Description

Technical Field

[0001] The utility model belongs to the field of water heater devices, in particular to an anti-deflection external wall hanging bracket used for an electric water heater. Background Art

[0002] Although the existing external wall bracket can bear the load of the hanging machine, it has structural defects because the two screw holes connecting the outer shell are arranged in a horizontal direction. Even after being tightened, the bracket can still deflect to the left or right after being subjected to force. There is a phenomenon that the external wall bracket is tilted relative to the water heater (not horizontal or vertical), which affects the product appearance and the hanging effect, and brings troubles to the after-sales installation. In serious cases, the after-sales personnel need to knock the bracket to vertical before hanging the machine during installation.

[0003] Chinese patent application number CN202321499545.2 discloses a water heater external wall bracket and a water heater, which saves two screws but fails to ensure the verticality of the bracket and the water heater casing.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide an anti-deflection external wall bracket for an electric water heater, which can make the bracket vertically non-deflected relative to the entire shell of the water heater and has higher strength.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0007] The invention discloses an anti-deviation exterior wall bracket for an electric water heater, characterized in that: the bracket is provided with an outer shell connecting part hole and an inner tank bracket connecting part hole, the two outer shell connecting part holes are arranged vertically, and the center connecting line thereof is parallel to the vertical center line of the bracket.

[0008] The hanger is connected to the water heater shell through the shell connector, and is connected to the water heater inner tank bracket through the inner tank bracket connector, so that the hanger is connected to the water heater shell and the inner tank bracket and bears the weight of the water heater shell and the inner tank so that the entire water heater is hung on the wall. In order to enable the hanger and the water heater shell to remain vertical and not deflected when the water heater is hung, in the utility model, two shell connector holes provided on the hanger are arranged vertically and the center line of the two shell connector holes is parallel to the vertical center line of the hanger, so that when the hanger is installed on the shell through the shell connector through the shell connector hole, the hanger and the shell can be kept vertical and not deflected.

[0009] Furthermore, the inner liner support connector holes of the hanger are located between the outer shell connector holes.

[0010] The bracket must also be connected to the inner tank bracket of the water heater through the inner tank bracket connector hole, thereby bearing the weight of the inner tank. In order to enhance the structural stability and strength, the inner tank bracket connector hole of the bracket is located between the two outer shell connector holes of the bracket.

[0011] Furthermore, the hole of the liner support connector is larger than the diameter of the liner support connector, and has a movable margin.

[0012] Since the bracket is to be connected to the inner tank bracket of the water heater, and the inner tank bracket of the water heater may have a certain error and slight deflection during manufacturing and assembly, at this time, if the size of the inner tank bracket connector hole and the inner tank bracket connector are matched without a movable margin, the bracket will be installed on the inner tank bracket of the water heater. It will cause a large assembly stress, causing problems in the connection between the bracket and the water heater shell, and then the bracket will tilt relative to the water heater shell and damage the water heater shell in the later stage. In view of the above problems, in the utility model, the inner tank bracket connector hole is larger than the inner tank bracket connector diameter, and has a movable margin. The "inner liner bracket connector hole is larger than the inner liner bracket connector diameter" mentioned here means that the inner liner bracket connector hole is larger than the diameter of the part of the inner liner bracket connector that penetrates into the inner liner bracket connector hole. In this way, even if there is a certain error and slight deviation in the manufacturing and assembly of the inner liner bracket of the water heater, since the inner liner bracket connector hole is larger than the inner liner bracket connector diameter and has a certain margin of motion, the inner liner bracket connector can be eccentrically connected in the inner liner bracket connector hole, deviating from the latter's center, that is, the two are not assembled concentrically, so as to adapt to the inner liner bracket connector hole and the inner liner bracket connector by adjusting the position, so that the bracket and the water heater casing remain relatively vertical and not deflected.

[0013] Furthermore, an anti-deflection exterior wall bracket used for an electric water heater also includes a hook hole, and the hook hole is located above the hole of the shell connecting piece.

