Description

Technical Field

[0001] The present invention relates to a roaster with a multi-fan structure, in which more than two fans are arranged on a roasting rack body to effectively handle smoke generated during roasting and to minimize the phenomenon of air circulation along the inside of the roasting rack body, thereby minimizing the pollution of the internal structure of the air circulation roaster and achieving hygienic use and management. Background Art

[0002] Generally speaking, an air circulation oven that can draw in smoke generated during the grilling of food is intended to reduce the burning of food or the generation of smoke during the grilling process, and can do so by drawing in the smoke or odor and filtering it within the main body.

[0003] In addition, a suction and blowing fan is usually built into the main body, and air is circulated inside the device through air intake and air exhaust formed on the two side walls of the main body. An oil collecting pan for storing water is provided in the main body so that the oil contained in the air can be precipitated during the air circulation process.

[0004] However, although this air circulation type roaster can significantly reduce the odor or smoke during the roasting process and can be conveniently used indoors, if the air circulation type roaster is used continuously, due to the accumulation of oil or foreign matter on the suction and blowing fan itself or inside the main body, the air suction capacity of the suction and blowing fan will be reduced. Although the smoke will be guided to the air intake port, it cannot be completely inhaled and the smoke will still remain inside, which limits the smoke removal and deodorization effects.

[0005] Furthermore, due to the structure of air circulation inside the product, it is impossible to avoid the accumulation of oil or foreign matter in the body, so there are certain limitations in terms of hygienic use and management of the product. Summary of the invention

[0006] Technical issues

[0007] The present invention is proposed to solve the above-mentioned problems in the past. Its purpose is to provide a toaster with a multi-fan structure, in which more than two fans are arranged on the grill body to effectively absorb the smoke generated during the baking process, while at the same time eliminating the structure of air circulation inside the body as much as possible, ensuring stable purification or complete combustion of the air, so that the product itself can be used and managed hygienically.

[0008] Means of solving the problem

[0009] According to one aspect of the present invention, a toaster with a multi-fan structure is provided, comprising: a grill body, a toaster space with an open top formed on the inner side, and an external air inlet hole provided on one side, forming first and second ventilation holes facing each other across the toaster space; a drawer, combined with the grill body and provided with an air exhaust hole; a heating component, arranged on the grill body to dissipate heat to the toaster space; a first suction and blowing fan, arranged inside the grill body, sucking in external air through the external air inlet hole and blowing the air through the first ventilation hole to the toaster space toward the second ventilation hole; and a second suction and blowing fan, sucking in air blown to the toaster space by the first suction and blowing fan into the grill body through the second ventilation hole and exhausting the air through the air exhaust hole.

[0010] The grill may further include a filter unit, which is disposed at least one of the front and rear of the second suction and blowing fan on a flow path of air flowing into the interior of the grill body, and is used to filter air.

[0011] The filter unit can be arranged on the grill body in a replaceable manner.

[0012] The filter unit may be disposed behind the second suction and blowing fan on the flow path of the air flowing into the interior of the grill body, so that the air blown by the second suction and blowing fan contacts the water and is discharged through the air discharge hole, and may include water contained in the water containing space of the drawer.

[0013] The filter unit may further include a filter disposed on a flow path of air flowing into the grill body, at least one of between the second suction and blowing fan and the water receiving space and between the water receiving space and the air discharge hole.

[0014] The air discharge hole may be disposed behind the filter unit on a flow path of the air flowing into the grill body, so that the air filtered by the filter unit is discharged to the outside of the grill body.

[0015] The flow path of the air blown from the second suction and blowing fan and discharged through the air discharge hole is shielded by the drawer and the internal structure of the grill body, so that the air does not circulate inside the grill body but is directly discharged through the air discharge hole.

[0016] The drawer may integrally form the water receiving space on one side and an oil receiving space separated from the water receiving space on the other side so that oil generated during food cooking can drip.

[0017] The drawer can be detachably coupled to the grill body by sliding.

