Pressure cooker

Abstract

The invention discloses a pressure cooker which comprises an outer pot, annular supporting pieces, a coil disc, an air duct support and a fan. A turned edge extending inwards is arranged at the lower end of the outer pot. An opening in the bottom of the outer pot is defined by the turned edge. The turned edge is provided with a plurality of elastic pieces. The annular supporting pieces support the elastic pieces and can move in the vertical direction. The coil disc is arranged on the annular supporting pieces and located below the annular supporting pieces. The opening in the bottom is matched with the coil disc. The air duct support is arranged on the outer bottom wall of the outer pot. An outer annular protrusion protruding towards the coil disc is arranged on the upper surface of the air duct support. The width, in the radial direction, of the outer annular protrusion is matched with the width, in the radial direction, of the coil disc. An air duct with an air inlet and an air outlet is defined by the outer annular protrusion, the upper surface of the air duct support, the lower surface of the coil disc and the outer pot together. The fan is arranged at the air outlet. According to the pressure cooker, the coil disc is good in cooling effect, the outer pot is high in structural strength, and the pressure cooker is stably supported by an inner pot.

Description

technical field [0001] The invention relates to the field of household appliances, in particular to a pressure cooker. Background technique [0002] In the related technology of electromagnetic heating electric pressure cooker, the inner pot can move up and down relative to the outer pot, the coil plate is located in the outer pot, and the inner pot is supported on the outer pot through an elastic structure. When the pressure cooker is working, the coil plate cannot bear pressure, and the inner pot needs Under a lot of pressure, the coil plate emits a lot of heat at the same time, the fan is installed under the coil plate, the blowing of the fan cannot pass over the entire coil plate, the cooling effect on the coil plate is poor, and there is room for improvement, so the heat dissipation structure of the coil plate and the inner pot The supporting structure and the structural strength of the outer pot all need to be further improved.
