PURPOSE:To easily extract tasty drink, such as coffee, etc., holding satisfactory quality in a microwave oven by executing the extraction while partially blocking the interference of high frequency power with an upper part vessel, etc. CONSTITUTION:Water in a lower part vessel 12, for which an aperture is equipped in an upper part and a cap cover 14 to have a central aperture 142 is equipped in an upper part aperture 122, is heated with the high frequency. Through a conduit 162 which is inserted through the central aperture 142 of the cap cover 14 and arranged with closing a lower edge to the bottom part of the lower part vessel 12, the heated water is conducted into an upper part vessel 16 like a siphon. The drink is extracted from a substance S, to be extracted which is contained through a filter 18 into the upper part vessel 16, by the above mentioned heated water. By giving the partial, at least, high frequency reflecting characteristic of the upper part vessel 16 or covering the upper part 16 with a high frequency reflecting member, the extraction is executed while the interference of the high frequency into the upper part vessel 16 is partially blocked at least. As a result, the tasty drink such as the coffee, etc., can be easily extracted in the electronic range with holding the satisfactory quality. |
