Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention more clearly understood, the present invention will be described in further detail with reference to the accompanying drawings and detailed description. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the scope of the present invention is not limited by the specific embodiments disclosed below.

An inner pot and a cooking appliance according to some embodiments of the present invention will be described with reference to fig. 1 to 17.

Example one

An inner pan 1, comprising: and a pot body 11. Wherein, the pot mouth 12 of the pot body 11 is shaped like a square, as shown in figure 1, figure 3, figure 7 and figure 10. The area of the pot opening 12 is greater than or equal to the area of the reference circle 14, and as shown in fig. 4 to 6, the reference circle 14 is a square inscribed circle with the distance between the two long sides of the pot opening 12 as the side length.

The utility model discloses the embodiment of the first aspect provides an interior pot 1, will interior pot 1's pot mouth 12 change the class square by traditional circular, under the unchangeable circumstances of 12 area of pot mouth, be favorable to dwindling whole cooking utensil's preceding back size and/or left and right sides size to be favorable to reducing cooking utensil's volume, be favorable to realizing the miniaturization of cooking utensil such as electric rice cooker, and then improve the space utilization in kitchen, be favorable to satisfying user's demand.

Specifically, since the conventional cooking devices such as rice cookers generally have a circular inner pan 1 and the pan mouth 12 is generally the largest in area, the shape and size of the pan mouth 12 of the inner pan 1 largely determine the overall shape and size of the cooking device. Because kitchen space and mesa are generally square, circular or approximate circular cooking utensil place can occupy the square space who uses its front and back size and left and right dimensions as the border, as shown in fig. 5, four corners (being the shadow part in fig. 5) of square space can't place other cooking utensils because the shape is irregular and the volume is less relatively, therefore can waste certain space, lead to the space utilization in kitchen lower, and cause putting of kitchen article not neat enough, arouse the visual experience of disorder easily. Accordingly, cooking appliances are increasingly made in a square-like shape, but this results in an increase in volume of the cooking appliance, an increase in cost, and a large space occupation.

The shape of the inner pot 1 is improved, the miniaturization problem of cooking appliances such as an electric cooker is solved through the technical innovation of the inner pot 1, and meanwhile, the using volume of the inner pot 1 is not reduced. Specifically, in the present embodiment, the pot opening 12 of the inner pot 1 is designed to be substantially square, and the area of the square pot opening 12 is greater than or equal to the area of an inscribed circle of a square with the distance between two long sides of the square pot opening 12 (i.e., the length of the short side) as the side length as a reference. Because square or quasi square of the same area compares with circular, the size and/or preceding back size of the square or quasi square will be smaller than circular, therefore design like this is favorable to reducing the size and/or preceding back size of the left and right sides of the pot mouth 12 under the prerequisite that guarantees the area is unchangeable, and then reduce the holistic size and/or left and right sides size of cooking utensil, this is equivalent to improving the space utilization of interior pot 1 in the cooking utensil, thereby reduced cooking utensil's whole volume, be favorable to the miniaturization of cooking utensils such as electric rice cooker, the volume of interior pot 1 has been guaranteed again simultaneously.

In other words, referring to fig. 6, after the inscribed circle of the square is improved to be similar to the square, the area of the shadow part is reduced, so that the wasted space is effectively reduced, the area utilization rate of the inner pot 1 is improved, the improvement of the space utilization rate of the kitchen is facilitated, the arrangement of kitchen articles is facilitated to be tidy, and the visual experience of a user is improved.

For the convex quadrilateral-like structure shown in fig. 6, the area of the pan opening 12 is larger than that of the reference circle 14. For the case that a part of the quasi-square shape is recessed into the reference circle 14, a part of the quasi-square shape is protruded out of the reference circle 14, and the areas of the two parts are equal, the area of the pot opening 12 is equal to the area of the reference circle 14. Such as: on the basis of fig. 6, four sides of the square are appropriately bent inwards, so that a part of the square is recessed into the inscribed circle, the pot opening 12 forms a concave-like quadrangle, and the area of the recessed part is equal to the area of the part outside the reference circle 14. This is equivalent to slightly contracting the pot opening 12 by a certain extent on the basis of the square shape shown in fig. 6, thereby being beneficial to reducing the left and right size and/or the front and back size of the pot opening 12, being beneficial to the miniaturization of cooking appliances such as electric cookers and the like, and simultaneously ensuring the volume of the inner pot 1.

