Description

FIELD OF THE INVENTION

The invention relates to an electric vacuum cleaner containing a storage base and a vacuum cleaner body mounted on a storage base.

State of the art

A conventional electric vacuum cleaner comprises a housing having a first dust separation / collection unit and a loading base having a second dust separation / collection unit. A conventional electric vacuum cleaner uses a vacuum cleaner housing that is detachable from the base to collect dust from the floor. Then, when the vacuum cleaner body is mounted on the base, the first dust separation / collection unit communicates with the second dust separation / collection unit, and the conventional electric vacuum cleaner again collects dust collected in the first dust separation / collection unit of the vacuum cleaner body into the second base separation / dust collection unit (see, for example, JP No. 2008-79922).

Disclosure of invention

When the vacuum cleaner body is mounted on the loading base, with respect to the conventional vacuum cleaner, it is necessary to properly connect the loading base and the vacuum cleaner body by lifting the vacuum cleaner body and adjusting the relative spatial relationship of the loading base and the vacuum cleaner body. In addition, a conventional electric vacuum cleaner combines the lower surface of the vacuum cleaner body and the upper surface of the base for loading in order to form a mutual connecting surface and at the same time communicate the first dust separation / collection unit with the second dust separation / collection unit on the connecting surface.

As indicated above, a conventional electric vacuum cleaner has a structure for virtually simultaneously securing and disconnecting a connecting mechanism between the loading base and the vacuum cleaner body; and a communication mechanism between the first dust separation / collection unit and the second dust separation / collection unit. Thus, unfortunately, the load created by the internal force of the vacuum cleaner body prevents the reliable connections of the connecting mechanism and the communication mechanism and may prevent the reliable formation of a connecting channel between the first dust separation / collection unit and the second dust separation / collection unit. In addition, a conventional electric vacuum cleaner has a design for virtually simultaneously mounting and disconnecting a connecting mechanism between the loading base and the vacuum cleaner body; and a communication mechanism between the first dust separation / collection unit and the second dust separation / collection unit. Thus, unfortunately, improving the usability of the vacuum cleaner body reduces the ease of selecting the type of construction of the vacuum cleaner body.

The objective of the invention is to provide an easy-to-use electric vacuum cleaner that allows you to securely attach the storage unit to the vacuum cleaner body and disconnect this node from it and can maintain dust collection by the vacuum cleaner body for a long period of time.

This problem is solved in an electric vacuum cleaner according to the invention, comprising a storage base and a vacuum cleaner body mounted on a storage base; wherein the vacuum cleaner body comprises a base mounted on a storage base; a vertical hinged support node located on the base, a main part supported with the possibility of rotation of the vertical hinged support node; a first dust collecting unit located on a main body; an electric fan placed in the main part and in communication with the first dust collecting unit; the first connecting node in communication with the first dust collecting unit and closed with the possibility of opening and closing; the second connecting node in communication with the electric fan and closed with the possibility of opening and closing; and a switching valve that is located between the first dust collecting unit and the electric fan and closes the connecting hole between the first dust collecting unit and the electric fan when the second connecting unit is opened; wherein the storage base comprises a support assembly of a vacuum cleaner body; a second dust collecting unit located in the support block; a dust suction pipe formed in the first connection node with the possibility of mounting and disconnecting and communicated with the second dust collection unit; and an exhaust pipe in communication with the second dust collecting unit and formed in the second connection unit with a possibility of fastening and disconnecting, in this case, when the vacuum cleaner body is mounted on the support unit and the main part is properly moved up and down, the first connection unit is connected to the dust suction pipe and the second connection node is attached to the exhaust pipe.

Thus, the electric vacuum cleaner according to the invention has excellent controllability of the vacuum cleaner body, can securely attach the storage unit to the vacuum cleaner body and disconnect this node from it, and can maintain dust collection in the vacuum cleaner body for a long period of time.

The implementation of the invention

Next will be described an embodiment of an electric vacuum cleaner according to the invention with reference to figures 1-10.

