The respective components of the cooking appliance 100 will be described in detail below with reference to fig. 1 to 4.

As shown in fig. 1, the pot body 110 of the cooking appliance 100 may have a substantially rounded rectangular parallelepiped shape. In other embodiments of the invention, the pot body 110 can also be in any other suitable shape, such as a generally cylindrical shape. As shown in fig. 2, the pot body 110 has a substantially cylindrical inner pot receiving portion 111, and the substantially cylindrical inner pot 112 can be freely put into and taken out of the inner pot receiving portion 111 to facilitate cleaning of the inner pot 112. The shapes of the inner pot receiving part 111 and the inner pot 112 may be changed as needed. The inner pot 112 may be used to contain food materials to be cooked (e.g., rice, meat, bones, potatoes, etc.) to cook edible foods, such as rice, porridge, soup, etc. The pot body 110 may be provided therein with a heating means 160 for heating the inner pot 112. In this embodiment, the heating device 160 may be located at the bottom of the inner pan 112. In other embodiments of the invention, the heating device 160 may also be located around the side of the inner pan 112.

The lid 120 is openably and closably provided on the pot body 110. Specifically, in the present embodiment, the lid body 120 is pivotably provided above the pot body 110 between the maximum open position and the closed position by means of, for example, a hinge. When the cover 120 is in the closed position, the cover 120 covers the pot body 110, and a cooking space 150 can be formed between the cover 120 and the inner pot 112 of the pot body 110. Alternatively, the cover 120 may be provided with a cover steam outlet (not shown) for discharging high-temperature steam generated in the cooking space 150 during cooking.

The face cover 130 is provided on the cover body 120. Specifically, in the present embodiment, as shown in fig. 3 and 4, the face cover 130 may include a base member 131 and a film member 132 supported on the base member 131. The base member 131 and the membrane member 132 may be made of any suitable material. For example, in the present embodiment, the base member 131 may be made of acrylonitrile-styrene-butadiene copolymer, and the film member may be made of polyester resin (PET). The acrylonitrile-styrene-butadiene copolymer and the polyester resin have good binding force, and the overall strength of the face cover 130 can be improved. The base member 131 and the membrane member 132 are provided thereon with a base member vapor outlet 133 and a membrane member vapor outlet 134, respectively, correspondingly. The base member vapor outlet 133 and the membrane member vapor outlet 134 can be any suitable shape, such as circular, oval, rectangular, and the like. When the face cover 130 is mounted to the cover body 120, the base member steam outlet 133 and the membrane member steam outlet 134 are in fluid communication with the cover body steam outlet to discharge high-temperature steam generated in the cooking space 150 during cooking.

Specifically, the attachment plate 140 may be integrally formed with the film member 132 of the face cover 130 by injection molding and then integrally formed with the base member 131 of the face cover 130 by injection molding. Alternatively, the base member 131 of the face cover 130 may be formed integrally with the film member 132 of the face cover 130 by injection molding, and then integrally formed with the attachment plate 140 by injection molding. The attachment plate 140 is connected to the face cover 130 by the secondary injection molding, the process is simple, and the overall strength is improved.

Second embodiment

Fig. 5 to 8 show schematic views of a cooking appliance 200 according to a second embodiment of the present invention. The cooking appliance 200 will be explained with reference to fig. 5 to 8. The cooking appliance 200 is substantially the same as the cooking appliance 100 of the first embodiment, except that the attachment plate 240 is provided on the inner side surface of the face cover 230. Therefore, for the purpose of simplification, the present embodiment will omit the same portions as the first embodiment.

As shown in fig. 5 to 8, the cooking appliance 200 may mainly include a pot body 210, a lid body 220, a face cover 230, and an attachment plate 240.

