Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the present invention. Apparently, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the protection scope of the present utility model.

As shown in Fig. 1, it is a front view structural diagram of the existing dual gallbladder electric cooker with two pot covers open on the market, wherein h is the height of the pot cover 3, and k is the middle surface to the first hinge axis 4 or the second hinge axis 5 center distance, E is the lid opening gap, e is the lid closing gap, and x is the inward variation of the pot lid 3. It can be known that when using a double-tank rice cooker for cooking, the area between the inner pots 2 on both sides has heat sources on both sides, unlike other surfaces that can dissipate heat in a timely manner, and it is easy to cause heat to concentrate in the middle to form a thermal imbalance. In addition, the inner pot needs to bear and the weight of the food, the surface of the middle frame will sink; when the sinking of the middle frame 8 is f, the concave angle of the middle frame 8 is g, and the inward slope angle of the pot lid 3 is also g, according to the trigonometric function 1/2 (e-E)=hsin(g), f=ksin(g), at this time E=e-2fh/k, if the value of h is 3-5 times of k, E=e-(6～10)f, so , as long as the middle frame 8 sinks slightly f=0.5, E=e-(3~5); the design size of e must be greater than 3mm, otherwise E is a negative number, and the two pot lids 3 interfere (commonly known as fighting), thus It can be seen that the smaller the deformation of f is, the less likely it is to interfere.

In order to solve the problem of interference between the two pot covers of the existing double-tank electric cooker, as shown in Figure 2-9, the utility model provides a double-tank electric rice cooker, which includes a pot body 1, two inner pots 2 located in the pot body 1, and The two pot lids 3 that are closed on the two inner pots 2, wherein: the rear ends of the two pot lids 3 are rotatably connected with the pot body 1 through the first hinge shaft 4 and the second hinge shaft 5 respectively. Under the opened state, a V-shaped gap is formed between the two pot covers 3, and the V-shaped gap gradually increases from the rear end of the pot cover 3 to the front end of the pot cover 3. At this time, as long as the gap value of the V-shaped gap is set reasonably The mutual interference of the two pot covers 3 can be avoided.

Specifically, as shown in FIG. 3 , in one embodiment, the first hinge axis 4 and the second hinge axis 5 are in the shape of an "eight" on the horizontal plane, the first hinge axis 4 is arranged obliquely upward, and the second hinge axis 5 is inclined. Set downwards, the inclination angles of the first hinge axis 4 and the second hinge axis 5 are both G. As shown in Figure 4, in other embodiments, the first hinge axis 4 and the second hinge axis 5 are in the shape of an "eight" on the vertical plane, the first hinge axis 4 is arranged obliquely upward, and the second hinge axis 5 is inclined Set downwards, the inclination angles of the first hinge shaft 4 and the second hinge shaft 5 are both G; The problem of interference also ensures the simplicity of the overall structure; and under the condition that the middle frame 8 does not sink, when the pot cover is opened 90°, the inclination angle of the pot cover 3 is just G, and at this time, the opening gap E= e+2hsin(G).

Specifically, as shown in Figure 6, the middle frame 8 is arranged between the two liners 2. When the middle frame 8 sinks f and deforms, the inclination angle of the middle frame 8 is g. At this time, only the first hinge axis 4 and the inclination angle G≥g of the second hinge axis 5 can prevent the pot lids 3 from interfering with each other. At the same time, as shown in Figure 5, in order to further prevent the pot lid 3 from deforming, add transverse ribs 7 .

Specifically, as shown in Figure 7, a support plate 6 is also provided between the two inner tanks 2, and the support plate 6 supports the middle frame 8 to prevent and reduce the sinking deformation of the middle frame 8, reduce f, and naturally reduce the pressure of the pot. The risk of interference from the cover 3; at the same time, the support plate 6 is also a heat insulation plate, which reduces the heat transfer between the two inner pots 2, avoids the heat exchange between the left and right inner pots, and affects the cooking effect.

In addition, as shown in Figures 8-9, in order to simplify the size of the rice cooker and reduce the gap between the lids, the inner pot 2 of the present utility model is a D-shaped inner pot, including straight sides a, b, and a semicircle R, wherein the straight side a It is connected with the two straight sides b through arc chamfering R1, and the two straight sides b are connected with the semicircle R. The value of the semicircle R can be selected according to the liter of the inner tank 2. For example, for a 1.5L inner tank, the semicircle R can be Choose 170mm, the value range of arc chamfer R1 is 8≤R1<R, when R1=R, the liner is circular, straight side a=2(R-R1), that is, the length of straight side a is equal to The value of the semicircle R minus twice the value of the arc chamfer R1; at the same time, the inner tank also has an inner tank flange c, and the value range of the inner tank flange c is 8-15mm; since the inner tank 2 is D-shaped, In the utility model, the straight side a is designed as an adjacent surface. In order to simplify the overall size of the product, the adjacent space is designed to the minimum as much as possible, which forms a narrow space with a length of a and a width of d. The width d is determined by the closing gap e+outer cover Thickness + thickness of the inner cover + flanging of the liner + necessary air-avoiding composition, after calculation d = e + (28 ~ 40).

Based on the above description, in the case that the interference between the two pot covers can be solved and the size of the rice cooker can be simplified to the greatest extent to reduce the gap between the pot covers, preferably, the lid closing gap e=0.5~5mm, and the lid opening gap E=3~15mm, The inclination angle of the first hinge axis and the second hinge axis is G=0.5-5°, d=28.5-45, and the straight side a of the D-shaped liner is a=2 (R-R1).

The double-tank rice cooker of the utility model solves the problems of interference between pot lids caused by product deformation, thermal interference between multiple inner tanks, uneven heat dissipation, etc., and simplifies the size of the product to the greatest extent, and fully considers the product The precision of the process and the changes that may occur in the case of thermal interference and uneven heat dissipation ensure that the structural performance of the product is not affected. Under the same capacity, it achieves the smallest volume, improves the user experience, and has a unique and beautiful appearance. .

The utility model has been further described above with the help of specific embodiments, but it should be understood that the specific description here should not be interpreted as limiting the essence and scope of the utility model. Various modifications made to the above-mentioned embodiments all belong to the protection scope of the present utility model.
