Description
- The disclosure of Japanese Patent Application Nos. 2000-033685 filed on Feb. 10, 2000 and 2000-389148 filed on Dec. 21, 2000, including the specifications, drawings and abstracts are incorporated herein by reference in their entirety.
- 1. Field of the Invention
- The invention relates to an air cleaner having a function of absorbing fuel vapor leaking from an intake system of an internal combustion engine.
- 2. Description of the Related Art
- As an air cleaner of the aforementioned kind, an art disclosed in, for example, Japanese Utility Model Application Laid-Open No. SHO 61-58676, is known. In this related art, an air cleaner element and an adsorption filter for absorbing fuel vapor are disposed in an air cleaner housing. Although the laid-open application does not clearly teach a structure for mounting and retaining the adsorption filter to an inner wall of the housing, it can easily be understood that the adsorption filter and the element are separately mounted to the inner wall of the housing. Based on this structure, it is conceivable that a means, such as firm fitting, welding or the like, is employed for mounting the adsorption filter to the housing inner wall.
- Since the adsorption filter and the element are separately mounted to the housing as mentioned above, the workability is not good. Furthermore, if the adsorption filter mounting means is a fitting means, a predetermined fitting clearance is naturally needed, so that the adsorption filter, after being mounted, may suffer rattling, which is a factor of noise. If the mounting means is a welding means, the rattling of the adsorption filter is eliminated, but the mounting operation becomes complicated. Furthermore, regardless of which one of a firm fitting means or a welding means is employed, it is difficult to separate the adsorption filter from the housing for the recycling of the air cleaner, or the like.
- Accordingly, it is an object of the invention to improve workability by making it possible to mount two members, that is, an air cleaner element and an absorber member for absorbing fuel vapor, in a due state merely by mounting the air cleaner element within a housing of an air cleaner, and to simplify the mounting of the absorber member without allowing the rattling thereof, and to relatively facilitate the separation of the absorber member from the housing through the use of a tool or the like for the recycling of the air cleaner, or the like.
- A first aspect of the invention is an air cleaner wherein an element for filtering intake air and an absorber member for absorbing fuel vapor are mounted. Within the housing, a stopper portion for tentatively attaching the absorber member and a seat portion capable of receiving the absorber member at a side opposite from the stopper portion are formed near a site where the element is mounted. The element or the absorber member has a presser portion that retains the absorber member in a state where the absorber member is pressed against the seat portion, when the element is mounted within the housing.
- According to this construction, by tentatively attaching the fuel vapor absorber member within the housing through the use of the stopper portion and by, while maintaining the state, mounting the element to the housing, it is possible to mount the two members, that is, the element and the absorber member, in a due state. Therefore, the workability in mounting the two members improves. Furthermore, although the mounting of the absorber member is a simple operation of tentatively attaching the absorber member as mentioned above, the absorber member is retained in a state that allows no rattling after the mounting thereof is completed. For the recycling of the air cleaner or the like, the housing and the absorber member can be relatively easily separated from each other by using a tool or the like after the element is detached from the housing.
- In the above-described aspect, the stopper portion may have a protruded shape having a size that allows the stopper portion to retain an outer peripheral portion of the absorber member to an inner wall of the housing to such a degree that the outer peripheral portion does not fall apart from the housing, and the seat portion may be an end portion of a rib extending on an inner wall of the housing substantially in a direction of a flow of the intake air.
- Therefore, neither the stopper portion nor the seat portion increases the resistance against the flow of intake air within the housing. Hence, regardless of whether the absorber member is used, the housing and the like can be commonly used without degradations in the intake resistance characteristic and the filtering capability of the air cleaner.
- Furthermore, in the above-described aspect, the presser portion of the absorber member or the element may have a rigidity corresponding to the seat portion of the housing.
- Therefore, after the element is mounted, the absorber member is firmly secured by the seat portion and the presser portion, and the secured state is stable.
