[0021] Technical solutions according to embodiments of the present disclosure will be described clearly and completely below in combination with accompanying drawings of the embodiments of the present disclosure. Obviously, the embodiments described below are only part of the embodiments of the present disclosure, rather than all embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present disclosure.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, rear, etc.) in the embodiments of the present disclosure are only used to explain relative positions between various components, movements of various components, or the like under a predetermined posture (as illustrated in the figures). When the predetermined posture changes, the directional indications also change accordingly.

[0023] In the present disclosure, unless otherwise clearly specified and limited, terms, such as “connect”, “fix” or the like, should be understood in a broad sense. For example, it may be fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate; or internal communication of two components or interaction relationship between two components, unless otherwise clearly limited.

[0024] In addition, descriptions, such as “first”, “second” and the like, in the present disclosure are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features associated with “first” and “second” may explicitly or implicitly include at least one of the features. In addition, the technical solutions according to various embodiments of the present disclosure can be combined, but these combinations must be based on the fact that they can be realized by those skilled in the art. When a combination of the technical solutions is contradictory or unattainable, the combination of the technical solutions neither exists nor falls within the scope of the present disclosure.

[0025] In a first aspect according to the present disclosure, a tank assembly for a water heater is provided. As illustrated in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the tank assembly for the water heater includes a water heater tank 1000 made of metal, a water delivery tube 2000, and a first insulation component 3000. The water delivery tube 2000 is disposed in the water heater tank 1000 and made of metal, and is in communication with an interior of the water heater tank 1000. The first insulation component 3000 is disposed between the water delivery tube 2000 and the water heater tank 1000 to insulate the water heater tank 1000 from the water delivery tube 2000.

[0026] The water delivery tube 2000 is designed to be made of metal, such that the water delivery tube 2000 is unlikely to be deformed when a water temperature rises, and has better performance of impact resistance, aging resistance, and dry burning resistance compared with plastic. Furthermore, on the basis that the water delivery tube 2000 is made of metal, the first insulation member 3000 is disposed to insulate the water heater tank 1000 from the water delivery tube 2000, thereby avoiding excessive consumption of a magnesium rod and protecting the water delivery tube 2000.

[0027] In an exemplary embodiment of the present disclosure, the water heater is a vertical water heater. The water heater tank 1000 has a vertical columnar structure as a whole. The water heater tank 1000 is a component for storing water. The water heater further includes a heater disposed in the water heater tank 1000. Water in the water heater tank 1000 is heated by the heater, and thus the water becomes hot water to be supplied to a user for use. The material of the water heater tank 1000 is generally metal. That is, the water heater tank 1000 is mainly made of metal, which may be copper alloy, iron alloy, aluminum alloy, or the like. For example, the water heater tank 1000 is made of stainless steel. The water heater tank 1000 is connected to the water delivery tube 2000 to realize inflow or outflow of water. It should be understood that the water delivery tube 2000 may serve as a water inlet (i.e., a water inlet tube) or a water outlet (i.e., a water outlet tube). As an example, the water delivery tube 2000 is a water inlet tube below. The water delivery tube 2000 is disposed in the water heater tank 1000, and extends into the interior of the water heater tank 1000 to be in communication with the interior of the water heater tank 1000. Water from an external water source enters the interior of the water heater tank 1000 through the water delivery tube 2000.

[0028] In the related art, the material of the water delivery tube 2000 is plastic. That is, the water delivery tube 2000 is mainly made of plastic. However, the plastic is prone to deformation when heated. Especially when the water in the water heater tank 1000 needs to be heated to a higher temperature, the water delivery tube 2000 is more prone to deformation. With an increase in a length of the water delivery tube 2000, the deformation of the water delivery tube 2000 when heated becomes more serious. Even in some cases, when the water heater is dry-burned, the water delivery tube 2000 may be directly damaged.

[0029] Therefore, in this embodiment, the material of the water delivery tube 2000 is designed to be metal. That is, the water delivery tube 2000 is mainly made of metal. The metal may be copper alloy, iron alloy, or aluminum alloy. For example, the water delivery tube 2000 is made of stainless steel, such that the water delivery tube 2000 is unlikely to be deformed due to temperature and has certain corrosion resistance and high dry burning resistance.

[0030] It should be understood that the water heater generally includes a magnesium rod disposed in the water heater tank 1000. The magnesium rod acts as an anode to be consumed to protect the water heater tank 1000. When the water delivery tube 2000 is designed to be made of metal, the magnesium rod can also form protection for the water delivery tube 2000, which may lead to excessive consumption of the magnesium rod. To this end, in this embodiment, the first insulation component 3000 is disposed between the water heater tank 1000 and the water delivery tube 2000 for insulating the water heater tank 1000 from the water delivery tube 2000. In this way, the magnesium rod, water, the water delivery tube 2000, and the magnesium rod cannot form a closed circuit. That is, the magnesium rod does not need to consume itself to protect the water delivery tube 2000, and thus the magnesium rod is prevented from being consumed too quickly to protect the water delivery tube 2000. It should be understood that the first insulation component 3000 is made of an insulating material, such as silicone, rubber, plastic, or ceramic.

[0031] As illustrated in FIG. 3, in some embodiments, the tank assembly for the water heater further includes a first connection base 4000 connected to the water heater tank 1000 to be fixed in the water heater tank 1000. The first insulation component 3000 is disposed between the first connection base 4000 and the water delivery tube 2000 to insulate the first connection base 4000 from the water delivery tube 2000.

