There is also a large part.

  The ventilation path 14 and the intake path 16 are configured such that the inside of the path and the inside of the lid main body 3 are completely shielded and isolated. If the steam passes through the steam path 15, liquid such as oneba or water flows from the pot 2. Even if it passes through the inside of each path, it flows out of the lid body 3 and does not enter the lid body 3. Further, the air passage 14 and the intake passage 16 are connected in communication with each other so that the air blowing means 11 is accommodated inside, and the liquid existing in the air passage 14 or the air intake passage 16 is inside the air passage 14 and the air intake passage 16. Although it can move and can also contact the air blowing means 11, it cannot move to the inside of the lid body 3, and if it flows out of other than the intake passage 16 and the air passage 14, it can be moved from the intake port 12 or the exhaust port 13.

Provided. A substantially annular inner lid packing 18 that is in close contact with the pan 2 when the lid main body 3 is in a closed state is attached to the surface of the outer peripheral portion of the inner lid 4 on the pan 2 side. The inner lid packing 18 is made of an elastic body such as rubber.

  A groove 19 is provided in the vicinity of the hinge axis A on the upper surface of the device body 1. When the outside air temperature is very low, when the lid body 3 is opened after cooking is finished, water droplets attached to the pan 2 side of the inner lid 4 may fall. It is provided in the range.

  On the outer surface of the lid main body 3, there are mounted display means 20 for displaying various information such as a rice cooking menu and time, and operation buttons 21 for starting, canceling, or making reservations for rice cooking. By operating the operation button 21, the cooking program incorporated in the control means 7 incorporated in the apparatus body 1 is executed, and the pan heating means 5 and the inner lid heating means 10 are operated and stopped in accordance with the progress of the cooking program. In addition, the operation and stop of the blower unit 11 are controlled by the control unit 7 in conjunction with the cooking process.

  The device body 1 is provided with a handle 22 for transportation. The handle 22 is pivotally supported at a substantially front-rear center of the upper side of the device main body 1, and the rotation direction of the handle 22 is substantially the same as the rotation direction of the lid main body 3. At the time of transportation, the handle 22 is rotated so that the handle 22 is lifted so that the handle 22 is positioned almost immediately above the shaft fulcrum of the handle 22, and the user can carry the device body 1 with the handle 22 alone. . When not transported, the handle 22 is supported in a substantially horizontal direction by the hinge cover 23 on the floor on which the device main body 1 is placed so as not to obstruct the opening and closing of the lid main body 3. The hinge cover 23 is attached to the rear part of the device main body 1 and hides the hinge shaft A serving as a pivot point of the lid main body 3 from the outside of the device main body 1 so that water droplets and foreign matters do not adhere to the hinge shaft A. Also, it plays a role of supporting the handle 22 so as not to rotate further downward.

  About the cooking appliance comprised as mentioned above, the operation | movement in the case of rice cooking as cooking is demonstrated below.

  First, a predetermined rice and water are set in the pan 2, a cooking menu is selected with the operation button 21, and a cooking start button is pressed to start the rice cooking process. The rice cooking process is a dipping process in which the water is kept at a constant temperature and the rice absorbs water, the pot 2 is heated at once by the pot heating means 5, the cooking process in which the water in the pot 2 is brought into a boiling state, It consists of a steaming process that suppresses heating while water is almost gone. During these processes, rice is gelatinized and cooked. The control means 7 optimally controls the pot heating means 5 according to the temperature of the pot 2 by the pot temperature sensor 6, and cooks rice according to a predetermined rice cooking program. There are several courses in the rice cooking program depending on the type of rice. When this steaming process ends, cooking rice ends, and the process automatically shifts to a heat retaining process, so that the temperature of the cooked rice does not decrease, and the user can always obtain warm rice.

  The detail of the operation | movement by rice cooking program execution is demonstrated below.

  When rice cooking is started, the soaking process is first started. The control means 7 heats the pot 2 with the pot heating means 5, detects the temperature of the water in the pot 2 with the pot temperature sensor 6, and adjusts it to a temperature at which rice gelatinization does not start (less than about 60 ° C.). Promote rice water absorption.

