Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning device for an air cleaner for a vehicle.

[0002]

[Prior art]

Since the air cleaner for large vehicles normally processes 40 m ^{2 of} air per minute, the amount of dust adhering to the filter becomes enormous, and if it is used for a long time without cleaning, it will become clogged. This not only reduces the engine output and fuel efficiency, but also scatters harmful exhaust gas around.

For this reason, in maintenance shops and the like, until now, air has been blown from the outside of the air cleaner by an air gun to remove the dust and the like adhering to the surface of the filter in a layered manner. Not only can air not be blown evenly into the inside of the folds, but large dust trapped on the outer surface of the filter cannot be removed only by blowing air from the outside. .

In order to solve such a problem, the apparatus disclosed in Japanese Patent Laid-Open No. 3-267103 by the applicant of the present invention blows pressurized air into the inside of an air cleaner to effectively remove a large amount of dust adhering to the surface. Although it is designed to be peeled off and removed, this device requires a heavy lid because the other end of the air cleaner must be sealed against the pressure applied inside, and the cleaner also needs to be removed. Since the dust removed from the air collects in the cleaning room, it can be scattered outside when the air cleaner is attached or removed, leaving a room for further improvement.

[0005]

[Problems to be solved by the device]

 The present invention has been made in view of these problems, and an object thereof is to provide an improved air cleaner cleaning device that does not scatter removed dust without requiring a heavy lid or the like. To do.

[0006]

[Means for Solving the Problems]

 That is, the present invention, as a cleaning device of an air cleaner for achieving such a problem, connects a closed chamber for accommodating an air filter, which is provided in the main body of the device, to a vacuum dust collector, and at the same time, to the outside of the chamber mainly An air filter mounting member that is equipped with an air inlet and that is driven by a drive motor to rotate, and a large number of air discharge holes that are in sliding contact with the air filter on the mounting member and spray a jet of air on its surface are provided. By disposing such a member, the dust adhering to the surface is efficiently removed by the air flow from the inside of the air filter and the air jet from the outside.

[0007]

【Example】

 Therefore, an embodiment of the present invention will be described below. FIG. 1 shows an embodiment of the present invention. The apparatus main body 1 is composed of an upper chamber 2 for accommodating an air cleaner W to be cleaned and a lower chamber 3 for arranging a drive motor 10. There is.

The upper chamber 2 is configured as a closed chamber provided with a door (not shown) for loading and unloading the air cleaner W on the front side, and an upper part thereof is connected to the duct 4 of the vacuum dust collector to decompress the air inside the chamber. A discharge pipe 5 is provided, and a turntable 7 supported by a bearing 6 is rotatably attached to the lower portion of the upper chamber 2.

The turntable 7 has an air cleaner W mounted thereon and is rotated. A cylinder shaft 8 extending to the lower chamber 3 is integrally fixed to the center of the air cleaner W, and a lower end thereof has a timing A pulley 11 which is rotationally driven by a drive motor 10 via a belt 9 is integrally mounted, and a peripheral surface of the cylindrical shaft 8 extending into the lower chamber 3 is provided inside the air cleaner W. A plurality of air passage holes 12 for introducing air are provided.

On the other hand, a rod 15 is rotatably inserted through the top plate 14 of the upper chamber 2, and a lid 16 attached to the lower end of the rod 15 is configured to seal the upper opening of the air cleaner W. Has been done. The rod 15 is constructed so that it can be pulled up by a wire 17, and a weight 18 can be attached to the rod 15 at an arbitrary position by a screw 18 with a handle. A handle 22 integral with a cam 21 is laterally supported on a base 20 on which the weight 19 is seated. By turning the handle 22, the weight 19 can be lifted from the base 20. It is configured.