[0018] According to another aspect of the present invention, a roaster with a multi-fan structure is provided, comprising: a roasting grill body, one side of which is provided with an external air inlet hole, and the other side of which is provided with an air exhaust hole; a dividing plate, combined with the above-mentioned roasting grill body to form a roasting space, and forming a first ventilation hole and a second ventilation hole facing each other; a heating component, arranged in a manner of dissipating heat to the above-mentioned roasting space; a first suction and blowing fan, arranged inside the above-mentioned roasting grill body, sucking in external air through the above-mentioned external air inlet hole, and then blowing it to the above-mentioned roasting space toward the above-mentioned second ventilation hole through the first ventilation hole; and a second suction and blowing fan, sucking in air blown to the above-mentioned roasting space by the above-mentioned first suction and blowing fan into the inside of the above-mentioned roasting grill body through the above-mentioned second ventilation hole, and then exhausting it through the above-mentioned air exhaust hole.

[0019] The grill may further include a filter unit, which is disposed at least one of the front and rear of the second suction and blowing fan on a flow path of air flowing into the interior of the grill body, and is used to filter air.

[0020] The air discharge hole may be disposed behind the filter unit on a flow path of the air flowing into the grill body, so that the air filtered by the filter unit is discharged to the outside of the grill body.

[0021] The grill body may be formed with an internal guide hole to guide part of the air sucked into the second ventilation hole by the second suction and blowing fan to the heating component.

[0022] The grill body may be provided with an oil receiving pan, which is disposed on a flow path of air flowing toward the heating component through the internal guide hole and contains water so that the air contacts the water.

[0023] Effects of the Invention

[0024] The roaster with a multi-fan structure according to the present invention as described above has the following advantages: after the external air is sucked in by the first suction and blowing fan, the smoke (air) is sucked in by the second suction and blowing fan, and the smoke is filtered by a filter unit arranged at the second suction and blowing fan, and finally discharged directly to the outside of the grill body, thereby not only increasing the capacity and attraction of the multi-fan structure to suck in smoke, etc., but also eliminating the structure in which the smoke circulates inside the grill body, thereby minimizing the phenomenon of grease and the like being stained on the inside of the product itself, and realizing hygienic management and use of the device.

[0025] That is, by preventing the air flowing into the air flow path of the drawer from entering the lower space under the partition plate but being discharged directly through the air discharge hole, hygiene problems caused by oil, foreign matter, etc. adhering to the surface of the internal structure located in the lower space of the grill body can be fundamentally prevented.

[0026] In addition, the filtration unit includes water contained in the water containing space of the drawer and an additional filter for double filtration, thereby further reducing the pollution degree of the finally discharged air, and further preventing the air and indoor walls of the indoor space of the building using this product from being polluted.

[0027] Furthermore, by directing a portion of the smoke sucked in by the second suction and blowing fan to the heating component, the incompletely burned smoke is completely burned by the heating component, thereby having the advantages of reducing smoke generation, while reducing the amount of smoke filtered by the filter unit, thereby extending the service life of the filter.

[0028] Furthermore, an oil pan filled with water is arranged on the path leading the smoke to the heating component, so that the oil contained in the smoke can be precipitated by water, which has the advantage of not only filtering the oil but also reducing the contamination of the inside of the device caused by the oil contained in the smoke.

[0037] Hereinafter, embodiments of the present invention will be described in more detail with reference to the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but can be implemented in various forms, and these embodiments are provided only to make the disclosure of the present invention as complete as possible and to enable ordinary technicians to fully understand the scope of the invention. The same reference numerals in the accompanying drawings refer to the same elements.

[0038] According to the multi-fan structure toaster of the preferred embodiment of the present invention, more than two fans are arranged inside the product to effectively inhale the smoke (air) generated during the food baking process, and the inhaled air does not circulate inside the product, but is directly discharged to the outside of the product, thereby minimizing the adhesion of oil stains and the like caused by oil vapor, and realizing hygienic product management and use.

[0039] Furthermore, by completely burning part of the air generated during the baking process and flowing into the interior of the product, smoke generation is further reduced, which not only enables hygienic product management and use but also avoids consumer dissatisfaction.

