Description

Technical Field

[0001] The utility model relates to the technical field of electric water heaters, in particular to a hanging rack and an electric water heater. Background Art

[0002] Chinese patent publication CN102374640A discloses an electric water heater, which includes an inner tank, a heat-insulating material, an outer shell, a hanger, and a connector. The inner tank is placed inside the outer shell, and the heat-insulating material is filled in the gap between the inner tank and the outer shell. The main technical feature is that it also includes a lining plate, which is located inside the outer shell and is tightly attached to the inner wall of the outer shell. The lining plate, the outer shell, and the hanger are fastened in sequence by the connector. The patent publication provides a fixed hanger for the water heater, but there is no support between the fixed hanger and the inner tank of the water heater. The fixed hanger is only connected to the outer shell, which easily causes the outer shell to sag when the outer shell is subjected to force.

[0003] In the existing technology, the electric water heater is usually provided with an inner bracket on the inner tank, and the outer bracket and the outer shell are fixed to the inner bracket of the inner tank by bolt connectors. Since the inner bracket is made of iron plate, part of the heat in the inner tank is easily transferred to the outer shell or the outer bracket through the inner bracket, resulting in heat loss, resulting in poor insulation effect and other defects. In order to overcome these defects, part of the heat of the inner tank is prevented from being transferred to the outer shell or the outer bracket through the inner bracket, so as to improve the insulation effect of the electric water heater and ensure the insulation level of the inner tank and the outer shell. It is urgent to improve the bracket of the existing electric water heater. Utility Model Content

[0033] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that the present invention will be comprehensive and complete and fully convey the concepts of the example embodiments to those skilled in the art. The same reference numerals in the figures represent the same or similar structures, and thus their detailed description will be omitted.

[0034] Example

[0035] A first aspect of the utility model provides a bracket for installing an electric water heater, the bracket comprising: an outer bracket 1 and an inner lining bracket 2;

[0036] The external bracket 1 is arranged on the outer wall of the shell 4 of the electric water heater, and the lining bracket 2 is arranged on the inner wall of the shell 4 of the electric water heater corresponding to the external bracket 1. The external bracket 1 and the lining bracket 2 are fixed to the shell 4 of the electric water heater by fasteners;

[0037] A support seat 6 is provided at the lower end of the liner bracket 2 toward the inner tank 5 of the electric water heater. The support seat 6 abuts against the inner tank 5 , and the support seat 6 provides thermal insulation and electrical insulation between the inner tank 5 and the outer shell 4 .

[0038] Example

[0039] As attached Figure 1 As shown, a cross-sectional view of the water heater installation structure of the utility model; a cylindrical water heater is installed on the wall of a building using the bracket of the utility model. The cylindrical water heater comprises an inner tank 5 and an outer shell 4; the bracket comprises: an inner liner bracket 2, an outer bracket 1 and a bolt connector 3. The outer bracket 1 is located outside the outer shell, and the inner liner bracket 2 is located inside the outer shell and is arranged corresponding to the outer bracket 1. Corresponding through holes are arranged on the inner liner bracket 2, the outer shell 4 and the outer bracket 1 for passing the bolt connector 3. The inner liner bracket 2 and the outer bracket 1 have a curvature design adapted to the outer shell 4 to provide maximum support for the water heater shell. The outer surface of the inner liner bracket 2 is tightly attached to the inner wall of the outer shell 4, and the support seat 6, the inner liner bracket 2, the outer shell 4, and the outer bracket 1 are fastened in sequence by the bolt connector 3. A nut 21 is welded on the upper end of the inner liner bracket 2, and the inner liner bracket 2, the outer shell and the outer bracket 1 are fixed into one body by the bolt connector 3. The outer periphery of the nut 21 also has an insulating material sheath for insulation to ensure electrical insulation between the inner liner 5 and the outer shell 4. There is no force-bearing support bracket on the inner liner 5. The nut 21 can also be fixed to the liner bracket 2 in other ways, such as gluing or hot and cold embedding.

[0040] The support seat 6 is arranged at the lower end of the liner bracket 2 and is made of a material with electrical insulation and thermal insulation. Its height is such that one end of the support seat 6 abuts against the outer shell 4 and the other end abuts against the inner tank 5, providing support for the inner tank by the outer shell. In general, a water heater fills a heat-insulating material between the outer shell 4 and the inner tank 5 to provide a heat-insulating function for the hot water in the inner tank. This type of heat-insulating material usually uses a synthetic foaming material. Although it has good heat-insulating performance, it is not strong enough to resist pressure, which easily causes the inner tank 5 to move inside the outer shell 4.

[0041] The utility model specifically designs the inner liner bracket 2 and the outer bracket 1 to be arc-shaped in order to solve this problem, and installs the support seat 6 at the lower end of the inner liner bracket 2 and the outer bracket 1. In this position, the support seat 6 is located at the lower side of the inner tank 5. When the inner liner bracket 2 and the outer bracket 1 are bolted and fixed, the support seat 6 simultaneously abuts against the outer shell 4 and the inner tank 5, providing an upward support force to the inner tank 5. When the water heater is provided with at least one bracket, the inner tank 5 has a good stability and support function, ensuring that it does not move.