[0032] In an exemplary embodiment of the present disclosure, the water heater tank 1000 has a thin wall, which does not facilitate the mounting of the water delivery tube 2000. Therefore, the first connection base 4000 is disposed. The first connection base 4000 has a tubular structure, and is connected to the water heater tank 1000. The first connection base 4000 is connected to the water heater tank 1000 in various ways, such as welding, screwing, engagement, or the like, to allow the first connection base 4000 to be fixed at the water heater tank 1000 and to protrude with respect to the water heater tank 1000. The first connection base 4000 provides the foundation for mounting the first insulation component 3000 and the water delivery tube 2000, which can better achieve support for the first insulation component 3000 and the water delivery tube 2000.

[0033] It should be understood that the first connection base 4000 is connected to the water heater tank 1000. The first insulation component 3000 insulates the first connection base 4000 from the water delivery tube 2000, such that the water heater tank 1000 is insulated from the water delivery tube 2000. It is precisely through this assembly that the first connection base 4000 may also be made of metal, such as copper alloy, iron alloy, or aluminum alloy. For example, the first connection base 4000 is made of stainless steel to allow the first connection base 4000 to have a high structural strength. In addition, the first connection base 4000 can be fixed to the water heater tank 1000 through welding, resulting in high connection stability.

[0034] As illustrated in FIG. 3 and FIG. 7, in some embodiments, the first insulation component 3000 extends through the first connection base 4000. The water delivery tube 2000 extends through the first insulation component 3000.

[0035] In an exemplary embodiment of the present disclosure, the water heater tank 1000 has a mounting hole 1100 in communication with the interior of the water heater tank 1000. The first connection base 4000 has a hollow tubular structure. The first connection base 4000 is connected to the water heater tank 1000 and in communication with the mounting hole 1100. That is, the first connection base 4000 is in communication with the interior of the water heater tank 1000. The first insulation component 3000 has a hollow annular structure and extends through the first connection base 4000. The water delivery tube 2000 extends through the first insulation component 3000, and extends from the mounting hole 1100 into the interior of the water heater tank 1000. Since the first insulation component 3000 extends through the first connection base 4000 and the water delivery tube 2000 extends through the first insulation component 3000, a contact area is increased and mounting stability of the water delivery tube 2000 is enhanced.

[0036] For example, as illustrated in FIG. 10 and FIG. 11, in some embodiments, the first connection base 4000 has a second step surface 4200. The second step surface 4200 is disposed outside the first connection base 4000. When the first connection base 4000 is connected to the water heater tank 1000, the first connection base 4000 is partially inserted into the mounting hole 1100 and the second step surface 4200 is abutted with a periphery of the mounting hole 1100, such that mounting and positioning of the first connection base 4000 is provided. Further, the first connection base 4000 and the water heater tank 1000 are further fastened by welding, resulting in high connection firmness.

[0037] As illustrated in FIG. 3, FIG. 4, FIG. 5, and FIG. 6, in some embodiments, the tank assembly for the water heater further includes a second connection base 5000 connected to the first connection base 4000 to fix the first insulation component 3000 and the water delivery tube 2000, thereby facilitating assembly.

[0038] In an exemplary embodiment of the present disclosure, the second connection base 5000 is connected to the first connection base 4000 to be fixed at the first connection base 4000. In addition, the second connection base 5000 is connected to the first connection base 4000 to achieve fixation of the water delivery tube 2000 and the first insulation component 3000. That is, the water delivery tube 2000 and the first insulation component 3000 are fixed between the second connection base 5000 and the first connection base 4000, which facilitates the assembly of various components. The second connection base 5000 has a tubular structure. The second connection base 5000 and the first connection base 4000 are connected to each other in a variety of ways, such as welding, screwing, engagement, or the like, to be fixed to the first connection base 4000. It should be understood that the second connection base 5000 may be configured to be connected to an external pipeline to receive water supplied from the outside.

[0039] The second connection base 5000 is connected to the first connection base 4000 in various ways to fix the water delivery tube 2000 and the first insulation component 3000. For example, the water delivery tube 2000 and the first insulation component 3000 are sandwiched between the second connection base 5000 and the first connection base 4000, which may be realized by direct contact or indirect contact. That is, the second connection base 5000 exerts a force towards the first connection base 4000 on the water delivery tube 2000 and the first insulation component 3000. The first connection base 4000 exerts a force towards the second connection base 5000 on the water delivery tube 2000 and the first insulation component 3000, to realize clamping on the water delivery tube 2000 and the first insulation component 3000. That is, fixation and mounting of the water delivery tube 2000 and the first insulation component 3000 is realized, which facilitates assembly and has high connection firmness.

[0040] Further, on the basis that the water delivery tube 2000 and the first insulation component 3000 are sandwiched between the second connection base 5000 and the first connection base 4000, the tank assembly for the water heater further includes a second insulation component 6000. As illustrated in FIG. 4 and FIG. 6, the second insulation component 6000 is disposed between the second connection base 5000 and the water delivery tube 2000 to allow the second connection base 5000 to be insulated from the water delivery tube 2000. In this case, the second connection base 5000 may also be made of metal, such as copper alloy, iron alloy, or aluminum alloy, for example, stainless steel, such that the second connection base 5000 has a higher structural strength. It should be understood that when the second insulation component 6000 is disposed between the second connection base 5000 and the water delivery tube 2000, the second connection base 5000 and the first insulation component 3000 may be in direct contact with each other, or the second insulation component 6000 is disposed between the water delivery tube 2000 and the second connection base 5000 and between the first insulation component 3000 and the second connection base 5000. For example, the second insulation component 6000 is formed integrally. The second insulation component 6000 is made of an insulating material, such as silicone, rubber, plastic, ceramic, or the like. The second insulation component 6000 is formed to be elastically deformable, such as silicone or rubber, which is more conducive to sealing.

