This is a so-called stand-storable electric appliance that allows the vacuum cleaner body to be stored upright with its rear side facing down while the vacuum cleaner body, hose, extension pipe, and suction port remain connected to each other. Vacuum cleaners are known. In this conventional vacuum cleaner, a protrusion is integrally provided with a hook fixed to the outside of the extension tube, and this protrusion is removably fitted inside the extension tube to be locked. The vacuum cleaner had a structure in which a hook case with an open front was integrally protruded from the top of the vacuum cleaner body.

(Problem to be Solved by the Invention) However, in the above conventional structure, the part of the locking tool that is fixed to the extension tube and the part that is locked to the vacuum cleaner body, that is, the protrusion, are integrated. Although this protrusion does not function during actual cleaning, due to the shape and volume of this protrusion that is always protruding, it becomes a hindrance and prevents operations during cleaning. There was a problem of decreased sex. Additionally, the hook case was always protruding from the top of the vacuum cleaner, which got in the way when cleaning. In other words, there is a risk that the protrusion or the hook case may collide with the furniture being cleaned, which may impede the movement of the vacuum cleaner or damage the locking device, the hook case, or the furniture that was struck. there were.

The present invention aims to solve the above-mentioned problems, and the purpose of the present invention is to ensure that the locking tool for storing the stand does not get in the way during cleaning.
It is an object of the present invention to provide a vacuum cleaner that has good operability when cleaning and also has good operability when stored in a stand.

In addition, the present invention aims to improve manufacturability, operability, and design in a vacuum cleaner that can be stored in a storage case as well as a stand.

[Structure of the invention]

A suction port detachably connected to the other end, the vacuum cleaner main body, the hose, the extension pipe, and the suction port are connected to each other, and the vacuum cleaner main body is connected to the vacuum cleaner main body in the front and back direction of the vacuum cleaner main body. A vacuum cleaner comprising: a locking device for detachably holding the extension tube along the line; and a rotating member which is rotatably connected with the direction along the extension tube as the rotational axis direction and has a locking convex portion, and whose shape can be changed when cleaning and when storing the stand, and on the other hand. The front surface of the vacuum cleaner main body is provided with a groove open to the front, into which the locking protrusion of the rotating member of the locking tool is removably fitted and locked.

In addition, a storage case is provided that is open upward, in which the hose, extension pipe, and suction port removed from the vacuum cleaner body are stored, and the lower part of the vacuum cleaner body is removably inserted into the upper part. The storage case has a movable clamp body on the upper front surface, and the vacuum cleaner main body has a locking recess opened to the front, in which the clamp body is removably engaged, on the lower front surface. In order to achieve the latter purpose in a vacuum cleaner having a
It is preferable that a groove into which the locking convex portion of the rotating member of the locking tool is fitted is provided continuously to the locking recess.

(Function) In the vacuum cleaner of the present invention, when cleaning, one end of the hose is connected to the main body of the vacuum cleaner, one end of the extension tube is connected to the other end of the hose, and the other end of the extension tube is connected to the other end of the hose. While connecting the suction port body, the suction port body and the cleaner body are moved as appropriate on the surface to be cleaned by holding, for example, the grip portion at the other end of the hose. Then, by driving the electric blower inside the vacuum cleaner body, dust is sucked in through the suction port body, guided into the dust collection chamber of the vacuum cleaner body via the extension pipe and the hose, and captured. During such cleaning, the rotating member is rotated around the rotation axis along the extension tube relative to the fixing member of the locking tool fixed to the outside of the extension tube. If the movable member is stored, this rotary member will not interfere with the running operation of the suction port body. On the other hand, when storing the vacuum cleaner, the vacuum cleaner main body is placed vertically with its rear face facing down, with the vacuum cleaner main body, hose, extension pipe, and suction port body still connected to each other as when cleaning. Next, after rotating the rotating member of the locking tool to project outward from the extension tube,

It is held on the machine body along its front and back direction. To clean again, pull out the locking convex part of the rotating member from the groove on the vacuum cleaner body, remove the extension tube from the cleaner body, and then rotate the rotating member as described above to store it. At the same time, it is only necessary to place the vacuum cleaner main body with its bottom side facing down.

