Specific embodiment

Below in conjunction with the attached drawing in the embodiment of the present application, technical solutions in the embodiments of the present application carries out clear, complete Whole explanation.

Embodiment one:

A kind of uniformly heated cooking apparatus is present embodiments provided, as shown in FIG. 3 to 7, the cooking apparatus includes pot Body 100 and lid (not shown), the pot body 100 are equipped with heat-generating disc 110, the top of the heat-generating disc 110 be equipped with Its liner 120 being bonded, the liner 120 are revolution shape, and the heat-generating disc 110 is equipped with and heat-generating disc central axis X-X Concentric inner ring heating region 112 and outer ring heating region 113, wherein between the inner ring heating region 112 and liner 120 Equipped with the first gap delta, the outer ring heating region 113 is bonded with 120 outer surface of liner.Specifically, the heat-generating disc 110 For planar disc, the center of heat-generating disc 110 is additionally provided with the through-hole 111 for temperature element to be arranged, is set to heat-generating pipe in heat-generating disc 110 114, fever pipe diameter D1 and generate heat disk diameter D2 ratio range be 0.45~0.8, the liner 120 include bottom wall 121 with Side wall 122 is equipped with the First Transition portion 123 of arc between the bottom wall 121 and side wall 122.

It is well known that initial rice moisture content makes the water rice ratio of rice usually in 1.1:1 usually 13 ~ 15% or so Left and right, the cooking process of rice is broadly divided into water suction, boils and three phases of cooking rice over a slow fire, and in the water suction stage, rice immersion is gone forward side by side The certain temperature of row is heated to promote its water suction, and rice moisture content is generally capable of up to 30% or so after the water suction stage, this is cooked Prepare food early period when liner in rice water state as shown in Figure 1, due to electric cooker in the prior art heat-generating disc heat cohesion effect, institute It is high to lead to the area Tu1Zhong I temperature, thus the rice absorption speed in the area I is fast, and the rice absorption speed in the area II is slow；As temperature continues After raising reaches boiling stage, the moisture content of rice can reach 60 ~ 63% or so (being still not up to the limiting value of rice moisture content)； Enter after boiling stage and cook rice over a slow fire the stage, the circulating water in liner gradually reduces, at this time rice water state such as Fig. 2 institute in liner To show, flowing water gradually focuses on the bottom in the area I, although the top in the region has been detached from the immersion of water at this time, due to Heating and continuous progress, the water of the region lower part can be brought on come so that the rice in the area I is not having completely by bubble floating There is the water suction that can also continue before water, since, by arc transition, the meter Ji Ben in the area II is de- between the bottom wall and side wall of liner Immersion from water is also just enough brought to the rice region on upper layer, so that in the rice in the area II without water energy by bubble floating Moisture is generally fewer than the area I, and it is partially wet soft often to will appear middle section so as to cause its rice made, and marginal portion Firmly raw phenomenon partially.

Secondly, fill the liners of meter aqueous mixtures during heating, exterior bottom wall due to directly being contacted with heat-generating disc, Temperature highest, expanded by heating, and inner wall, due to contacting with rice aqueous mixtures, temperature is lower, forms the biggish temperature difference between the two, To make expansion amplitude on the outside of liner be noticeably greater than inside, make liner at the bottom arching, liner section from U-typed be in " V " Trend, the contact area of liner at the bottom and heat-generating disc reduces, and contact position is shifted to the centre of heat-generating disc, into one Step causes heating uneven.

Again, the bonding position of traditional heat-generating disc and liner can cause because of the unstability of respective manufacturing process Occur at random within the scope of entire heat-generating disc, temperature is high at the position that liner is bonded with heat-generating disc, heats up most fast, so that different patches Coincidence sets heat transfer to liner center (center location) time difference, causes to form biggish control mistake in process control Difference.

The technical program on heat-generating disc by being arranged inner ring heating region and outer ring heating region, wherein outer ring hot zone Domain is bonded with liner, and the first gap is provided between inner ring heating region and heat-generating disc, is needed when transmitting heat by the gap Air transmitted so that on liner with heat-generating disc outer ring heating region fitting band of position temperature be higher than with inner ring it is corresponding The band of position, so that absorb heat of the central area of liner within the unit time is less than First Transition portion and its near zone Heat is absorbed, and then is formed on liner and is heated strong area and heat weak area, is especially risen in water suction in the cooking process of rice Liner side temperature increases fast when thermophase, promote the region rice its absorb water in advance, avoid the culinary art later period from leading due to water shortage The problem for causing rice partially firmly raw, the rice uniformity that final cooking comes out are preferable.In addition, having inner and outer ring hot zone after improved The heat-generating disc in domain can make the maximum temperature position of liner be limited in the position for having certain distance range with liner center, thus Reduce the control error of cooking process.In addition, the ratio range for the pipe diameter D1 and fever disk diameter D2 that will also generate heat is limited to 0.45~0.8, if the ratio is too small, then the cohesion effect of heat-generating disc can be made more obvious, if the ratio is too big, The temperature that then will lead to inner ring heating region is too low, can not form the strong area of the substantially invariable heating of the temperature difference on liner and heat weak Area.

Further, as shown in figure 4, the first gap delta range is 0.3~1.5mm.

