Embodiments will be described below with reference to the accompanying drawings. The same reference numerals in each figure indicate the same or corresponding parts. In the present disclosure, overlapping descriptions are appropriately simplified or omitted. Note that the present disclosure can include any combination of configurations described in the following embodiments.

Embodiment 1.
The electric vacuum cleaner according to Embodiment 1 can be used in either a shawl form in which the main body of the cleaner is held by a belt and suspended, or a stick form.

First, the configuration in the form of a shoulder strap will be described. 1 to 4 are diagrams showing a state in which the vacuum cleaner according to Embodiment 1 of the present disclosure is worn over the shoulder. FIG. 1 is a schematic diagram of a cross section in a direction parallel to the longitudinal direction of the belt and perpendicular to the width direction, FIGS. 2 and 3 are perspective views, and FIG. It is a side view showing a state.

As shown in FIGS. 1 to 3, the vacuum cleaner 1 includes, for example, a substantially cylindrical vacuum cleaner main body 2. As shown in FIGS. As shown in FIG. 1, the cleaner body 2 separates dust from dust-laden air and delivers clean air. A cleaner main body 2 is provided with a dust collector 4 and an electric blower 5. - 特許庁The electric blower 5 generates an airflow to suck dust-containing air from the surface to be cleaned. The dust collection part 4 collects dust in the dust-containing air that has flowed into the cleaner main body 2 .

A primary filter 41 and a secondary filter 42 are arranged in the dust collecting section 4 . The primary filter 41 is, for example, a paper pack or cloth filter. The secondary filter 42 is a filter with a higher dust collection rate than the primary filter 41 . The secondary filter 42 is, for example, a HEPA filter (High Efficiency Particulate Air Filter) or a ULPA filter (Ultra Low Penetration Air Filter). The dust collecting part 4 can be removed from the cleaner main body 2 together with the primary filter 41 and the secondary filter 42 . The primary filter 41 and the secondary filter 42 can be removed from the dust collecting section 4, so that the dust collecting section 4, the primary filter 41 and the secondary filter 42 can be cleaned individually.

The cleaner body 2 has a connection pipe 6 , a suction port 7 and an exhaust port 8 . The suction port 7 is arranged at the longitudinal end of the cleaner body 2 . The suction port 7 is an opening for sucking dust-containing air into the cleaner body 2 . The exhaust port 8 is arranged on the side surface of the cleaner body 2 . The exhaust port 8 is an opening for sending out clean air from the cleaner body 2 .

The cleaner body 2 is provided with a battery 9 and a control section 10. - 特許庁The battery 9 can store electric power supplied from an external charging device via a charging terminal (not shown) of the cleaner body 2 . The control unit 10 drives the electric blower 5 with electric power stored in the battery 9 . An electrical wiring 11 including an electrical signal line and a power supply line is arranged in the connection pipe 6 . The electric wiring 11 can transmit electric power stored in the battery 9 and signals sent from the control unit 10 .

The center of gravity G of the cleaner main body 2 is located near the electric blower 5 and is located on the opposite side of the cleaner main body 2 from the suction port 7 with respect to the longitudinal center of the cleaner main body 2 .

When using the electric vacuum cleaner 1 in a shoulder-mounted form, a base 12 is attached to the cleaner main body 2 as shown in FIGS. 1 to 3 . The base 12 is a plate-shaped member, and is detachably attached to the main body 2 of the cleaner. The longitudinal length of the base 12 matches the longitudinal length of the cleaner body 2 . A removal button 13 is provided on the base 12 . When the removal button 13 is pushed, the fitting between the base 12 and the cleaner body 2 is released, and the base 12 is separated from the cleaner body 2 .

A first holding portion 14 is arranged at the end of the base 12 on the exhaust port 8 side, and a second holding portion 15 is arranged at the end on the suction port 7 side. Each of the two holding portions 14 and 15 is a member having a shape obtained by bending a part of both end sides of an elongated cylinder, and is made of, for example, a metal material. Each of the two holding portions 14 and 15 is arranged near the longitudinal end of the base 12 so that the central axis of the cylindrical shape is substantially perpendicular to the longitudinal direction, and the bent ends are respectively It is fixed to the base 12 . As a result, between the surface of the base 12 on which the two holding portions 14 and 15 are installed (hereinafter also referred to as “holding surface”) and each of the two holding portions 14 and 15, a gap penetrating in the longitudinal direction is provided. is formed.

The belt 3 is a ring-shaped resin fiber member having a circumference that is at least twice as long as the cleaner body 2 . The thickness of the belt 3 is such that the strength required to hold the cleaner body 2 can be ensured, and is specifically, for example, 0.2 cm. Also, the width of the belt 3 is slightly smaller than the width of the gap between each of the two holding portions 14 and 15 and the holding surface of the base 12 . A part of the belt 3 in the longitudinal direction is arranged along the longitudinal direction of the holding surface of the base 112 and passes through the gap formed between each of the two holding parts 14 and 15 and the base 12 . It is attached to the base 12 by being arranged in the . Since the belt 3 is slidably held by the two holding portions 14 and 15, the holding position of the belt 3 can be arbitrarily changed.

