Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0068] like Figures 1 to 10 As shown, this embodiment provides a shielding cover 1 and a water heater 100 including the shielding cover 1. The shielding cover 1 is used to shield the pipe assembly located below the shell 2 of the water heater 100 along a first direction. In this embodiment, the first direction is the height direction H of the water heater 100. However, it is not limited thereto. In other embodiments, the first direction may also be the length direction L of the water heater 100, which is determined by the specific direction in which the pipe assembly is relatively arranged in the water heater 100.

[0069] The shielding cover 1 includes a shielding body 10 and a magnetic member 20 .

[0070] The shielding body 10 includes a side wall 11, which extends along a first direction and is surrounded by a receiving cavity 12 for receiving a pipeline assembly. An end of the side wall 11 close to the shell 2 of the water heater 100 is provided with a mounting portion 13 extending into the receiving cavity 12. The mounting portion 13 is provided with a mounting groove 131 for receiving a magnetic member 20. The opening 1311 of the mounting groove faces the shell 2, and the magnetic member 20 is exposed at the opening 1311. The magnetic member 20 is attached to and magnetically adsorbed on the shell 2 of the water heater 100, and is used to fix the shielding cover 1 on the shell 2 of the water heater 100. In this embodiment, the side wall 11 extends along the first direction, that is, the side wall 11 extends along the height direction H of the water heater 100.

[0071] In this way, by setting up the shielding cover 1, the exposed pipe components of the water heater 100 can be shielded; further, by setting up a magnetic part 20 that is in contact with and magnetically adsorbed to the shell 2 of the water heater 100, the shielding cover 1 can be fixed to the shell 2, which can ensure the shielding and decorative effects while achieving simple installation.

[0072] A fixing portion 15 is provided on the bottom wall of the mounting groove 131, and a side of the fixing portion 15 away from the bottom wall of the mounting groove 131 is a fixing surface 151, and the fixing surface 151 is a plane, and the magnetic member 20 is fixed to the fixing surface 151 through an adhesive layer. In this way, by setting the fixing surface 151 as a flat fixing portion 15, it can be ensured that the magnetic member 20 remains horizontal and does not tilt after bonding, and the magnetic attraction effect with the housing 2 of the water heater 100 is guaranteed to the greatest extent.

[0073] Furthermore, the fixing part 15 is a frame structure, and a part of the glue layer is accommodated in the hollow area of ​​the frame structure. In this way, by setting the fixing part 15 as a frame structure, the fixing surface 151 of the frame structure has a better flatness than the large plane of the solid structure; and by setting the fixing part 15 as a frame structure, a part of the glue layer is accommodated in the hollow area of ​​the frame structure, ensuring that the glue before solidifying into the glue layer can fall in the center of the frame structure, so that it is gathered by the frame structure, and during the installation of the magnetic part 20, the glue can evenly contact the bottom of the magnetic part 20 and complete the bonding action. Among them, the glue is a commercially available product.

[0074] Specifically, in this embodiment, the fixing portion 15 is a circular frame structure (circular ring). However, it is not limited thereto. In other embodiments, the fixing portion 15 may also be a polygonal frame structure, a rectangular frame structure, an elliptical frame structure, or other structures of other shapes. The height of the fixing portion 15 is 0.5 mm to 1.0 mm, so as to effectively gather the glue while minimizing the influence on the height of the magnetic member 20.

[0075] In this embodiment, the cross-sectional shape of the magnetic member 20 is circular, but not limited thereto, in other embodiments, the cross-sectional shape of the magnetic member 20 may also be polygonal, rectangular, elliptical or other shapes.

[0076] There are multiple magnetic members 20, the mounting grooves 131 correspond to the magnetic members 20 one by one, and the multiple magnetic members 20 are arranged at intervals along the circumference of the accommodating cavity 12. By arranging multiple magnetic members 20 at intervals along the circumference of the accommodating cavity 12, more magnetic positions can be provided, so that the shielding cover 1 can be fixed on the housing 2 more firmly.

[0077] In this embodiment, the number of the magnetic members 20 is nine, but is not limited thereto. In other embodiments, the number may be two, three, four, five or other values.

[0078] The side wall of the mounting groove is provided with a limiting portion 16 protruding inward, and the limiting portion 16 abuts against the magnetic part 20, or the limiting portion 16 and the magnetic part 20 are interference fit. In this way, by providing a limiting portion 16 protruding inward on the side wall of the mounting groove, which abuts against or interferes with the magnetic part 20, the magnetic part 20 can be effectively limited, and the reliability of the connection between the magnetic part 20 and the shielding body is further ensured. The number of limiting portions 16 is several, and when the number of limiting portions 16 is multiple, the multiple limiting portions 16 are arranged at circumferential intervals along the mounting groove 131. In the present embodiment, the number of limiting portions 16 is four, and the four limiting portions 16 are arranged at circumferential intervals along the mounting groove 131. However, it is not limited to this, and in other embodiments, it can also be two, three, five or other values.

[0079] Preferably, the plane where the opening 1311 of the mounting slot is located is the top surface 19 of the shielding body 10, and the end of the magnetic member 20 close to the opening 1311 is flush with the plane where the opening 1311 of the mounting slot is located or protrudes from the plane where the opening 1311 of the mounting slot is located; in this way, since the plane where the opening 1311 of the mounting slot is located is the top surface 19 of the shielding body 10, by setting the end of the magnetic member 20 close to the opening 1311 to be flush with the plane where the opening 1311 of the mounting slot is located or protrudes from the plane where the opening 1311 of the mounting slot is located, that is, the end of the magnetic member 20 close to the opening 1311 is flush with the top surface 19 of the shielding body 10 or protrudes from the top surface 19 of the shielding body 10, the magnetic member 20 can be free from the influence of other structures and better fit with the shell 2.