[0041] As illustrated in FIG. 4, FIG. 7, FIG. 8, and FIG. 9, in some embodiments of the present disclosure, the first insulation component 3000 is provided with a flange portion 3100 at an end of the first insulation component 3000. The first connection base 4000 has a first step surface 4100. The flange portion 3100 is sandwiched between the first step surface 4100 and the second connection base 5000.

[0042] In an exemplary embodiment of the present disclosure, when the first insulation component 3000 is assembled to the first connection base 4000, the first insulation component 3000 extends through the first connection base 4000. It should be understood that the first insulation component 3000 is mounted at the first connection base 4000 through insertion. The first step surface 4100 is disposed at the first connection base 4000, such that the flange portion 3100 of the first insulation component 3000 is abutted with the first step surface 4100 when the first insulation component 3000 is mounted in place, to realize mounting and positioning of the first insulation component 3000. The second connection base 5000 is then connected to the first connection base 4000. The flange portion 3100 is sandwiched between the second connection base 5000 and the first step surface 4100 to fix the first insulation component 3000.

[0043] In some embodiments, the first insulation component 3000 is in an interference fit with the first connection base 4000 to prevent water leakage between the first insulation component 3000 and the first connection base 4000 to better realize fixation of the first insulation component 3000.

[0044] For example, the first insulation component 3000 includes a sleeve portion 3200 and the flange portion 3100. The flange portion 3100 is disposed at an end of the sleeve portion 3200, that is, the flange portion 3100 protrudes relative to the sleeve portion 3200 in a radial direction of the flange portion 3100. The water delivery tube 2000 extends through the sleeve portion 3200. The flange portion 3100 is configured to be abutted with the first step surface 4100. The sleeve portion 3200 is in an interference fit with the first connection base 4000 when the first insulation component 3000 extends through the first connection base 4000. In particular, the first insulation component 3000 may be formed to be elastically deformable. When the first insulation component 3000 is mounted to the first connection base 4000, the first insulation component 3000 has a certain degree of deformation to be in an interference fit with the first connection base 4000 to eliminate a gap between the first insulation component 3000 and the first connection base 4000 as much as possible, preventing water leakage.

[0045] As illustrated in FIG. 7 and FIG. 8, in some embodiments, the sleeve portion 3200 has a plurality of sealing teeth 3210. The plurality of sealing teeth means two or more sealing teeth. That is, at least two sealing teeth 3210 are provided. The plurality of sealing teeth 3210 are arranged at intervals in a length direction of the sleeve portion 3200. When the first insulation component 3000 extends through the first connection base 4000, the plurality of sealing teeth 3210 is abutted with the first connection base 4000 to improve sealing performance.

[0046] In an exemplary embodiment of the present disclosure, the sealing teeth 3210 of the first insulation component 3000 are disposed at a peripheral surface, in particular at a peripheral surface of the sleeve portion 3200 of the first insulation component 3000. The sleeve portion 3200 is surrounded by the sealing teeth 3210. When the assembly of the first connection base 4000, the first insulation component 3000, and the water delivery tube 2000 is completed, the sleeve portion 3200 is located between the first connection base 4000 and the water delivery tube 2000, such that the plurality of sealing teeth 3210 is abutted with the first connection base 4000. With the plurality of sealing teeth 3210 arranged at intervals, the sealing performance between the first insulation component 3000 and the first connection base 4000 is improved.

[0047] As illustrated in FIG. 4, FIG. 6, and FIG. 7, in some embodiments, the water delivery tube 2000 is provided with a flange 2100 at an end of the water delivery tube 2000. The flange 2100 is configured to be abutted with an end portion of the first insulation component 3000. In an exemplary embodiment of the present disclosure, the water delivery tube 2000 is mounted to the first insulation component 3000 through insertion so that the water delivery tube 2000 extends through the first insulation component 3000. With the flange 2100 disposed at the end of the water delivery tube 2000, the flange 2100 is abutted with the end portion of the first insulation component 3000 when the water delivery tube 2000 is mounted in place. For example, the flange 2100 is abutted with the flange portion 3100 of the first insulation component 3000, forming mounting and positioning of the water delivery tube 2000. For example, the flange 2100 is abutted with the end portion (i.e., the flange portion 3100) of the first insulation component 3000 in a gravity direction. When the second connection base 5000 is connected to the first connection base 4000, the second connection base 5000 cooperates with the first step surface 4100 to sandwich the flange 2100 and the flange portion 3100, realizing fixation of the water delivery tube 2000 and the first insulation component 3000.

[0048] In some embodiments, the first insulation component 3000 is in an interference fit with the water delivery tube 2000, which can better realize fixation of the water delivery tube 2000 and prevent water leakage between the water delivery tube 2000 and the first insulation component 3000. For example, the first insulation component 3000 includes a sleeve portion 3200 and the flange portion 3100. The flange portion 3100 is disposed at an end of the sleeve portion 3200, that is, the flange portion 3100 protrudes relative to the sleeve portion 3200 in the radial direction of the flange portion 3100. The water delivery tube 2000 extends through the sleeve portion 3200. The sleeve portion 3200 is in an interference fit with the water delivery tube 2000.

