Abstract
Description
[Technical field]
[0001] The invention relates to a commercial stove control system and a stove using the stove system. [Background technology]
[0002] In commercial (restaurants and other places) stoves, high-power burners are required because of the large combustion power required. Commercial burners usually consume a large amount of gas when in use and may go out during use. Therefore, a long-lasting flame is usually set when in use. The long-lasting flame will remain burning when the main burner is burning or the fire is temporarily turned off. Currently, the most common commercial burners on the market are patent number 202210977169.7, named a wind and air linkage adjustment device for commercial gas stoves, which is designed with only one long-lasting flame gas. Since the long-lasting flame is used to ignite the main burner, the long-lasting flame also has a certain power. However, after the main burner is ignited, in order to prevent the flame from going out, the long-lasting flame does not actually need such a large power to maintain the fire. The long-lasting flame works at a relatively large power for a long time, which wastes a lot of gas. [Summary of the invention]

[0026] The present invention will be further described below in conjunction with the accompanying drawings:
[0027] Embodiment 1, as Figures 1 to 7As shown, a control system for a commercial stove includes a main burner 1, an ignition burner 2 for igniting the main burner 1, and an air inlet pipe 3. An ignition needle and an induction needle are provided on one side of the ignition burner 2. The flame of the ignition burner 2 ignites and maintains the flame of the main burner 1. A main solenoid valve 4 for controlling the on-off of the gas in the air inlet pipe 3 is provided at the air outlet end of the air inlet pipe 3. The air inlet pipe 3 is connected to the gas. The main solenoid valve 4 is provided with three air outlet ends and is respectively connected to the first solenoid valve 5, the second solenoid valve 6 and the long-fire gas pipe 7 for supplying gas to the ignition burner 2. The main air outlet end of the main solenoid valve 4 has three branch air outlet channels connected to the main air outlet end. The first solenoid valve 5 and the second solenoid valve 6 are respectively in two of the branch air outlet channels to control the on-off of the gas in the branch air outlet channels. The remaining branch air outlet channel is connected through the long-fire gas pipe 7. The gas outlet end of the first solenoid valve 5 supplies gas to the main burner 1 through the main gas supply pipe 51. When the first solenoid valve 5 opens the main gas supply pipe 5, the gas enters the main burner 1. The second solenoid valve 6 supplies gas to the ignition burner 2 through the enhanced fire gas pipe 61 . When the second solenoid valve 6 opens the enhanced fire gas pipe 61 , the gas enters the ignition burner 2 . When the main burner 1 (main fire) is needed to work, operate the control switch (for example, press the switch twice), the ignition needle ignition starts first, it can be set after about 1s, the main solenoid valve 4 opens, the ignition burner 2 is connected to the long-burning flame gas 7 gas, the ignition needle ignites, and the ignition burner 2 is in a long-burning flame state. At this time, the inlet gas is supplied to the ignition burner 2. It can be set after about 1s, the second solenoid valve 6 automatically opens, and the enhanced fire gas pipe 61 gas enters the ignition burner 2. At this time, two gas supplies are supplied to the ignition burner 2, the ignition burner 2 has sufficient power to ignite, and the flame of the ignition burner 2 is enhanced. It can be set after about 2s, the first solenoid valve 5 automatically opens, the main burner 1 is connected to the main gas supply pipe 51 gas and ignites and burns under the enhanced flame of the ignition burner 2. After the ignition is completed (it can be set after 5s), the second solenoid valve 6 automatically closes, and the ignition burner 2 maintains a long-burning flame. At this time, the inlet gas is supplied to the ignition burner 2. When the control button is operated to close the main burner 1 (for example, pressing the switch once), the second solenoid valve 6 is closed, the first solenoid valve 5 remains open, and the ignition burner 2 maintains a long flame. At this time, when the control button is operated again (pressing the switch once again) to open the main burner 1, the second solenoid valve 6 is opened first, and then the first solenoid valve 5 is automatically opened (it can be set after about 2s), and the main burner 1 ignites under the enhanced flame of the ignition burner 2. After the ignition is completed (it can be set after about 5s), the second solenoid valve 6 is automatically closed; when shutting down, the control button is operated (for example, pressing the switch for 2s), the main solenoid valve 4 and the first solenoid valve 5 are closed, the second solenoid valve 6 remains closed, and the flames of the main burner 1 and the ignition burner 2 are both extinguished.If an emergency occurs and the long-lasting flame of the ignition burner 2 is not ignited or is extinguished, the sensing needle does not detect the flame signal of the ignition burner 2 or the signal disappears and controls the main solenoid valve 4 to disconnect. The long-lasting flame is not ignited and there is no flame signal at a low temperature. The long-lasting flame is extinguished, the temperature gradually decreases, and the flame signal disappears. The main solenoid valve 4 and other solenoid valves in the open state will be automatically controlled to disconnect to ensure safety.
[0028] For the convenience of control, the air intake pipe 3 is provided with a first manual switch 31 on the front side of the main solenoid valve 4, which can control the on and off of the gas in the air intake pipe 3.

Specifically, the main gas supply pipe 51 is divided into a central fire gas channel 53, a first gas channel 54 and a second gas channel 55 that are connected. The venturi tube 14 includes a central tube 15, a first fire tube 16 and a second fire tube 17.
