  This invention is equipped with the heat retention function which hold | maintains the rice after cooking at predetermined | prescribed temperature (generally 70-75 degreeC), and was made to suppress discharge | emission of the high temperature steam which generate | occur | produces from a pan during rice cooking. It is about.

  Conventionally, rice cookers have already been proposed in which air is blown into steam discharged during rice cooking, and the concentration of the steam is lowered and discharged as a mixture (see, for example, Patent Documents 1 and 2). Here, Patent Document 2 will be described in particular.

As shown in FIG. 19, a part of the configuration includes a blower device 31, a blower path 32, and a steam pipe 34 communicating with the pan 33 in the lid body 30. The air from the blower 31 is supplied to the steam from the blower passage 32 in the blower path 32, and the concentration of the steam is lowered and discharged from the exhaust port 35 to the outside of the rice cooker body as a mixture.
Japanese Patent No. 1823119 Japanese Patent No. 3682252

  However, in the conventional configuration, the end of the steam pipe 34 on the side of the air flow path 32 opens toward the exhaust port 35, so that the air blown from the air blower 31 is less likely to enter the steam pipe 34. It has become so that the gelatinization of rice is not hindered. However, since the steam flow is directed by the steam pipe 34 so as to flow substantially parallel to the wind flow by the blower 31, the steam and the blown air are discharged as they are without being sufficiently mixed. The original purpose of suppressing the discharge of high-temperature steam is not sufficiently obtained.

  The present invention solves the above-mentioned conventional problems, and provides a rice cooker that can make both delicious rice cook and mixing steam and air sufficiently to lower the temperature of discharged steam. Objective.

In order to solve the above-mentioned conventional problems, the rice cooker of the present invention opens and connects the steam path outlet of the steam path to a substantially vertical path wall farthest from the hinge shaft of the blower path , The steam path inlet communicating with the inside of the pan is arranged by shifting the position in the horizontal direction.

As a result, the position of the steam path outlet and the steam path inlet is shifted in the horizontal direction, so that when the blower is operated during cooking, room temperature air sent from the blower is placed in the pan. Entering can be reduced, and rice cooking performance can be maintained high. In addition, since the steam path outlet is opened in the path wall of the blower path, the steam from the steam path reaches the blower path without being directed, and is uniform due to the turbulent flow generated by friction with the path wall. In this way, the exhaust steam is mixed with the blown air, and the discharged steam can be further cooled. Furthermore, the steam path is connected to a substantially vertical path wall that is farthest from the hinge axis of the blower path, so that condensation occurs in the blower path during heat insulation, and then the lid is opened and closed to allow dew condensation to enter the steam path. Since it can reduce, the heat retention rice right under a steam path entrance does not whiten, and heat retention performance can be maintained highly.

  The rice cooker of the present invention is capable of making both delicious rice and lowering the temperature of exhaust steam.

This makes it possible to reduce the room temperature air sent from the blower device from entering the pan when the blower device is operated during rice cooking, because the steam path is bent. You can cook delicious rice. In addition, since the steam path outlet is opened in the path wall of the blower path, the steam from the steam path reaches the blower path without being directed, and is uniform due to the turbulent flow generated by friction with the path wall. In this way, the exhaust steam is mixed with the blown air, and the discharged steam can be further cooled.

Since it can reduce, the heat retention rice right under a steam path entrance does not whiten, and heat retention performance can be maintained highly.

  In a third aspect of the invention, in particular, in the first aspect of the invention, the steam path has a steam path outlet provided closer to the hinge shaft than the steam path inlet. As a result, it is possible to reduce the condensation from falling into the pan even when condensation occurs in the air flow path during heat insulation, and then the lid is opened and closed and the condensation enters the steam path. The rice right under the route entrance does not become white and swell. Even when condensation occurs in the steam path, the condensation moves to the hinge side each time the lid is opened, so that the rice does not become white and does not swell.

According to a fourth aspect of the invention, in particular, in the first or second aspect of the invention, the air blower is disposed other than between the air passage and the hinge shaft, so that dew condensation occurs in the air passage during the heat insulation, and the lid is then installed. It is possible to reduce the occurrence of condensation due to condensation on the blower when it is opened and closed.

In a seventh aspect of the invention, in particular, in the first or second aspect of the invention, an air intake path that communicates the air blower with outside air is provided, and the air intake path has a lower bottom surface of the air intake path than the bottom surface of the air supply path. Since some of them are directly connected to the intake passage without going through the blower, they accidentally supply water that is different from the predetermined amount into the pan and cook rice, and a large amount of water flows into the blower passage. Even when a large amount of water is accidentally supplied from the exhaust port, the water that has flowed into the air passage does not contact the air blower and is discharged outside through the air intake passage. This can reduce the cause of failure.

In an eighth aspect of the present invention, in particular, in the first or second aspect of the present invention, an air intake path that communicates the air blower with the outside air is provided, the air intake path includes an air intake at a connection portion with the outside air, and the air intake is a fan.

According to a ninth aspect of the present invention, in particular, in the first or second aspect of the present invention, the ventilation path is arranged at the lower part of the top surface of the lid main body, and is detachable by sliding from the rear side. It is possible to reduce the possibility that the foreign substance is caught between the connection part between the air blowing path and the steam path and the high-temperature steam leaks out before mixing with the air at room temperature, and the user is burned.

In the tenth aspect of the invention, in particular, in the ninth aspect of the invention, the steam path is detachable separately from the blowing path, so that the parts integrated with the blowing path and the steam path are very long in the front-rear direction of the rice cooker. So, it is very difficult to attach and detach when sliding backward, but the steam path is detached from the pan side of the lid body with the lid open, and the ventilation path is detachably detached from the rear, such as sliding from the rear. If possible, it is easy to attach and detach and easy to use.

In an eleventh aspect of the invention, in particular, in any one of the first to third aspects of the invention, the control device operates to operate the blower for a certain period of time even after the completion of rice cooking, so that air with high humidity in the blower path is removed. Since it can extrude out of the rice cooker main body, the dew condensation in the ventilation path can be reduced, and it is possible to further reduce the dew condensation entering the pan during the heat insulation.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

An inner lid heating coil, which is an example of the inner lid heating device 10, is installed in the lid body 3 and is configured to inductively heat the inner lid 4 under the control of the control device 7. The hinge shaft 3a is an opening / closing shaft of the lid body 3, and both ends of the hinge shaft 3a are fixed to the upper frame 1c of the rice cooker body 1 so as to be rotatable. The lid body 3 is urged to rotate by a rotation spring (not shown) provided in the vicinity of the hinge shaft 3a.

