[0046] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0047] See also Figures 1 to 12The embodiment of the utility model provides a water heater, including a shell 100, an inner tank 200 and a water heater mounting structure, wherein the inner tank 200 is arranged in the shell 100, and there is a gap between the inner tank 200 and the shell 100, and the water heater mounting structure includes an external wall bracket 10 and an inner tank bracket 20, wherein the external wall bracket 10 is arranged on the outside of the shell 100 of the water heater, and the inner tank bracket 20 is arranged on the inside of the shell 100 and connected to the inner tank 200 of the water heater. Usually, the inner tank bracket 20 is welded to the inner tank 200.

[0048] The water heater installation structure also includes a fastening assembly, which is used to fasten the external wall bracket 10, the outer shell 100 and the inner tank bracket 20. The outer shell 100 is provided with a first locking hole 101, and the external wall bracket 10 is provided with a second locking hole 11, and at least one of the first locking hole 101 and the second locking hole 11 is a long hole; the fastening assembly includes a first fastener 31 and a second fastener 32, the first fastener 31 connects the external wall bracket 10, the outer shell 100 and the inner tank bracket 20, and the second fastener 32 is penetrated through the first locking hole 101 and the second locking hole 11 to lock the external wall bracket 10 and the outer shell 100.

[0049] During installation, first use the first fastener 31 to connect the external wall bracket 10, the outer shell 100 and the inner shell bracket 20, and then drive the second fastener 32 into the first locking hole 101 and the second locking hole 11. Since at least one of the first locking hole 101 and the second locking hole 11 is a long hole, it is convenient to adjust the position of the external wall bracket 10 to prevent the external wall bracket 10 from tilting relative to the outer shell 100, thereby improving the installation quality and efficiency.

[0050] In this embodiment, the first fastener 31 is a bolt, and the second fastener 32 is a screw. The connection between the external wall hanger 10, the inner liner bracket 20, the outer shell 100 and the inner liner 200 can be realized by cooperating with one bolt and one screw, and the structure is simple and easy to assemble. Moreover, the length of the external wall hanger 10 can be reduced.

[0051] In some embodiments, the first locking hole 101 can be set as an elongated hole, and the second locking hole 11 can be set as a round hole; or the first locking hole 101 can be set as a round hole, and the second locking hole 11 can be set as an elongated hole.

[0052] In this embodiment, the first locking hole 101 and the second locking hole 11 are both long holes, and the first locking hole 101 and the second locking hole 11 are arranged in a cross. It is convenient to adjust the position of the external wall bracket to ensure that the external wall bracket does not tilt. When adjusting, the first fastener 31 can be not completely locked, and then the external wall bracket can be rotated slightly. When the external wall bracket does not tilt, the first fastener 31 is tightened and the second fastener 32 is driven in.

[0053] When the first locking hole 101 is an elongated hole, the first locking hole 101 may extend parallel to the axis of the housing 100, or the first locking hole 101 may extend in an arc shape around the circumference of the housing 100, or the first locking hole 101 may extend in an arc shape with the axis of the first fastener 31 as the center line. When the second locking hole 11 is an elongated hole, the second locking hole 11 may extend along the length direction of the external wall hanger 10, or the second locking hole 11 may extend along the width direction of the external wall hanger 10. It is worth noting that when the first locking hole 101 and the second locking hole 11 are both elongated holes, the first locking hole 101 and the second locking hole 11 are preferably arranged at an angle.

[0054] It can be understood that the second fastener 32 is a screw, which is driven into the first locking hole 101 and the second locking hole 11. In order to achieve the fastening effect, if the first locking hole 101 and / or the second locking hole 11 is an elongated hole, the width of the elongated hole is smaller than the diameter of the second fastener 32; if the first locking hole 101 or the second locking hole 11 is a round hole, the diameter of the round hole is smaller than the diameter of the second fastener 32.

[0055] In this embodiment, a avoidance hole 222 is formed on the inner container support 20 at a position directly opposite to the second fastener 32 to prevent interference with the insertion of the second fastener 32 .

[0056] The external wall bracket 10 is provided with a first mounting hole 12, the housing 100 is provided with a second mounting hole 102, the inner liner bracket 20 is provided with a threaded hole 223, and the first fastener 31 is passed through the first mounting hole 12 and the second mounting hole 102 and is threadedly connected with the threaded hole 223. The first mounting hole 12 and the second mounting hole 102 are both round holes.

[0057] See also Figures 9 to 12 The inner liner support 20 includes a detachable connector 21 and an insulating member 22. The outer side of the insulating member 22 abuts against the outer shell 100. The connector 21 is arranged on the inner side of the insulating member 22 and connected to the inner liner 200. The inner side of the insulating member 22 forms a contact portion 221, and the contact portion 221 abuts against the inner liner 200. The connector 21 and the insulating member 22 cooperate to provide stable support for the inner liner 200 on the one hand; on the other hand, they have insulation and heat insulation effects, can avoid leakage at the outer shell 100, prevent more heat from being transferred from the inner liner 200 to the outer shell 100, and improve the heat preservation effect of the inner liner 200.

