Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air cleaner device that is installed at the inlet of an intake system of an internal combustion engine and is capable of cleaning the atmosphere introduced into the intake system.

Generally, in the air cleaner device, a cleaner element unit is removably installed in an air flow passage within an air cleaner case. However, in conventional air cleaner element units, the holder that holds the cleaner element is attached to the cleaner element using multiple mounting screws and other fittings, which not only takes time and effort to assemble, but also has the disadvantage of increasing costs due to the large number of parts. Ta.

The present invention can solve the above-mentioned problems, and also makes it possible to clamp and fix the cleaner element extremely firmly in a predetermined position between a pair of holders.
The purpose is to provide an air cleaner device with a simple structure.

In order to achieve the above object, the present invention provides an air cleaner case that opens an inlet and an outlet and forms an air flow passage that communicates them, and that can be installed and removed in the air flow passage across the passage. An air cleaner device comprising a freely attachable cleaner element unit, wherein unpurified air flowing into the air flow passage from the inlet is purified through the cleaner element unit and then discharged from the outlet. The unit consists of a plate-shaped cleaner element and a pair of first and second holders made of synthetic resin that are respectively polymerized on both the front and back surfaces of the cleaner element, and the first and second holders are formed of a lattice-shaped frame. and a connecting male piece is integrally provided on the bone member of one of the holders, and a connecting male piece that is removably fitted to the connecting male piece is provided on the bone member of the other holder. Furthermore, a rib protruding toward the cleaner element is integrally formed on the contact surface of the bone member of each holder with the cleaner element.

An embodiment of the present invention will be described below with reference to the drawings.

An inlet 2 is opened on one side of the air cleaner case 1, and an inflow pipe 3 curved in an elbow shape is connected to the inlet 2, and an outlet 4 is opened on the other side of the air cleaner case 1, and the inlet 2 is connected to the inlet 2. A flexible outflow pipe 5 is connected to the outlet 4. An air flow passage 6 is formed in the air cleaner case 1 to communicate the inlet 2 and the outlet 4, and a cleaner element unit Uc is provided in the middle of the air flow passage 6.
is removably attached, and this unit Uc divides the airflow passage 6 into an uncleaned chamber a on the inlet 2 side and a clean chamber b on the outlet 4 side.

As shown in FIGS. 1 and 3, upper and lower guide rails 7 and 8 are formed on the upper and lower walls of the airflow passage 6 to cross the airflow passageway 6 and are opposed to each other. , one end of the lower guide rails 7, 8 faces an entrance/exit 9 opened in the side wall of the air cleaner case 1. The cleaner element unit Uc can be inserted into the air cleaner case 1 from the entrance/exit 9 along the upper and lower guide rails 7 and 8. Supported within 1. The lid 1 is attached to the entrance/exit 9 with screws 10.
1 is deposited.

The cleaner element unit Uc is composed of a plate-shaped cleaner element 12 and a pair of synthetic resin first and second holders 13 and 14 that are polymerized and fixed to both the front and back sides of the cleaner element 12.

The cleaner element 12 is provided with several mounting holes 15, and the first holder 13 is provided with several mounting holes 15.
is formed from a lattice-like frame body, and the bone members 16 are
A rib 17 protruding toward the element 12 is integrally formed on the contact surface with the cleaner element 12. In addition, in a part of the joints between the bone members 16,
Several connecting male pieces 18 are integrally provided in correspondence with the mounting holes 15 of the cleaner element 12. As shown in FIG. 4, the connecting male piece 18 is provided with several locking pieces 18 ₁ .
₁ has elasticity in the radial direction, and a retaining piece ₁₈₂ is integrally formed at its tip.

Furthermore, the second holder 14 is formed of a lattice-shaped frame like the first holder 13, and a rib 17 that protrudes toward the element 12 is integrally formed on the contact surface of the bone member 16 with the cleaner element 12. The mounting hole 1 of the cleaner element 12 is formed in a part of the interconnection portion of the bone members 16.
5 and the connecting male pieces 18 of the first holder 13, several connecting male and female pieces 19 are integrally formed. As shown in FIG. 4, this connecting male piece 19 has a fitting hole 19 in the center of the short cylindrical portion into which the connecting male piece 18 can be fitted.
₁ is formed. A table of cleaner element 12,
Polymerize the first and second holders 13 and 14 on both back surfaces,
The several connecting male pieces 18 are connected to the cleaner element 1.
After inserting it into the mounting hole 15 of 2, the connecting female piece 19
When the first and second holders 13 and 14 are fitted into the fitting hole ₁₉₁ and the retaining piece ₁₈₂ is engaged with the periphery of the fitting hole ₁₉₁ , the first and second holders 13 and 14 are joined together with the cleaner element 12 in between. . Since the connecting male piece 18 has several locking pieces 18 ₁ ... that can expand and contract in the radial direction,
The above-mentioned connection is performed smoothly, and after the connection, the retaining piece 1
_{The first} ,
The second holders 13 and 14 will not separate accidentally.

The cleaner element unit Uc assembled as described above is assembled in the middle of the air flow passage 6 of the cleaner case 1 as described above.

The air cleaner device is used, for example, by connecting its outflow pipe 5 to the outer end of the intake system of an internal combustion engine, and when negative intake pressure is generated in the intake system due to operation of the internal combustion engine, Atmospheric air flows into the air flow passage 6 through the inflow pipe 3, passes through the cleaner element unit Uc and is purified, and then is guided through the outflow pipe 5 into the intake system.

As is clear from the above embodiments, according to the present invention, the air flow passage 6 in the air cleaner case 1
The cleaner element unit Uc provided in the cleaner element unit Uc includes a plate-shaped cleaner element 12 and a pair of first and second holders 13 and 14 made of synthetic resin, which are respectively superposed on the front and back surfaces of the cleaner element 12. 1, the second holders 13 and 14 are formed of lattice-like frames, and the bone member 16 of one holder 13 has a connecting male piece 18, and the bone member 16 of the other holder 14 has the connecting male piece 18. Since the connecting female pieces 19 that are removably fitted to the male pieces 18 are each provided integrally, both the holders 13 and 1
4 and the cleaner element 12 can be easily and quickly assembled without using special tools such as screws or other fittings, and each holder 13, 14 in a grid shape can be assembled easily and quickly.
Even if it is polymerized on both the front and back surfaces of the cleaner element 12, it does not impede the smooth flow of air passing through the element 12 in any way.

Furthermore, ribs 17 protruding toward the element 12 are integrally formed on the contact surfaces of the bone members 16 of each holder 13, 14 with the cleaner element 12, so that the bone members 16 of each holder 13, 14 are The ribs 17 significantly increase the rigidity, and the ribs 17 can be strongly bitten into both the front and back sides of the cleaner element 12, which, together with the effect of the male and female pieces 18 and 19 fitting together, is effective. , a cleaner element 1 is placed at a predetermined position between both holders 13 and 14.
2 can be held and fixed extremely firmly, and there is no fear that the cleaner element 12 will flap even when a large pressure change occurs across the cleaner element unit Uc, such as when starting or stopping the engine. Further, the rib 17 is connected to the bone member 16.
The connecting male and female pieces 18,
19 serves both as a connecting means between both holders 13 and 14 and as a reinforcing member for the bone member 16,
The structure is simple and can contribute to cost reduction.
