Is discharged to the outside through Therefore, the firing chamber 3
There is no possibility that smoke spreads inside and the object to be heated M has a smoke smell. In the baking chamber 3, a plurality of heat sources 4 composed of, for example, pipe-shaped gas burners are provided below the conveyor side 2A of the conveyor 2. This heat source 4
The conveyors 2 are arranged side by side at predetermined intervals in the transport direction a along the transverse direction b of the conveyor 2, and a combustion medium is supplied through a pipe 9. The heat source 4 is not limited to a gas burner, but may be an electric one. As shown in FIG. 3, the combustion gas passage 5 is formed in a hollow structure 50 having a gate-shaped cross section by, for example, an inner wall 51 made of metal and an outer wall 52 opposed to the inner wall 51 through a predetermined space. It is composed of the space,

, The inside of the roller chain 23 as the driving unit (that is, the roller chain 23 is
(The outer side of the sintering chamber 3), and a lower space surrounded by the sintering chamber 3 is configured as the firing chamber 3. The hollow structure 50 is fixed to the inner surface of the lid 12 so that it can be moved up and down integrally with the lid 12.
The firing chamber 3 is automatically opened and closed by the vertical movement of 50. The lid 12 and the hollow structure 50
May be manually opened and closed, but by adopting an automatic opening and closing structure by the elevation drive unit 16, even if the weight of the lid 12 and the like increases due to the size increase of the pottery machine and the like. , Can respond without difficulty. As shown in FIG. 3, the lower surface of the upper side 501 of the hollow structure 50 is heated by the combustion gas G introduced into the combustion gas passage 5 to radiate far-infrared radiation heat downward. An infrared radiating section, for example, a far infrared radiating panel 7 having a corrugated cross section in the transport direction a is provided. Further, a plurality of combustion gas injection holes 54 for blowing the combustion gas G introduced into the combustion gas passage 5 into the combustion chamber 3 are formed in the upper side portion 501 of the hollow structure 50 and the far-infrared radiation panel 7. . The far-infrared ray radiating section 7 may have any shape. However, by adopting this waveform, the heat radiation area is increased, and accordingly, a sufficient amount of heat is applied to the object M from above. Granted. Above the heat sources 4, roof-type gravy avoiding covers 6 are arranged along the respective heat sources 4.
The gravy avoiding cover 6 is made of, for example, a metal plate having an inverted V-shaped cross section. (Not shown) is applied, so that a sufficient amount of heating is applied to the object to be heated M, particularly the lower surface thereof. The left and right side plates 11, 11 of the body 1
In order that the combustion state by the heat source 4 can be visually recognized,
A window hole 19 closed by a door 18 shown in FIG. 3 so as to be openable is formed. At the rear of the conveyor 2 in the conveying direction a, that is, at the side of the object to be heated, the conveyor body 2
Above the non-transport side 2B, a preheating heat source 8 such as a gas burner is provided downward, and the combustion gas from the preheat heat source 8 heats the non-transport side 2B of the conveyor 2. When the non-transport side portion 2B reaches the carry-in zone and changes to the transport side portion 2A, a sufficient heating state is achieved, so that the efficiency of firing the object to be heated M is increased. In the above configuration, as shown in FIG. 3, the combustion gas G generated from the heat source 4 heats the meat juice avoiding cover 6 in the course of ascending, and further ascends, so that the combustion gas blowing holes 221 and 221 of the conveyor 2 are heated. 221 is introduced into the combustion gas passage 5 and circulates through the combustion gas passage 5 through the firing chamber 3. The combustion gas G introduced into the combustion gas passage 5 is
The gas is blown into the combustion chamber 3 from the combustion gas blow hole 54. Further, the combustion gas G is conducted through the combustion gas passage 5, so that the far-infrared radiation panel 7 is heated, so that the far-infrared radiation panel 7 radiates far-infrared radiation heat downward. For this reason, the object to be heated M conveyed by the conveyor 2 is the combustion gas G blown from above.
