Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to an integrated stove. Background Art

[0002] Most existing integrated stoves adopt a bottom exhaust structure. When the fan system in the machine body starts working, a large amount of oil smoke is sucked into the machine head flue and passes downward through the fan system, and finally discharged from the air outlet of the machine body. It can be seen that in the process of smoking and exhausting, almost all the oil smoke entering the machine head flue passes through the fan system.

[0066] The specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0067] The integrated stove according to the present invention will be described below with reference to the accompanying drawings.

[0068] like Figures 1 to 21 As shown, an exemplary embodiment of the present invention provides an integrated stove 100, which mainly includes a body 1, a head 2, a front oil fume channel 22 and a pre-filter module.

[0069] Specifically, the body 1 is provided with a stove 11 and an integrated functional part 12 and an oil fume exhaust part located below the stove 11. The integrated functional part 12 and the oil fume exhaust part are usually arranged front and back, and the integrated functional part 12 may include a dishwasher part, a disinfection cabinet part, a storage cabinet part, a steamer part, an oven part or a microwave oven part, etc., so as to diversify the functions of the integrated stove 100. The oil fume exhaust part is provided with a fan system 13 and a body air outlet 14. The body air outlet 14 is used to exhaust the oil fume outside the body 1. The fan system 13 is used to generate wind force for smoking and exhausting smoke. It is usually difficult to clean due to its installation position and installation structure.

[0070] In addition, the machine head 2 is located above the stove 11 and is provided with a channel oil fume inlet 21, and a front oil fume channel 22 is formed between the channel oil fume inlet 21 and the oil fume exhaust part. Figures 1 to 3 The front oil fume channel 22 can be defined by the peripheral wall of the machine head and the smoke baffle 23, so the front oil fume channel 22 includes an inner cavity of the machine head, and a pre-filter module is arranged in the inner cavity of the machine head for separating the oil fume, and the pre-filter module is preferably arranged to be detachably installed in the inner cavity of the machine head.

[0071] It should be noted that the channel oil fume inlet 21 is usually provided with an inlet oil fume filter, and the pre-filter module in this exemplary embodiment is different from the inlet oil fume filter and is a filtering structure located at the subsequent stage of the inlet oil fume filter.

[0072] During the smoke intake and exhaust process of the integrated stove 100, the oil smoke can be discharged outside the fuselage 1 after passing through the channel oil smoke inlet 21, the front oil smoke channel 22 and the oil smoke exhaust part in sequence. Due to the oil smoke separation effect of the pre-filter module, a large amount of oil smoke has been condensed into liquid oil and attached to the pre-filter module before flowing to the oil smoke exhaust part, thereby effectively reducing the degree of contamination of the fan system 13 and thus ensuring its working efficiency and service life.

[0073] In one embodiment, the pre-filter module can be set as a fixed structure. In other words, during the smoking and exhausting process, the pre-filter module always remains fixed, so the pre-filter module should not include movable parts such as rotating parts, telescopic parts, and transmission parts.

[0074] Specifically, the pre-filter module may include a pre-oil filter 24, which may be configured as a fixed filter plate with smoke holes, and the fixed filter plate may be configured as a single-layer filter plate or a multi-layer filter plate, which will be described in detail below.

[0075] Reference Figure 2 as well as Figures 5 to 8The pre-filter 24 is configured as a single-layer filter plate and includes an oil filter body 243a, a plurality of smoke holes, an oil guide groove 243f and an oil filter outlet. The plurality of smoke holes are arranged through the oil filter body 243a and the peripheral wall of each smoke hole is formed with a hole flange 243e. The oil guide groove 243f is formed between the plurality of hole flanges 243e. The oil filter outlet is arranged at the end of the oil filter body 243a and communicates with the oil guide groove 243f.

[0076] By setting the above structure, when the oil smoke passes through the multiple smoke holes in the pre-filter 24, a large amount of oil smoke condenses into liquid oil when it contacts the oil filter body 243a and adheres to the oil guide groove 243f, thereby achieving oil smoke separation to reduce the pollution of the fan system 13. Furthermore, the filtered oil in the oil guide groove 243f can be further diverted to the oil filter outlet, which is convenient for collection and cleaning, thereby improving the user experience. It can be seen that by setting the pre-filter 24 as the above-mentioned single-layer filter plate, the functions of separating oil smoke and diverting and filtering oil can be achieved, and at the same time, it has a simple structure for easy processing, which is conducive to improving production efficiency and reducing costs.

