Description

  The present invention relates to a grill, and more particularly to a technique for detecting the temperature of a grill and detecting the opening / closing of a grill door.

  Conventionally, a saucer temperature sensor is disposed on the bottom surface of the cabinet, and the temperature is measured by bringing the temperature sensing portion into contact with the bottom surface of the saucer (see, for example, Patent Document 1) or the temperature of the saucer temperature sensor provided on the exhaust path. A device that detects opening / closing of a grill door by a change (see, for example, Patent Documents 2 and 3) has been proposed.

JP-A-06-105750 Japanese Patent Laid-Open No. 2004-113697 JP 2004-121378 A

  However, the conventional technique has the following problems.

  (1) As shown in Patent Document 1, when a saucer temperature sensor is arranged on the bottom surface of the grill cabinet, the temperature sensing part of the saucer sensor always rubs against the bottom surface of the saucer due to sliding associated with opening and closing of the door. If the door is opened and closed to avoid this problem, the temperature sensing part and the bottom of the saucer will be separated only while the saucer is moving. There was a problem that the opening / closing detection mechanism and the tray moving mechanism became complicated.

  (2) Therefore, as shown in Patent Documents 2 and 3, when a method of detecting the opening / closing of the door by the temperature change of the tray temperature sensor (or exhaust temperature sensor) is adopted, the combustion of the grill is used for the opening / closing detection. Therefore, if combustion starts without closing the door, the counter burns due to exhaust leaking from the door gap until the combustion is stopped (or the heating power is reduced) by detecting opening and closing, There was a risk of exhaust gas hitting the user.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to detect the temperature of the pan and start combustion on the grill while having a simple structure and hardly causing mechanical failure. An object of the present invention is to provide a safe grill that can detect opening and closing of a grill door.

In order to solve the above problems, the grill of the present invention, pan 37 to a support 25 that works in response to the opening and closing of the grille door 31 is supported, the pan 37 is the grill cabinet 30 with the opening and closing of the grille door 31 The grill is configured to move back and forth, and a tray temperature sensor 18 for detecting the tray temperature by contacting the rear end 37a of the tray 37 is provided at the rear of the grill cabinet 30 so as to be movable back and forth. The tray temperature sensor 18 has a grill door opening / closing detection function for detecting the opening / closing of the grill door 31, and the temperature sensing portion 19 of the tray temperature sensor 18 is urged forward to keep the grill door 31 closed. As a means for biasing the grill door 31 in the closing direction, the force that biases the grill door 31 in the closing direction using the magnetic attraction force is maintained. Saucer temperature The closed state maintaining mechanism 43 set to be larger than the force that the temperature sensing portion 19 of the sensor 18 is urged forward, or when the grill door 31 is closer to the closed position than a predetermined distance, spring force is used. The grill door 31 automatically operates to reach the closed state, and the force that biases the grill door 31 in the closing direction is larger than the force that biases the temperature sensing portion 19 of the tray temperature sensor 18 forward. It is characterized in that at least one of the set assist mechanisms 50 is provided .

With such a configuration, by providing the tray temperature sensor 18 with a grill door opening / closing detection function, the opening / closing detection of the grill door 31 can be made simple and less susceptible to mechanical failure. In addition, the opening and closing of the grill door 31 can be detected by one tray temperature sensor 18 even when the grill is not burning, and at the same time, the grill can detect the tray temperature accurately. Even when the grill door 31 is closed, even if the tray temperature sensor 18 is in contact with the rear end 37a side of the tray 37 and the grill door 31 is biased in the opening direction, the closed state maintaining mechanism 43 or The grill door 31 can be reliably closed by at least one of the assist mechanisms 50.

Further, in place of the saucer 37, a dedicated pan 70 for cooking in the oven oven can be supported by the support 25, and the temperature sensing portion 19 of the saucer temperature sensor 18 is provided on the rear end 70a side of the dedicated pan 70. It is preferable that the abutment temperature sensor 18 detects the temperature of the dedicated pan 70 and detects the opening / closing of the grill door 31. In this case, even when a dedicated pan 70 for cooking in the oven oven is used by exchanging with the pan 37, the open / close state of the grill door 31 can be detected by the pan temperature sensor 18, and the temperature of the dedicated pan 70 can be directly measured. Therefore, it becomes possible to perform more accurate control.

