  In an ordinary passenger car or the like, it is not preferable to dispose a suction device of a vehicle interior cleaning device in the vehicle interior from the viewpoint of effectively using a limited volume of the vehicle interior as much as possible. In addition, it is not preferable to arrange the suction device in the trunk room because the capacity of the trunk room is reduced. In addition, a lot of mechanical devices necessary for driving and operating an automobile are accommodated under the floor, and the space is small, and it is a place that is susceptible to external impacts. . In these respects, the above-described interior cleaning devices of Patent Documents 1 to 13 have problems from the viewpoint of effective use of the interior space because the suction device is arranged in the interior of the vehicle, under the floor, or in the trunk room.

  Moreover, it is necessary for the vehicle interior cleaning apparatus of patent documents 1-14 to always have an apparatus in a vehicle body for the limited use of vehicle interior cleaning. Since the cleaning work is not always performed, it is more reasonable to carry out cleaning by bringing a vacuum cleaner when necessary. It is considered unreasonable to always install a device only for cleaning work in a limited vehicle interior space. Further, the range that can be cleaned is limited to the interior of the vehicle, and no consideration is given to cleaning the outside of the vehicle or the trunk room.

  Therefore, an object of the present invention is not to occupy a limited vehicle interior space, and is not limited to vehicle interior cleaning, but can be used for vehicle interior cleaning applications even during normal operation. It is to provide a cleaning device.

  Another object of the present invention is to provide an in-vehicle cleaning apparatus that can be used not only in the interior space of a vehicle but also when cleaning the outside of a vehicle or a trunk room.

A first configuration of an on-vehicle cleaning device according to the present invention is an on-vehicle cleaning device that is installed in an automobile and used for ventilation and cleaning of the interior of the automobile,
A ceiling joint attached to an exhaust port penetrating the ceiling of the vehicle compartment;
A suction fan which is installed outside the ceiling of the automobile and discharges air sucked from the suction port toward the outside air from the exhaust port;
A fan connecting pipe connecting the outdoor side of the ceiling joint and the suction side port of the suction fan;

Since the vehicle-mounted cleaning device is attached to the ceiling of the passenger compartment, when a smoker is in the vehicle, purple smoke generated by smoking can be sucked to the ceiling and exhausted. A typical automobile is also equipped with a ventilator, but the exhaust is located behind the rear seat or in the trunk room. In this case, if the smoker is on the front seat, the purple smoke flows toward the rear seat and diffuses throughout the room. On the other hand, since the in-vehicle cleaning device of the present invention sucks purple smoke from the ceiling of the vehicle interior, the purple smoke can be discharged outside without being diffused much in the room. Further, as described above, since it is used not only for cleaning the interior of the vehicle but also for ventilating the interior of the vehicle, the on-vehicle cleaning device of the present invention can be used during normal operation and is always installed on the vehicle body.

And the side tube branched and connected in a T-shape to the side surface of the outer tube.

  According to this configuration, if the outer tube is rotated to a position where the opening on the side surface of the main tube and the side tube of the outer tube communicate with each other, the fan connecting tube does not communicate with the side tube, and the indoor side of the ceiling joint Communicate. Thereby, the vehicle-mounted cleaning apparatus of this invention can be used for the ventilation of a vehicle interior, or the cleaning of a vehicle interior. Further, when the outer tube is rotated to a position where the opening on the side surface of the main tube and the side tube of the outer tube communicate with each other, the side tube communicates with the fan connecting tube. In this case, the in-vehicle cleaning device of the present invention is used for cleaning the trunk room outside and at the rear by connecting a flexible hose for cleaning to the side pipe and closing it by installing a closing lid on the indoor side of the ceiling joint. I can do it.

According to a fourth configuration of the in-vehicle cleaning device according to the present invention, in the second configuration, the branch pipe is provided at a connection portion between the ceiling joint and the fan connecting pipe instead of the main pipe. Equipped with a three-way valve
The output side port of the three-way valve is connected to the fan connecting pipe,
One input side port of the three-way valve is connected to the ceiling joint,

  About the vehicle-mounted cleaning apparatus 1 of this Example 1 comprised as mentioned above, the operation | movement and usage method are demonstrated below.

  First, when the vehicle-mounted cleaning device 1 is used as a cleaner for cleaning the vehicle interior, the ceiling joint of the vehicle interior ceiling is in a state where the outer tube 5b of the branch tube 5 is in a position where the side tube 5c and the main tube 5a do not communicate with each other. The flexible hose 10 is connected to 7. Thereby, it can be used like a normal vacuum cleaner. At this time, the on / off operation of the suction device 3 and the operation of the suction pressure of the suction device 3 are performed by operating the remote controller 3j. When an instruction to turn on the suction device 3 is input from the remote controller 3j, the drive circuit 3i activates the motor 3b at a speed set by the remote controller 3j and releases the shutter 2d. When an instruction to turn on the suction device 3 is input from the remote controller 3j, the drive circuit 3i stops the motor 3b and closes the shutter 2d. Thereby, it is possible to prevent rainwater, dust, etc. from entering the shutter 2d when the suction device 3 is stopped. At this time, it is preferable to close the side pipe joint 5d at the tip of the side pipe 5c of the branch pipe 5 by attaching a closing lid 11 thereto. Since the closing lid 11 is not normally used, it can be prevented from being lost if it is attached to the side pipe joint 5d.

