[0020] To make the objectives, technical solutions, and advantages of this utility model clearer and more explicit, the content of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely for explaining this utility model and not for limiting it. Furthermore, it should be noted that, for ease of description, only the parts related to this utility model are shown in the accompanying drawings, not all of them.

[0021] like Figure 1 and 2 As shown, this embodiment proposes a quick connection structure for water heater pipes, including:

[0022] The casing 1 includes at least a heat exchanger unit 2 and a burner unit 3 inside;

[0023] The L-shaped quick-connect gas connector 4 is installed at the bottom of the housing 1, and its output end is connected to the gas inlet end of the burner unit 3.

[0024] The L-shaped quick-connect water inlet connector 5 is installed at the bottom of the housing 1, and its output end is connected to the water inlet end of the heat exchanger unit 2.

[0025] The L-shaped quick-connect water outlet connector 6 is installed at the bottom of the housing 1, and its input end is connected to the water outlet end of the heat exchanger unit 2.

[0026] Among them, the input end of the L-type quick-connect gas connector 4, the input end of the L-type quick-connect water inlet connector 5, and the output end of the L-type quick-connect water outlet connector 6 all face the front of the housing 1. The "front" mentioned here refers to the front of the panel of the housing 1.

[0027] In this embodiment, by providing L-shaped quick-connect gas connector 4, L-shaped quick-connect water inlet connector 5, and L-shaped quick-connect water outlet connector 6 facing forward at the bottom of the housing 1, the user can quickly connect the matching quick-connect interfaces at the ends of the water pipe and gas pipe to the L-shaped quick-connect gas connector 4, L-shaped quick-connect water inlet connector 5, and L-shaped quick-connect water outlet connector 6 respectively, provided that the connector ports are visible. The installation process is simple.

[0028] In one example, the bottom of the aforementioned housing 1 is a detachable base plate 101. The inlet end of the burner unit 3, the water inlet end of the heat exchanger unit 2, and the water outlet end are all provided with non-detachable first connectors 7, which are detachably mounted on the upper surface of the base plate 101 via the first connectors 7. The input end of the L-shaped quick-connect gas connector 4, the input end of the L-shaped quick-connect water inlet connector 5, and the output end of the L-shaped quick-connect water outlet connector 6 are all provided with non-detachable second connectors 8, which are respectively mounted on the lower surface of the base plate 101 via the second connectors 8 and then fixed to the corresponding first connectors 7. Through the fixing relationship between the first connectors 7 and the second connectors 8, the L-shaped quick-connect gas connector 4, the L-shaped quick-connect water inlet connector 5, and the L-shaped quick-connect water outlet connector 6 are fixed to the lower end of the base plate 101, with provisions for future replacement.

[0029] Optionally, the first connector 7 is a butterfly-shaped gasket welded to the ends of the air inlet of the burner unit 3, the water inlet of the heat exchanger unit 2, and the water outlet. The butterfly gasket has first mounting holes on both sides. The second connector 8 is a butterfly-shaped gasket welded to the middle of the outer wall of the L-shaped quick-connect gas connector 4, the L-shaped quick-connect water inlet connector 5, and the L-shaped quick-connect water outlet connector 6. The butterfly gasket has second mounting holes on both sides that match the first mounting holes. When the user needs to replace any connector, the fastener can be removed from between the first connector 7 and the second connector 8, the new connector can be reinstalled in the corresponding position, and the fastener can be installed.

[0030] To further improve the accuracy of user installation, another optional solution is to use the L-shaped quick-connect gas connector 4, L-shaped quick-connect water inlet connector 5, and L-shaped quick-connect water outlet connector 6 as interfaces of different diameters. By setting the interfaces to different diameters, it is convenient for users to observe, and only water pipe and gas pipe interfaces of the corresponding size can be successfully installed. This is a foolproof design to prevent users from mixing up water pipe and gas pipe interfaces.

[0031] The above embodiments are merely illustrative of the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model.
