Description

  The present invention relates to a drawer-type heating cooker provided with a rotary table mechanism for uniformly heating a heated object.

  A cooking device has been proposed in which a drawer unit integrated with an open / close door can be pulled out to the front side of the cooking device, but this type of drawer-type cooking device has a built-in installation under the counter top of the kitchen. Since the cooking device can be installed without occupying the countertop, it is suitable for a kitchen configuration in which a plurality of cooking devices are arranged in three dimensions, so it is positioned as one of the cooking devices that make up the system kitchen. Then, in recent years, the spread has expanded.

  As an example of a drawer-type microwave oven that is a drawer-type heating cooker, the present applicant moves within the cooker body so that the cooker body having a heating chamber and the cooking chamber body can be pulled out from the heating chamber A component having high heat resistance and flame retardancy by providing a drawer body that can be arranged and a slide rail for moving the drawer body inside the cooker body, and by providing the slide rail outside the heating chamber There has been proposed a drawer-type heating chamber cooker that does not require a slide mechanism made of materials and can prevent the occurrence of discharge failure due to microwaves (see Patent Document 1).

  The conventional drawer-type microwave oven described in Patent Document 1 has a slide mechanism for linearly moving the drawer body outside the heating chamber and on the side and bottom surfaces of the heating chamber. It is difficult to feed the microwaves from the side or bottom. Therefore, a top power feeding structure is employed in which a waveguide for guiding microwaves is installed on the ceiling of the main body, which is outside the heating chamber, and microwaves are supplied into the heating chamber.

  On the other hand, as a uniform heating mechanism for uniformly heating food such as food in a general microwave oven installed on the counter top of the kitchen, a rotary turntable is provided on the bottom of the heating chamber, and the heated object is mounted. In turntable-type microwave ovens that rotate the turntable during cooking and drawer-type microwave ovens where it is difficult to use a turntable, rotation of a non-uniform shape such as a metal plate in the microwave path on the ceiling A rotating stirrer or a rotating antenna type microwave oven has been proposed and mass-produced, in which a body is provided and the rotating body is rotated during cooking to stir the distribution of microwaves in the heating chamber.

  In a drawer-type microwave oven, if it is going to adopt a turntable method as a uniform heating mechanism, a rotary turntable will be arranged in the drawer, but a drive mechanism is provided in the linearly-movable drawer, Therefore, it is difficult to supply power, and it is difficult to dispose the turntable and its driving mechanism in a narrow space in the vertical direction. Therefore, as a uniform heating mechanism, a rotating antenna is incorporated in a waveguide provided on the top surface of the heating chamber, which is a fixed part. Since such a uniform heating mechanism is employed, it is necessary to employ a top surface feeding structure that supplies microwaves from the ceiling surface into the heating chamber.

  In a drawer-type microwave oven, for example, when a beverage is heated, the container containing the beverage is placed in a drawer that is put in and out of the heating chamber. However, the height of the container varies widely, and depending on the design designer, There are many cases that make a thin and tall container. To make it possible to store such a tall container in the heating chamber, the height of the heating chamber will be high, but if the top power feed structure is adopted, the ceiling height of the microwave oven will inevitably increase. I must.

As described above, in the drawer type microwave oven having the existing structure, a feeding structure such as a waveguide and a uniform heating mechanism such as a rotating antenna mechanism are provided in the ceiling portion, and a space for arranging them is required in the ceiling portion. However, the space in which the drawer type microwave oven is built-in is strictly limited in the height direction as the structure of the system kitchen, so it is practically impossible to increase the height of the drawer type microwave oven. It is. Thus, since the overall height of the microwave oven is limited, it has been difficult to meet the demand for the size (height) of the heated object.

  Therefore, in the drawer type heating cooker, instead of the top surface feeding structure and the uniform heating mechanism provided on the ceiling, the feeding structure and uniform heating mechanism are constructed by using the external space on the side and bottom of the heating chamber. There is a problem to be solved.

  An object of the present invention is to solve the above-mentioned problem, and eliminates the top surface feeding structure by a waveguide provided in the ceiling and a uniform heating mechanism such as a rotating antenna mechanism, and the entire heating cooker It is an object of the present invention to provide a drawer-type heating cooker that can increase the ceiling height of the heating chamber as much as possible without increasing the height.

