The heating cooker according to the fourth embodiment of the present invention will be described in detail below. In addition, common reference numerals are given to portions common to the heating cooker of the first to third embodiments described above, and descriptions of common portions are omitted as much as possible to avoid duplication.

FIG. 16 schematically shows the configuration inside the conventional cooking chamber 3. As shown in FIG. In the figure, 51 is a two-tier plate fixing portion projecting from the left and right side walls of the cooking chamber 3 , and 52 is an upper and lower heater mounting portion for mounting a heater 53 in the internal space of the main body 1 . The plate fixing portion 51 is for placing a bottomed plate as an accessory (not shown). 51, and radiant heat mainly from a heater 53 disposed on the upper side of the cooking chamber 3 is used to oven-heat the food.

In the conventional heating cooker, the plate is fixed at the position where it is placed on the plate fixing portion 51 inside the cooking chamber 3, so if there is a certain distance between the heater and the food to be cooked, cooking is difficult. It was taking time. In addition, there are foods to be cooked that swell upwards as they are heated. Furthermore, it was almost impossible to cook food on a plate by roasting it. This embodiment solves these problems and proposes an oven range as a heating cooker that can make maximum use of heater heat in cooking with a heater.

FIG. 17 schematically shows the configuration inside the cooking chamber 3 in the microwave oven of this embodiment. In the same figure, instead of the above-described plate fixing portion 51, a vertically movable movable fixing device 55 is arranged along the left and right side walls inside the cooking chamber 3. As shown in FIG. The movable fixture 55 is provided so that a plate 58 (or a net), which is an accessory described later, can be fixed at at least two locations. It is configured. Reference numeral 56 denotes sensors for preventing excessive rise, which are arranged on the upper left and right side walls inside the cooking chamber 3, respectively. Here, too, the heaters 53 are positioned above and below the cooking chamber 3 and are provided in the internal space of the main body 1 using the heater mounting portions 52. 3 may be provided only on the upper side.

FIG. 18 shows the state of the cooking chamber 3 shown in FIG. 17 during cooking. During cooking, one or more objects to be cooked F are placed on a plate 58 with a bottom, and the plate 58 is placed in the cooking chamber 3 and fixed to the movable fixture 55 . Depending on the food F to be cooked, a net may be used instead of the plate 58 .

In addition, since the appearance configuration of the microwave oven in this embodiment is the same as that of the heating cooker in the second embodiment, description and illustration thereof will be omitted.

FIG. 19 shows the electrical configuration of the main body 1 related to the characterizing portion of this embodiment. The microwave oven of this embodiment includes an excessive rise detection means 61 including the above-described excessive rise prevention sensor 56 and a movable fixator moving means 62 for moving the movable fixator 55 up and down. A computer 15 is additionally electrically connected. Further, the microcomputer 15 receives operation signals from the item selection means 12 and the item determination means 13 and detection signals from the excessive rise detection means 61, and controls the movement of the movable fixator movement means 62. means, and these points are different from the microwave ovens of the first to third embodiments.

Although part of the configuration is omitted in FIG. 19, the microwave oven of this embodiment has the same electrical configuration as that of the first embodiment described above. The heater 53 described above corresponds to the heater heating means 32 shown in FIG.

FIG. 20 shows a circuit example of the excessive rise detection means 61. As shown in FIG. In the figure, the excessive rise prevention sensor 56 is composed of a non-contact infrared sensor consisting of an infrared LED 56A that is a light emitting element and a phototransistor 56B that is a light receiving element. An operating voltage Vcc is applied. The infrared LED 56A is connected in series with a transistor 71 serving as a switch element, and the phototransistor 56B is connected in series with a resistor 72. FIG. 74 is a resistor for limiting the base current of the transistor 71, and 75 is a resistor for preventing malfunction of the transistor 71. FIG.