- The foregoing and further objects, features and advantages of the invention will become apparent from the following description of preferred embodiments with reference to the accompanying drawings, wherein like numerals are used to represent like elements and wherein:
- FIG. 1 is a sectional view of an air cleaner in accordance with a first embodiment of the invention, in a disassembled state;
- FIG. 2 is a sectional view of the air cleaner, illustrating an assembled state thereof;
- FIG. 3 is an enlarged sectional view of a portion of the air cleaner enclosed in an imaginary-line circle in FIG. 2;
- FIG. 4 is an enlarged sectional view of a portion of a housing according to a modification of the first embodiment, corresponding to the view of FIG. 3;
- FIG. 5 is a sectional view of an air cleaner in accordance with a second embodiment of the invention; and
- FIG. 6 is an enlarged sectional view of a portion of an air cleaner in accordance with a third embodiment of the invention, corresponding to the view of FIG. 3.
- Preferred embodiments of the invention will be described below.
- A first embodiment will be described with reference to FIGS.1 to 3. FIG. 1 is a sectional view of an air cleaner of an internal combustion engine, in a disassembled state. FIG. 2 is a sectional view of the air cleaner illustrating an assembled state thereof. FIG. 3 is an enlarged sectional view of a portion enclosed in an imaginary-line circle in FIG. 2. As show in these drawings, a
housing 10 of the air cleaner is a molding formed from a synthetic resin. Thehousing 10 is divided into alower housing 10 a having aninlet port 12, and anupper housing 10 b having anoutlet port 14. Therefore, an upper face of thelower housing 10 a and a lower face of theupper housing 10 b are open. Thehousing 10 is designed so that an outerperipheral frame 32 of an air cleaner element 30 (described below) is clamped and secured between opening edges of thelower housing 10 a and theupper housing 10 b. -
Clamps 18, each formed by a metal spring member, are attached tobrackets 16 that are formed together with an outer peripheral portion of thelower housing 10 a. Thebrackets 16 and theclamps 18 are disposed at several positions in a circumferential direction along the periphery of thelower housing 10 a. Aclamp receptacle 20 continuously extends in a circumferential direction on an outer periphery of the opening portion of theupper housing 10 b. Theclamps 18 can be engaged with and retained to theclamp receptacle 20. - As is apparent from FIG. 3, a protrusion-
like stopper portion 22 is slightly protruded inward from an inner wall of theupper housing 10 b, at a site near the opening thereof. Thestopper portion 22 is provided for tentatively attaching and retaining a fuelvapor absorber member 28, and has an arc-like sectional shape. A shape of thestopper portion 22 with respect to the circumferential direction of theupper housing 10 b may be either one of a continuous shape extending over the entire range and a discontinuous shape fragmented at predetermined intervals. - A plurality of
ribs 24 are formed on the inner wall of theupper housing 10 b, and extend inwardly of thestopper portion 22 of the opening portion. Eachrib 24 extends along the direction of flow of intake air (indicated by arrows in FIG. 2) within theupper housing 10 b. An opening-side end portion of eachrib 24 forms aseat portion 26 that receives theabsorber member 28 when theabsorber member 28 is mounted in a due manner. - The
absorber member 28 is a member for absorbing fuel vapor leaking from the side of the outlet port 14 (the engine side) and thereby preventing emission of fuel vapor to outside the vehicle. Theabsorber member 28 is disposed upstream or downstream of theair cleaner element 30 for filtering external air. Theabsorber member 28 is tentatively attached inside theupper housing 10 b by insetting it inwardly of thestopper portion 22 from the opening portion of theupper housing 10 b (FIG. 1) before joining thelower housing 10 a and theupper housing 10 b. Therefore, thestopper portion 22 will suffice if thestopper portion 22 has a shape that facilitates the insetting of the absorber member 28 (for example, an arcuate shape in section), and has such a small amount of protrusion that theabsorber member 28 will not from falling apart. - The