[0042] The outer bracket 1 in the bracket of the utility model can be made of metal material, which has good strength and is easy to process. The inner lining bracket 2 can be made in two ways. One is that the inner lining bracket 2 is made of metal material, and the middle part of the inner lining bracket 2 has protruding reinforcing ribs 22 to increase the thickness and provide greater strength. Figure 2 shown.

[0043] As described in the first aspect of the utility model, the lining bracket 2 and the support seat 6 are independent structures, and the lining bracket 2 is made of metal plate; a nut 21 is provided on the upper end of the lining bracket 2; so that the external bracket 1 is connected to the lining bracket 2 through the bolt connector 3;

[0044] A first through hole 23 is provided at the lower end of the lining bracket 2, and the support seat 6 is provided with a second through hole 64 corresponding to the first through hole 23; the second through hole 64 includes an embedded inner hole 62 for installing an embedded nut 61; the side of the support seat 6 close to the lining bracket 2 is provided with a buckle 63 that cooperates with the lining bracket 2.

[0045] As described in the first aspect of the utility model, the support seat 6 includes a flange 65 surrounding the second through hole 64, and the flange 65 extends into the first through hole 23 on the liner bracket 2. The flange 65 provides a tight fit between the support seat 6 and the metal liner bracket 2. That is, the flange 65 extends into the hole on the liner bracket 2 and forms a tight fit installation.

[0046] As in the hanger described in the first aspect of the utility model, the nut 21 is welded to the upper end of the support frame of the lining bracket 2. A reinforcing rib 22 with increased thickness is arranged in the middle of the lining bracket 2.

[0047] As described in the first aspect of the utility model, the support seat 6 is an injection molded part, and the support seat 6 has insulation and heat insulation properties, and provides thermal insulation and electrical insulation between the liner bracket 2 and the inner liner 5, and the support force of the shell 4 on the inner liner 5. The shape and structure of the support seat 6 are shown in the attached Figure 3 shown.

[0048] The second technical solution is that the liner bracket 2 is made entirely of a material that has both thermal isolation and electrical insulation, and can also provide a sufficient force-bearing structure. Figure 4 As shown, the liner bracket 2 is made of non-metallic material.

[0049] As described in the first aspect of the utility model, the lining bracket 2 and the support seat 6 are an integral structure made of injection molding, an upper support 25 is arranged at the upper end of the lining bracket 2, and a support seat 6 is arranged at the lower end of the lining bracket 2, a lower support 24 is arranged inside the support seat 6, and nuts 61 are respectively embedded inside the upper support 25 and the lower support 24; so that the external bracket 1 is connected to the lining bracket 2 through the bolt connector 3.

[0050] When the liner bracket 2 is made of non-metallic materials, it is usually made by injection molding. The liner bracket 2 made by injection molding has an arc shape, and a nut fixing hole is set at the upper end of the liner bracket 2, and a nut 21 is installed in the nut fixing hole. A support seat 6 is directly generated at the lower end of the liner bracket 2, and a hole is also set inside the support seat 6 to install the fixing nut. The advantage of embedded injection molding is that the liner bracket 2 is molded in one time. The productivity is very high.

[0051] The function of the support seat 6 of the utility model is to eliminate the metal connecting parts between the outer shell 4 and the inner tank 5, thereby isolating the external conduction of heat and improving the thermal insulation effect. In addition, when the electric water heater filled with water is installed, without the support seat 6, the bottom of the hanging plate of the electric water heater is subjected to force. Since the foaming material filled between the inner tank and the outer shell is a thermal insulation material and cannot be used as a supporting structure, it will cause the outer shell to be concave toward the side of the inner tank, and a series of other problems will arise over time. After adding the support seat 6 to act as a supporting structure to bear force, there will be no problem of force-induced concavity.

[0052] The second aspect of the utility model provides an electric water heater, the electric water heater comprising: an inner tank 5 and an outer shell 4; characterized in that the electric water heater further comprises a rack: the rack comprises an outer rack 1 and an inner liner bracket 2;

[0053] The external bracket 1 is arranged on the outer wall of the outer shell 4 of the electric water heater, the inner lining bracket 2 is arranged on the inner wall of the outer shell (4) of the electric water heater corresponding to the external bracket 1, and the external bracket 1 and the inner lining bracket 2 are fixed to the outer shell 4 of the electric water heater by fasteners;

[0054] A support seat 6 is provided at the lower end of the liner bracket 2 toward the inner tank of the electric water heater. The support seat 6 abuts against the inner tank 5 , and the support seat 6 provides thermal insulation and electrical insulation between the inner tank 5 and the outer shell 4 .

[0055] For a water heater, there may be more than two brackets to provide sufficient stability and safety margin for the water heater hung on the wall.

[0056] As described in the second aspect of the utility model, the electric water heater further comprises a support seat 6, the support seat 6 is located between the inner tank 5 and the liner bracket 2, and the two ends of the support seat 6 are respectively in close contact with the outer surface of the inner tank 5 and the inner surface of the liner bracket 2.

[0057] As for the electric water heater described in the second aspect of the utility model, the outer surface of the liner bracket 2 of the electric water heater is tightly attached to the inner wall of the outer shell 4, and the support seat 6, the liner bracket 2, the outer shell 4, and the external bracket 1 are fastened and connected in sequence by bolt connectors 3.

[0058] As described in the second aspect of the utility model, the electric water heater has a heat-insulating material filled between the inner tank 5 and the outer shell 4 of the electric water heater.
