2. Description of the Related Art A conventional rice cooking device of this type has a structure as disclosed in, for example, Japanese Utility Model Publication No. 57-53455.

That is, as shown in FIG. 4, the pot 2 is housed in the apparatus body 1, and the lid 3 that covers the upper portion of the apparatus body 1 is pivotally supported by the hinge 4 on one side surface of the apparatus body 1. The lid 3 includes
A steam passage chamber 5 for discharging the steam generated from the pan 2 to the outside of the apparatus main body 1 is provided.
The structure is such that it is discharged to the outside of the apparatus main body 1.

When rice and water are put in the pot 2 to heat the heating element 7 to cook rice, the water in the pot 2 boils and steam is generated. This steam passes through the steam passage chamber 5 and is discharged from the steam outlet hole 6.

Problems to be Solved by the Invention However, in such a structure, since the steam to be discharged is at a high temperature, there is a risk of burns if the user accidentally touches the steam. There was a problem. Further, since the steam is blown upwards, it is impossible to put other objects above the rice cooker, and a large space is required for cooking rice. In addition, the "oneba" that was generated when cooking rice overflowed and was not hygienic.

The present invention is intended to provide a sanitary rice cooker, which has the above-mentioned conventional problems and is highly safe and capable of treating a "bed" generated during rice cooker.

Means for Solving the Problems In order to solve the above problems, the present invention has an open upper surface,
An apparatus main body having a heating element at the bottom, and a pan placed on the heating element, and a lid body pivotally attached to a rear side edge of the apparatus main body to openably and closably open an upper opening of the apparatus main body. The main body of the apparatus is provided with an air passage having an air inlet and an air blowing means, and the inside of the lid is provided with an exhaust passage having a steam guide communicating with the pan, the front end of which is open to the outside as an outlet, and the inside of the lid is provided with a device main body. A soup receiving storage portion is provided which is formed by recessing a part of the upper frame provided at the upper part of the upper surface and has an upper surface opened so that the soup receiving storage portion is detachably accommodated in the vertical direction. A certain gap is provided between the drains at the bottom of the soup tray storage part, and a drain pipe whose end opens to the bottom of the main body of the device is connected to this drain, and a lid is attached to the rear bottom of the exhaust passage. There is a drainage hole that penetrates through the body and opens at the end above the bowl. And it is obtained by the structure of the rice cooking system.

Operation With the above configuration, the steam generated during rice cooking is guided to the exhaust passage in the lid body, mixed with the outside air supplied by the air blowing means, and becomes low temperature and is discharged from the outlet.

Also, if you cook rice with the amount of rice and water put in the pot wrong and the amount of water added is increased, a large amount of sticky water will flow out from the steam guide to the exhaust passage. The spilled "Oneba" drips along the bottom of the exhaust passage from the drain port and is stored in the soup tray. If the amount of Onba is greater than the capacity of the soup tray and overflows from the soup tray, it falls between the soup tray storage section and the soup tray, collects the drainage pipe from the water outlet and collects in the saucer. It can be easily discarded by removing the saucer from the cabinet.

Next, the operation of the rice cooker thus configured will be described.

First, the pot 14 containing rice and water is placed on the heating element 13 in the inner pot housing portion of the device body 11, the device body 11 is covered with the lid body 19, and then the device body 11 is pushed into the cabinet 25. . At this time, the insect-proof packing 27 and the device body 11 come into contact with each other to exert an insect-proof effect. Next, when the switch operation unit 22 is turned on, the control circuit 24 energizes the heating element 13 and operates the blower unit 18. When the heating element 13 is heated, the water temperature of the pan 14 rises, and the generated steam is guided into the exhaust passage 32 through the steam holes 21a of the inner pan 21 and the steam guide 35 of the lid 19. On the other hand, the blower unit 18 sucks the outside air from the intake port 16 provided in the lower front portion of the apparatus main body 11 and generates the flow of air from the exhaust port 17 to the exhaust passage 32 via the air guide passage 37. Then, the air flowing through the exhaust passage 32 and the steam guided by the steam guide 35 are mixed to become low-temperature steam, which is discharged forward from the outlet 31. The steam that is discharged is of low temperature, so there is no risk of burns if touched.

As cooking rice progresses, the water in the pan 14 disappears and the temperature of the pan 14 rises sharply. And when the pot 14 temperature reaches a predetermined temperature,
The pan sensor 23 detects this, and the control circuit 24 controls the heating element B.
And, the power supply to the blower means 18 is stopped, and the rice cooking is completed.

After the rice is cooked, the apparatus main body 11 is pulled out to the front and the lid 19 is opened, so that the pan 14 is exposed and serving can be performed. At this time, since the lid body 19 is opened in the drawing-out direction of the apparatus main body 11, the lid body 19 does not become an obstacle when serving.
Further, the soup that had adhered to the inner surface of the lid 19 drops along the inner surface of the lid 19 when the lid 19 is opened, is collected by the soup guide 40, and flows out from the outlet 41 to the soup receiver 38 as it is. To be collected.

Further, when the rice and water to be put in the pan 14 are initially erroneous and the rice is cooked with a large amount of water added, a large amount of sticky water will flow out from the steam guide 35 in addition to the steam. The sleeper is accommodated in the bowl 38 from the drain 36 along the bottom of the exhaust passage 32. If the amount of the oneba is larger than the capacity of the soy sauce pan 38, the one that overflows from the soy sauce pan 38 will fall along the gap between the soy sauce pan storage part 39 and the sou sauce pan 38, and will be drained from the water outlet 42. Collected in the saucer 28 with a diameter of 43. Then, the saucer 28 can be taken out from the cabinet 25, and the collected ones can be easily discarded. In addition, the air duct 37 in the exhaust passage 32
Since the opening of is provided on the side wall in front of the drainage port 36,
When the lid 19 is opened, the door in the exhaust passage 32 is
It is not guided by 36 and does not enter the opening of the air duct 37.

By the way, when cleaning the exhaust passage 32 which is soiled with a stick, the exhaust passage 32 is exposed by opening the passage cover 33, which can be easily performed. At this time, since the hinge 34 of the passage cover 33 is located behind the exhaust passage 32, even if the device main body 11 is accidentally pushed into the cabinet 25 with the passage cover 33 opened, the passage cover 33 will still be on the top surface of the cabinet 25. Since the hinge 34 is closed by using the hinge 34 as a fulcrum, the passage cover 33 is not destroyed.

EFFECTS OF THE INVENTION As is apparent from the above description of the embodiments, according to the present invention, the steam generated during rice cooking is mixed with the outside air by the exhaust passage and the air blower provided in the lid of the rice cooking device to control the temperature. As low damp air can be dispersed outside the rice cooker body and exhausted, there is no risk of burns etc. even if the user accidentally touches the vicinity of the exhaust port, and by exhausting steam forward , The upper space of the rice cooker can be effectively used.

In particular, even if rice is cooked by mistakenly adjusting the amount of water added, the "oneba" discharged into the exhaust passage is once dropped from the drain port and collected in the sauce pan. When a larger amount of "Oneba" is discharged, it overflows from the soup tray, falls through the gap between the soup tray storage section and the soup tray, and is discharged to the outside of the main body. Since the soup is collected by the soup holder as well as the soup attached to the inner lid, the operability is greatly improved.
