[0046] The first aspect of the present application discloses a water heater inner tank assembly, Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the water heater tank assembly includes a water heater tank 1000, a water pipe 2000 and a first insulating member 3000. The water heater tank 1000 is made of metal, the water pipe 2000 is made of metal, the water pipe 2000 is arranged in the water heater tank 1000, and the water pipe 2000 is connected to the interior of the water heater tank 1000. The first insulating member 3000 is arranged between the water heater tank 1000 and the water pipe 2000 to insulate the water heater tank 1000 from the water pipe 2000.

[0047] By designing the material of the water pipe 2000 to be metal, the water pipe 2000 is not easily deformed when the water temperature rises, and has better impact resistance, aging resistance and dry-burning resistance than plastic. At the same time, based on the fact that the material of the water pipe 2000 is metal, a first insulating member 3000 is provided. The first insulating member 3000 insulates the water heater tank 1000 from the water pipe 2000, thereby avoiding excessive consumption of the magnesium rod and protecting the water pipe 2000.

[0048] Specifically, the water heater is a vertical water heater, and the water heater inner tank 1000 is a vertical columnar structure as a whole. The water heater inner tank 1000 is a component for storing water. The water heater also includes a heater arranged in the water heater inner tank 1000, and the water in the water heater inner tank 1000 is heated by the heater so that the water becomes hot water, which is then supplied to the user. The material of the water heater inner tank 1000 is generally metal, that is, the water heater inner tank 1000 is mainly made of metal, and the metal can be copper alloy, iron alloy or aluminum alloy, etc. For example, the material of the water heater inner tank 1000 is stainless steel. The water heater inner tank 1000 is connected to a water pipe 2000 to achieve water inlet or water outlet. It can be understood that the water pipe 2000 can be used for water inlet (i.e., constituting a water inlet pipe) or for water outlet (i.e., constituting a water outlet pipe). The following is an example of the water pipe 2000 constituting a water inlet pipe. The water pipe 2000 is disposed in the water heater inner tank 1000 and extends into the interior of the water heater inner tank 1000, thereby communicating with the interior of the water heater inner tank 1000. Water provided by an external water source enters the interior of the water heater inner tank 1000 through the water pipe 2000.

[0049] In the related art, the material of the water pipe 2000 is plastic, that is, the water pipe 2000 is mainly made of plastic, but plastic is easily deformed when heated, especially when the water in the water heater tank 1000 needs to be heated to a higher temperature, the water pipe 2000 is more likely to deform, and the longer the length of the water pipe 2000, the more serious the deformation due to heat. In some cases, when the water heater is dry-burned, it will directly cause damage to the water pipe 2000.

[0050] For this reason, in the present embodiment, the material of the water pipe 2000 is designed to be metal, that is, the water pipe 2000 is mainly made of metal, and the metal may be a copper alloy, an iron alloy or an aluminum alloy. For example, the material of the water pipe 2000 is stainless steel. In this way, the water pipe 2000 is not easily deformed by temperature, and has a certain degree of corrosion resistance and high anti-dry burning performance.

[0051] It is understandable that the water heater generally includes a magnesium rod disposed in the inner tank 1000 of the water heater, and the magnesium rod acts as an anode to be consumed, thereby protecting the inner tank 1000 of the water heater. When the material of the water pipe 2000 is designed to be metal, the magnesium rod will also form a protection for the water pipe 2000, which will cause the magnesium rod to be consumed too quickly. For this reason, in the present embodiment, a first insulating member 3000 is provided, and the first insulating member 3000 is disposed between the inner tank 1000 of the water heater and the water pipe 2000, and is used to insulate the inner tank 1000 of the water heater from the water pipe 2000, so that the magnesium rod-water-water pipe 2000-magnesium rod cannot form a closed loop, that is, the magnesium rod does not need to consume itself to protect the water pipe 2000, and avoids the magnesium rod from being consumed too quickly to protect the water pipe 2000. It is understandable that the first insulating member 3000 is made of an insulating material, such as silicone, rubber, plastic or ceramic.