Figure 1 shows an electric vacuum cleaner according to the invention in a storage state, a perspective view.

As shown in FIG. 1, an electric vacuum cleaner 1 according to the invention comprises a housing 2, a dust collecting hose 3, a hand-operated tube 4, a gripping part 5, an actuating unit 6, a retractable pipe 7, a suction nozzle 8 and a storage base 10.

The housing 2 of the vacuum cleaner has a connecting hole 2A. One end of the dust collecting hose 3 is connected to the connecting hole 2a with a possibility of fastening and disconnecting. The housing 2 of the vacuum cleaner is configured to be installed on the base 10 for storage.

The dust collecting hose 3 has a flexible, flexible, elongated and substantially cylindrical shape. One end of the dust collecting hose 3 is connected to the connecting hole 2a with a possibility of fixing and disconnecting. The dust collecting hose 3 is in communication with the interior of the vacuum cleaner body 2. The dust collecting hose 3 has a handle 11 (vertical gripper) located adjacent to the connecting hole 2a of the vacuum cleaner body 2.

One end of the handle-controlled tube 4 is mounted on the other end of the dust collecting hose 3. A hand-operated tube 4 communicates with the interior of the vacuum cleaner body 2 through a dust collecting hose 3.

The gripping part 5 is held by the user of the electric vacuum cleaner 1 to control the electric vacuum cleaner 1. The gripping part 5 is located on the other end of the hand-operated tube 4 and is formed so that it is bent to that end portion of the hand-controlled tube 4 where the dust collecting hose 3 is installed.

On the gripping part 5 is located the Executive unit 6. Using the Executive unit 6, the user of the electric vacuum cleaner 1 can set the electric vacuum cleaner 1 to many modes. The Executive unit 6 includes a switch 6A for stopping the operation of the vacuum cleaner 1 and a switch 6a for starting the operation of the electric vacuum cleaner 1.

Retractable pipe 7 has an elongated, elongated and essentially cylindrical shape. The retractable tube 7 has a telescopic structure made by expanding a plurality of cylindrical elements. One end of the retractable pipe 7 is attached to the other end of the hand-operated tube 4 with the possibility of attachment and detachment. The retractable pipe 7 communicates with the interior of the vacuum cleaner body 2 through a hand-operated pipe 4 and a dust collecting hose 3.

The suction nozzle 8 is connected to one end of the retractable pipe 7 with the possibility of mounting and disconnecting. The suction nozzle 8 is in communication with the interior of the vacuum cleaner body 2 through a pull-out pipe 7, a hand-operated pipe 4 and a dust collection hose 3. The suction nozzle 8 has a suction port (not shown). When the suction nozzle 8 is located on the floor F, the suction hole faces the floor F.

The storage base 10 has a support block 13 and a support post 14. The support block 13 has an inclined upper surface 13a (inclined mounting surface). The upper surface 13a of the support block 13 is intended for installation on it of the housing 2 of the vacuum cleaner. The support block 13 has a rotatable pedal 15. The support post 14 is located at an end portion on the lower side of the inclined support block 13. The support post 14 extends and is oriented essentially in a direction vertically upward when the storage base 10 is set essentially horizontal floor F. The upper end of the support post 14 is connected to the handle 11 of the hose 3 for collecting dust with the possibility of attachment and separation.

Figure 2 shows an electric vacuum cleaner according to the invention in a state of use, perspective view.

As shown in FIG. 2, when the vacuum cleaner body 2 is disconnected from the storage base 10 and placed on the floor F, the electric vacuum cleaner 1 becomes a vacuum cleaner 16 containing the housing 2, a dust collection hose 3, a hand-operated tube 4, a gripping part 5, executive unit 6, a retractable pipe 7 and a suction nozzle 8.

Figure 3 shows the housing of an electric vacuum cleaner according to the invention, front view.

Figure 4 shows the housing of an electric vacuum cleaner according to the invention, a top view.

Figure 5 shows the housing of an electric vacuum cleaner according to the invention, side view.

