[0001]
TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an automatic gyoza baking machine for automatically baking gyoza and a gyoza cooking method.
[0002]
[Prior art]
In general, when cooking gyoza, as shown in FIG. 9, a round or square grill pan 1 having a flat bottom surface is heated by a gas stove 2 or a heater, and is placed on a flat portion 3 of the grill pan 1 before cooking. The dumplings 4 are arranged in a line, and the amount of water 5 or hot water at which half the height of the dumplings 4 is immersed is added, the lid 6 is covered, the water 5 is boiled, and the dumplings 4 are boiled for 2-3 minutes. In this step, since the inside of the fryer 1 is sealed by the lid 6, the boiling steam is filled in the fryer 1, and the steam also steams the exposed portion of the gyoza 4. Next, the lid 6 is opened, the remaining hot water is discarded, the lid 6 is again closed, the grill pan 1 is heated, the bottom of the dumpling 4 is grilled, and heat is sufficiently penetrated to the inside of the dumpling 4. Do this for a few minutes to complete the cooking. Then, the lid 6 is opened, the baked gyoza 4 is taken out, and is put on a plate. Such a method of cooking the gyoza 4 is performed almost unchanged regardless of whether it is a frozen gyoza or a raw gyoza.
[0003]
As described above, the amount of the water 5 to be initially put into the baking pan 1 is often set to such an amount that the gyoza 4 is half-soaked, but is extremely large so that the amount of the water 5 evaporates in a few minutes. There are also cooking methods to reduce it. In this case, there is no need to discard the remaining hot water, and cooking proceeds continuously up to the baking process. However, in this method, the ears of the gyoza 4 at the time of completion of cooking become firmer and taste better than when boiling. Inferior. Therefore, although it takes time to discard the hot water remaining on the way, many of the cooking methods described above, in which the gyoza is boiled first, are employed.
[0004]
As an example of a commercial gyoza grilling machine, one described in Patent Document 1 is known. The structure is such that the fryer and the rear end of the lid are separately hinged to the main body case so that it can be raised and lowered, and when the lid is opened and the fryer is disciplined, the internal hot water flows out from the rear end of the fryer. That's what we do. As a cooking method, gyoza was lined up while keeping the grill pan horizontal, boiling about half of the water, and the remaining hot water was lifted and tilted and provided on the back of the main case Drain the water into Toyo. Then, the pan is returned to a horizontal position and further baked to complete the cooking.
[0005]
In such a cooking method, the dumpling fryer is for business use, and therefore, a certain amount of water is poured into the fryer and cooking time is controlled by timer control. However, the lifting operation of the pan to drain the water in the pan during the intermediate process of cooking is performed manually.
[0006]
Next, there is a gyoza fryer having a structure that can be cooked without raising and lowering the fryer, as described in Patent Document 2. In this structure, an opening for drainage is formed at the bottom of the dumpling pot, and a water return member that opens and closes the opening by sliding on a planar bottom surface is provided. Then, the dumplings are arranged in a dumpling pan with the opening closed by a water return member, and water is put into the dumplings for boiling. When the boiling process is completed, the water return member is slid to open the opening to drain the water. Thereby, drainage can be performed only by the horizontal operation of the water return member.
[0007]
Further, an example of a conventional commercial gyoza fryer is shown in Patent Document 3. In this structure, a drain pipe is provided in a flat part of a baking pan, and a valve which is manually opened and closed is provided in the opening of the drain pipe. Thereby, when it is necessary to drain the water inside the pan during cooking, the valve is opened.