stopper portion 22 may be replaced by astopper portion 52 having a right triangular shape in section, which is provided with atilt surface 52 f and a shelf-like portion 52 t as shown in FIG. 4. When inserting theabsorber member 28 to the inside of thestopper portion 52 from the opening portion of theupper housing 10 b, the peripheral edge of theabsorber member 28 fits along thetilt surface 52 f of thestopper portion 52. This makes it possible to tentatively attach theabsorber member 28 between thestopper portion 52 and theseat portion 26 with ease. The tentatively attachedabsorber member 28 can be supported reliably by the shelf-like portion 52 t of thestopper portion 52. - The shape of the
stopper portion 52 with respect to the peripheral direction of theupper housing 10 b may be continually formed or separately formed at a predetermined interval over the entire length. However, it is preferable to be separately formed at a predetermined interval such that theabsorber member 28 can be easily removed in a recycling process. - When the
absorber member 28 is tentatively attached, a fitting clearance (not shown) of a normally needed size is secured between theabsorber member 28 and theseat portions 26. - Typically, a non-woven cloth is used in the
air cleaner element 30, and a hard outerperipheral frame 32 formed by, for example, injection molding of a synthetic resin, is provided around an outer peripheral portion of the non-woven cloth. The outerperipheral frame 32 has aseal 36 in a portion of theframe 32 that is clamped between the opening edges of thelower housing 10 a and theupper housing 10 b, as is apparent in FIG. 3. The outerperipheral frame 32 has apresser portion 34 that extends beyond thestopper portion 22 and presses theabsorber member 28 against theseat portions 26 when theair cleaner element 30 is mounted within thehousing 10. Thepresser portion 34 may be formed by hardening an end portion of the non-woven cloth through pressing. An important point herein is that thepresser portion 34 be provided with a rigidity that matches the rigidity of theseat portions 26. - In the air cleaner constructed as described above, the
absorber member 28 is tentatively attached inside theupper housing 10 b by insetting theabsorber member 28 inwardly of thestopper portion 22 in the above-described manner. Next, thelower housing 10 a and theupper housing 10 b are joined with theseal 36 of the outerperipheral frame 32 of theair cleaner element 30 being positioned between the opening edges of the twohousings clamps 18 to theclamp receptacle 20. In this manner, theair cleaner element 30 is mounted within thehousing 10 and, at the same time, thepresser portion 34, extending beyond thestopper portion 22, presses the outer peripheral portion of theabsorber member 28 against theseat portions 26. Therefore, the mounting of theabsorber member 28 to the interior of thehousing 10 is also completed. - That is, by mounting the
air cleaner element 30 to thehousing 10, the two members, that is, theair cleaner element 30 and theabsorber member 28, are mounted in the due state. Thus, the workability in mounting the two members improves. After being mounted, theabsorber member 28 is pressed against theseat portions 26, while filling the aforementioned fitting clearance. Therefore, the rattling of theabsorber member 28, which becomes a cause for noises or vibrations of the air cleaner, is resolved. For the recycling of the air cleaner or the like, theabsorber member 28 can be relatively easily separated from theupper housing 10 b by using a tool or the like after separating thelower housing 10 a and theupper housing 10 b from each other and detaching theair cleaner element 30. - As described above, the
stopper portion 22 has an amount of protrusion that is small but sufficient to prevent theabsorber member 28 from falling apart when theabsorber member 28 is tentatively attached to theupper housing 10 b. Theribs 24 forming theseat portions 26 extend following the direction of flow of intake air. Therefore, the presence of thestopper portion 22 and theribs 24 does not increase the resistance against the flow of intake air within thehousing 10. Hence, thehousing 10 can also be applied to an air cleaner that does not employ anabsorber member 28, without degrading the intake air resistance characteristic nor the filtering capability. - It should be noted herein that a conventional absorber member mounting means employing welding also has problems of degradations in the intake resistance characteristic and the filtering capability of the air cleaner because the conventional means needs relatively large welding seats within the housing and therefore sacrifices the capacity within the housing.
