Description

[Detailed description of the invention] Industrial application field The present invention heat-exchanges steam generated during rice cooking,
This invention relates to a rice cooker equipped with a steam condensing device that exhausts air as low-temperature, low-humidity air.

Configuration of conventional example and its problems Conventional rice cooking devices exhaust a large amount of steam during rice cooking. Due to the high temperature and high humidity of the steam, a large amount of moisture was trapped inside the room, condensing on the walls, etc., making it very uncomfortable to use.

Furthermore, the steam discharged is at a high temperature, and if a user accidentally touches it, there is a danger of burns, etc., and there is also a safety problem.

Purpose of the Invention The present invention was made to solve the above-mentioned conventional problems, and by adding a steam condensing device to a conventional rice cooking device, the steam discharged from the rice cooking device is converted into low-temperature, low-humidity air. The purpose is to discharge.

Structure of the Invention The present invention comprises a rice cooker, a steam condensing device, and a steam guide extending from the steam condensing device, one end of which is formed of a flexible material, and the steam guide provided in the rice cooker By facing and abutting against the holes, only the hot and humid steam discharged from the rice cooker is reliably guided to the steam condensing device.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. 1 is the main body of the rice cooker. Reference numeral 2 denotes a drawer disposed at the front of the main body 1, and a rice cooker 3 is detachably disposed in the drawer 2. 4 is a power switch arranged on the front side of the main body 1. Reference numeral 5 denotes a steam condensing device provided within the main body 1. One end of the steam condensing device 5 serves as an exhaust port 6 opened on the front surface of the main body, and the other end serves as a drain port 7 for condensed water. 8 is a steam inlet provided in the steam condensing device 5. 9 is a steam hole provided in the lid 10 of the rice cooker 3. A steam guide 11 is open at both ends, and one end 12 is made of a flexible material and is brought into contact with the steam hole 9 at a position opposite to the steam guide. Further, the other end is connected to the steam inlet 8 of the steam condensing device 5. Reference numeral 13 denotes a water supply tank, which is disposed within the main body 1 above the steam condensing device 5. Water is appropriately supplied to this from a water supply pipe 15 provided with a water supply valve 14. The water supply pipe 15 is connected to a water supply source (not shown) such as water supply. Reference numeral 16 denotes a cooling pipe, which is spirally wound inside the steam condensing device 5 in order to increase the heat exchange area, and one end 17 is connected to the lower part of the water supply tank 13 via a solenoid valve 18. , the other end 19 is connected to a drain pipe 20. And the drain pipe 20 is
It is connected to sewage etc. (not shown). Reference numeral 21 denotes a drain pipe that communicates the drain port 7 for condensed water of the steam condensing device 5 with the drain pipe 20 . 22 is a float switch that controls the water supply valve so as to keep the water level in the water supply tank 13 constant.

The operation of the rice cooking device configured as above will be explained. First, after putting rice and water into the rice cooker 3, set the rice cooker 3 in the drawer 2. Next, when the power switch 4 is turned on, rice cooking starts, and after a certain period of time, the solenoid valve 18 is activated, and the water in the water tank 13 flows through the cooling pipe 16 and is drained through the drain pipe 20 into the sewer or the like. The steam released from the steam hole 9 passes through the steam guide 11 and is guided into the steam condensing device 5, where it comes into contact with the cooling pipe 16, so that heat is generated between it and the water flowing inside the cooling pipe 16. When the cooling pipe 16 is replaced, dew condenses on the surface of the cooling pipe 16, resulting in low temperature.
The air becomes low-humidity and is exhausted from the exhaust port 6. At this time, one end 12 of the steam guide 11 made of a flexible material is in contact with the steam hole 9 provided in the rice cooker 3, so air is mixed in and the heat exchange efficiency is reduced due to a tunnel effect or the like. It will not be significantly reduced. Therefore, inside the steam condensing device 5,
Only condensable steam is introduced, and the heat exchange efficiency is extremely high, so the heat exchange area can be made small and the amount of cooling water can be reduced. In addition, the condensed water is drained from the drain port 7 to the drain pipe 21 and the drain pipe 20.
It is discharged to sewage etc. through. When rice cooking is finished and steam is no longer released, the solenoid valve 18 stops operating. Also, when the drawer 2 is moved back and forth to take out and put in the rice cooker 3, one end 12 of the steam guide 11 is made of a flexible material and is arranged so as to come into contact with the rice cooker 3. Therefore, there will be no gap here.

Effects of the Invention As described above, the present invention adds a steam condensing device to a rice cooker, and by forming one end of the steam guide with a flexible material, the steam is discharged from the steam hole provided in the rice cooker. It is possible to introduce only the hot and humid steam into the steam condensing device without mixing with outside air. Therefore, since hot and humid steam is not discharged, the room does not become damp, and there is no risk of accidental burns to the user.

Furthermore, since non-condensable outside air does not enter the steam condensing device, it is possible to provide an excellent rice cooking device that has extremely high heat exchange efficiency, is small and lightweight, and requires only a small amount of cooling water.
