Disclosure of Invention

However, the electric vacuum cleaner of patent document 1 is configured such that the battery storage box is attached to the cleaner body, and the electric blower as a heavy object is located at a short distance from the battery storage box. In the case of the above-described configuration of the electric vacuum cleaner, there is a problem in that: when the posture of the cleaner is to be changed, for example, to a posture in which the suction port is directed upward for cleaning a high place, the user must forcibly turn the wrist or the like, and an operation for placing a burden on the user is required.

Accordingly, an object of the present invention is to provide an electric vacuum cleaner which is easy to perform an operation for changing the posture and has excellent operability.

In order to solve the above problems, an electric vacuum cleaner according to an embodiment of the present invention includes: a cleaner body having an electric blower, a suction port provided at one side of the cleaner body, a grip portion extending from the cleaner body to the other side, and a battery portion having a battery; the battery unit is provided at a position of the grip unit away from the cleaner body.

The electric vacuum cleaner of the invention is provided with a battery at a position far away from the electric vacuum cleaner main body in a holding part. Therefore, the electric vacuum cleaner of the present invention includes the cleaner body on one side and the battery on the other side with the grip portion as a reference. In the electric vacuum cleaner of the present invention, the vacuum cleaner main body has the electric blower, and the battery unit has the battery, and therefore, the electric vacuum cleaner main body has a certain weight. Therefore, the electric vacuum cleaner of the present invention can change the posture with a light force by using the weight of the battery as long as the force is applied to the suction port in a state of holding the holding portion so as to face upward. In contrast, in the electric vacuum cleaner of the present invention, the posture can be changed with a light force by the weight of the electric blower as long as the force is applied so that the suction port faces downward while the grip portion is gripped. Thus, according to the present invention, it is possible to provide an electric vacuum cleaner which is easy to perform an operation for changing the posture and has excellent operability.

Detailed Description

Hereinafter, the electric vacuum cleaner 1 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, the overall configuration of the electric vacuum cleaner 1 will be briefly described, and then the main portions will be described in detail. In the following description, unless otherwise specified, positional relationships in the vertical direction, the width direction, and the like will be described with reference to a state in which the electric vacuum cleaner 1 is erected as shown in fig. 1.

"integral constitution of electric vacuum cleaner 1

As shown in fig. 1, the electric vacuum cleaner 1 is a vacuum cleaner having a stick-like (upright) appearance. The electric vacuum cleaner 1 is a charging type vacuum cleaner. As shown in fig. 1, the electric vacuum cleaner 1 includes a cleaner body 10, a pipe portion 30, a suction tool 40, a grip portion 50, and a battery portion 70.

The cleaner body 10 is a part constituting the electric cleaner 1 and functions to generate suction force and collect dust. As will be described in detail later, the cleaner body 10 includes a body casing 12 constituting a housing, and the interior of the body casing 12 is provided with an electric blower 14 for drawing air and generating an air flow and a dust collection unit 16. The cleaner body 10 has a suction port 18 on the front end side of the main body casing 12.

The electric blower 14 is constituted by, for example, a fan motor in which a motor and a fan are integrated. The electric blower 14 may drive a fan by energizing a motor, thereby generating an air flow. The electric blower 14 is arranged to generate an airflow in a direction from the suction port 18 toward the inside of the main body casing 12.

The dust collection unit 16 is provided at a position on the side of the suction port 18 with respect to the electric blower 14. Therefore, the dust sucked by operating the electric blower 14 can be collected in the dust collection unit 16 through the suction port 18. The dust collecting unit 16 may be a so-called cyclone type dust collecting device having a hollow space into which dust can flow, or a container or paper bag for collecting dust so as to be inserted and removed.

The suction port 18 is an opening portion provided on an end portion of the main body casing 12. The suction port 18 is used to suck dust sucked by operating the electric blower 14 into the main body casing 12. The suction port 18 is formed to be able to appropriately attach and detach the tube portion 30. Therefore, the electric vacuum cleaner 1 can be used in a form in which dust is directly sucked through the suction port 18, or in a form in which dust is sucked through the pipe portion 30 and the suction port 18 in a state in which the pipe portion 30 is inserted into the suction port 18.