  When the interior of the vehicle interior is ventilated by the vehicle-mounted cleaning device 1, nothing is connected to the ceiling joint 7 of the vehicle compartment ceiling, or the ventilation lid 12 is attached to the ceiling joint 7 of the vehicle interior ceiling. What is necessary is just to start the suction apparatus 3 in the mounted state. Thereby, vehicle interior ventilation is performed. In particular, when smoking is carried out in the passenger compartment, the purple smoke generated by smoking moves to the vicinity of the passenger compartment ceiling, but because the inlet 9 is on the ceiling, the smoke is quickly ventilated before it spreads throughout the passenger compartment. Indoor air can be kept clean. Since the suction device 3 can be operated by a remote controller 3j installed in the passenger compartment, the suction device 3 can be turned on / off and the suction pressure can be adjusted even during operation.

  Next, when used as a vacuum cleaner for cleaning outside the passenger compartment, the ceiling joint 7 on the ceiling of the passenger compartment is closed with a closing lid 11, and the outer tube 5b of the branch pipe 5 is rotated to turn the side pipe 5c into the main pipe 5a. Communicate. And the flexible hose 10 is connected to the side pipe joint 5d of the front-end | tip of the side pipe 5c. Thereby, it can be used like a normal vacuum cleaner. Since the vehicle-mounted cleaning device 1 is installed on the roof of the vehicle, it is easy to extend the flexible hose 10 to the trunk room in the case of a light passenger car or a normal passenger car. Cleaning can also be performed. It can also be used for applications such as sucking and removing water droplets adhering to the vehicle body after washing.

The first input port pipe 20c is connected to the ceiling joint 7, and the side pipe joint 20e is connected to the tip of the second input port pipe 20d. The side pipe joint 20e is the same as the side pipe joint 5d of the first embodiment.

  FIG. 7 is an exploded perspective view of the branch pipe (three-way valve) 20. FIG. 8 is a sectional view of the branch pipe (three-way valve) 20. FIG. 8A shows a state in which the ventilation path of the second input port pipe 20d and the ventilation path of the valve chamber communicate smoothly, and FIG. 8B shows the ventilation path of the first input port pipe 20c and the valve chamber. The air passage is in smooth communication. The valve housing 20a has a first input port tube 20c and a second input port tube 20d projecting symmetrically with respect to the central axis on the side surface in the vicinity of the blind end side of the center housing of the blind end cylindrical shape. It is formed in a T shape. A cylindrical valve chamber is formed inside the central housing. The first input port pipe 20c and the second input port pipe 20d are cylindrical, and a ventilation path is formed at the center. The valve body 20b has a stepped cylindrical shape and has a ventilation pipe formed therein, and the ventilation pipe on the side inside the valve casing 20a is curved. In addition, the vent path communicating from the first input port pipe 20c to the valve chamber is curved toward the valve chamber outlet side before the valve chamber, and the vent path communicating from the second input port pipe 20d to the valve chamber is: Similarly, it curves toward the valve chamber outlet side before the valve chamber. Moreover, the internal diameter of both aeration paths is the same diameter as the internal diameter of the ventilation path in the valve body 20b. A portion of the valve body 20b protruding from the valve chamber has a stepped diameter, and this portion serves as a valve shaft portion 20g. And the output port pipe | tube 20f is shown by covering by this valve-shaft part 20g. An annular plate-like flange 20i is formed on the base end side of the output port tube 20f, and a projection 20k near the periphery of the flange 20i is fitted into the periphery of the valve chamber opening end of the valve housing 20a. The valve body 20b is provided with an operation handle 20h protruding from the side surface of the valve stem 20g, and the operation handle 20h can be moved to the side surface near the flange 20i on the proximal end side of the output port pipe 20f. An opening 20k is formed. The valve body 20b can be rotated by picking the operation handle 20h.

  When the valve body 20b is rotated to a position where the air passage in the valve body 20b is curved upward, the air passage in the valve body 20b and the air passage communicating with the valve chamber from the second input port pipe 20d Communicate smoothly (see FIG. 8A). Further, when the valve body 20b is rotated 180 degrees from that position and the air passage in the valve body 20b is curved downward, the air passage in the valve body 20b and the first input port pipe 20c are connected to the valve chamber. The air passage communicating with the air smoothly communicates (see FIG. 8B).

  Thus, by using the branch pipe 20 as a three-way valve, the closing lid 11 described in the first embodiment is not necessary, and convenience is further improved.
