[0044] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0045] Implementation Method 1

[0046] Please refer to Figure 1 and Figure 5 As shown, an electric water heater mounting structure is provided in an embodiment of the utility model, and the electric water heater mounting structure includes an external mounting bracket 100, an internal mounting bracket 200, a fastener 300 and an anti-rotation structure, wherein the internal mounting bracket 200 is fixedly connected to the inner tank 10 of the electric water heater; the fastener 300 is detachably connected to the external mounting bracket 100, the outer shell 20 of the electric water heater and the inner mounting bracket 200, and a heat insulating support member 400 is provided between the fastener 300 and the inner mounting bracket 200; the anti-rotation structure is arranged between the external mounting bracket 100 and the outer shell 20 of the electric water heater, and the anti-rotation structure can limit the external mounting bracket 100 along the circumference of the fastener 300.

[0047] On the whole, when the electric water heater mounting structure is used, the outer bracket 100 and the inner bracket 200 are respectively arranged on both sides of the outer shell 20 of the electric water heater, and the inner bracket 200 can be fixedly connected with the inner tank 10 of the electric water heater. In addition, the outer bracket 100, the outer shell 20 of the electric water heater and the inner bracket 200 are connected by fasteners 300 to play a fixing role, and then the electric water heater is quickly mounted on a supporting structure such as a wall through the outer bracket 100, which has better installation efficiency. In addition, an anti-rotation structure is provided between the outer bracket 100 and the electric water heater, and the anti-rotation structure can limit the outer bracket 100 along the circumference of the fastener 300 to prevent the outer bracket 100 from rotating between the outer shell 20 of the electric water heater during the installation process, thereby affecting the installation efficiency.

[0048] The anti-rotation structure in the utility model is arranged between the external bracket 100 and the electric water heater, and no additional anti-rotation bolts are required, thereby reducing the number of parts and reducing the installation cost. Moreover, when the external bracket 100 and the housing 20 of the electric water heater are assembled, the anti-rotation structure can be formed synchronously, and no additional steps are required to install the anti-rotation structure, thereby helping to reduce the installation steps and improve the installation efficiency.

[0049] The utility model improves the structural stability of the external bracket 100 on the electric water heater through the anti-rotation structure, so that the external bracket 100 can be arranged according to a preset target, and the electric water heater can be installed more accurately at the target position, thereby improving the installation quality of the electric water heater.

[0050] In the implementation mode of the present utility model, Figure 1 , Figure 2 , Figure 3 and Figure 4 In the illustrated embodiment, a first mounting hole 110 is provided on the external bracket 100, a second mounting hole 21 is provided on the outer shell 20, and the fastener 300 is inserted into the first mounting hole 110 and the second mounting hole 21; a gasket 500 is sleeved on the fastener 300, and at least part of the gasket 500 is inserted into the first mounting hole 110 and the second mounting hole 21.

[0051] Specifically, Figure 4 and Figure 5 In the embodiment shown, the fastener 300 is inserted into the first mounting hole 110 and the second mounting hole 21, and is connected to the inner bracket 200 disposed in the outer shell 20 of the electric water heater, so that the fastener 300 can play a fixing role, thereby improving the structural stability between the outer bracket 100, the outer shell 20 and the inner bracket 200.

[0052] Furthermore, in order to prevent the heat on the inner liner 10 from being transferred to the outer rack 100 along the fastener 300, a heat insulating support 400 is provided between the fastener 300 and the inner rack 200. The heat insulating support 400 can play a certain supporting role between the fastener 300 and the inner rack 200 and isolate the heat on the inner liner 10 and the inner rack 200.

[0053] In the implementation mode of the present utility model, Figure 6 In the embodiment shown, the heat insulating support member 400 is formed by an insulating material. Preferably, the heat insulating support member 400 is formed by a rubber material, and the rubber heat insulating support gasket can play a heat insulating role, thereby preventing the fastener 300 from transferring heat from the inner rack 200 and the liner 10 to the outer rack 100.

[0054] Of course, designers can adjust the specific structure and material of the thermal insulation support member 400 according to usage requirements, such as using materials such as plastic or ceramic, and no specific restrictions are made here.

