Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a water heater, and more particularly to a water heater having a removably attached combustor.

[Background of the idea]

Normally, in water heaters, in order to obtain stable combustion and improve thermal efficiency, the combustor is installed within the heat exchanger so that the flame opening is above the lower end of the cylindrical heat exchanger. It is arranged.

On the other hand, various types of combustors have been put into practical use that vaporize kerosene and burn the vaporized gas at the flame nozzle.
When burning kerosene vaporized gas, there are problems in that soot and tar tend to be generated, which can easily clog the flame opening of the combustor and vaporization, so it is extremely important that maintenance is easy. It is.

Therefore, the present invention was devised in view of the above circumstances, and its purpose is to position and fix the flame port of the combustor above the lower end of the heat exchanger, and to fix the heat exchanger. To provide a water heater whose combustor can be freely removed even after the water heater has been used, and whose maintenance can be performed extremely easily.

[Structure of the idea]

The water heater of the present invention includes a cylindrical heat exchanger and a combustor in which a flame port is disposed in the heat exchanger. A pedestal having a bent piece is provided, and the combustor is fixed to the pedestal, and the combustor is inclined so that the front side of the combustor is lowered, and when the bent piece of the pedestal is placed, the combustor is fixed. A mounting table having a locking piece is provided at a position maintained substantially horizontally, a bent piece of the stand is placed on the locking piece of the mounting table, and the mounting table and the mounting table are screwed together. .

〔Example〕

Hereinafter, the water heater of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a sectional view showing an embodiment of the present invention, in which 1 is a flame port of a combustor, 2 is a heat exchanger, and 3 is an exterior body.

The flame opening part 1 of the combustor is arranged so that the flame opening is lower than the lower end part of the heat exchanger 2 so that the heat exchanger 2 can be heated efficiently, and the flame can be stably burned by preventing flame overflow and backfire. It is arranged so that the mouth part 1 faces upward.

A water pipe 4 is wound around the heat exchanger 2, and a vaporizer 5 is equipped with an electric heater on the primary air intake side of the flame port 1 of the combustor, and kerosene is supplied to the vaporizer 5. An electromagnetic pump 6 for supplying kerosene and an oil level regulator 7 for stably supplying kerosene to the electromagnetic pump 6 are provided.

According to the water heater of the present invention, the kerosene in the leveler 7 is sent to the vaporizer 5 by the electromagnetic pump 6, the kerosene is heated and vaporized by the electric heater of the vaporizer 5, and the vaporized gas is transferred to the combustor. The water in the water circuit is heated through the heat exchanger 2 by burning it at the flame port 1 of the flame port 1 .

Next, the mounting structure of the combustor will be explained.

FIG. 2 is an exploded perspective view of a pedestal 8 for attaching the flame port 1 of the combustor and the vaporizer 5, and a mounting table 9 for removably fixing the pedestal 8.

The pedestal 8 is formed into a flat plate shape, and has a bent piece 8a bent at a substantially right angle at one end thereof, and two recesses 8b for positioning at the other end. It is formed. Two screw holes 8c are formed in this bent piece 8a.

Furthermore, two mounting tables 9 are provided on the bottom plate 3a of the exterior body 3. This mounting table 9 has a front leg part 9a and a rear leg part 9b, and is formed to be inclined so that the front side faces downward as a whole. The front leg portion 9a of this mounting table 9 has a locking piece 9 cut and raised.
c and a screw hole 9b are respectively formed.

Then, as shown in FIG. 3a, the rear end of the pedestal 8 to which the combustor is attached is placed on the pedestal 9, and the bent piece 8a of the pedestal 8 is inserted into the locking piece 9c of the pedestal 9. By placing the heat exchanger on the heat exchanger and fixing it with screws, the flame port 1 of the combustor is positioned above the lower end of the heat exchanger 2 and fixed.

Next, when removing the combustor, as shown in FIG. The combustor and the pedestal 8 are removed from the mounting table 9 by sliding and pulling the pedestal 8 toward the front side.

In this case, when the bent piece 8a of the pedestal 8 is removed from the locking piece 9c of the mounting table 9, the front side of the pedestal 8 will fall downward, so that the flame opening 1 of the combustor can be connected to the heat exchanger 2.
It can be taken out without colliding with the object.

Incidentally, in the above embodiment, a combustor in which the flame port 1 and the carburetor 5 of the combustor are fixed to the pedestal 8 has been described, but the electromagnetic pump 6 and the oil level regulator 7 may also be mounted on the pedestal 8. In this case, even if the electromagnetic pump 6 or the oil level regulator 7 becomes clogged or otherwise malfunctions, the electromagnetic pump 6 or the oil level regulator 7 can be easily removed. Maintenance is also easier.

Further, the combustor may be fixed to the pedestal 8 by screwing, caulking, welding, or the like.

The present invention is not limited to the above embodiments, but can be applied to all types of combustors, such as pot-type combustors, rotary-type combustors, and even pressure-spray combustors. Within range.

[Effect of idea]

As detailed above, according to the water heater of the present invention, the water heater includes a cylindrical heat exchanger and a combustor in which a flame port is disposed within the heat exchanger. A pedestal having a bent piece bent downward is provided on the front side of the combustor, the combustor is fixed to the pedestal, the combustor is inclined so that the front side of the combustor is lower, and the bent piece of the pedestal is mounted. A mounting table having a locking piece is provided at a position where the combustor is maintained substantially horizontally when placed, and a bent piece of the stand is placed on the locking piece of the mounting table. Since the combustor is fixed with screws, if the bent piece of the frame to which the combustor is fixed is not placed on the locking piece of the mounting table, the flame opening of the combustor will be below the heat exchanger, and the combustor will The combustor can be removed, and when fixing the combustor, the bent piece of the pedestal can be screwed while remaining on the locking piece of the mounting base, making it extremely easy to install and remove the combustor. It becomes easier to maintain the equipment.