In order to solve the above problems, the grill of the present invention is such that the tray 37 is supported by the support body 25 that is interlocked according to the opening and closing of the grill door 31, and the tray 37 is grilled along with the opening and closing of the grill door 31. A grill having a structure that moves back and forth in the storage 31, and a tray temperature sensor 18 that abuts the rear end side of the tray 37 and detects the tray temperature is provided at the rear of the grill chamber 30 so as to be movable back and forth. The saucer temperature sensor 18 has a grill door opening / closing detection function for detecting the opening / closing of the grill door 31, and a dedicated pan 70 for cooking a dutch oven can be supported on the support body 25 instead of the saucer 37, The tray temperature sensor 18 is configured to have a determination function for determining whether the tray 25 or the dedicated pan 70 is supported by the support 25.
With such a configuration, by providing the tray temperature sensor 18 with a grill door opening / closing detection function, the opening / closing detection of the grill door 31 can be made simple and less susceptible to mechanical failure. In addition, the opening and closing of the grill door 31 can be detected by one tray temperature sensor 18 even when the grill is not burning, and at the same time, the grill can detect the tray temperature accurately. Further, since the tray 37 and the dedicated pan 70 can be discriminated, it is possible to control the thermal power according to whether the tray 37 or the dedicated pan 70 is inserted into the grill cabinet 30.

Further, by providing a difference in the shapes of the saucer 37 and the dedicated pan 70, the distance to which the temperature sensing part 19 of the saucer temperature sensor 18 is pushed is different, and the discrimination function is the sensitivity of the saucer temperature sensor 18. It is preferable to determine whether the one supported by the support body 25 is the tray 37 or the dedicated pan 70 according to the distance to which the warming portion 19 is pushed. In this case, it is possible to easily determine whether the tray 37 or the dedicated pan 70 is supported by the support body 25 in the grill warehouse 30 with a simple configuration in which the shapes of the tray 37 and the dedicated pan 70 are different.

In addition, the determination function includes a first detection unit 81 that detects the tray 37 and a second detection unit 82 that detects the dedicated pan 70, and the grill door 31 is closed and the tray 37 is stored. It is preferable that the second detector 82 does not detect the tray 37 until the grill door 31 is opened and the tray 37 is pulled out. In this case, in the case of Dutch oven cooking using the dedicated pan 70, the grill timer time is increased because the contents are less likely to ignite compared to the case where the cooking object is grilled by placing the grill on the tray 37. it can. On the other hand, in the case of grilling cooking, since the tray 37 is not in a state where it is detected by the second detection means 82, there is a possibility that a long grill timer is set as in the case of Dutch oven cooking using the dedicated pan 70, Since the control for cooking the pan 70 is not executed, it is safe.

Further, as a means for biasing the grill door 31 in the closing direction in order to maintain the grill door 31 in the closed state, the closed state maintaining mechanism 43 using a magnetic attraction force or the grill door 31 has a predetermined distance. It is preferable to include at least one of the assist mechanisms 50 that operate so that the grill door 31 automatically reaches the closed state using the spring force when approaching the closed state. In this case, even when the grill door 31 is closed, the closed state maintaining mechanism 43 is provided even when the tray temperature sensor 18 is in contact with the rear end 37a of the tray 37 and the grill door 31 is biased in the opening direction. Alternatively, the grill door 31 can be reliably closed by at least one of the assist mechanisms 50.

In addition, the whole or part of the tray 37 or the dedicated pan 70 is made of a metal having high thermal conductivity, and the inner surface of the tray 37 or the dedicated pan 70 has high non-adhesiveness. It is preferable that the surface treatment is performed. In this case, the temperature of the temperature detected by the tray temperature sensor 18 with respect to the temperature of the tray 37 is good by making the tray 37 (or the dedicated pan 70) using a metal having high thermal conductivity such as copper or aluminum. As a result, more accurate control can be executed, and cooking performance and safety are improved. Further, the surface of the tray 37 (or the dedicated pan 70) is subjected to a surface treatment with high non-adhesiveness such as fluorine to improve the care.

