As a supplementary explanation of the perspective view of FIG. 4A, the holder 33 of the present embodiment has, for example, a symmetrical shape.

  As shown in FIG. 4A, the holder 33 has linear portions 51a and 51g. The linear portions 51a and 51g have a bent portion that extends linearly along the slide bar 39 (see FIG. 2) from the front end to the rear end and is bent outward in the left-right direction near the rear end. The holder 33 includes a linear part 51c. The linear portion 51c is connected to the vicinity of the rear end portions of the linear portions 51a and 51g while being bent upward in a convex U-shape.

  Moreover, the linear part 51f which connects linear part 51a, 51g is connected to the front end of linear part 51a, 51g. The linear portion 51f has a shape that is gradually bent forward from the connecting portion at the front end of the linear portions 51a and 51g and then further bent obliquely downward. Although the details of the linear portion 51f will be described later, the linear portion 51f is fitted into and engaged with a groove portion 81 (see FIG. 8A) formed in the door joint 80. Thereby, the holder 33 is interlocked with the opening / closing operation | movement of the door 32 (refer FIG. 2), and position shift is prevented.

  The linear parts 51b1 and 51e are members that are formed at positions higher than the linear part 51c and the linear part 51f and restrict the movement of the grill pan 41 in the front-rear direction. The linear portions 51b1 and 51e serve as holding members for the grill pan 41, details of which will be described later. A flange 41e of the grill pan 41 is interposed in the linear portions 51b1 and 51e.

  The bottom plate 41a of the grill pan (flat plate) 40a has a stepped step structure including a bottom surface 60s1 and a bottom surface 60s2 (details will be described later).

  Further, a flange 41e that is bent outward is formed on the upper end 41d of the side plate 41b (see also FIG. 5B described later). The linear portions 51e and 51b1 of the holder 33 are interposed in the flange 41e portion, and the grill pan (flat plate) 40a is supported. Further, by providing the flange 41e as described above, even when the holder 33 is not attached to the grill pan (flat plate) 40a (when the holder 33 is completely removed from the grill unit 4), the grill pan (flat plate) 40a can be easily handled. It is easy to carry.

  FIG. 4C is a perspective view showing a grill pan (wave plate) 40 b in the grill pan 41. The grill pan (wave plate) 40 b is detachable from the holder 33. In addition, the grill pan (wave plate) 40b has a space (capacity) in which, for example, five fish (for example, sword fish) can be placed side by side with the head and tail facing forward and backward.

  As shown in FIG. 4C, the grill pan (wave plate) 40b includes a bottom plate 41a having a substantially square shape, and a side plate 41b that rises upward from the outer peripheral edge of the bottom plate 41a, and is configured in a concave shape. Has been.

  The grill pan (wave plate) 40b is made of a material such as a steel plate and has a surface coated with a fluorine coating agent or the like.

  On the upper surface of the bottom plate 41a, a plurality of ridge portions 41c extending in the width direction (left-right direction) are formed at intervals in the front-rear direction. Further, the protruding portion 41c1 (41c) located at one end (rear end) in the arrangement direction of the protruding portions 41c is formed to be shorter in the left-right direction than the other protruding portions 41c.

  A flange 41e that is bent outward is formed on the upper end 41d of the side plate 41b (see also FIG. 5 (d) below). And the linear part 51e, 51b1 of the holder 33 is interposed in the part of this flange 41e, and the grill pan (wave plate) 40b is supported. Further, by providing the flange 41e in this manner, even when the holder 33 is not attached (when the holder 33 is completely removed from the grill unit 4 or the like), the grill pan (wave plate) 40b can be easily handled, and the grill pan (wave The dish) 40b can be easily carried.

  In the following description, the grill pan (flat plate) 40a and the grill pan (wave plate) 40b may be referred to as the grill pan 41 unless otherwise specified.

Next, FIG.4 (d) is a perspective view explaining a mode that the cover body was mounted | worn with the grill pan (flat plate) 40a shown to (b). Moreover, FIG.4 (e) is a perspective view explaining a mode that the cover body was mounted | worn with the grill pan (wave plate) 40b shown to (c).
As shown in FIGS. 4D and 4E, grill pan (flat plate) 40a and grill pan (wave plate) 40b are fitted with a common lid 42 and cooked by grill unit 4 (see FIG. 1). It can be performed. Details of the lid 42 will be described later.

