Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved structure of a burner support device that facilitates the installation of a burner into a hot water boiler or the easy inspection and cleaning of the burner.

An embodiment will be described below with reference to the drawings. Reference numeral 1 denotes a hot water storage tank consisting of a cylinder 1a having an inverted U-shaped cross section and a bottom plate 1b curved inward to the cylinder, closing the opening at the lower end of the cylinder 1a, and receiving water from a water supply port 2. , the hot water is taken out from the tap 3 by that much amount.

Reference numeral 4 denotes support legs for supporting the hot water storage tank 1, and a plurality of support legs 4 are attached to the outer peripheral portion of the bottom plate 1b via substrates 5, which will be described later.

Reference numeral 5 denotes a substrate that partitions the lower space of the hot water storage tank 1, and the base plate 1
A heating chamber 6 is formed between the support leg 4 and the back plate 7 attached to the support leg 4, and an equipment chamber 8 is formed between the support leg 4 and the back plate 7.

An opening 9 is provided in the center of the substrate 5, a combustion tube 10 is attached from the periphery of the opening toward the heating chamber 6, and a heat-resistant packing 11 made of asbestos or the like is installed on the lower surface of the periphery of the opening.

Reference numeral 12 denotes a head 12 having a rotary atomizer that atomizes liquid fuel, a burner motor 12a, a blower 12b, and a flame port.
A burner equipped with
Annular mounting plate 1 pressed from the side via packing 11
3 is attached to the outer periphery of the head 12C, and the mounting plate 1
A hook portion 14 is provided on the outer periphery of the hook portion 3 at a proper location, and an insertion hole serving as a screw fastening portion 15 is provided on the opposite side corresponding to the hook portion 14, respectively.

Reference numeral 16 denotes a support fitting for hooking the hook 14, which is attached to the lower surface of the board 5.

Reference numeral 17 denotes a series of communication holes bored in the base plate 5, the packing 11, and the flange piece of the combustion tube 10 corresponding to the screw fixing part 15, and a nut 18 is fixed to the flange piece above the communication hole 17. .

Reference numeral 19 denotes an exterior body fixed to the support leg 4. A heat insulating material 20 is attached to the inside corresponding to the hot water storage tank 1, and an opening for putting in and taking out the burner 12 is provided on the side surface corresponding to the equipment chamber 8 at the bottom of the hot water storage tank 1. An opening/closing door 21 is attached to the opening.

22 is an exhaust pipe communicating with the heating chamber 6; 23 is an intake pipe 22 communicating with the suction pipe 24 of the burner 12; 23 projects outside the exterior 19 and is connected to the intake and exhaust pipes.

Reference numeral 25 is a baffle plate attached to the combustion tube 10 that partitions the inside of the heating chamber 6 into upper and lower parts, and is used to bring the combustion exhaust gas into contact with the bottom plate 1b of the hot water storage tank 1 for a long time to improve heating efficiency.

26 is a pedestal fixed to the back plate 7 below the burner 12 and has an inclined mounting surface 26' that supports the burner 12 in an inclined state;
Moreover, a slit 27 is provided to allow the suction pipe 24 to escape.

Reference numeral 28 is a bolt that is screwed into the nut 18 and attaches the burner 12 to the base plate 5, and a knob portion 28 that can be removed by hand.
' is provided.

The present invention has the above structure, and the installation and removal of the burner will now be explained.

Open the opening/closing door 21 of the exterior 19 and insert the burner 1 through the opening.
2 is placed on the pedestal 26 at an angle, and the suction pipe 24 of the burner 12 is inserted into the slit 27.

Then, the suction pipe 24 is guided through the slit 27 and the pedestal 26 is
The hook part 14 is hooked onto the support metal fitting 16 by sliding the upper part in an inclined state.

(See FIG. 2) Next, the burner 12 is rotated around the fulcrum of the hook portion 14 and the support fitting 16, and the mounting plate 13 is brought into close contact with the periphery of the bottom opening of the substrate 5 via the packing 11.

Thereafter, by inserting the bolt 28 into the threaded portion 15 and the communication hole 17 and screwing it into the nut 18, the burner 12 is attached to the base plate 5 with its head 12C facing into the combustion tube 10.

Thereafter, the intake pipe 23 is connected to the suction pipe 24, and the fuel pipe and electrical connections are made.

Therefore, the bottom plate 1b of the hot water storage tank 1 is heated by the combustion flame from the flame opening of the burner 12, the exhaust gas is discharged to the outside through the exhaust pipe 22, and the water in the water storage tank 1 is heated.

On the other hand, when removing the burner 12, remove the intake pipe 23 and the fuel pipe, then remove the bolt 28 and hook the hook part 14 to the support metal fitting 16 as shown in FIG.
The burner can be rotated and supported in an inclined position on the inclined mounting surface 26' of the pedestal 26, and it can be used in this state for simple inspection and cleaning, and if the burner is to be taken out completely, the outer hanging part must be removed. Just take it out from the opening in the exterior.

Since the present invention is as described above, the burner can be installed and removed with simple operations, and inspection and cleaning can be easily performed.

Although the bolt is screwed into the nut on the board side, the same effect can be obtained by suspending the bolt from the board, inserting the bolt into the mounting hole on the burner side, and screwing the nut into the bolt from below the mounting plate.
