Abstract

PURPOSE:To enable a hot water heating source machine to be accommodated for the case in which there are provided a larger number of terminal heat radiation machines than the number specified by a standard specification. CONSTITUTION:There is provided a valve 23 to be opened or closed with a starting or stopping signal obtained from a heat radiation machine 10 at a hot water feeding connector 22 within a hot water heating source machine 21. There are also provided a connection port 34 of standard specification having this valve 23 and a control part 5 connected in advance from each other and a connection port 35 to be incremented for use in connecting to the heat radiating machine 10 having the larger number of pipes than that of standard specification.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water heating heat source device for supplying hot water of a heating system which conveys hot water and causes a radiator of a terminal to generate hot air.

[0002]

2. Description of the Related Art In recent years, there has been a demand for a hot water heating heat source device of a construction-saving type that does not require any labor due to lack of manpower of a contractor. Also, depending on the installation location of the hot water heating heat source device, for example, in the pipe shaft, A
Explosion-proof treatment is required for C100V wiring.

FIG. 2 shows an explanatory diagram of the configuration of a conventional hot water heating system. In the figure, reference numeral 1 is a hot water heating heat source machine, which is provided with a hot water expansion tank 2; a hot water circulation pump 3; a hot water heating unit 4; a controller 5; a hot water outgoing connection 6; and a hot water return connection 7 ing. The hot water outgoing connection unit 6 is connected to a thermal valve 8 having a valve that opens and closes in response to a start / stop signal from the terminal device, and connects the control unit 5 of the hot water heating heat source device and AC100V. At this time, explosion-proof treatment is performed if necessary. Reference numeral 9 is a pipe for carrying hot water, 10 is a heat radiator of a terminal, and 11 is a signal line for transmitting an on / off signal from the terminal.

[0004]

However, in the above-mentioned configuration, the contractor prepares and installs the heat-operated valve, and the heat-operated valve, the control unit of the hot water heating heat source unit, and the AC10.
It took a lot of time and effort to construct it, such as connecting it to 0 V and performing explosion-proof treatment if necessary.

Therefore, an object of the present invention is to provide a hot water heating heat source machine of a construction-saving type that requires no troublesome construction, and at the same time, to provide a hot water heating heat source machine which can cope with a large number of terminal radiators. With the goal.

[0006]

In order to achieve the above object, the hot water heating heat source device of the present invention is provided with a standard specification connection port having a valve that opens and closes at a hot water outgoing connection part by a start / stop signal from a terminal device. , With a connection port for expansion.

[0007]

According to the above means, the present invention provides a thermal valve having a valve that is opened / closed by a contractor when a number of installed terminals is equal to or less than the standard specification number by a start / stop signal from the terminal.
It is possible to install it, connect the control part of the hot water valve and the hot water heating heat source machine to AC100V, and make the explosion proof treatment if necessary. If you have a radiator, you can use the conventional connection method by utilizing the connection port for expansion.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments will be described below with reference to the drawings. FIG. 1 is a configuration diagram of a hot water heating system of the present invention. In FIG. 1, reference numeral 21 denotes a hot water heating heat source device, 2 hot water expansion tanks, 3 hot water circulation pumps, 4 hot water heating units,
It is provided with a control unit 5; a hot water outgoing connection unit 22; and a hot water return connection unit 7. The hot water outgoing connection part 22 is provided with a standard specification connection port 34 that has three valves 23 that open and close in response to a start / stop signal from a terminal, and the valve 23 and the control part 5 are connected in advance by a wire 24. . Wiring 24 is AC100V
However, since it is inside the heating heat source machine, there is no need for explosion-proof treatment at any installation location. Considering the number of radiators at the terminals of a standard hot water heating system, the valve 23 is a triple valve.
If it is more than this, the number of use cases is small and the cost becomes high.

Reference numeral 35 denotes a connection port for expansion, and when the number of radiators of the terminal is 3 or more, a commercially available thermal valve 36 can be attached according to the number thereof by a conventional method. The expansion support connection port 35 is closed at the time of shipment from the factory with an expansion support connection port lid. The connection port lid for expansion is not shown. Reference numeral 9 is a pipe for carrying hot water, 10 is a heat radiator of a terminal, and 11 is a signal line for transmitting an on / off signal from the terminal.

[0010]

As described above, in the hot water heating heat source device of the present invention, when there is a terminal radiator having a standard specification or more, it can be dealt with by the conventional construction method using the connection port for expansion, and the standard specification In the following construction, the standard specification connection port can be used to improve the workability.