[0049] Further, the first insulation component 3000 is elastically deformable. The water delivery tube 2000 has a diameter greater than an inner diameter of the first insulation component 3000. When the water delivery tube 2000 extends through the first insulation component 3000, the first insulation component 3000 has a certain degree of deformation to be in an interference fit with the water delivery tube 2000 to eliminate the gap between the first insulation component 3000 and the water delivery tube 2000 as much as possible, preventing water leakage.

[0050] As illustrated in FIG. 4 to FIG. 6, in some embodiments, the first step surface 4100 is disposed inside the first connection base 4000. The second connection base 5000 is connected to an interior of the first connection base 4000 to cooperate with each other, to achieve clamping for the flange portion 3100. In an exemplary embodiment of the present disclosure, when the first insulation component 3000 is assembled to the first connection base 4000, the first insulation component 3000 extends through the first connection base 4000. That is, the first insulation component 3000 is mounted to the interior of the first connection base 4000. It should be understood that the first insulation component 3000 is mounted to the interior of the first connection base 4000 through insertion. The first step surface 4100 is disposed at the interior of the first connection base 4000, the flange portion 3100 of the first insulation component 3000 is abutted with the first step surface 4100 when the first insulation component 3000 is mounted in place, to realize the mounting and the positioning of the first insulation component 3000. After the second connection base 5000 is connected to the interior of the first connection base 4000, the second connection base 5000 cooperates with the first step surface 4100 to realize clamping of the flange portion 3100 and the flange 2100. In this way, the fixation of the first insulation component 3000 and the water delivery tube 2000 is achieved. In this embodiment, since the second connection base 5000 is connected to the interior of the first connection base 4000, the second connection base 5000 is threadedly connected to the first connection base 4000, which is more convenient and quicker and provides higher connection stability. That is, the first connection base 4000 has internal threads, and the second connection base 5000 has external threads. The connection and the fixation of the first connection base 4000 and the second connection base 5000 can be realized through rotating and twisting.

[0051] In a second aspect according to the present disclosure, a water heater is provided. As illustrated in FIG. 1 to FIG. 11, the water heater includes a magnesium rod and the above tank assembly for the water heater. The magnesium rod is disposed in the water heater tank 1000. The tank assembly for the water heater includes the water heater tank 1000 made of metal, the water delivery tube 2000 made of metal, and the first insulation component 3000. The water delivery tube 2000 is disposed in the water heater tank 1000 and in communication with the interior of the water heater tank 1000. The first insulation component 3000 is disposed between the water delivery tube 2000 and the water heater tank 1000 to insulate the water heater tank 1000 from the water delivery tube 2000.

[0052] The water delivery tube 2000 is formed of metal, such that the water delivery tube 2000 is unlikely to be deformed when the water temperature rises, and has better performance of impact resistance, aging resistance, and dry burning resistance compared with plastic. Also, on the basis that the water delivery tube 2000 is made of metal, the first insulation member 3000 is provided to insulate the water heater tank 1000 from the water delivery tube 2000, avoiding excessive consumption of the magnesium rod and protecting the water delivery tube 2000.

[0053] In an exemplary embodiment of the present disclosure, the water heater is the vertical water heater. The water heater tank 1000 has the vertical columnar structure as a whole. The water heater tank 1000 is the component for storing water. The water heater further includes the heater disposed in the water heater tank 1000. Water in the water heater tank 1000 is heated by the heater, and thus the water becomes hot water to be supplied to a user for use. The material of the water heater tank 1000 is generally metal. That is, the water heater tank 1000 is mainly made of metal, which may be copper alloy, iron alloy, aluminum alloy, or the like. For example, the water heater tank 1000 is made of stainless steel. The water heater tank 1000 is connected to the water delivery tube 2000 to realize inflow or outflow of water. It should be understood that the water delivery tube 2000 may serve as the water inlet (i.e., the water inlet tube) or the water outlet (i.e., the water outlet tube). For example, the water delivery tube 2000 is the water inlet pipe. The water delivery tube 2000 is disposed in the water heater tank 1000, and extends into the interior of the water heater tank 1000 to be in communication with the interior of the water heater tank 1000. Water from an external water source enters the interior of the water heater tank 1000 through the water delivery tube 2000.

[0054] In this embodiment, the material of the water delivery tube 2000 is metal. That is, the water delivery tube 2000 is mainly made of metal. The metal may be copper alloy, iron alloy, or aluminum alloy. For example, the water delivery tube 2000 is made of stainless steel, such that the water delivery tube 2000 is unlikely to be deformed due to the temperature, and has certain corrosion resistance and high dry burning resistance. It should be understood that the magnesium rod is disposed in the water heater tank 1000. The magnesium rod acts as the anode to be consumed to protect the water heater tank 1000. When the water delivery tube 2000 is made of metal, the magnesium rod can also provide protection for the water delivery tube 2000, which may lead to excessive consumption of the magnesium rod. For this reason, in this embodiment, the first insulation component 3000 is disposed between the water heater tank 1000 and the water delivery tube 2000 to insulate the water heater tank 1000 from the water delivery tube 2000. In this way, the magnesium rod, water, the water delivery tube 2000, and the magnesium rod cannot form a closed circuit. That is, the magnesium rod does not need to consume itself to protect the water delivery tube 2000, and thus the magnesium rod is prevented from being consumed too quickly for protecting the water delivery tube 2000. It should be understood that the first insulation component 3000 is made of an insulating material, such as silicone, rubber, plastic, or ceramic.

Under the concept of the present disclosure, any equivalent structure transformation made using the contents of the specification and the accompanying drawings of the present disclosure, or any direct or indirect application of the contents of the specification and the accompanying drawings of the present disclosure in other related fields, shall fall within the scope of the present disclosure.