[Problems to be solved by the invention]
In general, the thickness of the flat part of the baking pan of a commercial dumpling fryer is as thick as 8 to 12 mm for the purpose of maintaining the uniformity of the temperature of the flat part and increasing the heat storage property of heat, There is considerable weight. The technique described in Patent Literature 1 requires a great deal of labor to manually lift such a heavy pan. Further, at the time of return, there is a risk of rapid return due to the weight of the grill pan, and there is also a problem that the structure in which a spring damper for return must be provided to prevent this risk is complicated. In addition, although water injection can be performed automatically, there is a problem that a time for raising the temperature of the injected water to hot water of a predetermined temperature is required, and the cooking time cannot be reduced. Furthermore, if the heat source is a gas burner, there is a danger of burns when the gas burner is burning when the pot is lifted. There is also a problem that it involves a troublesome operation of stopping the gas only and re-igniting for the next step.
[0010]
Next, the one described in Patent Literature 2 does not have sufficient watertightness due to the water return member, and easily leaks water from a gap, and is not actually commercialized.
[0011]
Further, the one described in Patent Document 3 is inferior in operability because the opening and closing of the valve is manual, and an O-ring is used for the valve in order to improve watertightness. Is provided on the flat part of the baking pan at 250 ° C., which is considered to deteriorate in a short time. For this reason, there is a problem that the life of a valve provided at a place for discharging food stains, oil, salt, and the like at high temperatures as well as hot water is short.
[0012]
The present invention is intended to automatically perform drainage work during cooking of dumplings, eliminates the need for manual labor during cooking, and eliminates the danger of lifting the pan so as to tilt it. It is intended to provide an automatic cooker.

[0032]
Therefore, it is possible to achieve energy saving by reducing power consumption and reduce environmental load.
[0033]
BEST MODE FOR CARRYING OUT THE INVENTION
A first embodiment of the present invention will be described with reference to FIGS. First, a rectangular parallelepiped main body case 7 is provided, and the main body case 7 is supported by support legs 8 provided at four corners. An electric control unit 9 is provided inside the main body case 7 on the front side, and a sealed hot water tank 10 is provided at the center. A heater 11 with a thermostat is disposed inside the hot water tank 10, and a water supply pipe 13 connected to a water supply unit such as a water supply via a water supply electromagnetic valve 12 is connected to a lower side surface. ing. Further, a drain valve electromagnet 14 is disposed at the rear of the hot water tank 10 as drain valve driving means. The heater 11 only needs to have a function of heating water in the hot water tank 10, and may be provided on a side wall or the like, and need not necessarily be built in the hot water tank 10.
[0034]
The electric control unit 9 has a function of program control in which a two-stage temperature control circuit and several stages of a timer circuit are combined in order to automatically cook. It can also be called a control device.
[0035]
A body case deck 15 is provided on the upper part of the body case 7, and a baking pan 17 having a flat bottom 16 is horizontally fixedly attached to the center of the body case deck 15. A sheath heater 18 serving as a heating element is fixed to the lower surface of the baking pan 17, and a lower portion of the sheath heater 18 is covered with a heat insulating material 19. An end of the sheathed heater 18 protrudes downward and is connected to an electrical connection (not shown). Behind the flat part 16 of the baking pan 17, a drain valve seat 20 having a diameter of 40 mm is formed just above the drain valve electromagnet 14, and the drain valve seat 20 is inclined obliquely downward. It is connected to a drain pipe 21 having an end protruding outside the main body case 7. An end opening of the drain pipe 21 is communicated with a drain receiving tank 22 disposed outside the rear of the main body case 7. Although the drain pipe 21 has a slope of about 45 degrees, the reason why the drain pipe 21 has a slope of about 45 degrees in spite of manufacturing difficulty is that the fluid to be discharged is gyoza. This is a broth after boiled.The dumplings are covered with powdered flour so that they do not stick to each other, and the starchy material melts out in the process of boiling and becomes a thin paste. This is to ensure that they are discharged without delay. In addition, it is assumed that the scraps from the burnt scraps that have stuck with the scraper after the flat portion 16 of the baking pan 17 has been cooked are pushed in, so that some solids are discharged together. The reason why the diameter of the drain valve seat 20 is set to be as large as 40 mm together with the drain pipe 21 is to make it difficult for the drain pipe 21 to be clogged and to facilitate cleaning when it is clogged.
