Description

Technical Field

[0001] The utility model relates to the technical field of gas water heaters, and more specifically to a pipeline assembly and a gas water heater. Background Art

[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 assembly formed by connecting a plurality of pipelines for water supply to circulate, enabling water to flow along a required path. In some existing gas water heaters, a sterilization lamp (such as an ultraviolet lamp) is provided in the pipeline assembly; by irradiating the water in the pipeline assembly with the sterilization lamp, the water in the pipeline assembly is sterilized to optimize the water quality so as to output higher-quality hot water.

[0004] It should be noted that most of the existing sterilization lamps are directly placed in the water supply pipeline of the pipeline assembly, which not only hinders the water flow in the water supply pipeline, but also under the impact of the water flow, the sterilization lamp often cannot stably sterilize the water and is prone to failure. Summary of the Utility Model

[0005] One of the purposes of the present utility model is to provide, in view of the deficiencies of the existing technology, a pipeline assembly with a sterilization lamp that can more stably sterilize water.

[0006] Another purpose of the present utility model is to provide a gas water heater with the above pipeline assembly.

[0017] Further as a preferred solution, on the outer periphery near one end of the sealing gasket, there is provided: a protruding flange portion;

[0018] The flange portion has elasticity and is filled in a compressed state between the cover plate and the side pipe.

[0019] Further as a preferred solution, on the side wall of the installation opening, there is provided: a clamping groove opening towards the cover plate;

[0020] The flange portion is adaptively filled in the clamping groove.

[0021] Further as a preferred solution, in the channel formed by the connection of the storage cavity and the conveying flow channel, there is provided a protective cover, which is located on the side of the germicidal lamp facing the conveying flow channel and has a plurality of light passing holes to form: a mesh structure for preventing the germicidal lamp from falling into the conveying flow channel.

[0022] Further as a preferred solution, the protective cover is provided with an object clamping groove, and the notch of the object clamping groove is arranged towards the germicidal lamp.

Specific implementation mode

[0035] The following is a specific example description of the present utility model in combination with embodiments:

[0036] Embodiment 1:

[0037] The pipeline component is used for supplying water to flow in a gas water heater.

[0038] Specifically, as shown in Appendix Figure 1 to Appendix Figure 4 As shown, the pipeline component in this embodiment includes a water supply pipeline 1, which is a long pipeline formed by connecting several pipes and joints, and has a conveying flow channel 1.1 for water supply to flow. 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.

[0039] 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 component with an ultraviolet lamp, for example, which can emit ultraviolet rays with a wavelength of 265 - 580 mn to irradiate the water flowing in the water supply pipeline 1 for sterilization to purify the water quality. Specifically, as shown in Appendix Figure 2 to Appendix Figure 3 As shown, in this embodiment, a side pipe 2 is provided on one side of the water supply pipeline 1. The side pipe 2 is welded to one side wall of the water supply pipeline 1; or the side pipe 2 is a part of the joint constituting the water supply pipeline 1. At the same time, a storage cavity 2.1 is formed inside the side pipe 2 in a cavity shape, as shown in Appendix Figure 2As shown in the figure, the lower end opening of the storage cavity 2.1 is communicated with the conveying channel 1.1.

[0040] In this embodiment, the germicidal lamp 3 is arranged in the storage cavity 2.1. During operation, the ultraviolet rays emitted by the germicidal lamp 3 irradiate into the conveying channel 1.1 through the connection path between the storage cavity 2.1 and the conveying channel 1.1 to sterilize the water flow in the conveying channel 1.1. In this way, on the one hand, it can avoid the germicidal lamp 3 from hindering the flow of water in the conveying channel 1.1; on the other hand, the flowing water in the conveying channel 1.1 is not likely to impact the germicidal lamp 3, enabling the germicidal lamp 3 to sterilize the water more stably.

