[0010] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art. The terms used in the specification of this application are used only for the purpose of describing certain embodiments and are not intended to limit the present application. The term "and / or" used herein includes any and all combinations of one or more of the associated listed items.

[0011] 1 to 4, the present application provides a piping member 10 for a water heater, which is used to connect with a corresponding joint 20 to realize a pipe connection.

[0012] In the related art, the pipe joint joining method used in the pipe group of the water heater is by welding the copper pipe and the molded joint to each other, and the welded pipe group has a risk of leakage later, and the material cost and labor cost are relatively high. In the processing process, it is necessary to repeat the logistics between the steps, which is relatively time-consuming and labor-intensive.

[0013] 1 to 4, this piping member 10 for a water heater includes a pipe body 11, and one end of the pipe body 11 is provided with an abutment segment 12 that is integrally molded with the pipe body 11 and is for joining to a joint 20. At least two protruding ring portions 121 are provided on the outer wall portion of the abutment segment 12, and a recessed portion 122 capable of accommodating a seal member 30 is formed between two adjacent protruding ring portions 121.

[0014] By integrally molding the pipe body 11 and the abutment segment 12 for joining to the joint 20, it is possible to reduce a series of steps of welding the abutment segment 12 and the pipe body 11 by repeatedly transferring between steps, and it is possible to significantly reduce the processing steps and processing costs. Furthermore, by integrally molding the abutment segment 12 and the pipe body 11, there is no gap between the abutment segment 12 and the pipe body 11, there is no problem of poor welding, and the risk of leakage between them can be eliminated.

[0015] At least two convex ring portions 121 are provided as a first convex ring portion 121a and a second convex ring portion 121b, and the first convex ring portion 121a is disposed closer to the pipe body 11 than the second convex ring portion 121b, and cooperate to regulate the position of the joint 20 and prevent the joint 20 from coming off the abutment segment 12. In addition, a recessed chamber 122 is formed between the first convex ring portion 121a and the second convex ring portion 121b, and the recessed chamber 122 is for accommodating and regulating the position of the seal member 30, and prevents the seal member 30 from shifting or falling off. Of course, in other embodiments, the number of the convex ring portions 121 provided is not limited to the above.

[0016] In one embodiment, referring to Figures 2 to 4, three convex ring portions 121 are provided, namely a first convex ring portion 121a, a second convex ring portion 121b, and a third convex ring portion 121c, in which the first convex ring portion 121a and the second convex ring portion 121b are arranged close to the pipe body 11 and in contact with each other, and the third convex ring portion 121c is arranged away from the pipe body 11 and is arranged at a distance from the first convex ring portion 121a and the second convex ring portion 121b so as to form a recessed portion 122. By the first convex ring portion 121a and the second convex ring portion 121b abutting each other, the positional restriction strength of both with respect to the fitting 20 can be increased. As a result, when the first convex ring portion 121a alone restricts the position, it is possible to avoid the first convex ring portion 121a deforming due to insufficient strength and affecting the sealing property of the positional restriction joint with the fitting 20.

[0017] In another embodiment, as shown in FIG. 1, three convex ring portions 121 are provided, namely a first convex ring portion 121a, a second convex ring portion 121b, and a third convex ring portion 121c, and a first recessed reservoir portion 122a is formed between the adjacent first convex ring portion 121a and the second convex ring portion 121b, and a second recessed reservoir portion 122b is formed between the adjacent second convex ring portion 121b and the third convex ring portion 121c. Here, the first recessed reservoir portion 122a and the second recessed reservoir portion 122b can both be used to accommodate a seal member 30, thereby improving the sealing performance between the joint 20 and the abutting segment 12.