As an example, the vacuum cleaner main body 2 has an outer diameter of 8 cm and a longitudinal length of 28 cm. 5 cm, the belt 3 is, for example, 84 cm long, 5 cm wide and 0.2 cm thick.

A non-slip 20 is attached to the belt 3. The non-slip 20 is composed of an elastic member such as rubber. The slip stopper 20 is formed in a hollow cylindrical shape, and the belt 3 is passed through the inside. The non-slip 20 is movable with respect to the belt 3 , and the user can arbitrarily change the relative position of the non-slip 20 with respect to the belt 3 . When the user uses the electric vacuum cleaner 1 in the form of being worn on the shoulder as shown in FIG. 1, the user hangs the belt 3 on the shoulder with the cleaner main body 2 suspended by the belt 3 . At this time, by moving the non-slip 20 so that it abuts against the shoulder, the belt 3 is less likely to slip off the shoulder. When the cleaner body 2 is hung horizontally as shown in FIG. However, the frictional resistance between the shoulder and the non-slip 20 can suppress the inclination of the cleaner body 2 toward the center of gravity.

As shown in FIGS. 2 and 3, a swing suppression member 34 is installed on the holding surface side of the base 12 to which the two holding portions 14 and 15 are attached. The rocking suppressing member 34 is a member that suppresses rocking of the cleaner body 2 when the cleaner body 2 is used in the form of being worn on the shoulder. The swing suppressing member 34 includes a receiving portion 341 and a supporting portion 342 .

The receiving portion 341 is, for example, a plate-like member made of resin, and has a longitudinal length that is at least longer than the radius of the cleaner body 2 . The support portion 342 rotatably supports one end side of the receiving portion 341 on the base 12 . The receiving portion 341 is rotatable about 90 degrees clockwise and counterclockwise around the support portion 342 . However, the receiving portion 341 is locked at the position of the maximum rotation angle of approximately 90 degrees, and is configured not to rotate further.

FIG. 2 shows a state in which the receiving portion 341 is stored. As shown in FIG. 2 , the receiving portion 341 has its longitudinal direction oriented in the longitudinal direction of the base 12 and does not protrude from the base 12 and the cleaner body 2 in the width direction. stored in between.

On the other hand, FIG. 3 shows a state in which the receiving portion 341 is used. The receiving portion 341 is used while being rotated about 90 degrees around the supporting portion 342 . In this state, as shown in FIG. 3 , a portion of the receiving portion 341 on the leading end side protrudes outward from the cleaner body 2 in the width direction of the belt 3 . As shown in FIG. 4, when the cleaner main body 2 is used in the form of a shoulder strap sandwiched between the sides of the user, the receiving portion 341 abuts on the rear side of the upper arm of the user. As a result, the forward movement of the vacuum cleaner 1 is suppressed when the vacuum cleaner 1 is used in the form of being worn on the shoulder. Since the direction of rotation of the receiving portion 341 can be changed, the receiving portion 341 can be brought into contact with the rear of the upper arm regardless of whether the belt 3 is hung on the left or right shoulder.

The rocking suppression member 34 may have a configuration in which soft members made of a material softer than the receiving portion 341 are attached to two outer peripheral surfaces of the receiving portion 341 that are in contact with the upper arm and parallel to the longitudinal direction. Also, the soft member may be formed to be detachable. In this case, the user can attach the soft member to the side surface on the side that contacts the rear of the upper arm, depending on which of the left or right shoulder the user hangs the cleaner main body 2 on.

As shown in FIG. 4 , when the vacuum cleaner 1 is used in a shoulder-mounted form, a hose 21 is connected to the connection pipe 6 and a handle nozzle 22 is connected to the tip of the hose 21 . The handle nozzle 22 is a dogleg-shaped nozzle in which an air passage is formed. The handle nozzle 22 functions as part of the air passage and also as a handle held by the user.

An operating portion 23 is formed in the handle nozzle 22, and an electrical wiring 221 (see FIG. 7) is connected to the operating portion 23. As shown in FIG. Further, as shown in FIG. 1, the hose 21 is provided with electric wiring 211 inside. In a state in which the handle nozzle 22, the hose 21, and the connection pipe 6 are connected, the electric wiring 221 (see FIG. 7) of the handle nozzle 22 is connected to the electric wiring 11 via the electric wiring 211 of the hose 21. .

When the handle nozzle 22 , the hose 21 and the connecting pipe 6 are connected, the user can operate the vacuum cleaner 1 to start and stop from the operation portion 23 . A hand brush 24 is provided at the tip of the handle nozzle 22 . The hand brush 24 is rotatably provided at the tip of the handle nozzle 22 . When cleaning a desk or a high place, set the hand brush 24 so that the flocked bristles face forward.

The exhaust port 8 is formed on the side of the cleaner body 2 facing the base 12 . When the cleaner body 2 is used in a suspended state, the exhaust air sent out from the exhaust port 8 is sent downward. Therefore, it is possible to prevent the exhaust air from hitting the user even when the cleaning work is performed with the cleaner main body 2 hung on the shoulder.

