Japanese Unexamined Patent Publication No. 2003-343853

According to the above structure, the grill plate can be easily moved to the feeding position by one-touch operation, which is convenient because it is not necessary to manually pull out the grill plate.

However, for example, after the grill cooking is completed, or when the grill plate is fed out to check the cooking condition during the grill cooking, the grill plate heated in the grill storage moves to the feeding position. There was a risk of contact with the user.

The present invention has been made in view of such a situation, and an object of the present invention is to prevent the user from coming into contact with a hot grill plate or the like without impairing usability.

In order to achieve the above object, the present invention is configured as follows.

(1) The cooking cooker with a grill according to the present invention is provided with a grill storage having an opening on the front surface, and the heated object placing portion on which the heated object is placed is taken in and out through the opening. It ’s a cooker with a grill.
A drive unit that moves the heated object mounting portion in the front-rear direction between a storage position that is stored in the grill and a delivery position that is fed forward from the storage position through the opening. An operation unit that is operated to move the heated object mounting unit forward to the delivery position and retracted to the storage position, and a temperature detection unit that detects the temperature of the grill storage. A control unit that controls the drive unit based on the operation of the operation unit and the detection temperature detected by the temperature detection unit is provided.
Based on the detection temperature, the control unit reduces the speed of movement of the object to be heated by the drive unit when the detection temperature is high, as compared with when the detection temperature is low. To do.

According to the present invention, for example, after the grill cooking is completed, the cooked object to be heated is taken out, or the heated object placing portion is moved forward to the delivery position in order to check the cooking condition during the grill cooking. Or, when the heated object placing part is moved backward to the storage position after checking the cooking condition, the temperature detected by the temperature detection unit of the grill storage is high, so that the heated object placing part is also at a high temperature. If there is, the heated mounting portion is moved forward or backward at a low speed. When the detection temperature of the grill storage is high, such as after the grill cooking is completed or during the grill cooking, the heated object placing portion heated in the grill storage moves at a low speed, so that the user can use his / her hand. There is a margin to keep the body and the body away from the movement path of the object to be heated, and it is possible to suppress the contact with the high-temperature object to be placed.

Further, for example, when the object to be heated is moved forward to the delivery position to load the food before the grill is cooked, and then the object to be heated is moved backward to the storage position, the grill storage is used. Since the detected temperature is low, the portion to be heated is moved forward and backward at high speed, and cooking can be started quickly. In addition, even if the heated object mounting portion comes into contact with the heated object mounting portion during the forward movement or backward movement, the heated object mounting portion is hot before grill cooking. Since it is not, no problem occurs.

(2) The cooking cooker with a grill according to the present invention is provided with a grill storage having an opening on the front surface, and the heated object placing portion on which the heated object is placed is taken in and out through the opening. It ’s a cooker with a grill.
A drive unit that moves the heated object mounting portion in the front-rear direction between a storage position that is stored in the grill and a delivery position that is fed forward from the storage position through the opening. An operation unit that is operated to move the heated object mounting unit forward to the delivery position and retracted to the storage position, and a temperature detection unit that detects the temperature of the grill storage. A control unit that controls the drive unit based on the operation of the operation unit and the detection temperature detected by the temperature detection unit is provided.
When the detection temperature is high, the control unit determines the delay time from the operation of the operation unit to the start of the movement of the object to be heated by the drive unit based on the detection temperature. Is longer than when the detection temperature is low.

According to the present invention, for example, after the grill cooking is completed, the cooked object to be heated is taken out, or the heated object placing portion is moved forward to the delivery position in order to check the cooking condition during the grill cooking. Or, when the heated object placing part is moved backward to the storage position after checking the cooking condition, the temperature detected by the temperature detection unit of the grill storage is high, so that the heated object placing part is also at a high temperature. If there is, after operating the operation unit to move the object to be heated forward or backward, the forward movement or the backward movement is started with a long delay time. In this way, when the detection temperature of the grill storage is high, such as after the grill cooking is completed or during the grill cooking, the heated object placing portion heated in the grill storage has a delay time from the operation by the operation unit to the start of movement. Since the length is long, the user can afford to move his / her hand or body away from the moving path of the heated object placing portion, and can prevent the user from coming into contact with the hot object placed portion.