[0077] Reference Figures 9 to 14 The pre-filter 24 is configured as a multi-layer filter plate and includes an oil filter body 243a, which includes a bottom filter unit 243b, a top filter unit 243c and a filter unit connector 243d. The top filter unit 243c and the bottom filter unit 243b are in the shape of long plates and are stacked up and down, and the filter unit connector 243d is used to fix the bottom filter unit 243b and the top filter unit 243c. In addition, the bottom filter unit 243b and the top filter unit 243c are respectively provided with a plurality of smoke holes, and the hole peripheral wall of each smoke hole on the bottom filter unit 243b is formed with a hole flange portion, and the bottom filter unit 243b is also provided with a bottom oil guide groove defined by a plurality of hole flange portions and an oil filter outlet provided at the end of the bottom filter unit 243b and connected to the bottom oil guide groove.

[0078] As can be seen from the above structure, the top filter unit 243c and the bottom filter unit 243b stacked up and down can play a multiple filtering role on the oil smoke, so most of the oil pollution in the oil smoke can be effectively intercepted, thereby greatly reducing the pollution of the oil smoke to the fan system 13. The intercepted filtered oil can flow to the bottom filter unit 243b, and be guided to the oil outlet of the oil filter under the guidance of the bottom oil guide groove, so as to facilitate collection and cleaning, thereby helping to improve the user experience.

[0079] In order to increase the interception area, the top filter unit 243c can be set as a bent plate, and the number of bent sections of the bent plate can be determined based on the actual required interception effect, processing difficulty, production cost, etc. For example, Fig.11 The number of bend sections of the top filter unit 243c in the illustrated embodiment is greater than Fig.14 The number of bent sections of the top filter unit 243c in the illustrated embodiment differs in terms of the interception effect of oil pollution, processing difficulty, production cost, etc. In addition, more than two layers of filter units may be provided in the oil filter body 243a to enhance the multiple filtering effect.

[0080] In one embodiment, the pre-filter module can be configured as a movable structure. Figures 15 to 20 The pre-filter module includes a pre-filter 24, which is configured as a rotating filter that can pivot around its own central axis and is provided with a plurality of smoke holes. When the oil smoke passes through the plurality of smoke holes on the rotating filter, a large amount of oil can be intercepted by the rotating filter due to the continuous rotation of the rotating filter, thereby achieving an oil smoke separation effect.

[0081] In order to realize the self-pivot of the rotating filter element, an oil filter fixing bracket 244e fixedly mounted on the inner wall of the machine head 2 and an oil filter rotating bracket 244f fixedly mounted on the oil filter fixing bracket 244e can be provided in the pre-filter module, and the oil filter rotating bracket 244f is provided with a pivot shaft axially connected to the rotating filter element.

[0082] Referring to the illustrated embodiment, the rotary filter element may include a rotary filter sleeve 244a and a plurality of guide blades 244b located in the sleeve cavity of the rotary filter sleeve 244a, a plurality of smoke holes are formed on the peripheral wall of the rotary filter sleeve 244a, and the plurality of guide blades 244b are circumferentially arranged in sequence and spaced apart on the inner peripheral wall of the rotary filter sleeve 244a and extend along the central axis direction of the rotary filter sleeve 244a.

[0083] Furthermore, the rotary filter element may also include a sleeve fixing bracket 244c fixedly mounted on both axial ends of the rotary filter sleeve 244a and a blade fixing bracket 244d fixedly mounted on the sleeve fixing bracket 244c, and ends of the plurality of guide blades 244b are fixedly connected to the blade fixing bracket 244d.

[0084] Based on the above structure, a driving motor can be provided in the pre-filter module to drive the rotating filter element to rotate. For example, the motor shaft of the driving motor can be connected to the pivot shaft of the oil filter rotating bracket 244f, thereby indirectly driving the rotating filter element to rotate, so that the rotating mode of the rotating filter element can be controlled.

[0085] It should be noted that when the rotation speed of the rotary filter element is too fast, the wind resistance in the front oil fume channel 22 will be too large, thereby affecting normal smoking and exhaust. When the rotation speed is too slow, it cannot achieve a good oil fume separation effect. Therefore, in order to minimize the wind resistance caused by the rotary filter element and maximize the oil fume separation effect, the rated speed of the rotary filter element is preferably set to 60r / min~120r / min. Usually, three speed gears can be set in the integrated stove 100, namely, a low speed gear, a medium speed gear and a high speed gear, wherein the rated speed of the rotary filter element corresponding to the low speed gear is about 60r / min, the rated speed of the rotary filter element corresponding to the medium speed gear is about 90r / min, and the rated speed of the rotary filter element corresponding to the high speed gear is about 110r / min.

