Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a vacuum cleaner used at home, etc., and particularly relates to a vacuum cleaner for use in suction, which is an accessory connected to the main body of the vacuum cleaner. This invention relates to a structure for housing a hose, an extension pipe, and a suction port body.

(Prior Art) Conventionally, this type of vacuum cleaner has a structure in which accessories such as hoses, extension pipes, and suction ports that have been removed from the vacuum cleaner body or from each other are stored in an accessory storage box. was taken. However, with this conventional structure, the user does not always put each accessory in the designated position in the storage box, so it may not be possible to fit all the accessories into the storage box, or if the accessories are forced into the storage box. It could cause damage. Furthermore, when starting and finishing cleaning, the vacuum cleaner main body, hose, extension pipe, and suction port body must be connected and disconnected from each other, which is time-consuming.

Therefore, as shown in FIG. 10, a ring-shaped hose holder 2 and an extension tube holder 3, which are detachably attached to the upper surface of the vacuum cleaner main body 1, are used to maintain the connection to the vacuum cleaner main body 1. The hose 4 and the extension tube 6, which has been detached from the hose 4 but the suction port body 5 remains connected, are each detachably held, and the vacuum cleaner main body 1 can be stood upright with its rear face down. Vacuum cleaners are also used that have a structure that allows them to be stored compactly while reducing the effort of attaching and detaching accessories. However, with this conventional structure, it is still necessary to attach and detach the hose 4 and the extension pipe 6, and when it is stored, the heavy suction port body 5 is located on the upper side, raising the overall center of gravity, making it unstable. Bad sex. Furthermore, since the holders 2 and 3 are attached to the upper surface of the vacuum cleaner main body 1, if they are left attached, they become a nuisance when not being stored, and on the other hand, if they are removed, there is a risk that they may be lost.

Therefore, as shown in FIG.
The hoses 8 are bundled by a removable ring-shaped hose holder 11, and the extension tube 9 is removably held by an extension tube holder 12 which is removably attached to the lowermost front part of the vacuum cleaner body 7. 7 with its rear side facing down, and the suction port body 10 is placed close to the ground or the floor, thereby creating a structure that can be stored compactly and with good stability while eliminating the trouble of attaching and detaching accessories. vacuum cleaners are also used. However, in this conventional structure, when the suction port body 10 is not held when it is stored, it may hit the floor surface, which may cause the floor surface to be damaged or dust attached to the suction port body to adhere to the floor surface. Sometimes. Moreover, the holders 11.12 may also get in the way or be lost. Furthermore, if the hoses 8 and the like are long and the position where the hoses 8 are bundled with the hose holder 11 is not appropriate, these hoses 8 and the holder 11
1 and 2 from each other and then adjusting the bundling position, which is time-consuming.

Furthermore, as described in Japanese Utility Model Application Publication No. 54-120262, the vacuum cleaner body, hose, extension tube, and suction port body are connected, and the vacuum cleaner body is placed with its rear side facing down. For compact storage, a groove into which an extension tube can be fitted is formed on the outer periphery of a wheel that is vertically movably supported by a support that is horizontally rotatably supported at the downward front of the vacuum cleaner body. , a vacuum cleaner having a structure in which an extension tube is detachably held on wheels has been proposed. However, in this structure, since the wheel is generally cylindrical, it is difficult to fit the extension pipe into the groove of the wheel. Furthermore, since a groove is formed into which the extension tube fits, the wheel itself must be quite large.

Furthermore, as described in Japanese Utility Model Publication No. 53-40062, the vacuum cleaner body, the hose, the extension tube, and the suction port body are similarly connected, and the vacuum cleaner body is placed with its rear side facing down. In order to store the product compactly, the extension tube is detachably held by an extension tube holder pivoted on the frontmost part of the top surface of the vacuum cleaner body. A vacuum cleaner has also been proposed in which a lid for opening and closing an accessory storage chamber is opened, and a suction port is detachably held from below by the opened lid. However, in this structure, since the suction port body is held by opening the lid body, there is a risk that the accessories stored in the accessory storage chamber may fall out.

In addition, the lid must be opened and closed not only when taking out and putting in accessories from the accessory storage chamber, but also when connecting and disconnecting the suction port from the lid, which increases the number of times the lid is opened and closed.
The support shaft of the lid body tends to wear out.

