The upper end of the exhaust duct 7 is formed on the top plate 3 of the body 2. Connected to the exhaust port 16.
Further, an inclined surface 17 is formed at the center of the rear plate 11 forming the outlet from the grill case 6 in the left-right direction, and the inclined surface 17 is formed in the front downward direction. The inclined surface 17 penetrates the lower casing 9 from below. A temperature sensor 18 (here, a thermistor) is provided as a temperature detecting means in which the heat sensitive portion 19 is projected on the inclined surface 17. Reference numeral 20 denotes a sensor cover which is provided on the inclined surface 17 to protect the temperature sensor 18 from above and to open the front and rear to allow passage of combustion exhaust gas.

On the other hand, the bottom of the grill case 6 is provided with a support frame 21 that can be taken in and out from the front, and a grill screen 22 and a soup saucer 23 are provided on the support frame 21, respectively. It is possible to take in and out from the grill case 6 at the same time as taking it in and out.
First, as shown in FIG. 3, the support frame 21 includes a metal frame body 24 that is bent in a rectangular shape in plan view, and front support plates that are fixed to the front and rear ends of the frame body 24 in the longitudinal direction. 25 and a rear support plate 26, and a grill door 27 is attached to the front support plate 25. The support frame 21 is guided by rail-shaped support frame receivers 28, 28 (FIG. 1) provided on the left and right of the bottom of the lower casing 9 so as to be slidable in the front-rear direction.

The grilling table 22 has a frame shape formed by continuously bending metal rods, and the front and rear ends in the longitudinal direction are placed on the front support plate 25 and the rear support plate 26 of the support frame 21, respectively. At the front and rear ends in the direction, convex-shaped receiving portions 29, 29 each having a protruding central portion are formed by bending upward.
The soup tray 23 has a rectangular shape in a plan view whose dimension in the longitudinal direction is smaller than the interval between the receiving portions 29, 29 of the grill table 22, and a concave portion 30 having a rectangular shape in a plan view which is slightly smaller than the outer shape is formed in the center. Thus, a flange portion 31 that spreads outward is formed on the peripheral portion of the recess 30. The soup tray 23 is supported in a state of being placed on the grill table 22 by fitting the recess 30 into the grill table 22 and locking the flange portion 31.

Then, on the grill table 22, a grill formed in a rectangular shape in a plan view by a metal rod is locked to the left and right shoulders of the receiving portions 29, 29, respectively, at the front and rear ends in the longitudinal direction. Although it is mountable, a mounting table 32 for supporting the cooking container 50 in the grill case 6 is provided here instead of the grill.
The mounting table 32 is formed by forming a metal bar into a rectangular shape in plan view, and bends the front and rear ends in the longitudinal direction upward to form the upright portions 34, 34. A plate-like front locking plate 35 and a rear locking plate 36 connected to the upright portions 34, 34 of the lower surface support frame 33, and upper surfaces of both locking plates 35, 36, respectively. And a peripheral surface supporting frame 37 as a peripheral surface supporting portion made of the rod material.

The lower surface support frame 33 is formed such that the dimension in the left-right direction is smaller than the width dimension of the cooking container 50 described later, and the cooking container 50 can be placed. A pair of protrusions 38, 38 are formed at the front end of the front locking plate 35 and the rear end of the rear locking plate 36, and the protrusions 38, 38 are formed on both shoulders of the receiving part 29 of the grill table 22. By locking it to the part, it can be placed in the form of bridging between the front and rear receiving parts 29, 29 like the grill.
Further, at the rear edge of the rear locking plate 36, a vertical plate portion 40 that is bent downward and a horizontal plate that is bent backward from the lower end of the vertical plate portion 40 are provided between the protrusions 38, 38. The detour member 39, which has an L-shaped cross section and is formed integrally with the portion 41, is integrally formed. Further, on the left and right of the rear portion of the rear locking plate 36, cover portions 42, 42 projecting outward are formed, respectively.

The peripheral surface support frame 37 is formed along the peripheral surface of the cooking container 50. Here, the notches 43, 43 are formed on the left and right sides, and the peripheral surface support frame 37 is divided into a front frame portion 44 and a rear frame portion 45. It has a shape. Since both the left and right ends of both frame portions 44 and 45 are curved according to the end shape of the cooking container 50, when the cooking container 50 is placed on the lower surface support frame 33, both frame portions 44 and 45 are formed. Are fitted to the front and rear of the cooking container 50 so that the cooking container 50 can be positioned in the front, back, left and right.

