Description

  The present invention relates to a food cooking apparatus that is suitable for automatic cooking of food and can be used for home use or business use.

  Conventionally, as can be seen in, for example, Patent Document 1, food cooking is configured such that a rotating stirring bar is inserted into a horizontally rotating pan placed on the heating means of the main unit base, and the food put in the pan is fried while stirring. There was a device. Examples of the heating means include a gas stove and an electromagnetic heating cooker. This food cooking device is an automatic device that cooks food without requiring a cook, and has a labor-saving effect. The power for horizontally rotating the pan and the power for rotating the stirring bar are provided from independent drive sources. This has the advantage that the rotation speed of the pan and the rotation speed of the stirring bar can be individually adjusted or set.

  Further, Patent Document 2 proposes a food cooking apparatus provided with a control unit that can set various settings, a plurality of menu selections, cooking number settings, and cooking time, pan rotation number, and stirring bar rotation number. Has been. Thereby, the effect which comes to be able to achieve further automation as a food cooking device which does not require a chef is acquired.

Japanese Patent Laid-Open No. 06-261831 (2 pages, FIG. 1 and FIG. 2) JP 2003-290045 A (pages 2 and 3; FIGS. 1 and 2)

  The food cooking apparatus as described above can be miniaturized and preferably is more automated. However, with the miniaturization or automation, a fine problem has arisen. For example, when the food cooking device of Patent Document 1 was examined for downsizing, it was found that there is a problem that the downsizing is hindered in that separate drive sources are used for the rotary pan receiver and the stirring bar. However, if the horizontal rotation of the pan is fast, it is preferable that the rotation of the stirring bar is fast, and if the horizontal rotation of the pan is slow, the rotation of the stirring bar is preferably slow. It has also been found that the need to adjust the speed independently is low. Therefore, the first purpose is to reduce the size of the cooking apparatus by using both of the drive sources, and a configuration that can release the connection between the drive source and the stirrer as necessary has been studied.

  Moreover, it becomes difficult to finely adjust the posture or arrangement of the stirrer by combining the driving source of the rotating pan receiver and the stirrer, depending on the size or shape of the pan used to support the rotating pan receiver. This makes it impossible to place the stirring bar in an appropriate posture. This is a problem that also occurs in a spatula provided separately from or in parallel with the stirrer. Therefore, the second object is to allow proper food agitation and assembling even if the size or shape of the pan supported by the rotating pan receiver is different while fixing the arrangement of the stirrer and the gathering spatula. The structure of the stir bar and the spatula was studied.

  In addition, the automation of food cooking equipment means automatic cooking that heats and stirs food in a rotating pan, but if the posture of the pan changes during this automatic cooking, the pan is rotated by a rotating pan receiver. Not only becomes unstable, but also there is a possibility that the food cannot be agitated by the stirrer and cannot be gathered by the spatula. In addition, the change in the position of the pan also means that the heating position of the pan by the heating means changes, and as a result of the inability to efficiently use heat, there is a problem that wasteful heating power is required and the cooking time of food is increased. . Therefore, a third object of the present invention was to realize automatic cooking in which the posture of the pan is kept horizontal in response to miniaturization or automation of the food cooking device.

  What was developed in order to solve the first purpose is that the main body base is provided with a rotating pan receiver that rotates horizontally and a heating means for the pan that rotates horizontally on the rotating pan receiver, and rotates in the pan. In the food cooking device that supports the stirrer that stirs the food in the pan on the main unit base, the horizontal rotation power is transmitted by the pan transmission mechanism from the output shaft of the drive source provided on the main unit base to the rotary pan receiver, It is a food cooking device in which rotation power is transmitted from the output shaft to the stirrer by a transmission mechanism for the stirrer so that the horizontal rotation of the rotating pan receiver and the rotation of the stirrer are linked. The food cooking device of the present invention is mainly suitable for cooking food in a pan, but can also be used for stewed cooking or soup cooking that requires stirring, for example.

  The food cooking device of the present invention also serves as a drive source for the rotary pan receiver and the stirrer by assigning the rotational power transmission mechanism separately to the pan transmission mechanism and the stirrer transmission mechanism. Thereby, the part which a cook needs to operate reduces, for example, the structure of a control part as seen in patent document 2 is simplified, and there exists an advantage that operation itself becomes easy. The pan transmission mechanism is composed of a rotating disk that is fixed to the output shaft of the drive source and rotates vertically, and an annular plate that is provided below the rotating pot receiver and rotates horizontally, and presses the rotating disk against the annular plate. Thus, it is preferable that the rotational power is transmitted through the output shaft, the rotating disk, and the annular plate to horizontally rotate the rotating pan receiver. The configuration in which the rotational power from the drive source is transmitted by the pressure contact between the rotating disk and the annular plate has a function of reducing noise during rotation of the rotating pan receiver that supports the pan that is filled with food and becomes a heavy object.

