[0003] The existing water heater includes two end caps, two foam pads, an inner tank, and a water pipe. The two foam pads are connected to the two end caps respectively. The inner tank is located between the two foam pads. The foam pads make the inner tank located in the center of the two end caps. The water pipe is connected to the inner tank. The position of the inner tank can be restricted through the water pipe.

[0004] However, since the inner tank is only restricted in position by the water pipe, when the foaming agent is filled into the water heater, the pressure exerted by the foaming agent on the inner tank is relatively large, which can easily cause the inner tank to shift, thus reducing the overall energy efficiency of the machine. Utility Model Content

[0005] In order to solve the above-mentioned problems in the prior art, namely, to solve the problem that the inner tank is only restricted in position by the water pipe, and the inner tank is easily displaced when the foaming agent is filled into the water heater due to the large pressure of the foaming agent, which leads to a decrease in the overall energy efficiency performance, this application provides a fixing structure for the inner tank of a water heater and a water heater.

[0011] In the preferred technical solution of the above-mentioned fixing structure of the inner tank of the water heater, the surface of the fixing plate that abuts against the tank body is an arc surface that matches the outer peripheral wall of the tank body.

[0012] In the preferred embodiment of the above-mentioned fixing structure of the inner tank of the water heater, the side of the fixing plate facing the end cap has a supporting block, and the supporting block abuts against the end cap.

[0013] In the preferred technical solution of the above-mentioned fixing structure of the inner tank of the water heater, the surface of the support block that abuts against the end cap is an arc surface that matches the outer peripheral wall of the end cap.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

It should be understood that such data can be interchanged where appropriate so that embodiments of the utility model described herein can be implemented, for example, in sequences other than those illustrated or described herein.

[0037] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0038] As mentioned in the background section above, with economic development, water heaters have become an essential appliance for many families.

[0039] The existing water heater includes two end caps, two foam pads, an inner tank, and a water pipe. The two foam pads are connected to the two end caps respectively. The inner tank is located between the two foam pads. The foam pads make the inner tank located in the center of the two end caps. The water pipe is connected to the inner tank. The position of the inner tank can be restricted through the water pipe.

[0040] However, since the inner tank is only restricted in position by the water pipe, when the foaming agent is filled into the water heater, the pressure exerted by the foaming agent on the inner tank is relatively large, which can easily cause the inner tank to shift, thus reducing the overall energy efficiency of the machine.

[0041] Therefore, in order to improve or solve the above-mentioned technical problems, this application provides a fixing structure for a water heater inner tank and a water heater. The fixing structure for the water heater inner tank is provided by setting two connecting parts and fixing parts respectively connected to the two connecting parts. The water heater includes an end cap module and an inner tank located in the middle of the end cap module. The fixing structure for the water heater inner tank is set between the end cap module and the inner tank. The connecting parts are connected to the end cap in the end cap module. The fixing parts have a receiving cavity for receiving the end cap of the inner tank and at least part of the tank body. Moreover, the inner wall of the receiving cavity abuts against the outer peripheral wall of at least part of the tank body to restrict and fix the tank body, thereby fixing the inner tank and minimizing the displacement of the inner tank when filling the water heater with foaming agent, thus ensuring the energy efficiency performance of the entire water heater.

[0042] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; identical or similar content will not be repeated in different embodiments.

[0043] Please refer to Figure 1 and Figure 2 This application provides a fixing structure for a water heater inner tank 400, which is used to be disposed between the end cap module and the inner tank 400. The end cap module includes two end caps 300, and the inner tank 400 includes a tank body 410 and two end caps 420 located at both ends of the tank body 410. The fixing structure includes two connectors 100 and fixing members 200 connected to the two connectors 100 respectively.

[0044] The two connectors 100 are respectively connected to the two end caps 300 on the side facing the end cap 420.

