Description

  The present invention relates to a cooking device and a cooking system including the same, and more particularly, to a cooking device capable of performing cooking such as rice cooking without cooking unevenness, and a cooking system including such a cooking device. .

  The demand for cooking, represented by rice cooking, has increased with the increase in eating out and meals.For example, a large-scale cooking system for cooking rice that is processed into lunch boxes or rice balls has a large scale. In addition to the fine details such as high-mix low-volume rice cooking, efficiency and energy saving are desired.

  Under such circumstances, a surface combustion burner has attracted attention because of its good thermal efficiency, and has recently been frequently used as a heating source in commercial cooking devices such as rice cookers. Incidentally, as is well known, a surface combustion burner uses, as a burner plate, a porous member made of ceramic or metal fiber having pores communicating front and back sufficient to allow the combustion gas mixture to diffuse and pass through. This is a type of burner in which a combustion gas mixture is supplied from the back surface of the burner and burned on the surface of the burner plate.

  As a rice cooker which uses a surface combustion burner as a heat source, there exist some which were indicated by patent documents 1-2, for example. In these rice cooking apparatuses, the burner plate of the surface combustion burner is radially arranged at a position facing the bottom surface of the rice cooking pot set at the rice cooking position, and rice cooking is performed by heating the bottom surface of the rice cooking pot. However, in the surface combustion burner, since combustion energy is immediately transmitted as radiant heat to a cooking container such as a rice cooker, there is a disadvantage that uneven cooking such as uneven rice cooking is likely to occur. In order to solve this drawback, for example, in Patent Document 3, by opening a secondary air port in the vicinity of the surface of the burner plate of the surface combustion burner, the surface combustion burner enables flammable combustion with a flame and is high. There has been proposed a cooking device that suppresses the occurrence of uneven cooking such as uneven rice cooking while maintaining thermal efficiency. However, in the cooking device of Patent Document 3, it is necessary to open a secondary air port in the vicinity of the surface of the burner plate, and there is a disadvantage that the structure of the burner part of the cooking device is particularly complicated.

  The present invention was made in order to eliminate the disadvantages and inconveniences of the conventional cooking device as described above, and it is possible to realize cooking without cooking unevenness such as rice cooking unevenness with a simple structure. It is an object of the present invention to provide a cooking apparatus and a cooking system including such a cooking apparatus.

  As a result of diligent research to solve the above problems, the present inventor has caused the heat generating portions such as the burner plates arranged radially to swing and rotate in the radial circumferential direction around the radial center. Thus, it has been found that heating unevenness with respect to cooking containers such as rice cooking pots can be eliminated and cooking without cooking unevenness such as rice cooking unevenness can be realized.

  That is, the present invention comprises a heating means comprising a plurality of heat generating portions arranged radially at intervals in a circumferential direction at a position facing the bottom surface of the cooking container when the cooking container is set at a heated position. The above-described problems are solved by providing a cooking device having a swing rotation mechanism that swings and rotates the plurality of heat generating portions in the circumferential direction around the radial center. Moreover, this invention solves said subject by providing the heat cooking system provided with two or more such heat cooking apparatuses.

  According to the heating cooking apparatus of the present invention, the plurality of heat generating portions arranged at intervals in a radial manner swing and rotate in the radial circumferential direction with the radial center as an axis. It becomes possible to heat the bottom surface of the container more evenly, and cooking unevenness such as rice cooking unevenness can be eliminated. The swing rotation angle of the heat generating part is not particularly limited as long as uniform heating is possible, but if the swing rotation angle is too small, the effect of the swing rotation does not appear significantly. The angle of rotation is preferably 1/3 or more, more preferably 1/2 or more of the angle between two heat generating portions adjacent in the circumferential direction. On the other hand, even if the swing rotation angle is too large, the swing rotation mechanism cannot be expected to have a significant difference in the effect of the swing rotation. Is less than an angle between two heat generating portions adjacent in the circumferential direction.

  Moreover, as a heating means used with the heating cooking apparatus of this invention, what kind of heating means may be sufficient if it can supply calorie | heat amount required for heating cooking, such as rice cooking, to cooking containers, such as a rice cooking pot, For example, when a surface combustion burner having a plurality of burner plates radially arranged at intervals in the circumferential direction is used as a heating unit, the cooking container is maintained while maintaining high thermal efficiency by the surface combustion burner. It becomes possible to heat the bottom of the plate uniformly to realize cooking without uneven cooking.