  Further, the transmission mechanism for the stirrer includes an output shaft of the drive source, a stirrer-side driven gear that is fixedly rotated on the rotation shaft of the stirrer, and a transmission member that interlocks the output shaft and the stirrer-side drive gear. Rotating power is transmitted through the output shaft, transmission member, stirrer side drive gear, stirrer side driven gear, and rotation shaft by meshing the stirrer side drive gear of the transmission member and the stirrer side driven gear of the stirrer. And the structure which rotates a stirring bar is good. The transmission member may be a transmission chain, a transmission belt, or a transmission shaft. Although these transmission members can be directly wound around the output shaft, it is preferable to fix the output sprocket to the transmission chain, the output pulley to the transmission belt, and the output gear to the output shaft.

  The transmission chain or transmission belt in the transmission mechanism for the stirrer can bend the rotational direction of the rotational power, and has the advantage of freeing the positional relationship of the stirrer with respect to the drive source. However, as the food cooking device becomes smaller, the transmission direction of the rotational power becomes difficult to bend even by the transmission chain or transmission belt, and the tension of the transmission chain or transmission belt changes to make the rotation of the stirrer unstable. . Therefore, the transmission mechanism for the stirrer includes an output side drive gear that is fixed to the output shaft of the drive source and rotates vertically, a stirrer side driven gear that is fixedly rotated to the rotation shaft of the stirrer, an output side driven gear, and It consists of a transmission shaft to which the stirrer side drive gear is fixed, meshing the output side drive gear of the output shaft and the output side driven gear of the transmission shaft, and the stirrer side drive gear of the transmission shaft and the stirrer side driven of the stirrer By meshing with the gear, the rotational power is transmitted via the output shaft, the output side drive gear, the output side driven gear, the transmission shaft, the stirrer side drive gear, the stirrer side driven gear, and the rotating shaft, and the stirrer is rotated. The structure to be made is preferable. This transmission mechanism for the stirrer changes the transmission direction of the rotational power by the meshing output side drive gear and output side driven gear, the stirrer side driven gear and the stirrer side drive gear, and drives the rotational power by the transmission shaft. Transmit in a certain direction and a certain distance from the source.

  Here, the stirrer has a stirrer-side driven gear fixed to the rotating shaft, and the stirrer-side driving gear that transmits the rotational power from the output shaft of the drive source provided in the main unit base is used as the stirrer-side driven gear. And the rotational power is transmitted to the stirrer, and the stirrer-side driven gear may be freely disconnected from the stirrer-side drive gear. As a result, a stirrer-side driven gear and a stirrer-side drive gear that are engaged with each other are provided in a part of the transmission mechanism for the stirrer, and both the gears can be disconnected, thereby being used as a rotating pan receiver. Only the stirrer can be disconnected from the drive source. That is, it is possible to stop the rotation of the stirrer by cutting off the transmission of the rotational power from the drive source while rotating the pan supported by the rotating pan receiver.

  Specifically, the stirrer is supported by the gear box by projecting the rotating shaft into a gear box that can be moved up and down in the vertical direction, and the stirrer-side driven gear is fixed to the rotating shaft that projects into the gear box, A stirrer-side drive gear that transmits rotational power from an output shaft of a drive source provided on the main body base is provided in the gear box, and the stirrer-side drive gear and the stirrer driven gear are engaged with each other. It is good to make it the structure which transmits rotational power to this stirrer, and makes a stirrer side driven gear freely disconnectable with respect to a stirrer side drive gear by making a gear box raise / lower freely with a stirrer. Thereby, the transmission of the rotational power from the drive source can be connected to or released from the rotor only by raising and lowering the gear box without touching the stirrer side drive gear and the stirrer driven gear during the transmission of the rotational power. Can do. Here, the raising / lowering of the gear box includes not only a case where the gear box moves up and down linearly but also a case where the gear box moves in a positional relationship where the stirrer side drive gear and the stirrer driven gear are separated. This includes the case where the stirrer driven gear moves and is separated from the stirrer side drive gear.

  In this case, the gear box is movable up and down with respect to the elevator base, a connection position where the stirrer-side driven gear meshes with the stirrer-side drive gear, and a release position where the stirrer-side driven gear releases from the stirrer-side drive gear. It is preferable to have a moderation mechanism that engages with the elevator base alone, and that this moderation mechanism is operated to release the engagement with a lever provided in the gear box. The lever is an operating means for assisting the raising and lowering of the gear box and for engaging and releasing the moderation mechanism. The moderation mechanism prevents the connection or release in the stirrer-side transmission mechanism from becoming insufficient, and allows the gear box to move up and down between the reliable connection position and the release position. As a specific moderation mechanism, a retractable protrusion is connected to a wire that can be pulled by a lever, and the protrusion is engaged with an engagement hole provided in a gear box corresponding to each of a connection position and a release position. The configuration can be exemplified.