  The blower 11 is disposed at the rear portion of the lid body 3 on the hinge shaft 3a side, that is, at a location near the hinge shaft 3a. The air inlet 12 is composed of a plurality of slit-like holes on the side surface of the lid body 3. The exhaust port 13 is composed of a plurality of slit-shaped holes on the inclined top surface of the lid body 3. The air blowing path 14 connects the exhaust side 11b and the exhaust port 13 in a substantially straight line, and the cross-sectional area is also substantially uniform.

  The steam path 15 connects the steam path inlet 15c at one end to the steam port 4a of the inner lid 4 and connects the steam path outlet 15b at the other end so that excess steam in the pan 2 can be discharged to the blowing path 14. An opening is formed in the path wall 14a of the air blowing path 14 between the air outlet 13 of the air blowing path 14 and the exhaust side 11b. The steam path 15 is arranged such that the steam path outlet 15b is shifted in the horizontal direction to the hinge shaft 3a side with respect to the steam path inlet 15c communicating with the inside of the pan, and the path between the steam path inlet 15c and the steam path outlet 15b is arranged. It is bent. With this configuration, the steam path 15 forms a wind intrusion prevention structure 16 in the path. The steam path 15 is made of a path wall surface made of resin.

  In the present embodiment, the steam path outlet 15b of the steam path 15 is connected to the blowing path 14 in a direction (substantially vertical direction) shifted by 10 to 20 degrees from the vertical direction and opens to the path wall 14a. The wind entry preventing structure 16 has a substantially horizontal portion 16a that is difficult to reach the pan 2 even when wind from the blower 11 enters the steam path 15, and a bent portion 16b that is bent at a right angle. The outflow direction of the steam from the steam path 15 is configured to be substantially perpendicular to the flow direction of the wind from the blower device 11 in the blower path 14.

  A part of the inner lid 4 is made of a metal such as stainless steel that can be induction-heated, and is provided with the above-described steam ports 4 a formed of a plurality of holes in order to discharge steam to the outside of the pan 2. A substantially annular inner lid packing 17 that is in close contact with the pan 2 when the lid main body 3 is in the closed state is attached to the side surface of the pan 2 on the outer peripheral portion of the inner lid 4. The inner lid packing 17 is made of an elastic body such as rubber.

  On the outer surface of the lid body 3, a display unit 18 for displaying various information such as a rice cooking menu and time, and operation buttons 19 for starting, canceling, and making reservations for cooking rice are mounted. By the operation of the operation button 19, the rice cooking program incorporated in the control device 7 incorporated in the rice cooker body 1 is executed, and the pan heating device 5 and the inner lid heating device 10 are operated and stopped according to the progress of the rice cooking program. While performing rice cooking, also regarding the air blower 11, operation | movement and a stop will be controlled by the control apparatus 7 in conjunction with a rice cooking process.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, predetermined rice and water are set in the pan 2, the rice cooking menu is selected with the operation buttons 19, and the rice cooking start button is pressed to start the rice cooking process. The rice cooking process is a water immersion process in which water is kept at a constant temperature and the rice absorbs water, the pot 2 is heated at once by the pot heating device 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 device 7 optimally controls the pan heating device 5 according to the temperature of the pan 2 by the pan 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 is completed, 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.

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

  When rice cooking is started, the water immersion process is first started. The control device 7 heats the pan 2 with the pan heating device 5, detects the temperature of the water in the pan 2 with the pan 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 device 7 operates the pan heating device 5 to rapidly heat the pan 2 to bring the water in the pan 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 steam path 15, enters the blower path 14 through the wind intrusion prevention unit 16. The control device 7 detects that the water in the pan 2 has boiled by the pan temperature sensor 6 and operates the blower device 11. The blower 11 sucks outside air from the air inlet 12 and blows air in the direction of arrow B in the figure, and discharges room temperature air to the blower path 14. The steam guided from the steam path 15 to the blowing path 14 is mixed with air at room temperature, and the mixture of air and steam is discharged out of the lid body 3 from the discharge port 13. Since the vapor concentration can be reduced by mixing with air, the temperature of the discharged mixed gas is lowered. In addition, since the steam path outlet 15b of the steam path 15 is open and connected to the path wall 14a of the blowing path 14, the steam discharged from the steam path 15 is lighter than air and naturally moves upward. It becomes easy to mix with air uniformly in the ventilation path 14.

  During the cooking process, the control device 7 needs 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. In addition, it is necessary to keep the rice at a high temperature for a certain period in order to make the rice sufficiently soft even after boiling, and for that purpose it is necessary to adjust the heating power. Therefore, in most cases, the pot heating device 5 adjusts the thermal power by heating the pot 2 intermittently. Therefore, steam is continuously generated in the pan 2 while the pan heating device 5 is operating, but steam generation in the pan 2 is stopped when the pan heating device 5 is not operating. When steam is continuously generated in the pot 2, the air in the pot 2 has no place to move other than the steam path 15, so that when the pot 2 is filled with steam, the pressure of the steam increases, The steam moves to the blower path 14 via the path 15.

  Even if the blower 11 is operating at this time, it is very difficult for the wind generated by the blower 11 to be blocked by the steam coming out of the steam path 15 and enter the steam path 15. On the other hand, when generation | occurrence | production of a vapor | steam stops in the pan 2, the vapor | steam which entered into the vapor | steam path | route 15 becomes light compared with air at the high temperature of about 100 degreeC, and becomes easy to move upwards. At this time, a substitution occurs between the air at room temperature (for example, 20 ° C.) sent from the blower 11, and a phenomenon occurs in which the steam exits the blower path 14 and the wind from the blower 11 enters the steam path 15. . If air at room temperature enters the pot 2, the temperature in the pot 2 is lowered, so that the gelatinization of the rice becomes insufficient and it becomes impossible to cook delicious rice. However, in the cooking process, since the time for stopping the operation of the pan heating device 5 is usually short (for example, 5 seconds or less), the wind entry preventing structure 16 is provided in the steam path 15 and the bent portion 16b enters. By reducing the momentum of the wind, and providing a long horizontal path 16a to the pan 2 to increase the distance to the pan 2, it is possible to reduce the wind from the blower 11 from entering the pan 2.