  Furthermore, there is no particular limitation on the cooking that is the subject of the present invention. Basically, any cooking is possible as long as cooking is performed by putting a material to be cooked in a cooking container and heating it. However, the cooking device of the present invention is preferably applied to cooking that does not stir the cooking material other than convection in the container by the supplied heat during cooking. It is preferable to apply to cooking rice. When the cooking device of the present invention is applied to rice rice cooking, the cooking container is a rice cooker, and when the cooking container is set at the heated position, when the rice cooking pot is set at the rice cooking position It turns out that.

  According to the heating and cooking apparatus of the present invention, even when a heating means including a plurality of heat generating portions arranged radially at intervals in the circumferential direction is used, cooking without heating unevenness can be realized. It becomes possible. In particular, when a surface combustion burner having a plurality of burner plates arranged radially at intervals in the circumferential direction is used as the heating means, the surface combustion burner has high thermal efficiency and no cooking unevenness such as rice cooking unevenness. The advantage that heat cooking can be made compatible is obtained. Moreover, according to the heating cooking system of the present invention comprising a plurality of heating cooking apparatuses of the present invention, there is an advantage that cooking without uneven cooking such as uneven rice cooking can be performed continuously and efficiently. It is done.

In this example, the heating means 5 is a surface combustion burner, and 6c and 6g are burner plates which are the heat generating parts. As shown in FIG. 1, the burner plates 6 c and 6 g are installed at positions facing the bottom of the rice cooking pot 2 set at the heated position, that is, the rice cooking position. In addition, since the heating means 5 is a surface combustion burner, it cannot be overemphasized that the burner plates 6c and 6g are the porous bodies which have the pore which allows mixed gas to pass through inside. 7 is a mixed gas distribution chamber, 8 is a connection port, and the connection port 8 is connected to a mixed gas source 11 via a flexible tube 9 and a pipe 10.

  The mixed gas source 11 forcibly mixes fuel gas such as natural gas or city gas and air and supplies the mixed gas to the heating means 5. The flow rate of the mixed gas supplied to the heating means 5 and the mixed gas The ratio of the fuel gas to the air is determined according to the time course from the start to the end of cooking, or according to the type of rice to be cooked, such as white rice, brown rice, vinegared rice, etc. It can be changed as appropriate based on the above. The flexible pipe 9 may have any flexibility as long as it is capable of allowing the connection port 8 to swing and rotate with respect to the fixed pipe 10 while having a mixed gas passage inside. There are no particular restrictions on the structure or material.

  Reference numeral 12 denotes a rotary cylinder, and the rotary cylinder 12 is supported by rotary bearings 13 and 13 so as to be rotatable around a vertical axis. Reference numeral 14 denotes a swing lever attached to the rotary cylinder 12, and a pin 15 is attached to the swing lever 14 with its tip end upward. Reference numeral 16 denotes a connecting body, and the connecting body 16 is rotatably attached to the swing lever 14 by inserting a pin 15 into a hole at the tip thereof. The heating means 5 is connected to the rotating cylinder 12, and when the swing lever 14 is swung in a direction perpendicular to the paper surface in FIG. The rotating cylinder 12 is oscillated and rotated about a vertical axis, and the heating means 5 is also oscillated and rotated about a vertical axis along with the oscillating rotation. Reference numeral 17 denotes a temperature sensor. The temperature sensor 17 is always urged upward by elastic means such as a spring so that the tip of the temperature sensor 17 comes into contact with the bottom surface of the rice cooking pot 2 set at the rice cooking position. The temperature signal detected by the temperature sensor 17 is supplied to the control device 19 that controls the operation of the rice cooking device 1 via the signal line 18. 20c and 20g are in contact with the lower surface of the lower bowl of the rice cooker 2 and leave a space between the lower surface of the lower bowl and the upper surface of the furnace 3, and the rice cooker 2 is placed in a predetermined rice cooking position. It is a spacer for setting. 21 is a column of the rice cooker 1 and 22 is a frame.

  FIG. 2 is a plan view of FIG. 1 (however, the rice cooker 2 is omitted). As shown in FIG. 2, the surface combustion burner which is the heating means 5 has eight burner plates 6a to 6h, and the burner plates 6a to 6h are evenly spaced apart from each other by 45 degrees in the circumferential direction. They are arranged radially. In the surface combustion burner of this example, the number of burner plates is eight, but it is needless to say that the number of burner plates which are heat generating parts is not limited to eight. However, from the viewpoint of uniformly heating the bottom surface of the rice cooking pot 2 as a cooking container, it is preferable that the number is at least 2 or more, preferably 4 or more, and they are equally arranged at the same angular interval. It is preferable. If the arrangement is uniform, two or more types of burner plates having different shapes and sizes may be mixed. Eight spacers 20a to 20h are evenly arranged on the upper surface of the furnace 3 with an interval of 45 degrees from each other.

