Description

TECHNICAL FIELD The present invention relates to an electric vacuum cleaner capable of accommodating accessory application parts such as a suction port.

[Conventional technology]

This type of vacuum cleaner, as shown in JP-B-44-25658 and JP-B-52-15094, has a cleaner body in which a dust collecting chamber, an electric blower chamber and an exhaust chamber are integrally formed, A structure is known in which a storage portion for accessory application parts is formed and the storage portion is covered with a lid.

Further, as shown in Japanese Patent Application Laid-Open No. 57-3615, there is also known one in which a hose is housed in a dust collecting chamber constituting a cleaner body.

[Problems to be Solved by the Invention]

As described above, the conventional technique has a structure in which the vacuum cleaner body is provided with the component storage portion, which has a drawback that the structure is complicated.

In other words, the individual parts that make up the electric blower, the dust collection chamber, the exhaust chamber, etc. are directly assembled and fixed to the cleaner body to assemble the whole, and the large cleaner body is assembled at the beginning of the assembly process. It is necessary to handle from the beginning, and when the process of assembling up to the parts storage part is included, it becomes a very large number of processes, so not only the operability at the time of the process is bad, but also the parts supply management becomes complicated and the process is divided. However, there is a drawback that a large assembling place (long assembling line) is required because it is not possible.

Further, the main body of the vacuum cleaner having the component storage portion functions as a case for holding and protecting the storage components, and since considerable strength is required from the viewpoint of strength, the entire structure becomes thick or unnecessary parts are removed. However, there was a drawback that the size had to be increased.

In addition, since the cleaner body is also an external component, it is not possible to select a free shape from the above strength and structural constraints when designing the shape, and sacrifice the handleability of the cleaner. There was a flaw that didn't happen.

In addition, since each part is directly assembled to the cleaner body as described above, when changing the model to a model with a different external shape or expanding the model to multiple models where the external shape differs from the stored parts, It is necessary to design the main body of the vacuum cleaner exclusively, and especially the design of the mounting part of the electric blower, which is an electrical component, and the design of the dust collecting part and the exhaust part, which require a lot of effort to study noise and suction performance. It wasn't economically feasible to repeat, and it was virtually impossible.

An object of the present invention is to provide a portable electric vacuum cleaner which can solve the above-mentioned drawbacks, is excellent in productivity and handleability, and can be downsized.

[Means for Solving the Problems]

The above-mentioned object has a cleaner body formed by unitizing a dust collection chamber, an electric blower chamber, and an exhaust chamber, and a bag-shaped storage case for storing the cleaner body and accessories for the cleaning device. The main body case includes a horizontally long main body case to which the main body of the vacuum cleaner is detachably attached, and a lid case which is openably and closably coupled to the main body case by a hinge and closes an opening of the main body case. An electric vacuum cleaner in which the vacuum cleaner body is arranged on the hinge side in a staggered manner, and the outer casing of the vacuum cleaner body and the lid case face each other in close proximity when the lid case is closed. Is provided with an intake opening formed by denting a part of the joint surface between the lid case and the main body case on one side surface thereof, and the other side surface of the other side surface of the storage case. , The lid case The recessing a part of the bonding surface of the main body case provided with elongated exhaust opening obtained by forming, the size precepts along an outer shell of the exhaust chamber to the exhaust opening, and,
The outer hose of the exhaust chamber is fitted into the exhaust opening, and a suction hose communicating with the dust collecting chamber is pulled out from the intake opening with the opening of the main body case covered with the lid case. It is achieved by being possible.

[Action]

Since the cleaner body having the dust collection chamber, the electric blower chamber and the exhaust chamber is housed in the storage case and is detachably mounted with screws or the like, the cleaner body itself is a unit having a cleaner function. As a result, only the minimum parts related to this part need be handled, and it is not necessary to handle a storage case or other accessory application parts that are large parts that are not directly related.

To attach the vacuum cleaner body to the storage case, it is sufficient to attach the vacuum cleaner body that is completed at the same level as other applied parts such as other suction holes, and the process of installing the components inside the storage case, which is the final step, is simplified. .

Since the main body of the vacuum cleaner is no longer a design external part and is protected by the storage case, it can be made to have the minimum required strength, and the shape can also be made the minimum size according to the built-in parts. The size, weight and weight can be reduced.

On the other hand, the storage case allows the cleaner body to be handled as a single large storage unit as a unit, and the design shape as an external component can be determined separately from the storage component, with an emphasis on handleability. It is possible to select a shape with a high degree of freedom.

In addition, since it is possible to handle the vacuum cleaner body as a common unit when deploying to models with different storage case shapes, only the storage case part needs to be designed, greatly reducing the labor required for development. it can.

Further, the outer wall of the exhaust chamber of the cleaner body is fitted into the exhaust opening of the storage case, and the dimension of the storage case in the horizontal direction is reduced by the amount of the fitting, and the cleaner body is closed when the lid case is closed. Since the lid case and the lid case closely face each other and the thickness dimension of the storage case becomes small, the storage case can be made compact and lightweight.

It shows a state in which it is opened 0 °. In this state, the applied parts housed inside each have an opening on the entire surface, so that the housed position can be identified at a glance. Also, because it is stably placed on a flat surface such as the floor, it is easy to take out and store it.