The pipe portion 30 is a tubular member that detachably connects the cleaner body 10 and the suction tool 40. One end of the tube 30 is configured to be connectable to the suction port 18, and the other end is configured to be connectable to the suction tool 40. By connecting the cleaner body 10 and the suction piece 40 via the pipe portion 30, a series of communicating passages from the suction piece 40 to the cleaner body 10 can be formed. As shown in fig. 9, the fitting-type gap nozzle 32 can be attached to and detached from the pipe portion 30. Specifically, a substantially rectangular nozzle holding portion 36 is connected to a tubular tube holding portion 34 that is removably fitted over the tube portion 30, and the gap nozzle 32 is removably inserted into the nozzle holding portion 36. Further, the tube holding portion 34 has a slit 34a along the cylinder axis at a portion projecting toward the nozzle holding portion 36 side, so that the tube holding portion 34 has a repulsive force.

The suction tool 40 includes a suction tool main body 42 and a joint 44. The suction tool main body 42 is a portion disposed on the floor during cleaning, and has a shape elongated in the left-right direction with respect to the front-rear direction, which is the direction of movement of the user during cleaning. The suction tool main body 42 has an opening end on the floor surface side formed therein, and a suction space for sucking air or dust from the outside is formed therein. The joint 44 is attached to the suction tool main body 42 so as to be rotatable within a predetermined rotation range (the front-rear direction and the left-right direction). The joint portion 44 is a portion connected to an end of the pipe portion 30. The joint portion 44 has a cylindrical shape, and the internal space communicates with the suction space. The joint portion 44 may be configured by a first pipe that rotates in the left-right direction and a second pipe that is connected to the first pipe and rotates in the front-rear direction with respect to the first pipe, or may be configured by a universal joint having a spherical shape. As shown in fig. 10, the suction tool body 42 is composed of an upper cover 46 and a lower cover 48, and the projection 44a provided on the joint portion 44 is fitted into a cutout portion 46a formed by cutting out the edge of the upper cover 46, thereby restricting the rotation of the joint portion 44 in the left-right direction.

The grip 50 is provided for a user of the electric vacuum cleaner 1 to grip the cleaner body 10. The grip portion 50 may be formed in an appropriate shape as long as it can be gripped by a user. For example, in the example shown in fig. 1, the grip portion 50 is configured such that the user can grip the cleaner body 10 by inserting fingers other than the thumb through an opening portion formed by combining the grip portion 50 with an insertion portion 60 described later.

The battery unit 70 is a part provided in the electric vacuum cleaner 1 to supply electric power. The battery unit 70 includes a battery 72 having a battery cell such as a lithium ion secondary battery, a nickel metal hydride secondary battery, or a lead storage battery. The battery unit 70 is electrically connected to the electric blower 14 so as to be able to supply electric power.

The electric vacuum cleaner 1 has substantially the above-described configuration. The electric vacuum cleaner 1 further includes a characteristic structure in each of the grip portion 50, the interposing portion 60, the battery portion 70, and the like. These characteristic configurations will be described in further detail below.

[ MEANS FOR solving PROBLEMS ] A grip section 50

As shown in fig. 1 to 3, the grip 50 has a shape extending toward the side opposite to the side (rear side) of the cleaner body 10 where the suction port 18 is provided. The grip 50 has one end on the side close to the electric blower 14 and the other end on the side away from the electric blower 14. The grip portion 50 is thick enough to be gripped by a hand.

The arrangement and shape of the grip portion 50 are determined in consideration of the relationship with the electric blower 14 and the battery portion 70. Specifically, as shown in fig. 2, when the centers of gravity of the electric blower 14 and the battery unit 70 are set to the centers of gravity G1 and G2, respectively, and a virtual line passing through the centers of gravity G1 and G2 is set to the first virtual line L1, a position that can be gripped by the grip unit 50 (a grippable position) is located on the second virtual line L2 that is orthogonal to the first virtual line L1 at the middle of the centers of gravity G1 and G2.