[0021] Technical solutions according to embodiments of the present disclosure will be described clearly and completely below in combination with accompanying drawings of the embodiments of the present disclosure. Obviously, the embodiments described below are only part of the embodiments of the present disclosure, rather than all embodiments of the present disclosure. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present disclosure.

[0022] It should be noted that all directional indications (such as up, down, left, right, front, rear, etc.) in the embodiments of the present disclosure are only used to explain relative positions between various components, movements of various components, or the like under a predetermined posture (as illustrated in the figures). When the predetermined posture changes, the directional indications also change accordingly.

[0023] In the present disclosure, unless otherwise clearly specified and limited, terms, such as “connect”, “fix” or the like, should be understood in a broad sense. For example, it may be fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate; or internal communication of two components or interaction relationship between two components, unless otherwise clearly limited. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to specific circumstances.

[0024] In addition, descriptions, such as “first”, “second” and the like, in the present disclosure are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features associated with “first” and “second” may explicitly or implicitly include at least one of the features. In addition, the technical solutions according to various embodiments of the present disclosure can be combined, but these combinations must be based on the fact that they can be realized by those skilled in the art. When a combination of the technical solutions is contradictory or unattainable, the combination of the technical solutions neither exists nor falls within the scope of the present disclosure.

[0025] In a first aspect according to the present disclosure, a tank assembly for a water heater is provided. As illustrated in FIG. 1, FIG. 2, and FIG. 3, in some embodiments, the tank assembly for the water heater includes a water heater tank 1000 made of metal, a water delivery tube 2000, and a first insulation component 3000. The water delivery tube 2000 is disposed in the water heater tank 1000 and made of metal, and is in communication with an interior of the water heater tank 1000. The first insulation component 3000 is disposed between the water delivery tube 2000 and the water heater tank 1000 to insulate the water heater tank 1000 from the water delivery tube 2000.

[0026] The water delivery tube 2000 is designed to be made of metal, such that the water delivery tube 2000 is unlikely to be deformed when a water temperature rises, and has better performance of impact resistance, aging resistance, and dry burning resistance compared with plastic. Furthermore, on the basis that the water delivery tube 2000 is made of metal, the first insulation member 3000 is disposed to insulate the water heater tank 1000 from the water delivery tube 2000, thereby avoiding excessive consumption of a magnesium rod and protecting the water delivery tube 2000.

[0027] In an exemplary embodiment of the present disclosure, the water heater is a vertical water heater. The water heater tank 1000 has a vertical columnar structure as a whole. The water heater tank 1000 is a component for storing water. The water heater further includes a heater disposed in the water heater tank 1000. Water in the water heater tank 1000 is heated by the heater, and thus the water becomes hot water to be supplied to a user for use. The material of the water heater tank 1000 is generally metal. That is, the water heater tank 1000 is mainly made of metal, which may be copper alloy, iron alloy, aluminum alloy, or the like. For example, the water heater tank 1000 is made of stainless steel. The water heater tank 1000 is connected to the water delivery tube 2000 to realize inflow or outflow of water. It should be understood that the water delivery tube 2000 may serve as a water inlet (i.e., a water inlet tube) or a water outlet (i.e., a water outlet tube). As an example, the water delivery tube 2000 is a water inlet tube below. The water delivery tube 2000 is disposed in the water heater tank 1000, and extends into the interior of the water heater tank 1000 to be in communication with the interior of the water heater tank 1000. Water from an external water source enters the interior of the water heater tank 1000 through the water delivery tube 2000.

[0028] In the related art, the material of the water delivery tube 2000 is plastic. That is, the water delivery tube 2000 is mainly made of plastic. However, the plastic is prone to deformation when heated. Especially when the water in the water heater tank 1000 needs to be heated to a higher temperature, the water delivery tube 2000 is more prone to deformation. With an increase in a length of the water delivery tube 2000, the deformation of the water delivery tube 2000 when heated becomes more serious. Even in some cases, when the water heater is dry-burned, the water delivery tube 2000 may be directly damaged.

[0029] Therefore, in this embodiment, the material of the water delivery tube 2000 is designed to be metal. That is, the water delivery tube 2000 is mainly made of metal. The metal may be copper alloy, iron alloy, or aluminum alloy. For example, the water delivery tube 2000 is made of stainless steel, such that the water delivery tube 2000 is unlikely to be deformed due to temperature and has certain corrosion resistance and high dry burning resistance.

[0030] It should be understood that the water heater generally includes a magnesium rod disposed in the water heater tank 1000. The magnesium rod acts as an anode to be consumed to protect the water heater tank 1000. When the water delivery tube 2000 is designed to be made of metal, the magnesium rod can also form protection for the water delivery tube 2000, which may lead to excessive consumption of the magnesium rod. To this end, in this embodiment, the first insulation component 3000 is disposed between the water heater tank 1000 and the water delivery tube 2000 for insulating the water heater tank 1000 from the water delivery tube 2000. In this way, the magnesium rod, water, the water delivery tube 2000, and the magnesium rod cannot form a closed circuit. That is, the magnesium rod does not need to consume itself to protect the water delivery tube 2000, and thus the magnesium rod is prevented from being consumed too quickly to protect the water delivery tube 2000. It should be understood that the first insulation component 3000 is made of an insulating material, such as silicone, rubber, plastic, or ceramic.

[0031] As illustrated in FIG. 3, in some embodiments, the tank assembly for the water heater further includes a first connection base 4000 connected to the water heater tank 1000 to be fixed in the water heater tank 1000. The first insulation component 3000 is disposed between the first connection base 4000 and the water delivery tube 2000 to insulate the first connection base 4000 from the water delivery tube 2000.