[0040] That is, the present invention effectively inhales the smoke generated during the baking process while eliminating the structure of circulating air inside the main body through the fan as much as possible, ensuring stable purification or complete combustion of the air, so that the product itself can be used and managed hygienically.

[0041] Hereinafter, the present invention will be described in detail with reference to various embodiments.

[0042] like Figures 1 to 5 As shown, the roaster with a multi-fan structure according to the first embodiment of the present invention includes a roasting rack body 100 , a drawer 200 , a heating component 300 , a first suction and blowing fan 400 , and a second suction and blowing fan 500 .

[0043] First, a grill body 100 is provided with a baking space 110 with an open top, and a grill or a baking tray 120 is provided on the baking space for placing baked food. The baking space is formed by a depression of a predetermined depth, and a first ventilation hole 130 and a second ventilation hole 140 are formed on the grill body 100, facing each other and in the form of slits across the baking space.

[0044] The grill body 100 is provided with a partition plate 160 to divide the inner space into upper and lower parts to form a baking space 110 and a lower space 150 separated from the baking space 110 .

[0045] like Figure 2As shown, a slit-shaped external air inflow hole 170 is provided at one side of the grill body 100 so that external air with a relatively low temperature compared to the hot air generated in the baking space can flow into the grill body 100 .

[0046] Next, if Figure 3 and Figure 4 As shown, the heating component 300 is disposed on the grill body 100 to dissipate heat to the baking space 110 . The heating component 300 can be integrated with the bottom surface of the baking pan 120 or mounted on the partition plate 160 to be combined with the grill body 100 .

[0047] The heating member 300 may be formed of a rod bent in a predetermined shape, and generate heat when electricity is supplied.

[0048] Next, if Figures 1 to 5 As shown, the drawer 200 is detachably coupled to the lower portion of the grill body 100 in a sliding manner and is provided with an air discharge hole 210. That is, the drawer 200 can be completely separated from the grill body 100 and can be coupled to the grill body in a sliding manner, and the specific content will be described in detail below.

[0049] On the other hand, although not specifically shown in the figure, the drawer 200 can be fixed to the grill body 100, and the grill pan 120 and the partition plate 160 can be separated upward from the grill body 100, so that the drawer 200 is exposed to the outside.

[0050] In the embodiment of the present invention, a first suction and blowing fan 400 and a second suction and blowing fan 500 are built inside the grill body 100, so that external air is supplied or smoke (air) generated during the grilling process is sucked in through the first ventilation hole 130 and the second ventilation hole 140. Of course, these suction and blowing fans can be set to multiple according to their respective capacities.

[0051] like Figure 4 As shown, the first suction and blowing fan 400 is disposed inside the grill body 100, and after sucking in external air through the external air inflow hole 170, it is blown to the baking space 110 toward the second air vent 140 through the first ventilation hole 130. It should be explained that the first suction and blowing fan 400 is located at the first ventilation hole 130, and the external air sucked in through the external air inflow hole 170 formed on the lower surface of the grill body 100 is blown to the baking space 110 through the first ventilation hole 130. Among them, the external air inflow hole 170 can also be formed in the upper part of the grill body 100 near the first suction and blowing fan 400, rather than being formed in the lower part of the grill body 100.

[0052] like Figure 4 and Figure 5As shown, the second suction and blowing fan 500 sucks the air blown to the baking space by the first suction and blowing fan 400, sucks it into the interior of the grill body 100 through the second ventilation hole 140, and finally discharges it through the air discharge hole 210. It should be explained that the second suction and blowing fan 500 is arranged at a position relatively close to the second ventilation hole 140, and directly discharges the sucked air to the outside of the grill body through the air discharge hole 210 of the drawer 200.

[0053] That is, the present invention performs the following process in sequence: external air flows in -> the first suction and blowing fan blows -> the second suction and blowing fan inhales the air blown by the first suction and blowing fan -> the inhaled air is directly discharged to the outside of the grill body. During this process, the air does not circulate inside the grill body 100.