  The wind that has moved from the blower 11 in the blower path 14 becomes turbulent in the vicinity of the wall surface due to friction with the wall surface, and tends to be laminar in the central portion of the blower path 14 that is away from the wall surface. Since the steam path outlet 15b is open to the wall surface of the air blowing path 14, the steam that has flowed into the air blowing path 14 is first caught in the turbulent flow near the wall surface, and is easily mixed with air. On the other hand, when steam is mixed with air at the center of the air blowing path 14, it is difficult to mix with air because it is a laminar flow. Further, since the steam path 15 is connected substantially perpendicularly to the air blowing path 14, the flow of the steam flows into the air blowing path 14 in the direction perpendicular to the flow of the wind from the blower 11, so that the steam further flows into the air. Easy to mix with.

  In addition, in the cooking process, components such as starch in the rice may dissolve into water, and a thick rice cake that is in the form of a film may flow out of the pan 2 with steam. The rice cracker moves out of the pan 2 as being pushed by the steam, but it bursts when it is exposed to a gas having a temperature sufficiently lower than the steam. The wind of the blower 11 enters the steam path 15 intermittently in accordance with the operation of the pan heating apparatus 5, and cools the atmospheric temperature in the steam path 15 and the path wall surface of the steam path 15. For this reason, even if a small amount of rice enters, it is cooled and ruptured by the wind from the blower device 11 in the vicinity of the air blowing path 14, so that there is an effect that it is difficult for the water to flow into the air blowing path 14.

  Moreover, when the temperature of the path | route wall surface of the steam path 15 and the ventilation path 14 is lower than the temperature of steam, the vapor | steam which moved to the steam path 15 and the ventilation path 14 from the inside of the pan 2 is cooled by the wall surface, and dew condensation arises. . This also reduces the concentration of the steam discharged out of the lid body 3. Further, such condensation is likely to occur in a place where the temperature difference is large, and in the case of the present embodiment, condensation is most likely to occur near the steam path outlet 15b. In the conventional rice cooker (FIG. 19), since the path (steam pipe 34) corresponding to the steam path 15 is inclined, if the dew condensation flows into the steam pipe 34, it easily enters the pan 33. However, the dew condensation that occurs near the steam path outlet 15b falls to the bent part 16b of the wind intrusion prevention unit 16, but the accumulated dew does not easily reach the pan 2 because the path 16a is horizontal. In the cooking process and steaming process during rice cooking, it is a condition of delicious rice to keep the inside of the pan 2 at a high temperature, but when the condensed water enters the pan 2, the temperature in the pan 2 is lowered and the taste is lowered. . Further, when condensed water enters the pot 2 during the heat retention, the whitening phenomenon in which the rice just below the steam outlet 4a contains a lot of moisture and swells in white occurs, resulting in a decrease in heat retention performance. In the present embodiment, since the wall surface of the vapor path 15 is made of resin, the heat insulating property is higher than that of metal and condensation is less likely to occur.

  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 device 7 operates the inner lid heating device 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. Therefore, it becomes easier for the wind from the blower 11 to enter the steam path 15. However, the horizontal long path 16a which is a part of the wind entry prevention structure 16 makes it difficult for the wind from the blower 11 to reach the pan 2, and the provision of the bent portion 16b allows the flow of steam to be bent. Since it becomes a turbulent flow in 16b and it becomes easy to push back the cold wind from the air blower 11, it can reduce that room temperature air reaches | attains the pan 2. FIG.

At the time of heat insulation, the inside of the ventilation path 14 warmed to room temperature by rice cooking is gradually cooled by room temperature, and dew condensation occurs when the humidity in the ventilation path 14 is high. In the vertical pipe-shaped steam path 15 as shown in Patent Document 1, when the lid body 3 is opened , dew condensation in the blower path 14 enters the steam path 15 and flows into the steam path 15 when the lid body 3 is closed. There was a problem that the water droplets dropped into the pan 2 and the rice directly under the steam path inlet 15c swelled white, and the taste was lowered. However, in the present embodiment, the steam path outlet 15b is shifted from the steam path inlet 15c toward the hinge shaft 3a, so that dew condensation in the blower path 14 is generated in the steam path 15 when the lid body 3 is opened. Even if the lid body 3 is closed, the water stays in the substantially horizontal portion 16a that is the horizontal path of the steam path 15 and the possibility of entering the pot 2 is very low.

With the above configuration, the rice cooker of the present embodiment reduces the steam temperature to be discharged, and even when the wind from the blower enters the steam path, the wind intrudes into the pot by the wind intrusion prevention unit. The steam temperature reduction function that reduces the inhibition of gelatinization that occurs when air at room temperature intrudes into a pan of about 100 ° C and lowers the temperature in the pan, improving the rice cooking performance. It becomes possible to provide a rice cooker. Moreover, it can reduce that rice balls enter into the ventilation path, and provide a rice cooker that can be easily washed. Also, by bending the steam path and shifting the steam path inlet and the steam path outlet in the horizontal direction, the steam path is lengthened while reducing the room temperature air sent by the blower from entering the pan, A lid can be made thin and it becomes possible to comprise a rice cooker compactly. Furthermore, even if water flows into the steam path at the time of heat retention, the water droplets do not easily enter the pot, so that it is possible to reduce the dripping of water into the heat retaining rice and the rice swelling white.

  Note that the path 16a does not necessarily have to be in the horizontal direction, and may be oblique, but may be shifted so that the steam path outlet 15b is not located directly above the steam path inlet 15c.

  In addition, if the outer side of the wall surface of the steam path 15 is covered with a heat insulating material or the like, condensation may be less likely to occur on the inner wall surface of the steam path 15.

  In the present embodiment, the path 16a of the steam path 15 is in the horizontal direction, but if it is configured to be higher as it approaches the steam path inlet 15c and lower as it approaches the steam path outlet 15b, it is more difficult for condensation to enter the pan 2. It will be good.

  Further, by configuring the exhaust side 11b and the discharge port 13 to face each other, the wind flows without resistance, and the air volume can be increased as compared with the bent air passage 14, and the air blower 11 with a lower price and a lower air volume can be obtained. Even if it uses, it will become possible to make it the air volume more than equivalent to the case of the bent ventilation path 14. Moreover, since the air blower 11 with a smaller air volume is basically smaller, the lid body 3 can be configured in a compact manner, and a rice cooker that is compact and easy to install can be provided.

  Even if the blower 11 is disposed in front of the lid main body far from the hinge shaft 3a, if the steam path outlet 15b is shifted so as not to be disposed immediately above the steam path inlet 15c, the steam enters the pan 2. The effect of being difficult is obtained.