5A is a plan view of FIG. 4B, FIG. 5B is a cross-sectional view taken along line X1-X1 of FIG. 4A, FIG. 5C is a plan view of FIG. 4C, and FIG. It is X2-X2 arrow sectional drawing of).
First, it demonstrates, referring the top view which shows the grill pan (flat plate) 40a of Fig.5 (a), X1-X1 arrow sectional drawing of (a) of (b).
As shown in FIGS. 5 (a) and 5 (b), the grill pan (flat plate) 40a has a flange 41e bent outward at the upper end 41d of the side plate 41b. In addition, although this flange 41e is formed over the perimeter of a grill pan (flat plate) 40a in Fig.5 (a), it is not specifically limited to this. In other words, the flange 41e only needs to be formed at least at the portion carried by the holder 33, that is, at the upper end 41d portion of the side plate 41b before and after the grill pan (flat plate) 40a. Linear portions 51e and 51b1 of the holder 33 are interposed in the flange 41e portion so that the grill pan (flat plate) 40a can be supported on the holder 33.

  The grill pan (flat plate) 40a has a substantially stepped step structure in which the bottom plate 41a includes a bottom surface 60s1 and a bottom surface 60s2 further lowered by one step. The bottom surface 60s1 (bottom plate 41a) near the rear end is in contact with the linear portion 51c of the holder 33. That is, the grill pan (flat plate) 40a is supported at three points of the linear portion 51e, the linear portion 51b1, and the linear portion 51c of the holder 33 (three-point support) in a side view in the left-right direction.

Further, for example, a counter press process 41a1 having a substantially circular shape is applied to the bottom surface 60s2 of the grill pan (flat plate) 40a, that is, the center portion of the stepped bottom plate 41a.
As shown in FIG. 5 (b), the bottom surface 60s2 to which the seat pressing process 41a1 is applied is processed so as to apply a slight bending tension to the inside of the grill pan (flat plate) 40a, for example. There is no particular limitation. By doing so, for example, when the bottom plate 41a of the grill pan (flat plate) 40a is heated, the expansion direction is changed to a predetermined direction (in this case, the inner side of the grill pan (flat plate) 40a) even if the bottom plate 41a is thermally expanded. It is induced and it can prevent that a residual stress arises. That is, the grill pan 40a is not reversed by residual stress even when the bottom plate 41a is heated, so that a reverse sound is not generated.

  Note that the height from the flange 41e of the bottom surface 60s2 of the grill pan (flat plate) 40a is H1 when the height from the flange 41e to the linear portion 51c is H1, and the height from the linear portion 51c to the bottom surface 60s2 is H2. And H2, the height (H1 + H2) is a substantially uniform plane.

FIG.5 (c) is a top view which shows the grill pan (wave plate) 40b, (d) is X2-X2 arrow sectional drawing of (c).
As shown in FIG.5 (c), as for the grill pan (wave plate) 40b, the groove part 41g is formed between the protruding item | line part 41c and the protruding item | line part 41c. Further, a concave water reservoir 41h is formed on the upper surface of the bottom plate 41a in front of the front-end-side protruding strip portion 41c2 (41c). The water reservoir 41h is heated in a state where water is accumulated, so that superheated steam can be generated and smoke can be removed in a healthy menu to be described later.

  Here, the surface (upper surface) of the groove 41g has, for example, an inclined surface that descends in the left-right direction from the center portion, with the center portion in the left-right direction being at the highest position. In addition, on the upper surface of the bottom plate 41a, a joining portion 41i extending in the front-rear direction is formed on both the left and right sides of the groove portion 41g. Thereby, the water | moisture content and oil which flowed out from the to-be-heated material flow into the junction part 41i through the inclined surface of the groove part 41g, and can reduce a contact with a to-be-heated object.

  Further, as shown in FIG. 5D, a flange 41e bent outward is formed at the upper end 41d of the side plate 41b of the grill pan (wave plate) 40b. In addition, although this flange 41e is formed over the perimeter of a grill pan (wave plate) 40b in FIG.5 (c), it is not specifically limited to this. That is, the flange 41e may be formed at least on the portion carried by the holder 33, that is, the upper end 41d portion of the side plate 41b before and after the grill pan (wave plate) 40b. Linear portions 51e and 51b1 of the holder 33 are interposed in the flange 41e so that the grill pan (wave plate) 40b can be supported on the holder 33.

  The grill pan (wave plate) 40 b is configured such that the bottom plate 41 a near the rear end is in contact with the linear portion 51 c of the holder 33. That is, the grill pan (wave plate) 40b is supported at the three points of the linear portion 51e, the linear portion 51b1, and the linear portion 51c of the holder 33 (three-point support) in a lateral side view.