[0036]
Next, a valve 24 is provided at the upper end of the connecting rod 23 connected to the drain electromagnet 14 so as to come into contact with and separate from the drain valve seat 20, and a drain valve 25 is formed by the valve 24 and the drain valve seat 20. It is configured. The valve body 24 is urged upward together with the connecting rod 23 by a spring 26, and maintains the drain valve 25 in an open state when the drain electromagnet 14 is not energized.
[0037]
Next, a pot lid 28 hinged to the rear end of the main body case deck 15 via a support shaft 27 is rotatably attached. The pot lid 28 is at least partially made of a magnetic material, and a protruding portion 29 at the tip is made of a magnetic material. The protruding portion 29 faces a lid attracting electromagnet 30 provided inside the main body case 7. When the lid attracting electromagnet 30 is energized, the pan lid 28 is maintained in a closed state so as to seal the grill pan 17. The pot lid 28 is constantly urged in the opening direction by an opening spring 31. When the lid attracting electromagnet 30 is not energized, the attraction force to the protrusion 29 is released, and the pot lid 28 is released. It is opened automatically.
[0038]
An inner lid 33 for sealing the upper surface of the baking pan 17 is fixed to a bottom surface of the pan lid 28 via a coupling plate 32. A water jet nozzle 34 is provided below the coupling plate 32 for fixing the inner lid 33. Further, the shaft portion 35 that rotatably holds the coupling plate 32 is a pipe shaft that also serves as a water supply path while forming a water path with a pipe 35 ′. This pipe shaft is connected to a support shaft 27 that supports the pot lid 28, and the support shaft 27 is a pipe shaft that also serves as a water supply path similarly to the shaft portion 35, and It is configured to be rotatable around the support shaft 27. The support shaft 27 formed by the pipe shaft communicates with the uppermost portion of the hot water tank 10 via a connection pipe 36.
[0039]
A magnet 37 is attached to the rear end of the pot lid 28, and the main case 7 is connected to the electric control unit 9 at a position where the magnet 37 of the pot lid 28 in a closed state faces. A magnetically responsive switch 38 for sending a signal indicating whether the pan lid 28 is open or closed is fixed. The magnet 37 serves as detecting means for detecting the open / closed state of the pot lid 28.
[0040]
In addition, 39 is gyoza and 40 is water for cooking. Reference numeral 41 denotes a handle for manually moving the pot lid 28 in the closing direction.
[0041]
FIG. 3 is a plan view showing the entire arrangement of the grill pans 17, and two grill pans 17 are arranged on the left and right sides of the main body case 7. The lower side in FIG. 3 is the near side where the cook is located, and the drain valve 25 is located on the far side. Further, the dumplings 39 are arranged in two rows of 12 in one row for one baking pan 17.
[0042]
FIG. 4 shows the cross-sectional shape of the baking pan 17, wherein the flat portion 16 is actually formed in a V-shape with a gentle angle so that the central portion is the lowest, so that the drainage speed can be increased. It is taken into consideration. This shape is to increase the drain speed when draining the water 40 from the drain valve 25 during cooking. Alternatively, the front surface may be raised by only 2 mm so as to be inclined.
[0043]
In such a configuration, when a power switch is first turned on in a state of starting to use, energization of a sheath heater 18 for heating the pan 17 is started, and a digital temperature controller of the pan 17 not shown Since the temperature is set to 150 ° C., the baking pan 17 is heated to a temperature of 150 ° C. and is in a standby state. The hot water tank 10 is filled with water 40 via a water supply electromagnetic valve 12, and the water temperature is controlled by a heater 11 with a thermostat so that it is always maintained at about 95 ° C. I have.
[0044]
The progress of cooking will be described below based on the timing chart shown in FIG. First, at the start of cooking, as shown in FIG. 2, the dumplings 39 are arranged in the baking pan 17 with the pot lid 28 opened, as shown in FIG. 3, and then as shown in FIG. Then, the pot lid 28 is closed. As a result, the magnet 37 provided near the support shaft 27 approaches the magnetically responsive switch 38, and the signal from the magnetically responsive switch 38 indicates that a signal to start cooking has been generated.