Furthermore, in the vacuum cleaner according to claim 2, when it is desired to store the vacuum cleaner more conveniently than the above-mentioned stand storage, the hose can be removed from the vacuum cleaner body, and the hose, extension pipe, and suction port can be connected together. The hose, extension pipe, and suction port body are separated from each other and stored in a storage case from the top opening thereof. At the same time, the lower part of the vacuum cleaner body is inserted into the upper part of the storage case, but at this time, the clamp body at the upper front of the storage case is engaged with the locking recess at the lower front of the vacuum cleaner body, and the cleaning case is inserted into the storage case. The main body of the machine is locked. When cleaning, remove the clamp body from the locking recess, remove the vacuum cleaner body from the storage case, take out the hose, extension pipe, and suction port body from the storage case, and remove the vacuum cleaner body and hose from the storage case. The extension pipe and the suction port body are interconnected. In addition to storage in the storage case as described above, it can also be stored on a stand, but in this case, since the groove into which the locking protrusion of the locking tool is fitted is continuous with the locking recess, The user does not have to make a mistake in fitting the locking projection.

In attaching the locking member 56, first open the cut groove 59 of the fixed member 57, and insert the round bosses 73 and 74 of the rotating member 58 into the round holes 66 and 67. Further, the fixing member 57 is fitted into the extension tube 36 from its end and slid to a predetermined position. Next, the central protrusion 63 of the fixing member 57
．． 64 with a screw 77 to tighten the fixing member 57 and fix it to the extension tube 36.

Next, the operation of the above embodiment will be explained.

When cleaning, as shown in Figure 1,
Connect the insertion pipe 32 of the hose 31 to the connection port 17 of the hose 31, connect one end of one extension pipe 36 to the hand pipe 33 of this hose 31, and connect the other extension pipe to the other end of this extension pipe 36. 36
One end of the extension pipe 36 is connected to the other end of the extension pipe 36, and a joint pipe 38 of the suction port body 37 is connected to the other end of the extension pipe 36. Also, by hooking your finger on the handle 76 of the rotating member 58 of the locking tool 56, as shown in FIG. The rotating member 58 is rotated to one limit and stored along the extension tube 36. The rotating member 58 is connected to the click convex portion 68 of the fixed member 57.
．． 69, it is fixedly held at the storage position.

Then, the vacuum cleaner itself! 1 rear wheel 21 and swing wheel 2
2 is grounded, hold the grip part 34 of the hose 31, and run the cleaner body 11 and the suction port body 37 as appropriate on the surface to be cleaned. Then, by driving the electric blower 14,
Dust and air are sucked in through the suction port body 37, guided into the dust collection chamber 13 of the cleaner body 11 via the extension pipe 36 and the hose 31, and captured by the dust collection filter. The air filtered by the dust filter passes through the electric blower 14 and is discharged from the exhaust port 19.

At this time, the locking tool 56 is inserted along the extension pipe 36 as described above.
If the rotating member 58 is stored, this rotating member 58 will not get in the way. That is, if the rotating member 58 collides with furniture or when trying to clean under the bed, the rotating member 58 collides with the floor and the suction port body 37 cannot be inserted under the bed. Without a problem,
Easy to operate.

Further, since the engaged portion of the locking tool 56 in the vacuum cleaner body 11 is the groove 25 and does not protrude from the vacuum cleaner body 11, the engaged portion does not collide with a threshold, furniture, etc. Therefore, the engaged part will not be damaged, the threshold or furniture will not be damaged, and the movement of the vacuum cleaner main body H will not be hindered.

On the other hand, when storing the stand after cleaning, for example, the second
As shown in the figure, with the vacuum cleaner main body 11, hose 31, extension pipe 36, and suction port body 37 still connected to each other, hold the handle 23 and hold the vacuum cleaner main body 11.
Stand it with its back facing down.

Further, as shown in FIG. 5, the rotating member 58 of the locking tool 5G
By hooking a finger onto the handle portion 76 of the rotary member 58, the rotary member 58 is rotated to the other limit of the rotation range, and the rotary member 58 is projected outward from the extension tube 36. The rotating member 58 is fixedly held in the protruding position by the click projections 68 and 69 of the fixed member 57. Next, hold the hand tube 33 or the extension tube 36 connected thereto, and as shown in FIG. Then, the locking protrusion 75 on the lower side of the rotating member 58, that is, on the suction port body 37 side, is inserted from above.

As a result, the locking tool 56 is locked to the vacuum cleaner main body 11, and the extension tube 36 is erected in the vertical direction.
is held along. In addition, in this state, the suction port body 37
is also grounded. That is, the locking tool 56 on the extension tube 36
The mounting position is originally set so that the suction port body 37 is grounded. In this way, the cleaner main body 11 and the accessories are housed compactly and with good stability while being connected to each other. In addition, since the groove 25 is shifted to the negative side in the left-right direction on the vacuum cleaner main body 11, the extension tube 36 is also held in a joined state at a position shifted to the negative side in the left-right direction on the lower surface of the vacuum cleaner main body 11. . This is to prevent the turning wheel 22 located at the center in the left-right direction from getting in the way.

