In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present.

In an embodiment, please refer to fig. 1 and 2, a gas water heater 1 includes a combustion assembly and a heat exchange assembly, the combustion assembly includes a fan 31 and a burner 32, the burner 32 is horizontally arranged, the heat exchange assembly is horizontally arranged, and an air outlet direction of the fan 31 is horizontal, so as to drive smoke generated by the burner 31 to flow in a horizontal direction.

Gas heater, compare produced beneficial effect with the background art: arrange gas heater's combustor 32 and heat exchange assembly level to the air-out direction level that makes fan 31 can realize gas heater's flue gas horizontal flow, makes whole gas heater can realize transversely arranging, can be used to design more diversified product appearance, promotes user's aesthetic experience. Referring to fig. 1, compared with the prior art gas water heater with combustion heat exchange in the vertical direction, the appearance of the gas water heater can be greatly changed, so that the uniform product appearance is avoided, and the existing narrow product appearance design space is broken.

The burner 32 and the heat exchange assembly are horizontally arranged, and the air outlet direction of the fan 31 is horizontal, which means that the gas water heater mainly exchanges heat in the horizontal direction, and is different from the existing gas water heater in heat exchange in the vertical direction, but the air outlet directions of the burner 32, the heat exchange assembly and the fan 31 are not limited to be completely parallel to the horizontal line. While fig. 2 is only an embodiment, the specific form of the combustion assembly (including the fan 31 and the burner 32, etc.) and the heat exchange assembly (the heat exchange pipeline 21 and the heat exchange fins 22, etc.) should not be limited thereto, for example, the horizontally arranged burner 32 may be a cylindrical premix burner, a burner that sprays flame towards the horizontal direction, or a burner with other structure. The fan 31 may be an axial flow fan or a centrifugal fan.

Further, referring to fig. 2, the fan 31 is located at the air inlet end of the burner 32, and the air outlet direction of the fan 31 is parallel to the axis of the smoke exhaust pipe 123 in the gas water heater 1.

Therefore, the indoor installation space can be further greatly reduced, the appearance design of the indoor part can be more flexible, the through hole formed in the installed object is smaller, and the installation difficulty can be greatly reduced.

In addition, the diameter of the mounting section 111 may be set to not more than 200 mm. In a specific installation, the casing 10 can be installed on an outer wall, and the casing 10 has a function of discharging smoke outdoors, that is, directly discharging smoke outdoors through the smoke discharge pipe 123. In the prior art, when a gas water heater is installed, a smoke pipe needs to be additionally installed outside a machine, the gas water heater needs to discharge smoke outdoors through the smoke pipe which is separated from the gas water heater, and when the smoke pipe is additionally installed, a through hole needs to be formed in an outer wall generally. Because the tobacco pipe itself must be high temperature resistant material, it is worth very much, and ordinary gas heater is bulky, and the area that needs to occupy the installation wall body is also great, if the installation environment is unsatisfactory, probably need install longer tobacco pipe additional, not only influence the smoke evacuation effect, consume the resource, further destroyed the house ornamentation environment moreover. The diameter of the mounting section 111 is set to be not more than 200mm, the existing method for punching the smoke exhaust pipe of the range hood on the outer wall can be directly used, a common split smoke pipe is omitted, the smoke pipe is integrated on the shell 10, and the range hood is concise, attractive and practical.

Further, combustor and heat exchange assembly coaxial arrangement do benefit to the miniaturization that realizes the product, can be used to guarantee gas heater's heat transfer effect moreover.

As an embodiment of the coaxial arrangement of the burner and the heat exchange assembly, see fig. 2, the heat exchange assembly comprises a heat exchange pipe 21, the heat exchange pipe 21 is enclosed outside the burner 32, that is: arranging the burner 32 in the middle along the axis of the casing 10 and the heat exchange pipe 21 around the burner 32, the flue gas flows in the transverse direction, so that the heat exchange pipe 21 can effectively obtain the heat in the flue gas. Specifically, the heat exchange pipeline 21 is a coil pipe in a spiral direction; alternatively, the heat exchange pipeline 21 includes a vertical pipe parallel to the axial direction of the casing and an elbow joint for communicating with the vertical pipe. The combustor 32 may be configured as a premix combustor, such as a fully premixed combustor or a semi-premixed combustor. The combustor that will be located the middle part sets up to mixing formula combustor in advance, can realize the miniaturization of combustor on the one hand, is convenient for control tube-shape casing's diameter, and on the other hand carries out the full premix or half premix of gas and air at the inlet end, can avoid or reduce the demand of secondary air inlet, and then makes the inside more compact of product, further realizes the product miniaturization.

As another embodiment of the coaxial arrangement of the burner and the heat exchange assembly, the burner is enclosed outside the heat exchange assembly. The burner can be designed into a cylinder body with an annular cross section outline, the combustible gas is sprayed into a cavity between the inner wall and the outer wall of the cylinder body, the heat exchange assembly is enclosed in the cylinder body of the burner, and the flame generated by the burner faces the heat exchange assembly.