The height H1 from the height of the flange 41e at the rear end portion of the grill pan (wave plate) 40b to the linear portion 51c of the holder 33 is determined from the height of the flange 41e at the front end portion of the grill pan (wave plate) 40b. It is slightly shorter than the height H3 up to the bottom plate 41a (H1 <H3). That is, the bottom plate 41a is provided to be inclined so as to be slightly lowered from the rear end toward the front end (details described later).
Furthermore, when compared with the height (H1 + H2) from the flange 41e of the bottom surface 60s2 of the grill pan (flat plate) 40a of FIG. 5B, the magnitude relationship of H1 <H3 <H1 + H2 is satisfied. More specifically, for example, when the height H1 is about 50 mm, it is manufactured so as to satisfy 50 mm <height H3 <60 mm (H2≈10 mm). However, the height H3 of the grill pan 40b is set so as not to contact the detection rod 86 (see FIG. 3) of the dish type discrimination sensor Ss1 even when the grill pan (wave plate) 40b is mounted on the grill unit 4 in the reverse direction. Shall.

  The length H1 from the height of the flange 41e at the rear end portion of the grill pan (wave plate) 40b to the linear portion 51c of the holder 33 is determined from the height of the flange 41e at the rear end portion of the grill pan (flat plate) 40a. The holder 33 is formed to have the same length H1 as the linear portion 51c. By doing in this way, it becomes possible to measure the grill pan 41 having different shapes with the same holder 33 and using the same temperature sensor 70 (detailed later).

  In other words, the grill pan (wave plate) 40b and the grill pan (flat plate) 40a have different depths from the flange 41e of the upper end 41d (upper surface) of the side plate 41b to the mounting surface on which the heated object of the bottom plate 41a is placed. . The holder 33 (holding member) holds the flange 41e of the grill pan (wave plate) 40b and the grill pan (flat plate) 40a.

6A is a bottom perspective view of FIG. 4B, and FIG. 6B is a bottom perspective view of FIG. 4C.
As shown in FIGS. 6A and 6B, when the holder 33 is mounted on the grill pan (flat plate) 40a and the grill pan (wave plate) 40b, the linear portion 51g and the linear portion 51a of the holder 33 are seen. Is formed so as to enter the inside of the bottom plate 41a of the grill pan (flat plate) 40a and the grill pan (wave plate) 40b. By adopting such a shape, even if the flange 41e (see FIGS. 5B and 5D) of the grill pan (flat plate) 40a and grill pan (wave plate) 40b falls off the holder 33, the holder 33 It is received by the linear part 51g and the linear part 51a. That is, it is possible to prevent the grill pan (flat plate) 40a and the grill pan (wave plate) 40b from completely falling from the holder 33 onto the floor or the like.

  Further, the control bars 51h and 51i of the holder 33 are arranged in the center of the side surfaces of the grill pan (flat plate) 40a and the grill pan (wave plate) 40b so that the hands are not touched when the grill pan (flat plate) 40a and the grill pan (wave plate) 40b are taken out. The portion is formed by bending downward over a predetermined length. By exhibiting such a shape, burns can be prevented. (Only the right side is shown in FIG. 6A)

(A) of FIG. 7 is a top view of a cover body, (b) is X3-X3 arrow sectional drawing of (a), (c) is X4-X4 arrow sectional drawing of (a).
The lid body 42 is formed by enameling a thin plate formed in a substantially square shape in plan view with, for example, an iron plate, but is not particularly limited thereto.
As shown in FIG. 7A, the lid 42 has a recess 42a that fits into the upper opening of the grill pan (flat plate) 40a.

  A flange portion 42b is formed on the outer periphery of the concave portion 42a. The flange portion 42b contacts the upper end 41d (flange 41e) of the grill pan (flat plate) 40a. A convex surface portion 42c having a substantially square shape in plan view is formed at the center of the concave portion 42a.

  Further, a step portion 42d is formed on the side surface (circumferential surface) 42c1 of the convex surface portion 42c (see FIG. 7A). Further, on the upper surface of the convex surface portion 42c, a plurality of holes 42e for removing steam are formed.

  The handle 43 is formed to be bent so as to exhibit, for example, a substantially U-shape in a side view of FIG. The handle 43 includes base portions 43a and 43a that are erected in a direction orthogonal to the front-rear direction (depth direction) of the lid body 42, and a grip portion 43b that extends in the front-rear direction (depth direction). .

As shown in FIGS. 7B and 7C, the grip 43b of the handle 43 is in a state of being floated (separated) from the bottom surface 42a1 of the recess 42a. Thus, since the clearance gap S is formed between the holding | grip part 43b and the bottom face 42a1, the clearance gap S becomes a knob allowance, the handle 43 can be grasped easily and the lid 42 can be removed easily.
Moreover, the upper surface of the convex part 42c is set to the same height as the upper surface of the flange part 42b (see FIGS. 7B to 7C).
As described above, by providing the lid 42 as the grill pan 41, the cooking width (for example, steamed dishes such as steamed rice bowls, and goyoza) can be expanded.

