In this embodiment, in the form in which the door 2 and the support rod 9 are connected by the grill 7, the back side of the grill 7 (the rear side from the support rod 9).
Door 2 with the relatively heavy food B placed on top
It is characterized in that when closing the door, the phenomenon that the grill 7 is disengaged from the door 2 side and the front side of the grill 7 jumps upward does not occur. Specifically, projecting pieces 20, 20 are provided at both left and right ends below the inner surface of the door 2. The protruding pieces 20, 20 project substantially perpendicularly to the inner surface of the door 2 so that when the door 2 is tilted forward about the fulcrum 2a, it takes a posture along the vertical direction.
The protruding pieces 20, 20 are provided with laterally substantially T-shaped cutout holes 21, 21 as described below for detachably hooking both corners on the door side of the frame 7a of the grill 7. The cutout holes 21 and 21 are formed substantially along the horizontal direction in a state where the projections 20 and 20 are oriented substantially vertically by tilting the door 2 forward, and the cutout holes 21 and 21 are formed in the frame 7 a of the grill 7.

When the door 2 is opened or closed when no food is placed on the grill 7 or when light food is placed on the grill 7, the first hook portions 23 are located on the door side of the frame 7 a of the grill 7. It is a hook to prevent it from coming off easily. The second hook portions 24, 24 are provided to prevent the door-side portion of the frame portion 7a of the grill 7 from easily coming off when the door 2 is opened and closed while heavy food is placed on the grill 7. It is a catch. Third hook part 25, 2
Reference numeral 5 denotes a hook for preventing the door-side portion of the frame portion 7a of the grill 7 from being easily removed when the door 2 is closed in a state in which heavy food is placed on the back side of the grill 7. . Next, an opening / closing operation of the door 2 depending on a difference in how to place the food will be described. First, as shown in FIG. 2, in a state where no food is placed or a state where a light food is placed, the entire grill 7 does not sink down, and the grill 7 does not sink.
Of the frame portion 7a is hooked on the first hook portions 23, 23 of the cut holes 21, 21 of the projecting pieces 20, 20. When the user attempts to close the door 2 from this state, the grill 7 is pulled inward by the restoring force of the coil springs 10 and 10 and the door 2 is pulled, so that the door 2 is closed as shown in FIG. At this time, the door-side portion of the frame portion 7a of the grill 7 is hooked on the first hook portions 23 of the cut holes 21 and 21 and is in contact with the inner side of the first hook portions 23. In addition, the door side portion of the frame portion 7a of the grill 7 does not have to move to the insertion / extraction ports 22,22. Therefore, the grill 7 does not come off from the cut holes 21 and 21. Further, as shown in FIG. 4, when the relatively heavy food B is placed in front of or at the center of the grill 7 in a well-balanced manner, the entire grill 7 sinks below and the frame of the grill 7 The door-side portion of the portion 7a is the protruding piece 20,
The second hook portions 24, 24 of the 20 cut holes 21, 21
Caught on In this state, since the weight of the food B is stronger than the restoring force of the coil springs 10, 10,
The grill 7 is not drawn in. When the user attempts to close the door 2 from this state, as shown in FIG.
The door side portion of the frame portion 7a is the second hook portion 24,2.
4 comes into contact with the back side, and the door portion of the frame portion 7a of the grill 7 does not move toward the insertion / extraction ports 22, 22 with the force to push up the door 2, and the grill 7 is pushed into the back. At the same time, the door 2 is closed as shown in FIG. Therefore, the grill 7 does not come off from the cut holes 21 and 21. Further, as shown in FIG. 7, in a state where the relatively heavy food B is placed in the back of the grill 7, the back side of the grill 7 sinks downward with the support rod 9 as a center, and The side is floating up and the frame 7 of the grill 7
The door side portion in FIG.
1, 21 are hooked on the third hook portions 25, 25. In this state, the weight of the food B is the coil spring 1
Since it is stronger than the restoring force of 0, 10, the grill 7 is not drawn into the back. When the user attempts to close the door 2 from this state, as shown in FIG. 8, the door-side portion of the frame portion 7 a of the grill 7 comes into contact with the first hook portions 23, 23 on the side of the door. With the force to push up the door 2, the door-side portion of the frame portion 7 a of the grill 7 does not move toward the insertion / extraction openings 22, 22, and the grill 7 is pushed inward.
As shown in FIG. 9, the door 2 is closed. Therefore,
The grill 7 does not come off the cut holes 21 and 21.
In this way, by devising the shape of the cut holes 21 and 21 of the protruding pieces 20 and 20, even when the door 2 is closed in a state where a heavy food is placed in the back of the grill 7 with an improper balance, the protrusion of the door 2 can be achieved. The phenomenon that the grill 7 is detached from the pieces 20 and 20 does not occur, and the food can be stored in the heating chamber 3 with a stable posture. Note that the present invention is not limited to only the above embodiment, and various applications and modifications can be considered. (1) In the above embodiment, as in the conventional example, it is assumed that the protruding pieces 20, 20 of the door 2 and the support rod 9 are connected by the grill 7; however, as shown in FIG. Net 7
The structure that allows easy and quick attachment and detachment, that is,
By devising the shape of the support rod 9, the support rod 9 is directly engaged with the projecting pieces 20, 20 of the door 2,
The present invention can be applied to a structure in which the grill 7 is hooked on the support bar 9 in the same manner as described above. (2) In the above embodiment, the heating chamber 3 and the grill 7 are formed into a shape close to a square, and the support rod 9 A structure in which the support points are arranged near the center in the depth direction of the heating chamber 3 can be employed. In this case, although the food tends to be placed on the grill 7 in an unbalanced state and is likely to be placed on the grill 7, a problem as in the conventional example is likely to occur. However, the above-described characteristic configuration of the present invention can surely prevent the problem. Therefore, it is more advantageous to apply the present invention to such an oven toaster.

According to the first to fifth aspects of the present invention, in the configuration in which the grill is taken in and out in conjunction with the opening and closing of the door and the opening angle of the door is regulated, the shape of the cutout hole of the projecting piece provided in the door is provided. By devising the method, even when closing the door with heavy food placed in the back of the grill with an improper balance, it is possible to avoid the phenomenon that the grill or the support rod comes off from the projection of the door, and The object can be stored in the heating chamber in a stable posture. In particular,
According to the fourth aspect of the invention, even if the door is closed and released by the resilient urging element, the door does not open freely. According to the fifth aspect of the present invention, the shape of the heating chamber or the grill is made to be close to a square in order to enable heating of a larger cooking product, and the support point of the support rod is set closer to the center in the depth direction of the heating chamber. Since it is assumed that it is located in