[0052] Combination Figure 3 As shown, in some embodiments, the water heater tank assembly also includes a first connecting seat 4000, which is connected to the water heater tank 1000 and fixed to the water heater tank 1000, and the first insulating member 3000 is arranged between the first connecting seat 4000 and the water pipe 2000, and the first insulating member 3000 insulates the first connecting seat 4000 from the water pipe 2000.

[0053] Specifically, the wall of the water heater inner tank 1000 is thin-walled, which makes it inconvenient to install the water pipe 2000. For this reason, a first connecting seat 4000 is provided. The first connecting seat 4000 is a tubular structure and is connected to the water heater inner tank 1000. There are many ways to connect the first connecting seat 4000 to the water heater inner tank 1000, such as welding, screwing, clamping, etc., so that the first connecting seat 4000 is fixed to the water heater inner tank 1000 and protrudes relative to the water heater inner tank 1000. By providing the first connecting seat 4000, a basis is provided for the installation of the first insulating member 3000 and the water pipe 2000, thereby better supporting the first insulating member 3000 and the water pipe 2000.

[0054] It is understandable that the first connection seat 4000 is connected to the water heater inner tank 1000, and the first insulating member 3000 insulates the first connection seat 4000 from the water pipe 2000, so that the water heater inner tank 1000 is insulated from the water pipe 2000. It is also through such assembly that the material of the first connection seat 4000 can also be metal, and the metal can be copper alloy, iron alloy or aluminum alloy, for example, the material of the first connection seat 4000 is stainless steel, so that the first connection seat 4000 has a higher structural strength, and the first connection seat 4000 can be fixed to the water heater inner tank 1000 by welding, and the connection stability is high.

[0055] Combination Figure 3 and Figure 7 As shown, in some embodiments, the first insulating member 3000 is inserted into the first connecting seat 4000 , and the water pipe 2000 is inserted into the first insulating member 3000 .

[0056] Specifically, the water heater inner tank 1000 has a mounting hole 1100, which is connected to the interior of the water heater inner tank 1000. The first connecting seat 4000 is a hollow tubular structure. After the first connecting seat 4000 is connected to the water heater inner tank 1000, it is connected to the mounting hole 1100, that is, the first connecting seat 4000 is connected to the interior of the water heater inner tank 1000. The first insulating member 3000 is a hollow ring structure and is inserted into the first connecting seat 4000. The water pipe 2000 is inserted into the first insulating member 3000 and extends from the mounting hole 1100 into the interior of the water heater inner tank 1000. By inserting the first insulating member 3000 into the first connecting seat 4000 and the water pipe 2000 into the water pipe 2000, the contact area is increased and the installation stability of the water pipe 2000 is enhanced.

[0057] For example, combined with Fig.10 and Fig.11 As shown, in some embodiments, the first connecting seat 4000 is provided with a second step surface 4200, and the second step surface 4200 is arranged on the outside of the first connecting seat 4000. When the first connecting seat 4000 is connected to the water heater tank 1000, part of the first connecting seat 4000 is inserted into the mounting hole 1100, and the second step surface 4200 is abutted against the periphery of the mounting hole 1100, thereby forming an installation positioning for the first connecting seat 4000, and then the first connecting seat 4000 and the water heater tank 1000 are further fastened by welding, and the connection is firm.

[0058] Combination Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments, the water heater tank assembly further includes a second connection seat 5000, and the second connection seat 5000 is connected to the first connection seat 4000 to fix the water pipe 2000 and the first insulating member 3000 for easy assembly.

[0059] Specifically, the second connection seat 5000 is connected to the first connection seat 4000, so as to be fixed on the first connection seat 4000, and the second connection seat 5000 is connected to the first connection seat 4000 to realize the fixation of the water pipe 2000 and the first insulating member 3000, that is, the water pipe 2000 and the first insulating member 3000 are fixed between the second connection seat 5000 and the first connection seat 4000, so as to facilitate the assembly of various components. The second connection seat 5000 is a tubular structure, and there are many ways to connect the second connection seat 5000 and the first connection seat 4000, such as welding, screw connection, clamping, etc., so as to be fixed on the first connection seat 4000. It can be understood that the second connection seat 5000 can be used to connect with an external pipeline to receive water supply from the outside.

