  In FIG. 11, the bent portion 51 b 1 is provided to be inclined to the front side, but in particular, the angle may be provided at a right angle or according to the angle of the side surface of the grill pan 60.

  In addition, linear portions 51f and 51f are formed at the front ends of the linear portions 51a and 51a, which are bent inward in the width direction and inserted into holes 31a and 31a formed at the front ends of the door joint 31. Thereby, the grill pan stay 50 is prevented from being displaced on the slide bar 30.

  The grill pan (deep dish) 60 is made of, for example, a material such as aluminum or ceramic, and the surface thereof is coated with a fluorine coating agent or the like. The grill pan 60 includes a bottom plate 60a having a substantially square shape and a side plate 60b that rises upward from the outer peripheral edge of the bottom plate 60a. The grill pan 60 is configured to have a concave shape, for example, fish (for example, sword fish). It has a space (capacity) that can be placed side by side with the head and tail facing forward and backward. Thus, by using the deep dish-shaped grill pan 60, oil splashing during cooking can be suppressed, and dirt in the cooking cabinet Q can be suppressed.

  On the bottom plate 60a, a plurality of ridges 60c extending in the width direction (left-right direction) are formed at intervals in the front-rear direction. A flange 60e that is bent outward is formed on the upper end 60d of the side plate 60b, so that the grill pan 60 can be easily handled and the grill pan 60 can be easily carried.

The rear temperature sensor 100 is connected to the control unit (not shown), and is controlled by the control unit according to the temperature input detected by the rear temperature sensor 100.

  FIG. 5 shows a state in which the slide bar is fixed to the door joint, where (a) is a side view, (b) is a bottom view, and (c) is a rear view. As shown to Fig.5 (a), the slide bar 30 is comprised by bending one iron wire. The slide bar 30 includes a straight portion 30a (upper straight portion) and a straight portion 30b (lower straight portion) extending in the front-rear direction in the vertical direction, and a U-shaped portion 30c (in a U-shape extending at the rear end). Connecting portion). The straight portions 30a and 30b are arranged in parallel to each other. Moreover, the slide bar 30 is comprised by giving chrome plating to the surface of a wire, for example. In addition, the diameter φ of the slide bar 30 is set to 6 mm. Further, the U-shaped portion 30c of the slide bar 30 is set to be bent R = 12 mm, for example. This bend R is set to the minimum that can be processed.

  As shown in FIG. 5B, the slide bar 30 has a fixed portion 30d whose front end is bent at a right angle inside the width direction (left-right direction). That is, the fixed portion 30d extends in a direction (left-right direction) orthogonal to the direction (front-rear direction) of the straight portion 30a. In addition, the fixed part 30d (refer FIG.5 (c)) is comprised also about the linear part 30b similarly to the above.

  The door joint 31 extends in the width direction, and is formed with a connecting plate 31b that abuts and fixes the fixing portions 30d and 30d of the left and right slide bars 30 and 30. Fixing portions 30d and 30d are fixed to the left and right ends of the connecting plate 31b.

  As shown in FIG.5 (c), the door coupling 31 has the holding | maintenance part 31c which hold | maintains the front end of linear part 30a, 30b. The holding portion 31c includes a side surface contact portion 31c1 with which the outer surfaces of the straight portions 30a and 30b abut, an upper surface contact portion 31c2 with which the upper surface of the straight portion 30a contacts, and a lower surface contact with which the lower surface of the linear portion 30a contacts. A contact portion 31c3. By forming such a holding portion 31c, when the slide bar 30 is fixed to the door joint 31, the slide bar 30 can be easily positioned in the left-right direction and the up-down direction.

