Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a heating cooker such as an electric oven having a mechanism for turning over an object to be heated such as fish.

[0002]

[Prior art]

 Various efforts have been made to ensure that foods such as fish can be baked well without being turned over during heating with a heating cooker such as an electric oven. In many cases, strong heaters were installed on the ceiling and bottom of the heating chamber.However, some food items were installed close to the ceiling heater, and the bottom of the heating chamber was installed. -Move the heater closer to the bottom of the food to improve the heating efficiency, circulate hot air in the heating chamber, and prevent the front and back of the food from including the part where the radiant heat of the heater is hard to reach. For example, something that can be baked uniformly has been used. In addition, a device that has both of the functions described above and is devised to enhance the heating performance on both the front and back surfaces has also been used.

[0003]

[Problems to be solved by the device]

 However, according to the conventional heating method described above, it was quite difficult to bake the food on the same side without turning it over, and the effect of the difference in the heating method appeared on the baking method. For example, a structure in which a heater is placed under the food is effective in reducing the time required for heating, but it is difficult to always bake the front and back regardless of the size and shape of the food. there were. In addition, there was a case where smoke was intensified due to the lower heater. On the other hand, in the case of using hot air, there is an effect that the burning of the front and back is relatively uniform, but it is not possible to expect the effect of burning due to the radiant heat of high heat, and it takes a lot of time to heat. There was a problem.

[0004]

[Means for Solving the Problems]

 The present invention incorporates a mechanism for rotating a grill installed in a heating chamber, having a portion that maintains a generally horizontal posture in a normal state and a portion that maintains a generally vertical posture. The food is placed on the upper part of the horizontal position of the rotating mechanism, first the heating and cooking of the upper side of the food is started, and then the rotating mechanism is rotationally driven by the driving device attached to the main body of the cooker at an appropriate time. This lifts the food, turning it 180 degrees in the vertical plane and turning it over. In the present invention, the horizontal position portion is kept out of contact with food during the heating before turning over.

[0005]

[Action]

 The food placed on the upper part of the horizontal position of the rotating mechanism of the grill which rotates from the horizontal position to the vertical position is first heated by the heater provided on the ceiling. Since the horizontal position of the rotating mechanism does not come into contact with food during that time, even if the food sticks to the grill during heating, it does not stick to the horizontal position of the rotating mechanism. Therefore, when the food is rotated by driving the rotation mechanism after that, the food tries to move downward due to its own weight, but the food contacts the part that was in the vertical posture in normal times and holds it without moving further downward. While advancing, the food advances further and eventually the food is easily separated from the rotating mechanism to complete the inside out. From this point on, the food is placed in a different position than before. Then, the newly upper surface is heated.

【Example】

 A description will be given below with reference to the embodiment drawings. FIG. 1 shows a cross section of the electric oven as seen from the lateral direction, with a part of the cross section omitted. In FIG. 1, reference numeral 1 is a heating chamber for an electric oven, 2 is a heating chamber case for forming the heating chamber 1 inside the oven, and 3 is a door for opening and closing an inlet opening of the heating chamber 1. Is. 4 and 5 are heaters installed on the ceiling of the heating chamber, 6 is a grill, 7 is a driving device, 8 is a driving motor of this driving device, and 9 is a heater, a driving device and It is a control circuit for driving and controlling the driving motor.

FIG. 2 shows the relationship between the grill 6 and the drive unit 7. Reference numeral 10 denotes a grill outer frame, which is supported by racks 12 and 12 provided on a heating chamber side wall 11. A plurality of corrugated wires 13a, 13b, ... Are attached to the grill net outer frame 10 as shown in the figure, and support a saury (swordfish) 14 which is an object to be heated. Since FIG. 2 takes a saury as an example of an object to be heated, it is symbolically drawn so that the saury should be supported without any problem. Therefore, other members such as the corrugated wires 13a, 13b, ... Should be appropriately installed and deployed as necessary and within a range that does not hinder the operation of the inside-out mechanism of the object to be heated, which will be described later.

Reference numerals 15a and 15b denote rotation shafts, which are rotatably supported by rotation shaft support plates 16a and 16b attached to both sides of the grill outer frame 10. Cranks 17a and 17b are formed on one side of the rotary shafts 15a and 15b, that is, on the right rotary shaft support plate 16b side of FIG.

