Next, the operation of this embodiment will be explained.

When cleaning, for example, the user holds the handle 16 and moves the suction port 63 to face the surface to be cleaned. When the electric blower 23 is driven, the dust sucked in from the suction port 63 is filtered through the filter material 7.
3, the airflow is collected in the dust collection filter 71, and the airflow that has passed through the filter material 73 passes through the urethane resin filter 52 and the communication port 21,
It is discharged from the exhaust port 29.

When storing the vacuum cleaner main body 11 in the storage case 81 after cleaning, etc., the storage case 8
The vacuum cleaner main body 11 is placed on the top surface of the vacuum cleaner 1. At this time,
Due to the load of the vacuum cleaner body 11, the storage clamp 8
7 rotates and is engaged with the suction port 63 which is the locked part of the vacuum cleaner main body 11, and the battery cover 33
and the joined protrusion 39 of the vacuum cleaner body 11,
Since the lower surface of the storage case 81 is inclined, the storage case 81 is elastically deformed, and the projection 41 and the knob projection 39, which are the locked parts, are engaged with the locking hole 94 thereof. Then, the engagement stepped portion 1 on the side of the vacuum cleaner body 11
8, 34, and 69 are brought into contact with the opening edge 82 of the storage case 81, and the cleaner body 11 is securely locked to the storage case 81.

In this state, as shown in FIG. 1, the center of gravity of the heavy battery 32 located below the handle 16 in the vacuum cleaner main body 11 is approximately at the same height as the top surface of the storage case 81, and the lower part of the battery 32 is placed in the storage case 81. case 8
Located within 1. In addition, the relatively heavy electric blower 2
3 is located in the center of the vacuum cleaner main body 11, the support state of the storage case 81 to the mounting surface 100 and the support state of the vacuum cleaner main body 11 to the storage case 81 are stable, and it is difficult to fall over. Even if you fall, the impact will be small.

Further, when the vacuum cleaner body 11 is attached to the storage case 81, the suction port 63 is located inside the storage case 81. However, in this state, even if the switch 26 is operated by mistake and the electric blower 23 is driven, the insertion hole 89 of the storage case 81
Since air flows in through the gaps 93 and 95 formed between the and locking holes 94, the electric blower 23 is normally cooled and does not overheat, and failure can be reliably prevented.

Furthermore, the cleaner main body 11 can be carried by holding the handle 16 while attached to the storage case 81. At this time, the protrusion 41 of the cleaner body 11
is engaged with the locking hole 94, the lid body 33 will not open downward due to the load of the storage case 81, and there is no fear that the storage case 81 will fall off.

Furthermore, when the vacuum cleaner main body 11 is attached to the storage case 81, as shown in FIG. The protrusion 41 of the vacuum cleaner main body 11 and the knob protrusion 39 of the lid body 33, which form the support part, protrude rearward from the rear surface of the storage case 81, so in this state, cleaning is not carried out in order to save storage space. Machine body 11 and storage case 81
When placed upright with the rear side down, the legs 42,
Only the rear ends of the protrusion 41 and the knob protrusion 39 are brought into contact with the placement surface 100 as supporting portions, and the rear surface of the storage case 81 is positioned slightly off the placement surface 100. Therefore, since no force is directly applied to the storage case 81, the storage case 81 will not be deformed due to impact when placed, and the storage clamp 87 will not come off.

When the vacuum cleaner main body 11 is stood with its rear face down, even if the load of the battery 32 is applied to the battery cover 33 which is detachably attached to the vacuum cleaner main body 11, the cover 33 is held up by the protrusion 39. There is no bending and deformation, and the protrusions 41 of the vacuum cleaner main body 11 joined to both ends of the lid 33 also come into contact with the mounting surface 100, so the supporting state becomes more stable, and the lid 33 and the burden on the battery 32 is also reduced.

When removing the vacuum cleaner main body 11 from the storage case 81, push down the operating part 90 of the storage clamp 87, disengage the engaging part 91 of the storage clamp 87 from the suction port 63, and then move the front side of the vacuum cleaner main body 11. Remove the protrusion 41 and the knob protrusion 39 on the cleaner body 11 side from the locking hole 94 of the storage case 81 by lifting.

When replacing the deteriorated battery 32 with a new battery 32, the battery cover 33 is removed and the battery 32 is inserted and removed through the open opening 30, as shown in FIG. To remove the lid 33, put your fingers between the grip projection 39 and the projection 41 of the cleaner body 11, press the grip projection 39 downward, and slide the lid 33. At this time, the locking claw portion 35 of the lid body 33 comes off from the locking protrusion 37 of the cleaner body 11 due to its elasticity. And lid body 3
3, since an arc-shaped notch 40 is provided in the knob protrusion 39 of the lid body 33, it is natural to press the vicinity of this notch 40, and the protrusion of the vacuum cleaner body 11 may be accidentally removed. It is possible to prevent an erroneous operation in which the finger is placed on the portion 41 as well. Also, when reinstalling the lid 33, the lid 33 should be inserted into the engagement groove 38 of the vacuum cleaner main body 11.
3 is engaged from below, the lid body 33 is slid upward, and its locking claw portion 35 is engaged with the locking projection 37 of the cleaner body 11.

According to the above configuration, the knob protrusion 39 of the battery lid 33 is used both as a support part when the vacuum cleaner body 11 is placed upright and as a locked part when the vacuum cleaner body 11 is attached to the storage case 81. As a result, the structure is simple and the appearance is good. In addition, the vacuum cleaner body 11
The protrusion 41 has a structure that is continuous with both ends of the protrusion 39 of the lid body 33, so the structure does not become complicated due to the protrusion 41 provided on the vacuum cleaner body 11, and the appearance is improved. It doesn't get worse either.

(Effects of the Invention) According to the present invention, the opening/closing knob protrusion protrudes rearward from the left end to the right end on the rear surface of the lid that opens and closes the opening of the vacuum cleaner main body for storing batteries. At the same time, a second support part is provided on the upper rear surface of the vacuum cleaner body, which is formed by providing a pair of protrusions with the same protrusion as the protrusions on the left and right ends of the protrusion of the lid body on the rear surface of the vacuum cleaner body. Because it was provided at a lower position of the vacuum cleaner body than the first support part formed,
When the vacuum cleaner body is placed with its rear side down, the protrusion for opening and closing the lid does not receive any impact, the lid does not bend or deform, and it is possible to prevent poor contact due to battery movement. The lower protrusion of the vacuum cleaner body is continuous with both ends of the protrusion of the lid, and can be used as a handhold when opening and closing the lid.
The lid can be opened and closed easily, and when the vacuum cleaner is placed upright, the knob protrusion on the lid comes into contact with the floor together with the protrusion on the vacuum cleaner, which prevents shock from the battery. It is possible to prevent the cover from bending and deforming due to the movement of the battery, and to prevent poor contact due to movement of the battery.Furthermore, the lower protrusion of the vacuum cleaner body and both ends of the protrusion of the cover are continuous and can be supported. It becomes more stable.