[0080] The side wall 11 is provided with a first reinforcement part 171 at both ends along the height direction H (first direction), and the first reinforcement part 171 extends along the circumference of the accommodating cavity 12. One end of the first reinforcement part 171 is connected to the inner surface of the side wall 11, and the other end extends into the accommodating cavity 12. The side wall 11 is provided with a second reinforcement part 172 at the middle position along the height direction H (first direction), and the second reinforcement part 172 extends along the circumference of the accommodating cavity 12. One end of the second reinforcement part 172 is connected to the inner surface of the side wall 11, and the other end extends into the accommodating cavity 12. In this way, by providing the first reinforcement part 171 and the first reinforcement part 171, the structural strength and rigidity of the shielding body 10 can be effectively improved.

[0081] The mounting portion 13 is also provided with a plurality of fixing holes 132, and the fixing holes 132 are spaced apart from the mounting grooves 131. The fixing member passes through the fixing hole 132 and is fixedly connected to the shell 2. Specifically, the fixing hole 132 is a screw hole, and the fixing member is a screw. By providing the fixing hole 132, when it is necessary to add a hanging function to the shielding cover 1, if the magnetic attraction strength of the magnetic member 20 is not sufficient to support the weight of the hanging object, the shielding body 10 can be directly locked to the bottom of the shell 2 by screws. This can meet the needs of users while eliminating the risk of users worrying about the shielding cover 1 falling off.

[0082] Preferably, the shielding body 10 is integrally formed. Thus, by setting the shielding body 10 to be integrally formed, the manufacturing process of the shielding body 10 can be simplified while improving the overall structural strength and rigidity of the shielding body 10.

[0083] Please refer to Fig. 9 and Fig.10 The water heater 100 of this embodiment includes a housing 2 and the shielding cover 1 as described above. The housing 2 is configured to be a magnetic material having a different polarity from the magnetic member 20, but is not limited thereto. Alternatively, a magnetic part may be fixedly provided at a position corresponding to the housing 2 and the magnetic member 20, and the magnetic part may have a different polarity from the magnetic member 20.

[0084] In this embodiment, the orthographic projection of the pipe assembly of the water heater 100 along the height direction H (first direction) is located within the orthographic projection of the housing 2, and the orthographic projection of the shielding cover 1 is located within the orthographic projection of the housing 2. In this way, the space occupied by the shielding cover 1 can be effectively saved, and the influence of the shielding cover 1 on the facilities around the water heater 100 can be avoided.

[0085] Further, the orthographic projection of the shielding cover 1 along the height direction H (first direction) matches the shape and size of the orthographic projection of the housing 2. In this embodiment, the shape of the orthographic projection of the housing 2 along the height direction H is a rectangle, and similarly, the shape of the orthographic projection of the shielding cover 1 along the height direction H (first direction) is also a rectangle. However, it is not limited to this, and in other embodiments, the shape of the orthographic projection of the housing 2 along the height direction H (first direction) may also be an ellipse, a polygon, or other shapes.

[0086] Thus, by matching the shape and size of the orthographic projection of the shielding cover 1 and the shell 2 in the height direction H (first direction), the space where the shielding cover 1 is located can be effectively utilized while avoiding the influence of the shielding cover 1 on the facilities around the water heater 100.

[0087] Preferably, the mounting portion 13 of the shielding cover 1 is further provided with a first positioning portion 18 , and the shell 2 is provided with a second positioning portion at a position corresponding to the first positioning portion 18 , and the first positioning portion 18 and the second positioning portion cooperate to limit the relative displacement of the shielding body 10 and the shell 2 .

[0088] In this embodiment, the first positioning portion 18 is a limiting column protruding from the mounting portion 13, and the second positioning portion is a through hole opened on the housing 2. However, it is not limited thereto, and in other embodiments, the first positioning portion 18 may be a through hole opened on the mounting portion 13, and the second positioning portion may be a limiting column protruding from the housing 2.

[0089] In this way, by providing the cooperation between the first positioning portion 18 and the second positioning portion, it is ensured that after installation, the shielding cover 1 and the housing 2 will not have a large slippage, thereby affecting the appearance.

[0090] Preferably, there is a gap between the outer wall of the limiting column and the inner wall of the through hole, so that there can be a certain installation margin between the two during installation. For example, the outer diameter of the limiting column is 3 mm, and the inner diameter of the through hole is 4 mm.

[0091] The outer edges of the shielding body 10 of the shielding cover 1 in this embodiment are all rounded, but are not limited thereto. Fig.11 As shown, in another implementation of the present embodiment, the outer edges of the shielding body 10 of the shielding cover 1 are all right angles. Fig.12 In another implementation of the water heater 100 of the present embodiment, the outer edges of the shielding body 10 of the shielding cover 1 are also right angles.

[0092] In this embodiment, a shielding cover 1 is provided to shield the exposed pipe components of the water heater 100; further, a magnetic member 20 is provided to fit and magnetically adsorb to the shell 2 of the water heater 100 so as to fix the shielding cover 1 to the shell 2, thereby achieving simple installation while ensuring shielding and decorative effects.