[0045] The fastener 200 has a receiving cavity 210 configured to receive the end cap 420 and at least a portion of the bladder 410. The inner wall of the receiving cavity 210 abuts against the outer peripheral wall of at least a portion of the bladder 410 to restrict and fix the bladder 410.

[0046] The water heater also includes an outer shell, which is cylindrical and has its axis arranged horizontally. Two end caps 300 in the end cap module are located at opposite ends of the outer shell. The inner tank 400 is located inside the outer shell, and the opposite ends of the inner tank 400 are respectively connected to the two end caps 300 through a fixing structure. After the inner tank 400 is installed inside the outer shell, there is a certain gap between the inner tank 400 and the outer shell. In order to ensure the connection strength between the inner tank 400 and the outer shell and to ensure the heat preservation effect of the inner tank 400, a foaming agent needs to be filled between the outer shell and the inner tank 400.

[0047] For example, the fastener 200 can be a fastening sleeve with the same inner diameter as the outer diameter of the inner liner 410. After the inner liner 400 is embedded into the fastening sleeve, the end cap 420 facing away from the inner liner 410 abuts against the connector 100, and at least part of the inner liner 410 abuts against the inner wall of the fastening sleeve, thereby fixing the inner liner 400.

[0048] By adopting the above technical solution, by setting two connectors 100 and fixing members 200 respectively connected to the two connectors 100, the connectors 100 are connected to the end caps 300 in the end cap module, and the fixing members 200 have a receiving cavity 210. The receiving cavity 210 is used to receive the end cap 420 of the inner tank 400 and at least part of the tank body 410. Moreover, the inner wall of the receiving cavity 210 abuts against the outer peripheral wall of at least part of the tank body 410 to restrict and fix the tank body 410, thereby fixing the inner tank 400 and minimizing the displacement of the inner tank 400 when filling the water heater with foaming agent, thus ensuring the energy efficiency performance of the entire water heater.

[0049] In some embodiments provided in this application, for example, the fixing member 200 includes at least three fixing plates 220, one end of each fixing plate 220 is connected to the connecting member 100, and each fixing plate 220 is sequentially arranged around the periphery of the connecting member 100 to form a receiving cavity 210. The other end of each fixing plate 220 extends to the outside of the gallbladder 410 so that the fixing plate 220 abuts against the outer peripheral wall of the gallbladder 410.

[0050] For example, three fixing plates 220 are provided, and the three fixing plates 220 are connected in sequence to form a fixing sleeve.

[0051] For example, one side of the fixing plate 220 is in line contact with the outer peripheral wall of the bladder body 410.

[0052] By adopting the above technical solution, by setting at least three fixing plates 220, the three fixing plates 220 are sequentially arranged around the periphery of the connector 100 to form a receiving cavity 210. After the inner liner 400 is placed into the receiving cavity 210, the fixing plates 220 abut against the outer peripheral wall of the liner 410, thereby fixing the liner 410.

[0053] In some embodiments provided in this application, there is an exemplary gap between adjacent fixing plates 220.

[0054] For example, three fixing plates 220 are provided, and the spacing between two adjacent fixing plates 220 is the same.

[0055] By adopting the above technical solution, and by making a gap between adjacent fixing plates 220, the material required to form the fixing member 200 is reduced while the fixing member 200 forms the receiving cavity 210, thereby reducing the manufacturing cost of the fixing member 200.

[0056] In some embodiments provided in this application, for example, the surface of the fixing plate 220 that abuts against the bladder body 410 is an arc surface that matches the outer peripheral wall of the bladder body 410.

[0057] For example, the fixing plate 220 is an arc-shaped plate, and the curvature of the arc-shaped plate is consistent with the curvature of the outer peripheral wall of the bladder 410, so that the fixing plate 220 is in surface contact with the outer peripheral wall of the bladder 410.

[0058] By adopting the above technical solution, by setting the end face of the fixing plate 220 that abuts against the inner liner 410 as an arc surface, the fixing plate 220 and the inner liner 410 are in surface contact, thereby ensuring the stability of the fixing member 200 in restricting and fixing the inner liner 400.