The cooking container 50 includes a box-shaped container body 51 having an open upper surface, and a lid 52 that closes the opening of the container body 51. The container main body 51 has a rectangular shape in plan view having four corners of an R shape and a bottom surface of a corrugated shape, and ears 53, 53 project from both sides in the longitudinal direction. A long through hole 54 is formed in each of the ears 53 in the front-rear direction. By locking a handle (not shown) to the ear portion 53 and the through hole 54, the cooking container 50 can be taken in and out.
The lid body 52 has a shape similar to that of the container body 51 in plan view and is one size smaller than the container body 51 and has a shallow box shape with an opening on the lower surface, and a vapor discharge hole 55 is formed on the upper surface. .. Both the container main body 51 and the lid 52 are made of iron.

In the built-in stove 1 configured as described above, the grilling table 22 is first placed on the support frame 21 pulled out from the grill case 6 in alignment with the positioning recesses (not shown) provided on the front and rear support plates 25 and 26. After that, the soup tray 23 is placed above it so that the recess 30 is fitted between the receiving portions 29, 29 to the grill table 22. Then, as shown in FIG. 3, the juice tray 30 is set on the support frame 21 in a state where movement is restricted in the front, rear, left, and right directions.
Next, the mounting table 32 is locked by the projections 38, 38 of the front and rear locking plates 35, 36 on the shoulders of the receiving portions 29, 29, respectively. Supported horizontally.

Then, if the cooking container 50 containing the food to be cooked is placed on the lower surface support frame 33 of the mounting table 32 between the peripheral surface support frames 37, the cooking container 50 is placed on the mounting table 32 as shown in FIG. And is supported horizontally above the support frame 21 via the grilling table 22.
When the support frame 21 with the cooking container 50 set in this way is housed in the grill case 6, the cooking container 50 is supported at a height located between the upper and lower burners 10, 12, as shown in FIGS. become. In this state, in the detour member 39 of the rear locking plate 36, the vertical plate portion 40 is located in front of the inclined surface 17 of the exhaust duct 7 in front view and crosses the front of the temperature sensor 18, and the horizontal plate portion 41 is the inclined surface. It is close to the front end at a height substantially matching the front end of 17. Further, the left and right cover portions 42, 42 are positioned slightly rearward of the thermocouples 14, 14 provided on the lower burners 12, 12 and project to the upper side.

At this time, the mounting table 32 extends forward and backward longer than the arrangement range (W shown in FIG. 1) of the flame openings 13, 13,... Of the lower burner 12, and serves as a central portion on which the cooking container 50 is mounted. Only the lower surface support frame 33 faces the array range W.
Further, the peripheral surface support frame 37 has a front frame portion 44 and a rear frame portion 45 separated before and after the arrangement range W, and the notches 43, 43 are opposed to the arrangement range W. Therefore, the left and right side surfaces of the container body 51 of the cooking container 50 face the arrangement range W of the flame nozzles 13 without any intervening therebetween.

Here, when the fire extinguisher button for the grill provided on the front panel is pressed, the gas passages to the upper and lower burners 10 and 12 are opened to supply the fuel gas, and the controller (not shown) activates the ignition electrode. The upper and lower burners 10 and 12 are burnt. Therefore, the cooking container 50 is heated from above and below by the flames of the upper and lower burners 10 and 12, and the food to be cooked inside is cooked.
Then, the combustion exhaust gas generated from the upper and lower burners 10 and 12 moves to the rear portion of the grill case 6 and is discharged from the exhaust port 16 through the exhaust duct 7. At this time, the controller can execute the overheat prevention function of monitoring the detected temperature obtained from the temperature sensor 18 provided in the exhaust duct 7 and stopping the combustion of the upper and lower burners 10 and 12 when the temperature reaches a predetermined temperature. ..

In this case, the combustion exhaust from the lower burner 12 tries to enter the exhaust duct 7 from below the rear locking plate 36 of the mounting table 32, as shown by the dotted arrow in FIG. However, since the bypass member 39 is formed at the rear end of the rear locking plate 36, the combustion exhaust gas comes into contact with the vertical plate portion 40 of the bypass member 39 and is divided into right and left as shown by a dotted arrow in FIG. , And enters the exhaust duct 7 from the left and right in such a manner as to go around the bypass member 39. Therefore, the combustion exhaust does not flow directly toward the heat-sensitive portion 19 of the temperature sensor 18 on the inclined surface 17, and the rise in the temperature detected by the temperature sensor 18 is suppressed in a short time. , 12 is no longer stopped.

In particular, since the detour member 39 is also provided with the horizontal plate portion 41, it becomes difficult for the combustion exhaust gas to flow under the vertical plate portion 40, and the direct flow to the temperature sensor 18 is more effectively restricted. Further, since the rear locking plate 36 is provided so as to close the rear of the cooking container 50 and the bypass member 39 is provided at the rear end thereof, the rear locking plate 36 prevents the combustion exhaust gas from rising from the lower burner 12. It is easily blocked and comes into contact with the detour member 39. Therefore, the effect of inducing the combustion exhaust gas by the bypass member 39 is effectively exhibited.

