[0002] A gas water heater, also known as a gas water boiler, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] A gas water heater includes a pipeline system formed by connecting several pipelines for water supply to circulate, enabling water to flow according to the required path. In some existing gas water heater pipeline systems, a sterilization lamp (such as an ultraviolet lamp) is provided; by irradiating the water in the pipeline system with the sterilization lamp, the water in the pipeline system is sterilized to optimize the water quality so as to output higher-quality hot water.

[0004] It should be noted that during assembly or transportation, the pipeline system is often easily impacted or struck, resulting in the sterilization lamp in it being easily damaged by the impact and broken. Once the sterilization lamp is broken, its fragments will flow with the water in the pipeline system, which not only easily damages the pipeline system, but also the fragments are likely to flow out with the water, causing safety accidents, which is very dangerous.

Specific embodiments

[0036] The following is a specific example description of the present utility model in combination with embodiments:

[0037] Embodiment 1:

[0038] A pipeline system for supplying water and flowing in a gas water heater.

[0039] Specifically, as shown in Attachment Figure 1 to Attachment Figure 4 The pipeline system in this embodiment includes a water supply pipeline 1. The water supply pipeline 1 is a long pipeline formed by connecting several pipes and joints, and has a conveying flow channel 1.1 for water supply to flow through. The water supply pipeline 1 is extended according to the path where the water needs to flow, so that the water can flow in the conveying flow channel 1.1 according to the required path.

[0040] In order to sterilize the water flowing in the water supply pipeline 1 to optimize the water quality. In this embodiment, a sterilization lamp 3 is provided. The sterilization lamp 3 is a lamp assembly having, for example, an ultraviolet lamp, which can emit ultraviolet rays with a wavelength of 265 - 580 mn, irradiate the water flowing in the water supply pipeline 1, and sterilize to purify the water quality.

[0041] Specifically, as shown in Attachment Figure 2 to Attachment Figure 3As shown in the figure, in this embodiment, a side pipe 2 is provided on one side of the water supply pipe 1. The side pipe 2 is welded to one side wall of the water supply pipe 1; or the side pipe 2 is a part of the joint that constitutes the water supply pipe 1. At the same time, a storage cavity 2.1 is formed inside the side pipe 2 in a cavity shape, as shown in the appendix Figure 2 As shown in the figure, the lower end opening of the storage cavity 2.1 is communicated with the conveying channel 1.1.

[0042] In this embodiment, the germicidal lamp 3 is arranged in the storage cavity 2.1 to avoid the influence of the germicidal lamp 3 on the flow of water in the conveying channel 1.1.

[0043] In actual production, it is found that when the pipeline system is assembled into the gas water heater as a whole, or when the pipeline system is transported and moved in the gas water heater, it is very easy to receive impacts or shocks, resulting in the breakage of the germicidal lamp 3. After the germicidal lamp 3 is damaged, the generated fragments are likely to fall from the storage cavity 2.1 into the conveying channel 1.1 and flow with the water in the conveying channel 1.1. This not only easily damages the water supply pipe 1, but also easily causes safety accidents when flowing out with the water, which is very dangerous.

[0044] Based on this, as shown in the appendix Figure 2 to appendix Figure 4 As shown in the figure, in this embodiment, a protective cover 4 is provided in the channel formed by the connection of the storage cavity 2.1 and the conveying channel 1.1, which is located on the side of the germicidal lamp 3 facing the conveying channel 1.1; and a plurality of light-passing holes 4.1 are provided on the protective cover 4. The light-passing holes 4.1 are holes provided on the protective cover 4 for communicating the storage cavity 2.1 and the conveying channel 1.1. The mesh number of the light-passing holes 4.1 provided on the protective cover 4 is generally preferably 30 to 60 meshes.

[0045] At this time, the protective cover 4 with the light-passing holes 4.1 forms a mesh cover that prevents the germicidal lamp 3 from falling into the conveying channel 1.1. When the germicidal lamp 3 (as described above, the germicidal lamp 3 is a lamp assembly with an ultraviolet lamp, such as a UV lamp) is broken as described above, the fragments will be blocked in the storage cavity 2.1 by the protective cover 4 to avoid falling into the conveying channel 1.1. Moreover, when the germicidal lamp 3 emits ultraviolet rays as described above, the ultraviolet rays can irradiate from the storage cavity 2.1 to the conveying channel 1.1 through the light-passing holes 4.1 to sterilize the water flow in the conveying channel 1.1.