As shown in the figure, the hose 16 and the swivel joint 17 are arranged near the joint surface between the main body case 3 and the lid case 4, that is, near the center of the storage case 1 where the depths are almost the same, but due to their own weight, Since it deforms along the main body case 3 side, if it is bent and stored along the shape of the inner wall of the main body case 3 at the time of storage, it is stable even if the hose 16 has a repulsive force and a force to expand. The lid case 4 can be stored and held in shape, and does not get in the way when the lid case 4 is closed.

Further, since the dust collecting chamber lid 36 is in a state of protruding from the opening surface of the main body case 3, it is easy to visually confirm, and the work of opening the dust collecting chamber 13 and the work of attaching and removing the dust collecting bag 12 are excellent. Becomes

With the above-described structure, the components housed as shown in FIG. 4 are the components housed in the inner surface of the main body case 3 and the lid case 4.
Since the hose 16 is arranged so as to be sandwiched between the hose 16 and the parts stored on the inner surface of the hose 16, even if the hose 16 is tilted in each direction when carrying it and is subjected to an impact, You won't get chilled. On the contrary, each applied component is fitted into the recess 50 of the storage case 1 and is temporarily fixed. However, by sandwiching the hose 16 as described above, each component is also recessed in the main body case 3 and the lid case 4. It will be pressed against the 50 side and will not come off if an external force is applied due to an impact.

Heavy parts such as the floor suction port 24 are likely to come off when an impact is applied. Therefore, as shown in FIG.
If it is sandwiched between the recess 39 and the recess 39, it can be firmly held. In addition, a large part such as the floor suction port 24 has a volume of a portion that does not interfere even if the cleaner body 10 is provided with the recess 39, like the small-diameter portion of the electric blower 11 in the cleaner body 10 as described above. The volume of the storage case 1 can be minimized by positively utilizing.

On the other hand, the applied mouthpiece 22 for the gap is, as can be seen from FIG.
It is an undercut portion between the cleaner body 10 having a substantially circular cross section and the lid case 4, which incorporates the electric blower 11, and is provided at a recessed position by utilizing the storage recess, so that the space volume is reduced. Since it can be effectively used and can be pressed from above by the cleaner body 10, it can be firmly held, and is particularly effective when accommodating and holding a small and heavy component.

With the above-described configuration, the main body case 3 and the lid case 4 can be housed in a small size while accommodating the vacuum cleaner body 10 and various applied parts, and by combining the hose 16 having the swivel joint 17 and the lid body 28. The hose 16 can be taken out of the storage case 1 in a closed, so-called bag-like assembled state to perform a vacuum cleaner operation. From this, as the usage mode, as shown in FIG. 13, the stationary type in which the legs 37 are in contact, the floor moving type in which the casters 19 are installed as in FIG. 14, and the hook portion of the Charder band 38 as in FIG. 40 is a shoulder-hanging type that engages with a hook 41 provided on the storage case 1 side, and as shown in FIG. 16, a band is provided between the hook 42 provided on the handle 7 side and the hook (not shown) provided on the leg 37 side. It can be formed into a backpack shape by multiplying by 43.
Also in each form, the floor surface or each surface of the storage case 1 in contact with the human body can be configured so as not to have any protruding projections or irregularities, and the outlet of the hose 16 or the direction of exhaust from the exhaust chamber 15 , Even in each usage mode,
It is a suitable arrangement that does not cause discomfort to the human body.

Of course, as shown in FIG. 1, it is also possible to pull out the hose 16 with the main body case 3 and the lid case 4 and use it as it is.

In the present embodiment, an example in which the intake hose 16 can be pulled out of the storage case 1 without being attached or detached has been shown. However, as shown in the schematic diagram of FIG. 17, the intake opening faces the intake port 50 of the dust collection chamber 13. The same effect can be obtained by providing 51 and attaching and detaching the hose 52 from the opening 51.

〔The invention's effect〕

According to the present invention, the following effects can be obtained.

(1) Assembling the vacuum cleaner body, manufacturing other applied accessory parts, and manufacturing the storage case can be separately controlled for production, and in the final process, store the assembled parts in the storage case. It will be possible to greatly streamline production management and economic aspects, such as enabling production in the final department and reducing the number of parts to be assembled in the final process.

(2) From the viewpoint of quality control such as performance testing, it can be performed for each storage component. Especially, since the quality of the vacuum cleaner body can be checked before it is installed in the storage case, it has a great effect on quality improvement.

(3) As described above, for each part, only the minimum related parts related to each part need to be assembled, and the assembling property can be greatly improved.

(4) Since the vacuum cleaner body is protected by the storage case, it can be made thinner and lighter. Further, since it is not an external appearance design part, it is possible to delete the unnecessary space portion and effectively use it, thereby enabling downsizing.

(5) Since the vacuum cleaner body is unitized as an assembly, the shape of the storage case can be decided freely without being restricted by the detailed shape for mounting the vacuum cleaner body, and therefore the external design can be determined. A large shape can be selected.

(6) When deploying to models with different storage case shapes, the vacuum cleaner body can be stored as a common unit, and only the storage case needs to be designed, so the labor required for development can be greatly reduced.

(7) The outer wall of the exhaust chamber of the vacuum cleaner body fits into the exhaust opening of the storage case, which reduces the horizontal dimension of the storage case by the amount of the fitting, and cleans when the lid case is closed. Since the machine body and the lid case are close to each other and the heat dimension of the storage case is small, the storage case can be made compact and lightweight.