In the middle of the grip 50, i.e., in the middle of the centers of gravity G1, G2 of the electric blower 14 and the battery unit 70, there is a portion in which the weight balance is obtained according to the weight ratio of the weight on the electric blower 14 side to the weight on the battery unit 70 side. Therefore, if the grip 50 is disposed so that the grip position is located on the second virtual line L2 that is orthogonal to the first virtual line L1 between the centers of gravity G1 and G2 as described above, the operation of tilting the electric vacuum cleaner 1 so that the suction port 18 faces upward or tilting the electric vacuum cleaner 1 so that the suction port 13 faces downward (the storage is good) is facilitated in the state where the grip 50 is gripped.

That is, in the case where the grip portion 50 is disposed as described above, the posture of the electric vacuum cleaner 1 can be changed by applying only a light force to the extent that the weight balance is broken in a state where the middle of the grip portion 50 is gripped and the weight of the electric blower 14 side and the weight of the battery portion 70 side are balanced. Further, by gripping the position of the gripping portion 50 where the weight on the side away from the electric blower 14 and the weight on the side of the battery portion 70 are balanced, it is possible to grip the electric blower 14 in a state in which the side is inclined downward or grip the battery portion 70 in a state in which the side is inclined downward.

Further, the grip 50 is formed to extend in a direction parallel to the first virtual line L1 at a position distant from the first virtual line L1. Therefore, by adjusting the position for gripping the grip portion 50 by moving the hand along the grip portion 50, it is possible to easily adjust the position at which the weight on the electric blower 14 side and the weight on the battery portion 70 side are balanced, or the position at which the weight balance is biased toward the electric blower 14 side or the battery portion 70 side. Therefore, the gripping position can be smoothly changed so that the position of the gripping portion 50 becomes an appropriate position according to the posture of the electric vacuum cleaner 1 desired by the user.

As shown in fig. 8, the grip 50 has a cover made of elastic resin and disposed on an upper surface of an inner periphery surrounding the opening 62. The grip 50 may have a protrusion 54 protruding toward the opening 62 at the middle in the longitudinal direction. The projecting portion 54 may be formed by molding the grip portion 50 itself to have the projecting portion 54, or by attaching another member constituting the projecting portion 54 to the grip portion 50. In the example shown in fig. 8, the projection 54 is made of a material such as an elastomer or a resin, and is configured as a part of a cover 56 attached to the grip 50. The protruding portion 54 can improve the comfort of the grip portion 50 by being provided in a size or a position suitable for placing fingers of a user gripping the grip portion 50. Further, the projecting portion 54 is provided at a position (balance position) where the weight of the electric blower 14 and the weight of the battery unit 70 are balanced, so that the user can be guided to the grip position to grip the grip portion 50 at the balance position. This makes it possible to hold the grip portion 50 at a position suitable for operation, even if the user does not intend to do so.

Section 60 of introduction

As shown in fig. 2 to 4, the intervening portion 60 is a portion that is formed separately from the grip portion 50 and extends from an end of the cleaner body 10. The insertion portion 60 is a portion that is interposed between the battery portion 70 provided in the grip portion 50 and the cleaner body 10 as described later. The insertion portion 60 is formed such that at least a part (all in the present embodiment) thereof constitutes the cleaner body 10.

The insertion portion 60 is shaped to extend toward the opposite side (rear side) of the cleaner body 10 from the side where the suction port 18 is provided, similarly to the grip portion 50. The thickness of the intermediate portion 60 is the same as that of the holding portion 50. The intervening portion 60 is located on the opposite side (rear side) from the grip portion 50 located on the front side of the electric vacuum cleaner 1 with respect to the axial position of the electric vacuum cleaner 1. The intermediate portion 60 is formed to extend substantially parallel to the grip portion 50. The intermediate portion 60 is combined with the grip portion 50, and is connected in a ring shape in a state where the electric vacuum cleaner 1 is viewed from the side, thereby forming an opening portion 62 into which fingers can be inserted.

Since the electric vacuum cleaner 1 is provided with the insertion portion 60 as described above, it is possible to relieve the stress applied to the grip portion 50 or the battery portion 70 by the attachment/detachment operation of the battery 72 in the battery portion 70, the user gripping the grip portion 50 to perform cleaning, or the like, toward the cleaner body 10. Further, since the grip portion 50 and the intermediate portion 60 are formed in a ring shape, it is possible to suppress stress generated by manipulation of the grip portion 50 and the like from concentrating at one position, and to suppress local generation of excessive force.