As a kind of specific implementation of the present embodiment, the value of first gap delta is constant.Specifically, described First gap delta value is any one in 0.5mm, 0.6mm, 0.7mm, 0.8mm, 0.9mm, 1mm.Preferably, described first Gap delta takes 0.6mm.

As another specific implementation of the present embodiment, the value of first gap delta is variation, that is to say, that The distance between any point and liner are in the range of 0.3~1.5mm on the inner ring heating region.

If first gap is less than 0.3mm, liner or heat-generating disc temperature distortion may cause, so that liner and inner ring Heating region fitting, to be bonded, spot temperature is also higher, causes the culinary art of rice ineffective；If first gap is greater than 1.5mm, may cause the inner ring heating region thickness deficiency of heat-generating disc and intensity is inadequate, and also will cause inner ring heating region can not Timely conduct heat to liner.By setting 0.3~1.5mm for the first gap delta range, it can guarantee inner ring heating region It effectively conducts heat to liner, and forms the strong area of the substantially invariable heating of the temperature difference on liner and heat weak area, and then guarantee each The rice uniformity and consistency cooked is preferable.

As a kind of specific implementation form of the present embodiment, first gap by inner ring heating region least radius It is gradually reduced to maximum radius.To further decrease the cohesion effect of heat-generating disc, so that it is basic to form the temperature difference on liner The strong area of constant heating and the weak area of heating.

Further, as shown in figure 3, the arc radius r in the First Transition portion 123 is with liner radius R ratio range 0.45~0.95。

The ratio is too small, namely in the case where liner constant-radius, and the arc radius in the First Transition portion is too small, Or the ratio is too big, namely in the case where liner constant-radius, the arc radius in the First Transition portion is too big, all can So that the arc area insufficient height in the First Transition portion, when rice cooking process in liner each position height of water level deviation Smaller, peripheral portion rice water suction corresponding with outer ring heating region is excessive and too rotten in liner, influences the quality of rice.By institute It states ratio to be limited between 0.45~0.95, can guarantee that the arc area in the First Transition portion keeps certain height, cook The water level in liner central area and First Transition portion forms certain deviation during preparing food, to keep the rice in each region uniform Property.

It should be noted that the radius of the liner refers to the radius of liner opening portion.

As preferable specific implementation, the arc radius r in First Transition portion and the radius D proportional region of liner are 0.55~0.85。

As a kind of specific implementation of the present embodiment, the bottom wall 121 of the liner 120 is plane.

Since the liner bottom wall area matched with planar disc heat-generating disc is larger, if its bottom wall is also processed into flatness Preferable plane difficulty is larger, and in later period use process, is easily deformed that liner is caused to place jiggly problem. It is set as a curved surface for inner side of liner protrusion by the bottom wall of liner, enhances the intensity of liner bottom wall, reduces stress deformation, and And when reducing placement liner forced area, and concentrate on stress area on the region of annular, guarantee to place steady.Specifically Also set the height of projection h of curved surface to no more than 8mm, if h is too big, it is too high to may cause liner middle height, and real Border upper inner-liner middle portion temperature is lower, causes the rice water suction at middle part insufficient, partially hard so as to cause rice water shortage.

Further, the outer ring heating region 113 is at least partially disposed at the surface of the heat-generating pipe 114.

Since heat-generating pipe is cast in heat-generating disc, the heat-generating disc thinner thickness of heat-generating pipe upper area be may cause It can not completely be filled in time in casting process, to cause defect rate higher.By by the outer ring heating region at least portion It is divided into the top of the heat-generating pipe, so that heat-generating pipe upper area thickness is relatively thick, guaranteeing can be timely in casting process Filling, and make heat-generating pipe and outer ring heating region distance recently, heat-generating pipe generate heat can quickly, timely to outer ring Heating region transmitting.

Further, the ratio range of the width of the outer ring heating region and heat-generating disc radius is 1/3 ~ 2/3.

If the ratio of the width and heat-generating disc radius of the outer ring heating region is too small, then in heat-generating disc constant-radius In the case of, outer ring heating region is relatively narrow, and it is too small to may cause the region area that heat-generating disc is bonded with liner, liner installation less than It can not be formed in liner close to First Transition portion in the case where position and heat strong area；If the width and hair of the outer ring heating region The ratio of hot plate radius is too small, then in the case where heat-generating disc constant-radius, the width of outer ring heating region is too big, may cause The area of inner ring heating region is too small, and it is stable can not to form the temperature difference in the arc First Transition portion region of liner and central area It heats strong area and heats weak area.It is 1/3 ~ 2/ by the limit of the ratio range of the width of the outer ring heating region and heat-generating disc radius 3, the strong area of stable heating can be formed in the arc First Transition portion region of liner and central area and heat weak area, Bu Huiyin For the little deviation of liner placement location and it is impacted.

Further, the ratio of the maximum radius of the inner ring heating region and heat-generating disc radius is greater than 1/4.

In the case where heat-generating disc constant-radius, the inner ring heating region is too small, and will lead to can not be in the arc of liner First Transition portion region and central area form the strong area of stable heating and heat weak area.

As a kind of specific implementation of the present embodiment, as shown in figure 5, the outer diameter of the outer ring heating region is equal to hair The outer diameter of hot plate.