Reference numeral 18 is a slide plate, and the cranks 17 a and 17 b are connected to vertically long connecting holes 19 a and 19 b formed in the slide plate 18. Further, the slide plate 18 is attached to the rotary shaft support plate 16b by a slide guide formed by cutting and raising the rotary shaft support plate 16b as shown by reference numerals 20a and 20b in the longitudinal direction of the heating chamber. There is.

Reference numerals 21a and 21b are guide slits formed in the slide plate 18 and inserted through the slide guides 20a and 20b to determine the slide direction and the slide amount of the slide plate 18. Further, an engaging hole 22 is opened at the end of the slide plate 18 on the rear wall side of the heating chamber, and is detachably connected to the drive projection 23 of the drive device 7 described at the beginning of this embodiment. ing. The other end of the drive projection 23 projects outside the heating chamber 1 and is connected to the driving motor 8 via a connecting mechanism 24.

The rotary shaft 15b, which is driven by the drive protrusion 23 and is driven to rotate by the slide plate 18 that slides, is configured to rotate about 100 degrees in this embodiment. The rotation angle was set to about 100 degrees because it is thought that if the rotation angle exceeds 100 degrees and it rotates about 100 degrees, the food on the rotating inside out shelf will surely come off and the food can be turned inside out without failure. Is.

Next, 25 is attached to the rotary shafts 15a and 15b on one side and is kept in a horizontal posture in a normal state, and is rotated from the position of arrow A in FIG. 1 to the position of arrow B as the rotary shaft rotates. It is a rotating inside out shelf that changes the position by turning. 1 and 2 both show the state before or after the heating is started and before the rotating operation for turning over is performed.

When the driving motor 23 is actuated and the drive projection 23 slides inward of the heating chamber, the rotary inside-out rack 25 is interlocked and rotationally moved from the position indicated by arrow A to the position indicated by arrow B in FIG. The saury 14, which is the food to be heated, is rotated 180 degrees from the position drawn by the solid line on the right side of the figure to the position drawn by the dotted line on the left side, that is, turned over to change the position. Further, as shown in FIG. 1, the rotating inside-out shelf 25 is positioned at a position lower than the wavy wire 13, ... Care is taken not to contact the object to be heated 14. This is because the food often sticks to this rotating inside out shelf when it is touched during heating, making it difficult to remove the food from this shelf during the inside out operation. Is.

Reference numeral 26 denotes a part of the rotating inside-out shelf 25, which is attached to the rotating shafts 15a and 15b similarly to the rotating inside-out shelf 25, stands vertically in a normal state, and rotates while supporting the lower part of the food when rotating inside out. This is an inside-out facilitator that promotes reliable turning of the food.

One embodiment of the present invention is configured as described above, and the cooking is started after the saury 14 is installed at the upper position of the rotating inside out shelf 25 as shown in FIG. Then, the heating chamber door 3 is closed and other necessary operations are performed to start heating. At this time, the state in which the saury 14 and the rotating inside out shelf 25 are not in contact with each other is maintained.

When the surface of the sammer 14 on the side of the heater 5 is burned by the radiant heat of the heater 5, the necessary operation is performed again, and then the driving motor 8 is operated. Then, the slide plate 18 moves to the right in FIG. 1 by the drive protrusion 23. In conjunction with this, the turning inside-out rack 25 starts to rotate counterclockwise, contacts the saury 14 at a slightly advanced angle, and increases the turning angle while lifting the saury. On the way, the saury touches the inside-out accelerating portion 26 below by its own weight and further advances while being held without moving further downward. At this point, the saury 14 is in contact with the rotating inside out shelf 25, but they do not stick together. Finally, the turning inside out shelf 25 reaches the position of the arrow B in FIG.

Usually, before this state is reached, the saury has already begun to be detached from the rotary inside-out shelf 25, turned over by being turned over by 180 degrees as shown in FIG. 1, and placed in a new position. After that, the surface that was not exposed to the radiant heat of the heater faces the heaters 4 and 5, and the baking is started. The rotating inside-out shelf 25 rotates about 100 degrees to turn over the saury, and then keeps the posture as it is until the end of cooking. Then, the heating ends when it is baked.

[0018]

[Effect of device]

 As described above, according to the present invention, the object to be heated can be reliably rotated and turned over by the mechanical device. As a result, we were able to realize automation and labor saving of cooking that requires inside-out work such as fish grilling. Moreover, since the work proceeds without opening the door, the hot air in the heating chamber does not escape and energy saving was achieved. Furthermore, since the object to be heated is heated under the heater, we succeeded in minimizing smoke generation during heating.
