Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a gas burner, and more specifically to a parent-child burner used in gas stoves and the like.

[Prior Art] As shown in FIG. 6, a gas burner consisting of a ring-shaped main burner A and a slave burner C provided within the inner wall B of the ring is known, for example, from Utility Model Application No. 56-85125. ing. In such a gas burner, in order to ignite the child burner C, a method is generally used in which the ignition flame of the ignition burner is blown into the inner wall B, and in order to cut off the gas when the burner misfires. A heat detection element such as a thermocouple is placed facing the flame,
It is also well known that a safety valve is controlled by the output from the heat detection element.

[Problems to be Solved by the Invention] In this case, the ignition flame from the ignition burner extends along the inner wall B of the ring body of the parent burner, reaches the heat detection element, and lifts the flame that heats the element. As a result, the heat detection element could not generate enough output to keep the safety valve open.

[Structure of the device] Consists of a master burner of an annular body and a sub-burner within the inner wall of the annular body, and the sub-burner is equipped with a misfire safety device including a heat detection element, and is blown into the inner wall of the annular body from the ignition burner. In a device that is ignited by an ignition burner flame, a partition member is provided within the inner wall of the ring between the heat detection element and the ignition burner.

[Operation] According to the present invention, even if the ignition burner flame of the ignition burner tries to extend along the inner wall of the parent burner of the ring body,
The partition member does not extend to the heat detection element, and the flame of the child burner that heats the heat detection element can be stabilized.

[Effects of the invention] The gas burner configured as described above has the following effects.

The ignition burner flame of the ignition burner for the child burner inside the ring body wall of the ring body main burner extends along the ring body wall in the direction of the heat detection element, but since a partition member is provided in the middle, it heats the heat detection element. The flame of the child burner is hardly affected by the ignition burner flame, and it is possible to stably heat the heat detection element and obtain a stable output from the element.

[Embodiment] Reference numeral 1 denotes a ring-shaped main burner, and a child burner 3 is provided inside the ring-shaped inner wall 2. Reference numeral 5 denotes a heat detection element, such as a thermocouple, of the misfire safety device 4 which shuts off the gas if the child burner 3 misfires. Reference numeral 6 denotes a safety valve of the device 4, which is held open by the electromotive force generated when the heat detection element 5 is heated by the flame 3a of the slave burner 3.

An ignition burner 7 ignites the slave burner 3, and the ignition flame 7a of the ignition burner 7 is blown into the inner wall 2 of the ring body of the master burner 1.

A partition member 8 is provided within the inner wall 2 of the ring, and is provided between the heat detection element 5 and the ignition burner 7. As a result, the ignition flame 7a of the ignition burner 7 is blown into the inner wall 2 of the ring for igniting the child burner 3, and even if the ignition burner flame 7a extends along the inner wall 2, the partition member 8 is provided. Therefore, the ignition burner flame 7a stops there, or weakens, and the flame heating the internal heat detection element 5 of the flame 3a of the small burner 3 burns stably.

In this embodiment, the ignition burner 9 is also placed in front of the main burner 1, so that the main burner 1 and the child burners 3 can be ignited independently. Also, 10 is the parent burner 1
A misfire in the main burner 1 is also detected using the heat detection element. In FIG. 5 showing another example, the partition member 8 is provided integrally with the main burner 1.
