[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a boiler for heating a heat medium circulating between a heat medium liquid tank and an external radiator such as a snow melting machine or a floor panel for heating.

[0002]

2. Description of the Related Art Conventionally, a burner device for heating a heat medium in a tank and a pump for circulating the heat medium between the tank and an external radiator such as a snow melting device or a floor heater are provided. Boilers are known.

[0003]

However, as shown in FIG. 6, this type of boiler has a construction in which a header c for connecting a tank a and a plurality of external radiators b is separately provided outside the tank a. In addition to the work of connecting the header c to the tank a on site, there is a problem that a place for installing the header c is required. The purpose of the present invention is to obtain a boiler free of such defects.

[0004]

According to the present invention, in order to achieve the above object, a burner device for heating a heating medium in a tank and a heating medium circulating between the tank and an external radiator are provided. In a boiler provided with a pump, the suction port of the pump is opened below the liquid surface of the heat transfer fluid in the tank, and a discharge header connected to the discharge port of the pump is installed in the tank and provided in the discharge header. Further, a connection port for connecting to each radiator is provided on the tank wall, and a connection port for the heat transfer medium returning from each radiator to the tank is provided on the tank wall.

[0005]

In the boiler having the above configuration, the discharge header is provided in the tank, so that not only the work of mounting the discharge header at the construction site is not required, but also the connection port for each radiator provided in the header is provided. Since the connection ports for the heat transfer medium returning from the radiators to the tank are provided on the tank walls, the installation work is completed only by connecting the connection pipes connected to the radiators to the connection ports.

An embodiment of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes a tank, and 2 denotes a burner device for heating the heat transfer fluid in the tank 1 provided adjacent to the tank 1. The burner device 2 supplies kerosene from a nozzle 2a to a combustion chamber 2b. A gun-type burner that is jetted toward the same direction and is stirred and mixed with the fuel and air sent from the blower 2c by a stabilizer 2d and then burns in a combustion chamber 2b.
e was exposed to the inside of the tank 1 to heat the heat transfer medium in the tank 1.

FIG. 3 shows a pump 3 for circulating between the tank 1 and each radiator 4. The pump 3 is provided in a case 5 in which a burner device 2 is stored.
A suction port 3a is opened near the liquid surface of the tank 1 and a box-shaped discharge header 6 connected to the discharge port 3b of the pump 3.
Is provided in the tank 1 near the bottom of the tank 1, and each connection port 7 of the discharge header 6 is made to protrude outside in a horizontal line through a side wall of the tank 1, and a return passage of each radiator 4 is provided. The connection ports 8 communicating with each other were provided on the side wall of the tank 1 so as to correspond to the connection ports 8.

In FIG. 1, reference numeral 9 denotes an intake / exhaust tube connected to the intake port of the blower 2c and the exhaust tube 2e, 10 denotes a liquid level detector incorporating a reed switch for monitoring the liquid level position of the tank 1, 1
Reference numeral 1 denotes a lid provided on the tank 1. The supply of the heat medium to the tank 1 is performed by removing the lid 11. 12 is the lid 11
, A connection pipe for connecting the connection port 7 and the connection port 8 to the radiator 4, and an opening / closing stopper 14 provided at the entrance and exit of the pump 3.

In the above embodiment, the connection port 7 and the connection port 8 are provided so as to protrude outward from the side wall of the tank 1.
This need not necessarily be projected from the side wall of the tank 1. This embodiment will be described with reference to FIGS. 4 and 5.
The connection port 7 is formed by screwing a short pipe made of a threaded pipe 7b having a flange 7a at the outer end on the outer side wall of the box-shaped discharge header 6 connected to the discharge port 3b of the pump 3. 8
Similarly, if a short pipe made of a screw pipe having a flange at the outer end is screwed to the side wall of the tank 1, the connection port 7 and the connection port 8 are provided without protruding outside.

Incidentally, it is needless to say that the unused connection ports 7 and 8 are provided with blind plugs as appropriate.

[0012]

[Effect of the Invention] In the boiler having the above configuration,
The suction port of the pump is opened below the liquid level of the heat transfer fluid in the tank, and a discharge header connected to the discharge port of the pump is installed in the tank, and a connection port for each radiator provided in the discharge header is provided. Since the connection port for the heat transfer liquid returning to the tank from each radiator is provided on the tank wall and provided on the tank wall, not only the work of mounting the discharge header at the installation site as in the conventional example is not necessary, but also The connection port for each radiator provided on the header is projected from the tank wall to the outside, and the connection port for the heat transfer liquid returning from each radiator to the tank is provided on the tank wall. The installation operation is completed simply by connecting the connecting pipes connected to the vessel, and the installation operation is simplified, and there is no need to provide a separate space for mounting the discharge header.