[0086] Of course, since a wind field will be formed in the front oil fume passage 22 during the smoking and exhausting process, the rotating filter element can self-pivot under the action of the wind field even if a driving motor is not provided. However, in order to make the self-pivoting more continuous and stable, a windward driving surface for driving the rotating filter element to rotate under the impact of the airflow can be formed in the rotating filter element. In other words, when the fan system 13 starts to work, a wind field will be formed in the front oil fume passage 22, and the airflow in the wind field can continuously hit the windward driving surface, thereby driving the rotating filter element to self-pivot.

[0087] For example, refer to Fig.18 The arrow inside the rotating filter sleeve 244a indicates the direction of airflow, and the arrow outside the rotating filter sleeve 244a indicates the rotation direction of the rotating filter element. At this time, multiple guide blades 244b are formed with windward driving surfaces, and the airflow can continuously impact on the multiple windward driving surfaces to generate a larger rotational driving force, thereby ensuring that the rotating filter element rotates continuously and stably during the smoking and exhausting process.

[0088] In addition, an inner wall oil collecting groove 27 may be provided in the pre-filter module. The inner wall oil collecting groove 27 is installed on the inner wall of the front oil fume channel 22 to at least receive the filtered oil thrown out from the rotating filter element toward the inner wall of the channel (part of the filtered oil thrown out from the rotating filter element may also fall directly into the inner wall oil collecting groove 27), thereby preventing the filtered oil on the inner wall of the channel from flowing downward to the fan system 13.

[0089] Reference Fig.15 and Fig.19 When the rotary filter element is extended left and right, the left and right span of the inner wall oil receiving groove 27 can be set to be no less than the left and right span of the front oil fume channel 22 to ensure that the filtered oil flowing downward along the inner wall of the channel is completely collected.

[0090] In summary, when the oil smoke passes through the pre-filter module with a fixed or movable filter structure at high speed, due to the presence of a large number of eddies in the filter structure, the oil smoke will turn and collide at high speed in the filter structure, causing its own flow path and flow direction to change dramatically. During this rapid change, the oil molecules in the oil smoke will be separated and thrown directly onto the filter structure, and the temperature of the filter structure is much lower than that of the oil molecules, which will cause a large number of oil molecules to quickly condense into liquid oil and adhere to it, thereby greatly reducing the condensation and accumulation of oil molecules in the fan system 13.

[0091] In one embodiment, referring to Figure 2 , Figure 6 , Fig. 9 , Fig.12 , Fig.15 and Fig.16 , the pre-filter module also includes a head oil collection box 25, which can at least be used to collect the filtered oil attached to the pre-filter module, so the head oil collection box 25 is preferably arranged in the front oil fume channel 22 and below the pre-filter module. Under this structure, it is convenient to centrally clean the filtered oil on the pre-filter module, and the head oil collection box 25 can be further set as a detachable structure to facilitate the user to manually remove and clean it. For example, an oil collection box bracket 26 can be fixedly installed on the rear wall of the front oil fume channel 22, and the head oil collection box 25 can be detachably installed on the oil collection box bracket 26 and is set to be able to be taken out forward from the oil collection box bracket 26 to meet the user's usage habits.

[0092] In order to ensure that all the filtered oil in the pre-filter module flows into the head oil collection box 25, an internal oil guide structure for guiding the filtered oil can be formed in the pre-filter module. For example, the internal oil guide structure may include the oil guide groove 243f in the oil filter body 243a, and the head oil collection box 25 can be set directly below the oil filter outlet, so that the filtered oil flows into the head oil collection box 25 through the oil filter outlet under the guiding effect of the oil guide groove 243f.

[0093] In one embodiment, referring to Figures 2 to 18 The pre-filter module includes a pre-filter 24, which is arranged in a V-shape and is provided with an internal oil guide structure for guiding the filtered oil to the bottom of the V-shape, and the pre-filter module also includes a head oil collection box 25 located below the bottom of the V-shape. By arranging the pre-filter 24 in a V-shape, it can be tilted at a certain angle relative to the horizontal plane, so that the filtered oil is always guided to the bottom of the V-shape under the action of the internal oil guide structure and gravity, so that the filtered oil finally flows into the head oil collection box 25, so that it can be cleaned centrally.

