An outer ring (41) is provided, and the outermost long ring (41a) also serves to prevent water droplets and steam from leaking to the outside. At this time, the lid (4) is formed with a curved surface facing upward, and the gap (33a) of the inner lid (3) and the tank body (2) are formed in the gap between the inner peripheral wall and the long ring (41a). The top of is inserted. A handle (42) is integrally provided on the upper surface of the lid (4). In addition, as a material of the said inner lid (3) and a cover body (4), although it is good to use heat resistant glass or a heat resistant synthetic resin, it is not limited to this material. Further, a projection shown in FIG. 4 may be provided on the inner wall of the lid body (4), and the projection may be engaged with the upper outer periphery of the tank body (2). (5) is a rising pipe such as a stainless steel pipe or a heat-resistant synthetic resin pipe provided between the center of the bottom of the tank body (2) and the center of the bottom of the inner lid (3). The rod body (51) is approximately the same length as the tank body (2), and is fixed to the end of the tube section (51) and can be inserted into the insertion hole (21a) of the protruding cylinder (21). There is an insertion part (52). The insertion portion (52) is formed in a short cylinder shape substantially the same size as the protruding cylinder (21), and has an outer peripheral surface with a lower end thereof squeezed. A plurality of inflow holes (52a) for supplying water to the inside of (21) are provided. The shape of the insertion portion (52) may be formed in other shapes as long as it can be attached to the insertion hole (21a).

  Next, the operation of the present invention will be described with reference to FIG. When using the product of the present invention for the first time, a desired amount of water is put in the tank body (2) in advance and placed on the heating section (11) of the heater (1). At this time, the protruding cylinder (21) of the tank body (2) is also inserted into the recess (12) of the heater (1). Then, the riser pipe (5) is put into the tank body (2), and the insertion part (52) is inserted into the insertion hole (21a) of the protruding cylinder (21), and the upper end of the pipe part (51) is attached to the inner lid (3 ) Is inserted from below the fitting cylinder (31), and the inner lid (3) is inserted into the upper part of the tank body (2), thereby completing the mounting of the riser pipe (5) and the inner lid (3). . Then, coffee powder is directly put on the filter part (32) of the inner lid (3). In addition, when putting the coffee powder into the inner lid (3), if the filter part (32) is not formed in a mesh shape, a not-shown inner hole is formed on the filter part (32). After putting the cut out filter paper, put coffee powder. When the lid (4) is placed over the inner lid (3), the upper part of the tank body (2) is also covered, and the preparation is completed. At this time, the product of the present invention is substantially sealed. Next, a case where coffee liquid is extracted will be described. First, the power switch of the heater (1) is turned on, and the water in the tank body (2) is heated from the heating part (11) and the recessed part (12). At this time, mainly the water is rapidly heated by the recess (12).

  When water heated and boiled, it passed from the protruding cylinder (21) of the riser pipe (5) through the pipe part (51) as shown by the white arrow in the figure, and was erected at the center of the inner lid (3). Hot water and steam are uniformly dispersed in a space that is ejected from the spout (31a) at the upper end of the fitting cylinder (31) and is sealed by the inner lid (3) and the lid (4). The hot water and steam spouted at this time hit a plurality of concentric rings (41) at regular intervals provided on the lid (4) and are poured from above the coffee powder as indicated by dotted arrows in the figure. . Further, when hot water is ejected from the protruding cylinder (21) through the riser pipe (5), the amount of hot water in the protruding cylinder (21) is reduced, so that the low temperature hot water at the bottom of the tank body (2) flows into the inflow hole (52a ) To the inside of the protruding cylinder (21) as indicated by the arrows in the figure. In this way, the water in the tank body (2) is heated and boiled, passes through the ascending pipe (5), is ejected from the spout (31a) of the fitting cylinder (31), and the coffee liquid is extracted. The extract continues to drip from the filter part (32) into the tank body (2). Since the dropped coffee liquid is considerably higher than the temperature on the dropping surface and has a low specific gravity, a layer of coffee liquid is formed on the water surface and remains floating with little mixing. Then, when the border of the coffee liquid falls below the discharge port (22) or is completely filled with the coffee liquid, open the discharge port (22) with a cock or the like, and put the coffee liquid in a coffee cup (not shown) and drink good. And when the coffee liquid of a tank main body (2) becomes empty, it is good to turn off the power switch of a heater (1). If the coffee liquid remains in the tank body (2), turn off the heater around the recess (12) with the changeover switch and put only the heater in the heating section (11) to keep it warm. good.

  A case where the coffee liquid in the tank main body (2) becomes empty and the product of the present invention is cleared will be described. First, lift the outer periphery of the tank body (2) by hand, remove it from the heater (1), and take it to a washable place such as a kitchen or sink. Next, the lid (4) is taken out, the inner lid (3) is taken out, and the internal coffee powder is disposed of. Then, each part is disassembled by pulling out the rising pipe (5). Next, if each part is washed with water and the water is turned off, the washing of the product of the present invention is completed. In addition, for each part that has run out of water, the rising pipe (5) is erected inside the tank body (2), and the inner lid (3) and the lid body (4) are put on the upper part of the tank body (2). And if it is placed on the heater (1), the tidying up is complete. As described above, the product of the present invention is easy to disassemble and easy to clean, and the entire apparatus is shaped like a mixer without a handle, which is simple and compact compared to a conventional coffee maker. It is.

It is a perspective view which shows the disassembled component of embodiment of this invention. It is explanatory drawing which shows the principal part cross section of this embodiment. It is explanatory drawing which shows the cross section of the inner lid of this embodiment. It is explanatory drawing which shows the cross section of the cover body of this embodiment.