[0045]
Upon receiving the cooking start signal in this manner, the electric control unit 9 first energizes the lid attracting electromagnet 30 to attract the protrusion 29 and hold the pot lid 28 so as not to open. This holding time is the time T until the cooking is completed. ₁ And is set to 4 minutes and 30 seconds. A few seconds after the lid 28 is closed, the water supply solenoid valve 12 ₂ Open about 10 seconds of the setting time set by the timer, push out the hot water of 95 ° C. stored in the hot water tank 10, and release about 600 cc of hot water for boiling the dumpling 39 into the baking pan 17 from the water jet nozzle 34. I do. At this time, the temperature of the baking pan 17 was kept at 150 ° C., but it is not low-temperature water but 95 ° C. boiling water, so that the poured boiling water immediately boils. It will be in a state and the gyoza 39 will be boiled. This boiling time is T ₃ It is set to about 2 minutes by a timer.
[0046]
T ₃ After about 2 minutes set by the timer, the drain valve 25 is opened and the boiling water remaining in the baking pan 17 is discharged from the drain pipe 21 to the drain receiving tank 22 through the drain valve 25. The time at this time is about 5 seconds. When the hot water boiling the gyoza 29 is drained and disappears, the temperature of the baking pan 17 rises rapidly, is heated to the set temperature of 210 ° C., and automatically shifts to the baking cooking process. Then, when 4 minutes and 30 seconds have elapsed from the total cooking time, the energization to the lid adsorption electromagnet 30 is cut off, the pot lid 28 is opened and opened by the force of the spring 31 to the position shown in FIG. At the same time, the energization of the sheath heater 18 is controlled such that the temperature of the pan 17 becomes 150 ° C.
[0047]
Total cooking time T ₁ Is the cooking time for closing the pot lid 28, starting cooking, and boiling the gyoza 39. ₂ Timer time (T ₂ The time is also the time during which the drain valve 25 is closed) and the time when the gyoza 39 is baked. This total cooking time T ₁ Is set to about 4 minutes and 30 seconds when the gyoza 39 has a standard size (25 g per piece).
[0048]
The fact that the water supply temperature for boiling in the hot water tank 10 is set to 95 ° C. immediately before boiling is equivalent to the total cooking time T ₁ It is very useful for shortening. Conventionally, water was hand-injected or a certain amount of tap water was injected by timer control of a solenoid valve, but in this method, for example, the grill was previously heated to about 200 ° C. However, if a large amount of water (about 600 to 1000 cc) is poured for boiling, the temperature of the pan falls rapidly, and one to two minutes elapse before the boiling operation, and the total cooking time T ₁ Requires 6 minutes. Therefore, pouring hot water set at 95 ° C. immediately before boiling is equivalent to the total cooking time T ₁ Is effectively shortened.
[0049]
In addition, the fact that the temperature of the pan 17 is set to 150 ° C. before cooking is combined with the above-described supply of hot water, and the total cooking time T ₁ Is greatly shortened. The order of the dumplings 39 is not known when it will be placed, and if an order is placed, it must be cooked and served as soon as possible. If the temperature of the baking pan 17 is room temperature during the waiting time until an order is placed, it takes a few minutes to heat it to 150 ° C. or more and 200 ° C. or so. On the other hand, keeping the temperature of the pan 17 at 200 ° C. during the waiting time until an order is placed wastes heating energy, which is not good for the working environment.
[0050]
For this reason, in the present embodiment, the hot water in the hot water tank 10 is always maintained at 95 ° C., and an amount of 1000 cc is stored and 600 cc of hot water is discharged from the water jet nozzle 34 to the baking pan 17 each time. So consider In addition, since the temperature of the roasting pan 17 is set to 150 ° C. at the start of cooking and hot water of 95 ° C. is released, even if the dumplings 39 at room temperature or frozen are lined up, almost immediately a boiling state is reached. The simmering work will start. Also, the heating energy for keeping the temperature of the pan 17 at 150 ° C. during standby is about half that of keeping it at 200 ° C., the energy saving effect is great, and the heat dissipation to the working environment is reduced by half. Can be improved.
