Description
The present application is based on and has priority rights from Japanese patent application 2018-215825 (application date: 11/16/2018). This application incorporates by reference the entirety of this application.
Technical Field
Embodiments of the present invention relate to an electric vacuum cleaner including a grip portion gripped by a user.
Background
A stick-type vacuum cleaner is known in which a user grips a grip portion and moves a suction port body at a tip portion on a floor surface. In the case of a stick-type electric vacuum cleaner in which a vacuum cleaner body is held by a grip portion, a load of a heavy object such as an electric blower, a secondary battery, or a dust collecting portion provided in the vacuum cleaner body is applied to a hand when the grip portion is operated. Therefore, when a large moment is generated by a heavy object, particularly when the grip portion is twisted, such as when the direction of travel of the suction port body is changed, the load on the user's hand becomes large.
In contrast, in an electric vacuum cleaner in which a suction port body is connected to a cleaner body via an extension pipe arranged along the cleaner body, a grip pipe having a grip portion, and a hose, there is known an electric vacuum cleaner in which the cleaner body is connected to the extension pipe via a rotation mechanism, and a twisting motion of the cleaner body with respect to the grip portion is not followed. However, in the case of this configuration, since the cleaner main body greatly protrudes laterally with respect to the axis of the extension pipe extending from the grip portion to the suction port body, the electric vacuum cleaner is likely to swing with respect to a motion other than a twisting motion such as a pushing and pulling motion of the grip portion, and it is difficult to reduce a load applied to the hand of the user.
Disclosure of Invention
An object of the present invention is to provide an electric vacuum cleaner capable of reducing a load applied to a hand of a user gripping a grip portion during operation.
The electric dust collector of the embodiment comprises a holding part, a suction inlet body, a rigid body, a weight and a dust collecting device. The grip portion is gripped during the cleaning operation. The suction port body moves on the surface to be cleaned during the cleaning operation. The rigid body connects the grip portion and the suction port body. The weight object has a sliding portion with respect to the rigid body when the grip portion performs a predetermined operation, and is arranged so as not to follow the rigid body. In the dust collecting device, an inlet for dust-containing air sucked from the suction inlet body is provided on the suction inlet body side, and an outlet for air from which dust is separated is provided on the grip portion side.
According to the above configuration, the load applied to the hand of the user gripping the grip portion during operation can be reduced.

The power supply unit 15 is housed in the second body portion 18, for example, at a position close to the lower side of the grip portion 2, and is arranged in parallel in the front-rear direction with respect to the electric blower 13 and the control unit 14. That is, in the present embodiment, the power supply unit 15 is disposed on the lower side with respect to the rigid body 6. That is, the power supply unit 15 is disposed on the same side as the electric blower 13 and the control unit 14 when viewed from the rigid body 6. The arrangement of the power supply unit 15 in the case unit 4 is not limited to this, and the power supply unit can be appropriately arranged by utilizing the space of the case unit 4.
In the present embodiment, the power supply unit 15 uses, for example, a secondary battery. That is, the electric vacuum cleaner 1 of the present embodiment is a cordless electric vacuum cleaner 1 with a built-in power supply. The power supply unit 15 of the present embodiment is configured as a battery pack including a plurality of batteries and a substrate. Therefore, the power supply unit 15 can be said to be a heavy object. The power supply unit 15 is not limited to the secondary battery, and may be a cord reel (cord reel) device for obtaining power from an external power supply. Even in the case of the take-up reel device, the power supply unit 15 can be said to be a heavy object because it includes a take-up reel, a coil spring, a power supply line, and the like.
The first body 17 is a portion through which the rear side of the rigid body 6 is inserted. The first body 17 is positioned forward relative to the grip 2. In the present embodiment, the first body portion 17 is formed as an inclined portion that is inclined upward from the rear portion toward the front portion.
The second body portion 18 is coupled to the rear portion of the first body portion 17 and is disposed along the front-rear direction at a position below the grip portion 2. The second body portion 18 extends rearward relative to the first body portion 17. The grip portion 2 is positioned above the second body portion 18.
The connection receiving portion 19 is connected to the front portion of the first body portion 17 and positioned in front of the grip portion 2. The connection receiving portion 19 has a shape portion to which the dust collecting device 5 is connected and which rises upward from the first body portion 17, and a shape portion which extends and protrudes forward from the first body portion 17.
