Illustratively, the number of fire holes 4A on the outer ring fire cover 41 is plural, and the number of fire holes 4A on the inner ring fire cover 42 is plural.

For example, referring to fig. 4 and 5, an outer ring fire cover 41 is provided on the distributor 3 and forms an outer ring gas mixing chamber 3A with the distributor 3, and the gas ejected from the outer ring nozzle 241 enters the outer ring ejecting pipe 311 after ejecting primary air, and then the gas and the air are fully mixed in the outer ring gas mixing chamber 3A and ejected from the fire hole 4A on the outer ring fire cover 41 and combusted. The inner ring fire cover 42 is arranged on the distributor 3 in a covering manner, and forms an inner ring gas mixing cavity 3B with the distributor 3, gas ejected by the inner ring nozzle 242 enters the inner ring ejecting pipe 312 after ejecting primary air, and then the gas and the air are fully mixed in the inner ring gas mixing cavity 3B, and then ejected from the fire hole 4A on the inner ring fire cover 42 and burnt.

Illustratively, the number of gas nozzle columns 22 is two, as are the number of gas connection ports 23. The first gas nozzle column 22 and the first gas connection port 23 are arranged corresponding to the outer ring nozzle 241; the second gas nozzle column 22 and the second gas connection port 23 are provided corresponding to the inner ring nozzle 242.

In one implementation, the inner ring ejector tube is disposed generally vertically, so that the inner ring ejector tube is disposed near the center of the upper air intake gas stove, and the inner ring nozzle is also disposed near the center of the upper air intake gas stove. The outer ring injection pipe is generally horizontally arranged, the outer ring nozzle is generally arranged at the edge position of the complete upper air inlet gas stove, pipelines from the gas connection port to the inner ring nozzle and the outer ring nozzle are required to be respectively designed, and longer pipelines are required to be arranged between the gas inlet of the upper air inlet gas stove and the inner ring nozzle, so that the internal structure of the upper air inlet gas stove is complex.

Based on this, in some embodiments of the present disclosure, as shown in fig. 11, the gas nozzle column 22, the gas connection port 23, and the nozzle 24 are located at the same side of the fixing plate 21 in the horizontal direction.

It will be appreciated that the gas nozzle post 22, gas connection port 23 and nozzle 24 are all located on the side of the gas conduit adjacent the user.

As shown in fig. 9, by the above arrangement, the distance between the gas connection port 23 and the nozzle 24 can be made short, and accordingly, the gas inlet passage 22A in the gas nozzle column 22 can be made short, so that it is possible to avoid providing a long connection pipe between the gas connection port 23 and the nozzle 24, and thus it is possible to simplify the internal structure of the upper air-intake gas cooker 100 and to reduce the volume of the upper air-intake gas cooker 100 to some extent. The above arrangement can also reduce the gas transmission resistance and simplify the production and processing technology of the base 2.

Thus, the upper air intake gas cooker 100 provided in the embodiment of the disclosure comprises a cooking bench 1, a base 2, a distributor 3 and a fire cover 4, wherein a fixing plate 21 in the base 2 is fixed on a bottom shell of the cooking bench through a bracket 211, and by forming an air intake channel 22A in a gas nozzle column 22 and communicating a gas connection port 23 and a nozzle 24 with two ends of the air intake channel 22A respectively, external gas can be conveyed to the nozzle 24 through the gas connection port 23. By arranging the distributor 3 above the fixing plate 21 and arranging the fire cover 4 on the distributor 3, the complete upper air intake combustion of the upper air intake gas stove 100 can be realized. By locating the gas nozzle column 22, the gas connection port 23 and the nozzle 24 on the same side of the fixing plate 21 in the horizontal direction, the distance between the gas connection port 23 and the nozzle 24 can be made shorter, and accordingly, the gas inlet passage 22A in the gas nozzle column 22 can be provided shorter, so that the length of the pipe between the gas connection port 23 and the nozzle 24 can be reduced, whereby the internal structure of the upper air-intake gas cooker 100 can be simplified, and the volume of the upper air-intake gas cooker 100 can be reduced to some extent. The above arrangement can also reduce the gas transmission resistance and simplify the production and processing technology of the base 2.

In some examples, as shown in fig. 5 and 11, the outer ring fire cover 41 forms an outer ring gas delivery chamber 3A with the distributor 3, the outer ring gas delivery chamber 3A communicating with the outer ring injector tube 311.

Through the arrangement, air can be transmitted to the inner ring fire cover 42 through the second ventilation holes 3C and the first ventilation holes 42A, so that air can be provided for gas combustion on the inner ring fire cover 42, and the combustion is more sufficient. In addition, the second ventilation holes 3C and the first ventilation holes 42A may reserve an upgrade space for the temperature sensor, and when the dry burning prevention function needs to be added to the upper air intake gas stove 100, the temperature sensor may be directly installed in the second ventilation holes 3C and the first ventilation holes 42A, so that the universality of the upper air intake gas stove 100 is increased.

The gas entering through the inner ring gas connection port 232 passes through the inner ring gas inlet passage of the inner ring gas nozzle column 222 and is ejected from the inner ring nozzle 242 to the inner ring ejector 312.

In this way, the gas can be provided for the upper air inlet gas stove 100 through the outer ring gas connection port 231 and the inner ring gas connection port 232 at the same time, so that the heating speed of the upper air inlet gas stove 100 can be improved.

By providing the weight reducing holes 21B, the material cost of the fixing plate 21 can be reduced, and the weight of the fixing plate 21 can be reduced.

In some examples, as shown in fig. 13, the distributor 3 further includes a decorative cover plate 33 disposed above the outer ring injection pipe 311 and the inner ring injection pipe 312, so that when the soup produced during cooking is sprinkled on the decorative cover plate 33, the cleaning by a user can be facilitated, and meanwhile, the overall appearance of the upper air intake gas cooker 100 can be simplified and attractive.

On the other hand, the embodiment of the present disclosure also provides an upper air intake gas cooker 100 in which the gas nozzle column 22 and the nozzle 24 are both disposed close to the gas connection port 23 in the horizontal direction.

By the above arrangement, the distance between the gas connection port 23 and the nozzle 24 can be made shorter, and accordingly, the gas inlet passage 22A in the gas nozzle column 22 can be made shorter, so that a longer connection pipe can be avoided from being provided between the gas connection port 23 and the nozzle 24, thereby simplifying the internal structure of the upper air inlet gas cooker 100 and reducing the volume of the upper air inlet gas cooker 100 to a certain extent. The above arrangement can also reduce the gas transmission resistance and simplify the production and processing technology of the base 2.

The foregoing is merely a specific embodiment of the disclosure, but the protection scope of the disclosure is not limited thereto, and any person skilled in the art who is skilled in the art will recognize that changes or substitutions are within the technical scope of the disclosure. Therefore, the protection scope of the present disclosure shall be subject to the protection scope of the claims.
