Referring to fig. 1, 2, 3 and 9, the flow guide member 4 provided in the present embodiment may be used in a combustor 10. In the embodiments of the present description, the flow guide 4 is mainly described in detail by taking the application in the burner 10 of the gas cooker as an example, and other usage scenarios can be adaptively replaced by referring to the present application, which is not repeated herein.

The combustor 10 may include: a distributor 1 having a height gap in the height direction from a face plate 6, and a sensor 2 provided in the distributor 1. A transverse gap is formed between the sensor 2 and the distributor 1. The panel 6 is provided with a through portion 61, and the through portion 61 communicates with the height gap and the lateral gap.

As shown in fig. 1, the distributor 1 may comprise a body having a central hole 11 formed in the middle. The body is provided with a fire outlet. The sensor 2 may be inserted into the central hole 11. Furthermore, the position of the sensor 2 can be adapted according to the specific form of the burner 10. For example, when the burner 10 is a double ring fire burner 10, the sensor 2 may be disposed between the inner ring gas groove 13 and the outer ring gas groove 12. In the embodiments of the present description, the sensor 2 is mainly housed in the center hole 11 of the distributor 1, for example, and will be described in detail.

When the burner 10 is burning, the flame is sprayed from the fire outlet of the burner 10, which heats the surrounding air, and a thermodynamic cycle as shown in fig. 1 is formed between the outer wall of the distributor 1 and the central hole 11, which continuously transfers heat to the sensor 2, thereby reducing the reliability of the sensor 2 during use and shortening the service life thereof.

In order to reduce the negative influence of the thermodynamic cycle on the sensor 2, in the present embodiment, the air guide 4 forms a first air flow gap H with the through portion 61 in the height direction and/or forms a second air flow gap L with the through portion 61 in the direction extending along the panel 6. Overall, the above-mentioned air flow gap provides an air flow path for the cold air between the underside of the panel 6 to the bottom wall of the distributor 1. The air flow channel guides at least part of cold air below the panel 6 to the height gap between the bottom wall of the distributor 1 and the panel 6, so that the cold air is mixed into a thermodynamic cycle, the influence of the thermodynamic cycle on the sensor 2 is reduced, namely the temperature of the sensor 2 can be reduced, and the service life and the reliability of the sensor 2 are improved.

The flow guiding part 41 for guiding flow on the upper portion of the flow guiding member 4 may be plate-shaped, or may be an inclined flange formed on the fixing part 42, or may be other regular or irregular shapes.

After this water conservancy diversion spare 4 is set up between this panel 6 and this distributor 1, because this water conservancy diversion spare 4 is less than the clearance of distributor 1 apart from panel 6 apart from the clearance of this panel 6, consequently not only can effectively change the flow direction of panel 6 below cold air, and can accelerate the velocity of flow of cold air, can be promptly with the leading-in thermodynamic cycle of the cold air of panel 6 below with faster velocity of flow, make the hot-air high-efficient mixture in cold air and the thermodynamic cycle, realize the heat exchange, thereby the temperature rise of effective control sensor 2, reduce the influence of combustion environment to sensor 2.

Further, the distance of the deflector 4 from the bottom surface of the distributor 1 in the height direction is smaller than the distance of the deflector 4 from the panel 6, so that most of the cold air below the panel 6 is guided into the thermodynamic cycle. In which a small portion of the cold air possibly flows into the central hole 11, which cold air flowing into the central hole 11 is substantially unable to play a cooling role for the sensor 2, contrary to the direction of the thermodynamic cycle.