[0054] After external air is supplied to the baking space 110 by the first suction and blowing fan 400, the high-temperature oil vapor generated by the baking tray 120 heated during the baking process can be condensed by the relatively low-temperature external air, thereby reducing the generation of smoke. At this time, a filter unit 600 is provided at the second suction and blowing fan 500 to filter the oil, odor or smoke contained in the air during the inhalation of the smoke.

[0055] As described above, the present invention effectively inhales the smoke (air) generated during the food grilling process through the first suction and blowing fan 400 and the second suction and blowing fan 500, and ensures that the inhaled air does not circulate inside the grill body, but is directly discharged to the outside of the grill body 100 through the air discharge hole 210, thereby minimizing the phenomenon of oil stains and the like adhering to the surface of the internal structure of the grill body 100 due to oil vapor, thereby achieving hygienic product management and use.

[0056] like Figures 4 to 6 As shown, the present invention further comprises a filter unit 600, which is disposed at least one of the front and rear of the second suction and blowing fan 500 on the flow path of the air flowing into the interior of the grill body through the second ventilation hole 140, for filtering the air.

[0057] In an embodiment of the present invention, the filter unit 600 may include a conventional high-efficiency particulate air filter (HEPA filter), a water filter that includes moisture that can precipitate oil and the like included in oil vapor, a structure that allows smoke (air) to contact water in a state where the water itself is contained in a tray, etc. to precipitate oil and the like, an activated carbon filter for removing odors, etc., a photocatalytic filter with antibacterial function, and the like, and may be arranged alone or in multiple forms in front of or behind the second suction and blowing fan 500 or on both sides of the front and rear.

[0058] According to the multi-fan structure and the filter unit 600 composed of the first suction and blowing fan 400 and the second suction and blowing fan 500, the smoke generated during the grilling process is sucked in and the oil and odor are filtered, and the smoke is eliminated from circulating as a whole inside the grill body 100, thereby minimizing the phenomenon of oil stains adhering to the internal wall or structure of the grill body 100, thereby facilitating the hygienic management of the product.

[0059] Specifically, in an embodiment of the present invention, Figures 4 to 6 As shown, the filter unit 600 is arranged behind the second suction and blowing fan 500 on the flow path of the air flowing into the grill body 100, so that the air flowing into the grill body 100 and blown by the second suction and blowing fan 500 contacts with the water and is then discharged through the air discharge hole 210. The filter unit 600 includes water contained in the water receiving space 220 of the drawer 200.

[0060] That is, the oil, foreign matter, etc. contained in the air passing through the second suction and blowing fan 500 can come into contact with the water contained in the water containing space 220 and precipitate. The air with the oil and foreign matter removed is discharged to the outside through the air discharge hole 210, thereby further preventing the indoor space where the product of the present invention is used from being polluted.

[0061] And, if Figure 6 As shown, the filter unit 600 may further include a filter 610, which is disposed at least one of the following locations: between the second suction and blowing fan 500 and the water receiving space 220, and between the water receiving space 220 and the air discharge hole 210, on the flow path of the air flowing into the grill body 100. Figure 5 As shown, the filter 610 may also be disposed in front of the second suction and blowing fan 500 .

[0062] Here, the filter 610 may be formed in various forms such as the aforementioned HEPA filter, activated carbon filter, photocatalytic filter, etc., and may be disposed on the grill body 100 in a replaceable installation manner.

[0063] Furthermore, the filter 610 can be arranged in front of the second suction and blowing fan 500, between the second suction and blowing fan 500 and the water receiving space 220, and between the water receiving space 220 and the air discharge hole 210. For the convenience of illustration, the relevant drawings usually show that one is set for each.

[0064] like Figure 5As shown, if the filter 610 is arranged in front of the second suction and blowing fan 500, the oil in the oil vapor generated in the baking space 110 is first filtered through the filter and then moved to the second suction and blowing fan, thereby minimizing the contamination of the second suction and blowing fan 500 and minimizing the phenomenon of reduced durability of the fan, and can also further reduce the precipitated oil, foreign matter, etc. in the water contained in the water containing space 220.

