Document Type and Number:
WIPO Patent Application WO/2019/085214
Kind Code:
A cooking vessel control device for a stir fry machine comprises a driving device (200), a fixed-point working position changing device (100), a controller, and a rotary shaft (300) for connection of a cooking vessel (500) of a stir fry machine. The fixed-point working position changing device (100) comprises an emission plate (1), a reception plate (2), and a rotary blocking plate (3). The rotary blocking plate (3) is connected to the rotary shaft (300). 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 ensuring that the controller controls an output shaft of the driving device (200) to stop rotating, and accordingly enabling the cooking vessel to stop precisely at the corresponding fixed-point working position.