[0014] The bracket is used as an intermediary to hang the water heater on the wall, so a hook hole is provided on the bracket. The hook hole is located above the uppermost shell connector hole. The bracket is hooked on the hook by cooperating with the hook fixed on the wall and the hook hole on the bracket, and then the water heater is hung on the wall.

[0015] Furthermore, the bracket is a stepped structure, and the portion where the outer shell connector hole and the liner bracket connector hole are located and the portion where the hook hole is located are respectively located on two step surfaces.

[0016] In order to avoid the hook from contacting with the water heater shell when the hanger is hooked on the hook, thereby causing damage to the water heater shell and hindering the hook from being hooked, in the utility model, the hanger is a stepped structure, and the portion where the shell connector hole and the inner tank bracket connector hole are located and the portion where the hook hole is located are located are located on two step surfaces respectively. By utilizing the stepped structure of the hanger, after the hanger is connected to the water heater shell, the portion where the shell connector hole and the inner tank bracket connector hole are located on the hanger and the portion where the hook hole is located are not on the same vertical plane, that is, the distances between the two portions and the water heater shell are different, the portion where the shell connector hole and the inner tank bracket connector hole are located are closely attached to the water heater shell, and the portion where the hook hole is located is far away from the water heater shell, thereby leaving space for the hook to penetrate into the hook hole on the hanger to achieve the hook and the hanger hooking, and a larger space can be reserved to ensure that the hook does not contact the water heater shell and is more convenient for the hook and the hanger to be hooked and installed.

[0017] Furthermore, the rack has a step formed by a first groove, and the shell connector hole and the liner bracket connector hole are located at the bottom of the first groove.

[0018] As mentioned above, the rack has a stepped structure. In order to realize this structure and reduce the weight of the rack and enhance the strength of the rack at the same time, a step formed by a first groove is provided on the rack, and the shell connector hole and the inner tank bracket connector hole are located at the bottom of the first groove. Since the stepped structure is formed by the groove, the groove wall can still provide connection, thereby enhancing the overall strength of the rack. Compared with a stepped structure formed by a flat metal part bent into a Z shape, its strength is higher, thereby improving the safety of water heater installation.

[0019] Furthermore, the hanger has a step formed by a second groove, the depth of the second groove is smaller than that of the first groove, and the hook hole is located at the bottom of the second groove.

[0020] Furthermore, the hook hole has flanges around it.

[0021] In order to improve the connection strength of the hook hole on the hanger, flanges are provided around the hook hole, thereby increasing the contact area between the hanger and the hook and improving the strength of the hook hole.

[0022] Furthermore, the center lines of the outer shell connector hole, the liner bracket connector hole and the hook hole are located on the same vertical straight line.

[0023] Furthermore, there is an inclined transition between the two step surfaces.

[0024] The hanger is a step structure, and there is an inclined transition between the two step surfaces. The two step surfaces are connected by the inclined transition, and the connection of the groove wall is enhanced to enhance the overall strength of the hanger.

[0025] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art.

[0026] The utility model discloses an anti-deflection external wall hanger for an electric water heater, wherein the hanger is provided with a shell connecting member hole and an inner tank bracket connecting member hole, wherein the two shell connecting member holes are arranged vertically, and the center connecting line thereof is parallel to the vertical center line of the hanger. By utilizing the principle that two points of the two vertically arranged shell connecting member holes determine a straight line, the center connecting line of the two shell connecting member holes is parallel to the vertical center line of the hanger, thereby realizing that the hanger is always vertically non-deflected relative to the whole machine shell and the hanger strength can be improved.

[0038] Combination Figures 1 to 4 As shown, the utility model is an anti-deflection exterior wall bracket for an electric water heater, the bracket 1 is provided with a shell connecting piece hole 6 and an inner tank bracket connecting piece hole 5, the two shell connecting piece holes 6 are arranged vertically, and the center connection line thereof is parallel to the vertical center line of the bracket 1.

[0039] The inner liner support connector hole 5 of the rack 1 is located between the two outer shell connector holes 6 .