  In order to solve the above-described problems and achieve the above object, a drawer-type heating cooker according to the present invention includes the drawer body that can be pulled out or stored from a cooker body in which a heating chamber is formed. An open / close door provided on the drawer body is a drawer-type heating cooker that closes the front opening of the heating chamber when the drawer body is housed, and a rotary table and a driving mechanism thereof are disposed on the bottom wall of the drawer body. A side feeding structure is arranged in a side space on the outside of the heating chamber.

  According to this drawer-type heating cooker, a side feeding structure is adopted as a feeding structure for supplying microwaves into the heating chamber, and a rotary table and its driving mechanism are disposed as a uniform heating mechanism with respect to the bottom wall of the drawer. Therefore, these power feeding structures and uniform heating mechanisms are not arranged on the ceiling. The waveguide that guides the microwave generated by the high-frequency generator that generates the microwave is disposed in the side surface space outside the heating chamber and has a side feeding structure, and the microwave propagated through the waveguide. Is irradiated into the heating chamber from the side wall of the heating chamber. Uneven heating of the heated product that occurs at that time is prevented by the rotating table rotating in the heating chamber.

  In this drawer-type heating cooker, a moving mechanism for moving the drawer relative to the cooker main body can be disposed in the lower part of the side surface space.

  As described above, according to the drawer-type heating cooker according to the present invention, since it is configured as described above, the following effects can be achieved. First, food can be uniformly heated by adopting a rotary table as a drawer. In addition, since a side feeding structure with a waveguide provided in the side space on the outside of the heating chamber is adopted, there is no need to place a waveguide on the ceiling, and heating is performed while suppressing the height of the heating cooker body. The ceiling of the room can be raised.

  Further, by arranging a moving mechanism for moving the drawer relative to the cooker main body at the lower part of the side part space, a space for the side feeding structure can be secured in the side part space, and the drawer In a state where the body is pulled out, the moving mechanism is located below the drawer body, and does not get in the way when the food is taken in and out of the drawer body, and the food can be easily taken in and out. Furthermore, by arranging the operation panel at the top of the door, the thickness of the ceiling can be reduced and the height of the heating chamber can be increased compared to the case where the operation panel is provided on the front of the ceiling. .

  Embodiments of a drawer-type cooking device according to the present invention will be described below with reference to the drawings. FIG. 1 is an external perspective view showing a state in which a drawer body is pulled out when the drawer-type heating cooker according to the present invention is a drawer-type microwave oven. FIG. 2 is a perspective view showing the drawer-type heating cooker shown in FIG. 1 with the drawer body stored.

  As shown in FIGS. 1 and 2, the drawer-type heating cooker 1 is housed in a heating cooker body 2 in which a heating chamber 3 to which microwaves are irradiated is provided, and in the heating chamber 3. A drawer body 4 that can be pulled out from the state (the state shown in FIG. 2) toward the outside of the heating cooker body 2 (the pulled-out state is shown in FIG. 1) is provided. The drawer body 4 includes an opening / closing door 5 at a front end portion thereof, and the opening 6 of the heating chamber 3 can be closed in a state where the drawer body 4 is housed in the heating cooker body 2.

  An operation panel 5b is provided on the upper part of the open / close door 5 provided in the front part of the drawer body 4 together with a handle 5a. By providing the operation panel 5b in the upper part of the open / close door 5, it is not necessary to provide the operation panel 5b on the front surface of the ceiling part 11 of the heating cooker body 2 as in the prior art. As a result, an increase in the height of the heating cooker body 2 can be suppressed. In addition, a window 5c through which the inside of the heating chamber 3 can be seen while preventing transmission of microwaves is provided on the front surface of the open / close door 5. A slide that allows the heating cooker body 2 to freely move the drawer body 4 between the side lower part of the door 5 that is the structure of the drawer body 4 and the lower part of the side surface space of the heating cooker body 2. A mechanism 18 is provided.