[0032] In an exemplary embodiment of the present disclosure, the water heater tank 1000 has a thin wall, which does not facilitate the mounting of the water delivery tube 2000. Therefore, the first connection base 4000 is disposed. The first connection base 4000 has a tubular structure, and is connected to the water heater tank 1000. The first connection base 4000 is connected to the water heater tank 1000 in various ways, such as welding, screwing, engagement, or the like, to allow the first connection base 4000 to be fixed at the water heater tank 1000 and to protrude with respect to the water heater tank 1000. The first connection base 4000 provides the foundation for mounting the first insulation component 3000 and the water delivery tube 2000, which can better achieve support for the first insulation component 3000 and the water delivery tube 2000.

[0033] It should be understood that the first connection base 4000 is connected to the water heater tank 1000. The first insulation component 3000 insulates the first connection base 4000 from the water delivery tube 2000, such that the water heater tank 1000 is insulated from the water delivery tube 2000. It is precisely through this assembly that the first connection base 4000 may also be made of metal, such as copper alloy, iron alloy, or aluminum alloy. For example, the first connection base 4000 is made of stainless steel to allow the first connection base 4000 to have a high structural strength. In addition, the first connection base 4000 can be fixed to the water heater tank 1000 through welding, resulting in high connection stability.

[0034] As illustrated in FIG. 3 and FIG. 7, in some embodiments, the first insulation component 3000 extends through the first connection base 4000. The water delivery tube 2000 extends through the first insulation component 3000.

[0035] In an exemplary embodiment of the present disclosure, the water heater tank 1000 has a mounting hole 1100 in communication with the interior of the water heater tank 1000. The first connection base 4000 has a hollow tubular structure. The first connection base 4000 is connected to the water heater tank 1000 and in communication with the mounting hole 1100. That is, the first connection base 4000 is in communication with the interior of the water heater tank 1000. The first insulation component 3000 has a hollow annular structure and extends through the first connection base 4000. The water delivery tube 2000 extends through the first insulation component 3000, and extends from the mounting hole 1100 into the interior of the water heater tank 1000. Since the first insulation component 3000 extends through the first connection base 4000 and the water delivery tube 2000 extends through the first insulation component 3000, a contact area is increased and mounting stability of the water delivery tube 2000 is enhanced.

[0036] For example, as illustrated in FIG. 10 and FIG. 11, in some embodiments, the first connection base 4000 has a second step surface 4200. The second step surface 4200 is disposed outside the first connection base 4000. When the first connection base 4000 is connected to the water heater tank 1000, the first connection base 4000 is partially inserted into the mounting hole 1100 and the second step surface 4200 is abutted with a periphery of the mounting hole 1100, such that mounting and positioning of the first connection base 4000 is provided. Further, the first connection base 4000 and the water heater tank 1000 are further fastened by welding, resulting in high connection firmness.

[0037] As illustrated in FIG. 3, FIG. 4, FIG. 5, and FIG. 6, in some embodiments, the tank assembly for the water heater further includes a second connection base 5000 connected to the first connection base 4000 to fix the first insulation component 3000 and the water delivery tube 2000, thereby facilitating assembly.

[0038] In an exemplary embodiment of the present disclosure, the second connection base 5000 is connected to the first connection base 4000 to be fixed at the first connection base 4000. In addition, the second connection base 5000 is connected to the first connection base 4000 to achieve fixation of the water delivery tube 2000 and the first insulation component 3000. That is, the water delivery tube 2000 and the first insulation component 3000 are fixed between the second connection base 5000 and the first connection base 4000, which facilitates the assembly of various components. The second connection base 5000 has a tubular structure. The second connection base 5000 and the first connection base 4000 are connected to each other in a variety of ways, such as welding, screwing, engagement, or the like, to be fixed to the first connection base 4000. It should be understood that the second connection base 5000 may be configured to be connected to an external pipeline to receive water supplied from the outside.

[0039] The second connection base 5000 is connected to the first connection base 4000 in various ways to fix the water delivery tube 2000 and the first insulation component 3000. For example, the water delivery tube 2000 and the first insulation component 3000 are sandwiched between the second connection base 5000 and the first connection base 4000, which may be realized by direct contact or indirect contact. That is, the second connection base 5000 exerts a force towards the first connection base 4000 on the water delivery tube 2000 and the first insulation component 3000. The first connection base 4000 exerts a force towards the second connection base 5000 on the water delivery tube 2000 and the first insulation component 3000, to realize clamping on the water delivery tube 2000 and the first insulation component 3000. That is, fixation and mounting of the water delivery tube 2000 and the first insulation component 3000 is realized, which facilitates assembly and has high connection firmness.

[0040] Further, on the basis that the water delivery tube 2000 and the first insulation component 3000 are sandwiched between the second connection base 5000 and the first connection base 4000, the tank assembly for the water heater further includes a second insulation component 6000. As illustrated in FIG. 4 and FIG. 6, the second insulation component 6000 is disposed between the second connection base 5000 and the water delivery tube 2000 to allow the second connection base 5000 to be insulated from the water delivery tube 2000. In this case, the second connection base 5000 may also be made of metal, such as copper alloy, iron alloy, or aluminum alloy, for example, stainless steel, such that the second connection base 5000 has a higher structural strength. It should be understood that when the second insulation component 6000 is disposed between the second connection base 5000 and the water delivery tube 2000, the second connection base 5000 and the first insulation component 3000 may be in direct contact with each other, or the second insulation component 6000 is disposed between the water delivery tube 2000 and the second connection base 5000 and between the first insulation component 3000 and the second connection base 5000. For example, the second insulation component 6000 is formed integrally. The second insulation component 6000 is made of an insulating material, such as silicone, rubber, plastic, ceramic, or the like. The second insulation component 6000 is formed to be elastically deformable, such as silicone or rubber, which is more conducive to sealing.