By using the electric vacuum cleaner 1 in the form of being worn on the shoulder, it is possible to reduce the load due to the weight of the main body of the electric vacuum cleaner 1 on the hand. This can reduce hand and arm fatigue during cleaning work. In addition, the user's place-moving load is smaller when the cleaner body 2 is hung on the shoulder than when the cleaner body 2 is held by hand. Therefore, the burden of cleaning work on the user can be reduced.

In addition, when performing cleaning work in the shawl configuration, if the user leans forward, for example, and a force is applied to the cleaner body 2 to move it forward, the receiving part 341 is placed on the upper arm of the user. It abuts on the rear side to restrain the cleaner body 2 from moving forward. Further, when the user's posture is changed, the belt 3 receives force in the direction of coming off the shoulder, but the non-slip 20 can maintain the state of hanging on the shoulder without slipping due to the frictional resistance with the shoulder.

The electric vacuum cleaner 1 according to Embodiment 1 can be switched from the shoulder-mounted form to the stick form by removing the base 12 together with the belt 3 and replacing it with an attachment for the stick form. Regarding this, first, the order of attaching and detaching the base 12 and the cleaner main body 2 will be described below. 5 and 6 are views showing the vacuum cleaner 1 with the base 12 removed from the cleaner body 2, FIG. 5 being a side view and FIG. 6 being a perspective view.

As shown in FIGS. 5 and 6 , two hooks 121 are arranged at a distance from each other on the fitting surface, which is the surface facing the base 12 , of the cleaner body 2 . Two fitting holes 122 are formed at positions corresponding to the hooks 121 on the fitting surface of the base 12 facing the cleaner body 2 (that is, the surface of the base 12 opposite to the holding surface). ing. A latch 123 is positioned adjacent to each of the two fitting holes 122 in the base 12 . The latch 123 is biased in a direction to narrow the fitting hole 122 by an elastic body such as a spring inside the base 12 . The latch 123 is connected to the removal button 13 inside the base 12 and is configured to slide in the direction of widening the fitting hole 122 in conjunction with the depression of the removal button 13 .

A user can detach the vacuum cleaner body 2 and the base 12 by pressing the removal button 13 . More specifically, when the release button 13 is pushed, the two latches 123 slide to widen the opening of the fitting hole 122 . As a result, the engagement between the fitting hole 122 and the hook 121 is released. By separating the base 12 from the cleaner main body 2 in this state, the base 12 and the cleaner main body 2 can be separated.

On the other hand, when attaching the base 12 to the cleaner body 2 , the user aligns the fitting hole 122 with the position of the hook 121 and presses the base 12 against the cleaner body 2 . As a result, the latch 123 is pressed against the hook 121 and slides in the direction of widening the fitting hole 122 against the urging force of the spring or the like by the inclined surface of the hook 121 . When the hook 121 fits into the fitting hole 122 , the latch 123 slides in the direction of narrowing the fitting hole 122 . As a result, the hook 121 is fixed to the fitting hole 122 and the base 12 can be attached to the cleaner body 2 .

Next, an attachment part that is used in the stick state or shoulder-mounted state of the vacuum cleaner 1 will be described. FIG. 7 is a side view showing a state in which the cleaner main body 2 and attachment parts connectable to the cleaner main body 2 are separated.

The first pipe 25 is an attachment part that forms a cylindrical air passage. The first pipe 25 has a fitting portion 250 for attaching and detaching the cleaner body 2 . The configuration of the parts of the fitting portion 250 for attachment to and detachment from the cleaner body 2 is substantially the same as the configuration of the parts for attachment and detachment between the base 12 and the cleaner body 2 .

Specifically, two fitting holes 251 are provided at positions corresponding to the two hooks 121 of the cleaner body 2 on the side of the fitting portion 250 facing the cleaner body 2 . A latch 253 is provided adjacent to each of the two fitting holes 122 . The latch 253 is biased in a direction to narrow the fitting hole 122 by an elastic body such as a spring in the fitting portion 250 . A removal button 252 is arranged on one end face side of the fitting portion 250 in the longitudinal direction. The latch 253 is connected to the removal button 252 within the fitting portion 250 , and when the removal button 252 is pushed, it slides in the direction to widen the fitting hole 251 .

When attaching the cleaner body 2 to the first pipe 25 , the user aligns the hook 121 with the fitting hole 251 and presses the cleaner body 2 against the first pipe 25 . The latch 253 slides in the direction of widening the fitting hole 251 against the urging force of a spring or the like by the inclined surface of the hook 121 . When the hook 121 fits into the fitting hole 251 , the latch 253 slides in the direction of narrowing the fitting hole 251 to fix the hook 121 . Thereby, the cleaner main body 2 can be attached to the first pipe 25 .

Also, when the removal button 252 is pushed, the latch 253 slides to widen the opening of the fitting hole 251 . As a result, the engagement between the fitting hole 251 and the hook 121 is released. By separating the cleaner body 2 from the first pipe 25 in this state, the cleaner body 2 and the first pipe 25 can be separated.

A handle nozzle 22 , a second pipe 26 , or a relay duct 27 can be connected to the upper end side of the first pipe 25 . A suction port body 28 or a second pipe 26 can be connected to the lower end side of the first pipe 25 .