Further, for example, when the object to be heated is moved forward to the delivery position to load the food before the grill is cooked, and then the object to be heated is moved backward to the storage position, the grill storage is used. Since the detection temperature of the above is low, the forward movement and the backward movement of the object to be heated portion are started with a short delay time after operating the operation portion, and cooking can be started promptly. In addition, even if the heated object mounting portion comes into contact with the heated object mounting portion during the forward movement or backward movement, the heated object mounting portion is hot before grill cooking. Since it is not, no problem occurs.

(3) In a preferred embodiment of the present invention, in the invention of the above (1), the control unit sets the speed of the movement of the object to be heated by the drive unit to a detection temperature of a predetermined temperature or higher. When it is high, the speed is lowered as compared with when the detection temperature is lower than the predetermined temperature.

According to this embodiment, when the temperature detected by the grill storage by the temperature detecting unit is a high temperature equal to or higher than a predetermined temperature, the moving portion of the object to be heated is moved as compared with the case where the detected temperature is lower than the predetermined temperature. To slow down the speed of the cooked object, for example, to take out the cooked object to be cooked after the grill cooking is completed, or to check the cooking condition during the grill cooking, the heated object placing portion is sent out and advanced to the position. When moving, or when moving the heated object mounting part backward to the storage position again after checking the cooking condition, when the detection temperature of the grill is high and the temperature is higher than the predetermined temperature, the heated object is placed. Assuming that the placing portion is also hot, the placed portion to be heated is moved forward or backward at a low speed. Further, when the heated object placing portion is moved forward to the delivery position to load the food before grill cooking, and then the heated object placing portion is moved backward to the storage position, the grill storage is detected. When the temperature is low and lower than the predetermined temperature, the object to be heated is moved at high speed.

(4) In a preferred embodiment of the present invention, in the invention of the above (2), in the control unit, after the operation unit is operated, the drive unit starts the movement of the object mounting unit to be heated. When the detection temperature is as high as a predetermined temperature or higher, the delay time up to is made longer than when the detection temperature is lower than the predetermined temperature.

According to this embodiment, when the temperature detected by the temperature detection unit in the grill is higher than the predetermined temperature, the operation unit is operated after the operation unit is operated as compared with the case where the detection temperature is lower than the predetermined temperature. Since the delay time until the heated object mounting portion starts the forward movement or the backward movement is increased, for example, to take out the cooked object to be heated after the grill cooking is completed, or to cook during the grill cooking. When moving the heated object placing part forward to the sending position to check the condition, or when moving the heated object placing part backward to the storage position after checking the cooking condition, the grill storage When the detected temperature of the above is high and is equal to or higher than the predetermined temperature, it is assumed that the object to be heated is also high temperature, and a long delay time is required after operating the operation unit to move the object to be heated forward or backward. The forward movement or the backward movement is started with. Further, when the object to be heated is moved forward to the delivery position to load the food before the grill is cooked, and then the object to be heated is moved backward to the storage position, the grill is detected. When the temperature is low and the temperature is lower than the predetermined temperature, the forward movement and the backward movement of the object to be heated are promptly started with a short delay time after operating the operation unit.

(5) In another embodiment of the present invention, the control unit includes a notification unit that is controlled by the control unit and notifies the movement of the object to be heated by the drive unit, and the control unit detects the detection. The mode of notification by the notification unit when the temperature is high and the mode of notification by the notification unit when the detection temperature is low are different.

According to this embodiment, when the operation unit is operated in order to move the object to be heated forward or backward, the notification is made in a different manner according to the temperature detected by the temperature detection unit of the grill. Therefore, the user can recognize whether or not the moving portion to be heated has a high temperature, and it becomes easy to avoid contact with the portion to which the object to be heated has a high temperature.

(6) In still another embodiment of the present invention, the notification by the notification unit is a voice notification.