  FIG. 1 shows a state in which the movable rail 18 b constituting the slide mechanism 18 is attached to the lower side portion of the open / close door 5. The slide mechanism 18 is disposed outside the heating chamber 3 so as not to be affected by microwaves in the heating cooker, food residue, etc., for example, a movable rail attached to both sides of the open / close door 5. 18b and the fixed rail 18a which is attached to the cooking-cooker main body 2 side, and can slide to a movable rail can be provided. In this embodiment, the movable rail 18b is an elongate rail placed horizontally, and is slidably supported with respect to the fixed side rail 18a (see FIGS. 3 and 4) in the heating cooker body 2. ing. The fixed side rail 18a is driven in the direction of appearance from the inside of the heating cooker body 2 by the output of a motor which is a drive source provided in the heating cooker body 2. By this driving of the movable rail 18b, the drawer body 4 can be pulled out and stored in the heating chamber 3 of the heating cooker body 2 through the opening / closing door 5. By incorporating a drive mechanism such as a motor and a transmission mechanism for transmitting the output of the slide mechanism 18, the drawer body 4 can be automatically opened and closed.

  By adopting such a structure, in the drawer-type heating cooker of Patent Document 1, the fixed rail 18a provided at the substantially central portion in the height direction of the outer side surface of the heating chamber is on the extended line of the lower outer side surface of the heating chamber. Therefore, the side surface feeding mechanism can be arranged in the space occupied by the fixed rail 18a and the movable rail 18b.

  In FIG. 1, the drawer body 4 includes side walls 15, 15, a rear wall 16, and a bottom wall 17 on both sides having a low height, but only a part of each is depicted. The front end portions of the side walls 15 and 15 and the bottom wall 17 are attached to the open / close door 5. The upper part of the drawer body 4 is open, and in the state where the drawer body 4 is pulled out from the heating cooker body 2, an object to be cooked, for example, the tray T and the food F to be heated stacked on the drawer body 4 are drawn out. 4 can be taken in and out. Since the height of the side wall 15 is sufficiently lower than the height of the heating chamber 3, it is easy to take in and out food such as food from the side of the drawer 4.

  3 and 4 are schematic side views of the drawer-type heating cooker according to the present invention, FIG. 3 is a view showing the drawer body in a state of being pulled out, and FIG. 4 is the drawer body housed in the cooker body. It is a figure which shows a state. Elements equivalent to those depicted in FIG. 1 or FIG. 3 and 4 are for understanding the arrangement relationship seen from the side in explaining the side surface feeding structure.

  The rear wall portion 10 of the heating cooker body 2 includes a magnetron 7, a high-voltage transformer 9 (not shown in FIGS. 3 and 4) that supplies power to the magnetron 7, an electric power source including a high-voltage condenser, and the like. A component and a blower that blows and cools these electric components and further sends a part of the air that has cooled the electric components into the heating chamber 3 are provided.

  In a side surface space 50 (FIG. 1) outside the side of the heating chamber 3 and formed in the heating cooker body 2, microwaves generated by the magnetron 7 are transferred from the rear wall 10 to the heating chamber 3. A side feeding structure 51 by the waveguide 8 that guides is provided. Although the magnetron 7 is accommodated in the rear wall portion 10, an antenna for outputting generated microwaves is inserted into the waveguide 8 through an opening provided in the back of the waveguide 8. The microwave generated by the magnetron 7 is propagated into the waveguide. The microwave guided to the waveguide 8 in this way is irradiated into the heating chamber 3 from the side wall 13 (see FIG. 1) of the heating chamber 3.

  3 and 4, a rotary table 20 is rotatably disposed on the bottom wall 17 of the drawer body 4, and the upper surface of the bottom wall portion 12 and the storage state are provided on the cooking-cooker body 2 side. A driving mechanism 40 (details will be described later) for rotating the rotary table 20 is provided in a gap portion 19 formed between the drawer body 4 and the bottom wall 17. A fixed rail 18a of the slide mechanism 18 is fixed to the heating cooker body 2 below the side surface space 50, and a movable rail 18b attached to the open / close door 5 is slidably supported. About the weight of the drawer | drawing-out body 4 and a foodstuff, it can be supported in the heating chamber 3 by means (not shown), such as a roller, in the back, but is cooked by the movable rail 18b via the door 5 in the front. It is supported by the vessel body 2. A wiring structure (not shown) for supplying power and exchanging signals for the operation panel 5b is arranged through the fixed rail 18a and the movable rail 18b.