  In the present embodiment, the fixed portions 30d and 30d of the slide bar 30 and the straight portions 30a and 30b are arranged in an orthogonal direction. Thereby, when the left and right slide bars 30, 30 are fixed to the connecting plate 31 b of the door joint 31, the parallelism between the left and right slide bars 30, 30 can be increased (a shake in the left-right direction can be prevented). That is, in the left and right slide bars 30 and 30, the separation distance S1 (see FIG. 5B) at the front part and the separation distance S2 (see FIG. 5B) at the rear part can be made uniform. Moreover, since the slide bar 30 is composed of two straight portions 30a and 30b in the vertical direction, the vertical swing of the slide bar 30 can be prevented. As a result, since the frictional resistance between the slide bar 30 and the guide rail 40 can be reduced, noise when the slide bar 30 slides in the guide rail 40 can be reduced.

  FIG. 6A is a perspective view of the state where the slide bar is pulled out partway from the guide member, and FIG. 6B is a plan view of the state where the slide bar is housed in the guide member. In FIG. 6, the left and right slide bars 30, 30 and the guide rails 40, 40 are symmetrical, so only the right slide bar 30 and the guide rail 40 will be described, and description of the left side will be omitted.

  As shown in FIG. 6A, the guide rail 40 is formed with a screw hole 40a through which a screw 45 is inserted at a front side in the front-rear direction, and a screw 45 (fixing member) is screwed into the screw hole 40a. It has become so. Moreover, the guide rail 40 is comprised by bending and forming the board | plate material made from a stainless alloy in substantially C shape in a cross sectional view. That is, the guide rail 40 has an inner plate part 42 a located on the inner side (left side) from the slide bar 30, an upper plate part 42 b located above the slide bar 30, and a lower position located below the slide bar 30. A plate portion 42c; an outer upper plate portion 42d positioned on the outer surface side of the linear portion 30a of the slide bar 30; and an outer lower plate portion 42e positioned on the outer surface side of the linear portion 30b of the slide bar 30. ing.

  As shown in FIG. 6B, the guide rail 40 extends in the front-rear direction and is shorter than the slide bar 30 in the front-rear direction. That is, the guide rail 40 includes a rear portion including the U-shaped portion 30c of the slide bar 30 with the fixed portion 30d of the slide bar 30 protruding forward from the front end portion 40b of the guide rail 40 when the door 20 (see FIG. 3) is fully closed. Protrudes rearward from the rear end portion 40 c of the guide rail 40.

  The guide rail 40 is provided with a contact member 41 that contacts the slide bar 30. The contact member 41 is formed at a position overlapping with the screw hole 40a in the vertical direction, and is elongated in the front-rear direction. Further, the contact member 41 is arranged offset from the center G in the width direction (left-right direction) of the guide rail 40 to the inside in the width direction (left-right direction). The contact member 41 is made of, for example, a synthetic resin excellent in heat resistance, slidability, and wear resistance. Specifically, a PPS (polyphenylene sulfide) resin can be selected.

  FIG. 7A is a cross-sectional view taken along line BB in FIG. 6B, and FIG. 7B is a cross-sectional view when the slide bar is pulled out to the maximum from the guide member.

  As shown in FIG. 7A, the inner height dimension H <b> 2 of the guide rail 40 is larger (higher) than the height dimension H <b> 1 of the slide bar 30. Further, the width dimension W2 inside the guide rail 40 is formed larger (wider) than the width dimension W1 of the slide bar 30. Thereby, the sliding property when the slide bar 30 moves back and forth in the guide rail 40 is improved, and generation of noise can be prevented.

  Further, the corner portion of the boundary between the inner plate portion 42a and the upper plate portion 42b, the corner portion of the boundary between the upper plate portion 42b and the outer upper plate portion 42d, and the corner portion of the boundary between the inner plate portion 42a and the lower plate portion 42c. The corner portions of the boundary between the lower plate portion 42c and the outer lower plate portion 42e each have an R shape.