  FIG. 3 is a partial enlarged cross-sectional view showing only the heating means 5 of FIG. 1 and the vicinity thereof. 23c and 23g are space portions corresponding to the burner plates 6c and 6g, respectively, and the space portions 23c and 23g communicate with the distribution chamber 7 via the corresponding mixed gas passages 24c and 24g. Reference numeral 25 denotes a perforated plate that divides the inside of the distribution chamber 7 into an outer peripheral portion and an inner peripheral portion. The mixed gas of air and fuel gas supplied from the mixed gas source 11 shown in FIG. 1 to the outer periphery of the distribution chamber 7 via the pipe 10 and the flexible pipe 9 gives a certain flow path resistance by the perforated plate 25. Then, it reaches the entire circumference of the distribution chamber 7, and is guided from the inner periphery of the distribution chamber 7 to the space portions 23c and 23g through the mixed gas passages 24c and 24g. The mixed gas guided to the space portions 23c and 23g is ejected from the respective burner plates 6c and 6g, and is ignited by an appropriate ignition means so as to burn on the surfaces of the burner plates 6c and 6g. Reference numeral 26 denotes a protective tube for accommodating the signal line 18 connected to the temperature sensor 17 therein.

It is delimited by a plate 25. The mixed gas passages 24a to 24h communicate with the space portions 23a to 23h located immediately below the burner plates 6a to 6h, respectively.

  5 is a cross-sectional view taken along the line Y-Y 'of FIG. For convenience, the outline of the heating means 5 is indicated by a broken line. In FIG. 5, reference numeral 27 denotes an electric motor, which is attached to the columns 21 and 21. A drive disk 28 is connected to the output shaft of the electric motor 27 via an appropriate speed reduction mechanism. One end of the coupling body 16 is rotatably attached to the outer peripheral portion of the drive disk 28 via a pin 29. Reference numeral 30 denotes a long hole provided in the swing lever 14, and a pin 15 is temporarily fixed at an appropriate position of the long hole 30, and the other end of the coupling body 16 is freely rotatable on the pin 15. It is attached. The electric motor 27, the drive disk 28, the coupling body 16, the rocking lever 14, and the pins 15 and 29 form a rocking and rotating mechanism that rocks and rotates the burner plates 6 a to 6 h that are the heat generating parts of the heating unit 5. ing.

  6 is a partially enlarged cross-sectional view showing only the vicinity of the swing lever 14 and the coupling body 16 in FIG. In FIG. 6, reference numeral 31 denotes a nut, and reference numeral 32 denotes a washer. Normally, the pin 15 is fixed at an appropriate position of the long hole 30 by setting the nut 31 in a tightened state. By loosening the nut 31, the pin 15 can be moved to an appropriate position along the long hole 30. If the nut 31 is tightened at the moved position, the pin 15 is fixed at that position. be able to. As described above, the fixing position of the pin 15 can be changed along the long hole 30, whereby the swing angle of the swing lever 14 can be changed. That is, if the fixed position of the pin 15 is closer to the rotating cylinder 12 that is the base of the swing lever 14, the swing angle of the swing lever 14 is increased, and the pin 15 is moved closer to the tip of the swing lever 14. In this case, the swing angle of the swing lever 14 is reduced. A connecting body 16 is inserted into the tip of the pin 15, and the connecting body 16 is rotatable with respect to the pin 15, in other words, with respect to the swing lever 14.

  Next, the operation of the swing rotation mechanism of this example will be described with reference to FIGS. First, in the state shown in FIG. 7, the pin 29 for rotatably locking the coupling body 16 is at the uppermost position in the drawing of the drive disk 28, and the swing lever 14 is at (1) in the drawing. It is in the position of the swing angle “0” shown. From this state, when the electric motor 27 operates to rotate the drive disk 28 by 90 degrees in the direction of the arrow in the figure, the pin 29 moves to the position shown in FIG. As the pin 29 moves, the connecting body 16 also moves downward in the figure, and the swing lever 14 together with the rotary cylinder 12 to which the swing lever 14 is fixed has a swing angle “α” shown in FIG. ”To the position“ ”.

