為垂直狀，與其對向之内箱之外壁面及載置環或外箱之内 面壁亦為垂直狀’故吸引空間上部之經間隔之内外側部位 成為上下方向之直線流路，而且排氣之吸引孔形成於垂直 之内周環狀壁部，因此排氣之吸引方向為大致水平，結果 使得被吸引之排氣碰撞至間隔環狀壁部之上部後，其下方 平坦而無碰撞部分，所含油脂類等之附著量減少，從而朝 向吸引空間之下游側之排氣中所含之油脂類等有可能大量 201216910 殘留’進而頂環中之所含油脂類等之附著面位於内周環狀 壁部與間隔環狀壁部之間之狹窄空間内，故清洗作業較為 困難，且無法完成得乾淨澈底，而且費時。 又，上述專利文獻3所記裁之發明存在如下必需解決 之課題··由於狹縫朝向中心側且朝向上方，故即使在上述 專利文獻2所記載之發明中採用該狹縫，被吸引之排氣亦 僅會朝向斜下方吸引後輕微地彎肖，故被吸引之排氣朝向 間隔環狀壁部之碰撞程度較輕，所含油脂類等之附著量亦

TECHNOLOGICAL FIELD The present invention relates to a smokeless grilling device which has an exhaust gas which is introduced into the outside air to lower the temperature of the exhaust gas in a warm state to prevent internal overheating, and to exhaust the exhaust gas. The oil and fat contained in the product are immediately removed after the attraction. [Prior Art] Conventionally, in a smokeless grill that prevents overheating of inner and outer boxes, etc., an exhaust gas cooling structure of the following smokeless grill has been developed: a box having an upper opening portion disposed under the table = The inner box is disposed inside, and the crown member is placed above the gap between the inner circumferential surface of the opening formed on the table and the upper portion of the inner box, and is formed by the partition wall portion provided at the τ portion of the crown member. The upper part of the suction space between the outer box and the inner box is spaced apart from the inner side and the outer side, and the suction hole of the exhaust is formed on the exhaust suction flow path of the inner part, and the outer air attracting flow path forms the outer air suction on the outer side. In the opening portion, when the exhaust gas is sucked, the outside air is sucked from the suction opening portion into the external air suction flow path, and flows along the inner wall surface of the outer casing, so that the exhaust gas from the inner peripheral high temperature state is not The outer wall surface of the outer casing is directly contacted, and the oil or the like contained in the exhaust gas does not adhere to the inner wall surface, whereby the outer casing does not overheat (for example, see Patent Document 1). However, the above-mentioned patent document 、 i i i μ i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i i As shown in ~5, the load is the partition wall, so the top 5 201216910 ring and the mounting ring will be in contact with the exhaust gas, which may cause pollution. Therefore, in order to solve the above problems, the applicant of the present invention has developed a top ring that is detachably disposed above the suction space for a smokeless grill having an exhaust gas cooling structure, and the exhaust gas cooling structure includes a lower portion disposed under the table The outer box having the upper opening portion and the inner box disposed inside the outer box 'is spaced apart from the upper portion of the suction space formed between the outer box and the inner box as the inner and outer portions, and the exhaust portion at the inner portion is attracted An air suction port is formed on the flow path, and an external air suction port is formed on the outer air suction flow path at the outer portion t. The top ring includes a crown member disposed on the inner circumference of the opening of the table An upper portion of the gap with the upper portion of the inner box; the inner peripheral annular wall portion 'continuously formed downward from the peripheral portion of the crown member, and the lower end portion and the inner box are $ μ Μ ^ β , above and below a 4-position overlap; and a spacer annular wall portion disposed outside the inner circumferential annular wall portion and having the upper end portion integrated with the lower surface of the crown member, and the upper portion of the upper 4 and the second reference portion between It is an inner-outer part; by forming a ^ ^ ^ ^ ^ in the upper part of the upper part of the inner wall of the inner wall of the above-mentioned ^-shaped wall portion, the punching hole and the guiding hole are formed, and the spacing is annular. The surface is vertical, so that the resistance is reduced by rTF> 4 > the flow of gas becomes (four), ^ makes the exhaust and the external space 7 Ai pay m', so as to go along the outer box of the outside coffee ah a + 耆 juice phase In the way of the inner wall surface, the laminar flow of the outer part of the air is stable, and the interval is strong and the 吏 is integrated by the crown member and the inner peripheral annular wall shyness to form a zero contact to the a1 ★ By this, the exhaust gas is not placed on the spacer of one of the top members, and the outer casing is placed on the outer side (see, for example, Patent Document 2). The applicant of the present invention has also developed the following non-thermal partition wall smokeless barbecue δ 201216910. The suction suction structure is formed as a slit formed between the inner peripheral edge portion of the top ring and the upper end portion of the inner box side, instead of In the invention described in the above-mentioned Patent Document 2, the plurality of exhaust suction holes are formed in the inner circumferential annular wall portion, and the inner circumferential annular portion is not formed in the inner peripheral portion of the top ring (for example, see Patent Document 3) ° [ [Patent Document 1] [Patent Document 1] Japanese Patent No. 3627953 (Patent Application No. 1, Paragraph No. [〇〇〇5], Figs. 3 to 5) [Patent Document 2] Japanese Patent Laid-Open Japanese Patent Laid-Open Publication No. Hei. No. Hei. No. Hei. No. 5, No. 5, No. 5, No. 5, No. 5, No. 5, No. In the invention described in Patent Document 2, in order to stabilize the laminar flow of the outside air, the partition wall is only a circumferential wall, and the inner and outer wall surfaces are formed vertically, and the inner and outer walls are opposed to the inner box. The wall surface and the inner wall of the mounting ring or the outer box are also vertical. The outer portion of the portion is a straight-line flow path in the vertical direction, and