According to this embodiment, the content of the notification can be understood instantly, the situation can be grasped quickly and accurately, and it becomes easier to avoid contact with the hot object mounting portion.

It is provided side by side in. Further, above each point fire extinguishing button 10 and 11, thermal power adjusting levers 12 and 13 are arranged so as to be movable left and right in order to adjust the amount of gas supplied to the burners 8 and 7 to adjust the thermal power. There is.

Further, a battery case 16 for accommodating a battery as a power source for the built-in control unit 15 (see FIG. 2) and the like is provided on the lower left side of the front surface of the gas stove 1 with a grill.

In this embodiment, as shown in FIGS. 2 to 4, a pair of left and right fixed rails 24 are fixedly arranged horizontally in the front-rear direction in the lower part of the grill storage 5. A pair of intermediate rails 25 are engaged and supported by the pair of fixed rails 24 so as to be slidable back and forth, and a pair of movable frames 21 are engaged with the pair of intermediate slide rails 25 so as to be slidable back and forth. It is jointly supported.

The grill plate 22 as a mounting portion for the object to be heated is mounted and supported so as to straddle a fixed position of a pair of movable frames 21, and an opening on the front surface of the grill storage 5 is opened and closed at the front end of the movable frames 21. The grill doors 23 are connected in an upright position. Since the grill plate 22 is automatically taken in and out as described later, the front surface of the grill door 23 is not provided with a handle for manually taking in and out the grill plate 22.

Gear motors 26 that move the grill pan 22 in the front-rear direction and reduce the rotation of the stepping motor to output are installed on the left and right sides of the inner part of the grill storage 5, and are driven to rotate in the forward and reverse directions by each gear motor 26. A screw shaft 27 as a shaft is arranged in parallel with the fixed rail 24.

Nuts 28 screwed to the screw shaft 27 are connected to the left and right of the back end portion of the movable frame 21, and are supported by the movable frame 21 as a support as the screw shaft 27 rotates in the forward and reverse directions. The storage position where the grill plate 22 is stored in the grill storage 5 and the opening of the grill storage 5 is closed by the grill door 23, and the grill plate 22 is sent forward and largely exposed to the outside of the grill storage 5. It is configured to move in the front-rear direction over the delivery position. The object to be heated is placed on the grill plate 22 via a grill (not shown). The object to be heated may be placed directly on the grill plate 22.

The left and right gear motors 26, screw shafts 27, nuts 28, rails 24, 25, and the like constitute a drive unit that moves the grill pan 22 in the front-rear direction.

The moving position of the grill plate 22 is detected as the rotation amount of the stepping motor, and when the grill plate 22 reaches the set delivery position and storage position, the operation of the stepping motor is automatically stopped.

Further, a stopper 29 with which the nut 28 comes into contact is provided at the front end of the screw shaft 27, and even if the grill pan 22 moves forward beyond a predetermined delivery position, the nut 28 comes into contact with the stopper 29. Further forward movement of the grill plate 22 is prevented. Further, when it is detected that the forward movement of the grill pan 22 is prevented from abutting and the load current of the gear motor 26 is increased, the forward drive of the gear motor 26 is automatically stopped.

In the gas stove 1 with a grill of this embodiment, as shown in FIG. 2, the delivery switch 31 as an operation unit operated to send the grill plate 22 to the front delivery position and the grill plate 22 are grilled. The storage switch 32 as an operation unit operated to retract to the storage position in the storage 5, the temperature sensor 33 as a temperature detection unit for detecting the temperature of the grill storage 5, and the operations of the switches 31 and 32. It includes a control unit 15 that controls the gear motors 26 and 26 of the drive unit based on the temperature detected by the temperature sensor 33, and a notification unit 34 that notifies the movement of the grill pan 22.

As shown in FIG. 1, the delivery switch 31 and the storage switch 32 are arranged below the point fire extinguishing button 11 of the grill burner 7 on the front right side of the gas stove 1 with a grill.

