It is placed on the grill 19 and stored in the cooking chamber 2.

As shown in FIG. 4, the grill 19 is formed by combining wire rods in a net shape, and has leg portions 19b integrally provided under a mounting surface portion 19a which spreads in a substantially horizontal direction. It is being touched. The lower end portion of the leg portion 19b is formed in a rectangular shape that substantially matches the inner surface shape of the top plate 18, and the leg portion 19b is mounted so as to be fitted into the top plate 18, thereby allowing the above-mentioned description. The placing surface portion 19a is adapted to be supported by the upper portion in the cooking chamber 2. In addition, in the placing surface portion 19a, three recesses 19c are formed side by side in the front-rear direction of the cooking chamber 2 and extend slightly in the left-right direction. By placing the fish F 1 in the concave portion 19c, the fish F 1 can be stably placed on the grill 19 without displacement.

A weight sensor 20 that detects the weight of the object to be heated based on the load acting on the rotary shaft 15 is provided on the lower end side of the rotary shaft 15. As is well known, the weight sensor 20 is composed of a fixed sensor plate and a movable sensor plate that is displaced according to the displacement of the rotary shaft 15 so as to detect a weight of an object to be heated from its oscillation frequency. It has become.

Now, the movable heaters 13 and 14 will be described in detail. The movable heaters 13 and 14 are, for example, sheathed heaters, and each of the movable heaters 13 and 14 includes an opening side (hereinafter, referred to as a front movable heater 13) and a back side (hereinafter, referred to as a back movable heater 14) in the cooking chamber 2, respectively. It is located at the top of the.

Of these, as shown in FIG. 2, the front movable heater 13 has left and right side wall portions 3 and 4 of the cooking chamber 2 at both ends of a heater main portion 13a that extends substantially completely in the cooking chamber 2 in the left-right direction. The shaft portions 13b and 13b respectively penetrating the front side upper portion of the above are integrally connected via curved portions 13c and 13c extending in a curved shape in the front-rear direction (see FIG. 1).

The shaft portions 13b and 13b of the front movable heater 13 are rotatably supported by the side wall portions 3 and 4, whereby the front movable heater 13 is shown by a solid line in FIG. As described above, the heater main portion 13a is retracted to the ceiling portion 6 of the cooking chamber 2, and from the retracted position as shown by a two-dot chain line, the heater main portion 13a is rotated clockwise in FIG. It is displaceable between the heating position and the lower part of the placing surface portion 19a. The shaft portion 13b is connected to the front heater motor 21 (illustrated only in FIG. 4) provided outside the cooking chamber 2, and thus the front heater motor 21 is driven to move the front side. The heater 13 is displaced between the retracted position and the heating position.

On the other hand, as shown in FIG. 3, the back side movable heater 14 extends in the cooking chamber 2 to the full extent in the left-right direction and is folded in triplicate so that both ends of the heater main portion 14 a are arranged in the cooking chamber 2. Shafts 14b, 14b penetrating the upper parts on the far side of the left and right side walls 3, 4 are integrally connected via connecting parts 14c, 14d. In this case, since the back movable heater 14 is configured by folding the heater main portion 14a in three, the heating output is larger than that of the front movable heater 13 described above, and the inside of the cooking chamber 2 is heated at the heating position. It goes around to the central part.

Similar to the front movable heater 13, the shaft portions 14b, 14b of the rear movable heater 14 are rotatably supported by the side wall portions 3, 4 and are shown by solid lines in FIG. It is displaceable between a retreat position retracted to the back wall portion 5 of the cooking chamber 2 and a heating position that wraps around the lower portion of the placing surface portion 19a of the grill 19. Finally, the back side movable heater 14 is also displaced between the retracted position and the heating position by driving the back side heater motor 22 (see FIG. 4).

The grill 19 is arranged at a position outside the rotation regions of the front movable heater 13 and the back movable heater 14. Further, in a normal state, the front movable heater 13 and the rear movable heater 14 are retracted to the retracted position so that they do not interfere with accommodation of the object to be heated.

As shown in FIG. 4, a control device 23 including a microcomputer and the like is provided in the machine room, and the front face of the main body 1 is used by the user to perform various cooking modes. An operation panel 24 for setting items such as the above is provided. The control device 23, based on the user's setting, a predetermined cooking program, and the detection of the weight sensor 20, etc., the magnetron 9, the heater 10, the fan device 11, the rotary shaft drive motor 17, the upper heater 12, the front side. The movable heater 13, the front heater motor 21, the rear movable heater 14, and the rear heater motor 22 are controlled.

At this time, as will be described in detail later in the description of the operation, the control device 23, when the grilled fish cooking is selected by the operation panel 23, detects the weight of the fish F based on the weight detection of the weight sensor 20. Is determined, and the two movable sensors 13 and 14 are selectively moved to the heating position in accordance with the number, and they are selectively energized.

Therefore, the front heater motor 21, the back heater motor 22, the control device 23 and the like constitute the heater moving means according to the present invention, and the control device 23 functions as a heater energizing means. It is like this.

