Is placed. The oil tank 15 is set to have an oil storage amount of about 15 to 25 liters. The oil stored in the oil tank 15 is pumped up by a fuel pump 18 such as an electromagnetic pump, and a fuel supply pipe 19. To the oil burner 8.
[0011]
The oil burner 8 is a rotary gasification burner with variable combustion amount that vaporizes and burns kerosene, and the heat generation amount can be varied in the range of about 1,200 to 3,000 kcal / h according to the heat demand of the equipment. it can. The instantaneous heat exchanger 9 heated by the oil burner 8 is connected at its base to the tip of the oil burner 8, and at its tip is provided with an exhaust box 9A. The exhaust gas in 9 </ b> A is released from the exhaust top 21 through the exhaust pipe 20.
[0012]
The connecting structure X between the oil burner 8 and the instantaneous heat exchanger 9 is installed horizontally in the upper space in the casing 1 immediately above the oil tank 15, and the connecting structure X installed horizontally is An appropriate position of the oil burner 8 on one end side is fixed and held by a fixing plate device 22 to be described later, and an exhaust box 9A on the other end side is placed on one upper side in the casing 1 via a locking fitting (not shown). The support plate 23 is attached and held. A blower 24 supplies combustion air to the oil burner 8, and the blower 24 is connected to the oil burner 8.
[0013]
The fixing plate device 22 has a lower edge portion fixed to a fixing fitting 25 mounted on the upper surface of the oil tank 15 by screws or the like, and a rear edge portion fixed to the back plate 6 of the casing 1 by screws or the like. The main fixing plate 22A provided with a front opening notch for inserting the oil burner 8, and the oil burner 8 inserted in the notch of the main fixing plate 22A, and then screwed to the main fixing plate 22A from the front. It is composed of a detachable auxiliary fixing plate 22B.
[0014]
26 is a replenishing port lid of the cistern tank 10, 27 is a control box, 28 is a return side connection port, and the warm water after radiating heat from the floor heating panel 11 returned from the return side connection port 28 to the heat source unit A is returned. The hot water that has flowed to the instantaneous heat exchanger 9 through the pipe 29 and heated there to rise in temperature enters the cistern tank 10 through the first outgoing pipe 30, and the hot water in the cistern tank 10 is second It enters the circulation pump 12 through the outgoing pipe 31, where it is pressurized and flows to the outgoing side connection port 33 through the third outgoing pipe 32.
[0015]
FIG. 4 is an explanatory diagram of the installation state of the entire hot water heating system using the heat source unit A according to the present invention, and the hot water from the heat source unit A installed outdoors passes through the piping 34 for the outdoor side and enters the room wall 35. It flows to the floor heating panel 11 laid on the indoor floor 39 through the provided outlet 36, plug 37 and indoor-facing piping 38, and after radiating heat , the indoor-side return piping 40, plug 37, outlet 36 and roof It returns to the heat source machine A again through the outer return pipe 41.
[0016]
According to this embodiment, the oil burner 8, the instantaneous heat exchanger 9 connected to the oil burner 8, the cistern tank 10 for storing hot water heated by the instantaneous heat exchanger 9, There is a circulation pump 12 that circulates hot water of the cistern tank 10 to the floor heating panel 11, an oil supply port 13, and an oil amount indicator 14, and an oil storage amount for storing oil supplied to the oil burner 8 by using the fuel pump 18 is A fixed oil tank 15 of 15 liters to 25 liters is accommodated in one casing 1, and the opening / closing lid 16 provided on the front panel 7 is opened so that the oil tank 15 can be easily inserted into the oil tank 15. Since the oil can be replenished, it is not necessary to prepare and install an oil tank installed outside the heat source machine A, and it is also necessary to secure an installation space for the oil tank separately from the heat source machine A Absent. Therefore, not only installation in a narrow installation space such as a veranda becomes possible, but also installation time can be shortened and installation work can be simplified.
[0017]
Further, the oil tank 15 is fixedly placed on the bottom plate 3 of the casing 1, and the connecting structure X of the oil burner 8 and the instantaneous heat exchanger 9 is installed horizontally in the casing 1 above the oil tank 15. Therefore, the oil tank 15 is located below the oil burner 8 and the instantaneous heat exchanger 9 so that the oil tank 15 is not easily affected by the heat radiation of the oil burner 8 and the heat radiation from the oil burner 8 and the instantaneous heat exchanger 9. Is released to the outside without stagnation from the vent part c in the upper part of the casing 1 by the flow of fresh air flowing in from the vent parts i and b in the lower part of the casing 1, so that the temperature rise of the oil tank 15 can be suppressed. Further, the connection structure X between the oil burner 8 and the instantaneous heat exchanger 9 has a configuration in which an appropriate position of the oil burner 8 on one end side is fixed and held by a fixing plate device 22 erected on the oil tank 15. Therefore, the oil tank 15 can be used as a support member for the connection structure X. Furthermore, since the circulation pump 12 is arranged side by side on the oil tank 15 and fixedly mounted on the bottom plate 3 of the casing 1, the weight of the circulation pump 12 and the oil tank 15 acts to stabilize the casing. However, although the connecting structure X of the oil burner 8 and the instantaneous heat exchanger 9 is installed in the casing 1 above the oil tank 15, the casing can be stably installed.
[0018]
【The invention's effect】
In the heat source heater for hot water heating according to claim 1, an oil burner, an instantaneous heat exchanger connected to the oil burner, a hot water tank for storing hot water heated by the instantaneous heat exchanger, Since the circulation pump that circulates the hot water of the hot water tank to the external radiator and the oil tank that has an oil supply port and stores oil supplied to the oil burner are accommodated in a single casing, A separate oil tank is not required, installation is possible even in a narrow installation space, and installation time can be shortened and installation work can be simplified.
[0019]
The oil tank is fixedly mounted on the bottom plate of the casing, while the connecting structure of the oil burner and the instantaneous heat exchanger is installed horizontally in the casing above the oil tank, and this horizontally installed connection Since the structure has a structure in which at least one end side is fixed and held by a fixed plate device standing on the oil tank, the oil tank can be made less susceptible to the thermal effects of the oil burner and the instantaneous heat exchanger. In addition, the oil tank temperature can be suppressed and safety can be maintained, and the oil tank can be used as a support member for the oil burner and the instantaneous heat exchanger. A sufficient installation space can be secured, and an oil tank with a large oil storage capacity can be accommodated.
