Description

DETAILED DESCRIPTION OF THE INVENTION This invention is an improved water heater.The purpose of this invention is to use a partition plate to open the water canister of the water heater, that is, approximately the middle of the boiler, vertically in a circular manner so that the upper part can be used for both water supply and hot water supply. In addition to forming a heating chamber in which a small amount of water can be rapidly heated in the lower part of the chamber, a hot water supply pipe using a pressurized pump is installed to function as an instantaneous water heater along with ignition, and a riser pipe is also installed. The lower end of the riser pipe is opened into the partition plate, and the upper end passes through the hot water chamber and opens into the extension cylinder.When the hot water is not in use or is not used, the hot water in the heating chamber is guided to the boiling water chamber through the riser pipe for convection. To provide a hot water supply device which is capable of using a large amount of hot water by heating water in a hot water chamber through circulation through a chimney, heating through a chimney, and further using a pressure pump in combination.

Hereinafter, referring to the attached drawings, A is a boiler, and a partition plate 2 is installed approximately in the middle of the main body 1.
The upper part is divided into a hot water chamber 1a, and the lower part is divided into two upper and lower chambers: a combustion chamber (heat exchange chamber) 1b.The lower combustion chamber 1b has a large-diameter combustion tube 4 formed in the center to form the main body. 1 and the back surface of the partition plate 2 to form a narrow water passage, and a large number of water pipes 3 are installed inside the combustion tube 4 at the lower end of the combustion tube 4. Further, the upper end is mounted so as to face the upper surface, that is, the back surface of the partition plate 2, and the communication pipe 8 is mounted on one side of the outer periphery of the combustion chamber 1b. The hot water chamber 1 is fixed close to the upper surface, and the lower end is fixed close to the bottom of the combustion chamber 1b.
The hot water in chamber a is naturally lowered and supplied into the combustion chamber 1b, and the lower end of the riser pipe 12 is attached to the partition plate 2, and the upper end is provided in an extension tube 13 above the hot water chamber 1a, which will be described later.
The chimney 17 of the combustion tube 4 passes through the center of the hot water chamber 1a with the opening protruding outward, and the connecting pipe 9 is connected to the other side so that the upper end thereof is connected to the combustion chamber 1b.
The upper and lower ends are fixed close to the bottom of the combustion chamber 1b, respectively, and a pressurizing pump P and a hot water supply pipe 10 are attached to this connecting pipe 9, and the hot water supply pipe 10 is connected to a pipe 11 piped to a hot water supply point. do. By the way, burner C
When the water in the combustion chamber 1b is heated up, the water in the combustion chamber 1b is instantaneously heated and can be used as an instantaneous water heater to supply hot water.
The water in a is also heated and becomes hot water, and this hot water is supplied from the communication pipe 8 as it is used, so that hot water at a predetermined temperature can be constantly supplied.

Next, a water storage tank B is separately formed and attached to one of the outer end surfaces of the water supply and hot water chamber 1a, and a circular distributed water supply pipe is installed along the inner circumferential surface of the upper part of the inside of the hot water chamber 1a with a water supply pipe 6. 7 to supply water in a distributed manner from above inside the water supply and hot water room 1a. Also water tank B
A hole tap 5 is attached inside the container so that a predetermined amount of water can be stored at all times. Further, on the other side of the upper end surface of the water supply and hot water chamber 1a, an extension tube 13 is provided separately or in the same body so as to communicate with the inside of the water storage and hot water chamber 1a, and the lower end is attached to the partition plate 2, and the combustion chamber 1
Upper end opening 12a of the rising pipe 12 communicating with b
is opened at the upper surface of the hot water storage surface 14 of the extension tube 13, and the hot water storage surface 14 is designed and formed in advance so that it is flush with the water surface in the water storage tank B. The water is heated by the partition plate 2, riser pipe 12, and chimney 17 to become hot water.

Next, to explain the function of the riser pipe 12, as mentioned above, when hot water is being used, the opening 12a of the riser pipe 12 protrudes from the water surface 14 of the extension tube 13 and heats the water in the hot water chamber 1a. However, combustion chamber 1b
When the use of hot water in the combustion chamber 1b is extremely low or the use is stopped, the hot water in the combustion chamber 1b will not extinguish the ignition of the burner C, and if it becomes a small flame, it will expand and cause the riser pipe 1 to ignite.
The water level in the extension cylinder 13 rises, and the opening 12a is submerged and the hot water in the water supply and hot water chamber 1a is further heated by natural convection, thereby causing the water in the combustion chamber 1b to rise. Warmed hot water is supplied through a communication pipe 8, allowing a large amount of hot water to be used. In addition, if a large amount of hot water is required to be used, if the burner C is not set to a small flame and continues to burn, the temperature of the water will reach around 75°C and expand, overflowing from the opening 12a of the riser pipe 12. This further heats the water in the water supply and hot water chamber 1a described above, and in combination with the fact that water is supplied in a dispersed state through the sprinkler pipe 7 into the hot water chamber 1a, the temperature of the hot water suddenly increases. There is no drop in water, and a large amount of hot water can be used continuously. C in the drawing is a burner, B
1 is a pump, 15 is a lid, and 16 is a drain pipe of the extension tube 13.

Since the present invention is constructed as described above, the lower combustion chamber 1b has a large-diameter combustion tube 4 with a narrow distance from the inner circumferential surface of the main body 1, so that water can pass through a narrow passage, and there are many passages. Since the water pipe 3 and the partition plate 2 are used as the ceiling plate of the combustion chamber 1b, the water in the combustion chamber 1b is instantaneously heated and functions as an instantaneous water heater. The upper water supply chamber becomes the hot water chamber 1a through the pipe 12, etc., and this hot water can be supplied to the combustion chamber 1b through the connecting pipe 8, so that it functions even more as an instantaneous water heater. A water storage tank B and an extension tube 13 are installed together to keep the water level 14 of both the same and the upper end opening 1 of the riser pipe 12 is installed.
2a protrudes above the water surface 14, and continues to heat the water in this state while hot water is being supplied, that is, while hot water is being used.When the hot water usage decreases and the use is further stopped, the combustion chamber 1b is opened from the riser pipe 12. Due to continued heating inside, hot water overflows from the opening 12a and enters the water supply and hot water chamber 1a.
By mixing with the water in the hot water chamber 1a, the water in the hot water chamber 1a can be further heated, making it possible to use a large amount of hot water. Moreover, due to the action of the riser pipe 12, there is no need to use valves or other machines or instruments, and therefore, it is possible to provide a device that is inexpensive, trouble-free, and trouble-free, and has many advantages. .
