Pressure cooker with splashing preventing and oily water collecting functions

Abstract

The invention provides a pressure cooker with splashing preventing and oily water collecting functions. The pressure cooker comprises a cooker body, a cooker lid and a cylindrical cover (2). A receiving groove (3) is formed in the lower portion of the cylindrical cover (2); the cylindrical cover (2), an inner ring wall (31) and a groove bottom (32) are integrated to form the receiving groove (3); bottom raised heads (33) are arranged on the lower side of the groove bottom (32), and the cylindrical cover (2) and the receiving groove (3) sleeve the outer periphery of a valve bonnet (11), are supported on the surface of the cooker lid (1) via the bottom raised heads (33) and are in contact connection with the cooker lid (1); the peripheral edge of the upper end of the inner ring wall (31) is lower than the lower edge of a bonnet hole (12). The pressure cooker has the advantages that the pressure cooker has splashing preventing, oily water collecting and noise reducing functions, is safe in use, can bring convenience for cooking utilization and has popularization and application value.

Description

technical field

[0001] The invention relates to a pressure cooker for cooking, in particular to a pressure cooker with functions of preventing splash and collecting oil and water. Background technique

[0002] The cooking pressure cooker (hereinafter referred to as: pressure cooker) that the public uses on the gas range or induction cooker daily, for safety needs, the pot cover of pressure cooker is provided with gravity-type pressure-limiting exhaust valve (hereinafter referred to as: pressure-limiting valve). When the pressure cooker exhausts under pressure limitation, most of the gas is ejected from the four vent holes (hereinafter referred to as: cap holes) on the gravity cap (hereinafter referred to as: valve cap) of the pressure limiting valve, and the following inconveniences are prone to occur: 1. The hot gas mixed with oil, water and fine food particles (hereinafter collectively referred to as: mixed fluid) sprayed out along the horizontal direction is easy to splas...
