Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat source machine that exhibits three functions of hot water supply, heating, and bath heating by itself.

[0002]

2. Description of the Related Art FIG. 4 shows the structure of a heat source machine for hot water supply, heating, and bath reheating by itself. In FIG. 4, 100 is an exterior, 101 is a heat exchanger for hot water supply, 102 is a gas burner,
103 is a heat exchanger for heating, 104 is a gas burner, 105
Is a heat exchanger for reheating, 106 is a forward header for heating,
Reference numeral 107 is a heating return header, 108 is a bathtub, 109 is a water supply line, 110 is a hot water supply line, 111 is a circulation pump, 112 is a hot water filling line, 113 is a reheating line, 114 is a reheating return line, and 115 is a circulation pump. And has the following functions.

A. Hot water supply Heat exchanger 1 for supplying hot water from the water supply line 109
01 is heated and hot water is supplied from the hot water supply line 110 to the hot water tap (not shown) side.

B. Heating Circulating pump 11 for hot water heated by heat exchanger 103 for heating
1 sends from the heating outward header 106 to a radiator (not shown) in each room, and the hot water returned from the radiator is returned from the heating return header 107 to the heating heat exchanger 103,
Reheat and send to the radiator side.

C. Bath hot water supply (filling with water) and reheating When the bathtub 108 is filled with hot water, the heat exchanger 10 for hot water supply is used.
The hot water heated in 1 is sent from the hot water filling line 112 to the inside of the bathtub 108 via the reheating line 113. In the reheating, the hot water heated by the heating heat exchanger 103 is circulated in the reheating heat exchanger 105, and at the same time, the heat is applied to the bathtub 108, the reheating line 114, and the circulation pump 115.
→ Additional heating heat exchanger 105 → Additional heating line 113
The hot water circulating in the bath 108 is heated via However, when heating is being performed simultaneously, the hot water that has passed through the reheating heat exchanger 105 directly goes to the heating forward header 106 side. In addition, the cistern attached to the heating circuit is omitted in the figure.

[0006]

However, the above conventional heat source machine has the following drawbacks.

A. Since the conditions for hot water supply, heating, and reheating are different depending on the number of rooms in the home to be installed, the number of people, etc., it is necessary to prepare a large number of combinations with different capacities, and the number of models of heat source machines increases. Therefore, the manufacturing cost is high.

B. If you want to increase only the heating capacity or hot water supply capacity after installing once, it is not possible to deal with each individually, so one heat source machine must be replaced entirely.

C. In the event of a catastrophic failure that cannot be repaired, one heat source unit must be replaced entirely.

An object of the present invention is to propose a heat source machine for hot water supply, heating, and bath reheating which does not have the drawbacks described in the above a to c.