In response to the operation of the delivery switch 31, the control unit 15 activates the gear motors 26 and 26 in the forward rotation to advance the grill pan 22 and move it from the storage position to the delivery position. Further, in response to the operation of the storage switch 32, the gear motors 26 and 26 are reversely activated to retract the grill plate 22 and move it from the delivery position to the storage position.

In this way, the control unit 15 controls the drive of the gear motors 26 and 26 in response to the one-touch operation of the switches 31 and 32 to advance the grill pan 22 from the storage position to the delivery position, or to deliver the grill pan 22. Retreat from the grill position to the storage position.

The temperature sensor 33 is composed of, for example, a thermistor, and is provided at an appropriate position in the grill storage 5 to detect the temperature of the grill storage 5. The grill plate 22 is usually stored in a storage position in the grill storage 5 except when placing ingredients before cooking, checking the cooking condition during cooking, or taking out ingredients after cooking. The temperature of the grill plate 22 corresponds to the temperature inside the grill storage 5. Therefore, when the detection temperature of the grill storage 5 detected by the temperature sensor 33 is high, the grill plate 22 is also often high.

The control unit 15 controls the moving speed of the grill plate 22 supported by the movable frame 21 by the gear motors 26, 26 in the front-rear direction based on the temperature detected by the temperature sensor 33. In this embodiment, when the detection temperature is a high temperature of 60 ° C. or higher as a predetermined temperature, the moving speed is made slower than when the detection temperature is a low temperature of less than 60 ° C. The predetermined temperature is not limited to 60 ° C., and may be another temperature.

The notification unit 24 moves to the grill plate 22, that is, the grill plate 22 stored in the grill storage 5 moves forward to the delivery position, and the grill plate at the delivery position outside the grill storage 5 22 notifies each of them that they move backward to the storage position in the grill storage 5.

The control unit 15 controls the notification by the notification unit 34 based on the detection temperature by the temperature sensor 33. Specifically, when the detection temperature is a high temperature of 60 ° C. or higher as a predetermined temperature. The mode of notification is different depending on whether the temperature is lower than 60 ° C.

In this embodiment, since the temperature inside the grill storage 5 is low before grill cooking is performed, the temperature of the grill plate 22 is also low. In this case, the operating speed of the gear motor 26 is set to "high speed". The grill plate 22 moves quickly. Further, for example, during grill cooking or immediately after cooking, the temperature inside the grill storage 5 is high, so that the temperature of the grill plate 22 is also high. In this case, the operating speed of the gear motor 26 is set to "low speed" and becomes hot. The grill plate 22 is slowly moving.

For example, when the detection temperature θ of the grill storage 5 is less than the predetermined temperature θ0 (60 ° C.) (θ <θ0), the moving speed of the grill pan 22 is set to, for example, 15 mm / sec, and the detection of the grill storage 5 When the temperature θ is equal to or higher than the predetermined temperature θ0 (60 ° C.) (θ ≧ θ0), the moving speed of the grill pan 22 is lower than that when the temperature is less than the predetermined temperature θ0 (60 ° C.), for example, 10 mm / It is considered to be seconds.

Further, the control unit 15 controls the notification unit 34 in response to the switch operation and the detection temperature of the grill storage 5 detected by the temperature sensor 33, and the notification unit 34 controls the notification unit 34, for example, as follows. Notify by voice message.

That is, when the detected temperature θ of the detected grill storage 5 is less than the predetermined temperature θ0 (60 ° C.) (θ <θ0), for example, a voice message such as “The grill plate moves” is sent to the notification unit 34. If the detected temperature θ of the grill storage 5 detected is greater than or equal to the predetermined temperature θ0 (60 ° C) (θ ≧ θ0), for example, “The grill plate is moving. It is hot. A voice message such as "Please be careful." Is output from the notification unit 34 to alert the user.

As described above, the mode of notification differs depending on whether the detection temperature θ of the grill storage 5 is less than the predetermined temperature θ0 (60 ° C.) and the predetermined temperature θ0 (60 ° C.) or higher, that is, the content of the voice message. Therefore, the user can recognize whether the moving grill plate 22 and the grill door 23 at the front end thereof are hot or not, and avoid contact with the high temperature grill plate 22 and the grill door 23. It becomes easy.

