuum cleaner, as shown, e.g., in Japanese Patent Unexamined Publication No. 61-209626, an accessory (nozzle) receptacle is formed rearward of the electric blower chamber, and a cover is mounted above the receptacle to open or close it.
- In the construction shown in Japanese Patent Unexamined Publication No. 58-50923, when the body casing and/or the top casing deforms, a gap occurs between the abutment surfaces of the ribs, thereby making it impossible to attain a sufficient air-tight sealing between the dust collector chamber and the electric blower chamber. Further, in case that the concave-convex portions are provided on distal ends of the ribs, the die must be formed with higher precision, thereby increasing in the mold expenses. In addition, in this case, the assembly of the component parts has to be performed very carefully, thereby necessitating an additional period of time for the assembly work.
- With the construction shown in Japanese Patent Unexamined Publication No. 61-209626, since the accessory receptacle is disposed in an exhaust air flow, a problem of how to prevent exhaust air from detouring arises. Another problem is that the mold is inevitably complicated. In addition, an opening/closing cover for covering the accessory receptacle has to be provided separately from the dust chamber cover.
- A first object of the present invention is, in view of the problems of the prior arts, to provide an electric vacuum cleaner which is capable of attaining, with a simple structure, a secure air-tight sealing between the dust collector chamber and the electric blower chamber.
- A second object of the present invention is, in addition to the first object, to provide an electric vacuum cleaner capable of achieving an intensive arrangement of component parts, and then suppressing an increase in the number of component parts required for an air-tight sealing.
- The first object is achieved by an arrangement where a duct communicating a dust collector chamber for collecting dust with an electric blower chamber accommodating an electric blower is formed integrally with the structural body of the cleaner.
- The second object is achieved by an arrangement where between a dust collector chamber having an opening on an upper portion thereof and an electric blower chamber, a duct communicating the dust collector chamber with the electric blower chamber and an accessory storage chamber are formed, and a dust chamber cover for covering the opening of the dust collector chamber extends over the duct and the accessory storage chamber.
- Since the duct communicating the dust collector chamber with the electric blower chamber is formed integrally with the structural body of the cleaner, the communication between the dust collector chamber and the electric blower chamber is established without increasing the number of component parts and without involving the air flow leakage.
- Since the dust chamber cover for covering the upper portion opening of the dust collector chamber also serves as a cover for lying over the accessory storage chamber, there is no need to prepare a cover for covering the accessory storage chamber as a member separate from the dust chamber cover for covering the upper portion opening of the dust collector chamber. Thus, component parts can be intensively arranged, the number of processes of assembly work can be reduced, and the mold expenses can be reduced.

Thedust collection bag 8 is supported by arib 29 formed on thelower casing 2 and a hingedmount 30. Thedust chamber cover 3 is provided with adust indicator 31 held in place by theinner cover 28 for indicating a time for the user to dispose of the collected dust. - A
dust collector chamber 32 having an opening on an upper portion thereof and anelectric blower chamber 48 having an opening on an upper portion thereof are juxtaposed in the lower casing. Aduct 33 is provided between thedust collector chamber 32 and theelectric blower chamber 48, which communicates thedust collector chamber 32 with theelectric blower chamber 48. Theduct 33 is formed integrally with thelower casing 2 when it is formed. - A
guard rib 34 and aprotection filter 35 are disposed on the side of theduct 33 which is closer to thedust collector chamber 32. - The
electric blower 6 is accommodated in theelectric blower chamber 48 while being fixed in the forward and rearward position byrubber members electric blower cover 40. Therubber member 36 is disposed in close contact with a sealingwall 38 of the electric blower chamber. Theduct 33 has an entrance opening connected to thedust collector chamber 32, an area of which is smaller than that of an exit opening connected to thesealing wall 38, thereby reducing the noise generated by theelectric blower 6 from being transmitted through theduct 33 to thedust collector chamber 32.

Thefurniture guard 5 is configured to surround thedust collector chamber 32 within thelower casing 2, and is mounted on thelower casing 2. - A
chamber 51 is provided between thedust collector chamber 32 and theelectric blower chamber 48 for storing accessories together with theduct 33. Therack 13 of thetop casing 4 is disposed to depend into thechamber 51. When the upper portion opening of thedust collector chamber 32 is closed by thedust chamber cover 3, thecover 3 extends over therack 13 of thetop casing 4. - Under the condition where the upper portion opening of the
dust collector chamber 32 is closed by thedust chamber cover 3, a wall 3a formed on thedust chamber cover 3 cooperates with aseal packing 49 provided on the edge of the upper portion opening of thedust collector chamber 32 to maintain an air-tightness between thedust collector chamber 32 and therack 13. Theseal packing 49 is integral with a furniture guard 5c. - As shown in Figs. 4 and 5, a cross-sectional configuration of the
duct 33 is such that a lower part thereof is curved, while the remaining part, i.e., upper and side parts are flat. Theduct 33 has a length a dimension with which a movable die for forming theduct 33 can be moved into and out from theelectric blower chamber 48. As shown in Fig. 1, a lower surface of theduct 33 is positioned higher than a bottom surface of thelower casing 2. As a result, a convex portion 1a is formed in thelower casing 2. - An air exhaust port 40a is formed in a portion of the
