In addition, examples of various specific processes and materials are provided herein, but one of ordinary skill in the art may recognize the application of other processes and/or the use of other materials.

The application is described below with reference to specific embodiments in conjunction with the following drawings:

the embodiment of the application provides a gas device and gas-cooker can solve the gas concentration that is close to the air inlet in the outer gas mixing chamber great at least to a certain extent, and the gas concentration of keeping away from the air inlet is less for outer ring fire is unstable, technical problem that combustion efficiency is low.

Example one

The present application provides a gas device 100, as shown in fig. 1 and fig. 2, which is a schematic perspective view of the gas device 100 from two different viewing angles. The gas device 100 is embodied as a part of a gas range for re-mixing supplied gas with air to improve combustion efficiency.

Referring to fig. 3 and 4, fig. 3 and 4 are exploded views of gas device 100 from two different perspectives. The gas device 100 comprises a gas mixing component 10 and a gas mixing ring 20.

Referring to fig. 7, 8 and 9, the gas mixing assembly 10 is provided with an annular gas mixing chamber 11, a mixed gas outlet 13 and an outer ring gas inlet channel 14. Wherein, the mixed gas outlet 13 and the outer ring gas inlet channel 14 are communicated with the annular mixed gas cavity 11. Specifically, when the gas combustion apparatus 100 has an inner ring fire and an outer ring fire, the annular gas mixing chamber 11 is specifically an outer ring gas mixing chamber, and provides a mixed gas for generating the outer ring fire. Specifically, the mixed gas outlet port includes mixed gas outlet ports 12 and 13.

The number of outer ring inlet channel 14 is a plurality of, and a plurality of outer ring inlet channel 14's export all communicates with annular gas mixing chamber 11, and a plurality of outer ring inlet channel 14's export interval sets up in annular gas mixing chamber 11. In addition, the outer ring intake passage 14 is inclined.

Although the number of the outer ring air inlet channels 14 is multiple, in the use process, it is found that in the annular air mixing cavity 11, the gas concentration at the outlet position of the outer ring air inlet channel 14 is far greater than that at the position where the outlet of the outer ring air inlet channel 14 is not arranged, that is, the gas concentration in the annular air mixing cavity 11 is seriously uneven, so that the mixed gas discharged from the mixed gas outlet 12 and 13 is also uneven, the generated outer ring fire is unstable, and the combustion efficiency is low.

Based on this, the air mixing ring 20 is added to the air mixing assembly 10, and the air mixing ring 20 is fixed in the annular air mixing cavity 11 of the air mixing assembly 10 to divide the air mixing cavity 11 into an upper cavity 111 and a lower cavity 112. The air mixing ring 20 is provided with a plurality of through holes 21. The plurality of through holes 21 can communicate the upper chamber 111 and the lower chamber 112 of the gas mixing chamber 11, so that the gas in the lower chamber 112 can enter the upper chamber 111 from the through holes 21.

The lower chamber 112 communicates with the outer ring air intake passage 14, and the outer ring air intake passage 14 gas enters the lower chamber 112 through the outlet of the outer ring air intake passage 14. The upper chamber 111 communicates with the mixed gas outlet 13. After entering the upper chamber 111 from the through hole 21, the gas in the lower chamber 112 is discharged from the mixed gas outlet 13 for combustion, so that the gas can be buffered and decelerated, and the uniformity of gas dispersion is improved.

In order to enable the gas in the lower cavity to enter the upper cavity more uniformly, in some embodiments, the through holes 21 are spaced apart from each other on the gas mixing ring 20, and are spaced apart from each other uniformly, and are formed in a single row to form a ring shape to match the shape of the annular gas mixing cavity 11, in other embodiments, the through holes 21 may not be spaced apart from each other uniformly, and may be formed in multiple rows as long as the gas in the lower cavity 112 can enter the upper cavity 111 through different positions of the gas mixing ring 20. The plurality of through holes 21 are arranged on the gas mixing ring 20 at equal intervals, so that gas in the lower cavity can enter the upper cavity more uniformly at a uniform speed. Specifically, in the present embodiment, the center axes of the plurality of through holes 21 are parallel to the center axis of the annular air mixing chamber 11.