  Next, what was developed in order to solve the second purpose is to provide a rotating pan receiver that rotates horizontally and a heating means for the pan that rotates horizontally on the rotating pan receiver, In a food cooking device that rotates and stirs the food in the pan on the main body, the stirrer consists of a stirring body that stirs the food in the pan and a rotating shaft that supports the main body. The stirrer body is a food cooking device that is elastically supported on a rotating shaft. In this case, it is preferable that the stirrer body is detachable from the rotating shaft. Specifically, the structure which interposes a coil spring in either a rotating shaft or a stirring element main body, or the structure which connects a rotating shaft and a stirring element with a coil spring can be illustrated. The stirrer body is elastically supported by a coil spring with respect to the rotating shaft. Moreover, what is necessary is just to make the stirring bar main body with respect to a rotating shaft detachable with respect to the coil spring before and behind or a coil spring.

  Even if the size or shape of the pan supported by the rotating pan receiver changes, the stirrer that elastically supports the main body of the stirrer changes its position or position by the elastic support part (e.g., the coil spring), and excessively Without being pressed against the pan, it can bring a moderate hit to the food. From now on, it is good to make the stirring bar main body into the attitude | position pushed down toward the pan previously. Further, when a stirrer body made of a spiral bar along the conical side surface with the rotation axis as the central axis and having protrusions provided at appropriate intervals on the bar is used, the stirrer body elastically supported by the rotation shaft Stir the food better.

  Similarly, what was developed in order to solve the second purpose is that the main body base is provided with a rotating pan receiver that rotates horizontally and a heating means for the pan that rotates horizontally on the rotating pan receiver, and moves according to the pan. In the food cooking device that supports the main body machine base with a spatula that moves toward the center of the food in this pan, the front spatula moves the food in the pan to prevent scorching against the pan, and the main body base The spatula plate is a food cooking device that is supported by the spatula support portion. Specifically, the structure which interposes a coil spring in either a spatula support part or a spatula board, or the structure which connects a spatula support part and a spatula board with a coil spring can be illustrated. The spatula plate is elastically supported by a coil spring with respect to the spatula support portion. Moreover, what is necessary is just to make the spatula board with respect to a spatula support part detachable with respect to the coil spring before and behind or a coil spring.

  The spatula that elastically supports the spatula plate to the spatula support part changes the posture or position by the elastic support part (e.g. the coil spring) even if the size or shape of the pan supported by the rotating pan receiver changes, and excessively The food that moves according to the pan can be moved along the spatula without being pressed against the pan. Thereby, a foodstuff can remain in a fixed position with respect to a pan, and it can prevent scorching. Also, if the spatula plate is offset from the radial direction of the pan and the center side of the pan of this spatula plate is tilted downstream in the rotation direction of the pan, the food will move toward the center of the pan along the spatula plate. Can do. This has the function which can heat food efficiently using the heat of a heating means by heating the center of a pan intensively.

  Unlike the stirrer, the lifting spatula does not need to be raised or lowered to stop the rotation, but it is desirable that the spatula can be retracted from a predetermined position, for example, when replacing a pan or maintaining a food cooking device. From this point, it is preferable that the spatula makes the spatula support part ascendable and descendable with respect to the main body base, and if necessary, the spatula plate can be raised and lowered together with the spatula support part. In this case, if the stirrer is supported on the gear box as described above, the stirrer and the shifting spatula can be moved up and down integrally by providing a spatula support portion on the gear box.

  Finally, what was developed in order to solve the third object is to provide a rotating pan receiver that rotates horizontally and a heating means for the pan that rotates horizontally on this rotating pan receiver, In a food cooking device that protrudes a stir bar or a spatula from the main body base, the dedicated pan for the rotating pan receiver is supported by the rotating pan receiver supporting the engaging portion of the dedicated pan provided with an engaging portion on the outer surface. It is the food cooking device which kept the attitude | position of horizontal. The dedicated pan can be rotated without breaking the horizontal posture even when the food is stirred by the stirrer or the food by the spatula by being supported by the rotating pan holder via the support portion provided on the outer surface. Here, “horizontal” of the dedicated pan means that the peripheral edge of the dedicated pan is horizontal.

  For example, the dedicated pan may be engaged with an upper portion of the cylindrical rotary pan receiver by placing an engaging portion on the upper edge and supported by the rotary pan receiver. However, since the upper edge of the rotating pan receiver does not restrict the engaging portion in the horizontal direction, there is a possibility that the dedicated pan moves in the horizontal direction. Therefore, it has been decided to provide a receiving part that engages and supports the engaging part of the special pan in the rotary pan receiver for the special pan. The engaging part and the receiving part may be in a relation in which the engaging relation is determined as one. For example, from the viewpoint of regulating the horizontal movement of the dedicated pan described above, the receiving portion that is lowered by one step from the upper edge of the cylindrical rotating pan receiver protrudes inward, and the dedicated pan corresponding to this receiving portion is engaged. What is necessary is just to mount a part from upper direction and to make it engage and to support a special pan on a rotation pan receiver.