About Battery section 70

As shown in fig. 1 to 4, the battery unit 70 is provided at a position apart from the cleaner body 10 in the grip unit 50. The battery unit 70 is provided at a position opposite to (on the other end side of) one end side of the grip 50 connected to the cleaner body 10. The battery unit 70 includes a battery 72, a battery case 74, and a slide structure 76 (see fig. 4 and the like).

As shown in fig. 5, the battery 72 houses a battery unit such as a lithium ion secondary battery, a nickel metal hydride secondary battery, or a lead storage battery inside a case 78. The battery 72 may be a dedicated product of the electric vacuum cleaner 1, but may be shared with other devices such as an electric power tool. The battery 72 is exposed so as to be grippable in a state of being attached to a battery case 74 fixed to the grip portion 50 side.

The housing 78 has a substantially rectangular parallelepiped external shape. Housing 78 has a front surface 78a, a rear surface 78b, sides 78c, 78d, a surface 78e, and a back surface 78 f. As shown in fig. 4, the front surface 78a is a surface facing the cleaner body 10 with the battery 72 attached to the battery case 74. The rear surface 78b is a surface located on the opposite side of the front surface 78 a. The side surfaces 78c, 78d are surfaces connecting the front surface and the rear surface 78b at the sides of the housing 78. The surface 78e faces the battery case 74 side in a state where the battery 72 is mounted in the battery case 74. The back surface 78f is the surface opposite the surface 78 e. The case 78 is hollow, and the battery unit is housed therein. The housing 78 is sized to be held by a user with one hand. Specifically, the housing 78 is sized to be gripped with the thumb placed on one side of the side surfaces 78c and 78d and the other finger or fingers placed on the other side.

As shown in fig. 5, the battery 72 includes an operation portion 80 and an engagement portion 82. The operation portion 80 is a portion for performing an engagement releasing operation for releasing the engagement between the battery 72 and the battery case 74. The operation portion 80 may have any suitable configuration as long as it can perform the engagement releasing operation. In the present embodiment, the operation portion 80 includes a pressing portion 84.

The pressing portion 84 is provided at a position on the front surface 78a side in the case 78 of the battery 72. Thus, the pressing portion 84 is provided at the front side in the detaching direction when the battery 72 is detached from the battery case 74. The pressing portion 84 is disposed at a position that can be reached by the index finger or the middle finger of the hand to be held, for example, in a state where the thumb is placed on one side of the side surfaces 78c and 78d of the case 78 and the other finger or fingers is placed on the other side to hold the case 78. Therefore, the battery 72 can operate the pressing portion 84 while holding the case 78 with one hand.

The pressing portion 84 is urged from the rear surface 78b side toward the front surface 78a side by an urging member such as a spring provided inside the housing 78. The pressing portion 84 can be pressed from the front surface 78a side toward the rear surface 78b side against the urging force of the urging member to operate. The pressing portion 84 can be returned to the original position by the urging force of the urging member by releasing the pressing force.

The engaging portion 82 engages with an engaged portion 88 provided on the battery case 74 side, which will be described later. The engaging portion 82 engages and fixes the battery 72 in the battery case 74 by being combined with the engaged portion 88. The engaging portion 82 is provided to project toward the outside of the housing 78 on the surface 78e side of the housing 78. The engaging portion 82 and the pressing portion 84 are connected to each other via an operating mechanism (not shown) provided inside the housing 78 so as to be capable of transmitting power. Thus, the engaging portion 82 can be operated (slid in the present embodiment) on the surface 78e side of the housing 78 in conjunction with the pressing operation of the pressing portion 84.

The battery case 74 is a case that can be engaged with and disengaged from the battery 72. The battery case 74 is inclined at an acute angle with respect to the axial direction of the electric vacuum cleaner 1. Battery case 74 has an insertion portion 86 recessed in a shape capable of being inserted into the surface 78 e-side portion of battery 72. As shown in fig. 6, the insertion portion 86 has an open portion 86a that is open at a portion on the front surface 78a side of the case 78 in a state in which the battery 72 is inserted. The insertion portion 86 has an insertion bottom surface 86b adjacent to the surface 78e of the case 78 in a state where the battery 72 is mounted. In the insertion portion 86, side walls 86c and 86d are provided so as to stand adjacent to the side surfaces 78c and 78d in a state where the battery 72 is inserted.