In the cooking process, water and heat are added to the rice to cause gelatinization. The control means 7 operates the pot heating means 5 to rapidly heat the pot 2 to bring the water in the pot 2 to a boiling state. At this time, boiling continuously occurs and a large amount of steam is generated. When the generated steam fills the pan 2, excess steam enters the blower path 14 via the steam path 15. The control means 7 detects that the water in the pot 2 has boiled by the pot temperature sensor 6 and operates the air blowing means 11. The air blowing means 11 sucks outside air from the air inlet 12 and blows air in the direction of arrow B in FIG. The steam guided from the steam path 15 to the blower path 14 is mixed with air at room temperature, and this mixed gas of air and steam is discharged out of the lid body 3 from the exhaust port 13. By mixing with air,
Since the vapor | steam density | concentration can be reduced, the temperature of the exhaust gas mixture falls. Since the steam path 15 is connected to the bottom surface of the blowing path 14, the steam discharged from the steam path 15 moves lighter and naturally upward than air, and easily mixes with air uniformly in the blowing path 14. It has become.

  During the cooking process, it is necessary for the control means 7 to adjust the heating power in accordance with the total number in order to set the rising speed of the water temperature to the optimum speed for cooking delicious rice. Moreover, in order to ensure rice cooking performance even after boiling, it is necessary to keep the rice at a high temperature for a certain period of time, and it is necessary to adjust the thermal power for that purpose. Therefore, in most cases, the pot heating means 5 adjusts the heating power by intermittently heating the pot 2. Therefore, steam is continuously generated in the pan 2 while the pan heating means 5 is operating, but steam generation in the pan 2 is stopped when the pan heating means 5 is not operating. When steam is generated in the pot 2, there is no place for the air in the pot 2 to move except for the steam path 15, so that when the pot 2 is filled with steam, the steam pressure increases, Then, the steam moves to the blowing path 14. Even if the air blowing means 11 is operating at this time, it is very difficult for the wind generated by the air blowing means 11 to be blocked by the steam coming out of the steam path 15 and enter the steam path 15.

  In addition, in the cooking process, components such as starch in the rice may be dissolved in water, and a high-viscosity Oneba that has become a film may flow out of the pan 2 together with steam. Oneva moves out of the pan 2 as being pushed by steam, but Oneba bursts when it is exposed to a gas having a temperature sufficiently lower than that of steam. The wind of the blowing means 11 intermittently enters the steam path 15 in accordance with the operation of the pan heating means 5, and cools the ambient temperature in the steam path 15 and the path wall surface of the steam path 15. Therefore, even if some Oneva enters, it is cooled and blown by the wind from the blowing means 11 in the vicinity of the blowing path 14, and there is an effect that it is difficult for Oneva to flow into the blowing path 14.

  Further, the steam with Oneba passes through the steam hole 4a having a small cross-sectional area (for example, 0.5 cm 2) at a high flow velocity, and then suddenly immediately above the steam hole 4 a of the steam path 15 having the large cross-sectional area (for example, 30 cm 2). When the flow velocity is further reduced and the flow velocity is increased again in the steam passage 15 having a small cross-sectional area (for example, 1 cm 2), the flow rate changes, and Oneva is likely to burst.

  However, when rice is cooked in the rice cake course with a large amount of water in the pan 2, or when the user accidentally supplies the pan 2 with a larger amount of water than the predetermined amount of water, the liquid containing oneba There is a possibility that the air may flow out to the air passage 14. Even in such a case, since the water storage part 17 is provided, the liquid is first stored in the water storage part 17, and moisture is evaporated into the atmosphere by the air blown from the air blowing means 11. For this reason, it is difficult for the liquid containing Oneva to accumulate in a place where the wind is difficult to pass, such as a gap between the blowing unit 11 and the blowing path 14. In particular, when the pot heating means 5 is stopped, the momentum of vapor entering the air blowing path 14 is reduced, so that the liquid stored in the water storage section 17 is likely to evaporate.

