Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention can be used as an ordinary cleaner (vacuum cleaner) as well as when cleaning by blowing off adhering dust, and there is no danger of dust explosion due to sucked copy toner or the like. , A relatively light and compact cleaner with an injection function.

[0002]

2. Description of the Related Art In most cases, dust attached to equipment is
Can be removed together with air by a cleaner. However, in some cases, for example, dust that is blocked in the mesh,
It may be easier to clean dust or the like that is a little damp and adheres hard by blowing a finely squeezed air stream strongly. A long time ago, I replaced the hose with the cleaner air outlet,
A cleaner with a blower function that blows out an air flow was used, but when operating the blower function, the air is discharged from the air outlet to the outside during normal (cleaner) use conditions. The blower function may be used to inject air through a dust bag (sometimes dust may be accumulated inside) or an exhaust filter to prevent dust from coming out, and the jet air may contain small dust. Will disperse minute dust, and now such a model can no longer be seen.

In order to maintain electronic equipment, both an ordinary cleaner (vacuum cleaner) and equipment for injecting compressed air must be carried. Therefore, conventionally, a worker who actually takes charge of maintenance of electronic equipment has spent a great deal of effort to bring a cleaner and an air compressor to the site.

[0004]

SUMMARY OF THE INVENTION The present invention reduces the volume and weight of maintenance equipment to be carried by a worker in charge of maintenance of electronic equipment to the site, and at the same time cleans the electronic equipment to be maintained. At this time, the cleaner and air compressor are not used separately as in the past, but they are slightly larger and heavier than conventional cleaners, but with a switch at hand, it is easy to use an air cleaner for suction type cleaners. Even in a spray type vacuum cleaner,
At times, it is an object of the present invention to provide a convenient cleaner having an injection function, which can be arbitrarily switched and used as a vacuum cleaner capable of performing suction and injection at the same time, and which reliably suppresses the risk of dust explosion.

[0005]

In order to solve the above-mentioned problems, in the present invention, dust is sucked together with air, and the air containing the sucked dust is a dust bag / dust filter having a filter function and an exhaust filter. And a normal cleaner that is cleaned and discharged to the outside by passing through and an air compressor via two clutches that can be arbitrarily switched to either a connected state or a disconnected state by its driving electric motor. The air compressor can also be driven, and the air compressor is added with an injection function of compressing clean air sucked from the outside through an intake filter and injecting it from a nozzle. In practice, it is possible to move only the cleaner air suction fan or the air compressor, or both the cleaner suction fan and the air compressor simultaneously, via the two clutches by switching the hand switch. To be able to
In order to utilize such a function, a cleaning tool in which a compressed air jet nozzle is combined with the central portion of a conical suction tool for a cleaner is created. Further, a diaphragm is provided on the peripheral wall surface of the space for accommodating the dust bag and the dust filter, which is inserted into the air discharge passage containing the dust sucked by the cleaner function, particularly the fine dust such as toner for copying machines. By vibrating the vibrating plate through the hand switch, the fine dust adhering to the inside of the dust bag and dust filter is shaken off to prevent a reduction in suction force, and the suction fan installation space and drive motor installation space By providing a partition wall at the boundary, the air containing fine combustible dust sucked in by the cleaner function is discharged to the outside of the cleaner without approaching the periphery of the motor, and the sparks of the motor commutator generate air containing fine dust. We decided to surely suppress the possibility of a dust explosion.

[0006]

In the cleaning tool according to the present invention, the air compressor and the air suction fan are driven by the same electric motor. Therefore, as in the conventional case, an electric air compressor is carried separately from the ordinary cleaner. Compared to the case, the volume and weight of equipment that maintenance personnel should carry will be smaller, and since independent clutches are installed between the shared electric motor, suction fan, and compressor, By operating the switch, it is convenient that only the cleaner air suction fan or only the air compressor, or both the cleaner suction fan and the air compressor can be operated at the same time. Further, if a cleaning tool in which a compressed air injection nozzle is combined with the central portion of a conical suction tool is used, conventionally, when using a compressed air injection type cleaning tool, dust blown away is as it is.
Although it was released into the air in the room and polluted the room air in a wide range, the dust blown off by the air injection nozzle was immediately sucked into the cleaner from the surrounding suction opening in the above cleaning tool, and It will not pollute the air in a wide area. At present, a copier equipped with a laser beam printer is widely used as an OA device, but the toner for the copier is usually a fine powdery combustible substance, which causes clogging of the cloth in the dust bag. And often caused a decrease in cleaner suction force.
However, when the dust bag / dust filter is housed in the space surrounded by the diaphragm according to the present invention and the diaphragm is vibrated, the toner is shaken off from the cloth in the dust bag, and Clogging is prevented. In addition, even if the probability of occurrence is low, in the case of a normal cleaner, air containing combustible fine dust such as toner causes the cleaner drive motor (usually an AC suitable for rotating the cleaner's exhaust sirocco fan at high speed). (A commutator type motor is used) Since it passed around the commutator that sometimes generates sparks, there was a risk of dust explosion, whereas the space for storing the dust bag and dust filter and the motor installation space Since a partition wall was installed at the boundary between and to prevent dirty air containing toner from going around the electric motor, the possibility of dust explosion was certainly suppressed.

[0008]

As described above, maintenance workers of electronic equipment have conventionally had to carry an independent cleaner (vacuum cleaner) and an air gun with an electric compressor to the maintenance site. However, according to the present invention, the cleaner fan and the air compressor can be operated through the clutch by the single shared motor, so that the quality of the maintenance service can be maintained at the same level as the conventional one and the luggage to be carried should be carried. Both the volume and the weight can be reduced.