[0060] There are many ways to connect the second connecting seat 5000 to the first connecting seat 4000 to fix the water pipe 2000 and the first insulating member 3000. For example, the second connecting seat 5000 and the first connecting seat 4000 form a clamp for the water pipe 2000 and the first insulating member 3000 (the clamping can be achieved by direct contact or indirect contact), that is, the second connecting seat 5000 generates a force toward the first connecting seat 4000 on the water pipe 2000 and the first insulating member 3000, and the first connecting seat 4000 generates a force toward the second connecting seat 5000 on the water pipe 2000 and the first insulating member 3000, thereby achieving clamping of the water pipe 2000 and the first insulating member 3000, that is, achieving fixed installation of the water pipe 2000 and the first insulating member 3000, with convenient assembly and high connection firmness.

[0061] Further, on the basis of the second connecting seat 5000 and the first connecting seat 4000 clamping the water pipe 2000 and the first insulating member 3000, the water heater inner tank assembly further includes a second insulating member 6000, combined with Figure 4 and Figure 6As shown, the second insulating member 6000 is disposed between the second connection seat 5000 and the water pipe 2000, so that the second insulating member 6000 insulates the second connection seat 5000 from the water pipe 2000. In this case, the material of the second connection seat 5000 can also be metal, and the metal can be copper alloy, iron alloy or aluminum alloy, such as stainless steel, so that the second connection seat 5000 has a higher structural strength. It can be understood that when the second insulating member 6000 is disposed between the second connection seat 5000 and the water pipe 2000, the second connection seat 5000 and the first insulating member 3000 can be in direct contact, or the second insulating member 6000 is disposed between the second connection seat 5000 and the first insulating member 3000 and the water pipe 2000, for example, the second insulating member 6000 forms a whole. The second insulating member 6000 is made of insulating material, such as silicone, rubber, plastic or ceramic, etc. The second insulating member 6000 is designed to be suitable for elastic deformation (such as silicone, rubber), which is more conducive to sealing.

[0062] Combination Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, in some embodiments of the present application, a flange portion 3100 is provided at one end of the first insulating member 3000 , and a first step surface 4100 is provided on the first connecting seat 4000 , and the second connecting seat 5000 and the first step surface 4100 clamp the flange portion 3100 .

[0063] Specifically, when the first insulating member 3000 is assembled to the first connecting seat 4000, the first insulating member 3000 is inserted into the first connecting seat 4000. It can be understood that the first insulating member 3000 is inserted into the first connecting seat 4000 and installed. By setting the first step surface 4100 on the first connecting seat 4000, when the first insulating member 3000 is installed in place, the flange portion 3100 of the first insulating member 3000 abuts against the first step surface 4100, thereby achieving the installation positioning of the first insulating member 3000, and then the second connecting seat 5000 is connected to the first connecting seat 4000, and the second connecting seat 5000 cooperates with the first step surface 4100 to clamp the flange portion 3100, thereby achieving the fixation of the first insulating member 3000.

[0064] In some embodiments, the first insulating member 3000 and the first connecting seat 4000 are interference fit to prevent water leakage between the first insulating member 3000 and the first connecting seat 4000, thereby better fixing the first insulating member 3000.

[0065] For example, the first insulating member 3000 includes a sleeve portion 3200 and a flange portion 3100, wherein the flange portion 3100 is disposed at one end of the sleeve portion 3200, which is equivalent to the flange portion 3100 being convex relative to the sleeve portion 3200 in the radial direction, the water pipe 2000 is passed through the sleeve portion 3200, the flange portion 3100 is used to abut against the first step surface 4100, and the sleeve portion 3200 is interference-fitted with the first connecting seat 4000 when the first insulating member 3000 is passed through the first connecting seat 4000. In particular, the first insulating member 3000 can be designed to be suitable for elastic deformation, and when the first insulating member 3000 is installed on the first connecting seat 4000, the first insulating member 3000 has a certain degree of deformation, thereby interference-fitting with the first connecting seat 4000, eliminating the gap between the first insulating member 3000 and the first connecting seat 4000 as much as possible to prevent water leakage.