  In addition, the dedicated pan provided with such an engaging portion is a pan having a circular arc shape with a part of the spherical surface cut out, and the support portion is effective when the supporting portion is an annular member fitted on the outer surface of the dedicated pan. Here, “a cross-section arc-shaped pan with a part cut off from a spherical surface” means a pan having an outer shape typified by a Chinese wok, and if the shape can be rotated horizontally, Something like that. The engaging portion provided on the outer surface of the dedicated pan may be partially or over the entire outer surface. However, it is preferable that the pan having an arcuate cross-section obtained by cutting off a part of the spherical surface is configured by the annular member so as to maintain the posture by the engaging portion without restricting the direction of the handle.

  Maintaining the attitude of the dedicated pan with respect to the rotating pan receiver results in the advantage that the heating part of the dedicated pan by the heating means can be specified. First, when the heating means is a combustion-type heater housed in a cylindrical rotary pan receiver, heat from the heating means is transferred to the center of the dedicated pan by an induction cylinder provided between the rotary pan receiver and the heating means. Can be guided. Here, the combustion heater means a heating means for heating an object with a flame using gas or oil as a fuel, and a gas stove can be exemplified. In the case where the dedicated pan is a pan having a circular arc shape obtained by cutting off a part of the spherical surface, the portion used for cooking the food is usually near the center. The induction cylinder concentrates the heat from the gas stove, which is a heating means, in the vicinity of the center so as to efficiently use the heat. If it is turned over, the heat transfer to other than the center of the dedicated pan is reduced, and for example, there is an advantage that the rotating pan receiver is not heated.

  When the heating means is an electromagnetic induction heater housed in a cylindrical rotating pan receiver, it is provided on the outer surface of the dedicated pan so that at least the center of the dedicated pan and the electromagnetic heating cooker are at a predetermined distance. The position of the engaging portion may be set. The electromagnetic induction heater is a heating means that heats an object using electromagnetic induction, which is currently known as an IH cooker or an electromagnetic cooker. In this electromagnetic induction heater, it becomes difficult to generate a sufficient eddy current when the dedicated pan moves away. However, in the food cooking device of the present invention, since the dedicated pan rotates, it is not preferable to bring the dedicated pan into contact with the electromagnetic induction heater. Therefore, the distance between the dedicated pan and the electromagnetic induction heater is set to a minimum by a support portion provided on the outer surface of the dedicated pan, and a sufficient eddy current is generated at least in the center of the dedicated pan. When the electromagnetic induction heater has a shape along the outer surface of the dedicated pan, the entire dedicated pan is set to a predetermined distance.

  According to the present invention, it is possible to solve a problem associated with downsizing or automation and to provide a food cooking apparatus that realizes good automatic cooking of food. The food cooking device can be miniaturized by allocating the pan transmission mechanism to the rotating pan receiver and the stirring bar transmission mechanism to the stirrer, respectively, by the effect of using both drive sources. The transmission mechanism for pans suppresses noise even when large rotational power is transmitted to rotate the pan that has become heavier by loading food, by transmitting rotational power by pressing the rotating disk and the annular plate. Can do. This is the effect of calming by the pan transmission mechanism in the present invention.

  The transmission mechanism for the stirrer converts the transmission direction of the rotational power by the meshing output side drive gear and output side driven gear, the stirrer side driven gear and the stirrer side drive gear, and the rotational power is fixed from the drive source by the transmission shaft. The rotation power is transmitted to the stirrer away from the drive source with certainty and a certain distance. Further, by interposing the output-side drive gear and the output-side driven gear, the stirrer-side driven gear, and the stirrer-side drive gear that are in the meshing relationship, if any of the meshing relationships is cancelled, The rotation can be stopped. The gearbox facilitates the operation of releasing the meshing relationship. As described above, the transmission mechanism for the stirrer in the present invention has a function of stopping the stirrer having the same driving source as that of the rotary pan receiver independently from the rotary pan receiver while ensuring the degree of freedom of arrangement of the stirrer. Has the effect of being realized concisely.

  The stirrer in which the main body of the stirrer is elastically supported on the rotation shaft changes the posture or position of the stirrer according to the pan, and realizes proper stirring of food in different pans. In addition, the stirrer in which the rotating shaft and the stirrer are detachable realizes replacement of the stirrer body as necessary. Similarly, the spatula in which the spatula plate is elastically supported on the spatula support part changes the posture or position of the spatula plate according to the pan, and realizes proper gathering of food in different pans. The spatula with the spatula support part and the spatula plate detachable enables the replacement of the spatula as needed, and the spatula support part that can be raised and lowered allows the spatula to be retracted when replacing the pan. To do. These have the effect of improving the cooking of the food by the food cooking apparatus which is being automated, and enabling the stirrer body or the spatula plate to be appropriately washed.