  Further, the steam that has moved from the inside of the pan 2 to the steam path 15 and the blower path 14 is cooled by the wall surface when the temperature of the wall surfaces of the steam path 15 and the blower path 14 is lower than the temperature of the steam. Arise. This also reduces the concentration of the steam discharged out of the lid body 3.

In the steaming process, almost no water remains in the pan 2, and while the excess water adhering to the rice is evaporated, the inside of the pan 2 is maintained at a high temperature (about 100 ° C) for gelatinization. Further progress. At this time, the control means 7 operates the inner lid heating means 10 while detecting the temperature of the upper space of the pan 2 with the inner lid temperature sensor 9, and continues to give heat to the rice, and the progress of gelatinization is continued. Promote. Even in the steaming process, the steam is discharged from the pan 2, but the amount is smaller than that in the cooking process. For this reason, the wind from the air blowing means 11 is more likely to enter the steam path 15, and the water storage section 17 is further increased.
The drying of the liquid becomes easier. As a result, in many cases, the liquid in the water storage part 17 evaporates, and rice cooking is completed in a state where the water storage part 17 is dry.

  With the above configuration, the cooking appliance of the present embodiment is provided with the water storage part 17 that stores the liquid that has flowed out through the steam path 15 in the air supply path 14, so that the liquid that has flowed into the air supply path 14 is stored in the water storage part 17. Since the water storage part 17 is dried by the wind from the ventilation means 11, it can be set as the cooking appliance which has the exhaust-gas low-temperature function which always maintains the ventilation path | route 14 clean.

  In addition, as shown in FIG. 1, by changing the cross-sectional area of the steam path outlet 15b, it is possible to control the momentum of discharge of the steam to the blower path 14, and when the cross-sectional area of the steam path outlet 15b is reduced, the steam Is expelled vigorously and more easily reaches the opposite side of the steam path outlet 15b of the blower path 14, while increasing the cross-sectional area of the steam path outlet 15b reduces the steam momentum, and the steam path outlet of the blower path 14 is further increased. It becomes difficult to reach to the opposite side to 15b. Accordingly, it is possible to optimally control the degree of mixing of steam and air by changing the cross-sectional area of the steam path outlet 15b in accordance with the cross-sectional area of the blower path 14.

  It is to be noted that the air blowing means 11 can be operated with two stages of air volume, and in the case of rice cooking, the air volume of the air blowing means 11 is lowered in the steaming process as compared with the cooking process, and the wind from the air blowing means 11 enters the steam path 15 If this is reduced, the effect of reducing the intrusion of cold air into the pan 2 may be obtained.

  It should be noted that if at least a part of the steam path 15 is detachably provided, the steam path 15, which is an easy passage for oneba or the like, may be easily maintained, and the steam path 15 may be attached or detached. Even if it is not possible, it may be configured such that a lid is provided so that the easily soiled portion can be cleaned by opening the lid.

  In addition, if the ventilation means 11 operate | moves at the time of discharge | evaporation of steam and can reduce the density | concentration of steam, it will not depend on the detection temperature of the pan temperature sensor 6, and in the case of rice cooking, it enters into a cooking process and operate | moves at fixed temperature. The operation may be started or operated by a temperature detected by another sensor such as the inner lid temperature sensor 9.

  In addition, when at least a part of the air passage 14 is provided so as to be detachable, even when liquid enters the air passage 14 during abnormal use, such as when cooking with a larger amount of water than usual, it is easy to clean. Alternatively, even if the air passage 14 cannot be attached or detached, a configuration may be adopted in which a lid is provided and the easily soiled portion can be cleaned by opening the lid.

  The steam path 15 is connected to the bottom surface of the air supply path 14, but the same effect can be expected near the bottom surface of the side surface of the air supply path 14, and the rib is connected to other parts of the air supply path 14. Even so, it suffices if steam and air can be mixed substantially uniformly.

  In addition, the inlet 12 should just be provided so that a pressure loss may become small so that the performance of the ventilation means 11 can fully exhibit according to the kind of the ventilation means 11, and a position and a shape may differ. In addition, the ventilation path 14 and the intake path 16 may be comprised with the same components.