  When the drive disk 28 is further rotated 90 degrees from the state of FIG. 8, the pin 29 moves to the lowest position in the figure of the drive disk 28 as shown in FIG. Rotates together with the rotating cylinder 12 to the position of the swing angle “β” indicated by (3) in FIG. The position of FIG. 9 where the pin 29 is at the lowermost part of the drive disk 28 is the position where the swing angle of the swing lever 14, that is, the swing angle of the rotary cylinder 12 is maximized.

  Subsequently, when the drive disk 28 further rotates 90 degrees, the pin 29 moves to the position shown in FIG. 10, and along with this movement, the swing lever 14 changes the rotation direction, together with the rotating cylinder 12. It returns to the position of the swing angle “α” shown in the middle (2). When the drive disk 28 further rotates 90 degrees, the pin 29 moves again to the uppermost position in the drawing of the drive disk 28 as shown in FIG. 11, and the swing lever 14 together with the rotary cylinder 12 It returns to the original position indicated by middle (1). Thereafter, as the drive disk 28 rotates, the swing lever 14 repeats swing rotation of (1) → (2) → (3) → (2) → (1). The connected rotating cylinder 12 and the burner plates 6a to 6h, which are the heat generating parts in the heating means 5, also repeat swinging rotation in the range of angles “0” to “β”.

  FIG. 12 is a plan view showing a state of swinging rotation of the burner plates 6a to 6h which are heat generating portions. As shown in the figure, the burner plates 6a to 6h, which are heat generating parts, swing and rotate in a radial circumferential direction indicated by a double arrow between a position indicated by a solid line and a position indicated by a broken line in the figure. Since the rotation center of the rotary cylinder 12 coincides with the radial center of the burner plates 6a to 6h that are the heat generating portions, the above-described swinging rotation of the burner plates 6a to 6h that are the heat generating portions is the radial rotation. The process is performed in the radial circumferential direction with the center as the axis.

  Thus, in the rice cooking device 1 of the present invention, the burner plates 6a to 6h, which are the heat generating parts in the heating means 5, are operated within the range of the swing angle “0” to “β” by operating the swing rotation mechanism. Since it swings and rotates, a wider range of the bottom surface of the rice cooker 2 that is a cooking container is heated to face the burner plates 6a to 6h that are the heat generating portions, and the burner plates 6a to 6h that are the heat generating portions are heated. The generated heat is more evenly transmitted to the bottom surface of the rice cooker 2. For this reason, according to the rice cooking apparatus 1 of this invention, a heating nonuniformity is reduced significantly and it becomes possible to implement | achieve the heat cooking without cooking nonuniformity, such as a rice cooking nonuniformity.

  Further, the swing angle “β” of the burner plates 6a to 6h as the heat generating portion changes the fixing position of the pin 15 with respect to the swing lever 14 along the long hole 30 as described above with reference to FIG. It can be changed as appropriate. From the viewpoint of heating the bottom surface of the rice cooker 2 that is a cooking container more evenly, the swing angle “β” is 1/3 of the angle between two heat generating portions adjacent in the circumferential direction, that is, the burner plate. The above is preferable, and more preferably 1/2 or more. Further, even if the swing angle “β” is too large, the structure of the swing rotation mechanism becomes complicated, and the uniformity of heating is not significantly improved for a large scale. "Is preferably at most equal to or less than the angle between two heat generating portions adjacent in the circumferential direction, that is, the burner plate. In this example, there are eight burner plates 6a to 6h, and the angle between two burner plates adjacent in the circumferential direction is 45 degrees. Therefore, the swing angle “β” is 15 degrees (= 45 degrees × (1/3)) to 45 degrees or less, more preferably 22.5 degrees (= 45 degrees × (1/2)) to 45 degrees or less.

  In addition, the period for swinging and rotating the heating unit is not particularly limited as long as the bottom surface of the rice cooker 2 that is a cooking container can be heated uniformly, but basically, during the entire cooking time, The rocking rotation may be performed at least 5 times, more preferably 10 times or more, and still more preferably 20 times or more. For example, in the case of rice cooking, if the normal rice cooking time is 20 minutes, it is once every 4 minutes to rotate and rotate at least 5 times during the rice cooking period, more preferably once every 2 minutes to rotate and rotate 10 times. More preferably, in order to rotate 20 times, the rotation may be performed at a cycle of once per minute. The period of swinging rotation means a period until the heat generating portion returns from the initial position to the initial position again.