8A and 8B are views of the grill unit 4 with the door 32 opened, in which FIG. 8A is a perspective view illustrating how the holder engages with the door joint, and FIG. 8B is a view taken along the X5-X5 arrow in FIG. It is sectional drawing.
In addition, description of the door 32 is abbreviate | omitted in Fig.8 (a). Further, a grill pan (flat plate) 40a is illustrated as an example of the grill pan 41. However, the grill pan 41 may be a grill pan (wave plate) 40b.
As shown in FIG. 8A, the holder 33 has a linear portion 51f fitted into a slit-like groove portion 81 formed in the door joint 80 so that the holder 33 is engaged therewith (also FIG. 8B). See).

FIG. 8B is a longitudinal sectional view showing a state in which the door 32 of the grill unit 4 is opened, and is a sectional view taken along arrow X5-X5 in FIG. Note that the grill unit 4 of the present embodiment is provided with a regulating mechanism (not shown) that prevents the door 32 from being opened any more when the drawer amount when the door 32 is opened reaches a predetermined stroke amount.
As shown in FIG. 8B, when the door 32 is fully opened, the entire grill pan 41 can be pulled out to the front of the heating base 12. This makes it easy to lift the grill pan 41 directly above (see the white arrow in FIG. 8B), and it is not always necessary to tilt the grill pan 41 when it is taken out. As a result, it is possible to prevent moisture and oil from the heated object accumulated at the bottom of the grill pan 41 from adhering to the heated object again, and to prevent spillage from the grill pan 41.

Further, even when the door 32 is fully opened, the linear portions 51a and 51g are provided with bent portions 51a1 and 51g1 which are U-shaped in a side view so that a part of the holder 33 remains inside the cooking chamber 26. (See also FIG. 4 (a)). Accordingly, when the linear portions 51a and 51g slide in the side plate 26b immediately above the rail cases 49 and 49 (see also FIGS. 3 and 2) as the door 32 is opened and closed, the linear portions 51a and 51g It is possible to prevent the slide bar 39 from being pulled out beyond the step Δ and falling off. That is, a smooth opening / closing operation of the door 32 can be ensured.
Furthermore, tube-shaped silicone rubber 51j may be applied to the bent portions 51a1 and 51g1 in portions that slide in contact with the inside of the side plate 26b immediately above the rail cases 49 and 49. The silicone rubber 51j can be mounted by, for example, cutting a tube and fitting it into the bent portions 51a1 and 51g1. The silicone rubber 51j can prevent the generation of metallic sound when the bent portions 51a1 and 51g1 slide in contact with the inside of the side plate 26b immediately above the rail cases 49 and 49.

FIG. 9 is a cross-sectional view showing a temperature sensor that detects the temperature of the grill pan.
As shown in FIG. 9, the sensor cover 71 is formed so as to have a substantially rectangular shape in a cross-sectional view in the front-rear direction of the central portion (see also FIG. 3). Further, the upper surface portion of the sensor cover 71 has a shape in which the vicinity of the front end portion rises into a convex shape having a substantially mountain shape in cross section, and has a circular flat portion 71a at the top.

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.
Further, the base portion 72 b of the sensor portion 72 is disposed so as to protrude slightly upward from the flat portion formed at the rear of the upper surface of the sensor cover 71. By doing in this way, the contact area with the grill pan 41 is limited to the flat part 71a, and more accurate temperature measurement is possible.

  The sensor holding member 74 is interposed between the holding fitting 74a and the circular portion 72a of the sensor portion 72, and presses the circular portion 72a of the sensor portion 72 against the sensor cover 71 (planar portion 71a) (appropriate plate). Springs, compression coil springs 74b, and cushion materials such as glass wool). The holding metal piece 74a has a plate shape in cross section, and a recess 74c is formed at a position corresponding to the sensor part 72 so that a part of an urging member (for example, the compression coil spring 74b) is accommodated and can be held. .

  In the temperature sensor 70 configured as described above, the sensor cover 71 is fixed to the bottom plate 26d (see also FIG. 3) via screws 75 and 75. However, the fixing method of the sensor cover 71 is not particularly limited to this.

FIGS. 10A and 10B are diagrams for explaining the state before the holder gets over the temperature sensor, FIG. 10B shows the state after the holder gets over the temperature sensor, and FIG. 10C shows the state after the holder gets over the temperature sensor. is there.
In FIG. 10, a grill pan (flat plate) 40 a is illustrated as an example of the grill pan 41. However, the grill pan 41 may be a grill pan (wave plate) 40b.
As shown in FIG. 10 (a), before the door 32 is fully closed, the linear portion 51 c (the rearmost linear portion 51 c) of the holder 33 that supports the grill pan 41 is first placed on the inclined surface 71 b of the sensor cover 71. Contact (striking).
At this time, the linear portion 51b1 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. 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 41 and the inclined surface 71 b of the sensor cover 71 in the moving direction (front-rear direction) of the grill pan 41, the grill pan 41 does not hit the sensor cover 71.

