Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a pot used for boiling noodles and pasta.

(Prior Art) Conventionally, it has been known that when boiling noodles, it is a good condition to boil them in a short time using a large amount of boiling water. For this reason, a pot consisting of an inner pot with many holes and an outer pot was used.

(Problem that the invention aims to solve) When boiling noodles in a large amount of water using the conventional inner pot and outer pot as described above, a large amount of foam is generated and bubbles over the top of the outer pot or inner pot. Therefore, it is necessary to pour water each time to lower the temperature and prevent boiling over, and there is a problem in that the temperature decreases each time, resulting in a decrease in thermal efficiency.

In view of the above-mentioned problems, the purpose of this invention is to provide a pot that eliminates the trouble of pouring water when bubbles occur, suppresses the rise of bubbles, extinguishes the bubbles, and prevents boiling over without reducing thermal efficiency. This is what we provide.

(Structure of the invention) (Means for solving the problems) The pot of the present invention includes an outer pot, an inner peripheral surface and a bottom surface of the outer pot. It consists of an inner pot that stands up above the outer pot, and a bowl-shaped transparent lid that is fitted into the upper opening of the inner pot and can be turned over and left standing. The surface is formed into an annular step with a wide outward bulge,
A large-diameter upper end circumferential wall portion that rises upwardly is formed continuously from this annular step portion, and the upper circumferential surface of the inner pot is formed to bulge outward shallowly at the annular step portion of the outer pot. An annular protruding portion formed by the above-mentioned outer pot is engaged with the annular protruding portion, an annular space is formed between an upper circumferential wall portion formed by extending the upper end of the annular protruding portion upwardly, and a large-diameter upper end circumferential wall portion of the outer pot; A circumferential surface continuous to the lower end of the annular protrusion is brought close to the inner circumferential surface of the outer pot to form an annular bulge, and a group of first-stage water holes is provided on the circumferential surface near the highest water level of the inner pot. This first stage is formed below the first stage water passage group.
A second stage water passage hole group having a slightly smaller diameter than the second stage water passage hole group is formed, and a bottom water passage hole group having a slightly smaller diameter than the second stage water passage hole group is formed on the bottom surface of the inner pot. This is what happens.

(Function) When boiling noodles, the pot of the present invention has a continuously formed annular bulge at the bottom of the annular protrusion of the inner pot that is engaged with the annular stepped portion of the outer pot. Since the flow gap is narrowed by being close to the circumferential surface, bubbles blown up from the flow gap are crushed between the annular bulges of the outer pot and the inner pot, and are further crushed between the annular stepped portion of the outer pot and the inner pot. The bubbles are crushed and extinguished between the annular protrusions of the pot and do not blow up upwards, and in the unlikely event that bubbles are blown up, they are stored in the wide space between the upper circumferential wall of the inner pot and the upper circumferential wall of the outer pot. It is accepted by the public and does not spill over to the outside world. In addition, the hot water containing bubbles flowing out from the upper part of the first stage water hole group and the second stage water hole group of the inner pot flows down through the hot water distribution gap and reaches the second stage water hole group or the bottom surface. Water flows into the inner pot from the water holes and circulates.

In addition, when exposing the noodles to water, the bowl-shaped lid can be used as a bath by inverting the lid.

(Example) An example of the present invention will be described with reference to the accompanying drawings.

Reference numeral 1 denotes an outer pot, in which an annular stepped portion 3 with a circumferential surface bulging widely outward is formed near the upper end opening 2, and the upper end of this annular stepped portion 3 rises upward as it is and has a large diameter. An upper end peripheral wall portion 4 is formed.

5 is an inner pot, and an annular protrusion 6 having a narrow arcuate cross section and shallowly bulging outward is formed in the middle of the circumferential surface;
This annular protruding portion 6 engages with the annular step portion 3 of the outer pot 1 to hold the inner pot 5 in the outer pot 1, and between the outer circumferential surface of the inner pot 5 and the inner circumferential surface of the outer pot 1, A flow gap 7, 8 is formed between the inner pot 5 and the bottom surface 16 of the outer pot 1. Further, the circumferential surface of the inner pot 5 that is continuous with the lower end of the annular protrusion 6 is bulged outward, and the distance between the outer pot 1 and the outer pot 1 is increased.
between the upper circumferential wall section 10 formed by forming an annular bulging section 9 that minimizes the diameter of the annular projection section 7 and extending the upper end of the annular protruding section 6 upward, and the large-diameter upper end circumferential wall section 4 of the outer pot 1; A wide and high space portion 10a having a height of 30 mm to 35 mm from the annular step portion 3 is formed in the upper peripheral wall portion 1.
The upper end of the outer pot 1 is expanded outwardly in an arc shape above the large-diameter upper end circumferential wall portion 4 to form an enlarged mouth wall portion 12 having an opening 11 on the upper surface. A bent edge 13 is formed by bending the upper end of the wall portion 12 outward, further downward, and then inward.

