The tray 30 is pushed and urged in the forward direction via the shaft 7. still,
As described later, the force of the tension spring 13 is
8 with sufficient force to open the pan 3
When the zero plate portion 31 is locked, the force is set such that the tray 30 cannot be moved only by the urging force.

On the bottom surface of the heating chamber 10 near the entrance, there is provided a front locking portion 32 which comes into contact with a plate step portion 31 provided on the bottom surface of the receiving tray 30 and regulates the forward movement (drawing direction) of the receiving tray 30. The receiving tray 30 is locked to the front locking portion 32 in a state where the tray 30 is pulled out from the heating chamber 10 to the maximum. The receiving tray 30 is mounted on the left and right ends thereof by guide portions (not shown) provided on the left and right wall surfaces of the heating chamber 10 so as to be able to move forward and backward. When the tray 30 is to be removed from the heating chamber 10, the handle 16 is grasped and lifted up, and the plate step 31 is removed from the front locking portion 32 and removed.

A resilient leaf spring 14 which abuts against a plate step 31 on the bottom of the pan 30 to restrict the forward movement of the pan 30 is provided at one end of the bottom of the heating cabinet 10 at the back. It is provided so as to be able to protrude and retract from a cutout hole in the bottom surface while being fixed to the outer bottom surface. The plate spring 14 locks the plate step portion 31 of the tray 30 so that the tray 30 is not accidentally jumped out of the heating chamber 10 while the tray 30 is stored in the heating chamber 10.

Next, the tray 3 in such a grill 1 will be described.
The storage and withdrawal operation of 0 will be described. When the pan 16 is pulled out of the heating chamber 10 by grasping the handle 16, the plate step 31 of the pan 30 is pulled out of the leaf spring 14 of the heating chamber 10, and the pan 30 slides on the bottom of the heating chamber 10 and is placed. The grill 20 is pulled out at the same time. The grill support frame 6 rotates counterclockwise as the U-shaped lower portion 3j is pulled out, as the U-shaped lower portion 3j is locked by the locking portion 8c during the drawing ((A) → (B) in FIG. 2). . And the grid support frame 6
By rotating around the fulcrum shaft 6b to an angle regulated by the stopper 3g, a step 6d on which the grill 20 is placed is provided.
Is moved from directly above the saucer 30 to the oblique front. In this case, since the interlocking arm 15 links the front and rear grille support frames 6, the mounting surface of the grill 20 moves forward and lowers while being kept horizontal. When the grill supporting frame 6 is rotated to the angle regulated by the stopper 3g, the engagement of the engagement portion 8c with the U-shaped lower portion 3j is released. Furthermore, the saucer 30
Is pulled out, the tension spring 13 acting on the connecting lever 35 is pulled out.
The contact portion 7a of the shaft 7 moves forward together with the tray 30 while contacting the rear portion of the tray 30, and the roller 9
b, 9b advance in the long slot 40 (FIG. 2 (B) →
(C)). At the same time, the grill door 18 is pushed by the forward movement of the connecting lever 35, and is pivotally opened from (A) to (B) in FIG.
The heating chamber 10 is fully opened in the middle of sliding, and is rotated and stored above the front entrance of the heating chamber 10. When the grill door 18 is fully opened, the contact portion 7a of the shaft 7 cannot move forward, and as the tray 30 is pulled out, the saucer 30 separates from the contact portion 7a of the shaft 7 and moves to the front locking portion 32 of the heating chamber 10. The tray 30 is pulled out integrally with the grill 20 to a position where the plate step 31 of the tray 30 is locked.

On the other hand, when the handle 16 is pushed in while the tray 30 is pulled out, the tray 30 first slides backward, and the rear part of the tray 30 is brought into contact with the shaft 7 at a position close to the rear of the heating chamber 10. It comes into contact with the contact portion 7a. When the tray 30 is further pushed in the depth direction of the heating chamber 10 as it is, the connecting lever 35 is retracted together with the tray 30 by the pushing force via the shaft 7 while resisting the urging force of the tension spring 13. To this end, the grill door 18 is supported by a locking pin 18c as a fulcrum.
This time, it is rotated in the direction from (b) to (a) in FIG. Further, as the tray 30 is fed into the heating chamber 10, the U-shaped lower part 3j of the grill support frame 6 comes into contact with the contact portion 8b of the fixing member 8, and the pressing force of the fixing member 8 is applied by the pushing force. The contact portion 8b pushes the U-shaped lower portion 3j of the grid support frame 6, and the pushing force acts as a turning force to the grid support frame 6, so that the grid support frame 6 is pressed.
Is rotated clockwise, and the step 6d is rotated from obliquely forward to a position almost directly above the fulcrum shaft 6b ((B) → (A) in FIG. 2). At the same time, at this position, the grill door 18 fully closes the entrance of the heating chamber 10 ((A) in FIG. 1). In this manner, the grill 20 is configured such that the saucer 30 is
When the storage surface is placed inside the heating chamber 10, the front surface of the mounting surface passes through the entrance 10 a of the heating chamber 10 and is then pushed to the rearward position of the heating chamber 10. It is moved above the heating chamber 10 while moving backward while being kept horizontal. And the grill 20 placed on the step 6d
Is moved upward, the plate step 31 of the tray 30 is locked by the leaf spring 14 of the heating chamber 10, and the state where the tray 30 is placed in the heating chamber 10 is maintained.