[0065] And, if Figure 6 As shown in (a), if the filter 610 is arranged between the second suction and blowing fan 500 and the water receiving space 220, the phenomenon of oil, foreign matter, etc. precipitating in the water received in the water receiving space 220 can be further reduced, thereby further reducing the occurrence of contamination of the water receiving space 220 of the drawer 200.

[0066] And, if Figure 6 As shown in (b), if the filter 610 is arranged between the water receiving space 220 and the air discharge hole 210, the oil and foreign matter are first precipitated in the water received in the water receiving space 220, and the tiny foreign matter is filtered again by the filter 610, and the clean air is discharged into the indoor space, thereby further preventing the indoor space where the product of the present invention is used from being polluted.

[0067] In an embodiment of the present invention, the air discharge hole 210 is preferably formed behind the filter unit 600 on the flow path of the air flowing into the grill body 100 to ensure that the air filtered by the filter unit 600 is discharged to the outside of the grill body 100 .

[0068] The drawer 200 is provided with an air flow path 230 so that the air passing through the water receiving space 220 can be discharged through the air discharge hole 210 , and the air discharge holes 210 are respectively formed at the side portion and the lower portion of the drawer 200 .

[0069] In an embodiment of the present invention, Figure 3 As shown, the drawer 200 can be detachably coupled to the grill body 100 in a sliding manner, integrally forming a water receiving space 220 on one side and an oil receiving space 240 separated from the water receiving space 220 on the other side, so that the oil generated during the cooking process can drip. Therefore, when the user separates the drawer 200 from the grill body, the drawer 200 having both the water receiving space 220 and the oil receiving space 240 is separated from the grill body. An oil drain hole 180 is provided in the central portion of the grill pan 120 and the partition plate 160, and the oil passing through the oil drain hole 180 will fall into the oil receiving space 240 of the drawer 200 and be collected.

[0070] On the other hand, as mentioned above, the present invention ensures that the air does not circulate inside the grill body, but is directly discharged to the outside of the grill body 100 through the air discharge hole 210, thereby minimizing the phenomenon of oil stains and the like adhering to the internal structure surface of the grill body 100 due to oil vapor, such as Figure 5 As shown, the flow path of the air discharged through the air discharge hole 210 by the second suction and blowing fan 500 is shielded by the internal structure of the drawer 200 and the grill body 100, so that the air does not circulate inside the grill body 100 but is directly discharged through the air discharge hole 210.

[0071] That is, the air flowing into the air flow path 230 of the drawer 200 does not flow into the lower space 150 below the partition plate 160, but is directly discharged through the air discharge hole 210. Thus, the hygienic problem caused by the adhesion of oil, foreign matter, etc. to the surface of the internal structure of the lower space 150 of the grill body 100 can be fundamentally prevented.

[0072] In order to prevent such air circulation, the internal structure of the grill body 100 near the air flow path 230 and a portion of the drawer 200 can be elastically and tightly kept in contact with each other, thereby preventing air from flowing into the lower space 150 .

[0073] Specifically, if Figure 7 As shown, a shielding member 190 made of elastic material such as rubber, silicone, epoxy resin, etc. is added to the inner structural surface of the grill body 100 near the air flow path 230 and in contact with a portion of the drawer 200, thereby further enhancing the aforementioned effect.

[0074] Embodiments for carrying out the invention

[0075] Hereinafter, a roaster with a multi-fan structure according to a second embodiment of the present invention will be described.

[0076] The roaster with a multi-fan structure in the second embodiment of the present invention is different from the first embodiment in terms of the structure of the roasting rack body and the structure of the partition plate.

[0077] like Figure 8 As shown, the roaster with a multi-fan structure according to the second embodiment of the present invention comprises a roasting rack body 11 , a partition plate 14 , a heating component 20 , a first suction and blowing fan 21 and a second suction and blowing fan 22 .

[0078] First, a grill body 11 is provided with a baking space 12 with an open top inside, and a grill or a baking tray 13 is provided on which baked food can be placed in the baking space 12. The baking space 12 is formed by being recessed to a predetermined depth, and an external air inflow hole 23 is formed on one side (upper side), and an air exhaust hole 24 is formed on the other side (lower side).

