Abstract

PROBLEM TO BE SOLVED: To obtain a bathroom heating system in which a temperature rise in bathroom is prevented and cool air can be supplied by switching the channel to a bypass circuit supplying no hot water to a radiator when heating is stopped. SOLUTION: A radiator 16 is set in the way of a supply circulation circuit 11 and extra firing and heating are operated simultaneously through the radiator 16. Water in a bathtub 15 is heated in a heat exchanger 2 by means of a burner 3 and returned back to the bathtub 15 after radiating heat partially through the radiator 16. A passage for closing a three-way valve 14 on the radiator 16 side and opening it on the bathtub 15 side and the supply circulation circuit 11 when extra firing operation is performed independent not through the radiator 16 is referred to extra firing independent circuit (bypass circuit). A circulation pump 9 circulates water in the passage in the same direction as described above and returns the water back to the bathtub 15 after heating it in the heat exchanger 2 by means of the burner 3. When cool air is produced, a heat radiating fan 12 is operated by the extra firing independent circuit (bypass circuit).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water heater for additionally heating the inside of a bathtub with a circulation circuit connecting a water heater and a bathtub, and a radiator for blowing hot air to heat the bathroom in the middle of the circulation circuit. The present invention relates to a heating system provided with a heating device.

[0002]

2. Description of the Related Art Conventionally, there has been a bathroom heating system in which air in a bathroom is circulated to perform heating, and when the heating is stopped, a fan of a blower is stopped.

[0003]

In a conventional bathroom heating system, when heating is stopped, heating is stopped by stopping a fan of a blower. Hot water flows into the bathtub even when the ventilation is stopped, and hot water flows into the radiator during additional heating. Hot air is not generated due to the stoppage of the air supply, but heat exchange in the radiator is performed and the temperature in the bathroom may increase.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a radiator that does not perform heat exchange when heating is not required, thereby increasing the temperature in a bathroom. Another object of the present invention is to provide a bathroom heating system capable of blowing air and blowing cool air.

[0005]

Means for Solving the Problems and Their Functions and Effects To achieve the above object, a first aspect of the present invention is a water heater that reheats the inside of a bathtub by a circulation circuit connecting the water heater and the bathtub, On the way, in a heating system in which a radiator that blows warm air to heat the bathroom is installed, when the heating is stopped, the temperature in the bathroom rises by switching the flow path to a bypass circuit that does not supply hot water to the radiator. Can be eliminated.

According to a second aspect of the present invention, the bypass circuit is provided with a three-way valve between the circulation circuit and the radiator, so that the bypass circuit can be switched by opening and closing the switching valve.

According to a third aspect of the present invention, by switching the flow path to a bypass circuit that does not supply hot water to the radiator and then blowing air, cool air can be sent into the bathroom.

[0008]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram of the entire heating system, in which a radiator 16 is installed in the middle of the circulation circuit 11. A simultaneous circuit for simultaneously operating additional heating and heating via the radiator 16 will be described. A path in which the radiator 16 side of the three-way valve 14 and the going circulation circuit 11 side are opened is called a simultaneous circuit. The circulation pump 9 is a return circulation circuit 1 for the bathtub 15.
0, and circulates in a direction passing through the heat exchanger 2 and the going circulation circuit 11. After the water in the bathtub 15 is heated by the burner 3 in the heat exchanger 2, a part of the water is radiated by the radiator 16, and
Return to Heating is performed by the heat radiation of the radiator 16 at this time, and additional heating is performed by the remaining heat.

Next, a description will be given of a reheating independent circuit for performing the reheating independent operation without passing through the radiator 16. Three-way valve 14
The radiator 16 side is closed and the bathtub 15 side is closed and the circulation circuit 11 is closed.
The path whose side is opened is called a reheating independent circuit (bypass circuit). The circulation pump 9 circulates the water in the path in the same direction as described above, and is returned to the bathtub 15 after being heated by the burner 3 in the heat exchanger 2. When cool air is to be obtained, the heat-dissipating blower 12 is operated in this additional circuit (bypass circuit).