As described above, according to the present embodiment, the grill pan 22 is automatically moved forward from the storage position to the delivery position by one-touch operation of the delivery switch 31 and the storage switch 32, and is automatically delivered. Since it moves backward from the position to the storage position, it is convenient because the user does not have to manually put in and take out the grill plate 22.

Moreover, when the detection temperature of the grill storage 5 detected by the temperature sensor 33 is a high temperature of 60 ° C. or higher, which is a predetermined temperature, the temperature of the grill pan 22 is also high, and the detection temperature of the grill storage 5 is 60 ° C. The moving speed for moving the grill plate 22 forward to the delivery position and the moving speed for moving the grill plate 22 backward to the storage position are lower (for example, 10 mm / sec) than when the temperature is lower than that. To.

Therefore, for example, when the grill plate 22 is sent out and moved forward to the position to take out the cooked object to be cooked after the grill cooking is completed, or to check the cooking condition during the grill cooking, or to change the cooking condition. After seeing, when the grill plate 22 is moved backward to the storage position again, the temperature detected by the grill storage 5 by the temperature sensor 33 is high, and when the temperature is equal to or higher than the predetermined temperature, the temperature of the grill plate 22 is also high. The grill plate 22 moves forward or backward at a low speed. As a result, the user can afford to move his / her hand or body away from the movement path of the grill plate 22 and the grill door 23 at the front end thereof, and makes contact with the high temperature grill plate 22 and the grill door 23 at the front end that move forward or backward. It can be suppressed.

On the other hand, when the grill plate 22 is moved forward to the delivery position to load the food before the grill is cooked, and then the grill plate 22 is moved backward to the storage position, it is before cooking, so the temperature sensor 33 is used. When the detected temperature of the detected grill storage 5 is low and lower than a predetermined temperature, the temperature of the grill plate 22 is also low, and the forward and backward movement speeds of the grill plate 22 are increased (for example, 15 mm / sec). , You can start grill cooking promptly. Further, even if the grill plate 22 may come into contact with the grill plate 22 or the grill door 23 momentarily while the grill plate 22 is being moved, the grill plate 22 or the like is at a low temperature and will not be burned.

Further, when the detection temperature of the grill storage 5 detected by the temperature sensor 33 is a high temperature of 60 ° C. or higher, which is a predetermined temperature, when the grill plate 22 is moved forward or backward, that fact is notified by voice. Therefore, the user can instantly grasp that the high temperature grill plate 22 moves forward or backward, and more reliably avoids contact with the high temperature grill plate 22 or the grill door 23. be able to.

(Embodiment 2)
FIG. 5 is a schematic configuration diagram corresponding to FIG. 2 of another embodiment of the present invention.

In this embodiment, the structure itself for moving the grill pan 22 in the front-rear direction between the delivery position and the storage position is the same as that in the above embodiment.

In this embodiment, the control unit 15'delays the start of the gear motor 26 based on the temperature detected by the grill storage 5 detected by the temperature sensor 33 each time the grill pan 22 moves forward or backward. I do.

For example, when the detected temperature θ of the detected grill storage 5 is a low temperature of less than 60 ° C. as a predetermined temperature θ0 (θ <θ0), the delay from the operation of the transmission switch 31 or the storage switch 32 to the start of the motor The time is set to, for example, 0.2 seconds or less, and the grill plate 22 starts moving immediately after the switch operation. Further, when the detected temperature θ of the detected grill storage 5 is a high temperature of the predetermined temperature θ0 (60 ° C.) or higher (θ ≧ θ0), the delay time is longer than when the detected temperature θ is lower than the predetermined temperature θ0. For example, it is set to 3 seconds, and after the switch operation, the grill plate 22 starts moving with a time lag.

