[Technical background of the invention and its problems]

This type of food cooking machine includes a boiler and a bottomed cylindrical hopper that is removably seated in the opening of the boiler. For example, when making rice cake, washed glutinous rice is first stored in the hopper. Then, steam is generated in a boiler, and this steam is sequentially infiltrated into the glutinous rice through a number of steam passage holes formed in the bottom of the hopper to steam it. After this, the kneading tool placed in the hopper is rotated to knead the glutinous rice.
Finish into mochi.

On the other hand, when making dough for bread or udon, the main raw material, flour, is stored in a hopper. Some of the flour leaks out of the steam passage holes provided, and for this reason, in the past, flour was soaked in water in advance and kneaded to some extent by hand, i.e., pre-kneaded.
After that, the mixture must be put into the hopper and kneading must be started, which is a disadvantage in that it requires inefficient and troublesome work.

However, when making mochi, please refer to Figures 1 and 2.
As shown in the figure, when one fitting recess 36 of the seal cap 32 is fitted into the boss 7, a predetermined amount of water is stored in the boiler 4, and a predetermined amount of washed glutinous rice is placed in the hopper 20. It is housed and the lid body 44 is attached. When the operation switch (not shown) is turned on in this state, only the heater 6 is energized and generates heat, causing the water in the boiler 4 to boil.
The steam is ejected into the hopper 20 through each steam passage hole 27, and infiltrates the glutinous rice one after another, and the glutinous rice is steamed by this steam. When the water in the boiler 4 evaporates in this way, the steaming of the glutinous rice is completed.
In response to this, the heater 6 is de-energized and the motor 5 is energized. In addition, at this time, Hopper 20
The lid body 44 is removed from the container so that the glutinous rice is exposed to cold air from outside.

This starts when the motor 5 is energized, and the kneading tool 3
1 rotates, and the rotation of this kneading tool 31 gradually kneads the glutinous rice, and after a certain period of time, it is finished into a sticky rice cake.

On the other hand, when making dough for bread or udon noodles, the kneading tool 31 is removed from the shaft 8 and the hopper 20 is removed from the guide tube 40 to open the upper end opening of the boiler 4. Then, the seal cap 32 is removed from the upper end of the boss 7, turned upside down, and the other fitting recess 37 is fitted to the upper end of the shaft 8 to be reattached. In other words, it is reinstalled from the upright position to the inverted position. Thereafter, the hopper 20 is again seated at the upper opening of the boiler 4, and the kneading tool 31 is again attached to the shaft 8. At this time,
The seal cap 32 is inverted so that the mounting recess 39 faces upward, so that when the hopper 20 is seated, the protrusion 25 moves into the mounting recess 3.
9, thereby sealing each steam passage hole 27. Under such conditions, Hopper 2
A predetermined amount of wheat flour as the main raw material is stored in a container 0, as well as an appropriate amount of water, various seasonings, or additives such as yeast, and the motor 5 is energized to rotate the kneading tool 31 to mix the flour. By kneading, it is possible to finish the dough for bread and udon.

Here, each steam passage hole 27 of the hopper 20 is sealed by a seal cap 32, so even if flour is stored in the hopper 20 in powder form, it leaks through the steam passage hole 27. There is no such thing as doing that. In addition, flour may sometimes enter the small gap between the shaft 8 and the insertion hole 26, but even in such cases, the gap is separated from the inside of the boiler 4 by the partition wall 34 of the seal cap 32. This prevents its leakage. Of course, it is also possible to attach separate packing or the like to the periphery of the insertion hole 26 to prevent leakage of flour. Also, seal cap 32
When the hopper 20 is attached to the upper end of the boss 7 in either the upright position or the inverted position, the seal cap 32 supports the center of the bottom of the hopper 20, so the hopper 20 can sit comfortably and its stability is maintained at all times. It has the advantage of being able to be used in a variety of ways.

The food cooking machine configured in this way can be used not only to make dough for mochi, bread, or udon, but also to make sekihan in the same manner as steaming glutinous rice.
Alternatively, steam ejected from the steam passage hole can be used to boil eggs in the hopper or to perform steam cooking such as chawanmushi. Further, in the above embodiment, a protrusion is formed on the bottom of the hopper,
A steam passage hole is bored in the peripheral wall surface of the protrusion, and a mounting recess is formed in the seal cap to fit into the protrusion, and the mounting recess is fitted into the protrusion to seal the vapor passage hole. However, the configuration is not limited to this, and there is no problem in making a steam passage hole in the horizontal bottom of the hopper and simply sealing the steam passage hole by placing a seal cap on the bottom. .

[Effect of idea]

As explained above, according to this invention, a seal cap is removably attached between the upper end of the boss through which the shaft penetrates and the bottom surface of the hopper, and the seal cap is placed in a normal position with respect to the upper end of the boss. The seal cap is configured so that it can be installed in an inverted state, and when making bread or udon dough, the seal cap is inverted to seal the steam passage hole in the hopper, so flour can be stored in the hopper in powder form. Therefore, there is no need to pre-knead flour, and you can easily and efficiently enjoy making bread and udon dough.Also, the center part of the bottom of the hopper is sealed during any cooking process. Since it can be supported through the cap, it has the effect of ensuring its stability.