Next, the heating cooking will be described. During combustion, high-temperature combustion exhaust gas accumulates in the upper portion of the heating chamber 10 and overflows into the communication port 70 at the rear of the heating chamber 10, and then rises in the exhaust chamber 60 by a draft effect. In this case, the object to be cooked placed on the mounting surface of the grill 20 which is slightly higher than the upper end of the opening of the communication port 70 is burned by the convection of the high-temperature combustion exhaust gas filling the upper part of the heating chamber 10. By heating, it is heated to every corner and cooked well. In other words, the object to be cooked is held in a high-temperature zone in which hot air is trapped above the heating cabinet 10 by the elevating mechanism for elevating and lowering the grille 20, so that the object is cooked efficiently.

As described above, according to the gas grill of this embodiment, the abutting portion 8b of the fixing bracket 8 abuts on the U-shaped lower portion 3j of the grill support frame 6 while the tray 30 is being pushed in. When the mesh supporting frame 6 is rotated, the grill 20 is raised, and the locking portion 8c of the fixing member 8 comes into contact with the U-shaped lower portion 3j of the grill supporting frame 6 during the drawing, so that the grill supporting frame 6 is pulled. 6 is rotated to lower the grill 20. Therefore, as the tray 30 is put in and taken out, the grill 20 can be moved up and down without fail.

Further, since the placing surface of the grill 20 is lowered while moving the grill 20 forward with respect to the tray 30 to be drawn out, it is easy to put in and out and return the object to be cooked. Compared with FIG. 5 showing the conventional example, the draw-out length from the grill door 18 is increased from L2 to L1, and the height to the upper end of the entrance 10a is increased from H2 to H1, so that it is easy to take in and out and return the food. become.

Further, when the object to be cooked is placed on the grill 20 and the saucer 30 is stored in the heating chamber 10, the grill 20 which was at a low position at the time of taking out the entire cooking object is located on the upper side of the heating chamber 10. Since it is pushed up to a height high enough to enter the high-temperature zone formed, the object to be cooked can be efficiently cooked even with a thick object to be cooked. In particular,
In the case of an object to be cooked having a low moisture content, the object to be cooked is sufficiently heated by the hot air in the heating chamber 10 and there is no need to turn the object to be cooked upside down during heating and cooking. In addition, since the pan 30 is not directly heated by the radiant heat of the burner 41, the burnt fat accumulated in the pan 30 does not overheat and ignite, and there is no need to fill the pan 30 with water. Become.

Further, when the pan 30 is located immediately before the completion of storage or immediately after the drawer, that is, when the pan 30 is at the back of the heating chamber 10, the grill 20 is raised and lowered and held at a predetermined position. Even if there is an object to be cooked, the tray 30 can be smoothly taken in and out without being caught in the entrance 10a of the heating chamber 10 during taking in and out.

Next, a second embodiment will be described with reference to FIG. (X) of FIG.
0 indicates the stored position, and (Y) indicates the position immediately before storing the tray 30 or the position immediately after the start of drawing. This second
In the embodiment, the same portions as those in the first embodiment are denoted by the same reference numerals in the drawings, and redundant description will be omitted.
In the first embodiment, in order to lower the grill 20 by rotating the grill supporting frame 6 in the middle of drawing, the locking portion of the fixture 8 abutting on the U-shaped lower portion 3j of the grill supporting frame 6. In contrast to the arrangement of the return spring 8c, in the second embodiment, at the position immediately before storage, a return spring that abuts against the rear portion of the grill 20 and urges the grill support frame 6 in the pulling-out direction (leftward in the drawing). 80 is provided. In the second embodiment, the locking portion 8c of the fixing bracket 8 may be omitted, and the grill supporting frame 6 may be rotated only by the return spring 80 when the tray 30 is pulled out. The urging force of the return spring 80 is added to the force of the tension spring 13 described above, and when the plate step 31 of the pan 30 is locked by the leaf spring 14, the urging force of the pan 3
The strength is set to such a degree that 0 cannot be moved.

Next, the operation of taking the tray 30 in and out of the heating chamber 10 will be described. First, grasp the handle 16 and set the saucer 3
0 is pulled out from the heating chamber 10 and the catch by the plate spring 14 is released from the dish step 31 of the saucer 30, and since the griddle 20 is urged by the return spring 80 in the direction in which the saucer 30 is pulled out, the saucer 30 7, the grill supporting frame 6 is rotated about the fulcrum shaft 6b to an angle regulated by the stopper 3g, and the grill 20 moves to a lower position in front of the tray 30 (FIG. 7). (Y)). On the other hand, when the handle 16 is pushed in from the state in which the tray 30 is pulled out,
Abuts on the lower U-shaped lower portion 3j of the grid support frame 6, the pushing force acts as a turning force on the grid support frame 6, and the grid support frame 6 rotates clockwise in the drawing. As a result, the grill 20 moves to the rear high position ((Y) → (X) in FIG. 7).
In the retracted position, the leaf spring 14 locks the plate step 31 to keep the tray 30 in the retracted state, and the return spring 80 abuts against the rear of the grill 20 to prepare the grid support frame 6 for the next drawer. 30
In the pull-out direction. As described above, the second
According to the gas grill of the embodiment, the grill 20 can be reliably moved up and down as the tray 30 is taken in and out.

Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments at all, and it goes without saying that the present invention can be implemented in various modes without departing from the spirit of the present invention. It is. For example, the burner 41 may be a burner for double-side baking that does not require turning over the object to be cooked. Alternatively, a burner of another combustion type may be used.

A grill that heats and cooks the object directly by the radiant heat of the burner may be used instead of heating and cooking with the hot air stored in the heating chamber 10.

In the embodiment, the supporting plate 3 and the grill supporting frame 6 supported by the supporting plate 3 correspond to the "elevating mechanism" of the present invention, and the U-shaped lower portion 3j of the grill supporting frame 6 is The contact portion 8b of the fixture 8 corresponds to "contact means", the locking portion 8c corresponds to "locking means", and the return spring 80 corresponds to "biasing means".