- A second embodiment of the invention will be described with reference to FIG. 5. FIG. 5 is a sectional view of an air cleaner, illustrating a state where an air
cleaner element 30 is mounted to ahousing 10. Thehousing 10 of the second embodiment is of an integral structure type, in which a portion of a side wall of thehousing 10 has anopening 40 for inserting theabsorber member 28 and theair cleaner element 30. Firstly, theabsorber member 28 is disposed within thehousing 10 by inserting theabsorber member 28 through theopening 40. Using astopper portion 22 formed on an inner wall of thehousing 10, theabsorber member 28 is tentatively attached inside thehousing 10 as in the first embodiment. - An outer
peripheral frame 32 of theair cleaner element 30 has apresser portion 34 as in the first embodiment. Furthermore, the outerperipheral frame 32 has acover portion 44 for closing theopening 40 from outside, and ahinge 42 that is disposed opposite from thecover portion 44. To mount theair cleaner element 30, theair cleaner element 30 is disposed and set in thehousing 10 via theopening 40, starting at a side of thehinge 42. After that, thehinge 42 is positioned to arecess 11 formed in the inner wall of thehousing 10. While this state is maintained, theair cleaner element 30 is turned about thehinge 42 in a direction indicated by an arrow in FIG. 5, so that thecover portion 44 closes theopening 40. The thus-established state is maintained by aclaw 46 formed on thecover portion 44 being engaged with aclaw receptacle 48 formed on an outer wall of thehousing 10. - Thus, the mounting of the
air cleaner element 30 into thehousing 10 is completed, and thehousing 10 is tightly closed. At the same time, thepresser portion 34, extending beyond thestopper portion 22, presses the outer peripheral portion of theabsorber member 28 against theseat portions 26. Thus, theabsorber member 28 is mounted within thehousing 10 in a due state. Therefore, according to the second embodiment, too, by mounting theair cleaner element 30 to thehousing 10, the two members, that is, theair cleaner element 30 and theabsorber member 28, are mounted in a due state. Thus, the second embodiment achieves substantially the same functions and advantages as mentioned above. Portions of the second embodiment are substantially the same as those of the first embodiment, except the type of thehousing 10 and the means for mounting theair cleaner element 30 to an interior of thehousing 10. Therefore, description of those portions is omitted. - A third embodiment will next be described with reference to FIG. 6. FIG. 6 is an enlarged sectional view of a portion of an air cleaner, corresponding to the view of a portion of the first embodiment in FIG. 3. As is apparent in FIG. 6, a
presser portion 29 is formed on anabsorber member 28 in the third embodiment, instead of thepresser portion 34 of theair cleaner element 30. When theabsorber member 28 is tentatively attached within aupper housing 10 b, to a site located inwardly of astopper portion 22, thepresser portion 29 extends beyond thestopper portion 22 and reaches the vicinity of an opening of theupper housing 10 b. - When the
air cleaner element 30 is mounted within thehousing 10 in a manner as described above in conjunction with the fist or second embodiment, the outerperipheral frame 32 of theair cleaner element 30 contacts an end surface of thepresser portion 29, so that, via thepresser portion 29, an outer peripheral portion of theabsorber member 28 is pressed against theseat portions 26. This state is retained. Therefore, in this embodiment, too, by mounting theair cleaner element 30 to thehousing 10, the mounting of theabsorber member 28 is also completed as in the first and second embodiments. Thispresser portion 29 is also provided with a rigidity that matches the rigidity of theseat portions 26, by hardening thepresser portion 29 through pressing or a different process. - Although in the first, second and third embodiments, the
absorber member 28 is disposed downstream of theair cleaner element 30, that is, at the outlet port 14-side within thehousing 10, it is also possible to adopt a construction in which theabsorber member 28 is disposed upstream of theair cleaner element 30. - While the invention has been described with reference to what are presently considered to be preferred embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments or constructions. On the contrary, the invention is intended to cover various modifications and equivalent arrangements.