On the other hand, the controller monitors the thermoelectromotive force of the thermocouples 14 and 14 heated by the combustion exhaust from the lower burner 12 to detect the extinction, but here, the combustion exhaust flowing backward is the thermocouple 14. After passing through, before contacting the exhaust duct 7, it abuts the cover portion 42 provided on the rear locking plate 36 of the mounting table 32 to block the flow, and temporarily stays below the rear locking plate 36. To the exhaust duct 7. Therefore, the thermocouple 14 is reliably heated by the combustion exhaust gas staying here, and the disappearance can be detected accurately.

As described above, according to the built-in stove 1 of the above-described embodiment, the combustion exhaust gas generated in the grill case 6 is located in the rear part of the mounting table 32 and in front of the temperature sensor 18 while being supported by the receiving parts 29, 29. By providing the detour member 39 that prevents the temperature from directly flowing to the temperature sensor 18, it is possible to suppress an increase in the detected temperature of the temperature sensor 18 in a short time. Therefore, even when the cooking container 50 is used in the existing grill 5, the combustion is not stopped during the heating and cooking, and the usability is not impaired.

In particular, here, the detour member 39 includes the vertical plate portion 40 that is bent downward from the rear locking plate 36 of the mounting table 32, and therefore the lower burner 12 that heats the lower space of the cooking container 50 is used. It is possible to guide the flow of the combustion exhaust gas generated in the horizontal direction, and to more effectively prevent the direct flow to the temperature sensor 18.
Further, at the lower end of the vertical plate portion 40, a horizontal plate portion 41 that projects rearward and is close to the inner surface of the rear portion of the grill case 6 is formed in a bent shape, so that the combustion exhaust gas is prevented from flowing under the vertical plate portion 40. This can be effectively prevented, and the combustion exhaust can be reliably guided to the left and right of the vertical plate portion 40.

Further, the placing table 32 is formed such that the dimension in the front-rear direction is longer than the arrangement range W of the flame nozzles 13, and the cooking container 50 is placed while being supported by the receiving portions 29, 29. Since the lower surface support frame 33 faces the arrangement range W, the cooking container 50 can be supported at the optimum position suitable for cooking.
In addition, the mounting table 32 is provided along the peripheral surface of the cooking container 50 and is provided along the peripheral surface support frame 37 for positioning the cooking container 50 in the front, rear, left and right, and the lower surface of the cooking container 50 for cooking. Since the container 50 is formed by the lower surface support frame 33 that supports the container 50 from below, and the peripheral surface support frame 37 is provided with the notch 43 at a portion facing the arrangement range W, the flame from the lower burner 12 is surrounded by the peripheral surface. The cooking vessel 50 can be directly heated without being cooled by the support frame 37. Therefore, efficient cooking can be performed using the mounting table 32.

Note that the structure of the bypass member is not limited to the above-mentioned form, and can be appropriately changed as long as it can prevent the flow of the combustion exhaust gas directly to the temperature sensor. For example, in the above embodiment, the bypass member is formed of the vertical plate portion and the horizontal plate portion, but the horizontal plate portion may be omitted and only the vertical plate portion may be formed. In this case, it is possible to increase the vertical width of the vertical plate portion, or to make the vertical width unequal over the entire length in the left-right direction, and to form a downward semicircle or trapezoid in which the central portion facing the temperature sensor extends downward. You can also The cross-sectional shape is not limited to the L shape, but may be an arc shape or a linear shape.
Further, the detour member is not limited to the structure in which the detour member is formed integrally with the mounting table, and the detour member formed separately may be attached to the mounting table afterwards with screws or the like.
Furthermore, the temperature sensor is also installed at a position rearward of the boundary between the grill and the exhaust duct in the above-described embodiment. It may be provided, or may be provided near the exit at the exit itself (boundary).

On the other hand, the structure for supporting the mounting table is not limited to the support frame and the grill table of the above-described embodiment, and the one in which the grill portion is directly provided on the support frame or the saucer integrated with the support frame The supporting structure of the placing table can be appropriately changed as long as it has a receiving portion capable of selectively supporting the grill and the placing table, such as one on which the grilling table is placed.
The structure of the mounting table itself can be made only of metal rods like a grill table (in this case, the detour member will be attached later), or the front and rear integrated locking plates can be cooked without the peripheral support frame. It is also possible to form a through hole into which the container fits. The cooking container is not limited to the rectangular shape in the plan view, and may have any other shape such as an oval shape or a circular shape in the plan view as long as the cooking container can be supported in the grill chamber via the mounting table.
In addition, in the above embodiment, the built-in stove with a grill is described, but the present invention can be applied to a table stove with a grill.