The relay duct 27 is an attachment part that connects the first pipe 25 to the connection pipe 6 of the cleaner body 2 and allows the air passage in the first pipe 25 and the suction port 7 to communicate with each other. The upper end side of the relay duct 27 can be connected to the handle nozzle 22 or the second pipe 26 . However, even in the connected state, the inside of the handle nozzle 22 or the second pipe 26 does not communicate with the air passage in the relay duct 27 . Note that this handle nozzle 22 is the same as the handle nozzle 22 connected to the hose 21 in the above-described shoulder-mounted form. However, when the handle nozzle 22 is used by being connected to the relay duct 27, the first pipe 25, or the second pipe 26, the hand brush 24 of the handle nozzle 22 is flocked backward (that is, the handle nozzle 22 side).

The suction port body 28 is an attachment part that has an opening on the bottom surface and sucks dust on the floor through the opening. The suction port body 28 includes a brush head 281 , an extension tube 282 and a hinge portion 283 . The brush head 281 is formed in a substantially rectangular parallelepiped shape, and is provided with a rotating brush 284 having flocked bristles on its outer periphery. The rotating brush 284 protrudes from an opening in the bottom surface of the brush head 281 and is driven by a rotating brush driving motor (not shown). The hinge portion 283 rotatably supports the extension tube 282 with respect to the brush head 281 .

The second pipe 26 is an attachment part that forms a cylindrical air passage. The upper end side of the second pipe 26 can be connected to the handle nozzle 22 or the lower end side of the first pipe 25 . Also, the lower end side of the second pipe 26 can be connected to the upper end side of the first pipe 25 , the relay duct 27 and the suction port body 28 .

As shown in FIG. 7, electrical wiring 254 and electrical wiring 261 are respectively arranged from the upper end to the lower end of the first pipe 25 and the second pipe 26, respectively. An electrical wiring 271 is arranged in the relay duct 27 . The electric wiring 271 is arranged from the upper end to the lower end, and is branched along the air path to the cleaner main body 2 side so that it can be connected to the electric wiring 11 on the cleaner main body 2 side. ing. An electrical wiring 221 is arranged inside the handle nozzle 22 . An electric wiring 285 is arranged inside the suction port body 28 . The electric wiring 285 is arranged from the upper end of the extension tube 282 to the brush head 281 via the hinge portion 283 . Electrical wiring 285 is connected to the rotating brush drive motor. The electrical wirings 254, 261, 271, 221, and 285 each comprise a power line and a signal line.

As described above, the vacuum cleaner 1 includes a plurality of detachable attachment parts. Depending on the method of connecting these attachment parts, the mode of use can be changed into a plurality of states. 8 to 10 are side views showing examples of how the vacuum cleaner is used.

In the example shown in FIG. 8, the handle nozzle 22, the first pipe 25, the second pipe 26, and the suction port body 28 are connected in order. The attachment part connected in this way can be used by being attached to the tip of the hose 21 when using the vacuum cleaner 1 in the form of a shoulder strap. That is, the end of the handle nozzle 22 of the attachment part connected as shown in FIG. 8 is connected to the hose 21 . As a result, the air passage from the bottom opening of the suction port body 28 to the suction port 7 of the cleaner main body 2 is communicated in a shoulder-mounted form.

Further, when the handle nozzle 22, the first pipe 25, the second pipe 26, and the suction port body 28 are connected, the electric wirings 221, 254, 261, and 285 provided respectively are connected. . The electric wiring 221 is connected to the electric wiring 11 of the cleaner main body 2 via the electric wiring 211 of the hose 21 . Electric power is thereby supplied to the rotating brush drive motor of the inlet body 28 . Then, the operation unit 23 drives and stops the rotating brush according to the operation and stop of the electric vacuum cleaner 1 .

By using the attachment shown in FIG. 8, even when the electric vacuum cleaner 1 is used in a shoulder-mounted form, a flat portion such as a floor surface relatively distant from the user can be cleaned by the suction port 28. can be done. In the shawl form, the load of the main body weight of the electric vacuum cleaner 1 on the hand can be kept small. Therefore, the movement of the suction port body 28 becomes easy, and the cleaning work can be performed smoothly.

It should be noted that the attachment part can also be used in a form in which the first pipe 25 or the second pipe 26 in the example of FIG. 8 is removed. That is, by connecting the handle nozzle 22, the first pipe 25 or the second pipe 26, and the suction port body 28, and connecting the handle nozzle 22 to the tip of the hose 21, it can be worn on the shoulder as well. , the electric vacuum cleaner 1 can be used for cleaning a floor surface or the like.

Furthermore, the attachment part can also be used in a form in which both the first pipe 25 and the second pipe 26 in the example of FIG. 8 are removed. That is, the handle nozzle 22 can be used by directly connecting the suction port body 28 . This allows the user to hold the handle nozzle 22 and easily clean stairs, sofas, and the like.

As described above, in the electric vacuum cleaner 1 according to Embodiment 1, the swinging motion of the cleaner body 2 is suppressed by the swinging motion suppression member 34 even when the user changes the posture. Therefore, by changing the attachment member according to various usage patterns, a wider range of cleaning can be easily carried out in the form of being worn on the shoulder.