the suction hole of the exhaust gas is formed in the vertical inner circumferential annular wall portion, so that the suction direction of the exhaust gas is substantially horizontal, and as a result, the attracted exhaust gas is attracted. After hitting the upper part of the partitioned annular wall portion, the lower portion is flat and there is no collision, and the amount of grease or the like contained therein is reduced, so that the oil and fat contained in the exhaust gas toward the downstream side of the suction space may be large 201216910 The residual surface of the residue and the grease contained in the top ring is located in a narrow space between the inner circumferential annular wall portion and the spaced annular wall portion, so that the cleaning operation is difficult and cannot be completed cleanly and time-consuming. . Further, the invention described in the above-mentioned Patent Document 3 has a problem to be solved as follows: Since the slit faces the center side and faces upward, even if the slit is used in the invention described in Patent Document 2, the row is attracted. The gas is only slightly inclined toward the obliquely downward direction, so that the attracted exhaust gas is less likely to collide toward the spaced annular wall portion, and the amount of grease or the like contained therein is naturally reduced. [Means for Solving the Problem] The present invention is based on the above-described conventional technique, in which the suction flow path is linear in the vertical direction because the slit faces the center side and faces upward, so the exhaust gas is circumferentially spaced. In the case where the degree of collision of the wall portion is relatively low, the above-described problem is solved in that the inner peripheral edge portion of the annular wall portion of the crown member in the top ring is inclined downward toward the center side, and the cooking is carried out by means of cooking. The mounting portion enlarges the diameter of the upper end portion of the inner box, and gradually enlarges the portion above the mounting portion toward the upper side, and forms an annular wall portion at the intermediate portion according to the expanded diameter shape of the inner box. The tapered surface of the reduced diameter is such that the inner diameter of the portion lower than the tapered surface is smaller than the inner diameter of the upper portion, thereby making the suction flow path of the exhaust gas have a curved shape, and the inner control is smaller than the inner box The upper opening #, and the upper end portion of the inner box is lower than the inner peripheral portion of the top portion, and the exhaust suction portion is formed as a row formed between the inner peripheral portion of the top portion and the upper end portion of the inner box. Gas suction slit, thereby making the exhaust Primer slit toward the center and toward the left foot, so that obliquely downward deflection immediately after the exhaust gas flowing through the top of 8,201,216,910 suction. [Effects of the Invention] The present invention includes an inner box having an upper open outer box and an inner box disposed under the table, and an attraction space is formed between the outer box and the inner box. The top ring is detachably seated on the mounting section of the mounting ring provided in the opening of the table, and the mounting ring is provided so that the inner peripheral edge portion of the mounting section is continuously formed downward. The lower end portion of the wall portion is located in the upper opening portion of the outer box, and the gap between the inner peripheral surface of the opening portion of the closing table and the upper portion of the outer box forms an exhaust port communicating with the exhaust path in the outer box, the top portion The ring includes: a crown member disposed above a gap between an inner circumferential surface of the opening of the table and an upper portion of the inner box; and a spacer annular wall portion disposed at an inner peripheral portion of the crown member The outer side is integrated with the lower surface of the crown member, and the upper portion of the suction space is partitioned into an inner and outer portion; i is provided at an inner portion of the suction space formed by spacing the annular wall portions Exhaust part of the exhaust, on the outer part The suction portion that is provided with the outside air is sucked into the suction flow path from the exhaust suction portion, and the exhaust gas containing oil or grease or oil mist is separated from the annular wall portion and does not contact the outer casing. The outer wall of the inner wall attracting the inner wall of the flow path is formed by the inner air of the outer air suction portion and the outer air in the suction flow path flows along the inner wall surface of the outer case to form a laminar flow, so that the sucked exhaust gas is The laminar flow is blocked, the wall surface of the Xiao W is not directly in contact with it, and the dirt on the W surface of the outer box is extremely small, and as a result, the temperature of the outer box can be suppressed and the oil contained in the exhaust gas The inner wall surface of the partitioned annular wall portion 201216910 and the inner wall surface of the inner box of the top ring of the 曰 清 清 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着 附着It is needless to say that the oils and fats adhering to the lower part can be suppressed to a very small amount, and the oil and fat stored in the exhaust path in the smokeless grill can be suppressed to a very small amount, so that even In case of self-venting attraction The inhalation of a food containing a large amount of oil and fat components on a placing and cooking means, and a flame generated when heated, is also removed before contacting the grease in the exhaust path, thereby preventing the catheter ( The occurrence of a fire, so that an emergency stop caused by the operation of a safety device such as a working refractory damper (nredamper) can be avoided as much as possible. Further, since a wide space for agitating the exhaust gas and the outside air can be ensured, the exhaust gas and the outside air can be efficiently removed, and the low temperature and dilution effect of the exhaust gas can be provided. Therefore, the main cause of the fire disappears, so that it can have a further fire prevention effect. Further, most of the fats and the like of the F-rolled T can be attached to the top ring', specifically, to the spacer annular wall portion, and the attachment to the inner surface of the external air suction flow path including the inner wall surface of the outer casing is suppressed. It is easier to clean up. In addition, since the crown member and the spaced annular wall portion are integrated, the rigidity of the top ring itself is improved and it is not easily deformed. The number of parts after disassembly is only "solid", so it is easy to manage and can be improved by productivity. The production cost is set such that the upper end portion of the inner peripheral portion 10 201216910 of the crown member in the top ring is inclined toward the center side, and the upper end portion of the inner box is expanded by the placing portion of the cooking means. The portion above the mounting portion is gradually expanded upward, so that the inner diameter of the top ring is smaller than the upper opening diameter of the inner box, and the upper end portion of the inner box is lower than the inner peripheral portion of the top ring, The exhaust suction/suction portion is an exhaust suction slit formed between the inner peripheral edge portion of the top ring and the upper end portion of the inner box, and has an enlarged diameter shape of the inner phase of the inner plug, so that the annular annular portion is at the intermediate portion. Forming a tapered surface having a reduced diameter, and making the inside of the portion lower than the tapered surface smaller than the inner diameter of the upper t μ y and the upper $ position, so when the exhaust suction slit is oriented toward the center side and facing downward And tilted by the top of the top ring When the portion is sucked toward the slanting side and sucks from the burning portion of the mounting portion, the combustion exhaust gas collides with the lower surface of the inner peripheral portion of the crown member at the upper end side of the annular wall portion. The inner wall surface is then biased downward and passes through the curved inner portion of the suction space to collide with the tapered surface of the annular wall portion or the outer wall of the enlarged diameter portion of the inner box, so that it can be attached to capture more Oils and the like, whereby the lower end of the inner wall surface of the outer casing can be attached to the lower end of the ring wall.油脂 卩 的 的 的 的 的 的 的 的 的 的 的 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方 下方The cleaning frequency or the cleaning frequency of the inner wall surface of the mounting % or 2 is kept constant, and the cleaning operation of the oil or the like contained in the time of the month is facilitated, and the cleaning time can be shortened. Therefore, although some of the oils and fats that cannot be caught on the upstream side will accumulate in the bottom of the box, which cannot be attached or detached from the top surface of the top plate, but can prevent the greasers from adhering to the inner wall of the outer box. And the bottom surface of the 201216910 outer surface is used as the oil accumulation portion to accumulate oil, and the amount of adhesion of the grease to the inner wall surface of the detachable top ring and the outer wall of the detachable inner box are increased, thereby By reducing the throughput toward the downstream, it is possible to reduce the cleaning area by not only defining the clear portion, but also to reduce the degree of dyeing of the portion. This makes it possible to save the cleaning operation of the outer box. Further, since the exhaust suction slit is sucked, the annular wall portion and the inner wall attached to the outer wall of the top ring and the inner box are more easily captured, so that the suction can be prevented as much as possible. Since the exhaust gas is repeatedly collided to the upper surface of the outer wall of the tank, the chance of the oil or the like is increased. Therefore, the oil-and-fat is made to flow to the downstream side of the exhaust passage portion without a wall: the inner side of the annular wall portion The lower surface of the inner peripheral side of the inner wall surface of the acoustic annular wall portion and the cleaning liquid or the cleaning liquid are cleaned. This can be reliably cleaned by the cleaning tool at a relatively small interval between the crown members. By the shape, the strength of the top ring can be further improved. The curved shape is continuously formed in the top ring from the lower side of the crown member, which is formed on the side of the center toward the center side. Above...therefore, the side wind on the top ring is called the deviation time, and the rise of the second and second exhausts extends the leakage of the exhaust gas toward the room, and the abundance can reduce the displacement due to the adhesion. The strength of the ¥ is further improved. If the surface is flowing down, if the oil is so as to be liquidified and then attached straight, the lower end of the annular wall will be dropped from 12 201216910 to the outer box. At the bottom, since the oil accumulation portion is provided on the inner circumference of the lower end portion of the annular wall portion in the top ring, the oil or the like that flows down the adhesion surface is accumulated in the oil accumulation portion, thereby preventing dripping and cleaning the top ring. When it is collected, the amount of oil accumulated on the bottom surface of the outer casing can be further reduced, whereby the cleaning operation of the outer casing can be further reduced, and the practical effect is considerable.