[0094] Reference Figures 6 to 8The pre-filter 24 can be provided as an integrally formed part and includes a first filter portion 242a, a transition connection portion 242b and a second filter portion 242c connected in sequence. In addition, the outer end of the first filter portion 242a is inclined upward relative to the inner end of the first filter portion 242a, the outer end of the second filter portion 242c is inclined upward relative to the inner end of the second filter portion 242c, and the transition connection portion 242b is located at the bottom end of the V-shape, so that the pre-filter 24 is arranged in a V-shape as a whole.

[0095] Based on the above-mentioned integrally formed part, the internal oil guide structure may include a first internal oil guide structure disposed in the first oil filter portion 242a and a second internal oil guide structure disposed in the second oil filter portion 242c. In order to make the overall structure uniform and reasonable and simplify processing, the first internal oil guide structure and the second internal oil guide structure may be set to the same structure.

[0096] In addition, an oil collection groove 242d may be formed in the transition connection part 242b, and the first internal oil guide structure and the second internal oil guide structure extend obliquely toward the oil collection groove 242d to guide the respective filtered oil to the oil collection groove 242d. The bottom wall of the oil collection groove 242d may be provided with an oil filter outlet to guide the filtered oil to the head oil collection box 25 below. Of course, in the case where the transition connection part 242b is not formed with the oil collection groove 242d, an oil filter outlet may also be provided. By providing the oil collection groove 242d, the filtered oil needs to accumulate in the groove to a certain volume before it flows out from the oil filter outlet, which is equivalent to increasing the oil collection volume of the pre-filter module, thereby alleviating the oil collection pressure of the head oil collection box 25 to a certain extent.

[0097] When the front oil filter 24 is the above-mentioned single-layer filter plate, the first oil filter portion 242a and the second oil filter portion 242c are both provided with a plurality of smoke holes and a plurality of hole flange portions 243e, the first internal oil guide structure and the second internal oil guide structure both include oil guide grooves 243f formed between the plurality of hole flange portions 243e, and the oil guide grooves 243f in the first internal oil guide structure and the second internal oil guide structure are both connected to the oil outlet of the oil filter.

[0098] Reference Figure 2 , Figure 5 as well as Figures 9 to 20 , the pre-filter 24 can be set as a split structure and include a first filter 241a and a second filter 241b that are independent and tilted. At this time, the outer end of the first filter 241a is tilted upward relative to the inner end of the first filter 241a, the outer end of the second filter 241b is tilted upward relative to the inner end of the second filter 241b, and the inner end of the first filter 241a and the inner end of the second filter 241b together serve as the V-shaped bottom end of the pre-filter 24. Compared with the one-piece structure, the split structure can be disassembled and cleaned independently, so the user experience is better in terms of cleaning and maintenance.

[0099] It should be noted that the first oil filter 241a and the second oil filter 241b can be respectively set as the aforementioned fixed structure or movable structure. When set as a fixed structure, it can be set as the aforementioned single-layer filter plate or multi-layer filter plate. When the first oil filter 241a and the second oil filter 241b are both set as single-layer filter plates or multi-layer filter plates, the inner end of the first oil filter 241a and the inner end of the second oil filter 241b are both provided with oil filter outlets. When set as a movable structure, the first oil filter 241a and the second oil filter 241b can be set as the aforementioned rotating filter.

[0100] Based on the above split structure of the pre-filter 24, its internal oil guide structure may include a first internal oil guide structure disposed in the first oil filter 241a and a second internal oil guide structure disposed in the second oil filter 241b. Similarly, in order to make the overall structure uniform and reasonable and simplify processing, the first internal oil guide structure and the second internal oil guide structure may be set to the same structure.

[0101] In one embodiment, the inclined angle between the V-shaped pre-filter 24 and the horizontal plane can be set to α. For example, corresponding to the above-mentioned integrated structure, α is the acute angle of the first oil filter 242a or the second oil filter 242c relative to the horizontal plane. And corresponding to the above-mentioned split structure, α is the acute angle of the first oil filter 241a or the second oil filter 241b relative to the horizontal plane.

