[0002]

2. Description of the Related Art Conventionally, as a heating cooker of this type, as shown in a schematic configuration diagram of FIG. 16, a casing 1 forming an outer shell.
A cooking chamber 2 having an open front is provided therein, a magnetron 3 is provided at a side of the cooking chamber 2, and an electric heater 4 is provided at an upper ceiling portion. In addition, a rotary plate 5 for placing and rotating an object to be cooked is provided in the lower part of the cooking chamber 2, a removable square plate 6 is provided in an intermediate portion, and an opening on the front surface can be opened and closed. A door 7 is provided.

However, one heating cooker can perform various kinds of cooking, for example, microwave heating is suitable for warming cooking and cooking of root vegetables, and the rotary plate 5 is provided with an object to be cooked. Are placed and housed, and the magnetron 3 is energized and driven to perform microwave heating. On the other hand, heater heating is suitable for grilling toast, gratin, etc.
The electric heater 4 is energized to generate heat in a state in which the food to be cooked is placed and accommodated by means of the above. Further, in the chawanmushi cooking and the sponge cake cooking, the microwave heating and the heater heating are selectively used sequentially so that the heating cooking by different heating sources can be appropriately performed.

[0004]

As described above, it is convenient because a large amount of cooking can be carried out by using different heating sources, but especially in the case of heating with the electric heater 4, a sufficient finish can be obtained depending on the cooking menu. In some cases, there was no case, and the degree of use of electric heaters tended to be less than that of microwave heating. That is, the cooking chamber 12
Is configured to be compatible with both microwave heating and heater heating.

In the heating with the heater, the heat energy from the electric heater 4 is consumed to heat the peripheral wall surface of the cooking chamber 2, or the large cooking chamber 2 is heated.
It took time to start cooking, because it took time to warm up.

[0005] In the case of bread such as toast cooking in which the food to be cooked is flat, one of the cooking chambers 2 is rather too wide and tends to be largely separated from the electric heater 4 which is a heating source. There is a problem that it takes a long time to cook and it is difficult to bake both sides evenly, and optimal cooking cannot be done depending on the cooking menu.

In order to deal with this, conventionally, it has been proposed to rotate and displace the heater itself so as to change the position of the electric heater. However, rotating the electric heater makes the electric contact structure movable. In addition, it requires a large space for rotation, and when a square plate or an object to be cooked is stored, it is an obstacle and cannot rotate. It is used as a room, and the heating efficiency is not always sufficient.

Among them, the upper heater 18 is provided on the ceiling of the cooking chamber 12, and the lower heater 19 is the upper and lower doors 15a,
The upper heater 18 and the lower heater 19, which are electric heaters, are provided transversely at the boundary portion between 15b so that they do not overlap when projected from above. Especially, in the vicinity of the lower heater 19, a rotatable partition plate 2 is provided.
0 is provided transversely, the partition plate 20 is composed of a plurality of plate-shaped pieces 20a to 20f, the details of which will be described later, and by this rotational displacement, the cooking chamber 12 is vertically moved with the partition plate 20 as a boundary. The so-called cooking chamber 12 can be constituted as a substantially original chamber, or can be divided into upper and lower parts so that it can communicate with and block from the direction.

In the present embodiment, as shown in FIG. 1, the upper door 15a is provided with a mesh tray 21 so as to interlock with its opening and closing.
Are connected to each other, that is, can be moved in and out of the upper opening 13a in the front-rear direction, and are slidably provided via a guide rail (not shown) formed on the inner side surface of the cooking chamber 12. The mesh tray 21 has a mesh shape in which a plurality of metal wire rods are arranged in parallel along the rod-shaped extending direction of the upper and lower heaters 18 and 19 as shown in FIG. 4, which will be described later. Further, in the lower section of the cooking chamber 12 corresponding to the lower door 15b and the lower opening 13b, a enamel-treated square plate 22 (shown by a chain double-dashed line) used during heater cooking is detachably accommodated, and is illustrated. However, as is well known, it is adapted to be selectively placed and supported on a step portion projecting from the inner surface of the cooking chamber 12 and at two height positions in the vertical direction.