  Further, the straight portions 30a and 30b of the slide bar 30 have a circular shape in a cross-sectional view. Although not shown, the U-shaped portion 30c also has a circular shape in sectional view. Thereby, the contact between the straight portions 30a and 30b and the inner plate portion 42a, the contact between the straight portions 30a and 30b and the upper plate portion 42b, the contact between the straight portions 30a and 30b and the lower plate portion 42c, and the straight portions 30a and 30b. And the contact between the outer upper plate portion 42d and the contact between the straight portions 30a and 30b and the outer lower plate portion 42e can be made into line contact. Therefore, the contact resistance between the straight portions 30a and 30b and the guide rail 40 can be reduced, and noise when the slide bar 30 slides on the guide rail 40 can be prevented.

  Further, as described above, by setting the bending R of the U-shaped portion 30c to the minimum, the cross-sectional area of the area Z inside the guide rail 40 through which the slide bar 30 passes can be reduced, so that the section Z escapes from this area Z. Can reduce hot air.

  The contact member 41 is attached by being inserted into a notch 41a formed at a corner between the inner plate portion 42a and the upper plate portion 42b of the guide rail 40. That is, the contact member 41 is formed in a substantially U shape in a cross-sectional view, and is positioned on the outside of the upper plate portion 42b of the guide rail 40 and on the inner side of the upper plate portion 42b of the guide rail 40. Extending part 43b.

  The extending portion 43a is formed with a protruding portion 43c that sandwiches the upper plate portion 42b with the extending portion 43b. The extension part 43b is formed longer than half (1/2) of the width dimension W2 inside the guide rail 40. In other words, even when the slide bar 30 moves to the rightmost side, the upper end portion of the linear portion 30a comes into contact. Further, the lower surface 43b1 of the extending portion 43b is a horizontal surface.

  Further, since the guide rail 40 is fixed to the side plate 11b of the base 11, the contact member 41 can be prevented from falling off from the notch 41a.

  As shown in FIG. 7B, when the slide bar 30 is pulled out from the guide rail 40, the inner peripheral side of the U-shaped portion 30 c of the slide bar 30 comes into contact with the screw 45 so that the slide bar 30 is pulled out. Being regulated. Thus, the screw 45 has a function of fixing the guide rail 40 to the base 11 and a function as a stopper of the slide bar 30.

  Further, as the slide bar 30 is pulled out from the guide rail 40, the amount of inclination (the amount of inclination of the grill pan 60) by which the slide bar 30 is inclined due to the weight of the door 20 increases (increases). In the present embodiment, the contact member 41 is provided at a position overlapping the screw 45 in the vertical direction, so that when the slide bar 30 is pulled out to the maximum, the rear end upper portion 30s of the slide bar 30 is moved by the contact member 41. Since the slide bar 30 is pushed downward, the amount of inclination of the slide bar 30 can be reduced. Therefore, the amount by which the grill pan 60 tilts can be reduced, and usability when cooking with the grill pan 60 can be improved.

  8A and 8B show a door click mechanism. FIG. 8A is an explanatory view showing a positional relationship between the door and the frame portion before closing the door and a positional relationship between the slide bar and the tilt suppressing member. FIG. It is explanatory drawing which shows the positional relationship of a door and a frame part when closed, and the positional relationship of a slide bar and an inclination suppression member. As shown in FIG. 8A, the door 20 is formed with a tongue 24 extending toward the frame 13 side. The tongue 24 is inserted with an insertion hole 13 c formed below the opening 13 a of the frame 13.

  On the lower surface of the tongue 24, a taper 24a that descends from the back side (the frame 13 side) toward the near side is formed. Further, a recessed portion 24b having a concave surface formed downward is formed behind the taper 24a of the tongue portion 24. The height of the recess 24b on the ceiling side is formed higher than the height of the lowermost portion 24a1 of the taper 24a.

  Further, before the door 20 shown in FIG. 8A is closed, the lower edge 13c1 of the insertion hole 13c is formed at a position higher than the lowermost part 24a1 of the taper 24a, and the upper surface of the lower edge 13c1 and the lowermost part 24a1 Is set to S10.

  On the other hand, the slide bar 30 is inclined so that the front part of the slide bar 30 is bowed by the dead weight of the door 20 before the door 20 shown in FIG. Is in contact with the lower plate portion 42c. Further, a gap S <b> 20 is formed between the linear portion 30 a of the slide bar 30 and the contact member 41.