  The configuration in which the special pan provided with a support part on the outer surface is supported by the rotary pan receiver is to maintain the posture of the special pan horizontally in the food cooking device, and to rotate the special pan stably and the stirring bar or spatula. As a result, the heat efficiency of the heating means can be increased, and the food cooking apparatus can be automated and the food can be effectively cooked and the operation cost can be reduced. Thus, the present invention has the effect of enhancing the value as a food cooking device not only by the effect of improvement of each part but also by the synergistic effect of each part by reviewing each part from the viewpoint of miniaturization or automation of the food cooking device. .

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front view showing an example of a food cooking device 1 of the present invention using a combustion heater 11 as a heating means, FIG. 2 is a cross-sectional view of the food cooking device 1 as seen from the right, and FIG. 4 is a rear view of the apparatus 1, FIG. 4 is a plan view of the food cooking apparatus 1 in a state where the special pan 41 is placed on the rotary pan receiver 12, and FIG. 5 shows the stirrer 13 and the spatula 14 with the special pan 41 removed. 6 is a partially enlarged cross-sectional view showing the relationship between the rotary pan receiver 12 and the support roller 121, and FIG. 7 is an enlarged cross-sectional view of the vicinity of the stirrer 13 and the spatula 14; 8 is a cross-sectional view corresponding to FIG. 7 using another stirrer 15, FIG. 9 is a cross-sectional view corresponding to FIG. 7 showing the state where the stirrer 13 and the leading spatula 14 are sprung up according to the gear box 16, and FIG. 13 is a partially broken side view showing a disassembled state of FIG. 13, FIG. 11 is a partially broken side view showing a disassembled state of another stirrer 17, and FIG. 14 is a partially cutaway side view showing a disassembled state of.

  The food cooking device of the present invention can use a combustion type heater or an electromagnetic induction type heater as a heating means, but since there is little difference between the configurations of both, after first explaining the configuration with the combustion type heater 11, Only differences in the case of using the electromagnetic induction heater 31 (see FIGS. 14 and 15 described later) will be described. As shown in FIGS. 1 to 5, the food cooking device 1 of this example is an example in which a gas stove using gas as a fuel is used as the combustion heater 11. A rotating pan receiver 12 that rotates horizontally on the upper surface 181, a combustion heater 11 that is a heating means for the dedicated pan 41 that rotates horizontally on the rotating pan receiver 12, and a stirrer 13 and a closer behind the upper surface 181 The elevator base 161 is provided with a gear box 16 that supports the spatula 14 so as to be movable up and down. The stirring bar 13 and the spatula 14 need only be able to protrude into the dedicated pan 41 supported by the rotary pan receiver 12, and may be provided on the side of the main unit base 18 if there is no inconvenience in handling.

  The main unit base 18 has a cock 111 for adjusting the gas flow rate of the combustion heater 11 protruding from the front surface 182, and an operation or stop button 183, a speed control volume 184, and an emergency stop button 185 of the rotary pan receiver 12. An operation box 186 is provided. Thereby, the food cooking apparatus 1 of this example can operate all processes necessary for automatic cooking of food from the front surface 182 side of the main body base 18. In addition, in order to reduce the size of the food cooking device 1 of this example, the upper surface 181 of the main body base 18 has almost no space other than the rotating pan receiver 12, but for example, left or right of the rotating pan receiver 12 A water supply curan may be provided. Further, a fan that blows air toward the dedicated pan 41 supported by the rotary pan receiver 12 may be installed by the gear box 16, the elevator base 161, or other support unit.

  The rotary pan receiver 12 is a stainless steel cylinder that protrudes from a circular pan receiver opening 187 in which the center of the flat upper surface 181 of the main unit base 18 is cut out. A stainless steel pot receiving guide 188 is provided at the periphery of the pot receiving opening 187. This rotating pan receiver 12 is provided with three receiving portions 122 made of a substantially L-shaped block made of metal at equal intervals in the circumferential direction of the upper edge, and a rotating disk 191 that rotates vertically by an electric motor as a drive source 19 is pressed against it. An annular plate 123 is provided on the lower edge. The dedicated pan 41 is provided with an annular engaging portion 411 on the outer surface, and the engaging portion 411 is placed on the receiving portion 122 of the rotating pan receiver 12 from above, so that the position of the dedicated pan 41 with respect to the rotating pan receiver 12 is A specific horizontal rotation of the special pan 41 while maintaining the above-described posture is realized. An upper support surface 189 is provided inside the main body base 18, and the rotary pan receiver 12 has three annular plates 123 formed by two support rollers 121, 121 provided on the upper support surface 189 and the rotary disk 191. It supports and rotates horizontally by receiving the rotational power transmitted from the rotating disk 191. In this example, the annular plate 123 is provided with a circumferential groove 124. As shown in FIG. 6, each support roller 121 is fitted in the circumferential groove 124 to prevent the position of the rotary pan receiver 12 from being displaced. ing.

