Problems solved by technology

Due to the influence of the heating surface, the heat loss is serious and the gas utilization rate is not high
At the same time, it is easy to cause the water temperature to be unstable, and it is also easy to burn out the water heater.
[0004] Forced discharge gas water heaters all need power supply, or external power supply, or battery installation, once the power is cut off or the battery is exhausted, the water heater cannot be used normally, affecting people's lives
[0005] The transmission gas water heater adopts the self-flowing fire exhaust combustion method, the heating temperature is about 1050 ℃, and the heat loss is large, and the gas utilization rate is low
[0006] Traditional water heaters cannot be turned on and heated immediately. When using them, the water heater and the cold water in the water pipe between the water heater and the faucet must first be released before normal use. First, it is very inconvenient to use, and second, water resources are seriously wasted

Embodiment 1

[0065] see figure 1 and figure 2 . The heat exchange fins 10 described in this embodiment schematically present six heat exchange tubes 11 parallel to each other and equal in length, and the distance between two adjacent heat exchange tubes 11 is equal. Two adjacent heat exchange tubes 11 are fixedly connected by six connecting plates 12 arranged at equidistant intervals, and there is a through hole 13 between adjacent two connecting plates, which is an important part of the flue in use. During installation, the heat exchange fins 10 are placed horizontally.

[0066] Arranging fins 14 on the exchange tube 11 can increase the heat-reducing area of ​​the heat exchange fins, and arranging fins under the heat exchange tubes can also prolong the time that the hot gas stays below the heat exchange fins 10. According to design requirements, the fins 14 It is arranged on one side or both sides of the heat exchange sheet 10. figure 2 It shows the situation that fins 14 are provid...

Embodiment 2

[0069] see figure 2 and Figure 8 . The heat exchanger described in this embodiment includes the heat exchange fins 10 described in Embodiment 1. The shape and structure of the heat exchange fins 10 have been clearly described in Embodiment 1, and will not be repeated in this embodiment. This embodiment schematically presents nine heat exchange fins 10 . Each heat exchange fin 10 is arranged horizontally, the heat exchange fins 10 are stacked and staggered, and the heat exchange fins are arranged equidistantly in the vertical direction. The heat exchange tubes 11 are all connected in series with end caps at both ends of the heat exchange fins 10, of course, part of them can also be connected in series.

[0070] The end cover is divided into two parts, namely an outer end cover 21 and an inner end cover 24. A plurality of connecting water tanks 23 are horizontally arranged on the outer end cover 21, and a cold water inlet is arranged on one of the two outer end covers. 26...

Embodiment 3

[0073] see Figure 4 to Figure 18 . The gas water heater 100 described in this embodiment includes a water heater casing, a fire pan, an igniter 102, a cold water pipe and a hot water pipe 106. The cold water enters through the cold water pipe and flows out from the hot water pipe after being heated. An air intake pipe is installed at the lower end of the fire pan. 44. It also includes a condensation jacket 30, a combustion chamber lower cover 46, a blower fan 101, a lifting mechanism, self-generating equipment and a zero cold water emptying mechanism. These devices can be selectively installed according to their respective functions. Correspondingly, if a certain function is not selected, the existing technology will be used to replace it if necessary. For example, when self-generating equipment is not used, the external 220V voltage power supply technology of the prior art is used. This embodiment provides that all functions are concentrated into the same gas water heater...

Abstract

The invention discloses a fuel gas water heater. The fuel gas water heater comprises a heat exchanger. The heat exchanger is formed by a plurality of heat exchange sheets arranged in parallel and an end cover. The water heater comprises a water heater casing, a heat exchange body, a fire disc, an ignitor, a cold water pipe and a hot water pipe, wherein the heat exchanger is mounted in a condenser jacket. Compared with the prior art, the fuel gas water heater is higher in heat exchange efficiency, the energy utilization rate of the water heater is high, and the heat loss is less.

Description

technical field [0001] The invention belongs to the field of household appliances, and relates to a gas water heater and parts thereof, in particular to a heat exchanger and a multifunctional energy-saving gas water heater. Background technique [0002] A water heater is a device that raises the temperature of cold water into hot water within a certain period of time, including electric water heaters, gas water heaters, solar water heaters, and air energy water heaters. [0003] Existing gas water heater is to adopt single pipe heat exchanger. Due to the influence of the heating surface, the loss of heat energy is serious, and the utilization rate of gas is not high. At the same time, it is easy to cause unstable water temperature, and it is also easy to burn out the water heater. [0004] Forced exhaust type gas water heaters all need power supply, or external power supply, or install battery, once power failure or battery run out, water heater just can't normally use, af...
