Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an air cleaner installed in industrial vehicles and the like.

BACKGROUND OF THE INVENTION Regarding the above, for example, the Nirasan forklift parts catalog Model FOa series shows the structure shown in FIGS. 6 to 8. That is, main body case 1
After storing the dust removal element 3 inside, attach the end plate 5 to one end of the element 3, and use the cicada screw 7 to attach the end plate 5 to the weld bolt 1b protruding from the support plate 1a inside the main case 1. Tighten and fix. Further, remove the dust cover 9 from the outside of the end plate 5.
Cover with the dust pan 11 and tighten and fix the dust cover 9 and the dust pan 11 to the main body case 1 using a fastener 15 such as a screw band in the presence of the seal member 13.

17.17 is a support bracket for attaching the main body case 1 to a vehicle body side member, 19 is an air intake port, and 21 is an air discharge port.

According to this configuration of the air cleaner, when cleaning the dust removal element 3, the fastener 15 is loosened and the dust cover 9 is removed.
After removing the and dust pan 11 from the main case 1,
By removing the wing screw 7 from the weld bolt 1b, the element 3 can be taken out of the main case 1.
Dust adhering to the element 3 can be cleaned using a brush (not shown) or the like.

Problems to be Solved by the Invention However, in such a conventional air cleaner, two parts, the dust cover 9 and the dust pan 11, must be attached to the outside of the end plate 5. In addition to the problem of increased assembly man-hours and increased cost, there is also the problem that the operation when cleaning the element 3 is cumbersome.

Furthermore, if the dust cover 9 and dust pan 11 are attached without the tightening force of the thumbscrews 7 that tighten and fix the end plate 5 to the weld bolts 1b being insufficient, this condition can be determined from the outside. Therefore, a portion of the air may escape from the air intake port 19 to the air exhaust port 21 without passing through the element 3, which may cause malfunction of the engine.

In order to deal with the above problem, for example, as shown in FIG. 9, the dust cover 9 and the dust pan 11 are integrally connected and fixed at the connecting portions 23 and 23 to form a so-called double lid structure, and the dust cover 9 A configuration in which a dust discharge hole 25 is opened at one end is also known.

According to such a configuration, dust is removed from the dust discharge hole 25.
During cleaning, the dust enters the dust pan 11 side from the main body case 1 and is stored in the dust cover 9 and dust pan 1.
1 can be removed at the same time and the dust can be discarded from the discharge hole 25, which improves operability. Dust and fibers stick to the inside of the double lid and are difficult to dispose of through the discharge hole 25. Therefore, these dusts must be removed manually using tweezers, etc. The problem is that it cannot be said that the sex is good.

Furthermore, as another means for improving work efficiency during cleaning, as shown in FIG. 10, a dust cover 9 and a dust pan 11
are integrally connected and fixed at connecting portions 23 and 23, and a dust discharge hole 25 is opened at one end of the dust cover 9, and
A structure is known in which a dust exhaust hole 27 is also opened in the lower part of the dust pan 11, and a valve body 29 is attached to the dust exhaust hole 27, which opens and closes depending on the pulsation of air taken into the engine.

According to such a configuration, dust flows from the dust discharge hole 25 to the dust discharge hole 27 and the valve body 29 as the air pulsates.
Since the air cleaner is automatically released to the outside through the
The automatically ejected dust covers other parts in the engine room.

For example, it has the disadvantage that it adheres to electrical components such as alternators and starters, as well as fuel tanks, oil tank inlets, suction type radiators, etc., and adversely affects the functions of these components. In order to solve this problem, it is necessary to take measures such as guiding the automatically discharged dust to another duct or releasing it outside the vehicle using a hose, which not only complicates the structure, but also There are problems in that extra costs are incurred as material costs, and the types of vehicles to which this method can be applied are limited.

Therefore, the present invention solves the problems that conventional air cleaners have, and provides an air cleaner that can reduce the number of parts, reduce the number of assembly steps, and simplify the operation when cleaning the elements. The purpose is to provide

Means for Solving the Problems In order to achieve the above objects, the present invention includes a dust removal element housed in a main body case, an end plate fixed to one end of the element, and a dust removal element housed in a main body case, an end plate fixed to one end of the element, and a In the air cleaner comprising a dust pan that is tightened and fixed in the presence of a sealing member, an extension part that is expanded in the radial direction of the end plate is formed at the peripheral edge of the end plate, and the extension part is placed at an appropriate position on the extension part. The air cleaner has a structure in which the dust exhaust flame is opened and the extension part and the peripheral edge of the dust pan are fastened and fixed to the main body case by a fastener.

