Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boiler used mainly as a heat source for a heating water heater used at home.

[0002]

2. Description of the Related Art Conventionally, as a boiler of this type, a horizontal type can body having a boiler water storage section between the inner and outer cylinders and a boiler section inside the inner cylinder, has an exhaust outlet and hot water at the top of the can body. Those provided with a tube are known. In this type of boiler, when the air sent at the time of water supply or the air contained in the water used as the heat medium separates and collects in the boiler water storage part, a boiling noise is generated due to this. Further, since the air reservoir portion is concentrated and overheated, there is a problem that the durability of the can body in the air reservoir portion deteriorates. Therefore, conventionally, a hot water outlet pipe is provided at the top of the can body so that the air can be discharged through the hot water outlet pipe.

[0003]

However, in the case of providing the exhaust outlet of the can body, since the upper portion of the boiler water storage section is divided into left and right at the exhaust outlet, the air on the side where the hot water outlet pipe is provided is There is a problem that air can be discharged through the pipe, but the air on the opposite side cannot be wiped out.

It is an object of the present invention to obtain a boiler that eliminates the above problems.

[0005]

In order to achieve the above object, the present invention provides a horizontal type can body having a boiler water storage section between the inner and outer cylinders and a boiler section inside the inner cylinder. In a boiler provided with an exhaust outlet at the top, a hot water outlet pipe is provided at one side of the can body sandwiching the exhaust outlet, and an air vent pipe is provided at the other side.

[0006]

In the boiler having the above structure, the air accumulated in the upper part of the boiler water storage portion is discharged to the outside through the hot water discharge pipe and the air discharge pipe.

[0007]

Embodiments of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a boiler. The boiler 1 has a boiler water storage portion 2c between the inner and outer cylinders 2a and 2b in which both ends of inner and outer double cylindrical cylinders 2a and 2b are joined by seam welding or other means.
In addition, the inner cylinder 2a consists of a horizontal type can body 2 having a boiler part 2d, an exhaust outlet 3 is provided at the top of the can body 2, and the boiler part 2d is provided with an opening 2e at one end and the other end, The burner 4 is configured to face the inside of the boiler portion 2d through the opening 2e. 2f indicates a cover lid that closes the opening 2e.

Reference numeral 5 denotes a hot water outlet pipe provided at the top of one side of the can body 2 with the exhaust outlet 3 interposed therebetween, and 6 denotes an air vent pipe provided at the top of the other side of the can body 2 sandwiching the exhaust outlet 3. Then, the boiler 1 is installed horizontally with a side where the air vent pipe 6 is provided slightly higher in the substantially center of a rectangular casing 7, and its exhaust gas passes through an exhaust casing 8 provided in the upper part of the casing 7. The gas is discharged to the outside of the room through an exhaust stack (not shown) standing upright from the upper part of the housing 7 and a supply / exhaust top (not shown). Inside the exhaust casing 8, there is provided a heat exchanger 9 connected to the hot water discharge pipe 5 provided at the top of one side of the boiler water storage unit 2c.

The hot water heated in the boiler water storage section 2c is further heated by the heat exchanger 9 and then passes through a water tank 10 provided in the casing 7 through a water inlet 11 to a radiator for floor heating. 1
After being sent to No. 2, it returns to the boiler water storage section 2c via the return port 13.

The water tank 10 is provided with a lid 10a having an adjusting function of adjusting the internal pressure. The water tank 10
Water mixed with an antifreeze liquid as a heat medium is connected to a pipe 14 connecting the water supply port 11 and the water supply port 11 with a boiler water storage unit 2c and a radiator 12.
A pump 15 for forced circulation is interposed between and. The other end of the air vent pipe 6 was connected to the water tank 10. The burner 4 includes a fuel injection nozzle 4b for injecting kerosene and other fuel facing the cylinder 4a, and an igniter 4c,
The fuel ejected from the fuel supply nozzle 4b is supplied from the blower 16 connected to the root of the cylinder 4a directly into the cylinder 4a as well as from the air chamber 4d surrounding the cylinder 4a to the periphery of the cylinder 4a. Combustion is performed by the secondary air supplied through the air holes 4a-1 provided, and the combustion air is generated by the boiler portion 2d.
Is supplied to. Reference numeral 4e indicates a pump interposed in the fuel supply passage 4f.

The one end of the boiler portion 2d is closed by a closing plate 2d-2 attached to the end of the inner cylinder 2a via a packing 2d-1 as shown in FIG. The heat insulating material 2d-3 made of ceramic fiber is attached to the inner surface of 2. This insulation 2d-3
Is consumed by being exposed to the high heat from the burner 4. When the degree of wear of the heat insulating material 2d-3 progresses, the amount of heat transferred to the closing plate 2d-2 increases. Therefore, it is necessary to know the degree of wear and the time to replace the heat insulating material 2d-3. Therefore, a mounting portion 2d-2a of the temperature detector 14 is provided by extending near the peripheral edge of the closing plate 2d-2, and the mounting portion 2d-
2a is provided with a temperature detector 17, and when the temperature detected by the temperature detector 17 reaches or exceeds a predetermined temperature, the burner 4 is stopped and an alarm lamp (not shown) is turned on, and the heat insulating material 2d- I made it so as to notify the consumption of 3.

Reference numeral 18 denotes a supply cylinder connected to the supply / exhaust top (not shown), reference numeral 19 denotes a connecting pipe made of a copper pipe for connecting the heat exchanger 9 and the water tank 10, and the connecting pipe 19
The copper plate 20 is welded or brazed to the outside of the
A thermistor 21 as a temperature detector is attached on the upper side by a crimping claw 22.
It is attached via a mounting member 22 which is crimped by a and 22a, and the thermistor 21 can detect the hot water temperature. Conventionally, since a hole is formed in the connecting pipe 19 and the temperature detecting portion at the tip of the thermistor is exposed to the inside of the connecting pipe 19 to measure the hot water discharge temperature, the work of forming the hole in the connecting pipe 19 and the water from the hole are measured. There is troublesome work to prevent leaks. On the other hand, when the thermistor 21 is mounted as described above, the thermistor 21 can be easily mounted without any troublesome work.

Reference numeral 23 is a drain pipe for discharging overflow water of the water tank 10 through the lid 10a when the internal pressure of the water tank 10 is increased, 24 is a water level detector for detecting the water level of the water tank 10, and 25 is a boiler 1 Is a mounting metal fitting for mounting the housing 7 on the housing 7, and 26 is a control valve provided on the connection pipe 19 for adjusting the amount of hot water discharged. The control valve 27 supplies the amount of hot water discharged corresponding to the number of radiators 12 to the radiator 12 side. I did it.

[0014]

According to the present invention, the air accumulated in the upper portion of the boiler water storage portion is discharged to the outside through the hot water discharge pipe and the air bleeding pipe, so that air is accumulated in the upper portion of the boiler water storage portion. Can be resolved.