To clean again, hold the extension tube 36 or the like and insert the locking protrusion 75 of the rotating member 58 into the groove 25 of the cleaner body 11.
This vacuum cleaner body 11 can be removed by pulling it upward from the
After removing the extension tube 36 from the
It is only necessary to rotate the vacuum cleaner main body 11 and place it along the extension tube 36, and to place the vacuum cleaner main body 11 with its lower surface facing down.

At that time, especially when engaging the locking tool 56 with the vacuum cleaner body 11, hold the extension tube 36 or the like located above the locking tool 56, not the locking tool 56 itself, so that the locking projection 75 of the locking tool 56
can be engaged with the recess l1125 of the cleaner body 11, so there is no need to bend down and this engagement work can be performed easily. That is, if there were a movable locking device on the cleaner body side instead of the extension tube, it would be necessary to bend down to engage the locking device with the extension tube, but there is no need to do so. The same applies when removing the locking tool 56 from the cleaner body 11.

Of course, the fact that the rotating member 58 protrudes from the extension tube 36 itself also contributes to improving the locking operability.

Further, since the handle portion 76 for rotating operation is provided on the upper side of the rotating member 58, that is, on the side of the grip portion 34 that is gripped during cleaning, the rotating member 58 has good operability. That is, the rotating member 58 can be easily operated while holding the grip portion 34 after cleaning or the like.

Furthermore, since the rotating member 58 is fixedly held in the cleaning position and the storage position by the click convex portions 68 and 69, the rotating member 58 does not move accidentally from these predetermined positions. Therefore, the locking operability during storage is improved.

Moreover, when it is desired to carry out more compact storage than the above-mentioned stand storage, the hose 31 is removed from the vacuum cleaner main body 11, and the hose 31, extension pipe 36, and suction port body 37 are separated from each other. The hose 31, the extension pipe 36, and the suction port body 37 are stored in the storage case 41 from its top opening. At the same time, as shown in FIG. 8, the receiver on the rear surface of the vacuum cleaner main body 11 engages the convex portion 26 with the locking piece 50 on the rear surface inside the storage case 41, and the lower part of the vacuum cleaner main body 11 is connected to the storage case 41. 41. Accordingly, while the clamp body 45 of the storage case 41 moves back and forth, the locking protrusion 47 of the clamp body 45 is engaged with the locking recess 24 of the vacuum cleaner main body 11 from the front, and this vacuum cleaner main body 11 It is locked in the storage case 41.

Furthermore, when cleaning, by pressing the button 48 downward, the clamp body 45 is advanced against the spring 46, and the locking convex portion 47 of the clamp body 45 is moved toward the vacuum cleaner main body.
With the handle 23 removed from the locking recess 24 of the vacuum cleaner main body 11, hold the convex portion 26 of the vacuum cleaner main body 11 and insert it into the storage case 41.
Remove the vacuum cleaner main body 11 from the storage case 41 while removing it from the locking piece 50 inside. Next, the hose 31, the extension pipe 36, and the suction port body 37 are taken out from inside the storage case 41, and the cleaner body 11, the hose 31, the extension pipe 36, and the suction port body 37 are connected to each other.

By the way, if the engaging recess into which the clamp body of the storage case is engaged and the groove into which the locking tool for storing the stand is engaged are located separately in the vacuum cleaner body, the user When engaging the locking tool, there is a risk of not knowing whether to engage the locking recess or the groove, and it also looks bad, and when the vacuum cleaner body is molded from synthetic resin, for example, The mold structure becomes complicated. However, according to the above configuration, since the locking recess 24 and the groove 25 are made continuous, it is easy to determine the parking location.
The user can easily engage the locking convex portion 75 of the locking tool 56 without making a mistake in the location.

Moreover, the appearance and design quality is also improved. Furthermore, the vacuum cleaner body 1
In addition to simplifying the structure of 1, the structure of the mold for molding can also be simplified, which is advantageous in terms of manufacturing.

In addition, the engagement recess 2 for the clamp body 45 of the storage case 41
4 and the groove 25 for storing the stand may share a part or all. In order to make these engagement recesses 24 and recess grooves 25 the same, it is necessary to accommodate the fact that the recess grooves 25 are shifted in the left-right direction-lateral direction in the vacuum cleaner main body 11 in order to avoid the turning ring 22. Even in case 41, clamp body 4
5 may be shifted to one side from the center in the left-right direction. Moreover, the turning wheels 22 may not be provided in the center, but the turning wheels 22 may be provided on each of the left and right sides of the cleaner body 11.
