Description

[Detailed explanation of the idea] The present invention relates to a hot water boiler.

A conventional boiler of this type is as shown in Fig. 6, and a burner B is provided on the side of the boiler body A. The tip of the burner B is inserted into a combustion chamber C, and the combustion gas is passed through a baffle device. It passes through the gap between the combustion chamber cover F and the inner shell E of the boiler, and is discharged from the exhaust port G provided in the center of the combustion chamber lid F to the exhaust stack.

By welding a plurality of carved metal fittings H to a part of the inner body E of the boiler, and making the dimensions after the metal fittings H are attached larger than the diameter of the baffle device and smaller than the diameter of the combustion chamber cover F, the panfur The device can be suspended by metal fittings H, and the panfur device is also held by a plurality of support plates I.

Place a heat insulating material J on the combustion chamber cover F, install a heat insulating material holding cylinder K made of a perforated plate around the exhaust port G, cover the top with an exterior lid, and screw this lid onto the exterior plate M. A baffle system was used to maintain the structure.

According to the above configuration, the baffle device was maintained in the vertical direction, but no measures were taken against rotation in the circumferential direction, so the increase in pressure in the combustion chamber C at the time of ignition The accompanying vibration causes the entire baffle device to rotate, causing the combustion chamber lid F to rotate.
There is a risk that the upper heat insulating material J will wear out, or that the cut-out metal fittings H or the edges of the combustion chamber lid F will be deformed due to the vibrations, causing the baffle device to hit the can wall of the boiler 1 or fall. There is.

The present invention solves the above-mentioned conventional drawbacks, and examples thereof will be described below.

As shown in FIGS. 1 to 5, a burner 2 is provided on the side surface of a hot water boiler main body 1 formed by an outer shell 1C and an inner shell 1a inside the outer shell 1C.

The burner 2 performs combustion in the combustion chamber 3 in the inner shell 1a, and the high-temperature combustion gas generated by this is meandered 5 by the baffle device 4, and heats up the water and heat between the inner and outer shells 1a and Ic. While being replaced, the fuel proceeds to the upper part, passes through an exhaust port 6a formed in the center of the combustion chamber lid 6, passes through an exhaust inner pipe 7 provided outside the exhaust port 6a, and is discharged to the outside from an exhaust pipe connection part 8. .

A notch 9 is provided in a part of the periphery of the combustion chamber lid 6.

In addition, a through hole 12 is formed to pass through the upper end of the metal rod 11 from which the resistance plate 4a of the baffle device 4 and the partition plate 10 are suspended.
A plurality of baffles are formed on the combustion chamber lid 6 and a baffle device is suspended from the combustion chamber lid 6 into the combustion chamber 3.

The combustion chamber lid 6 is mounted on a tapered portion 1b that is wide at the top and narrows at the bottom, provided at the inner shell 1a of the boiler main body 1.

Furthermore, the outer shell 1 of the boiler main body 1 corresponds to the notch 9.
In part e1, a metal fitting 14 with a hole for screwing (not shown) and an abbreviated shape with a mounting hole 13 at the - end is provided, and the screw hole and the mounting hole 13 of the metal fitting 14 are aligned with each other. , screw 15
Fix it with.

The lower end of the detent fitting 14 of the baffle device 4 is
It is inserted into the notch 9 of the combustion chamber lid 6.

16 is a heat insulating material placed on the combustion chamber lid 6; 17 is an exterior body; 1
Reference numeral 8 denotes an exterior lid, which is screwed to the exterior body 17.

19 is a heat insulating material.

According to the above configuration, the baffle device 4 includes a detent fitting 7 fixed to the boiler main body 1 in the notch 9 of the combustion chamber lid 6.
By locking the lower end of the insulation material 1, it is possible to prevent rotation in the circumferential direction, and the panfur device 4 will not rotate during transportation or due to vibrations caused by high pressure at the start of combustion.
6 and deformation of the combustion chamber cover 6 can be prevented.

In addition, since the baffle device 4 does not rotate but shifts to a fixed position, it is possible to prevent the occurrence of uneven exhaust gas flow resistance that would adversely affect combustion.

As described above, in the present invention, a part of the tapered part that is wide at the top and narrow at the bottom is provided in the inner barrel part, and the combustion lid is placed on this tapered part, so a support means for the combustion lid is separately provided. It is easy to install, the configuration is simple, and the J1 strike can be reduced.
Moreover, since it also prevents the combustion lid from rotating, this simultaneous movement of the combustion lid can cause problems such as misalignment of the baffle device from its normal position in the combustion chamber, worsening the combustion condition. do not have.