  Further, since the blower 11 is disposed in the lid main body 3 at a location close to the hinge shaft 3a, the force required to open the lid main body 3 can be reduced, so that a rotating spring (not shown) ) Can be reduced. Thus, when the force of the rotating spring is large, a large force is applied when the lid body 3 is fully opened to an angle of about 90 degrees with respect to the rice cooker body 1, and when the pan 2 is empty, the rice cooker The problem that the main body 1 tends to float can be reduced, and a convenient rice cooker can be provided. Moreover, when the force of the rotating spring is large, the spring itself becomes large, but the entire rice cooker may be made compact by disposing the blower device 11 in the vicinity of the hinge shaft 3a.

  In addition, 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 exhausted vigorously. On the other hand, when the cross-sectional area of the steam path outlet 15b is increased, the momentum of the steam is reduced and it is more difficult to reach the side opposite to the steam path outlet 15b of the blower path 14. Become. 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.

  In addition, as means for preventing the wind from the blower 11 from entering the pan 2, the operation of the blower 11 and the operation of the pan heating device 5 are synchronized, and the blower 11 is only operated while the pan heating device 5 is operating. The same effect can be obtained by controlling to operate.

It should be noted that the blower 11 can be operated with two stages of air volume, the air volume of the blower 11 is reduced in the steaming process compared to the cooking process, and the speed at which the wind from the blower 11 enters the steam path 15 is reduced. The effect of reducing the penetration of cold air into the pan 2 may be obtained.

  If at least a part of the steam path 15 is detachably provided, the steam path 15 that is easy to pass through may be easily cleaned, and the steam path 15 can be detached. A configuration may be adopted in which a lid is provided at least in part, and cleaning of easily contaminated portions can be performed by opening the lid.

  In addition, if the air blower 11 operates at the time of discharge | emission of steam and can reduce the density | concentration of steam, it will not depend on the detection temperature of the pan temperature sensor 6, but will enter a cooking process and will start operation | movement at fixed temperature, You may operate | move by the detected temperature of other sensors, such as the inner cover temperature sensor 9. FIG.

  In addition, when at least a part of the air blowing path 14 is detachable, cleaning is easy even if the toy or water enters the air blowing path 14 during abnormal use such as when cooking with a larger amount of water than usual. Even if the air flow path 14 cannot be attached / detached, a configuration may be adopted in which a lid is provided in part, and a portion that is easily contaminated can be cleaned by opening the lid.

  The steam path 15 is connected to the path wall 14a on the bottom surface of the blower path 14, but the same effect may be expected even if connected to other path walls 14a.

  In addition, the inlet 12 should just be provided so that a pressure loss may become small so that the performance of the air blower 11 may fully exhibit according to the kind of air blower 11, and a position and a shape may differ. Moreover, since the inside of the lid body 3 is often not an airtight space and is connected to the outside air somewhere, if there is no hindrance to the air blowing of the air blower 11, it does not have a suction port 12 and has existed conventionally. The gap between the lid body 3 to be communicated with the outside air may be used as the suction port 12.

  In addition, although the air blower 11 is arrange | positioned in the rear part of the lid body 3, you may arrange | position in the lid body 3 front part, arrange | position in the rice cooker main body 1, and the ventilation path | route 14 in the rice cooker main body 1 and It may be provided over the lid body 3.

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

  Further, as shown in FIG. 3, the blowing device 11 is unevenly distributed on the left side of the rear portion of the lid body 3, the exhaust port 13 is provided on the right side, and the blowing direction is set in the horizontal direction as indicated by the arrow B. For the direction, the function of mixing steam with room temperature air and discharging it out of the rice cooker body may be achieved.

  In addition, when making the air blower 11 unevenly distributed, either right or left may be sufficient, but the direction close | similar to the center of a rice cooker main body may open / close the lid main body 3 smoothly.

  In addition, if the vapor | steam path | route inlet 15c is not arrange | positioned directly under the ventilation path | route 14, the height of the lid | cover main body 3 can be suppressed, and it can become a compact rice cooker.

(Embodiment 2)
4 and 5 show a rice cooker according to Embodiment 2 of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 4, the rice cooker in the present embodiment has a larger cross-sectional area (for example, about double) than the cross-sectional area of the steam path outlet 15 b of the steam path 15 in the middle of the steam path 15. The enlarged space portion 20 is provided. Other configurations are the same as those of the first embodiment.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. In the cooking process and the steaming process, when the air blower 11 operates, the wind from the air blower 11 may enter the steam path 15. However, since the flow rate of the wind that has entered the steam path 15 decreases as soon as it enters the expansion space portion 20, the momentum to move to the pan 2 side is further reduced, and the cold air is less likely to enter the pan 2. .

  On the other hand, in the cooking process, when boiling continuously occurs, if the steam path 15 is long, there is a risk that the sound of steam ejection may increase. It is possible to reduce the flow rate of the steam and lower the eruption sound.

  With the above configuration, the rice cooker according to the present embodiment reduces the steam temperature to be discharged, and even when the wind from the blower enters the steam path, the expanded space portion allows the wind to enter the pan. Since it can be further reduced, reducing the gelatinization of rice caused by the intrusion of room temperature air into the pan at about 100 ° C and lowering the temperature in the pan, to maintain high rice cooking performance Is possible. In addition, it is possible to provide a quiet rice cooker that can reduce the sound of steam ejection during boiling.

  Further, as shown in FIG. 5, the steam path 15 is formed by bending the path between the steam path inlet and the steam path outlet, but by using an inverted U-shaped structure 21 instead of the enlarged space portion 20, It is possible to make it difficult for the wind from the blower 11 to enter the pan 2. The bottom surface 21 a at the rearmost part of the path of the inverted U-shaped structure 21 is configured to be higher than the lowest point 15 a of the highest part of the path between the inverted U-shaped structure 21 of the steam path 15 and the air blowing path 14. Note that the cross-sectional area of the inverted U-shaped structure 21 is substantially the same as the cross-sectional area of the steam path 15.

  Here, in the cooking process and the steaming process, the steam from the pot 2 enters the steam path 15 as the water in the pot 2 boils. The steam that has entered the steam path 15 passes through the inverted U-shaped structure 21 and enters the blowing path 14. At this time, since the steam path 15 is not closed by a valve or the like, the steam flows without resistance to the blowing path 14, and excess steam in the pot 2 is discharged out of the pot 2 without resistance. On the other hand, when boiling stops, the internal pressure in the pan 2 does not increase, and thus it basically does not move. The replacement proceeds in the form of heavy air entering the steam path 15 instead. In the inverted U-shaped structure 21, light steam rises and stays in a portion higher than the bottom surface 21 a, so that the steam closes the steam path 15, and replacement with cold air hardly occurs.