[0066] Combination Figure 7 and Figure 8 As shown, in some embodiments, the sleeve portion 3200 is provided with a plurality of sealing teeth 3210, and a plurality means two or more, that is, the number of the sealing teeth 3210 is at least two, and the plurality of sealing teeth 3210 are alternately arranged along the length direction of the sleeve portion 3200. When the first insulating member 3000 is inserted into the first connecting seat 4000, the sealing teeth 3210 abut against the first connecting seat 4000 to improve the sealing performance.

[0067] Specifically, the sealing teeth 3210 of the first insulating member 3000 are arranged on the circumferential surface, specifically on the circumferential surface of the sleeve portion 3200 of the first insulating member 3000. The sealing teeth 3210 surround the sleeve portion 3200. When the assembly of the first connecting seat 4000, the first insulating member 3000 and the water pipe 2000 is completed, the sleeve portion 3200 is located between the first connecting seat 4000 and the water pipe 2000, so that multiple sealing teeth 3210 abut against the first connecting seat 4000. By staggered arrangement of multiple sealing teeth 3210, the sealing performance between the first insulating member 3000 and the first connecting seat 4000 is improved.

[0068] Combination Figure 4 , Figure 6 and Figure 7As shown, in some embodiments, a flange 2100 is provided at one end of the water pipe 2000, and the flange 2100 is used to abut against the end of the first insulating member 3000. Specifically, the water pipe 2000 is inserted into the first insulating member 3000 and installed in the first insulating member 3000 by insertion. By providing the flange 2100 at one end of the water pipe 2000, when the water pipe 2000 is installed in place, the flange 2100 abuts against the end of the first insulating member 3000, for example, the flange 2100 abuts against the flange 3100 of the first insulating member 3000, thereby forming the installation positioning of the water pipe 2000. For example, the flange 2100 abuts against the end (the flange portion 3100) of the first insulating member 3000 in the direction of gravity, and when the second connecting seat 5000 is connected to the first connecting seat 4000, the second connecting seat 5000 cooperates with the first step surface 4100 to clamp the flange 2100 and the turned-over portion 3100, thereby fixing the water pipe 2000 and the first insulating member 3000.

[0069] In some embodiments, the first insulating member 3000 is interference fit with the water pipe 2000, and the interference fit between the water pipe 2000 and the first insulating member 3000 can better fix the water pipe 2000, and the interference fit between the water pipe 2000 and the first insulating member 3000 can also prevent water from leaking between the water pipe 2000 and the first insulating member 3000. For example, the first insulating member 3000 includes a sleeve portion 3200 and a flange portion 3100, and the flange portion 3100 is arranged at one end of the sleeve portion 3200, which is equivalent to the flange portion 3100 being convex relative to the sleeve portion 3200 in the radial direction, and the water pipe 2000 is inserted into the sleeve portion 3200, and the sleeve portion 3200 and the water pipe 2000 are interference fit.

[0070] Furthermore, the first insulating member 3000 is suitable for elastic deformation, and the diameter of the water pipe 2000 is larger than the inner diameter of the first insulating member 3000. When the water pipe 2000 is passed through the first insulating member 3000, the first insulating member 3000 is deformed to a certain extent, thereby having an interference fit with the water pipe 2000, thereby eliminating the gap between the first insulating member 3000 and the water pipe 2000 as much as possible to prevent water leakage.

[0071] Combination Figures 4 to 6As shown, in some embodiments, the first step surface 4100 is disposed inside the first connecting seat 4000 , and the second connecting seat 5000 is connected to the inside of the first connecting seat 4000 , thereby cooperating to achieve clamping of the flange portion 3100 . Specifically, when the first insulating member 3000 is assembled to the first connecting seat 4000, the first insulating member 3000 is inserted into the first connecting seat 4000, that is, the first insulating member 3000 is installed inside the first connecting seat 4000. It can be understood that the first insulating member 3000 is inserted into the inside of the first connecting seat 4000, and the first step surface 4100 is set inside the first connecting seat 4000. When the first insulating member 3000 is installed in place, the flange portion 3100 of the first insulating member 3000 abuts against the first step surface 4100, thereby realizing the installation and positioning of the first insulating member 3000. After the second connecting seat 5000 is connected to the inside of the first connecting seat 4000, the second connecting seat 5000 cooperates with the first step surface 4100 to clamp the flange portion 3100 and the flange 2100, thereby realizing the fixation of the first insulating member 3000 and the water pipe 2000.

