The cover 10 is an integrally formed structure for wrapping water entering through a gap between the knob and the face cover 10, and at the same time, a through hole 31 is formed on the side of the waterproof cover 30, as indicated by a straight arrow in FIG. The water entering through the knob enters the base 40 with the through hole 31, and then is discharged from the drain hole 42 of the base 40, and at the same time, a water retaining wall 33 is extended on the waterproof cover 30 for preventing water splashing through the through hole 31 to the knob The plate 50 is provided with a water retaining rib 43 on the base 40, and the portion of the knob plate 50 on the base 40 is separated from the portion of the coil disk, the fan and the electric control board on the base 40, wherein the base 40 is the lowest. The point portion is outside the projection of the knob plate 50 projected onto the base 40. The drain hole 42 is located at the lowest point of the base 40, and the base 40 has a convex portion designed, and the lowest point of the convex portion is outside the projection range of the knob plate 50. The knob plate 50 is located at the convex portion, and the convex portion defines a flow guiding wall 41 for downwardly extending to the drain hole 42 to guide the water to the drain of the lowest point of the base 40. Holes 42 are provided to facilitate draining water within the base 40.

In summary, the kitchen appliance provided by the present invention has a cover for mounting a knob and a waterproof cover for receiving water leaking from a knob mounting portion as an integral structure, which is divided into a cover and a waterproof cover. In the solution of the body structure, the matching precision between the waterproof cover and the cover can be effectively ensured, and the waterproof cover and the surface are prevented from being excessively caused by the processing error of the waterproof cover or the cover or the assembly error of the waterproof cover and the cover is too large. The problem of water leakage in the joint of the cover ensures that the water retaining function of the waterproof cover is reliable in the product, the waterproofness of the knob portion of the kitchen appliance is improved, the product quality is improved, and the waterproof cover and the cover are designed as a one-piece structure, thereby saving The step of assembling the waterproof cover and the cover makes it possible to reduce the time and cost of product assembly.