As shown in FIGS. 2-5, the housing 2 of the electric vacuum cleaner 1 comprises a base 17 mounted on the floor F; a vertical hinged support node 18 mounted on the base 17; and the main part 19, which can rotate around the rotary axis x (in the direction indicated by the solid arrow Rx in FIGS. 2 and 5) of the vertical hinged support unit 18.

When the vacuum cleaner body 2 is stored on the storage base 10, the base 17 is located on a support block 13 of the storage base 10. Meanwhile, when the body 2 of the vacuum cleaner is disconnected from the storage base 10 in order to use it for cleaning, the base 17 is mounted on the floor F. The base 17 comprises a body 21 located on the floor F; a rotatable base 22 mounted rotatably on the base body 21; and a battery 23 supplying power to the main part 19.

At least three rollers 24 (wheels) are attached to the lower surface of the base body 21. If the vacuum cleaner body 2 is mounted essentially on the horizontal floor F, the rollers 24 are arranged so that the orthographic projection of the center of gravity of the vacuum cleaner body 2 on the floor F is inside the polygon whose vertices are all the rollers 24, for example, inside a triangle for three rollers 24 and pentagon for five rollers. In particular, the rollers 24 are located essentially at equal distances near the outer circumference of the lower surface of the base body 21. Thus, the housing 2 of the vacuum cleaner can stably rotate and move along the floor F using the rollers 24.

The rotary base 22 can rotate around the rotary axis z (in the direction indicated by the solid arrow Rz in FIGS. 2 and 4) of the base body 21. If the vacuum cleaner body 2 is mounted on the floor F, the rotary axis z is located perpendicular to the floor F. In particular, if the vacuum cleaner body 2 is mounted on the floor F, for example, on a substantially horizontal floor, the rotary axis z is substantially vertical. On the rotary base 22 is a vertical hinged support node 18.

The battery 23 is placed in the base 17. In particular, the battery 23 is located around the main part 19. It should be noted that the battery 23 may be located so that it will surround the entire periphery of the main part 19, or may be located so that it will surround only the lateral periphery of the main part 19 near the vertical hinged support node 18. In addition, the battery 23 can be placed in any of the elements, which include the main part 21 of the base and the rotary base Chapter 22.

The vertical articulated support assembly 18 supports a main body 19 that can rotate about a pivot axis x. If the body 2 of the vacuum cleaner is mounted on the floor F, for example, essentially on a horizontal floor, the rotary axis x is essentially parallel to the floor F.

The main part 19 is supported by a vertical hinged support unit 18 and can be rotated from one position in which it is located in one direction relative to the floor F, on which the base 17 is mounted essentially parallel to this floor, to another position in which it is located in another the direction with respect to the floor F, on which the base 17 is mounted, substantially parallel to this floor; and can be rotated 360 ° around a normal floor line using a swivel base 22. The main part 19 comprises a dust separation / collection unit 26 and an electric fan 27. The main part 19 has a handle 28 and an outlet for the main part (not shown) through which air is diverted from the electric fan 27. In addition, the main part 19 has a connecting hole 2a to which a dust collection hose 3 is attached. It should be noted that one position of the main part 19, in which it is located in one direction relative to the floor, essentially parallel to this floor, is a position in which the connecting hole 2A is oriented in one essentially horizontal direction, and the other position of the main part 19, in which it is located in a different direction relative to the floor, substantially parallel to that floor, is a position in which the connecting hole 2a is oriented in a different, essentially horizontal direction.