The base of transistor 71 is connected to the output port of microcomputer 15 via input resistor 74 , and the connection point between phototransistor 56 B and resistor 72 is connected to the input port of microcomputer 15 . As a result, in order to automatically adjust the position of the movable fixture 55, an automatic position adjustment signal, which is an H (high) level control signal, is output from the fixture operation control means 38 to the base of the transistor 71. Then, the emitter-collector of the transistor 71 is turned on, current flows through the infrared LED 56A, and infrared rays are emitted, and the excessive rise detection means 61 becomes effective. At this time, the excessive rise prevention sensor 56 detects the position (height) of the food F placed on the plate 58 in the cooking chamber 3, and detects the position (height) of the food F placed on the dish 58 in the cooking chamber 3, and reaches the position where the phototransistor 56B receives the infrared rays from the infrared LED 56A. When the object F to be cooked rises and an excessive rise of the object F to be cooked is detected, the phototransistor 56B is turned on, and the connection point between the phototransistor 56B and the resistor 72 is directed to the fixing device operation control means 38. It is configured such that an H-level excessive rise detection signal is input.

FIG. 21 is a waveform diagram of each part when the excessive rise detection means 61 of FIG. 20 is used. 15 output port 15 to movable fixator moving means 62, showing a lowering instruction signal associated with over-up detection.

The movable fixture moving means 62 includes, for example, a forward/reverse rotatable motor that serves as an electric drive source, a drive transmission mechanism that converts the rotational motion of the motor into linear motion of the movable fixture 55, and transmits the motion. A position detection mechanism detects the position of the movable fixture 53 and sends a detection signal to the microcomputer 15 . As described above, the H-level automatic position adjustment signal is output from the fixator operation control means 38 to the excessive rise detection means 61, and in a state in which the excessive rise prevention detection of the excessive rise detection means 61 is enabled, the excessive rise is detected. When the means 61 detects an excessive rise of the food F to be cooked, an H-level excessive rise detection signal is sent to the fixing device operation control means 38 . In response to this, the fixture operation control means 38 moves down the food F placed on the plate 58 in the cooking chamber 3 and thus the movable fixture 55. It is configured to send an L (low) level pulse-like descent instruction signal toward the moving means 62 .

Also, although not shown, to raise the movable fixture 55, another pulse-like rise instruction signal is sent to the movable fixture moving means 62 so as to reverse the rotation of the motor to that during the descent. As a result, the object to be cooked F placed on the plate 58 and the movable fixture 55 can be not only lowered stepwise but also raised stepwise.

Note that the circuit diagram shown in FIG. 20 is merely an example, and another configuration may be used as long as the same function can be achieved. Also, the level of each signal is not limited to the above example. For example, when the food F to be cooked is detected to have risen excessively, the phototransistor 56B is turned off instead of being turned on, and the excessive rise prevention sensor 56 generates an excessive rise detection signal of L level instead of H level. may be selected. The movable fixture moving means 62 can also be configured using various driving sources other than the step motor as in the present embodiment, as long as the movable fixture 55 can be raised and lowered.

Next, the operation of the microwave oven of this embodiment having the above configuration will be described in detail with reference to the flow charts of FIGS. 22 and 23. FIG. These flowcharts all assume that the dish 58 on which the food F to be cooked is placed is fixed to the movable fixture 55 within the cooking chamber 3 .

FIG. 22 shows a procedure for setting the position adjustment of the food F to be cooked before starting cooking. Before cooking, the main body 1 is on standby as described above. 12 and the item determination means 13 are operated to determine whether or not the function for adjusting the position of the food F to be cooked has been selected (step S21).

In step S21, if the cooking start instruction means 9 is pressed without selecting the position adjustment function of the food F to be cooked, the process proceeds to step S28, where the movable fixture 55 and thus the food F to be cooked are placed. With the plate 58 fixed at that position, the cooking heating of the food F is started.

On the other hand, in step S21, when the position adjustment function of the food F to be cooked is selected, the process proceeds to the next step S22, and it is determined whether the selection is automatic or manual. It is determined by the control means 38 . In step S22, when the automatic position adjustment function is selected by operating the item selection means 12 and the item determination means 13, the process proceeds to a series of steps Sa consisting of steps S23 to S25, and the food to be cooked is To automatically adjust the position of F.

