Description

  The present invention relates to a cooking device in which opening and closing of a cooking chamber inside a cooking device body is performed by sliding a door member relative to the cooking device body.

  Conventionally, a gas stove with a grill having a grill in a stove body has been widely used as a model of a heating cooker. This gas stove with a grill has a grill door integrally including a door portion that forms a part of a front operation portion of the gas stove and a placement portion (a grill pan) on which a food can be placed, and the grill door is slid. The door is opened and closed by operation. That is, the gas stove with a grill opens and closes the door by pulling or pushing the grill door by sliding movement, and puts food into and out of the grill.

  Here, heat resistant glass is used for the door from the viewpoint of visualizing the inside of the grill and ensuring high heat resistance, but in order to ensure the design of the front operation part of the gas stove, a decorative plate is attached to the heat resistant glass. There is a demand to flatten the front operation part. However, when the decorative plate is attached in this way, the number of parts related to the door portion increases, and furthermore, the heat resistance glass is incorporated in the grill door, so that the door portion and thus the grill door becomes heavy. Therefore, the door member becomes difficult to operate when putting food into and out of the grill, and the usability of the grill becomes very poor.

Therefore, as a technique for solving the problem that the grill door becomes heavy, a gas stove with a grill, in which the door portion is divided from the handle, is disclosed in Patent Document 1, for example. In the stove of Patent Document 1, when the handle is pulled out toward the front, the door portion is rotated in a single-opening manner, and the door portion is held in a horizontal state on the top plate and the counter top of the stove. Accordingly, if this gas stove with a grill is used, the weight of the grill door is reduced, so that the handle can be easily put in and out, and the operability of the grill door is ensured.
Utility Model Registration Gazette No. 2563515 (page 3-4, Fig. 1)

  However, when the gas stove with a grill of Patent Document 1 is used, in a state in which the handle is pulled out, that is, in a state where the door portion is opened horizontally, the door portion protrudes greatly from the end of the top plate (countertop) to the near side. As a result, there is a problem that the door part interferes with the operation, and the operation parts such as ignition and thermal power adjustment become difficult to operate. Therefore, there is a case where the operation unit has to be operated in a cramped posture, and the gas stove having a structure in which the door itself is lifted has a problem that it is not easy to use.

  In particular, since a thick glass plate with a certain thickness is used for the door part to ensure heat resistance, if the door part is thick, an area that is difficult to operate will be generated. The problem of operability deterioration of the operation unit becomes significant. In addition, when a lever type operation unit is used for adjusting the thermal power, if the lever operating direction is the horizontal direction of the stove body, the hand can easily hit the door near the operating end of the operating lever. When the operation part for operation is a lever type, the operability of the operation part is particularly concerned.

  Also, from the current situation that the door becomes thicker to ensure heat resistance, when the door is opened, the front operation space is taken up by the door's thickness, and the entrance area of the grill There was also a problem that was limited. In addition, when the door is open horizontally, a holding mechanism is required to hold the door open, but the door is made of thick heat-resistant glass, which increases the weight of the door and makes the holding mechanism large (complex ), Which may increase the cost.

  The object of the present invention is to provide cooking that can ensure the operability of the operation portion such as ignition and thermal power adjustment while ensuring the operability of the sliding door member without impairing the design of the front surface of the door portion. Is to provide a vessel.

In order to solve the above-mentioned problems, in the invention according to claim 1, a cooking chamber is provided inside the cooker body, and a dish receiver that supports a grill plate with respect to the cooker body, and a tip of the dish receiver. In a heating cooker that opens and closes the cooking chamber by sliding and moving a door member composed of an integrally connected grille door , the door rotates when the door member is opened. A lid member that starts and closes the front surface of the upper part of the grill door to an open state that covers the upper part of the cooking chamber entrance and exit , and the front surface of the grill door and the lid when the door member is closed The gist is that a gap is formed between the back surface of the member .

According to this invention, when the door member is slid to the front side and the cooking chamber doorway is opened, the lid member is in an open state covering the upper side of the cooking chamber doorway. Therefore, when the door member is opened, the hot exhaust gas coming out of the cooking chamber is blocked by the lid member, and it becomes difficult for the exhaust gas to flow to the user side who operates the door member, and the usability when opening the door member is ensured. The Moreover, in this structure, since a cover member also becomes the design surface of a cooking-by-heating machine, a door member can be lightened by that much by making a cover member into a separate part from a door member like this invention. Therefore, the door member can be slid with a light force, and operability when the door member is slid is ensured. In addition, if a gap is formed between the front surface of the grill door and the back surface of the lid member, even if the grill door becomes hot as the temperature increases in the cooking chamber during cooking, it is difficult for the heat to be transmitted to the lid member through the gap. Become. Therefore, even if the grill door becomes hot during cooking, the lid member is prevented from becoming excessively hot.