  Moreover, even if dew condensation occurs at the steam path outlet 15b and falls to the steam path 15 and flows backward to the pan 2 side, the bottom surface 21a can prevent inflow into the pan 2.

  With the above configuration, the rice cooker of the present embodiment reduces the steam temperature to be discharged, and even when the wind from the blower enters the steam path, room temperature air enters the pot due to the inverted U-shaped structure. Can be further reduced, reducing the inhibition of the progress of gelatinization of rice that occurs when air at room temperature penetrates into a pan of about 100 ° C atmosphere and the temperature in the pan is lowered. It can be kept high.

Even when the bottom surface 21a of the inverted U-shaped structure 21 is not higher than the lowest point 15a of the highest portion of the path between the inverted U-shaped structure 21 of the steam path 15 and the blower path 14, the inverted U-character of the steam path. If the room temperature air that has entered the steam path 15 from the blowing path 14 enters the pot 2 as long as it is higher than the lowest point 15d of the path between the structure 21 and the blowing path 14, the lowest point 15a portion that is one step higher is used. It is necessary to get over, and the steam staying above the lowest point 15a in the highest part of the steam path becomes resistance, so that there is an effect that room temperature air hardly enters the pot 2.

(Embodiment 3)
6 and 7 show a rice cooker according to Embodiment 3 of the present invention. The same components as those in the first and second embodiments are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 6, the steam path 15 of the rice cooker in the present embodiment has a bend inhibiting portion 22 that obstructs a bend entering the blower path 14. The knee blocker 22 has a projection shape that can easily rupture a membrane-like bed, and the tip of the projection shape is inclined and pointed. The rice ball is divided into two arrows E1 and E2 in the figure so as to advance along the steam path 15.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. In the cooking process, a film-like rice ball enters the steam path 15 together with the steam. In the steam path 15, there is generally a blocking portion 22, which is divided into two arrows E 1 and E 2 and travels along the steam path 15. Since the path of the arrow E1 is gradually narrowed, the speed of the goblet and steam is faster, and the path of the arrow E2 is the path is gradually expanding, so the speed of the goblet and steam is slower. . If these different speeds hit at the meeting point, they will burst easily due to the difference in speed. The ruptured film-like rice cake falls down the passage as it is, flows back into the pot 2, and has the effect of reattaching to the rice and increasing the gloss of the rice.

  With the above configuration, the rice cooker of the present embodiment is easy to use because the rice cracker bursts in the steam path, reduces the penetration of the rice cake into the air blowing path, and reduces the frequency of cleaning the air blowing path. It makes it possible to provide a good rice cooker.

  Note that the snagging unit 22 may have a structure in which it is difficult to reach the stirrer to the blower path 14. For example, at least a part of the wall surface of the steam path 15 is cooled and the nebula comes into contact with the wall surface. Other means such as a rupture of a film-like rice cake may be used.

  In addition, if a pressure valve is provided immediately above the steam hole 4a, it is only necessary to reduce the entry of the rice ball into the blowing path 14. In that case, the height of the lid body 3 can be reduced by not disposing the pressure valve portion under the blower path 14, and a compact rice cooker can be obtained.

  In addition, as shown in FIG. 7, the toughness inhibiting part 22 has a magnet 28a that can be moved in the direction of the arrow F in FIG. It is good also as a structure which provides the magnet holder 28b which supports 28a, and the magnetic force detection part 28c which can detect whether it exists in the position when the magnet 28a does not come to the outer side of the vapor | steam path | route 15. In this case, when the magnet 28a is not in a predetermined position by the magnetic force detection unit 28c, the control device 7 determines that the rice cake has passed through the magnet 28a portion, and controls the pan heating device 5 to reduce the heating amount of the pan 2. It is possible to suppress the occurrence of the begging itself. In this configuration, generally, since it does not enter after the magnet 28a portion in the steam path 15, cleaning may be easy. In addition, if the magnet 28a and the magnet holder 28b are detachably provided, cleaning may be easy.

(Embodiment 4)
FIG. 8 shows a rice cooker according to Embodiment 4 of the present invention. The same components as those in the first and second embodiments are denoted by the same reference numerals and the description thereof is omitted.

  As shown in the figure, the rice blocker inhibiting portion of the rice cooker in the present embodiment is an air blowing guiding portion 23 formed of a rib for introducing a part of the wind generated by the air blowing device 11 into the steam path 15. The air blowing guide unit 23 is opposed to the wind flow of the air blowing device 11 and has a shape rising in the steam path 15.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When the air blower 11 is operated, a wind as shown by B in the figure is generated. However, the presence of the air blowing guide 23 causes a part of the wind from the air blower 11 to move in the direction indicated by the arrow B2. Into the steam path 15. Thereby, cold wind hits the film-like rice cake which moves with steam during the cooking process, and the rice cake bursts.

  With the above configuration, the rice cooker of the present embodiment can rupture the rice ball more effectively in the steam path, so that the rice powder can be reduced from entering the air supply path, and the air supply path. This makes it possible to provide an easy-to-use rice cooker that does not require washing.

  In addition, by providing a return path to return the rice balls remaining in the steam path 15 to the pot 2 from the steam port 4a, the rice balls will reattach to the rice in the pot 2 and the gloss of the rice will improve. Good.

  Further, when the wind from the blower 11 is guided to the steam path 15, the film-like rice cake can be ruptured, but the risk of the wind entering the pot 2 increases, so the steam path outlet of the steam path 15 A metal part with good heat conduction such as aluminum is fixed near 15b, one end of the metal part is exposed in the blower passage 14, the metal part is cooled by the wind from the blower 11, and the whole metal part is cooled by heat conduction. When the rice cake moves along with the steam in the steam path 15, this metal part comes into contact with the rice cake, so that the film-like rice cake is ruptured. The fear that air may enter the pot 2 may be reduced.

(Embodiment 5)
9-11 has shown the rice cooker in Embodiment 5 of this invention. The same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 9, the rice cooker in this Embodiment provided the exhaust direction control part 24 which discharges | emits the mixture of the air by the air blower 11, and the vapor | steam from the vapor | steam path | route 15 diagonally ahead of the rice cooker main body 1. As shown in FIG. Is.