  The combustion heater 11 as a heating means is placed on the upper support surface 189 in the rotary pan receiver 12 and is made of stainless steel and concentric with the rotary pan receiver 12 between the rotary pan receiver 12 and the combustion heater 11. A cylindrical guide tube 125 is fixed to the upper support surface 189. The induction cylinder 125 burns toward the outer surface of the dedicated pan 41 supported by the rotary pan receiver 12 while leaving a gap with the upper support surface 189 while ensuring an intake path to the combustion heater 11. Regulates the direction of gas release. Thus, the combustion gas released from the combustion heater 11 can be heated intensively within a certain range from the center of the dedicated pan 41. This is consistent with the range in which the food brought together toward the center of the dedicated pan 41 by the spatula 14 is gathered. In addition, since the induction cylinder 125 is interposed between the combustion heater 11 and the rotary pan receiver 12, heating of the rotary pan receiver 12 by the combustion heater 11 is suppressed, and the rotary pan receiver 12 is excessive. It does not become hot and has a function of reducing the risk of burns to the user.

  As shown in FIG. 7, the stirrer 13 includes a rotating shaft 131 that protrudes from the gear box 16 toward the dedicated pan 41, and a stirrer body 132 that is detachable from the rotating shaft 131. The stirrer main body 132 is engaged with an engagement pin 136 provided on the mounting shaft 135 inserted into the support cylinder 133 in a long hole 134 provided in the support cylinder 133 screwed to the rotating shaft 131. The rotating shaft 131 is connected via the support tube 133. The stirrer main body 132 is made of a metal rod extending in a spiral shape with the mounting shaft 135 as the center, and is stirred while loosening the food in the dedicated pan 41 by rotation according to the rotation shaft 131. As shown in FIG. 8, a stirrer body 152 in which a protrusion 151 is provided on a spiral metal rod may be used for foods that are easily agglomerated. As shown in FIG. 10, the stirrer 13 of this example is provided with a coil spring 137 serving as an elastic support part on the mounting shaft 135 of the stirrer main body 132, and the shape of the dedicated pan 41 is changed. The movement of the stirrer body 132 in the direction perpendicular to the axis due to the difference in amount or type, for example, twisting or tilting, is absorbed by swinging the stirrer body 132 by the deformation of the coil spring 137. As seen in FIG. 11, the stirrer body 175 may be attached to the support cylinder 171 with a coil spring 174 interposed between the push plate 172 and the rotating shaft 173 in the support cylinder 171.

  As shown in FIG. 7, the shifting spatula 14 includes a spatula support portion 141 suspended from a handle base portion 162 protruding forward from the gear box 16, and a spatula plate 142 detachably attached to the spatula support portion 141. The spatula plate 142 is provided with an engagement pin 144 on a mounting shaft 143 to be inserted into the spatula support portion 141, and the engagement pin 144 is engaged with a folded long hole 145 provided in the spatula support portion 141. Connected to the spatula support 141. Because the spatula 14 has the purpose of urging the food to prevent the food from burning on the dedicated pan 41, the spatula plate 142 may have an outer shape having a copying periphery along the inner surface of the dedicated pan 41. Further, since the spatula 14 is intended to gather around the food in the rotating special pan 41, the spatula plate 142 is displaced from the radial direction of the special pan 41. It is preferable that the center side of the plate be inclined downstream in the rotation direction of the dedicated pan 41 (see FIG. 4). As shown in FIG. 12, the shifting spatula 14 of this example incorporates a coil spring 148 serving as an elastic support portion between the push plate 146 and the screw lid 147 in the spatula support portion 141, and the dedicated pan 41 The spatula plate 142 is moved up and down by the compression or extension of the coil spring 148 to absorb the movement in the axial direction of the spatula plate 142 due to the change in shape or the amount or type of food.

  The gear box 16 is a stainless steel cylinder lying perpendicular to the direction in which the stirrer 13 and the spatula 14 are moved up and down, and is supported by a lifting shaft 168 provided at a position offset from the central axis of the cylinder with respect to the elevator base 161. I wear it. The gear box 16 moves up and down as if it is flipped upward as shown in FIG. 9, by operating a handle 163 (see FIG. 1) that protrudes leftward from a handle base 162 provided with a spatula support 141. It is free. The gear box 16 is open on the lower surface side, and a transmission shaft 192 extending upward from the inside of the main body base 18 is projected, and a stirrer side drive gear 193 fixed to the upper end of the transmission shaft 192 is connected to the gear box 16. Is engaged with a stirrer-side driven gear 194 fixed to a rotating shaft 131 attached to the shaft. The handle 163 is provided with a lever 164 for operating a moderation mechanism for connecting and releasing the stirrer transmission mechanism. The moderation mechanism of this example includes a protrusion 165 that can be moved in and out from the elevator base 161 toward the gear box 16, and switching holes 166 and 167 into which the protrusion 165 fits in the connection position and the release position, respectively. When the lever 164 provided on the handle 163 is grasped, the protrusion 165 of the elevator base 161 is retracted into the elevator base 161 and is disengaged from the connection position switching hole 166, so that the gear box 16 can be freely raised. When the lever 164 is released while the projection 165 and the release position switching hole 167 coincide with each other, the projection 165 fits into the release position switching hole 167, and the gear box 16 is held in the posture of being flipped up. To do. Thus, the moderation mechanism is a means for holding the position or posture of the raised gear box 16.