The lid 220 of the cooking utensil 200 is openably and closably provided on the pot body 210. When the cover 220 is covered on the pot body 210, a cooking space 250 can be formed between the cover 220 and the inner pot of the pot body 210. Optionally, in the present embodiment, a cover steam outlet (not shown) may be provided on the cover 220. The face cover 230 is provided on the cover body 220. Specifically, in the present embodiment, as shown in fig. 7 and 8, the face cover 230 may include a base member 231 and a film member 232 supported on the base member 231. The base member 231 and the membrane member 232 may be made of any suitable material. For example, in the present embodiment, the base member 231 may be made of acrylonitrile-styrene-butadiene copolymer, and the film member 232 may be made of polyester resin. The base member 231 and the film member 232 are provided with a base member vapor outlet 233 and a film member vapor outlet 234, respectively, correspondingly. The base member vapor outlet 233 and the film member vapor outlet 234 together constitute a face cover vapor outlet.

The attachment plate 240 is attached around the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234) of the face cover 230. The attachment plate 270 may suppress deformation of the face cover 230 due to high temperature. Preferably, the attachment plate 240 may be made of a high temperature resistant material, which is attached to the face cover 230 in a non-destructive and non-detachable manner to more effectively suppress deformation of the face cover 230 due to high temperature. Preferably, the thermal deformation temperature of the material constituting the attachment plate 240 is higher than that of the material constituting the face cover 230, so that the ability of the face cover 230 to withstand high temperature is improved, and the deformation of the face cover 230 due to high temperature can be effectively suppressed.

Unlike the first embodiment, in the present embodiment, the attachment plate 240 may be disposed at an inner side surface of the face cover 230 so as not to affect the external appearance of the cooking appliance 200, and the attachment plate 240 may not necessarily be made of a transparent or translucent material, expanding the selection range of the attachment plate 240. Preferably, the attachment plate 240 may be made of plastic (e.g., polycarbonate, PC) or a metal material (e.g., copper, iron, etc.), reducing material costs.

The attachment plate 240 may be disposed at an inner side of the face cover 230 and cover the entirety of the face cover 230. The attachment plate 240 has the same shape and size as the face cover 230. Alternatively, in the present embodiment, the attachment plate 240 may be disposed at an inner side surface of the face cover 230 and cover only a portion of the face cover 230. The size of the attachment plate 240 is smaller than that of the face cover 230. Specifically, in the present embodiment, the attachment plate 240 may be provided with an attachment plate steam outlet 241 corresponding to the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234) on the face cover 230, the attachment plate 240 being provided around the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234) and the attachment plate steam outlet 241 thereon corresponding to the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234). Generally, the temperature at the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234) is high, and therefore, the face cover 230 is most easily deformed at the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234) by the high temperature. However, in the present embodiment, providing the attachment plate 240 at the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234) can effectively suppress deformation of the face cover 230 at the face cover steam outlet (including the base member steam outlet 233 and the membrane member steam outlet 234).

The attachment plate 240 may be attached to the face cover 230 by any suitable means. In the present embodiment, the attachment plate 240 may be coupled to the face cover 230 by over-molding. Specifically, the film member 232 of the face cover 230 may be placed in a front mold of the injection mold of the base member 231, the attachment plate 240 may be placed in a rear mold of the injection mold of the base member 231, and then the injection base member 231 may be clamped to integrate the three of the base member 231, the film member 232, and the attachment plate 240. Preferably, one or more through holes 242 may be provided on the attachment plate 240. A portion of the face cover 230 penetrates into one or more through-holes 242 of the attachment plate 240 during the injection molding process to improve the coupling force therebetween. Specifically, in the present embodiment, a portion of the base member 231 of the face cover 230 penetrates into the one or more through holes 242 of the attachment plate 240 during the injection molding process. Further preferably, in the present embodiment, a chamfered portion 243 is provided below the through hole 242 of the attachment plate 240. As shown in fig. 8, the diameter of the chamfered portion 243 is larger than the diameter of the through hole 242. Therefore, in the secondary injection molding process, the surface cover 230 and the attachment plate 240 are connected in an i shape at the through hole 242, so that the bonding force between the surface cover 230 and the attachment plate 240 is further improved, and the overall strength is improved.