By the way, reference numeral 25 in the drawing denotes a pair of air pipes for forcibly wiping off the dust adhering to the surface of the air cleaner W, and a large number of air discharge holes 26 are formed on the inner surfaces of the air pipes 25, 25 facing each other. The air is discharged from the air cleaner W so as to remove the dust adhering in layers on the surface of the air cleaner W.

The air pipe 25 is configured to have a length of 150 mm to 600 mm so as to correspond to each air cleaner W for small vehicles and large vehicles, and the inside of the air pipe 25 is shown in FIG. As shown, a stopper 27 is provided in the center, and for a small air cleaner W, a pressure air is introduced from an air supply pipe 28 connected to the lower end, and this is introduced into the lower half portion of the air pipe 25. For large-sized air cleaner W, pressurized air is introduced from both the air supply pipe 30 at the upper end and the air supply pipe 28 at the lower end and is discharged from the entire air pipe 25. Therefore, the air supply pipes 28, 30 are provided with valves 29, 31 for cutting off the supply of the pressurized air.

These air pipes 25, 25 are supported by a support arm 33 pivotably supported on the inner wall surface of the upper chamber 2 so as to be able to follow the peripheral surfaces of the large and small air cleaners W equally, and further, The free end of the support arm 33 is given a habit of always moving toward the peripheral surface of the air cleaner W by its own weight of the weight 35 suspended via the wire 34. Reference numeral 32 in the drawing denotes a floating ring attached to the central portion of the air pipe 25 in the longitudinal direction in order to weaken sliding resistance between the air cleaner W and the air cleaner W.

This embodiment is configured as described above, and when cleaning the air cleaner W using this apparatus, first, the pair of air pipes 25, 25 supported by the support arms 33, 33 is first. The air cleaner W to be cleaned is placed on the turntable 7 so as to be retracted to the outside.

As a result, the pair of support arms 33, 33, to which the inward turning habit is imparted by the weight 35, bring the supported air pipes 25, 25 into contact with the peripheral surface of the air cleaner W. The rod 15 is lowered and a lid 16 attached to the lower end of the rod 15 seals the upper opening of the air cleaner W, and a door (not shown) is closed to make the upper chamber 2 airtight.

When a vacuum dust collector (not shown) is operated in this state, the strong negative pressure generated in the upper chamber 2 causes the air in the lower chamber 3 to pass through the through hole 12 on the peripheral surface of the cylinder shaft 8 and to the air cleaner W. It invades inside, and from there, each fold of the air filter W spreads out from the inside to the outside, and a large amount of dust adhering to the surface of the filter W in layers is peeled off from this strong flow of air. Then, this is discharged from the upper part of the chamber 2 to the outside by the suction force of the vacuum dust collector.

On the other hand, when the drive motor 10 is started and the turntable 7 is rotated together with this, the air cleaner W placed here starts rotating with the air pipes 25, 25 slidingly contacting each other. In this state, one or both of the valves 29, 30 are opened to introduce pressurized air into the air pipes 25, 25, and the pressurized air is sprayed onto the surface of the air filter W from the air discharge holes 26.

As a result, the dust with a large particle size that is still attached to the surface of the air filter W or the dust that is caught on the surface without being blown off by the air flow from the inside is strong from the air discharge holes 26. It is peeled off by air and removed from the surface of the filter W.

[0019]

[Effect of device]

 As described above, according to the present invention, since the airtight chamber for cleaning the air filter is communicated with the vacuum dust collector, the air cleaner W is equipped with the air cleaner mounting member having the external air introduction portion. When the air cleaner filter is attached or detached, the outside air introduced into the inside of the air cleaner is sucked from the outside by a vacuum dust collector to efficiently separate the dust adhering to the air cleaner W and to discharge it outside the room from the dust collector. It is possible to prevent dust from being scattered around.

Moreover, since the member provided with a large number of air discharge holes is rotated while slidingly contacting the surface of the air cleaner, the dust strongly adhered to the surface can be effectively wiped off by this strong air jet. Thus, this kind of filter can be cleaned efficiently.