If you pull the hose to move the body 2 of the vacuum cleaner, the main part 19 will respectively move up and down and rotate relative to the floor F, on which the base 17 is installed, thereby preventing the hose 3 from collecting dust. In particular, as shown in FIG. 5, the main body 19 moves up and down, respectively, following the direction in which the dust collecting hose 3 is pulled. For example, when the dust collecting hose 3 is pulled in one direction substantially horizontal with respect to the floor F, the main part 19 forces the connecting hole 2a to follow the substantially horizontal direction (solid arrow A in FIG. 5). Furthermore, when the dust collecting hose 3 is pulled in a direction substantially vertical with respect to the floor F, the main part 19 forces the connecting hole 2a to follow essentially in the upward direction (solid arrow B in FIG. 5). In addition, when the dust collecting hose 3 is pulled in another direction substantially horizontal with respect to the floor F, the main part 19 forces the connecting hole 2a to follow in another substantially horizontal direction (solid arrow C in FIG. 5). The main body 19 accordingly changes the direction of the connecting hole 2a, following the direction in which the dust collection hose 3 is pulled in a rotation range. Thus, the electric vacuum cleaner 1 can prevent the bending of the dust collecting hose 3 by following the dragging of the vacuum cleaner body 2, and can prevent the reduction of the suction efficiency due to the bending of the dust collecting hose 3.

The vacuum cleaner body 2 has a snap mechanism 30 (fastening / detaching mechanism). The snap mechanism 30 includes a locking protrusion 30a formed on a vertical articulated support assembly 18; and a locking recess formed in the main part 19. The locking mechanism 30 is configured so that the main part 19 can be temporarily secured at a predetermined angle using the locking protrusion 30a and the locking recess 30b, which can be mutually fixed and disconnected. When the locking protrusion 30a and the locking recess 30b are connected to each other, the locking mechanism 30 temporarily locks the rotatable main part 19 in the corresponding rotary position. In particular, when the vacuum cleaner body 2 is mounted on the floor F, for example, on a substantially horizontal floor, the latch mechanism 30 can be designed so that the connecting hole 2a temporarily fixes the main part 19 in an upwardly upright position.

When the vacuum cleaner 16 is used for cleaning, the vacuum cleaner body 2 is disconnected from the base 10 for storing the electric vacuum cleaner 1 and placed on the floor F. When the switch 6b of the actuator unit 6 is pressed, the vacuum cleaner 16 operates so that the electric fan 12 starts to work, and to the separation unit 26 / dust collection is a vacuum. The vacuum acts on the suction nozzle 8 through the connecting hole 2a, the dust collecting hose 3, the hand-operated tube 4 and the extension pipe 7. Next, the vacuum cleaner 16 draws in air with dust accumulated on the floor F through the suction hole of the suction nozzle 8 for cleaning the floor F. Dust-containing air drawn into the suction nozzle 8 is separated into air and dust by a dust separation / collection unit 26 placed in the vacuum cleaner body 2. Separated dust is collected in the dust separation / collection unit 26. Meanwhile, the separated air passes through the electric fan 27 and is discharged through the outlet of the main part to the outside.

Figure 6 shows the housing of an electric vacuum cleaner according to the invention, a sectional view.

As shown in Fig.6, the housing 2 of the electric vacuum cleaner 1 contains a base 17, a vertical hinged support node 18 and the main part 19.

The base 17 contains the main part 21 and the rotary base 22.

The roller 24 of the main part 21 of the base is mounted to rotate on the axis 32 of the roller located on the lower side of the main part 21 of the base. The pivot axis Rc of each roller axis 32 is substantially vertical with respect to the floor F on which the base is located and with which the roller 24 is in contact. All of the roller axes 32 are parallel to each other. The rotary axis Rc of the roller axis 32 does not intersect the axis 24a of the roller 24, and these axes are intersecting.

The main part 19 comprises a connecting pipe 33 having a connecting hole 2 a of the housing 2 of the vacuum cleaner; a dust separation / collection unit 26 (a first dust collection unit) in communication with the connecting pipe 33; and an electric fan 27 in communication with the dust separation / collection unit 26.

The open end of the connecting pipe 33 is the connecting hole 2A of the housing 2 of the vacuum cleaner. The Central axis "c" of the connecting pipe 33 is located in any of the directions along the surface (for example, in the section in Fig.6), normal to the rotary axis x. In particular, the connecting pipe 33 is located in a position where its central axis "c" is located along a surface perpendicular to the rotary axis x, while the connecting hole 2a is open in a direction remote from the rotary axis x, and the connecting pipe 33 is located at the farthest distance from the rotary axis x.