  Hereinafter, the rotary table drive mechanism employed in the drawer-type heating cooker according to the present invention will be described. FIG. 5 is a side sectional view of the drawer-type heating cooker, FIG. 6 is a side sectional view (a) and a plan sectional view (b) showing the drawer-type heating cooking apparatus shown in FIG. FIG. 8 is a side sectional view (a) and a plan sectional view (b) showing the drawer-type heating cooker shown in FIG. 5 in the housed state of the drawer body, and FIG. 8 is a bottom view of the drawer-type heating cooker including the rotary table drive mechanism. .

  A rotary table 20 that can freely rotate around a rotary shaft 21 is mounted on the upper center portion of the bottom wall 17 of the drawer body 4. On the turntable 20, a cooking object (the tray T and the food F to be heated) is placed. A rotary shaft 21 fixed to the rotary table 20 at the upper end portion 22 is provided below the rotary table 20. The rotary shaft 21 passes through the bottom wall 17 of the drawer body 4 and is below the drawer body 4. It extends to. Below the bottom wall 17, a drive gear 24 as a rotary table transmission portion is attached to the lower end portion 23 of the rotary shaft 21 in order to rotationally drive the rotary table 20 (details will be described later). In addition, a disk 25 is fixed to the rotary shaft 21 at an intermediate portion, and support shafts 26, 26, 26 extending at equal angular intervals (three directions every 120 degrees in this example) are attached to the disk 25. . Each shaft 26 is rotatably provided with a roller 27. The roller 27 is in contact with the rotary table 20 on the upper side and is in contact with the bottom wall 17 on the lower side, and the weight of the rotary table 20 and the cooking object is reduced. It is possible to roll on the bottom wall 17 while supporting the thickness.

  A motor 30 as an external drive source for driving the rotary table 20 is disposed at one corner in the bottom wall portion 12 of the heating cooker body 2. The output shaft 31 of the motor 30 extends through the bottom plate of the bottom wall portion 12 through the radio wave leakage structure and protrudes into the heating chamber 3. Therefore, the motor 30 is placed outside the heating chamber 3 and is not exposed to the microwaves irradiated into the heating chamber 3. An output gear 32 as a rotary motor transmission unit is attached to the upper end portion of the output shaft 31. Further, a sector gear 33 having a substantially fan shape is supported on the upper surface of the bottom wall portion 12 by a pivot 34 so as to be swingable therearound. The rotary shaft 21 of the rotary table 20 occupies an intermediate position between the pivot shaft 34 of the sector gear 33 and the output shaft 31 of the motor 30 when the drawer body 4 is in the retracted state.

  The sector gear 33 has an arcuate external gear portion 35 that always meshes with the output gear 32 to form a first engaging portion on the outer periphery side of the fan shape, and a sector shape at a midpoint between the pivot 34 and the outer periphery. And an arcuate internal gear portion 36 that forms a second engaging portion that meshes with the drive gear 24 on the inner peripheral side of the fan-shaped shape concentric with the outer periphery of the inner peripheral portion. The internal gear portion 36 is provided so as to be slightly offset in the axial direction, that is, upward from the sector-shaped main body of the sector gear 33 in order to be detachable in the horizontal direction. Further, the pivot 34 is located at a position near the opening 56 of the heating chamber 3 and does not interfere with the drive gear 24 that passes when the drawer body 4 is taken in and out. The output gear 32, the sector gear 33, and the drive gear 24 constitute a power transmission mechanism 40 for transmitting the output rotation from the motor 20 to the rotary table 20.

  The internal gear portion 36 for forming the second engaging portion has a pitch diameter having a sufficiently large radius of curvature as compared with the drive gear 24 of the rotating portion, and moves toward the moving direction of the drawer body 4. It is open. In a state where the drawer body 4 is housed in the heating cooker body 2, the drive gear 24 can be engaged with the internal teeth of the internal gear portion 36 with moderate accuracy by simply moving in the horizontal direction. When the body 4 is opened, it can be smoothly detached from the internal gear portion 36 by simply moving in the horizontal direction.