  In the present embodiment, the air blower 11 is arranged not on the air passage 14 and the hinge shaft 3a but on the left side of the rear portion of the lid body 3. The intake port 12 is provided on the left side, which is the intake side of the blower 11, and includes a plurality of holes provided on the side surface of the lid body 3. The exhaust port 13 is provided on the right side, which is the exhaust side of the blower device 11, so as to face the blower device 11, and includes a plurality of holes provided on the side surface of the lid body 3. Both the intake port 12 and the exhaust port 13 are slit-shaped holes. The air blowing path 14 has a substantially straight shape and a substantially uniform cross-sectional area.

  The exhaust direction restricting portion 24 is provided in the vicinity of the exhaust port 13 and guides the wind from the blower 11 in the forward direction and the shielding wall 24a for blocking the wind from the blower 11 and changing the direction. The exhaust path front extension wall 24b and the slit wall 24c oriented in an oblique direction that guides the direction of the slit hole of the exhaust port 13 in a desired direction.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. By providing the intake port 12 and the exhaust port 13 on the side surface of the rice cooker body 1, even if liquid or the like is accidentally dropped from above the lid body 3, the liquid or the like that has fallen into the blowing path 14 enters and enters the blowing device 11. The adhesion of liquid or the like can be reduced.

  Further, when the lid body 3 is opened in a state where condensation is formed in the air passage 14 during the heat insulation, if the air blower 11 is disposed between the air passage 14 and the hinge shaft 3a, the dew condensation water is transferred to the air blower 11. It may adhere and cause a failure of the blower 11. However, since the blower 11 is disposed on the left side of the rear portion of the lid main body 3, it is possible to reduce the condensation in the blower passage 14 from adhering to the blower 11 even when the lid main body 3 is opened.

  As shown in FIG. 1 and FIG. 2, if the exhaust port 13 is in the approximate center of the lid body 3 and the exhaust direction is obliquely upward, the remaining rice cooking time during the operation of the blower 11 during cooking by the user If you get close to the rice cooker to check the cooking course, etc., it may not feel hot even if you touch it, but it may blow off the front of the user's body such as the face and feel uncomfortable, In this embodiment, exhausting diagonally forward as indicated by arrow B in FIG. 9 enables exhaust without causing such discomfort.

  In addition, when rice cooker main body 1 is accommodated in a shelf as shown in C in FIG. 9 and rice cooking is performed, for example, when exhausted in the blowing direction indicated by arrow B in FIG. It stays in the shelf C, the ambient temperature around the rice cooker main body 1 rises, the high-temperature gas moves to the surroundings of the control device 7, the temperature of parts on the control device 7 rises, and the operation begins. In this embodiment, when exhausted in the direction indicated by the arrow B in FIG. 9, the outside of the shelf C along the side wall of the shelf C as indicated by the arrow B3 in FIG. Is less likely to stay in the shelf C, and adverse effects on the control device 7 can be reduced.

  With the above configuration, the rice cooker of the present embodiment stores the rice cooker body in the shelf while reducing the direct exhaust to the user when standing in front of the rice cooker body. Even when rice cooking is performed, it is possible to provide a highly reliable rice cooker that can stably cook rice without causing exhaust gas to stay in the shelf.

  If the exhaust port 13 is on the side surface, it is less likely to directly hit the user's face even if the exhaust direction is obliquely upward or upward.

  In addition, if the slit wall 24c is arranged in a sufficiently long shape as compared with FIG. 9 between the exhaust port 13 and the steam path outlet 15b in the blower path 14, the pressure loss is further reduced and the exhaust direction is also directed forward. It is good because it becomes possible.

  Further, as shown in FIGS. 10 and 11, an exhaust direction variable unit 25 that changes the discharge direction of the mixture of the air and the steam from the steam path 15 by the blower 11 may be provided. The exhaust direction variable portion 25 includes a knob 25a that is a handle that is slid by the user to change the exhaust direction, and a shielding plate portion 25b that moves in and out of the air passage 14 to change the direction of the exhaust. .

In this case, the user can change the exhaust direction by operating the knob 25a of the exhaust direction variable unit 25 to slide the shield plate portion 25b. That is, as shown in FIG. 10, by sliding the knob 25 a to the front side of the rice cooker body 1 from the state where the shielding plate portion 25 b is housed in a place where the direction of air blowing indicated by the arrow B is not hindered, FIG. As shown in FIG. 4, the shielding plate portion 25b moves to a place where airflow is blocked and changes the direction of airflow to change the exhaust direction in the direction of arrow B. Thereby, when a user cooks rice in a shelf, it should be in the state of FIG. 11, and if there is no wall around the rice cooker, the user should be exhausted in the side direction of the rice cooker body, which is difficult to blow. The exhaust direction can be changed for the convenience of the user, such as exhausting in the state of FIG. 10, and a convenient rice cooker can be provided.

  Moreover, as shown in FIG. 11, when the shielding plate portion 25b is closed, the exhaust area of the exhaust port 13 is reduced, the flow rate of the exhaust body is increased, and when the rice is cooked in the shelf, the exhaust body is more of the shelf. It will be easier to go outside.

  In addition, when the knob 25a and the shielding board part 25b which comprise the exhaust direction variable part 25 are provided and only changing the flow rate of exhaust gas without changing the exhaust direction and cooking rice in a shelf, the flow rate is increased and the shelf In the case of expelling the exhaust body from the inside and cooking rice in an open space, it may be a variable means for adjusting the exhaust concentration to reduce unpleasant winds such as slowing the flow velocity and hitting the user's face.

  The direction of the exhaust may be changed in the vertical direction of the rice cooker body, or may be selected not only in the horizontal direction but also in the backward direction.

  In order to prevent the user from feeling the momentum of air blowing, the hole cross-sectional area of the exhaust port 13 is made larger than the air volume even when exhausting diagonally upward of the rice cooker as shown in FIGS. If it is ensured and the wind speed at the exhaust port 13 is lowered, the wind may not easily reach the user.

(Embodiment 6)
12 and 13 show a rice cooker according to Embodiment 6 of the present invention. The same components as those in the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  As shown in FIG. 12, the rice cooker in the present embodiment is provided with a plate-like vapor diffusion rib 26 that uniformly mixes the air from the blower 11 and the vapor from the vapor passage 15 in the blower passage 14. It is. At least one vapor diffusion rib 26 is provided on the exhaust port 13 side in the vicinity of the vapor path outlet 15b, and the steam that has entered the blower path 14 is prevented from flowing immediately to the exhaust port 13 to be uniform with the blown air. To be mixed.

