The liner structure and the cooking appliance according to the embodiments of the present utility model will be described below with reference to fig. 1 to 4, and some embodiments of the present utility model will be described below in detail with reference to the accompanying drawings, where the following embodiments and features of the embodiments may be combined with each other without conflict.

The embodiment discloses a liner structure, which can be particularly applied to cooking appliances such as electric rice cookers, electric pressure cookers and the like.

According to the structure shown in fig. 1-4, the liner comprises a liner main body 1 and a shell 2, wherein the liner main body 1 sequentially comprises a liner lower part 11 and a liner upper part 12 from bottom to top, the shell 2 is sleeved on the circumferential outer side of the liner main body 1, a sealed space 3 for heat preservation is formed between the shell 2 and the liner upper part 12, and the part corresponding to the shell 2 and the liner upper part 12 is bent outwards. Wherein the bending arrangement may be specific to the arcuate segment of travel.

Because the existing liner has the problems of poor heat preservation and heat storage effects, relatively high manufacturing process and relatively high cost, the liner structure in the embodiment can achieve the heat preservation and heat storage effects by arranging the liner main body 1 and the shell 2 and forming the airtight space 3 between the liner upper part 12 and the shell 2 through improving the liner. In addition, the outer shell 2 is arranged in a bending way towards the outer side, so that the volume of the closed space 3 can be effectively increased, and further, better heat preservation and heat storage effects are achieved.

In addition, compared with the existing double-layer liner structure, the liner structure is combined with the shell 2 on the single-layer liner structure, and can be processed by adopting processes such as stamping, and the processing process is simple and reliable, so that the manufacturing cost can be effectively reduced.

Specifically, the liner body 1 sequentially includes a liner lower portion 11, a liner upper portion 12, and a liner edge portion from bottom to top. Optionally, the liner body 1 may be formed by integral stretching and stamping to form a liner lower portion 11, a liner upper portion 12, and a liner edge portion. The housing 2 may also be formed by integral stretching and stamping.

And, can be sleeved into the shell 2 with the inner container body 1 after processing, adopt the processing technology such as the punching press, etc., compound the two together. It should be noted that, the outer shell 2 may be specifically combined with the liner edge portion and the liner lower portion 11 to form an integrally formed whole, and a sealed space 3 with heat preservation and heat storage functions may be formed between the outer shell 2 and the liner upper portion 12.

Also specifically, the liner body 1 and/or the outer case 2 are made of a metal material. Wherein the optional metal material is aluminum, iron, stainless steel or composite metal plate, which can effectively reduce the cost.

Also specifically, the closed space 3 is vacuum-set. In the use process of the vacuum-arranged airtight space 3, heat can accumulate in the airtight space 3 and is not easy to dissipate, so that better heat preservation and heat storage effects are realized. Of course, in other embodiments, the enclosed space 3 may be provided other than in vacuum.

As shown in fig. 1 and 2, the liner upper portion 12 is further curved inward. According to this embodiment, the portions of the liner upper portion 12 and the casing 2 corresponding to the liner upper portion 12 are all arc-shaped, but the arc-shaped bends are different, the arc-shaped structure of the liner upper portion 12 is bent inward, and the arc-shaped structure of the portion of the casing 2 corresponding to the liner upper portion 12 is bent outward, so that the liner upper portion 12 and the casing 2 can form a larger heat-preserving and heat-storing airtight space 3, and the overall heat-preserving and heat-storing effects are further improved. The upper portion 12 of the inner container is integrally curved, and is particularly applicable to an electric rice cooker.

According to fig. 3 and 4, in some other embodiments, the upper liner 12 includes a first liner section 121 and a second liner section 122 from bottom to top, where the first liner section 121 is bent toward the inner side, and the second liner section 122 is vertically disposed. According to the embodiment, the upper portion 12 of the inner container is not completely arc-shaped, but is formed by combining a section of arc-shaped structure and a section of vertical structure, and in practical application, the sealing ring is installed at the opening of the electric pressure cooker, so that the upper portion 12 of the inner container is provided with the upper section 122 of the inner container which is vertically arranged and is matched with the sealing ring in order to prevent interference with the sealing ring, and therefore, the electric pressure cooker or the electric cooker can be particularly applied.

1-4, the thickness of the liner main body 1 is delta 1, wherein delta 1 is more than or equal to 0.5mm; the thickness of the shell 2 is δ2, where δ1 is 0.2×δ2.ltoreq.δ1. Alternatively, the thickness δ1 of the liner body 1 may be specifically 0.5mm, 1mm, 1.5mm, 2mm, or the like, and the thickness δ2 of the outer casing 2 may be specifically 0.3mm, 0.7mm, 1mm, 1.5mm, or the like. According to the embodiment, the thickness delta 1 of the liner main body 1 and the thickness delta 2 of the shell 2 are set to be the thicknesses with the dimensions, so that the composite processing of the liner main body 1 and the shell 2 is facilitated, the cost can be reduced, the strength is enhanced, and better heat preservation and heat storage effects are ensured.

Further, as shown in fig. 1 to 4, the liner lower portion 11 and the outer shell 2 are formed by a composite and integral molding. According to the embodiment, the lower part 11 of the inner container is combined with the outer shell 2 to form a whole, the upper part 12 of the inner container is combined with the outer shell 2 to form a heat-preserving and heat-storing closed space 3, when heating is performed, the lower part 11 of the inner container is contacted with a heating body (such as a heating disc and an IH coil), and when the heating body works, the lower part 11 of the inner container is combined with the outer shell 2 to form a whole, so that heat conduction or heat radiation can be rapidly performed on the lower part 11 of the inner container, and the heat conduction efficiency is improved; when the heating body stops working, the upper part 12 of the inner container forms a closed space 3 with the shell 2, thereby achieving the functions of heat storage and heat preservation.

As shown in fig. 1-4, further, the lower liner portion 11 includes a first liner lower section 111 and a second liner lower section 112 from bottom to top, the first liner lower section 111 is bent inward, and the second liner lower section 112 is bent outward. According to the embodiment, the lower portion 11 of the liner can be shaped in a multi-segment arc shape, so that the internal heat convection of the liner body and the larger heating area of the cooked food are facilitated, and the heating efficiency is improved.

The embodiment also discloses a cooking utensil, which comprises the inner container structure. Optionally, the cooking appliance may be an electric rice cooker or an electric pressure cooker.

The technical means disclosed by the scheme of the utility model is not limited to the technical means disclosed by the embodiment, and also comprises the technical scheme formed by any combination of the technical features. It should be noted that modifications and adaptations to the utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
