Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water heater.
More specifically, the present invention relates to a hot water heater having a cistern tank.

[0002]

2. Description of the Related Art Conventionally, as shown in the block diagram of FIG. 2, a conventional hot water heating device flows in a heat exchanger 2 heated by a heating device 1 such as gas or oil and is heated by heat exchange. Is stored in the cistern tank 3, and when the temperature of the hot water in the cistern tank 3 becomes almost uniform, the hot water is delivered from the hot water outlet at the bottom of the cistern tank 3 to the radiator 7 provided in the room by the circulation pump 6. The warm water that has exchanged heat with the air to warm the room and radiates heat circulates through the return pipe of the radiator 7 and returns to the heat exchanger 2 to heat the room. At the start of operation, the heat exchanger 2 is not sufficiently heated, the temperature of the hot water flowing is low, and the water in the cistern tank 3 cannot be sufficiently warmed. Could not be warmed, it took time for the indoor temperature to rise, and the heating device lacked quick heating. As an example, the capacity of the cistern tank 3 is about 3 liters, and it takes about 8 minutes until the hot water temperature required as a heat source of the radiator 7 reaches 80 ° C.

[0003]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems of the prior art, and at the same time as the start of operation, the hot water flowing through the heat exchanger is sent to the radiator as soon as possible to increase the room temperature. The purpose is to provide an accelerated hot water heating system.

[0004]

In order to achieve the above object, a partition is provided in the cistern tank so as to face the hot water inlet and stand upright from the bottom and divides the bottom into two parts. A hot water outlet and a second hot water outlet are provided at the bottom of the partition on the side opposite to the hot water inlet, and each hot water outlet is connected to a circulation pump via a first water flow control valve and a second water flow control valve. When the operation is started, the first water passage control valve is opened, the second water passage control valve is closed to circulate hot water, and when the hot water temperature reaches a predetermined temperature, the first water passage control valve is opened. Second closed
The water flow control valve was opened to circulate hot water.

[0005]

According to the above-mentioned structure, a partition partition is provided inside the cistern tank so as to face the hot water inlet from the bottom surface and divides the bottom portion into two parts.
The water flow control valve is closed, the inflowing hot water is retained at the hot water inlet side of the cistern tank, the temperature of the hot water in this part is raised quickly, and the first hot water outlet circulates through the first water control valve. By sending the heat to the radiator by the pump, the rise of the emission temperature of the radiator can be accelerated. When the hot water temperature of the cistern tank reaches a predetermined temperature, the first water flow control valve is closed, the second water flow control valve is opened, and hot water is supplied from the second hot water outlet to supply hot water to the cistern tank. The temperature can be made uniform and a stable operation of the hot water heater can be performed.

[0006]

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of the present invention. A heating device 1, a heat exchanger 2 for exchanging heat with water flowing in by the heating device 1 to produce hot water, a cistern tank 3 for storing hot water, and a cistern tank 3 A circulation pump 6 connected to a first hot water outlet 4 and a second hot water outlet 5 provided at the bottom of the unit for circulating hot water and a radiator 7 provided on the indoor side are sequentially connected by pipes to circulate hot water. The road is formed.
A temperature sensor 8 for detecting a hot water temperature is attached to a pipe extending from the heat exchanger 2 to the systern tank 3, detects the hot water temperature in the pipe and sends the temperature to the control unit 9, and the control unit 9 keeps the hot water temperature at a predetermined level. The operation of the heating device 1 is controlled so as to be maintained within the range. A partition 11 is formed inside the cistern tank 3 so as to project from the bottom and face the hot water inlet 10. The hot water that flows in is blocked by the partition 11 and does not freely diffuse in the cistern tank 3, and the hot water inlet side Stays in the cistern tank 3 and gradually diffuses due to convection.
I try to warm the water inside. When the operation of the hot water heating device is started, the heating device 1 is ignited by the control unit 9,
The heat exchanger 2 is heated to warm the water flowing in the heat exchanger 2,
It is sent to the hot water inlet 10 of the cistern tank 3 and the diffusion is blocked by the partition 11 in the cistern tank 3, and the temperature of the hot water in the cistern tank 3 is higher on the hot water inlet side than on the partition 11 and lower on the anti-hot water inlet side. Has become. In this state, the first water flow control valve 12 connected to the first hot water outlet 4 is opened, the second water flow control valve 13 connected to the second hot water outlet 5 is closed, and hot water is circulated. Then, the high temperature hot water on the hot water inlet side is sent to the radiator 7 on the indoor side to accelerate the rise of the room temperature, and when the temperature of the hot water in the cistern tank 3 becomes sufficiently high, the first passage By closing the water control valve 12 and opening the second water flow control valve 13 to circulate the hot water from the second hot water outlet 5, the hot water having a stable temperature can be supplied to the radiator 7.

[0007]

As described above, in the present invention, a partition in the shape of a partition is provided inside the cistern tank so as to face the hot water inlet, and at the start of the operation, the second passage provided on the side opposite the hot water inlet is provided. The water control valve is closed, the inflowing hot water is retained at the hot water inlet side of the cistern tank, and is supplied to the radiator from the first hot water outlet through the first water passage control valve, thereby speeding the rise of the emission temperature of the radiator. When the predetermined discharge temperature is reached, the first water flow control valve is closed, the second water flow control valve is opened, and the heat is supplied to the radiator to make the hot water temperature in the cistern tank uniform. The stable operation of the hot water heater can be performed.