The dust collecting device 5 separates and collects dust from the dust-containing air sucked from the suction inlet body 3 by the negative pressure generated by the driving of the electric blower 13. In the dust collecting device 5, the introduction port 21 for dust-containing air and the discharge port 22 for air from which dust has been separated are disposed on the same side of the dust collecting device 5 and arranged side by side in the longitudinal direction of the dust collecting device 5. The inlet port 21 communicates with the inlet port body 3, and the outlet port 22 communicates with the suction side of the electric blower 13. The dust collecting device 5 of the present embodiment is detachable from the box body 4 at the position of the connection receiving portion 19. The dust collecting device 5 of the present embodiment is disposed above the rigid body 6, and the dust collecting device 5 is located in a position close to the front of the grip portion 2 and on the opposite side of the electric blower 13, the control portion 14, and the power supply portion 15 when viewed from the rigid body 6. In the illustrated example, the dust collecting device 5 is disposed with its longitudinal direction along the front-rear direction of the electric vacuum cleaner 1, the inlet 21 is located on the suction port body 3 side, i.e., on the front side of the dust collecting device 5, and the outlet 22 is located on the grip 2 side, i.e., on the rear side of the dust collecting device 5. The arrangement of the dust collection device 5 is not limited to this, and for example, the dust collection device 5 may be arranged such that the longitudinal direction thereof is along the vertical direction of the electric vacuum cleaner 1.
In the present embodiment, a cyclone type dust separating and collecting unit is used as the dust collecting device 5. In the dust collecting device 5 of the present embodiment, a plurality of cyclone units, filters, and the like formed of a rigid body such as a synthetic resin are disposed. Therefore, the dust collecting device 5 can be said to be a heavy object. In the present embodiment, the inlet 21 is formed on the front side, which is one end side, and the outlet 22 is formed on the rear side, which is the other end side. The dust collecting device 5 is not limited to the cyclone type, and other known dust collecting devices 5 such as a filter type and an inertial type can be applied.
The rigid body 6 is formed long in the front-rear direction. In the present embodiment, the rigid body 6 includes an extension pipe 27 as a pipe body connected to the suction port body 3, and a connecting portion 28 connecting the extension pipe 27 and the grip portion 2.
The extension pipe 27 is formed in a long straight pipe shape having an axis a in the front-rear direction, and serves as an air passage for sucking dust into the dust collector 5. One end side, i.e., the distal end portion of the extension pipe 27 is connected to the connection pipe 11 of the suction port body 3. Further, a sliding portion 30 is provided at the rear end portion of the extension pipe 27. The sliding portion 30 slides by the movement of the grip portion 2, and causes predetermined movement of the weight such as the electric blower 13, the power supply portion 15, and the dust collecting device 5, which are located in the casing portion 4, with respect to the grip portion 2 to be non-follow. Here, "not follow" means not follow only a predetermined movement of the grip portion 2, and does not mean that the weight such as the electric blower 13, the power supply portion 15, and the dust collector 5 is fixed and does not move. The sliding unit 30 of the present embodiment sets the direction switching operation, for example, the twisting operation, of the weight such as the electric blower 13, the power supply unit 15, and the dust collector 5 with respect to the grip unit 2 that changes the direction of travel of the suction port body 3 as non-follow-up. At this time, the weight slightly fluctuates due to the friction of the sliding portion 30, but does not follow the direction switching operation of the grip portion 2. The sliding portion 30 is located on the axis a of the extension tube 27. The sliding portion 30 is connected to the inlet 21 of the dust collecting device 5. In the present embodiment, the sliding portion 30 is disposed at a lower front portion of the dust collecting device 5. In the illustrated example, the sliding portion 30 includes a first sliding portion 32 having a cylindrical shape integrally formed with the extension pipe 27 and a second sliding portion 33 having a cylindrical shape integrally formed with the housing portion 4, coaxially in the front and rear direction, and the first sliding portion 32 and the second sliding portion 33 are slidable in the axial direction relative to each other. The slider 30 is a part of an air passage connecting the suction port body 3 and the dust collector 5. The sliding portions of the first sliding portion 32 and the second sliding portion 33 are sealed by a sealing member so as to be slidable with respect to each other. The second slider 33 has an air passage bent upward inside thereof and is connected to the inlet 21 of the dust collector 5. The inlet 21 of the dust collecting device 5 is positioned between the suction port body 3 and the grip 2. In the illustrated example, the inlet 21 is located slightly above the axis a of the extension pipe 27 of the rigid body 6 connecting the suction port body 3 and the grip portion 2. The sliding portion 30 is not limited to the configuration of the first sliding portion 32 and the second sliding portion 33, and may be, for example, a configuration including three or more cylindrical members slidably provided, or may be a cylindrical configuration directly connected to the inlet 21 of the dust collecting device 5 slidably.