  The relationship between the difference S10 and the gap S20 is set as S10> S20. For example, S10 is 1 mm and S20 is 0.5 mm.

    When the tongue 24 is inserted into the insertion hole 13c from the state shown in FIG. 8A, the door 20 is lifted by the taper 24a sliding on the lower edge 13c1 of the insertion hole 13c. As for the slide bar 30, as the taper 24 a moves while sliding on the lower edge 13 c 1, the linear portion 30 a comes into contact with the contact member 41 from the state where the linear portion 30 a is separated from the contact member 41. Lift to be. At this time, in order for the tongue portion 24 to ride on the lower edge 13c1, it is necessary to lift the tongue portion 24 by the height of the difference S10, but the slide bar 30 can only lift the gap S20. Therefore, as the tongue 24 is inserted into the insertion hole 13c, the slide bar 30 is bent, and thus the slide bar 30 generates a restoring force that restores the bending force of the slide bar 30. Then, after the tongue portion 24 rides on the lower edge 13c1, as shown in FIG. 7 (b), the depression portion 24b falls into the lower edge 13c1 so that a click feeling can be given to the door 20. Thereby, the user can recognize that the door 20 is closed, and can prevent cooking (heating) from being started in a state where the door 20 is opened halfway.

  Further, in the state where the door 20 shown in FIG. 8B is closed, the downward force F1 is applied to the linear portion 30a of the slide bar 30 by the contact member 41, so that the downward force is applied to the door 20 as well. F2 is acting. Thereby, since the hollow part 22b is pressed against the lower edge 13c1, it can prevent that the door 20 opens during cooking by vibration etc.

  FIG. 9A is a front view showing the opening of the door, and FIG. 9B is a perspective view when looking into the opening of the door obliquely from above. 9A and 9B illustrate a state where the glass plate 23 is removed from the door 20.

  As shown in FIG. 9A, the door 20 includes a door base 21, a handle 22, and a glass plate 23 (see FIG. 8A). The door base 21 is formed by pressing a sheet metal or the like, and has a horizontally long rectangular opening 21a. The opening 21a has a smaller opening area than the conventional one. Thus, heat radiation can be reduced by reducing the opening 21a.

  The handle 22 is made of synthetic resin and is disposed at the lower part of the door 20. The glass plate 23 is comprised with the tempered glass, and is arrange | positioned ahead including the opening part 21a (refer Fig.8 (a)). Further, in the glass plate 23, the horizontally long rectangular region Q1 (see FIG. 2) corresponding to the opening 21a has a transparent color, and the surrounding region Q2 (see FIG. 2) has a black color. Moreover, the temperature of the handle | steering-wheel 22 can be suppressed by making the opening part 21a small and reducing heat dissipation as mentioned above.

  As shown in FIG. 9A, when the door 20 is viewed from the front, the upper end 21a1 of the opening 21a is positioned above the grill pan 60 (upper end 60d). As a result, as shown in FIG. 9B, the inside of the grill pan 60 can be visually recognized when the opening 21a is looked into obliquely from above. Thereby, during cooking, the heating state of the heated object in the grill pan 60 can be confirmed without opening the door 20.

  FIG. 10 is a cross-sectional view showing a temperature sensor that detects the temperature of the grill pan. As shown in FIG. 10, the sensor cover 71 has a truncated cone shape (Mt. Fuji shape), and is configured by drawing a sheet metal. Further, the top of the sensor cover 71 has a circular flat portion 71a.

  The sensor part 72 is formed in a substantially T-shape in cross section, and includes a circular part 72a whose tip (upper end) is in surface contact with the lower surface (back surface) of the flat part 71a. The circular part 72 a has a larger diameter than the base part 72 b of the sensor part 72.

