The operation of the built-in type rice cooker configured as described above will be described below. When a power switch (not shown) is turned on, the heating means 14 starts the rice cooking operation, and a large amount of steam is generated from the rice cooking section 12 and discharged from the steam port 16. This steam is collected by the steam collecting fan 18 through the collecting pipe 17. The collected water vapor is exhausted toward the heat exchange pipe 21 a forming the heat exchanger 21. On the other hand, the fins 21b of the heat exchanger 21 are cooled by the cooling fan 22 by the cooling air by the low temperature air outside the machine sucked from the cooling duct 22a arranged below the rice cooking unit 12. In this way, heat is exchanged in the heat exchanger 21, and the steam that has flowed into the heat exchange pipe 21a is cooled and a part thereof is condensed, condensed and dehumidified. The steam dehumidified in this way is discharged into the steam path 24. Condensed water that has condensed at the same time is the heat exchange pipe 21a.
It flows inside and is drained through the drainage pipe 27. The dehumidified steam flows in the steam path 24 and
Guided by the side wall 24b, the direction of the exhaust port 20 is changed to the approximate center. The steam that has been redirected flows out to the connection port 25 and cools the fins 21b.
Exhaled in the cooling air flowing inside. In this case, the dehumidified steam is guided by the guide vanes 26 from the steam path 24 to the center of the exhaust path 23. The water vapor dehumidified in this way is discharged almost at the center of the cooling air flowing through the exhaust path 23, and therefore is very efficiently and evenly mixed with the cooling air. The air mixed here is exhausted from the exhaust port 20. The exhaust air has a very low moisture content due to dehumidification by heat exchange and mixing with cooling air. For this reason, even if the vehicle is operated at a low temperature such as condensation in the room or in the winter, the exhaust does not whiten.

As described above, according to this embodiment, the steam discharged from the steam port 16 of the built-in type rice cooker is collected,
Part of the heat is exchanged in the heat exchanger 21 to cause dew condensation and dehumidification.
At the same time, the dehumidified exhaust gas that has exited the heat exchanger 21 is mixed with the cooling air to further reduce the humidity and then discharged, so that an uncomfortable situation such as dew condensation in the room or whitening of the exhaust gas can be prevented.

Further, since the cooling air is sucked from the cooling duct 22a, a low temperature cooling air can be obtained and the dehumidifying performance can be further improved.

Further, since the steam path 24 is formed above the exhaust path 23, the exhaust containing the steam after the heat exchange is guided to the exhaust path 23, so that the retention can be prevented.

Further, since the guide vanes 26 are provided, the exhaust gas containing the steam can be better mixed into the cooling air, and the whitening of the exhaust gas can be prevented more effectively.

The side wall 24b of the steam path 24 is connected to the exhaust port 2
By forming the exhaust gas so as to guide the exhaust gas toward the approximate center of 0, the exhaust gas containing the vapor can be discharged toward the approximate center of the cooling air, preventing the mixture from being offset in the width direction. It is possible to further prevent whitening of the exhaust gas.

Further, since the heat exchanger 21 is set to be inclined, the water condensed in the heat exchanger 21 can be discharged, stable heat exchange can be performed, and dehumidifying performance can be maintained. ..

[0027]

As described above, according to the first means of the present invention, since the dehumidified exhaust gas is mixed with the cooling air to be processed,
The amount of steam discharged to the outside can be reduced, and an uncomfortable situation such as dew condensation in the room or whitening of exhaust gas can be prevented.

According to the second means of the present invention, since the cooling duct is connected to the intake side of the cooling fan to obtain the low-temperature cooling air, it is possible to realize an apparatus having further improved dehumidification performance. It is possible.

Further, according to the third means of the present invention, since the steam path is formed above the exhaust path, the exhaust containing the steam after the heat exchange is guided to the exhaust path and is prevented from staying in the steam path. It is possible to obtain a device having excellent durability.

Further, according to the fourth means of the present invention, by providing guide vanes for guiding the dehumidified steam into the exhaust path at the connection port between the steam path and the exhaust path, the exhaust containing the steam can be discharged. It is possible to mix better in the cooling air and to perform the steam treatment more reliably.

Further, according to the fifth means of the present invention, the side wall of the steam path is formed so as to guide the exhaust gas toward the substantially center of the exhaust port, so that the exhaust gas containing the steam can be substantially contained in the cooling air. It is possible to discharge toward the center, prevent the biased mixing in the width direction, prevent whitening of the exhaust more, and eliminate dew condensation in the vicinity of the outer periphery of the exhaust port.

Further, according to the sixth means of the present invention, by arranging the heat exchanger in an inclined manner, it is possible to easily discharge the condensed water generated in the heat exchanger. In addition, it is possible to perform more efficient steam treatment.