[0046] In order for the sterilizing lamp 3 to better sterilize the water flow in the conveying channel 1.1, the protective cover 4 has a transparent light-transmitting portion through which the light emitted by the sterilizing lamp 3 can pass and irradiate into the conveying channel 1.1. For example, part or all of the protective cover 4 is made of transparent acrylic board to form a light-transmitting portion, so that when the sterilizing lamp 3 emits ultraviolet rays as described above, the ultraviolet rays can directly pass through the light-transmitting portion to irradiate into the conveying channel 1.1 to sterilize the water flow in the conveying channel 1.1. Alternatively, the main body of the protective cover 4 is made of stainless steel, and a part is made of transparent acrylic board, and the transparent part forms a light-transmitting portion.

[0047] In order to better accommodate the fragments when the sterilizing lamp 3 is broken; as shown in the appendix Figure 3 As shown, the protective cover 4 can also be provided with an object-catching groove 4.2, and the notch of the object-catching groove 4.2 is arranged facing the sterilizing lamp 3. After the sterilizing lamp 3 is broken, more of its fragments can be placed in the object-catching groove 4.2 instead of flowing around; it is convenient to process the fragments later.

[0048] For the protective cover 4, it can be arranged in the conveying channel 1.1 and cover the lower end opening of the storage cavity 2.1 in the direction from the conveying channel 1.1 to the storage cavity 2.1. However, in this way, the protective cover 4 is likely to obstruct the water flow in the conveying channel 1.1.

[0049] Therefore, in this embodiment, the protective cover 4 is preferably installed in the storage cavity 2.1. Moreover, the outer contour size of the protective cover 4 is preferably adapted to the inner wall contour of the storage cavity 2.1, so that the protective cover 4 can be adaptively fitted into the storage cavity 2.1 as shown in the appendix Figure 4 to better prevent the sterilizing lamp 3 from falling into the conveying channel 1.1.

[0050] Furthermore, in order to make the protective cover 4 more stably placed in the storage cavity 2.1, as shown in the appendix Figure 2 to the appendix Figure 4 As shown, a limiting portion 2.2 is convexly arranged on the side wall of the storage cavity 2.1; the protective cover 4 is provided with a lapping portion 4.3, and in the direction from the storage cavity 2.1 to the conveying channel 1.1, the lapping portion 4.3 abuts against the limiting portion 2.2 to prevent the protective cover 4 from shifting into the conveying channel 1.1.

[0051] To improve the limiting effect and the positioning stability of the protective cover 4, the limiting portion 2.2 is preferably an annular protrusion arranged around the inner wall of the storage cavity 2.1, and the lapping portion 4.3 is an annular flange structure arranged around the outer edge of the protective cover 4 and adapted to lap on the annular limiting portion 2.2.

[0052] On the above basis, in order to facilitate the installation of the protective cover 4.

[0053] As shown in the appendix Figure 2To the appendix Figure 4 As shown in the figure, at one end of the storage cavity 2.1 away from the conveying channel 1.1 (for example, the upper end of the storage cavity 2.1 shown in the appendix Figure 2 ), an installation opening 2.3 is provided. The diameter of the installation opening 2.3 is set according to the sizes of the germicidal lamp 3 and the protective cover 4 to form an opening for the germicidal lamp 3 and the protective cover 4 to enter and exit the storage cavity 2.1.

[0054] Meanwhile, a cover plate 5 for covering the installation opening 2.3 is provided at the installation opening 2.3, and the cover plate 5 is detachably fixed to the side pipe 2.

[0055] Specifically, as shown in the appendix Figure 1 , a support portion 2.4 is convexly provided on the outer edge of the installation opening 2.3. The cover plate 5 is fixed on the support portion 2.4 through a fastener 6 (such as a screw) and covers and seals the installation opening 2.3.

[0056] During assembly, by removing the cover plate 5, the protective cover 4 can be placed into the storage cavity 2.1 from the installation opening 2.3. By overlapping the overlapping portion 4.3 of the protective cover 4 on the limiting portion 2.2, the protective cover 4 can be installed in place. Subsequently, the germicidal lamp 3 is placed into the storage cavity 2.1 from the installation opening 2.3, and then the cover plate 5 is covered on the installation opening 2.3, and the installation is completed.

[0057] In this embodiment, the cover plate 5 is detachably fixed to the side pipe 2 through at least two fasteners 6 (such as screws), and the two fasteners 6 are respectively placed on both sides of the installation opening 2.3 to more firmly fix the cover plate 5.

[0058] Furthermore, in the above solution, the germicidal lamp 3 can be fixed in the storage cavity 2.1 through structures such as buckles or screws.

[0059] In this embodiment, the germicidal lamp 3 is preferably fixed to the side of the cover plate 5 facing the storage cavity 2.1. On the one hand, this enables the germicidal lamp 3 to be disassembled and assembled synchronously with the cover plate 5, improving the convenience of subsequent maintenance; on the other hand, it avoids additionally setting a positioning structure in the narrow space of the storage cavity 2.1.

