Abstract

A grease filter, which includes a first channel having an inlet portion through which oil particles flow in, and a first guide unit configured to guide the oil particles flowing in through the inlet portion, and a second channel having an outlet portion through which the oil particles and air current flowing in through the inlet portion is discharged into the outside, and at least one second guide unit configured to guide the oil particles and air current to be discharged through the outlet portion. Here, the first channel and the second channel are detachably provided. The grease filter can be easily repaired and maintained, and collection efficiency can be improved due to such a configuration.

First claim

What is claimed is:

1. A grease filter comprising:
a first baffle plate including a plurality of inlet portions through which an air flows in and a plurality of first guide members by which the air flowing through the plurality of inlet portions is guided towards a second baffle plate, and
the second baffle plate arranged to face the first baffle plate, the second baffle plate including a plurality of outlet portions through which the air flows out and a plurality of second guide members by which the air flowing out through the plurality of outlet portions is guided,
wherein the second baffle plate is separable from the first baffle plate in entirety by slidably moving only in a horizontal direction with respect to the first baffle plate.

2. The grease filter of claim 1 , wherein the first baffle plate and the second baffle plate are formed so that the first baffle plate and the second baffle plate are at least partially separated from each other.

3. The grease filter of claim 1 , wherein each of the first baffle plate and the second baffle plate comprises a stopper to prevent the first baffle plate and the second baffle plate from being separated beyond predetermined bounds.

4. The grease filter of claim 1 , wherein the first baffle plate coupled to the second baffle plate moves within a guide gap that is a gap between one of the plurality of first guide members and another first guide member adjacent to the one of the plurality of first guide members, and then is separable in a direction opposite to a facing direction of the second baffle plate with respect to the guide gap.

5. The grease filter of claim 1 , wherein the plurality of first guide members and the plurality of second guide members are provided in S-letter shapes, respectively.

6. The grease filter of claim 1 , wherein each of the first baffle plate and the second baffle plate is formed by press processing.

7. The grease filter of claim 1 , wherein the first baffle plate and the second baffle plate are formed of a metal material.

8. The grease filter of claim 1 , wherein the plurality of first guide members and the plurality of second guide members are alternately arranged.

9. The grease filter of claim 8 , wherein the plurality of first guide members and the plurality of second guide members are arranged in plural numbers to be spaced apart at predetermined intervals.

10. The grease filter of claim 1 , wherein:
each of the plurality of first guide members comprises
an inlet guide inclined obliquely toward the second baffle plate; and
a first direction change guide curved from the inlet guide, and

each of the plurality of second guide members comprises
an outlet guide inclined obliquely toward the first baffle plate; and

a second direction change guide curved from the outlet guide.

11. The grease filter of claim 10 , wherein the first direction change guide and the second direction change guide are formed spaced apart to face each other.

12. The grease filter of claim 10 , wherein:
the first baffle plate and the second baffle plate further comprise a first frame and a second frame, respectively, the first frame and the second frame being in a case shape, and the plurality of first guide members and the plurality of second guide members are fixed in the first frame and the second frame, respectively,
the plurality of first guide members comprises a first support member formed to extend from the inlet guide and fixed in the first frame, and
the plurality of second guide members comprises a second support member formed to extend from the outlet guide and fixed in the second frame.

13. The grease filter of claim 12 , wherein:
the first support member is provided to form an obtuse angle with a first inlet plane that is one surface of the inlet guide, and
the first direction change guide is provided to form an obtuse angle with a second inlet plane that is the other surface of the first inlet plane.

14. The grease filter of claim 12 , wherein:
the second support member is provided to form an obtuse angle with a first outlet surface of the outlet guide, and
the second direction change guide is provided to form an obtuse angle with a second outlet surface that is a surface opposite to the first outlet surface.

15. The grease filter of claim 12 , wherein:
the first baffle plate and the second baffle plate are among a plurality of first baffle plates and a plurality of second baffle plates, respectively,
the plurality of first baffle plates are provided to overlap so that a first support member of one of the plurality of first baffle plates is arranged on an inlet portion of another of the plurality of first baffle plates, and
the plurality of second baffle plates are provided to overlap so that a second support member of one of the plurality of second baffle plates is arranged on an outlet portion of another of the plurality of second baffle plates.

16. The grease filter of claim 10 , further comprising a path formed by the first baffle plate and the second baffle plate,
wherein the path comprises
a direction change path spanning between the first direction change guide and the second direction change guide; and
a guide path bypassing the first direction change guide and the second direction change guide and formed between the inlet guide and the outlet guide.

17. The grease filter of claim 16 , wherein the direction change path is formed so that the direction change path has a longer course than the guide path.

18. The grease filter of claim 16 , wherein each of the first baffle plate and the second baffle plate comprises:
a filtering mode operated to enable flow of an air current through the direction change path and the guide path; and
a ventilation mode operated to allow the first direction change guide and the second direction change guide to closely adhere to each other so as to close the direction change path.

19. The grease filter of claim 18 , wherein each of the first baffle plate and the second baffle plate further comprises a release mode operated to allow the inlet guide and the outlet guide to closely adhere to each other so that the first baffle plate and the second baffle plate are spaced apart in a facing direction.

20. A grease filter comprising:
a first baffle plate formed by press processing and including a plurality of inlet portions through which an air flows in, and a plurality of first guide members by which the air flowing through the plurality of inlet portions is guided towards a second baffle plate, and
the second baffle plate formed by press processing and arranged to face the first baffle plate, the second baffle plate including a plurality of outlet portions through which the air flows out and a plurality of second guide members by which the air flowing out through the plurality of outlet portions is guided,
wherein the second baffle plate is separable from the first baffle plate in entirety by slidably moving only in a horizontal direction with respect to the first baffle plate.

21. The grease filter of claim 20 , wherein the plurality of first guide members of the first baffle plate are arranged side by side with the plurality of second guide members of the second baffle plate.

22. The grease filter of claim 20 , wherein:
the first baffle plate is among a plurality of first baffle plates stacked with each other,
the second baffle plate is among a plurality of second baffle plates configured to face the plurality of first baffle plates and stacked w