  Furthermore, when employing a configuration that blocks high-temperature exhaust, for example, a configuration in which the door portion of the door member and the handle are divided and the door itself is rotated is also conceivable. However, the door part is relatively thick to ensure heat resistance, and the door part itself is large. Therefore, when the door part is rotated, when the door part is opened, the cooker body The door part interferes with the front of the cooking unit, and it becomes difficult to operate the operation part located on the front of the cooker body. However, if a configuration using a lid member is used, a lid member that is thinner than the door portion and smaller in area can be used, so even if a configuration that blocks high-temperature exhaust is adopted, the operation portion can be operated. It becomes difficult to cause trouble.

  According to a second aspect of the present invention, in the first aspect of the present invention, the biasing means capable of biasing the lid member to the open state side, and the biasing force of the biasing means to the open state side of the lid member. The gist of the present invention is that it is provided with a conversion means for converting to the rotational force.

  According to this invention, in addition to the operation of the invention described in claim 1, the urging force of the urging means is converted by the converting means into the turning force on the open side of the lid member, and the lid member is opened by this turning force. Rotate to the side. Therefore, when the door member is opened, the lid member can be automatically rotated to the open state side.

  According to a third aspect of the present invention, in the second aspect of the present invention, when the door member is closed, the conversion means is pushed by the door member to reverse the opening operation. The gist is to turn the lid member to close the lid member.

  According to this invention, in addition to the operation of the invention described in claim 2, when the door member is closed, the conversion means is pushed by the door member along with the sliding movement of the door member at that time, and thereby the lid member is opened. The lid member is closed by rotating in the opposite direction to that during the operation. Therefore, the lid member can be closed in conjunction with the closing operation of the door member, and the operation of closing the lid member is simplified.

In the invention according to claim 4 , in the invention according to any one of claims 1 to 3 , the lid member starts opening on the back surface of the lid member in accordance with the opening operation of the door member. The gist of the present invention is that a rectifying section is formed for escaping the hot exhaust gas flowing out from the cooking chamber doorway to the side of the lid member.

According to this invention, in addition to the action of the invention according to any one of claims 1 to 3 , since the rectifying portion is formed on the back surface of the lid member, the door member is opened to open the cooking chamber entrance / exit. When this happens, the hot exhaust gas coming out of the cooking chamber is released to the side of the user by the rectifying unit. Accordingly, the exhaust gas is more difficult to flow to the user side who operates the door member, and the usability when the door member is opened is improved.

According to a fifth aspect of the present invention, in the invention according to any one of the second to fourth aspects, the detection means for detecting the open / closed state of the door member based on the rotational position of the conversion means, and the detection means And an ignition control means for performing ignition control based on a detection signal from the engine.

According to this invention, in addition to the action of the invention according to any one of claims 2 to 4 , it is determined whether or not the door member is in a completely closed state by using the detection signal of the detection means. Is possible. Therefore, for example, if the door member is not in a completely closed state, control that does not allow ignition is performed, so that ignition in a state in which the door member is not completely closed can be prevented, improving the safety and reliability of the cooking device. It can satisfy the improvement in performance.

According to the present invention, since the lid member is formed on the cooker main body, the operation unit for ignition, thermal power adjustment, etc., while ensuring the operability of the sliding door member without impairing the design of the front surface of the grill door. The operability can be ensured.

Hereinafter, an embodiment of a heating cooker embodying the present invention will be described with reference to FIGS.
FIG. 1 is a front view showing an attached state of a gas stove 1 with a grill. The gas stove with a grill 1 is a countertop type that can be attached to the countertop 2 in an embedded state, and is attached to the countertop 2 by being inserted into the countertop 2 from the upper surface opening 3. A front opening 4 is formed on the front surface of the counter top 2, and when the gas stove with grill 1 is attached to the counter top 2, the front surface of the gas stove with grill 1 faces forward from the front opening 4.