[0055] In a feasible implementation of the present utility model, if Figure 4 In the illustrated embodiment, the anti-rotation structure includes an anti-rotation portion 111 protruding from the edge of the first mounting hole 110 , and an anti-rotation groove 211 disposed at the edge of the second mounting hole 21 , and the anti-rotation portion 111 is inserted into the anti-rotation groove 211 .

[0056] By providing an anti-rotation portion 111 on the external bracket 100 and an anti-rotation groove 211 on the outer shell 20, when the external bracket is fixedly connected to the outer shell 20 via the fastener 300, the anti-rotation portion 111 can be inserted into the anti-rotation groove 211 to prevent rotation, thereby eliminating the need for additional anti-rotation bolts and adding additional installation steps, thereby significantly improving the structural stability of the external bracket 100.

[0057] The designer can adjust the specific shape of the anti-rotation portion 111 and the anti-rotation groove 211 according to the use requirements, and no specific limitation is made here. Preferably, the shapes of the anti-rotation portion 111 and the anti-rotation groove 211 are roughly matched, which helps to reduce or eliminate the installation gap between the anti-rotation portion 111 and the anti-rotation groove 211, thereby helping to improve the anti-rotation effect.

[0058] In an embodiment of the present invention, a plurality of anti-rotation parts 111 are provided, and the plurality of anti-rotation parts 111 are arranged at intervals around the edge of the first mounting hole 110 , and the anti-rotation grooves 211 are provided corresponding to the anti-rotation parts 111 .

[0059] By providing a plurality of anti-rotation parts 111 , the plurality of anti-rotation parts 111 can cooperate with each other to play a multi-point limiting role, thereby significantly improving the anti-rotation effect.

[0060] Furthermore, by providing a plurality of anti-rotation parts 111, each anti-rotation part 111 can bear the effect of the rotation torque together, thereby reducing the risk of the anti-rotation part 111 being accidentally broken by the rotation torque, and improving the reliability of the anti-rotation structure. The designer can adjust the number and position of the anti-rotation part 111 according to the use requirements, and no specific limitation is made here.

[0061] Preferably, Figure 5 In the embodiment shown, two anti-rotation parts 111 are provided, and the two anti-rotation parts 111 are symmetrically arranged on the edge of the first mounting hole 110 along the extension direction of the external bracket 100, and the distance between the anti-rotation parts 111 on the same side and the side edge of the external bracket 100 is not less than a first preset value.

[0062] By controlling the setting position of the anti-rotation part 111, the distance between the anti-rotation part 111 and the side edge of the external rack 100 is not less than the first preset value, so that sufficient frame can be reserved on the side edge of the external rack 100 to meet the support needs, and the anti-rotation part 111 is prevented from excessively encroaching on the external rack 100 and affecting the structural strength of the external rack 100. The designer can adjust the size of the first preset value according to the use needs, and no specific numerical limit is made here.

[0063] In the implementation mode of the present utility model, Figure 3In the embodiment shown, at least part of the external rack 100 is folded toward the housing 20 to form the anti-rotation portion 111. By folding part of the external rack 100 to form the anti-rotation portion 111, no additional parts are required, which reduces the manufacturing difficulty and cost. In addition, the folding processing method has higher processing efficiency, so that it is easy to quickly process the external rack 100 to form the anti-rotation portion 111.

[0064] In one possible embodiment, if Figure 2 and Figure 3 In the illustrated embodiment, the external mounting bracket 100 includes an external mounting plate, and a first mounting hole 110 is provided on the external mounting plate.

[0065] A roughly rectangular anti-rotation portion 111 is formed by die-cutting the side edge of the first mounting hole 110 , and the anti-rotation portion 111 is folded toward the housing 20 so that the anti-rotation portion 111 is roughly perpendicular to the external plate, thereby facilitating the anti-rotation portion 111 to be inserted into the anti-rotation groove 211 .

[0066] During installation, when the external bracket 100 is connected to the outer shell 20 through the fastener 300, the external bracket 100 can simultaneously drive the anti-rotation part 111 to be inserted into the corresponding anti-rotation groove 211 to play an anti-rotation role, so that through one installation operation, the connection between the external bracket 100 and the outer shell 20 is realized, and the connection between the anti-rotation part 111 and the anti-rotation groove 211 is also realized, which reduces the installation steps and improves the installation efficiency.