  Although the air blowing means 11 is arranged at the rear part of the lid main body 3, it may be arranged at the front part of the lid main body 3, or may be arranged inside the device main body 1 so that the air flow path 14 is arranged in the device main body 1 and the lid main body. 3 may be provided. In that case, the air inlet 12 is provided in the device main body 1, but since the handle 22 or the hinge cover 23 is provided, the same effect can be obtained if it is arranged so as not to reduce the amount of air sucked in contact with the wall. can get.

  In addition, although the ventilation path 14 is a linear shape, other shapes, such as bending, may be sufficient.

  Moreover, although the rice cooker was illustrated as cooking equipment in this Embodiment, it is not restricted to this, If it is a cooking device which blows on the vapor | steam discharged | emitted during cooking and lowers | emits a vapor | steam density | concentration and is discharged | emitted It can be applied to both.

(Embodiment 2)
3 and 4 illustrate an electromagnetic induction heating rice cooker as a cooking device in Embodiment 2 of the present invention. About the same structure as Embodiment 1, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  As shown in FIG. 3, in the cooking appliance according to the present embodiment, the air blowing means 11 is disposed on the left rear side (upper left direction in the figure) of the lid body 3, and the air inlet 12 is formed in the side wall portion of the lid body 3 in the vicinity thereof. Is provided. The exhaust port 13 is provided on the right rear side of the lid body 3 in the direction opposite to the air blowing means 11, and the air blowing path 14 is structured to connect the air blowing means 11 and the air exhaust port 13 almost linearly. A water storage part 17 is provided on the bottom surface of the air blowing path 14 on the exhaust port 13 side from the connection part with the steam path 15, and the volume of the liquid in which the water storage part 17 is stored is about 10 ml.

  In FIG. 4, the floor surface portion of the air flow path 14 between the water storage unit 17 and the exhaust port 13 is an inclined surface 14 a that is inclined downward toward the exhaust port 13, and the liquid accumulated in the water storage unit 17 overflows. As shown by the arrow C in the figure, it flows to the exhaust port 13 and flows out of the lid body 3 from the exhaust port 13.

  About the cooking appliance comprised as mentioned above, the operation | movement in the case of rice cooking as cooking is demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When rice is cooked in the rice cake course with a large amount of water in the pan 2, or when the user accidentally supplies the pan 2 with a larger amount of water than the predetermined amount of water, the liquid containing the Oneba is the ventilation path. 14 may flow out. Even in such a case, since the water storage part 17 is provided, the liquid first accumulates in the water storage part 17, and the liquid evaporates into the atmosphere by the air blowing from the air blowing means 11. For this reason, it is difficult for the liquid containing Oneva to accumulate in a place where the wind is difficult to pass, such as a gap between the blowing unit 11 and the blowing path 14. Further, when a large amount of liquid overflowing from the water storage section 17 flows out of the vapor path 15, the liquid that cannot be stored in the water storage section 17 travels through the inclined surface 14a as shown by the arrow C in the figure and is discharged from the exhaust port 13. It is discharged out of the lid body 3.

  With the above configuration, the cooking appliance of the present embodiment is provided with the water storage part 17 and the air passage 14 is formed as an inclined surface 14a inclined downward toward the exhaust port 13 so that about 10 ml or more of liquid can be stored in the water storage part. Since the air does not collect in the air 17, the air in the water storage unit 17 can be dried more quickly by blowing air from the air blowing means 11. Therefore, the liquid overflowing from the water storage part 17 is also discharged out of the lid body 3 without entering the gap between the air blowing means 11 and the air blowing path 14, so that the air blowing path 14 can be further maintained in a sanitary excellent state. It can be set as the cooking appliance which has the exhaust-gas-temperature-reducing function which always keeps the ventilation path 14 clean.

  In addition, if the liquid of the water storage part 17 can be dried quickly, in the case of rice cooking, if discharge | release of the vapor | steam from the inside of a pan stops even in the middle of a steaming process, since the ventilation means 11 can be stopped immediately, energy saving property It will be excellent.