The battery case 74 has an engaged portion 88 that can be engaged with the engaging portion 82 of the battery 72. The engaged portion 88 is recessed so as to be engageable with the engaging portion 82 at a position where the engaging portion 82 of the battery 72 is located in a state where the battery 72 is fitted into the fitting portion 86.

The slide structure 76 is a structural part for enabling an operation (sliding operation) of sliding the battery 72 with respect to the battery case 74 when the battery 72 is attached to and detached from the battery case 74. Slide structure 76 may be any structure as long as it allows battery 72 to slide relative to battery case 74, and may have any suitable structure, and in the present embodiment, is formed by a combination of convex portion 90 (see fig. 6) and groove portion 92 (see fig. 5). Convex portion 90 and groove portion 92 may be provided on either one or both of battery 72 and battery case 74. In the present embodiment, convex portion 90 is provided on the battery case 74 side, and groove portion 92 is provided on the battery 72 side. Specifically, the battery 72 has groove portions 92, 92 formed in a shape recessed to the side of the case 78 on the side surfaces 78c, 78d of the case 78. In addition, protruding portions 90, 90 are provided in insertion portion 86 of battery case 74.

The protruding portions 90, 90 protrude from the side walls 86c, 86d on both sides in the width direction of the fitting portion 86 toward the inside of the fitting portion 86, respectively. The projections 90, 90 are formed in a flange shape. Convex portions 90 and 90 are formed substantially parallel to fitting bottom surface 86b at a predetermined interval.

Groove 92 is provided at a position where projections 90, 90 on the battery case 74 side can enter when battery 72 is inserted from opening 86a of insertion portion 86 with surface 78e of case 78 facing insertion bottom surface 86b of insertion portion 86. The grooves 92, 92 extend substantially linearly from the opening portion 86a of the fitting portion 86 to the engaged portion 88 side. Therefore, when the battery 72 is inserted into the opening portion 86a of the insertion portion 86 or the battery 72 is pulled out from the insertion portion 86, the case 78 of the battery 72 is guided by the convex portions 90, 90 and the groove portions 92, 92.

The battery unit 70 can be disengaged from the battery case 74 by performing a sliding operation of sliding the battery 72 toward the front side (the cleaner body 10 side) in a state where the engagement between the engaging portion 82 and the engaged portion 88 is released (an engagement released state). In contrast, when the battery 72 is attached to the battery case 74, the battery 72 attached to the fitting portion 86 is slid toward the rear side (the side opposite to the cleaner body 10) with respect to the battery case 74 along the inclination of the fitting bottom surface 86 b. When the battery 72 is slid relative to the battery case 74 until the engaging portion 82 provided on the battery 72 side reaches the engaged portion 88 provided on the battery case 74 side, the engaging portion 82 and the engaged portion 88 are engaged with each other. Thereby, the battery 72 is fixed to the battery case 74.

Since the battery unit 70 has the above-described configuration, the battery 72 can be easily attached and detached. Specifically, when the battery 72 is taken out from the battery case 74, for example, the thumb is placed on one side surface 78c of the case 78 of the battery 72, and the other one or more fingers (little finger, ring finger, or the like) are placed on the other side surface 78d to hold the case 78, and the index finger or middle finger of the holding hand is placed on the pressing portion 84 as the operation portion 80. In this state, the pressing portion 84 is pressed toward the rear end side (the side opposite to the suction port 18) of the electric vacuum cleaner 1, and the hand holding the battery 72 is slid toward the front end side (the suction port 18 side) of the electric vacuum cleaner 1 as indicated by an arrow a in fig. 3. Thereby, the battery 72 slides toward the front end side of the electric vacuum cleaner 1 with respect to the battery case 74 under the guide of the slide structure 76, and finally comes to a state of being detached from the battery case 74.