[0102] When α is too small (i.e., the degree of inclination is insufficient), the filtered oil may have difficulty in overcoming the viscous resistance to flow smoothly, resulting in the inability to be guided to the bottom of the V-shape. When α is too large (i.e., excessive inclination), if the length of the pre-filter 24 is too short, it will not be able to form a large lateral interception area, which will cause some oil smoke to flow into the fan system without being filtered. However, if the pre-filter 24 is increased, the production cost will undoubtedly increase. Therefore, considering the guiding and interception effects of the pre-filter 24 on the filtered oil and its production cost, etc., α can be limited to meet the following requirements: 10°≤α≤30°.

[0103] It should be noted that the pre-filter 24 can also be arranged in a U-shaped arrangement or similar arrangement to replace the above-mentioned V-shaped arrangement. In fact, as long as the pre-filter 24 includes the highest position of the first oil filter and the highest position of the second oil filter located at the two ends of the horizontal direction, the lowest position of the oil filter located between the highest position of the first oil filter and the highest position of the second oil filter, and the internal oil guide structure for guiding the filtered oil to the lowest position of the oil filter, and the head oil collection box 25 is arranged below the lowest position of the oil filter for collecting the filtered oil, the pre-filter 24 can be tilted at a certain angle relative to the horizontal plane, so that the filtered oil is always guided to the lowest position of the oil filter under the action of the internal oil guide structure and gravity, and the filtered oil finally flows into the head oil collection box 25 for centralized cleaning.

[0104] For example, when the front oil filter 24 includes the first oil filter part 242a, the transition connection part 242b and the second oil filter part 242c connected in sequence, the highest position of the first oil filter is located at the lateral outer end of the first oil filter part 242a, the highest position of the second oil filter is located at the lateral outer end of the second oil filter part 242c, and the lowest position of the oil filter is located at the transition connection part 242b. Alternatively, when the front oil filter 24 includes the first oil filter 241a and the second oil filter 241b which are independent of each other, the highest position of the first oil filter is located at the lateral outer end of the first oil filter 241a, the highest position of the second oil filter is located at the lateral outer end of the second oil filter 241b, and the lateral inner end of the first oil filter 241a and the lateral inner end of the second oil filter 241b are used as the lowest position of the oil filter. In short, when the front oil filter 24 is arranged in a V shape, the highest position of the first oil filter and the highest position of the second oil filter are respectively located at the two V-shaped top ends of the front oil filter 24, and the lowest position of the oil filter is located at the V-shaped bottom end of the front oil filter 24.

[0105] In one embodiment, referring to Figure 1 The body 1 includes a body oil collecting box 15 located below the stove 11, and the integrated stove 100 includes an external oil guiding structure, which is used to guide the filtered oil in the pre-filter module to the body oil collecting box 15. Under this structure, it is not necessary to set the head oil collecting box 25 in the front oil fume channel 22, thereby reducing the wind resistance in the front oil fume channel 22 and ensuring the smoke extraction efficiency of the integrated stove 100.

[0106] However, it should be noted that if the head oil collecting box 25 is provided, its cleaning frequency should be much higher than that of the body oil collecting box 15, so the user does not need to frequently bend down to remove the body oil collecting box 15. In other words, from the perspective of smoking performance, the integrated stove 100 of this embodiment is better, and from the perspective of cleaning and maintenance, the integrated stove 100 with the head oil collecting box 25 is better, so it can be selectively set according to the actual needs of the user.

[0107] In one embodiment, referring to Figures 19 to 21The pre-filter module includes a pre-filter 24, which is arranged in an eight-shaped shape and includes a first filter 241a and a second filter 241b that are independently arranged, and the pre-filter 24 can guide the filtered oil to the inner wall of the front oil fume channel 22. In addition, the integrated stove 100 also includes an external oil guide structure for guiding the filtered oil on the inner wall of the channel and then discharging it to the outside. Therefore, in addition to being configured to guide the filtered oil to the oil collecting box 15 of the fuselage, the external oil guide structure can also be configured to directly discharge the filtered oil outside the fuselage 1 (for example, it can be directly discharged to a sewer pipe, etc.).

[0108] By arranging the pre-filter 24 in an eight-shaped arrangement, it can be tilted at a certain angle relative to the horizontal plane, so that the filtered oil is always directed to the inner wall of the channel under the action of gravity, and the filtered oil flows along the inner wall of the channel to the external oil guide structure to be discharged externally, thereby ensuring that the flow path of the filtered oil bypasses the fan system 13 located below the front oil fume channel 22, so as to reduce the accumulation of oil stains on the fan system 13.

