The pot body 110 is substantially in a rounded rectangular parallelepiped shape, and has a cylindrical-shaped receiving portion. The inner pot may be configured to be freely put into or taken out of the receiving part to facilitate cleaning of the inner pot, or configured to be fixed in the pot body 110 so as not to be taken out of the pot body 110. The inner pot is generally made of a metal material for containing a material to be heated, such as rice, soup, etc. In addition, a heating device and a control device are further disposed in the pot body 110, the heating device may be located below the inner pot to heat food in the inner pot, and a user can control the cooking operation of the cooking appliance 100 through the control device. As shown in fig. 1, a lid opening button 131 is further provided on the pot body, and the cooking appliance further includes a lid locking structure (not shown), and the lid opening button 131 can be engaged with the lid locking structure, so that when the lid opening button 131 is pressed, the lid locking structure can be unlocked, so that the user can open the lid 120.

With continued reference to fig. 1, the cover body 120 mainly includes a face cover 121 and an operation panel 129 partially covering an upper side of the face cover 121. Specifically, the operation panel 129 is located at the topmost end of the cover 120, so that a user can operate the cooking appliance 100 through the operation panel 129. The operation panel 129 may be made of a transparent resin material. The face cover 121 is integrally formed of a resin material through an injection molding process. In the present invention, the directional terms "upper", "lower", "outer" and "inner" refer to directions determined based on the cooking appliance 100 which is placed upright and the lid 120 is in the closed state, and the directional term "front" refers to a direction of the cooking appliance 100 facing a user with reference to a position where the user uses the cooking appliance 100. As shown in fig. 1, the cover 120 is further provided with a steam valve 132 having one end communicating with the cooking space and the other end communicating with the outside, so that steam in the cooking space can be discharged through the steam valve 132.

As shown in fig. 2 to 5, the top plastic wall 122 and the lateral plastic wall 123 intersecting with the top plastic wall 122 are disposed on the surface cover 121, the top plastic wall 122 extends substantially along the horizontal direction, and the lateral plastic wall 123 is located at the peripheral edge of the top plastic wall 122 and extends substantially along the vertical direction.

As shown in fig. 2 and 3, the top plastic wall 122 has a glue inlet wall 124, the glue inlet wall 124 has a glue inlet portion 124a, and the glue inlet portion 124a may correspond to a glue inlet of the mold. In the process of injection molding of the surface cover, the glue enters through the glue inlet part 124a, passes through the glue inlet wall 124 and flows into other areas to form the whole surface cover. In the illustrated embodiment, the glue inlet wall 124 is provided at the front of the face cover 121, and is located near the center of the face cover 121 in the width direction.

As shown in fig. 2 and 5, the glue inlet wall 124 and the side plastic wall 123 intersect to form an intersection 123b, and the intersection 123b is slightly lower than the topmost end of the side plastic wall 123, so that the side plastic wall 123 forms a step 123a at the intersection 123 b. The step portion 123a can be provided for the operation panel 129 to be clamped therein.

The glue inlet wall 124 has a transition wall 125 disposed adjacent to the side plastic wall 123, at least a bottom side surface 125a of the transition wall 125 being disposed obliquely with respect to a horizontal plane toward the step portion 123 a. That is, in the injection molding process of the face cover 121, when the glue enters the glue inlet wall 124 through the glue inlet portion 124a, the glue passes through the transition wall 125 and then is rushed upward into the step portion 123a along the inclined transition wall 125. As described above, in the conventional surface cover, a dead space is formed at the step portion 123a of the side portion plastic wall 123 during injection molding, and when the inlet glue is filled therein, the inlet glue stops flowing and becomes cold, and when new inlet glue flows therein, a black line is formed therein due to cold and hot combination of the inlet glue. According to the above-mentioned aspect of the face cover 121, by arranging the bottom surface 125a of the transition wall 125 in an inclined manner with respect to the horizontal plane toward the step 123a, the face cover 121 can enable the glue injection to be rapidly and continuously flushed to the step 123a at the top via the inclined portion of the glue inlet wall 124 during the injection molding process, and then spread from the step 123a to fill the whole product. The scheme has the advantages of simple structure, easy realization and lower cost. It is understood that in other embodiments not shown, the top surface of the transition wall 125 may also be provided to be inclined toward the stepped portion 123 a.

In one embodiment, the bottom side surface 125a of the transition wall 125 may be provided as a straight wall, and in other embodiments, the bottom side surface 125a of the transition wall 125 may also be provided as a curved wall, i.e., having an arc surface, as long as the transition wall 125 is entirely inclined toward the step portion 123 a.

Preferably, as shown in fig. 5, the bottom side surface 125a has an inclination angle a of 10 ° to 85 ° with respect to the horizontal plane. For example, the inclination angle a may be set to 20 °, 50 °, 60 °, or the like. Those skilled in the art can specifically set the size of the inclination angle according to the depth of the step portion 123a and the thickness of the wall in the vicinity. In the case where the bottom surface 125a is a curved wall, the inclination angle of the bottom surface 125a with respect to the horizontal plane means an average value of angles between tangents to the bottom surface 125a and the horizontal plane.

Preferably, the thickness of the transition wall 125 is less than the thickness at other portions of the glue inlet wall 124. The scheme can avoid the generation of depressions due to the shrinkage of the surface of the product.

As shown in fig. 3-5, the glue inlet wall 124 is generally fan-shaped in cross-section, i.e., the glue inlet wall 124 has a generally fan-shaped configuration when viewed in plan (as shown in fig. 4). Wherein the corners of the sector have a rounded configuration and face the inside of the face cover 121 and the expanded portion of the sector is directed to the outside of the face cover 121. The glue inlet portion 124a is provided at a corner of the sector. This scheme can play the effect of dispersion into gluey through making into gluey wall 124 structure fan-shaped structure to can accelerate into gluey velocity of flow. In the illustrated embodiment, the top plastic wall 122 is provided with a recess 126, and the glue inlet wall 124 is disposed in the recess 126 and configured as a bottom wall of the recess 126. This scheme can be convenient for install operating panel and can be convenient for advance gluey. Preferably, as shown in fig. 4, the central angle B of the fan shape is 5 ° to 160 °. Illustratively, the central angle B may be set to 30 °, 60 °, 90 °, or the like.

In a preferred embodiment, as shown in FIG. 5, the height d of the step portion 123a is 1.5 to 4.5 mm. Illustratively, the height d of the step 123a may be set to 1.5mm, 2.5mm, 4.5mm, or the like. In this embodiment, the height of the step portion 123a is set within the above range, so that the glue can be more easily pushed into the top of the step portion 123 a.