  As shown in FIG. 13, the steam diffusion rib 26 is a rib having a shape that is higher in the vicinity of the steam path outlet 15 b and lower as it is away from the steam path outlet 15 b. It is good also as a shape which is discharged | emitted as a mixture with which vapor | steam and air were mixed substantially uniformly in the exhaust port 13 at the exhaust port 13.

  In the present embodiment, the steam path 15 is connected to the blower path 14 vertically.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. The steam that has moved to the blowing path 14 during rice cooking is provided at a position where the steam path outlet 15b is biased (the position of the blowing path 14 in front of the rice cooker body 1). When the air is blown away by the air from the blower 11 just above 15b and is exhausted from the exhaust port 13, it is not mixed well. Therefore, the steam in the front portion of the rice cooker body 1 is heated at high temperature, and the exhaust gas in the backward direction is cooled at low temperature, and the steam is discharged when the user holds his / her hand over the exhaust. However, by providing the vapor diffusion ribs 26, the mixture is uniformly mixed in the air blowing path 14, and the temperature of the exhaust body from the exhaust port 13 becomes uniform.

  With the above configuration, the rice cooker of the present embodiment is uniform by providing a steam diffusion rib even when the mixing degree of steam and air in the air blowing path is uneven due to the position of the steam path outlet. It becomes possible to mix, and it becomes possible to provide the rice cooker with a high steam processing function which can reduce the temperature of discharge | emission steam | vapor.

  The vapor diffusion rib 26 may not be a rib as in the present embodiment, but may have a structure such as a rapid expansion or reduction of the cross-sectional area in the path shape, or other means such as blowing with a blower from another direction. May be used.

(Embodiment 7)
FIG. 14 shows a rice cooker according to Embodiment 7 of the present invention. The same components as those in the first and second embodiments are denoted by the same reference numerals and the description thereof is omitted.

  As shown in the figure, the rice cooker in the present embodiment is provided with a drainage path 27 having a groove shape in which water is floated without contacting the blower 11 in the blower path 14. An intake passage 28 is provided between the blower 11 and the intake port 12, and the internal space of the intake passage 28 and the space in the lid body 3 are not connected. Further, the inlet 12 is provided only at a position lower than the blower 11.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. In the cooking process, as described above, condensation occurs in the air blowing path 14. In addition, when the user accidentally cooks rice with a larger amount of water than usual, the water in the pan 2 may overflow to the blower path 14 through the steam path 15. In this way, when water is generated in the air passage 14, the water moves to the intake passage 28 through the drainage passage 27 without contacting the blower 11, and enters the lid body 3 along the intake passage bottom surface 28 a. Without being discharged from the air inlet 12 to the outside of the lid body 3.

  Further, even if the user mistakenly inputs water from the intake port 12 or water is condensed on the intake port 12, the blower 11 is not connected to the intake port 12 even if water enters the intake path from the intake port 12. The possibility of water contact is very low.

  With the above configuration, the rice cooker of the present embodiment can discharge water outside the lid body without bringing water into contact with the blower or the inner lid heating device even during abnormal use where rice is cooked with an abnormally large amount of water. Even if there is abnormal use, it is possible to reduce the failure of the blower. Moreover, even when water enters from the intake port, the failure of the blower can be reduced.

  The guide rib 27b is configured not to discharge the dropped water immediately from the intake port 12, but to store a small amount in the lid body 3 and to discharge the overflow amount from the intake port 12. Since the stored water is dried until the next rice cooking, if only a little water is generated due to condensation or the like in the air blowing path 14, there is no need for cleaning, and thus a convenient rice cooker can be provided. it can. The guide rib 27b has such a shape that a small amount of water stored in the lid body 3 does not move to the inner lid heating device 10 side even when the lid body 3 opens to about 90 degrees with respect to the rice cooker body 1. It needs to be.

In addition, although the water discharged | emitted from the inlet 12 may be transmitted to the outer surface of the lid body 3 and further transmitted to the floor through the outer surface of the rice cooker body 1, the user moves the rice cooker and cleans the floor. Therefore, if the water discharged to the outside of the lid main body 3 is transmitted to the outer surface of the lid main body 3 and collected in the upper frame water reservoir 1f in FIG. 14, the rice cooker main body 1 is collected without moving. Easy to use because water can be removed.

(Embodiment 8)
FIG. 15 shows a rice cooker according to the eighth embodiment of the present invention. The same components as those in the first and second embodiments are denoted by the same reference numerals and the description thereof is omitted.

  As shown in the figure, in the rice cooker in the present embodiment, a steam path outlet 15b is formed almost immediately above the steam path inlet 15c, and has four 90-degree bent shapes therebetween. Further, the steam path outlet 15b is connected substantially vertically to the air blowing path 14, and is also configured to be connected vertically to the flow of wind passing through the air blowing path 14.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. When the pan 2 is heated intermittently in the cooking process, the wind from the blower 11 enters the steam path 15 when the heating is stopped. However, since the wind speed decreases while passing through the plurality of bent portions and the heating stop time is 1 second to several seconds, the air does not reach the inside of the pot 2. When the heating is resumed, the boiling is resumed, so that the wind is also pushed out to the blowing path 14.

  With the above configuration, the rice cooker of the present embodiment reduces the steam temperature to be discharged, and even when the wind from the blower enters the steam path, the wind intrudes into the pot by the wind intrusion prevention unit. The steam temperature reduction function that reduces the inhibition of gelatinization that occurs when air at room temperature intrudes into a pan of about 100 ° C and lowers the temperature in the pan, improving the rice cooking performance. It becomes possible to provide a rice cooker.

  In the present embodiment, the steam path 15 itself is connected perpendicularly to the blower path 14, but the steam and the steam are mixed substantially perpendicularly to the air. Since the purpose is to mix uniformly, it is not always necessary to connect the steam path 15 perpendicularly to the blower path 14, and the steam path 15 and the blower path 14 are connected in parallel, as shown in the sixth embodiment. Even if the steam is moved in a direction perpendicular to the air in the air blowing path 14 by the rib such as the steam diffusion rib 26, the same effect may be obtained.

(Embodiment 9)
FIG. 16 shows a rice cooker according to Embodiment 9 of the present invention. The same components as those in the first to eighth embodiments are denoted by the same reference numerals, and the description thereof is omitted.