[0109] Typically, the inner wall of the channel includes a first channel side wall and a second channel side wall located on both sides in the transverse direction. In this case, the first oil filter 241a is used to guide the filtered oil outward to the first channel side wall, and the second oil filter 241b is used to guide the filtered oil outward to the second channel side wall. Of course, in some other embodiments, when the pre-filter 24 is arranged in an eight-shaped arrangement, a head oil collection box 25 can also be respectively arranged at the outer end of the first oil filter 241a and the outer end of the second oil filter 241b. In this case, the filtered oil directly flows into the head oil collection box 25, which is convenient for users to clean in a centralized manner.

[0110] In one embodiment, the external oil guide structure includes an annular oil receiving groove 28, which is arranged around the inner peripheral wall of the front oil fume channel 22 to receive the filtered oil on the inner peripheral wall of the channel. Obviously, by using the annular oil receiving groove 28 to first collect the filtered oil on the inner peripheral wall of the channel, it is more convenient to subsequently guide the filtered oil in a centralized manner.

[0111] In order to ensure that the flow path of the filtered oil avoids the fan system 13 located below the front oil fume channel 22, the filtered oil in the annular oil receiving groove 28 can be always directed to the outside. Therefore, the annular oil receiving groove 28 can be set as a bending groove. Specifically, the annular oil receiving groove 28 is provided with an upward bending position located in the middle, and the two sides of the upward bending position are respectively formed into a first semi-annular groove and a second semi-annular groove inclined downward. In this way, under the action of gravity, the filtered oil in the first semi-annular groove and the second semi-annular groove can be directed to their respective outsides.

[0112] In addition, a wall sealing connection can be formed between the groove circumferential wall of the annular oil receiving groove 28 and the inner circumferential wall of the channel to prevent the filtered oil from leaking downward from the gap between the groove circumferential wall of the annular oil receiving groove 28 and the inner circumferential wall of the channel, thereby improving the reliability of the annular oil receiving groove 28.

[0113] When the external oil guide structure includes other components such as an oil guide pipe (for example, an oil guide pipe connected between the annular oil receiving groove 28 and the fuselage oil collecting box 15), the component can also be preferably arranged away from the fan system 13. In other words, the external oil guide structure should preferably be arranged away from the fan system 13 as a whole.

[0114] In one embodiment, the first inclined angle between the first oil filter 241a and the horizontal plane can be set to β1, and the second inclined angle between the second oil filter 241b and the horizontal plane can be set to β2. Both β1 and β2 are acute angles.

[0115] Similarly, when β1 and β2 are too small (i.e., the degree of inclination is insufficient), the filtered oil may have difficulty in overcoming the viscous resistance to flow smoothly, resulting in the inability to be diverted to the inner wall of the channel on the outside. When β1 and β2 are too large (i.e., over-inclined), if the length of the first oil filter 241a and the second oil filter 241b is too short, a large lateral interception area cannot be formed, which will cause some oil smoke to flow into the fan system without being filtered. However, if the first oil filter 241a and the second oil filter 241b are increased, the production cost will undoubtedly increase. For this reason, considering the diversion and interception effects of the first oil filter 241a and the second oil filter 241b on the filtered oil and their production costs, β1 and β2 can be limited to meet the following conditions: 10°≤β1≤30° and / or 10°≤β1≤30°.

[0116] It should be noted that the first oil filter 241a and the second oil filter 241b can be respectively set as the aforementioned fixed structure or movable structure. When set as a fixed structure, it can be set as the aforementioned single-layer filter plate or multi-layer filter plate. When the first oil filter 241a and the second oil filter 241b are both set as single-layer filter plates or multi-layer filter plates, the outer end of the first oil filter 241a and the outer end of the second oil filter 241b are both provided with oil filter outlets. When set as a movable structure, the first oil filter 241a and the second oil filter 241b can be set as the aforementioned rotating filter.

[0117] In addition, the above-mentioned figure-eight arrangement of the pre-filter element 24 can be replaced by other similar arrangements, as long as the first oil filter element 241a and the second oil filter element 241b respectively extend downwardly from their respective lateral inner ends toward their lateral outer ends, so that the filtered oil in the pre-filter element 24 can be drained outward to the inner wall of the channel of the front oil fume channel 22, and an external oil guide structure is provided to drain the filtered oil on the inner wall of the channel and discharge it outside.
