Claims (5)

A pot with a cooking space, A heating section for heating the aforementioned pot, A lid having an inner lid for sealing the cooking space, A pressure reducing valve is provided in the inner lid and is movable between a sealing position that seals the cooking space and an open position that opens to atmospheric pressure, A valve drive unit is provided on the lid and moves the position of the pressure reducing valve to be variable, A lid locking member is provided on the lid and is movable between a locked position that restricts the opening of the lid and an unlocked position that enables the opening of the lid. The lid is provided with a lid lock drive unit having an operating member for operating the lid locking member by manual operation by the user, The valve drive unit has a first engaging portion, and the lid lock drive unit has a second engaging portion that engages with the first engaging portion. The valve drive unit and the lid lock drive unit each rotate, The rotation shaft of the valve drive unit and the rotation shaft of the lid locking member are coaxial. The lid is provided with a handle that is rotated as the operating member, and a shaft member that extends in the thickness direction of the lid as the axis of rotation of the handle. A cooking appliance in which a through hole is formed in the rotating center of the valve drive unit through which the shaft member is inserted .
The heating appliance according to claim 1, wherein the first engaging portion is either an elongated hole or a pin, and the second engaging portion is the other.
The lid lock drive unit has an arm member that extends laterally inside the lid to connect the operating member and the lid lock member, The heating appliance according to claim 2, wherein the second engaging portion is a pin provided in the arm material, and the first engaging portion is an elongated hole through which the pin is inserted.
The heating appliance according to any one of claims 1 to 3 , wherein the operating member comprises a handle that is rotated about a rotation axis extending along the thickness direction of the lid.
The inner lid further comprises a movable member that is positioned in a first position when the pressure in the cooking space is above a predetermined pressure, and in a second position when the pressure is below the predetermined pressure. The heating appliance according to any one of claims 1 to 3, wherein the movable member selectively engages with the lid locking member such that it restricts the movement of the lid locking member in the first position and does not restrict the movement of the lid locking member in the second position.

Description

This disclosure relates to a heating appliance. Conventionally, cooking appliances that heat food and other prepared items in a pot have been known (see, for example, Patent Document 1). The heating appliance described in Patent Document 1 has a mechanism that automatically operates a pressure reducing valve (pressure release valve) for controlling the pressure inside the pot. When predetermined conditions are met, such as during cooking or at the end of cooking, the pressure reducing valve is operated to release the pressure inside the pot to atmospheric pressure.