[0067] Of course, in other feasible embodiments, designers can adjust the folding direction and specific structure of the anti-rotation portion 111 according to usage requirements, and no specific limitation is made here.

[0068] In order to make the anti-rotation part 111 better cooperate with the anti-rotation groove 211 and prevent the anti-rotation part 111 from accidentally detaching from the anti-rotation groove 211, the setting length of the anti-rotation part 111 needs to be greater than the depth of the anti-rotation groove 211, so that part of the anti-rotation part 111 will pass through the anti-rotation groove 211, but this part of the anti-rotation part 111 is easy to interfere with the thermal insulation support 400 in the outer shell 20.

[0069] In order to solve the above problems, in the implementation mode of the present utility model, Figure 6 In the illustrated embodiment, a first avoidance groove 410 facing the housing 20 is provided on the heat insulating support member 400 , and at least a portion of the anti-rotation portion 111 passes through the anti-rotation groove 211 and is inserted into the first avoidance groove 410 .

[0070] By setting a first avoidance groove 410 on the insulation support 400, the front end of the anti-rotation part 111 can be inserted into the first avoidance groove 410 to play a role of accommodation and limitation, thereby preventing the anti-rotation part 111 from directly abutting against the insulation support 400 and affecting the installation effect.

[0071] When there are multiple anti-rotation parts 111 , the first avoidance grooves 410 are arranged one-to-one with the anti-rotation parts 111 , so that the front end of each anti-rotation part 111 can be inserted into the first avoidance grooves 410 , thereby improving the adaptability of the thermal insulation support member 400 .

[0072] The designer can adjust the specific structure of the first avoidance groove 410 according to the use requirements, and no specific limitation is made here. Preferably, the front end of the first avoidance groove 410 and the anti-rotation part 111 are substantially configured to have the same shape, thereby helping to reduce or eliminate the installation gap between the first avoidance groove 410 and the anti-rotation part 111, thereby improving the accommodation effect.

[0073] Furthermore, the distance between the anti-rotation portion 111 and the side edge of the heat insulating support 400 on the same side is not less than the second preset value. By making the distance between the anti-rotation portion 111 and the side edge of the heat insulating support 400 not less than the second preset value, sufficient body can be reserved on the side edge of the heat insulating support 400 to meet the support needs, thereby avoiding the first avoidance groove 410 from excessively encroaching on the heat insulating support 400 and affecting the structural strength of the heat insulating support 400.

[0074] In another feasible implementation of the present utility model, as Figure 7 , Figure 8 and Fig. 9 In the embodiment shown, the first mounting hole 110 is a polygon, the second mounting hole 21 is a polygon, a third mounting hole is provided on the gasket 500, the gasket 500 is sleeved on the fastener 300 through the third mounting hole, and the anti-rotation structure includes an axial limiting portion 510 and a circumferential limiting portion 520 provided on the gasket 500, the axial limiting portion 510 can abut against the outer wall of the external bracket 100, and the circumferential limiting portion 520 can be inserted into the first mounting hole 110 and the second mounting hole 21.

[0075] By setting the first mounting hole 110 to a polygon and setting the second mounting hole 21 to a polygon, when the circumferential limiting portion 520 of the gasket 500 is inserted into the first mounting hole 110 and the second mounting hole 21, the circumferential limiting portion 520 can play a circumferential limiting role, thereby preventing rotation between the external bracket 100 and the outer shell 20.

[0076] And, if Figure 8 In the illustrated embodiment, the axial limiting portion 510 of the gasket 500 can abut against the outer wall of the external bracket 100 , thereby playing an axial limiting role, so that the circumferential limiting portion 520 can be stably inserted into the first mounting hole 110 and the second mounting hole 21 .

[0077] Designers can adjust the specific shape structures of the first mounting hole 110 and the second mounting hole 21 according to usage requirements. For example, the cross-sectional shape of the first mounting hole 110 can be set to a triangle, a quadrilateral or a larger polygon, and the cross-sectional shape of the second mounting hole 21 can be set to a triangle, a quadrilateral or a larger polygon. No specific restrictions are made here.

[0078] In the embodiment of the present utility model, the cross sections of the first mounting hole 110 , the second mounting hole 21 and the circumferential limiting portion 520 are arranged in the same shape.