  In this way, the rotary table 20 is rotatably mounted on the bottom wall 17 of the drawer body 4, and the rotary shaft 21 of the rotary table 20 is protruded downward through the bottom wall 17 of the drawer body 4. A driving motor 30 is provided outside the bottom wall portion 12 of the heating chamber 3, and an output shaft 31 of the motor 30 is protruded upward through the bottom wall portion 12 of the heating chamber 3 through a radio wave leakage structure. The lower end portion 23 of the rotary shaft 21 of the rotary table 20 and the motor are formed in a gap portion 19 formed between the bottom wall 17 of the drawer body 4 of the drawer-type heating cooker 1 and the upper surface of the bottom wall portion 12 of the heating chamber 3. 20 output shafts 31 are disposed in a horizontal direction, and a drive gear 24 and an output gear 32 are disposed in an offset direction in the vertical direction.

  FIG. 9 is a perspective view showing a state in which the drawer body 4 is pulled out from the heating cooker body 2, and FIG. 10 is a perspective view showing a state in which the drawer body 4 is pushed into the heating cooker body 2. When the drawer body 4 is pushed into the heating cooker body 2, the drive gear 24 that appears outward from the bottom wall 17 of the drawer body 4 advances in the gap 19 on the bottom wall portion 12. In a state in which the drawer body 4 is completely pushed into the heating cooker body 2, the drive gear 24 meshes with the internal gear portion 36 of the sector gear 33.

  FIGS. 11 and 12 show how the drive gear 24 is rotationally driven after meshing with the internal gear portion 36 of the sector gear 33. FIG. 11 shows a state where the sector gear 33 is most oscillated clockwise, and FIG. 12 shows a state where the sector gear 33 is oscillated most counterclockwise. When the motor 30 is driven and the output shaft 31 and the output gear 32 attached thereto rotate, the sector gear 33 swings around the swing shaft 34 and the drive gear 24 that meshes with the internal gear portion 36 moves. Driven by rotation. When the rotation direction of the motor 30 is automatically reversed according to the position of the sector gear 33, the sector gear 33 repeatedly reverses the swing rotation within the swing range. The swing range of the sector gear 33 corresponds to one rotation of the drive gear 24.

  According to the structure of this embodiment, the floor surface of the drawer body 4 is raised by mounting the rotary table 20 on the drawer body 4, so that the ceiling height of the heating chamber 3 is relatively low. Therefore, the rotating antenna mounted on the top surface is not necessary, and the antenna rotating motor mounted on the upper portion of the waveguide 8 is not necessary. Thereby, since the fall of the ceiling height by the height of the turntable 20 is almost canceled, the food or tableware of the height comparable as the conventional drawer-type heating cooker can be used.

  When the drawer body 4 is pushed into the heating cooker body 2 to be accommodated and ready for cooking, the motor 30 is driven. By rotating the output of the motor 30 in reverse at predetermined rotation speeds, the output gear 32 swings and rotates the sector gear 33 meshing with the output gear 32 around the swing shaft 34 within a predetermined swing angle. By rotating the rotating shaft 21 of the drive gear 24 in the reverse direction, the rotary table 20 is rotated in reverse at successive predetermined angles. Although the turntable 20 reciprocally swings at a constant rotation angle without continuously rotating, the mounted cooking object almost completely covers the non-uniformly distributed microwave distribution area when reciprocatingly swings. Since it passes, the variation of the microwaves is leveled, and uniform heating substantially equivalent to that of the rotating table that rotates continuously becomes possible.

  In this way, uniform heating is possible by swinging and rotating the rotary table, so that there is a gap between the output gear 32 of the motor 30 located at one corner of the drawer and the drive gear 24 located near the center of the drawer. Power transmission can be performed by the sector gear 33 instead of the circular gear, and the sector gear 33 swings around a swing shaft 34 provided at one corner with respect to the motor 30 of the drawer.

  Further, the engagement of the drive gear 24 and the sector gear 33 is performed by meshing the arc-shaped internal gear portion 36 and the drive gear 24, but the arc-shaped external gear portion 35 is substantially equal to the rotary table. Since the reduction gear ratio has such a radius that the rotation ratio of the rotary table rotates once by the swing of the sector gear 33 within the mechanically swingable angle range, the arc-shaped inner teeth with a small curvature are realized. The drive gear 24 having a small outer shape meshes with the gear portion 36. For this reason, even if the position of the drive gear 24 varies in the width direction of the cooking device, it has a feature that the engagement is easy in the attaching / detaching operation.