According to the configuration of the air cleaner, dust that has entered the main body case from the air intake port enters the dust pan side through the dust discharge hole opened in the extension of the end plate and is stored there. Therefore, when cleaning the air cleaner, all you have to do is loosen the fasteners, remove only the dust pan from the main body case, and dispose of the dust stored in the dust pan, making cleaning the air cleaner extremely easy. It has the effect of becoming.

Furthermore, according to this embodiment, since the end plate also serves as a dust cover, it is possible to eliminate the conventionally required dust cover, and the number of parts can be reduced.

Additionally, if the tightening force is insufficient when storing the element in the main body case, a gap will occur between the end of the main body case, the extension of the end plate, and the end of the dust pan. The dust pan cannot be tightened and fixed to the main body case using the fastener. Therefore, the operator can sense that the tightening force of the element inside the main body case is insufficient, and by immediately increasing the amount of pressure, it is possible to attach the dust pan to the main body case in a normal state. Become.

EXAMPLE Hereinafter, an example of the air cleaner according to the present invention will be described in detail, with the same reference numerals attached to the same components as those of the conventional structure.

In the configuration shown in FIGS. 1 to 3, 1 is a main body case, and 3 is a dust removal element housed in the main body case 1. In the structure shown in FIGS. Reference numeral 5 denotes a substantially annular end plate attached to one end of the element 3, and a through hole 2C for a thumb screw 7 is opened at the center of the end plate 5. An extension portion 5a is formed by enlarging the end plate 5 in the radial direction. A dust discharge hole 5b is opened at an appropriate position in this extension portion 5a.

A thumbscrew 7 inserted into the insertion hole 2c of the end plate 5 is tightened and fixed to a weld bolt 1b protruding from a support plate 1a inside the main case 1.

Reference numeral 11 denotes a dust pan, and the dust pan 11 is placed over the end plate 5 from the outside, and in the presence of the seal member 13, the extension portion 5a of the end plate 5 and the peripheral edge 11a of the dust pan 11 are tightened by a fastener 15 such as a screw band. are fastened to the main body case 1.

Therefore, this embodiment is characterized in that the conventionally used dust cover 9 (see FIGS. 6 and 8) is omitted, and the end plate 5 has the function of the dust cover. There is.

According to this configuration of the air cleaner, dust that has entered the main body case 1 from the air intake port is removed from the end plate 5.
The dust enters the dust pan 11 side through the dust discharge hole 5b opened in the extension part 5a of the dust pan 11, and is stored there.

Therefore, when cleaning the air cleaner, all you have to do is loosen the fasteners 15, remove only the dust pan 11 from the main body case l, and dispose of the dust stored in the dust pan 11. This has the effect of making it extremely simple.

On the other hand, if the tightening force of the thumbscrew 7 is insufficient when storing the element 3 in the main body case 1, as shown in FIG. Since a gap α is created between the part 11a and the part 11a, in this state, the dust pan 1 is
1 cannot be tightened and fixed to the main body case 1 together with the end plate 5. Therefore, the operator must
was able to sense that the tightening force of the thumbscrew 7 screwed into the weld nut 1b was insufficient, and by immediately increasing the tightening force of the thumbscrew 7, as shown in FIG. The dust pan 11 can be attached to the main body case 1 in a normal state.

Therefore, there is no risk that a part of the air will escape from the air intake port to the air exhaust port without passing through the element 3 due to insufficient tightening force of the thumbscrew 7, causing malfunction of the engine. is obtained.

Effects of the Invention As described above in detail, the air cleaner according to the present invention provides the following effects.

In other words, since the end plate also serves as a dust cover, it is possible to eliminate the conventionally required dust cover, reduce the number of parts, reduce assembly man-hours, and reduce costs. .

In addition, dust that has entered the main body case from the air intake port enters the dust pan through the dust exhaust hole opened in the extension of the end plate and is stored there, so when cleaning the air cleaner, loosen the fasteners. Since all that is required is to remove the dust pan from the main body case and dispose of the dust stored in the dust pan, cleaning the air cleaner becomes extremely simple. Furthermore, even if the air cleaner is installed in the engine room of a vehicle, dust will not be scattered inside the engine room, so it will not be able to clean other electrical components, fuel tanks, oil tank inlets, suction type radiators, etc. will not adversely affect the functionality of the

Furthermore, if the tightening force is insufficient when storing the element in the main body case, a gap will be created between the end of the main body case, the extension of the end plate, and the end of the dust pan, making it difficult to tighten the element. Since the dust pan cannot be tightened and fixed to the main body case by the tool, the operator can perceive that the tightening force of the elements in the main body case is insufficient.

Therefore, by immediately increasing the supply of the element, it becomes possible to install the dust pan in the main body case in a normal state, and the engine engine will be able to prevent a portion of the air from passing from the air intake port to the air exhaust port without passing through the element. This has the great effect that there is no risk of inducing malfunction.