  The sensor plate 73 has a ring shape that is inserted into the base portion 72 b of the sensor portion 72, and the circular portion 72 a of the sensor portion 72 is sandwiched between the sensor plate 73 and the sensor cover 71.

  The sensor holding member 74 is interposed between a holding metal fitting 74a that protrudes into the sensor cover 71, and the sensor plate 73 and the holding metal piece 74a, so that the circular portion 72a of the sensor portion 72 is replaced with the sensor cover 71 (flat surface portion 71a). ) And a compression coil spring 74b that is pressed against. The holding metal fitting 74a has a mountain shape in cross section, and a concave portion 74c is formed on the top for accommodating and holding a part of the compression coil spring 74b.

  In the temperature sensor 70 configured as described above, the sensor cover 71 and the holding metal fitting 74a are fixed to the bottom plate 11a (see FIG. 3) via screws 75 and 75.

  11A is before the grill pan stay gets over the temperature sensor, FIG. 11B is while the grill pan stay gets over the temperature sensor, and FIG. 11C is after the grill pan stay gets over the temperature sensor. As shown in FIG. 11A, before the door 20 (see FIG. 2) is fully closed, the linear portion 51c (the rearmost linear portion 51c) of the grill pan stay 50 that supports the grill pan 60 is first a sensor. It contacts (buts against) the slope 71b of the cover 71. At this time, the linear portion 51d located behind the linear portion 51c passes through a position higher than the sensor cover 71, and therefore does not contact the sensor cover 71. Further, the bent portion 51b1 of the linear portion 51b located behind the linear portion 51d passes through a position higher than the sensor cover 71, and therefore does not contact the sensor cover 71. Therefore, the linear part 51c hits the sensor cover 71 first. At this time, since the linear portion 51 c is located between the grill pan 60 and the inclined surface 71 b of the sensor cover 71 in the moving direction (front-rear direction) of the grill pan 60, the grill pan 60 does not hit the sensor cover 71.

  When the door 20 is further pushed from the state shown in FIG. 11 (a), the linear part 51c of the grill pan stay 50 rises while sliding on the slope 71b, and as shown in FIG. 11 (b), the linear part 51c rides on the flat surface 71a. At this time, the grill pan 60 is supported by the linear portion 51c, and the bottom surface 60s of the grill pan 60 is located higher than the flat portion 71a, so that the grill pan 60 does not contact the sensor cover 71.

  When the door 20 is further pushed from the state shown in FIG. 11B, the linear portion 51c of the grill pan stay 50 moves backward while sliding on the flat portion 71a, as shown in FIG. 11C. Furthermore, the linear part 51c moves while sliding from the flat part 71a to the rear slope 71c. At this time, the bottom surface 60s of the grill pan 60 comes into surface contact with the flat surface portion 71a by the linear portion 51c descending toward the inclined surface 71c.

  As described above, when the grill pan 60 is stored, the grill pan stay 50 (the linear portion 51c) abuts against the sensor cover 71 before the grill pan 60, so that the surface of the grill pan 60 can be prevented from being worn by an impact. .

  By the way, a fluororesin is applied to the grill pan 60 to prevent burning, and it is known that such a fluororesin generates a thermal decomposition product in a high temperature environment. In the present embodiment, since the temperature sensor 70 can be brought into direct contact with the grill pan 60, the temperature of the grill pan 60 can be detected with high accuracy, air baking can be prevented, and temperature control can be performed quickly when the temperature is abnormal.

  Further, in the grill pan 60, the temperature difference becomes large between the place where the object to be heated (cooked food) is present and the place where the object is not heated. For this reason, when the temperature sensor 70 is arranged in the center where the object to be heated is frequently placed, a correlation must be taken, and it becomes difficult to accurately detect the temperature of the grill pan 60. In the present embodiment, the temperature sensor 70 is disposed at the rear of the grill pan 60 where an object to be heated is not frequently placed, so that the temperature of the grill pan 60 can be accurately detected.

  FIG. 12 is a longitudinal sectional view showing a state in which the door of the grill unit is closed. In FIG. 12, the lower heater 15 and the upper heater 16 are not shown.

