[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] like Figure 1 As shown, a multi-burner gas stove with manual and timed operation includes a stove shell 1, several burners 2, a gas valve (not shown in the figure), a main control board and a remote control 3 installed inside the stove shell 1. In this embodiment, three burners are provided. When in use, four or more burners can be set.

[0032] Burner 2 includes thermocouple 21 and ignition needle 22.

[0033] The gas valve includes a solenoid valve, which has two coils with opposite winding directions;
