The sealing plug 35 is used to seal the vent hole 37, and can prevent water from entering the hollow cavity 36 from the vent hole 37 during the process of cleaning the heater tray assembly 14, which may cause safety problems. The sealing plug 35 comprises a plug body 38 and a lip 39, the lip 39 extending from the side of the plug body 38 away from the hollow cavity 36 and being disposed obliquely to the plug body 38. Optionally, the angle between the generatrix of the lip 39 and the central axis of the sealing plug 35 ranges between 30 and 45 degrees. This improves the sealing performance of the sealing plug 35, so that the hotplate assembly 14 is better sealed. A lip 39 extends from the side of the plug body 38 away from the hollow cavity 36 to facilitate the installation of the sealing plug 35 into the vent hole 37. Meanwhile, the lip 39 is obliquely arranged relative to the plug body 38, and the lip 39 has elasticity, so that the interference magnitude between the sealing plug 35 and the vent hole 37 is improved, the fixing effect of the sealing plug 35 is better, and the sealing performance is better. And when the vent hole 37 takes place the deformation, lip 39 can kick-back, so make lip 39 can be supported and connected in the inner wall of vent hole 37 all the time, guaranteed the sealing performance of heater tray subassembly 14.

In some embodiments, the plug body 38 is an interference fit with the vent hole 37 such that the plug body 38 can be retained within the vent hole 37. The plug body 38 includes a first plug body portion 40 and a second plug body portion 41, and the first plug body portion 40 and the second plug body portion 41 are arranged along the extending direction of the vent hole 37. The width of the first stopper portion 40 is smaller than the width of the second stopper portion 41 in the aperture direction of the vent hole 37. It will be appreciated that when the heater tray assembly 14 is applied to the food processor 10, the width of the first stopper portion 40 is smaller than the width of the second stopper portion 41 in the horizontal direction. The lip 39 extends from the side of the first stopper portion 40 away from the hollow cavity 36 and is disposed at an angle relative to the first stopper portion 40. The lip 39 may be disposed on the first stopper portion 40. Thus, while ensuring the sealing performance, the interference between the sealing plug 35 and the vent hole 37 is prevented from being too large, and the reaction force of the inner wall of the vent hole 37 acting on the sealing plug 35 is prevented from being too large, so that the sealing plug 35 is prevented from being separated from the vent hole 37.
