The nozzle 14 is provided with a flow rate adjusting valve operated by an operation knob 15 provided on the side surface of the case 5, and the tip of the nozzle 14 is disposed so as to face the suction port 4 b 1 of the mixing tube portion 4 b of the burner 4. Yes. Primary air corresponding to the gas flow rate can be sucked from the suction port 4b1 of the mixing tube portion 4b of the burner 4.

  The burner 4 is a Bunsen burner 4 having a mixing tube portion 4b and a head portion 4a. The burner 4 is housed inside the case 5, but is arranged so that the inlet 4 b 1 of the mixing tube portion 4 b faces the cylinder mounting portion 3 and the head portion 4 a is located in the cooking portion 6. . That is, in the cooking unit 6 of this example, the head unit 4 of the burner 4 for combusting the gas supplied from the gas cylinder 2 loaded in the cylinder mounting unit 3 is provided, and the food can be baked by the combustion of this gas. Has been. In this example, the burner 4 is an internal flame type burner 4 that burns gas at the inner peripheral portion of the head portion 4a formed in a ring shape. However, the burner 4 is an outer portion that burns gas at the outer peripheral portion of the head portion 4a. A flame type burner 4 may be used.

  The interior of the case 5 is appropriately divided into several spaces by a vertical wall erected from the bottom plate 5a. For example, as the vertical wall, there is a cylinder space partition wall 16 that partitions an exhaust passage 9 described later and a gas cylinder storage space 12 of the cylinder mounting portion 3. The vertical wall includes a cylindrical wall 17 provided substantially at the center of the case 5. The in-cylinder space of the cylindrical wall 17 is opened above the case 5, that is, this part becomes a recess 18 surrounded by the cylindrical wall 17, which is recessed from the upper surface of the case 5. ing. The recess 18 is a cooking unit 6 in which the head portion 4a of the burner 4 is disposed and the food is baked. Specifically, in the recess 18, a food placement member 19 such as a wire mesh 19 a or a perforated iron plate for placing food on the head portion 4 a of the burner 4 is detachably mounted, together with the head portion 4 a. The cooking unit 6 is configured. Needless to say, the cooking unit 6 is located in the vicinity of the upper surface of the case 5 (that is, the upper surface portion of the case 5) in order to facilitate the baking operation of the ingredients. Moreover, in this example, the saucer 20 which receives the broth dripping when baking a foodstuff is provided in the bottom face of the recess 18 so that attachment or detachment is possible. The tray 20 is attached to the case 5 with an appropriate gap, and the gap ensures the inflow of secondary air used for gas combustion from the lower space of the case 5. The lower space of the case 5 is secured by placing the cassette stove 1a on an arbitrary stove placing surface such as a table via legs 25 that are suspended from the four corners of the lower surface of the case 5. ing. The leg portions 25 are individually adjustable in height.

  In addition, the space outside the cylinder wall 17 that is the space inside the case 5 is an exhaust that exhausts smoke and odor generated when the food is baked in the cooking unit 6 from an air inlet 7 provided around the cooking unit 6. It is a passage 9. The intake port 7 of this example is provided around the cooking unit 6 in the recess 18 so as to surround the periphery, and specifically, on the peripheral surface of the cylindrical wall 17 surrounding the recess 18. The plurality of through holes 7a are arranged in a row. The exhaust passage 9 is formed so as to reach an exhaust port 8 provided on the side of the case 5 opposite to the cylinder mounting portion 3. In the middle of the exhaust port 8 from the intake port 7 of the exhaust passage 9, A filter 10 and a fan 11 are disposed in this order from the intake port 7 side.

  The fan 11 is for sucking air from the air inlet 7 and exhausting it from the air outlet 8 through the exhaust passage 9, and a known axial fan or centrifugal fan can be applied. In this example, a drum type fan 11a (cross flow fan) is used in which the axial direction is the same as the width direction of the exhaust passage 9 and the axial length extends over substantially the entire width of the exhaust passage 9. The drive portion 21 arranged outside the exhaust passage 9 (that is, outside the side surface of the case 5) can be driven to rotate. The drive unit 21 is composed of a motor that rotates using a dry battery as a power source.

  The filter 10 is for removing smoke and odor, and a known activated carbon filter or grease filter can be applied. Specifically, the filter 10 is formed by stretching a filter medium 10b that removes smoke and odors that are passed through a rectangular frame material 10a, and can be replaced through a filter replacement port 22 provided in the case 5. It can be arranged in the exhaust passage 9. In this example, the filter replacement port 22 is provided on the upper surface of the case 5. The filter 10 is fitted so that both end portions of the filter 10 are vertically slidable on rail members 23 arranged at both widths of the exhaust passage 9, and the lower edge thereof is placed on the bottom plate 5 a of the case 5. Thus, the exhaust passage 9 is arranged to be closed. When the filter 10 is disposed in the exhaust passage 9 in this manner, the frame member 10a on the upper edge of the filter 10 is located in the filter replacement port 22 so that the filter replacement port 22 can be closed. 9 is prevented from leaking smoke or the like.

  The top plate 5b constituting the upper surface of the case 5 is detachable from the main body portion (the bottom plate 5a and the side plate) of the case 5. Thus, by removing the top plate 5b, the exhaust passage 9 is opened upward, and the inner wall surface of the exhaust passage 9 and the fan 11 can be easily cleaned and maintained. Further, the downstream side of the fan 11 in the exhaust passage 9 is a throttle duct portion 24 whose flow area is narrowed toward the downstream side (exhaust port 8 side), and in the exhaust direction of the exhaust from the exhaust port 8. I try to have directivity. The restrictor duct portion 24 may be provided in the case 5 as necessary (that is, it may be detachable from the portion other than the restrictor duct portion 24 of the case 5). The opening direction of the exhaust port 8 (exhaust direction of the exhaust gas) may be arbitrarily set.

  In the cassette stove 1a configured as described above, the odor and smoke generated when the cooking part 6 is baked are exhausted from the intake port 7 around the cooking part 6 into the case 5 by the fan 11. The air can be sucked into the passage 9 and removed by the filter 10, and the air coming out from the exhaust port 8 can be made to contain almost no odor or smoke. Therefore, even if the cassette stove 1a is used indoors, it is possible to prevent the odor and smoke generated when the food is baked from filling the surroundings.

  Moreover, in the cassette stove 1a of this example, the cooking unit 6 is disposed in the recess 18 recessed from the upper surface of the case 5, and the intake port 7 is located above the cooking unit 6 in the recess 18. Since it is provided over the peripheral surface of the part, it can be sucked into the exhaust passage 9 from the intake port 7 and removed by the filter 10 with almost no odor or smoke rising when the food is baked in the cooking unit 6. Therefore, the odor and smoke can be effectively removed.

  Further, since the filter 10 and the fan 11 are sequentially arranged in the exhaust passage 9 from the intake port 7 side, smoke and odor sucked into the exhaust passage 9 are removed by the filter 10 before passing through the fan 11. Therefore, adhesion of oil or the like contained in the smoke to the fan 11 can be prevented. The oil contained in the smoke adheres to the inner wall surface of the exhaust passage 9 upstream of the filter 10, but the top plate 5b of the case 5 is removed and the exhaust passage 9 is opened upward as described above. Since it can be made into the state made into the state, it is easy to clean, ie, the favorable maintainability is also ensured.