In the present embodiment, the water reservoir 17 is provided between the steam path 15 outlet and the exhaust port 13, but may be provided between the steam path 15 and the air blowing means 11, but in that case Inclined surface 14
It is necessary to provide a in a range including at least a part of the water reservoir 17.

  In addition, when the whole from the air blowing means 11 to the exhaust port 13 is inclined downward toward the exhaust port 13 without changing the arrangement of the water storage unit 17, splashes or the like flying between the air blowing unit 11 and the air blowing path 14 Furthermore, compared with the case where the floor surface of the ventilation path 14 is flat, it becomes easier to move to the exhaust port 13 and the water storage part 17, and it can be made more hygienic.

  In the case where the air blowing means 11 is unevenly distributed, it may be left or right, but the lid body 3 may be smoothly opened and closed closer to the center of the device body 1.

  In addition, if the steam path inlet 15c is not arranged directly under the air flow path 14, the height of the lid body 3 can be suppressed, and a compact cooking appliance can be obtained.

FIG. 5 illustrates an electromagnetic induction heating rice cooker as a cooking device in Embodiment 3 of the present invention. About the same structure as Embodiment 1, 2, the same code | symbol is attached | subjected and detailed description is abbreviate | omitted.

  As shown in the figure, the cooking appliance in the present embodiment is provided with an overflow channel 24 that connects the bottom surface of the air flow channel 14 and the bottom surface of the lid body 3 (lower side in the drawing) in the second embodiment. is there. The end of the overflow channel 24 on the lower surface side of the lid main body 3 faces the groove 19, and the liquid dropped through the overflow channel 24 is configured to accumulate in the groove 19. The groove 19 also serves as an overflow reservoir. The end of the overflow path 24 on the side of the air flow path 14 is connected with a part having a low step so that the liquid overflowing from the water storage section 17 preferentially flows into the overflow path 24.

  About the cooking appliance comprised as mentioned above, the operation | movement in the case of rice cooking as cooking is demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When rice is cooked in the rice cake course with a large amount of water in the pan 2, or when the user accidentally supplies the pan 2 with a larger amount of water than the predetermined amount of water, the liquid containing the Oneba is the ventilation path. 14 may flow out. The liquid that has flowed out into the air supply path 14 is accumulated in the water storage section 17. However, when the liquid volume is larger than the capacity of the water storage section 17, the liquid overflows from the water storage section 17 and the overflowed liquid passes through the water overflow path 24 to form the groove 19. Thus, the amount of liquid corresponding to the capacity of the water storage unit 17 remains in the water storage unit 17. Of course, when the rice is cooked with the normal amount of liquid, the liquid hardly flows into the air blowing path 14, so that the liquid is only stored in the water storage portion 17 and does not move into the groove 19.

  With the above configuration, the cooking device of the present embodiment includes the overflow path 24 that moves the liquid accumulated in the water storage section 17 over a certain amount and the overflow reservoir section (groove 19) that stores the moved liquid. The liquid that has flowed into the passage 14 is stored in the water reservoir 17. Although the water storage part 17 is dried by the wind by the air blowing means 11, when an excessive amount of liquid has accumulated in the water storage part 17, the excess amount passes through the overflow path 24 and moves to the overflow storage part. It becomes difficult for the liquid to accumulate in the air passage 14, and it can be a cooking appliance having an exhaust gas temperature reducing function that keeps the air passage 14 clean at all times. That is, by providing the overflow path 24 and the overflow reservoir, even when a large amount of water is cooked than usual, even if a large amount of water flows out to the blowing path 14, the liquid containing the Oneba or the like flows. To prevent the entire air passage 14 from becoming dirty and moving the liquid to the overflow reservoir (groove 19) that is easy for the user to maintain, minimizing the place where the liquid is contaminated, In addition, it can easily clean liquids that contain oneva that is the source of mold growth and odor.

  In addition, when the water storage part 17 cooks with the predetermined | prescribed liquid quantity, it dries by ventilation of the ventilation means 11, and sets the water storage amount so that a liquid may not remain in the water storage part 17 during cooking, and a water storage part No. 17 is naturally dried by the air blowing means 11 and the liquid containing the Oneba does not move to the overflow reservoir (groove 19). Therefore, it is not necessary to clean the overflow reservoir every time, and the care can be further improved. So good.