Is heated directly, while it is also heated by radiant heat of far infrared rays from above. Further, by heating the meat juice avoiding cover 6, far-infrared radiation heat is radiated upward from the far-infrared radiating film on the upper surface of the meat juice avoiding cover 6.
The lower surface side is sufficiently heated by the radiant heat of far infrared rays. Therefore, the object to be heated M which is carried in from the carry-in zone I and conveyed by the conveyer 2 passes through the firing chamber 3, and the combustion gas G blown from above is blown from above.
Of the far-infrared radiation from the far-infrared radiation film on the upper surface of the far-infrared radiation panel 7 and the meat juice avoidance cover 6, the whole is uniformly heated and taken out of the carry-out zone III in a good baked state. . The gravy that has oozed out of the object to be heated M during firing is received by the bottom plate 13 below the heat source 4. Therefore, the gravy does not stay above the heat source 4 and is not abnormally burned by heating. Moreover, even if the falling meat juice hits the heat source 4, the meat juice avoiding cover 6 is disposed above the heat source 4, so that the meat juice does not adhere to the heat source 4 and becomes dirty. The possibility of hindering the combustion operation of No. 4 is also eliminated. Therefore, it can be positively used for baking and cooking the heated object M containing a lot of gravy. Further, since the combustion gas passage 5 is located on the inner side in the transverse direction b with respect to the roller chain 23 which is a driving portion of the conveyor 2, smoke generated at the time of firing the object to be heated M is generated. Adhesion to the roller chain 23 is suppressed, and the conveyance operation of the conveyor 2 is favorably maintained. This leads to relief from frequent maintenance work for the conveyor 2. By the way, the heat source 4 may be arranged along the conveying direction a. In this case, however, the meat juice avoiding cover 6 must be a long one corresponding to the entire length of the heat source 4. is there. On the other hand, when the heat source 4 is arranged along the transverse direction b of the conveyor 2 as in the above-described embodiment, the object to be heated M is normally located near the center of the conveyor 2 in the transverse direction b. It is not necessary to make the gravy avoiding cover 6 as long as the entire length of the heat source 4, and by using the short-sized gravy avoiding cover 6 corresponding to the central part, Can cope with falling. On the other hand, even when the heat source 4 is arranged along the conveying direction a, the routing portion of the heat source pipe is formed along the transverse direction b of the conveyor 2. For this reason, in addition to disposing the gravy avoiding cover 6 on the heat source 4, even if the gravy avoiding cover 6 is disposed above the piping routing portion, the gravy avoiding cover on the piping routing portion is also provided. 6 is not transferred, so that if the gravy falls on the pipe routing portion and adheres to the gravy avoiding cover 6, it will stick and remain without being dried, and it will take a considerable amount of time to remove it. It takes time and effort. On the other hand, when the heat source 4 is arranged along the transverse direction b of the conveyor 2 as in the above embodiment, the gravy is also placed on the pipe routing section along the transverse direction b. When the avoiding cover 6 is provided, since the meat avoiding cover 6 is also transferred with heat, the meat juice attached to the meat avoiding cover 6 dries and is easily removed. The conveyor 2 is of a double-sided drive system in which roller chains 23 as drive units are disposed on both sides in the transverse direction b. The roller chains 23 are provided only on one side in the transverse direction b. To the one-side drive system
Applicable. The conveyor 2 is a chain (drive unit)
The conveyor body 22 and the conveyor body 22 may not be integrated, and as shown in FIG.
It may be configured in a net-like, plate-like, or other tray type that is detachable with respect to 3. In this embodiment, the heat of the combustion gas G introduced into the combustion gas passage 5 and the radiant heat of the far-infrared radiation panel 7 are applied to the object to be heated M from above. Heat of gas G and far infrared radiation panel 7
May be configured to be heated by any one of the radiant heat of As described above, according to the present invention, the combustion gas blowing