  Then, when the door 32 is further pushed from the state shown in FIG. 10A, the linear portion 51c of the holder 33 rises while sliding on the slope 71b, and as shown in FIG. It rides on the flat part 71a. At this time, the grill pan 41 is supported by the linear portion 51 c and the bottom surface 60 s 1 of the grill pan 41 is located higher than the flat portion 71 a, so that the grill pan 41 does not contact the sensor cover 71.

  When the door 32 is further pushed from the state shown in FIG. 10B, the linear portion 51c of the holder 33 moves backward while sliding on the flat portion 71a, as shown in FIG. 10C. The linear portion 51c moves while sliding from the flat surface portion 71a to the rear inclined surface 71c. At this time, the bottom surface 60s1 of the grill pan 41 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 41 is stored, the holder 33 (the linear portion 51c) abuts against the sensor cover 71 before the grill pan 41, so that the surface of the grill pan 41 can be prevented from being worn by an impact.

  Further, since the temperature sensor 70 is brought into direct contact with the grill pan 41 as shown in the present embodiment, the temperature of the grill pan 41 can be accurately detected.

11A is a front view showing a state in which the grill pan (with a lid) is stored in the cooking chamber, and FIG. 11B is a cross-sectional view taken along line X6-X6 in FIG.
In FIG. 11, the door 32 is removed from the door joint 80. A lid 42 is attached to the grill pan 41.
In FIG. 11, the door 32 is not shown. Further, a grill pan (flat plate) 40a is illustrated as an example of the grill pan 41. However, the grill pan 41 may be a grill pan (wave plate) 40b.

As shown in FIG. 11A, when the grill pan 41 with the lid 42 is stored in the cooking chamber 26, the side plate 41b of the grill pan 41 is as high as possible in the vicinity of the upper heater 27a (in the cooking chamber 26). On the other hand, it has a shape extending up to the maximum height at which the grill pan 41 can be retracted and retracted.
For example, the distance H4 (shortest distance) between the upper heater 27a and the upper end of the handle 43 is set to about 3 mm.

FIG.11 (b) is sectional drawing which shows the state which accommodated the grill pan (state with a lid | cover) in a cooking chamber.

As shown in FIG. 11B, a recess 26a1 is formed in the upper plate 26a constituting the ceiling of the cooking chamber 26, and an upper heater 27a is accommodated in the recess 26a1. Thereby, for example, even if the height of the side plate 41b of the grill pan 41 is maximized, it is possible to prevent the upper end of the grill pan 41 or the lid body 42 from coming into contact with the upper heater 27a. Therefore, in this embodiment, the flange 41e (upper surface flange portion) of the grill pan (flat plate) 40a or the grill pan (wave plate) 40b held by the holder 33 (holding member) is positioned at a height near the upper surface of the cooking chamber 26. Has been.

  Although not shown, the grill unit 4 may be provided with a halogen heater in the upper vicinity of the entrance of the opening 26e (position P). In the case where a halogen heater is provided at the position of symbol P, the inside of the cooking chamber 26 can be easily seen by the lamp function of halogen.

  In addition, the grill pan 41 is inclined so that the bottom plate 41a is slightly lowered from the rear part to the front part when housed in the cooking cabinet 26. As a result, when the grill pan 41 is, for example, a grill pan (flat plate) 40a, moisture and oil components from the object to be heated accumulate in the front portion of the bottom plate 41a due to the action of gravity. Further, even when the grill pan 41 is, for example, a grill pan (wave plate) 40b, when moisture and oil components from the object to be heated flow out from the groove 41g (see FIG. 5C) toward the left and right side plates 41b and 41b. , And is collected at the front portion of the bottom plate 41a by the action of gravity.

  As shown in FIG. 11 (b), the gap H5 between the bottom surface 42a1 of the handle 43 and the grip portion 43b is about 20 mm, but there is no particular limitation as long as there is a gap that is easy to grip.

12A and 12B are diagrams for explaining a grill pan dish type discrimination sensor, wherein FIG. 12A is a top perspective view, FIG. 12B is a front view, and FIG. 12C is a cross-sectional view taken along the line X7-X7 in FIG.
As shown in FIG. 12A, a dish type discrimination sensor Ss1 for the grill pan 41 is attached to the rear end of the heating base 12. The dish type discriminating sensor Ss1 is a sensor for discriminating which of the grill pan (flat plate) 40a and the grill pan (wave plate) 40b is inserted. Here, the dish type determination sensor Ss1 includes a detection rod 86, a spring 87 (see also FIG. 3), and a sensor unit.