Next, the operation of the above configuration will be described with reference to FIGS. 5 to 7 and 9. Now, when the user wants to cook grilled fish (for example, grilled saury with salt), first, the top plate 18 and the grill 19 are set on the rotating plate 16 in the cooking chamber 2, and the grill 19 is placed. The fish F is placed on the placing surface 19a.

At this time, for example, according to the instruction of the instruction manual, if the number of the fish F to be cooked is one, the user puts the fish F on the front side of the grill 19 as shown in FIG. Place it on 19c. When the number of fish F to be cooked is two, as shown in FIG. 6, the fish F are placed in the recesses 19c at the center and the back of the grill 19, respectively. The three recesses 19c are respectively placed.

After that, when the user operates the operation panel 24 to select automatic cooking of grilled fish, the control device 23 causes the cooking to be performed as follows.

First, the weight sensor 20 detects the weight of the fish F placed on the grill 19, and the control device 23 determines how many fish F are placed from the weight. This judgment is made based on, for example, a data table stored in advance as shown in FIG.

Then, the control device 23 energizes the upper heater 12 and controls the two movable heaters 13 and 14 as follows according to the number of fish F. That is, when cooking one fish F, as shown in FIG. 5, only the front movable heater 13 is rotated to the heating position and only the front movable heater 13 is energized. Thus, the fish F is heated from the upper surface side by the upper heater 12 and is heated from the lower surface side by the front movable heater 13 so that the upper and lower surfaces are simultaneously heated and cooked. At this time, since the front movable heater 13 is arranged in the immediate vicinity of the fish F, efficient heating is performed.

Further, when cooking two fish F, as shown in FIG. 6, only the back movable heater 14 is rotated to the heating position and energized. As a result, the upper and lower surfaces of the fish F can be efficiently heated at the same time. Furthermore, when cooking three fish F, as shown in FIG. 7, both movable heaters 13 and 14 are rotated and energized.

After that, when the weight detected by the weight sensor 20 decreases by 10 to 20%, it is determined that the fish F has been baked, and the energization of each heater is stopped to complete the cooking. Then, the movable heaters 13 and 14 are returned to the retracted position. Although detailed description is omitted, the movable heaters 13 and 14 are not used at the retracted position when performing range cooking or oven cooking.

According to the present embodiment as described above, unlike the conventional one in which the flat heater is provided at the bottom of the cooking chamber, the movable heaters 13 and 14 are arranged on the grill 19 in the immediate vicinity of the fish F. Able to perform efficient cooking. Moreover, since the movable heaters 13 and 14 are rotationally displaced to the heating position only when they are used and retracted to the retracted position when they are not used, they do not interfere with the execution of other cooking.

Then, the two movable heaters 13 and 14 are provided at the front side and the back side in the cooking chamber 2 with different heating outputs, so that the fish F stored in the cooking chamber 2 can be provided. Since the movable heaters 13 and 14 are selectively used according to the number of fish F, even when the number of fish F is different, cooking can be performed in a homogeneous baked state without uneven baking. It is also possible to save power when the number of fish F is small.

Further, particularly in the present embodiment, the number of fish F is automatically determined, and the displacement and energization of the movable heaters 13 and 14 are also automatically performed, which makes the operation troublesome for the user. It is possible to carry out the above-mentioned high-quality cooking without imposing the above.

FIGS. 10 and 11 show another embodiment of the present invention. The difference from the above embodiment is that it is necessary to determine how many fish F are placed on the grill 19. In addition, instead of the weight sensor 20, three sets of optical sensors 31 are provided.

The optical sensor 31 is composed of, for example, a light projecting portion 32 provided on the side wall portion 3 of the cooking chamber 2 and a light receiving portion 33 provided on the opposite side wall portion 4 of the cooking chamber 2. Three sets are provided so as to correspond to the three recesses 19c of the grill 19, and the light from the light projecting portion 32 passes just above the recesses 19c.

Therefore, when the fish F is placed in the recess 19c, the position of the fish F placed on the basis of the fact that the light from the light projecting unit 32 is blocked by the fish F and is not received. Therefore, the automatic cooking of grilled fish can be performed as in the above-described embodiment.

According to such a configuration, the same effect as that of the above-described embodiment can be obtained, and, of course, the optical sensor 31 directly detects how many fish F are placed. Therefore, the weight sensor It is possible to detect the number of fish F more reliably than when using 20, and it is also possible to inform the user when the position where the fish F is placed is incorrect. It will be.

In each of the above-described embodiments, the movable heaters 13 and 14 are automatically displaced and energized. However, for example, the user can manually selectively displace the movable heater, or manually. Even if the movable heater to be energized is selected, the intended purpose can be achieved.

In addition, for example, a configuration may be adopted in which three or more movable heaters are provided, and the present invention is not limited to the open grill range and can be applied to all heating cookers using heaters. It can be implemented by appropriately changing it within the range.