[0051]
The temperature setting of the baking pan 17 is set to 150 ° C. during standby (before cooking), but the temperature setting is switched to 210 ° C. at the same time as the pot lid 28 is closed to start cooking. The setting of 210 ° C. is performed until the cooking is completed, that is, the total cooking time T ₁ Is continued during the time that elapses, and at the same time as the cooking is completed, the temperature returns to the standby 150 ° C. temperature setting.
[0052]
As described above, the temperature of the fryer 17 is set during cooking. ₁ The time is 210 ° C., otherwise 150 ° C., but when cooking is started, that is, when the lid 28 is closed, hot water of about 95 ° C. is discharged onto the fryer 17 after a few seconds. Drops to near the boiling temperature of water. On the other hand, when the set temperature of the fryer 17 is changed to 210 ° C., the sheath heater 18 of the fryer 17 is kept energized and heated, so that about 600 cc of water 40 boils and the gyoza 39 is boiled. To the dumplings 39, the remaining heat evaporates into steam, and the exposed portion of the dumplings 39 is steamed. The excess steam is released into the atmosphere from the gap between the pot lid 28. You.
[0053]
Since the drain valve 25 is closed for about two minutes from the start of cooking, the above-described step of boiling the dumplings 39 is performed. However, after two minutes, the power supply to the drain valve electromagnet 14 is interrupted, and the force of the spring 26 is reduced. Thus, the drain valve 25 is opened and drained. On the other hand, since the temperature setting of the pan 17 is 210 ° C., the sheath heater 18 is continuously energized, and the temperature of the pan 17 reaches 210 ° C. in about 2 minutes. The contact surface between 39 and the pan 17 rises while being heated to 100 ° C. or higher, rises to 210 ° C. after 2 minutes, and after 30 seconds, the total cooking time T ₁ , The pot lid 28 is automatically opened and the cooking is completed.
[0054]
In this way, the boiling water discharged onto the pan 17 is simmered for 2 minutes before being drained, and after the drainage, the temperature setting of the pan 17 is unchanged at 210 ° C. When the water is drained, the baking process is automatically performed, and a good baking is performed to complete the cooking.
[0055]
Next, the grill pan 17 used in the present embodiment will be compared with a conventional grill pan. In general, as a material for a baking pan, an iron plate is often used because it has good compatibility with oil. Conventionally, a thick plate having a thickness of 8 to 12 mm is often used in order to maintain temperature uniformity. That is, if the baking pan is heated to the highest possible temperature (200 to 250 ° C.) before starting cooking by thickening the plate, even if a large amount of water is poured at the same time as the start of cooking, 70 ° C. The temperature reaches ~ 80 ° C, and after 30 seconds to 1 minute, it is brought into a boiling state and the purpose of boiling gyoza can be achieved.
[0056]
However, in the apparatus having the structure shown in Patent Literature 1, the temperature of the pan 1 when the pan 1 is inclined backward and drained is reduced to 100 to 120 ° C. After the gyoza 4 is boiled, it is necessary to rapidly heat the temperature of the fryer 1 again to 200 ° C. or higher in order to bake it. When the capacity of the electric heater is fixed, the temperature rise at the start of heating becomes slower as the plate thickness of the baking pan 1 is larger. Therefore, when the plate thickness of the baking pan 1 is large, it is necessary to increase the size of the heat source to be heated.