[0060] Specifically, in this embodiment, the germicidal lamp 3 includes: a mounting post 3.1, a lamp shade 3.2, a lamp tube 3.4, and a power supply structure for supplying power to the lamp tube 3.4.

[0061] Among them, the mounting post 3.1 is fixed to the side of the cover plate 5 facing the storage cavity 2.1 through, for example, a screw structure, or the mounting post 3.1 is configured to be integrally formed with the cover plate 5 to fix the germicidal lamp 3 to the cover plate 5. A lamp shade 3.2 made of a transparent material such as an acrylic plate is sleeved on the outer periphery of the mounting post 3.1; and, as shown in the appendix Figure 3As shown in the figure, an installation cavity 3.3 that is not connected to the external space is formed at an interval between the end of the lamp cover 3.2 and the installation post 3.1.

[0062] The lamp tube 3.4 is, for example, an ultraviolet lamp tube that can emit ultraviolet rays, and it is adaptively installed in the installation cavity 3.3. For example, an installation groove can be provided on the installation post 3.1, and the lamp tube 3.4 can be positioned and embedded in this installation groove. At this time, the power supply structure can be: a battery provided in the installation post 3.1 and electrically connected to the lamp tube 3.4 to supply power to the lamp tube 3.4; or, a power cord provided in the installation post 3.1, with one end electrically connected to the lamp tube 3.4 and the other end passing through the cover plate 5 and exposed. By connecting the exposed end of the power cord to an external power supply, power supply to the lamp tube 3.4 can be achieved.

[0063] The lamp cover 3.2 is preferably detachably sleeved on the installation post 3.1 through, for example, a threaded structure to facilitate the maintenance of the lamp tube 3.4.

[0064] On the above basis, as shown in the attached Figure 1 to the attached Figure 4 As shown in the figure, an elastic gasket 7 can also be additionally provided, which is preferably made of elastic materials such as rubber or silica gel.

[0065] The gasket 7 is compressively filled between the sterilization lamp 3 and the side wall of the storage cavity 2.1. On the one hand, it can support the sterilization lamp 3 and improve the installation stability of the sterilization lamp 3 so that it can perform irradiation sterilization more stably; on the other hand, it can form an elastic buffer structure between the sterilization lamp 3 and the inner wall of the storage cavity 2.1, reducing the possibility of the sterilization lamp 3 being damaged after being impacted. Moreover, when the installation opening 2.3 is formed as described above, the gasket 7 can also form an elastic seal between the sterilization lamp 3 and the inner wall of the storage cavity 2.1 to prevent the water flow in the storage cavity 2.1 from flowing out through the installation opening 2.3.

[0066] The gasket 7 is preferably provided to fit the outer contour of the sterilization lamp 3, and is an annular member that is adapted to be sleeved on the outer periphery of the sterilization lamp 3, so as to better position and protect the sterilization lamp 3.

[0067] In this embodiment, as shown in the attached Figure 3 As shown in the figure, in order for the gasket 7 to be more easily inserted between the sterilization lamp 3 and the inner wall of the storage cavity 2.1, in the direction from the sterilization lamp 3 to the side wall of the storage cavity 2.1, the gasket 7 successively includes: a gasket body 7a, and a sealing rib 7b protruding from the gasket body 7a.

[0068] When the gasket 7 is an annular member, the gasket body 7a is an annular member adapted to be sleeved on the outer periphery of the sterilization lamp 3, and the sealing rib 7b is an annular protrusion surrounding the gasket body 7a.

[0069] Further, when the installation opening 2.3 is formed as described above and the cover plate 5 is mounted on the installation opening 2.3, in order to better improve the sealing effect. As shown in the attached Figure 3 and the attached Figure 4 As shown in the figure, the sealing gasket 7, specifically the outer periphery of one end of the sealing gasket body 7a close to the cover plate 5 is provided with a protruding flange portion 7.1; the flange portion 7.1 is also made of elastic materials such as rubber or silica gel, and is filled in a compressed manner between the cover plate 5 and the side pipe 2.

[0070] Furthermore, the side wall of the installation opening 2.3 is provided with a clamping groove 2.31 that opens towards the cover plate 5; the flange portion 7.1 is fitted and filled in the clamping groove 2.31 to improve the installation stability of the flange portion 7.1, so as to form a seal more stably between the cover plate 5 and the side pipe 2.

[0073] The heat exchanger housing 8 has a flue gas flow path for the high-temperature flue gas generated by the combustion of the burner to flow. A part of the water supply pipeline 1 in the pipeline system is coiled outside the heat exchanger housing 8, or has a part inserted into the heat exchanger housing 8 and placed in the flue gas flow path. When high-temperature flue gas flows through the flue gas flow path, the water in the water supply pipeline 1 can exchange heat with the high-temperature flue gas to increase the temperature.