  Moreover, if the overflow path 24 is configured by a straight path, it is easy to care for. In addition, if the overflow path 24 has a diameter of about 5 mm or more, the wall surface in the overflow path 24 can be cleaned, and liquid containing Oneva or the like may remain and block the hole in the overflow path. .

Connected to the unit 25. The end of the overflow path 24 on the air blowing path side is provided on the hinge axis A side in the vicinity of the water storage section 17, and when the liquid in the water storage section 17 moves when the lid body 3 is opened, the liquid flows into the overflow path 24 preferentially. Is configured to flow in. The overflow reservoir 25 is detachable in the direction of the arrow D shown in the figure when the lid body 3 is opened, and cannot be removed when the lid body 3 is closed. The overflow reservoir 25 has a function similar to that of the groove 19 in the third embodiment, but is different in that it is detachable.

  About the cooking appliance comprised as mentioned above, the operation | movement in the case of rice cooking as cooking is demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When rice is cooked in the rice cake course with a large amount of water in the pan 2, or when the user accidentally supplies the pan 2 with a larger amount of water than the predetermined amount of water, the liquid containing the Oneba is the ventilation path. 14 may flow out. The liquid that has flowed out to the air supply path 14 is stored in the water storage section 17, but when the liquid volume is larger than the capacity of the water storage section 17, the liquid overflows from the water storage section 17 and the overflowed liquid passes through the overflow path 24 and accumulates overflow. It flows out to the part 25 and the amount of liquid corresponding to the capacity of the water storage part 17 is left in the water storage part 17.

  When the humidity of the surrounding environment where the rice cooker is placed is very high, it is difficult for water vapor to dissolve in the air, and even when the air is blown by the air blowing means 11, the liquid in the water storage unit 17 may not be completely dried. . In that case, a liquid may remain in the water storage part 17 even after the cooking of rice. However, since the end of the overflow path 24 on the side of the air flow path 14 is provided on the hinge axis A side of the air flow path 14, the liquid remaining in the water storage section 17 when the lid body 3 is opened moves to the overflow reservoir 25. Cheap.

  When the air blowing means 11 is driven, if the overflow path 24 is connected to the outside air space as shown in the third embodiment, the air from the air blowing means 11 partially leaks from the overflow path 24 and mixes with the steam. Although the amount is reduced, in the configuration of the present embodiment, the overflow reservoir 25 is hermetically sealed except for being connected to the overflow path 24, so that the wind does not leak. Therefore, it is possible to effectively maintain the steam chilling function.

With the above configuration, the cooking apparatus according to the present embodiment can easily handle liquids such as Oneba and water that have moved from the blowing path 14 by allowing the overflow reservoir 25 to be detachable. Convenience is good, and it can be set as the cooking appliance which can keep the overflow reservoir 25 hygienic, and has the exhaust-temperature low-temperature function which always keeps the ventilation path 14 clean.

  In addition, in order to detect whether or not the overflow reservoir 25 is normally set, if detection means such as a push switch is provided and cooking is started without the overflow reservoir 25 being set, that effect Can be reduced without the overflow reservoir 25 being set, and the liquid falling into the groove 19 can be reduced.

  The overflow reservoir 25 may be provided in another part such as the outer part of the lid main body 3 or the apparatus main body 1, or the groove 19 of the apparatus main body 1 may be provided detachably. .

  As shown in the drawing, in the cooking appliance according to the present embodiment, the bottom surface of the air blowing path 14 is an inclined surface 14 b that is inclined downward toward the water storage unit 17. As a result, liquid such as Oneva or water that has flowed into the air flow path 14 is easily collected in the water storage section 17.

