Embodiment Construction

[0016] Referring to FIG. 1 , 1 denotes a stove main body, 2 denotes a panel covering the upper surface of the stove main body 1 , and 3 denotes a burner for a stove. In the panel 2, the opening 2a for burners is opened. In addition, on the panel 2, a bracket (not shown in the figure) is placed so as to surround the burner opening 2a. Furthermore, the cooking vessel placed on the stand is heated by the burner 3 .

[0017] The burner 3 has a burner body 4 inserted through the burner opening 2 a and a burner head 5 on the burner body 4 . On the peripheral surface of the burner head 5, as shown in FIG. 2, a plurality of flame holes 6U, 6L in upper and lower layers are provided, and the plurality of flame holes 6U, 6L in the upper and lower layers are spaced apart in the circumferential direction. Here, the upper layer flame holes 6U are not provided at multiple positions corresponding to the bracket claws of the bracket in the circumferential direction, so as to prevent the flam...

Abstract

The invention relates to a burner for a stove. The periphery of a burner head (5) is provided with an upper layer and a lower layer of multiple flame holes (6U), (6L), the upper layer and the lower layer of multiple flame holes (6U), (6L) have intervals in the peripheral direction, and mixed gases the air excess rate of which is less than 1 are supplied to the upper inflame holes and the lower inflame holes respectively from different hybrid tubes (7U), (7L). The burner for the stove solves the problem that the burn can prevent flame length of the upper flame holes from becoming long without expanding the outside diameter of the burner head, does not produce the condition that heat distribution becomes poor, and can improve heat efficiency. The burn adopts the solution that the air excess rate of the mixed gases supplied to the upper inflame holes (6U) is bigger than that of the mixed gases supplied to the lower inflame holes (6L), and preferably, the air excess rate of the mixed gases supplied to the lower inflame holes (6L) is smaller than 0.7, while the air excess rate of the mixed gases supplied to the upper inflame holes (6U) is bigger than 0.7.

Description

technical field [0001] The present invention relates to a burner for a stove capable of adjusting the fire power in a wide range from strong fire to weak fire. Background technique [0002] In the past, as such a burner for a stove, there is known a burner in which a plurality of upper and lower layers of flame holes are provided on the peripheral surface of the burner head, and the upper and lower layers of a plurality of There are intervals between the flame holes in the circumferential direction, and the mixed gas with an excess air ratio (primary air volume / theoretical air volume) of less than 1 is provided to the upper layer flame holes and the lower layer flame holes through different paths, and at the same time, the total amount of the lower layer flame holes The area is smaller than the total area of ​​the flame holes in the upper layer (for example, refer to Patent Document 1). Through this burner, the firepower can be changed in a wide range from a strong fire sta...