  As shown in FIG. 12, when the door 20 is closed (fully closed), the rear portion of the slide bar 30 projects rearward from the position of the back plate 11 c of the base 11. Thus, the protrusion amount (protrusion length) L1 of the slide bar 30 protruding rearward from the base 11 can be made shorter than that of the conventional slide-type rail provided with the ball bearing.

  Next, the flow of air in the cooking chamber Q will be described.

  When the grill pan 60 is attached to the cooking chamber Q, the rear side of the grill pan 60 is higher than the door 20 side because the bottom surface 60s of the grill pan 60 is placed on the temperature sensor 70. Therefore, the air below the grill pan 60 is heated by the heating means and flows backward so as to stroke the bottom surface 60s of the grill pan 60 when it rises. And the air which flowed back raises the space between the backplate 11c of the base 11, and the grill pan 60, and is exhausted from the exhaust duct 14 provided in the top plate 12 through the exhaust port 8a.

  The air is caused to flow rearward so as to stroke the bottom surface 60s of the grill pan 60, so that the air is heated by the temperature of the bottom surface 60s of the grill pan 60, and the air rising in the space between the back plate 11c and the grill pan 60 (hot air) N1) is in a state with little temperature unevenness. Therefore, as shown in FIG. 12, the rear temperature sensor 100 provided on the back plate 11c of the base 11 can stably detect the temperature of the hot air N1 with little temperature unevenness. Further, the hot air N1 that has flowed backward so as to boil the bottom surface 60s of the grill pan 60 has a structure that adversely affects the flow of the hot air N1 and the temperature of the hot air N1 until it flows to the rear temperature sensor 100. For example, since there is no bent portion 51b1 (linear portion) holding the grill pan 60, the rear temperature sensor 100 can stably detect the temperature of the grill pan 60 by the hot air N1. Regarding the flow of the hot air N1 on the leeward side of the rear temperature sensor 100, it is preferable that there is no obstructive structure in the flow path.

  FIG. 13 is a longitudinal sectional view showing a state where the door of the grill unit is opened.

  As shown in FIG. 13, when the door 20 is fully opened, the entire grill pan 60 can be pulled out to the front of the heating base 10. Thereby, it becomes easy to lift the grill pan 60 directly upward, and it is possible to prevent the moisture and oil components from the heated object accumulated on the bottom of the grill pan 60 from being spilled out when the grill pan 60 is taken out.

  By the way, when the main body 2 (see FIG. 1) including the grill unit 4 is dropped from a hole (not shown) in the top plate 1a on the upper surface of the system kitchen 1 (see FIG. 1), the grill unit is removed with the door 20 removed. 4 is installed so that the front side is obliquely downward. For example, when the grill unit 4 is put in and out of the system kitchen 1 many times, it is necessary to drop it from the hole (not shown) of the top plate 1a many times. For this reason, every time the grill unit 4 is put in and out, the slide bar 30 jumps forward from the heating base 10, and the replacement work becomes complicated.

  Therefore, in the present embodiment, as shown in FIGS. 14A and 14B, in the main body 2, a gripping member (catcher) 80 that holds and holds the slide bar 30 is provided behind the slide bar 30. The slide bar 30 is prevented from popping out when the main body 2 is installed.

  That is, as shown in FIG. 14A, the gripping member 80 is positioned on the left and right sides of the slide bar 30 and is formed with a pair of curved portions 81 a and 81 a that are curved toward each other toward the slide bar 30. . The pair of curved portions 81a is formed of a plate material that can be bent and deformed in the left-right direction, and is fixed to a housing (sheet metal) of the main body 2.

  As shown in FIG. 14 (b), the curved portions 81 a and 81 a of the gripping member 80 are formed in a band shape so as to be positioned between the straight portion 30 a and the straight portion 30 b of the slide bar 30, and the rear of the slide bar 30. From the front to the front. The U-shaped portion 30c of the slide bar 30 is held by the convex portions of the pair of curved portions 81a.