[0079] The grill body 11 is provided with a partition plate 14 to divide the inner space of the grill body 11 into upper and lower parts to form a baking space 12 and a lower space 17 separated from the baking space 12. In addition, an additional internal heat dissipation plate 18 may be provided below the partition plate 14 to separate and form a heat dissipation space 19.

[0080] like Figure 8 As shown, a slit-shaped external air inflow hole 23 is provided on one side of the grill body 11 so that external air with a relatively low temperature compared to the hot air generated in the baking space can flow into the grill body 11 .

[0081] The partition plate 14 is combined with the grill body 11 to form a baking space 12 , and a first ventilation hole 15 and a second ventilation hole 16 are formed respectively, which are opposite to each other and are in the form of slits across the baking space.

[0082] Next, the heating component 20 is disposed on the grill body 11 to dissipate heat to the baking space 12 . The heating component 20 can be combined with the grill body 11 in a manner of being integrated with the bottom surface of the baking pan 13 or being installed on the partition plate 14 .

[0083] The heating member 20 may be formed of a rod bent into a predetermined shape, and generates heat when electricity is supplied.

[0084] In the embodiment of the present invention, a first suction and blowing fan 21 and a second suction and blowing fan 22 are built into the grill body 11, so that external air is supplied or smoke (air) generated during the grilling process is sucked in through the first ventilation hole 15 and the second ventilation hole 16. Of course, these suction and blowing fans can be set to multiple according to their respective capacities.

[0085] like Figure 8 As shown, the first suction and blowing fan 21 is disposed inside the grill body 11, and after sucking in external air through the external air inlet hole 23, the external air is blown to the baking space 12 toward the second air hole 16 through the first ventilation hole 15. It should be explained that the first suction and blowing fan 21 is located at the first ventilation hole 15, and the external air sucked in through the external air inlet hole 23 formed on the upper surface of the grill body 11 is blown to the baking space 12 through the first ventilation hole 15.

[0086] The second suction and blowing fan 22 sucks the air blown to the baking space by the first suction and blowing fan 21, and then sucks it into the grill body 11 through the second ventilation hole 16, and finally discharges it through the air discharge hole 24 of the grill body 11. It should be explained that the second suction and blowing fan 22 is arranged at a position relatively close to the second ventilation hole 16, and directly discharges the sucked air to the outside of the grill body through the air discharge hole 24.

[0087] That is, the present invention performs the following process in sequence: external air flows in -> the first suction and blowing fan blows -> the second suction and blowing fan inhales the air blown by the first suction and blowing fan -> the inhaled air is directly discharged to the outside of the grill body. During this process, the air is not circulated inside the grill body 11 as much as possible.

[0088] After external air is supplied to the baking space 12 by the first suction and blowing fan 21, the high-temperature oil vapor generated by the baking tray 13 heated during the baking process can be condensed by the relatively low-temperature external air, thereby reducing the generation of smoke. At this time, the second suction and blowing fan 22 is provided with filter units 25 and 26 to filter the oil, odor or smoke contained in the air during the inhalation of the smoke.

[0089] As described above, the present invention effectively inhales the smoke (air) generated during the food grilling process through the first suction and blowing fan 21 and the second suction and blowing fan 22, and ensures that the inhaled air does not circulate inside the grill body, but is directly discharged to the outside of the grill body 11 through the air discharge hole 24, thereby minimizing the phenomenon of oil stains and the like adhering to the surface of the internal structure of the grill body 11 due to oil vapor, thereby achieving hygienic product management and use.

[0090] like Figure 8 As shown, the present invention further includes filter units 25, 26, which are arranged at least one of the front and rear of the second suction and blowing fan 22 on the flow path of the air flowing into the grill body 11 through the second ventilation hole 16, for filtering the air.

[0091] In an embodiment of the present invention, the filter units 25 and 26 may include a conventional high-efficiency particulate air filter (HEPA filter), a water filter that includes moisture that can precipitate oil and the like included in oil vapor, a structure that allows smoke (air) to contact water in a state where the water itself is contained in a tray, etc. to precipitate oil and the like, an activated carbon filter for removing odors, etc., a photocatalytic filter with antibacterial function, and the like, and may be arranged individually or in multiple forms in front of or behind the second suction and blowing fan 22, or on both sides of the front and rear.