In step group Sa, the fixing device operation control means 38 determines whether or not the excessive rise prevention sensor 56 has detected excessive rise and sent an excessive rise detection signal to the microcomputer 15 (step S23). In step S23, if the excessive rise prevention sensor 56 does not send an excessive rise detection signal and does not detect an excessive rise of the food F to be cooked, an upward instruction signal for raising the movable fixture 55 is sent to the movable fixture moving means. 62, and the food F placed on the plate 58 (or net) is brought closer to the upper heater 53 of the cooking chamber 3 (step S24). On the other hand, in step S23, when the excessive rise prevention sensor 56 sends out an excessive rise detection signal and detects that the food to be cooked F has risen excessively, a lowering instruction signal for lowering the movable fixture 55 is sent to the movable fixture. The object to be cooked F placed on the plate 58 is separated from the upper heater 53 of the cooking chamber 3 by one step (step S25).

In this way, when the food F to be cooked is automatically adjusted to the optimum position in each procedure of the step group Sa, the movable fixture 55 stops at that position. Then, the process proceeds to step S26, where the food F to be cooked is started to be heated while the movable fixture 55 and the plate 58 on which the food F is placed are fixed at that position.

That is, if the user selects automatic position adjustment by appropriately operating the item selection means 12 and the item determination means 13 before cooking by heating with the heater, the movable fixture 55 is displayed before the start of cooking. The object to be cooked F placed on the plate 58 fixed to the plate 58 can be automatically brought closer to a position where it is not detected by the excessive rise prevention sensor 56 and can receive the heat of the heater 53 effectively.

On the other hand, in step S22 described above, when the manual position adjustment function is selected by operating the item selection means 12 and the item determination means 13, the process proceeds to a series of steps Sb consisting of steps S27 and S28. , the position of the food F to be cooked can be manually adjusted.

In step group Sb, the fixture operation control means 38 allows the user to turn the dial of the item selection means 12 in one direction so that the food F placed on the plate 58 can be manually moved before cooking is started. When it is rotated clockwise, an operation signal is received therefrom, and a lift instruction signal for lifting the movable fixture 55 is sent to the movable fixture moving means 62, and the user presses the dial of the item selection means 12. is rotated counterclockwise, which is the other direction, an operation signal is received therefrom, and a lowering instruction signal for lowering the movable fixture 55 is sent to the movable fixture moving means 62 . Also, by pressing a key that serves as the item determination means 13 , a stop instruction signal for fixing the movable fixator 55 at that position is sent to the movable fixator moving means 62 .

That is, when the user selects manual position adjustment by appropriately operating the item selection means 12 and the item determination means 13 before cooking by heater heating, the movable fixture 55 is moved to the position adjusted by the user. The food to be cooked F placed on the fixed plate 58 can be fixed.

Next, the operation after the start of heat cooking in step S26 will be described. When the heating control means 35 starts cooking the food F, the fixing device operation control means 38 shifts to step group Sc, and whether the excessive rise prevention sensor 56 has sent an excessive rise detection signal to the microcomputer 15 or not. It is determined whether or not (step S29). In step S29, if the shape of the object F to be detected does not change during cooking heating, the excessive rise prevention sensor 56 does not send an excessive rise detection signal, and the determination of step S29 is continued. changes and swells upward during cooking and heating, and when the excessive rise prevention sensor 56 detects this and sends out an excessive rise detection signal, a lowering instruction signal for lowering the movable fixture 55 is sent to the movable fixture movement. The food F placed on the plate 58 is separated from the upper heater 53 of the cooking chamber 3 by one step (step S30).

That is, if the user selects automatic position adjustment by appropriately operating the item selection means 12 and the item determination means 13 before cooking by heater heating, the food F to be cooked rises upward during cooking. When the excessive rise prevention sensor 56 detects the bulge, the food F placed on the plate 58 fixed to the movable fixture 55 can be automatically moved away from the upper heater 53 of the cooking chamber 3. be possible.

Next, based on the flowchart of FIG. 23, the procedure for setting the position adjustment of the food F to be cooked will be described. While the heating control means 35 controls the heater 53 to heat the food F placed on the plate 58 fixed to the movable fixture 55, the fixing device operation control means 38 controls the item selection means 12 and the item determination means 13 to determine whether or not the position adjustment function of the food F to be cooked has been selected (step S31).