According to this embodiment, for example, when the grill plate 22 is sent out and moved forward to the position in order to take out the cooked object to be cooked after the grill cooking is completed or to check the cooking condition during the grill cooking. Alternatively, when the grill plate 22 is moved backward to the storage position again after checking the cooking condition, the temperature detected by the grill storage 5 by the temperature sensor 33 is high, and when the temperature is higher than the predetermined temperature, the temperature of the grill plate 22 is high. Assuming that the temperature is also high, the delay time from the operation of the delivery switch 31 or the storage switch 32 to the start of the forward movement or the backward movement of the grill pan 22 is set to be long, for example, 3 seconds.

As a result, the user can afford to move his / her hand or body away from the movement path of the grill plate 22 and the grill door 23 at the front end thereof, and makes contact with the high temperature grill plate 22 and the grill door 23 at the front end that move forward or backward. It can be suppressed.

On the other hand, when the grill plate 22 is moved forward to the delivery position to load the food before the grill is cooked, and then the grill plate 22 is moved backward to the storage position, it is before cooking, so the temperature sensor 33 is used. When the detected temperature of the detected grill storage 5 is low and lower than a predetermined temperature, it is assumed that the temperature of the grill plate 22 is also low, and the grill plate 22 moves forward or backward from the operation of the delivery switch 31 or the storage switch 32. The delay time until the start of movement can be shortened, for example, 0.2 seconds or less, and grill cooking can be started promptly.

The moving speed of the grill pan 22 in this embodiment is set to a constant "high speed" (for example, 15 mm / sec) regardless of the detection temperature of the grill pan 5, but the grill pan 5 is similar to the above embodiment. It may be switched between high and low according to the detection temperature.

(Other embodiments)
The present invention can also be carried out in the following forms.

(1) As shown in FIG. 6, a cover 36 extending in the front-rear direction is provided to cover each of the left and right screw shafts 27 and nuts 28 as drive shafts for driving the grill pan 22 by screw feeding. The oil or juice leaked from the plate 22 may be prevented from adhering to the screw shaft 27. Further, each gear motor 26 may be covered together.

(2) As shown in FIG. 7, the grill pan 22 can be moved in the front-rear direction by a single screw shaft 27 arranged in the center in the left-right direction.

(3) As shown in FIG. 8, the grill door 23 is pivotally supported at the lower part of the front end of the grill storage 5 so as to be undulating and rotatable around the fulcrum p, and the grill door 23 is rotated in the upright direction by a torsion spring or the like. Momentum. The front end of the movable frame 21 that supports the grill plate 22 that moves forward to the delivery position presses and rotates the grill door 23 to open the opening on the front surface of the grill storage 5. Further, the grill door 23 stands up and rotates following the front end of the movable frame 21 that supports the grill plate 22 that moves backward to the storage position, and closes the opening on the front surface of the grill storage 5.

According to this, when the grill plate 22 is in the delivery position, the grill door 23 enters below the grill plate 22, so that the grill door 23 can be loaded and unloaded with foodstuffs. It can be done easily without being disturbed.

(4) As a notification unit that notifies the user of the movement of the grill plate 22, an electronic buzzer that emits alarm sounds having different cycles according to the detection temperature of the grill storage 5 can also be used. In this case, when the detected temperature of the grill storage 5 is lower than a predetermined temperature, a notification sound having a long cycle (for example, "pee-pee-pee") is used to notify the detected temperature of the grill storage 5. When the temperature is higher than a predetermined temperature, the user's attention can be drawn by notifying with a notification sound having a short cycle (for example, "pip-pip" or "pip-pip").

(5) In the above embodiment, the movement speed or movement start of the grill plate 22 is performed in two stages of whether the detection temperature of the grill storage 5 detected by the temperature sensor 33 is equal to or higher than the predetermined temperature or lower than the predetermined temperature. Although the delay time until is different, it can be carried out in three or more stages.

