Benefits of technology

The invention is a lid for an earthen pot used for cooking rice. The lid has steam vents around its edge to prevent solids from spilling out during boiling. The flat, bulky, and heavy lid with the sturdy design prevents overspill and makes it easy to use the earthen pot for rice cooking. The technical effects of this invention are to improve the efficiency of rice cooking and to prevent waste of valuable ingredients.

Problems solved by technology

When the boiling is continued with the 500 W output only, rice can be cooked with a single lid without lowering the output, though there is a problem that steam generated by the intense boiling is changed into water drops to make the inside of the microwave oven wet heavily.

first embodiment

THE FIRST EMBODIMENT

[0032]300 cc of pre-washed rice and 420 cc of water (approximately 1.4 times of the rice) are put into the rice-cooking earthen pot with a lid according to the present invention whose capacity is 1500 cc without taking time to immerse the rice in the water. After heating at 200 W for 5 minutes with a microwave oven, the output is changed to 500 W and then heating is performed for 13 minutes. Or, after heating them into boiling at 500 W, the output is lowered to an output at which boiling can be maintained, heating is performed approximately for 5 minutes and then leaving the pot with the lid approximately for 10 minutes.

second embodiment

THE SECOND EMBODIMENT

[0033]400 cc of pre-washed rice and 560 cc of water (approximately 1.4 times of the rice) are put into the rice-cooking earthen pot with a lid according the present invention whose capacity is 2000 cc without taking time to immerse the rice in the water. After heating at 200 W for 5 minutes with a microwave oven, the output is changed to 500 W and then heating is performed for 15 minutes. Or, after heating them into boiling at 500 W, the output is lowered to an output at which boiling can be maintained, heating is performed approximately for 5 minutes and then leaving the pot with the lid approximately for 10 minutes to cook delicious rice.

third embodiment

THE THIRD EMBODIMENT

[0034]When cooking a gruel, 100 cc of pre-washed rice and 500 cc of water (approximately 5 times of the rice) are put into the rice-cooking earthen pot with a lid according the present invention whose capacity is 2000 cc without taking time to immerse the rice in the water. After heating at 200 W for 5 minutes with a microwave oven, the output is changed to 500 W and then heating is performed for 12 minutes. Or, after heating them into boiling at 500 W, the output is lowered to an output at which boiling can be maintained, heating is performed approximately for 5 minutes and then leaving the pot with the lid approximately for 15 minutes to cook a delicious gruel.

Abstract

The applicant provides a heating vessel with a single lid for a microwave oven wherein boiling is maintained and overspill is unlikely to be ejected. In view of the fact that a wooden lid for an iron pot is flat, bulky and heavy, the applicant employs a thickened intermediate lid for a double-lid earthen pot for rice cooking that is used for heating with gas. By providing steam vents at equal intervals around the circumference of the lid, the soluble solids of cooked rice ejected due to boiling are returned into the earthen pot for rice cooking.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the invention[0002]The present invention relates a heating vessel with a lid, for preventing overspill from being ejected and maintaining boiling even with a single lid, to make it easy for use of an earthen pot for rice cooking with a microwave oven.[0003]2. Description of the related art[0004]The Japanese Patent No. 4143936 discloses that rice can be cooked in a good manner with a simple output control when an earthen pot is used as a vessel for rice cooking with a microwave oven.[0005]For earthen vessels for rice cooking with a microwave oven, there are double-lid rice bowls, earthen pots whose main body and lid are doubled, and triple-lid vessels.[0006]However, the rice-cooking vessels have problems to be solved such as overspill and complicated way of use due to multiple lids.[0007]The present invention is intended to provide an earthen pot with a single lid that prevents overspill from being ejected and maintain boiling for rice coo...