In step S21, if the position adjustment function for the food F to be cooked is not selected, the process proceeds to step S37, where the position adjustment during heat cooking is not performed, and the movable fixture 55 and thus the food F to be cooked are finished. The cooking heating of the food F to be cooked is continued while the plate 58 placed thereon is fixed at that position.

On the other hand, in step S31, when the position adjustment function of the food F to be cooked is selected, the process proceeds to the next step S32, and it is determined whether the selection is automatic or manual. It is determined by the control means 38 . In step S32, when the automatic position adjustment function is selected by operating the item selection means 12 and the item determination means 13, the process proceeds to a series of steps Sd consisting of steps S33 to S35 to To automatically adjust the position of F.

In step group Sd, the fixator operation control means 38 takes in the detection signal from the position detection mechanism incorporated in the movable fixator moving means 62 and stores the current position of the movable fixator 55 in the memory means. With this as the original position of the movable fixture 55 and the food F to be cooked, the food F placed on the plate 58 fixed to the movable fixture 55 is automatically moved to the lowest position. Then, a lowering instruction signal is sent from the fixator operation control means 38 to the movable fixator moving means 62 (step S33). Thereby, the user can confirm the finish of the food F in the cooking chamber 3 through the transparent window portion of the door 4 with the door 4 closed.

Thereafter, the fixing device operation control means 38 proceeds to step S34, and determines whether or not the item selection means 12 and the item determination means 13 have been operated to return the food to be cooked F to its original state. In step S34, if the item to be cooked F is selected to be returned to its original position, the process proceeds to step S35, in which a raise instruction signal is sent from the fixator operation control means 38 to the movable fixator moving means 62 to automatically The movable fixture 55 is returned to the original position stored in the storage means. Then, the process proceeds to step S37, the position adjustment during heat cooking by the fixing device operation control means 38 is completed, and the food F to be cooked is heat-cooked at the original position. On the other hand, in step S34, if the item to be cooked F is not selected to be returned to its original state, the process proceeds to step S37, where the position adjustment during heat cooking by the fixing device operation control means 38 is completed, and the item to be cooked F is cooked at the lowest position.

In this way, after moving the object F to be cooked to the lowest position in the cooking chamber 3 and visually recognizing the finish of the object F to be cooked through the door 4, the object to be cooked F is returned to its original position to continue the heat cooking. , or to keep the food F to be cooked at the farthest position from the heater 53 to continue cooking, at the user's will.

On the other hand, if the manual position adjustment function is selected by operating the item selection means 12 and the item determination means 13 in step S32, the process proceeds to step S36, and the position of the food F to be cooked is manually adjusted. so that it can be adjusted with As described above, when the user rotates the dial of the item selection means 12 in one direction, clockwise, an upward instruction signal for raising the movable fixator 55 is sent to the movable fixator moving means 62 . When the user rotates the dial of the item selection means 12 counterclockwise in the other direction, a lowering instruction signal for lowering the movable fixture 55 is sent to the movable fixture moving means 62 . Also, by pressing a key that serves as the item determination means 13 , a stop instruction signal for fixing the movable fixator 55 at that position is sent to the movable fixator moving means 62 .

As a result, even during cooking by the heater 53, if the item selection means 12 and the item determination means 13 are appropriately operated to select manual position adjustment, the position adjusted by the user is fixed to the movable fixture 55. The food F to be cooked on the plate 58 can be fixed.

Further, in the microwave oven of the present embodiment, the cooking menu information storage means 16 contains all the information of the roasting menu that enables roasting cooking as the cooking menu by heating the food F to be cooked by the heater. When a roasting menu is selected from among a plurality of cooking menus by operating the item selection means 12 and the item determination means 13, the fixture operation control means 38 cooperating with the heating control means 35 activates the movable fixture 55. The object to be cooked F placed on a plate (or net) 58 fixed to the plate is automatically brought close to a position where it is not detected by the excessive rise prevention sensor 56 and can receive the heat of the heater 53 effectively. At least while the heating control means 35 controls the heater 53 arranged above the cooking chamber 3 to heat the food F to be cooked by the heater, the movable fixture 55 is controlled by the fixture operation control means 38. are individually moved to incline the plate 58 in various directions, so that the food F placed on the plate 58 is evenly roasted, which is almost impossible with a conventional heating cooker. Uniform roasting of the food F to be cooked can be realized.