In the specific embodiment, the sum of the areas of all the through holes 21 of the gas mixing ring 20 is larger than the sum of the areas of all the mixed gas outlets, so that sufficient gas can be provided during combustion, and the use by a user is convenient.

In order to make other mixing uniformity higher, an included angle between the central axis of the outer ring air inlet channel 14 and the central axis M of the through hole 21 is set to be 125-145 degrees. The gas discharged from the outlet of the outer ring gas inlet channel 14 enters the lower cavity 112, and because an included angle b of 125-145 degrees is formed between the central axis of the ring gas inlet channel 14 and the central axis M of the through hole 21, the gas can impact the side wall of the lower cavity 112 or the gas mixing cavity 20 after entering the lower cavity 112, so that the gas can be mixed, dispersed and decelerated, and the uniformity of the gas is improved.

Through arranging the through holes 21 on the gas mixing ring 20 at intervals, the fuel gas in the outer ring air inlet channel 14 enters the lower cavity 112 of the gas mixing cavity 11 through the outlet of the outer ring air inlet channel 14, due to the fact that the gas mixing ring 20 is arranged, and the included angle between the central axis of the outer ring air inlet channel 14 and the central axis M of the through hole 21 is 125-145 degrees, the fuel gas cannot immediately enter the upper cavity 111 after entering the lower cavity 112, most of the fuel gas can be diffused, moved and decelerated in the lower cavity 112 under the blocking of the gas mixing ring 20, the uniformity of the gas in the whole lower cavity 112 is greatly improved, then the fuel gas enters the upper cavity 111 through the through holes 21, and the fuel gas entering the upper cavity 111 is discharged from the mixed gas outlets 12 and 13 to be combusted.

By arranging the air mixing ring 20 in the air mixing cavity 11 of the air mixing assembly 10 and setting the included angle between the central axis of the outer ring air inlet channel 14 and the central axis of the through hole 21 to be 125-145 degrees, after the fuel gas enters the lower cavity 112, the gas will diffuse, move and decelerate in the lower cavity 112 under the blocking of the gas mixing ring 20, the uniformity of gas dispersion in the whole lower cavity 112 is greatly improved, the condition that the gas concentration at the outlet position of the outer ring gas inlet channel 14 is far higher than that at the position without the outlet of the outer ring gas inlet channel 14 can be avoided, and the outer ring fire formed when the mixed gas is combusted after being discharged from the gas outlet 13 is stabilized, the combustion efficiency is higher, the problem that the concentration of the fuel gas close to the air inlet in the outer gas mixing cavity is higher can be solved at least to a certain extent, and the gas concentration far away from the gas inlet is small, so that the outer ring fire is unstable, and the combustion efficiency is low.

Specifically, the distance between the inlet and outlet of each outer ring intake passage 14 and the shaft axis N is different, and the distance between the inlet of each outer ring intake passage 14 and the shaft axis N is smaller than the distance between the outlet of the outer ring intake passage 14 and the shaft axis N. In addition, the distances between the inlets of the outer ring intake passages 14 and the shaft axis N may be set to be the same or different, and the distances between the outlets of the outer ring intake passages 14 and the shaft axis N may be set to be the same or different. In the present embodiment, the distances between the inlets of the plurality of outer ring intake passages 14 and the shaft axis N are set to be the same, and the distances between the outlets of the plurality of outer ring intake passages 14 and the shaft axis N are also set to be the same.

The distance between the inlet of each outer ring air inlet channel 14 and the axis N is smaller than the distance between the outlet of the outer ring air inlet channel 14 and the axis N, so that the size of the whole gas device can be reduced, and the manufacturing cost and the occupied space are reduced.

Further, the axis L of each outer ring intake passage 14 of the plurality of outer ring intake passages 14 intersects the axis N of the annular air mixing chamber 11 at the same point. The axial lines L of the outer ring air inlet channels 14 are arranged to intersect with the axial line N of the annular air mixing cavity 11 at the same point, so that the size of the whole gas device can be further reduced, and the manufacturing cost and the occupied space are reduced.