The example shown in FIG. 9 is an example of use of the vacuum cleaner 1 in a stick form with an upper center of gravity. When the vacuum cleaner 1 is used in a stick form, the cleaner body 2 is attached to the first pipe 25 as shown in FIG. 2 connecting pipes 6 are connected. In the case of a stick form with a high center of gravity, the handle nozzle 22 is connected to the upper end of the relay duct 27 . A second pipe 26 is connected to the lower end of the first pipe 25 , and a suction port body 28 is connected to the lower end of the second pipe 26 . As a result, the air passage from the bottom opening of the suction port body 28 to the suction port 7 of the cleaner body 2 communicates.

Also, due to this connection, the electric wiring 271, the electric wiring 254, the electric wiring 261, and the electric wiring 285 are connected to the electric wiring 11 of the cleaner body 2, and the electric wiring 271 and the electric wiring 221 are connected. As a result, it is possible to operate and stop the electric vacuum cleaner 1 and to drive and stop the rotating brush from the operation unit 23 .

As a result, cleaning work can be performed in a stick form with a high center of gravity. In the stick form, cleaning work can be performed with the cleaner main body 2 farther away from the body than in the shoulder form. In addition, in the stick form with the upper center of gravity, the suction port body 28 can be easily moved.

Also, the example shown in FIG. 10 is an example of using the vacuum cleaner 1 in a stick form with a lower center of gravity. When the vacuum cleaner 1 is in a stick form with a low center of gravity position, the second pipe 26 is attached to the upper end of the relay duct 27 in a state where the cleaner body 2, the first pipe 25 and the relay duct 27 are attached. A handle nozzle 22 is connected to the upper end of the second pipe 26 . A suction port body 28 is connected to the lower end of the first pipe 25 . As a result, the air passage from the bottom opening of the suction port body 28 to the suction port 7 of the cleaner body 2 communicates.

Also, by this connection, the electric wiring 271, the electric wiring 254, and the electric wiring 285 are connected to the electric wiring 11 of the cleaner body 2, and the electric wiring 271, the electric wiring 261, and the electric wiring 221 are connected. . As a result, it is possible to operate and stop the electric vacuum cleaner 1 and drive and stop the rotating brush from the operation unit 23 .

As a result, the vacuum cleaner 1 can be cleaned in a stick form with a low center of gravity. In the stick form with the lower center of gravity, the operating load of the handle nozzle 22 can be reduced.

The electric vacuum cleaner 1 can also be used in a form in which the second pipe 26 is removed from the form shown in FIG.

The electric vacuum cleaner 1 according to the present embodiment can be easily switched between the shawl form and the stick form. Also, attachment parts such as the base 12 and the first pipe 25 can be removed from the cleaner body 2 . Therefore, it is possible to increase the options of storage forms.

Embodiment 2.
11 to 13 are diagrams showing a state in which the electric vacuum cleaner according to Embodiment 2 is worn over the shoulder or wrapped around the waist. FIG. 11 is a side view, and FIGS. 12 and 13 are perspective views. Vacuum cleaner 1 according to Embodiment 2 has the same configuration as vacuum cleaner 1 according to Embodiment 1, except that it has third holding portion 16 and buckle 18 . Parts that are the same as or correspond to those of the electric vacuum cleaner 1 according to Embodiment 1 are given the same reference numerals, and explanations thereof are simplified or omitted.

In this embodiment, the belt 3 is provided with a buckle 18 . 11 and 12 show the state in which the buckle 18 is fitted, and FIG. 13 shows the state in which the buckle 18 is unfitted. As shown in FIG. 13, the buckle 18 consists of a pair of parts that can be connected and separated. One of the pair of parts has a fitting claw 182 and the other has a fitting part that fits with the fitting claw 182 . The buckle 18 is separated by pushing and pulling the fitting claw 182 . By pushing the fitting claw 182 into the fitting portion, the pair of components are fitted together and the buckle 18 is connected.

Both ends of the belt 3 are connected to the buckles 18, respectively. When the buckle 18 is connected, the belt 3 becomes looped. As shown in FIG. 13 , both ends of the belt 3 are folded back through holes 181 of the buckle 18 and fixed to the buckle 18 . A planar fastener is arranged on the inner surface of the folded portion 31 at the end of the belt 3 (that is, the surface that contacts the belt 3), and the area of the belt 3 that contacts the folded portion 31 has a receiving side. A planar fastener is placed. The folded-back portion 31 is fixed to the planar fastener on the surface of the belt 3 facing the folded-back state. By adjusting the length of the folded portion 31, the length of the looped portion of the belt 3, ie, the length of the portion that holds the cleaner body 2, can be adjusted.

