Description

[Detailed Description of the Invention] The present invention uses solid fuel such as firewood and charcoal for combustion in addition to combustion using an oil or gas burner.

Such a boiler has a fire port and a burner port that communicate with the combustion chamber, and the fire port is provided with a lid having an air conditioning port on the outside of the firewood and charcoal guide tube. Therefore, when burning in a gas or oil burner from the burner port, the combustion gas comes into contact with the lid, and there is also air leakage from the air adjustment port, which cools the lid, preventing proper re-combustion and causing CO2 to evaporate. The disadvantage was that it frequently occurred. Furthermore, when fixed fuel is burned from the fire pit, if the smoke hole construction is insufficient or if the smoke hole is clogged, backfire may occur at the burner port.

The present invention has been developed in view of the above points, and an embodiment will be described below with reference to the drawings. 1 is an annular hot water storage tank surrounded by an inner can 2 and an outer can 3; 4 is a hot water storage tank formed inside the inner can; A full cylinder 5 is installed inside the combustion chamber,
A smoke hole 6 is also provided at the top. 7 is hot water tank 1
9 is a burner port that penetrates through the inner and outer cans 2, 3 and the outer case 7 and communicates with the combustion chamber 4, and the flame port 10' of the oil or gas burner 10 is Although it is inserted, it is attached so that the tip does not protrude into the combustion chamber 4. 11 is burner port 9
A firewood and charcoal guide tube 12 is provided at a firewood opening that is adjacent to and communicates with the combustion chamber 4, and solid fuel such as firewood and coal is introduced into the combustion chamber 4 through this firewood mouth 11 and a rostol 13 is provided.
is burned on top. Reference numeral 14 denotes a lid body provided on the outside of the firewood and charcoal guide tube 12 so as to be openable and closable, and an air conditioning opening 15 is provided therein. Reference numeral 16 denotes a water supply pipe that hangs down into the hot water storage tank 1 from above, and the supplied amount of hot water is pressed and taken out from the hot water outlet 17. 18 is the drain port, 19
20 is a thermal pressure valve that opens at abnormal hot water temperature, and 20 is a shielding lid that is slidably attached to the inner surface of the combustion chamber 4 in the left-right direction, and has a knob on the left end, and when the fire port 11 is blocked as shown in Fig. 2, it is closed to the burner port 9. is opened, and conversely, when the fire port is opened, the burner port 9 can be closed.

As described above, according to the present invention, the burner 10
When using the burner port 9, the combustion port 11 is inevitably closed by sliding the shielding lid 20 in the direction of opening the burner port 9, thereby improving the airtightness of the combustion chamber 4. In this state, the burner port 9 is closed. By combusting the combustion chamber 4, it is possible to achieve complete combustion without leaking combustion gas from the combustion port 11 or cooling the inside of the combustion chamber 4 due to the inflow of air.

In addition, when burning firewood and charcoal using the fire port 11, the burner port 9 is inevitably closed by sliding the shielding lid 20 in the direction of opening the fire port 11, so that the flame enters the burner port 9. Come in and burner 1
Even if the combustion chamber 4 is filled with smoke or the like due to heating or the smoke hole 6 is clogged, this smoke will not enter the burner port 9 and have no adverse effect on the burner 10.

Furthermore, by simply sliding the shielding lid 20 and selecting combustion using firewood and charcoal or the burner 10, it is possible to achieve the optimum state depending on the type of combustion.