In addition, the main part 19 comprises a connecting pipe 35 for removing dust (first connecting element) and an inlet connecting pipe 36 (second connecting element) located on one side surface, for example the lower surface 19a, where the angle of decrease or angle of elevation changes when moving up and down.

The dust removal connecting pipe 35 communicates the interior of the dust separation / collection unit 26 with the outer side of the main body 19. The dust removal connecting pipe 35 has a valve 37 that can open and close. The valve 37 is forced to move in the closing direction of the connecting pipe 35 to remove dust.

The inlet connecting pipe 36 communicates the upstream side of the electric fan 27 with the outside of the main body 19. In addition, the inlet connecting pipe 36 has an air channel switching unit 38 interposed between the dust separating / collecting unit 26 and the electric fan 27. Node 38 the switching channel of the air channel has a switching valve 39. The switching valve 39 provides a message of the internal space of the node 26 separation / collection of dust with the upstream side The electrical fan 27 and is forced to move toward the blocking compound between said side of the electric blower 27 and the outside of the main body 19.

In addition, the main part 19 has handles 28a and 28b axisymmetrically located relative to the rotary axis x. The handle 28a of the main part is rotatably gripped by the main part 19, in which it is located in one direction relative to the floor F, on which the base 17 is located essentially parallel to this floor. On the other hand, the handle 28b of the main body is rotatably gripped by the main body 19 in which it is located in a different direction relative to the floor F, on which the base 17 is located substantially parallel to this floor. The housing 2 of the vacuum cleaner can be moved in any position of the main part 19, oriented in any rotational direction, using the handles 28a and 28b of the main part. The handles 28a and 28b of the main part increase the transportability of the vacuum cleaner body 2.

7 and 8 show a part of a switching unit of an air channel of an electric vacuum cleaner body according to the invention, a perspective view. Fig. 7 shows an air channel switching assembly from the side of the dust separation / collection unit. On Fig shows the node switching the air channel from the side of the electric fan.

As shown in FIGS. 7 and 8, the air channel switching unit 38 of the vacuum cleaner body 2 includes a plate 41 having a first hole 40 communicating the dust separation / collection unit 26 with an electric fan 27; a movable plate 42 mounted for movement on the plate 41; link 43, turning due to the movement of the plate 42; and a switching valve 39, rotated by rotation of the link 43.

The plate 41 has a wall 45 having a second hole 44, communicating located upstream side of the electric fan 27 with the outer side of the main part 19.

The switching valve 39 comprises a first body 39a for opening and closing the first hole 40 (connecting hole) and a second body 39b for opening and closing the second hole 44. The first valve body 39a and the second body 39b act so that when one valve body closes one hole , the other valve body opens another hole. In particular, the first valve body 39a and the second valve body 39b are operable such that when the first valve body 39a closes the first hole 40, the second valve body 39b opens the second hole 44. In contrast, the first valve body 39a and the second valve body 39b operate so that when the second valve body 39b closes the second hole 44, the first valve body 39a opens the first hole 40. The switching valve 39 opens the first hole 40 and is forced to move in the closing direction of the second hole ment 44 by an elastic member (not shown) such as a spring. The air channel switching unit 38 uses force due to the elastic member to communicate the dust separation / collection unit 26 with the electric fan 27 and block the message between the upstream side of the electric fan 27 and the outer side of the main part 19.

When the movable plate 42 moves inside the main part 19, the air channel switching unit 38 actuates the switching valve 39 through the link 43 to close the first hole 40 and open the second hole 44. With this operation, the air channel switching unit 38 blocks the connection between the separation unit 26 / dust collection and the electric fan 27 and communicates located upstream side of the electric fan 27 with the outer side of the main part 19 (double dash-dot line in Fig.7 and 8).