The length of the belt 3 according to the second embodiment is obtained by the following equation based on the standard circumference of the belt 3, the standard length of the folded portion 31 when the standard circumference is used, and the length of the buckle 18. It is determined.
Belt length = standard perimeter + folded length x 2 - buckle length

For example, if the length of the folded portions 31 at both ends of the belt 3 is 8 cm, the length of the buckle 18 is 10 cm, and the circumference of the belt 3 is 84 cm as in the first embodiment, then the length of the belt 3 is The height is 84+8×2−10=90 cm. Further, in this example, if the length of the folded portions 31 at both ends is, for example, 4 cm, the circumference of the annular portion including the buckle 18 is 92 cm. If the length of the folded portions 31 at both ends is 12 cm, for example, the circumferential length of the annular portion including the buckle 18 is 76 cm. By adjusting the length of the folded portion 31 in this manner, the circumferential length of the annular belt 3 can be adjusted.

The electric vacuum cleaner 1 of Embodiment 2 can be used by switching from the shoulder-mounted form to the waist-wrapped form. FIG. 14 is a side view showing how the electric vacuum cleaner 1 is used in the loincloth form. When the user attaches the cleaner main body 2 to the waist, the user first separates the buckle 18 by pushing the fitting claw 182 of the buckle 18 and pulling it away from the fitting portion. Next, hold both ends of the belt 3 and put the vacuum cleaner main body 2 on the waist. In this state, the fitting claw 182 of the buckle 18 is pushed into the fitting portion to connect the buckle 18, and the belt 3 is looped. A hose 21 is attached to the connection pipe 6, and a handle nozzle 22 is connected to the tip of the hose 21, in the same manner as in the use of the shoulder strap. In this way, by providing the belt 3 with the buckle 18, it is possible to easily switch between the shoulder-wrapped form and the waist-wrapped form.

By using the electric vacuum cleaner 1 in a waist-wrapped form, the load of the body weight of the electric vacuum cleaner 1 applied to the user's hand can be reduced. Therefore, hand and arm fatigue during cleaning work can be reduced. In addition, the user's positional movement load when the cleaner body 2 is worn on the waist is smaller than the positional movement load when the cleaner body 2 is held by hand or slung over the shoulder. Therefore, cleaning work can be made easier.

Further, as shown in FIGS. 11 to 13, the vacuum cleaner 1 according to Embodiment 2 has a third holding portion 14 and a second holding portion 15 of the base 12. It has a holding portion 16 . The third holding portion 16 is made of flexible material. The third holding portion 16 is a member for holding the belt 3 on the base 12 between the first holding portion 14 and the second holding portion 15 . A connecting member 17 is arranged in the third holding portion 16 . The connecting member 17 switches the third holding part between a connected state and a separated state.

15 to 17 are diagrams showing a state in which the belt 3 is held by the third holding portion 16 when the electric vacuum cleaner 1 is used in a shoulder-mounted form. FIGS. 15 and 16 are perspective views, and FIG. , a side view.

For example, when switching the electric vacuum cleaner 1 from the waist-wrapped form of FIG. Then, the belt 3 is shifted in the direction in which the buckle 18 approaches the first holding portion 14 . At this time, the belt 3 can be shifted while being slid on the holding portions 14 and 15 while being held by the two holding portions 14 and 15 . After that, the belt 3 is sandwiched by the third holding portion 16 and the connecting member 17 is connected.

In the shawl configuration, the belt 3 is folded back at the first holding portion 14 and held by the third holding portion 16, as shown in FIG. That is, the portion of the belt 3 between the first holding portion 14 and the third holding portion 16 is overlapped and held along the base 12 . In this state, the circumferential length of the portion of the belt 3 that holds the cleaner body 2 is the length of the folded portion (that is, from the first holding portion 14 to the third holding portion 14) from the circumferential length of the annular portion including the buckle. twice the length to the end of the portion 16 on the side of the second holding portion 15). For example, in the above example where the circumference of the annular portion is 84 cm, if the length of the folded portion of the belt 3 by the third holding portion 16 is 24 cm, the circumference of the portion that holds the cleaner body 2 is 84 cm. 24 = 60 cm.

When the user lifts the belt 3 in the state shown in FIG. 15, the cleaner main body 2 is supported and lifted by the second holding portion 15 and the third holding portion 16 on the cleaner main body 2 . At this time, since the third holding portion 16 is arranged close to the center of gravity G, the cleaner body 2 tilts in a direction in which the third holding portion 16 and the first holding portion 14 side are lowered. Since the ring-shaped belt 3 is slidably supported by the first to third holding portions 14, 15, and 16, the vertex of the belt 3 when lifted is perpendicular to the center of gravity G of the cleaner body 2. This is the position near the upper part. Therefore, the non-slip 20 is moved near this vertex. In this state, as shown in FIG. 17, the non-slip 20 is put on the shoulder and the belt 3 is put on the shoulder. As a result, the cleaner body 2 is stabilized in a state in which the second holding portion 15 side is tilted upward.

In the electric vacuum cleaner 1 according to the present embodiment, the belt 3 is supported by the third holding portion 16 in a shoulder-mounted configuration, so that the peripheral length of the belt 3 at the portion that holds the cleaner main body 2 is short. In addition, the cleaner main body 2 is tilted so that the position of the cleaner main body 2 is close to the side of the user. Therefore, the user can hold the cleaner main body 2 between the trunk and the upper arm, thereby suppressing the swinging of the cleaner main body 2 even when the user changes his/her posture. can be done. In addition, since the circumference of the belt 3 is short and the swinging of the cleaner body 2 is suppressed, the belt 3 is less likely to slip off the user's shoulder.