[0072] The second aspect of the present application discloses a water heater, Figures 1 to 11 As shown, the water heater includes a magnesium rod and the above-mentioned water heater inner tank assembly, and the magnesium rod is arranged in the water heater inner tank 1000. The water heater inner tank assembly includes the water heater inner tank 1000, a water pipe 2000 and a first insulating member 3000. The water heater inner tank 1000 is made of metal, the water pipe 2000 is made of metal, the water pipe 2000 is arranged in the water heater inner tank 1000, and the water pipe 2000 is connected to the inside of the water heater inner tank 1000. The first insulating member 3000 is arranged between the water heater inner tank 1000 and the water pipe 2000, and is used to insulate the water heater inner tank 1000 from the water pipe 2000.

[0073] By designing the material of the water pipe 2000 to be metal, the water pipe 2000 is not easily deformed when the water temperature rises, and has better impact resistance, aging resistance and dry-burning resistance than plastic. At the same time, based on the fact that the material of the water pipe 2000 is metal, a first insulating member 3000 is provided. The first insulating member 3000 insulates the water heater tank 1000 from the water pipe 2000, thereby avoiding excessive consumption of the magnesium rod and protecting the water pipe 2000.

[0074] Specifically, the water heater is a vertical water heater, and the water heater inner tank 1000 is a vertical columnar structure as a whole. The water heater inner tank 1000 is a component for storing water. The water heater also includes a heater arranged in the water heater inner tank 1000, and the water in the water heater inner tank 1000 is heated by the heater to make the water hot water, so as to be provided to the user. The material of the water heater inner tank 1000 is generally metal, that is, the water heater inner tank 1000 is mainly made of metal, and the metal can be copper alloy, iron alloy or aluminum alloy, for example, the material of the water heater inner tank 1000 is stainless steel. The water heater inner tank 1000 is connected to a water pipe 2000 to achieve water inlet or water outlet. It can be understood that the water pipe 2000 can serve as water inlet (i.e., constitute a water inlet pipe) or as water outlet (i.e., constitute a water outlet pipe). For example, the water pipe 2000 constitutes a water inlet pipe. The water pipe 2000 is arranged in the water heater inner tank 1000 and extends into the interior of the water heater inner tank 1000, thereby communicating with the interior of the water heater inner tank 1000. Water provided by an external water source enters the interior of the water heater inner tank 1000 from the water pipe 2000.

[0075] In this embodiment, the material of the water pipe 2000 is designed to be metal, that is, the water pipe 2000 is mainly made of metal, and the metal can be a copper alloy, an iron alloy or an aluminum alloy. For example, the material of the water pipe 2000 is stainless steel, so that the water pipe 2000 is not easily deformed by temperature, and has a certain corrosion resistance and high anti-dry burning performance. It can be understood that the magnesium rod is set in the water heater tank 1000, and the magnesium rod acts as an anode to be consumed, thereby protecting the water heater tank 1000. When the material of the water pipe 2000 is designed to be metal, the magnesium rod will also form a protection for the water pipe 2000, which will cause the magnesium rod to be consumed too quickly. To this end, in this embodiment, a first insulating member 3000 is provided, and the first insulating member 3000 is provided between the water heater inner tank 1000 and the water pipe 2000, and is used to insulate the water heater inner tank 1000 from the water pipe 2000, so that the magnesium rod-water-water pipe 2000-magnesium rod cannot form a closed loop, that is, the magnesium rod does not need to consume itself to protect the water pipe 2000, and the magnesium rod is prevented from being consumed too quickly to protect the water pipe 2000. It can be understood that the first insulating member 3000 is made of an insulating material, such as silicone, rubber, plastic or ceramic.