An operation panel 23 is provided on the right front side of the front plate 14, which is a side of the doors 15a and 15b, for selecting and setting various cooking menus, setting cooking time, and displaying. In addition, a machine room 24 is formed between the outer peripheral wall surface of the cooking chamber 12 excluding the front side and the housing 11, and in a wide space portion of the machine room 24, particularly on the back side of the operation panel 23 (see FIG. 3). In addition to the magnetron 25 that oscillates microwaves, which is one of the heat sources as various electric components, a control device including a well-known cooling fan, a high-frequency transformer, a circuit board, etc. (not shown) A movable mechanism portion 26 (which will be described in detail later) for dynamically displacing is provided.

The specific constructions of the partition plate 20 and the movable mechanism portion 26 will be described with reference to FIGS. 4 to 7. First, FIG. 4 shows the upper and lower doors 15a and 15b.
2 is a perspective view of the cooking chamber 12 in a disassembled state, and in particular, schematically shows the arrangement configuration of the movable mechanism portion 26 of the partition plate 20.
Are provided on both the left and right sides (only the right side is shown) of the cooking chamber 12 from both outer side surfaces to the back side.

As shown in the enlarged perspective view of the main part of FIG. 5 (only one is disclosed), the movable mechanism portion 26 is, for example, a drive motor 27 composed of a geared motor, a drive gear 28 provided on its drive shaft, A transmission member 29 having a so-called rack function that meshes with the drive gear 28 and converts it into a linear motion is provided, and the partition plate 20 is linked to the transmission member 29 so as to be rotationally displaced. .

The specific structure of the transmission member 29 will be described with reference to an enlarged side view of the main portion of FIG. 7 in a cutaway manner. The transmission member 29 has a substantially rectangular plate shape and a rear end portion (shown in the figure). A guide member having a rack portion 29a that meshes with the drive gear 28 on the right side) and a long hole 29b provided in the horizontal direction at the substantially central portion, the peripheral portion of which is fixed to the outer wall of the cooking chamber 12. It is supported by 30, and is linearly slidable in the front-back direction, so that it can be reciprocated in the so-called arrow A and B directions in FIG. The front end side of the guide member 30 is formed in a bag shape to accommodate the end portion of the transmission member 29 (see FIG. 4).
Also, the elongated hole 29b serves as an escape groove of the terminal portion of the lower heater 19 when the transmission member 29 slides.

The partition plate 20 is provided in the cooking chamber 12 corresponding to the transmission member 29. That is,
The partition plate 20 includes a plurality of plate-shaped pieces 20 each having a rectangular shape.
a to 20f, and in particular, in the present embodiment, it is formed from a glittering aluminum material, stainless steel or a metal member whose surface is brightly treated so as to exert a function of a reflector. Then, it is rotatably attached to the side wall of the cooking chamber 12 through the support shaft pin 31 at substantially central positions of the left and right end faces in the respective longitudinal directions (see FIG. 6).

The support shaft pin 31 is arranged substantially concentrically with the lower heater 19 in the horizontal direction, and two plate-shaped pieces 20b and 20 are provided between the heater elements 19 except for both end portions.
c, and 20d and 20e are arranged respectively, and when they are rotated by a predetermined angle, one ends of adjacent ones are joined together, and one ends of the plate-like pieces 20a and 20f at both ends are the inner surface of the door and the inner surface of the cooking chamber 12 respectively. As an example of being joined to the above, and being cut off as a result, as shown in FIG. 1, a structure in which a mountain shape is formed which is uneven throughout.

As described above, when the cooking chamber 12 is vertically shut off by the partition plate 20, each heater element 19a of the lower heater 19 provided at substantially the same height position has the mountain shape of the partition plate 20. The cooking chamber 12 is arranged in a triangular recess, and one cooking chamber 12 is divided into two. In other words, in the state of being blocked from above and below, it is partitioned into an upper compartment 12a corresponding to the upper door 15a and a lower compartment 12b corresponding to the lower door 15b. In addition, when the partition plate 20 is rotated from this cutoff state and each of the plate-shaped pieces 20a to 20f is displaced in the vertical state, the upper and lower compartments 12a, 12 of the cooking chamber 12 are rotated.
Since b is in a communication state and can be formed and used as an original cooking chamber 12, the details of such rotation control of the partition plate 20 will be described later in the section for explaining the operation.