Furthermore, the highest water level 1 of the inner pot 5 is suitably 52/100 of the height H from the bottom of the outer pot 1 to the top opening 11 of the inner pot 5, and the highest water level of the peripheral wall of the inner pot 5 is 14 groups of 1st stage water holes with a diameter of 4 mm are formed in 3 stages at a pitch of 5 mm in FIG. There are 20 groups of 15 second-stage water holes with a diameter of 2.5 mm at the same pitch as the 14 groups of first-stage water holes. Furthermore, the bottom surface 16 of the inner pot 5 is formed with several downwardly bulging protrusions 17, and a group of 18 water holes each having a diameter of 2 mm.
It is formed with a pitch of ₁ = 5 mm and ₂ = 8 mm.

Reference numeral 19 denotes a bowl-shaped lid made of transparent heat-resistant glass, which includes a flange portion 20 that fits into the opening 11 of the inner pot 5 and engages on the bent edge 13 of the inner pot 5;
A fitting edge 2 that is internally fitted into the enlarged mouth wall 12
1 is formed. The top surface of the lid 19 is flat and configured to prevent it from wobbling when it is turned over and used as a bowl.

Next, the operation of the above embodiment will be explained.

The inner pot 5 is housed inside the outer pot 1, and the annular stepped portion 3 of the outer pot 1
The annular protrusion 6 of the inner pot 5 is engaged with the inner pot 5 to suspend the inner pot 5 within the outer pot 1. At this time, the annular bulge 9 of the inner pot 5 approaches the inner circumferential wall of the outer pot 1 and does not move back and forth or left or right within the outer pot 1 of the inner pot 5, and the flow distance 7 is kept constant. Water is poured into the inner pot 5 to the highest water level L position, a lid body 19 is fitted onto the inner pot 5, and the water is heated to boil. Next, when the lid body 19 is removed and the noodles are boiled, a large amount of bubbles is generated and rises in the inner pot 5, but some of the generated bubbles are absorbed by the bubbles formed near the highest water level of the inner pot 5. Between the inner pot 5 and the outer pot 1 from the top of the first stage water holes 14 and the second stage water holes 15 group
7, it flows out with hot water. The hot water flows down the gap 7 and flows into the inner pot 5 again through the second stage water passage hole 15 or the bottom water passage hole 18 of the inner pot 5 and circulates.
As a result, the bubbles built up in the inner pot 5 do not boil over from the opening 11 at the top end. In addition, the bubbles rising from the gap 7 are between the inner peripheral wall of the outer pot 1 and the inner circumferential wall of the inner pot 5.
It is crushed and defoamed in the narrow space between the outer walls of the annular bulge 9, and is further crushed by the annular step 3 of the outer pot 18 above and the annular protrusion 6 of the inner pot 5. The foam is defoamed. Also, in the event that it blows up onto the annular stepped portion 3 of the outer pot 1, the width having the height formed by the large-diameter upper end circumferential wall portion 4 rising upward and the upper circumferential wall portion 10 of the inner pot 5 is The large space 10a prevents boiling over from the upper end opening 2 of the outer pot 1.

Next, when the noodles are boiled, pour cold water into the lid 19, then lift the inner pot 5 containing the noodles from the outer pot 1, expose it as it is, and immerse it in the cold water in the lid 19, which serves as a gutter. Pour in cold water and soak the noodles in the cold water.

Next, the inner pot 5 and the noodles are pulled out of the water in the lid 19, and the exposed noodles are placed in the lid 19 serving as a serving container.

Also, if the noodles are like spaghetti, the lid body 19
It can also be mixed with other materials inside.

Since the lid body 19 is made of heat-resistant glass with a temperature difference of 100° C. to 150° C., it is also possible to rapidly cool the noodles when exposing them to water.

(Effect of the invention) According to the invention, the annular protrusion of the inner pot is engaged with the annular stepped portion in the outer pot, and the inner pot is supported within the outer pot via the flow gap. Since the annular bulge formed at the bottom of the annular protrusion is brought close to the inner circumferential surface of the outer pot, the bubbles flowing out from the water hole of the inner pot into the flow gap are crushed between the annular bulge and the outer pot. The bubbles are then defoamed between the annular protrusion and the annular step, and the foam blown out onto the annular step is received in the wide space formed between the inner pot and the outer pot, and is absorbed into the lower part of the outer pot. Less likely to boil over. Therefore, the noodles can be boiled efficiently and easily because there is no need to take the trouble of pouring cold water in the middle of boiling the noodles, and there is no need to lower the temperature.

The bowl-shaped lid can also be used as a gutter for exposing boiled noodles to cold water or as a table container.

Furthermore, the outer pot can also be used as a stew pot or a deep pot.

It can also be used as a steamer by combining the outer pot and inner pot with a lid.
