DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stove burner formed by placing a burner cap on the head of a burner body.

[0002]

2. Description of the Related Art As a stove burner of this type, there is known a stove burner in which a burner cap is mounted on a head of a burner body. A discharge opening for discharging a mixed gas of fuel gas and primary air is formed at an upper portion of the head of the burner body. The burner cap is provided with a plurality of ridges radially arranged at predetermined intervals on the entire circumference on the back side thereof, and is placed on the discharge opening to form a plurality of flame holes by each ridge. Is formed.

Further, an ignition electrode is provided on the head of the burner body or on the stove body to which the burner body is attached, and on the back side of the burner cap, the ridge is provided corresponding to the ignition electrode. Are provided with an ignition flame portion having a shape different from the number of flame holes. Therefore, when placing the burner cap on the head of the burner body,
It is necessary to make the ignition flame hole exactly coincide with the position of the ignition electrode. However, if the burner cap is not correctly placed at the position, the position of the ignition electrode and the ignition flame hole is shifted. Therefore, smooth ignition and combustion may be hindered.

Therefore, conventionally, on the upper surface of the burner cap,
It is known that a mark indicating the position of the ignition flame hole is provided. That is, since the ignition flame hole is provided on the back side of this mark, when placing the burner cap on the head of the burner body, the mark is checked while checking the ignition electrode on the burner body side. A burner cap is placed so as to match the position of the ignition electrode.

However, even if the mark is provided on the upper surface of the burner cap, the ignition electrode must be directly visually recognized. According to this, when the burner cap is placed on the head of the burner body, the ignition electrode on the burner body side is hidden under the burner cap, and there is a disadvantage that the position of the mark and the ignition electrode are misaligned. .

In particular, when the ignition electrode is incorporated in the head of the burner body, the ignition electrode is hidden under the burner cap when the burner cap is mounted. However, even if the burner cap is misaligned, it is not possible to know the misalignment only by checking the mark.

A burner body of this type may be provided with a flame detector such as a thermocouple or a frame rod, and a burner cap mounted on the burner body corresponds to the flame detector. A flame detection hole is formed. Also in this case, there is the same disadvantage as in the case of the above-described ignition flame hole.

[0008] Further, in a device having both an ignition flame hole and a flame detection flame hole portion, even if the mark corresponding to the ignition flame hole portion is provided, for example, the user can use the ignition flame hole. When it is not possible to discriminate between the electrode and the flame detector, it is inconvenient to know where to match the mark.
Further, even if different marks are provided corresponding to the respective flame holes, it may be unclear which mark indicates which flame hole.