  Thereby, even if the slide bar 30 (grill pan 60) has an obliquely downward angle, the slide bar 30 is held by the gripping member 80, so that the slide bar 30 can be prevented from popping out. The gripping member 80 may be provided only on the slide bar 30 on one side or on the slide bar 30 on both sides.

  FIG. 15 shows the grill operation unit 5 g of the grill unit 4 in the operation unit 5.

  Reference numeral 5g1 denotes a menu key for selecting a menu, and reference numeral 5g2 denotes a menu category display which is displayed every time the menu key 5g1 is pressed. The menu category display 5g2 includes a round display 5g3 indicating a menu for round baking, a manual display 5g4 indicating manual cooking, and the like. 5g9 is a cut start key for instructing start / stop of cooking. 5g5 is a fire / finish key, and includes a down key 5g6 and a raise key 5g7. By operating the thermal power / finishing key 5g5, the thermal power / finishing display 5g8 is displayed. The thermal power / finishing key 5g5 is used to select either strong, medium, or weak for manual cooking, and select either strong, medium, or weak for the baked color finish when automatically cooking by roasting. And so on.

  When manual cooking is performed by selecting the manual display 5g4 with the menu key 5g1, when the heating power setting is middle, the upper heater 16 is about 600W and the lower heater 15 is about 320W, and when the heating power setting is strong, the upper heater 16 When the heating power setting is weak, the upper heater 16 is about 480 W and the lower heater 15 is about 256 W. Since the object to be heated is placed on the grill pan 60 and heated, the grill pan 60 is also heated when the object to be heated is heated by the upper heater 16 from above.

  Since the heat of the grill pan 60 is received from the bottom surface where the heated object mainly contacts, the lower heater 15 has a smaller heating power than the upper heater 16.

  The present embodiment is configured as described above. Next, the operation will be described by taking as an example a case where the sword fish is grilled as an object to be heated by automatic cooking.

  Four sword fishes are arranged on the grill pan 60, the display 5g3 is selected with the menu key 5g1 of the operation unit 5, and the cooking start operation is performed with the cut start key 5g9. The cooking chamber Q starts heating by a plurality of heating process operations in which the upper heater 16 and the lower heater 15 are incorporated in advance in a control unit (not shown). In the automatic cooking round roasting, the cooking time is adjusted by controlling the amount of the object to be heated during the process. The temperature detected by the rear temperature sensor 100 is taken into the control unit a few minutes after the start, and then the temperature is measured again after a predetermined time, and the amount of the object to be heated is determined by the temperature rise during the predetermined time.

  If the measured temperature rise value is larger than the temperature rise value incorporated in advance with cooking of three sword fish as a standard, the amount is determined to be small, and if the measured temperature rise value is small, the amount is determined to be large.

  When it is determined that the amount is small, cooking is completed by shortening the cooking time of each process incorporated in advance by the same amount according to the small amount. Conversely, as in the case of the four animals shown here, when it is determined that there are many, the cooking time of each process incorporated in advance is increased by the same amount according to the large amount, and the cooking is completed. To do.

  The temperature detected by the rear temperature sensor 100 provided on the back plate 11c of the base 11 of the cooking chamber Q is a narrow space sandwiched between the side plate 60b on the rear side of the grill pan 60 and the back plate 11c of the base 11 having a stable heat capacity. Detect temperature. Further, since the bent portion 51b1 of the grill pan stay 50 is provided above the rear temperature sensor 100, the linear portion 51b of the grill pan stay 50 is located above the linear portion 51b around the lower side of the rear temperature sensor 100. Since the bent portion 51b1 provided on the front side does not exist, the flow of the hot air N1 around the rear temperature sensor 100 is not hindered, so that the rear temperature sensor 100 can stably detect the ambient temperature. Therefore, since the temperature in the cooking chamber 26 can be accurately measured, the amount can be correctly determined. Eventually, the cooking ends when all the heating steps are completed. Remove the baked sword fish from the grill pan 60.

