れる。 When water is supplied from the water supply port 5 and a switch (not shown) for the burner 7 is turned on while the heat exchanger 8 is full of water, the hot water temperature detector 6 detects the temperature, and the burner 7 starts operating. After that, when the water near the hot water temperature sensor 6 is heated and reaches the set temperature of the hot water temperature sensor 6,
Stop the operation of burner 7. When you open the hot water faucet (not shown) in this state, the water supply pressure will cause the water supply port 5 to open.
Water supplied from the second header 2 and guided into the second header 2 passes through a plurality of water pipes 3 while being pushed up from the second header 2, and is led into the first header 1. When the water near the hot water temperature detector 6 falls below the set temperature of the hot water temperature detector 6, the burner 7 starts operating and is heated while passing through the plurality of water pipes 3,
Hot water is discharged from the hot water supply port 4 via the first header 1.

ばならないという問題をも有していた。 In this configuration, it is necessary to weld the first header 1 and the plurality of water pipes 3 and the second header 2 and the plurality of water pipes 3, and the number of welding points is extremely large, which increases the number of welding man-hours. In addition, the combustion gas 9 generated from the burner 7
In order to prevent leakage to the outside of the heat exchanger 8 through the water pipes 3, a heat insulating material 10 and an outer cylinder 11 must be provided outside the heat exchanger 8 to provide sufficient heat insulation and securely seal. I had a problem.
Also, in this configuration, the mixing tank 12 is essential. In other words, water heaters equipped with this type of multi-tube once-through heat exchanger aim to be more compact in terms of installation space and to save resources, as well as being more efficient in use.
Since we want hot water immediately when we open the hot water faucet, we have reduced the amount of canned water in the multi-tube once-through heat exchanger. However, when the amount of water in the can is reduced, the temperature rise rate of the water in the heat exchanger becomes faster, and the overshoot after being detected by the hot water temperature detector 6 becomes larger.As a result, without the mixing tank 12, the range of fluctuation in the outlet temperature becomes The mixing tank 12 is indispensable for the purpose of preventing such problems, such as discomfort and burns during use. However, since the conventional mixing tank 12 is installed outside the heat exchanger, when there is a risk of freezing in the severe cold, it is possible to prevent the inside of the heat exchanger from freezing by operating the burner 7, but the freezing inside the mixing tank 12 Therefore, it is necessary to attach an electric heater 14 or the like to the mixing tank 12 and keep it warm with a heat insulating material 15.

ことはなくなる効果がある。 In the above configuration, the multi-tubular once-through heat exchanger 1 is formed by welding only the longitudinal joints, so that the number of welding steps is reduced and the reliability of the welded portion is improved. Next, the operation will be explained. The burner 1 is supplied with water from the water supply port 10 and the multi-tubular once-through heat exchanger 1 is filled with water.
When switch 2 (not shown) is turned on, the hot water temperature detector 11 detects the temperature, and the burner 12 starts operating. Thereafter, when the water near the hot water temperature detector 11 is heated and reaches the set temperature of the hot water temperature detector 11, the operation of the burner 12 is stopped. When you open the hot water faucet (not shown) in this state, the water supply pressure will cause water inlet 1 to open.
Water is supplied from the second header 7 and passed through a plurality of water pipes 8 while being pushed up from the second header 7, and is led into the lower part 4 of the first header. When the water near the hot water temperature sensor 11 falls below the set temperature of the hot water temperature sensor 11, the burner 12
The combustion gas 14 is disturbed by the baffle body 13 while passing through the plurality of water pipes 8, promotes heat exchange, and is heated. Hot water is discharged from the hot water supply port 9 via the top 5. If the amount of hot water is low, burner 1
2, and when it reaches the set temperature of the hot water temperature detector 11, the operation of the burner 12 is stopped. However, since the amount of water in the can is small, the hot water temperature in the lower part of the first header 4 does not match the set temperature of the hot water temperature detector 11. The water temperature in the lower part of the first header 4 decreases due to water supply, and the hot water temperature detector 11 detects this and starts operating the burner 12, but the temperature in the lower part of the first header 4 decreases. The hot water temperature becomes lower than the set temperature of the hot water temperature detector 11 due to the detection delay of the hot water temperature detector, and as a result, the hot water temperature in the first header lower 4 fluctuates more than the set temperature range of the hot water temperature detector. It turns out. Although the range of hot water temperature fluctuation inside the first header is large,
While the hot water passes through the hot water supply port 9 and is discharged from the hot water supply port 9, the fluctuation range of the temperature of hot water discharged from the hot water supply port 9 can be reduced due to the mixing effect, and a comfortable and stable hot water temperature can be obtained when hot water is used. In addition, by operating burner 12 even when there is a risk of freezing during the severe cold season, the first
Since the header top 5 is also heated by natural convection through the connecting pipe 6, it will not freeze.
The high-temperature combustion gas 14 generated from the burner 12 is disturbed by the baffle body 13 to promote heat exchange in the plurality of water pipes 8, and after the heat exchange is completed, the combustion exhaust gas is passed around the entire circumference between the plurality of water pipes 8 and the metal plate 15. Since the metal plate 15 between the water pipes 8 and the water pipes 8 does not leak outside the heat exchanger 1 other than the exhaust port 16,
Even if it comes into contact with combustion exhaust gas, it becomes high temperature due to heat conduction to the water pipe 8, and there is no problem with heat resistance.

なる。Effects of the Invention According to the present invention, compared to the conventional configuration consisting of first and second headers and a plurality of water pipes, the number of welding steps can be greatly reduced, and the reliability of the welded part can be improved.
Furthermore, since the water pipes are connected by metal plates, combustion gas does not leak to the outside, and the temperature of the metal plates is reduced by heat conduction to the water pipes, improving the heat resistance of the metal plates. In addition, the water supplied from the water outlet is pushed up from the second header, heated while passing through multiple water pipes, collected under the first header, and mixed on the first header via the connecting pipe. Since the hot water is discharged from the hot water supply opening, the range of fluctuation in the temperature of the hot water discharged is reduced, and a stable and comfortable hot water temperature can be obtained during use.In addition, by operating the burner even when there is a risk of freezing in the coldest season, the first header The top is also heated, eliminating the problem of freezing.