As described above, in the microwave oven as a cooking device according to the present embodiment, as shown in step group Sa in FIG. When the automatic position adjustment function is selected by the means 13, the food F placed on the plate (or net) 58 fixed to the movable fixture 55 is automatically prevented from rising excessively before cooking is started. A fixator operation control means 38 is provided as control means for adjusting the position of the movable fixator 55 so that it is not detected by the sensor 56 and is as close as possible to the position of the heater 53 serving as the heating means.

In this case, the excessive rise prevention sensor 56 automatically moves the food F to a position where it is most likely to receive heat from the heater 53, thereby shortening the cooking time for the food F to be cooked. In addition, in the case of using a heating cooker having heaters 53 on the upper and lower sides of the cooking chamber 3 to brown both sides of the food to be cooked F, the heaters 53 are automatically brought closer to the upper and lower heaters 53 . , it is possible to finish the food F to the selected browning color.

Further, in this embodiment, as shown in the step group Sb of FIG. 22, the user selects the manual position adjustment function by the item selection means 12 and the item determination means 13 before the user starts cooking by heating with the heater. Then, before the start of cooking, the food F placed on the plate 58 fixed to the movable fixture 55 is raised by rotating the item selection means 12, which also serves as the position adjustment instruction means, in one direction. A fixator operation control means 38 is provided as control means for adjusting the position of the movable fixator 55 so as to lower it by rotating the item selection means 12 in the other direction.

In this case, regardless of detection by the excessive rise prevention sensor 56, the position of the food F to be cooked in the cooking chamber 3 can be manually set at the user's will. Further, by manually moving the food F to a position where the heat of the heater 53 is likely to be received, the cooking time for the food F can be shortened.

Further, in this embodiment, as shown in the step group Sc in FIG. 22, the user selects the automatic position adjustment function by the item selecting means 12 and the item deciding means 13 before the user starts cooking by heating with the heater. Then, when the object to be cooked F swells upward during cooking and the excessive rise prevention sensor 56 detects the bulge, the object to be cooked F placed on the plate 58 fixed to the movable fixture 55 is automatically moved. Specifically, it is provided with fixator operation control means 38 as control means for adjusting the position of the movable fixator 55 so as to keep it away from the heater 53 serving as the heating means.

In this case, when the excessive rise prevention sensor 56 detects that the food F has swelled upward during cooking, the food F is automatically moved to a position where it is not detected by the excessive rise prevention sensor 56. can be kept away from the heater 53 immediately. Further, even when the food F to be cooked is in a swollen state, the cooking time for the food F to be cooked can be shortened by moving to a position where the heat of the heater 53 is most likely to be received according to the state.

In this embodiment, as shown in the step group Sd of FIG. 23, in order for the user to check the finish of the food F to be cooked during cooking by heating with the heater, the item selection means 12 and the item determination means are selected. 13 selects the automatic position adjustment function, the food F placed on the plate (or net) 58 fixed to the movable fixture 55 can be automatically moved to the lowest position in the cooking chamber 3. , the fixture operation control means 38 as a control means for adjusting the position of the movable fixture 55 is provided, and after confirming the finish of the food F to be cooked, the item selection means 12 and the item determination means 13 are operated. It is configured such that it is possible to select whether or not to return the object F to its original position.

In this case, the user can check the finish of the food F in the cooking chamber 3 with the door 4 closed. After visually confirming the finish of the food F, the food F is returned to its original position to continue cooking, or the food F is moved to the farthest position from the heater 53 to continue cooking. can be selected.

Further, in this embodiment, as shown in step S36 in FIG. 23, when the user selects the manual position adjustment function using the item selection means 12 and the item determination means 13 as selection means during cooking by heater heating, the heating Before cooking is started, the food F to be cooked placed on the plate 58 fixed to the movable fixture 55 is raised by rotating the item selection means 12, which also serves as the position adjustment instruction means, in one direction. 12 is rotated in the other direction to lower the movable fixture 55, and a fixture operation control means 38 is provided as a control means for adjusting the position of the movable fixture 55.