[0018] In one embodiment, the thickness of the convex ring portion 121 along the radial direction of the abutment segment 12 is equal to or greater than the thickness of the tube 11, so that the convex ring portion 121 has sufficient strength, and when the joint 20 and the tube 11 are pulled relatively, if the strength of the convex ring portion 121 is insufficient, the convex ring portion 121 is likely to become inclined, causing a problem in position regulation with respect to the joint 20, and the joint 20 is prevented from coming off the abutment segment 12 and causing leakage. Therefore, it is particularly important to ensure sufficient strength of the convex ring portion 121. Of course, in other embodiments, it is also possible to arrange multiple convex ring portions 121 that abut each other so as to cooperate with each other to provide sufficient position regulation strength, so that there is no need to limit the thickness of the convex ring portion 121 along the radial direction of the abutment segment 12, and the thickness of the convex ring portion 121 may be equal to or greater than the thickness of the tube 11 or may be equal to or less than the thickness of the tube 11.

[0019] In one embodiment, the inner diameter of the abutment segment 12 is made equal to or larger than the inner diameter of the tube 11, so that the liquid flowing out of the tube 11 can flow out smoothly as it passes through the abutment segment 12, thereby avoiding a situation in which the inner diameter of the abutment segment 12 is too small, causing an obstruction to the fluid and affecting the flow rate of the fluid.

[0020] In one embodiment, the convex ring portion 121 is formed by pressing, the pressing method is simple, and the convex ring portion 121 formed by pressing and the abutment segment 12 have an integral structure, which can ensure a relatively high bonding strength between the convex ring portion 121 and the abutment segment 12, effectively preventing the convex ring portion 121 from falling off in the later stage of use. Of course, in other embodiments, the convex ring portion 121 may be formed by processing it using other processing methods, such as integrally forming the abutment segment 12 and the convex ring portion 121 using a mold.

[0021] The tube 11 is made of a copper tube, which has better thermal conductivity, is less likely to deteriorate over time, and has better toughness, making it particularly suitable for use in water heaters. Of course, in other embodiments, the tube 11 may be a stainless steel tube.

[0022] The present application further provides a piping assembly 100. Referring to Fig. 3 and Fig. 4, the piping assembly 100 includes a joint 20, a seal member 30, and the piping member 10 for the water heater in any of the above-mentioned embodiments, in which the joint 20 is fitted onto the abutment segment 12 to realize the joining of the joint 20 and the pipe body 11. The seal member 30 is attached in the recessed portion 122 to realize the sealing of the joint 20 and the abutment segment 12, and is used to prevent internal leakage at the joining portion between the joint 20 and the abutment segment 12.

[0023] 3 and 4, the piping assembly 100 further includes a fixing piece 40, and the fitting 20 has an engaging port 21 that communicates with the inside of the fitting 20, and the fixing piece 40 can be inserted into the engaging port 21. In this way, the fitting 20 is fitted onto the abutment segment 12, and the engaging port 21 is made to correspond to the pipe body 11, and the engaging port 21 is positioned on the side of the convex ring portion 121 closer to the pipe body 11, i.e., the fixing piece 40 is inserted into the engaging port 21 so that the engaging port 21 is positioned on the side of the first convex ring portion 121a closer to the pipe body 11. The fixing piece 40 abuts against the first convex ring portion 121a in cooperation with the first convex ring portion 121a, and the first convex ring portion 121a can restrict the movement of the fixing piece 40 to the abutment segment 12, thereby realizing the regulation of the abutment position between the fitting 20 and the abutment segment 12, and the assembly and joining of the fitting 20 and the pipe body 11 is realized.

[0024] As shown in FIG. 5, the present application further provides a water heater 200 including the above-described piping assembly 100, in which the pipe body 11 and the fitting 20 in the piping assembly 100 are firmly joined, eliminating the risk of leakage in subsequent use, thereby contributing to improving the quality, performance, and extending the lifespan of the heat exchanger.

[0025] The technical features of the above embodiments may be combined in any combination. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, any combination should be considered within the scope of the present specification.

[0026] Those skilled in the art should recognize that the above embodiments are only used to explain the present application, and are not intended to be used to limit the present application, and any suitable modifications and variations of the above embodiments fall within the scope of the present application as long as they are within the substantial spirit of the present application.