It is to be understood that "square-like" in this application means substantially square, i.e.: rather than being strictly square and rectangular, the whole is square, having roughly two sets of opposite sides. Such as: the corner part of the quasi-square shape can be provided with a round corner or a chamfer, the side of the quasi-square shape can comprise line types such as straight lines, arc lines, curves and the like, and the arc lines and the curves can be outwards bent and convexly extended (namely, bent and convexly extended towards the direction far away from the central axis of the pot opening 12) and can also be inwards bent and convexly extended (namely, bent and convexly extended towards the direction close to the central axis of the pot opening 12). The central axis of the pot opening 12 refers to a straight line passing through the center of the reference circle 14 and perpendicular to the plane of the pot opening 12.

Wherein, the side lengths of the two groups of opposite sides of the quasi square shape can be equal, so the pot opening 12 is approximately square, and the side lengths of the two groups of opposite sides of the quasi square shape can also be unequal, so the pot opening 12 is approximately rectangular. When the pot opening 12 is approximately square, the distance between the two long sides is the distance between any pair of opposite sides. When the pot opening 12 is substantially rectangular, the distance between the two long sides is the distance between the two long sides corresponding to the rectangle. The pitch of a pair of opposite sides of a square-like shape refers to the maximum pitch between two corresponding dots in a set of opposite sides.

Specifically, pan body 11 includes: an upper body section 111 and a lower body section 112, as shown in fig. 1 and 2. Wherein, the cross section of the upper section 111 of the pan body is similar to a square, as shown in figure 1. The lower section 112 of the pan body is connected with the lower end of the upper end of the pan body.

The pot body 11 includes pot upper segment 111 and pot body hypomere 112, the cross section of pot body upper segment 111 also is type square, then the shape of pot body upper segment 111 and the shape adaptation of pot mouth 12, this machine-shaping of being convenient for, and be favorable to increasing the volume on 1 upper portion of interior pot, then under the prerequisite of same volume, be favorable to increasing the shape kind of pot body hypomere 112, also be favorable to reducing the height of interior pot 1, and then reduce cooking utensil's height, further be favorable to realizing the miniaturization of cooking utensils such as electric rice cooker.

Further, the lower section 112 of the boiler body is connected with the upper section 111 of the boiler body through a transition section 113 in a circular arc manner, as shown in fig. 1 and 2.

The lower pot body section 112 and the upper pot body section 111 are connected through the transition section 113 in an arc manner, and the contour line of the longitudinal section of the transition section 113 is an arc, so that the upper pot body section 111 gradually transits to the lower pot body section 112 through the transition section 113, the shape of the lower pot body section 112 is conveniently and reasonably designed as required, and the whole inner pot 1 is more attractive.

Further, the upper end of the pan body 11 is turned outwards to form a pan rim 13, as shown in fig. 1 and 2.

The upper end of the pot body 11 is turned outwards to form a pot edge 13, so that the inner pot 1 is supported by the outer pot of the cooking utensil conveniently, and the inner pot 1 is convenient to take and place. Wherein the inner and outer edges of the pan rim 13 form two concentric rings resembling a square. Because the width of the pan edge 13 is narrower, and the shape of the pan edge 13 is the same as that of the pan opening 12, in order to facilitate the illustration of the shape of the pan opening 12, the contour line of the pan opening 12 can be equivalent to the outer edge of the pan edge 13.

Further, the contour line of the pan opening 12 includes four first arc lines 121 and four second arc lines 122, as shown in fig. 3, the four first arc lines 121 and the four second arc lines 122 are distributed in a staggered manner and are sequentially connected end to end. The radius of the first arc line 121 is smaller than that of the second arc line 122, and the four first arc lines 121 and the four second arc lines 122 are curved and protruded towards the outer side of the pot opening 12.

In the scheme, the contour line of the pot opening 12 is formed by alternately connecting eight circular arcs to form a similar square with four sides properly protruding outwards, and the line is soft and attractive.

It is understood that the four first arc lines 121 and the four second arc lines 122 are curved to protrude toward the outside of the pot opening 12, which means to protrude in a direction away from the central axis of the pot opening 12.

Of course, the shape of the contour line of the pot opening 12 is not limited to this, and may also include a straight line or a curved line with more dimensions, which may be adjusted as required in the actual production process.

Specifically, the lower section 112 of the body is generally cylindrical or hemispherical, as shown in FIG. 1.