[0041] As illustrated in FIG. 4, FIG. 7, FIG. 8, and FIG. 9, in some embodiments of the present disclosure, the first insulation component 3000 is provided with a flange portion 3100 at an end of the first insulation component 3000. The first connection base 4000 has a first step surface 4100. The flange portion 3100 is sandwiched between the first step surface 4100 and the second connection base 5000.

[0042] In an exemplary embodiment of the present disclosure, when the first insulation component 3000 is assembled to the first connection base 4000, the first insulation component 3000 extends through the first connection base 4000. It should be understood that the first insulation component 3000 is mounted at the first connection base 4000 through insertion. The first step surface 4100 is disposed at the first connection base 4000, such that the flange portion 3100 of the first insulation component 3000 is abutted with the first step surface 4100 when the first insulation component 3000 is mounted in place, to realize mounting and positioning of the first insulation component 3000. The second connection base 5000 is then connected to the first connection base 4000. The flange portion 3100 is sandwiched between the second connection base 5000 and the first step surface 4100 to fix the first insulation component 3000.

[0043] In some embodiments, the first insulation component 3000 is in an interference fit with the first connection base 4000 to prevent water leakage between the first insulation component 3000 and the first connection base 4000 to better realize fixation of the first insulation component 3000.

[0044] For example, the first insulation component 3000 includes a sleeve portion 3200 and the flange portion 3100. The flange portion 3100 is disposed at an end of the sleeve portion 3200, that is, the flange portion 3100 protrudes relative to the sleeve portion 3200 in a radial direction of the flange portion 3100. The water delivery tube 2000 extends through the sleeve portion 3200. The flange portion 3100 is configured to be abutted with the first step surface 4100. The sleeve portion 3200 is in an interference fit with the first connection base 4000 when the first insulation component 3000 extends through the first connection base 4000. In particular, the first insulation component 3000 may be formed to be elastically deformable. When the first insulation component 3000 is mounted to the first connection base 4000, the first insulation component 3000 has a certain degree of deformation to be in an interference fit with the first connection base 4000 to eliminate a gap between the first insulation component 3000 and the first connection base 4000 as much as possible, preventing water leakage.

[0045] As illustrated in FIG. 7 and FIG. 8, in some embodiments, the sleeve portion 3200 has a plurality of sealing teeth 3210. The plurality of sealing teeth means two or more sealing teeth. That is, at least two sealing teeth 3210 are provided. The plurality of sealing teeth 3210 are arranged at intervals in a length direction of the sleeve portion 3200. When the first insulation component 3000 extends through the first connection base 4000, the plurality of sealing teeth 3210 is abutted with the first connection base 4000 to improve sealing performance.

[0046] In an exemplary embodiment of the present disclosure, the sealing teeth 3210 of the first insulation component 3000 are disposed at a peripheral surface, in particular at a peripheral surface of the sleeve portion 3200 of the first insulation component 3000. The sleeve portion 3200 is surrounded by the sealing teeth 3210. When the assembly of the first connection base 4000, the first insulation component 3000, and the water delivery tube 2000 is completed, the sleeve portion 3200 is located between the first connection base 4000 and the water delivery tube 2000, such that the plurality of sealing teeth 3210 is abutted with the first connection base 4000. With the plurality of sealing teeth 3210 arranged at intervals, the sealing performance between the first insulation component 3000 and the first connection base 4000 is improved.

[0047] As illustrated in FIG. 4, FIG. 6, and FIG. 7, in some embodiments, the water delivery tube 2000 is provided with a flange 2100 at an end of the water delivery tube 2000. The flange 2100 is configured to be abutted with an end portion of the first insulation component 3000. In an exemplary embodiment of the present disclosure, the water delivery tube 2000 is mounted to the first insulation component 3000 through insertion so that the water delivery tube 2000 extends through the first insulation component 3000. With the flange 2100 disposed at the end of the water delivery tube 2000, the flange 2100 is abutted with the end portion of the first insulation component 3000 when the water delivery tube 2000 is mounted in place. For example, the flange 2100 is abutted with the flange portion 3100 of the first insulation component 3000, forming mounting and positioning of the water delivery tube 2000. For example, the flange 2100 is abutted with the end portion (i.e., the flange portion 3100) of the first insulation component 3000 in a gravity direction. When the second connection base 5000 is connected to the first connection base 4000, the second connection base 5000 cooperates with the first step surface 4100 to sandwich the flange 2100 and the flange portion 3100, realizing fixation of the water delivery tube 2000 and the first insulation component 3000.

[0048] In some embodiments, the first insulation component 3000 is in an interference fit with the water delivery tube 2000, which can better realize fixation of the water delivery tube 2000 and prevent water leakage between the water delivery tube 2000 and the first insulation component 3000. For example, the first insulation component 3000 includes a sleeve portion 3200 and the flange portion 3100. The flange portion 3100 is disposed at an end of the sleeve portion 3200, that is, the flange portion 3100 protrudes relative to the sleeve portion 3200 in the radial direction of the flange portion 3100. The water delivery tube 2000 extends through the sleeve portion 3200. The sleeve portion 3200 is in an interference fit with the water delivery tube 2000.