On the other hand, when the battery 72 is mounted, the thumb is placed on, for example, one side surface 78c of the case 78 of the battery 72, and the case 78 is gripped with one or more fingers (a little finger, a ring finger, or the like) placed on the other side surface 78 d. In this state, as shown by an arrow B in fig. 3, the battery 72 is slid with respect to the insertion portion 86 provided on the battery case 74 to enter from the open portion 86 a. Battery 72 slides under the guidance of convex portions 90, 90 and groove portions 92, 92 constituting slide structure 76. When the battery 72 is slid until the engaging portion 82 reaches the position of the engaged portion 88, the engaging portion 82 and the engaged portion 88 are engaged, and the battery 72 is fixed to the battery case 74.

In the battery unit 70, when the battery 72 is attached and detached, the battery 72 slides along the inclination of the battery case 74. The battery case 74 is inclined at an acute angle with respect to the axis of the electric cleaner 1. Therefore, when the battery 72 is attached and detached, the battery 72 or the hand of the user can be prevented from interfering with other components such as the cleaner body 10.

Modifications of the examples

The electric vacuum cleaner 1 described above is merely one embodiment of the present invention, and other embodiments can be made according to the teaching and spirit thereof without departing from the scope of the claims. A modified example of the electric vacuum cleaner 1 will be described below.

The electric vacuum cleaner 1 described above includes the intervening portion, but the present invention is not limited to this, and a configuration may be adopted in which the intervening portion 60 is not provided. In the above-described embodiment, the interface 60 is formed by the housing constituting the cleaner body 10, but the present invention is not limited thereto. For example, the interface 60 may be a housing at least partially constituting the cleaner body 10. Specifically, a portion constituted by a housing constituting the cleaner body 10 may be connected to another member provided separately to function as the interface portion 60. The entire interface 60 may be formed of a separate member from the cleaner body 10.

Further, although the above-described configuration in which the electric vacuum cleaner 1 has the operation portion 80 for performing the engagement releasing operation for releasing the engagement between the battery 72 and the battery case 74 provided on the distal end side in the disengaging direction of the battery 72 (the distal end side of the electric vacuum cleaner 1) has been illustrated, the present invention is not limited thereto. For example, as shown in fig. 7 (a), the electric vacuum cleaner 1 may be configured such that the operation unit 80 is provided on the rear end side in the detaching direction of the battery 72 (the rear end side of the electric vacuum cleaner 1).

The electric vacuum cleaner 1 described above is capable of taking out the battery 72 by sliding the battery 72 relative to the battery case 74 toward the cleaner body 10 (the front end side of the electric vacuum cleaner 1), but the present invention is not limited to this. For example, as shown by an arrow C, D in fig. 7 (a) and (b), the battery 72 may be removed by sliding the battery 72 relative to the battery case 74 in a direction away from the cleaner body 10 (toward the rear end of the electric vacuum cleaner 1).

In the electric vacuum cleaner 1, the battery unit 70 is disposed on the rear surface side, but the present invention is not limited thereto. For example, as shown in fig. 7 (b) and (c), the battery unit 70 may be disposed on the front surface side of the vacuum cleaner 1. Even when the battery unit 70 is disposed on the front surface side, the direction in which the battery 72 is taken out can be appropriately changed. That is, as shown by an arrow D in fig. 7 b, the battery 72 may be removed by sliding the battery 72 on the front side of the electric vacuum cleaner 1 relative to the battery case 74 in a direction away from the cleaner body 10 (rear end side of the electric vacuum cleaner 1). As shown by an arrow E in fig. 7 c, the battery 72 may be removed by sliding the battery 72 on the front side of the electric vacuum cleaner 1 relative to the battery case 74 in a direction toward the cleaner body 10 (toward the front end of the electric vacuum cleaner 1).

The electric vacuum cleaner 1 described above has an acute angle formed between the direction of disengagement when the battery 72 is disengaged from the battery case 74 and the axial direction of the cleaner body 10, but the present invention is not limited to this. That is, the electric vacuum cleaner 1 may be formed such that the detaching direction when the battery 72 is detached from the battery case 74 is substantially parallel to the axial direction of the cleaner body 10, or the like.