One end, i.e., a front end portion, of the connecting portion 28 is connected to the other end, i.e., a rear end portion, of the extension pipe 27. The connecting portion 28 branches off from the front of the sliding portion 30 with respect to the extension pipe 27, and the rear end portion on the other end side is connected to the grip portion 2 while bypassing the sliding portion 30. In the present embodiment, the connection portion 28 includes a bypass portion 35 that bypasses the slide portion 30, and a connection portion 36 that is connected to the grip portion 2. The detour portion 35 is formed in an コ shape, for example, when viewed in the width direction, and is bent so as to bypass the slide portion 30 at the lower side. The connection portion 36 is connected to the bypass portion 35 and is formed in a linear shape coaxial or substantially coaxial with the extension pipe 27. That is, the coupling portion 36 is disposed along the axis a of the extension pipe 27. The connecting portion 36 is inserted through the first body portion 17 of the box portion 4 in the front-rear direction, and the rear portion is connected to the grip portion 2.
A portion where the first body portion 17 is inserted into the coupling portion 36 is referred to as an insertion portion 38, and this will be described. The insertion portion 38 is provided as a cylindrical hole 39 formed through the first body portion 17, and the inner surface side of the hole 39 of the first body portion 17 is formed to be slidable with respect to the insertion portion 38. The through-going portion 38 is located on the axis a of the extension tube 6. Since the second body portion 18 including the secondary battery as the power supply portion 15 is heavy, when the grip portion 2 is twisted, the insertion portion 38 of the connection portion 36 slides with respect to the first body portion 17.
The portion through which the insertion portion 38 is inserted has a hollow shape that divides the first body portion 17 into two ways, and may have a space with the inner surface of the first body portion 17. That is, the insertion portion 38 may not slide with the first body portion 17.
Here, fig. 2 shows a connection structure of the rigid body 6 and the grip portion 2. Fig. 2 is an explanatory view of the rear side of the electric vacuum cleaner 1. In fig. 2, for the sake of explanation, when the grip portion 2 is twisted, the non-following portion is indicated by hatching. In the figure, P1 and P2 are sliding portions, respectively. The sliding portion P1 is a sliding portion between the first sliding portion 32 and the second sliding portion 33, and the sliding portion P2 is a sliding portion between the insertion portion 38 and the hole 39 of the case portion 4. When the grip portion 2 is twisted, the connection portion 28 and the extension pipe 27 constituting the rigid body 6 and the suction port body 3 (fig. 1) connected to the extension pipe 27 move (follow) in accordance with the operation, and the second sliding portion 32 sliding with the rigid body 6 via the sliding portions P1 and P2, the dust collecting device 5, the box portion 4, the electric blower 13 housed in the box portion 4, and the power supply portion 15 (fig. 1) do not follow the operation.
Fig. 3 is a schematic view of the air passage on the rear side of the electric vacuum cleaner 1. The air passage is formed, as shown by arrow X in the figure, so as to communicate with the dust collecting device 5 from the extension pipe 27 and the sliding portion 30 through the inlet port 21, communicate with the first body 17 of the case portion 4 from the outlet port 22 of the dust collecting device 5, communicate with the suction side of the electric blower 13 through the inside of the case portion 4 while avoiding the insertion portion 38, and discharge the air from the exhaust side of the electric blower 13 to the outside of the case portion 4 through the exhaust port of the case portion 4. In the configuration avoiding the insertion portion 38, the air passage may be formed on the side passing through the insertion portion 38, or may be formed so as to be divided into two paths on both sides of the insertion portion 38 and merged on the downstream side.
