Problems solved by technology
[0007] Existing water heaters have their disadvantages. The top of the combustion chamber is directly connected to the exhaust duct. In the heat exchange area, there is a large continuous air mass space for high-temperature pyrotechnics. The temperature of the flue gas in the duct is high, resulting in energy loss; there are also some water heaters with open combustion chambers, which radiate a certain amount of heat from the combustion chamber to the outside during operation, and a small part of the high-temperature pyrotechnics generated by combustion will rise along the inner side of the water heater shell to Exhaust flue, forming energy loss

Embodiment Construction
[0021] The water heater shown in Fig. 1 is made up of combustion chamber 1, heat exchanger 4, flue exhaust duct 7 and thermal insulation layer 6, and heat exchanger 4 completely separates combustion chamber 1 from flue exhaust duct 7. The top of the combustion chamber communicates with the bottom of the heat exchanger, and the top of the heat exchanger communicates with the exhaust duct; the side surfaces of the heat exchanger and the combustion chamber are tightly packed and filled with a thermal insulation layer impermeable to smoke, and the bottom of the combustion chamber is insulated Heat layer wrap. It can be seen from the schematic diagram that the combustion zone and the heat exchange zone of the water heater are independent, with clear boundaries, and the two zones do not overlap or include each other.
[0022] The heat exchanger is a metal water-holding box surrounded by its lower surface 2, upper surface 5 and side surfaces. The heat exchanger has a water outlet 8 a...

The invention discloses a heat exchange method and the water heater of the combustion water heater which is made up of the burning room, the heat exchanger, the smoke discharging channel, the temperature insulating layer and burning control system. The burning room is not connected with the smoke discharging channel which is divided by the heat exchanger. The top of the burning room is connected with the heat exchanger bottom and the top is connected with the smoke discharging channel. The side surface of the heat exchanger and the burning room are filled with the airtight temperature insulating layer which covers the burning room bottom. The burning region is separated from the heat exchanging region. The level projection of the heat exchanger and the burning room has their own order which has no overlapping region. The heat exchanger is the tank which can stores the water and has the metal heat exchanging cavity in upper and lower surface. The metal heat exchanging cavity has at least one. When the heater works the smoke fire pass the water through the cavity hole.
Description
technical field [0001] The invention relates to a heat exchange method and a water heater device of a combustion water heater, in particular to a combustion water heater comprising a heat exchanger, a combustion chamber, a flue exhaust duct and a thermal insulation layer. Background technique [0002] A water heater is a device that produces hot water. Currently commercially available combustion water heaters and wall-hung boilers producing hot water all include heat exchangers, combustion chambers and flue exhaust ducts. [0003] A heat exchanger is a device for exchanging energy between a high-temperature medium and a low-temperature medium. [0004] The combustion chamber is a device that burns fuel to convert material energy into heat energy. [0005] In existing water heaters and wall-hung boilers, the top of the combustion chamber is directly connected to the flue; The metal water pipe placed in high-temperature pyrotechnics, when working, water passes through the p...
