Examples
As shown in fig. 1 to 15, in the present embodiment, a gas distribution seat 100 is provided, a gas distribution chamber is provided in the gas distribution seat 100, a fire protection structure is provided on an inner side wall of the gas distribution chamber, the fire protection structure includes a fire protection groove 110 and a first fire protection hole 120, the fire protection groove 110 and the first fire protection hole 120 are both penetrated between the gas distribution chamber and an inner wall surface of the inner side wall of the gas distribution seat 100, an inlet of the fire protection groove 110 and an inlet of the first fire protection hole 120 are both communicated with the gas distribution chamber, and an outlet of the fire protection groove 110 and an outlet of the first fire protection hole 120 are both used for corresponding to a fire protection sensing element; the fire protection groove 110 is communicated with the first fire protection hole 120, and the fire protection groove 110 extends along the axial direction of the gas distribution base 100.
Referring to fig. 11, the axial direction of the gas distributor 100 is also the vertical direction, and the inner side wall of the gas distributor 100 can be understood as the side wall close to the radial center of the gas distributor 100, and the fire protection sensing element is correspondingly arranged on the inner side of the side wall. As shown in fig. 11, 12, 14 and 15, the inner side wall of the gas distributor 100 of the present embodiment is provided with a fire protection groove 110 and a first fire protection hole 120, the fire protection groove 110 and the first fire protection hole 120 can introduce the mixed gas in the gas distributor 100 into outlets of the fire protection groove 110 and a second fire protection hole 130, that is, positions corresponding to the fire protection sensing element, and meanwhile, the fire protection groove 110 has a certain extension length in the vertical direction.
It is understood that the fire protection sensing element of the present embodiment is an element for protecting a combustion flame by sensing a fire protection flame. The fire protection sensing element is generally a thermocouple 500, and when the head of the thermocouple 500 is burned by fire protection flame, the electromotive force of the thermocouple 500 is increased, thereby controlling fire protection.
When the burner using the gas distributing base 100 of the present embodiment is burning, since the fire protection slot 110 and the first fire protection hole 120 are both communicated with the gas distributing chamber, the fire protection flame acting on the fire protection sensing element (e.g. the thermocouple 500) can be formed at the outlets of the fire protection slot 110 and the first fire protection hole 120. Because the fire protection groove 110 extends along the axial direction of the gas distribution base 100, the flame formed by the fire protection groove 110 is a plane flame extending along the axial direction of the gas distribution base 100 (which can be understood as the up-down direction of the gas distribution base 100), the flame formed by the first fire protection hole 120 is a substantially cylindrical flame, the plane flame and the cylindrical flame are combined to form a fire protection flame through the communication between the first fire protection hole 120 and the fire protection groove 110, the deformability of the fire protection flame when the combustion space is changed is enlarged, the capability of adapting the fire protection flame to different pots to protect the fire is further improved, and the flame stability of the burner adopting the inner flame mode when different pots are used is improved.
For example, when a pan is used, the combustion space of the gas is less limited, and the fire-protecting flame formed by the first fire-protecting hole 120 and the fire-protecting groove 110 can act on the fire-protecting sensing element; when using sharp bottom pan or bottom convex circular pan, the combustion space of gas reduces for the pan, and the common fire protection flame that forms of first fire protection hole 120 and fire protection groove 110 changes downwards this moment, and the width grow that stretches of flame to still can act on fire protection sensing element, realize fire protection.