When cleaning is performed by the electric vacuum cleaner 1 of the present embodiment, the user grips the grip portion 2, operates the hand-side operation portion 8 to start the electric vacuum cleaner 1, and moves the suction port body 3 on the surface to be cleaned, thereby sucking dust on the surface to be cleaned together with air by the negative pressure generated by the driving of the electric blower 13. When the suction port body 3 is moved in the front-rear direction, i.e., in the longitudinal direction of the rigid body 6 by the operation of pushing and pulling the grip portion 2, the box portion 4 and the dust collecting device 5 are also moved together with the grip portion 2. That is, the weight such as the electric blower 13, the power supply unit 15, and the dust collector 5 moves back and forth together with the inlet body 3 and the like following the pushing and pulling operation of the grip 2 and the like.
On the other hand, when the direction of travel of the suction port body 3 is changed by the operation using the grip portion 2 or when the suction port body 3 is inserted into a narrow gap, the user can change the direction of the suction port body 3 through the rigid body 6 connected to the grip portion 2 by, for example, twisting the hand H gripping the grip portion 2 around the axis a as shown in fig. 4.
At this time, according to the first embodiment, since the weight of the electric blower 13, the power supply unit 15, the dust collecting device 5, and the like is arranged so as not to follow the twisting motion of the grip portion 2, even if the grip portion 2 is twisted, the electric blower 13, the power supply unit 15, the dust collecting device 5, and the like are held in position, and the moment generated by these weight is small with respect to the twisting operation of the grip portion 2. Therefore, although the weight of the electric vacuum cleaner 1 held by the user does not change, the user does not need to apply a force to the hand H to move or stop the heavy object, and the load on the hand H of the user holding the grip portion 2, particularly on the wrist, can be reduced.
Further, as shown in fig. 3, by providing the inlet 21 of the dust collection device 5 at a position along the air passage between the suction port body 3 and the grip 2, the dust collection device 5 can be arranged without greatly protruding from the rigid body 6, unlike the configuration in which the air passage is bent by a hose or the like and guided to the dust collection device 5, and the electric vacuum cleaner 1 can be configured compactly.
Therefore, even when the user gripping the grip portion 2 performs an operation other than the twisting operation, the electric vacuum cleaner 1 is less likely to swing due to the heavy object, and the load applied to the hand H of the user gripping the grip portion 2 during the operation can be reduced.
When the above twisting operation of the grip portion 2 is performed, the sliding portion 30 and the insertion portion 38 slide, and the heavy objects such as the electric blower 13, the power supply portion 15, and the dust collector 5 do not follow the twisting operation of the grip portion 2. Further, since the slide portion 30 is disposed in the air passage that communicates the suction port body 3 and the dust collecting device 5 and the insertion portion 38 is disposed along the axis a of the extension pipe 27, each portion of the electric vacuum cleaner 1 can be disposed compactly around the rigid body 6.
In the present embodiment, since the sliding portion 30 and the insertion portion 38 are provided along the extension pipe 27 which is a part of the rigid body 6, the sliding portion 30 and the insertion portion 38 can be easily slid with respect to the twisting operation of the grip portion 2, and the weights such as the electric blower 13, the power supply portion 15, and the dust collector 5 can be easily made to be non-follow with respect to the twisting operation of the grip portion 2.
Further, since the grip portion 2 is connected to the rigid body 6 by the connecting portion 36 coaxial with the extension pipe 27, the twisting motion of the grip portion 2 is easily transmitted to the suction port body 3, and the operability is good.
Further, since the electric blower 13, the power supply unit 15, the dust collecting device 5, and other heavy objects are disposed in the vicinity of the grip portion 2, the weight of the electric vacuum cleaner 1 is concentrated in the vicinity of the grip portion 2. Therefore, the handling of the electric vacuum cleaner 1 when the electric vacuum cleaner 1 is operated while gripping the grip portion 2 is good and the operability is excellent, compared to the case where the weight of the electric vacuum cleaner 1 is dispersed at a position distant from the grip portion 2.
(second embodiment)
Next, a second embodiment will be described with reference to fig. 5 to 7. The same components and functions as those of the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
In the electric vacuum cleaner 1 of the present embodiment, the dust collecting device 5 is coaxially connected to the extension pipe 27, and the dust collecting device 5 is connected to the grip 2. That is, in the present embodiment, the grip portion 2 and the suction port body 3 are connected by the extension pipe 27 and the dust collecting device 5, and these extension pipe 27 and dust collecting device 5 correspond to a "rigid body".
