Description

DETAILED DESCRIPTION OF THE INVENTION [Purpose of the Invention] (Industrial field of application) The present invention provides an upper combustion cylinder having a lower combustion cylinder as a primary combustion section and a glass outer cylinder continuously formed above the lower combustion cylinder. The present invention relates to an oil burning appliance to be used as a secondary combustion unit.

(Prior Art) This kind of petroleum combustion equipment is disclosed, for example, in Japanese Utility Model Publication No. 62-1527.
As shown in the publication, a double-tube lower combustion cylinder is used as a primary combustion section, and an upper combustion cylinder provided with a diffusion cylinder surrounded by a glass outer cylinder is connected as a secondary combustion section above the lower combustion cylinder. The incompletely combusted gas rising from the primary combustion part is diffused and burned in the upper secondary combustion part to complete the re-combustion, and the white-yellow flame of the secondary combustion part generated by diffusion combustion is outside the glass. It has the feature that it is transmitted to the outside through the tube and the visual heating effect is improved.

By the way, since such an oil burning appliance performs different combustion in the upper and lower combustion cylinders, the upper combustion cylinder is divided into the lower combustion cylinder with a partition bottom plate or the like, and a predetermined gap is provided between them. An air introduction path is secured to the secondary combustion section so that fresh air can be introduced from the outside of the combustion cylinder. For this reason, the glass outer tube forming the upper combustion tube is held on the partition bottom plate independently of the lower combustion tube, but this glass outer tube is retained even when retaining the upper part and tilting the device. A plurality of stanchions planted in the partition plate so as not to separate, and a support ring and a top plate supported by the stanchions are fitted to the open upper end portion of the glass outer cylinder so that the glass outer cylinder is positioned above the partition bottom plate. It is held so as to be sandwiched.

(Problems to be solved by the invention) As described above, in order to hold the glass outer tube forming the upper combustion tube, in addition to using the pillars planted in the partition plate or the like, the glass outer tube is fitted to the open upper end portion of the glass outer tube. Since the support ring and the top plate are used, not only the number of parts for holding the support ring increases but also the assembling and processing become complicated, which causes a cost increase. Further, from the appearance, it cannot be said that it is not always preferable because the original function of the glass outer cylinder is deteriorated by the amount that the support ring and the top plate are fitted into the upper end open portion.

The present invention is intended to improve the problems of the above conventional configuration,
An object of the present invention is to make it possible to hold the glass outer cylinder with a simple structure without increasing the number of parts.

[Means for Solving the Problem] (Means for Solving the Problem) A lower combustion cylinder including an inner flame cylinder, an outer flame cylinder, an outer cylinder, and the like serves as a primary combustion portion, and is communicated with the inner flame cylinder to project upward. A diffusion cylinder and a glass outer cylinder whose upper and lower ends are open and surrounds the outside of the diffusion cylinder, and the lower combustion cylinder for mounting the lower end of the glass outer cylinder on the upper surface side and ensuring an air introduction path on the lower surface side. An upper end side of the combustion cylinder composed of an annular partition bottom plate disposed above a predetermined interval as a secondary combustion section, and incomplete combustion gas rising from the primary combustion section is diffused and burned. A plurality of glass outer cylinder holders made of an elastic material having a retaining piece bent outward and a bent leg piece on the lower end side are provided, and the partition bottom plate is attached on the lower combustion cylinder. A plurality of spacing members are provided,
Corresponding screw holes and bottom plate attachment holes are provided at the corresponding portions of the space holder and the partition bottom plate, and the partition bottom plate is provided with holder locking holes close to the attachment holes. When attaching the bottom plate with screws, insert the bent leg piece of the glass outer cylinder holder into the holder locking hole, and position it on the space holder with the back plate of the partition bottom plate attached. The glass outer tube holder is planted and fixed together with the partition bottom plate, and the upper end side of the glass outer tube placed on the partition bottom plate is disengaged from the inside by the retaining piece on the upper end side of the glass outer tube holder. It is designed to be held as much as possible.

(Operation) According to the present invention, the glass outer cylinder holder is attached at the same time as the partition bottom plate is attached by the above-mentioned construction, and the holder is attached only to the bent leg pieces on the lower end side and the upper end side provided with the retaining piece. Since it is planted and fixed on the partition bottom plate in a free state, after assembling the glass outer cylinder, push the upper end side inward after this mounting and fixing, and insert this glass outer cylinder holder as a guide inside the glass outer cylinder. If the glass outer cylinder is positioned on the partition bottom plate, the retaining piece of the glass outer cylinder holder that is bent outward protrudes at the upper end of the partition, and the retaining piece is held upwards to prevent it from coming out upward. It is something.
