Description

[Detailed description of the invention] [Industrial application field] The present invention is a hot water supply system that is equipped with a bath pot and an oil water heater. This invention relates to an exhaust structure that incorporates a muffler into a road.

[Conventional technology]

Conventionally, this type of hot water supply equipment, as shown in FIGS. 5 and 6, has a bathtub 2 and an oil water heater 3 installed on a base 1, and a housing 4 that constitutes the oil water heater 3.
A muffler 5 is built in, and an exhaust gas path 5a of the muffler 5 and an exhaust gas path 6 extending from the bathtub 2 are assembled. The bathtub 2 is provided with a burner 7, and the oil water heater 3 is provided with a burner 8.

[The problem that the idea aims to solve]

However, conventional hot water supply equipment has the following problems.

(a) Since the silencer 5 is built into the casing 4 that constitutes the oil water heater 3, the heat exchange heat transfer area of the casing 4 cannot be increased, and the water and combustion gas inside the casing 4 cannot be increased. The heat exchange efficiency was low.

(b) Also, since it is a type with a built-in silencer 5,
Attempting to secure a certain heat transfer area had the drawback of increasing the size of the entire facility.

(c) Because the exhaust gas path 6 extending from the bathtub 2 was not connected to a silencer, the combustion sound of the burner 7 leaked outside, causing noise.

[Means to solve the problem]

The present invention has been developed to improve and eliminate the above-mentioned problems of the conventional technology.It has a sound-absorbing structure, makes hot water supply equipment more compact, improves heat exchange efficiency, and achieves stable combustion. That is.

Therefore, the means adopted by the present invention to solve the above problem is to arrange the bath kettle and the oil water heater diagonally on a rectangular base, so that the bath kettle and the oil water heater are arranged diagonally on a rectangular base. A muffler with a collective exhaust pipe housed in the outer shell is disposed above the bathtub, and a lower end opening of the collective exhaust pipe is communicated with the inside of the outer shell, and The upper end opening of the collective exhaust pipe is communicated with the outside of the outer shell, and the exhaust gas path of the kerosene water heater is communicated with the upper part of the guide path formed between the outer shell and the collective exhaust pipe, so that the exhaust gas of the bathtub is communicated with the outside of the outer shell. The passage is introduced into the inside of the collective exhaust pipe from the lower end opening and communicated upward, and a passage communicating with the oil water heater exhaust gas passage is formed between the bathtub exhaust gas passage and the collective exhaust pipe. .

[Effect]

The exhaust gas discharged from the oil water heater is guided to the guide path in the silencer via the oil water heater exhaust gas path.
It passes through the collective exhaust stack and is exhausted to the outside. Also,
Exhaust gas discharged from the bathtub is guided to the lower end opening of the collective exhaust stack through the bathtub exhaust gas path, passes through the collective exhaust stack, and is discharged to the outside. When both the kerosene water heater and the bathtub are operating, a large amount of exhaust gas discharged from the kerosene water heater creates a negative pressure inside the collective exhaust stack as it rises up the collective exhaust stack. Exhaust gas in the bathtub exhaust gas path is forcibly sucked into the cylinder.

〔Example〕

The following is a hot water supply facility that is equipped with a bath pot and an oil water heater according to the present invention (hereinafter referred to as the "proposed facility").
The following is an explanation based on the embodiment shown in FIGS. 1 to 4.

Figure 1 is a front view with a cross section of the main parts of the proposed equipment, Figure 2 is a right side view with a part of the proposed equipment in section, and Figure 3
The figure is a plan sectional view of the proposed equipment, and FIG. 4 is a vertical sectional view of the silencer.

The proposed equipment 10 has a vertically cylindrical oil water heater 13 and a box-shaped bathtub 12 installed on a base 11. The arrangement relationship between the oil water heater 13 and the bath pot 12 is as shown in FIG. Bath pot 1 near the inner corner
2 is installed to form an area A on the base into which the oil water heater 13 and the bath pot 12 enter alternately. By forming the entry area A in this way, it becomes possible to reduce the depth dimension L of the base 11, and the proposed equipment 10 can be made compact.