[0058] The contact part 221 is spaced from the connecting part 21. The first fastener 31 connects the insulating part 22 and the connecting part 21, and the second fastener 32 is arranged opposite to the contact part 221. After the external wall hanging bracket 10 is connected to the inner tank bracket 20, the connection position between the outer shell 100 and the second fastener 32 bears a large tensile force. By arranging the second fastener 32 opposite to the contact part 221, the tensile force is transmitted to the contact part 221, avoiding damage to the outer shell 100 due to excessive local stress.

[0059] The contact part 221 is made of insulating material. Preferably, the contact part 221 has a certain elasticity and will generate a certain deformation when stressed. On the one hand, it can form a more sufficient contact with the inner tank 200, and on the other hand, it provides a better supporting effect. Preferably, the surface of the contact part 221 that fits the inner tank 200 is an arc surface to increase the contact area.

[0060] In this embodiment, the contact part 221 includes a plurality of rib plates. Each rib plate is spaced along the first straight line direction, and adjacent rib plates are connected by a reinforcing plate, which can effectively reduce the use of materials and save costs while providing support force.

[0061] In this embodiment, the connecting part 21 is in a "U" shape. The connecting part 21 includes a supporting part 211, connecting arms 212 and a supporting part 213. The two connecting arms 212 are arranged at both ends of the supporting part 211, and a supporting part 213 is arranged on each connecting arm 212. The supporting part 211 is connected to the insulating part 22, and the supporting part 213 is connected to the inner tank 200.

[0062] Since the inner tank 200 of the water heater generally has a large capacity and a large weight after being filled with water, a relatively high strength requirement is imposed on the inner tank bracket 20. On the one hand, the strength of the inner tank bracket 20 itself needs to be considered, and on the other hand, the connection strength between the inner tank bracket 20 and the inner tank 200 also needs to be considered. Therefore, the connecting frame is usually welded to the outer surface of the inner tank 200 to provide a more stable connection. The connecting part 21 is made of metal material, which is resistant to high temperature and has high strength, and has a lower cost in terms of economy. Further, the overall structure of the connecting part 21 can be formed by welding multiple plates, or can be formed by bending a single plate by sheet metal working.

[0063] Further, since the inner tank 200 is generally a cylinder and its surface is an arc, in order to ensure that the supporting part 213 is in close contact with the outer surface of the inner tank 200, the supporting part 213 is preferably arranged as an arc structure having the same radian as the outer surface of the inner tank 200.

[0064] The connecting member 21 is engaged with the insulating member 22 to ensure that the relative positions of the two are fixed, so as to facilitate the installation of the first fastener 31. Specifically, the insulating member 22 is provided with a mounting groove 224, and the connecting member 21 is inserted into the mounting groove 224 along a straight line direction, and the insertion direction of the connecting member 21 is parallel to the axis of the liner 200. A buckle 225 is provided on at least one side of the mounting groove 224, and the connecting member 21 is engaged with the buckle 225.

[0065] More specifically, the supporting portion 211 of the connecting member 21 is inserted into the mounting groove 224 , and the two connecting arms 212 of the connecting member 21 are distributed on the upper and lower sides of the mounting groove 224 . Buckles 225 are provided on the upper and lower sides of the mounting groove 224 , and the connecting arms 212 are snap-connected with the buckles 225 , and the first fastener 31 is passed through the supporting portion 211 .

[0066] When the connecting piece 21 is inserted into the installation slot 224, the two connecting arms 212 will squeeze the buckle 225 to deform toward the inner side of the two connecting arms 212, so as to facilitate smooth insertion into the installation slot 224. After the connecting piece 21 is inserted into the installation slot 224, the buckle 225 restores its deformation and abuts against the outer side of the connecting arm 212, so as to prevent the connecting piece 21 from falling out of the installation slot 224.

[0067] It can be understood that the first fastener 31 passes through the connecting member 21, and holes are provided on the opposite side walls of the mounting groove 224 of the insulating member 22. The first hole is provided as a through hole on the side close to the external wall hanger 10, and the second hole is provided as a threaded hole 223 on the side away from the external wall hanger 10. When installing the first fastener 31, the first fastener 31 passes through the external wall hanger 10, the housing 100, the first hole of the insulating member 22, and the connecting member 21 in sequence, and is threadedly connected with the second hole of the insulating member 22.

[0068] Typically, the water heater installation structure includes two external wall brackets 10, and correspondingly, two inner tank brackets 20 are provided to ensure that the water heater is subjected to balanced force.

For the sake of simplicity, only the differences between Embodiment 2 and Embodiment 1 are described. The difference is that a limiting groove 103 is provided on the outer surface of the housing 100, and the external wall hanger 10 is located in the limiting groove 103. The limiting groove 103 serves to limit the external wall hanger 10, facilitating accurate installation of the external wall hanger 10 to prevent the external wall hanger 10 from tilting relative to the housing 100. During installation, the external wall hanger 10 is inserted into the limiting groove 103, and then the first fastener 31 and the second fastener 32 are installed.

[0071] In this embodiment, two limiting ribs 104 are arranged on the outer surface of the housing 100 at intervals, and a limiting groove 103 is formed between the two limiting ribs 104. The limiting rib 104 and the housing 100 can be integrally formed to facilitate processing and production. In other embodiments, the outer surface of the housing 100 can be arranged to be recessed inward to form the limiting groove 103.