  2 and 3 are perspective views of the gas stove 1 with a grill. The gas stove with a grill 1 has a substantially box-shaped main body case 5 whose upper surface is open, and a top plate 6 is attached to the upper surface of the main body case 5. The gas stove with a grill 1 accommodates a plurality (three in this example) of gas burners 7 inside a main body case 5, and these gas burners 7 are exposed to the outside through the burner openings 7 a of the top plate 6. . Gotoku 8 is attached to each burner opening 7a. In addition, the gas stove 1 with a grill corresponds to the heating cooker, and the main body case 5 corresponds to the cooker main body.

  The gas stove with a grill 1 includes a grill 9 at the center of the main body case 5. The grill 9 is used when cooking grilled food, and a tray holder (also referred to as a swing arm) 12 on which a grill pan 11 is placed is slidably accommodated in the main body case 5 in a grill chamber 10 (see FIG. 3) in the grill 9. Yes. The dish tray 12 is formed, for example, by making a metal wire into a substantially U shape, and is in a state where the grill dish 11 is placed by supporting the outer periphery of the grill dish 11.

  A grill door 13 is attached and fixed to a pair of tips of the tray receiver 12. The grill door 13 is integrally connected to the tray receiver 12 by inserting the tips of the tray receiver 12 into a pair of locking holes (not shown) formed on the back surface of the grill door 13. Therefore, when the door is opened and closed by pulling or pushing the grill door 13, the tray receiver 12 is guided and slid by the rail (not shown), and the grill chamber 10 is opened or closed. The grill room 10 corresponds to a cooking room.

  A handle 13a is formed in the lower part of the grill door 13, and when the grill door 13 is opened by pulling the handle 13a when the grill door 13 is in a closed state, the tray receiver 12 and the grill door 13 are guided by the rail to the front side. It slides and it will be in the state (state shown in FIG. 3) by which the grill pan 11 was pulled out. When the grill door 13 is in the open state, as shown in FIG. 3, the tray receiver 12 is rotated downward about the base end 12 a by the weight of the grill door 13 and the grill door 13 is lowered downward. Therefore, the opening area of the grille opening 15 can be increased, and cooking operations can be easily performed.

  On the other hand, if the grill door 13 is closed by pushing the handle 13a when the grill door 13 is open, the tray receiver 12 and the grill door 13 are guided by the rail and slid to the depth side, and the grill chamber 10 is closed ( The state shown in FIG. When the grill door 13 is closed, the tray receiver 12 returns to a normal state, that is, a state where it is horizontal with respect to the grill pan 11. The tray receiver 12 and the grill door 13 constitute a door member, and the grill door 13 corresponds to a door portion.

  The grill door 13 is positioned on the front surface portion 5a of the main body case 5, and is flattened so as to be positioned on substantially the same plane as the front surface portion 5a. Thus, by flattening the front surface portion 5a of the main body case 5, the design of the front surface portion 5a is ensured. The grill door 13 includes a heat-resistant glass 13b, and the inside of the grill chamber 10 can be visually observed from the heat-resistant glass 13b. On both sides of the operation unit 5b of the main body case 5, a plurality (four in this example) of operation units 14 each including an ignition button of the gas burner 7, the grill 9, a thermal power adjustment switch, and the like are disposed.

  A flap 16 that is rotatable about the width direction of the main body case 5 as a rotation axis is attached to the upper end edge of the grill opening 15. The flap 16 makes it difficult for hot exhaust gas (fluid) coming out of the grill chamber 10 to flow to the user side (upward) when the grill door 13 is opened after grill cooking (including midway). When the grill door 13 is opened and the grill pan 11 is pulled out, the flap 16 is rotated to the front side to be in an open state (the state shown in FIG. 3), and when the grill door 13 is closed and the grill chamber 10 is closed. The flap 16 is turned to the depth side to be in a closed state (state shown in FIG. 2). The grill opening 15 corresponds to a cooking chamber entrance and exit, and the flap 16 corresponds to a lid member.

  4 is an enlarged view of a cross section taken along line AA in FIG. 5, and FIG. 5 is an enlarged view of a cross section taken along line BB in FIG. The flap 16 forms a design surface on the front surface of the main body case 5 when the flap 16 is closed by matching the external shape with the front surface portions 5a on both sides. On both sides of the flap 16, an opening / closing mechanism 17 that opens and closes the flap 16 as the grill door 13 opens and closes is disposed. The opening / closing mechanism 17 will be described below. A support frame 18 extending along the upper edge and side edge of the grill opening 15 is attached to the inner surface of the main body case 5. A pair of first rotation shafts 19 projecting inward so as to face each other are formed on the side walls on both sides of the support frame 18.