  As shown in the figure, in the rice cooker in the present embodiment, the steam path 15 is connected to the lower part of the substantially vertical path wall 14b farthest from the hinge shaft 3a of the blower path 14. The ventilation path 14 is configured to be detachable, and can be removed in a direction indicated by an arrow E in the drawing, that is, a direction of sliding backward, and can be mounted in the reverse direction. Since the connection part of the ventilation path 14, the vapor | steam path | route 15, and the air blower 11 exists in the lower side of the lid main body top surface 3b, and becomes the structure which is not exposed outside, it is comprised so that dust and dust do not collect easily. Further, a portion other than the vicinity of the exhaust port 13 of the air blowing path 14 is also configured in the lid main body 3. Further, the steam path 15 can be removed in the direction indicated by the arrow F in the figure, and can be mounted in the reverse direction. When both the air blowing path 14 and the steam path 15 are mounted, the internal spaces of the both are configured to be connected to each other, and the steam in the pan 2 is inside the steam path 15 and inside the exhaust path 14. The exhaust gas is exhausted from the exhaust port 13 and the steam does not leak into other spaces such as the inside of the lid body 3. The exhaust port 13 is provided to be inclined obliquely upward on the hinge shaft side of the blower passage 14, and the exhaust steam is exhausted obliquely upward as indicated by an arrow G in the figure.

  About the rice cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  Since the basic operation is the same as that of the first embodiment, a description thereof will be omitted. Even when the lid body 3 is opened while condensation is generated in the air passage 14 during the heat insulation, almost all the condensed water in the air passage 14 moves to the hinge shaft 3a side, so the condensed water enters the steam passage 15. There is almost nothing. Moreover, since it has connected below the substantially vertical path | route wall 14b, the vapor | steam which entered into the ventilation path 14 from the steam path 15 during rice cooking tends to move lightly upwards rather than air, and is easy to mix with air more uniformly.

  When the dew condensation occurs in the air blowing path 14 or the user cooks rice with an incorrect amount of water, sticky water in which water, rice starch or the like has melted from the pan 2 may enter. In such a case, the blower path 14 can be attached and removed for cleaning, but if the blower path 14 is exposed to the outside of the lid body 3, it is a connection part with other parts (for example, the blower 11 and the steam path 15). (For example, near the steam path outlet 14b or near the exhaust side 11b of the blower 11), dust and dirt can easily enter, and repeated attachment and detachment causes dust and dirt to enter the blower path 14, causing dust and dirt to enter the room. Although it winds up, according to the structure of this Embodiment, since it is comprised in the cover main body 3 except the exhaust port 13 vicinity of the ventilation path 14, dust and dust do not enter into the ventilation path 14. Moreover, if the connection part of the ventilation path 14 and other components is exposed to the outside, when the ventilation path 14 is removed, a foreign object falls to the vicinity of the connection part, and when the ventilation path 14 is mounted without being noticed by the user, It becomes impossible to seal the connection part, and high-temperature steam leaks out, and high-temperature steam leaks from parts other than the exhaust port 13, but the connection part between the blower path 14 and other parts is on the top surface 3 b of the lid body. Since it arrange | positions below, it can reduce that a foreign material falls to a connection part.

  The steam path 15 is in a removable state when the lid body 3 is opened and the inner lid 4 is removed. Viscous water from which water or starch of rice has melted may adhere to the inside of the steam path 15, so that it can be easily washed if it can be attached and detached. However, if the blower path 14 and the steam path 15 are removed together, it becomes a very long part in the front-rear direction of the rice cooker body 1, and it becomes difficult to pull out by sliding, but in this embodiment, the steam path 15 Can be attached and detached separately from the air blowing path 14, so both can be easily attached and detached.

  Moreover, although the control apparatus 7 operates the air blower 11 when a lot of steam goes out during rice cooking, it continues air blowing for a fixed time after rice cooking. Thereby, even in the steaming process in which a large amount of steam is not emitted, even if the hot and humid air in the pan 2 gradually flows into the blowing path 14, the hot and humid air in the blowing path 14 is replaced with the outside air, so that the blowing path 14 can reduce the occurrence of condensation.

  With the above configuration, it is possible to reduce the condensation in the air blowing path from entering the steam path and dripping into the pan to make the heat-insulating rice tasteless. In addition, the connection part with the steam path is arranged below the top surface of the lid body, and the ventilation path is configured to be slidable and detachable to the rear, so that foreign matter is caught between the connection parts and steam leakage occurs, and the user can The risk of burns can be reduced. Moreover, attachment and detachment becomes easy by being able to attach or detach a vapor | steam path | route separately from a ventilation path | route. Furthermore, it can reduce that the inside of a ventilation path | route becomes a hot and humid environment by operating a ventilation apparatus even after rice cooking.

  In addition, if the control apparatus 7 is operated for a certain period of time at a fixed time interval even during the heat insulation, it may be possible to further reduce the high temperature and humidity environment in the air blowing path.

  In addition, the control apparatus 7 may operate | move after stopping operation | movement of the air blower 11 once during rice cooking, and entering into heat insulation.

In addition, a rice cooker is provided with a room temperature detection part (not shown), and the control apparatus 7 is the air blower 1 according to room temperature.
If the operation timing and the operation time of 1 are changed, the dew condensation in the air blowing path 14 can be further reduced.

  In each of the above-described first to ninth embodiments, the display unit 18 is disposed on the substantially flat surface of the front portion of the lid body 3. However, as shown in FIG. Even if you look at the rice cooker from a little distant place, you can easily check the display unit 18 and check the remaining rice cooking time, etc., and the convenience is improved. In this case, the operation buttons 19 may be similarly arranged on the inclined surface, may be arranged on a substantially flat surface, or may be arranged apart from the display unit 18. Further, the display unit 18 may not be in the lid body 3 but may be in another place such as the front surface in the rice cooker body 1.

  In each of the above-described first to ninth embodiments, the steam path 15 is connected to the blower path 14, but the steam path 15 is connected to the intake side 11a and the intake port 12 of the blower 11 as shown in FIG. If it is connected to the intake passage 28 formed between the air and the steam, the air and steam are sufficiently uniformly mixed by the blower 11 so that the exhaust steam temperature is further reduced. When the steam path 15 is connected to a path formed between the intake side 11a of the blower 11 and the intake port 12, the steam discharged from the steam path 15 does not enter the inside of the lid body 3. In addition, the intake passage 28 hermetically connects the intake side 11 a of the blower 11 and the intake port 12.

  As described above, the rice cooker according to the present invention is capable of coexisting cooking delicious rice and lowering the temperature of discharged steam by sufficiently mixing steam and air. Applicable to. Moreover, it is applicable also to the use of the cooking appliance which has another rice cooking function.