  About the cooking appliance comprised as mentioned above, the operation | movement in the case of rice cooking as cooking is demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When rice is cooked in the rice cake course with a large amount of water in the pan 2, or when the user accidentally supplies the pan 2 with a larger amount of water than the predetermined amount of water, the liquid containing the Oneba is the ventilation path. 14 may flow out. By making the bottom surface of the ventilation path 14 into the inclined surface 14b, it becomes easy to be led to the water storage part 17 wherever the liquid containing the Oneba flies anywhere in the ventilation path 14.

  With the above configuration, the cooking appliance of the present embodiment uses the bottom surface of the air passage 14 as the inclined surface 14b that inclines downward toward the water storage section 17, so that the liquid that has flowed into the air passage 14 is stored in water. The water storage unit 17 is dried by the wind from the air blowing means 11. Thereby, it can be set as the cooking appliance which has the exhaust_gas | exhaustion temperature reduction function which always maintains the ventilation path 14 clean.

  As shown in FIG. 8, a step E is provided on the bottom surface of the air blowing path 14 and the support bottom surface of the air blowing means 11 so that at least a part of the bottom surface is lower than the bottom surface of the air blowing means 11. It is possible to further reduce the entry of the liquid containing the Oneva into the portion where the wind between the blowing means 11 and the blowing path 14 is difficult to reach, and to keep the blowing path 14 more hygienic. .

  Further, as shown in FIG. 8, the water storage portion 17 is provided between the steam path 15 and the exhaust port 13, and the connection direction of the steam path 15 with the air blowing path 14 is different from the air blowing means 11. Since the liquid flowing out to the blower path 14 through the vapor path 15 does not easily reach the blower means 11 as indicated by an arrow F in the figure and is easily stored in the water storage part 17, liquid such as oneba or water is a substrate of the blower means 11. It is possible to obtain a cooking appliance having a more reliable function of reducing the temperature of the exhaust gas.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When a liquid such as oneba or water flows into the air flow path 14, the liquid accumulates in the water storage unit 17. Since the overflow path 24 is in contact with the groove 19, the liquid does not flow into the overflow path 24 unless the lid main body 3 is opened, and the water storage section 17 is dried by the blowing by the blowing means 11. Even after cooking, when the lid body 3 is opened without the water storage part 17 being completely dried and rotated about 90 °, the close contact between the overflow path 24 and the groove 19 is eliminated, so all the liquid accumulated in the water storage part 17 overflows. It moves through the path 24 to the groove 19.

  With the above configuration, the cooking device according to the present embodiment connects the overflow path 24 to the bottom surface of the water storage unit 17, thereby reliably moving the liquid stored in the water storage unit 17 after cooking to the overflow storage unit. Since the passage 14 can be in a sanitary state and can be easily cared for liquids including Oneva, etc., the liquid is less likely to accumulate in the air passage 14 and the exhaust air temperature is always kept clean. It can be set as the cooking appliance which has a control function.

  Further, the overflow path 24 is connected to the hinge axis A side that allows the lid body 3 of the water storage section 17 to be opened and closed, so that when the lid body 3 is opened, the liquid remaining in the water storage section 17 is more easily moved. A further effect can be exhibited.

  In addition, in said each Embodiment 1-6, in the case of rice cooking, if the Oneba recirculation path | route which returns the Oneva which remained in the steam path 15 in the pot 2 from the steam hole 4a is provided, Oneba will cook in the pot 2 ( It will re-adhere to the rice and the cooking will be better.

  In each of the first to sixth embodiments, the exhaust direction may be a horizontal direction, a diagonally upward direction, an upward direction, or the like, and the direction is not limited.

  In each of the first to sixth embodiments, the air blowing means 11 may be of any type as long as air can be blown by an axial fan, a sirocco fan, or another fan. When the entire blower unit 11 including the substrate for driving the blower unit 11 is disposed in the blower path 14, the liquid is blown when the substrate enters the blower path 14 and the liquid enters the blower path 14. It becomes difficult to contact the board | substrate of the means 11, and the board | substrate of the ventilation means 11 becomes difficult to break down.

  As described above, the cooking device according to the present invention can be a cooking device that has a function of reducing the temperature of exhaust gas by performing processing of liquids such as Oneva and water in the air blowing path and always keeping the air blowing path clean.