Further, the metal having a high thermal conductivity is used only for a part of the tray 37 or the dedicated pan 70 that extends from the rear end portion that contacts the temperature sensitive portion 19 of the tray temperature sensor 18 to the central portion. It is preferable to configure as described above. In this case, the use of a metal material having a high thermal conductivity can improve the temperature detection accuracy of the tray 37 and the like, and extends from the rear end 37a portion of the tray 37 that contacts the temperature sensitive portion 19 to the center portion. Since parts other than the part, or parts other than the part extending from the rear end 70a contacting the temperature-sensitive part 19 in the dedicated pan 70 to the center part, can each be made of a material having low thermal conductivity, This makes it possible to improve the heat retention.

Further, it is preferable that a sensor antifouling gutter 95 for guiding the oil dripping from the food to be cooked into the saucer 37 is disposed above the temperature sensing part 19 of the saucer temperature sensor 18. . In this case, fish oil or the like dripped from the food to be cooked can be guided into the saucer 37 by the sensor antifouling gutter 95, so that it is possible to prevent the dirt from the cooked food from adhering to the temperature sensing unit 19.

Further, when the temperature detected by the tray temperature sensor 18 becomes equal to or higher than a predetermined monitoring temperature, or when the temperature gradient of the temperature detected by the tray temperature sensor 18 becomes steeper than a predetermined monitoring gradient, combustion occurs. It is preferable to configure so as to stop. In this case, since combustion can be stopped according to the temperature or temperature change of the portion near the oil to be cooked or the oil and fat generated from the food to be cooked, it is possible to reliably prevent ignition of the tray 37 and the like.

According to the first aspect of the present invention, by providing the tray temperature sensor with a grill door opening / closing detection function, mechanical failure is unlikely to occur, and the door opening / closing detection mechanism is simple, but the tray temperature is accurately measured. It can be detected well, and the opening and closing of the grill door can be detected before starting combustion on the grill, and even when used with the door open, the counter is burnt by the exhaust generated by the combustion for detecting the opening and closing of the door. In addition, it is possible to obtain a grill that does not cause the user to hit the exhaust gas. Further, even when the tray temperature sensor abuts on the rear end side of the tray and is urged in the opening direction of the grill door, the grill door can be reliably closed.

  Next, the case where the grill 3 is used will be described. The upper part of the front surface of the movable member provided with the operation panel 6 is pushed so that the operation panel 6 protrudes forward from the front surface of the main body and is exposed upward as shown in FIG. By pressing the menu switch 64, the a la carte menu switch 65, or the timer increase / decrease switch 62 shown with a finger, the cooking menu, the a la carte menu, the cooking time, etc. are input for grill cooking, and then the ignition / fire extinguishing switch 61 is pressed with the finger. The grill 3 is ignited by pushing and performing an ignition input operation. Thus, automatic cooking is performed by controlling the heating power, cooking time, and the like by the control unit 10 (see FIG. 3) so that the intended grill cooking is performed. When the input of the cooking setting is finished, the upper part of the front surface of the movable member is pushed and stored so that the operation panel 6 is not exposed to the outside, whereby the operation panel 6 can be prevented from becoming dirty during cooking by the grill 3. When it is desired to stop the automatic cooking during the automatic cooking in the grill 3, the automatic cooking can be stopped by extinguishing the fire by pressing the ignition / extinguishing switch 61 with a finger.

  The menus that can be switched by the menu switch 64 include “sake ware”, “fillet”, and “dried fish”, and the à la carte menu switch 65 can be selected from three types of “dutch oven”, “pizza”, and “baked rice ball”. ing. In addition, when “pizza” is selected from the à la carte menu, an accessory metal cooking plate (not shown) is placed on the grill 33, and bread, pizza, etc. are placed on the cooking plate. It is recommended in the instruction manual that the cooking object 34 is placed and cooked, and the user uses the accessory cooking plate according to this and operates the à la carte menu switch 65 as necessary. Cook.

  In the grill 3, a temperature rise rate (referred to as a temperature rise gradient) that changes in accordance with a difference in the mounting state of the cooking object 34 on the grill 33 in the initial stage after the heating by the grill burner 32 is started. A cooking temperature detecting means 80 (see FIG. 3) is provided. The cooking temperature detecting means 80 detects the combustion exhaust gas temperature. The control unit is configured to calculate the temperature increase gradient based on the detection information of the cooking temperature detection unit 80, and based on the information on the temperature increase gradient determined in the determination information calculation process, The total heating time TT from the execution of the determination information calculation process to the end of the heating of the object to be cooked 34 is obtained. The total heating time TT applies a predetermined value or obtains a value from a predetermined calculation formula according to the type of cooking menu and the placement state of the cooking object 34.