[0092] In the relevant drawings, as an example, the filter units 25 and 26 are shown to be arranged in front of and behind the second suction and blowing fan 22 in the air flow path.

[0093] According to the multi-fan structure and filter units 25 and 26 formed by the first suction and blowing fan 21 and the second suction and blowing fan 22, the smoke generated during the grilling process is sucked in and the oil and odor are filtered, thereby minimizing the overall circulation of the smoke inside the grill body 11, thereby minimizing the phenomenon of oil stains adhering to the internal wall or structure of the grill body 11, thereby facilitating the hygienic management of the product.

[0094] Here, the filter may be formed in various forms such as the aforementioned HEPA filter, activated carbon filter, photocatalytic filter, etc., and may be disposed on the grill body 11 in a replaceable installation manner.

[0095] If the filter is arranged in front of the second suction and blowing fan 22, the oil content in the oil vapor generated in the baking space 12 is first filtered through the filter and then moved to the second suction and blowing fan, thereby minimizing the contamination of the second suction and blowing fan 22 and minimizing the phenomenon of reduced durability of the fan.

[0096] Furthermore, if a filter is disposed in front of the second suction and blowing fan 22, the air filtered by the two filters for oil, foreign matter, etc. is discharged to the indoor space outside the grill body through the air discharge hole 24, thereby further preventing the indoor space where the product of the present invention is used from being polluted.

[0097] In the embodiment of the present invention, to ensure that the air filtered by the filter units 25 and 26 is discharged to the outside of the grill body 11 , the air discharge hole 24 is preferably formed behind the filter units 25 and 26 on the flow path of the air flowing into the grill body 11 .

[0098] And, if Figure 8 As shown, the grill body 11 forms an internal guide hole 27 to guide part of the air sucked into the second ventilation hole 16 by the second suction and blowing fan 22 to the lower space 17 of the grill body 11 , specifically to the heating component 20 .

[0099] The internal guide hole 27 is located on the other side of the second suction and blowing fan 22, and is connected to the panel through hole 28 formed on the partition plate 14 and the internal heat dissipation plate 18 to guide the smoke to the heating component 20, thereby reheating the smoke through the heating component 20, so that the incompletely burned smoke is completely burned, reducing the generation of smoke, while reducing the filtering burden of the filter units 25 and 26, extending the service life of the filter and facilitating replacement.

[0100] In addition, the grill body 11 is further provided with an oil receiving pan 30, which is disposed on the flow path of air flowing to the heating unit 20 through the internal guide hole 27 and receives water so that the air and the water come into contact. The oil receiving pan 30 can be detachably coupled to the grill body by sliding forward and backward according to the drawings.

[0101] On the other hand, while part of the smoke is guided to the heating element 20 through the internal guide hole 27 as described above, the oil receiving pan 3 filled with water is located on the path of the smoke, so that the smoke contacts the water and the oil etc. are precipitated.

[0102] As a result, a portion of the smoke directed to the heating component 20 is deoiled at the oil receiving pan 30, thereby reducing the combustion burden of the heating component 20 and the reduction in cleaning efficiency or thermal efficiency due to smoke adhering to the surface of the heating component 20. The oil receiving pan 30 can be detachably arranged on the baking body to collect the oil generated during the baking process and drip the oil through the panel through hole 28 or other oil drainage holes.

[0103] Above, the present invention is illustrated and described with reference to the preferred embodiment for illustrating the principle of the present invention, but the present invention is not limited to the structure and function so illustrated and described. In fact, it can be understood by ordinary technicians that various modifications and changes can be made to the present invention without departing from the idea and scope of the attached claims.

[0104] Industrial Applicability

[0105] The present invention can effectively absorb the smoke generated during the baking process by configuring more than two fans on the main body, while trying to eliminate the structure of air circulation inside the main body, ensuring stable purification or complete combustion of the air, so that the product itself can be used and managed hygienically, and has industrial applicability in this respect.