In addition, in the shawl configuration, the receiving portion 341 of the rocking suppression member 34 can be rotated to protrude from the base 12 to the rear side of the upper arm. Thereby, the swing suppressing member 34 can be brought into contact with the rear side of the upper arm. Therefore, even when the user leans forward during cleaning work, the cleaner body 2 can be prevented from moving forward, thereby preventing a decrease in cleaning efficiency due to swinging of the cleaner body 2. can be suppressed.

Compared to the cleaning work in the waist-wrapped form, the movement of the arm is restricted in the cleaning work in the shoulder-wrapped form because the cleaner main body 2 is positioned around the user's shoulders. On the other hand, the work of putting the belt 3 on the shoulder is easier than the work of wrapping the belt 3 around the waist. Moreover, the work for removing the electric vacuum cleaner 1 from the body after use is easier in the shoulder-hung configuration than in the waist-wrapped configuration. In this respect, according to the electric vacuum cleaner 1 of Embodiment 2, since it is possible to easily switch between the waist-wrapped form and the shoulder-wrapped form, it is possible for the user to select the most suitable one according to the situation such as the content of the cleaning work and the work time. The electric vacuum cleaner 1 can be used by freely selecting any form.

The position of the third holding portion 16 of the second embodiment is fixed with respect to the base 12, and the length from the first holding portion 14 to the third holding portion 16 is fixed. ing. However, the third holding part 16 may be configured so that its position relative to the base 12 can be changed. By changing the position of the third holding part 16 with respect to the base 12, the circumferential length of the belt 3 at the part holding the cleaner body 2 can be adjusted. Also, the third holding part 16 may have a function of adjusting the length. By adjusting the length of the third holding portion 16, the distance between the portion of the belt 3 held by the third holding portion 16 and the base 12 can be adjusted. This makes it possible to adjust the circumferential length of the annular portion of the belt 3 worn over the shoulder.

Further, the belt 3 is passed through a gap between the base 12 and the first holding portion 14 and the second holding portion 15 to be held. Therefore, the holding position of the belt 3 with respect to the base 12 can be arbitrarily changed. This allows the user to adjust the buckle 18 so that it does not hit the shoulder.

Embodiment 3.
18 and 19 are diagrams showing a state when the electric vacuum cleaner according to Embodiment 3 is used in a shoulder-mounted form, FIG. 18 being a perspective view and FIG. 19 being a side view. The vacuum cleaner 1 according to Embodiment 3 is the same as the vacuum cleaner 1 according to Embodiment 2, except that the base 12 does not have the swing suppressing member 34 and the belt 3 is provided with the swing suppressing member 35. They have the same configuration. Parts that are the same as or correspond to those in the first or second embodiment are denoted by the same reference numerals, and explanations thereof are simplified or omitted.

Swing suppressing member 35 of vacuum cleaner 1 according to Embodiment 3 includes receiving portion 351 and supporting portion 352 . The receiving portion 351 is attached to the buckle 18 by a support portion 352 at its central portion. The receiving portion 351 is a plate-like member made of resin or the like. The receiving portion 351 is rotatable around the supporting portion 352 . The receiving portion 351 can be used by switching between a longitudinal direction along the belt 3 and a longitudinal direction perpendicular to the circumferential direction of the belt 3 by rotation.

18 and 19 show a state in which the receiving portion 351 is perpendicular to the circumferential direction of the belt 3. FIG. When the vacuum cleaner main body 2 is used in the form of a shoulder strap and is sandwiched between the sides of the user, the receiving portion 351 projects perpendicularly to the circumferential direction of the belt 3 so that the receiving portion 351 can be worn by the user. It abuts in both directions on the back and the back of the upper arm. As a result, even when the cleaner body 2 receives a forward force due to the user changing his/her posture, the receiving part 351 contacts both the back and the rear of the upper arm of the user. Therefore, compared with the rocking suppression member 34 of the electric vacuum cleaner 1 according to Embodiments 1 and 2 described above, the forward movement suppression effect of the cleaner body 2 can be enhanced.

Embodiment 4.
FIG. 20 is a perspective view showing a state in which the electric vacuum cleaner 1 according to Embodiment 4 is used in the form of being worn over the shoulder. The electric vacuum cleaner 1 of Embodiment 4 has the same configuration as the electric vacuum cleaner 1 of Embodiment 3, except that a swing suppressing member 36 is further provided. Parts that are the same as or correspond to those of the first to third embodiments are denoted by the same reference numerals, and explanations thereof are simplified or omitted.

The rocking suppression member 36 includes a string body 361 , an upper hook 362 , a lower hook 363 and a length adjusting portion 364 . The upper hook 362 and the lower hook 363 are connected to ends of the string 361 respectively. The upper hook 362 and the lower hook 363 can be attached to and detached from the two holders 14 and 15 . A part of the cord body 361 is stored in the length adjusting portion 364 . The length adjusting portion 364 has fixing means and releasing means (not shown), and can thereby adjust the length of the cord body 361 .