As shown in FIG. 1, the oil water heater 13 has a combustion chamber 14a formed in the lower half thereof, and a
4a, and a combustion chamber 14.
It consists of a burner 17 installed facing toward a. The upper surface of the housing 14 where the discharge ports of the smoke pipes 14b, 14b, . . . are opened is covered with an oil water heater exhaust gas passage 19 (see FIG. 4). After the combustion gas of the burner 17 is diffused in the combustion chamber 14a, it passes through the smoke pipe 14b,
14b... becomes exhaust gas, and is led to the oil water heater exhaust gas path 19. Water supplied to the housing water chamber 14c from the water supply pipe 21 of the housing 14 exchanges heat with the combustion gas, heats up, and is discharged from the hot water outlet pipe 22 (see FIG. 3).

On the other hand, the bathtub 12 includes a combustion chamber 23, a heat exchanger 24 (see FIG. 2) installed in the combustion chamber 23, and a burner 1 installed facing the combustion chamber 23.
8 and more. The combustion gas of the burner 18 is diffused in the combustion chamber 23, and after exchanging heat with the water in the bathtub circulating in the heat exchanger 24 through the circulation channels 25 and 26 (see FIG. 2), the combustion gas is passed through the bathtub exhaust gas channel 20. be led to. Fans 27 and 28 for blowing combustion air to the burners 17 and 18 are disposed at a height between the bathtub 12 and a silencer 15, which will be described later, and are driven by a single motor 29.

A muffler 15 is disposed above the bathtub 12. The silencer 15 is as shown in FIG.
A collective exhaust pipe 16 is built inside the outer shell 31, forming a terminal area of the guideway 32 in the lower part of the inside of the outer shell and facing the lower end opening 16a of the collective exhaust pipe 16. 16 upper end opening 16
b is shown. In the outer shell 31, a sound absorbing material 31b made of glass wool or the like is filled between an exterior plate 31a and a porous interior plate 31c. The silencer 15 is located above the guideway 32 formed between the outer shell 31 and the collective exhaust stack 16, and the oil water heater exhaust gas passage 1 is formed integrally with or separately from the outer shell 31.
9, and insert the end of the bathtub exhaust gas path 20 into the lower end opening of the collective exhaust pipe 16 with the end facing upward, or insert the end of the bathtub exhaust gas path 20 in the vicinity of the lower end opening. It is facing upwards. In this state, an annular passage communicating with the guide passage 32 is formed between the collective exhaust pipe 16 and the bathtub exhaust gas passage 20.

The oil water heater exhaust gas a supplied from the oil water heater exhaust gas path 19 to the muffler 15 flows downward through the guide path 32 to the lower end opening 16a of the collective exhaust pipe 16.
and ascend inside it. The bathtub exhaust gas b supplied to the muffler 15 from the bathtub exhaust gas path 20 is guided into the lower end of the collective exhaust pipe 16 and rises therein. When the oil water heater exhaust gas a and the bathtub exhaust gas b are simultaneously led to the silencer 15, the oil water heater exhaust gas a is directed to the common exhaust stack 1.
6, the inside of the collective exhaust pipe 16 is brought into a negative pressure state, so that the bathtub exhaust gas b is forcibly sucked into the collective exhaust pipe 16 and is discharged to the outside as the collective exhaust gas c.

[Effect of idea]

As detailed above, the proposed equipment has the following practical effects.

Oil water heaters do not need a built-in silencer, so it is possible to increase the heat exchange heat transfer area by installing smoke pipes etc. inside the casing that makes up the oil water heater. It becomes possible to improve exchange efficiency.

A silencer is installed above the bathtub.
Since the exhaust gas is guided to this muffler, the combustion noise of the bathtub burner is reduced, making it possible to provide a low-noise hot water supply facility.

The arrangement of the silencer makes effective use of the wasted space above the bathtub, and the bathtub and kerosene water heater are placed diagonally on the base, forming a mutually intersecting area. It becomes possible to make the entire equipment compact.

When both the oil water heater and the bath kettle are operating, the oil water heater exhaust gas is forcibly sucked in from the bath kettle exhaust gas in the collective exhaust stack and is discharged to the outside as a collective exhaust gas. As a result, the oil water heater exhaust gas does not flow back into the bath pot, and stable combustion in the oil water heater and bath pot is maintained.
