Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice cooking device having a steam condensing function that heat-exchanges steam and exhausts it as low-temperature, low-humidity air.

Although conventional rice cooking devices exhaust a large amount of steam during rice cooking, no rice cooking device has been provided that has a device for condensing steam. As a result, high-temperature, high-humidity steam was directly exhausted into the room, and a large amount of moisture was released into the room, trapping moisture inside the room and condensing on the walls, making it very inconvenient to use. .

In addition, the steam released is at a high temperature, and there is a risk of burns if the user accidentally touches it, so there are safety issues.

The present invention solves the above-mentioned conventional drawbacks and condenses the steam generated during rice cooking by heat exchange and exhausts it as low-temperature, low-humidity air.

An embodiment of the present invention will be described below with reference to the drawings. 1 is the main body of the rice cooking device. 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 surface of the main body 1. 5 is a water tank, into which water flows from a water supply pipe 7 provided with a water supply valve 6. 8 is a drain valve for drainage 9
This is a drain pipe provided with a drain pipe, and one end communicates with a drain port 10 at the bottom of the water tank 5. Reference numeral 11 denotes an exhaust pipe made of a material with high thermal conductivity, which is disposed inside the water tank 5, and the portion that penetrates the wall of the water tank 5 is sealed with a sealing material 12. One end of the exhaust pipe 11 is opened at the front of the main body and serves as an exhaust port 13. 14 is a steam hole provided in the lid 15 of the rice cooker 3. Reference numeral 16 denotes a steam guide, one end 17 of which is disposed at a position facing the steam hole 14 and has three pages, and the other end communicates with the exhaust pipe 11. Reference numeral 18 denotes a condensed water drain pipe, which is made of a pipe having a diameter smaller than that of the exhaust pipe 11 to increase pipe resistance and prevent backflow of steam. 19
is a float switch that controls the water supply valve to keep the water level in the water tank constant. A fin 20 is disposed on the exhaust pipe 11 inside the water tank 5 to increase the heat transfer area.

The operation of the rice cooking device configured as above will be explained below. First, add rice and water, then set rice cooker 3 in drawer 2. Next, when the power switch 4 is turned on, rice cooking starts and the water supply valve 6 operates.
Water is injected into the water tank 5 and the exhaust pipe 11 and fins 20
is submerged.

As the rice cooking progresses, steam begins to be released from the steam vent 14. The steam flows through the steam guide 16 and the exhaust pipe 11 and reaches the exhaust port 1.
It is exhausted from 3. When the steam flows inside the exhaust pipe 11, heat exchange occurs between the water in the water tank 5 and the surface and fins of the exhaust pipe 11, so that the steam condenses and is exhausted from the exhaust port 13 as low-temperature, low-humidity air. The condensed water flows back inside the exhaust pipe 11 and is drained from the drain pipe 18. When rice cooking is finished and steam is no longer released, the drain valve 9 is operated and the water in the water tank is drained from the drain pipe 8.

As described above, according to the rice cooking device of the present invention, the exhaust pipe for exhausting steam generated during rice cooking to the outside of the main body is passed through the water tank, and the steam flowing inside the exhaust pipe is condensed and converted into low-temperature, low-humidity air. Since the air is exhausted, there is no possibility of moisture being trapped indoors, and there is no danger of burns, etc., making it extremely safe and easy to use.

Moreover, since the cooling water is of a water storage type, it is possible to provide a rice cooking device with a very simple configuration that does not require a mechanism for detecting the start of steam generation compared to a flowing water type.