[0041] Further, as shown in the appended Figure 1 to the appended Figure 4 figure, a sealing gasket 7 can be additionally provided, which is filled between the germicidal lamp 3 and the side wall of the storage cavity 2.1 to fill the gap between the germicidal lamp 3 and the storage cavity 2.1 and support and position the germicidal lamp 3.

[0042] Furthermore, the sealing gasket 7 in this embodiment is preferably made of elastic materials such as rubber or silica gel and has elasticity. And the sealing gasket 7 is filled in a compressed state between the germicidal lamp 3 and the side wall of the storage cavity 2.1. In this way, on the one hand, it can support the germicidal lamp 3 and improve the installation stability of the germicidal lamp 3 so that it can irradiate and sterilize more stably; on the other hand, it can form an elastic buffer structure between the germicidal lamp 3 and the inner wall of the storage cavity 2.1, reducing the possibility of the germicidal lamp 3 being damaged after being impacted.

[0043] The sealing gasket 7 is preferably arranged to fit the outer contour of the germicidal lamp 3 and is an annular member that fits around the outer periphery of the germicidal lamp 3 to better position and protect the germicidal lamp 3.

[0044] On the above basis, to facilitate the installation of the germicidal lamp 3.

[0045] As shown in the appended Figure 2 to the appended Figure 4 figure, 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 appended Figure 2 figure) is provided with an installation opening 2.3, and the diameter of the installation opening 2.3 is set according to the size of the germicidal lamp 3 to form an opening for the germicidal lamp 3 to enter and exit the storage cavity 2.1.

[0046] At the same time, 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.

[0047] Specifically, as shown in the appended Figure 1As shown in the figure, a support portion 2.4 is provided on the outer edge of the installation opening 2.3 in a protruding manner. The cover plate 5 is fixedly connected to the support portion 2.4 by a fastener 6 (such as a screw), and the installation opening 2.3 is blocked and covered.

[0048] During assembly, by removing the cover plate 5, the sterilization lamp 3 can be 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 to complete the installation.

[0049] In this embodiment, the cover plate 5 is detachably fixedly connected to the side tube 2 by 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.

[0050] Furthermore, in the above solution, the sterilization lamp 3 can be fixedly connected to the storage cavity 2.1 by structures such as snaps or screws.

[0051] In this embodiment, the sterilization lamp 3 is preferably fixedly connected to the side of the cover plate 5 facing the storage cavity 2.1. On the one hand, this enables the sterilization 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 the need to additionally set up a positioning structure in the narrow space of the storage cavity 2.1.

[0052] Specifically, in this embodiment, the sterilization lamp 3 includes: a mounting post 3.1, a lamp cover 3.2, a lamp tube 3.4, and a power supply structure for supplying power to the lamp tube 3.4.

[0053] Among them, the mounting post 3.1 is fixedly connected to the side of the cover plate 5 facing the storage cavity 2.1 by, 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 sterilization lamp 3 to the cover plate 5. A lamp cover 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 3 As shown, an installation cavity 3.3 that is not connected to the external space is formed at an interval between the lamp cover 3.2 and the end of the mounting post 3.1.

[0054] 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 mounting post 3.1, and the lamp tube 3.4 can be positioned and embedded in the installation groove. At this time, the power supply structure can be: a battery provided in the mounting 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 mounting 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 being exposed. By connecting the exposed end of the power cord to an external power source, power supply to the lamp tube 3.4 is achieved.

[0055] The lamp cover 3.2 is preferably detachably sleeved on the mounting post 3.1 through, for example, a threaded structure to facilitate the maintenance of the lamp tube 3.4.

[0056] At this time, the gasket 7 is sleeved outside the lamp cover 3.2 and can form an elastic seal between the germicidal 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 outwards through the mounting opening 2.3.

[0057] Moreover, during installation, the gasket 7 is first sleeved on the germicidal lamp 3, and then the germicidal lamp 3 and the gasket 7 are inserted into the storage cavity 2.1 together through the mounting opening 2.3.

