Description

[Detailed description of the invention] Industrial applications The present invention relates to a rice cooker.

2. Description of the Related Art Conventional rice cookers emit steam generated during cooking into the room through a steam vent or the like.

Problems to be Solved by the Invention The temperature increases the cloudiness in the room, causing discomfort to the user, and causes condensation of steam on walls and furniture near the rice cooker, causing damage. .

Means for Solving the Problems The present invention has been made in relation to the above-mentioned problems.5 A cooler is provided between the outer frame of the main body and the inner container, and a steam introduction pipe is provided in the lid body to guide the steam generated from the inner pot to the cooler. It is something that

Function: With this configuration, it is possible to reduce the amount of steam generated during rice cooking that is discharged to the outside of the rice cooker.

Example An embodiment of the present invention will be described below with reference to the drawings.

Examples thereof are shown in FIGS. 1, 2, and 6.

In the figure, 1 is the main body outer frame attached to the bottom 2, the filter is the main body ring provided at the upper end of the main body outer frame 1, 4 is the inner container equipped with a heating plate 5 at the bottom, and 6 is the inner container 4 and heated. Board 5
The inner pot 9 provided on the top is a lid and is rotatably provided at the main body hinge 8 of the main body ring 6, and an inner lid 7 that covers the inner pot 6 is provided on the lower surface of the interior.

10 is a cooler provided between the main body outer frame 1 and the inner container 4 and on the lower surface of the main body ring. Replacement board 11
An appropriate number of hollow ventilation holes 12 are installed alternately and vertically.
12. Furthermore, the groove 15 is provided with a partition wall 22 which is a concubine cutter, and a discharge port 21 is provided at the bottom near the partition wall 22. 14 is an intake hole formed between the bottom 2 and the cooler 10.

13.13 is an exhaust hole that corresponds to and communicates with the ventilation hole 12.12, 16 is a steam flow hole located in the upper part of the cooler 10 near the partition wall 22 without the drain port 21, and 17 is a steam inlet hole 16. The gasket 18 provided at the top is a steam outlet provided on the main body ring B and is located above the discharge port 21 of the cooler 10. A tank 19 is located below the discharge port 21 and is detachably attached to the bottom 2. Reference numeral 20 denotes a steam introduction pipe provided in the lid body 9; one end is connected to the space above the inner pot 6 covered with the inner lid 7, and the other end is connected to the main body through a pankin 17.
It is provided so as to be in communication with the steam inflow hole 16 of.

Next, the effect of the above configuration will be explained.

5 starts to be energized. When steam is generated in the inner pot 6 and reaches a certain pressure or higher, it flows into the steam introduction pipe 20 opened from the inner lid 7.
Steam is guided by the pressure inside the inner pot 6. Steam introduction pipe 2
Since the other opening of 0 is in close contact with the main body ring 2 through the packing 17, steam is guided into the cooler 10 through the steam inflow hole 16 without leaking. The steam that has entered the cooler 10 passes through the groove 15 and advances toward the steam outlet 18. On the way, the steam comes into contact with the heat exchange plate 11, and is cooled and condenses.

Therefore, the amount of steam that reaches the steam outlet 18 is extremely small, and the steam that has reached the steam outlet 18 is also lower in temperature and pressure than in the inner pot 6. On the other hand, the steam condensed on the heat exchange plate 11 flows along the bottom of the cooler 10, is drained from the drain port 21, and is collected in the tank 19. In addition, the heat exchange plate 11 is heated by the steam, but heat is transferred from the surface of the groove 15 side of the exchange plate 11 to the surface of the vent hole 12 side due to thermal conduction.
Heats the air inside 2. The heated air rises due to natural convection and is exhausted from the exhaust hole 13 provided in the main body ring 3, and then flows through the lid body 9 and the main body ring 3.
mixes with the atmosphere from the gap between the

On the other hand, new air is introduced into the 8 ventilation holes 12 from the intake holes 14 provided at the bottom 2 and the cooler 10 mounting part, and by continuing this operation, the heat exchange plate 11 is cooled, and the steam is continuously cooled. I can do it.

Through the above operations, the steam collected in the cooling 2 is transferred to the tank 19.
By removing it, you can throw it away as water.

Effects of the Invention As described above, in the present invention, a cooler (heat exchanger) is provided between the outer frame of the main body and the inner container, and steam generated during rice cooking is introduced into the cooler through a steam introduction pipe provided on the lid. By cooling and condensing, the amount of steam emitted is reduced, eliminating discomfort for the user and no longer causing damage to walls or furniture due to condensation.

Further, in the illustrated embodiment of the present invention, a heat exchanger is provided along the entire circumference between the outer frame of the main body and the inner container, but it is also possible to remove a part of the heat exchanger due to the arrangement of the caliper 1 and the like.

It is not limited to providing it all around.
