Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a burner for a gas stove.

[0002]

[Prior art]

 The conventional burner shown in FIG. 4 is provided with a downwardly opening supply hole (20) at the center of the burner (2) on the cylinder. A plurality of outer peripheral holes (7) and inner peripheral holes (6) are provided on the upper surface of the burner (2) concentrically with the burner (2). Each outer peripheral hole (7) and inner peripheral hole (6). Is connected to the supply hole (20). The fuel gas is supplied from below the burner (2) through the supply hole (20) to the outer peripheral hole (7) and the inner peripheral hole (6). The fuel gas ejected from the outer peripheral hole (7) and the inner peripheral hole (6) is ignited to burn the fuel gas.

[0003]

[Problems to be solved by the device]

 The fuel gas is ejected from the outer peripheral hole (7) and the inner peripheral hole (6) of the burner (2) and burned. However, the oxygen required to burn the fuel gas is supplied from the peripheral part of the burner (2), so most of the oxygen is used to burn the fuel gas ejected from the outer peripheral hole (7), Oxygen is not sufficiently supplied to the fuel gas ejected from the holes (6). Therefore, there was a problem that the color of the flame in the inner peripheral hole (6) became red and the combustion was incomplete. An object of the present invention is to provide a mechanism for completely burning the fuel gas ejected from the inner peripheral hole.

[0004]

[Means for solving the problem]

 The burner (2) has a plurality of inner peripheral holes (6) and outer peripheral holes (7) for ejecting fuel gas. A through hole (8) for supplying oxygen from below is opened at the center of the burner (2) surrounded by the inner peripheral hole (6). Eccentric from the center of the burner (2), a gas supply hole (42) for supplying fuel gas to the inner peripheral hole (6) and the outer peripheral hole (7) is provided, and at the outlet of the gas supply hole (42). The diffusion plate (5) is protruding.

[0005]

[Action and effect]

 During the combustion of the fuel gas, oxygen-containing air is supplied from below through the through hole (8). Therefore, the oxygen required for the flame of the inner peripheral hole (6) is supplied from the through hole (8), so that the flame of the inner peripheral hole (6) does not become incomplete combustion as in the conventional case. Further, since the through hole (8) is opened in the central portion of the burner (2), the gas supply hole (42) is eccentric from the central portion of the burner (2), but is supplied to the burner (2). The generated fuel gas hits the diffusion plate (5), and the fuel gas whose flow direction is regulated by the diffusion plate (5) flows into all the inner peripheral holes (6) and the outer peripheral holes (7). That is, even though the gas supply holes (42) are eccentric, the fuel gas is uniformly supplied to all the inner peripheral holes (6) and the outer peripheral holes (7).

【Example】

 Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings. FIG. 3 is an overall perspective view of the stove (1) including the burner (2). A burner (2) is provided in the center of the stove (1), and an operating knob (10) for adjusting the supply of fuel gas to the burner (2) is provided on the front of the stove (1). A spark plug (9) for igniting the fuel gas is provided on the side of the burner (2). As shown in FIGS. 1 and 2, the burner (2) comprises a burner head (3) and a burner body (4) with which the burner head (3) is fitted. The burner head (3) integrally includes an upper piece (30) that shrinks downward and a cylindrical lower piece (31). The upper piece (30) is provided with an opening (34) in the center so that the thickness is substantially uniform, and a through hole (8) is formed in the bottom surface of the lower piece (31). Around the opening (34) of the upper piece (30), a plurality of inner peripheral holes (6) are vertically penetrated concentrically with the upper piece (30), and the inclined surface (32) which is the outer circumference of the upper piece (30). ), A large number of slit grooves (33) are opened in the inclined direction.

A triangular support protrusion (44) is provided so as to project from the side portion of the burner body (4), and the lower surface of the support protrusion (44) is aligned with the lower surface of the burner body (4). A tapered fitting hole (40) narrowing toward the bottom is formed on the upper surface of the burner body (4), and the fitting hole (40) is connected to the cylindrical hole (43) at the bottom. The cylindrical hole (43) is formed so that the lower piece (31) is closely fitted, and the air supply hole (41) is vertically penetrated through the center of the bottom surface of the cylindrical hole (43). The lower part (31) of the burner head (3) is fitted in the cylinder hole (43), and the through hole (8) and the air supply hole (41) are aligned with each other, and the burner head (3) is mounted on the bottom surface of the cylinder hole (43). Placed. In this state, as shown in FIG. 2, the inclined surface (32) of the upper piece (30) and the upper edge of the fitting hole (40) are in contact with each other, and the side surface opening of the slit groove (33) is the outer periphery. The hole (7) is formed. Inside the support protrusion (44), a gas supply hole (42) is opened vertically at the side of the cylindrical hole (43). That is, the gas supply hole (42) is eccentric from the center of the burner (2). Above the gas supply hole (42), the diffusion plate (5) projects from the side portion of the fitting hole (40). The lower surface of the diffusion plate (5) and the side surface of the fitting hole (40) are connected in a smooth arc shape, and the tip of the diffusion plate (5) is formed so as not to cover the inner peripheral hole (6). Has been done.

(Ignition / Combustion) Ignition of the burner is performed as follows. By operating the operation knob (10) on the front of the stove (1) shown in FIG. 3, fuel gas is sent from the outside of the burner (2) to the gas supply hole (42). As shown in FIG. 2, the fuel gas ejected upward from the gas supply hole (42) into the fitting hole (40) hits the lower surface of the diffusion plate (5). The fuel gas that has been regulated to flow upward by the diffusion plate (5) flows along the peripheral surface of the fitting hole (40) and the space between the fitting hole (40) and the burner head (3). Fill up with. The fuel gas filling the space is blown upward from the inner peripheral hole (6) of the burner head (3) and is also ejected upward through the outer peripheral hole (7) formed by the slit groove (33). . On the other hand, air is supplied from below the burner body (4) to the upper central portion of the burner head (3) through the air supply hole (41), the through hole (8) and the opening (34).

The fuel gas is ignited by the ignition plug (9) shown in FIG. 3 in a state where the fuel gas is ejected from the inner peripheral hole (6) and the outer peripheral hole (7). As shown in FIG. 2, oxygen contained in the air is supplied to the flame in the inner peripheral hole (6) through the air supply hole (41) and the through hole (8). The flame that burns the fuel gas ejected from the outer peripheral hole (7) receives the oxygen contained in the air in the peripheral portion of the burner body (4) and continues to burn, as in the conventional case.

Oxygen required for burning the fuel gas ejected from the inner peripheral hole (6) is supplied from the outside of the burner body (4) through the through hole (8), so that the conventional flame is used. Oxygen supply to the inner peripheral hole (6) is not interrupted by the flame in the outer peripheral hole (7), and the flame in the inner peripheral hole (6) burns completely. Further, the fuel gas ejected from the gas supply hole (42) into the fitting hole (40) of the burner body (4) hits the diffusion plate (5) and flows along the peripheral portion of the fitting hole (40). Therefore, the fuel gas is evenly filled in the fitting hole (40), and the fuel gas is evenly supplied to the inner peripheral hole (6) and the outer peripheral hole (7).

The above description of the embodiments is for explaining the present invention, and should not be construed as limiting the invention described in the scope of the utility model registration request or reducing the scope. Further, the configuration of each part of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made within the technical scope described in the scope of claims for utility model registration.