  Each first rotation shaft 19 supports a cam 20 that can rotate in the directions of arrows C1 and C2 in FIG. 5 with the rotation shaft 19 as a support shaft. The cam 20 is formed with a contact portion 20a (see FIG. 5) extending on the moving path of the grill door 13, and when the grill door 13 is closed, the upper portion of the grill door 13 contacts the contact portion 20a of the cam 20. In contact therewith, the cam 20 rotates to the opposite side (in the direction of arrow C1 in FIG. 5) with respect to the grill door 13. Further, a guide groove 20b is formed in the upper part of each cam 20. A pair of protrusions 16a projecting inward so as to face each other are engaged with each side wall of the flap 16, and the protrusions 16a are engaged with the guide groove 20b. The cam 20 corresponds to the conversion means.

  In the main body case 5, a pair of second rotating shafts 21 that protrude inward so as to face each other are formed on the inner wall facing the side wall of the flap 16. A flap 16 is supported on each second rotation shaft 21 so as to be rotatable in the directions of arrows D1 and D2 in FIG. In the main body case 5, a connecting plate 22 extending along the width direction of the main body case 5 is attached and fixed to the upper position of the support frame 18 by a plurality of screws (not shown).

  A spring spring 23 that biases the cam 20 toward the front side (flap 16 side) is interposed between each cam 20 and the connecting plate 22. One end of the spring spring 23 is locked to a locking piece 22 a formed by bending on the connecting plate 22, and the other end is locked to a locking pin 20 c that is formed to protrude from the cam 20. Therefore, the urging force of the spring spring 23 is converted into the rotational force of the flap 16 by the cam 20, and the flap 16 can be rotated in the directions of arrows D1 and D2 in FIG. 5 according to the positional relationship between the grill door 13 and the cam 20. It becomes. The spring spring 23 corresponds to the biasing means.

  Therefore, when the grill door 13 in the closed state shown in FIGS. 2 and 5 is opened, if the grill door 13 moves away from the contact portion 20a as shown in FIG. 6, the cam 20 is moved forward by the urging force of the spring spring 23. The rotation starts in the direction of the arrow C2 and the flap 16 starts rotating in the direction of the arrow D1. When the door opening operation is further continued, the cam 20 continues to rotate, and when the grill door 13 is separated from the cam 20, the flap 16 is placed on the upper surface of the main body case 5 (ie, as shown in FIGS. 7 and 8). The horizontal state with respect to the countertop 2 and the top plate 6), that is, the flap 16 is opened.

  On the other hand, when the opened grill door 13 shown in FIGS. 3 and 8 is closed, the grill door 13 contacts the contact portion 20a of the cam 20 as shown in FIG. When the grill door 13 is pushed further into the back, the cam 20 starts to rotate in the depth side (arrow C1 direction) against the urging force of the spring spring 23 as shown in FIG. It rotates in the direction D2. When the door closing operation is continued, the grill door 13 is completely closed. At this time, as shown in FIGS. 2 and 5, the flap 16 covers the front surface of the grill door 13 (on the same plane as the front surface portion 5a). In other words, the flap 16 is closed.

  FIG. 9 is a rear view of the flap 16. On the back surface of the flap 16, a rectifying unit 24 is formed to release high-temperature exhaust gas from the inside of the grill chamber 10 to the side of the user when the grill chamber 10 is opened by opening the door when the grill 9 is used. . The rectifying unit 24 has two first rectifying units 24a extending so as to be spaced apart from each other with the central portion at the top, and 2 inclined to fall toward the front side while being positioned at both ends of the flap 16. And two second rectifiers 24b.

  As shown in FIG. 5, a gap 25 is formed between the front surface of the grill door 13 (heat-resistant glass 13 b) and the back surface of the flap 16. The gap 25 is set to a width that allows the front surface of the main body case 5 to be in a flat state when the flap 16 is in a closed state. That is, when the gap 25 is formed in this way, the heat of the grill chamber 10 is not easily transmitted to the flap 16, and the flap 16 is closed even if the rectifying portion 24 is formed on the back surface of the flap 16. In addition, a flat state of the front surface of the main body case 5 can be secured.