[0049] Further, the first insulation component 3000 is elastically deformable. The water delivery tube 2000 has a diameter greater than an inner diameter of the first insulation component 3000. When the water delivery tube 2000 extends through the first insulation component 3000, the first insulation component 3000 has a certain degree of deformation to be in an interference fit with the water delivery tube 2000 to eliminate the gap between the first insulation component 3000 and the water delivery tube 2000 as much as possible, preventing water leakage.

[0050] As illustrated in FIG. 4 to FIG. 6, in some embodiments, the first step surface 4100 is disposed inside the first connection base 4000. The second connection base 5000 is connected to an interior of the first connection base 4000 to cooperate with each other, to achieve clamping for the flange portion 3100. In an exemplary embodiment of the present disclosure, when the first insulation component 3000 is assembled to the first connection base 4000, the first insulation component 3000 extends through the first connection base 4000. That is, the first insulation component 3000 is mounted to the interior of the first connection base 4000. It should be understood that the first insulation component 3000 is mounted to the interior of the first connection base 4000 through insertion. The first step surface 4100 is disposed at the interior of the first connection base 4000, the flange portion 3100 of the first insulation component 3000 is abutted with the first step surface 4100 when the first insulation component 3000 is mounted in place, to realize the mounting and the positioning of the first insulation component 3000. After the second connection base 5000 is connected to the interior of the first connection base 4000, the second connection base 5000 cooperates with the first step surface 4100 to realize clamping of the flange portion 3100 and the flange 2100. In this way, the fixation of the first insulation component 3000 and the water delivery tube 2000 is achieved. In this embodiment, since the second connection base 5000 is connected to the interior of the first connection base 4000, the second connection base 5000 is threadedly connected to the first connection base 4000, which is more convenient and quicker and provides higher connection stability. That is, the first connection base 4000 has internal threads, and the second connection base 5000 has external threads. The connection and the fixation of the first connection base 4000 and the second connection base 5000 can be realized through rotating and twisting.

[0051] In a second aspect according to the present disclosure, a water heater is provided. As illustrated in FIG. 1 to FIG. 11, the water heater includes a magnesium rod and the above tank assembly for the water heater. The magnesium rod is disposed in the water heater tank 1000. The tank assembly for the water heater includes the water heater tank 1000 made of metal, the water delivery tube 2000 made of metal, and the first insulation component 3000. The water delivery tube 2000 is disposed in the water heater tank 1000 and in communication with the interior of the water heater tank 1000. The first insulation component 3000 is disposed between the water delivery tube 2000 and the water heater tank 1000 to insulate the water heater tank 1000 from the water delivery tube 2000.

[0052] The water delivery tube 2000 is formed of metal, such that the water delivery tube 2000 is unlikely to be deformed when the water temperature rises, and has better performance of impact resistance, aging resistance, and dry burning resistance compared with plastic. Also, on the basis that the water delivery tube 2000 is made of metal, the first insulation member 3000 is provided to insulate the water heater tank 1000 from the water delivery tube 2000, avoiding excessive consumption of the magnesium rod and protecting the water delivery tube 2000.

[0053] In an exemplary embodiment of the present disclosure, the water heater is the vertical water heater. The water heater tank 1000 has the vertical columnar structure as a whole. The water heater tank 1000 is the component for storing water. The water heater further includes the heater disposed in the water heater tank 1000. Water in the water heater tank 1000 is heated by the heater, and thus the water becomes hot water to be supplied to a user for use. The material of the water heater tank 1000 is generally metal. That is, the water heater tank 1000 is mainly made of metal, which may be copper alloy, iron alloy, aluminum alloy, or the like. For example, the water heater tank 1000 is made of stainless steel. The water heater tank 1000 is connected to the water delivery tube 2000 to realize inflow or outflow of water. It should be understood that the water delivery tube 2000 may serve as the water inlet (i.e., the water inlet tube) or the water outlet (i.e., the water outlet tube). For example, the water delivery tube 2000 is the water inlet pipe. The water delivery tube 2000 is disposed in the water heater tank 1000, and extends into the interior of the water heater tank 1000 to be in communication with the interior of the water heater tank 1000. Water from an external water source enters the interior of the water heater tank 1000 through the water delivery tube 2000.

[0054] In this embodiment, the material of the water delivery tube 2000 is metal. That is, the water delivery tube 2000 is mainly made of metal. The metal may be copper alloy, iron alloy, or aluminum alloy. For example, the water delivery tube 2000 is made of stainless steel, such that the water delivery tube 2000 is unlikely to be deformed due to the temperature, and has certain corrosion resistance and high dry burning resistance. It should be understood that the magnesium rod is disposed in the water heater tank 1000. The magnesium rod acts as the anode to be consumed to protect the water heater tank 1000. When the water delivery tube 2000 is made of metal, the magnesium rod can also provide protection for the water delivery tube 2000, which may lead to excessive consumption of the magnesium rod. For this reason, in this embodiment, the first insulation component 3000 is disposed between the water heater tank 1000 and the water delivery tube 2000 to insulate the water heater tank 1000 from the water delivery tube 2000. In this way, the magnesium rod, water, the water delivery tube 2000, and the magnesium rod cannot form a closed circuit. That is, the magnesium rod does not need to consume itself to protect the water delivery tube 2000, and thus the magnesium rod is prevented from being consumed too quickly for protecting the water delivery tube 2000. It should be understood that the first insulation component 3000 is made of an insulating material, such as silicone, rubber, plastic, or ceramic.