[0058] As shown in the attached Figure 3 to the attached Figure 4 As shown, on the outer periphery of the gasket 7 near one end of the cover plate 5, there is provided 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 tube 2 to improve the sealing effect between the cover plate 5 and the side tube 2.

[0059] Furthermore, on the side wall of the mounting opening 2.3, there is a clamping groove 2.31 opening towards the cover plate 5; the flange portion 7.1 is fitted into the clamping groove 2.31 to improve the installation stability of the flange portion 7.1 and to form a more stable seal between the cover plate 5 and the side tube 2.

[0060] Based on the above solution, considering that it is found in actual production that when the pipeline assembly is integrally assembled into the gas water heater or when the pipeline assembly is transported and moved in the gas water heater, it is very easy to be impacted or shocked, resulting in the breakage of the germicidal lamp 3. And the fragments generated after the breakage of the germicidal lamp 3 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 pipeline 1 but also easily causes safety accidents when flowing out with the water, which is very dangerous.

[0061] Based on this, as shown in the attached Figure 2 to the attached Figure 4 As shown, 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, and it is located on the side of the germicidal lamp 3 facing the conveying channel 1.1; moreover, a number of light-passing holes 4.1 are provided on the protective cover 4, and 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.

[0062] That is, the protective cover 4 with the light passing hole 4.1 is formed with a mesh cover that prevents the sterilization lamp 3 from falling into the conveying channel 1.1. When the sterilization lamp 3 (as described above, the sterilization 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 by the protective cover 4 in the storage cavity 2.1 to prevent them from falling into the conveying channel 1.1. Moreover, when the sterilization lamp 3 emits ultraviolet rays as described above, the ultraviolet rays can pass through the light passing hole 4.1 to irradiate from the storage cavity 2.1 into the conveying channel 1.1 to sterilize the water flow in the conveying channel 1.1.

[0063] At this time, the caliber of the installation opening 2.3 is set according to the sizes of the sterilization lamp 3 and the protective cover 4 to form an opening for the sterilization lamp 3 and the protective cover 4 to enter and exit the storage cavity 2.1.

[0064] 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 sterilization 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 to complete the installation.

[0065] In order for the sterilization 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 sterilization 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 sterilization 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. Or, the main body part 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.

[0066] Moreover, in order to better accommodate the fragments when the sterilization lamp 3 is broken; as shown in the appendix Figure 3 The protective cover 4 is provided with an object-catching groove 4.2, and the notch of the object-catching groove 4.2 is arranged facing the sterilization lamp 3. After the sterilization 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.

[0067] 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.

[0068] Therefore, the protective cover 4 in this embodiment is preferably installed in the storage cavity 2.1. Moreover, the outer contour dimensions of the protective cover 4 are preferably adapted to the inner wall contour of the storage cavity 2.1, so that when the protective cover 4 is installed in the storage cavity 2.1 as shown in the appendix Figure 4 , the protective cover 4 can be fitted and installed in the storage cavity 2.1 to better prevent the germicidal lamp 3 from falling into the conveying channel 1.1.

[0069] Furthermore, to enable the protective cover 4 to be placed more stably in the storage cavity 2.1, as shown in the appendix Figure 2 to the appendix Figure 4 , a limiting portion 2.2 is convexly provided 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.

[0070] To improve the limiting effect and the positioning stability of the protective cover 4, the limiting portion 2.2 is preferably an annular protrusion provided around the inner wall of the storage cavity 2.1, and the lapping portion 4.3 is an annular flange structure provided around the outer edge of the protective cover 4 and adapted to lap on the annular limiting portion 2.2.

[0071] Embodiment Two:

[0073] The heat exchanger housing 8 has a flue gas flow channel 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 assembly is wound around the outside of the heat exchanger housing 8, or has a part inserted into the heat exchanger housing 8 and placed in the flue gas flow channel. When high-temperature flue gas flows through the flue gas flow channel, the water in the water supply pipeline 1 can exchange heat with the high-temperature flue gas to be heated.