The lower section 112 of the pot body is cylindrical or hemispherical as a whole, the cross section of the lower section 112 of the pot body is circular, and thus the pot body 11 is in a shape of a circle above and below the whole, and the existing structure matched with the lower part of the inner pot 1 does not need to be greatly improved, thereby being beneficial to reducing the product cost.

Further, the lower end of the lower section 112 of the pan body is opened, and the opening is covered by the pan bottom of the inner pan, wherein the lower section 112 of the pan body and the pan body can adopt a smooth connection mode, a fillet connection mode and the like, so that the lower part of the lower section 112 of the pan body can be properly bent inwards and inclined.

Example two

The difference from the first embodiment is that: the lower part 112 of the pan body is in a quadrangular prism shape as a whole, as shown in fig. 7 to 9.

The lower section 112 of the pan body is quadrangular integrally, and the cross section of the lower section 112 of the pan body is square-like, so that the whole pan body 11 has basically consistent upper and lower shapes, is convenient to machine and form and is more attractive.

EXAMPLE III

The difference from the first embodiment is that: the lower part 112 of the pan body is an inverted cone as a whole, and the cross-sectional area of the lower part 112 of the pan body is gradually reduced from top to bottom, as shown in fig. 10 to 12.

The whole body lower segment 112 is the back taper, and the cross-sectional area of body lower segment 112 from top to bottom reduces gradually, and then body lower segment 112's volume is less, and this helps little rice volume culinary art (for example cook a small amount of rice), is favorable to improving the height of eating material height and water to be favorable to eating the material fully to absorb water, and then improve the culinary art effect.

Wherein, the lower section 112 of the pan body can be in the shape of an inverted cone or an inverted quadrangular pyramid.

Specifically, in the case where the lower body section 112 is an inverted cone as a whole, an included angle α between a tangent line (as shown in fig. 8) of an outer edge or an outer edge vertex of a longitudinal section of the lower body section 112 and the central axis of the inner pot 1 is 30 ° or less.

For the case that the lower section 112 of the pan body is integrally in the shape of an inverted cone, the angle between the longitudinal section of the lower section 112 of the pan body and the central axis is less than or equal to 30 degrees, so that the inner pan 1 can be prevented from being too short or the pan opening 12 can be prevented from being too large due to too large included angle. By adjusting the angle, the inner pots 1 with the same pot mouth 12 and the same height can have different volumes, so that the inner pots 1 with different volumes can share the same cover plate 63, steamer and other accessories, new parts are reduced, and the cost is reduced.

Of course, the included angle is not limited to the above range, and can be adjusted as required in the actual production process.

It will be appreciated that for embodiments in which the cross-section of the lower body section 112 is circular or square-like and the lower body section 112 extends in a vertical direction, the angle α between the longitudinal section of the lower body section 112 and the central axis of the inner pan 1 is then 0 °.

Of course, the lower body section 112 may also be tapered in a non-tapered manner, for example, a longitudinal section of the lower body section 112 may extend downward and inward in a curved manner.

Example four

On the basis of any of the above embodiments, further, the inner side wall of the pot body 11 is convexly provided with a supporting step 114, as shown in fig. 1, fig. 2, fig. 10 and fig. 11.

The supporting step 114 is convexly arranged on the inner side wall of the pot body 11, so that accessories such as a food steamer and a grate can be conveniently supported, and compared with the scheme that the traditional food steamer is hung on the pot edge 13 of the inner pot 1 through a flanging, the coating on the pot opening 12 of the pattern scraping pot can be prevented.

Wherein, the supporting step 114 is located between the upper pot body section 111 and the lower pot body section 112, as shown in fig. 1, fig. 2, fig. 10 and fig. 11.

The supporting step 114 is located between the upper pot body section 111 and the lower pot body section 112, so that the supporting step 114 is formed by deformation between the two, for example, the supporting step 114 is formed by the transition section 113. Therefore, the inner side wall of the pot body 11 does not need to be processed independently, so that the processing difficulty is favorably reduced, the production efficiency is further improved, and the production cost is reduced.

In particular, transition section 113 of pan body 11 forms support step 114.

The transition section 113 of the pot body 11 forms the supporting step 114, and the inner side wall of the pot body 11 does not need to be processed, so that the processing difficulty is favorably reduced, the production efficiency is further improved, and the production cost is reduced. Meanwhile, the transition section 113 has both a transition function and a supporting function, and the integration level of the product is improved.