  FIG. 10 is a block diagram illustrating an electrical configuration of the stove 1 with a grill. The stove with grill 1 includes a control device 26 that performs various controls such as ignition control and thermal power adjustment control of the stove 1, an ignition device 27 that ignites the gas burner 7 and the grill 9, and a main gas open / close valve and thermal power control, for example. And a valve 28 comprising a valve. The control device 26 controls the ignition device 27 based on the ignition operation of the operation unit 14 to perform ignition control, or controls the valve 28 based on the heating power adjustment operation of the operation unit 14 to perform thermal power adjustment control. The switch 29 corresponds to detection means, and the control device 26 corresponds to ignition control means.

  In addition, a switch 29 that switches on and off based on the positional relationship with the cam 20 is disposed on the rotation path of the cam 20. The switch 29 is turned on when the contact of the cam 20 is pushed when the grill door 13 is completely closed, and is turned off when the grill door 13 is opened. . The switch 29 is electrically connected to the control device 26, and the control device 26 performs ignition control of the ignition device 27 based on an ON signal or an OFF signal input from the switch 29.

Next, the operation of the gas stove with a grill 1 will be described.
First, when opening the grill door 13 in the closed state, an operation of pulling the grill door 13 forward is performed. At this time, as the grill door 13 slides and moves to the open state side, the upper portion of the grill door 13 and the cam 20 are operated. The relative position changes. At this time, the cam 20 starts to rotate in the direction of the arrow C2 in FIGS. 5 and 6 by the biasing force of the spring spring 23, and the flap 16 starts to rotate in the direction of the arrow D1 shown in FIGS. Start to open. As the opening operation of the grill door 13 continues, the flap 16 continues to rotate, and when the grill door 13 is completely separated from the cam 20, the flap 16 is open as shown in FIGS. It becomes.

  When the flap 16 is in the open state, the upper portion of the grille opening 15 is covered as if covered by the flap 16. Therefore, even if the grill door 13 is opened during cooking on the grill 9 or after cooking is finished, and hot exhaust gas flows out from the inside of the grill chamber 10, the exhaust air is blocked by the flap 16, and the grill door 13 is opened. Exhaust gas is difficult to flow to the user side. Therefore, the user can open the grill door 13 without being bothered by the high-temperature exhaust gas flowing out from the grill chamber 10, and the usability of the grill 9 is improved. Furthermore, since it is difficult for hot exhaust gas to flow upward, the countertop 2 and the top plate 6 are also prevented from being burnt.

  Further, since the flap 16 constitutes the design surface of the front surface portion 5a of the main body case 5, when the configuration of this example is adopted, the parts constituting the design surface of the front surface portion 5a of the main body case 5 are grilled. It becomes a separate part from the door 13, and the grill door 13 becomes light by that much. Therefore, it is possible to open and close the grill door 13 with a light force as compared with the case where the parts constituting the design surface are integrated with the grill door 13, and the opening and closing operation of the grill door 13 is facilitated. 13 operability is ensured.

  Further, the flap 16 only has to have a design surface of the front surface portion 5a of the main body case 5 and a lid that covers the top of the grill opening 15 when the grill door 13 is opened. Thin and small in area. Therefore, even if the flap 16 extends forward when the flap 16 is in the open state, it is less likely to interfere with the operation of the operation portions 14 on both sides of the flap 16 as compared with the configuration in which the grill door 13 itself is lifted. Therefore, if the configuration using the flap 16 is adopted, the high-temperature exhaust gas flowing out from the grill chamber 10 when the grill door 13 is opened can be blocked, and the operability of the operation unit 14 is ensured.

  Further, since the flap 16 is thin and small, even if the flap 16 is in an open state, the flap 16 does not take a large space for the front surface portion 5a of the main body case 5. Therefore, the grille opening 15 is hardly restricted by the flap 16, and a sufficient opening area of the grille opening 15 is ensured. In addition, when the grill door 13 is pulled out, the grill door 13 is lowered downward via the tray receiver 12, so that the opening area of the grill opening 15 can be further increased and cooking operation is further facilitated. Further, when the flap 16 is in the open state, a holding mechanism (in this example, the spring spring 23) for holding the open state is required. However, if the light flap 16 is used as in this example, the holding mechanism is simple. Just do things.