The electric vacuum cleaner 1 is provided with the slide structure 76 for performing the operation of sliding the battery 72 with respect to the battery case 74, but the present invention is not limited thereto. For example, the electric vacuum cleaner 1 may not include the sliding structure 76, or the sliding structure 76 may have a different configuration from the above-described one. Specifically, although the sliding structure 76 is configured such that the groove portion 92 is provided on the battery 72 side and the protrusion portion 90 is provided on the battery case 74 side, for example, a configuration in which the protrusion portion 90 is provided on the battery 72 side and the groove portion 92 is provided on the battery case 74 side may be employed. The sliding structure 76 may be formed of a combination other than the combination of the convex portion 90 and the groove portion 92.

The battery 72 of the electric vacuum cleaner 1 is exposed for gripping, but the present invention is not limited thereto. For example, the electric vacuum cleaner 1 may be configured such that the battery 72 is entirely housed in the battery case 74. Further, although the above-described electric vacuum cleaner 1 has been described as having the operation portion 80 disposed at a position where the fingers gripping the battery 72 are placed, the present invention is not limited to this, and the operation portion 80 may be provided at another portion of the battery 72.

The electric vacuum cleaner 1 may be configured such that the operating portion 80 and the engaging portion 82 interlocking with the operating portion are not provided on the battery 72, but are provided on the battery case 74, and the engaged portion 88 is provided on the battery 72 side. Even in the case of this configuration, the battery 72 can be easily attached and detached as described above.

The electric vacuum cleaner 1 described above has the following configuration as means for solving various problems in the related art.

(1-1) the electric vacuum cleaner 1 is characterized by comprising: a cleaner body 10 having an electric blower 14, a suction port 18 provided at one side of the cleaner body 10, a grip 50 extending from the cleaner body 10 to the other side, and a battery unit 70 having a battery 72; the battery unit 70 is provided at a position of the grip 50 apart from the cleaner body 10.

The electric vacuum cleaner 1 is provided with a battery unit 70 at a position of the grip 50 distant from the cleaner body 10. Therefore, the electric vacuum cleaner 1 includes the cleaner body 10 on one side and the battery unit 70 on the other side with reference to the grip unit 50. In the electric vacuum cleaner 1, since the cleaner body 10 includes the electric blower 14 and the battery unit 70 includes the battery 72, each of them has a certain weight. Therefore, the electric vacuum cleaner 1 can change the posture to the suction port 18 upward by the weight of the battery unit 70 by applying a slight upward force in a state where the grip unit 50 is gripped. On the contrary, the electric vacuum cleaner 1 can change the posture to the suction port 18 downward by the weight of the electric blower 14 by applying a slight downward force in a state where the grip portion 50 is gripped. Thus, according to the electric vacuum cleaner 1, the operability of the operation (the retracting operation) for changing the posture can be improved.

(1-2) the electric vacuum cleaner 1 is characterized by comprising an intervening part 60 interposed between the battery part 70 and the cleaner body 10.

According to the above configuration, stability and strength of the grip portion 50 and the battery portion 70 to which stress is applied during use can be improved.

(1-3) the electric vacuum cleaner 1 is characterized in that the grip 50 is formed to: when the centers of gravity G1, G2 of the electric blower 14 and the battery 72 are set, and a first virtual line L1 passing through the centers of gravity G1, G2 is set, the grippable position is located on a second virtual line L2 orthogonal to the first virtual line L1 between the centers of gravity G1, G2.

According to the above configuration, operability of the retraction operation can be improved. Specifically, the electric vacuum cleaner 1 is provided with the grip portion 50 so that a portion having a weight balance between the weight of the electric blower 14 and the weight of the battery portion 70 is included between the centers of gravity G1 and G2. Therefore, in the state where the grip portion 50 is gripped, the operation (retracting operation) of tilting the electric vacuum cleaner 1 so that the suction port 18 faces upward or tilting the electric vacuum cleaner 1 so that the suction port 18 faces downward is facilitated.

(1-4) the electric vacuum cleaner 1 is characterized in that the grip 50 extends along a first virtual line L1 passing through the respective centers of gravity of the electric blower 14 and the battery 72.