  As shown in FIGS. 12B and 12C, the detection rod 86 and the spring 87 of the dish type discrimination sensor Ss1 are arranged in the sensor cover 71 of the temperature sensor 70 and in the left-right direction with respect to the sensor unit 72. Installed at different positions. A spring 87 is inserted into the detection rod 86 so as to bias the detection rod 86 forward. The front end of the detection rod 86 comes into contact with the position of the lower end of the side plate 41b when the grill pan (flat plate) 40a is inserted, and is slightly pushed backward against the biasing force of the spring 86. (See the solid arrow in FIG. 12C). When the detection rod 86 is pressed slightly rearward, a sensor unit (see FIG. 12A, not shown in FIG. 12C) installed outside the cooking chamber 26 is energized.

13 (a) to 13 (c), 14 (a), and 14 (b) are diagrams for explaining a mechanism of detection of the door sensor. First, FIG. 13A is a diagram for explaining the cross-sectional direction, FIG. 13B is a cross-sectional view taken along the line X8-X8 in FIG. 13A, and FIG. 13C is a partially enlarged view of a portion J in FIG.
As shown in FIG. 13A, the grill unit 4 according to the embodiment includes, for example, a door sensor Ss2. The door sensor Ss2 may be a sensor having a mechanism for energizing when the door 32 is in a closed state, for example.

Here, in this embodiment, the correct insertion direction is defined regardless of the dish type of the grill pan 41.
More specifically, for example, when the grill pan (flat plate) 40a is used, the side plate 41b of the grill pan (flat plate) 40a is detected by the sensor cover 71 and the detection unless the bottom surface 60s1 is rearward (that is, the back side in the pulling direction). It will come into contact with the rod 86. In that case, it can no longer be inserted into the back side of the cooking chamber 26, and the temperature measurement of the grill pan (flat plate) 40a by the temperature sensor 70 becomes impossible.
Further, even when the grill pan (wave plate) 40b is used, if the water reservoir 41h (see FIG. 5C) is not inserted so as to be in front (that is, the front side in the pulling direction), the above-mentioned in FIG. As described above, since the height relationship from the flange 41e of the bottom plate 41a is H1 <H3, the flange 41e is lifted from the holder 33 and becomes unstable. Further, for example, the distance between the water reservoir 41h and the halogen heater provided at the position indicated by the symbol P in FIG. Furthermore, since it becomes the downstream position of the air introduced into the cooking chamber 26, the steam is exhausted from the exhaust duct 36k2 provided immediately above it before the steam is evenly distributed inside the cooking chamber 26. It will end up.

Therefore, in the present embodiment, when the grill pan 41 is not inserted in the correct direction, the door 32 is not completely closed and the door sensor Ss2 is not energized. This can give the user an opportunity to confirm the insertion direction.
FIG. 13B and FIG. 13C show an example of a cross-sectional view when, for example, a grill pan (wave plate) 40b is inserted in the reverse direction.
The grill unit 4 of the present embodiment is provided with a protrusion 85 on the upper portion of the rear plate 26c (see also FIG. 3). The protrusion 85 is disposed at a position where it comes into contact with the flange 41e when the grill pan (wave plate) 40b is inserted in the opposite direction. And it restrict | limits so that the door 32 cannot be drawn in in the drawer | drawer-out rear side any more.
In addition, the code | symbol H6 in FIG.13 (c) has shown the lifting amount from the linear part 51b1 of the holder 33 of the flange 41e when a grill pan (wave plate) 40b is inserted in the reverse direction (in this case, H6). ≒ satisfying H3-H1).

  Even when the front and rear direction of the grill pan (flat plate) 40a is inserted in the opposite direction, the sensor cover 71 shown in FIGS. 10A to 10C and the detection rod 86 shown in FIG. Due to the structural relationship, the side plate 41 b of the grill pan (flat plate) 40 a comes into contact with the sensor cover 71 and the detection rod 86. This restricts the further insertion of the grill pan (flat plate) 40a into the back side of the cooking chamber 26. In this way, the door 32 is not completely closed but is in a half-open state.

14A is a cross-sectional view taken along the line X9-X9 in FIG. 13A, and FIG. 14B is a partially enlarged view of a portion K in FIG.
As shown in FIGS. 14 (a) and 14 (b), the protrusion 32 shown in FIG. 13 (c) causes the door 32 to be in a half-open state by the width H7, and further drawing into the cooking chamber 26 is performed. Be regulated. In this case, the support column 90 of the door sensor Ss2 is biased around the rotation shaft 91 by the biasing force of the spring 92. Then, the protruding portion 93 that protrudes in the direction of pressing the door 32 from the front end of the column portion 90 is brought into contact with the contacted plate 96 provided on the door 32. In this state, the terminal portion 94 is not in contact with the terminal portion 95, and the door sensor Ss2 is not energized.
When the door 32 is completely closed, the projection 93 of the support column 90 is pressed against the non-contact plate 96 of the door 32 against the biasing force of the spring 92. Then, the terminal portion 94 is rotated clockwise around the rotation shaft 91 and comes into contact with the terminal portion 95, whereby the door sensor Ss2 is energized.