In Fig.9 shows an electric vacuum cleaner according to the invention, a view in partial section.

As shown in FIG. 9, the base 10 for storing an electric vacuum cleaner 1 comprises a dust collecting unit 47 (second dust collecting unit) having a larger volume than a dust separating / collecting unit 26 of the vacuum cleaner body 2; a dust suction pipe 48, one end portion of which is located in the support column 14, and the other end portion is in communication with the dust collecting unit 47; an exhaust pipe 49, one end portion of which is located in the support column 14, and the other end portion is in communication with the dust collecting unit 47; and a movable mechanism 51 located above the support block 13. In addition, the storage base 10 has a charger (not shown) for charging the battery 23 of the cleaner body 2.

The dust collecting unit 47 is placed in the support block 13.

The opening ends 48a and 49a adjacent to one end portion of the dust suction pipe 48 and the exhaust pipe 49 are located in the support column 14. The opening end 48a of the dust suction pipe 48 is formed in the connecting pipe 35 to remove dust from the vacuum cleaner body 2 with a possibility of fastening and disconnecting. In contrast, the opening end 49a of the exhaust pipe 49 is formed in the inlet connecting pipe 36 of the housing 2 of the vacuum cleaner with the possibility of mounting and disconnecting. The relative spatial position of the opening opening 48a of the dust suction pipe 48 and the opening end 49a of the exhaust pipe 49 is a configuration corresponding to the spatial relative position of the dust removal connecting pipe 35 and the intake connecting pipe 36.

The movable mechanism 51 has a protruding portion 5la formed to protrude from the upper surface 13a of the support block 13. The protruding portion

51a is formed with the possibility of fastening and disconnecting in the recess 17a located on the lower surface of the base 17 of the housing 2 of the vacuum cleaner. The movable mechanism 51 is designed so that it can move the protruding portion 51a up and down along the slope of the upper surface 13a of the support block 13.

When the vacuum cleaner body 2 is placed on the upper surface 13a of the support block 13, the charger electrically connects the storage base 10 and the vacuum cleaner body 2. Thus, the battery 23 is being charged. The charger can electrically connect the contact points (not shown) of the cleaner body 2 and the storage base 10, or can electrically connect them in a non-contact manner.

When the vacuum cleaner body 2 is transferred to the upper surface 13a of the support block 13 and the protruding portion 51a of the movable mechanism 51 is inserted into the recess 17a of the vacuum cleaner body 2, the movable mechanism 51 moves down onto the upper surface 13a of the support block 13 by the weight of the vacuum cleaner body 2 and guides the vacuum cleaner body 2 to the stand 14.

Then, the vacuum cleaner 1 moves the vacuum cleaner body 2 closer to the support column 14 and moves the main part 19 of the vacuum cleaner body 2 up, down, or to an appropriate storage position. The opening 48a of the dust suction pipe 48a is connected to the connecting pipe 35 to remove dust from the vacuum cleaner body 2, while the opening 49a of the exhaust pipe 49 is connected to the inlet connecting pipe 36 of the vacuum cleaner body 2. At this time, when the movable plate 42 is moved inside the main part 19 by means of the plate protrusion 14a located in the support column 14, the air channel switching unit 38 of the vacuum cleaner body 2 activates the switching valve 39.

The storage position of the vacuum cleaner body 2 may be a position in which the main part 19 can freely move up and down, and the user of the electric vacuum cleaner 1 grabs the handle 11 of the dust collecting hose 3, while the main part 19 is held at a predetermined angle by the latch mechanism 30 of the body 2 vacuum cleaner.

The vacuum cleaner 1 comprises a housing 2 located on the storage base 10, and sequentially reports a dust separation / collection unit 26 of the vacuum cleaner body 2, a dust collecting unit 47 of the storage base 10, and an electric fan 27 of the vacuum cleaner body 2.

10 shows a storage unit according to the invention, a perspective view in partial section.