[0079] When the circumferential limiting portion 520 and the first mounting hole 110 are in the plugged state, the portion of the circumferential limiting portion 520 that cooperates with the first mounting hole 110 is set to the same shape as the first mounting hole 110, which helps to reduce or eliminate the installation gap between the circumferential limiting portion 520 and the first mounting hole 110, thereby improving the circumferential limiting effect between the circumferential limiting portion 520 and the external bracket 100.

[0080] Furthermore, when the circumferential limiting portion 520 and the second mounting hole 21 are in the plugged state, the portion of the circumferential limiting portion 520 that cooperates with the second mounting hole 21 is set to the same shape as the second mounting hole 21, which helps to reduce or eliminate the installation gap between the circumferential limiting portion 520 and the second mounting hole 21, thereby improving the circumferential limiting effect between the circumferential limiting portion 520 and the outer shell 20.

[0081] By setting the cross-sections of the first mounting hole 110, the second mounting hole 21 and the circumferential limiter 520 to be of the same shape, it is also helpful to reduce the difficulty of processing and manufacturing. Preferably, the cross-sections of the first mounting hole 110, the second mounting hole 21 and the circumferential limiter are all set to be quadrilateral.

[0082] Of course, in other feasible embodiments, the first mounting hole 110 and the second mounting hole 21 may be configured to have different shapes, which are not specifically limited herein.

[0083] In the implementation mode of the present utility model, Fig. 9 In the illustrated embodiment, a second avoidance groove 420 facing the housing 20 is provided on the heat-insulating support member 400 , and at least a portion of the circumferential limiting portion 520 passes through the second mounting hole 21 and is inserted into the second avoidance groove 420 .

[0084] By setting a second avoidance groove 420 on the insulation support member 400, the front end of the circumferential limiting portion 520 can be inserted into the second avoidance groove 420 to play a role of accommodation and limiting, thereby preventing the circumferential limiting portion 520 from directly abutting against the insulation support member 400 and affecting the installation effect.

[0085] The designer can adjust the specific structure of the second avoidance groove 420 according to the use requirements, and no specific limitation is made here. Preferably, the second avoidance groove 420 and the front end of the circumferential limit portion 520 are substantially configured to have the same shape, thereby helping to reduce or eliminate the installation gap between the second avoidance groove 420 and the front end of the circumferential limit portion 520, thereby improving the accommodation effect.

[0086] In another feasible implementation manner of the present utility model, as Fig.10 and Fig.11 In the embodiment shown, the anti-rotation structure includes an anti-rotation portion 111 protruding from the edge of the first mounting hole 110, and an anti-rotation groove 211 provided at the edge of the second mounting hole 21. In addition, the first mounting hole 110 is configured as a polygon, and the second mounting hole 21 is configured as a polygon. The anti-rotation structure also includes an axial limiting portion 510 and a circumferential limiting portion 520 provided on the gasket 500.

[0087] By respectively setting an anti-rotation portion 111 and an anti-rotation groove 211 between the external bracket 100 and the outer shell 20, and setting the first mounting hole 110 and the second mounting hole 21 to be polygonal, a variety of anti-rotation structures are provided between the external bracket 100 and the outer shell 20, which significantly improves the anti-rotation effect.

[0088] The arrangement of the anti-rotation portion 111 and the anti-rotation groove 211 can be referred to above and will not be described in detail here. Also, the arrangement of the first mounting hole 110, the second mounting hole 21 and the circumferential anti-rotation portion 111 can be referred to above and will not be described in detail here. When the anti-rotation structure includes the anti-rotation portion 111, the anti-rotation groove 211 and the circumferential limit portion 520 at the same time, as shown in FIG. Fig.11 In the illustrated embodiment, the first avoidance groove 410 and the second avoidance groove 420 may be connected.

[0091] The specific structure, working principle and beneficial effects of the electric water heater mounting structure are the same as those described in the first embodiment, and will not be described in detail here. The electric water heater does not need to add additional anti-rotation bolts by using the electric water heater mounting structure, thereby reducing the installation steps, allowing the external bracket 100 to be arranged according to the preset target, and improving the installation efficiency of the electric water heater.

[0092] Specifically, the electric water heater mounting structures are provided in multiple groups, and the multiple groups of electric water heater mounting structures cooperate with each other, thereby improving the installation stability of the electric water heater.