Furthermore, the holder and the lid must be opened and closed by hand, which is time-consuming and there is a risk of forgetting to close them.

(Problems to be Solved by the Invention) As mentioned above, in particular, the conventional vacuum cleaner can be stored compactly by standing upright the vacuum cleaner body with the vacuum cleaner body, hose, extension pipe, and suction port connected. If the holder is attached to the top of the vacuum cleaner's body, such as an extension tube, the holder will get in the way when it is not being stored, and if the holder is detachable from the vacuum cleaner's body, the holder may be lost. Furthermore, even if the holder is pivoted to the vacuum cleaner body, it takes time and effort to rotate the holder, and it is difficult to fit the extension tube into the groove of the wheel of the vacuum cleaner body. With the holding type, there were problems such as difficulty in fitting the extension tube.

The present invention aims to solve these problems, and the holder of the extension pipe or the suction port does not get in the way except when it is stored, and there is no risk of losing the holder. It is an object of the present invention to provide a vacuum cleaner in which it does not require much effort to operate the body and in which it is easy to engage an extension tube or the like to a holding body.

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

When cleaning, the vacuum cleaner body 21, hose 31 and extension pipe 35 are
and the suction port body 36 are connected to each other. Then, by driving the electric blower, dust sucked in from the dust suction port 37 of the suction port body 36 is captured in the dust collection chamber of the cleaner main body 21 via the extension pipe 35 and the hose 31. At this time, since the wheels 44 of the swinging wheel 41 whose direction is variable and the rear wheel 47 are grounded, the cleaner main body 21 can be easily moved while gripping the grip tube 34 of the hose 31.

When storing the vacuum cleaner after cleaning, as shown in FIG. 1, stand the vacuum cleaner main body 21 with its rear side facing down while the vacuum cleaner main body 21, hose 31, extension pipe 35, and suction port body 36 are connected. It is placed on the floor surface 91 or the like.

Next, operate the handle 78 of the suction port body holder 71 to push down and rotate the suction port body holder 71 so that it protrudes from the lower surface of the vacuum cleaner main body 21.
While inserting the holding piece 75 into the dust suction port 37 of the suction port body 36, the suction port body 36 is placed on the suction port body holder 71 and held.

Next, the suction opening body holder 71 is attached to the suction opening body 36 in this way.
While being held down by the extension tube holder 61, the extension tube holder 61 is lifted and rotated so as to protrude from the support 42 of the turning ring 41, and the extension tube 35 is fitted into the holding part 64 of the extension tube holder 61 and held.

Then, while receiving the load of the suction port body 36 and the like, the suction port body holder 11 is brought into contact with the rear surface of the recess 14 of the vacuum cleaner main body 21 from above, or the handle 78 of this suction port body holder 71 By contacting the floor surface 91, the suction port holder 71 is held in a state protruding from the lower surface of the cleaner main body 21 against the biasing force of the spring 77. Further, by engaging the convex portion 65 of the extension tube holder 61 with the recess 67 of the support 42, the extension tube holder 61 is held in a state protruding from the support 42 against the biasing force of the spring 69. be done.

Further, the hose main body holding portion 82 of the hose holder 81 is fitted to the hose main body 32 via the cut groove 85, and the grip tube holding portion 83 is fitted to the upper portion of the grip tube 34 or the extension tube 35 of the hose 31 through the cut groove 35. By mating through
The hoses 31 are held together in a bundle.

In this way, the hose 31 can be bundled, the extension tube 35 and the suction port body 36 can be placed along the upright vacuum cleaner main body 21, and the vacuum cleaner can be stored compactly. Moreover, since the heavy suction port body 36 is located on the lower side, the stability of the stored state is also good. Further, since the suction port body 36 is held from below by the suction port body holder 71, the dust attached to the suction port body 36 does not adhere to the floor surface 91 after cleaning. Similarly, since the suction port body 71 is positioned floating from the floor surface 91, it is also easy to clean dust attached to the suction port body 11 in the stored state.

In addition, especially when the extension tube 35 is held in the extension tube holder 61, the extension tube 35 is fitted into the holding portion 64 between the distal ends of both sides of the U-shaped extension tube holder 61, so that the rotation ring Compared to the case where the extension tube is fitted into a groove formed in a wheel, fitting is easier, and the extension tube 35 can be more securely positioned and held, so that the extension tube 35 does not wobble. Furthermore, the shape of the holding portion 64 of the extension tube holder 61 can be set relatively freely, and the shape and size of the wheels 44 are not restricted.

