Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a vacuum cleaner in which a set of parts such as a hose and a suction mouth are housed in a bag-like main body case, and in particular, the internal main body may be damaged by shocks such as when being carried. It relates to a structure that prevents movement or detachment of fixed parts.

[Conventional technology]

In the case of a conventional portable vacuum cleaner in which a set of application parts is housed, consideration has been given to the storage arrangement, as in Japanese Utility Model Publication No. 44-25658.

No consideration was given to preventing movement or detachment of the fixed portion due to impact during carrying.

[Problem that the invention seeks to solve]

As mentioned above, in the conventional technology, no consideration was given to stably holding the internal components, especially the heaviest internal body, and there were problems such as damage to the fixed parts and the loosening and damage of the fixing screw parts. .

The object of the present invention is to relate to a structure for stably holding this internal body.

[Means for solving problems]

The above object is achieved by using a bag-like main body case that can be opened and closed and has a hinge such as a hinge, and has a structure in which the inner main body is clamped or enclosed at a close distance when the main body case is in a closed state.

[Effect]

When carrying the entire case of a portaple vacuum cleaner,
When collided or dropped, a large impact force acts on the internal body that is fixed inside, but the internal body is clamped on the inner surface of the main body case, and the entire body disperses and supports the WI impact force. This prevents a large force from being applied only to the fixed parts of the internal body.

Even when this is enclosed at a close distance, it is held by the inner surface of the main body case with deformation only by the minute gap, so damage to the fixed part can be similarly prevented.

FIG. 11 is a sectional view including the exhaust pipe 14, which is suitable for bending and storing flexible small parts such as the shoulder band 38 in the space between the main body case 3 and the exhaust pipe. be.

FIG. 12 is a cross-sectional view showing the main body cases 3 and 4 in an open state, and can be opened approximately 180° by the hinge 2 and leg portions 37. In this state, the applied parts stored inside are fully open, allowing you to see and identify the storage location.Also, since they are placed stably on a flat surface such as the floor, it is easy to take them out and store them. It's easy to do.

As shown in the figure, the hose 16 and swivel joint 17 are arranged near the dividing plane of the main cases 3 and 4, that is, near the center plane, but because of their own weight, they deform along the main case 3 side, so when stored, the main body case If the hose 16 is bent and stored along the shape of the inner wall of 3, even when the hose 16 has a repulsive force and tries to expand, it can be stored and kept in shape stably, even when the main body case 4 is closed. It won't get in the way by getting stuck in it.

In addition, since the dust collection part lid body 36 protrudes from the opening surface of the main body case 3, visual confirmation is easy, and the work of opening and closing the dust collection part 13 and the installation and removal of the dust collection bag 12 is easy. becomes.

With the above configuration, the parts stored as shown in FIG.
Since the hose 16 is sandwiched between the parts stored on the inner surface of the housing, the hose 16 will not get tangled or tangled even if the main body case 1 is tilted in any direction or subjected to impact when being carried. On the other hand, each application part is
Although it is fitted and temporarily fixed in the recess of the main body case, by holding the hose 16 as described above, each part is also pressed against the recess of the main body case 3, 4, and external force is applied due to impact. In this case, it will not come off.

However, heavy parts such as the floor suction port 24.

Since it is easy to come off when an impact is applied, it can be firmly held by holding it between the recesses 39 provided in the internal body 10 as shown in FIG. In addition, for large parts such as the floor suction port 24, the volume of the part that will not interfere even if the recess 39 is provided in the internal body, such as the small diameter part of the electric blower 11 in the internal body 10 as described above, is actively reduced. By utilizing this, the volume of the main body case 1 can be minimized.

The internal body 1o also holds the floor suction port 24 as described above, and is also held on the inner walls of the main body cases 3 and 4, and further abuts on the inner surface of the main body case 3.4 on the hinge 2 side. Even if an impact is applied in each direction, the entire structure is distributed and supported.

On the other hand, as shown in FIG. 4, the gap opening 22 is inserted into the undercut between the internal body 10 with a circular cross section and the body case 4, which houses the electric blower 11. It is provided with a recessed part for storage, so that the space volume can be used effectively, and at the same time, it can be held firmly because it can be pressed from above by the internal body 10.
This is especially effective when storing and holding small but heavy parts.

With the above configuration, the internal main body 10 and various applied parts can be stored in spite of the small size, and the main body cases 3 and 4 are closed by the combination of the hose 16 having the swivel joint 17 and the lid body 28. Cleaning work can be performed by taking the hose 16 out of the main case 1 in a so-called sheath-like assembled state. From this, the first usage pattern is
A stationary type with the legs 37 grounded as shown in Fig. 3, a spherical type with the casters 19 grounded as shown in Fig. 14, and a hook part 40 of the shoulder band 38 provided on the main body case 1 side as shown in Fig. 15. Engaged with the hook 41, the shoulder rest is shaped, and the 16th
As shown in the figure, a band 43 can be hung between a hook 42 on the handle 7 side and a hook (not shown) provided on the leg 37 side to make it carryable on the back. In each form, each surface of the main body case 1 that comes into contact with the floor or the human body can be configured without any obstructive protrusions or unevenness, and the direction of exhaust from the outlet of the hose 16 or the exhaust chamber 15 is It has a suitable arrangement that does not get in the way or cause discomfort to the human body in each usage mode.

Of course, it is also possible to pull out the hose 16 with the main body case 3.4 open and use it as is, as shown in FIG.

〔Effect of the invention〕

According to the present invention, the inner main body, which is the heaviest storage component, can be clamped and held on the inner wall of the dry main body case, and force is not applied only to the fixing portion of the inner main body to the main body case. Since the entire structure is evenly supported, there is no problem of damage to the mounting and fixing parts even if a large external force such as a fall or collision is applied.

On the other hand, the mounting and fixing part does not require great strength, so it is possible to reduce the wall thickness of the internal body and the number of fixing screws.
It is highly effective in reducing weight and improving economic efficiency.

In addition, the internal body and the inner wall of the main body case are in close contact or have only a small gap, which eliminates wasted space, making it possible to downsize the entire main body case and reduce weight.
Economic efficiency can be improved by improving handling and reducing the amount of materials used.