[0040] The inner liner support connecting piece hole 5 is larger than the inner liner support connecting piece in diameter, and there is a movable margin between the two.

[0041] The bracket 1 is connected to the water heater shell 3 through the shell connector, and is connected to the water heater inner tank bracket 4 through the inner tank bracket connector, so that the bracket 1 is connected to the water heater shell 3 and the inner tank bracket 4 and bears the weight of the water heater shell 3 and the inner tank 2 so that the entire water heater can be hung on the wall.

[0042] In order to enable the bracket 1 and the water heater shell 3 to remain vertical and not skewed when the water heater is hung, in the utility model, the two shell connecting member holes 6 provided on the bracket 1 are arranged vertically and the center line of the two shell connecting member holes 6 is parallel to the vertical center line of the bracket 1, so that when the bracket 1 is installed on the shell 3 by passing the shell connecting member through the shell connecting member hole 6, the bracket 1 and the shell 3 can be kept vertical and not skewed.

[0043] In the embodiment, the screw 61 as the housing connecting member is inserted into the housing connecting member hole 6 to install the bracket 1 on the housing 3 .

[0044] The bracket 1 also needs to be connected to the inner tank bracket 4 of the water heater through the inner tank bracket connector hole 5 to bear the weight of the inner tank 2. In order to increase the structural stability and strength, the inner tank bracket connector hole 5 of the bracket 1 is located between the two outer shell connector holes 6 of the bracket 1.

[0045] Since the bracket 1 is to be connected to the inner tank bracket 4 of the water heater, and the inner tank bracket 4 of the water heater may have a certain error and slight deflection during manufacturing and assembly, at this time, if the size of the inner tank bracket connector hole 5 and the inner tank bracket connector are matched without a movable margin, the bracket 1 will be installed on the inner tank bracket 4 of the water heater. It will cause a large assembly stress, causing problems in the connection between the bracket 1 and the water heater shell 3, and then the bracket 1 will tilt relative to the water heater shell 3 and damage the water heater shell 3 in the later stage. In view of the above problems, in the utility model, the inner tank bracket connector hole 5 is larger than the inner tank bracket connector diameter and has a movable margin. The inner tank bracket connector hole 5 mentioned here is larger than the inner tank bracket connector diameter, which means that the inner tank bracket connector hole 5 is larger than the diameter of the portion of the inner tank bracket connector that penetrates into the inner tank bracket connector hole 5. In this way, even if the inner tank bracket 4 of the water heater has a certain error and slight deflection during manufacturing and assembly, the utility model is an anti-deflection exterior wall bracket used for an electric water heater. During installation, the screw 61 as the outer shell connector is first fixed, and then the bolt 51 as the inner tank bracket connector is fixed. The principle of a straight line is determined by two screws 61 at two points, and at the same time, the inner tank bracket connector hole 5 on the bracket 1 is enlarged to reserve an assembly welding allowance for the welding of the inner tank bracket 4. That is, if the inner tank bracket 4 is slightly deflected, the bolt 51 can be fixed as long as it is within the design allowance of the bracket 1. Since the inner liner bracket connector hole 5 is larger than the inner liner bracket connector diameter, there is a certain amount of free space between the two. The inner liner bracket connector can be eccentrically connected in the inner liner bracket connector hole 5, deviating from the latter's center, that is, the two are not assembled concentrically, so the position adjustment of the inner liner bracket connector hole 5 and the inner liner bracket connector is used to adapt to each other, so that the bracket 1 and the water heater housing 3 remain relatively vertical and not tilted.

[0046] In this embodiment, the bolt 51 as the inner tank support connector is inserted into the inner tank support connector hole 5 to install the hanger 1 on the inner tank support 4 of the water heater. The inner tank support connector hole 5 is larger than the inner tank support connector diameter, which means that the diameter of the inner tank support connector hole 5 is larger than the thread outer diameter of the bolt 51, but the diameter of the inner tank support connector hole 5 is smaller than the nut diameter of the bolt 51, so as to avoid the bolt 51 being unable to connect to the hanger 1.