When the user uses the electric vacuum cleaner 1 in the form of a shoulder strap, first, the upper hook 362 is removed from the second holding portion 15, and the lower hook 363 is attached to the first holding portion 14. , put the belt 3 on the shoulder. Next, the cord body 361 is routed over the waist and over the shoulder on the side where the belt 3 is not worn. Then, the upper hook 362 is attached to the second holding portion 15 . At this time, it is desirable to previously adjust the length of the string 361 by the length adjusting section 364 to such an extent that the string 361 does not become slack.

By rotating the swing suppressing member 36 from the waist to the shoulder of the user, the forward movement of the cleaner body 2 is suppressed even if the user is bent forward. Therefore, according to the electric vacuum cleaner 1 according to the fourth embodiment, even when the user changes his/her posture during the cleaning work in the shoulder-mounted configuration, the swing suppressing member 35 and the swing suppressing member 36 perform cleaning. Swinging of the machine body 2 can be effectively suppressed, and cleaning work can be facilitated.

Embodiment 5.
21 and 22 are diagrams showing how the electric vacuum cleaner 1 according to Embodiment 5 is used in a shoulder-mounted configuration. FIGS. 21 and 22 are perspective views, and FIG. It is a figure which shows typically the cross section perpendicular|vertical with respect to.

The swing suppressing member 46 is composed of a receiving portion 461 and a supporting portion 462 . The support portion 462 rotatably supports the end of the receiving portion 461 on the side closer to the connecting pipe 6 in the longitudinal direction to the base 12 . The receiving portion 461 is a member made of resin, for example, and is a plate-shaped member that is curved so as to swell toward the base 12 side.

FIG. 21 shows a state in which the receiving portion 461 is stored. As shown in FIG. 21, the receiving portion 461 is in a state in which its longitudinal direction is along the longitudinal direction of the base 12 when stored. The receiving portion 461 is configured to be rotatable about 90 degrees in both clockwise and counterclockwise directions around the supporting portion 462 . FIG. 22 shows a state in which the receiving portion 461 is rotated counterclockwise by about 90°. When the receiving portion 461 is used when the electric vacuum cleaner 1 is worn over the shoulder, as shown in FIG. It is in a state of protruding from the side surface of 2.

FIG. 23 shows a state in which the electric vacuum cleaner 1 is worn over the user's shoulder with the connection pipe 6 of the cleaner body 2 facing downward and forward of the user. When mounted in this manner, the cleaner body 2 abuts on the rear side of the user's upper arm. Further, since the center of gravity G of the cleaner body 2 is located behind the shoulder, the cleaner body 2 can be stably used by being pressed against the rear side of the upper arm. Further, at this time, the receiving portion 461 can be brought into contact with the rear side of the upper arm by setting the receiving portion 461 to a state in which it is used to protrude outward from the base 12 . Since the receiving portion 461 is formed in a curved shape, a large contact area between the upper arm rear portion and the receiving portion 461 can be ensured. As a result, the cleaner main body 2 can be kept in a state in which it is difficult to come off from the upper arm. Thereby, the user can use the electric vacuum cleaner 1 with good usability even when the movement during the cleaning work is large.

In the vacuum cleaner 1 according to the present embodiment, as shown in FIGS. 21 to 23, two belts 3 are stacked between the first holding portion 14 and the second holding portion 15. kept in a state. When held in this way, the buckle 18 is positioned on the outside of the belt 3 (i.e., the side opposite to the cleaner body 2), and the anti-slip 20 is positioned on the inner side of the belt 3 (i.e., on the cleaner body 2). facing side). 21-23 and the looped belt 3 with shoulders inside as shown in FIG. It is configured such that it can be moved through either the holding portion 14 or the second holding portion 15 , or the anti-slip 20 is configured to be detachable from the belt 3 .

The dust collection case 471 and the filter part 472 can be removed from the cleaner main body 2 and can be cleaned individually.

When the electric blower 5 is driven, dust-containing air is sucked into the opening 476 from the suction port 7 via the air passage 477 and is swirled by the separation swirl portion 474 . As a result, the dust in the dust-laden air is separated on the wall surface side of the separation turning section 474 by centrifugal force, moves to the dust collecting section 475 and stays there. The HEPA filter 479 collects fine dust that has passed through the cylindrical filter 478 without being completely separated by the separation turning part 474 . The clean air passing through the HEPA filter 479 passes through the electric blower 5 and is sent out from the exhaust port 8 .

When the dust collector 47 is a cyclone dust collector as in the vacuum cleaner 1 according to this embodiment, the dust collected by the dust collector 475 does not fall downward from the suction port 7 . Further, as shown in FIG. 23 , the dust collector 475 is positioned below the separation turning section 474 by holding the connection pipe 6 facing downward and forward. As a result, the movement of the collected dust to the outside of the dust collecting portion 475 is suppressed, and the electric vacuum cleaner 1 can be held and used hygienically.

In addition, in the configuration in which the connecting pipe 6 faces downward and forward, the connecting position of the hose 21 with the cleaner main body 2 is lowered, so that the operation load of the handle nozzle 22 at the tip of the hose 21 is reduced during cleaning work, and usability is improved. .
