The burner cap 170 may be simultaneously seated on the outer heads 121 and 131 and the inner head 151. That is, the burner cap 170 may simultaneously cover the outer heads 121 and 131 and the inner head 151.
FIG. 4 is a bottom perspective view of a burner cap according to an embodiment.
Referring to FIGS. 2 and 4, the burner cap 170 may include an outer cap 171, an inner cap 172 disposed inside the outer cap 171, and a connection wall 173 connecting the outer cap 171 to the inner cap 172.
The inner cap 172 may be disposed inside the outer cap 171. The outer cap 171 may have, for example, a circular ring shape, and the inner cap 171 may have a circular shape.
A first rib 174 may be disposed on a circumference of the inner cap 172, and a pair of second ribs 175 may be disposed on the connection part 173. The first rib 174 may protrude downward from a bottom surface of the inner cap 172, and the pair of second ribs 175 may protrude downward from a bottom surface of the connection part 173. The pair of second ribs 175 may be spaced apart from each other.
The outer cap 171 may be seated on the outer heads 121 and 131, and the inner cap 172 may be seated on the inner head 151. The connection part 173 may be seated on the mixed gas guide wall 153.
The outer cap 171 may cover the flame propagation passage P3. Also, the outer cap 171 together with the connection walls 126 and 127 of the outer head 121 and 131 may define the flame propagation passage P3.
The connection part 173 may cover an upper side of the mixed gas passage P2. Also, the connection part 173 together with the mixed gas guide wall 153 may define the mixed gas passage P2.
That is, the mixed gas guide wall 153 may have an opened upper side, and the connection part 173 may define an upper wall of the mixed gas passage P2. Also, the flame propagation passage P3 may have an opened upper side, and the outer cap 171 may define an upper wall of the flame propagation passage P3.
The mixed gas guide wall 153 may be disposed between the pair of ribs 175 in a state where the connection part 173 is seated on the mixed gas guide wall 153. Here, the pair of ribs 175 may contact the mixed gas guide wall 153 or be spaced apart from each other.
Thus, even though an external force is applied to the burner cap 170, the pair of ribs 175 may be hung on the mixed gas guide wall 153 to prevent the burner cap 170 from rotating.
Hereinafter, an operation of the burner according to the present embodiment will be described.
FIG. 5 is a sectional view taken along line A-A of FIG. 1, and FIG. 6 is a sectional view taken along line B-B′ of FIG. 1.
Referring to FIGS. 2, 5, and 6, a gas A supplied through the supply tube 111 may be sprayed into the mixed space 112 by the nozzle 117. The sprayed gas may be introduced into the mixed gas guide tube 154. Since the high-pressure gas is sprayed through the nozzle 117, a low pressure may be generated around the mixed gas guide tube 154. Thus, external air B may be introduced into the air passage P1 to flow into the mixing space 112, and thus, the external air together with the gas may be introduced into the mixed gas guide tube 154.
The mixed gas C (the mixture of the air and the gas) flowing into the mixed gas guide tube 154 may be spread into the inner head 151 after colliding with the inner cap 172. The mixed gas C supplied into the inner head 151 may flow into the outer heads 121 and 131 by the mixed gas passage P2.
When spark is generated in an ignition part (not shown), flame may be generated in the flame holes 124 and 134 defined in one outer wall of the outer heads 121 and 131. Then, the flame may be propagated into the flame holes 125 and 135 defined in the inner walls 123 and 133 of the outer heads 121 and 131.
Also, the generated flame may be propagated into the first flame holes 127 and 137 defined in the connection walls 126 and 136 and the second flame hole 138 (see arrow D) and then be propagated into the flame hole 155 of the inner head 151.
According to the present embodiment, since the flame is generated in the outer walls 122 and 132 of the outer heads 121 and 131 and the inner head 151, three flame groups may be generated.
According to the present invention, since the burner body and the burner head define the air passage, and the burner head and the burner cap define the mixed gas passage and the flame propagation passage, the burner may be manufactured with the minimum number of constitutions to simplify the structure of the burner. Thus, the manufacturing costs may be reduced, and the worker may easily assemble or disassemble the burner.
