Description

The structure of the continuous cooking pot from the fire

technical field

The invention relates to a structure of a continuous cooking pot from the fire, which can be used as an inner pot of a stewing pot or a cooking pot for household use, and has good effects of increasing temperature for continuous cooking and maintaining heat for a long time.

Background technique

There are many pots on the market that enable the pot body to keep warm or heat after the heat source stops burning. For example, the stewing pot 10 shown in FIG. 1 is an example, which includes an outer pot 11 and an inner pot that is placed in the outer pot 12. After assembly, as shown in Figure 2, the outer pot 11 has a hollow thermal insulation layer 112, so it has the function of heat insulation and heat preservation, and the inner pot 12 is against the upper edge of the outer pot 11 with the top edge, the bottom and the outer pot 11. The ring wall keeps an appropriate distance from the outer pot 11, and the inner pot 12 is covered with a pot cover 13, while the outer pot 11 is sealed and pressed with a cover 111; After being heated to boiling, it can be moved into the outer pot 11, and then the heat energy is retained in the pot by the heat insulation of the outer pot 11, so that the food in the inner pot 12 can be continuously stewed, and has a long-term heat preservation effect.

However, in order to make the heat storage and heat preservation function of the inner pot 12 better, the bottom of the inner pot 12 is thickened into a thickened layer 121 in the industry. The heat and heat preservation effect will be better, but the heat energy will still be quickly absorbed by the food in the inner pot, so the temperature will also be cooled quickly, so although the effect is improved, it is very limited.

In order to solve the aforementioned problems, the applicant has developed a special inner pot for stewing, and has applied for multi-national patents. The application number of Taiwan, China is No. 90203767 "Structure of a stewing pot", and its structure is shown in Figure 3 of this case. As disclosed, several fixing pieces 18 are arranged on the bottom ring of an inner pot 12, and then a piece of heat collecting ring 19 is fixed under the fixing piece 18. The heat collecting ring 19 and the bottom surface of the inner pot 12 keep a distance S; when the inner pot is placed When burning on the combustion source 20 (gas stove), the fire will pass through the perforation 191 of the heat collecting ring 19 to heat the bottom of the pot. When the food in the pot began to boil (about 95° C.), the temperature of the heat collecting ring 19 has When it reaches the red state of 500-600°C, since the distance S between the heat collecting ring 19 and the bottom of the pot is maintained, the heat energy will not be directly transmitted to the inner pot 12, so after the inner pot 12 is moved into the outer pot 11, the heat collecting ring 19 is sufficient. The "reheating" function of the inner pot makes the food cook faster, which can shorten the cooking time of the food and greatly reduce the use of fuel. Compared with the traditional stewing inner pot, it is indeed effective increase.

Although the above-mentioned inner pot with a heat collecting ring at the bottom of the pot can achieve an excellent heating function, there are still the following problems to be solved, such as:

1. The heat-gathering ring is fixed under the inner pot with a single piece. When it is placed in the outer pot for simmering, its heating effect will be stronger than that of the traditional form, so the simmering time must be shortened; but due to the user's negligence As a result, the cooking time is too long, causing the food in the pot to be overcooked and overcooked.

2. Since the heat collecting ring has a flat bottom, housewives often accidentally place the inner pot on the table. However, the temperature of the heat collecting ring after heating is 500-600°C, so it is easy to burn the table or table mat.

3. The heat gathering ring is fixed under the inner pot, not only cannot be removed, but also cannot be increased or decreased, so the temperature cannot be controlled.

4. The combustion rate of general gas combustion is only about 70-80%. Since it does not reach full combustion (100%), the air is filled with gas smell, but when the gas passes through the red heat-gathering ring, it can make the gas reach The effect of almost full combustion, but it cannot achieve the desired effect when the through holes are too large or the number of holes is too small.

Contents of the invention

The object of the present invention is to provide a structure of a continuous cooking pot with off-fire function for "rewarming" and continuing cooking of the food in the pot through the heat energy released by the bottom heat collecting ring after being heated.

For realizing the above object, technical means of the present invention mainly contains two items, are respectively:

One, a kind of structure that continues cooking pot from fire, is characterized in that:

The heat-gathering ring is fixed in the center of the bottom of the cooking pot with a screw structure, and an appropriate distance is reserved between the heat-gathering ring and the bottom of the pot so that the heating heat energy cannot be directly conducted to the bottom surface of the cooking pot.