Thus, with respect to the plate-shaped pieces 20a to 20f rotatably supported by the support shaft pin 31, the movable pin 32 fixed to the transmission member 29 for simultaneously rotating them. Are connected. That is, since the movable pin 32 penetrates the side wall of the cooking chamber 12 and is connected to each of the plate-shaped pieces 20a to 20f, however, since the movable pin 32 slides together with the transmission member 29, it has a length corresponding to the stroke. The slit 33 is formed in the side wall. Then, the tip of the movable pin 32 which penetrates the slit 33 is inserted into the long groove 34 formed on both end surfaces (only the right side is shown) of the plate-shaped pieces 20a to 20f, and is slidable in the longitudinal direction and orthogonal ( It is connected in the engaged state in the (rotation) direction.

More specifically, since the movable pin 32 slides linearly as described above, the slit 33 of the cooking chamber 12 which allows the movable pin 32 to move may be linear. However, when the adjacent plate-shaped pieces 20c and 20d of the plate-shaped pieces 20a to 20f are described as an example,
As shown in FIG. 7, the plate-shaped pieces 20c and 20d are both vertical positions indicated by solid lines (left and right rotational positions (shown by reference symbols C1 and A1 and B1) displaced by a predetermined angle indicated by two-dot chain lines).
Since the pivot pin 31 is pivoted up to the center, the long groove 34 is set to have a length corresponding to the rotational displacement so that the movable pin 32 that moves linearly can slide in the long groove 34.

Therefore, for example, when the transmission member 29 is maximally moved in the direction of arrow A, the movable pin 32 which moves integrally moves through the slit 33 to the upper part of the plate-shaped piece 20c which is one end.
The movable pin 32 slides in the long groove 34 while pulling in the direction to displace the plate-shaped piece 20c to the rotating position A1. At the same time, the adjacent plate-shaped pieces 20d are rotated in the opposite direction, the lower side is pulled in the A direction and moved to the rotation position A1, and the lower ends of the plate-shaped pieces 20c and 20d are joined to each other to the upper part. Obtain an open (inverted) mountain-shaped form. On the contrary, when the transmission member 29 is moved to the maximum in the direction of the arrow B, the rotation pin 32 slides in the opposite direction to the above, and the plate-like pieces 20c and 20d are rotated to the opposite rotation position B1. Displace to.

As described above, the adjacent plate-shaped pieces 20a to 20a are rotated by rotating in different directions.
The lower end portion and the upper end portion of f are alternately joined to each other, so that the plate-shaped pieces 20a to 20f are connected in a mountain shape to substantially shut off the cooking chamber 12, and at the rotating position A1, the lower heater 19 is It is located in a mountain-shaped recess whose upper part is open, and the heat rays from the lower heater 19 are effective in the upward direction.
The slit 33 formed in the side wall of the cooking chamber 12 and in which the movable pin 32 moves is substantially closed by the transmission member 29 arranged along the outer surface thereof and the guide member 30 thereof.

The partition plate 20 is rotatably mounted and supported in the cooking chamber 12 via the support shaft pins 31 on both sides of the partition plate 20, that is, the plate-shaped pieces 20a to 20f are arranged side by side in the horizontal direction. At a predetermined rotation position A1 or B1 indicated by a chain double-dashed line in FIG. 7, the cooking chamber 12 is cut off transversely so as to eliminate a gap in the vertical direction, while the vertical position C1 shown by a solid line is the above. It is located in the middle of the rotation positions A1 and B1 and forms a state of communication in the vertical direction. However, at the predetermined turning positions A1 and B1 indicated by the two-dot chain line, the heater element 19a of the lower heater 19 arranged in each recess formed in a mountain shape is located at the opposite position where the partition plate 20 is turned upside down. Thus, the heating direction is selectively activated upward or downward through the partition plate 20.