  Moreover, the period of the rocking rotation may be constant during the whole cooking period or may be changed. For example, in the case of rice cooking, heating is performed with a relatively high fire until the middle of the rice cooking period, and heating is performed with a relatively low heat in the latter period, but in accordance with the strength of the thermal power supplied by the heating means, In this case, the oscillation rotation cycle is shortened to be, for example, once every 2 minutes, and in the case of low fire, the oscillation rotation cycle is increased to be once every 3 minutes. good.

  It should be noted that the operation start and / or end of the swing rotation mechanism is preferably linked with the operation start and / or end of the heating means 5. That is, the swing rotation mechanism operates in conjunction with the start of heating by the heating means 5, or the swing rotation mechanism stops operating in conjunction with the end of heating by the heating means 5, or both. Is preferred.

  As mentioned above, although this invention was demonstrated to the case where a surface combustion burner is used as the heating means 5, the heating means in the heating cooking apparatus of this invention is not restricted to a surface combustion burner. Any heating means may be used as long as the heating portions can be arranged radially at intervals in the circumferential direction. For example, the heating means includes a heating wire such as a sheathed heater as the heating portion. Even if it is a Bunsen burner or a surface combustion burner having a secondary air port disclosed in Patent Document 3, for example, superheated steam is jetted out and the rice cooker 2 is heated by the superheated steam. It may be what you do.

  FIG. 13 is a diagram illustrating another example of the swing rotation mechanism. In FIG. 13, a rotating wheel 33 is attached to the tip of the swing lever 14, and a cam 34 is in contact with the rotating wheel 33. Reference numeral 35 denotes a rotating shaft of the cam 34. The swing lever 14 is always urged downward in the figure by elastic means (not shown). In this state, when the cam 34 is driven to rotate around the rotation shaft 35 by an appropriate driving means, the swing lever 14 that is in contact with the cam 34 via the rotating wheel 33 has a circumference indicated by an arrow in the figure. Oscillates and rotates in the direction. By adjusting the size and shape of the cam 34 and the position with respect to the swing lever 14, the swing angle of the swing lever 14 can be adjusted. In this example, the swing lever 14, the rotating wheel 33, and the cam 34 form a swing rotation mechanism.

  FIG. 14 is a diagram illustrating still another example of the swing rotation mechanism. In FIG. 14, 36 and 37 are gears, and 38 is a rotational power transmission mechanism. As shown in the figure, the gear 36 is attached to the rotary cylinder 12, and a gear 37 is engaged with the gear 36. When the electric motor 27 is driven in this state, the rotation is transmitted to the gear 37 via the rotational power transmission mechanism 38, the gear 37 rotates, and the gear 36 and the rotating cylinder 12 rotate with this rotation. The rotation direction of the electric motor 27 is switched at regular time intervals or constant rotation speeds, or the rotation direction switching mechanism built in the rotational power transmission mechanism 38 is switched at regular time intervals or constant rotation speeds. The rotating cylinder 12 can be swung and rotated by switching the rotation direction. Further, by changing the timing for switching the rotation direction of the gear 37, the angle of rocking rotation of the rotary cylinder 12 is changed, for example, the rotation speed of the electric motor 27 is changed, or the rotation power transmission mechanism 38 is built in. By changing the deceleration rate of the speed reduction mechanism, the period of swinging rotation of the rotary cylinder 12 can be changed. In this example, the electric motor 27, the rotational power transmission mechanism 38, and the gears 36 and 37 form a swing rotation mechanism.

  The rice cooker that has left the rice cooking / steaming unit 107 is again covered with the lid removing device 105, and the taken lid is sent to the first lidding device 102 through the lid cleaning device 109. On the other hand, the rice cooker with the lid removed proceeds to the direction switching device 110, where it is reversed by the rice take-out device 111, and the cooked rice is taken out from the rice cooker. The taken out cooked rice is stirred by the cooked rice stirrer 112 and, after stirring, is sent out to the transport device 113. Reference numeral 114 denotes a weighing device, which measures a predetermined amount of the cooked cooked rice and sends it to the subsequent transfer device 113. The fed cooked rice is stored in a container by a palletizer 115 and stacked. On the other hand, the cooked rice cooker that has been emptied by the cooked rice take-out device 111 is switched by 90 degrees in the direction of travel by the direction switching device 110 and is conveyed to the cooker washing device 116 where it is washed and washed.
