detailed description

The invention will now be described in further detail with reference to the accompanying drawings and embodiments, which are illustrated in a simplified schematic representation of the basic structure of the invention, and therefore only the structures relating to the invention.

As shown in FIG. 1-7, a multi-entry type bar burner comprises: an elongated structure of a firearm 1 and a plurality of gas pipes 6 connected to the bottom of the firearm 1. The firearm 1 has a cavity 2 The hollow structure, the long-shaped firearms 1 are respectively provided with a row of fire holes 3 passing through the two sides, the fire holes 3 are arranged along the axial direction of the firearms 1, and the drums of the curved structure are arranged at the communication between the gas pipe 6 and the firearms 1 The chamber 7 is provided with a plurality of bulging chambers 7 arranged in the axial direction of the firearm 1. The bulging chamber 7 can assist in the thorough mixing of the gas with the air and provide a buffer for the gas to enter the inner chamber 2 from the gas tube 6.

The gas pipe 6 has a J-shaped structure, the gas pipe 6 has an air inlet 9, and the plurality of air inlets 9 face the axis of the fire extinguisher 1. This ensures that the entire stove can be a relatively narrow flat structure, which is conducive to the installation of the grill.

The top of the fire extinguisher 1 is provided with a top cover 5 having a width exceeding the width of the firearm 1 and a fire hole 3 opening on the fire extinguisher 1 below the top cover 5. The fire holes 3 are arranged in a line at the bottom of the top cover 5, so that due to the partial blocking of the top cover 5, the upper and lower areas on the side of the firearm 1 are divided into a high temperature zone and a low temperature zone, and the upper low temperature zone can be grilled. The heating material is preheated, and the lower high temperature zone can directly The barbecue heating is subjected to a flame burning.

The cross-sectional shape of the top cover 5 is a ridge-like structure with low middle and high sides. The axis of the inner cavity 2 is identical to the firearm 1. The cross-sectional shape of the inner cavity 2 matches the cross-sectional shape of the firearm 1 and is an inverted trapezoidal structure. Both sides are structures that are outwardly ridged. This configuration ensures maximum volume of the lumen 2 and matches the separation of the cap 5.

The bottom of the fire extinguisher 1 is provided with a convex fixing post 8 which is an inverted truncated cone. The fixing post 8 can quickly snap the firearm 1 into the outer frame body to fix the firearm 1.

The gas pipe 6 and the firearm 1 are connected with a baffle, and the baffle portion blocks the communication. The baffle functions to divert the gas mixed with air from the bulging cavity 7 so that the mixed gas faces the left and right ends of the inner cavity 2. flow.

The axis of the fire hole 3 extending outward from the inner chamber 2 is inclined downward so that the outer portion of the top cover 5 does not block the outer flame of the flame in the fire hole 3 (the outer flame is the region having the highest temperature in the flame).

The firearms 1 are also provided with air holes 4 at both ends. When the gas velocity provided by the inner cavity 2 is too large, when the mixed air is insufficient, a certain amount of air can be supplied through the air holes 4 to prevent the gas from burning insufficiently or yellow. Flame and other phenomena. The air hole 4 is circular, and the circular area is smaller than the cross-sectional area of the inner chamber 2. Such a structure makes it that the gas of the mixed air does not easily escape from the inner chamber 2, and can provide convenience for supplying a certain air.

In the first embodiment of the present invention, the gas pipes 6 are two, respectively symmetrically disposed on both sides of the center line of the firearms 1, and the intermediate position fixing column 8. Due to the large length of the firearm 1, the gas pipe 6 cannot be balanced. The two ends of the firearm 1 ensure that the gas supply at both ends of the firearm 1 is uniform. The two gas pipes 6 can ensure the uniform distribution of the gas in the inner cavity 2 of the firearm 1, the flame size and combustion of each fire hole 3. The situation is more consistent.

In the second embodiment of the present invention, the gas pipe 6 is three, the middle portion is fixed to the column 8, and one side of the positioning column is provided with two gas pipes 6, the air inlet holes 4 are in the same direction, and the other side is provided with a gas pipe. 6, air inlet Contrary to the other two. Due to the larger length of the firearm 1, the gas pipe 6 cannot balance both ends of the firearm 1 to ensure uniform supply of gas in each section of the firearm 1 in the axial direction, and the three gas pipes 6 can ensure the maximum degree of separation. The gas in the inner chamber 2 of the firearm 1 is evenly distributed, and the flame size and combustion condition of each fire hole 3 are relatively uniform.

According to the present invention, the number of the gas pipes 6 is set according to the length change of the fire extinguisher 1, and the larger the length, the larger the number of the gas pipes 6.

The above-described embodiments of the present invention are intended to be variously modified and modified without departing from the scope of the present invention. The technical scope of the present invention is not limited to the contents of the specification, and the technical scope must be determined according to the scope of the claims.