As shown in FIG. 10, the storage base 10 comprises a pedal 15 rotatably mounted in the support block 13; and a movable drive mechanism 53 transmitting the drive energy of the pedal 15 to the movable mechanism 51. When the pedal 15 is pressed, the movable mechanism 51 gradually rises upward along the inclined upper surface 13a of the support block 13 using the movable drive mechanism 53. The vacuum cleaner body 2 moves upward along the inclined upper surface 13a of the support block 13.

The movable mechanism 51 comprises a rail 51b. The movable drive mechanism 53 comprises a plurality of gears 53a, 53b, 53c and 53d. The movable drive mechanism 53 sequentially transfers the drive energy applied to the pedal 15 to the gears 53a, 53b, 53c and 53d, and allows the movable mechanism 51 to be moved by means of a rack 51b meshed with the gear 53d.

The cleaning operation performed by the electric vacuum cleaner 1 according to the invention will be described below.

First of all, the user of the electric vacuum cleaner 1 disconnects the housing 2 of the vacuum cleaner from the base 10 for storage. At this time, the user of the electric vacuum cleaner 1 grabs the handle 11 of the dust collecting hose 3 and releases the stopper between the handle 11 and the support column 14. At the same time, the user depresses the pedal 15 of the storage base 10 to disconnect the vacuum cleaner body 2 located on the support block 13 , from the support post 14. Then, the user of the electric vacuum cleaner 1 can easily separate the cleaner body 2 from the upper surface 13a of the support block 13.

Further, the user of the electric vacuum cleaner 1 installs the body 2 of the vacuum cleaner, separated from the base 10 for storage, on the floor F, for example on the floor surface.

Then, the user of the electric vacuum cleaner 1 places the suction nozzle 8 on the floor F and presses the switch 6b while holding the gripping part 5. Next, the fan 27 starts working according to the operation mode set on the switch 6b.

Then, the user of the electric vacuum cleaner 1 moves the hand-operated tube 4 and the extension tube 7 while holding the gripping part 5 to move the suction nozzle 8.

At this time, for example, when the user of the electric vacuum cleaner repeatedly moves the gripping part 5 back and forth to clean the floor F, the hand-operated tube 4, the extension tube 7 and the suction nozzle 8 reciprocate back and forth. With this movement, the main part 19 of the body 2 of the vacuum cleaner moves up and down relative to the rotary axis x of the vertical hinged support unit 18, following the bending of the dust collecting hose 3. This also applies when the user of the electric vacuum cleaner 1 repeatedly moves the gripping part 5 up and down to clean the wall.

When the user of the electric vacuum cleaner 1 suddenly changes the forward direction of the gripping part 5, the vacuum cleaner body 2 is rotated around the rotary axis z, following the bending of the dust collecting hose 3, by means of the rotary base 22 or the rollers 24.

When the user of the electric vacuum cleaner 1 moves the gripping part 5 from the place that has been cleaned, the vacuum cleaner body 2 moves up or down and rotates, following the bending of the dust collecting hose 3, with the help of a vertical hinged support unit 18, a rotary base 22 and rollers 24 for floor movements F.

Dust from floor F is drawn together with air into the suction inlet of the suction nozzle 8. The dust-containing air drawn into the suction nozzle 8 passes through the extension pipe 7, the hand-operated pipe 4, the dust collecting hose 3 in this order and passes through the connecting hole 2a the housing 2 of the vacuum cleaner and is drawn into the housing 2 of the vacuum cleaner.

The dust-containing air drawn into the inside of the vacuum cleaner body 2 is sent to the dust separation / collection unit 26. Here, dust-containing air is separated into air and dust by the dust separation / collection unit 26. The separated dust is collected using the dust separation / collection unit 26. Meanwhile, the separated air is drawn in by the electric fan 27, passes through the electric fan 27, cooling the electric fan 27, and then leaves the outlet of the main part to the outside of the vacuum cleaner body 2.

Upon completion of cleaning, the user of the electric vacuum cleaner 1 presses the switch 6a. As a result, the electric fan stops.