Furthermore, since the inner circumferential surface of the hose body holding part 82 of the hose holding body 81 has a spiral waveform surface 87, the hose holding body 81 is firmly held on the hose body 32, and the hose body holding part 82 is Even if the fitting position to the hose body 32 is not appropriate, simply rotate the hose holder 81 or the hose body 32 without removing the hose body holder 82, and the hose body holder 82 can be attached to the hose. It can be moved in the main body 32, and the hose holder 81 will not be lost. Furthermore, at this time, the presence of the brush bristles 88 on the inner circumferential surface of the hose main body holding portion 82 allows dust adhering to the outer circumferential surface of the hose main body 32 to be cleaned, which is convenient.

On the other hand, when starting cleaning, the extension tube 35 is removed from the extension tube holder 61 and the suction port 36 is removed from the suction port holder 71. Then, the load applied to the suction port body holder 71 is removed, and the suction port body holder 71 automatically rotates due to the biasing force of the spring 77, and the vacuum cleaner body 2
It is stored along the bottom surface of 1.

Furthermore, if the extension tube holder 61 is lightly pushed downward to remove the shaft 62 of the extension tube holder 61 from the recess 66 of the support 42, the extension tube holder 61 will be automatically moved by the biasing force of the spring 69. The extension tube holder 61 is rotated to be fitted into the support body 42 and stored, and the convex portion 65 of the extension tube holder 61 is engaged with the concave portion 66 of the support body 42 . That is, no effort is required to return the extension pipe holder 61 and the suction port holder 71 to their storage positions.

Additionally, the hose holder 81 is removed from the hose 31.

Since the cleaner main body 21, the hose 31, the extension pipe 35, and the suction port 36 remain connected, there is no need to reconnect them when starting cleaning.

Further, since the extension tube holder 61 and the suction port holder 71 are located on the lower surface of the cleaner main body 21 and housed as described above, they do not get in the way during cleaning. Moreover, since the extension pipe holder 61 and the suction port holder 71 are securely held in the storage position by the springs 69 and 77, they may come into contact with the floor surface etc. during cleaning and damage the floor surface. There is no need to worry.

The extension tube holder 61 and the suction port holder 71 are
Since it is always attached to the vacuum cleaner main body 21, it never gets lost.

Further, since the extension tube holder 61 is supported on the support 42 of the turning ring 41 and the suction port holder 71 is supported on the support shaft 49 of the rear wheel 47, a structure with no waste can be achieved.

Note that the suction port holder 71 is attached to the rear wheel 4 including the handle 78.
The rear wheel 47 may be placed within the circumference of the rear wheel 47 when viewed from the axial direction of the rear wheel 47. With this structure, even if the suction port holder 71 rotates in the protruding direction for some reason during cleaning, it will not come into contact with the floor surface.

The hose holder 81 also has a cylindrical holding portion 82.
．． 83 may be connected three or more.

Then, a spiral wavy surface 87 is formed on the inner peripheral surface, and the brush bristles 8
8 may be implanted in two or more hose main body holding parts 82.

〔Effect of the invention〕

According to the present invention, the extension tube holder is rotatably supported on the support of the swing wheel provided on the vacuum cleaner body, and the suction port holder is supported on the support shaft of the rear wheel provided on the vacuum cleaner body. Since they are rotatably supported, both holders will not be lost and the structure will be streamlined.Moreover, the extension tube holder is fitted into the support located on the bottom of the vacuum cleaner body. The suction port holder is also stored on the bottom of the vacuum cleaner body, so it does not get in the way except when it is being stored. Since the extension tube is biased in the direction, it is time-consuming to return it to the storage position from the position where it protrudes from the support body to hold the extension tube and from the position where it protrudes from the bottom surface of the vacuum cleaner body to hold the suction port body. Not only does it not hang, it also prevents it from rotating from its storage position during cleaning and damaging the floor. Furthermore, compared to the case where the wheels of the slewing ring are provided with grooves into which the extension pipe fits, the shape of the extension pipe holder can be set relatively freely, making it easier to engage the extension pipe with the extension pipe holder. You can make it possible to match.