  As described above, in the grill unit 4 (heating cooker) of the present embodiment, the casing (base 11, top plate 12, and frame 13) having the opening 13a on the front surface, and the door 20 that closes the opening 13a of the casing. And a pair of left and right slide bars 30 and 30 for sliding the door 20 in the front-rear direction, and guide rails 40 and 40 for slidably supporting the slide bars 30 and 30, and the slide bar 30 is spaced apart in the vertical direction. A straight portion 30a and a straight portion 30b extending in the front-rear direction, and a U-shaped portion 30c connecting the straight portion 30a and the straight portion 30b at the rear end in the front-rear direction. According to this, since it is not necessary to use a slide-type rail provided with a ball bearing, the slide mechanism can be configured at low cost. In addition, in the present embodiment, the slide bar 30 has a simple structure including the two straight portions 30a and 30b and the U-shaped portion 30c, so that the entire slide bar 30 can be pulled out largely toward the front. For example, the slide bar 30 can be pulled out to such an extent that the grill pan 60 can be lifted almost directly above.

  In this embodiment, since the slide bar 30 is composed of the straight portions 30a and 30b and the U-shaped portion 30c, when the door 20 is pulled out, an axial force (tensile stress) is applied to the straight portion 30a. Sb) acts, and a force (bending stress Sa) in a direction orthogonal to the axial direction acts on the straight portion 30b (see FIG. 7B). The slide bar 30 having such a shape (bar shape) is more resistant to the force in the extending direction than the direction in which the slide bar 30 is bent. Therefore, the bending force acts on the straight portion 30b and the stretching force acts on the straight portion 30a, so that the strength is higher than that of the structure in which only the bending force is applied, and the slide bar 30 is composed of two independent bars. Can be increased.

  Moreover, in this embodiment, the screw 45 which fixes the guide rail 40 to a housing is provided, and the screw 45 is located in the front part of the front-back direction between the linear part 30a and the linear part 30b. The front part is a position where the slide bar 30 can be pulled out to the maximum. According to this, the function which fixes the guide rail 40 to a housing and the function as a stopper of the slide bar 30 can be combined, and the grill unit 4 can be comprised at low cost.

  In the present embodiment, the pair of slide bars 30 and 30 includes fixed portions 30d and 30d formed at right angles to the inner side in the width direction with respect to the straight portion 30a and the straight portion 30b, respectively, at the front ends. According to this, when the pair of slide bars 30 are arranged on the left and right, the parallelism between the left slide bar 30 and the right slide bar 30 is increased, in other words, the interval between the left and right slide bars 30 is set to the front. From the rear to the rear. As a result, friction when the slide bar 30 slides in the guide rail 40 can be reduced, and noise due to friction can be prevented.

  Moreover, in this embodiment, the guide rail 40 is provided with the contact member 41 with which the rear end upper part 30s of the linear part 30a contacts when the door 20 is pulled out. According to this, when the door 20 is pulled out, the linear portion 30a of the slide bar 30 abuts against the abutting member 41, whereby the inclination of the slide bar 30 can be suppressed, and the grill unit 4 can be used conveniently. It can be improved.

Moreover, in this embodiment, the grill pan 60 withdrawn / inserted with the slide bar 30 is provided, and the housing includes the temperature sensor 70 that contacts the bottom surface 60s of the grill pan 60 when the door 20 is closed. According to this, since the temperature sensor 70 can be brought into direct contact with the grill pan 60, the temperature of the grill pan 60 can be detected with high accuracy. It becomes possible.
In addition, this invention is not limited to above-described embodiment, In the range which does not deviate from the meaning of this invention, it can change variously. In the above-described embodiment, the slide bar 30 including the U-shaped portion 30c as the connecting portion has been described as an example, but other shapes such as a U-shaped shape may be used. In the present embodiment, the slide bar 30 is configured by bending one wire. The structure which connects 2 or 3 or more wires may be sufficient.
