Description

New anti-overflow pan and anti-overflow temperature control scheme and implementation method thereof

[0001] First, the name of the invention

[0002] A new anti-overflow pan and anti-overflow temperature control scheme and an implementation method thereof.

[0003] Second, the field

[0004] The invention belongs to the field of household appliances, and in particular relates to a kitchen cooker.

[0005] Third, the background art

[0006] Background Art has the following four types:

[0007] (a) Japanese microcomputer rice cooker.

[0008] (2) Natural anti-overflow pan, patent number: CN 2427154Y (2001-03-15, Hong Wenming).

[0009] (3) Wind-proof spill-proof pot, International Publication No.: W0 01/26518 A1 (2001-04-19, Hong Wenming).

[0010] (iv) New concept pot, domestic publication number: CN 102232790 A (201 1-11-9, Hong Wenming).

[0011] The above (1) background art has the following defects: (1) Before 2235, the Chinese people's anti-overflow method when cooking liquid foods is to open the lid, and at the same time, the bottom of the pot is adjusted to reduce the firepower to reduce the inside of the pot. The temperature of the boiling liquid food, so as to achieve the purpose of anti-overflow. We call this method of anti-overflow "lowering the temperature", which is a way of no solution, not an anti-overflow technology. Japanese microcomputer rice cooker technology relies on the computer chip program to control the temperature of the liquid food in the pot below the boiling point. There is no original anti-overflow concept that breaks the "lower temperature". It is not an anti-overflow technology, and it is impossible to have overflow prevention. Features. Rice and whole grains must be easily cooked at the boiling temperature (usually 100 °C). Below the boiling point, it takes a long time to get used slowly. Therefore, the specification of the Japanese Matsushita SR-MS183 microcomputer rice cooker clearly requires: "porridge 1~3 hours; stew 1~4 hours". The experiment proves that the porridge and boiled soup are half-pot or small half-pot. The heating time is "1~3 hours, 1~4 hours". It is not possible to automatically adjust the heating time according to the amount of food, and must cook for 3 hours. Porridge, 4 hours of soup, heating time is in place to be able to taste. There is no anti-overflow function, and the design method of unscientific heating time is destined. It takes too long to consume too much energy and wastes energy seriously. (2) When boiling rice, the soup will flood the lid and stick to the lid. If you use a steamer, the boiling water will flow into the steamer, stick to the food, need to be scrubbed, troublesome, wasteful, unsanitary; (3) The amount of boiled liquid food is limited by the scale, can only cook half pot, the ratio of rice to water It must also be just right, otherwise it will still overflow the pot; the problem is that, even if it is used in accordance with the requirements of the product manual, there will still be juice pouring onto the lid, sticking to the lid, need to be scrubbed, troublesome, wasteful, unsanitary; ) Not suitable for cooking semi-liquid foods. The temperature of the liquid food in the pot must be controlled below the boiling point. Semi-liquid foods such as strips and dumplings take a long time to be able to slowly ripen one by one and become smashed. The above-mentioned various defects are rooted in: There is no breakthrough in the original anti-overflow concept of "lowering temperature", so it is impossible to have an anti-overflow function, resulting in a serious waste of time and energy, and it is urgent to break through.

[0012] The above (2) and (3) background technologies have the following common defects: (1) The anti-overflow function is limited, and is limited to cooking very thin liquid foods. If it is a thicker liquid food, it will overflow when it starts to boil; (2) The manufacturing method has the following defects: 1 Many liquid foods need to be repeatedly opened after the boiled water to add water, feed, stir, and observe. The air ducts and air blowing holes of the two background technologies are made by using the lid of the lid. During the boiling process of the liquid food, the wind direction of the air blowing hole immediately leaves the pot mouth when the lid is opened, and the anti-overflow function is lost; Steamers cannot be used for liquid foods, because the wind ejected from the spray holes of the lids will be blocked by steamers and foods, and cannot be blown into the boiling liquid food in the pot, thus losing the anti-overflow function; (3) "New generation computer chips The three design methods have a common flaw: only the empty noun concept, no specific implementation and implementation methods, no systematic programming data, no chip programming, and no industrial production. The above-mentioned various defects are rooted in: Because the manufacturing method of the whole machine and the design method of the anti-overflow temperature control scheme and its implementation method have various defects, the anti-overflow function is not perfect, and it is impossible to carry out industrial production, and there is no promotion value.