[0057]
In the present embodiment, the plate thickness of the baking pan 17 is 2.9 mm, which is easy to manufacture and can maintain moderate temperature distribution uniformity. Since the plate thickness is thin, the capacity of the sheathed heater 18 is about half the capacity of the thick plate, the temperature of the pan 17 rises rapidly, and the gyoza 39 is baked after being boiled. This can shorten the time of the process. Even if the baking time after draining the broth is set to 2.5 minutes, the temperature rises from 100 to 120 ° C. to 210 ° C. in about 2 minutes, and the ON / OFF of the sheath heater 18 is performed for 30 seconds thereafter. Sufficient baking is performed while maintaining 210 ° C. by the OFF control. In particular, by combining the method of keeping the temperature of the hot water to be injected at 95 ° C. and controlling the temperature of the baking pan 17 to about 150 ° C. during standby, the hot water of 95 ° C. is almost at the same time as the start of cooking. Since the water is poured into the baking pan 17 at about 150 ° C., the process of immediately reaching the boiling temperature and boiling the gyoza 39 is started simultaneously with the start of cooking.
[0058]
Further, in the present embodiment, even if the pan 17 is a thin plate, the sheathed heater 18 is provided in close contact with the lower surface of the pan 17 and the outside thereof is covered with a heat insulating material 19, so that the temperature can be reduced. The uniformity of the distribution is maintained. In addition, even if the power consumption is smaller than that of the conventional thick plate (actually, 3 kW is reduced to 2 kW), there is an effect that the rising temperature of the baking rises quickly.
[0059]
The hot water tank 10 has a capacity of about 1000 cc, and is controlled to 95 ° C. by a thermostat with a heater 11 of 0.8 kW. Gyoza 39 total cooking time T ₁ Is 4 minutes and 30 seconds, when the amount of water injected per time is 600 cc, for example, tap water at 10 ° C. can be heated to 95 ° C. within 4 minutes and 30 seconds. That is enough, a capacity of 0.8 kW is sufficiently possible.
[0060]
As described above, in the present embodiment, the capacity of the sheathed heater 18 for heating the baking pan 17 could be reduced from 3 kW for a conventional thick plate to 2 kW. However, as described above, the heater 11 of 0.8 kW is used for heating the hot water tank 10, and the total is 2.8 kW for one baking pan 17, which is 3 kW for the conventional thick plate. It does not seem to change much, but in fact, the total cooking time T ₁ Has been reduced by one and a half minutes, and the temperature of the pan 17 that had to be heated to 210 ° C. during standby can be reduced to 150 ° C. This makes it possible to reduce heat radiation to the surroundings during standby, thereby contributing to energy saving and reducing the environmental load.
[0061]
Next, the manufacturing advantages of the baking pan 17 will be described. In the case of a conventional plate having a large plate thickness, that is, a plate having a thickness of more than 5 mm, a welded structure is required to integrate the side portion, which may be about 3 mm, with the bottom portion having a thickness of 5 mm or more. There's a problem. On the other hand, since the baking pan 17 in the present embodiment may be a thin plate, the whole can be manufactured in a folded structure. In this case, it is necessary to weld only the four corners of the side portion, but it is inexpensive because the welding length may be short. Also, in the case of a thin plate and mass production is required, it is possible to obtain a low-cost, good-looking, excellent-durability product without welding work by press working. It can be easily manufactured even if it has a V-shape in which the central portion is depressed to promote it.
[0062]
In addition, the standby temperature of the grill pan during standby, the set temperature of the grill pan after the start of cooking, the time of the simmering process, the time of the baking process, the water temperature in the boiling water tank, The plate thickness and the like are shown as preferable numerical values, and are not limited to these numerical values in practice.
[0063]
A second embodiment of the present invention will be described with reference to FIGS. The same parts as those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. First, a drain port 42 having a diameter of 40 mm is formed behind the flat portion 16 of the grill pan 17. The drain port 42 has an upper edge formed as a drain valve seat 43. The drain valve seat 43 is connected to a drain pipe 44 having an end protruding outside the main body case 7. Regarding the shape of the drain pipe 44, similar to the above-described first embodiment, it is difficult to manufacture, but it may be made to protrude to the outside with an inclination of about 45 degrees. Due to this, the fluid to be discharged is the broth after boiling the gyoza, and the gyoza is coated with flour on the surface so that they do not stick together, and the starchy material melts out in the process of boiling and becomes a thin paste Therefore, such a fluid can be discharged without delay. In addition, it is assumed that after scraping the flat portion 16 of the baking pan 17, scraps that have been stuck with a scraper and that have been peeled off are pushed in, so that some solids can be discharged together. Further, the diameter of the drain valve seat 43 is set to be as large as 40 mm together with the drain pipe 44, so that the drain pipe 44 is hardly clogged, and cleaning when clogged is facilitated.