According to the above configuration, the user can easily adjust the position of gripping the grip portion 50 by moving the hand along the grip portion 50, thereby making it possible to adjust the position where the weight on the side of gripping the electric blower 14 and the weight on the side of the battery portion 70 are balanced, or the position where the weight balance is biased toward the side of the electric blower 14 or the side of the battery portion 70. Therefore, the electric vacuum cleaner 1 can smoothly change the gripping position so that the gripping portion 50 is appropriately positioned according to the posture of the electric vacuum cleaner 1 desired by the user.

(1-5) the electric vacuum cleaner 1 is characterized in that the grip portion 50 has one end on the side close to the electric blower 14 and the other end on the side away from the electric blower 14, and the battery portion 70 is provided on the other end side of the grip portion 50.

According to the above configuration, the grip portion 50 can be gripped at an appropriate position where the weight is balanced between the electric blower 14 and the battery portion 70. Therefore, the electric vacuum cleaner 1 can be easily retracted and extended.

(1-6) the electric vacuum cleaner 1 is characterized by having an intervening portion 60 interposed between the battery portion 70 and the cleaner body 10, and at least a part of the intervening portion 60 is a housing constituting the cleaner body 10.

According to the above configuration, stress generated when the grip portion 50 is gripped or the battery 72 in the battery portion 70 is attached and detached can be dispersed to the cleaner body 10 side, and a load applied to the grip portion 50 or the battery portion 70 can be reduced.

Here, as in the electric vacuum cleaner of patent document 1, the electric vacuum cleaner of the related art is not easy to perform the work of attaching or detaching the battery storage box (battery) to or from the cleaner body. Specifically, in the electric vacuum cleaner of patent document 1, when removing the battery storage box, it is necessary to first slide the battery storage box downward away from the plate body to bend the plate body, and pull out the battery storage box rearward while maintaining the bent state of the plate body. In the vacuum cleaner of patent document 1, the battery storage box must be removed in reverse to the battery storage box. As described above, in the electric vacuum cleaner of the related art represented by the electric vacuum cleaner of patent document 1, a configuration is adopted in which the battery is difficult to attach and detach, and the operability is extremely poor. In order to solve the above problem, the electric vacuum cleaner 1 is configured as follows.

With the above configuration, the electric vacuum cleaner 1 can easily attach and detach the battery 72. Specifically, in the case of the above configuration, when removing the battery 72 from the battery case 74, the battery 72 can be removed by placing the fingers of the hand on the operation portion 80 while holding the battery 72 and sliding the battery 72 relative to the battery case 74. In addition, the battery 72 may be attached by reversing the operation of removing the battery. Therefore, the electric vacuum cleaner 1 described above facilitates the operation of attaching and detaching the battery 72.

(2-2) the electric vacuum cleaner 1 is characterized by comprising: the vacuum cleaner includes a cleaner body 10 having an electric blower 14, a suction port 18 provided on one side of the cleaner body 10, a grip 50 provided on the other side of the cleaner body 10, and a battery unit 70 having a battery 72 and a battery case 74 engageable with and disengageable from the battery 72, wherein the battery 72 can be disengaged from the battery case 74 by a sliding operation with respect to the battery case 74, and an angle formed by a disengagement direction of the battery 72 with respect to the battery case 74 and an axial direction of the cleaner body 10 is an acute angle.

According to the above configuration, when the battery 72 is attached and detached, interference between the battery 72, the user's hand, and other parts such as the cleaner body 10 can be suppressed.

(2-3) the electric vacuum cleaner 1 is characterized by comprising a sliding structure 76 for sliding the battery 72 with respect to the battery case 74, wherein the sliding structure 76 has a protrusion 90 provided on one or both of the battery case 74 and the battery 72, and a groove 92 provided on one or both of the battery case 74 and the battery 72 for slidably guiding the protrusion 90.

With the above configuration, the sliding operation of the battery 72 with respect to the battery case 74 can be smoothly and stably performed.

(2-4) the electric vacuum cleaner 1 is characterized in that the battery 72 is exposed so as to be able to be gripped, and an operation portion 80 is disposed at a placement position of fingers gripping the hand.

With the above configuration, the operator can hold the battery 72 with one hand and operate the operation unit 80. Therefore, according to the above configuration, the battery 72 can be easily attached and detached.