Further, as shown in FIG. 7, a micro switch 35 which can be switched in three steps is provided so as to come into contact with and separate from the upper edge of the transmission member 29. For example, the transmission member 29 has a concave step 29c for pressing the push button 35a in three steps.
Is formed. The micro switch 35 operates in response to the sliding movement of the transmission member 29, and operates the transmission member 29.
By detecting the position in the stationary state, the rotation position of the partition plate 20 is detected, which functions as a so-called position sensor. The operation will be described later.

Next, the operation of the present embodiment configured as described above will be described with reference to the specific examples of heating by the heaters shown in FIGS. Incidentally, in these drawings, (a) of the drawings shows a configuration in which the partition plate 20 has different pivotal positions, and (b) of the drawings shows a specific heating action according to the pivotal position of the partition plate 20. It is a schematic structure figure for explaining based on a cooking example.

First, in FIG. 8A, the movable mechanism 26
In the form in which the transmission member 29 slides in the direction of arrow B and moves to the maximum with the driving of No. 3, each plate-shaped piece 20a to 20f is positioned at a predetermined rotation position B1 as shown in FIG. Then, the upper and lower parts of the cooking chamber 12 are shut off. Thus, in the shut-off mode by the partition plate 20, the lower heater 19 is located in a mountain-shaped recess whose upper side is open, the lower surface side of the so-called lower heater 19 is shut off, and the heat ray from the lower heater 19 is directed upward. Only in a valid state. Therefore, the heaters 18 and 19 at the upper and lower portions are heated in the facing direction as shown by the broken line arrows.

However, FIG. 2B shows an example of cooking suitable for heating the heater in the above-mentioned embodiment. For example, in order to carry out toast or grilled fish cooking in which double-sided grilling is effective for heating the object to be cooked from the front and back, the illustrated example is shown. Discloses toast cooking of two loaves of bread D as an object to be cooked. In order to start such cooking, the bread D is placed on the mesh tray 21 which is interlocked with the upper door 15a, and is prepared to be housed in the cooking chamber 12 through the upper opening 13a. When the toast cooking is selected and set by operating the cooking menu key, the movable mechanism section 26 is controlled by the control device (not shown).
Is controlled, and the partition plate 20 interlocks with the transmission member 29 to obtain the above-described cutoff state of FIG. 8, and the upper and lower heaters 18 and 19 as electric heaters are energized to generate heat and the bread B
Heat the heater from both the front and back.

In this case, for one large cooking chamber 12,
The upper compartment 12a, which is shut off by the partition plate 20, is partitioned and formed into a flat space which is surrounded by electric heaters from above and below and is effective for toast cooking, so that toast cooking can be efficiently performed. In addition, the partition plate 20 also has a heat ray reflection plate function,
Further, since it is possible to easily add a reflecting plate function to the ceiling portion of the upper heater 18, radiant heat can be effectively radiated toward the object to be cooked, and uniform and quick heating and cooking can be performed, so that the efficiency can be further improved. You can cook toast.

Next, referring to FIG. 9, the movable mechanism 26 is driven as shown in FIG. 9A, and the plate-shaped pieces 20a to 20 of the partition plate 20 are transmitted via the transmission member 29.
It shows a case where f is rotated to an intermediate vertical position (rotational position C1 shown in FIG. 7).
It is connected to the top and bottom without being cut off by, and is essentially the original one chamber.

However, FIG. 2 (b) shows the case where cooking of a large dish such as chicken E is performed as the food to be cooked, and the chicken E is placed on the square plate 22 from the lower opening 13b of the lower door 15b. At the same time, the upper and lower heaters 18 and 19 are used as an electric heater and are utilized as one cooking chamber 12.
Causes the plate-shaped pieces 20a to 20f in the parallel vertical state to be
Throughout the period, the chicken E is heated all at once from the upper side to the lower side, which enables cooking with a powerful heater.

FIG. 10 shows a case where so-called one-sided baking of an object to be cooked, such as gratin F or cookies, is performed, and the movable mechanism portion 26 is driven by the operation of the cooking menu key to be slid to the maximum in the arrow A direction. Transmission member 29
The partition plate 20 is rotationally displaced to the rotational position (the rotational position B1 shown in FIG. 7) that shuts off the cooking chamber 12 via the. To cut off the cooking chamber 12 and divide it into upper and lower parts is the same as in FIG.
However, the arrangement state of the lower heater 19 is different.