[0064]

A valve body 47 that comes in contact with and separates from the body is provided, and the valve body 47 and the drain valve seat 43 constitute a drain valve 48. The connecting rod 46 has a function of a magnetic attraction of an electromagnet. The valve body 47 is urged downward together with the connecting rod 46 by a spring 49, and closes the drain valve 25 when the drain valve electromagnet 45 is not energized with the pan cover 28 closed. When the drain valve electromagnet 45 is energized, the drain valve 25 is opened.
[0065]
In such a configuration, the preparation for cooking the dumplings 39 and the progress of the cooking are the same as those in the first embodiment described above, and a description thereof will be omitted, but in the present embodiment, the pot lid 28 When the pan lid 28 is closed, the valve body 47 closes the discharge valve seat 43 by the pressing force of the spring 49 because the drain valve electromagnet 45 is not energized in the state in which is opened.
[0066]
In this state, the hot water stored in the hot water tank 10 is supplied, and the gyoza 39 is boiled, and T ₃ When about 2 minutes set by the timer elapse, the discharge valve electromagnet 45 is energized. As a result, as shown in FIG. 7, the connecting rod 46 and the valve body 47 rise and separate from the discharge valve seat 43, open the discharge port 42, and remove the boiling water remaining in the baking pan 17 through the discharge pipe 44. To the outside. Thereafter, the process automatically shifts to the baking process. Then, when the entire cooking time has elapsed after the completion of the baking cooking process, the power supply to the lid adsorption electromagnet 30 is cut off, the pot lid 28 is opened, and the pot 31 is opened to the position shown in FIG. I do. At the same time, the energization of the sheath heater 18 is controlled so that the temperature of the baking pan 17 becomes 150 ° C., and the energization of the discharge valve electromagnet 45 is also cut off. Move to
[0067]
Cooking is performed in this manner, but in the case of the present embodiment, since the valve element 47 comes into contact with and separates from the drain valve seat 43 from above, the rubber O There is no need to provide a ring or the like, and there is no risk of water leakage due to deterioration. In particular, since the drain valve electromagnet 45 is located on the pot lid 28 side, a failure due to water wetting does not occur. Further, when the boiling water in the pan 17 is discharged, there is no obstacle from the drain port 42 to the drain pipe 44, and the drain water is drained extremely well. Further, when the pot lid 28 is opened, the valve body 47 is attached to the pot lid 28 side, so that the surface of the grill pan 17 is flat, and there is no obstacle when cleaning with a scraper or the like. Work can be done easily. In other words, in order to newly cook the gyoza 39, it is necessary to lay new oil on the flat portion of the pot lid 28. Cleaning of the flat portion of the pot lid 28 is performed by removing food waste or oil on the flat portion of the pot lid 28. It is necessary to remove the sticking from the front to the back with a scraper, and it is a very important factor that the cleaning is easy.
[0068]
As is common to the first and second embodiments, the hot water tank 10 provided with the heater 11 may be omitted, and tap water may be supplied directly to the grill pan 17. is there. In this case, the cooking time is longer by 30 seconds to 1 minute, but it is not necessary for the user to generate hot water in the hot water tank 10 because there is a case where power supply to the heater 11 is omitted.
[0069]
In addition, the energization control to the drain valve solenoid valves 14 and 45 is linked to the time setting by the timer or the opening and closing of the pot lid 28, but is controlled manually without employing such energization control. It is also possible to do so.