  If the motor 30 has its own output rotation that is a continuous rotation, but a motor that reversely operates within a certain rotation angle due to a mechanical configuration, a motor having the necessary drive characteristics can be obtained at a low price. it can.

  In order to reversely rotate the output shaft 31 of the motor 30 at a predetermined number of rotations, the motor 30 can be a servo motor provided with a rotary encoder on the output shaft 31. The servo motor can be controlled at a high level and can acquire time-series data of the rotation angle. In the configuration using the servo motor, it is possible to calculate the rotational moment of the rotary table 20 loaded with food by processing the rotation angle data when driving with a constant rotational torque without performing feedback control. . Since this rotational moment has a strong correlation with the mass of food, the mass of food can be estimated and used for setting the cooking time during automatic cooking. Such automatic cooking is preferable because in addition to the detection of the finished product such as a humidity sensor, it is possible to prevent underheating or overheating when an extremely large or small amount of food is cooked.

  Since the rotation angle of the rotary table 20 is uncertain when the drawer body 4 is accommodated, if the engaging portion uses a gear, there is a possibility that the meshing between the two becomes inconsistent. By slightly moving the power transmission mechanism 40 with the horizontal moving force applied, it is possible to match the meshing of the two. Therefore, when the drawer body 4 is accommodated, it is always necessary to control the power transmission mechanism 40 to be slightly moved.

  In the power transmission mechanism 40 described above, the first and second engaging portions of the output gear 32, the sector gear 33, and the drive gear 24 are replaced with gears, and plastic teeth are formed on the inner peripheral surface of the arc-shaped elastic body. It can be set as the structure which affixed the attached belt. Such a toothed belt configuration is more preferable because the engagement between the two is less likely to become inconsistent.

  In the power transmission mechanism 40 described above, the first and second engaging portions do not mesh with the output gear 32, the sector gear 33, and the drive gear 24, and the friction wheel has a circumferential surface or an arc surface with a high friction coefficient. The frictional engagement between the two is more preferable because problems such as misalignment of gear meshing do not occur.

  Since the power transmission mechanism 40 in this embodiment is installed on the drawer body 4 or in the gap 19 between the drawer body 4 and the heating chamber 3 except for the motor installed outside the heating chamber 3, the cooking device The heating chamber 3 is installed. Therefore, the power transmission mechanism 40 is subjected to electromagnetic induction action by microwaves during cooking, but if a heat-resistant plastic, ceramic, heat-resistant glass or the like having a low dielectric loss is appropriately selected and used, problems such as discharge and overheating occur. It can be set as the structure which does not generate | occur | produce.

  By adopting a uniform heating mechanism using the turntable 20 according to the present invention, a rotating antenna that has been conventionally installed inside the waveguide disposed on the ceiling portion is unnecessary. When the rotating antenna is used, the rotating state cannot be visually confirmed. Therefore, the rotating state of the rotating antenna is confirmed by the electronic or optical rotation detecting means. However, such a confirming means is not necessary. Therefore, it is preferable. Further, since the rotating antenna is not necessary, the antenna rotating motor installed on the upper surface of the ceiling waveguide is not necessary. For this reason, it becomes possible to raise the heating chamber top surface by about 20 mm. As described above, the ceiling surface of the heating chamber 3 is finally raised by about 60 mm by measures such as the side feeding mechanism, the movement of the waveguide, the movement of the operation panel to the open / close door, and the downward arrangement of the side sliding mechanism. Therefore, the ceiling height which has been conventionally about 180 mm can be increased to 240 mm, and heating cooking can be performed while a heated object (food, beverage) is placed in a tall container.

  Since the pitch circle radius of the sector gear 33 of the power transmission mechanism 40 of the rotary table 20 is large, the curvature of the pitch circle is small, and the sector gear 33 is a receiving port with respect to the horizontal movement direction of the drawer 4. In addition, the positional relationship between the drawer body 4 and the heating chamber 3 is tolerant of displacement in the width direction, and the engagement / release of the gear of the rotary table and the sector gear 33 is easy.

  With such a configuration, when the user holds the door handle and performs the closing operation, a lateral operation force is applied to the drawer body, and even when the drawer body moves in an oblique direction, the fan-shaped gear of the rotary table gear Even if the position of the engagement with respect to the recess is shifted, it can be engaged without any particular problem.
