Description

Detailed Description of the Invention The present invention relates to a rice cooking device having a steam condensing device, which uses a cooling medium to recover the thermal energy of steam released in large quantities during rice cooking, and converts the steam into low-temperature, low-humidity air. The purpose is to provide the amount of rice cooking equipment to be exhausted.

Rice cooking devices exhaust a large amount of steam while cooking rice, but conventionally, no rice cooking device has been provided that has a device for condensing steam. Therefore, conventionally, high temperature.

The highly humid steam was directly exhausted into the room. but,
Since a large amount of moisture was released into the room, moisture was trapped inside the room and condensed on the walls, making it very inconvenient to use.

Furthermore, the emitted steam is at a high temperature, and there is a risk of burns if the user accidentally touches it. Therefore, exhaust ports were provided on both sides of the main body to ensure safety for the user. Therefore, when installing a rice cooker, there was a problem in that a space had to be provided on the exhaust port side. Another drawback was that the rice cooker could not be incorporated into the system kitchen.

The present invention solves the above-mentioned conventional drawbacks, recovers the thermal energy of steam released during rice cooking using a cooling medium, and exhausts the steam 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 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 surface of the main body 1. 6 is a steam condensing device, one end 8 is an exhaust port opened on the front surface of the main body, and the other end 7 is a drain port for condensed water.

The third page 8 is a steam inlet provided on the bottom of the fuselage. 9 is rice cooker 3
The steam port oll provided in the lid 10 is a steam guide with both ends open, one end 12 being disposed at a position facing the steam port 9, and the other end being a steam port of the steam condensing device 5. It is closely attached to 8. A water supply tank 13 is arranged above the steam condensing device 5. Water is appropriately supplied to this from a water supply pipe 16 provided with a water supply valve 14. Of course, the water supply pipe 16 is connected to a water supply source (not shown) such as water supply, and 016 is a cooling pipe, which is wound in a spiral shape to increase the heat exchange area inside the steam condensing device 5. 17 is connected to the water tank 6 via the solenoid valve 18.
At the bottom, the other end 19 is connected to a drain pipe 20. Of course, the drain pipe 20 is connected to a sewer (not shown). 21
is a drain pipe that communicates the drain pipe 20 with the lower part of the body 5 for draining condensed water. 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 below. First, add rice and water to the rice cooker, then
Remove rice cooker 3 and place it in 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
operates, and water in the water supply tank 13 flows through the cooling pipe 16 and is drained to the sewer or the like through the drain pipe 2o. The steam released from the steam hole 9 passes through the steam guide 11 and is led into the steam condensing device 6, where it comes into contact with the cooling pipe 16 and is stripped of thermal energy by the water flowing inside the cooling pipe 16, so that the surface of the cooling pipe 16 is Condensation occurs in the air, resulting in low-temperature, low-humidity air that is exhausted from the exhaust port 6. Further, the condensed water is drained from the drain lower through the drain pipe 21 and the drain pipe 2o to the sewer or the like. When rice cooking is finished and steam is no longer released, the solenoid valve 18 stops operating.

The operations described above are performed by an appropriate control circuit (not shown) such as a timer.

Although water was used as the cooling medium in this example,
Any other medium may be used for this, such as air.

- As described above, according to the rice cooking device of the present invention, steam is condensed by the steam/air condensing device and exhausted as low-temperature, low-humidity air, thereby eliminating the possibility of moisture being trapped indoors.

Furthermore, even if the exhaust port is provided in the front, there is no danger of burns or the like, so not only does the installation not require a large space, but it can also be incorporated into a sink, cooking table, etc.