  The food cooking device 1 of this example transmits rotational power from the electric motor, which is a drive source 19 fixed to the lower surface of the upper support surface 189 provided inside the main body base 18, to the rotary pan receiver 12 by the pan transmission mechanism. Rotational power is transmitted to the stirrer 13 by the stirrer transmission mechanism. Since the rotational power is transmitted from the single drive source 19 to the rotary pan receiver 12 and the stirrer 13 by separate transmission mechanisms, the rotation of the rotary pan receiver 12 and the stirrer 13 is similarly maintained with a fixed relationship. Increase or decrease. That is, if the rotary pan receiver 12 becomes low speed, the rotation of the stirring bar 13 also becomes low speed, and if the rotation of the rotary pot holder 12 becomes high speed, the rotation of the stir bar 13 becomes high speed. From now on, in the food cooking device 1 of this example, the output itself of the electric motor as the drive source 19 is adjusted by the speed control volume 184 of the operation box 186 provided on the front surface 182 of the main body base 18 as described above, and the rotary pan The rotation of the receiver 12 and the stirring bar 13 is controlled integrally.

  As shown in FIG. 2, the pan transmission mechanism includes a rotating disk 191 that is fixed to the output shaft 195 of the driving source 19 and rotates vertically, and an annular plate 123 that is provided below the rotating pot receiver 12 and rotates horizontally. The rotary disc 191 is pressed against the annular plate 123, whereby rotational power is transmitted through the output shaft 195, the rotary disc 191 and the annular plate 123, and the rotary pan receiver 12 is rotated horizontally. Here, if the rotating disk 191 is made of resin, the friction with the annular plate 123 made of metal or resin increases, so that rotational power can be transmitted without slipping, and noise due to gear meshing etc. is not generated. Has the advantage of The rotational speed of the rotary pan receiver 12 is determined by (radius of the rotating disk 191) / (radius of the annular plate 123) × (rotational speed of the output shaft 195 of the drive source 19).

  As shown in FIGS. 2 and 7, the stirrer transmission mechanism is fixed to the output shaft 195 of the drive source 19 and rotates, and to the rotation shaft 131 of the stirrer 13 and rotates. And a transmission shaft 182 that fixes the output side driven gear 197 and the stirrer side drive gear 193 to each other. In this example, since the transmission direction of the rotational power is changed from the output shaft 195 of the drive source 19 to the rotary shaft 131, the gears 193, 194, 196, 197 are all bevel gears, and the gears 193, 194, 196, 197 are engaged. In combination, the rotational power is transmitted while changing the transmission direction of the rotational power. That is, the output side driven gear 197 of the transmission shaft 192 meshes with the output side driving gear 196 fixed to the output shaft 195 of the driving source 19, and the upper end of the transmission shaft 192 extends through the elevator base 161 into the gear box 16. The stirrer-side drive gear 193 is fixed to the stirrer-side drive gear 193, and the stirrer-side drive gear 193 is meshed with the stirrer-side driven gear 194 of the rotary shaft 131 that is pivotally attached to the gear box 16.

  When the gear box 16 is lowered, that is, when the protrusion 165 of the moderation mechanism is engaged with the connection position switching hole 166, the output shaft 195, the output side drive gear 196, the output side driven gear 197, and the transmission shaft 192 Rotational power is transmitted to the stirrer body 132 through the stirrer side drive gear 193, the stirrer side driven gear 194, and the rotating shaft 131. The rotational speed of the stirrer 13 is decelerated from the rotational speed of the output shaft 195 of the drive source 19 according to the reduction ratio by the combination of the gears 193, 194, 196, and 197. When the gear box 16 is flipped up, that is, when the protrusion 165 of the moderation mechanism is engaged with the release position switching hole 167, as shown in FIG. 9, the stirrer side drive gear 193 and the stirrer As a result of the separation from the side driven gear 194 and the transmission of rotational power, the rotation of the stirrer body 132 can be stopped.

  If the stirrer is disconnected by a part of the stirrer transmission mechanism, the stirrer can stop rotating. From this point, for example, as shown in FIG. 13, a transmission mechanism for a stirrer can be configured using a transmission belt 212 as a transmission member for transmitting rotational power from the output shaft 211 of the drive source 21 to the rotary shaft 131. In the transmission mechanism for the stirrer composed of the transmission belt 212, the transmission belt 212 is wound around an output pulley 213 fixed to the output shaft 211 and an input pulley 215 fixed to the stirrer side drive gear 214. Since the stirrer 13 is inclined toward the dedicated pan 41, the output shaft 211 of the drive source 21 and the rotating shaft 131 of the stirrer 13 do not coincide with each other. The direction change pulleys 216 and 217 are addressed to the belt 212. As described above, the transmission mechanism for the stirrer including the transmission belt 212 has an advantage that the rotational power can be transmitted from the drive source 21 in any direction.