Its function is to fix at least one heat-gathering ring in the center of the bottom of the cooking pot in a screwed manner, and keep an appropriate distance between the heat-gathering ring and the bottom of the pot. When the bottom of the pot is heated, the heat-gathering ring converges to a high temperature; The heat ring keeps a considerable distance from the bottom of the pot, so the heat energy cannot be directly transmitted to the cooking pot, so the temperature of the heat-collecting ring cannot rise due to the heat dissipation effect of the liquid in the pot. Accordingly, the heat-collecting effect of the heat-collecting ring can The cooking pot is heated and continued to cook and keep warm.

According to the structure of the above-mentioned continuous cooking pot from the fire, the screw setting method is that the central screw rod under the inner pot is screwed into the screw hole provided at the center of the heat gathering ring to fix it.

According to the structure of the above-mentioned continuous cooking pot from the fire, its screwing method is a central nut welded under the inner pot, which can be screwed in by the screw rod in the center of the top surface of the heat-gathering ring.

According to the structure of the above-mentioned continuous cooking pot from the fire, when the set heat-gathering rings are stacked and combined, the center of the bottom heat-gathering ring is provided with a screw hole to be screwed with the screw under the inner pot, while the remaining heat-gathering rings All have central perforations for bolts to pass through.

According to the structure of the above-mentioned continuous cooking pot from the fire, when the set heat-gathering rings are combined with several overlaps, each heat-gathering ring center has a hole for the bolt to pass through, and the bottom end of the screw rod is screwed with a nut.

According to the structure of the continuous cooking pot from the above-mentioned fire, when the set heat-gathering rings are combined with several overlaps, the screw hole at the center of the bottom surface of the heat-gathering ring is provided for the screw at the center of the top surface of the next heat-gathering ring to screw in.

According to the structure of the above-mentioned continuous cooking pot from the fire, wherein, the heat collecting ring is provided with a plurality of through holes so that the fire can burn to the bottom surface of the inner pot after passing through.

According to the structure of the above-mentioned continuous cooking pot from the fire, the bottom end of the central screw rod is an arc end.

According to the structure of the continuous cooking pot from the fire, wherein, the top end of the central screw rod is provided with a top block with a wide diameter and an appropriate thickness.

2. Another example is the structure of a continuous cooking pot from the fire, which is characterized in that: the bottom ring of the pot is provided with a ring of fixed rings, the inner wall of the fixed ring has internal threads, and the heat gathering ring with external threads on the outer edge is mutually Screwed together, there is an appropriate distance between the heat-gathering ring and the bottom of the pot so that the heating heat can not be directly conducted to the bottom surface of the cooking pot.

Its function is that when the bottom of the cooking pot is heated, the heat collecting ring converges to a high temperature; since the heat collecting ring and the bottom of the pot keep a considerable distance, the heat energy cannot be directly transmitted to the cooking pot, so it is not affected by the heat dissipation effect of the liquid in the pot. As a result, the temperature of the heat-gathering ring cannot be raised, and accordingly, the heat-gathering effect of the heat-gathering ring can be used to increase the temperature of the cooking pot and continue to cook and keep warm.

According to the structure of the above-mentioned continuous cooking pot from the fire, when the heat-gathering rings are implemented with several overlaps, the outer thread of the heat-gathering ring at the bottom needs to be screwed with the inner thread of the safety ring, while the other heat-gathering rings do not. External thread needs to be set.

According to the structure of the above-mentioned continuous cooking pot from the fire, a protrusion can be arranged under the bottom surface of the bottom of the pot to facilitate the stop of the heat-gathering ring to keep an appropriate distance from the bottom of the pot.

Can obtain following advantage by implementing the present invention:

1. It can decide whether to increase or decrease the heat-gathering ring depending on the type of food or the length of time, so the temperature can be controlled. For example, when it is necessary to heat higher or increase the heating time, the heat-gathering ring can be added; otherwise, the heat-gathering ring can be reduced. The usage amount of the ring, so the present invention has the function of increasing or decreasing the heat-gathering ring.

2. The perforation of the heat-gathering ring can allow the fire source to pass through to heat the bottom of the pot. Since the combustion rate of general gas combustion is only about 70%, the incompletely burned gas can reach Re-burning effect, so the heat-gathering ring can make the gas burn almost completely, so as to reduce the carbon deposit at the bottom of the pot and reduce the gas smell in the air, and avoid lung lesions caused by excessive inhalation of the human body.