[0059] In some embodiments provided in this application, for example, the side of the fixing plate 220 facing the end cap 420 has a support block 230 that abuts against the end cap 420.

[0060] For example, the support block 230 contacts the outer peripheral wall line of the end cap 420.

[0061] By adopting the above technical solution, and by setting the support block 230 so that the support block 230 abuts against the end cap 420, the fixing member 200 can play a limiting and positioning role for the end cap 420, thereby improving the stability of the fixing member 200 in fixing the bladder body 410.

[0062] In some embodiments provided in this application, for example, the surface of the support block 230 that abuts against the end cap 420 is an arc surface that matches the outer peripheral wall of the end cap 420.

[0063] By adopting the above technical solution, by setting an arc surface on the support block 230, the support block 230 and the end cap 420 are in surface contact, which improves the stability of the contact between the support block 230 and the end cap 420, thereby ensuring the stability of the fastener 200 in restricting and fixing the inner liner 400.

[0064] In some embodiments provided in this application, for example, the fixing plate 220 and the connector 100 are integrally formed.

[0065] By adopting the above technical solution, the manufacturing cost of the fixed structure of the water heater inner tank 400 has been reduced.

[0066] In some embodiments provided in this application, the connector 100 is, by way of example, a foam pad.

[0067] By adopting the above technical solution, the manufacturing cost of connector 100 has been reduced.

[0068] In some embodiments provided in this application, exemplary references are made to... Figure 3 The centerline of the receiving cavity coincides with the centerline of the inner liner. The centerline of the receiving cavity is offset by 2-3mm relative to the centerline of the end cap module. The offset direction of the centerline of the receiving cavity is towards the water outlet pipe 500 in the inner liner 400.

[0069] For example, the centerline of the receiving cavity 210 is offset by 2.5 mm relative to the centerline of the end cap module toward the water pipe 500 in the inner liner 400.

[0070] By adopting the above technical solution, when the foaming agent is filled into the water heater, the foaming agent will exert a relatively large pressure on the inner tank 400, causing the inner tank 400 to shift away from the water outlet pipe 500. In order to ensure that the inner tank 400 is in a centered position relative to the water heater after the foaming agent is filled, the offset of the inner tank 400 is planned in advance, so that the center line of the receiving cavity 210 is offset by 2-3mm relative to the center line of the end cover module towards the water outlet pipe 500, thus ensuring the energy efficiency performance of the water heater.

[0071] This application embodiment also provides a water heater, including an end cap module, an inner tank 400, and a fixing structure for the inner tank 400 of any of the above embodiments, wherein the fixing structure for the inner tank 400 is disposed between the end cap module and the inner tank 400.

[0072] The end cap module includes two end caps 300, and the inner liner 400 is disposed between the two end caps 300.

[0073] The structure and principle of the fixing structure of the water heater inner tank 400 have been clearly explained in the above embodiments, and will not be described in detail here.

[0074] By adopting the above technical solution, the fixing structure of the inner tank 400 of the water heater is provided by setting two connectors 100 and fixing members 200 respectively connected to the two connectors 100. The water heater includes an end cap module and an inner tank 400 located in the middle of the end cap module. The fixing structure of the inner tank 400 is set between the end cap module and the inner tank 400. The connectors 100 are connected to the end caps 300 in the end cap module. The fixing member 200 has a receiving cavity 210, which is used to receive the end cap 420 of the inner tank 400 and at least part of the tank body 410. Moreover, the inner wall of the receiving cavity 210 abuts against the outer peripheral wall of at least part of the tank body 410 to restrict and fix the tank body 410, thereby fixing the inner tank 400 and minimizing the displacement of the inner tank 400 when filling the water heater with foaming agent, thus ensuring the energy efficiency performance of the entire water heater.
