In the present embodiment, the battery main body 27 is disposed inside the supported portion 16 of the case 15. The battery main bodies 27 of the present embodiment are arranged side by side in the width direction along the axial direction of the supported portion 16. The battery main bodies 27 are arranged in the width direction along the curved shape of the concave portion 17. Further, the secondary battery 26 is electrically connected to the wiring. The wiring is introduced into the cleaner body 2 and is connected to the electric blower 7 and the control unit.

  Next, a cleaning operation by the vacuum cleaner 1 according to one embodiment will be described.

  When cleaning the surface to be cleaned below the user, for example, the floor surface, the stick-type vacuum cleaner 1 is used in such a manner that the grip portion 12 is gripped and the suction port 3 is oriented downward to use the air path. The tip of the body 5 is turned to the surface to be cleaned. Next, the vacuum cleaner 1 is started by operating the setting means 13, and the negative pressure generated by driving the electric blower 7 is used while operating the gripping part 12 to move the suction opening body and the like along the surface to be cleaned. Then, the dust is sucked into the dust collecting portion 10 together with the air from the air path body 5 through the suction port 3. The dust collecting section 10 separates and collects dust from the dust-containing air. The air from which the dust is separated by the dust collecting unit 10 is discharged from the dust collecting unit 10 and is sucked into the electric blower 7. After the air blown into the electric blower 7 cools the electric blower 7, the air is exhausted from the exhaust port 4 to the outside of the cleaner body 2.

  When performing the cleaning in this manner, in the present embodiment, the case 15 having the secondary battery 26 serving as the power supply of the electric blower 7 is connected to the cleaner main body 2, and the case 15 is positioned upward with respect to the grip portion 12 gripped by the user. Position. For this reason, the electric blower 7 is located below the gripper 12 held by the user, and the secondary battery 26 is located above. Therefore, since the weight is distributed downward and upward with respect to the grip portion 12, the feeling of weight applied to the hand H of the user holding the grip portion 12 can be reduced.

  In addition, the supported portion 16 provided in the case 15 is supported by the hand H of the user holding the holding portion 12, so that the weight of the secondary battery 26 provided in the case 15 can be reduced by the user holding the holding portion 12. Can be supported by the hand H, and the feeling of weight applied to the hand H of the user holding the holding portion 12 can be reduced.

  In particular, in the case of the vacuum cleaner 1 in which the gripper 12 is bent in the vertical direction, the user normally applies a load of a heavy object in the direction in which the finger of the hand H gripping the gripper 12 is always opened. Most of the load of the vacuum cleaner 1 is applied to the finger of the hand H, and it is necessary to squeeze the grip portion 12 with force in the direction of closing the finger of the hand H. According to the present embodiment, the case 15 having the heavy secondary battery 26 is placed on the hand H, so that the weight of the secondary battery 26 does not catch on the finger of the hand H, and is placed on the hand H. In other words, since the load of the secondary battery 26 is received by the back of the hand H, the force put into the finger can be suppressed, and the feeling of weight can be effectively suppressed.

  As a result, even if the vacuum cleaner 1 is used for a long time, the user's fatigue caused by the load of the heavy weight of the vacuum cleaner 1 can be suppressed.

  Since the concave portion 17 is formed at a position of the supported portion 16 facing the grip portion 12, the concave portion 17 follows the shape of the hand H of the user holding the grip portion 12, and the supported portion 16 of the case 15 is held by the hand H. Can be stably supported. In the case of a secondary battery 26 composed of a plurality of battery bodies 27, the battery body 27 can be easily arranged in the supported portion 16 of the case 15 along the recess 17, so that the recess 17 adapted to the shape of the hand H can be easily formed. it can.

  The case 15 is movably supported by the cleaner main body 2 in a direction in which the case 15 approaches and separates from the grip portion 12, so that the case 15 is separated from the grip portion 12 when gripping the grip portion 12. As the position, the user can easily grip the grip portion 12, and in a state where the grip portion 12 is gripped, the supported portion 16 of the case 15 can be easily moved by the user's hand H as the position where the case 15 is brought close to the grip portion 12. Can be supported. Further, since the size and thickness of the user's hand H holding the holding unit 12 vary depending on the user, the case 15 is movably moved to the cleaner body 2 in a direction approaching to and away from the holding unit 12. By supporting, the gap between the gripper 12 and the case 15 can be changed to correspond to the size and thickness of the hand H of the user holding the gripper 12.

  At this time, by urging the case 15 toward the grip portion 12 by the urging means 22, the state in which the case 15 is pressed against the user's hand H holding the grip portion 12 can be maintained. Therefore, for example, even when the user twists the hand H holding the holding unit 12, the case 15 can be hard to separate from the hand H. Therefore, the user's hand H is pressed against the gripper 12 via the case 15 by the urging force of the urging means 22, so that the gripper 12 is pushed and pulled by the palm without gripping the gripper 12. Then, the vacuum cleaner 1 can be operated.

  In addition, by arranging the soft member 24 on the side of the case 15 facing the grip portion 12, the contact of the case 15 with the hand H supporting the supported portion 16 can be eased by the soft member 24, and the case 15 has been used for a long time. However, the vacuum cleaner 1 with a small load on the hand H can be provided.

  In the above-described embodiment, the driving unit is the electric blower 7. However, the present invention is not limited to this. The driving unit may be driven by the secondary battery 26 as a power source and may be any driving unit having a large weight. Can be.

  Although several embodiments of the present invention have been described, these embodiments are provided by way of example and are not intended to limit the scope of the invention. These new embodiments can be implemented in other various forms, and various omissions, replacements, and changes can be made without departing from the spirit of the invention.