3. The bottom end of the central screw under the inner pot is an arc end or a screw cap. This arc end or nut protrudes under the heat collecting ring, so the inner pot cannot be placed horizontally on the table, so Be alert to the user not to place the heated inner pot on the table, so as to avoid the high-temperature heat-gathering ring from causing burns to the table or table mat.

4. Based on the use of the heat-gathering ring, it can shorten the cooking time of food and save more energy at the same time.

Detailed ways

According to the embodiment shown in the drawings, the detailed description is as follows:

first embodiment

As shown in Fig. 4 and Fig. 5, they are respectively the three-dimensional exploded view and the combined view of the stewing pot of the present invention. The figure reveals that the structure of the outer pot 11 of the stewing pot 10 is the same as that of the traditional outer pot, so no more details are given here. As for the improvement of the structure of the cooking pot 12, the heat collecting ring 15 is screwed in the center of the bottom of the pot 122, and an appropriate distance S2 must be reserved between the heat collecting ring 15 and the bottom of the pot (see Figure 6), so that after the cooking pot 12 is heated, the heat collecting The temperature of the heat ring 15 will be higher than the temperature of the cooking pot 12. This is because the heat collecting ring 15 keeps a considerable distance from the bottom of the pot 122, so the heat energy cannot be directly transmitted to the cooking pot 12, so it is not subject to the heat dissipation effect of the liquid in the pot to cause heat accumulation. The temperature of the heat ring 15 cannot be raised; when the cooking pot 12 is moved into the outer pot 11, the heat collecting effect of the heat collecting ring 15 can heat the cooking pot 12 and keep it warm for a long time.

The above-mentioned screw setting method is that the bottom 122 of the cooking pot 12 is welded to a central screw 14 so as to be screwed with the central screw hole 151 of the heat collecting ring 15. The maximum distance between the heat collecting ring 15 and the bottom of the pot 122 is S2, but when After the heat-gathering ring 15 continues to screw upwards, it will be blocked by the top block 141 at the upper end of the screw rod 14. The diameter of this top block 141 is larger than that of the screw rod 14, and its thickness S1 is the minimum distance between the heat-gathering ring 15 and the bottom of the pot 122.

When the cooking pot 12 is placed on the combustion source 20 (such as a gas stove) and heated for a period of time, as long as the food in the inner pot reaches a boiling temperature of about 95-100°C, the temperature of the heat-gathering ring 15 has reached 500-600°C and turns red. At this time, the cooking pot 12 is moved into the outer pot 11 (as shown in Figure 7), and the top edge 120 of the inner pot will be attached to the top frame 113, so that the heat collecting ring 15 is not in contact with the bottom surface of the outer pot 11; The temperature in 11 is no longer the traditional 95-100°C. Instead, the "reheating" function is achieved under the heating effect of the heat-gathering ring 15, which makes the temperature rise to 100-110°C or higher. Therefore, food The ripening is faster, the holding time is longer, the cooking effect is better, and it also achieves the effect of saving energy.

In the foregoing, the bottom end of the central screw 14 is an arc end 142, which cannot be screwed into the heat collecting ring 15, so it protrudes below the heat collecting ring 15, which prevents the cooking pot 12 from being placed horizontally. Therefore, the user can be reminded not to place the heated inner pot on the table, so as to avoid the high-temperature heat-gathering ring 15 from causing damage to the table or the table mat.

As shown in Figure 8, corresponding to the aforementioned structure, another feature of the present invention is that a safety ring 123 is provided on the periphery under the bottom of the pot 122, which surrounds a hidden space, and this hidden space enables the heat collecting ring 15 to be located in it. , and the height of the safety ring 123 is greater than the thickness of the set heat-gathering ring 15, so that when the cooking pot 12 is moved to the table or the heat preservation pad, the table top or table mat can be avoided from being burned. Several perforations 124 are arranged on it to facilitate air convection.

second embodiment

As shown in Fig. 9 and Fig. 10, it is a three-dimensional exploded view and a full-section combined view of the inner pot of the second embodiment. The difference between this example and the aforementioned first embodiment is that the screwing method is the central welding of the bottom 122 of the cooking pot 12. A nut 16 is provided for the screw rod 153 in the center of the top surface of the heat collecting ring 15 to be screwed into and fixed; similarly, a proper distance is still reserved between the heat collecting ring 15 and the bottom of the pot 122 . In addition, a safety ring 123 can also be added on the periphery of the bottom of the pot 122 .