That is, when the transmission member 29 slides in the direction of arrow A, the plate-shaped pieces 20a to 20f rotate in the direction opposite to the case of FIG. 8, and the lower heater 19 forms a continuous mountain shape and is downward. Therefore, the heat rays of the lower heater 19 are effective only toward the lower side which is blocked by the partition plate 20. In this case, the plurality of gratins F are put into and taken out from the upper and lower doors 15a and 15b, respectively, and the gratins F are placed and housed on the mesh plate 19 in the upper compartment 12a of the cooking chamber 12 and the square plates in the lower compartment 12b. 22
Placed and housed using.

When the cooking is started according to the setting of the cooking menu as described above, the movable mechanism section 26 is drive-controlled by the control device (not shown), and the partition plate 20 is automatically rotated through the transmission member 29. It is controlled and displaced to a predetermined rotation position, and the heaters 18 and 19 at the upper and lower portions effectively heat and cook the gratin F contained in the compartments 12a and 12b. The stationary position of the partition plate 20 before cooking is at an appropriate rotation position according to the previous cooking menu.
The micro switch 35 as a position sensor is connected to the transmission member 2
Since the partition plate 20 is provided so as to be switched in three stages in accordance with the sliding movement, the partition plate 20 is based on the control device that inputs the result of detecting the current position, and the proper rotation position according to the cooking menu to be performed next. Is automatically rotated.

As described above, according to the above embodiment, the following effects can be obtained. That is, the door for opening and closing the front opening 13 of the cooking chamber 12 is configured to include at least two upper doors 15a and 15b in the vertical direction, and is provided on the ceiling of the cooking chamber 12 as an electric heater. It is composed of an upper heater 18 and a lower heater 19 provided across the boundary between the upper and lower doors 15a and 15b, and the cooking chamber 12 can be vertically communicated with and cut off in the vicinity of the lower heater 19. The partition plate 20 is provided.

Therefore, originally one cooking chamber 12 is divided into the partition plate 2
It can be divided into upper and lower parts by 0, and effective heating and cooking can be performed in each of the small compartments 12a and 12b, which enables efficient heating and cooking according to the cooking menu, and an effective cooking menu. Expected to increase. Of course, it is possible to provide a heating cooker that is practical and easy to use, for example, the food to be cooked can be easily taken in and out by the two doors 15a and 15b corresponding to the respective compartments 12a and 12b.

Moreover, the partition plate 20 is composed of a plurality of rotatable rectangular plate-shaped pieces 20a to 20f, and the cooking chamber 1 is rotated by the rotation of the plate-shaped pieces 20a to 20f.
2 can be connected and disconnected vertically. More specifically, at least the lower heater 19 is composed of a plurality of rod-shaped heater elements 19a, and the plate-shaped pieces 20a to 20f are rotatably provided at appropriate intervals between the heater elements 19a. , Especially when shutting down the cooking chamber 12 in the vertical direction, adjacent plate-shaped pieces 20a-2
One end of 0f is joined to form a mountain-like continuous shape to form upper and lower compartments 12a and 12b, and the heater element 19a is located in the mountain-shaped recess.

As a result, the plate-shaped pieces 20a, which can be miniaturized, are
Since it is sufficient to rotate 20f at a position sandwiching each heater element 19a, safety is improved without rotating the electric heater as in the conventional case, and a large rotation space is not required and the lower heater 19 and The partition plate 20 and the partition plate 20 can be configured compactly, which is effective for installation in the cooking chamber 12.

Further, since it is possible to select the heating that makes the lower heater 19 effective in the vertical direction, the upward direction, or the downward direction by controlling the rotation of the plate-shaped pieces 20a to 20f, the fixed lower heater 19 is fixed. In this embodiment, it is possible to use the heater for heating in at least three directions (a plurality of cooking menus),
It is also advantageous in that cooking can be efficiently performed by heating with a heater, and a cooking menu with a truly good finish can be secured and provided. Among them, when heating the cooking chamber 12 as a so-called one chamber that communicates with the upper and lower sides, the upper heater 18 and the lower heater 19 as electric heaters do not overlap each other when projected from above.
