Further, an exhaust port 9 is provided at the upper rear surface of the rice cooker storage 5, an exhaust passage 10 is provided at the rear surface of the main body 1, and an exhaust port 11 is provided above the exhaust passage 10. .

The operation of the rice cooking device configured as described above will be explained below. When rice and water are put in the rice cooker 3 and the rice cooker 3 is heated by the heating device 2 to cook rice, steam comes out from the gap between the lid 4 and the rice cooker 3 into the rice cooker storage 5. The steam filling the rice cooker storage 5 is discharged from the exhaust port 8 and the exhaust port 9. The steam discharged from the exhaust port 9 passes through the exhaust passage 10 and is discharged to the outside of the main body 1 from the exhaust port 11.

However, the above configuration has the problem that high temperature and high humidity steam is discharged indoors, so a large amount of moisture stays indoors as humidity, and furthermore, dew condenses on walls and the like.

In addition, the steam being exhausted is at a high temperature, so there is a risk of burns if the user accidentally touches it.
Therefore, there were also safety issues. Furthermore, there was also a problem in that steam condensed on the inner wall of the rice cooker storage 5 and the inner wall of the opening/closing door 6, causing water droplets to adhere and corrosion.

Further, the drawer portion 25 is provided with an outlet 27, and the outlet 27 is connected to an AC power source (not shown) via a power cord 28. The rice cooker 21 includes a first rice cooking lamp 29 that lights up when cooking rice, and a first warming lamp 30 that lights up when keeping rice warm.
has been established. On the other hand, a second rice cooking lamp 31 and a second warming lamp 32 are provided at the front of the main body 20.
is provided, and a first rice cooking lamp 29 and a first rice cooking lamp 29 are provided.
The second rice cooking lamp 31 and the second heat retention lamp 32 display the cooking status to the outside according to signals from a rice cooking detection sensor 33 and a heat retention detection sensor 34 provided at positions facing the heat retention lamp 30. Further, an exhaust passage 35 having an intake port 38 and an exhaust port 36 at both ends is provided at the upper part of the rice cooker 21 located inside the storage of the main body 20, and the exhaust port 36 is connected to the display panel 37. It is open to A fan motor 40 equipped with a fan 39 as a ventilation means is disposed near the intake port 38 side of the exhaust passage 35. A partition plate 41 is provided in the exhaust passage 35 to divide the exhaust passage 35 into an air passage A and a steam passage B. Between the exhaust port side end of the partition plate 41 and the exhaust port 36, an air passage is provided. A mixing chamber C is provided where A and steam passage B merge. Further, the steam passage B is provided with a steam inflow hole 42 and has a steam guide 43 formed of a flexible material, and this steam guide 43 is connected to the rice cooker 2.
1 steam hole 24 and the steam inflow hole 42 are connected, and the steam generated during rice cooking is guided to the steam passage B through the space D in the steam guide 43. Also, below the steam passage B is a condensed water receiver 44.
This condensed water receiver 44 is provided with a drainage hole 45.
and a dew pan 46 below this drainage hole 45.
is detachable.

The operation of the rice cooking device configured as above will be described below. First, rice cooker 2
1 is mounted on the drawer section 25. At this time, the legs 23 of the rice cooker 21 fit into the grooves 26, so the rice cooker 21 is installed at a predetermined position. Next, connect the power plug 22 to the outlet 27, and
is closed and the rice cooker 21 is housed inside the main body 1 of the apparatus.
At this time, the first rice cooking lamp 29 and the rice cooking detection sensor 33 and the first heat retention lamp 30 and the heat retention detection sensor 34 face each other, and the steam vent 24 of the rice cooker 21 faces the steam guide 43.

When the rice cooker 21 is in the rice cooking state, the first rice cooking lamp 29 lights up, and this light is transmitted to the rice cooking detection sensor 3.
3 is sensed, the second rice cooking lamp 31 is turned on, and the fan motor 40 is driven. The air blown by this drive is then transported to the air passage A.
and flows through the mixing chamber C and is discharged to the outside from the exhaust port 36. Further, steam discharged from the steam hole 24 of the rice cooker 21 passes through the air D in the steam guide 43 and flows into the steam passage A from the steam inflow hole 42.
In this case, the presence of the partition plate 41 can prevent steam from flowing back toward the steam inflow hole 42 side, allowing the steam to flow smoothly. In addition, since the partition plate 41 is made of a material with high thermal conductivity such as aluminum fins, the steam passage B
Heat exchange occurs between the steam flowing through the air passage A and the air flowing through the air passage A, and the steam is cooled and condensed within the steam passage B. And this condensed water is transferred to the condensed water receiver 4.
Water is stored in a dew tray 46 from a drainage hole 45 provided in 4. In addition, the steam flowing into the mixing chamber C from the steam passage B further mixes with the air flowing through the air passage A, so its temperature and humidity are further reduced.
It is discharged from 6.

Next, when the rice is cooked and the rice is kept warm, the amount of steam generated decreases. Then, the first heat retention lamp 30 lights up, and the heat retention detection sensor 34 senses this light, and the second heat retention lamp 32 lights up, and the drive of the fan motor 40 is stopped.

Effects of the Invention As is clear from the description of the embodiments described above, according to the present invention, the exhaust passage is separated by a partition plate formed of a material with high thermal conductivity, and the air passage through which air flows by the blowing means and the steam through which steam flows. A mixing chamber is provided between the exhaust port side end of the partition plate and the exhaust port, where the air passage and the steam passage merge, and the partition plate is made of a material with high thermal conductivity. Therefore, heat exchange occurs effectively between the steam flowing in the steam passage and the air flowing in the air passage, and the steam is cooled and condensed in the steam passage, and the high-temperature steam after condensation is mixed. Since it is further mixed with air inside the room and turned into low-temperature, low-humidity air that is discharged to the outside, there is no longer a large amount of moisture stuck inside the room and condensing on the walls. Furthermore, since the steam exhausted into the room is at a low temperature, there is no danger of burns or the like even if the user accidentally touches it, so it can be used safely. and again,
Since steam does not condense within the device body, corrosion of the device can also be prevented.