FIG. 15 is a diagram for explaining a mechanism for discriminating the dish type and insertion direction of the grill pan from the combination of detection signals of the dish type discrimination sensor Ss1 and the door sensor Ss2. In FIG. 15, ◯ indicates an energized state, and x indicates a non-energized state.
As shown in FIG. 15, when the grill pan (flat plate) 40a is inserted, the dish type discrimination sensor Ss1 is the detection rod 86 (see FIG. 12 (c)) both when inserted in the forward direction and in the reverse direction. Is pressed by the grill pan (flat plate) 40a, and is energized.
In addition, when the grill pan (wave plate) 40b is inserted, the dish type discrimination sensor Ss1 detects the detection rod 86 (see FIG. 12 (c)) when the grill pan (wave plate) 40b is inserted. Dish) Since it is located below the bottom plate 41a of 40b, it is not pressed and is in a non-energized state.

Further, when the grill pan (flat plate) 40a and the grill pan (wave plate) 40b are inserted in the forward direction, the door sensor Ss2 is connected to the cooking chamber 26 of the door 32 by the projection 85 (see FIG. 13C). Pull-in is not regulated. Therefore, the door 32 is completely closed and the door sensor Ss2 is energized.
When the grill pan (flat plate) 40a is inserted in the reverse direction, the sensor cover 71 or the detection rod 86 restricts the door 32 from being pulled into the cooking chamber 26. Further, when the grill pan (wave plate) 40b is inserted in the reverse direction, the protrusion 85 (see FIG. 13C) restricts the door 32 from being pulled into the cooking chamber 26. In any case, the door 32 is in a half-open state, and the door sensor Ss2 is in a non-energized state.

That is, as shown in FIG. 15, by detecting the energization pattern of the plate type discrimination sensor Ss1 and the door sensor Ss2, it is electronically identified what type of grill pan 41 is inserted in the forward direction or the reverse direction. be able to.
As described above, for example, when a dish type inappropriate for cooking is inserted, a warning can be displayed on a display unit (not shown). Furthermore, even if the correct dish type is inserted, if it is inserted in the reverse direction, a warning can be displayed on a display unit (not shown). In this way, the user can be given an opportunity to confirm the state of the grill pan 41.

(Action / Effect)
As described above, in the grill unit 4 of the present embodiment, the flange 41e is provided at least at the upper end 41d of the side plate 41b in the front and rear direction of the grill pan 41, and the linear portions 51e and 51b1 of the holder 33 are interposed below the flange 41e. It was set as the structure to be equipped.
Accordingly, the same holder 33 can be used regardless of whether the grill pan 41 is a grill pan (flat plate) 40a or a grill pan (wave plate) 40b.
Moreover, the same holder 33 can be used regardless of the plate type, and the distance from the upper end 41d of the side plate 41b of the grill pan 41 to the upper plate 26a or the upper heater 27a in the cooking chamber 26 can be made the same. .
In addition, when the grill pan 41 with the lid 42 is stored in the cooking chamber 26, the side plate 41b of the grill pan 41 is as high as possible in the vicinity of the upper plate 26a or the upper heater 27a of the cooking chamber 26 (in the cooking chamber 26). On the other hand, it has a shape extending up to the maximum height at which the grill pan 41 can be retracted and retracted.
That is, the distance from the upper end of the side plate 41b to the upper plate 26a of the cooking chamber 26 is made as small as possible. This prevents the side plate 26b (side surface) and the bottom plate 26d (bottom surface) in the cooking chamber 26 from becoming dirty even if moisture or oil that has flown out when the fish or fat-rich meat is heated in the grill pan 41. can do. Therefore, cleaning in the cooking chamber 26 is facilitated.
In particular, when cooking is performed using the grill pan (flat plate) 40a, the vertical height (length) of the side plate 41b is increased (lengthened) so that the bottom plate 41a comes near the lower heater 27b. A larger object to be heated can be cooked. Further, by arranging the bottom plate 41a so as to be close to the lower heater 27b, the heat generated by the lower heater 27b can be efficiently and uniformly transmitted into the grill pan (flat plate) 40a. In this way, the heat transfer performance of the grill pan (flat plate) 40a can be further improved by utilizing the high heating power of the lower heater 27b.
Further, by using the holder 33 described above, the lid body 42 used for the grill pan (flat plate) 40a and the grill pan (wave plate) 40b can be provided in the vicinity of the upper heater 27a as well. As a result, the heat generated by the upper heater 27a can be efficiently and uniformly transmitted to the grill pan 41 (the grill pan (flat plate) 40a and the grill pan (wave plate) 40b).