One end of the grip portion 2 is integrally fixed to the connection receiving portion 19 of the box portion 4, and the other end extends in a free end shape.
Further, the cover member 41 surrounds the dust collection device 5 and is integrally formed with the case portion 4, and the dust collection device 5 is displaced inside the cover member 41. As shown in fig. 7A to 7C, the width W1 of the discharge port 22 of the dust collection device 5 is wider than the width W2 of the inlet 42 of the air passage to the first body 17 of the box 4, and even in a state where the positions of the dust collection device 5 and the first body 17 are relatively displaced (in a state of being displaced to the left and right in fig. 7A to 7C) in association with the twisting operation of the grip 2, the connection of the air passage on the suction side of the electric blower 13 in the first body 17 of the box 4 to the dust collection device 5 can be maintained by maintaining the communication between the discharge port 22 and the inlet 42. The discharge port 22 and the inlet port 42 are sealed by a sealing member so as to be slidable with respect to each other.
The first body 17 and the second body 18 are configured not to follow a predetermined movement of the grip portion 2. That is, the case portion 4 includes the sliding portion 30 at the connection portion connecting the receiving portion 19 and the first body portion 17. Therefore, the weight such as the electric blower 13 and the power supply unit 15 accommodated in the first body 17 and/or the second body 18 of the box portion 4 is not following the predetermined operation of the grip portion 2, i.e., the twisting operation in the present embodiment.
The connection part between the extension pipe 27 and the dust collecting device 5 serves as an inlet 21 for dust-containing air. The inlet 21 is disposed between the suction port body 3 and the grip 2. In the present embodiment, the inlet 21 is disposed at an end of the dust collecting device 5 in the longitudinal direction. In the illustrated example, the inlet 21 is disposed at one end of the dust collecting device 5, i.e., at the front end. The introduction port 21 of the present embodiment is located on the axis a of the extension pipe 27.
By disposing the weight so as not to follow the twisting motion of the grip 2 and providing the inlet 21 of the dust collector 5 at a position along the air passage between the suction port body 3 and the grip 2 in this way, as in the first embodiment, even if the grip 2 is twisted, the electric blower 13, the power supply unit 15, the dust collector 5, and the like are held at the positions, and the moment generated by the weight is not generated with respect to the twisting operation of the grip 2, and the load on the hand H of the user gripping the grip 2, particularly the wrist, can be reduced. Further, since the dust collection device 5 can be disposed so as not to largely protrude from the rigid body 6, and the electric vacuum cleaner 1 can be configured compactly, the load applied to the hand H of the user gripping the grip portion 2 during operation can be reduced.
Further, by arranging the extension pipe 27, the dust collecting device 5, and the grip portion 2 on the axis a and connecting the grip portion 2 to the connection receiving portion 19 of the box portion 4, a space for accommodating the electric blower 13, the control portion 14, and the power supply portion 15 can be obtained largely inside the box portion 4 without providing the insertion portion 38 and the like in the box portion 4, and the box portion 4 can be downsized. Further, since the electric blower 13, the control unit 14, and the power supply unit 15 housed in the box portion 4 can be disposed close to the axis a of the extension pipe 27, the electric vacuum cleaner 1 can be configured to be small and light, and the load applied to the hand of the user when performing a pushing and pulling operation other than the twisting operation of the grip portion 2 can be reduced.
In each of the above embodiments, the rigid body 6 is not limited to the configuration including the pipe body or the configuration including the dust collecting device 5, and the suction port body 3 and the grip portion 2 may be connected by any other rigid structure.
The weight that is not to follow the predetermined movement of the grip portion 2 is not limited to the dust collecting device 5, the electric blower 13, the power supply portion 15, and the like, and may be arranged so that the predetermined movement of any other weight with respect to the grip portion 2 is not to follow.
Several embodiments of the present invention have been described, but these embodiments are provided as examples and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various ways, and various omissions, substitutions, and changes can be made without departing from the spirit of the invention. These embodiments and modifications thereof are included in the scope and gist of the invention, and are included in the invention described in the claims and the equivalent scope thereof.
