Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an oil stove having a removable burner.

[Prior art]

As shown in Fig. 1, in a conventional kerosene stove, the burner 3 is simply mounted on the upper ends of the core and inner and outer cylinders 1 and 2, so the height of the burner 3 is increased and the center of gravity 4
The higher the position, the more the stove body (not shown)
Even if it is slightly tilted, the center of gravity 4 will exceed the fulcrum 5 (the mounting position of the outer flame tube 6 of the burner 3), and it will easily fall off.

However, the burner 3 is extremely dangerous because it is at a high temperature during combustion, and in order to prevent the burner from falling off as described above,
The outer cylinder 7 of the burner 3 has a significantly large diameter and is supported by a support member (not shown) attached to the outer periphery of the core outer cylinder 2.

However, with such a configuration, the outer cylinder becomes extremely large and the supporting member also has a size commensurate with this, resulting in a drawback that the cost becomes extremely high.

〔the purpose〕

The present invention was developed in view of the above-mentioned points, and is designed to prevent the burner from tipping over or falling off without particularly increasing the diameter of the outer cylinder.

〔Example〕

Figures 2a and 2b show the overturn prevention mechanism of the kerosene stove of the present invention, in which 8 is a core cap attached to the upper end of the inner core cylinder 1, a central hole 9, and a number of peripheral holes 10, 10, . . . is drilled. Reference numeral 11 denotes a fall prevention plate serving as a convex fall prevention member, and is spot welded to the center top 8 by a pair of lower mounting pieces 12, 12. Reference numeral 13 denotes a lower protrusion having a length approximately equal to the diameter of the center hole 9, and is fitted into the center hole 9 to help position the fall prevention plate 11.
In addition, the fall prevention plate 11 may be fixed to the core top 8 by using a screw that fixes the core top 8 to the core inner cylinder 1.

14 is a lower ventilation hole plate which serves as a positioning member and is spot-welded to the inner peripheral surface of the inner flame cylinder 15 of the burner 3;
A ventilation hole 16 is bored in the center. The diameter of this vent hole 16 is slightly longer than the width (length) of the upper narrow part 11a of the fall prevention plate 11 (Δt=0.3 mm to 0.4 mm), When placed on top, the upper narrow part 11a is placed on the ventilation hole
It protrudes with a gap of Δt. In addition,
Both corners of the upper narrow part 11a are rounded, so when the burner 3 is placed, the upper narrow part 11a is rounded.
The insertion and fitting of a into the ventilation hole 16 can be performed smoothly.

Further, in the fall prevention plate 11, the lower part of the upper narrow part 11a is a lower wide part having a width close to the diameter of the centerpiece 8. Therefore, when placing the burner 3, even if the inner flame tube 15 is slightly misaligned, its lower end will align with the outer periphery (shape) of the fall prevention plate 11 to the core top 8.
Since the burner 3 reaches the top, the burner 3 is correctly positioned at a predetermined position, that is, at the outer peripheral flange portion of the core 8, as shown in FIG. 2a.

That is, the fall prevention plate 11 serves to prevent the burner 3 from falling and also to position the burner when it is placed.

Now, in the above state, even if the stove body is tilted, the periphery of the ventilation hole 16 will be
Since the burner 3 is contacted and locked to the narrow upper part 11a of the burner 3, it will not fall off even if the burner 3 is tall and has a high center of gravity. In addition, if the stove body is completely overturned, the upper narrow part 11a will be turned sideways or slightly downward, so that the upper narrow part 11a will act as a guide and cause the burner 3 to fall off. This is useful for instantly extinguishing fires in the event of an earthquake, etc.

Further, since Δt is very precise, when the burner 3 is placed, its positional relationship with the core inner and outer cylinders 1 and 2 is accurate, and stable and uniform combustion can be achieved. In particular, as shown in FIG. 3, the width of the collar 2a of the outer core tube 2 is widened, the ignition device 17 is fixed to this portion, and the portion of the outer flame tube 6 corresponding to the ignition device 17 is expanded.
In the case of type A, the positioning of the burner 3 is extremely important, and in this sense, the above-mentioned fall prevention plate 1 is
The function of number 1 is important.

(1) Therefore, as shown in Fig. 4a and b, there is a
8, protruding 19 per front and 1 per front
A cut 20 is formed diametrically along 9.
The positional relationship between the respective perforations 18 and 19 and the handle 21 of the burner is as shown in the figure, so when placing the burner 3 on the upper end of the inner core and outer cylinders 1 and 2, please refer to Figure 2a,
It is placed smoothly in the same manner as shown in b. When igniting the match, the burner 3 is rotated in the direction of the arrow as shown in FIG. At this position, burner 3 A
If you lift it up by the point, you will see the notch 2 of the ventilation hole 16.
Since 0 corresponds to the fall prevention plate 11, the burner 3 can be lifted smoothly without being hindered by the fall prevention plate 11. That is, the abutments 18 and 19 serve as contact portions for positioning the burner 3 in the rotational direction.

Incidentally, since the match ignition is not normally required, the burner 3 may be placed in the position shown in FIG. 4a.

(2) As shown in FIG. 5, a fall prevention plate 23 made of a wire rod bent into a convex shape may be installed on the core top 8.

〔effect〕

As described above, according to the present invention, it is possible to easily prevent the burner from falling off and falling over without increasing the diameter of the outer cylinder or the like.

Furthermore, the fall prevention member also serves as a guide to guide the burner to a predetermined position when placing the burner on the core and inner and outer cylinders, so it not only allows the burner to be always positioned at the predetermined position, but also helps in positioning the burner in its rotational direction. can also be done.