third embodiment

As shown in Fig. 11 and Fig. 12, it is a three-dimensional exploded view and a full cross-sectional combination view of the inner pot of the third embodiment. The difference between this example and the aforementioned first embodiment is that more than one heat collecting ring 15 can be stacked and combined, for example The accompanying drawings reveal that the upper, middle and lower heat-gathering rings 15a-15c are overlapped and combined, but the central screw hole 151 of the lower heat-gathering ring can be screwed with the screw 14, while the centers of the middle and upper two heat-gathering rings 15b, 15c are connected by Holes 154 pass through for bolts 14. After these three heat gathering rings 15 overlap, all through holes 152 can be aligned up and down, so that when the fire burns, the through holes reach the bottom of the pot 122. The heat ring 15a is only the bottom one, and the other heat collecting rings 15b, 15c are not provided with screw holes. This design not only facilitates quick assembly or disassembly, but also makes the through holes 152 of the three heat collecting rings easy to align.

Furthermore, the heat-gathering ring 15 can increase or decrease the amount depending on the type of food and the length of cooking time, which has the same function as a weight; It is enough to achieve the heating effect of increasing temperature, and it can also achieve the effect of keeping warm for a long time. If several heating rings 15 are used, it will cause overcooking of mung beans; Two or more heat-gathering rings 15 must be used to speed up the temperature increase and shorten the simmering time. If only one heat-gathering ring is implemented, not only the temperature increase is too slow, but the simmering time will also be prolonged; so Appropriate selection of the quantity of the heat-gathering rings 15 is helpful to implement simmering and save more energy.

Fourth embodiment

As shown in Fig. 13 and Fig. 14, it is a three-dimensional exploded view and a full sectional view of the inner pot of the fourth embodiment. The difference between this example and the aforementioned third embodiment is that the upper and lower two heat rings 15 are supplied with a central perforation 154. The bolt 14 passes through, and then a nut 17 is screwed at the bottom of the screw rod 14; Secondly, the screw cap 17 protrudes under the heat collecting ring 15, so the cooking pot 12 cannot be placed directly on the table; but when the safety ring 123 is provided under the cooking pot 12, the cooking pot 12 can be moved to the table .

fifth embodiment

As shown in Fig. 15 and Fig. 16, it is a three-dimensional exploded view and a full sectional combined view of the inner pot of the fifth embodiment.

Sixth embodiment

As shown in Fig. 17 and Fig. 18, it is a three-dimensional exploded view and a full cross-sectional combination view of the inner pot of the sixth embodiment. The difference between this embodiment and the previous example is that the safety ring 125 is not integrally formed with the cooking pot 12, but is formed with The thin-shaped safety ring with thin wall thickness is combined with the circumference of the pot bottom 122 by welding technology, and the safety ring made of lead-aluminum alloy is provided with a plurality of protruding retaining edges 1251, and the inner wall is provided with a plurality of reinforcing ribs. Out of the ribs 1252; because the safety ring 125 is thin, the heat dissipation function is better than that of the thick safety ring 123 disclosed in FIG.

Seventh embodiment

As shown in Fig. 19 and Fig. 20, it is a three-dimensional exploded view and a full cross-sectional combination view of the cooking pot of the seventh embodiment. The difference between this embodiment and the previous embodiments is that the inner wall of the fixing ring 123 under the bottom of the pot 122 has internal threads. 126, which can be screwed together with the heat-gathering ring 15' having external threads 156 on the outer edge, so that the heat-gathering ring 15' is hidden in the safety ring 123; at the same time, the fixed ring 123 is provided with a plurality of air holes 128 to facilitate combustion When air convection is generated, the fixing ring 15 ′ is not only provided with through holes 152 , but also provided with guide holes 157 on its periphery.

Secondly, when the heat-gathering ring 15 is implemented with several overlaps, the outermost thread 156 needs to be provided on the lowermost heat-gathering ring 15' to be screwed with the inner thread 126 of the fixed ring 123, while the other heat-gathering rings 15 The outer edge does not have external screw teeth.

The heat collecting rings 15, 15' are also provided with a plurality of perforations 152.