  When the temperature rise gradient is small, that is, when the temperature rise value at a predetermined time is small, it can be determined that a large cooked object 34 having a large heat capacity is placed on the grill 33 of the grill 3. Depending on the gradient, the total heating time TT is calculated and set in a long time, and when the temperature rise gradient is large, that is, when the temperature rise value at a predetermined time is large, the grill 33 of the grill 3 has a small heat capacity and a small cooking capacity. Since it can be determined that the object 34 is placed, the total heating time TT is calculated and set in a short time according to the temperature rise gradient. The total heating time TT is calculated by substituting a value corresponding to the temperature increase gradient in advance or by substituting the value of the temperature increase gradient into a predetermined calculation formula.

  The elapsed time T1 from the time when heating by the grill burner 32 is started to the time when the total heating time TT is calculated and set is measured.

  Then, the remaining heating time T2 from when the total heating time TT is calculated and set until the heating of the object to be cooked 34 is determined as T2 = TT−T1, and T2 is displayed as a timer display unit for grill (timer in FIG. 6). It is displayed on the upper side of the increase / decrease switch 62).

  After displaying T2 on the grill timer display unit, the remaining heating time T2 displayed on the grill timer display unit is counted down over time, and when the display on the grill timer display unit becomes zero, the grill burner 32 is displayed. Is extinguished, and automatic grill cooking control is terminated.

  Hereinafter, the temperature detection and the grill door opening / closing detection function of the tray temperature sensor 18 of the present embodiment will be described.

  The grill door 31 is connected to a moving rail 25 (see FIG. 2) constituting a support. The moving rail 25 is supported so as to be movable back and forth along a fixed rail 25a (see FIG. 7). When the user pulls out or pushes in the grill door 31 with the handle, the tray 37 placed on the moving rail 25 and the grill 33 placed thereon move forward and backward. It is configured.

  As shown in FIG. 4, the temperature sensing unit 19 of the tray temperature sensor 18 is attached to the lower part of the rear plate 30 a of the grill cabinet 30 at the rear (back side) of the grill cabinet 30. The temperature sensing unit 19 is attached in a state of being biased toward the inside of the grill cabinet 30 by the spring force of the spring 46 (see FIG. 7). The temperature sensing unit 19 is configured to detect the tray temperature by contacting the rear end 37a of the back side of the tray 37 when the grill door 31 is closed.

  On the rear plate 30a above the temperature sensing unit 19 in the grill cabinet 30, a bowl-shaped sensor antifouling bowl 95 is projected. The sensor antifouling gutter 95 is for blocking the oil from the dropped fish and guiding it into the tray 37 so that the temperature sensitive unit 19 is not contaminated with the cooked food.

  The saucer temperature sensor 18 has a grill door opening / closing detection function. As shown in FIG. 4, one end of a connecting rod 17 is connected to the rear surface of the temperature sensing part 19 of the saucer temperature sensor 18, and the other end of the connecting rod 17 penetrates the rear plate 30a and protrudes outward. A magnetic body 40 is attached to the protruding portion of the connecting rod 17. The magnetic body 40 can be moved back and forth integrally with the temperature sensing unit 19. When the temperature sensing unit 19 does not come into contact with the rear end 37a of the tray 37, the magnetic body 40 is positioned in the front and is disposed close to the reed switch 42 (state shown in FIG. 4A). When the temperature sensing unit 19 abuts on the rear end 37a of the tray 37 and is pressed rearward, the magnetic body 40 also moves rearward and is disposed away from the reed switch 42 (FIG. 4B). State). In this manner, the magnetic body 40 moves in and out of the permanent magnet 41 and the reed switch 42 in conjunction with the movement of the temperature sensing unit 19 of the tray temperature sensor 18, thereby shielding the magnetic lines of force M toward the reed switch 42. (Refer to FIG. 5A). Permeation of the magnetic force lines M toward the reed switch 42 without allowing the magnetic force lines M toward the reed switch 42 to be allowed to pass (see FIG. 5B), and the grill door 31. Is configured to detect the opening and closing of the. 5A and 5B, the left side of the permanent magnet 41 is described as the N pole and the right side as the S pole. However, the left side may be the S pole and the right side may be the N pole.