For example, the temperature detected by the temperature sensor 33 is divided into three stages according to the first predetermined temperature and the second predetermined temperature higher than that, and the temperature detected by the temperature sensor 33 is determined.
When the temperature is equal to or higher than the second predetermined temperature, the moving speed of the grill plate 22 is set to a low speed, or the delay time until the start of moving the grill plate 22 is set to a long first delay time, and the temperature detected by the temperature sensor 33 is the first. When the temperature is equal to or higher than the predetermined temperature and lower than the second predetermined temperature, the moving speed of the grill plate 22 is set to a medium speed faster than the low speed, or the delay time until the start of movement of the grill plate 22 is shorter than the first delay time. When the delay time is 2 and the temperature detected by the temperature sensor 33 is less than the first predetermined temperature, the moving speed of the grill plate 22 is set to be faster than the medium speed, or the delay until the start of movement of the grill plate 22 is set. The time may be a third delay time shorter than the second delay time.

In addition, using a function, the higher the temperature detected by the temperature sensor 33, the slower the moving speed of the grill plate 22 or the longer the delay time until the start of movement of the grill plate 22 is changed in multiple stages. You may let me.

(6) The user comes into contact with the hot grill plate 22 or the grill door 23 when the grill plate 22 or the like moves forward to the delivery position, and the grill plate 22 or the like moves backward to the storage position. Since it is more than the time, the speed of forward movement to the sending position when the detection temperature of the grill storage 5 is high is "low speed", and the speed of backward movement to the storage position when the detection temperature of the grill storage 5 is high is high. Is set to "medium speed", and when the detection temperature of the grill storage 5 is low, the speed of forward movement to the delivery position and the speed of backward movement to the storage position are both set to "high speed", and the grill plate 22 is moved to the storage position. It is also possible to move as quickly as possible.

(7) If either the sending switch 31 or the storage switch 32 is operated while the grill plate 22 is moving, the advancing / retreating movement is stopped, and if the sending switch 31 is operated next, the feeding switch 31 is sent. When the forward movement to the position is performed and the storage switch 32 is operated instead of the delivery switch 31, the backward movement to the storage position may be performed.

According to this, the delivery switch 31 is operated during grill cooking to move the grill plate 22 forward to the delivery position, and the delivery switch 31 or the storage switch 32 is moved to the position where the grill plate 22 is slightly exposed to the outside of the grill. Operate any of them to stop the movement, look into the grill plate 22 exposed to the outside of the grill to check the cooking condition, and if cooking is insufficient, operate the storage switch 32 to move the grill plate 22 to the storage position. When the food is moved backward and it is confirmed that the food is sufficiently cooked, the delivery switch 31 can be operated to easily perform an advance / retreat operation such that a large amount of food is continuously transmitted.

(8) As the drive unit for moving the grill pan 22 forward and backward in the front-rear direction, various forms can be used in addition to the screw feed structure described above. For example, as shown in FIG. 9, a rack gear 37 provided along a movable frame 21 is engaged with a pinion gear 38 driven forward and reverse by a gear motor 26 to occlude and move the grill plate 22 back and forth. It may have a pinion structure. Further, as shown in FIG. 10, the movable frame 21 is connected to a cord body 39 such as a chain or a wire wound so as to be driven and rotated in the forward and reverse directions by the gear motor 26, and the movable frame 21 is rotated in the forward and reverse directions of the cord body 39. A traction structure for traction-moving the grill plate 22 back and forth can be arbitrarily used.

(9) When the grill pan 22 is driven back and forth with the rack and pinion structure or the traction structure described above, by interposing a slip clutch in the rotation transmission system of the drive mechanism, a trouble occurs in the drive mechanism and the switch is switched. When the grill plate 22 cannot be moved in and out by the operation, the grill plate 22 can be manually forcibly moved in and out. In this case, it is necessary to provide a handle having a heat insulating structure on the front surface of the grill door 23 of the grill plate 22.

(10) The specification may be such that the notification unit 34 is not provided.

(11) The cooker with a grill of the present invention is not limited to a gas-combustion type cooker provided with a stove portion, but can be similarly applied to an electric heater and an electromagnetic cooker.

The present invention is not limited to each of the above embodiments, and various modifications can be added within the scope of the present invention.