Next, the user of the electric vacuum cleaner 1 transfers the vacuum cleaner 16 to the base 10 for storage and lifts the body 2 of the vacuum cleaner, capturing the handle 11 located on the dust collecting hose 3.

At this time, the main part 19 is oriented upward, and the vacuum cleaner body 2 is oriented upward through the connecting hole 2a by means of a dust collection hose 3 connected thereto.

Then, the user of the electric vacuum cleaner 1 lifts the vacuum cleaner body 2 above the support unit 13 and sets the recess 17a of the vacuum cleaner body 2 on the protruding portion 51a of the storage base 10.

The vacuum cleaner body 2 moves the movable mechanism 51 and lowers onto the upper surface 13a of the support block until the vacuum cleaner body 2 comes close to the support column 14.

Then, the user of the electric vacuum cleaner 1 grabs the handle 11 to move up or down or rotate the main part 19 in order to set the body 2 of the vacuum cleaner in an appropriate storage position. Then, the opening 48a of the dust suction pipe 48a is connected to the connecting pipe 35 to remove dust from the cleaner body 2. Meanwhile, the opening opening 49a of the exhaust pipe 49 is connected to the inlet connecting pipe 36 of the cleaner body 2. At this time, the movable plate 42 of the vacuum cleaner body 2 moves to the plate protrusion 14a located in the support column 14 to actuate the switching valve 39.

Thus, the electric vacuum cleaner 1 comprises a vacuum cleaner body 2 located on the storage base 10, and sequentially communicates a dust separation / collection unit 26 of the vacuum cleaner body 2, a dust collecting unit 47 of the storage base 10 and an electric fan 27 of the electric vacuum cleaner body.

An electric vacuum cleaner 1 drives an electric fan 27 for a desired time. Accordingly, the dust accumulated in the dust separation / collection unit 26, together with the air, passes through the dust suction pipe 48 and is directed to the dust collection unit 47. The dust-containing air directed to the dust collecting unit 47 is separated into air and dust in the dust collecting unit 47. Separated dust is collected in the dust collecting unit 47. Meanwhile, the separated air passes through the exhaust pipe 49 and is drawn into the electric fan 27, passes through the electric fan 27 and leaves the outlet of the main part to the outside of the vacuum cleaner body.

According to the design of the electric vacuum cleaner 1, when the vacuum cleaner body 2 is placed on the storage base 10, first of all, the mass of the vacuum cleaner body 2 acts on the storage base 10 and subsequently the dust separation / collection unit 26 and the dust collection unit 47 of the main part 19 can be communicated with each other another due to a sufficiently small effort compared to the force required to transfer the housing 2 of the vacuum cleaner. Accordingly, the electric vacuum cleaner 1 may separately perform the operation of arranging the vacuum cleaner body 2 on the storage base 10 and the message operation of the dust separation / collection unit 26 and the dust collecting unit 47, and thereby the dust removal connecting pipe 35 and the intake connecting pipe 36 of the housing 2 the vacuum cleaner, the dust suction pipe 48 and the exhaust pipe 49 of the storage base 10 can be reliably connected.

In addition, according to the design of the electric vacuum cleaner 1, the vertical articulated support assembly 18 and the rollers 24 can facilitate handling of the vacuum cleaner body 2 and can reliably communicate the dust separation / collection unit 26 and the dust collection unit 47, while the main part 19 having the connecting pipe 35 to remove dust and the inlet connecting pipe 36, moves up or down or rotates.

Furthermore, according to the invention, dust accumulated in the vacuum cleaner body 2 is again collected in the storage base 10 each time the vacuum cleaner body 2 is stored in the storage base 10. Accordingly, dust collection in the vacuum cleaner 16 can be maintained for a long period of time.

Thus, the electric vacuum cleaner 1 according to the invention provides ease of handling of the vacuum cleaner body 2, provides stable attachment of the storage base 10 to the vacuum cleaner body 2 and is disconnected from it, and can maintain long-term dust collection in the vacuum cleaner body 2.