  FIG. 14 is a front view showing an example of the food cooking device 3 of the present invention using the electromagnetic induction heater 31 as a heating means, and FIG. 15 is a sectional view of the food cooking device 3 as seen from the right side. Although the food cooking apparatus of this invention can be comprised regardless of the kind of heating means, the structural difference by a heating means exists. Below, the food cooking apparatus 3 using the electromagnetic induction heater 31 as a heating means will be described focusing on the differences from the food cooking apparatus 1 using the combustion heater 11 as described above as a heating means.

  As shown in FIGS. 13 and 14, the food cooking device 3 of this example has a rotating pan receiver 12 that rotates horizontally on an upper surface 181 of a stainless steel main body base 18 that is substantially square in plan view, and the rotating pan receiver 12. An electromagnetic induction heater 31 that is a heating means of the dedicated pan 51 that rotates horizontally on the elevator, and an elevator base 161 that is attached to a gear box 16 that supports the stirrer 13 and the spatula 14 at the rear of the upper surface 181 so as to be movable up and down. And the control tower 32 provided with the touch panel 321 is provided.

  The control tower 32 sets the heat amount and operation time of the electromagnetic induction heater 31 and sets the rotation speed and rotation time of the rotary pan receiver 12 through the touch panel 321. An operation menu combining the setting of the electromagnetic induction heater and the setting of the rotary pan receiver 12 is created in advance, and these operation menus are displayed on the touch panel 321 and can be selected by the user. Thus, the control tower 32 is provided with an end lamp 322 and a buzzer 323 for notifying the end of the operation menu. In addition, the control tower 32 is provided with a power button 324 and an emergency stop button 325 as a food cooking device independently of the touch panel 321. The food cooking device 3 of this example is necessary for automatic cooking of food. Processing can be set and executed automatically. Even in the food cooking device 1 (see FIG. 1) using the combustion heater 11 described above, for example, by using a proportional valve that can be electrically operated instead of the cock 111, the same processing setting and automatic processing as in this example can be performed. Can be executed.

  The configuration and support mode of the rotary pan receiver 12 are the same as those of the food cooking device 1 illustrated above. Since the electromagnetic induction heater 31 is used as the heating means, there is no need to concentrate the fuel gas and there is no induction cylinder. Specifically, an electromagnetic induction heater 31 having a surface following the outer surface of the dedicated pan 51 is disposed in the rotary pan receiver 12. The electromagnetic induction heater 31 does not need to secure an intake path, but is heated by energization, and therefore has a cooling fan 311 attached to the bottom surface. In addition, the inverter 312 for supplying power to the coil used for the electromagnetic induction heater 31 is arranged on the middle support surface 313, and the control unit 314 of the electromagnetic induction heater 31 and the touch panel 321 is arranged on the lower support surface 315, respectively. doing.

  An annular engagement portion 511 provided on the outer surface of the dedicated pan 51 is placed on the receiving portion 122 provided on the upper edge of the rotary pan receiver 12 from above so that the horizontal orientation of the dedicated pan 51 is maintained and rotated horizontally. Is the same as the food cooking apparatus 1 illustrated above. In this example, the receiving part 122 and the engaging part 511 have a function of setting the distance between the outer surface of the dedicated pan 51 and the surface of the electromagnetic induction heater 31 by making the positional relationship between them appropriate. doing. From the above, in the above-described example using the combustion heater 11, it is only necessary to maintain the horizontal posture of the dedicated pan 41. Therefore, the same engaging portion 411 can be used even if the original pan changes. However, in the example using the electromagnetic induction heater 31, in order to appropriately set the distance between the surface of the electromagnetic induction heater 31 and the outer surface of the dedicated pan 51, when using an original pan having a different external shape, It is necessary to use an appropriate engaging portion 511.

  As described above, the food cooking device 3 using the electromagnetic induction heater 31 as a heating means has a slightly different relationship between the rotary pan receiver 12 and the dedicated pan 51, but the other configuration is the above-described combustion heater 11. There is no difference from the food cooking device 1 using as a heating means. For this reason, the stop of the stirrer 14 by lifting the stirrer 13, the spatula 14 and the gear box 16 is not different from the above-described example, and the description thereof is omitted here. This means that the stirrer 13 and the spatula 14 can be shared by a plurality of food cooking devices 1 and 3 regardless of the heating means. If the original pan has the same external shape, it can be shared up to the dedicated pans 41 and 51. Then, it means that the food cooking devices 1 and 3 have applicability of members.
