[0036] like Figures 1 to 9 As shown, the utility model provides an electric water heater, comprising:
[0037] The outer cylinder 10 and the anti-electricity wall cover 20 arranged thereon, the outer cylinder 10 is provided with a plurality of connecting holes 11, and the connecting holes 11 are provided with a baffle wall 12 extending toward the inner side of the outer cylinder 10; the anti-electricity wall cover 20 is provided with a plurality of connecting parts 21, and the connecting parts 21 pass through the connecting holes 11 and are adapted to at least a partial area of the baffle wall 12.
[0038] The utility model provides a retaining wall 12 extending toward the inner side of the outer cylinder 10 on the connecting hole 11 of the outer cylinder 10. After the outer cylinder 10 is connected with the anti-electrical wall cover 20, the retaining wall 12 blocks the foaming material at the edge of the connecting hole 11, thereby preventing the foaming material from overflowing the connecting hole 11.
[0039] In this embodiment, the connection part 21 is preferably matched with the connection hole 11 and the retaining wall 12. Therefore, the retaining wall 12 and the connection part 21 are structurally fitted, and the retaining wall 12 can play a good role in blocking the foam.
[0040] In this embodiment, preferably, at least four connecting parts 21 are provided on the anti-electricity wall cover 20, which are respectively arranged on the inner wall of the anti-electricity wall cover 20 and protrude from the inner wall of the anti-electricity wall cover 20. Specifically, the connecting parts 21 include upper connecting parts and lower connecting parts respectively arranged on the upper inner wall and the lower inner wall of the anti-electricity wall cover 20, and at least two upper connecting parts are provided, and at least two lower connecting parts are provided, which are respectively arranged at the four corners of the anti-electricity wall cover 20. The four corners ensure the fixing effect between the anti-electricity wall cover 20 and the outer cylinder 10.
[0041] Furthermore, a crossbeam 23 is provided on the upper connection part, one side of the crossbeam 23 is arranged on the upper inner wall of the anti-electrical wall cover 20, and the other side extends outward to form an angle with the upper inner wall of the anti-electrical wall cover 20. The upper connection part is arranged on the crossbeam 23 at intervals, extends in the same direction as the crossbeam 23 and protrudes from the upper inner wall. The crossbeam 23 is provided to reinforce the connection part between the upper connection part and the anti-electrical wall cover 20, and a plurality of upper connection parts are connected with the crossbeam 23 to form an integrated structure, which is convenient for positioning the upper connection part and facilitating the installation of the outer cylinder 10 and the anti-electrical wall cover 20.
[0042] In this embodiment, each lower connection part is preferably independently provided. Since there are other structures below the anti-electrical wall cover 20, the lower connection part is independently provided to save space.
[0043] In this embodiment, the length of the connection part 21 is preferably greater than the sum of the depth of the connection hole 11 and the height of the retaining wall 12. Therefore, after connection, the end of the connection part 21 can extend out of the retaining wall 12. Specifically, a protrusion 22 is provided on the connection part 21, and when the outer cylinder 10 and the anti-electrical wall cover 20 are in the connected state, the protrusion 22 extends out of the retaining wall 12. It plays a fixing role, ensures that the connection structure of the outer cylinder 10 and the anti-electrical wall cover 20 is stable, and prevents the anti-electrical wall cover 20 from slipping.
[0044] In this embodiment, the protrusion 22 can be engaged with the edge of the baffle 12. Therefore, shaking between the outer cylinder 10 and the anti-electrical wall cover 20 is avoided. Specifically, the connecting portion 21 has an upper connecting portion and a lower connecting portion, the protrusion 22 of the upper connecting portion is arranged on the upper surface, and the protrusion 22 of the lower connecting portion is arranged on the lower surface, so the protrusions 22 on the upper and lower sides respectively engage with the baffle 12 on the upper and lower sides to play a fixing role. Therefore, the connection structure between the outer cylinder 10 and the anti-electrical wall cover 20 is stable. Of course, the connecting portion 21 can also be arranged in multiple rows, which is not limited here.
[0045] In this embodiment, the protrusion 22 is preferably elastic. Therefore, the protrusion 22 can pass through the connection hole 11 and the retaining wall 12 without restriction, and can be protruded and fixed at the edge of the retaining wall 12. The protrusion 22 can be made of an elastic material, or an elastic component can be added to the connection part 21 to connect with the protrusion 22, so that the protrusion 22 has elasticity, which is not limited here.
[0046] In a preferred embodiment, the protrusion 22 is made of elastic plastic. Furthermore, the protrusion 22 and the connecting portion 21 are an integral structure and are integrally formed during processing, which facilitates processing.
[0047] In another preferred embodiment, a through hole is provided on the connecting portion 21, and the protrusion 22 is connected to the elastic component so that the protrusion 22 extends out of the through hole in a natural state. When the protrusion 22 is subjected to force, the elastic component produces elastic deformation, driving the protrusion 22 to retract into the through hole.
[0048] In this embodiment, one end of the retaining wall 12 is connected to the connecting hole 11 located inside the outer tube 10, and the retaining wall 12 located at this end has the same shape as the connecting hole 11. Therefore, the retaining wall 12 is equivalent to isolating the edge of the connecting hole 11, and when the foaming material filled in the outer tube 10 foams and expands, the retaining wall 12 can prevent the foaming material from entering the connecting hole 11.
[0049] In this embodiment, at least part of the connecting portion 21 is a columnar structure. Specifically, the area near one end of the anti-electrical wall cover 20 is a columnar structure, which is convenient for installation with the connecting hole 11. The columnar structure can be a prismatic structure or a cylindrical structure, which is not limited here.
[0050] In this embodiment, the cross-sectional area of the end of the connecting portion 21 at the end away from the anti-electrical wall cover 20 is smaller than the cross-sectional area of the columnar structure. Specifically, the structure of the end is a prism, a pyramid, a truncated cone or a cone. Therefore, the cross-sectional area of the end of the connecting portion 21 at the end away from the anti-electrical wall cover 20 is gradually reduced, so when the outer cylinder 10 and the anti-electrical wall cover 20 are installed, it is convenient for the connecting portion 21 to extend into the connecting hole 11.
[0051] In this embodiment, the retaining wall 12 is preferably disposed perpendicularly to the connecting hole 11 , so as to ensure that the passage formed by the retaining wall 12 is more unobstructed, and facilitate the connection between the connecting portion 21 and the connecting hole 11 .
[0052] The retaining wall 12 may be integrally formed with the outer cylinder 10, or may be welded and fixed to the outer cylinder 10. Preferably, the outer cylinder 10 is punched at the connecting hole 11, and the punched flange is the retaining wall 12, so there is no need to add additional steps, thereby improving production efficiency.
[0053] In this embodiment, the height of the retaining wall 12 is 1 mm to 10 mm, preferably 3 mm.
[0054] The utility model arranges a retaining wall extending toward the inner side of the outer cylinder on the connecting hole of the outer cylinder. After the outer cylinder is connected with the anti-electrical wall cover, the retaining wall blocks the foaming material at the edge of the connecting hole, thereby preventing the foaming material from overflowing the connecting hole.
[0055] The above is only a preferred embodiment of the present invention, and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention. The implementation schemes in the above embodiments can also be further combined or replaced. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the present invention.