  Further, in the present embodiment, the temperature of the grill pan 41 is measured quickly and accurately because the bottom plate 41a of the grill pan 41 directly climbs over the circular flat portion 71a directly above the sensor portion 72 of the sensor cover 71 and the temperature is detected. Can do.

  In the present embodiment, the bent portions 51a1 and 51g1 on the linear portions 51a and 51g, which are the rear portions of the holder 33 to which the grill pan 41 is mounted, are formed in the side plate 26b immediately above the rail cases 49 and 49 as the door 32 is opened and closed ( (See also FIG. 3). At this time, the tubular silicone rubber 51j is applied to the portions of the bent portions 51a1 and 51g1 that are in contact with the inside of the side plate 26b immediately above the rail cases 49 and 49. Thereby, even if the bent portions 51a1 and 51g1 slide in the side plate 26b immediately above the rail cases 49 and 49, generation of metal sound can be prevented.

  In the present embodiment, a part of the holder 33 to which the grill pan 41 is attached remains in the cooking chamber 26 even when the door 32 is fully opened. Specifically, the bent portions 51a1 and 51g1 on the linear portions 51a and 51g corresponding to the rear portions of the holder 33 remain in the side plate 26b immediately above the rail cases 49 and 49. Thus, when the bent portions 51a1 and 51g1 slide in the side plate 26b immediately above the rail cases 49 and 49, the bent portions 51a1 and 51g1 are pulled out beyond the step Δ (see FIG. 8B), and the slide bar 39, It is possible to prevent it from dropping on 39. That is, a smooth opening / closing operation of the door 32 can be ensured.

In addition, the grill unit 4 of the present embodiment includes a dish type discrimination sensor Ss1 having a detection rod 86 (see FIG. 12C). The detection rod 86 of the dish type discrimination sensor Ss1 is installed so that, for example, when the grill pan (flat plate) 40a is inserted into the cooking chamber 26, the front end of the detection rod 86 comes into contact with and is pressed to the back in the pulling direction. The Moreover, when inserting the grill pan (wave plate) 40b into the cooking chamber 26, the detection rod 86 is installed so as not to come into contact.
In addition, the grill unit 4 of the present embodiment includes a protrusion 85 (see FIG. 13C) that causes the door 32 to be in a half-open state when the grill pan 41 is inserted into the cooking chamber 26 in the reverse direction, the sensor cover 71, and the detection rod. 86 and a door sensor Ss2.
As described above, by detecting the energization patterns of the dish type discrimination sensor Ss1 and the door sensor Ss2, it is possible to electronically identify which dish type of the grill pan 41 is inserted in the forward direction or the reverse direction.

  The above-described embodiment has been described in detail for easy understanding of the present invention, and is not necessarily limited to the one having all the configurations described.

In addition, a part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and a part or all of the configuration of another embodiment can be added to the configuration of one embodiment. It is. Further, it is possible to add, delete, and replace other configurations for a part of the configuration of the embodiment.
That is, various modifications may be made without departing from the spirit of the present invention.

Specifically, for example, in the above-described embodiment, the case where the flange 41e is suspended from the holder 33 of the grill pan 41 by the front and rear side plates 41b (see FIGS. 5B and 5D) has been described as an example. Alternatively, a method may be used in which a flange is provided at the upper ends of the left and right side plates 41b to be suspended.
In addition, the grill pan 41 has been described as being supported at three points in the side view in the left-right direction with the holder 33, but is not particularly limited thereto.

  Further, the holder 33 on which the grill pan 41 is placed has a front end engaged with the groove 81 of the door joint 80. Further, the rear end portion of the holder 33 has been described as an example in which the bent portions 51a1 and 51g1 on the linear portions 51a and 51g slide in the side plate 26b immediately above the rail cases 49 and 49 (see also FIG. 3). However, the holder 33 may be suspended from the upper plate 26a of the cooking chamber 26 so as to be slidable in the pulling direction.

  Further, the door sensor Ss2 has been described as a separate body from the protrusion 85 (see FIG. 13C), but may be integrated. In that case, what is necessary is just to provide the same kind of structure as dish type discrimination | determination sensor Ss1.

  In addition, the grill pan 41 has been described with respect to the grill pan (flat plate) 40a and the grill pan (wave plate) 40b, but other grill pans 41 may be used. The grill pan 41 does not have to be rectangular in plan view.
