Detailed Description

Referring to fig. 1 to 5, the electric rice cooker comprises a cooker body 1 and an inner container 2 made of ceramic or glass, wherein a heating plate 3 is arranged at the bottom of an inner cavity of the cooker body 1, the inner container 2 is arranged on the heating plate 3, the bottom wall of the inner container contacts with the heating plate 3 for heat transfer, a heat-conducting metal cylinder 4 is arranged around the peripheral side wall of the inner container 2, and the metal material is preferably aluminum with excellent heat-conducting property or other materials with good heat-conducting effect. The periphery of the heating plate 3 is fixedly connected with the lower part of the heat-conducting metal cylinder 4 and transfers heat to the heat-conducting metal cylinder 4, the heat which is heated by the heating plate 3 and is conducted by the heat-conducting metal cylinder 4 heats the bottom wall and the peripheral side wall of the inner container 2 in an enclosing manner, the heat is relatively uniformly transferred around the inner container, and the heat-conducting metal cylinder 4 only heats the side wall of the inner container 2, so that the plate can be directly processed, the manufacturing process is simple, materials are saved, the die opening is not needed, and the manufacturing cost is greatly reduced.

The utility model can not only heat rice grains from the lower part through the heating plate 3, but also realize the synchronous heating of water with different water level heights through the rapid heat transfer of the heat-conducting metal cylinder 4, so that the rice grains at the upper part and the lower part are heated to the same degree, the curing degree is basically synchronous, the rice is uniformly heated, the rice is more fluffy and full, and the condition that the rice at the lower part is burnt or the rice at the upper part is half cooked is avoided; compare in prior art, under the same power, adopt the utility model discloses technical scheme's rice cooker, the inner bag conducts heat faster more even, and rice is heated ripe fast, can effectively reduce the culinary art time, improves the taste of rice.

The technical effects of the present invention will be described below with reference to the comparative experiment.

The measuring object of "contrast group" is the glass inner bag rice cooker among the prior art, and the measuring object of "experiment group" does the utility model discloses a glass inner bag rice cooker, the test point is got the upper and middle, lower three point of glass inner bag outer wall respectively and is regarded as the temperature monitoring point to every 3 minutes a set of data of intercepting contrast.

In the cooking process of the electric cooker, the rice needs to be heated and absorbed by water, continuously heated, boiled, braised and thermally insulated; the method comprises the steps of heating up rice to absorb water to expand in the initial stage, continuously heating to enable the rice to boil, completely moistening the rice in water in the boiling stage, rolling from bottom to top, fully heating and tending to be mature, entering a stewing stage after the rice can not roll any more when the moisture is less and less, supplementing and curing the rice to enable starch in rice grains to be further fully gelatinized and mature, enabling the rice to be fluffy and full, and finally entering a heat preservation stage to boil the rice to be dry and increase the fragrance of the rice.

Referring to the table above, in the water absorption stage of 0 to 9 minutes, the temperatures of the upper part, the middle part and the lower part of the experimental group are obviously higher than those of the comparative group, which shows that the temperature of the glass liner is quickly raised under the surrounding and heat transfer effects of the heat-conducting metal liner; after entering the continuous heating stage, the lower temperature and the middle temperature of the experimental group are close to boiling at 18 minutes, while the control group can enter at 24 minutes, and the time difference is reflected; when the full boiling stage is reached, namely the lower part, the middle part and the upper part reach the boiling temperature, the experimental group can be finished in 24 minutes, and the comparative group is finished in 36 minutes; as can be seen from the above data, the experimental group took less time to heat to boil, i.e., faster heating, and the experimental group took 51 minutes in total and the comparative group 60 minutes when the braising and warming phases were completed. Therefore, compared with the common electric rice cooker with the glass inner container, the utility model has the advantage that the rice ripening speed is higher.

The bottom burnt phenomenon of the electric cooker during cooking is mainly caused by that rice is burnt due to slow heat conduction caused by overheating of the bottom of the inner container in the stewing stage, and as can be seen from table data, the temperatures of the upper, middle and lower positions displayed by an experimental group are more uniform in the stewing stage, and the phenomena of bottom burnt and top half-cooked are easy to occur due to the obvious temperature difference of the upper, middle and lower temperatures of a contrast group. Therefore, in the process of braising rice, the utility model discloses can conduct bottom heat to upper portion through the lateral wall of heat conduction metal container, avoid the inner bag bottom to gather the phenomenon of sticking with paste the end because of the heat to and upper portion is heated not enough and presss from both sides living, make the whole inner bag outside can tend to thermally equivalent, effectively improve the taste of rice.

As the utility model discloses a preferred scheme, 4 bottoms of heat conduction metal cylinder are turned over and are rolled over and form buckle 41 lock joints in the dish 3 bottoms that generates heat, realize heat conduction metal cylinder 4 and the fixed connection who generates heat and coil 3. The following are three embodiments of pinch plate fixation: firstly, the pinch plate can be pressed on the bottom of the heating disc 3 through the fixing component 5, the fixing component 5 is an installation pressing plate 6, the installation pressing plate 6 comprises a fixing part 61 and a pressing part 62, the fixing part 61 is fixedly connected with the heating disc 3, and meanwhile, the pinch plate 41 is pressed on the bottom of the heating disc 3 through the pressing part 62 from the lower part without further processing on the pinch plate 41 (as shown in fig. 2 and 3); secondly, the fixing component 5 can be a common screw, but a hole needs to be drilled on the pinch plate 41 for the screw to penetrate and be connected with the heating plate 3, and the pinch plate 41 is pressed and fixed by the head of the screw (as shown in fig. 4). Thirdly, the pinch plate 41 is not required to be fixed through the fixing part 5, the heating plate 3 is provided with the through groove 31, the pinch plate 41 extends into the through groove 31 and is buckled at the bottom of the heating plate, furthermore, the pinch plate 41 is provided with the inserting hole 42 which is sleeved on the clamping column 32 protruding at the bottom of the heating plate 3, and the pinch plate 41 and the heating plate 3 are fixed (as shown in fig. 5).

The three embodiments described above are only preferred embodiments of the present application, and are not limitations to the embodiments of the present application, and all technical solutions that achieve the objectives of the present invention by using basically the same technical means should belong to the protection scope of the present invention.