  On the other hand, when the opened grill door 13 is closed, the grill door 13 is pushed into the depth side. At this time, when the upper portion of the grill door 13 comes into contact with the contact portion 20a of the cam 20 during the door closing operation, the cam 20 resists the urging force of the spring spring 23 in the direction of the arrow C1 in FIGS. While starting to rotate, the flap 16 starts to rotate in the direction of arrow D2 in FIGS. 5 and 6 and starts to close. Then, as the closing operation of the grill door 13 continues, the flap 16 continues to rotate, and when the grill door 13 is completely closed, the flap 16 is closed as shown in FIGS. Thus, since the closing operation of the flap 16 is interlocked with the closing operation of the grill door 13, the closing operation of the flap 16 can be easily performed.

  Further, the control device 26 determines permission to ignite the grill 9 based on an on signal or an off signal from a switch 29 that is turned on / off by the cam 20. Therefore, in a state where the grill door 13 is not completely closed, that is, in a state where an off signal is output from the switch 29, the control device 26 permits ignition of the grill 9 even if the operation unit 14 is ignited. Without ignition, the grill 9 is not ignited. Therefore, it is not necessary to ignite the grill 9 when the grill door 13 is not completely closed, and the reliability of the apparatus is improved.

  Here, when the grill door 13 is opened and the food is put in, the grill door 13 is closed and cooking on the grill 9 is started, if the grill door 13 is not completely closed, the ignition of the grill 9 is not permitted. Even if the portion 14 is operated, the grill 9 is not ignited. When the grill door 13 is opened during cooking on the grill 9, the timer 26a starts counting from the time when the switch 29 is turned off, and the grill door 13 is closed until the timer 26a counts up. When 29 is turned on, the combustion state of the grill 9 is continued. On the other hand, when the timer 26a has counted up, the grill 9 is extinguished.

According to the configuration of the present embodiment, the following effects can be obtained.
(1) A flap 16 that can be rotated according to the opening / closing operation of the grill door 13 is provided in the main body case 5, and when the grill door 13 is closed, the flap 16 is closed to form a design surface of the front surface portion 5 a of the main body case 5. When the grill door 13 is in the open state, the flap 16 is opened to cover the top of the grill opening 15. Accordingly, since the flap 16 is a separate component from the grill door 13, the grill door 13 becomes lighter by that amount, and the opening and closing operation of the grill door 13 becomes easier. Further, since the flap 16 is thinner and smaller in area than the grill door 13, when the operation unit 14 is operated with the flap 16 in the open state, the flap 16 is less likely to get in the way. The operability of the unit 14 can also be ensured. Furthermore, since the thin and small flap 16 is rotated to cover the upper side of the grill opening 15, the grill opening 15 can be sufficiently secured, and the holding mechanism for holding the flap 16 in an open state is also simple. Just do things.

  (2) Since the spring spring 23 is interposed between the main body case 5 and the cam 20, and the urging force of the spring spring 23 enables the flap 16 to be rotated to the open state side via the cam 20, the grill door 13 With the opening operation, the flap 16 can be automatically rotated to the open state side.

  (3) When the grill door 13 is closed, the upper portion of the grill door 13 comes into contact with the contact portion 20a of the cam 20, so that the flap 16 is turned to the closed state to be closed. Therefore, the closing operation of the grill door 13 can be interlocked with the closing operation of the flap 16, and the work of closing the flap 16 can be easily performed.

  (4) Since the gap 25 is formed between the front surface of the grill door 13 (heat-resistant glass 13b) and the rear surface of the flap 16, even when the grill 9 is cooking, the temperature of the grill chamber 10 becomes high. The heat is not easily transmitted to the flap 16. Accordingly, when the grill door 13 is opened after the cooking is finished and the flap 16 is in the open state, even if the flap 16 is touched, it is difficult to cause trouble.

  (5) Since the flow straightening portion 24 is formed on the back surface of the flap 16, when the grill door 10 is opened by opening the grill door 13 during cooking by the grill 9 or after cooking, the hot exhaust gas coming out of the grill chamber 10 is straightened. The part 24 escapes to the side of the user. Therefore, the exhaust gas hardly leaks to the user side who opened the grill door 13, and the usability when the grill door 13 is opened is improved.

  (6) Based on the signal from the switch 29, the control device 26 permits the ignition device 27 to ignite on the condition that the grill door 13 is in a closed state. Therefore, it is not necessary to ignite the grill 9 when the grill door 13 is not completely closed, and the reliability of the apparatus can be improved.

In addition, the said embodiment is not limited to the said structure, You may change into the following aspects.
When the gap 25 is formed between the grill door 13 and the flap 16, for example, as shown in FIG. 11, the recess 25 may be formed in the grill door 13 to provide the gap 25.
