Description

TECHNICAL FIELD

[0001] The present application relates to the field of furnace burner equipment, in particular to a compact burner and integrated villa stove. BACKGROUND

[0002] The existing integrated villa stove has a small internal space. Since the existing mixing pipe is usually vertically installed on the stove, its height is high, which increases the height occupied by the entire burner, i.e., the occupied space is large. In addition, in the prior art, the mixed gas in the mixing pipe directly enters the distribution chamber of the fire hole assembly through the chamber at the lower part of the fire hole assembly, the flow process is short, and the gas mixing is often not uniform, which affects the combustion effect. SUMMARY

[0003] The present application aims to solve the problems of the prior art, such as large occupied space and short mixed gas flow process, and provides a compact burner and integrated villa stove which reduces the height of the occupied space and increases the mixed gas flow process.

[0004] A compact burner is arranged on a stove and comprises a fire hole assembly and a mixing pipe in communication with the fire hole assembly. The mixing pipe is an L-shaped mixing pipe arranged horizontally on the stove. The fire hole assembly is at the bending part of the inner side surface of the L-shaped mixing pipe and in contact with the inner side surface of the L-shaped mixing pipe. One end of the L-shaped mixing pipe is provided with an air inlet and a gas inlet, and the inner side surface of the other end is provided with a first mixed gas inlet in communication with the inside of the fire hole assembly. The lower part of the fire hole assembly is provided with a chamber.

[0005] A shunt device is embedded in the bottom of the chamber of the fire hole assembly. The shunt device comprises a top plate, a baffle and a bottom plate. The top plate and the bottom plate are fixed and separated by a reinforcing rib or a fastener. The outer diameter of the bottom plate is larger than that of the bottom of the fire hole assembly, and the diameter of the top plate is smaller than that of the chamber. The side surface of the chamber is provided with a second mixed gas inlet matched with the first mixed gas inlet. The height of the top plate is lower than that of the top of the chamber, and the height of the top plate is higher than or equal to the height of the second mixed gas inlet. The center of the top plate is provided with a mixed gas outlet in communication with the upper part of the fire hole assembly. The inner wall of the chamber, the top plate and the bottom plate of the shunt device form a shunt chamber. The baffle is arc-shaped and arranged in the shunt chamber and corresponds to the side of the second mixed gas inlet, so that the mixed gas flowing out of the second mixed gas inlet is shunted left and right in the shunt chamber.

[0006] In one of the embodiments: the fire hole total assembly includes an outer ring, an inner ring and a fire hole assembly. The outer ring is sleeved outside the inner ring, and the inner side wall of the outer ring and the outer side wall of the inner ring form a distribution cavity. The top of the distribution cavity is a closed structure and the bottom is an open structure. The bottom of the outer ring extends downward to form a chamber with an open bottom structure, and the chamber is in communication with the distribution cavity. The inner ring is provided with an annular hole. The annular hole is provided with a fire hole assembly, which is a multi-hole tube fire hole assembly or a laminated fire hole assembly.

[0007] In one of the embodiments: the L-shaped mixing pipe includes a long pipe and a short pipe arranged vertically and in communication, and the long pipe and the short pipe are respectively in contact with the outer side surface of the fire hole total assembly. The long pipe and the short pipe are square pipes or circular pipes.

[0008] In one of the embodiments: the central angle of the arc-shaped baffle is 90°-180°.

[0009] In one of the embodiments: the number of the flow splitting devices is at least one.

[0010] An integrated villa stove includes the above-mentioned burner.

[0011] The advantages and beneficial effects of the present application are:

[0012] The L-shaped mixing pipe of the present application is arranged horizontally on the stove, and the fire hole total assembly is arranged at the bending position of the inner side surface of the L-shaped mixing pipe and in contact with the inner side surface of the L-shaped mixing pipe. This design reduces the height occupied by the entire burner, i.e., the occupied space is small.

[0013] The flow splitting device is embedded in the chamber corresponding to the bottom of the fire hole total assembly. The baffle is arranged in the flow splitting cavity and corresponds to the side of the second mixed gas inlet, so that the mixed gas flowing out of the second mixed gas inlet is split left and right in the flow splitting cavity. This design increases the flow process of the mixed gas in the lower chamber of the fire control total assembly, and makes the mixed gas mixing more uniform and the combustion effect better.

[0014] The mixed gas outlet of the flow splitting device is in the center of the top plate. After the gas flow passes through the mixed gas outlet, it rises completely symmetrically around the center, ensuring that the flame is symmetrical and the flame shape is more beautiful.