[0047] The anti-deflection external wall hanger used for the electric water heater of the utility model further comprises a hook hole 7, and the hook hole 7 is located above the hole 6 of the shell connecting piece.

[0048] The bracket 1 is used as an intermediary to hang the water heater on the wall, so a hook hole 7 is provided on the bracket 1, and the hook hole 7 is located above the uppermost shell connecting part hole 6. The bracket 1 is hooked on the hook by using the hook fixed on the wall and the hook hole 7 on the bracket 1, and then the water heater is hung on the wall.

[0049] The center lines of the outer shell connector hole 6, the liner bracket connector hole 5 and the hook hole 7 are located on the same vertical straight line.

[0050] This arrangement is intended to maximize the strength and balance of the hanger 1 when subjected to external forces. The force application points of the inner liner bracket 4, the outer shell 3 and the hook hole 7 on the hanger 1 are located on the same vertical line. In this way, the hanger 1 is stable in withstanding external forces, and the hanger 1 has higher stability and is not prone to rotation and tilting.

[0051] In the utility model, the hanger 1 is a stepped structure, and the hanger part where the shell connector hole 6 and the liner bracket connector hole 5 are located and the hanger part where the hook hole 7 is located are respectively located on two step surfaces.

[0052] In order to avoid the hook from contacting with the water heater shell 3 when the hanger 1 is hooked on the hook, thereby causing damage to the water heater shell 3 and hindering the hook from being hooked, in the utility model, the hanger 1 is a stepped structure, and the portion where the shell connector hole 6 and the inner tank bracket connector hole 5 are located and the portion where the hook hole 7 is located are located are located on two step surfaces respectively. By utilizing the stepped structure of the hanger 1, after the hanger 1 is connected to the water heater shell 3, the portion where the shell connector hole 6 and the inner tank bracket connector hole 5 are located on the hanger 1 and the portion where the hook hole 7 is located are not on the same vertical plane, that is, the distances between the two portions and the water heater shell 3 are different, the portion of the hanger where the shell connector hole 6 and the inner tank bracket connector hole 5 are located is in close contact with the water heater shell 3, and the portion of the hanger where the hook hole 7 is located is away from the water heater shell 3, so that space can be reserved for the hook to penetrate into the hook hole 7 on the hanger 1 to achieve the hook and the hanger 1 hooking, and a larger space can be reserved to ensure that the hook does not contact the water heater shell 3 and it is more convenient to hook and hang the hanger 1 to install.

[0053] As mentioned above, the rack 1 is a stepped structure. In this embodiment, in order to realize this structure and reduce the weight of the rack 1 and enhance the strength of the rack 1 at the same time, a step formed by a first groove is provided on the rack 1, and the shell connector hole 6 and the liner bracket connector hole 5 are located at the bottom of the first groove. Since the stepped structure is formed by the groove, the groove wall can still provide connection, thereby enhancing the overall strength of the rack 1. Compared with the stepped structure formed by a flat metal part bent into a Z shape, its strength is higher, thereby improving the safety of the water heater installation.

[0054] The hanger 1 also has a step formed by a second groove, the depth of the second groove is smaller than that of the first groove, and the hook hole 7 is located at the bottom of the second groove.

[0055] The setting of the second groove makes the part of the hanger where the hook hole 7 is located also have greater strength. Since the groove wall acts as a reinforcing rib, the step formed by the second groove can further improve the ability of the hanger 1 to withstand external forces. The hanger 1 can withstand greater external forces without the need for overall entity thickening, thereby ensuring the safety of the water heater suspension.

[0056] In order to further improve the connection strength of the hook hole 7 on the hanger 1 , flanges are provided around the hook hole 7 , thereby increasing the contact area between the hanger 1 and the hook and improving the strength of the hook hole 7 .

[0057] The rack 1 is a step structure, and a slope transition is formed between two step surfaces. The slope transition connects the two step surfaces and the groove wall, thereby enhancing the overall strength of the rack 1.
