Title:
FIXED-POINT WORKING POSITION CHANGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/085213
Kind Code:
A1
Abstract:
A fixed-point working position changing device comprises an emission plate (1), a reception plate (2), and a rotary blocking plate (3). The rotary blocking plate (3) is rotatably provided between the emission plate (1) and the reception plate (2). A light-emitting sensor (41) is provided at the emission plate (1). A light-receiving sensor (42) is provided at the reception plate (2). The light-emitting sensor (41) and the light-receiving sensor (42) are arranged opposite to each other. When the rotary blocking plate (3) rotates to a corresponding fixed-point working position, a light aperture (31) of the rotary blocking plate (3) is positioned opposite to the corresponding light-emitting sensor (41) and light-receiving sensor (42), such that a light path is formed between the light-emitting sensor (41) and the light-receiving sensor (42), thereby preventing a rotary shaft of a cooking vessel connected to the rotary blocking plate (3) from rotating, enabling the cooking vessel to precisely stop at the corresponding fixed-point working position, increasing precision of a change in a working position of a cooking vessel, and enhancing convenience of using a stir fry machine.