[0013] The above (4) background art has the following drawbacks: (1) Defects of the variable direction fan: 1 The variable direction fan outlet duct is a 90 degree arc-shaped elbow, and the wind is blown before the movable duct It must be turned 90 degrees, the wind is weakened by the resistance, and the anti-overflow effect is reduced. 2 Install the variable direction fan on the inner wall of the rear part of the pot body, which is too far from the center of the inner pot to weaken the wind and reduce the anti-overflow effect. 3 The installation does not closely match. It is easy to loosen and reduce the practical performance; 4 The buckle of the variable direction fan outlet and the inlet of the movable air duct is too small, which is easy to loosen, leak, reduce the wind and reduce the anti-overflow effect. The above-mentioned defects have led to the fact that the technology is still limited to only very thin liquid foods, and if the thicker liquid foods are boiled, they will overflow. (2) Defects of the movable duct: 1 The movable duct is not fastened on the carrier, and it will shake when working. The wind from the jet hole is offset from the center of the inner pot to reduce the anti-overflow effect; 2 movable duct The blast hole is higher than the inner pot mouth. When the lid is covered, the sealing ring and the pressing ring of the lower layer of the lid completely block the wind emitted from the blast hole, resulting in complete loss of the overflow prevention function. Therefore, when the liquid food is boiled, the lid cannot be covered, which is neither hygienic nor wastes energy due to the large heat dissipation area and prolonged heating time. (3) Defects in the design method of using two thermistors (temperature sensors) respectively fixed to the lower layer of the outer pot and the lower layer of the lid: 1 causes the temperature signal obtained by the single chip to be chaotic, and the stability of the anti-overflow function is reduced. 2; The amount of cooked food in the pot is more or less, the temperature difference measured by the thermistor is about 3~15 °C, because the temperature difference between the cooked food and the thermistor in the pot is irregular. According to the cycle, and the variables vary greatly, chip programming cannot be performed, which makes it impossible to design the anti-overflow temperature control scheme and its implementation method, and it is impossible to carry out industrial production. (4) Defects of the operation panel: 1 is a numeric button, the meaning is fuzzy, which is not conducive to practical operation; 2 button "2" The function is very easy to overflow when boiling thick liquid food, it is not desirable; 3 button "3" function, time and power consumption is not good, not desirable; 4 lack of soup, cooking, heating and other function buttons. The above-mentioned various defects are rooted in: Because the manufacturing method of the whole machine and the design method and implementation method of the anti-overflow temperature control scheme have various defects, the anti-overflow function is not perfect, and industrial production cannot be performed, and there is no promotion value.

[0014] Fourth, the purpose of the invention

[0015] The defects of the above four background technologies are rooted in: the manufacturing method of the whole machine and the design method of the anti-overflow temperature control scheme and the implementation method thereof, and there is no breakthrough in the original anti-overflow concept of "reducing the temperature" and there are various defects. Therefore, there is no anti-overflow function and it causes serious waste of time and energy, or the anti-overflow function is not perfect and cannot be industrialized, and there is no promotion value.

[0016] The object of the present invention is to eliminate the various defects of the above four background technologies, to break through the "reduction of temperature" original anti-overflow concept and the background technology of the whole machine manufacturing method and the anti-overflow temperature control scheme design method and implementation method thereof And propose a new technical solution to achieve the ideal all-round anti-overflow function, implement a scientific heating method, and fully and repeatedly use energy to achieve anti-overflow, energy saving, time saving, hygiene, convenience, and stable performance.