In addition to the above-described configuration, at least one of the following two closed state maintaining mechanisms 43 and assist mechanisms 50 is provided as means for applying a bias to maintain the closed state of the grill door 31. It is configured. (See FIGS. 7 and 8.)
As shown in FIG. 7, the closed state maintaining mechanism 43 is provided on a contact surface between the grill door 31 and the inlet peripheral portion of the grill cabinet 30 and includes a permanent magnet 44 and a magnetic body 45 such as iron. The permanent magnets 44 are provided at two locations on the left and right sides of the grill door 31. When the grill door 31 is in the closed state, the permanent magnets 44 are magnetically attached to the magnetic bodies 45 provided at the two left and right locations on the front surface of the grill cabinet 30, and the closed state is maintained. It has become so.

  Further, an assist mechanism 50 is provided in the grill cabinet 30. For example, the assist mechanism 50 is configured by an automatic pulling device that automatically pulls the moving body pulled out from the fixed body into the fixed body from a predetermined position with a spring force. When the grill door 31 is closer to the closed position than a predetermined distance, the assist force of the assist mechanism 50 is activated and the grill door 31 is automatically closed. In this case, the position at which the grill door 31 is detected to be closed is adjusted so as to be shorter than a predetermined distance at which the assist mechanism 50 operates, so that an erroneous operation of the opening / closing detection does not occur.

  In addition, the force that biases the grill door 31 in the closing direction by the closed state maintaining mechanism 43 and the assist mechanism 50 is set to be larger than the spring force of the spring 46 that pushes the temperature sensing portion 19 of the tray temperature sensor 18 forward. Thereby, when the grill door 31 is closed, the temperature sensing portion 19 is reliably brought into contact with the rear end 37a of the tray 37, and at the same time, the closed state of the grill door 31 is maintained.

  When the temperature detected by the tray temperature sensor 18 is equal to or higher than a predetermined monitoring temperature, for example, 300 ° C., which is close to the oil ignition temperature, or the temperature gradient of the detected temperature is equal to a predetermined monitoring gradient, for example, 20 deg / min. When it becomes steep as described above, the control unit 10 (see FIG. 3) stops the combustion by stopping the supply of gas.

  According to the said structure, the following effects are obtained.

  (1) In the state where the grill door 31 is opened (the state shown in FIG. 8A), the temperature sensing unit 19 is moved forward by the spring 46. At this time, the magnetic body 40 causes the magnetic force lines M from the permanent magnet 41 to move. Since shielding is performed, the reed switch 42 is kept OFF. In this state, the urging force of the assist mechanism 50 and the closed state maintaining mechanism 43 and the urging force of the spring 46 against the grill door 31 do not work.

  When the grill door 31 is closed (the state of FIGS. 8B to 8C), the urging force by the assist mechanism 50 gradually increases, and when the grill door 31 is completely closed (FIG. 8D). State), the urging force by the assist mechanism 50 is reduced, and instead, the urging force (magnetic attraction force) by the permanent magnet 44 of the closed state maintaining mechanism 43 is increased, and the grill door 31 is maintained in the closed state. At this time, the temperature sensing part 19 of the saucer temperature sensor 18 is pushed by the rear end 37 a of the saucer 37 and moves backward against the spring force of the spring 46, so that the magnetic body 40 has a line of magnetic force M from the permanent magnet 41. Is no longer shielded, the reed switch 42 is turned on, and it is detected that the grill door 31 has been changed from the open state to the closed state.

  As a result, the tray temperature sensor 18 has a function of detecting opening / closing of the grill door, and there is no need to separately provide parts such as a conventional micro switch dedicated to detecting opening / closing of the grill door. Moreover, since the magnetic body 40, the permanent magnet 41, and the reed switch 42 constituting the grill door opening / closing detection function are provided outside the grill cabinet 30, the opening / closing detection of the grill door 31 is simple and mechanical failure occurs. A difficult structure can be obtained. In addition, it is possible to detect the opening and closing of the grill door 31 even when the grill is not burning, and at the same time, the temperature sensing unit 19 can directly contact the rear end 37a of the tray 37, so that the tray temperature can be accurately detected. 3 can be used.

  (2) The temperature sensing part 19 of the saucer temperature sensor 18 abuts on the rear end 37a of the saucer 37, so that the temperature of the saucer 37 can be directly measured, and the temperature of the oil (dropped from the fish) accumulated in the saucer 37 is measured. It is possible to know more accurately than indirect measurement from the exhaust gas temperature as in the prior art. And, if the saucer temperature exceeds 300 ° C., the combustion is stopped, or if the temperature rise gradient of the saucer temperature suddenly increases, the combustion is stopped more safely. It becomes possible to prevent the ignition of. For example, the ignition temperature of the oil ≈ 320 ° C., the ignition temperature of the oil ≈ 360 ° C., and the oil accumulated in the tray 37 starts decomposing, so that the heat of decomposition is generated, so that the tray temperature rises rapidly. By detecting this, combustion can be stopped in accordance with the temperature of the food to be cooked 34 or the oil and fat generated from the food to be cooked 34 and the temperature change, so that the catch 37 can be reliably prevented from igniting and safety is further improved. It will be improved.

  (3) Since the grill door 31 is biased and maintained in the closing direction by both or one of the closed state maintaining mechanism 43 and the assist mechanism 50, the grill door 31 overcomes the force of the spring 46 that biases the temperature sensing unit 19 forward. The grill door 31 is surely maintained in the closed state, and there is no fear of the grill door 31 being inadvertently opened during cooking.

  (4) Since the sensor antifouling gutter 95 is provided above the temperature sensing part 19 of the saucer temperature sensor 18 for guiding oil or the like dripping from the object to be cooked into the saucer 37. Fish oil or the like dripped from the object is guided into the saucer 37 through the sensor antifouling cage 95, and it is possible to prevent dirt from the cooked product from adhering to the temperature sensing unit 19.

  FIG. 9 shows another embodiment. On the rail 25 for movement of the grill door 31, a dedicated pan 70 for cooking in a Dutch oven can be placed instead of the tray 37 on which the grill 33 is placed (state of FIG. 9B). The depth dimension S2 of the dedicated pan 70 (FIG. 9B) is set to be longer than the depth dimension S1 of the tray 37 (FIG. 9A), so that the grill door 31 is closed. The magnetic body 40 is configured so that the position in the front-rear direction is different.

  The tray temperature sensor 18 can detect the temperature of the dedicated pan 70 placed and used in place of the tray 37 (the state shown in FIG. 9D), and uses either the tray 37 or the dedicated pan 70. Even in the state, it is possible to detect opening and closing of the grill door 31. In this example, the first permanent magnet 41 and the first lead for detecting the first detection state in which the grill door 31 is closed when the tray 37 on which the grill 33 is placed is placed on the rail 25. First detection means 81 is provided in combination with the switch 42. Further, second detection means 82 is provided behind the first detection means 81. The second detection means 82 includes a second permanent magnet 41a and a second permanent magnet 41a for detecting a second detection state in which the grill door 31 is closed when the dedicated oven pan 70 for dutch oven cooking is placed on the rail 25. It consists of a combination with the reed switch 42a. The determination states of the tray 37 and the dedicated pan 70 are shown in [Table 1] below.

 First, when the grill door 31 is opened when the tray 37 is used (the state shown in FIG. 9A), the temperature sensing unit 19 moves forward, the first reed switch 42 is turned off, and the second reed switch 42a is kept on. At this time, the control unit 10 (see FIG. 3) determines that the grill door 31 is in an open state and makes combustion impossible. After that, when the grill door 31 is closed (the state shown in FIG. 9C), since the distance at which the tray 37 pushes the temperature sensing unit 19 is short (shallow), the magnetic body 40 has the first reed switch 42 and the second reed switch 42a. The reed switches 42 and 42a are both turned on, and the control unit 10 determines that the grill door 31 is in the closed state and enables combustion.

  On the other hand, when the grill door 31 is opened when the dedicated pan 70 is used (the state shown in FIG. 9B), the temperature sensing unit 19 moves forward, the first reed switch 42 is turned off, and the second reed switch 42a is turned on. Therefore, the control unit 10 determines that the grill door 31 is in the open state, and makes combustion impossible. After that, when the grill door 31 is closed (the state shown in FIG. 9D), the distance to which the dedicated pan 70 pushes the temperature sensing unit 19 is long (deep). Therefore, the magnetic body 40 has the first reed switch 42 and the second reed switch. 42a, the first reed switch 42 is finally turned on, the second reed switch 42a is turned off, and the controller 10 determines that the grill door 31 is in the closed state and burns. Make it possible.

  By doing so, the tray 37 on which the grille 33 is placed is placed on the rail 25, and the grill pan storage state is placed on the rail 25. In either case of the dutch oven pan storage state, it is possible to detect the opening / closing of the grill door, and it is possible to determine whether the tray 37 or the dedicated pan 70, and the maximum timer that can be set by the grill timer is determined according to the determination result. The value can be changed or the temperature adjustment control method can be automatically performed by the control unit.

  Further, in the conventional Dutch oven cooking, only rough heating power adjustment is performed by the exhaust gas temperature. However, in this embodiment, the pan temperature sensor 18 is used even when the dedicated pan 70 for cooking the Dutch oven is used by replacing the pan 37. Thus, the opening and closing of the grill door 31 can be detected, and the temperature of the dedicated pan 70 can be directly measured, so that more accurate control can be performed.

  In addition, it is only necessary to provide a difference in the depth dimension (shape) of the tray 37 and the dedicated pan 70 so that the distance to which the temperature sensing unit 19 is pushed in is different, so that it is easy to distinguish between the tray 37 and the dedicated pan 70. It is possible to control the thermal power according to whether the tray 37 or the dedicated pan 70 is used according to the determination result.

  That is, in the case of Dutch oven cooking using the dedicated pan 70, the grill timer time can be increased because the contents are less likely to ignite compared to the case where the cooking object is grilled by placing the grill on the tray 37. . On the other hand, when the tray 37 is used, the second reed switch of the second detecting means 82 is in a state from when the grill door 31 is opened and the tray 37 is pulled out to when the grill door 31 is closed and the tray 37 is stored. 42 a is always kept in the ON state (the states of FIGS. 9A and 9C), and there is no possibility that the tray 37 is detected by the second detection means 82. As a result, in the case of grilling cooking, there is no possibility that a long grill timer is set as in the case of Dutch oven cooking using the dedicated pan 70 or the control for cooking the dedicated pan 70 is not executed. It is extremely safe. On the other hand, in the case of Dutch oven cooking using the dedicated pan 70, the content of the contents is more than that in the case of grilled net cooking in which the cooking object such as fish is directly placed on the grilled net 33 in the grilled net storage state. Since ignition is difficult to occur, the maximum value of the timer that can be set in the case of cooking using the dedicated pan 70 can be automatically set longer by the control unit 10 than in the case of grilling cooking, and as a result, it is easy to use. Can be improved.

  In the example of FIG. 9, the embodiment using the two reed switches 42 and 42a is shown. However, the present invention is not limited to this, and a configuration in which position detecting means such as a micro switch is separately used may be used.

  The material of the saucer 37 or the dedicated pan 70 of the embodiment is configured using a metal having a high thermal conductivity such as copper or aluminum in order to accurately measure the temperature. Thereby, since the temperature is almost uniform throughout the pan 37 (dedicated pan 70), the temperature can be accurately detected by the pan temperature sensor 18, and more accurate heating control can be executed. Improvement is achieved.

  In addition, you may comprise only the saucer 37 or a part of exclusive pan 70 using a metal with high heat conductivity. By doing so, the cost can be reduced. Moreover, in this case, it uses only for a part of part which extends to the center part from the rear-end 37a contact | abutted with the temperature sensing part 19 of the saucer 37 (similar pan 70 is also the same), and heat-conducting the other part It is desirable that the material is made of a low material. Thereby, the followability of the temperature detected by the tray temperature sensor 18 can be improved with respect to the temperature of the tray 37 (dedicated pan 70), and the temperature detection accuracy can be improved. It is possible to improve the performance. Moreover, the part with high thermal conductivity extended to the center part from the part contact | abutted with the temperature sensing part 19 of the saucer 37 (exclusive pan 70) is comprised by the separate part from the main body of the saucer 37 (exclusive pan 70), It is good also as a structure attached to a main body as another component.

  Furthermore, it is desirable that the inner surface of the tray 37 or the dedicated pan 70 is subjected to a surface treatment with high non-adhesiveness such as fluorine. In this case, care is improved by surface treatment with high non-adhesive properties such as fluorine.

  The grill of the present invention is not limited to the case where gas is used as an energy source for heating, and electricity or other energy may be used as an energy source for heating.
